Abstract
BACKGROUND Homocysteine (Hcy) has been suggested as an independent risk factor for atherosclerosis. Apolipoprotein M (apoM) is a constituent of the HDL particles. The goal of this study was to examine the serum levels of homocysteine and apoM and to determine whether homocysteine influences apoM synthesis. METHODS Serum levels of apoM and Hcy in 17 hyperhomocysteinemia (HHcy) patients and 19 controls were measured and their correlations were analyzed. Different concentrations of homocysteine (Hcy) and LY294002, a specific phosphoinositide 3- kinase (PI3K) inhibitor, were used to treat HepG2 cells. The mRNA levels were determined by RT-PCR and the apoM protein mass was measured by western blot. RESULTS We found that decreased serum apoM levels corresponded with serum HDL levels in HHcy patients, while the serum apoM levels showed a statistically significant negative correlation with the serum Hcy levels. Moreover, apoM mRNA and protein levels were significantly decreased after the administration of Hcy in HepG2 cells, and this effect could be abolished by addition of LY294002. CONCLUSIONS Present study demonstrates that Hcy downregulates the expression of apoM by mechanisms involving the PI3K signal pathway.

Abstract
目的 探讨高危Ph阴性急性淋巴细胞白血病(Ph−ALL)中微小残留病(MRD)对预后和治疗策略的影响。 方法 回顾性分析2008年1月1日至2017年12月31日收治的初治成人高危Ph−ALL并获得完全缓解(CR)患者的临床资料,通过Cox回归模型和Landmark分析,寻找预后相关因素。 结果 177例患者纳入研究,其中男性99例(56%),中位年龄40(16~65)岁,95例(54%)在第1次完全缓解(CR1)后接受异基因造血干细胞移植(移植组)。多因素分析显示,巩固治疗1个疗程后MRD阴性(HR=0.52,95%CI 0.30~0.89,P=0.017)、诱导化疗4周达到CR(HR=0.43,95%CI 0.24~0.79,P=0.006)是影响患者无病生存(DFS)的有利因素,CR1移植是影响患者DFS(HR=0.13,95%CI 0.08~0.22,P<0.001)和总生存(OS)(HR=0.24,95%CI 0.15~0.41,P<0.001)的共同有利因素。121例患者进入Landmark分析,在巩固治疗1个疗程后MRD阴性的85例患者中进行多因素分析显示,巩固治疗3个疗程后MRD阴性是影响患者DFS(HR=0.18,95%CI 0.05~0.64,P=0.008)和OS(HR=0.14,95%CI 0.04~0.50,P=0.003)的有利因素。在巩固治疗1个疗程和3个疗程后MRD均阴性的患者中,移植组患者3年DFS率有高于化疗组的趋势(75.2%对51.3%,P=0.082),但3年OS率相近(72.7%对68.7%,P=0.992)。巩固治疗1个疗程和3个疗程后MRD至少1次阳性的患者中,移植组的3年DFS率(64.8%对33.3%,P=0.006)和3年OS率(77.0%对33.3%,P=0.028)均显著高于化疗组,与这两个时间点MRD均阴性的移植患者的预后差异无统计学意义(P>0.05)。 结论 在高危成人Ph−ALL患者中,巩固治疗1个疗程后MRD阴性是预后良好的独立影响因素。巩固治疗1个疗程和3个疗程MRD均阴性的患者,接受移植或化疗的生存率相似。移植显著改善了巩固治疗1个疗程和3个疗程后MRD至少一次阳性患者的预后。

Abstract
OBJECTIVE To examine the effect of the integrated schistosomiasis control measures in Hunan Province from 2004 to 2019, so as to provide insights into the development of the schistosomiasis elimination strategy. METHODS The integrated schistosomiasis control measures implemented by the health, agriculture, water resources, forestry, land and resources sectors were retrospectively collected in Hunan Province from 2004 to 2019, and the completion of each measure, cost of control measures, Schistosoma japonicum infections in humans and bovines, and snail status were analyzed each year. An index system for assessing the integrated schistosomiasis control effect was constructed using the Delphi method to calculate the integrated schistosomiasis control effect index. In addition, a cost-effect analysis was performed in terms of the decline in the prevalence of S. japonicum infections in humans and bovines, areas with snails in inner embankments, and areas with infected snails. RESULTS A total of 7 110 926 500 Yuan were invested into the integrated schistosomiasis control program of Hunan Province from 2004 to 2019. During the 16-year period, a total of 277 437.12 hm2 snail habitats received molluscicidal treatments, 6 927 230 person-times given expanded chemotherapy, 2 116 247 bovine-times given expanded chemotherapy, 954 850 harmless toilets built, 290 359 bovines fenced, 136 666 bovines eliminated, 141 905 machines used to replace bovines, 39 048.63 hm2 water lands improved as dry lands, 724.12 km irrigation regions improved, 3 994 300 populations covered with safe water, 191 102.89 hm2 forests planted and 38 535.27 hm2 lands leveled. The prevalence of S. japonicum infections was 4.29% in humans and 4.48% in bovines in Hunan Province in 2004, with 2 449.37 hm2 snail habitats in inner embankments and 3 423.74 hm2 infected snail areas. In 2019, the prevalence of S. japonicum infections reduced to 0 in both humans and bovines, and areas of snail habitats reduced to 540.92 hm2 (77.92% reductions), while the areas with infected snails reduced to 0. The overall integrated schistosomiasis control effect index appeared a tendency towards a rise over years since 2004, and the integrated schistosomiasis control effect index was 97.35 in 2019; the annual mean costs for a 1% reduction in the prevalence of S. japonicum infections in 100 populations and 100 bovines were 70.11 Yuan and 4 204.78 Yuan, and the annual mean costs for a 1% reduction in the snail areas in inner embankments and infected snail areas were 2 010.20 Yuan and 1 298.09 Yuan, respectively. CONCLUSIONS The integrated control measures achieve remarkable effectiveness for schistosomiasis control in Hunan Province, with a remarkable decline in the prevalence of S. japonicum infections in humans and bovines and great shrinking of snail areas in inner embankments and infected snail areas. Adequate fund investment is required to improve the integrated schistosomiasis control measures and consolidate the control achievements.

