Objective Statistics and analyze the effect of comprehensive prevention measures for the ventilator associated pneumonia (VAP) morbidity and mortality,and investigate its actual applicate situation in the clinical.Methods Statistics and analyze the clinical date of 183 cases of our ICU mechanical ventilation patients in 2012 (group A),including morbidity,mortality,time of endotracheal intubation,length of stay and the primary pathogenic bacteria,and to compared with the relevant clinical data of 192 cases of our ICU mechanical ventilation patients in 2011 (group B),summarize and analysis the actual applicate situation of the comprehensive prevention measures in the clinical through the data contrast.Results The incidence of VAP in group A was lower than that in group B [31.7％(58/183) vs.58.3％(112/192)] (P ＜ 0.05),but the mortality was no statistical difference in both groups (P ＞ 0.05) ; the endotracheal intubation time and the average length of stay in group A were less than those in group B [6.3 d vs.10.6 d,7.6 d vs.11.9 d](P＜0.05); the main pathogenic bacterium of VAP with mainly gram-negative bacilh.Conclusions Comprehensive prevention measures can effectively reduce the incidence of VAP,but the mortality rate has no significant effect,need further clinical research;comprehensive prevention measures to reduce patients with tube time also confirm its effectiveness.Comprehensive prevention measures are economical and practical,is worth in clinical promotion.

Objective To investigate the effects of 1,25-dihydroxyvitamin D3 in the prevention of corneal allograft rejection. Methods Forty-five SD rats (only right eyes) were used as recipients,and 15 Wistar rats (double eyes) were used as donors. SD rats were randomly divided into 3 groups: the autograft control group,the allograft control group (receiving peanut oil as placebo),and the allograft group were treated with 1,25-dihydroxyvitamin D3 (1.0 ?g.kg-1.d-1,3 times/d for 13 d,i.p.). Drugs were injected intraperitoneally for 14 d after transplantation. Routine antibiotic eye drops were used. Grafts were observed by operating microscopy everyday after transplantation. Five SD rats in each group were killed respectively at the 14,21,and 30 d postoperatively. Neovascularization and inflammation were evaluated with HE staining. ELISA was used to detect the contents of IL-1?,IL-2,IL-8,and IL-10 in the peripheral blood. Results The mean survival time (MST) of the graft was (21.7?6.8) d in the autograft control group,(11.2?2.5) d in the allograft control group,and (19.3?5.2) d in the allograft group. There was statistically significance between the latter 2 groups (P

Objective To study the effect of letrozole (LE) on ovulation in patients with polycystic ovary syndrome (PCOS).Methods One hundred and sixty-four patients with PCOS were divided into LE treatment group (n=68) and chloramiphene (CC) treatment group (n=96).Growth rate of follicles,serum hormone level,endometrial thickness,and cervix mucus were observed before and after treatment.Results The growth rate of follicles was 1.67 and 1.78 mm/d,respectively,in LE and CC treatment groups (P=0.14).The serum T level on the day of LH peak was 2.1?1.9 and 2.0?1.7ng/dL,respectively,in LE and CC treatment groups (P=0.93).The serum testosterone (T) level on day of LH peak and on day 3 of menses was 2.1?1.9 and 1.4?1.5 ng/d,respectively,in LE and CC treatment groups (P=0.09).The serum E2 level on day of LH peak was 89.0?59.5 and 108.1?46.0 pg/ml,respectively,in LE and CC treatment groups (P=0.13).The endometrial thickness was 11.3?1.6 and 9.7?1.4 mm,respectively,in LE and CC treatment groups (P=0.07).The score of cervix mucus was 11.0?1.1 and 8.3?3.1,respectively,in LE and CC treatment groups (P=0.003).Conclusion Letrozole can effectively induce ovulation in patients with polycystic ovary syndrome,and does not increase serum T level.

