ObjectiveTo investigate the influence of empagliflozin combined with donafenib or lenvatinib on the pharmacokinetic parameters of each drug， and to provide a reference for combined medication in clinical practice. MethodsA total of 48 healthy male Sprague-Dawley rats were divided into 8 groups： empagliflozin group 1 and 2， donafenib group， lenvatinib group， donafenib pretreatment+empagliflozin group， lenvatinib pretreatment + empagliflozin group， empagliflozin pretreatment+donafenib group， and empagliflozin pretreatment+lenvatinib group， with 6 rats in each group. The doses of empagliflozin， donafenib， and lenvatinib were 2.5 mg/kg， 40 mg/kg， and 1.2 mg/kg， respectively. The rats in the empagliflozin group， donafenib group， and lenvatinib group were given a blank solvent by gavage for 7 consecutive days， followed by a single dose of empagliflozin， donafenib， or lenvatinib on day 7 after the administration of the blank solvent； the rats in the pretreatment groups were given the pretreatment drug by gavage for 7 consecutive days， followed by a single dose of drug combination on day 7 after administration of the pretreatment drug. Blood samples were collected at different time points， and plasma was separated to measure the concentration of each drug. A validated ultra-performance liquid chromatography-tandem mass spectrometry method was used to measure the plasma concentrations of donafenib， lenvatinib， and empagliflozin， and a non-compartmental model was used to calculate the main pharmacokinetic parameters of each drug （area under the plasma concentration-time curve ［AUC］， time to peak ［T_max］， peak concentration ［C_max］， and half-life time ［t_1/2］）. The independent-samples t test was used for comparison of normally distributed continuous data between two groups， and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups. ResultsCompared with the empagliflozin group， the donafenib pretreatment+empagliflozin group had significant increases in the AUC_0-t and AUC_0-∞ of empagliflozin （P=0.011 and 0.008）， while the lenvatinib pretreatment+empagliflozin group had no significant change in the AUC of empagliflozin， with a slightly shorter T_max （P=0.019）. Compared with the donafenib group， the empagliflozin pretreatment+donafenib group had significant increases in the AUC_0-t and AUC_0-∞ of donafenib （P=0.027 and 0.025）， as well as a significant increase in C_max （P=0.015） and significant reductions in CLz/F and Vz/F （P=0.005 and 0.004）； compared with the lenvatinib group， the empagliflozin pretreatment+lenvatinib group had a reduction in the t_1/2 of lenvatinib by approximately 5 hours （P=0.002）， with a trend of reduction in AUC_0-t （P0.05）. ConclusionEmpagliflozin combined with donafenib may alter the pharmacokinetic parameters of both drugs， leading to a significant increase in the exposure levels of both drugs， and efficacy and adverse reactions should be monitored during co-administration. There are no significant changes in the exposure levels of empagliflozin and lenvatinib during co-administration.

Professor LIU Qingguo's academic thoughts and clinical experience in treating pediatric tic disorders with scalp fire needling is introduced. Professor LIU believes that the core pathogenesis of this disease lies in "wind stirring and qi disorder, leading to the spirit failing to govern the body". Therefore, treatment should focus on "regulating the spirit to stabilize the form and extinguishing wind to stop movement". Clinically, the main acupoints include Shenting (GV24), Benshen (GB13), Xinhui (GV22), Baihui (GV20), Sishencong (EX-HN1), Fengchi (GB20), and Fengfu (GV16), which are rapidly punctured with fine fire needles, leading to significant therapeutic efficacy.

Objective To comprehensively assess the strengths and weaknesses of the 24 antihypertensive drugs procured as Volume-based Procurement(VBP)and innovator drugs by using quantitative evaluation system,and to provide a reference for doctors and patients in medication guidance and pharmaceutical decision-making.Methods The Quantitative Evaluation Criteria in the"Quick Guide to Drug Evaluation and Selection in Chinese Medical Institutions"were refined and optimized.The 24 selected VBP and innovator antihypertensive drugs were quantitatively evaluated according to the optimized quantitative evaluation system with the help of Chinese and English databases such as China Knowledge Network,Wanfang data,Wipunet,Embased,PubMed,and Metstr,as well as guideline search tools such as Meikang MCDEX,Drugwise Data,Up To Date,Medical Pulse and other databases etc.Results Among the 24 antihypertensive drugs,only four innovator drug evaluation scores were higher than those of drugs selected as VBP,namely felodipine tablets,Fosinopril sodium tablets,indapamide extended-release capsules,Irbesartan hydrochlorothiazide tablets.there were five main differences in the evaluation scores,namely economy,consistency evaluation,drug expiry date,global use,and the status of manufacturing enterprises.It was found that 83%of the VBP drugs had higher evaluation scores than those of the innovator drugs.The economic score of the innovator drug was low,and the difference in the scores was between 1-11 points.Conclusion By using the quantitative evaluation system to evaluate the antihypertensive drugs,the advantages and disadvantages of the innovator and VBP antihypertensive drugs can be assessed comprehensively,and the digital characteristics of antihypertensive drugs can be given,and the evaluation score can provide the reference basis for the guidance and decision-making of medication for doctors and patients.

