BACKGROUND: Both medication and non-medication therapies are effective approaches to control blood pressure (BP) in hypertension patients. However, the association of joint changes in antihypertensive medication use and healthy lifestyle index (HLI) with BP control among hypertension patients is seldom reported, which needs to provide more evidence by prospective intervention studies. We examined the association of antihypertensive medication use and HLI with BP control among employees with hypertension in China based on a workplace-based multicomponent intervention program. METHODS: Between January 2013 and December 2014, a cluster randomized clinical trial of a workplace-based multicomponent intervention program was conducted in 60 workplaces across 20 urban areas in China. Workplaces were randomly divided into intervention (n = 40) and control (n = 20) groups. Basic information on employees at each workplace was collected by trained professionals, including sociodemographic characteristics, medical history, family history, lifestyle behaviors, medication status and physical measurements. After baseline, the intervention group received a 2-year intervention to achieve BP control, which included: (1) a workplace wellness program for all employees; (2) a guidelines-oriented hypertension management protocol. HLI including nonsmoking, nondrinking, adequate physical activity, weight within reference range and balanced diet, were coded on a 5-point scale (range: 0-5, with higher score indicating a healthier lifestyle). Antihypertensive medication use was defined as taking drug within the last 2 weeks. Changes in HLI, antihypertensive medication use and BP control from baseline to 24 months were measured after the intervention. RESULTS: Overall, 4655 employees were included (age: 46.3 ± 7.6 years, men: 3547 (82.3%)). After 24 months of the intervention, there was a significant improvement in lifestyle [smoking (OR = 0.65, 95% CI: 0.43-0.99; P = 0.045), drinking (OR = 0.52, 95% CI: 0.40-0.68; P < 0.001), regular exercise (OR = 3.10, 95% CI: 2.53-3.78; P < 0.001), excessive intake of fatty food (OR = 0.17, 95% CI: 0.06-0.52; P = 0.002), restrictive use of salt (OR = 0.26, 95% CI: 0.12-0.56; P = 0.001)]. Compare to employees with a deteriorating lifestyle after the intervention, those with an improved lifestyle had a higher BP control. In the intervention group, compared with employees not using antihypertensive medication, those who consistent used (OR = 2.34; 95% CI: 1.16-4.72; P = 0.017) or changed from not using to using antihypertensive medication (OR = 2.24; 95% CI: 1.08-4.62; P = 0.030) had higher BP control. Compared with those having lower HLI, participants with a same (OR = 1.38; 95% CI: 0.99-1.93; P = 0.056) or high (OR = 1.79; 95% CI: 1.27~2.53; P < 0.001) HLI had higher BP control. Those who used antihypertensive medication and had a high HLI had the highest BP control (OR = 1.88; 95% CI: 1.32-2.67, P < 0.001). Subgroup analysis also showed the consistent effect as the above. CONCLUSION These findings suggest that adherence to antihypertensive medication treatment and healthy lifestyle were associated with a significant improvement in BP control among employees with hypertension.

Objective: To investigate the effect of the AML1-ETO (AE) fusion gene on the biological function of U937 leukemia cells by establishing a leukemia cell model that induces AE fusion gene expression. Methods: The doxycycline (Dox) -dependent expression of the AE fusion gene in the U937 cell line (U937-AE) were established using a lentivirus vector system. The Cell Counting Kit 8 methods, including the PI and sidanilide induction, were used to detect cell proliferation, cell cycle-induced differentiation assays, respectively. The effect of the AE fusion gene on the biological function of U937-AE cells was preliminarily explored using transcriptome sequencing and metabonomic sequencing. Results: ①The Dox-dependent Tet-on regulatory system was successfully constructed to regulate the stable AE fusion gene expression in U937-AE cells. ②Cell proliferation slowed down and the cell proliferation rate with AE expression (3.47±0.07) was lower than AE non-expression (3.86 ± 0.05) after inducing the AE fusion gene expression for 24 h (P<0.05). The proportion of cells in the G(0)/G(1) phase in the cell cycle increased, with AE expression [ (63.45±3.10) %) ] was higher than AE non-expression [ (41.36± 9.56) %] (P<0.05). The proportion of cells expressing CD13 and CD14 decreased with the expression of AE. The AE negative group is significantly higher than the AE positive group (P<0.05). ③The enrichment analysis of the transcriptome sequencing gene set revealed significantly enriched quiescence, nuclear factor kappa-light-chain-enhancer of activated B cells, interferon-α/γ, and other inflammatory response and immune regulation signals after AE expression. ④Disorder of fatty acid metabolism of U937-AE cells occurred under the influence of AE. The concentration of the medium and short-chain fatty acid acylcarnitine metabolites decreased in cells with AE expressing, propionyl L-carnitine, wherein those with AE expression (0.46±0.13) were lower than those with AE non-expression (1.00±0.27) (P<0.05). The metabolite concentration of some long-chain fatty acid acylcarnitine increased in cells with AE expressing tetradecanoyl carnitine, wherein those with AE expression (1.26±0.01) were higher than those with AE non-expression (1.00±0.05) (P<0.05) . Conclusion: This study successfully established a leukemia cell model that can induce AE expression. The AE expression blocked the cell cycle and inhibited cell differentiation. The gene sets related to the inflammatory reactions was significantly enriched in U937-AE cells that express AE, and fatty acid metabolism was disordered.

