ObjectiveTo develop the military acute stress scale and examine the reliability and validity of this scale.MethodsBased upon the previous acute stress researches and the rule of psychometrics,the military acute stress scale was compiled according to open-ended inventory survey.A total of 630 personnel were chosen by random cluster sampling,and tested with this scale,50 of them were tested by Chinese Military psychosomatic health Scale simultaneously,and 50 of them were retested after two week.The reliability and validity were examined by exploratory factor analysis,confirmatory factor analysis and correlation analysis.ResultsThe military acute stress scale was comprised of 9 factors and one lie sub-scale ; Main fit indexes of model were the following CMIN =1219.476,DF =593,P =0.000,CMIN/DF =2.056,IFI =0.927,TLI =0.902,CFI =0.924,RMSEA =0.059; The conrelation coefficients between subscales and subscales were 0.284-0.572.The correlation coefficients between subscales and total scale were 0.700 ～ 0.846 (P ＜ 0.05 or 0.01 ) ; The correlation coefficients was significant between this scale and Chinese military psychosomatic health scale.The correlation coefficients were 0.338-0.962 (P ＜ 0.01 ).The test-retest correlation coefficients of total scale and subscales were 0.379-0.909 (P ＜ 0.01 ).The Cronbaeh's α coefficients were 0.606-0.926 ; and the split-half correlation coefficients were 0.466-0.855.ConclusionThe military acute stress scale has acceptable psychometrics properties on reliability and validity.

Adenomatous polyposis coli gene is an important anti-oncogene of the Wnt signaling pathway. The promoter hypermethylation of APC gene can effect the expression of APC mRNA and APC proteinum, which can make Wnt signaling pathway anomalous. Recently. the promoter hypermethylation of APC Gene in gynecological tumors is found in many studies, and it is related to the aggravation level of tumor.This paper reviews the influencing factors and progress of promoter methylation of APC gene in Gynecological cancer.

The incidence of malnutrition among patients with chronic kidney disease (CKD) constantly increases despite the development of health care and dialysis techniques.New nutritional targets for CKD patients upon maintenance treatment have been developed.Before dialysis,evidences have shown that a long-term nutritional care plan,with a control of protein intake,can effectively correct metabolic disorders including proteinuria and acidosis.During the maintenance dialysis,the optimal protein and energy intakes have been recently challenged.The new classification of nutritional disorders in CKD patients may help the easily identification of protein-energy wasting.

Reading therapy in hospital libraries, academic libraries and public libraries was described in terms of its theoretical study and practical study,and its significance in hospital library was elaborated by comparative analysis.

Objective To evaluate application effectiveness of quality control circle (QCC)in increasing the face mask wearing rate of hospitalized pulmonary tuberculosis (TB)patients.Methods Nine nurses in department of tu-berculosis formed a ‘circle’,the theme of ‘improving the face mask wearing rate of hospitalized pulmonary TB pa-tients’was established,rectification measures were formulated and implemented,face mask wearing rates of pa-tients before and after implementing QCC activities were analyzed statistically.Results The face mask wearing rate of hospitalized pulmonary TB patients after implementing QCC activities was higher than that before implementing QCC activities (87.50% [147/168]vs 65.54%[116/177],P <0.05).The abilities of every ‘circle member’have been improved in the following aspects:problem-solving skills,sense of responsibility,communication skills,self-confidence,team working,enthusiasm,quality-control techniques,and cooperation abilities,the total average score increased from 23.78 before implementing QCC to 33.78 after implementing QCC.Conclusion QCC activities can not only improve the face mask wearing rate of hospitalized pulmonary TB patients,but also enhance circle mem-bers’quality-control skills and team spirit.

Objective To assess the efficacy and safety of autologous drainage blood reinfusion in total knee arthroplasty(TKA). Methods Computers were used to search the Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, and VIP. The randomized controlled trials (RCTs) of autologous drainage blood reinfusion and vacuum suction without reinfusion after TKA were collected. And the results were analyzed by using the software RevMan5.1. Results Eight RCTs met the criteria for meta-analysis. Use of autologous drainage blood reinfusion significantly reduced the average amount of units of homologous blood transfusion, the length of hospital stay, and the number of patients requiring homologous blood transfusion. The rates of DVT formation and incision infection did not differ significantly between the two groups. Conclusions Autologous drainage blood reinfusion is a safe, effective procedure with less blood transfusion and medical cost. It can lower volume of allogeneic blood transfusion , shorten length of hospital stay, and avoid occurrence of complications.

The WeChat service provided at present in 14 hospitals directly under the Yunnan Health and Family Planning Commission was surveyed with suggestions proposed for providing active Wechat service in hospitals in order to alleviate the difficulty to see a doctor and the tense relationship between doctors and patients.

Cervical artery dissection (CeAD) is an important cause of ischemic stroke in young adults w ith ischemic stroke. The clinical manifestations are often local facial pain, Horner syndrome, and ischemic stroke. With the development of noninvasive imaging, many patients w ith CeAD have got early diagnosis. Thromboembolism is an important mechanism of its pathogenesis. Timely giving anticoagulation therapy is reasonable. How ever, anticoagulants may lead to intramural hematoma expansion; therefore, there are also people w ho support antiplatelet therapy. How ever, the effectiveness of the 2 regimens needs to be confirmed by randomized trials. The recently completed Cervical Artery Dissection in Stroke Study (CADISS) in patients w ith stroke is the first prospective study aiming at the problem. The results have show ed that there w as no significant difference in efficacy betw een the anticoagulants and the antiplatelet drugs. Thrombolysis in patients w ith acute CeAD can not increase the risks of hemorrhage, and the rate of good functional outcome is similar to that of the control group. Therefore, it can be used as a treatment method in acute phase. For patients w hose antithrombotic treatment is invalid or having contraindications and repeated recurrent stroke can conduct endovascular intervention or surgical treatment. Usualy, the prognosis of patients w ith CeAD is better. The stroke recurrence rate is low . The abnormal arterial w als in more than half of the patients w il disappear at 3 to 6 months.

OBJECTIVE: To investigate the function of activator protein-1 (AP-1) in proliferation and collagen synthesis of cardiac fibroblasts (CFs) in neonatal rats induced by tumor necrosis factor-alpha (TNF-alpha), and to explore the mechanism of Qiangxin Decoction (QXD), a compound traditional Chinese herbal medicine, in reversing cardiac fibrosis. METHODS: CFs derived from neonatal rats were cultured with enzymatic dissociation, and fibrosis of the CFs was induced by TNF-alpha. The CFs were divided into normal control group, untreated group, 5% QXD-containing serum group, 10% QXD-containing serum group and 20% QXD-containing serum group. After 24-hour culture of QXD-containing serum, AP-1 mRNA was detected by real-time fluorescent quantitative polymerase chain reaction; proliferation and collagen synthesis of CFs were assayed by thiazolyl blue assay (MTT) and measured by hydroxyproline respectively, in order to determine the effect of different dosage decoction on the proliferation and collagen synthesis of CFs. RESULTS: After 24-hour stimulation of TNF-alpha in CFs, compared with those in normal control group, the expression of AP-1 mRNA and cardiac fibroblast proliferation and collagen synthesis increased significantly (P<0.05). However, Qiangxin Decoction could reduce the expression of AP-1 mRNA and decreased the proliferation and collagen synthesis of CFs significantly (P<0.05). CONCLUSION: Qiangxin Decoction can inhibit proliferation and collagen synthesis of CFs induced by TNF-alpha, and reverse cardiac fibrosis, which may be related to its down-regulation of the expression of AP-1.
