Objective:To analyze the categories, scoring methods and effects of dietary patterns in heart failure patients, systematically.Methods:The databases such as Medline, Embase, and Cochrane were searched to obtain articles on dietary patterns of heart failure patients up to December 31, 2019. Arksey and O′Malley's scoping review method was applied to analyze the articles.Results:A total of 1 500 studies were identified, 21 of them met the inclusion criteria. These studies mainly studied Mediterranean diet(11 articles), Dietary Approaches to Stop Hypertension Diet(7 articles), Palaeolithic diet(1 article), low fat diet(1 article), High-protein Diet(1 article).Conclusions:The Mediterranean and DASH dietary patterns have a positive protective effect on heart failure disease prevention and treatment, but more randomized controlled trials are needed to improve the reliability of the conclusions.

Objective To study the diagnostic and predictive values of amino-terminal pro-B-type natriuretic peptide (NT-proBNP) in patients presenting acute dyspnea. Method A total of 533 patients with dyspnea were studied. According to the clinical characteristics and echocardiographic findings, the patients were divided into two groups, namely acute congestive heart failure group (ACHF) and non-ACHF group. NT-proBNP levels were assayed in all patients in order to evaluate the diagnostic value, and predictive value in patients of ACHF group by following up study to know the clinical destination of patients to be cardiac death or re-admission into hospital. Results There were 272 ACHF patients and 261 non-ACHF patients, and the levels of NT-proBNT were significantly different between two groups ( 2683.4±86.9) pg/mL vs. (238.6+8.7) pg/mL, P＜0.01) . A total of 220 patients were followed for 158 ±32. 8 days. The level of NT-proBNT in myocardium of patients in re-admission group was 2683 + 86. 9 pg/mL and in death group was 3283.4 + 105.7 pg/mL which both were higher than that in patients without cardiac events ( 1123. 5 + 72. 1 pg/mL) ( P ＜0. 01 ) . By using multivariate Cox analysis, log NT-proBNT was ( r = 0. 987, P = 0. 002), and atrial fibrillation (r = 0. 876, P = 0. 005 ) and ventriculat tachycardia ( r=0. 891, P =0. 005) were the valid predictors of cardiac events. Conclusions Routine determination of NT-proBNT in Emergency Department should be useful for quickly sorting patients with acute dyspnea. The NT-proBNT could be used as a good prognostic indicator of ACHF. In addition, log NT-proBNT and atrial fibrillation, ventricular tachycardia were the independent risk factors of cardiac events.

The alpha rhythm in electroencephalograph has been associated with the mental state of the brain. The aim of the present study was to analyze the complexity of the alpha activity in depression patients by Renyi entropy (RE) under two conditions, i.e., resting with eyes closed followed by a simple mental arithmetic. The EEGs were recorded in 20 depression patients and 20 age-matched control subjects. Results showed that the alpha activity of depression patients is more complex during resting and is more regular during the mental arithmetic than that of the controls. RE analysis can well characterize the alpha activity in depression patients and could be a valuable tool to study cognitive process and also a potential effective approach for the diagnosis of depression.

Objective Collecting the loosening periprosthetic interface-membrane, to discuss the mechanism of hip arthroplasty loosening. Methods The periprosthetic interface tissues of 29 hip arthroplasty revision cases from February 1995 to December 2003 were collected. The retrieved periprosthetic interface tissues were detected by immunohistochemistry. Some of them were studied by electronic microscope. Results (1)Transmission electronic microscope examination: the mitochondria swell. There were some substantia like lipid in the plasm of macrophages. Wear particles could be seen under scaning electronic microscope.(2)Immunohistochemistry: there were 22 IL-1? positive cases in cells of interface membrane. There were 29 IL-6 positive cases in cells of interface membrane. There were no positive results in TNF-? test. Conclusion (1)The wear particles of arthroplasty are important factors which cause biological reaction.(2)The interface membranes contain cytokine IL-1? and IL-6, which may play an important role in periprosthetic osteolysis and arthroplasty loosening.

Objective To observe the safety and efficacy of different periprocedural anticoagulation strategies in patients undergoing catheter ablation of atrial ifbrillation. Methods Eighty-five patients aged over 75 undergoing catheter ablation of atrial fibrillation from Jul 2011 to Nov 2013 were enrolled. They all took warfarin and transesophageal echocardiograms were performed to rule out left atrium appendage thrombus before ablation. They were divided into 3 groups. In Group 1 (30 cases), warfarin was stopped and bridged with low molecular weight heparin (LMWH) 3 days before procedure and LMWH bridging followed by warfarin alone after procedure. In Group 2 (32 cases), warfarin was continued during periprocedural period. In Group 3 (23 cases), Dabigatran or Rivaroxaban alone was used 4 hours after procedure respectively. Unfractionated heparin was used during procedure in all three groups. These three anticoagulation strategies were compared in bleeding, embolism events and other complications during 3-month follow-up. Results In Group 1, there were 1 new-onset ischemic stroke during hospitalization, 7 lower extremity hematomas, 1 subdural hemorrhage during 3-month follow-up and 6 minor bleeding events. In Group 2, there were 4 lower extremity hematomas and 4 minor bleeding events during 3-month follow-up. As for Group 3, only 2 lower extremity hematomas during hospitalization was observed in each without any minor bleeding events during follow-up. Conclusions Catheter ablation in elderly atrial ifbrillation patients was safe and effective in general. Compared with traditional anticoagulation strategy, continuing warfarin or novel oral anticoagulants could reduce bleeding complications without increasing thromboembolism risk.

