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。     

基于BGP、TGF-β1的表达探究蛇床子素对去卵巢致骨质疏松大鼠的作用

目的观察蛇床子素对去卵巢致骨质疏松大鼠的影响。方法选取3月龄雌性SD大鼠30只,随机分为蛇床子素组(A组)、模型对照组(B组)、假手术组(C组),各10只。A、B 2组摘除卵巢构建去势大鼠骨质疏松模型,C组仅进行手术、不摘除卵巢。造模成功后,分别给予相应药物灌胃,连续给药12周,处死。然后测量骨密度,检测治疗后血清BGP、TGF-β1、钙指标。结果B组大鼠股骨骨密度较C组明显降低(P<0.05);经12周治疗,A组股骨骨密度较B组明显升高(P<0.05)。与C组比较,B组大鼠血清中BGP含量升高、TGF-β1降低(P<0.05);与B组比较,A组大鼠血清中BGP降低、TGF-β1含量升高(P<0.05)。与C组比较,B组大鼠血清Ca水平明显降低(P<0.05);与B组比较,A组大鼠血清Ca水平明显升高(P<0.05)。差异均有统计学意义。结论蛇床子素能够有效通过调节大鼠体内激素分泌改善去卵巢大鼠的骨代谢异常,提高骨密度,对骨质疏松症起到一定的防治作用。     

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.     

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。

Study of drug control over postoperative hemorrhage after selective caesarean section

Objective: To compare the efficacy and safety of carbetocin and oxytocin in the prevention of postpartum hemorrhage after selective caesarean section. Methods: Two hundred and sixteen pregnant women who were going to deliver by caesarean section were randomly divided into two paralleled and controlled groups, of which the oxytocin group(group A) contained 105 women and the carbetocin group(group B) 111 women. 20 IU of oxytocin was administrated during operation for both groups, 10 IU directly into uterus and 10 IU intravenously. When the operation was over, 20 IU of oxytocin was dripped for group A lasting for 8 hours, while for group B 100μg of carbetocin was immediately injected intravenously for 1 minute. Blood loss as well as hemoglobin alteration was measured for the comparison of the effect of the two drugs. Blood biochemical indicators were introduced for the evaluation of the safety of carbetocin including the function of liver and kidney and the fasting glucose.Results: No significant difference was revealed between the two groups concerning the postpartum hemorrhage within 24 hours, the postpartum hemorrhage incidence and the changes of hemoglobin. There was no significant difference in the change of liver and kidney function, fasting glucose and electrolyte changes as well.Conclusions: Carbetocin has a similar effect and safety of oxytocin in controlling the blood loss of selective caesarean section.
