CD44+ CD29+ and CD44- CD29+ bone marrow mesenchymal stem cells (BMSCs) were isolated from bone marrow of BALB/C male donor mouse by adherence selecting in DMEM media with low glucose and 20% fetal bovine serum. Then P5 cells were injected into the liver remnants of hepatectomined female mouse. Simultaneous assays were performed on the injected liver lobe and other liver lobe for detecting the Y-chromosome by fluorescence in situ hybridization and for defecting the albumin or cytokeratin 18 (CK18) by fluorescence immunoassays. Both Y chromosome and albumin (or CK18) positive cell could be detected at 5 days and 14 days after transplantation. At 14 days after transplantation, the liver weight in transplanted mouse was higher than that in model mouse. These results suggest that BMSCs could be induced to differentiate into hepatocytes and participate in the regeneration of liver.

Objective To investigate the constitutive characteristics and the change trend of gynecologic malignant tumors in hospitalized patients in Guangxi Zhuang Autonomous Region over the recent 20 years.Methods Clinical data of 8009 in-patients who suffered from gynecologic malignant tumors in 23 hospitals from 1985 to 2004 in Guangxi Zhuang Autonomous Region were analyzed,with respect to the tumor types and change trend.Results(1)The leading 4 types of malignant tumors were cervical cancers, ovarian cancers,endometrial cancers,and malignant trophoblastic tumors according to the constitutive ratios of the tumors.The constitutive ratio of cervical cancer patients rose year by year,from 17.48% during the 1985-1989 period to 49.25% during the 2000-2004 period(P0.05).(2)The occurring age of cervical cancers became younger obviously,from≥60 years old dropped to
