Objective To observe the effect of Lovastatin on carotid atherosclerotic plaque(CAP),levels of blood lipid and serum C-reactive protein(CRP) in patients with cerebral infarction(CI).Methods 120 CI patients with CAP were randomly divided into Lovastatin group and control group.At the basic of low fit diet for the two groups,Lovastatin was taken with 20 mg once a day for 6 months in Lovastatin group.Then,the changes of paque score,the levels of CRP and blood-lipid were observed 8 weeks and 6 months after treatment.Results (1)6 months later,the plaque score(4.20?3.77) in the Lovastatin group was significantly lower than pro-treatment(4.77?2.31)and the control group(6.86?1.89) (all P

The pharmacokinetics and pharmacodynamics of famotidine were investigated in 10 healthy male volunteers after single intravenous administration of 20 mg. The blood drug levels were determined by a high performance liquid chromatography. The 1gC of famotidine in plasma vs time curve were found to be twcncompartment open model in healthy volunteers. The terminal half-life averaged 3.16h; the total distribution volume 99.40L; the total plasma clearance 392.12ml/min; the area under the plasma concentration curve 1057.45 h?ng/ml. A mathematic equation describing the whole course of blood drug levels in relation to inhibitory effects on intragastric acid output is as follows: E= 100?C2.60/(C2.60+14.712.60). The constant 14.71 is EC50 (ng/ml), the blood drug concentration producing 50% of maximal pharmacological effects. Prediction of pharmacodynamic effects from blood drug level and vice versa becomes possible by using the mathematic equation.

Objective: To investigate the difference between the uptake of different hydrophobe drugs into the O/W microemulsion systems and micellar solutions. Methods:Based on the phase diagram,the incorporation of 3 poorly water soluble drugs into Cremophor RH-40-alchohol-isopropyl myristate-water microemulsions and Cremophor RH-40 surfactant systems were examined. Results: There was no significant difference between miconazole nitrate and indometacin into the O/W microemulsion systems and micellar preparation.There was,however,a significant increase in the micellar solutions of ibuprofen amount than in the microemulsion systems. Conclusion:Improvement of solubility by O/W microemulsion and micellar system depends on the solubility of the drug in the dispersed oil phase and is significant only for high lipophilic drugs.

OBJECTIVE:To establish a HPLC method for determining the contents of rhein and emodin in Jianfei Jiangzhi tablets.METHODS:Stationary phase was Waters Symmetry C 18 (250mm?4.6mm;5?m),mobile phase was menthol-0.01%H 3 PO 4 (90∶10),detection wavelength440nm,flow rate1.0ml/min and column temperature30℃.RESULTS:There was good linearity in range of0.108?g～0.468?g for rhein and in range of0.180?g～0.480?g for emodin.The average recoveries of rhein and emodin were99.7%and98.6%respectively;RSD were1.93%and2.19%respectively.CONCLUSION:This method is rapid and accurate.It can be applied to effective control of the quality of Jianfei Jiangzhi tablet.

Objective: To discuss the role of clinical pharmacists played in the pharmaceutical care for osteomyelitis patients. Methods:Clinical pharmacists participated in the treatment for a special patient with osteomyelitis. Taking the disease features, medi-cal history, adverse drug reactions into account, clinical pharmacists provided consultant opinions for establishing and adjusting the ap-propriate therapeutic regimens and individualized pharmaceutical care. Results:The drug treatment regimens for the patient were safe, effective and rational. By the individualized pharmaceutical care, clinical pharmacists were able to find the problems in the drug treat-ment and implement the efficient solutions. Conclusion: Clinical pharmacists show their own advantages in individual pharmaceutical care, and play an important role in improving the rational drug use.

OBJECTIVE:To develop a HPLC method for determination of tinidazole and chlorhexidine acetate in co-tinidazole gargle.METHODS:Tinidazole and chlorhexidine acetate in co-tinidazole gargle were determined by RP-HPLC with metronidazole as the internal standard.ODS was adopted as stationary phase and acetonitrile-water(35∶65)as mobile phase.The detector was operated at UV254nm.RESULTS:The calibration curve of tinidazole was linear within the concen?tration range of(0.01～0.10)mg/ml(r=0.9999);The calibration curve of chlorhexidine acetate was linear within the con?centration range of(0.01～0.10)mg/ml(r=0.9997).The average recoveries of tinidazole and chlorhexidine were(97.06～102.02)%and(97.21～103.40)%,respectively.The within-day coefficients of variance were(0.20～1.26)%and(0.71～1.11)%,respectively.The between-days coefficients of variance were(0.50～2.06)%and(0.80～2.17)%,respective?ly.CONCLUSION:The method is suitable for determination of preparations containing tinidazole and chlorhexidine acetate.

Objective:To explore a new way of pharmaceutical service mode for disease treatment. Methods:Clinical pharmacists actively participated in the pharmaceutical care for a patient with mixed liver injury, and provided clinical pharmaceutical services through the adverse reaction analysis,etiological mechanisms exploration,therapeutic drugs selection and risk factors prevention. Re-sults:Clinical pharmacists cooperating closely with physicians helped to identify problems in time,and then the medication analysis in the fields of drug selection, dose determination, efficacy evaluation and indicators detection was performed, so that the strategies on medicine treatment could be adjusted timely as the disease progressed. With the gradual recovery of liver function, the patient dis-charged after the conditions were improved. Conclusion:By participating in pharmaceutical practice,clinical pharmacists can provide clinical pharmaceutical service,which is helpful to safety improvement and efficiency of drug administration. It is also an effective way to enhance the learning ability of pharmacists,and cultivate their clinical thinking and practice capacity.
