ABSTRACT

The arachidonic acid (AA) metabolic pathway participates in various physiological processes as well as in the development of malignancies. We analyzed genomic alterations in AA metabolic enzymes in the Cancer Genome Atlas (TCGA) prostate cancer (PCa) dataset and found that the gene encoding soluble epoxide hydrolase (EPHX2) is frequently deleted in PCa. EPHX2 mRNA and protein expression in PCa was examined in multiple datasets by differential gene expression analysis and in a tissue microarray by immunohistochemistry. The expression data were analyzed in conjunction with clinicopathological variables. Both the mRNA and protein expression levels of EPHX2 were significantly decreased in tumors compared with normal prostate tissues and were inversely correlated with the Gleason grade and disease-free survival time. Furthermore, EPHX2 mRNA expression was significantly decreased in metastatic and recurrent PCa compared with localized and primary PCa, respectively. In addition, EPHX2 protein expression correlated negatively with Ki67 expression. In conclusion, EPHX2 deregulation is significantly correlated with the clinical characteristics of PCa progression and may serve as a prognostic marker for PCa.

ABSTRACT

OBJECTIVE@#To compare clinical effects of different postoperative rehabilitation modes on lumbar degenerative diseases, and explore influence of rehabilitation mode and other factors on postoperative effect.@*METHODS@#From June 2013 to July 2016, totally 900 patients were admitted from nine tertiary hospitals in Beijing to perform single segment bone grafting and internal fixation due to lumbar degenerative diseases were prospectively analyzed. There were 428 males and 472 females, the age of patient over 18 years old, with an average of (51.42±12.41) years old;according to patients' subjective wishes and actual residence conditions, all patients were divided into three groups, named as observation group 1 (performed integrated rehabilitation approach and orthopedic treatment model intervention), observation group 2 (performed integrated rehabilitation approach and orthopedic treatment, classified rehabilitation model intervention), and control group(performed routine rehabilitation model intervention). Visual analogue scale(VAS), Oswestry Disability Index(ODI) and Japanese Orthopaedic Association (JOA) were used to evaluate postoperative efficacy among three groups at 24 weeks. Possible factors affecting the postoperative efficacy including age, age grouping, gender, body mass index (BMI), BMI grouping, education level, visiting hospital, payment method of medical expenses, preoperative complications, preoperative JOA score, clinical diagnosis, surgery section, operative method, intraoperative bleeding volume, postoperative complications and rehabilitation mode were listed as independent variables, and postoperative ODI score at 24 weeks as dependent variables. Univariate analysis was used to analyze relationship between influencing factors and postoperative efficacy. Multiple linear regression was used to analyze relationship between influencing factors, rehabilitation mode and postoperative ODI score at 24 weeks, in further to find out the main reasons which affect postoperative efficacy, and to analyze impact of rehabilitation mode on postoperative efficacy.@*RESULTS@#All patients were followed up for 24 weeks after operation. All incisions healed at stage I with stable internal fixation. (1)Evaluation of postoperative efficacy:① There were no statistical differences in preoperative VAS and ODI among three groups(@*CONCLUSION@#Preoperative JOA score, gender, age could predict postoperative clinical effects of lumbar degenerative diseases in varying degrees treated with single level bone graft fusion and internal fixation. Different rehabilitation modes could improve clinical effects. Intergrated rehabilitation orthopedic treatment model and integrated rehabilitation approach and orthopedic treatment with classifiedrehabilitation model are superior to conventional rehabilitation model in improving patients' postoperative function and relieving pain, which is worthy of promoting in clinical.

