Objective To evaluate safty and effects of a single photodynamic therapy(PDT) for circumscribed choroid hemangiomas. Methods We performed a retrospective analysis of 11 eyes of 10 patients who were reated with single standard PDT. Of 10 patients, 6 males, 4 females；mean 40 .2 years old；of 11 eyes, 6 left eyes, 5 right eyes; 1 patient who both eyes wer e involved. Follow-up time varied from 1month to 14months, mean 6.2 month. Results After treatment, all tumors show various degrees of regression and subretinal fluid were absorbed completely or partly. The visual acuity of 8 eyes improved; that of 3 eyes unchanged. Conclusions PDT is effective modality for circumscribed choroid hemangiomas. (Chin J Ocul Fundus Dis,2008,24:111-113)
Objective To explore the changes in the serum Cu2+and the indexes for the liver pathology and biochemistry before and after the copper needle retained in the central veins of the rabbit ears. Methods Fortynine New Zealandrabbits were randomly divided into 5 groups: Group A (copper needles retained for 1 d), Group B (3 d), Group C (5 d), Group D (7 d), and Group E (the control group, without any copper needles retained). In each experimental group, there were 10 rabbits, and in the control group there were 9 rabbits. The rabbits in each group were arranged to have their venous blood drawn for determination of theCu2+concentration, and for observation on the changes in the liver biochemicalindexes for 5 times before and after the copper needles were retained in the central veins of the rabbit ears. At the same time, a piece of the liver tissue ineach rabbit was taken for examination of the pathological changes. All the liver samples were given the basic pathological examination; if the liver sample hadsome extraordinary pathological features, the specific pathological examinationwould be given, even using the transmission electron microscope. Results After the copper needles were retained in the central veins of the rabbit ears, the Cu2+concentration increased with the passing time. The concentrations in the groups were 1.40±0.49 μg/ml in Group A, 1.45±0.53 μg/ml in Group B, 2.01±0.40 μg/ml in Group C, 2.38±0.83 μg/ml in Group D, and 1.34±0.45 μg/mlin Group E, respectively. There was a statistically significant difference between Group D and Group E(P＜0.05). There were no significant changes in the ALT and AST levels when compared with those before the copper needles were retained(P＞0.05); however, there was a considerably positive correlation on 1st day (r=0.686, P＜0.05), 5th day (r=0.712, P＜0.05), and 7th day (r=0.768, P＜0.01) when compared with those after the copper needles were retained. The histological examination showed that aseptic inflammation subsided with the time in part of the liver. The Masson staining and the Ag staining showed that there were no obvious changes in the hepatic lobules, with no fibrosis of the liver tissues found under light microscope. Conclusion There are no obvious toxic and side effects on the rabbit liver after the copper needles are retained in its central veins.
【摘要】 目的 觀察綜合治療體表血管瘤及脈管畸形的臨床療效。 方法 2008年1月-2010年9月，收治體表血管瘤和脈管畸形患者共205例。手術治療156例，其中單純手術治療103例，合并介入治療9例，硬化劑治療44例；非手術治療49例，其中介入治療1例，硬化劑治療38例，介入合并硬化劑治療10例。術后隨訪6個月～3年。 結果 15例手術治療患者于術后6個月～2年復發，其中單純手術治療患者10例（復發率9.71%），合并介入治療患者2例（復發率22.22%），合并硬化劑治療患者3例（復發率6.82%），均再次手術治療后痊愈。9例非手術治療患者于治療后3個月～2年復發，其中8例硬化劑治療患者，1例介入合并硬化劑治療患者，均經手術治療后痊愈。余患者未見復發。 結論 以手術治療為主的綜合治療，是體表血管瘤和脈管畸形治療的良好方法。【Abstract】 Objective To observe the clinical therapeutic efficacy of comprehensive treatment on body surface hemangioma and vascular malformations. Methods Between January 2008 and September 2010, 205 pateints with surface hemangioma and vascular malformation were treated. A total of 156 patients received surgical treatment, in whom 103 received surgery alone, 9 underwent combined interventional treatment, and 44 received combined sclerotherapy. There were 49 patients underwent non-surgical treatment, including intervention in 1, sclerotherapy in 38 involving 10 had combined sclerotherapy. The patients were followed up for 6 months to 3 years. Results A total of 15 patients who had received surgical treatment recurred 6 months to 2 years after the treatment, including 10 who had been treated with surgery alone (with the recurrence rate of 9.71%), 2 combined with interventional treatment (with the recurrence rate of 22.22%), and 3 combined with sclerotherapy (with the recurrence rate of 6.82%). They were all cured after reoperation. Nine cases of non-surgical treatment recurred 3 months to 2 years after the treatment, including 8 who had received sclerotherapy, and 1 combined with interventional treatment and sclerotherapy. Patients were all cured after surgery. The other patients had no recurrence. Conclusion Applying mainly on surgical treatment, the combined therapy is a good way for body surface hemangioma and vascular malformations.
Objective To observe the influences of estradiol (E2), basic fibroblast growth factor (bFGF), and tamoxifen (TAM) on the proliferation of hemangioma vascular endothelial cell (HVEC). Methods Two strawberry hemangioma from 2 infants (case 1 and case 2) were prepared for HVEC culture. The HVEC on passage 3 were cultured in estrogenfree improved minimum essential medium (IMEM) and subjected to various treatments with 100 pg/ml 17-β-E2, 10 ng/ml bFGF, and 1×10-6 mol/L 4-OH-tamoxifen(4-OH-TAM). The experiment was divided into 5 groups: group 1(IMEM, control group), group 2(17-β-E2), group 3(bFGF), group 4(17-β-E2／bGFG) and group 5(17-β-E2／bGFG／4-OH-TAM). The cell count(CC) and DNA proliferation index (PI) were determined. Results Two cases of HVEC were successfully cultured in vitro. The HVEC showed cobblestoneslike under microscopy and factor Ⅷrelated antigen(also named as von Willebrand factor，vWF) was positive by immunochemical staining. At 9 days in case 1: CC and PI remained unchanged in the control group; CC and PI were slightly increased in group 2, being 1.4 and 1.6 times as much as those in the control group respectively (P＜0.05); CC and PI significantly increased in group 3, being2.6 and 2.3 times as much as those in the control group respectively (P＜0.01); CC and PI increased remarkably in group 4, being 3.7 and 2.9 times as much as those in thecontrol group respectively (P＜0.01); CC and PI were down to the levels of controls in group 5(P＞0.05). The results in case 2 were similar to those in case 1. Conclusion In vitro, the promoting effect of bFGF on HVEC proliferation is much ber than that of estrogen. Estrogen and bFGF enhance this proliferation in a synergistic manner, which can be inhibited by tamoxifen.
