Objective The primary objective was to determine whether Danshen agents can improve functional outcome without causing undue harm in patients with acute ischaemic stroke. Secondary objectives were to assess the effect of Danshen agents on impairment and on the quality of life. Methods Searches were performed in the Cochrane Stroke Group Specialized Trial Register, Trials Register of the Cochrane Complementary Medicine Field, Chinese Stroke Trials Register and data from the pharmaceutical company. In addition, we searched the electronic bibliographic databases: Cochrane Controlled Trials Register (CENTRAL/CCTR) Issue 1, 2002, MEDLINE (1996 to 2002), EMBASE (1980 to 2002), China Biological Medicine Database (1978 to 2002). We handsearched ten Chinese journals potentially related to our question. Two reviewers selected studies, assessed quality of studies, extracted data independently. The primary outcomes of death or dependency at the end of long term follow-up(at least three months) and adverse events were assessed. Secondary outcome measures included: measures of neurological deficit at the end of treatment, death from all causes within the first two weeks of treatment and during the whole follow-up period and quality of life. Results Eight potentially eligible trials were identified, of which three trials (304 patients) were included. Two trials were excluded and three trials were waiting for assessment. Number of death and dependency at the end of long term follow-up (at least three months) were not reported in the three included trials. Only one trial reported the adverse events. Three trials measured neurological deficit at the end of treatment. Danshen agents were associated with a significant improvement in neurological deficit (RR 1.07, 95%CI 1.01 to 1.14). There was no death and during the whole treatment period and there was no assessment on quality of life. Conlusions There were too few patients and outcome events to draw reliable conclusions from the present data. The methodological quality of all included studies was poor. Further high quality randomised controlled trials should be performed.
Objective To investigate the correlation between the uric acid to high-density lipoprotein cholesterol ratio (UHR) and the presence of atherosclerotic stenosis in both intracranial and extracranial arteries among patients who have experienced cerebral infarction. Methods Patients with cerebral infarction admitted to the Department of Neurology of Sichuan Provincial People’s Hospital between January 2021 and June 2024 were retrospective selected. According to the digital subtraction angiography (DSA) performance, patients were divided into cerebral atherosclerotic stenosis group and no cerebral atherosclerotic stenosis group. According to the location of atherosclerotic stenosis, patients were divided into extracranial atherosclerotic stenosis group, intracranial atherosclerotic stenosis group, intracranial and extracranial atherosclerotic stenosis group. According to the severity of atherosclerotic stenosis, patients were divided into mild group, moderate group and severe group. Clinical data and laboratory indicators were collected. Multifactorial regression was used to analyze the risk factors, Spearman correlation analysis was used to evaluate the relationship between UHR and the degree of stenosis, and the predictive value of UHR for intracranial and extracranial atherosclerotic stenosis was analyzed by the receiver operating characteristic curve. Results A total of 388 patients were included. Among them, 291 cases in cerebral atherosclerotic stenosis group and 97 cases in no cerebral atherosclerotic stenosis group; 85 cases in the intracranial atherosclerotic stenosis group, 123 cases in the extracranial atherosclerotic stenosis group, and 83 cases in the intracranial and extracranial atherosclerotic stenosis group; There were 104 cases in the mild group, 81 cases in the moderate group, and 106 cases in the severe group. The results of multiple logistic regression analysis showed that age, hypertension, UHR and uric acid were independent influencing factors associated with atherosclerotic stenosis of intracranial and extracranial arteries. Furthermore, the uric acid and UHR were also risk factors for the degree of stenosis (P<0.05). Spearman correlation analysis results showed that UHR was positively correlated with the degree of stenosis (r=0.516, P < 0.001). Receiver operating characteristic curve showed that the predictive value of UHR (area under the curve was 0.724) was superior to that of uric acid (area under the curve was 0.638) or HDL-C (area under the curve was 0.709). It also showed good predictive value for stenosis in different locations of intracranial and extracranial arteries. Conclusion UHR is an independent risk factor for intracranial and extracranial atherosclerotic stenosis with notabla predictive value
