Metabolic diseases have seen a steady increase in incidence in recent years, becoming one of the main causes of sub-health status globally. Neutrophil extracellular traps(NETs) are reticular complexes containing DNA, which trap foreign microorganisms or induce an immune response. Current research indicates that NETs are widely active in various metabolic diseases and can cause severe damage to the body through multiple mechanisms, including promoting blood glucose elevation, damaging vascular endothelial cells, forming vascular embolisms, triggering intense inflammation, and promoting lipid accumulation. Therefore, intervening in NETs is an important approach to treating metabolic diseases. Research has shown a close relationship between the theory of spleen heat-turbid toxin theory and metabolic diseases-NETs mechanism. The basic pathogenesis include the internal accumulation of phlegm-dampness, qi stagnation and blood stasis, internal accumulation of dampness-heat, phlegm and blood stasis, and flourishing toxic heat. Various Chinese herbal medicines with the functions of dispelling dampness, resolving phlegm, promoting blood circulation to remove blood stasis, and clearing heat and toxins, along with their extracts and compound prescriptions, can treat metabolic diseases by regulating NETs and delaying disease progression. This paper systematically outlined the formation mechanisms of NETs, their connection to metabolic diseases, the theoretical basis in TCM, their roles in numerous metabolic diseases, and the current research status of TCM in regulating NETs to prevent and control metabolic diseases, aiming to provide effective reference ideas for developing therapeutic strategies for metabolic diseases.

Chaihu and Longgu Muli Decoction has demonstrated significant efficacy in the treatment of tachyarrhythmia accompanied by anxiety and depression. However, there is a lack of standardized guidelines for its clinical application. In this study, the Chaihu and Longgu Muli Decoction was investigated through extensive research on ancient and modern literature, as well as a collection of clinical medical records. The basic information, medication details, and diagnostic information from medical records, personal experience literature, and clinical cases in the treatment of tachyarrhythmia accompanied by anxiety were extracted and analyzed to preliminarily identify the prescription characteristics and syndrome patterns. Subsequently, the Delphi method was employed to construct an item pool based on the data obtained in the first step. An expert questionnaire was prepared to collect scores and revision opinions from experts regarding these items. After statistical analysis and group discussions, a second round of questionnaires was formed by screening out certain items. This process was repeated until a final item set for the treatment of tachyarrhythmia accompanied by anxiety with Chaihu and Longgu Muli Decoction was determined. These findings provided guidance for clinical prescription practices. By extracting 71 syndromes and signs, as well as 33 tongue and pulse characteristics, the main syndrome features included palpitations, chest tightness, irritability, etc., which were basically consistent with the ancient syndromes. Through frequency analysis and group discussions, 71 items were screened out. After screening, modification, and primary and secondary division, 11 main diagnostic items and 10 secondary diagnostic items were determined. On this basis, the research team believes that Chaihu and Longgu Muli Decoction is mainly indicated for the following syndromes in the treatment of tachyarrhythmia accompanied by anxiety(palpitations, poor sleep, bitter taste, dry mouth, irritability/easily angered/anxiety/fearfulness/easily startled, red tongue with greasy yellow coating, rapid pulse, high work/life pressure, tachyarrhythmia on electrocardiogram/Holter monitor, and positive results on anxiety scale). Secondary syndromes include chest tightness, shortness of breath, feeling heavy and weak in the body, sweating, poor appetite, constipation, greasy white tongue coating, wiry pulse, slippery pulse, or knotted and intermittent pulse.

Cellulose synthase (CesA), one of the key enzymes in the biosynthesis of cellulose in plants, plays an important role in plant growth and plant resistance. In this study, a total of 21 AsCesA genes from Aquilaria sinensis were systematically identified and the physico-chemical characteristics were analyzed based on genome database and bioinformatical methods. The phylogenetic tree was constructed and the gene location on chromosome, cis-acting elements in the 2 000 basepairs upstream regulatory regions and conservative motifs were analyzed. The AsCesA proteins were mainly located on the plasma membrane. The number of amino acids of the proteins ranged from 390 to 1 261. The isoelectric point distributed from 5.67 to 8.86. All of the 21 AsCesA proteins possessed the transmembrane domains, the number of which was from 6 to 8. The genes were classified into 3 groups according to the phylogenetic relationship. Obvious differences were observed in motif composition in genes from different groups. However, motif2, motif6, motif7 and motif10 were observed in all of AsCesA proteins. Analysis of cis-acting elements indicated that AsCesA genes family has cis-acting elements related to plant hormones, abiotic stresses, and biological processes. Seven AsCesA genes with differential expression were selected according to the calli transcriptome data induced by NaCl at different times and their expression levels under different abiotic stresses were analyzed by quantitative real-time PCR. The results indicated that salt, low temperature, drought, and heavy metal stresses could affect the expression level of AsCesA genes, and the abundance of AsCesA1, AsCesA3 and AsCesA20 showed a significant change, implying their potential important roles to the abiotic stresses. The accumulation pattern of cellulose content under different abiotic stresses was similar to the expression trend of AsCesA genes. Our results provide valuable insights into the role of cellulose synthase in A.sinensis in plant defense.

