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.

Underactive bladder (UAB) belongs to the category of "urinary retention" and "urinary incontinence" in Traditional Chinese Medicine (TCM). Its pathogenesis is based on spleen qi deficiency and kidney deficiency, while dampness heat and blood stasis are the symptoms, and the nature of the disease is basedon the deficiency in nature and excess in superficiality and simultaneous occurrence of deficiency and excess syndrome. TCM treatment of UAB is mainly based on spleen qi deficiency syndrome, kidney deficiency syndrome, water and heat syndrome, deficiency and blood stasis syndrome to be treated with oral taken of Chinese materia medica, or the use of acupuncture, moxibustion, acupoint application and other external treatments, or the combination of acupuncture and medicine, TCM combined with rehabilitation training and other comprehensive treatments. All methods can improve the urodynamic indexes of patients, relieve symptoms and improve the quality of life, with certain efficacy.

Objective To analyze basic data and outcomes in Chengdu Stroke Registry.Methods The stroke patients consecutively admitted to Department of Neurology,West China Hospital,Sichuan University since March 1,2002 were prospectively registered.The baseline demographic,risk factors,treatment,and outcome data was recorded with standardized stroke register form by trained specialists.The patients were followed up at seven days,one,three,six months and one year after onset of the stroke for death and disability.Results A total of 3123 consecutive patients were registered between March 1,2002 and August 31,2006,of which 65.5％ came from urban areas and 34.5％ from rural areas.The age was (63.05 ± 17.98) years old and male accounted for 60.3％.Ninety-seven percent (3028/3123) of patients completed CT or MRI scanning during hospitalization.A total of 1804 patients were included between March 2002 and September 2004,of which ischemic stroke accounted for 62.1％ (1120/1804),intracranial hemorrhage 28.4％ (513/1804),subarachnoid hemorrhage 4.0％ (72/1804) and TIA 5.5％ (99/1804).The median NIHSS score on admission was 8(3-15) points in patients with cerebral hemorrhage,and 5(2-10) points in patients with ischemic stroke.Compared with the patients with intracranial hemorrhage,patients with ischemic stroke more frequently had a history of diabetes (OR =2.427,95％ CI 1.811- 3.253,P=0.000),atrial fibrillation (OR=6.121,95％ CI3.535-10.60,P=0.000),coronary heart disease (OR=4.144,95％ CI 2.944-5.832,P =0.000) and TIA (OR=4.342,95％ CI 1.726-10.92,P =0.001 ),and less alcohol consumption ( OR =0.740,95％ CI 0.611-0.896,P =0.002 ).The proportion of in-hospital treatments were thrombolysis 0.9％,anti-platelet therapy 83.0％,mannitol 23.5％,neuroprotective agents (citicoline) 68.1％,and Chinese herbal medicine 89.7％.Case fatality rate was 10.7％ and 13.9％ respectively at 7 days and one month for patients with intracranial hemorrhage,3.0％ and 5.2％ respectively for ischemic stroke.Death or disability was 40.4％,40.3％ and 38.9％ in patients with intracranial hemorrhage and 37.1％,35.0％ and 33.4％ for ischemic stroke at the end of 3,6,12 months respectively.Conclusions Our stroke registry is featured with the largest sample,and the longest period of consecutively registration.It provides an important platform for clinical investigation of stroke.Our study suggested case fatality and disability is lower in this group than in other ethics.Above features should be considered in design of future clinical trials in China.

OBJECTIVETo explore the value of MSCT in the preoperative TNM staging and the longest tumor diameter measurement (RESIST standard) of gastric cancer.

METHODSClinical data of 153 consecutive patients with biopsy-confirmed gastric carcinoma who were preoperatively evaluated with enhanced MSCT scanning in our hospital from January 2012 to March 2013 were retrospectively analyzed. Consistency comparison was performed between preoperative TNM staging and the longest tumor diameter measurement and histopathological findings.

RESULTST-staging consistency of Kappa value was 0.566, and accuracy was 71.2%. N-staging consistency of Kappa value was 0.284, and accuracy was 47.7%. The Kappa value of M-staging consistency was 0.893, and accuracy was 98.7%. The overall accuracy of TNM staging consistency was 66.7% (102/153) with a Kappa value of 0.573. Effective measurement of the longest cancer diameter was carried out in 53 patients. There was no significant difference between preoperative longest tumor diameter acquired by MSCT and postoperative tumor measurement [(68.8 ± 40.6) mm vs. (64.2 ± 36.2) mm, P=0.969].

CONCLUSIONMSCT is accurate in preoperative TNM staging and longest tumor diameter measurement of gastric cancer compared with postoperative pathological examination, and can provide reliable evidence for preoperative staging and neoadjuvant therapy evaluation of gastric cancer, but it is unfavorable to evaluate the lymph node metastasis.
