OBJECTIVE: To investigate the detection patterns, clinical phenotypic characteristics, and differences in diagnostic timeliness of Klinefelter syndrome (KS) across prenatal and postnatal stages, with an aim to provide a basis for optimizing strategies for early screening, diagnosis, and intervention. METHODS: A retrospective study was conducted to analyze data from two phases. The prenatal diagnosis group included 33,302 pregnant women who underwent amniocytic karyotyping due to advanced maternal age, abnormal ultrasound findings, or high-risk non-invasive prenatal testing (NIPT). The postnatal diagnosis group included 52,101 patients who underwent peripheral blood karyotyping due to primary infertility, abnormal external genitalia, or growth and developmental abnormalities. Additionally, medical histories of adult diagnosed patients were reviewed retrospectively to identify early occult symptoms. This study was approved by the Medical Ethics Committee of Chengdu Women's and Children's Central Hospital (Ethics No.: LCYJ-2025-030). RESULTS: In the prenatal group, 96 cases of KS were detected (detection rate 0.29%). The primary indications for referral were NIPT indicating sex chromosome abnormalities (45.83%), advanced maternal age (16.66%), and ultrasound abnormalities (17.70%). In the postnatal group, 128 cases of KS were detected (detection rate 0.25%). Clinical presentations were primarily primary infertility/azoospermia (77.34%), and the patients were predominantly adults (84.40%). Retrospective analysis revealed that adult patients presented with specific physical signs that had been overlooked during childhood. CONCLUSION As KS lacks typical early clinical manifestations, diagnosis is often delayed until adulthood when reproductive needs arise, showing a pattern of "passive detection" and resulting in missed opportunities for optimal intervention. By conducting a comparative analysis of prenatal diagnostic data and postnatal retrospective data, a risk association model linking prenatal screening indications with childhood-specific signs was developed. This study has provided empirical evidence for establishing a multidisciplinary, full life-cycle management system of "screening ~ diagnosis ~ monitoring ~ intervention" helping to shift from "passive detection in adulthood" to "proactive management across the entire life course," and laid a foundation for improving early diagnosis rate and long-term quality of life for patients.

Background As one of the primary operational methods in the power grid industry, the insulated glove working method imposes significant physical demands due to the constraints of insulating equipment and specific required postures, resulting in substantial occupational health hazards among workers in this sector, which have garnered widespread social attention. Objective To investigate the prevalence and influencing factors of work-related musculoskeletal disorders (WMSDs) in the neck, shoulder, and lumbar regions among workers wearing insulated gloves, and to provide targeted measures to reduce occupational hazards. Methods Using stratified cluster sampling, 1079 frontline workers were randomly selected from power supply enterprises across 3 provinces in China. The revised Chinese version of the Musculoskeletal Disorders Questionnaire was used to investigate the 1-year prevalence of WMSDs in the neck, shoulder, and lumbar regions among workers wearing insulated gloves, and to collect factors associated with multi-site WMSDs (defined as involvement of ≥2 sites among the neck, shoulder, and lumbar). Results The 1-year prevalence of WMSDs in the neck, shoulder, and lumbar regions was 39.9%, 30.0%, and 25.3%, respectively, with a multi-site WMSDs prevalence of 32.0%. Multiple logistic regression analysis showed that, compared to workers with technical secondary school education or senior high school education and below, workers with junior college education or bachelor’s degrees and above had a higher risk of multi-site WMSDs (OR=2.12, 95%CI: 1.47, 3.06). Compared to workers with <10 years of work experience, those with 10-<20 years of work experience had a higher risk of multi-site WMSDs (OR=1.96, 95%CI: 1.45, 2.67). Working in uncomfortable postures "sometimes" (OR=1.64, 95%CI: 1.14, 2.36), "frequently" (OR=2.75, 95%CI: 1.76, 4.29), and "very frequently" (OR=3.55, 95%CI: 2.04, 6.19) were significantly associated with an increased risk of multi-site WMSDs compared to never working in such postures. Frequent repetitive movements of the low back (OR=2.05, 95%CI: 1.48, 2.84) increased the risk of multi-site WMSDs, while sufficient rest time decreased the risk (OR=0.45, 95%CI: 0.34, 0.61). Conclusion The prevalences of single-site and multi-site WMSDs in the neck, shoulder, lumbar regions are relatively high among workers wearing insulated gloves. Factors associated with multi-site WMSDs include 10-<20 years of work experience, junior college education or bachelor’s degrees and above, uncomfortable working postures, frequent repetitive low-back movements, and lack of sufficient rest time.

