Objective: To explore the relationship between beverage dependence and sleep quality among college students, providing empirical evidence for improving their sleep quality. Methods: From December 2024 to January 2025, a convenience sampling method was used to conduct a questionnaire survey among 3 974 college students from four universities in Anhui Province. The Beverage Addiction Scale for College Students (BASCS) was used to assess beverage dependence, and the Self rating Scale of Sleep(SRSS) was used to evaluate sleep quality. A multivariate Logistic regression model was employed to analyze the relationship between beverage dependence and sleep quality, and a restricted cubic spline model was used to examine the dose response relationship between the two. Results: The positive rate of beverage dependence symptoms among college students was 7.6%, with positive rates of 9.6%, 13.8%, and 7.4% for the withdrawal symptoms, health effects, and dependence symptoms dimensions, respectively. The detection rate of sleep disorders was 23.6%. Multivariate Logistic regression analysis showed that after adjusting for covariates such as grade, gender, and body mass index, compared with the no beverage dependence group, students with positive beverage dependence symptoms had a higher risk of sleep disorders( OR =3.71, 95% CI =2.87-4.80, P <0.01). The OR (95% CI ) for sleep disorders among students with positive symptoms in the withdrawal symptoms, health effects, and dependence symptoms dimensions were 2.80(2.22-3.53), 2.38(1.95-2.91), and 2.45(1.89-3.18)(all P <0.01). Further analysis using a restricted cubic spline model revealed that the overall beverage dependence score and its three dimensional scores were approximately linearly related to the risk of sleep disorders among college students (all nonlinear P >0.05). Conclusions Beverage dependence is associated with sleep quality among college students. Schools should take multiple approaches, such as health education on beverage awareness, to improve students sleep quality.

Objective To explore the impact of severe weather on road traffic injuries (RTIs). Methods Relevant literature on the impact of meteorology on the occurrence and resulting casualties of road traffic injuries was searched. Meta-analysis was performed on the included literature using state16.0 software. Results A total of 28 articles were included. The results of meta-analysis showed that heat wave, cloudy day, snowy day, rainy day and other severe weather such as storm had a statistically significant impact on the occurrence of road traffic injuries. Severe weather such as storms had a statistically significant impact on RTIs casualties. Conclusion Heat wave, cloudy day, snowy day, rainy day, storm and other bad weather are independent risk factors for the occurrence of RTIs. Storm is a risk factor for accident casualties. There is not enough evidence to show that low temperature, cold wave and heavy fog are the influencing factors of road traffic accidents.

Liver regeneration following injury aids the restoration of liver mass and the recovery of liver function. In the present study we investigated the contribution of megakaryocytic leukemia 1 (MKL1), a transcriptional modulator, to liver regeneration. We report that both MKL1 expression and its nuclear translocation correlated with hepatocyte proliferation in cell and animal models of liver regeneration and in liver failure patients. Mice with MKL1 deletion exhibited defective regenerative response in the liver. Transcriptomic analysis revealed that MKL1 interacted with E2F1 to program pro-regenerative transcription. MAPKAPK2 mediated phosphorylation primed MKL1 for its interaction with E2F1. Of interest, phospholipase d2 promoted MKL1 nuclear accumulation and liver regeneration by catalyzing production of phosphatidic acid (PA). PA administration stimulated hepatocyte proliferation and enhanced survival in a MKL1-dependent manner in a pre-clinical model of liver failure. Finally, PA levels was detected to be positively correlated with expression of pro-regenerative genes and inversely correlated with liver injury in liver failure patients. In conclusion, our data reveal a novel mechanism whereby MKL1 contributes to liver regeneration. Screening for small-molecule compounds boosting MKL1 activity may be considered as a reasonable approach to treat acute liver failure.

