Objective To investigate the clinical feactures of patients with numerous dilated Virchow-Robin space in basal gangalia.Methods Eight patients with cribriform state in striatum in brain MRI at Peking Union Medical College Hospital from March 2013 to October 2013 were enrolled.The clinical data including age,gender,common vascular risk factors and clinical manifestations were analyzed.Cognitive functions,balance and gait disturbance,as well as activity of daily living were assessed.Results All of the eight patients are male,aged from 69 to 80.All the patients had a history of hyperlipidemia,while 7 of them had hypertension.The primary complaint was either gradual motor function decline or memory impairments (3/8),or dizziness (1/8).The other 4 of them were diagnosed as stroke or transient ischemic attack.Among the 8 patients,four had mild deterioration in activity of daily living function (Barthel index 65-85).Cognitive impairment was common (8/8,the Montreal Cognitive Assessment scores 19-27),while word recall was the mostly affected cognitive domain (8/8).Gait and balance dysfunction were found in three patients (3/8,Tinetti scores ≤ 24).Conclusions Man is more likely to have predisposition to cribriform state in striatum.Mild cognitive impairments and gait abnormality are common clinical manifestations of the disease.

Objective:To evaluate the systemic absorption and safety of multiple doses of topical tazarotene/betamethasone dipropionate cream in healthy subjects and patients with psoriasis.Methods:From September 2008 to April 2009, 12 healthy subjects collected from Hospital for Skin Diseases, Chinese Academy of Medical Sciences and Peking Union Medical College were randomly and equally divided into tazarotene 0.15%/betamethasone dipropionate 0.15% cream group and tazarotene 0.2%/betamethasone dipropionate 0.2% cream group; these subjects were instructed to apply 0.03 g of the test drug per day on each of the 4 body sites, including the flexor aspects of bilateral forearms, waist and back, for 7 consecutive days, and venous blood samples were obtained before, and 1, 3, 5 and 7 days after the start of drug application. From October 2010 to August 2011, 60 patients with non-cephalic psoriasis collected from the Hospital for Skin Diseases, Chinese Academy of Medical Sciences and Peking Union Medical College were randomly divided into 3 groups at a ratio of 3∶1∶1, i.e., tazarotene 0.05%/betamethasone dipropionate 0.05% cream group ( n = 36) and tazarotene 0.05% gel group ( n = 12) topically treated with a cream vehicle in the morning and the test drug at night, and betamethasone dipropionate 0.05% cream group ( n = 12) topically treated with the test drug twice a day (once in the morning and again in the evening) ; the treatment lasted 6 consecutive weeks, and venous blood samples were collected before, and 2, 4 and 6 weeks after drug application. Liquid chromatography-tandem mass spectrometry was performed to determine the concentrations of tazarotenic acid and betamethasone in plasma. During the trial, adverse events in the subjects were recorded, routine blood and urine examinations were carried out, and liver and kidney function were evaluated before and after treatment. Results:The plasma concentrations of tazarotenic acid and betamethasone in the 12 healthy subjects were below the lower limit of quantitation (0.04 μg/L) after 1-, 3-, 5- and 7-day treatment. After the consecutive treatment, tazarotenic acid and betamethasone were detected in 2 (5.56%) and 4 (11.11%) patients respectively at week 2, 4 or 6 in the tazarotene 0.05%/betamethasone dipropionate 0.05% cream group, and the highest plasma concentrations of tazarotenic acid and betamethasone were 0.112 and 0.201 μg/L respectively; in the betamethasone dipropionate 0.05% cream group, betamethasone was detected in 2 of 12 patients, and the highest plasma concentration of betamethasone was 0.112 μg/L. No test drug-related systemic adverse reactions or laboratory abnormalities were observed in any of the healthy subjects or patients.Conclusion:Multiple doses of topical tazarotene/betamethasone dipropionate cream has advantages of little systemic absorption, no long-term accumulation and good systemic safety.

Objective To evaluate the efficacy of different interventions to the extra cranial lesions in acute ischemic stroke(AIS)due to anterior tandem lesions(TL)on reperfusion.Methods As a multi-center,cross-sectional study,AIS due to anterior TL receiving mechanical thrombectomy(MT)were retrospectively collected.Interventions to the extra-cranial stenosis were recorded.Post-procedural reperfusion was assessed using the modified thrombolysis in cerebral infarction(mTICI)score.Complete revascularization was defined as mTICI 3 and good revascularization was defined as mTICI 2b/3.The relationship between different extra-cranial intervention regi-mens and rate of re-vascularization was compared.Results Totally 117 patients were included with 92.3% reaching good recanalization and 63.2% reaching complete re-canalization.There was no significant difference in good re-canalization rates among various extra-cranial intervention regimens.The rate of complete re-canalization was significantly higher in patients receiving endovascular therapy(P＜0.05)and there was significant difference among various endovascular treatment regimens(P＜0.01):acute balloon angioplasty only group presented the highest rate of complete re-canalization(100.0% ),followed by acute stenting only group(80% ),acute stenting+balloon angioplasty group(73.7% )and conservative treatment group(54.3% ).Conclusions Endovascular inter-vention to extra-cranial stenosis contributes to complete re-canalization in AIS due to anterior TL receiving MT,and acute balloon angioplasty seems to be quite effective than acute stenting.
