Objective To examine the effects of p38 mitogen-activated protein kinase (MAPK) inhibitor on the behavioral response to zebrafish larvae after hypoxia/reoxygenation brain injury and to identify whether the protective effect is mediated by inhibiting apoptosis and protein,and mRNA related to apoptosis.Methods The 5-day post-fertilization zebrafish larvae were randomly assigned to 3 groups:control group,model group and intervention group.Fishes in the intervention group were separated into 3 subgroups according to p38 MAPK inhibitor concentration (5,10,20 μmol/L).The activity levels of the larvae were analyzed by using quantization mode of ZebraLab software,swimming distance and moving speed were recorded.Terminal transferase dUTP nick end labeling (TUNEL) assays of brain assays were performed.The protein levels of phosphorylation of p38 MAPK,apoptosis related proteins of B-cell lymphoma-2 (Bcl-2),Bcl-2 associated X protein(Bax) and Caspase-3 were determined by Western blot.The mRNA expressions of Bcl-2,Bax,and caspase-3 were also analyzed by reverse transcription-quantitative PCR (RT-qPCR).Results The activity movement analysis of the intervention group 2 and 3 demonstrated a significantly increase in the swimming distance compared with the model group(P ＜ 0.05).After irradiation under strong light,all groups showed dramatically increasing in the moving speed.After removal of strong light,a significant decrease in moving speed was found in the control group and intervention group 2 and intervention group 3.The TUNEL assay showed that apoptosis index decreased in the intervention group (21.7 ±2.0,12.8 ± 1.9,17.7 ±2.6) compared with model group (46.8 ±5.3) (all P ＜0.01).Western blot assays demonstrated a significant increase protein level of phosphorylation of p38 MAPK after hypoxia and reoxygenation,and the inhibitor reduced the p-p38 MAPK expression.Compared with the model group,p38 MAPK inhibitor increased the protein and mRNA expression level of Bcl-2,whereas reduced the Bax and caspase-3 expression in the brain.Conclusions Under the influences of p38 MAPK inhibitor,zebrafish larvae improved the behavioral changes after hypoxia-induced brain injury.The inhibitor (10 μmol/L) optimally reduces hypoxia-induced apoptosis in brain by up-regulating Bcl-2,down-regulating Bax/caspase-3 protein and their mRNA level.

Chitinases genes from Metarhizium anisopliae which is an important entomopathogenic fungus were considered one of the key factors to invade their hosts. One Metarhizium anisopliae HN1 strain was isolated and screened. A chitinase gene was amplified by RT-PCR from Metarhizium anisopliae HN1, The whole length of this gene was 1275bp,and the nucleotide sequence of the gene was 96% similarity to that of the M. anisopliae E6 accessed in GenBank ( AF02749). The gene has been registered in GenBank and its accession number is DQ011865. The gene was subcloned into prokaryon expression vector pET-22b( + ), transformed this recombinant expression plasmid into E. coli strain BL 21 and effective expressed. The SDS-PAGE analysis indicated that the recombinant protein was 42kDa which is same to the reported article. The expression level of recombinant protein was about 63. 3% of whole expressed proteins , And when recombinant E. coli were crushed by freeze and supersonic wave , the activity assay indicates that the chitinase expressed in bacteria possesses biological activity.

60 years) received parenteral nutritional support in the period of perioperation.When parenteral nutrition was applied,average non protein calorie intake was 85.4 kJ/(kg?d), and NPC∶N value was 118∶1. Results:PA,TRF and electrolyte were significantly increased after parenteral nutritional support.The nutritional indices did not change and were kept within normal range during parenteral nutrition. Conclusions:Parenteral nutrition is one of the important perioperative treatments in elderly patients with obstruction caused by colon cancer.It is safe and effective to use parenteral nutrition with low fat and glucose in elderly patients.

Aim To investigate the effects of silencing MALAT1 gene on cell proliferation inhibition and apop-tosis induced by Melittin in human hepatocellular car-cinoma HepG2 cells. Methods The inhibitory rate of cell proliferation treated with Melittin in HepG2 cells was examined by MTT assay. Apoptotic rate was detec-ted by flow cytometry. The MALAT1 expression level in HepG2 cells was measured by qPCR. Specific siR-NAs were utilized to silence MALAT1 expression. The rates of cell proliferation inhibition and apoptosis in HepG2 cells treated with siRNA and Melittin were compared with those of Melittin alone. Results Melit-tin significantly suppressed the growth of HepG2 and induced cell apoptosis in a dose-dependent manner. Compared with normal liver cell lines, MALAT1 was highly expressed in HepG2 cells ( P<0. 05 ) . The ex-pression of MALAT1 in HepG2 cells was inhibited by Melittin, and the inhibitory rate increased with the in-crease of concentration. The rates of cell proliferation inhibition and apoptosis in HepG2 cells treated with siRNA and Melittin were significantly higher than those treated merely with Melittin. Conclusion Melittin can reduce the expression of MALAT1 and silencing MALAT1 can effectively promote proliferation inhibi-tion and apoptosis in HepG2 cells induced by Melittin.

Objective To investigate effect of dexmedetomidine on postoperative analgesia pump dose and effect.Methods 50 cases of patients with abdominal surgery under general anesthesia were selected.According to the postoperative analgesic drugs were divided into control group and experimental group, 25 cases in each group were given corresponding drug treatment.After treatment, the visual analogue scale, comfort score, adverse reaction rate and dosage of analgesic drugs were detected and compared.Results Compared with the control group,the VAS score were lower(P <0.05),the BCS score were higher(P<0.05),the adverse reaction rate were lower(P<0.05),the dosage of analgesic pump were lower(P<0.05). Conclusion Dexmedetomidine can significantly reduce postoperative pain degree of patients, reduce the incidence of adverse reaction, reduce analgesic dosage of the drug pump.

Objective To apply the Intelligent Device for Energy Expenditure and Activity(IDEEA)system to evaluate the locomotion of patients with protrusion of intervertebral disc(PID)quantitatively and dynamically.Methods 8 patients with PID and 9 volunteers as controls performed a series of daily activities in their nature environment.They were monitored with IDEEA.Results The velocity of flexion forward,time flexion forward,time stand up,time sit down of the patients were significant different to the controls(P<0.05),and the walking speed of the former was slower(P<0.05)than the latter's.Conclusion Physical performance of the PID patients was significantly reduced.The IDEEA can be a good tool to evaluate their ability of locomotion in their daily living.
