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.

Abstract
OBJECTIVE To investigate the clinical biological characteristics of EVI1 positive acute myeloid leukemia (AML) and its effect on early chemotherapy. METHODS The clinical and biological cha-racteristics of 33 AML patients with EVI1 positive were retrospectively analyzed in 361 AML patients who were diagnosed and treated in our institute from March 2015 to July 2016, and the clinical and biological features, and rates of the induced remission were compared between the intermediate risk and poor risk with EVI1 positive AML, moreover, the influential factors on complete remission (CR) were analyzed. The expression of EVI1/ABL was tested in 32 healthy donors to confirm the abnormal threshold of EVI1 expression. RESULTS The definition of EVI1 positive was that the quantitative expression of EVI1/ABL was more than 8.0%. The 33 AML patients with EVI1 positive were found in 361 newly diagnosed AML patients, in which the female and male patients were 17 and 16 respectively, the median age was 45 (18-67) years, with a median follow-up of 6.6 (0.7-13.2) months. Intermediate karyotype was found in 17 patients(including 9 patients with normal karyotypes,1 patient with +8);unfavorable karyotype was found in 14 patients [including 7 patients with -7/7q-,4 patients with t (v;11q23),3 patients with inv(3)/t(3;3), and 2 patients without mitotic figures]. The rate of CR in the first induction chemotherapy was 42.4%, and the rate of total CR was 60.6%. According to the NCCN, 16 intermediate risk patients and poor risk patients were divided, without favorable risk patients. The rate of CR in the first induction chemotherapy were 68.8% and 17.6% (P=0.005) in the intermediate risk and poor risk respectively, that of total CR were 81.3% and 41.2%(P=0.032), and the rates of relapse were 7.7% and 14.3%.Univariable analysis revealed that unfavorable karyotype could affect the rate of CR in the first reduction chemotherapy and that of total CR (P=0.004, 0.029). The poor risk patients had higher mortality (41.2% vs. 6.3%, P=0.039) and lower overall survival (OS)(P=0.012). CONCLUSION EVI1 may be not an independent prognostic factor for the AML patients considering the appea-rance in the intermediate and poor risk patients. It predicts poor outcome in the EVI1 positive AML patients who have unfavorable karyocytes, such as -7/7q-, t(v;11q23), and inv(3)/t(3;3), and also a low rate of both CR in the first induction chemotherapy and total CR. It also has a low rate of long-term survival and high mortality in the AML patients with EVI1 positive, who may benefit from allogeneic bone marrow transplantation as soon as possible.

Abstract
Objective: To compare the cytogenetic response detected by conventional banding analysis (CBA) and fluorescence in situ hybridization (FISH) and to explore the correlation between the cytogenetic and molecular response in chronic myeloid leukemia (CML) patients during tyrosine kinase inhibitor (TKI) treatment. Methods: CBA, FISH and real-time quantitative reverse transcriptase polymerase chain reaction (RQ-PCR) methods were performed to detect the cytogenetic and molecular response simultaneously in 504 bone marrow samples from 367 CML patients who received TKI treatment. Results: Among 504 samples, 344 were detected to reach complete cytogenetic response (CCyR) by CBA, while 297 samples reached CCyR by FISH which were considered to carry BCR-ABL positive cells<1%. When the results of CBA, FISH and RQ-PCR were compared in 493 samples at the same time, it showed that in 337 samples with CBA-CCyR, 273 (81.0%) reached FISH-CCyR and 289 (85.8%) were BCR-ABL(IS) (International Scale, IS) ≤1% by RQ-PCR, compared to 9.0 (261/290) were BCR-ABL(IS) ≤1% among 290 samples with FISH-CCyR. There was no significant difference in the median value of BCR-ABL(IS) between samples in CBA-CCyR and FISH-CCyR (0.21% vs 0.13%, z=-1.875, P=0.061) . Furthermore, when the samples were divided into three groups according to BCR-ABL positive cells (0,>0~<1%, 1%~5%) by FISH, the statistical difference was observed, the proportion of samples with BCR-ABL(IS) ≤1% in the three groups were 94.1%, 57.6% and 27.7% respectively (χ(2)=43.499, P<0.001; χ(2)=9.734, P=0.003) , while the median value of BCR-ABL(IS) were 0.10%, 0.64% and 1.80% respectively (z=-5.864, P<0.001; z=-4.787, P<0.001) . Conclusion: FISH results were in good concordance with CBA in identify samples in CCyR, FISH was more sensitive and had better correlation with RQ-PCR results than CBA, but how to define FISH-CCyR need further study.

Abstract
Developing efficient catalysts for the oxygen reduction reaction (ORR) to reduce cathode Pt loading without sacrificing the performance has been under intensive research. Herein, by using density functional theory calculations, the activity and stability of a Pt monolayer supported on Pd3Al(111) as the ORR catalyst have been systematically studied. The simulations demonstrate that due to alloying, the ORR intermediates bind weakly on Pt/Pd3Al(111) with optimal adsorption energy of O and OH. By considering the elemental ORR steps, the ORR mechanism is predicted to be an OOH dissociation mechanism. The rate determining step is OOH dissociation with a reaction barrier of 0.37 eV, lower than the corresponding value on Pt/Pt3Al(111) and Pt(111), indicating the superior activity of Pt/Pd3Al(111). Even considering the unfeasible H adsorption under high potential, the ORR mechanism on Pt/Pd3Al(111) would proceed via O2 hydration, OOH hydration, H2O formation, and H2O desorption, indicating a good ORR electrocatalyst. Furthermore, stability was evaluated by calculating the alloy formation energy and the electrochemical potential shift of surface Pt dissolution. The exceptionally negative alloy formation energy of Pd3Al and the positive dissolution potential shift of the surface Pt atoms show the enhanced durability of Pt/Pd3Al(111). The improved activity, in combination with its enhanced stability, makes the novel ternary alloy electrocatalyst very promising for development of new cathode catalysts for fuel cells.

Abstract
BACKGROUND The present meta-analysis was designed to improve statistical power and review the effects of monoclonal antibodies against PCSK9 on clinical cardiovascular events. METHODS PubMed, Embase, Web of Science, and the Cochrane Library were searched from inception to May 2017. Studies considered to be eligible were randomized controlled trials about the effects of monoclonal antibodies against PCSK9 on clinical cardiovascular events. The primary endpoint was positively adjudicated cardiovascular events; the secondary endpoint comprised cardiac mortality, myocardial infarction (MI), coronary revascularization, stroke, and hospitalization for unstable angina. RESULTS We included 20 randomized controlled trials involving 67,934 patients. Monoclonal antibodies against PCSK9 were associated with a significant reduction in positively adjudicated cardiovascular events (relative risk [RR] = 0.87; 95% confidence interval [CI] = 0.81-0.93; z = 4.03; p = 0.000), MI (RR = 0.78; 95% CI = 0.71-0.86; z = 4.96; p = 0.000), coronary revascularization (RR = 0.81, 95% CI = 0.75-0.88; z = 4.93; p = 0.000), and stroke (RR = 0.76, 95% CI = 0.65-0.89; z = 3.47; p = 0.001). Monoclonal antibodies against PCSK9 did not reduce hospitalization rates due to unstable angina. The results of subgroup analysis showed that evolocumab was associated with a lower risk of positively adjudicated cardiovascular events, MI, coronary revascularization, and stroke without reducing cardiac mortality. Alirocumab reduced the incidence of cardiac mortality but not of other cardiovascular events, while bococizumab was associated with a reduced risk of stroke. CONCLUSION Monoclonal antibodies against PCSK9 were associated with a lower risk of positively adjudicated cardiovascular events, MI, coronary revascularization, and stroke.