Objective:To explore the risk factors of borderline subclinical hypothyroidism during first trimester of pregnancy in euthyroid patients with recurrent spontaneous abortion history.Methods:Among the 3 794 outpatients in the Sixth Obstetric Clinic of Shengjing Hospital of China Medical University from July 2017 to July 2019, 302 patients with recurrent spontaneous abortion and euthyroid function before pregnancy were selected after excluding those with abnormality in anatomy, coagulation, genetics, endocrine, infection, and immunology aspects through a systematic etiological screen. Exclusion of 62 patients with pre-pregnancy thyroid stimulating hormone (TSH) above 2.5 mIU/L, 240 recurrent spontaneous abortion patients were finally included. Borderline subclinical hypothyroidism is defined as the level of TSH higher than 2.5 mIU/L but less than the upper limit of pregnancy specific reference range during the first trimester. Among these 240 recurrent spontaneous abortion patients, 84 had borderline subclinical hypothyroidism and 156 were not. After analyzing the history, clinical and laboratory examination results of the two groups of patients, univariate analysis and multivariate logistic regression analysis were applied, to analyze and screen the high-risk factors of borderline subclinical hypothyroidism. Collinear diagnosis of regression analysis and correlation analysis were used to find out the if further relationships among the high-risk factors existed.Results:Univariate analysis suggested that conception method, pre-pregnancy TSH level, anti-nuclear antibody (ANA), lupus anticoagulant (LAC), and anti-β2 glycoprotein 1 (β2GP1) antibody were the potential high-risk factors ( P<0.1). Multivariate logistic regression analysis showed that pre-pregnancy TSH level>1.5 mIU/L ( OR=5.241, 95% CI 2.659-10.330), ANA positive ( OR=3.614, 95% CI 1.866-7.000), anti-β2GP1 antibody positive ( OR=3.415, 95% CI 1.176-9.917), and LAC positive ( OR=2.785, 95% CI 1.024-7.573) were independent risk factors of borderline subclinical hypothyroidism ( P<0.05 or P<0.01). No significant collinearity was found among the factors in the collinearity diagnosis. Except for the thyroid peroxidase antibody and thyroglobulin antibody ( P<0.01), no significant correlation was found among the non-organ-specific antibodies (NOSAs) and antithyroid antibodies. Conclusion:The level of pre-pregnancy TSH and NOSAs before pregnancy are the most important risk factors of borderline subclinical hypothyroidism during first trimester of pregnancy of euthyroid patients with recurrent spontaneous abortion history.

OBJECTIVE： To standardize the management of temporary drug purchase， and to provide reference for drug selection in Hospital Pharmaceutical Administration and Drug Treatment Committee （Pharmaceutical Association）. METHODS： Clinical pharmacists set up drug quantitative scoring table according to the 10 attributes of drugs as effectiveness， safety， economy， etc. 15 temporary purchased drugs submitted by departments in Oct. 2018 were graded according to the rules of the scoring table， and the evaluation results were fed back to Pharmaceutical Association. A retrospective evaluation of 20 temporary purchased drugs which were discussed at the Pharmaceutical Association from Jul. to Sept. 2018 was made according to previous approval model without using drug quantitative scoring table. The effect of pre-intervention was evaluated after using drug quantitative scoring table. RESULTS： Among 15 temporary purchased drugs， 2 of them scored below 60， and the unqualified rate was 13.3％. It suggested that 2 drugs could not be discussed at the meeting. Among 20 temporary purchased drugs that have been discussed at the meeting， 9 of them scored below 60， with the unqualified rate of 45.0％， suggesting that 9 drugs may have wasted the workload of the Pharmaceutical Association. CONCLUSIONS： Drug quantitative scoring table can play a pre-intervention role in the scoring of temporary purchased drugs to a certain extent. At the same time， the table can also be used as a relevant reference for hospital drug evaluation. It is helpful to optimize hospital drug use list and improve the level of rational drug use in clinic.
