ObjectiveTo construct a standardized diagnostic scale for Qi-Yin deficiency with blood stasis syndrome in diabetic macrovascular disease. MethodsLiterature related to Qi-Yin deficiency with blood stasis syndrome in diabetic macrovascular disease was retrieved from CNKI， VIP， and Wanfang databases. Diagnostic information from four diagnostic methods was extracted and standardized， with items having a frequency of ≥15 included in the item pool. A three-round Delphi expert consultation was conducted， screening items using support degree， mean score， rank sum， and coefficient of variation. Item weights were determined using analytic hierarchy process （AHP）， gactor analysis （FA）， and combined weighting method （CWM）. The optimal weighting method was selected by comparing the area under the receiver operating characteristic （ROC） curve （AUC）. The Youden index was calculated to establish the diagnostic cutoff value， which was proportionally scaled. ResultsA total of 102 studies were included. Thirty-five items were incorporated into the item pool. The authority coefficients for the three Delphi rounds were 0.82， 0.85， and 0.86， with coordination coefficients of 0.648， 0.538， and 0.506， respectively. Fifteen items were retained after screening. ROC curve analysis showed the AUC ranking as FA > CWM > AHP. The maximum Youden index was 0.814， corresponding to a diagnostic cutoff of 8.361 （scaled to 40 points）. The final scale adopted a structured diagnostic framework： the symptom dimension requires at least 2 items， and the tongue or pulse dimension requires at least 1 category. ConclusionThis study developed a standardized diagnostic scale for Qi-Yin deficiency with blood stasis syndrome in diabetic macrovascular disease. Core items were screened via the Delphi method， with factor analysis identified as the optimal weighting method through AUC comparison. The diagnostic threshold （40 points） and structured diagnostic framework provide a quantitatively clear， clinically practical tool.

Based on advancements in modern medical research regarding the intricate connection between the endocrine and exocrine functions of the pancreas， as well as the relationship between pancreatic functions and traditional Chinese medicine （TCM） spleen system， this paper discussed the categorization of the pancreas. It is proposed that the pancreas is neither a true zang organ nor a fu organ， but possessed the attributes of an extraordinary fu-organ and can be classified under the spleen. The spleen governs transportation and transformation， ascent of the clear and dispersion of essence， which encompasses the endocrine and exocrine functions， and pancreatic enzymes and glucose-regulating hormones form the material basis for the spleen's function of dispersing essence. Diseases of the pancreas exhibit characteristics of both zang-organ deficiency and fu-organ excess， so treatment should simultaneously supplement zang-organ disease and regulate fu-organ disease when pancreas showing endocrine and exocrine co-morbidities， with focus on restoring the pancreas （spleen）'s dispersing essence function. Therapeutic strategies include supplementing spleen qi， nourishing spleen yin to strengthen spleen earth， unblocking spleen collaterals， raising spleen yang， and removing spleen turbidity to support the spleen's dispersing essence function， so as to replenish the essential qi of zang-fu organs， ensure their distribution throughout the body， and improve the endocrine and exocrine functions of the pancreas.

A systematic review of the traditional Chinese medicine （TCM） literatures published over the past decade on blood glucose fluctuations in diabetes mellitus was conducted to summarize related TCM research progress of theories and prescriptions， so as to provide references for future TCM theoretical exploration， basic research， and clinical prevention and treatment. Blood glucose fluctuation is an independent risk factor for chronic complications of diabetes mellitus， with significant progress made in TCM theories and prescription studies targeting this condition. The TCM theories include "spleen-pancreas homology"， "liver controlling dispersion"， "small intestine transforming qi and separating purity from turbidity"， "Yi Qi Zhou Liu theory"， "Xuan Fu Qi Ye theory"， "Yin-fire theory" and so on， all of which emphasize "Qi". Prescription studies primarily utilize clinical trials， which evaluate plentiful indexes of blood glucose fluctuation such as the mean amplitude of glycemic excursion. Classical and self-formulated prescriptions are widely used， with various dosage forms such as decoctions， granules and capsules. "Qi-Yin deficiency" is the main syndrome of blood glucose fluctuation. Basic research focuses on mechanisms that improve blood glucose fluctuation and reduce chronic complications， such as the renin-angiotensin system regulating islet β cell's function， and the transforming growth factor-β₁ inhibiting organ fibrosis. However， there are still some deficiencies in the evidential support and syndrome study of TCM theories， in the high-level evidence-based evaluation， efficacy comparison among multiple dosage forms， and the integration of TCM theories with prescription's clinical research， in the quantities， multi-level verifications， blood glucose fluctuation model establishment and intervention criteria as well as prescription-syndrome correspondence of prescription's basic research， and in the collaboration between clinical and basic research. Despite these challenges， TCM offers a promising approach to improving blood glucose fluctuation and reducing chronic complications in diabetes mellitus， with its rich theories， diverse methods， and proven efficacy.

