Objective To explore and analyze the related factors of nosocomial infection in patients after total laparoscopic hysterectomy.Methods A total of 231 patients undergoing total laparoscopic hysterectomy were enrolled in this study and their data were retrospectively analyzed.The related factors such as uterus size,operation duration,intraoperative blood loss,type of disease,drainage tube,hospital duration before surgery,and history of pelvic surgery were analyzed.Results Among the 231 cases undergoing total laparoscopic hysterectomy,23 cases had infection and the infection rate was 9.96％.Univariate analysis showed uterus size,operation duration,intraoperative blood loss,hospital duration before surgery,and history of pelvic surgery had influence on postoperative infection and the difference had statistical significance (P＜0.05),while the difference of age and drainage tube had no statistical significance on postoperative infection (P＞0.05).Conclusion The incidence of infection after laparoscopic hysterectomy is related to uterus size,operation duration,intaoperative blood loss,hospital duration before surgery,and history of pelvic surgery.

Objective To observe serum and callus leptin expression in rats model with fracture and traumatic spinal cord injury (SCI). Methods 72 male SD rats were randomized equally into 4 groups: control, SCI group, fracture group, and fracture/SCI group. Rats were sacrificed at 7, 14, 21 and 28 days after fracture/SCI. Serum leptin was detected by radioimmunoassayat 1, 7, 14, 21 and 28 days, and callus formation was measured radiologically at 14, 21 and 28 days. Callus leptin was analyzed with immunohistochemistry. Results Serum leptin in the fracture group, SCI group and combined fracture/SCI group were all higher than in control group at the 1, 7, 14 and 21 day time-point (P < 0.05). Serum leptin in the combined fracture/SCI group was significantly higher than the fracture group at 7, 14 and 21 days (P < 0.05), and higher than SCI groups at 14 and 21 days after operation (P < 0.05). The percentage of leptin-positive cells in the fracture/SCI callus, and callus volume was significantly higher than the fracture-only group (P < 0.001). Conclusions Leptin expression increases in the recovery process after SCI, and the recovery of fracture becomes sooner.

OBJECTIVETo explore the effect of donations after cardiac death (DCD) kidney transplant performed in northwest China and the measures for management of delayed graft function (DGF).

METHODSIn the period of 2011-2013, a total of 51 families of DCD donor gave their consent to organ donation by signing the informed consent with the help by a Red Cross Organization (ROC) coordinator, and 102 kidneys were retrieved by organ procurement organization (OPO) teams. Ninety-four operations of renal transplantation were carried out in our hospital. All the patients were followed-up and based on the occurrence of DGF after transplantation, they were divided into DGF group and non-DGF group for comparative studies.

RESULTSThe success rate of donation after cardiac death was 29.3%, and the incidence of post-transplantation DGF was 27.7%. The 1-year human/kidney survival rate was 98.9%/95.7%. Within six months after the transplant, the values of eGFR in DGF group were significantly lower and serum creatinine significantly higher than those in non-DGF group (P<0.05), but no significant differences were found between the two groups thereafter (P>0.05). The occurrence of DGF in LifePort mechanical perfusion cohorts was significantly lower than that in the simple cold preservation group (21.5% vs. 41.4%, P<0.05).

CONCLUSIONThe overall effect of DCD kidney transplant is good despite a high incidence of early DGF, and we recommend the use of low-temperature mechanical perfusion for storage and transportation of DCD donor kidney.

Uncovering the risk factors of pulmonary hypertension and its mechanisms is crucial for the prevention and treatment of the disease.In the current study,we showed that experimental periodontitis,which was established by ligation of molars followed by orally smearing subgingival plaques from patients with periodontitis,exacerbated hypoxia-induced pulmonary hypertension in mice.Mechanistically,periodontitis dysregulated the pulmonary microbiota by promoting ectopic colonization and enrichment of oral bacteria in the lungs,contributing to pulmonary infiltration of interferon gamma positive(IFNγ+)T cells and aggravating the progression of pulmonary hypertension.In addition,we identified Prevotella zoogleoformans as the critical periodontitis-associated bacterium driving the exacerbation of pulmonary hypertension by periodontitis,and the exacerbation was potently ameliorated by both cervical lymph node excision and IFNγ neutralizing antibodies.Our study suggests a proof of concept that the combined prevention and treatment of periodontitis and pulmonary hypertension are necessary.

