Objective:To explore the operability of the Chinese version of the All Aspects of Health Literacy Scale (C-AAHLS) and the Brief Health Literacy Screening (BHLS) for assessing the health literacy level of surgical patients.Methods:A total of 202 surgical patients were recruited in an acute care hospital. C-AAHLS and BHLS were used simultaneously to measure the health literacy of patients, and the consistency of their measurement results was compared.Results:The total health literacy scores of 202 surgical patients measured by C-AAHLS and BHLS were respectively (23.16±2.94) and (7.50±3.58), both were at a medium level, and they are consistent in differences in the health literacy levels of different ages, occupations, and educational levels, with statistical significance; the Bland-Altman graph shows that the maximum difference between the measurement results of the two tools is 1.68 <1.824 (average value), the average value of the difference is close to 0, and the results are highly consistent (P < 0.0001).Conclusions:The results of C-AAHLS and BHLS in measuring health literacy are consistent, and clinical medical staff can choose the suitable measurement tool according to the appropriate situation.

Objective:To investigate the influence of glucose regulatory protein 78 (GRP78) on prognosis and tumor cell proliferation of hepatocellular carcinoma.Methods:The experimental study and retrospective cohort study were conducted. Based on hepatocellular carcinoma tissue chip, in vitro culture of Huh7 and Hep3B hepatoma cells and LO2 normal hepatic cell, and combined with immunohistochemical staining, cell transfection, quantitative real-time polymerase chain reaction (qRT-PCR), Western blot detection, cell proliferation experiments, cell clone formation experiments and high-throughput transcription histological analysis, the GRP78 expression in hepatoma cells was analyzed. Huh7 and Hep3B hepatoma cells being transfected with the GRP78 gene-specific shRNA lentiviruses or the negative control shRNA lentivirus were set as the GRP78 gene-specific shRNA lentivirus group and the negative control shRNA lentivirus group respectively. Observation indicators: (1) GRP78 expression in hepatocellular carcinoma tissue and adjacent tissue and its correlation with the clinicopathological characteristics of hepatocellular carcinoma patients; (2) analysis of factors affecting the prognosis of hepatocellular carcinoma patients; (3) effects of inhibiting of GRP78 expression on the proliferation of hepatoma cells; (4) effects of inhibiting of GRP78 expression on the gene and protein expression of p53, p21, CDK2, CDK4, and CDK6 in hepatoma cells; (5) effects of HA15 on the proliferation and the gene and protein expression of p53, p21, CDK2, CDK4, and CDK6 in hepatoma cells. Measurement data of the normal distribution were expressed as Mean± SD, and comparison of groups was conducted using the t test or ANOVA. Repeated measurement data were analyzed using repeated ANOVA. Count data were expressed as absolute numbers, and comparisons between groups was conducted using the chi-square test. COX proportional hazards regression model was used for univariate and multivariate analysis. The Kaplan-Meier method was used to calculate the survival time and draw survival curve, and the Log-rank test was used for generative analysis. Results:(1) GRP78 expression in hepatocellular carcinoma tissue and adjacent tissue and its correlation with the clinicopathological characteristics of hepatocellular carcinoma patients: results of immunohistochemical staining of hepatocellular carcinoma tissue chip showed that GRP78 was low-expressed in 53 cases and high-expressed in 37 cases of the 90 hepatocellular carcinoma tissues. GRP78 was low-expressed in 84 cases and high-expressed in 6 cases of the 90 paracancerous tissues. There was a significant difference in GRP78 expression between hepatocellular carcinoma tissues and paracancerous tissues ( P<0.05).

Biliary fibrosis (BF) is the result of pathological repair of bile tract injury, characterized by thickening and sclerosis of the bile duct wall and progressive stricture of the lumen, which may ultimately lead to serious adverse outcomes such as biliary obstruction, biliary cirrhosis, liver failure, and hepatobiliary malignancies. Current research describes BF as a pathological feature of certain bile tract diseases, lacking a systematic summary of its etiology, pathophysiology, molecular mechanisms, and treatment. BF is a common but easily neglected disease state in biliary system, which may promote the development and progression of hepatobiliary diseases through abnormal repair mechanism after pathological biliary tract injury. Based on the latest research progress from both domestic and international perspectives, the authors review the concept, clinical manifestation, etiology, pathogenesis, and therapeutic strategies of BF to provide a reference for clinical physicians.

