The infectious clone plasmid of genotype Ⅰ Japanese encephalitis virus GX strain was suc-cessfully obtained by reverse transcription-polymerase chain reaction,where the cDNA of GX strain is divided into three fragments for amplification and the three fragments were sequentially cloned into pBR322 vector.After the infectious clone plasmid pGX was sequenced correctly,the pGX and pCAGGS-T7 eukaryotic plasmid were co-transfected into BHK-21 cells for virus rescue.The experimentalresults indicated that the Japanese encephalitis virus could be successfully res-cuedfrom BHK-21 cells.The plaque experiment and mouse experiment indicated that the rescued virus had similar replication ability and pathogenicity with wild type virus.It was confirmed that the infectious clone of genotype Ⅰ Japanese encephalitis virus GX strain was successfully construc-ted in this study.

Objective To survey the awareness and intended adoption of patient-based real-time quality control(PBRTQC)among medical laboratories,thereby providing a basis for subsequent research and promotion efforts.Methods An electronic questionnaire was distributed via the Questionnaire Star system to collect participants' general information,their knowledge,attitudes,and practices regarding PBRTQC,as well as their implementation willingness.Results A total of 161 valid questionnaires were collected.The sur-vey revealed that fewer than 50％of laboratory staff had basic knowledge of PBRTQC,and their confidence in establishing and applying PBRTQC in their own laboratories was low.However,they acknowledged its potential to enhance quality management.Key concerns and support needs for PBRTQC promotion include professional implementation guidelines and policy support,reliable third-party evalu-ations,software and hardware support,and user training.Conclusion The laboratory staff accepted the value of PBRTQC and gener-ally held a positive attitude toward its application.Future efforts should focus on developing standardized guidelines,refining evaluation methods,advancing software and hardware,and enhancing knowledge dissemination,technical training and other actions related to guiding the practical implementation thereby facilitating the wider adoption of PBRTQC.

Objective:To establish a reference interval for serum iodine of pregnant women with normal thyroid function and to analyze the relationship between serum iodine and thyroid disease risk.Methods:From July 2022 to October 2023, using cross-sectional survey method, pregnant women aged 18 to 48 years old who had lived in iodine-deficient areas in the six provinces of China (Shanxi Province, Fujian Province, Yunnan Province, Xinjiang Uygur Autonomous Region, Zhejiang Province, and Anhui Province) for more than six months were selected as the survey subjects. Blood samples were collected, serum iodine was tested, and the percentile method was used to establish a reference interval for serum iodine of pregnant women with normal thyroid function. Meanwhile, serum levels of free thyroxine, thyroid stimulating hormone, thyroglobulin antibody (TgAb), and thyroid peroxidase antibody (TPOAb) were tested, and logistic regression was used to analyze the relationship between serum iodine and thyroid disease risk.Results:A total of 1 409 pregnant women from 6 provinces were investigated, including 1 087 with normal thyroid function and 322 with abnormal thyroid function. The median serum iodine level of pregnant women with normal thyroid function was 79.74 μg/L, and the preliminary reference interval for serum iodine was 47.57 - 128.96 μg/L. When serum iodine levels were lower (< 47.57 μg/L), pregnant women had a significantly increased risk of developing TgAb positivity, TPOAb positivity, hypothyroxinemia, hypothyroidism, and autoimmune thyroiditis ( OR = 4.44, 2.91, 3.41, 41.67, 23.43, P < 0.05). When serum iodine levels were high (> 128.96 μg/L), pregnant women had a significantly increased risk of developing hyperthyroidism ( OR = 9.91, P = 0.001). Conclusions:The reference interval for serum iodine of pregnant women with normal thyroid function is successfully established. Low serum iodine levels are associated with an increased risk of TgAb positivity, TPOAb positivity, hypothyroxinemia, hypothyroidism, and autoimmune thyroiditis, while high serum iodine levels are associated with an increased risk of hyperthyroidism.

