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。     

有机氮源对红霉素发酵影响的具体分析

红色糖多孢菌的摇瓶培养基中使用不同有机氮源时红霉素的效价明显不同。通过对不同有机氮源所含营养成分的逐步回归分析,我们得到有机氮源中的苏氨酸为影响红霉素效价的主要因子。最后向对照培养基中添加苏氨酸,则使红霉素的效价比对照培养基提高了22.85%。

Surgical Management of PICA Aneurysm and Incidental Facial Nerve Schwannoma: Case Report.

We report a patient with a posterior inferior cerebellar artery (PICA) aneurysm and an incidental facial nerve schwannoma at the cerebellopontine angle (CPA). A 46-year-old woman presented with the sudden onset of a severe headache, nausea, and vomiting. She had no other abnormal neurological symptoms and signs. Computed tomography (CT) showed hemorrhage in the fourth ventricle. Cerebral angiography demonstrated an aneurysm arising from the tonsillomedullary segment of the left PICA. A facial nerve schwannoma was incidentally found as the aneurysm was being clipped. The aneurysm was clipped via a left transcondylar approach. Subsequently, the schwannoma (2 x 3 x 2 mm) was resected from the facial nerve fascicles, and the facial nerve was preserved. Postoperatively, the patient developed mild to moderate dysfunction of the facial nerve (House-Brackmann grade III [H-B III]) but her hearing was intact. Both a facial nerve schwannoma involving the CPA and an aneurysm involving the PICA can be managed through the transcondylar approach. An asymptomatic facial nerve schwannoma can be resected safely with minimal facial nerve dysfunction.     

耐磷酸盐土霉素菌株选育和发酵的研究

以土霉素生产菌株138^#为出发菌株，经饥饿培养、5-FU、UV、咖啡因复合诱变处理，再用含高磷酸盐的培养基定向筛选，得到高产突变菌株100^#。该突变株遗传特性稳定，代谢特性优于出发菌株，经57m^3发酵罐生产验证，生产稳定，低效价罐批减少59．5％，在磷酸盐浓度提高到0.04％～0.05％时，统计一年的正常罐批平均发酵效价比对照菌株提高5．76％。     

浙江医科大学附二院门诊处方中精神药物使用调查

本文对浙江医科大学附属二院１９９３年７月间３１３７８张合格处方进行统计分析，并用限定日剂量（ＤＤＤ）和药物使用指数（ＤＵＩ）为指标，分析镇静催眠药物使用情况。结果表明苯二氮　类药方２０６７张，占总处方量的６．５９％，巴比妥类药方４９张，占０．１６％，麻醉药方１１１张；占０．３５％。苯二氮　类药方中．女性处方量１２０２张，男性处方量８６５张，男、女组间比较有显著性差异。苯二氮　类药方多分布在神经内科，常用的药有舒乐安定和阿普唑仑。九种常用的苯二氮　类药和麻醉性镇痛药的ＤＵＩ均小于１。提示药物滥用现象少见，该院对这类药物的管理比较严格。麻醉性镇痛药中二氢埃托啡处方占６７．５７％。     

吗啡的呼吸抑制作用与中枢胆碱能系统的关系

本文以兔呼吸频率、通气量和血气作为指标,观察到iv吗啡0.5～4.0mg/kg产生剂量依赖性呼吸抑制。icv匹鲁卡品2.5mg/kg能完全逆转这一抑制效应。icv 4—氨基吡啶(4—AP),1.5μg/kg兴奋呼吸,并使吗啡量效曲线右移。用利血平耗竭儿茶酚胺后,吗啡仍能抑制呼吸,4—AP可消除之。表明吗啡抑制呼吸与中枢胆碱能系统有关,且可能系它抑制Ach释放所致。
