Objective To investigate the causal relationship between metabolic syndrome and breast cancer by using a bidirectional two-sample Mendelian randomization (MR) approach. Methods Genome-wide association study (GWAS) summary statistics for metabolic syndrome and breast cancer were acquired from the Integrative Epidemiology Unit GWAS database and the GWAS Catalog, with populations encompassing the United States and East Asia. A bidirectional causal design was employed: a forward analysis with metabolic syndrome as the exposure and breast cancer as the outcome, followed by a reverse analysis wherein their roles were interchanged. The inverse-variance weighting (IVW) method was primarily used for effect estimation, supplemented by MR-Egger regression, the weighted median method, the simple mode method, and the weighted mode method. Instrument variable strength was screened using the F-statistic (F>10). Robustness of the results was assessed through heterogeneity tests, horizontal pleiotropy tests, forest plots, and leave-one-out sensitivity analyses. Results The IVW analysis indicated no significant causal relationship between metabolic syndrome and breast cancer (OR=1.00, 95%CI: 0.97-1.03), P>0.05). Sensitivity analyses yielded consistent results, suggesting the good robustness of the study findings. Conclusion This study found no evidence to support a causal relationship, either positive or negative, between metabolic syndrome and breast cancer.

Idiopathic pulmonary fibrosis (IPF), a chronic interstitial lung disease, is characterized by aberrant wound healing, excessive scarring and the formation of myofibroblastic foci. Although the role of alternative splicing (AS) in the pathogenesis of organ fibrosis has garnered increasing attention, its specific contribution to pulmonary fibrosis remains incompletely understood. In this study, we identified an up-regulation of serine/arginine-rich splicing factor 7 (SRSF7) in lung fibroblasts derived from IPF patients and a bleomycin (BLM)-induced mouse model, and further characterized its functional role in both human fetal lung fibroblasts and mice. We demonstrated that enhanced expression of Srsf7 in mice spontaneously induced alveolar collagen accumulation. Mechanistically, we investigated alternative splicing events and revealed that SRSF7 modulates the alternative splicing of pyruvate kinase (PKM), leading to metabolic dysregulation and fibroblast activation. In vivo studies showed that fibroblast-specific knockout of Srsf7 in conditional knockout mice conferred resistance to bleomycin-induced pulmonary fibrosis. Importantly, through drug screening, we identified lomitapide as a novel modulator of SRSF7, which effectively mitigated experimental pulmonary fibrosis. Collectively, our findings elucidate a molecular pathway by which SRSF7 drives fibroblast metabolic dysregulation and propose a potential therapeutic strategy for pulmonary fibrosis.

