Large artery intracranial occlusive disease is a important and common vascular lesion type.It is closcly associated with the onset and recurrence of ischemic stroke; however,at present there are many inadequacies in the study of its etiology and treatment.This article mainly reviews the understanding process of the large artery intracranial occlusive disease,present research results and problems need to be solved.

AIM: To observe the changes in contrast sensitivity (CS) between emmetropic pilots, glasses wearing, and after laser in situ keratomileuses ( LASIK) surgery pilots, provide the basis for the physical examination standard after operation.
METHODS:The CS of 13 emmetropic pilots (26 eyes), 12 glasses wearing pilots (24 eyes) and 10 with LASIK (20 eyes) , under photopic, scotopic and scotopic with glare environments at four different spatial frequencies ( 3, 6, 12 and 18cpd ) were measured and the resluts were analyzed by statistics.
RESULTS:Under photopic environments, there was no significant difference in the low spatial frequency (3cpd) among the three groups (P>0. 05). The CS of emmetropic pilots was better than that of the myopic and with LASIK, and there was significant difference (P<0. 05). There was no significant difference in CS between myopic and with LASIK (P>0. 05). Under scotopic environments, there was no significant difference in the low spatial frequency (3cpd)among the three groups (P>0. 05). The CS of emmetropic and with LASIK pilots were better than that of the myopic, and there was significant difference ( P<0.05). There was no significant difference in CS between emmetropic and with LASIK (P>0. 05). Under scotopic with glare environments, the CS of emmetropic and myopic pilots were better than that of the with LASIK, and there was significant difference (P<0. 05). There was no significant difference in CS between myopic and with LASIK (P>0. 05).
CONCLUSION: The CS after LASIK is decreased compare with emmetropic pilot, specially under scotopic with glare environments. A perfect identification standard should be set up.

Objective To observe the clinical efficacy and safety of Shuxuetong in treatment of paroxysmal atrial fibril-lation in patients with chronic pulmonary heart disease. Methods A randomized single-blinded study was performed. A to-tal of 91 patients with paroxysmal atrial fibrillation and chronic pulmonary heart disease were randomly divided into treat-ment group (n=45) and control group (n=46). The treatment group was received Shuxuetong and clopidogrel treatment for 14 days. The control group was given routine treatment plus clopidogrel 75 mg orally. The average time of cardioversion of parox-ysmal atrial fibrillation was detected within 48 hours. The cardioversion rate of paroxysmal atrial fibrillation and the total effi-ciency were detected after14 days. The serum D-Dimer was detected before and 14 days after treatment . Liver and kidney function and adverse drug reactions were also detected. Results There was no significant difference in average time of car-dioversion of paroxysmal atrial fibrillation in 48 h between two groups (h:12.62±2.32 vs 13.32±2.25,t=1.461). The cardiover-sion rates were 86.67%(39/45) and 82.22%(37/45) at 48 h and 14 d in treatment group, which were significantly higher than those of control group [69.56%(32/46) and 60.87(28/46)]. The D-Dimer at 14 d after treatment was significantly lower in treatment group [(2.05±0.34)mg/L] than before treatment[(2.61±0.27)mg/L], also than that of control group[(2.53±0.31)mg/L]. There were no abnormal liver and kidney function and no adverse reactions between two groups. Conclusion Shuxuetong can significantly prevent the recurrence of paroxysmal atrial fibrillation in patients with chronic pulmonary heart disease, and help to reduce the risk of thromboembolism. It is safe and effective.

Objective To investigate the relationship between insulin level and mild cognitive impairment(MCI) of type 2 diabetes and analyze the risk factors for MCI. Methods We collected 101 type 2 diabetes subjects who were divided into two groups:MCI and normal cognition(NC).All subjects were evaluated with cognition scores of MMSE,GDS,CMS,ADL.Insulin,glycosylated hemoglobin,blood routine test,blood pressure,ECG,brain CT were detected.Independent t-test,correlation and multiple regression analysis were performed. Results 1. The diabetic patients with MCI showed the higher levels of insulin at fasting, 2hr and 3hr after meal than did NC(P

Objective To assess the clinical application value of magnetic susceptibility-weighted imaging in cerebral vascular malformations. Methods Thirty-six patients with cerebral vascular malformations were enrolled in the study. All the patients received examination of T1WI, T2WI and SWI. SWI sequence was compared with T1WI, T2WI sequence in detecting and diagnosing cerebral vascular malformations. Results Cerebral vascular malformations were low signal in SWI sequence. Cavernous angioma, developmental venous anomalies and AVM had been found in 73,8,10 cases, respectively. The bounder of lesions was clearer, more multiple small lesions, more hair-thin pulp veins and draining veins were detected in SWI sequence. Conclusion SWI sequence has more sensitivity than T1WI and T2WI sequence in detecting the cerebral-vascular malformations. SWI sequence may become routine examination se- quence in diagnosis cerebral-vascular malformations.

Objective To investigate the influence of magnesium sulfate on C-reactive protein, white blood cells, neutrophils, gastrointestinal function and serum bilirubin levels in patients with acute cholecystitis.Methods 117 patients with acute cholecystitis were randomly divided into two groups (n=60) and control group (n=57).The control group received conventional treatment, and observation group received conventional treatment combined with magnesium sulfate.The leukocyte count and neutrophil percentage, serum total bilirubin and CRP levels, plasma vasoactive intestinal peptide ( VIP) and motilin ( MTL) levels, and disappearance time of fever, abdominal pain, gallbladder enlargement were analysed between two groups of patients.Results After treatment, the leukocyte count and neutrophil percentage of observation group were significantly lower than those before treatment (P<0.05), but there were no significantly differences in above indexes of control group; after treatment, leukocyte count and neutrophil percentage in observation group were significantly lower than those in control group (P<0.05).After treatment, serum CRP and total bilirubin levels in observation group was significantly lower than that before treatment (P<0.05), and CRP level in control group was significantly lower than that before treatment (P<0.05), while total bilirubin level in control group showed no significant change; after treatment, the above indexes in observation group were significantly lower than that in control group (P<0.05).After treatment, plasma VIP levels in both groups was significantly lower than that before treatment, respectively (P<0.05), MTL levels were significantly higher than that before treatment, respectively (P<0.05);after treatment, VIP level was lower, MTL level was higher in observation group than that in control group, respectively (P<0.05).The disappearance time of fever, abdominal pain, gallbladder enlargement in observation group were significantly shorter than that in control group, respectively ( P<0.05 ) .Conclusion The mechanism of magnesium sulfate in the treatment of acute cholecystitis may reduce leukocyte count and neutrophil percentage, serum CRP and total bilirubin, plasma VIP level and increase MTL level.
