ObjectiveTo establish an educational intervention framework of electronic picture books for children with autism spectrum disorder (ASD) based on Creative Problem Solving (CPS) model, and observe the effect on social function. MethodsElectronic picture books were designed using CPS model, including the program of reading, interactive animation design and associated artistic activities. From March to June, 2023, 24 children with mild to moderate ASD were recruited from Maanshan Institute of Special Education, and randomly assigned into experimental group 1 (CPS-based cognitive picture book interventions, n = 8), experimental group 2 (CPS-based social picture book interventions, n = 8) and control group (Bloom's Taxonomy-based picture book interventions, n = 8), and received the interventions for four weeks, with a total of twelve times. They were assessed with speech, social, perceptual and health behavior using Autism Treatment Evaluation Checklist (ATEC) before and after treatment, and the differences were calculated. ResultsThere was a significant difference among the groups in the social and perceptual scores differences (F > 4.344, P < 0.05) and a near-significant difference in the health behaviour score difference (F = 2.921, P = 0.076). Post Hoc test showed that the differences in social scores were higher in both experimental groups than in the control group (P < 0.05); the difference in perceptual scores was significantly higher in experimental group 1 than in experimental group 2 (P < 0.01), but there was no significant difference with the control group (P > 0.05); the difference in health behavior scores was higher in experimental group 2 than in the control (P < 0.05), and the difference in experimental group 1 was slightly higher than in the control group (P = 0.072). ConclusionElectronic picture book interventions based on the CPS model may be more effective in enhancing social, perceptual and health behavior in children with ASD, but there may be differences among models.

Objective:Migraine and tremor share some genetic mutation sites,and clinical studies have also confirmed their correlation.This study aims to explore the clinical and electrophysiological characteristics of migraine patients with concomitant tremor,and to analyze the relevant influential factors of tremor occurrence. Methods:We retrospectively analyzed the clinical data of 217 migraine patients who visited the Third Affiliated Hospital of Qiqihar Medical University from June 2022 to October 2023.The Clinical Rating Scale for Tremor(CRST),Numerical Rating Scale(NRS),Generalized Anxiety Disorder-7(GAD-7),and Patient Health Questionnaire-9(PHQ-9)were respectively used to assess the tremor symptoms,degree of headache,anxiety,and depression of patients.All patients underwent routine head MR scanning and electromyography examination,and were divided into a migraine with tremor group and a migraine without tremor group based on the electromyogram examination. Results:The migraine with tremor group and the migraine without tremor group were included 52 patients(23.96%)and 165 patients(76.04%),respectively.Compared with the migraine without tremor group,the migraine with tremor group had a longer course and duration of headache,higher frequency of headache attacks,higher NRS score,GAD-7 score,and PHQ-9 score,and fewer weekly physical exercises.The differences were statistically significant(all P<0.05).There were no statistically significant differences in the presence or absence of prodromal headache and white matter hyperintensities(WMHs)between the 2 groups(both P>0.05).The evaluation results of the CRST showed that out of 217 migraine patients,39 patients(17.97%)were accompanied by tremors.The electromyographic results showed that all 52 migraine patients with tremors had upper limb tremors,including 28 migraine patients with postural tremors and 24 migraine patients with static tremors.Compared with the migraine patients with static tremors,the migraine patients with postural tremors had lower average frequency,peak frequency,and headache onset frequency(all P<0.05).Multiple linear regression analysis showed that frequency of physical exercise,duration of illness,frequency of headache attacks,NRS score,GAD-7 score,and PHQ-9 score were risk factors for migraine patients with concomitant tremors(all P<0.05). Conclusion:Patients with migraine mainly experience upper limb postural tremors.Reduced physical exercise,long course of disease,long duration of headache,frequent headache attacks,severe headache,anxiety,and depression are risk factors for migraine patients with concomitant tremors.

