小儿先天性肺囊肿周边肺发育的观察及其临床价值

目的 探讨先天性肺囊肿(CBC)与肺发育不全的关系及其外科治疗。方法 32例CBC患儿和18例正常对照，分别测量肺泡辐射状计数(RAC值)及单位视野内第6级以上肺小动脉数(A值)。行肺小动脉Gomori醛复红弹力纤维染色；随访病例复查胸片，测量TLC、VC。结果 CBC组RAC值及A值低于正常对照，支气管型CBC的RAC值低于肺泡型；肺小动脉内、外弹性膜可见多处断裂，管壁平滑肌变性及肥厚；随访囊肿摘除及肺叶切除术后TCL、VC分别为对照的97％—98％、85％～90％。结论 CBC导致周边肺发育不全，宜尽早手术摘除。     

Examples of Clinical Application of Multiple Needling in Neijing in Treating Bi Syndrome

Ling Shu (< 灵枢 >) said, "The essentials of acupuncture lie in the needling techniques."Twenty-six needling techniques recorded in it, such as the "Nine Needling Techniques", "Five Needling Techniques" and "Twelve Needling Techniques",were cried up by the acupuncture doctors in the past dynasties. The authors applied the relevant needling techniques to treat Bi syndrome in clinic and the quite good effects were got.     

乌鲁木齐市2000-2004年法定传染病报告质量调查分析

目的为了及时准确地掌握各类传染病的漏报情况，为制订传染病防治策略提供理论依据。方法每年对区、市、系统、乡级医疗机构疫情报告情况进行调查，计算漏报率。结果共调查传染病患者4069例，漏报130例．总平均漏报率为3．19％。年漏报率最低为0．53％；最高为10．39％。漏报病种最高为细菌性痢疾和病毒性肝炎．分别占总漏报数的53．85％和26．15％。结论领导重视、提高业务人员的能力和基层防保队伍的建设，是传染病疫情报告和管理工作顺利开展的保证。     

蛋白酶体功能障碍对多巴胺能PC12细胞的特异性损伤

目的探讨蛋白酶体抑制剂lactacystin对多巴胺能PC12细胞的特异性损伤。方法不同浓度的lactacystin(1、5、10、15和20μmol/L)分别处理多巴胺能PC12细胞和胶质瘤U251细胞24 h,MTT法检测细胞活力;50μmol/L的lactacystin处理U251细胞24 h,MTT法检测细胞活力;10、20μmol/L lactacystin处理PC12细胞,W estern B lot检测细胞内多泛素化蛋白含量;单胺氧化酶B抑制剂selegiline(500μmol/L)和特异性酪氨酸羟化酶抑制剂-αMT(1 mmol/L)提前4 h预处理PC12细胞,再与10μmol/Llactacystin共同作用24 h,MTT法检测细胞活力,W estern B lot检测多泛素化蛋白含量。结果Lactacystin呈剂量依赖性损伤多巴胺能PC12细胞,其对胶质瘤U251细胞无毒性作用,而且其毒性与细胞内多泛素化蛋白生成增加相关。用以增加细胞内多巴胺含量的selegiline和用以减少细胞内多巴胺含量的α-MT都导致lactacystin毒性增强。结论蛋白酶体功能障碍特异性损伤多巴胺能细胞,而其特征性的神经递质多巴胺在其易感性中的作用复杂。

Modification of C.I. Pigment Red 146 with surfactants and graphene oxide

Organic pigments are important in a range of fields, from printing ink to industrial coatings. Azo pigments are some of the most common pigments in use today, but they typically have poor solvent solubility and tend to agglomerate. Consequently, the size and crystal structure of the pigment particles has a crucial effect on their optical and physical properties, such as color strength and solvent resistance, respectively. Several technologies, such as microreactors, have been developed to control pigment particle size, but an in-depth study of the effects of modification conditions on pigment properties (color, flowability, and solvent resistance) has not been reported to date. Therefore, in this paper, we report the surface modification of C.I. Pigment Red 146 particles using anionic (Igepon T) and non-ionic surfactants (Peregal O-25) and additives (DB-60 as the second diazo component and graphene oxide) on the pigment properties. In addition, we examined the effect of hydrothermal treatment at different temperatures on the same properties. The various modifications resulted in an increase in the solvent resistance, a reduction in the particle size (from 30.581 to 12.252 μm), a narrowing of the particle size distribution, and an increase in hydrophilicity. In addition, the color brightness and brilliance were significantly improved, and the maximum color strength reached 112.6%. These findings have applications for the development of pigments having enhanced color properties, solvent resistance, and processability.

The color properties and solvent resistance of modified Pigment Red 146 were obviously improved by adding surfactants and graphene oxide.     

局部植入BMP对去势大鼠股骨近端生物力学强度及髓腔面积变化的影响

目的探讨去势大鼠股骨近段植入牛骨形成蛋白(bone morphorgeneic protein,BMP)后其骨生物力学强度及髓腔面积的变化。方法随机选取6月龄wistar雌性大鼠22只,摘除卵巢制作绝经后骨质疏松模型成功后,同一只动物双侧肢体对照,试验侧股骨颈植入牛骨形成蛋白及纤维蛋白(FS)复合物,对照侧植入纤维蛋白,术后4周、8周处死取材,测量股骨近端生物力学强度及髓腔面积和截面面积。结果4周后,试验侧与对照侧股骨近端骨生物力学强度和髓腔面积无明显差异;8周后,试验侧股骨近端生物力学强度较对照侧增高;髓腔面积较对照侧有较明显的减小(P<0.05)。结论股骨近端局部植入BMP可提高去势大鼠股骨近端局部的生物力学强度和减小近端髓腔面积和截面积,其可能减少骨质疏松性髋部骨折置换后假体的松动,成为骨质疏松性骨折假体置换中新的辅助治疗方法。