ABSTRACT

This research was used with high performance liquid chromatography(HPLC), combined with information entropy-response surface method(RSM) to investigate the ethanol concentration, extraction time, liquid-to-material ratio. Taking the content of four chromogens as evaluation indexes, the weight coefficients of each index were given, and the comprehensive score was calculated to optimize the extraction process. Then, prim-O-glucosylcimifugin was used as the reference, the relative calibration factors(RCFs) of cimifugin, 4'-O-β-D-glucosyl-5-O-methylvisamminol and sec-O-glucosylhamaudo to prim-O-glucosylcimifugin were calculated respectively. The contents of four components in Saposhnikoviae Radix were determined by both external standard method(ESM)and quantitative analysis of multi-components by single marker(QAMS) method, and the results were compared. At last, combined with principal component analysis(PCA) and orthogonal partial least squares discriminant analysis(OPLS-DA) to evaluate the quality of the Saposhnikoviae Radix in different production areas. The optimal extraction process parameter of the Saposhnikoviae Radix was as follows: liquid-to-material ratio is 60∶1(mL·g~(-1)), extraction time is 35 min, and ethanol concentration is 70%. The repeatability of the RCFs was perfect, and the results calculated by the QAMS were consistent with the results from the ESM. The stoichiometric results indicate that there are obvious differences in the distribution of Saposhnikoviae Radix in different production areas, and cimifugin and prim-O-glucosylcimifugin are the characteristic compounds that cause this difference. In this study, the optimal extraction process is stable and feasible, and the method of QAMS is accurate and reliable. From the perspective of four chromogens, there are differences in the quality of the Saposhnikoviae Radix in different production areas. Therefore, the established extraction process combined with the method of QAMS can be used to evaluate the quality of Saposhnikoviae Radix and provide a scientific basis for the quality control of Saposhnikoviae Radix.

ABSTRACT

To find the status of outcome indicators reported in published randomized controlled trial(RCT) of traditional Chinese medicine(TCM) for essential hypertension in the past two years, we searched for relevant information from four Chinese databases, three English databases and two clinical trial registries in this study, from January 2018 to September 2019. The outcome indicators of RCT were extracted and categorized from trials and the risk of bias was assessed by ROB tools from the Cochrane Collaboration. A total of 125 RCTs and 15 RCT protocols were finally included after study screening. The results showed that the RCT outcomes mainly included efficacy and safety outcomes. Efficacy indicators mainly included blood pressure measurement, quality of life assessment, blood biochemical indicators, urine analysis, arterial ultrasound, vascular endothelial function indicators, hematocrit, hemorheology indicators and other indicators. The safety indicators mainly included general physical examination items, heart, liver and kidney function tests, blood, urine, and stool routine examinations as well as adverse drug reactions/events. The current RCTs cannot distinguish primary and secondary outcomes, and the RCT protocols didn't report efficacy criteria clearly. They both didn't report health economic indicators and the methodological qualities were relatively low. In view of the current status on outcome indicators reported in TCM RCTs, constructing a core outcome set of TCM for essential hypertension and improving the methodology quality of RCTs will help to accurately reflect the actual efficacy of TCM intervention.

ABSTRACT

To prove that ursolic acid(UA)could activate the autophagy of colorectal cancer HCT116 cells by inhibiting hedgehog signaling pathway. The effect of UA on the viability of HCT116 cells was determined by MTT assay. The effect of UA on the proliferation and migration of HCT116 cells was detected by crystal violet staining and scratch test. In the study on autophagy, the time points were screened out first: the autophagy fluorescence intensity of UA acting on HCT116 at different time points were detected by Cell Meter~(TM) Autophagy Assay Kit; Western blot was used to detect the expression of autophagy protein P62 at different time points. Then, Cell Meter~(TM) Autophagy Assay Kit was used to detect the effect of UA on autophagy fluorescence intensity of HCT116 cells. The effect of different doses of UA on the expressions of LC3Ⅱ and P62 proteins in HCT116 cells were detected by Western blot. Further, AdPlus-mCherry-GFP-LC3 B adenovirus transfection was used to detect the effects of UA on autophagy flux of HCT116 cells; UA combined with autophagy inhibitor chloroquine(CQ) was used to detect the expression of LC3Ⅱ by Western blot. In terms of mechanism, the effect of UA on hedgehog signaling pathway-related proteins in HCT116 cells was detected by Western blot. The results showed that UA inhibited the activity, proliferation and migration of HCT116 cells. UA enhanced the fluorescence intensity of autophagy in HCT116 cells, while promoting the expression of LC3Ⅱ and inhibiting the expression of P62, in a time and dose dependent manner. UA activated the autophagy in HCT116 cells, which manifested that UA resulted in the accumulation of fluorescence spots and strengthened the fluorescence intensity of autophagosomes; compared with UA alone, UA combined with autophagy inhibitor CQ promoted the expression of LC3Ⅱ. UA reduced the expressions of PTCH1, GLI1, SMO, SHH and c-Myc in hedgehog signaling pathway, while increased the expression of Sufu. In conclusion, our study showed that UA activated autophagy in colorectal cancer HCT116 cells, which was related to the mechanism in inhibiting hedgehog signaling pathway activity.

