简介：AbstractObjectives:Describe the h index as a bibliometric that can be utilized to objectively evaluate scholarly impact. Identify which otolaryngology subspecialties are the most scholarly. Describe if NIH funding to one’s choice of medical school, residency, or fellowship has any impact on one’s scholarly output. Determine other factors predictive of an academic otolaryngologist’s productivity.Study design:Analysis of bibliometric data of academic otolaryngologists.Methods:Active grants from the National Institutes of Health (NIH) to otolaryngology departments were ascertained via the NIH Research Portfolio Online Reporting Tools Expenditures and Reports database. Faculty listings from these departments were gleaned from departmental websites. H index was calculated using the Scopus database.Results:Forty-seven otolaryngology programs were actively receiving NIH funding. There were 838 faculty members from those departments who had a mean h index of 9.61. Otology (h index 12.50) and head and neck (h index 11.96) were significantly (P < 0.0001) more scholarly than the rest of subspecialists. H index was significantly correlative (P < 0.0001) with degree of NIH funding at a given institution. H index was not significantly higher for those that attended medical school (P < 0.18), residency (P < 0.16), and fellowship (P < 0.16) at institutions with NIH funding to otolaryngology departments.Conclusions:H index is a bibliometric that can be used to assess scholarly impact. Otology and head and neck are the most scholarly subspecialists within otolaryngology. NIH funding to an individual’s medical school, residency, or fellowship of origin is not correlative with one’s scholarly impact, but current institutional affiliation and choice of subspecialty are.

简介：摘要目的复制Feeney's自由落体模型并对实验体会进行总结。方法对14只雄性SD大鼠进行麻醉、开颅，用自制打击装置打击大鼠的皮层，模型复制后进行实验观察。结果大鼠有2只因失血过多而死亡，7只无明显表现，5只肌张力下降，运动时拖行对侧肢体行走。结论Feeney's自由落体模型可实现局部脑区不同强度的打击，动物死亡率低，但该模型的复制过程中颅骨钻容易损伤皮层，动物易因出血过多而死亡。

简介：AbstractObjective:Scoping review of published literature to establish clinical characteristics and audiologic outcomes in patients diagnosed with Susac’s Syndrome(SS) who have undergone cochlear implantation (CI).Data sources:All published studies of CI in SS and contribution of two of our own patients who have not been reported previously.Methods:A comprehensive search of MEDLINE (via PubMed) was carried out in March 2020 using the following keywords and related entry terms: Susac’s Syndrome, Cochlear Implantation. Results: Our search identified a total of five case reports of CI in SS. With the addition of our two patients reported here, we analyzed characteristics and outcomes in seven patients. Mean age at implantation was 30 years old (range 19-46), with six women and one man implanted. Mean time from onset of hearing loss to implantation was 17 months (range three months to four years). Best reported postoperative speech understanding was reported via different metrics, with six of seven patients achieving open set speech scores of 90% or better, and one subject performing at 68%. Vestibular symptoms were present preoperatively in four of seven patients (57%), with vestibular testing reported in two patients, and showing vestibulopathy in one patient. No complications were reported following cochlear implantation.Conclusion:Cochlear implantation is a viable option for hearing rehabilitation in patients with SS, with levels of attainment of open set speech comparable to other populations of CI candidates.

简介：AbstractThe main treatments for Parkinson’s disease (PD) currently include surgery, rehabilitation, and most commonly, drug therapy. However, the drugs that are currently used to treat PD provide only symptomatic relief and delayed disease progression but have no curative effect and cause many adverse reactions. When considering pathogenic factors and metabolic regulation, PD and type 2 diabetes have a high rate of comorbidity; this provides a theoretical basis for the treatment of PD with first-line antidiabetic drugs. Among these agents, metformin reduces neuronal damage in the brains of PD patients via neuroprotection and the inhibition of oxidative stress and inflammatory responses, thus providing a novel strategy for the clinical treatment of PD. Here, we present the current state of knowledge about the use of metformin to treat PD and discuss its clinical prospects.

简介：Hirschsprung’s病(简称H病)是一种肠壁神经发育障碍的先天性畸形,其发生率甚高,仅次于直肠肛门畸形,占消化道先天畸形第二位。国内称谓“先天性巨结肠症”。然其命名以Hirschsprung’s病或肠道无神经节细胞症似较恰当。
