The clinical diagnosis of tubulointerstitial nephritis and uveitis (TINU) syndrome combined with Fanconi syndrome is relatively rare. The paper reports a 47-year-old female patient of TINU syndrome with hypokalemia, hypophosphatemia, hypouricemia and renal impairment as initial symptoms followed by uveitis. Serological tests showed that the patient also met the diagnostic criteria of Fanconi syndrome. Renal tissue pathology confirmed tubular interstitial injury, manifested as interstitial nephritis with acute tubular injury. Ophthalmic examination confirmed iritis in the right eye. After excluding other primary diseases, the patient was diagnosed as TINU syndrome with Fanconi syndrome. After glucocorticoid therapy, ocular symptoms, renal impairment and electrolyte disturbance were significantly improved.

Objective To compare the principles,methods and applications of provider-to-population ratios method,gravity-based model,two-step floating catchment area(2SFCA)method and improved two-step floating catchment area method for evaluating the spatial accessibility to healthcare services.Methods Taking the spatial accessibility to maternal and child healthcare services in Nanning prefecture for example,we collected data on vector map,transportation network,population size,and the number of health professionals in maternal and child health institutions.Provider-to-population ratios method,gravity-based model,2SFCA method and improved 2SFCA method were applied to evaluate the spatial accessibility to maternal and child healthcare services,on the scales of county level,township level and village level,respectively.Results The four models showed that the spatial heterogeneity of spatial accessibility to maternal and child health services was significant,and the spatial accessibility was gradually decreased from urban areas of Nanning to rural areas.However,regions with high spatial accessibility and regions with low spatial accessibility,decreasing trend in spatial accessibility across regions,the median and inter quartile range of spatial accessibility were different across the four models.Conclusion The practical significance in evaluating spatial accessibility to healthcare services for provider-to-population ratios method,gravity-based model,2SFCA method and improved 2SFCA method was different,yet the spatial accessibility varied somewhat across the four models.Thus,integrating findings of the four models based on multi space scales is strongly recommended to evaluate the spatial accessibility to healthcare services comprehensively and robustly.

Clinical data of 455 patients with extensive burns who met the inclusion criteria and were admitted to the burn centers of 3 hospitals from January 2016 to June 2022 were collected, including 202 patients from the First Affiliated Hospital of Nanchang University, 179 patients from the Second Affiliated Hospital of Zhejiang University School of Medicine, and 74 patients from the First Affiliated Hospital of Anhui Medical University. The following data were collected from patients during their hospitalization, including infusion of red blood cells, plasma, and platelets during hospitalization; age, gender, body mass index, combined underlying diseases, cause of injury, time of admission after injury, type of admission, total burn area, full-thickness burn area, combination of inhalation injury, combination of other trauma, and combination of pulmonary edema; the blood lactic acid, serum creatinine, total bilirubin, and albumin values within 24 h of admission; combination of bloodstream, wound, lung, and urinary tract infection, and combination of sepsis; the number of escharectomy or tangential excision and skin grafting surgery (hereinafter referred to as surgery) and total surgical blood loss volume; occurrence of hemoglobin<70 g/L, admission to intensive care unit (ICU), conduction of mechanical ventilation and continuous renal replacement therapy (CRRT), length of hospital stay, and prognosis were recorded. In 602 surgeries of patients within 14 days after injury, data including area of escharectomy or tangential excision and skin graft harvesting, duration of operation, and surgical blood loss volume per surgery, operation site, and use of tourniquet and wound graft were collected. Data were statistically analyzed with Mann-Whitney U test, Kruskal-Wallis H test, and Spearman correlation analysis. Combined with the results of single factor analysis and clinical significance, multiple linear regression analysis was performed to screen the independent influencing factors of red blood cell infusion volume and plasma infusion volume, as well as blood loss volume per