Objective To evaluate the application value of whole exome sequencing (WES) in diagnosis of NDDs (neuro-developmental disorders) children.Metheod WES was used for the diagnosis of 35 unexplained NDD children, which admitted to the outpatient and ward of Children′s hospital affiliated to Capital institute of pediatric from November 2015 to November 2016.These children′s clinical data was collected detailedly.Using bioinformatics software tools combining with patient′s phenotype, the candidate genetic/genomic variants of these patients were identified from WES data.The final pathogenicity of genetic/genomic variants was interpreted according to the guideline of the American College of Medical Genetics and Genomics (ACMG), meanwhile, the variants validation and co-separation analysis in the parents and their family members were performed by Sanger sequencing, real time-PCR and multiplex ligation-dependent probe amplification (MLPA).Results 14 pathogenic single nucleotide variants (SNVs) and three pathogenic copy number variations (CNVs) were detected in the 35 NDD children, the detection rate in this study is 48.6%.Among the 14 pathogenic SNVs, 11 of them are the definite NDD-related genes according to OMIM database (such as CHARGE syndrome, Wiedemann-Steiner syndrome, Cockayne syndrome, etc.), and six of them are de novo (6/11, 54.6%).Three pathogenic CNVs were identified from WES data, including two microduplications and one microdeletion.Meanwhile, a female child carrying a frame shift mutation in MECP2 was found and the germline mosaicism with low-frequency mutation of this site (8.4%) was confirmed by his father's sperm.Conclusions The diagnosis rate of WES in NDDs children is 48.6% in our small-sample study.In addition to pathogenic/likely pathogenic SNVs, CNVs can be detected successfully from WES data, which effectively improved the diagnosis yield in NDDs children.

Objective: To assess the efficacy and safety of thrombolytic treatment with reteplase in patients with intermediate-risk acute pulmonary embolism. Methods: Ten consecutive patients with intermediate-risk acute pulmonary embolism who received thrombolytic treatment with reteplase at Thrombosis and Vascular Medicine Center, Fuwai Hospital from March to November in 2016 were included.Vital signs, right ventricular diameter, systolic pulmonary artery pressure, and biochemical markers were assessed before and after thrombolytic therapy with reteplase, and bleeding complications were also observed during 3 months follow up. Results: (1) For the efficacy outcomes: at 48 hours after thrombolytic treatment with reteplase, echocardiography-derived diameter of right ventricular was significant reduced from (27.9±3.8) mm to (24.8±2.6) mm (P=0.03), systolic pulmonary artery pressure decreased from (63.9±21.6) mmHg(1 mmHg=0.133 kPa) to (34.4±19.8) mmHg (P=0.02). Heart rate and breathing rate were also decreased significantly (both P<0.05), blood pressure remained unchanged post therapy.Hypoxemia was quickly corrected with an significant elevation of PaO₂ and SaO₂ ((65.2±14.3) mmHg vs. (80.0±9.6) mmHg, P=0.006; (90.8±3.5)% vs. (95.2 ±1.6)%, P=0.002 respectively). PaCO₂ was also increased significantly (P<0.05). Serum NT-proBNP and cTnI were decreased significantly (both P<0.05). There was no recurrent pulmonary embolism or deep-vein thrombosis during the 3 months follow-up. (2) For the safety outcomes: a thrombolytic relevant hemoptysis (about 70 ml) occurred in 1 patient, and was controlled by PCC therapy.No other clinically relevant events were observed during thrombolytic treatment. Eight patients were followed more than 3 months, there was no major bleeding complication or death during the follow up period. Conclusion Treatment of intermediate-risk acute pulmonary embolism with reteplase is effective and safe and there are no obvious side effects.

