Objective:To investigate the association of malnutrition based on Global Leadership Initiative on Malnutrition (GLIM) criteria with the disease activity and clinical outcomes in hospitalized ulcerative colitis (UC) patients.Methods:Clinical data of 115 patients with UC hospitalized in the Affiliated Hospital of Qingdao University from September 2019 to March 2023 were prospectively analyzed. GLIM and European Society for Clinical Nutrition and Metabolism (ESPEN) 2015 criteria were used for the diagnosis of malnutrition, allowing the analysis of consistency between two diagnostic criteria for malnutrition. The relationship between malnutrition based on GLIM criteria and disease activity and clinical outcome was further investigated. The risk factors of adverse clinical outcomes in UC patients were analyzed using binary logistic regression.Results:GLIM and ESPEN 2015 diagnostic criteria showed high correlation and consistency (AUC=0.875, P<0.001; K=0.809, P<0.001). According to GLIM criteria, the prevalence of malnutrition among hospitalized UC patients was 32.17% (37 cases). Compared with non-malnourished UC patients, the modified Mayo score and C-reactive protein level of malnutrition patients were higher ( P<0.005), and the proportion of patients with severe disease activity was higher ( P=0.005). UC patients in the malnourished group had longer hospital stay ( P<0.001), higher hospitalization costs ( P<0.001), and higher rates of drug escalation/conversion therapy, re-admission and surgery at 12 weeks and 54 weeks ( P<0.05). Binary logistic regression analysis showed that a high Mayo score ( OR=3.606, P=0.016), a high modified Mayo score ( OR=1.346, P=0.009) and malnutrition ( OR=1.430, P=0.012) were independent risk factors for adverse clinical outcomes of hospitalized UC patients at 12 weeks. A high modified Mayo score ( OR=6.491, P=0.011) and malnutrition as per GLIM criteria ( OR=6.693, P=0.033) were independent risk factors for adverse clinical outcomes of hospitalized UC patients at 54 weeks. Conclusions:GLIM and ESPEN 2015 diagnostic criteria show high consistency in the diagnosis of malnutrition in hospitalized UC inpatients. Malnutrition may imply adverse clinical outcomes of hospitalized UC patients, which is an independent risk factor for the adverse clinical outcome of hospitalized UC patients.

Objective:To evaluate the prevalence and related risk factors of new onset diabetes after chronic pancreatitis by meta-analysis.Methods:Chronic pancreatitis, diabetes, post pancreatitis diabetes, type 2 diabetes, type 3c diabetes, endocrine dysfunction, chronic pancreatitis, diabetes mellitus, post pancreatitis diabetes mellitus, endocrine efficiency, risk factors were used as keywords, and the network database such as the CNKI database, Wanfang, Weipu, Chinese Medical Journal Full Text, PubMed, Embase, Cochrane Library, Web of Science, and so on from the database establishment to January 2023 were searched. The prospective and retrospective cohort studies on new diabetes after chronic pancreatitis published were searched and retrieved, and the papers were screened and the quality were evaluated according to preset inclusion and exclusion criteria; and the important data were extracted. Review Manager 5.4 was used for meta-analysis.Results:22 papers were finally included, including 13 785 patients with chronic pancreatitis, of which 4 233 were patients with new onset diabetes. Meta-analysis showed that the incidence of new diabetes after chronic pancreatitis was 29% ( RD=0.29, 95% CI 26%-32%, P<0.0001), which increased and tended to be stable along with the disease course. Alcohol drinking, smoking, alcoholic chronic pancreatitis, pancreatic calcification, biliary stricture, male, conservative treatment, pancreatic cyst and older onset age were considered as risk factors for new diabetes after chronic pancreatitis, and endoscopic treatment was considered as protective factors. Conclusions:The incidence of new diabetes after the diagnosis of chronic pancreatitis is relatively high. Clinically, we can identify high-risk groups exposed to risk factors, and early intervention can reduce the incidence rate of new diabetes after chronic pancreatitis and improve the prognosis of patients.

