BACKGROUND: Evidence on the relations of the American Heart Association's ideal cardiovascular health (ICH) with mortality in Asians is sparse, and the interaction between behavioral and medical metrics remained unclear. We aimed to fill the gaps. METHODS: A total of 198,164 participants without cancer and cardiovascular disease (CVD) were included from the China Kadoorie Biobank study (2004-2018), Dongfeng-Tongji cohort (2008-2018), and Kailuan study (2006-2019). Four behaviors (i.e., smoking, physical activity, diet, body mass index) and three medical factors (i.e., blood pressure, blood glucose, and blood lipid) were classified into poor, intermediate, and ideal levels (0, 1, and 2 points), which constituted 8-point behavioral, 6-point medical, and 14-point ICH scores. Results of Cox regression from three cohorts were pooled using random-effects models of meta-analysis. RESULTS: During about 2 million person-years, 20,176 deaths were recorded. After controlling for demographic characteristics and alcohol drinking, hazard ratios (95% confidence intervals) comparing ICH scores of 10-14 vs. 0-6 were 0.52 (0.41-0.67), 0.44 (0.37-0.53), 0.54 (0.45-0.66), and 0.86 (0.64-1.14) for all-cause, CVD, respiratory, and cancer mortality. A higher behavioral or medical score was independently associated with lower all-cause and CVD mortality among the total population and populations with different levels of behavioral or medical health equally, and no interaction was observed. CONCLUSIONS ICH was associated with lower all-cause, CVD, and respiratory mortality among Chinese adults. Both behavioral and medical health should be improved to prevent premature deaths.

With the advance of the economy and population aging, the acceleration of urbanization and the change of people's lifestyles, the prevalence of chronic diseases has become very serious. However, the etiologies and pathogeneses of the diseases are not yet clear, and the evidence of effective prevention and treatment strategies is lacking. Cohort study is an important method for exploring etiology and pathogenesis. Therefore, based on the support of the Ministry of Science and Technology for precision medicine in 2016, we launched a prospective cohort study of common chronic and non-communicable diseases in three provinces (Hubei, Hunan and Henan) in central China. Three independent and integratable sub-cohorts consisting of 115 424 participants at baseline survey and 107 252 participants in follow up were established, including dynamic measurements in 39 000 subjects in Dongfeng-Tongji prospective cohort. Each participant was asked to complete a questionnaire survey, an anthropometric measurement, a laboratory measurement, and blood and urine samples were collected from them. The cohort study contributes greatly to elucidating the etiologies and pathogeneses of common chronic and non-communicable disease in Chinese population and the development of precision medicine in China. This paper briefly introduces the design concept, basic information, major achievements and progress, and challenges of the prospective cohort study of common chronic and non-communicable diseases in central China.

Purpose: Precise estimation of the standard liver volume (SLV) is crucial in decision making regarding major hepatectomy and living donor liver transplantation. This study aimed to propose an accurate and efficient formula for estimating the SLV in the Korean population. Methods: We created a regression model for SLV estimation using a data set of 230 Korean patients with healthy livers. The proposed model was cross validated using a different data set of 37 patients with healthy livers. The total liver volume (TLV), except for the volume of liver blood vessels, was measured through computed tomography volumetry as the dependent variable. Various anthropometric variables, liver height (LH), thoracic width (TW), age, and sex (0, female and 1, male) were considered as candidates for independent variables. We conducted stepwise regression analysis to identify variables to be included in the proposed model. Results: A new formula was established; SLV = −1,275 + 9.85 × body weight (BW, kg) + 19.95 × TW (cm) + 7.401 × LH (mm). The proposed formula showed the best performance among existing formulas over the cross-validation data set. Conclusion The proposed formula derived using BW, TW, and LH estimated the TLV in the cross-validation data set more accurately than existing formulas.f

