Correlation between metabolic syndrome and hyperuricemia in perimenopausal women / 中华内分泌代谢杂志

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.

Effect of CXC chemokine receptor 7 on cell cycle of neuronal cells in ischemic stroke / 中华危重病急救医学

Objective:To investigate the function and mechanism of CXC chemokine receptor 7 (CXCR7) in neuronal cells of ischemic stroke.Methods:The expression of CXCR7 in human neuroblastoma SH-SY5Y cells was interfered by small interfering RNA (si-RNA) technique. Oxygen-glucose deprivation/reoxygenation (OGD/R) injury model was constructed in SH-SY5Y cells. CXCR7 protein expression and cell cycle were detected by flow cytometry (FCM). The protein expression of CXCR7 and Akt signaling pathway was detected by Western blotting.Results:After 6 hours of OGD/R, the expression of CXCR7 was significantly decreased compared with OGD/R 0 hour (CXCR7/GAPDH: 0.483±0.098 vs. 1.000±0.000 by Western blotting and 0.686±0.0524 vs. 1.000±0.000 by FCM, both P < 0.01), cell cycle arrest in G0/G1 phase (1.190±0.040 vs. 1.000±0.000, P < 0.01). After CXCR7 si-RNA interference with SH-SY5Y cells, OGD/R was constructed again for 6 hours. Compared with negative control group (si-NC group) under the same environment, the expression of CXCR7 and phosphorylated Akt (p-Akt) was significantly decreased (CXCR7/GAPDH: 0.471±0.051 vs. 1.000±0.000, p-Akt/GAPDH: 0.616±0.027 vs. 1.000±0.000, both P < 0.001) and cell cycle arrest in G0/G1 phase (1.105±0.033 vs. 1.000±0.000, P < 0.05). Conclusion:The CXCR7 could regulate the cycle of neuronal cells in ischemic stroke through Akt signaling pathway, which has a protective effect on neuronal cells.

Detection rate of hypertension in elderly patients of Deang nationality and multilevel model of its influencing factors / 中华老年心脑血管病杂志

Objective To study the influencing factors of primary hypertension by investigating its prevalence in elderly patients of Deang nationality.Methods Nine hundred and thirty-nine elderly patients of Deang nationality were divided into hypertension group (n =353),prehypertension group (n=377) and control group (n=209).Their physical examination data were recorded and their blood pressure was measured.Results The detection rate of hypertension was significantly lower in elderly patients of Deang nationality than in those of the other nationalities in our country with their age ≥60 years (37.6％ vs 49.0％,P＜0.05).The detection rate of hypertension,isolated systolic hypertension and prehypertension increased with the increasing age (P＜0.05).Multivariate logistic regression analysis showed a cross interaction between economic level and alcohol drinking (P＜0.05) and a positive correlation of BMI,age,gender,divorce or widow,smonking,high salt diet with hypertension (P＜0.05).Conclusion The detection rate of hypertension is lower in elderly patients of Deang nationality than in those of the other nationalities in our country.Economic level,alcohol drinking,BMI,age,gender,divorce or widow,smoking,high salt and fat diet are the major risk factors for hypertension.However,regular eating of vegetables can reduce the risk of hypertension.

Role of heme oxygenase-1 in dachengqitang ameliorating lipopolysaccharide-induced acute lung injury in mice / 中国中药杂志

To explore the role of heme oxygenase (HO)-1 experimental system in dachengqitang (DD) ameliorating ALI induced by lipopolysaccharide (LPS) in mice. Seventy-five male Kunming mice were randomly divided into control group (normal saline was instilled intratracheally(50 microL/per mouse), LPS group (LPS was instilled intratracheally to replicate ALI model), DD + LPS group, DD + LPS + ZnPP (ZnPP, HO-1 specific inhibitor) group and the DD group. Mice were killed at 6 h after administration. Lung indexes were tested; lung histomorphological changes were observed under microscope, and neutrophils (PMN) number and protein content of bronchoalveolar lavage fluid (BALF) were measured; HO-1 mRNA and protein expression in lung tissue were detected by RT-PCR and Western blot. The results showed that intratracheal instillation of LPS in mice can cause significant morphological changes in lung tissue. Both PMN numbers and protein content in BALF were increased. meanwhile the expressions of HO-1 mRNA and protein in lung tissue were increased. Pretreated with DD and then intratracheally instillated LPS coulde ameliorat lung tissue injury, reduced PMN BALF number and protein content, but increase HO-1 mRNA and protein expression in the lung tissue when compared with LPS. HO-1 inhibitor ZnPP coulde inhibite the ameliorative effect of DD. The results suggest that the ameliorative effect of DD on ALI induced by LPS in mice were related with upregulation HO-1 mRNA and protein.
