我国中药出口的现状与发展策略(Ⅱ)

2中药出口的发展策略2.1加快中药现代化步伐,走“以质取胜”道路2.1.1中药现代化是必由之路和长久之计科技兴贸表现在中药方面就是要促进中药现代化、标准化和规范化,吸收现代科学技术成果,提高中药产品的科技含量,这是中药打入国际市场并保持久盛不衰的前提和基础。中药生产企业要力求中药产品现代化,用高科技手段改造现有中药产品的生产工艺和品种,对中药产品加强定性定量分析,以符合国外医药法规的要求,扩大中药产品在欧美等发达国家的消费市场和消费群体。中药生产企业的GMP达标是与国际接轨的基础。目前,我国已有20多个中药生产厂家…     

视屏显示终端作业对人眼泪液分泌试验的影响

目的研究视屏显示终端(VDT)作业对人眼泪液分泌的影响,为保护VDT作业人员眼部健康提供科学依据。方法对185名VDT作业人员进行流行病学问卷调查、人眼泪液分泌试验及作业场所微环境检测。结果 VDT作业人员人眼泪液分泌试验异常率较高,且平均每日看电视时间长,显示屏—视线角度为平视、仰视,眼睛—显示器距离<20cm、视屏作业过程中不定时休息以及年龄等都是人眼泪液分泌试验的危险因素,而女性则是保护因素。结论应降低VDT作业人员的接触视屏时间,并在作业过程中做到定时休息,同时保证显示器—视线角度为俯视状态及足够的眼睛—显示器距离。

结肠绒毛状腺瘤X线表现

目的：研究结肠绒毛状腺瘤X表现的特点。方法：回顾性分析12例经手术病理证实的结肠绒毛状腺瘤的X线表现。所有病例均行低张双对比灌肠造影。结果：该组病人中，病变主要位于直肠、乙状结肠占75％。绒毛状腺瘤X线主要征象：所有病例均显示，腔内突出的肿块充盈缺损（100％），肿块表面不规则分叶，结节状隆起及细网状结构。3例肿块表面可见溃疡。结论：X线表现反映了结肠绒毛状腺瘤的病理特点。因此低张双对比满足肠造影对结肠绒毛状腺瘤具有很高诊断价值。     

生长激素雌激素对去势大鼠剩余牙槽骨内IGF-I表达的影响

目的观察生长激素、雌激素及两者联合运用对切除卵巢大鼠剩余牙槽骨内胰岛素样生长因子分布和表达的影响。方法通过去除SD大鼠双侧卵巢,拔除单侧上颌磨牙,建立骨质疏松的剩余牙槽骨动物模型,并在此基础上通过免疫组化方法观察、分析切除卵巢及单独和联合运用生长激素、雌激素对去势大鼠剩余牙槽骨内胰岛素样生长因子分布和表达的影响。结果骨质疏松组局部牙槽骨内的IGF-I表达最弱,雌激素、生长激素以及两者联合运用都能通过增加IGF-I在骨组织局部的表达量提高成骨的活性,检验有统计学意义（P〈0.05）。生长激素及联合用药的效果优于单独运用雌激素,联合用药组提高IGF-I表达的效果略高于单用生长激素组,但无统计学意义（P〉0.05）。结论雌激素、生长激素及两药联合运用能通过增加IGF-I表达延缓牙槽骨吸收。

内固定应用于脊柱结核治疗的安全性探讨

Objective To investigate the efficiency and safety of instrumentation to treat spinal tu-berculosis. Methods Fifty-one patients of spinal tuberculosis were treated with one-stage or two-stage de-hridement, strut autografting, and anterior or posterior instrumentation with screw rod system, combined with one-year triple agents postoperative antituberculous chemotherapy from April 1985 to May 2005. There were 6 in cervical spine, 19 in thoracic spine, 16 in thoracolumbar spine and 10 in lumbosacral spine. The level of the lesion were 6 cases for single vertebrae, 30 for two vertebrae, 11 for three vertebrae and 4 for more than four vertebrae. All patients were given triple agents antituberculous chemotherapy at least two weeks before operation. The operative procedures included cervical anterior approaches in 6 cases for debridement, fusion and plate-screw fixation, upper lateral transthoracic procedures for debridement, fusion and screw rod fixation in 11, posterior debridement, fusion and transpedicular screw system fixation in 6, two-stage anterior and posterior operation in 18 cases. The instrumentation included 6 Luque, 3 Z-plate, 8 TSRH, 5 Ventrofix, 4 Kenada, 5 Moss-Miami, 6 Isola, 3 CDH, 2 Caspaz, 2 C-D, 1 Zielke, 1 Dick, 1 Oriell, 1 Ozion, 1 Zephir, 1 Tenor, and 1 USS. Results All patients were followed up prospectively for 3.2 to 23.5 years postoperatively. The back pain was obviously relieved postoperatively. Patients with neurological function deficiency im-proved. The solid fusion was achieved in all patients, except one patient due to tuberculosis recurrence. The major complication included one sinus formation and one case with temporary deterioration of neurological function, recovered with appropriate treatment. Average preoperative kyphosis angle was 34.17°, and that was 10.45° immediately after surgery. There was a 3.2° loss of kyphosis correction during follow-up period. Con-clusion Spinal tuberculosis treated with instrumentation is effective and safe.
