2.Expression of VP2 Gene of Feline Panleukopenia Virus Isolated from Tiger in Pichia pastoris Yeast
Microbiology 1992;0(01):-
In this study,the VP2 gene of feline panleukopenia virus(FPV) isolated from tiger was successfully cloned and expressed in Pichia pastoris yeast.The VP2 gene was amplified by PCR with a pair of specific primer.Then PCR products was purified and cloned into pGEM-T for sequencing.The interesting gene fragment was recovered after the double enzyme digestion of EcoRI/NotI,then subcloned into pPICZ?A for secretory expression.The recombinant pPICZ?AVP2 was linearized with SacI and then transformed into competence yeast GS115 for expression under the induction of 1% methanol.The positive recombinants were screened by PCR method.The expression product was identified by SDS-PAGE and western-blotting.The results showed that there was a molecular weight of 32 kD,which could be specifically recognized by polyclonic antibody against FPV.It revealed that the recombinant VP2 protein had correct three-dimensional structure,which would be used as a antigen protein for the diagnosis and prevention of FPV infection in tigers.
3.Varicella
Chinese Journal of Vaccines and Immunization 2008;0(01):-
Varicella is an acute,highly contagious respiratory and caused by Varicella-zoster virus(VZV),After the primary infection,VZV induce Varicella,then the virus remains dormant in sensory nerve roots in life.Upon the reactivation,shingles can occur.Most of patients can recovery very soon,but kinds of potentially sever complication can induce death.Nowadays the VZV vaccination isn’t included in the expanded immunization program in our country. Varicella outbreaks take place at times in the middle of children of our country.The paper offers concise description about pathogen characteristics,diagnosis methods,clinical character,epidemiology knowledge and strategy of prevention.
4.Application of induced pluripotent stem cells in retinal diseases
Recent Advances in Ophthalmology 2017;37(6):587-590
Induced pluripotent stem cells (iPSCs) are a type of pluripotent stem cells that can be generated from adult somatic cells.They have similar characteristics and function to embryonic stem cells (ESCs).Over the past decade,iPSCs were widely concerned in regenerative medicine and stem cell field.Especially the patient specific iPSCs have several advantages over ESCs,such as convenient source,do not exist immune rejection and ethical issues,even keep certain individual genotype.At present,tremendous progress have been made about the application of iPSCs in a variety of retinal diseases.Here,this article reviews pluripotent stem cell sources of RPE,photoreceptors and retinal ganglion cells and current transplantation strategies,the safety problems and prospects.
5.The progress of bone morphogenetic protein on the mechanism of osteoblast cell differentiation
Journal of Medical Postgraduates 2003;0(05):-
Bone morphogenetic protein is a key regulation factor in osteoplast cell differentiation and bone formation.It takes a role of differentiation inducting and orientating by modulating the transcription factor and through some unknown signal transduction pathway,and its expression and function can be adjusted by signal transducting system and specific acceptor inhibiter.This article reviews the research progresses on the aspects.
6.EFFECTS OF HIGH FREQUENCY JET VENTILATION ON RESUSCITATION OF BRAIN FUNCTIONAL FAILURE IN CATS
Medical Journal of Chinese People's Liberation Army 1981;0(04):-
The effects of high frequency jet ventilation(HFJV) on brain resuscitation had been investigated in 28 cats in which simple brain functional failure was produced by occlusion of both carotid and both vertebral arteries. The results suggested that HFJV could improve endurance of cats when subjected to brain ischemia, raise the survival rate of cats with reversible brain functional failure, and prolong the survival time of cats with permernent brain functional failure. The mechanisms of how HFJ would exert beneficial effect on brain resuscitation was discussed.

Objective To investigate the expression changes of hepatic gelsolin (GSN) and the potential effect of traditional Chinese medicine Xuebijing injection in septic rats. Methods A total of 104 male Wistar rats were randomly divided into four groups, ie, normal control group (n = 8), sham operation group (n = 32), cecal ligation and puncture group (CLP group, n = 32) and Xuebijing treatment group (n = 32). The sepsis animal models in the last two groups were developed by CLP. In Xuebijing treatment group, animals were treated intravenously with Xuebijing injection (4 ml/kg) at 2, 12, 24,36, 48 and 60 hours after operation, respectively. Animals were sacrificed respectively at 6, 12, 24, and 72 hours after operation to harvest blood and hepatic tissue samples. Markers of liver function, contents of GSN and Gc globulin and expression of GSN mRNA in the liver tissues were detected. Results Compared with normal control group and sham operation group, hepatic GSN content was decreased significantly at various intervals in CLP group (P < 0. 05), which reached the lowest value of (1.42 ±0.50) ng/mg at 12 hours. Meanwhile, expression of GSN mRNA in the liver was markedly enhanced at six hours after CLP and remained a high value until 72 hours, compared with the sham operation group (1.203±0.053 vs 1.030 ±0.084, P <0.05). Similarly, the hepatic Gc globulin contents was increased in the CLP group compared with the normal control group and sham operation group (P < 0.05).After treatment with Xuebijing injection, the hepatic GSN contents at 6-72 hours was increased gradually while serum ALT and AST levels at 6, 12 and 24 hours were reduced significantly in comparison to the CLP group (P < 0.05). Nevertheless, treatment with Xuebijing injection showed no marked effect on hepatic GSN mRNA expression and Gc globulin release (P > 0.05). Conclusions Hepatic GSN contents are persistently reduced in the development of sepsis and treatment with Xuebijing injection can markedly attenuate acute liver injury through increasing GSN contents in severe sepsis.

To establish the control model of medical insurance in hospitals, so as to improve the effectiveness of internal operation for medical insurance fund. Methods: Using the utility theory to establish the control model, with which the medical service provider is individual rationality constraints and incentive compatibility constraint. Results: The bonus coefficient and punishment coefficient can be calculated by means of evolutionary programming. Conclusion: The control model of hospital internal medical insurance fund is useful in controlling the medical insurance expense, it also provides the guidance and references for performance management and internal operation.

Objective To explore the effects of Taiji exercise on the psychology and the functions of the autonomic nervous systems of middle aged and elderly people. Methods Two hundred and seven middle aged and elderly Taiji exercisers and 166 age matched non Taiji exercisers were sampled. The Zung Self rating Anxiety Scale(SAS), Zung Self rating Depression Scale (SDS) and autonomic nervous system equilibrium index (ANSEI)were adopted to assess the subjects. Results Compared with those of the control group, the scores of SAS and SDS in Taiji group were significantly higher, and the equilibrium of autonomic nervous systems in Taiji group was also superior. There was no significant difference between the male and the female with regard to SAS, SDS and the equilibrium of autonomic nervous systems within Taiji group. The longer the exercise, the better the equilibrium of autonomic nervous systems. Conclusion Taiji exercise has positive effects on the psychology and the autonomic nervous system of the middle aged and the elderly.
