ObjectiveBased on functional near-infrared spectroscopy (fNIRS), we investigated the brain activity characteristics of gross motor tasks in children with autism spectrum disorder (ASD) and motor dysfunctions (MDs) to provide a theoretical basis for further understanding the mechanism of MDs in children with ASD and designing targeted intervention programs from a central perspective. MethodsAccording to the inclusion and exclusion criteria, 48 children with ASD accompanied by MDs were recruited into the ASD group and 40 children with typically developing (TD) into the TD group. The fNIRS device was used to collect the information of blood oxygen changes in the cortical motor-related brain regions during single-handed bag throwing and tiptoe walking, and the differences in brain activation and functional connectivity between the two groups of children were analyzed from the perspective of brain activation and functional connectivity. ResultsCompared to the TD group, in the object manipulative motor task (one-handed bag throwing), the ASD group showed significantly reduced activation in both left sensorimotor cortex (SMC) and right secondary visual cortex (V2) (P<0.05), whereas the right pre-motor and supplementary motor cortex (PMC&SMA) had significantly higher activation (P<0.01) and showed bilateral brain region activity; in terms of brain functional integration, there was a significant decrease in the strength of brain functional connectivity (P<0.05) and was mainly associated with dorsolateral prefrontal cortex (DLPFC) and V2. In the body stability motor task (tiptoe walking), the ASD group had significantly higher activation in motor-related brain regions such as the DLPFC, SMC, and PMC&SMA (P<0.05) and showed bilateral brain region activity; in terms of brain functional integration, the ASD group had lower strength of brain functional connectivity (P<0.05) and was mainly associated with PMC&SMA and V2. ConclusionChildren with ASD exhibit abnormal brain functional activity characteristics specific to different gross motor tasks in object manipulative and body stability, reflecting insufficient or excessive compensatory activation of local brain regions and impaired cross-regions integration, which may be a potential reason for the poorer gross motor performance of children with ASD, and meanwhile provides data support for further unraveling the mechanisms underlying the occurrence of MDs in the context of ASD and designing targeted intervention programs from a central perspective.

Aim To investigate the changes in the proliferation and apoptosis of Siha cells after knocking down Rho GTPase-activating protein 30(ARHGAP30).Methods After designing specific shARHGAP30 primers and connecting them to the pLKO.1 vector,we transformed them into Escherichia coli competent cells,then co-transfecting them with lentiviral helper plasmids into HEK-293T cells.We collected and filtered cell supernatant to obtain the vi-rus to infect Siha cells.RT-qPCR and Western blot were used to detect knockdown efficiency,as well as changes in the expression of Bax and Bcl-2 after trans-fection.The CCK-8 method was employed to measure the proliferation level of cells after knockdown.Results After successful construction of a lentiviral plasmid with knockdown of the ARHGAP30 gene and establish-ment of stably transfected Siha cells,ARHGAP30 tran-scription and translation(P＜0.01)in Siha cells de-creased,Bax/Bcl-2 significantly decreased(P＜0.01),indicating decreased apoptosis and increased cell proliferation(P＜0.01).Conclusions This study suggests the involvement of ARHGAP30 in the proliferation and apoptosis of Siha cells,and regulating the ARHGAP30 gene may interfere with the occurrence and development of cervical cancer.

