Objective To study how polyclonal antibodies against ciliary neurotrophic factor (CNTF) reduce botulinum toxin-in- duced axonal sprouting and affect paralytic muscle.Design Experimental study.Participants 20 New Zealand rabbits.Methods In 10 rabbits randomly selected,left superior rectus were as control (Group 1),right superior rectus were injected with botulinum toxin A (BTXA) 2.5U (Group 3).At 14th day,bilateral superior recti were taken out under general anaesthesia.In the other 10 rabbits,left su- perior recti were injected equivalent physical saline (NS) as control (Group 2);right superior recti were injected with BTXA 2.5U,after 4 days,injected with 50?l polyclonal antibodies against CNTF at same site (Group 4).And at 14th day,bilateral superior recti were taken out for electron microscopy,dyed with acetylcholinesterase,argentums (Ag) to show nerve axonal sprout,and accounted and mea- sured with Leica microsystems.Main Outcome Measures The mean number of sprouts and the mean total length of sprouts,and the uhrastructure change of muscle by electron microscopy.Results In Group 1,the mean number of sprouts and the mean total length of sprouts were 5.75% and 10.53?m respectively;Group 2 were 6.11% and 11.16?m;Group 3 were 84.04% and 170.71?m;and Group 4 were 54.77% and 68.12?m.The differences were statistically significant (all P=0.000).Electron microscopy showed that after admin- istration BTXA alone (Group 3),muscle atrophied obviously,nerve myelin sheath increased,while the structure of nerve and muscle re- main invariable.The Group 4 showed that local myofilament disrupted and dissolved,degenerative myocytes necrotized and disintegrat- ed into fragments,which led to partial unreversible destroy.Conclusion Polyclonal anti-CNTF can reduce BTXA-induced axonal sprout- ing,lead to partial unreversible destroy of muscle,which may prolong the time of paralytic muscle resuming.It suggests that polyclonal anti-CNTF could prolong the duration of muscle paralyses induced by botulinum toxin.
3.Clinical effects of using rigid gas permeable contact lens for refractoriness amblyopia
International Eye Science 2014;(7):1337-1339
AlM:To explore the clinical effects of using rigid gas permeable contact lens ( RGP ) for refractoriness amblyopia patients.
METHODS: Ninety - eight cases ( 98 eyes ) were voluntarily divided into RGP group and frame glasses group, and the two groups were received the regularity combined training to treat amblyopia for 6mo. We overviewed the corrected vision (on that day, 1, 3, 6mo) and the complication in RGP group .
RESULTS: The corrected vision in RGP group was obviously better than that in control group during the same time. The therapeutic efficacy in RGP group was better than that in frame glasses group, without serious complications at 6mo after treatment.
CONCLUSlON: RGP groups could get better corrected visual acuity. lt is safe and effective to improve corrected vision for refractoriness amblyopia patients.

Objective:To prepare the canine multivalence serum for emergent prevation and theatmentor canines infection disease.Methods:Selecting 20 healthy Kunming dog,which is more than one years old.The canines were immuned by regulary with Canine distemper virus(CDV),Canine parvovirus virus(CPV),Infectious canine hepatitis virus(ICHV),Canine coronavirus(CCV),Canine parainflu-enza virus(CPIV).The blood were draw in freedom germ from neck's artery at canines and then blood was centrifugate for isolating serum.To check antibody's tite, micro serum neutrolization(SN) and hemagglutination inhibition(HI) were used.Results:Canine multivalence serum is successfully preparation and good curative effects in clinic.Conclusion:Canine multivalence serum may be of great value in economics and society and contribute to curative disease.

8.Therapeutic effects of focused ultrasound on chronic cervicitis and the influencing factors
Chinese Journal of Obstetrics and Gynecology 2001;0(01):-
Objective To explore the therapeutic effect of focused ultrasound(FU)on chronic cervicitis unitarily and its influential factors.Methods Three hundred and thirteen patients of chronic cervicitis were treated with the device of CZF model focused ultrasound.The therapeutic effects in 300 cases with complete records,as well as the relationship between the diameter of cervical erosion and the exposure time to FU were analyzed.Results The effective rates of FU in treatment of chronic cervicitis unitarily were 100.0%(53/53),95.2%(120/126)and 91.7%(111/121),respectively,for mild,moderate and severe cases.The overall effective rate was 94.7%(284/300).With other parameters of FU unchanged,the exposure time to FU showed an exponential relationship with the diameter of erosion,and the regression equation was D=31.71e~(0.4808t)(R~2=0.9966).Conclusions The controllability and achievement ratio of FU to treat cervical erosion could be enhanced when exposure time and manners were fully considered based on the diameter and type of cervical erosion.A satisfactory therapeutic efficacy could be achieved with FU to treat cervical erosion unitarily.
9.Advances in Studying Water Microbial Ecology by Molecular Biological Techniques
Microbiology 1992;0(04):-
Microbes are important composition of ecology system. Nowadays it's very important to study the microbial diversity and community structure, especially in water bioremediation by microbiological resources. Modern molecular biology techniques provide effective methods to study the microbial ecosystem in aqua. Several techniques were summarized, including 16S rDNA clone library, DGGE (Denaturing gradient gel electrophoresis), RFLP (Restriction Fragment Length Polymorphism) and T-RFLP (Terminal Restriction Fragment Length Polymorphism), while their application to analyze water microbial diversity were introduced.
10.Her-2/neu gene and radiosensitivity
China Oncology 2006;0(11):-
Her-2 receptor has already been identified as one of the most important biological markers of some malignant tumors,and also plays an important role in the biological behavior of those tumor cells.The over-expression of Her-2 receptor is associated with radioresistance of various tumor cells,and thus an antibody to Her-2/neu receptor can probably function as a radiosensitizer.In this review,we summarized some advances in the molecular mechanism and clinical aspects of the relationship between Her-2 and cellular radiosensitivity.
