Alzheimer's disease (AD) is the major form of dementia in the elderly and is closely related to the toxic effects of microglia sustained activation. In AD, sustained microglial activation triggers impaired synaptic pruning, neuroinflammation, neurotoxicity, and cognitive deficits. Accumulating evidence has demonstrated that aberrant expression of deubiquitinating enzymes is associated with regulating microglia function. Here, we use RNA sequencing to identify a deubiquitinase YOD1 as a regulator of microglial function and AD pathology. Further study showed that YOD1 knockout significantly improved the migration, phagocytosis, and inflammatory response of microglia, thereby improving the cognitive impairment of AD model mice. Through LC-MS/MS analysis combined with Co-IP, we found that Myosin heavy chain 9 (MYH9), a key regulator maintaining microglia homeostasis, is an interacting protein of YOD1. Mechanistically, YOD1 binds to MYH9 and maintains its stability by removing the K48 ubiquitin chain from MYH9, thereby mediating the microglia polarization signaling pathway to mediate microglia homeostasis. Taken together, our study reveals a specific role of microglial YOD1 in mediating microglia homeostasis and AD pathology, which provides a potential strategy for targeting microglia to treat AD.

Objective To observe the value of prenatal ultrasound graded management of Sylvian fissure for diagnosing fetal lissencephaly.Methods Totally 39 fetuses with MRI diagnosed lissencephaly who underwent prenatal ultrasound examination were retrospectively enrolled and divided into non-graded management group(n=20)and graded management group(n=19)according to prenatal ultrasound examination before or after the application of prenatal ultrasound graded management of Sylvian fissure(i.e.prenatal ultrasound routine screening for fetal Sylvian fissure morphology).The diagnosis of prenatal ultrasound were compared and analyzed between groups,and the diagnostic value of graded management was evaluated.Results Among 20 fetuses in non-graded management group,prenatal ultrasound showed lissencephaly in 4 fetuses,but only other structural abnormalities in 16 fetuses.Then the latter were re-evaluated based on prenatal ultrasound graded management of Sylvian fissure,among which 4 fetuses could not be evaluated since not standard ultrasonic section,2 fetuses with severe hydrocephalus and Sylvian fissure could not be seen,while Sylvian fissure morphology did not match the corresponding gestational week in 4 fetuses,and type Ⅰ(no platform type)and type Ⅴ(Z-shaped)were noticed in 5 and 1 fetus,respectively.In graded management group,prenatal ultrasound indicated 15 fetuses with lissencephaly,including Sylvian fissure morphology did not match the corresponding gestational week in 6 fetuses,type Ⅰ(no platform type),type Ⅲ(linear type)and type Ⅴ(Z-shaped)were detected in 7,1 and 1 fetus,respectively,while no clear diagnosis was obtained in 4 fetuses.Prenatal ultrasound detection rate of fetal lissencephaly in graded management group(15/19,78.95％)was significantly higher than that in non-graded management group(4/20,20.00％)(P＜0.01).Conclusion Based on graded management of Sylvian fissure could improve the efficiency of prenatal ultrasound for diagnosing fetal lissencephaly.

BackgroundSchool bullying is a serious social issue. Non-suicidal self-injury （NSSI） is a highly prevalent behavior among adolescents with depression and is also becoming a great matter of concern. Previous studies have proved a very close correlation among school bullying， experiential avoidance， family functioning， and NSSI behavior. However， there is a considerable lack of research on the moderating role of family functioning in the relationship between school bullying and experiential avoidance in adolescents with depression in China. ObjectiveTo explore the mediating role of experiential avoidance in the relationship between school bullying and NSSI in adolescents with depressive disorder， and the moderating role of family functioning in the relationship between school bullying and experiential avoidance， so as to provide references for formulating intervention strategies for NSSI in adolescents with depressive disorder. MethodsFrom January to December 2024， 318 consecutive adolescent patients fulfilling the Diagnostic and Statistical Manual of Mental Disorders， fifth edition （DSM-5） diagnostic criteria for depression and attending the outpatient department of Weifang Mental Health Center were selected. All respondents completed the Delaware Bullying Victimization Scale-Student （DBVS-S）， Acceptance and Action Questionnaire-II （AAQ-II）， Family Assessment Device （FAD）， and Behavioral Questionnaire in the Adolescent Non-suicidal Self-injury Assessment Questionnaire （ANSAQ）. Pearson correlation was used to examine the relationship among variables. SPSS Process Macro v4.1 package program was utilized to seek the mediating and moderating effects. ResultsData were collected from 306 valid respondents （96.23%）. In adolescent with depressive disorder， DBVS-S score was positively correlated with both the behavioral questionnaire score in the ANSAQ and the AAQ-II score （r=0.357， 0.558， P<0.01）. AAQ-II score was positively correlated with the behavioral questionnaire score in the ANSAQ （r=0.380， P<0.01）. Experiential avoidance partially mediated the relationship between school bullying and NSSI in adolescents with depressive disorder， and the mediating effect value was 0.142 （95% CI： 0.081~0.204）. Family functioning moderated the relationship between school bullying and experiential avoidance， and the moderated mediation value was 0.096 （95% CI： 0.042~0.165）. ConclusionMediation is found from school bullying to NSSI behavior through experiential avoidance in adolescents with depressive disorder， and family functioning plays a moderating role in the relationship between school bullying and experiential avoidance.

Yi Dagen was a famous physician of Xujiang School in Ming Dynasty.In the process of syndrome differentiation and treatment,Yi Dagen attached great importance to pulse diagnosis and paid attention to the influence of time factors.His theory was based on"Yin and Yang having time rules and coordinating with pulse"in Basic Questions:The subtlety of pulse diagnosis,emphasizing the mutual reference of pulse and time,reflecting the fundamental principle of"correspondence between nature and man"in traditional Chinese medicine.The thought of mutual reference of pulse and time is mainly reflected in two levels:one is to guide syndrome differ-entiation,which can be summarized as referring to midnight-midday ebb flow to identify the location of the disease,referring to the four-season and five-viscus pulse method to identify the cause of the disease,referring to the north-south governance to identify the nature of the disease,and choosing the time to diagnose the pulse to identify the disease situation;the second is the whole process of syndrome differentiation and treatment,including pulse and time diagnosis and treatment according to the time.The idea of mutual ref-erence of pulse and time plays an important guiding role in current clinical work.In the future,wearable pulse diagnosis equipment and intelligent monitoring technology can be combined to build a dynamic pulse analysis system to realize the real-time and precise applica-tion of the"mutual reference of pulse and time"theory.

Cerebral autoregulation (CA), as one of the intrinsic mechanisms for maintaining cerebral hemodynamic homeostasis, utilizes various regulatory methods to induce vasoconstriction reactions in resistance vessels, mainly small blood vessels, to maintain relatively constant cerebral blood flow perfusion within a certain range of blood pressure fluctuations. It has important value in evaluating the severity and predicting the outcome of acute ischemic stroke. This article reviews the evaluation methods of CA and its application in patients with acute ischemic stroke.

Objective To observe the efficacy of low grip strength and grip asymmetry in predicting multiple postoperative outcomes in elderly patients with colorectal cancer. Methods A total of 257 elderly colorectal cancer patients were selected as study objects. Data on general information, grip strength indicators and adverse postoperative outcomes were collected from all patients. Associations of low grip strength, grip asymmetry with adverse postoperative outcomes were explored by Logistic regression.
