Association of Helicobacter pylori Infection with Gastric Adenocarcinoma

Gastric adenocarcinoma is the most prevalent cancer in South Korea, and Helicobacter pylori (H. pylori) infection is also common. This study was performed to examine the association between H. pylori infection and gastric cancer, taking into account various other factors. To investigate the association between gastric adenocarcinoma and H. pylori infection, determined by urease-positive reaction in the CLO test, a total of 175 paired specimens (175 tumor and 175 tissues adjacent to tumor) of stomach cancer patients and a total of 113 control specimens were obtained. The positive H. pylori infection rates were 78.9% (138/175) among the patients in specimens of tumor or tissues adjacent to the tumor and 41.6% (47/113) among controls in the CLO test. A positive correlation between H. pylori infection and gastric cancer was observed (age-adjusted odds ratio, 7.0; MH χ²=34.5 with P <0.0005). These data suggest that stomach cancer patients in Korea have high infection rates of H. pylori regardless of site specificity, and this infection might be causally associated with stomach cancer.     

半夏厚朴汤对小鼠胃排空及小肠推进功能的影响

目的:为了研究半夏厚朴汤及其各组成药物对小鼠胃排空和小肠推进功能的影响,以及五味组成药物在该方剂中的作用大小和它们之间的交互作用。方法:以大分子色素葡聚糖蓝2000为标记物,用正交设计的方法安排实验,观察给药一段时间后小鼠的胃内色素残留量和该色素的小肠推进比。结果:正交设计结果表明,半夏厚朴汤中五味药物对小鼠小肠推进功能的促进作用依次从大到小排列的顺序为:半夏、茯苓、苏叶、厚朴、生姜;对胃排空的促进作用依次从大到小排列的顺序为:厚朴、苏叶、半夏、生姜、茯苓。五味药物之间存在着较广泛的一级交互作用。结论:半夏厚朴汤及其组成药物均有促进在体小鼠胃排空和小肠推进功能的作用。     

艾灸涌泉穴对老年大鼠自由基代谢影响的研究

目的:探讨艾灸延缓衰老的作用机理。方法:建立自然衰老大鼠模型,分为老年时照组、维生素 E 组及艾灸组,观察大鼠血清和脑组织超氧化物歧化酶(SOD)活性、过氧化脂质(LPO)含量。结果:老年大鼠组血清和脑组织 SOD 活性明显低于青年大鼠组,LPO 含量明显高于青年大鼠组。艾灸组灸涌泉穴后,与老年对照组比较,其血清和脑组织 SOD 活性明显升高(45.30±6.17、35.03±3.67u/ml,P<0.01;2399±316、2005±206u/g 脑组织湿重,P<0.01); LPO 含量明显降低(3.30±0.55、4.40±0.51μmol/L,P<0.01;341±69、446±44nmol/g 脑组织湿重,P<0.01)。维生素 E 组大鼠与老年对照组大鼠比较,其血清和脑组织 SOD 活性差异无显著性。结论:艾灸涌泉穴能增强 SOD 活性,提高老年大鼠清除自由基的能力,改善老年大鼠自由基代谢失调的状况,从而阻止自由基损害机体,保护脑功能,延缓脑衰老,推迟衰老进程。

Compatible leaching effect of Concha Ostreae and some commonly-used Chinese medicinal materials]

OBJECTIVE: Based on a study of Concha Ostreae, to provide some reference for the rational approach to leaching mineral drugs. METHOD: Taking the change rates of compatible leaching and value of A as targets, the compatible leaching effect of Concha Ostreae with Radix et Rhizoma Rhei Praeparata, Radix Scutellariae, Pollen Typhae and Fructus Aurantii lmmaturus was studied. RESULT: If Concha Ostreae and the above cited medicinal herbs are decocted together, the yield of extract may be reduced to a certain extent, but the target composition of Radix et Rhizoma Rhei Praeparata and Fructus Aurantii lmmaturus remains intact, only the content of Radix Scutellariae baicalin may be influenced. CONCLUSION: The relationship of technology with preparation must be taken into consideration when making choice of the proper way to leach Concha Ostreae.     

重组人催乳素(rhPRL)在huPBL/SCID嵌合模型中对人直肠癌的治疗效应及免疫机理初探

通过体内实验进一步证实rhPRL对机体免疫功能的调节作用,以及用于过继细胞免疫治疗的可能性。我们选用CB17 SCID纯系小鼠,腹腔注入人结肠腺癌细胞(HT29),2小时后腹腔注入尼龙毛纯化的人淋巴细胞(T/NK细胞),同时开始进行rhPRL治疗,并设HBSS对照和rhIL-2治疗对照组。结果表明,rhPRL在体内外均无直接抗癌效应,反而可促进肿瘤生长。当SCID荷瘤鼠同时移植入人的T/NK细胞时出rhPRL可明显提高T/NK细胞的抗癌效果,生存期明显延长(P<0.05)。平均生存期由70.4天延至112.1天,在对照组全部死亡时(d105),rhPRL治疗组有60％存活,且在实验终止时(>160天)仍有40％存活。分析其抗癌机理发现,rhPRL体外可直接促进人T/NK细胞增殖,其分泌上清可抑制肿瘤生长,同时发现人T/NK细胞与HT29共育4小时中rhPRL亦可直接促进杀伤活性。
