Objective: To detect the expression level of Galectin-3 in the ocular Venous Malformation (VM) tissue, and explore its associations with the occurrence and development of ocular VM. Methods: 12 fresh ocular VM tissue samples and 12 simplex great saphenous vein varices tissue samples were collected. The mRNA and protein expression levels of Galectin-3 gene were detected by RT-PCR and Western Blot. Results: The relative mRNA and protein levels of Galectin-3 in VM and control group were 5.26×10^-3±8.78×10^-4, 4.89×10^-4±5.37×10^-5 and 0.861±0.394, 0.223±0.206, respectively; Galectin-3 expressions in both mRNA and protein levels in ocular VM tissue were obviously higher than those in control group (P<0.05), and an increasing trend was accompanied with aggravating pathological changes in both degree and range of ocular VM. Conclusions Galectin-3 is highly expressed in ocular VM tissue in both mRNA and protein levels, which may be closely related to ocular VM development and prognosis, and can be used to determine the degree of local invasion of ocular VM. The pathogenesis of ocular VM may be related to Galectin-3, which can be further investigated through gene chip techniques.

Objective To evaluate the value of multi-slice spiral computed tomography angiography(MSCTA)scanning and reconstruction technology in detecting anomalous origin of coronary artery(AOCA).Methods Retrospective analysis was done in 3 856 patients who accepted MSCTA.Volume rendering(VR),multi-planar reformation(MPR),curved planar reformation(CPR)and maximum intensity projection(MIP)were used to observe the origin and course of coronary artery.Results 42 patients with AOCA were detected among 3 856 objects,and the detection rate was 1.09%.The detection rates had no statistically significant difference between male(1.17%)and female(0.98%).The rate of patients with anomalous origin of left coronary artery was 30.95%(13/42), and 9 objects(69.23%,9/13)of them had the anomalous origin of left circumflex.The rate of patients with anomalous origin of right coronary was 66.67%(28/42),and 35.71% of them(17/28)were found to have the anomalous origin of right coronary artery from the left sinus of valsalva.Conclusion MSCTA scanning and reconstruction technology is noninvasive,rapid,accurate and intuitive.

Objective RhuPAa-melittin protein with high-purity was analyzed to investigate its biologic effect on normal and ovarian cancer cells.Methods Preliminary purified rhuPAa-melittin was added in medium normal cells and SKOV3 human ovarian cancer cells cultured for 48 hours,and then were measured at 490 nm wavelength absorbance to measure the number of living cells and evalu-ate the inhibitory effect of rhuPAa-melittin on cultured cells.Results The inhibitory rate of rhuPAa-melittin at 4 μg/mL was 66.59% in SKOV3 cancer cell progression.At a concentration of 16 μg/mL, rhuPAa-melittin killed all cancer cells (P <0.05).In normal adult fibrous cells,the inhibitory rate of rhuPAa-melittin at 4 μg /mL was only 7.3%,and 12.3% inhibition rate was obtained by using rhu-PAa-melittin (8 μg/mL).Moreover,inhibition rate topped at 22.0% when used rhuPAa-melittin at 16 μg/mL.Conclusion RhuPAa-melittin has a strong anti-tumor effect on SKOV3 cancer cells.

Objective: To explore the treatment of the ocular arteriovenous malformation using urea injection combined with surgical procedures and evaluate clinical effects. Methods: 42 cases withocular arteriovenous malformation combined with fistula were retrospectively analyzed between January 2011 and December 2016. Individual treatments were formulated according to leision areas and severity. 3 cases with diffuse malformations were excluded from the study, because no surgical procedures were performed. 39 cases underwent local injection with 40% urea before resection. The urea was injected locally into vein malformation area by means ofmulti-point injection on a basis of 30 seconds, 3-6 ml for each treatment, once a day.The injection was performed for successive 7-10 days.The therapeutic effects and cosmetic result were recorded. Results: 23 cases occurred intheright ocular area and 16 cases in left.21 cases were removed radically in single operation.No recurrenceoccurredin any case with follow-ups of 3 months to 1.5 years.Cosmetic result with ocularbilateral symmetrywere satisfactory. Conclusions Combined treatment with urea injection and surgical procedure could effectively treat ocular arteriovenous malformation with arteriovenousfistula.

Objective To assess the use of bipolar radiofrequency device Habib 4X in hepatic malignant tumor resection. Methods Clinical data of 75 patients with hepatic malignant tumor undergoing hepatectomy with the use of Habib 4X in Department of Gastrointestinal Oncology, Cancer Center of Guangzhou Medical University from February 2009 to June 2013 were retrospectively analyzed. There were 55 males and 20 females with a mean age of (53±12) years old. Forty-nine cases were with primary liver cancer and 26 cases were with secondary liver cancer. The informed consents of all patients were obtained and the ethics committee approval was received. Patients received endotracheal general anesthesia. Hepatectomy was performed after tumor ablation was employed with Habib 4X device 2-3 cm away from the tumor. The intraoperative bleeding, blood transfusion, operation duration, changes of postoperative alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TB), length of postoperative hospital stay and complications were observed. Patients were followed up after being discharged from hospital and tumor recurrence and mortality were observed. Results All the 75 patients underwent hepatectomy successfully. The mean intraoperative bleeding was (318±89)ml, the rate of blood transfusion was 7%(5/75), the median of operation duration was 104 (17-191) min, the length of postoperative hospital stay was (11±4)d. ALT, AST, TB rose to a top level 1 d after operation, then went down progressively and liver function backed to normal 9 d after operation. Two cases suffered from bile ifstula and were cured after enhancing drainage. The 1-, 3-year recurrence rates were 6%(3/49), 10%(5/49) respectively in patients with primary liver cancer and were 23%(6/26), 27%(7/26) respectively in patients with secondary liver cancer. The mortality were 4%(2/49), 27%(7/26) respectively in patients with primary liver cancer and secondary liver cancer during the follow-up. Two cases with primary liver cancer died of postoperative hepatic encephalopathy and 7 cases with secondary liver cancer died of tumor widespread metastasis. Conclusions Habib 4X is safe and effective for hepatic malignant tumor resection. It may reduce the postoperative tumor recurrence rate.

Objective: To discuss the radical treatment of lymphatic vascular malformation combined intracystic hemorrhage in Children. Methods: 66 cases with lymphatic vascular malformation combined intracystic hemorrhage were retrospectively analyzed. The longest diameter of all the lesions was nearly 4 cm.All the 66 patients received surgical treatment. Arc-shaped incision was made to separate and expose the eyes from the hair trace. The lesions were separated from the frontal and temporal parts to the eyes along the dermal fat layer, and deep separation revealed orbicularis oculi muscle and levator upper eyelid muscle. Results: All the 66 cases were completely resected, and the patients were followed up for 0.5-3.0 years after the surgery. The postoperative appearance was satisfactory in 58 cases. The wound scar was healed in 8 cases, and the patients had satisfactory postoperative appearance after elective scar resection and cosmetic repair. Postoperative complications included long-term exudation of incision lymph in 6 cases. Among them, 4 cases were complicated with incision dehiscence and 2 cases were infected. Conclusions The method of complete resection of tumor as early as possible can radical cure the ocular lymphangioma with intracapsular hemorrhage, which prevent the disease from deteriorating, and meeting the aesthetic requirements of satisfactory appearance.
