Abstract
Objective: To evaluate the safety of early enteral nutrition (EEN) support in patients with severe intra-abdominal infection and intestinal fistulas. Methods: This was a retrospective cohort study. We collected relevant clinical data of 204 patients with severe intra-abdominal infection and intestinal fistulas who had been managed in the No. 1 Department of General Surgery, Shanghai Ninth People's Hospital, Shanghai Jiaotong University between 1 January 2017 and 1 January 2020. The patients were allocated to EEN or delayed enteral nutrition (DEN) groups depending on whether enteral nutrition had been instituted within 48 hours of admission to the intensive care unit. The primary outcome was 180-day mortality. Other outcomes included rates of intraperitoneal hemorrhage, septic shock, open abdominal cavity, bloodstream infection, mechanical ventilation, and continuous renal replacement therapy. Risk factors for mortality were analyzed by logistic regression. Results: There were no significant differences in hematological data or other baseline characteristics between the two groups at the time of admission to the intensive care unit (all P>0.05). However, septic shock (31.2% [15/48] vs. 15.4% [24/156], χ2=4.99, P=0.025), continuous renal replacement therapy (27.1% [13/48] versus 9.0% [14/156], χ2=8.96, P=0.003), and 180-day mortality (31.2% [15/48] vs. 7.7% [12/156], χ2=15.75, P<0.001) were significantly more frequent in the EEN than the DEN group (all P<0.05). Multivariate regression analysis showed that older age (OR=1.082, 95%CI:1.027-1.139,P=0.003), worse Acute Physiology and Chronic Health Evaluation (APACHE) II scores (OR=1.189, 95%CI: 1.037-1.363, P=0.013), higher C-reactive protein (OR=1.013, 95%CI:1.004-1.023, P=0.007) and EEN (OR=8.844, 95%CI:1.809- 43.240, P=0.007) were independent risk factors for death in patients with severe intra-abdominal infection and intestinal fistulas. Conclusion: EEN may lead to adverse events and increase mortality in patients with both enterocutaneous fistulas and severe abdominal infection. EEN should be implemented with caution in such patients.

Abstract
Objective: To estimate the risk for type 2 diabetes mellitus (T2DM) death attributed to insufficient whole grain intake in seven regions of China from 2005 to 2018. Methods: Based on China National Nutrition and Health Surveys and China Adult Chronic Disease and Nutrition Surveillance, ordinary Kriging method and locally weighted regression were used to estimate the level of whole grain intake of Chinese residents from 2005 to 2018. Based on the results of the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019 and Chronic Diseases Risk Factors Surveillance in China, we calculated the population attributable fraction (PAF), attributable death number and attributable mortality rate of T2DM due to insufficient whole grain intake in people aged ≥20 years in different regions of China, and we used the 2010 Chinese census data to compare the changes in T2DM deaths attributed to insufficient intake of whole grains in seven regions of China. Results: The whole grain intake levels of Chinese people over 20 years old in 2002, 2010 and 2015 were 19.0 g/d, 14.3 g/d and 19.8 g/d, respectively. The estimated overall whole grain intake level was 20.1 g/d in Chinese residents in 2018, and the intake level was 19.4 g/d in men and 20.8 g/d in women. Among the seven regions, the intake level was highest in northern China (47.4 g/d) and lowest in southwestern China (6.0 g/d). In 2018, the PAF was lowest in northern China (12.8%) and highest in southwestern China (19.3%). From 2005 to 2018, the PAF varied in the seven regions, and the PAF in northeastern China fluctuated around 18.5%. Other regions showed downward trends, especially in northern China and northwestern China, decreased by 26.4% and 21.2%, respectively. Over the past 14 years, the number of attributable deaths in the seven regions showed upward trends, with the highest annual average growth rate of 6.7% in southern China and the lowest annual average growth rate of 2.4% in northern China. In 2018, the standardized T2DM mortality rate attributed to insufficient whole grain intake in China was 3.13/100 000, and the attributable mortality was 3.21/100 000 in men and 3.05/100 000 in women. The standardized attributable mortality rate was highest in southwestern China (3.97/100 000) and lowest in northern China (1.78/100 000). From 2005 to 2018, the standardized attributable mortality rate increased by 11.5% in men and decreased by 8.1% in women. The standardized attributable mortality rate in southwestern, southern and central China increased by 23.7%, 21.3% and 4.2%, respectively. The standardized attributable mortality rate in northern, northwestern, eastern and northeastern China decreased by 20.9%, 11.0%, 4.5% and 3.9%, respectively. Conclusion: The whole grain intake level of Chinese residents was low, and the whole grain intake of residents in all seven regions should be increased, especially in the southwest, and men should have more whole grain intake than women to reduce the death risk in patients with T2DM.

Abstract
Objective: To describe the prevalence of alcohol consumption and the burden of hemorrhagic stroke and hypertensive heart disease attributed to alcohol consumption in adults aged ≥20 years in 31 provinces in China from 2005 to 2018. Methods: Data from several national representative surveys was used to estimate provincial alcohol exposure level of adults aged ≥20 years from 2005 to 2018 by using kriging interpolation and locally weighted regression methods. Global disease burden research method and data, and China's death cause surveillance data were used to calculate the population attributable fraction (PAF) of hemorrhagic stroke and hypertensive heart disease and the deaths due to alcohol consumption in men and women aged ≥20 years in 31 provinces in China. China census data of 2010 were used to calculate the attributable standardized mortality rate. Results: In 2005 and 2018, the prevalence of alcohol consumption was 58.7% (95%CI: 57.8%-59.5%) and 58.4% (95%CI: 57.6%-59.3%), respectively, in men and 17.0% (95%CI: 16.6%-17.4%) and 18.7% (95%CI:18.1%-19.3%), respectively, in women. The daily alcohol intake was 24.6 (95%CI: 23.8-25.3) g and 27.7 (95%CI: 26.8-28.7) g, respectively, in men and 6.3 (95%CI: 6.0-6.5) g and 5.3 (95%CI: 5.0-5.6) g, respectively, in women. Alcohol exposure level was higher in the provinces in central and eastern China than in western provinces. The lowest exposure level was found in northwestern provinces. From 2005 to 2018, the PAF of hemorrhagic stroke death due to alcohol consumption increased from 5.5% to 6.8%, the attributable deaths increased from 50 200 to 59 100, while the PAF of hypertensive heart disease death due to alcohol consumption increased from 7.0% to 7.7%, the attributable deaths increased from 15 200 to 29 300. The PAF of hypertensive heart disease and hemorrhagic stroke was higher in men than in women, and in central and eastern provinces than in western provinces. In 2018, the standardized mortality rates of hemorrhagic stroke and hypertensive heart disease attributed to alcohol consumption were 4.58/100 000 and 2.11/100 000, respectively. Conclusions: The prevalence of alcohol consumption in men and daily alcohol intake of drinkers were relatively high in China, especially in eastern provinces. Alcohol exposure level was lower in women than in men. Regional measures should be taken to reduce the alcohol intakes in men and current drinkers in order to reduce the health problems caused by alcohol consumption.

