某化工厂甲醇作业工人健康检查结果

为了解甲醇的职业危害，我所于2006年对某化工厂甲醇作业环境进行了现场调查，并对作业工人进行了健康检查。现将结果报告如下。

戊四氮诱发大鼠全身强直-阵挛性癫痫发作诱导丘脑c-fos癌基因表达

首次运用Fos癌蛋白抗体免疫组化法详细研究了戊四氮诱发大鼠全身强直-阵挛性癫痫发作诱导丘脑c-fos癌基因表达的动态分布。主要结果是:腹腔内注入戊四氮诱导大鼠癫痫发作后0.5h,丘脑室旁核出现低密度的Fos-免疫阳性(Fos-ir)细胞核标记;3h时,中等密度的Fos-ir标记扩布至大部分丘脑中线和板内核群及网状核;6h时,所有上述丘脑核群的Fos-ir标记普遍增为中等至高密度。结合文献报道,上述结果提示:丘脑室旁核很可能是戊四氮诱发大鼠全身强直-阵挛性癫痫发作的重要起源部位之一;丘脑中线和板内核群及网状核很可能在此种癫痫发作的病理生理机制中起重要作用。     

γ-Pyrone Compounds as Potential Anti-cancer Drugs

Abstract— The γ-pyrones, artomunoxanthotrione epoxide, cyclocommunol, cyclomulberrin, and cyclocommunin exhibited potent inhibition of human PLC/PRF/5 and KB cells in-vitro. Dihydroisocycloartomunin showed significant and potent inhibition of human PLC/PRF/5 and KB cells in-vitro, respectively. Cyclomorusin, dihydrocycloartomunin and artomunoxanthone showed significant inhibition of KB cells in-vitro. Based on the above finding and the reported antileukaemic activity of xanthone psorospermin, a series of natural γ-pyrones was prepared and the inhibition of human PLC/PRF/5 and KB cells in-vitro was measured. Structure-activity analysis indicated the epoxide group substituted at 3-hydroxyl and 2,6-; 3,6-; and 3,5-dihydroxyl xanthone enhanced the anti-tumour activity. The epoxide group substituted at the 6-hydroxyl group of 1,6-dihydroxyxanthone did not show anti-tumour activity.     

Comparative study on healing process between vascularized and non-vascularized autogenous bone grafts]

This study made a histological comparison (light microscope and transmission electron microscope) between vascularized bone graft (VBG) and non-vascularized bone graft (NVBG) in mandible of dog.The study showed:the healing process of VBG was the same as that of bone fracture.The "creeping substitution" process of NVBG was imbued with the inflammation induced by dead bone.There was no significat difference on the bone union between VBG and NVBG perhaps for the recipient region was better vascularized.     

米氮平治疗神经性厌食症的疗效对照研究

目的：观察米氮平对神经性厌食症的疗效。方法：42例符合CCMD-3神经性厌食症患者被随机分成2组，分别给予米氮平和5-羟色胺再摄取抑制剂（SSRIs）治疗12周，而后随访12周。比较患者治疗前后的体重变化、汉密尔顿抑郁量表（HAMD）和汉密尔顿焦虑量表（HAMA）评分及药物不良反应。结果：共38例患者完成治疗全过程，其中米氮平组20例，SSRIs组18例。在治疗6周时，米氮平组的体重增加大于SSRIs组，差异有显著性（P〈0．01）；治疗12周时，两组体重增加值差异没有显著性。治疗后两组HAMD和HAMA评分均明显减低（P〈0．01），但两组间差异无显著性（P〉0．05）。两组均未出现严重的药物不良反应，主要不良反应SSRIs组为胃肠道不适，米氮平有嗜睡、体重增加等。结论：米氮平能明显提高神经性厌食症患者的食欲和体重，改善焦虑抑郁情绪，依从性好，起效时间早于SSRIs，值得在临床上选用。     

白细胞介素—1对大鼠下丘脑室旁核Fos癌蛋白和CRF的诱导作用

将白细胞介素-1(IL)注入大鼠侧脑室,用Fos癌蛋白抗体免疫组化法检测了下丘脑室旁核的激活神经元:大量位于含促肾上腺皮质激素释放因子(CRF)相应区域的室旁核小细胞部神经元呈Fos免疫强阳性。Fos和CRF的免疫双染色显示了许多Fos免疫阳性神经元也呈CRF免疫阳性。此外,在IL-1注射动物中,CRF的免疫阳性显著加强,提示CRF合成增加。
