AIM: To investigate therapeutic effects of combination therapy for neovascular glaucoma ( NVG) .
METHODS: This retrospective study comprised 34 eyes of 34 patients who suffered from NVG. All patients were assigned to group A, B, C and D according to the different combination therapies. Group A ( 11 eyes of 11 patients ) was treated with intravitreal injection of ranibizumab and panretinal photocoagulation ( PRP ) . Group B ( 10 eyes of 10 patients ) was treated with transcleral cyclophotocoagulation and PRP. Group C ( 6 eyes of 6 patients) was treated with 3 therapies together. Group D (7 eyes of 7 patients) was treated with 810nm transcleral cyclophotocoagulation and soft gas-permeable contact lenses. All the patients were followed-up for 1a. The best- corrected visual acuity ( BCVA ) , intraocular pressure ( IOP ) were recorded and analyzed prior to operation and 1, 4wk, 6 and 12mo after operation.
RESULTS: All the post treatment IOP decreased significantly ( P<0. 05 ) from the values before therapy, and the IOP values after 4wk, 6, 12mo were not significantly different ( P > 0. 05 ) in statistics. Most patients' IOP can be controlled below 23mmHg after combination therapy. The visual acuity in group A after 1, 4wk, 6mo compared with those before treatment was significantly increased ( P<0. 05 ) in statistics and other groups did not significantly change before and after treatment (P>0. 05). Anterior chamber bleeding occurred to 2 cases after 1wk of transcleral cyclophotocoagulation. No other ocular or systemic adverse events were found during the follow-up duration.
CONCLUSION: After the combination of intraocular injection of the anti - VEGF drugs, 810nm laser cyclophotocoagulation and PRP, most patients with NVG disease can be effectively treated, can effectively control IOP, and retain part of the visual function, significantly improve the quality of life. In the short - term, combination therapy is safe and effective for NVG, which provides us an available strategy to conquer NVG by simply programmable operation and less suffering.

Background The combination procedure of the removal of silicon oil and cataract extraction+intraocular lens (IOL) implantation is the main method of treating cataract in silicone oil tamponade eye.However,the conventional measuring method of the IOL power is limiting in eyes with silicone oil tamponade.The IOL-Master system is confirmed to be an ideal non-contact optical measuring instrument in vivo.Objective The aim of this study is to measure the preoperative IOL power,evaluate the accuracy of biometry with the IOL-Master system and compare the relationship between different factors and refractive error.Methods IOL power was measured in 29 silicone oil tamponade eyes of 29 patients prior to the silicone oil removal combining IOL implantation with the IOL-Master system according to different factors such as placement time,axis oculi,complications and so on.The reasons of visual acuity recovery and measurement error were discussed.Results Postoperative visual acuity was improved in all of the patients.The average predictive refractive error was 0.329±0.846 (-1.5--2D).Classified factors for the cause of disease for axis oculi included rhegmatogenous retinal detachment (RRD)(t=0.478,P=0.637),macular hole(t=0.135,P=0.895),myopia(t=0.435,P=0.667)and oil-placed time (good for less than 1 year).These factors showed an indirect relationship with errors.Conclusion Silicone oil removal combined with IOL implantation can improve visual acuity.The IOL-Master biometry is accurate,safe and convenient in measuring the IOL power in silicon oil temponade eye,but future research should be performed to decrease the measuring error.

34 patients who suffered from NVG, excluding patients with shallow anterior chamber.All patients were assigned to groups A and B according the different therapy.Group A ( 15 eyes ) was treated with Ex -PRESS glaucoma filtration device implantation. Group B ( 19 eyes ) underwent a trabeculectomy combined with mitomycin C. All the patients were followed up to 1a.The results of best-corrected visual acuity ( BCVA ) , intraocular pressure ( lOP ) , the combination of lOP lowering medications, complications were recorded statistically analyzed preoperative and 1d, 1, 4wk, 6 and 12mo after operation. · RESULTS: Mean lOP decreased significantly frompreoperative values in both groups ( P=0.01 ) .The both group had similar lOP values changes after 1, 4wk, 6, 12mo, and there were no significant difference in statistics (P=0.451).There was no significant difference in BCVA changes after operation in both groups ( P =0.832).Success rate was 66.7%and 63.1%at 1a after Ex-PRESS glaucoma filtration device and trabeculectomy, respectively. Anterior chamber bleeding occurred to 8 cases after trabeculectomy in group B and to 3 cases with Ex-PRESS glaucoma filtration device implantation in group A.Choroidal detachment occurred to 3 cases in
group A and 6 cases in group B. No other ocular or systemic adverse events were found during the follow-up duration.

