Objective To explore the effect of aspirin combined with clopidogrel bisulfate in the treatment of patients with acute cerebral infarction.Methods 486 patients with acute cerebral infarction were selected and divided into the two groups in accordance with the random number table,243 cases in each group.The control group were given aspirin and conventional medical treatment.The observational group were given aspirin and clopidogrel bisulfate orally,system hemorrhage and TT,PT,APTT,FIB of both group were monitored.The efficacy was analyzed in accordance with the degree of neurological deficits score.Results The NIHSS of the observational group after treatment [(6.38 ± 1.19) points] was significantly lower than that of before [(15.04 ± 2.53) points] (P ＜ 0.05);The NIHSS of the control group after treatment [(9.45 ± 3.27) points] was significantly lower than before [(16.26 ± 2.71) points] (P ＜ 0.05);The NIHSS after treatment in the observational group [(6.38 ± 1.19) points] was significantly lower than that of the control group [(9.45 ± 3.27) points] (t =8.264,P ＜ 0.05).The total effective rate of the observational group was 94.24％,which was significantly higher than 81.48％ of the control group(x2 =11.485,P ＜ 0.05).No system hemorrhage was found in both groups.The coagulation index after treatment was higher than before but still in relatively safe range.There was no significant difference of coagulation index between observational group and control group (all P ＞ 0.05).Conclusion Using aspirin combined with clopidogrel bisulfate in acute cerebral infarction patients is safe and effective.

The sterile stem tips, nodular and non-nodular stem of Morinda officinalis How were cultured in vitro. The results showed that the most suitable procedure for sterilization of explants was soaking into 0.1% HgCl 2 solution for 10 to 15 minutes after pretreating with 70% ethanol for 30 seconds. MT culture medium with BA was effective to induce direct shooting of stem tips and nodular stem, the shooting rate of nodular stem being 97.5% . The optimal BA concentration was 1 mg?L -1 , the shooting rate would decrease when the concentration of BA increased. As for the induction of rooting, MT culture medium adding with 0.2 to 0.5 mg?L -1 NAA was optimal, the rooting rate being over 80.0% .

Objective To find out technological evidence for the rapid propagation of Aloe vera L.var.chinensis (Haw.)Berber. Methods The technique of plant tissue culture was used to study the rapid propagation of Aloe vera L.Var.Chinesis(Haw.)Berger.The shoot growing from the underground stem of Aloe vera L.Var.chinensis(Haw.)Berger was taken as the explant to induce fascicular bud. Results The optimal culture medium was MT.MT culture medium added with 6-benzylaminopurine(BA) was effective to induce the shoot formation and increase the direct shooting rate.The optimal BA concentration for the induction and formation of shoot was 2 mg?L -1 ,the shooting rate being 100%.As for the induction of rooting,MT culture medium adding with 0.5 mg?L -1 naphthalene acid was optimal,the rooting rate being 100%. Conclusion The culture of Aloe shoot growing from the underground stem,proper culture medium and BA concentration are important for the rapid propagation of Aloe.
