Objective To study the levothyroxine doses and related factors in the treatment of pregnant women with subclinical hypothyroidism (SCH).Methods Fifty-six pregnant women with SCH (diagnosed before 12 weeks of gestation) were recruited and divided into 2 groups according to the baseline TSH levels,SCH group 1 (2.5 mIU/L ≤ TSH ≤ 5.0 mIU/L,n =24) and SCH group 2 (TSH>5.0 mIU/L,n =32).Thyroid autoantibodies [thyroid peroxidase antibody(TPOAb) and thyroglobulin antibody(TGAb)] were detected.All the subjects were treated with levothyroxine and the doses were adjusted according to the TSH level.The therapeutic target was to keep the TSH levels under control,0.3 to 2.5 mIU/L for the first trimester and 0.3 to 3.0 mIU/L for the second and third trimesters.Results There was a positive correlation between the levothyroxine doses and baseline TSH levels (r =0.533,P<0.01) in pregnant women with SCH.A significant difference in the levothyroxine doses between SCH group 1 and SCH group 2 was found [(0.583 ± 0.341) vs (0.961 ± 0.405) μg/kg,t =-3.695,P< 0.01].The levothyroxine doses in SCH group 2 were 64.84% higher than those in group 1.There was a significant difference in the levothyroxine doses between thyroid autoantibody negative and positive subjects [(0.680 ± 0.370) vs (0.918 ±0.440) μg/kg,t =-2.197,P =0.032].The levothyroxine doses in thyroid autoantibody positive subjects were 35 % higher than those in the negative subjects.In addition,there was a significant difference in the levothyroxine doses between subjects with negative and positive thyroid autoantibody [(0.421 ± 0.192) vs (0.720 ± 0.385)μg/kg,t =-2.331,P =0.029] in SCH group 1.While in SCH group 2,the difference did not reach statistical significance.Conclusion The baseline TSH levels and status of thyroid autoantibodies may affect the levothyroxine dosage in pregnant women with SCH.

The purpose of this study is to explore depression metabolic markers in rat hippocampus and to investigate the anti-depressant effect of genipin and its mechanisms using nuclear magnetic resonance (NMR) metabonomics. Chronic unpredictable mild stress (CUMS) procedure was conducted to establish the depressive rat model. At the beginning of the third week, genipin low dose (25 mg x kg(-1)), middle dose (50 mg x kg(-1)), high dose (100 mg x kg(-1)), and venlafaxine (50 mg x kg(-1)) were given to the CUMS rats separately once daily for two weeks except control and model groups. Rat hippocampus was analyzed by 1H NMR based metabonomics after drug administration for 2 weeks. Significant differences in the metabolic profile of rat hippocampus of the CUMS treated group and the control group were observed with metabolic effects of CUMS including decreasing in glycine and N-acetylaspartate, increasing in inositol, glutamate, lactate, glutamine, taurine and alanine. Genipin showed ideal antidepressive effects at a dose of 50 mg x kg(-1) in rats, decrease of inositol, glutamate, lactate, alanine were observed, while glycine and N-acetylaspartate were increased. Important influence has been found on normal nervous system function of these significant changed metabolites, which suggests that the antidepressant effect of genipin may be played by enhancing the activity of neurons in hippocampus, repairing and improving the function of the neuron. The metabonomics approach is an effective tool for the investigation of the anti-depressant effect and pharmacologic mechanisms of genipin.

Subclinical hypothyroidism during pregnancy is associated with some adverse outcomes during maternal pregnancy.The present study investigated thyroid function parameters measured by electroehemiluminescence (ECL) immunoassays in subclinical hypothyroid women treated with levothyroxine (L-T4) during pregnancy.The results showed that in evaluating thyroid function with ECL immunoassays during replacement with L-T4,determination of serum TT4 appears to have a closer correlation with TSH and may better reflect the effìcacy of treatment.

Integrins are a family of cell surface glycoproteins that contribute to a variety of biological functions, including cell growth, migration, proliferation and morphology. In addition, integrins also play the important roles in pathological process. Several viruses have been showed to use integrins as receptors or co-receptors to infect host cells.This article mainly reviews the progress on integrins and their roles in FMDV infection.

Receptors are primary determinant of viral tropism and disease pathogenesis.Heparan sulfates (HS)are ubiquitous,polyanionic carbohydrate chains linked to core proteins in cell membranes and ex- tracellular matrices of all eukaryotes.HS have also been demonstrated to function as receptors or co-receptors for a number of different viruses.To date,HS and four RGD-dependent integrins,?v?3,?v?6, ?v?1,and?v?8 have been reported to serve as receptors for Foot-and-mouth disease virus(FMDV).Different receptors may be used to interact with host cells during FMDV infection.Studies on the structure and function of receptors are very important for understanding the interaction between host cells and FMDV. Here,We mainly reviews the progress on the biological characteristics of HS and its roles in FMDV infection.

Abstract: Objective To analyze the distribution and drug resistance evolution characteristics of pathogenic bacteria of bloodstream infection in nine tertiary hospitals in Yunnan Province from 2017 to 2021, so as to provide reliable basis for rational selection of antibiotics in clinic. Methods Using the drug sensitive paper method or instrument method, the bacteria identification and drug sensitivity test were carried out in nine tertiary hospitals in different regions according to the unified technical scheme. The results were judged according to the Clinical and Laboratory Standards Institute (CLSI) breakpoint standard in 2021, and use WHONET5.6 for data statistical analysis. Results A total of 12 003 strains of pathogenic bacteria were isolated from bloodstream infection samples in the past five years, including 7 442 strains of Gram-negative bacteria (62.0%) and 4562 strains of Gram-positive bacteria (38.0%), with an increasing trend in the number of isolated strains; of these, 163 strains (1.4%) were isolated from outpatients and 11 840 strains (98.6%) were isolated from inpatients. The top three gram-negative bacteria were Escherichia coli, Klebsiella pneumoniae and Acinetobacter baumannii, of which 309 strains (4.2%) were carbapenem-resistant Klebsiella pneumoniae (CR-KPN), 29 strains (0.4%) carbapenem-resistant Escherichia coli and 19 strains (0.3%) carbapenem-resistant Enterobacter cloacae, and the number of CR-KPN was on the rise year by year. The top three Gram-positive bacteria were coagulase-negative staphylococci, Staphylococcus aureus and Enterococcus faecium, of which methicillin-resistant Staphylococcus aureus (MRSA) was detected for 213 strains, accounting for 27.7%, and decreased from 40.0% in 2017 to 23.4% in 2021, showing a downward trend year by year. No vancomycin-resistant staphylococci and enterococci were found. Conclusions The detection and composition of bloodstream infection pathogenic bacteria in multicenter have not changed much in the past five years, but each hospital has its own characteristics. The number of carbapenem resistant Enterobacteriaceae increased year by year, which should be paid more attention.