BACKGROUND:Ligament rupture and defect of the lateral or medial malleolus caused by high-energy injuries are common challenges in foot and ankle surgery.Their neighboring core tendons are often used as grafts to reconstruct the deficient ligaments.It is of paramount importance to investigate the mechanical properties of such tendons in the context of ligament defects to provide a suitable donor tendon.OBJECTIVE:To investigate the interactive dynamics and biomechanical alterations among their core tendons during ankle joint motions under varying degrees of lateral or medial malleolar ligament defect.METHODS:Based on CT imaging data of the left foot of a 50-year-old healthy male,a surface stereolithography model was extracted and constructed using MIMICS software.After Geomagic Wrap software was employed to fit the surfaces,a bone-cartilage-ligament-tendon ankle complex model incorporating varying degrees of ligament deficiencies was created within SOLIDWORKS software.Finite element analysis was then conducted using Ansys Workbench software,and the model's validity was verified through a simulated anterior drawer test.Following validation,the mechanical response of the ankle under the conditions of internal and external rotation,as well as inversion and eversion,was simulated.The variation and distribution patterns of the maximum Von-Mises stress in the peroneus brevis and longus tendons,as well as the anterior and posterior tibial tendons,were observed.RESULTS AND CONCLUSION:(1)In the anterior drawer test,the maximum talar displacement reached 5.208 5 mm,which was similar to the data in the previous literature,thereby the effectiveness of the model was validated.(2)Under four loading conditions,the defect of unilateral single-bundle ligaments exerted minimal influence on the maximum stress of adjacent core tendons,whereas the defect of unilateral multi-bundle ligament significantly increased the maximum tendon stress.Except for the consistently high stress across segments of the anterior tibial tendon,the high-stress regions in the long and short peroneal tendons and posterior tibial tendon were concentrated at their distal ends near the insertions.(3)Regarding the defect of the lateral malleolar ligament,the maximum stress and its variation in the peroneus brevis tendon during inversion and internal rotation were higher than those in the peroneus longus tendon.During inversion under the condition of the defect of the anterior talofibular ligament,the maximum stress in the short peroneal tendon increased by 0.951 2 MPa compared to that of normal condition,while that in the long peroneal tendon decreased by 0.065 1 MPa.Under the condition of the defect of the calcaneofibular ligament during internal rotation,the maximum stress in the short peroneal tendon increased by 2.352 9 MPa,while the maximum stress in the long peroneal tendon decreased by 0.269 2 MPa.(4)During eversion and external rotation under the defect of medial malleolar ligament,the variations in the maximum stress of the anterior and posterior tibial tendons were complex and depended on the type of ligament defect.Notably,full-thickness ligament defect significantly augmented the maximum stress in both tendons.

Objective:To determine the diagnosis of microtia-associated syndrome through genetic testing.Methods:Peripheral venous blood samples were collected from members of a two-generation family with a syndrome associated with ear malformations (3 patients and 1 normal control). Pathogenic mutations were identified using whole exome sequencing analysis, Sanger sequencing validation, and bioinformatics analysis. Based on the genetic diagnosis and a review of the literatures, the patients′ clinical phenotypes were thoroughly evaluated to confirm the clinical diagnosis.Results:All three patients carried a novel heterozygous insertion mutation (c.1171_1172insGGCC: p.Pro391fs) in the paired box 1 ( PAX1) gene. This mutation showed genotype-phenotype co-segregation within the family and was predicted to be pathogenic. Consequently, the family was diagnosed with autosomal dominant otofaciocervical syndrome 2. The clinical phenotypes of the patients included not only ear malformations and conductive hearing loss but also branchial cleft fistula, preauricular fistula, bilateral facial asymmetry, spinal deformities, and short stature, which were major symptoms of otofaciocervical syndrome 2. Imaging also revealed previously unreported phenotypes, including parotid gland malformation and facial nerve dysplasia. Conclusion:The heterozygous insertion in PAX1 (c.1171_1172insGGCC: p.Pro391fs) found in this family causes otomandibular-cervical syndrome type 2 in an autosomal dominant manner, leading to congenital anomalies affecting external and middle ear, craniofacial region, and spine.

Objective To compare the benefits and drawbacks of primary patch expansion versus pericardial tube right ventricular-pulmonary artery connection in patients diagnosed with pulmonary atresia with ventricular septal defect (PA/VSD). Methods A retrospective study was conducted on patients diagnosed with PA/VSD who underwent primary right ventricular-pulmonary artery connection surgery at our center between 2010 and 2020. Patients were categorized into two groups based on the type of right ventricular-pulmonary artery connection: a pericardial tube group and a patch expansion group. Clinical data and imaging findings were compared between the two groups. Results A total of 51 patients were included in the study, comprising 31 males and 20 females, with a median age of 12.57 (4.57, 49.67) months. The pericardial tube group included 19 patients with a median age of 17.17 (7.33, 49.67) months, while the patch expansion group consisted of 32 patients with a median age of 8.58 (3.57, 52.72) months. In both groups, the diameter of pulmonary artery, McGoon index, and Nakata index significantly increased after treatment (P<0.001). However, the pericardial tube group exhibited a longer extracorporeal circulation time (P<0.001). The reoperation rate was notably high, with 74.51% of patients requiring further surgical intervention, including 26 (81.25%) patients in the patch expansion group and 12 (63.16%) patients in the pericardial tube group. No statistical differences were observed in long-term cure rates or mortality between the two groups (P>0.005). Conclusion In patients with PA/VSD, both patch expansion and pericardial tube right ventricular-pulmonary artery connection serve as effective initial palliative treatment strategies that promote pulmonary vessel development and provide a favorable foundation for subsequent radical operations. However, compared to the pericardial tube approach, the patch expansion technique is simpler to perform and preserves some intrinsic potential for pulmonary artery development, making it the preferred procedure.

