Effects of metformin on peripheral blood Treg/Th17 cells and related cytokines in patients with type 2 diabetes mellitus and influenza A / 中国医师进修杂志

Objective:To explore the effects of metformin on levels of peripheral blood regulatory T cells (Treg)/Th17 cells and related cytokines in patients with type 2 diabetes mellitus (T2DM) and influenza A.Methods:A total of 108 patients with T2DM and influenza A treated in Zhejiang Veteran Hospital were prospectively enrolled between April 2021 to April 2022. According to different medication methods, they were divided into observation group (54 cases, oseltamivir + metformin) and control group (54 cases, oseltamivir + gliclazide). The average usage time and dosage of oseltamivir, concentration of blood lactate and blood gas level, counts of Th17 and Treg cells, and levels of related cytokines in the two groups were compared before and after treatment.Results:The average usage time and dosage of oseltamivir, and concentration of blood lactate were higher in observation group than control group: (8.94 ± 0.88) d vs. (7.23 ± 0.79) d, (1.32 ± 0.15) g vs. (1.08 ± 0.11) g, (1.83 ± 0.43) mmol/L vs. (1.61 ± 0.32) mmol/L, P<0.05. The differences in pH, partial pressure of arterial oxygen (PaO 2) and partial pressure of arterial carbon dioxide (PaCO 2) between the two groups had no statistically significant before and after treatment ( P>0.05). After treatment, the differences in count of Treg cells, interleukin-10 (IL-10), interleukin-4 (IL-4), CD 3+, CD 4+ and CD 4+/CD 8+ between the observation group and the control group were statistically significant: (35.48 ± 5.64)% vs. (42.53 ± 6.17)%, (30.49 ± 4.72) ng/L vs. (35.64 ± 5.08) ng/L, (32.15 ± 3.06) ng/L vs. (35.33 ± 3.12) ng/L, (61.39 ± 3.28) % vs. (66.27 ± 3.05)%, (34.12 ± 1.93)% vs. (36.59 ± 2.61)%, 1.26 ± 0.34 vs. 1.52 ± 0.41, P<0.05. After treatment, the count of Th17 cells, Th17/Treg, interleukin-17 (IL-17) and γ-interferon (IFN-γ) in the observation group were higher than those in the control group:(8.69 ± 1.42)% vs. (7.94 ± 2.03)%, 0.24 ± 0.06 vs. 0.19 ± 0.05, (17.67 ± 3.11) ng/L vs. (12.18 ± 3.42) ng/L, (287.48 ± 45.12) ng/L vs. (254.27 ± 41.09) ng/L, P<0.05. During treatment, the difference in incidences of adverse reactions between the two groups had no statistically significant ( P>0.05). Conclusions:Oseltamivir combined with metformin can recover the balance of Th17/Treg cells in patients with T2DM and influenza A to a certain extent. Clinically, level of blood lactate should be monitored.

Exposure to famine in fetus and infant period and risk for hypertension in adulthood / 中华流行病学杂志

Objective@#To investigate the relationship between exposure to famine in fetus and infant period and the risks for hypertension in adulthood.@*Methods@#A total of 5 960 participants born between 1956 and 1965 were included in the study and were divided into unexposed group (1963-1965), fetal exposed group (1959-1961), early- childhood exposed group (1956-1958) and transitional group (1962). Logistic regression model was used to explore the association between famine exposure in early life and the risk for hypertension in adulthood.@*Results@#Both the fetal exposure and the early-childhood exposure were the risk factors for hypertension in adulthood (OR=1.249, 95%CI: 1.049-1.486 and OR=1.360, 95%CI: 1.102-1.679). Meanwhile, in rural area, compared with unexposed group, the fetal exposure (OR=1.401, 95%CI: 1.091-1.798) and the early-childhood exposure (OR=1.460, 95%CI: 1.145-1.862) were also associated with a greater risk of hypertension in adulthood. In addition, fetal exposure and early-childhood exposure to famine in women were associated with 36.0% and 31.9% increased risks for hypertension (95%CI: 7.8%-71.7% and 95%CI: 4.8%-66.0%) according to the stratified analysis.@*Conclusion@#Fetal exposure to famine might increase the risk for hypertension in adulthood.

Association between PLA2G4C minisatellite polymorphism and schizophrenia / 吉林大学学报(医学版)

Objective To investigate the association between the minisatellite polymorphism in the first exon of PLA2G4C gene and schizophrenia, and to reveal the important role of DNA sequence polymorphism in the pathogenesis of schizophrenia.Methods The minisatellite polymorphisms in the first exon of PLA2G4C gene in 91 patients with schizophrenia (case group)and 81 healthy persons (control group)were detected with PCR-sequencing analysis.The chi-square (χ2 )goodness-of-fit test was used to analyze the distribution of the PLA2G4C minisatellite polymorphism in various groups and to explore the association between the minisatellite polymorphism in the first exon of PLA2G4C gene and schizophrenia. Results There were minisatellite polymorphisms in PLA2G4C gene.Three kinds of polymorphisms 1×27 bp,2×27 bp and 3×27 bp were found by sequencing.The distribution of allelic frequencies at PLA2G4C polymorphism showed no statistical significance between case group and control group (P>0.05 ). No statistically significant difference was found in 3-homozygous haplotypes in PLA2G4C gene between case group and control group (P>0.05).At the same time,there was no statistically significant difference between 3-heterozygous haplotypes in PLA2G4C gene between case group and control group (P>0.05).Conclusion The minisatellite polymorphisms in the first exon of PLA2G4C gene are found,but the minisatellite polymorphism in the first exon of PLA2G4C gene may be not associated with the occurrence of schizophrenia.

Meta-analysis on inherited association between 5-hydroxytryptamine 2A receptor gene polymorphism and schizophrenia / 吉林大学学报(医学版)

Objective To investigate the association between 5-hydroxytryptamine 2A receptor (HTR2A)gene T102C locus polymorphism and schizophrenia,and to provide basis for evidence-based medicine for the genetic background of schizophrenia.Methods PubMed,EMbase,CNKI,WanFang and Vip information databases were used to search full text of all the relevant studies about the association between HTR2A gene T102C locus polymorphism and schizophrenia,which were published during 2003 to 2012.Based on reviewing full text,the data were selected, evaluated and accessed. RevMan 5.1 and Stata 1 2.0 were used to perform the statistical analysis of those studies that were in accordance with the inclusive criteria. According to the different ethnicities, the obj ects were divided into two subgroups as European and Asian to analyze respectively. Also, depending on different inheritances, the obj ects were divided into five patterns including C/T allele, CC/TT, CC/CT+TT, CC+CT/TT and CC+ TT/CT genotypes to analyze respectively, including heterogeneity inspection, effect consoliating and publication bias assessment. Results A total of 11 studies were available for this analysis, including 2 443 schizophrenia patients and 2 469 controls.The Meta-analysis results showed that the allele of all people were OR=1.12,95%CI=0.96-1.31,P>0.05;CC/TT of all people were OR=1.11,95%CI=0.80-1.53,P>0.05;CC/CT+TT of all people were OR=1.13,95%CI=0.99-1.30,P>0.05;CC+CT/TT of all people were OR=1.18, 95%CI=0.93-1.50,P>0.05;CC+TT/CT of all people were OR=0.95, 95%CI=0.84-1.06,P>0.05.Conclusion Current evidence is insufficient to show that HTR2A gene T102C locus polymorphism may be associated with schizophrenia, suggesting that the gene polymorphism has no significantly genetic association with schizophrenia.
