RESUMO
Objective@#To investigate the sex- and age-specific association between resting heart rate and hypertension in rural adult residents of Henan province.@*Methods@#At baseline, a total of 20 194 participants were randomly selected from Xin′an County of Henan province between July 2007 and August 2008. After excluding participants with hypertension or without resting heart rate data at baseline, and participants died or without hypertension outcome or diagnosed as gestational hypertension during follow-up between July 2013 and October 2014, 10 212 participants were finally included in this study. Multiple linear regression model was used to examine the association between resting heart rate and change of blood pressure. Logistic regression model was used to estimate the association between resting heart rate and risk of hypertension.@*Results@#There were 2 059 new hypertensive cases (839 male) during the 6 years follow-up. After controlling for potential confounders, per 5 beats/minutes increases in resting heart rate was associated with 0.18 mmHg (1 mmHg=0.133 kPa) (95%CI 0.01-0.36 mmHg, P=0.046) absolute increase in systolic blood pressure and 7% higher risk of developing hypertension in women (95%CI 1.03-1.11, P<0.05). Compared with resting heart rate<70 beats/minutes, the adjusted RRs for 76-82 and>82 beats/minutes groups were 1.39 (95%CI 1.18-1.63, P<0.05) and 1.22 (95%CI 1.02-1.45, P<0.05), respectively. For both age groups, increased resting heart rate was positively associated with risk of hypertension in women(RR=1.05(95% CI 1.01-1.10), P<0.05 (the women those <60 years); RR=1.14(95% CI 1.04-1.25), P<0.05 (the women those≥60 years). However, no significant association was found between resting heart rate and hypertension in male residents.@*Conclusions@#Increased resting heart rate is associated with high risk of hypertension in women who live in rural area, especially in elder women of this cohort.
RESUMO
Objective To identify the independent risk factors of esophageal varices ( EV) in cirrhosis by endoscopic ultrasonography ( EUS) , and further to establish a risk assessment model for predicting EV occurrence and evaluate the clinical predictive value of the model. Methods A retrospective cohort study was used in this study. Data of patients with cirrhosis without varicosity, who were hospitalized in Tianjin Second People's Hospital from September 2014 to March 2017 were collected. The location, diameter, and number of esophageal collateral circulation were measured by EUS. The non-selective beta blocker ( NSBB) medication history and antiviral therapy were recorded. The time of the first EUS examination was taken as the starting point and the follow-up period was set up as 18 months. The end point was the occurrence of EV or the end of follow-up. The independent risk factors of EV occurrence were determined by univariate and multivariate logistic regression analysis, and the risk assessment model of EV occurrence was constructed. The predictive value of evaluation model for disease was studied by ROC analysis. Hosmer-Lemeshow goodness of fit was used to test the fitting efficiency of the evaluation model. Results A total of 638 subjects were recruited initially, 13 of them were lost in the course of the study. Finally, 625 cases were included in the study. Among them, 369 cases did not develop EV ( the non-progress group) and 256 cases developed EV (the progress group). (1) Multivariate logistic regression analysis showed that 7 independent risk factors were selected into the risk assessment model of EV occurrence, and were assigned corresponding scores:no NSBB (3 points), no antiviral treatment (2 points), Child-Pugh stage B (1 point), the diameter of peri-ECV>2 mm ( 1 point) , the number of peri-ECV≥5 ( 3 points) , the diameter of para-ECV≥5 mm ( 4 points) , and the number of para-ECV≥5 ( 4 points) . ( 2) In the risk assessment model, the risk factor scores ranged from 1 to 4 with a total score of 0-18. The predicted incidence of EV increased from 0. 003 to 1. 000 with the increase of the score. ( 3) In the risk assessment model, the total risk score≤2 was assigned into low-risk group, 3-5 into medium-risk group, and ≥6 into high-risk group. The actual EV incidence of each risk stratification was 2. 78% in the low-risk group, 36. 36% in the medium-risk group and 93. 91% in the high-risk group, respectively. (4) The ROC analysis showed that area under curve (AUC) was 0. 947 (P<0. 05), suggesting that the risk assessment model had a good effect on predicting disease progression. Hosmer-Lemeshow test showed that P was 0. 450, suggesting that the model fitted well. Conclusion The risk assessment model based on EUS can accurately predict the occurrence of EV, and is simple and easy to use. The model can provide scientific basis for the prevention and rational treatment of EV in liver cirrhosis.