Objective To investigate the value of optical coherence tomography(OCT)in predicting the risk of major adverse cardiovascular events(MACE)in patients of acute coronary syndrome(ACS).Methods Four hundred and forth-eight ACS patients admitted to the First Affiliated Hospital of Xinjiang Medical University who underwent percutaneous coronary intervention(PCI)and OCT from February 2015 to February 2022 were selected as the study subjects.We found 749 non-culprit coronary lesions.And follow up the patients,median follow-up was 5 years[interquartile interval(IQR):3-7 years].Kaplan-meier was used to estimate the cumulative incidence of MACE,multivariate Cox regression was used to analyze the risk of MACE with OCT parameters non-culprit coronary lesions,and receiver operating characteristic(ROC)curve was used to evaluate the predictive value of OCT parameters for MACE in non-culprit coronary lesions.Results A total of 749 non-culprit coronary lesions were detected,and 41 MACE cases were caused by non-culprit coronary lesions imaged by OCT.Compared with plaques without thin-cap fibroatheroma(TCFA)and minimal lumen area(MLA)＜3.5 mm2,the incidence of MACE was significantly associated with vulnerable plaques with TCFA and MLA＜3.5 mm2(33％vs.3％,HR 13.62,95％CI 6.71-27.65,P＜0.001).Multivariate Cox regression analysis showed that larger maximum lipid arc(HR 1.02,95％CI 1.01-1.03,P＜0.001),smaller maximum lipid cap thickness(HR 0.97,95％CI 0.96-0.99,P＜0.001)and MLA(HR 0.31,95％CI 0.18-0.55,P＜0.001)were independent risk factors for MACE.The area under ROC curve(AUC)of the thinnest fiber cap thickness for predicting MACE occurrence was 0.858(95％CI 0.802-0.913),and the optimal cutoff value was 66.5 μm.The AUC of maximum lipid arc for predicting MACE occurrence was 0.853(95％CI 0.786-0.920),and the optimal cut-off value was 180.35°.The AUC of MLA for predicting MACE was 0.821(95％CI 0.766-0.876),and the optimal cutoff was 3.575 mm2.Conclusions The non-culprit coronary lesions with TCFA and MLA＜3.5 mm2 were significantly associated with an increased risk of subsequent MACE development at the lesion level,and OCT imaging helps early identification of the risk of MACE development in non-culprit coronary lesions in patients of ACS.

The aim of this study was to clarify the genetic diversity and population history of Ixodes persulcatus in some ar-eas of Inner Mongolia in order to provide accurate data for effective vector control programs and reveal the transmission mecha-nism.Samples were collected in 10 areas of Inner Mongolia during the active tick season(April 2021-July 2023)using the flag-dragging and manual sampling methods.The 16S rRNA and COI gene were sequenced to clarify genetic diversity of I.per-sulcatus.The positivity rates for the COI gene and 16S rRNA were 90.00％and 98.33％respectively.Overall,18 and 15 haplotypes were identified for the COI gene and 16S rRNA,respectively,with a total haplotype diversity＞0.762 and total nucleotide diversity＜0.005.The Tajima's values and Fu's Fs were negative for significance.A nucleotide mismatch map was shown as a single peak.The genetic differentiation index FST of the population indicates a small degree of genetic differ-entiation of the population,while analysis of molecular vari-ance indicates that the variation within populations was greater than between populations.Phylogenetic tree and haplotype network plots showed confounding distributions between hap-lotypes.I.persulcatus from the Hinggan League and Hulun-buir regions can adapt to environmental changes and possess abundant genetic diversity.Genetic differentiation is mainly concentrated within the population and no geographical isolation was observed.

Objective:To investigate the protective effect of endogenous ω-3 polyunsaturated fatty acid(PUFA)against cisplatin-induced myelosuppression and the mechanism of reducing apoptosis in bone marrow nucleated cells using mfat-1 transgenic mice.Methods:The experimental animals were divided into 4 groups:wild-type mice normal control group,mfat-1 transgenic mice normal control group,wild-type mice model group and mfat-1 transgenic mice model group.The mice in the model group were injected intraperitoneally with 7.5 mg/kg cisplatin on day 0 and day 7 to construct a myelosuppression model,while the mice in the normal control group were injected intraperitoneally with an equal amount of saline,and their status was observed and their body weight was measured daily.Peripheral blood was taken after 14 day for routine blood analysis,and the content and proportion of PUFA in peripheral blood were detected using gas chromatography.Bone marrow nucleated cells in the femur of mice were counted.The histopathological changes in bone marrow were observed by histopathological staining.The apoptosis of nucleated cells and the expression level changes of apoptosis-related genes in the bone marrow of mice were detected by flow cytometry and fluorescence quantitative PCR.Results:Compared with wild-type mice,mfat-1 transgenic mice showed significantly increased levels of ω-3 PUFA in peripheral blood and greater tolerance to cisplatin.Peripheral blood analysis showed that endogenous ω-3 PUFA promoted the recovery of leukocytes,erythrocytes,platelets and haemoglobin in peripheral blood of myelosuppressed mice.The results of HE staining showed that endogenous ω-3 PUFA significantly improved the structural damage of bone marrow tissue induced by cisplatin.Flow cytometry and PCR showed that,compared with wild-type mice model group,the apoptosis rate of bone marrow nucleated cells in mfat-1 transgenic mice was significantly reduced(P＜0.001),and the expression of anti-apoptotic genes Bcl-2 mRNA was significantly increased(P＜0.01),while the expressions of pro-apoptotic genes Bax and Bak mRNA were significantly reduced(P＜0.001,P＜0.05).Conclusion:Endogenous ω-3 PUFA can reduce cisplatin-induced apoptosis in bone marrow nucleated cells,increase the number of peripheral blood cells and exert a protective effect against cisplatin-induced myelosuppression by regulating the expression of apoptosis-related genes.

