Objective To elucidate the mechanism by which the BANCR/miR-145-5p axis regulates the AKT-GLUT1/HK2 pathway through downstream targets Reg3A/DMBT1 to facilitate the Warburg effect in gastric cancer. Methods Expression levels of BANCR, miR-145-5p, Reg3A, and DMBT1 were detected by RT-qPCR and Western blot in gastric cancer tissues and cell lines. Dual-luciferase reporter assays confirmed targeted relationships. Glycolytic capacity was assessed via glucose uptake. Immunohistochemistry analyzed molecular expression in 60 paired clinical samples. The prognostic values of key molecules in the BANCR/miR-145-5p-Reg3A/DMBT1 axis were evaluated by Kaplan-Meier survival analysis and Cox proportional hazards regression model. Results BANCR was significantly upregulated, whereas miR-145-5p was downregulated in gastric cancer tissues, correlating with advanced TNM stage, lymph node metastasis, and poor differentiation. Reg3A and DMBT1 were identified as direct targets of miR-145-5p. Knockdown of BANCR or overexpression of miR-145-5p significantly suppressed Reg3A/DMBT1 expression, reduced AKT phosphorylation and GLUT1/HK2 levels, and inhibited glycolysis. Clinical analysis revealed positive correlations between Reg3A/DMBT1 expression and glycolytic markers, with both serving as independent risk factors for poor prognosis. Conclusion The BANCR/miR-145-5p axis activates the AKT pathway by targeting Reg3A/DMBT1, thereby promoting GLUT1/HK2/LDHA-mediated glycolysis and facilitating the Warburg effect in gastric cancer. This regulatory axis represents a potential therapeutic target and prognostic biomarker.

OBJECTIVE To optimize the management model of drugs used in investigator-initiated trial （IIT）. METHODS With benchmarking analysis， based on the practical work experience of a tertiary specialized hospital in the field of IIT drug management in Shanghai， a thorough review was conducted， involving relevant laws， regulations， and academic literature to establish benchmark criteria and the evaluation standards. Starting from the initiation of IIT projects， a detailed comparative analysis of key processes was carried out， such as the receipt， storage， distribution， use and recycling of drugs for trial. The deficiencies in the current management of IIT drugs were reviewed in detail and a series of optimization suggestions were put forward. RESULTS It was found that the authorized records of drug management were missing， the training before project implementation was insufficient， and the records of receipt and acceptance of IIT drugs were incomplete. In light of these existing problems， improvement measures were put forward， including strengthening the training of drug administrators and stipulating that only drug administrators with pharmacist qualifications be eligible to inspect and accept drugs， etc. The related systems were improved， and 17 key points of quality control for the management of IIT drugs were developed. CONCLUSIONS A preliminary IIT drug management system for medical institutions has been established， which helps to improve the institutional X2023076） framework of medical institutions in this field.

Objective To investigate the effect of angiotensinogen (AGT), angiotensin-converting enzyme (ACE) and AngII receptor (ATR) gene polymorphisms combined with climatic factors on the incidence of essential hypertension (EH) in Tibetan population in Gannan area. Methods A follow-up study was conducted to select 671 Tibetan people in Gannan area who were physically examined in April 2019 at the Health Management Center of the Second Hospital of Lanzhou University and agreed to be enrolled as a fixed cohort, and the blood pressure values of the enrolled subjects were measured after 3.5 years of follow-up, and a total of 501 cases were obtained. At the same time, the peripheral blood of all subjects was collected and the polymorphisms of AGT, ACE and ATR genes were detected by gene chip technology, and the possible interactions were analyzed by logistic regression model, fork generation method and multifactor-dimensionality reduction (MDR). Results Sunshine time was a protective factor for the incidence of hypertension in the Tibetan population of Gannan (OR=0.781), while relative humidity (OR=1.182), air pressure (OR=1.338) and temperature (OR=1.449) were the risk factors for the incidence of hypertension. According to the results of partial correlation analysis, temperature had no effect on the incidence of hypertension after controlling air pressure. There was an additive interaction between high air pressure and the polymorphisms of rs699 (OR=1.650, 95%CI: 1.293-2.399, P<0.001) and rs5049 (OR=1.711, 95%CI: 1.337-4.920, P<0.001) genes of AGT gene; there was a multiplicative interaction between relative humidity and rs699 (OR=0.472, 95%CI: 0.120-0.783, P<0.05);there was a multiplicative interactions between the altitude ≥ 3000m and rs699 (OR=1.503, 95%CI: 1.220-3.174, P<0.01), rs5049 (OR=1.673, 95%CI: 1.380-3.961, P<0.001) or rs2148582 (OR=0.519, 95%CI: 0.284-0.716, P<0.05).However, there was no interaction between climatic factors and ACE or ATR gene polymorphisms on the incidence of hypertension. Conclusion Climatic factors and altitude ≥3 000 m are closely related to the incidence of hypertension in the Tibetan population of Gannan area, and the interaction between AGT gene polymorphisms and climatic factors affects the incidence of hypertension in the population of this area.

