不同浓度5-溴脱氧尿嘧啶核苷标记山羊骨髓基质干细胞的体外研究

Objective To explore the feasibility of labeling and tracing in vitro goat bone marrow mesenchymal stem cells (BMSCs) by bromodeoxyuridine (BrdU) on the basis of investigation of its optimal concentration, incubating time and cytotoxicity. Methods A healthy goat, aged 10 months old, male, weighing 32 kg, was used in this study. Bone marrow was aspirated. BMSCs were isolated and cultured using the adherence method in vitro. The fourth passage of BMSCs (P4) were incubated with BrdU at 5, 10, 15, 20 μmol/L as 5, 10, 15, 20 μmol/L BMSC groups. Cells were not labeled by BrdU as negative control. The following parameters were measured: induction, differentiation and determination of goat BMSCs; the optimal mass concentration and incubation time of 5-BrdU labeling; cell positive rate at 12, 24, 48 and 72 hours in each group using immunofluoreseenee; the cell survival rate after various concentrations of BrdU ladling by trypan-blue exclusion. Results The morphology of the primary and passage goat BMSCs was fusiform in shape. Goat BMSCs could differentiate into osteoblasts and chondrocytes following induction. BMSC nucleus showed green fluorescence under fluorescence microscope after being labeled by BrdU. The mean labeling rate increased with the increase in the concentration and incubation time of BrdU, and reached to (93.32± 3.25)% after incubation in 15 μmol/L, BrdU for 48 hours. There were no significant differences between 15 μmol/L BrdU for 72 hours, 20 μmol/L BrdU for 48 hours and 72 hours (P > 0.05), or between the other groups or time points (P < 0.05). The labeling rate of the blank control group was 0. The cell survival rate was all above 90% (P > 0.05). Conclusions BrdU can be used as a labeling marker for goat BMSCs. When the concentration is 15 μmol/L and the incubation time is 48 hours, the optimal labeling effect can be achieved. Goat BMSCs labeled with BrdU is of high efficiency and safety.     

慢性肾脏病非透析患者脑钠素与动脉粥样硬化及心功能的关系

目的 研究脑钠素（BNP）与慢性肾脏病（CKD）非透析患者动脉粥样硬化及心功能不全的关系。 方法 采用双抗夹心免疫荧光法检测203例CKD非透析患者与16例高血压患者对照组全血BNP水平，分析其与颈动脉超声结果、心脏彩超结果及既往心血管疾病史的关系。 结果 CKD非透析患者BNP水平与对照组相比显著升高[M（范围）：54.40(15.10～ 173.00) ng/L比9.35(7.35～15.00) ng/L，P < 0.01]。Spearman相关分析显示CKD患者BNP与颈动脉内膜中层厚度（IMT）、左室心肌重量指数（LVMI）等呈正相关。存在颈动脉斑块、左室肥厚或既往发生过心血管事件的患者血BNP水平显著增高。多元回归分析显示LVMI、既往心血管事件均是影响BNP水平的独立因素。 结论 CKD非透析患者BNP水平和动脉粥样硬化性疾病、左室肥厚及心功能不全相关，提示BNP水平可作为一项评价CKD非透析患者心功能及动脉粥样硬化的敏感生物学指标。     

Clinical applications of mifepristone.

Mifepristone is a progesterone antagonist that has been studied for a number of clinical applications. It is a well-known abortifacient that is effective for both first- and second-trimester medical abortion when used with a prostaglandin analog. It is also an effective cervical priming agent that can be used to soften the cervix before surgical evacuation. Its clinical efficacy as an emergency contraception has been proven. Other applications including treatment for fibroids, endometriosis and various cancers have been explored. However, its association with abortion limits the applications of mifepristone in many of these areas.     

胃癌和大肠癌患者血清肿瘤标志物联合检测的临床意义

目的评价血清肿瘤标记物联合检测对胃癌和大肠癌诊断和监测的价值.方法用PC-12多种肿瘤标志物蛋白芯片检测系统检测179例胃癌和大肠癌患者、82例胃和结直肠良性疾病患者及160例健康人血清中12种常见肿瘤标志物CA19-9、NSE、CEA、CA242、铁蛋白（Ferritin）、Beta-HCG、AFP、free-PSA、PSA、CA125、HGH、CA153的水平.结果肿瘤组的肿瘤标志物水平显著高于良性疾病组及健康组（P＜0.01）,其中CA19-9、CEA、CA242、CA125和CA153 5项在胃癌和大肠癌患者中水平较两对照组明显升高,差异有统计学意义（P＜0.01）.采用平行检测法,可以提高检测的敏感度（72.07%）和阴性预测值（79.25%）;采用系列检测,可提高检测的特异度（92.15%）和阳性预测值（84.67%）.肿瘤根治术后,肿瘤标记物水平显著下降.术后未降至正常者,复发或转移率为68.89%,而术后再升高者复发或转移率为77.78%.结论多种肿瘤标记物对胃癌和大肠癌的诊断、监测肿瘤复发和转移有一定的价值.

喉咽癌手术放疗后甲状腺功能减退

本文对４２例喉咽癌手术及放疗后患者甲状腺功能的变化的初步探讨表明：在治疗结束后不同时间内有５７．１％的患者Ｔ４降低及（或）ＴＳＨ升高，其中放疗结合甲状腺部分切除者其发生率高达７３．９％，而未行甲状腺部分切除者仅３８．５％，两者呈显著差异（Ｐ＝０．０３）。术前或术后放疗对甲状腺功能影响较小，亦无明显差异。发生时间在治疗结束后２年内尤其在１年左右为多见。
