Objective To evaluate the effect of community systemic management on quality of life in patients with hypertension.Methods A cross-sectional study was used to survey 224 patients with essential hypertension systemically managed in community and 205 non-management patients using the questionnaire including demographic information,behaviour,years of hypertension,treatment,Chinese version SF-36 short form of quality of life and the symptom distress checklist.Student-t test,?2-test,and covariance analysis was used in data analysis.Result The managed patients' mean score of knowledge(6.40?1.31)was significantly higher than that in non-managed patients'(5.02?1.82,t=8.82,P

Purpose:To observe the response and tolerance to the regimen of etoposide,folinic acid and fluorouracil (ELF) in advanced gastric cancer. Methods:Thirty two patients with advanced gastric cancer received chemotherapy of ELF regimen(VP 16 100 mg iv d 1—3 ,CF 100—300 mg iv d 1—3,5 FU 750 1 000 mg iv d 1—3 Results:The overall response rate was 37.5% (12/32) and complete response rate was 3.1% (1/31), the partial response rate was 33.4% (11/32). The main toxicity was myelosuppression and alopecia. Leukopenia was observed in 81.6% of the patients, but grade 3 and 4 in only 12.5%. Anemia and throbopenia was observed in 21.8% and 35.1% of the patients respectively, alopecia in 100%. Other side effects were uncommon. Conclusions:This study shows that the regimen of ELF is effective and tolerable for treatment of advanced gastric cancer. [

ObjectiveTo investigate the disruption of blood-brain barrier (BBB) after brain trauma in rats using IgG immunohistochemical staining.MethodsAn impact-acceleration head injury model was established with rats. Histological changes of rats' brains were observed by HE staining and light and electron microscopes at 1 h, 6 h, 24 h and 7 d after injury, and BBB permeability was analyzed semi-quantitatively by IgG immunohistochemical staining at the same time points.ResultsThe spot bleeding and brain edema was present in the damage region after brain trauma and endothelial cell damage and astrocyte swelling could be found under electron microscope. The extravasations of IgG was detected in the injured hemisphere of rats at 1 h, and achieved the peak at 6 h, remained a high level up to 24 h, and decreased at 7th d.ConclusionThe disruption of BBB function occurs after brain trauma in rats, and detection of IgG extravasations tested by immunohistochemical staining is a simple and sensitive way to investigate BBB permeability.

Objective To assess the effects of zinc protoporphyrin (ZnPP), an inhibitor of the heme oxygenase (HO), on the colonic interstitial cells of Cajal (ICC) of diabetic rats with colonic slow transit. Methods Diabetes mellitus (DM) model was induced by intraperitoneal injection of streptozotocin (STZ) in Sprague-Dawley rats. Twenty four successfully established DM rats were selected, and 16 healthy rats were served as controls. Six weeks later, gastrointestional (GI) dysfunction was observed by charcoal propulsion experiment in 8 DM rats and 8 controls. The rest rats in DM group were divided into 2 groups: DM rats intraperitoneal injected with PBS (n=8) or with 10 μmol/kg of ZnPP (n = 8) every other day for 3 weeks. The rats in control group (n = 8) were intraperitoneally injected with PBS. The levels of HO and c-kit (the special receptor of ICC) expression were detected by Western blotting. The distribution of ICC was observed by immunohistochemistry and the area of c-kit positive cells was counted. Results The GI propulsion rate in DM rats interfered with PBS was significantly declined compared to that in the controls (63.0%± 1.2% vs 71.8%±2.0%, P<0.05). But it was improved in DM rats interfered with ZnPP (72.5± 2.6%, P<0.05), which showed no significant differentee with that in control group (P>0.05). The expression of HO-1 in close and distant colon of DM rats interfered with ZnPP was decreased (P< 0.05). The expression of HO-2 in close colon and the area of c-kit positive cells of DM rats interfered with PBS was reduced compared with that in controls (P<0.05), but both were improved in DM rats interfered with ZnPP (P<0. 05). Conclusion Administration of ZnPP might be able to protect ICC by its blockage of HO-1 in DM rats with gastrointestinal dysfunction.

Objective To investigate the effect of chronic intermittent hypoxia (CIH) on myocardial tissue pathology,oxidative stress and apoptosis in rat fed a high-fat diet,and to explore the possible mechanism of CIH induced cardiomyocyte injury.Methods A total of 24 male Wistar rats were randomly divided into 3 groups (n=8 each).The control group was fed common rat forage,the high-fat group was fed high-fat forage,and the high-fat plus intermittent hypoxia group was fed high-fat forage combined with a 7h/d intermittent hypoxia treatment.The changes of myocardial tissue pathology and ultrastructure of cardiomyocyte,and the activities of apoptosis regulating factor cysteine-containing aspartate-specific proteases-3 (caspase-3) and oxidative stress marker myeloperoxidase (MPO) were observed in the 3 groups after 4 weeks of treatment.Results There were significant differences in the activities of caspase-3 and MPO among the three group (F=89.94,71.24,both P＝0.001).The activities of caspase-3 and MPO were lower in the control group than in the high-fat group and in high fat plus intermittent hypoxia group [(0.21±0.06) vs.(0.80±0.11),(1.15±0.21),(3.20±0.58) vs.(10.87±1.96),(13.17±2.22),P＜0.01].The activities of caspase-3 and MPO were higher in the high-fat plus intermittent hypoxia group than in the high fat group[(1.15±0.21) vs.(0.80±0.11),(13.17±2.22) vs.(10.87±1.96),P＜0.01].No abnormal findings in the structure of cardiomyocyte were observed in the control group,while multiple pathologic damages in cardiomyocyte were detected in the high-fat group,and more obvious injuries in the high-fat plus intermittent hypoxia group.Conclusions The pathologic damages to cardiomyocyte are more serious in high fat and intermittent hypoxia group than in the high-fat group.Apoptosis induced by oxidative stress may play an important role in the pathogenesis of these injuries.

This study was aimed to establish the classification method of Chinese herbal medicine based on feature parameters extracted from images of herbal transverse section, in order to explore the feasibility of automatic identi-fication method of herbal medicine. The extracted 26 parameters of 18 herbal medicine images by gray-level co-oc-currence matrix and grayscale gradient matrix were used as the basic data set. And the minimum covariance determi-nant (MCD) was used to delete the outliers. A total of 18 identification models were established using the native Bayes method and BP neural network methods. The results showed that the average correct rates of models were 90%. It was concluded the feasibility of using these models in the establishment of the automatic identification method of herbal medicines. It provided new technologies for the quantitative, scientific and objective identification of Chinese herbal medicine.