BACKGROUND: Little is known about the risk factors for sudden cardiac death (SCD) in the overall hospitalized cardiac department population. This study was conducted to investigate the risk factors and develop a predictive model for SCD in a hospitalized cardiac department population. METHODS: We conducted a retrospective study of patients admitted to the cardiac department of the First Affiliated Hospital of Xinjiang Medical University from June 2015 to February 2017. We collected the clinical data from medical records. Multiple stepwise logistic regression analysis was carried out to confirm the risk factors for SCD and develop a predictive risk model. The risk score was assessed by the area under receiver operating characteristic (AUROC) curve and the Hosmer-Lemeshow goodness-of-fit test. RESULTS: A total of 262 patients with SCD and 4485 controls were enrolled in our study. Logistic regression modeling identified eight significant risk factors for in-hospital SCD: age, main admitting diagnosis, diabetes, corrected QT interval, QRS duration, ventricular premature beat burden, left ventricular ejection fraction, and estimated glomerular filtration rate. A predictive risk score including these variables showed an AUROC curve of 0.774 (95% confidence interval: 0.744-0.805). The Hosmer-Lemeshow goodness-of-fit test showed the chi-square value was 2.527 (P = 0.640). The incidence of in-hospital SCD was 1.3%, 4.1%, and 18.6% for scores of 0 to 2, 3 to 5 and ≥6, respectively (P < 0.001). CONCLUSIONS Age, main admitting diagnosis, diabetes, QTc interval, QRS duration, ventricular premature beat burden, left ventricular ejection fraction, and estimated glomerular filtration rate are factors related to in-hospital SCD in a hospitalized cardiac department population. We developed a predictive risk score including these factors that could identify patients who are predisposed to in-hospital SCD.

Objective To investigate the efficacy and the collective brain responses of acupuncture for post-stroke limb numbness.Methods A total of 24 patients with post-stroke limb numbness and 23 matched healthy participants were recruited.Both groups received coordinated acupuncture treatment to regulate their physical and mental state,three times a week for 4 weeks.Changes in limb numbness assessed by the visual analog scale(VAS)were observed before and after acupuncture.Functional magnetic resonance imaging(fMRI)scans were conducted on the participants during the scanning process with acupuncture intervention.Blood oxygen level-dependent(BOLD)data were collected in three states:resting state,acupuncture task state,and needle retention state.Data processing was performed using software such as fMRIPrep and brainIAK.Intersubject correlation(ISC)analysis was conducted to compare the ISC values of different brain regions between the two groups under different conditions.Results Acupuncture treatment significantly reduced the VAS scores of limb numbness.No significant changes in ISC values in both groups during resting state.Under acupuncture conditions,the patient group exhibited significantly increased ISC values in the left precentral gyrus,left paracentral lobule,left postcentral gyrus,left insula,left anterior cingulate gyrus,right middle frontal gyruss and right anterior cingulate gyrus.Under the needle retention condition,a slight negative activation was observed in the bilateral precentral gyrus of the control group.In the patient group,the ISC values of the left superior frontal gyrus,left precentral gyrus,left paracentral lobule,left precuneus,left postcentral gyrus,left insula,left anterior cingulate gyrus,left thalamus,right superior frontal gyrus,right middle frontal gyrus,right precentral gyrus,and right anterior cingulate gyrus showed a significant increase compared to the resting state.Conclusion Acupuncture can improve post-stroke limb numbness symptoms and induce a specific pattern of collective brain activation in patients.This activation involves the precentral gyrus,postcentral gyrus,thalamus,insula,frontal lobe and cingulate gyrus.Acupuncture may enhance the processing of sensory information by activating the somatosensory-motor network and the cortical-thalamic-cortical loop.It may also modulate the central executive network and the descending pain control pathway to promote the relief of pain symptoms.

BACKGROUNDThe SYNergy between percutaneous coronary intervention with TAXus and cardiac surgery Score II (SS-II) can well predict 4-year mortality in patients with complex coronary artery disease (CAD), and guide decision-making between coronary artery bypass graft surgery and percutaneous coronary intervention (PCI). However, there is lack of data regarding the utility of the SS-II in patients with three-vessel CAD undergoing PCI treated with second-generation drug-eluting stents (DES). The purpose of the present study was to evaluate the ability of the SS-II to predict long-term mortality in patients with three-vessel CAD undergoing PCI with second-generation DES.

METHODSTotally, 573 consecutive patients with de novo three-vessel CAD who underwent PCI with second-generation DES were retrospectively studied. According to the tertiles of the SS-II, the patients were divided into three groups: The lowest SS-II tertile (SS-II ≤20), intermediate SS-II tertile (SS-II of 21-31), and the highest SS-II tertile (SS-II ≥32). The survival curves of the different groups were estimated by the Kaplan-Meier method. Univariate and multivariate Cox proportional hazard regression analyses were performed to evaluate the relationship between the SS-II and 5-year mortality. The performance of the SS-II with respect to predicting the rate of mortality was studied by calculating the area under the receiver operator characteristic (ROC) curve. The predictive ability of the SS-II for 5-year mortality was evaluated and compared with the SS alone.