Objective Studies on the expression and location of zinc finger protein A20 (A20) and connective tissue growth factor (CTGF) in liver tissues of patients with chronic hepatitis B were conducted, and the relationship between them and liver fibrosis was determined by FibroScan. Methods Studies on A20 and CTGF in liver tissues of 160 patients with chronic hepatitis B were conducted in accordance with the stage of pathological fibrosis and inflammation of the liver, and quantitative immunohistochemistry test was conducted, and statistical analysis was conducted by FibroScan. Results The expressions of A20 and CTGF in liver tissues increased with the aggravation of liver pathological fibrosis and inflammation, and there were significant differences between each stage and the control group (P<0.05), and there were significant differences between adjacent groups (P<0.05). Studies have shown that FibroScan increases along with pathological fibrosis and inflammation in the liver. There are significant differences between the stage and the control group (P<0.05), and no significant differences between the adjacent groups (P>0.05). There was positive correlation between liver A20 and CTGF, r=0.796 (P<0.05). Conclusions In patients with chronic hepatitis B, A20, CTGF and FibroScan are positively correlated with the degree of liver fibrosis, and A20 and CTGF are also positively correlated with the degree of liver inflammation, which can be used as indicators to evaluate the degree of liver inflammation and fibrosis, and further guide the anti-inflammatory and anti-fibrosis treatment of patients.

Objective To evaluate the change of cardiac structure and function in patients with hypertrophic obstructive cardiomyopathy(HOCM)after ultrasound-guided percutaneous intramyocardial septal radiofrequency ablation(PIMSRA)via cardiac magnetic resonance(CMR).Methods Patients with HOCM who underwent PIMSRA,echocardiography and CMR preoperative scanning and one year after surgery were analyzed retrospectively.Myocardial structural and functional parameters were measured by Circle cardiovascular imaging post-processing software.The changes of myocardial parameters before and after surgery were compared by using paired sample t-test and Chi-square test.Results Compared with the preoperative assessment,patients'clinical symptoms and the cardiac function were significantly improved one year after surgery.The left ventricular outflow tract pressure gradient(LVOT-PG)was significantly decreased and length of mitral regurgitation was shortened one year after surgery compared with before surgery via ultrasound(P<0.05).Compared with the preoperative assessment,CMR showed that patients with end-systolic volume of left atrium,minimum volume of left atrium,transverse diameter of left atrium,thickness of ventricular septum and free wall of left ventricular at end-systolic section were significantly reduced,and left ventricular mass(LVM)was significantly decreased one year after surgery,with statistical significance between before and after surgery(P<0.001).One year after surgery,the left atrium ejection fraction(LAEF)was significantly increased(P<0.05),the maximum slope and the maximum signal intensity of the ventricular septum and the left ventricular free wall of the papillary muscle were significantly increased(P<0.001),and the peak time was significantly decreased(P<0.001)compared with before surgery.Conclusion After PIMSRA treatment,the systolic function of left atrium in HOCM patients is improved,and the microcirculation perfusion of left ventricular is significantly improved.

Tripterygium wilfordii is widely used in the treatment of immune system disease and has a remarkable curative effect. Triptolide and Tripterygium glycosides are the most commonly used active ingredients in clinical practice， but their treatment window is narrow and there are many side effects. The damage involves the reproductive system， blood system， cardiovascular system， digestive system， etc. Based on clinical observations and literature summaries， the symptoms of adverse reactions mostly occur in the digestive system （liver and gastrointestinal tract）. Relevant scholars have launched a lot of studies of the manifestations of liver injury induced by T. wilfordii and the mechanism of liver injury. The mechanism is mainly related to liver cell apoptosis， induction of oxidative stress， immune injury， excessive autophagy of liver cells， abnormal fatty acid metabolism， and abnormal enzyme metabolism in liver tissues. This article reviewed and summarized relevant literature on gastrointestinal injury caused by T. wilfordii， but there are few studies on the manifestations and mechanisms of adverse reactions， which still need further research by scholars. In addition， this article also summarized the research on how to reduce toxicity and enhance efficacy of prescriptions prepared from T. wilfordii in the digestive system， mainly involving compatibility with western medicines （Methotrexate， Leflunomide， Iguratimod， etc.）， use along or combination with Chinese medicines （single Chinese medicine， Chinese medicine monomers， and Chinese medicine compounds）， acupuncture and moxibustion （electroacupuncture and moxibustion）， dosage form improvement （glycol plastid gel， self-dissolving microneedle， solid lipid nanoparticles， gastric floating sustained-release capsules， etc.）， processing （steaming， stir-frying， radish seed processing， money grass processing， licorice processing， etc.）， and other methods to reduce toxicity. To sum up， this article analyzed the manifestations， mechanisms， and methods of reducing toxicity and enhancing efficacy of T. wilfordii-induced liver injury and gastrointestinal injury by sorting out relevant literature， in order to provide a reference for the clinical application of T. wilfordii and some research ideas for the future in-depth study of T. wilfordii-induced digestive system injury.

