Results:Effectively, the management of fixed assets was lead to a virtuous cycle. Conclusion: In the management process, economic benefits management, performance and quality management and evaluation should be different among different kinds of fixed assets. Thus, the hospital managers should focus and treat them differently, in order to achieve better or more effective management.

Objective To explore the safety and applicability of a temporary protective ileostomy that closes itself in the prevention of anastomotic leakage following anterior resection after chemoradiation for rectal cancer.Methods From Oct 2010 to Oct 2013,54 cases of middle or low rectal carcinoma were admitted.Protective ileostomy was created to prevent anastomotic leakage.Patients were divided into two groups receiving respectively intubation ileostomy (group A,28 cases),and conventional ileostomy (group B,26 cases).Results The mean time for anus to restore defecation was identical in the two groups.The period of protection of the anastomosis,was 21 d (15 ～ 35 d) in group A.The rate of spontaneous closure of the stoma after removal of the tube was 100％.The stoma was reduced after 3 to 6 months in group B and major complication developed in one case in this group.Conclusions Temporary ileostomy prevents anastomotic leakage of anterior resection in patients of rectal carcinoma receiving preoperative neoadjuvant chemoradiotherapy.Intubation ileostomy is effective and safe in prevention of anastomotic leakage saving stoma reduction procedures.

Objective To compare the effect of three kinds of reverse trendelenburg position angle in block plane of prone position after subarachnoid anesthesia, in order to acquire the conformable reverse trendelenburg position angle of prolapse and hemorrhoids (PPH). Methods Sixty patients having underwent the selective PPH were divided into 10° group, 20° group and 30° group by random digits table method with 20 cases each. Subarachnoid puncture was performed in the L3 - 4 processus spinosus gap, then 0.5%heavy density ropivacaine 2 ml was injected. After anesthesia, the operation bed was adjusted to reverse trendelenburg position 10° (10° group), 20° (20° group) and 30° (30° group). At the same time the patients changed to prone position, and the operation bed was changed to horizontal position before operation. The patients changed to jackknife position 10 min after drug injection of subarachnoid anesthesia. The sensory blockade after drug infusion, circulation function change, anesthetic effect and perioperative adverse reaction were observed. Results There were no statistical differences in operation start time and fixed time of anesthesia plane among 3 groups (P>0.05). The upper bound of sensory nerve block before horizontal position, upper bound of sensory nerve block before jackknife position, highest plane of sensory nerve block in 10° group were significantly higher than those in 20° group and 30° group: T(10.47 ± 0.65) vs. T(12.36 ± 0.72) and T(12.50 ± 0.54), T(10.12 ± 0.56) vs. T(11.82 ± 0.66) and T(11.99 ± 0.72), T(9.53 ± 0.71) vs. T(11.32 ± 0.78) and T(11.54 ± 0.83), and there were statistical differences (P<0.05); but there were no statistical difference between 20° group and 30° group (P>0.05). The systolic blood pressure and diastolic blood pressure levels 15 and 20 min after drug infusion in 10° group were significantly lower than those in 20° group and 30° group, systolic blood pressure:(120.40 ± 7.38) mmHg (1 mmHg=0.133 kPa) vs. (131.82 ± 7.88) and (130.47 ± 7.57) mmHg, (119.55 ± 7.65) mmHg vs. (131.25 ± 9.67) and (130.23 ± 8.69) mmHg, diastolic blood pressure: (63.74 ± 6.54) mmHg vs. (71.36 ± 8.49) and (74.32 ± 7.54) mmHg, (61.59 ± 6.23) mmHg vs. (72.98 ± 7.39) and (73.75 ± 6.34) mmHg, and there were statistical differences (P<0.05);but there were no statistical difference between 20° group and 30° group (P>0.05). No patients′ anesthesia effect was poor in 3 groups, but 4 cases in 30° group were good. Hypotension and tachycardia occurred in 2 cases in 10° group, respectively. Conclusions Immediately prone position after subarachnoid anesthesia can be adjusted by reverse trendelenburg position angle to get the appropriate level of anesthesia, and conformable reverse trendelenburg position angle of PPH is 20°.

