Objective:To analyze the utilization and tendency of oral hypoglycemic agents in some hospitals of Wuhan from 2010 to 2012. Methods:The relative data of oral hypoglycemic agents used in 32 hospitals of Wuhan area during 2010-2012 were analyzed using consumption sum, DDDs and defined daily dose as the indices. Results:The consumption sum of oral hypoglycemic agents was increased year after year;acarbose and gliclazide were widely used and occupied front places among the drugs. However, the percent-age of traditional Chinese medicine used for decreasing blood sugar was declined. Conclusion:During 2010-2012, the DDDs value and the consumption sum of oral hypoglycemic agents in Wuhan area are stable and normal, and the application will be further developed.

ObjectiveTo explore the role of peripheral blood intermediate monocytes in the pathogenesis of preeclampsia.MethodsFifty-two patients with established preeclampsia in Binhai County People's Hospital from October 2014 to October 2015, 42 healthy pregnant women and 42 healthy non-pregnant women were enrolled in this study. The percentage of intermediate monocyte subsets, ratio of positive cells and mean fluorescence intensity (MFI) of Toll-like receptor (TLR) 2, TLR4, CD64, and triggering receptor expressed on myeloid cell-1(TREM-1), and MFI of intracellular tumor necrosis factor-α (TNF-α) and interleukin (IL)-6 were evaluated by flow cytometry. The concentrations of IL-6, IL-8, IL-1β, IL-12P70 and TNF-α in serum were analyzed using Luminex liquid phase chip technology. Independent two samplest-test, analysis of variance, Mann-WhitneyU test, Kruskal-Wallis test and Pearson correlation analysis were used for statistical analysis.ResultsPercentage of intermediate monocytes was higher in preeclampsia patients [10.4%(5.3%-19.9%)]than in healthy pregnant women [6.6%(4.9%-7.8%)], and both were higher than in non-pregnant women [3.8%(2.4%-5.0)%](allP<0.05). The ratio of TLR4 and CD64 positive intermediate monocytes [(60.1±12.5)%vs (24.9±8.8)%; (85.3±5.4)% vs (67.4±7.5)%](t were 15.416 and 13.437, bothP<0.05), and MFI of TLR4 (50.3±10.2 vs 26.8±8.6), TREM-1(35.6±4.1 vs 28.6±4.7) and CD64 (39.8±5.2 vs 28.9±4.8) (t were 11.898, 7.707 and 10.454, allP<0.05) were higher in preeclampsia patients than in healthy pregnant women. MFI of intracellular IL-6 (32.3±4.7 vs 28.6±3.5) and TNF-α (44.6±6.3 vs 36.7±8.3) in intermediate monocytes of preeclampsia patients was also significantly higher than that of healthy pregnant women (t were 4.239 and 5.245, bothP<0.05). Serum concentrations of IL-6, IL-8 and TNF-α were higher in preeclamptic patients than in healthy pregnant women and non-pregnant women (allP<0.05). Furthermore, a positive correlation was found between the percentage of intermediate monocytes and the serum levels of IL-6 and TNF-α in preeclamptic patients (r were 0.397 and 0.347, bothP<0.05).ConclusionsMonocyte subpopulations from preeclamptic patients are abnormally skewed toward intermediate monocytes which have high expressions of TLR4, TREM-1 and CD64, and secret more proinflammatory cytokines such as IL-6 and TNF-α. Therefore, intermediate monocytes are specifically altered in preeclamptic patients and may play a role in the pathophysiology of preeclampsia.

Objective:To investigate the effect of CD 8+ CD 25+ FoxP3 + regulatory T cell (Treg) expression levels in peripheral blood of pregnant women with premature rupture of fetal membranes(PROM) on immune function of helper T cells (Th) 1/Th2. Methods:Thirty cases of pregnant women with PROM (PROM group), 30 cases of normal pregnant women (normal pregnancy group) and 30 cases of normal non-pregnant women (non-pregnancy group) who treated in Binhai County People′s Hospital from September 2019 to May 2020 were collected. Peripheral blood of each group was collected and the proportion of CD 8+ CD 25+ FoxP3 + Treg was determined by flow cytometry. Peripheral blood mononuclear cells (PBMCs) were extracted and FoxP3 mRNA was determined by polymerase chain reaction (PCR). The levels of Th1-related cytokines interferon-γ (IFN-γ), interleukin (IL)-2, and Th2-related cytokines IL-10 and IL-4 were measured by Luminex liquid phase microarray. The effects of CD 8+ CD 25+ FoxP3 + Tregexpression on Th1/Th2 balance were analyzed. Results:The proportion of CD 8+ CD 25+ FoxP3 + Tregand the expression of FoxP3 mRNA in PROM groupand normal pregnancy group were lower than those in non-pregnancy group: (0.15 ± 0.03) %, (0.35 ± 0.09) % vs. (0.47 ± 0.11) %; 0.89 ± 0.11, 3.15 ± 0.67 vs. 3.75 ± 0.23 , the proportion of CD 8+ CD 25+ FoxP3 + Treg and the expression of FoxP3 mRNA in PROM groupwere lower than those in the normal pregnancy group , and the differences were statistically significant ( P<0.05). The levels of Th1-related cytokines IFN-γ and IL-2 in PROM group and normal pregnancy group were higher than those in non-pregnancy group, the level of Th2-related cytokines IL-4 was lower than that in non-pregnancy group , the levels of IFN-γ and IL-2 in PROM group were higher than those in normal pregnancy group, the level of IL-4 was lower than that in normal pregnancy group , and the differences were statistically significant ( P<0.05). In PROM group, the proportion of CD 8+ CD 25+ FoxP3 + Treg and the expression of FoxP3 mRNA in peripheral blood were negatively correlated with Th1-related cytokines IFN-γ ( r = - 0.413, -0.451, P<0.05) and IL-22 ( r = -0.645, -0.535, P<0.05), and were positively correlated with Th2-related cytokines IL-4 ( r = 0.558, 0.469, P<0.05). Conclusions:The proportion of CD 8+ CD 25+ FoxP3 + Treg in peripheral blood of pregnant women with PROM is lower, and the expression level of related FoxP3 mRNA is lower, which all affecte the Th1/Th2 immune balance and cause Th1 immune drift, which may be the related immune mechanism of PROM.

