Background Bevacizumab is primarily aimed at pathologic angiogenesis for off-label uses such as the treatment of ocular neovascular disorders.However,as a new anti-fibrotic and anti-angiogenic agent following trabeculectomy,the safety and efficacy of bevacizumab by multiple-time and high-dose subconjunctival injection are still under study.Objective This study was to assess the safety and efficacy of bevacizumab after multiple-time and high-dose subconjunctival injections.Methods Regular trabeculectomy filtration surgery was performed on both eyes of 18 clean New Zealand White rabbits 0.1ml of bevacizumab(25g/L) was subconjunctivally injected intraoperatively and 3,5,7 days postoperatively in the left eyes of rabbits,and no any intervene in the right eyes were as normal controls.Bleb morphology was examined every 2 days and graded based on Moorefield's criteria and compared between the bevacizumab-treated eyes and normal saline(NS) eyes.The animals were sacrificed at 10,20 and 30 days after surgery respectively.The histopathological changes of the blebs were detected by hematoxylin and eosin stain to evaluate the cellular element around the bleb,and Masson stain was used to assess the degree of fibroblast proliferation.The degree of vascularity of bleb was identified by anti-vWf stain.Approval of this protocol was obtained and permitted from People's Hospital Institutional Animal Care and Use Committee of Peking University.The use of experimental animals complied with the Regulation for the Administration of Affair Concerning Experimental Animals by State Science and Technology Commission.Results Compared to the NS-treated eyes,bevacizumab-treated eyes showed the larger and more diffusely elevated blebs with the significant difference(2.48±0.22cm2 versus 1.73±0.27cm2,t=5.194,P＜0.05).The survival time of the filtration bleb in bevacizumab panel was longer in bevacizumab-treated eyes compared to control eyes,showing a significantly difference between them(21.0±1.56 days versus 12.5±1.97 days,t=3.830,P=0.005).Histological and immunohistochemical analysis confirmed that bleb and adjacent conjunctiva vascularity(A value) was significantly less in bevacizumab-treated eyes than that in control eyes at 20 days after surgery with the difference value 14320.7±4134.9(t=12.275,P＜0.05),and fibroblast deposition value was evidently diminished after bevacizumab treatment at 30 days following surgery in comparison with control eyes with the mean difference 0.27±0.03(t=15.980,P＜0.05＝.Conclusion Repeated subconjunctival injection of bevacizumab can effectively prolong the survival time of bleb in a rabbit model of trabeculectomy and limit the degree and area of vascularization in 30 days following surgery.Bevacizumab inhibit fibroblast-meditated tissue formation significantly in the later phase of vascularization after trabeculectomy.

Objective To explore the dynamic changes of soluble interleukin-2 receptor(SIL-2R) and tumor necrosis factor ?(TNF-?) levels in pediatric malignant solid tumors clinical value.Methods The levels of SIL-2R and tumor necrosis factor ?(TNF-?) were measured by ELISA in 15 cases with pediatric malignant solid tumors before and after chemotherapy.Results Before chemotherapy the levels of SIL-2R and TNF-? of every group patients were significantly higher those that of normal control group (P

Objective To investigate fracture resistance and fracture patterns of maxillary anterior endodontically treated teeth restored with two different shapes of glass fiber post systems.Methods Twenty-four human sound maxillary anterior teeth of similar size were collected,and randomly divided into 3 groups,8 teeth each.After endodontical treatment,they were given the following treatments:Group A:parallel glass fiber posts (coltene parapost fiber lux) and composite core;Group B:taper glass fiber posts (coltene parapost taper lux) and composite core; Group C (control group):intact endodontically treated teeth.Teeth in Groups A and B reserved 2 mm dentin ferrule.Then the teeth were prepared and restored with IPS e.max Press all ceramic crowns.All the teeth were embedded in acrylic resin 2 mm below the cementoenamel junction (CEJ),with the silicon impression material stimulating periodontal membrane.All the specimen were loaded under a universal testing machine,at the palatal junction of incisor third and middle third,with an angle of 135 degree to the longitudinal axis of the tooth until fracture occurred,at a cross-head speed of 1.0 mm/min.Fracture loads and patterns were recorded.Statistical analysis was performed using SPSS software.Results The mean fracture loads in the three groups were as follows:(468.8±142.5) N,(440.2±202.7) N,and (459.0±147.6) N,respectively.There was no significant difference in fracture loads among groups (P＞0.05).The incidence of unfavorable fracture in Group A was higher than Groups B and C.Conclusions There is no significant difference in fracture strength between parallel and taper fiber post groups.However,the group with parallel fiber posts demonstrates a higher risk of unfavorable fracture than the group with taper fiber posts,which indicates that taper fiber posts are more favorable to preserve the remaining tooth structure.

Objective: To observe the clinical effect of Zheng's Jin Gou Diao Yu (gold-hook-fishing) acupuncture method versus ordinary acupuncture on superficial fascia for treating neck type cervical spondylopathy in Kyrgyz. Methods:A total of 64 Kyrgyz patients conforming to the diagnostic criteria of neck type cervical spondylopathy were included. The patients were randomized into a Zheng's Jin Gou Diao Yu (gold-hook-fishing) acupuncture group and a conventional acupuncture group, with 32 cases in each group. Patients in the Zheng's Jin Gou Diao Yu (gold-hook-fishing) acupuncture group were treated with Zheng's Jin Gou Diao Yu (gold-hook-fishing) acupuncture method to stimulate the superficial fascia, the stimulation sites were primarily located at bilateral sides of the cervical vertebra as well as the trigger points in shoulder-neck region; patients in the conventional acupuncture group were punctured at the same acupoints, with twirling reducing method, and the depth of insertion was determined by the treated region. Patients in both groups received treatment every day for a succession of 5 d as a course, with a 2-day interval between 2 courses, and the whole treatment lasted for 3 courses. After 3 courses of treatment, the McGill pain questionnaire (MPQ) and neck disability index (NDI) were measured to compare the clinical effect between the two groups. Results: After treatment, scores of MPQ and NDI scale dropped when compared with those before treatment, and the differences showed statistical significance (allP<0.05); scores of MPQ and NDI in the Jin Gou Diao Yu (gold-hook-fishing) acupuncture group were substantially lower than those in the conventional acupuncture group, and the differences showed statistical significance (allP<0.05). The total effective rate was 96.9％ in the Jin Gou Diao Yu (gold-hook-fishing) acupuncture group and the cured rate was 78.1％, which were higher than 81.3％ and 40.6％ in the conventional acupuncture group, and the differences showed statistical significance (bothP<0.05). Conclusion: Zheng's Jin Gou Diao Yu (gold-hook-fishing) acupuncture method by stimulating superficial fascia to treat cervical spondylopathy in Kyrgyz can produce a better clinical effect than conventional acupuncture treatment, and is effective in improving pain and stiffness in patients, and thus is worth clinical popularization.

OBJECTIVE: To explore the application value of postmortem multi-slice spiral computed tomography (MSCT) by observing and analyzing the injury features in the traffic accident victims. METHODS: Ten traffic accident victims were scanned with whole body MSCT. The systemic autopsy was subsequently performed to compare with the results of MSCT. The advantages and disadvantages of autopsy and MSCT for obtaining the information of traffic accident injuries were then analyzed. RESULTS: MSCT could reveal 3D shape of fractures clearly and detect air accumulation in different positions of the body, which showed the obvious advantages compared with autopsy. However, the resolution of MSCT was limited compared to the detection of organ and soft tissue injuries. CONCLUSION A combination of MSCT and autopsy is the best way for determining the manner and the cause of death in traffic fatality victims.
