Thyroid B-ultrasound and urinary iodine content were examined in 4390 male workers aged 18-62 years-old,who participated annual physical checkups in 2009 and 2010.The results suggest that there is no obvious relationship between the urinary iodine which represents the iodine intake within 24 hours and prevalence of thyroidnodale.However,the prevalence of thyroid nodules shows an upward trend with the advance of age.

Objective:To explore the risk factors of diabetic nephropathy(DN).Methods:From January 2016 to September 2019, the clinical data of 403 patients with type 2 diabetes in the Integrated Traditional Chinese and Western Medicine Hospital of Wenzhou were analyzed retrospectively.Excluding other factors, they were divided into DM group (315 cases) and DN group(88 cases) according to whether or not they were complicated with DN.The age, course of disease, complications, monocyte to high-density lipoprotein cholesterol ratio(MHR) and other test data were included in the logistic regression model to analyze the independent risk factors of DN.Results:There were statistically significant differences in the course of ≥10 years[95 cases(30.16%) vs.37 cases(42.05%)], complicated with hypertension[141 cases(44.76%) vs.58 cases(65.91%)], insulin application[94 cases(29.84%) vs.39 cases(44.32%)], ACEI/ARB application[132 cases(41.90%) vs.62 cases(70.45%)], FBG[(7.38±2.45)mmol/L vs.(8.26±2.06)mmol/L], HbA1c≥7%[91 cases(28.89%) vs.36 cases(40.91%)], MHR[(10.30±4.38) vs.(17.10±7.18)] and HDL-C[(0.58±0.16)mmol/L vs.(0.52±0.17)mmol/L] between the two groups( t=4.41, 13.31, 6.52, 22.46, 3.08, 4.60, 11.02, 2.65, all P<0.05). Multivariate logistic regression analysis showed that hypertension( OR=2.06, 95% CI=1.36-2.76), HbA1c≥7%( OR=1.32, 95% CI=1.04-1.60), MHR≥11.78( OR=1.65, 95% CI=1.03-2.67) were independent risk factors for DN. Conclusion:Hypertension, HbA1c ≥7%, MHR ≥11.78 are independently correlated with DN, which provide a basis for clinical prognosis.

Objective:To explore the relationship between sex hormone binding globulin and glycolipid metabolism in patients with obese polycystic ovary syndrome.Methods:From April 2016 to April 2019, 114 patients with obese polycystic ovary syndrome in the Integrated Chinese and Western Medicine Hospital of Wenzhou were selected and divided into two groups according to the level of sex hormone binding globulin, including 66 cases in the low level group and 48 cases in the normal group.The blood glucose, blood lipid and sex hormone levels of the two groups were measured and the results were analyzed.Results:The levels of TC, TG, LDL-C and ApoB in the low level group[(2.32±0.97)mmol/L, (6.45±1.25)mmol/L, (3.57±1.01)mmol/L, (0.93±0.32)g/L] were significantly higher than those in the normal group[(1.87±0.89)mmol/L, (4.88±0.94)mmol/L, (3.12±0.88)mmol/L, (0.76±0.17)g/L]( t=2.477-7.322, all P<0.05). The level of ApoA in the low level group[(1.22±0.34)g/L] was significantly lower than that in the normal group[(1.58±0.47)g/L]( t=-4.748, P<0.05), while there was no statistically significant difference in HDL-C between the two groups[(1.45±0.31)mmol/L vs.(1.43±0.56)mmol/L, t=0.244, P>0.05]. The levels of FPG, HbA1C and FINS in the low level group[(5.53±1.45)mmol/L, (6.42±0.79)% and (18.71±5.46)mU/L] were significantly higher than those in the normal group[(5.09±0.76)mmol/L, (6.01±0.92)% and (15.49±4.98)mU/L]( t=2.136-3.225, all P<0.05), while there was no statistically significant difference in 2hPG between the two groups[(8.79±1.56)mmol/L vs.(8.32±1.84)mmol/L]( t=1.472, P>0.05). The incidence of insulin resistance in the low level group[54.55%(36/66)] was significantly higher than that in the normal group[35.42%(17/48)](χ 2=4.088, P<0.05). The level of T in the low level group[(61.45±21.44)ng/mL] was significantly higher than that in the normal group[(50.39±22.31)ng/mL]( t=2.673, P<0.05), while there were no statistically significant differences in FSH, LH, E 2 and PRL between the two groups( t=0.427-1.714, all P>0.05). Conclusion:The patients with low levels of sex hormone binding globulin are more likely to suffer from hyperglycemia and hyperlipidemia, and low levels of sex hormone binding globulin may be a risk factor for obese polycystic ovary syndrome.

