ObjectiveTo observe the effect of Xuesaitong Capsule on stroke patients in recovery phase.Methods427 patients with stroke were randomly divided into 3 groups, group Ⅰ(take in aspirin), group Ⅱ(take in Xuesaitong), group Ⅲ(take both medicine). The Europe Stroke Scale (ESS), Barthel index (BI) and blood rheology were compared among these three groups.ResultsESS and BI score of group Ⅱ were higher than that of group Ⅰ, but lower than that of group Ⅲ. The recurrence rate and blood rheology index was similar in group Ⅰand Ⅱ, but higher than that of group Ⅲ.ConclusionBoth Xuesaitong Capsule and aspirin are effectivity on stroke in recovery phase, but it is better to take in both medicines.

Objective To evaluate a method of fast detection of the hematopoietic progenitor cell (HPC) in peripheral blood samples and explore for an appropriate cutoff value in prediction of adequate CD34+ cell in apheresis concentrate.Methods Peripheral blood samples and apheresis concentrate samples were collected from 27 auto-PBSCT patients receiving chemotherapy plus G-CSF mobilization (chemo group) and 17 patients receiving G-CSF alone (non-chemo group).CD34+ cell counts were determined by flow cytometry according to ISHAGE guideline and HPC counts were detected using Sysmex XE-2100 automatic hemocyte analyzer.The correlation between HPC and CD34+ cell counts in peripheral blood samples and apheresis concentrates were analyzed.Receiver operating characteristic (ROC) curves was used to determine the cutoff value in prediction of adequate CD34+ cell in apheresis concentrate.Results CD34+ cell counts in peripheral blood samples can be estimated by HPC counts (r =0.711,P =0.000,r =0.656,P =0.004).CD34+ cell counts =-0.829+0.648×HPC counts (in chemo group) or 45.033+0.460×HPC counts (in non-chemo group).HPC counts in the peripheral blood of auto-PBSCT patients were highly correlated with the CD34+ cell yield (r =0.602,P =0.001),CD34+ cell counts =1.106+0.046×HPC counts.When HPC in peripheral blood was ≥85/μl,the prediction of adequate CD34+ cells in the yield of apheresis (≥5×106/kg body weight) would have a sensitivity of 78 % and a specifity of 82 %.Conclusion HPC counts in peripheral blood samples in auto-PBSCT patients can be used to determine the optimal time of apheresis and be used as a good marker to predict the stem cell in the yield.

Objective To investigate the relationship between the right-to-left shunt(RLS)detected with contrast-enhanced transcranial Doppler (c-TCD) and recurrent stroke in patients with cryptogenic stroke.Methods The consecutive patients w ith ischemic stroke w ere enrol ed. The patients w ith cryptogenic stroke w ere screened according to the TOAST criteria. They w ere divided into either a RLS positive group or a RLS negative group according to the c-TCD findings, and then they w ere fol ow ed up for a period of one year. They w ere also divided into a recurrent group and a non-recurrent group according to w hether they had recurrence or not. Results A total of 118 patients w ith cryptogenic ischemic stroke w ere enrol ed, including 46 in the RLS positive group, 72 in the RLS negative group, 10 in the recurrent group, and 108 in the non-recurrent group. There w ere no significant differences in demographic and baseline data betw een the RLS negative group and the RLS positive group. There w ere significant differences in RLS positive rate (7/10 vs.39/108; P=0.046) and proportion of patients with server RLS (2/10 vs.1/108; P=0.019) betw een the recurrent group and the non-recurrent group. Multivariate logistic regression analysis show ed that the positive RLS w as an independent predictor of recurrent stroke (odds ratio 4.896, 95% confidence interval 1.135-21.120;P=0.033). Conclusions The positive RLS may be an independent risk factor for the recurrence in patients w ith cryptogenic ischemic stroke.
