The basic research and development of xeno-transplantation technique has been a new field. The article analyzed its current situation and problems, discussed the ethical problems the researchers and physicians faced, and raised a series of ethical principles which should be obeyed in xeno-transplantation, that is: stick to combining humanism and utilitarianism; observe the technological and sanitary criterion, choose the graft cautiously; Be attentive and loyal to the recipient's health; no harm and beneficial to the humankind. Besides, the article explored the importance of setting up laws and regulations about xeno-transplantation.

Objective To study and compare the effects of different surgical operation in treatment of adolescent idiopathic seoliosis. Methods 70 patients with adolescent idiopathic seoliosis and patients informed consent were selected as research object,and they were divided into group A 35 cases and group B 35 cases according to their willingness, and they were separately treated with videoassisted anterior thoracoscopic correction and traditional anterior thoracoscopic correction, then the surgical time, complications, hospital stays, rates of patients satisfaction, total effective rate and Cobb, before and after the treatment were detected and compared. Results The surgical time [(225.6 ± 30. 8) min] and hospital stays [(2. 7 ± 0. 8) d] of group A were all shorter than those of group B [( 365. 4 ±23. 8) min, (4. 8 ± 1.2 ) d] ( t = 3.26,3.78, all P ＜ 0. 05 ), complications rate ( 8. 6% ) was lower than that of group B (20. 0% ) ( x2 = 3. 45, P ＜ 0. 05 ), rates of patients satisfaction ( 97. 1% ) and total effective ( 97. 1% ) were higher than those of group B(80. 0% ,85.75% ) (x2 =2. 85,3.01 ,all P ＜0.05) ,Cobb( 14. 2 ± 5.4)°was smaller than that of group B(23. 4 ±5.6) °(t =2. 97 ,P ＜ 0. 05). Conclusion The effect of vidcoassisted anterior thoracoscopic correction in treatment of adolescent idiopathic seoliosis was good,and complications rate was low and it was worthy of extend and application.

Objective To explore the effective treatment in children of abdominal allergicpurpura.Methods To retrospectively analyze the clinical data of 54 children with abdominal allergicpurpura.54 cases were divided into three groups.Each 18 cases in group Ⅰ,groupⅡ,and group Ⅲ.It was used large doses of methylprednisolone in the group Ⅰ,ranitidine in the groupⅡ,and cimetidine in the groupⅢ,based on conventional treatment.To analyze the effect and adverse effect after the treatment.Results The effect of groupⅠ,and groupⅡ,was significantly higher than group Ⅲ(t=11.775,8.901,7.613,5.786,10.105,12.347,all P＜0.05).There was no significant difference between groupⅠ,and group Ⅱ(P＞0.05).The adverse effect of groupⅠ,was significantly higher than the other groups(x2=4.500,5.017,all P＜0.05).Conclusion The treatment of hormone had obvious effect in children with abdominal allergicpurpura,but it had some risks in the gastrointestinal,so we should close observe the gastrointestinal tract in children.Ranitidine and cimetidine are the drugs of inhibiting gastric acid secretion,but the ranitidine much better than cimetidine.

Immunological imbalance is the foundation for the development of liver damage or fibrosis.Therefore,the treatment of liver disea-ses not only relies on regenerative medicine for cellular replacement,but also depends on immunoregulation.The immunological basis of liver injury and repair,the immunological basis of multipotent stem cells for allograft,and the research advances in the immunoregulatory effect of stem cells in the treatment of liver diseases demonstrated that multipotent stem cells,especially mesenchymal stem cells,have low immuno-genicity and cause immunosuppression,with the immunological basis of allograft;in addition,they can improve the local immune microenvi-ronment of the liver by immunoregulation to reduce the liver injury caused by immune response.It is suggested that multipotent stem cells, which meet the requirements of cellular replacement and immunoregulation in the liver,will become an ideal treatment of liver diseases.

Because of insufficient intake,synthesis disorder,metabolic disorder and excessive consumption,patients with cirrhosis often lead to malnutrition. Providing scientific nutritional support and guiding the patients to a reasonable diet can effectively improve the liver metabolism and reduce the complication of cirrhosis such as hepatic encephalopathy,and improve the quality of life and survival rate. This article described the nutritional metabolism disorder in patients with cirrhosis and nutritional treatment in hepatic encephalopathy.

Physical factor therapy is commonly used in the treatment of nervous system damage. Recent years, physical factor therapy gets popular attention because of its good therapeutic effects, low cost, simple operation and widely application. This article respectively in-troduced the effects of electrical stimulation therapy, functional magnetic stimulation therapy and biofeedback therapy on neurogenic blad-der.

Objective To explore the short-term and long-term clinical effect of leep knife treatment of chronic cervicitis. Methods A single-center, prospective, randomized, controlled study was used, 120 patients with chronic cervicitis were randomly divided into observation group and control group, each group of 60 patients. Patients in the observation group were treated with (LEEP) knife, parameters setting frequency was 3.8 MHz, power was 30 ~ 40W, patients in the control group were treated with microwave. The intraoperative and postoperative recovery and relapse were compared between two groups. Results The intraoperative blood loss, operative time, postoperative vaginal discharge time in the observation group were significantly less than control group, there was a significantly statistical difference (P<0.001) . After two weeks and three months , the cure rate in observation group were 70% and 98.33% respectively, the cure rate in control group were 16.67% and 51.67%, there was a significantly statistical difference (P <0.01) . After 2 weeks and 3 months, the infection rate and recurrence rate in the observation group were significantly lower than the control group, there was a significantly statistical difference (P <0.05) . Conclusion Leep knife for treatment of chronic cervicitis patients has lower postoperative recurrence, lower infection rate and higher cure rate in short-term and long-term, and less intraoperative trauma, shorter operation time, and has important clinical significance for the prognosis of patients.

Objective To observe changes on those parameters on pletelet and hemoglobin of urinaemia patients by treatments of dialysis.Methods candidators are divided into three groups respectively-a control group,two case groups.The two case groups are consist of patients who are treated through dialysis on not.In the three groups,the parameters on pletelet,hemoglobin,MPV and PDW are measured on hemocytometer in our laboratory. Results Dramatic difference is made in the parameters on PLT,Hb,MPV and PDW between the formers of dialysis and the control group.(P

So as to explore the relationship between hypertension happen and combined phlegm and blood stasis,aswell as relations to fi ve zang-viscera,we analysis and study the related articles in literatures of past dynasties about phlegm,blood stasis with dizzy and headache,fi ve zang-viscera with dizzy and headache.We fi nd that there are relationships between phlegm and dizzy and headache,between blood stasis and dizzy and headache,between fi ve zang-viscera and dizzy and headache,as well as between phlegm,blood stasis and disorders of functions of fi ve zang-viscera.Thus,phlegm induces dizzy and headache,blood stasis induces dizzy and headache,the disorders of functions of fi ve zang-viscera cause phlegm or blood stasis,and the diseases of fi ve zang-viscera induce dizzy and headache.Therefore,the happen of dizzy and headache in hypertensive disease has direct or indirect relationships with diseases of fi ve zang-viscera,which should be noticed in clinical treatment.In clinical practices,we fi nd that in the f ive zang-viscera,the heart and kidney have the close relationship with hypertension.In literatures of past dynasties,the discuss about combined phlegm and blood stasis inducing diseases can be found,but there are no records about combined phlegm and blood stasis inducing dizzy and headache,though that is one of the most important pathological factors of hypertension happen in clinical treatment,so we should pay attention to combined phlegm and blood stasis in the treatment of hypertensive disease.