Abstract
Nitrate allocation in Arabidopsis (Arabidopsis thaliana) represents an important mechanism for mediating plant environmental adaptation. However, whether this mechanism occurs or has any physiological/agronomic importance in the ammoniphilic plant rice (Oriza sativa L.) remains unknown. Here, we address this question through functional characterization of the Nitrate transporter 1/Peptide transporter Family (NPF) transporter gene OsNPF7.9. Ectopic expression of OsNPF7.9 in Xenopus oocytes revealed that the gene encodes a low-affinity nitrate transporter. Histochemical and in-situ hybridization assays showed that OsNPF7.9 expresses preferentially in xylem parenchyma cells of vasculature tissues. Transient expression assays indicated that OsNPF7.9 localizes to the plasma membrane. Nitrate allocation from roots to shoots was essentially decreased in osnpf7.9 mutants. Biomass, grain yield, and nitrogen use efficiency (NUE) decreased in the mutant dependent on nitrate availability. Further analysis demonstrated that nitrate allocation mediated by OsNPF7.9 is essential for balancing rice growth and stress tolerance. Moreover, our research identified an indica-japonica divergent single-nucleotide polymorphism occurring in the coding region of OsNPF7.9, which correlates with enhanced nitrate allocation to shoots of indica rice, revealing that divergent nitrate allocation might represent an important component contributing to the divergent NUE between indica and japonica subspecies and was likely selected as a favorable trait during rice breeding.

Abstract
BACKGROUND Even mild renal disease is a powerful cardiovascular risk factor. However, the association between these pathophysiologic processes (especially in the early asymptomatic stage) is not known. METHODS We recruited 243 asymptomatic patients with Stages 1-4 chronic kidney disease (CKD) without obstructive coronary artery disease (CAD). We distinguished different degrees of severity of intrarenal arterial lesions (IALs) according to the Oxford classification. Myocardial microcirculation perfusion was measured using single-photon emission computed tomography (SPECT). Summed scores of 17 stress and rest image segments produced the summed stress score (SSS) and summed rest score (SRS), respectively. The summed difference score (SDS) was calculated as the difference between the SSS and SRS. Coronary microvascular disease (CMD) was defined as abnormal SPECT (SSS ≥4 or SDS ≥2) in the absence of obstructive CAD. RESULTS Participants showed a stepwise increase in CMD severity with IAL aggravation. SSS of no/mild/moderate/severe IALs was 1.64 ± 1.08, 2.56 ± 1.35, 4.42 ± 2.17 and 6.48 ± 3.52, respectively (P < 0.05 for all). SDS of no/mild/moderate/severe IALs was 1.29 ± 0.49, 1.75 ± 0.56, 3.06 ± 1.12 and 4.16 ± 1.85, respectively (P < 0.05 for all). The percentage of subclinical CMD in CKD patients with IALs was significantly higher than in those without IALs (69.57% versus 14.71%; P = 0.01). Multiple regression analysis showed that renal arteriolar hyalinization (odds ratio = 1.578, P = 0.009) was associated independently with subclinical CMD. CONCLUSIONS We demonstrated, for the first time, that impaired perfusion in the myocardial microcirculation in asymptomatic patients with Stages 1-4 CKD with IALs. Renal arteriolar hyalinization may be a useful marker of CMD in CKD.

Abstract
BACKGROUND Shenyankangfu Tablet (SYKFT) is a Chinese patent medicine that has been used widely to decrease proteinuria and the progression of chronic kidney disease. OBJECTIVE This trial compared the efficacy and safety of SYKFT, for the control of proteinuria in primary glomerulonephritis patients, against the standard drug, losartan potassium. DESIGN, SETTING, PARTICIPANTS AND INTERVENTION This was a multicenter, double-blind, randomized, controlled clinical trial. Primary glomerulonephritis patients, aged 18-70 years, with blood pressure ≤ 140/90 mmHg, estimated glomerular filtration rate (eGFR) ≥ 45 mL/min per 1.73 m2, and 24-hour proteinuria level of 0.5-3.0 g, were recruited in 41 hospitals across 19 provinces in China and were randomly divided into five groups: SYKFT, losartan potassium 50 mg or 100 mg, SYKFT plus losartan potassium 50 mg or 100 mg. MAIN OUTCOME MEASURES The primary outcome was change in the 24-hour proteinuria level, after 48 weeks of treatment. RESULTS A total of 735 participants were enrolled. The percent decline of urine protein quantification in the SYKFT group after 48 weeks was 8.78% ± 2.56% (P = 0.006) more than that in the losartan 50 mg group, which was 0.51% ± 2.54% (P = 1.000) less than that in the losartan 100 mg group. Compared with the losartan potassium 50 mg group, the SYKFT plus losartan potassium 50 mg group had a 13.39% ± 2.49% (P < 0.001) greater reduction in urine protein level. Compared with the losartan potassium 100 mg group, the SYKFT plus losartan potassium 100 mg group had a 9.77% ± 2.52% (P = 0.001) greater reduction in urine protein. With a superiority threshold of 15%, neither was statistically significant. eGFR, serum creatinine and serum albumin from the baseline did not change statistically significant. The average change in TCM syndrome score between the patients who took SYKFT (-3.00 [-6.00, -2.00]) and who did not take SYKFT (-2.00 [-5.00, 0]) was statistically significant (P = 0.003). No obvious adverse reactions were observed in any group. CONCLUSION SYKFT decreased the proteinuria and improved the TCM syndrome scores of primary glomerulonephritis patients, with no change in the rate of decrease in the eGFR. SYKFT plus losartan potassium therapy decreased proteinuria more than losartan potassium therapy alone. TRIAL REGISTRATION NUMBER NCT02063100 on ClinicalTrials.gov.

Abstract
Objective: To establish Chinese diet balance index for preschool children(DBI_C), and evaluate the dietary quality of Chinese preschool children. Methods: DBI_C was established according to the methods establishing DBI_16 and the recommended intake of different kinds of food for preschool children. Three scoring methods [low bound score (LBS), high bound score (HBS), diet quality distance (DQD)] were used to evaluate the dietary quality of preschool children selected from the 2010-2012 China National Nutrition and Health Surveillance. Scores [P50(P25, P75)] were compared to reflect the diet quality of preschool children in different regions. Results: DBI_C scores for cereals of preschool children from big city, middle and small city, normal rural area, and poor rural area were 0.0 (-2.0, 6.0), 0.0 (0.0, 6.0), 4.0 (0.0, 10.0), and 10.0 (2.0, 12.0), respectively (P<0.001), indicating that the intakes of cereals of preschool children were adequate. Scores for animal food of preschool children from four types of location were 0.0 (-2.0, 2.0), 0.0 (-6.0, 2.0), -4.0 (-6.0, 0.0), and -6.0 (-8.0,-2.0), respectively (P<0.001), indicating that the intakes of animal food of rural preschool children were inadequate. Scores for vegetable and fruit, milk and soybean were both less than 0 (P<0.001), indicating that the intakes of these food were insufficient in both urban and rural area. Scores of LBS, HBS and DQD were 24.0 (18.0, 30.0), 8.0 (3.0, 13.0) and 33.0(26.0, 39.0). Children without diet insufficient problem in four type of location accounted for 30.8%, 7.8%, 4.3% and 1.1%, respectively (P<0.001). Children without diet excessive problem accounted for 54.0%, 57.3%, 52.9% and 32.6%, respectively (P<0.001). Children without diet imbalance problem were 10.6%, 1.1%, 1.3% and 0.3%, respectively (P<0.001). Conclusion: Diet quality of urban preschool children is better than that of rural preschool children. Dietary imbalance is the main problem among Chinese preschool children.