Objective:To evaluate the diagnostic efficacy and practicality of the Jaundice color card (JCard) as a screening tool for neonatal jaundice.Methods:Following the standards for reporting of diagnostic accuracy studies (STARD) statement, a multicenter prospective study was conducted in 9 hospitals in China from October 2019 to September 2021. A total of 845 newborns who were admitted to the hospital or outpatient department for liver function testing due to their own diseases. The inclusion criteria were a gestational age of ≥35 weeks, a birth weight of ≥2 000 g, and an age of ≤28 days. The neonate′s parents used the JCard to measure jaundice at the neonate′s cheek. Within 2 hours of the JCard measurement, transcutaneous bilirubin (TcB) was measured with a JH20-1B device and total serum bilirubin (TSB) was detected. The Pearson′s correlation analysis, Bland-Altman plots and the receiver operating characteristic (ROC) curve were used for statistic analysis.Results:Out of the 854 newborns, 445 were male and 409 were female; 46 were born at 35-36 weeks of gestational age and 808 were born at ≥37 weeks of gestational age. Additionally, 432 cases were aged 0-3 days, 236 cases were aged 4-7 days, and 186 cases were aged 8-28 days. The TSB level was (227.4±89.6) μmol/L, with a range of 23.7-717.0 μmol/L. The JCard level was (221.4±77.0) μmol/L and the TcB level was (252.5±76.0) μmol/L. Both the JCard and TcB values showed good correlation ( r=0.77 and 0.80, respectively) and agreements (96.0% (820/854) and 95.2% (813/854) of samples fell within the 95% limits of agreement, respectively) with TSB. The JCard value of 12 had a sensitivity of 0.93 and specificity of 0.75 for identifying a TSB ≥205.2?μmol/L, and a sensitivity of 1.00 and specificity of 0.35 for identifying a TSB ≥342.0?μmol/L. The TcB value of 205.2?μmol/L had a sensitivity of 0.97 and specificity of 0.60 for identifying TSB levels of 205.2 μmol/L, and a sensitivity of 1.00 and specificity of 0.26 for identifying TSB levels of 342.0 μmol/L. The areas under the ROC curve (AUC) of JCard for identifying TSB levels of 153.9, 205.2, 256.5, and 342.0 μmol/L were 0.96, 0.92, 0.83, and 0.83, respectively. The AUC of TcB were 0.94, 0.91, 0.86, and 0.87, respectively. There were both no significant differences between the AUC of JCard and TcB in identifying TSB levels of 153.9 and 205.2 μmol/L (both P>0.05). However, the AUC of JCard were both lower than those of TcB in identifying TSB levels of 256.5 and 342.0 μmol/L (both P<0.05). Conclusions:JCard can be used to classify different levels of bilirubin, but its diagnostic efficacy decreases with increasing bilirubin levels. When TSB level are ≤205.2 μmol/L, its diagnostic efficacy is equivalent to that of the JH20-1B. To prevent the misdiagnosis of severe jaundice, it is recommended that parents use a low JCard score, such as 12, to identify severe hyperbilirubinemia (TSB ≥342.0 μmol/L).

Objective To investigate the expression and mechanism of long non-coding RNA (lncRNA) GHRLOS2 in colorectal cancer tissues and cells. Methods Real-time quantitative reverse transcription polymerase chain reaction (qRT-PCR) was used to detect the expression levels of GHRLOS2 and microRNA-33b-5p (miR-33b-5p) in colorectal cancer tissues or cells. Overexpressing of GHRLOS2 in HCT116 and SW480 colorectal cancer cell lines were constructed, and the effects of overexpression of GHRLOS2 on the migration and invasion abilities in HCT116 and SW480 cell lines were detected by wound healing assay and Transwell assay. Glucose content in cells of overexpressing GHRLOS2 and control cells was detected using a glucose detection kit. Western blot was used to detect the expression level of PCK1 protein in cells. The targeted binding relationship between miR-33b-5p and PCK1 was predicted based on bioinformatics methods. Results The qRT-PCR results showed that the expression level of GHRLOS2 in colorectal cancer tissue samples was lower than that in adjacent non-cancerous tissues, and was lower in colorectal cancer cells than that in normal colon epithelial cells (P < 0.05). The expression of GHRLOS2 was correlated with grade classification, staging, and lymph node metastasis (P < 0.05). The expression level of miR-33b-5p in colorectal cancer tissues was higher than that in corresponding adjacent non-cancerous tissues (P < 0.001). The results of wound healing assay, Transwell assay, and glucose content detection showed that overexpression of GHRLOS2 significantly inhibited the invasion, migration, and glucose metabolism of colorectal cancer cells. Overexpression of GHRLOS2 inhibited the expression level of miR-33b-5p; GHRLOS2 functioned as a molecular sponge for miR-33b-5p, and PCK1 was a target of miR-33b-5p; overexpression of GHRLOS2 competitively bound to miR-33b-5p, thereby promoting increased expression of PCK1. Conclusion The expression of GHRLOS2 is downregulated in colorectal cancer tissues and cells, and it may regulate the invasion, migration, and glucose metabolism of colorectal cancer cells through the miR-33b-5p/PCK1 pathway, making it a potential biological target for targeted therapy of colorectal cancer.

