OBJECTIVETo investigate the effect of Buyang Huanwu Decoction (BYHWD) and the different combinations of its ingredients on neurogenesis following ischemic stroke in rats.

METHODSThe model rats of ischemic stroke was established by blocking cerebral media artery with electrocoagulation through craniectomy, and electric stimulation, given from 24 h after blocking, 2 h daily for 15 successive days. They were divided into four groups, Group A treated with saline, Group B treated with BYHWD, Group C treated with BYHWD but earthworm subtracted, and Group D treated with Danggui Buxue Decoction (DGBXD). The expression of 5-bromodeoxyuridine (BrdU) in cerebral tissue was determined by immunohistochemical method.

RESULTSLarge amount of BrdU immunoreactive cells presented in the hippocampal region of rats in Group B and C, densely arranged, partial in cluster, with the figure significantly different to that in Group A (P < 0.01), and the amount in the ischemic side was significantly more than that in the opposite side (P < 0.05). While comparing between Group A and D, the amount of BrdU immunoreactive cells in the hippocampal region showed insignificant difference (P > 0.05).

CONCLUSIONBYHWD has a effect in promoting neurogenesis better than DGBXD.

Aim Toresearchthemolecularmecha-nisms of DADS-induced apoptosis in human leukemia K562cells.Methods Cellviabilitywasmeasuredby MTT. Levels of DADS-induced ROS were measured by 2ˊ, 7ˊ-dichlorofluorescein diacetate ( DCFH-DA) fluo-rescence. DADS-induced mRNA levels of components of the NADPH oxidase were detected by Real-time PCR. The combination of protein Rac2 and p67phox was measured by immunoprecipitation assays. Flow cy-tometry methods were used to determine the percentage of apoptosis cells. DADS-induced Rac2 levels were measuredbyWesternblot.Results TheDADS-trea-ted K562 cells showed a dose-and time-dependent de-crease in cell viability and proliferation. There was sig-nificant up-regulation of the mRNA level of components of the NADPH oxidase complex in K562 cells after treatment with 6 mg·L-1 DADS for 6 h. Western blot results revealed that, compared with the control group, there was a significant up-regulation of Rac2 protein in K562 cells treated with 5. 0 and 10. 0 mg·L-1 DADS for 24h. And Rac2 combined with p67phox in DADS-induced apoptosis in K562 cells. PMA markedly in-creased the percentage of apoptotic cells, and DPI re-duced the percentage of apoptotic cells in DADS-in-duced K562 cells. Levels of DADS-induced ROS, also showed enhancement when exposed in PMA, but there was no DADS-induced ROS production evident when exposed in DPI in DADS induced K562 cells. Conclu-sions TheseresultsindicatethatNADPHoxidaseis the main source of DADS-induced ROS production. Diallyl disulfide induces apoptosis in human leukemia K562 cells through activation of NADPH oxidase.

Objective To discuss imaging classification of blunt traumatic thoracic aortic injury (BTTAI) and weigh guideline value of its imaging classification to surgical options.Methods BTTAI in 12 patients were divided into three types in accordance with outline of aortic injury revealed by CT imaging,i.e.,type A of normal outline of aortic blood vessel but free endothelium in aortic cavity,type B of abnormal aortic outline and contrast extravasation to aortic lumen exterior but only confining to mediastina,and type C of abnormal aortic outline and contrast leakage to thoracic cavity.Significance of BTTAI morphological classification was analyzed according to data,such as systemic injury severity score (ISS),local injury sites,surgical approaches and patients' outcome.Results Multiple injuries combined with BTTAI were observed in all patients whose aortic lesion image could be all generalized by above-mentioned classification.BTTAI image showed type A in three patients,type B in seven and type C in two.Pseudoaneurysm was confirmed as the foremost common BTTAI.There were no significant differences in ISS,hypotension morbidity,treatment methods or mortality between each type of BTTAI.Conclusions BTTAI occurs mostly in multiple injuries and thus overall injury severity assessment is not only depended on aortic lesion classification.BTTAI classification in this study reflects injury severity of vessel wall,takes account to location of lesion and adjacent relations (especially length of landing zone) and hence has accurate referential value for surgical decisions.

Objective To investigate the influential factors on the effectiveness of the first 131I ablation therapy on thyroid remnant and of 131I treatment on metastatic lesions in differentiated thyroid cancer (DTC) patients. Methods Retrospectively,46 DTC cases (divided into complete-ablation group and incomplete-ablation group) of first 131I ablation were enrolled,and 40 DTC cases (divided into remission group and in-remission group) of consecutive 131I treatments on metastatic lesions were enrolled. Influential factors were analyzed (t-test,t'-test,x2-test,Fisher exact test) and logistic regression analysis was performed. Results For the first 131I ablation effectiveness,surgical method,remnant thyroid weight,thyroid stimulating hormone (TSH) level,interval between surgery and 131I ablation therapy,metastatic status were selected as influential factors (x2 = 5. 804,t' = - 5. 258,t' = 7. 376,x2 = 8. 867,x2 = 8. 615,all P ＜0. 05). After logistic regression analysis,formula was obtained as y = 3. 766 - 0. 947x1 ( remnant thyroid weight) -3. 149 x2 (lymph node metastasis) -3. 373 x3 (distant metastasis). For metastatic treatment effectiveness,remission rate of papillary DTC was higher than that of follicular DTC,remission rate of patients with lymph node metastasis was higher than that of distant metastasis,remission rate of total thyroidectomy was higher than that of other types of thyroidectomy ( Fisher exact test,x2 = 7. 278,P ＜ 0. 05 ). In remission group,serum TSH level was much higher and thyroglobulin (Tg) level was much lower before the first ablation therapy (t =4. 489,t' = -4.906,all P ＜0.01 ). After logistic regression analysis,formula was obtained as y = - 0. 363 + 0. 065 x4 ( TSH level) - 0. 250 x5 ( Tg level). Conclusions Influential factors of success rate of the first 131I ablation therapy included surgical method,remnant thyroid weight,TSH level,interval between surgery and 131I ablation therapy and metastatic status,while determinant factors were thyroid remnant weight,lymph node metastatic status and distant metastatic status. The influential factors of success rate of 131I treatment on metastatic lesions included pathological type,surgical method,metastatic status,TSH level and Tg level,while determinant factors were TSH level and Tg level before the first 131I ablation therapy.

Batifiban, a synthetic cyclic peptide, is a potent platelet glycoprotein GPIIb/IIIa antagonist which may be useful in the treatment and prevention of acute coronary syndromes. The pharmacokinetics and pharmacodymanic (inhibition of platelet aggregation) effects, and tolerability of batifiban were investigated in healthy subjects following single bolus injection with doses of 55, 110, or 220 microg/kg, or multiple doses of an bolus followed intravenous infusion for 24 h (180 microg/kg plus 2.0 microg/min.kg, and 220 microg/kg plus 2.5 microg/min.kg) in this phase I clinical trial. Plasma levels of batifiban and areas under the curve were found to be proportional to doses. Batifiban was rapidly eliminated with a half-life of approximately 2.5 h. Significant differences were noted for plasma levels of batifiban and areas under the curve between males and females. No significant differences in the terminal half-life were found between males and females. Batifiban reversibly inhibited ex vivo platelet aggregation in a dose- and concentration-dependent manner, consistent with its mechanism as a GPIIb/IIIa antagonist. Single and multiple intravenous doses of batifiban were found to be safe and well tolerated in healthy subjects. These results support a bolus injection plus intravenous infusion regimen of batifiban for the treatment and prevention of acute coronary syndromes.
