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.

高浓度瘦素自分泌诱导脂肪细胞瘦素抵抗的研究

目的:观察高浓度瘦素对人脂肪细胞分解代谢及脂肪蓄积的直接影响,探讨瘦素自分泌调节在肥胖发生中的作用。方法:取正常成人皮下脂肪组织,常规提取和培养前脂肪细胞,待细胞融合后诱导分化为脂肪细胞后分为二组:低浓度组、高浓度组;分别培养于瘦素终浓度为100ng/ml、1000ng/ml的培养液a中。于培养48h、72h收集培养液检测游离脂肪酸和甘油的浓度,取脂肪细胞行油红O染色并图像分析计算脂肪细胞中脂肪颗粒的积分光密度。结果:与低浓度组相比,瘦素作用48h、72h后,高浓度组培养液中游离脂肪酸浓度均下降[(0.16711±0.011900)mmol/L VS(0.20589±0.008738)mmol/L,(0.17544±0.013920)mmol/L VS(0.23567±0.026220)mmol/L,甘油含量均减少(28.1733±0.91377)μmol/L VS(30.2456±0.30084)μmol/L,(28.9367±0.79530)μmol/L VS(31.8567±0.79024)μmol/L],而脂肪颗粒积分光密度则升高(461136.89±12049.947 VS418570.33±5668.129,441566.56±5921.602 VS 390133.67±7001.304)。结论:高浓度瘦素长时程作用脂肪细胞,可延缓脂肪分解代谢,增加脂肪蓄积。高浓度瘦素经自分泌诱导脂肪细胞产生瘦素抵抗,可能对肥胖发生有重要影响。

罗格列酮对糖尿病大鼠肾脏保护作用机制的探讨

目的 探讨罗格列酮对糖尿病大鼠肾脏的保护作用机制。方法 将大鼠分为正常组、糖尿病组、小剂量罗格列酮组、大剂量罗格列酮组。药物干预4周后，检测各组大鼠的血糖（BS）、三酰甘油（TG）、胆固醇（TC）、肌酐（Scr）水平及尿白蛋白定量（24h）。随后处死大鼠，测定肾组织中丙二醛（MDA）含量、总抗氧化能力（T-AOC）及铜锌超氧化物歧化酶（Cu-ZnSOD）、谷胱甘肽过氧化酶（GSH-Px）、核转录因子-κB（NF-κB）的活性。同时留取。肾脏组织作PAS染色行病理检查。RT-PCR和免疫组化法检测。肾组织中单核细胞化学吸引蛋白质1（MCP-1）mRNA及蛋白质的表达。结果 与糖尿病组相比，大剂量罗格列酮干预组BS、TC、TG差异无统计学意义；而。肾组织MDA含量、MCP-1mRNA及蛋白质表达、NF-κB活性差异有统计学意义（P〈0．05），SOD、GSH-Px、T-AOC活性显著上升；肾小球面积及体积减小。结论大剂量的罗格列酮可显著改善糖尿病大鼠的。肾脏损害，其机制可能与其抗氧化，抑制NF-κB活性，降低MCP-1的含量有关。

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.

输尿管口囊肿的微创手术治疗

目的评价输尿管口囊肿的微创手术治疗方法及其疗效。方法回顾性分析25例行经尿道电切（TURU）手术治疗输尿管口囊肿患者资料。男9例，女16例；年龄18—61岁，平均38岁；单侧18例，双侧7例；单纯输尿管囊肿22例，异位输尿管囊肿3例。结果25例患者手术一次成功22例，手术平均时间15min，术后平均住院3d。术后定期B超、膀胱造影随诊，随诊时间1—9年，3例异位输尿管囊肿合并重复肾、输尿管畸形患者存在术后膀胱输尿管返流，2例再次行开放手术后痊愈。结论TURU是治疗成人输尿管口囊肿的有效方法；当合并存在重复肾输尿管畸形或术后膀胱输尿管返流时，应采用输尿管膀胱抗返流手术。
