Objective:To analyze the real experience of elderly patients with chronic heart failure and type 2 diabetes in dealing with abdominal distension, and to provide a basis for medical staff to formulate targeted intervention strategies.Methods:Using the purpose sampling method, semi-structured interview was conducted on elderly patients with chronic heart failure and type 2 diabetes who were admitted to Ruikang Hospital Affiliated to Guangxi University of Chinese Medicine from April 2024 to June 2024. Extract themes used Colaizzi 7-step analysis method.Results:There were 6 males and 8 femdes, aged 60-80 years old. A total of 4 themes and 10 sub-themes were extracted, namely somatic symptom distress (obvious related symptom clusters, aggravation of basic disease symptoms), emotional response differentiation (weakening of emotional control, positive psychological derivation), diversified coping strategies (negative coping included self-neglect and avoidance of medical treatment, positive coping included active medical treatment and self-adjustment), coping difficulties (lack of disease knowledge, contradiction of coping strategies, urgent need for optimization of TCM diagnosis and treatment, imperfect external support system).Conclusions:Medical staff should pay attention to the physical and mental feelings of elderly patients with chronic heart failure and type 2 diabetes in the process of abdominal distension coping, and provide targeted health guidance and comprehensive nursing, so as to reduce the physical symptoms of patients and promote their physical and mental health.

Objective:To evaluate the clinical outcomes of endoscopic-assisted polyether ether ketone (PEEK) patient-specific implant (PSI) revision for over-resected mandibles caused by the mandibular angle osteotomy.Methods:A retrospective analysis was conducted on 24 patients [8 males, 16 females, aged 19-57 (32.5±9.5) years] with 39 over-resected mandibles that underwent PEEK-PSI mandibular angle revision surgery at the Affiliated Friendship Plastic Surgery Hospital of Nanjing Medical University from January 2019 to December 2023. Preoperative cone-beam computed tomography (CBCT) data were used to design and fabricate customized PEEK PSIs based on individual anatomical requirements. An intraoral incision approach with endoscopic assistance was employed to meticulously dissect soft tissue attachment around the angle region, followed by the implantation of a customized PEEK PSI. Postoperative CBCT scans were performed for 3D reconstruction, with root mean square error (RMSE) and maximum deviation (MaxD) as accuracy metrics. Patients′ satisfaction was assessed preoperatively and ≥6 months postoperatively using the face questionnaire (FACE-Q) scores, which included overall facial appearance, lower face and jawline, appearance distress, psychological health and social function.Results:All 24 patients achieved satisfactory recovery with primary healing of intraoral incisions. No complications such as infection, nerve injury, or implant rejection occurred during follow-up period. Patients′ facial appearance and jaw line contouring were significantly improved. Fine anatomical fitting between PEEK-PSI and defect areas was observed: RMSE ranged from 0.117 to 0.315 mm, and MaxD was (5.485±1.300) mm. FACE-Q scores demonstrated significant improvements after surgery in overall facial appearance [(49.8±5.4) vs (65.0±5.3) scores], lower face and jawline [(42.5±5.3) vs (56.1±4.6) scores], appearance distress [(60.0±6.9) vs (70.6±6.5) scores], psychological health [(62.0±5.0) vs (70.8±5.3) scores], and social function [(60.3±4.3) vs (69.3±5.8) scores] (all P<0.001). Conclusion:Endoscopic-assisted PEEK-PSI revision for over-resected mandibles following mandibular angle osteotomy exhibits high surgical precision and safety, effectively restoring mandibular contour and significantly enhancing patients′ satisfaction.

Objective:To investigate the clinical outcomes of precapsular pocket repositioning for correcting implant malposition following augmentation mammoplasty.Methods:A retrospective analysis was conducted on 29 female patients aged 25-37 (28.8±3.4) years who underwent precapsular pocket repositioning at the Affiliated Friendship Plastic Surgery Hospital of Nanjing Medical University from December 2015 to August 2024. The surgical technique involved preserving the original capsule, creating a new implant pocket anterior to the capsule, and closing the original capsular space. Postoperative complications were recorded, and breast satisfaction was evaluated preoperatively and at 6 months postoperatively using the BREAST-questionnaire (BREAST-Q).Results:All 29 patients successfully underwent precapsular pocket repositioning with primary wound healing. During the follow-up period, all patients were satisfied with the correction of implant malposition. The mean BREAST-Q score improved significantly from (43.56±3.17) scores preoperatively to (72.56±13.49) scores at 6 months postoperatively ( P<0.001). No hematoma, implant rupture, recurrent malposition, capsular contracture, or surgical site infection occurred in any patient. Conclusion:Precapsular pocket repositioning provides favorable clinical outcomes for patients with implant malposition after augmentation mammoplasty, and there are no severe complications .

Objective:To investigate the clinical effect of the divisional design in composite labia minora and clitoral hood reduction.Methods:A retrospective analysis was performed on 57 patients diagnosed with labia minora and clitoral hood hypertrophy at Department of Plastic Surgery, Nanjing Medical University Friendship Plastic Surgery Hospital between July 2018 and May 2021. The ages of the patients ranged from 24 to 45 years with an average of (31.0±8.2) years. Preoperative symptoms and surgical demands included: appearance concerns in 57 cases (100%), irritation during friction in 49 cases (86.0%), and discomfort during intercourse in 22 cases (38.6%). The complex hypertrophy was divided into simple labia minora hypertrophy and clitoral hood hypertrophy. Then the reduction of clitoris hood was performed according to the prepuce morphology, and labiaplasty was performed using edge resection. The operative effects, patient satisfaction, and postoperative complications were assessed.Results:All incisions healed primarily with no flap necrosis or marginal infections. Hematoma occurred in 1 case which recovered well after timely treatment. All patients were followed up for 3-12 months. 54 cases were satisfied with the labia minora and clitoral hood shape and reported no sensory abnormality. Bilateral asymmetry occurred in 2 cases, one of which required further surgical repair. Scar hyperplasia occurred and was gradually softened after 6 months in 1 case. Of the 57 patients with appearance concerns, 55 (96.5%) patients reported improved appearance postoperatively. Of the 49 patients with preoperative friction discomfort, 47 (95.9%) patients achieved symptom relief. Of the 22 patients reporting sexual discomfort, 15 (68.1%) patients noted enhanced sexual satisfaction postoperatively. Overall, 54 (94.7%) patients were satisfied, 2 (3.5%) patients were moderately satisfied, and 1 (1.8%) patient was unsatisfied.Conclusions:For patients with labia minora and clitoral hood hypertrophy, the application of divisional design is surgically simple and safe. It achieves satisfactory outcomes with no severe adverse reactions.

