ABSTRACT

Objective To discuss application value of intestinal electromyography in patients with hepatic cirrhosis and to observe intestinal myoeletric activity.Methods There were 65 cases of hepatic cirrhosis in expermental group and 30 cases in control group. All the cases were recorded body surface intestinal electromyography using gastrointestinal myoelectric analyzer(WCDF-4B, Hefei , P.R.China). The parameters included average peak range-Ap, main frequency-Fp, average over zero frequency-Fz and special wave form were surveyed.Results Sharp higher Fz abnormal rate and emergence rate of special wave form in hepatic cirrhosis group were higher than in control group,P0 05.Conclusions In hepatic cirrhosis group,Fz was much higher than that in control group. And the intestinal myoelectric activity increased in the patients with hepatic cirrhosis,which represented by appearance of characteristic wave form that was frequent micromigration wave as well as load wave. Those changes accounted for heighten and irregularity of excitability intestinal myoelectric activity. Moreover, it will increase for the incidence of abnormality of intestinal myoelectric activity along with damage degree of hepatic function. Intestinal electromyography is a reliable method to judge intestinal myoelectric activity, the method has characteristics of harmless,free pain, convenient, safty and steady.

ABSTRACT

Purpose:To study the mutual relationships between apoptosis,cell proliferation correlative gene PCNA and tumor suppressor gene P27 Kip1 as well as to investigate if they have something to do with the occurrence,development,and prognosis in esophagus squamous cell carcinoma.Methods:47 cases of primary esophagus squamous cell carcinoma were put into investigative group whose tumor samples from operation resection were studied. 20 cases with normal esophagus cell mucous membrane tissue were put into the control group. Expression level of PCNA,P27 Kip1 was detected by immunohistochemistry method (S-ABC) in both groups. Apoptotic index was detected by TdT mediated deoxyuridylic acid(dUMP)nicking end labeling (TUNEL method) in both groups.Results:①In the group of 47 cases of esophagus squamous cell carcinoma,there were 17 cases of positive expression in P27 Kip1 ,and the positive rate was 36.17% , average proliferation index(PI) was 45.86?19.11%,average apoptotic index is 1.05%?0.59%,ratio of PI/AI is 57.37? 45.17 ,all of which were statistically significant for difference between normal tissue and carcinoma in esophagus squamous cell (P
