Objective To investigate the correlation of uric acid(UA) level and the circadian rhythm of blood pressure in hypertensive patients. Methods Among the individuals who presented to the cardiology clinic, 70 patients who had hypertension and were diagnozed with non- dipper hypertension (non-dipper hypertension group) by 24 h ambulatory blood pressure monitoring (ABPM), 70 patients with dipper hypertension patients (dipper hypertension group), and 52 normotensive individuals (control group) were enrolled in this study. Peripheral venous blood samples were collected from all the patients in order to evaluate the hematological and biochemical parameters. All the assessed parameters were compared among three groups. Results The level of UA in non-dipper hypertension group was the highest, in dipper hypertension group was higher and in contrl group was the lowerst:(393.57 ± 53.52), (280.57 ± 41.64), (267.66 ± 59.38) μmol/L, and there were significant differences (P<0.01). Multivariate Logistic regression analysis revealed that the level of UA was an independent risk factor for non-dipper circadian rhythm of blood pressure (P = 0.003, OR = 2.26, 95% CI: 1.34- 3.89). Conclusions The higher level of UA may be a risk factor for non-dipper circadian rhythm of blood pressure in hypertension patients.

Objective To explore method of establishing and evaluating an asthma rat model with phlegm and blood stasis syndrome.Methods 60 SD male rats were randomly divided into 5 groups,a normal group,asthma group,combination of disease and syndrome(combination)group,DM group,and KCLW group,with 12 rats in each group.Asthma models were established using ovalbumin(OVA).A syndrome model of phlegm and blood stasis was established using a high-fat diet combined with the ice water bath method.We evaluated the asthma model through animal behavior observation,pathological section observation,inflammation index detection,and airway reactivity measurements.The phlegm and blood stasis syndrome model was evaluated via measurements of rat body mass,blood glucose,blood lipids,coagulation function,and hemorheological indexes and by observing symptoms and syndrome determination by Kechuan Liuwei mixture.Results(1)After OVA induction,the rats in the asthma model group and combination group showed symptoms such as shortness of breath,open mouth breathing,abdominal movement,restlessness,and irritability.HE staining showed the disordered arrangement of the bronchial mucosa in lung tissue,local detachment,thickening of the basement membrane and the bronchial tube wall,narrowing of the lumen,extensive infiltration of inflammatory cells,and congestion of capillaries.Compared with the normal group,the asthma model group and combination group(P＜0.05)had increased serum IL-4,IL-6,and TGF-β1.Penh values were increased after stimulation with various concentrations of Mch(P＜0.05).(2)Rats in the combination group showed symptoms such as chills,curling up with minimal movement,purple and dark claws,purple and black bruises on the tail,loose stools,and unclean perianal area.Compared with the rats in the asthma model group,rats in the combination group had increased body mass(P＜0.05)and blood glucose,triglyceride,and total cholesterol levels(P＜0.05),a shortened thrombin time(P＜0.05),increased fibrinogen content(P＜0.05),and significantly increased whole-blood viscosity at low,medium,and high shear rates(P＜0.05).The indexes were significantly improved after Kechuan Liuwei mixture administration.Conclusions The asthma rat model with phlegm and blood stasis syndrome can be established through OVA induction and high-fat diet combined with ice water bath.The model can be evaluated through behavioral observation,index measurements,and syndrome determination via formulas.

Objective To explore the knowledge and training needs of cardiopulmonary resuscitation (CPR) among a health checkup population, and to provide evidence for promoting cardiopulmonary resuscitation knowledge and skills at physical examination centers. Methods Using physical examination numbers, the random number table method was used to randomly select 1 000 people from a health checkup population, information collected including their basic information, cognitive status of cardiopulmonary resuscitation, and attitudes and behaviors toward cardiopulmonary resuscitation. The statistical analysis was performed using χ2test, a one-way ANOVA, and multivariate logistic regression analysis. Results Questionnaires was acquired from 997 consenting adult subjects. From which, 26% had received CPR training, and they demonstrated a low ratio of cognitive knowledge, scoring only 9.94 ± 6.36 (from a possible score of 30). Additionally, 92.1% had a willingness to learn CPR skills, and the CPR performance score was 23.12±3.27 (the highest score was 28). Unmarried people younger than 25 years old, professional and technical personnel, and military men had higher CPR scores than other groups. The CPR learning efficiency of military men, undergraduates, and people younger than 25 years old was higher than other groups. Older people had a lower willingness to learn cardiopulmonary knowledge and the better the feel-good status, the lower the willingness to learn CPR skills, of which OR values were 0.787 and 0.657, respectively (P<0.05). The rate of people learning CPR skills for relatives was higher than for strangers (P<0.05), and 83.8% were willing to receive medical training. Conclusion The health checkup population had a low cognitive level of CPR knowledge, and the willingness to learn CPR was high. To address this, free CPR training should be conducted at medical examination institutions.

