Summary: This study evaluated the relationship between polymorphisms in the MTHFR gene and CHD in the Gansu region of China. The findings suggest that the TT genotype of the MTHFR C677T locus is closely associated with an increased risk of CHD.

Summary: This study explored the relationship between cognitive impairment after general anesthesia and rs55763075 polymorphisms. Patients with AA genotype showed lower MMSE scores, decreased MTHFR mRNA expression, and reduced MTHFR protein expression compared to patients with GG/GA genotypes. The study also demonstrated that the minor allele (A) of rs55763075 polymorphisms affected the binding of miR-34b to MTHFR mRNA, leading to decreased folic acid levels in AA-genotyped patients.

Summary: The MTHFR 677TT variant, gender, folate, and Vit B12 were identified as risk factors for the occurrence of H-type hypertension. Folate level decreased with the C to T substitution of the MTFHR C677T gene, while Vit B12 level was not associated with the gene. These factors should be considered in the prevention and treatment of hypertension.

Summary: This study examined the influence of the MTHFR C677T variant on BMI and its role as a risk factor for obesity. The results showed that the MTHFR 677TT genotype is not directly related to a higher BMI in Polish adults but has a detrimental effect on folate concentrations in individuals with high BMI values.

Summary: Polycystic ovary syndrome (PCOS) is a reproductive endocrine disease with no specific drug treatment. Quercetin (QUR), a flavonoid, has potential therapeutic effects for PCOS patients. However, the mechanisms of QUR in PCOS patients remain unclear.

Summary: This study investigated the effect of MTHFR gene polymorphism and folic acid supplementation on serum homocysteine levels in psoriatic patients. The results showed that individuals with the TT genotype of MTHFR rs1801133 had higher serum homocysteine levels and better treatment response. Sex and genotype were significantly associated with serum homocysteine levels. Folic acid supplementation only decreased homocysteine levels in male patients.

Summary: This study found that CFDT can alleviate pathological damage and apoptosis in PCOS rat model. In addition, CFDT can improve ovarian function, reduce inflammatory response, inhibit apoptosis of granular cells, and inhibit the operation of ASK1/JNK pathway in PCOS rats.

Summary: PCOS is a common disorder in women of reproductive age, affecting their physiology and metabolism, and often leading to metabolic syndrome and insulin resistance; Berberine can intervene in the development of PCOS in multiple ways, including alleviating insulin resistance, reducing androgen levels, regulating lipid metabolism, and reducing inflammation.

Summary: Polycystic ovary syndrome (PCOS) is the most common endocrine disorder among women of reproductive age. The etiologies of this syndrome are complex and involve prenatal factors, genetic variation, epigenetic mechanisms, unhealthy lifestyles, and environmental toxins. This review examines the molecular mechanisms underlying PCOS pathogenesis at the level of signaling pathways and discusses potential therapies including exosome therapy, gene therapy, and drugs based on traditional Chinese medicine and natural compounds.

Summary: This study investigated the association of methylenetetrahydrofolate reductase (MTHFR) gene polymorphisms with small vessel disease (SVD) risk. The findings revealed that SVD patients had elevated plasma total homocysteine (tHcy) levels and decreased folate levels. Significant differences were observed in the rs1801133 (C677T) gene polymorphism, with higher tHcy levels in individuals carrying the TT allele. The rs1801131 (A1298C) polymorphism was not associated with tHcy levels or SVD risk. Therefore, elevated plasma tHcy levels are closely associated with the development of SVD, while MTHFR gene polymorphisms are not a risk factor for SVD.

Summary: This study aimed to investigate the metabolic characteristics of overweight women with PCOS and analyze the possible mechanisms. The results showed that overweight PCOS patients were prone to hypertension, diabetes, low gonadal levels, and insulin resistance. Inflammatory cytokines CXCL12/SDF-1, Serpin E1/PAI-1, and MIF were predicted to play a crucial role in inducing insulin resistance in overweight PCOS through various biological functions and signal transductions.

Summary: This study evaluated the clinical and biochemical characteristics of patients with type 1 diabetes (T1D) with and without polycystic ovarian syndrome (PCOS). The results showed a prevalence of 39% for PCOS in T1D patients, and significant differences were found between patients with and without PCOS in terms of insulin usage, glucose levels, ovarian volume, and Ferriman-Gallwey scores. Additionally, PCOS women had a higher incidence of insulin resistance and metabolic syndrome.

Summary: Polycystic ovary syndrome (PCOS) is a common endocrine disease in women of childbearing age, causing menstrual disorders and infertility. The pathogenesis of PCOS is complex and not fully understood. Gut microbiota is associated with lipid, glucose, and steroid hormone metabolism disorders. Recent studies have shown that gut microbiota can regulate insulin synthesis and secretion, and affect androgen metabolism and follicle development, providing a new perspective for understanding the pathogenesis of PCOS.

Summary: This study investigated the prevalence of different chronotype categories in women with PCOS and their impact on hormonal and metabolic aspects. The findings showed a higher prevalence of evening chronotype in women with PCOS, which was associated with worse hormonal and metabolic profiles.
