ABSTRACT
Objective To investigate the clinical value of probiotics in the treatment of patients with nonal -coholic fatty liver disease ( NAFLD) .Methods The clinical data of 100 patients with NAFLD were retrospectively analyzed.According to different treatment methods ,the patients were divided into two groups ,with 50 cases in each group.The control group received basic treatment ,the observation group received probiotics treatment on the basis of the control group .The treatment effects of the two groups were analyzed .Results The total effective rate in the obser-vation group (54.00%) was significantly higher than that in the control group (30.00%)(χ2 =5.911,P=0.015) .After treatment,the ALT,TG,HOMA-R,TNF-α,D-lactic acid,endotoxin levels in the observation group were significantly better than those in the control group (all P<0.05).The incidence rate of adverse reactions between the two groups had no statistically significant difference (4.00% vs.2.00%,χ2 =0.343,P =0.558).Conclusion Probiotics in the treatment of NAFLD can reduce the intestinal permeability ,improve the intestinal endotoxemia and the prognosis of the patients .
ABSTRACT
Objective To study the different oral compound polyethylene glycol electrolyte powder on the effect of bowel preparation before colonoscopy.Methods A total of 602 inpatients or outpatients were selected from department of gastroenterology,and they were randomly divided into tranditional group(n =288)and improvement group(n =314).All patients took a dose of two box of compound polyethylene glycol electrolyte powder 4 hours before colonoscopy.Endoscopic doctor investigated the antibiotic tolerance,adverse reactions,heart rate,blood pressure,blood electrolytes and blood glucose during treatment in form of questionnaire with single blind Bosdon bowel preparation scale (BBPS)score.Results The BBPS scores of the tranditional group and improvement group were (7.03 ± 1.24)points,(7.82 ±1.12)points,the score of the improvement group was significantly higher than the traditional group(t =2.259,P 0.05 ],althought the improvement group was shorter than the tranditional group. Conclusion The modified way of oral compound polyethylene glycol electrolyte powder not only can improve the qulity of intestinal cleaning,but also acts as a more effective method in preparation of colonoscopy due to its high tolerance, good comfort,less pain and high acceptance of patients.Therefore,it is worthy of clinical promotion and application.
ABSTRACT
Objective To observe the possible effect of inactivated schistosome ova on the expression of intestinal epithelial tight junctions ZO-1 and Occludin gene in mouse colitis induced by tinitrobenzene sulfonic acid (TNBS) and its mechanism. Methods Fifty mice were divided into control group (group A, n= 10),TNBS plus normal saline(NS) group(group B, n= 20) and TNBS plus inactivated schistosome ova group(group C, n= 20). Group C was exposed to 10 000 freeze-killed schistosome ova by intraperitoneal injection at day 14 and day 3 before colitis induction. Meanwhile,group B was exposed to 1 ml NS by intraperitoneal injection. The mice in group B and C were challenged with 3 mg TNBS to induce colitis. All mice were killed 7-day after colitis induction and assessed with following variables including mortality, pathological change with HE staining of colon.The transcription levels of ZO-1 and Oceludin in colon tissues were examined using Real-time PCR.The expression and distribution of ZO-1 and Occludin proteins were detected by Western blotting and immunohistochemistry. ResultsIn comparison with group B inactivated schistosome ova most effectively reduced the mortality (30% vs 15 %) and histopathologic severity of TNBS-induced colitis (4.21±0.40 vs 1.74±0.10). The transcription levels of ZO-1 and Occludin in group B were decreased compared with those in group A and group C (P<0.01). When compared with group B,group C showed a significant elevation of the alteration of ZO-1, Occludin proteins expression and localization. Conclusion The results clearly show that schistosome ova treatment reduced the severity of experimental colitis through the regulation of tight junction proteins.
ABSTRACT
Objective To investigate the effect of Schistosoma japonicum ova on the expression of intestinal NOD2/CARD15 in the mice induced by 2,4,6-trinitrobenzesulfonic acid (TNBS). Methods Mice (n=50) in the experiment were randomly allocated into 3 groups: control group (n=10), TNBS+saline (n=20) and TNBS+Schistosoma japonicum ova (n=20). TNBS enema (100 mg/kg) was applied to the two TNBS groups in order to establish a colonitis model. Schistosoma japonicum ova was administered i.p. on the 14~(th) and 3~(rd) day before the instillation of haptenating agent. All mice were killed on the 7~(th) day after colitis induction. The transcription level of NOD2 in colon tissues was measured by Real time PCR, and the expression of NOD2 protein was measured by Western blot. Results The transcription and protein levels of NOD2 in TNBS-induced mice increased statistically compared with those of the normal group (P<0.05). Compared with the TNBS-induced mice, Schistosoma japonicum ova-treated ones exhibited a statistical reduction of gene and protein expression (P<0.05). Conclusions TNBS-treated mice exhibited a statistical increased expression of NOD2/CARD15, Schistosoma japonicum ova treatment reduced the severity of experimental colitis through down-regulating NOD2/CARD15.
