解毒化浊和胃方阻断大鼠慢性萎缩性胃炎癌前病变的分子生物学机制

目的:观察解毒化浊和胃方对大鼠慢性萎缩性胃炎(CAG)癌前病变(PLGC)的增殖作用的影响,探讨解毒化浊和胃方阻断大鼠CAG PLGC发展的分子生物学机制。方法:将75只大鼠分为空白对照组、模型对照组、治疗前模型对照组、中药组、西药组,每组15只,除空白对照组外,各组以甲基亚硝基胍造模,造模后模型组给予双蒸水灌胃,中药组给予解毒化浊和胃方灌胃,西药组给予叶酸灌胃。采用免疫组化及原位分子杂交标记的方法测定EGFR蛋白翻译和mRNA转录水平以及病变粘膜组织中增殖细胞核抗原(PCNA)、p21H-ras基因蛋白。结果:对照组PLGC组织EGFR蛋白翻译和mRNA转录水平均有过表达,表达随病变的进展而递增;解毒化浊和胃组EGFR蛋白及mRNA的表达下调,PCNA指数、p21H-ras基因蛋白阳性指数明显低于对照组(P<0．05)。结论:解毒化浊和胃方对大鼠CAG胃癌前病变细胞的增殖有良好的阻断作用,该作用可能与下调PLGC组织EGFR蛋白及mRNA的表达有关。

Food Preparation Knowledge and Confidence of Young Adults

Abstract

Consumer complaints about food products have increased over the past decade due, in part, to consumer error in the preparation of products. Although the food industry assumes that consumers are knowledgeable about food preparation at all stages ranging from purchasing to preparation to storage, little is known about consumers' actual knowledge. The study reported here assessed young adults' food preparation knowledge as well as examined their confidence in their food preparation abilities. Guidelines, based on the findings, are proposed for writing food preparation instructions that have the potential to minimize consumer error and subsequent complaints.

??Objective    To investigate the influence of Bushen Zhuanggu Decoction on the bone healing after teeth extraction in osteoporotic dogs. Methods    Totally 9 female adult dogs whose bilateral ovaries were surgically removed to establish osteoporosis models were randomly divided into 3 groups ??control group??Western medicine group and traditional Chinese medicine group??. Bilateral mandibular premolars were extracted 3 months after castration. Osteoporosis treatment was started the third day after tooth extraction. The dogs in the traditional Chinese medicine group??the Western medicine group and the control group were respectively fed with Bushen Zhuanggu Decoction??Estradiol Valerate Tablets and nothing. The bone mineral density??BMD?? value of dog′s lumbar spine and mandible of each group were detected before and after 3 months of castration and 3 months after teeth extraction. The tissue morphology of the mandible was observed at 1??2 and 3 months after teeth extraction. Results    Three months after teeth extraction??the BMD values of the lumbar spine and mandible in the traditional Chinese medicine group and the Western medicine group were significantly increased compared with those before the osteoporosis treatment??and there was no significant difference compared with the preoperative ones. One month after teeth extraction?? the new bone and the trabecular bone were observed in irregular patterns in the control group and the Westen medicine group??and those were arranged in a mesh pattern in the Chinese medicine group. Two months after teeh extraction??the trabecular bone structure was sparse in the control group??the Western medicine group was more than that of the new bone??and the number of trabecular bone in the Chinese medicine group was more robust. Three months after teeth extraction??the bone trabecular structure was relatively compact in the control group and the gap is small??the new bone tissue and the original bone tissue roughly fused together in the Western medicine group??the new bone tissue of the traditional Chinese medicine group was more similar to the structure of the original bone. Conclusion      Bushen Zhuanggu Decoction can make cancellous bone around the teeth extraction of the osteoporosis canine and significantly increase the amount of bone tissue??so as to promote bone reconstruction and bone healing after teeth extraction.