Abstract
Due to the flaws inherited in synchronicity, statistical association and survivor bias on variables under measurement, a common 'consensus' has been reached on "cross-sectiional studies (CSS) can lead to failure on causal inference". In this paper, under both causal thinking and diagram, the real and measured cross-sections are clearly defined that these two concepts only exist theoretically. In real CSS research, the temporal orders of measured variables are all non-synchronic, equivalent to the assumption that measurement variables are independent to each other, or there is no differentiated classification bias. Similar to cumulative case-control or historical cohort studies, both exposure and outcome that exist or occur before their measurements in cross-sectional studies, are actions of historical reconstruction or doing 'Archaeology'. One of the common preconditions for causal inference in such studies is that: there must be a causal relation between the measured variables and their historical counterparts. The measured variables are all agents of their corresponding real counterparts, and the temporal orders are not that important in causal inference. It is necessary to better understand the analytic role of the CSS.

Abstract
Objective: To investigate the drinking status and associated factors in adults in China. Methods: Based on the 2010-2012 China National Nutrition and Health Survey (CNNHS), a total of 135 824 participants aged ≥18 were included in this cross-sectional analysis. Multivariable logistic regression model was used to investigate the associated factors for drinking status. Results: The overall drinking rate was 30.5% in Chinese adults, 53.8% in men, and 12.2% in women. The excessive drinking rate was 14.0% in men and 1.1% in women. The daily drinking rate was 25.7% in men and 10.9% in women. Men mainly consumed multi-type wines, but women preferred beer. The overall harmful drinking rate was 7.1%. The excessive drinking rate, daily drinking rate, and harmful drinking rate increased first but then declined with age. All the four rates were positively related with physical activity. Conclusions: The drinking rate, excessive drinking rate, daily drinking rate and harmful drinking rate were high in adults in China. Drinking status was associated with age, sex, marital status, education level, smoking status and physical activity.

Abstract
Objective: To understand the prevalence of alcohol drinking and influencing factors in female adults in China. Methods: At the 150 survey sites where 2010-2012 Chinese nutrition and health surveillance was conducted, a face to face questionnaire survey was conducted in female adults selected through multi-stage stratified cluster random sampling. Sample weights was assigned to each participant based on the study design by using national population census data in 2009. The complex sampling and unconditional multivariate logistics regression analysis was conducted to identify the influencing factors for the prevalence of alcohol drinking in the female adults. Results: A total of 75 518 participants were included in this study. The prevalence of drinking in female adults was 13.9% (95%CI: 11.7-16.2) in urban area and 13.3% (95%CI: 9.4-17.2) in rural area. The prevalence of frequent drinking was 13.9% (95%CI: 9.9-17.9) in women in urban area and 14.2% (95%CI: 10.8-17.6) in women in rural area. The prevalence of excessive drinking was 11.1% (95%CI: 7.5-14.8) in women in urban area and 12.8% (95%CI: 9.1-16.4) in women in rural area. The prevalence of wine drinking in women in urban area was significantly higher than in women in rural and had positive correlation with income and education levels. The social and economic factors influencing drinking behavior of the female adults included occupation, drinking behaviors of family members and smoking behavior. Those who were engaged in agriculture, production and transportation (OR=0.72, 95%CI: 0.56-0.94, P=0.016), housework (OR=0.59, 95%CI: 0.44-0.78, P<0.001) and other work (OR=0.61, 95%CI: 0.43-0.85, P=0.004) had lower drinking prevalence. Whereas those whose family members had drinking behavior (OR=2.66, 95%CI: 2.17-3.26, P<0.001) and those who were current smokers (OR=4.32, 95%CI: 2.95-6.34, P<0.01) had higher drinking prevalence. Conclusions: The prevalence of drinking, frequent alcohol drinking and excessive drinking were relatively low in female adults in China. Occupation, drinking behaviors of family members and smoking behavior were the main factors influencing the prevalence drinking behavior in female adults in China.

Abstract
Background: Automated peritoneal dialysis (APD) can cater to individual needs, provide treatment while asleep, take into account the adequacy of dialysis, and improve the quality of life. Currently, independent research and development of APD machines made in China are more conducive to patients. A randomized, multicenter, crossover study was conducted by comparing an APD machine made in China with an imported machine. The safety, effectiveness, and manipulability of the two machines were compared. Methods: Two hundred and sixty patients who underwent peritoneal dialysis (PD) on a regular basis in 18 centers between August 2015 and February 2016 were included. The inclusion criteria include age ≥18 years and PD ≥30 days. The exclusion criteria were as follows: hemodialysis; exit site or tunnel infection; and peritonitis ≤30 days. The patients were randomly divided into Group A, who were first treated with a FM machine made in China, then changed to an imported machine; and Group B, who were treated using the reverse sequence. APD treatment was performed with 10 L/10 h and 5 cycles of exchange. After 72 h, the daily peritoneal Kt/V, the accuracy of the injection rate, accuracy of the injection temperature, safety, and manipulability of the machine were assessed. Noninferiority test was conducted between the two groups. Results: The daily peritoneal Kt/V in the APD machine made in China and the imported APD machine were 0.17 (0.14, 0.25) and 0.16 (0.13, 0.23), respectively. There was no significant difference between the groups (Z = 0.15, P = 0.703). The lower limit of the daily Kt/V difference between the two groups was 0.0069, which was greater than the noninferiority value of −0.07 in this study. The accuracy of the injection rate and injection temperature was 89.7% and 91.5%, respectively, in the domestic APD machine, which were both slightly better than the accuracy rates of 84.0% and 86.8% in the imported APD machine (89.7% vs. 84.0%, P = 0.2466; 91.5% vs. 86.8%, P = 0.0954). Therefore, the APD machine made in China was not inferior to the imported APD machine. The fuselage of the imported APD machine was space-saving, while the APD machine made in China was superior with respect to body mobility, man-machine dialog operation, alarm control, and patient information recognition. Conclusions: The FM machine made in China was not inferior to the imported APD machine. In addition, the FM machine made in China had better operability.

Abstract
OBJECTIVE To follow up the participants of the randomized clinical trial "Efficacy and Safety of Niaoduqing Particles () for Delaying Moderate-to-Severe Renal Dysfunction", and assess the long-term effects of Niaoduqing Particles on delaying the progression of renal dysfunction. METHODS Participants, who had previously been randomly assigned to receive Niaoduqing Particles or placebo for 24 weeks (146 cases in each group), were invited to follow-up and all were administered Niaoduqing Particles 5 g thrice daily and 10 g before bedtime for 24 weeks. The primary endpoints were changes in baseline serum creatinine (Scr) and estimated glomerular filtration rate (eGFR) after completion of the open-label treatment period. RESULTS After the double-blind period, the median (interquartile range) changes in Scr were 1.1 (-13.0-24.1) and 11.7 (-2.6-42.9) μmol/L for the Niaoduqing Particle and placebo groups, respectively (P=0.008), and the median changes in eGFRs were-0.2 (-4.3-2.7) and-2.21 (-5.7-0.8) mL•min-1•1.73 m-2, respectively (P=0.016). There were significant differences in the double-blind period changes in renal function between groups. After the open-label period, the median changes in Scr were 9.0 (-10.0-41.9) and 17.5 (-6.0-50.0) μmol/L for the Niaoduqing Particle and placebo groups according to baseline grouping, respectively (P=0.214), and the median changes in eGFRs were-2.3 (-6.4-1.9) and-3.7 (-7.5-1.1) mL•min-1•1.73 m-2, respectively (P=0.134). There were no statistical differences in the open-label period changes in renal function between groups. The eGFR reduction of participants who accepted Niaoduqing Particle treatment for 48 weeks was projected to 2.5 mL•min-1•1.73 m-2 per year. CONCLUSION Niaoduqing Particles appear to have long-term efficacy for patients with moderate-to-severe renal dysfunction. Although there was no statistical difference, the early use of Niaoduqing Paticles seems to ameliorate the worsening of renal function. (Trial registration No. ChiCTR-TRC-12002448).