ObjectiveTo obtain the status of latent tuberculosis infection （LTBI） among tuberculosis （TB）-related health-care workers （HCWs） in Shanghai， and to explore the risk factors related to TB infection. MethodsA multi-center cross-sectional study was conducted by recruiting medical workers from multiple designated TB hospitals， centers for disease control and prevention， and community health service centers in Shanghai. Each subject was required to complete a questionnaire and to provide a blood sample for TB infection test. Univariate and multivariate analysis ware made in order to find risk factors relating to TB infection. ResultsA total of 165 medical workers were recruited， and the proportion of TB infection was 16.36% （95%CI： 11.49%‒22.76%）. Multivariate logistic analysis showed that clinical doctors and nurses （adjusted OR=9.756， 95%CI： 1.790‒53.188）， laboratory staffs （adjusted OR=78.975， 95%CI： 8.749‒712.918）， and nursing and cleaning workers （adjusted OR=89.920， 95%CI： 3.111‒2 598.930） had higher risk of TB infection. ConclusionThe overall LTBI prevalence among TB-related HCWs is low. However， working as doctors， nurses， laboratory staffs， nursing workers and cleaning workers are risk factors of TB infection. TB-related HCWs who work at hospitals are at risk of TB infection comparing to medical staffs who work outside hospitals.

新冠病毒感染疫情严重威胁着世界各国人民的生命健康。目前，对病毒感染的防治研究主要集中在抑制病毒与分子受体的结合上。AXL作为新发现的严重急性呼吸综合征冠状病毒2型（SARS-CoV-2）受体，在协助病毒感染人体呼吸系统中发挥着重要作用，是未来临床干预的潜在靶点。本研究对已发表的单细胞测序数据进行整理和分析，发现AXL在年轻人肺细胞中的表达水平明显高于老年人。人胚肺二倍体成纤维细胞（2BS）是衰老研究的公认细胞株。本文采用2BS细胞构建复制性细胞衰老模型，发现年轻细胞中AXL的蛋白水平明显高于衰老细胞，据此推测年轻人感染的风险可能更高，需要注意防护。我们发现一种羊栖菜褐藻多糖硫酸酯组分（SFW-3）可显著下调年轻2BS细胞中AXL的表达水平，表明SFW-3具有一定的抗SARS-CoV-2感染的研究价值，同时表明2BS细胞株也可作为潜在的SARS-CoV-2体外感染模型。

Background/Aims: Chemoresistance is a common event after cancer chemotherapy, which is associated with the deregulation of circular RNAs (circRNAs). The objective of this study was to clarify the role of circ-LDLRAD3 in cisplatin (DDP)-resistant gastric cancer (GC). Methods: The expression of circ-LDLRAD3, miR-588, and SRY-box transcription factor 5 (SOX5) mRNA was detected by quantitative real-time polymerase chain reaction. Cell viability and the half maximal inhibitory concentration (IC 50 ) value were measured by CCK8 assay. Cell proliferation was assessed by colony formation and EdU assays. Cell apoptosis and cell invasion were assessed by flow cytometry assay and transwell assay, respectively. The expression of SOX5 protein was detected by Western blotting. A xenograft model was established to verify the role of circ-LDLRAD3 in vivo. Exosomes were isolated by differential centrifugation and identified by transmission electron microscopy and the expression of exosome-related proteins. Results: circ-LDLRAD3 was overexpressed in DDP-resistant GC tissues and cells. circ-LDL-RAD3 knockdown decreased the IC 50 of DDP-resistant cells and suppressed cell proliferation, survival and invasion. miR-588 was a target of circ-LDLRAD3, and miR-588 inhibition attenuated the inhibition of DDP resistance, proliferation, survival and invasion in DDP-resistant GC cells caused by circ-LDLRAD3 knockdown. SOX5 was a target of miR-588, and the inhibition of the DDP resistance, proliferation, survival and invasion of DDP-resistant GC cells by miR-588 restoration was largely rescued SOX5 overexpression. circ-LDLRAD3 knockdown inhibited DDP resistance and tumor growth in vivo. circ-LDLRAD3 was overexpressed in exosomes isolated from DDP-resistant GC cells. Conclusions circ-LDLRAD3 knockdown reduced DDP resistance and blocked the malignant development of DDP-resistant GC by modulating the miR-588/SOX5 pathway.

