Abstract
The endophytes of medicinal plants play an important role in promoting the quality formation of the host. Therefore, this paper made a review of endophytes of medicinal plant Atractylodes lancea. According to previous studies, A. lancea boasts endophytes, such as fungi, bacteria, and actinomycetes, among which the beneficial microorganisms help the growth and development of A. lancea. There is a close interaction between the volatile oil of A. lancea and endophytes. Different endophytes vary in regulating the composition and content of the volatile oil of A. lancea, which might contribute to the quality formation of A. lancea. However, the information of the endophytic flora of A. lancea obtained by traditional culture and isolation is not enough to reflect the real situation of the endophytes of A. lancea. Little is known about the endophytes of A. lancea from different chemical types and different habitats, which is not conducive to the study of the ecological relationship between A. lancea and endophytes and limits the development and utilization of the endophytes. Therefore, at the end of this paper, the authors put forward suggestions for future research on endophytes in A. lancea, including:(1)mining the core endophyte resources of A. lancea by combining high-throughput sequencing with traditional culture and isolation;(2)exploring the relationship between the diversity of endophytes and chemical types of A. lancea;(3)strengthening the application of endophytes in A. lancea cultivation, in order to facilitate the cultivation efficiency and quality of A. lancea.

Abstract
The research on endophytes of medicinal plants mainly relies on the traditional culture and isolation methods. Because of their functions such as promoting host growth, improving stress resistance, promoting the accumulation of medicinal active ingredients or directly producing medicinal active ingredients, the endophytes of medicinal plants have gradually attracted wide attention. However, it was found that the strains isolated by traditional methods were not the true dominant endophytes of medicinal plants by comparing the results of traditional culture isolation with high-throughput sequencing. The blind and random nature of traditional methods leads to the lack of standards in terms of medium selection, culture time and interaction between species. On the contrary, high-throughput sequencing technology is an emerging molecular biology technology developed in recent decades. Due to its high resolution level and indepen-dent culture, it can be used for thorough analysis of the community structure and diversity of environmental microorganisms. Therefore, we proposed the strategy of using high-throughput sequencing technology to guide the traditional culture and isolation of endophytes from medicinal plants. Firstly, the endophytic structure and diversity of medicinal plants were completely clear by high-throughput sequencing technology, and the dominant endophytes of the host were unequivocal. Then according to the characteristics of each dominant endophytes design or query suitable medium for its growth to culture and isolation. Finally, the function of the isolates was studied. This method can prevent researchers from missing out on the important functional strains of the host, expand the research scope of endophytes of medicinal plants, and facilitate the in-depth excavation and utilization of endophytes of medicinal plants.

Abstract
Intercropping farming system is one of the essence of traditional agriculture in China and one of the most common and basic patterns of modern ecological planting. Intercropping system uses the principle of species diversity to create reasonable interspecific interaction conditions with obvious productivity advantages. In this paper, the interspecies interaction is divided into aboveground and underground parts from the space view, and its influence and mechanism on the yield and secondary metabolites of medicinal plants are elaborated.The interspecific interaction in the aboveground part mainly introduces the distribution and utilization of space resources among plants. The interspecific interaction in the underground part mainly introduces the soil rhizosphere effect and related mediating factors, root exudates, soil microorganisms, root space structure and soil environmental factors. On the basis of understanding the mechanism of interspecific interaction, this paper further discusses the application of intercropping in traditional Chinese medicine ecological agriculture, taking the effective control of diseases and insect pests, the increase of medicinal material yield and the improvement of medicinal material quality as the benefit index, so as to seek better advantages of intercropping and provide ideas for the utilization of intercropping production mode in traditional Chinese medicine ecological agriculture.

Abstract
This paper summarized the effects of ecological planting on secondary metabolism firstly and pointed out that ecological planting can increase the content of secondary metabolites in plants, especially the content of defensive secondary metabolites. The possible mechanism was analyzed subsequently. Then, we reviewed the induction and utilization of secondary metabolism in the ecological planting of Chinese materia medica from the perspectives of biological control of pests and diseases, promotion of beneficial microorganism accumulation, optimization of mixed planting, regulation of no-tillage and straw cover. In this article, we pointed out that paying close attention to secondary metabolism is the most important feature of ecological planting of Chinese materia medica. Ecological planting can promote the accumulation of secondary metabolites of Chinese materia medica which means can improve the quality of Chinese materia medica, beneficial to the prevention and control of diseases, insects and weeds. Furthermore, lacking of systemic researches,the extensive verifications and systematic in-depth researches on the ecological planting of Chinese materia medica should be carry out urgently.