Abstract
The present study was aimed to establish a modified method for culturing mouse renal proximal tubular epithelial cells (TECs). Renal cortex was isolated from mouse kidney and scissored into pieces. TECs were separated by digesting scissored renal cortex in type II collagenase combined with strainer filtration, and then cultured in DMEM. The morphology of TECs was observed under inverted microscopy. The cell proliferative ability was assessed by flow cytometry, and cell viability was analyzed by CCK-8 assay. The purity of TECs was identified by immunofluorescence. Immunofluorescence observation showed that more than 95% cells were epithelial marker CK18 positive and more than 90% cells expressed renal proximal TECs marker proteins, Villin, AQP1, and SGLT2. The cells could be subcultured for about 5 times. The cell proliferative ability declined following the repeated passage. This study introduced a modified efficient method for culturing highly purified mouse renal proximal TECs.

Abstract
Objective: To explore the relationship between meat consumption and metabolic syndrome (MS) in Chinese adults aged ≥18 years. Methods: The data were obtained from 2010- 2012 National Nutrition and Health Survey. A total of 34 923 subjects who completed the dietary survey, the physical examination and had the testing results of blood sugar and blood lipid levels were enrolled in this study. MS was defined according to the diagnostic criteria of China Diabetes Society 2013. The prevalence ratios of MS and each form of MS and related 95%CI were calculated after post stratification weight according to the population data (2009) released by the national bureau of statistics. Results: The average meat intake among subjects was 94.8 g/d. People who had meat consumption between 100 g/d and 199 g/d had the lowest prevalence of MS, abdominal obesity and hyperglycemia. As the meat consumption increased, the prevalence of MS in men increased. Men who had meat consumption of ≥300 g/d had a higher risk of MS than those who had low level of meat consumption, with prevalence ratio equaled to 1.46 (95%CI: 1.14~1.87). Similar trend was not observed in women. Conclusion: Moderate intake of meat is associated with reduced risk of MS in Chinese adults.

Abstract
Background: Chronic kidney disease (CKD) with moderate-to-severe renal dysfunction usually exhibits an irreversible course, and available treatments for delaying the progression to end-stage renal disease are limited. This study aimed to assess the efficacy and safety of the traditional Chinese medicine, Niaoduqing particles, for delaying renal dysfunction in patients with stage 3b-4 CKD. Methods: The present study was a prospective, randomized, double-blind, placebo-controlled, multicenter clinical trial. From May 2013 to December 2013, 300 CKD patients with an estimated glomerular filtration rate (eGFR) between 20 and 45 ml·min−1·1.73 m−2, aged 18–70 years were recruited from 22 hospitals in 11 Chinese provinces. Patients were randomized in a 1:1 ratio to either a test group, which was administered Niaoduqing particles 5 g thrice daily and 10 g before bedtime for 24 weeks, or a control group, which was administered a placebo using the same methods. The primary endpoints were changes in baseline serum creatinine (Scr) and eGFR after completion of treatment. The primary endpoints were analyzed using Student's t-test or Wilcoxon's rank-sum test. The present study reported results based on an intention-to-treat (ITT) analysis. Results: A total of 292 participants underwent the ITT analysis. At 24 weeks, the median (interquartile range) change in Scr was 1.1 (−13.0–24.1) and 11.7 (−2.6–42.9) μmol/L for the test and control groups, respectively (Z = 2.642, P = 0.008), and the median change in eGFR was −0.2 (−4.3–2.7) and −2.2 (−5.7–0.8) ml·min−1·1.73 m−2, respectively (Z = −2.408, P = 0.016). There were no significant differences in adverse events between the groups. Conclusions: Niaoduqing particles safely and effectively delayed CKD progression in patients with stage 3b-4 CKD. This traditional Chinese medicine may be a promising alternative medication for patients with moderate-to-severe renal dysfunction.

Abstract
One of the commonly accepted merits of cohort studies (CSs) refers to the exposure precedes outcome superior to other observational designs. We use Directed Acyclic Graphs to construct a causal graph among research populations under CSs. We notice that the substitution of research population in place of a susceptible one can be used for effect estimation. Its correctness depends on the outcome-free status of the substituted population and the performance of both screening and diagnosis regarding the outcomes under study at baseline. The temporal precedence of exposure over outcome occurs theoretically, despite the opposite happens in realities. Correct effect estimate is affected by both the suitability of population substitution and the validities of outcome identification and exclusion.

Abstract
BACKGROUND Urinary DcR2 (uDcR2) is a biomarker for the early detection the tubulointerstitial injury (TII) in patients with chronic kidney disease (CKD), but the high-dose hook effect may lead to falsely low or even negative results when using an enzyme-linked immunosorbent assay (ELISA). This study aimed to investigate if the high-dose hook effect exists with ELISA testing, and to uncover a potential approach for reducing this effect. METHODS 72 CKD patients were recruited and categorized into four groups based on TII scores. uDcR2 was measured in undiluted and serially diluted (two-, four-, eight- and 16-fold dilutions) urine using an ELISA kit. The results from the assay were normalized to urinary creatinine. We evaluated the correlation between uDcR2/cre levels at different dilutions and renal histological parameters. Receiver operating characteristic (ROC) curves were generated to examine the value of uDcR2/cre for predicting TII. RESULTS uDcR2/cre levels in the undiluted urine were significantly higher in patients with CKD than those in the control. However, higher TII scores did not yield higher levels of uDcR2/cre in the undiluted urine. After serial dilution, uDcR2/cre levels were highest with the four-fold dilution. A positive correlation was found between uDcR2/cre levels at different dilutions and TII scores, with the highest correlation coefficient and the largest AUC being observed at the four-fold dilution. CONCLUSIONS The high-dose hook effect was apparent during ELISA testing of uDcR2 in CKD patients, yet dilution of the urine samples neutralized this effect. However, the use of a four-fold dilution of urine for uDcR2/cre testing may eliminate the high-dose hook effect and make it possible to effectively monitor the severity of TII in CKD patients.

