Abstract
Aim Cardiac injury, reflected by the measured concentrations of chemicals released from injured cardiac muscle, is common in acute pancreatitis (AP). However, there is no adequate evidence assessing the impact of cardiac injury on AP-related outcomes. Creatine kinase-myocardial band (CK-MB) mainly exists in the myocardium. Therefore, we sought to evaluate the relationship between the increase in CK-MB and the adverse clinical outcomes of AP. Methods This propensity score-matched study analyzed AP patients admitted to the Department of Gastroenterology in the First Affiliated Hospital of Nanchang University from June 2017 to July 2022. Propensity score matching and multivariate logistic regression analysis were used to explore the relationship between CK-MB elevation and AP outcome variables. Results A total of 5,944 patients were screened for eligibility, of whom 4,802 were ultimately enrolled. Overall, 896 (18.66%) of AP patients had elevated (>24 U/ml) CK-MB levels, and 895 (99.89%) were paired with controls using propensity score matching. The propensity score-matched cohort analysis demonstrated that mortality (OR, 5.87; 95% CI, 3.89-8.84; P < 0.001), severe acute pancreatitis (SAP) (OR, 2.74; 95% CI, 2.23-3.35; P < 0.001), and infected necrotizing pancreatitis (INP) (OR, 3.40; 95% CI, 2.34-4.94; P < 0.001) were more frequent in the elevated CK-MB (>24 U/ml) group than in the normal CK-MB (≤ 24 U/ml) group. Using the multivariate logistic regression analysis, elevated CK-MB levels were independently associated with increased mortality (OR, 2.753, 95% CI, 2.095-3.617, P < 0.001), SAP incidence (OR, 2.223, CI, 1.870-2.643, P < 0.001), and INP incidence (OR, 1.913, 95% CI, 1.467-2.494, P < 0.001). CK-MB elevation was an independent risk factor for adverse clinical outcomes in AP patients. Conclusion CK-MB elevation was significantly related to adverse outcomes in AP patients, which makes it a potentially useful laboratory parameter for predicting adverse clinical outcomes of AP.

Abstract
BACKGROUND Although immune checkpoint inhibitor (ICI) therapy has improved the prognosis of unresectable hepatocellular carcinoma (HCC), it has also resulted in unique immune-related adverse events (irAEs). The relationship between irAE and treatment outcomes in ICI-treated unresectable HCC patients remains unknown.
AIM To elucidate the correlation between immune-related toxic effects and prognosis in patients with unresectable HCC treated with pembrolizumab.
METHODS From March 2019 to February 2021, a total of 190 unresectable HCC (Barcelona Clinic Liver Cancer C) patients receiving pembrolizumab treatment were retrospectively reviewed. Overall survival (OS) was the primary endpoint, while objective response rate (ORR), disease control rate (DCR), and time to progression (TTP) were secondary evaluation indexes. We assessed demographics, irAEs, and outcomes by retrospective review.
RESULTS One hundred and forty-three males and 47 females were included in the study. The ORR and DCR were 12.1% (23/190) and 52.1% (99/190), respectively. The median OS was 376 d [95% confidence interval (CI): 340-411 d] and the median TTP was 98 d (95%CI: 75-124 d). The overall incidence of treatment-related adverse events was 72.6% (138/190) and 10.0% of them were severe irAEs (grade ≥ 3). Child-Pugh B class, portal vein tumor thrombus, extrahepatic metastasis, and hypothyroidism were the independent risk factors for survival. Patients with hypothyroidism showed a longer OS [517 d (95%CI: 423-562) vs 431 d (95%CI: 412-485), P = 0.011] and TTP [125 d (95%CI: 89-154) vs 87 d (95%CI: 61-98), P = 0.004] than those without irAEs.
CONCLUSION Pembrolizumab-treated patients with unresectable HCC who experienced hypothyroidism have promising ORR and durable response. Hypothyroidism, an irAE, may be used as a clinical evaluation parameter of response to ICIs in unresectable HCC.

