Objective To investigate the expression of phosphorylated protein kinase B1 (pAkt1) and human telomerase reverse transcriptase (hTERT) in ovarian epithelial carcinoma (EOC) and its relationship with prognosis, and to analyze the correlation between pAkt1 and hTERT expression. Methods 92 patients with EOC in Tangshan Gongren Hospital from January 2012 to December 2016 were selected. The expressions of hTERT and pAkt1 proteins were detected by immunohistochemistry. The relationship between the expressions of pAkt1 and hTERT proteins and their relationship with clinical prognosis were analyzed. Results Of the 92 patients with EOC, 68 cases (73.9 %) had positive expression of pAkt and 52 cases (56.5 %) had positive expression of hTERT. There was no significant correlation between expressions of pAkt1 and hTERT proteins in EOC (r= 0.284, P= 0.633). The expressions of pAkt1 and hTERT proteins were not related with age, tumor pathology type and the International Federation of Gynecology and Obstetrics (FIGO) staging (all P> 0.05), but had significant association with tumor pathology differentiation (χ2= 2.694, P= 0.005; χ2=2.284, P=0.018). The disease-free survival of patients with both pAkt1 and hTERT positive was shorter than that of the other groups (P= 0.013). Conclusion The prognosis of EOC patients with high expression of pAkt1 and hTERT proteins is poor.

Objective To investigate the expression of signal-induced proliferation-associated gene 1 (SIPA1), Ezrin and E-cadherin (E-cad), and their relationship with clinical patterns in epithelial ovarian carcinoma.Methods Immunohistochemistry was used to detect the expression of SIPA1, Ezrin and E-cad in normal ovarian tissue, benign epithelial ovarian tumor, borderline epithelial ovarian tumor and epithelial ovarian carcinoma,respectively. Results The positive rate of SIPA1 expression was 44.2 % (23/52), 64.5 %(20/31), 93.3 % (28/30) and 100.0 % (15/15) in epithelial ovarian carcinoma, borderline epithelial ovarian tumor, benign epithelial ovarian tumor, and normal ovarian tissue, respectively, and there was a statistical difference (χ2 = 29.159, P= 0.000). The corresponding rates were 57.7 % (30/52), 61.3 % (19/31), 90.0 %(27/30) and 93.3 % (14/15) for the positive rate of Ezrin expression (χ2= 14.555, P= 0.002), as well as for 23.1 % (12/52), 58.1 % (18/31), 86.7 % (26/30) and 0 (0/15) for the positive rate of E-cad expression, respectively (χ2= 45.731, P= 0.000). In patients with epithelial ovarian carcinoma, the expression of SIPA1 was correlated with tumor differentiation (χ2=3.895, P=0.048), but not with histological type and clinical stage (all P>0.05). The expression of Ezrin was not correlated with histological type, tumor differentiation and clinical stage (all P>0.05). There was a positive correlation between expression of E-cad and SIPA1, Ezrin in epithelial ovarian carcinoma, respectively (r= 0.339, P= 0.014; r= 0.284, P= 0.041), but no correlation between the expression of SIPA1 and Ezrin (r= 0.214, P= 0.128). Conclusions SIPA1, Ezrin and E-cad play important roles in the occurrence and development of epithelial ovarian carcinoma. They cooperate in the progression and their combined detection can better evaluate the prognosis of epithelial ovarian carcinoma.

Objective To analyze results of bacterial infection distribution and drug sensitivity monitoring in 414 patients with open extremity injuries caused by Wenchuan earthquake so as to provide advices for guiding utility of antibiotics in treatment of patients injured in natural disasters. Methods Bacterial culture of wound secretion substance and drug sensitivity monitoring were done in 414 patients with open extremity injuries. Results There were 12 patients (2.9%) with G+ coccobacteria, 66 (15.9%) with G- bacillus, 2 (0.5%)with G+ bacillus, 6 (1.5%) with multiplicitas infection(5 with dual infection and I with triplication infection). Main pathogenic bacteria were as follows: (1)G+cocco- bacteria including Staphylococcus epidermidis, Staphylococcus aureus and anthropo-staphylococci ; (2) G- bacillus including Aerobacter cloacae, banmanii, escherichia co]i, aerugo pseudomonas, proteusvul- gaffs and Ewingella americana. (3)G+ bacillus including bacillus subtilis. The drugs with high sensi0tivi- ty to G+ coccobacteria included vancomycin, rifampin, levofloxacin and cidomycin, but those with low sensitivity to G+coccobacteria included penicillin, ampicillin and erythremycin. The drugs with high sen- sitivity to G- bacillus included imipenem, amikacin, levofloxaciu and tenebrimycin, but those with low sensitivity to G-bacillus included ampicillin and piperacillin. Conclusions Patients with open ex- tremity injuries caused by earthquake have rather high bacterial infection rate, involving many kinds of in- fection strains. Therefore, we should do bacterial culture and drug sensitivity monitoring of wound excre- tion substance as early as possible to guide rational use of antibiotics.

Objective To investigate the effect of postoperative complications to the aged after total hip replacement.Methods According to hospitalization order,120 patients undergoing total hip replacement operation were assigned into the intervention group and the control group with 60 patients in each group.In the intervention group,the patients received comprehensive intervention of diet nursing,psychological nursing,complication prevention and rehabilitation exercise.The control group received usual care.Then duration of hospital stay,incidence of complication,psychological state and compliance with functional exercises were compared between two groups.Results In the intervention group,the hospitalization time was shorter,the incidence rate of complication was lower,and psychological state and compliance with functional exercises were better than the control group.Conclusions The comprehensive intervention can reduce the incidence rate of complication,shorten hospitalization time,raise quality of care and facilitate recovery of patients.

BACKGROUND: With further understanding of deep venous thrombosis(DVT)following total hip replacement,reduction and prevention of DVT has become hot topic in clinical studies.The reports of DVT formation factors remain controversial due to small samples,little statistical significance,confusion of basic experimental and clinical results and lacks of science.OBJECTIVE: To explore the causes and factors for the early DVT following total hip replacement and summarize measures to prevent and treat early DVT to reduce incidence of complications.METHODS: A total of 1780 cases of primary total hip replacement operation were analyzed retrospectively.The statistical indexes included sex,age,body mass,other system disease,previous hip joint operation,anesthesia,operative time,prosthetic fixation,blood transfusion,postoperative functional exercise,antithrombotics,and complication.Standardized database was built and analyzed by SPSS(version 13).Regression analysis was performed using Binary Logistic Regression.RESULTS AND CONCLUSION: Of 1780 cases,136 had DVT.Age,other system diseases,anesthesia,prosthetic fixation,blood transfusion,postoperative functional exercise and antithrombotics were correlated with early DVT(P < 0.05).Old age,hypertension or diabetes,general anesthesia,fixation of bone cement,whole blood transfusion were the risk factors for early DVT following total hip replacement,while postoperative functional exercise and antithrombotics were the protective factors for DVT.The incidence rate of early complications can be reduced by the methods such as dealing with perioperative treatment carefully,effectively controlling the chronic diseases,efficient evaluation before surgery,precise manipulation,and the postoperative prophylactic treatment and nursing.
