For counterpart assistance in cooperation between two schools, it is the prerequisite to take counterpart assistance seriously at the height of building a well off society in an all round way; it is the most needed connecting point to construct the disciplines and teaching staff; it is the most substantial way to develop distant network teaching; it is the fundamental purpose to benefit the students. We will implement the essential of “Program of Counterpart Assistance for Higher Schools in Western China” proposed by Education Ministry in an all round way according to those “Four Aspects”, which have been proved to be the successful measures and developing tendency in the near future for counterpart assistance.

Objective: To investigate effect of continuous plasma filtration adsorption on treatment of severely burned patients with sepsis. Methods: In January 2014 to September 2017, 86 severely burned patients with sepsis, conforming to the study criteria, were admitted to our hospital and divided into into routine treatment group and continuous plasma filtration group according to the random number table method, with 43 patients in each group. Patients in routine treatment group were treated with routine treatment after admission. Patients in continuous plasma filtration group were treated with blood filter, blood purification machine, and plasma separator for continuous plasma filtration adsorption on the basis of the routine treatment group on the second day after admission. The course of treatment in the 2 groups was 7 d. The total effective treatment rate, changes of leukocyte count (WBC), usea nitrogen, serum creatinine, neutrophile CD64, procalcitonin, and C reactive protein (CRP) before and after treatment, and mortality on 28 days after treatment of patients in 2 groups were analyzed and compared. Results: (1) The total effective treatment rate of patients in continuous plasma filtration group was 88.37% (38/43), which was significantly higher than that of the routine treatment group [65.12% (28/43), χ²=6.515, P=0.018]. (2) After treatment, WBC, urea nitrogen, serum creatinine, neutrophils CD64, procalcitonin, and CRP of patients in continuous plasma filtration group were significantly lower those in routine treatment group (t=6.305, 4.420, 18.537, 13.435, 12.975, 14.234, P<0.05). WBC, urea nitrogen, serum creatinine, neutrophile CD64, procalcitonin, and CRP of patients in 2 groups after treatment were significantly lower than those before treatment (t=9.459, 9.130, 25.438, 35.467, 23.471, 23.601, 3.802, 5.662, 12.067, 25.694, 20.720, 12.437, P<0.05). (3) On 28 days after treatment, mortality of patients in continuous plasma filtration group was 6.98% (3/43), which was significantly lower than that in routine treatment group [25.58% (11/43)], χ²=5.460, P=0.023. Conclusions Continuous plasma filtration adsorption is effective in treating severely burned patients with sepsis, which can alleviate inflammatory reaction mediated by inflammatory cytokine with good prognosis.

One severely burned patient, caused by heat lead slag and combined with shock, was hospitalized in our burn unit on 2nd June, 2016. The patient received treatments including anti-shock, intensive care, anti-infection, and organ protection. On post injury day 16, the patient suffered outbreak of acute hemorrhagic necrotizing enteritis after eating dumplings. Plasma and albumin were given, octreotide was intravenously infused to inhibit the secretion of intestinal fluid, the broad-spectrum antibiotics were used for anti-infection, abdominal puncture and drainage were performed, sodium tanshinone ⅡA sulfonate was applied to improve the intestinal microcirculation, ulinastatin was applied to alleviate inflammatory reaction, somatostatin was given to reduce intestinal bleeding, and voriconazole was given for antifungal treatment. The patient gradually recovered and was finally cured and discharged. Among critically ill patients, gastrointestinal tract is not only the initiating organ of sepsis, but also one of the target organs which can be easily damaged during sepsis. This case reminds us the importance of gastrointestinal management in severely burned patients.

