Objective To investigate the clinical effects of vitrectomy combined with cataract surgery in the treatment of proliferative diabetic retinopathy (PDR V-VI stage).Methods A total of 80 patients with proliferative diabetic retinopathy from January 2012 to January 2014 were divided into the single group and the combined group according to the surgical method.Patients of the single group were treated by vitrectomy while patients of the combined group were treated by vitrectomy combined with cataract surgery.The incidence of retinal reattachment,postoperative vision and surgical complications between the two groups were compared.Results Compared with the single group,the incidence of retinal reattachment was higher in combined group (P ＜ 0.05).The postoperative vision improvement was better than that in single group,the difference was significant (P ＜ 0.05).And the surgical complications in combined group was less than that in single group,the difference was significant (P ＜ 0.05).Conclusion Vitrectomy combined with cataract surgery in the treatment of proliferative diabetic retinopathy has a better clinical effect which is safe and reliable,and it can improve the rate of retinal reattachment and reduce surgical complications.

Objective To evaluate the outcome of surgical treatment of tricuspid valve regurgitation after valve replacement.Methods Twenty one patients with tricuspid valve insufficiency after valve replacement were performed surgical treatment.Tricuspid valve-plasty was performed in 17 patients and tricuspid valve replacement was done in 4 patients.Three patients underwent edge-to-edge tricuspid valveplasty.DeVega procedure was performed in 5 patients.Cosgrove-Edward annuloplasty ring was used in 15 patients.Four patients' valve were replaced by SJM bileallet mechanical prostheses.Results There was 3 patients dead early after operation with a mortality of 14.3％(3/21).The causes of death including multiple organ failure,cardiac arrest and low cardiac output syndrome.The rate of early postoperative complications was 33.3％ (7/21),including pulmonary edema,arrhythmia,acute renal failure and low cardiac output syndrome.The patients were followed up 9-60 months.The rate of readmission was 23.8％ (5/21).Two patients went to hospital again for pleural effusion,1 patient for left ventricular dysfunction and 2 patients for right ventricular dysfunction.The other patients recovered well.Conclusions Surgical therapy is effective on severe tricuspid valve regurgitation after valve replacement.Preoperative aggressive treatment of heart failure,a reasonable grasp of surgical indications and timing of surgery,strict perioperative management are the keys to guarantee patients a smooth recovery.