Background In recent years, the detection rate of thyroid nodules in China's occupational population has shown an upward trend. The prevalence of this disease needs to be taken seriously and targeted measures should be taken to address its influencing factors. Objective To analyze the detection and influencing factors of thyroid nodules among adult male workers in coal mining enterprises in Shanxi Province, and provide a theoretical basis for the prevention of thyroid nodules. Methods A total of 5195 adult male workers from coal mining enterprises who ordered physical examination provided by the Xishan Coal Electricity (Group) Corporation Occupational Disease Prevention and Control Institute in Taiyuan City, Shanxi Province from May 2023 to December 2023 were selected as research subjects. A questionnaire survey, physical examination, ultrasound examination, and biological sample collection and testing were conducted. Thyroid nodules were diagnosed based on ultrasound results, classified and evaluated according to the Chinese-Thyroid Imaging Reporting and Data System (C-TIRADS), and the crude detection rate and standardized detection rate of thyroid nodules in adult male coal mine workers in Shanxi Province wereestimated. Occupational history and occupational exposure information were retrieved from their annual occupational health examination reports provided by the employer. Logistic regression modeling was used to analyze the influencing factors of thyroid nodule. Results A total of 1688 cases of thyroid nodules were detected, with a crude detection rate of 32.49% and an age-standardized detection rate of 31.17%. The cases (constitution ratio) of thyroid nodules by category in the detected cases was as follows: 358 cases (21.21%) were classified as category 2, 1261 cases (74.70%) as category 3, 67 cases (3.97%) as category 4a, and 2 cases (0.12%) as category 4b. The results of logistic regression showed that the duration of exposure to occupational hazards for 11-20 years, 21-30 years, ≥31 years, average monthly working>26 days, and shift work were positively correlated with the detection of thyroid nodules (P<0.05), and the associated ORs (95%CIs) were 1.29 (1.01, 1.65), 1.55 (1.20, 1.99), 1.68 (1.26, 2.55), 1.19 (1.00, 1.40), and 1.15 (1.02, 1.29), respectively. Conclusion The duration of exposure to occupational hazards, average monthly working days, and shift work are influencing factors of thyroid nodules. Intervention measures should be developed based on these influencing factors to prevent the occurrence of thyroid nodules.

Mastitis,as an important disease that endangers the development of the dairy industry,causes huge economic losses to the breeding industry.Staphylococcus aureus is one of the impor-tant pathogenic bacteria that cause mastitis in dairy cows.Previous studies have found that deoxy-cholic acid(DCA)plays an important role in many diseases,but its effect on mastitis has not been reported yet.In order to investigate the effect and mechanism of DCA on Staphylococcus aureus in-duced mouse mastitis,this study constructed a Staphylococcus aureus induced mouse mastitis model,mice were intraperitoneally injected DCA(0.01,0.02,0.03 mg/g),breast tissue were col-lected,and the protective effect and mechanism of DCA on mastitis were evalued.The results showed that DCA dose dependently reduced the pathological damage of mouse breast tissue in-duced by Staphylococcus aureus;DCA inhibited the expression of inflammatory cytokines TNF-α and IL-1β and MPO activity induced by Staphylococcus aureus;DCA significantly reduced the con-centration of MDA and iron ions,while upregulating the expression of GSH and GPX4,indicating that DCA could inhibit ferroptosis induced by Staphylococcus aureus;Western blot results showed that DCA could upregulate TGR5 receptors,thereby inhibiting the NF-κB signaling pathway.The above results indicate that DCA inhibits mastitis by regulating the TGR5-NF-κB signaling pathway to inhibit the inflammatory response and ferroptosis induced by Staphylococcus aureus.