The normal function of vascular endothelial cells is an important foundation for maintaining vascular permeability， restricting inflammatory activities of the vascular wall， and balancing the coagulation and fibrinolytic system. Endothelial dysfunction caused by persistent damage from pathological factors is considered as an early and prominent event of diabetic macroangiopathy. In traditional Chinese medicine， the classical theory of "restraining excessiveness to acquire harmony" was originally a condensed generalization of the rule of generation， restriction， replacement and evolution in the natural world， revealing the internal regulation mechanism of the stable operation of things. Then it gradually evolved into an important rule to explain the physiological phenomena and pathological mechanism of human body and guide the treatment. Corresponding to the nature， the body homeostasis also requires to achieve a state of strong viscera function and inexhaustible Qi and blood generation under the rule of restriction and generation. The pathogenesis of diabetic macroangiopathy is the process of "the predominant one failing to restrict and the hyperactive one becoming harmful". The loss of restriction and generation of the five organs leads to powerless Qi transformation and， as a result， the Qi， blood and body fluid cannot be dispersed. Therefore， the Qi， blood and body fluid turn into phlegm and blood stasis， such as glucose and lipid metabolism disorder， oxidative stress， inflammatory response and high blood viscosity， and finally block the veins. Excessive phlegm and blood stasis cannot be resolved， instead they become harmful and invade the blood vessel， causing endothelial dysfunction and further resulting in diabetic macroangiopathy. Under the guidance of the theory of "restraining excessiveness to acquire harmony"， the method of "harmonizing viscera， eliminating pathogen and removing turbidity" can effectively regulate the function of vascular endothelial cells， thus playing a positive role in preventing and treating diabetic macroangiopathy. The mechanism may be related to reducing oxidative stress， inhibiting inflammation， limiting vascular smooth muscle proliferation， and reducing platelet adhesion.

The long-term existence of hyperglycemia leads to the occurrence of metabolic memory effect， which is an important reason for the formation of diabetic macrovascular disease， so the early control of metabolic memory is the key to the prevention and treatment of diabetes and its complications. The excessive formation of advanced glycation end products （AGEs） is not only an important factor to cause metabolic memory， but also the core mechanism for diabetic macrovascular disease. It is believed in traditional Chinese medicine（TCM） that Fu-xie （incubative pathogen） is the key pathogenesis of the formation of diabetic vascular diseases， and it is necessary to adopt the principle of removing pathogenic factors and opening collaterals as early as possible to prevent and cure the disease. During the Spring and Autumn Period and the Warring States Period， the theory of Fu-xie was germinated， and got mature in the Ming and Qing dynasties after the continuous development. The so-called Fu-xie means that the pathogens are of a potential nature but not cause diseases immediately. The theory of Fu-xie first appeared in Huangdi Neijing， with an original meaning of epidemic febrile disease occurring after incubation， and then its meaning continues to expand， now referring to all potential pathogenic factors that would not immediately cause diseases. As the cause and pathogenesis of many diseases， the theory of Fu-xie is widely used in clinical practice to guide the treatment of diseases. In the body， the accumulation of AEGs can induce the subsequent cascade effect in the body， and finally promote the formation and development of diabetic macrovascular diseases. This is very similar to the process of inducing metabolic disorder and disease in TCM due to the accumulation of phlegm and silt. Therefore， under the guidance of Fu-xie theory， the mechanism of AEGs in blocking metabolic memory and preventing and treating diabetic macrovascular disease was analyzed in this paper. On the one hand， it will provide a scientific basis for the exploration of Fu-xie theory affecting the disease course of diabetic macrovascular disease by regulating the generation of AEGs. On the other hand， it can also provide the material change basis for the development of Fu-xie theory in the occurrence and development of diabetic macroangiopathy.

Objective To determine the prevalence and distribution of type 2 diabetes mellitus (T2DM) and the relationship between maximum body mass index (MAXBMI) and T2DM. Methods From June to August, 2005, a stratified cluster sampling of 1071 permanent residents in communities, over 20 years old, from 4 districts and 1 county of Mudanjiang was chosen. The prevalence of T2DM, and the association between T2DM and different levels of the MAXBMI, current BMI were studied. Results The prevalence in the communities was 7.09% and in those with past maximum BMI≥28 kg/m~2, it was 12.10%. With the increase of past MAXBMI levels, the risk of T2DM patients also increased significantly(trend X~2=17.387 23, P<0.0001). Data from multifactor analysis showed that MAXBMI in the past was positively related to T2DM (OR=3.06, P=0.0013). In T2DM patients, the group with MAXBMI≥27.4 kg/m~2 had higher 2-hour postprandial blood glucose than those with lower MAXBMI (P=0.0408). When compared with low maximum BMI group in normal blood glucose population, the group with higher MAXBMI (≥ 25.4 kg/m~2) had higher blood glucose and greater change of BMI. Conclusion In both groups that patients with T2DM and with normal glucose, in order to control blood glucose better, researchers should not only concern about the influence of the MAXBMI in the past, but also pay attention to constantly keep BMI at the normal range.