ABSTRACT

Objective:To analyze the clinical characteristics and risk factors of clopidogrel resistance after intracranial arterial stent implantation in patients with ischemic cerebrovascular disease.Methods:Retrospective case-control study was used.A total of 360 patients with ischemic cerebrovascular disease hospitalized in Beijing Tiantan Hospital from January 2017 to December 2018 were selected.All patients received intracranial arterial stenting and received double anti-platelet drugs after operation.Patients were divided into clopidogrel resistance group and non-resistance group according to the inhibition rate of platelet aggregation measured by thromboelastography.Clinical data and laboratory indicators of patients in the two groups were compared using two independent sample T tests and Mann-Whitney U tests, and possible risk factors of clopidogrel resistance were analyzed by Logistic regression.Results:White blood cell (WBC) count, neutrophils count, lymphocyte count, cholesterol, LDL cholesterol, and serum homocysteine levels in the clopidogrel non-resistant group were (6.58±1.45)×10 9/L, (4.01±1.05)×10 9/L, 1.83(1.49, 2.23)×10 9/L, (3.63±0.85) mmol/L, 1.93(1.53, 2.31) mmol/L, and 14.3(11.80, 17.00) μmol/L, respectively.Compared with the clopidogrel non-resistant group, the WBC count, neutrophils count, lymphocyte count, cholesterol, LDL cholesterol and serum homocysteine levels in the clopidogrel resistant group were all higher (7.19±1.53) ×10 9/L, (4.40±1.05) ×10 9/L, 2.03(1.63, 2.58)×10 9/L, (4.02±0.99) mmol/L, 2.04(1.68, 2.78) mmol/L and 15.90(12.25, 22.20) μmol/L, respectively.The difference was statistically significant ( t=3.277, t=2.867, Z=2.457, t=3.409, Z=2.705 and Z=2.220, respectively; P value were 0.001, 0.004, 0.014, 0.001, 0.007 and 0.026, respectively). Logistic regression analysis showed that high serum homocysteine ( OR=1.031, 95% CI 1.006-1.057, P=0.015) was an independent risk factor for clopidogrel resistance. Conclusion:Patients with clopidogrel resistance have high leucocyte, blood lipid, homocysteine and other clinical characteristics.High serum homocysteine is an independent risk factor for clopidogrel resistance.