Abstract
Objective: To analyze the clinical and genetic features of 15 cases with intellectual disability or developmental delay (ID/DD) complicated with congenital nystagmus. Method: The clinical characteristics and the results of laboratory tests, images and genetics of 15 patients with ID/DD complicated with congenital nystagmus, confirmed by gene diagnosis in the Department of Neurology, Children's Hospital Affiliated to Capital Institute of Pediatrics from March 2015 to October 2016, were retrospectively analyzed. The physiological function of 13 disease genes and the molecular signaling pathways were also comparatively studied. Result: The patients included 11 males and four females, with an age of 2 months-15 years (median age 27 months). The result of multiplex ligation-dependent probe amplification was positive in two patients only with hypomyelination on head MRI. Positive results were found in 13 patients with or without abnormal head MRI or other deformities using targeted capture technology and next generation sequencing. Two patients were diagnosed with Pelizaeus-Merzbacher disease, two had hypomyelination with an atrophy of the basal ganglia and cerebellum and two had oculocutaneous albinism. Pelizaeus-Merzbacher-like disease was found in one case, cerebro-oculo-facio-skeletal syndrome in one case, Rubinstein-Taybi syndrome in one case, mental retardation type 5 in one case, methylmalonic aciduria combined with hyperhomocysteinemia in 1 case, ataxia telangiectasia in one case, hypomyelinating leukodystrophy type 8 in one case, Marinesco-Sjögren syndrome in one case and CHARGE syndrome in one case. A total of 12 novo mutations were reported in this study. Conclusion: The causes of children with ID/DD complicated with congenital nystagmusis are complex. Comprehensive clinical and auxiliary examinations should be performed to improve the accuracy of the diagnosis. Reasonable application of different genetic testing methods can significantly improve the diagnostic accuracy of molecular genetic etiology in children with ID/DD.

Abstract
Objective: To investigate the prevalence and trend of overweight and obesity in children and adolescents aged 6-17 years between 2002 and 2012 in Guangdong province. Methods: A total of 7 075 children and adolescents aged 6-17 years were selected in Guangdong for nutritional survey in 2002 and a total of 2 319 children and adolescents aged 6-17 years were selected in nine counties/districts of Guangdong for nutritional survey during 2009-2012 through multi-stage random cluster sampling. The body height and weight of all the children and adolescents were measured. Results: The result of 2009-2012 survey indicated the average prevalence of overweight and obesity in the children and adolescents surveyed were 7.3% and 4.5%, respectively. The prevalence of overweight and obesity were higher in boys (8.9% and 6.5%) than in girls (5.3% and 2.2%), in rural area (9.3% and 5.6%) than in urban area (4.7% and 3.2%). Children and adolescents aged 9-11 years had a higher overweight and obesity rates compared with other age groups. Compared with 2002, except for obesity rate in urban girls, the prevalence of overweight and obesity in children and adolescents obviously increased. The increase rate was higher in rural area than urban area and in boys than in girls. Conclusions: Compared with 2002, the prevalence of overweight and obesity in children and adolescents in Guangdong obviously increased. The prevalence was much higher in boys, those living in rural area and those aged 9-11 years, thus more attention should be paid to them.

Abstract
Objective: To explore the factors influencing early treatment responses in adult with de novo acute myeloid leukemia (AML) . Methods: Data of consecutive newly-diagnosed AML (non-acute promyelocytic leukemia) adults were analyzed retrospectively. To assess the impact of clinical characteristics at diagnosis and induction regimen on achieving morphologic leukemia-free state (MLFS) , blood counts and minimal residual leukemia (MRD, positive MRD defined as RQ-PCR WT1 mRNA ≥0.6% and/or any level of abnormal blast population detected by flow cytometry) at the time of achieving MLFS. Results: 739 patients were included in this study. 406 (54.9%) patients were male, with a median age of 42 years (range, 18-65 years) . In the 721 evaluable patients, MLFS was achieved in 477 (66.2%) patients after the first induction regimen and 592 (82.1%) within two cycles. A total of 634 patients (87.9%) achieved MLFS, including 534 (84.2%) achieving a complete remission (CR, defined as MLFS with ANC ≥ 1×10(9)/L and PLT ≥ 100×10(9)/L) , 100 (15.8%) achieving a CRi (defined as MLFS with incomplete ANC or PLT recovery) , respectively. 260 (45.9%) patients of 566 (89.3%) who detected MRD at the time of achieving MLFS had positive MRD. Multivariate analyses showed that female gender, favorable-risk of SWOG criteria, IA10 and HAA/HAD as induction regimen were factors associated with achieving early MLFS. In addition, low bone marrow blasts, HGB ≥ 80 g/L, PLT counts<30×10(9)/L and mutated NPM1 without FLT3-ITD were factors associated with achieving MLFS after the first induction regimen; Negative FLT3-ITD mutation was factor associated with achieving MLFS within two cycles. PLT counts ≥30×10(9)/L and IA10, IA8 or HAA/HAD as induction chemotherapy were factors associated with achieving CR. Female gender, favorable-risk of SWOG criteria, FLT3-ITD mutation negative, mutated NPM1 without FLT3-ITD were factors associated with negative MRD. Conclusions: Female gender, favorable molecular markers or cytogenetics, and standard-dose induction regimen were key factors associated with higher probability of early and deep responses in adults with AML.

Abstract
OBJECTIVE Risk score (RS) model is a cost-effective tool to identify adults who are at high risk for diabetes. This study was to develop an RS model of type 2 diabetes (T2DM) prediction specifically for rural Chinese adults. METHODS A prospective whole cohort study (n = 28,251) and a sub-cohort study (n = 3043) were conducted from 2006-2014 and 2006-2008 to 2015 in rural Deqing, China. All participants were free of T2DM at baseline. Incident T2DM cases were identified through electronic health records, self-reported and fasting plasma glucose testing for the sub-cohort, respectively. RS models were constructed with coefficients (β) of Cox regression. Receiver-operating characteristic curves were plotted and the area under the curve (AUC) reflected the discriminating accuracy of an RS model. RESULTS By 2015, the incidence of T2DM was 3.3 and 7.7 per 1000 person-years in the whole cohort and the sub-cohort, respectively. Based on data from the whole cohort, the non-invasive RS model included age (4 points), overweight (2 points), obesity (4 points), family history of T2DM (3 points), meat diet (3 points), and hypertension (2 points). The plus-fasting plasma glucose (FPG) model added impaired fasting glucose (4 points). The AUC was 0.705 with a positive predictive value of 2.5% for the non-invasive model, and for the plus-FPG model the AUC was 0.754 with a positive predictive value of 2.5%. These models performed better as compared with 12 existing RS models for the study population. CONCLUSIONS Our non-invasive RS model can be used to identify individuals who are at high risk of T2DM as a simple, fast, and cost-effective tool for rural Chinese adults.

