Objective To explore the causal relationship between family resilience and mental health in military personnel population.Methods A total of 204 military personnel were recruited from an army unit stationed in Western China with cluster convenience sampling.Family Resilience Scale(FRS)and Symptom Checklist 90(SCL-90)were used to survey them twice,in an interval of 4 months.Amos 26.0 was applied to construct a cross-lag model and analyze the data.Results After controlling mental symptoms from the first survey,family resilience in the first measure significantly predicted mental symptoms in the second measure(β=-0.14,P＜0.05).After controlling for family resilience from the first survey,mental symptoms in the first measure significantly predicted family resilience in the second measure(β=-0.13,P＜0.05).Conclusion The relationship between family resilience and mental health is mutually causal in military personnel,and one predicts the other one.Our findings highlight the key dimensions of the relationship between the two.

BACKGROUND:Confirming the reliability and validity of the My jump 2 application for measuring lower limb vertical stiffness may offer the possibility of it as an alternative to the Kistler three-dimensional force platform for measuring lower limb stiffness. OBJECTIVE:To verify the reliability and validity of the My Jump 2 application in measuring lower limb vertical stiffness of college students. METHODS:The drop jump data of the participants were collected through the Kistler three-dimensional force platform and the My Jump 2 application,and the vertical stiffness of the participants'lower limb vertical stiffness was calculated.The intraclass correlation coefficient was used to analyze the data measured by the My Jump 2 application and the Kistler three-dimensional force platform,attempting to verify the reliability of the My Jump 2 application.The bias and average between the two devices were drawn into a Bland-Altman diagram to verify the consistency between the two test methods.Finally,the test-retest reliability of the My Jump 2 applications at 30 cm and 40 cm was analyzed using the Cronbach's alpha(α)and coefficient of variation.Pearson product-moment correlation was used to analyze the correlation of My Jump 2 applications. RESULTS AND CONCLUSION:My Jump 2 application has high reliability and validity when measuring the vertical stiffness of the lower limb.At the same time,due to its advantages of low cost,convenient portability and field testing for large samples,it can be used as an alternative to the Kistler three-dimensional force platform to test the vertical stiffness of the lower limb in college students and similar populations.

Objective To screen out the biomarkers linked to prognosis of breast invasive carcinoma based on the analysis of transcriptome data by random forest(RF),extreme gradient boosting(XGBoost),light gradient boosting machine(LightGBM),and categorical boosting(CatBoost).Methods We obtained the ex-pression data of breast invasive carcinoma from The Cancer Genome Atlas and employed DESeq2,t-test,and Cox univariate analysis to identify the differentially expressed protein-coding genes associated with survival prog-nosis in human breast invasive carcinoma samples.Furthermore,RF,XGBoost,LightGBM,and CatBoost mod-els were established to mine the protein-coding gene markers related to the prognosis of breast invasive cancer and the model performance was compared.The expression data of breast cancer from the Gene Expression Omnibus was used for validation.Results A total of 151 differentially expressed protein-coding genes related to survival prog-nosis were screened out.The machine learning model established with C3orf80,UGP2,and SPC25 demonstrated the best performance.Conclusions Three protein-coding genes(UGP2,C3orf80,and SPC25)were screened out to identify breast invasive carcinoma.This study provides a new direction for the treatment and diagnosis of breast invasive carcinoma.

Temporomandibular joint (TMJ) diseases are common clinical conditions. The number of patients with TMJ diseases is large, and the etiology, epidemiology, disease spectrum, and treatment of the disease remain controversial and unknown. To understand and master the current situation of the occurrence, development and prevention of TMJ diseases, as well as to identify the patterns in etiology, incidence, drug sensitivity, and prognosis is crucial for alleviating patients′suffering.This will facilitate in-depth medical research, effective disease prevention measures, and the formulation of corresponding health policies. Cohort construction and research has an irreplaceable role in precise disease prevention and significant improvement in diagnosis and treatment levels. Large-scale cohort studies are needed to explore the relationship between potential risk factors and outcomes of TMJ diseases, and to observe disease prognoses through long-term follw-ups. The consensus aims to establish a standard conceptual frame work for a cohort study on patients with TMJ disease while providing ideas for cohort data standards to this condition. TMJ disease cohort data consists of both common data standards applicable to all specific disease cohorts as well as disease-specific data standards. Common data were available for each specific disease cohort. By integrating different cohort research resources, standard problems or study variables can be unified. Long-term follow-up can be performed using consistent definitions and criteria across different projects for better core data collection. It is hoped that this consensus will be facilitate the development cohort studies of TMJ diseases.

