AIM: To evaluate the clinical efficacy of surgery for spontaneous subconjunctival orbital fat prolapse via bulbar conjunctiva under topical anesthesia.
●METHODS: A total of 22 eyes of 11 patients received surgery for spontaneous subconjunctival orbital fat prolapse via bulbar conjunctiva under topical anesthesia were included. Objective and subjective duration of the operation, degree of cooperation during surgery, postoperative recovery, recurrence and complications were observed.
●RESULTS: In the process of surgery, patients without pain and being-cooperated were recorded in 17 eyes. The patients who occasionally felt slight pain, but within endurance after adding topical anesthesia once and the operation was completed successfully were recorded in 5 eyes ( the second eye surgery ) . The operation was successfully completed in all the patients. Compared the coordination degree during surgery of Gradel with GradeⅡ, the difference was statistically significant ( t=-3. 123, P<0. 01). All eyes were healed well after operation.
● CONCLUSION: The surgery for spontaneous subconjunctival orbital fat prolapse via bulbar conjunctiva under topical anesthesia can ensure satisfactory anesthetic effect and get better quality of operation. It′s a simple, safe and effective anesthesia method for spontaneous subconjunctival orbital fat prolapse.

Objective To study the correlations between bone fracture types and healing time in patients with osteofluorosis. Methods Thirty-seven patients with osteefluorosis and long tubular bone fracture were diagnosed in accordance with radiogram retrospectively. The fractures were divided into two groups: sclerotic and osteoporotic. Twenty four fractured patients with non osteofluorosis were included in the study as controls. All of the patients had operation(open reduction and nickelclad internal fixation). Fracture healing in patients with sclerotic and osteoporotic groups was compared with the control group after operation. Results There were notable differenees(F=4.30,P< 0.05) in term of fracture healing time among the three groups [sclerotic group:(18.4±5.3)weeks; osteoporotic group: (24.5±5.1)weeks; control group: (17.6±3.8)weeks]. Notably, there were significant differences between the osteoporotic and control groups(q=2.34,P<0.05), and between sclerotic and osteoporotic gronps(q=2.51, P<0.05). The healing time of the osteoporotic group was longer than that of sclerotic group. The constituent ratios of fracture healing in sclerotic, osteoporotic and control groups were 73.1% (19/26) ,54.5% (6/11),75.0% (18/24) respectively, and the differences among the three groups were statistically significant(X2=3.67,P<0.05). The healing rate of the osteoporotic group was lower than that of sclerotic and control groups(X2=3.12, 3.36, all P< 0.05). The constituent ratios of healing in the sclerotic, osteoporotic and control groups were 26.9% (7/26),45.5% (5/11),25.0%(6/24), respectively, and there differences among the three groups were statistically significant (X2=4.07 ,P<0.05). The delayed healing rate of the osteoperotic group was higher than those of the sclerotic and control groups(X2= 3.87,3.95, all P<0.05). Conclusions Fracture healing time of osteoporotic osteofluorosis after fracture is longer than normal, and the cause might be the loss of bone mass.

Objective To provide the service for scientific innovation and competition in biomedical industry of Hunan Province and the reference for working out biomedical patent strategies.Methods The data of biomedical patents in Hunan Province were collected using the patentEX and processed by metrics.Results The application number of patents increased from year to year with a high expiry rate.The technology of biomedical patents has entered into its mature period and the application of patents was focused on several important IPC classifications.Conclusion Tra-ditional technologies play a main role in biomedical industry of Hunan Province, but Hunan Province is relatively backward in modern biological technologies.The application number of invented biomedical patents is rather large, but their overall academic level is rather low.The majority of biomedical industry enterprises lack of competition awareness.It is thus necessary to strengthen the development of modern biological technologies, improve the aca-demic level of biomedical patents, increase the competition awareness of biomedical industry enterprises, lay stress on cooperative development of biomedical patents and on support of biomedical industry enterprises.

