OBJECTIVE: This study aimed to evaluate the association between susceptibility genes and non-alcoholic fatty liver disease (NAFLD) in children with obesity. METHODS: We conducted a two-step case-control study. Ninety-three participants were subjected to whole-exome sequencing (exploratory set). Differential genes identified in the small sample were validated in 1,022 participants using multiplex polymerase chain reaction and high-throughput sequencing (validation set). RESULTS: In the exploratory set, 14 genes from the NAFLD-associated pathways were identified. In the validation set, after adjusting for sex, age, and body mass index, ECI2 rs2326408 (dominant model: OR = 1.33, 95% CI: 1.02-1.72; additive model: OR = 1.22, 95% CI: 1.01-1.47), C6orf201 rs659305 (dominant model: OR = 1.30, 95% CI: 1.01-1.69; additive model: OR = 1.21, 95% CI: 1.00-1.45), CALML5 rs10904516 (pre-ad dominant model: OR = 1.36, 95% CI: 1.01-1.83; adjusted dominant model: OR = 1.40, 95% CI: 1.03-1.91; and pre-ad additive model: OR = 1.26, 95% CI: 1.04-1.66) polymorphisms were significantly associated with NAFLD in children with obesity ( P < 0.05). Interaction analysis revealed that the gene-gene interaction model of CALML5 rs10904516, COX11 rs17209882, and SCD5 rs3733228 was optional ( P < 0.05), demonstrating a negative interaction between the three genes. CONCLUSION In the Chinese population, the CALML5 rs10904516, C6orf201 rs659305, and ECI2 rs2326408 variants could be genetic markers for NAFLD susceptibility.

Objective:To identify proteins associated with the risk of gastric cancer (GC) and build a protein risk score for risk prediction of GC based on proteomic analysis.Methods:Gastric mucosal proteomics data were used to construct Dataset One, comprising 94 GC cases and 230 individuals with different stages of gastric mucosal lesions. The GC cases were recruited from the National Upper Gastrointestinal Cancer Early Detection (UGCED) Program in Linqu, Shandong Province, as well as clinical patients from the Fifth Medical Center, General Hospital of PLA, and Peking University Cancer Hospital. Non-cancer individuals were enrolled from the National UGCED Program in Linqu and community screening programs at the Dongfang Hospital. All participants were pathologically confirmed. Multivariate logistic regression analysis was employed to identify gastric mucosal proteins significantly associated with GC risk. Subsequently, plasma proteomics data from the UK Biobank Pharma Proteomics Project (UKB-PPP) were used to construct Dataset Two, including 40 baseline GC cases and 47 933 non-cancer individuals, and Dataset Three, comprising 138 incident GC cases and 47 933 non-cancer individuals during a prospective follow-up period. In Dataset Two, multivariate logistic regression analysis was conducted to assess associations between plasma protein levels and baseline GC risk. In Dataset Three, multivariate Cox regression analysis was used to examine associations with the risk of incident GC. A poly-protein risk score (PRS) was developed using a weighted summation method based on protein effect sizes from Dataset Two. Its associations with GC risk and the progression of gastric mucosal lesions were evaluated using linear regression trend tests.Results:A total of 324, 47 973 and 48 071 participants were included in Datasets One, Two, and Three, respectively. Across the three datasets, the proportions of males and individuals aged>60 years were higher in the GC group than in the non-GC group (all P values<0.05). The follow-up period in Dataset Three had a M ( P 25, P 75) of 14.47 (13.7, 15.2) years, with a median of 7.4 (4.6, 11.3) years for those who progressed to GC. Based on Dataset One, 2 524 tissue-differential proteins associated with GC risk were identified through multivariate logistic regression analysis adjusted for age and sex. Among these, seven proteins were consistently associated with GC risk across tissue and plasma levels in Datasets Two and Three, with consistent directions of association. Five proteins (MRC1, APOL1, BST2, PON2, and GGH) were positively associated with GC risk, while two (GSN and CLEC3B) were negatively associated. Analysis of the PRS based on these seven proteins showed that for each standard deviation increase in the tissue-derived PRS, the risk of GC increased by 6.26 times (95% CI: 4.02-9.75). In Dataset Two, each standard deviation increase in the plasma-derived PRS was associated with a 2.13-fold increase in GC risk (95% CI: 1.68-2.69). In the prospective cohort of Dataset Three, individuals in the high PRS group had a 2.27-fold higher risk of GC compared to the low PRS group (95% CI: 1.50-3.45). Moreover, each standard deviation increase in the plasma PRS was associated with a 57% higher risk of GC ( HR=1.57, 95% CI: 1.34-1.84). Additionally, the tissue-derived PRS showed an increasing trend with the progression of gastric mucosal lesions. Conclusion:The tissue and plasma proteomics identified seven individual proteins that may indicate the risk of developing gastric cancer, showing the potential as biomarkers for aiding in the screening of gastric cancer.

