OBJECTIVE To explore the effects of dexmedetomidine （DEX） increasing serpin peptidase inhibitor clade E member 1 （SERPINE1） protein on the malignant biological behavior of thyroid carcinoma （THCA） cells. METHODS THCA cells （KTC-1， TPC-1） were treated with 1， 10 and 100 nmol/L DEX， and their viabilities， clone formation rates， migration rates and invasion number were examined. Potential biological functions of DEX in THCA cells were analyzed through whole genome sequencing and gene ontology enrichment analysis. The core targets of DEX were mined through a protein-protein interaction network. The expression characteristics of DEX core targets and their relationship with patient prognosis were evaluated. The effects of DEX on mRNA and protein expressions of core targets and protein secretion in 2 types of THCA cells were detected， and the effects of this target on DEX-related effects were validated preliminarily by knocking down the core target. RESULTS Compared with the control group （0 nmol/L DEX）， DEX at 1， 10 and 100 nmol/L significantly increased the viabilities of 2 types of THCA cells （except for the KTC-1 cells in the 1 nmol/L DEX group at 24 h）， concentration-dependently elevated the rates of clone formation， migration rates （except for 2 types of THCA cells in 1 nmol/L DEX group）， and the number of invasion （P＜0.05）. A total of 287 differently expressed genes （75 up- tongxueyan180@163.com regulated and 212 down-regulated） were enriched in signaling pathways such as phosphatidylinositol 3-kinase/protein kinase B， Wnt， and senescence-associated secretory phenotypes in the 2 kinds of DEX-treated or non-treated THCA cells. SERPINE1 was a core target of DEX for THCA， and its mRNA and protein expression in THCA tissues/cells were significantly elevated and associated with poor prognosis of the patients （P＜0.05）. Compared with the control group， mRNA and protein expression of SERPINE1 was significantly up-regulated in 2 types of cells in the 1， 10 and 100 nmol/L DEX groups， while the secretion of this protein in conditioned medium was also significantly increased， all of which showed concentration-dependence （P＜0.05）. After knocking down SERPINE1， the promoting effects of DEX on the proliferation， colony formation， migration and invasion abilities of two types of THCA cells were significantly inhibited （P＜0.05）. CONCLUSIONS DEX can promote the proliferation， migration and invasion of THCA cell， and the above effects may be associated with the expression of increased secretory SERPINE1 protein.

Objective To identify factors associated with gastrointestinal heat retention in preschool children,and to provide a foundational understanding for future clinical investigations. Methods A case-control study was performed,which involved children from kindergartens in the Longgang District of Shenzhen City,Guangdong Province,from May to July 2021. Using the Children's Gastrointestinal Heat Retention Diagnostic Self-assessment Scale,subjects were allocated into a case group (children diagnosed with gastrointestinal heat retention) and a control group (children without this condition). An online survey was used to collect data on dietary behaviors,caregivers' feeding behaviors,early antibiotic use,daily routines,and birth conditions. SPSS 27.0 software was used to facilitate precise sociodemographic matching and paired logistic regression analysis to explore the association between gastrointestinal heat retention and the above factors. Results From the analysis of 51,252 matched cases,the study found that several factors contributed to an increased risk of gastrointestinal heat retention. These factors included reduced food intake compared to peers,reports of picky eating by caregivers,distractions during meals,pronounced dietary preferences,disinterest in food,meal durations ≥ 25 min,reluctance to sample new foods,consistent refusal of specific food types for over one month,irregular meal locations,coercive feeding practices,use of micronutrient supplements,allowing children too much freedom in food choice,persuading children to eat,infrequent encouragement to experiment with new foods,early antibiotic introduction,inadequate sleep,and premature birth (P<0.05). In contrast,exclusive breastfeeding in the first six months,engagement in moderate to massive physical activity,and regular napping patterns were associated with a reduced risk of gastrointestinal heat retention (P<0.05). Conclusion The suboptimal dietary habits,improper feeding practices,insufficient physical activity,inadequate sleep,and premature antibiotic exposure may be significant risk factors for gastrointestinal heat retention. Future research dedicated to unraveling the cause of gastrointestinal heat retention should prioritize these elements.

