[Objective]To evaluate the results of intraoperative autologous blood transfusion in pediatric orthopaedic operation.[Method]Intraoperative blood salvage was reinfusioned in 17 patients by Cell Saver 5.The volume of reinfusion blood and complications were recorded.[Result]Among 17 patients,an average of(171?53)ml autologous blood was transfused intraopratively.The use of Cell Saver 5 was directly responsible for a 80% reduction in the total amunts of homologous blood.Four patients has experienced transient hemoglobinuria.No other complications appeared.[Conclusion]Reinfusion of blood salvage during pediatric orthopaedic operation is safe and effective.It is able to reduce the amount of homologous blood transfusion.

Chronic active Epstein - Barr virus infection(CAEBV) is an uncommon outcome of EBV infection and may present as severe of fulminant syndrome with high- mortality. It is characterized by chronic or recurrent infectious mononucleosis-like symptoms persisting over a long time and by an unusual pattern of anti-EBV antibodies. Although it occurs in immunocompetent individuals, a number of subtle immunologic defects have been reported in patients with CAEBV. Up to now, there are still no diagnostic criteria of CAEBV in China,so the author introduce it with respect to its diagnosis,history,pathogenesis and therapeutic approaches.

Ptosis is one of the most common diseases in oculoplastics. Surgical treatment is the only way to correcting ptosis. Most of doctors paid special attention to surgical technique, rather than to some related issues of operation. Timing is crucial for ptosis surgery. Both cosmetic and function need to be considered for a success surgery, the evaluation of extraocular muscle disorder is impor- tant for surgical result and postoperative complications.

Explorations and reforms in enforcing the students’ base and cultivating their abilities were carried out in order to improve teaching quality and train specialized talents with high quality.

Objective To evaluate the sunscreen application and the level of photoprotective knowledge in both dermatologists and photosensitive patients. Methods The style, sites and amount of the sunscreen applied were examined by 0. 05 % dipyridamole cream in 39 dermatologists and 41 photosensitive patients with Wood's light. The participants were asked to fill in a questionnaire about the photoprotective knowledge. Results Frequent mistakes made by participants in this study were as follow: (1) using an inadequate amount of sunscreen; (2) putting sunscreen in the palm of the hand and rubbing the hands together before application; (3) lacking a systematic approach to sunscreen application. The median quantity of individual sites ranged from 0. 5 mg/cm2 to 1 mg/cm2 except for the forehead of the female dermatologist that had a median thickness of 1. 5 mg/cm2. The questionnaire survey showed that dermatologists also had less knowledge on sun protection even though better than photosensitive patients. Conclusions Dermatologists and photosensitive patients always fail to apply sunscreen in some prominently exposed sites and to paint the average thickness of sunscreen used far less than that of experimentally measured dose (2 mg/cm2). Continuing education and training about pho-toprotection for dermatologists should be carried out to provide better education for the patients on sun protection.

Objective To study the expression of matrix metalloproteinase(MMP)-1,-3 and-9 in sun-exposed and-unexposed skin as weil as its significance in the mechanism of skin photoaging.Methods Skin samples were resected from the exmnsor side of forearm(sun-exposed area)and flexor side of upper arm(sun-unexposed area)of 23 healthy female volunteers.The expression of MMP-1,-3 and-9 was detected by immunohistochemical staining in 46 skin samples.Immunoreactive intensity distribution index (IRIDI)was calculated to assess the expression of MMP-1,-3 and-9.Wilcoxon signed ranks test,Mann-Whitney U-test and Spearman rank correlation analysis were performed.Results MMP-1,-3 and-9 were expressed in both sun-exposed and -unexposed skin.The average IRIDI value for MMP-1,-3 and-9 was 7.70(range,3 to 12).9.22(range,6 to 12),8.30(range,6 to 12)in sun-exposed skin,and 4.26 (range,2 to 6),5.39(range,2 to 9),4.04(range,1 to 6)in sun-unexposed skin,respectively;significant difierence existed between sun.exposed and-unexposed skin in the three parameters(all P＜0.01).A significant inerease was observed in the average IRIDI value for MMP-1,-3 and-9 in sun-exposed skin vs.sun-unexposed skin in women above 50 years of age (9.17 vs 4.75,10.58 vs 6.42,8.92 vs 4.33,respectively,all P＜0.05).In women younger than 50 years,the average IRIDI value for MMP-1,-3 and-9 was 6.09(range,3 to 8),7.73(range,6 to 9),7.64(range,6 to 12)in sun-exposed skin,significantly higher than that in sun-unexposed skin[3.73(range,2 to 6),4.27(range,2 to 8),3.73(range,1 to 6),all P＜0.05].Increased IRIDI scores of MMP-1,-3 and -9 were noticed in sun-exposed skin in women above 50 years of age vs.those younger than 50 years.but there was no statistical difrerence in MMP-I or MMP-9 between the two aged groups in sun-unexposed skin(all P＞0.05).The IRIDI scores of MMP-1,MMP-3 and MMP-9 were positively correlated with age(r=0.66,0.69,0.74,all P＜0.01)in sun-exposed skin,but the IRIDI scores of MMP-1 and MMP-9 uncorrelated with age in sun-unexposed skin.Conclusions There isan elevated expression of MMP-1,-3 and.9 in sun-exposed skin VS.SUn.unexposed skin.hinting that these three MMPs play a role in the occurrence and development of photoaging,but their biological mechanism may be different.
