Exercise is one of the important techniques of cardiovascular rehabilitation. Exercise can reduce inflammatory response to improve endothelial function, and improve mitochondrial function to increase myocardial cell activity. For cardiovascular risk factors, exer-cise can promote the activity of lipoprotein, increase the level of high-density lipoprotein;improve the function of insulin receptor to reduce insulin resistance, reduce platelet aggregation and improve endothelial function to reduce blood pressure. For the respiratory system, aerobic exercise can improve the function of respiratory muscle, thus relieve the dyspnea. Exercise can promote the activation of immune factor and increase metabolism, to increase immune function and anti-aging. Resistance exercise can improve mitochondrial function and promote fi-ber type conversion, to improve the function of skeletal muscle system.

Currently,the toxicity study of traditional Chinese medicine is faced with the following problems. Firstly,the evaluation in vitro cannot fully reflect the true state of the body. Secondly,the traditional method is not sensitive enough to the early toxicity. Lastly,the toxicity evaluation indexes cannot determine whether the compatibility of traditional Chinese medicine produces toxicity or increases toxicity systematically. The paper proposed a synthesized early evaluation research method for target organ toxicity induced by traditional Chinese medicine:screening,validation,optimization and application. This method mainly inoolves early target organ toxicity biomarkers in screening,optimi?zation,validation,biological significance explanation,and application to the traditional Chinese medicine incompatibility based on the metabolic dynamic fingerprint spectrum in order to obtain biomarkers of target organ toxicity that are sensitive and precede conventional biochemical indices for early evaluation . We attempted to analyze the pattern of chang of the biomarkers for animals acted by″18 incompatible medicaments″compatibility combination. We found that Radix Aconiti Lateralis Preparata with cardiotoxicity were compatible with Rhizoma Pinelliae,and that Trichosanthes kirilowii Maxim,Fritillaria,Ampelopsis Radix and Bletilla striata without non-cardiotoxicity produced and increased cardiotoxicity systematically.

The Algerian medical health system provides free medical care. The incidence of non-communicable diseases, such as ischemic heart disease, stroke and Alzheimer’s disease, are high. Acupuncture has become a popular treatment recognized by the public with certain influence. However, some problems restrict the development of Traditional Chinese Medicine (TCM) in Algeria, like insufficient training of TCM talents; lack of TCM related knowledge, and medical insurance policy uncoving TCM. Based on the status quo of TCM, we suggested promotion and dissemination of TCM development in Algeria, including breaking through education limitation to expand the talent team, carrying out targeted publicity to expand the influence of TCM, promoting the inclusion of TCM in medical insurance and government legislative protection. Only in these ways, could we increase and expand the strength and scope of TCM influence, and promote the development of TCM in Algeria.

Innate immune cells are highly represented in the tumor microenvironment,and among the most abundant of these are macrophages.However,macrophages are broadly categorized as"classically activated"pro-inflammatory M1 macrophages and"alter-natively activated"anti-inflammatory M2 macrophages,which might be too simplified to describe the various phenotypes and func-tions of tumor-associated macrophages(TAMs).Most TAMs are now reclassified into CD68+TAM,CD163+TAM,CD204+TAM,CD169+TAM,and CCL18+TAM,among others,according to the different expression of surface proteins.These surface proteins have different types of ligands and regulate different signaling pathways and cytokines.Therefore,even if these subtypes of TAMs have similar ef-fects of promoting or inhibiting tumors,the mechanisms involved and the induced clinical manifestations are different.In this paper, the effects of various phenotypes of TAMs on tumor growth,metastasis,prognosis,and clinical relevance are reviewed.

Tai Chi and Qigong (TCQ) are regarded as major therapies of complementary and alternative medicine (CAM), and welcomed by increasing practitioners worldwide for their efficacy in various health issues. To better learn about the popularity of TCQ in the United States, the related data collected from 2007, 2012 and 2017 questionnaires of the National Health Interview Survey (NHIS) were examined and analyzed. The result showed that adult TCQ practitioners in the US increased substantially from 2007-2017, the percentage of Tai Chi practitioners in adult population was 1.0% in 2007, and Qigong practitioners 0.3%; Tai Chi practitioners was 1.1% in 2012, and Qigong practitioners 0.3%; in 2017, Tai Chi practitioners was 1.5%, and Qigong practitioners 0.5%. The top three reasons for using TCQ were: 82.4% for general wellness or disease prevention, 64.6% to improve or enhance energy, and 35.1% recommended by family, friends or co-workers. The health benefits of TCQ, the demand for complementary therapies and increasing research evidences were positive factors for the growth, while there are also challenges including insufficiencies in scientific researches and lacking of standardized teaching system. To promote the future development of TCQ in the US and oversea countries, we should optimize the research methods and standardize the teaching system, encourage the exchange and training of TCQ related professionals, and promote the integration of TCQ into conventional medical system and other related industries.
