3Consensus on the digestive endoscopic tunnel technique显示文摘With the digestive endoscopic tunnel technique(DETT), many diseases that previously would have been treated by surgery are now endoscopically curable by establishing a submucosal tunnel between the mucosa and muscularis propria(MP). Through the tunnel, endoscopic diagnosis or treatment is performed for lesions in the mucosa, in the MP, and even outside the gastrointestinal(GI) tract.At present, the tunnel technique application range covers the following:(1)Treatment of lesions originating from the mucosal layer, e.g., endoscopic submucosal tunnel dissection for oesophageal large or circular early-stage cancer or precancerosis;(2) treatment of lesions from the MP layer, per-oral endoscopic myotomy, submucosal tunnelling endoscopic resection, etc.; and(3) diagnosis and treatment of lesions outside the GI tract, such as resection of lymph nodes and benign tumour excision in the mediastinum or abdominal cavity. With the increasing number of DETTs performed worldwide, endoscopic tunnel therapeutics, which is based on DETT, has been gradually developed and optimized. However, there is not yet an expert consensus on DETT to regulate its indications, contraindications, surgical procedure, and postoperative treatment.The International DETT Alliance signed up this consensus to standardize the procedures of DETT. In this consensus, we describe the definition, mechanism,and significance of DETT, prevention of infection and concepts of DETTassociated complications, methods to establish a submucosal tunnel, and application of DETT for lesions in the mucosa, in the MP and outside the GI tract(indications and contraindications, procedures, pre-and postoperative treatments, effectiveness, complications and treatments, and a comparison between DETT and other operations).Ning-Li Chai Hui-Kai Li En-Qiang Linghu Zhao-Shen Li Shu-Tian Zhang Yu Bao Wei-Gang Chen Philip WY Chiu Tong Dang Wei Gong Shu-Tang Han Jian-Yu Hao Shui-Xiang He Bing Hu1 Bing Hu2 Xiao-Jun Huang Yong-Hui Huang Zhen-Dong Jin Mouen A Khashab James Lau Peng Li Rui Li De-Liang Liu Hai-Feng Liu Jun Liu Xiao-Gang Liu Zhi-Guo Liu Ying-Cai Ma Gui-Yong Peng Long Rong Wei-Hong Sha Pateek Sharma Jian-Qiu Sheng Shui-Sheng Shi Dong Wan Seo Si-Yu Sun Gui-Qi Wang Wen Wang Qi Wu Hong Xu Mei-Dong Xu Ai-Ming Yang Fang Yao Hong-Gang Yu Ping-Hong Zhou Bin Zhang Xiao-Feng Zhang Ya-Qi Zhai 2019World Journal of Gastroenterology2019,25,7:5
4Hepatic flow is an intraoperative predictor of early allograft dysfunction in whole-graft deceased donor liver transplantation: An observational cohort study显示文摘BACKGROUND Early allograft dysfunction(EAD)after liver transplantation(LT)is an important cause of morbidity and mortality.To ensure adequate graft function,a critical hepatocellular mass is required in addition to an appropriate blood supply.We hypothesized that intraoperative measurement of portal venous and hepatic arterial flow may serve as a predictor in the diagnosis of EAD.AIM To study whether hepatic flow is an independent predictor of EAD following LT.METHODS This is an observational cohort study in a single institution.Hepatic arterial blood flow and portal venous blood flow were measured intraoperatively by transit flow.EAD was defined using the Olthoff criteria.Univariate and multivariate analyses were used to determine the intraoperative predictors of EAD.Survival analysis and prognostic factor analysis were performed using the Kaplan-Meier and Cox regression models.RESULTS A total of 195 liver transplant procedures were performed between January 2008 and December 2014 in 188 patients.A total of 54(27.7%)patients developed EAD.The median follow-up was 39 mo.Portal venous flow,hepatic arterial flow(HAF)and total hepatic arterial flow were associated with EAD in both the univariate and multivariate analyses.HAF is an independent prognostic factor for 30-d patient mortality.CONCLUSION Intraoperative measurement of blood flow after reperfusion appears to be a predictor of EAD;Moreover,HAF should be considered a predictor of 30-d patient mortality.Pablo Lozano Lominchar Maitane Igone Orue-Echebarria Lorena Martín Cristina Julia Lisbona María Magdalena Salcedo Luis Olmedilla Hemant Sharma Jose Manuel Asencio JoséAngel López-Baena 2019World Journal of Hepatology2019,11,9:4
