Objective To investigate the relationship between perioperative allogeneic blood transfusion and postoperative infection. Methods The records of 213 consecutive patients undergoing elective radical resection of colorectal cancer at the first Affiliated Hospital of Zhongshan University from January 1st, 2001 to December 31st, 2001 were reviewed. The association of allogeneic blood transfusion with postoperative infection was analyzed by logistic regression. Correction for multiple analysis were made to eliminate the effects of confounding factors. Results Among the patients who received transfusion the incidence of postoperative infection was higher than that among those who received no allogeneic blood ( P

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

To control the quality of Maca, the quality standard was established in this study. According to the methods recorded in the Appendix of Chinese Pharmacopoeia (2010 Edition), the water, extract, total ash, acid insoluble substance, and heavy metals inspections in Lepidium meyenii were carried out. N-benzyl-9Z, 12Z-octadecadienamide in L. meyenii was identified by TLC, and it was determined by HPLC. The results showed that the N-benzyl-9Z, 12Z-octadecadienamide identification of TLC was a strong mark and specificity. In content determination experiment, the linearity of N-benzyl-9Z, 12Z-octadecadienamide was in the range of 0.01-2 microg (r = 0.9998), and the average recovery (n=9) was 99.27% (RSD 2.0%). The methods were simple, accurate, with good reproducibility. It is suitable for quality control L. meyenii.

AIM:To study the effect of posterior sub - Tenon's capsule injection of triamcinolone acetonide ( TA ) in treatment of patients with diffuse diabetic macular edema ( DME) before panretinal photocoagulation ( PRP) .
METHODS:Retrospective analysis of the clinical data of 96 cases (96 eyes) with DME treated in our hospital from October 2008 to May 2012, and the patients were divided into the study group and control group, each group with 48 cases ( 48 eyes ) , the control group were only treated with PRP, and for the study group, TA was injected one week before PRP. At 6mo after treatment, best-corrected visual acuity ( BCVA) and retinal thickness changes of two groups were compared, the changes of intraocular pressure in two groups was analyzed.
RESULTS:After treatment, two groups were followed up for 6mo, compared with before treatment, the expression of BCVA in control group was reduced, and rise in the study group, with significant difference between the two groups (P<0. 05), and during the follow-up period, IOP change was in the normal range for the two groups, with no the difference (P>0. 05), the study group had foveal thickness reduction of 9. 6μm, the control group was increased by 31. 9μm, with significant difference (P<0. 05), parafoveal thickness in the study group decreased 5μm, significantly increased 22. 1μm in the study group, centre concave surrounding thickness increased 0. 4μm in study group and 19. 4μm for the control group, with no significant difference (P>0. 05).CONCLUSION:TA injection in patients with diffuse DME before PRP is safe and effective, and it is superior to simple PRP therapy, and it can be applied in primary hospital.
