Objective To probe the classification of diabetic retinopathy (DR) and the different grade of diabetic and type of macular edema according to fundus fluorescein angiography (FFA). Methods FFA was performed on 1 058 patients (2 097 eyes) to classify DR and macular edema with the analysis of duration of DM, visual acuity, manifestation of FFA images and results of ophthalmoscopic examination. Results In 2 097 eyes, there were 124 (5. 9%) without DR, 396 (18. 9%) with DR I, 430 (20. 5%) with DR II, 563 (26.8%) with DR III, 262 (12. 5%) with preproliferative diabetic retinopathy ( PPDR), 254 (12.%) with DR IV, 60 (2. 9%) with DR V, and 8 (0. 4%) with DR VI. In 2 097 eyes there were 819 (39. 1%) with macular edema, including 311 (38%) with focal macular edema, 322 (39. 3%) with diffused macular edema, 112 (13. 7%) with cystoid macular edema, 25 (3. 1%) with ischemia macular edema, and 49 (6. 0%) with proliferative macular edema. Conclusion With the analysis of the results of FFA of 2 097 eyes, we classify DR in stage Ⅰ (primary stage Ⅰ and Ⅱ), Ⅱ (primary stage Ⅲ), Ⅲ (preproliferative diabetic retinopathy), Ⅳ,Ⅴ, and Ⅵ; classify macular edema of DR in focal, diffused, cystoid, ischemic, and proliferating ones.

Objective To investigate methods and experience of autologous granular fat transplantation by correction of aging face. Methods 178 cases of aging face subjects were treated by liposuction. Then autologous granular fat was harvested by liposuction,centrifuged and purified, and injected into marked areas of aging face. The injection process should be controled by multilevel and multiple tennel, in order to supplement the loss of facial soft tissue volume and improve the aging face. Results The follow-up period ranged from 3 months to 3 years. All the subjects had a satisfactory results with no obvious complications such as fat liquefaction, infection and ulceration. The effect of autologous granular fat transplantation was obvious and permanent. Conclusions Autologous granular fat transplantation is a safe and effective surgical technique for facial soft tissue augmentation that can effectively improve aging face and worthy of clinical application.

Objective To comprehensively analyze the clinical outcomes of total cavopulmonary connection (TCPC) in the treatment of functional single ventricle combined with heterotaxy syndrome (HS). Methods A retrospective analysis was conducted on the patients with functional single ventricle and HS who underwent TCPC (a HS group) in Guangdong Provincial People's Hospital between 2004 and 2021. The analysis focused on postoperative complications, long-term survival rates, and identifying factors associated with patient survival. Early and late postoperative outcomes were compared with matched non-HS patients (a non-HS group). Results Before propensity score matching, 55 patients were collected in the HS group, including 42 males and 13 females, with a median age of 6.0 (4.2, 11.8) years and a median weight of 17.0 (14.2, 28.8) kg. Among the patients, there were 53 patients of right atrial isomerism and 2 patients of left atrial isomerism. Eight patients underwent TCPC in one stage. TCPC procedures included extracardiac conduit (n=39), intracardiac-extracardiac conduit (n=14), and direct cavopulmonary connection (n=2). Postoperative complications included infections in 27 patients, liver function damage in 19 patients, and acute kidney injury in 11 patients. There were 5 early deaths. The median follow-up time was 94.7 (64.3, 129.8) months. The 1-year, 5-year, and 10-year survival rates were 87.2%, 85.3%, and 74.3%, respectively. After propensity score matching, there were 45 patients in the HS group and 81 patients in the non-HS group. Compared to the non-HS group, those with HS had longer surgical and mechanical ventilation time, higher infection rates (P<0.05), and a 12.9% lower 10-year survival rate. Multivariate Cox regression analysis identified asplenia was a risk factor for mortality (HR=8.98, 95%CI 1.86-43.34, P=0.006). Conclusion Compared to non-HS patients, patients with HS have lower survival rates after TCPC, and asplenia is an independent risk factor for the survival of these patients.
