In recent years,more and more researchers have realized the possibility that algicidal bacteria could be a useful tool in reducing the impact of harmful algae blooms. In this review, the ecological roles of algicidal substances was briefly discussed, then special emphasis placed on the categories and extract methods of algicidal substances which have been reported. Some ideas for the further studies on algicidal substances were also proposed.

Objective:To understand the awareness of students of medical colleges sperm behavior, attitudes and prac-tical factors. Methods:Used convenient sampling method to select 300 college students of 4 medical colleges in Shanghai conducted a questionnaire survey and used Epidata 3. 1 and SPSS 18. 0 to count and analyse. Results: 251 question-naires. 39. 8% of respondents were willing to sperm, the primary reason was considered to be an act of charity, helping others;willing sperm donors only distributed among schools statistically significant (P<0. 05) proportions, and for the various professional and grades , showed no significant difference ( P>0 . 05 ) . Conclusion:Students of Shanghai Medical Colleges sperm voluntary rate was not high, so the survey analyzed related factors affecting sperm donation and put forward practical proposals to provide reference data and methods for sperm bank sperm recruiting for volunteers in the universities.

Objective To investigate the influence of lipid metabolic markers on hip osteoarthritis (OA) and the correlation with the pain of hip.Methods In this retrospectively cross sectional analysis,393 subjects fufilling the inclusive criteria were continuously included from June 2013 to September 2014.The presentation of hip X-ray of subjects were classified into OA group and non-OA group in terms of Kellgren-Lawrence grading scale,the subjects with Kellgren-Lawrence (K-L)≥2 was classified into OA group.The average of age in total was (62±9) years.There were 183 males and 210 females,the number of patients with OA was 182.There were 210 patients with hypertension and 118 patients with diabetes while the number of smoking patients was 74.The demographic information,risk factors,blood pressure,blood glucose,lipid metabolic markers were analyzed.Differences in proportions were compared using the Chi-square test.Difterences in continuous variables were tested for statistical significance using t test analysis.VAS score was used to evaluate the severity of hip pain.Independent risk factors were confirmed by using multiple logistic regression analysis.The correlation between the risk factors and severity of hip pain was analyzed by Spearman correlation analysis.Results Statistically significance existed in age (t=-4.849),sex (x2=8.946),BMI (t=-4.794),hypertension (x2=4.751),smoking (x2=7.062),metabolic syndrome (x2=34.406),apolipoprotein A1 (t=2.352),apolipoprotein B (t=-6.870),high density lipoprotein cholesterol (t=2.519),triglyceride (t=-4.652) and ApoB/ApoA1 ratio (t=-4.901) between OA group and non OA group.Age [OR =1.060(1.033,1.086)],metabolic syndrome [OR=3.682(2.284,5.938)] and ApoB/ApoA1 ratio [OR=5.743(2.393,13.785)] were the independent risk factors.The ApoB/ApoA1 ratio had positive correlation with the severity of hip pain(r=0.379).Conclusion ApoB/ApoA1 ratio is the independent risk factor of hip osteoarthritis,and has positive correlation with the severity of hip pain.The ApoB/ApoA1 ratio should be monitored in hip osteoarthritis patients in clinical work,to get the relief of pain and improve hip osteoarthritis.

ObjectiveTo evaluate the adequacy of hemodialysis by online clearance monitoring (OCM) and Kt/V of correlation analysis.MethodsThe Kt/V values of 48 maintenance hemodialysis patients in the Department of Nephrology of General Hospital of PLA were accessed by both OCM of Germany BeiLang Dialog + hemodialysis machine and single-pool urea kinetic model.The Kt/V calculation value was also checked by the urea dynamics - room variable volume model.The results generated at different time point were compared,including at the real time,before and after appearing through blood by On - line Clearance Monitoring,and correlation analysis of Kt/V value was performed.ResultsThere was no significant difference on evaluating the level of Kt/v by these two methods.The relationship between the results of the two methods was significantly positive related.(r=0.539,P ＜ 0.01).ConclusionsDuring hemodialysis,the OCM option provides an accurate tool for continuous on-line monitoring of urea clearance.

Objective To study the effect of methylmercury on the behavioral teratogenesis in filial r ats.Method Pregnant rats were injected intra-abdominally with 0 ,0.75,1.50,3.00 mg/kg methylmercury every other day,then early physiological fun ctions and behavioral functions of their filial rats were observed. Results The results indicated that when impregnated female ra ts were heavily exposed to methylmercury, early physiological development and be havioral development of their filial rats were retarded.Conclusion The methylmercury likely has the effect on behavioral teratogenesis of rats.

Objective To establish a rat model of pulmonary hypertension induced by left-to-right shunt and explore the influence of high pulmonary blood flow on pulmonary vascular collagen remodeling.Methods Abdominal aorta and inferior vena cava shunting was produced in rats. Pulmonary artery meanpressure (PAMP) of each rat was measured by using a right cardiac catheterization.Pulmonary artery collagen Ⅰ and Ⅲ were detected using immunohistochemisty.Results After 11 weeks of shunting the Qp/Qs was 3.3∶1.0,indicating a large shunt. Pulmonary artery mean pressure was increased as compared with controls[(23.0?0.9) mm Hg vs (15.7? 1.1) mm Hg,P