Objectives To explore the influence of standardized treatment and technical flow improvement on the diagnosis and treatment of congenital diaphragmatic hernia (CDH) after prenatal diagnosis. Methods The clinical data of neonates diagnosed with CDH who were hospitalized in neonatal intensive care unit from January 2005 to August 2016 was analyzed retrospectively. Based on the start time of standardized treatment implementation, 93 cases of CDH hospitalized from January 2010 to August 2016 were divided into the intervention group while 15 cases of CDH hospitalized from January 2005 to December 2009 were divided into the control group. The survival rate and complications of clinical outcomes between two groups were compared. Results There was no significant difference in sex, gestational age, birth weight, Apgar score, and CDH position between two groups (P >0.05). The total survival rate was 81.7％ in the intervention group and 53.3％ in the control group, and there was statistical difference (P<0.05). The difference of mechanical ventilation mode and pneumothorax rate between two groups also had statistical difference (P >0.05). The median operation time in the control group was 4.5 h and the intervention group was 49.5 h. The postoperative survival rate was 61.5％ in the control group and 90.5％ in the intervention group, and the differences between two groups were significant (P >0.05). The first blood gas analysis of deaths cases in both groups showed that there were significant differences in pH and PCO2 values (P >0.05). Conclusions Optimization of the clinical management during perioperative period can improve the survival rate of CDH and reduce complications. However, the dead cases in the intervention group had more severe pulmonary hypoplasia.

BACKGROUND: More and more patients with periodontal disease require orthodontic treatments. Thus, the remodeling process and its mechanism of inflammatory periodontal tissues become a hot point during orthodontic tooth movement.OBJECTIVE: To observe the remodeling of inflammatory periodontal tissues during orthodontic tooth movement.METHODS: A total of 50 Sprague Dawley rats were randomly divided into the control and periodontitis groups. In the periodontitis group, rats were established periodontitis models. After that, all rats were prepared for orthodontic tooth movement models. The remodeling of periodontal tissues was observed by hematoxylin-eosin staining at 1, 3, 5, 7 and 14 days after orthodontic tooth movement.RESULTS AND CONCLUSION: The movement distance of the periodontitis group was greater than that of the control group. At 0-7 days after orthodontic force application, there was obviously bone resorption at the pressure side and the bone formation was inhibited at the tension side; at 14 days after force application, the bone resorption was diminished, associated with large numbers of multinucleated osteoclasts at the pressure sides in both groups. The findings showed that rats with periodontitis suffered more periodontal traumatism during orthodontic tooth movement, thus, treatment should be delayed until the inflammatory signs were controlled and the local inflammatory was eliminated.

Objective To analyze risk factors for soft-tissue defects after surgery on leg trauma,to discuss methods for prevention of soft-tissue defects and its treatment.Methods A retrospective analysis was conducted on 217 cases of soft-tissue defects with bone exposure and / or internal fixation exposure after surgery on leg trauma from January,1999 to December,2012.Soft-tissue defects with various flaps were used in 201 cases,including neurocutaneous flap(89 cases),random flap(21 cases),free flap(75 cases),cross-leg flap(16 cases),and by skin grafting in 16 cases.For the 117 internal plate-fixated fractures,96 removed the plate and 21 cases did not remove the plate.For the 13 intramedullary nail fixations,4 cases of intramedullary nails were removed,9 cases were not removed.For the 56 cases of external fixation of the fractures,39 patients had unadjusted external fixation,17 cases re-adjusted external fixations.Results Of the 217 cases of soft-tissue defect after surgery on legs,201 cases were conducted flap surgery.The flap was completely necrosis in one case,and partial distal necrosis were in 14 cases,of which 6 cases healed after changing the dressing,5 underwent debridement and skin grafting,3 cases underwent flap surgery again.In cases of fracture patients,177 cases healed within 1 year,delayed union 23 cases,nonunion eight cases.Nonunion healing after bone grafting and re-fixation surgery.In 9 cases of uncontrollable osteomyelitis,6 patients underwent bone removal and bone transport surgery,3 patients underwent amputation.Conclusion Soft-tissue defects after surgery on leg trauma is a serious complication whose prevalence is associated,in a certain degree,with incorrect surgical time and methods.It is crucial for early repair of soft-tissue defects by using various kinds of proper flaps whenever soft-tissue complication occurs.In patients with early stage internal fixation,flap surgery without internal fixation removing is feasible if little soft-tissue defect,little exposed internal fixation and mild infection,otherwise it is necessary to remove internal fixation and re-fix by external fixation before flap surgery.

AIM: To build an allergic rhinitis model to evaluate the effect of budesonide on the eosinophils and histamine in nasal mucosa in allergic rhinitis guinea pig.METHODS: 33 guinea pigs were randomly divided into three groups: natural controlled group,allergic rhinitis(AR) group and budesonide treatment group.Allergic rhinitis model in guinea pigs were built by using toluene-2,4-disocyanate(TDI) nasal immunization and challenge.The indexes of clinical symptoms,pathomorphological diagnosis and content of histamine in mucosa were used to evaluate the potency of budesonide when used to treat allergic rhinitis.RESULTS: The expression of eosinophils and the content of histamine in nasal mucosa in AR group both were significantly higher than that of in natural controlled group(respectively,P(0.05)).CONCLUSION: Budesonide could effectively reduce the expression of eosinophils and content of histamine in nasal mucosa,but it is invalid in releasing the symptoms of AR in guinea pig.The reason of this phenomenon may be concerned with the method of model building.