Diabetic lower extremity arterial disease(DLEAD)is characterized by a low rate of diagnosis,low awareness,low treatment rate,high disability rate,and high mortality.Due to a lack of comprehensive prevention and treatment strategies or an integrated technological system,DLEAD has become a bottleneck in the prevention and control of diabetes mellitus at present.Traditional Chinese medicine(TCM)treatment of DLEAD offers the advantages of syndrome differentiation,evidence-based treatment,and holistic regulation.However,it lacks a comprehensive understanding of the through-course pathogenesis and unified standardized syndrome criteria.TCM treatment of DLEAD exerts multi-target and multi-pathway network effects,but the advantageous links are still not fully understood.TCM treatments can delay the onset and development of DLEAD,but the efficacy evaluation system remains incomplete.Furthermore,there is a lack of high-quality evidence-based medical evidence and clinical consensus and guidelines.Therefore,based on the idea of zhi wei bing,or treating the disease before it develops,in Chinese medicine,and focusing on the prevention and control of DLEAD,we have constructed a synergistic technical system that integrates traditional Chinese and Western medicine for the prevention and control of DLEAD.This system integrates prevention,diagnosis,treatment,mechanisms,and applications,so as to enhance the clinical effects of DLEAD prevention and control,and to create a new paradigm for collaborative traditional Chinese medicine and western medicine in the field of chronic disease management.

ObjectiveTo explore the distribution characteristics of traditional Chinese medicine （TCM） syndrome elements of macroangiopathy in patients with type 2 diabetes mellitus （T2DM） and the key elements of occurrence， development and progression of disease. MethodsA multicenter cross-sectional study was conducted to enroll 445 T2DM patients from five hospitals， and according to the presence or absence of macroangiopathy， the patients were divided into a T2DM group （120 cases） and a diabetic macroangiopathy （DM） group （325 cases）. Patients in DM group were divided into grade Ⅰ， Ⅱ， Ⅲ and Ⅳ according to the peripheral vascular color Doppler ultrasound results and the vascular anomalies classification standard. The general data including gender， age， duration of T2DM and body mass index （BMI） were collected， and the data of four examinations were obtained for syndrome differentiation. According to the diagnostic criteria of TCM syndrome elements， the patients can be divided into 9 patterns including qi deficiency， blood deficiency， yin deficiency， yang deficiency， qi stagnation， blood stasis， excess heat， and excess cold. The general data and distribution of TCM syndrome elements were compared between the two groups. The distribution of TCM syndrome elements in different vascular anomalies grades in the DM group was analyzed. Logistic regression analysis was used to explore the influence of various TCM syndrome elements on the occurrence of macroangiopathy in T2DM. ResultsThere was no significant difference in gender and BMI between groups （P＞0.05）. The age and duration of diabetes in the DM group were older and longer than those in the T2DM group （P＜0.01）. With the increase of age and prolonged course of disease， the severity of diabetic macroangiopathy increases gradually （P＜0.05 or P＜0.01）. There was no significant difference in BMI and course of disease among the different TCM syndrome elements （P＞0.05）. The average age of patients with blood stasis syndrome was the oldest （P＜0.05）. There was significant difference in gender distribution between the excess heat syndrome and yin deficiency syndrome （P＜0.05）. A total of 240 TCM syndrome elements were extracted from the T2DM group， while 731 TCM syndrome elements extracted from the DM group. The top two high-frequency syndrome elements in the two groups were qi deficiency and yin deficiency， with a frequency of larger than 50%. The distribution of phlegm-damp syndrome and blood-stasis syndrome were significantly higher in the DM group than in the T2DM group （P＜0.01）. There were significant differences in the distribution of qi deficiency syndrome， yin deficiency syndrome， phlegm-damp syndrome， blood stasis syndrome， and excess heat syndrome among different grades of vascular anomalies （P＜0.01）； qi deficiency and yin deficiency were both high-frequency TCM syndrome elements in patients at grades 0 to Ⅲ； phlegm-damp syndrome increased in frequency with the progression of the disease from grades 0 to Ⅳ， and the frequency of blood stasis syndrome showed an overall upward trend. The frequency of phlegm-dampness syndrome increased from grades 0 to Ⅳ with the progression of the disease， and the frequency of blood stasis syndrome showed an overall upward trend. Logistic regression analysis showed that phlegm-damp syndrome and blood stasis syndrome were important TCM syndrome elements related to the vascular anomalies degree of macrovascular disease in T2DM （P＜0.05 or P＜0.01）. ConclusionQi deficiency and yin deficiency are the basic TCM syndrome elements throughout the whole process of T2DM and diabetic macrovascular disease. Phlegm-damp and blood stasis are related to the degree of vascular anomalies in diabetic macrovascular disease and are the key TCM syndrome elements in the progression of macroangiopathy in T2DM.