Abstract
OBJECTIVE To analyze the changes in the endemic situation of schistosomiasis in national surveillance sites of Hunan Province, so as to provide scientific basis for the development of the schistosomiasis elimination programme in the province. METHODS According to the requirements of the National Guidelines for Schistosomiasis Surveillance in China (2014 version), a total of 41 national schistosomiasis surveillance sites were assigned in all disease-endemic counties (districts) across Hunan Province. During the period between 2015 and 2019, Schistosoma japonicum infections were monitored in local residents, mobile populations and livestock, and snail status was monitored. The morbidity due to schistosomiasis and snail status was compared between years. RESULTS The sero-prevalence of S. japonicum infections was 2.57% and 1.56% in local residents and mobile populations in national surveillance sites of Hunan Province from 2015 to 2019, respectively, and the sero-prevalence appeared a tendency towards a decline over years. A higher sero-prevalence rate of S. japonicum infections was seen in men than in women (P < 0.01). During the 5-year study period, the sero-prevalence rate of human S. japonicum infections appeared a tendency towards a decline in the marshland, embankment, inner embankment and hilly types of endemic areas over years. There were 44 and 19 egg -positives detected in local residents and 5 and 1 egg-positives in mobile populations in 2015 and 2016 respectively. A total of 9 346 domestic animals were monitored from 2015 to 2019, and 6 egg-positives were detected in 2015 and 2016 (all were bovine). A total of 0.155 billion m2 settings were surveyed from 2015 to 2019, and the mean density of living snails appeared a tendency towards a decline over years, with a 45.79% reduction in 2019 as compared to 2015. However, no S. japonicum infections were identified in snails during the 5-year period. A total of 1 469 mixed snail samples were detected using loop-mediated isothermal amplification (LAMP), and 6 positive snail samples were identified in 2015 (one sample) and 2017 (5 samples). CONCLUSIONS The overall endemic situation of schistosomiasis appears a tendency towards a decline in Hunan Province, and the prevalence of S. japonicum infections is at a low level in humans and livestock; however, there is still a risk of schistosomiasis transmission. Improvements of health education, intensification of schistosomiasis examinations in mobile populations and reinforcement of the surveillance-response system is required to consolidate the achievements of schistosomiasis control in Hunan Province.

Abstract
OBJECTIVE To analyze the endemic situation of schistosomiasis in Hunan Province in 2019, so as to provide insights into the achievement of transmission interruption of schistosomiasis in the province in 2020. METHODS The data pertaining to Schistosoma japonicum infections in humans and livestock and snail status were captured from Hunan Province in 2019 and analyzed. RESULTS Schistosomiasis was endemic in 281 townships (towns) from 41 counties (districts) of 6 cities in Hunan Province by the end of 2019. A total of 991 900 persons received blood testing in Hunan Province in 2019, and 22 773 were positive for the blood testing, with sero-prevalence of 2.30%. All stool examinations were negative in 22 933 individuals detected. The high sero-prevalence was seen in Nanxian County, Anxiang County and Ziyang District. Currently, there were 5 034 cases with advanced schistosomiasis detected in Hunan Province, and they were predominantly identified in Yuanjiang City, Heshan District and Yueyang County. There were 44 963 bovines fenced in schistosomiasis-endemic villages in Hunan Province in 2019, which were predominantly distributed in Yuanjiang City, Hanshou County and Ziyang District, and no positives were detected in 1 996 bovines receiving blood testing or 20 684 bovines receiving stool examinations. In 2019, there were snail habitats of 1.73 billion m2 found in Hunan Province, which were mainly found in Yuanjiang City, Hanshou County and Yueyang County. CONCLUSIONS The endemic situation of schistosomiasis further decreases in Hunan Province in 2019; however, there is still a risk of schistosomiasis transmission in local areas of the province.

Abstract
Objective: To study the clinicopathological features, diagnosis and differential diagnosis of myeloid sarcoma of the breast. Methods: Ten cases of myeloid sarcoma (MS) and 19 cases of diffuse large B cell lymphoma (DLBCL) of the breast were selected from Peking University People's Hospital from February 2005 to September 2019. The cases were evaluated by microscopy and immunohistochemistry basing on WHO classification (2008 and 2017). Results: For the 10 cases of MS, the mean and median age was 33.8 and 31 years (range 23 to 47 years) respectively. All patients presented with breast masses; six presented with B symptoms (6/10); and LDH level was elevated in four patients. The largest tumor dimension was 1.0 to 5.3 cm (mean 2.7 cm). All 10 patients had history of acute myeloid leukemia (AML), and in one patient, the AML occurred after chemotherapy for hydatidiform mole. One case was classified as M0, four were M2, two were M4 and three were M5. For the AML, all patients received chemotherapy and nine were treated by allogeneic hematopoietic stem cell transplant (allo-HSCT) and the breast masses occurred4 months to 2 years post-transplant. Using Ann Arbor staging, five cases were stage Ⅰ, three were stage Ⅱ, and 2 were stage Ⅳ. The MS was found in the left breast (two cases); right breast (three cases) and both breasts (five cases). Lymphocyte in peripheral blood, B symptom and site of lesion had statistical significance between myeloid sarcoma and DLBCL(P<0.05). The tumor cells were primitive, expressing MPO, CD43, CD117, etc. All ten patients had follow-up information, and the median survival period was 14.4 months (range 1 to 50 months). Seven patients died. The prognosis of patients with MS was worse than DLBCL(P=0.002). Conclusions: The clinical history, pathologic morphology, immunophenotyping and molecular studies are very important for diagnosing MS tumors in the breast, and MS may occur after allo-HSCT for AML. Tumor resection, chemotherapy, radiotherapy and donor lymphocyte infusion are recommended for treatment. The prognosis is poor.

Abstract
Low intrinsic conductivity and large volume expansion seriously restrict the efficient lithium storage performance of metal sulfides. Here, we fabricate a hybrid material of NiS2 nanoparticles/carbon nanohelmets (NiS2/CNHs) to address the above issues. As an anode material in lithium-ion batteries, NiS2/CNHs exhibit excellent cycling stability (490 mA h g-1 after 3000 cycles at 5 A g-1) and rate properties (412 mA h g-1 at 10 A g-1), outperforming other NiS x -based anode materials. These remarkable performances originate from the three-dimensional helmet-like integrated architecture of NiS2/CNHs, which reduces the electrode resistance due to the tight combination between NiS2 and CNHs, provides efficient diffusion paths for the electrolyte and Li+ owing to the amorphous nanoporous carbon structure, and significantly mitigates the aggregation and buffers the large volumetric expansion of NiS2 nanoparticles upon long-term cycling thanks to the open three-dimensional architecture and well-dispersed NiS2 nanoparticles on it.

