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.

Chemotherapy resistance in leukemia is an urgent clinical therapeutic challenge.Ferroptosis is a unique mode of cell death driven by iron-dependent phospholipid peroxidation.Leukemia is characterized by increased oxidative stress and iron overload,suggesting that leukemia cells might be susceptible to ferroptosis and indicating a possible therapeutic approach.Ferroptosis has been extensively studied in recent years and used in the treatment of various types of leukemia.Several studies have demonstrated an association between the regulatory pathways of ferroptosis and the mechanisms of leukemia drug resistance.The induction of ferroptosis through different pathways can effectively reduce the resistance of various types of leukemia cells to chemotherapeutic drugs,and thus improve their clinical efficacy.In this article,we review the regulatory mechanisms of ferroptosis and analyze the association between oxidative stress and iron metabolism pathways of ferroptosis and the mechanism of leukemia drug resistance.We also summarize the experimental studies and clinical applications of ferroptosis for the treatment of various types of drug-resistant leukemias,with the aim of providing new ideas and directions for the study of ferroptosis and a new strategy to reverse chemotherapy resistance in patients with leukemia in the future.

Objective To explore the effects of Tanganjianwan(TGJW)combined with abdominal massage(AM)on glucose and lipid metabolism and inflammatory factors in obesity and type 2 diabetes mellitus(OT2DM)patients with metformin treatment.Methods Patients with OT2DM diagnosed in Wuhan Hospital of Traditional Chinese Medicine from June 2021 to June 2023 were included as study subjects,and were divided into the AM group(metformin combined with AM)and the TGJW group(metformin combined with AM+TGJW)according to the random number table method.The treatment efficacy and safety were assessed by continuous intervention for 3 months.Obesity-related indices[waist-hip ratio(WHR)and body mass index(BMI)],glycemic and lipid metabolic indices[glycosylated hemoglobin(HbA1c),fasting blood glucose(FBG),postprandial 2-hour glucose(P2hG),total cholesterol(TC),triglycerides(TG),high-density lipoprotein cholesterol(HDL-C)and low-density lipoprotein cholesterol(LDL-C)],insulin sensitivity indexes[homeostasis model insulin resistance index(HOMA-IR)and homeostasis model pancreaticβ-cell function index(HOMA-β)],and inflammation indexes[interleukin-6(IL-6),tumor necrosis factor α(TNF-α),and C-reactive protein(CRP)]changes were compared before and after treatment between the TGJW group and the AM group.Results A total of 100 OT2DM patients were included in the study,with 50 cases each in the TGJW group and AM group.After the intervention,the treatment efficiency of the TGJW group was significantly higher than that of the AM group(P＜0.05),and no malignant adverse events occurred during treatment.Compared with the pre-treatment period,the levels of WHR,BMI,FBG,P2hG,HbA1c,TC,TG,LDL-C,HOMA-IR,IL-6,TNF-α,and CRP decreased in both groups(P＜0.05),while the levels of HDL-C and HOMA-β increased significantly(P＜0.05).After the intervention,the levels of WHR,BMI,FBG,P2hG,HbA1c,TC,TG,LDL-C,HOMA-IR,IL-6,TNF-α,and CRP in the TGJW group were lower than those in the AM group(P-＜0.05),while the levels of HDL-C and HOMA-β were higher than those in the AM group(P＜0.05).Conclusion Compared with AM treatment alone,TGJW combined with AM can improve glucose-lipid metabolism,insulin sensitivity and inflammation indexes in OT2DM patients,enhance the therapeutic effect of metformin treatment in OT2DM patients,and is safe,it has certain clinical promotion significance.

