Objective To analyze the stroke subtypes and influencing factors in four largest economic regions of China.Methods We analyzed the investigation data of QUEST(Quality Evaluation of Stroke Care and Treatment)study conducted in 2006 which included 62 hospitals in a national scale.According to the concept of four economic regions designed by the Development Research Center of the State Council,we performed the univariate and multivariate analysis for the stroke subtypes and its related risk factors in the different economic regions.Results There were 3362(73.5％)ischemic stroke patients and 1214(26.5％)hemorrhagic stroke patients among the total 4576 first-ever stroke patients.Comparison of stroke subtypes in the four different economic regions was statistically significant(P ＜ 0.001),with a percentage of 80.8％ ischemic stroke patients in the northeastern region,78.9％ in the eastern region,68.3％ in the central region and 67.0％ in the western region.The comparisons of risk factors such as history of hypertension,diabetes,hyperlipidaemia,coronary artery event,atrial fibrillation,and overweight in the four different economic regions were also statistically significant(P ＜0.05).Conclusions The subtypes of first-ever stroke vary in the four largest economic regions with a highest proportion of ischemic stroke in the northeastern region and relatively high proportion of hemorrhagic stroke in the central and western economic regions.There are also discrepancies of stroke risk factors in the different economic regions.

Objective To explore diagnosis capability of macular ganglion cell complex (mGCC)and peripapillary retinal nerve fiber layer(pRNFL) thickness for glancoma. Methods Adult outpatients received ocular regular examinations of glaucoma in our hospital were enrolled in this study. Parameters of pRNFL and mGCC measured by Fourier optic coherence tomography(OCT) were evaluated. Results 116 subjects ( 116 eyes) included 51 (44. 0% ) normal subjects, 30(30. 2% ) early glaucoma patients and 35 (25.9%) advanced glaucoma patients. There were significantly different pRNFL and mGCC thickness among the three groups ( F = 83.022,97. 361,27. 899,79. 585,140. 686,119. 166,116. 234, 90. 855,64. 341,133.064, P ＜0. 0l ). Area under Receive Operated Curve (AROC) of all pRNFL parameters in early glaucoma except nasal ( P ＞ 0. 05 ) and mGCC parameters had significantly diagnostic capability ( Need to be corrected by authors) ( pRNFL:0. 796 ±0. 049;mGCC:0. 748 ±0. 055, P ＜0. 05). As to the whole glaucoma, AROC of pRNFL and mGCC parameters had significantly diagnostic capability ( pRNFL:0. 889 ±0. 029; mGCC: 0. 862 ±0. 034, P ＜0. 01 ). Through AROC pairwise comparisons, the diagnosticpower of almost pRNFL and mGCC parameters had no difference ( P ＞ 0. 05) except that temporal, superior pRNFL thickness were significant higher than focal loss of volume (FLV) of mGCC ( P ＜ 0. 05 ). Conclusion The measurement of pRNFL thickness might still be used as a main method on diagnosis of glaucoma and mGCC could serve as a new beneficial complement tool for detection of glaucoma.