Abstract
Tumor endothelial cell marker 8 (TEM8) is a type I transmembrane protein, that has been widely studied in the areas of anthrax toxin infection and tumor angiogenesis. However, the role of TEM8 in the progression of epithelial ovarian cancer (EOC) remains unclear. In this study, we determined that TEM8 was highly expressed in ovarian cancer and associated with poor prognosis in EOC patients. In vitro experiments showed that TEM8 overexpression significantly promoted ovarian cancer proliferation. TEM8 overexpression also promoted the G0/G1 phase transition, migration, and invasion of ovarian cancer cells but suppressed apoptosis. Moreover, experimental verification confirmed that TEM8 overexpression increased the expression of Ki-67, cyclin D1, Bcl2/Bax, MMP2, MMP9, and VEGFA and the phosphorylation of Rac1/Cdc42, JNK, MEK, ERK, and STAT3 (Ser727). Subsequently, the addition of RAC1 (EHop-016) and MEK (PD98059) pathway inhibitors suppressed malignant behaviors in the TEM8 overexpression group, which robustly indicated that TEM8 activated Rac1/Cdc42/JNK and MEK/ERK/STAT3 signaling pathways. In addition, we also revealed that the transcription factor GATA2 bound to the TATTAGTTATCTTT site of the TEM8 promoter region and regulated its expression. In conclusion, our study may provide a new theoretical basis for TEM8 application as a clinical biomarker and potential target in EOC patients.

Abstract
OBJECTIVES Glycosylation alterations are indicative of tissue inflammation and neoplasia. However, there are no large-sample, real-world studies assessing the levels of serum carbohydrate antigen 125 (CA125) in patients with acute pancreatitis (AP). We aimed to identify the association between elevated CA125 levels and adverse clinical outcomes in AP. METHODS This was a retrospective cohort study with an analysis of 3939 patients with AP who were admitted to the First Affiliated Hospital of Nanchang University between January 2015 and September 2019 that used data from a prospectively maintained database. Multivariate logistic regression analysis and a propensity score-matched analysis were conducted to reveal the relationship between elevated CA125 levels and poor prognosis. RESULTS The overall prevalence of elevated CA125 (>35 U/mL) levels was 38.51% (1517/3939) in AP patients. Elevated CA125 levels were independently associated with higher risks of mortality (adjusted odds ratio (AdjOR), 1.82; 95% confidence interval (CI), 1.30-2.54; P < 0.001), severe acute pancreatitis (SAP) (AdjOR, 2.40; 95% CI, 2.00-2.88; P < 0.001), and infected pancreatic necrosis (IPN) (AdjOR, 3.54; 95% CI, 2.65-4.71; P < 0.001). The propensity score-matched cohort analysis also demonstrated that mortality (OR, 1.57; 95% CI, 1.06-2.23; P < 0.05), SAP (OR, 2.20; 95% CI, 1.77-2.73; P < 0.001), and IPN (OR, 2.79; 95% CI, 1.98-3.92; P < 0.001) were more common in the elevated CA125 group than in the normal CA125 group. CONCLUSIONS Elevated CA125 levels (>35 U/mL) are independently associated with adverse clinical outcomes in AP patients. These observations justify ongoing efforts to understand the role of CA125 in the pathogenesis and prognosis of AP.