Abstract
Objective: To compare the cytogenetic and molecular responses, outcomes and severe hematologic toxicity of nilotinib and imatinib as frontline therapy in newly diagnosed patients with chronic myeloid leukemia in chronic phase (CML-CP) . Methods: Newly diagnosed CML-CP patients were consecutively recruited from January 2006 to December 2018 who received nilotinib and imatinib as first-line treatment. Clinical data were retrospectively analyzed. Results: A total of 524 patients were classified into 439 (83.8%) receiving imatinib and 85 (16.2%) receiving nilotinib. Comparing with imatinib group, patients in nilotinib group were much younger (P=0.019) and more with intermediate and high Sokal risks (P<0.001) , WBC ≥100×10(9)/L (P<0.001) , HGB<120 g/L (P<0.001) , blast cells in bone marrow (P=0.026) , splenomegaly (P<0.001) by physical examination at diagnosis, and longer interval from diagnosis to TKI treatment (P=0.003) . With a median TKI duration of 57 (range 3-153) months, the probabilities of complete cytogenetic response (CCyR) (P=0.011) , major molecular response (MMR) (P=0.001) and MR(4.5) (P=0.046) were much higher in nilotinib group than those in imatnib according to each risk group. There is no statistical significance on probabilities of failure free survival (FFS) , progression free survival (PFS) and overall survival (OS) at 6 years between the two groups. Multivariate analyses showed that imatinib was an adverse factor associated with achieving CCyR (OR=0.6, 95% CI 0.5-0.8, P=0.001) , MMR (OR=0.6, 95% CI 0.5-0.9, P=0.032) and MR(4.5) (OR=0.6, 95%CI 0.5-0.9, P=0.032) and poor FFS (OR=1.9, 95%CI 1.0-3.4, P=0.041) . In addition, Sokal score was an independent factor affecting cytogenetic and molecular responses, treatment failure, disease progression and survival. Male, WBC ≥100×10(9)/L or HGB<120 g/L at diagnosis were significantly associated with lower cytogenetic and molecular response rates and/or poor FFS. The severe hematologic adverse events were not associated with different TKIs. Conclusions: Nilotinib reaches to the faster and deeper cytogenetic and molecular responses and significantly improves FFS than imatinib in newly diagnosed patients with CML-CP.

Abstract
OBJECTIVE Diabetic nephropathy (DN), as the most common and serious diabetic microvascular complication, has become the first cause of end-stage renal disease (ESRD) in many countries and regions. However, the pathogenesis of renal fibrosis during the development of DN remains unknown. MATERIALS AND METHODS The expression levels of miR-192 and early growth response factor 1 (Egr1) were determined by quantitative Real-Time Polymerase Chain Reaction (qRT-PCR) and Western blotting in the renal tissues of Otsuka-Long-Evans-Tokushima-Fatty (OLETF) and Long-Evans-Tokushima-Otsuka (LETO) rats. The diabetic kidney environment was simulated by a high-sugar medium. The expression levels of miR-192 and Egr1 were further measured in the HK-2 cell line. Egr1 was verified as a potential target of miR-192 by using bioinformatics analysis and luciferase activity assay. The expression level of Egr1 was determined by overexpressing and knocking down the expression of miR-192. In addition, Western blotting was used to determine changes in Transforming growth factor-beta 1 (TGF-β1) and fibronectin (FN). RESULTS Compared with the kidney tissue of LETO rats, the expression of miR-192 was decreased in OLETF rats, whereas the expression of Egr1 was increased. We found the same phenomenon in the HK-2 cell line cultured in the high-glucose medium. Next, miR-192 can act on Egr1 through 3'-UTR to reduce the expression of Egr1 verified by luciferase assay. In addition, the expression levels of TGF-β1 and FN changed significantly, as the expression level of Egr1 increased or decreased. CONCLUSIONS MiR-192 causes degradation of TGF-β1 and FN through targeting Egr1 and affects the progression of TIF and even DN.

Abstract
Objective: To investigate the characteristic and prognostic significance of leukemia stem cells associated antigens expressions including CD34, CD38, CD123, CD96 and TIM-3 in t (8;21) AML. Methods: Bone marrow samples of 47 t (8;21) AML patients were collected at diagnosis from October 2015 to April 2018 in Peking University Peoples' Hospital, then flow cytometry method was performed to detect the expression frequencies of CD34, CD38, CD123, CD96 and TIM-3 to analyze the relationship between leukemia stem cells associated antigens expressions and relapse. Results: Of 47 t (8;21) AML patients tested, the median percentages of CD34(+)CD38(-), CD34(+) CD38(-)CD123(+), CD34(+)CD38(-) CD96(+) and CD34(+) CD38(-) TIM-3(+) cells among nucleated cells were 2.37%, 0.24%, 0.27% and 0.06%, respectively. All the frequencies of CD34(+)CD38(-), CD34(+)CD38(-)CD123(+), CD34(+)CD38(-)CD96(+) and CD34(+) CD38(-)TIM-3(+) cells had no impact on the achievement of CR after the first course of induction. All higher frequencies of CD34(+)CD38(-), CD34(+)CD38(-)CD123(+), CD34(+)CD38(-)CD96(+) cells were related to higher 2-year CIR rate. Whereas, the frequency of CD34(+) CD38(-) TIM-3(+) cells had no impact on CIR rate. Both high frequency of CD34(+) CD38(-) cells and the high level of minimal residual diseases (patients with <3-log reduction in the RUNX1-RUNX1T1 transcript level after the second consolidation therapy) were independent poor prognostic factors of CIR[P=0.025, HR=6.9 (95%CI 1.3-37.4) ; P=0.031, HR=11.1 (95%CI 1.2-99.2) ]. Conclusion: Different leukemia stem cells associated antigens had distinct prognostic significance in t (8;21) AML. High frequencies of CD34(+) CD38(-), CD34(+) CD38(-) CD123(+) and CD34(+)CD38(-)CD96(+) cells at diagnosis predicted relapse in patients with t (8;21) AML.