RESUMO
Objective To assess the clinical value of endoscopic ultrasonography ( EUS ) for predicting esophageal varices ( EV ) progression in patients with hepatitis B virus ( HBV )-related hepatocirrhosis. Methods A retrospective cohort study was performed on 299 HBV-related hepatocirrhosis patients with light EV in Tianjin Second People′s Hospital admitted from September 2014 to September 2015. The diameter and number of peri-esophageal collateral veins ( ECV ) and para-ECV were measured and described by EUS. The first EUS examination time was the starting point, and the follow-up of 24 months or EV progression was the end. Risk factors of EV progression were evaluated by multivariate Cox regression model, and the predictive value of EUS for EV progression was analyzed by receiver operating characteristic ( ROC) curve. Results The cumulative incidence of EV progression was 2. 3% ( 7/299 ) , 14. 8%( 44/297) , 33. 7% ( 96/285) and 40. 0% ( 120/273) at 6 months, 12 months, 18 months and 24 months of follow-up, respectively. The results of multivariate Cox regression analysis showed that the diameter of peri-ECV ( P=0. 0112, HR=1. 3232, 95%CI: 1. 0656-1. 6429 ) , the number of peri-ECV ( P=0. 0001, HR=1. 3666, 95%CI:1. 1634-1. 6052) and para-ECV diameter ( P=0. 0002, HR=1. 3641, 95%CI:1. 1558-1. 6100) were risk factors for EV progression. The use of nucleoside analogues treating HBV (P=0. 0020, HR=0. 4969, 95%CI: 0. 3186-0. 7751) and non-selective β-blockers descending portal venous pressure ( P=0. 0765, HR=0. 5732, 95%CI:0. 3097-1. 0611) were the protective factors for EV progression. The results of ROC curve analysis showed that the diameter of peri-ECV[ P<0. 001, area under the curve (AUC)= 0. 850, 95%CI: 0. 804-0. 895], the number of peri-ECV (P<0. 001, AUC=0. 831, 95%CI: 0. 784-0. 878), the diameter of para-ECV (P<0. 001, AUC=0. 924, 95%CI: 0. 895-0. 954) , and the number of para-ECV ( P<0. 001, AUC=0. 761, 95%CI: 0. 704-0. 817 ) had higher predictive value for EV progression;and the optimum cut-off values of each index were 1. 85 mm, 3. 5, 3. 35 mm, and 4. 5, respectively. The accuracies of prediction for EV progression were 76. 60%, 75. 19%, 84. 48% and 70. 29%, respectively. Conclusion EUS can be used to predict EV progression in HBV-related hepatocirrhosis patients. Peri-ECV diameter>1. 85 mm, number>3. 5, and para-ECV diameter>3. 35 mm, number>4. 5 suggest a high risk of EV progression. For patients with HBV-related hepatocirrhosis complicated with mild EV, nucleoside analogues to anti-HBV and non-selective β-blockers to reduce portal hypertension can prevent EV progression.
RESUMO
Objective: To study the modification effect of age on the association between body mass index and the risk of hypertension. Methods: People age ≥18 years old were selected by clusters, from a rural area of Henan province. In total, 20 194 people were recruited at baseline during 2007 and 2008, and the follow-up study was completed from 2013 to 2014. Logistic regression model was used to assess the risk of incident hypertension by baseline BMI and age-specific BMI. Results: During the 6-year follow-up period, 1 950 hypertensive persons were detected, including 784 men and 1 166 women, with cumulative incidence rates as 19.96%, 20.51%, and 19.61%, respectively. Compared with those whose BMI<22 kg/m(2), the RRs of hypertension were 1.09 (0.93-1.27), 1.17 (1.01-1.37), 1.34 (1.14-1.58) and 1.31 (1.09-1.56) for participants with BMI as 22-, 24-, 26- and ≥28 kg/m(2), respectively. In young and middle-aged populations, the risk of hypertension gradually increased with the rise of BMI (trend P<0.05). However, in the elderly, the increasing trend on the risk of hypertension risk was not as significantly obvious (trend P>0.05). Conclusion: The effect of BMI on the incidence of hypertension seemed to depend on age. Our findings suggested that a weight reduction program would be more effective on young or middle-aged populations, to prevent the development of hypertension.