RESULTSThe overall SS-II was 27.6 ± 9.0. Among patients in the lowest, intermediate and the highest SS-II tertiles, the 5-year rates of mortality were 1.6%, 3.2%, and 8.6%, respectively (P = 0.003); the cardiac mortality rates were 0.5%, 1.9%, and 5.2%, respectively (P = 0.014). By multivariable analysis, adjusting for the potential confounders, the SS-II was an independent predictor of 5-year mortality (hazard ratio: 2.45, 95% confidence interval: 1.38-4.36; P = 0.002). The SS-II demonstrated a higher predictive accuracy for 5-year mortality compared with the SS alone (the area under the ROC curve was 0.705 and 0.598, respectively).

CONCLUSIONThe SS-II is an independent predictor of 5-year mortality in patients with three-vessel CAD undergoing PCI treated with second-generation DES, and demonstrates a superior predictive ability over the SS alone.

Objective To explore the clinical value of 3D fast spin echo with an extended echo train acquistion (CUBE) T1WI enhancement sequence for purulent meningitis by comparing to contrast?enhanced T2WI?FLAIR sequence in the detection of lesions. Methods From August 2016 to July 2017, children with clinically suspected purulent meningitis underwent cranial magnetic resonance examination in our hospital. There were 35 children, 19 males and 16 females, aged 2 months to 3 years (median age 8 months) in total.A GE Discovery MR 750 3.0 T scanner was used to perform routine plain and enhanced scan in all children. After enhancement, the sequences of CUBE T1WI and FLAIR T2WI were applied randomly. Using the FLAIR T2WI enhancement sequence as the reference, we evaluated the detection rate of CUBE T1WI enhancement sequence for dura mater and leptomeningeal thickening. The number of enhanced lesions detected was tested by χ2 test. Results The enhanced FLAIR T2WI sequence showed 21 cases with dural enhancement, showing a rate of 60.0%. The enhanced CUBE T1WI sequence showed 31cases with dural enhancement, showing a rate of 88.6%. There were significant differences between the dural lesions detected(χ2＝6.058, P<0.01). The enhanced FLAIR T2WI sequence showed 16 cases of leptomeningeal enhancement,showing a rate of 45.7%. The enhanced CUBE T1WI sequence showed 19 cases of leptomeningeal enhancement,showing a rate of 54.3%.The enhanced CUBE T1WI sequence was not significantly higher than that of enhanced T2WI?FLAIR sequence in displaying leptomeningeal enhancement (χ2=0.229, P>0.05). Conclusion Enhancement of the CUBE T1WI sequence enables better visualization of meningeal thickening than FLAIR T2WI. It has great clinical value in the diagnosis of purulent meningitis in children.

Objective:To describe the differences in body mass index (BMI) distribution in adult twins registered in Chinese National Twin Registry (CNTR), and provide evidence for the risk factor analysis and prevention and control of overweight or obesity.Methods:A total of 32 725 twin pairs aged 18 years and above who completed the questionnaire survey during 2010-2018 and had complete registered information in CNTR and normal body weight and length were included in the analysis on the population and region specific distributions of BMI of twin pairs and the difference in BMI in twin pairs.Results:The twin pairs included in the analysis were aged (34.6±12.4) years, the twin pairs of same gender accounted for 79.7%. The average BMI was 22.5 kg/m 2. The overall prevalence of obesity and overweight was 4.9% and 23.7%, respectively. Participants who were men, 50-59 years old, married, had lower education level, and lived in northern China had higher overweight rate and obesity rate ( P<0.001). The difference in overweight or obesity prevalence between monozygotic (MZ) twin pars and dizygotic (DZ) twin pairs was not significant, but firstborn twin pairs had slightly higher rates of overweight and obesity than later-born twin pairs ( P<0.05). The analysis in same gender-twin pairs indicated that the difference in BMI was associated with age (trend test: P<0.001), and the difference was more obvious in DZ twin pair in MZ pair and this difference increased with age. The concordant rate of BMI was higher in MZ twin pairs than DZ twin pairs ( P<0.05). Conclusion:The distribution of BMI of twin pairs varied with population and region and BMI varied with age due to its genetic nature.