surgery. Results:During the whole hospitalization period, 437 (96.0%) patients received blood transfusion therapy, including 435 (95.6%) patients, 410 (90.1%) patients, and 73 (16.0%) patients who received transfusion of plasma, red blood cells, and platelets, respectively. The patients were mainly male, aged 18 to 92 years. There were statistically significant differences in the plasma infusion volume among patients with different combination of underlying disease, combination of inhalation injury, combination of other trauma, combination of pulmonary edema, combination of bloodstream infection, combination of wound infection, combination of lung infection, combination of urinary tract infection, combination of sepsis, occurrence of hemoglobin value <70 g/L, admission to ICU, conduction of mechanical ventilation, and conduction of CRRT (with Z values of -2.06, -4.67, -2.11, -6.13, -9.56, -4.93, -8.08, -4.78, -9.12, -6.55, -9.37, -11.46, and -7.17, respectively, P<0.05). The total burn area, full-thickness burn area, blood lactic acid value within 24 h of admission, serum creatinine value within 24 h of admission, albumin value within 24 h of admission, number of surgeries, and total surgical blood loss volume were correlated with the plasma infusion volume of patients (with r values of 0.39, 0.51, 0.14, 0.28, -0.13, 0.47, and 0.56, respectively, P<0.05).There were statistically significant differences in the red blood cell infusion volume among patients with different gender, combination of inhalation injury, combination of other trauma, combination of pulmonary edema, combination of bloodstream infection, combination of wound infection, combination of lung infection, combination of urinary tract infection, combination of sepsis, occurrence of hemoglobin value <70 g/L, admission to ICU, conduction of mechanical ventilation, and conduction of CRRT (with Z values of -2.00, -4.34, -3.10, -4.22, -8.24, -7.66, -8.62, -4.75, -7.42, -9.36, -6.12, and -8.31, -6.64, respectively, P<0.05). The age, total burn area, full-thickness burn area, blood lactic acid value within 24 h of admission, serum creatinine value within 24 h of admission, total bilirubin value within 24 h of admission, number of surgeries, and total surgical blood loss volume were correlated with the red blood cell infusion volume of patients (with r values of 0.12, 0.22, 0.49, 0.09, 0.18, 0.13, -0.15, 0.69, and 0.77, respectively, P<0.05). Combined underlying diseases, full-thickness burn area, combined pulmonary edema, serum creatinine value within 24 h of admission, combined sepsis, conduction of CRRT, number of surgeries, and total surgical blood loss volume were the independent influencing factors for plasma infusion volume during hospitalization in patients with extensive burns (with standardized regression coefficients of 0.09, 0.16, 0.12, 0.07, 0.11, 0.15, 0.31, and 0.26, respectively, P<0.05). Female, full-thickness burn area, serum creatinine value within 24 h of admission, combined sepsis, occurrence of hemoglobin value <70 g/L, conduction of CRRT, and total surgical blood loss volume were the independent influencing factors for red blood cell infusion volume during hospitalization in patients with extensive burns (with standardized regression coefficients of 0.10, 0.12, 0.10, 0.11, 0.05, 0.19, and 0.54, respectively, P<0.05). There were statistically significant differences in blood loss volume per surgery of patients with different surgical site and wound graft (with Z values of -2.54 and -2.27, respectively, P<0.05). The area of escharectomy or tangential excision and skin graft harvesting and duration of operation were correlated with the blood loss volume per surgery of patients (with r values of 0.40 and 0.21, respectively, P<0.05). The area of escharectomy or tangential excision and skin graft harvesting, duration of operation, and active wound grafts were the independent influencing factors for blood loss volume per surgery of patients with extensive burns (with standardized regression coefficients of 0.41, 0.16, and 0.12, respectively, P<0.05). Conclusions:The major factors influencing blood transfusion status in patients with extensive burns are female, combined underlying diseases, full-thickness burn area, serum creatinine value within 24 h of admission, combined pulmonary edema, occurrence of hemoglobin value <70 g/L, combined sepsis, conduction of CRRT, number of surgery, and total surgical blood loss volume. In addition, the area of escharectomy or tangential excision and skin graft harvesting, duration of operation, and active wound grafts indirectly affect the patient's blood transfusion status by affecting the blood loss volume per surgery.