Abstract
Lycium barbarum polysaccharides (LBP) are considered to be the major bioactive components of L. barbarum and have been widely used as a well-known traditional Chinese medicine and functional food because of their various biological activities. However, no published research has investigated the use of LBP as a feed additive in broilers. The objective of this study was to evaluate the effects of dietary LBP supplementation on the growth performance, digestive enzyme activities, antioxidant status, and immunity of broiler chickens. A total of 256 one-day-old Arbor Acres male broiler chicks were randomly allotted into 4 groups, with 8 replicates of 8 birds each, and were fed a corn-soybean meal-type basal diet supplemented without (control group) or with 1,000, 2,000, or 4,000 mg/kg LBP for 6 wk. The results showed that compared with the control diet, a significant increase in ADG (P < 0.05) during the grower and overall periods was observed in chickens fed the basal diet supplemented with 2,000 mg/kg LBP, whereas supplementation with 1,000 or 2,000 mg/kg LBP decreased feed-to-gain ratio (P < 0.05) during the starter period. The inclusion of LBP in the broiler diets increased overall amylase, lipase, and protease activities (P < 0.05). Supplementation with increasing levels of dietary LBP increased the activities of superoxide dismutase and glutathione peroxidase but decreased malondialdehyde content in the serum and liver (P < 0.05). Broilers fed with LBP-containing diets exhibited higher serum IgG and IgA concentrations (P < 0.05) than the broilers fed with the control diet. Serum tumor necrosis factor α and IL-4 concentrations were significantly elevated in the group fed 2,000 mg/kg LBP compared with the control group (P < 0.05). Broilers fed diets supplemented with LBP showed linear (P < 0.05) and quadratic (P < 0.05) increases in serum IL-6 and interferon gamma concentrations. The results indicated that dietary LBP supplementation can improve growth performance, digestive enzyme activities, antioxidant capacity, and immune function of broilers. In conclusion, LBP may be used as a promising feed additive for broilers, and a supplementation level of 2,000 mg/kg LBP in the broiler diet is recommended.

Abstract
OBJECTIVE To investigate whether CD31 could regulate paracetamol-induced liver injury, thereby providing a new direction for the prevention and treatment of drug-induced hepatitis. MATERIALS AND METHODS Wild-type (WT) mice were treated with acetaminophen (APAP) (250 mg/kg) or isodose of phosphate-buffered saline (PBS). 1, 3, 6 and 12 h after the treatment, the messenger RNA (mRNA) and protein expression level of CD31 in the liver of mice were determined by Real-time reverse transcription polymerase chain reaction (RT-PCR) and Western blotting, respectively. Once CD31 was confirmed to be involved in APAP-induced liver injury, the acute liver injury model in WT mice and CD31 gene deficient (CD31-/-) mice induced by APAP was established. Serum samples were collected at 8 and 24 h after APAP injection (250 mg/kg), and the activity of serum alanine aminotransferase (ALT) was measured. The liver tissues of mice were isolated and analyzed by hematoxylin and eosin (HE) staining. Meanwhile, mononuclear cells (MNCs) were isolated from the liver tissues of mice. The number of infiltrating macrophages and neutrophils was detected by flow cytometry, and the activation level of these cells was analyzed. The expression levels of proinflammatory cytokines in liver tissues, such as TNF-α, IL-1β, keratinocyte chemoattractant (KC), MCP-1 and IL-6, were determined by RT-PCR. The expression levels of cytokines in serum were detected by enzyme-linked immunosorbent assay (ELISA). Moreover, the protein expression levels of JNK, Caspase-3, and cytochrome P450 2E1 (CYP2E1) in liver tissues were detected by Western blotting. RESULTS After APAP treatment, we found that WT mice were more sensitive to APAP-induced liver injury. The level of ALT in WT mice was significantly higher than that of CD31-/- mice, meanwhile, more necrotic or apoptotic cells were found in WT mice. Results also indicated that the expression levels of inflammatory cytokines, including KC, IL-1β, MCP-1 and IL-6, were significantly higher in WT mice. Meanwhile, the number of infiltrating macrophages and neutrophils in the liver tissues of WT mice were much more than that of CD31-/- mice. CONCLUSIONS APAP-treated CD31-/- mice exhibited less liver injury when compared with WT mice. We also confirmed that CD31 was greatly involved in APAP-induced inflammatory response by promoting hepatic inflammatory and cell apoptosis, which might provide a new strategy for the prevention and treatment of drug-induced hepatitis.

Abstract
We have explored the relations between clinicopathological features and cervical lymph node metastases (LNM) in patients with cN0 squamous cell carcinoma (SCC) of the tongue, and developed and validated a nomogram for predicting the risk of their development. Clinical data on 230 patients with cN0 SCC of the tongue who had had primary extended excision and lymph node dissection of the neck were collected retrospectively. They were divided into a development cohort and a validation cohort in a 4:1 ratio. Logistic regression analysis was used to assess the risk factors of cervical LNM in patients in the development cohort, and a nomogram was established to predict the risk of such nodes. In the validation cohort, the predictive performance and compliance of the model were evaluated using the consistency index (C-index) and calibration curve, and the clinical value was evaluated by decision curve analysis. Of the 230 patients, 60 had cervical LNM, of which 60 were invaded (26%). Analysis of the development cohort showed that the site of the primary lesion, depth of invasion, size of the tumour, and histopathological grade were included in the prediction model, which was validated in the validation cohort. Consistency was high (C-index=0.846), calibration good, and it was clinically valuable. The nomogram could be used to predict the probability of occult cervical LNM before operation in patients with stage cN0 SCC of the tongue. It could also be used as a reference tool for dissection of cervical nodes and a communication tool between the doctor and the patient.

Abstract
Clostridium perfringens is the main cause of sudden death in dogs and currently there is no vaccine to prevent it. In this study, a canine C. perfringens type A strain was used to prepare a vaccine. C. perfringens was inactivated by formaldehyde and adjuvants were added. The safety and immunological characteristics of the inactivated C. perfringens vaccine were evaluated in mice and dogs. The results showed that the C. perfringens vaccine was safe and had immunoprotective activity. The serum antibody titre of immunized mice reached up to 6·25 × 104 . Both single immunization of 4 ml and dual immunizations of 2 ml each provided good immune protection, with five of five immunized dogs surviving. This study also studied a detoxified crude α-toxin extract vaccine. The results showed that a single immunization with 0·5 ml of the detoxified crude α-toxin extract vaccine provided immune protection, with five of five immunized dogs surviving. The inactivated C. perfringens type A vaccine can be used to prevent canine C. perfringens infections. SIGNIFICANCE AND IMPACT OF THE STUDY: Clostridium perfringens is the main cause of sudden death in dogs and currently there is no vaccine to prevent it. In this study, an inactivated canine C. perfringens vaccine and a detoxified crude α-toxin vaccine were prepared. The safety and protective effects of these vaccines were evaluated using mouse and dog models. The vaccines were shown to be safe and to provide immune protection effects that can be used to prevent canine C. perfringens infection.