First recorded in Huangdi Neijing, "drinking little but urinating much" is the main symptom of "Feixiao", of which the pathogenesis is heart transferring cold to lung. Many later traditional Chinese medicine doctors have worked and brought different expositions on the disease's name, "Shangxiao", "Xiaxiao", "Feixiao" or "Shenxiao" are used respectively. In regard to the pathogenesis, dryness-fire, simultaneous occurrence of cold and heat or deficiency-cold are supposed to be the main properties of the disease, while heart, lung, liver, and kidney are the core disease locations. For example, YU Jiayan emphasized "dryness-heat in heart and lung", ZHENG Qin'an advocated "wind-fire of Jueyin", ZHANG Congzheng expounded "cold with heat in the heart and lung", LOU Ying revealed "cold with heat in the lung and kidney", and HUANG Yuanyu proposed " cold in kidney with dampness in spleen". By analyzing the theories of different schools of traditional Chinese medicine and related prescriptions or herbs and medical records, "drinking little but urinating much" could be attributed to "Shenxiao", and "deficiency-cold in lung and kidney" could be its basic pathogenesis, and meanwhile the cross-transmission of zang-fu viscera, intermingled deficiency and excess as well as inter-transformation between cold and heat should be considered adequately. This paper summarizes and sorts out the theories of "Xiao" disease in ancient literature, so as to provide new ideas for the modern prevention and treatment of diabetes.

In western medicine， the small intestine anatomically belongs to the digestive system and is also an important immune organ of the body. The innate immune system of the small intestine consists of a tissue barrier， innate immune cells， and innate immune molecules. The dysfunction of any part can cause metabolic disorders and eventually lead to diabetes. In the pathogenesis of diabetes， traditional Chinese medicine （TCM） has the theory of ''spleen deficiency causing diabetes''， which points out that the impaired spleen function results in inadequate transformation， impaired essence spread， and turbidity by essence accumulation， which is the core pathological link of blood glucose metabolism disorder in diabetes. In terms of the relationship between the small intestine and the spleen， the theory of TCM holds that the small intestine is located in the abdomen and the abdomen is dominated by the spleen. The digestion， absorption， and endocrine functions of the small intestine are also similar to the functions of spleen in governing movement and transformation and spreading essence by virtue of spleen Qi. Therefore， the anatomical and physiological functions of the small intestine in western medicine are closely related to the spleen in TCM. At the same time， the spleen is closely related to the innate immune function of the small intestine in TCM. The spleen participates in the generation and distribution of defense Qi， and the process of defense Qi playing the external function is similar to the process of the activation of the innate immune response. The spleen is also an important organ involved in fluid metabolism， which can cooperate with the lung and kidney to timely remove turbid fluid from the body. It can also work with the stomach as the hub of Qi ascending and descending and regulate the physiological activities of "clear Yang" and "turbid Yin"， so as to ensure the homeostasis of the internal environment of the body， which is the basis for maintaining the normal function of the innate immunity of the small intestine. Therefore， taking "spleen deficiency causing diabetes" as a bridge， the theory of TCM and western medicine were combined to explain the relationship between small intestinal innate immunity imbalance and the pathogenesis of diabetes from the perspective of TCM， which is helpful to understand the pathogenesis of diabetes in a deeper level and also provide a new perspective and new way for the prevention and treatment of this disease with TCM.

