Objective To investigate the value of ¹⁸F-FDG PET/CT metabolic parameters in the prognostic assessment of nasopharyngeal cancer patients. Methods The clinical data and PET/CT metabolic parameters of 185 nasopharyngeal cancer patients were retrospectively analyzed. The collected parameters were SUV_max, MTV, TLG, total metabolic tumor volume (TMTV) and whole-body total lesion glycolysis (WTLG). The ROC curve was used to determine the optimal cut-off values of PET/CT metabolic parameters. Univariate and multivariate Cox regression models were used to screen the independent prognostic factors. Kaplan–Meier curves were used to analyze the survival differences. Results The results of univariate Cox regression analysis showed that age, pathologic type, WTLG, TMTV, MTV, and TLG were closely associated with OS and PFS; and SUV_max was associated with PFS (P<0.05). Multivariate Cox regression analysis results showed that age, TMTV, and WTLG were the independent prognostic factors for OS and PFS (P<0.05). The combination of WTLG with T/N staging (AUC=0.781 and 0.781) and TMTV with T/N staging (AUC=0.800 and 0.790) yielded greater predictive accuracy than that of WTLG and TMTV alone (AUC=0.724 and 0.719) or T/N staging (AUC=0.593 and 0.575). Conclusion TMTV and WTLG are important prognostic predictors of nasopharyngeal carcinoma. TLG and MTV of primary lesions are prognostic factors for patients’ PFS and OS. SUV_max has limited prognostic value. Systemic metabolic indexes (TMTV and WTLG), when combined with T/N staging, can optimize prognostic stratification.

Chronic limb-threatening ischemia(CLTI)is a serious peripheral arterial disease(PAD)characterized by reduced blood flow in the limbs,resulting in tissue damage and dysfunction.Mesenchymal stem cells(MSCs)have become a research hotspot in the field of CLTI treatment in recent years due to their unique regenerative ability and immunomodulatory properties.In the environment of hypoxia and tissue injury,MSCs can promote angiogenesis,reduce inflammation and promote tissue repair by secreting cytokines,cell differentiation and inter-cellular signal transduction,so as to improve the symptoms and prognosis of patients with CLTI,showing a broad clinical application prospect.

Objective To investigate the clinical efficacy and safety of endoscopic ultrasonography-guided(EUS-guided)enterocolon anastomosis in treating patients with malignant bowel obstruction(MBO).Methods The clinical data of 12 patients with MBO,who underwent EUS-guided enterocolon anastomosis at the Nanjing Drum Tower Hospital of China from April 2023 to December 2023,were collected.The perioperative clinical efficacy and safety were retrospectively analyzed.Results Successful EUS-guided enterocolon anastomosis was accomplished in all the 12 patients,with a technical success rate of 100％(12/12).The clinical success rate was 83.3％(11/12),one patient developed obstruction of the stent.The clinical symptoms were relieved in 2-68 hours after treatment,and the time to resume defecation and exhaust was(18.02±15.75)hours.Within one week after the operation,4 patients took liquid diet and 8 patients took semi-fluid diet.Each dimension score of the Quality of Life Core-30 scale of The European Organization for Research and Treatment of Cancer(EORTC QLQ-C30)was remarkably improved,the patient's overall health score was increased from preoperative median 5 points to postoperative 8 points(P＜0.001).During the operation,stent displacement occurred in 2 patients,and the operation was successfully completed after promptly taking remedial measures.After operation,11 patients developed fever(37.5-39.4 ℃),and all the patients were discharged smoothly after symptomatic treatment.No complication such as bleeding,perforation,or stent displacement occurred.Conclusion EUS-guided enterocolon anastomosis is clinically safe and effective,it can effectively relieve the clinical symptoms and improve the quality of life of patients with MBO.

Objective:To evaluate long-term outcomes of endoscopic papillectomy (EP) for duodenal papillary adenomas and to identify risk factors for incomplete resection.Methods:Clinical data of 180 patients diagnosed as having duodenal papillary adenoma via postoperative pathology after EP in Nanjing Drum Tower Hospital, the Affiliated Hospital of Nanjing University Medical School from January 2010 to December 2022 were retrospectively analyzed. Patients were divided into two groups based on their postoperative margin status: the complete resection group (negative resection margins) and the incomplete resection group (positive/uncertain resection margins). Recurrence rates were compared between the two groups, and logistic regression analysis was performed to identify risk factors for incomplete resection.Results:Among the 180 patients included in the study, 137 underwent complete resection, and 43 had incomplete resections. Recurrence rate was significantly higher in the incomplete resection group than that in the complete resection group (30.2% VS 15.3%, χ2=4.75, P=0.029). logistic regression analysis indicated that high-grade intraepithelial neoplasia was an independent risk factor for incomplete resection ( OR=2.43, 95% CI:1.12-5.26, P=0.024). Conclusion:Patients with incomplete resection after EP have a higher recurrence rate in the long-term follow-up. High-grade intraepithelial neoplasia is an independent risk factor for incomplete resection. Close surveillance and aggressive management are warranted for patients with positive or uncertain resection margins to mitigate the recurrence risk.