ABSTRACT

OBJECTIVE@#To investigate the effect of Shexiang Baoxin Pill (, SBP) on early hypertensive renal injury in rats and to explore the possible mechanism.@*METHODS@#Twelve-week-old spontaneous hypertensive rats (SHRs) with high-salt diet (dietary containing 8% NaCl) were randomized into the SBP group [40 mg/(kg·d)], losartan potassium group [20 mg/(kg·d)] and saline group by stratified random sampling method, 12 in each group. Blood pressure and urea albumin creatinine ratio were measured. After 10 weeks, the expression levels of serum creatinine (Scr), hypersensitive C-reactive protein (hs-CRP), interleukin (IL)-1 β, IL-6, tumor necrosis factor α (TNF-α), and transforming growth factor β (TGF-β) in serum were assessed. Kidney pathology periodate-schiff staining was performed. Semi-quantitative count of macrophage infiltration was determined by immunochemistry of CD68 staining. Real-time quantitative polymerase chain reaction and Western blot were performed to examine the mRNA and protein expressions of Toll-like receptor 4 (TLR4), nuclear factor κB (NF-κB), monocyte chemokine peptide (MCP-1), inducible nitric oxide synthase (iNOS), and arginase-1 (Arg-1).@*RESULTS@#SBP did not affect the mortality of SHR (P<0.05). SBP significantly reduced the level of elevated blood pressure of SHRs, but the effect was less significantly than that of losartan potassium. SBP decreased urine protein (P<0.01) and the expression levels of IL-1 β, IL-6, TNF-α, and TGF-β in serum. The 22-week-old SHRs showed mild proliferation of glomerular endothelial cells, glomerular ischemic lesions, inflammatory cell infiltration in renal tubular interstitium and arteriosclerosis. Both SBP and losartan potassium had alleviated renal pathological change, and significantly reduced the infiltration of macrophage (P<0.05, P<0.01). SBP and losartan potassium decreased the expressions of TLR4, NF-κB, MCP-1, iNOS, and Arg-1.@*CONCLUSION@#SBP significantly modified the early hypertensive renal injury by reducing inflammation, and the effect was similar to losartan potassium.

ABSTRACT

Objective: To observe the efficacy and safety of percutaneous mechanical thrombectomy (PMT) in treatment of acute iliofemoral vein thrombi. Methods: PMT using Aspirex catheter was performed in 21 patients of acute iliofemoral vein thrombi after placement of inferior vena cava filter. Angiography was performed to evaluate thrombi clearance after PMT. Patients with residual thrombi were treated with adjunctive catheter directed thrombolysis (CDT) and reexamined with angiography every day. After thrombi removal, balloon dilatation and stent implantation were performed if severe stenosis or occlusion of iliac vein was found. Then inferior vena cava filter was retrieved. The complications of interventional therapy, the effect of thrombi removal and the improvement of symptoms were observed. The patency of deep vein and the Villalta scoring system were evaluated for assessment of the incidence of post-thrombotic syndrome 1, 3 and 6 months after the procedures. Results: All 21 patients were successfully treated with PMT. Eight patients had grade III thrombectomy (complete removal).The other 13 patients had grade Ⅱ thrombectomy (partial removal), and the residual thrombi were cleared with CDT. Balloon dilation and stent placement were performed in 13 patients with severe stenosis or occlusion of left iliac vein. The venous blood flow restored and symptoms of lower limb swelling and pain alleviated in all 21 patients after therapy. There was no death nor serious complication related to the procedures. No thrombosis recurrence was found, and all stents kept patent during the follow-up. One patient with 5 points of Villalta score developed mild post thrombotic syndrome 6 months after procedure. Conclusion: PMT is effective and safe for treatment of acute iliofemoral vein thrombi.

