1. Expression of Bcl-2 and Bax protein in contusive brain tissue in patients of different ages
Academic Journal of Second Military Medical University 2010;28(10):1113-1115
Objective: To study the influence of different ages on expression of Bcl-2 and Bax protein in the contusive brain tissues after traumatic brain injury (TBI), so as to probe into the molecular mechanism of the age influence on the prognosis of TBI patients. Methods: The expression of Bcl-2 and Bax protein in contusive and lacerated brain tissue (within 3 h to 9 h after trauma) in aged group (≥ 60 years), adult group (19-59 years) and non-adult group (≤18 years) was analyzed and compared by immunohistochemistry method and computer micrograph analysis. The temporal lobe samples of 15 patients with temporal epilepsy or vascular deformity were taken as control. Results: The expression of NGF, Bcl-2 and Bax protein in the contusive and lacerated brain tissue was higher in the 3 TBI groups than that in the control group. The ratio of Bcl-2/Bax expression in aged group was significantly lower than those in the adult and non-adult groups (P <0.05); and the ratio of Bcl-2/Bax expression in the adult group was significantly lower than that in the non-adult group (P<0.05). Conclusion: The expression of Bcl-2 and Bax protein after TBI is influenced by the age of sufferers; the decrease of Bcl-2/Bax ratio might be associated with the neurological deficits after TBI in aged patients and the higher ratio of Bcl-2/Bax might be associated with the better prognosis of TBI in non-adult patients.

Objective To study the value of transcatheter arterial chemoembolization (TACE)in combination with portal vein chemotherapy (PVC) after resection of hepatocellular carcinoma to prolong survival. Methods From January 2000 to July 2007, 168 patients with hepatocellular carcinoma (HCC) underwent tumor resection in our hospital. After operation, TACE in combination with PVC was performed in 48 patients (combined group), TACE alone in 26 (TACE group), PVC alone in 50 (PVC group) and none of the above in 44 (control group). All the patients were followed up for 17-96 months. The 1-, 3-and 5-year survival rates were compared among the 4 groups. Results Accumulative 1-, 3-and 5-year survival rates were higher in the combined and TACE groups than in PVC and control groups. Conclusion After resection of HCC, combined use of TACE and PVC is the same as TACE in prolonging patient survival. However, it is better than PVC alone and non-surgical procedure.

Objective To investigate the mechanism of the inhibitory effect of ?-ray irradiation on rat vascular smooth muscle cells(VSMC). Methods The ef fect of ?-ray irradiation on proliferation of VSMC was observed by 3?H-TdR incor poration. After ?-ray irradiation, the VSMC cell cycle change was detected b y flo w cytometry. The expression of p53, cyclin D and PCNA was investigated by Wester n Blot. Results The inhibitory effect of ?-ray irradiation on VSMC proliferati on was dose-dependent. After ?-ray irradiation, VSMC was arrested in G 1 st age, w ith the expression of p53 increased but the expression of cyclin D and PCNA decr eased. Conclusions ?-ray irradiation can inhibit the proliferation of VSMC. T he main mechanism is probably due to the induction of cell cycle arrest and inhi bition of the VSMC mitosis ,during which process, p53,cyclin D and PCNA all pla y an important role .