Objective To screen specific antibodies to Helicobacter pylori(H.pylori)in serum,and establish antibody panels and discrimination models for different infection status,which are non-invasive and suitable for gastric cancer screening in Chinese population.Methods A total of 300 subjects with different H.pylori statuses were enrolled depending on an endoscopy screening cohort in a high-risk area of gastric cancer,including current,past,and negative infections.The recomLine Helicobacter IgG 2.0 immunoblotting assay was used to analyze and screen 10 H.pylori specific antibodies in serum samples.Results A total of nine antibody reactivity against CagA,VacA,GroEL,FliD,HpaA,gGT,HtrA,NapA,and CtkA showed significant differences among different H.pylori infection status groups(all P＜0.05).A panel comprising the nine antibodies distinguished exposure subjects to H.pylori(current and past infections)from negatives,with an area under the curve(AUC)of 0.935(95%CI:0.907-0.963).The combination of four antibodies(CagA,GroEL,FliD,and gGT)may help to discriminate current and past infection subjects,with an AUC of 0.927(95%CI:0.891-0.964).Conclusion The antibody panels and discriminant models for H.pylori infection status established in the present study may provide a potential and non-invasive screening method for the development of precise gastric cancer prevention strategies.

Objective:To observe the improving effect of acupuncture and Tuina(Chinese therapeutic massage)combined with Ba Duan Jin(Eight-brocade Exercise)on motor function in patients with Parkinson disease(PD)in the early and middle stages.Methods:Seventy patients with early-or middle-stage PD were randomly divided into a control group and an observation group,with 35 patients in each group.The control group was given conventional treatment such as oral levodopa hydrochloride tablets;the observation group was treated with acupuncture,Tuina,and Ba Duan Jin in addition to the control group's treatment.Acupuncture and Tuina were administered twice a week,and Ba Duan Jin was performed five times a week.Each course of treatment lasted 4 weeks,and a total of 3 courses were completed.The changes in the unified Parkinson disease rating scale Ⅲ(UPDRS Ⅲ)score,Berg balance scale(BBS)score,15-meter walking speed,and 6-minute walk distance were compared between the two groups.Results:The total effective rate in the observation group was 93.6%,which was significantly higher than 45.7%in the control group(P<0.01).After 4,8,and 12 weeks of treatment,the UPDRS Ⅲ score in the observation group was significantly lower than the previous score(P<0.05);the BBS score was significantly higher than the previous score(P<0.05),and the 6-minute walk distance also significantly increased compared to the previous result(P<0.05).After 8 and 12 weeks of treatment,the 15-meter walking speed in the observation group was significantly higher than that before treatment and the previous measurement(P<0.05).In comparison with the control group,the observation group showed significantly lower UPDRS Ⅲ scores after 8 and 12 weeks of treatment(P<0.05).Additionally,after 4,8,and 12 weeks of treatment,the observation group had significantly higher BBS scores,15-meter walking speed,and the 6-minute walk distance than the control group(P<0.05).There were no significant differences in the above indicators before and after treatment in the control group(P>0.05).Conclusion:The addition of acupuncture,Tuina,and Ba Duan Jin to Western medication treatment can effectively improve motor function,balance ability,and walking ability in patients with early-or middle-stage PD.