BACKGROUND: Psoriasis is a chronic inflammatory skin disease, affecting about 0.6% of the Chinese population. Many patients are not well controlled by conventional treatments, thus there is need for new treatment regimens. In this study, we assessed the efficacy and safety of secukinumab in Chinese patients with moderate to severe plaque psoriasis. METHODS: This study was a 52-week, multicentre, randomized, double-blind, placebo-controlled, parallel-group, Phase 3 trial. A sub-population of study participants (≥18 years) of Chinese ethnicity were randomized to receive subcutaneous injections of 300 or 150 mg secukinumab, or placebo. The co-primary endpoints were psoriasis area severity index (PASI) 75 and Investigator's Global Assessment (IGA) 0/1 at Week 12. RESULTS: A total of 441 Chinese patients were enrolled in this study. Co-primary outcomes were achieved; 300 and 150 mg secukinumab were superior to placebo as shown in the proportion of patients that achieved PASI 75 (97.7% and 87.2% vs. 3.7%, respectively; P < 0.001), and IGA 0/1 (82.3% and 69.7% vs. 2.7%; P < 0.001) at Week 12. Treatment efficacy was maintained until Week 52. There was no increase in overall adverse events with secukinumab relative to placebo throughout the 52-week period. CONCLUSION: Secukinumab is highly effective and well tolerated in Chinese patients with moderate to severe plaque psoriasis.

Objectives: To compare the changes in effectiveness of cross-institutional collaboration before and after intervention and non-intervention from medical personnel in order to empirically support promoting cross-institu-tional communication, coordination and cooperation modes for chronic diseases services. Methods: The typical sam-pling and multistage random sampling were used to conduct a questionnaire survey among medical personnel at villa-ges, townships and county levels. The Propensity ( Tendency) Scores were used to match the samples of the baseline and the following year of intervention, and the results were statistically analyzed. Results: After one-year of interven-tion, the county-level hospital doctors manifested higher participation while the sense of identity in work decreased;township medical personnel offered patient-centered provision of chronic disease services at higher level, but they re-ceived limited benefits from training attendance; and village medical institutions benefited a lot from the improved health care services and improved the clinic capability from cross-institutional collaboration on chronic diseases serv-ices. Suggestions: At the level of cross-institutional collaboration model policy development, attention should be paid on the work needs of county-level hospital doctors. It is also necessary to improve incentive mechanism and to work out definite and clear procedures and standards of promotion, establish a sound cross-institutional training mechanism and put knowledge into practice thereby encouraging individual development. For ultimate stand-straight, the roles and responsibilities of multi-level institutions in cross-institutional cooperation should be explored from the perspective of continuous chronic disease services.

OBJECTIVETo investigate the effects of serum procalcitonin(PCT) levels for predicting the outcome of bacteria bloodstream infection in acute leukemia patients.

METHODSClinical data from 236 patients with acute leukemia accompanied by bacterial bloodstream infection during July 2014 to November 2017 were retrospectively analyzed, 236 patients were divided into 5 groups (<0.05 ng/ml, 0.05- <0.5 ng/ml, 0.5- <2.0 ng/ml, 2.0- <10.0 ng/ml and >10.0 ng/ml) according to PCT concentrations.

