Objective To study the role of the chimeric hsp70/CD80 DNA vaccine for treatment for TB. Methods C57BL/6N mice challenged with H37Rv were immunized with the chimeric hsp70/CD80 DNA vaccine, hsp70 DNA vaccine and BCG in order to compare the therapeutic role of these vaccines. Results The levels of interferon ? (IFN-?) in the serum of mice in hsp70/CD80 group (1336.98?129.64) pg/ml was significantly higher than in group BCG (121.54?56.39) pg/ml, pcDNA3 (192.00?64.36) pg/ml and pcDNA3 hsp70 (542.33?99.77) pg/ml. The growth of Mycobacterium tuberculosis in live and spleen were inhibited significantly in hsp70/CD80 vaccinated mice. Conclusions The chimeric hsp70/CD80 DNA vaccine was more efficient than BCG and hsp70 DNA vaccine alone in treating TB.

Objective To explore the effects of ursodeoxycholic acid (UDCA) on the fluidity of rat visceral sac and placental glutathione (GSH) concentration in rats with intrahepatic cholestasis. Methods Sixty rats were randomly divided into 3 groups (20 in each). Refined vegetable oil 2.5 ml/(kg?d) was given to the control group since the 13 days of pregnancy. The ICP treatment and non treatment group received either progesterone 75 mg/(kg?d) or 17? ethynylestradiol 1.25 mg/ (kg?d) from the 13th to 17th day, respectively. From the 17th day, the control and non treatment group were fed with 0.9% nitrachloride solution 5 mg/(kg?d) and the treatment group with UDCA 50 mg/(kg?d). All rats were sacrificed on the 21st day. The visceral yolk sac cell membrane and GSH concentration were measured Results The concentration of GSH in the ICP non treatment group (1.12?0.02 mmol/g protein) was significantly lower than that of the treatmentgroup (1.38?0.03 mmol/g protein) and the control group (1.56?0.07 mmol/g protein) ( P 0.05). The fetal death rate in treatment group (9.55%) and control group (1.97%) was significantly lower than that of the non treatment group (20.47%) ( P

Objective To investigate the recent studies about the relationship between Chlamydia pneumoniae and abdominal aortic aneurysm. Methods The current literatures about the relationship between Chlamydia pneumoniae and abdominal aortic aneurysm were reviewed. Results Chlamydia pneumoniae is one of the most important factors for the formation of abdominal aortic aneurysm since Chlamydia pneumoniae can cause abdominal aortic aneurysm through the metabolism of matrix metalloproteinases, the apoptosis of smooth muscle cells in the vessels and the chronic infection of the wall of the aneurysm. Conclusion There maybe a distinguishingly close relationship between Chlamydia pneumoniae and abdominal aortic aneurysm, and Chlamydia pneumoiae may take an important role in the development and progress of the abdominal aortic aneurysm.

OBJECTIVE: A case of half sibling was determined with multiple genetic markers, which could be potentially applied for determination of half sibling relationship from same father. METHODS: Half sibling relationship was detected by 39 autosomal STR genetic markers, 23 Y-chromosomal STR genetic markers and 12 X -chromosomal STR genetic markers among ZHAO -1, ZHAO -2, ZHAO -3, ZHAO -4, and ZHAO-5. RESULTS: According to autosomal STR, Y-STR and X-STR genotyping results, it was determined that ZHAO-4 (alleged half sibling) was unrelated with ZHAO-1 and ZHAO-2; however, ZHAO-3 (alleged half sibling), ZHAO-5 (alleged half sibling) shared same genetic profile with ZHAO-1, and ZHAO-2 from same father. CONCLUSION It is reliable to use multiple genetic markers and family gene reconstruction to determine half sibling relationship from same father, but it is difficult to determination by calculating half sibling index with ITO and discriminant functions.