OBJECTIVETo investigate the effects of lung protective ventilation strategy combined with lung recruitment maneuver on ARDS complicating patients with severe burn.

METHODSClinical data of 15 severely burned patients with ARDS admitted to our burn ICU from September 2011 to September 2013 and conforming to the study criteria were analyzed. Right after the diagnosis of acute lung injury/ARDS, patients received mechanical ventilation with lung protective ventilation strategy. When the oxygenation index (OI) was below or equal to 200 mmHg (1 mmHg = 0. 133 kPa), lung recruitment maneuver was performed combining incremental positive end-expiratory pressure. When OI was above 200 mmHg, lung recruitment maneuver was stopped and ventilation with lung protective ventilation strategy was continued. When OI was above 300 mmHg, mechanical ventilation was stopped. Before combining lung recruitment maneuver, 24 h after combining lung recruitment maneuver, and at the end of combining lung recruitment maneuver, variables of blood gas analysis (pH, PaO2, and PaCO2) were obtained by blood gas analyzer, and the OI values were calculated; hemodynamic parameters including heart rate, mean arterial pressure (MAP), central venous pressure (CVP) of all patients and the cardiac output (CO), extravascular lung water index (EVLWI) of 4 patients who received pulse contour cardiac output (PiCCO) monitoring were monitored. Treatment measures and outcome of patients were recorded. Data were processed with analysis of variance of repeated measurement of a single group and LSD test.

RESULTS(1) Before combining lung recruitment maneuver, 24 h after combining lung recruitment maneuver, and at the end of combining lung recruitment maneuver, the levels of PaO2 and OI of patients were respectively (77 ± 8), (113 ± 5), (142 ± 6) mmHg, and (128 ± 12), (188 ± 8), (237 ± 10) mmHg. As a whole, levels of PaO2 and OI changed significantly at different time points (with F values respectively 860. 96 and 842. 09, P values below 0. 01); levels of pH and PaCO2 showed no obvious changes (with F values respectively 0.35 and 3.13, P values above 0.05). (2) Levels of heart rate, MAP, CVP of all patients and CO of 4 patients who received PiCCO monitoring showed no significant changes at different time points (with F values from 0. 13 to 4. 26, P values above 0.05). Before combining lung recruitment maneuver, 24 h after combining lung recruitment maneuver, and at the end of combining lung recruitment maneuver, the EVLWI values of 4 patients who received PiCCO monitoring were respectively (13.5 ± 1.3), (10.2 ± 1.0), (7.0 ± 0.8) mL/kg ( F =117.00, P <0.01). (3) The patients received mechanical ventilation at 2 to 72 h after burn, lasting for 14-32 (21 ± 13) d. At post injury day 3-14 (7 ± 5) d, lung recruitment maneuver was applied for 2-5 (3.0 ± 2.0) d. All 15 patients recovered without other complications.

CONCLUSIONSLung protective ventilation strategy combining lung recruitment maneuver can significantly improve the oxygenation in patients with severe burn complicated with ARDS and may therefore improve the prognosis.

Objective: To explore the effects of silencing Smad ubiquitination regulatory factor 2 (Smurf2) on the secretion of transforming growth factor beta 1 (TGF-β₁), alpha-smooth muscle actin (α-SMA), and collagen type Ⅰ by human hypertrophic scar-derived fibroblasts. Methods: The human normal skin-derived fibroblasts and hypertrophic scar-derived fibroblasts were cultured with explant culture technique from the normal skin and hypertrophic scar tissue, which was obtained from 9 patients with hypertrophic scars after burn. Two kinds of fibroblasts of the third passage were both divided into 6 groups according to the random number table, with 9 wells in each group. Fibroblasts in blank control group were cultured for 72 h without transfection of any small interfering RNA (siRNA), fibroblasts in negative control group were for cultured for 72 h after transfected with non-target siRNA, fibroblasts in Smurf2 siRNA group were cultured for 72 h after transfected with 100 nmol/L Smurf2 siRNA, fibroblasts in blank control+ TGF-β₁ group were cultured for 72 h without transfection of any siRNA and then treated with 10 ng/mL TGF-β₁ for 6 h, fibroblasts in negative control+ TGF-β₁ group were cultured for 72 h after transfected with non-target siRNA and then treated with 10 ng/mL TGF-β₁ for 6 h, fibroblasts in Smurf2 siRNA+ TGF-β₁ group were cultured for 72 h after transfected with Smurf2 siRNA and then treated with 10 ng/mL TGF-β₁ for 6 h.

