Objective To explore the content and the psychometric properties of assessment tools used for evaluating functioning and adaptive behavior in school-age children with intellectual and developmental disabilities within educational settings. Methods The most used assessment tools included Vineland Adaptive Behavior Scales(VABS),Supports Intensity Scale for Children(SIS-C),Strengths and Difficulties Questionnaire(SDQ)and Repetitive Behavior Scale-Revised(RBS-R),for assessing functioning and adaptive behavior children with intellectual and developmental disabili-ties.Employing the framework and methods of the International Classification of Functioning,Disability,and Health(ICF),this research encoded and categorized the assessment dimensions and items of the four tools,and explored their psychometric properties. Results VABS's assessment content was solely focused on activities and participation,including speaking(d330),con-versation(d350),toileting(d530),eating(d550),drinking(d560),basic interpersonal interactions(d710),com-plex interpersonal interactions(d720),changing and maintaining body positions(d410-d429),carrying,moving and handing objects(d430-d449),and walking and moving(d450-d469).SIS-C assessed activities and participa-tion,and environmental factors,including washing oneself(d510),caring for body parts(d520),community life(d910),using transportation(d470),school education(d820),basic learning(d130-d159),looking after one's health(d570),basic interpersonal interactions(d710),and products and technology for education(e130).SDQ fo-cused on body functions,and activities and participation,including emotional functions(b152),global psychoso-cial functions(b122),attention functions(b140),and basic interpersonal interactions(d710).RBS-R focused on body functions,and activities and participation,including involuntary movement reaction functions(b755),invol-untary movement functions(b765),looking after one's health(d570),energy and drive functions(b130),under-taking a single task(d210),carrying out daily routine(d230),attention functions(b140),and handling stress and other psychological demands(d240).VABS was characterized by good specificity and excellent sensitivity.SIS-C demonstrated very good internal consistency,reliability and validity.SDQ was good in internal consistency,with excellent credibility and validity.RBS-R showed good internal consistency,reliability and validity. Conclusion SDQ and RBS-R cover both body functions,and activities and participation,SIS-C covers activity and par-ticipation,and environmental factors,while VABS solely assesses activities and participation.In terms of body functions,the assessment items primarily focus on mental functions(b130-b189)and movement functions(b750-b799).For activities and participation,the tools assess content across eight domains of functioning.Regarding en-vironmental factors,the assessment content mainly includes products and technology for education(e130),as well as design,construction and building products and technology of buildings for public use(e150).VABS,SIS-C,SDQ,and RBS-R are all norm-referenced measures,with moderate to excellent internal consistency,and good to excellent reliability and validity.

ObjectiveTo observe the effect of Coptidis Rhizoma and Ophiopogonis Radix on renal tissue injury and epidermal growth factor receptor （EGFR）/phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt） signaling pathway in rats with diabetic nephropathy （DN） and explore its possible mechanism of delaying DN. MethodThirty-six male Wistar rats were randomly divided into a normal group （6 rats） and a model group （30 rats）. The model group was fed with a high-fat and high-sugar diet combined with streptozotocin （STZ） to establish a rat model of type 2 diabetes. After the successful preparation of the model， the rats were randomly divided into the model group， low， medium， and high dose groups of Coptidis Rhizoma and Ophiopogonis Radix （100， 200， 400 mg·kg^-1）， and metformin group （200 mg·kg^-1）. After administration， the levels of fasting blood glucose （FBG）， 24 h urine protein （24 h-UTP）， creatinine （SCr）， urea nitrogen （BUN）， and uric acid （UA） were detected. Hematoxylin-eosin （HE） staining and Masson staining were used to observe the pathological changes of renal tissue in rats. Western blot and Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） were used to detect the related protein expression of EGFR， PI3K， and Akt and their mRNA expression levels in the renal tissue of rats in each group. ResultsCompared with the normal group， the levels of FBG， SCr， BUN， UA， 24 h-UTP， and kidney index in the model group were significantly increased （P<0.01）， most renal tubular epithelial cells were necrotic， and the content of collagen in glomeruli was significantly increased （P<0.01）. Compared with the model group， the above indexes of rats in each administration group were improved to varying degrees. The FBG， SCr， BUN， UA， 24 h-UTP， and kidney index of rats in each dose group and metformin group were significantly decreased （P<0.01， P<0.05）. The necrosis degree of renal tubular epithelial cells was reduced， and the fibrosis area was decreased （P<0.01）. There related protein and mRNA expressions of EGFR， PI3K， and Akt were significantly increased （P<0.05， P<0.01）. ConclusionCoptidis Rhizoma and Ophiopogonis Radix can alleviate renal tissue injury in rats with DN， and their mechanism may be related to the regulation of the EGFR/PI3K/Akt signaling pathway.