With the rapid development of competitive sports, the incidence of anterior cruciate ligament (ACL) injury is on the rise. Such injuries may shorten athletes′ career and lead to other long-term adverse consequences. Although athletes generally recover well after ACL reconstruction, many still struggle to return to their pre-injury performance levels. Advances in the understanding of ACL anatomy and injury mechanisms, along with the evolution of surgical techniques and rehabilitation methods, have provided more individualized and tailored options for athletes following ACL injuries. However, there is currently no consensus in China regarding surgical and rehabilitation strategies for competitive athletes aiming to return to sports after ACL injuries. To this end, the Sports Medicine Committee of the Chinese Research Hospital Association and the Editorial Board of the Chinese Journal of Trauma jointly formulated the Expert consensus on surgical treatment and rehabilitation for competitive sports athletes returning to sports after anterior cruciate ligament injury ( version 2025), and presented 14 recommendations covering surgical indications, preoperative rehabilitation, surgical timing, surgical strategies and postoperative rehabilitation strategies, aiming to improve the surgical treatment and rehabilitation system for ACL injuries in competitive athletes and facilitate their return to high-level sports performance after injury.

Abstract Inhibitor of DNA binding 1(ID1) is a crucial regulator of cell differentiation and plays a significant role in maintaining normal hematopoietic differentiation and development. Due to the lack of DNA-binding motif, ID1 functions as a dominant-negative inhibitor of basic helix-loop-helix factors to antagonize their abilities to bind to DNA and transcriptionally regulate target genes. Abnormal expression of ID1 is strongly associated with various hematologic disorders, including myeloid and lymphoblastic leukemia, multiple myeloma and myeloproliferative neoplasms. ID1 acts as a potential oncogene by participating in multiple signaling pathways that promote the malignant proliferation, invasion and therapy resistance in leukemic cells. Significant strides have yielded promising antileukemic effects of ID1 inhibitors, both alone and in combination with targeted therapies against oncogenic signaling pathways. Here, we review the relationship between ID1 expression and the initiation and progression of blood disorders, and summarize the clinical significance of ID1 as a novel therapeutic target and potential prognostic biomarker for hematologic malignancies.

The term yin excess originated in the Huang Di Nei Jing, which refers to the phenomenon of "heavy yin" when wind pathogens invades the human body and defensive qi enters the yin part of the human body. Later doctors have played a role in yin excess. Theoretically, yin and yang are out of balance in the human body, and yin is too much and yang is not enough, which is the process of physiological transformation to pathology; from the diagnosis point of view, patients with yin deficiency have less pulse and more blood; from the clinical manifestations, patients with yin excess appear cold from the back, hands and feet cold reverse; from the point of view of treatment, bitter cold products can cause yin excess. Modern research specifies yin as phlegm, dampness, stasis and other pathological products, and emphasize the relation between yin excess and yang deficiency. Yin excess includes pathological factors such as phlegm stasis cold, external cold straight in the liver wood, set in the hypochasm, resulting in mass; or overthinking and cold drink injury spleen, phlegm turbidiousness, long and hard phlegm forming lumps, thus resulting yin excess; or it may deplete the yang energy of the heart, leading to neglect of the warming function and stagnation of blood stasis; or if the kidney yang is deficient and the body lacks warmth, and there is no true yang in the ridge, then the wood will sink and congest blood stasis; the above etiology and pathogenesis lead to the occupation of yin pathogens, resulting in liver cancer. The treatment methods include liver cold turbidizing, warming liver and dispelling cold, with Wuzhuyu Decoction; spleen-deficiency phlegm production, the treatment should be warm the middle and resolving the phlegm, with Linggui Zhugan Decoction and Zhenwu Decoction; Yang deficiency and stasis, the treatment should warm kidney to remove blood stasis, with Poyu Decoction.

The patient was a boy aged 1 year and 9 months who presented with 46,XY disorder of sex development (DSD), with severe undermasculinization of the external genitalia. Laboratory tests and ultrasound examinations showed normal functions of Leydig cells and Sertoli cells in the testes. Genetic testing revealed a novel pathogenic heterozygous variant, c.1186dupA (p.T396Nfs*17), in the PPP1R12A gene. Thirteen cases of PPP1R12A gene variants have been reported previously. These variants may cause isolated involvement of the genitourinary or neurological systems, or affect other systems/organs including the digestive tract, eyes, heart, etc. Patients with DSD typically present with a 46,XY karyotype and variable degrees of undermasculinization involving the external genitalia, gonads, and reproductive tract. This article reports a child with 46,XY DSD accompanied by growth retardation caused by a heterozygous variant in the PPP1R12A gene, which expands the clinical disease spectrum associated with PPP1R12A gene variants.