5Evaluation of immunogenicity and reactogenicity of recombinant DNA hepatitis B vaccine produced in India显示文摘AIM: (1) To gain information on immune responses to an accelerated schedule of 0, 1, and 2 mo in paramedical staff and BDS students who are at an increased risk of getting hepatitis B infection and come under high risk groups. (2) To assess the efficacy and safety of EnivacHB in different age groups, using genetically modified yeast strain Pichia pastoris, a new recombinant hepatitis B vaccine developed and manufactured in India.METHODS: A prospective, comparative, and single blinded trial of rapid (0, 1, and 2 mo) hepatitis B immunization schedulewas reported. A total of three hundred and seven (212 females and 95 males) healthy volunteers divided into three age groups (18-29, 30-39,and 40-49) were enrolled after screening for markers of hepatitis B. All the volunteers received 20 mg of the vaccine intramuscularly at 0, 1, and 2 mo.RESULTS: Geometric mean titers were calculated pre and post vaccination. Before immunization the GMT was 0.0124 mIU/mL. One month after the administration of the third dose of recombinant vaccine 296/307 (96.5%)subjects achieved seroprotective levels of anti-HBs. The geometric mean anti-HBs titers achieved after one month of the third dose was 2 560.0 mIU/mL. The geometric mean anti-HBs titer of males was 2 029.0 mIU/mL, while that of the females was 2 759.0 mIU/mL. In the age group of 18-29 years, anti-HBs titer was 3 025.0 mIU/mL, while that in the age group of 30-39 years was 2096.0 mIU/mL. In third age group of 40-49 years, antiHBs titer was 1 592.0 mIU/mL. Hyper-responses (antiHBs≥100 mIU/mL) were shown in 88.0% (271/307) of subjects. Eleven (3.5%) subjects responded poorly to the vaccine in the age group of 40-49 years. There was only mild pain at the site of injection otherwise there were no other adverse drug reactions (ADRs).CONCLUSION: This vaccine (Enivac-HB) is safe and efficacious, providing significant protection after the third dose and rapid hepatitis B immunization schedule of 0, 1, and 2 mo can be recommended whenever rapid protection is the goal.Zahid Hussain Syed S Ali Syed A Husain Mohammad Raish Deepika R Sharma Premashis Kar 2005World Journal of Gastroenterology2005,11,45:3
6Role of angiotensin-converting enzyme inhibitors and angiotensin receptor blockers in cryoballoon ablation outcomes for paroxysmal atrial fibrillation显示文摘BACKGROUND Cryoballoon ablation(CBA)is recommended for patients with paroxysmal atrial fibrillation(AF)refractory to antiarrhythmic drugs.However,only 80%of patients benefit from initial CBA.There is growing evidence that pretreatment with angiotensin-converting enzyme inhibitors(ACEIs)and angiotensin receptor blockers(ARBs)decreases the recurrence of AF postablation,particularly in nonparoxysmal AF undergoing radiofrequency ablation.The role of ACEIs and ARBs in patients with paroxysmal AF in CBA remains unknown.We decided to investigate the role of ACEIs and ARBs in preventing the recurrence of atrial arrhythmia(AA)following CBA for paroxysmal AF.AIM To investigate the role of ACEIs and ARBs in preventing recurrence of AA following CBA for paroxysmal AF.METHODS We followed 103 patients(age 60.6±9.1 years,29%women)with paroxysmal AF undergoing CBA 1-year post procedure.Recurrence was assessed by documented AA on electrocardiogram or any form of long-term cardiac rhythm monitoring.A multivariable Cox proportional hazard model was used to assess if ACEI or ARB treatment predicted the risk of AA recurrence.RESULTS After a 1-year follow-up,19(18.4%)participants developed recurrence of AA.Use of ACEI or ARB therapy was noted in the study population.Patients on ACEI/ARB had a greater prevalence of hypertension and coronary artery disease.On a multivariate model adjusted for baseline demographics and risk factors for AF,ACEI or ARB therapy did not prevent recurrence of AA following CBA(P=0.72).Similarly,on Kaplan–Meier analysis pretreatment with ACEI/ARB did not predict the time to first recurrence of AA(P=0.2173).CONCLUSION In our study population,preablation treatment with an ACEI or ARB had no influence on the recurrence of AA following CBA for paroxysmal AF.Ibragim Al-Seykal Abhishek Bose Parag A Chevli Zeba Hashmath Nitish Sharma Ajay K Mishra Douglas Laidlaw 2022World Journal of Cardiology2022,14,10:2
