In recent years, the importance of guanylate cyclase-C (GC-C) in digestive system diseases has received more and more attention. It plays a key role in regulating water and electrolyte balance, maintaining gastrointestinal function, relieving abdominal pain, controlling inflammation, regulating intestinal microecology, inhibiting tumor growth and regulating cell proliferation, and is considered as a potential therapeutic target for digestive tract diseases. This article reviews the role of GC-C in digestive system diseases and related intervention studies of agonists linaclotide and plecanatide in recent years, in order to better understand its intrinsic function and further guide the diagnosis and treatment of related clinical diseases.
ObjectiveTo systematically review the efficacy and safety of early abdominal paracentesis drainage (APD) in patients with severe acute pancreatitis (SAP). MethodsThe PubMed, Cochrane Library, Web of Science, CNKI, WanFang Data, and VIP databases were searched to collect randomized controlled trials and cohort studies on the management of SAP via early APD from inception to December 10, 2022. Two reviewers independently screened the literature, extracted data, and assessed the risk of bias of the included studies. Meta-analysis was then performed using RevMan 5.4 software and Stata 17.0 software. ResultsEighteen studies were included, with a total sample size of 2 685 patients. The meta-analysis showed that early APD could decrease mortality (OR=0.49, 95%CI 0.35 to 0.69, P<0.01) and the incidences of multiple organ failure (OR=0.56, 95%CI 0.45 to 0.71, P<0.01), ARDS (OR=0.54, 95%CI 0.41 to 0.71, P<0.01), and infectious complications (OR=0.72, 95%CI 0.57 to 0.92, P<0.01) and also reduce the need for further interventions and the total cost incurred during hospitalization, reduce the length of hospital stay, and reduce the number of days spent in the intensive care unit. However, there were no significant differences in the incidence of pneumonia, bacteremia, and sepsis between the two groups. ConclusionThe treatment of SAP via early APD, which has high clinical value, could decrease the incidence of multiple organ failure, improve the prognosis of patients, and reduce the associated mortality rate. Moreover, APD does not increase the risk of infection-related complications. Due to the limited quantity and quality of the included studies, more high-quality studies are needed to verify the above conclusion.
ObjectiveTo explore the protective effects of abdominal paracentesis drainage (APD) on pancreatitis-associated liver injury in the early phase of severe acute pancreatitis (SAP). MethodsOne hundred and fourteen consecutive patients with SAP, admitted to the General Hospital of Western Theater Command from January 2015 to January 2021, were included in this retrospective study. The patients were divided into the APD group (n=61) and the non-APD group (n=53) based on whether they underwent APD treatment within 72 h of admission. The variables including baseline data, liverfunction tests, inflammation indexes, severity scores and other variables of the two groups were statistically analyzed. ResultsThe hospital mortality in the APD group was lower than that in the non-APD group (8.2% vs. 22.6%, P=0.031). These severity scores (including APACHE Ⅱ score, Ranson score and modified Marshall score) and inflammation indexes (including C-reactive protein, interleukin-6, interleukin-1 and tumor necrosis factor-α) in the APD group were all lower than those in the non-APD group (P＜0.05). In terms of liver function related indexes, the levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), γ-glutamyl transpeptidase (GGT), total bilirubin (TBIL), and direct bilirubin (DBIL) after treatment in both two groups were significantly lower than those before treatment (P＜0.05). The levels of ALT, AST, TBIL and DBIL after treatment in the APD group were lower than those in the non-APD group (P＜0.05), and the levels of prealbumin and albumin after treatment in the APD group were higher than those in the non-APD group (P＜0.05), but there were no significant differences in the levels of alkaline phosphatase, GGT and 5′ -nucleotidase after treatment in the two group (P＞0.05). ConclusionFor SAP patients with ascitic fluid, application of APD can attenuate liver injury and improve liver function in the early stage of SAP.
Transparent reporting of randomized trials is essential to facilitate critical appraisal and interpretation of results. Factorial trials, in which two or more interventions are assessed in the same set of participants, have unique methodological considerations. However, reporting of factorial trials is suboptimal. A consensus-based extension to the consolidated standards of reporting trials (CONSORT) 2010 statement for factorial trials was developed based on the enhancing the quality and transparency of health research (EQUATOR) methodological framework. In the study, we introduced and interpreted the extension of the CONSORT 2010 statement for factorial design in which 16 items were modified and one new item was added and presented an example of a factorial trial in mental health to provide guidance on the reporting of factorial randomized trials.
