中风发病后6—9月的生命质量

目的 比较发病后6－9月的中风患者与正常对照的健康差异,以明确针对中风患者的社区卫生服务应着手解决的健康问题。方法 对150例中风后6－9月的患者及按照性别、年龄、居住环境进行1：1配对的正常对照,采用SF－36进行健康自评,比较不同领域的健康状况。结果 患者生命质量在躯体功能、生理性角色功能受限、 社会功能、活力4个领域（P＜0．01）随年龄的增加而降低。男性生命质量在总体健康（P＝0．017）、躯体功能（P＝0．015）、活力和精神健康（P＜0．01）等4个领域好于女性。患者与对照比较,除了疼痛（P＝0．289）领域外,患者生命质量的各个领域均差于对照（P≤0．001）。结论 患者以发病后6－9月时,除了存在严重的躯体功能障碍之外,还有严重的心理、社会功能障碍以及角色功能障碍。其中,精神健康和女性患者是工作重点。

Effects of diuretics on intradialytic hypotension in maintenance dialysis patients: a systematic review and meta-analysis

Purpose

Intradialytic hypotension (IDH) is a serious complication in dialysis patients. Diuretics might reduce the incidence of IDH by decreasing ultrafiltration. However, the effect of diuretics on IDH in maintenance dialysis patients is still unclear.

Methods

We searched Medline, Embase, the Cochrane Library, China National Knowledge Infrastructure and clinical trials registries from 1945 to May 2019. Randomized controlled trials (RCTs) or observational studies about IDH in maintenance dialysis with diuretics were included.

Results

Seven studies including 28,226 patients were included, of which 4 were RCTs involving mineralocorticoid receptor antagonists (MRAs) and 3 were observational studies involving loop diuretics. There was a trend that a lower incidence rate of IDH in maintenance dialysis patients who used loop diuretics than control, although the result was not statistically significant (OR 0.65, 95% CI 0.34–1.22, P?=?0.18). Similarly, lower incidence rate of all-cause mortality (OR 0.92, 95% CI 0.87–0.99; P?=?0.02) and cardiovascular (CV) mortality (OR 0.86, 95% CI 0.75–0.99, P?=?0.03) in dialysis patients who used loop diuretics than control. On the contrary, there were no significant difference in the incidence of IDH (OR 1.35, 95% CI 0.78–2.34, P?=?0.29) and all-cause mortality (OR 0.73, 95% CI 0.26–2.01; P?=?0.54) and CV mortality (OR 0.57, 95% CI 0.14–2.25; P?=?0.42) in maintenance dialysis patients who used MRAs compared with control.

Conclusion

Loop diuretics, but not MRAs, might have a potential benefit to reduce the incidence rate of IDH, all-cause mortality and CV mortality. More high-quality studies are needed to strengthen the arguments.

     

卡氏乳香中1个新的降二萜

目的 研究卡氏乳香Boswellia carterii中的化学成分及其抗骨质疏松活性。方法 运用硅胶柱色谱、ODS柱色谱和制备高效液相色谱等方法进行化学成分分离,通过波谱数据及文献对比对其进行结构解析。结果 卡氏乳香的95%乙醇提取物中分离得到11个化合物,分别鉴定为 (1R,2E,8S,9R)-1,9-环氧-8-乙酰氧基-4,5-二氧代降西松烷型-2-烯（1）、rel(1S,3R,7E,11S,12R)-1,12-epoxy-4-methylenecembr-7-ene-3,11-diol（2）、boscartin F（3）、boscartene K（4）、fidmansumbin-13(17)-en-3,16-diene（5）、3α-acetoxyl-7-oxo-tirucalla-8,24-dien-21-oic acid（6）、boscartene N（7）、3β-hydroxy-tirucallic acid（8）、α-boswellic acid（9）、boscarterol O（10）、boscarterol F（11）。结论 化合物1是新化合物,命名为卡氏乳香素,化合物5为首次从乳香中分离得到,化合物2和10首次从该属植物中分离得到。对11个化合物进行抗骨质疏松活性筛选,发现化合物1、3、6和10具有良好的抑制破骨细胞活性。     

Surface modification of titanium implant by microarc oxidation and hydrothermal treatment

Surface modification of titanium implant is processed by microarc oxidation and hydrothermal treatment. A porous surface with a biologically active bone-like apatite layer was formed. The apatite layer consists of very fine crystals and high crystallinity and is integrated with the titanium alloy substrate with a graded structure without a distinct interface. Such a bioactive layer is expected not only to enhance the bony ingrowth into the porous structure, but also to improve the interlocking between implant and bone.