Data were processed with analysis of variance of factorial design and Bonferroni test. Results: (1) The protein and mRNA expression levels of Smurf2 of the two kinds of cells in Smurf2 siRNA group were significantly lower than those in blank control group and negative control group (with P values below 0.05). The protein and mRNA expression levels of Smurf2 of the two kinds of cells in blank control group and negative control group were close (with P values above 0.05). (2) The content of TGF-β₁ in the cell culture supernatant of hypertrophic scar-derived fibroblasts in blank control group and Smurf2 siRNA group was respectively (4.34±0.56) and (2.14±0.28) pg/mL, which was significantly higher than (1.52±0.20) and (1.41±0.18) pg/mL of normal skin-derived fibroblasts respectively (with P values below 0.05). In hypertrophic scar-derived fibroblasts, the content of TGF-β₁ in the cell culture supernatant in Smurf2 siRNA group was significantly lower than that in blank control group (P<0.05). In normal skin-derived fibroblasts, the content of TGF-β₁ in the cell culture supernatant in Smurf2 siRNA group was close to that in blank control group (P>0.05). (3) The protein expression levels of α-SMA and content of collagen type Ⅰ in the cell culture supernatant of the two kinds of cells in blank control+ TGF-β₁ group were significantly higher than those in blank control group (with P values below 0.05). The protein expression levels of α-SMA and content of collagen type Ⅰ in the cell culture supernatant of the two kinds of cells in negative control+ TGF-β₁ group were significantly higher than those in negative control group (with P values below 0.05). The protein expression levels of α-SMA and content of collagen type Ⅰ in the cell culture supernatant of the two kinds of cells in Smurf2 siRNA group were close to those in blank control group and negative control group (with P values above 0.05). The protein expression levels of α-SMA and content of collagen type Ⅰ in the cell culture supernatant of the two kinds of cells in Smurf2 siRNA+ TGF-β₁ group were significantly lower than those in blank control+ TGF-β₁ group and negative control+ TGF-β₁ group (with P values below 0.05). (4) The mRNA expression levels of α-SMA and collagen type Ⅰ of the two kinds of cells in blank control+ TGF-β₁ group were significantly higher than those in blank control group (with P values below 0.05). The mRNA expression levels of α-SMA and collagen type Ⅰ of the two kinds of cells in negative control+ TGF-β₁ group were significantly higher than those in negative control group (with P values below 0.05). The mRNA expression levels of α-SMA and collagen type Ⅰ of the two kinds of cells in Smurf2 siRNA group were close to those in blank control group and negative control group (with P values above 0.05). The mRNA expression levels of α-SMA and collagen type Ⅰ of the two kinds of cells in Smurf2 siRNA+ TGF-β₁ group were significantly lower than those in blank control+ TGF-β₁ group and negative control+ TGF-β₁ group (with P values below 0.05). Conclusions Silencing Smurf2 in human hypertrophic scar-derived fibroblasts can reduce the autocrine of TGF-β₁ and inhibit the TGF-β₁-induced α-SMA expression and collagen type Ⅰ synthesis.