ObjectiveTo observe the mechanism of chronic psychological stress aggravating idiopathic pulmonary fibrosis （IPF） in rats and the regulatory effect of Xiaoyaosan. MethodSixty SD rats were acclimatized for one week and then randomly divided into five groups： sham operation group， IPF group， IPF and depression model group， pirfenidone group， and pirfenidone + Xiaoyaosan group， with 12 rats in each group. The IPF group was induced by intratracheal instillation of bleomycin （5 mg·kg^-1） and administered 0.9% sodium chloride solution intragastrically. The model group was induced with bleomycin （5 mg·kg^-1） combined with chronic unpredictable mild stress to establish a rat model of IPF and depression and administered 0.9% sodium chloride solution intragastrically. Concurrently， the pirfenidone group was administered pirfenidone aqueous solution （50 mg·kg^-1） intragastrically， and the pirfenidone + Xiaoyaosan group was administered pirfenidone aqueous solution （50 mg·kg^-1） and Xiaoyaosan decoction （19.27 g·kg^-1） intragastrically. The experiment lasted for four weeks. Various parameters， including body weight， food intake， sucrose consumption rate， open field behavior， lung function， lung coefficient， pathological changes in lung tissue， and hydroxyproline （HYP） content were compared among the groups. Enzyme-linked immunosorbent assay （ELISA） was used to measure serum cortisol （CORT）， corticotropin-releasing hormone （CRH）， adrenocorticotropic hormone （ACTH） levels， and serotonin （5-HT） levels in serum and hippocampus. The levels of interleukin-1β （IL-1β）， interleukin-6 （IL-6）， and tumor necrosis factor-α （TNF-α） in serum and lung tissue were also measured. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was employed to determine the mRNA expression of IL-1β， TNF-α， IL-6， p38 mitogen-activated protein kinase （p38 MAPK）， and nuclear transcription factor-κB p65 （NF-κB p65） in lung tissue. Western blot was used to detect the expression of proteins related to the p38 MAPK/NF-κB signaling pathway. ResultCompared with the normal group， IPF and depression model group showed slow weight gain， reduced food intake， decreased sucrose consumption rate， reduced total distance and average speed of movement in the open field test， weakened lung function， increased lung coefficient （P<0.01）， significant inflammatory cell infiltration in lung tissue by hematoxylin-eosin （HE） staining， collagen fiber deposition by Masson staining， and increased HYP content （P<0.01）. There were elevated levels of serum CORT， CRH， and ACTH （P<0.05， P<0.01）， increased protein and mRNA levels of IL-1β， IL-6， and TNF-α in serum and lung tissue， decreased 5-HT levels in serum and hippocampus， and increased relative expression of p-p38 MAPK and p-NF-κB p65 proteins in lung tissue （P<0.01）. Compared with the IPF and depression model group， the depression and IPF of rats in the pirfenidone + Xiaoyaosan group were effectively ameliorated， as evidenced by faster weight gain， increased food intake and sucrose consumption rate， increased total distance and average speed of movement in the open field test， enhanced lung function， reduced lung coefficient （P<0.01）， decreased inflammatory cell infiltration by HE staining， reduced collagen fiber deposition by Masson staining in lung tissue， and decreased HYP content （P<0.01）. Decreased serum CORT， CRH， and ACTH levels （P<0.05， P<0.01）， decreased protein and mRNA levels of IL-1β， IL-6， and TNF-α in serum and lung tissue （P<0.05， P<0.01）， increased 5-HT levels in serum and hippocampus （P<0.05， P<0.01）， and decreased relative expression of p-p38 MAPK and p-NF-κB p65 proteins in lung tissue were also noted （P<0.05， P<0.01）， with the effects of Xiaoyaosan + pirfenidone being more significant. ConclusionChronic unpredictable stress exacerbates the progression of IPF in rats. The combination of Xiaoyaosan and pirfenidone not only improves depressive-like behavior but also alleviates pulmonary fibrosis， potentially through the regulation of the p38 MAPK/NF-κB signaling pathway and inhibition of excessive expression of inflammatory factors.

