ObjectiveTo investigate the therapeutic effect of sitravatinib on carbon tetrachloride （CCl₄）-induced liver fibrosis in mice. MethodsA total of 30 male C57BL/6J mice， aged 8 weeks， were randomly divided into control group， CCl₄ model group， and low- （5 mg/kg）， middle- （10 mg/kg）， and high-dose （20 mg/kg） sitravatinib groups. All mice except those in the control group were given intraperitoneal injection of CCl₄ for 4 consecutive weeks to induce liver fibrosis， and since the first day of modeling， the mice in the low-， middle-， and high-dose sitravatinib groups were given sitravatinib at the corresponding dose by gavage every day. The serum levels of total cholesterol （TC）， triglyceride （TG）， and alanine aminotransferase （ALT） were measured for the mice in each group； hepatic hydroxyproline content was measured； HE staining， Masson staining， and Sirius Red staining were used to observe liver histopathological changes； quantitative real-time PCR and Western blot were used to measure the mRNA and protein expression levels of α-smooth muscle actin （α-SMA） and collagen type I alpha 1 （Col1a1） in liver tissue. The therapeutic effect of sitravatinib was assessed based on the above results. A one-way analysis of variance was used for comparison of continuous data between multiple groups， and the least significant difference t-test was used for further comparison between two groups. ResultsCompared with the control group， the model group had significant increases in the levels of TC， TG， and ALT （all P<0.05）， and there were no significant differences in the levels of TC， TG， and ALT between the model group and the low-， middle-， and high-dose sitravatinib groups （all P>0.05）. Hepatic hydroxyproline content decreased after sitravatinib intervention， with a significant difference between the middle-/high-dose sitravatinib groups and the CCl₄ model group （both P<0.05）. Histopathological staining showed that the sitravatinib treatment groups had a reduction in collagen deposition， along with thinning and fragmentation of fibrous septa， and in the high-dose sitravatinib group， 4 mice had a fibrosis stage of S0—S1 and 2 mice had a fibrosis stage of S2—S3， suggesting a certain degree of alleviation of liver fibrosis degree compared with the CCl₄ model group （mainly S3—S4）. The measurement of related molecules showed that sitravatinib downregulated the mRNA and protein expression levels of α-SMA and Col1a1 （all P<0.05）. ConclusionSitravatinib can effectively alleviate CCl₄-induced liver fibrosis in mice， possibly by inhibiting hepatic stellate cell activation and collagen synthesis.

Recent studies have shown that the physiological homeostasis of oral mucosal cells is regulated by the circadian clock.Dis-ruption or dysfunction of the circadian clock is closely associated with the development of oral squamous cell carcinoma(OSCC).Research based on the circadian clock offers a novel perspective on the pathogenesis and therapeutic strategies for OSCC.However,there is current-ly limited research on this topic,and people generally have insufficient understanding and recognition of the circadian clock.Given the complexity and challenges of circadian clock which is the fourth dimension of medical research,we organize relevant experts based on summarizing the current research results of circadian clock in the pathogenesis and precision diagnosis and treatment of OSCC,combining the scientific principles of the circadian clock's role and their long-term research experience,then summarizes and recommends the con-sensus opinions for the research of circadian clock in the pathogenesis mechanism and precision diagnosis and treatment of human OSCC,with the hope of providing guidance for the basic research and clinical application of circadian clock or circadian rhythm in the pathogene-sis mechanism and precision diagnosis and treatment of oral and maxillofacial squamous cell carcinoma.

Objective:To investigate the impact of evaluating the alcohol intake on all-cause mortality in patients with metabolic-associated fatty liver disease（MAFLD）and metabolic dysfunction and alcohol-related liver disease（MetALD）.Method:The retrospective study included patients aged 20 to 74 years with hepatic steatosis diagnosed by ultrasound，with data from the Third National Health and Nutrition Examination Survey（NHANES III）between 1988 and 1994. Participants were categorized into light，moderate，and heavy drinking groups according to daily alcohol intake. Multivariable-adjusted hazard ratios（aHR）and their 95% confidence intervals（ CI）were calculated by Cox proportional risk regression modeling to assess the effect of alcohol intake on all-cause mortality. Results:A total of 2 322 patients were included in the study. Males accounted for 50.2%（1 166/2 322），with a age of 42.0（31.3，57.0）years，a median follow-up of 316.0（270.0，337.0）months，and an all-cause mortality rate of 1.48% per person-year. There were 1，763 cases in the light drinking group，333 in the moderate drinking group，and 226 in the heavy drinking group.The all-cause mortality rates for patients in the three drinking groups were 1.38%，1.67%，and 2.10% per person-year，respectively. The moderate（a HR=1.37，95% CI：1.12 to 1.67， P=0.002）and heavy（a HR=1.45，95% CI：1.17 to 1.80， P=0.001）drinking groups were independently associated with increased all-cause mortality following covariate adjustment. There was a difference in all-cause mortality for alcohol intake in non-type 2 diabetes mellitus（T2DM）patients under 60 years of age（ P<0.05），but the difference was not statistically significant between non-T2DM patients over 60 years of age and T2DM patients of all ages（ P>0.05）according to the analysis of diabetes status and age subgroups. Conclusion:Alcohol intake has a dose-dependent negative effect on patients with MAFLD and MetALD. The risk of all-cause mortality increased significantly with increasing alcohol intake.

Objective:To analyze the association between standardized management of clinical research, initiated by investigators and guided by clinical research management policies in healthcare institutions, and changes in the research behavior of graduate students.Methods:Theses related to cardiovascular health published by graduate students in the Sichuan-Chongqing region of China between January 2019 and June 2024 were retrieved from the China National Knowledge Infrastructure database. Multilevel models were used to analyze changes in ethical compliance awareness, research methodology standardization, and academic collaboration of graduate students before and after policy implementation.
