The normal reference ranges were calculated. The reference ranges of TSH, T3, T4, FT3, and FT4 were 1.09-4.60 mIU/L, 1.17-1.95 μg/L,57.43-99.60 μg/L, 5.35-7.50 pmol/L, 13.96-19.70 pmol/L, respectively. There was no significant difference in the interval of thyroid hormones between males and females as well as among different age groups.

Objective:To evaluate the quality condition and problems of acetylspiramycin at present. Methods:According to the standard described in Chinese Pharmacopoeia (2015 edition), acetylspiramycin and its preparations were determined, and the overall quality level of domestic acetylspiramycin was evaluated. The related substances, components and dissolution were analyzed to further explore the quality status. Results:In 258 batches of samples, the dissolution of only one batch did not meet the standard with the passing rate of 99. 6%. The results of exploratory research showed that the content of impurities in raw material was determined by the synthesis process, and the impurity profile of domestic and foreign formula was different. The dissolution behavior of domestic and for-eign formula in four kinds of media was not similar as well. Conclusion: The quality of domestic acetylspiramycin is promising. The research of related substances provides the reference for controlling the target impurities. The consistency assessment of dissolution pro-vides the reference for the formula process improvement and clinical application of acetylspiramycin tablets.

Objective To investigate the effects of recombinant bovine basic fibroblast growth factors combined with new rehabilitative liquid on neonatal diaper dermatitis. Methods One hundred and twenty neotates with neonatal diaper dermatitis from August 2013 to July 2014 were randomly divided into the control group and experiment group, 60 cases in each group. The control group was treated with conventional care, while the observation group with recombinant bovine basic fibroblast growth factors combined with new rehabilitative liquid. The total effective rate and the treatment time were compared between the two groups. Result The total effective rate of the observation group was significantly higher than that of the control group (P<0.05) and the treatment time of the observation group was statistically significantly shorter than that of the control group (P<0.05). Conclusion Recombinant bovine basic fibroblast growth factors combined with new rehabilitative liquid is effective in the treatment of neonatal diaper dermatitis and it is worth promoting and using clinically.

BACKGROUND: Hanshi Bi granule has been used to treat ankylosing spondylitis in the clinic, but the pharmacological mechanism B is still unclear. OBJECTIVE: To screen the compound and drug targets of Hanshi Bi granules based on network pharmacology, and construct a compound-target network to systematically investigate the pharmacological mechanism for treating ankylosing spondylitis. METHODS: The compounds and drug targets of Hanshi Bi granules were collected from TCMSP database. Ankylosing spondylitis targets were from DRUGBANK, GeneCards, Home-OMIM-NCBI, and PALM-IST databases. The obtained drug targets and disease targets were corrected by Uniprot database and common genes were obtained using Draw Venn Diagrams analysis tool. PPI analysis was performed on the common gene in combination with the STRING database and Cytoscape 3.6.1. GO enrichment analysis and KEGG pathway enrichment analysis were performed on the common gene by using Cytoscape 3.6.1 plugin ClueGO. RESULTS AND CONCLUSION: (1) Totally 69 active ingredients and 142 drug targets were obtained from TCMSP, and 595 ankylosing spondylitis targets were obtained using DRUGBANK, GeneCards, Home-OMIM-NCBI, and PALM-IST databases. (2) Using the Draw Venn Diagrams tool to analyze all targets, 39 common genes were obtained. Through PPI analysis, tumor necrosis factor, interieukin-6 and prostaglandin-in-peroxidase 2 were highly connected in the PPI network. (3) Through GO enrichment analysis, it mainly involved biological functions such as regulation of reactive oxygen metabolism, fatty acid metabolism, acute inflammatory reaction, neurotransmitter biosynthetic process, and metabolism of arachidonic acid. (4) Through KEGG pathway enrichment analysis, it mainly involved in AGE-RAGE signaling pathway, fluid shear stress and atherosclerosis, irtterieukin-17 signaling pathway, nuclear factor-KB signaling pathway, tumor necrosis factor signaling pathway, and Toll-like receptor signaling pathway. (5) This study preliminarily predicts the pharmacological mechanism underlying the treatment of ankylosing spondylitis with Hanshi Bi granules, and provides new ideas for secondary development of old drugs and experimental research.

The chelating reaction between glutathione peptides and divalent cadmium ion was used as a typical model for investigating the coordination chemistry of SH-containing peptides and heavy metal ions, which was essential to understand the mechanism of intracellular cadmium detoxification.Here, the mutant (CM113R)7 αHL protein nanopore equipped with a first synthesized per-6-quaternary ammonium-β-cyclodextrin (p-QABCD) was used as nanoreactor and detector to investigate the single-molecule reaction of GSH molecules and Cd2+ ions.Different reaction pathways, intermediates, and products could be recognized.Cd2+-GSH reaction was highly dependent on the solution pH.The Cd(GSH)2 was formed at pH 7.4, while the Cd(GSH)2 and Cd2(GSH)2 were formed at pH 9.0.Cd2(GSH)2 was formed by two possible pathways: (1) A Cd2+ ion primarily coordinated with the thiol group of two GSH molecules to form Cd(GSH)2, and then the second Cd2+ ion quickly incorporated with the deprotonated amino group of Cd(GSH)2 to form Cd2(GSH)2;(2) Two Cd2+ ions separately coordinated with the thiol and deprotonated amino group of one GSH molecule to form Cd2(GSH)1, and the second GSH molecule quickly bounded to Cd2+ ions to form Cd2(GSH)2.This work studied the chelating reaction between metal ions and bioactive glutathione at single-molecule level without labeling and chemical modification, and would be important to further understand intracellular mechanisms of detoxification of heavy metals and greatly expand the research field of nanopore single-molecule technique.
