Abstract
Objective: Pelvic high-resolution magnetic resonance imaging (MRI) has now become a standard method for evaluating the efficacy of neoadjuvant treatment for locally advanced rectal cancer (LARC). However, this traditional morphological qualitative assessment method based on T2-weighted imaging (T2WI) is not effective in predicting pathological complete remission (pCR). The purpose of this study is to investigate whether combining the magnetic resonance tumor regression grade (mrTRG) with apparent diffusion coefficient (ADC) can improve diagnostic value for pCR after preoperative neoadjuvant chemoradiotherapy (nCRT) of LARC. Methods: This was a diagnostic study. Clinicopathological data of 134 LARC patients who received nCRT and radical surgery in the First Affiliated Hospital of Kunming Medical University from January 2017 to December 2019 were retrospectively analyzed. All the patients underwent MRI which included T2WI and DWI sequences before and 8 weeks after nCRT. Two radiologists independently drew ROIs on T2WI and DWI to estimate mrTRG stage and calculate the mean ADC value. Receiver operating characteristics (ROC) method was applied to evaluate the predict value of mrTRG combined with mean ADC value for pCR. Results: Of 134 LARC patients, 85 were male and 49 were female with median age of 58 (28-82) years. After nCRT, MRI suggested 21 patients (15.7%) had clinical complete remission (cCR), e.g. mrTRG stage 1-2. Postoperative pathology revealed 31 (23.1%) patients had pCR. The evaluations of mrTRG and ADC value by the two readers were highly consistent, and the intra-group correlation coefficients were 0.83 (95% CI: 0.703-0.881) and 0.96 (95% CI: 0.989-0.996), respectively. There was a negative correlation between mrTRG and pCR (r(s)=-0.505, P<0.01), and a positive correlation between mean ADC value and pCR (r(s)=0.693, P<0.01). The ROC curve showed that mrTRG alone had a medium predictive value for pCR, with an area under the curve (AUC) of 0.832 (95% CI: 0.743-0.921); the mean ADC value had a higher predictive value for pCR, with AUC of 0.906 (95% CI: 0.869-0.962). The predictive value of the combined model of mrTRG and ADC value for pCR was significantly better than that of mrTRG alone (P=0.015), and the AUC was 0.908 (95% CI: 0.849-0.968). Conclusion: Both mrTRG and mean ADC value can be non-invasive methods to predict the efficacy of nCRT for LARC. Combining the mean ADC value with mrTRG can result in better pCR prediction.

Abstract
Objective The etiology and pathogenesis of preeclampsia (PE) remain unclear, and ideal biomarkers for the early detection of PE are scarce. The involvement of the competing endogenous RNA (ceRNA) hypothesis in PE is only partially understood. The present study aimed to delineate a regulatory network in PE comprised of messenger RNAs (mRNAs), circular RNAs (circRNAs), long non-coding RNAs (lncRNAs), and microRNAs (miRNAs) via ceRNA profiles from human umbilical vein endothelial cells (HUVECs) to further reveal the pathogenesis of PE and potential biomarkers. Methods Differentially expressed mRNAs, circRNAs, and lncRNAs were detected in HUVECs from early onset preeclampsia (EOPE) cases (n = 4) and normal pregnancies (n = 4) by microarray analysis. Bioinformatics analysis was performed to systematically analyze the data, and a relevant ceRNA network was constructed. RNAs (ANGPT2, LIPG, hsa_circ_0025992, hsa_circ_0090396, hsa_circ_0066955, hsa_circ_0041203, hsa_circ_0018116, lnc-C17orf64-1:1, lnc-SLC27A2-2:1, and lnc-UEVLD-5:1) were validated by quantitative real-time PCR (qRT-PCR) in 10 pairs of HUVECs and placental tissues from PE patients and normal pregnancies. Furthermore, expression of hsa_circ_0025992 was detected in maternal peripheral blood samples from PE patients (n = 24) and normal pregnancies (n = 30) to confirm its potential as a novel biomarker. The receiver operating characteristic (ROC) curve was applied to analyze its diagnostic value. Results Compared with HUVECs from normal pregnancies, HUVECs from EOPE cases had 33 differentially expressed mRNAs (DEmRNAs), 272 DEcircRNAs, and 207 DElncRNAs. GO and KEGG analyses of the DERNAs revealed the biological processes and pathways involved in PE. Based on the microarray data and the predicted miRNAs, a ceRNA network was constructed with four mRNAs, 34 circRNAs, nine lncRNAs, and 99 miRNAs. GO and KEGG analyses of the network reinforced the crucial roles of metabolic disorders, the p53 and JAK/STAT signaling pathways in PE. In addition, ROC analysis indicated that hsa_circ_0025992 could be used as a novel biomarker for PE. Conclusion A novel ceRNA network was revealed in PE, and the potential of hsa_circ_0025992 to serve as a new biomarker was confirmed.

