The partial segment of Marek′s disease virus (MDV) glycoprotein B (gB) gene was amplified by PCR. The segment was cloned into pET-28a vector to obtain the recombinant pET-gB plasmid. The recombinant plasmid was transformed into E.coli BL21,and expressed in very high level as inclusion body after induced with 1.0mmol/L IPTG. The inclusion body was solubilized in urea (8mol/L) . The purified protein was obtained by use of His?Bind affinity chromatography. Mice were immunized i.p. by the purified protein to make the polyclonal antibody. The titer of the antibody by indirect ELISA was 1?10~ -5 . Moreover, the analysis by western blot proved that antibody was specific to the recombinant protein. These works lay a favorable foundation for the study of the immune response by MDV gB.

BACKGROUND:Recently, the biodegradable materials with good biocompatibility and with no adverse reaction have been widely applied in the clinical treatment and care of gynecology and obstetrics. The development of the biodegradable material is very rapid. OBJECTIVE:To summarize the application of biodegradable materials in gynecology and obstetrics. METHODS: The first author searched PubMed and CNKI databases for articles related to biodegradable materials in gynecology and obstetrics using the keywords of “degraded materials, biodegradable materials, gynecological care, surgery” in Chinese and English respectively. This article has an outlook of the potential application in gynecology and obstetrics based on clinical experience. RESULTS AND CONCLUSION:Biodegradable materials with good biocompatibility and biological security play an important role in biomedical materials. Their polymers and degradation products show smal adverse reactions to the body, and have good biomechanical properties, physical and chemical properties and good workability, which have been widely used in gynecology and obstetrics, such as absorbable stylolite and tampon tape. Although we have made a great progress on the biomaterial research, it stil has the limitation and safety flaws in the clinic. As the biomaterial research is further developed, the biomaterial application prospect wil be more promising.

AIM To explore the effects of trip-tolide on endothelin-1 and its gene expression in lung of asthmatic guinea-pigs. METHODS The contents of ET-1 in lung of asthmatic guinea-pigs were measured with radioimmunoassay, and the expressions of ET-1, ETA, ETB and ECEmRNA with reverse transcription DNA polymerase chain reaction (RT-PCR). RESULTS 0 All of the indexes were increased after guinea-pigs were induced asthma. At the 4th hour after first induction of asthma, ET-1 reached the top, but at the 2rd hour, ET-1mRNA, ETAmRNA and ECEmRNA were markedly higher than control group (P

The expressing cassette, LoxP-CMV-gpt-IRES-LoxP( about 2.9kb), was amplified by PCR from a plasmid, pIRES-gpt, by use of the primers , which contained the loxP sites in 5' terminals, respectively. The loxP sites were designed into primers by the software of Primer primer 5.0. Then the cassette was cloned into the site of BalI in pBUS10 to obtain pUS-gptIRES(L). The sequencing analysis for pUS-gptIRES(L) indicated that two loxP sites with the same direction were correctly inserted into pUS-gptIRES(L).The gpt gene in pUS-gptIRES(L) was replaced by a fragment including the full length GFP gene as well as SV40 poly A sequence to get pUS-GFPIRES(L). pUS-GFPIRES(L) was transiently transfected into CHO cell lines, and then the green fluorescence could be seen, the results showed that GFP gene could be expressed correctly. Moreover, pUS-GFPIRES(L) was transfected into the CEF infected MDV CVI988 strain and recombinant virus was selected by the green fluorescence. The growth curve of virus showed the characteristic of recombinant virus was the same as that of CVI988 in vitro. These results give the basis for further studying the characteristic of MDV in vivo and the application of the Cre/LoxP system to MDV genome.

BACKGROUND: Studies have shown that osteoporosis often leads to a failure in pedicle screw fixation. Considering that the use of ordinary pedicle screw fixation cannot achieve a strong and stable fixation of the osteoporotic vertebra,special measures to strengthen the internal fixation is indispensable.OBJECTIVE: To evaluate the effect of bone cement augmentation combined with expandable pedicle screw fixation on the fixation strength of osteoporotic thoracolumbar vertebrae.METHODS: Twenty osteoporotic thoracolumbar vertebral specimens were randomly divided into four groups: conventional pedicle screw group implanted with normal pedicle screw, and the other three groups implanted with expandable pedicle screw. Bone cement augmentation with polymethylmethacrylate (PMMA) and calcium sulfate was done in the PMMA group and calcium sulfate group, respectively, followed by expandable pedicle screw implantation. No bone cement was used in the expandable pedicle screw group. The maximum axial pull-out strength and yield energy absorption value of the unilateral pedicle were detected, and the maximum removal torque of the contralateral pedicle was determined. Bone cement leakage after augmentation was observed.RESULTS AND CONCLUSION: Compared with the conventional pedicle screw group, the other three groups showed a significant increase in the maximum pull-out strength, maximum removal torque and yield energy absorption values (P < 0.05). Moreover, these parameters were significantly higher in the PMMA and calcium sulfate groups than the expandable pedicle screw group and conventional pedicle screw group (P < 0.05), but there was no significant difference between the PMMA and calcium sulfate groups (P > 0.05). No leakage of bone cement was found in all the groups. To conclude, the combined use of expandable pedicle screw and can significantly enhance the stability of the osteoporotic thoracolumbar vertebrae, and the PMMA and calcium sulfate cements have similar effects.
