OBJECTIVE: To explore the effects of Shenfu Injection on prostacyclin, thromboxane A2 and the activities of ATPases in rats exposed to hepatic ischemia-reperfusion injury. METHODS: Twenty-four male Wistar rats weighing 200-250 g were randomly divided into two groups: Shenfu Injection (SF)-treated group (rats were treated with Shenfu Injection of 10 ml/kg through intraperitoneal injection) and untreated group (rats were administered with normal saline at the same dose and served as a control group). Hepatic ischemia was caused by Pringle's maneuver and lasted for fifteen minutes, and then one-hour or three-hour reperfusion was performed. Venous blood samples for the measurement of thromboxane B(2) (TXB(2)) and 6-keto-prostaglandin F(1 alpha)(6-keto-PGF(1 alpha)) were collected three hours after reperfusion. Liver tissue samples were collected one hour or three hours after reperfusion for the measurement of Na(+)-K(+)-ATPase and Ca(+)-Mg(+)-ATPase and for morphological studies. RESULTS: Plasma TXB(2) was lower in the SF-treated group than that in the untreated group after three-hour reperfusion (P>0.05), while 6-keto-PGF(1 alpha) was higher in the SF-treated group than that in the untreated group (P>0.05). The ratio of TXB(2) and 6-keto-PGF(1 alpha) was significantly lower in the SF-treated group than that in the untreated group (P<0.05). The activities of Na(+)-K(+)-ATPase and Ca(+)-Mg(+)-ATPase in the SF-treated group were improved obviously. A three-hour reperfusion after fifteen-minute ischemia caused important hepatic histological alterations. Marked structural abnormalities were observed in the untreated group, such as massive hepatocyte swelling, necrosis, mitochondria edema and vacuolar changes. In the SF-treated group, hepatic tissue injury was reduced significantly. CONCLUSION: Shenfu Injection protects hepatic tissue from ischemia-reperfusion injury, and such protective effects are achieved by decreasing the ratio of thromboxane A(2) and prostacyclin, and increasing the activities of Na(+)-K(+)-ATPase and Ca(+)-Mg(+)- ATPase.

Objective:To explore the impact of clinical pharmacists involved in the treatment team on the reasonable drug use rate in medical orders. Methods:Totally 782 medical records including hypertension and 1-3 kinds of hypertension associated diseases in our hospital from January 2011 to December 2011 were used as the pre-intervention group, and 1 061 ones with the same conditions from September 2012 to August 2013 were used as the post-intervention group. The patients of the two groups were divided into 8 dis-ease subgroups, clinical pharmacists performed timely intervention on the medical orders in the post-intervention group, and the rational drug use rate between the two groups was compared. Results:In hypertension, hypertension associated coronary heart disease, hyper-tension with heart failure and hypertension with diabetes subgroups,the difference in the rational drug use proportion before and after the intervention was statistically significant(P<0. 01), in hypertension with coronary heart disease and heart failure, hypertension associ-ated coronary heart disease and diabetes, hypertension with heart failure and diabetes subgroup, the difference in the rational drug use proportion before and after the intervention was statistically significant(P<0. 05), while in hypertension with coronary heart disease, heart failure and diabetes subgroups, the difference was not statistically significant(P>0. 05). After the medical records in the 8 sub-groups were aggregated, the difference in the rational drug use proportion before and after the intervention was statistically significant( P<0. 01). Conclusion:Clinical pharmacists should involve in the clinical treatment to intervene irrational drug use,which can signifi-cantly improve the medical record rationality, avoid the health risks as much as possible and ensure the medication safety and treatment effectiveness for patients.