Abstract
Objective: To understand the prevalence of alcohol drinking in 20-79 years old males with different educational backgrounds and smoking behaviors in different areas of China. Methods: A multi-stage cluster random sampling survey was conducted in 150 surveillance sites in 2010-2012 Chinese nutrition and health surveillance in China. At least 1 000 subjects were selected in each surveillance site. Alcohol drinking prevalence and pattern information were collected by using personal health and food frequency questionnaire in face to face interviews. Results: A total of 60 791 males aged 20-79 years were surveyed. The prevalence of alcohol drinking was 57.8% (58.3% in rural area, 57.3% in urban area). The mean daily alcohol intake level was 32.7 g (33.3 g in rural area, 32.1 g in urban area). The rate of almost drinking every day and daily alcohol intake level were highest among males aged 50-59 years. Mean daily alcohol intake level, rate of almost drinking every day and excessive drinking decreased with the increase of education level. Non-smokers had higher rate of never drinking and lower prevalence of drinking and excessive drinking, lower mean daily alcohol intake level, and lower rate of almost drinking every day compared with current and past smokers. Conclusions: Alcohol drinking was common in males aged 20-79 years in China, and, the difference was not obvious between rural residents and urban residents. The differences in daily intake level of different alcohol drinks among males with different characteristics had certain significance. Significant difference in excessive drinking was found among different age groups, those with different education levels and those with different smoking history.

Abstract
Objective: To invesigate the epidemic status of the metabolic syndrome (MS) among mainland Chinese adolescents aged 10-17 in 2010-2012. Methods: Data were collected from Chinese Nutrition and Health Surveillance in 2010-2012. Multi-stage stratified proportion to the population cluster random sampling method was conducted to determine 16 872 adolescents in 150 counties from 31 provinces in mainland China. The epidemic status of metabolic syndrome was analyzed by China criterion (defined by Chinese Pediatric Society, Chinese Medical Association) and Cook criterion, respectively. The prevalence of MS and 95%CI were calculated through weighted complex sampling processing by population data released by the National Bureau of Statistics in 2009. Results: Based on China criterion, the weighted prevalence of MS was 2.4% (95% CI: 2.1%-2.6%) among Chinese adolescents aged 10-17. Prevalence in urban was higher than in rural (2.8%, 95%CI: 2.4%-3.2% and 1.9%, 95%CI:1.6%-2.3%, respectively). Prevalence in boys and girls were 2.7% (95% CI: 2.3%-3.0%), and 2.0% (95% CI: 1.7%-2.4%), respectively. Based on Cook criterion, the weighted prevalence was 4.3% (95% CI: 4.0%-4.7%) . The highest weighted prevalence of the components of the metabolic syndrome was low high-density lipoprotein cholesterol (26.8%, 95% CI: 26.0%-27.5%), followed by high fasting glucose (11.5%, 95% CI: 11.0%-12.0%), abdominal obesity (11.1%, 95%CI: 10.6%-11.7%) , hypertriglyceridemia (8.8%, 95%CI: 8.4%-9.3%) , and high blood pressure (6.4%, 95% CI: 6.0%-6.8%). Conclusion: Among the five indicators of metabolic syndrome, the prevalence of central obesity and hypertriglyceridemia were relative high in Chinese adolescents aged 10-17 years, though the prevalence of metabolic syndrome was not high.

Abstract
Background: Patients on hemodialysis have a high-mortality risk. This study analyzed factors associated with death in patients on maintenance hemodialysis (MHD). While some studies used baseline data of MHD patients, this study used the most recent data obtained from patients just prior to either a primary endpoint or the end of the study period to find the characteristics of patients preceding death. Methods: Participants were selected from 16 blood purification centers in China from January 2012 to December 2014. Patients’ data were collected retrospectively. Based on survival status, the participants were divided into two groups: survival group and the death group. Logistic regression analysis was performed to determine factors associated with all-cause mortality. Results: In total, 4104 patients (57.58% male, median age 59 years) were included. Compared with the survival group, the death group had more men and more patients with diabetic nephropathy (DN) and hypertensive nephropathy. The patients preceding death also had lower levels of diastolic blood pressure, hemoglobin, serum albumin, serum calcium, serum phosphate, Kt/V, and higher age. Multivariate analysis revealed that male sex (odd ratio [OR]: 1.437, 95% confidence interval [CI]: 1.094–1.886), age (OR: 1.046, 95% CI: 1.036–1.057), and presence of DN (OR: 1.837, 95% CI: 1.322–2.552) were the risk factors associated with mortality. High serum calcium (OR: 0.585, 95% CI: 0.346–0.989), hemoglobin (OR: 0.974, 95% CI: 0.967–0.981), albumin (OR: 0.939, 95% CI: 0.915–0.963) levels, and dialysis with noncuffed catheter (OR: 0.165, 95% CI: 0.070–0.386) were protective factors based on a multivariate analysis. Conclusions: Hemodialysis patients preceding death had lower hemoglobin, albumin, and serum calcium levels. Multivariate analysis showed that male sex, age, DN, low hemoglobin, low albumin, and low serum calcium were associated with death in hemodialysis patients.

Abstract
Tubulointerstitial injury (TII) plays a crucial role in the progression of diabetic nephropathy (DN), but lack of specific and sensitive biomarkers for monitoring TII in DN management. This study is to investigate whether urinary decoy receptor 2 (uDcR2) could serve as a novel noninvasive biomarker for assessing TII in DN. We recruited 311 type 2 diabetics and 139 DN patients who were diagnosed by renal biopsy. uDcR2 levels were measured by ELISA, and renal DcR2 expression was detected immunohistochemically. Associations between uDcR2 and renal DcR2 and renal functional parameters were evaluated. Receiver operating characteristics (ROC) curve analyzed area under the curve (AUC) of uDcR2 for assessing TII. Double staining was undertaken for renal DcR2 with proximal and distal tubular markers; senescent markers p16, p21, and senescence-associated β-galactosidase (SA-β-gal); and fibrotic markers collagen I and IV. We found DcR2 was primarily expressed in renal proximal tubules; uDcR2 levels were elevated per albuminuria stratum and correlated with renal functional parameters in diabetics and were associated with percentage of tubular DcR2 and TII score in DN. The uDcR2 had an AUC of 0.909 for assessing TII in DN by ROC analysis. Almost all tubular DcR2 was coexpressed with p16 and p21, and nearly more than one-half of tubular DcR2 was positive for SA-β-gal, primarily in collagen I- and IV-positive regions of DN. Our results indicate uDcR2 could potentially serve as a novel biomarker for TII and may reflect senescence of renal proximal tubular cells in DN pathogenesis.

Abstract
Clearance of amyloid-beta (Aβ) from the brain is an important therapeutic strategy for Alzheimer's disease (AD). Current studies mainly focus on the central approach of Aβ clearance by introducing therapeutic agents into the brain. In a previous study, we found that peripheral tissues and organs play important roles in clearing brain-derived Aβ, suggesting that the peripheral approach of removing Aβ from the blood may also be effective for AD therapy. Here, we investigated whether peritoneal dialysis, a clinically available therapeutic method for chronic kidney disease (CKD), reduces brain Aβ burden and attenuates AD-type pathologies and cognitive impairments. Thirty patients with newly diagnosed CKD were enrolled. The plasma Aβ concentrations of the patients were measured before and after peritoneal dialysis. APP/PS1 mice were subjected to peritoneal dialysis once a day for 1 month from 6 months of age (prevention study) or 9 months of age (treatment study). The Aβ in the interstitial fluid (ISF) was collected using microdialysis. Behavioural performance, long-term potentiation (LTP), Aβ burden and other AD-type pathologies were measured after 1 month of peritoneal dialysis. Peritoneal dialysis significantly reduced plasma Aβ levels in both CKD patients and APP/PS1 mice. Aβ levels in the brain ISF of APP/PS1 mice immediately decreased after reduction of Aβ in the blood during peritoneal dialysis. In both prevention and treatment studies, peritoneal dialysis substantially reduced Aβ deposition, attenuated other AD-type pathologies, including Tau hyperphosphorylation, glial activation, neuroinflammation, neuronal loss, and synaptic dysfunction, and rescued the behavioural deficits of APPswe/PS1 mice. Importantly, the Aβ phagocytosis function of microglia was enhanced in APP/PS1 mice after peritoneal dialysis. Our study suggests that peritoneal dialysis is a promising therapeutic method for AD, and Aβ clearance using a peripheral approach could be a desirable therapeutic strategy for AD.