Objective To investigate the clinical efficacy of intravitreal injection of Lucentis combined with pan retinal photocoagulation and trabeculectomy for neovascular glaucoma(NVG). Methods Seventeen eyes of 15 patients with NVG were treated by 0.5 mg Lucentis intravitreal injection first. Trabeculectomy was performed 7 days later and Pan retinal photocoagulation 2 weeks later. Iris,anterior chamber angle neovascularization,intraocu?lar pressure ,and visual acuity were observed in the following 6 months. Results Iris and anterior chamber angle neovascularization were completely regressed 7 days after the injection in 17 eyes. Six months after photocoagulation, 6 eyes had different degrees of improvement in visual acuity,10 eyes no change in visual acuity and 1 eye decreased from anterior index to immediate manual. There was significant difference in pre?treatment IOP and postoperative IOP( t = 12.75 ,10.26 ,9.73 ,10.77 ,P < 0.01 ). No serious complications were observed after intravitreal injec?tion and trabeculectomy. Conclusions Intravitreal injection of Lucentis could significantly accelerate the regres?sion of iris and anterior chamber angle neovascularization ,which could improve the successful rate of trabeculecto?my and pan retinal photocoagulation. Intravitreal injection of Lucentis combined with trabeculectomy and panretinal photocoagulation is safe and effective for NVG.

Objective To investigate susceptibility and antibacterial activity of cationic porphyfin derivative mediated photodynamic antimicrobial chemotherapy (CPD-PACT) against Pseudomonas aeruginosa,to provide experimental evidence for its high efficiency antibacterial activity.Methods The impacts of culture environments on minimum inhibitory concentration (MIC) were measured by double dilution method.The formation of inhibition zone was determined by diffusion plate method.The postantibiotic effect was analyzed by colony forming units.The viability and morphology of Pseudomonas aeruginosa were observed by confocal laser scanning microscopy (CLSM).Results The inoculum size of bacterial had a certain effect on the MIC.The MIC values increased as the pH of medium rose.When the calf serum content of culture medium increased,the MIC rose in light reaction and dropped in dark reaction.The diameter of inhibition zone mainly depended on the laser energy density,but not the concentration of photosensitizer.Though CPD possessed strong antimicrobial activity and persistent suppression on bacterial growth,the surviving Pseudomonas aeruginosa would soon continue to proliferate after PACT.The fluorescence images captured by CLSM showed that CPD-PACT could destroy the membrane integrity,leak the cytoplasmic component,decrease the bacterial activity and finally lead Pseudomonas aeruginosa to death.Conclusions CPD has strong inhibitory activity and obvious postantibiotic effect on Pseudomonas aeruginosa,which is suitable to be developed as an drug candidate for PACT.

GPS was used in the snail survey of Nuanhuping marshland in Poyang Lake region and its application value was discussed. The results suggest that GPS which can measure the marshland area and survey area at real-time and draw electronic maps of snail situation rapidly, could realize the electronic and image management of the data from snail survey and provide more accurate information to the department in charge of schistosomiasis control.

Objective To explore the epidemical pattern of acute schistosomiasis in Poyang Lake area so as to provide the scientific evidence for control-strategy-making. Methods The data of acute schistosomiasis in 12 counties along Poyang Lake from 1960 to 2007, including the data of 2 special investigations from 1982 to 1984 and from 1987 to 1989 were collected and analyzed with the retrospective investigation methods. Results There were 29 864 cases of acute schistosomiasis in 12 counties of Poyang Lake area from 1960 to 2007, accounting for 85.5% of the total acute schistosomiasis cases of Jiangxi Province. The largest number of cases existed in Yugan County, accounting for 18. 7%. The peak of acute schistosomiasis prevalence was in 1987 with 2 088 cases. However, the case of acute schistosomiasis declined significantly, keeping at a low level, since 1990. During the 2 special investigations, the people whose age were lower than 30 years old, were the susceptible populations of acute schistosomiasis (86. 1% and 82. 9% , respectively) , most of them were peasants and students, and the infection rates were 57. 4% and 21.2%, 61.7% and 21. 8%, respectively. Fishing and swimming were the main infection ways, with the infection rates of 43.0% and 44.9% , respectively. The peak season of infection was from April to October. Conclusions The river bank and continent of Poyang Lake are the main infection areas, the spring and autumn are the main epidemic seasons and the susceptible populations are the peasants, fishmen and young students. It is very important to enhance the comprehensive prevention and treatment measures in the key areas and population for schistosomiasis control.