Abstract
Objective: To explore status of tyrosine kinase inhibitor (TKI) discontinuation in patients with chronic myeloid leukemia (CML) in the chronic phase (CP) in the real world, to analyze causes, factors and outcomes associated with TKI discontinuation and the possibility of pursuit treatment-free remission (TFR) in China. Methods: From January 2013 to August 2016, data of CML-CP patients in Peking University People's Hospital which were not enrolled in clinical trials were retrospectively collected and analyzed. Results: Data of 662 CML-CP patients were collected. With a median follow-up after TKI-therapy of 26 months (range, 3-187 months) , 187 patients (28.2%) experienced TKI cessation of at least 2 weeks. Causes of TKI discontinuation included hematologic adverse events 57.8% (n=108) , non-hematologic adverse events 30.4% (n=57) , financial burden 25.1% (n=47) , and others 7.0% (n= 13) . Multivariate analyses showed female, ≥40 years, no co-morbidity, and interval from diagnosis to TKI initiation ≥6 months, TKI switch and patients from other hospitals were factors associated with TKI discontinuation because of hematologic adverse effects. Female and patients from other hospitals were factors associated with TKI discontinuation because of non-hematologic adverse effect. TKI switch, generic TKI used and patients from other hospitals were factors associated with TKI discontinuation because of financial toxicity. Patients TKI discontinuation because of hematologic, non-hematologic or financial toxicity achieved a lower complete cytogenetic response or complete molecular response (CMR) than those with uninterrupted TKI-therapy. Patients with TKI discontinuation because of hematologic or financial toxicity had a shorter progression-free survival than those with uninterrupted TKI-therapy. 5 of 7 patients who obtained sustained CMR and discontinued TKI-therapy experienced disease recurrence with a median duration of 3 months (range, 2-32 months) . In 39 patients from other hospitals who aimed to confirm their optimal response of sustained CMR in Peking University People's Hospital, 21 (53.8%) were BCR-ABL positive. Conclusion: In the real world in China, half of CML-CP patients who discontinued TKI-therapy were incurred to TKI-related hematologic adverse effect, and both a quarter of them, TKI-related non-hematologic toxicities and financial toxicity, respectively. Discontinued TKI-therapy due to hematologic adverse events or financial toxicity was associated with lower TKI-therapy response rates. Nowadays, based on the Chinese situation, it is too early to talk about TFR.

Abstract
Objective: To analyze the prevalence of schistosomiasis in Hunan province, and provide scientific evidence for the control and elimination of schistosomiasis. Methods: The changes of infection rates of Schistosoma (S.) japonicum among residents and cattle in Hunan from 1984 to 2015 were analyzed by using dynamic trend diagram; and the time regression model was used to fit the infection rates of S. japonicum, and predict the recent infection rate. Results: The overall infection rates of S. japonicum in Hunan from 1984 to 2015 showed downward trend (95.29% in residents and 95.16% in cattle). By using the linear regression model, the actual values of infection rates in residents and cattle were all in the 95% confidence intervals of the value predicted; and the prediction showed that the infection rates in the residents and cattle would continue to decrease from 2016 to 2020. Conclusion: The prevalence of schistosomiasis was in decline in Hunan. The regression model has a good effect in the short-term prediction of schistosomiasis prevalence.

Abstract
Objective: To explore impact of minimal residual leukemia (MRD) on outcomes in the non-favorable risk adults with de novo acute myeloid leukemia (AML) . Methods: From January 2008 to February 2016, data of consecutive newly-diagnosed non-favorable risk adults with AML (non-APL) according to SWOG criteria who achieved morphologic leukemia-free state (MLFS) and received continuous chemotherapy were assessed retrospectively. Results: 292 AML patients were enrolled, 150 (51.4%) were male. Median age was 46 years (range, 18-65 years) . Using the SWOG cytogenetic classification, 186 (63.7%) , 49 (16.8%) and 57 (19.5%) patients belonged to intermediate, unfavorable and unknown categories, respectively. With a median follow-up period of 15 months (range, 1 to 94 months) in survivors, the probabilities of cumulative rates of relapse (CIR) , disease free survival (DFS) and overall survival (OS) at 2-years were 51.6%, 42.6% and 60.0%, respectively. Multivariate analyses showed that MRD positive (defined as Q-PCR WT1 mRNA ≥0.6% or any level of abnormal blast population detected by flow cytometry) after achieving MLFS and PLT<100×10(9)/L were common adverse factors affecting CIR and DFS. In addition, positive FLT3-ITD mutation and CRp/CRi had negatively impact on CIR, DFS and OS. Monosomal karyotype was adverse factors affecting CIR and OS. Age ≥44 years and unfavorable-risk of SWOG criteria were associated with shorter DFS. Conclusions: MRD level after achieving MLFS had prognostic significance on outcomes in non-favorable adults with AML who received continuous chemotherapy after achieving MLFS.

Abstract
Objective: To compare the efficacy and safety between Chinese generic imatinib (Xinwei®, Jiansu Hansoh Pharmaceutical Group Co., Ltd.) versus branded imatinib (Glivec®, Novartis) in patients with newly-diagnosed chronic myeloid leukemia in chronic phase (CML-CP). Methods: Patients with newly diagnosed CML-CP were enrolled and assigned to receive either Xinwei or Glivec at an initial dose of 400 mg/d according to patients' financial capability. The efficacy and adverse effects were evaluated. Results: From January 2014 to September 2015, 145 eligible patients were assigned to Xinwei (n=89) or Glivec (n=56) group. All patients were treated and followed up at least 3 months. At 3 months, the complete response rates were 95.5%(85/89) and 100%(56/56), major cytogenetic response rates were 74.2%(66/89) and 80.4%(45/56), and the proportions of achieving BCR-ALBIS≤10% were 76.1%(67/88) and 82.1%(46/56) in Xinwei and Glivec groups respectively (all P>0.05). With a median follow-up of 12 months, 2 patients in each group progressed to accelerate or blast phase. Hematologic and non-hematologic side effects were similar between the 2 groups. Conclusions: Early hematological, cytogenetic and molecular responses between Xinwei and Glivec are comparable in newly-diagnosed CML-CP patients. The progression rate and side effects are also similar between the 2 groups.