ABSTRACT

BACKGROUND@#Circular RNA ciRS-7 has been reported to be involved in the progression of various cancers. However, ciRS-7 expression and its role in clear cell renal cell carcinoma (ccRCC) progression remains unclear. This study aimed to investigate the effect of ciRS-7 expression on ccRCC and the related signaling pathway.@*METHODS@#ciRS-7 expression was analyzed using quantitative reverse transcription polymerase chain reaction in 87 pairs of ccRCC and matched adjacent normal tissues. The role of ciRS-7 in ccRCC cell proliferation and invasion was determined using the cell counting kit-8 and invasion assays, respectively. Potential mechanisms underlying the role of ciRS-7 in promoting ccRCC progression were explored by Western blotting. The relationship between the expression of ciRS-7 and features of ccRCC was analyzed by the Chi-square test and progression-free survival was determined using a Kaplan-Meier plot.@*RESULTS@#ciRS-7 was overexpressed in ccRCC tissues compared with that in matched adjacent normal tissues. In addition, ciRS-7 up-regulation was closely associated with tumor diameter (P = 0.050), clinical stage (P = 0.009), and distant metastasis (P = 0.007). ciRS-7 knockdown in 786O and 769P cells markedly inhibited their proliferative and invasive abilities. In addition, ciRS-7 inhibition reduced phosphorylated epidermal growth factor receptor (p-EGFR) and phosphorylated serine/threonine kinase (p-Akt) levels.@*CONCLUSIONS@#ciRS-7 up-regulation could promote ccRCC cell proliferation and invasion, which may be related with the EGFR/Akt signaling pathway. ciRS-7 might be a potential ccRCC therapeutic target.

ABSTRACT

Purpose@#Microtubule-associated protein 1 light chain 3B (LC3B) serves as a key component of autophagy,which is associated with the progression of carcinoma. Yet, it is still unclear whetherLC3B is also an independent risk factor for intrahepatic cholangiocarcinoma (ICC). We aimto explore the predictive value of LC3B on prognosis of ICC, and to establish a novel andavailable nomogram to predict relapse-free survival (RFS) and overall survival (OS) for thesepatients after curative-intent hepatectomy. @*Materials and Methods@#From August 2004 to March 2017, 105 ICC patients were eligibly enrolled in the ThirdAffiliated Hospital of Sun Yat-sen University. Preoperative clinical information of enrolledpatients was collected. Expression LC3B in the ICC specimen was detected by immunohistochemistry. @*Results@#The 5-year RFS and OS in this cohort were 15.7% and 29.6%, respectively. On multivariateCox regression analysis, independent risk factors for 5-year OS were cancer antigen 125,microvascular invasion, LC3B expression and lymph node metastasis. Except for the above4 factors, neutrophil/lymphocyte ratio and tumor differentiation were independent factorsfor 5-year RFS. The area under the curve of nomograms for OS and RFS were 0.820 and0.747, respectively. @*Conclusion@#The nomograms based on LC3B can be considered as effective models to predict postoperativesurvival for ICC patients.

ABSTRACT

At present, most of Chinese patent medicines have problems, such as weak scientific basis, unclear clinical value evaluation, etc., which lead to the lack of sufficient evidence for the entry into the essential medicine list, medical insurance catalog and other important health resource allocation tools. This has a negative impact on the development of traditional Chinese medicine. It is urgent to establish a comprehensive evaluation methodology system of Chinese patent medicine in China. There are at least three reasons including producing evidence for clinical rational use scientifically, developing an objective and transparent selecting strategy, eventuating and highlighting its clinical value. The process and method of health technology assessment(HTA) can provide reference for the establishment of comprehensive evaluation method of Chinese patent medicine. However, HTA is rarely carried out in the field of traditional Chinese medicine. The latest domestic and international research showed that HTA combined with multi-criteria decision analysis(MCDA) can increase the transparency of decision-making and improve the quality of decision-making. The combined two formed the EVIDEM framework, which is conducive to drug selection and its clinical use. In this paper, the EVIDEM framework was introduced to establish the methodology framework of the comprehensive clinical evaluation system of Chinese patent medicine. A preliminary research idea has been put forward. In the future, we can establish a set of comprehensive clinical evaluation methods for Chinese patent medicine in cooperation with relevant national drug decision-making departments and management departments. It is believed that such cooperation could promote the full implementation of the re-evaluation for Chinese patent medicine.

