Objective: To explore the safety and short-term efficacy of venetoclax combined with azacitidine (Ven+AZA) in previously untreated patients unfit for standard chemotherapy and patients with relapsed/refractory (R/R) acute myeloid leukemia (AML) in China. Methods: A retrospective study was conducted in 60 previously untreated patients unfit for standard chemotherapy and patients with R/R AML who received Ven+ AZA (venetoclax, 100 mg D1, 200 mg D2, 400 mg D3-28; azacitidine, 75 mg/m(2) D1- 7) at the Peking University Institute of Hematology from June 1, 2019 to May 31, 2021. The incidence of adverse events, complete remission (CR) /CR with incomplete hematological recovery (CRi) rate, objective remission rate (ORR) , and minimal residual disease (MRD) status in patients with different risk stratification and gene subtypes were analyzed. Results: The median age of the patients was 54 (18-77) years, 33 (55.0%) were males, and the median follow-up time was 4.8 (1.4-26.3) months. Among the 60 patients, 24 (40.0%) were previously untreated patients unfit for standard chemotherapy, and 36 (60.0%) were R/R patients. The median mumber cycles of Ven+AZA in the two groups were both 1 (1-5) . According to the prognostic risk stratification of the National Comprehensive Cancer Network, it was divided into 8 cases of favorable-risk, 2 cases of intermediate risk, and 14 cases of poor-risk. In previously untreated patients unfit for standard chemotherapy, after the first cycle of Ven+AZA, 17/24 (70.8%) cases achieved CR/CRi, 3/24 (12.5%) achieved partial remission (PR) , and the ORR was 83.3%. Among them, nine patients received a second cycle chemotherapy and two received a third cycle. Among CR/CRi patients, 8/17 (47.1%) achieved MRD negativity after two cycles of therapy. In the R/R group, after the first cycle of Ven+AZA, 21/36 (58.3%) cases achieved CR/CRi (7/21 achieved MRD negativity) , 3 achieved PR, and the ORR was 66.7%. Among R/R patients, 12 were treated for more than two cycles. There were no new CR/CRi patients after the second treatment cycle, and 14 cases (66.7%) achieved MRD negativity. According to the time from CR to hematological recurrence, the R/R group was divided into 12 cases in the favorable-risk group (CR to hematological recurrence ≥18 months) and 24 in the poor-risk group (CR to hematological recurrence<18 months, no remission after one cycle of therapy, and no remission after two or more cycles of therapy) . Eleven of 24 (45.8%) cases achieved CR/CRi after one cycle of Ven+AZA in the poor-risk R/R group, and 10 of 12 (83.3%) achieved CR/CRi in the favorable-risk R/R group, which was significantly superior to the poor-risk group (P=0.031) . After one cycle of treatment, 13 patients with IDH1/2 mutations and 4 that were TP53-positive all achieved CR/CRi. The CR/CRi rate of 18 patients with NPM1 mutations was 77.8%. Five patients with RUNX1-RUNX1T1 combined with KIT D816 mutation (two initial diagnoses and three recurrences) had no remission. Ven+ AZA was tolerable for AML patients. Conclusion: Ven+AZA has acceptable safety in previously untreated patients unfit for standard chemotherapy, patients with R/R AML can achieve a high response rate, and some patients can achieve MRD negativity. It is also effective in NPM1-, IDH1/IDH2-, and TP53-positive patients. The long-term efficacy remains to be observed.

