Objective To analyze statistically the international impact of the Chinese Sci-tech TOP journals published from 2011 to 2015, so as to provide solid evidences for the foundation for the exploration of the regulatory institutional mechanism and devel -opment of China′s outstanding Sci-tech journals .Methods Based on the data from the Annual Report International Citation of Chinese Academic Journals from 2012 to 2016, the international total citation (TC), international impact factor (IF) and international clout in-dex ( CI) of TOP 5%and TOP 5%-10%journals of in Chinese Sci-tech field in 2011-2015 years were statistically analyzed .Results The international impact of TOP journals in Chinese Sci-tech field from 2011 to 2015 increased year by year , the average TC of TOP 5%journals increased by over 10%annually, and that of TOP 5%-10%journals increased by over 20%annually.The average IF all increased by over 20%annually, and the number of SCI and English journals also increased year by year .The international influence of some non-SCI journals , including Chinese non-SCI journals , surpassed that of certain SCI journals by a larger margin , which deserved further study and analysis .Conclusion To further expand influence of academic journals , the editorial boards of related journals should devote more efforts to attract high quality papers so as to build high caliber publishing platforms .In addition , bilingual publication might be a better form for global dissemination of journals , and the rapid rise and development of language translation software and intelligent translation might contribute to the solution of the problem .

A 26-year-old male presented with a 6-day history of paroxysmal headache which was worsen with nausea and vomiting for 1 day. Head CT on admission revealed left chronic subdural hematoma with midline shift. An emergency Burr hole drainage for hematoma was performed. Headache recurred 6 days later. MRI of the brain revealed a diffuse thickening and a gadolinium-enhancement of the falx, cranial dura mater and tentorium cerebelli on the left side with pia mater involved. Lumber puncture showed increased intracranial pressure and elevated IgG level in cerebrospinal fluid. Histological examination of the biopsy specimen showed thickened, fibrotic dura with a sterile chronic inflammation. According to pathological examination, idiopathic hypertrophic cranial pachymeningitis was considered as the final diagnosis. Symptoms were improved with steroid pulse therapy.
