Objective: To explore the effects of personality and sleep quality with psychological distress of junior and senior high school stduents, so as to provide a reference basis for precise interventions of junior and senior high school students mental health. Methods: In October 2023, a convenience sampling method was used to select 9 034 students aged 12-17 from Shiyan City as the study subjects. The Pittsburgh Sleep Quality Index (PSQI) and Kessler Psychological Distress Scale (K10) were used to collect information on sleep quality and psychological distress of junior and senior high school stduents. Between group comparison was conducted by using t-test and Chi-square test. Generalized linear models were employed to analyze the interaction and joint effects of personality and sleep quality on psychological distress. Results: The generalized linear model analysis showed that the interaction between personality and sleep quality on psychological distress was statistically significant of junior and senior high school students(effect size=0.80, P <0.01). The general linear model analysis indicated that, after adjusting for variables such as age, gender, screen time, and daily sitting time with the extroverted and good sleep quality group as the reference, the introverted and poor sleep quality group had the largest mean difference in psychological distress scores (difference=0.51, P <0.05). When stratified by sleep quality, psychological distress scores were higher in the introverted and neutral personality groups with both poor and good sleep quality compared to the extroverted group (poor sleep quality: introverted difference=3.71, neutral difference=1.14; good sleep quality: introverted difference=2.23, neutral difference=0.57, all P < 0.05). When stratified by personality, psychological distress scores were higher in the poor sleep quality groups for introverted, neutral, and extroverted individuals compared to their good sleep quality counterparts (differences=8.66, 7.83, 7.34, all P < 0.05 ). Conclusions Personality and sleep quality have interactive and joint effects on psychological distress of junior and senior high school stduents. Personalized psychological interventions should be developed based on personality and sleep quality.

The host-microbe co-metabolism system, generating diverse exogenous and endogenous bioactive molecules that influence the host's immune and metabolic functions, plays a crucial role in the pathogenesis of atherosclerosis. Recent studies have elucidated the interaction between natural medicines and this co-metabolism system. Upon oral administration, natural medicine ingredients can undergo transformation by gut microbiota, potentially enhancing their bioavailability or anti-atherogenic efficacy. Furthermore, natural medicines can exert anti-atherogenic effects via modulation of endogenous host-microbe co-metabolism. This review presents an updated understanding of the dual association between natural medicines and host-microbe co-metabolites. It explores the critical function of microbial exogenous metabolites derived from natural medicines and uncovers the mechanisms underlying natural medicines' intervention on key nodes of endogenous host-microbe co-metabolism. These insights may offer new perspectives for cardiovascular disease (CVD) treatment and guide future drug discovery efforts.

Objective To investigate the therapeutic effects and mechanisms of Xuefu Zhuyu Mixture(XFZY)in rats with coronary heart disease(CHD).Methods A CHD rat model was established.Successfully modeled rats were randomly divided into five groups(n=12 each):model group,Lipitor group,low-dose XFZY group(7.02 g·kg-1·d-1),high-dose XFZY group(14.04 g·kg-1·d-1),and high-dose XFZY+RS09[Toll-like receptor 4(TLR4)agonist]group(14.04 g·kg-1·d-1 XFZY+intraperitoneal RS09),with an additional normal control group(n=12).After treatment,following treatment completion,all rats underwent echocardiography to assess left ventricular end-diastolic diameter(LVDd),end-systolic diameter(LVDs),ejection fraction(LVEF),and fractional shortening(FS).Myocardial histopathology and vascular remodeling indices were evaluated via hematoxylin-eosin(HE)staining,while myocardial fibrosis was examined using Masson's trichrome staining.Enzyme-linked immunosorbent assay(ELISA)was employed to quantify inflammatory cytokine levels[tumor necrosis factorα(TNF-α),interleukin(IL)-1β,and IL-6]in myocardial tissues.Immunohistochemical analysis determined protein expression of B-cell lymphoma-2(Bc12)and Caspase 3 in myocardial tissues.Western Blot was performed to measure myocardial protein expression levels of TLR4,phosphatidylinositol 3-kinase(PI3K),phosphorylated protein kinase B(p-AKT),total AKT,phosphorylated mammalian target of rapamycin(p-mTOR),and total mTOR.Results Compared with the normal group,rats in the model group exhibited severe myocardial tissue damage,along with significantly elevated collagen volume fraction,LVDs,LVDd,myocardial levels of IL-6,TNF-α and IL-1β,cardiomyocyte apoptosis ratio,aortic media thickness,and protein expression of Caspase 3,TLR4,PI3K,p-AKT/AKT and p-mTOR/mTOR in myocardial tissue(P＜0.05).Conversely,LVEF,FS,aortic luminal diameter,and Bcl-2 protein content were significantly reduced,the difference being statistically significant(P＜0.05).Compared to the model group,both low-and high-dose XFZY groups as well as the Lipitor group demonstrated attenuated myocardial lesions,with significant reductions in collagen volume fraction,LVDs,LVDd,myocardial IL-6,TNF-α,IL-1β levels,cardiomyocyte apoptosis ratio,aortic media thickness,and protein expression of Caspase 3,TLR4,PI3K,p-AKT/AKT and p-mTOR/mTOR(P＜0.05).Concurrently,LVEF,FS,aortic luminal diameter,and Bcl-2 protein content were significantly increased,the difference being statistically significant(P＜0.05).No statistically significant differences were observed between the high-dose XFZY group and the Lipitor group for any aforementioned parameters(P＞0.05).However,rats treated with high-dose XFZY plus RS09 showed aggravated myocardial injury with manifested interstitial fibrosis,alongside significantly intensified inflammatory response,cardiomyocyte apoptosis,and vascular remodeling compared to the high-dose XFZY alone group(all P＜0.05).Conclusion XFZY alleviates CHD symptoms by suppressing TLR4/PI3K/AKT/mTOR pathway activation,thereby reducing myocardial inflammation,fibrosis,apoptosis,and vascular remodeling.

