Objective:To investigate the clinical efficacy of Yunkang oral liquid combined with dexamethasone and low-molecular-weight heparin in the treatment of recurrent spontaneous abortion (RSA) complicated with pre thrombotic state (PTS), and its effects on thromboelastogram and serum progesterone, β-human chorionic gonadotropin (β- hCG), and helper T cell (Th) 1/Th2 cytokine levels in patients with recurrent spontaneous abortion (RSA).Methods:A prospective selection of 94 RSA patients with PTS admitted to the Baoding Second Central Hospital from January 2015 to December 2020 was conducted. They were randomly divided into two groups using a random number table method, with 47 patients in each group. The control group was treated with dexamethasone combined with low molecular weight heparin, while the observation group was treated with Yunkang oral liquid in addition to the control group. Continuously treat until 12 weeks of pregnancy to evaluate the efficacy of both groups and observe the adverse reactions in both groups. Two sets of thromboelastogram parameters were compared before and after treatment, including clot formation time (K value), clot reaction time (R value), and clot formation rate (α angle), maximum clot strength (MA value), and coagulation comprehensive index (CI), as well as serum progesterone β- hCG, Th1/Th2 cytokine levels. The pregnancy outcomes of the two groups were followed up.Results:The total effective rate of the observation group [95.7%(45/47)] was significantly higher than that of the control group [83.0%(39/47), P<0.05]. After treatment, the K and R values of both groups were significantly prolonged compared to before treatment (all P<0.05), the angle α, MA value, and CI value were significantly reduced compared to those before treatment (all P<0.05); After treatment, the K and R values in the observation group were significantly longer than those in the control group (al P<0.05), The angleα, MA value, and CI value were significantly lower than those of the control group (all P<0.05). After treatment, the levels of β- hCG serum progesterone of the two groups were significantly higher than those before treatment (all P<0.05), and The β-hCG levels of the serum progesterone were all higher than those in the control group (all P<0.05). After treatment, The levels serum Th1 cytokines [interferon-γ (INF- γ), tumor necrosis factor- α (TNF- α)] of both groups were significantly decreased compared to those before treatment (all P<0.05), and the levels of serum Th2 cytokines [interleukin-4, IL-10] were significantly increased compared to those before treatment (all P<0.05); After treatment, the observation group's serum IFN- γ, TNF- α were significantly lower than those of the control group (all P<0.05), and The levels of serum IL-4 and IL-10 were significantly higher than those of the control group all P<0.05). The live birth rate of the observation group was 87.2%(41/47), which was higher than that of the control group [70.2%(33/47)] ( P<0.05). There was no statistically significant difference in the adverse reaction rate between the observation group [6.4%(3/47)] and the control group [4.3%(2/47)] ( P>0.05). Conclusions:The treatment of RSA combined with PTS with Yunkang oral liquid, dexmedroxyprogesterone, and low molecular weight heparin can significantly alleviate blood hypercoagulability, increase reproductive endocrine hormone levels, regulate Th1/Th2 cytokine balance, improve live birth rate and clinical efficacy, and is safe and reliable.

Objective:To investigate the clinical efficacy of vitamin D drops combined with insulin aspart in the treatment of gestational diabetes mellitus (GDM), and the effect of vitamin D drops on the serum levels of 1, 25 dihydroxyvitamin D 3 [1, 25(OH) 2D 3] and retinol binding protein 4 (RBP4). Methods:A total of 94 GDM patients admitted to the Baoding Second Central Hospital from March 2019 to March 2021 were selected and randomly divided into an observation group and a control group with 47 cases each using a random number table method. The control group received subcutaneous injection of insulin aspartate for treatment, while the observation group received oral vitamin D drops for treatment. After 4 weeks of continuous treatment, the blood glucose control effect and adverse reactions were observed in both groups. The glucose metabolism indicators of the two groups were compared before and after treatment, including fasting blood glucose (FPG), 2-hour postprandial blood glucose (2-hour PG), insulin resistance index (HOMA-IR), and pancreatic islets β Cell Function Index (HOMA-β) and serum levels of 1, 25(OH) 2D 3, RBP4, lipoprotein related phospholipase A2 (Lp-PLA2), and vascular cell adhesion molecule-1 (VCAM-1). All patients were followed up until the end of pregnancy, and Statistical analysis was conducted on the adverse outcomes of two groups of mothers and infants. Results:The time to reach the standard for FPG and 2-hour PG in the observation group, as well as the time for both to reach the standard were significantly shorter than those in the control group (all P<0.05). There was no statistically significant difference in the incidence of dawn phenomenon and hypoglycemia between the observation group and the control group (all P>0.05). After treatment, FPG and 2-hour PG in both groups were significantly reduced compared to those before treatment (all P<0.05); However, after treatment, there was no statistically significant difference between the groups (all P>0.05). Compared with before treatment, HOMA-IR in both groups significantly decreased (all P<0.05), All HOMA- β significantly increased (all P<0.05); And the improvement was more significant in the observation group (all P<0.05). After treatment, the serum levels of 1, 25(OH) 2D 3 in the observation group significantly increased compared to that before treatment ( P<0.05), but there was no significant change in the control group before and after treatment ( P>0.05). After treatment, the levels of serum RBP4, Lp-PLA2, and VCAM-1 in both groups significantly decreased compared to those before treatment (all P<0.05); After treatment, the serum levels of RBP4, Lp-PLA2, and VCAM-1 in the observation group were lower than those in the control group (all P<0.05). The incidence of adverse maternal and neonatal outcomes in the observation group was 14.9%(7/47) and 10.6%(5/47), respectively, which were lower than those in the control group [34.0%(16/47) and 27.7%(13/47)] (all P<0.05). There were 8 cases of hypoglycemia in 94 patients (3 in the observation group and 5 in the control group), and no other adverse events occurred. Conclusions:The combination of vitamin D drops and insulin aspartate in the treatment of GDM can safely, effectively, quickly, and steadily control patients′ blood sugar, improve IR and pancreatic islets β The effect of cell function on reducing the incidence of adverse maternal and fetal outcomes may be related to increasing serum 1, 25(OH) 2D 3 levels and down-regulating the expression levels of serum RBP4, Lp-PLA2, and VCAM-1.

Objective To investigate the current situation and health effects of indoor microbial pollution in Xi'an, to analyze the purification effect of air purifiers on indoor microbial pollution, and to provide reference for improving the indoor environment. Methods Through stratified random sampling, 20 families from rural areas and 20 families from upwind and downwind urban areas respectively were selected from Xi'an. Data was collected by questionnaire surveys and on-site environmental sampling. Non-parametric analysis and correlation analysis were used for statistical analysis. Results Overall, the standard-exceeding rate of total count of bacteria was 5.00%. The medians of the total count of bacteria and fungi were 312.50 cfu/m3 and 260.00 cfu/m³, respectively. In terms of health effects, the correlation between rhinitis and cold with total bacterial count was statistically significant (P<0.05), with the correlation coefficients of 0.182 and 0.223, respectively. Purification effect of air purifiers on microbial pollution was statistically significant (P<0.05). After opening for 2 hours, the total numbers of bacteria and fungi decreased significantly. Conclusion The occurrence risk of colds and rhinitis is increased by indoor microbial pollution. Air purifiers have a certain effect on decreasing the total number of bacteria and fungi. It is recommended to use air purifiers with high CADR of particulate matter, double-layer filter and sterilization and dehumidification function, and replace the filters regularly to reduce indoor microbiological contamination.