Objective To investigate the effect of blood glucose levels at admission on the outcomes and hemorrhagic transformation in patients with acute ischemic stroke (AIS) after intravenous thrombolysis. Methods From December 2013 to January 2017, patients with AIS treated with intravenous thrombolysis at the Department of Neurology, Xuzhou Central Hospital were enrolled retrospectively. According to the blood glucose levels on admission, they were divided into non-hyperglycemic group ( ≤8 mmol/L ) and hyperglycemic group ( > 8 mmol/L). The functional outcome was assessed with the modified Rankin Scale score at 90 d after onset, and 0-2 was defined as good outcome and > 2 was defined as poor outcome. From 24 h to 7 d after treatment, CT scan was performed again to determine whether there was intracranial hemorrhage or not. Multivariate logistic regression analysis was used to identify the independent influencing factors of outcomes after intravenous thrombolysis. Results A total of 323 patients with AIS were enrolled, including 237 (73. 4％) in the non-hyperglycemic group and 86 (26. 6％) in the hyperglycemic group; 238 (73. 7％) in the good outcome group, and 85 (26. 3％) in the poor outcome group; 25 (7. 7％) in the hemorrhagic transformation group, and 298 (92. 3％) in the non-hemorrhagic transformation group. Univariate analysis showed that there were significant differences in the proportions of patients with ischemic heart disease, atrial fibrillation, past history of stroke or TIA, as well as age, baseline National Institutes of Health Stroke Scale (NIHSS) score, and baseline blood glucose between the poor outcome group and the good outcome group (all P < 0. 05). There were significant differences in the proportion of hypertensive patients and baseline NIHSS score between the hemorrhagic transformation group and the non- hemorrhagic transformation group ( all P < 0. 05 ). Multivariate logistic regression analysis showed that hyperglycemia at admission (odds ratio [OR] 2. 239, 95％ confidence interval [CI] 1. 210-4. 143; P = 0. 010)and baseline NIHSS score (OR 3. 528, 95％ CI 2. 451-5. 078; P < 0. 001) were the independent influencing factors of poor outcome; hypertension (OR 0. 410, 95％ CI 0. 173-0. 972; P = 0. 043 ) and baseline NIHSS score (OR 2. 283, 95％ CI 1. 382-3. 772, P = 0. 001 ) were the independent influencing factors of hemorrhagic transformation. Conclusion Hyperglycemia at admission was an independent risk factor for poor outcome in patients with AIS after intravenous thrombolytic therapy, but it was not associated with the risk of hemorrhagic transformation.

Analysis of LHQW component profiles in human plasma and urine after repeated therapeutic dosing was conducted using a combination of HRMS and an untargeted data-mining approach, leading to detection of 132 LHQW prototype and metabolite components, which were absorbed

Objective To investigate the prevalence of hepatitis D virus (HDV) infection among patients with chronic hepatitis B virus (HBV) infection in some regions of China. Methods Serum samples were collected from 3 131 patients with chronic HBV infection in 10 provinces, cities, and autonomous regions of China from March 2021 to June 2022, and anti-HDV IgG ELISA was used for the detection of all serum samples. Nested reverse transcription-polymerase chain reaction (nRT-PCR) was used to detect HDV RNA in anti-HDV IgG-positive samples, and the nRT-PCR amplification products of HDV RNA-positive samples were sequenced and analyzed to determine HDV genotype. The clinical features of anti-HDV IgG-positive patients were analyzed. The Mann-Whitney U rank sum test was used for comparison of continuous data between two groups, and the chi-square test or the Fisher's exact test was used for comparison of categorical data between two groups. Results The positive rate of anti-HDV IgG in the 3 131 patients with chronic HBV infection was 0.70% (22/3 131), and that in the patients with chronic HBV infection in Inner Mongolia Autonomous Region, Xinjiang Uygur Autonomous Region, Beijing, and Hunan Province was 1.81% (16/886), 0.88% (2/226), 0.28% (2/708), and 1.00% (2/200), respectively; the patients with chronic HBV infection in Inner Mongolia Autonomous Region had a significantly higher positive rate of anti-HDV IgG than those in Beijing ( P =0.004), and there was no significant difference between the other regions ( P > 0.05). Clinical features of the patients with chronic HBV infection in Inner Mongolia Autonomous Region showed that compared with the anti-HDV IgG-negative group, the anti-HDV IgG-positive group had a significantly higher proportion of patients with Mongol nationality ( P =0.001), abnormal alanine aminotransferase ( P =0.007), or antiviral treatment ( P =0.029), as well as a significantly lower median HBV DNA level ( P =0.030). A total of 19 HDV RNA-positive samples were identified, all of which had HDV genotype 1. Conclusion The prevalence rate of HDV varies greatly across different regions of China, with a higher prevalence rate of HDV in patients with chronic HBV infection from Inner Mongolia Autonomous Region. HDV genotype 1 is the predominant genotype in some provinces and cities of northern China.