Objective:To understand the current status of rare disease related health information release in WeChat official accounts in China.Methods:We used a series of key words containing "rare diseases" and the names of the top 30 rare diseases in hospitalizations in China to search WeChat official accounts. Eligible articles were selected by systematic sampling. All including WeChat official accounts and articles were evaluated to extract the basic information.Results:No relevant WeChat official accounts were found for 14 rare diseases (46.67 %). Most of the WeChat official accounts (52.17 %) were initiated by patients and patient groups. No significant difference was detected in the total number of articles between the official accounts related with Traditional Chinese Medicine (TCM) and non-TCM related ones, however, the frequency of the monthly information release was significantly higher in TCM related official accounts ( P<0.001), while the average reading number of articles was significantly higher in non-TCM related official accounts ( P<0.001). Nearly 80 % of the WeChat official accounts had navigation menu, and the average reading number of official accounts with menus was larger than those without menus. The top three topics were rare disease diagnosis and treatment knowledge (46.00 %), public welfare activity for rare diseases (12.81 %) and uncorrelated things (8.65 %), while the first three leading topics were cutting-edge information, public welfare activity and patient story, respectively. Conclusions:The scale for rare disease related health information release based on WeChat official accounts in China has been basically formed, but it is still in development stage. Many improvements should be made in their coverage of rare diseases, release frequency, topic and form. It is urgent to establish or recreate some high-quality WeChat official accounts in order to provide precise information and effectively facilitate the prevention and treatment of rare diseases.

This article has summarized the emergence and development of health life expectancy, classification of indexes, and commonly used measurement methods, as well as domestic and international application examples, and domestic research status. It proposes to establish a unified national measurement method, and make full use of big data resources in health care to comprehensively assess the health life expectancy of the population.

ObjectiveTo analyze the pharmacodynamic material basis of Hippophae Folium in the treatment of hyperlipidemia by network pharmacology and experimental verification. MethodThe hyperlipidemic HepG2 cell model induced by oleic and palmitic acid （molar ratio 2∶1） was established. The optimal concentration of Hippophae Folium containing serum was determined by cell counting kit （CCK）-8 method. The cells were intervened by the medicated serum， and oil red O staining was used to determine the success of the model. The contents of total cholesterol （TC） and triglyceride （TG） were determined by enzyme-linked immunosorbent assay （ELISA）. The possible mechanism of action was analyzed by network pharmacology， and molecular docking was performed to detect the binding ability of the potential targets. ResultCCK-8 assay showed that 10% medicated serum was the optimal concentration for cell growth. Oil red O staining proved that the hyperlipidemic cell model induced by oleic and palmitic acid has been built. After treatment with medicated serum， the contents of TG and TC decreased， indicating that Hippophae Folium had a good therapeutic effect on hyperlipidemia. Network pharmacology revealed that the core targets of Hippophae Folium in the treatment of hyperlipidemia were albumin （ALB）， peroxisome proliferative activated receptor γ （PPARγ） and matrix metalloprotein（MMP）-9， involving 755 biological processes， 73 molecular functions and 3 cellular components. By Kyoto Encyclopedia of Genes and Genomes（KEGG） analysis， it was found PPAR， hypoxia inducible factor（HIF）-1， AMP-activated protein kinase（AMPK） and other signal pathways were involved in the treatment of hyperlipidemia by Hippophae Folium. ConclusionHippophae Folium containing serum （10%） could reduce lipid accumulation and intracellular TG and TC levels in hyperlipidemic cell model， and its mechanism of action might be realized by activating PPAR signal pathway.
