OBJECTIVE: To construct and validate a prognostic prediction model for children with sepsis using the Phoenix sepsis score (PSS). METHODS: A retrospective case series study was conducted to collect clinical data of children with sepsis admitted to the pediatric intensive care unit (PICU) of the Affiliated Hospital of Guizhou Medical University from January 2022 to April 2024. The data included general information, the worst values of laboratory indicators within the first 24 hours of PICU admission, PSS score, pediatric critical illness score (PCIS), and the survival status of the children within 30 days of admission. The statistically significant indicators in univariate Logistic regression analysis were included in multivariate Logistic regression analysis to screen the risk factors affecting the prognosis of children with sepsis and construct a nomogram model. The receiver operator characteristic curve (ROC curve) was drawn to evaluate the predictive performance of the model. The Bootstrap method was used to perform 1 000 repeated sampling internal verification and draw the calibration curve of the model. RESULTS: A total of 199 children with sepsis were included, of which 32 died and 167 survived 30 days after admission. In the univariate Logistic regression analysis, shock, white blood cell count (WBC), international normalized ratio (INR), lactic acid (Lac), PSS score, and PCIS score were identified as statistically significant predictors. These variables were then included in the multivariate Logistic regression analysis, which demonstrated that shock [odds ratio (OR) = 4.258, 95% confidence interval (95%CI) was 1.049-17.288], WBC (OR = 1.124, 95%CI was 1.052-1.210), and PSS score (OR = 1.977, 95%CI was 1.298-3.012) were independent risk factors for mortality in pediatric patients with sepsis (all P < 0.05). A nomogram model was constructed based on these three risk factors, with the model equation as follows: -4.809+1.449×shock+0.682×PSS score+0.117×WBC. The calibration curve results showed that the model's predictions were highly consistent with the actual observations. The ROC curve showed that when the Youden index of the prediction model was 0.792, the sensitivity and specificity were 90.6% and 88.6%, respectively, and the area under the curve (AUC) was 0.957 (95%CI was 0.930-0.984), which was higher than the AUC of shock, WBC, and PSS score alone (0.808, 0.667, 0.908, respectively). CONCLUSIONS Shock, WBC, and PSS score have demonstrated certain predictive value for mortality in children with sepsis. The nomogram model based on the above indicators has important clinical significance for evaluating the prognosis and guiding treatment of children with sepsis.

Objective To explore the factors associated with the quality of life (QOL) in patients after liver and kidney transplantation.Methods A multicenter cross-sectional survey was carried out in 5 Level Ⅲ Class A hospitals.153 liver transplant recipients and 301 kidney transplant recipients of outpatient clinic follow-up from March to December in 2015 were selected and investigated with a self-designed general state questionnaire,and Quality of Life Scale for Liver and Kidney Transplant Recipients which developed by our research group.Results There were significant differences in QOL total score in liver and kidney transplant recipients among groups of marital status and occupation.Divorced,unemployed and low-educated patients showed lower QOL total score than married,employed and high-educated ones (P ＜ 0.05).As compared with non-living-related transplantation group,patients undergoing living-related transplantation presented a better status in QOL total scores (P＜0.05).The QOL total score was obviously lower in patients suffering from complications and rejection than in those without occurrence of complications and rejection (P＜ 0.01).Postoperative time was correlated positively and significantly with QOL scores,and variances existed among different stages postoperation (P ＜ 0.01).Multivariable regression analysis demonstrated that education,marital status,postoperative time,type of donor and chemotherapy were the factors influencing liver transplant recipients' QOL,while marital status,postoperative time,type of donor,medical care assurance,complications and rejection after operation had effect on kidney transplant recipients.Conclusion Attaching importance to QOF among liver and kidney transplant recipients,and implementing scientific and effective nursing intervention based on the characteristics of them are necessary.