7Cell-type specificity of β-actin expression and its clinicopathological correlation in gastric adenocarcinoma显示文摘AIM:To investigate cell type specific distribution ofβ-actin expression in gastric adenocarcinoma and its correlation with clinicopathological parameters.METHODS:β-actin is a housekeeping gene,frequently used as loading control,but,differentially expresses in cancer.In gastric cancer,an overall increased expression ofβ-actin has been reported using tissue disruptive techniques.At present,no histological data is available to indicate its cell type-specific expression and distribution pattern.In the present study,we analyzedβ-actin expression and distribution in paired normal and tumor tissue samples of gastric adenocarcinoma patients using immunohistochemistry(IHC),a tissue non-disruptive technique as well as tissue disruptive techniques like reverse transcriptase-polymerase chain reaction(RT-PCR)and western blotting.Correlation ofβ-actin level with clinicopathological parameters was done using univariate analysis.RESULTS:The results of this study showed significant overexpression,at both mRNA and protein level in tumor tissues as confirmed by RT-PCR(1.47±0.13 vs2.36±0.16;P<0.001)and western blotting(1.92±0.26 vs 2.88±0.32;P<0.01).IHC revealed thatβ-actin expression is majorly distributed between epithelial and inflammatory cells of the tissues.Inflammatory cells showed a significantly higher expression compared to epithelial cells in normal(2.46±0.13 vs 5.92±0.23,P<0.001),as well as,in tumor tissues(2.79±0.24 vs6.71±0.14,P<0.001).Further,comparison of immunostaining between normal and tumor tissues revealed that both epithelial and inflammatory cells overexpressβ-actin in tumor tissues,however,significant difference was observed only in inflammatory cells(5.92±0.23vs 6.71±0.14,P<0.01).Moreover,combined expression in epithelial and inflammatory cells also showed significant increase(4.19±0.15 vs 4.75±0.14,P<0.05)in tumor tissues.In addition,univariate analysis showed a positive correlation ofβ-actin level of inflammatory cells with tumor grade(P<0.05)while epithelial cells exhibited negative correlation(P>0.05).CONCLUSION:In gastric cancer,β-actin showed an overall higher expression predominantly contributed by inflammatory or tumor infiltrating immune cells of the tissue microenvironment and correlates with tumor grade.Shafqat A Khan Monica Tyagi Ajit K Sharma Savio G Barreto Bhawna Sirohi Mukta Ramadwar Shailesh V Shrikhande Sanjay Gupta 2014World Journal of Gastroenterology2014,20,34:2

10HPLC analysis of camptothecin content in various parts of Nothapodytes foetida collected on different periods显示文摘Objective:To investigate the content of topoisomerase I-DNA inhibitor alkaloid camptothecin(CPT) from various parts of Nothapodytes foetida(N.foetida) collected from the month of October to February.Methods:The content of CPT was quantified in the methanolic extract of various parts of N.foetida using high performance liquid chromatography(UPLC).Quantification was performed with the regression analysis and the method was validated as per ICH guidelines. Results:The results revealed that maximum concentrations of camptothecin were found in root(2.62%) collected in the month of February followed by fruits(January,1.22%),stem(January,0.81%) and leaves(February,0.70%).Roots were found to have 3-fold higher concentration of CPT than the leaves and stem,while the fruits showed 2-fold higher concentration.Maximum concentration of camptothecin in fruits was observed in month of January,when they were not fully mature, which was 2-fold higher than that of young and fully mature fruits.Conclusions:These findings indicate that the synthesis of CPT differs in different parts of N.foetida and the content varies periodically.AG Namdeo A Sharma 2012Asian Pacific Journal of Tropical Biomedicine2012,2,5:2
