According to the observation of the microstructure of small diameter lumber with scan electron microscope, there are many bordered pits of the radial trancheidal wall in the small-diameter Larch, and most of them have pit film. The resin is not only in resin canal, but also in some trancheid and ray parenchyma cells. The drying defects of small-diameter Larch lumbers were the most severe in consecution heating, fluctuating-heats 2h in between, and drying defects were nearly not observed in fluctuating-heats 6h. There is tylosis in the vessel of the heartwood of small-diameter Cathay poplar. The bordered pits of the radial trancheidal wall are dense, and the pits between vessels are alternate, most of them have pit film. Different collapse happened in all the small-diameter Cathay poplar lumbers. The collapse of small-diameter Larch lumbers was the most severe with consecution heating, fluctuating-heats 2h in between, the least with fluctuating-heating 6h.

通过扫描电镜观察发现，小径木落叶松的径壁具缘纹孔数目较多，且多具纹孔膜，小径木落叶松除在树脂道中含有树脂外，在一部分管胞胞腔内以及一些木射线细胞中也含有树脂，在产生缺陷的小径木落叶松锯材中，连续加热方式下锯材的开裂缺陷最为严重，波动2时次之，波动6时几乎没有开裂现象；小径木大青杨心材导管中的层状浸填体含量较多，且径壁具缘纹孔较为密集，管间纹孔呈互列方式，绝大多数纹孔具有纹孔膜，干燥后的小径木大青杨锯材均有不同程度的皱缩现象产生，其中连续加热干燥试验锯材的皱缩现象最严重，波动2时次之，波动6时干燥试验锯材的皱缩缺陷最小。

130 rats were randomly divided into five groups: 5F electroacupuncture treatment group, 50Hz electroacupuncture treatment group,100Hz electroacupuncture treatment group, the model group and the control group. 4mm defect was produced in the left sciatic nerve of each rat and silicon nerve guards were used to bridge the nerve defect not including the rats of the control group. After 10 weeks electroacupuncture treatment, gross observation, histological examination of the sciatic nerve were carried with method of HE stainning and S-100 immunhistochemical staining, Sevier-Munger stainnning. The histomorphometric examination of the triceps muscles were observed with measuring width muscle cell and the wet weight, and measuring the content of the heparin and the lactic aid of the triceps muscle with biochemistry methods.

实验方法：将130只Wistar大鼠随机分为五组：正常组、造模组、电针5Hz组、电针50Hz组、电针100Hz组，除正常组外，其余各组手术切取坐骨神经4mm后，做坐骨神经硅胶管桥接术，造成周围神经损伤模型，取患侧足三里、三阴交、环跳穴，术后第四天开始电针，每两天一次，每次10分钟，治疗10周后处死动物，取出硅胶管内新生的坐骨神经，纵切片，HE染色、S100免疫组化染色、Sevier-Munger银染，观察坐骨神经纤维再生情况，以健侧同段坐骨神经做对照；取患侧脖肠肌称取湿重，HE染色，观察腓肠肌肌细胞直径，生化测量腓肠肌肌糖元、乳酸。

Comparison of genes in yolk sac cells with a total of 1 200 genes in the control cells, 79 genes differently expressed between the two groups were detected.

中枢神经系统中的apoE对脑组织淀粉样蛋白的沉积与清除、微管蛋白稳定性的维持、细胞信号转导、免疫调节、葡萄糖代谢、氧化应激等都有潜在的作用，apoE在体内发挥十分重要的生物学活性。

Methods After treating 147 teeth which diagnosed as aschronic apicitis were suitable for root canal therapy,divided at random into three groups:0.5% Anerdian treatment group,FC group and dry cotton spill to seal the root canal of them.

结果 安尔碘作为根管消毒药物治疗根尖周疾病效果与FC相比差异无显著性，而FC对机体组织有一定刺激性和细胞毒性，且部分患者会过敏。

The score of renal calcium oxalate crystallization of 12%,25% medlar soak and apozem was reduced 38.7%, 54.8% and 48.4%, 58.1%(P.01) compared with the ethylene glycol drinking group. Conclusions: LBP can reduce the formation of renal calcium oxalate crystallization. The mechanism is to protect from damage by free radical and reduce the apoptosis of renal tubular epithelial cell by hyperoxaluria.
