Crohn 's disease (CD) is an intestinal inflammatory disease of unknown etiology, the pathophysiological mechanism is still unclear. The enteric nervous system (ENS) is responsible for the autonomous regulation of intestinal function. Therefore, ENS dysfunction may be the core of the pathophysiological mechanism of CD. Here, we review the pathophysiological mechanism by which ENS contributes to the development of CD, with a focus on the role of aberrant histological manifestations of ENS and plexitis in predicting the recurrence of CD following surgery.

Objective:To explore the potential profile characteristics of cancer-related worries in patients after surgery for early-stage lung cancer, and the influencing factors of different categories, provide reference for patients to formulate individualized rehabilitation programs and psychological intervention measures.Methods:A cross-sectional survey method was used to conveniently select patients who received outpatient follow-up after lung cancer surgery at Shanghai Pulmonary Hospital Affiliated to Tongji University from October 2022 to October 2023 as the survey subjects. The general information questionnaire, the Chinese version of Brief Cancer-related Worry Inventory, the Chinese version of the MD Anderson Symptom Inventory, Brief Illness Perception Questionnaire, 10-item Connor Davidson Resilience Scale and Medical Coping Modes Questionnaire were examined. Latent profile analysis was performed on the cancer-related worry scores of lung cancer surgery patients, and its influencing factors were explored by binary Logistic regression analysis.Results:A total of 302 patients after lung cancer surgery were included, including 111 males and 191 females, aged 18-83(52.73 ± 13.07) years, and the Chinese version of the Brief Cancer-related Worry Inventory scored 380.00 (130.00, 720.00) points. The cancer-related worry of patients after lung cancer surgery could be divided into two potential profile categories: "high worry type" (138 patients accounted for 45.70%) and "low worry type" (164 patients accounted for 54.30%). Symptom burden ( OR=1.055, 95% CI 1.039-1.072), illness perception ( OR=1.190, 95% CI 1.127-1.256), resilience ( OR=0.933, 95% CI 0.886-0.983), and coping modes of confrontation ( OR=0.857, 95% CI 0.757-0.971) and acceptance-resignation ( OR=1.247, 95% CI 1.050-1.481) were influencing factors for grouping cancer related worry profiles (all P<0.05). Conclusions:There was significant heterogeneity in the level of cancer-related worries among patients after surgery for early-stage lung cancer. It is recommended that medical staff provide targeted continuity care measures based on the characteristics of worries of different categories of patients to improve patients' postoperative mental health and quality of life.

This study aimed to comprehensively examine the association of gallstones, cholecystectomy, and cancer risk. Multivariable logistic regressions were performed to estimate the observational associations of gallstones and cholecystectomy with cancer risk, using data from a nationwide cohort involving 239 799 participants. General and gender-specific two-sample Mendelian randomization (MR) analysis was further conducted to assess the causalities of the observed associations. Observationally, a history of gallstones without cholecystectomy was associated with a high risk of stomach cancer (adjusted odds ratio (aOR)=2.54, 95% confidence interval (CI) 1.50-4.28), liver and bile duct cancer (aOR=2.46, 95% CI 1.17-5.16), kidney cancer (aOR=2.04, 95% CI 1.05-3.94), and bladder cancer (aOR=2.23, 95% CI 1.01-5.13) in the general population, as well as cervical cancer (aOR=1.69, 95% CI 1.12-2.56) in women. Moreover, cholecystectomy was associated with high odds of stomach cancer (aOR=2.41, 95% CI 1.29-4.49), colorectal cancer (aOR=1.83, 95% CI 1.18-2.85), and cancer of liver and bile duct (aOR=2.58, 95% CI 1.11-6.02). MR analysis only supported the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer. This study added evidence to the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer, highlighting the importance of cancer screening in individuals with gallstones.

