Comparison of efficacy and safety of daily oral L-arginine and PDE5Is alone or combination in treating erectile dysfunction: A systematic review and meta-analysis of randomised controlled trials

The meta-analysis was performed to assess the efficacy and safety of daily oral L-arginine and phosphodiesterase type 5 inhibitors (PDE5Is) alone or combination in treating patients with erectile dysfunction (ED). We performed a search of randomised controlled trials in the following databases: PubMed, EMBASE and Cochrane Library databases. Four articles including 373 patients were studied. Erectile functions were significantly improved in three therapy groups compared with baseline. Patients who received the combination of L-arginine and PDE5Is showed significant improvement compared to those treated with L-arginine and PDE5Is alone, as assessed by sexual function index (p <0.00001 and p =0.005, respectively) and total testosterone (p <0.00001 and p =0.0007, respectively). Furthermore, patients who treated with PDE5Is alone exhibited the better efficacy than those treated with L-arginine alone in respects of sexual function index (p <0.00001) and total testosterone (p =0.0001). However, the combination of L-arginine and PDE5Is had no obvious difference relative to PDE5Is alone in terms of various adverse events (AEs). Conclusively, compared with monotherapy, the combination of L-arginine and PDE5Is showed a greater improvement of sexual function and total testosterone, and did not significantly increase the AEs. Besides, PDE5Is alone revealed a better effect than those treated with L-arginine alone for patients with ED.

氧化铝颗粒大小对PEO—NaSCN络合物电导率的影响

研究分散第二相Ａｌ２Ｏ３的含量及颗粒大小对ＰＥＯ－ＮａＳＣＮ络合物电导的影响,结果表明：当颗粒度为０．７μｍ时,电导率比纯ＰＥＯ－ＮａＳＣＮ提高了一个半数量级。颗粒度较大时,电导率均比纯ＰＥＯ－ＮａＳＣＮ低,并在ｗＡｌ２Ｏ３＝０．２５时,存在电导率最大的峰值。     

抗柯萨奇B中药胶囊治疗病毒性心肌炎的临床疗效评价

目的观察抗柯萨奇B心肌炎胶囊(ACCM)治疗病毒性心肌炎(VM)的临床疗效.方法将120例VM患者随机分成ACCM组(用ACCM治疗,60例)和对照组(西药常规治疗,60例),进行对比观察.结果ACCM组总有效率85%,明显优于对照组的57%(P<0.05).治疗后ACCM组的心悸、反复感冒、胸闷、胸痛、气短、乏力、头晕等症状的恢复明显优于对照组.结论ACCM是治疗VM的一种高效、价廉及使用方便的中药制剂, 无明显不良反应.     

进口化学药品说明书的基本要素

药品说明书是药品获批准上市后的重要证明文件之一，是对被批准的适应症、用法、用量等有关用药重要信息的详细说明，是指导医患用药的关键依据。在《中华人民共和国药品管理法》、《药品注册管理办法》（试行）以及国家食品药品监督管理局局23号令等法律、法规和条例中，对药品说明书及相关内容明确了其要求和责任等，这对认识说明书的作用和地位，并且对其进行制订和核准都起着重要的指导作用。     

COX-2、Survivin蛋白在卵巢上皮性癌中的表达及与临床病理因素的关系

目的探讨卵巢上皮性癌组织中环氧合酶2（COX-2）与Survivin的表达以及与临床病理因素的关系。方法采用免疫组化Elivision染色法检测COX-2、Survivin蛋白在60例卵巢上皮性癌组织、20例正常卵巢、20例良性卵巢上皮性肿瘤及20例交界性卵巢上皮性肿瘤中的表达。结果COX-2、Survivin蛋白在正常卵巢、良性卵巢上皮性肿瘤、交界性卵巢上皮性肿瘤组织及卵巢上皮性癌组织中的表达差异有高度显著性（P〈O．05）。COX-2表达与卵巢上皮性癌患者盆腹腔淋巴结有无转移呈显著相关性（P〈O．05）。Survivin基因表达与卵巢上皮性癌的病理类型有相关性（P〈O．05）、Survivin基因表达与淋巴结转移有显著相关性（P〈O．05）。结论COX-2、Survivin蛋白在卵巢上皮性癌中高表达，并在卵巢上皮性癌的发生、发展中起着重要作用，说明卵巢上皮性癌的发生非单一基因作用，而是多基因协同作用。

Target nursing care on anxiety and depression in patients with gallbladder cancer during perioperative period

Background:This study retrospectively investigated the effects of target nursing care (TNC) on anxiety and depression in patients with gallbladder cancer (GBC) during the perioperative period.Methods:This retrospective study analyzed the data of 80 patients with GBC during perioperative period. These records were divided into an intervention group (n = 40) or a control group (n = 40). All 80 patient records in both groups were administered routine nursing care (RNC). The patients in the intervention group also underwent TNC. The primary outcomes were depression (measured using the Hamilton Depression Scale, HAMD) and anxiety (assessed using the Hamilton Anxiety Scale, HAMA). The secondary outcomes were quality of life (assessed using the 36-Item Short Form Health Survey, SF-36) and adverse events. We collected and analyzed the outcome data before and after treatment.Results:After treatment, patients in the intervention group showed more promising effects on depression (HAMD, P < .01) and anxiety (HAMA, P < .01) than those in the control group did. However, there were no significant differences in the quality of life before and after treatment. No TNC- or RNC-associated adverse events were reported in patient records.Conclusion:This study found that TNC was more effective than RNC in relieving depression and anxiety. Future studies should be conducted to validate the present findings.