Objective: To evaluate the efficacy of consolidation chemotherapy combined with allogeneic natural killer (NK) cell infusion in the treatment of low or intermediate-risk (LIR) acute myeloid leukemia (AML) . Methods: A cohort of 23 LIR AML patients at hematologic complete remission (CR) received NK cell transfusion combined with consolidation chemotherapy after 3 consolidation courses from January 2014 to June 2019 were reviewed. Control group cases were concurrent patients from Department of Hematology, and their gender, age, diagnosis, risk stratification of prognosis, CR and the number of courses of consolidate chemotherapy before NK cell transfusion were matched with LIR AML patients. Results: A total of 45 times of NK cells were injected into 23 LIR AML patients during 4 to 7 courses of chemotherapy. The median NK cell infusion quantity was 7.5 (6.6-8.6) ×10(9)/L, and the median survival rate of NK cells was 95.4% (93.9%-96.9%) . Among them, the median CD3(-)CD56(+) cell number was 5.0 (1.4-6.4) ×10(9)/L, accounting for 76.8% (30.8%-82.9%) ; The number of CD3(+) CD56(+) cells was 0.55 (0.24-1.74) ×10(9)/L, accounting for 8.8% (4.9%-20.9%) . Before NK cell infusion, the number of patients with positive MRD in the treatment and control groups were 9/23 (39.1%) and 19/46 (41.3%) (χ(2)=0.030, P=0.862) respectively. After NK infusion, There was no significant difference in terms of MRD that went from negative to positive between the treatment and the control groups (14.3% vs 22.2%, χ(2)=0.037, P=0.847) . In the treatment group, 66.7% (6/9) of the MRD were converted from positive to negative, which was significantly higher than that in the control group (10.5%, 2/19) (χ(2)=6.811, P=0.009) . Morphological recurrence occurred in 1 case of MRD negative in the treatment group and 2 cases of MRD positive in the control group. By the end of follow-up, the median follow-up was 35 (10-59) months, the number of patients with morphological recurrence in the treatment group was 30.4% (7/23) , which was significantly lower than that in the control group (50.2%, 24/46) (χ(2)=2.929, P=0.087) , although there was no statistically significant difference between the two groups. There was no significant difference on MRD-negative between the treatment and the control groups (43.5% vs 43.5%, χ(2)=1.045, P=0.307) . The 3-year leukemia-free survival was better in the treatment group [ (65.1±11.1) %] than that in the control group [ (50.0±7.4) %] (P=0.047) . The 3-year overall survival in the treatment and control groups were (78.1±10.2) % and (65.8±8.0) % (P=0.212) , respectively.

Meta-analysis and trial sequential analysis of modified Sangbaipi Decoction for treating acute exacerbation of chronic obstructive pulmonary disease / 中国中药杂志

The randomized controlled trials about modified Sangbaipi Decoction in the treatment of acute exacerbation of chronic obstructive pulmonary disease( AECOPD) patients were collected from 7 databases( PubMed,CNKI,et al) from the establishment to December 5,2018. All the studies searched were strictly evaluated. Literatures were independently screened by two researchers according to the inclusion and exclusion criteria,and the methodological quality of included studies was evaluated. To systematically review the efficacy of modified Sangbaipi Decoction in treating AECOPD,the Meta-analysis and trial sequential analysis were conducted by using Stata/SE 14. 0 and TSA 0. 9. 5. 10 Beta,respectively. A total of 25 RCTs involving 1 784 patients were included. According to the results of Meta-analysis,compared with the control groups,the trial group had a higher clinical efficacy in AECOPD patients( RR =1. 18,95%CI[1. 13,1. 22],P = 0),improved pulmonary functions including forced expiratory volume in one second( FEV1,WMD =0. 44,95%CI[0. 01,0. 87],P = 0. 046),and the forced vital capacity( FVC,WMD = 0. 42,95%CI[0. 07,0. 22],P = 0),but no statistical significance in the percentage of forced expiratory volume in one second( FEV1%,P = 0. 067) and the first seconds breathing volume percentage of forced vital capacity( FEV1/FVC,P = 0. 238); it improved the arterial oxygen partial pressure( PaO2,SMD =0. 85,95%CI[0. 41,1. 30],P = 0) and decreased the arterial partial pressure of carbon dioxide( PaCO2,SMD =-0. 94,95% CI[-1. 70,-0. 18],P= 0. 016); and in terms of inflammatory markers,it improved the white blood cell count( WBC,WMD=-0. 94,95%CI[-1. 17,-0. 70],P = 0). The trial sequential analysis showed that the studies included with the improvement of clinical efficacy had passed the conventional and TSA threshold,so as to further confirm the evidence. According to the findings,in addition to conventional Western medicine treatment,modified Sangbaipi Decoction could improve the efficiency in treating acute exacerbation patients with chronic obstructive pulmonary disease,increase PaO2,and decrease PaCO2,with a high safety but no effect on pulmonary function. However,restricted by the low quality of studies included,this conclusion shall be further verified by more high-quality clinical trials.

