Objective:To explore the current situation of binary coping in patients with perimenopausal syndrome and analyze its influencing factors, in order to provide a basis for improving the level of binary coping.Methods:Using convenience sampling method, a total of 210 patients with perimenopausal syndrome and their spouses from the First Affiliated Hospital of Heilongjiang University of Traditional Chinese Medicine were cross-sectional surveyed by a general data questionnaire, the Binary Coping Scale, and the Modified Kupperman Score Scale. The influencing factors of binary coping level in patients with perimenopausal syndrome were explored by univariate analysis and variance decomposition model analysis.Results:A total of 200 valid questionnaires were retrieved.The patients aged (50.52 ± 2.89) years old. The binary coping score was (79.64 ± 22.74) points. The variance decomposition model analysis showed that marriage age, type of medical insurance, number of children, education level, family monthly income, spouse′s education level, presence of major comorbidities in spouse, modified Kupperman score, presence of generalized anxiety in spouse were the main influencing factors of binary coping in patients with perimenopausal syndrome (all P<0.05). Conclusions:The binary coping scores of patients with perimenopausal syndrome are lower than normal, and considering the influence and involvement of patients' spouses, nursing staff should pay special attention to patients who are married relatively early, have more children, have lower education levels, and have lower family monthly incomes. Additionally, attention should be given to spouses who experience widespread anxiety, have a lower level of education, and suffer from major chronic diseases. By developing and implementing comprehensive intervention measures aimed at improving the Kupperman score and the level of binary coping, both parties can be encouraged to support each other more effectively, thereby improving the marital relationships of patients during the perimenopausal period.

Traf2- and Nck-interacting kinase (TNIK) is closely related to the cancer occurrence, development, and prognosis. TNIK plays an important role in regulating Wnt/β-catenin pathway, thus becoming a potential target for cancer treatment. Various small-molecule TNIK inhibitors with diverse structures and potent in vitro activities have been developed to treat tumors. However, no TNIK inhibitor has entered clinical phase mainly due to poor selectivity, toxicity, and unsatisfied in vivo anti-tumor efficiency. This review summarizes the research progress of small molecule inhibitors targeting TNIK, with the aim of giving some guidance for future research and development of small-molecule inhibitors.

Acute lung injury (ALI), in which various factors inside and outside the lung lead to hypoxemic respiratory insufficiency and even the development of acute respiratory distress syndrome, has a high morbidity and mortality rate, and its pathogenesis is characterized by complex signaling pathways and limited therapeutic options. A large number of studies have reported that nuclear factor kappa B (NF-κB), phosphatidylinositol 3-kinase (PI3K)/Akt, mitogen-activated protein kinase (MAPK), AMP-activated protein kinase (AMPK), vascular endothelial growth factors (VEGF) and JAK/signal transducer and activator of transcription (STAT) signaling pathways are all related to the inflammatory response of ALI, and they are involved in regulating the inflammatory response process of ALI individually or cooperatively. Therefore, this article reviews the research progress on the pathogenesis-related signaling pathways and the drug interventions, aiming to provide a reference for early intervention in lung injury, optimizing the donor pool to increase the proportion of donation after cardiac death and providing quality donor protection conditions.

Objective:To investigate the effect and molecular mechanism of miR-15a-5p regulation Wnt signaling pathway in PQ-induced pulmonary fibrosis.Methods:The PQ-induced 16HBE cell model was constructed, high-throughput miRNA chip and RT-qPCR were used to screen for miR-15a-5p with significant differences. The experimental groups were as follows: NC group (normal control);no special treatment; PQ group: 50 μmol/L PQ treated cells for 72 h; miR-15a-5p group: 16HBE stable cell lines transfected with miR-15a-5p overexpressing lentivirus; miR-15a-5p+PQ group: Stable cell lines were treated with 50 μmol/L PQ for 72 h. The expression of Wnt pathway-related genes Wnt3α and β-catenin, fibroblast marker genes Collagen I, Vimentin and α SMA, epithelial marker genes Occludin and CK18 were detected by RT-qPCR and Western blot. The mice model of PQ-induced pulmonary fibrosis was constructed, and the protein expression and lung tissue injury were detected by Western blot, HE staining and immunohistochemistry. Data were expressed as mean ± standard deviation, and independent sample t-test was used to analyze the data between the two groups. Results:The expressions of Wnt3α, β-catenin, fibroblast marker genes Collagen I, Vimentin and α SMA significantly up-regulated in cell injury models ( P<0.05), the epithelial cell marker genes Occludin and CK18 significantly down-regulated ( P<0.05), overexpression of miR-15a-5p could inhibit the expression of Wnt3α and alleviated the EMT induced by PQ. In animal models, Wnt3α, β-catenin, fibroblast marker genes Collagen I, Vimentin and α SMA significantly increased ( P<0.01), the structure of lung tissue was disordered and fibrosis occurred, overexpression of miR-15a-5p inhibited the expression of Wnt3α protein ( P<0.05) and ameliorated lung tissue injury. Conclusions:miR-15a-5p ameliorates PQ-induced lung injury by modulating the Wnt3α/β-catenin signaling pathway, thereby inhibiting the development of pulmonary fibrosis.