Objective:To investigate the predictive value of systemic immune inflammation index (SII) for the overall survival of patients with pancreatic cancer by propensity score matching analysis.Methods:The clinical data of 457 patients with pancreatic cancer admitted to the Affiliated Hospital of Qingdao University from August 2000 to December 2019 were retrospectively analyzed. The age, gender, presence of jaundice, pancreatitis and diabetes, serum CA19-9, total bilirubin level, neutrophil count, platelet count, lymphocyte count in blood, presence of radical surgery, tumor TNM stage, tumor location and the like were recorded. The cut-off value of SII was determined by Youden index. The patients were divided into high and low SII groups accroding to the cut-off value. The propensity score matching was applied to reduce the selection bias of patients. Patients were 1∶2 matched and the caliper value was 0.1. The difference on overall survival between the two groups was compared. The prognostic factors were analyzed by univariate and multivariate Cox regression analysis. Kaplan-Meier was used to draw the overall survival curve to calculate the cumulative survival rate, and the differences between the curves were analyzed by Log-Rank test.Results:The cut-off value of SII was 765. There were statistically significant differences between the high SII group ( n=125) and the low SII group ( n=332) on the presence or absence of pancreatitis, the level of total bilirubin in blood, radical surgery, and TNM stage before the propensity score matching (all P value <0.05). After propensity score matching, there was no statistically significant difference between the high SII group ( n=113) and the low SII group ( n=182) on all the clinical parameters mentioned above except for CA19-9, indicating that the two groups were comparable. Univariate analysis showed that the level of CA19-9, SII, radical surgery and different TNM stage were all related to the overall survival of pancreatic cancer patients. Multivariate analysis showed that high CA19-9 level, high SII, no radical surgery, and worse TNM stage were independent risk factors for short overall survival, and high SII ( HR=1.882, 95% CI 1.446-2.450, P<0.001) was significantly associated with poor prognosis. The overall survival of patients with high SII was obviously shorter than the low SII group ( P<0.001), and the average survival time of patients with high and low SII were 8.86 and 11.38 months, respectively. Conclusions:SII is of great value in evaluating the overall survival of pancreatic cancer patients. Higher SII is associated with shorter overall survival.

Objective:To investigate the prevalence of malnutrition in hospitalized patients with ulcerative colitis (UC) using the Global Leadership Initiative on Malnutrition (GLIM) criteria, compare the body composition, clinical indicators, and occurrence of poor UC outcomes between the malnutrition group and the non-malnutrition group, and analyze the risk factors of malnutrition.Methods:A total of 104 UC patients hospitalized in the Affiliated Hospital of Qingdao University during 2019 to 2021 and with relevant data collected through UC-sarcopenia Prospective Study were included. Data including nutritional risk screening 2002 (NRS 2002) scores, diagnosis of malnutrition per GLIM criteria, body composition data, clinical data and occurrence of poor outcomes were extracted. All patients were screened for nutritional risk using NRS 2002 at admission, and those at nutritional risk were further evaluated for malnutrition diagnosis per GLIM criteria. The prevalence of malnutrition in UC inpatients, the differences in indicators between malnutrition and non-malnutrition groups, and the risk factors of malnutrition were analyzed.Results:Among the enrolled UC patients , 35 (33.7%) were at nutritional risk, and 30 (28.8%) were diagnosed as malnutrition by GLIM criteria. Compared with the non-malnutrition group, the body composition indexes, including body fat mass, protein, skeletal muscle mass, segmental muscle mass, body water, waist circumference, arm circumference, visceral fat area, basal metabolic rate and body cell mass, all decreased to some extent in the malnutrition group ( P < 0.05). Prealbumin and albumin levels were lower ( P < 0.01). The modified Mayo endoscopic score (MMES), C-reactive protein level and erythrocyte sedimentation rate were higher ( P < 0.01). The rates of re-admission and surgery due to disease activity at 90 days were higher ( P < 0.05). High MMES ( OR =1.534, P = 0.044) and low albumin level ( OR =0.781, P = 0.013) were risk factors for malnutrition in UC patients. Conclusions:GLIM criteria is suitable for the diagnosis of malnutrition in hospitalized UC patients, and malnutrition patients are more likely to experience poor outcomes such as short-term re-admission and surgery. UC patients with higher MMES and lower albumin level are more likely to suffer from malnutrition.

