Trace element levels in drinking water and cognitive function among elderly Chinese

The relation between trace element levels in drinking water and cognitive function was investigated in a population-based study of elderly residents (n = 1,016) in rural China in 1996-1997. Cognitive function was measured using a Chinese translation of the Community Screening Interview for Dementia. A mixed effects model was used to evaluate the effect of each of the elements on cognitive function while adjusting for age, sex, and educational level. Several of the elements examined had a significant effect on cognitive function when they were assessed in a univariate context. However, after adjustment for other elements, many of these results were not significant. There was a significant quadratic effect for calcium and a significant zinc-cadmium interaction. Cognitive function increased with calcium level up to a certain point and then decreased as calcium continued to increase. Zinc showed a positive relation with cognitive function at low cadmium levels but a negative relation at high levels.     

黄连种子胚后熟期间的生理生化变化及激素的影响

黄连种子需要在低温条件下才能解除休眠。本文对黄连种子层积在室外和冰箱两种条件下,种胚后熟过程中的淀粉酶活性及DNA、蛋白质的变化规律作了测定,并对ABA处理后种子的生理生化变化作了研究。     

不同灸治时程对阳虚小鼠免疫功能影响的比较

本采用不同灸治时程（５分钟，１５分钟，２５分钟）治疗阳虚小鼠模型，结果显示：不同灸治时程对阳虚小鼠模型的Ｔ淋巴细胞酯酶阳性率，白细胞介素Ⅱ的影响存在的差异，灸１５分钟可显提高阳虚小鼠Ｔ淋巴细胞酯酶阳性率（Ｐ〈０．０１），灸５分钟，２５分钟则无显作用，灸１５分钟和２５分钟均可显提高阳虚小鼠白细胞介素Ⅱ的活性，二之间无显性差异，灸５分钟无此显作用，提示在改善阳虚小鼠免疫功能有作用上，以灸     

绞股蓝总甙复合国产1号避孕片对健康妇女脂类代谢及血压的影响

本研究将180名已婚、一孩、年龄33±5岁,需要使用避孕措施的健康妇女随机分成6组,即IUD组、绞股蓝总甙加IUD组、1号OC片组、40mg、60mg、80mg绞股蓝总甙分别与1号OC片复合的3个试验组.用双盲法给药,连续服用6个月观察脂类代谢和血压的变化.结果显示:以IUD组和1号OC片组的数据为参比值.服用不同剂量绞股蓝总甙复合口服避孕药后无升高TG和TC的趋势,有显著升高HDL-C作用和使APOA_1水平上升的趋势;亦存在降低收缩压的趋势,对舒张压无明显影响,但在服药后3个月时HDL-C水平曾发生暂时性下降.

三氧化二砷对神经母细胞瘤细胞增殖的影响

目的探讨三氧化二砷（Ａｓ２Ｏ３）对儿童神经母细胞瘤有无潜在的治疗价值及伍用细胞因子有无增强疗效的作用。方法应用四甲基偶氮唑蓝法于体外观察Ａｓ２Ｏ３对神经母细胞瘤细胞株ＳＪ－Ｎ－ＳＨ增殖的影响；并观察Ａｓ２Ｏ３伍用重组人γ－干扰素、肿瘤坏死因子、白细胞介素４、６、１０后的情况。结果０．５～４μｍｏｌ／Ｌ的三氧化二砷明显抑制ＳＪ－Ｎ－ＳＨ细胞的增殖，Ａｓ２Ｏ３伍用γ－干扰素、白细胞介素４可明显增强Ａｓ２Ｏ３对ＳＪ－Ｎ－ＳＨ细胞增殖的抑制，而其他几种细胞因子无明显作用。结论Ａｓ２Ｏ３为治疗神经母细胞瘤的有效药物，联合应用合适的细胞因子可增强Ａｓ２Ｏ３的疗效。     

Genotypic analysis of tumor suppressor genes PTEN/MMAC1 and p53 in head and neck squamous cell carcinomas

Objectives: Tumor suppressor gene mutations in both p53 and PTEN/MMAC1 genomic DNA have been detected in many types of cancer. The purpose of this study was to investigate the presence and importance of PTEN/MMAC1 mutations in squamous cell carcinomas. Methods: Exons of each gene were amplified after polymerase chain reaction (PCR) using genomic DNA derived from cell lines of squamous cell carcinoma of the head and neck (SCCHN) and snap-frozen biopsy specimens from primary established head and neck tumors. The amplified and purified DNA was then sequenced directly. Result: As anticipated, point mutations of the p53 gene were found in 80% of cell lines examined. A single base mutation in codon 151 was found in six of 10 cell lines studied. PTEN/MMAC1 gene mutations were found in neither the cell lines tested nor the tumor biopsy samples. Conclusion: This study, as well as a large volume of data, confirms that mutations of the p53 gene are frequent events in head and neck cancer cell lines. Although PTEN/MMAC1 gene mutations have been found in a variety of carcinomas, this gene was not found to be mutated in SCCHN cell lines or in primary squamous cell carcinomas of the head and neck. This information is useful for further studies of mutations in these cell lines. Laryngoscope, 108:1553–1556, 1998     

试论方剂功效表达的历史沿革及现代研究意义

方剂的历史悠久，但真正将方剂作为研究对象，出现方剂功效的描述则始自金代成无己，并在明清时期有了较大的发展，而直到建国后才形成一定的规范。目前古方中还存在大量的方荆只有简单的组成与主治，而没有详细的方论，包括方剂功效。文章最后论述了方荆功效理论研究的重要性与可行性。