Abstract
We report on a precision energy loss measurement and theoretical investigation of 100 keV/u helium ions in a hydrogen-discharge plasma. Collision processes of helium ions with protons, free electrons, and hydrogen atoms are ideally suited for benchmarking plasma stopping-power models. Energy loss results of our experiments are significantly higher than the predictions of traditional effective charge models. We obtained good agreement with our data by solving rate equations, where in addition to the ground state, also excited electronic configurations were considered for the projectile ions. Hence, we demonstrate that excited projectile states, resulting from collisions, leading to capture-, ionization-, and radiative-decay processes, play an important role in the stopping process in plasma.

Abstract
PURPOSE Our and other's studies showed that administration of neuropeptide galanin may mitigate insulin resistance via promoting glucose transporter 4 (GLUT4) expression and translocation in rats. The objective of this study is to investigate whether galanin receptor 2 (GAL2-R) in brain mediates the ameliorative effect of galanin on insulin resistance in adipose tissues of type 2 diabetic rats. METHODS In this study galanin, GAL2-R agonist M1145 and GAL2-R antagonist M871 were respectively or cooperatively injected into intracerebroventricles of type 2 diabetic rats once a day for successive fifteen days. Then the plasma and fat tissues of rats were used to estimate the alterations of insulin resistance indexes. RESULTS The central administration of galanin enhanced 2-deoxy-[3H]-D-glucose, peroxisome proliferator-activated receptor γ and adiponectin levels, food intake and body weight, GLUT4 mRNA expression and GLUT4 concentration in plasma membranes, as well as homeostasis model assessment-insulin resistance index. Those effects of galanin may be blocked by M817, and imitated by M1145 except for food intake and body weight. CONCLUSION Those results suggest that central GAL2-R mediates the beneficial effects of galanin on insulin sensitivity in type 2 diabetic rats. GAL2-R agonist may be taken as a potential antidiabetic agent to treat insulin resistance and type 2 diabetes.