Abstract
BACKGROUND Gastrointestinal (GI) dysfunction is a common and important complication of acute pancreatitis (AP), especially in patients with severe AP. Despite this, there is no consensus means of obtaining a precise assessment of GI function.
AIM To determine the association between acute gastrointestinal injury (AGI) grade and clinical outcomes in critically ill patients with AP.
METHODS Patients with AP admitted to our pancreatic intensive care unit from May 2017 to May 2019 were enrolled. GI function was assessed according to the AGI grade proposed by the European Society of Intensive Care Medicine in 2012, which is mainly based on GI symptoms, intra-abdominal pressure, and feeding intolerance in the first week of admission to the intensive care unit. Multivariate logistic regression analysis was performed to assess the association between AGI grade and clinical outcomes in critically ill patients with AP.
RESULTS Among the 286 patients included, the distribution of patients with various AGI grades was 34.62% with grade I, 22.03% with grade II, 32.52% with grade III, and 10.84% with grade IV. The distribution of mortality was 0% among those with grade I, 6.35% among those with grade II, 30.11% among those with grade III, and 61.29% among those with grade IV, and AGI grade was positively correlated with mortality (χ2 = 31.511, P < 0.0001). Multivariate logistic regression analysis showed that age, serum calcium level, AGI grade, persistent renal failure, and persistent circulatory failure were independently associated with mortality. Compared with the Acute Physiology and Chronic Health Evaluation II score (area under the curve: 0.739 vs 0.854; P < 0.05) and Ranson score (area under the curve: 0.72 vs 0.854; P < 0.01), the AGI grade was more useful for predicting mortality.
CONCLUSION AGI grade is useful for identifying the severity of GI dysfunction and can be used as a predictor of mortality in critically ill patients with AP.

Abstract
Objective: To explore the normal values for two-dimension solid state high resolution anorectal manometry (HRAM) in healthy adult volunteers. Methods: The healthy adult volunteers were recruited by advertisement and underwent solid state HRAM in the left lateral position. Anorectal pressures and rectal sensation were recorded and analyzed. Results: (1) A total of 126 Chinese healthy adult volunteers (male: 50 cases (39.7%); age: (37.5±14.2) years old ) were recruited in this study. (2) Mean anal resting pressure (MERP) was (71.8±17.3) mmHg (1 mmHg=0.133 kPa). Maximum anal resting pressure (MARP) was (79.3±17.8) mmHg, Maximum anal squeeze pressure (MSP) was (178.7±52.8) mmHg. Anal high pressure zone (HPZ) length was (3.4±0.6) cm. During simulated evacuation, residual anal pressure (RAP) was (63.8±20.5) mmHg, and anal relaxation rate (ARR) was (37.0±11.5)%. Rectal threshold volume for first sensation (FST), desire to defecate (DDT), urgency to defecate (UDT) and maximum discomfort (MDT) was (47.4±10.0) ml, (84.5±18.2) ml, (125.8±28.5) ml, and (175.5±36.1) ml, respectively. (3) Compared with female subjects, male subjects had higher MSP[(211.0±50.7) mmHg vs (157.5±42.5) mmHg], RAP[(71.6±18.1) mmHg vs (58.8±20.5) mmHg]and rectal MDT[(187.0±36.4) mmHg vs (168.0±34.1)mmHg], but lower ARR[(32.1±8.0)% vs (40.2±12.3)%], all P<0.01. (4) MERP, MARP, MSP and rectal MDT were higher in young group (≤40 years old), all P<0.05. Conclusions: These observations provide normal values for two-dimension solid state HRAM, which have significant difference between genders and different age groups.

Abstract
AIM: To investigate the inhibitory effects and mechanism of high mobility group box (HMGB)1 A-box in lipopolysaccharide (LPS)-induced intestinal inflammation.
METHODS: Overexpression of HMGB1 A-box in human intestinal epithelial cell lines (SW480 cells) was achieved using the plasmid pEGFP-N1. HMGB1 A-box-overexpressing SW480 cells were stimulated with LPS and co-culturing with human monocyte-like cell lines (THP-1 cells) using a Transwell system, compared with another HMGB1 inhibitor ethyl pyruvate (EP). The mRNA and protein levels of HMGB1/toll-like receptor (TLR) 4 signaling pathways [including HMGB1, TLR4, myeloid differentiation factor88 (MYD88), Phosphorylated Nuclear Factor κB (pNF-κB) p65] in the stimulated cells were determined by real-time polymerase chain reaction and Western blotting. The levels of the proinflammatory mediators [including HMGB1, interleukin (IL)-1β, IL-6 and tumor necrosis factor (TNF)-α] in the supernatants of the stimulated cells were determined by ELISA.
RESULTS: EP downregulated the mRNA and protein levels of HMGB1, inhibited the TLR4 signaling pathways (TLR4, MYD88 and pNF-κB p65) and reduced the secretion of proinflammatory mediators (HMGB1, IL-1β, IL-6 and TNF-α) in the SW480 and THP-1 cells activated by LPS but not in the unstimulated cells. Activated by LPS, the overexpression of HMGB1 A-box in the SW480 cells also inhibited the HMGB1/TLR4 signaling pathways and reduced the secretion of these proinflammatory mediators in the THP-1 cells but not in the transfected and unstimulated cells.
CONCLUSION: HMGB1 A-box, not only EP, can reduce LPS-induced intestinal inflammation through inhibition of the HMGB1/TLR4 signaling pathways.