Objective To observe the effect of tiopronin combined with glutathione on the levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), glutamyltransferase (GGT),blood fat and laminin (LN) in patients with non-alcoholic fatty liver. Methods A total of 84 non-alcoholic fatty liver patients admitted to our hospital from March 2018 to September 2019 were selected and randomly divided into control group and observation group, with 42 cases in each group. The control group was treated with tiopronin, and the observation group was treated with glutathione and tiopronin. The levels of ALT, AST, GGT and blood fat were recorded and compared before and after treatment. Results After treatment, the levels of ALT, AST and GGT in the two groups were significantly lower than before treatment (P<0.05). After treatment, the levels of ALT, AST, and GGT in the observation group were different from those in the control group, which was statistically significant (P<0.05). Before treatment, there was no difference in serum TC, TG, and LDL levels between the two groups, which was not statistically significant (P>0.05). The above-mentioned serum levels of the observation group after treatment were lower than those in the control group, and there was a difference, which was statistically significant (P<0.05); the levels of PCⅢ, PCⅣ, and LN in the treatment group after treatment were significantly lower than those of the control group. The difference was statistically significant (P<0.05). Conclusion The application of tiopronin combined with glutathione in the treatment of non-alcoholic fatty liver can promote the recovery of liver function and reduce the concentrations of TC, TG and LDL, which is worthy of clinical promotion.

Objective:To determine the prevalence of Helicobacter pylori (Hp) infection in orthotopic liver transplantation (LT) recipients, and to study the efficacy and safety of Hp eradication therapy.Methods:13C-urea breath test was carried out between July 2018 and October 2019. There were 104 males and 26 females with an average age of 52.1 year for these LT recipients who were regularly followed-up in the Organ Transplant Center, the Affiliated Hospital of Qingdao University. Propensity scoring was used to match age and gender in a ratio of 1∶3. A healthy group of individuals consisting of 299 males and 91 females, with an average age of 51.8 years, were selected as the control group also in a ratio of 1∶3. All patients underwent 13C-urea breath test to evaluate Hp infection and results of quadruple therapy. Results:The prevalence of Hp infection among the LT recipients was 18.5%(24/130) which was significantly lower than the control group 36.4% (142/390) (χ 2=14.400, P<0.001). Among the recipients who received LT and 13C-urea breath test for less than 1 year, 1-3 years and more than 3 years, the prevalences of Hp infection were 14.3% (6/42), 17.8%(8/45) and 23.3%(10/43), respectively. Although the prevalence of Hp showed a gradually increasing trend, no correlation between Hp infection and duration from LT was observed (χ 2=1.321, P=0.517). Seventeen Hp positive recipients underwent Hp eradication therapy. The success rate of Hp eradication was 100.0%(17/17). Immunosuppressant concentration was monitored regularly in 10 patients. During Hp eradication, the blood concentration of immunosuppressant increased from 1.7 to 3.6 times, and the drug dosage was reduced to one half to one third of what it was before Hp eradication. Seven of these 17 recipients suffered from adverse effects caused by increased levels of blood concentration of immunosuppressants, including headache, hypertension, insomnia and irritability. Normal liver and kidney functions were observed during eradication. Conclusion:In this study, the prevalence of Hp infection among liver transplant recipients was 18.5%. The success rate of Hp eradication was 100% using bismuth-containing quadruple therapy. The dosage of immunosuppressant required to be monitored, and if necessary, adjusted during eradication to reduce adverse side effects.