BACKGROUND:Multiple studies and observations have indicated a close relationship between inflammation,metabolites,and osteoporosis.However,it is still unclear whether there is a genetic causal effect between inflammation-related proteins and osteoporosis and whether metabolites play a mediating role in this process.OBJECTIVE:To investigate the causal relationships between inflammation-related proteins and osteoporosis using Mendelian randomization method as well as the mediating effect of plasma metabolites in this process.METHODS:Summary data from genome-wide association studies(GWAS)were used,with osteoporosis data sourced from the Fengenn database,and GWAS data on inflammation-related proteins and plasma metabolites obtained from published studies.The inverse-variance weighted method was primarily used to assess the exposure-outcome relationships.Bidirectional Mendelian randomization analyses were used to explore the causal relationships between inflammation-related proteins and osteoporosis,and two-step Mendelian randomization was used to discover potential mediating metabolites.Sensitivity analyses were then performed to further validate the robustness of the results.Cochran's Q test was used to assess heterogeneity,and horizontal pleiotropy was evaluated using the MR-Egger intercept and MR-PRESSO methods.RESULTS AND CONCLUSION:The initial bidirectional Mendelian randomization analysis identified five inflammation-related proteins that showed a positive causal relationship with osteoporosis and no reverse causal relationship.Artemin(odds ratio[OR]=0.895,95%confidence interval[CI]:0.819-0.979,P=0.015)was negatively associated with osteoporosis,whereas chemokine(C-X-C Motif)ligand 1(OR=1.100,95%CI:1.002-1.209,P=0.046),chemokine(C-X-C Motif)ligand 11(OR=1.150,95%CI:1.043-1.268,P=0.005),interleukin 17C(OR=1.087,95%CI:1.004-1.176,P=0.040),and tumor necrosis factor-like weak inducer of apoptosis(OR=1.108,95%CI:1.002-1.226,P=0.046)were positively associated with osteoporosis.Sensitivity analyses indicated no heterogeneity or pleiotropy in these causal effects.Subsequently,we conducted a two-step Mendelian randomization to discover potential mediating metabolites.This study showed that 1-palmitoyl-gpc(16:0)increased the negative effect of Artemin on osteoporosis.5α-androstan-3α,17β-diol monosulfate increased the risk of osteoporosis mediated by chemokine(C-X-C Motif)ligand 1 and chemokine(C-X-C Motif)ligand 11.The ratio of α-ketoglutarate to succinate led to an increased risk of osteoporosis mediated by chemokine(C-X-C Motif)ligand 11 and interleukin-17C.Spermidine and the ratio of proline to trans-4-hydroxyproline contributed to an increased risk of osteoporosis mediated by chemokine(C-X-C Motif)ligand 11.12,13-DiHOME contributed to an increased risk of osteoporosis mediated by interleukin-17C.The sulfate level of piperine metabolite C16H19NO3(3)and adenosine 3',5'-cyclic monophosphate contributed to an increased risk of osteoporosis mediated by tumor necrosis factor-like weak inducer of apoptosis.In conclusion,the above data indicate that some inflammation-related proteins can influence the risk of osteoporosis,both positively and negatively,and some of these effects are mediated by plasma metabolites.This provides new insights for future investigations into the occurrence and development mechanisms of osteoporosis.

Objective To establish an electrical field(EF)stimulation model for Schwann cells(SCs),and to provide a basis for exploring the mechanisms of EF stimulation in promoting proliferation,migration and epithelial-to-mesenchymal transition of SCs.Methods A YC-3 bipolar programmable electrical stimulator and an electrotaxis chamber were used to construct an EF stimulation system to stimulate SCs.In the study,SCs were divided into control group(Ctrl)receiving no EF stimulation and EF group stimulated by continuous constant-voltage EF(100 mV/mm,3 h).The effects of EF stimulation on the proliferation and migration of SCs were analyzed using CCK-8 assay,and wound healing assay+Transwell assay,separately;and its effect on SCs adhesion was observed by analyzing the expressions of E-cadherin and N-cadherin using Western Blot.Results The CCK-8 assay results suggested that the absorbance at 450 nm was significantly higher in EF group than in Ctrl group(P<0.05).The results of wound healing assay+Transwell assay revealed that EF group had higher cell migration efficiency than Ctrl group(P<0.05).Western Blot results showed decreased E-cadherin expression and increased N-cadherin expression in EF group as compared with Ctrl group(P<0.05).Conclusion The improved EF stimulation system for SCs is operable.EF stimulation can promote the proliferation and migration of SCs.The decreased E-cadherin expression and increased N-cadherin expression may be related to the occurrence of epithelial-to-mesenchymal transition in SCs after EF stimulation.