Objective To investigate the effect of HSP70/CD80 DNA vaccine on the airway inflammation and hyperresponsiveness of asthmatic mice. Methods Forty female healthy BALB/c mice were randomly divided into 4 groups; saline group, asthma group, pcDNA3. 1 plasmid control group, and prevention group with HSP70/CD80 DNA vaccine, with 10 mice in each group. The mice were immunized by intramuscular( i. m. ) injection with HSP70/CD80 DNA vaccine before sensitization and challenge with ovalbumin. Then, the murine model of allergic asthma was made with injection of ovalbumin intraperitoneal ( i. p. ) , and inhalation of ovalbumin. Before mice were sanctified, their airway hyperresponsiveness( AHR) was measured. After mice were sanctified, bronchoalveolar lavage fluid( BALF) was obtained and cytokine IL-13 and IFN-γ were measured. And the lung histology and histochemistry were examined. Results Compared with mice in asthma and pcDNA3. 1 group, mice in vaccine group showed significantly reduced airway inflammation (P＜0. 05) and AHR (P＜0. 05). IFN-γ content in BALF were increased in mice from vaccine group compared with the asthma group and the pcDNA3. 1 group ( P ＜0. 05) , and IL-13 content in BALF were decreased. Conclusion HSF70/CD80 DNA vaccine can reduce airway inflammation and hyperresponsiveness in asthmatic mouse and this chimerical plasmid could be a candidate vaccine to prevent asthma.

Objective To investigate the significance and mechanism of intracerebroventricular injection viper venom nerve growth factor (Vngf) in rat neural plasticity after cerebral ischemia reperfusion injury.Methods Ninety Wistar male rats were randomly assigned into Vngf-25 U group (n = 18), Vngf-50 U group (n = 18), Vngf-100 U group (n = 18), ischemia reperfusion group (n = 18) and sham operated group.The expression of candidate plasticity-related gene 15(cpg-15) Mrna and nuclear factor of kappa B ( NF-Κb ) Mrna in rat brain tissues which were collection at 2,7,14 days after surgery were evaluated by the real time PCR.Results The expression of cpg-15 Mrna and NF-Κb Mrna began to increase after surgery( the F value of cpg-15:70.43, 34.11, 31.89, the F value of NF-Κb: 27.47, 34.56, 31.89,P＜0.01).At the same time, expression of cpg-15 Mrna and NF-Κb Mrna in the Vngf groups was significantly different from the I/R group and the sham operated group (the F value of cpg-15:48.18, 55.93, 78.43, the F value of NF-Κb: 45.92, 55.72, 50.49, P ＜0.01).The more Vngf were injected, the more cpg-15 Mrna and NF-Κb Mrna were expressed in Vngf groups.Conclusions The Vngf could accelerate neural plasticity and restore neurofunctional defect through up-regulated the expression of cpg-15 and NF-Κb.

BACKGROUND: Angiogenesis attracts much attention in tissue engineering field. Previous research has proved that a two-dimensional culture of vascular endothelial growth factor (VEGF) promotes angiogenesis.OBJECTIVE: To evaluate the effect of VEGF on three-dimensional angiogenesis.METHODS: Endothelial progenitor cells were separated from the SD rat bone marrow. At about 70%-80% fusion, rat tail collagen gel was added to establish three-dimensional models. Samples in the experimental group were incubated in complete culture solution containing M199 culture media, fetal bovine serum, VEGF, and double antibody. The samples in the control group were incubated with VEGF-free culture media. In vitro culture and amplification of bone marrow-derived endothelial progenitor cells were determined at 1, 4, 7, and-20 days after incubation. Morphology and quantitative analysis were performed at 3, 6, 9, and 12 days after three-dimensional model establishment.RESULTS AND CONCLUSION: Endothelial progenitor cells grew from three-dimensional matrix into collagen matrix in the experimental group. Budding and infiltration were observed in the collagen within 24 hours, and branching-like structure was then gradually formed. Cells in the control group grew slowly, with slowing budding, small tubiform structure, superficial infiltration into COllagen, sparse network structure, and non-intact. Numbers of newborn vessels in the expedmental group were significantly greater than control group (P<0.01). A detection on gel block showed positive expressions of endothelin-1 and endothelial nitric oxide synthase-3 on the 3~(rd), 6~(th), 9~(th), and 12~(th) days. The results demonstrated that VEGF mobilized and induced endothelial progenitor cells in order to promote angiogenesis. Rat tail collagen gel induced endothelial progenitor cells which behaved migration, proliferation, and pullulation of angiogenesis.