Abstract
OBJECTIVE To study the effects of metformin on streptozotocin-induced type 2 diabetes mellitus (T2DM) in rats. MATERIALS AND METHODS Wistar male rats were divided into two groups: standard diet (SD, n = 20) group and high-fat diet (HFD, n = 80) group. Twenty rats in HFD group were randomly treated with metformin (EI group). After 6 weeks, among rats in HFD group, 20 rats were intraperitoneally injected with citrate buffered saline (IR group), 20 rats treated with metformin per day for 4 weeks (LI group), and 20 rats were given nothing (DM group). Rats in SD group were injected with citrate buffered saline as normal control (NC) group. Moreover, streptozotocin (STZ) was used for inducing diabetes. The metabolic parameters, such as body weight, fasting blood glucose (FBG), fasting insulin concentration (FINS), total cholesterol (TC), total triglycerides (TG), low-density lipoprotein cholesterol (LDLC) and total bile acid (TBA) were measured. RESULTS Compared with SD group, the levels of body weight, FBG, TC, LDLC, TBA and FINS and AUC (glucose) were significantly higher in HFD group. After administration of metformin, the levels of FBG, TG, TC, LDLC and TBA in DM and LI group were higher than NC group. Besides, the FBG, TG, TC, TBA and LDLC levels in EI group were higher than DM group. CONCLUSIONS Metformin may help to improve the glucose and lipid metabolism by influencing the level of serum total bile acids. A combination of HFD and metformin could be effective in the treatment of rats with T2DM.

Abstract
Objective: To establish a method of isolation and primary culture of mice distal pulmonary artery smooth muscle cells (PASMCs) and identify the functional properties. Methods: PASMCs were harvested from the distal pulmonary artery (PA) tissue of mice by enzymatic digestion of collagenaseⅠand papain; and the growth characteristics were observed under inverted microscope and identified by Immunofluorescence technique. Effects on the intracellular calcium ion concentration of distal PASMCs were detected by Fura-2-AM fluorescent probe tracer under a fluorescence microscope in Krebs solution containing clopiazonic acid (CPA) and nifedipin (Nif). Results: PASMCs density reached approximately to 80% in a typical valley-peak-like shape after 6 days. Cell α-smooth muscle actin (α-SMA) immunofluorescence identified that 95% of the cultured cells were PASMCs. More than 95% PASMCs responded well to calcium-potassium Krebs solution (potassium ion concentration of 60 mmol/L) and showed a rapid increase in basal [Ca(2+) ](i) after 1 minute's perfusion (Δ[Ca(2+) ](i)>50), which demonstrated that the voltage-dependent calcium channels (VDCC) of distal PASMCs were in good function; after the perfusion of calcium Krebs, calcium-free/calcium-Krebs containing CPA and Nif, distal PASMCs showed two typical peaks, indicated the full function of store-operated calcium channel (SOCC) in distal PASMCs. Conclusion: This experiment successfully established a stable and reliable mice distal PASMCs model and the study of pulmonary vascular diseases could benefit from its higher purity and better functional condition.

Abstract
Objective: To investigate the clinical manifestation, cytogenetics, gene mutations and prognostic factors of chronic neutrophilic leukemia (CNL) . Methods: 16 CNL cases, according to WHO (2016) -definition, were reviewed retrospectively. Identifications of the CSF3R, ASXL1, SETBP1, CALR and MPL mutations were performed by direct sequencing. JAK2 V617F mutation was detected by AS-PCR. Results: Of the 16 CNL patients, the median age was 64 (43-80) years with a male predominance of 75% (12/16) . The median hemoglobin was 114 (81-154) g/L, with median WBC of 41.20 (26.05-167.70) (10(9)/L and median PLT of 238 (91-394) ×10(9)/L.The median level of marrow fibrosis (MF) was 1 (0-3) degree. There was no other cytogenetic abnormalities except t (1;7) (p32;q11) , +21 and 14ps+ for each. All the 16 CNL patients harbored CSF3R T618I mutation. ASXL1 mutations were identified in 81% (13/16) , while SETBP1 mutations were confirmed in 63% (10/16) . The CALR K385fs*47 mutation was found. There was no mutation in JAK2 V617F or MPL in the above 16 patients. The median overall survival (OS) of patients presented with WBC≥50×10(9)/L at diagnosis (11 months) was significantly shorter than of WBC<50×10(9)/L (39 months, P=0.005) . Conclusion: CSF3R T618I mutation was specific for CNL. The median OS of CNL patients was 24 months, and WBC≥50×10(9)/L at diagnosis was an unfavorable prognostic factor.

Abstract
OBJECTIVE To investigate dynamic change of cadmium body burden and renal dysfunction among residents living in cadmium-polluted areas. METHODS From April to July of 2011, the cadmium-polluted areas of northern Guangdong province in China was chosen as the study site. Based on the levels of cadmium pollution in soil and rice, the survey areas were divided into low exposed group (average concentration of cadmium was 0.15-0.40 mg/kg, 0.5-1.0 mg/kg in rice and soil, respectively) and high exposed group (average concentration of cadmium was >0.40 mg/kg, >1.0 mg/kg in rice and soil, respectively). Stratified random sampling and cluster sampling method of epidemiological investigations were carried out among 414 local residents who lived in cadmium exposure areas for more than 15 years, aged above 40, and without occupational cadmium exposure, including 168 and 246 residents in low and high exposed group, respectively. From March to June of 2014, 305 respondents of those who participated in 2011 were successfully traced, including 116 and 189 respondents in low and high exposed group, respectively. We used health questionnaires to acquire their health status. Home-harvested rice and vegetable samples were collected using quartering method for detection of cadmium level, including 190 rice samples, 161 vegetable samples in 2011 and 190 rice samples, 153 vegetable samples in 2014. Urine specimens of residents were collected for the detection of urinary cadmium and creatinine as well as renal dysfunction biomarkers, namely, N-acetyl-beta-D-glucosamidase (NAG) and β2-microglobulin (β2-MG), respectively. In 2011 and 2014, Chi-square test was used to investigate the differences of abnormality of cadmium concentration in rice, vegetables and urinary cadmium, β2-MG, and NAG that were expressed as odds ratio(OR) and 95% confidence intervals (95%CI). RESULTS In 2011 and 2014, cadmium concentration P50 (P25-P75) in rice was 0.43 (0.17-1.10) mg/kg, and 0.42 (0.20-1.14) mg/kg, respectively (Z=-0.77,P=0.440). In 2011 and 2014, cadmium concentrations P50 (P25-P75) in vegetables were 0.13 (0.07-0.34) mg/kg, and 0.25(0.12-0.59) mg/kg, respectively, with abnormal rates of 38.5%(62/161) and 60.8%(93/153), respectively. In 2014, both average concentration and abnormal rate of cadmium in vegetables were higher than those in 2011 (Z=-4.69, P<0.001 and χ(2)=15.58,P<0.001). Concentrations of urinary cadmium P50 (P25-P75) in high exposed group were 7.90 (3.96-14.91) μg/g creatinine, 8.64 (4.56-17.60) μg/g creatinine in 2011 and 2014, respectively. Contrary to that in 2011, urinary cadmium of high exposed group was significantly increased in 2014 (Z=-2.80, P=0.005). In 2011 and 2014, concentrations of β2-MG, NAG P50 (P25-P75) were 0.15(0.07-0.29) μg/g creatinine, 0.15 (0.07-0.45) μg/g creatinine, and 7.12 (5.05-10.65) U/g creatinine, 13.55(9.1-19.84) U/g creatinine, respectively, with abnormal rates of 7.5% (23/305), 15.1% (46/305), 8.2% (25/305) , and 33.8% (103/305), respectively. Compared with baseline in 2011, average concentrations of β2-MG, NAG significantly increased in 2014 (Z=-2.263, P=0.024 and Z=-12.52, P<0.001), and abnormal rates of β2-MG, NAG were also higher in 2014 (χ(2)=15.61 , P<0.001 and χ(2)=64.72, P<0.001), with odds ratio(OR) of 2.00 (95%CI:1.23-3.24) and 4.12 (95%CI:2.87-5.92). CONCLUSION Environmental cadmium pollution of crops such as rice and vegetables in survey areas continued to remain high. Body burden of cadmium might kept at sustainably high levels and renal dysfunction was worsened after continuous, long-term cadmium exposure. Our results suggested that NAG might be more sensitive than β2-MG to serve as an indicator for an individual's future tubular function.

