OBJECTIVE To understand the susceptibility to antituberculous agents for patients with primary and acquired drug resistance of Mycobacterium tuberculosis. METHODS M. tuberculosis positive sputum samples were collected from Jun to Dec 2006. Ameliorative Lowenstein-Jensen culture medium was used to detect bacillus-positive specimen of pulmonary tuberculosis by typing using PNB and TCH. Totally 217 samples were confirmedtobe positive by culturing. Drug susceptibility test against streptomycin (SM),isoniazid (INH),rifampicin (RFP) and ethambutol (EMB) was conducted. RESULTS The total drug resistance rate was 65.90%,the initial drug resistance rate was 39.81% and the initial multi-drug resistance rate was 16.67% ;the acquired drug resistance rate was 91.74%,and the acquired multi-drug resistance rate was 74.31%. The main causes of drug resistance were irregularit of treatment at beginning and preterm stop of the freatment course by patients own selves,which accounted for 71.6%. CONCLUSIONS The drug resistance of M. tuberculosis is caused by irregular treatment,so the key to prevent and control drug resistance is rational and whole-course treatment.

Objective To investigate the risk factors of incidence of hypertensive disorder complicating pregnancy(HDCP)and provide reference for prevention and treatment of HDCP.Methods The clinical information of 2 217 cases of maternal delivery were retrospectively analyzed;The relevant social factors and obstetric factors of HDCP were analyzed.Results 186 cases of HDCP occurred in 2 217 cases of maternal,the incidence rate of HDCP was 8.4%.The single-factor analysis showed that the place of residence.prenatal system checks and parity had certain degree of contact with incidence of HDCP(χ2=11.2331,10.6781,5.4456,all P＜0.05),and the age,abortion history and parity had no significant correlation with incidence of HDCP(χ2=4.9201,3.0134,1.7301,all P＞0.05).Multivariate Logistic regression analysis showed that the rural living and no prenatal system check were risk factors of incidence of HDCP.Conclusion The maternal of rural living and no prenatal system check were the high-risk population of HDCP,and emphasis assessment and reasonable control these factors could reduce the incidence of HDCP.

Objective To investigate the effect of hysterectomy and uterine arterial embolization on the function of ovary.Methods The serum concentrations of estrin(E2), progestogen(P),fouicule-stimulating hormone(FSH),luteotropic hormone(LH) and prolaction(PRL) were measured in 18 patients undergone hysterectomy (group Ⅰ),15 patients undergone uterine arterial emboliation(group Ⅱ) and 30normal women (group Ⅲ or control group).These five hormones were compared in each group.Results The serum concentrations of E2 and P in the group Ⅰ were lower than that in group Ⅲ, there was significant difference between them.The serum concentrations of E2 and P in group Ⅱ and group Ⅲ was no significant difference.Conclusion Hysterectomy has significant effects on the function of ovary,while uterine arterial embolization has not.

The in vitro modulation effect of insulin on DNA and IL-2 production of spleen lymphocytes in diabetic mice were studied. The results suggest that the DNA and IL-2 production of the lymphoc-ytes are significantly inhibited in the mice. When suspend the lymphocytes to the culture medium containing insulin, the DNA and IL -2 production of the lymphocytes are remarkably increased. Therefore, insulin is an important immunoregulation hormone.

Objective: To plan the future for the establishment and development of health econometrics in China. Methods: To analyze the main current situation of the research on domestic and oversea health econometrics, and to look into the prospective future of its application field of public health in China. Results: Overseas studies on health economics have been relatively mature and extended to generate health econometrics as the independent discipline. However, the research on health economics in China is lagging, and on health econometrics even vacant. Conclusion: The results from foreign studies have revealed that this new discipline plays a unique and significant role in medical health research. Health econometrics occupies broad application prospect in the field of public health in China, which should be paid more attention and support.

Objective:To study the epidemiology of inpatients with fractures and discuss its effect on health education.Methods:Therer were 6290 inpatie nts with fracture investigated retrospectively.FoxPro and SPSS were used for statistical analysis.Results:The mean age of the patients was 41.03±20.05 years.The fraction male to female patients was 2.39:1.The mean hospitalized days were 24.11±22.73 days (±s).A majority(63.5%) of the patients were admitted to the hospital by emerg ency.Fractures in 15 parts accounted for 70% of total fractures in 6 hospital, 7 of which accounted for more than 50% of total fractures in each hospital.Discussion:Health education should be carried out according to risk factors as well as age and gender.The devel opment of the model,which combines prevention,first-aid and rehabilitation,is t he trend of health education for fractures.The basic knowledge of fractures in these 15 parts should be learned by orthopedic nurses.Patient education should be carried out individually.The hospital's situation should also be considered.

Objective To observe the influence of systemic and intraperitoneal hyperthermic perfusion chemotherapy on serum vascular endothelial growth factor(VEGF) and human epididymis protein 4 (HE4) in patients with ovarian cancer.Methods 116 cases with ovarian cancer were,randomly divided into the observation group and the control group according to the number table,58 cases in each group.The observation group was given systemic and intraperitoneal hyperthermic perfusion chemotherapy,and the control group received systemic chemotherapy,they all completed a total of two cycles of chemotherapy.Serum VEGF and HE4 were measured before and after chemotherapy.Results The total effective rate of the observation group was 74.1％,and that was 56.9％ of the control group,the difference was significant (x2 =4.290,P ＜ 0.05).After chemotherapy,the serum VEGF and HE4 were signifi cantly decreased in two groups,and compared with the control group,the observation group decreased more significantly(t =3.180,2.725,all P ＜ 0.05).Conclusion Systemic and intraperitoneal hyperthermic perfusion chemotherapy in treatment of patients with ovarian cancer can significantly reduce serum VEGF and HE4.
