Effect of Polygonati Rhizoma in improving pyroptosis injury of diabetic macroangiopathy via NLRP3/caspase-1/GSDMD pathway / 中国中药杂志

This study aims to explore the influence of Polygonati Rhizoma on the pyroptosis in the rat model of diabetic macroangiopathy via the NOD-like receptor thermal protein domain associated protein 3(NLRP3)/cysteinyl aspartate specific proteinase-1(caspase-1)/gasdermin D(GSDMD) pathway. The rat model of diabetes was established by intraperitoneal injection of streptozotocin(STZ) combined with a high-fat, high-sugar diet. The blood glucose meter, fully automated biochemical analyzer, hematoxylin-eosin(HE) staining, enzyme-linked immunosorbent assay, immunofluorescence, immunohistochemistry, and Western blot were employed to measure blood glucose levels, lipid levels, vascular thickness, inflammatory cytokine levels, and expression levels of pyroptosis-related proteins. The mechanism of pharmacological interventions against the injury in the context of diabetes was thus explored. The results demonstrated the successful establishment of the model of diabetes. Compared with the control group, the model group showed elevated levels of fasting blood glucose, total cholesterol(TC), triglycerides(TG) and low-density lipoprotein cholesterol(LDL-c), lowered level of high-density lipoprotein cholesterol(HDL-c), thickened vascular intima, and elevated serum and aorta levels of tumor necrosis factor-α(TNF-α), interleukin-1β(IL-1β) and interleukin-18(IL-18). Moreover, the model group showed increased NLRP3 inflammasomes and up-regulated levels of caspase-1 and GSDMD in aortic vascular cells. Polygonati Rhizoma intervention reduced blood glucose and lipid levels, inhibited vascular thickening, lowered the levels of TNF-α, IL-1β, IL-18 in the serum and aorta, attenuated NLRP3 inflammasome expression, and down-regulated the expression levels of caspase-1 and GSDMD, compared with the model group. In summary, Polygonati Rhizoma can slow down the progression of diabetic macroangiopathy by inhibiting pyroptosis and alleviating local vascular inflammation.

Pathogenesis and Treatment of Diabetic Macroangiopathy Based on Theory of Hidden Pathogen Damaging Collaterals / 中国实验方剂学杂志

The basic pathological change of diabetic macroangiopathy is atherosclerosis， and the metabolism legacy effect of hyperglycemia will cause continuous damage to the large vessels. Oxidative stress is a common mechanism for diabetes and its chronic complications and it is also the basis of the metabolism legacy effect which keeps damaging the large vessels. Anti-oxidant therapy can delay the course of diabetic macroangiopathy. According to the theory of traditional Chinese medicine （TCM）， the pathogenicity of hidden pathogen is concealing， lingering， and refractory. On the basis of the syndrome and treatment of collateral diseases， vessel-collateral theory， and hidden pathogen theory of TCM， the pathological changes of diabetic macroangiopathy are summarized as pathogen concealment-accumulation of sugar and lipids leading to phlegm and blood stasis-accumulation of toxins-damage to vessels and collaterals-hardening vessels. The core pathogenesis is the hidden pathogen damaging the collaterals， and the basic pathological change is vessel hardening. The toxins of sugar， lipid， phlegm， and stasis are the pathological products and the key to be treated. According to this theory， the medicinal materials with the functions of activating blood to dredging collaterals， resolving phlegm to clearing collaterals， Promoting qi to unblocking collaterals and removing toxins to shunting collaterals can be selected for prescription. These medicinal materials can inhibit the generation of reactive oxygen species， affect the oxidase activity， and enhance the antioxidant capacity， thereby regulating the oxidative stress response， protecting the vascular endothelial function， reducing the damage of the large blood vessels， and slowing down the progression of the disease. Such therapy is of great significance in clinical practice and research， providing a new idea for the prevention and treatment of diabetic macroangiopathy.