Abstract
Pt1ML/Pd3Al, which comprises a Pd3Al core protected by a Pt monolayer, may experience Al dealloying because of the strong affinity of Al toward O. To circumvent this issue, the Pt2ML/Os/Pd3Al catalyst has been designed to suppress the migration of Al by inserting an Os monolayer at the interface between the Pd3Al core and two Pt monolayers. On the basis of segregation energies, Al leaching from the core to the 1st layer is determined to be endothermic even under O coverage, indicating an energetic preference for Al to reside in the core structure. The Pt2ML/Os/Pd3Al catalyst benefits from the energetic disadvantage of the inward movement of Os and the presence of the 2 ML Pt layer. As an ORR electrocatalyst, the relatively weak adsorption ability of Pt2ML/Os/Pd3Al suggests improved ORR activity. Finally, a representative OOH association mechanism with low reaction barriers of 0.46, 0.31, 0.38 and 0.41 eV for the OOH formation, OOH dissociation, OH formation and H2O formation steps suggests that the catalyst can effectively activate the O-O bond and eliminate OH, which can act as a catalytic poison. These findings suggest the design of stable sandwich catalysts as potential candidates for ORR electrocatalysis.

Abstract
Objective: To study the effect of chronic hypoxia on pulmonary arterial remodeling and Krüppel-like zinc-finger transcription factor 5 (KLF5) protein expression in pulmonary artery smooth muscles in a hypoxia-induced pulmonary hypertension model. Methods: Totally 20 adult SD rats (200-250 g) were divided into a normoxia group and a chronic hypoxia group by the random number table. Rats in the chronic hypoxia group were put in an automatic hypoxia box for 21 days. After that, right ventricular systolic pressure (RVSP), mean right ventricular pressure (mRVP) and RV/(LV+ S) were measured. Lung tissue sections were made. The lumen area, ratio of wall thickness to radius of pulmonary artery were gauged by using the Image Pro Plus software. Primary PASMCs were cultured in oxygen-deficient environment (4% O2)or normal oxygen environment (21% O2)for 60 hours respectively, and then total protein or RNA were extracted for Western blotting and Q-PCR analysis.KLF5 protein expression in rat pulmonary arterial smooth muscle and pulmonary arterial smooth muscle cells was detected by Western blot. Results: Compared with the normoxia group(28.3±0.4), (11.3±1.0)mmHg (1 mmHg=0.133 kPa), the RVSP and mRVP in the chronic hypoxia group [(43.9±1.3), (26.5±2.3)mmHg] were significantly increased(P<0.05). The Rv/(LV+ S)of the chronic hypoxia group was(0.48±0.03), markedly higher than that of the normoxia group(0.27±0.01, P<0.05). The luminal area/total area of artery in the chronic hypoxia group decreased to (46.1±6.6)% compared with that in the normoxia group [(68.73±3.06)%, P<0.05]. The wall thickness/arterial radius(WT%)of the chronic hypoxia group increased up to (5.64±0.32)% as compared with (3.7±0.4)% of the normoxia group (P<0.05). The level of KLF5 protein in pulmonary arterial smooth muscles of the chronic hypoxia group was (21.6±7.2) times that of the normoxia group (P<0.05). Conclusion: Hypoxia induced the increase of RVSP, mRVP, RV/(LV+ S), accompanied with pulmonary arterial remodeling. The underlying mechanism of the artery change may be related to up-regulated expression of KLF5.

Abstract
Objective: To evaluate the application of single nucleotide polymorphism (SNP)-microarray and target gene sequencing technology in the clinical molecular genetic diagnosis of unexplained intellectual disability(ID) or developmental delay (DD). Method: Patients with ID or DD were recruited in the Department of Neurology, Affiliated Children's Hospital of Capital Institute of Pediatrics between September 2015 and February 2016. The intellectual assessment of the patients was performed using 0-6-year-old pediatric examination table of neuropsychological development or Wechsler intelligence scale (>6 years). Patients with a DQ less than 49 or IQ less than 51 were included in this study. The patients were scanned by SNP-array for detection of genomic copy number variations (CNV), and the revealed genomic imbalance was confirmed by quantitative real time-PCR. Candidate gene mutation screening was carried out by target gene sequencing technology.Causal mutations or likely pathogenic variants were verified by polymerase chain reaction and direct sequencing. Result: There were 15 children with ID or DD enrolled, 9 males and 6 females. The age of these patients was 7 months-16 years and 9 months. SNP-array revealed that two of the 15 patients had genomic CNV. Both CNV were de novo micro deletions, one involved 11q24.1q25 and the other micro deletion located on 21q22.2q22.3. Both micro deletions were proved to have a clinical significance due to their association with ID, brain DD, unusual faces etc. by querying Decipher database. Thirteen patients with negative findings in SNP-array were consequently examined with target gene sequencing technology, genotype-phenotype correlation analysis and genetic analysis. Five patients were diagnosed with monogenic disorder, two were diagnosed with suspected genetic disorder and six were still negative. Conclusion: Sequential use of SNP-array and target gene sequencing technology can significantly increase the molecular genetic etiologic diagnosis rate of the patients with unexplained ID or DD. Combined use of these technologies can serve as a useful examinational method in assisting differential diagnosis of children with unexplained ID or DD.

