Objective:To explore the participation of clinical pharmacists in drug treatment. Methods:Clinical pharmacists car-ried out pharmaceutical ward round, and understood the medication history of one breast cancer patient with postoperative pneumonia. They thought the induction possibility of trastuzumab likely to be non infectious pulmonary infiltration. Combined with the drug instruc-tions, relevant literatures and case report, they put forward suggestions for the medication, and participated in the formulation of drug therapy. Results:The suggestions of clinical pharmacists were adopted, and on the second day of methylprednisolone sodium succinate treatment, the symptoms of the patient were improved, and the results of the imaging examination also tended to be improved without recurrence. Conclusion:The participation of clinical pharmacists in the formulation of clinical medication has important significance for improving the level of clinical treatment.

AIM: The aim of the present study was to clarify the mechanism of intracellular signal transduction in Ang Ⅱ- induced proliferation of vascular smooth muscular cells (VSMC) by observing the effect of c- Src on Ang Ⅱ- mediated mitogen- activated protein kinase (MAPK) activation and c- Fos protein expression in cultured VSMC of rats. METHODS: Cultured aortic VSMCs from SD rats were transfected with anti-sense c-Src oligodeoxynucleotides (ODNs) wrapt with lipofectin to inhibit c- Src activity and protein production. Untransfected VSMCs were used as control. We observed the role of Ang Ⅱ stimulation in MAPK activation and c- Fos protein expression. c- Src kinase activity was measured by protein immunoprecipitation and kinase autophosphorylation. The phosphorylation rate of the substrate myelin basic protein (MBP) was employed to assess MAPK activity.Western immunoblot was used to detect protein expression of c- Src and c-Fos. RESULTS: c-Src protein expression in VSMC transfected with different concentrations of anti- sense ODNs significantly decreased in a negative dose- effect manner. c- Src kinase activity was also markedly inhibited. Following the stimulation of Ang Ⅱ on transfected VSMCs with anti-sense ODNs, the increase rate of c- Src activity was 8.7% of that in control, the activity of MAPK was 1.6% compared with control and c- Fos protein expression was as 30.0% as that of control. CONCLUSION: Ang Ⅱ induces c- Src activation. MAPK activation and c - Fos protein expression by Ang Ⅱ is dependent on c- Src activation. These findings indicate that c- Src is an important signal factor in Ang Ⅱ-induced VSMC proliferation.

BACKGROUND:The creep performance of bone tissues during exercise is achieved through the microstrain,and the holosteous torsion can completely retiect the biomechanicel charactedstics of bone tissues.OBJECTIVE:To determine the creep characteristics of rabbit tibia under the torsion load following exercise.DESIGN,TIME AND SETTING:A parallel controlled animal observational experiment was performed at the Laboratory of Biomechanics in Orthopedic Hospital of Sichuan Province between May 2005 and July 2007.MATERIALS:A total of 32 Japanese white rabbits,irrespective of genders,aged 6 months,were divided into exercise group(n=24)and control group(n=8).METHODS:Exercise group animals were placed in cage to receive electrical stimulus.0.1-0.2seconds once every 20 seconds.Following the stimulation,the animals ran and jumped for several paces along with the cage and made a tum,15 minutes once,three times per day,totally 45 minutes,at the interval of 15 minutes.The exercise was carried out five days per week for 4successive weeks.The control group was fed as exercise group.but received no exercise.MAIN OUTCOME MEASURES:After 4 week exercise.the tibias were griped by the torsion clamping apparatus,the creep characterizes of anterior,posterior,medial and lateral sides of tibia under 0.52 N·m torsion load within 500 seconds were determined by strain gauge technique.RESULTS:Under torsion load,the creeps were present obviously in the rabbit tibia,reached the creep curve inflection point at 2seconds,and then gradually appeared.After 4 weeks,the creeps of tibias at anterior and posterior side in the exercise group were less than control group;in the control group,the anterior side of tibia was remarkably greater than the medial side.After exercise.the creep was the smallest in anterior side,which was less than the lateral side(P＜0.05).CONCLUSlON:The creep characteristics of tibia are anisotropic,the deformation at the anterior and posterior sides is greater than that at the medial and lateral sides.Exercisecan alter the creep charactedstice of rabbit tibia and reduces the creep at the anterior and posterior sides.
