RESUMEN

Objective:To assess the prevalence of metabolic syndrome(MS) and its relationship with hyperuricemia(HUA) in perimenopausal women in Anning city, Yunnan province.Methods:This is a cross-sectional survey. In May 2021, a multi-stage stratified sampling method was used to collect demographics and clinical data [ethnicity, living community, height, weight, waist circumference, blood pressure, fasting plasma glucose, triglycerides(TG), serum uric acid, high density lipoprotein-cholesterol(HDL-C), alanine transaminase(ALT), etc] in a total of 6 721 perimenopausal women aged 45-60 years.Results:A total of 6 721 perimenopausal women were included in this study. The prevalences of MS and HUA were 14.05%(95% CI 13.22%-14.88%) and 6.46%(95% CI 5.88%-7.07%), respectively. The average age, HDL-C, urea, direct bilirubin, and albumin levels in the perimenstrual HUA population were lower than those in the non-HUA population while the levels of TG, ALT, heart rate, body mass index(BMI), and creatinine were higher(all P<0.05). The prevalence of HUA in perimenopausal women with ethnic minorities and family history of chronic diseases was higher than that in Han nationality and without family history of chronic diseases. The prevalence of MS in perimenopausal women was increased with the increase of serum uric acid( Z=-15.313 8, P<0.001). Multivariate logistic regression model showed that HUA was positively correlated with MS( OR=1.526, 95% CI 1.192-1.954) after adjusting for covariates such as BMI and ethnicity, and the incidence of MS in perimenopausal women in HUA group was 1.526 folds higher than that in non-hyperuricemia group. Conclusion:HUA is highly positively correlated with MS in perimenopausal women. The management of uric acid level in perimenopausal women should be strengthened.

RESUMEN

Objective:To study the molecular mechanism for momordin in inducing apoptosis of multidrug-resistant human chronic leukemia K562/A02 cells. Methods:The growth inhibition value of K562/A02 cells was detected by CCK-8 method. Cell apoptosis was analyzed by Annexin Ⅴ flow cytometry (FCM) and cell morphological examination. FCM was also used in determining expression of P-glycoprotein, p53 protein, bcl-2 protein and caspase activity. Results:Momordin inhibited the proliferation of K562/A02 cells in a dose-dependent manner. It also induced cell apoptosis, reduced the expression of P-glycoprotein, p53 protein and bcl-2 protein, and increased caspase-3 and caspase-8 activity.Conclusion:Momordin reversed the inhibition of apoptosis in multidrug-resistant K562/A02 cells. The molecular mechanism may be related with down-regulation of expression of p53 protein, P-glycoprotein, and bcl-2 protein and up-regulation of caspase-3 and caspase-8 activities.

RESUMEN

[Objective] To explore effect of momordin on reversion of multidrug resistance(MDR) in K562/A02 cells,and expression and function of P-glycoprotein(P-gp).[Methods] IC50 was detected by CCK-8,and expression of P-gp and retention of ADM in K562/A02 cells were detected by flow cytometry(FCM).[Results] Momordin can improve sensitivity of K562/A02 cells to many kinds of chemotherapeutical drugs,result in decrease of expression of P-gp,and raise concentration of ADM within cells.[Conclusion] Momordin can partly reverse drug resistance of K562/A02 cells,the mechanism of reversion is related with down regulation of expression of P-gp.