Objective: To investigate the effect and regulatory mechanism of Smurf2 on the negative regulator Smad7 of TGF-β1/Smad signaling pathway in hypertrophic scar fibroblasts. Methods: From January to October 2014, 8 patients with hypertrophic scar after burn were admitted. The age of patients ranged from 1 year 8 months to 7 years, and the time of scar hyperplasia ranged from 2 to 12 months. The residual normal skin of the same patient was used as the control. The fibroblasts were isolated from hypertrophic scar and normal skin respectively and cultured. The third to fifth passage cells were used for the experiments. ① The protein expression of Smad7 in the two groups was detected by Western Blot. ② Hypertrophic scar fibroblasts and normal skin fibroblasts were treated with exogenous TGF-β1 at concentration of 10 ng/ml for 0 min, 5 min, 15 min, 30 min, 1 h, 2 h and 12 h. The expression of Smad7 protein and mRNA were detected by Western Blot and RT-PCR, respectively. ③ The cell lysates of the two groups were collected and incubated with the ubiquitin mixture for 1 h, 2 h and 6 h at 37℃, respectively. The degradation level of Smad7 protein was detected by Western Blot. ④ The cell lysate of hypertrophic scar fibroblasts was collected and incubated with ubiquitin mixture with or without proteasome inhibitor (MG132: MG115=1: 1) to study its inhibitory effect on the degradation of Smad7 in vitro. ⑤ Immunoprecipitation (IP) technique was used to detect the interaction between Smad 7 and E3 ubiquitin ligase Smurf2 in hypertrophic scar fibroblasts. ⑥ The expression of Smad7 protein in hypertrophic scar fibroblasts stimulated by TGF-β1 after Smurf2 silencing by small interference RNA (siRNA) technique were detected by Western blot. Results: ① There was no significant difference in the expression level of Smad7 protein between hypertrophic scar and normal skin fibroblasts(t=0.76, P=0.46). ② Expressions of Smad7 mRNA and protein in normal skin fibroblasts stimulated by exogenous TGF-β1 gradually increased in a time-dependent manner(P<0.05). The expression of Smad7 mRNA in the hypertrophic scar fibroblasts increased at all-time points except at 5min , (P<0.05), while there was no significant difference in the expression level of Smad7 protein at all-time points with or without TGF-β1 stimulation(P>0.05). ③ Degradation of Smad7 protein was enhanced in hypertrophic scar fibroblasts (the expression level of Smad 7 protein at each time point was compared with that of the control group and the last time point, P<0.05), while there was no significant difference in Smad7 protein degradation in normal skin fibroblasts(P=0.162). ④ Enhanced degradation of Smad7 in hypertrophic scar fibroblasts was blocked by the addition of the proteasome inhibitors MG132/MG115. ⑤ In hypertrophic scar fibroblasts, the Smurf2-Smad7 complex was detected, which indicated the interaction between Smurf2 and Smad7 in hypertrophic scar fibroblasts. ⑥ The expression of Smad7 protein was not increased in the hypertrophic scar fibroblasts stimulated by TGF-β1, whereas the stimulation of TGF-β1 increased the expression of Smad7 protein after silencing of Smurf2 gene expression. Conclusions In the hypertrophic scar fibroblasts, Smurf 2 attenuates the inhibitory effect of Smad 7 on TGF-β1 signaling pathway through the degradation of Smad7 by ubiquitination, which may be involved in the formation of hypertrophic scar.

OBJECTIVETo analyze the detection, drug resistance, and status of infection of Acinetobacter baumannii (AB) in burn ICU during 3 years.

METHODSA total of 2 010 specimens of wound secretion, blood, venous catheter attachment, sputum, stool and urine were collected from 505 burn patients hospitalized in our burn ICU from January 2011 to December 2013, and bacterial culture was performed. Pathogens were identified by automatic microorganism identifying and drug sensitivity analyzer. Drug resistance of all the obtained AB to 16 antibiotics commonly used in clinic, including cefoperazone/sulbactam, polymyxin, etc., was tested with K-B paper disk diffusion method. Patients with AB infection were ascertained. The WHONET 5.6 software was used to analyze the distribution of pathogens during 3 years, the isolation of AB with different sources and the status of drug resistance of AB to 16 antibiotics each year, and the status of patients with AB infection, and their outcome.

