Objective To study the relationship between the microvessel damage and the death rate of tumor cells and determine role of microvessel damage in the tumoricidal effect of hyperthermia.Methods H22 hepatoma cells were inoculated in the right hind legs of KM mice with immunosuppression.Local hyperthermia was administered to these mice which were divided randomly into 10 groups (8 in each group),which included groups of 3,6,12,24,48,72 and 96 h after hyperthermia for 30 min and groups of hyperthermia for 15,30 and 45 min.The tumor tissues were analyzed by flow cytometry(FCM)and immunohistochemistry.The cultured H22 cells were also given hyperthermia for 15,30,45 min and analyzed by FCM.Results The apoptotic rate(0.115±0.008)was higher in the initiation phase of hyperthermia in vitro,then the necrotic rates rose gradually.The difference between in vivo and in vitro was significant in hyperthermia of the same time about death rate(P＜0.05).A strong positive linear correlation(r=0.844)was observed between the death rate of tumor cells and MVD.Conclusion Microvessel damage plays the cardinal role in tumoricidal effect of hyperthermia.

Chronic active Epstein - Barr virus infection(CAEBV) is an uncommon outcome of EBV infection and may present as severe of fulminant syndrome with high- mortality. It is characterized by chronic or recurrent infectious mononucleosis-like symptoms persisting over a long time and by an unusual pattern of anti-EBV antibodies. Although it occurs in immunocompetent individuals, a number of subtle immunologic defects have been reported in patients with CAEBV. Up to now, there are still no diagnostic criteria of CAEBV in China,so the author introduce it with respect to its diagnosis,history,pathogenesis and therapeutic approaches.

Objective To investigate the clinical role of a combination therapy of percutaneous radiofrequency ablation(RFA) and transcatheter arterial chemoembolization(TACE) in large hepatic tumors. Methods Out of 62 patients with hepatocellular carcinomas confirmed by pathology, 21 patients received a combination therapy of TACE and RFA(combination group), 22 patients TACE therapy alone, and the rest 19 patients RFA therapy alone. A total of 106 tumors with a mean diameter of ( 5.9? 0.7) cm(ranged from 5.0 to 8.1 cm) were detected, and the largest tumor was selected for observation in a patient with multiple lesions. There was no significant difference in mean age, tumor size and liver function grade among the three groups.Results Tumor complete necrosis accounted for 80.9%in combination group, which was significantly higher than that of TACE group and RFA group ( 27.2%, 47.4%,P 0.05). Mean survival duration of combination group was 25.6 months, significantly higher than that of TACE group( 14.9 months)(P0.05). Conclusions Compared with TACE or RFA therapy alone, the combination therapy improves tumor complete necrosis rate and prolongs the patients′ survival duration.
