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

BACKGROUND: Measurement is frequently performed in diagnosis of orthopedics, and involved in various correction andtreatment of congenital and acquired deformity. The perioperative measurement of affected knees of patients undergoing totalknee replacement (TKR) is significant.OBJECTIVE: To clinically evaluate and validate 4 domains of a self-designed simple medical orthopedics tool measurementapparatus (OTMA) according to the results of Cybex Norm measurement system, an international standard measurementapparatus, for osteoarthritis patients during TKR.DESIGN, TIME AND SETTING: Stratified, randomized, Controlled experiment. The study was performed at the Department ofOrthopedics, Peking Union Medical College Hospital between October 2004 and March 2006.PARTICIPANTS: A total of 47 patients (66 knees) with osteoarthritis of knee, undergoing TKR, were selected and randomlydivided into 2 groups: OTMA group (n=24, 33 knees) and Cybex group (n=23, 33 knees).METHODS: Range of motion (ROM) of two groups was measured respectively using OTMA and Cybex Norm, before and 3months after treatment as well as the final time of 1-year follow up. The ROM results were evaluated by Hospital for SpecialSurgery Knee Score (HSS) scale for knee joint. The visual analog scale and MOS 36-item Short Form Health Survey (SF-36)scale were filled to verify the applicability and reproducibility of OTMA. The correlation of measurement results and subjectivescale evaluation was analyzed to verify the evaluation efficiency of OTMA.MAIN OUTCOME MEASURES: Coincidence of ROM of two groups at different time points; correlation of scale scores and ROM.RESULTS: All patients were followed up. The coincidence rate of measurements between OTMA and Cybex Norm was 98.3%,HSS scale scores were increased with increasing ROM in both groups (P < 0.01). Correlation analysis showed that ROM washighly correlated with scale results, consistent with the clinical manifestation of patients.CONCLUSION: The measurement process was accepted by all patients, and could be performed repetitively. OTMA displaysprecise measurement, which could reflect clinical symptoms of patients and assist clinical diagnosis.

Objective To investigete the changes of neurons in cortex and hippocampus of spontaneously hypertensive rat.Methods Systolic pressure,diastolic pressure and mean arterial pressure,heart rate were measured by caudal artery manometry in six-month old SHR and age-matched Wistar rats(control group).Neurons in frontal lobe,parietal lobe,temporal lobe,and hippocampal CA1,CA3 sub-field and the dentate gyrus were observed through Nissl staining.Results Systolic pressure,diastolic pressure and mean arterial pressure in SHR were significantly higher than that in control group(P