Abstract
Cell senescence plays a major role in the progression of tumors and chronic conditions such as diabetes and chronic kidney disease. Senescent cells are an important model for the study of aging-related diseases, and there is currently no efficient method for sorting out senescent cells. Decoy receptor 2 (DcR2) is a transmembrane receptor of the tumor necrosis factor superfamily, which is specifically expressed in senescent cells. In this study, we used magnetic activated cell sorting (MACS) isolation of a highly-pure populations DcR2-positive renal tubular epithelial cells (RTECs) based on three senescent cell models including the fifth passage cells, advanced glycation end-products (AGEs)- and H2O2-induced cells. The percentages of DcR2 positive RTECs in G1 and S phases increased by 20% and 4%, respectively, as compared to that in the pre-sorted cells. The positivity rates of SA-β-gal, p16, and senescence-associated heterochromatin foci (SAHF) in DcR2-positive RTECs were about 40%, 30%, and 44% higher than that prior to cell sorting. The levels of IL-6 and TGF-β1 in the supernatant were increased by 1.7 and 1.5 folds, respectively, as compared to that observed prior to sorting. No significant cell death was observed after 5days of continuous culture. Ki-67 positive expression rate in DcR2 negative RTECs was significantly higher than that in DcR2 positive RTECs after MACS. We demonstrated the use of DcR2 to classify live, senescent RTECs with a high specificity and stability. Our findings lay the foundation for further study of senescent RTECs in the progression of chronic kidney disease.

Abstract
Objective: To investigate the spontaneous neoplastic lesions and their incidences in Sprague-Dawley (SD) and Wistar rats, and to accumulate background data for carcinogenicity studies. Methods: One hundred and eighty SD rats and 240 Wistar rats (4-week old) , half in each sex, were used in this study. The rats were housed routinely under specific pathogen-free environment and euthanized after 104 weeks. Histopathological examination was undertaken for all animals including deaths and scheduled euthanasia. The types and incidences of spontaneous tumors were gathered statistically. Results: Total 411 rats (176 SD rats and 235 Wistar rats) were examined in this study. The total tumor incidence of the 411 rats was 57.7%(237/411). The total tumor incidence in SD rats was 55.7%(98/176), benign tumor incidence was 48.9%(86/176) and malignant tumor incidence was 15.9%(28/176). The total tumor incidence in Wistar rats was 59.1%(139/235), benign tumor incidence was 51.5%(121/235) and malignant tumor incidence was 14.5%(34/235). The main benign tumors were pituitary adenoma (23.3% in SD rats, 12.3% in Wistar rats), breast fibroadenoma (21.3% in SD rats, 12.9% in Wistar rats) and breast adenoma (16.9% in SD rats, 9.5% in Wistar rats) in females; testis Leydig cell tumor (0 in SD rats, 14.3% in Wistar rats) in males. The main malignant tumors were breast carcinoma (10.1% in SD rats, 3.4% in Wistar rats) and uterine leiomyosarcoma (0 in SD rats, 2.6% in Wistar rats) in females; squamous cell carcinoma of skin (2.3% in SD rats, 0.9% in Wistar rats); subcutaneous fibrosarcoma (1.1% in SD rats, 2.1% in Wistar rats); brain malignant glioma (1.1% in SD rats, 1.7% in Wistar rats). Conclusions: In the study, a high incidence of spontaneous tumors is reported in both SD and Wistar rats housed for 2 years. The incidence of benign tumors is higher than that of malignant rumors. The benign tumors mainly are pituitary adenoma, breast fibroadenoma and breast adenoma in females, and testis Leydig cell tumor in males. The malignant tumors mainly are breast carcinoma and some soft tissue sarcomas. The results of the study enrich the data of spontaneous tumor in SD and Wisar rats and provide background data for carcinogenicity studies for new drugs.

Abstract
Nitrogen deficiency induces leaf senescence. However, whether or how nitrate might affect this process remains to be investigated. Here, we report an interesting finding that nitrate-instead of nitrogen-starvation induced early leaf senescence in nrt1.5 mutant, and present genetic and physiological data demonstrating that nitrate starvation-induced leaf senescence is suppressed by NRT1.5. NRT1.5 suppresses the senescence process dependent on its function from roots, but not the nitrate transport function. Further analyses using nrt1.5 single and nia1 nia2 nrt1.5-4 triple mutant showed a negative correlation between nitrate concentration and senescence rate in leaves. Moreover, when exposed to nitrate starvation, foliar potassium level decreased in nrt1.5, but adding potassium could essentially restore the early leaf senescence phenotype of nrt1.5 plants. Nitrate starvation also downregulated the expression of HAK5, RAP2.11, and ANN1 in nrt1.5 roots, and appeared to alter potassium level in xylem sap from nrt1.5. These data suggest that NRT1.5 likely perceives nitrate starvation-derived signals to prevent leaf senescence by facilitating foliar potassium accumulation.

Abstract
Copy number variations (CNVs) are important forms of structural variation in human and animals and can be considered as a major genetic component of phenotypic diversity. Here we used the Illumina PorcineSNP60 BeadChip V2 and a DLY [Duroc x (Large White x Landrace)] commercial hybrid population to identify 272 CNVs belonging to 165 CNV regions (CNVRs), of which 66 are new. As CNVRs are specific to origin of population, our DLY-specific data is an important complementary to the existing CNV map in the pig genome. Eight CNVRs were selected. for validation by quantitative real-time PCR (qRT-PCR) and the accurate rate was high (87.25%). Gene function analysis suggested that a common CNVR may play an important role in multiple traits, including growth rate and carcass quality.

Abstract
Premature senescence is an important event during diabetic nephropathy (DN) progression. Here, we investigated the role of endoplasmic reticulum (ER) stress-regulated activation of transcription factor 4 (ATF4)/p16 signaling in the premature senescence of renal tubular epithelial cells (RTECs) during DN development. In the renal tissues of Type 2 DN patients, we detected an increased number of senescent cells; elevated deposition of advanced glycation end products (AGEs); upregulated expression of ER stress marker, glucose-regulated protein 78; as well as overexpression of ATF4 and p16. Similarly, these phenomena were also observed in cultured mouse RTECs following AGE treatment. Interestingly, AGE-induced p16 expression and premature senescence were successfully attenuated by ER stress inhibitor and ATF4 gene silencing. Moreover, AGE-induced premature senescence was mimicked by ER stress inducers and ATF4 overexpression, while suppressed by p16 gene silencing. In addition, ER stress inducers can augment ATF4 expression. Therefore, our results demonstrate that the ER stress-regulated ATF4/p16 pathway is involved in the premature senescence of RTECs during DN progression.

