目的：探讨血管内皮生长因子受体VEGFR－2在儿童髓母细胞瘤中的表达及临床意义。方法：采用免疫组化LSAB法检测84例获随访的儿童髓母细胞瘤中的VEGFR－2表达，按术后生存期3，5，10年分为A，B，C三组，使用Cox回归统计分析。结果：84例儿童髓母细胞瘤中，VEGFR－2阳性表达74例（88．09％），A，B，C三组间VEGFR－2阳性表达分别为100％，88．89％，55．33％（P＜0．01），Cox回归分析显示VEGFR－2是影响生存时间的一个独立的预后因子，它与预后存在负相关关系。结论：VEGFR－2表达水平可作为儿童髓母细胞瘤的预后指标之一。     

止痛化癥胶囊联合亮丙瑞林治疗子宫内膜异位症的疗效观察

目的 探究止痛化癥胶囊联合亮丙瑞林治疗子宫内膜异位症的临床疗效。方法 选取2014年1月-2014年7月鄂州市中医医院妇产科收治的子宫内膜异位症患者98例,随机分为对照组和治疗组,每组各49例。对照组皮下注射注射用醋酸亮丙瑞林微球,3.75 mg/次,4周/次,若患者体质量<50 kg,则注射剂量减少50%。治疗组在对照组基础上口服止痛化癥胶囊,4粒/次,2次/d,月经期间停止服用。3个月为1个疗程,连续治疗2个疗程。观察两组的临床疗效,同时比较两组治疗前后促卵泡生成素(FSH)、黄体生成激素(LH)、雌二醇(E₂)、子宫体积、CA₁₂₅、Kupperman评分的变化。比较两组患者绝经症状发生情况。结果 治疗后,对照组和治疗组的总有效率分别为77.55%、91.84%,两组比较差异具有统计学意义(P < 0.05)。治疗后,两组FSH、LH、E₂、子宫体积、CA₁₂₅水平、Kupperman评分均显著降低,同组治疗前后差异具有统计学意义(P < 0.05);且治疗组这些指标的降低程度优于对照组,两组比较差异具有统计学意义(P < 0.05)。治疗组潮热出汗、感觉异常、失眠、情绪波动、抑郁、眩晕、疲乏、骨关节痛、头痛、心悸、皮肤蚊走感、泌尿感染、性生活障碍发生例数均显著低于对照组,两组比较差异具有统计学意义(P < 0.05)。治疗后,两组患者痛经、盆腔痛、性交痛的VAS评分均显著降低,同组治疗前后差异具有统计学意义(P < 0.05);且治疗后,治疗组痛经、盆腔痛的VAS评分低于对照组,两组比较差异具有统计学意义(P < 0.05)。结论 痛化癥胶囊联合亮丙瑞林治疗子宫内膜异位症具有较好的临床疗效,可降低患者FSH、LH、E₂水平和VAS评分,改善患者绝经症状,具有一定的临床推广应用价值。     

Repair effect of Schwann cells modified by microgene pSVPoMcat on injured spinal cord in rats

OBJECTIVE: To observe the repair effect of Schwann cells (SCs) modified by microgene pSVPoMcat on injured spinal cord in rats. METHODS: Semi-transection injury at the level of T(8) of spinal cord was made with cutting method on 120 Sprague Dawley (SD) rats. Then 40 rats implanted with SCs modified by microgene pSVPoMcat were taken as Group A, 40 rats implanted with simple SCs as Group B and the other 40 rats were taken as the control group (Group C). The functional recovery of the rats was observed through combined behavioral score (CBS) and cortical somatosensory evoked potential (CSEP), and the expression of the glial fibrillary acidic protein (GFAP) was measured with in situ hybridization and immunocytochemistry. At 3 months after operation, the rats were examined with magnetic resonance image (MRI), and the neurofilaments (NF) of the axons were stained with immunohistochemical method. RESULTS: GFAP expression in Group A was significantly lower than that of the other 2 groups. MRI showed that the spinal signals in the injured area recovered fundamentally in Group A, didn't recover in Group B and malacia focus was found in Group C, which was same as the results of NF staining. Wave amplitudes in incubation periods in Group A and Group B tended to recover. It recovered to the normal level in Group A, which was similar to the results of CBS. CONCLUSIONS: SCs modified by microgene pSVPoMcat can inhibit GFAP expression, improve the growth of the axons and the functional recovery of neurons after spinal cord injury.     

儿童髓母细胞瘤Bcl-2基因表达的研究

目的 检测髓母细胞瘤的凋亡情况,并分析其与肿瘤恶性增殖和预后的关系。方法 以84例获随访的儿童髓母细胞瘤组织（按术后生存期<3年、3-5年、5-10年分为A、B、C3组）为研究对象,用原位杂交及免疫组化染色法分别检测Bcl-2 mRNA和增殖细胞核抗原（PCNA）的表达,并用3末端标记法做原位细胞凋亡检测。结果 72例（85.7％）表达Bcl-2 mRNA,A、B、C组阳性率分别为100％、88.9％、40％,彼此之间阳性率差异显著（P<0.05）。PCNA阳性细胞密度随Bcl-2 mRNA表达增强而增高,而凋亡细胞密度随Bcl-2 mRNA表达增强而减少。结论 儿童髓母细胞瘤中 Bcl-2基因高表达可抑制其凋亡,这可能是瘤细胞恶性增长的重要原因之一。

pSVPoMcat微基因修饰许旺细胞移植对脊髓损伤的早期保护作用

业已证实将许旺氏细胞（Ｓｃｈｗａｎｎｃｅｌｌ,ＳＣ）移植到损伤的中枢神经系统后能够促进神经的再生、脊髓的重建和部分功能的恢复。然而,移植的ＳＣ功能低下,存活时间短,有必要进行基因修饰细胞的移植［１,２］。髓鞘碱性蛋白（Ｍｙｅｌｉｎｂａｓｉｃｐｒｏｔｔｅｉｎ,ＭＢＰ）基因的异构体２１５ＫＤＭＢＰ基因不仅在胚胎发育早期的神经元表达特别强,而且在胚胎早期成熟神经元中也有表达,能参与髓鞘的发生与形成［３］。因此,我们在国际上首次构建成人Ｐｏ蛋白５’侧端介导的２１５ＫＤｈＭＢＰ微基因（暂命名（ｐＳＶＰ…

Effect of Microgene pSVPoMcat Implanted to Modify Genetically Schwann Cells on Apoptosis After Spinal Cord Injury

Recent years, with the advancement of molecular biology, it has been recept that cell apoptosis is the result of gene expression and is regulated by extracellular factors.Crowe et al[1]have demonstrated in their study that cell apoptosis and necrosis coexsisted and both exacerbated CNS injury after CNS was injured. Many experiments showed that large amount of apoptosis proved that cell apoptosis is the key to secondary injury after SCI.Secondary degeneration and chrocic demyelination are c…
