BACKGROUND:Research on liver transplantation has not just focused on survival rate and survival time, and the quality of life has become a new field of study. However, it is stil a blank about the quality of life of liver transplant recipients in Xinjiang. OBJECTIVE:To investigate the quality of life of liver transplant recipients in Xinjiang and to explore the main risk factors for the quality of life in patients. METHODS: A Chinese version of the SF-36 health survey was used to retrospectively evaluate the quality of life of liver transplant recipients in Xinjiang. RESULTS AND CONCLUSION:The scores of al eight dimensions in the patients with liver transplantation ranged from 60.6±18.7 to 93.9±22.1. Primary diseases, operation method, marital status, level of education, occupation, gender and age could influence the quality of life of the liver transplant recipients, but nation, income and the way of medical insurance had no significant effect on the quality of life. These findings indicate that there is no obvious difference in the quality of life between liver transplant recipients and normal population, and the scores in six dimensions are higher in the liver transplant recipients than normal population, which is further confirmed that liver transplantation is an effective way for treatment of advanced liver disease.

Objective To explore the effects of improved preparation before urodynamic examination in the elderly patients with voiding disfunction.Methods Totally 424 elderly patients underwent urodynamic examination after improvement of the preparation approach according to pathophysiological characteritics of the elderly patients,and 248 elderly patients before the approach improved in our center were collected as control.The compliance,discontinuation and repetition rate of urodynamic examination were compared between the two groups.Results The compliance of patients who used the improved preparation approach was significantly higher than control (92.5% vs.59.3%,x2=106.428,P<0.001).Whereas the discontinuation and repetition rates of urodynamic examination in the improved group were decreased as compared with control group ( 1.2% vs.6.9%,x2 =14.176,P=0.0002; 8.5% vs.21.4%,x2 =21.487,P<0.001).Conclusions The improved preparation approach according to the pathophysiological characteritics of elderly patients is worthy to popularize in the urodynamic centers.

According to the existing Provisions for Drug Registration (SFDA Order No. 28), applications for new drugs of traditional Chinese medicine are divided into two parts: the applications for drug clinical trial and for drug production (including new drug certificate). It will last for about 10 years from the application for drug clinical trial to get approving, and it also remains many problems and the low probability to succeed. From the sight of pharmaceutical review, there are mainly two aspects of regulatory compliance and technical issues, mainly for changes without approval of the competent authorities of the country. For example, sample preparation and approval of clinical trial process are significant changes. Technical problems are reporting incomplete data or information submitted does not comply with the technical requirements for review, such as: production process validation does not provide information, the preparation of samples for clinical trials and field inspection, production information, or the information provided does not meet the technical requirements. This paper summarizes the frequently asked questions and to make recommendations to advise applicants concerned, timely detection of problems, avoid risk, improving the quality and efficiency of the application for registration.

BACKGROUND:Airway epithelial regeneration can effectively inhibit submucosal hyperblastosis and the occurrence of obliteration. Studies demonstrated that ventilation could accelerate the regeneration of airway epithelium. OBJECTIVE:To establish and improve an orthotopic tracheal transplantation model and to further observe the effects of ventilation on trachea in alogeneic mice. METHODS:C57BL/6 mouse's tracheal served as donor, and BALB/c mouse's tracheal as recipient. This experiment contained two groups. In the experimental group, the membranous part of trachea was longitudinaly dissected in two donors and sutured into an enlarged trachea, which was implanted in the recipient. In the control group, donor's trachea was implanted into the recipient in situ. Samples were obtained and detected at 28 days after surgery. RESULTS AND CONCLUSION: Hematoxylin-eosin staining results demonstrated that compared with the control group, wel-differentiated ciliated epithelium was visible in the epithelial lamina of tracheal lumen, accompanying a few non-ciliated single or stratified squamous epithelium, mild submucosal fibrosis and inflammatory cel infiltration. Morphological analysis revealed that ciliated epithelial proportion in the experimental group was higher than in the control group (P < 0.05). The ratio of lamina propria to the tracheal cartilage, submucous fibrous tissuearea and the degree of lymphocyte infiltration were lower in the experimental group than in the control group (P < 0.05). Immunohistochemical staining demonstrated that the transplanted tracheal epithelium in both groups was recipient epithelial phenotype. Results verified that a modified orthotopic tracheal transplantation model was successfuly established. The increased ventilation of the tracheal alografts can accelerate the differentiation of tracheal epithelium. The wel-differentiated airway epithelium inhibited the proliferation of fibroblast.

Objective To investigate the factors impact on the mortality of severe acute pancreati- tis(SAP)and the related treatment methods.Methods The data from 24 patients died of SAP from Jan- uary 1993 to June 2006 were retrospectively analyzed.The factor that impact motality and treatment measures were also analyzed.Results The mortality of patients with SAP was 6.65%(24/361).Multi- ple organ dysfunction sydrome(MODS)was the main cause of death in early stage of SAP.The infection was an important cause in later stage.The mortality was higher in SAP patients with other complications than those without.Conclusions MODS is the main cause of death in early stage.Close monitoring and supportive treatments in early stage can reduce mortality.Individualized treatments,including nonsurgi- cal,surgical and interventional therapy should be adopted in later stage,with emphases on reducing com- plications.

The aim of this study was to investigate the effect of Bu-Shen-An-Tai recipe (BSATR) and its two components (Bushen recipe, and Huoxue recipe) on endometrial morphology during peri-implantation in superovulated mice. Mice were randomly divided into five groups, including the normal (N), model (M), Bushen (BS), Huoxue (HX) and Bu-Shen-An-Tai (BH) groups. The uteri were collected on day 4 of pregnancy, and the endometrium thickness, microvessel density (MVD) and number of pinopodes observed. Compared with the M group, the endometrial thickness in the BS, HX and BH groups was significantly increased and there was a significant difference in endometrial thickness between the BS and the BH groups. The mean MVD was significantly lower in the M group than in the N group, and there was a significant increase in MVD in the BS, HX and BH groups as compared with the M group. Compared with the M group, the pinopode scores in the endometrium were significantly increased in the HX and BH groups; and the BS group had significantly higher pinipode scores than the HX and BH groups. In conclusion, the results of the present study demonstrated that the recipes (Bushen, Huoxue and BSATR) could improve the endometrial environment by regulating the endometrial thickness, MVD and the number of pinopodes at the window of implantation. Moreover, the Huoxue recipe and the BSATR were more efficient than the Bushen recipe, with the BSATR tending to have the most beneficial effects.
