ABSTRACT
Treating from liver is an important thought to treat esophageal cancer.Regulating the liver has very important significance in the process of treating esophageal carcinoma,which embodies at regulating liver is the key of soothing emotional injuries of esophageal carcinoma,removing esophageal pathology product and coordinating rising-descending function of spleen and stomach,and improving accompainedg symptoms of esophageal cancer.The thought of treating from liver should be used throughout the whole process of the treatment.So we must pay morn attention to regulate the liver and prevent liver injury during the differentiation and treatment of esophageal carcinoma.
ABSTRACT
<p><b>OBJECTIVE</b>To evaluate therapeutic effect of Sishen Wan on experimental colitis, and explore its mechanism by expression of Bax/Bcl-2 mRNA, Fas/FasL in colonic tissue.</p><p><b>METHOD</b>Experimental colitis was induced by rectal administration of trinitrobenzene sulfonic acid (TNBS) dissolved in ethanol. The model animals were divided into four groups: the induced colitis but untreated group, the induced colitis groups treated with the high, middle, low dose of Sishen Wan, and the induced colitis group treated with salicylazosulfapyridine (SASP). After 10 day administration, the body weight, colonic wet weight, colonic weight index, colonic damage score and pathological change were evaluated, and the level of Fas and FasL by flow cytometry, Bax mRNA and Bcl-2 mRNA by reverse transcription polymerase chain reaction (RT-PCT).</p><p><b>RESULT</b>Compared with the model group, the colonic wet weight and colonic weight index were remarkably decreased in the middle dose of Sishen Wan group (P < 0.05). The colonic injury scores were significantly reduced after rats were treated with the three doses of Sishen Wan (P < 0.05). Representative restored features were observed including fewer inflammatory cellular infiltration and follicular hyperplasia, superficial and little ulcer with fibroplasia in colonic mucosa from the treated groups. The expression of Fas in the colonic mucosa was obviously down-regulated (P < 0.05) and the ratio of Bcl-2 mRNA/Bax mRNA was significantly up-regulated (P < 0.05) in the groups treated with the three doses of Sishen Wan.</p><p><b>CONCLUSION</b>Sishen Wan might postpone colonic epithelium apoptosis or improve inflammatory cell apoptosis by regulating the expression of Fas/ FasL and Bax/Bcl-2 mRNA in colonic tissue, which is possible potential path to effectively treat experimental colitis by enema.</p>

<p><b>OBJECTIVE</b>To observe effect of oral scorpio and scolopendra powder on T-cell subsets in peripheral blood and intestine from rats with collagen induced arthritis (CIA).</p><p><b>METHOD</b>60 rats were randomly divided into 6 groups: normal control group, model control group, low-dose scorpio and scolopendra group, middle-dose scorpio and scolopendra group, high-dose scorpio and scolopendra group, and type II collagen group. Rat's rheumatoid arthritis was induced by collagen II (C II). Level of T-cell subsets from peripheral blood and intestine was measured by flow cytometry.</p><p><b>RESULT</b>CD4+ T cellular level was obviously increased (P < 0.05 or P < 0.01) or kept increased tendency in peripheral blood and intestine from the model group compared with that of the normal group, while the ratio of CD4+/CD8+ in intestine was obviously descent but the contrary in peripheral blood (P < 0.05 or P < 0.01). CD4+, CD8+ T cellular level in intestine were obviously descent and the ratio of CD4+ /CD8+ increased in all treated groups when compared with in the model group (P < 0.05 or P < 0.01). However, CD4+ T cellular level and the ratio of CD4+/CD8+ in peripheral blood were remarkablely decreased.</p><p><b>CONCLUSION</b>The mechanism that scorpio and scolopendra could treat rat's rheumatoid arthritis may be regulating balance of T-lymphocyte subsets in peripheral blood and intestine.</p>