Influence of Endothelial Dysfunction on Diabetic Macroangiopathy： A Perspective from Theory of "Restraining Excessiveness to Acquire Harmony" / 中国实验方剂学杂志

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.

Early intervention with Di-Dang Decoction prevents macrovascular fibrosis in diabetic rats by regulating the TGF-β1/Smad signalling pathway / 中国天然药物

Macroangiopathy is a complication of Type II Diabetes Mellitus (T2DM), which is mainly caused by fibrosis of blood vessels. Using T2DM rat models, we investigated whether the traditional Chinese medicine, Di-Dang Decoction (DDD), exhibited anti-fibrotic actions on great vessels. T2DM rats were randomly divided into non-intervention group, early-, middle-, late-stage DDD intervention groups and control groups, including pioglitazone group and aminoguanidine group. After administration of DDD to T2DM rats at different times, we detected the amount of extracellular matrix (ECM) deposition in the thoracic aorta. The results showed that early-stage intervention with DDD could effectively protect great vessels from ECM deposition. Considering that TGF-β1 is the master regulator of fibrosis, we further validated at the molecular level that, compared to middle- and late-stage intervention with DDD, early-stage intervention with DDD could significantly decrease the expression levels of factors related to the activated TGF-β1/Smad signalling pathway, as well as the expression levels of downstream effectors including CTGF, MMP and TIMP family proteins, which were directly involved in ECM remodelling. Therefore, early-stage intervention with DDD can reduce macrovascular fibrosis and prevent diabetic macroangiopathy.

Effects of vitamin D3 supplementation combined with standardized hypoglycemic regimen on islet β cell function and macrovascular complications in newly diagnosed type 2 diabetes mellitus / 中华临床营养杂志

Objective To investigate the effects of vitamin D3 supplementation combined with standard-ized hypoglycemic regimen on islet β cell function and macroangiopathy of T2DM patients. Methods A total of 192 patients with type 2 diabetes mellitus were selected and randomly divided into control group and observation group with 96 patients in each group. Patients in two groups were given standardized hypoglycemic regimen, and the observation group was treated with vitamin D3 supplementation in addition. The changes of the indexes of body examination, glycolipid metabolism, islet β cell function and macrovascular complications before and 6 months after treatment were compared between the two groups. Results After 6 months of treatment, BMI, SBP, TG, FBG, FINS, HbA1c and HOMA-IR decreased, while HOMA-β increased in both groups ( P<0. 05) . Compared with the control group, the serum levels of 25 ( OH) D increased, and vaspin and CRP de-creased significantly after 6 months of treatment in the observation group ( P<0. 05) . CIMT and other indicators showed no significant difference. 25 (OH) D was negatively correlated with FBG, FINS, vaspin and CRP, and positively correlated with 1PH and ISI (P<0.05). Conclusion Vitamin D3 is closely related to T2DM and its macrovascular complications, but it has not been found that vitamin D3 supplementation can further improve islet β cell function and macrovascular complications in patients with T2DM.

Research progress of pigment epithelium-derived factor ,insulin resistance and type 2 diabetes / 中国糖尿病杂志

Pigment epithelium-derived factor (PEDF ) was originally found fromretinal pigment epithelium. It is confirmed that it plays an anti-angiogenic and apoptosis role in diabetic microangiopathy. Recently ,PEDF has been found to have a close relationship with insulin resistance ,type 2 diabetes and diabetic macroangiopathy. But the mechanism is unclear. More and more researches focused on its role in oxidative stress. PEDF may become a new target for diabetes and diabetic complication treatment and also a predictive factor for the disease.

