OBJECTIVE:To explore the effects of ursodeoxycholic acid and adenosine methionine combined with polyene phos-phatidylcholine on related indicators of pregnancy with intrahepatic cholestasis(ICP). METHODS:Medical information of 90 ICP female were analyzed retrospectively and divided into control group(45 cases)and observation group(45 cases)according to drug use. Control group was given Ursodeoxycholic acid tablet 300 mg orally,3 times a day+Transmetil for injection 1 g added into 5%Glucose injection 250 mL intravenously,once a day. Observation group was additionally given Polyene phosphatidylcholine injec-tion 15 mL added into 5% Glucose injection 250 mL intravenously,once a day,on the basis of control group. Treatment course of 2 groups lasted for 2 weeks. The itching score,the levels of serum total bile acid(TBA),ALT and AST,pregnancy outcome and the occurrence of ADR were observed in 2 groups before and after treatment. RESULTS:Before treatment,there was no statistical significance in itching score,the levels of TBA,ALT and AST between 2 groups (P>0.05). After treatment,itching score,the levels of TBA,ALT and AST in 2 groups were significantly lower than before treatment,and the observation group was significant-ly lower than the control group,with statistical significance (P<0.05). The cesarean section rate,premature birth rate,fetal dis-tress rate and amniotic fluid rate of observation group were significantly lower than those of control group,with statistical signifi-cance(P<0.05). No obvious ADR was found in 2 groups during treatment. CONCLUSIONS:Ursodeoxycholic acid,ademetionine combined with polyene phosphatidylcholine can effectively alleviate itching symptoms,liver function and pregnancy outcome of ICP patients,with good safety.

Objective To investigate the urinary iodine level and thyroid function during different trimesters of pregnancy in Hangzhou residents and to provide evidence for monitoring iodine nutrition or screening thyroid function. Methods The urinary iodine level and thyroid function of 395 subjects from 5 hospitals in Hanzhou were investigated. The urinary iodine level was measured by arsenic-cerium contact process method. The serum TSH, FT3 and FT4 were measured by chemiluminescence method. Results (1) The urinary iodine median concentration during pregnancy in the 1st, 2nd and 3rd trimesters were 170.3, 170.2, 162.4 μ/L respectively, all significantly lower than that of non-pregnant women (251.9 μg/L, all P < 0.05); (2) The mean value of TSH during the 1st trimester of pregnancy was significantly lower than that of non-preguant women (P < 0.05). The mean values of FT4 and FT3 in the 2nd and the 3rd trimesters of pregnancy were significantly lower than those of the control (P < 0.05); (3) During 2nd trimester, there were 8.7% (9/104, in FT4) and 9.6% (10/104, in FT3) pregnant women below normal lower range while during 3rd trimester, these figures reached 22.7% (22/97) and 17.5% (17/97) resfectively. Conclusions More than half of the pregnant women in Hangzhou have good nutritional status of iodine. There are significant differences in thyroid hormone levels between the non-pregnant and pregnant women as well as between gestation periods. Therefore, it is necessary to establish a trimester-specific reference range of thyroid hormones for normal pregnancy. The screening for thyroid function is recommended for pregnant women besides monitoring routine urinary iodine.

Objective:To investigate the application of multiscale low-rank plus sparsity (MLRS) modeling in fast ultra-high-field intracranial 4D Flow imaging.Methods:Ten healthy volunteers, 5 males and 5 females, aged 23-35 (29±4) years old, recruited from October 2022 to January 2023 at Huashan Hospital of Fudan University, were prospectively collected. A MLRS model acceleration algorithm was proposed according to the characteristics of 4D Flow data based on the multiscale low-rank (MLR) model. Firstly, full sampling brain 4D Flow scans were performed on healthy volunteers using 7.0 T MR, and the acquired data were under-sampled with Gaussian distributions at different acceleration rates (R of 4, 8, 12, and 16, respectively). The root mean square error (RMSE) and peak signal-to-noise ratio (PSNR) of the compressed sensing algorithm (CS), low-rank plus sparse algorithm (L+S), MLR, and MLRS model were calculated at different acceleration rates, with fully sampled data as reference. And the comparison of models was performed using the paired-samples t-test or Wilcoxon signed rank test. Pearson′s test was used to assess the correlation between hemodynamic parameters of the 4 algorithms and the fully sampled reference values at different acceleration rates, and the correlation coefficients were compared using Wilcoxon signed rank test. Results:The RMSE under the same acceleration rates was MLRS, MLR, L+S, and CS models in ascending order, and the RMSE of the MLRS model was significantly lower than that of the MLR, L+S, and CS models ( P<0.05); the PSNR was MLRS, MLR, L+S, and CS models in descending order, and the PSNR of the MLRS model was significantly higher than that of the MLR, L+S, and CS model ( P<0.05). The correlation coefficients between the blood flow velocity measured by the MLRS model and the reference value were significantly higher than those of the MLR, L+S, and CS models for different acceleration rates ( P<0.05). Conclusion:The proposed MLRS algorithm is capable of accelerating ultra-high-field 4D Flow MR imaging of the brain while guaranteeing the image quality, and the MLRS model has higher reconstruction accuracy compared with conventional acceleration models at the same acceleration rate.

Objective:To determine whether the transepidermal water loss rate (TEWL) is correlated with the stratum corneum (SC) hydration level.Methods:Healthy children aged ≤ 17 years were enrolled from Medical Center for Public Health of Puning, 2 kindergartens and 2 primary schools, from October 2021 to June 2022. TEWL and SC hydration levels were measured on the left forearm and right anterior shank using a device for measuring skin physiological funcitons. Pearson correlation analysis was used to determine the correlations between TEWL and SC hydration levels in children of different ages and genders.Results:A total of 1 396 healthy children were enrolled, aged from 1 month to 17 years. Among them, 783 were male children and 613 were female children. In children aged 1 to < 12 months, no correlation was observed between TEWL and SC hydration levels on the forearms of male children, while TEWL was positively correlated with SC hydration levels on the anterior shanks of male children, as well as on the forearm and anterior shanks of female children ( r = 0.283, 0.404, 0.420, respectively, all P < 0.05) . In children aged 1 to 2 years, positive correlations were observed between the above two indicators on the anterior shanks of male children and forearms of female children ( r = 0.370, 0.419, respectively, both P < 0.01) , while there were no correlations between the two indicators on the anterior shanks of female children or forearms of male children. Positive correlations were observed between TEWL and SC hydration levels on both the forearms and anterior shanks of female children and the forearms of male children aged 3 to 5 years and 6 to 11 years ( r values ranging from 0.172 to 0.293, all P < 0.05) , but not on the anterior shanks of male children aged from 6 to 11 years. The group aged 12 to 17 years exhibited significantly positive correlations between TEWL and SC hydration levels on both the anterior shanks and forearms of male and female children ( r values ranging from 0.269 to 0.485, all P < 0.001) . Conclusion:SC hydration levels are positively correlated with TEWL on the anterior shanks and forearms of healthy children, and the degree of correlation tends to increase with age.
