ObjectiveTo observe the clinical effectiveness and potential mechanism of combined tongue three-needle acupuncture and acupoint application on Lianquan （CV 23） for patients with dysphagia after ischemic stroke. MethodsA prospective study was conducted on 160 patients with post-stroke dysphagia， who were randomly divided into a treatment group and a control group， with 80 cases in each group. The control group received conventional rehabilitation training， while the treatment group received tongue three-needle acupuncture combined with acupoint application on Lianquan （CV 23） on the basis of conventional rehabilitation training， for 4 weeks in both groups. We compared the clinical effectivenss of both groups after treatment， and assessed the swallowing function including videofluoroscopic swallowing study （VFSS）， standardized swallowing assessment （SSA） and functional oral intake scale （FIOS）， swallowing contrast test including hyoid maximum displacement （HmaxD）， pharyngeal transit time （PTT）， and upper esophageal sphincter （UES） opening， surface electromyography （sEMG） test including maximum amplitude and swallowing duration as well as swallowing quality of life questionnaire （SWAL-QOL） score of the patients in both groups before treatment， after 2 weeks and 4 weeks of treatment， respectively. ResultsThe total effective rate in treatment group was 82.50% （66/80）， significantly higher than 66.25% （53/80） in control group （P＜0.05）. The VFSS， and FOIS scores， UES opening rate and HmaxD， sEMG maximal amplitude values， and SWAL-QOL scores were increased in both groups after 2 weeks and 4 weeks of treatment compared with the values before treatment （P＜0.05）， while SSA scores， PTT， and swallowing duration were decreased compared within group before treatment （P＜0.05）. VFSS and FOIS scores， UES opening rate and HmaxD， sEMG maximal amplitude values， and SWAL-QOL scores after 2 and 4 weeks of treatment in the treatment group were higher （P＜0.05）， while SSA scores， PTT， and swallowing duration were lower （P＜0.05） than those in the control group at the same time. ConclusionCombined tongue three-needle acupuncture and acupoint application on Lianquan （CV 23） for patients with dysphagia after ischemic stroke can significantly improve swallowing activities， and its mechanism of action may be related to the improvement of the contraction ability and coordination of swallowing-related muscle groups.

Objective To explore the predictive value of inflammatory markers for stroke-associated pneumonia(SAP)in patients with acute ischemic stroke(AIS)based on the nomogram model.Methods According to whether pneumonia occurred,259 AIS patients were divided into SAP group(81 cases)and non-SAP group(178 cases).The clinical data of the two groups were compared.The systemic inflammatory response index(SIRI),systemic immunoinflammatory index(SII)and neutrophil to lymphocyte ratio(NLR)were calculated according to the formula.The variables with statistically significant differences were included in the multivariate binary Logistic regression model to screen out the independent risk factors for SAP in AIS patients.The independent risk factors were used to construct a predictive model,and the predictive ability of the two models,which only included traditional factors and included inflammatory indicators at the same time,was further compared from the aspects of discrimination,calibration,clinical practicability and so on.Reclassification analysis was used to evaluate the extent to which the nomogram model improved the predictive value of SAP risk in AIS patients.Results Compared with those in the non-SAP group,the rates of smoking,diabetes,dysphagia,leukocytes,neutrophils,lymphocytes,triglyceride level,NIHSS score on admission,SIRI,SII and NLR were significantly increased in the SAP group,and the rate of hypertension was decreased(all P＜0.05).Diabetes mellitus(OR =2.505,95%CI:1.070-5.850,P =0.034),dysphagia(OR =3.492,95%CI:1.501-8.119,P =0.004),NIHSS score on admission(OR = 1.310,95%CI:1.188-1.446,P＜0.001),SIRI(OR =2.417,95%CI:1.327-4.401,P =0.008),NLR(OR =1.434,95%CI:1.101-1.860,P =0.007)were independent risk factors for SAP in AIS patients.The area under the curve was 0.788(95%CI:0.725-0.852,P＜0.001)for the prediction model without inflammatory factors and 0.884(95%CI:0.838-0.930,P＜0.001)for the prediction model with independent risk factors.The calibration curve showed a good consistency between the predicted risk and the observed results.The decision curve showed that the model had a significant net benefit for predicting SAP.In addition,by calculating the net reclassification index(NRI)and the comprehensive discriminant improvement index(IDI),it was found that the nomogram model had a significant improvement in predicting the risk of SAP in AIS patients.Internal verification also proves the reliability of the nomogram model.Conclusions SIRI and NLR are independent predictors of SAP in AIS patients on admission.Adding SIRI and NLR to the traditional model can significantly improve the ability to identify the risk of SAP occurrence in AIS patients.

