中医药治疗慢性前列腺炎研究概况

综述近年中医药治疗慢性前列腺炎的临床研究,认为本病病因病机之核心在于脾肾亏虚为本,湿热、痰浊、瘀毒为标,病久则伤及脾肾,由实转虚。中医内治法主要以辨证论治、辨病论治或单方验方为主,外治法以中药洗浴、中药灌肠、肛门给药、针灸为主。中医药治疗本病优势明显。应继续完善对中医药作用机制的认识,制订统一的辨证论治及疗效评价标准,针对效果显著的名方开展研究。     

Efficacy and safety of herbal medicines for idiopathic Parkinson's disease: a systematic review.

The objective of this study is to assess the efficacy and safety of herbal medicines (HMs), as a monotherapy or adjunct therapy, compared to placebo or conventional approaches in the treatment of idiopathic Parkinson's disease (PD). We conducted a systematic review of randomized controlled trials from both conventional and alternative medicine sources. Outcome measures were overall improvement, quality of life, reduction of levodopa dose, and adverse events. Nine studies were included, each testing a different HM. Six of the trials had limited internal validity due to major flaws in design, including the lack of proper randomization; insufficient blinding; unclear inclusive criteria in terms of diagnostic criteria, baseline staging, and duration of disease; lack of proper sample size calculation; and insufficient data analysis. Imbalances in gender and ethnicity among the patients in the included trials were observed. No major adverse events emerged, and no specific pattern was detected from the trials describing such data. In addition to major methodological defects, heterogeneity in (1) HM tested, (2) control treatment, and (3) outcome measure hindered in-depth data analysis and synthesis. Current evidence is insufficient to evaluate the efficacy and safety of various HMs. Further studies with improved trial design and reporting, with assessment on cost-effectiveness, quality of life, and qualitative data are warranted.     

类保幼激素对三带喙库蚊幼期发育的影响

本文报告用亚致死剂量的 S—31183(类保幼激素)处理三带喙库蚊幼虫对其发育影响的研究,结果表明处理后蛹期死亡率明显高于幼虫期,并且与剂量大小有关。S—31183处理幼虫并不影响幼虫的发育时间,但可使幼虫化蛹时蜕皮受阻与羽化受到一定的抑制。     

竹林区村庄白纹伊蚊孳生特点的调查

白纹伊蚊在竹林里孳生的阳性比为75.4%;而在竹林包围的居民区阳性比为15.3%。白纹伊蚊在居民区孳生密度布雷图指数为19.4,容器指数为6.2%。居民区孳生蚊虫的主要场所是泡菜坛,泡菜坛主要孳生蚊种是骚扰阿蚊,阳性比为73.7%,其次是淡色库蚊为20.2%,贪食库蚊为14.0%,白纹伊蚊最低,为9.1%。     

猫颈部食管的交感神经支配—HRP法

用5只猫于左侧颈部食管壁内注入 HRP 溶液,通过 HRP 逆行追踪法研究颈部食管的交感神经支配,结果表明:1.长轴突型交感节前神经元直接分布到食管壁内,其标记细胞位于双侧脊髓的胸1～3节段,以胸2节段最多(占标记细胞总数的66.45％),注射侧占优势。标记细胞主要位于中间带外侧核(约占95.02%),其次为侧索、中介核、前角腹后外侧核。其细胞形态不一,以中小型细胞为主(占标记细胞总数的90.4％)。2.支配颈部食管的交感节后神经元主要位于星状神经节(约占61.99％),余者位于双侧颈前、中和2～5胸交感节内、以小细胞最多。     

高血压性脑出血血肿周围脑组织细胞间粘附分子-1的表达

目的探讨急性高血压性脑出血患者细胞间粘附分子-1(ICAM-1)在血肿周围脑组织和正常脑组织中的表达及其意义。方法选择30例行开颅手术治疗的急性高血压性脑出血患者,采用免疫组化技术检测ICAM-1在血肿周围脑组织及正常脑组织中的表达。结果实验组血肿周围脑组织可见ICAM-1的表达水平上调,其表达水平明显高于正常脑组织的表达水平(P<0.01)。神经元和血管内皮细胞共同表达ICAM-1,且神经元表达较明显。结论ICAM-1在人类高血压性脑出血血肿周围脑组织的表达水平上调,其表达上调可能参与了血肿周围脑组织的白细胞浸润,最终引发炎性反应和继发性脑损伤。     

Mammotome微创旋切系统在乳腺外科中的应用(附132例分析)

目的探讨B超引导下Mammotome微创旋切系统对乳腺肿块诊断与治疗的应用价值.方法132例221处乳腺肿块在B超引导下进行Mammotome微创旋切术.其中一侧单发肿块79例,单侧或双侧多发肿块53例,直径0.5～5.2cm,平均1.4 cm,149处肿块临床可扪及.结果所有肿块均完成Mammotome微创旋切切除,平均旋切24次,平均36 min (10～40 min).无一例操作失败.所有肿块均获得明确病理诊断,良性病变129例,乳腺浸润性导管癌3例均行乳腺癌改良根治术.皮肤伤口小,除10例有轻度皮下瘀血外无其它并发症.结论B超引导Mammotome微创旋切系统进行乳腺肿块切除,操作简易,切除彻底,创伤小.     

胎儿声振动刺激反应的研究

目的：了解不同孕龄胎儿对声振动刺激的反应。方法：对４３５例次正常中、晚期妊娠妇女进行声振胎心试验（ＶＡＳ－Ｔ）、声振胎动试验（ＳＰＦＭ），并对声振动刺激前、后胎心率变化规律进行前瞻性研究。结果：（１）从２４周开始，胎儿对声振刺激有反应，但大部分未能达到ＶＡＳ－Ｔ诊断标准，而胎动反应良好。（２）妊娠２８周开始，声振刺激后，９０％以上的胎儿出现显著的胎动、胎心率加速反应，足月胎儿反应率在９８％以上。（３）ＳＰＦＭ阳性率的显著提高早于ＶＡＳ－Ｔ。提示：２８周后胎儿神经系统发育已趋完善。胎儿运动神经的发育成熟早于植物神经。