Objective: To investigate the relationship between body mass index (BMI) and all-cause mortality in hypertensive population. Methods: All participants were selected from a prospective cohort study based on a rural population from Henan province, China. Cox proportional hazards regression models were used to estimate the associations of different levels of BMI stratification with all-cause mortality. Restricted cubic spline models were used to detect the dose-response relation. Results: Among the 5 461 hypertensive patients, a total of 31 048.38 person-years follow-up was conducted. The median of follow-up time was 6 years, and 589 deaths occurred during the follow-up period. Compared to normal weight group (18.5 kg/m(2)<BMI<24.0 kg/m(2)) the multivariate-adjusted hazard ratios for all-cause mortality associated with BMI levels (<18.5 kg/m(2), 24-28 kg/m(2), and ≥28 kg/m(2)) were 0.83 (95%CI: 0.37-1.87), 0.81 (95%CI: 0.67-0.97), and 0.72 (95%CI: 0.56-0.91), respectively. The dose-response analysis showed a nonlinear, reverse "S" shaped relationship (non-linearity P<0.001). Conclusion: Overweight or obese might have a protective effect on all-cause mortality in hypertensive population, which supports the "obesity paradox" phenomenon.

Objective@#To explore the effects of cardiac support on delayed resuscitation in extensively burned patients with shock.@*Methods@#Clinical data of 62 extensively burned patients with shock on admission, admitted to the 159th Hospital of PLA (hereinafter referred to as our hospital) from January 2012 to January 2017, were retrospectively analyzed. They were divided into cardiac support group (n=35) and control group (n=27) according to the use of deslanoside and ulinastatin. All patients were treated with routine fluid resuscitation based on the formula of the Third Military Medical University till post injury hour (PIH) 48. Patients in cardiac support group were given slow intravenous injection of deslanoside which was added in 20 mL 100 g/L glucose injection with first dose of 0.4 to 0.6 mg, 0.2 to 0.4 mg per 6 to 8 h, no more than 1.6 mg daily, and slow intravenous injection of 1×105U ulinastatin which was added in 100 mL 50 g/L glucose injection, once per 12 h. Other treatments of patients in the two groups followed the same conventional procedures of our hospital. The following data of the two groups of patients were collected. (1) The data of urine volume per hour within PIH 48, heart rate, mean arterial pressure (MAP), central venous pressure (CVP), blood lactic acid, base excess, hematocrit, and albumin at PIH 48 were recorded. (2) The input volumes of electrolyte, colloid within the first and second 24 hours post burn and the total fluid input volumes within PIH 48 were recorded. (3) The data of creatine kinase, creatine kinase isoenzyme-MB, lactate dehydrogenase, total bile acid, alanine aminotransferase, aspartate aminotransferase, β2-microglobulin, urea nitrogen, and creatinine at PIH 48 were recorded. (4) The complications including cardiac failure, pulmonary edema, pleural effusion, seroperitoneum, renal failure, sepsis, and death were also recorded. Data were processed with independent sample ttest, Fisher′s exact test, Pearson chi-square test, or continuous correction chi-square test.@*Results@#(1) There were no statistically significant differences in urine volume within PIH 48, heart rate, MAP, CVP, hematocrit, or albumin at PIH 48 between the patients of two groups (t=0.150, 0.488, 0.805, 0.562, 1.742, 0.696, P>0.05). While the levels of blood lactic acid and base excess were respectively (4.2±2.2) and (-4.3±2.0) mmol/L in patients of cardiac support group, which were significantly better than (5.9±1.7) and (-6.0±3.1) mmol/L in patients of control group (t=3.249, 2.480, P<0.05 or P<0.01). (2) There was no statistically significant difference in input volume of colloid within the first 24 hours post burn between the patients of two groups (t=0.642, P>0.05). The input volume of electrolyte within the first 24 hours post burn, the input volumes of electrolyte and colloid within the second 24 hours post burn, and the total fluid input volume within PIH 48 of patients in cardiac support group were significantly less than those in control group (t=2.703, 4.223, 3.437, 2.515, P<0.05 or P<0.01). (3) The levels of creatine kinase, creatine kinase isoenzyme-MB, lactate dehydrogenase, total bile acid, alanine aminotransferase, aspartate aminotransferase, β2-microglobulin, urea nitrogen, and creatinine of patients in cardiac support group at PIH 48 were significantly lower than those in control group (t=3.066, 3.963, 3.225, 2.943, 2.431, 3.084, 4.052, 2.915, 3.353, P<0.05 or P<0.01). (4) The occurrences of pleural effusion and seroperitoneum and mortality of patients in cardiac support group were significantly lower than those in control group (χ2=5.514, 6.984, 4.798, P<0.05 or P<0.01). There were no statistically significant differences in cardiac failure, pulmonary edema, renal failure, and sepsis between the patients of two groups [χ2=1.314 (sepsis), P>0.05].@*Conclusions@#The cardiotonic and cardiac protection treatments in delayed resuscitation of extensively burned patients with shock contribute to improving the cellular anonic metabolism, reducing the volume of fluid resuscitation, and mitigating the ischemic and hypoxic damage to organs, so as to lay foundation for decreasing further complication incidences and mortality.