Objective To compare the clinical outcomes and retinal volume changes in patients with ischemic and non-ischemic macular edema secondary to branch retinal vein occlusion(BRVO-ME)using optical coherence tomography angiography(OCTA).Methods The clinical data of 34 ischemic BRVO-ME patients(34 eyes,ischemic group)and 21 non-ischemic BRVO-ME patients(21 eyes,non-ischemic group)were retrospectively analyzed.Patients in both groups re-ceived intravitreal injections of ranibizumab.The best corrected visual acuity(BCVA)and retinal volume of the macular ar-ea were assessed before,1 day,1 week,1 month,3 months and 6 months after the treatment.Results The BCVA(log-MAR)at 1 day after the treatment was 0.63±0.37 in the ischemic group and 0.44±0.22 in the non-ischemic group,and the difference was statistically significant(P=0.017).The retinal volumes of the outer retina,the full retina,and the Farafovea and Perifovea subdivisions of the full retina before the treatment were(6.42±1.90)mm3,(8.75±1.82)mm3,(3.20±0.87)mm3 and(5.10±0.89)mm3 in the ischemic group and(5.52±1.57)mm3,(7.83±1.56)mm3,(2.80± 0.71)mm3,and(4.66±0.77)mm3 in the non-ischemic group,respectively;1 day after treatment,they were(4.97± 1.18)mm3,(7.46±1.47)mm3,(2.62±0.60)mm3 and(4.53±0.80)mm3 in the ischemic group and(4.25±0.48)mm3,(6.58±0.56)mm3,(2.26±0.26)mm3 and(4.06±0.40)mm3 in the non-ischemic group,respectively;at 1 week after the treatment,they were(4.40±0.82)mm3,(6.90±0.85)mm3,(2.38±0.36)mm3 and(4.24±0.49)mm3 in the ischemic group and(4.04±0.35)mm3,(6.33±0.49)mm3,(2.15±0.19)mm3 and(3.95±0.35)mm3 in the non-ische-mic group,respectively,and the differences between the two groups were statistically significant(all P＜0.05).The a-mount of retinal volume change from baseline in the outer retina and the full retina was(-2.48±2.38)mm3 and(-2.54±2.38)mm3 in the ischemic group,and(-1.31±1.58)mm3 and(-1.38±1.58)mm3 in the non-ischemic group at 1 month after treatment,respectively,and the differences between the two groups were statistically significant(both P＜0.05).Conclusion Ranibizumab is effective in treating both ischemic and non-ischemic BRVO-ME.The short-term visu-al prognosis is better in the non-ischemic group than the ischemic group,and the retinal volume is higher in the ischemic group than the non-ischemic group.However,no significant difference is observed in the visual prognosis or retinal volume between the two groups after long-term treatment.

BACKGROUND: Osteoarthritis (OA), a degenerative joint disorder, is a major reason of disability in adults. Accumulating evidences have proved that bone marrow mesenchymal stem cells (BMSCs)-carried exosomes play a significant therapeutic effect on OA. However, the precise regulatory network remains unknown. METHODS: OA and normal cartilage samples were acquired from patients, and chondrocytes were exposed to IL-1b to conduct a cellular OA model. Exosomes prepared from BMSCs were identified using nanoparticle tracking analysis (NTA) and transmission electron microscopy (TEM). Cell viability was determined with CCK-8 assay. Inflammatory injury was assessed by LDH and inflammatory factors (TNF-a and IL-6) using corresponding ELISA kits, respectively. Ferroptosis was evaluated by GSH, MDA and iron levels using corresponding kits, and ROS level with DCFH-DA. The expressions of genes/proteins were determined with RT-qPCR/western bolt. RNA immunoprecipitation and luciferase activity assay were conducted for testing the interactions of small nucleolar RNA host gene 7 (SNHG7)/ferroptosis suppressor protein 1 (FSP1) and miR-485-5p. RESULTS: The expressions of SNHG7 and FSP1 were both reduced in IL-1b-induced chondrocytes and OA cartilage tissues, and there was a positive correlation between them in clinical level. Moreover, SNHG7 was enriched in BMSCsderived exosomes (BMSCs-Exos) and could be internalized by chondrocytes. Functional analysis illustrated that BMSCsExos administration repressed inflammatory injury, oxidative stress and ferroptosis in IL-1b-induced chondrocytes, while these changes were reinforced when SNHG7 was overexpressed in BMSCs-Exos. Notably, FSP1 silencing in chondrocytes abolished the beneficial effects mediated by exosomal SNHG7. CONCLUSIONS Exosomal SNHG7 released from BMSCs inhibited inflammation and ferroptosis in IL-1b-induced chondrocytes through miR-485-5p/FSP1 axis. This work suggested that BMSCs-derived exosomal SNHG7 would be a prospective target for OA treatment.
