AIM:To explore the histopathological classification and incidence of orbital space-occupying lesions in children in order to provide references for the diagnosis of orbital space-occupying lesions in children.
METHODS:A total of 290 paediatric patients with orbital space - occupying lesions diagnosed by pathological examinations at the Second Hospital of Tianjin Medical University from January 1998 to December 2012 were retrospectively reviewed.
RESULTS:In 290 paediatric patients with orbital space-occupying lesions, venous hemangioma was the most common (58 cases,20. 0%), the other commons were as follows: hemangio lymphangioma, dermid cyst, neurofibroma, optic nerve glioma, rhabdomyo sarcoma and so on. Capillary hemangioma, venous hemangioma, optic nerve glioma had the predominant age incidence. On the other hand, optic nerve glioma, venous hemangioma, rhabdomyosarcoma had the predominant sex incidence.
CONCLUSION: The majority of paediatric patients with orbital space - occupying lesions are congenital and embryonic lesions, the most common of which is venous hemangioma. Some lesions had the predominant age and sex incidence.

Apoptosis is a cell suicide process with a major role in development and homeostasis in bodies. Dysregulation of apoptosis, involved with inhibitors of apoptosis (IAPs), contributes a variety of disease states including cancer. The recent progress of members of IAPs family and the anticancer strategy against IAPs is reviewed in this paper.

Objective To explore the role of hemoglobin (Hb) level in mortality and morbidity of chronic kidney disease (CKD)patients,aiming to give some evidence for therapy of anemia.Methods Randomized,clinical trials (RCTs) were identified by searching Medline,Embase and the Cochrane library.All the analyses were performed using the Revman software available free from the Cochrane collaboration.Results Twenty-three trials involving 10 204 patients were identified.Overall,the high Hb target was associated with increased risk of all-cause mortality (RR=1.10,95％ CI 1.00 to 1.21),hypertension (RR=1.40,95％ CI 1.12 to 1.75),stroke and hospitalization (RR=1.07,95％ CI 1.00 to 1.14) compared with low Hb target (P＜0.05).No significant difference was found in the risks of non-fatal mycardial infarction (RR=1.13,95％ CI 0.79 to 1.62) and renal replacement therapy (RR =1.00,95％ CI 0.85 to 1.18).Conclusions Targeting low Hb target is beneficial to CKD patients based on reduced risk of hypertension,hospitalization,stroke and all-cause mortality.However,no significant difference is found in non-fatal mycardial infarction and renal replacement therapy.

Objective To investigate the effect of sevoflurane preconditioning on the expression of Toll-like receptor 4(TLR4) during myocardial ischemia reperfusion(IR) in rats.Methods Thirty male SD rats weighing 250-300 g were randomly divided into 3 groups (n=10 each):sham operation group (S group) , IR group and sevoflurane preconditioning group(SP group).Myocardial ischemia was produced by temporary ligation of anterior descending branch of left coronary artery for 30 min followed by 2 h reperfusion. In SP group, the animals inhaled 2.5% sevoflurane for 30 min followed by 15 min washout before ischemia. The rats were sacrificed at 2 h of reperfusion, hearts removed and myocardial tissues obtained for microscopic examination.The expression of TLR4, NF-κB and TNF-α was detected using Western blot. Results The expression of TLR4, NF-κB and TNF-α was significantly up-regulated in IR and SP groups compared with group S (P＜0.05).The expression of TLR4, NF-κB and TNF-α was significantly down-regulated in group SP compared with group IR (P＜0.05).The myocardial injury was attenuated in group SP.Conclusion Sevoflurane preconditioning can attenuate myocardial IR injury by inhibiting the up-regulation of TLR4 expression and reducing the inflammatory response.

