Purpose To investigate the expression of thioredoxin-interacting protein(TXNIP)in placental tissues of gestational diabetes mellitus(GDM)and its role in lipid deposition in the placental trophoblast.Methods The pla-centa tissues of 16 GDM pregnant women and 25 women with normal glucose tolerance(NGT)were collected.Mean-while,in vitro models of high-glucose induced human chorionic trophoblast cells(HTR-8/SVneo)were established,which were divided into normal glucose control group(NG),high glucose group(HG),high glucose+si nonsense in-terference group(HG+siNC)and high glucose+TXNIP siRNA group(HG+siTXNIP).The pathological structure and morphological changes of placenta were observed by HE staining.Lipid droplet formation was detected by oil red O staining.The expression and localization of TXNIP in cells were detected by immunocytochemical EnVision method.The mRNA and protein expression levels of TXNIP and lipogenic protein SREBP1 were detected by real-time fluorescent quantitative PCR and Western blot.The relationships between TXNIP expression and lipid droplet accumulation in-duced by high glucose was analyzed.Results High glucose results in abnormal placental structure of GDM.The area of human chorionic intervillous tissue in placenta of GDM group was decreased,the size of fetal capillaries was different and the lumen was dilated.Compared with those NGT group,the accumulation of lipid droplets and the expression of TXNIP mRNA and protein in placental tissue of GDM were increased(P＜0.05).The TXNIP and SREBP1 were up-regulated and the formation of droplets increased in high glucose induced HTR-8/SVneo cells(P＜0.05).On the con-trary,TXNIP siRNA transfection reversed the gene expression level and lipid deposition in high glucose induced cells(P＜0.05).Conclusion TXNIP is involved in abnormal lipid deposition in the placental trophoblast of GDM.

Purpose To compare the HRCT findings of lung damage in patients with idiopathic inflammatory myopathies(IIMs)with positive and negative anti-Ro-52 antibody.Materials and Methods Fifty patients with IIMs admitted to Beijing Shijitan Hospital,Capital Medical University from January 2015 to July 2023 were retrospectively analyzed.The patients were divided into anti-Ro-52 antibody negative group(18 cases)and positive group(32 cases),the lung CT findings of the two groups were compared,the distribution of lung lesions and related signs were analyzed.Results The incidence of interstitial lung disease in the anti-Ro-52 antibody-negative group was 11.1%(1 case),which was lower than that in the positive group 75.6%(31 cases)(P=0.001).Among the interstitial lung disease-positive patients,the proportion of lesions in the anti-Ro-52 positive group was more symmetrical(28 cases,87.5%,P=0.022)and peripheral distribution(20 cases,62.5%,P=0.039)than that in the anti-Ro-52 negative group.Non-specific interstitial pneumonia-like lesions were the main lesions in the two groups,including 14 cases(43.8%)in the anti-Ro-52 positive group and 7 cases(38.9%)in the negative group.However,9 cases(28.1%)of the anti-Ro-52 positive group had acute interstitial pneumonia-like lesions and 1 case(5.6%)of the negative group had acute interstitial pneumonia-like lesions.Imaging accompanying signs:anti-Ro-52 positive combination and consolidation(14 cases,43.8%,P=0.009),nodular shadow(17 cases,53.1%,P=0.025),and reverse halo sign(12 cases,37.5%,P=0.021)were more than those in the anti-Ro-52 negative group.Conclusion IIMs patients with positive anti-Ro-52 antibody have a higher incidence of interstitial lung disease.HRCT findings are of great significance for diagnosis and treatment of IIMs.

The success of"New Medical Sciences"in higher education requires effective tools in evalua-ting students'performance in courses.Previously,we reported a teamwork(T),critique(C)and ap-preciation(A)(TCA)ideological and political model,a teaching model widely applied in Basic Medical courses.TCA is an abbreviation derived from Tricarboxylic Acid Cycle in Biochemistry as an analogy for nurturing the abilities of thinking and teamwork(T),critique(C)and appreciation(A),which hope-fully could provide students with moral norms for cognition,science and life.This paper further explores the tools to assess the educational outcomes of the TCA model,by which teachers can collect feedback and reflect on teaching quality and effectiveness.Addressing the challenges of individual differences in large classes,fragmented learning feedback,and the difficulty of measuring meta-cognition in educational evaluation,this study employs strategies of value-added assessment,matrix assessment and norm-transfer-able assessment to evaluate the TCA abilities from the aspects of thinking quality,thinking creativity,co-operation ability,iterative thinking,dialectical thinking and job responsibility.By modifying/using 18 e-valuation tools in Education and Psychology,we have established a rubric system composed of 30 primary indicators(with 11 newly designed,10 partly modified and 9 directly adopted),along with 49 secondary indicators and 98 tertiary indicators to enhance the feasibility of the evaluation process.This rubric sys-tem was applied to Biochemistry teaching among the five-year-program undergraduates at Air Force Medi-cal University.Specifically,thinking and teamwork are evaluated by creative works from"the magic bio-chemical-circle",while critiques are assessed in large classes under the guidance of basic and clinical teachers,coupled with appreciation measured by job responsibility in a task-driven virtual reality(VR)project.The results indicate that Biochemistry teaching not only accumulates knowledge in students,but also achieves the goals in nurturing values and cognition.The inclusion of creative performance evalua-tion,cooperative learning and clinical case studies,can enhance students'interpersonal skills,coopera-tion,quality of thinking,creative thinking,iterative thinking and dialectical thinking to varying degrees.TCA-based Biochemistry teaching has a long-lasting impact on character education,and is capable of in-ducing positive long-term changes in students'cognition and lifestyle.Taken together,with the help of this rubric system,teachers can promptly acknowledge the effectiveness of their teaching,thereby facilita-ting their teaching strategies.