Abstract
OBJECTIVES To assess the efficacy and safety of hybrid therapy compared to other pre-existing therapies and to new therapies. METHODS Through a search of PubMed, EMBASE, the Cochrane Central Register of Controlled Trials, and Conference Proceedings Citation Index, two independent reviewers systemically identified randomized, controlled trials that compared hybrid therapy to other pre-existing and new therapies. Dichotomous data were pooled to obtain the relative risk (RR) of the eradication rate, with 95% confidence intervals (CIs). RESULTS We identified 6 studies, 5 of which compared hybrid therapy and sequential therapy, and 3 of which compared hybrid therapy and concomitant therapy. Pooled estimates of the 5 randomized controlled trials (RCTs) revealed no significant differences between hybrid therapy and sequential therapy and no evidence of heterogeneity (I(2) = 0%; p = .803), the pooled RRs were 1.02 (95% CI: 0.93-1.12) (intention-to-treat (ITT)), and 1.03 (95% CI: 0.94-1.13) (per protocol (PP)). Pooled estimates of the 3 RCTs showed no significant differences between hybrid therapy and concomitant therapy with no evidence of heterogeneity (I(2) = 0%; p = .967), the pooled RRs were 0.99 (95% CI: 0.89-1.10) (ITT) and 0.99 (95% CI: 0.89-1.10) (PP). No significant differences in adverse events were noted among hybrid therapy, sequential therapy, and concomitant therapy ((RR: 1.13; 95% CI: 0.87-1.48; I(2) = 13.2%; p = .327), (RR: 0.89; 95% CI: 0.73-1.08; I(2) = 0%; p = .978) (ITT), respectively). After consideration of all treatment arms, the ITT eradication rates with hybrid therapy, concomitant therapy, and sequential therapy were 88.6, 86.3, and 84.7%, respectively. And the PP eradication rates were 92.1, 92.5, and 87.5%. No significant differences were observed between the groups in terms of compliance. CONCLUSIONS All three of these therapies yielded good eradication rates. Hybrid therapy could be an alternative to sequential therapy and concomitant therapy, but additional RCTs are needed to confirm this finding.

Abstract
Highly (100)-oriented and (110)-oriented (Ba0.65Sr0.35)TiO3 (BSTO) and (Ba0.65Sr0.35)TiO3/CaRuO3 (BSTO/CRO) heterostructure thin films, have been grown on Pt/Ti/SiO2/Si substrates prepared by pulsed laser deposition (PLD). The structure and surface morphology of the films have been characterized by X-ray diffraction (XRD) and scanning electron microscope (SEM). The dielectric constants of the films changes significantly with applied dc bias field and have high tunability of 76.3% and 78.1% at an applied field of 256.3 kV/cm, respectively for BSTO and BSTO/CRO thin films on Pt/Ti/SiO2/Si substrates. The tunability of the BSTO/CRO heterostructure thin films on Pt/Ti/SiO2/Si substrate was higher than that of the BSTO thin films on Pt/Ti/SiO2/Si substrate. The high tunability has been attributed to the (110) texture of the films and lager grain sizes.