Objective To explore the intrinsic connectivity alterations of brain-wide functional networks in patient with trigeminal neuralgia(TN)via combining resting-state functional magnetic resonance imaging(rs-fMRI)and graph theory methods.Methods A total of 41 patients with TN(TN group)and 41 healthy controls(HC)(HC group)were recruited,and differences in network topologyat-tributes and correlations with clinical variables were analyzed between the two groups.Results Both groups met the σ standard.The global efficiency(Eg)of TN group was lower than that of HC group(P＜0.05),whereas the λ of TN group was higher than that of HC group(P＜0.05).The node efficiency(Ne)of bilateral rectus gyrus and bilateral pallidum of TN group were significantly higher than those of HC group,while the Ne of left supraparietal gyrus,left angular gyrus,left post-central gyrus,bilateral marginal supraparietal gyrus,and left caudate nucleus of TN group were significantly lower than those of HC group(P＜0.05).The local efficiency(Eloc)of the TN group was negatively correlated with the visual analogue scale(VAS)score(P＜0.05),the clustering coefficient(Cp)of the TN group was negatively correlated with the short-form McGill pain questionnaire(SF-MPQ)sensory score(P＜0.05),and the Ne of right rectus gyrus of the TN group was positively correlated with the disease duration(P＜0.05).Conclusion The TN group retain σ,but the overall information transfer efficiency of the brain is reduced and functional integration is diminished.Several brain regions in the TN group has abnormal Ne,which provide an objective basis for altered brain functional networks in TN.

Nowadays potential preclinical drugs for the treatment of nonalcoholic steatohepatitis (NASH) have failed to achieve expected therapeutic efficacy because the pathogenic mechanisms are underestimated. Inactive rhomboid protein 2 (IRHOM2), a promising target for treatment of inflammation-related diseases, contributes to deregulated hepatocyte metabolism-associated nonalcoholic steatohepatitis (NASH) progression. However, the molecular mechanism underlying Irhom2 regulation is still not completely understood. In this work, we identify the ubiquitin-specific protease 13 (USP13) as a critical and novel endogenous blocker of IRHOM2, and we also indicate that USP13 is an IRHOM2-interacting protein that catalyzes deubiquitination of Irhom2 in hepatocytes. Hepatocyte-specific loss of the Usp13 disrupts liver metabolic homeostasis, followed by glycometabolic disorder, lipid deposition, increased inflammation, and markedly promotes NASH development. Conversely, transgenic mice with Usp13 overexpression, lentivirus (LV)- or adeno-associated virus (AAV)-driven Usp13 gene therapeutics mitigates NASH in 3 models of rodent. Mechanistically, in response to metabolic stresses, USP13 directly interacts with IRHOM2 and removes its K63-linked ubiquitination induced by ubiquitin-conjugating enzyme E2N (UBC13), a ubiquitin E2 conjugating enzyme, and thus prevents its activation of downstream cascade pathway. USP13 is a potential treatment target for NASH therapy by targeting the Irhom2 signaling pathway.

Objective:To explore the effect of probiotics on the cognitive function of patients with schizophrenia.Methods:100 schizophrenic patients admitted to Shanghai Jinshan District Mental Health Center from January 2019 to January 2021 were randomly divided into the conventional group (treated with atypical antipsychotics combined with placebo, 50 cases) and the intervention group (treated with atypical antipsychotics combined with probiotics, 50 cases). Before treatment and 3 months after treatment, the feces of the patients were taken for DNA detection to compare the composition of intestinal flora. The cognitive function of the patients was assessed by the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS), and the mental state of the patients was assessed by the Positive and Negative Symptom Scale(PANSS). The incidence of adverse drug reactions was compared between the two groups.Results:Before treatment, the relative abundance of Fusobacteria, Proteus and Actinobacteria in the two groups had no statistical significant difference (all P>0.05); After 3 months of treatment, the relative abundance of Fusobacteria, Proteus and Actinobacteria in the two groups decreased compared with that before treatment, and the decline was more significant in the intervention group (all P<0.05). Before treatment, there was no significant difference in immediate memory, visual span, speech function, attention function, delayed memory and RBANS between the two groups (all P>0.05); After 3 months of treatment, the scores of immediate memory, visual span, speech function, attention function, delayed memory and RBANS in the two groups were higher than those before treatment, and the increase was more significant in the intervention group (all P<0.05). Before treatment, there was no significant difference in PANSS scores between the two groups ( P>0.05); After 3 months of treatment, PANSS scores in both groups decreased compared with those before treatment, and the decrease degree in the intervention group was higher than that in the conventional group (all P<0.05). During the three months of treatment, there was no significant difference in the incidence of adverse drug reactions between the two groups ( P>0.05). Conclusions:Probiotics are used in adjuvant therapy for patients with schizophrenia, which can regulate the patients′ intestinal flora, improve patients′ cognitive function and mental disorders, and do not increase the incidence of adverse drug reactions. They have significant clinical efficacy and high treatment safety.

