Methods A total of 58 patients suffered from pancreatic cancer pain,who were treated in the department of pain medicine of the First Hospital of China Medical University from October 2013 to December 2014,were recruited for the study. The patients were divided into two groups according to the willing of the patients and their families,group A(32 cases)was treated with Visceral Nerve Plexus ethanol Neurolysis,while group B(26 cas?es)was treated with oral opioid drugs. The analgesic effect,changes in the amount of opioid drugs,changes in the PSQI scores and the improvement of quality of life were evaluated before treatment and 1 day(T1),15 days(T15),30 days(T30),60 days(T60)after treatment. Record the adverse reactions in the course of treatment. Results All the patients of group A successfully received visceral nerve plexus ethanol neurolysis,the VAS scores,Karnofsky scores,and PSQI scores of all the observed time points(after the operation)were statistically different compared to those before treatment and group B. Statistically difference was also observed in quality of life between two groups(P<0.05). The amount of opioid drugs of group B was statistically increased than that of group A(P<0.01).The most common side effects in Group A were postural hypotension(6 cases),diar?rhea(2 cases),and intercostal neuralgia,while nausea(20 cases),constipation(11 cases)and dizziness(8 cases)were seen in the Group B. Con?clusion Visceral nerve plexus ethanol neurolysis through post?curs of diaphragm approach by the guide of CT is effective and safe for the patients with pancreatic cancer pain,and the complications were totally acceptable.

Background Retinopathy of prematurity is mainly due to retinal neovascularization.Objective This laboratory work was to evaluate the efficacy of different dosage of avastin for inhibiting retinal neovascularization.Methods Ninety 7-day-old clean C57BL/J6 mice were randomized into six groups as follows:air control group,hyperxia control group,hyperxia BSS group and avastin groups.C57BL/J6 mice in air control group were raised in regular air environments.The fifty mice were fed under the environment with 75% ±2% oxygen for 5 days to establish the retinal neovascularization models.The 1.25,2.50 and 5.00 g/L avastin (0.5 μl) were injected inteavtreally in forty-five mice models as low,moderate and high dosage avastin groups respectively,and 0.5 μl BSS was used at the same way in fifteen models as hyperxia BSS group.The mice were sacrificed in the 17-day-old age using excessive anesthesia method and the retina sections were prepared for the calculation of the numbers of vascular endothelial cell nuclei broken retinal inner membrane after hemotoxylin and eosin staining.The expression of CD34 in the retina was detected by immunochemistry.The morphology and distribution of retinal neovascular vessel in various groups were observed using retinal flat.The use of the animals followed the Regulations for the Administration of Affairs Concerning Experimental Animals by State Science and Technology Commission.Results The numbers of cell nuclei broken the inner limiting membrane was significant increased in the hyperxia group compared with the air control group( P<0.01 ),and those in difference doses of avastin were considerably reduced in comparison with hyperxia BSS group (P<0.01) and hyperxia group (P<0.01 ).The decrease of numbers of cell nuclei broken the inner limiting membrane was obvious in low dose of high dose of avastin compared with low dose of avastin (P<0.05 ).CD34 was positively expressed in retina internal membrane of hyperxia group.Retinal flat revealed the regular distribution and normal structure of retinal vessels in air control group and avastin groups.However,retinal and vitreous cavity neovascularization,leakage and enlarged non-perfusion regions in the perimeter of the retina were seen in hyperxia group and hyperxia BSS group. Conclusions Intravitreal injection of avastin can arrest retinal angiogenesis in oxygen-induced retinal neovascularization models in a dose-dependent manner.
