Objective To evaluate the gene therapeutic effects of guinea pigs model with immune -mediated inner ear disease(IMIED)after locally injection of bone -marrow mesenchymal stem cells(BMSCs) decorated by in-terleukin-4 gene .Methods Guinea pigs were immunized with keyhole limpet hemocyanin (KLH) and caused 55 animal models ,divided into five groups ,each group with 11 animals :groupA(BMSCs carrier) ,group B(BMSCs emp-ty -carrier control group) ,group C(recombinent lentivirus IL -4 gene) ,group D(lentivirus empty -carrier control group) ,group E(simulation operation control group) .Groups were all injected with the corresponding suspension (20 μl)[includs BMSCs ceas of (1 .5~2 .0) × 106 ,the concentration of (entivirus) is 0 .5 × 108 pfu] by the scala tympani window into the inner ear .The fluorography immunohistochemistry test and enzyme immunohistochemistry test for the situation of IL -4 gene express and productive protein distribution in inner ear .Auditory functions and the KLH level of guinea pigs blood were monitored respectively by auditory brainstem responses (ABRs) and ELISA test .Results The threshold of ABR wave Ⅲ decreased in group A ,group B and group C .The result were more significant in group A and group B than that in group C ,but results in group A was more prominent (P<0 .05) . The results of immunohistochemistry test showed that fluorescence positive BMSCs mainly scattered in scala tymani and scala vestibule .The microscope results showed that for the group A ,B and C ,there were only few foccule and red and white blood cells in scala tympani floc ,but for group D and group E ,with different levels of labyrinthine hy-drops and some mononuclear cells around the spiral ganglion and small blood vessels .Conclusion Restructuring lentiviral vector with IL -4 gene can be successfully transfected into BMSCs in vitro ,compared to inplangting into inner ear in scala tympani approach ,the cells can migrate and generate gene product of IL -4 ,to significantly im-prove the auditory functions and inflammatory reaction of inner ear disease ,and BMSCs can be used as a carrier to migrate to the damaged part with therapeutic gene .

OBJECTIVE:
To assess the effect of one-stage repair of secondary nasolabial deformity and nasal septoplasty for cleft patients on nasal airway resistance (NAR).
METHOD:
Using active anterior rhinomanometry, NAR was measured in eighteen patients with cleft lip and palate who suffered form one-stage repair of secondary nasolabial deformity and septoplasty at per-and-post operation.
RESULT:
NAR was (0.664 +/- 0.200) kPa/(s x L) before operation, (0.304 +/- 0.180) kPa/(s x L) six months after operation, and (0.396 +/- 0.250) kPa/(s x L) twelve months after operation respectively. The differences are statistically significant (P < 0.01) between the NAR before and after operation. Subjective impression score of nasal patency was 7.5 +/- 1.5 before-operation, 2.1 +/- 2.0 after-operation for six months, 3.0 +/- 2.4 after-operation for twelve months. There are significant differences in the subjective impression score of nasal patency as well (P < 0.01).
CONCLUSION
Correction of septal deformities play a very important role in the operation for secondary nasolabial deformity, which can decrease NAR and improve the subjective impression of nasal patency.

Objective To observe and compare the efficacy and safety between propofol-fentanyl and propo- fol-ketamine for anesthesia of artificial abortion.Methods 450 ASA physical statusⅠandⅡpatients scheduled for elective artificial abortion were randomized into three groups:P group were given intravenous normal saline 2ml be- fore propofol(n=150) ;PF group were given intravenous fentanyl 1?g/kg then propofol(n=150);PK group were given intravenous ketamine 0.4mg/kg then propofol(n=150).Total dose of propofol,extinction time of lash reflex, heart rate(HR),mean arterial pressure(MAP),pulse oxygen saturation(SpO_2),time to open the eye when called, time of full recovery(answering correctly and walking unaided),discomfort,awareness during operation,self-feeling were recorded.Analysis of date was with SPSS 12.0.P<0.05 was considered significant.Results No episodes of nausea,vomiting,cardio-cerebral syndrome or awareness were noted in all patients;Total dose of propofol,and extinc- tion time of lash reflex in P group were significantly more than those in PK or PF group(P<0.05),but there was no difference between PK and PF group;MAP,minimum HR and SpO_2 during operation were obviously lower than preoperation or postoperation in those in P or PF group,minimum HR and SpO_2 during operation in P group were significantly lower than in PF or PK group;Minimum HR and SpO_2 during operation in PK group were lower than preoperation,but its decrease extent was less than that in P or PF group(P<0.05);Time to eye opening in PF or PK group was significantly less than that in P group(P<0.05);Time to full recovery were not different in three groups;Incidence of pain on injection in PF group(10%)or PK group(8%)was obviously lower than P group (80%);Incidence of coughing and moving during operation in PF group(8%)or PK group(6%)was obviously less than P group(30%);No difference were noted with respect to degree of comfort,time of full recovery,bleeding vol- ume during operation,time to operation.Conclusion Painless artificial abortion can be preformed effectively and safely with propofol-fentanyl or propofol-ketamine,propofol-ketamine especially fits for painless artificial abortion compared with propofol-fantanyl.

OBJECTIVE:
To explore the therapeutic methods and effect of pingyangmycin injection in huge hemangioma at Hypopharynx and laryngeal under suspension laryngoscopy.
METHOD:
To ananysize the medical records of 12 Patients with giant hemangioma at hypopharynx and laryngeal. Patients were underwent polysomnography before operation. Inseted the suspension laryngoscopy to pars laryngea by mouth to exposing the hemangioma under general anaesthesia, then injected Pingyangmycin by a long-tube needling (one time per three weeks, accumulated dose less than 50 mg).
RESULT:
Among all patients, ten were cured and two showed obvious improvement. The data of PSG after operation indicates that the symptom of anoxia of post-operation were significantly ameliorated than that of pre-operation, no recurrence occurred during one year follow-up of the hemangioma.
CONCLUSION
The methods of pingyangmycin injection under suspension laryngoscopic surgery is significantly enhanced clinical effect and improved the life quality of patients with huge hemangioma, which with low risk, high security, can ameliorating anoxia, complete cure, and is a ideal therapeutic measure.
