It is very limited that the benefit of perioperative chemotherapy in early non-small cell lung cancer (NSCLC), and the 5-year survival rate is only 5% higher than surgery. Antibodies that block programmed cell death protein 1/programmed death-ligand 1 significantly improve the survival of advanced NSCLC. The value of immunotherapy in early NSCLC is also being explored. This paper firstly summarized and analyzed the progress of immunotherapy in the perioperative period of NSCLC. Secondly, the safety and feasibility of surgical resection after neoadjuvant immunotherapy were discussed. Finally, the clinical value of different therapeutic efficacy prediction indicators was summarized, in order to clarify the current status of immunotherapy in the perioperative period, so as to improve the clinical benefits of early NSCLC patients.

Objective: To explore the relationship between social jetlag and depressive symptoms in junior high school students, as well as the potential gender differences, so as to provide a reference for developing effective interventions for depressive symptoms and promoting adolescents mental health. Methods: In October 2024, a total of 3 516 students from grades 7 to 9 were recruited from 4 junior high schools in Chongqing Municipality using a combination of cluster sampling and convenience sampling. A questionnaire survey was conducted using the Center for Epidemiologic Studies Depression Scale (CES-D) and the Munich Chronotype Questionnaire (MCTQ). Statistical analyses included the χ 2 test, binary Logistic regression analysis, and stratified Logistic regression analysis. Results: The detection rate of depressive symptoms among the junior high school students was 34.3%. The number of students with social jetlag >2 h was 714 (20.3%), >1-2 h was 1 455(41.4%), and ≤1 h was 1 347(38.3%). Results from the binary Logistic regression analysis showed that compared to the group with social jetlag ≤1 h, the risk of depressive symptoms in the group with social jetlag >2 h was higher ( OR=1.59, 95%CI=1.28-1.98, P <0.01). Gender stratified analysis revealed that among females, the risk of depressive symptoms was higher in the groups with social jetlag of >1-2 h and >2 h compared to the ≤1 h group ( OR = 1.34 and 2.05, 95% CI =1.03-1.75 and 1.48-2.83, both P <0.05). However, among males, the associations were not statistically significant ( OR =1.11 and 1.29, 95% CI =0.86-1.43 and 0.95-1.77, both P >0.05). Conclusions Social jetlag is positively associated with depressive symptoms in junior high school students, demonstrating a threshold effect and gender differences. The findings suggest that reducing social jetlag may decrease the risk of depressive symptoms in adolescents, and targeted intervention measures should be developed considering different gender characteristics.

As a common pathological state in clinical practice， Chong Mai Wei Bing （冲脉为病） is typically manifested as rebellious qi and a sense of urgency. It often involves various diseases caused by the disorder of qi circulation. From the perspectives of theoretical foundation， pathological characteristics， and clinical differentiation and treatment， this paper elaborates on the characteristics of Chong Mai （冲脉） as the cause of disease， including three main manifestations： upward qi surge， upward yin fire， and upward water-qi. Among these， the upward qi surge is further categorized into four aspects： Chong Qi （冲气） counterflow， counterflow of stomach qi， counterflow of kidney qi， and counterflow of liver qi. Three major treatment methods are proposed： pacifying the Chong Mai and reversing the counterflow， consolidating Chong Mai to subdue fire， and warming Chong Mai to resolve qi and promote water flow. This paper summarizes its practical application in clinical diagnosis and treatment， aiming to deepen the understanding of the functional and pathological mechanisms of Chong Mai， and to provide insights and methods for the traditional Chinese medicine diagnosis and treatment of various diseases.