Objective: To explore the relationship between anthropometric indices and the incident risk of hypertension, compare novel anthropometric indices with traditional indices in hypertension prediction and establish hypertension prediction models among elderly Chinese. Methods: A total of 27 009 retirees from the Dongfeng Motor Corporation were recruited at baseline in 2008 and the first follow-up was conducted in 2013. After the exclusion of participants less than 60 years old, participants with hypertension, coronary heart disease, stroke, cancer, and those with missing data, a total of 6 784 elderly participants were enrolled in this study. A multivariate logistic regression model was used to analyze the relationship between traditional anthropometric indices, body mass index (BMI), waist circumference (WC), waist-to-height ratio (WHtR), novel anthropometric indices, visceral adiposity index (VAI), body shape index (ABSI), body roundness index (BRI), and the incident risk of hypertension. Meanwhile, a multivariate logistic regression model was used to establish hypertension prediction models. Receiver operating characteristic (ROC) curve was applied to compare the prediction ability of different models. Results: A total of 1 787 incident cases of hypertension were identified, with the incidence of hypertension about 27.59%. Significant positive associations were detected between BMI, WC, WHtR, VAI, BRI and the incident risk of hypertension after adjusting for potential confounders (all P values<0.05). In men, the OR (95%CI) (upper tertile vs lower tertile) was 1.45 (1.22-1.73) for VAI, and 1.86 (1.55-2.23) for BRI. In women, the OR (95% CI) (upper tertile vs lower tertile) was 1.55 (1.22-1.96) for VAI, and 1.60 (1.27-2.01) for BRI. For ABSI, no significant association was observed in either men (OR (95%CI): 1.07 (0.90-1.28)) or women (OR (95%CI): 1.03 (0.82-1.29), both P values >0.05). The basic hypertension prediction model included age, drinking (only in men), education status (only in men), systolic blood pressure (SBP), diastolic blood pressure (DBP), and fasting blood glucose levels. Based on the basic prediction model, BMI (in men: AUC=0.697) and BRI (only in men: AUC=0.696) improved area under ROC curve (AUC) significantly (P<0.05). BMI was the strongest predictor in both men (AUC=0.697) and women (AUC=0.685) in the extended model. Conclusion Significant positive associations were detected between BMI, WC, WHtR, VAI, BRI and the incident risk of hypertension among elderly Chinese. BMI was the strongest predictor in hypertension prediction model compared with other anthropometric indices.

Objective To study the antitumor activity of Xerophilusin G on S180 cells,and Its mechanism.Methods Modified MTT assay was used to test the effect of Xerophilusin G on the proliferation of S180 tumor cell strain.The influences on tumor growth and immune organs of mice with transplanted sarcoma (S180) were observed.The cell cycle of S180 cell lines and mouse sarcoma (S180) was analyzed by flow cytometry.The lymphocyte proliferation activity of spleen stimulating was tested.The level of IL-2 in serum of mice with transplanted sarcoma (S180) was measured by ELISA.Results The IC50 of Xerophilusin G in S180 cell lines was 19.80 μg·mL-1,the LD50 in mouse for Xerophilusin G was 121.11 mg·kg-1 through intraperitoneal injection.The tumor inhibition rate of Xerophilusin G was 32.11％ and 41.60％,respectively at the doses of 3 and 6 mg · kg-1 (P ＜ 0.05).Compared with the control,the thymus,kidney and cardiac index were decreased.The cell proportion at G0/G1 phase of mouse sarcoma (S180) was increased.T and B cell proliferation activities in tumor-bearing mice were enhanced (P ＜ 0.05).As compared with control group,the serum level of IL-2 was decreased 90.9％ and 77.1％ in low-and medium-dose groups,respectively (P ＜ 0.05).Conclusion Xerophilusin G has remarkable effects in sarcoma (S180) bearing mice.The antitumor mechanism of Xerophilusin G might be related with G0/G1 phase arrest of mouse sarcoma (S180) cells and enhancing the activity of T and B cell but not related with increasing the secreting of IL-2.

Objective To monitor the level of urinary iodine in pregnant women in Xiaogan area,to understand the iodine nutri-tional status of pregnant women during pregnancy,and to provide theoretical basis for scientific guidance of iodine intake in preg-nant women.Methods The urine iodine levels of 2 956 pregnant women in Xiaogan Hospital Affiliated to Wuhan University of Sci-ence and Technology from March 2016 to May 2017 were examined and analyzed.Results In Xiaogan area,the median concentra-tions of urinary iodine in the early,middle and late stages of pregnant women were 145.73 μg/L,176.88 μg/L and 170.37 μg/L. 996 pregnant women were with urinary iodine concentration of over 150 μg/L,accounting for 33.69%;1372 pregnant women were with urinary iodine concentration of 150-249 μg/L,accounting for 46.41%;556 pregnant women were with urinary iodine concen-tration of 250-499 μg/L,accounting for 18.81%;32 pregnant women were with urinary iodine concentration of over 500 μg/L,ac-counting for 1.08%.The incidence rates of iodine deficiency in pregnant women at early,middle and late stage were 42.86%, 32.95% and 40.00%,and the difference was statistically significant(P<0.05).The incidence rate of iodine deficiency was 32.33%in pregnant women with age ≤ 30 years old,the incidence of iodine deficiency was 36.89% in pregnant women with age > 30 years old,and the difference was statistically significant(P<0.05).Conclusion At this stage,in Xiaogan,there are no overall maternal i-odine deficiency,but there was iodine malnutrition in pregnant women in early pregnancy,and some pregnant women lack awareness of iodine.