Utility of different body composition for the predicting myocardial ischemia in the type 2 diabetes mellitus (T2DM) patients / 中华健康管理学杂志

Objective To explore the utility of different body composition for the prediction of myocardial ischemia in exercise in type 2 diabetes mellitus (T2DM) patients. Methods T2DM outpatients were selected from Jul. 2013 to Nov. 2014 (male 83, female 57) to measure body composition and clinical biochemical parameters, and divided them into two groups according to treadmill exercise testing results. Group A cases were positive (27 patients) and Group B cases were negative (113 patients). SPSS19.0 was used to make statistical analysis. Results (1) The age, gender, diabetes mellitus (DM) duration, medical history of hypertension and dyslipidemia, body mass index (BMI), waist circumference, the waist-hip fat ratio of the two groups had no significant difference (P>0.05). (2) The fasting blood glucose (FBG), glycosylated hemoglobin (HbA1c), total cholesterol (TC), triglycerides (TG), high density lipoprotein cholesterol (HDL-C) between the two groups had no significant difference. Compared with group B, the low density lipoprotein cholesterol (LDL-C) of group A [(2.48 ± 0.75) mmol/L vs. (2.81 ± 0.77) mmol/L, t=2.009, P<0.05] decreased significantly. (3) Overall body fat percentage, skeletal muscle weight of the two groups had no significant difference. Compared with group B, the waist-hip fat ratio (0.93±0.06 vs. 0.88±0.08, t=-2.790, P<0.01) andvisceral fat area [(99.47 ± 32.84) cm2 vs. (81.10 ± 25.47) cm2, t=-2.822, P<0.01] of group A increased significantly, while this difference mainly existed in male patients visceral fat area [(100.99±39.33) cm2 vs. (79.91 ± 27.09) cm2, t=-2.231, P<0.05], and waist-hip fat ratio was different in female patients of the two groups (0.91±0.06 vs. 0.85±0.09, t=-2.043, P<0.05) . Conclusion Abdominal obesity, especially visceral fat accumulation had close correlation with myocardial ischemia in exercise in T2DM patients. Waist-hip fat ratio and visceral fat area may be more effective indicators of myocardial ischemia in exercise in T 2DM patients than BMI.

Method: study of one hundred type 2 diabetic patients with/without diabetic macroangiopathy in their lower limbs; 36 were males and 64 females averagely aged 61.8 years (44-74 years). The level of hemoglobin glycosylation was quantitated as well as the reference value was estimated. The kind of association of this indicator with several risk factors and with the type of diabetic macroangiopathy was also established and described. Results: the reference value of 8.6 percent of the glycosylated hemoglobin was chosen because it was the cutoff point with the highest sensitivity (73.7 percent), specificity (83.7 percent) and probability odds (4.52) values. Poor glycemic control was confirmed in 48.3 percent of patients, mainly affected by occluded macroangiopathy (44.8 percent). In decompensated patients, dyslipidemia was the predominant risk factor (58.3 percent) along with the combination of smoking and blood hypertension (35.3 percent). Conclusions: the type 2 diabetic patients with occluded diabetic macroangiopathy of the lower limbs showed very high glycosylated hemoglobin values indicative of poor metabolic control(AU)

Alteraciones vasculares en ancianos de un área de salud de Santiago de Cuba / Vascular diseases in old men of a health area in Santiago de Cuba

Se realizó un estudio descriptivo y transversal de 65 ancianos pertenecientes al área de salud del Policlínico Docente "Armando García Aspurú" de Santiago de Cuba, de enero a mayo del 2012, con vistas a determinar las alteraciones vasculares en ellos mediante la prueba de la hiperemia reactiva con el fotopletismógrafo digital Angiodin. La asociación estadística entre las variables clínicas se estableció por la prueba de la Χ², con una significación menor de 0,05. Entre los resultados relevantes figuraron el grupo etario de 60 a 69 años (49,2 %) y el sexo femenino (72,3 %). Asimismo, la macroangiopatía predominó en 80,0 % de los ancianos, y no se mostró dependiente de la edad, aunque sí se mostró dependiente del sexo, donde los hombres fueron los más afectados. El factor de riesgo más frecuente fue la hipercolesterolemia, que fue dependiente de la prueba realizada, seguido del antecedente familiar de diabetes mellitus.