Objective:To explore the influence of parental compliance on the treatment of hypertrophic scars in burn children.Methods:A retrospective cohort study method was used. From June 2014 to June 2019, 49 children with post-burn hypertrophic scars who met the inclusion criteria and visited the outpatient department of the Department of Burns of the First Affiliated Hospital of Anhui Medical University were included in this study. In the follow-up of 9 months, according to the registration form and the results of the compliance questionnaire for parents, the children were divided into good compliance group (34 cases, 21 males and 13 females, aged 2.0 (2.0, 3.5) years) and poor compliance group (15 cases, 6 males and 9 females, aged 3.0 (2.0, 4.0) years). At the first attendance and in the follow-up of 3, 6, and 9 months, the scar scores of children in good compliance group were evaluated by Vancouver Scar Scale (VSS). At the first attendance and in the follow-up of 9 months, the scar scores of children in poor compliance group were evaluated by VSS. At the first attendance and in the follow-up of 9 months, the scar pruritus scores of children in the 2 groups were evaluated by Verbal Rating Score (VRS). Data was statistically analyzed with chi-square test, Wilcoxon rank sum test, Mann-Whitney U test, independent sample t test, and paired sample t test. Results:At the first attendance, the color, vascular distribution, softness, and thickness scores, and total score in VSS scoring of scars of children in the two groups were similar ( Z=0.834, 0.026, 0.837, 0.076, 1.074, P>0.05). In the follow-up of 9 months, the softness and thickness scores, and total score in VSS scoring of scars of children in good compliance group were significantly lower than those in poor compliance group ( Z=5.518, 4.732, 5.042, P<0.01). Compared with those in the first attendance, the color, vascular distribution, softness, and thickness scores, and total score in VSS scoring of scars of children in good compliance group were significantly decreased in the follow-up of 9 months ( Z=5.241, 5.273, 5.214, 5.245, 3.451, P<0.01); the color and vascular distribution scores, and total score in VSS scoring of scars of children in poor compliance group were significantly decreased in the follow-up of 9 months ( Z=3.606, 3.542, 3.448, P<0.01). At the first attendance, the VRS score of scar pruritus of children in good compliance group was 6.00 (5.00, 6.25) points, which was similar to (5.47±1.69) points in poor compliance group ( Z=0.607, P>0.05). In the follow-up of 9 months, the VRS score of scar pruritus of children in good compliance group was 1.00 (1.00, 1.25) points, which was significantly lower than (3.27±1.71) points in poor compliance group ( Z=2.606, P<0.01). Compared with those in the first attendance, the VRS score of scar pruritus of children in good compliance group was significantly decreased in the follow-up of 9 months ( Z=4.002, P<0.01), while there was no obvious change in poor compliance group in the follow-up of 9 months ( t=3.550, P>0.05). Conclusions:Under the same treatment plan, good parental compliance has a positive effect on the treatment of hypertrophic scars in burn children decreasing the degree of scar hyperplasia and pruritus.

