ObjectiveTo investigate the risk factors for open pancreatic necrosectomy (OPN), an effective treatment method for severe acute pancreatitis (SAP) after the failure of percutaneous catheter drainage (PCD), in patients with SAP. MethodsA retrospective analysis was performed for 156 patients with SAP who underwent surgical intervention based on the step-up approach in The Affiliated Hospital of Zunyi Medical University from January 1, 2010 to June 30, 2018, and according to whether OPN was performed, the patients were divided into PCD group with 126 patients and PCD+OPN group with 30 patients. Related clinical data were collected, including age, sex, etiology, blood calcium on admission, white blood cell count on admission, whether CTSI score was >7, APACHE-Ⅱ score, Ranson score, presence or absence of peripancreatic fluid accumulation, presence or absence of infection, presence or absence of multiple organ failure (MOF), and whether PCD was performed at more than 1 week after admission. The t-test was used for comparison of continuous data between groups, and the chi-square test was used for comparison of categorical data between groups; a multivariate logistic regression analysis was used to determine the independent predictive factors for OPN. ResultsThe probability of OPN was 19.2% for SAP patients in the later stage. Compared with the PCD+OPN group, the PCD group had a significantly lower proportion of patients with MOF on admission [27.0% (34/126) vs 70.0% (21/30), χ2=19.642, P<0.01] and a significantly higher proportion of patients undergoing PCD at less than 1 week after admission [61.9% (78/126) vs 20.0% (6/30), χ2=17.121, P<0.01]. MOF on admission (odds ratio [OR]=5.343, 95% confidence interval [CI]: 1.832-15.583, P<0.05), initial PCD performed at more than 1 week after admission (OR= 5.518, 95% CI: 1.742-17.477, P<0.05), and infection on admission (OR=5.016, 95% CI: 1.322-19.378, P<0.05) were independent risk factors for subsequent OPN in SAP patients. ConclusionSAP with MOF on admission, initial PCD performed at more than 1 week after admission, and SAP with infection on admission are independent risk factors for subsequent OPN in SAP patients undergoing PCD in the early stage based on the step-up approach. Timely identification of related risk factors helps to grasp the timing of OPN in clinical practice and improve the clinical prognosis of SAP patients.

Hepatic ischemia-reperfusion injury (HIRI) is the main cause of liver damage and even multiple organ failure after complex liver surgery.When liver ischemia reperfusion occurs,the non-coding RNAs in the liver tissue is dysregulated and part of the non-coding RNAs with abnormal expression is involved in HIRI regulation.Non-coding RNAs to may be the intervention target for reducing HIRI.This article summarized the types and related functions of non-coding RNAs,the role of different non-coding RNAs in HIRI,and the interconnections between various non-coding RNAs in HIRI.

Fungal infection is an important clinical problem for patients with immune deficiency or immunosuppression. With deadly fungus infection case increasing, the development of antifungal vaccine attracts the attention of researchers. Dendritic cell (DC) is the unique antigen presenting cell (APC) to trigger the antifungal immune reaction, and recent studies indicate that the targeted vaccination strategy based on DC have prospective antifungal potentials. In this paper, we review the antifungal immunity mechanism and recent development of the targeted DC antifungal strategy.