Abstract
Objective: To investigate the current status of the diagnosis and treatment of pulmonary cryptococcosis in respiratory medicine and improve the understanding of the clinical characteristics of HIV-negative pulmonary cryptococcosis in China. Methods: A prospective multi-center open cohort study was designed to screen for pulmonary cryptococcosis in the general wards and intensive care units of the Department of Respiratory Diseases in 22 hospitals. The HIV-negative patients with positive cryptococcal etiological diagnosis based on smear culture, antigen detection and histopathology were enrolled in the study. The clinical data of enrolled patients were collected and analyzed. Results: A total of 457 cases of pulmonary cryptococcosis were enrolled, among which 3.28% (15/457) were disseminated infections. The case fatality rate was 0.88% (4/457). The majority of the cases were diagnosed by histopathological examinations (74.40%, 340/457) and cryptococcus antigen detection (37.64%, 172/457). Patients with pulmonary cryptococcosis accounted for 2.04‰ (457/223 748) of the total hospitalized patients in the Department of Respiratory Diseases during the same period, and the ratio was the highest in south and east China. Meanwhile, 70.24% (321/457) of the patients had no underlying diseases, while 87.75% (401/457) were found to have immunocompetent status. Cough and expectoration were the most common clinical symptoms in patients with pulmonary cryptococcosis. However, 25.16% (115/457) of the patients had no clinical symptom or physical signs. In terms of imaging features on pulmonary CT, multiple pulmonary lesions were more common than isolated lesions, and there were more subpleural lesions than perihilar or medial lesions. Morphologically, most of the lesions were middle-sized nodules (1-5 cm) or small-sized nodules (3 mm to 1 cm). The sensitivity of serum cryptococcus antigen test was 71.99% (203/282). Moreover, antigen-positive patients differed from antigen-negative patients in terms of basic immune status, clinical symptoms, imaging features and infection types. Meanwhile, immunocompromised patients differed from immunocompetent patients in terms of clinical symptoms, physical signs, infection-related inflammation indicator levels, imaging features, serum cryptococcus antigen positive rate and prognosis. Conclusions: The majority of cases of HIV-negative pulmonary cryptococcosis in China had no underlying disease or immunocompromised status, and the overrall prognosis was favorable. However, early diagnosis of HIV-negative pulmonary cryptococcosis remains challenging due to the complicated manifestations of the disease.

Abstract
Objective: To investigate the clinicopathological characteristics of eosionphilic Chromophobe renal cell carcinoma (eChRCC), and differences in morphology, immunophenotype and clinical prognosis betweeneChRCC, renal oncocytoma(RO) and classic Chromophobe renal cell carcinoma (cChRCC). Methods: The clinicopathologic data of 17 patients diagnosed as eChRCC from the Affiliated Hospital of Qingdao University (13 cases) and 971 Hospital of PLA Navy (4 cases) from October 2006 to February 2019 were collected. Immunohistochemical analysis was carried out to compare the immunophenotypes between 17 cases with ChRCC, 27 cases with RO and 30 cases with cChRCC. Resuls: Among the 17 patients, seven were males and ten were females, and the age ranged from 40 to 75 years (median 54 years). Clinically, 15 cases of 17 were found accidentally by physical examination. The tumor size ranged from 1.8 cm to 10.0 cm (average 5.7 cm) and the cut surface of 15 cases were solid, one case was solicl and cystic, and one was cystic. Most showed gray to red, and partially soft, gray to yellow appearances. Microscopically, most tumors presented solid growth pattern with vary number of alveolar structures (12 cases). Some were predominately characterized by cystic structure (3 cases), alveolar structure(1 case) and microcapsule structure (1 case). There were boundaries with varying degrees of clarity between tumor cells in 16 cases. The cytoplasm of tumor cells was eosinophilic and the nuclei were small round or irregular with focal perinuclear haloes in 14 cases. Large polygonal cells with light-stained cytoplasm appeared focally in 9 cases, and edematous areas with scarce tumor cells were found in 4 cases. Among 7 cases, 4 cases focally invaded peripheral renal parenchyma, 2 cases invaded adipose tissues outside the renal capsule, and 1 case presented invasion of renal sinus. Immunohistochemically, all cases were moderate to strong positive for EMA and claudin-7. CK7, CD117 and Ksp-cad were highly expressed with the expression rates of 12/17, 15/17, 14/17, respectively. Cyclin D1, AMACR, CD10, S100A1, and RCC were rarely expressed with the expression rates of 4/17, 3/17, 4/17, 1/17 and 1/17, respectively. On the contrary, all cases were negative for vimentin, CAⅨ, HMB45 and Melan A. The Ki-67 proliferation index of the 17 cases was 1%‒5%. Follow-up data were available for all 17 patients from 7 to 154 months. Among them, 15 patients were alive without tumor recurrence or metastasis, one patient died of pulmonary metastasis after 31 months of surgery and one patient died of hepatic metastasis after 38 months of surgery. Conclusion: eChRCC has overlapping morphology and immunophenotype with RO. eChRCC is characterized by solid nest or alveolar structure, distinct border between tumor cells, perinuclear halos and lacking of interstitial looseness and edema. Scattered large polygonal cells with light-stained cytoplasm in tumor tissue play a significant role in the diagnosis of eChRCC. The positive expression of CK7, CD117, claudin-7 and Ksp-cad, and negative expression of cyclin D1, S100A1 are helpful to the diagnosis and differential diagnosis of eChRCC. The prognosis of eChRCC after complete surgical resection is excellent and few cases may have long-term metastasis. There is no significant difference in prognosis between eChRCC and cChRCC, but eChRCC shows better outcome than RO.