Shengyutang is a famous classical formula of tonic, which is made from Siwutang with Ginseng Radix et Rhizoma and Astragali Radix. It is included in the Catalogue of Ancient Famous Classical Formulas(The First Batch). Based on the Principles of Key Information Research of Ancient Famous Classical Formulas, this paper used bibliometrics to sort out and research the key information of Shengyutang in the aspects of history, composition, origin and processing, dosage, decocting method, efficacy and indications. After research, it has been found that this formula was first recorded in Lanshi Micang written by LI Dongyuan during the Jin dynasty, composed of Rehmanniae Radix, Rehmanniae Radix Praeparata, Chuanxiong Rhizoma, Ginseng Radix et Rhizoma, Astragali Radix and Angelicae Sinensis taproot. The name of the formula passed down through generations was relatively unified, with clear origins and veins. In later generations, this formula was the mainstream, and adjustments were made to the dosage and composition according to the indication. In the formula, Astragalus membranaceus var. mongholicus was selected as the origin of Astragali Radix, and the origins of other medicinal materials were consistent with the 2020 edition of Chinese Pharmacopoeia. Except for Rehmanniae Radix Praeparata, the other medicinal materials were made from raw products, and the dosage form was boiled powder. According to the measurement standard in the Jin dynasty, the recommended usage and dosage were 1.24 g of Rehmanniae Radix, Rehmanniae Radix Praeparata, Chuanxiong Rhizoma, Ginseng Radix et Rhizoma each, 2.07 g of Astragali Radix and Angelicae Sinensis taproot each, crushed into coarse particles that pass through the 4 mesh sieve but can't pass through the 10 mesh sieve, added 1 200 mL of water and boiled to 300 mL, and removed the residue. Shengyutang has the functions of tonifying Qi and blood, and blood intake, treating various sores, and restlessness and insomnia caused by excessive blood flow. In ancient times, this formula was widely used in the treatment of surgical sores, gynecological diseases, deficiency syndrome, etc. In modern clinical practice, it is mostly used to treat gynecological, neurological, musculoskeletal, hematological diseases caused by Qi and blood deficiency. In this paper, the key information of Shengyutang was researched by reviewing relevant ancient literature, in order to provide reference for the modern application and development of this formula.
8.Association between mental health and muscle strength among Chinese adolescents aged 13-18
Chinese Journal of School Health 2025;46(9):1232-1236
Objective:
To explore the association between mental health and muscle strength among Chinese adolescents aged 13- 18, providing a theoretical foundation and intervention strategies for mental health promotion.
Methods:
Data were obtained from the 2019 Chinese National Survey on Students Constitution and Health, including 98 631 Chinese adolescents aged 13- 18. Psychological distress was assessed by using the Kessler Psychological Distress Scale (K10), and mental well being was measured with the Warwick-Edinburgh Mental Well being Scale (WEMWBS). Based on the gender and age specific Z scores of various test items [grip strength, standing long jump, pull ups (for males), and sit ups (for females)], muscle strength index (MSI) was constructed to evaluate the comprehensive level of muscle strength in adolescents. According to the Dual factor Model (DFM) of mental health, participants were categorized into four groups:troubled, symptomatic but content, vulnerable, and complete mental health. Gender differences were analyzed by using Chi-square tests, trends were tested with Cochran-Armitage tests, and multinomial Logistic regression models were applied to assess associations between muscle strength and mental health among adolescents.
Results:
In 2019, 37.4% of Chinese adolescents aged 13-18 were reported of high mental distress, and 59.9% were reported of low mental well being. Boys had significantly lower rates of high mental distress (35.3%) and low mental well being (55.6%) compared to girls (39.4%, 64.3%), and the differences were of statistical significance ( χ 2=176.13, 780.42, both P <0.05). In 2019, the rate of complete mental health among adolescents showed a downward trend with increasing age ( χ 2 trend = 258.47) and a gradual upward trend with increasing muscle strength levels ( χ 2 trend =123.14),and both boys and girls exhibited similar trends ( χ 2 trend =103.83, 168.46; 57.00 , 67.34) (all P <0.05). The results of the unordered multiclass Logistic regression model showed that after controlling for confounding factors such as age and gender, when the completely pathological group as a reference, for every 1 unit increase in MSI in adolescents, the likelihood of being in a completely mental health state increased by 29% ( OR = 1.29); for every unit increase in the Z-score for pull ups, the likelihood of being in a completely mental health state increased by 6% ( OR =1.06) among boys; for every 1 unit increase in sit up Z score, the likelihood of being in a completely mental health state increased by 19% ( OR =1.19) among girls (all P <0.05).
Conclusions
The mental health status of Chinese adolescents is not good enough. Muscle strength is positively associated with mental health.