Objective:To analyze the status quo, trend and influencing factors of patient satisfaction in tertiary maternity and child hospitals in China.Methods:Based on the survey results of five round third-party evaluations of the China Healthcare Improvement Initiative from 2016 to 2021, descriptive trend analysis was conducted on the satisfaction index in tertiary maternity and child hospitals, and the influencing factors of satisfaction were analyzed based on the results of the fifth evaluation.Results:Compared with the first round, the overall patient satisfaction in tertiary maternity and child hospitals in the fifth round was improved(inpatient: from 95.7% to 98.0%; outpatient: from 87.8% to 94.9%). Outpatient satisfaction varied significantly among gender, hospitals of different types, education level, types of treatment, medical insurance and doctors′ titles( P<0.05). Outpatient satisfaction in local hospitals was 1.502 times higher than that in hospitals under the National Health Commission. The satisfaction of referrals was 0.259 times lower than that of patients who were admitted directly. Inpatient satisfaction varied significantly among department, hospitals of different regions, household registration type and whether the admission was delayed due to the COVID-19 epidemic( P<0.05). The satisfaction of inpatients in medical ward and surgical ward was respectively 0.202 and 0.298 times lower than that of inpatients in pediatric ward. Inpatient satisfaction at the central regions was 3.311 times higher than that at the eastern regions. Conclusions:The overall patient satisfaction in tertiary maternity and child hospitals in China is improving. In the future, we should pay more attention to the hospital environment, humanistic care and other non-medical service dimensions with low satisfaction, so as to further improve the medical experience of patients in maternity and child hospitals.

The incidence of intrahepatic cholangiocarcinoma (ICC) has been increasing year by year. For most patients, surgical resection is not suitable when they are diagnosed as ICC. Conventional chemotherapy and radiotherapy are not effective for the long-term survival rate of ICC patients and lead to the poor overall prognosis. In recent years, with the deepening understanding about the molecular mechanism of biliary malignant tumors, some key genes and signaling pathways related to the pathogenesis of ICC have been identified, providing new ideas for the targeted therapy. In this paper, major molecular mechanisms and targeted therapies of ICC are reviewed.

Objective To discuss the correlation between gastrointestinal symptoms concomitant with chronic migraine and sleep disorders,anxiety and depression.Methods Self-rating Anxiety Scale (SAS),Self-rating Depression Scale (SDS),Pittsburgh Sleep Quality Index (PSQI) and Gastrointestinal Symptom Rating Scale (GSRS) were adopted to conduct comparative analysis on gastrointestinal symptoms,anxiety,depression,sleep disorders,and related risk factors in 151 chronic migraine patients who conformed to International Headache Society International Classification of Headache Diseases-Ⅱ diagnostic code and 151 healthy controls in the Third Affiliated Hospital of Qiqihar Medical University from January 2015 to December 2017.Results PSQI scores (8.46±2.54 vs 4.53±1.95,t=2.913,P＜0.05),SAS scores (53.24± 11.66 vs 39.58±8.63,t=3.112,P＜0.05),SDS scores (51.09±8.80 vs 36.11±5.74,t=3.520,P＜0.05),and GSRS scores (4.53 (3.74,5.32) vs 1.29 (0.73,1.31),Z=30.804,P＜0.05) were all higher in migraine patients than that in healthy controls,and the differences were all statistically significant.In chronic migraine patients,139 (92.05％) had one gastrointestinal symptom at least,and the overall incidence of each gastrointestinal symptom was abdominal distension (60 cases,39.74％),exhaust increase (51 cases,33.77％),and endless defecation (43 cases,28.48％),etc.,in turn.Multiple regression analysis showed that headache degree,frequency,PSQI scores,SAS scores,and SDS scores were the main risk factors of gastrointestinal symptoms concomitant with chronic migraine.GSRS scores of chronic migraine patients presented positive correlation with PSQI scores (r=0.65,P=0.000),SAS scores (r=0.42,P=0.000),and SDS scores (r=0.48,P=0.000),respectively.Conclusion Chronic migraine patients are easy to be accompanied with gastrointestinal symptoms,and headache degree and frequency,sleep disorders,depression and anxiety are the main risk factors of concomitant gastrointestinal symptoms.