Objective: To detect varicella-zoster virus ( VZV ) antibody levels among children aged 1 to 12 years in Lu'an City, Anhui Province, so as to provide insights into perfection of the varicella immunization strategy. Methods: Children aged 1 to 12 years were recruited from Lu'an City using the stratified random sampling method from July 2018 to February 2019, and subjects' demographics were collected using questionnaires. The inoculation of varicella vaccines was retrieved through the Anhui Immunization Information Management System or review of preventive immunization certificates, and the serum VZV IgG antibody was detected using enzyme-linked immunosorbent assay ( ELISA ). The seroprevalence and geometric mean concentration of the VZV-IgG antibody were estimated, and the changes of serum the VZV-IgG antibody levels were analyzed at different time intervals following varicella vaccination. Results: Totally 734 children were surveyed, with a mean age of ( 6.94±2.95 ) years, and the subjects included 412 boys ( 56.13% ) and 322 girls ( 43.87% ). There were 514 children ( 70.03% ) with a history of varicella vaccination, including 501 children ( 68.26% ) with one dose of varicella vaccine and 13 children ( 1.77% ) with two doses. There were 297 children ( 40.46% ) positive for VZV-IgG antibody, with seroprevalence of 40.46%, and the GMC of VZV-IgG antibody was 74.97 ( 95%CI: 65.55-85.75 ) mIU/mL. The seroprevalence of the VZV-IgG antibody were 34.55%, 42.91%, and 46.15% among the unvaccinated children and children receiving one dose and two doses of varicella vaccine, with the GMCs of 53.04, 86.31 and 114.46 mIU/mL, respectively. The mean time interval between inoculation of the last dose of varicella vaccine and blood sample collection was ( 5.21±2.79 ) years, and the lowest seroprevalene (31.48%) and GMC of the VZV-IgG antibody (49.96 mIU/mL) were found 4 years after inoculation of varicella vaccine. Conclusions The serum VZV-IgG antibody level is low among children aged 1 to 12 years in Lu'an City, and the seroprevalence of the VZV-IgG antibody is affected by age and doses of varicella vaccine. A 2-dose schedule of varicella vaccine is recommended for children.

Objective: To analyze the correlations between intraoperative ultrasound and MRI metrics of the spinal cord in degenerative cervical myelopathy and identify novel potential predictive ultrasonic indicators of neurological recovery for degenerative cervical myelopathy. Materials and Methods: Twenty-two patients who underwent French-door laminoplasty for multilevel degenerative cervical myelopathy were followed up for 12 months. The Japanese Orthopedic Association (JOA) scores were assessed preoperatively and 12 months postoperatively. Maximum spinal cord compression and compression rates were measured and calculated using both intraoperative ultrasound imaging and preoperative T2-weight (T2W) MRI. Signal change rates of the spinal cord on preoperative T2W MRI and gray value ratios of dorsal and ventral spinal cord hyperechogenicity on intraoperative ultrasound imaging were measured and calculated. Correlations between intraoperative ultrasound metrics, MRI metrics, and the recovery rate JOA scores were analyzed using Spearman correlation analysis. Results: The postoperative JOA scores improved significantly, with a mean recovery rate of 65.0 ± 20.3% (p < 0.001). No significant correlations were found between the operative ultrasound metrics and MRI metrics. The gray value ratios of the spinal cord hyperechogenicity was negatively correlated with the recovery rate of JOA scores (ρ = -0.638, p = 0.001), while the ventral and dorsal gray value ratios of spinal cord hyperechogenicity were negatively correlated with the recovery rate of JOA-motor scores (ρ = -0.582, p = 0.004) and JOA-sensory scores (ρ = -0.452, p = 0.035), respectively. The dorsal gray value ratio was significantly higher than the ventral gray value ratio (p < 0.001), while the recovery rate of JOA-motor scores was better than that of JOA-sensory scores at 12 months post-surgery (p = 0.028). Conclusion For degenerative cervical myelopathy, the correlations between intraoperative ultrasound and preoperative T2W MRI metrics were not significant. Gray value ratios of the spinal cord hyperechogenicity and dorsal and ventral spinal cord hyperechogenicity were significantly correlated with neurological recovery at 12 months postoperatively.