Abstract
Fibroblast growth factor receptor 2 ( FGFR2) in craniofacial bones mediates osteoprogenitor proliferation, differentiation, and apoptosis. The distortion of proper craniofacial bone growth may cause class II and class III skeletal malocclusion and result in compromised function and aesthetics. Here, we investigated the association between variations in FGFR2 and skeletal malocclusions. First, 895 subjects were included in a 2-stage case-control study with independent populations (stage 1: n = 138 class I, 111 class II, and 81 class III; stage 2: n = 279 class I, 187 class II, and 99 class III). Eight candidate single-nucleotide polymorphisms (SNPs) in FGFR2 were screened and validated. Five SNPs (rs2162540, rs2981578, rs1078806, rs11200014, and rs10736303) were found to be associated with skeletal malocclusions (all P < 0.05). That is, rs2162540 was significantly associated with skeletal class II malocclusion, while others were associated with skeletal class III malocclusion. Electrophoretic mobility shift assay and chromatin immunoprecipitation analysis showed that the common genotypes of rs2981578 and rs10736303 contained the binding sites of RUNX2 and SMAD4. Compared with the common genotypes, the minor genotypes at these 2 SNPs decreased the binding affinity and enhancer effect of RUNX2 and SMAD4, as well the levels of FGFR2 expression. In addition, FGFR2 expression contributed positively to osteogenic differentiation in vitro. Thus, we identified FGFR2 as a skeletal malocclusion risk gene, and FGFR2 polymorphisms regulated its transcriptional expression and then osteogenic differentiation.

Abstract
Oxidative stress (OS) is one of the responsible factors for causing renal diseases. For the treatment or prevention of the renal disease, antioxidants use could be a hopeful therapeutic mediation as they block the oxidative reaction along with inflammatory process. Wogonin (Wog) is a plant flavonoid, a pharmacologically active component of Scutellaria baicalensis Georgi (Huang Qui), which exhibits antioxidant activity. In this investigation, we explored the nephroprotective activity of Wog on cadmium (Cd)-induced nephron toxicity in rats. Administering (10 and 20 mg/kg) intraperitoneally diminished Cd-induced anomalies in kidney histology and creatinine and serum urea levels. Wog therapy reduced the Cd-influenced generation of inflammatory mediators, inclusive of tumor necrosis factor alpha, interleukin 6, and interleukin 1 beta. Western blot analysis demonstrated that Wog abolished proinflammatory nuclear factor-kappa B (NF-κB) p65 stimulation, phosphorylation of p38 mitogen-activated protein kinases (MAPKs). In all, Wog demonstrated antioxidative and anti-inflammatory effects in Cd- intoxicated rats by obstructing OS and activation of NF-κB via restricting the stimulation of upstream kinases inclusive of MAPKs.

Abstract
Objective: To compare the clinical features between the 2 cohorts developing myelodysplastic syndrome or acute myeIogenous Ieukemia in Philadelphia chromosome-negative cells (Ph(-) MDS/AML) and maintaining disease stable in the patients with Philadelphia chromosome-positive chronic myeloid Ieukemia (Ph(+) CML) who had clonal chromosomal abnormalities in Philadelphia chromosome-negative metaphases (CCA/Ph(-)) during tyrosine kinase inhibtor (TKI) - therapy. Methods: We retrospectively analyzed Ph(+) CML patients who developed CCA/Ph(-) during TKI-therapy from May 2001 to December 2017. Results: Data of CCA/Ph(-) 63 patients, including 7 progressing to Ph(-) MDS/AML and 56 remaining disease stable were collected. Compared with those with stable disease, patients with Ph(-)MDS/AML had lower hemoglobin (P=0.007) and platelet (P=0.006) counts, and higher proportion of peripheral blasts (P<0.001) when the first time CCA/Ph(-) was detected, and more mosonomy 7 abnormality (5/7, 71.4%) when MDS or AML was diagnosed; meanwhile, trisomy 8 (32/56, 57.1%) was more common in those with stable disease. Outcome of the patients with Ph(-) MDS/AML were poor. However, most of those with CCA/Ph(-) and stable disease had optimal response on TKI-therapy. Conclusions: A few patients with Ph(+) CML developed CCA/Ph(-) during TKI-therapy, most of them had stable disease, but very few patients developed Ph(-) MDS/AML with more common occurrence of monosomy 7 or unknown cytopenia. Our data suggested the significance of monitoring of peripheral blood smear, bone marrow morphology and cytogenetic analysis once monosomy 7 or unknown cytopenia occurred.

Abstract
Objective: To investigate the efficacy and prognostic factors of induction therapy in FLT3-ITD(+) acute myeloid leukemia (AML) in the real world data. Methods: From January 2013 to December 2016, 114 de novo patients with FLT3-ITD(+)AML were enrolled in this study. Out of 114 cases, 75 were male, and 39 were female. The median age was 42 years old (ranged from 14 to 72 years old) . The chemotherapy regimens were used for induction therapy and all cases were followed up. The treatment response was evaluated by MICM and the comparison of the ratio were analyzed by chi-square test and the survival was estimated by Kaplan-Meier analysis and Cox proportional hazards model was used to identify independent prognostic factors. Results: There were 52 FLT3-ITD(+)AML patients with favorable prognosis genes (46 cases with NPM1, 5 cases with RUNX1-RUNX1T1, 1 case with CEBPA double mutation) and 62 patients with other types of FLT3-ITD(+)AML at diagnosis. All patients completed at least one cycle of induction therapy and the clinical curative effect was evaluated, complete remission (CR) rate was 50.0% (57/114) in one cycle and total CR rate was 72.5% (74/104) in two cycles. The CR rate of the FLT3-ITD(+) AML patients with favorable prognosis genes was 67.3% (35/52) in one cycle and 83.3% (40/48) in two cycles; for the other types FLT3-ITD(+)AML patients, the CR rate was 35.5% (22/62) in one cycle and 64.8% (35/54) in two cycles. There was a significant difference in CR rate between the FLT3-ITD(+)AML patients with and without favorable prognosis genes (P<0.05) . This indicates that the FLT3-ITD(+)AML patients with favorable prognosis gene had relatively good therapeutic effect. Among other types of FLT3-ITD(+)AML patients who did not achieve remission from one cycle of chemotherapy, 9 patients were given sorafenib plus chemotherapy and 6 cases (66.7%) achieved CR; 23 patients were given conventional chemotherapy and 7 cases (30.4%) achieved CR. There was a significant difference between sorafenib plus chemotherapy and conventional chemotherapy groups (χ(2)=4.47, P<0.05) and this indicates that sorafenib plus chemotherapy can significantly improve the CR rate of FLT3-ITD(+)AML patients. Comparing overall survival (OS) and disease free survival (DFS) , there was no significant difference between sorafenib plus chemotherapy and conventional chemotherapy groups (P values were 0.641 and 0.517, respectively) . Conclusion: The overall prognosis of FLT3-ITD(+)AML patients is poor, and the stratification therapeutic efficacy of FLT3-ITD(+)AML without favorable prognosis gene can be improved by sorafenib combined with chemotherapy.