Objective:To evaluate the role of spinal Leucine-rich Repeat Kinase 2 (LRRK2) in neuropathic pain in rats.Methods:Fifty SPF healthy male Sprague-Dawley rats, aged 6-7 weeks, weighing 210-245 g, were divided into 5 groups ( n=10 each) using a random number table method: control group (C group), neuropathic pain group (NP group), low dose GNE-7915 group (low-dose GNE-7915 group), medium-dose GNE-7915 group (medium-dose GNE-7915 group), and high-dose GNE-7915 group (high-dose GNE-7915 group). Neuropathic pain was induced by the spared nerve injury in anesthetized rats. At 7 days after developing the model, LRRK2 inhibitor GNE-7915 12.5, 25.0 and 50.0 mg/kg were intraperitoneally injected in low-, medium- and high-dose GNE-7915 groups, respectively. The mechanical paw withdrawal threshold (MWT) and thermal paw withdrawal latency (TWL) were measured before developing the model, at 7 days after developing the model, and at 4 h after injecting the inhibitor. After measurement of the pain threshold, the rats were sacrificed and the spinal cord tissues were taken for determination of the positive expression of ionized calcium-binding adapter molecule 1(Iba-1) (by immunofluorescence staining), contents of interleukin-1β (IL-1β), monocyte chemotactic protein-1 (MCP-1) and IL-18 (by enzyme-linked immunosorbent assay), positive expression of phosphorylated LRRK2 (p-LRRK2) (by immunofluorescence staining), and expression of LRRK2, IL-1β, MCP-1 and IL-18 (by immunoblotting). The ratio of p-LRRK2/LRRK2 was calculated. Results:Compared with C group, the MWT was significantly decreased, the TWL was shortened, the proportion of Iba-1 and p-LRRK2 positive cells in spinal cord tissues, contents of IL-1β, MCP-1 and IL-18, and p-LRRK2/LRRK2 ratio were increased, and the expression of IL-1β, MCP-1 and IL-18 proteins was up-regulated in NP group ( P<0.05). Compared with NP group, the MWT was significantly increased, the TWL was prolonged, the proportion of Iba-1 and p-LRRK2 positive cells in spinal cord tissues, contents of IL-1β, MCP-1 and IL-18, and p-LRRK2/LRRK2 ratio were decreased, and the expression of IL-1β, MCP-1 and IL-18 proteins was down-regulated in low-, medium- and high-dose GNE-7915 groups ( P<0.05). Conclusions:LRRK2 in the spinal cord may be involved in the pathophysiological mechanism of neuropathic pain by activating microglia and inducing inflammatory responses in rats.

Background::The association and its population heterogeneities between low-density lipoprotein cholesterol (LDL-C) and all-cause and cardiovascular mortality remain unknown. We aimed to examine the dose-dependent associations of LDL-C levels with specific types of cardiovascular disease (CVD) mortality and heterogeneities in the associations among different population subgroups.Methods::A total of 2,968,462 participants aged 35-75 years from China Health Evaluation And risk Reduction through nationwide Teamwork (ChinaHEART) (2014-2019) were included. Cox proportional hazard models and Fine-Gray subdistribution hazard models were used to estimate associations between LDL-C categories (<70.0, 70.0-99.9, 100.0-129.9 [reference group], 130.0-159.9, 160.0-189.9, and ≥190.0 mg/dL) and all-cause and cause-specific mortality.Results::During a median follow-up of 3.7 years, 57,391 and 23,241 deaths from all-cause and overall CVD were documented. We observed J-shaped associations between LDL-C and death from all-cause, overall CVD, coronary heart disease (CHD), and ischemic stroke, and an L-shaped association between LDL-C and hemorrhagic stroke (HS) mortality ( P for non-linearity <0.001). Compared with the reference group (100.0-129.9 mg/dL), very low LDL-C levels (<70.0 mg/dL) were significantly associated with increased risk of overall CVD (hazard ratio [HR]: 1.10, 95% confidence interval [CI]: 1.06-1.14) and HS mortality (HR: 1.37, 95% CI: 1.29-1.45). Very high LDL-C levels (≥190.0 mg/dL) were associated with increased risk of overall CVD (HR: 1.51, 95% CI: 1.40-1.62) and CHD mortality (HR: 2.08, 95% CI: 1.92-2.24). The stronger associations of very low LDL-C with risk of CVD mortality were observed in individuals with older age, low or normal body mass index, low or moderate 10-year atherosclerotic CVD risk, and those without diagnosed CVD or taking statins. Stronger associations between very high LDL-C levels and all-cause and CVD mortality were observed in younger people. Conclusions::People with very low LDL-C had a higher risk of all-cause, CVD, and HS mortality; those with very high LDL-C had a higher risk of all-cause, CVD, and CHD mortality. On the basis of our findings, comprehensive health assessment is needed to evaluate cardiovascular risk and implement appropriate lipid-lowering therapy for people with very low LDL-C.

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.