Objective: To investigate the value of fibrinogen to albumin ratio (FAR) at admission on predicting spontaneous recanalization of infarct-related artery (IRA) in patients with acute ST-segment elevation myocardial infarction (STEMI). Methods: Clinical data from 255 acute STEMI patients ((61.1±11.2) years old, 189 males) who underwent emergency coronary angiography within 12 hours in our hospital from December 2015 to April 2018 were retrospectively analyzed. The acute STEMI patients were divided into non-spontaneous recanalization group (thrombolysis in myocardial infarction (TIMI) flow grade 0-1, 203 cases) and spontaneous recanalization group (TIMI flow grade 2-3, 52 cases). Multivariate logistic regression analysis was used to evaluate related factors of IRA spontaneous recanalization. The receiver operating characteristic (ROC) curve was used to evaluate the value of FAR in predicting spontaneous coronary recanalization. Results: There was no significant difference in age,gender, hypertension, diabetes, smoking,systolic blood pressure,diastolic blood pressure,heart rate, duration of chest pain, type of infarction, infarct-related artery, door-to-balloon time, and drug used before admission between non-spontaneous recanalization group and spontaneous recanalization group (all P>0.05). The FAR and high-sensitivity C-reactive protein levels were significantly lower in the spontaneous recanalization group than in the non-spontaneous recanalization group (8.20±1.85 vs. 11.02±2.75, P<0.001; (6.87±3.36) g/L vs. (8.51±3.72) g/L, P=0.004). Multivariate logistic regression analysis showed that FAR (OR=0.492, 95%CI 0.354-0.686, P<0.001), serum uric acid (OR=0.994, 95%CI 0.989-0.999, P=0.018) and high-sensitivity C-reactive protein (OR=0.774, 95%CI 0.614-0.975, P=0.030) were independent negative correlation with spontaneous recanalization of infarct-related artery in patients with acute STEMI. The ROC curve showed that the area under the curve of FAR predicting spontaneous recanalization of infarct-related artery in patients with acute STEMI was 0.807 (95%CI 0.630-0.758, P<0.001), and the diagnostic threshold was 9.26, the sensitivity was 76.9%, the specificity was 75.9%. Conclusion The level of admission FAR has certain predictive value for spontaneous recanalization of infarct-related arteries in patients with acute STEMI.

Varicella(chickenpox)is an acute infectious disease with high incidence in children. It is mainly transmitted through the airborne route and vaccination is the best measure for the prevention and control. Data from post-marketing studies show the effectiveness of varicella vaccines is 80%-85%, and two-dose regimen is significantly more effective than one-dose. After inclusion of varicella vaccines into the national immunization programme, there has been a clear decrease in varicella morbidity. Despite the lack of direct evidence, there remains the risk that varicella-zoster virus might latent in the dorsal route ganglia after vaccination. Therefore, more safe and effective novel varicella vaccines are under development. This paper reviewed the progress in varicella vaccine development and their long-term efficacy and safety.

Objective: To understand epidemiological characteristics of the pathogens and evolution of the genotype associated with infectious diarrhea epidemic caused by norovirus in Hebei Province. Methods: A total of 8 infectious diarrhea outbreaks caused by norovirus were reported from Jan 2015 to Dec 2016, of which epidemic treatment materials and specimens were collected at the same time. Norovirus nucleic acid was detected by using real-time PCR, and the partial ORF2 of the all positive specimens were amplified by RT-PCR and sequenced. Phylogenetic tree was constructed by using Mega5.2 based on partial ORF2 sequences of norovirus to perform phylogenetic analysis. Results: A total of 8 norovirus outbreaks, involving 265 cases who were mainly for residential inhabitents, children and students, were reported during this period, and the overall attack rate ranged from 0.70% to 8.13%. The overall positive detection rate of norovirus was 66.25%. The PCR products were sequenced, and sequencing result were obtained for 28 samples, which included GⅠ.3, GⅡ.2, GⅡ.4, GⅡ.13 and GⅡ.17. Conclusions Multiple genotypes of infectious diarrhea outbreaks caused by norovirus were found in Hebei province.

Objective: To evaluate the degree of trust of patients in community traditional Chinese medicine(TCM)physicians, based on the TCM service capability promotion program, and to analyze the impacts by TCM prevention and health care service. Methods: 1 391 patients at 22 primary health service centers in 3 cities from Zhejiang province were investigated using the Chinese version of Wake Forest Physician Trust Scale(WFPTS)in September, 2017. Quantitative and qualitative variables were described by mean±SD, and ratio respectively. Differences were compared by t test, ANOVA and Kruskal-Wallis test. Results: Chinese version of WFPTS had good reliability and validity in measuring community TCM physicians. The average scoring of patients′ trust in community TCM physicians was 38.00±6.42, while their benevolence and competence were 19.14±3.41, 18.82±3.50 respectively.For patients with different demographic characteristics, their quantity and the way to acquire and utilize TCM prevention and health care service had different degrees of trust in community TCM physicians. Patients′ gender, age, awareness and utilization of TCM prevention and health care service, etc. affect the degree of trust in community TCM physicians. Conclusions Patients have higher degree of trust in community TCM physicians, and improving the rate of awareness and utilization of TCM prevention has positive impacts on the degree of trust in these physicians. It is proposed that health knowledge education be strengthened and skills of community TCM physicians′ capacity be enhanced through various ways.
