Objective To study the characteristics of Chinese ischemic stroke subclassification (CISS) in relation with migration to different climatic zones in autumn and winter.Methods Ninety-six subjects who travelled from northeast China,northwest China and north China to Hainan Province from September 2012 to February 2017 and were admitted to our hospital due to cerebral infarction occurred within 3 weeks after they arrived at Hainan were included in this study.Their demographic data,risk factors for cerebrovascular disease,laboratory blood test and imaging parameters were recorded.The patients were classified according to their medical history,auxiliary examination findings and CISS.The recorded data were statistically analyzed.Results CISS showed that penetrating artery disease,large artery atherosclerosis,cardiogenic stroke,and undetermined etiology accounted for 50.0％,38.5％,4.2％,7.3％ respectively.Hypertension (70.8 ％) and abnormal glucose metabolism (61.5％) were the major risk factors for cerebral in farction.Conclusion The incidence of penetrating artery disease is the highest,followed by that of large artery atherosclerosis in cerebral infarction patients.Alert to cerebral infarction should thus be stressed for those with hypertension and abnormal glucose metabolism who are going to travel in autumn and winter.

Objective To systematically assess whether cilostazol can delay the progression or decrease the carotid intima-media thickness (clMT).Methods Papers on the effect of cilostazol on cIMT in randomized controlled trials and cohort studies were retrieved from a number of foreign and domestic databases.The data were analyzed by Review Manager 5.3.Results Six randomized controlled trials and two cohort studies were included in this study.A total of 1107 patients were divided into cilostazol therapy group (n=533) and control group (n=574).Meta-analysis showed that cilostazol therapy for 6 months,12 months,≥24 months could reduce the maximum cIMT with a mean difference of-0.04 mm (95％CI:-0.05--0.03,P=0.000),a mean difference of -0.04 mm (95％CI:-0.05--0.03,P=0.000) and a mean difference of-0.08 mm (95％CI:-0.11-0.05,P =0.000) respectively.Conclusion Cilostazol therapy for 6 months,12 months,24 months or more than 24 months can reduce the maximum cIMT,which is needed to be confirmed by studies with a large sample of clinical data.

Objective:The paper aims at developing a method of defining and visualizing the scope of the basic medical insurance pharmacy service, and provides a new way of thinking for the designated pharmacy planning. Methods:Collecting the basic data and information on administrative divisions in the planning area taking equity and efficiency as the guidance, using ArcGIS and its function modules to define and visualize the scope of the medical in-surance pharmacy service. The procedure of issue focus, method improvement, data simulation, expert consultation, methodology perfecting were followed to define and visualize the scope. Results:Forming a whole set of operative pro-cedures of defining and visualizing the scope of the medical insurance pharmacy service based on medical resources allocation standard, and the operation commands and procedures in ArcGIS were clarified. Conclusion:Operating ac-cording to the appropriate method steps, the following can be achieved:(1) The adjacent scope of medical insurance pharmacy service are adjacent to each other but do not overlap or cross;(2) Spatial relations can be clearly and ef-fectively expressed;(3) The shape is flat and regular;(4) The data collected at different times can be comparable in space, providing good prerequisites for medical insurance designated pharmacy planning.

C-fos is a transcription factor that plays an important role in cell proliferation, differentiation and tumor formation. The aim of this study was to clone the goat c-fos gene, clarify its biological characteristics, and further reveal its regulatory role in the differentiation of goat subcutaneous adipocytes. We cloned the c-fos gene from subcutaneous adipose tissue of Jianzhou big-eared goats by reverse transcription-polymerase chain reaction (RT-PCR) and analyzed its biological characteristics. Using real-time quantitative PCR (qPCR), we detected the expression of c-fos gene in the heart, liver, spleen, lung, kidney, subcutaneous fat, longissimus dorsi and subcutaneous adipocytes of goat upon induced differentiation for 0 h to 120 h. The goat overexpression vector pEGFP-c-fos was constructed and transfected into the subcutaneous preadipocytes for induced differentiation. The morphological changes of lipid droplet accumulation were observed by oil red O staining and bodipy staining. Furthermore, qPCR was used to test the relative mRNA level of the c-fos overexpression on adipogenic differentiation marker genes. The results showed that the cloned goat c-fos gene was 1 477 bp in length, in which the coding sequence was 1 143 bp, encoding a protein of 380 amino acids. Protein structure analysis showed that goat FOS protein has a basic leucine zipper structure, and subcellular localization prediction suggested that it was mainly distributed in the nucleus. The relative expression level of c-fos was higher in the subcutaneous adipose tissue of goats (P < 0.05), and the expression level of c-fos was significantly increased upon induced differentiation of subcutaneous preadipocyte for 48 h (P < 0.01). Overexpression of c-fos significantly inhibited the lipid droplets formation in goat subcutaneous adipocytes, significantly decreased the relative expression levels of the AP2 and C/EBPβ lipogenic marker genes (P < 0.01). Moreover, AP2 and C/EBPβ promoter are predicted to have multiple binding sites. In conclusion, the results indicated that c-fos gene was a negative regulatory factor of subcutaneous adipocyte differentiation in goats, and it might regulate the expression of AP2 and C/EBPβ gene expression.
