In recent years,with the rapid development of orthopedic surgery and minimally invasive surgery,superficial fascia and its structures are receiving much recognition and more and more attention.Although opinions on naming and definition at different levels still vary,in-depth study of related structures offers clinical surgeons a broad prospect.

The necessity and performing method of research-intensive teaching in microbiology experiments are explored in the aspects of teaching design, process and effect. It is concluded that research-intensive experiments plays a positive role in developing students’comprehensive quality.

The (GCT)o polymorphism of the MICA gene was investigated in 100 patients with latent autoimmune diabetes in adult (LADA) and 145 healthy controls by PCR and denaturing polyacrylamide gel electrophoresis.The A5.1 allele was present at a significantly higher frequency in LADA group (0.340) than that in control group (0.183) (P

Since the laparoscopic thyroidectomy carried out in China for ten years,this technique has become more and more mature,indications gradually broadened,and playing a vital role in the field of thyroid surgery.This article will explain this technique in the aspects of approaches,the establishment and maintenance of the surgical space,indications,antiindications and complications.

With the development of industrialization,the problem of oil-contamination to the soil is getting more and more serious.How to clear up or remove the oil-contaminants from the soil becomes an important environmental problem for all countries around the world.Bioremediation,as the methods with fast and safe in processing,low cost and non-secondary contamination,is becoming the main solution to soil environment by oil contamination.Biostimulation and bioaugmentation are most commonly used techniques in bioremediation.The theory of bioremediation,including the concept and method of biostimulation and bioaugmentation were introduced,and advance study and progress in this field from the world in recently years were demenstrated.Both of the two methods can lead a significant decrease in soli TPH content,but the efficiency relates to many factors.Accordingly,the bioremediation technique should be tailored specifically to each polluted site.

By using cup culture, influence of different strains (ammonium-resistant N2-fixing type, wild type, none N2-fixing type) of Klebsiella oxytoca on the growth of rice seedling was compared. It was discovered that ammonium-resistant N2 -fixing bacteria could excrete some plant growth promoting substance, which could be adsorbed by cation resin. It' s activity wouldn't be affected at 80℃. At optimal concentration, the weight of rice root and seedling were increased by

0.05). But there was more BMP in the treated group of periodontitis than the other groups(P

Objective:To Study the effect of static magnetic field on the proliferation and differentiation of osteoblasts.Methods:In vitro cultured rat calvarial osteoblasts were seeded into 96-well culture plate and exposed to the different magnetic intensity field for 24,48 and 72 h respectively.MTT assay was applied to study the cell proliferation. ALP was measured by a microplate reader.Results:When the magnetic exposure time extended to 48 h or 72 h, the corresponding MTT value of osteoblasts with magnetic treatment of 40 mT or 62 mT increased obviously(P0.05). ALP activity increased after 24 h exposure to static magnetic field, the effect of static magnetic field intensity of 62 mT and 83 mT showed the strongest promotion effect(P
