Objective To observe the effects of hepatocyte-like cells differentiated from human umbilical cord mesenchymal stem cells (HuMSCs) on the liver function of the rats with liver cirrhosis.Methods Carbon tetrachloride was used to prepare rat model of liver cirrhosis.Then the rats in the experimental group received portal vein injection of 1 ml differentiated hepatocyte-like cells (1 × 107) ; the mesenchymal stem cell (MSC) group was injected with the same volume and number of MSCs; the model group was injected with the same volume of saline (NS) ; the normal rats were treated as control group.After transplantation,the rat angular vein blood and liver tissue were obtained for testing.Results One week after transplantation,compared with the model group,levels of serum alanine aminotransferase (ALT),aspartate aminotransferase (AST) and total bilirubin (TBil) in the experimental group significantly decreased (P ＜0.05),while the albumin (Alb) level increased significantly (P ＜0.05).Compared with the MSC group,the level of Alb in the experimental group also significantly increased (P ＜ 0.05),but there were no differences between the two groups of ALT,AST and TBil.4 weeks after transplantation,compared with the model group,levels of serum ALT,AST and TBil in the experimental group also significantly decreased (P ＜ 0.05),while Alb level increased significantly (P ＜ 0.05).Compared with the MSC group,the differences of the levels of Alb,ALT,AST and TBil were all statistically significant (P ＜ 0.05).Real-time PCR test results showed that the expressions of four liver-related genes of the MSC group and experimental group significantly increased comparing with the model group (P ＜ 0.05).And the experimental group showed higher expression level comparing with the MSC group (P ＜ 0.05).Conclusion The differentiated hepatocyte-like cells could improve hepatic function of patients with liver cirrhosis to a certain degree and showed greater advantage than MSC.

ObjectiveTo investigate the high risk factors,etiology,diagnosis,treatment and precaution of venous thromboembolism (VTE) in pregnancy and puerperium. MethodsData of 16 cases of VTE admitted in Department of Obstetrics and Gynecology,Peking Union Medical College Hospital from January 1992 to April 2011 were analyzed retrospectively.The differences of blood routine test and coagulation function between VTE patients (study group) and normal pregnant women (control group) were compared by paired t test in this case-control study.Results All patients were diagnosed by color Doppler ultrasound or CT pulmonary artery angiography.Five cases (31.2 ％) occurred before delivery and 11 (68.8 ％) occurred during postpartum.Two cases (12.5 ％)complicated by pulmonary thromboembolism,and one of them died.Six cases (37.5％) were older than or equal to 35 years old,and 12 cases (75.0％) had gestational complications.The hematocrit in study group were lower than that in control group (0.29±0.06 vs 0.39±0.02,t=4.56,P=0.01).There was no statistical difference between the coagulation function of the two groups.After anticoagulant therapy or surgery,15 cases recovered.One pulmonary thromboembolism patients complicated with rheumatic cardiac disease remained shock after anti-coagulants was administered,then died of hemorrhage of respiratory tract after inferior vena cava filter placement. Conclusions VTE is likcly to happen in puerperium than in pregnancy.There are no good screening indicators for thromboembolism during pregnancy and puerperium.Anticoagulation is recommended to be the first line therapy.For women with high risk of thromboembolism,it is suggested to prevent actively and treat early to decrease the complications and long-term sequelea.

Objective:To make a preliminary application of the assessment system for cancer pain management and find insuffi-ciency in the clinical practice of cancer pain diagnosis and treatment. Methods:Data from 41 doctor questionnaires, 43 nurse question-naires, 50 patient questionnaires, and 12 ward questionnaires from the tumor departments of 3 hospitals were analyzed, and the insuffi-ciency in cancer pain management was determined. The wards in the tumor and non-tumor departments related to oncology were as-sessed using rank test, and differences between the 2 wards were investigated. Results:The average scores of doctor, nurse, and wards were 85.41±5.93, 88.46±5.09 and 83.75±3.11, respectively, whereas patient score was 68.67±7.14. To further analyze the patient subsys-tem by converting into a hundred-mark system, the effectiveness and safety scores for the pain management was 81.69±7.71. However, patients' opinion score on pain treatment was only 55.78±11.37. The score of tumor departments was 82.22±2.03, whereas related non-tumor departments had a score of 39.27 ± 3.58. Wilcoxon W value was at 120.0 with P<0.01 after rank test. Conclusion:Education on patients' opinion on cancer pain management should be promoted in the tumor wards, and continuous education on cancer pain diagno-sis and treatment is needed in the non-tumor departments relative to oncology.