Abstract
Abstract
Objectives
This study evaluated whether coronary artery calcium scores (CACS) that were measured with non-gated chest CT predicted perioperative cardiovascular events in patients who were undergoing lower-risk lung cancer surgery.
Method
In this retrospective single center study, we evaluated 3112 consecutive lung cancer patients with non-gated chest CT before low-medium risk surgeries in 2017. We measured CACS and assessed clinical risk factors according to the revised cardiac risk index (RCRI) scores and predictable surgery factors. Perioperative cardiovascular events were defined as cardiac death, acute coronary syndrome, pulmonary edema, atrial and ventricular arrhythmia with hemodynamic compromise, and complete heart block during hospitalization.
Result
83 patients (2.7%) had perioperative cardiac events, 71 (85.5%) of them were atrial fibrillation. Coronary calcification CT findings were seen in 761 (24.5%) patients. CACS were associated with incidence of cardiac events (p<0.001). In the receiver-operating characteristic (ROC) curve analysis of CACS for prediction of cardiac events, the cutoff value was 1 (sensitivity, 0.60; specificity, 0.75; area under the curve, 0.680). In the multivariate analysis, CACS >1 (OR=1.75, 95% CI: 1.08–2.84, p=0.023), age (OR=1.06, 95% CI: 1.03–1.10, p<0.001), pulmonary function classification (p<0.001) and thoracotomy (OR=3.06, 95% CI: 1.78–5.26, p<0.001) were predictive of cardiovascular complications.
Conclusion
Predicative value of CACS based on non-gated chest CT is high for perioperative cardiovascular risk in lung cancer patients with lower-risk lung surgery. It may be considered as a valuable tool for preoperative risk assessment in these patients without additional testing.