RESUMO
Objective@#To investigate the relationship between physical activity (PA) and the risk of incident hypertension among population in rural areas of China.@*Methods@#The Community Intervention of Metabolic Syndrome in China & Chinese Family Health Study (CIMIC) was conducted in 2007-2008. Data on PA, smoking, drinking, blood pressure and other variables were obtained at baseline. Then the follow-up study of incident hypertension was performed during 2012-2015. A total of 41 457 participants aged ≥18 years and free from hypertension at baseline were included in the final analyses. PA was calculated as metabolic equivalent (MET) for each participant. Cox proportional hazard models were used to explore the relationship of PA with incident hypertension according to the quartiles of PA.@*Results@#A total of 6 780 participants developed hypertension during an average follow up of 5.8 years. The annual incidence of hypertension was 2.80%. Compared to participants in the first quartile of PA, HR (95%CI) of incident hypertension decreased with the level of PA of 0.92 (0.86, 0.99), 0.72 (0.67, 0.77) and 0.70 (0.65, 0.75) for the 2nd, 3rd and 4th quartile, respectively (Ptrend<0.001). In subgroup analyses, compared to the first quartile, hazards of hypertension among normotensive participants (systolic blood pressure less than 120 mmHg (1 mmHg=0.133 kPa) and diastolic blood pressure less than 80 mm Hg) in the 2nd, 3rd and 4th quartile were 0.82 (0.70, 0.95), 0.73 (0.63, 0.85) and 0.78 (0.67, 0.90), respectively (Ptrend=0.002). Among participants with prehypertension (systolic blood pressure from 120 to 139 mmHg and/or diastolic blood pressure from 80 to 89 mmHg), similar trend for the relationship of PA and incident hypertension was also found with HR (95%CI) of 0.94 (0.87, 1.01), 0.71 (0.65, 0.77) and 0.66 (0.61, 0.71) for the 2nd, 3rd and 4th quartile, respectively (Ptrend<0.001).@*Conclusion@#There was linear trend association between PA and incident hypertension. Increased PA in daily life may be a protective factor against hypertension.

RESUMO
Objective To assess the predictive value of endoscopic ultrasonography(EUS)for esophageal varices(EV)bleeding by studying the relationship between esophageal collateral veins(ECV), portal vein(PV)trunk with its main branches and EV bleeding. Methods A retrospective cohort study of 114 cases of moderate and severe EV was conducted. The ECV level was determined through EUS. At the same time,diameters of PV,azygos vein(AIV)and spleen vein(SV)were measured through EUS. The predictive value of ECV level and diameters of PV, AIV, SV for EV bleeding were assessed during the 1-year follow-up, which started from the first EUS examination to EV bleeding or the end of follow-up. Results Single factor Cox regression analysis showed severe peri-ECV varices had higher risk than mild in EV bleeding(HR=4.081,95%CI:1.833-9.086,P=0.001); severe para-ECV varices had higher risk than mild in EV bleeding(HR= 4.042, 95%CI:1.814-9.005,P= 0.001). Multivariable Cox retrospective analysis showed ECV level was an effective predictor for EV bleeding, when the peri-ECV and para-ECV were severe varices, EV bleeding risk increased to 3.831 3(P=0.004 3)and 3.493 3(P=0.003 1) times compared with mild respectively. Diameters of PV,AIV and SV could predict EV bleeding(PV AUC=0.959,P<0.001;AIV AUC=0.958,P<0.001;SV AUC=0.830,P<0.001).In addition, when diameter of PV>13.65 mm(sensitivity=0.94, specificity=0.84), AIV>8.65 mm(sensitivity=0.94, specificity=0.89),SV>9.45 mm(sensitivity=0.90, specificity=0.67), EV bleeding risk increased significantly. Conclusion EUS is helpful to predict the risk of moderate and severe EV bleeding, and severe varices of ECV,PV,AIV,and SV can be used as indicators to predict risk of EV bleeding.

