To explore the effect of different processing methods and conditions of coumarin and volatile compounds in Angelica Dahuricae Radix and their change regularity, in order to optimize and establish appropriate drying methods and conditions. After being cleaned, fresh Angelica Dahuricae Radix herbs were baked, sun-dried, shade-dried, sun-dried after sulfur-fumigation, dried by quick-lime embedding, freeze-dried, microwave-dried. Finally, 24 groups of samples were obtained after being mashed and passing through the 60-mesh screen. The HPLC-PDA method was adopted to simultaneously determine the content of coumarin compounds. The GC-MS method was used to determine the content of volatile compounds. The principal component analysis (PCA) was made on the standardized analysis results for the 24 groups of samples processed with different drying methods. According to the PCA results, the comprehensive scores of coumarin and volatile compounds in Angelica Dahuricae Radix herbs processed with different methods in the order from high to low were that unpeeled and dried by quicklime embedding > unpeeled and dried with hot-air at 100 degrees C > unpeeled and dried with hot-air at 40 degrees C > peeled and infrared-dried > peeled and dried with hot-air at 60 degrees C > peeled and dried with hot-air at 40 degrees C > peeled and sun-dried > peeled and dried with hot-air at 60 degrees C > peeled and dried with hot-air at 100 degrees C > peeled and microwave-dried > peeled and dried with hot-air at 80 degrees C > unpeeled and sun-dried > unpeeled and dried with sulfur-fumigation > peeled and dried with sulfur-fumigation > unpeeled and dried with hot-air at 120 degrees C > unpeeled and freeze-dried > unpeeled and infrared-dried > peeled and dried with hot-air at 120 degrees C > peeled and freeze-dried > peeled and dried by quicklime embedding > unpeeled and dried with hot-air at 80 degrees C > peeled and shade-dried > unpeeled and shade-dried > unpeeled and microwave-dried. According to the findings, different drying processing methods have certain impacts on the content coumarin and volatile compounds in Angelica Dahuricae Radix herbs. The traditional method of drying by quicklime embedding is recommended as the optimum origin processing method of Angelica Dahuricae Radix, which is followed by the method for being peeled and dried with hot-air at 100 degrees C.

Simvastatin is a hypolipidemic drug that inhibits hydroxymethylglutaryl coenzyme A (HMGCoA) reductase to control elevated cholesterol,or hypercholesterolemia.Previous studies have shown that simvastatin may attenuate inflammation in ischemia-reperfusion injury and sepsis.Herein,we hypothesized that simvastatin may prevent rats from lipopolysaccharide (LPS)-induced septic shock.In our study,rats were divided into a saline group,an LPS group and an LPS plus simvastatin group.Male Sprague-Dawley (SD) rats were pretreated with simvastatin (1 mg/kg) for 30 min before the addition of LPS (8 mg/kg),with variations in left ventricular pressure recorded throughout.Ninety min after LPS injection,whole blood was collected from the inferior vena cava,and neutrophils were separated from the whole blood using separating medium.The neutrophils were then lysed for Western blotting to detect the levels of urokinase-type plasminogen activator (uPA) and plasminogen activator inhibitor-1 (PAI-1).In addition,mesentery microcirculations of inlet diameter,outlet diameter and blood flow rate were measured in all three groups.The results indicated that simvastatin significantly promoted heart systolic function and increased the level ofuPA while simultaneously inhibited the expression of PAI-1 as compared with LPS group.Moreover,simvastatin reversed the LPS-induced inhibition of mesentery microcirculation.Taken together,it was suggested that simvastatin can effectively protect the rats from LPS-induced septic shock.

The incompatibility of traditional Chinese medicines is related to the clinical medication safety, so has attracted wide attentions from the public. With the deepening of studies on the incompatibility of traditional Chinese medicines represented by 18 incompatible herbs, the incompatibility of theory traditional Chinese medicines has raised to new heights. From the origin of incompatibility theory of traditional Chinese medicines, relationship of herbs, harms of incompatible herbs and principle of prevention to toxic effects of specific incompatible medicines, the innovation and development of the traditional Chinese medicine incompatibility theory was explored. Structurally, the incompatibility of traditional Chinese medicines refers to the opposition of two herbs based on seven emotions and clinical experience. The combination of incompatible herbs may lead to human harms, especially latent harm and inefficacy of intervention medicines. The avoidance of the combination of incompatible herbs and the consideration of both symptoms and drug efficacy are the basic method to prevent adverse reactions. The recent studies have revealed five characteristics of incompatible herbs. Toxicity potentiation, toxication, efficacy reduction and inefficacy are the four manifestations of the incompatible relations. The material changes can reflect the effects of toxicity potentiation and toxication of opposite herbs. The accumulation of toxicity and metabolic changes are the basis for latent harms. The antagonistic effect of main efficacies and the coexistence of positive and negative effects are the distinctive part of the incompatibility. The connotation of incompatible herbs plays an important role in the innovation of the traditional Chinese medicine incompatibility theory.