Objective:To evaluate the safety and efficacy of the technique of minimally invasive separation surgery with small incision and free hand screw placement in patients with spinal metastases.Methods:Retrospectively reviewed the clinical data of 49 consecutive patients from May 2019 to December 2019 who underwent minimally invasive separation surgery with small incision and free hand screw placement for metastatic spinal tumors. Among them, there were 21 males with an average age of 55.62±2.97 years (range: 26-75 years) and 28 females with an average age of 52.50±1.76 years (range: 34-72 years). For patients who have primary tumor history with multiple metastases, routine pre-operative biopsy is not required; but for patients whose primary tumor is unknown and who have no history of tumor, pre-operative biopsy diagnosis is required. Before operation, Karnofsky Performance status (KPS) scoring system was used to evaluate the general condition of patients, Spinal Instability Neoplastic Score (SINS) scoring system was used to evaluate the spine stability, epidural spinal cord compression (ESCC) grading system was performed to access the degree of spinal cord nerve compression, and Frankel grading system was used to evaluate the neurological function. For patients who meet inclusion and exclusion criteria ware performed for decompression and internal fixation by a minimally invasive separation surgery with small incision and free hand screw placement. The demographic, neurological function, complications and perioperative data were collected and analyzed, including pre-operation neurological function, operation time, intraoperative blood loss, postoperative suction drainage, drainage tube extraction time, complications rates, hospital stay, and assessment of neurological recovery at 4 weeks after surgery.Results:Preoperative coil embolization was performed in 1 patient with kidney cancer. The mean intraoperative blood loss was 748.60±79.39 ml. Comparison of intraoperative blood loss of 12 rich blood supply (liver cancer, kidney cancer, thyroid cancer) and 37 poor blood supply spine metastases (970.80 ml vs 676.50 ml) was not statistically significant ( P>0.05). The average operation time was 213.40±9.87 min. The operation involved 1 segment was performed in 41 patients (83.67%) and 8 patients had separation of 2 or more segments. The post-operative drainage before discharge was 494.02±63.30 ml. The average drainage tube retention time was 4.50±0.26 d and the average length of hospital stay was 7.35±0.38 d. The post-operative hospitalization was 5.31±0.29 d. 79.59% of patients had the neurological functions of Frankel grade C and D before surgery and 95.92% of patients exhibited stable and improved function at 4 weeks after surgery which was significantly improved comparing with that before surgery ( P<0.05). The complications occurred were dural rupture (1 case), infection (1 case) and hematoma (1 case). Comparison:The minimally invasive separation surgery with small incision and free hand screw placement could achieve less trauma, low complications rate, rapid postoperative recovery. It is also comparable to the traditional open separation surgery in terms of spinal stability and improvement of neurological functions. It is an excellent alternative for patient with spinal metastases.

Long-term primary culture of mammalian cells has been always difficult due to unavoidable senescence. Conventional methods for generating immortalized cell lines usually require manipulation of genome which leads to change of important biological and genetic characteristics. Recently, conditional reprogramming (CR) emerges as a novel next generation tool for long-term culture of primary epithelium cells derived from almost all origins without alteration of genetic background of primary cells. CR co-cultures primary cells with inactivated mouse 3T3-J2 fibroblasts in the presence of RHO-related protein kinase (ROCK) inhibitor Y-27632, enabling primary cells to acquire stem-like characteristics while retain their ability to fully differentiate. With only a few years' development, CR shows broad prospects in applications in varied areas including disease modeling, regenerative medicine, drug evaluation, drug discovery as well as precision medicine. This review is thus to comprehensively summarize and assess current progress in understanding mechanism of CR and its wide applications, highlighting the value of CR in both basic and translational researches and discussing the challenges faced with CR.