Objective To compare the clinical characters and hemodynamic data of the prone position and supine position percutaneous nephrolithotomy. Methods Patients with kidney stones in 100 cases were randomly assigned into the supine position group and prone position group.There were 50 cases in each group.The following data were recorded at preoperative,intraoperative,change position:the blood pressure,heart rate,respiration,saturation of blood oxygen and blood gas analysis results.The VAS score was recorded in patients for postural comfort,dyspnea and pain score. Results The systolic blood pressure in the preoperative,intraoperative,postoperative on supine position and prone position were as follows:(137±12),(119±15),(115±17) mm Hg and (137±10),(110±18),(104±16) mmHg.The diastalic blood pressure was as follows:( 81 ± 9 ),(74 ± 8 ),(63 ± 14 ) mm Hg and ( 84 ± 8 ),(63 ± 9 ),(60 ± 15) mm Hg.Compared with preoperative,there was a blood pressure decreased in both groups.The blood pH at preoperative,intraoperative,postoperative in supine position and prone position:7.4 ± 0,7.3 ± 0,7.3 ± 0 and 7.4 ± 0,7.3 ± 0,7.3 ± 0.The bass excess (BE) of two groups were:(2.1 ± 0.5),(-2.7 ±0.5),( -1.5 ±0.5) mmol/L and (3.2 ±0.5),(-3.8 ±0.5),(-2.5 ±0.5) mmol/L.Compared with preoperative data,the pH and BE declined in both groups.The prone position had more pronounced decrease in serum sodium,serum potassium; but with no significant difference.Supine group in postural comfort and breathing difficulties were 1.6 ± 0.4 and 7.1 4± 05,while prone group were 7.5 ± 0.2 and 1.4 ± 0.3.The supine position showed better in postural comfort and breathing difficulties with statistical significance. Conclusions Compared with the prone position,the supine positioned percutaneous nephrolithotomy could have less influence on hemodynamics,blood gas analysis.It could have better postural comfort.

Pim kinases contribute to tumor formation and development of lymphoma, which shows enhanced DNA replication, DNA recombination and repair. Endothelial cells^(ECs) express all the three members of Pim kinase gene family. We hypothesized that DNA repair gene would regulate Pim expression in ECs. Human umbilical vein endothelial cells (HUVECs) were isolated and maintained in M199 culture medium. The cellular distribution of Pim-3 in ECs was determined by immunofluorescent staining. The siRNA fragments were synthesized and transfected by using Lipofectamine LTX. The total cellular RNA was extracted from the cells by using Trizol reagent. cDNAs were quantified by semi-quantity PCR. The effects of LY294002 and wortmannin on RNA stability in ECs were also examined. Our data showed that LY294002 and wortmannin, phosphatidylinositol 3-kinase (PI3K) and PI3K-like kinase inhibitors, increased Pim mRNA expression in ECs without altering the mRNA stability. RNA interference (RNAi) targeting DNA-dependent protein kinase catalytic subunit (DNA-PKcs) and ataxia telangiectasia mutated (ATM) increased mRNA expression of Pim-3 and Pim-1, respectively. Silencing of Akt decreased Pim-1 instead of Pm-2 and Pim-3 gene expression in ECs. But etoposide, a nucleoside analogue, which could activate DNA-PKcs and ATM, increased Pim expression in ECs. Our study indicates that the expression of Pim kinases is physiologically related to DNA-PKcs and ATM in ECs.

Objective To investigate the safety and efficacy of percutaneous nephrolithotomy (PCNL) in a new operative position, flank suspended supine position. Methods The new position hold affected flank suspended by raising the ipsilateral shoulder and haunch with two 3-liter saline bags, and set up waist bridge simultaneously. From March 2010 to October 2010, a series of 173 patients underwent PCNL with the new supine position under epidural anesthesia. The average age was (50± 11) years, and the average bulk of the stone was (2. 9±1.0) cm. All patients were placed in the new supine position. Under ultrasound guidance, the desired calix or pelvis was punctured near the posterior axillary line, then dilating the tract and establishing the 16 F or 20 F tract for PCNL. Results The pelvicaliceal system could be successfully approached in all patients. The procedure was well tolerated in all patients. Mean operation time was (86 ± 34) min. 80. 3% of the patients were rendered free of stones by the initial PCNL. Thirty-four cases had residual stones, and a second PCNL was performed in 16 cases to clear the residual stones. Only 1 patient required blood transfusion.None of the patients suffered visceral injury. Conclusion The new supine position is safe and effective for PCNL.
