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.

AIM:To prepare radix scutellariae mi-croemulsion gel and investigate its therapeutic ef-fect on chronic eczema based on the previous re-search of radix scutellariae self microemulsion.METHODS:The gel matrix and humectant were op-timized by single factor method and response sur-face method to obtain the formula and preparation technique of the gel.The Franz diffusion cell meth-od was used to evaluate the transdermal proper-ties of microemulsion and microemulsion gel in vi-tro.By establishing a chronic eczema model in the mouse ear,the swelling degree,swelling inhibition rate,pathological changes and tumor necrosis fac-tor a(TNF-a),Interleukin-1β(IL-1β)and interleukin-6(IL-6)of radix scutellariae microemulsion gel were measured,to investigate the therapeutic ef-fect on chronic eczema in mice.RESULTS:The physi-cal and chemical properties of radix scutellariae mi-croemulsion gel were stable.Compared with micro-emulsion,the microemulsion gel had better trans-dermal performance.The cumulative transdermal amount of baicalein and wogonin,the main compo-nents of microemulsion gel,was 1.85 times and 2.77 times of that of microemulsion respectively.Moreover,the steady flow rate and permeability co-efficient of microemulsion gel significantly in-creased,and the lag time significantly shortened.Pharmacodynamic study showed that compared with the model group,the radix scutellariae micro-emulsion gel could significantly reduce the ear swelling of mice(P＜0.05),and the serum inflamma-tory factor TNF-a,IL-1β and IL-6 reduced content by over 37％.Compared with the radix scutellaria aqueous extract and aqueous extract gel,the treat-ment of chronic eczema was better.CONCLUSION:The preparation process of radix scutellaria micro-emulsion gel is feasible,with strong transdermal property,and a significant therapeutic effect on chronic eczema.

Objective To investigate the effect of salvianolic acid B on the antioxidant stress capacity of human umbilical cord mesenchymal stem cells(HUCMSCs)and to improve the clinical application efficiency of mesenchymal stem cells.Methods The 5th generation HUMSCs were used for the experiment and divided into control group,model group,and experimental-L,-M,-H groups.The control group was cultured normally;the model group was treated with 800 μmol·L-1 hydrogen peroxide(H2 O2)for 2 h;and the experimental-L,-M,-H groups were pretreated with 2,10,20 μg·mL-1salvianolic acid B for 24 h before adding 800 μmol·L-1 H2 O2 for 2 h.The levels of glutathione(GSH),superoxide dismutase(SOD),and malondialdehyde(MDA)in the cell supernatant of each group were detected using test kits;real-time fluorescence quantitative reverse transcription polymerase chain reaction was used to detect the mRNA expression of apoptosis-related genes Caspase 1,and B-cell lymphoma-2(Bcl-2).Results After treatment with 800 μmol·L-1H2 O2 for 2 h,the levels of MDA in the cell supernatants of the control group,model group,and experimental-H group were(3.27±0.41),(6.50±0.21)and(4.79±0.40)nmol·mL-1,respectively;the GSH levels were(35.43±0.72),(20.13±0.58)and(32.30±3.87)μmoL·L-1;the SOD levels were(5.34±0.18),(3.34±0.20)and(5.09±0.15)U·mL-1;the expression of Caspase 1 mRNA were 1.02±0.21,2.78±0.26 and 2.37±0.32;the expression of Bcl-2 mRNA were 1.01±0.12,0.43±0.03 and 0.60±0.17.Compared with the control group,the above indexes in the model group were statistically significant(P＜0.05,P＜0.01).Compared with the model group,the above indexes in the experimental-H group were statistically significant(P＜0.05,P＜0.01).Conclusion Salvianolic acid B can reduce apoptosis caused by oxidative stress and enhance the antioxidant stress capacity of HUCMSCs.
