Objective To analyze the characteristics of the common first attack of headache in patients with cerebral venous sinus thrombosis (CVST). Methods The clinical data of 51 patients who were diagnosed as CVST with MR venography (MRV)or DSA were collected retrospectively. The patients were divided into either a acute group (≤3 week,n= 32)or a chronic group (>3 weeks, n=19). Results (1)The age of onset of symptoms in these patients was 20 to 40 years,and most of them were females. Of all the first symptoms,headache ranked first,accounting for 84. 3%(43/51 );headache only accounted for 52. 9%(27/51 ),headache with other symptoms (ophthalmic symptoms, hemiplegia,and aphasia,etc. )accounted for 31. 4%(16/51 ),and other symptoms such as epilepsy, paralysis,and ophthalmic symptoms accounted for 15. 7%(8/51). (2)The proportion of headache only as the first symptom in the acute group was higher than that in the chronic group (65. 6% vs. 31. 6%,P<0. 05), and the proportion of chronic headache with other symptoms as the first symptom in the chronic group was higher than that of the acute group (P<0. 05). In addition,the proportion of the first symptom including ophthalmic manifestations in the chronic group was higher than that of the acute group (P <0.01 ). (3)Forty-three patients with headache,dull headache or distensible pain accounted for 72. 1%(31/43), thunderclap headache accounted for 11. 6%(5/43),and other kinds of headache accounted for 16. 3%(6/43),however,there were no significant differences about the types of headache between the two groups (all P>0. 05 ). Conclusion Young patients without previous history of migraine,especially women of childbearing age with sudden onset and progressive worsening headache,and the patients with idiopathic intracranial hypertension,CVST should be considered as an important possibility.

Objective To evaluate preoperative oral carbohydrate in patients receiving LC day surgery.Methods 117 patients undergoing LC day surgery in PLA General Hospital from Oct 2016 to Mar 2017 were evenly divided into three groups.Patients in group A took oral carbohydrate preoperatively,group B by iv glucose,group C by overnight fasting.The preoperative thristy and the indicators of inflammation,heart rate,blood glucose,serum insulin,insulin resistance index postoperatively were collected and compared.Results No patients suffered aspiration.There were no complications above Clavien Ⅰ level.Differences in insulin resistance index,fasting serum insulin were statistically significant between group A and group B (Z =-5.60,-4.78,P ＜ 0.05).That of insulin resistance index,fasting serum insulin and procalcitonin between group A and group C were statistically significant (Z =-2.65,-2.49,-4.02,P ＜0.05).Procalcitonin between group B and group C were statistically different (Z =-2.183,P ＜ 0.05).The preoperative thristy between group A and group B,group C were statistically different (x2 =6.47,P ＜ 0.05).Conclusions Preoperative oral carbohydrate intake is safe and feasible with the benefits of improving the quality of life in patients operated on LC day surgery.
