Objective: To investigate the correlation between frailty status and anticoagulation therapy in elderly patients with atrial fibrillation. Methods: A total of 131 atrial fibrillation inpatients in our hospital aged 70 years and over with a mean age of(77.4±6.4)years were enrolled from January 2017 to June 2018 in this retrospective study.According to the state of anticoagulation therapy at discharge, patients were divided into the anticoagulation group(n=67)and the non-anticoagulation group(n=64). Data including gender, age, N-terminal pro-brain natriuretic peptide(NT-proBNP), glomerular filtration rate(eGFR), the type of medication, HAS-BLED(Hypertension, abnormal renal/liver function, stroke, bleeding history or predisposition, labile international normalized ratio, elderly, drugs/alcohol concomitantly), CHA2DS2-VASc scores, Charlson comorbidity index and clinical frailty scores(CFS)were recorded and compared between the two groups.Spearman correlation was used to analyze the correlation between frailty degrees and program of anticoagulant therapy.Two-class Logistic regression models were used to analyze the related factors for programs of anticoagulant therapy. Results: The incidence of the frailty syndrome was 56.49% in 131 elderly patients with atrial fibrillation.Compared with the anticoagulation group, non-anticoagulation group showed that the CFS score[(5.73±1.85)vs.(3.69±2.07), P<0.05], the incidence of the frailty syndrome(67.19% vs.46.27%, P<0.05)and Charlson index[(6.09±2.80)vs.(4.98±2.61), P<0.05]were increased.While, there was no significant difference in HAB-BLED score and CHA2DS2-VASc score between the two groups(P>0.05). The correlation analysis showed that there was a negative correlation between the application of anticoagulants and CFS grade in elderly patients with atrial fibrillation(r=-0.138, P<0.05). Multivariate Logistic regression analysis showed that age, CFS score and the incidence of frailty state were risk factors in elderly atrial fibrillation patients without the anticoagulant therapy(P<0.05). Conclusions The incidence of frailty state in elderly patients with atrial fibrillation is high, and the proportion of patients receiving the anticoagulant therapy is low.Age and frailty may be the most important influencing factors for anticoagulant therapy.Therefore, it is of great significance to incorporate frailty assessment into the management of anticoagulant therapy in elderly patients with atrial fibrillation.

Objective: To investigate the efficacy and outcome of transcatheter patent foramen ovale (PFO) closure in patients with cryptogenic stroke (CS). Methods: Sixty consecutive patients with cryptogenic stroke who undertook transcatheter PFO closure between May 2015 and September 2017 in Beijing Tiantan Hospital were enrolled in this prospective study.Transcranial Doppler (TCD) bubble test was performed and right-left shunt(RLS) was confirmed in all patients.Closure success rate,effective closure rate, complications, recurrence of ischemic stroke and new onset atrial fibrillation were evaluated. Results: A total of 60 patients (42 male,age range 24-68 (47±11)years) were included in the study.PFO size (motionless state) was (1.6±0.6)mm.RLS before closure was graded and 11 patients had moderate RLS and 48 patients had large RLS (include 41 patients who experienced shower or curtain effect).Closure success rate was 100% (60/60).No severe complications were observed.At 6 months,45 patients completed TCD bubble test.Of these, 4 patients suffered from moderate to large residual and thus effective closure rate was 91%(41/45).The mean follow-up period was 2-29 (median 12) months. During the follow-up, only 1 patient experienced recurrent cerebral infarction.New onset atrial fibrillation was not detected. Conclusion Transcatheter PFO closure is effective,safe and related with a good outcome in reduction of recurrent CS for patients with PFO.

Objective To reduce the cancer burden in the Jinchang cohort and provide evidence for developing cancer prevention strategies and performing effectiveness evaluation in the Jinchang cohort.We are fitting thirteen years of cancer mortality data from the Jinchang cohort by using six kinds of predicting methods to compare relative fitness and to select good predicting methods for the prediction of cancer mortality trends.Methods The mortality data of cancer in Jinchnag cohort from 2001-2013 were fitted using six kinds of predicting methods:dynamic series,linear regression,exponential smoothing,autoregressive integrated moving average (ARIMA) model,grey model (GM),and Joinpoint regression.Weight coefficients of combination models were calculated by four methods:the arithmetic average method,the variance inverse method,the mean square error inverse method,and the simple weighted average method.Results The cancer mortality was fitted and compared by using six kinds of forecasting methods;the fitting precision of the Joinpoint linear regression had the highest accuracy (87.64％),followed by linear regression (87.32％),the dynamic series (86.99％),GM (1,1) (86.25％),exponential smoothing (85.72％) and ARIMA (1,0,0) (81.98％),respectively.Prediction accuracy of the combination model derived from GM (1,1) and linear regression (＞99％) was higher than that of the combination model derived from ARIMA (1,0,0) and GM (1,1).The combination model derived from the GM (1,1) and linear regression,with weight coefficients based on the arithmetic average method and the mean square error inverse method,had the best prediction effect of the four weight calculation methods.Conclusion Prediction accuracy of the combination model,with accuracy ＞95％,was higher than that of the single prediction methods.

