[Rationality analysis of clinical application of Danhong injection in affiliated hospital of Nanjing university of Chinese medicine from 2013 to 2014].

It is necessary to investigate the influence of the rationality of clinical drug use on the benefit and risk factors of traditional Chinese medicine injections. The retrospective survey was based on the medical records and information of 4 950 patients who used Danhong injection in the HIS database of the first affiliated hospital of Nanjing University of Chinese Medicine from 2013 to 2014. The basic statistical methods and associated rules analysis were utilized to analyze the HIS information of these patients, including the basic information, the diagnosis, the department, the dosage, the usage of medication, the drug combination and the adverse reactions. And the rationality analysis of the clinical application of Danhong injection was carried out to investigate relevant factors of the adverse reactions. The results showed that most cases came from the department of cardiology (51.95%) and encephalopathy center (20.67%). In the statistical period, the patients aged above 40 years old accounted for 96.65%. And the two western medicine diagnosis items with the highest confidence level were coronary heart disease and angina pectoris (97.15%), while the three items were coronary heart disease, angina pectoris and hypertension (97.02%). The irrational indications were mainly hypertension (12.93%) and diabetes (4.55%). All of them were diagnosed as blood stasis syndrome by the traditional Chinese medicine. About 98.93% of the single dosage was within the range stipulated on package insert, the duration mainly ranged between 1 and 21 days, and 97.64% of the menstrua contained 0.9% NS and 5% GS. According to the medication records,99.26% were the use of combined drugs, with 8.41 drugs on average. Antiplatelet drugs (72.04%) were the most frequently combined with western medicine, followed by the cholesterol-regulating drugs (64.86%) and the cerebrovascular drugs (60.26%). When used in the combination with antibiotics for the infection, cephalosporin antibiotics were the most frequently applied (8.81%). When used with traditional Chinese medicines, traditional Chinese medicines for activating blood circulation and removing blood stasis or monomer traditional Chinese medicine injections (28.93%) were the dominance, in which Gastrodin injection was the most frequently applied (16.23%). And 12 cases of adverse reactions were reported, with the ADR rate of 0.24%. The indications, solvent compatibility and irrational drug combination may be the potential risk factors for ADRs induced by Danhong injection. Further experiments are required to evaluate the benefits and risks in these three aspects.

Desarrollo de un proceso tecnológico a escala de laboratorio para la extracción de polifenoles totales del fruto de la Punica granatum L / Development of a lab-scale technological process for total polyphenol extraction from Punica granatum L. fruit

Introducción: Punica granatum L., (Punicaceae) es una especie conocida en Cuba como granada. Algunos fitocomponentes presentes en la fruta muestran una fuerte actividad antioxidante. En la medicina tradicional esta planta es empleada en el tratamiento de infecciones parasitarias, diarreas y disentería, así como en el tratamiento de asma, catarro, fiebre, inflamaciones y otras. En años recientes, la actividad biológica de los polifenoles presentes en la fruta de esta especie, ha despertado el interés de los investigadores y la industria farmacéutica.Objetivo: establecer un proceso a escala de laboratorio que permita extraer los polifenoles totales de la fruta.Métodos: se aplicó un proceso de maceración para la extracción de los polifenoles de la fruta y se realizó la optimización de los parámetros mediante diseños experimentales. Se evaluaron las variables independientes: tiempo de extracción, relación droga-menstruo y concentración alcohólica.Resultados: las tres variables presentaron una influencia significativa sobre el proceso de extracción de polifenoles.Conclusiones: en las condiciones de trabajo establecidas, la extracción óptima es la siguiente: tiempo de extracción de 72 h, relación droga-menstruo de 1:20 y concentración alcohólica del 50 por ciento (v/v)(AU)

Introduction: Punica granatum L., (Punicaceae) is one species known in Cuba as granate. Some phytocomponents of the fruit show strong antioxidant activity. This plant is used in the traditional herb medicine to treat parasitic infections, diarrheas and dysentery, asthma, flu, fever, inflammation and other illnesses. In recent years, the biological activity of phenols present in the fruit has aroused the interest of both researchers and the drug industry. Objective: to set a lab-scale process that makes it possible to extract total phenols from the fruit. Methods: a maceration process was used to extract phenols from the fruit and the parameters were optimized through experimental designs. The independent variables were time of extraction, drug/menstruum ratio and alcohol concentration. Results: the three variables had significant influences over the process of extraction of polyphenols. Conclusions: under the set working conditions, the optimal extraction is as follows: time of extraction of 72 hours, drug/menstruum ratio of 1:20 and alcohol concentration of 50 percent(v/v)(AU)