Abstract
Abstract
Background
Platelet endothelial aggregation receptor-1 (PEAR1), expressed in endothelium, platelets, and other tissues, is a platelet transmembrane tyrosine kinase receptor involved in platelet aggregation and platelet-platelet contact. The minor allele (A) in intron 1 of the PEAR1 gene (rs12041331, G>A) is associated with an reduced PEAR1 protein expression and suppressed platelet aggregation response toward multiple agonists. But current evidences on the association between PEAR1 rs12041331 polymorphisms and cardiovascular outcomes in patients with acute coronary syndrome (ACS) and/or percutaneous coronary intervention (PCI) are discordant.
Purpose
To characterize and quantify the association between PEAR1 rs12041331 polymorphisms and cardiovascular outcomes in patients with ACS and/or PCI.
Methods
We conducted a systematic review and meta-analysis by searching MEDLINE via PubMed, EMBASE, Cochrane Central Register of Controlled Trials, SinoMed, CNKI, and Wanfang Data before Dec 7, 2019 to identify studies evaluating the association between PEAR1 rs12041331 polymorphisms and cardiovascular outcomes in patients with ACS and/or PCI. The primary outcome was the major adverse cardiovascular outcomes (MACEs) defined by each study. We adopted the Mantel-Haenszel method to calculate the relative risks (RRs) with 95% confidence intervals (CIs) and the corresponding P values using the random effect model. To assess the effect of ethnicity, we performed the subgroup analyses per ethnic population using the fix effect model.
Results
Among 542 citations identified along with 1 from additional sources, we included 4 studies, which documented 218 MACEs in 8180 patients. The A allele frequency in each study was comparable with that reported in the 1000 Genome Project, but varied among ethnic populations, that is 45.8% in East Asians, 46.5% in American Africans, and 9.2% in Caucasians, adopted from the 1000 Genome Project. A-allele carriers are associated with a 54% increase in MACEs than non-A-carriers (RR, 1.54; 95% CI, 1.10–2.16; P=0.01) with a low but non-significant heterogeneity. Subgroup analyses showed that A-allele carriers tend to have more MACEs than non-A-allele carriers despite of ethnicity, that is 1.32-fold increase in East Asians (RR, 1.32; 95% CI, 0.99–1.77; P=0.06), 2.43-fold in Caucasians (RR, 2.43; 95% CI, 0.99–5.98; P=0.05), and 3.56-fold (RR, 3.56; 95% CI, 1.08–11.70; P=0.04) in American Africans.
Conclusions
Our study indicates that the PEAR1 rs12041331 is prognostic in patients with ACS and/or PCI and treated with DAPT, which might be not caused by the associations with pharmacological response to antiplatelet agents. Further investigations are thus required to address the unrevealing mechanisms of PEAR1, especially on the development of atherosclerosis and the occurrence of acute adverse ischemic events.

Abstract
Abstract
Background
Percutaneous left atrial appendage closure (LAAC) is currently guided by fluoroscopy and transesophageal echocardiography (TEE).
Objective
We report an LAAC technique using intracardiac echocardiography (ICE) and electroanatomic mapping system (EAMS) under local anesthesia without fluoroscopy exposure.
Methods
Seven non-valvular atrial fibrillation (NVAF) patients with high risk of stroke and bleeding (male 5/7, aged 71.7±8.8 years, mean CHA2DS2-VASc score 5.1±2.1; mean HAS-BLED score 3.0±1.2) were enrolled. ICE probe was advanced into left atrium (LA) navigated by the EAMS. LAA sizing and LAmbreTM device implantation were guided by ICE following the orthogonal tri-axial algorithm (Axis-X: from left pulmonary veins [LPVs] to LAA; Axis-Y: from right PV ostium to LAA; Axis-Z: from lower LA to LAA).
Results
There were two cauliflower-like, two chicken-wing-like and three cactus-like LAAs. The mean diameters of ostia and landing zone were 21.4±3.9mm and 20.4±4.2mm, respectively. LAmbre devices with a mean umbrella diameter of 23.7±4.2mm and cover disc diameter of 29.4±3.6mm were successfully implanted and acute complete LAA sealing without peri-device leak (PDL) were achieved in all cases. The mean procedural duration was 73.0±21.4min. No fluoroscopy exposure nor contrast consumption were recorded. No procedure-related complications were documented. The PDL at 45-day follow-up was 1.7±0.8mm. No stroke or thromboembolic events were documented.
Conclusions
The fluoroscopic exposure could be minimized, even to zero, in the ICE-guided LAAC procedures feasibly and safely using LAmbre devices. The orthogonal tri-axial assessment is considered efficacious and safe for the procedures.

Abstract
The 2019 novel coronavirus (2019-nCov) has caused increasing number of infected cases globally. This study was performed to analyze information regarding the transmission route and presence of viral nucleic acids on several clinical samples. Confirmed 2019-nCov-infected cases were identified in Dongyang and were treated according to guidelines for the diagnosis of 2019-nCov infection released by the National Health Commission. Information regarding the contacts that the infected people had was collected to determine whether it caused clustered cases. A series of successive nucleic acid examination of feces, oropharyngeal swabs, and sputum was also performed, and the results were analyzed. A total of 19 confirmed cases of 2019-nCov infection were identified in Dongyang, Zhejiang Province, China. Five cases showed severe symptoms, and the remaining ones showed mild manifestations. Ten cases infected from two asymptomatic individuals were clustered into two groups. Among 14 cases with consecutive nucleic acid test results, four patients showed positive results in feces after their negative conversion in oropharyngeal swabs. Asymptomatic individuals with the virus could cause 2019-nCov clustered cases, and the clustered cases may differ from sporadic cases on age and length of hospitalization. In addition, nucleic acids in feces last longer than those in oropharyngeal swabs.