Objective:To investigate the characteristics of cortical morphology in children with attention defi-cit hyperactivity disorder(ADHD)and those with oppositional defiant disorder(ODD)from both categorical and dimensional analyses.Methods:A total of 72 children were enrolled,including 16 children with ADHD and ODD,20 children with ADHD without ODD,and 36 age-gender-matched normal children.The diagnoses were made ac-cording to the Diagnostic and Statistical Manual of Mental Disorders,Fourth Edition(DSM-Ⅳ)criteria.The Chi-nese Wechsler Intelligence Scale for Children(C-WISC)was used to access intelligence quotient.All subjects par-ticipated in the magnetic resonance imaging(MRI)scan.The features of cortical morphology were determined using FreeSurfer software.Results:Children with ADHD and ODD[(6 528.1±857.5)mm3 vs.(7 591.2±657.3)]and children with ADHD only[(6 867.2±41.3)mm3 vs.(7 591.2±657.3)mm3]had smaller volume in the left later-al superior temporal gyrus(P＜0.05)than controls.No difference was found between ADHD with ODD group and ADHD without ODD group.There was no correlation between the cortical volume of left lateral superior temporal gyrus and ODD symptoms.Conclusion:The reduced cortical volume of left lateral superior temporal gyrus may be an important indication of the abnormal brain structure of ADHD in children.And comorbid status of ODD dose not change this structural variation.

Objective To investigate the modulatory effect of Yulian Pills(composed of Coptidis Rhizoma and Euodiae Fructus)on splenic memory follicular T helper cell(mTfh)in mice with dextran sodium sulfate(DSS)-induced ulcerative colitis.Methods Forty BALB/c mice were randomly divided into normal group,model group,Yulian Pills group(0.5 g·kg-1)and Mesalazine group(0.3 g·kg-1),10 mice in each group.The mouse model of ulcerative colitis was induced by ad libitum drinking 3%DSS solution for 7 days.During the experiment,the mental state,faecal characteristics,blood in stool and body mass of the mice were recorded daily,and the length and mass of the colon were measured and the colon mass index was calculated;HE staining was used to observe the pathological and morphological changes of the colon tissue;ELISA was used to determine the expression levels of interleukin(IL)-6 and IL-15 in the colon tissues;flow cytometry was used to determine the mTfh cell subpopulation in the spleen tissue expression;Western Blot was used to determine the protein expression levels of Roquin-1,AMPK-α,p-AMPK-α in colon tissues.Results Compared with the normal group,the mice in the model group showed a significant decrease in body mass(P＜0.01),a significant shortening of colon length(P＜0.01),significant increase in colon mass(P＜0.05)and colon mass index(P＜0.01),and severe pathological damage to colon tissues;the expression levels of the pro-inflammatory cytokines IL-6 and IL-15 in the colon tissues were significantly increased(P＜0.01);cell expression levels of CD4+CCR7-CXCR5+CD62L+,CD4+CCR7+CXCR5+ GL7+,CD4+CCR7-CXCR5+GL7+ were significantly increased in spleen tissues(P＜0.01),whereas the expression level of CD4+CCR7+CXCR5+CD62L+ cell was significantly decreased(P＜0.01);and protein expression levels of Roquin-1,AMPK-α,p-AMPK-α were significantly reduced in the colonic tissues(P＜0.05).Compared with the model group,mice in the Yulian Pills group and Mesalazine group showed a significant increase in body mass(P＜0.05),a significant extension of colon length(P＜0.01),a significant reduction in colon mass(P＜0.05),a significant decrease in the colon mass index(P＜0.01),and a more obvious improvement in pathological damage of the colon tissues;a significant decrease in the expression levels of IL-6 and IL-15 in the colon tissues(P＜0.01);cell expression levels of CD4+CCR7-CXCR5+CD62L+,CD4+CCR7+CXCR5+GL7+,CD4+CCR7-CXCR5+GL7+ in splenic tissues was significantly reduced(P＜0.01),whereas the expression level of CD4+CCR7+CXCR5+CD62L+ cell was significantly increased(P＜0.01);the protein expression levels of Roquin-1,AMPK-α,and p-AMPK-α were significantly increased in colon tissues(P＜0.05,P＜0.01).Conclusion The therapeutic effect of Yulian Pills on DSS-induced ulcerative colitis mice can ameliorate the histopathological damage of colon,which may be related to the activation of the Roquin-1/MPK-α signalling pathway,the down-regulation of the expressions of inflammatory cytokines IL-6 and IL-15,and the modulation of the homeostasis of the mTfh cell subpopulation.