Objective To Establish an evaluation system of the quality of life for Chinese liver and kidney transplant recipients,and develop a specialized scale to measure the quality of life (QOL)for such recipients preliminarily.Methods By combining subjective and objective methods,this study determined the evaluation system and created items of QOL scale based on literature analysis,Delphi method (expert consultation),interviews,and experience of researchers.Then,a nationwide clinical survey was conducted on 5 Level Ⅲ Class A hospitals.454 valid questionnaires were collected,including 153 from liver recipients,and 301 from kidney recipients.Subjective statistical methods such as critical Ratio method,correlation coefficient method,dispersion tendency method,and exploratory factor analysis were used for selection of questionnaire items.Results The study established an evaluation system of QOL for liver and kidney transplant recipients,including 4 primary indexes and 12 secondary indexes,and developed QOL scales that were appropriate for liver and kidney transplant recipients respectively.Conclusions The structure of QOL scale for liver and kidney transplant recipients was basically consistent with theoretical assumption.The QOL scale for patients showed good reliability and validity,therefore,it can fully reflect the quality of their life.

ObjectiveTo investigate prophylaxis and treatment of bile leakage from hepatic duct anomalies after liver transplantation.MethodsWe retrospectively analyzed 3 patients with bile leakage from hepatic duct anomalies after liver transplantation in our institute.The graft procurements were combined liver-kidney harvesting.The reconstruction of the bile ducts was end-to-end anastomoses.ResultsIn the first patient with a right accessory duct joining the cystic duct,leakage of bile came from the stump of the cystic duct after anastomosis of the bile ducts.The original anastomosis was taken down,and reanastomosis was performed after plasty of the bile ducts.The patient recovered uneventfully.In the second patient with a Luschka bile duct,the biliary fistula closed spontaneously after percutaneous drainage.However,re-transplantation was performed for severe infection 7 month after the primary transplantation.In the third patient with an accessory hepatic duct from the right posterior sector joining the common bile duct,the bile duct stump which we missed leaked bile.Re-transplantation was performed because of severe complications.Conclusion Understanding the anatomy of intra- and extra-hepatic bile ducts and their common anomalies identifying the structures in the porta hepatis during preparation of the liver grafts,and looking for possible accessory hepatic ducts and aberrant bile ducts are important steps to prevent bile leakage in liver transplantation.

Objective To invastigate the effect of living donor liver transplantation(LDLT) with middle hepatic vein(MHV) and LDLT without MHV on the donor. Methods Between August 2007and August 2008, 62 LDLT were performed, 30 LDLT with MHV (group A), 32 LDLT without MHV (group B). Before operation, comprehensive assessment the graft size, remnant liver volume (RLV), fatty liver, MHV type, and the level of portal hypertension in recipient to determine whether harvested MHV. The graft was harvested depending on the port vein and hepatic artery ischemia-line,ultrasound was used to definite the branch of MHV. The donor operative time, intraoperative blood loss, postoperative hospital stay, bilirubin, INR, ALT, albumin, and complications were recorded in detail. Results Operative time, blood loss, hospital stay between group A and group B were not significant difference. But the bilirubin, INR, ALT in group A was higher than group B; Albumin recovered slower and with more ascites in group A. The early complications post-operation were similar in the two groups. There were 2 cases with wound infection in group A and 3 in group B. 3 cases complicated with cholestasis in group A and 1 case in group B, all of them gradually recovered to normal after 2 weeks. 2 cases occurred cross-section bile leakage in either group, the patients administrated with anti-infection, external drainage and recovered;4-7 days after operation, there were 6 cases in group A and 5 cases in group B occurred delayed gastric emptying, it was alleviated after adjust diet, encouraging activities and administrated with gastrointestinal motility drugs. Conclusion Right graft with the middle hepatic vein may lead donor recovery delayed, but with precise evaluation, especially MHV type, remnant liver volume (RLV%)＞30%, preserve the drainage of V4b and the artery segment Ⅳ,it's can ensure the donor's safety.
