Objective To investigate the therapeutic effect of paclitaxel plus oxaliplatin chemotherapy to the transplanted non-small cell lung cancer of nude mice and the effect to the apoptosis protein expression of PDCD5 and XIAP with mice model.Methods A tumor-bearing mice were randomly divided into blank group, normal saline group, oxaliplatin group, paclitaxel group, paclitaxel plus oxaliplatin group.The gene expression of PDCD5 and XIAP was assayed by real-time quantitative PCR(q-PCR).The apoptosis related PDCD5 and XIAP protein were detected by Western blot.Finally, the tumor weight of each group was measured for statistical analysis.ResultsThe mRNA expression of PDCD5 was highest and the gene expression of XIAP was lowest in paclitaxel plus oxaliplatin group(P<0.01).The expression of PDCD5 protein was highest and the expression of XIAP protein was lowest in paclitaxel plus oxaliplatin group (P<0.01).Finally, compare the tumor weight of each group, paclitaxel plus oxaliplatin group has the least mass(P<0.01).Conclusions Paclitaxel plus oxaliplatin group chemotherapy significantly increases PDCD5 expression and reduce XIAP expression.Meanwhile, paclitaxel plus oxaliplatin chemotherapy can significantly reduce the tumor weight of happened non-small cell lung cancer.

Objective: To investigate the effect and mechanism of liraglutide on vasodilatation of thoracic aortic ring in experimental rats.
Methods: The thoracic aortic rings were isolated from 32 male SD rats and divided into 2 groups: Without endothelium group and With intact endothelium group, n=16 in each group. The contractile force of vascular ring was detected and the effect of liraglutide (1×10-5 mol/L) on vasodilatation of norepinephrine (NE, 1×10-6 mol/L) pre-contracted ring was observed. The aortic ring in With intact endothelium group was further divided into 2 sub-groups:①the aortic ring was pre-treated by the inhibitor of nitric oxide synthase (NOS) (L-NAME at 10-4 mol/L),② the aortic ring was pre-treated by non-specific ATP-sensitive-potassium (KATP) channel (Glibenclamide at 10-5 mol/L), n=8 in each group. The impacts of liraglutide on those 2 sub-groups were studied.
Results: Liraglutide had no effect on isolated aortic ring at basic condition. Liraglutide at (10-5 mol/L) had vasodilatation effect in both Without endothelium and With intact endothelium groups, the effect was stronger in With intact endothelium group and the maximum vasodilatation reached 17%, P<0.05. In both pre-treated sub-groups, the effect of liraglutide on vasodilatation in sub-group①reached 4%, P<0.05, and the effect in sub-group②
reached 14%, P>0.05.
Conclusion: Liraglutide had obvious effect of vasodilatation on NE pre-contracted thoracic aortic ring in experimental rats, the mechanism might be related to NOS, while KATP channel could not block the vasodilatation effect of liraglutide.

Objective To evaluate the blood-saving effect of tranexamic acid in elderly patients undergoing total hip replacement.Methods One hundred and sixty ASA Ⅱ or Ⅲ patientss of both sexes,aged 65-70 yr,with a body mass index of 16-22kg/m2,undergoing total hip replacement,were randomly divided into 2 groups(n =80,each):control group(group C)and tranexamic acid group(group T).Anesthesia was induced with midazolam,fentanyl,etomidate and atracurium.The patients were tracheal intubated and mechanically ventilated.PEr CO2 was maintained at 35-45 mm Hg.Aneslhesia was maintained with propofol,remifentanil and atracurium.Before the skin incision,tranexamic acid 15 mg/kg was infused over 15 m in in group T,while the equal volume of normal saline was given instead in group C.Hemoglobin(Hb),platelet count(PLT),prothrombin time(PT),and activated partial thromboplastin time(APTT)were monitored during operation to guide blood transfusion.Intraoperative and postoperative blood loss and allogeneic blood transfusion were recorded.Postoperative complications were also recorded.Results There was no significant difference in the amount of intraoperative blood loss between the two groups(P ＞ 0.05).The amount of postoperative blood loss was significantly smaller and less allogeneic red blood cell was transfused in group T than in group C(P ＜ 0.05).No complications occurred after operation in either group.Conchusion Tranexamic acid has blood-saving effect in elderly patients undergoing total hip replacement,but the clinical value is limited.

Objective To assess the clinical feasibility and safety of coronary artery angiography(CAG) and intervention through transradial approach. Methods 134 patients received coronary artery angiography and interventions through transradial approach were selected. The complications such as hematoma, thrombus were observed. Results Transradial puncture succeed in 126 cases, the successful rate of transradial coronary intervention was 94.0%.The complication occurred in 12 patients (8.9%). Conclusion This investigation demonstrated the safety and feasibility of transradial approach for coronary angiography with less procedure complications and pain for patient.

0.05) The infarct volume in control group was significantly larger than that in I-15 s and I-30 s groups. There was no significant difference in the brain infarct volume between I-15 s and I-30 s groups. Conclusion Ischemic postconditioning attenustes the brain injury induced by focal cerebral ischemia and reperfusion.

A strain of canine parvovirus (CPV) was isolated from feces of an ill puppy in an animal hospital in Wuhan, China. It was designated as CPV/WH02/06. This isolate was identified as serotype CPV-2a by the hemagglutination test, CPV Ag detection strip, electron microscopy, and PCR. The vp2 gene was cloned and sequenced and assigned GenBank accession number EU377537. A 1242 bp segment of the 5' region of the vp2 gene was cloned and inserted into the binary vector pBI121 and used for Agrobacterium-mediated tobacco transformation. Transgenic tobacco plants were selected on MS medium supplemented with 100 μg/mL kanamycin and 100 μg/mL timentin. Integration of the vp2 gene into the tobacco genome was confirmed by PCR using T1 progeny plants, and the expression of the VP2 protein was confirmed by Western blotting.

OBJECTIVE: To analyze the relationship of the height difference and bone density (BD) of premenopausal and postmenopausal women. METHODS: The height values of 191 premenopausal and postmenopausal women were recorded, and the BD values of lumbar vertebrae and hip were detected by double energy X-ray BD detector. RESULTS: The lower the height of the postmenopausal women, the less the BD value. The BD of lumbar vertebrae dropped 0.025 5 g/cm(2) with each 2 cm of the shortened height, and the BD of hip joint dropped 0.029 2 g/cm(2). The shortened value in postmenopausal women with osteoporosis was statistically greater than that in postmenopausal women without osteoporosis. CONCLUSION: The BD of the postmenopausal women can be estimated by the calculation of their shortened height value.

Objective To investigate the survival profile of the intradermally injected mouse autologous skin fibroblasts and the changes of the collagen fibers by using green fluorescent protein labeling and two-photon fluorescence microscopy. Methods The cultured cells were transfected by EGFP lentivirus, and then the cells were injected into the corresponding mouse skin. Biopsy was taken from the animals after 1 and 2 months. The specimens made serial frozen sections, the survival profile of the injected cells and the changes of the collagen fibers were observed by two-photon fluorescence microscopy. The collagenic area and dermal thickness were measured with image analysis software, and statistical analysis was also carried out. Results Two-photon fluorescence microscopy showed clear images of the injected cells and collagen fibers. Both the area of collagen fibers and the dermal thickness were significantly increased in injected cells after 2 months (P<0.05), however, there were no difference between injected cells and control after 1 mouth (P>0.05). Conclusions Autologous cultured fibroblasts could survive in a long time after transplantating into the skin, and collagen could be newly produced, the depth of dermis increases, which provides a possibility to treat mini-defects of the tissue.