Objective: To understand trends and related factors influencing overweight and obesity among primary and secondary school students in Tianjin, so as to provide a basis for formulating overweight and obesity prevention and control strategies. Methods: In September of each year from 2019 to 2023, a survey was conducted among 197 707 primary and secondary school students in 16 districts of Tianjin through a stratified random cluster sampling method. Physical examination was carried out in accordance with the Technical Standard for Physical examination for Student, and overweight and obesity survey was carried out. Basic information, smoking, drinking, diet, physical exercise, and sleep status were collected through questionnaire surveys. Results: The detection rates of overweight and obesity among primary and secondary school students in Tianjin from 2019 to 2023 were 39.07%, 43.33%, 41.54%, 43.92%, and 40.24%, respectively，showing an increasing trend(χ2trend=7.96,P<0.01). The detection rates of overweight increased in both vocational high schools and suburban counties (χ2trends=9.08, 47.18, P<0.01). The detection rates of obesity increased among both male and female students, in primary and vocational high schools and suburban counties (χ2trends=108.34, 15.99, 7.32, 10.95, 14.75, P<0.01). Multivariate Logistic regression analysis showed that smoking, drinking, unhealthful diet, and lack of proper physical exercise had a higher risk of obesity among primary and secondary school students (OR=1.26, 1.13, 1.08, 1.21, P<0.05). Stratified analysis showed that the risk of obesity was higher among boys with unhealthful and moderate lifestyle habits, as well as primary school students with unhealthful lifestyle habits (OR=1.15, 1.11, 1.27, P<0.05). Boys, girls and primary school students with unhealthful lifestyle habits, girls and ordinary high school students with moderate lifestyle habits had higher risk of being overweight (OR=1.14, 1.32, 1.21, 1.18, 1.40, P<0.05). Conclusions The detection rates of overweight and obesity among primary and secondary school students in Tianjin shows an increasing trend. Comprehensive lifestyle should be implemented to better prevent and control the risk of overweight and obesity.

In this study, the mobilomes of nine teleost species were annotated by bioinformatics methods. Both of the mobilome size and constitute displayed a significant difference in 9 species of teleost fishes. The species of mobilome content ranking from high to low were zebrafish, medaka, tilapia, coelacanth, platyfish, cod, stickleback, tetradon and fugu. Mobilome content and genome size were positively correlated. The DNA transposons displayed higher diversity and larger variation in teleost (0.50% to 38.37%), was a major determinant of differences in teleost mobilomes, and hAT and Tc/Mariner superfamily were the major DNA transposons in teleost. RNA transposons also exhibited high diversity in teleost, LINE transposons accounted for 0.53% to 5.75% teleost genomic sequences, and 14 superfamilies were detected. L1, L2, RTE and Rex retrotransposons obtained significant amplification. While LTR displayed low amplification in most teleost with less than 2% of genome coverages, except in zebrafish and stickleback, where LTR reachs 5.58% and 2.51% of genome coverages respectively. And 6 LTR superfamilies (Copia, DIRS, ERV, Gypsy, Ngaro and Pao) were detected in the teleost, and Gypsy exhibits obvious amplication among them. While the SINE represents the weakest ampification types in teleost, only within zebrafish and coelacanth, it represents 3.28% and 5.64% of genome coverages, in the other 7 teleost, it occupies less than 1% of genomes, and tRNA, 5S and MIR families of SINE have a certain degree of amplification in some teleosts. This study shows that the teleost display high diversity and large variation of mobilome, there is a strong correlation with the size variations of genomes and mobilome contents in teleost, mobilome is an important factor in determining the teleost genome size.

Estrogen receptor (esr) mediates the effects of estrogen on the expression of related genes, thereby regulating the growth and reproduction of mammals. To investigate the effect of retrotransposon insertion polymorphism (RIP) of the porcine esr gene on porcine growth performance, retrotransposon insertion polymorphism of the esr gene were predicted by comparative genomics and bioinformatics, and PCR was used to verify the insertion polymorphisms in different porcine breeds. Finally, the correlation analysis between the genotypes and performance of Large White pigs was conducted. The results showed that four retrotransposon polymorphic sites were identified in the esr1 and esr2 genes, which are esr1-SINE- RIP1 located in intron 2 of the esr1 gene, esr1-LINE-RIP2 and RIP3-esr1- SINE located in intron 5 of the gene, and esr2-LINE-RIP located in intron 1 of the esr2 gene, respectively. Among them, insertion of a 287 bp of SINE into intron 2 of the esr1 gene significantly affected (P<0.05) the live back fat thickness and 100 kg body weight back fat thickness of Large White pigs. Moreover, the live back fat thickness and back fat thickness at 100 kg body weight of homozygous with insertion (SINE+/+) was significantly greater than that of heterozygous with insertion (SINE+/-) and homozygous without insertion (SINE-/-). Therefore, esr1-SINE-RIP1 could be used as a molecular marker to assist the selection of deposition traits in Large White pigs.
