ABSTRACT
Objective:To investigate the clinical characteristics and outcomes in patients with wake-up stroke.Methods:From January 2019 to December 2019, consecutive patients with acute ischemic stroke admitted to the Department of Neurology, Huizhou Municipal Central Hospital were enrolled retrospectively. The modified Rankin Scale was used to evaluate the outcome of patients at 90 d after the onset. 0 to 2 was defined as a good outcome, and >2 was defined as a poor outcome. Multivariate logistic regression analysis was used to determine the factors affecting the poor outcome of patients with wake-up stroke. Results:A total of 356 patients with acute ischemic stroke were enrolled, including 97 (27.2%) wake-up stroke, and 259 (72.8%) non-wake-up stroke. The National Institutes of Health Stroke Scale (NIHSS) score at admission and the proportion of patients with atrial fibrillation, moderate to severe stroke and cardiogenic embolism in the wake-up stroke group were significantly higher than those of the non-wake-up stroke group, and the proportion of patients with small artery occlusion was significantly lower than that in the non-wake-up stroke group (all P<0.05). Moreover, the proportion of patients with poor outcome in the wake-up stroke group was significantly higher than that in the non-wake-up stroke group (36.1% vs. 24.7%; χ2=4.546, P=0.033). In the wake-up stroke group, 62 patients (63.9%) had a good outcome, and 35 (36.1%) had a poor outcome. The NIHSS score at admission and the proportion of patients with atrial fibrillation and moderate to severe stroke in the subgroup with poor outcome were significantly higher than those in the subgroup with good outcome, and the proportion of patients receiving intravenous thrombolysis and mechanical thrombectomy was significantly lower than those in the good outcome subgroup (all P<0.05). Multivariate logistic regression analysis showed that moderate to severe stroke (odds ratio [ OR] 6.674, 95% confidence interval [ CI] 2.223-20.034; P=0.001) was independently associated with the poor outcome in patients with wake-up stroke, while intravenous thrombolysis ( OR 0.102, 95% CI 0.017-0.630; P=0.014) and endovascular mechanical thrombectomy ( OR 0.108, 95% CI 0.023-0.506; P=0.005) were independently associated with the good outcome of patients with wake-up stroke. Conclusions:In patients with wake-up stroke, the proportion of cardioembolism is higher, the clinical symptoms are more serious and the incidence of poor outcome is higher. The severity of stroke at admission is associated with poor short-term outcome, and intravenous thrombolysis and endovascular mechanical thrombectomy can improve the outcome in patients with wake-up stroke.
ABSTRACT
ObjectiveTo examine the clinical features of fractures and related risk factors in patients with rheumatoid arthritis(RA) in China.MethodsSix hundred and eighty-one RA patients were randomly selected from department of rheumatology of 18 hospitals of China.Data were obtained from the questionnaire,including age,sex,disease duration,the involvement of joints,treatment regimen,features of fractures etc.The possible risk factors of fracture in patients with RA were analyzed with a multi-variate Logistic regression analysis.Results① In 681 RA patients of the survey,48 patients had 54 fractures,and the incidence of fractures was about 8％.② Fractures occurred at various sites.Foot/ankle,femur,spine and wrist were the mostfrequent sites.③ The Logistic regression analysis showed that several factors increased the risk of fracture in RA patients,including long disease duration (OR:1.245,95％CI:0.987-1.570,P=0.065),male gender(OR:0.433,95％CI:0.199-0.942,P=0.035),more deformed joints(OR:1.042,95％CI:1.006-1.079,P=0.023),family history of RA (OR:2.201,95％CI:0.984-4.923,P=0.055),and high scores of SF-36(OR:1.017,95％CI:1.002-1.033,P=0.028).④ According to the degree of correlation from strong to weak,the risk factors of fracture were disease duration,SF-36,sex,number of deformed joints and family history of rheumatoid arthritis.ConclusionThe incidence of fracture is high in patients with rheumatoid arthritis.Several factors could increase the risk of fractures in RA patients,including long disease duration,male gender,more deformed joints,and family history of RA.In order to prevent the occurrence of fractures,cautions should be taken to prevent the development of fractures and treat the disease aggressively to suppress the disease activity of RA.
