ABSTRACT
Objective Observed the characteristics and influence factors of blood pressure circadian rhythm in continuous ambulatory peritoneal dialysis patients.To investigate the effect of residual renal function and cardiac function.Methods Prospectively collected 120 cases of continuous ambulatory peritoneal dialysis from June 2016 to March 2017 in Tangshan renal medicine dialysis centers,who combined with hypertension were treated with peritoneal dialysis for more than 3 months.According to the dynamic monitoring blood pressure circadian rhythm of blood pressure,120 cases were divided into the normal rhythm of blood pressure and the abnormal blood pressure rhythm group.Collected medical history;Tested related test index respectively;Cardiac ultrasound.According to the formula to calculate residual renal function,left ventricular mass index,Eingabe/Ausgabe,Ejection Fraction.Univariate and multivariate unconditional logistic regression analysis was used to analyze the risk factors of circadian rhythm of blood pressure.Stepwise multiple linear regression analysis was used to analyze the risk factors of residual renal function and cardiac function.Results CAPD patients with normal blood pressure rhythm in 14 cases(11.7％),abnormal blood pressure rhythm in 106 cases(88.3％),Among them,non dipper blood pressure accounted for 75 cases(62.5％).Single factor and multiple factors unconditioned logistic regression analysis revealed that after the comparison of gender and age,Risk factors for abnormal circadian rhythm of blood pressure were:UA(OR=1.197,95％CI:1.099-1.441),CRP(OR=1.170,95％CI:1.061-1.331),RRF(OR=1.389,95％CI:1.160-1.779).Using stepwise multiple linear regression analysis of dangerous factors affecting residual renal function and cardiac function,we found:Residual renal function negatively correlated with left ventricular myocardial mass index,systolic blood pressure drops at night rate,and ultrafiltration volume;LVMI (cardiac function) Positively correlated with 24 h average systolic blood pressure,and negatively correlated with systolic blood pressure drop ratio and residual renal function at night.Abnormal circadian rhythm of blood pressure may lead to the decline of residual renal function and cardiac function.Conclusions UA,CRP and RRF may affect the CAPD patients blood pressure circadian rhythm.At the same time,abnormal circadian rhythm of blood pressure may lead to the decline of residual renal function and cardiac function.Therefore,pay attention to the monitoring and control of ABPM,can better protect the residual renal function and improve cardiac function,so as to prolong and improve the survival time and quality of life of patients with CAPD.
ABSTRACT
Objective To establish a prediction model for 3-years recurrence after initial ischemic stroke by Cox proportional hazards regression and individual prognostic Index(PI)equation, and to evaluate its application value and external reality. Methods The inpatients with cerebral ischemic stroke hospitalized in Neurology Department in North China University of Science and Technology Affiliated Hospital were finally internalized between January 2013 and December 2013.Follow-up study on recurrence was carried out between January 2016 and December 2016.The recurrence prediction model was constructed by the Cox proportional hazards regression model.During January 2016 and December 2016,data of patients with ischemic stroke were prospectively continuously collected.And PI equation was used to verify its external reality in ischemic stroke patients. Results A total of 184 cases had stroke recurrence during the follow-up period.The Cox proportional hazards regression model analysis showed that age(RR=1.303,95% CI:1.019-1.666),history of heart disease(RR=1.788,95% CI:1.127-2.836),hypertension(RR=1.897,95% CI:1.097-3.280),diabetes(RR= 1.674,95% CI:1.015-2.760)and total cholesterol(RR= 2.136,95% CI:1.396-3.266)were the independent risk factors for stroke recurrence.The established recurrence model was correlated with individual PI equation,which was PI = 0.265X1+ 0.581X2+ 0.640X3+ 0.515X4+0.759X5.By the validation study of PI equation to predict stroke recurrence among patients admitted later, the sensitivity was 0.719,specificity was 0.769,and accuracy was 0.800. Conclusions Age,history of heart disease,hypertension,diabetes,and total cholesterol are independent risk factors for recurrence of ischemic stroke.And the PI for predicting stroke recurrence within 3 years after initial stroke is successfully established,which is good and helpful for predicting ischemic stroke recurrence.

ABSTRACT
Objective To investigate the relationship between low-grade albuminuria and unfavourable cardiac geometric adaptations and left ventricular diastolic dysfunction in non-treated essential hypertensive(EH ) patients. Methods Three hundred and one patients of EH were divided into three groups acording to morning urine albumin concentration ( MU AC ): normoalbuminuria (NAU) group ( 107 cases,MUAC ＜ 10 mg/L) ;low-gradealbuminuria (LGAU) group ( 127 cases, MUAC 10-30 mg/L); microalbuminuria (MAU) group (67 cases, MUAC ＞ 30 mg/L). The blood pressure,body height and weight was measured for all the patients. The serum creatinine (SCr),blood urea nitrogen (BUN), uric acid (UA),fasting plasma glucose (FBG), plasma glucose 2 hours after oral glucose load (2hPG), total cholesterol (TC), triglyceride (TG) and low density lipoprotein cholesterol (LDL-C) were detected by automatic biochemical analyzer.Echocardiogram exarmination was performed to detect left ventricular end-diastolic diameter (LVEDD), left ventricular end-diastolic posterior wall thickness (LVPWT) and interventricular septum thickness at end-diastole (IVST). Color Doppler ultrasound was used to measure indicators of left ventricular diastolic function, including peak E velocity of mitral diastolic flow (E) and peak A velocity of mitral diastolic flow ( A ), calculated E/A, measured the deceleration time of peak E ( DT ), and isovolumic relaxation time (IV RT ).Left ventricular mass index (LVMI) and relative wall thickness(RWT) were calculated by formula, and LVMI,RWT,left ventricular configuration diastolic dysfunction was compared. Results The level of MUAC had positive relationship with LVMI (r = 0.43 ,P ＜ 0.01 ). Compared with that in NAU group, IVST, LVPWT,RWT, LVMI increased (P ＜ 0.01 ), the ratio of left ventricular normal configuration decreased (P ＜ 0.01 ), the incidence of concentric reconstitution, concentric hypertrophy increased (P ＜ 0.05 ), A increased (P ＜ 0.05 ),and E/A decreased (P ＜ 0.01 ) in LGAU group. The total incidence of left ventricular diastolic dysfunction was 28.6%(86/301 ),12.1%(13/107),33.9%(43/127) and 44.8%(30/67)in NAU group,LGAU group and MAU group. The incidencerates of left ventricular diastolic dysfunction in LGAU group and MAU group were higher than that in NAU group (P ＜ 0.01 ). Conclusion LGAU is positively related to incidence of unfavourable cardiac geometric adaptations and left ventricular diastolic dysfunction in EH patients.
