Objective To determine the occurrence and baseline predictive factors of early neurological deterioration ( END) among mild ischemic stroke patients.Methods Mild ischemic stroke patients admitted in the hospital were prospectively enrolled.Univariate and multivariate Logistic recession analyses were used to analyze the demographic data, risk factors of ischemic stroke, clinical, brain imaging and laboratory data.Risk factors of END were identified.Results From June 2012 to August 2013, a total of 319 patients with mild ischemic stroke were enrolled, 45 patients (14.1%) of them experienced END.Univariate analysis showed that baseline NIHSS ( U=3522.000,P=0.000), baseline systolic blood pressure (t=2.871,P=0.004), proportion of symptomatic large artery severe stenosis or occlusion (χ2 =52.564,P=0.000) and proportion of large artery atherosclerosis among TOAST subtypes (χ2 =47.287,P=0.000) in END group were significantly higher than those in non-END group. Multivariate logistic regression analysis showed that baseline systolic blood pressure>142 mmHg (1 mmHg=0.133 kPa) (OR=3.954, 95%CI:1.693-9.236, P=0.001), symptomatic large artery severe stenosis or occlusion (OR=3.170, 95%CI:1.170-8.583, P=0.023) and baseline NIHSS (OR=2.038, 95%CI:1.359-3.057, P=0.001) were associated with END.Conclusions About 14.1% of the mild ischemic stroke patients can occur END.Baseline systolic blood pressure>142 mmHg, symptomatic large artery severe stenosis or occlusion and higher baseline NIHSS were the independent risk factors of END.

Objective To investigate the functional outcome in patients with mild ischemic stroke and to identify its risk factors for poor outcome.Methods The patients with mild ischemic stroke treated within 72 hours after onset were enrolled prospectively.According to modified Rankin Scale (mRS) scores at day 90 after onset,the patients were randomly divided into either a poor outcome group (mRS score ＞2) or a good outcome group (mRS scores 0-2).Univariate analysis and multivariate logistic regression analysis were used to compare and analyze the demographic data,vascular risk factors,clinical data,laboratory data,imaging data,and follow-up data.The risk factors for poor outcome in patients with mild ischemic stroke were identified.Results A total of 253 patients with mild ischemic stroke were enrolled,and 71 of them (28.1％) had poor outcome.Univariate regression analysis showed that the patients' proportions of age (t =2.037,P =0.043),baseline National Institutes of Health Stroke Scale (NIHSS) score (U =4 610.000,P =0.000),baseline mRS score (U =5 723.000,P =0.000),as well as previous history of ischemic stroke (x2 =4.950,P =0.026),severe symptomatic artery stenosis or occlusion (x2 =49.037,P =0.000),large artery atherosclerotic stroke (x2 =34.359,P =0.000),early neurologic deterioration (x2 =45.804,P =0.000),complicated by pneumonia (x2 =12.121,P =0.000) and recurrent ischemic stroke (x2 =14.305,P =0.000) of the poor outcome group were significantly higher than those of the good outcome group.Multivariate logistic regression analysis showed that advanced age (odds ratio [OR] 1.049,95％ confidence interval [CI] 1.012-1.086; P =0.008),higher baseline mRS score (OR,2.130,95％ CI 1.212-3.743;P=0.009),higher baseline NIHSS score (OR 1.532,95％ CI 1.064-2.206; P=0.022),severe symptomatic large artery stenosis or occlusion (OR 7.569,95％ CI 3.497-16.380; P=0.000),early neurological deterioration (OR 7.369,95％ CI 2.648-20.510; P =0.000) and recurrent ischemic stroke (OR 10.450,95％ CI 3.071-35.564; P =0.000) were the independent risk factors for poor outcome.Conclusions More than one fourth of the patients with mild ischemic stroke had poor outcome.Advanced age,higher baseline mRS score,higher baseline NIHSS score,severe symptomatic large artery stenosis or occlusion,early neurological deterioration,and recurrent ischemic stroke were the independent risk factors for poor outcome.

Objective: To investigate the mental health status of railway female workers and related influencing factors, and to provide a scientific strategy for labor protection regulations in railway female workers. Methods: Cluster sampling was used to select 5033 female workers from Jinan, Nanning, Qinghai-Tibet, and Wuhan railway systems in China from January to August, 2016. A uniform reproductive health questionnaire, as well as the Symptom Checklist-90 (SCL-90) , was used to investigate their general information (age, marital status, education level, and family income) , work type (day shift, night shift, or work on shift) , work position, and the presence or absence of exposure to occupational hazardous factors. The score on each factor of SCL-90 and the positive rate of mental health status were calculated. Results: The positive rate of mental health status was 10.6% in railway female workers. The workers exposed to occupational hazardous factors had a significantly higher positive rate of mental health status than those not exposed to occupational hazardous factors (14.20% vs 8.02%, P<0.01) . There were significant differences in the positive rate of mental health status between workers with different ages, marital status, education levels, histories of abortion, or annual family income levels (P<0.01) . The scores of somatization (1.54±0.62) and horror (1.28±0.47) in SCL-90 were significantly higher than the Chinese adult norm (P<0.01) . The multivariate logistic regression analysis showed that exposure to occupational hazardous factors, night shift, overwork, and carrying heavy objects were associated with mental health problems (OR=1.797, 95%CI: 1.393-2.318; OR=0.641, 95%CI: 0.498-0.827; OR=0.586, 95%CI: 0.439-0.783; OR=0.580, 95%CI: 0.378-0.890) . Conclusion Railway female workers have lower levels of mental health than the general population and are under significant occupational stress. Exposure to occupational hazardous factors, night shift, overwork, and carrying heavy objects are associated with the development of mental health problems in railway female workers.

OBJECTIVETo study the antiangiogenetic and tumor inhibitory effects of endostatin (Es) by intratumoral versus intravenous administration combined with adriamycin (Adm) for treatment of transplanted tumor in mice.

METHODSForty mice were subjected to subcutaneous implantation of H22 cells and randomly divided into 4 groups by the body weight when the tumor diameter reached 1 cm, namely the control group (with intratumoral and intravenous injection of normal saline), Es intratumoral group (with intratumoral injection Es and intraperitoneal Adm injection), Es vein group (with intravenous Es injection and intraperitoneal Adm injection), and Adm group (with intratumoral saline injection and intraperitoneal Adm injection). The tumor volumes and tumor inhibition rates were calculated, and the expression of vascular endothelial growth factor (VEGF) and the microvessel density (MVD) of the tumors were examined, with the survival time of the mice also observed.

RESULTSThe tumor volume was smaller in Es intratumoral group than in the other groups (P<0.05). The expression of VEGF and M VD in Es intratumoral group was significantly decreased as compared with that in the other groups (P<0.05). The survival time was significantly longer in Es intratumoral group and Es vein group than in the other groups (P<0.05), but showed no significant difference between Es intratumoral group and Es vein group (P>0.05).

CONCLUSIONIn combination with Adm regimen, Es given intratumoral injection produces better effect than intravenous Es injection against angiogenesis and tumor growth, no significant difference can be found in the survival time between them.