Objectives:To explore the spatial distribution characteristics, trend changes, and spatial clustering of esophageal cancer among residents in China at the county (city, district) scale, a spatial epidemiological approach was used, with the aim of providing localized evidence for the prevention and treatment of esophageal cancer in China.Methods:The data source was the incidence (crude rate) and mortality (crude rate) of esophageal cancer from 2005 to 2016 in the 2008-2019 edition of China Cancer Registration Annual Report published by the National Cancer Center. The Joinpoint model was used for time trend analysis. The tumor registration area in 2016 was selected as the study area for spatial feature analysis, with a total of 487 counties (cities and districts), covering 27.6% of the national population. Spatial autocorrelation analysis was performed to reveal spatial distribution characteristics by using Arcgis 10.6 software, and spatial scanning statistics was used to analyze spatial clustering characteristics by using SaTScan 9.5 software. The log-likelihood ratio ( LLR) and relative risk ( RR) were calculated in different windows, and the region with the largest LLR value represented the most likely cluster. Results:From 2005 to 2016, the incidence and mortality rate of esophageal cancer in China showed a trend of increasing at first and then decreasing. The incidence and mortality rate of esophageal cancer in 2016 were characterized by spatial positive correlation. High incidence and high mortality were mainly concentrated in the areas through which the Huaihe River flowed. The primary clusters (taking high incidence rate as an example LLR=6 374.41, RR=2.37, P＜0.001) were mainly distributed in Jiangsu, Anhui and Shandong in eastern China and eastern Henan and southern Hebei in central China, and secondary clusters (taking high incidence rate as an example LLR=1 971.19, RR=1.91, P＜0.001) in Gansu, Ningxia Hui Autonomous Region, Shaanxi, Sichuan and other central and western regions. Conclusions:The incidence and mortality of esophageal cancer in China have decreased since 2010. The disease burden of esophageal cancer has obvious spatial differences, and measures should be taken according to local conditions in high-risk cluster areas such as the Huaihe River basin.

Objective:To systematically review the predictive model for de novo stress urinary incontinence (de novo SUI) after pelvic organ prolapse (POP) surgery, with the aim of providing reference for preventing the occurrence of de novo SUI.Methods:Literature on the prediction model of de novo SUI after POP surgery was electronically retrieved in PubMed, Embase, Web of Science, Cochrane Library, China National Knowledge Infrastructure, WanFang, and VIP. The search period was from the establishment of the database to December 31, 2023, and the language was limited to Chinese and English. Two researchers independently screened literature, extracted data, and used the prediction model risk of bias assessment tool (PROBAST) to evaluate the quality of the models.Results:A total of 13 articles were included, including 13 de novo SUI risk prediction models. One literature was a prospective study, one literature was a secondary analysis of data, and the rest were retrospective studies. The area under the receiver operating characteristic curve in nine models ranged from 0.595 to 0.842, and the C-index of three models ranged from 0.710 to 0.738. Five models were not validated or only internally validated after construction. Six models were validated in one external population. The predictive performance of one model was validated in six external populations. The overall applicability of the 13 prediction models was good, but there was a certain risk of bias in all of them. Conclusions:There is a significant difference in the predictive performance of the de novo SUI risk prediction model after POP surgery, and the number is relatively small, indicating that it is still in the development stage. Future research should continuously optimize existing models and conduct external validation, and construct predictive models suitable for postoperative de novo SUI in POP patients in China.

Objective:To explore the characteristics of parental emotional regulation(ER)and its influence on the ER of children with attention deficit hyperactivity disorder(ADHD).Methods:A total of 140 children with ADHD meeting the Diagnostic and Statistical Manual of Mental Disorders,Fourth Edition(DSM-Ⅳ)criteria and their parents,68 normal controls and their parents were recruited.ER was assessed using the Difficulties in Emotion Regulation Scale(DERS),Emotion Regulation Questionnaire(ERQ)and Emotion Regulation Checklist(ERC).Re-sults:Higher scores of DERS in emotion regulation strategies,impulse control and goal-directed behavior were found in parents of children with ADHD compared with parents of normal controls(Ps＜0.05).The higher emo-tional lability(EL)of ERC and lower ER of ERC detected in children with ADHD were correlated with the emo-tion regulation strategies,impulse control and goal-directed behavior of their parents(Ps＜0.01).The mediation an-alyses suggested that ER in children with ADHD may mediate the relationship of parental emotion regulation strate-gies and parental impulse control with children's EL.Conclusion:Parents of children with ADHD may exhibit emo-tional dysregulation in multiple subdimensions which might affect emotional regulation and aggravate the emotional lability of children with ADHD.

Objective:To explore the characteristics of delay discounting and non-systematic response data in intertemporal choice of adults with attention deficit hyperactivity disorder(ADHD),and to explore the best data processing strategy for delay discounting task.Methods:Totally 108 adults with ADHD meeting the diagnostic cri-teria of the Diagnostic and Statistical Manual of Mental Health Disorder,Fifth Edition(DSM-5)and 87 gender matched normal controls were enrolled.ADHD symptoms were assessed using the ADHD Symptom Rating Scale,the delay discounting task was used to measure the delay discounting rate,and a model-free algorithm was used to i-dentify non-systematic response data.Results:There was no significant difference in the proportion of non-systemat-ic response data between ADHD group and normal control group(P＞0.05).In the data sets using different data screening strategies,the delay discounting rates were higher in the ADHD group than in the normal control group(Ps＜0.05).The delay discounting rates were positively correlated with the hyperactive impulse scores(r=0.24,P=0.001),the inattention scores(r=0.20,P＜0.01)and the total scores of ADHD symptom Rating Scale(r=0.22,P＜0.01).Conclusion:Adults with ADHD prefer to obtain immediate small rewards in intertemporal choice.The immediate preference of intertemporal choice may be mainly related to hyperactive impulsive symp-toms.Exclusion strategy of non-systematic response data may be more applicable to delay discount task research.