Abstract
Numerous studies showed that the growth of medicinal plants in their native areas was simultaneously affected by abiotic stress combinations. Compared with single stress, plants have unique responses to a combination of different abiotic stresses and cannot be inferred directly from plants' responses to each individual stress. The effect of combined stresses on plants usually has three types of synergistic antagonism or independence. The secondary metabolism in the process of medicinal plant stress combination response also played a vital role, and environmental stresses can spur the accumulation of secondary metabolites, but under the stress combination, plants induce specific gene expression of key enzymes on secondary metabolic pathways, in turn, the accumulation of secondary metabolites against stress is formed. When plants are subjected to stress combination, the interaction of multiple signaling pathways makes it highly complex for plants to respond to stress combination. This paper summarized the effects of stress combination on physiological and secondary metabolism of medicinal plants, and discussed the related physiological, biochemical and molecular mechanisms. It provides theoretical basis for improving the adaptability of medicinal plants to adversity, improving the quality of Chinese medicinal materials, and further optimizing the cultivation of medicinal plants.

Abstract
Objective: The optimal operative strategy in patients with asymptomatic severe carotid artery stenosis undergoing coronary artery bypass grafting (CABG) is unknown. We sought to investigate the safety of carotid arterial shunting during simultaneous CABG and carotid endarterectomy (CEA). Methods: The clinical data of patients undergoing synchronous combined CEA and CABG in the First Hospital of China Medical University between March 2017 and July 2019 was retrospectively studied. Patients with asymptomatic severe carotid artery stenosis ≥70% according to NASCET (North American Symptomatic Carotid Endarterectomy Trial) were required CABG surgery. During conventional CEA, carotid arterial shunting was used in all cases. Results: Ten patients were recruited. The average clamping time of carotid artery was 5 minutes. The average follow-up time was 10 months. We did not observe stroke, cerebral hyper perfusion syndrome, death and carotid restenosis. Conclusions: Carotid arterial shunting during synchronous combined CEA and CABG was helpful for obtaining good curative effect.

Abstract
Rhizosphere bacteria play a vital role in plant nutrition absorption,growth and disease resistance. In this study,high-throughput sequencing technology was used to analyze the rhizosphere bacterial communities of Salvia miltiorrhiza and S. miltiorrhiza f. alba. Moreover,the function of dominant rhizosphere bacterial communities was analyzed. We found that Sphingobacteriales,Sphingomonadales and Nitrosomonadaceae were both dominant and specific bacteria in the rhizosphere of S. miltiorrhiza. The main functions of dominant rhizosphere bacteria communities in both species include promoting transformation of soil nutrients,improving plant immunity and ability of stress tolerance. This study was the first to compare rhizobacterial communities structure and function of S. miltiorrhiza and S. miltiorrhiza f. alba,which provided a new theoretical reference for studing the rhizosphere mechanism of healthy S. miltiorrhiza planting in the future.

Abstract
A novel Ti3Sn/NiTi shape memory alloy anode with a sandwich structure was fabricated by arc melting. In order to characterize in situ the Ti3Sn/NiTi anode microstructure changes and phase transformations during cycling, a nanoscale lithium battery was set up inside a transmission electron microscope, which consists of Li metal as the cathode, the native Li2O layer on the surface of Li metal as the solid electrolyte, and the Ti3Sn/NiTi as the anode. Only the Ti3Sn intermetallic compound experienced the electrochemical reaction, while the NiTi alloy (inactive with Li(+)) was applied for buffering the Ti3Sn volume change during cycling. An obvious reaction front of Ti3Sn migrated from one end to the other during lithiation, which can also return after delithiation. It provides direct evidence that the NiTi alloy can effectively accommodate the anode volume change during electrochemical lithiation and delithiation.

Abstract
OBJECTIVE To evaluate the effect of low molecular weight heparin (LMWH) and verus urokinase (UK) on unstable angina (UA). METHODS Sixty seven patients with UA were divided in two groups by a single blind, controlled, randomized method: LMWH (anti-thrombi) group and UK (thromblytic therapy) group. Total ischemia load in 24 hours ambulatory ECG, mortality and cases of acute myocardial infarction (AMI) in 30 days were employed to compare the effect and safety between two groups. RESULTS There was no significant difference in decreasing attacks of angina pectoris and total ischemia load between two groups. The UK group had two cases of AMI and five cases of complications of bleeding (two cases of epistaxis, two cases of bleeding gums, one case of hematochezia). CONCLUSION Antithrombin therapy is prior to thromblitic therapy, treatment of LMWH is safer than that of low dose UK in UA.

Abstract
OBJECTIVE This study was to evaluate the clinical features of acute myocardial infarction (AMI) in young and middle-aged patients. METHODS Eighty-seven patients were classified into two groups according to the age. Among them, 61 patients were 60 years old and above, 26 patients below 50 year old. Selective coronary artery angiography was performed on 68 cases and a scoring method which reflects the extent of narrowing of coronary artery was also used. RESULTS The older group had more risk factors than the young group. The angina pectoris in the young group was less than the older group. The incidence of acute heart failure in the young group was higher than the older group. The mortality of both two groups had no significant differences. CONCLUSION The high risk of AMI in the young and middle-aged patients should be paid more attention in the clinic.
