ABSTRACT
Objective:To learn about the iodine nutrition level and its spatial distribution status in key populations in Hubei Province, so as to provide a basis for adjustment of iodine supplementation policy and the realization of scientific and accurate iodine supplementation.Methods:In 2020, a sampling was carried out in Hubei Province according to the "National Iodine Deficiency Disorders Monitoring Plan (2016 Edition)" to monitor the concentration of salt iodine and urinary iodine of key populations (children ages 8 - 10 years old and pregnant women). The spatial distribution of iodine nutrition levels was analyzed by spatial epidemiology.Results:The median salt iodine of 17 263 children's family salt samples was 25.0 mg/kg, and the median urinary iodine (MUI) was 217.0 μg/L. There was significant spatial aggregation in the distribution of urinary iodine level in children at the county level ( Moran's Index = 0.36, P < 0.001). The significant hot spot areas with high urinary iodine level among children were located in Shiyan City and Xiangyang City, while the significant cold spot areas with low urinary iodine level were mainly concentrated in Yichang City. The median salt iodine of 8 618 pregnant women's family salt samples was 25.1 mg/kg, the MUI was 176.3 μg/L. The urinary iodine level among pregnant women at the county level was spatially clustered ( Moran's Index = 0.22, P = 0.003) . The significant hot spot areas with high urinary iodine level among pregnant women were mainly in Enshi Tujia and Miao Autonomous Prefecture, the significant cold spot areas were mainly concentrated in Yichang City. Conclusions:In 2020, the iodine nutrition of children in Hubei Province is at a super appropriate level (200 - 299 μg/L), and the iodine nutrition status of pregnant women is more sensitive, which is close to the lower limit of the appropriate level (150 μg/L). The urinary iodine level of children and pregnant women has significant spatial aggregation at the county level. Targeted intervention will be needed in counties (dictricts) where the urinary iodine level is lower or higher than the normal range, to achieve accurate and scientific iodine supplementation.
ABSTRACT
Objective Aspirin is a non steroidal anti-inflammatory drugs, whether or not which does harm to renal function in the course of using, there is a big debate at home and abroad.In this paper, The aim of this study was to observe the effects of different doses of aspirin on renal function in elderly patients with cardiovascular disease at different ages.MethodsWe Selected a total of 288 patients with cardiovascular disease from January 2014 to March 2016 in Zhejiang Rongjun hospital.There were 288 cases of cardiovascular disease, including 144 cases of normal uric acid, 144 cases with hyperuricemia (including gout).The two groups according to the age of 60 to 70 years, 71 to 80 years old, over 80 years old respectively into three subgroups, each subgroup of 48 cases;Each subgroup was randomly selected without the use of aspirin (0mg/d) and the use of different doses of aspirin (50mg/d, 100mg/d, 150mg/d) for a total of four groups, each which is 12 patients.We detect patients routine blood tests, liver and kidney function, blood urea nitrogen (BUN), blood creatinine (SCR) levels and glomerular filtration rate (GFR) (MDRD) and blood and urine beta 2-microglobulin used aspirin before and used after 6 months and 12 months.ResultsBefore treatment, there were no significant differences in body mass index (BMI), blood pressure, hemoglobin, serum albumin and platelet count between various groups of the same age group.After treatment for 6 and 12 months,Uric acid normal patients and high uric acid patients with 0mg/d, 50mg/d, 100mg/d or 150mg/d dose of aspirin has no statistical difference in BUN, Scr and eGFR, 2-microglobulin Ccr, blood, urine beta 2-microglobulin.ConclusionRegardless of uric acid, different doses of aspirin had no significant effect on renal function in elderly patients with cardiovascular disease, and can be safely used.
ABSTRACT
Objective To observe clinical efficacy of probiotics agents in the prevention and treatment of severe pulmonary infection in elderly patients with antibiotic-associated diarrhea (AAD).Methods 60 cases of elderly patients with severe pulmonary infection (more than or equal to 60 years old) were randomly divided into the treatment group ( 31 cases ) and control group ( 29 cases ) , the control group received broad-spectrum antibiotics or using two linked above anti-infection treatment, the treatment group were added with probiotic agent ( lactobacillus complex capsules).The diarrhea, the use of antibiotics and the stool routine, bacteria before and after 5, 10, 15 days of group were observed.Results After 15 days treatment, the number of Escherichia coli in treatment group was lower than that in control group (P<0.05), the number of Bacterium lacticum and Bifidobacterium bifidum in treatment group were higher than those in control group ( P<0.05 ) .The AAD rate in treatment goup was 12.90%, which was lower than 41.38% in control group (P<0.05).There were significant differences in beginning time and duration of diarrhea between two groups (P<0.05). Conclusion The intestinal probiotics reduced induced by antibiotics in elderly patients with severe pulmonary infection , the probiotics agents could redress intestinal flora imbalance, keep the steady state of intestinal flora, and prevent and cure the antibiotic-associated diarrhea.