Objective:To explore the protective mechanism of Xuebijing injection (referred to as Xuebijing) on sepsis-associated acute respiratory distress syndrome (ARDS).Methods:① Animal experiments: 100 mice were randomly(random number) divided into 4 groups, including sham operation (Sham) group, cecal ligation and puncture (CLP) group, CLP+low-dose Xuebijing (L-XBJ) group, and CLP+high-dose Xuebijing (H-XBJ) group. The survival rate, lung histological changes, lung wet/dry (W/D) ratio, cell count and protein concentration in bronchoalveolar lavage fluids (BALF), inflammatory factors levels in serum, oxidative stress indicators, cell apoptosis, and key proteins of HIF-1α/p38 MAPK/NF-κB signaling pathway were measured. ② Cell experiments: Mouse alveolar macrophages (MH-S) were cultured in vitro and divided into 6 groups, including control (Con) group, lipopolysaccharide (LPS) group, LPS+L-XBJ group, and LPS+H-XBJ group, LPS+H-XBJ+ dimethyloxallyl glycine (DMOG, HIF-1α activator) group, LPS+H-XBJ+ 2-methoxyestradiol (2ME2, HIF-1α inhibitor) group. The effects of Xuebijing on inflammatory factors, oxidative stress, and cell apoptosis and their relationship with HIF-1α/p38 MAPK/NF-κB signaling pathway were detected.Results:Xuebijing increased the survival rate of mice with sepsis-associated ARDS, relieved lung tissue damage [lung injury score: CLP group (8.778±0.588), CLP+L-XBJ group (5.833±0.310), and CLP+H-XBJ group (4.750±0.246)], alleviated lung W/D ratio, and decreased pneumonia cell infiltration and protein exudation (all P<0.05). Additionally, Xuebijing treatment also diminished the expression of inflammatory factors (TNF-α, IL-1β, and IL-6), intracellular reactive oxygen species (ROS) accumulation, malondialdehyde (MDA) formation, superoxide dismutase (SOD) depletion, and cell apoptosis in LPS-induced MH-S cells and CLP-induced sepsis-associated ARDS mice (all P<0.05). Furthermore, mechanistic investigation further clarified the effects of Xuebijing on inflammation, oxidative stress, and cell apoptosis through the HIF-1α/p38 MAPK/NF-κB signaling pathway. Conclusions:Xuebijing can exert anti-inflammatory, anti-oxidative, and anti-apoptotic effects by suppressing the HIF-1α/p38 MAPK/NF-κB signaling pathway, thereby conferring protection against sepsis-associated ARDS.

Objective In this study,we compared the masticatory efficiency,occlusal functional indexes,and satisfaction of lingual-ized occlusion(LO)vs.anatomic occlusion(AO)and discussed the difference between these occlusions.Methods Twenty edentulous patients were included in this clinical trial during 2021 April to December.They were divided into 2 groups according to their denture occlusion.Masticatory efficiency was tested by chewing the same amount of peanuts(by weight)and then the absorption of the solution was compared under a spectrophotometer after wearing dentures for 1 month.The TeeTester occlusion analysis system was used to test masticatory function,and satisfaction research was conducted for the edentulous patients at this time point as well.Finally,statistical analyses were conducted to compare the difference in masticatory efficiency between AO and LO by SPSS 20.0.Results The indexes of LO were worse than AO in masticatory efficiency,masticatory function and most of satisfaction research,while LO was better than AO in speech recovery.The difference was only statistically significant in COF-y of masticatory function(P＜0.05).Conclusion LO is similar with AO in terms of masticatory efficiency,satisfaction and denture stability;LO has good performance in denture's fit and use for patients.

Objective To investigate the results of ambulatory electrocardiographic(ECG)monitoring in a community-based homebound elderly population and to explore the applicability of wearable long-range ambulatory ECG monitor for them.Methods Elderly volunteers were recruited in Shuangbei Community,Shapingba District,Chongqing,from November 2021 to June 2023.A single-lead wearable ambulatory ECG recorder was applied to them to obtain ECG for 7 consecutive days.The adverse reactions,acceptability,monitoring duration,and arrhythmia detection rate during the wearing were described and recorded.Serious arrhythmic events included frequent atrial premature,atrial flutter,atrial fibrillation(AF),frequent ventricular premature,and RR intervals ≥5 s.Results There were 416 individuals enrolled,with a mean age of 71.2±6.6 years,and a male percentage of 36.1％(150 men).Finally,384(92.3％)participants completed the wearing of the ECG monitor for 7 d,with an average time of 159.2±29.4 h.There were 179 participants(48.5％)reporting no discomfort during wearing,and 175 ones(47.4％)feeling itchy at the wearing site.The monitoring results showed that the common arrhythmias were atrial premature contractions(97.1％),premature ventricular contractions(93.3％),atrial tachycardia(84.6％),bradycardia(46.6％),frequent atrial premature contractions(15.1％),ventricular tachycardia(13.2％),and long RR interval(11.8％).Among them,29.1％of the participants experienced serious arrhythmic events,and the detection rate of certain serious arrhythmic events was comparatively higher in the individuals≥70 years of age and those with history of previous cardiac disease.Conclusion The detection rate of common arrhythmias is quite high in the community-based homebound elderly population.A 7-day long-range ambulatory ECG monitoring may be appropriate.

