  Xiaofeng SHEN;Yuwei LI;Guoqiang LIANG;

  [Objectives] To study the anti-inflammatory effect of Wumen Zhike Gancao Decoction(ZKGC) on rats with lumbar disc herniation(LDH) associated with lipid metabolic disorder. [Methods] A rat model of LDH was established by implantation of the autologous nucleus pulposus from the coccygeal vertebra of each rat tail, and histopathology, immunohistochemistry and biochemistry assays were employed to evaluate the treatment effects of ZKGC. In addition, the metabolic characteristics of LDH and ZKGC treatment were investigated with a liquid-chromatography with time-of-flight mass spectrometer(LC/Q-TOF-MS)-based metabolomics study. Nucleus pulpous tissues from rat models were collected and analyzed by metabolomics. [Results] By metabolism network analysis, lipid metabolism was up-regulated in LDH rat models and the treatment with ZKGC significantly reversed the abnormal up-regulated lipid metabolism. Meanwhile, the treatment of ZKGC also regulated the markers of neuron autophagy and inflammatory response in serum. [Conclusions] These results indicated that a complex mechanism, including abnormal lipid metabolism, associates with the progress of LDH, and multiple pathways might be involved in ZKGC's therapeutic effects on LDH.

  Jinfeng CHEN;Li JING;Cong GAO;Renming XIE;Zhongyi LEI;Chaofeng LIU;Hong FAN;

  [Objectives] To explore the effects of Danqu capsules(the prescription of Lei Zhongyi, the master of traditional Chinese medicine for the syndrome of intermingling of phlegm and static blood of coronary heart disease) on arterial blood pressure, heart rate and myocardial tension time index in rats. [Methods] A total of 50 SD rats, weighing(300±20) g, were randomly and evenly divided into Danqu capsule observation groups(low, middle and high-dose groups) and control groups(saline group and captopril group). Under anesthesia, the rats in each group were administered with 0.6, 1.2 and 2.4 g/kg of Danqu capsule suspension, 1 mL/100 g of saline and 10 mg/kg of captopril, respectively through duodena, and their systolic blood pressure, diastolic blood pressure, mean arterial pressure, pulse pressure difference and heart rate were measured and recorded by RM6240 multi-channel physiological signal acquisition and processing system before administration, 10, 20, 30, 40, 50, 60, 90 and 120 min after the administration, respectively, and the myocardial tension time index was calculated. [Results] Compared with the saline group, the systolic, diastolic and mean pressure reduced 10, 20, 30, 40, 50, 60, 90 and 120 min after the administration, and the pulse pressure difference did not change significantly in the Danqu capsule groups(low, middle and high-dose groups), and the heart rate slowed down and the myocardial tension time index reduced in the high-dose Danqu capsule group. Compared with the captopril group, the Danqu capsule groups showed similar blood pressure-reducing effect. [Conclusions]Danqu capsules have obvious effect of lowering blood pressure and myocardial tension time index. High-dose Danqu capsules has the effect of slowing down the heart rate. The blood pressure-lowering effect of Danqu capsules shows a dose-dependent manner. Clinically, they can be used in patients with coronary heart diseases and hypertension, suggesting that they should be used with caution in patients with hypotension.

• Protective Effect of GRK2 and Effect of Sanguis Draconis Flavones on Focal Cerebral Ischemia-Reperfusion Injury in Rats

  Rui LI;Huiyu JIA;Deyun JIA;Min SI;Dewu JIA;

  [Objectives] To explore the protective effect of Sanguis Draconis flavones(SDF) on rat focal cerebral ischemia-reperfusion injury(CIRI) models established by middle cerebral artery occlusion(MCAO). [Methods] A total of 60 healthy adult male Sprague-Dawley rats were selected. They were evenly and randomly divided into sham group, model group, edaravone group(12 mg/kg) and SDF group(360 mg/kg), and administered intragastrically and intraperitoneally. The middle cerebral artery of each rat was blocked by suture-occluded method to establish a CIRI model. After ischemia for 2 h and reperfusion for 48 h, the pathological injury on the ischemic side was observed by HE staining; the neuron and myelin sheath structure was observed by transmission electron microscopy; the expression of G protein-coupled receptor kinase 2(GRK2) was preserved by immunohistochemistry; and the transfer of GRK2 was detected by western-blot. [Results] After 48 h of CIRI, the nuclei of the penumbral cortical neurons shrank, the chromatin was unevenly distributed, the nuclear membrane was dissolved and the mitochondria in the cytoplasm were swollen and vacuolated. The myelin layer was disordered. With this change, the distribution of GRK2 subcellular cells in the penumbra of the injured lateral cortex transferred from the cytoplasm to the membrane. SDF can effectively restore neuronal and myelin sheath structural damage and reduce the functional(membrane coupling) expression of GRK2. [Conclusions] GRK2 may be an effective target for SDF to protect the impaired blood-brain barrier(BBB) in CIRI.

  Qingsong GE;Yi GAO;Hang WANG;Jiangping FANG;

  [Objectives] To study the differences in fruit traits of different populations of Paeonia ludlowii,and to provide basic data for the identification,protection and utilization of germplasm resources of P. ludlowii.[Methods] Nine fruit traits of three different populations of P. ludlowii in Tibet were tested and analyzed.[Results]The mean values of 9 fruit traits of P. ludlowiiwere different in different populations;the coefficients of variation of different traits of different populations were also different; there were morphological differences of different sizes among individuals in each population; there were significant differences in 8 traits (pod length,pod width,pod thickness,pod weight,seeds per pod,seed length,seed width,and seed weight) among different populations. Among the 9 traits of the three P. ludlowii populations,the variability of the five traits was higher in the fruit pods,the variation degree of five traits including pod weight,pod thickness,seeds per pod,and seed weight was higher. It is of great significance for the screening and preservation of the germplasm resources of P. ludlowii. According to the principal component analysis (PCA),the seed weight,seed width,and seed length,i. e. the seed traits,were the main factors causing differences in fruit traits among populations. There was a certain correlation between different traits of P. ludlowii. Among the 36 Pearsonrelated combinations of 9 fruit traits,11 combinations had extremely significant correlations,and 8 combinations had significant correlations,indicating that there was a certain correlation between fruit traits in the growth and development. Through cluster analysis,three populations of P. ludlowii can be divided into two categories. The BV population was a category,which is characterized by long pods,long seeds,wide seeds,thick seeds and large seed weight. Therefore,the BV population is suitable material for breeding excellent varieties.[Conclusions]This study provides basic data for the identification,protection and utilization of germplasm resources of P. ludlowii.