All the studies searched were strictly evaluated and independently screened by two researchers according to the inclusion and exclusion criteria,and the methodological quality of included studies was evaluated. In order to systematically review the efficacy and safety of modified Sanzi Yangqin Decoction for treating AECOPD,the Meta-analysis and trial sequential analysis were conducted by using Stata/SE 14. 0 and TSA 0. 9. 5. 10 Beta,respectively. A total of 22 RCTs involving 2 012 patients were included. The results of Meta-analysis suggested that: as compared with the control group,the clinical symptoms in AECOPD patients were improved( RR = 1. 19,95%CI[1. 15,1. 24],P = 0); the pulmonary functions including forced expiratory volume in one second( FEV_1)( SMD= 0. 96,95%CI[0. 39,1. 52],P= 0. 001),the percentage of forced expiratory volume in one second( FEV_1%)( SMD =0. 80,95%CI[0. 20,1. 41],P = 0. 009),forced vital capacity( FVC)( SMD = 0. 69,95% CI[0. 06,1. 31],P = 0. 032),first seconds breathing volume percentage of forced vital capacity( FEV_1/FVC) were improved( SMD = 0. 81,95%CI[0. 64,0. 97],P = 0);the arterial oxygen partial pressure( PaO_2) was improved( SMD= 0. 87,95%CI[0. 41,1. 32],P= 0); the arterial partial pressure of carbon dioxide( PaCO_2) was decreased( SMD =-0. 91,95%CI[-1. 33,-0. 49],P = 0) in the trial group. In addition,the incidence of adverse reactions in the experimental group was low,and there were no serious adverse events. The trial sequential analysis( TSA) showed that the studies included in the improvement of clinical efficacy had passed the conventional and TSA threshold at the same time,further confirming the efficacy of trial group. This research showed that,conventional Western medicine treatment,combined with modified Sanzi Yangqin Decoction in treating acute exacerbation patients with chronic obstructive pulmonary disease could improve the clinical efficiency and pulmonary functions,improve the PaO_2,decrease the PaCO_2,with a high safety. However,the quality of existing research is low,requiring more high quality clinical trials for further validation.

A low-pass filter of 300 Hz improved the detection of pacemaker spike on remote and bedside electrocardiogram / 中华医学杂志(英文版)

BACKGROUND@#The current upper-frequency cutoff of 150 Hz sometimes causes loss of pacemaker spike and misdiagnosis. We hypothesized that low-pass filter (LPF) other than 150 Hz could improve the detection of pacemaker spike. This study aimed to examine the effect of different LPF on pacemaker spike detection in remote and bedside electrocardiogram (ECG).@*METHODS@#Patients with permanent pacemaker implantation were included during routine follow-up. Standard 12-lead ECGs at 6 different upper-frequency cutoff (40, 100, 150, 200, 300, and 400 Hz) were collected. All ECGs were then transmitted to the remote clinic center. Ventricular and atrial pacing were analyzed by 2 independent medical practitioners.@*RESULTS@#A total of 88 patients' ECGs were analyzed (mean age 73.8 ± 10.2 years and 85 with dual-chamber pacemakers). About 75.3% (64/85) of patients were diagnosed as atrial pacing by pacemaker programming. Among 6 different upper-frequency cutoff, the 300 Hz turned out to perform best in detecting atrial-paced spike (area under the curve [AUC] = 0.73, 95% confidence interval [CI]: 0.61-0.84 vs. 0.56, 95% CI: 0.61-0.84 at 150 Hz; P = 0.002) on bedside ECGs. Using programming as the golden standard, the 300 Hz LPF has a sensitivity of 59.4%, specificity of 85.7%, positive predictive value of 92.7% and negative predictive value of 40.9% on bedside ECGs. As for the ventricular pacing, the 300 Hz LPF also had a higher accuracy (AUC = 0.93; 95% CI = 0.84-1.00) than that at 150 Hz (AUC = 0.86; 95% CI: 0.77-0.94; P < 0.001) in detecting ventricular-paced spike on bedside ECGs. The results of remote ECGs were similar with bedside ECGs.@*CONCLUSIONS@#A filter of 300 Hz cutoff may be recommended for ECG spike detection. With the recommended parameter, remote ECG can perform as well as bedside ECG.

Consultation rate,reasons for referral,psychiatric diagnoses,length of stay,and medical expense were compared between different periods.Results Among 1230 geriatric inpatients,383 patients were enrolled in liaison psychiatric service,and 511 individual consultations happened.The consultation rate for T1 and T2 were 19.7% and 33.8%,respectively (P=0.000).The dominating reasons for referral were current emotional symptoms (30.4%) and current psychiatric symptoms (28.3%) in T1 and current emotional symptoms (65.3%) and medically unexplained symptoms (12.8%) in T2 (P=0.000). For length of stay,consultation group lasted for (199.2±40.0) days,and non-consultation group lasted for (71.3±16.6) days(P=0.004) in T1;(22.0±2.4) days and (22.6±1.6) days(P=0.834) in different groups in T2 respectively. The medical expense were (243 000±44 000) RMB for consultation group and (79 000±18 000) RMB for non-consultation group(P=0.040) in T1 and (18 000±2 000) RMB and (21 000±1 000) RMB (P=0.302) in different groups in T2 respectively. The prevalence rate for psychiatric disorders revealed by liaison psychiatrists was 15.8% in T1 and 29.8%in T2 (P=0.000) in the geriatric ward. Conclusions Elderly inpatients are vulnerable population for psychiatric disorders. Therefore,psychiatrist should be an important member in geriatric interdisciplinary team. Combination of comprehensive geriatric assessment,psychiatric consultation and geriatric interdisciplinary team is very efficient model in general hospital settings to improve the accessibility of psychiatric services in elderly in China.