Abstract
AIM This study was designed to determine any rebleeding after atorvastatin treatment following spontaneous intracerebral hemorrhage (ICH) in a prospective safety trial. PATIENTS Atorvastatin (80 mg/day) therapy was initiated in 6 patients with primary ICH with admission Glasgow Coma Score (GCS) >5 within 24 hours of ictus and continued for 7 days, with the dose tapered and treatment terminated over the next 5 days. Patients were studied longitudinally by multiparametric magnetic resonance imaging (MRI) at three time points: acute (3 to 5 days), subacute (4 to 6 weeks) and chronic (3 to 4 months). Imaging sequences included T1, T2-weighted imaging (T2WI), diffusion tensor imaging (DTI) and contrast-enhanced MRI measures of cerebral perfusion, blood volume and blood-brain barrier (BBB) permeability. Susceptibility weighted imaging (SWI) was used to identify primary ICH and to check for secondary rebleeding. Final outcome was assessed using Glasgow Outcome Score (GOS) at 3-4 months. RESULTS Mean admission GCS was 13.2±4.0 and mean GOS at 3 months was 4.5±0.6. Hemorrhagic lesions were segmented into core and rim areas. Mean lesion volumes decreased significantly between the acute and chronic study time points (p=0.008). Average ipsilateral hemispheric tissue loss at 3 to 4 months was 11.4±4.6 cm3. MRI showed acutely reduced CBF (p=0.004) and CBV (p=0.002) in the rim, followed by steady normalization. Apparent diffusion coefficient of water (ADC) in the rim demonstrated no alterations at any of the time points (p>0.2). The T2 values were significantly elevated in the rim acutely (p=0.02), but later returned to baseline. The ICH core showed sustained low CBF and CBV values concurrent with a small reduction in ADC acutely, but significant ADC elevation at the end suggestive of irreversible injury. CONCLUSION Despite the presence of a small, probably permanent, cerebral lesion in the ICH core, no patients exhibited post-treatment rebleeding. These data suggest that larger, Phase 2 trials are warranted to establish long term clinical safety of atorvastatin in spontaneous ICH.

Abstract
OBJECTIVES To assess tyrosine kinase inhibitor (TKI) treatment status in patients with chronic myeloid leukemia (CML) in China and analyze the response-associated factors. METHODS From May to November in 2014, anonymous questionnaires were distributed to adult CML patients who were receiving TKI treatment all over China. RESULTS 1 038 questionnaires were collected, 949 questionnaires were evaluable. Of the 949 evaluable respondents, 549 (58%) were male with the median age of 41 years (range, 18 to 88 years). 623 (66%) respondents lived in an urban area and 449 (47%) had an education level ≥ a bachelor degree. 888 (94%) respondents were in the chronic phase at diagnosis, and 690 (78%) of them started TKI treatment within one year after diagnosis. 794 (84%) respondents were on imatinib, 768 (81%) on the branded. With a median TKI treatment duration of 3 years (range, <1 to 13 years), 708 of 834 (85%) evaluable respondents achieved Ph- negative (i.e. complete cytogenetic response, CCyR), and 497 of 859 (46% ) BCR- ABL negative (i.e. complete molecular response, CMR). Multivariate analyses showed that female (OR=1.8, 95% CI 1.1-2.8,P=0.019 andOR=1.5, 95% CI 1.1-2.0,P=0.015), TKI treatment duration >3 years (OR=4.1, 95% CI 2.6- 6.5,P<0.001 andOR=3.7, 95% CI 2.7- 5.1,P< 0.001) and imatinib taken (OR=2.1, 95% CI 1.2-3.7,P=0.007 andOR=3.3, 95% CI 2.1-5.1,P<0.001) were factors affecting achieving both CCyR and CMR. In addition, higher education level (OR=2.0, 95% CI 1.3- 3.1,P=0.003), starting TKI treatment <1 year (OR=2.4, 95% CI 1.5- 3.8,P<0.001) and branded drugs received (OR=2.4, 95% CI 1.4- 4.0,P=0.001) were factors affecting achieving a CCyR. In 884 respondents, 534 (62%) reported " heavy financial burden" as the biggest treatment impediment, only 152 (17%) reported " poor quality of life related to adverse effects of TKI". CONCLUSIONS The survey showed that majority of the Chinese CML patients received imatinib as a TKI therapy, and most of the patients achieved satisfied responses by TKI. Financial burden became the major obstacle during TKI treatment.

Abstract
UNLABELLED Screening and appropriate treatment for osteoporosis has been proven to be cost-effective in many populations; however, it is not clear in the Chinese population. Simulations using a validated health economics model suggest that screening for osteoporosis in Chinese women is cost-effective and may even be cost-saving in Chinese post-menopausal women. INTRODUCTION This study aimed at determining the cost-effectiveness of osteoporosis screening strategies in post-menopausal Chinese women. METHODS A validated state-transition microsimulation model with a lifetime horizon was used to evaluate the cost-effectiveness of different screening strategies with treatment of alendronate compared with current osteoporosis management in China. Osteoporosis screening strategies assessed were (1) universal screening with dual-energy X-ray absorptiometry (DXA) alone; (2) Osteoporosis Self-Assessment Tool for Asians (OSTA) + DXA; and (3) quantitative ultrasound (QUS) + DXA with rescreening at 2, 5 or 10-year intervals for patients screened negative by DXA. The study was performed from the Chinese healthcare payer's perspective. All model inputs were retrieved from publically available literature. Uncertainties were addressed by one-way and probabilistic sensitivity analysis. RESULTS Screening strategies all improved clinical outcomes at increased costs, and each were cost-effective compared with no screening in women aged 55 years given the Chinese willingness-to-pay threshold of USD 20,000 per quality-adjusted life year (QALY) gained. Pre-screening with QUS and subsequent DXA screening if the QUS T-score ≤ -0.5 with a 2-year rescreening interval was the most cost-effective strategy with the highest probability of being cost-effective across all non-dominated strategies. Screening strategies were cost-saving if screenings were initiated from age 65 years. One-way sensitivity analyses indicated that the results were robust. CONCLUSIONS Pre-screening with QUS with subsequent DXA screening if the QUS T-score ≤ -0.5 with a 2-year rescreening interval in the Chinese women starting at age 55 is the most cost-effective. In addition, screening and treatment strategies are cost-saving if the screening initiation age is greater than 65 years.

Abstract
This study investigated the effects of FUT3 gene expression inhibition with miRNA on the proliferation, invasion and migration abilities of KATO-III cells. KATO-III cells were transfected with plasmid pcDNA™6.2-GW/EmGFP-FUT3-miR(FUT3-miRNA) and negative control plasmid in mediation of liposome, respectively, using untransfected cells as blank controls. Forty-eight hours after transfection, FUT3 mRNA levels were tested by RT-PCR. Levels of sLeA proteins were assayed by Western blot. The effects of FUT3-miRNA on the proliferation, invasion and migration of KATO-III cells were determined by CCK8 testing and Transwell assays, respectively. Results indicate that the transfection of FUT3-miRNA may down-regulate sLeA protein expression on the surface of KATO-III cells, and significantly inhibit cell proliferation (p<0.05). As compared to the negative and blank control groups, the number of invasion and migration cells in the FUT3-miRNA group decreased significantly (each p<0.05). Experimental results indicate that the miRNA expression vector which targets the FUT3 gene can effectively inhibit the proliferation, migration and invasion abilities of KATO-III cells.

