Promoting effect of the Chinese medicinal herb, wikstroemia chamaedaphne and tung oil extracts on carcinoma of the uterine cervix induced by HSV-2 or methylcholanthrene (MCA) in mice

The promoting effect of the Chinese medicinal herb, Wikstroemia chamaedaphne and Tung oil extracts (WC and HHPA) on carcinoma of uterine cervix induced by HSV-2 or MCA in mice was studied. The results showed that WC and HHPA extracts were not carcinogenic themselves. After carcinogen HSV-2 and MCA treatment, WC and HHPA were added separately. The inducing rates by HSV-2 increased from 7.4% to 21.1% and 26.3%, those by MCA increased from 56.5% to 82.8% and 84.4%. There was a significant difference between the combined groups and groups with HSV-2 or MCA only. The experimental results suggest that these two kinds of extracts play a promoting effect on carcinogenesis. The relation between the carcinogenesis of uterine cervix or nasopharynx and WC or HHPA extracts is discussed.     

提上睑肌三阶梯手术矫正上睑下垂的临床应用

目的 探讨提上睑肌三阶梯手术矫正上睑下垂的适应范围及效果。方法 根据提上睑肌肌力和上睑下垂的程度，将患者分为三组。A组为提上睑肌肌力好，上睑呈轻度下垂者。单纯采用提上睑肌徙前术矫正。B组为提上睑肌有一定的肌力，上睑呈中度下垂者。在提上睑肌徙前术的基础上。行提上睑肌缩短术矫正。C组为提上睑肌肌力差，上睑呈重度下垂者。在提上睑肌徙前、缩短术的基础上行提上睑肌反折悬吊术矫正。结果 87例患者术后随访6～30个月，上睑缘位于角膜缘下1mm．眼睑弧度自然，两眼对称，眼睑闭合自如，无暴露性角膜炎及结膜脱垂等并发症，效果满意。结论 提上睑肌徙前、缩短、反折悬吊三阶梯手术，可广泛适用于矫正不同程度的上睑下垂。     

微小切口胆囊切除术2260例效果观察

目的 总结微小切口胆囊切除术治疗胆道系统疾病的经验。方法 对2002-2004年连续收治的2260例胆囊、胆道系统疾病实施微小切口手术的临床观察资料进行回顾性分析。结果 本组2260例微小切口胆囊切除术的患者无一例因手术原因死亡；术后无残留小胆囊；无胆汁漏及腹腔脓肿，亦无伤口全层裂开及切口疝形成。结论 该术式损伤小、局部显露清楚、不易发生副损伤，可同时行胆总管探查术，特殊情况下可随时改变手术方式。     

Association of the GNAS1 gene variant with hypertension is dependent on alcohol consumption.

The beta-adrenoceptor (beta-AR)-stimulatory guanine nucleotide-binding (Gs) protein system has been shown to play important roles in the cardiovascular system. The gene encoding the alpha-subunit of Gs proteins (GNAS1) is a candidate genetic determinant for hypertension. Because alcohol consumption is known to affect blood pressure partly through the beta-AR-Gs protein system, we examined the possible interaction between GNAS1 T393C polymorphism and drinking status in the association with hypertension in the present study. As a result, a non-significant but reasonable trend supporting the presence of an interaction was shown (p = 0.076). In line with this trend, the T393C polymorphism significantly interacted with drinking status in the association with systolic blood pressure (p = 0.028). Moreover, supporting the presence of an interaction, T allele carriers consistently had a higher probability of hypertension, higher systolic blood pressure, and higher diastolic blood pressure than CC homozygotes in non-drinkers and light drinkers. In contrast, CC homozygotes consistently had a higher probability of hypertension, higher systolic blood pressure, and higher diastolic blood pressure than T allele carriers in moderate to heavy drinkers. The present study also showed a significant interaction between the T393C polymorphism and drinking status in the association with pulse pressure (p = 0.026), reflected by a significant association between the T393C polymorphism and pulse pressure in moderate to heavy drinkers (p = 0.026). These findings may be helpful in conducting further molecular and biological studies on the relationship among the effects of alcohol, the beta-AR-Gs protein system, and hypertension.

酪氨酸激酶抑制剂对气管上皮细胞生长的影响

目的探讨酪氨酸激酶抑制剂(Tyrosine kinase inhibitor,TKI)对培养气管上皮细胞生长的影响.方法通过MMT法、3H-胸腺嘧啶(3H-TdR)掺入法及流式细胞计数,观察3种TKIs:Tyrphostin AG1478、Genistein(Sigma)及金转停对原代培养的大鼠气管上皮细胞增殖、周期及凋亡的影响,以及TKIs对表皮生长因子(EGF)的阻断作用.结果MTT法显示3种TKI均对气管上皮细胞的生长具有时间和剂量依赖性抑制作用,同时,TKI阻断EGF对气管上皮细胞生长的刺激作用,3种TKIs的作用无明显差异;1μmol/L的Tyrphostin AG1478、Genistein及金转停分别使气管上皮细胞的TdR掺入率降低18.3%、20.9%及19.7%,与MTT比色法结果一致.同时,Tyrphostin AG1478不仅加速气管上皮细胞的凋亡而且阻止细胞有丝分裂.TKIs可阻断表皮生长因子(EGF)对气管上皮细胞生长的刺激作用.结论TKIs不仅抑制对原代培养的大鼠气管上皮细胞的生长,加速其凋亡,而且可阻断EGF对气管上皮细胞生长的刺激作用,3种抑制剂的作用无明显差异.