Objective To investigate the effect of Nde1 gene knockout on early neural development of zebrafish by visualizing the development of neural networks in zebrafish.Methods Transgenic zebrafish Tg(Nde1-/-;HuC:RFP+/-)was constructed by crossing Nde1-/-with Tg(HuC:RFP+/-).The HuC promoter was employed to drive the expression of red fluorescent protein in neurons,which allowing the visualization of zebrafish neural networks and tracking of neural development.Furthermore,by using Image J and Prism to compare the average fluorescence intensity of neurons and the expression level of fluorescent reporter proteins between Nde1 deficiency zebrafish and wild type zebrafish,the effect of Nde1 gene knockout on zebrafish neural development was analyzed.Results From 48 hours post-fertilization(hpf)to 7 days dpf,the average fluorescence intensity of red fluorescence expressed by trigeminal sensory neurons and spinal cord neurons in Nde1 deficiency zebrafish was lower than that in wild type zebrafish.RT-qPCR results also showed that the mRNA expression level of red fluorescent reporter protein in Nde1 deficiency zebrafish was significantly lower than that in the wild type zebrafish.Conclusion Nde1 gene deletion may lead to abnormal development of trigeminal sensory neurons and spinal cordneurons by affecting neural progenitor cell differentiation and increasing apoptosis.

Objective:To explore the correlation between anxiety, depression, and inflammatory markers in the body fluids of patients with burning mouth syndrome (BMS), creating a preliminary assessment model based on clinical data.Methods:Forty-one BMS patients were recruited according to the predefined inclusion criteria and exclusion criteria from the Department of Oral Medicine, Shanghai Ninth People′s Hospital, Shanghai Jiao Tong University School of Medicine between December 2021 and September 2023, along with 12 healthy controls. The pain intensity of the 41 patients was assessed using the visual analog scale (VAS). Meanwhile, anxiety and depression were assessed using the Zung self-rating anxiety scale (SAS) and the Zung self-rating depression scale (SDS). The concentrations of brain-derived neurotrophic factor (BDNF), interferon-γ (IFN-γ), interleukin (IL)-1β, IL-6, IL-8, and tumor necrosis factor-alpha (TNF-α) in saliva and serum were measured using the Luminex 200 TM system and enzyme-linked immunosorbent assay. Statistical analyses were performed using the Chi-square test, independent samples t-test, ANOVA, Spearman′s correlation analysis, and multiple linear regression, respectively. Results:The VAS score for the 41 BMS patients was (3.56±1.90), with 48.8% (20/41) and 41.5% (17/41) of patients experiencing mild and moderate pain, respectively. Only 7.3% (3/41) of patients had severe pain. Among the 41 BMS patients, 61.0% (25/41) exhibited anxiety and/or depression, in whom 39.0% (16/41) had both anxiety and depression, 9.8% (4/41) experienced anxiety without depression, and 12.2% (5/41) had depression without anxiety. The concentrations of IFN-γ and TNF-α in the serum and saliva of BMS patients were significantly higher than those in healthy controls (all P<0.05). In contrast, the BDNF concentration in serum was significantly lower in BMS patients than in healthy participants ( P<0.01), but was significantly higher in saliva ( P<0.001). Serum TNF-α was positively correlated with IFN-γ, IL-1β, and IL-6 (β=0.803, β=0.812, β=0.592; all P<0.01), while saliva TNF-α was negatively correlated with both anxiety and depression (β=-0.325, β=-0.321; all P<0.05). SAS scores were linearly correlated with saliva TNF-α concentrations (SAS=51.374-1.154×saliva TNF-α); saliva TNF-α concentrations were linearly correlated with saliva IFN-γ and IL-1β (saliva TNF-α=2.408+0.281×saliva IFN-γ+0.002×saliva IL-1β). Conclusions:This study provides a preliminary exploration of a clinical assessment model for BMS based on inflammatory markers and psychological scores, offering an exploratory framework for further research and optimization of the model.

