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 evaluate the anesthetic efficacy of etomidate target-controlled infusion (TCI) in combination with remifentanil in patients undergoing gynecological laparoscopy.Methods Sixty ASA physical status Ⅰ or Ⅱ patients,aged 25-56 yr,with body mass index 18-27 kg/m2,undergoing elective gynecological lapa-roscopy,were equally and randomly divided into 2 groups:propofol TCI combined with remifentanil group (group PR) and etomidate TCI combined with remifentanil group (group ER).Anesthesia was induced with iv injection ofmidazolam 0.1 mg/kg,fentanyl 4 μg/kg and cisatracurium 0.15 mg/kg in both groups,and with TCI of propofolwith the target effect-site concentration (Ce) of 2.5 μg/ml in group PR or with TCI of etomidate (Ce 0.8 μg/ml) ingroup ER.The patients were mechanically ventilated after endotracheal intubation.Anesthesia was maintained withTCI of propofol (Ce 2.0-2.5 μg/ml) in group PR or with etomidate (Ce 0.5-0.7 μg/ml) in group ER,and with ivinfusion of remifentanil 0.1-0.2 μg· kg-1 · min-1 and intermittent iv boluses of cisatracurium 5 mg.BIS value was maintained at 40-60.Before anesthesia (baseline,T0),at the end of operation (T1),and at 24 and 48 h after operation (T2-3),venous blood samples were collected for determination of serum cortisol and aldosterone concentrations by radioimmunoassay.The emergence time,extubation time and requirement for vasoactive agents during operation were recorded.The development of injection pain and muscle twitch during induction of anesthesia,intraoperative awareness,and post-operative agitation,nausea and vomiting were also recorded.Results Compared with the baseline value at T0,the serum cortisol concentration was significantly decreased at T1 in group ER (P <0.05),while no significant change was found in serum aldosterone concentrations at each time point in the two groups (P > 0.05).Compared with group PR,the requirement for vasoactive agents and incidence of injection pain were significantly decreased,and the incidence of muscle twitch was increased (P < 0.05),and no significant change was found in the emergence time,extubation time,and incidences of post-operative agitation,nausea and vomiting in group ER (P > 0.05).Conclusion Compared with propofol TCI in combination with remifentanil,etomidate TCI combined with remifentanil is helpful in maintaining the hemodynamics stable and exerts transient inhibition of adrenocortical function with less injection pain in patients undergoing gynecological laparoscopy.
