Metanephric adenoma is a rare renal epithelial tumor with a low incidence and lack of specific clinical manifestations，resulting in a lack of uniformity in clinical understanding and treatment. Its etiology and pathogenesis are still unclear，and it may be related to the abnormal number and structure of chromosomes 2，7，and 17，as well as mutations in genes such as BRAF V600E，NF1，and NOTCH1，etc. There may be a transformed relationship between this tumor and Wilms’ tumor and papillary renal cell carcinoma. For diagnosis，it has diverse but non-specific clinical manifestations，and it is difficult to accurately differentiate it from other tumors in the imaging examination，and the confirmation of diagnosis relies on pathological and immunohistochemical staining. Treatment is mainly based on surgery to preserve the renal unit，such as partial nephrectomy，etc.，but the difficulty of preoperative diagnosis often leads to over-treatment，and there is a lack of standardized treatment protocols for metastatic posterior renal adenoma. The aim of this article is to provide a reference for the in-depth understanding of posterior renal adenomas and to optimize the clinical diagnosis and treatment strategies.

[Objective]To investigate the prevalence rate of chronic non-communicable diseases(NCDs)and the association with quality of life in middle-aged and elderly patients with HIV/AIDS.[Methods]This cross-sectional study surveyed 432 patients with HIV/AIDS(aged≥45 years)in the Infectious Disease Center in Guangzhou Eighth People's Hospital of Guangzhou Medical University,and 366 participants were included in the analysis after quality control.A questionnaire and the EuroQol 5-Dimensional 3-level version(EQ-5D-3L)were used to investigate NCDs and quality of life and Tobit regression model was used to estimate the association between chronic diseases and quality of life.[Results]Among the 366 participants,29(7.9%)had cardiovascular disease,45(12.3%)had hypertension,122(33.3%)had hyperglycemia,151(41.3%)had hyperlipidemia,7(1.9%)had cancer,17(4.6%)had chronic kidney disease,38(10.4%)had chronic liver disease,21(5.7%)had musculoskeletal disorders,and 253(69.1%)suffered from at least one type of chronic diseases.The median(lower and upper quartiles)of EQ-5D utility index was 1.000(0.964～1.000).Multivariate Tobit regression results of the total population showed that cancer[ba=-0.08,95%CI(-0.15,-0.01),P=0.036],chronic kidney disease[ba=-0.07,95%CI(-0.12,-0.02),P=0.006],musculoskeletal disease[ba=-0.09,95%CI(-0.13,-0.05),P<0.001],and≥3 types of chronic diseases[ba=-0.05,95%CI(-0.08,-0.01),P=0.013]were negatively correlated with EQ-5D utility index.The stratified analysis results of different CD4+T cell levels showed that hypertension[ba=-0.07,95%CI(-0.12,-0.02),P=0.007],chronic kidney disease[ba=-0.10,95%CI(-0.18,-0.03),P=0.006],musculoskeletal disease[ba=-0.15,95%CI(-0.22,-0.07),P<0.001]and≥3 types of chronic diseases[ba=-0.09,95%CI(-0.09,-0.01),P<0.001]were negatively correlated with EQ-5D utility index in the group with CD4≤500(cells/μL),whereas cancer[ba=-0.11,95%CI(-0.20,-0.01),P=0.031]was negatively correlated with EQ-5D utility index in the group with CD4＞500(cells/μL).[Conclusions]The prevalence rate of chronic non-communicable diseases in middle-aged and elderly patients with HIV/AIDS is relatively high.The classification of NCDs such as cancer or chronic kidney disease or other chronic diseases and the numbers of NCDs categories are negatively correlated with quality of life.However,this association varies among patients with HIV/AIDS of different CD4+T cell levels.It is suggested that we should try to prevent and identify NCDs at an early stage,strengthen linkages and integration of health services for AIDS and chronic NCDs,and jointly manage and control AIDS with chronic diseases to improve the quality of life among people living with HIV/AIDS.

