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.

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.

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.