Objective:To explore the effects of early exogenous L-carnitine supplementation on renal function in severely scalded rats.Methods:According to the random number table, sixty-six adult female Sprague-Dawly rats were divided into healthy control group ( n=6), scald alone group ( n=30), and scald+ carnitine group ( n=30). In the latter two groups, the rats were inflicted with full-thickness scald of 30% total body surface area on the back, and the lactated Ringer′s solution was injected through the tail vein for resuscitation immediately after scald. At post injury hour (PIH) 1, rats in scald+ carnitine group were intraperitoneally injected with 100 mg/mL L-carnitine solution 400 mg/kg, while rats in scald alone group were intraperitoneally injected with the same volume of normal saline. Rats in these two groups were injected once every 24 hours thereafter. Six rats were taken from each of scald alone group and scald+ carnitine group to collect the renal tissue and abdominal aorta blood at PIH 6, 12, 24, 48, and 72, respectively. The serum content of total protein, albumin, urea nitrogen, creatinine, and cystatin C were determined by the automatic biochemical analyzer. Renal tissue was stained with hematoxylin-eosin to observe histopathological changes. Rats in healthy control group did not undergo any treatment, and their renal tissue and blood sample were extracted and analyzed in the same way as those of severely scalded rats. Data were statistically analyzed with one-way analysis of variance and Bonferroni method. Results:(1) The serum content of total protein and albumin of rats in scald alone group at each time point after injury was significantly lower than that in healthy control group ( P<0.05). The serum content of total protein of rats in scald+ carnitine group was significantly higher than that in scald alone group at PIH 12 and 24 ( P<0.05), and the serum content of albumin of rats in scald+ carnitine group was significantly higher than that in scald alone group at PIH 12 ( P<0.05). The serum content of total protein and albumin of rats in scald alone group and scald+ carnitine group showed a trend of decrease followed by an increase, with the lowest value at PIH 24. (2) The serum content of urea nitrogen and creatinine of rats in scald alone group at each time point after injury was significantly higher than that of healthy control group ( P<0.05). The serum content of urea nitrogen of rats in scald+ carnitine group was significantly lower than that in scald alone group at PIH 6, 48, and 72 ( P<0.05). The serum content of creatinine of rats in scald+ carnitine group was significantly lower than that in scald alone group at PIH 12, 24, 48, and 72 ( P<0.05). The serum content of urea nitrogen and creatinine of rats in scald alone group and scald+ carnitine group showed a trend of increase followed by a decrease, with the peak value at PIH 12. (3) The serum content of cystatin C of rats in scald alone group at PIH 6, 12, 24, 48, and 72 was (0.250±0.030), (0.330±0.070), (0.300±0.060), (0.240±0.060), and (0.190±0.030) mg/L, and the content at the first 4 time points were significantly higher than (0.170±0.020) mg/L of healthy control group ( P<0.05). At PIH 24, the serum content of cystatin C of rats in scald+ carnitine group was (0.210±0.040) mg/L, which was significantly lower than that of scald alone group ( P<0.05). The serum content of cystatin C of rats in scald alone group and scald+ carnitine group showed a trend of increase followed by a decrease, with the peak value at PIH 12. (4) The renal tissue of rats in healthy control group was almost normal, and the degree of renal tissue injury of rats in scald+ carnitine group was lighter than that in scald alone group at each time point after injury. At PIH 24, the renal tissue of rats in scald alone group showed extensive swelling of the renal tubular epithelial cells, vacuolar degeneration and necrosis, loss of brush borders, and nuclear shrinkage; more than 2/3 of the renal tubular cell nuclei disappeared, the tubular lumen was narrowed, necrotic exfoliated cells could be seen in the lumen, and edema and inflammatory cell infiltration could be seen in the renal interstitial. Compared with those of scald alone group, significantly reduced severity of edema and necrosis of renal tubular epithelial cells, as well as less inflammatory cell infiltration were observed in the renal tissue of rats in scald+ carnitine group. Conclusions:Early supplement of L-carnitine in severely scalded rats can reduce the damage of renal cells, accelerate the restoration of the content of total protein, albumin, urea nitrogen, creatinine, and cystatin C, thereby maintaining the stability of renal function metabolism level.