Abstract
OBJECTIVE To investigate the prognostic significance of proportion of the blasts in bone marrow on day 14 (D14) during induction chemotherapy in patients with adult Ph-negative acute lymphoblastic leukemia (Ph (-) ALL). METHODS Newly diagnosed Ph (-) ALL patients with bone marrow morphology analysis on day 14 during induction chemotherapy were analyzed retrospectively. The proportion of the D14 blasts which had an impact on achieving a CR by the first induction chemotherapy and outcomes were determined by ROC curve. RESULTS 166 ALL patients including 94 male and 72 female were analyzed. The median age was 32 years (range, 18-64 years). The CR rate by the first induction chemotherapy was 74.7% with a total CR rate as 93.3%. By ROC analysis, 7.5% of the D14 blasts had the best sensitivity and specificity. The patients with D14 blasts ≥7.5% had lower CR rates after the first and overall induction chemotherapy compared with those with D14 blasts <7.5% (42.7% vs 85.9%, P<0.001 and 75.9% vs 95.6%, P=0.001 respectively). The probabilities of 5-year disease free survival (DFS) and 5-year overall survival (OS) were higher in the patients with D14 blasts<7.5% than those with D14 blasts ≥7.5% (49.8% vs 29.6%, P=0.006 and 52.4% vs 32.6%, P=0.010 respectively). Multivariate analysis showed that higher WBC or central nervous system leukemia at diagnosis, D14 blasts ≥7.5%, no CR after the first induction chemotherapy and receiving consolidation and maintenance chemotherapy rather than transplant were associated with poor outcomes. CONCLUSIONS Higher proportion of D14 blasts in bone marrow during the first induction therapy indicated poor prognosis in adult Ph(-) ALL.

Abstract
Nickel metal hydride (Ni-MH) batteries have demonstrated key technology advantages for applications in new-energy vehicles, which play an important role in reducing greenhouse gas emissions and the world's dependence on fossil fuels. However, the poor high-rate dischargeability of the negative electrode materials-hydrogen storage alloys (HSAs) limits applications of Ni-MH batteries in high-power fields due to large polarization. Here we design a hybrid electrode by integrating HSAs with a current collector of three-dimensional bicontinuous nanoporous Ni. The electrode shows enhanced high-rate dischargeability with the capacity retention rate reaching 44.6% at a discharge current density of 3000 mA g(-1), which is 2.4 times that of bare HSAs (18.8%). Such a unique hybrid architecture not only enhances charge transfer between nanoporous Ni and HSAs, but also facilitates rapid diffusion of hydrogen atoms in HSAs. The developed HSAs/nanoporous metals hybrid structures exhibit great potential to be candidates as electrodes in high-performance Ni-MH batteries towards applications in new-energy vehicles.

Abstract
The polypeptide N-acetylgalactosaminyltransferase-like protein 5 (GALNTL5) is a newly identified protein that is specifically expressed in testis tissue and participates in spermatogenesis. In this study, we characterized a novel bovine GALNTL5 splice variant, designated as GALNTL5-AS, by using real-time polymerase chain reaction (RT-PCR) and clone sequencing methods. The novel GALNTL5 isoform was derived from the complete transcript, GALNTL5-complete, via alternative splicing (AS). The pattern of the splice variant was exon skipping. Bovine GALNTL5 transcripts were expressed in the testis, as demonstrated by RT-PCR. The expression levels of both transcripts were higher in adult testes than in calf testes (P < 0.05). In addition, prediction analysis showed that the GALNTL5-AS transcript only encoded 122 amino acids and lost its glycosyltransferase 1 and Gal/GalNAc-T motifs, which may result in a dysfunctional protein compared with the predominant transcript GALNTL5-complete. This study improves our understanding of the bovine GALNTL5 gene function during bull sperm formation.

Abstract
Polymorphonuclear neutrophil (PMN) leukocytes are primary phagocytic cells of the bovine mammary gland and a first line of defense against invading pathogens during bovine mastitis infection. Cluster of differentiation 14 (CD14) is mainly expressed in macrophages and neutrophils and acts as a co-receptor that binds bacterial lipopolysaccharide (LPS) and recruits PMNs to CD14-LPS complexes in mammary epithelial cells. In this study, we identified a novel splice variant in PMNs, named CD14-SV, characterized by a deleted region from c.143-579 nt compared to the CD14 reference mRNA sequence. Moreover, a single nucleotide polymorphism (c.523 A>G) in exon 2 of CD14 was identified and found to modify the secondary structure and hydrophilicity of the CD14 protein. Association analysis also showed that the milk somatic cell score, an indicator of mastitis, of cows with the GG genotype was lower than that of cows with the AA and AG genotypes. Our findings suggest that the expression of CD14 in bovine blood PMNs is regulated by alternative splicing, and that CD14-SV is a candidate functional marker that may influence mastitis-resistance in dairy cows.

Abstract
Clinical studies have shown that probiotics positively affect oral health by decreasing gum bleeding and/or reducing salivary counts of certain oral pathogens. Our aim was to investigate the inhibitory effect of six probiotic lactobacilli against opportunistic oral Candida species. Sugar utilisation by both lactobacilli and Candida was also assessed. Agar overlay assay was utilised to study growth inhibition of Candida albicans, Candida glabrata and Candida krusei by Lactobacillus rhamnosus GG, Lactobacillus casei Shirota, Lactobacillus reuteri SD2112, Lactobacillus brevis CD2, Lactobacillus bulgaricus LB86 and L. bulgaricus LB Lact. The inhibitory effect was measured at pH 5.5, 6.4, and 7.2, respectively, and in the presence of five different carbohydrates in growth medium (glucose, fructose, lactose, sucrose, and sorbitol). Growth and final pH values were measured at two-hour time points to 24 h. L. rhamnosus GG showed the strongest inhibitory activity in fructose and glucose medium against C. albicans, followed by L. casei Shirota, L. reuteri SD2112 and L. brevis CD2. None of the lactobacilli tested affected the growth of C. krusei. Only L. rhamnosus GG produced slight inhibitory effect on C. glabrata. The lower pH values led to larger inhibition zones. Sugar fermentation profiles varied between the strains. L. casei Shirota grew in the presence of all sugars tested, whereas L. brevis CD2 could utilise only glucose and fructose. All Candida species metabolised the available sugars but the most rapid growth was observed with C. glabrata. The results suggest that commercially available probiotics differ in their inhibitory activity and carbohydrate utilisation; the above properties are modified by different pH values and sugars with more pronounced inhibition at lower pH.

