Tricellulin, a key tricellular tight junction (TJ) protein, is essential for maintaining the barrier integrity of acinar epithelia against macromolecular passage in salivary glands. This study aims to explore the role and regulatory mechanism of tricellulin in the development of salivary gland hypofunction in Sjögren's syndrome (SS). Employing a multifaceted approach involving patient biopsies, non-obese diabetic (NOD) mice as a SS model, salivary gland acinar cell-specific tricellulin conditional knockout (Tric^CKO) mice, and IFN-γ-stimulated salivary gland epithelial cells, we investigated the role of tricellulin in SS-related hyposalivation. Our data revealed diminished levels of tricellulin in salivary glands of SS patients. Similarly, NOD mice displayed a reduction in tricellulin expression from the onset of the disease, concomitant with hyposecretion and an increase in salivary albumin content. Consistent with these findings, Tric^CKO mice exhibited both hyposecretion and leakage of macromolecular tracers when compared to control animals. Mechanistically, the JAK/STAT1/miR-145 axis was identified as mediating the IFN-γ-induced downregulation of tricellulin. Treatment with AT1001, a TJ sealer, ameliorated epithelial barrier dysfunction, restored tricellulin expression, and consequently alleviated hyposalivation in NOD mice. Importantly, treatment with miR-145 antagomir to specifically recover the expression of tricellulin in NOD mice significantly alleviated hyposalivation and macromolecular leakage. Collectively, we identified that tricellulin deficiency in salivary glands contributed to hyposalivation in SS. Our findings highlight tricellulin as a potential therapeutic target for hyposecretion, particularly in the context of reinforcing epithelial barrier function through preventing leakage of macromolecules in salivary glands.

Objective To investigate the clinical characteristics and prognostic risk factors in elderly patients with acute myeloid leukemia(AML).Methods A retrospective analysis was conducted on the clinical data of 101 elderly AML patients admitted to Affiliated Hospital of Jiaxing University from January 2022 to December 2024.All patients were treated with azacitidine+venetoclax regimen.The clinical characteristics of patients and the risk factors related to prognosis were explored.Results The median follow-up was 14 months.Among the 101 patients,74 achieved complete remission or complete remission with incomplete hematological recovery.The median overall survival(OS)of patients with aged ≥70 years,white blood cell count＞50 × 109/L,TP53 mutation,complex chromosomes,and high-risk European leukemia net(ELN)risk stratification was significantly shortened(P＜0.05).Multivariate analysis showed that age(HR=0.125,95％CI:0.023-0.662,P=0.015),white blood cell count(HR=0.145,95％CI:0.032-0.662,P=0.013),and ELN risk stratification(HR=100.397,95％CI:14.395-700.207,P＜0.001)were all independent influencing factors for OS in elderly AML patients.Conclusion Age,white blood cell count and ELN risk stratification are all independent influencing factors affecting OS in elderly AML patients.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective To explore the value of integrating CT image features and quantitative dual-energy computed tomography(DECT)parameters in predicting cervical lymph nodes metastasis from laryngeal and hypopharyngeal squamous cell carcinoma(LHSCC).Methods The clinical and imaging data of 99 patients with LHSCC confirmed by pathology were retrospectively analyzed.All patients were divided into metastatic group(41 cases)and non-metastatic group(58 cases).The CT image features,including location,size and depth,were analyzed,respectively.The quantitative DECT parameters in the arterial and venous phases including iodine concentration(IC)and normalized iodine concentration(NIC)were measured.The rank sum test or independent-samples t-test were used to compare the difference of CT image features and quantitative DECT parameters between the two groups.The multivariate logistic regression analysis was used to build the models based on CT image features(image feature model)and combination of CT image features and quantitative DECT parameters(combined model).The receiver operating characteristic(ROC)curve was performed to analyze and compare the difference of predictive efficiency between the two groups.Results There were significant differences in tumor location between the non-metastatic group and the metastatic group(χ2=21.736,P<0.001).Size(33.20 mm vs 24.95 mm,P<0.001),depth(21.10 mm vs 13.15 mm,P<0.001)and NIC in the arterial phase(0.18 vs 0.14,P<0.001)in the metastatic group were significantly higher than those in the non-metastatic group.The area under the curve(AUC),sensitivity,specificity,positive predictive value,negative predictive value,accuracy of the combined model were 0.851,75.6%,82.8%,58.5%,87.9%and 75.8%for predicting cervical lymph nodes metastasis.The AUC,sensitivity,specificity,positive predictive value,negative predictive value,accuracy of the image feature model were 0.792,95.1%,56.9%,53.7%,81.0%and 69.7%,respectively.The prediction performance of the combined model was better than that of the image feature model(Z=-2.028,P=0.043).Conclusion Integrating CT image features and quantitative DECT parameters has important value for predicting cervical lymph nodes metastasis from LHSCC.

Objective To explore the risk factors of electrocardiogram abnormalities in patients with primary liver cancer and its value in predicting prognosis. Methods A total of 120 primary liver cancer patients with transcatheter arterial chemoembolization (TACE) were selected as the research objects, and they were divided into abnormal group (n=32) and non-abnormal group (n=88) according to incidence of electrocardiogram abnormalities at 7 days after operation. Baseline data and changes in 24-hour QT interval variability (24-hour QTV), standard deviation of the normal R-R interval from the beginning of atrial depolarization to ventricular depolarization (SDNN), standard deviation of the normal R-R interval for 5 consecutive minutes (SDANN-index), and mean value of the standard deviation of the normal R-R interval for 5 consecutive minutes (SDNN-index) were compared between two groups; a binary Logistic regression model was used to analyze the influencing factors of electrocardiogram abnormalities in patients with primary liver cancer; the receiver operating characteristic (ROC) curve was used to analyze the area under the curve (AUC), sensitivity and specificity of 24 h QTV, SDNN, SDANN-index and SDNN-index in predicting ECG abnormalities in patients with primary liver cancer. Results Of the 120 primary liver cancer patients with TACE treatment, 32 cases had electrocardiogram abnormalities, including 13 cases of sinus tachycardia with T-wave changes, 2 cases of ST-T changes, 4 cases of supraventricular tachycardia, 4 cases of QT interval prolongation, 4 cases of ventricular premature beats, and 5 cases of atrial premature beats. There were no significant differences in gender, age, super-selective hepatic artery catheterization, gelatin sponge embolization, use of chemotherapy drugs, postoperative vomiting, and blood uric acid on the third day after surgery between the abnormal group and the non-abnormal group (P>0.05); there were significant differences in tumor diameter, liver function classification, dosage of iodized oil, postoperative body temperature, and blood potassium on the third day after surgery between the two groups (P < 0.05). Logistic regression model showed that tumor diameter ≥10 cm, grade A of liver function classification, iodized oil dose ≥10 mL, postoperative body temperature ≥38 ℃, and decreases of 24 h QTV, SDNN, SDANN-index and SDNN-index were the independent factors affecting electrocardiogram abnormalities in patients with primary liver cancer (P < 0.05). ROC curve analysis showed that the values of AUC of 24 h QTV, SDNN, SDANN-index, SDNN-index and comprehensive electrocardiogram parameters in predicting electrocardiogram abnormalities in patients with primary liver cancer were 0.682, 0.651, 0.632, 0.752 and 0.786 respectively, with statistically significant differences (P < 0.05). Conclusion Tumor diameter, liver function classification, dose of iodide oil and postoperative body temperature can affect electrocardiogram abnormalities in patients with primary liver cancer, and electrocardiogram monitoring before and after TACE treatment is conducive to timely detection of electrocardiogram abnormalities.
