Blood pressure variability related to early outcome of acute ischemia stroke in a prospective observational study.

Hypertension is a well-known risk factor for stroke, but the relationship between blood pressure variation (BPV) and prognosis remains unclear. This prospective observational study assessed the association between BPV and early functional outcomes in acute ischemic stroke patients. A total of 871 patients with acute ischemic stroke within 24 h of symptom onset were recruited from the Third Affiliated Hospital of Qiqihar Medical University between 2013 and 2016. Within 6 days of hospitalization, blood pressure was continuously measured from 8:00 to 9:00 every day, and the coefficient of variation (CV) of blood pressure was calculated (including systolic blood pressure [SBP] and diastolic blood pressure [DBP]). The modified Rankin scale was used to evaluate early functional outcomes at discharge. The coefficients of variation of SBP, DBP, and functional outcomes were included as primary outcome variables. Demographic characteristics and medical history were recorded as secondary outcome variables. We found that a greater CV level of SBP and DBP were associated with the poor early functional outcome at hospital discharge, and the odds ratio (OR) and 95% confidence interval (95%CI) of them were 1.56 (1.04-2.35) and 1.99 (1.31-3.03) respectively. A higher standard deviation (SD) of SBP and DBP significantly increased risk of poor early prognosis, OR (95%CI) was 1.78 (1.17-2.71) and 2.25 (1.47-3.45) respectively. Similar results were observed for SBP and DBP. The larger the range of SBP and DBP, the worse is the prognosis. In conclusion, the present study suggests that high BPV is a risk factor for poor early prognosis in acute ischemic stroke.

Inhibition Effect of Ki67 AS-ODN and Its Combination with Paclitaxel on PC-3 Cells / 中药新药与临床药理

Objective To investigate the inhibition effect of Ki67 AS-ODN on pr ostate carcinoma PC-3 cells,and its possible synergism existing in combination of Ki67 AS-ODN and paclitaxel.Methods Ki67 AS-ODN were transfected into PC-3 cells by lipofectamine. Cell proliferation was measured by CCK8 method,and Ki6 7 mRNA expression was detected by RT-PCR. The synergetic effect of Ki67 AS-ODN combined with paclitaxel was evaluated by Zhengjun Jin Q method. Results AS-OD N at the concentration of 31.25 nmol /L can significantly inhibit PC-3 cells pr oliferation(P
