Objective To explore the expressions and significances of apoptotic modulating genes Fas and Bcl-2 mRNA in peripheral blood monocytes(PBMC)of patients with myasthenia gravis (MG). Methods The levels of Fas and Bcl-2 mRNA in PBMC were detected by semi-quantitative reverse transcription-polymerase chain reaction (RT-PCR) in 44 patients with MG as well as 30 healthy donors served as a normal control (NC).Results (1) The level of Fas mRNA in MG group was no significantly difference compared with NC group. The level of Bcl-2 mRNA in MG group was higher than that in NC group(P

Objective To investigate the frequency of c-kit mutation and prognosis in t (8;21) acute myeloid leukemia (AML) patients with trisomy 4. Methods A total of 145 de novo t(8;21) AML patients from February 2005 to January 2013 were analyzed retrospectively. Detection of exons 8 and 17 mutation of c-kit by PCR and cytogenetic analysis by R-banding technologies were performed on bone marrow samples of all patients at diagnosis. Clinical data were collected and analyzed statistically. Results Among 145 t (8;21) AML patients, 12 cases (8.3 %) were trisomy 4, 91.7 % (11/12) of them were identified with c-kit mutation, which was significantly higher than that without trisomy 4 [26.3 % (35/133), P< 0.01]. The follow-up data showed that the patients with trisomy 4 were correlated with the lower overall survival (OS) rate (15 % vs 56 %, P< 0.01) and disease-free survival (DFS) rate (0 vs 51 %, P< 0.01) when compared with patients without trisomy 4. Furthermore, the subgroup of patients with both trisomy 4 and c-kit mutation had a worse OS and DFS (P< 0.05). Conclusions Trisomy 4 is associated with high frequency of c-kit mutation and demonstrates poor prognosis in t(8;21) AML patients. Trisomy 4 or it combined with c-kit gene mutation is the main influencing factor on the survival of the patients with t(8;21) AML.

Infantile neuroaxonal dystrophy (INAD) is a rare autosome-recessive disease characterized by progressive motor and cognitive regression.The PLA2G6 gene is its causative gene,which encodes calcium-independent phospholipase A2 enzyme (iPLA2-VIA).The diagnosis of INAD is difficult because of its clinical heterogeneity,and the rate of misdiagnosis is high.The purpose of this study is to describe the clinical characteristics,molecular genetics,treatment and prognosis of INAD to improve the acknowledgement of INAD in medical workers and to help make an early diagnosis of INAD.

Objective To explore the clinical features,genetic causes and prognosis of intellectual disability with epilepsy(ID-E)in children.Methods The data of unknown causes of ID-E children(n=40)who were identified in Department of Pediatrics,Xiangya Hospital of Central South University from March 2015 to March 2016 were respectively analyzed,and follow-up studies were performed to investigate the epilepsy control and intellectual deve-lopment.Results Forty unexplained ID-E included 25(62.5%)male,and 34(85.0%)cases were severe intellectual disability patients.The onset age of epilepsy was 0.16 to 8.00 years old,median age was 1.5 years old.Twenty cases(50.0%)had slow electroencephalogram background,and 22 cases(55.0%)had focal spikes.Ten cases(25.0%)had abnormal cranial images,with brain dysplasia or atrophy.Follow-up lasted from 0.58 to 1.58 years,and 19 cases(47.5%)had seizure control.Twenty-five cases(62.5%)had used at least 2 anti-epilepsy drugs during follow-up,and 19 cases(47.5%)had drug refractory epilepsy.Improvement of mental or motor development in epilepsy controlled group and the uncontrolled group were 12 cases(63.2%)and 2 cases(9.5%).There were separately 8 cases(8/40 cases,20.0%)and 3 cases(3/16 cases,18.8%)diagnosed respectively by whole genome-wide analysis of copy number variants(CNVs)and gene-panel whose CNVs test findings were negative.Conclusions ID-E patients of unknown causes have the following clinical features:they were mostly found in male patients with severe intellectual disability,and drug refractory epilepsy patients have rather high percentage;well controlling of epilepsy is useful for improvement of mental and motor development.Genetic analysis is significant for control and prognosis of ID-E patients,and genome-wide CNVs have high positive rates which can be used as first-tier test to detect genetic etiology of ID-E of unknown cause.

Objective:
Hundreds of countries have implemented lockdown policies to slow the spread of coronavirus disease-2019 (COVID-19), but the impact of these measures on maternal mental health is not well understood.
Methods:
This study integrated a stress-process model to examine the pathways from lockdown-related stressors to prenatal psychological outcomes, with COVID-19 coping strategies (COP) and self-efficacy in managing negative affect (NEG) as mediators and lockdown duration, hours on pandemic-related information, and number of pregnancies as moderators. Pregnant women in Shanghai completed the Regulatory Emotional Self-Efficacy Scale, COVID-19 Coping Scale, Depression, Anxiety, and Stress Scale-21. Structural equation modeling (SEM) was used to test and modify the hypothetical model, and moderated mediation and slope analyses were undertaken.
Results:
In the final SEM demonstrating satisfactory fit, three stressors—decreased household income, insufficient daily supplies, and acquired infections—showed positive direct relationships with NEG and COP. Acquired infections, NEG, and COP were identified as direct predictors of mental health outcomes. The relationship between these three stressors and mental health was mediated by NEG and COP. Additionally, the number of pregnancies moderated the mediating effect of COP; this effect was more pronounced among first-time pregnant women than those with multiple pregnancies.
Conclusion
This study provides insights into how lockdown measures impact psychological outcomes in pregnant women quarantined at home. Interventions aimed at increasing coping strategies may be more effective for primiparous women during future public health emergencies.

Objective To summarize the clinical features of global developmental delay (GDD) children,and to explore the relationship between severity of GDD and social-culture factors.Methods Sign the informed consent before enrollment.Collect clinical data in detail about 100 GDD children (GDD group) and 95 children with normal development (healthy control group),and analyze their regular clinical data,physical examination,intellectual disability test,electroencephalography (EEG) and cranial imaging test.Spearman rank correlation was used to analyze the differences of social and cultural factors between GDD group and healthy control group,such as maternal reproductive age,parental education level and family economic status.At the same time,we compared the lag degree of total developmental quotient and the degree of developmental retardation of five energy areas with the above factors.Results Significant associations were found between GDD and maternal/paternal education,economic level of family,but no sgnificant association was found between maternal age and GDD.And analysis in the relationship between severity of delay in all domains of the child's developmental status about language and social-culture factors,we only obtained the severity of delay in abilities about language is related with maternal education.Spearman rank correlation statistics explains that if there are the lower level of education with mothers,the delay of language domain will more severe (rs =-0.505,P < 0.05).Conclusions Significant associations were found between GDD and maternal/paternal education,economic level of family.The higher maternal education was an important protective factor against risk of GDD.Improving the cognition of parents in child health care,early be diagnosed,early be intervened,is the most important for children with language development.