Objective To investigate the relationship between the levels of peripheral blood iri-sin,myostatin(MSTN),and 25-hydroxyvitamin D[25(OH)D]and the risk and predictive value of sarcopenia in elderly patients with type 2 diabetes mellitus(T2DM)complicated by heart failure.Methods Elderly patients with T2DM complicated by heart failure who visited Xingtai Central Hospi-tal from March 2023 to March 2024 were selected as the study subjects.The sample size was calculated based on the effect size.Patients were divided into modeling set(n=140)and validation set(n=60)at a ratio of 7 to 3 using a simple randomization method.Additionally,according to the occur-rence of sarcopenia,patients in the modeling set were divided into sarcopenia group and non-sar-copenia group.Clinical data and the levels of peripheral blood irisin,MSTN,and 25(OH)D were compared between the modeling and validation sets.The receiver operating characteristic(ROC)curve was used to analyze the predictive efficacy of peripheral blood irisin,MSTN,and 25(OH)D for sarcopenia.Multivariate logistic regression analysis was employed to identify the influencing fac-tors of sarcopenia in elderly patients with T2DM complicated by heart failure,and a relevant predic-tive model was constructed using R software.Results Among 200 elderly patients with T2DM com-plicated by heart failure,71 cases developed sarcopenia,with an incidence rate of 35.50％.The proportion of regular exercise,bone mineral content,and the levels of irisin and 25(OH)D in the sarcopenia group were lower than those in the non-sarcopenia group,while the MSTN level was high-er in the sarcopenia group,and the differences were statistically significant(P＜0.05).The areas under the curve(AUCs)for predicting sarcopenia by irisin,MSTN,and 25(OH)D were 0.878(95％CI,0.812 to 0.927),0.848(95％CI,0.778 to 0.903),and 0.826(95％CI,0.753 to 0.885),respectively.The sensitivities were 74.16％,79.78％,and 88.76％,and the specifici-ties were 74.16％,79.79％,and 88.76％,respectively.The results of multivariate logistic regres-sion analysis showed that lack of exercise habits(OR=2.489,95％CI,1.665 to 3.735),de-creased bone mineral content(OR=2.340,95％CI,1.596 to 3.595),irisin ≤105.44 ng/mL(OR=3.111,95％CI,2.004 to5.147),MSTN＞19.06 μg/L(OR=2.667,95％CI,2.015 to 4.693),and25(OH)D ≤12.23 ng/mL(OR=2.547,95％CI,1.285 to 4.492)were all inde-pendent risk factors for sarcopenia in these patients(P＜0.05).The results of ROC curve analysis showed that the AUCs of the nomogram model for predicting postoperative recurrence in the modeling and validation sets were 0.875 and 0.853,respectively.The Hosmer-Lemeshow test for the model-ing and validation sets showed the following results:x2=0.715,P=0.510;x2=0.651,P=0.568.The calibration curves were basically consistent with the standard curves.The threshold probability range of decision curve analysis(DCA)was 0.1 to 0.9.Within this range,both the modeling and validation sets showed good clinical net benefits.Conclusion Peripheral blood iri-sin,MSTN,and 25(OH)D all have certain predictive values for the occurrence of sarcopenia in elderly patients with T2DM complicated by heart failure.The nomogram model constructed based on irisin,MSTN,and 25(OH)D can provide a quantitative basis for the early screening of sarcopenia in these patients.

【Objective】 To explore the expression of PCDH9 loss in regulating cell cycle and promoting tumor progression. 【Methods】 The clinical records of 127 cases of prostate cancer treated during 2018 and 2023 were collected, including 87 paraffin tissue samples from the G4-5 group and 40 from the G1-3 group. The expressions of PCDH9, p53, Rb and STAT3 were detected with immunohistochemical staining, and the relationship between their expressions and clinicopathological characteristics was analyzed. 【Results】 The expression deletion rate of PCDH9 in prostate cancer tissues in G4-5 group (44.8% vs.7.5%) was significantly higher than that in G1-3 group (P<0.001). The positive expression rates of p53 and STAT3 were 34.5% and 89.7%, respectively, and the expression loss rate of Rb was 27.6% in G4-5 group. The expression loss rates of PCDH9 and Rb were associated with neuroendocrine-like histological morphology, nerve invasion and vascular invasion (P<0.05). In G4-5 group of prostate cancer, PCDH9 expression was positively correlated with the expressions of p53 (r=0.345, P<0.05), Rb (r=0.503, P<0.05) and STAT3 (r=0.224, P<0.05). 【Conclusion】 PCDH9 is prone to loss of expression in high-group prostate cancer tissues, especially in cases with neuroendocrine-like histological morphology, which may regulate the cell cycle through the STAT3 signaling pathway, thereby promoting tumor progression.

