Chinese Journal of Digestion 2010;30(2):81-86
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.

Fudan University Journal of Medical Sciences 2010;37(2):162-166
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.

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).The taste scores were (1.89 ±0.07)points,(1.25 ±0.09)points (t =2.624,P <0.05),the fully taking rates were 90.28%,95.86%(χ2 =7.375,P <0.05 ),and the second taking rates were 88.54%,93.95%(χ2 =5.566,P <0.05).In contract,the score of adverse reactions of the improvement group was significantly lower than that of the traditional group [(2.58 ±0.07)points vs(2.22 ±0.09)points,t =2.068,P <0.05].There was no significant difference of colonoscopy time between the two groups[(10.78 ±4.34)min vs (9.89 ± 1.77)min,t =1.766,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.

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 .

Children are at high risk for burns, and severe burns can lead to the destruction of their skin's physiological structure, causing excruciating pain. Burned children are highly prone to adverse emotions such as anxiety and panic, which can impact the outcome of their treatment and rehabilitation. Therefore, managing pain and anxiety is crucial in the care of burned children. In 2022, " Evidence-based practical guideline for procedural pain management and sedation for burn pediatrics patients undergoing wound care procedures" was published in the journal " Annals of Medicine and Surgery" by Ethiopia expert panel engaged in burn rehabilitation after conducting a systematic literature search and evaluation, aiming to guide clinical management of related diseases in a more scientifical and standardized manner. This paper aims to inform clinical healthcare professionals in China to understand the latest relevant evidence, and to provide ideas and basis for effective management of pain and accompanying anxiety in children with burns, and standardized operations of relevant practice.

According to the International League Against Epilepsy (ILAE) standards, the Newborn Working Group of the ILAE put forward 6 necessary questions about the management of neonatal anti-seizure medication and gave evidence-based recommendations in 2023. The basic framework is systematic review+expert consensus. The clinical recommendations of ILAE guidelines 2023 and the similarities and differences between ILAE guidelines 2023 and ILAE guidelines 2011 were analyzed and interpreted in this paper, in order to provide reference for colleagues involved in neonatal convulsion management in China.
