Objective To study the effect of Danshen on the pharmacokinetics of Rosuvastatin in rats. Methods Parallel control method was applied in this study. Twelve male rats weighing (230 ± 15) g were evenly randomized into two groups: rosuvastatin (80 mg/kg) group and Rosuvastatin plus Danshen (400 mg/kg) group. Blood samples (0. 3 ml each) were collected from the orbital vein at 0. 5, 1, 1. 5, 3, 5, 8, 10, 12 and 24 h after drug administration. LC-MS was used to determine the plasma concentrations of Rosuvastatin. The pharmacokinetic parameters of the two groups were compared and statistical analysis was performed using SPSS12. 0 software. Results When combined with Danshen, the Cmax, AUC0-t, and AUCo-∞ of Rosuvastatin were increased by 60. 81%, 88. 00% and 82. 92%,and T1/2 and CLz/F were reduced by 33. 21% and 21. 51%, respectively. Conclusion Danshen can affect the pharmacokinetic properties of Rosuvastatin in rats.

Objective To make up an exercise prescription based on traditional Chinese medical training (EP-TCMT) for patients with stable chronic obstructive pulmonary disease (COPD).Methods Eighty-five pa- tients with stable COPD were randomly divided into a control group (CG group),a traditional Chinese medicine group ( TC group) and an exercise prescription group ( EP group).The patients in the TC and EP groups were giv- en intensive training for 8 weeks.Their 6 rain walk distance (6MWD) and Borg scale scores were assessed before and after the treatment.Results The 6MWD in the TC group increased from 337.68?59.18 m to 386.14?76.71 m,while those in the EP group improved from 348.00?55.94 m to 425.17?53.22 m.The Borg scale scores in the TC group decreased from 3.14?1.94 to 2.32?1.25,while those in the EP group declined from 3.45?1.84 to 1.72?0.70.Conclusion Making up EP-TCMTs is feasible.Additional treatment was found to improve exercise tolerance and decrease dyspnea in COPD patients.Exercise therapy based on traditional Chinese methods is easy and safe.

In our previous work, we found that trivalent dimethylarsinous acid (DMA(III)) have high affinity binding to cysteine residue 13 of rat hemoglobin. However, it is still unknown why arsenic intermediate metabolite DMA(III) has high binding affinity for Cysl3 but not for other cysteine residues 93, 140, 111 and 125. In order to better understand the molecular mechanism of DMA(III) with rat hemoglobin, we have done current study. So, SD rats were divided into control and arsenic-treated groups randomly. Arsenic species in lysate of red blood cells were analyzed by HPLC-ICP-MS, and then determined by a hybrid quadrupole TOF MS. In addition, trivalent DMA(III) binds to different cysteine residues in rat hemoglobin alpha and beta chains were also simulated by Molecular Docking. Only Cys13 in alpha chain is able to bind to DMA(III) from the experiment results. Cys13 of alpha chain in rat hemoglobin is a specific binding site for DMA(III), and we found that amino acids compose pockets structure and surround Cys13 (but not other cysteine residues), make DMA(III) much easy to bind cysteine 13. Taken together, the DMA(III) specific binding to Cys13 is related to spatial structure of Cys13.

OBJECTIVETo investigate the protective effect of Danxuetong injection (DXT, a combination of Danshen and Xueshuantong injections) against testicular ischemia-reperfusion injury following testis torsion/detorsion in rats.

METHODSThirty-two 4-week-old healthy male SD rats were randomly divided into four groups of equal number: sham operation, normal saline, single DXT injection, and successive DXT injection. The rat models of testicular ischemia-reperfusion injury were established by 2-hour 720-degree torsion/detorsion of the unilateral testis. At 6 weeks after modeling, the rats were killed and their testes were harvested for measure- ment of testicular coefficients, sperm counts, sperm motility, and the levels of total anti-oxidative capacity (T-AOC) , superoxide dismutase (SOD) , nitric oxide synthase (NOS) , and malondialdehyde ( MDA) in the testis tissue.

RESULTSCompared with the rats of the normal saline group, those of the single DXT injection and successive DXT injection groups showed significant increases in the testicular coefficient (0.11 ± 0.03 vs 0.35 ± 0.04 and 0.40 ± 0.06, P < 0.05), sperm count ([0.46 ± 0.10] vs [1.44 ± 0.50] and [3.00 ± 1.28] x10(9)/ml, P < 0.05), sperm motility ([13.63 ± 14.04] vs [39.63 ± 5.04] and [76.31 ± 3.67]%, P < 0.05), the activity of SOD (72.76 ± 5.58 vs 116.25 ± 8.83 and 133.20 ± 13.84, P < 0.05), and the level of T-AOC (5.58 ± 1.07 vs 13.34 ± 5.81 and 19.21 ± 5.69, P < 0.05), but a remarkable decrease in the content of MDA (42.38 ± 8.94 vs 20.94 ± 5.65 and 15.02 ± 1.03, P < 0. 05) in the injured testes.

CONCLUSIONDXT can effectively rid the testis tissue of oxygen free radicals, improve sperm count and motility by antioxidation, and protect the testis tissue of prepubertal rats against testicular ischemia-reperfusion injury after testis torsion/detorsion. It also has a protective effect on the contralateral testis, and successive injection has a better effect than single injection of DXT.

Plants in Ainsliaea genus, belongs to Compositae family, are traditional Chinese medicine and widely used in folk. These plants contain various types of chemical components, and main components are sesquiterpene lactone and its glycosides. In addition, there are triterpenoids, flavonoids, steroids, phenolic acid, long chain fatty acid and volatile oils. Recently, much attention has been payed to varlous research of A. fragrans. This paper reviewed and summarized the chemical components to provide the theoretical basis for the use of Ainsliaea.

Objective To explore the influencing mechanism of Zhengan Xifeng Decoction on blood pressure and gastrointestinal motility in SHR. Methods After 15 WKY and 90 SHR rats were were randomly divided into normal control group, model group, Benner Pury group, amlodipine group, Zhengan Xifeng Decoction high, middle, and low dose groups. The normal control group and model group were fed with distilled water daily. Rats in treatment group were administered with corresponding drugs daily. Blood pressure, gastric residual and intestinal propulsive ratio of rats was detected after eight-week intervention. Results Compared with the blank control group, systolic pressure, diastolic pressure, and mean arterial pressure were significantly higher than WKY rats of same age (P<0.05). Compared with the model group, the systolic pressure, diastolic pressure, and mean arterial pressure of treatment groups were significantly reduced (P<0.05). Compared with the blank control group, gastric residual rate of rats in the model group significantly decreased (P<0.05). Compared with the model group, the gastric residual rate in Zhengan Xifeng high dose group increased significantly, and intestinal propulsive ratio significantly increased (P<0.05), without statistical significance in the other treatment groups. Conclusion Zhengan Xifeng Decoction can reduce blood pressure in SHR, and regulate gastrointestinal motility.