A descriptive and cross-sectional study of 65 old men, belonging to the health area of "Armando García Aspurú" Teaching Polyclinic in Santiago de Cuba, was carried from January to May, 2012, with the aim of determining the vascular diseases in them by means of the reactive hyperemia test made with the digital photoplethysmograph Angiodin® PD 3000. The statistical association among the clinical variables was settled down through the chi-squared test, with a significance lower than 0.05. Among the outstanding results there were the 60-69 years age group (49.2%) and the female sex (72.3%). Also, the macroangiopathy prevailed in 80.0% of old men, with no dependence on the age, although it was dependent on the sex, where men were the most affected ones. The more frequent risk factor was hypercholesterolemia that was dependent on the carried out test, followed by the familiar history of diabetes mellitus.

Implicación del traumatismo en la fisiopatología del pie diabético / Effect of traumatismo on the physiopathology of the diabetic foot

El pie diabético es el resultado de la interacción de factores sistémicos o predisponentes (neuropatía, microangiopatía y macroangiopatía), sobre los que actúan factores desencadenantes y agravantes. Con el objetivo de evaluar la implicación del traumatismo en la fisiopatología del pie diabético, se realizó una búsqueda bibliográfica en bases de datos nacionales e internacionales, se revisaron los trabajos hasta el 2011; los términos utilizados fueron: definición, concepto, traumatismo y fisiopatología del pie diabético, en idioma español e inglés. Se constató que el traumatismo en términos generales, solo es tratado en esta enfermedad como parte de los factores desencadenantes extrínsecos que se clasifican en mecánicos, térmicos o químicos; lo cual es avalado por cinco definiciones referidas a esta enfermedad. Se concluye que la limitada interpretación de la implicación del traumatismo en la fisiopatología del pie diabético, unida a una pobre interpretación de este factor en los diferentes conceptos conocidos, favorece la elaboración de una nueva definición de esta enfermedad.

The diabetic foot is the result of the interaction of systemic or predisposing factors (Neuropathy, Microangiopathy and Macroangiopathy) upon which unleashing aggravating factors also act. With the objective of evaluating the implications of traumatism in the physiopathology of the diabetic foot, literature review was made in national and international databases to analyze the papers published until 2011. The terms were definition, concept, traumatism and physiopathology of the diabetic foot in Spanish and English. It was verified that traumatism is generally addressed in this disease as part of the extrinsic unleashing factors that are classified into mechanical, thermal or chemical, which is supported on five definitions of this disease, one of them put forward by a domestic author. It was concluded that the restricted interpretation of the implication of traumatism for the physiopathology of the diabetic foot together with poor interpretation of this factor in the various concepts already known makes it possible to prepare a new definition of this disease.

Pattern of macrovascular disease phenotypes amongst newly diagnosed type 2 diabetic patients in a rural institute in Uttar Pradesh, India.

Background: The objective of current study was to determine the proportion of Macrovascular Disease (MVD) phenotypes amongst newly diagnosed type 2 diabetic patients in our institute by dividing the cases into sub-groups according to the MVD sites involved (NMVD - no macrovascular disease; NSCS - non-significant carotid stenosis; CBVD - cerebrovascular disease; CAD - coronary artery disease; PAD - peripheral artery disease; PVD - polyvascular disease) and studying the anthropometric, clinical and laboratory parameters in each group. Methods: The study included a cohort of 136 newly diagnosed patients with T2 DM. Demographic, clinical and laboratory parameters were included in analyses. Standardized procedures were used to assess the risk factors of associated metabolic syndrome (MetS). Results: The proportion of patients with MVD was 27.94% amongst the participants in the study. The majority of patients with MVD were in the CAD group (15.44%). Age, male sex and smoking history were independent risk factors in the CAD and PAD groups (P <0.01). A low HDL-C value was an independent risk factor in the CAD and PVD group P = 0.03). Very high frequencies of MetS were observed in the PAD and PVD groups (90% and 91.7% respectively). Prevalence of PVD was three times more common in males as compared to that in females. All patients with PAD had associated CAD also. Conclusion: This study projects a high proportion of MVD amongst newly diagnosed Type 2 diabetics in rural sub-population in Uttar Pradesh. High rates of mortality and morbidity in these patients due to macroangiopathy warrant early screening of MVD to ensure timely preventive and therapeutic measures.

