There are three platinum catalyst micro channels which have different width ,such as 1000 m , 400m and 40m. The platinum catalyst micro channel reactor is fabricated by MEMS technology. The reactor uses the exothermic reaction of hydrogen and oxygen on the platinum catalyst plate as the heat source and the platinum thin film resistance deposited on a glass chip by face micro machining process as catalyst and temperature sensor. The channel is bonded with a cover plate etched by bulk micromachining technology to become a mico- channel reactor.

实验主要以微机电加工技术制作白金触媒微管道反应系统，利用微机电面型加工技术将白金薄膜电阻制作於基材为玻璃的晶片上，以此为反应所需的触媒及温度量测元件，并用体型加工技术蚀刻出微流道的上盖板相结合成微管道反应系统，本研究以1000μm、400μm及40μm的白金触媒微管进行测试，并利用微管道管壁上触媒表面降低反应活化能的特性来维持反应，此微反应系统利用氢气与氧气在白金触媒平板上的放热反应作为能量的来源。

To investigate the morphological changes of megakaryocytes with nuclear extrusion and nucleocytoplasmic separation, the morphological characteristics of megakaryocytes in peripheral blood films, bone marrow smears, and bone marrow biopsies from 4 newly diagnosed patients with primary myelofibrosis, myelodysplastic syndrome, myeloblastic leukemia with maturation (M2) and erythroleukemia (M6) were studied by using light microscope.

为了观察巨核细胞逸核和胞核胞质连体分离的形态学变化，用光镜观察4例初诊血液病患者的血片、骨髓涂片和骨髓切片中巨核细胞形态特征。4例初诊血液病患者为1例原发性骨髓纤维化，1例骨髓增生异常综合征，1例急性粒细胞白血病部分成熟型(M2)和1例红白血病(M6)。

Mutant mice than in wild-type controls, and tetrodotoxin or bicuculline application abolished the difference between the genotypes. Studies on human oligodendroglioma cells revealed that GABA played a protective role on Ca〓 overload induced by OGD or glutamate and phaclofen, GABA〓 receptor antagonist, could significantly block the protection.

结果表明：①电凝大脑中动脉后Ca〓2.3-／-鼠脑梗死率和缺血后运动障碍明显重于Ca〓2.3+／+鼠；②Ca〓2.3-／-鼠海马脑片CA1区缺氧后钙超载明显高于Ca〓2.3+／+鼠；③Na〓通道阻滞剂TTX和GABA〓受体阻断剂bicuculline可显著缩小遗传表型之间的差异；④GABA对缺氧无糖及谷氨酸所致的人胶质细胞瘤细胞Ca〓超载有明显的保护作用，此作用可被GABA〓受体阻断剂phaclofen拮抗。

Objective: To investigate the feasibility of swelling hydrogel instead of polyethylene oxide as swelling polymer in push-layer of push-pull osmotically controlled-release tablets.

中文摘要：目的：考察常用亲水膨胀材料替代聚氧乙烯作为推动层的膨胀推动剂用于制备推拉型渗透泵控释片的可行性。

Methods Seventy six aged patients with ostalgia caused by primary osteoporosis, whose T numerus less than certified value 2.5 were randomized into two groups: 1. Applying only CT (36 cases); 2. CT combined with Low frequency transduction pulsed electromagnetic fields (36 cases); Two groups simultaneously were given Calcium 600 mg and injected CT 50IU, ten days later injected 50IU every two days in two months, Low frequency transduction pulsed electromagnetic fields treatment was made by Tianjin Jinxitong company, frequency 20-40Hz, and treated 20 minutes by this machine, totally 30 days. Six months later we examined their Bone density again.

将存在骨质疏松性骨痛同时经DEXA骨密度仪检测T值低于标准值2.0以下的老龄原发性骨质疏松症患者76人随机分为两组：①单纯应用鲑鱼降钙素组（36人）；②联合应用药物及低频电磁场组（36人），两组同时每日给予钙而奇D600片1粒，CT按每日肌肉注射50IU，10d后改为隔日肌注50IU连续应用2个月，低频电磁场治疗采用天津金希统公司生产的XT2000B型OP治疗仪，频率为20~40Hz，每天治疗20min，共治疗30d， 6个月后复查骨密度。
