With the rapid development of therapeutic colon-technology,we see the daylight of its clinic use.But, at the same time,there are many social,ethical problems.We think, cloning human embryo and extracting stem-cells should be protected ethically. The fusion of the cells of human and rabbits violates the principles of life such as dignity.harmony and independence.Cloning organs of animals and transplanting them to patients can not shun the social and ethical problems and those of the law. So, the first and most important thing is to formulate the norm of the law and that of the athics.

Objective To investigate the correlation of diabetic skeletal muscle disease with macroangiopathy, and to explore the related genes of Shenqi Compound Recipe (SCR) in preventing and treating diabetic skeletal muscle disease by using gene chip technique, thus to reveal the molecular mechanism. Methods KKAy mice were fed with water containing nitri oxide synthase inhibitor of Nω-nitro-L-arginine methyl ester ( L-NAME) and high fat diet to induce the macroangiopathy complicated with type 2 diabetes. The experimental animals were divided into normal c57BL/GJ group, KKAy group, model group, SCR group (in the dosage of 14.4 g·kg-1·d-1) and rosiglitazone group ( in the dosage of 1.33 mg·kg-1·d-1) , 15 in each group. The medication groups were administered the corresponding agents for 8 consecutive weeks just as the modeling began. During the experiment period, blood glucose was monitored. At the end of the experiment, the abdominal aorta and skeletal muscle of mice were taken out for the observation of morphological changes, and differentially expressed genes of skeletal muscle between SCR group and model group, and between model group and KKAy group were detected by gene chip technique. Results SCR had an effect on relieving the atrophy, edema, fracture, and inflammatory changes in the skeletal muscle. There were 198 genes differentially expressed between model group and KKAy group, including 119 up-regulated genes and 79 down-regulated genes. There were 70 genes differentially expressed between SCR group and model group, including 33 up-regulated genes and 37 down-regulated genes. In the two comparison groups, 7 genes ( Celsr2, Rilpl1, Dlx6as, 2010004M13Rik, Anapc13, Gm6097, Ddx39b) showed reversed differential expression. Conclusion Diabetic skeletal muscle disease is associated with macroangiopathy. SCR has preventive effect on diabetic skeletal muscle lesion, and the mechanism may be related to the regulation of Celsr2, Rilpl1, Dlx6as, 2010004M13Rik, Anapc13, Gm6097, Ddx39b gene expression.

Objective To evaluate the surgical treatment of old patients with acute perforated gastroduodenal ulcer. Method The age, complications, duration of the disease history, operative method, systemic inflammatory response syndrome (SISR) and multiple organ dysfunction syndrome (MODS) in 89 old patients with acute perforated gastroduodenal ulcers were analyzed retrospectively. Results Simple closure operation was performed in 78 cases and subtotal gastrectomy in the other 11 cases. Twelve patients died. The mortality and complications rate were significantly lower in the patients less than 70 -year old than those in the patients more than 70-year old (P

This paper is to survey two groups of medicine-oriented English major undergraduates who have their probation either before or after the Quality Monitoring System is introduced to them about their degrees of learning satisfaction through questionnaires and seminar discussions. As a result, it proves that the implementation of the Quality Monitoring System in student probation helps to raise the degrees of student learning satisfaction, which clearly promotes the probation quality and secures the fulfillment of the mission in practice.

Taxol could induce tumor cell apoptosis throug h activation of Fas/FasL and caspases. bcl-2 also played an important role in t axol-induced cell apoptosis. Furthermore, taxol had the similar action with lip opolysaccharide on inducing the release of bioactive substances including tumor necrosis factor, interleukin and nitric oxide. There were as well some progresse s in taxol-resistance of tumor cells.

Objectives:To explore the influence of nutritional support treatment on patients with the injured pancreatitis. Methods:The twenty five cases with injured pancreatitis were divided into research group (13 cases of 1997-2001, with nutrition support) and control group (12 cases of 1992-1996,without nutritional support). Blood composition, biochemistry, complications, hospitalization time and mortality were compared between two groups. Results:WBC, amylase, glucose, transaminase and BUN were beginning to decrease in two days, and reached to normal limits in 6～7 days in research group. Lymphocyte count after treatment in research group was significantly different ( P

Objective The aim of our study is to establish and characterize the animal model for au- toimmune myositis.Methods Fifty male SD rats were randomly divided into 2 groups:model group(n=40) and control group(n=10).The model group rats were immunized with muscle homogenate every week for 5 weeks and received an injection of 2?g pertussis toxin at the first and second week.As controls,10 SD rats were injected with an equal volume of normal saline.Tissue specimens from limb skeletal muscles were ob- tained at 1,2,3,4,5 weeks after injection.At the same time,the blood samples were collected,and the level of CPK was measured.Results The model group had significantly elevated serum CPK levels.There were multiple inflammatory lesions in the skeletal muscles.Local degeneration and necrosis of muscle fibers with disappeared transverse striation,mononuelear cell infiltration in the interstitial could be observed.The patho- logic grade was mainly 2a.The infiltrating mononuclear cells were predominantly CD8~+T cells that mainly lo- cated in the endnmysium.MHC classⅠantigen expression on muscle fiber membranes in the model group was upregulated.Conclusion The experimental autoimmune myositis induced by syngeneic skeletal muscle ho- mogenate in SD rat is pathologically similar to human myositis.It can be used as a good model for human myositis and provides the basis for the etiopathology and therapeutical studies.

OBJECTIVETo observe the effects of Xiaobai Decoction (XBD) in reducing albuminuria and shortening the duration of albuminuria in patients with pregnancy-induced hypertension syndrome (PIH) in puerperium.

METHODSEighty-five patients were given the conventional treatment with magnesium sulfate for relieving convulsion and lowering hypertension, at the same time, the treated group was given XBD additionally with the modification according to the symptoms. The treatment course for both groups was 14 days. Routine test of midstream urine was performed every three days, and 24 h-urinary protein was measured every week.

RESULTSThe therapeutic effect on the 43 patients of the treated group was markedly effective in 11 (25.6 % ), effective in 26 (60.4%) and ineffective in 6 cases (14.0%), the total effective rate being 86.0%; while in the 42 patients of the control group, the corresponding numbers were 5 (11.9%), 21 (50.0%), 16 (38.1%) and 61.9%, respectively, the efficacy of the former was significantly better (P < 0.05).

CONCLUSIONXBD is a simple, safe and effective drug for reducing albuminuria and shortening the duration of albuminuria in puerperium of PIH patients.