Objective:To explore the effect of remote pulmonary rehabilitation management in chronic obstructive pulmonary disease (COPD) patients.Methods:From May 2017 to May 2019, convenience sampling was used to select 114 COPD outpatients in the Respiratory Department of the First Affiliated Hospital of Zhengzhou University. All patients were randomly divided into control group ( n=57) using conventional pulmonary rehabilitation management and observation group ( n=57) using remote pulmonary rehabilitation management, respectively, and the management period was one year. We compared the differences in COPD self-management ability, body mass index, airflow obstruction, dyspnea, exercise capacity (BODE) index, and average annual hospital admission rate between the two groups. Results:After intervention, the scores and the total score of self-management of observation group were higher than those of control group, and the differences were statistically significant ( P<0.01) . The dimension scores and the total score of self-management of observation group after the intervention were higher than those before intervention, and the differences were statistically significant ( P<0.05) . After intervention, the observation group's percentage of forced vital capacity in the first second to predicted value and the 6 minutes walking distance were higher than those of control group, and the dyspnea score and BODE index were lower than those of control group, and the differences were statistically significant ( P<0.05) . The average annual admission rate of the observation group and the control group were 5.41% and 9.06%, respectively. The average annual hospital admission rate of observation group was lower than that of control group, and the difference was statistically significant (χ 2=6.806, P=0.009) . Conclusions:Remote pulmonary rehabilitation management can improve the self-management ability of COPD patients, improve pulmonary function and reduce the admission rate of patients, which is worthy of clinical promotion.

Objective: To investigate the early diagnosis and treatment for burn complicated with severe paroxysmal sympathetic hyperactivity (PSH). Methods: Medical records of patients with burn complicated with severe PSH, admitted to our department from April 2016 to March 2019 and meeting the inclusion criteria were analyzed retrospectively. There were 4 males and 1 female, aged 17 months to 39 years, with an average of (21±16) years. During occurrence of PSH, the vital signs of patients were routinely monitored and oxygen were given. Other treatment included central venous catheterization and infusion of electrolyte solution, infusion of plasma according to patients′ condition, use of opioid analgesics and benzodiazepine sedatives, physical cooling and drug cooling, and establishment or maintenance of artificial airway and use of ventilator. Heart rate was controlled below 120 beats per minute in adults and 140 beats per minute in children with comprehensive treatment dominated by analgesia and sedation. Besides, single or multiple vasoactive agents, even in large doses were used to maintain normal blood pressure of patients. The occurrence characteristics, time, and treatment outcome of PSH were analyzed. Results: PSH happened rapidly, with a sharp increase in several minutes to dozens of minutes. Five patients were with symptoms such as high body temperature, shortness of breath, very fast heart rate, normal or elevated systolic blood pressure, hyperhidrosis, and dystonia at the onset. The symptoms occurred simultaneously or successively. According to the Clinical Feature Scale, the above-mentioned 6 indexes achieved the highest score of 3 points except of systolic blood pressure. Four patients showed dilated pupils and impaired consciousness. Among the patients, PSH occurred in the acute exudation stage in 3 patients, in the fluid reabsorption stage in 1 patient, and in the late repair stage in 1 patient. PSH of patients lasted for 3 hours to 12 days. The symptoms of 4 patients were effectively controlled, and 1 patient died of deterioration. No PSH occurred in the cured patients during follow-up of 3 to 14 months. Conclusions Burn complicated with PSH can occur at any time before wound repair and in patients with different injury conditions. The causes of PSH include sudden burn, persistent pain, fright and fear, strange environment, low blood volume, and other adverse stimuli, and PSH is more likely to occur in children with underdeveloped brain function. Intravenous infusion of analgesics sedatives, physical therapy and medication to lower body temperature, stabilizing blood pressure and respiration are effective measures to treat PSH. PSH should be distinguished from the common complications of burns, such as sepsis, cerebral edema, hyperpyretic convulsion, transfusion response, stress disorder, etc.

