Objective To assess the efficacy,safety,and tolerability of Topiramate(TPM) and Sodium Valproate(SV) as prophylactic therapy for migraine.Methods Prospectively,total of 146 patients with episodic migraine were randomly divided into two groups:TPM group(74 cases) and SV group(72 cases).TPM was titrated by 25 mg per week for 2～4 weeks and the highest dose was 100 mg/d.SV was given at 200 mg twice daily during initial titration of therapy and the highest dose was 600 mg/d.The therapies lasted for 13 weeks,meanwhile the migrain frequency,days and the severity of headache were recorded in headache diaries.The severity of headache was rated on a 0～10 rating scale.Results Mean frequency of headache attack decreased from 7.01 to 1.89 times per month(P

Objective To investigate the clinicopathological features of renal cell carcinoma (RCC).Methods From December 1956 to August 2012,the clinicopathological features of RCC were studied in 705 cases and related literatures were reviewed.Results The diameter of RCC ranged from 0.6 to 18.0 cm,which the average size was 4.6 cm.The proportions of the clear cell,papillary,multilocular clear cell,chromophobe and unclassified histologic subtype were 88.9％ (627/705),4.1％ (29/705),3.3％ (23/705),1.3％ (9/705) and 2.4％ (17/705),respectively.According to the Fuhrman grading system,the proportions of grade 1,2,3,4 were 19.0％ (116/612),58.3％ (357/612),18.1％ (111/612)and 4.6％ (28/612),respectively.The rates of invasion into the renal pelvis,perirenal fat and vascular were 10.9％ (66/603),10.6％ (64/603) and 4.8％ (29/603),respectively.Of 705 cases,464 (76.6％)cases were in T1,65 (10.7％) cases in T2,73 (12.0％) cases in T3,and 4 (0.7％) cases in T4.As to the lymph node and distant metastasis,the rate was 2.8％ (17/606) and 3.5％ (21/606).The percentages of stage Ⅰ,Ⅱ,Ⅲ and Ⅳ RCC were 74.3％ (450/606),9.9％ (60/606),11.7％ (71/606) and 4.1％(25/606),respectively.The 3-,5-,10-and 15-year disease-specific survival rate for RCC was 92.8％,86.9％,76.8％ and 55.5％,respectively.To those patients with clear cell RCC,the disease-specific survival at the same time point was 92.8％,88.1％,77.4％ and 55.4％,respectively.Multivariate analysis showed that the stage was the only independent prognostic factor for RCC.Conclusions Tumor stage of RCC is the independent prognostic factor for disease-specific survival.The evaluation of renal sinus invasion and lymph node should be noted in the diagnosis of RCC.

Objective To observe the serum cortisol level in ischemic stroke patients with obstructive sleep apnea syndrome (OSAS),and discuss the influence factors and its correlation with severity of cerebral infarction.Methods Two hundred ischemic stroke patients with onset of 6 h to 3 weeks,admitted to our hospital from July 2015 to April 2017,were recruited;all patients were monitored with polysomnography.According to apnea hypopnea index (AHI),all patients were divided into ischemic stroke without OSAS group (AHI＜5/h,n=89) and ischemic stroke with OSAS group (AHI≥ 5/h,n=111).Moreover,according to AHI,patients from ischemic stroke with OSAS group were divided into three subgroups,namely,mild subgroup (5/h ≤AHI＜15/h),moderate subgroup (15/h ≤AHI＜30/h) and severe subgroup (AHI ≥30/h).According to National Institutes of Health Stroke Scale (NIHSS) scores,all subjects were divided into a group of NIHSS scores no more than 10 and a group of NIHSS scores＞10.The general clinical data,biochemical indices,early morning blood pressure,serum cortisol level and sleeping parameters were detected and compared among the groups,and the main factors affecting serum cortisol levels were identified by multivariate linear regression analysis.Results (1) The serum cortisol level in ischemic stroke with OSAS patients ([195.41±75.31] μg/L) was significantly higher than that of ischemic stroke without OSAS patients ([158.65±77.28] μg/L,P＜0.05);the serum cortisol level in ischemic stroke with mild OSAS subgroup ([227.32±75.12] μg/L) was significantly increased as compared with that in the ischemic stroke with moderate OSAS subgroup and ischemic stroke with severe OSAS subgroup ([191.27±71.50] μg/L and [175.21±75.13] μg/L,P＜0.05).(2) The serum cortisol level of group of NIHSS scores＞10 was significantly higher than that of group of NIHSS scores ≤ 10 (P＜0.05).(3)AHI,NIHSS scores,longest duration of apnea,and lowest blood oxygen saturation at night had significant effects on serum cortisol levels.Serum cortisol levels increased with AHI (β=89.984,95％CI:71.325-108.644,P=0.000) and NIHSS scores (β=0.923,95％CI:0.377-1.468,P=0.001),increased with the longest sleep apnea (β=0.804,95％CI:0.262-1.325,P=0.000),and decreased with the lowest blood oxygen saturation at night (β=-0.709,95％CI:-0.290--0.041,P=0.000).Conclusion The serum cortisol level in cerebral infarction patients with OSAS was increased,and the higher the severity of cerebral infarction and OSAS is,the higher the serum cortisol level is.
