ABSTRACT
Objective@#To observe the association between puberty development and thyroid function among school-aged girls in Minhang District of Shanghai, in order to explore the effect of puberty development on thyroid function. @*Methods@#The study was based on a cohort of adolescent girls recruited in iodine-suitable areas of Minhang District, and the baseline and follow-up survey have been carried out from January to March 2019. The method of phased cluster sampling was used to select one junior high school in the east, south, north and middle of Minhang District, Shanghai, respectively. Finally, 464 new junior high school girls were included in the Cohort study for physical examination, and girls were followed up from January to March 2021. The Puberty Development Scale (PDS) was used to assess the stage of puberty. Serum thyroid stimulating hormone (TSH), free triiodothyronine (FT3), and free thyroxine (FT4) were determined for each participant. Thyroid homeostasis structure parameters (THSPs) was calculated. Changes of Thyroid hormones at baseline and follow-up were compared by Wilcoxon signed rank sum test. Multiple linear regression analyses were used to evaluate the associations of thyroid hormones (THs) and THSPs changes with pubertal develepment.@*Results@#Serum TSH levels of female studentds decreased significantly, while their FT3 and FT4 levels increased significantly during the study period ( Z=-10.53, -4.71, -12.46, P <0.01). In multiple linear regression analysis after adjustment for co-variables (including baseline age, change of BMI and waist circumference), FT4 and thyroid feedback quantile-based index (TFQI) in the higher puberty category scores changes (△PCS) group were further reduced compared with those in the low △PCS group ( β =-0.66, -0.55 ). Compared to the late puberty at baseline and follow-up (BLFL) group, FT4 and TFQI showed higher decline in the pre-puberty at baseline and late puberty at follow-up (BPFL) group with the pre-puberty at baseline and end of puberty at follow-up (BPFT) group ( β =-0.55, -0.44)( P <0.05). There were no association of △TSH, △FT3, △FT4/FT3 and TSH index changes (△TSHI) with △PCS or the puberty pattern.@*Conclusion@#Serum TSH decreases while serum FT3 and FT4 increase among girls during puberty. Both the initial stage and the velocity of pubertal development are related to thyroid hormone fluctuations.
ABSTRACT
OBJECTIVE To study the nephrotoxicity of the extracts from different parts o f Miao medicine Wikstroemia indica in healthy rats ，and to provide reference for the study of its toxicity mechanism and clinical drug use. METHODS Using 70％ ethanol as solvent ，total ethanol extract of W. indica was extracted with diacolation method. After dispersing the above extract with water，the fractions of corresponding fractions were obtained with petroleum ether ，ethyl acetate and n-butanol，and the rest was the extract of water fraction. SD rats were randomly divided into total ethanol extract group ，petroleum ether fraction group ，ethyl acetate fraction group ，n-butanol fraction group ，water fraction group and blank group ，with 12 rats in each group （half male and half female ）. The rats in the administration groups were given the corresponding dose of drug solution intragastrically （total ethanol extract 317.520 mg/kg，petroleum ether fraction 7.875 mg/kg，ethyl acetate fraction 78.435 mg/kg，n-butanol fraction 53.865 mg/kg and water fraction 76.545 mg/kg），once a day ，for conse- cutive 2 weeks，and then stopped taking drug for 2 weeks； rats in the blank group were given equal volume of 1.0％ . sodium carboxymethyl cellulose solution intragastrically. Duringthe experiment ，the general conditions of rats were observed. The samples of urine （on the 14th and 28th day ），serum and bilateral renal tissues （on the 15th and 29th day ）were taken respectively，the renal index was calculated ，the levels of @qq.com renal function indexes in serum and urine were detected ，and the pathomorphological changes of renal tissues were observed. RESULTS During administration ，compared with blank group ，the rats in the total ethanol extract group and ethyl acetate fraction group showed poisoning behavior and activity characteristics such as mental depression ，decreased activity and diet ，thin stool and decreased body mass. The mental state of the rats in the petroleum ether fraction group ，n-butanol fraction group and water fraction group were slightly worse than that in blank group，and slightly decreased activity and diet as well as thin stool ，and slowly increased body mass were found ；however，there was no significant difference in anal temperature in each group. After 2 weeks of administration ，the renal index in total ethanol extract group ，the serum levels of N-acetylglucosaminidase（NAG），urea nitrogen （BUN）and creatinine （Cr）in total ethanol extract group and ethyl acetate fraction group ，serum level of NAG in n-butanol fraction group and serum level of Cr in water fraction group ，as while as NAG levels in urine of rats in total ethanol extract group and petroleum ether fraction group ，NAG and urinary protein levels in urine of rats in ethyl acetate fraction group were increased significantly （P＜0.05 or P＜0.01）. In the pathomorphological observation ，renal tubules showed different degrees of unclear structure ，cell swelling and a few cell necrosis in the total ethanol extract group ，petroleum ether fraction group and ethyl acetate fraction group ，accompanying by glomerular pyknosis，renal tubular sclerosis and inflammatory cell infiltration ，compared with blank group. After drug withdrawal ，the mental state of rats in the administration groups were significantly improved ，the amount of activity and diet increased ，and the stool tended to be normal. Two weeks after drug withdrawal and recovery ，the levels of above indexes in serum and urine of rats in administration groups returned to be close to that in blank group （P＞0.05）；the glomerular structure of rats in each administration group gradually recovered clearly ，and cell swelling and inflammatory cell infiltration were rare in total ethanol extract group ， petroleum ether fraction group and ethyl acetate fraction group. CONCLUSIONS The total ethanol extract ，petroleum ether fraction and ethyl acetate fraction of Miao medicine W. indica have certain nephrotoxicity and reversibility. The toxic component may
