Objective To investigate the prevalence of thyroid diseases in women within 20-week gestation,and to discuss necessity of thyroid diseases screening in women within 20-week gestation.Methods 4986 singleton pregnant women performing prenatal examination in the Maternity and Child Health Care Hospital of Huzhou were recruited into this study.TSH,FT4,and TPOAb levels were detected with ABBOTT ARCHITECT i4000SR.Results ① The median value of TSH rised,the median value of FT4 went down with increase of the gestational weeks.There was significant difference of median value of TSH and FT4 between early and second trimester of pregnancy(P＜0.01).② Rate of abnormal thyroid function was 12.88％,which was higher in the sec ond trimester of pregnancy than that in early pregnancy,and the difference had statistical significance (P＜0.05).③ Positive rate of TPOAb in pregnant women was 11.41％.TPOAb levels were positively correlated with TSH,and no correlation with FT.TSH levels were negatively correlated with FT4.Prevalance of clinical hypothyroidism and subclinical hypothyroidism in TPOAb positive group was significantly higher than that in TPOAb negative group,and the difference had significant difference (P＜0.05).Conclusions Prevalence of thyroid diseases during pregnancy is high.TPOAb is a risk factor and important predictor for hypothyroidism during pregnancy.It is very necessary to perform thyroid diseases screening for pregnant women as early as possible to ensure safety of pregnant women and their babies.

Abstract: Objective　To investigate the frequency of peripheral blood T cells among patients positive for both hepatitis B virus surface antigen (HBsAg) and surface antibody (HBsAb). Methods　 Thirty six patients with co-existence of HBsAg and HBsAb diagnosed were enrolled as the experimental group, who were admitted by Shanghai tenth people's hospital and Wuxi 9th people's hospital from 2014 to 2020. while 40 patients tested positive for HBsAg and negative for HBsAb served as controls, who were admitted by Wuxi 9th people's hospital. Flow cytometry was used to detect and compare the proportions of peripheral blood CD3+, CD4+ and CD8+ T cells between the experimental and control groups. In addition, the associations of serum HBsAb level with peripheral blood T cell proportions, serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels were examined among chronic hepatitis B patients with co-existence of HBsAg and HBsAb using Pearson correlation analysis. Results　The median age, gender distribution, mean ALT and AST concentrations, proportion of HBV DNA viral load>103 copies/mL, seroprevalence of HBV E antigen (HBeAg), seroprevalence of HBV E antibody (HBeAb), seroprevalence of HBV core antibody (HBcAb) were comparable between the experimental and control groups, and there were no significant difference in them (P>0.05). There were no significant difference between the experimental and control groups in terms of CD3+ T cell proportion [(71.83±1.50)% vs (72.75±1.47)%; t=0.66, P>0.05], CD4+ T cell proportion [(36.81±1.53)% vs (39.88±1.57)%; t=1.43, P>0.05] and CD8+ T cell proportion [(33.17±2.04)% vs (32.40±1.75)%; t=0.77, P>0.05]. Pearson correlation analysis revealed that the serum HBsAb level did not significantly correlate with peripheral blood CD3+ (r=0.026, P=0.65), CD4+ (r=‒0.08, P=0.16) and CD8+ T cell proportions (r=0.09, P=0.24), CD4+/CD8+ T proportion (r=‒0.005, P=0.35), serum ALT (r=0.04, P=0.56) and AST levels (r=0.002, P=0.69) among chronic hepatitis B patients with co-existence of HBsAg and HBsAb. Conclusions　There are no significant differences between HBsAg+/HBsAb+ and HBsAg+/HBsAb- CHB patients in terms of peripheral blood CD3+, CD4+ and CD8+ T cell proportions.

AlM: To observe the influence of phacoemulsification combined with intraocular lens implantation on retinal thickness changes of macular center fovea using optical coherence tomography ( OCT) in cataract patients.METHODS: Surgical eyes of 60 cases with cataract were as surgery group, the contralateral eye were as controls group. There was no complication before and during the surgery. Macular thickness was examined by OCT preoperatively and 1wk, 1, 3, and 6mo after surgery. The retinal thickness changes of macular center fovea were compared after surgery. The SPSS 17. 0 software was used for statistical analysis. The paired t-test and variance analysis were used in two groups before and after surgery for relevant statistical data analysis (α=0. 05).RESULTS: ln surgery group, the retinal thickness changes of macular center fovea at 1wk, 1, 3mo after treatment had significant differences compared with preoperation (P<0. 05). The retinal thickness changes of macular center fovea at 6mo after treatment had no statistical significance compared with preoperation ( P>0. 05). The retinal thickness changes of macular center fovea was significantly higher than other groups at 1mo after treatment (P<0. 05). The center fovea appeared to be abnormally thickened in 12 eyes, including 10 eyes of single fovea thickening and 2 eyes of cystoid macular edema in 2~4wk following surgery. Eleven eyes of them were resolved till 6mo postoperatively. ln control group, preoperation or after operation for 1wk, 1, 3, and 6mo respectively, P values were without statistical differences ( P > 0. 05 ). There were no statistical significant differences on retinal thickness of macular center fovea between two groups before and 6mo after surgery ( P>0. 05), while there were significant differences at 1wk, 1 and 3mo after surgery (P<0. 05) CONCLUSlON: The retinal thickness changes of macular center fovea increases significantly after phacoemulsification combined with intraocular lens implantation. ln a few of cases appear macular edema, but the majority of patients can be restored, prognosis is good.

OBJECTIVE: In vivo study on the oxybutynin hydrochloride (OXB) ethosomal gel in rabbits was carried out to obtain pharmacokinetic parameters in comparison to contrast gel. METHODS: After transdermal administration in rabbits of the OXB ethosomal gel and contrast gel respectively, OXB in the plasma was determined by HPLC-MS, the pharmacokinetic parameters were calculated with DAS 2.1.1.
