Objective To compare the therapeutic effect of procedure for prolapse and hemorrhoids （PPH） and Block repair procedure for rectocele．Methods A retrospective study of 62 patients with surgical treatment for rectocele was analyzed．The patients were divided into PPH group （n=32） and Block group （n=30） according to the different operation procedure．The symptoms score of improvement of the patients after surgery was compared between the two groups， including operation time，intraoperative blood loss， postoperative pain score， required analgesic times， postoperative complications，hospitalization time，and hospitalization expenses．Results The symptoms of constipation of patients in two groups was significantly improved afer operation．Comparing one month with three months of Longo’s obstructed defecation syndrome （ODS） score after the operation，there was no significant difference in the PPH group（P＞0.05）， but significant difference in the Block group（P＜0.01）．Although the expenses of the PPH group was much higher than that of the Block group （P＜0.01）， the outcomes of the PPH group were much better than those of the Block group （P＜0.01）， including the postoperative Longo’s ODS score of one month and three months，operation time，intraoperative blood loss， postoperative pain score，required analgesic times，and hospitalization time．Two cases of lightly postoperative incontinence occurred in the PPH group，but completely recovered after three months in the clinical follow-up．Conclusions The PPH is as safe and effective as Block repair procedure for rectocele. The short time effect and lower recurrence rate of the PPH are better than those of the Block repair procedure．
Objective To analyze retrospectively the 875 procedures of earthquake related patient in West China Hospital of Sichuan University after the Wenchuan earthquake, so as to provide reference for the improvement of medical rescue for the disaster of earthquake and the establishment of state-level regional medical centers. Methods The analysis was based on the data provided by the Department of Information of the Hospital up until July 11. The software of Microsoft EXCEL was used for data input and statistical analysis. Results Up to July 11, 1 265 operations in earthquake injuries have been performed in the hospital, of which 875 were done in operating rooms. Initial peak of admission to hospital was positively correlated to peak of surgery performed, which the type of the operation was all emergency operation and most of which were amputation (43%). Second peak of surgery was 2 days delayed following admission to hospital. The type of operation mainly was elective surgeries. Most patients received second stage procedure-open reduction and internal fixation (61%). Conclusion Our hospital played a key part in rescue effort following such huge natural disaster. Our prompt response and effective leadership demonstrated our hospital’s flexibility and capability in the state-level hospital near the epicenter.
ObjectiveTo establish a hypertension prediction model for middle-aged and elderly people in China and to use the basic public health service database for performance validation. MethodsThe literature related to hypertension was retrieved from the internet. Using meta-analysis to assess the effect value of influencing factors. Statistically significant factors, which were also combined in the database, were extracted as the predictors of the models. The predictors’ effect values were logarithmarithm-transformed as the parameters of the Logit function model and the risk score model. Participants who were never diagnosed with hypertension at the physical examination of health service project of Hongguang Town Health Center in Pidu District of Chengdu from January 1, 2017, to January 1, 2022, were considered as the external validation group. ResultsA total of 15 original studies were involved in the meta-analysis and 11 statistically significant influencing factors for hypertension were identified, including age, female, systolic blood pressure, diastolic blood pressure, BMI, central obesity, triglyceride, smoking, drinking, history of diabetes and family history of hypertension. Of 4997 qualified participants, 684 individuals were identified with hypertension during the five-years follow-up. External validation indicated an AUC of 0.571 for the Logit function model and an AUC of 0.657 for the risk score model. ConclusionIn this study, we developed two different prediction models based on the results of meta-analysis. National basic public health service database is used to verify the models. The risk score model has a better prediction performance, which may help quickly stratify the risk class of the community crowd and strengthen the primary-level assistance system.