ABSTRACT

The quality of Chinese herbal medicine is closely related to its producing region. In order to apply mathematical models to do a quantitative study on the suitability of Chinese herbal medicine, it is necessary to study on the ecological factors and the interpolation of climatic data, which influence the Chinese herbal medicine growth. The paper firstly studied the judgment standard of ecological index from the points of ecology and statistics, and how to calculate the optimum range values and the weight of each ecological factor. Secondly, meteorological element data is essential data in analyzing the suitable region of Chinese herbal medicine, and the spatial distribution of meteorological elements is closely related to terrain environment, so, in order to make the results close to true value by the greatest degree. The paper adopted multiple linear regression interpolation method which based on DEM. The paper distinguished the factor system of suitable region and interpolation on the point of datumization, and made a study on it about some key issues.

Objective To investigate the blood pressure control effect of captopril sustained-releasetablets based combination, antihypertensive therapy on hospitalized high-risk patients with hypertension in high altitude region. Methods According to the blood pressure,risk factors and combined target organ damage,331 hospitalized patients with essential hypertension were divided into 2 groups and accepted different treatment:low-risk group had monotherapy (n=102) , and night-risk group had captopril sustained-release-tablets based combination antihypertensive therapy (n =229). The discharge blood pressure,extent of SBP/DBP decrease and the compliance rate of discharge blood pressure of two groups were compared. Results The extent of SBP/DBP decrease in hight-risk group was significantly greater than low-risk group (SBP [36. 83 ± 22. 23] mm Hg vs.[28. 74 ±18.71] mm Hg,t=-3. 207,P 0. 05;DBP[80. 67 ±9. 82]mm Hg vs. [78. 40 ±9. 97]mm Hg,t =-1.910,P > 0. 05). Furthermore we found no significant difference in the control rate of blood pressure between high-risk and low-risk group (72. 06% vs. 71. 57% , x2 = 0.928, P > 0. 05). Conclusion The captopril sustainedrelease-tablets based combination antihypertensive therapy is a reliable treatment in high-risk patients with hypertension from high altitude region,which shows satisfying blood pressure control rate.
ABSTRACT
Objective To describe the distribution of medication costs of rheumatoid arthritis patients, and to analyze the factors that may affect the costs. Methods Data were obtained from a 12-month retrospective investigation of patients with rheumatoid arthritis (RA) across China. Department of Rheuma-tology of 18 hospitals were randomly selected. The data about their social conditions, clinical conditions, medications associated with RA such as disease-modifying antirheumatic drugs (DMARDs), non -steroidal anti -inflammtory drugs (NSAIDs), steroids, biologic agents were collected, and the costs of drugs were calculated. A non-parameter test and multivariate logistic regression analysis were performed. Results Six hundred and forty six patients were enrolled into the study, 435 completed data were chosen for analysis. The results demonstrated that the average costs per patient for medications in the past year was 8018 . The total medication costs were further subdivided into the following parts: DMARDs, (represented 20% of the total costs), biologic drugs (49%), NSAIDs (4%), herbal drugs (22%), steroids (1%). Data analysis showed that patients with higher education and higher incomes, with medical insurance,better health function status and outpatients paid more on DMARDs. Extra-articular manifestations increased the odds of the high-cost group (OR: 2.180, 95%CI: 1.335～3.558, P=0.002), while poor health function status increased the probability of paying high costs (OR: 1.373, 95%CI: 1.012～1.863, P=0.041). Conclusion High medication costs in RA do exist in RA patients. The costs of medication is associated with health function status and the presence of extra-articular manifestations.
ABSTRACT
Background Quality of life(QOL) refers to the person's subjective appraisal of well-being,life satisfaction,health and functional performance. For those stroke patients who cannot finish the scale themselves,we can try the proxy measurement. However,until recently no QOL scale for proxies were induced to Chinese stroke patients. The goal of this research is to translate and test the SIS 3.0 for proxy,and differences between patient and proxy scores. To translate and test the SIS 3.0 for proxy, and analyzed differences between patient and proxy scores.Methods Ten pairs of patients and their proxies were involved in the primary test. Two hundreds and thirty-three pairs were involved in the formal test. We analyzed the validity, responsiveness, reliability and feasibility of the SIS 3.0 for proxy, as well as the validity in proxy assessment. Results The feasibility was sufficient. Both Split reliability and α coefficient were more than 0.8, demonstrating SIS a reliable instrument. SIS had a good content validity with correlation coefficient more than 0.6. Good criterion validity was established by comparing the scores on various domains to standardized measures with P=0.000. Construct validity was also good as indicated by factor analysis. Proxy scores were significantly different across OHS scales which showed domain responsiveness was good. Comparison of patient and proxy responses resulted in no significant difference. Conclusions SIS for proxy is satisfactory for chinese patients. It is feasible to use a proxy respondent to answer questions on the patient's behalf.