Objective To improve the efficiency of induced differentiation of primitive neural epithelial cells derived from human induced pluripotent stem cells(hiPSCs-NECs)into functional midbrain dopaminergic progenitor cells(DAPs).Methods HiPSCs were cultured in mTeSRTM medium containing DMH1(10 μmol/L),SB431542(10 μmol/L),SHH(200 ng/mL),FGF8(100 ng/mL),purmorphamine(2 μmol/L),CHIR99021(3 μmol/L),and N2(1%)for 12 days to induce their differentiation into primitive neuroepithelial cells(NECs).The hiPSCs-NECs were digested with collagenase IV and then cultured in neurobasal medium supplemented with 1%N2,2%B27-A,BDNF(10 ng/mL),GDNF(10 ng/mL),AA,TGF-β,cAMP,and 1%GlutaMax in the presence of different concentrations of Rho kinase inhibitor Y27632,and the culture medium was changed the next day to remove Y27632.Continuous induction was performed until day 28 to obtain DAPs.Results Human iPSCs expressed the pluripotency markers OCT4,SOX2,Nanog,and SSEA1 and were positive for alkaline phosphatase staining.The hiPSCs-NECs were obtained on day 13 in the form of neural rosettes expressing neuroepithelial markers SOX2,nestin,and PAX6.In digested hiPSCs-NECs,the addition of 5 μmol/L Y27632 significantly promoted survival of the adherent cells,increased cell viability and the proportion of S-phase cells(P<0.01),and reduced the rate of apoptotic cells(P<0.05).On day 28 of induction,the obtained cells highly expressed the specific markers of DAPS(TH,FOXA2,NURR1,and Tuj1).Conclusion Treatment with Y27632(5 μmol/L)for 24 h significantly promotes the survival of human iPSCs-NECs during their differentiation into DPAs without affecting the cell differentiation,which indirectly enhances the efficiency of cell differentiation.

The correlation between the expression of A20 and BFGF in liver tissue and the stage of hepatic fibrosis and inflammation were analyzed.Results:The expression of A20 in the S1 - S4 phase was higher than that in the S0 phase: (6.12 ± 1.22)%, (10.18 ± 2.43)%, (16.94 ± 5.06)%, (25.99 ± 7.57)% vs. (0.81 ± 0.29)%; the expression of BFGF in the S1 - S4 phase was higher than that in the S0 phase: (6.12 ± 1.22)%, (10.18 ± 2.43)%, (16.94 ± 5.06)%, (25.99 ± 7.57)% vs. (0.81 ± 0.29)%, there were statistical differences ( P<0.05). The expression of A20 in the G1 - G4 phase was higher than that in the G0 phase: (6.56 ± 1.87)%, (10.01 ± 3.29)%, (15.54 ± 5.01)%, (25.86 ± 8.02)% vs. (0.85 ± 0.71)%; the expression of BFGF in the G1 - G4 phase was higher than that in the G0 phase: (5.91 ± 1.52)%, (9.65 ± 2.48)%, (15.03 ± 4.86)%, (24.62 ± 7.22)% vs. (0.79 ± 0.41)%, there were statistical differences ( P<0.05). The results of Pearson test showed that there was a positive correlation between liver A20 and BFGF ( r = 0.824, P<0.05). Conclusions:The expressions of A20 and BFGF in liver tissue increase with the aggravation of liver pathological fibrosis and inflammation, which can be used as important indicators to evaluate the severity of liver fibrosis.
