Coronary heart disease (CHD) and stroke are the most well-known cardiovascular diseases, which share many common pathological basis. Yindan Xinnaotong soft capsule (YDXNT) is a commonly used Chinese patent medicine in the treatment of stroke and CHD. However, its action of mechanism of co-treatment for stroke and CHD is still unclear. The aim of this study was to explore the common mechanism of YDXNT in co-treatment of CHD and stroke using network pharmacology, experimental verification and molecular docking. An integrated literature mining and databases of IPA, ETCM, HERB, Swiss Target Prediction, OMIM and GeneCards were used to screen and predict active ingredients and potential targets of YDXNT in co-treatment of CHD and stroke. The protein-protein interaction network, GO analysis and pathway analysis were analyzed by IPA software. The effect of YDXNT on core targets was verified by immunofluorescence. UPLC-QTOF/MS and molecular docking were used to screen and predict the main active constituents of YDXNT and their interactions with core targets. A total of 151 potential targets are predicted for YDXNT in co-treatment of CHD and stroke. Hypoxia-inducible factor-1α (HIF1α)-matrix metalloproteinase-9 (MMP9)-mediated HIF1α signaling pathway serves as one of the common mechanisms. YDXNT could reduce the increase of mitochondrial fluorescence intensity and the protein expression of HIF1α and MMP9 in HL-1 and HA induced by oxygen and glucose deprivation/reperfusion (OGD/R) in a dose-dependent manner. Baicalin may be the material basis for treating stroke and CHD with YDXNT. In conclusion, the HIF1α signaling pathway is one of the common key mechanisms of YDXNT in the co-treatment of stroke and CHD. The study provides support and basis for the in-depth scientific connotation of the traditional Chinese medicine theory of "same treatment to different diseases".

Phenylalanine ammonia lyase (PAL) can catalyze L-phenylalanine to produce trans-cinnamic acid, which is widely used in the fields of pharmacy, food and agriculture. In particular, phenylalanine ammonia lyase from Anabaena variabilis (AvPAL) is the only protein drug for the treatment of phenylketonuria. However, the poor activity and low stability limit the application in industry of AvPAL. In this study, the key amino acids of substrate-binding cavity in AvPAL were identified by screening the single site saturation mutagenesis library. Subsequently, the impact of replacing M222 with the additional 19 amino acids on activity was also evaluated by site-directed mutagenesis. It was found that the k_cat values of mutants M222L and M222V were 90% and 60% higher than that of AvPAL, and the k_cat/K_m was 1.4 and 1.5 times as that of AvPAL. Molecular docking results revealed that the higher activity of M222L and M222V may be due to the increase of hydrophobicity favorable for the substrate-binding cavity. This study is important for elucidating the structure-function relationship of AvPAL.

In the past 37 years, human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) has undergone various major transmission routes in China, with the world most complex co-circulating HIV-1 subtypes, even the prevalence is still low. In response to the first epidemic outbreak of HIV in injecting drug users and the second one by illegal commercial blood collection, China issued the Anti-Drug Law and launched the Blood Donation Act and nationwide nucleic acid testing, which has avoided 98,232 to 211,200 estimated infections and almost ended the blood product-related infection. China has been providing free antiretroviral therapy (ART) since 2003, which covered >80% of the identified patients and achieved a viral suppression rate of 91%. To bend the curve of increasing the disease burden of HIV and finally end the epidemic, China should consider constraining HIV spread through sexual transmission, narrowing the gaps in identifying HIV cases, and the long-term effectiveness and safety of ART in the future.

Objective To understand the prevalence and disease distribution of migrants within the water source area of the Middle Route Project of South-to-North Water Diversion Project and analyze the influencing factors. Methods By multi-stage stratified cluster sampling method, 307 immigrants and 676 immigrants were selected from Danjiangkou reservoir area, Shiyan city, Hubei Province. Results The prevalence of chronic diseases among in-migration was 51.8%. The prevalence rates of the top five chronic diseases were waist and leg pain, hypertension, gastritis, heart disease and diabetes. The prevalence of chronic diseases among out-migration was 65.1%. The prevalence rates of the top five chronic diseases were waist and leg pain, hypertension, gastritis, heart disease and bronchitis. The rate of chronic disease, the rate of two weeks and the rate of two weeks' visit were higher than that of emigration(all P<0.05). The results of multivariate analysis showed that the factors influencing the chronic diseases of immigrants were 60 years old (OR=59.928，P<0.001), unsatisfied family income (OR=0.377, P=0.002) and poor economic status (OR=0.517, P=0.028). The factors influencing the chronic diseases of immigrants were 60 years old (OR=26.190, P<0.001), smoking (OR=1.856,P=0.004), unsatisfactory family income (OR=0.598,P=0.029) and poor economic status (OR=0.460,P<0.001). Conclusions The prevalence of migrants within a high level is at a high level. Actually raising the income of immigrants is conducive to improving the health condition of immigrants.

With the development of integration process, how to manage citizens' cross-border healthcare be-tween member countries in an organized way has become a major agenda for European Union (EU). Through great efforts over years,a well-functioning mechanism has been established by EU's social health insurance and has been of global interest. It's believed that China's trans-provincial healthcare management can learn a lot from this mechanism. This study aims to provide experiences and reference to China's trans-provincial healthcare management by overview EU's mechanism for cross-border healthcare and then analyzing the differences between China and European Union in terms of object of management,authorization,service institutions,types of healthcare services,and reimbursement of medical insurance in different places. This study suggests that it's necessary for each province to officially introduce relevant policies in order to speed up and facilitate the establishment of trans-provincial healthcare management mech-anism. Moreover,to achieve orderly seeking medical treatment, health insurance agencies should be endowed with approval power to authorize patient trans-provincial application. Meanwhile, the network of health institutions which are entitled to provide services to trans-provincial patients should be expanded. Along with such expansion,and given the lack of understanding on behaviors of health institutions in different provinces for a specific local health insurance agency,it's required that national trans-provincial healthcare management system should take an active role in putting such health institutions under supervision.