BACKGROUND: Double-stranded RNA-specific adenosine deaminase 1 (ADAR1) binds to double-stranded RNA and catalyzes the deamination of adenosine (A) to inosine (I). The functional mechanism of ADAR1 in non-small cell lung cancer (NSCLC) remains incompletely understood. This study aimed to investigate the prognostic significance of ADAR1 in NSCLC and to elucidate its potential role in regulating tumor cell proliferation and migration. METHODS: Data from The Cancer Genome Atlas (TCGA) and cBioPortal were analyzed to assess the correlation between high ADAR1 expression and clinicopathological features as well as prognosis in lung cancer. We performed Western blot (WB), cell proliferation assays, Transwell invasion/migration assays, and nude mouse xenograft modeling to examine the phenotypic changes and molecular mechanisms induced by ADAR1 knockdown. Furthermore, the ADAR1 p150 overexpression model was utilized to validate the proposed mechanism. RESULTS: ADAR1 expression was significantly elevated in lung adenocarcinoma (LUAD) and lung squamous cell carcinoma (LUSC) tissues compared with adjacent non-tumor tissues (LUAD: P=3.70×10-15, LUSC: P=0.016). High ADAR1 expression was associated with poor prognosis (LUAD: P=2.03×10-2, LUSC: P=2.81×10-2) and distant metastasis (P=0.003). Gene Set Enrichment Analysis (GSEA) indicated that elevated ADAR1 was associated with mitogen-activated protein kinase/extracellular signal-regulated kinase (MAPK/ERK) pathway activation, matrix metalloproteinase-9 (MMP-9) expression, and cell adhesion. ADAR1 and MMP-9 levels showed a strongly positive correlation (P=6.45×10-34) in 10 lung cancer cell lines, highest in H1581. Knockdown of ADAR1 in H1581 cells induced a rounded cellular morphology with reduced pseudopodia. Concomitantly, it suppressed cell proliferation, invasion, migration, and in vivo tumorigenesis. It also suppressed ERK phosphorylation and downregulated cellular Finkel-Biskis-Jinkins murine osteosarcoma viral oncogene homolog (c-FOS), MMP-9, N-cadherin, and Vimentin. Conversely, ADAR1 p150 overexpression in PC9 cells enhanced ERK phosphorylation and increased c-FOS and MMP-9 expression. CONCLUSIONS High ADAR1 expression is closely associated with poor prognosis and distant metastasis in NSCLC patients. Mechanistically, ADAR1 may promote proliferation, invasion, migration, and tumorigenesis in lung cancer cells via the ERK/c-FOS/MMP-9 axis.

Objective: To understand the prevalence and related factors of depressive symptoms among primary and secondary school students in the in depth monitoring counties of China s Rural Compulsory Education Nutrition Improvement Program, so as to provide a basis for prevention and psychological intervention of depressive symptoms among children and adolescents in rural areas. Methods: In November 2022, a stratified random sampling method was adopted to collect height and weight data, basic personal and family information of 7 949 primary and secondary school students from grade three to grade nine through physical measurements and questionnaires in 56 key monitoring schools implementing the Student Nutrition Improvement Program in 7 in depth monitoring counties (Jalaid Banner in Inner Mongolia, Jinzhai County in Anhui, Mao Xian in Sichuan, Tiandeng County in Guangxi, Mian County in Shaanxi, Zhaozhou County in Heilongjiang and Youxi County in Fujian), and to obtain the information related to their depressive symptoms through the self assessment questionnaire on depression. Multivariate Logistic regression analysis was conducted to analyze the prevalence of depressive symptoms among primary and secondary school students, as well as their related factors. Results: The detection rate of depressive symptoms among primary and secondary school students in the in depth monitored counties was 23.5%. Logistic regression analysis showed that the probability of detecting depressive symptoms was higher among female students, middle school students, students whose video screen duration per day was >2 h, and students whose parents marital status was divorced or widowed ( OR =1.40, 1.64, 1.60, 1.24), and students whose sleep duration reached the recommended standard, whose parents usually accompanied them daily for time was 60-<120 min and ≥120 min, and students whose mothers literacy level was middle school graduation had lower probability of detecting depressive symptoms ( OR =0.85, 0.84, 0.71, 0.76) ( P < 0.05 ). Conclusion The detection rate of depressive symptoms among students in the in depth monitoring area is high, and targeted interventions need to be developed for students to reduce the risk of mental health problems.