Objective To investigate the association between the TyG index,its modified variants,and the risk of developing colorectal cancer(CRC).Methods This study included a total of 93,177 participants from the 2006 Kailuan Group health examination cohort.Participants were categorized into four quartiles(Q1-Q4)according to their TyG and modified TyG indices.Follow-up began at the baseline examination,with incident CRC as the primary outcome.Participants were censored at the time of CRC diagnosis,death,or the end of the study,whichever occurred first.The dose-response relationship between TyG and its modified indices and the risk of CRC was evalu-ated using restricted cubic splines(RCS)in conjunction with Cox proportional hazards regression models,yielding hazard ratios(HRs)and 95%confidence intervals(CIs).To compare the strength of associations between TyG and its modified versions(TyG-BMI,TyG-WC,TyG-WHR,TyG-WHtR,TyG-WWI)and CRC risk,HRs for CRC per one standard deviation increase in each index were calculated and compared.Results Both the TyG index and its modified variants demonstrated a significant dose-response relationship with the risk of CRC incidence.Specifically,for the TyG index,each 1-standard deviation(SD)increase was associated with a 1.17-fold(95%CI:1.09～1.27)higher risk of CRC.Compared with the first quartile(Q1),the third quartile(Q3)and fourth quartile(Q4)exhibited a 1.25-fold(95%CI:1.01～1.55)and 1.26-fold(95%CI:1.01～1.57)increased risk,respectively.For TyG-BMI,each 1-SD increase was linked to a 1.20-fold(95%CI:1.07～1.35)elevated CRC risk.Compared with Q1,Q3 and Q4 showed a 1.32-fold(95%CI:1.06～1.64)and 1.51-fold(95%CI:1.21～1.88)increase,respectively.Regarding TyG-WC,each 1-SD increment was associated with a 1.22-fold(95%CI:1.13～1.32)higher CRC risk,with Q3 and Q4 showing a 1.35-fold(95%CI:1.08～1.70)and 1.56-fold(95%CI:1.24～1.96)increased risk compared to Q1.For TyG-WHtR,each 1-SD increase was associated with a 1.24-fold(95%CI:1.08-1.42)higher CRC risk.Compared with Q1,Q2,Q3,and Q4 demonstrated a 1.31-fold(95%CI:1.03～1.66),1.55-fold(95%CI:1.23～1.95),and 1.60-fold(95%CI:1.27～2.02)increase,respectively.In the case of TyG-WHR,each 1-SD increase was associated with a 1.19-fold(95%CI:1.10～1.29)higher CRC risk,with Q4 showing a 1.42-fold(95%CI:1.14～1.77)increased risk compared to Q1.Finally,for TyG-WWI,each 1-SD increase was associated with a 1.22-fold(95%CI:1.13～1.32)elevated CRC risk,with both Q3 and Q4 showing a 1.58-fold increase(Q3:95%CI:1.26～1.98;Q4:95%CI:1.25～1.99).Stratified analyses by sex and age consistently revealed significant associations between the TyG index and its modified variants and CRC risk.Furthermore,these indices were independently associated with the incidence of both colon cancer and rectal cancer.Conclusions(1)Elevated levels of the TyG index and its modified variants are independent risk factors for CRC.(2)Both the TyG index and its modified forms demonstrate a significant dose-response association with the incidence of CRC.(3)Among the modified TyG indices,TyG-WWI,TyG-WHtR,TyG-BMI,TyG-WC,and TyG-WHR showed stronger correlations with CRC risk compared to the original TyG index.

Objective To observe the clinical efficacy of Jiawei Sanpian decoction in the treatment of liver stagnation and blood stasis tension-type headache.Methods A total of 87 patients with Liver stagnation and blood stasis tension-type headache who were admitted to Beijing First Hospital of Integrated Chinese and Western Medicine from April 2021 to November 2022,and observation group(n=44)was treated with Jiawei Sanpian decoction granules combined with ibuprofen capsules,and control group(n=43)was treated with Jiawei Sanpian decoction granules simulant combined with ibuprofen capsules for 28 days.Pain visual analogue scale(VAS)score,traditional Chinese medicine(TCM)symptom score and clinical efficiency were compared between the two groups.Results VAS score and TCM symptom score in two groups decreased sigwificamtly after therapy,and VAS score and TCM symptom score in observation group decreased more significantly than these in control group,and the difference was statistically significant(P＜0.05).After therapy,the effective rate of patients in observation group was significantly higher than in control group(P＜0.05).Conclusion Combined with Jiawei Sanpian decoction treatment,it can reduce VAS score of patients with liver stagnation and blood stasis tension-type headache,improve the clinical symptoms of patients,and enhance the clinical effective rate,which is better than Western medicine treatment alone,and is worthy of clinical promotion and application.
