Objective To study the variation of acute blood pressure in different subtypes of first ischemic stroke,and investigate the influence on the prognosis.Methods A total of 710 patients with first ischemic stroke were selected.The blood pressure levels were monitored during the initial 7 hospital days.Clinical outcome was based on the combined analysis of Barthel index and the National Institute of Health Stroke Scale (NIHSS) score on the 180th day.In the subtypes of large artery atherothrombosis(LAA),cardioembolism (CE),small artery disease occlusion (SAO) were 400,160,150 cases.Logistic regression model was used to estimate the influencing factors on the prognosis.Results An U-shaped effect was observed in different subtypes between blood pressure on admission,average acute blood pressure and prognosis.In the subtypes of LAA and CE,those who had a basehne systolic blood pressure (SBP) of 140-159 mm Hg (1 mm Hg =0.133 kPa) or a baseline diastolic blood pressure (DBP) of 90-99 mm Hg on admission got good prognosis.In the subtypes of SAO,those who had a baseline blood pressure of 130/95 mm Hg on admission got good prognosis.In all subtypes,the average blood pressure of 150/95 mm Hg got good prognosis.In the subtypes of LAA and CE,those who had a baseline SBP of 120-159 mm Hg or a baseline DBP of 80-99 mm Hg within 7 d after admission got good prognosis.In the subtypes of SAO,those who had a baseline blood pressure of 140/90 mm Hg within 7 d after admission got good prognosis.In all subtypes,the average blood pressure of 140/90 mm Hg within 7 d after admission got good prognosis.Logistic regression analysis revealed that the decrease of blood pressure during the first 24 hours,deterioration within 7 d after admission,acute complication,NIHSS score on admission were the independent risk factors of prognosis,while antihypertensive therapy in the acute phase was the independent protection factor in the subtypes of LAA and CE.In the subtypes of SAO,acute complication was the independent risk factor of prognosis.Conclusions An U-shaped effect is observed in different subtypes between blood pressure on admission and prognosis.In the subtypes of LAA and CE,the decrease of blood pressure during the first 24 hours,deterioration within 7 d after admission,acute complication,NIHSS score on admission are the independent risk factors of prognosis.

Objective To elucidate the relationship between quality of life (QOL) and disease activity of systemic lupus erythematosus (SLE),as well as to reveal the factors impacting disease activity and the QOL of SLE utilizing the combination of SLE-specific quality of life questionnaire (SLEQOL) and the medical outcomes survey short form 36 (SF-36).Methods SLEQOL and SF-36 health survey questionnaire were applied.Information on gender,disease duration,age,education level were collected.Serum complement (C3 and C4) level and erythrocyte sedimentation rate (ESR) were measured.Patients were divided into inactive,mild active,moderate active and severe active respectively according to SLE disease activity index (SLEDAI).Pearson's product moment correlation coefficient was used to analyze the correlation between the activity of disease and the QOL.Multiple linear regression was employed to explore the factors which could impact on SLEQOL.Results The physical function of SLEQOL was positively correlated with SLEDAI (r=0.36; P＜0.05).The association between reported health transition of SF-36 and SLEDAI was positive (r=0.19; P＜0.05).Physical functioning,role-physical,role-emotional,body pain and vitality were all negatively correlated with SLEDAI (r:-0.20,-0.19,-0.19,-0.19,-0.21 respectively; P＜0.05).The scores of patients with severe disease activity were significantly increased in the physical functioning of SLEQOL than other three groups (18±10 vs 11±5,12±6,13±7; P＜0.05).Scores on the Health transition of patients with moderate and severe disease activity were lower than those of whom with mild disease activity (23±28.14±17 vs 34±39,P＜0.05).Patients with mild or severe disease activity had lower score than those of patieuts in disease inactive (30±41,34±39 vs 44±44,P＜0.05).Multiple linear regression analyses showed that disease duration and education level might be the influencing factors of SLEQOL.Conclusion QOL of patients with SLE is related to the level of disease activity and is impacted by disease duration and education.

Cancer is one of the main causes of death for human beings. Clinical oncologists increasingly rely upon imaging for diagnosis, stage, response assessment, and follow-up in cancer patient. However, 18F-FDG is not a tumor specific agent, inflammation and infection also have intensive uptake of 18F-FDG, resulting in false positive diagnosis, and some tumors have low uptake of 18F-FDG or even do not uptake 18F-FDG, leading to false negative diagnosis. So it is urgent to develop non-18F-FDG novel tumor targeting agent. Recently, a large number of researches in vitro have demonstrated that berberine has anti-tumor activity against a variety of tumor cells by inducing tumor cell apoptosis through inhibition of mitochondrial respiratory chain etc. So far, there is no credible evidence of berberine targeting in tumor in vivo. We proposed a hypothesis that berberine has the characteristics of tumor targeting biodistribution in vivo, and verified the proposal by 18F-berberine PET/CT imaging in VX2 muscle tumor-bearing rabbit model. In this review, we intend to give an overview of the progress of berberine anticancer, the structural bases of berberine anticancer and the uderlying molecular mechanisms of berberine anticancer indentified so far. We also introduce the first visualization of 18F labeled berberine derivatives targeting tumor in VX2 muscle tumor-bearing rabbit model by PET/CT. These breakthrough findings suggest that 18F-berberine derivatives as a potential PET/CT tumor targeted molecular imaging agent may have important implications for cancer targeting therapy, molecular imaging and modernization of Traditional Chinese Medicine.
