Objective To investigate the different ability to produce H_(2)O_(2+) of the vaginal lactobacilli and their potential antagonism toward E.coli in ivtro.Then to select the potential lactobacilli strain to treat the female urogenital infection.Method To detect production of H_(2)O_(2) by measuring the blue matter in water solution with absorbtion spectrophotometry.The lactobacillus and E.coli were cultured together in solid culture medium,followed by the measurement of inhibition zone around the lactobacilli after 24 hour.Results We selected 4 strains of lactobacilli from vagina.L.acidophilus1 and L.paracasei3 are the stronger to produce H_(2)O_(2).The largest diameter of the ring of inhibition is shown around the lactobacilli acidophilus 1.Conclusion The lactobacilli acidophilus 1 and lactobacilli crispatus are the most potential strains as antagonist to E.coli and their antagonism depend not only on lacid or H_(2)O_(2).

Polo-like kinase 1 (PLK1) is a highly conserved serine/threonine protein kinase that has attracted research attention be-cause it plays a critical role in mitosis regulation. PLK1 is overexpressed in 80%of human tumors, which indicates a poor prognosis in most tumors. PLK1 is one of the most promising targets for antitumor therapy because it is upregulated in castrate-resistant prostate can-cer (CRPC). This review focused on the basic structure and function of PLK1, the relationship between PLK1 and CRPC occurrence and progression, and CRPC treatment by inhibiting PLK1. This study provides a theoretical basis for the targeted molecular therapy of CRPC.

To investigate the psychological difference in abdominal aortic aneurysm patients before and after operation and its influence on life quality, 24 patients who can understand and complete the questionnaire were enrolled in the study, the inquiry was performed after admission and discharge with the standard SCL 90 table. The results showed that the general conditions, depression, anxiety, compulsive symptoms and fear of the patients had marked differences before and after operation. It is concluded that operation of abdominal aortic aneurysm can not only prevent the rupture of aneurysm but also relieve the patients′ psychological pressuer and improve their life quality.

Objective To explore the impact of social support and perceived stigma on depression for people living with HIV/AIDS. Methods A total of 114 patients recruited into our study. Date were collected by Self-rating Depression Scale (SDS), Social Supporting Rating Scale (SRSS) and Berger HIV Stigma Scale (BHSS) for patients. Analysis of Moment Structures (AMOS) version 7.0 software was used to conduct the path analysis. Results The total score of patients′depression, SRSS and BHSS were (52.22± 10.28), (29.09±5.98), (109.02±14.59) points, and there was correlation between the three (r=0.425-0.676, P<0.05). Social support revealed direct effects on depression and affected depression indirectly via BHSS.The paths′ total coefficients was-0.47. BHSS as intermediary variable between social support and depression, the paths′ total coefficients was 0.64. Conclusions The level of depression, SRSS and BHSS were not fine for HIV/AIDS. Depression are directly affected by SRSS and BHSS, BHSS has a greater moderating effect on these relationships. Interventions developed on the basis of influencing factors of depression should be applied to improve patients′depression status.

Bacterial colonization is a sign of bacterial infection in the hospital, and the bacterial colonization rate indicates the risk of bacteria infection. Newborn infection happen easily in the hospital. In recent years, sereral researches indicate that vaginal delivery, breastfeeding and probiotics usage and so on can lower the probability of intestinal pathogenic bacteria colonization, which can lower the probability of neonatal enterogenous infection. Therefore, there are many factors that can effect on newborn intestinal bacteria colonization, and because experimental conditions are limitated, so we have many problems to solove in the future.

Objective To determine whether platelet activation is associated with active ulcerative colitis (UC). Methods Platelet aggregability was assessed by means of SH 93 intelligent blood aggregation and coagulation tester; P selectin and thromboxane B 2 (TXB 2) were detected by means of ELISA method in patients with UC as well as in controls, including healthy volunteers and patients with irritable bowel syndrome (IBS). Colonoscopy and biopsy were performed in 43 patients with UC. Results Increased circulating platelet aggregability was detected in active ulcerative colitis compared with IBS and healthy controls ( P

Objective To summarize the basic process to create epidemiological surveillance system. Methods First, make use of the system science, information science, control science and related disciplines as theory, use deductive reasoning to get the basic process of creating epidemiological surveillance system. Then, choose 50 existing epidemiological surveillance system to study, choose the characteristics of epidemiological surveillance system as the fundaction, use inductive reasoning to complete the basic process. Results The basic process of creating the epidemiological surveillance system include: system analysis, set up the logic model of the system, system design, system implementation, system evaluation, system improving. Conclusions Epidemiological surveillance system are indispensable aspects, they should be well integrated in order to ensure the effectiveness of created epidemiological surveillance system.

OBJECTIVE:To analyze the cost of three schemes in treatment of unstable angina pectoris METHODS:88 patients with unstable angina pectoris were divided into three groups:group Ⅰ was given isosorbide,asprin,nifedipine and nitroglycerin;group Ⅱ was given isosorbide,asprin,nifedipine,nitroglycerin and red sage injection and group Ⅲ was given isosorbide,asprin,nifedipine,nitroglycerin and puerarin;then using pharmacoeconomic method,cost-effectiveness analysis was carried out RESULTS:The efficacy in the group Ⅱ and group Ⅲ was higher than that in group Ⅰ(P0 05),and the E/C(effectiveness/cost) of the three groups were 15 98,18 02 and 33 40 respectively Compared with group Ⅰ,?C/?E of group Ⅱ and Ⅲ were 24 66,83 90 respectively;Compared with group Ⅱ,?C/?E of group Ⅲ was 643 60 CONCLUSION:The scheme for group Ⅱ is the best one

OBJECTIVE:To find out an effective way to control the unreasonable increase of drug expenses.METHODS:To analyse and evaluate the role of pharmacoeconomic research in suppression of unreasonable increase of drug expenses.RESULTS:The best therapeutic scheme could be found out by pharmacoeconomic research through the way of determination of the cost and efficacy of pharmacotherapy,and the unreasonable increase of drug expenses could also be cut down in5aspects.CONCLUSION:Pharmacoeconomic research is a practical and feasible way to control unreasonable increase of medical expenses.
