Objective: On the basis of the dominant frequency index of functional connectivity, the "brain age" analysis method was used to explore abnormal development patterns of sensorimotor networks in boys with autism spectrum disorder(ASD). Methods: The resting state functional magnetic resonance data (7-12 years old) for 105 boys with ASD and 102 matched boys with normal development from the ABIDE public database were screened. Functional connection networks in different frequency bands of sensorimotor related brain regions were constructed for each individual, and the frequency of the strongest connection were constructed as the optimal frequency of the connection. Brain age analysis was used to explore the difference between brain age and chronological age in boys with ASD. Results: The brain sensorimotor network of boys with ASD showed an abnormal development pattern of overdevelopment followed by underdevelopment, and the transition between the two patterns occurred at approximately 7.8 years of age. Older boys with ASD (older than 10 years) whose underdevelopment trend was suppressed had lower ASD severity( r=-0.43, P < 0.05 ). Conclusion The brain sensorimotor network in boys with ASD has an abnormal development process, and the brain chronological age difference in the sensorimotor network has potential as a neuroimaging marker to measure the development of ASD.

Objective:To investigate the clinical value of peripheral blood circulating tumor cells (CTC) in the diagnosis and treatment of prostate cancer.Methods:Sixty-four patients with prostate cancer who received treatment in Xinjiang Production and Construction Corps Hospital, China between June 2018 and May 2020 were included in the cancer group. An additional 35 patients with benign prostatic lesions who concurrently received treatment in the same hospital were included in the benign disease group. Twenty male patients with non-prostate disease were included in the control group. Cell enrichment, separation, staining and identification together with Gleason score and pathological stage were subjected to one-way analysis of variance.Results:The percentage of patients with CTC count ≥ 3 in the cancer, benign disease and control groups was 73.43% (47/64), 17.14% (6/35) and 10.00% (2/20), respectively. The level of prostate-specific antigen in patients with CTC was significantly higher than that in patients without CTC ( t = 2.89, P < 0.05). There was significant difference in CTC count between different Gleason score groups ( F = 3.25, P < 0.05) and between different pathological stage groups ( F = 3.42, P < 0.05). Conclusion:Peripheral blood CTC measurement can be used as an auxiliary method for the differentiation of benign and malignant prostate diseases. CTC count in patients with prostate cancer is correlated with prostate-specific antigen level, Gleason score, and pathological stage. Therefore, peripheral blood CTC measurement plays an auxiliary role in predicting prognosis in patients with CTC. This study is innovative and scientific.

Objective:To fabricate an all-ceramic crown which copies the morphology of preoperative tooth in one patient with only small occlusal dentin defects with completely digital design (CDD)technology,and to find a more precise and feasible solution to fix the tooth detect.Methods:The tooth treated with root canal therapy had the complete axial surface and small occlusal dentin defects.In order to keep the morphology of preoperative tooth,the digitized crown was designed with the information of preoperative tooth by oral scanning with CS3500 and using the"Biogeneric Copy"function of exocad design software,then the digitized information of the teeth was collected and transformed and the simulate zirconia crown was mode by 3D colloidal deposition technique.The patient's comfort and satisfaction were investigated by observing the morphology,the interproximal contacts,and the occlusion of crown.Results:The morphology of definitive restoration was similar to the preoperative tooth,which presented good interproximal contact and occlusion,and the patient was greatly satisfied without discomfort and foreign body sensation.Conclusion: A more accurate and personalized restoration approach can be implemented with the application of CDD to fabricate new ceramic crowns which copy the preoperative tooth.

Objective: To analyze the situation of AIDS knowledge and discrimination among freshmen in Chengdu city, and to explore possible effects of AIDS knowledge on discrimination. Methods: A cluster random sampling was employed to investigate 1 053 college students from 11 universities in Chengdu about their HIV/AIDS knowledge and discrimination. The scores of AIDS knowledge and discrimination of students with different characteristics were analyzed, and the influence path of AIDS knowledge on AIDS discrimination were further analyzed based on different peer relationships. Results: The total scores of AIDS knowledge was negatively correlated to AIDS discrimination( r s =-0.13, P <0.01). After adjusting for confounding factors, the total score of AIDS knowledge was associated with the total score of AIDS discrimination( β =-0.12, P <0.01). AIDS knowledge played a role in AIDS discrimination in intimate, general and unfamiliar peer relationships, with standardized path coefficients of -0.20, -0.24 and -0.18 respectively( P <0.01). Conclusion AIDS knowledge are correlated with discrimination among freshmen under different peer relationships. More anti-AIDS discrimination courses should be added to AIDS education to reduce the students’ fear and stigma of HIV/AIDS patients and related risk groups.