Objective:To analyze the prenatal diagnosis results and pregnancy outcomes of fetal growth re-striction(FGR)with varying severity and provide guidance for clinical counseling and management of FGR.Meth-ods:A total of 141 pregnant women with FGR treated at Sichuan Maternal and Child Health Hospital from January 2020 to June 2021 were selected for the retrospective study.They were divided into the mild FGR group(3th≤EFW＜10th,84 cases)and the severe FGR group(EFW＜3th,57 cases)based on different estimated fetal weight(EFW).All pregnant women underwent amniocentesis for prenatal diagnosis.The chromosome results and preg-nancy outcomes of the two groups were statistically analyzed.Results:19 cases(13.5%)of 141 fetuses with FGR were found with chromosome abnormalities.The rate of chromosomal abnormalities was 19.3%(11/57)in the severe FGR group,which was higher than the 9.5%(8/84)in the mild FGR group,but the difference was not statistically significant(P=0.095).110 cases underwent both karyotype analysis and chromosome microarray a-nalysis(CMA).The detection rate of chromosomal abnormalities in CMA was 13.6%,which was significantly higher than 4.5%in karyotype analysis(P=0.006).Among chromosomal abnormalities,chromosomal aneu-ploidy accounted for 21.05%(4/19),including 1 case of trisomy 18 and 2 cases of 47,XXY.Two cases with dele-tion in the 4p16.3 regions were found in the severe FGR group,and these deletions are associated with Wolf-Hir-schhorn syndrome.The termination rate of pregnancy and admission to the neonatal intensive care unit in the se-vere FGR group were higher than those in the mild FGR group.In contrast,the full-term delivery rate and newborn birth weight were lower in the severe FGR group compared to the mild FGR group,showing statistically significant differences(P＜0.05).There was no statistically significant difference in the rates of stillbirth and preterm birth be-tween the two groups(P＞0.05).Conclusions:The detection rate of chromosomal abnormalities using CMA in fetuses with FGR was higher than traditional karyotyping.Therefore,it is recommended to combine karyotyping with CMA for invasive prenatal diagnosis of FGR fetuses.The risk of adverse pregnancy outcomes increases with severe FGR,and monitoring should be intensified during pregnancy and the perinatal period to reduce adverse pregnancy outcomes.

Signal transducer and activator of transcription 3(STAT3)is an intracellular signaling factor that plays a critical role in various cellular processes,including the growth,differentiation,apoptosis,and immune response of cells.Aberrant activation of T helper cell 17(Th17)is closely associated with the morbidity and progress of various autoimmune diseases.STAT3 participates in the pathogenesis of Sj?gren syndrome by inducing excessive proliferation and abnormal differentiation of Th17 cells and affecting lymphocyte infiltration into exocrine glands.Therefore,targeting the STAT3 signaling pathway represents a potential novel therapeutic approach for the treatment of Sj?gren syndrome.This review summarizes the research of STAT3 in the pathogenesis and progression of Sj?gren syndrome through regulating Th17 cells,focusing on current inhibitors targeting the STAT3 signaling pathway as potential therapeutic targets for Sj?gren syndrome.

Background::Risk assessment and treatment stratification for three-vessel coronary disease (TVD) remain challenging. This study aimed to investigate the prognostic value of left atrial volume index (LAVI) with the Synergy Between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery (SYNTAX) score II, and its association with the long-term prognosis after three strategies (percutaneous coronary intervention [PCI], coronary artery bypass grafting [CABG], and medical therapy [MT]) in patients with TVD.Methods::This study was a post hoc analysis of a large, prospective cohort of patients with TVD in China, that aimed to determine the long-term outcomes after PCI, CABG, or optimal MT alone. A total of 8943 patients with TVD were consecutively enrolled between 2004 and 2011 at Fuwai Hospital. A total of 7818 patients with available baseline LAVI data were included in the study. Baseline, procedural, and follow-up data were collected. The primary endpoint was major adverse cardiac and cerebrovascular events (MACCE), which was a composite of all-cause death, myocardial infarction (MI), and stroke. Secondary endpoints included all-cause death, cardiac death, MI, revascularization, and stroke. Long-term outcomes were evaluated among LAVI quartile groups. Results::During a median follow-up of 6.6 years, a higher LAVI was strongly associated with increased risk of MACCE (Q3: hazard ratio [HR] 1.20, 95% confidence interval [CI] 1.06-1.37, P = 0.005; Q4: HR 1.85, 95%CI 1.64-2.09, P <0.001), all-cause death (Q3: HR 1.41, 95% CI 1.17-1.69, P <0.001; Q4: HR 2.54, 95%CI 2.16-3.00, P <0.001), and cardiac death (Q3: HR 1.81, 95% CI 1.39-2.37, P <0.001; Q4: HR 3.47, 95%CI 2.71-4.43, P <0.001). Moreover, LAVI significantly improved discrimination and reclassification of the SYNTAX score II. Notably, there was a significant interaction between LAVI quartiles and treatment strategies for MACCE. CABG was associated with lower risk of MACCE than MT alone, regardless of LAVI quartiles. Among patients in the fourth quartile, PCI was associated with significantly increased risk of cardiac death compared with CABG (HR: 5.25, 95% CI: 1.97-14.03, P = 0.001). Conclusions::LAVI is a potential index for risk stratification and therapeutic decision-making in patients with three-vessel coronary disease. CABG is associated with improved long-term outcomes compared with MT alone, regardless of LAVI quartiles. When LAVI is severely elevated, PCI is associated with higher risk of cardiac death than CABG.