On March 14, 2017, a thirty years old male severe burn patient accompanied by asphyxia, sudden cardiac arrest, and acute respiratory distress syndrome was admitted to Zhengzhou First People′s Hospital. During the shock stage, the pulse contour cardiac output was monitored for the restrictive rehydration, tracheotomy was performed, and fibrobronchoscope lavage was performed for the treatment of inhalation injury and pulmonary infection. An alternate application of suspended bed and turning bed was conducted to balance the treatment of cerebral edema and pulmonary infection; targeted antibiotics were used for anti-infective treatment; multiple operations were performed for eschar excision and skin grafting. At last, the wounds were all healed, the lung infection was cured, and the patient was discharged with severe disturbance of consciousness. Asphyxia and acute respiratory distress syndrome post-cardiopulmonary resuscitation are serious complications in severe burn patients. The clinical treatment of such patients is very difficult and should be highly alerted.

Objective:To investigate the clinical characteristics and risk factors of critical burn patients complicated with invasive fungal infection.Methods:A retrospective case series study was conducted. From January 2017 to December 2022, 88 critical burn patients combined with invasive fungal infection who met the inclusion criteria were admitted to Zhengzhou First People's Hospital, including 61 males and 27 females, aged 26-74 years. Data on invasive fungal infection sites and the detection of pathogens in patients were recorded. According to the survival outcome within 28 days after admission, the patients were divided into survival group (63 cases) and death group (25 cases). The following data of patients were compared between the two groups, including the basic data and injuries of patients at admission such as age, sex, body weight, total burn area, combination of inhalation injury, combination of hypertension and diabetes, acute physiology and chronic health status evaluation Ⅱ (APACHE Ⅱ) score, and admission time after burns, the levels of blood biochemical indexes within 24 h after admission such as white blood cell count, platelet count, red blood cell count, monocyte count, neutrophil count, lymphocyte count, alanine transaminase, aspartate transaminase, glucose, creatinine, urea nitrogen, D-dimer, galactomannan (GM), 1,3-β-D glucan, and creatine kinase, the application of invasive procedures and vasoactive drugs during the treatment such as continuous renal replacement therapy, ventilator-assisted breathing, tracheotomy, deep vein catheterization, skin grafting >2 times, the levels of infection indicators on post admission day (PAD) 1, 3, 7, and 14 including C-reactive protein (CRP), procalcitonin, lactic acid, interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α), and the detection of pathogens in the process of treatment. Data were statistically analyzed with independent sample t test, analysis of variance for repeated measurement, chi-square test, Mann-Whitney U test, and Bonferroni correction. Multivariate logistic regression analysis was performed to screen the independent risk factors that affected death of critical burn patients complicated with invasive fungal infection. Results:The main sites of invasive fungal infection were the wounds (67 cases) and blood stream (46 cases), with Candida fungi (58 strains) as the main strain for fungi infection, and there were a total of 30 cases of infection with mixed pathogenic bacteria. Compared with those in survival group, the APACHE Ⅱ score, proportions of combination with inhalation injury and hypertension of patients in death group were significantly increased ( t=2.11, with χ2 values of 6.26 and 9.48, respectively, P<0.05), while the other basic data and injury condition had no significant changes ( P>0.05). Compared with those in survival group, the levels of D-dimer, GM, and 1,3-β-D glucan of patients in death group were significantly increased within 24 h after admission (with t values of 2.42, 2.05, and 2.21, respectively, P<0.05), while the other blood biochemical indexes within 24 h after admission, as well as the proportions of applying invasive procedures and application of vasoactive drugs during the treatment process were not significantly changed ( P>0.05). The levels of infection indicators of patients on PAD 1 and 3 were similar between the two groups ( P>0.05). The procalcitonin level on PAD 7 and the levels of CRP, procalcitonin, lactic acid, IL-6, and TNF-α on PAD 14, as well as the proportion of infection with mixed pathogenic bacteria of patients in death group were significantly higher than those in survival group (with t values of 4.69, 3.89, 6.70, 6.14, 4.65, and 3.26, respectively, χ2=12.67, P<0.05). Multivariate logistic regression analysis showed that combination with inhalation injury, combination with hypertension, and infection with mixed pathogenic bacteria were independent risk factors for death of critical burn patients complicated with invasive fungal infection (with odds ratios of 5.98, 4.67, and 6.19, respectively, 95% confidence intervals of 1.42-15.39, 1.41-25.28, and 1.86-20.58, respectively, P<0.05). Conclusions:The main sites of infection in critical burn patients complicated with invasive fungal infection are the wounds and blood stream, with Candida fungi as the main strain for fungi infection, and a large proportion of infection with mixed pathogenic bacteria. The combined inhalation injury, combined hypertension, and infection with mixed pathogenic bacteria are the independent risk factors for the death of those patients.