Gene Chip Screening of Related Genes of Shenqi Compound Recipe in Preventing Diabetic Skeletal Muscle Disease / 广州中医药大学学报

Objective To investigate the correlation of diabetic skeletal muscle disease with macroangiopathy, and to explore the related genes of Shenqi Compound Recipe (SCR) in preventing and treating diabetic skeletal muscle disease by using gene chip technique, thus to reveal the molecular mechanism. Methods KKAy mice were fed with water containing nitri oxide synthase inhibitor of Nω-nitro-L-arginine methyl ester ( L-NAME) and high fat diet to induce the macroangiopathy complicated with type 2 diabetes. The experimental animals were divided into normal c57BL/GJ group, KKAy group, model group, SCR group (in the dosage of 14.4 g·kg-1·d-1) and rosiglitazone group ( in the dosage of 1.33 mg·kg-1·d-1) , 15 in each group. The medication groups were administered the corresponding agents for 8 consecutive weeks just as the modeling began. During the experiment period, blood glucose was monitored. At the end of the experiment, the abdominal aorta and skeletal muscle of mice were taken out for the observation of morphological changes, and differentially expressed genes of skeletal muscle between SCR group and model group, and between model group and KKAy group were detected by gene chip technique. Results SCR had an effect on relieving the atrophy, edema, fracture, and inflammatory changes in the skeletal muscle. There were 198 genes differentially expressed between model group and KKAy group, including 119 up-regulated genes and 79 down-regulated genes. There were 70 genes differentially expressed between SCR group and model group, including 33 up-regulated genes and 37 down-regulated genes. In the two comparison groups, 7 genes ( Celsr2, Rilpl1, Dlx6as, 2010004M13Rik, Anapc13, Gm6097, Ddx39b) showed reversed differential expression. Conclusion Diabetic skeletal muscle disease is associated with macroangiopathy. SCR has preventive effect on diabetic skeletal muscle lesion, and the mechanism may be related to the regulation of Celsr2, Rilpl1, Dlx6as, 2010004M13Rik, Anapc13, Gm6097, Ddx39b gene expression.

Early intervention of Didang Decoction on macroangiopathy in type 2 diabetic rats and its mechanisms / 中草药

Objective: To observe the effects of the early intervention with Didang Decoction (DDD) on macroangiopathy in type 2 diabetic rats. Methods: The type 2 diabetic rat model was established using high-fat diet and Streptozotocin (STZ), and the rats were divided into control, model, Pioglitazone (2.7 mg/kg), Simvastatin (1.8 mg/kg), early-, mid-, and late-term DDD-intervene groups (ig administered with 3.24 g/kg DDD once daily, before 4 weeks, at the same time, and after 4 weeks of STZ administration, respectively), the rats in each group were administered until 24 weeks of STZ administration. The immunohistochemical and pathological changes of intercellular cell adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1) in the aorta were observed, and the expression of nuclear factor-kappa B (NF-κB) and matrix metalloproteinases-9 (MMP-9) in aorta was detected using Western blotting. Results: Compared with the model group, the ICAM-1 expression decreased in early- and mid-term DDD-intervene groups, and Simvastatin group (P < 0.05), the VCAM-1 expression decreased in early-term DDD-intervene and Simvastatin groups (P < 0.05), the protein expression of NF-κB and MMP-9 was lower in early- and mid-term DDD-intervene groups (P < 0.05), and it is the most obvious in early-term DDD-intervene group. Conclusion: The contents of ICAM-1 and VCAM-1 as well as the protein expression of NF-κB and MMP-9 in type 2 diabetic rats decrease after early-term DDD-intervene, which could regulate NF-κB signaling pathway to delay the development of diabetic macroangiopathy.
