Objective:To explore the expression of MIP-1? during healing of skin incised wound and the applicability of time-dependent expressions of MIP-1? to determination of wound age. Methods:An incised wound was made in the dorsal skin of mouse. Immunohistochemical and image-analysis techniques were employed in vital skin wounds 1h~14d after incision and postmortem incision 0.5~6h after death, and the non-incised mouse skin was used as contro1.Results:In the vital skin incisions,expression of MIP-1? began at 6h after incision,which increased subsequently,and peaked at 3d.The quantity of MIP-1?expression decreased and minimized in the specimens aged 14 days. In the non-wounded groups and postmortem incision groups MIP-1? was only detected as weak expression in the epidermic cells,sweat gland cells and endothelial cells. Conclusion:The time-dependent expression of MIP-1?during healing of skin incised wound may be used as a useful reference marker.

Objective The purpose of this study was to investigate the relationship of p185 and p53 protein overexpression with pathological types and recurrence.Antibodies against p185 and p53 proteins were used to measure expression of these proteins in the nuclei or cell membrane of cells from sections of the giant cell tumor of bone GCT.It showed that 11 out of 52 tumors overexpressed p185 protein and 14 out of 52 tumors had abnormally high levels of p53 protein,4 cases had abnormally high levels of both p185 and p53 proteins,positive expression rates of p185 and p53 in cases with recurrence and cases without reccarrence were 46 2%,20 5% and 38 5%,15 4% respectively.However,there was no association between p185 and p53-positive cases and pathological degree.There was significant correlation between the expression of p185 and p53 protein in the giant cell tumor of bone and recurrence.(? 2=6 125,P=0 047).However,there was no statitically significance between the expression of p185 and p53 protein in the giant cell tumor of bone and pathological types.So that,we consider that the clinical significance for p185,p53 overexpression in GCT to be researched further.

Objective To observe the effect of enhanced extracorporeal counterpulsation (EECP) on intraocular pressure (IOP). Methods 25 patients were measured their IOP bilaterally with Schoitz tonometer before and after EECP. Results The IOP decreased in both left and right eyes after EECP (P<0.01). Conclusion EECP can reduce intraocular pressure.

Objective:To establish the content determination method of the main alkaloids protopine and tetrahydropalmatine in Corydalis decumbens (Thunb.) Pers. Methods: HPLC was used to determinate the main alkaloids protopine and tetrahydropalmatine in Corydalis decumbene (Thunb.) Pers. Supelcosil LC 18 DB Column was used, mobile phase consisted of Methol NaAc/HAc(75∶25 pH5.0) and detection wavelength at UV 285 nm. Results: Linearity of this method was good with the average recoveries, 98.04% and 99.63%. Conclusion: This method is accurate, reliable with good separability and reproducibility, it can be applied as standard for the control of Corydalis decumbens (Thunb.) Pers.

Objective To assess the value of ultrasound guided percutanuous automatic biopsy of mediastinal tumors.Method Forty-six consecutive biopsies were performed on forty-six patients suffered from mediastinal tumor included 14 thymomas,12 lymphomas,9 metastasis carcinomas,5 mediastinal lung carcinomas,3 teratomas,2 neuroblastomas,1 granulosa cell tumor.Under US guidance,a 18-guage core needle with automatic biopsy device was used.Specimen was fixed with 10% formaldehyde solution.Results The procedure of puncture was successful in all patients.The positive rate histologically was 89%(41/46).No complication (such as hemorrhage,pneumothorax and dyspnoea) was happened.Conclusion We consider that the ultrasound-guided percutaneous needle biopsy is a safe and reliable method for the histological diagnosis of mediastinal tumors.

Objective To investigate the efficacy of percutaneous automatic renal biopsy guided by ultrasound with two approaches. Methods One hundred and fifty patients who were suspected with diffuse renal disease were divided into two groups randomly: group A (n=74) and group B (n=76). In both groups A and B, an 18G cut needle with automatic biopsy gun was inserted the inferior pole of right kidney from proximal and distal end of transducer, respectively. After accomplishment, the times of puncture, length of sample, number of glomeruli and complications were recorded were recorded. And the number of glomeruli per centimeter was calculated. Results The differentiation of diffuse renal disease was assured by the specimens obtained by biopsy in all the patients. The puncture times in group A was less than those in group B (P0.05), and the number of glomeruli per centimeter in group A was more than that in group B (P
