Objective To investigate the impact of using antithrombotic drugs (anticoagulants or antiplatelet aggregation drugs)before the onset of cerebral infarction on hemorrhagic transformation after acute cerebral infarction. Methods The consecutive patients with acute cerebral infarction from Chengdu Stroke Registry Project admitted to the Department of Neurology,West China Hospital,Sichuan University from January 1,2004 to January 1,2014 were enrolled. The baseline data on admission,previous usage of anticoagulants and anti-platelet aggregation drugs,as well as CT/ MRI and other imaging data of all patients were collected. According to the results of CT/ MRI reexamined at 72 h after admission,the patients with hemorrhagic transformation were enrolled into a hemorrhagic transformation group;the patients with non-hemorrhagic transformation were enrolled into a non-hemorrhagic transformation group according to the ratio
of 1 ∶ 1. Their gender and age were matched with the hemorrhagic transformation group. The baseline data and drug used of the patients in both groups were compared. The differences of risk factors between the two groups were analyzed with multivariate Logistic regression analysis. The relationship between hemorrhagic transformation and premorbid use of antithrombotic drugs were observed. Results A total of 6 916 patients with acute cerebral infarction were enrolled,including 433 (6. 3%)hemorrhagic transformation (hemorrhagic transformation group)and 433 non-hemorrhagic transformation. (1)There were significant differences between the patients of the two groups on admission in the National Institutes of Health Stroke Scale (NIHSS)score,atrial fibrillation,previous cerebral infarction,and blood glucose levels on admission (all P < 0. 05). (2)The proportions of using anticoagulants and antiplatelet aggregation agents in the hemorrhagic transformation group were higher than those of the non-hemorrhagic transformation group (anticoagulants:14. 1% [n = 61]vs. 3. 9% [n = 17];P < 0. 01,OR,4. 01,95% CI 2. 303 -6. 993;anti-platelet aggregation drugs:14. 3% [n =62]vs. 8. 3% [n = 36];P = 0. 005,OR,1. 84,95% CI 1. 194 -2. 846). (3)The results of multivariate Logistic regression analysis showed that the use of anticoagu-lants,anti-platelet aggregation drugs,NIHSS score on admission,and random blood glucose on admission were the independent risk factors for hemorrhagic transformation (OR [95% CI]3. 302 [1. 860 -5. 862], 2. 081 [1. 281 -3. 382],1. 047 [1. 026 -1. 069],and 1. 055 [1. 011 -1. 100],respectively (all P <0. 05). Conclusion The NIHSS score and blood glucose levels on admission are the independent risk factors of hemorrhagic transformation. Using anticoagulants or anti-platelet aggregation drugs before symptom onset is independently associated with hemorrhagic transformation,however,its relationship with the long-term prognosis of acute cerebral infarction need to be further studied.

Objective:To explore the diagnosis and treatment of ketamine-associated urinary system dysfunction. Methods:Total-ly 56 cases of urinary tract symptoms with the history of ketamine abuse in recent years were retrospectively analyzed. The routine ex-amination and the examination related to the urinary system were given, and individual treatment was undertaken according to different situation. Results: The main symptom of ketamine-asscociated urinary tract dysfunction was lower urinary tract symptom (LUTS). Bladder pathologic biopsy showed different degree of inflammatory change. Imaging examination showed various degree of pathological changes, including reduced bladder capacity, thickened bladder wall, bladder contracture, ureteral stricture and hydronephrosis. Three patients had increased serum creatinine level. Conclusion: Ketamine-asscociated urinary system dysfunction is a disease with LUTS as the main clinical symptom. At the early stage, the disease is reversible with promising treatment outcome. In the progression of the disease, some patients develop irreversible histological changes in the urinary tract, which should be brought to the forefront.

OBJECTIVETo compare the clinical effects of different surgical methods for the epicanthus corrective surgery.
METHODSCanthoplasty with asymmetric Z-flap is applied in 46 cases, Y-V advancement procedure for epicanthoplasty is applied in 42 cases. The epicanthus aesthetic measurement were measured and calculated by software before and after surgery, the diameter of the iris was measured as a reference value,and the postoperative scar was assessed by VSS scale. At the same time, by measuring the lateral canthal distance, the accuracy of the measurement method can be verified.
RESULTSAll patients were satisfied with the long-term results and there were no recurrences of the epicanthal fold. The shortening ratio of the ICD is 8.36% in the group with the Z-plasty, and 5.88% in Y-V plasty. the lateral canthal distance have no diffrence before and after surgery.
CONCLUSIONSTwo surgical methods can get good results. The magnitude of correction in Z-plasty may larger than Y-V plasty, but postoperative retraction may existed in Z plasty.

Objective To investigate the influencing factors of hemorrhagic transformation in non-thrombolysis patients after acute cerebral infarction. Methods According to Chengdu Stroke Registry Project,2598 consecutive patients with acute cerebral infarction admitted to the Department of Neurology,West China Hospital within 1 week of attack from January 2010 to December 2013 were enrolled prospectively. The patients were divided into a hemorrhagic transformation group and a non-hemorrhagic transformation group according to whether they had hemorrhagic transformation or not. As for patients with hemorrhagic transformation,they were divided into a symptomatic hemorrhagic transformation (SHT)group and an asymptomatic hemorrhagic transformation (ASHT)group according to whether they had aggravation of symptom and sign. The baseline data of all patients were collected and compared between the groups. The P<0. 1 variables of the univariate analysis result were enrolled in multivariate logistic regression analysis in order to identify the independent influencing factor of hemorrhagic transformation. Results In 2598 patients,249 (9. 6%)had hemorrhagic transformation,28 of them (1. 1%)were SHT and 221 (8. 5%)were ASHT. There were significant differences in male,hypertension,dyslipidemia,atrial fibrillation,drinking and smoking ratio,blood glucose,cholesterol,low density lipoprotein cholesterol, National Institutes of Health Stroke Scale (NHISS)scores,and the trial of Org 1072 in acute stroke treatment (TOAST)classification between the HT group and the non-HT group (all P<0. 05). There were no significant difference in the related influencing factors between the SHT group and the ASHT group (all P>0. 05). The results of multivariate logistic regression analysis showed that dyslipidemia (OR,0. 588, 95%CI 0. 374-0. 924,P=0. 021)was negatively correlated with hemorrhagic transformation. Atrial fibrillation (OR,3. 188,95%CI 2. 159-4. 707,P<0. 001),blood glucose (OR,1. 081,95%CI 1. 044-1. 119,P<0.001),and NHISS score (OR,1. 305,95%CI 1. 170-1. 455,P<0. 001)were positively correlated with hemorrhagic transformation. In TOAST classification,relative to the large atherosclerotic stroke,the small artery occlusive cerebral infarction was negatively correlated with hemorrhagic transformation (OR,0. 315, 95%CI 0. 167-0. 596,P<0. 001). After removing the influencing factor of atrial fibrillation,compared with the large artery atherosclerotic stroke,cardioembolism stroke was positively correlated with hemorrhagic transformation (OR,2. 823,95%CI 1. 946-4. 095,P<0. 001). Conclusion Dyslipidemia,atrial fibrillation,blood glucose,NHISS score and TOAST classification were independently associated with hemorrhagic transformation in non-thrombolysis patients after acute cerebral infarction.
