Objective To compare the effects of Dan Shen Extract F(DSEF) and cimetidine (CI) on reperfusion injury in gastric antrum. Methods Nineteen Wistar rats were randomly allocated to receiving intravenously normal saline (group NS, n = 7), DSEF 1g/100g wt (group DSEF, n = 6) or CI 6.5mg/ 100g wt (group CI, n = 6 ) respectively. Model of hemorrhagic shock roperfusion injury was produced by Itch method. The index and depth of gastric mucosal lesion, prostaglandins content and intracellular calcium content of gastric antrum mucosa were measured. Results (1 ) As compared with those in group NS, the index and depth of gastric mucosal lesion (grade 2, 3) decreased significantly in group DSEF and CI (P 0.05 ). (3 ) The intracellular calcium content in group DSEF and CI was markedly lower than that in group NS (P 0. 05). Conclusions Both DSEF and CI can prevent largely the reperfusion injury in gastric antrum mucosa through different mechanisms, with DSEF having stronger potency.

Objective To observe the feasibility of combining dezocine with fentanyl in the application of single integral high in‐tensity focused ultrasound(HIFU)ablation of uterine fibroids .Methods One hundred and sixty patients with uterine fibroids trea‐ted by HIFU under conscious sedation were randomly divided into 2 groups(n=80):group A with treatment combined fentanyl and midazolam and group B treated with combined dezocine ,fentanyl and midazolam .Analgesic effect was evaluated with visual analog scale (VAS) .Variation of patients′vital signs (blood pressure ,heart rate ,electrocardiogram ,oxygen saturation) ,pain scores ,com‐fort scores ,sedation scores ,analgesic consumption and side effects were recorded before treatment (T0 ) ,during drug delivery (T1 ) , at the beginning of the treatment(T2 ) ,30 minutes after drug delivery (T3 ) ,at the end of the treatment(T4 ) ,2 hours after treatment (T5 ) ,4 hours after treatment (T6 ) ,8 hours after treatment (T7 )and 24 hours after treatment(T8 ) .Results Both groups showed reliable analgesic effects and vital signs of each time point were stable .VAS scores and Ramsay scores of group A were higher than those of group B ,but there was no statistical difference (P>0 .05) .Three patients in group A showed dysuria and relieved after symptomatic treatment .No respiratory depression occurred in both groups .But compared to group A ,the incidence of the analgesic side effects of group B was significantly lower and patients satisfaction was significantly higher(P<0 .05) .Conclusion The analge‐sic effects of dezocine combined with fentanyl are reliable in HIFU ablation of uterine fibroids with fewer side effects ,and could be worthy to be promoted in clinical use .

OBJECTIVE To provide current tendency of viral transmission by test-negative blood components changing among blood donors and to improve the safety of blood for transfusion.METHODS The test data of 1 608 816 blood donors in Beijing Red Cross Blood Center from 2001 to 2008 were analyzed.RESULTS Before voluntary blood donation,the positive rate of anti-HCV was 0.16%,that of anti-HIV was 0.005% and that of anti-TP was 0.15%.After voluntary blood donation,positive rate of these components increased,there were 0.45%,0.017% and 0.48%,respectively,but the positive rate of HBsAg and ALT was decreased.After voluntary blood donation,the positive rate of HBsAg,anti-HCV,anti-HIV and anti-TP were elevated,that of ALT was decreased in greatly.CONCLUSIONS As the increasing risk of viral transmission disease,it is more important for blood safety to screen volunteer blood donors.

Objective To investigate the effects of penehyclidine hydrochloride on blood-brain barrier in a rat model of cardiopulmonary bypass ( CPB) . Methods Sixty adult male SD rats, aged 4-6 months, weighing 320- 370 g, were randomly divided into 5 groups ( n = 12 each) : sham operation group (group S), CPB group, and low-, median- and high-dose penehyclidine hydrochloride groups (groups LP, MP and HP). The animals were anesthetized with intraperitoneal 10% chloral hydrate 350 mg/kg, intubated and mechanically ventilated. The femoral and jugular arteries and jugular vein were cannulated. CPB was performed for 60 min. Penehyclidine hydrochloride 0.2, 0.6 and 2.0 mg/kg were added to the priming solution in groups LP, MP and HP respectively, while the equal volume of normal saline was added in group CPB. Evans blue was injected via femoral vein at 1 h before the animals were sacrificed. Six rats in each group were sacrificed, their brains immediately removed and the hippocampi isolated for determination of Evans blue content. The other rats were sacrificed and the hippocampi isolated to determine the water content and observe the ultrastructure of blood-brain barrier. Results Compared with group S, the Evans blue content and water content were significantly increased in the other groups ( P ＜ 0.05) . Compared with groups CPB and LP, the Evans blue content and water content were significantly decreased in groups MP and HP ( P ＜ 0.05) . The Evans blue content was significantly lower in group HP than in group MP ( P ＜ 0.05). The CPB-induced changes were significantly attenuated in groups MP and HP compared with groups CPB and LP. Conclusion Penehyclidine hydrochloride can protect blood-brain barrier against the CPB-induced injury and the effect is related to the dose.