RESULTSA total of 961 strains of pathogens were isolated, among which 185 (19.25%) strains were Gram positive cocci, 728 (75.75%) strains were Gram negative bacilli, and 48 (4.99%) strains were fungi. A total of 172 strains of AB were isolated, ranking the second place among all the detected pathogens, with 67 (38.95%) strains from wound secretion, 11 (6.40%) strains from blood, 23 (13.37%) strains from venous catheter attachment, and 71 (41.28%) strains from sputum, no AB strain was isolated from feces or urine. The AB strains were found sensitive to polymyxin and with relatively low drug resistance rate to minocycline, while the drug resistance rates were over 80.0% to the other 14 antibiotics commonly used in clinic in 2013. AB culture of wound secretion was positive in 27 patients. Among them, 7 patients suffered from wound infection, and the wound infection was caused by AB in 1 out of the 7 patients. AB culture of blood was positive in 7 patients. Among them, 3 patients suffered from bloodstream infection, and the infection was due to AB invasion in 1 out of the 3 patients. AB culture of venous catheter attachment was positive in 20 patients. Among them, 8 patients suffered from bloodstream infection, and the infection was due to AB invasion in 1 out of the 8 patients. AB culture of sputum was positive in 35 patients. Among them, 13 patients suffered from ventilatory associated pneumonia, and 2 out of the 13 patients were diagnosed as AB infection. A total of 69 patients were AB culture positive, among them 64 patients were cured, 2 patients were transferred to other hospitals, and 3 patients died, with the mortality rate of 4.35%.

CONCLUSIONSAB in our burn ICU has a high detection rate and extensive drug resistance in above-mentioned 3 years. However, AB was mainly colonized in patients with extensive burns with a low mortality rate.

OBJECTIVETo investigate the effects of unified surgical scheme for wounds on the outcome of patients with extensive deep partial-thickness to full-thickness (briefly referred to as deep) burn.

METHODSOne hundred and thirty-seven patients with extensive deep burn hospitalized from July 2007 to November 2012 underwent unified surgery according to area of deep wound (unified scheme group, US). Among them, 57 patients with deep wound area less than 51% TBSA received escharectomy or tangential excision by stages followed by autologous mesh skin grafting; 52 patients with deep wound area from 51% to 80% TBSA underwent escharectomy or tangential excision by stages followed by autologous mesh skin grafting and/or small skin grafting, or escharectomy or tangential excision followed by large sheet of allogeneic skin covering plus autologous mesh skin grafting and/or small skin grafting after the removal of allogeneic skin; 28 patients with deep wound area larger than 80% TBSA received escharectomy or tangential excision by stages followed by autologous microskin grafting plus coverage of large sheet of allogeneic skin, or escharectomy or tangential excision followed by small autologous skin grafting and/or intermingled grafting with small autologous and/or allogeneic skin. Another 120 patients with extensive deep burn hospitalized from January 2002 to June 2007 who did not receive unified surgical scheme were included as control group (C). Except for the surgical methods in group US, in 53 patients with deep wound area less than 51% TBSA in group C escharectomy or tangential excision was performed followed by autologous small skin grafting; in 40 patients with deep wound area from 51% to 80% TBSA in group C escharectomy or tangential excision was performed followed by autologous microskin grafting plus large sheet of allogeneic skin covering, or escharectomy or tangential excision followed by large sheet of allogeneic skin embedded with stamp-like autologous skin; in 27 patients with deep wound area larger than 80% TBSA in group C escharectomy or tangential excision was performed followed by covering with large sheet of allogeneic skin embedded with stamp-like autologous skin without intermingled grafting with small autologous and allogeneic skin in group US. In group US, escharectomy of full-thickness wound in extremities was performed with the use of tourniquet in every patient; saline containing adrenaline was subcutaneously injected when performing escharectomy or tangential excision over the trunk and skin excision; normal skin and healed superficial-thickness wound were used as donor sites for several times of skin excision. The baseline condition of patients and their treatment in the aspects of fluid resuscitation, nutrition support, anti-inflammation, and organ function support were similar between the two groups. The mortality and incidence of complications of all patients and wound healing time and times of surgery of healed patients were compared between the two groups. Data were processed with independent sample t test, Mann-Whitney U test, and Fisher's exact test.