Abstract
Primary breast lymphoma (PBL) is a rare disease accounting for 0.4-0.5 % of all breast malignancies. Accumulating evidence indicates that the diagnosis, prognostic factors, and optimal management of PBL are difficult. The present study aims to investigate the clinicopathological features and optimal treatment of PBL and to evaluate the institutional experience in this patient population. A total of 30 patients with PBL from January 2002 to December 2012 treated in He'nan Province Tumor Hospital were selected. The patients' clinical and pathological characteristics, treatment and response data, patterns of recurrence, and outcomes were retrospectively analyzed, and the relevant literatures were reviewed. All the cases were female, and the median age was 45. Diffuse large B cell lymphoma was the most common histological subtype seen in 23 of 30 patients. With a median follow-up time 32 months, median OS was 42 months (95 % CI 25-58 months), with 5-year OS rates 48 % (95 % CI 36-59 %). The median PFS was 14 months (95 % CI 6-30 months), with 5-year PFS rates 32 % (95 % CI 20-45 %). The prognostic factors that retained statistical significance for OS were IPI (P < 0.001), age (P = 0.04), and stage (P < 0.001). For PFS, significant prognostic factors were IPI (P = 0.01), radiotherapy given (P = 0.02) and stage (P = 0.02). PBL appears to have a worse prognosis. The present treatment method for PBL is a comprehensive way of diagnostic surgery together with radiotherapy and chemotherapy.

Abstract
BACKGROUND A multi-center large scale study is needed to confirm the efficacy and safety of domestic peritoneal dialysis (PD) solutions. Some researchers believe that 6 L/d is enough for adequate dialysis, but there is no multi-center prospective study on Chinese population to confirm this. In this study, we evaluated the efficacy and safety of domestic PD solution (Changfu) and its difference between 6 L and 8 L dosage. METHODS Adult PD patients who had taken PD therapy for at least one month were selected and divided into four groups according to two dialysis solution brands and two dialysis dosages, i.e., 6 L dose with Changfu dialysis solution, 6 L dose with Baxter dialysis solution, 8 L dose with Changfu dialysis solution, and 8 L dose with Baxter dialysis solution. After 48 weeks, the changes of primary and secondary efficacy indices were compared between different types and different dosages. We also analyzed the changes of safety indices. RESULTS Changes of Kt/V from baseline to 48 weeks between Changfu and Baxter showed no statistical differences; so did those of creatinine clearance rate (Ccr). Normalized protein catabolic rate (nPCR) from baseline to 48 weeks between Changfu and Baxter showed no statistical differences; so did those of net ultrafiltration volume (nUF) and estimated glomerular filtration rate (eGFR). Changes of nPCR from baseline to 48 weeks between 6 L and 8 L showed no statistical differences; so did those of nUF and eGFR. The decline of Kt/V from baseline to 48 weeks in 6 L group was more than that in 8 L group. Change of Ccr was similar. During the 48-week period, the mean Kt/V was above 1.7/w, and mean Ccr was above 50 L×1.73 m(-2)×w(-1). More adverse events were found in Changfu group before Changfu Corporation commenced technology optimization, and the statistical differences disappeared after that. CONCLUSIONS The domestic PD solution (Changfu) was proven to be as effective as Baxter dialysis solution. During 48-week period, a dosage of 6 L/d was enough for these patients to reach adequate PD. Clinical study promotes technological optimization, further helps to improve the safety indices of the medical products.

Abstract
The apoptotic or necrotic death of renal tubule epithelial cells is the main pathogenesis of renal ischemia-reperfusion-induced acute kidney injury (AKI). Pyroptosis is a programmed cell death pathway that depends on the activation of the caspase cascade and IL-1 cytokine family members. However, the role of pyroptosis in AKI induced by ischemia-reperfusion remains unclear. In this study, we found that the levels of the pyroptosis-related proteins, including caspase-1, caspase-11, and IL-1β, were significantly increased after 6 h of renal ischemia-reperfusion injury (IRI) and peaked at 12 h after IRI. Enhanced pyroptosis was accompanied by elevated renal structural and functional injury. Similarly, hypoxia-reoxygenation injury (HRI) also induced pyroptosis in renal tubule epithelial NRK-52E cells, which was characterized by increased pore formation and elevated lactate dehydrogenase release. In addition, obvious upregulation of the endoplasmic reticulum (ER) stress biomarkers glucose-regulated protein 78 and C/EBP homologous protein (CHOP) preceded the incidence of pyroptosis in cells treated with IRI or HRI. Pretreatment with a low dose of tunicamycin, an inducer of ER stress, relieved IRI-induced pyroptosis and renal tissue injury. Silencing of CHOP by small interfering RNA significantly decreased HRI-induced pyroptosis of NRK-52E cells, as evidenced by reduced caspase-11 activity and IL-1β generation. Therefore, we conclude that pyroptosis of renal tubule epithelial cells is a key event during IRI and that CHOP-caspase-11 triggered by overactivated ER stress may be an essential pathway involved in pyroptosis.

Abstract
Premature senescence is a key process in the progression of diabetic nephropathy (DN). In our study, we hypothesized that receptors for advanced glycation end-products (RAGE) mediate endoplasmic reticulum (ER) stress to induce premature senescence via p21 signaling activation in diabetic nephropathy. Here, we demonstrated that elevated expression of RAGE, ER stress marker glucose-regulated protein 78 (GRP78), and cell-cycle regulator p21 was all positively correlated with enhanced senescence-associated-β-galactosidase (SA-β-gal) activity in DN patients. In addition, the fraction of SA-β-gal or cells in the G0G1 phase were enhanced in cultured mouse proximal tubular epithelial cells (PTECs) and the expression of RAGE, GRP78 and p21 was up-regulated by advanced glycation end-products (AGEs) in a dose- and time-dependent manner. Interestingly, ER stress inducers or RAGE overexpression mimicked AGEs induced-premature senescence, and this was significantly suppressed by p21 gene silencing. However, RAGE blocking successfully attenuated AGEs-induced ER stress and p21 expression, as well as premature senescence. Moreover, ER stress inducers directly caused p21 activation, premature senescence, and also enhanced RAGE expression by positive feedback. These observations suggest that RAGE promotes premature senescence of PTECs by activation of ER stress-dependent p21 signaling.

Abstract
BACKGROUND Data on the epidemiology of hypertension in Chinese non-dialysis chronic kidney disease (CKD) patients are limited. The aim of the present study was to investigate the prevalence, awareness, treatment, and control of hypertension in the non-dialysis CKD patients through a nationwide, multicenter study in China. METHODS The survey was performed in 61 tertiary hospitals in 31 provinces, municipalities, and autonomous regions in China (except Hong Kong, Macao, and Taiwan). Trained physicians collected demographic and clinical data and measured blood pressure (BP) using a standardized protocol. Hypertension was defined as systolic BP ≥ 140 mmHg and/or diastolic BP ≥ 90 mmHg, and/or use of antihypertensive medications. BP < 140/90 mmHg and < 130/80 mmHg were used as the 2 thresholds of hypertension control. In multivariate logistic regression with adjustment for sex and age, we analyzed the association between CKD stages and uncontrolled hypertension in non-dialysis CKD patients. RESULTS The analysis included 8927 non-dialysis CKD patients. The prevalence, awareness, and treatment of hypertension in non-dialysis CKD patients were 67.3%, 85.8%, and 81.0%, respectively. Of hypertensive CKD patients, 33.1% and 14.1% had controlled BP to < 140/90 mmHg and < 130/80 mmHg, respectively. With successive CKD stages, the prevalence of hypertension in non-dialysis CKD patients increased, but the control of hypertension decreased (P < 0.001). When the threshold of BP < 130/80 mmHg was considered, the risk of uncontrolled hypertension in CKD 2, 3a, 3b, 4, and 5 stages increased 1.3, 1.4, 1.4, 2.5, and 4.0 times compared with CKD 1 stage, respectively (P < 0.05). Using the threshold of < 140/90 mmHg, the risk of uncontrolled hypertension increased in advanced stages (P < 0.05). CONCLUSIONS The prevalence of hypertension Chinese non-dialysis CKD patients was high, and the hypertension control was suboptimal. With successive CKD stages, the risk of uncontrolled hypertension increased.