Objective: To evaluate the feasibility of expanded indication for endoscopic submucosal dissection (ESD) in undifferentiated early gastric cancer, to investigate the risk factors of lymph node metastasis (LNM), so as to provide the theoretical evidence for the choice of treatment. Methods: From June 2007 to December 2018, at the Affiliated Hospital of Qingdao University, the clinical and pathological data of 807 patients with undifferentiated early gastric cancer and undergoing gastrectomy plus lymphadenectomy were retrospectively analyzed. Chi-square test was performed to analyze the correlation between clinicopathologic characteristics of early gastric cancer and LNM. Multivariate logistic regression model was used to analyze the independent risk factor of LNM. Results: LNM was found in 17.2% (139/807) patients with undifferentiated early gastric cancer. And no LNM was detected in 110 patients who met the expanded indication of ESD. The results of univariate analysis indicated that LNM was significantly associated with increased carcinoembryonic antigen (CEA), tumour size, gross type, ulcer, invasion depth, lymphovascular invasion and perineural invasion (χ²=4.500, 13.332, 16.611, 6.083, 51.064, 0.564 and 17.006, all P<0.05). The results of multivariate analysis demonstrated that the maximum diameter of tumor over 20 mm (odds ratio (OR)=1.606, 95% confidence interval (CI) 1.021 to 2.526, P=0.040), lymphovascular invasion (OR=16.835, 95%CI 10.510 to 26.966, P<0.01), the depth of submucosal superficial invasion (≤500 μm ; OR=1.962, 95%CI 1.022 to 3.765, P=0.043) and the depth of submucosal deep invasion (>500 μm ; OR=3.014, 95%CI 1.753 to 5.181, P<0.01) were independent risk factors of LNM in early gastric cancer. Conclusions The expanded ESD indication of undifferentiated early gastric cancer is applicable for endoscopic treatment considering the low risk of LNM. In early undifferentiated gastric cancer, maximum diameter of tumor over 20 mm, lymphovascular invasion, submucosal superficial and deep invasion are the independent risk factors of LNM.

Objective To evaluate the clinical application value of serum high sensitive α-fetoprotein variant ratio (hs-AFP-L3％) in the diagnosis and treatment of hepatocellular carcinoma.Methods From October 2016 to March 2018,at Affiliated Hospital of Qingdao University,160 patients diagnosed with hepatocellular carcinoma,32 patients with intrahepatic cholangiocarcinoma (ICC),52 patients with post-hepatitis B liver cirrhosis,53 patients with chronic hepatitis B and 50 healthy controls were enrolled.The serum levels of hs-AFP-L3％ and α-fetoprotein were measured.Mann-Whitney U test,Spearman correlation analysis,Wilcoxon signed rank test and chi-square test were performed for statistical analysis.Results The serum levels of hs-AFP-L3％ and α-fetoprotein in hepatocellular carcinoma group were 24.90％ (4.68％ to 61.85％) and 113.45 μg/L (11.18 μg/L to 1 803.48 μg/L),respectively,which were higher than those in ICC group (0.50％,0.50％ to 0.50％;and 2.79 μg/L,1.72 μg/L to 4.04 μg/L),cirrhosis group (0.50％,0.50％ to 5.25％;and 18.35 μg/L,3.95 μg/L to 31.93 μg/L),chronic hepatitis group (0.50％,0.50％ to 4.25％;and 2.70 μg/L,1.80 μg/L to 17.00 μg/L),and healthy control group (0.50％,0.50％ to 0.50％;and 1.94 μg/L,1.46 μg/L to 2.63 μg/L),and the differences were statistically significant (U =461.00,1 485.50,1 141.00,625.00;401.50,2 207.00,1 254.00,266.00;all P ＜0.01).The sensitivity of hs-AFP-L3％ and α-fetoprotein in the diagnosis of hepatocellular carcinoma was 66.3％ and 70.0％,respectively;and the difference was not statistically significant (x2 =0.54,P ＞ 0.05).The sensitivity of the combined detection was 82.5％,which was higher than that of the separate detection,and the differences were statistically significant (x2 =24.04 and 18.05,both P ＜0.01).The specificity of hs-AFP-L3％ was 95.2％,which was higher than that of α-fetoprotein (68.6％),and the difference was statistically significant (x2 =26.04,P ＜ 0.01).The specificity of the combined detection of these two markers was 68.6％,which was lower than that of hs-AFP-L3％ alone (95.2％),and the difference was statistically significant (x2 =26.04,P ＜ 0.01).There was no statistically significant difference in the specificity between the combined detection and α-fetoprotein detection alone (68.6％,P ＞ 0.05).The sensitivity of hs-AFP-L3％ in the diagnosis of patients with α-fetoprotein-negative (α-fetoprotein ＜ 20 μg/L) hepatocellular carcinoma was 41.7％.The serum levels of hs-AFP-L3％ and α-fetoprotein were both positively correlated with tumor size and clinical stage (hs-AFP-L3％ r =0.272 and 0.436;α-fetoprotein r =0.375 and 0.458;all P ＜ 0.01).The reduction of serum hs-AFP-L3％ in 38 patients with hepatocellular carcinoma after operation was 82.2％,which was higher than that of oα-fetoprotein (69.2％),and the difference was statistically significant (U =532.50,P =0.049).There was no correlation between serum level of hs-AFP-L3％ and α-fetoprotein level (r =0.077,P ＞ 0.05).Conclusions The sensitivity of hs-AFP-L3％ is similar to that of α-fetoprotein in the diagnosis of hepatocellular carcinoma,while the specificity of hs-AFP-L3％ is higher than that of α-fetoprotein.The combined detection of the two markers can improve the diagnostic rate of hepatocellular carcinoma.The hs-AFP-L3％ has a high diagnostic value in α-fetoprotein-negative hepatocellular carcinoma.