Abstract
The study aimed to identify the pivotal genes and pathways involved in prostate cancer metastasis. Using the expression profile dataset GSE7930, downloaded from the Gene Expression Omnibus (GEO) database, differentially expressed genes (DEGs) between primary and highly metastatic prostate cell samples were screened, followed by functional analysis and tumor associated genes (TAG) screening. Protein-protein interaction (PPI) network of DEGs was constructed and module analysis was performed. The expression of DEGs and pathway related genes were evaluated by PCR analysis and the migra- tion ability of prostate tumor cells was observed after FABP4-siRNA blocking. Upregulated FABP4 and GK were signifi- cantly enriched in the PPAR signaling pathway, whereas downregulated IGFBP3 and THBS1 were involved in p53 signaling pathway. Among the identified DEGs, 4 downregulated genes (IGFBP3, NPP4B, THBS1, and PCDH1) and 2 upregulated genes (GJA1 and TUSC3) were TAGs. The module was associated with focal adhesion, ECM-receptor interaction, p53 signaling, and gap junction pathways with the hub node GJA1. After FABP4 silencing by siRNAs in LNcap and metastatic DU-145 cells, the numbers of migrated cells were all significantly declined. The expressions of IGFBP3, TP53 and PPAR were significantly lower in DU-145 cells than in LNcap cells. In conclusion, FABP4, IGFBP3, THBS1, and GJA1 were determined to be potential markers of prostate cancer cell metastasis, and P53, PPAR and gap junction pathways were found to play important roles in prostate cancer cell metastasis. This study may provide helpful guidelines for clinical management.

Abstract
<sec> <title>SETTING</title> The proportion of bacteriologically confirmed tuberculosis (TB) in China has decreased far below the worldwide average. </sec> <sec> <title>OBJECTIVE</title> To investigate whether stepwise measures to ensure sputum quality can improve the rate of bacteriologically confirmed TB. </sec> <sec> <title>DESIGN</title> We enrolled 980 adults with suspected TB from three counties in China during 2017 for this multicentre randomised controlled trial. Half the participants (n = 490) were randomly assigned to intervention groups that received instructions by a study nurse, and sputum induction, if necessary. In the remaining 490 patients, sputum samples were collected without observation. The primary outcome was the proportion of patients detected as bacteriologically positive on smear, culture or molecular assays (EasyNAT or Xpert). </sec> <sec> <title>RESULTS</title> Bacteriological confirmation rates were significantly higher in the intervention than in the control group: overall (159/490 [32%] vs. 122/490 [25%]; P = 0.009); confirmation using smear (17% vs. 11%; P = 0.010); confirmation using culture (28% vs. 21%; P = 0.021); and confirmation using molecular assays (27% vs. 18%; P = 0.001). Most of the improvement was in patients who received instruction alone, while improvement was greatest in younger patients (adjusted odds ratio 1.27, 95%CI 1.05-1.53 per 10 years). </sec> <sec> <title>CONCLUSIONS</title> If implemented effectively in resource-limited primary care clinics, our simple stepwise procedure combining instruction and sputum induction could increase the proportion of bacteriologically confirmed TB significantly. </sec>.

Abstract
We report simple and compact all-fiber erbium-doped soliton and dispersion-managed soliton femtosecond lasers mode-locked by the MXene Ti3C2Tx. A saturable absorber device fabricated by optical deposition of Ti3C2Tx onto a microfiber exhibits strong saturable absorption properties, with a modulation depth of 11.3%. The oscillator operating in the soliton regime produces 597.8 fs-pulses with 5.21 nm of bandwidth, while the cavity with weak normal dispersion (~0.008 ps2) delivers 104 fs pulses with 42.5 nm of bandwidth. Our results contribute to the growing body of work studying the nonlinear optical properties of MXene that underpin new opportunities for ultrafast photonic technology.

Abstract
目的 探讨非老年成人初发急性髓系白血病(AML)患者年龄相关的临床特征、早期治疗反应和预后。 方法 回顾性分析2008年1月至2017年12月收治的18~65岁初发AML(非急性早幼粒细胞白血病)连续病例,分析不同年龄组患者初诊时疾病特征、早期治疗反应、复发和生存,以及相关影响因素。 结果 共收集1 097例患者,男性591例(53.9%),中位年龄42岁。随着年龄的增长,患者WBC显著下降(P=0.003),PLT显著上升(P=0.034),骨髓原始细胞比例显著下降(P=0.021)。SWOG危险度在各年龄组的分布差异无统计学意义(P=0.063)。NPM1阳性伴FLT3-ITD阴性的患者比例随年龄增长显著上升(P<0.001)。多因素分析显示,在总人群中,年龄增加是获得形态学无白血病状态(MLFS)(P=0.053)、完全缓解(CR)(P=0.004)和总生存(OS)(P=0.070)的不利影响因素,但在接受标准诱导治疗的患者中,年龄增加仅与CR相关(P=0.075),而与MLFS和OS无关。 结论 非老年初发AML患者的临床、细胞遗传学和分子学特征随年龄变化而不同。在接受标准诱导治疗的患者中,年龄增加与获得MLFS和OS均无显著相关性。