Abstract
Recently, important regulatory mechanisms of microRNAs (miRNAs) have been widely reported in human cancers including cervical cancer. The purpose of this study is to preliminarily clarify the function of miR-1294 in cervical cancer. The expression of miR-1294 or FLOT1 was detected using RT-qPCR or Western blot analysis. MTT, Transwell and luciferase reporter assays were used to explore the functional mechanism of miR-1294. The results showed that miR-1294 expression was decreased in cervical cancer. Functionally, overexpression of miR-1294 restrained the viability and metastasis of cervical cancer cells. MiR-1294 can also block EMT and suppress β-catenin expression in cervical cancer cells. Additionally, FLOT1 was confirmed to be a direct target of miR-1294. The knockdown of FLOT1 impeded the progression of cervical cancer. More importantly, miR-1294 inhibited the occurrence of cervical cancer by interacting with FLOT1. In conclusion, miR-1294 inhibits cell viability, migration and invasion by suppressing FLOT1 expression.

Abstract
MicroRNAs (miRNAs) have been demonstrated to have promoting or inhibiting effects on the tumorigenesis of multiple cancers, including ovarian cancer (OC), by regulating its downstream target genes. In the presented experiment, our aim was to explore the role of miR-543 in OC cell proliferation and invasion. Results of quantitative reverse transcription-polymerase chain reaction (qRT-PCR) and Western blot revealed that miR-543 have lower expression levels, while Twist homolog 1 (TWIST1) was expressed with higher levels in OC tissues and cells. Furthermore, the effects of abnormal miR-543 expression in OC cell proliferation and invasion were detected by CCK-8 and Transwell assay. According to luciferase reporter assay results, TWIST1 was identified as a downstream target of miR-543 in OC, and a negative correlation was observed between TWIST1 and miR-543 expression by Spearman's correlation analysis in OC tissues. In addition, TWIST1 may reverse the miR-543 suppression effect on OC cell proliferation and invasion. To sum up, miR-543 may promote OC cell proliferation and invasion by targeting TWIST1.

Abstract
Objective: To understand the cognition on and status quo of influenza vaccination among all age groups in the survey areas from 6 provinces so as to explore the main factors related to influenza vaccination. Methods: A cross-sectional survey method was conducted to study the knowledge on influenza prevention and control, as well as on the status of influenza vaccination in Beijing, Inner Mongolia, Shanghai, Guangdong, Yunnan, and Gansu provinces through 12320 health hotline telephone with method of random number table in Mar-May 2018. The survey sample size was 9 438 respondents. Results: The survey response rate was 46.4%(10 045/21 658). A total of 10 045 respondents were surveyed. The awareness on flu-related knowledge "influenza is different from the common cold" was 75.3% (7 564/10 045), rate on "influenza virus will cause serious consequences" was 82.0% (8 241/10 045). The rate of health behavior such as frequent hand, washing hand, wearing masks and isolating themselves were 80.41% (7 936/9 873), 75.8% (7 506/9 899) and 73.6%(7 228/9 822) respectively when the influenza-like symptoms already started. The influenza vaccination rate in the past year was only 5.7% (570/10 037). Multivariate logistic analysis of influenza vaccination rate in the past year showed that respondents who were from Gansu province or Beijing, respondents occupations were as medical staff or full-time students, respondents who were living with more than 2 people at the same house, respondents who had had influenza symptoms without wearing masks, the influenza vaccination rates were higher in the past year. Conclusions: Rates regarding the awareness of influenza-related knowledge, health behavior when the influenza-related symptoms already started and having received the influenza vaccine vaccination in the past year should be further improved in the six provinces. Health education on influenza-related knowledge and vaccine vaccination should be strengthened, strategies including free vaccination are bound to be explored.

