Methods We adopted four methods that single cpidural block anesthesia or narcotics analgesies were injected into subarachnoid space and epidural space or single narcotics was injected into subarachnoid space (group C fentanly 25μg;group D fentanly 20μg) to study analgesia birth for 130 nullipara women. The analgesia efficacy, side effect, birth time md mode,postpartum haemorrhage and the condition of the fetus and the newborn were compared.

No entire nitrendipine crystals were observed visually in SEM photos. The results of X-ray diffraction and differential scanning calorimetry analysis indicated that the crystalline form of nitrendipine was highly dispersed in microspheres, so as amorphous state. The drug release rate of microspheres could be controlled with adjusting the ratio of solid dispersion carriers and retarding agents formulated. The agitation speed and temperature of the preparation process have distinct effect on micromeritic properties of microspheres. The release profiles of the microspheres were mainly affected by the stirring rate of paddle, the concentration of SDS and pH of dissolution medium. Cooling speed and time, however, have no evident influence on the drug release rate of the microspheres. The dissolution data showed that the mechanism of drug release from microsphers was mainly diffusion-controlled. The incorporation efficiencies of 3 batches sample were exceed 96. 8％, which implied that the current method was suitable for design sustained-release dosage form for poorly water-soluble drug.

在扫描电子显微镜下观察，在微球内外未发现尼群地平的完整结晶，X-射线粉末衍射和差示扫描量热试验结果也显示，尼群地平已经被高度分散在微球中；微球的释药速度可通过调整处方中固体分散体载体和阻滞剂的比例控制；制备温度和搅拌速度对微球的质量影响较大；溶出仪的搅拌速度，释放介质的浓度和pH对微球的释放有较大的影响；制备过程中的冷却速度和冷却时间对微球的释放行为影响不很明显；方程拟合的结果表明缓释微球的释药行为符合扩散机制；测定三批微球样品的包封率均在96.8％以上，表明该法适合于制备难溶性药物的缓释微球。

JPYFHY Recipe can inhibite the tumor of lung cancer transplanted animals, and the JPYFHY Recipe drug-serum can block the prolife ration of A549/DDP in vitro by inducing cancer cell apoptoses and boking cell cycle; It can enhance the chemotherapy synergism effects when they are used in combination and reverse multidrug resistance which because of DDP. The mechanism of these reversing drug resistance maybe is related to downregulating the expression of MRP and GST and upregulating the expression of TopoⅡ.
