OBJECTIVE:To evaluate the clinical efficacy of Shuanghuanglian injection in the treatment of acute exacerbation of chronic obstructive pulmonary disease (AECOPD),and to observe its effects on the plasma levels of C-reactive protein (CRP),procalcitonin(PCT)and interleukin-6(IL-6). METHODS:A total of 100 AECOPD patients were randomly divided into observation group and control group,with 50 cases in each group. Control group received routine treatment,such as controlled oxygen therapy,intravenous dripping of moxifloxacin,bronchodilator for relieving asthma,mucolytic for eliminating phlegm,nu-tritional support. Observation group was additionally given Shuanghuanglian injection 1 ml/(kg·d)added into 5% Glucose injec-tion 250 ml intravenously,qd,on the basis of control group. Treatment course of 2 groups lasted for 10 d. Clinical efficacies of 2 groups were compared as well as the changes of serum levels of CRP,PCT and IL-6 before and after treatment and the occur-rence of ADR. RESULTS:After treatment,total effective rate of observation group was 96.0%,which was significantly higher than 82.0% of control group,with statistical significance(P<0.05). Before treatment,there was no statistical significance in se-rum levels of CRP,PCT and IL-6 between 2 groups (P>0.05). After treatment,serum levels of CRP,PCT and IL-6 were de-creased significantly in 2 groups,and those of observation group were significantly lower than those of control group,with statis-tical significance (P<0.05). There was no statistical significance in the incidence of ADR between 2 groups (P>0.05). CON-CLUSIONS:Shuanghuanglian injection can effectively improve serum inflammatory factors of AECOPD patients,and shows good clinical efficacy and safety.

Ten cell strains were obtained from the human gastric cancer cell line BGC-823 by using the method of single cell cloning. Through inoculation of these cell strains in nude mice and subsequent observation of their metastatic capability, four cell lines, C_1, C_6 with high, and C_5, C_8 with low metastatic capability were selected out; and their biological and morphological properties were studied. It was demonstrated that all of them did not show apparent difference in growth ability, but morphologically, the mictovilli of C_5 and C_8 cells were scarce and short; and their microfilaments were thick, straight and well organized. Whereas the microvilli of C_1 and C_6 strains were long and abundant comparatively, but their microfilaments were poorly organized. On the basis of present observation,we suggested that the organization of microfilaments in cancer cells appeared to bear reversed relationship with their metastatic capability.
