华坪县2013-2015年健康人群麻疹抗体水平监测结果分析

目的了解华坪县健康人群麻疹抗体水平,发现工作薄弱地区和免疫空白人群,为实现消除麻疹的目标提供科学依据。方法采用分层抽样方法对华坪县8个乡镇不同年龄段健康人群开展麻疹抗体监测,采用间接酶联免疫吸附试验(ELISA间接法)检测血清麻疹Ig G抗体。结果 2013-2015年共检测1 106人,麻疹抗体总阳性率96.47%。其中,阳性率较低的是2014年(93.13%),人群是8~17月龄组(89.22%)。尚有新庄乡(89.92%)、船房乡(93.98%),通达乡(94.86%)3个乡镇麻疹抗体阳性低于95%。有免疫史者人群阳性率较无免疫史者高(χ~2=5.1830,P=0.023),男女性别间无差异。结论华坪县人群麻疹免疫效果较好,但存在免疫薄弱地区和免疫空白人群,应结合该监测结果,加强重点乡镇麻疹疫苗两剂次接种工作和抗体阴性人群的重新免疫接种。     

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.     

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.

目的观察神经外科手术中雷米芬太尼控制性降压对血液动力学的影响。方法20例ASAⅠ~Ⅱ级择期行颅脑手术患者,采用全凭静脉复合麻醉,术中持续泵注雷米芬太尼行控制性降压,维持MAP 60~70 mmHg,观察降压前(T0)、降压达目标时(T1)、维持降压15 min(T2)、30 min(T3)、停降压15 min(T4)3、0 min(T5)6个时点的MAP、HR、心输出量(CO)、心脏指数(CI)、心室收缩加速度指数(ACI)、左心做功(LCW)、外周血管阻力(SVR)的变化。结果与T0比较,T1、T2、T3时点MAP、SVR、LCW均显著降低(P<0.01);HR亦明显减慢(P<0.05);CO、CI、ACI无明显降低。结论神经外科手术中行雷米芬太尼控制性降压安全、有效,具有对心功能影响小的优点。     

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.