ABSTRACT

The efficacy of oral Chinese patent medicine in the treatment of acute cerebral infarction was systematically evaluated by network Meta-analysis. The literature search was conducted in three English databases(Medline, EMbase and Cochrane Library) and four Chinese databases(CNKI, VIP, WanFang and SinoMed) from inception to June 2018, and the randomized controlled trials of acute cerebral infarction were screened out according to the pre-set criteria. Two reviewers independently screened out the literature by using pre-specified eligibility criteria, and assessed the quality of included studies according to the risk of bias tool of Cochrane Handbook 5.1.0. Data analysis was conducted by using Stata 13.0 and WinBUGS 1.4.3 software. Finally, 52 RCT were included, involving 11 kinds of oral Chinese patent medicines. The results of the network Meta-analysis showed that in terms of the total effective rate, the order of efficacy was as follows: Naomaitai Capsules>Xiaoshuan Changrong Capsules>Angong Niuhuang Pills>Yangxue Qingnao Granules>Compound Danshen Dripping Pills>Naoxintong Capsules>Tongxinluo Capsules>Naoxueshu Oral Liquid>Zhuyu Tongmai Capsules>Yinxingye Tablets>Compound Danshen Tablets; in terms of neurological deficit scores, the order of efficacy was: Tongxinluo Capsules>Angong Niuhuang Pills>Compound Danshen Dripping Pills>Xiaoshuan Changrong Capsules>Yangxue Qingnao Granules>Zhuyu Tongmai Capsules>Naoxintong Capsules>Naoxueshu Oral Liquid; in terms of Barthel index score, the order of efficacy was: Xiaoshuan Changrong Capsules>Naomaitai Capsules>Naoxueshu Oral Liquid>Angong Niuhuang Pills>Tongxinluo Capsules>Zhuyu Tongmai Capsules. Although different oral Chinese patent medicines can improve these outcomes, the difference in efficacy ranking was relatively large. Because of the small number and low quality of research literature, the conclusion still needs to be proved by multi-center, large-sample, and double-blind randomized trials.

ABSTRACT

The purpose of this study was to evaluate the selection situation of outcome indexes in randomized controlled trials of traditional Chinese medicine(TCM) in the treatment of acute ischemic stroke and to provide suggestions for future research. In this study, four Chinese databases and three English databases were searched from January 2017 to June 2019. The randomized controlled trials of traditional Chinese medicine in the treatment of ischemic stroke were selected according to the pre-established selection criteria. Cochrane bias risk assessment tool was used to evaluate the quality of the included studies. A total of 20 651 related articles were searched, and 11 662 ones were left after eliminating the repetitions. Finally, 42 articles were included, including 36 articles in Chinese and 6 articles in English, 40 randomized controlled trials and 2 registration schemes of randomized controlled trials. The results showed that the outcome indexes of 42 randomized controlled trials were mainly divided into seven categories, that is clinical outcome index, blood biochemical index, mental state evaluation index, cerebral hemodynamics index, index of evaluating the degree of carotid artery stenosis, safety indicators and other indicators. The blood biochemical index was the one with highest frequency, followed by the clinical outcome index. TCM syndrome score was used as an indicator of curative outcome in 17 studies. After the analysis, it was found that there were many problems in selecting the outcome indexes for the randomized controlled trials of traditional Chinese medicine in the treatment of cerebral apoplexy. For example, the end point index and hard index were rarely selected as the main outcome indicators, and the vast majority of them were intermediate alternative indexes; recognized curative effect could not be obtained; there were too many kinds of outcome indicators and excessive heterogeneity, hindering the promotion of superior treatment measures of traditional Chinese medicine in clinical practice. Therefore, we should draw lessons from the establishment method of the international core index outcome index set, construct the core index outcome index set of traditional Chinese medicine in the treatment of ischemic stroke, and develop the outcome index set which accords with the curative effect characteristics of traditional Chinese medicine treatment mea-sures to solve the problems effectively.