OBJECTIVES: To investigate the regulatory role of the NLRP3 signaling pathway in hepatocyte pyroptosis in nonalcoholic steatohepatitis (NASH) under hypoxia. METHODS: Twenty-four male C57BL/6 mice were randomized equally into hypoxic control (A), hypoxic NASH model (B), hypoxic NASH+NLRP3 inhibitor (C), and hypoxic NASH+caspase-1 inhibitor (D) groups. In groups B-D, the mice were fed a methionine choline-deficient (MCD) diet under hypoxic conditions (to simulate a 5000 m altitude) for 6 weeks; the mice in groups C and D received intraperitoneal injections of the respective inhibitors every other day. RESULTS: Compared with those in group A, the mice in group B showed significantly elevated serum levels of FBG, TC, TG, ALT and AST, increased liver lipid content, inflammatory cell infiltration and collagen fiber deposition, and enhanced hepatic expressions of NLRP3, caspase-1, IL-1β and GSDMD proteins, with obvious swelling, cristae breakage, vacuolization, and outer membrane disruption of the mitochondria, ribosome loss in the cytoplasm, destruction of the nuclear membrane, and pathological changes of the rough endoplasmic reticulum. Treatment with NLRP3 inhibitor and caspase-1 inhibitor both significantly lowered serum levels of TC, TG, ALT and AST (but without significantly affecting FBG) in the mouse models, and reduced liver lipid content, inflammatory cell infiltration, collagen deposition, and expression levels of NLRP3, caspase-1, GSDMD and IL-1β. The treatments also significantly improved pathological changes in the mitochondria, ribosomes and endoplasmic reticulum in liver tissues of the mice. CONCLUSIONS NLRP3 signaling pathway plays a key role in promoting hepatocyte pyroptosis in NASH mice under hypoxic condition, and inhibiting this pathway can effectively reduce liver inflammation, suggesting its potential as a therapeutic target for NASH treatment.

ObjectiveTo develop a patient-reported traditional Chinese medicine kidney deficiency pattern (TCM-KDP) scale for colorectal cancer (CRC) patients and evaluate its reliability and validity.MethodsWe administered the TCM-KDP questionnaire to postoperative patients with stage II and III CRC as part of a multicenter randomized controlled trial (RCT) conducted in China from December 2018 to September 2021. The TCM-KDP scale consists of eight items on patient-reported symptoms and is scored on a five-point Likert scale. The scale’s reliability was assessed using Cronbach’s α and test-retest reliability, while content validity was evaluated with the content validity index. We compared the differences in serum cytokine levels and other clinical factors between patients with higher and lower KDP scores.ResultsOf the 378 patients analyzed in the original RCT, 352 (93.2%) completed the TCM-KDP questionnaire. The Cronbach’s α of the eight-item TCM-KDP scale was 0.734, and the test-retest reliability was 0.745. Our exploratory factor analysis yielded eight factors that explained the variance of 50.34%. The mean TCM-KDP score was 2.80 ± 0.92. Compared with patients with stage II CRC, those with stage III CRC had significantly higher TCM-KDP scores (2.25 vs. 2.50, P = .026). We categorized all patients into high- or low-KDP score groups (the cut-off score was 2.8). Patients with lower TCM-KDP scores had significantly higher serum interleukin-1β expression levels (P = .04).ConclusionThe patient-reported TCM-KDP scale demonstrated relatively good feasibility, internal consistency, and test-retest reliability among patients with CRC. Future studies could apply this scale to other cancer types and diseases.

Objective To evaluate the regulatory effects of psilocybin on social behavior of male C57BL/6J mice.Methods Adult male C57BL/6J mice were intraperitoneally injected with psilocybin(0.2,1 and 5 mg/kg,i.p.),and the effects of psilocybin on prosocial behavior were evaluated by the three-chamber test.Stressed mice undergoing chronic social defeat stress(CSDS)were given acute intraperitoneal injection of psilocybin(1 mg/kg)to evaluate the moderation of social novelty preference behavior using the modified two-chamber test.Results Intraperitoneal injection of psilocybin(1 mg/kg)promoted prosocial behavior and prolonged social time(P＜0.01),while intraperitoneal injection of psilocybin(0.2 mg/kg)had no apparent effect on the prosocial behavior of mice,and intraperitoneal injection of psilocybin(5 mg/kg)inhibited prosocial behavior before promoting it.Further studies showed that intraperitoneal injection of psilocybin(1 mg/kg)increased the social novelty exploration time in stressed mice undergoing CSDS.Conclusion This study shows that 1 mg/kg dose of psilocybin can promote the prosocial behavior in mice,and potentially ameliorate the deficit of social novelty preference behavior in CSDS mice.
