Objective To investigate the pathogenesis of acute lung injury in rats induced by intra-peritoneally injection of perforative peritonitis ascitic fluids（PPAF） and the role of L-arginine （L-Arg） in acute lung injury in this model. Methods Perforative peritonitis （PP） models were established in 60 rats and PPAF were collected. Forty-eight rats were randomly divided equally into NS group，PPAF group, and L-Arg group. Rats were randomly subjected to death at 7 h and 12 h. Peripheral blood WBC were counted，levels of NO and malondialdehyde （MDA） in serum were examined. Lung injury score and wet/dry ratio were evaluated， and level of myeloperoxidase （MPO） in lung tissues and lung cell apoptosis were tested. Results WBC count of peripheral blood, levels of NO and MDA in serum， level of MPO in lung tissue, lung injury score， wet/dry ratio， and lung cell apoptosis rate in PPAF group were significantly higher than that in NS group at each time point（P＜0.01）. Level of NO in serum in L-Arg group was higher than that in PPAF group （P＜0.01）， but lower level of MDA in serum， lower level of MPO in lung tissue and lung injury score，lower wet/dry ratio， and lung cell apoptosis rate were observed in L-Arg group（P＜0.05）. In PPAF group and L-Arg group， level of NO in serum， wet/dry ratio, and lung cell apoptosis rate were higher at 12 h than that at 7 h（P=0.000）. Serum NO level was in negative correlation with serum MDA level （r=-0.257，P=0.021）， MPO level in lung tissue（r=-0.444， P=0.011），and lung cell apoptosis（r=-0.351， P =0.010） in PPAF group and L-Arg group， but serum MDA level was in positive correlation with cell apoptosis（r=0.969， P＜0.001） in each group. Conclusions Acute lung injury rats model can be established by intra-peritoneally injection of PPAF. Enhanced oxidizing reaction and cell apoptosis take part in the occurrence of acute lung injury. L-Arg plays a protective role in acute lung injury.
Objective To study the effects of different carbon dioxide pneumoperitoneum pressure and time on abdominal cavity infection bacteria of peritonitis in rats, including bacteria growth and bacterial translocation. Methods Sixty Sprague Dawley rats were injected with Eseherichia coli into the abdominal cavity to establish models of intra-abdominal infection. To give 3 types of pneumoperitoneum pressure for the experimental group: 15 mm Hg (1 mm Hg=0.133 kPa) for high pressure group, 5 mm Hg for low pressure group, and blank control group for no-pneumoperitoneum. To give 2 types of experimental period: 1 h and 3 h. These 60 Sprague Dawley rats were randomly divided intomoperi 6 groups by random number table. They were treated by different pneumoperitoneum pressure and time. All rats were killed at the end of the carbon-dioxide pneumo-peritoneum experiment. Peritoneal lavage fluids and portal vein blood were taken for microbiological examinations and culture. The endotoxin content in portal vein blood was detected too. Results ① Bacteria content: bacteria counts of different pneumoperitoneum pressure groups were obviously different (F=9.02, P=0.020), bacteria counts of different experimental period groups were obviously different (F=8.47, P=0.003), the effect of time was different in different pneumoperitoneum pressure groups (F=8.07, P=0.020). ② Bacterial translocation: Bacterial translocation occurred in all 6 groups. Blood culture positive rates were similar between 1 h group and 3 h group at 3 types of pneumoperitoneum pressure groups (P>0.05). The positive rate of blood culture in high pneumoperitoneum group was significantly higher compared with the no-pneumoperitoneum group (P<0.05). ③ The endotoxin content: the endotoxin content of different pneumoperitoneum pressure groups were obviously different (F=14.70, P<0.01), the endotoxin content in plasma increased obviously in high pressure group compared with low pressure group (P=0.018) and no-pneumoperitoneum group (P<0.01), the endotoxin content in plasma increased obviously in low pressure group compared with no-pneumoperitoneum group (P=0.005). The endotoxin content of different experimental period groups were obviously different (F=148.90, P<0.01), the endotoxin content in plasma increased obviously in 3 h group compared with 1 h group. There were no significant difference in the effect of time with different pneumoperitoneum pressure groups (F=0.14, P=0.874). Conclusion CO2pneumoperitoneum promoted intestinal bacterial endotoxin and bacterial translocation in peritonitis of rats, which increased with the pressure and time.

