Optogenetics is a novel technique which combines optics with genetics.Using genetic means,a selected opsin protein is ectopically expressed in target neurons,which are then stimulated by light to moderate the neuronal circuit,as a consequence to regulate the animal's behaviors.Retinal degeneration like retinitis pigmentosa and aged macular degeneration causes visual impairment and eventual blindness.Optogenetics techniques have opened the door to creating artificial photoreceptors in the remaining retinal circuits of retinal degeneration retinas via gene therapy.However,there are still limitations in optogenetics technique,for example,potential risk in virus infection,the choice of target cells and the low visual resolution of the experiment animal.It has been reported that vision was successfully restored to a certain extent in animal model using optogenetics technique.With higher photosensitivity of opsin protein,longer activation kinetics and higher transfection efficiency of virus vector,optogenetics techniques' application in ophthalmology will be improved.

Purpose　The aim is to study α-glucosidase inhibitor from Schisandra Chinensis(Turcz.)Baill.Methods　The inhibitor was purified by soaking,ultrafiltration,ion-exchange chromatography and Lead Acetate deposition.Results　A α-glucosidase inhibitor was obtained.Conclusion　The inhibitor was a kind of non-competition inhibitor with large molecular weight of over 5×105D.

Objective To study the best parameters of low dose MSCT in examining the pharyngeal disease.Methods 20 volunteers were scanned by MSCT using 10 mm collimation,10 mm interval,120 kV,200 mA,100 mA,50 mA,25 mA parameters,respectively.All of the data was reformed(collimation 2.5 mm,interval 1.3 mm) on ADW 4.0 workstation.The image quality in different dose were scored respectively by 4 experienced radiolagists. Results The best appropriate parameter was 10 mm collimation,10 mm interval,120 kV,50 mA.Conclusion In examining the pharyngeal disease,the application of low dose(120 kV,50 mA) scan mode not only can assure the image quality but can decrease the exposure to patients.

OBJECTIVE: To create a rhinogenic model of acute sinusitis in the rabbits. METHOD: Thirty-two New Zealand white rabbits were divided into four groups: A group (nasal cavity-implanted with synthetic sponge), B group (nasal cavity-implanted with synthetic sponge and bacteria inoculation), C group (bacteria inoculation group), D group (control). The animals were examined by the methods of endoscope, histology and bacteriology after two weeks. RESULT: The success rate of model were 60% (A group), 100% (B group) and 0% (C,D group). Both maxillary sinus and ethmoid sinus had developed inflammation. CONCLUSION A rhinogenic model of acute sinusitis can be created by inserting synthetic sponge instilled with pathogenic bacteria into nasal cavity. This is a simple method and has the potential to be valuable to study on FESS.

Objective To investigate clinical effect of Miccoli surgical thyroid bilateral subtotal resection for Graves disease,to provide a reference for clinical treatment.Methods 80 patients with Graves disease were selected, they were divided into the observation group and the control group according to the surgical approach.44 patients in control group were taken small incision under direct vision routine bilateral subtotal thyroid treatment,36 patients in the observation group took Miccoli surgical.Surgical success rate,surgical index were compared between two groups. Results The patients of the two groups were operated smoothly,the success rate was 100.00% in the observation group,the incision length,blood loss,operative time were (3.04 ±0.64)cm,(32.25 ±3.29)mL,(81.19 ±6.68)min respectively,which were significantly less than those of the control group,the differences were statistically significant (t =5.214,P =0.004;t =14.514,P =0.000;t =6.514,P =0.001).The VAS score,length of stay,incidence rate of complication in the observation group were (1.93 ±0.43),(3.82 ±0.79)d,5.26%,which were significantly better than those in the control group,the differences were statistically significant (t =5.697,P =0.003;t =4.654,P =0.009;χ2 =11.214,P =0.000).The hospitalization cost of the observation group was (9 043.65 ±565.76)Yuan, which was significantly higher than the control group,the difference was statistically significant (P <0.05).The cut rating of the observation group was (8.35 ±2.15)points,which was significantly higher than the control group,the difference was statistically significant (t =8.364,P =0.001 ).The hyperthyroidism relapse during follow -up,the incidence of thyroid dysfunction between the two groups had no significant difference (χ2 =0.568,P =0.311;χ2 =0.604,P =0.294).Conclusion Miccoli improved surgical incision and under direct vision thyroid bilateral subtotal resection both have similar clinical effects for Graves disease,Miccoli surgery has smaller trauma,more satisfaction incision,but under direct vision small incisions has lower treatment costs.