YTHDF2 is a key m6A RNA modification"reader"that plays a crucial role in cell biological processes and tumor development.This review deeply explores the biological role of YTHDF2 and the advances in its application in tumors.The YTHDF2 structures are divided into mRNA procsomes and YTH domains,which recognize and bind m6A modified RNA molecules.It plays a biological role by promoting mRNA degradation,regu-lating cell signaling pathways and metabolism,and can regulate macrophage function and maintain an immunosup-pressive state in the tumor microenvironment.YTHDF2 has the potential to serve as diagnostic markers,therapeu-tic targets and prognostic evaluation biomarkers in different tumors,but currently relevant studies are insufficient in sample size,molecular mechanism and clinical application.In the future,research can be conducted on compre-hensive clinical research,in-depth analysis of molecular mechanisms,and research and development of optimized treatment strategies.

Male primary adenocarcinoma of urethra is rare clinically. A patient with primary adenocarcinoma of posterior urethra complicated with intestinal metaplasia was admitted and underwent urethral mass resection. The tumor recurred 3 months after surgery and no further treatment was given for personal reasons. The purpose of this report is to improve clinicians' understanding of urethral cancer, so that patients can undergo more accurate diagnosis and treatment.

Objective To investigate the characteristics of spatial orientation language comprehension and expression behavior ofchildren with autism. MethodsA three-ladder test was designed to test the comprehension and expression of "(go/come) to" sentences, including general subject-predicate sentences, conjunctive-predicate sentences with displacement purposes, and conjunctive-predicate sentences with displacement modes. March to June, 2022, the test was conducted on 17 children with autism from a special education school and 17 healthy children matched the scores of Peabody Picture Vocabulary Test-Chinese revised from a kindergarten. The typical errors were analyzed for children with autism. ResultsThe main effects of sentence ladders (F > 3.718, P < 0.05) and children groups (F > 8.782, P < 0.001) were significant on comprehension and expression of sentences, while the performance was poor for the complex sentences and for the children with autism. The common types of errors in expression were missing components, mixed sentences, autonomous sentences, inaccurate wording, inconsistent content, blending errors and non-response. The numbers and the distribution of error types were quite different from the children with autism to the healthy children. ConclusionChildren with autism are more difficult to understand and express "(go/come) to" sentences, mainly manifested in a higher error frequency and more kinds of error.

The Brodmann area(BA)-based map is one of the most widely used cortical maps for studies of human brain functions and in clinical practice;however,the molecular architecture of BAs remains unknown.The present study provided a global multiregional proteomic map of the human cerebral cortex by analyzing 29 BAs.These 29 BAs were grouped into 6 clusters based on similarities in proteomic patterns:the motor and sensory cluster,vision cluster,auditory and Broca's area cluster,Wernicke's area cluster,cingulate cortex cluster,and heterogeneous function cluster.We identified 474 cluster-specific and 134 BA-specific signature proteins whose functions are closely associated with specialized functions and disease vulnerability of the corresponding clus-ter or BA.The findings of the present study could provide explanations for the functional connec-tions between the anterior cingulate cortex and sensorimotor cortex and for anxiety-related function in the sensorimotor cortex.The brain transcriptome and proteome comparison indicates that they both could reflect the function of cerebral cortex,but show different characteristics.These pro-teomic data are publicly available at the Human Brain Proteome Atlas(www.brain-omics.com).Our results may enhance our understanding of the molecular basis of brain functions and provide an important resource to support human brain research.

Multiple myeloma is a plasma cell disease with the second highest incidence among hematological malignancies. Its risk of concurrent thrombosis is high, which greatly affects the quality of life and even endangers life of multiple myeloma patients. The pathogenesis of thrombosis in patients with multiple myeloma is complex, which is still unclear. However many mechanisms are considered to be related to hypercoagulable state in patients with multiple myeloma. Currently, there is a lack of thrombosis risk assessment model for multiple myeloma. Therefore, this paper reviews the research and the latest progress of venous thrombosis in patients with multiple myeloma, and provides a theoretical basis for the prevention and treatment of thrombosis.
