Objective To understand the schistosomiasis prevention knowledge of middle school students from areas with dif-ferent endemic levels in Hubei Province. Methods The schistosomiasis endemic regions were divided into transmission con-trolled areas and endemic controlled areas in Hubei Province,middle school students from different types of areas were selected through stratified randomized cluster sampling and were investigated by questionnaire. Results A total of 3 204 students were se-lected and investigated. The awareness rate of schistosomiasis prevention and control knowledge among the students ranged from 65.1%-90.3%. Overall,the students from endemic controlled areas had higher knowledge rates of all the items than those from transmission controlled areas(all P<0.05). The middle school students acquired schistosomiasis prevention knowledge mainly from the teachers,parents,doctors and schistosomiasis staff. Conclusion Health education to students should adopt different ways targeting at different endemic levels in the future.

ObjectiveTo discuss the method and significance of concentric circumareolar approach in treatment of gynecomastia.MethodsThe incision was designed with the patient in a standing position.The location of the new nipple was determined,around which a outer cycle with the diameter of 5 cm was marked.And then a concentric inner circle with the diameter of 2.5 -3 cm was marked around the original nipple.The bilateral nipple position should be on the same level.A rim of tissue around the nipple-areola complex( NAC )was deepithelialized,excision of excess glandular tissue was performed subcutaneously and vascular network of dermis was preserved as much as possible.The purse string suture was applied in the circumareolar incision.Results 30 patients with gynecomastia were treated with this method.The result of the operation was pleasing with good aesthetic appearance,normal blood supply,and inconspicuous scars.Conclusion As a surgical approach of gynaecomastia,concentric circumareolar incision can remove excess glandular tissues and redundant skin,and has the benefit of concealing incision,simple procedure and satisfactory outcome.

BackgroundSeveral cornea collagen crosslinking methods have been used to treat keratoconus.However,the safety of these methods is dissatisfactory.Glyceraldehyde is a very potent and highly reactive crosslinking agent,with little toxicity,but its effect on corneal biomechanical property is poorly clear.ObjectiveThe aim of this study was to evaluate the biomechanical effects of glyceraldehyde collagen crosslinking on rats cornea.Methods Fifteen clean SD rats were randomly divided into 0.005 mol/L glyceraldhyde group,0.050 mol/L glyceraldhyde group and blank control group.Glyceraldhyde drops was topically administered in the right ryes 2 times per day for consecutive 7 days in the 0.005 mol/L and 0.050 mol/L glyceraldhyde groups,and no any eye drops was used in the blank control group.Seven days later,the rats were sacrificed.Transparency of corneal buttons in these different groups was evaluated.The central corneal strips of 2 mm×6 mm with 2 mm scleral tiasue were obtained for the biomeehanical stress-strain measurement,including ultimate stress ( MPa),ultimate strain (％) and 6％ elastic modulus (MPa).Corneal collagen fibril density was assessed by histological examination under a light microscopy.The use of the animals followed the Regulations for the Administration of Affair Concerning Experimental Animals by State Science and Technology Commission.ResultsThe words could be clearly displayed transcorneally in all the three groups.When strain was 6％,the stress was (0.463±0.065 ) MPa in 0.005 mol/L glyceraldehyde group,(0.846±0.240) MPa in 0.050 mol/L glyceraldehyde group,both showing a significant increase in comparison with (0.195±0.103 ) MPa of the blank control group (P=0.029,0.000 ).Following the crosslinking treatment,the ultimate stress was significant elevated in 0.050 mol/L glyceraldehydes group compared with the blank control group ( ( 10.759 ± 3.337 ) MPa vs.(5.295± 1.313 ) MPa,P =0.007 ),but no significant change between the 0.005 mol/L glyceraldehydes group and the blank control group ( ( 6.043 ±2.084) M Pa vs.(5.295 ± 1.313 ) MPa,P =0.660 ).Corneal ultimate strain was lower in the 0.005 mol/L glyceraldehyde group and 0.050 mol/L glyceraldehyde group than the blank control group (36.57％ ±3.09％ vs.43.87％ ± 1.89％,P =0.009;28.53％ ±1.89％ vs.43.87％ ± 1.89％,P =0.000).However,significantly increased 6％ elastic modulus were seen in the 0.005 mol/L glyceraldehyde group and 0.050 moL/L glyceraldehyde group compared with the blank control group ( ( 7.718 ± 1.076 ) MPa,( 14.102 ± 4.011 ) MPa vs.( 3.252 ± 1.717 ) M Pa),with statistically significant differences ( P =0.029,0.000).Histological examination showed a increase of collagen fiber density in the 0.050 mol/L glyceraldehyde group.Conclusions Corneal collagen crosslinking induced by glyceraldehyde strengthens biomechanical intensity and increases the density of corneal collagen fiber.But the safety of glyceraldehyde crosslinking for keratoconus needs further study.
