Objective: To observe the clinical effect of sodium nitroprusside and dopamine injected by micro pump for the treatment of refractory heart failure. Methods:One hundred and six cases of patients with refractory heart failure were chosen as the research object, which were cardiac functionⅢ~Ⅳlevel. All patients were treated with sodium nitroprusside and dopamine injected by micro pump. Starting dose of sodium nitroprusside was 6.25 μg/min. At same time pumping dopamine, starting dose of 2 g/kg·min, the dose was increased gradually until blood pressure dropped to 90~100 mm Hg, continuous 7~10 d, the signs and symptoms after treatment and parameters of cardiac function and adverse reactions were observed. Results: 1)In 106 cases of patients with refractory heart failure after treatment, the total effective rate 85.85%(91/106). 2)The heart rate, blood pressure, cardiothoracic ratio, left ventricular short axis reduced rate,cardiac output, each index of cardiac,indexes of left ventricular ejection fraction were improved significantly after treatment. Conclusion:The clinical effect for the treatment of refractory heart failure by using the micro pump injection of small doses of sodium nitroprusside combined dopamine would be obvious, have less adverse reactions, worthy of clinical popularization and application.

Objective To analyze the changes of Tpeak-Tend interval (Tp-Te) in patients with type 2 diabetes mellitus (T2DM),and to explore the relationship between the changes of Tp-Te and ventricular arrhythmias. Methods A total of 112 patients with T2DM were selected from the Department of endocrinology of our hospital from June 2014 to May 2016 (T2DM group),and 65 subjects underwent healthy physical examination in our hospital were selected as the normal control group (NC group) during the same period.The general data,fasting plasma glucose (FPG),glycosylated hemoglobin (HbA1c),Tp-Te,Tp-Te dispersion (Tp-Ted) were compared between the two groups.The changes of Tp-Te in patients with or without ventricular arrhythmia in T2DM group were also analyzed. Results The FPG,HbA1c,LDL-C,TC and heart rate were significantly higher in T2DM group than in the NC group (P<0.05).Compared with the control group,V5 lead Tp-Te and Tp-Ted in T2DM group was significantly prolonged (P<0.05).IN T2DM group,V5 lead Tp-Te and Tp-Ted were significantly longer in patients with ventricular arrhythmias than in patients without ventricular arrhythmia (P<0.05).Multiple logistic regression analysis showed that the increase of HbA1c and FPG were independent risk factors for prolonged Tp-Ted,and Tp-Ted was an independent risk factor for ventricular arrhythmia. Conclusion Patients with T2DM are more likely to have prolonged Tp-Ted.The prolonged Tp-Te and Tp-Ted could increase the incidence of ventricular arrhythmias.

Objective: To investigate the status of the quality of life (QOL) and its related factors of graduate students in military medical universities. Methods: 189 graduate students of a military medical university were assessed with WHO Quality of Life-BREF, Eysenck Personality Questionnaire (EPQ), Life Event Scale, Perceived Social Support Scale, and Simplified Coping Style Questionnaire. Results: The scores of QOL of graduate students in the military medical university were higher than average; The four domains of QOL were significantly correlated with introversion- extroversion, neuroticism, life event, social support, and coping style. The result from multiple regression showed that introversion- extroversion, neuroticism, social support, life event, and negative coping style were main factors influencing QOL. Conclusion: The status of the QOL of graduate students in military medical universities was pretty good; Their QOL could be improved by these factors, such as keeping stable emotion, developing extroversion, seeking social support, relieving the influence of bad life event, reducing negative coping behavior.

OBJECTIVE: To investigate the expression and clinical significance of ZEB2 and E-cadherin mRNA and protein in nasopharyngeal carcinoma (NPC) tissues. METHOD: The expressions of ZEB2 and Ecadherin in 39 cases of NPC tissue and 12 cases of nasopharyngeal inflammation tissue were detected by Real-time PCR method and immunohistochemical technique. To assess their correlations with clinicopathological parameters of NPC and the interrelationship between them. RESULT: Both the expression of ZEB2 mRNA and protein were higher in NPC tissues than that in inflammation tissues (P < 0.05). Abnormal expression of ZEB2 mRNA and protein in NPC were significantly associated to N stage and clinic stage (P < 0.05), but the difference in expression between the different gender, age and T stage were not statistically significant (P > 0.05). Both the expression of Ecadherin mRNA and protein were higher in NPC tissues than that in inflammation tissues (P < 0.05). Abnormal expression of Ecadherin mRNA and protein in NPC were significantly associated to N stage (P < 0.05), but the different expression between the different gender, age, T stage and clinic stage were not statistically significant (P > 0.05). In NPC tissues, the expression of ZEB2 mRNA was negative correlated with the expression of E-cadherin mRNA (r = -0.367, P < 0.05). The expression of ZEB1 protein was negative correlated with the expression of E-cadherin protein (r = -0.322, P < 0.05), the differences were both statistically significant. CONCLUSION The expression of ZEB2 was up-regulated in NPC, while the expression of E-cadherin was down-regulated, their expression was significantly negative correlated, and might be associated with metastasis of NPC, ZEB2 may promote the invasion and metastasis of NPC by inhibiting the expression of E-cadherin.

Type III polyketide synthases (PKSs) from plants produce a variety of plant secondary metabolites with notable structural diversity and biological activity. These metabolites not only afford plants the ability to defend against pathogen attack and other external stresses, but also exhibit a wide range of biological effects on human health. Several plant PKSs have been identified and studied in recent years. This paper summarized what was known about plant PKSs and some of their aspects such as molecular structure, reaction mechanisms, gene expression and regulation, and transgenic engineering. The review provides information for manipulating polyketide formation and further increasing the scope of polyketide biosynthetic diversity, as well as new avenues for developing transgenic engineering of type III PKSs.

Objective To investigate the relationship between brachial ankle pulse wave velocity and the incidence of cardio-cerebral events in people aged over 40. Methods Cluster sampling method was used to prospectively study 4 380 residents aged over 40 in Guiyang City District from May to August in 2011. Data of ba-PWV were collected. The follow-up examination was conducted from July to November of 2014. According to ba-PWV values, participants were divided into three groups:<14 m/s (control, n=1 039) group, 14-17.9 m/s group (n=1 393) and≥18 m/s group (n=809). Multi-factor Logistic regression model was used to analyze the relationship between ba-PWV values and risk factors of cardio-cerebral events. Results After three-year follow-up, a total of 3 241 participants were included in the final analysis. The cardio-cerebral events were identified in 63 (2.0%) cases, which were 0.6%, 2.2%and 3.2%in control group, 14-17.9 m/s group and≥18 m/s group. The value of ba-PWV increased significantly in those two groups compared with that of normal group. Logistic regression analysis showed that the incidence rates of cardiovascular and cerebralvascular events in 14-17.9 m/s group and≥18 m/s group were 2.777 (1.123-6.864) and 2.786 (1.032-7.526) times of control group after adjusting age, gender, systolic blood pressure, risk factors of diabetes, hypertension and blood lipids. Conclusion There is higher incidence rate of cardio-cerebral events in people aged over 40 in higher ba-PWV group. The value of Ba-PWV can be used to predict the occurrence of cardio-cerebral events.