Objective: To analyze the reasons for failure of Meek micro-skin grafting in children with severe burns and to observe the clinical effects of the treatment measures. Methods: Thirty children with severe burns hospitalized in the First Affiliated Hospital of Anhui Medical University (hereinafter referred to as the author′s affiliation) from January 2012 to January 2018, conforming to the inclusion criteria were included to failed skin graft group. Children in failed skin graft group were performed with Meek micro-skin grafting operation and the operation failed, including 17 males and 13 females aged 1 to 12 year(s). Thirty children with severe burns hospitalized in the author′s affiliation during the same period of time, conforming to the inclusion criteria, were included to successful skin graft group. Children in successful skin graft group were performed with Meek micro-skin grafting operation and the operation succeeded, including 16 males and 14 females aged 1 to 12 year(s). Main treatment measures and effects before operation, area and survival rate of Meek micro-skin graft, infected pathogens status, selection status of sensitive antibiotics, preoperative nutrition status, and wound infection status in plum rain season of children in the two groups, and nutritional status before and after strengthening nutritional support of postoperative surviving children in failed skin graft group were analyzed retrospectively. Data were processed with chi-square test and t test. Results: (1) The numbers of children in the two groups performed with main treatment measures of dilatation and anti-shock, tracheotomy intubation, ventilator-assisted respiration, and limb incision decompression after admission were close (χ²=0, 0.016, 0.025, 0.009, P>0.05). After taking the above-mentioned main treatment measures, effects of correcting shock, preventing asphyxia, correcting breathing difficulty, and improving peripheral circulation of limb were achieved. (2) The area of Meek micro-skin grafting of children in successful skin graft group was (20.6±2.5)% total body surface area (TBSA), close to (21.2±2.2)% TBSA in failed skin graft group (t=0.534, P>0.05). The survival rate of Meek micro-skin graft of children in successful skin graft group was (79±5)%, significantly higher than (26±3)% in failed skin graft group (t=2.956, P<0.01). (3) The microbial culture of wound secretion of 5 (16.67%) children in 30 patients in successful skin graft group was positive, with Pseudomonas aeruginosa of 2 children, and Escherichia coli, Staphylococcus aureus, and Aspergillus of one patient respectively. As children in successful skin graft group were with no symptom of systemic infection, no blood microbial culture was done. The microbial culture of wound secretion of 30 (100.00%) children in 30 patients in failed skin graft group was positive, and blood microbial culture of 8 (26.67%) children was positive. The main pathogen was Pseudomonas aeruginosa of 11 (36.67%) children in 8 pathogens caused infection with gram-negative bacteria of 22 (73.33%), gram-positive bacteria of 11 (36.67%) children, and fungi of 6 (20.00%) children. (4) Ten kinds of sensitive antibiotics such as cephalosporins, glycopeptides, carbapenems, and tetracyclines antibiotics were used in children in failed skin graft group, of which the use rate of imipenem of 9 (30.00%) was the highest. Only 4 kinds of sensitive antibiotics such as ceftazidime were used in 30 children in successful skin graft group. (5) The preoperative levels of albumin and prealbumin of children in successful skin graft group were (32±4) g/L and (133±41) mg/L respectively, significantly higher than (27±4) g/L and (93±35) mg/L in failed skin graft group (t=5.090, 4.064, P<0.01). The albumin and prealbumin levels of postoperative surviving children in failed skin graft group after nutritional support treatment were (35±4) g/L and (168±49) mg/L, significantly higher than (27±4) g/L and (94±38) mg/L before nutritional support treatment (t=6.911, 6.315, P<0.01). (6) Wound infection of 9 children in 30 children with wound infection in failed skin graft group happened in the plum rain season, and fungi infection of 3 children in 6 children with fungi infection happened in the plum rain season. Wound infection of 2 children in 5 children with wound infection in successful skin graft group happened in the plum rain season, and the only one children with fungi infection happened in the plum rain season. Conclusions The main reasons for the failure of Meek micro-skin grafting in children with severe burns include infection, nutrition, and season factors, etc. Measures of strengthening wound dressing change, reasonable use of sensitive antibiotics to control infection, internal and external intestinal nutritional support, and reducing disturbance of the plum rain season by enhancing ventilation are effective and worthy of clinical promotion.