(2) Frequencies of -67 AG+GG genotype in TPP group were significantly higher than those in GD and CON group(OR=5.32, P

Objective To investigate the changes of protein C and fibrinolytic system in patients with acute cerebrovasculer disease and the influence of intervened treatments on acute cerebral infarction(ACI).Methods Determinations of protein C(PC),protein S (PS),thrombomodulin(TM),Tissue-type plasminogen activater(t-PA),plasminogen activator inhabitor(PAI) were performed in patiens with acute cerebrovasculer disease and normal control(NC),then redeterminated these items after treatments in patients with ACI.Results PC,PS:The levels in patients with ACI were significantly lower than that in other groups.After dreatments,the levels in patients with ACI increased.There were no significantly discrepancy in acute cerebral hemorrhage(ACH) and lacunar cerebral infarct(LCI) compared with NC;TM:The levels in patients with ACH,ACI were significantly higher than that with LCI and NC.After dreatments,the levels in patients with ACI decreased;t-PA:The levels in patients with ACI were lower than NC,whereas the levels in patients with ACH increased.After dreatments,the levels in patients with ACI increased;PAI:The levels in patients with ACI were significantly higher than NC,and also found that the levels in patients with ACH and LCH were higher compared with NC.The levels in patients with ACI decreased after dreatments.Conclusions There are obviously abnormalities in plasma coagulative and fibrinlytic parameters in acute cerebrovasculer disease;To check the levels of PC,PS,TM,t-PA,PAI are important to predict the type of stroke,the seriousness of disease,the effect of treatment,prognosis of the cases and suggest that earlier treatments be important.

Objective To compare the clinical features of myocardial infarction (MI) in young adults with and without diabetes. Methods A total of 94 young adults with MI were enrolled in this study and divided into two groups according to whether they had diabetes:diabetic group (DM) and Non diabetic group (NDM).The clinical features,angiographic results,risk factors and prognosis were compared between the two groups. Results The incidence of atypical chest pain (25.0% vs 7.6%),non-ST segment elevation myocardial infarction (50.0% vs 9.1%),ventricular wall motion abnormalities (78.6% vs 42.4%),double vessels (35.7% vs 21.2%),triple vessels (39.3% vs 3.1%) and the incidence of mortality(10.7% vs 1.5%)were all significantly higher in DM group than in NDM group (P<0.05 or P<0.01).The number of affected vessels and Gensini scores were (2.110±0.875) and (52.61±10.47) in DM group,and(1.140±0.677),(34.02±10.24) in NDM group.The between group difference was statistically significant (P<0.05).Multiple linear regression showed that HbA1c and smoking were the independent risk factors for Gensini score. Conclusion The clinical features of young adult patients with MI and diabetes are more complex,their coronary stenosis are more serious,and the prognosis is poor.Smoking and HbA1c are positively associated with Gensini scores.

Objective To investigate the clinical efficacy of psychological intervention combined with valsartan and Benner Pury in the treatment of congestive heart failure (CHF). Methods 100 patients with congestive heart failure treated in our hospital from January 2015 to October 2016 were selected and randomly divided into the control group and the experimental group, with 50 patients in each group. Patients in the control group were treated with Benner Pury, the experimental group was given valsartan and Benner Pury combined treatment, and psychological intervention, pay attention to the psychological state of patients. The clinical indexes of the experimental group and the control group were compared and analyzed. Results After the corresponding treatment, the effective rate of treatment in the experimental group was 96%, and the effective rate of the control group was 82%. The effective rate of the patients in the control group was significantly lower than that in the experimental group, with statistical difference (P<0.05). The incidence of adverse reactions in the experimental group was 8%, and the fatality rate was 10%. The incidence of adverse reactions in the control group was 10%, and the fatality rate was 12%. There was no significant difference between the experimental group and the control group in the incidence of adverse reactions and mortality, and it was not statistically significant, and could be compared. Conclusion The clinical effect of psychological intervention combined with valsartan in the treatment of congestive heart failure, Benner Pury good, can improve the treatment efficiency to a certain extent, high safety, is further applied in clinical significance.

OBJECTIVE: To explore the effect of treating periarthritis of shoulder with manipulation through evaluating clinical reports with the theory of evidence-based medicine (EMB). METHODS: By retrieval of some main medical literature databases in the past 5 years, 242 articles on treating periarthritis of shoulder with manipulation were available. Selected by admission standard, 10 of them were evaluated with EBM theory. RESULTS: Both single-application and union-application of manipulation were effective to periarthritis of shoulder, but the evaluated articles were all low-quality articles. CONCLUSION: Because of low quality clinic test and larvaceous publication bias, the extant evidence is not enough to recommend replacing other therapeutic methods by manipulation. The low quality of evaluated articles suggests that there exist some methodology problems in the clinic test on treating periarthritis of shoulder with manipulation.