RESULTS(1) Both the mortality and the incidence of complications of patients with deep wound area less than 51% TBSA in group US were 0, which were close to those of group C (with P values above 0.05). The number of times of surgery of healed patients with deep wound area less than 51% TBSA in group US was 2.4 ± 0.9, which was obviously fewer than that of group C (3.5 ± 1.8, U=-5.085, P<0.001), but with wound healing time close to that of group C (U=-1.480, P>0.05). (2) Both the mortality and the incidence of complications of patients with deep wound area from 51% to 80% TBSA in group US were 0, which were significantly lower than those of group C [both as 20.0% (8/40), with P values below 0.01]. The number of times of surgery and wound healing time of healed patients with deep wound area from 51% to 80% TBSA in group US were respectively 3.0 ± 1.0 and (43 ± 13) d, which were obviously fewer or shorter than those in group C [4.2 ± 2.3 and (61 ± 34) d, with U values respectively -2.491 and -2.186, P values below 0.05]. (3) Both the mortality and the incidence of complications of patients with deep wound area larger than 80% TBSA in group US were 25.0% (7/28), which were close to those of group C [both as 25.9% (7/27), with P values above 0.05]. The number of times of surgery and wound healing time of healed patients with deep wound area larger than 80% TBSA in group US were close to those of group C (with U values respectively -0.276 and -0.369, P values above 0.05).

CONCLUSIONSUnified surgical scheme can indirectly decrease the mortality and the incidence of complications of burn patients with deep wound area from 51% to 80% TBSA; it can reduce times of surgery of healed patients of this type and shorten their wound healing time.

Objective: To analyze the causes of complication of early acute kidney injury (AKI) in four severely burned patients, and to explore the related treatment methods. Methods: The clinical data of 4 patients with severe burn complicated with early AKI admitted to Guangzhou Red Cross Hospital Affiliated to Medical College of Jinan University (hereinafter referred to as our hospital) from June 2014 to December 2017 were retrospectively analyzed. All the patients were male, aged 23-33 (30±5) years old, with depth of burns ranged from deep partial-thickness to full-thickness, complicated with myofascial compartment syndrome of extremities and varying degrees of striated muscle injury, and treated in other hospitals before transfer to our hospital. The patients were numbered from small to large according to the total burn area. The total burn area of patients No. 1, 2, 3, and 4 was 10%, 80%, 90%, and 95% total body surface area respectively, their occurrence time of early AKI was 48, 11, 29, and 48 hours after injury respectively, and their time of arriving our hospital was 60, 11, 29, and 144 hours after injury respectively. Hypovolemic shock occurred in patients No. 2 and 3 at admission to our hospital. All the patients received continuous renal replacement therapy (CRRT) after admission to our hospital. Under the support of hemodynamic monitoring and organ function monitoring, the limbs complicated with myofascial compartment syndrome were incised, thorough decompression exploration was performed, and necrotic muscle tissue was removed or amputation was performed. After escharectomy and decompression of limbs, fresh granulation wounds were formed by temporarily covering wounds with Jieya dressing skin or pig skin, multiple debridements, and vacuum sealing drainage. Fresh granulation wounds and other wounds underwent staged eschar excision and shaving were covered with autologous Meek skin graft, particulate skin graft, reticular skin graft and small skin graft respectively. The treatment outcome, CRRT time, operation times, time of recovery of serum creatinine and myoglobin, length of hospital stay, and follow-up were recorded. Results: All the 4 patients were cured after transfer to our hospital. Among them, totally 5 limbs of patients No. 1 and No. 4 underwent amputation because of complication of myofascial compartment syndrome and a large amount of necrotic muscle which could not be preserved. Patients No. 1, 2, 3, and 4 were treated with CRRT for 19, 35, 14, and 25 days respectively and performed with operation for 5, 6, 10, 8 times respectively. Serum creatinine of patients No. 1, 2, 3, and 4 returned to normal on 22, 35, 37, and 48 days after transfer respectively, and their serum myoglobin returned to normal on 18, 28, 25, and 30 days after transfer respectively. Patients No. 1, 2, 3, and 4 were hospitalized for 52, 105, 148, and 156 days and discharged after basic wound healing. Follow-up for 1 to 36 months showed no abnormal renal function in 4 patients. Conclusions The early AKI in patients No. 1 and 4 was caused by rhabdomyolysis after severe burn complicated with myofascial compartment syndrome, while that of the other 2 cases were also related to hypovolemic shock and poor renal perfusion. The success rate of early AKI treatment in severely burned patients can be effectively improved by removing the causes of diseases at the same time of CRRT and actively treating burn wounds under the support of organ function and hemodynamic monitoring.