In recent years, with the continuous development and increasing maturity of interventional techniques, interventional treatment for congenital heart disease (CHD) has been progressively disseminated to county- and city-level hospitals in China. Concurrently, the standardized management of adult CHD (particularly patent foramen ovale) and the lifelong management of complex CHD are gaining increasing clinical attention, while the emergence of new techniques and products continuously advances the discipline. This article aims to review the new progress made in the field of interventional treatment for congenital heart disease in China during 2024. It specifically reviews and analyzes the following key aspects: (1) annual statistics on interventional closure procedures for CHD; (2) recent insights into patent foramen ovale closure; (3) advances in transcatheter pulmonary valve replacement; (4) interventional treatment and lifelong management strategies for complex CHD; (5) new interventional techniques for acquired heart disease; and (6) the application of artificial intelligence in CHD management. Through the synthesis and discussion of these topics, this article seeks to provide a detailed analysis of the current landscape of interventional treatment for CHD in China and project its future development trends.

Objective: To explore the independent effects and gender differences of different types of adverse childhood experiences (ACEs) on the co-occurrence of non-suicidal self-injury (NSSI) and suicide attempts (SA), so as to provide a reference for the precise prevention and control of self-harm in junior high school students. Methods: From May to June 2023, a total of 7 360 junior high school students were selected from 12 schools in three districts/counties of Chongqing using a combination of stratified cluster sampling and convenience sampling methods. Information on NSSI, SA, ACEs, and depressive symptom, as well as other related data were collected through the Adolescent Non-suicidal Self-injury Assessment Questionnaire (ANSAQ), suicide related section of the Chinese Adolescent Health related Behavior Questionnaire (Junior High School Version), Childhood Trauma Questionnaire-Short Form ( CTQ- SF), and Center for Epidemiologic Studies-Depression Scale (CES-D). Statistical analyses of the data were performed using the Chi-square test and multiple Logistic regression. Results: The detection rates of NSSI, SA, NSSI+SA and ACEs in junior high school students were 19.2%, 4.6%, 3.5% and 57.9% respectively. After controlling for factors such as gender, grade, family type, self rated family economic status, self rated academic performance, self rated academic pressure, number of close friends, and depressive symptom scores, results from the multiple Logistic regression analysis showed that junior high school students with physical abuse ( OR = 1.98, 95% CI =1.23-3.18), emotional abuse ( OR =2.83, 95% CI =1.92-4.19), sexual abuse ( OR = 1.70, 95% CI =1.07- 2.69 ), physical neglect ( OR =1.67, 95% CI =1.20-2.33) and witnessing domestic violence ( OR =2.10, 95% CI =1.41-2.87) in childhood had higher risks for the occurrence of NSSI+SA (all P <0.05). After stratification by gender, boys with sexual abuse in childhood had a high risk for the occurrence of NSSI+SA ( OR =2.17, 95% CI =1.06-4.43), whereas girls with emotional abuse ( OR =3.69, 95% CI =2.29-5.94), physical neglect ( OR =1.62, 95% CI =1.07-2.45) and witnessing domestic violence ( OR =2.17, 95% CI =1.41-3.34) in childhood had hgih risks for the occurrence of NSSI+SA (all P <0.05). Conclusions Different types of ACEs have different effects on the co-occurrence of self-harm in junior high school students and there are gender differences. When family interventions are conducted for the combined model, emphasis should be placed on aspects of emotional abuse and domestic violence while optimizing the interventions based on gender differences.

Objective: To explore the mediating role of balanced time perspective in the relationship between social jetlag and depressive symptom among junior high school students, so as to privide a basis for improving their mental health. Methods: In October 2024, a method of combining convenient sampling with cluster sampling was used to select 3 438 junior high school students from two districts(Yubei District and Kaizhou District) in Chongqing. The Center for Epidemiological Studies Depression Scale (CES-D), Munich Chronotype Questionnaire (MCTQ), and Balanced Time Perspective Inventory (BTPI) were administered for the survey. Statistical analyses included t-test, ANOVA, and Spearman correlation analysis, and conduct a mediation effect analysis using the Process program. Results: The mean score of depressive symptom among junior high school students was 15.00(9.00, 23.00 ), social jetlag was 1.18(0.72, 1.83) hours, and balanced time perspective score was -0.18(-2.82, 2.93). Social jetlag among junior high school students was positively correlated with depressive symptom score ( r =0.17), while balanced time perspective was negatively correlated with social jetlag ( r =-0.15) and depressive symptom score ( r =-0.68) (all P <0.01). Mediation analysis showed that balanced time perspective partially mediated the relationship between social jetlag and depressive symptom ( β=0.68, P <0.01) among junior high school students, accounting for 53.97% of the total effect. Conclusions Social jetlag of junior high school students influences depressive symptoms by affecting balanced time perspective. Efforts should be made to improve adolescents balanced time perspective for reducing the impact of social jetlag on depressive symptom.

