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.     

Immunological responses to pneumococcal vaccine in frail older people

Advanced age has been associated with a wide range of defects in both the innate and adaptive immune systems including diminished specific antibody responses that increase the risk of invasive pneumococcal disease (IPD) and limit the effectiveness of vaccines. However, the elderly are a heterogeneous group and measures of overall frailty may be a better indicator of disease susceptibility (or vaccine response) than chronological age alone.

Stromal progenitor cell therapy corrects the wound-healing defect in the ischemic rabbit ear model of chronic wound repair

Chronic wounds create a formidable clinical problem resulting in considerable morbidity and healthcare expenditure. The etiology for wound healing impairment appears to be multifactorial; however, ischemia is a common factor in most types of chronic wounds. Ideal therapy for such wounds would be to correct deficiencies in growth factors and matrix components and provide cellular precursors required for timely wound closure. We hypothesized that stromal progenitor cell (SPC) therapy could correct the ischemic wound-healing defect through both direct and indirect mechanisms. To test this hypothesis, we used the ischemic rabbit ear model of chronic wound healing. We found that treatment of the wounds with SPCs was able to reverse the ischemic wound-healing impairment, with improved granulation tissue formation and reepithelialization compared with vehicle or bone marrow mononuclear cell controls. In vitro, SPCs were found to produce factors involved in angiogenesis and reepithelialization, and extracellular matrix components, providing evidence for both direct and indirect mechanisms for the observed correction of the healing impairment in these wounds. Treatment of ischemic wounds with SPCs can dramatically improve wound healing and provides a rationale for further studies focused on SPCs as a potential cellular therapy in impaired wound healing.     

石英纤维增强型复合树脂桩核修复牙体缺损的护理配合

对9例脑性盐耗综合征患者进行静脉补钠和口服盐胶囊治疗，结果患者血清电解质紊乱及时纠正。提出严密观察神经系统及低血容量症状，及时监测水、电解质平衡状况；静脉补钠时，注意补液量及速度；口服盐胶囊时，做好健康教育，防止并发症发生，同时动态调整静脉补钠量和口服盐胶囊量是获得满意疗效的关键。     

Extragastrointestinal stromal tumor possibly originating from the prostate

We report a case of extragastrointestinal stromal tumor possibly originating from the prostate. The patient underwent radical prostatectomy because of no metastatic evidence. No recurrence and metastasis have been found during 14 months of follow up. To our knowledge, this may be the third such case published in a report in terms of pathological type.     

间接免疫荧光法检测婴幼儿急性下呼吸道合胞病毒感染的特异性IgM

本文对1984年1～3月和1985年3～8月共107例急性下呼吸道感染的住院患儿,采用间接免疫荧光法检测其急性期血清抗RSV特异性IgM抗体,并与病毒分离和/或中和试验比较,敏感性为82.1％,特异性为71.8％。RSV感染患儿发病后3天内大多数病例即可从血清中检测出RSV-IgM,因此该法具有早期诊断价值。     

蓖麻油引产餐对妊娠大鼠分娩的影响

目的蓖麻油引产餐用于妊娠晚期引产效果明显，但其作用机制不清楚。本研究通过引产餐灌服妊娠大鼠建立动物引产模型，以期了解引产餐对妊娠大鼠分娩启动和产程的影响，并初步探讨蓖麻油引产餐活性成份。方法于大鼠妊娠第１８～２０天灌服引产餐，观察大鼠分娩启动和分娩产程变化。利用高压液相分析蓖麻油和蓖麻油引产餐中脂肪酸成份。结果引产餐可提前妊娠大鼠分娩启动时间，缩短分娩产程。蓖麻油引产餐和蓖麻油两者脂肪酸对比结果显示，成份相同，蓖麻酸均占９０％，未见花生四烯酸成份。结论引产餐对妊娠晚期大鼠具有引产、催产作用，可以利用引产餐灌服妊娠大鼠建立动物引产模型。推测蓖麻酸是引产餐启动分娩和缩短产程的活性物质。
