Self-injury behavior (SIB) is a common problem behavior of children with autism spectrum disorder (ASD), which is characterized by a series of harmful reactions made by themselves causing tissue and physical damages.It seriously affects the physical and mental health in children.An early identification of SIB in children with ASD is helpful to relieve symptoms and improve the prognosis.Aiming to enrich the understanding of SIB in children with ASD and to promote early detection and intervention, this article reviews and summarizes the research on clinical characteristics, influencing factors, evaluation, detection and intervention methods of SIB in children with ASD in recent years.

Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by difficulties in social communication and interaction, restricted and repetitive behaviors, interests and activities, and abnormal perception.Obsessive compulsive disorder (OCD) is one of the common comorbid mental diseases of ASD.Accurate identification of the obsessive-compulsive symptoms and OCD comorbidity of ASD and early intervention are essential for the prognosis of patients.However, there are few domestic studies on comorbid OCD in ASD.Based on previous studies abroad, the progress of research on the epidemiology, etiology and neural mechanism, clinical characteristics, evaluation, diagnosis, intervention and treatment of comorbid OCD in ASD was reviewed in this paper.It aims to identify the manifestations of OCD in ASD patients in the early stage and improve the prognosis of patients.

Objective:To study the effects of rolling blood pump parameters and blood concentration on hemolysis during extracorporeal circulation.Methods:According to the extracorporeal hemolysis experiment standard, an extracorporeal circulation experimental device was built to analyze the influences of circulation time (0 ~ 90 min), blood flow rate (1~4 L/min), and blood volume fraction (60%, 70%) on the hemolysis of blood samples in the circulatory system. The results of hemolysis were analyzed using first-order linear regression.Results:The longer the blood pump circulation time, the greater the hemolysis rate; the higher the blood flow rate, the greater the hemolysis rate. When the flow rate is 1 and 2 L/min, the hemolysis rate curve has an inflection point that changes with time, i.e. when the circulation time exceeds 30 min, the slope of the hemolysis rate curve suddenly increases. However, when the flow rate is 3 and 4 L/min, the hemolysis mutation phenomenon is not obvious. Compared to the blood sample with blood volume fraction of 70%, a blood sample with a blood volume fraction of 60% is less prone to hemolysis.Conclusions:The longer the blood pump circulation time and the higher the blood flow rate, the more easily the red blood cells are destroyed, i.e. the hemolysis rate is directly proportional to the circulation time and blood flow rate. When the circulation time increases to a certain degree, an inflection point appears in the hemolysis rate curve, and the hemolysis trend will be significantly enhanced.

OBJECTIVETo compare the validity of three currently used chronic myeloid leukemia (CML) scoring systems (Sokal CML prognostic scoring system, Hasford prognostic scoring system, and EUTOS prognostic scoring system) in chronic phase CML (CP-CML) patients.
METHODSOne hundred and thirteen CP-CML patients taking hydroxyurea, interferon or imatinib were enrolled in this study. All patients were stratified into different groups according to each scoring system and different therapies respectively. And overall survival (OS) rates were observed and compared among different groups.
RESULTSThree scoring systems were effective predictors of OS in CP-CML patients, and EUTOS scoring system may predict more validly. Hasford scoring system was well correlated with Sokal and EUTOS scores (r=0.792, P<0.01 and r=0.624, Plt;0.01). The correlation between Sokal and EUTOS scores was relatively weak (r=0.508, Plt;0.01). Despite imatinib's marked effect in prolonging survival of CML patients, it was incapable of prolonging survival in Sokal, Hasford and EUTOS high- risk patients.
CONCLUSIONEUTOS prognostic scoring system may predict better than Sokal and Hasford systems in CML patients. Classification of patients based on the three scoring systems may assist in the choice of appropriate therapy for CML.

Objective:
To investigate the levels of cytidine/uridine monophosphate kinase 2(CMPK2) expression in CD4+T cells of systemic lupus erythematosus(SLE) patients and its correlation with clinical indicators. Additionally, to explore whether CMPK2 can induce pyroptosis in CD4+T cells of SLE patients through NLRP3, potentially providing a new target for the diagnosis and treatment of SLE.
Methods:
RT-qPCR and Western blot analyses were used to assess the gene and protein expression levels of CMPK2 in SLE CD4+T cells and healthy controls(HC). Pearson or Spearman correlation analysis was performed to evaluate the relationship between CMPK2 mRNA expression levels and clinical indicators. Subsequently, the expression levels of pyroptosis-related proteins, including NLRP3, apoptosis-associated speck-like protein containing a CARD(ASC), caspase-1, gasdermin D(GSDMD), and the N-terminal domain of GSDMD(GSDMD-N), were examined in SLE CD4+T cells and HC. Furthermore, the protein expression levels of NLRP3, ASC, caspase-1, GSDMD, and GSDMD-N were detected after silencingCMPK2in SLE CD4+T cells.
Results:
CMPK2 expression was significantly elevated in SLE CD4+T cells, exhibiting a positive correlation with SLE disease activity index(SLEDAI), anti-dsDNA antibody, anti-nucleosome antibody, anti-C1q antibody, and a negative correlation with complement C3 and C4 levels. Additionally, the expression levels of pyroptosis-related proteins, including NLRP3, ASC, caspase-1, GSDMD, and GSDMD-N significantly increased in SLE CD4+T cells(P<0.05), Moreover, the levels of cytokines IL-1β and IL-18 in the cell culture supernatants were elevated, and there was a notable increase in the rate of cellular pyroptosis(P<0.05). Silencing CMPK2 led to a reduction in the levels of these markers(P<0.05).
Conclusion
CMPK2 is highly expressed in SLE CD4+T cells and may serve as a diagnostic marker for SLE. Moreover, it is likely involved in the pathogenesis of SLE by promoting CD4+T cell pyroptosis through NLRP3.