BACKGROUND: Some studies have demonstrated that the degradation of extracellular matrix (ECM), which matrix metalloproteinases (MMPs) participates in, plays a key step in the corneal neovascularization (CNV). Tissue factor pathway inhibitor 2 (TFPI-2), a new type serine proteinase inhibitor found recently, can effectively inhibit the activity of MMPs. Whether TFPI-2 gene transfection can influence CNV is unclear.OBJECTIVE: To investigate the effect of TFPI-2 gene transfection on CNV.DESIGN: Randomized controlled experiment.SETTING: Laboratory for Department of Surgery, Wuhan Union Hospital; Central Laboratory, the Affiliated Third Hospital of Sun Yat-sen University.MATERIALS: This study was carried out in the laboratory for Department of Surgery of Wuhan Union Hospital and State Central Laboratory of the Third Hospital Affiliated to Sun Yat-sen University between June 2004 and March 2006. Sixty healthy purebred adult New Zealand rabbits of either gender, weighing 2.5 to 3.0 kg, were involved. Preoperatively, no obvious anterior segment ocular lesion was found by slit-lamp examination. pBos-Cite-neo/TFPl-2 was kindly gifted by Dr. Zhong Ren (Department of Hematology, Union Hospital). Peroxydase blocking agent, nonimmune goat serum,mouse anti-human MMP-1, 2 and 3 monoclonal antibodies, biotin labeled goat-anti-mouse IgG second antibody (Santa cruz Company) were used in this study.METHODS: Experimental intervention: Experimental rabbit models of CNV were created in each group by silver nitrate cautery. Then, the rabbit models were randomized into 3 groups and 20 rabbits for each group. Different reagents were subconjunctivally injected via many points in each group: saline in the group Ⅰ, empty vector in the group Ⅱ, plasmid encoding TFPI-2 in the group Ⅲ. Experimental evaluation: CNV growth was observed under the slit-lamp biomicroscope.The expression of TFPI-2 in each rabbit model was detected by reverse transcription-polymerase chain reaction (RT-PCR) method 2 weeks after modeling; the expression of MMPs in corneal tissue was detected by immunohistochemical method at 3,5,7,9 and 14 days after modeling.TFPI-2 gene expression was significantly higher in the group Ⅲ than in the group Ⅱ and group Ⅰ (P ＜ 0.01); The MMP-1, 2, 3 expressions in the corneal tissue were significantly lower in the group Ⅲ than in the group Ⅱ and group Ⅰ,respectively, especially MMP-1, 3.

?AlM: To observe the changes of corneal topography and astigmatism et al with various duration of closing eyes and sleep;and study the impact of closing eye and sleep causing physiological hypoxia on corneal topography.
? METHODS: Sixteen volunteers were selected ( 32 eyes), 22-33 (26. 19 ± 3. 95) years old, without refractive errors and other eye diseases, as well as never wearing corneal contact lens, including 10 male eyes and 22 female eyes. The main parameters received corneal simulation K value, corneal astigmatism, corneal irregular measure ( ClM ) and the shape factor ( SF ) by Zeiss corneal topographer. They were measured before and after closed eyes 10, 20, 30, 60, 120min; before sleep and after over 6h sleep, they were detected immediately as soon as they opened eyes after 10, 20, 60, 120min.
? RESULTS: During closing eyes, there were no statistical significance on the changes of corneal topography, corneal astigmatism, and SF. After opening eyes and over 6h sleep, there were no statistical significance on the changes of corneal topography, corneal astigmatism, ClM, and SF.
?CONCLUSlON:Closing eyes and sleep don’t injure the cornea substantially, so corneal topography and corneal astigmatism don’t mainly change.

Objective:To investigate the current situation of surrogate in China,analyze the reasons,and then provide effective suggestions and countermeasures.Methods:A questionnaire survey was conducted among medical staff and patients in an institution with assisted reproductive technology (ART),combining literature review and sociological research methods such as data maps,to explore and analyze the surrogacy.Results:The number of institutions with ART increased rapidly and its regulation became difficult.More surrogate network was observed in first-tier cities as well as the eastern and southeastern coastal provinces.That respondents agreeing with surrogacy was quite serious in some provinces.The reasons of surrogate were patients' needs,social concepts,weak government supervision,and so on.Conclusions:It should improve the laws of ART,explore long-term supervision mechanism,strengthen the management of internet,shield the information about surrogate,enhance medical ethics education for ART staff,and guide the infertility patients to establish the correct ethical concepts.