Objective To investigate the risk factors of pancreatic pseudocysts(PPC) in patients with acute pancreatitis (AP) in a retrospective cohort study. Methods 460 AP patients with complete follow-up data admitted in Affiliated Hospital of Qingdao University from January 2004 to March 2012 were retrospectively analyzed,who were divided into PPC group and control group. Age,gender,body mass index(BMI),history of diabetes,etiology,the presence of ascites and hydrothorax,the presence of abdominal mass,the presence of acute fluid collection, APACHEⅡ score at 48 h admission, CT severity index (CTSI), serum albumin, amylase,LDH,ALP, BUN, Cr, TG, TB, conjugated bilirubin, CRP, serum calcium and other laboratory markers were recorded. Univariate logistic regression analysis was used to select the factors that were statistically different between two groups, and multivariate logistic regression analysis was performed to determine the independent risk factors for AP complicated with PPC. Results 143(31.1%) of 460 AP patients developed PPC. On univariate analysis, a total of 11 factors including male sex, BMI ≥28 kg/m2, history of diabetes, alcoholic pancreatitis, ascites, pleural effusion, palpable abdominal mass, acute fluid collections,APACHEⅡscore,CTSI≥7 and serum albumin were statistically different between two groups. On multiple logistic regression analysis, it was shown that male sex (OR 3.23, 95% CI 1.560~ 6.301, P=0.03),history of diabetes (OR 2.23,95% CI 1.021~3.920,P=0.04), ascites (OR 1.62,95% CI 0.652~2.432, P=0.01), pleural effusion (OR 2.43, 95% CI 1.201~7.201, P=0.03), a palpable abdominal mass(OR 1.83,95% CI 0.737~4.320,P<0.001) and CTSI≥7(OR 5.12,95% CI 1.890~14.012, P<0.001) were independent risk factors significantly associated with the PPC formation. Conclusions The male sex, diabetic history, ascites, pleural effusion, palpable abdominal mass and high CTSI score were the independent risk factors of PPC formation in AP.

PURPOSE: This study was aimed to investigate the effect of pseudolaric acid B (PAB) on proliferation, invasion and epithelial-to-mesenchymal transition (EMT) in pancreatic cancer cells and to explore the possible mechanism. MATERIALS AND METHODS: The pancreatic cancer cell line SW1990 was cultured and treated with PAB dose- and time-dependent manners. Cell proliferation and invasion ability were measured by MTT assay and Matrigel/Transwell test, respectively. Semi-quantitative real-time polymerase chain reaction and Western blotting were conducted to detect the expression of EMT markers and the key molecules. Finally, nude mice subcutaneous transplantation tumor model was used to confirm the therapy efficacy of PAB. RESULTS: PAB could inhibit SW1990 cell proliferation and invasion in time- and dose-dependent manners. Vimentin, fibronectin, N-cadherin, Snail, Slug, YAP, TEAD1, and Survivin were down-regulated (p < 0.01), while E-cadherin, caspase-9, MST1, and pYAP were up-regulated (p < 0.05). Combined PAB and gemcitabine treatment markedly restricted the tumor growth compared with gencitabin or PAB alone groups. CONCLUSION: PAB could inhibit the proliferation and invasion ability of pancreatic cancer cells through activating Hippo-YAP pathway and inhibiting the process of EMT.