Objective: To explore the potential subgroups of emotion regulation strategies among junior high school students and their moderating role in the relationship between parental psychological control and depressive symptom, so as to provide basis for improving mental health among junior high school students. Methods: In October 2024, a cluster sampling method was used to select 3 389 junior high school students from 4 secondary schools across 2 districts in Chongqing. Surveys were conducted by using Center for Epidemiological Survey-Depression Scale (CES-D), Chinese Parental Psychological Control Scale (CPPCS), and Emotion Regulation Questionnaire (ERQ). Latent profile analysis was applied to identify subgroups based on emotion regulation strategies, and multiple linear regression model was used to test the moderating effect of emotion regulation strategies on the association between parental psychological control and depressive symptom among junior high school students. Results: According to the two dimensions of emotion regulation strategies-cognitive reappraisal and expressive suppression, three distinct subgroups were identified:the moderate cognitive reappraisal-moderate expressive suppression subgroup (moderate-moderate subgroup, 64.2%), the low cognitive reappraisal-moderate expressive suppression subgroup (low-moderate subgroup, 9.6%), and the high cognitive reappraisal low expressive suppression subgroup (high-low subgroup, 26.1%). Hierarchical regression results indicated that both parental psychological control ( β =0.70) and deficits in cognitive reappraisal (low moderate subgroup, β =5.38) were associated with an increased risk of depressive symptoms, whereas the high-low subgroup appeared to mitigate depressive symptom ( β =-3.47) (all P < 0.01). Compared to the moderate-moderate subgroup, the low-moderate subgroup showed a statistically significant positive moderating effect on the relationship between parental psychological control and depressive symptom ( β =0.14, P <0.05), while the negative moderating effect of the high-low subgroup was not statistically significant ( β =-0.07, P >0.05). Conclusions The negative impact of parental psychological control on depressive symptom in junior high school students varies depending on the use of different emotion regulation strategies. For a majority of students, enhancing cognitive reappraisal training may help alleviate the adverse effects of parental psychological control and promote better mental health.

This review article summarizes the current modification methods employed to enhance the osseointegration properties of polyetheretherketone (PEEK), a novel biomaterial. Our analysis highlights that strategies such as surface treatment, surface modification, and the incorporation of bioactive composites can markedly improve the bioactivity of PEEK surfaces, thus facilitating their effective integration with bone tissue. However, to ensure widespread application of PEEK in the medical field, particularly in oral implantology, additional experiments and long-term clinical evaluations are required. Looking ahead, future research should concentrate on developing innovative modification techniques and assessment methodologies to further optimize the performance of PEEK implant materials. The ultimate goal is to provide the clinical setting with even more reliable solutions.

