Objective To assess the therapeutic outcomes of transcatheter arterial chemoembolization combined with percutaneous injection of chemoembolization agent intra-portal vein tumor thrombosis for primary hepatic carcinoma accompanied by portal vein tumor thrombus. Methods Thirty patients with primary hepatic carcinoma accompanied by portal vein tumor thrombosis of type Ⅱ and type Ⅲ were randomly divided into two groups. The Child-Pugh ratings (class A and B) of group A and B were 9 vs 9 (class A) and 5 vs 7 (class B) respectively (χ~2 = 0.201, P > 0.05). The constitution of Type Ⅱ and type Ⅲ portal vein tumor thrombus in group A and B were 8 vs 9 and 6 vs 7 respectively (χ~2 =0.002, P>0.05). The median values of ALT, TBIL, ALB and AFP in group A and B were 58.7U/L vs 70.5 U/L (W=191.5, P>0.05), 21.4 μmol/L vs 21.7μmol/L (W=203, P>0.05), 35.3 g/L vs 37.5 g/L (W = 214, P > 0.05) and 680 μg/L vs 873 μg/L (W = 179. 00, P > 0.05) respectively. Group A was treated with transcatheter arterial chemoembolization (TACE) using emulsion made up of adriamycin, cisplatin, mitomycin and ultraliquidlipiodol plus percutaneous injection of chemoembolization agent intra-portal vein tumor thrombosis using emulsion consisted of cisplatin and ultraliquidlipiadol, while group B was treated with TACE only as a control group. Survival analyses were performed via the Kaplan-Meier test in SPSS11.5 with the log-rank tests with an threshold of 0.05. Results The 3, 6 and 12 months survival cases of group A and B were 11 vs 10, 10 vs 3, and 7 vs 0 respectively. The median survival time of group A and group B were 14.0 months and 4.0 months respectively. The difference of the two groups was significantly (χ~2 =11.728, P<0.01). There was no severe side-effect related to therapy in both groups. Conclusion Comparing with the control group, TACE combined with percutaneous injection of chemoembolization agent intra-portal vein tumor thrombosis could significantly prolong the median survival time of patient with primary hepatic carcinoma accompanied by type Ⅱ and type Ⅲ portal vein tumor thrombosis.

Objective To study the effect of brain-derived neurotrophic factor (BDNF) on the environmental nutrition and neural differentiation of the transplanted stem cells under hypothermia.Methods The BDNF gene mediated by liposome was transfected into 293T cell line, and ELISA assay was applied to find the peak time of BDNF expression. When BDNF was highly expressed, the supernatant was collected for establishment of SD rat models of brain injury. The rats were divided into Group A (stem cell transplantation group) and Group B (stem cell transplantation and BDNF group). Rats in both groups were under hypothermia treatment for five days. Four and eight days later ( three days from rewarming), rat brain tissues were obtained to detect the expressions of proliferating cell nuclear antigen (PCNA), nestin, neuron-specific enolase (NSE) and glial fibrillary acidic protein (GFAP) by immunohistochemical method and to detect the apoptosis by in situ hybridization. Finally, the nerve function scores were obtained for evaluation of the nerve function. Results The ELISA showed that the high level of BDNF expression was at 48 to 60 hours after gene transfection. PCNA and nestin were highly expressed, while NES and GFAP showed nil or low level of expression in both groups at the fourth day after hypothermia, with little apoptotic cells especially in the Group B (P <0.05). The expressions of PCNA and nestin were decreased, but the expressions of NSE and GFAP were increased at the third day after rewarming. The positive rate of NSE expression in the Group B was much higher and the apoptotic cells were much less compared with the Group A ( P < 0. 05 ). A better nerve score was obtained in the Group B. Conclusion BDNF can enhance the survival rate of the transplanted stem cells and induce their differentiation into neurons under hypothermia.

BACKGROUND:In dynamic hip screw fixation for treating aged osteoporotic intertrochanteric fracture, avoiding the loss of bone mass, or by other means that can increase the fixed screw pulout strength, wil improve the therapeutic effect of dynamic hip screw fixation. OBJECTIVE: To compare the effects of three kinds of repair methods on aged osteoporotic intertrochanteric fracture. METHODS:Data of aged osteoporosis intertrochanteric fracture patients, who received conventional dynamic hip screw fixation, bone cement augmentation with dynamic hip screw fixation and bone grafting with dynamic hip screw fixation, were retrospectively analyzed. They were divided into control group, bone cement group and bone grafting group. RESULTS AND CONCLUSION:After two years of folow-up, the excelent and good rates of Harris hip function were 95%, 80% and 70% in the bone grafting, bone cement and control groups, respectively. The healing time of fractures was significantly shortened in the bone grafting group (P < 0.05). The failure of screw fixation was similar between the bone grafting and bone cement groups. Screw withdrawing appeared in the control group. Results suggest that compared with conventional dynamic hip screw fixation and bone cement augmentation with dynamic hip screw fixation, the therapeutic effect and safety of bone grafting in nail path with dynamic hip screw fixation were better.
