ABSTRACT
SUMMARY: Coreopsis tinctoria Nutt. (C. tinctoria Nutt.) can protect diabetic kidneys, but the mechanisms are unclear. This work is to investigate the potential mechanisms of C. tinctoria Nutt. in the treatment of diabetic nephropathy based on network pharmacology analysis of its active ingredients. Twelve small molecular compounds of C. tinctoria Nutt. and targets related to diabetic nephropathy were docked by Discovery Studio 3.0. DAVID database was used for GO enrichment and KEGG pathway analysis. Cytoscape 3.6.1 was used to construct active ingredient-target network. Cell viability was detected with MTT. Glucose consumption was analyzed with glucose oxidase method. Protein expression was measured with Western blot and immunofluorescence. Electron microscopy observed autophagosomes. The core active ingredients of C. tinctoria Nutt. included heriguard, flavanomarein, maritimein, and marein. Twenty-one core targets of the 43 potential targets were PYGM, TLR2, RAF1, PRKAA2, GPR119, INS, CSF2, TNF, IAPP, AKR1B1, GSK3B, SYK, NFKB2, ESR2, CDK2, FGFR1, HTRA1, AMY2A, CAMK4, GCK, and ABL2. These 21 core targets were significantly enriched in 50 signaling pathways. Thirty- four signaling pathways were closely related to diabetic nephropathy, of which the top pathways were PI3K/AKT, insulin, and mTOR, and insulin resistance. The enriched GO terms included biological processes of protein phosphorylation, and the positive regulation of PI3K signaling and cytokine secretion; cellular components of cytosol, extracellular region, and extracellular space; and molecular function of protein kinase activity, ATP binding, and non-membrane spanning protein tyrosine kinase activity. In vitro experiments found that marein increased the expression of phosphorylated AKT/AKT in human renal glomerular endothelial cells of an insulin resistance model induced by high glucose, as well as increased and decreased, respectively, the levels of the microtubule-associated proteins, LC3 and P62. C. tinctoria Nutt. has many active ingredients, with main ingredients of heriguard, flavanomarein, maritimein, and marein, and may exert anti-diabetic nephropathy effect through various signaling pathways and targets.
RESUMEN: Coreopsis tinctoria Nutt. (C. tinctoria Nutt.) puede proteger riñones diabéticos, sin embargo los mecanismos son desconocidos. Este trabajo se realizó para investigar los potenciales mecanismos de C. tinctoria Nutt. en el tratamiento de la nefropatía diabética basado en el análisis de farmacología en red de sus principios activos. Doce compuestos moleculares pequeños de C. tinctoria Nutt. y los objetivos relacionados con la nefropatía diabética fueron acoplados por Discovery Studio 3.0. La base de datos DAVID se utilizó para el enriquecimiento GO y el análisis de la vía KEGG. Se usó Cytoscape 3.6.1 para construir una red de ingrediente-objetivo activa. La viabili- dad celular se detectó mediante MTT. El consumo de glucosa se analizó con el método de glucosa oxidasa. La expresión proteica fue determinada mediante Western blot e inmunofluorescencia. En la microscopía electrónica se observó autofagosomas. Los principales ingredientes activos de C. tinctoria Nutt. incluyeron heriguard, flavanomarein, maritimin y marein. Veintiún de los 43 objetivos potenciales fueron PYGM, TLR2, RAF1, PRKAA2, GPR119, INS, CSF2, TNF, IAPP, AKR1B1, GSK3B, SYK, NFKB2, ESR2, CDK2, FGFR1, HTRA1, AMY2A, CAMK4, GCK y ABL2. Estos 21 objetivos principales se enriquecieron significativamente en 50 vías de señalización. Treinta y cuatro vías de señalización estuvieron estrechamente relacionadas con la nefropatía diabética, de las cuales las principales vías fueron PI3K/ AKT, insulina y mTOR, y resistencia a la insulina. Los términos GO enriquecidos incluyeron procesos biológicos de fosforilación proteica, la regulación positiva de la señalización de PI3K y la secreción de citoquinas; componentes celulares del citosol, región extracelular y espacio extracelular; y la función molecular de la actividad de la proteína quinasa, la unión de ATP y la actividad de la proteína tirosina quinasa que no se extiende por la membrana. Los experimentos in vitro encontraron que la mareína aumentaba la expresión de AKT/AKT fosforilada en células endoteliales glomerulares renales humanas en un modelo de resistencia a la insulina inducida por niveles elevados de glucosa, así como aumentaron y disminuyeron respectivamente, los niveles de las proteínas asociadas a los microtúbulos, LC3 y P62. C. tinctoria Nutt. tiene muchos principios activos, con ingredientes principales de heriguard, flavanomarein, maritimain y marein, y puede ejercer un efecto de nefropatía antidiabética a través de distintass vías de señalización y objetivos.

@#Objective To introduce a novel classification method for pectus excavatum. Methods A retrospective review of 569 operative patients with pectus excavatum between January 2015 and September 2017 in our hospital was performed. The malformations were described and classified from three dimensions: symmetry (abbreviated as S), depth (abbreviated as D) and position (abbreviated as P). The final integral was calculated according to the deformity index, so that the severity of the deformity could be evaluated. All patients underwent Nuss or modified Nuss surgery. Results All pectus excavatum deformities were classified into 24 types. The most common type was S1D2P1, accounting for 27.2% of the total patients followed by S1D2P2, S1D1P2 and S2D2P2, accounting for 12.0%, 11.6% and 11.4% of all patients respectively. S1D3P3, S1D3P4 and S2D3P3 were not found in our patients. According to the integral, 321 patients were mild, 23 severe, and the rest were moderate. The appearance of all patients improved after the operation. Among them, 405 patients were implanted with a plate, 159 with two plates and 5 with three plates. The length of hospital stay was 5-12 d, with an average of 7.3±1.5 d. Conclusion This classification method is a more comprehensive classification, but its scientific and practical characteristics need to be further confirmed.
ABSTRACT
@#Objective To introduce an integral classification method of thoracic deformity. Methods From March 2015 to March 2017, 869 patients with thoracic deformity were observed. The patients were classified according to the traditional classification method at first, and then were classified according to the integral classification method. According to the standard plane of the normal chest wall, the chest deformities were classified into types Ⅰ and Ⅱ: those below the plane belonged to type Ⅰ, and those above the plane belonged to type Ⅱ. Then two types were divided into subtypes Ⅰ-a, Ⅰ-b, Ⅰ-c, Ⅰ-d, Ⅰ-e, Ⅰ-f, Ⅰ-g and Ⅱ-a, Ⅱ-b, Ⅱ-c, Ⅱ-d according to the specific characteristics of malformation. Results There were 840 patients included in the classification system, accounting for 96.7% of the total patients, and the remaining 29 (3.3%) were complicated malformations, which could not be accurately described by using a single classification type. Compared with the traditional classification methods, patients with pectus excavatum and pectus carinatum were divided into different subtypes. Poland syndrome did not exist any longer, and Dove chest alone became the type Ⅱ-c. Conclusion Integral classification method is a simple and practical classification method. Since the method directly depends on the characteristics of malformation which is related to the operation, it plays a guiding role in the operation. But its superiority needs to be further confirmed.