Objective To analyze and construct systolic blood pressure(SBP)fluctuation trajectory in a community population with hypertension and to analyze the factors influencing different trajectories.Methods This is a community-based retrospective cohort study.A latent class trajectory model was used to identify and construct longitudinal trajectories of blood pressure change.Multinomial logistic regression analysis was performed to identify the associated factors of blood pressure trajectories by adjusting for different confounders.Potential confounding factors were identified using a directed acyclic graph based on a priori knowledge.Results A total of 793 patients with hypertension were enrolled in the analysis.They were divided into 3 groups by LCTM-fitted systolic blood pressure trajectories,namely stable low-level group(n=561,70.74％),declining group(n=170,21.44％)and rising group(n=62,7.82％).Significant differences were observed among the 3 trajectories groups in terms of age,frequency of exercise,ways of follow-up,salt intake,compliance behavior,and referral(P＜0.05).Compared to the stable low-level group and adjusting for corresponding confounding factors,the male patients and the patients with"outpatient follow-up"were more likely to be classified into"declining group",with OR and 95％CI of 1.436(1.016～2.030)and 1.702(1.202～2.410),respectively.The participants aged ≥ 65 years,who did not exercise or occasionally exercised,and had moderate and severe salt intake,were more likely to be classified into the"rising group"(OR=1.949,2.284,2.433,4.540,95％CI:1.145～3.317,1.305～3.998,1.272～4.654,1.291～15.963).Conclusion SBP trajectories in community-dwelling hypertensive population can be divided into stable low-level,declining and rising groups.Gender,age,salt intake,exercise frequency,and follow-up methods may be influencing factors for SBP blood pressure trajectory.

Methamphetamine abuse is a major public health problem in the world,and in recent years,methamphetamine is also the most abused synthetic drug in China.The neurotoxic or addiction mechanism of methamphetamine has not been fully clarified,and there is still a lack of specific withdrawal methods and drugs for methamphetamine abuse.Mitochondria are not on-ly the organelles to which methamphetamine directly produces toxic effects,but also participate in regulating the neurotoxic damage process of methamphetamine.Mitochondrial quality is the regulatory basis for maintaining mitochondrial homeostasis and is regulated by three main mechanisms,which are mitochon-drial biogenesis,mitochondrial dynamic,and mitophagy.This review summarizes the research progress of mitochondrial quality control in methamphetamine-induced neurotoxicity,which may provide theoretical support for further research on the mechanism of methamphetamine neurotoxicity and development the mito-chondria-targeting drugs.

Objective:To explore the mediating effect of carotid atherosclerosis on serum triglyceride-glucose (TyG) index and silent lacunar infarction (SLI) in non-diabetic population.Methods:A total of 2 482 patients were selected from the Health Examination Center of Hebei General Hospital from January 2019 to December 2021. The basic demographic information, biochemical parameters, calculated TyG index and carotid plaque score were collected. SLI was diagnosed according to the criteria formulated by Chinese Society of Neurology. Participants were divided into SLI group and non-SLI group according to whether there was SLI in brain magnetic resonance imaging, and the non-SLI group was normal without lacunar infarction. Spearman correlation analysis was used to explore the correlation between TyG index and carotid plaque score. Binary Logistic regression analysis was used to analyze the effects of TyG index and carotid plaque score on SLI. Bootstrap was used to explore whether carotid plaque score mediated the association between TyG index and SLI.Results:There were 471 patients (18.98%) who had SLI, and 2 011 patients (81.02%) did not. Carotid plaque score [2(0, 5) vs 1(0, 3)] and TyG index [7.17(6.81, 7.64) vs 7.12(6.77, 7.54)] were increased in the SLI group compared with the non-SLI group ( Z=-4.213, Z=-2.636, P<0.05). Spearman correlation analysis showed that carotid plaque score was positively correlated with TyG index ( r=0.083, P<0.001). Multivariate Logistic regression analysis indicated that carotid plaque score ( OR=1.047, 95% CI 1.002-1.094) and TyG index ( OR=1.329, 95% CI 1.106-1.598) were independent risk factors for SLI ( P<0.05). Mediated effect analysis showed that TyG index had a direct effect on the incidence of SLI (β=0.265, 95% CI 0.102-0.428). Carotid plaque score partially mediated the effect of TyG index on the incidence of SLI (β=0.024, 95% CI 0.009-0.043), and the mediating effect accounted for 8.30% of the total effects. Conclusion:In non-diabetic population, TyG index and carotid plaque score are predictors of SLI, and the carotid plaque score is a partial mediator in the effect of TyG index on the incidence of SLI.
