Objective To establish the animal model with stress ulcer(SU) and probe the relationship between the gastric mucosal injury and lasting stress time,the dynamic structural changes of pH of gastric juice.Methods Twenty-four SD young rats were randomly divided into 4 groups:control group,45 min(groupⅠ),90 min(groupⅡ),3 h(groupⅢ)groups under water immersion restraint stress(WRS).The change of gastric mucosal ulcer index(UI),pH of gastric juice were observed.Results Acute gastric mucosal damage was induced by WRS,with the WRS time prolonged,UI increased gradually and pH of gastric juice remarkably decreased in experimental rats.UI was positively rela-ted with stress time(r=0.957 P

AIM: To investigate the role of retinal pigment epithelium (RPE) in the growth of Müller cells using a co-culture system in vitro . METHODS: Müller cells were cocultured with RPE cells under both normoxic and hypoxic conditions in Transwell chamber culture system. Müller cell proliferation was evaluated by MTT assay. The number of cells which migrate through micropores and stay on the outer bottom side of insert systems were observed and counted. RESULTS: The activities of proliferation and migration of Müller cells when cocultured with RPE cells were significantly higher than those of the Müller cells when cultured alone at all time points under both normoxic and hypoxic conditions. However, for both the coculture and control groups, there is no significant difference between the measurements at 3 and 6 hours. CONCLUSION: Evidence suggests that RPE, when co-cultured with Müller cells, can stimulate migration and proliferation of Müller cells under both hypoxic and normoxic conditions in a time-dependent manner; how-ever, there is no evidence to support the synergetic interaction of RPE and Müller cells co-cultured under hypoxic conditions.

OBJECTIVE:To analyze the rules and characteristics of adverse drug reactions(ADR)induced by Shuxuetong in-jection,and provide reference for clinical rational drug use. METHODS:ADR cases induced by Shuxuetong injection in Beijing collected by national ADR monitoring center in 2012 were retrieved,and 35 cases of the ADR were statistically analyzed. RE-SULTS:ADR induced by Shuxuetong injection had relatively high incidence in elder over 60 years old(68.57%);ADR might oc-curred after 5 min with off-label use and it mainly occured after 10 min-2 h(40.00%);clinical manifestations were mainly systemic damage and nervous system damage,and all patients were returned to normal after symptomatic treatment except one with unclear outcome. CONCLUSIONS:ADR induced by Shuxuetong injection is related to age and dosage. Clinical medication should be strict-ly in accordance with the instructions,strengthen medication monitoring and reduce incidence of ADR to ensure medication safety.

Background More and more evidences suggest that the interaction of retinal progression of retinal diseases.Objective Present study was to investigate the primarily cultured and digested using explant culture method and trypsas acidic protein(GFAP) staining,S-100 staining and cytokine-18 staining co-cultured under the normoxia and hypoxia using transwell chamber,and the proliferation and migration of cultured RPE cells were examined using MTT and compared with only RPE cells cultured group at 3, 6, 24 and 48 hours.Results Over 90% of primarily cultured RPE cells showed the positive response for S-100.The proliferation and migration of RPE cells were significantly increased in hypoxia condition compared with normoxia condition (P＜0.01).In hypoxia group,amount of proliferation and migration of RPE cells in co-culture group were higher than the only RPE cells cultured group(P＜0.01).Conclusion Hypoxia appear to aggravate the proliferation and migration of RPE cells under the hypoxia status.

Objective To study the feasibility and safety of interventional closure for the treatment of infant’s perimembranous ventricle septal defect (PmVSD). Methods During the period from Jan. 2012 to Jan. 2013, a total of 229 single PmVSD infants less than three years of age were admitted to authors ’ hospital. The infantile patients were divided into intervention group (n = 88) and surgery group (n = 141). Patients in the intervention group underwent interventional closure procedure , while patients in the surgery group received conventional cardiac surgery. The operation success rate , the main and minor complication rates, the operation time, the postoperative hospitalization days, the incidence of postoperative pulmonary infection and the medical cost were recorded , and the results were compared between the two groups. Results No statistically significant differences in the operation success rate, the main complication rate, the postoperative hospitalization days and the medical cost existed between the two groups (P > 0.05). But the minor complication rate and the operation time of the intervention group were better than those of the surgery group. In the surgery group, the minor complication was mainly the respiratory infection, which was manifested as higher leukocyte count, higher C-reactive protein level, higher myocardial damage marker level as well as higher vasoactive drug scores in 24 hours after the operation , and the above items were significantly higher than those in the intervention group. Conclusion For the treatment of infant’s perimembranous ventricle septal defect, percutaneous transcatheter closure is clinically feasible. This technique is safe and reliable with obvious advantages when the indication is strictly observed and the procedure is carefully manipulated. This treatment can partly replace the conventional surgery.