RESULTSThe median age of patients was 40(13-73) years old. The male 123 cases(52.1%) and female 113 cases(47.9%) in 236 patients. The incidence of infection-related dealth in 5 groups was 0%, 1.4%, 13.8%, 25.0% and 33.3%, respectively; the incidence of septic shock and other serious complications in 5 groups was 0%, 2.1%, 13.8%, 25.0%, 33.3% and 6.4%, 7.0%, 24.1%, 41.7%, 50.0%, respectively, showing the concentration dependent manner and statistically significant difference (u=2127, P=0.000; u=2234, P=0.000; u=4102, P=0.000). Further analysis showed that with the increase of PCT concentration, the cumulative incidence of septic shock, infection-related death and other serious complications was gradually increased with statistically significance (HR=2.887, P=0.000, 95%CI:1.960-4.260; HR=3.158, P=0.000, 95%CI: 2.100-4.740; HR=2.158, P=0.000, 95%CI:1.550-3.000) respectively. Increased procalcitonin level is an independent risk factor for septic shock and infection-related death (HR=2.517, P=0.000, 95%CI: 1.520-4.168; HR=2.881, P=0.000, 95%CI: 1.692-4.904)respectively.

CONCLUSIONSerum procalcitonin level positively correlates with the incidence of serious bacteria bloodstream infection complications in the patients with acute leukemia. Increased procalcitonin level is an independent risk factor for septic shock and infection-related death, indicating that procalcitonin may be an important prognostic factor for infection outcome in acute leukemia patients with bacteremia.

Objective: To analyze the clinical and laboratory characteristics, and prognosis of adult acute myeloid leukemia (AML) patients with MLL gene rearrangements. Methods: The medical records of 92 adult AML patients with MLL gene rearrangements from January 2010 to December 2016 were retrospectively analyzed. Results: 92 cases (6.5%) with MLL gene rearrangements were identified in 1 417 adult AML (Non-M(3)) patients, the median age of the patients was 35.5 years (15 to 64 years old) with an equal sex ratio, the median WBC were 21.00(0.42-404.76)×10(9)/L, and 78 patients (84.8%) were acute monoblastic leukemia according to FAB classification. Eleven common partner genes were detected in 32 patients, 9 cases (28.1%) were MLL/AF9(+), 5 cases (15.6%) were MLL/AF6(+), 5 cases (15.6%) were MLL/ELL(+), 2 cases (6.3%) were MLL/AF10(+), 1 case (3.1%) was MLL/SETP6(+), and the remaining 10 patients' partner genes weren't identified. Of 92 patients, 83 cases with a median follow-up of 10.3 (0.3-74.0) months were included for the prognosis analysis, the complete remission (CR) rate was 85.5% (71/83), the median overall survival (OS) and relapse free survival (RFS) were 15.4 and 13.1 months, respectively. Two-year OS and RFS were 36.6% and 29.5%, respectively. Of 31 patients underwent allogeneic hematopoietic stem-cell transplantation (allo-HSCT), two-year OS and RFS for patients received and non-received allo-HSCT were 57.9% and 21.4%, 52.7% and 14.9%, respectively (P<0.001). Among patients with partner genes tested, 9 of 32 cases (28.1%) were MLL/AF9(+), the median follow-up was 6.0(4.1-20.7) months. 3 patients with MLL/AF9 underwent allo-HSCT. 23 cases (71.9%) were non- MLL/AF9(+), the median follow-up was 7.8 (0.3-26.6) months. 14 patients (60.1%) with non-MLL/AF9 underwent allo-HSCT. One-year OS for patients with MLL/AF9 and non-MLL/AF9 were 38.1% and 55.5%, respectively (P=0.688). Multivariate analysis revealed that high WBC (RR=1.825, 95% CI 1.022-3.259, P=0.042), one cycle to achieve CR (RR=0.130, 95% CI 0.063-0.267, P<0.001), post-remission treatment with allo-HSCT (RR=0.169, 95% CI 0.079-0.362, P<0.001) were independent prognostic factors affecting OS. Conclusions: AML with MLL gene rearrangements was closely associated with monocytic differentiation, and MLL/AF9 was the most frequent partner gene. Conventional chemotherapy produced a high response rate, but likely to relapse, allo-HSCT may have the potential to further improve the prognosis of this group of patients.