Objective:To explore the intervention effects of the skill training for parents with autism child (STPAC) on toddlers with autism spectrum disorder (ASD).Methods:A multicenter non-randomized concurrent controlled study design was conducted. Thirty children with ASD aged 15-30 months, first diagnosed at the Children′s Hospital of Fudan University, the First Hospital of Jilin University, and Chengdu Women′s and Children′s Central Hospital from 2019 to 2020, were enrolled in the STPAC group. Thirty children with ASD who visited the same hospitals during the same period but refused the STPAC intervention were selected as the control group. The STPAC group received an 8-week intervention (3 h/week) followed by quarterly follow-ups for 1 year, while the control group voluntarily chose community-based routine interventions. The Griffiths development scales-Chinese (GDS-C) was used to assess the developmental levels, and the communication and symbolic behavior scales developmental profile infant-toddler checklist (CSBS-DP-ITC) was completed by the primary caregivers to evaluate social, language and symbolic behavior. The independent samples t-tests or Mann-Whitney U tests, etc.was used for inter-group comparison. The paired t-tests or Wilcoxon signed-rank tests, etc. was used for inter-group pre-post intervention comparison. Results:The STPAC group included 30 children (22 males and 8 females, aged (23.9±2.2) months), and the control group included 30 children (20 males and 10 females, aged (24.2±2.6) months). Before the intervention, there were no statistically differences in GDS-C development quotient (DQ) and CSBS-DP-ITC scores between groups (all P>0.05). After 1-year intervention, GDS-C DQ in personal-social, hearing-language, hand-eye coordination, performance domains of STPAC group and GDS-C DQ in personal-social, hearing-language domains of control group were all increased (all P<0.01). After 1-year intervention, CSBS-DP-ITC scores of both groups were all improved in socia, language, symbolic behavior, and total scores (all P<0.001). GDS-C DQ changes before and after 1 year of intervention in hearing-language, hand-eye coordination, performance domains of the STPAC group were all higher the those of control group (34(15, 48 vs. 10(-4, 39), 11±20 vs. -1±19, 23±25 vs. 8±22, all P<0.05). CSBS-DP-ITC scores changes before and after 1 year of intervention in social and total scores of the STPAC group were both higher the those of control group (10(5, 30) vs. 3(1, 7), 26±17 vs. 11±8, both P<0.001). Conclusion:Compared with the community routine interventions, the STPAC better improves the language, hand-eye coordination, visual-spatial, social communication, and play skills in ASD toddlers.

Objective:To explore the effect of Shenxianling granules on the pharmacokinetics of ondansetron. Methods:A method for detecting the plasma concentration of ondansetron using highperformance liquid chromatography (HPLC) was established. The reliability of the method was validated through specificity, linear relationship, precision, stability, repeated experiments, and sample recovery rate testing. Thirty six healthy male New Zealand rabbits were randomly divided into 2 groups, with 18 rabbits in each group. Rabbits in the single ondansetron group (single drug group) received intravenous injection of ondansetron 0.92 mg/kg through the ear vein. Rabbits in the Shenxianling granules combined with ondansetron group (combination drug group) were firstly given 575 mg/kg of Shenxianling granules by gavage continuously for 10 days, and on the morning of the 11th day, ondansetron 0.92 mg/kg was intravenously injected. Blood samples were collected before administration and at 5 minutes, 10 minutes, 20 minutes, 30 minutes, 45 minutes, 1 hour, 2 hours, 4 hours, 5 hours, 6 hours, 7 hours, 8 hours, 10 hours and 24 hours after administration of ondansetron. The blood concentration of ondansetron was detected using HPLC method and pharmacokinetic parameters were calculate. Results:Two New Zealand rabbits in the combination drug group developed agitation and cough, and then died on the second and fifth day of gavage, respectively. Therefore a total of 18 and 16 rabbits in the single drug group and the combination drug group completed the experiment, respectively. After ondansetron administration, the plasma concentration of ondansetron increased rapidly in the single drug group and remained at low levels in the combination drug group. From 5 minutes to 10 hours after administration, the plasma concentration of ondansetron at the 13 blood sampling time points in the combination drug group was significantly lower than that in the single drug group, and the differences were statistically significant (all P<0.001). Compared with the single drug group, the plasma clearance half-life of ondansetron in the combination drug group was significantly prolonged, the peak time, peak concentration, concentration at the last time and area under the curve (AUC) were all significantly reduced, and the percen- tage of residual or extrapolated area to the overall AUC, apparent volume of distribution, and clearance/bioavailability ratio were significantly increased; the differences were statistically significant (all P<0.001). Conclusions:There is a significant interaction between Shenxianling granules and ondansetron, leading to a decreased plasma concentration of ondansetron. The mechanism may be related to Shenxianling granules altering the tissue distribution of ondansetron within the body.
