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 evaluate the impact osteolytic cytokines of expression induced by micrometer-diameter wear particles(Ti-6Al-4V and UHMWPE).Methods Filtration air was subcutaneously injected into rats'back 6 times(3 mL q?d).After a week,wear particles suspension(group A: Ti-6Al-4V,group B: UHMWPE) or physiological saline(group C) was injected into air pouch tissues.After 14 days,pouch tissues were obtained from killed rats,and were weighted,wax embedded and stained with hematoxylin and eosin, observed under microscope.AKP of serium with Automated Biochemical Analyzer,IL-6 and TNF-? expression with immunohistochemical method,and mRNA expression of extracellular matrix metalloproteinase inducer(EMMPRIN) with real-time Polymerase Chain Reaction method were detected.Results Air pouch tissues were similar to limiting membrane of periprothesis tissue in the cases of aseptic loosening.As to pouch tissue weight,there was a significant increase in group B than in group C(P

Objective To evaluate the efficacy and safety of imiquimod 5% cream applied with different treatment courses for preventing the recurrence of condyloma acuminatum lesions.Methods A randomized,controlled clinical trial was conducted.Patients with condyloma acuminatum were divided into 3 groups (Group A,B and C).Group A was treated with CO2 laser only.Group B was given topical im- iquimod 5% cream three times a week over 4 weeks after laser treatment of visible warts.Group C was giv- en topical imiquimod 5% cream three times a week over 8 weeks after laser treatment of visible warts.All patients were followed up for 6 months.Results A total of 90 patients with anogenital warts were enrolled in,and finished the study.The recurrence rates of the Group A,B,and C were 64.29%,50%,21.88%,re- spectively,in 6 months of follow-up.The recurrence rate was statistically lower in Group C than in Group A and B (P=0.0033),and in Group C than in Group B (P=0.0457).Adverse reactions occurred in 73.33% and 84.38% of patients in Group B and C,respectively,which included erythema,itching,pain, burning,erosion,ulceration and flu-like symptoms.There was no significant difference of the frequencies of adverse reactions between Group B and C (P＞0.05).Conclusion The recurrence rate of anogenital warts declines significantly in patients treated with imiquimod 5% cream for 8 weeks,but not in the 4 weeks group,after laser therapy.The frequencies of adverse reactions are not significantly different in both groups.

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 The scale lists applied in the diagnosis and treatment of heat stroke generally draw on other specialty scales, and there is no specific scoring system on heat stroke verified by large-scale clinical trials.The paper compared common acute physiology and chronic health evaluationⅡ( APACHEⅡ) , dissolved inorganic carbon score( DIC score) , multiple organ dysfunction score( MOD score) for the prognostic evaluation of heat stroke patients, the sum of three scores and the sum of the percentages of three scores to the score sum on prognostic evaluation of heat stroke patients in order to find a scoring method with higher clinical value. Methods APACHEⅡ, MOD score, DIC score, the sum of three scores and the sum of three scores were applied on 43 patients with heat stroke admitted in our neurological intensive care unit ( NICU) or in intensive care unit ( ICU) .The analysis of the area under the receiver operating characteristic ( ROC) curve( AUC) analysis was made among five scores. Results The weighted sum of three scores has the largest AUC ( 0.896 ) in predicting the death of HS patients according to AUC.The optimal MOD score was 5.5 in predicting the death of HS with a sensitivity of 72.7%and a specifici-ty of 99.69%.The optimal DIC score was 1.5 in predicting the death of HS with a sensitivity of 100%and a specificity of 56.2%.The op-timal score of the sum of the percentages of three scores to the score sum was 0.727 in predicting the death of HS with a sensitivity of 72.7%and a specificity of 100%. Conclusion All the five scores can predict the prognosis of patients with heat stroke.However, due to the deficiency in the prognosis value, a more specific scoring system needs to be developed.
