AIM To study the role of survivin on the apoptosis of lung cancer cell line induced bycisplatin (DDP) and etoposide (VP16). METHODS The lung adenocarcinoma cell line A549 was chosen in this experiment. The inhibitory effects of chemotherapeutical drugs on A549 cell line were assayed with MTT test. Cultured cells was divided into 3 groups: DDP, VP16 and control. Both DDP and VP16 group were divided into high concentration group and low concentration group, respectively. Expression of survivin gene were detected by reverse transcriptase PCR. Apoptosis was deterinined by flow cytometry. RESULTS Both DDP and VP16 obviously inhibited the lung cancer cell growth with dose and time dependent. Apoptosis and inhibitory rate of survivin gene expression induced by chemotherapeutical drugs was higher than that of control group. The effects also were time dependent. CONCLUSION The inhibition of survivin gene expression may play a critical role on the lung cancer cell apoptosis induced by DDP and VP16.

Objective To observe the clinical therapeutic effect of Astragalus injection combined with sub-hibernation therapy for treatment of patients with severe craniocerebral injury.Methods A retrospective research method was conducted, and 89 cases with severe craniocerebral injury admitted to the Department of Critical Care Medicine of the First People Hospital of Baiyin in Gansu Province from January 2010 to December 2016 were enrolled. Astragalus injection combined with sub-hibernation was applied for treatment of 45 patients in the observation group, and for another 44 cases assigned in the control group, simply conventional treatment was used. The Glasgow coma score (GCS), coma time, ratio of cripple, mortality, incidences of pulmonary infection and urinary tract infection were compared between the two groups.Results After treatment, GCS scores were significantly higher than those before treatment in both groups, but the degree of increase was more marked on the 30 days after treatment in the observation group than that in the control group (13.15±2.53 vs. 8.79±1.59,P < 0.05). Compared with the control group, coma time was obviously shorter (days: 5.79±1.89 vs. 13.65±2.73), ratio of cripple [13.33% (6/45) vs. 22.73% (10/44)] and mortality [17.78% (8/45) vs.31.82% (14/44)] were significantly lower in observation group (allP < 0.05); the incidences of pulmonary infection [22.44% (11/45) vs. 31.82% (14/44)] and urinary tract infection [28.89% (13/45) vs. 36.36% (16/44)] were lower in the observation group, but the differences between the two groups were not statistically significant (bothP > 0.05).Conclusions The treatment of Astragalus injection combined with sub-hibernation treatment can significantly improve the coma degree, shorten the time of coma, reduce the mortality and disability rate of patients with severe craniocerebral injury.

Objective To investigate the role of p38MAPK in the differentiation of murine osteoblasts, and to observe the expressions of receptor activator of nuclear factor-κB ligand (RANKL) and osteoprotegerin (OPG). Methods The calvarial osteoblasts of newborn BALB/c mice were cultured in MEM medium containing 10% NCS. Raloxifene (10~(-7) mol/L) and 17β-estradiol (10~(-8) mol/L) were added respectively when cells reached 70%-80% confluence combined with or without 5 μmol/L SB202190, an inhibitor of p38MAPK. The osteoblasts alkaline phosphatase activity assays were performed 72 hours later using PNPP method, and mRNA levels of alkaliphosphatase (ALP), OPG and RANKL were determined by RT-PCR. Results 17β-estradiol and raloxifene increased ALP activity and ALP mRNA level in osteoblasts in vitro which were blocked by p38MAPK inhibitor.The mRNA levels of RANKL and OPG were up-regulated by 17β-estradiol and raloxifene while the ratio of OPG/RANKL kept constant. SB202190 (5 μmol/L) inhibited the highly expressed RANKL and OPG in osteoblasts, and obviously decreased the ratio of OPG/RANKL. Conclusions p38MAPK inhibition blocked the differentiation of osteoblasts and decreased the up-regulated OPG and RANKL expressions in osteoblasts significantly (P<0.05).