Objective To understand the dominant pathogens of febrile respiratory syndrome (FRS) patients in Gansu province and to establish the Bayes discriminant function in order to identify the patients infected with the dominant pathogens.Methods FRS patients were collected in various sentinel hospitals of Gansu province from 2009 to 2015 and the dominant pathogens were determined by describing the composition of pathogenic profile.Significant clinical variables were selected by stepwise discriminant analysis to establish the Bayes discriminant function.Results In the detection of pathogens for FRS,both influenza virus and rhinovirus showed higher positive rates than those caused by other viruses (13.79％,8.63％),that accounting for 54.38％,13.73％ of total viral positive patients.Most frequently detected bacteria would include Streptococcus pneumoniae,and haemophilus influenza (44.41％,18.07％) that accounting for 66.21％ and 24.55％ among the bacterial positive patients.The original-validated rate of discriminant function,established by 11 clinical variables,was 73.1％,with the cross-validated rate as 70.6％.Conclusion Influenza virus,Rhinovirus,Streptococcus pneumoniae and Haemophilus influenzae were the dominant pathogens of FRS in Gansu province.Results from the Bayes discriminant analysis showed both higher accuracy in the classification of dominant pathogens,and applicative value for FRS.

OBJECTIVETo understand the current status of the disease burden of liver cancer in Jinchang cohort.

METHODSAll the liver cancer death data from 2001 to 2013 and medical records of liver cancer cases from 2001 to 2010 in Jinchang cohort were collected for the analyses of the mortality, standardized mortality, potential years of life lost (PYLL) and working PYLL (WPYLL) associated with liver cancer. Spearman correlation and the average growth rate were used to analyze the trends.

RESULTSA total of 207 liver cancer deaths occurred in Jinchang cohort from 2001 to 2013, accounting for 16.68% of total cancer deaths. There were 259 liver cancer inpatients, accounting for 6.79% of the total cancer cases inpatients, in which 83 died (32.05%). Liver cancer death mainly occurred in males, accounting for 88.89%, and the liver cancer deaths in females accounted for 11.11%. The standardized mortality rate was 42.32/100,000 in males and 15.31/100,000 in females. The growth rate of liver cancer mortality was 5.62% from 2001 to 2013. Liver cancer deaths mainly occurred in age groups 60-69 years (26.57%) and 50-59 years (24.15%). The PYLL was 2906.76 person-years, the average PYLL was 14.04 years. The WPYLL was 1477.00 person-years and the average WPYLL was 7.14 years. The direct economic burden of liver cancer was 6270.78 Yuan per person, 301.75 Yuan per day. The average stay of hospitalization was 21.32 days.

CONCLUSIONThe mortality rate of liver cancer is increasing and the disease burden is still heavy.

BACKGROUNDHypertension (HTN) is a very prevalent public health problem and as the population ages, cognitive impairment (CI) is also going to be a public health burden. However, the relationship between hypertension duration and cognitive function declination worldwide is still unknown. The aim of the study was to investigate the effects of HTN duration on CI in Chinese population.

METHODSAt baseline, 1 386 HTN patients and 293 normotensive (NT) people were enrolled. The HTN patients were further divided into four subgroups (duration of HTN <6 years, 6-10 years, 11-20 years, and >20 years) according to the HTN duration and were screened for cognitive function with neuropsychological tests including mini-mental-state-examination (MMSE) and clock-drawing-test (CDT) in comparison with the NT group.

RESULTSMore HTN patients had CI (45.3%) than NT subjects (30.4%), and increased with HTN duration (P < 0.000 1). Compared with the scores of MMSE and CDT in the NT group, the declines were higher in the HTN patients (P < 0.000 1), and in the four HTN subgroups, both MMSE and CDT scores fall when the HTN duration increased (P < 0.05). Furthermore, in the HTN population without CI, the trend in alteration of CI was relatively mild but still existed (P < 0.05).

CONCLUSIONPeople with HTN are more likely to have CI and the possibility and aggravation increases the prolongation of HTN duration, both in amnesic and nonamnesic function.