Analysis of In-hospital Neonatal Death in the Tertiary Neonatal Intensive Care Unit in China: A Multicenter Retrospective Study / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Globally, the proportion of child deaths that occur in the neonatal period remains a high level of 37-41%. Differences of cause in neonate death exist in different regions as well as in different economic development countries. The specific aim of this study was to investigate the causes, characteristics, and differences of death in neonates during hospitalization in the tertiary Neonatal Intensive Care Unit (NICU) of China.</p><p><b>METHODS</b>All the dead neonates admitted to 26 NICUs were included between January l, 2011, and December 31, 2011. All the data were collected retrospectively from clinical records by a designed questionnaire. Data collected from each NICU were delivered to the leading institution where the results were analyzed.</p><p><b>RESULTS</b>A total of 744 newborns died during the 1-year survey, accounting for 1.2% of all the neonates admitted to 26 NICUs and 37.6% of all the deaths in children under 5 years of age in these hospitals. Preterm neonate death accounted for 59.3% of all the death. The leading causes of death in preterm and term infants were pulmonary disease and infection, respectively. In early neonate period, pulmonary diseases (56.5%) occupied the largest proportion of preterm deaths while infection (27%) and neurologic diseases (22%) were the two main causes of term deaths. In late neonate period, infection was the leading cause of both preterm and term neonate deaths. About two-thirds of neonate death occurred after medical care withdrawal. Of the cases who might survive if receiving continuing treatment, parents' concern about the long-term outcomes was the main reason of medical care withdrawal.</p><p><b>CONCLUSIONS</b>Neonate death still accounts for a high proportion of all the deaths in children under 5 years of age. Our study showed the majority of neonate death occurred in preterm infants. Cause of death varied with the age of death and gestational age. Accurate and prompt evaluation of the long-term outcomes should be carried out to guide the critical decision.</p>

Mortality and Morbidity of Extremely Low Birth Weight Infants in the Mainland of China: A Multi-center Study / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>With the progress of perinatal medicine and neonatal technology, more and more extremely low birth weight (ELBW) survived all over the world. This study was designed to investigate the short-term outcomes of ELBW infants during their Neonatal Intensive Care Unit (NICU) stay in the mainland of China.</p><p><b>METHODS</b>All infants admitted to 26 NICUs with a birth weight (BW) < l000 g were included between January l, 2011 and December 31, 2011. All the data were collected retrospectively from clinical records by a prospectively designed questionnaire. The data collected from each NICU transmitted to the main institution where the results were aggregated and analyzed. Categorical variables were performed with Pearson Chi-square test. Binary Logistic regression analysis was used to detect risk factors.</p><p><b>RESULTS</b>A total of 258 ELBW infants were admitted to 26 NICUs, of whom the mean gestational age (GA) was 28.1 ± 2.2 weeks, and the mean BW was 868 ± 97 g. The overall survival rate at discharge was 50.0%. Despite aggressive treatment 60 infants (23.3%) died and another 69 infants (26.7%) died after medical care withdrawal. Furthermore, the survival rate was significantly higher in coastal areas than inland areas (53.6% vs. 35.3%, P = 0.019). BW < 750 g and GA < 28 weeks were the largest risk factors, and being small for gestational age was a protective factor related to mortality. Respiratory distress syndrome was the most common complication. The incidence of patent ductus arteriosus, intraventricular hemorrhage, periventricular leukomalacia, bronchopulmonary dysplasia, retinopathy of prematurity was 26.2%, 33.7%, 6.7%, 48.1%, and 41.4%, respectively. Ventilator associated pneumonia was the most common hospital acquired infection during hospitalization.</p><p><b>CONCLUSIONS</b>Our study was the first survey that revealed the present status of ELBW infants in the mainland of China. The mortality and morbidity of ELBW infants remained high as compared to other developed countries.</p>