Objective To investigate the incidence and related factors of postoperative hemorrhage, so as to provide data support for preventing its occurrence and developing reasonable risk assessment tools. Methods The retrospective analysis of clinical data of 50 patients with postoperative hemorrhage after surgical operation in a 3A hospital in Shanghai from January to December 2016 was conducted. A 1:2 matching case-control study was conducted to explore the risk factors of postoperative bleeding in surgical patients by univariate and multivariate regression analysis.Results The total number of surgical operations (excluding obstetrics and gynecology, five senses) was 18942. Postoperative hemorrhage occurred in 50 cases, including 6 deaths. The incidence of postoperative hemorrhage was 0.26％ and the mortality rate was 12％. The incidence of postoperative bleeding in the top four departments were gastrointestinal surgery (13 cases), hepatobiliary and pancreatic surgery (11 cases), cardiac surgery (10 cases), neurosurgery (9 cases). The statistical analysis of binary Logistic in the case group and the control group showed that postoperative albumin<35g/L, postoperative AST abnormality, postoperative ALT abnormality, postoperative hypertension were independent risk factors of postoperative bleeding.Conclusions The incidence of postoperative bleeding in this hospital is relativelylow, but the mortality is relatively high. Medical staff should pay more attention to the patients undergoing gastrointestinal, liver, pancreas, heart and brain surgery. It is also necessary to pay more attention to the blood pressure, albumin and liver function of the patients after operation,and establish the evaluation of prevention of hemorrhage, which has a certain early warning effect on the prevention of postoperative hemorrhage.

Objective To investigate the related factors for the survival of the patients with pancreatic cancer.Methods A total of 1 620 patients confirmed as pancreatic cancer admitted in Sun Yat-sen Memorial Hospital affiliated with Sun Yat-sen University,Tumor prevention and treatment center affiliated with Sun Yat-sen University and People's Hospital of Guangdong Province from 2004 to 2016 were retrospectively analyzed,and the effects of TNM staging,surgical treatment,palliative chemotherapy and postoperative assisted chemotherapy on the survival of the patients with pancreatic cancer were examined by life table and Log-rank test.Results The median survival time of all 1 620 cases was 7.15 months.The median survival time of TNM stage Ⅰ,Ⅱ,Ⅲ and Ⅳ was 12.50 months,10.12 months,9.56 months and 5.43 months,and there was statistically significant difference (P =0.001).The median survival time of cases who did not undergo surgery was 6.10 months,which of patients who underwent radical surgery was 13.67 months,and the difference was statistically significant (P =0.001).The median survival time of cases without chemotherapy was 5.55 months,which of patients who underwent palliative chemotherapy was 7.58 months,and the difference was statistically significant (P =0.001).The median survival time of cases with pure radical surgery without chemotherapy was 12.38 months,which of patients who underwent adjuvant chemotherapy was 14.50 months,and the difference was no statistically significant (P =0.561).Conclusions Early diagnosis followed closely by radical surgery is the key to prolong the survival of pancreatic cancer patients.And adjuvant chemotherapy for patients who lose surgery opportunity may improve clinical prognosis to a certain extent.

ObjectiveTo explore the establishment of performance assessment indicators for the classification and grading of public health staff in district-level Centers for Disease Control and Prevention (CDCs), and to provide a basis for such evaluations. MethodsThrough literature review and group interviews, performance evaluation indicators were developed based on competency evaluation. Experts were invited to evaluate the weight of performance evaluation indicators for public health staff from different categories, with the average value used to represent the weight of each indicator. ResultsTwenty-nine experts from universities in Shanghai, municipal CDCs, and district CDCs participated, yielding an expert authority coefficient of 0.86. The performance evaluation indicators for department managers were categorized into three levels, with 4 indicators at the primary level, 16 indicators at the secondary level, and 42 indicators at the tertiary level, while those for general staff included 4 primary indicators, 15 secondary indicators, and 36 tertiary indicators. Significant differences were observed in the weight coefficients of the primary indicators (internal operations, professional work, and learning and growth) between department managers and general staff. The top three secondary indicators for department managers were department management, monitoring and prevention, and level of expertise. For mid-level and senior staff, the top three secondary indicators were monitoring and prevention, level of expertise, and research work. The top three secondary indicators for junior staff were monitoring and prevention, professional expertise, and professional attitude. No significant statistical differences were found among tertiary indicators. ConclusionThe developed performance evaluation indicators are reliable. Staff at different levels and classifications should be evaluated using different performance evaluation standards to accurately reflect individual performance and contributions.