Objective:To explore the genetic etiology of a child with Spastic paraplegia and psychomotor retardation with or without seizures (SPPRS).Methods:A child who was admitted to the Children′s Hospital Affiliated to Nanjing Medical University in April 2022 for motor developmental delay, intellectual disability, and hypertonia was selected as the study subject. Relevant clinical data were retrospectively analyzed. Whole exome sequencing (WES) was carried out for the child and his parents. Candidate variants were searched in the Single Nucleotide Polymorphism Database (dbSNP) and Online Mendelian Inheritance in Man (OMIM) database. Pathogenicity of the variants was assessed based on guidelines from the American College of Medical Genetics and Genomics (ACMG). Using key words such as " HACE1 gene" " Spastic paraplegia and psychomotor retardation with or without seizures" and " SPPRS", previous reports on SPPRS patients due to HACE1 gene variants were retrieved from the CNKI, Wanfang Data Knowledge Service Platform, CQVIP, and PubMed databases, with the time set from January 1, 2000 to April 7, 2024. A mutation map for the HACE1 protein in the patients was created. This study was approved by the Ethics Committee of the Children′s Hospital Affiliated to Nanjing Medical University (Ethics No. 202404008-1). Results:The clinical manifestations of the child had included motor developmental delay, intellectual disability and hypertonia. Magnetic resonance imaging revealed hypoplasia of posterior corpus callosum and splenium, with slight enlargement of lateral ventricles. WES revealed that the child has harbored compound heterozygous variants of the HACE1 gene, namely c. 535(exon7)_c.538(exon7)delACAG (p.T179fs*5) and c. 1678+ 2(IVS15)T>C, which were respectively inherited from his parents. Based on the guidelines from the ACMG, the variants were respectively rated as likely pathogenic (PVS1 + PM2_Supporting) and pathogenic (PVS1 + PM2_Supporting + PM3). Literature search has identified 8 papers, which reported 23 SPPRS cases due to HACE1 gene variants. All patients exhibited psychomotor developmental delay, among whom 18 HACE1 gene variants were identified. Conclusion:The c. 535(exon7)_c.538(exon7)delACAG (p.T179fs*5) and c. 1678+ 2(IVS15)T>C compound heterozygous variants of the HACE1 gene probably underlay the pathogenesis of SPPRS in this child. Above discovery has enriched the mutational and phenotypic spectrum of the HACE1 gene and provided a reference for clinical diagnosis and genetic counseling.

Objective:To explore the clinical phenotype and variants of KIF4A gene associated with X-linked intellectual disability type 100 (XLID100) in a child by whole-exome sequencing (WES). Methods:A child presented at the Children′s Hospital Affiliated to Nanjing Medical University in September 2023 was selected as the study subject. Clinical data of the child was retrospectively analyzed. Peripheral blood samples were collected from the child and his family members for WES analysis. Candidate variant was verified by Sanger sequencing. Pathogenicity of the candidate variant was rated based on the guidelines from the American College of Medical Genetics and Genomics (ACMG). The variant was also searched in dbSNP, OMIM, HGMD, ClinVar and gnomAD databases. Amino acid sequences of the KIF4A protein across various species were retrieved from the Ensembl Genome Browser Database and analyzed using Clustal Omega software. Relevant literature on KIF4A gene mutations associated with XLID100 was reviewed. This study has been approved by the Medical Ethics Committee of the Hospital (Ethics No. 202402022-1). Results:The child, a 3-year-6-month-old male, had manifested intellectual impairment, language delay, autism, and choroid cyst revealed by cranial magnetic resonance imaging. No facial dysmorphism, tooth anomaly, gross motor development delay or regression, and history of seizure and febrile convulsion was noted. WES revealed that he has harbored a c. 3385delinsTATC (p.Thr1129delinsTyrPro) variant of the KIF4A gene. Sanger sequencing confirmed that his mother and sister have harbored the same variant, whilst his father was of the wild type. Both of his parents had a normal phenotype. The variant was classified as of uncertain significance based on the guidelines from the ACMG. It was not recorded by the dbSNP, OMIM, HGMD, ClinVar and the gnomAD database. Conservative analysis suggested that the variant site, which normally encodes a cysteine, is highly conserved among various species. A review of the literature had retrieved 6 relevant articles documenting a total of 27 cases of KIF4A gene mutations, with only one case from China. Conclusion:The c. 3385delinsTATC (p.Thr1129delinsTyrPro) variant of the KIF4A gene probably underlay the XLID100 in this child. Above finding has provided a reference for the clinical diagnosis and genetic counseling and enriched the mutation spectrum of the KIF4A gene.