OBJECTIVETo verify the pharmacological hypothesis of prescriptions by studying the targeted distribution of major components in stewed rhubarb in the rat model with acute pancreatitis (AP).
METHODNormal SD rats (control group, n = 5) and the AP model induced with intraperitoneal cerulein (model group, n = 5) were taken as the experimental objects. Rats of the two groups were orally administered with stewed rhubarb granules (20 g x kg(-1)). Their heart, liver, spleen, lung, kidney and pancreas were collected two hours after the administration. Such constituents as emodin, chrysophanol, physcion, rhein and aloe-emodin and their concentrations in each tissue homogenate were detected by high performance liquid chromatography-mass-mass.
RESULTAloe-emodin and physcion in stewed rhubarb whose concentrations in liver and kidney of normal rats were higher than that in pancreatic tissues, while the distribution spectrums and concentrations of the remaining components in pancreatic tissues had no significant difference with that of other organs. The concentrations of emodin, aloe-emodin, rhein and chrysophanol in stewed rhubarb in pancreatic tissues of the AP model group were higher than that in other tissues and organs, while their concentrations in pancreatic, renal and splenic tissues were notably higher than that in the normal group.
CONCLUSIONIn the conditions of AP, effective components in stewed rhubarb show a targeted distribution feature in pancreas, which provides experimental basis for the pharmacological hypothesis of prescriptions.

This study is to screen the Chinese herbal compounds which could inhibit the production of Abeta and investigate the underlying mechanism. Ten types of compounds which have potential value in the treatment of AD were selected as initial screening trial. The cell models which used could overexpress Abeta and beta-secretases or Abeta and gamma-secretases. Extracellular Abeta was determined by ELISA after the cell models treated with different concentrations of compounds (0.5-100 micromol x L(-1)), separately. Then the compounds were selected which could inhibit extracellular Abeta and their best concentration ranges were decided, too. Furthermore, the cell viability and apoptosis rate, the level of intracellular Abeta, beta and gamma-secretases were determined after the cell models treated with different concentrations of selected compounds. The results showed that 4 of the 10 compounds could reduce the level of extracellular Abeta; they were cryptotanshinone, astragalosides, gastrodin and paeoniflorin, and their best concentration ranges were 0.5-5.0, 0.5-5.0, 5.0-50, 1.0-25 micromol x L(-1), respectively. Further study indicated that the 4 selected compounds were nontoxic to the cellular models and lowering intracellular Abeta were more effective compared with extracellular; of which astragalosides and gastrodin showed dose-dependent inhibition to the activities of beta and gamma-secretases, with the maximum inhibiting rates of 78.2% and 80.3%, respectively. In conclusion, cryptotanshinone, astragalosides, gastrodin and paeoniflorin could inhibit the expression and secretion of Abeta, and the underlying inhibiting mechanism of astragalosides and gastrodin were related with the reduction of the beta and gamma-secretase activities, respectively.

Aim To explore the effect of genetic poly-morphisms of POR on the stable warfarin maintenance doses in Han Chinese patients receiving mechanical heart valve replacement. Methods The association between POR gene polymorphisms and warfarin doses of 185 Han Chinese patients were investigated through ANOVA or t test. SNPs of POR and VKORC1 were de-tected by Sequenom? DNA MassArray genotyping method. CYP2C9*3 was genotyped by polymerase chain reaction-restriction fragment length polymorphism method ( PCR-RFLP ) . Patients ’ clinical characteris-tics, INR value and daily dose were obtained from their medical records. Statistical analysis was performed by SPSS 21. 0 software. Results No mutant carriers of POR rs17148944 , POR rs56256515 and rs72553971 were found in this study. The genotype frequencies of other SNPs were in accordance with Hardy-Weinberg e-quilibrium. In the group of patients with CYP2C9*1*1 , the mutant type carriers ( T carriers ) of POR rs17685 had a significantly higher dose than CC carri-ers(3. 50 ± 1. 07) mg·d-1 vs (3. 14 ± 0. 94) mg· d-1,P =0. 03. Also, in the group of patients with CYP2 C9*1*1 and VKORC1 rs9934438 G allele carri-ers, the mutant type carriers ( T carriers ) of POR rs17685 had a significantly higher dose than CC carri-ers(4. 76 ± 0. 90) mg·d-1 vs (4. 08 ± 1. 03) mg· d-1 ,P=0. 04. No significant difference was found in different genotypes of POR rs2868177 . Conclusion These results illustrate that POR rs17685 T carrier is closely associated with a higher warfarin maintenance dose, suggesting that this SNP is useful for clinical guidance of warfarin.