Objective:To investigate long-term auditory changes and characteristics of Alport syndrome（AS） patients with different degrees of renal injury. Methods:Retrospectively analyzing clinical data of patients diagnosed AS from January 2007 to September 2022, including renal pathology, genetic detection and hearing examination. A long-term follow-up focusing on hearing and renal function was conducted. Results:This study included 70 AS patients, of which 33（25 males, 8 females, aged 3.4-27.8 years） were followed up, resulting in a loss rate of 52.9%.The follow-up period ranged from 1.1to 15.8 years, with 16 patients followed-up for over 10 years. During the follow-up, 10 patients presenting with hearing abnormalities at the time of diagnosis of AS had progressive hearing loss, and 3 patients with new hearing abnormalities were followed up, which appeared at 5-6 years of disease course. All of which were sensorineural deafness. While only 3 patients with hearing abnormalities among 13 patients received hearing aid intervention. Of these patients,7 developed end-stage renal disease（ESRD）, predominantly males （6/7）. The rate of long-term hearing loss was significantly different between ESRD group and non-ESRD group（P=0.013）. There was no correlation between the progression of renal disease and long-term hearing level（P>0.05）. kidney biopsies from 28 patients revealed varying degrees of podocyte lesion and uneven thickness of basement membrane. The severity of podocyte lesion was correlated with the rate of long-term hearing loss（P=0.048）, and there was no correlation with the severity of hearing loss（P>0.05）. Among 11 cases, theCOL4A5mutationwas most common （8 out of 11）, but there was no significant correlation between the mutation type and hearing phenotype（P>0.05）. Conclusion:AS patients exhibit progressive hearing loss with significant heterogeneity over the long-term.. THearing loss is more likely to occur 5-6 years into the disease course. Hearing abnormalities are closely related to renal disease status, kidney tissue pathology, and gene mutations, emphasizing the need for vigilant long-term hearing follow-up and early intervention.

Objective:To investigate the efficacy and safety of fat suction combined with bipolar radiofrequency on face and neck rejuvenation.Methods:A total of 115 patients with face and neck fat deposits and skin laxity underwent fat suction combined with bipolar radiofrequency between December 2021 and October 2022 by the same surgeon in Changsha My Like Medical Cosmetology Hospital. There were 3 men and 112 women in this research. The mean age was 36.1 years (range, 26-55 years) and the mean body mass index was 21.4 (range, 16.8-27.7 kg/cm 2). Postoperative patient satisfaction surveys were conducted and 2 independent doctors evaluated clinical effect with preoperative and postoperative photographs at 3-6 months postoperatively. Results:The mean amount of fat aspirated was 44.5 ml (range, 10-92 ml) and the mean energy delivered was 4.5 kJ (range, 2.1-8.9 ml). 88.7% of patients were satisfied with their postoperative effect (102/115 patients). 92.2% of doctors were satisfied with the postoperative effect (106/115 patients). Four out of 115 patients (3.5%) developed irregularity by fat suction.Conclusions:Fat suction combined with bipolar radiofrequency can effectively reduce the fat accumulation of facial and neck and significantly improve skin relaxation. It is an effective method to rejuvenate facial and neck.

Objective:To provide data support for the improvement of aeromedical support by summarizing the disease characteristics and analyzing the change pattern of disease spectrum for the temporarily grounded military flying personnel assessed in the annual physical examination.Methods:The clinical data of military flying personnel who were assessed as temporary grounding in the annual physical examination in Air Force Healthcare Center for Special Services Hangzhou from 2012 to 2021 were retrospectively analyzed. They were divided into 2012—2016 group and 2017—2021 group with a 5-year span. The distributions of disease, age and aircraft type were statistically compared between 2 groups of temporarily grounded military flying personnel.Results:A total of 522 flying personnel, aged from 23-55 years and flew 100-20 000 h, were enrolled. There were 242 cases in 2012—2016 group and 280 cases in 2017—2021 group. Compared with 2012—2016 group, 2017—2021 group was found 9 new diseases. Among the top 10 diseases in 2017—2021 group, the proportion of pulmonary nodules, hypertension, diabetes, abnormal tumor indicators, positive fecal occult blood was increased, and the proportion of thyroid nodules, abnormal liver function, arrhythmia was decreased. There was a significant difference in the age distribution between 2 groups of temporarily grounded military flying personnel ( χ2=20.97, P<0.001). The proportion of flying personnel aged ≥40 years old was increased in 2017—2021 group. The proportion of fighter-trainer pilots and bomb-transporter flying personnel increased in 2017—2021 group, and the difference was significant ( χ2=14.66, P=0.001). Conclusions:In recent years, more diseases, mostly occult diseases, are found in the disease spectrum of the temporarily grounded military flying personnel. Since some insidious diseases require more time to observe their convalescent effect and the influence to flight but the routine phone follow-up is called within 2 months of discharge, so a long-term and effective follow-up mechanism is suggested.