Objective To investigate the safety and efficacy of camrelizumab added to second-line therapy after drug- eluting bead transarterial chemoembolization (DTACE) combined with apatinib for unresectable hepatocellular carcinoma (HCC). Methods A retrospective analysis was performed for 89 HCC patients with camrelizumab added to second-line therapy who attended The First Affiliated Hospital of Zhengzhou University from December 2019 to December 2020. The primary endpoints were overall survival (OS) and progression-free survival (PFS) after the application of camrelizumab, and the secondary endpoints were objective remission rate (ORR), disease control rate (DCR), and treatment-related adverse events (TRAEs). The Kaplan-Meier method was used to plot survival curves, the Log-rank test was used for stratified analysis of subgroups based on baseline characteristics, and the influencing factors for prognosis were analyzed. Results A total of 89 patients were screened and followed up in this study. The patients were followed up to December 2021, with a median follow-up time of 16 months, a median OS time of 17.0 (95% confidence interval [ CI ]: 15.3-18.7) months, and a median PFS time of 7.0 (95% CI : 6.2-7.8) months. There were significant differences in OS and PFS between the patients with different ECOG-PS scores, liver function Child-Pugh classes, portal vein invasion, patterns of progression, times of DTACE treatment, durations of oral administration of apatinib, and durations of application of camrelizumab (all P < 0.05). At 3 and 6 months after the application of camrelizumab, ORR was 39.3% and 22.4%, respectively, and DCR was 80.9% and 54.1%, respectively. The univariate analysis using the Log-rank test showed that compared with the patients receiving 0 time of DTACE treatment, the patients receiving 3-4 or 1-2 times of DTACE treatment had significant improvements in median OS [22.0 (95% CI : 21.1-22.9) months and 17.0 (95% CI : 15.8-18.2) months vs 10.0 (95% CI : 7.0-13.0) months, χ 2 =31.423, P < 0.001] and PFS [10.0 (95% CI : 7.0-13.0) months and 7.0 (95% CI : 6.2-7.8) months vs 3.0 (95% CI : 1.9-4.1) months, χ 2 =20.741, P < 0.001]; compared with the patients using apatinib for ≤4 months, the patients using apatinib for > 4 months had significant improvements in median OS [21.0 (95% CI : 19.1-22.9) months vs 14.0 (95% CI : 10.4-17.6) months, χ 2 =19.399, P < 0.001] and PFS [9.0 (95% CI : 7.3-10.7) months vs 5.0 (95% CI : 4.0-6.0) months, χ 2 =27.733, P < 0.001]; compared with the patients using camrelizumab for ≤5 months, the patients using camrelizumab for > 5 months had significant improvements in median OS [22.0 (95% CI : 20.2-23.8) months vs 13.0 (95% CI : 9.3-16.7) months, χ 2 =22.336, P < 0.001] and PFS [9.0 (95% CI : 7.0-11.0) months vs 5.0 (95% CI : 4.1-5.9) months, χ 2 =26.141, P < 0.001]. Post-embolization syndrome was the adverse event after DTACE and resolved after symptomatic treatment. Adverse reactions related to targeted drugs and immunotherapy all resolved after symptomatic supportive treatment, with no grade ≥4 adverse reactions, and no patients withdrew from target-free therapy due to TRAEs. Conclusion As for DTACE combined with apatinib in the treatment of unresectable HCC, camrelizumab added after progression has a marked therapeutic efficacy with safe and controllable TRAEs.
