AIM: To investigate clinical effects of local resection of eyelid tumors and pathological examination or frozen section examination as well as the stage I recovery.
METHODS: For all 92 cases 92 eyes of eyelid tumor patients who underwent local resection, reconstruction in stage Ⅰ and routine pathological examination ( 37 cases of suspected malignant tumors using frozen section examination. If it was malignant, excision by Moths surgery) . Using free palate mucosa autograft in stage I or reconstruction by Hughes surgery combined with eye flaps repaired eyelid defects.
RESULTS: The postoperative pathological diagnosis:52 cases were benign tumors, and 40 cases malignant tumors. All cases of eye flaps and hard palate mucosa grafts were survived. Followed up for more than 6mo, no tumor were recurred. The appearance and function of eyelid were satisfactory.
CONCLUSION: In this group of cases, nearly half of eyelid tumors are malignant tumors. It should be treated and operated as early as possible. For suspected malignant tumors, we use frozen section examination to confirm its properties in order to excision cleanly in stageⅠ, reducing the recurrence and metastasis. According to the eyelid defect after resection, we could do repair operation in stage Ⅰ. The inner larger defect is repaired by using hard palate mucosa transplantation or Hughes surgery. The outer layer of the eyelid defect is repaired by using eye flap glide, the free flap, the kite flap, the simple suture, etc. It should be careful when using the hard palate mucosa transplantation in the upper eyelid defect.

Objective To investigate the quantity of perforin (PF) expressed on peripheral lymphocytes of active systemic lupus erythematosus (SLE) patients and its distribution in lymphocytes subsets. The effect of glucocorticosteroid on PF expression is also explored. Methods Phenotype analysis of peripheral lymphocytes was carried out by flow cytometry. SLE patients with SLEDAI≥10 (n=16) and normal controls (n=12) were enrolled into this study. The PF expressed on the iymphocytes of SLE patients with disease flares (n=10) Was studied before and after glucocorticosteroid treatment. Results SLE patients with active disease were characterized by higher proportions of PF-positive lymphocytes and higher perforin density. PF and CD8 double positive T cell proportions was evidently increased. The proportions of PF-positive lymphocytes was correlated to SLEDAI (r=0.673). After a short period of glucocorticosteroid therapy, a reduced expression of PF was observed. Conclusion There is an increased expression of perforin in peripheral lymphocytes from SLE patients with active disease. CD8 positive T cell subsets expand significantly in those patients. In addition, the frequency of PF-positive lymphocytes is correlated with SLEDAI. Finally, glucocorticosteroid inhibits the expression of perforin.

Objective To analyze the protein expression changes of retina in diabetic mice using isobaric tags for relative and absolute quantitation (iTRAQ) approach and to study proteins of apoptosis.Methods 8 diabetic mice were chosen as the diabetic model group (DM group),8diabetic mice as the normal control group.The animals were housed in wire-bottomed cages and received normal pellet chow and tap water in a constant environment.After 10 weeks,all mice were killed,and their retina were dissected.After hematoxylin and eosin(H&E) staining,the sections of retina were examined using light microscopy.The changes of protein expression in retina were studied using iTRAQ approach.Expression of apoptosis associated proteins was analyzed using ingenuity pathway analysis (IPA).Results Compared with control group,mice retina in DM group developed looser structures,tissue edema and obvious telangiectasia under light microscopy.Using iTRAQ approach,a total of 348 differential proteins were identified.Among those proteins,16 proteins were related with apoptosis,including Ataxin-10,Protein NDRG1,mucin-4,Aquaporin-1 and annexin A4,etc.There were 8 apoptosis-related proteins in retina with up-regulation,and the other 8 proteins with down-regulation in the DM group.The relationship between these proteins were analyzed and charted by IPA.Conclusions Apoptosis may be involved in the development of diabetic retinopathy.The identification of the apoptosis-related proteins will be helpful for the further study.

Objective To explore the higher dangerous factors,the early clinical performances and its contents of neonatal pulmonary hemorrhage(NPH).Methods The clinical performances,chest radiograms and autoptical pathological materials of 66 cases of newborns who died of NPH at our neonatal department during 1993 to 2003 were reviewed and analyzed.Results The higher dangerous factors of NPH were premature delivery/low birth weight,serious diseases lead to hypoxia and severe infections.The early clinical performances of NPH were the suddenly aggravation of dyspnea and the increasing of moist sounds.The early X-ray performances were lower penetrance of lung fields extensively and well-distributly with path clouds,the intercostals space usually increased.According to the autoptical(patho)-logy,this X-ray perfomance indicated the edema of the pulmonary with small amount of hemorrhage.Conclusion The patients with the higher dangerous factors and the early clinical performances of NPH,must be diagnosed and interfered it as early as possible to reduce the mortality of NPH.