Objectives:To explore the imaging features of patients with isolated left ventricular apical hypoplasia(ILVAH). Methods:Twelve patients diagnosed with ILVAH(ILVAH group)in our hospital from April 2018 to August 2023 were enrolled,and all of them received transthoracic echocardiography(TTE)examination;9 patients underwent CMR examination;and 1 patient underwent CT examination.Clinical data and imaging characteristics of the patients were analyzed.At the same time,twelve healthy age and sex matched participants who underwent physical examination in the same period were selected as the control group. Results:TTE showed that:compared with the control group,the left ventricular transverse diameter([46.3±5.7]mm vs.[57.8±12.6]mm)and right ventricular long diameter([62.0±4.2]mm vs.[73.6±6.4]mm)were larger in the ILVAH group(P＜0.05),the left ventricular long diameter([63.0±3.5]mm vs.[53.4±8.2]mm)was smaller(P＜0.05).There was no significant difference in right ventricular transverse diameter between the two groups(P＞0.05).The interventricular septum was convex to the right ventricle,and the thickness at the apex was(5.2±2.0)mm in the ILVAH group.The papillary muscles were all attached to the flat left ventricular apex.Among the 9 patients who underwent CMR examination,adipose tissue replacement was found in the left ventricular apex in 7 out of the 9 patients,and endocardial fibrosis was found in 2 out of the 9 patients. Conclusions:The clinical presentation of ILVAH is non-specific,but there are specific imaging manifestations that may help improve the understanding of the disease.

Objectives:To evaluate the diagnostic value of echocardiography in unroofed coronary sinus syndrome(UCSS)with endocardial cushion defect(ECD). Methods:The echocardiographic data of 43 patients of UCSS with ECD who underwent surgical treatment in our hospital from July 2017 to May 2022 were retrospectively analyzed.The diagnostic accuracy was evaluated by comparing the echocardiographic findings with the intraoperative exploration results. Results:According to Kirklin and Barratt-Boyes classification,there were 26 cases of type Ⅰ(60.5%),9 cases of type Ⅱ(20.9%),2 cases of type Ⅲ(4.7%),4 cases of type Ⅳ(9.3%),and 2 cases of type Ⅲ combined with type Ⅳ(4.7%).There were 26 cases(60.5%)of partial ECD,7 cases(16.3%)of intermediate ECD,10 cases(23.3%)of total ECD.Twenty two cases(51.2%)were associated with single atrium.Twenty seven cases(62.8%)were associated with persistent left superior vena cava(PLSVC).Other coexisting complicated malformations were as follows:2 cases of double outlet of right ventricle,1 case of pulmonary atresia,1 case of total anomalous pulmonary venous connection,and 1 case of aplenia syndrome.The coexisting simple malformations included 4 cases of ostium secundum atrial septal defect,2 cases of ventricular septal defect,3 cases of patent ductus arterial,and 6 cases of patent foramen ovale.Other abnormalities included 5 cases of absence of hepatic segment of inferior vena cava,1 case of hypoplasia of right superior vena cava,1 case of absence of right superior vena cava,3 cases of cor triatriatum,1 case of isolated levocardia,1 case of mirror image dextrocardia,4 cases of right aortic arch.Of the 43 patients,30(69.8%)were correctly diagnosed by preoperative echocardiography and 13(30.2%)by intraoperative exploration.UCSS was misdiagnosed as inferior vena cava type sinus septal defect and PLSVC was missed in 1 case.UCSS was missed in 12 cases,and PLSVC was missed in 3 cases of them. Conclusions:Diagnosis UCSS with ECD by echocardiography is valuable and challenging.It is necessary to strengthen the understanding of the embryonic development and pathological anatomy characteristics of these malformations to improve the diagnostic accuracy.