ABSTRACT

BACKGROUND@#Degree of mucosal recovery is an important indicator for evaluating the therapeutic effects of drugs in treatment of inflammatory bowel disease (IBD). Increasing evidences has proved that tight junction (TJ) barrier dysfunction is one of the pathological mechanisms of IBD. The aim of this study was to observe whether enhancement of TJ can decrease colitis recurrence.@*METHODS@#Eighty C57BL/6 mice were randomly divided into four groups including normal group, colitis group, sulfasalazine (SASP) treated group, and traditional Chinese drug salvianolic acid B (Sal B) treated group. Colitis was established in mice by free drinking water containing dextran sulfate sodium, after treatments by SASP and Sal B, recombinant human interleukin-1β (IL-1β) was injected intraperitoneally to induce colitis recurrence.@*RESULTS@#Compared with sham control, cell apoptosis in colitis group was increased from 100.85 ± 3.46% to 162.89 ± 11.45% (P = 0.0038), and TJ dysfunction marker myosin light chain kinase (MLCK) was also significantly increased from 99.70 ± 9.29% to 296.23 ± 30.78% (P = 0.0025). The increased cell apoptosis was reversed by both SASP (125.99 ± 8.45% vs. 162.89 ± 11.45%, P = 0.0059) and Sal B (104.27 ± 6.09% vs. 162.89 ± 11.45%, P = 0.0044). High MLCK expression in colitis group was reversed by Sal B (182.44 ± 89.42% vs. 296.23 ± 30.78%, P = 0.0028) but not influenced by SASP (285.23 ± 41.04% vs. 296.23 ± 30.78%, P > 0.05). The recurrence rate induced by recombinant human IL-1β in Sal B-treated group was significantly lower than that in SASP-treated group.@*CONCLUSIONS@#These results suggested a link between intestinal mucosal barrier dysfunction, especially TJ barrier dysfunction, and colitis recurrence. The TJ barrier dysfunction in remission stage of colitis increased the colitis recurrence. This study might provide potential treatment strategies for IBD recurrence.

ABSTRACT

OBJECTIVE@#To study the clinical efficacy of allo-HSCT on FLT3-ITD positive AML patients.@*METHODS@#The clinical data and curative efficacy of 56 FLT3-ITD AML patients treated with allo-HSCT in our hospital from January 2012 to December 2018 were analyzed and evaluated.@*RESULTS@#Neutrophil implantation was successful for all the patients; The median time of granulocyte hematopoietic reconstruction and megakaryocyte hematopoietic reconstruction was 13 (10-20) d and 15 (9-23) d respectively. The median follow-up time for patients 34.3 (5.6-101.4) months, 41 patients were alive and 15 patients dead at the end of follow-up. The 3 years-OS and -DFS rate was 71.2% and 65.6%, respectively. Univariate analysis showed that the OS rate of patients without aGVDH (81.2±9.4)% was significantly higher than that of patients with aGVDH (55.4±9.1) % (χ=5.309,P<0.05). The OS rate of patients achieved CR after one chemotherapy course before allo-HSCT was (80.2±9.2)%, which was significantly higher than that of patients achieved CR after more chemotherapy courses (χ=4.275,P<0.05). Cox multivariate survival analysis showed that CR after more chemotherapy courses and aGVDH after transplantation were risk factors for OS rate.@*CONCLUSION@#Allo-HSCT can improve the prognosis of FLT3-ITD AML patients. The patients achieved CR after one chemotherapy course before allo-HSCT and patients without aGVDH after allo-HSCT have a better prognosis.

ABSTRACT

Wnt5a is a representative Wnt ligand that regulates multiple cellular functions through the Wnt5a non-classical pathway. Although Wnt5a has been implicated in various pathological conditions, its role in cancer is ambiguous and might involve methyl modifications, distinct mRNA isoforms, as well as different downstream pathways. Therefore, it is an essential factor in cancers' progression (invasion, migration, proliferation, and epithelial-mesenchymal transition), and a potential biomarker for prognosis and treatment.