OBJECTIVE: To explore the clinical application value of mineralized collagen (MC) bone scaffolds in repairing various types of skull defects, and to assess the suitability and repair effectiveness of porous MC (pMC) scaffolds, compact MC (cMC) scaffolds, and biphasic MC composite (bMC) scaffolds. METHODS: A retrospective analysis was conducted on the clinical data of 105 patients who underwent skull defect repair with pMC, cMC, or bMC between October 2014 and April 2022. The cohort included 63 males and 42 females, ranging in age from 3 months to 55 years, with a median age of 22.7 years. Causes of defects included craniectomy after traumatic surgery in 37 cases, craniotomy in 58 cases, tumor recurrence or intracranial hemorrhage surgery in 10 cases. Appropriate MC scaffolds were selected based on the patient's skull defect size and age: 58 patients with defects <3 cm² underwent skull repair with pMC (pMC group), 45 patients with defects ≥3 cm² and aged ≥5 years underwent skull repair with cMC (cMC group), and 2 patients with defects ≥3 cm² and aged <5 years underwent skull repair with bMC (bMC group). Postoperative clinical follow-up and imaging examinations were conducted to evaluate bone regeneration, the biocompatibility of the repair materials, and the occurrence of complications. RESULTS: All 105 patients were followed up 3-24 months, with an average of 13 months. No material-related complication occurred in any patient, including skin and subcutaneous tissue infection, excessive ossification, and rejection. CT scans at 6 months postoperatively showed bone growth in all patients, and CT scans at 12 months postoperatively showed complete or near-complete resolution of bone defects in all patients, with 58 cases repaired in the pMC group. The CT values of the defect site and the contralateral normal skull bone in the pMC group at 12 months postoperatively were (1 123.74±93.64) HU and (1 128.14±92.57) HU, respectively, with no significant difference ( t=0.261, P=0.795). CONCLUSION MC exhibits good biocompatibility and osteogenic induction ability in skull defect repair. pMC is suitable for repairing small defects, cMC is suitable for repairing large defects, and bMC is suitable for repairing pediatric skull defects.

Zhishi Xiebai Guizhitang is a classical prescription for the treatment of chest impediment with the method of warming Yang. It is included in the Catalogue of Ancient Classical Prescriptions issued by the National Administration of Traditional Chinese Medicine （First Batch）， with the effect of activating Yang， dissipating mass， moving Qi and resolving phlegm. Its main symptoms include chest fullness and pain， or even chest pain radiating to the back， wheezing， coughing， shortness of breath， and Qi reversal from the hypochondrium. In modern traditional Chinese medicine， Zhishi Xiebai Guizhitang is clinically used in the treatment of cardiovascular system， digestive system， respiratory system and other diseases， among which coronary heart disease， unstable angina pectoris， myocardial infarction， sinus bradycardia and other cardiovascular diseases have particularly significant effects. This paper reviewed the pharmacological studies of Zhishi Xiebai Guizhitang in the past 10 years. The results showed that each single medicine and the whole prescription alleviated the above cardiovascular diseases to a certain extent， with the pharmacological effects of improving intravascular environment， myocardial ischemia， myocardial ischemia-reperfusion injury， and myocardial hypoxia， anti-inflammation， plaque stabilisation， etc.， and the pharmacological mechanism involved the regulation of relevant active substances in vivo as well as related signaling pathways and ion channels， mainly including thromboxane B₂ （TXB₂）， prostacyclin I₂（PGI₂） and phosphatidylinositol 3-kinases/protein kinase B/endothelial nitric oxide synthase （PI3K/Akt/eNOS） signaling pathways， and ATP-sensitive potassium channels. In addition， the relationship between the pharmacological effects of some single medicines and transient receptor potential ankyrin 1 （TRPA1） has been reported that TRPA1 is a key to understanding the mechanism of Zhishi Xiebai Guizhitang in treating cardiovascular diseases， which is worth of further study.