Objective:To construct single-cell transcription landscape of T cell in peripheral blood mononuclear cells(PBMCs) and thyroid tissue of patients with Hashimoto ′s thyroiditis(HT), and to analyze the changes in the proportion and functionality of T cell clusters in HT disease state.Methods:Single cell RNA sequencing was performed on PBMCs and thyroid tissue from 5 HT patients. Single cell RNA sequencing data of PBMCs from 5 healthy individuals were retrieved from public databases. After preliminary clustering, the clusters expressing CD3E were extracted and clustering again, and the names of each cluster were determined according to the known cell markers. The proportion of each cell subtype was compared, and the differentially expressed genes in different samples were analyzed.Results:After quality control, the 71 533 T cells were classified into 19 cell clusters. Among them, the proportion and function of C1_CD4 + Naive T cell clusters, C3_CD4 + Treg cell clusters, C7_CD8 + Naive T cell clusters, C8_GNLY -CD8 + T cell clusters, C10_RORC + CD8 + T cell clusters, C11_ GZMK + CD8 + T cell clusters, C12_CCL4 + CD8 + T cell clusters, and C18_PTGDS + NK cell clusters in thyroid tissue of HT patients were significantly different from those in PBMCs of healthy controls and HT patients. Conclusion:The proportion of multiple T cells in thyroid tissue of HT patients were significantly different from those in PBMCs. Among them, the proportion of three of CD8 + T cell subsets with high expression of cell killing-related genes in thyroid tissue T cells of HT patients is higher than that in PBMCs T cells, and it is statistically significant. In addition, the functionality of various T cells in the thyroid tissue of HT patients are also significantly different from those in PBMCs. A cluster of GZMK + CD8 + T cells showes significantly lower expression of genes related to PD1 pathway in thyroid tissues of HT patients compared with cells in PBMCs of HT patients, also a cluster of CCL4 + CD8 + T cells showes significantly lower expression of genes related to IL-12 pathway.

[Objective] To explore the effects of dyslipidemia and obesity on high-risk prostate cancer, so as to provide reference for the prevention and treatment of prostate cancer. [Methods] The clinical data of 175 patients with prostate cancer admitted to our hospital during Jun.2016 and Jun.2022 were retrospectively analyzed, including 122 high-risk prostate cancer and 53 non-high-risk prostate cancer.The logistic regression analysis were conducted to identify independent risk factors affecting the occurrence of high-risk prostate cancer.Evaluate the predictive value and optimal cutoff value of risk factors such as age, cholesterol, body mass index (BMI), and prostate-specific antigen (PSA) for the occurrence of high-risk prostate cancer through receiver operating characteristic (ROC) curves.Spearman analysis was used to investigate the correlation between Gleason scores and different risk factors. [Results] The age, BMI, cholesterol, PSA, incidence of obesity (BIM≥25) and high cholesterol in the high-risk prostate cancer group were all higher than those in the non-high-risk prostate cancer group (P<0.05). Multivariate logistic regression showed that age (OR=1.097, 95%CI: 1.005-1.198, P=0.039), obesity (OR=4.459, 95%CI: 1.305-15.239, P=0.017), PSA (OR=1.170, 95%CI: 1.069-1.280, P=0.001), and cholesterol (OR=5.544, 95%CI: 1.304-23.577, P=0.020) were risk factors for high-risk prostate cancer.The ROC curve showed that the optimal cutoff values for age, cholesterol, BMI, and PSA were 74.50 years (AUC: 0.748, 95%CI: 0.678-0.818), 3.70 mmol/L (AUC: 0.800, 95%CI: 0.731-0.870), 24.97 (AUC: 0.621, 95%CI: 0.532-0.711), and 18.67 ng/mL (AUC: 0.864, 95%CI: 0.813-0.916), respectively, and the combined prediction value of age, cholesterol, BMI, and PSA for high-risk prostate cancer was the highest (AUC: 0.931, 95%CI: 0.895-0.967). The age (r=0.464, P<0.001), BMI (r=0.222, P=0.003), cholesterol (r=0.501, P<0.001), and PSA (r=0.473, P<0.001) were positively correlated with Gleason by Spearman analysis. [Conclusion] Obesity, age, PSA, and cholesterol level are independent risk factors for high-risk prostate cancer.When the age is ≥74.50 years, cholesterol level is ≥3.70 mmol/L, BMI is ≥24.97, PSA level is ≥18.67 ng/mL, the possibility of developing high-risk prostate cancer is high.

