Objective To monitor the constituents and resistant tendency of bacterial pathogens isolated from diarrheal patients in our hospital form 1994 to 2005 to offer the basis for guiding epidemiologic study,vaccination research and clinical treatment. Methods Enteric pathogenic bacteria were cultured and identified to species,group and serotype with biochemical and serologic methods and the susceptibility of bacteria to antimicrobial agents were tested. Results Enteric pathogenic bacteria were isolated predominantly in male patients and mainly in children and youngsters. It reached a peak from July to September every year. Shigella spp.(75.11%) was the most frequendy isolated pathogens and followed by Vibrio spp.(12.7%),Salmonella spp.(6.28%),Aeromonas spp.(4.43%) and Escherichia coli(1.25%).During the period from 1994 to 2005,diarrheal pathogens had a trend of decrease especially Shigella spp.and Salmonella spp.. Of the 6329 isolates of Shigella spp., 75.62% was S. flexneri and S.soanei,S.dysenteriae and S. boydii constituted 23.98%,0.22% and 0.01% respectively.The sensitivity of different species,group or serotype to different antimicrobial agents was not the same.S.flexneri and Aeromonas spp. were highly resistant to most of antibiotics. However, S.sonnei and Vibrio spp.had good susceptibility to antibiotics tested except trimethoprim/sulfamethoxazole and ampicillin. Conclusion There are many species and serotypes of enteric pathogenic bacteria causing infective diarrhea and the distribution changes gradually in Beijing. The resistance rate of enteric pathogenic bacteria to antibiotics is not the same in different species and serotypes.so strict surveillance iS always needed.

AIM To determine the concentration of paeonol in the bulk drug and injection, a method of reversed-phase high performance liquid chromatography (RP-HPLC) was developed. METHODS Lichrospher C_ 18 column(4.6 mm?250 mm, 5 ?m)was used with methanol-acetonitrile-water(30∶40∶30)as mobile phase at a flow rate of 0.8 ml?min -1 . 20 ?l of sample was injected into the C_ 18 column where the temperature was 25℃. The detection wavelength was 274 nm. RESULTS The linear regression equation for paeonol was = 3 772.525 8 X- 0.747 4 (r = 1.000 0, n =5) under the linearity range from 0.02 mg?L -1 to 25.60 mg?L -1 . The average recovery was 99.87%. The relative standard deviations of the intra-day and inter-day were less than 4%. CONCLUSION The method is simple and rapid, which may be used for the determination of paeonol and its preparation for different purpose.

Objective To evaluate the effect of health education on the old male patients with primary hypertension.Methods 120 old male patients with primary hypertension were randomly selected from the whole group and educated with health knowledge related to blood hypertension, and the changes of life style and blood pressure after health education were recorded.Results Most of the patients changed their unhealthy life style. Among these patients, more than 80% were able to have a stable emotion, regular daily life, stop smoking and less drinking, there were 66% cases with a healthy diet. The systolic pressure of the patients declined significantly after health education (P<0.01).Conclusion The health education is an efficient way to control hypertension in the official-service outpatient department.

Objective:To study the expression of caveolin-1 in colorectal adenocarcinoma tissues and its correlation with microlymphatic vessel density (LMVD), and to investigate the clinical pathological prognostic significance of caveolin-1 and LMVD in patients with colorectal cancer.Methods:The expression of caveolin-1 and LMVD in 45 specimens of normal colorectal tissues, and 90 specimens of colorectal adenocarcinoma tissues were detected by immunohistochemistry technique. The correlation between their expression and the clinicopathologic features was analyzed. Muhivariable Cox regression was used to analyze the association between the laboratory indices and overall survival time.Results:The positive rates of caveolin-1 in colorectal adenocarcinoma tissues were significantly higher than those in normal colorectal tissues (P<0.01). LMVD in colorectal adenocarcinoma tissues were significantly higher than those in normal colorectal tissues (P<0.01). Mean LMVD in group with caveolin-1 positive was significantly higher than in that with caveolin-1 negative. The median survival time was 26.7 months. Cox regression analysis showed that the caveolin-1 expression, invation depth, lymph nodemetastasis, TNM stage, liver metastasis and LMVD were independent risk factors of overall survival time of patients with colorectal carcinoma. Conclusions:Caveolin-1 may contribute to the lymphangiogenesis in the tumor. During the occurrence and development of colorectal adenocarcinoma, there is a close relationship between the expression of caveolin-1 and lymphatic microvessel of tumor. Caveolin-1 expression and microlymphatic vessel density are significant prognostic value of colorectal carcinoma.