Objective:To discuss the effect of human umbilical cord mesenchymal stem cells culture supernatant(hUCMSCs-Sup)on the proliferation,apoptosis,and endometrium receptivity of the human endometrial stromal cells(hEndoSCs)treated with mifepristone(Ms),and to clarify the possible mechanism.Methods:The hEndoSCs were cultured in vitro and divided into control group and 40,60,80,and 100 μmol·L-1 Ms groups.The survival rates of the cells in various groups were detected by MTT assay.The hEndoSCs were divided into control group,40 μmol·L-1 Ms group,and 60 μmol·L-1 Ms group.The apoptotic rates of the cells in various groups were detected by flow cytometry;the expression levels of apoptosis-related protein B-cell lymphoma-2(Bcl-2)and Bcl-2-associated X protein(Bax)proteins in the cells in various groups were detected by Western blotting method,and the ratio of Bcl-2/Bax was calculated.After treated with hUCMSCs-Sup,the hEndoSCs were divided into control group,Ms group,Ms+hUCMSCs-Sup group,and Ms+hUCMSCs-Sup+3-methyladenine(3-MA)group.The survival rates of the cells in various groups were detected by MTT assay;the apoptotic rates of the cells in various groups were detected by flow cytometry;the expression levels of microtubule-associated protein 1 light chain 3B-Ⅱ(LC3B-Ⅱ)and microtubule-associated protein 1 light chain 3B-I(LC3B-Ⅰ)proteins in the cells in various groups were detected by Western blotting method,and the ratio of LC3B-Ⅱ/LC3B-Ⅰwas calculated;the expression levels of endometrium receptivity marker molecules mRNA in the cells in various groups were detected by real-time fluorescence quantitative PCR(RT-qPCR)method.Results:Compared with control group,the survival rates of the cells in 40,60,80,and 100 μmol·L-1 Ms groups were significantly decreased(P<0.05)in a time-dependent and dose-dependent manner.Compared with control group,the apoptotic rates of the cells in 40 and 60 μmol·L-1 Ms groups were significantly increased(P<0.05),and the ratios of Bcl-2/Bax were significantly decreased(P<0.05).After treated with hUCMSCs-Sup,compared with control group,the survival rate of the cells and ratio of LC3B-Ⅱ/LC3B-Ⅰ in the cells in Ms group were significantly decreased(P<0.05),the apoptotic rate was significantly increased(P<0.05),and the expression levels of homeobox A10(HOXA10),leukemia inhibitory factor(LIF),and integrin subunit beta 3(ITGB3)mRNA in the cells were significantly decreased(P<0.05);compared with Ms group,the survival rate of the cells and ratio of LC3B-Ⅱ/LC3B-Ⅰin the cells in Ms+hUCMSCs-Sup group were significantly increased(P<0.05),the apoptotic rate was significantly decreased(P<0.05),and the expression levels of HOXA10,LIF,and ITGB3 mRNA in the cells were significantly increased(P<0.05);compared with Ms+hUCMSCs-Sup group,the survival rate of the cells and ratio of LC3B-Ⅱ/LC3B-Ⅰ in the cells in Ms+hUCMSCs-Sup+3-MA group were significantly decreased(P<0.05).Conclusion:hUCMSCs-Sup can increase the survival rate and decrease the apoptotic rate of the hEndoSCs after treated with Ms,and increase the endometrium receptivity,and its mechanism may be associated with the activation of autophagy of the hEndoSCs by hUCMSCs-Sup.

OBJECTIVE To sort out the chemical drugs for children in China's over-the-counter(OTC) drugs catalogue and analyze the drug categories and the specification of the instructions, so as to find out the key points that lead to the risk of drug use, and put forward suggestions for improvement. METHODS According to the sample of OTC drugs instructions published on the website of the National Medical Products Administration, as well as the results of clinical expert investigation and literature, the OTC drugs catalog of children's chemical drugs was determined and classified, and the investigate the standardization and consistency of the instructions. RESULTS There were 267 kinds of OTC drugs for children sorted out, involving 18 kinds of diseases. A considerable proportion of the instructions were incomplete and nonstandard, and there were few kinds of drugs for respiratory and digestive diseases. CONCLUSION The preparation and publicity of children OTC drugs instructions should be standard, the research and development of children's OTC drugs should be strengthened, the training of pharmacy employees should be strengthened, and ensure the rational and safe use of children's OTC drugs.
