Objective To investigate the therapeutic effects of retinal angiomatosis in differentclinical stages.To discuss the indication of vitrectomy for retinal hemangioblastoma. Methods TheclinicaI data of 22 cases(33 eyes)were retrospectively analyzed.The retinal hemangiomas were dividedinto 5 stages according to their degrees of development from simple angioma without vessel dilation tofeeder vessel dilation and intra-retinal exudates.local retinal detachment,massive retinal detachment andcomplication occurrence in proper order.The methods of treatment were laser photocoagulation,trans-scleral cryotherapy and vitrectomy. 13 eyes were treated with laser photocoagulation, 5 eyes withcryotherapy combined with laser and 11 eyes with vitrectomy.Tumor resection and silicone oil tamponadewas performed in 3 eyes during vitrectomy.The patients were followed up for 46 months on average.Visual acuity(VA),the condition of the hemangioma and retina was compared pre～and post-operationrespectively. Results In a11 13 eyes treated with laser phot.coagulation the hemangiomas regressed andthe retina remained attached.VA improved in 2 eyes,and remained unchanged in 11 eyes.Cryotherapycombined with laser photocoagulation was performed on 5 eyes. In this group,4 eyes'hemangiomasregressed and no new hemangiomas occurred,proliferative vitreous retinopathy and vitreous hemorrhagewas observed in 1 eye which vitrectomy was performed later.VA improved in 2 eyes,unchanged in 2 eyesand decreased in 1 eye.In the 11 eyes treated with vitreoretinal surgery,new hemangiomas was found in 1eye,exudative retinal detachment was caused by hemangiomas in 2 eyes,proliferative vitreous retinopathywas observed in 2 eyes.and the retina remained attached in 8 eyes.VA improved in 3 eyes,unimproved in3 eyes,and decreased in 5 eyes.In the 3 eyes with surgical resection of retinal hemangioma during vitrectomy,2 eyes'retina remained attached,1 eye had exudative retinal detachment and no new hemangiomas occurred.VA improved in 2 eyes and decreased in 1 eye. Conclusions Laser photocoagulation or combined with cryotherapy is effective in treating the hemangiomas in early stage.Vitreetomy is advisable for late stage of retinal angiomatosis,especially with vitreous hemorrhage,epiretinal membrane,proliferation and large scale of retinal detachment.Surgical resection of isolated large retinal hemangioblastoma may be useful for selected patients.

ObjectiveTo study the influences of fetal umbilical cord around neck on foetus、newborn infants and the choices of delivery mode during delivery.Methods220 cases of cephalic delivery pregnant women with fetus who had fetal umbilical cord around neck symptom and 220 cases of cephalic delivery pregnant women with fetus who didn't have fetal umbilical cord around neck symptom,were selected to make a contrast observation.ResultsThe foetus who had fetal umbilical cord around neck symptom had higher rate of fetal distress and neonatal asphyxia.The maternal cesarean section would be much higher,too.The rate is 18.5％,8.6％,49.6％ which were higher than the foetus who didn't have such kind of symptom,the rate is 5.4％,1.8 ％,26.4％ ( all P ＜ 0.05 ).The rate of fetal distress and neonatal asphyxia was proportional to the number of circles around neck.One circle around neck is 12.6％,1.4％ ;two circles around neck is 27.1％,17.0％ ;three and more than 3 circles around neck is 69.2％,53.8％.ConclusionWe should enhance perinatal B-mode ultrasonic examination and fetal monitoring circle around neck,pay close attention to the factor of umbilical cord around neck and select suitable delivery mode so that we can reduce the incidence of fetal distress and neonatal asphyxia.When B-mode ultrasonics displays that the number of the umbilical cord around the fetus' neck is three and more than 3 circles,the incidence of neonatal asphyxia is high and the cesarean section is the best choice under such circumstances.

Aim To evaluate the antitumor activity of ruthenium polypyridyl complexes and the underlying mechanism. Methods The right complexes 2b were filtered with highest activity and lowest toxicity by MTT assay. The change of cell cycle was detected by flow cytometry . The expression of p53 and p21 was detected by Western blot. The in vivo antitumor activity of 2b was evaluated by the assay of tumor bearing nude mice. Results 2b potentially inhibited proliferation of a variety of hepatoma cell lines, among which Hep 3B cell was the most significant ( IC50 was 12. 1 μmol · L-1 ) . The apoptosis of Hep 3 B cell was induced by 2b, as evidenced by DNA fragmentation, chromatin condensation and appearance of subG1 peak. The ac-tivities of caspase-9 and caspase-3 were activated by 2b. The phosphorylation of p53 was induced by 2b. The expression of p53 and p21 was also up-regulated by 2b. The growth of tumor of nude mice was signifi-cantly inhibited by 2b in vivo experiment. Conclusion 2b has good in vitro and vivo antitumor activities, and it can inhibite growth of Hep 3 B cells by inducing apoptosis.
