Ginsenosides, belonging to a group of saponins with triterpenoid dammarane skeleton, show a variety of pharmacological effects. Among them, some ginsenoside derivatives, which can be produced by acidic and alkaline hydrolysis, biotransformation and steamed process from the major ginsenosides in ginseng plant, perform stronger activities than the major primeval ginsenosides on inhibiting growth or metastasis of tumor, inducing apoptosis and differentiation of tumor and reversing multidrug resistance of tumor. Therefore ginsenoside derivatives are promising as antitumor active compounds and drugs. In this review, the derivatization methods, ginsenoside derivatives and their anti-tumor structure-activity relationship have been summarized for providing useful information for the research and development of novel antitumor drugs.

Objective: To express vascular basement membrane-derived multiple peptide (VBMDMP) in Pichia pastoris and to identify its bioactivity. Methods: PCR technique was used to obtain the target fragment GST-VBMDMP, which was then cloned into pPIC9K vector. The resultant vector pPIC9K-GST-VBMDMP was transfected into Pichia pastoris cells with spheroplast and the positive recons was identified. The His + Muts transformant was shake-cultured in MGY at 30 ℃. The culture supernatant (1 ml) was collected for preservation at-70 ℃ every 24 hours while maintaining the concentration of methanol at 0.5% in the culture medium. SDS-PAGE analysis was used to detect the protein expression after 8 days and then animal and cell experiments were performed with GST-VBMDMP. Results: SDS-PAGE analysis found that protein express increased during 1-7 days and decreased after 8 days in MGY medium; GST-VBMDMP fused protein was obtained by Glutathione Sepharose 4B and it inhibited the artery endothelial cell tube structure formation in C57BL/6 mouse; GST-VBMDMP( 2, 6, 10 mg/kg)also significantly inhibited the primary cancer Lewis mouse (tumor inhibitor rates being 96.6%, 82.1%, and 61.2%, respectively)and metastatic lung tumors(tumor inhibitor rates being 96.8 %, 87.9 %, and 75.3%, respectively)(P

Objective To observe and study the influence degree of strengthen training for family members for the treatment compliance and unhealthy lifestyle of patients with diabetes mellitus. Methods A total of 64 patients with diabetes mellitus from January 2015 to March 2016 were selected and divided into two groups by the method of random number table,32 patients in control group were taken care with routine nursing of diabetes mellitus,32 patients in observation group were taken care with strengthen training for family members,then the treatment compliance,related knowledge cognition of unhealthy lifestyle and unhealthy lifestyle situation of two groups before the intervention and at 4th, 8th and 12th week after the intervention were compared. Results The treatment compliance, related knowledge cognition of unhealthy lifestyle and unhealthy lifestyle situation of two groups before the intervention all had no obvious differences (all P>0.05). The treatment compliance at 4th, 8th and 12th week after intervention were (6.26 ± 0.32), (6.95 ± 0.36), (7.28 ± 0.40) scores in observation group, and (5.23 ± 0.29), (6.01 ± 0.30), (6.30 ± 0.33) scores in control group, and the differences were significant (t=8.253, 9.201, 10.257, all P<0.05). The related knowledge cognition of unhealthy lifestyle at 4th, 8th and 12th week after intervention were (80.78±5.90), (89.44±6.02), (93.43±6.20) scores in observation group, and (73.38± 5.73), (77.93±5.84), (82.20±6.01) scores in control group, and the differences were significant (t=11.258,12.563, 13.324, all P<0.05 ). The unhealthy lifestyle situation at 4th, 8th and 12th week after intervention were 75.00%(24/32), 90.63%(29/32), 96.88%(31/32) in observation group, and 59.38%(19/32), 68.75%(22/32),78.13%(25/32) in control group, and the differences were significant (χ2=7.251, 7.468, 9.169, all P<0.05). Conclusions The influence of strengthen training for family members for the treatment compliance and unhealthy lifestyle of patients with diabetes mellitus are more active, so the value of strengthen training for family members of patients with diabetes mellitus is higher.

Miscanthus sinensis Anderss is a perennial C4-grass. It is a promising bioenergy plant, which has been proposed as general feedstock for biomass and lignocellulosic biofuel production. In this study, the flower and leaf buds transcriptomes of Miscanthus sinensis Anderss were sequenced by the platform of Illumina HiSeq 2000. In total 98 326 Unigenes were generated by de novo assembly with an average length of 822 bp and N50 of 1 023 bp. Based on the NR, NT, Swiss-Prot, KEGG, GO and COG databases (Evalue < le-5), 74 134 (75.40%) Unigenes were annotated. A total of 45 507 Unigenes were mapped into different GO terms. In KEGG pathways identification, 36 710 sequences were assigned to 128 KEGG pathways. Sorghum bicolor (37 731, 60.86%), Zea mays (16 258, 26.22%), and Oryza sativa (3 065, 4.94%) showed high similarity to Miscanthus sinensis Anderss. And 24 photosynthesis-related enzyme genes were identified. The result provides a foundation for further characterizing the functional genes in Miscanthus sinensis Anderss.

Objective To investigate the expression and significance of myeloperoxidase(MPO) in acute lungs injury of severe acute pancreatitis associated ascetic fluid. Methods Forty-five adult wistar rats were randomly assigned into the group of negative control (group C,n=15),the group of severe acute pancreatitis (group S,n=15) and the group of peritoneal injection (group E,n=15). The group C was cut peritoneum and flipped pancreases softly. In group S,3.5% sodium taurocholate was injected retrograde in pancreatic and bile duct to establish the model of severe acute pancreatitis,and the pancreatic homogenate and ascites of the group S was injected into abdominal cavity of group E rats. After animal model established,rats were killed at 3h,6h and 12h point. The blood of inferior vena cava was sucked for determination of amylase.The inferior lobe of left lung was cut for myeloperoxidase detection.And pathology was regularly done about pancreas and lungs. Results Interstitial edema,hemorrhage and infiltration of neutrophilic granulocyte and macrophage were observed in group S and E. At different time point,the amylase levels of blood and myeloperoxidase of lungs in group S and E were significantly higher than those of group C,and the increasing degree of group E was smaller than group S. Conclusion Acute lung injury can be induced by the severe acute pancreatitis associated ascetic fluid. The expression of myeloperoxidase of lungs was increased to induce acute lungs injury.The reason may be concerned with activation of granulocyte by severe acute pancreatitis associated ascetic fluid.