Objective To explore the epidemiological characteristics of lung cancer in Quanshan District of Xuzhou cityand analyze the influencing factors, so as to provide theoretical guidance for the prevention and control of lung cancer in Quanshan District of Xuzhou City. Methods A total of 302 patients with lung cancer diagnosed in the Affiliated Hospital of Xuzhou Medical University were selected as case group from January 2019 to December 2023, and 300 healthy persons were selected as control group, a self-designed questionnaire was used to investigate the general and clinical information of the patients, and Logistic regression was used to analyze the risk factors.Results There were a statistically difference in two groups for the smoking index （χ²=40.058，P<0.001)，Chemical occupational environment（χ²=28.153 , P<0.001), weekly exercise mode（χ²=11.021，P=0.004), emphysema score（χ²=142.812，P<0.001). In addition, the CA125 in the case group was (87.11 ± 13.09) U/ml, while the control group was (16.32 ± 5.61) U/ml, with a statistically difference (t=34.581, P<0.001). The logistic regression results showed that smoking index≥20 cigarettes per day (OR=3.448, P=0.021), chemical occupational environment (OR=4.091, P<0.001), emphysema score (OR=1.302, P<0.001) or severe (OR=1.461, P<0.001), and CA125 detection value ≥ 75U/ml (OR>1.6, P<0.001) were independent risk factors for lung cancer, while moderate weekly exercise (OR=0.821, P<0.001) was a protective factor for lung cancer. Conclusion Smoking, high CA125 index, chemical occupational environment, and long-term emphysema are risk factors for the occurrence of lung malignant tumors in Quanshan District of Xuzhou City, screening regularly of CA125 in people who have smoking, emphysema, and being chemical occupational environment should be strengthened, and appropriate health education in proper exerciseshould be provided to prevent and reduce the incidence of lung malignant tumors.

Background::Although overnight fasting is recommended prior to endoscopic retrograde cholangiopancreatography (ERCP), the benefits and safety of high-carbohydrate fluid diet (CFD) intake 2 h before ERCP remain unclear. This study aimed to analyze whether high-CFD intake 2 h before ERCP can be safe and accelerate patients’ recovery.Methods::This prospective, multicenter, randomized controlled trial involved 15 tertiary ERCP centers. A total of 1330 patients were randomized into CFD group ( n = 665) and fasting group ( n = 665). The CFD group received 400 mL of maltodextrin orally 2 h before ERCP, while the control group abstained from food/water overnight (>6 h) before ERCP. All ERCP procedures were performed using deep sedation with intravenous propofol. The investigators were blinded but not the patients. The primary outcomes included postoperative fatigue and abdominal pain score, and the secondary outcomes included complications and changes in metabolic indicators. The outcomes were analyzed according to a modified intention-to-treat principle. Results::The post-ERCP fatigue scores were significantly lower at 4 h (4.1 ± 2.6 vs. 4.8 ± 2.8, t = 4.23, P <0.001) and 20 h (2.4 ± 2.1 vs. 3.4 ± 2.4, t= 7.94, P <0.001) in the CFD group, with least-squares mean differences of 0.48 (95% confidence interval [CI]: 0.26–0.71, P <0.001) and 0.76 (95% CI: 0.57–0.95, P <0.001), respectively. The 4-h pain scores (2.1 ± 1.7 vs. 2.2 ± 1.7, t = 2.60, P = 0.009, with a least-squares mean difference of 0.21 [95% CI: 0.05–0.37]) and positive urine ketone levels (7.7% [39/509] vs. 15.4% [82/533], χ2 = 15.13, P <0.001) were lower in the CFD group. The CFD group had significantly less cholangitis (2.1% [13/634] vs. 4.0% [26/658], χ2 = 3.99, P = 0.046) but not pancreatitis (5.5% [35/634] vs. 6.5% [43/658], χ2 = 0.59, P = 0.444). Subgroup analysis revealed that CFD reduced the incidence of complications in patients with native papilla (odds ratio [OR]: 0.61, 95% CI: 0.39–0.95, P = 0.028) in the multivariable models. Conclusion::Ingesting 400 mL of CFD 2 h before ERCP is safe, with a reduction in post-ERCP fatigue, abdominal pain, and cholangitis during recovery.Trail Registration::ClinicalTrials.gov, No. NCT03075280.
