Objective To observe changes in plasma level of brain natriuretic peptide ( BNP), left ventricular function in acute myocardial infarction (AMI) patients and discuss the effect of atorvastatin in these patients. Methods Eight patients with acute myocardial infarction hospitalized from October 2006 to December 2008 in our department were enrolled in the study. The AMI patients were further randomly assigned into the conventionsl treatment group ( n = 38 ) and atorvastatin treatment group ( n = 42 ). In the conventional group all patients took ACEI, beta-blocker, nitrate drugs, aspirin and low molecular beparin as their conventional therapy without medication taboo. In the atorvastatin group all patients took atorvastatin 20 mg per day for three months in addition to the conventional treatment. Twenty healthy individuals were testified by coronary arteriongraphy and ultrasonic cardiogram selected as controls ( n = 20). LVEDd, LVEF and left ventricular fractional shortening (LVFS) of 80 patients with AMI and 20 healthy controls were examined by ultrasonic cardiography and their plasma concentrations of BNP were measured. As to the conventional and atorvastatin group, the parameters were tested on the day of hospitalization (within 24 hours of AMI) ,also at the 3rd week and 3rd month after treatment. All data were analyzed statistically by SPSS12. 0. Results There were no significant changes in LVEDd, LVEF, LVFS after 3-week treatment compared to pre-treatment ( P ＞ 0.05 ), but significant changes after 3-month treatment ( P ＜0. 01 ) in 2 AMI groups. Moreover, LVEDd, LVEF, LVFS in the atorvastatin group were significantly greater than the conventional group (P ＜ 0.05). The plasma levels of BNP measured within 24 hours of AMI onset in two treatment groups were significantly higher than the control group. The plasma BNP level decreased significantly after 3 - week and 3-month treatment( all P value ＜0. 01 )in both treatment groups and atorvastatin group showed even lower BNP level with comparison to the conventional group( P ＜0.05 ). The plasma BNP in myocardial infarction patients after three months of treatment were negatively correlated with LVEF( r1 = -0.48 ,r2 = -0.58 ,P ＜ 0. 01 ) which implied a close relationship between BNP and heart function. Conclusions The changes of plasma BNP is earlier than that of heart structure. The long-treatment usage of atorvastatin may improve cardiac function, decrease the plasma BNP and convert ventricular remodeling,which benefit patients besides lipid managing. The plasma BNP could be used as a sensitive indicator of the treatment response and a useful index for evaluating the heart function and pronosis in AMI patients.

Objective To research on study attitudes of military medical university undergraduates. Methods The study attitudes of all the undergraduates were investigated and compared in different sorts by using homemade questionnaires. Results The general study attitudes of military medical university undergraduates were good. The undergraduates of different grades had not different study attitudes, neither did the undergraduates of different ages. The undergraduates of different sorts had different attitudes, so did the undergraduates of different genders and different specialties. Concretely, the undergraduates not recruited by Army, the men undergraduates, the undergraduates of long academic-year program and five-year military medico have better study attitudes. Conclusion The general study attitudes of military medical university undergraduates were good but there is still some space to boost. All sorts of steps should be taken to correct their study attitudes and advance their study effects.

Objective: To study the microwave assisted extraction process for saponins and isofraxidin in Radix Acanthopanacis Senticosi as a marker. Methods: Using the uniform design, the optimization process of microwave assisted extraction for saponins and isofraxidin in Radix Acanthopanacis Senticosi was gained by continuous microwave radiation. Results: Some parameters such as microwave power, radiation time, solvent concentraction, solvent consumption, pulverized degree and dipping time had interactions on the extraction of active constituents in Radix Acanthopanacis Senticosi. Conclusion: The optimization process was obtained which could be described as following: 510W as the microwave power, 30 min as the radiation time, 85% ethanol as the solvent, 1∶5 as the proportion of raw material to solvent, 40 mesh as the grinding degree and 0.5 hr as the dipping time. Meanwhile, the model developed were proved to be reasonable by the pilot experiment.

Object To study the microwave-assisted extraction process of Radix Polygoni Multiflori. Methods Using the uniform design, the optimization process of microwave-assisted extraction for total anthraquinones and 2, 3, 5, 4′- tetrahydroxystilbene-2-O-?-D-glucoside in Radix Polygoni Multiflori was gained by continuous microwave radiation. Results Some parameters, such as microwave power, radiation time, solvent concentration, solvent consumption and dipping time had interactions to the extraction of active ingredients in Radix Polygoni Multiflori. The best optimization process was obtained as following: 340 W as the microwave power, 10 min as the radiation time, 95% ethanol as the solvent, 1∶5 as the proportion of solid to liquid and 1 h as the dipping time. Conclusion The established models were proved to be reasonable by the verified experiment.

Object To study microcosmic mechanism about microwave-assisted extraction (MAE) to Radix Puerariae (RP) and Radix Caulis Acanthopanacis Senticosi (RCAS). Methods By transmission electron microscope, the structure changes about tonoplast in RP and RCAS were observed. Results The effect on tonoplast was differently made by MAE and conventional reflux extracting method. Conclusion The effective ingredients could be dissolved more easily with MAE than conventional reflux extracting method.

Objective:To investigate the impact of social determinants of health on the inequality of child health and health care utilization.Methods:Information of 1 118 children aged 0 to 16 is extracted from the Chinese Family Panel Studies(CFPS)year 2008 cross sectional survey data for the analysis.Age standardized concentration curves and concentration indices are employed to assess the inequalities for incidence of low birth weight,self reported good health,adequate timing of breast feeding,health insurance coverage and incidence of catastrophic health expenditures for these children.Concentration indices are decomposed to four levels of social determinants of health(community,family,mother and individual level)to understand their contributions to health inequality respectively.Results:There are health inequalities existing in the investigated children,among which social factors at mother and family level have the largest contribution.Conclusion:To respond to the call by the WHO to achieve health equity through action on the social determinants of health in a generation,the inequalities of health and health care utilization amongst Chinese children should be put on the policy agenda,and social policies should intervene from multiple social dimensions,especially from family and mother levels.

AIM: To study the microwave-assisted extraction process of forsythin from Forsythia Suspensa. METHODS: The optimization process for forsythin in Forythia Suspensa was gained by uniform design. RESULTS: The optimization process was obtained as following: 60% ethanol as solvent at the 680 W microwave power,40 min as the radiation time,5∶1(w/w) as the proportion of solvent to raw material and 30 min as the soaking time. CONCLUSION: In comparison with the traditional extraction,the forsythin content of target substance used the microwave-assisted extraction was higher than the former,and the extraction efficiency was also much better.