Objective: To explore the influence of three-level collaboration network of pediatric burns in Anhui province on treatment effects of burn children. Methods: The data of medical records of pediatric burn children transferred from Lu′an People′s Hospital and Fuyang People′s Hospital to the First Affiliated Hospital of Anhui Medical University from January 2014 to December 2015 and January 2016 to September 2017 (before and after establishing three-level collaboration network of pediatric burns treatment) were analyzed: percentage of transferred burn children to hospitalized burn children in corresponding period, gender, age, burn degree, treatment method, treatment result, occurrence and treatment result of shock, and operative and non-operative treatment time and cost. Rehabilitation result of burn children transferred back to local hospitals in 2016 and 2017. Data were processed with t test, chi-square test, Mann-Whitney U test, and Fisher′s exact test.

The incidence of shock of children with severe burns transferred from January 2014 to December 2015 was 6.0% (4/67), and 3 children among them were cured. The incidence of shock of children with severe burns transferred from January 2016 to September 2017 was 3.9% (2/51), and both children were cured. The incidences and cures of shock of children with severe burns transferred from the two periods of time were close (χ²=0.006, P>0.05). Incidence of shock of children with extremely severe burns transferred from January 2014 to December 2015 was 57.1% (32/56), significantly higher than that of burn children transferred from January 2016 to September 2017 [34.5% (10/29), χ²=3.925, P<0.05]. Shock of 25 children with extremely severe burns transferred from January 2014 to December 2015 were cured, and shock of 9 children with extremely severe burns transferred from January 2016 to September 2017 were cured. The cures of shock of children with extremely severe burns transferred from the two periods of time were close ( χ²=0.139, P>0.05). (5) Time of operative treatment of children with moderate, severe, and extremely severe burns transferred from January 2014 to December 2015 was obviously longer than that of burn children transferred from January 2016 to September 2017 (t=2.335, 2.065, 2.310, P<0.05). Time of operative treatment of children with mild burns transferred from the two periods of time was close (Z=-0.417, P>0.05). Costs of operative treatment of children with moderate and severe burns transferred from January 2014 to December 2015 were significantly more than those of burn children transferred from January 2016 to September 2017 (Z=-3.324, t=2.167, P<0.05). Costs of operative treatment of children with mild and extremely severe burns transferred from the two periods of time were close (t=0.627, 0.808, P>0.05). (6)Time of non-operative treatment of children with mild, moderate, and severe burns transferred from January 2014 to December 2015 was obviously longer than that of burn children transferred from January 2016 to September 2017 (t=2.335, Z=-2.095, t=2.152, P<0.05). Time of non-operative treatment of children with extremely severe burns transferred from the two periods of time was close (t=0.450, P>0.05). Costs of non-operative treatment of children with moderate and severe burns transferred from January 2014 to December 2015 were obviously higher than those of burn children transferred from January 2016 to September 2017 (Z=-2.164, t=2.040, P<0.05). Costs of non-operative treatment of children with mild and extremely severe burns transferred from the two periods of time were close (t=0.146, 1.235, P>0.05). (7) Sixty-seven burn children transferred from January 2016 to September 2017 were transferred back to local hospitals for rehabilitation under the guidance of experts of the First Affiliated Hospital of Anhui Medical University, with 25 patients in 2016 and 42 patients in 2017. Effective rehabilitation rates of burn children transferred back to local hospitals for rehabilitation in 2016 and 2017 were both 100%. Conclusions The three-level collaboration network of pediatric burns treatment in Anhui province can effectively increase cure rate of children with mild, moderate, and severe burns, reduce incidence of shock of children with extremely severe burns, shorten time of operative treatment of burn children with moderate, severe, and extremely severe burns, and time of non-operative treatment of children with mild, moderate, and severe burns, reduce treatment costs of children with moderate and severe burns, and improve rehabilitation effectiveness of children transferred from Lu′an People′s Hospital and Fuyang People′s Hospital to the the First Affiliated Hospital of Anhui Medical University.
