Objective To evaluate the reliability and validity of the Chinese version of the Repeatable Battery for the Assessment of Neuropsychological Status(RBANS)in patients with maintenance hemodialysis(MHD).Methods The general information and medical history of 84 MHD patients were collected,and the Mini-Mental State Exam(MMSE),Montreal Cognitive Assessment Scale(MoCA),and RBANS were conducted.The reliability of the scale was assessed by Cronbach α and split-half reliability.The structure and convergent validity of the scale were assessed by confirmatory factor analysis,and the RBANS scores'correlation to MoCA and MMSE scores was analyzed by Spearman correlation analysis.The predictive value of the RBANS total score on cognitive impairment(CI)was analyzed by receiver operating characteristic(ROC)curve.Results The Cronbach's alpha coefficient of the RBANS total scale was 0.896,split-half reliability was 0.911,and reliability for the five dimensions of the RBANS ranged from 0.618 to 0.791.Confirmatory factor analysis indicated that the overall fit of the five-dimensional model of the RBANS scale was acceptable(χ2/df=1.587,root mean square error of approximation=0.084,comparative fit index=0.967,incremental fit index=0.968,Tucker-Lewis index=0.947,goodness of fit index=0.891).The average variance extracted(AVE)for the five dimensions of the RBANS ranged from 0.525 to 0.863,while the composite reliability(CR)ranged from 0.733 to 0.926,indicating good convergent validity of the scale.Furthermore,Spearman correlation analysis revealed that the total RBANS score was negatively correlated to the age of MHD patients and positively correlated to years of education,as well as the total scores of MMSE and MoCA(all P<0.01).The ROC curve analysis indicated that the area under the curve(AUC)for the total RBANS score in predicting CI was 0.891(P<0.01),suggesting a high predictive value.Conclusion The Chinese version of RBANS has good reliability and validity in MHD patients,and can be used as a measure of cognitive function in MHD patients.

Acute myeloid leukemia (AML) is the most common type of leukemia at present. Although clinical treatment has a certain effect on this disease, most patients still die of relapse or its treatment related diseases. Nowadays, chimeric antigen receptor (CAR) T cells therapy technology has developed rapidly, and has become a hot topic in tumor immunotherapy. The high expression of CD123 in AML cells, low expression or non expression in normal hematopoietic stem cells and tissues, make more and more researchers focus on the technology of CD123+cell immunotherapy. Some studies have confirmed that CD123 CAR-T cells have a certain effect on AML, which provides a new way for clinical treatment of relapsed or refractory AML. This review summarizes the structure, production and delivery methods of CD123 CAR-T cells, and the current research status and shortcomings of CD123 CAR-T cells.

Objective To explore the relationship between the respiratory disturbance index (RDI) detected by cardiopulmonary coupling (CPC) and all parameters of polysomnography (PSG), and to analyze the correlation of the two different analytical techniques for the interpretation of sleep breathing events.Methods In this case-control study, the patients′ CPC and PSG were simultaneously recorded at the Sleep Clinic at Changzheng Hospital from Janunary 2016 to December 2016.Effective recordings were obtained from 292 patients (male/female: 173/119).According to PSG, these patients were divided into two groups: obstructive sleep apnea hyponea syndrome (OSAHS) group (n=173, aged (50.1±13.3) years) and non-OSAHS group (n=119, aged (50.5±11.7) years).All the PSG parameters and the RDI detected by CPC were compared between the two groups.Pearson correlation was used to analyze the relationship between the CPC-RDI and polysomnography parameters, and Bland-Altman chart was used to test the correlation of the two methods.The receiver operator characteristic curve was used to research the value of CPC-RDI in diagnosis of OSAHS.Results The OSAHS group showed higher levels of total sleep time (TST, (445.94±82.64) min), apnea times ((108.16±35.70)/h), hypopnea rate ((55.62±17.44)/h), apnea hyponea index (AHI, (22.78±20.73)/h), Epworth Sleeping Scale (ESS) scores ((11.21±5.30) scores), CPC-RDI ((32.98±22.19)/h) compared with the non-OSAHS group ((417.21±96.10) min,t=2.730;(7.89±5.41)/h,t=30.384;(11.05±2.23)/h, t=27.709;(5.51±3.11)/h,t=9.014;(7.61±2.29)scores,t=6.973;(11.16±8.63)/h,t=10.205, all P<0.01), and a significant decrease in N1 latency ((14.79±9.29) min vs (18.18±8.98)min, t=-3.106), N3% ((6.53±4.95)% vs(8.83±7.29)%,t=-3.212) and the lowest oxygen saturation (SaO2;(77.91±12.21)% vs(92.72±5.17)%, t=-12.479, all P<0.05 respectively).Pearson correlation analysis indicated that RDI was positively correlated with TST, N2 sleeping time, N3 sleeping time, AHI, microarousals index, leg movements index, and ESS scores (P<0.01 respectively).Remarkably, the correlation between CPC-RDI and PSG-AHI was excellent (r=0.801, P<0.01), and CPC-RDI was negatively correlated with lowest SaO2 (r=-0.765, P<0.01).Bland-Altman showed that the points in the limits of agreement accounted for more than 95% of all points.If CPC-RDI is higher than 18.95, the subjects were more likely with OSAHS.The sensitivity was 62.9% and the specificity was 88.7%.In addition, the enhanced low-frequency coupling parameters in the CPC analysis technique can clearly analyze the central respiratory rhythm disturbance.Conclusions CPC technology is an effective assessment technology to diagnose sleep-disordered breathing, and correlates well with AHI detected by traditional PSG.It shows the advantage of screening for central sleep apnea.

Objective To investigate the characteristics of HRV parameters in different posture of patients with positional obstructive sleep apnea syndrome (POSAS) and the relationship between apnea hypopnea index (AHI),minimum oxygen saturation (LSaO2) and HRV parameters.Methods A case-control study was conducted to compare the characteristics of heart rate variability between supine and lateral positions in POSAS patients.Results Compared with lateral position,POSAS group showed higher levels of heart rate variability indexes (P ＜ 0.05).Pearson correlation analysis indicated that AHI was positively correlated with SDNN、SDANN、ULF、LF/HF (P ＜ 0.05 or P ＜ 0.01).Remarkably,the correlation between AHI and LF/HF was excellent (r =0.437,P ＜ 0.01),and negatively correlated with HF(r =-0.306,P ＜ 0.05).Similarly,LSaO2 was negatively correlated with LF/HF.Conclusion The sleep-disordered breathing in supine position of POSAS patients is significantly heavier than that in lateral decubitus position.
