Objective To explore the influence of cirrhotic portal hypertension and its complications on liver transplantation. Methods The literatures of the recent years on influence of hepatic cirrhotic portal hypertension on liver transplantation were reviewed. Results Splenomegaly, hypersplenism, portal vein thrombosis, portosystemic shunt and collateral flow in cirrhotic patients will increase the difficulty of liver transplantation and lead to more postoperative complications. Appropriate handling of these conditions can achieve a higher success rate of liver transplantation. Conclusion Correct management of end-stage cirrhotic portal hypertension and its complications can expand the indications of liver transplantation and improve long-term survival rates.

[Objective]To understand the changes of children's blood lead levels and intelligence quotient (IQ) andthe effects of automobile exhaust on the prevelance rates of respiratory symptoms of children. [Methods] 151 pupilsof Y primary school in urban area were selected as exposure group, 160 pupils of Z primary school in Pudong districtwere selected as control group. The health questionaire survey and health examination were carried out amongpupils. The peripheral blood lead levels of the forth finger were determined. The IQ was determined by combinedRaven's Test. The data were statistically analzed by EPI Info and SAS statistic softwares. [Results] Significant differ-ences of blood lead levels were observed between exposure group and control group. The blood lead levels (x) negatively correlated with children's IQ (y) (y= 120. 11--0. 129x) . The prevelance rates of sore and uncomfortable feelings and foreign body sensation in throat and cough of exposure group were significantly higher than those in controlgroup. The ORs of corresponding symptoms were 1.71, 2, 64 and 2. 92 respectively. The multiple linear regressionanalysis showed that exposure to automobile exhaust and the distances from the residential region to street with heavytraffic were the main factors affecting the children's peripheral blood lead levels and the prevelance of respiratorysymptoms. [Conclusion] Further control of the emission of automobile exhaust and reasonable planning of location ofresidential areas were the main measures to control the prevelance of lead poisoning and its related diseases of children.

Because of the characteristics of microRNAs (miRNAs) and their important regulative roles in human tumor diseases,they may be novel approaches for gene target therapy.Most studies focus on finding critical regulator miRNAs of oncogenes or tumor suppressor genes.Recent researches show that the expression of miR-221 and miR-222 are abnormal,and they play different roles in different types of human tumors.The regulation of miR-221 and miR-222 may be a novel effective therapy for tumor.

Objective: To investigate the relationship between human papilloma virus (HPV) gene types and cervical diseases. Methods:The subjects included women with HPV who were diagnosed in the Outpatient Department of the Third Affiliated Hospital of Sun Yat-sen University (Guangzhou, China) from March 1, 2010 to January 31, 2011. A total of 21 HPV DNA types were found in the women using DNA flow-though hybridization genotyping technique, and a questionnaire-type survey was conducted on these pa-tients. In this study, 256 cases of normal or inflamed cervix, 34 cases of cervical intraepithelial neoplasia I (CINⅠ), 61 cases of CINⅡor CINⅢ, and 9 cases of cervical cancer were analyzed. Results:The HPV infection rates were 18.4%in the normal cervical or inflam-mation group, 67.6%in the CINⅠgroup, 96.7%in the CINⅡor CINⅢgroup, and 100%in the cervical cancer group. The HPV in-fection rate was higher in the CIN I group than in the normal HPV infection or inflammation group (P<0.001) and was higher in the CIN Ⅱ or CIN Ⅲ groups than in the CIN I group (P<0.001). The main types of infection were HPV16 (44.2%), HPV58 (24.2%), HPV52 (11.6%), and HPV33 (8.4%) in the CIN groups. The main type of infection was HPV16 in the cervical cancer group (88.9%). Conclusion: Cases of cervical lesions are increasing. With this prevalence of HPV, considerable attention should be focused on HPV16-, 58-, 52-, and 33-related infections and cervical lesions. Among them, HPV16 infection is the primary cause of disease progres-sion and carcinogenesis.

OBJECTIVE:To outline the development of phytomedicine in Germany to offer a reference for traditional Chinese medicine.METHODS:From the aspects of research,production and market to make an exposition of phytomedicine's develop?ment in Germany.RESULTS:There existed a gap between Germany and China in technology and standards in production of botanicals.CONCLUSION:We should use the experience of Germany in developing botanicals to draw up international quality standard of traditional Chinese medicine.

Objective To establish an effective method for inducing mouse bone marrow mononuclear cells(MNCs) to differentiate into hepatocytes.Methods MNCs were isolated by gradient density centrifugation,and the cells were cultured in Iscove's Modified Dulbecco's medium supplemented with 10 % new bovine serum(NBS),20 ng/ml hepatocyte growth factor(HGF),10 ng/ml fibroblast growth factor-4(FGF-4) and 10 ng/ml oncostatin m(OSM) for 21 days' induction.The medium was changed every 3 days.Results When MNCs were cultured with HGF,FGF-4 and OSM,cuboidal morphology was observed,and cells also expressed marker genes specific for liver cells in a time-dependent manner.?-fetoprotein(AFP) and cytokeratin 19(CK19) were expressed on the day 7,and CK18 and TAT were detected on the day 14-21,in common with the immunofluoresence results.Differentiated cells further demonstrated these cells also acquired functional characteristics of hepatocytes.Conclusion Mouse MNCs can differentiate into hepatocytes when induced by HGF,FGF-4 and OSM.

Objective To study the mithridatism of VMAT 2 in transgeneic CHO cell.Methods Using technology of transgene from PC 12 to CHO, MTT reduction assay was used to detect the toxic effect on MPP + to wtCHO and cDNACHO,meanwhile the role of reserpine was observed,including the toxic effect to MPP + on specific blocking agent of VMAT 2.Results cDNACHO to the sensitivity of MPP + was much less than that of wtCHO over concentration of 0.5 mmol/L MPP +; cDNACHO had the same sensitive as wtCHO to rotenon;after the reserpine was added,the above role disappeared,but wtCHO reserpine was given alone,it couldn't change its sensitivity to MPP +.Conclusion VMAT 2 has protective effect on cDNACHO by transporting MPP + to vesicles; PC 12 possesses the antitoxic components.
