BACKGROUND: The role of inflammation in the development of gestational diabetes mellitus (GDM) has recently become a focus of research. The systemic immune-inflammation index (SII) and systemic inflammation response index (SIRI), novel indices, reflect the body's chronic immune-inflammatory state. This study aimed to investigate the associations between the SII or SIRI and GDM. METHODS: A prospective birth cohort study was conducted at Beijing Obstetrics and Gynecology Hospital from February 2018 to December 2020, recruiting participants in their first trimester of pregnancy. Baseline SII and SIRI values were derived from routine clinical blood results, calculated as follows: SII = neutrophil (Neut) count × platelet (PLT) count/lymphocyte (Lymph) count, SIRI = Neut count × monocyte (Mono) count/Lymph count, with participants being grouped by quartiles of their SII or SIRI values. Participants were followed up for GDM with a 75-g, 2-h oral glucose tolerance test (OGTT) at 24-28 weeks of gestation using the glucose thresholds of the International Association of Diabetes and Pregnancy Study Groups (IADPSG). Logistic regression was used to analyze the odds ratios (ORs) (95% confidence intervals [CIs]) for the the associations between SII, SIRI, and the risk of GDM. RESULTS: Among the 28,124 women included in the study, the average age was 31.8 ± 3.8 years, and 15.76% (4432/28,124) developed GDM. Higher SII and SIRI quartiles were correlated with increased GDM rates, with rates ranging from 12.26% (862/7031) in the lowest quartile to 20.10% (1413/7031) in the highest quartile for the SII ( Ptrend <0.001) and 11.92-19.31% for the SIRI ( Ptrend <0.001). The ORs (95% CIs) of the second, third, and fourth SII quartiles were 1.09 (0.98-1.21), 1.21 (1.09-1.34), and 1.39 (1.26-1.54), respectively. The SIRI findings paralleled the SII outcomes. For the second through fourth quartiles, the ORs (95% CIs) were 1.24 (1.12-1.38), 1.41 (1.27-1.57), and 1.64 (1.48-1.82), respectively. These associations were maintained in subgroup and sensitivity analyses. CONCLUSION The SII and SIRI are potential independent risk factors contributing to the onset of GDM.

Objective:To investigate the association of time in range(TIR) with the severity of coronary artery disease and acute coronary syndrome in patients with type 2 diabetes mellitus.Methods:A total of 216 patients with type 2 diabetes mellitus and coronary heart disease were recruited and undergone anthropometric and biochemical measurements, continuous glucose monitoring, and calculation of SYNTAX score. TIR was defined as the percentage of time within the glucose range of 3.9-10.0 mmol/L during 24 h. Spearman correlation analysis and multivariate linear regression analysis were used to evaluate the correlation factors of SYNTAX score. Multivariate logistic regression analysis was used to analyze the association of TIR with the severity of coronary artery disease and acute coronary syndrome. Results:Compared with patients with mild coronary artery disease, TIR in patients with moderate to severe coronary artery disease was lower[(69.4±17.3)% vs (60.8±17.8)%, t=3.0, P=0.003], and HbA 1C of patients with moderate to severe coronary artery disease was higher [(9.6±1.7)% vs (8.8±1.6)%, t=3.3, P=0.001]. SYNTAX score was negatively correlated with TIR ( r=-0.251, P<0.01) and positively correlated with HbA 1C ( r=0.249, P<0.01). Moreover, compared with HbA 1C (standardized coefficients=0.181, P=0.007), TIR (standardized coefficients=-0.192, P=0.004) had a greater influence on SYNTAX score. Multivariate linear regression analysis showed that TIR, HbA 1C, duration of diabetes and smoking were independently correlated with SYNTAX score. Multivariate logistic regression analysis revealed that compared with TIR Q1, Q3 and Q4 were independent protective factors for moderate to severe coronary artery disease (respectively, OR=0.61 and 0.59, 95% CI 0.39-0.96 and 0.38-0.94, P=0.014 and 0.009) and acute coronary syndrome (respectively, OR=0.51 and 0.39, 95% CI 0.32-0.95 and 0.26-0.75, P=0.022 and 0.008). Conclusion:TIR was significantly and independently correlated with the severity of coronary artery disease and acute coronary syndrome in type 2 diabetes mellitus after controlling confounding factors. When TIR level was decreased, the severity of coronary artery disease was aggravated, and SYNTAX score and the risk of acute coronary syndrome was increased.

Objective To investigate the effect of astragalus injection combined with beta-adrenoceptor antagonist on serum levels of brain natriuretic peptide ( BNP) , interleukin1β( IL-1β) , IL-6 and tumor necrosis factorα( TNF-α) in the treatment of elderly patients with heart failure. Methods 78 elderly patients with heart failure from April 2013 to April 2015 in department of cardiology of the second hospital of Yuhang district were selected and divided into control group and experimental group with 39 cases in each group.All patients received correction of the electrolyte and acid-base balance and other conventional treatment.The control group received carvedilol by oral, the experimental group received astragalus injection on the basis of control group, with a course of 30 days.The serum BNP,IL-1β,IL-6 and TNF-αlevels pre-and post-treatment in two groups were compared. Results Compared with pre-treatment, the serum IL-1β,IL-6,TNF-α,and BNP levels post-treatment in two groups were lower(P<0.05).Compared with the control group post-treatment, the IL-1β,IL-6,TNF-αand BNP levels in experimental group were lower(P <0.05).Conclusion Astragalus injection combined with beta-adrenoceptor antagonist could significantly improve the clinical sign of elderly patients with heart failure, the mechanism may be reducing the serum levels of IL-1β,IL-6,TNF-αand BNP.