Abstract
OBJECTIVE To analyze the difference of efficacy and prognostic factors between MA and CAG induction chemotherapy in elderly acute myelogenous leukemia (AML) patients. METHODS From April 2009 to September 2015, 103 consecutive hospitalized 60-plus-year-old AML patients were retrospectively analyzed. NPM1 positive FLT3-ITD negative accounted for 17 cases (16.7%). Sixty-five patients received MA regimen and thirty-eight patients received CAG regimen. MA group had higher WBC and FLT3-ITD positive mutations at diagnosis compared with CAG group (P=0.001, P=0.005; respectively). The median follow-up was 13 months for all patients and 17 months for the survivors. RESULTS Six patient (5.8%) died in early phase. Complete remission (CR) rate after the first cycle of induction chemotherapy was 51.5% (50/97). Overall CR rate was 70.1% (68/97). CR rate after the first cycle of induction chemotherapy and overall CR rate were indiscriminate between MA and CAG regimen. The time to neutrophil count recovery, the time to platelet count recovery and the number of platelet transfusions were indiscriminate between MA and CAG regimen. Among 68 CR patients, 23 patients relapsed at median 9 months, and cumulative incidence of relapse (CIR) at 3 years was (52.5±10.1)%. Median overall survival (OS) was 20 months. OS rate at 3 years was 32.2%. Median disease-free survival (DFS) was 28 months. DFS rate at 3 years was 43.7%. CIR, DFS and OS at 3 years were indiscriminate between MA and CAG regimen. Multivariate analysis showed that less than 70 years of age (P=0.001), achieved CR (P<0.001), and NPM1 (+) FLT3-ITD(-) mutation (P=0.044) were the independent factors for increasing OS. NPM1(+) FLT3-ITD(-) mutation was the independent factor for increasing DFS (P=0.042). Patients were classified by three prognosis factors: <70 ages, CR, and NPM1(+)FLT3-ITD(-) mutation. Patients with no poor prognosis factors were classified as low risk (n=13), with one factor as medium risk (n=52) and with two and more factors as high risk (n=31). There were significant differences in OS rate and DFS rate at 3 years for 3 groups patients (60.5% vs 48.1% vs 0, P<0.001; 60.2% vs 39.4% vs 0, P=0.045; respectively). OS and DFS at 3 years for 3 groups' patients were indiscriminate between MA and CAG regimen. CONCLUSIONS There was indiscrimination of efficacy among MA and CAG induction chemotherapy in old AML patients. Less than 70 years of age, CR and NPM1(+)FLT3-ITD(-) mutation were the independent factors for better survival.

Abstract
BACKGROUND AND PURPOSE The demonstration of prominent medullary veins in the deep white matter ipsilateral to acute ischemic stroke has been shown to predict poor clinical outcome. We have investigated the prognostic implications of prominent medullary veins in patients with subacute stroke who present outside the therapeutic window for revascularization therapy. MATERIALS AND METHODS Forty-three consecutive patients with ischemic stroke in the middle cerebral artery territory presenting within 3-7 days of ictus were enrolled. The presence of prominent medullary veins in the periventricular white matter of the ipsilateral and contralateral medullary vein hemispheres was recorded. Perfusion-weighted imaging was used to calculate differences in hemispheric CBF from corresponding areas. Clinical outcome was classified as good if the modified Rankin Scale score was <3. RESULTS Prominent medullary veins were observed in 24/43 patients with 14 ipsilateral medullary veins and 10 contralateral medullary veins. The ipsilateral medullary vein was independently associated with poor outcome (odds ratio, 11.19; P = .046). The contralateral medullary vein was not independently predictive of outcome but was significantly more common in patients with good outcome (90.0% contralateral medullary veins). A mean 64.5% decrease and a 52.4% increase of differences in hemispheric CBF were found in ipsilateral medullary veins and contralateral medullary veins, respectively. CONCLUSIONS The ipsilateral medullary vein was a significant predictive biomarker of poor clinical outcome after stroke and was associated with hypoperfusion. The contralateral medullary vein was associated with good clinical outcome, and we hypothesize that prominent contralateral medullary veins indirectly reflect increased CBF in the ipsilateral hemisphere due to spontaneous recanalization or collateral flow.

Abstract
Leukemia is a malignant proliferative disease of blood system, which is caused by hyperplasia of white blood cells and infiltration into other tissues and organs with blood flow, leading to a series of clinical manifestations. In this study, we detected the expression of HOXA7 gene in human acute promyelocytic leukemia cell line NB4. The expression level of HOXA7 decreased in the presence of ATRA, which was able to inhibit the proliferation of NB4 cells. Furthermore, ATRA altered the morphology of NB4 cells. The study suggested that HOXA7 might be a new gene candidate that influences the maturation of acute myeloid leukemia, and provided the molecular basis for the treatment for acute promyelocyticleukemia.

Abstract
Rapidly developing and intensive animal husbandry of livestock is a major contributor to global environmental pollutions. Large quantities and high concentrations of manure waste that contains phytate phosphorus are generated. The use of phytase can effectively solve the problem of high phosphorus pollution in the fecal material of monogastric animals. Enviropigs, producing phytase in the salivary glands and secreting the enzyme in the saliva, were first generated at the University of Guelph (Guelph, ON, Canada) in 1999. However, phytase is easily inactivated in digestive processing. To address this problem, we improved the transgene construct and successfully generated phytase transgenic pigs by handmade cloning. The Escherichia coli periplasmic phosphoanhydride phosphohydrolase (appA) gene was subcloned. Using fragment substitution method, we designed a phytase gene that was insensitive to cleavage by pepsin and trypsin and had a higher affinity for the substrate. After codon optimization, the designed phytase gene was named Cafp and subcloned downstream of the pig parotid secretory protein (PSP) gene promoter. The tissue-specific vector p-PSP-Intron-Cafp was constructed and transferred into Landrace fetal fibroblasts by electroporation. The cell lines carrying Cafp were used as nuclear donors in handmade cloning. Cloned embryos were cultured in vitro to blastocysts and transferred to recipient sows. The presence of Cafp was tested by PCR and sequencing of cloned pigs. Phytase activity in saliva, feed, and feces was detected by the ammonium molybdate method with a slight modification. Immunohistochemistry (IHC) was used to determine tissue-specific expression. Three cell lines carrying Cafp were obtained. We generated 1027 blastocysts; 712 were of good quality and transferred to 6 recipients. Fourteen piglets were born, of which 6 survived. The PCR and sequencing results showed that 7 (3 live and 4 dead) of the 14 piglets carried Cafp. Phytase activity in the saliva of the 6 live cloned pigs was tested at 4 months of age and only 1 pig had 0.155 FTU mL–1 enzyme activity. The enzyme in the other 2 pigs may be inactivated in the transgenic parotid gland. Among all the transgenic pigs, the highest phosphorus digestion rate was 59.2% of intake, which represents a 25.4% decrease in fecal emissions compared with the average of controls. The IHC results on the 3 later dead, Cafp-positive pigs showed that the transgene was expressed only in parotids, confirming tissue-specific gene expression. In summary, cleavage-resistant phytase transgenic pigs were successfully produced through handmade cloning. The cloned pigs offer a unique biological approach to manage phosphorus nutrition and environmental pollution in animal husbandry.