ABSTRACT
Objective To explore the regulation and effect factors of arsenic expose and arsenic methylation level, then to provide a reference for study the function of arsenic metabolism in a arsenic poisoning process. Methods A meta-analysis was performed by two researchers. Twenty-five papers satisfying our priori eligibility criteria were included by searching Cochrane library, Pubmed, Springer, Embase and China National Knowledge Infrastructure. Based on the results of heterogeneity, a random or fixed effects model was chosen for the meta-analysis. Results The results showed that the following arsenic metabolites increased (all P<0.01) following arsenic exposure: inorganic arsenic [iAs; standardized mean difference (SMD): 1.07; 95% confidence interval (CI):0.61 - 1.53)], monomethyl arsenic (MMA; SMD: 1.10; 95% CI: 0.81 - 1.40), dimethyl arsenic (DMA; SMD: 2.50;95%CI:1.50-3.69), and total arsenic (TAs, SMD:3.10;95%CI:2.13-4.07). Additionally, the percentages of iAs (iAs%; SMD: 1.00; 95% CI: 0.60 - 1.40) and MMA (MMA%; SMD: 0.49; 95% CI: 0.21 - 0.77) also increased, while the percentage of DMA (DMA%; SMD: - 0.55; 95% CI: - 0.80 - - 0.31) decreased (P<0.01). The primary methylation index (PMI; SMD: - 0.57; 95% CI: - 0.94 - - 0.20), and secondary methylation index (SMI;SMD: - 0.27; 95% CI: - 0.46 - - 0.09) decreased (all P< 0.01). Compared to female, male had higher MMA%(SMD:0.44;95%CI:0.35-0.52), lower DMA%(SMD:-0.33;95%CI:-0.38--0.28) and SMI (SMD:-0.36;95%CI:-0.53--0.19). The smoker had higher MMA%(SMD: 0.22; 95%CI: 0.07 - 0.37) and lower DMA%(SMD:-0.16;95%CI: - 0.26 - - 0.05). The drinker had higher MMA% (SMD: 0.17; 95% CI: 0.07 - 0.27) and lower DMA%(SMD:-0.24;95%CI:-0.39--0.10). The older people had higher MMA%(SMD:-0.23;95%CI:-0.40--0.06). In addition, the body mass index may influence the percentages of MMA (SMD: - 0.18; 95% CI: - 0.31 - - 0.04, P < 0.01). Conclusion Arsenic exposure, smoking, drinking, and older age can reduce the capacity of arsenic methylation. Arsenic methylation is more efficient in women than in men.

ABSTRACT
Objective To investigate the association of lipoprotein lipase gene Hind Ⅲ and S447X polymorphisms with metabolic syndrome. Methods PCR-RFLP was used to detect lipoprotein lipase Hind Ⅲ and S447X genotypes in 401 subjects(including 201 controls, 200 metabolic syndrome patients). Results ( 1 ) The levels of waist circumference ( WC ) , hip circumference ( HC ) , waist-to-hip ratio ( WHR ) , body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure ( DBP) , total cholesterol ( TC) , triglyceride (TG), high-density lipoprotein-cholesterol (HDL-C), low-density lipoprotein-cholesterol (LDL-C), and fasting plasma glucose (FPG) were significantly different between metabolic syndrome group and control group (all P< 0.05). (2)The frequencies of H+H+ genotype,H+allele,SS genotype, and S allele for metabolic syndrome were all significantly higher than those for controls( H+H+ genotype:66. 5% vs 54.2% ,P=0.012; H+ allele:78.0% vs 71.4%, P=0.031;SS genotype:89.5% vs 77. 1% , P = 0.001; Sallel:94.5% vs 87. 56% , P = 0.001). (3) The levels of WC, HC, WHR, BMI, SBP, DBP, TG, LDL-C, and FPG in H + H-/H-H- genotype were significantly lower than those in H+H+ genotype, HDL-C was significantly higher than that in H+H+ genotype ( all P<0. 05). The levels of WC, HC, WHR, BMI, SBP, DBP, TC, TG, and FPG in SX/XX genotype were significantly lower than those in SS genotype, HDL-C was significantly higher than that in SS genotype ( all P< 0.05). (4)Multi-way logistic regression analysis suggested that risk factors for metabolic syndrome were smoking, drinking, and SS genotype (OR value was 4.289,2.268, and 2. 597, respectively ). (5) Result of interaction analysis among different factors indicated that the risk for metabolic syndrome in smoker with SS genotype was 3. 996 times of non-smokers with SX/XX genotype. Conclusions The lipoprotein lipase gene S447X polymorphism is associated with metabolic syndrome risk in Kazakh, and SS genotype and S allele may serve as genetic risk factors of metabolic syndrome, H + H-/H-H- and SX/XX genotypes yield beneficial effect for lipid and blood pressure. SS genotype and smoking may exist additive effect.