OBJECTIVETo investigate the incidence of karyotypes and gene mutations for elder acute myeloid leukemia and to explore the relationship between each other.

METHODSClinical data and bone marrow samples of elder AML patients were collected. Karyotype and gene mutation (FLT3, NPM1, C-Kit, CEBPα, DNMT3A) test were performed, characteristics of karyotypes and gene mutations were analysed.

RESULTSThe incidence of better risk karyotype was 16.6%, in which the incidences of t(15;17), t(8;21) and inv (16)/t(16;16) were 3.90%, 10.73%, and 1.95% respectively; the incidence of intermediate risk karyotype was 72.2%, in which the incidence of normal karyotype was 57.86%; the incidence of poor risk karyotype was 11.20%, in which the incidence of of MLL/11q23, complex karyotype and monosomal karyotype were 1.95%, 6.34%, 5.85% respectively; the incidences of FLT3, NPM1, C-Kit, CEBPα, DNMT3A mutation were 12.57%, 22.06%, 2.16%, 14.71%, 15.71% respectively. Compared with patients older than 60 years, patients with age of 55-60 years were with less complex karyotype (1.09% vs 10.62%)(P=0.003) and monosomal karyotype (2.17% vs 8.85%)(P=0.032), and more t(8;21)(17.39% vs 5.31%)(P=0.008) and inv (16)/t(16;16)(4.35% vs 0.00%)(P=0.045).

CONCLUSIONFor older AML patients, great difference in the distribution of karyotyes was found between the patients older than 60 years and patients with age of 55-60 years, while no such characteristics was found for gene mutations. Good elucidation of karyotypes and gene mutations are key for the treatment of older acute myeloid leukemia patients.

OBJECTIVETo evaluate the accuracy of marginal and internal fit of the zirconium copings manufactured by two different computer-aided design(CAD)/computer-aided manufacturing(CAM)system on the implant abutment.

METHODSUsing different scanning mode,five Procera(®) zirconium copings and five Lava zirconium copings were fabricated on the same implant abutment, and then compared with five precious metal copings fabricated by traditional method. Fifteen abutment replica were made with die-stone and the copings were randomly cemented on them, then they were sectioned and invested. The marginal, shoulder, occlusal, and axial fit of each sample was measured by scanning electron microscopy (SEM).

RESULTSThere was no significant difference in marginal and axial fit among the three groups(P>0.05). Significant difference in occlusal fit was found among the three groups(P<0.05): Lava group showed better fit than the others(P<0.05)and Procera(®) group showed better fit than the control(P<0.05).

CONCLUSIONSThese two types of zirconium coping have clinically acceptable marginal and internal fit. The internal fit of zirconium coping may be affected by different manufacturing techniques.

OBJECTIVETo investigate the effect of dihydrotestosterone (DHT) on the gene transcriptions and expressions of Smad3 and Smad4 in androgen dependent prostate cancer cell line LNCaP, and whether this effect can be suppressed by the androgen receptor inhibitor flutamide.

METHODSThe androgen dependent prostate cancer cell line LNCaP was cultured in RPMI 1640 medium and treated with different concentrations of DHT(2, 10, 50 nmol/L) and flutamide (100 nmol/L). Quantitative reverse transcription PCR (RT-PCR) was used to detect the mRNAs of Smad3 and Smad4. The expressions of Smad3 and Smad4 protein were detected by Western blot assay.

RESULTSCompared with the control group without any DHT or flutamide, higher concentration(10, 50 nmol/L) of DHT enhanced the transcription of Smad3 mRNA (P <0.05). Serial concentrations of DHT increased the expression of Smad3 protein(P < 0.05). Flutamide inhibited the up-regulation of both Smad3 mRNA transcription and expression significantly (P <0.05). 10 nmol/L DHT significantly suppressed the transcription of Smad4 (P <0.05). There was considerable suppressions of Smad4 expression at the presence of DHT in different concentrations (P < 0.05). And the degree of this suppression was more significant than that of DHT on Smad4 mRNA transcription. Flutamide inhibited the suppressive effects of DHT on both Smad4 mRNA transcription and expression.

CONCLUSIONDHT can enhance the transcription and expression of Smad3, while it decreases the transcription and expression of Smad4 in LNCaP cell line. There is a possible crosstalk between the AR signal and TGF-beta signal passways at the level of Smads.
