131Ⅰ治疗老年与非老年分化型甲状腺癌肺转移

目的探讨老年分化型甲状腺癌(DTC)肺转移的131Ⅰ治疗效果及主要影响因素与非老年人的差异。方法回顾性分析2005年1月—2011年12月期间在南通大学附属肿瘤医院核医学科进行131Ⅰ治疗的38例DTC肺转移患者,将其分为老年组17例和非老年组21例,采用胸部CT、131Ⅰ显像及Tg变化综合判断131I治疗效果差异,并对可能影响131Ⅰ治疗DTC肺转移效果的主要因素进行分析。结果老年组与非老年组比较:131Ⅰ治疗有效率老年组为9例(52.9%),非老年组为18例(85.7%,P=0.0364,P<0.05),2组差异有统计学意义。主要影响因素分析:合并其他脏器远处转移(P=0.0126)及肺病灶类型(P=0.0211),均P<0.05,2组差异有统计学意义;而性别(P=0.8634)、肿瘤病理分类(P=0.6475)及颈部淋巴结转移(P=0.9177),均P>0.05,2组差异无统计学意义。结论老年DTC肺转移的131Ⅰ治疗效果不及非老年,其主要影响因素与非老年略有差异,但其仍不失为一种有效、安全的治疗方法。     

CGB5对卵巢癌细胞OVCAR-3成瘤率及成瘤速度影响的体内研究

目的 :通过体内实验研究β绒毛膜促性腺激素的第5号亚基(chorionic gonadotropin beta polpeptide 5,CGB5)对卵巢癌细胞OVCAR-3成瘤率及成瘤速度的影响。方法:采用慢病毒载体转染的方法 ,在卵巢癌细胞OVCAR-3中分别转入CGB5小干扰、过表达及无关序列。另外,未处理的OVCAR-3细胞作为空白对照,将高表达CGB5的绒癌细胞Be Wo作为阳性对照。用RT-PCR和酶联免疫吸附试验法测定转染后细胞的CGB5浓度。裸鼠随机分为5组(正常OVCAR-3细胞组,CGB5小干扰组,CGB5过表达组,CGB5无关序列组,Be Wo细胞组),每组6只,将这5种不同的细胞株分别打入裸鼠右侧腋窝皮下建立皮下移植瘤模型。观察5组模型的肿瘤成瘤率及成瘤速度,并用免疫组化测定肿瘤细胞增殖指标Ki67的表达情况。结果:(1)CGB5过表达组和Be Wo细胞组裸鼠的皮下移植瘤成瘤率是100%(6/6),OVCAR-3正常细胞组和无关序列对照组细胞的裸鼠的皮下移植瘤成瘤率是83.3%(5/6),而CGB5小干扰组细胞的裸鼠皮下移植瘤成瘤率是33.3%(2/6)。(2)CGB5过表达组和CGB5表达高的Be Wo细胞组的肿瘤生长较快,而CGB5小干扰组的肿瘤生长最慢。结论:CGB5能增加卵巢癌OVCAR-3细胞皮下移植瘤的成瘤率及肿瘤的生长速度,这将有望为卵巢癌的治疗提供新的思路。

The application of the Chinese version of the Body Image Disturbance Questionnaire in patients with systemic lupus erythematosus

This study aimed to translate the Body Image Disturbance Questionnaire (BIDQ) into Chinese and evaluate its reliability and validity in a sample of patients with systemic lupus erythematosus (SLE).Following the translation and revision of the Chinese version of the BIDQ, 169 patients with SLE were chosen as respondents to test the questionnaire''s reliability and validity. We tested the content''s validity through expert group evaluation. It is structural validity was examined through exploratory factor analysis and confirmatory factor analysis, and reliability was evaluated using Cronbach''s α and test-retest reliability.The Chinese version of the BIDQ showed a content validity of .92. A two-factor structure was revealed by exploratory factor analysis, which explained 67.83% of the variance and proved by confirmatory factor analysis. Its overall Cronbach''s α was .82 (P < .001), and the Cronbach''s α for each item ranged from .76 to .83. The test-retest reliability was .82, with the Cronbach''s α for each item ranging from .76 to .84.Thus, adequate reliability and validity of the Chinese version of the BIDQ were demonstrated for use in patients with SLE.     

Apoptosis of human pancreatic cancer cells induced by Triptolide

AIM： To investigate apoptosis in human pancreatic cancer cells induced by Triptolide （TL）, and the relationship between this apoptosis and expression of caspase-3＇ bcl-2 and bax. METHODS： Human pancreatic cancer cell line SW1990 was cultured in DMEM media for this study. MTT assay was used to determine the cell growth inhibitory rate in vitro. Flow cytometry and TUNEL assay were used to detect the apoptosis of human pancreatic cancer cells before and after TL treatment. RT-PCR was used to detect the expression of apoptosis-associated gene caspase-3＇ bcl-2 and bax. RESULTS： TL inhibited the growth of human pancreatic cancer cells in a dose-and time-dependent manner. TL induced human pancreatic cancer cells to undergo apoptosis with typically apoptotic characteristics. TUNEL assay showed that after the treatment of human pancreatic cancer cells with 40 ng/mL TL for 12 h and 24 h, the apoptotic rates of human pancreatic cancer cells increased significantly. RT-PCR demonstrated that caspase-3 and bax were significantly up-regulated in SW1990 cells treated with TL while bcl-2 mRNA was not. CONCLUSION： TL is able to induce the apoptosis in human pancreatic cancer cells. This apoptosis may be mediated by up-regulating the expression of apoptosisassociated caspase-3 and bax gene.     

Electrospun silk fibroin‐based neural scaffold for bridging a long sciatic nerve gap in dogs

Silk fibroin (SF)‐derived silkworms represent a type of highly biocompatible biomaterial for tissue engineering. We have previously investigated biocompatibility of SF with neural cells isolated from the central nervous system or peripheral nerve system in vitro, and also developed a SF‐based nerve graft conduit or tissue‐engineered nerve grafts by introducing bone marrow mesenchymal stem cells, as support cells, into SF‐based scaffold and evaluated the outcomes of peripheral nerve repair in a rat model. As an extension of the previous study, the electrospun technique was performed here to fabricate SF‐based neural scaffold inserted with silk fibres for bridging a 30‐mm‐long sciatic nerve gap in dogs. Assessments including functional, histological and morphometrical analyses were applied 12 months after surgery. All the results indicated that the SF‐based neural scaffold group achieved satisfactory regenerative outcomes, which were close to those achieved by autologous nerve grafts as the golden‐standard for peripheral nerve repair. Overall, our results raise a potential possibility for the translation of SF‐based electrospun neural scaffolds as an alternative to nerve autografts into the clinic.     

糖尿病心肌病影像诊断研究进展

糖尿病心肌病(diabetic cardiomyopathy,DCM)可导致糖尿病患者心力衰竭甚至死亡,是糖尿病的一种严重的并发症。早期表现为能量代谢、心肌脂肪变性、微循环灌注异常等,逐步发展为心肌细胞重塑、心功能异常和心肌纤维化等。DCM起病隐匿,致病分子机制尚未完全阐明,诊断标准不明确。目前可通过一些影像学检查间接检测心肌细胞可能存在的病理改变,做出诊断,及时干预,并监测病情发展,逆转或延缓病情,改善预后。本文就DCM病程中不同阶段的影像检测方法进行相关综述。