Atherosclerosis （AS） is a chronic inflammatory pathological process in which lipid and/or fibrous substances are deposited in the intima of arteries， and it is one of the pathological bases of many cardiovascular and cerebrovascular diseases. Endoplasmic reticulum stress （ERS） is a protective mechanism of cell adaptation. Moderate ERS can reduce abnormal protein aggregation and increase the degradation of misfolded proteins to repair and stabilize the internal environment， while excessive ERS can cause unfolded protein reaction， activate inflammation， oxidative stress， apoptosis， autophagy， and other downstream pathways， and lead to cell damage， or even apoptosis. A large number of studies have shown that ERS mediates a variety of pathological processes related to AS， affects endothelial cells， smooth muscle cells， macrophages， endothelial progenitor cells， and other cell components closely related to its occurrence and development， influences the progress of AS by regulating cell function， and promotes the formation of AS plaque， the transformation of stable plaque to unstable plaque， and the rupture of unstable plaque. Regulation of ERS may be a key target for the prevention and treatment of AS， and it is a research hotspot at present. Traditional Chinese medicine （TCM） believes that the origin of AS is the imbalance of Yin and Yang， the disharmony of Zangfu organs， and the abnormal operation of Qi， blood， and body fluid， which leads to the accumulation of phlegm， blood stasis， and other pathological products in the pulse channels， making the blood flow blocked or misfunction and causing the disease， which belongs to the syndrome of deficiency in origin and excess in superficiality. As the pathogenesis of AS is complex， and the symptoms are diverse， TCM has significant advantages in treating AS because of its multiple targets， multiple pathways， stable efficacy， strong individualization， and high safety. This paper systematically elaborated on the role of ERS in the occurrence and development of AS and summarized the mechanism research on the regulation and control of ERS by Chinese herbal monomer， Chinese herbal extract， Chinese herbal compound， and proprietary medicine， so as to provide a theoretical basis for clinical research and drug development in the prevention and treatment of AS.

Diabetic nephropathy （DN） is one of the serious and common microvascular complications of diabetes mellitus （DM） and the main cause of end-stage renal disease （ESRD）. Endoplasmic reticulum stress （ERS） is a common stress defense mechanism in eukaryotic cells. In the ERS state， cells activate the unfolded protein response （UPR） to enhance the folding of unfolded proteins and the degradation of misfolded proteins， so as to restore the normal physiological function of the endoplasmic reticulum and avoid cell damage. However， excessive or chronic persistent ERS can induce apoptosis， inflammation， oxidative stress and other pathways to eventually cause cell damage. In recent years， a large number of studies have confirmed that ERS is closely associated with the occurrence and development of DN. In the case of DN， ERS is involved in the damage or protection of podocytes， glomerular mesangial cells， renal tubular epithelial cells， and glomerular endothelial cells. The regulation of ERS has become one of the hotspots in the prevention and treatment of DN and has received extensive attention in the field of traditional Chinese medicine. This paper systematically expounds the role of ERS in the occurrence and development of DN and summarizes the ERS-targeted regulation of DN by traditional Chinese medicine， with a view to providing certain research ideas for the prevention and control of DN with traditional Chinese medicine.

Diabetic cardiomyopathy （DCM） is one of the complications of diabetes. It refers to a specific type of idiopathic cardiomyopathy that occurs in individuals with diabetes， distinct from other cardiovascular diseases such as coronary heart disease， valvular heart disease， or congenital heart disease. It has also been identified as one of the leading causes of death in diabetic patients for many years. Research has shown that the pathogenesis of DCM is closely associated with insulin resistance， activation of various inflammatory responses， increased oxidative stress， impaired coronary microcirculation， and accumulation of advanced glycation end products （AGEs）. Among various inflammatory responses， the activation of the NOD-like receptor protein 3 （NLRP3） inflammasome can induce the secretion of a large amount of pro-inflammatory cytokines through the cascade reaction of inflammation， subsequently mediating cellular pyroptosis and promoting myocardial damage. Currently， extensive experimental studies on traditional Chinese medicine （TCM） have been conducted in China and abroad based on the significant role of the NLRP3 inflammasome in the prevention and treatment of DCM. These studies have demonstrated that Chinese medicinal extracts， such as Astragalus polysaccharide and ginsenoside Rb₁， single drugs like Coriolus and Cordyceps， and Chinese medicinal formulas like Didangtang and modified Taohe Chengqitang， as well as acupuncture and TCM exercise therapy， can regulate the relevant pathways of the NLRP3 inflammasome to inhibit its assembly or activation， reduce inflammatory responses， inhibit myocardial remodeling in DCM， and improve cardiac function. This article reviewed the relationship between the NLRP3 inflammasome and DCM， as well as the research progress on TCM in exerting anti-inflammatory effects in this field， aiming to provide new insights for the development of therapeutic approaches for DCM.
