OBJECTIVE:To study the effect of Hordeum vulgare on hormone level in male mice.METHODS:Male mature mice(5～6 months) were treated with Hordeum vulgare decoction 1 mL(equivalent to 0.5 g?mL-1 crude drug) bid for 14 consecutive days.Follicle-stimulating hormone(FSH),luteinizing hormone(LH),estradiol(E2) and testosterone(T) in blood were monitored.RESULTS:In Hordeum vulgare group compared normal control,serum E2 increased significantly,serum level of testosterone decreased significantly,while FSH and LH levels remained stable.CONCLUSION:Hordeum vulgare can influence the hormone level in male mice by influencing the gonad axis of the mice.

0.05); the effective rates in rest pain in the two groups were 41.25% and 57.97%,respectively(P

Literatures available was reviewed on the thrombosis and mechanism of new antithrombotic agents.The pathophysiology of the thrombosis involves dysfunction of endothelium and cell adhesion.The new antithrombotic drugs include factor Ⅹa inhibitors, GPⅡb/Ⅲa receptor blocking agents and the drugs modulating the function of endothelium.

OBJECTIVE To study the staphylococcus infection and the drug resistance among the outpetients and the inpatients, and to provide information for the clinical treatment.METHODS To cultivate and isolate bacteria according to the Clinical Laboratory Operation Regulation.Bacteria were identified with the automated analyzer VITEK-60.made by Bio-Merieux Company in France.The drug susceptibility was one with the method of single split agar diffusion.RESULTS Totally 159 strains of Staphylococcus were isolated from the outpatients,(46.1%) of which were MRSA.Most of the infection were caused through genital tract;390 strains of(Staphylococcus) were(isolated) from the inpatients,87.1% of which were MRSA.Most of the infection were caused through respiratory tract.Most of MSSA resisted to penicillin,but MRSA were sensitive to vancomycin and(teicoplanin.) (CONCLUSIONS) Preventing the spread of the MRSA is very important to the control of the nosocomial(infection).As far as the infective situation,most of the outpatients are infected through genital tract;while most of the inpatients are infected through respiratory tract.As far as the drug susceptibility,vancomycin is the best antibiotics,the next is teicoplanin.It is necessary to use combined drugs for the MRSA infection.

Objective: To probe into the relationship between changes of sex hormone levels and TCM syndrome differentiation in climacteric women.Methods: According to TCM syndrome differentiation,55 cases of women in menopause were divided into three groups: kidney yang deficiency,kidney yin deficiency and the normal;the correlation between the three types and E2,FSH and LH was explored by statistical methods,and then they were compared with procreative women.Results: In all the 55 cases,kidney yin deficiency covered 70.90%,kidney yang deficiency covered 16.36%,the normal covered 12.72%;changes of E2 correlated positively with symptom scores of kidney yang deficiency and kidney yin deficiency;changes of FSH and LH correlate negatively with that of kidney yang deficiency and kidney yin deficiency.And they all correlated closely with menopause.Conclusion: the main syndrome type of climacteric women was kidney yin deficiency;E2↓,FSH↑ and LH↑ was expression of physiological kidney deficiency of climacteric women.

Objective To study the influence of pine-seed oil upon body weight,blood lipid and lipid peroxidation of mice fed on high fat feed.Method The mice were fed by high fat feed(80% basal feed added 20% lard,HF) and HF added pine-seed oil(80% high fat feed added 20% pine-seed oil,SHF).At 45 d and 90 d,the body fat content,blood lipid level,and malonyldehyde(MDA),lipofusin(LP),catalase(CAT),superoxide dismutase(SOD) and glutathione peroxidase(GSH-Px) of brain and liver homogenate were measured respectively.Results Pine-seed oil could reduce the body weight serum triglyceride(TG),total cholesterol(TC),low density lipoprotein-cholesterol(LDL-C) content,but increase high density lipoprotein-cholesterol(HDL-C) of the mice fed by HF.It suggested that pine-seed oil had definite effect on regulating blood lipid.Compared with normal control(NC) group,the activities of CAT、T-SOD、GSH-Px of brain and liver in HF group were remarkably lower,but MDA and LP remarkably higher.It suggested that HF could promote lipid peroxidation in brain and liver of mice.Compared with HF group,the activites of CAT,T-SOD and GSH-Px of brain and liver in SHF group were remarkably higher,but MDA remarkably lower.Conclusion Pine-seed oil can reduce the body weight,blood lipid,and lipid peroxidation of mice fed by HF.

Objective To find out the status of nosocomial infection management in hemodialysis sections, in order to encourage their continuous quality improvement and standardize their management Methods 41 hemodialysis sections with (≥) 3 dialyzers and independent operation were chosen for investigation. On-site investigation and environmental microbiology monitoring combined. Results The higher the level of the hospital, the better the nosocomial infection control in its implementation of the infection control measures. In terms of rules and regulations, incompliant secondary hospitals and private hospitals accounted for 56. 2% of hospitals of the same ranking; in terms of layout and processes, 75% are found incompliant; and various defects are found in the dialyzer reuse management and disinfection in tertiary and lower hospitals. As to hand hygiene of the staff, the incompliance rate is over 55%. As indicated in the results of microbial environment monitoring, the compliance rate of dialysis water is over 90%, that of dialysate is 78.6% ～ 86.2%, and that of hand disinfection is 56.6%～78.6%.Conclusion It is imperative to strengthen the supervision of secondary hospitals and private hospitals,and to train their staff in the knowledge of hand hygiene and nosocomial infection in hemodialysis rooms.Hospitals found with poor infection management will be encouraged to take issue-specific actions for rectification.

Aim To establish and evaluate a mouse model of my-ocardial fibrosis by hypodermic injection of isoprenaline. Meth-ods Kunming mice were randomly divided into 2 groups, namely, the myocardial fibrosis model group and the control group, 10 mice in each group. The mice in the model group were given isoprenaline 5 mg · kg-1 by hypodermic injection. From the following day, the dose of isoprenaline was reduced to 2. 5 mg·kg-1 , and lasted for 30 days. The mice in the control group were treated with the physiological saline in the same way. Final-ly, heart weight was then weighed and the cardiac weight index (CWI) was calculated. Hydroxyproline (Hydro) level in myo-cardium was determined by a colorimetric method. HE and Mas-son’s trichrome staining were used to estimate the extent of myo-cardial fibrosis and calculate the collagen volume fraction ( CVF) . RT-PCR was used to measure the myocardial Collagen I mRNA expression. Results Compared with the control group, the CWI and Hydro content in the myocardial tissues in the model group were increased(P<0.01). The content of col-lagen in the myocardial tissues and the CVF were increased obvi-ously(P<0.01). The RT-PCR results showed that the left ven-tricle Collagen I mRNA expression in the model group increased obviously( P<0.01 ) . Conclusion Isoprenaline-induced myo-cardial fibrosis model has been established and the method is very simple, economic and reliable.