Abstract
ZnO nanomaterials based surface acoustic wave (SAW) gas sensor has been investigated in ethanol environment at room temperature. The ZnO nanomaterials have been prepared through thermal evaporation of high-purity zinc powder. The as-prepared ZnO nanomaterials have been characterized with scanning electron microscopy (SEM), transmission electron microscopy (TEM) and X-ray Diffraction (XRD) techniques. The results indicate that the obtained ZnO nanomaterials, including many types of nanostructures such as nanobelts, nanorods, nanowires as well as nanosheets, are wurtzite with hexagonal structure and well-crystallized. The SAW sensor coated with the nanostructured ZnO materials has been tested in ethanol gas of various concentrations at room temperature. A network analyzer is used to monitor the change of the insertion loss of the SAW sensor when exposed to ethanol gas. The insertion loss of the SAW sensor varies significantly with the change of ethanol concentration. The experimental results manifest that the ZnO nanomaterials based SAW ethanol gas sensor exhibits excellent sensitivity and good short-term reproducibility at room temperature.

Abstract
Aim To investigate the osteogenic differentiation of vascular smooth muscle cells (VSMCs) in mice with chronic kidney disease (CKD) and to evaluate the effects of p53 on the osteogenic differentiation of the VSMCs. Methods Experimental models of CKD-associated vascular calcification generated by five-sixth (5/6) nephrectomy (Nx) and a high-phosphate (HP) diet were used in p53+/+ and p53–/– mice. Following 5/6 Nx, aortic calcification, markers of osteogenic differentiation, VSMCs and p53 protein in aortic tissues were studied. Results Aortic calcification was observed after eight weeks following 5/6 Nx in mice of both genotypes, and expression of the markers of osteogenic differentiation in the VSMCs was increased. These changes were continuously observed up to 12 weeks after 5/6 Nx, and particularly after 5/6 Nx + HP. Compared with p53+/+ mice, aortic calcification in p53–/– mice was more severe (p < 0.001). Expression of the markers of osteogenic differentiation was noticeably increased (p < 0.001), while expression of the marker of VSMCs had decreased (p < 0.001). Statistical analysis demonstrated that the markers of osteogenic differentiation were negatively correlated with p53, and the marker of VSMCs was positively correlated with p53 (p < 0.001). Conclusion p53 has the potential to negatively regulate the osteogenic differentiation of VSMCs in CKD mice.

Abstract
Interleukin-8 (IL-8) belongs to the superfamily of CXC chemokines, contributing to human cancer progression through potential mitogenic, angiogenic, and motogenic functions. We hypothesize that the functional polymorphism of IL-8 may influence the inflammatory process during pathological stage from hepatitis to hepatocellular carcinoma (HCC). Two polymorphisms in the IL-8 gene (-251A/T and +781C/T) were examined in 160 cases of chronic hepatitis B, 80 cases of hepatitis B virus (HBV)-related liver cirrhosis (LC), 150 cases of HBV-related HCC, and 150 healthy controls using polymerase chain reaction-restriction fragment length polymorphism method and DNA sequencing. In the LC group, the AA genotypes were associated with a significantly decreased risk of LC compared with the TT genotype (OR=0.14, 95% CI 0.02-0.87, p=0.035). The data also revealed that subjects with the A allele appeared to have lower susceptibility to LC than those with the T allele (OR=0.48, 95% CI 0.25-0.92, p=0.027). The +781C/T polymorphism of IL-8 was not found relevant to the liver diseases. This study indicated that the IL-8 gene -251 AA genotype might be a protect factor for LC.

Abstract
The information of complementary foods consumed by 14649 children aged from 4 to 24 months in poor rural areas was analyzed. On average, it was at 6 months old for children to start complementary feeding. Approximately one third of children started complementary feeding at 4-6 months old and 16.4% children were fed cereal foods before 4 months old. Only 50% of children aged 12 months and above consumed vegetables/fruits daily and 38% of them consumed animal foods. However, 15.8% children never ate animal foods, and 20% children were fed formula milk daily after weaning time. The impact of family dietary pattern on children's diet increased along with the growth of children. It is obvious that the irrational food pattern would undermine growth of children and such diet behavior would eventually result in malnutrition. Poor complementary feeding practice in some selected rural areas in China played a negative role on children's growth. Hence, nutrition education to the mothers and caretaker should be emphasized so that to improve their awareness of the importance of good nutrition practice and guide them to feed weaning children reasonably.

Abstract
Beta-Momorcharin (Mr approximately 29 kDa) is a single-chained ribosome-inactivating protein (RIP) with a branched hexasaccharide bound to Asn51. The crystal structure of beta-momorcharin has been determined using the molecular-replacement method and refined to 2. 55 A resolution. The final structural model gave an R factor of 17. 2% and root-mean-square deviations of 0.016 A and 1.76 degrees from ideal bond lengths and bond angles, respectively. beta-Momorcharin contains nine alpha-helices, two 310 helices and three beta-sheets, and its overall structure is similar to those of other single-chained RIPs. Residues Tyr70, Tyr109, Glu158 and Arg161 are expected to define the active site of beta-momorcharin as an rRNA N-glycosidase. The oligosaccharide is linked to the protein through an N-glycosidic bond, beta-GlcNAc-(1-N)-Asn51, and stretches from the surface of the N-terminal domain far from the active site, which suggests that it should not play a role in enzymatic function. The oligosaccharide of each beta-momorcharin molecule interacts with the protein through hydrogen bonds, although in the crystals most of these are intermolecular interactions with the protein atoms in an adjacent unit cell. This is the first example of an RIP structure which provides information about the three-dimensional structure and binding site of the oligosaccharide in the active chains of RIPs.

Abstract
The three-dimensional structure of a new crystal form of methanol dehydrogenase from Methylophilus W3A1 has been obtained in the presence of substrate using data recorded at a synchrotron. The structure of this approximately 140 kDa heterotetramer, refined at 1. 9 A resolution, reveals the detailed configuration of its redox cofactor, pyrroloquinoline quinone (PQQ). C4, one of the oxygen-bearing atoms of this orthoquinone is in a planar configuration while C5, which bears the other quinone oxygen, is tetrahedral, suggesting that the PQQ is in the semiquinone redox state. The substrate binding site has been identified close to PQQ and to the side chain of Asp297, the putative active site base. The proximity of the hydroxyl of methanol to C5 of PQQ compared to the greater separation of the substrate methyl group from C5 supports the addition-elimination reaction mechanism involving a hemiketal intermediate.