Abstract
Objective: To analyze the de novo point mutations in known genes among patients with unexplained intellectual disability (ID) or developmental retardation (DD). Methods: A total of 120 outpatients with ID or DD were recruited in the Department of Neurology, Affiliated Children's Hospital of Capital Institute of Pediatrics between September 2015 and April 2017. Target gene sequencing was used to screen the candidate gene. The sequencing data were analyzed by a variety of bioinformatics software. Combining with the phenotypes of the patients, the candidate genetic/genomic variants were identified from next-generation sequencing data. The final pathogenicity of the genetic/genomic variants were interpreted according to the guideline of the American College of Medical Genetics and Genomics (ACMG) for variants after segregation analysis in the parents and necessary family members by Sanger sequencing. The comprehensive physiological function and signaling pathways of 20 disease genes with de novo point mutation discovery was also studied. Results: Among the 120 patients, 23 patients were found to carry clear pathological changes, and the incidence of de novo point variation was 19.2%. The patients included 12 males and 11 females, with an age of 2 months to 6-year-6-month. Five patients were diagnosed with early onset of epileptic encephalopathy. Seven had mental retardation type 5, 6, 8, 19, 20, 22, 39, respectively. Weill-Marchesani syndrome type 2 was found in one case, Wiedemann-Steiner syndrome in one case, Coffin-Siris syndrome in two cases, Rubinstein-Taybi syndrome in one case, GLUT1 deficiency syndrome in one case, Rett syndrome in one case, cardio-facio-cutaneous syndrome 3 in one case, neurodegeneration with brain iron accumulation in one case, corpus callosum local dysplasia in one case, and congenital fibrosis of the extra-ocular muscles in one case. A total of 20 novel mutations were reported in this study. No somatic mutation was found in the samples of 6 patients with mutation and their parents' peripheral blood DNA samples by amplicon-based deep sequencing. This study found that the main disease genes were involved in chromatin remodeling, transcriptional regulation, autophagy body assembly, MAPK signal pathway, DNA methylation, potassium, sodium ion transport, cell skeleton assembly and skeletal muscle development. These genes were significantly enriched in the following biological processes: Ras signaling pathways, transcription factor binding and cancer related signaling pathway. Conclusions: The etiology of children affected with intellectual disability or developmental delay is complex. Harmful de novo point mutation plays an important role in these diseases. Targeted exome/genome sequencing based on the core family is helpful for the molecular diagnosis of patients and the discovery of more genes.

Abstract
Objective: To analyze the clinical characteristics of hereditary coagulation factor Ⅴ deficiency (FⅤD) and to improve the diagnosis and treatment ability of hereditary FⅤD. Methods: A total of 17 patients with hereditary FⅤD admitted to the Department of Hematology, Peking University People's Hospital from February 2013 to January 2018 were selected, and their clinical characteristics, laboratory examination, treatment and prognosis were retrospectively analyzed. Results: There were 9 males and 8 females patients with FⅤD, the median age was 36 (1-72 ) years. The median age of men was 39 (1-72)years, and the median age of women was 33 (8-56)years. There was no significant difference between them (P=0.793). The median prothrombin time(PT) and activated partial thromboplastin time(APTT) values were 21.0(13.0-39.6) s and 54.6(38.2-121.2) s, and the median level of plasma FⅤ was 8.2% (0.9%-39%). Thirteen cases (13/17) were mild, 3 cases (3/17) were moderate, and only 1 case (1/17) was severe according to the FⅤ level. Five cases (5/17) had bleeding, including 3 cases with skin ecchymosis, 1 case with vaginal bleeding, and 1 case with gastrointestinal bleeding. According to the severity of bleeding, 1 case (1/17) had severe bleeding, and the other 4 cases (4/17) were mild bleeding. Conclusions: Patients with hereditary FⅤD either have or do not have bleeding symptoms, with prolonged PT and APTT and decreased plasma of FⅤ activity. There is no need for treatment for those without bleeding symptoms. Fresh frozen plasma is the first choice for patients who have bleeding, and the overall prognosis is good.

Abstract
Objective: To explore the incidence and severity of hepatic adverse events (AEs) and identify factors associated with hepatic AEs in patients with chronic myeloid leukemia (CML) in chronic phase (CP) treated with tyrosine kinase inhibitors (TKIs). Methods: Liver biochemistry parameters [including ALT(alanine aminotransferase), AST(aspartate aminotransferase), ALP(alkaline phosphatase), and TBil(total bilirubin)] during the first 6 months on imatinib (Gleevec(®)), dasatinib (Sprycel(®)) or nilotinib (Tasigna(®)) in CML-CP patients were collected and analyzed retrospectively. Results: A total of 436 patients were enrolled in this study, including 271 with imatinib, 58 with dasatinib, and 107 with nilotinib. The incidences of any abnormality of liver injury were 21.8%(59/271), 15.5%(9/58) and 32.7%(35/107) in the imatinib, dasatinib and nilotinib groups, respectively. Most of the hepatic AEs were CTCAE grade 1 or 2 and mild or moderate liver injury except 1.9% of TBil CTCAE grade 3 in the nilotinib group. Multivariate analyses showed nilotinib [OR=2.9(1.3-6.6), P=0.012; OR=4.4(1.2-15.6), P=0.023] and male gender [OR=2.3(1.4-3.9), P=0.002; OR=3.0(1.2-7.6), P=0.018] were significantly associated with moderate liver impairment. Conclusions: TKIs including imatinib, dasatinib and nilotinib were well tolerated with mild to moderate hepatic AEs in CML-CP patients. Nilotinib and male sex were associated with occurrence of liver biochemistry abnormalities and moderate hepatic injury.