Abstract
Objective: To compare the efficacy and safety profiles of tiotropium/olodaterol with the mono-components in Chinese and total study population from TONADO trial. Methods: In the replicate, double-blind, parallel-group, active-controlled, randomized, 52-week, Phase Ⅲ TONADO studies (TONADO 1+2), patients received tiotropium/olodaterol, tiotropium, or olodaterol via the Respimat(®) Inhaler (Boehringer Ingelheim, Germany). Primary end points were forced expiratory volume in 1 second (FEV(1)) area under the curve from 0 to 3 hours (AUC(0-3h)) response and trough FEV(1) response, and St George's respiratory questionnaire (SGRQ) total score at 24 weeks. Adverse events were also collected. This subgroup analysis only focused on the efficacy and safety of the drug at the approved dose in China. Results: 548 Chinese patients were randomized, aged 41 to 82 years [mean age, (63±8) years] and most were male (526, 96%), 111 received tiotropium/olodaterol 5/5 μg, and 127 received tiotropium 5 μg and 95 received olodaterol 5 μg. The baseline characteristics of these groups were similar. After 24 weeks, treatment with tiotropium/olodaterol 5/5 μg, tiotropium 5 μg and olodaterol 5 μg resulted in an adjusted mean FEV(1) AUC(0-3h) response of 0.240, 0.157 and 0.079 L, and trough FEV(1) response of 0.117, 0.068 and-0.001 L, respectively. Tiotropium/olodaterol 5/5 μg significantly improved SGRQ scores in Chinese patients compared with olodaterol 5 μg (32.729 and 37.202, respectively). Generally, the safety profile of tiotropium/olodaterol was comparable with mono-components in 52 weeks. Conclusion: Compared with tiotropium or olodaterol, tiotropium/olodaterol in Chinese patients provided significant improvement in lung function and quality of life, and the safety profiles were similar.

Abstract
Objective: To evaluate the efficacy and prognostic factors in core binding factor (CBF) acute myeloid leukemia (AML) under current therapy modalities, therefore optimizing the treatment strategies. Methods: Standard cytological and immune methods including next generation sequencing (NGS) were used for risk stratification. Complete remission (CR) rate, disease-free survival (DFS) and overall survival (OS) were assessed by multivariate Logistic and Cox regression models in a total of 206 adults (aged 16-65 years) with CBF-AML, including 152 AML patients with t(8;21) and 54 with inv(16). Results: The CR rate of inv(16) patients after first course was 54/54(100%), significantly higher than that of t(8;21) patients [127/147(86.4%), P=0.005]. The fusion transcript level and KIT mutation were independent factors related to CR rate in t(8;21) patients (P=0.044 and 0.027; respectively). DFS and OS in inv(16) patients tended to be more superior than that in t(8;21) patients (P=0.066 for DFS; P=0.306 for OS; respectively). Multivariate Cox identified negative expression of CD(19) and female gender the independent predictors of inferior DFS in t(8;21) patients (P=0.000 for CD(19); P=0.006 for sex; respectively). Analysis of combining CD(19) with gender indicated that females/CD(1)(9-)subpopulation had significantly poor DFS than did males/CD(19)(+) ones (Bonferroni-P<0.000 01). The number of mutations in each patient, FLT3-ITD and additional karyotype abnormalities did not affect CR rate and DFS (all P>0.05). Conclusions: Patients with inv(16) have better induction response than those with t(8;21). High level of fusion transcripts and positive KIT mutation are associated with low CR rate in t(8;21) patients. Negative CD(19) expression and female gender are independent predictors of inferior DFS in t(8;21) patients.
