RESUMEN
BACKGROUND: Observational studies have found associations between sex hormones and metabolic syndrome(Mets), but the causal relationships remains unclear. This study utilizes univariable and multivariable Mendelian randomization (MR) to elucidate the associations between sex hormones (including sex hormone-binding globulin(SHBG), estradiol(E2), testosterone(T)) and Mets and its subtypes (including waist circumference(WC), fasting blood glucose(FBG), high blood pressure(HBP), high-density lipoprotein(HDL-C), triglycerides(TG)). METHODS: We utilized summary data from large-scale genome-wide association studies. Univariable Mendelian randomization (UMVMR) analysis was primarily conducted using the inverse variance weighted method (IVW), with secondary analyses employing the weighted median, MR-Egger regression, simple mode method, and weighted mode method. Subsequently, multivariable Mendelian randomization (MVMR) was employed to assess the causal relationships between SHBG, T, E2, and MetS and its components: WC, FPG, HBP, HDL-C, and TG. Sensitivity analyses were conducted to assess result reliability. RESULTS: Genetically predicted SHBG was significantly negatively associated with MetS (UMVMR: ß=-0.72; 95% CI = 0.41 to 0.57; P = 1.28e-17; MVMR: ß=-0.60; 95% CI=-0.83 to -0.38; P < 0.001). Positive causal relationships were observed between SHBG and WC(MVMR: ß = 0.10; 95% CI = 0.03 to 0.17; P = 0.01) and HDL-C (MVMR: ß = 0.41; 95% CI = 0.21 to 0.60; P < 0.001), while negative causal relationships were found between SHBG and HBP (MVMR: ß=-0.02; 95% CI=-0.04 to -0.00; P = 0.02), TG (MVMR: ß=-0.48; 95% CI=-0.70 to -0.26; P < 0.001). Genetically predicted E2 exhibited a negative association with TG (MVMR: ß=-1.49; 95% CI=-2.48 to -0.50; P = 0.003). Genetically predicted T was negatively associated with TG (MVMR: ß=-0.36; 95% CI=-0.71 to -0.00; P = 0.049) and WC (MVMR: ß=-0.13; 95% CI=-0.24 to -0.02; P = 0.02), with inconsistent sensitivity analyses. Additionally, No other causal associations were found. CONCLUSION: Our study indicates that SHBG is a protective factor for MetS, potentially delaying its onset and progression through improvements in HBP and TG. Furthermore, T and E2 may improve TG levels, with T also reducing WC levels. Importantly, our study provides new insights for the prevention and treatment of MetS.
RESUMEN
Osteoporosis is a metabolic bone disease. ß-Catenin is associated with fractures. Jian-Pi-Bu-Shen (JPBS) can promote the healing of osteoporotic fractures (OPF). However, the mechanism of ß-catenin-mediated skeletal muscle satellite cells (SMSCs) in OPF by the JPBS is unclear. SMSCs were isolated and divided into five groups. The results showed that the survival rate of SMSCs was significantly higher in the low, medium, and high dose JPBS-containing serum groups after 7 days of incubation. The ALP activity and the number of SMSCs mineralized in the JPBS-containing serum intervention group were elevated. Axin, GSK-3ß, ß-catenin siRNAs were constructed and transfected into cells. Transfection of siRNAs reduced Axin, GSK-3ß, and ß-catenin expressions, respectively. ß-Catenin-siRNA reversed ALP activity, the number of SMSCs mineralized, and the expression of ß-catenin, BMP2, Runx2, COL-I, SP7/Ostrix, Osteocalcin, and BMP-7. Transcriptomic results suggested that the TNF signaling pathway associated with OPF was enriched. SD rats were subjected to the construction of OPF model by removing the ovaries. JPBS decreased the levels of PINP, ALP, CTX, and NTX through ß-catenin in OPF rats, while increasing Runx2, ß-catenin expressions through ß-catenin at the broken end of fractures. Moreover, JPBS decreased BMC, BMD, and BV/TV and improved pathological damage through ß-catenin in OPF rats. JPBS decreased the expression of Axin, GSK-3ß mRNA, and protein, but increased the expressions of ß-catenin, Pax7, COL-II, COL-II, BMP2, and Runx2 through ß-catenin in OPF rats. In conclusion, JPBS inhibits Axin/GSK-3ß expression, activates the ß-catenin signaling, and promotes the osteogenic differentiation of SMSCs.

BACKGROUND: Acupuncture is relatively popular worldwide, but an unregulated operation can easily lead to infections. The purpose of this report was to analyze a clinical case of surgery combined with the use of antibiotics for the treatment of thoracic vertebral infection by Escherichia coli (E. coli) after acupuncture. CASE SUMMARY: A 63-year-old male was diagnosed with E. coli infection in the thoracic vertebra after acupuncture. His fever and pain did not improve after treatment with broad-spectrum antibiotics for 10 d. Thus, debridement of the infected area and biopsy were decided. The final pathology confirmed the diagnosis of vertebral infection by E. coli. The patient underwent anterior and posterior thoracic vertebral debridement and internal fixation surgery combined with the use of sensitive antibiotics. He had no fever or backache 3 mo postoperatively. CONCLUSION: In this report, we first considered antibiotic treatment for the patient with septic spinal infection, but the effect was not obvious. Interventional surgery was combined with the use of sensitive antibiotics to relieve backache, and good clinical results were achieved. Furthermore, acupuncture practitioners should pay attention to hygienic measures.
