ABSTRACT
Objective To preliminarily evaluate the clinical efficacy of endoscopic argon plasma coagulation (APC) combined with sub-mucosal injection of norepinephrine saline in the treatment of radiation proctitis (RP),especially for refractory RP.Methods Clinical data of 22 RP patients were retrospectively analyzed.The severity of RP was evaluated by a modified endoscopy scoring system (A) or Sherman's classification (B).The criteria of successful treatment are the improvement of clinical symptoms or the cessation of bleeding (or only occasional traces of blood on the stools that do not need further treatment).Results All 22 patients were successfully treated.Among them,18 patients (82％) had no bleeding.According to the classification of A,15 patients (68％) had mild proctitis and 7(32％) experienced severe proctitis.Based on B classification,9 patients (41％) were categorized as mild proctitis and 13(59％) as severe proctitis.Using the classification of A,the number of treatment sessions was significantly correlated with the endoscopic grade (or endoscopic total score) (Spearman's r=0.86,P＜0.001).Conclusions Preliminary evidence demonstrates that endoscopic APC combined with sub-mucosal injection of norepinephrine saline is not only effective for mild and moderate RP,but also maintains long-term efficacy for refractory RP.Modified endoscopy scoring system (A) assessment is more suitable for clinical application compared with B assessment.

Objective@#To preliminarily evaluate the clinical efficacy of endoscopic argon plasma coagulation (APC) combined with sub-mucosal injection of norepinephrine saline in the treatment of radiation proctitis (RP), especially for refractory RP.@*Methods@#Clinical data of 22 RP patients were retrospectively analyzed. The severity of RP was evaluated by a modified endoscopy scoring system (A) or Sherman′s classification (B). The criteria of successful treatment are the improvement of clinical symptoms or the cessation of bleeding (or only occasional traces of blood on the stools that do not need further treatment).@*Results@#All 22 patients were successfully treated. Among them, 18 patients (82%) had no bleeding. According to the classification of A, 15 patients (68%) had mild proctitis and 7(32%) experienced severe proctitis. Based on B classification, 9 patients (41%) were categorized as mild proctitis and 13(59%) as severe proctitis. Using the classification of A, the number of treatment sessions was significantly correlated with the endoscopic grade (or endoscopic total score)(Spearman’s r=0.86, P<0.001).@*Conclusions@#Preliminary evidence demonstrates that endoscopic APC combined with sub-mucosal injection of norepinephrine saline is not only effective for mild and moderate RP, but also maintains long-term efficacy for refractory RP. Modified endoscopy scoring system (A) assessment is more suitable for clinical application compared with B assessment.
ABSTRACT
OBJECTIVE:To study the antitumor activity and immunomodulatory effects of theasinesin on mice transplanted tumor and tumor-bearing mice.METHODS: With three mice transplanted tumor models i.e. Ehrlich ascites tumor, sarcoma 180 and hepatic carcinoma H22,we strdied the antitumor activity of theasinesin .The immunomodulatory effects of theasinesin on S180-bearing mice were measured by delayed type hypersensitivity(DTH), cleaning charcoal particles method, and splenocyte proliferation test .RESULTS: Theasinesin at doses of 400,200, 50mg/kg could markedly inhibite the growth of Ehrlich ascites tumor(solid tumor) .Although theasinesin didn't have significant inhibitory effects on sarcoma 180 and hepatic carcinoma H22 in routine oral administration, the average inhibitory rates of each group, in manner of preventive administration, were all greater than 30% .Theasinesin at doses of 50,100,200mg/kg could significantly restore the decreased DTH in S180-bearing mice. It could also markedly increase K, a and promote proliferation of activated T cells in S180- bearing mice. CONCLUSION :Theasinesin has significant inhibitory effects on mice transplanted tumors. It can also enhance the decreased immunological function on tumor-bearing mice.
ABSTRACT
Objectives:To evaluate the effect of partial parenteral nutrition(PPN) with fat emulsion on liver function and energy metabolism in patients with liver cirrhosis. Methods:67 cirrhotic patients were divided into two groups randomly and given PPN with(group 1, 33 cases) or without(group 2, 34 cases)fat emulsion for two weeks separately.Their liver function test,fasting blood glucose(FGB) and insulin(Ins) and postprandial blood glucose at 2nd hour (PPBG 2 h),lipid metabolism and arteral ketone body ratio(AKBR) were examined respectively before and after PPN. Results:Having been given PPN for two weeks,ALT and TB levels were decreased in group 1( P 0.05 ). Alb level was decreased in group 2( P 0.05). TG,CH and PL levels were normal in group 1( P 0.05).AKBR was increased in group 1( P