OBJECTIVE:
To reveal the gap between the evidence of systematic reviews (SRs) and clinical concerns by systematically summarizing the evidence on acupuncture and moxibustion for frozen shoulder and investigating the concerns and needs of clinicians in treatment with acupuncture and moxibustion for this disease.
METHODS:
The articles of SR and Meta-analysis on acupuncture and moxibustion for frozen shoulder were searched from CNKI, Wanfang, VIP, SinoMed, PubMed, EMbase and Cochrane Library, starting from the inception of each database up to December 31st, 2022. Two researchers screened the articles and extracted data independently. Using AMSTAR-2, the methodological quality of the included studies was evaluated. Based on systematic reviews and expert discussion, a questionnaire on clinical concerns of acupuncture and moxibustion for frozen shoulder was developed and distributed to clinicians. The discrepancies between the evidence and clinical concerns were compared from 5 dimensions, including population, interventions, control measures, outcome indicators and review time points.
RESULTS:
The evidence gaps existed between SRs and clinical concerns. In the existing studies, the needs of personalized treatment were not fully considered in terms of different syndromes/patterns of frozen shoulder and stages of illness, the outcome indicators were not employed properly, the time for outcome measurement was vague, the control groups were set up outside of standardization, and the methodological quality was lower.
CONCLUSION
It is suggested that future studies should improve the quality of methodology, lay more consideration to different patient groups, optimize outcome indicators and standardize the setting of control groups, so as to better meet the needs of patients and achieve the best match between evidence and clinicians' needs.

Nucleotide-binding oligomerization domain (NOD)-like receptor protein 3 (NLRP3) is a cytosolic pattern recognition receptor that recognizes multiple pathogen-associated molecular patterns and damage-associated molecular patterns. It is a cytoplasmic immune factor that responds to cellular stress signals, and it is usually activated after infection or inflammation, forming an NLRP3 inflammasome to protect the body. Aberrant NLRP3 inflammasome activation is reportedly associated with some inflammatory diseases and metabolic diseases. Recently, there have been mounting indications that NLRP3 inflammasomes play an important role in liver injuries caused by a variety of diseases, specifically hepatic ischemia/reperfusion injury, hepatitis, and liver failure. Herein, we summarize new research pertaining to NLRP3 inflammasomes in hepatic injury, hepatitis, and liver failure. The review addresses the potential mechanisms of action of the NLRP3 inflammasome, and its regulation in these liver diseases.
