Objective To study the relationship of expression of central cortex glucocorticoid receptor (GR) at protein level with GR expression in the liver at protein level and with changes of serum cortisol and adrenocorticotropic hormone (ACTH) following severe closed traumatic brain injury (TBI) in mice. Methods Severe TBI was established in awake mice by using a BIM-Ⅲ biomechanical machine. At 0.5, 2, 8, 24, 48 and 72 hours after TBI, the total cytosolic GR in the cortex and liver were detected with Western blotting. Levels of serum ACTH and cortisol were measured by ELISA technique and radio-immunological assay (RIA) respectively. Results The expression of GR both in the cortex and liver were obviously down-regulated at protein levels at 2-72 hours after TBI and increased slowly eight hours after injury. The GR in the liver showed no recovery at 72 hours after injury and that in the cortex was decreased continually at 24 hours after injury. Serum ACTH and cortisol levels were increased markedly compared with control group, when there were two different peaks in the observation curve.Conclusion There is glucocorticoid resistance both in the central and peripheral tissues after severe closed TBI in the awake mice, which changes in a time-dependent manner.

OBJECTIVE:To evolve the method for effective clinical pharmacy practice. METHODS:The contents and outcome of the clinical pharmacy practice in our hospital was evaluated. RESULTS & CONCLUSION:The practice of clinical pharmacy work can help guide and promote clinical rational drug use.

Objective To understand the trend of occurrence,diagnosis,and prognosis of breast cancer in the cases treated in Peking Union Medical College Hospital(PUMCH) between 1975 and 2006.Methods A total of 1092 cases of breast cancer treated in the PUMCH from 1975 to 2006 were classified into six groups by time span and reviewed for a comparative study on the parameters of gender,age,menstruation status,tumor size,mumber of positive axillary nodes,pathologic stage,recurrence and metastasis and disease-free survival rate.Results The average age of breast cancer patient has risen from 50.90 to 53.92,while 40-49 year-old group was the largest age group of breast cancer patients,and the percentage of menopause female was the highest.Tumor size has gradually been smaller especially since 2000.The number of positive axillary nodes showed no significant change during the time periods.In all 6 groups,stage-II cases were more frequent,although the percentage of stage-0 and stage-I cases was on the rise,while the percentage of stage-III declined,and that of stage-IV remained stable.In all 6 groups,the 5-year and 10-year disease free survival rate had steadily increased.Conclusions The early diagnostic rate of breast cancer has been improving and subsequently the prognosis has improved as well.

Objective To study the management of prostate sarcoma. Methods Four cases of prostatic sarcoma were presented with review of the literature. Results Of the 4 cases,two were spindle cell sarcoma,one leiomyosarcoma and the other rhabdomyosarcoma.Combined modality therapies were used,including surgical,radiation,chemotherapy,Chinese herb medicine and immunotherapy.One case has been out of follow up and one has survived 22 months without tumor.The other two patients died within 7 and 19 months after operation. Conclusions Prostatic sarcoma is an aggressive malignancy with a bad prognosis.Individualized treatment should be formulated.

To investigate the correlation between the expression of vascular growth factor (VEGF) and its receptor KDR and angiogenesis in human colorectal cancer. VEGF and KDR were detected in 68 cases colorectal cancer by immunohistochemical SABC technique. Microvessel density was determined by immunostaining for factor Ⅷ related antigen. Results showed that the positive rate of VEGF was 55 9% (38/68) in 68 cases of colorectal carcer, and VEGF was mainly located at the cytoplasm or the membrane of the colorectal cancerous cell; KDR positive rate was 45 6% (31/68), and KDR was located in the vascular endothelial cell of colorectal cancer tissues and their related Peri Cancerous tissues but also in the cytoplasm or the membrane of the colorectal cancerous cell. VEGF was closely related to Dukes stage. Microvessel density (MVD) was significantly higher in VEGF positive tumor than in VEGF negative tumor ( P

To study time and dose related changes after gamma knife radiosurgery (GKR) in rat brain, right caudate nucleuses of rats were irradiated by OUR XGD gamma units. The maximum dosages of 20,50,75 and 160Gy were given using a 4 mm collimator. HE, Nissl, Luxol fast blue staining and immunohistochemistry were utilized to observe histological changes.Histological changes in the right caudate nucleuses such as microvessel injury, which appeared as telangiectasia, vasodilatation, vessel wall thickening and edema, and astrocyte changes, which appeared as hypertrophy and proliferation, were observed at various time points after GKR. These findings demonstrate time dependent and dosage dependent changes are found in normal cerebral tissue after GKR. These results provide an explanation of the process taking place during the latent period before delayed radiation necrosis develops.

Objective To analyze the characteristics of rhabdomyolysis (RM) caused by alcohol withdrawal syndrome (AWS). Methods The clinical data of 7 patients with RM induced by AWS were analyzed retrospectively. Results All 7 patients were male;the age was 38-63 (51.3 ± 9.8) years. All of the 7 patients showed obvious myalgia and fatigue, of whom 4 patients had limb swelling, and 3 patients had epigastric pain. Creatine kinase and myoglobin levels of 7 cases were significantly increased. One case had acute renal failure. Seven patients were improved after treatment with a large amount of fluid infusion. Conclusions For patients with AWS who have generalized withdrawal seizures and epileptic seizures, muscle cells can be damaged due to prolonged muscle contraction, which can cause RM. Changes of myoglobin, creatine kinase, renal function and liver function in patients with AWS should be monitored at clinical admissions. If RM occurs, the patients should be given early fluid therapy.
