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 study the effects of phase change material (cooling agent) on the quality of blood after long-distant transportation.Methods A total of 12 bags, packed with pre-chilled phase change materials, were put into regular blood transportation kit, and the new blood transportation kit, which was developed by our hospital. In each kit there were 54 U of red blood cell suspensions. The temperatures in the kit were recorded during the transportation at different times.Results The temperature in the kit was kept between 1—7℃ during the 72h transportation. The temperature met the needs of red blood cell transportation.Conclusion Phase change material could be used as an effective cooling agent for long distance blood transportation.

[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.

Granulocyte macrophage-colony stimulating factor (GM-CSF) is a muhifunctional growth factor. It stimulates the proliferation, differemiation and maturity of hematopoietic progenitor cell (HPC), and transfers from bone marrow to periphery, inducing multiple cell proliferation or differentiation. In recent years, some studies have indicated that GM-CSF plays an important role in anti-apoptosis, inducing neuronal differentiation and angiogenesis, which will he a new supplement to the treatment of ischemic cerebrovascular disease. This article reviews the effects of GM-CSF in the treatment of ischemic cerebrovascular disease.

Objective To investigate the relationship between wound suture and incision complications in acute gastrointesti -nal tract incision .Methods Patients with abdominal surgery ( acute digestive tract perforation , and acute intestinal obstruction ) were divided into two groups .The differences between two suture methods were compared with the indicators such as operative time , incision complications, and hospital stay, etc.Results There were no significant differences between two groups (12.5%vs 20%) in incision complications ( P >0.05 );while there were differences in the postoperative hospital stay between two groups .The hospital stay of the intradermalsubcutaneoussuturegroup(13.54±7.32)dweresignificantlyshorterthanthatoftraditionalgroup(18.11±11.67)d(P<0.05 ) .Conclusions Wound intradermal subcutaneous suture was superior to traditional suture in acute gastrointestinal tract inci -sion.No significant difference was found between two groups in incision complications , but wound intradermal subcutaneous suture had significantly shorter postoperative hospital stay .

Objective: To discuss how to improve the level of diagnosis and treatment about the firstbranchial fistula. Method:16 cases with the first branchial fistula were analyzed retrospectively. Result :Of all thepatients underwent surgery, 14 cases were free from disease postoperatively within 0.5 years follow-up, 2patients underwent re-operation because of recurrence. Conclusion:Knowing about the disease fully, selectingproper surgical incision and possessing skilled surgical technique is important to improve the level of diagnosisand treatment about the first branchial fistula.

Objective] Observing Cortex Lycii Radicis' effect(Cortex Lycii) on rat insulinoma cells(INS-1) proliferation and apoptosis. To explore the mechanism of Cortex Lycii on Pancreatic Beta Cell Proliferation and apoptosis.[ Methods] After primary culture, cells were randomly divided into blank control group:control,11.1mmol·L-1 glucose,HG,30mmol·L-1 glucose, HG+Cortex Lycii(1g·L-1), HG+Cortex Lycii(2g·L-1), HG+Cortex Lycii(4g·L-1), the survival rate of cells was observed by cell counting kit-8(CCK-8);the apoptosis rate was observed by Annexin V stammg. [Results] ①Compared with HG the better effect of cell proliferation groups of Cortex Lycii(P<0.01), the best is group of Cortex Lycii(2g·L-1)(P<0.05) ②Compared with HG group the higher survival rate is group of Cortex Lycii(P<0.01), the lower apoptosis rate of Cortex Lycii(2g·L-1) compared with Cortex Lycii(1g·L-1). [Conclusion] Cortex Lycii can promote the proliferation of pancreatic beta cell, inhibit the apoptosis to protect the pancreatic beta cell. The optimal concentration is 2g·L-1.

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.