Objective:To explore the surgical intervention strategy for metastatic cervical lymph nodes surrounding the carotid artery in head and neck squamous cell carcinoma.Methods:A total of 62 patients with advanced head and neck tumors and carotid wrap by disease treated in Department of Otorhinolaryngology and Head and Neck Surgery, the Affiliated BenQ Hospital of Nanjing Medical University between June 2019 and December 2023 were reviewed, of whom 9 patients presented with metastatic squamous cell carcinoma in cervical lymph nodes of unknown primary or with no recurrence of primary lesion and all the 9 patients were males, aged from 48 to 79 years old, with≤level 2 of Eastern Cooperative Oncology Group-Performance Status (ECOG-PS). Radiographically common carotid artery (CCA) and/or internal carotid artery (ICA) were surrounded by≥270° with tumor. All the 9 patients received implantation of covered stent in carotid artery and radical resection of metastatic cervical lymph nodes. The success rate, complications, surgery-related complications, local recurrence rate, quality of life (QOL) and overall survival (OS) were analyzed. The QOL of patients was compared by paired rank sum test, and P<0.05 indicated statistically significant difference. The OS was analyzed by Kaplan-Meier. Results:The success rate of stent implantation was 100%, with no implantation-related complications. R0 resection was performed in 8 cases and R1 resection in 1 case. The QOL of patients after surgery was improved, and the improvements in "pain", "mood" and "anxiety" were statistically significant( Z values were -2.236, -2.460 and -2.200, respectively, and all P values were<0.05). Follow-up was 1-18 months, with a median of 7 months, and 1 case was lost to follow-up. Local recurrence occurred in 3 patients with an incidence of 37.5% (3/8). OS was 59.9% at 12 months after surgery. Conclusion:Implantation of covered stent in carotid artery combined with radical resection is an effective method for the treatment of cervical lymph node metastasis.

Objective To investigate the role and mechanism of silent information regulator 1(SIRT1)-NOD-like receptor protein 3(NLRP3)axis in the effect of remifentanil against ischemia-reperfusion injury(IRI)in rat livers.SD rats were randomly divided into sham operation group(sham group),IRI group,IRI+remifentanil pretreatment group(IRI+RPC group),IRI+SIRT1 inhibitor EX-527 group(IRI+EX-527 group)and IRI+RPC+EX-527 group,with 8 rats in each group.The levels of serum alanine aminotransferase(ALT),aspartate aminotransferase(AST),lactate dehydrogenase(LDH),interleukin(IL)-1β and IL-18 of rats in each group were detected.The liver tissue pathology was observed.The apoptosis rate of hepatocytes in rats was detected.The expressions of SIRT1,NLRP3,cleaved cysteinyl aspartate specific proteinase-1(Cleaved Caspase-1)and Gasdermin D(GSDMD)proteins in rat liver tissue were detected.Results Compared with the sham group,the liver tissue pathological score and hepatocyte apoptosis rate of rats in the IRI group were increased,the serum ALT,AST,LDH,IL-1β,and IL-18 levels were increased,the relative expression of SIRT1 protein in liver tissue was decreased,and the relative expression of NLRP3,Cleaved Caspase-1,and GSDMD proteins were increased(all P<0.05).Compared with the IRI group,the liver tissue pathological score and hepatocyte apoptosis rate of rats in the IRI+RPC group were decreased,the serum ALT,AST,LDH,IL-1β,and IL-18 levels were decreased,the relative expression of SIRT1 protein in liver tissue was increased,and the relative expression of NLRP3,Cleaved Caspase-1,and GSDMD proteins were decreased;the liver tissue pathological score and hepatocyte apoptosis rate of rats in the IRI+EX-527 group were increased,the ALT,AST,LDH,IL-1β,and IL-18 levels were increased,the relative expression of SIRT1 protein in liver tissue was decreased,and the relative expression of NLRP3,Cleaved Caspase-1,and GSDMD proteins were increased(all P<0.05).Compared with the IRI+RPC group,the liver tissue pathological score and hepatocyte apoptosis rate in the IRI+RPC+EX-527 group were increased,the levels of ALT,AST,LDH,IL-1β,and IL-18 were increased,the relative expression of SIRT1 protein in liver tissue was decreased,and the relative expression of NLRP3,Cleaved Caspase-1,and GSDMD proteins were increased(all P<0.05).Conclusions SIRT1 may participate in the regulation of remifentanil against rat liver IRI by inhibiting NLRP3 mediated cell pyroptosis.
