Objective To evaluate the effect of argon laser photocoagulation (photocoagulation group) and endolaser photocoagulation during vitrectomy (vitrectomy group) on the eyes with Eales disease by fundus fluorescein angiography(FFA) and visual acuity (VA).Methods Sixty-seven eyes with Eales were treated by photocoagulation and 31 eyes with Eales were treated by vitrectomy. The changes of FFA and VA before and after treatment were observed.Results In the photocoagulation group, retinal non-perfusion disappeared in 31eyes(55 4%),alleviated in 17eyes(30 4%),unchanged in four eyes(7 1%)and deteriorated in four eyes(7 1%).Retinal neovascularization disappeared in 30 eyes(50 8%),alleviated in 19 eyes (32 2%),remained in six eyes(10 2%)and deteriorated in four eyes(6 8%).The first FFA after treatment, non-perfusion was existed in 25 eyes in photocoagulation group, and only was existed in two eyes in vitrectomy group.Neovascularization was existed in 29 eyes in photocoagulation group, and was existed in three eyes in vitrectomy group.The best visual correction(VA≥3 0) in photocoagulation and vitrectomy groups respectively was 30 eyes and zero eye before treatment,and after treatment respectively was 47 eyes and five eyes.There were 54 eyes and 11 eyes with VA≥0 05 in photocoagulation and vitrectomy groups respectively before treatment,and 60 eyes and 20 eyes with VA≥0 5 respectively after treatment.Conclusions The better result of FFA in vitrectomy group was related to the sufficient photocoagulation by endolaser. The higher rate of low vision in vitrectomy group was related to the impairment of macula by large amount of vitreous hemorrhages,retina detachment and vitrectomy. So the patients with Eales should be checked by FFA as early as possible.If the patients had the indicator to be treated by laser,they should be treated early and rechecked by FFA,to avoid the visual function harm by repeated vitreous hemorrhage due to incomplete treatment.

Objective:To investigate the therapeutic effect of cardiac rehabilitation exercise on ventricular remodeling in patients with acute myocardial infarction undergoing percutaneous coronary intervention.Methods:A total of 100 patients with acute myocardial infarction undergoing percutaneous coronary intervention who received treatment in Wenzhou Central Hospital from June 2018 to June 2019 were included in this study. They were randomly divided into a rehabilitation group and a conventional treatment group ( n = 50/group). Patients in the conventional treatment group underwent conventional postoperative rehabilitation education while those in the rehabilitation group received targeted cardiac rehabilitation exercise. After surgery, all patients were followed up for 12 months. Real time three-dimensional echocardiography was used to evaluate ventricular remodeling (left ventricular ejection fraction, left ventricular end-diastolic volume , left ventricular end-systolic volume, left ventricular remodeling index) and ventricular synchrony (Tmsv-16dif, Tmsv-16sd, Tmsv16-dif%, Tmsv16-sd%) before and 3, 6 and 12 months after surgery. In addition, serum levels of ventricular remodeling indexes (fibroblast growth factor 23, PICP and PIIINP) were measured. The incidence of cardiovascular end-point events within 12 months was calculated. Results:At 3, 6 and 12 months after surgery, left ventricular ejection fraction was (51.81 ± 5.43)%, (55.88 ± 5.46)%, (55.63 ± 5.57)% in the rehabilitation group, which was significantly higher than (47.16 ± 5.38)%, (52.31 ± 5.44)%, (51.84 ± 5.59)% respectively in the conventional treatment group ( t = 4.302, 3.275, 3.396, all P < 0.05). At 3, 6 and 12 months after surgery, left ventricular end-diastolic volume was (124.65 ± 15.56) mL, (98.54 ± 14.54) mL, (99.82 ± 13.18) mL, respectively in the rehabilitation group, which was lower than (132.64 ± 16.58) mL, (112.55 ± 15.61) mL and (114.84 ± 17.35) mL, respectively in the conventional treatment group ( t = 2.485, 4.644, 4.874, all P < 0.05). At 6 and 12 months after surgery, left ventricular end-systolic volume was (52.26 ± 5.48) mL and (52.15 ± 5.32) mL respectively in the rehabilitation group, which was significantly lower than (57.92 ± 5.46) mL and (58.51 ± 5.72) mL in the conventional treatment group ( t = 5.174, 5.757, both P < 0.05). At 6 and 12 months after surgery, left ventricular remodeling index was (1.75 ± 0.42) g/mL and (1.74 ± 0.35) g/mL respectively in the rehabilitation group, which was significantly higher than (1.52 ± 0.37) g/mL and (1.50 ± 0.32) g/mL, respectively in the conventional treatment group ( t = 2.906, 3.579, both P < 0.05). At 3, 6 and 12 months after surgery, Tmsv-16dif ( t = 2.753, 4.283, 4.088, all P < 0.05), Tmsv-16sd ( t = 5.134, 4.326, 4.670, all P < 0.05), Tmsv-16dif% ( t = 7.714, 8.587, 7.800, all P < 0.05) and Tmsv16-sd% ( t = 9.004, 14.061, 10.305, all P < 0.05) respectively in the rehabilitation group, were significantly lower than those in the conventional treatment group. At 3, 6 and 12 months after surgery, fibroblast growth factor 23 ( t = 6.303, 5.053, 4.619, all P < 0.05). PICP ( t = 3.772, 2.798, 3.788, all P < 0.05) and PIIINP ( t = 3.110, 5.912, 4.294, all P < 0.05) in the rehabilitation group were significantly lower than those in the conventional treatment group. Within 12 months, the total incidence of cardiovascular end-point events in the rehabilitation group [12.00% (6/50)] was significantly lower than that in the conventional treatment [32.00% (16/50)] ( χ2 = 5.828, P < 0.05). Conclusion:Cardiac rehabilitation exercise can improve ventricular remodeling and synchrony in patients with acute myocardial infarction undergoing percutaneous coronary intervention and reduce the incidence of cardiovascular end-point events.

Objective To investigate correlation between the amount of interleukin-17 (IL-17) producing cells and the expression of transforming growth factor (31 (TGF-β1) in glioma,and evaluate the clinical values of IL-17 and TGF-pl in predicting the prognosis of glioma. Methods The presence of IL-17 and TGF-pl was measured by immunohistochemistry in 135 human glioma (WHO Ⅰ 18,WHO Ⅱ 45,WHO Ⅲ 53,WHO Ⅳ 19) tissues and 15 normal brain tissues. Results There was no IL-17 positive staining in normal brain tissues. Of 135 glioma specimens showed low TGF-pl expression and 77 (57. 03% ) showed high TGF-pl expression. No TGF-β1 expression was detected in normal brain tissue. Furthermore,TGF-β1 expression was positively correlated with the amount of IL-17 producing cells in glioma tissues ( r=0.285, P<0.01). Compared with the low grade,the levels of IL-17 and TGF-pl positive cells were obviously increased in high grade. The Kaplan-Meier analysis showed that there were significant differences in overall survival (OS) between the IL-17 and TGF-pl high-expression and lowexpression group (P<0.01, P<0.05). The 3-year OS rates of IL-17 of high expression and low expression were 33.75% and 76. 36%. Multivariate Cox proportional hazards regression analysis indicated that age,KPS score, IL-17 were independent prognostic factor for OS (P<0.01). Conclusion Intratumoral IL-17-producing cell density and the expression of TGF-β1 was associated with the malignancy of human glioma.