RESUMO
Objective To assess the relationship between the recurrence of esophageal varices fol?lowing endoscopic esophageal varix ligation (EVL) and esophageal collateral veins(ECV)under endoscopic ultrasound ( EUS) , and analyze the predictive value of EUS for recurrence of esophageal varices. Methods Sixty patients with cirrhotic portal hypertension combined with esophageal varices underwent EVL for eradica?tion of varices. Endoscopy and EUS were performed before ligation to detect and describe the type of esopha?geal varices, and grade, location, and the number of ECV. Over a 12?month period, variceal recurrence was examined. The statistical analyses were performed to assess the relationship between esophageal varices fol?lowing EVL and ECV. Results Of the 60 patients, 29 ( 48?3%) had variceal recurrence within 12 months after EVL. Univariate logistic regression analysis showed that severe peri?ECV ( OR=22?67;95%CI:4?37? 117?47, P<0?001) ,severe para?ECV( OR=16?31;95%CI:0?84?108?14, P=0?018) , multiple peri?ECV ( OR=22?67;95%CI:4?37?117?47, P<0?001) , and the presence of perforating veins ( OR=6?67,95%CI:1?46?30?43,P=0?014) were significantly related to the variceal recurrence after EVL. Multivariate logis?tic regression model showed that severe peri?ECV ( OR=24?39;95%CI:2?34?253?78,P=0?008) and mul?tiple peri?ECV (OR=24?39;95%CI: 2?34?253?78,P=0?008) severe para?ECV(OR=19?42; 95%CI:4?84?148?54,P=0?012) remained independent prognostic factors for variceal recurrence. The sensitivity and specificity of multivariate logistic regression model in predicting variceal recurrence were 89?2% and 90?5%, respectively (prognostic value AUC=0?946).The sensitivity and specificity were 86?4% and 87?7% in pre?dicting variceal recurrence( prognostic value AUC=0?871) . Conclusion Recurrence rate of esophageal var?ices after EVL is high. EUS can clearly depict ECV. Severe peri?ECV and multiple peri?ECV are significant and independent prognostic factors associated with variceal recurrence risk. EUS before EVL will help predict variceal recurrence after EVL.

RESUMO
UNLABELLED: The ingredient declaration on food labels assumes paramount importance in the protection of food-allergic consumers. China has not implemented Food allergen labeling. A gold immunochromatography assay (GICA) was developed using 2 monoclonal antibodies (mAb) against the milk allergen ß-lactoglobulin in this study. The GICA was specific for pure milk samples with a sensitivity of 0.2 ng/mL. Milk protein traces extracted from 110 food products were detected by this method. The labels of 106 were confirmed by our GICA method: 57 food samples originally labeled as containing milk were positive for ß-lactoglobulin and 49 food samples labeled as not containing milk were negative for ß-lactoglobulin. However, 3 food samples falsely labeled as containing milk were found to contain no ß-lactoglobulin whereas 1 food sample labeled as not containing milk actually contained ß-lactoglobulin. First, these negatives could be because of the addition of a casein fraction. Second, some countries demand that food manufacturers label all ingredients derived from milk as "containing milk" even though the ingredients contain no detectable milk protein by any method. Our GICA method could thus provide a fast and simple method for semiquantitatation of ß-lactoglobulin in foods. PRACTICAL APPLICATION: The present method provides a fast, simple, semiquantitative method for the determination of milk allergens in foods.

Objective To evaluate 10-year risk of ischemic cardiovascular diseases (ICVD) in middle-aged adults in Henan province to provide evidence for improved health status. Methods The 10- year risk of ICVD in 12 064 middle-aged adults was evaluated by using simplified risk estimation model. Results About 96. 35% of male and 98. 29% of female had a probability of < 10% to develop ICVD over 10 years; 3.65% of male and 1.71% of female had a probability of ≥ 10% to develop ICVD over 10 years; and 0.68% of male and 0.23% of female had a probability of≥20% to develop ICVD over 10 years. The prevalence of risk factors for ICVD in two absolute risk groups ( ≥10% vs < 10% ) was significantly different. Conclusions The risk of ICVD in the middle-aged residents of Henan province may be similar to that in the middle-aged Chinese adults. The risk assessment for ICVD could be used for high- risk populations.
