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.     

肾综合征出血热患者T细胞亚群数量与白细胞介素2,4水平变化的关系

采用ABC免疫组化染色法及单克隆抗体夹心法ELISA，同步检测了34例肾综合征出血热（HFRS）患者外周血T细胞亚群数量和血清白细胞介素2和4（IL－2、IL－4）水平。发现HFRS病程中各T细胞亚群数量均有不同程度的升高，其中CDS阳性T细胞在各病期均有升高。IL－4水平升高仅见于发热期．而IL－2的升高主要在低血压期和少尿期。病程中有CD4／CD8比值的下降甚至倒置。这种比值的变化与IL－2和IL－4的动态变化有一定的相关性。结果揭示，在HFRS发病机理中存在Thl型和Th2型免疫反应等多种免疫病理机制。     

Antigenuria after immunization with Haemophilus influenzae oligosaccharide CRM197 conjugate (HbOC) vaccine

We tested the urine of 30 infants 6 weeks to 7 months of age after they received standard 10-micrograms (0.5-ml) doses of HbOC (HibTITER) Haemophilus influenzae b (Hib) conjugate vaccine for the presence of Hib antigenuria using a commercially available latex particle agglutination assay (Directigen). Urines were collected within 1 hour, from 1 to 3 hours, at 24 hours and at 3, 6 and 9 days after vaccine administration and reactions were quantitated from 0 to 3+. In contrast to previous studies in older children which showed little or no antigenuria following HbOC vaccination, our study shows that in infants intense Hib antigenuria is evident within 2 to 3 hours and persists 3 days after vaccine administration and that less intense antigenuria may be detected in some infants for several days. With efficacious vaccines now being used in 2- to 6-month-old infants, invasive Hib disease may soon be limited to infants of this age just before their seroconversion. It should be recognized that antigenuria occurs for several days after vaccination with Hib conjugate vaccines and that it could be erroneously interpreted as evidence of invasive Hib infection.

“亚地克病”诊断标准探讨及修正建议

在新疆石河子市远郊缺碘地甲病区7～17岁儿童中取样,检测智力、精神运动功能、身高、体重和骨龄,发现精神运动发育障碍和骨龄落后的程度及发生频度明显高于非病区;而智力落后和体格发育落后两区无显著差异。根据这一发现认为在“亚地克病”诊断中,“精神运动发育测验”较“比内测验”更具有特异性和敏感性;建议在“出生、居住于缺碘地甲病区”前提下,将精神运动发育障碍和智力落后并列为主要条件。另根据地克病的分型原则,提出“亚地克病”的分型标准。     

Inhibition by AICA riboside of gluconeogenesis in isolated rat hepatocytes.

5-Amino-4-imidazolecarboxamide (AICA) riboside, the nucleoside corresponding to AICA ribotide (AICAR or ZMP), an intermediate of the de novo pathway of purine biosynthesis, was found to exert a dose-dependent inhibition on gluconeogenesis in isolated rat hepatocytes. Production of glucose from lactate-pyruvate mixtures was half-maximally inhibited by approximately 100 microM and completely suppressed by 500 microM AICA riboside. AICA riboside also inhibited the production of glucose from all other gluconeogenic precursors investigated, i.e., fructose, dihydroxyacetone, and L-proline. Measurements of intermediates of the glycolytic-gluconeogenic pathway showed that AICA riboside provoked elevations of triose phosphates and fructose-1,6-bisphosphate and decreases in fructose-6-phosphate and glucose-6-phosphate. The effects of AICA riboside persisted when the cells were washed 10 min after its addition but were suppressed by 5-iodotubercidin, an inhibitor of adenosine kinase. AICA riboside provoked a dose-dependent buildup of normally undetectable Z nucleotides. After 20 min of incubation with 500 microM AICA riboside, ZMP, ZTP, and ZDP reached 3, 0.3, and 0.1 mumol/g cells, respectively. Concentrations of ATP were not significantly modified by addition of up to 500 microM AICA riboside when the cells were incubated with lactate-pyruvate but decreased with fructose or dihydroxyacetone. The activity of rat liver fructose-1,6-bisphosphatase was inhibited by ZMP with an apparent Ki of 370 microM. It is concluded that AICA riboside exerts a suppressive effect on gluconeogenesis because it provokes an accumulation of ZMP, which inhibits fructose-1,6-bisphosphatase.(ABSTRACT TRUNCATED AT 250 WORDS)     

卵巢未成熟畸胎瘤43例综合治疗疗效分析

为探讨不同手术方式及化疗方法对卵巢未成熟畸胎瘤的疗效及相关影响因素，对43例卵巢未成熟畸胎瘤患者进行回顾性分析。手术方式分为：保守性手术（患侧附件、大网膜切除术＋盆、腹腔腹膜结节切除术＋盆腔淋巴结清扫术）及根治性手术（全子宫、双附件及大网膜切除术＿肿瘤细胞减灭术＋盆腔淋巴结清扫术）。术后采用VAC（长春新碱，阿霉素，环磷酰胺）方案、BEP（博莱霉素或平阳霉素，足叶乙叉甙，顺铂或卡铂）方案或VBP（长春新碱，博莱霉素或平阳霉素，顺铂或卡铂）方案进行联合化疗。患者5年生存率根治性手术为44．4％，保守性手术为64．0％，差异无显著性。VAC方案与BEP（或VBP）方案的5年生存率分别为33．3％和77．3％（P＜0．01）。疗程数≥4患者的5年生存率为73．9％，明显高于疗程数＜4患者的38．9％（P＜0．05）。认为对于有生育要求的卵巢未成熟畸胎瘤患者，可仅行保守性手术，术后辅以联合化疗。BEP（或VBP）方案对患者长期生存率的改善明显优于VAC方案。术后化疗的疗程数与疗效有关，对长期生存率的影响较明显。