Objective:To compare the clinical utility of 18F-fibroblast activating protein inhibitor (FAPI)-42 and 18F-fluorodeoxyglucose (FDG) PET/CT imaging in newly diagnosed lung cancer patients. Methods:From May 2020 to September 2021, the images of 43 lung cancer patients (32 males, 11 females, age: 37-80 years) who pathologically confirmed and received 18F-FDG and 18F-FAPI-42 PET/CT within 2 weeks in the First Affiliated Hospital of Guangzhou Medical University were prospectively analyzed. The maximum standardized uptake value (SUV max) of 18F-FDG and 18F-FAPI-42 and the number of lesions detected by 2 imaging methods were compared by using paired t test and Wilcoxon rank sum test. Results:The 43 newly diagnosed lung cancer patients included 35 adenocarcinoma, 2 squamous cell carcinoma, 4 small cell lung cancer, and 2 high-grade neuroendocrine tumors. 18F-FAPI-42 had a very high tumor uptake (SUV max: 12.24±3.97) and lesion detection rate (positive rate: 100%(37/37)) in primary lung adenocarcinoma and squamous cell carcinoma. The uptake of 18F-FAPI-42 in lymph node (10.13±5.43), pleura (6.75(4.96, 8.58)) and bone lesion (7.18(4.33, 9.66)) were significantly higher than those of 18F-FDG (6.35±3.30, 2.69(1.81, 5.00), 4.38(2.96, 6.36); t=12.19, z values: 5.47, 5.79, all P<0.001). In lung adenocarcinoma and squamous cell carcinoma, although the uptake of 18F-FAPI-42 in brain metastases was significantly lower than that of 18F-FDG (0.72(0.15, 1.82) vs 6.53(4.65, 9.34); z=6.42, P<0.001), the tumor/background (T/B) ratio was significantly higher than that of 18F-FDG (3.54(1.15, 14.88) vs 0.96(0.77, 1.04); z=6.05, P<0.001). In lung adenocarcinoma and squamous cell carcinoma, the number of lesions detected by 18F-FAPI-42 PET/CT was significantly more than that of 18F-FDG (lymph node: 6.0(2.3, 11.5) vs 4.5(2.0, 10.8); brain: 2.0(1.0, 3.0) vs 0.0(0.0, 0.0); pleura: 6.0(2.8, 10.0) vs 4.0(0.8, 5.5); z values: 2.16, 3.10, 2.04, all P<0.05). However, in high-grade neuroendocrine tumors and small cell lung cancer, the SUV max of 18F-FAPI-42 in primary lesions (8.05±2.60), lymph node lesions (5.98±2.21) and brain lesions (0.44(0.13, 0.82)) were lower than those of 18F-FDG (16.28±5.17, 12.30±5.47, 4.94(4.84, 6.25); t values: 3.58, 7.52, z=3.06, all P<0.05). Conclusions:In lung adenocarcinoma and squamous cell carcinoma, 18F-FAPI-42 has a very high tumor uptake and lesion detection rate in primary tumor. In addition, compared with 18F-FDG PET/CT, 18F-FAPI-42 PET/CT shows clearer tumor contours and more lesions. Therefore, 18F-FAPI-42 is more suitable for preliminary staging of lung adenocarcinoma and squamous cell carcinoma than 18F-FDG, while the opposite is true in small cell lung cancer and high-grade neuroendocrine tumors.

Objective To analyze current situation and development tendency of medical teaching case library construction and to provide information for medical teaching reform. Methods Bibliometrics was used to retrieve and analyze literatures on the subject of medical teaching case library construction from China National Knowledge Infrastructure, CBMdisc, VIP and Wanfang Data from construction to June 20th,2017. Results Totally 116 articles published in 71 journals were included.A gradual growth was found in the number of publication and funded articles. The average citation count was 2.05. A majority of articles were produced in Beijing, Guangdong and Shanghai. Medical teaching case library covered 9 majors and 42 courses and applied in class teaching (50.00%, 58/116), clinical practice (37.07%, 43/116), refresher training (2.59%, 3/116), assessment and evaluation (0.86%, 1/116). Satisfaction investigate,examination score analysis and expert review were commonly used to evaluate the quality of case library. Conclusions Researches in China on medical teaching case library construction were increasing in recent years.Case library were applied in various aspects of medical teaching,however, there still remained some problems.Articles on the subject of case library were not highly-cited.There was no core author group yet. The subject on medical case library still needed deep and further exploration. There′s suggestion that we should attach importance to medical case library construction and related study to push medical education reform.