ObjectiveTo investigate the clinical characteristics, treatment and outcomes of patients with Acinetobacter baumannii peritoneal dialysis-related peritonitis.MethodsWe retrospectively analyzed the clinical data of patients with Acinetobacter baumannii peritoneal dialysis-related peritonitis in the First Affiliated Hospital of Airforce Military University from January 2011 to December 2018. The clinical baseline data, treatment process, microbiological data, antibiotic susceptibility test of the bacterial isolates and outcomes were analyzed.ResultsA total of 10 patients were enrolled, including 4 males and 6 females. The average age of all patients was (44.90±17.03) years, the average age of peritoneal dialysis was (21.70±17.06) months. Seven cases were infected for the first time, and 3 cases were reinfected. The infections were mainly caused by mechanical failure of catheter connection system (3 cases) or enterogenous infection (3 cases). The main symptoms were abdominal pain (10 cases), fever (7 cases) and diarrhea (3 cases). Empirical anti-infective treatment was given after admission, only 1 case was effective, and the treatment of the other 9 cases were adjusted according to the results of drug sensitivity. Acinetobacter baumannii was sensitive to cefoperazone, carbapenem (meropenem, imipenem), quinolones (ciprofloxacin, levofloxacin), aminoglycosides (gentamicin) and polymyxin. Only one case was resistant to ceftazidime. Among the 10 patients, 8 cases were cured (continued peritoneal dialysis), 1 case died, and 1 case dropped out from peritoneal dialysis to hemodialysis.ConclusionsAcinetobacter baumannii peritoneal dialysis-related peritonitis in this hospital is mainly caused by mechanical disturbance of catheter connection system or enterogenic infection. Appropriate measures, including aseptic standard operation, follow-up and effective anti-infective treatment, should be taken to decrease the incidence and mortality of Acinetobacter baumannii peritoneal dialysis-related peritonitis.
ObjectiveTo investigate the diagnosis and treatment value of multi-disciplinary team (MDT) model in patient with gastric perforation combined with hyperthyroidism crisis.MethodWe summarized the experiences of MDT model in treating one case of gastric perforation with hyperthyroidism crisis in the Fuling Central Hospital of Chongqing City on February 2019.ResultsThis patient had a history of hyperthyroidism and didn’t receive systemic treatment, diagnosing as acute diffuse peritonitis and perforation of hollow organs. After MDT discussions and a series of treatments, including anti-infection, control of heart rate and hyperthyroidism, this patient underwent surgical treatment of gastric peptic ulcer perforation, during and after the surgery, this patient suffered from hyperthyroid crisis. The surgery was successful, with the operation time was about 110 min, and the blood loss was about 50 mL. There was no side injury occurred without blood transfusion, and the patient was cured and discharged on 20 days after operation. The patient was followed up for about 1 year, and the general condition and life returned to normal.ConclusionMDT discussion is a very helpful way in the treatment of gastric perforation combined with hyperthyroidism crisis and can give a better outcome.

ObjectiveTo compare the incidences of peritoneal dialysis (PD)-associated peritonitis among HIV and non-HIV patients, and to analyze the risk factors of PD-associated peritonitis. MethodsEnd-stage renal disease patients with HIV infection who newly started PD in West China Hospital of Sichuan University from 2012 to 2020 were retrospectively included, and non-HIV PD patients in the same period were included as controls at a ratio of 1 to 4. The risk factors of PD-associated peritonitis were analyzed by univariate analysis and multivariate logistic analysis. Kaplan-Meier survival analysis and COX regression analysis were used to compare the peritonitis-free survival between HIV group and non-HIV group. ResultsA total of 60 PD patients were included. The average follow-up time was 31.2±21.3 months. Peritonitis occurred in 7 HIV patients (58.33%) and 8 non-HIV patients (16.67%). Logistic regression analysis showed that HIV infection (P=0.018) and high platelet (>150×109/L) (P=0.032) were independent risk factors for PD-associated peritonitis. The incidence of PD-associated peritonitis in HIV patients significantly increased (HR=10.944, 95%CI 1.503 to 79.707). Kaplan-Meier survival analysis showed that the 5-year peritonitis-free survival of non-HIV group was significantly higher than that of HIV group (75.7% vs. 31.1%) (P=0.003). Multivariate COX survival analysis showed that the 5-year accumulative risk of peritonitis in HIV PD patients was 5.896 times (95%CI 1.508 to 23.043, P=0.01) higher than that of the non-HIV PD patients. ConclusionHIV infection is an independent risk factor for PD-associated peritonitis.