Abstract
Objectives: To explore the comorbidity profile and its impact on reported outcome of patients with chronic myeloid leukemia in chronic phase (CML-CP) receiving tyrosine kinase-inhibitor (TKI) therapy in China. Methods: From September 2015 to March 2016, anonymous questionnaires were distributed to adult CML patients who were receiving TKI treatment in China. The questionnaires included demographics, comorbidity(ies), TKI(s) therapy, annual out-of-pocket expense for TKIs, treatment responses, health-related quality of life (HRQoL) measured by the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36), satisfaction with therapy, impact of TKI therapy on work and daily life. Results: Data from 1 108 respondents in CML-CP were analyzed, 701 (63.6%) were male, median age was 42 years (range, 18-88 years), 76.4% were currently on imatinib, median TKI-therapy-duration was 29 months (range, 3-178 months). Of them, 300 (27.1%) had ≥1 comorbidity(ies), including hypertension(30.3%), diabetes (21.0%), coronary heart disease (12.3%), gastro-intestinal disease (12.3%), liver disease (11.7%), kidney disease (8.3%), cerebrovascular disease (6.7%) and lung diseases (5.7%), thrombosis (1.3%), other benign diseases (15.3%) and other cancer (8.0%), and 74 (24.7%) had ≥2 comorbidities. Multivariate analyses showed the comorbidity profile of other benign diseases was significantly associated with lower HRQoL score and TKI therapy affecting work and daily life, but it did not significantly affect patients' satisfaction with TKI treatment. Female and no complete cytogenetic response (CCyR) were associated with lower HRQoL score, education level ≥bachelor degree and TKI-therapy duration ≥3 years were associated with higher HRQoL score. Switching between first and second generation TKIs and no CCyR were associated with dis-satisfaction or extreme dis-satisfaction with TKI therapy, free out-of-pocket expense for TKI was associated with better satisfaction. Age<60 years and no CCyR were associated with TKI therapy affecting work and daily life. Conclusions: The survey showed that 27.1% Chinese adult patients with CML-CP receiving TKI-therapy had comorbidity(ies). Different comorbidity profile had different impact on patients' HRQoL and different impact of TKI therapy on work and daily life.

Abstract
目的 探讨NPM1突变阳性急性髓系白血病(AML)患者化疗后早期微小残留病(MRD)水平与预后的关系。 方法 回顾性分析137例初治成人伴NPM1基因主要突变(A、B、D突变)AML患者的治疗结果,以及化疗后早期时间点MRD(NPM1突变转录本)水平对预后的影响。 结果 在137例患者中,男67例(48.9%),中位年龄49(16~67)岁,染色体正常核型107例(78.1%),FLT3-ITD突变阳性57例(41.6%),初诊时NPM1基因突变转录本中位水平84.1%(4.1%~509.9%)。在134例可评估的患者中,115例(85.8%)最终获完全缓解(CR)。多因素分析显示,WBC<100×109/L(OR=0.3,95% CI 0.1~0.9,P=0.027)和初始诱导治疗为“IA10”方案(OR=0.3,95% CI 0.1~0.8,P=0.015)是获得CR的有利因素。在108例可评估的CR患者中,存活患者中位随访24(2~91)个月,3年无病生存(DFS)和总生存(OS)率分别为48.0%和63.9%。多因素分析显示,FLT3-ITD突变阳性(HR=3.2,95% CI 1.6~6.7,P=0.002)、巩固治疗2个疗程后MRD高水平(NPM1突变转录本水平较治疗前下降<3个对数级,HR=23.2,95% CI 7.0~76.6,P<0.001)、未接受异基因造血干细胞移植(allo-HSCT)(HR=2.6,95% CI 1.0~6.6,P=0.045)是影响患者DFS的不利因素;MRD在首次获得CR时高水平(NPM1突变转录本水平下降<2个对数级,HR=2.5,95% CI 1.0~6.1,P=0.040)和巩固治疗2个疗程后高水平(HR=4.5,95% CI 2.0~10.3,P<0.001)是影响患者OS的不利因素。进一步分析78例接受化疗(或自体移植)的CR患者,3年DFS和OS率分别为39.7%和59.1%,FLT3-ITD突变阳性和巩固治疗2个疗程后MRD高水平是独立影响患者DFS(HR=3.5,95% CI 1.6~7.6,P=0.002和HR=8.9,95% CI 3.8~20.7,P<0.001)和OS(HR=2.7,95% CI 1.1~6.9,P=0.036和HR=3.1,95% CI 1.2~8.0,P=0.021)的共同不利因素,此外,首次获得CR时MRD高水平(HR=3.1,95% CI 1.2~8.0,P=0.022)也是影响患者OS的不利因素。 结论 在NPM1突变阳性AML患者中,伴有FLT3-ITD突变和化疗后早期MRD高水平预示不良预后。

Abstract
Objective: To explore outcomes in adult with de novo acute myeloid leukemia (AML) received IA10 (10 mg/m(2) d1-3 idarubicin plus cytarabine 100 mg/m(2) d1-7) regimen as induction chemotherapy. Methods: From January 2008 to February 2016, data of consecutive newly-diagnosed AML (non-M(3)) adults treated with IA10 who achieved morphologic leukemia-free state (MLFS) but not accepted allogeneic hematopoietic stem cell transplantation (allo-HSCT) were assessed retrospectively. Results: A total of 198 patients were included in this study with 96 (48.5%) male and a median age of 42 years old (range, 18-62 years old). Using the SWOG cytogenetic classification, 45 (22.7%), 104 (52.5%), 24 (12.1%) and 25 (12.6%) patients belonged to favorable, intermediate, unfavorable and unknown categories, respectively. 6 (3.0%) patients had monosomal karyotype, and 28 (14.1%) positive FLT3-ITD mutation. A complete remission (CR, defined as MLFS with ANC ≥ 1×10(9)/L and PLT ≥ 100×10(9)/L) achieved in 168 (84.8%) patients, a CRp (defined as MLFS with incomplete PLT recovery) in 16 (8.1%) and a CRi (defined as MLFS with incomplete ANC and PLT recovery) in 14 (7.1%). With a median follow-up period of 15 months (range, 1 to 70 months) in survivors, the probabilities of cumulative incident of relapse (CIR), disease free survival (DFS) and overall survival (OS) rates at 2-year were 45.2%, 46.9% and 62.9%, respectively; the median durations of relapse, DFS and OS were 34, 20 and 37 months respectively. At the time of achieving first MLFS, multivariate analyses showed that positive FLT3-ITD mutation and CRi were common adverse factors affecting CIR, DFS and OS; unfavorable-risk of SWOG criteria was an adverse factor affecting CIR and DFS; monosomal karyotype was associated with shorter OS. After first consolidation therapy, FLT3-ITD mutation positive and unfavorable-risk of SWOG criteria had negatively impact on CIR, DFS and OS; peripheral blasts ≥ 0.50 and positive MRD (defined as RQ-PCR WT1 mRNA ≥ 0.6% or any level of abnormal blast population detected by flow cytometry) after first consolidation therapy were common adverse factors affecting CIR and DFS; CRi was an adverse factor affecting DFS and OS. Conclusions: In adult with de novo AML received IA10 regimen as induction regimen, unfavorable molecular markers or cytogenetics at diagnosis and CRi independently predicted poor outcome. In addition, a higher percentage of peripheral blasts, monosomal karyotype and positive MRD after first consolidation therapy had negatively impact on outcomes.