This study investigates the pharmacokinetics and metabolic characteristics of three marine-derived piericidins as potential drug leads for kidney disease: piericidin A (PA) and its two glycosides (GPAs), glucopiericidin A (GPA) and 13-hydroxyglucopiericidin A (13-OH-GPA). The research aims to facilitate lead selection and optimization for developing a viable preclinical candidate. Rapid absorption of PA and GPAs in mice was observed, characterized by short half-lives and low bioavailability. Glycosides and hydroxyl groups significantly enhanced the absorption rate (13-OH-GPA > GPA > PA). PA and GPAs exhibited metabolic instability in liver microsomes due to Cytochrome P450 enzymes (CYPs) and uridine diphosphoglucuronosyl transferases (UGTs). Glucuronidation emerged as the primary metabolic pathway, with UGT1A7, UGT1A8, UGT1A9, and UGT1A10 demonstrating high elimination rates (30%-70%) for PA and GPAs. This rapid glucuronidation may contribute to the low bioavailability of GPAs. Despite its low bioavailability (2.69%), 13-OH-GPA showed higher kidney distribution (19.8%) compared to PA (10.0%) and GPA (7.3%), suggesting enhanced biological efficacy in kidney diseases. Modifying the C-13 hydroxyl group appears to be a promising approach to improve bioavailability. In conclusion, this study provides valuable metabolic insights for the development and optimization of marine-derived piericidins as potential drug leads for kidney disease.

Objective: To analyze the changing trend and distribution characteristics of hepatitis C virus (HCV) infection among blood donors in Hebei, thereby providing data to support strategy and procedure adjustment for blood collection and supply institutions. Methods: Data from 12 blood stations in Hebei Province from 2012 to 2021 were collected. These data were analyzed to determine trends in anti-HCV antibody double reagent reactive rate and to characterize its distribution among different donor categories, genders and birth cohorts. Results: During the period from 2012 to 2021, a total of 7.4576 million samples were tested at 12 blood stations in Hebei Province, with 3.4659 million (46.47%) from first-time donors, and 3.9917 million (53.53%) from repeat donors. The number (of anti-HCV double reagent reactive samples was 7167 (9.61/10 000). The anti-HCV double reagent reactive rate showed a annual downward trend (P<0.05), from 17.40/10 000 at the beginning to 4.95/10 000 at the end of the study period. Additionally, the double reagent reactive rate of repeat blood donors had remained below 1/10 000 since 2017. The double reagent reactive rate of first-time blood donors (19.42/10 000) was higher than in repeat donors (1.09/10 000) (P<0.05), and the double-reagent reactive rate of female first-time blood donors (20.98/10 000) was higher than that of male first-time blood donors (18.49/10 000) (P<0.05). The anti-HCV double reagent reactive rate among first-time donors exhibited two distinct peaks within the pre-1976 and 1989-1994 birth cohorts, with notable gender differences observed in both peak periods. The rate of double reagent reactive in females born before 1976 (52.22/10 000) was higher than that in males (32.28/10 000) (P<0.05), while that of males born in 1989-1994 was higher (25.75/10 000) than that of females (14.28/10 000) (P<0.05). Conclusion: The prevalenc of HCV infection among blood donors in Hebei Province has shown a consistent year-over-year decline over the study period. The majority of infected individuals are found among the first-time blood donors born before 1995. These trends and characteristics provide valuable insights for developing pre-blood collection screening strategies, analyzing nucleic acid test data in blood screening, adjusting blood screening procedures, and provide evidence for targeted screening of high-risk populations as part of public health initiatives to eliminate hepatitis C.

