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.

慢性萎缩性胃炎是以胃黏膜上皮和腺体萎缩、黏膜变薄为特征的慢性疾病。属中医胃脘痛、胃痞等范畴。其病因病机较为复杂,多与饮食不调、情志不畅有关,尤其是饮酒、过食刺激之品,致使脾胃受损,阳气郁遏不振,纳运失司,化源不足,气血阴液亏乏;或中焦运化无力,湿邪滞塞,郁而化热;或     

Reproducibility of ultrasound pachymetry using the Sonogage Corneo-Gage Plus 2.

PURPOSE: The aim of this study was to determine the reproducibility of measurements made using the Sonogage Corneo-Gage Plus 2 (Cleveland, Ohio) ultrasound pachymeter of total corneal and corneal epithelial thickness in 5 different regions of the cornea. METHODS: Twenty-seven subjects at the New England College of Optometry (NECO) and 20 subjects at the Southern College of Optometry (SCO) were enrolled in this study. Measurements were taken of the central cornea as well as the nasal and temporal regions of the midperipheral and peripheral regions of the right cornea of each subject. Identical measurements were again taken in these subjects 1 week later at approximately the same time of day. Within-subject variations were then assessed using paired t tests. RESULTS: The only significant measurement differences that were found between visits were for full corneal thickness at both the nasal and temporal midperipheral locations. The mean differences for these locations were 13.5 microm and 13.7 microm, respectively. CONCLUSIONS: Epithelial corneal thickness and central and peripheral total corneal thickness measurements using the Corneo-Gage Plus 2 pachymeter were reproducible; however, midperipheral total corneal thickness measurements showed poor reproducibility.     

表皮生长因子对牛眼小梁细胞c—fos基因表达的诱导

目的研究表皮生长因子（ｅｐｉｄｅｒｍａｌｇｒｏｗｔｈｆａｃｔｏｒ，ＥＧＦ）对小梁细胞的作用。方法应用分子杂交技术研究ＥＧＦ对体外培养的牛眼小梁细胞ｃ－ｆｏｓ基因表达的诱导和３Ｈ胸腺核苷酸（３Ｈ－ｔｈｙｍｉｄｉｎｅｉｎｃｏｒｐａｒａｔｉｏｎ，３Ｈ－ＴｄＲ）掺入法观察细胞ＤＮＡ的合成。结果小梁细胞的３Ｈ－ＴｄＲ掺入率随着ＥＧＦ浓度不同而变化，浓度为２０～１５０ｎｇ／ｍｌ时，细胞掺入率随浓度增加升高（Ｐ＜０．０１）。与对照组相比，ＥＧＦ刺激停止生长的小梁细胞０．５小时后，ｃ－ｆｏｓ基因开始表达，１小时后达高峰，至２小时后消失。不同浓度ＥＧＦ刺激小梁细胞１小时后，ｃ－ｆｏｓ基因表达呈浓度依赖性。结论实验结果表明ＥＧＦ刺激小梁细胞增殖或进入生长状态，可能与ｃ－ｆｏｓ基因产物的信号传递作用有关。

Time trends and occupational risk factors for pleural mesothelioma in Sweden.

Epidemiologic data on pleural mesothelioma are scarce on regional and occupational time trends, which would monitor the effects of changes in exposure to asbestos. We aim to characterize time trends, regional, socioeconomic, and occupational risk factors for pleural mesothelioma in Sweden in the years from 1961 to 1998. The Swedish Family-Cancer Database was used to identify patients with pleural mesothelioma. Age-standardized incidence rates and standardized incidence ratio (SIR) were calculated for the population in the Database. A total of 1298 male and 233 female pleural mesotheliomas were retrieved. Age-standardized incidence of the disease was highest, and the trend increased in residents of large industrial and shipbuilding cities. In the last follow-up period, the male rate exceeded the female rate about 10-fold. Among male socioeconomic groups, manual workers showed the highest and ever-increasing SIR. No female socioeconomic group was at risk. For men, plumbers and seamen had the highest risk of 4.56 and 2.83, respectively, but the risks appeared to be decreasing for plumbers, whereas no clear trend was noted for seamen, probably because of indirect expose in ships. Farmers showed an SIR of 0.28, indicating that the population at large was at four times higher risk than farmers. The SIRs of many academic/college-educated groups were two to six times higher than those of farmers, suggesting indirect exposure to asbestos in these groups.
