More than 2 million strokes occur in china each year,most of which are caused by cerebrovascular stenosis. Atherosclerosis is the main reason for cerebrovascular stenosis. The effective treatment of intracranial atherosclerosis can significantly decrease the incidence of stroke. However,at present,about the treatment of intracranial atherosclerotic stenosis has not been standardized. This article reviews about the treatment methods for intracranial atherosclerotic stenosis in recent years and provides the basis for the development of standardized treatment of intracranial atherosclerotic stenosis.

PURPOSETo explore the impact of subtropical maritime monsoon climate on the frequency of ambulance use for trauma patients in a coastal region in China.
METHODStatistical analysis of data on ambulance use from the 120 Emergency Command Center in Shantou City, Guangdong Province, from January to December 2012 as well as daily meteorological data from a Shantou observatory was performed to determine how climatic factors (seasons, time, and weather) affect the frequency of ambulance use for trauma patients.
RESULTSThe daily ambulance use for trauma patients differed between spring and summer or autumn (p<0.05), between sunny and rainy days (p<0.05), and between cloudy and lightly or moderately rainy days (p<0.05).We found a linear correlation between daily maximum temperature and daily ambulance use for trauma patients (R² =0.103, p<0.05). In addition, there was significant difference in ambulance use between good and bad weather (p<0.05).
CONCLUSIONFrequency of ambulance use for trauma patients is affected by the subtropical maritime monsoon climate in the coastal region. Better weather contributes to increased daily frequency of ambulance use, which is the highest in autumn and lowest in spring.

Objective To prepare rabbit polyclonal antibody against mouse IQ and ubiquitin-like domain-containing protein (IQUB) and detect its expression in the mouse testis. Methods Full-length coding sequence of IQUB was inserted into the pET-30a(+) vector to construct pET-30a-IQUB recombinant prokaryotic plasmid. Transformation of pET-30a-IQUB plasmid into E. coli BL21 was performed, and protein expression was induced with isopropyl-beta-D-thiogalactoside (IPTG). The protein was purified through histidine-tagged fusion protein purification column, then denatured by treatment of urea with gradient concentration. New Zealand rabbits were immunized with the denatured protein to produce IQUB polyclonal antibody. Antibody titer was detected by ELISA, and Western blot analysis and immunofluorescence assay were employed to validate the effectiveness and specificity of IQUB antibody. Results pET-30a-IQUB recombinant plasmid was constructed, and protein expression of IQUB was induced successfully with IPTG. The titer of IQUB polyclonal antibody reached 1:1 000 000. The antibody specifically recognized the endogenous IQUB protein of testis in the wild-type adult mouse. IQUB was expressed in spermatogenic cells of different stages. It was localized in the acrosome and flagellum of mature sperms. Conclusion The highly specific rabbit anti-mouse IQUB polyclonal antibody is successfully prepared, which can be used for Western blot and immunofluorescence histochemistry.