Objective To investigate the initial dose and safety of intravenous infusion of sodium (s)-2-(dithiocarboxylato((2R,3R,4R,5R,6R)-2,3,4,5,6-pentahydroxyhexyl) amino)-4-(methylthio) butanoate (GMDTC) for the displacement of cadmium. Methodsi) Efficacy test. The New Zealand male rabbits were randomly divided into model group, calcium disodium edetate (EDTA) group and GMDTC low-, medium- and high-dose groups after cadmium poisoning using 2.5 cadmium chloride dihydrate. Rabbits in EDTA group were intravenously injected with EDTA dipotassium at a dose of 93.5 mg/kg body weight, rabbits in the three doses groups were intravenously injected of GMDTC at doses of 12.0, 36.0, and 108.0 mg/kg body weight, respectively. The rabbits in the control group (separate set) and model group were intravenously injected with equal volumes of 0.9% sodium chloride solution, administered for five consecutive days per week for 1, 2, and 4 weeks. ii) Toxicity test. Specific pathogen free SD rats were randomly divided into solvent control group and low-, medium- and high-dose groups. In the acute toxicity test, the rats in the three-dose groups were intravenously injected of GMDTC at doses of 200.0, 800.0 and 3 000.0 mg/kg body weight, respectively. In the long-term toxicity test, the rats in the three-dose groups were intravenously injected GMDTC at doses of 100.0, 500.0 and 2 000.0 mg/kg body weight, respectively, once a day for four consecutive weeks, with a recovery period of four weeks. The rats in the solvent control group were given an equal volume 0.9% sodium chloride solution intravenously at the same time. The maximum tolerated dose (MTD) and no observable adverse effect level (NOAEL) were detected. Resultsi) In the one week treatment experiment, the 24 hours urinary cadmium levels of rabbits in the three doses groups were higher than those in the model group at the same time point (all P<0.05). In the two weeks treatment experiment, the 24 hours urinary cadmium levels of rabbits in medium-dose and high-dose groups at the three time points were higher than those in the model group at the same time point (all P<0.05). In the four weeks treatment experiment, the 24 hours urinary cadmium level on the 19th day of rabbits in the low-dose group was higher than that in the model group at the same time point (P<0.05), and the 24 hours urinary cadmium levels of rabbits in medium- and high-dose groups at the five time points were higher than those in the model group at the same time point (all P<0.05), except for the rabbits of fifth day of the medium-dose group. The kidney cadmium levels of rabbits in the low-dose group after four week of treatment and in the medium- and high-dose groups after one, two, and four weeks of treatment decreased compared with the model group (all P<0.05). No obvious adverse effects were observed during the treatment. ii) The MTD of GMDTC in rats administered intravenously in a single dose was 3 000.0 mg/kg body weight. During the period of intravenous infuseion with GMDTC for four consecutive weeks, the blood drug level reached the peak at the end of the first and last administrations (eight min), and no clinical adverse reactions were observed during this period of time, nor was there any apparent accumulation. The NOAEL for intravenous infusion of GMDTC for four consecutive weeks in rats was 500.0 mg/kg body weight. Conclusion The initial dose of the GMDTC injection in the cadmium poisoning rabbit was 36.0 mg/kg body weight, and the recommended initial dose for human is 480.0 mg/person. Intravenous infusion of GMDTC is characterized by rapid absorption, rapid elimination, and no accumulation.

Objective:To establish a prediction model of risk factors for early Q-T interval prolongation after acute myocardial infarction (AMI), which helps prevent and reduce the occurrence of acute malignant events.Methods:This is a case-control study. A total of 100 patients with Q-T interval prolongation after AMI who received treatment at Heilongjiang Provincial Hospital from January 2018 to December 2022 were included in this study. An additional 100 patients without Q-T interval prolongation after AMI who concurrently received treatment in the same hospital were also included in this study. Two model groups, including model group 1 (with Q-T interval prolongation, n = 50) and model group 2 (without Q-T interval prolongation, n = 50), and two test groups, including test group 1 (with Q-T interval prolongation, n = 50) and test group 2 (without Q-T interval prolongation, n = 50), were designated. Logistic regression analysis was performed to construct a prediction model of risk factors for Q-T interval prolongation. The area under the receiver operating characteristic curve was determined to evaluate the prediction model. The value of the prediction model was validated in the test groups. Results:Multivariate logistic regression showed that female gender ( OR = 2.307, 95% CI: 0.09-0.91, P = 0.041) and heart failure ( OR = 3.087, 95% CI: 1.15-8.27, P = 0.025) were independent risk factors for early Q-T interval prolongation after AMI. The area under the receiver operating characteristic curve of the prediction model was 0.770, with a sensitivity of 84.0%, a specificity of 66.0%, the Jordan index of 0.44, and the corresponding optimal critical value of 0.43. This indicates good fit of the model. Conclusion:Female gender and heart failure are independent risk factors for early Q-T interval prolongation after AMI. The model constructed based on the above-mentioned risk factors fits well and has a high predictive value, which helps reduce the occurrence of early Q-T interval prolongation after AMI.