【Objective】 To observe the efficacy of abiraterone (AA) in the treatment of metastatic castration-resistant prostate cancer (mCRPC). 【Methods】 The clinical data of a newly diagnosed metastatic hormone sensitive prostate cancer (mHSPC) patient with high risk and high tumor load were analyzed. After operation and endocrine therapy, the disease evolution was observed. Relevant literature was reviewed. 【Results】 After laparoscopic radical prostatectomy, 6-month bicalutamide and androgen deprivation therapy (ADT), the total prostate specific antigen (tPSA) was reduced to the lowest of 0.51 ng/mL, and then increased month by month. After domestic abiraterone (trade name: Qingkeshu) in the 8th month was administered for 4 months, tPSA continued to increase to 12.39 ng/mL. The case was then diagnosed as mCRPC. The treatment was adjusted again in the 11th mouth and the patient received AA (trade name: Zeke) combined with prednisone and ADT, and tPSA decreased to 0.17 ng/mL 2 months later. After 14 months of treatment, tPSA remained at about 0.12 ng/mL. Systemic ECT examination indicated that the range of bone metastases decreased and some areas of nuclide concentration turned shallow without obvious adverse reactions. 【Conclusion】 AA combined with prednisone and ADT can produce rapid decline in PSA and a good response in mCRPC patients. It can also significantly slow the progression of bone metastasis and relieve pain symptoms without obvious adverse reactions. Long-term efficacy needs further observation.

Objective    To systematically review the impact of chronic kidney disease (CKD) at different stages on prognosis of transcatheter aortic valve replacement (TAVR). Methods    Databases including PubMed, the Cochrane Library, EMbase, Web of Science, CNKI, Wanfang and the Chinese Biomedical Literature Database (CBM) were searched by computer to collect cohort studies on impact of different stages of CKD on prognosis of TAVR from inception to July 2020. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies, and then, meta-analysis was performed by using Stata 15.0 software. Risk of study bias was assessed using the Newcastle-Ottawa Scale (NOS). Results    A total of 17 cohort studies were included with NOS score≥6 points. The results of meta-analysis indicated that: compared with the patients without CKD, all-cause mortality of CKD stage 3 patients at 30 day (RR=1.29, 95%CI 1.22-1.37, P<0.001) and 1 year (RR=1.24, 95%CI 1.19-1.28, P<0.001), all-cause mortality of CKD stage 4 patients at 30 day (RR=2.10, 95%CI 1.90-2.31, P<0.001) and 1 year (RR=1.89, 95%CI 1.62-2.19, P<0.001), and all-cause mortality of CKD stage 5 patients at 30 day (RR=2.22, 95%CI 1.62-2.19, P<0.001) and 1 year (RR=2.24, 95%CI 1.75-2.87, P<0.001) were significantly increased and were associated with the severity of CKD. The occurrence rates of 1-year cardiovascular mortality, postoperative acute kidney injury and bleeding events were all higher in patients with CKD. Conclusion    CKD at stages 3, 4 and 5 is associated with increased all-cause mortality after TAVR, and the higher the stage of CKD is, the higher the risk of all-cause mortality at 30-day and 1-year follow-up is. Due to limited quality and quantity of the included studies, more high-quality studies are required to verify above conclusions.
