放疗联合肝动脉化疗栓塞治疗肝癌的研究进展

对于不能手术的原发性肝癌患者，放射治疗配合肝动脉栓塞化疗（TACE）的疗效明显好于单纯放疗或单纯化疗，治疗并发症的发生率和程度可以接受，大多数患者可以耐受。放疗配合动脉栓塞化疗是治疗不能手术的原发性肝癌患者的非常有发展前途的治疗方法。现综述这二种治疗方法的技术特点、疗效和协同作用研究的现状及最新进展。     

Difference in absorption of the two structurally similar flavonoid glycosides, hyperoside and isoquercitrin, in rats.

The present study was to investigate oral absorption of the two similar flavonoid glycosides, isoquercitrin (IQ, quercetin-3-O-glucoside) and hyperoside (HP, quercetin-3-O-galactoside) in rats. Two groups of male SD rats received an oral dose of either IQ (4.5 mg/kg) or HP (6.0 mg/kg). Blood samples were collected via jugular vein at time intervals after drug administration and the plasma concentrations of the studied compounds were analyzed by HPLC. The stability of IQ and HP in the GI tract was also measured by incubation with various GI contents from rats. The results showed that unchanged IQ was barely detectable whereas the glucuronidated quercetin (the aglycone of IQ) was found to be the major form in plasma after oral administration of IQ. In contrast, HP could not be detected in plasma neither as unchanged form nor its aglycone or conjugated aglycone form. Additional in vitro stability studies demonstrated that HP is more stable than IQ in the GI tract. This suggests that IQ could be hydrolyzed easier than HP to its aglycone in GI tract before being absorbed. In conclusion, IQ, as a flavonoid glucoside, could be rapidly absorbed and transformed into glucuronidated quercetin and such absorption might be related to the hydrolysis of the type of sugar moieties attached to its aglycone molecule.     

儿童频繁性眨眼101例的矫治效果

目的:观察分析综合疗法矫治儿童频繁眨眼的疗效。方法:采用心理疗法、药物、手术等去除病因后,均给以针灸等综合疗法,治疗频繁眨眼患儿101例(202眼)。结果:在去除病因后均在心理治疗的诱导下,针刺新明II、攒竹、四白穴,针刺2次频繁眨眼症状消失者68例(67.3%),5次治愈者31例(30.6%),10次治愈者2例(1.4%)。结论:综合疗法是矫治儿童频繁眨眼的有效方法。     

新鲜羊膜移植与自体球结膜移植治疗翼状胬肉的临床观察

目的:观察新鲜羊膜移植与自体球结膜移植治疗翼状胬肉的临床疗效。方法:随机将翼状胬肉患者分为A、B2组。A组30例(32眼)采用翼状胬肉切除联合新鲜羊膜移植。B组37例(40眼)采用翼状胬肉切除及自体球结膜移植。观察术后角膜愈合情况、角膜缘新生血管及角结膜是否有翼状胬肉样组织。结果:术后随访6～18mo,A组复发2眼(6%);B组复发3眼(8%)。结论:自体球结膜移植,取材方便,没有严重的并发症及排斥反应;新鲜羊膜移植损伤小,取材及处理相对复杂,但二者均能有效的减少翼状胬肉的术后复发,复发率相近。

反义DNMT1、DNMT3b基因真核表达载体联合转染对人胆管癌细胞增殖和凋亡的影响

目的观察联合转染反义DNMT1、DNMT3b基因真核表达载体对人胆管癌细胞株QBC-939的增殖能力和细胞凋亡的影响。方法分别构建反义DNMT1基因和反义DNMT3b基因真核表达载体,脂质体介导法将二者先后转染入QBC-939,经G418筛选和荧光细胞克隆挑选得到稳定转染细胞株,并用Western blot检测转染前后的蛋白表达变化;用MTT法和软琼脂克隆形成试验观察各组细胞的增殖能力,流式细胞术检测细胞生长周期及凋亡率的变化。结果Western blot检测证实转染反义基因能使相应蛋白表达水平降低;联合转染反义DNMT1、DNMT3b基因和单独转染反义DNMT1基因能影响QBC-939的生长曲线,使细胞增殖减慢,并以前者为甚;联合转染反义DNMT1、DNMT3b基因和单独转染反义DNMT1基因的细胞克隆形成率分别为(6.78±0.89)%和(14.86±2.13)%,明显低于未转染组;联合转染反义DNMT1、DNMT3b基因和单独转染反义DNMT1能影响QBC-939的细胞周期,使之阻滞于G1期,细胞凋亡率从(1.63±0.27)%分别增加到(18.47±1.46)%和(6.19±0.78)%;在上述效应检测中,单独转染反义DNMT3b基因实验组对QBC-939细胞的生长无明显影响。结论通过联合转染反义DNMT1和DNMT3b基因真核表达载体,能抑制胆管癌细胞的生长和增殖,并促进凋亡的发生,其效果明显优于单独转染DNMT1反义基因;在DNA甲基化的过程中,DNMT1起着主要的作用,DNMT3b扮演着协同的角色,二者通过甲基化途径对胆管癌的发生发挥作用。     

A Survey on the Sexual and Contraceptive Behaviors in Chinese Female College Students

The sexuality of college students, a sexually active population, has been drawing the attention of research-ers[1]. In China, an increasing number of cases of sexu-ally-infected AIDS has been reported[2]. Therefore, it is of great importance to conduct investigation concerning the sexual behaviors of college students. In the past, re-searchers investigated the sexuality in Chinese college students, but no report has been available that especially focused on the sexual behaviors of female col…
