Modified superficial parotidectomy: preserving both the great auricular nerve and the parotid gland fascia.

OBJECTIVE: To reduce the incidence of sensory deficits and Frey's syndrome by modifying the traditional superficial parotidectomy. STUDY DESIGN: After raising the skin flap, the parotid gland fascia (PGF) was elevated to form a posterior pedicle fascial flap and then was replaced after the gland removal. The great auricular nerve (GAN) that runs within the PGF was not separated, so both the GAN and the PGF were preserved. Before this modification, the GAN and PGF were examined anatomically. The complication rates in the modified and control groups were compared. RESULTS: 1) The GAN, which runs within the thick and pycnotic PGF, trifurcates into postauricular, preauricular and lobule branches. The modification could be carried out practically based on the anatomy study. 2) Long-term sensory deficit was encountered in 13.3% of the control group, but 0% in the modified one. Frey's syndrome was suffered by 66.7% and 16.7% cases in the control and modified group respectively. The incidence of other complications was not significantly different. CONCLUSION: Our modification is practical. It decreases the complications significantly. EBM rating: B-3b.

暗纹节菱孢所致皮肤真菌病组织病理学及超微结构观察

本文报告了暗纹节菱孢[Arthinium phaeospemum（Corda）Ellis]所致皮肤真菌病的组织病理学及超微结构观察。HE、PAS、镀银染色（Szatri）法及铅铀染色，对皮损的组织病理改变，进行了光镜及透射电镜观察。光镜下发现暗纹节菱孢引起真皮及皮下脂肪组织广泛性病理浸润，由多种细胞构成的肉芽肿，尤其对皮肤附属器严重破坏。在病理浸润中可见球形、卵圆形、菱形及晶体形，玫瑰红色、棕色及褐色孢子。透射电镜下见真皮成纤维细胞胞浆内吞噬多数界线清楚的圆形小体，空泡内也有相同的小体，胞浆空泡甚多，胞核完整。同时见到破坏的溶酶体。病理浸润内形态各异的孢子及不同颜色，是孢子生长的不同阶段。     

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.     

广龙昊膏药对大鼠腰椎间盘突出模型细胞因子IL-1、NO及组织胺的影响

为探讨IL-1、NO及组织胺在腰椎间盘突出中的作用及广龙昊膏药的治疗效果，将60只大鼠造模并随机分为正常组（A组）、造模组（B组）、广龙昊膏药组（C组）和奇正止痛膏组（D组），观察其神经根周围局部组织中IL-1、NO及组织胺的含量。结果显示，B组中的IL-1、NO及组织胺较A组显著升高（P〈0．01）。C组、D组较B组明显下降（P〈0．01）。表明大鼠腰椎间盘突出模型中细胞因子IL-1、NO及组织胺明显增加可能是腰椎间盘突出中的潜在始动或促进因素，而C组能显著降低神经根局部中IL-1、NO及组织胺的含量，说明广龙昊膏药作用部分是通过抑制炎性细胞因子的活性实现的。

电针对狗血浆与胃黏膜组织中NO和NOS的影响及其意义

目的　观察电针对狗幽门压力、胃黏膜血流量的调控作用及其与血浆、胃黏膜组织中一氧化氮 (NO) ,一氧化氮合酶 (NOS)水平变化的关系 ,以探讨电针对胃黏膜保护作用的机制。方法　将 2 0只狗随机分为 4组 :空白对照组、非经非穴组、上巨虚组、足三里组 (每组 5只 )。采用胃压测量仪、激光多普勒血流仪监测幽门压力、频率及胃黏膜血流量的变化 ,同步测定血浆及胃黏膜组织中NO ,NOS含量 ,并观察变化规律。结果　电针后足三里组幽门括约肌总压力、基础压下降、频率下降 (P <0 .0 5 ) ,胃黏膜血流量显著升高 (4 .5 1± 0 .73→ 6.90± 1.0 1,P <0 .0 1) ,血浆及胃黏膜组织中NO ,NOS含量显著升高 (P <0 .0 5 ) ,上巨虚组仅幽门括约肌总压力下降 ,血浆NO含量上升。但足三里组各项监测指标变化趋势更明显 ,其他组变化无显著性。结论　电针可使狗幽门压力、频率下降 ,使胃黏膜血流量增加 ,与影响幽门压力、胃黏膜血流量的某些活性物质的含量改变有关 ,并具有一定的经络和穴位特异性。
