In recent years,PET-CT plays an important role in Hodgkin' s lymphoma (HL).It has emerged as the most accurate tool for staging,treatment monitoring,and response evaluation in HL.PET-CT has high sensitivity and specificity.It provides an opportunity to monitor the quality of response during treatment,permits separation of node from involved regions,and adds prognostic information.PET-CT has become integral to modern lymphoma management,but as a relatively new imaging technique it is still being studied and neither its full potential nor major limitations have been fully understood.The recent observations from clinical trials and clinical experiences with PET-CT in the 54th ASH annual meeting are discussed to explore its advantages and limitations.

Objective To analyze inhibitions and working memory impairments in children with different subtypes of attention deficit hyperactivity disorder (ADHD) with saccade tasks. Methods Participants,aged 10～ 13 years with ADHD-combined ( n= 19) ,ADHD-inattentive ( n= 11 ) and control subjects ( n= 18) ,were selected according to DSM-Ⅳ diagnosis,Conners teacher rating scale and parent symptom questionnaire from 1500pupils from 2 primary schools in Jinhua city by stratified cluster sampling method. Participants performed 3 different saccade tasks: 1 prosaccade and 2 antisaccades executed in a single-task and a dual-task situation. One of the antisaccade tasks was performed under the verbal secondary task condition to investigate verbal working memory.Saccades were registered by Eyelink Ⅱ Tracker. Errors and correct rate were analyzed. One-way ANOVA and repeated measures ANOVA were used to analyze the data. Results (1) Each group showed more response suppression errors on antisaccade task without load than on prosaccade task, ADHD-combined and ADHD-inattentive exhibited more errors than non-ADHD (P＜0.01) ,and errors was lower in ADHD-inattentive than in ADHD-combined ( ( 70.90 ± 15.78 ) % vs ( 84.04 ± 12.84 ) %, P ＜ 0.05 ). (2) The interactions between group and load were not significant in error rate on antisaccade tasks (P ＞ 0.05 ), but in correct rate (P ＜ 0. 05 ). The two subtypes of ADHD were affected more than non-ADHD, their correct rates tended to decrease under verbal working memory load. Conclusion An integrative view of deficits in inhibition and verbal working memory in two subtypes of ADHD is proposed, and ADHD-inattentive has a better response suppression than ADHD-combined.

Objective To observe the efficacy and safety of intravitreal injection of conbercept for wet age-related macular degeneration.Methods Retrospective clinical study.Sixty eyes of 60 cases diagnosed as wet age-related macular degeneration (AMD) definitely were intravitreally injected conbercept 0.5 mg from March 2014 to March 2016.Follow-up time was 6 months to 12 months,averaged (8.5 ± 2.4) months.Visual acuity (ETDRS charts letter),central macular thickness (CMT),leakage of choroidal neovasculaxization (CNV) and area of CNV and complications before and after the treatment were analyzed.Results Conbercept injection therapeutic times were 1-5,the average therapeutic times were 2.80 ± 0.89.At 1 month,2 months,3 months and 6 months after treatment and the last follow up,the mean letter of ETDRS charts increased (14.76 ± 5.89) letters,(19.88 ± 7.13) letters,(24.75 ± 6.74) letters,(23.94 ±6.15) letters,(22.89 ± 8.53) letters compared with pre-operation,respectively (all P ＜0.05).CMT decreased (70.19 ± 60.56) μm,(82.07 ± 57.97) μm,(95.40 ± 87.92) μm,(97.57 ± 46.68) μm,(107.46 ± 56.82) μm compared with pre-operation,respectively (all P ＜ 0.05).Before treatment,the area of CNV leakage was (12.32 ± 5.67) mm2,and at postoperative 3 months,6months the area were statistically significant different (all P ＜ 0.05).Four cases had subconjunctival flake bleeding,intraocular pressure increased slightly in 3 cases and they all recovered at 1 week after treatment.There was no serious ocular and system complication.Conclusion Intravitreal injection of conbercept for wet AMD can improve the visual acuity,decrease CMT and inhibit the CNV regression without serious complication.

Neurofibromas are benign nerve sheath tumors that arise from the nonmyelinating Schwann cells. Generally, neurofibromas can be categorized into dermal and plexiform subtypes. The former subtype is usually associated with a lone peripheral nerve in the integumentary system, while plexiform tumors are associated with many nerve bundles and can originate internally. Rarely, the plexiform tumors can undergo malignant transformation. Neurofibromas are usually found in individuals with neurofibromatosis, which is an autosomal dominant disease. On occasion, an isolated neurofibroma can transpire without being associated with neurofibromatosis. Mostly, these solitary tumors tend to occur in the gastrointestinal system, and neurofibromas of the head and neck are not uncommon, but very rarely they have been reported to occur in the temporal fossa. In this report, we describe a case of a solitary neurofibroma arising from the temporal fossa.

Otitis media with effusion (OME), a kind of inflammatory disease of the middle ear, is characterized by the retention of middle ear effusions and hearing loss. There are many factors involved in the development of OME including bacterial infection, formation of bacterial biofilms, eustachian tube dysfunction, adenoid hypertrophy, immune system disorders. Recently, some studies showed that gastroesophageal reflux has correlation with OME.
