Hearing loss is the most prevalent disabling disease. Cochlear implantation（CI） serves as the primary intervention for severe to profound hearing loss. This consensus systematically explores the value of genetic diagnosis in the pre-operative assessment and efficacy prognosis for CI. Drawing upon domestic and international research and clinical experience, it proposes an evidence-based medicine three-tiered prognostic classification system（Favorable, Marginal, Poor）. The consensus focuses on common hereditary non-syndromic hearing loss（such as that caused by mutations in genes like GJB2, SLC26A4, OTOF, LOXHD1） and syndromic hereditary hearing loss（such as Jervell & Lange-Nielsen syndrome and Waardenburg syndrome）, which are closely associated with congenital hearing loss, analyzing the impact of their pathological mechanisms on CI outcomes. The consensus provides recommendations based on multiple round of expert discussion and voting. It emphasizes that genetic diagnosis can optimize patient selection, predict prognosis, guide post-operative rehabilitation, offer stratified management strategies for patients with different genotypes, and advance the application of precision medicine in the field of CI.

Ovarian tumor (OT) is the most lethal form of gynecologic malignancy, with minimal improvements in patient outcomes over the past several decades. Metastasis is the leading cause of ovarian cancer-related deaths, yet the underlying mechanisms remain poorly understood. Psychological stress is known to activate the glucocorticoid receptor (NR3C1), a factor associated with poor prognosis in OT patients. However, the precise mechanisms linking NR3C1 signaling and metastasis have yet to be fully elucidated. In this study, we demonstrate that chronic restraint stress accelerates epithelial-mesenchymal transition (EMT) and metastasis in OT through an NR3C1-dependent mechanism involving nuclear protein 1 (NUPR1). Mechanistically, NR3C1 directly regulates the transcription of NUPR1, which in turn increases the expression of snail family transcriptional repressor 2 (SNAI2), a key driver of EMT. Clinically, elevated NR3C1 positively correlates with NUPR1 expression in OT patients, and both are positively associated with poorer prognosis. Overall, our study identified the NR3C1/NUPR1 axis as a critical regulatory pathway in psychological stress-induced OT metastasis, suggesting a potential therapeutic target for intervention in OT metastasis.

Medical institutions, with their clinical practice foundation and abundant human use experience data, have become important carriers for the inheritance and innovation of traditional Chinese medicine(TCM) and the "cradles" of the preparation of new TCM. To effectively promote the transformation of new TCM originating from the TCM clinical practice in medical institutions and establish an effective evaluation index system for the transformation of new TCM conforming to the characteristics of TCM, consensus experts adopted the literature research, questionnaire survey, Delphi method, etc. By focusing on the policy and technical evaluation of new TCM originating from the TCM clinical practice in medical institutions, a comprehensive evaluation from the dimensions of drug safety, efficacy, feasibility, and characteristic advantages was conducted, thus forming a comprehensive evaluation system with four primary indicators and 37 secondary indicators. The expert consensus reached aims to encourage medical institutions at all levels to continuously improve the high-quality research and development and transformation of new TCM originating from the TCM clinical practice in medical institutions and targeted at clinical needs, so as to provide a decision-making basis for the preparation, selection, cultivation, and transformation of new TCM for medical institutions, improve the development efficiency of new TCM, and precisely respond to the public medication needs.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective:To investigate the clinical efficacy of pancreatic cancer surgery with arterial resection.Methods:The clinicopathological and follow-up data of 135 patients undergoing pancreatectomies with arterial resection in Pancreas Center, the First Affiliated Hospital of Nanjing Medical University from Sep 2013 to Dec 2023 were retrospectively analyzed.Results:There were 77 males and 58 females, with age [ M( IQR)] of 63 (14) years old. Among the 135 patients, 122 (90.4%) were distal pancreatectomies, 8 (5.9%) were pancreaticoduodenectomies, 4 (3.0%) were total pancreatectomies and 1 (0.7%) was resection for local recurrence after distal pancreatectomy. There were 120 (88.9%) celiac axis resections, 11 (8.1%) hepatic artery resections, 1 (0.7%) superior mesenteric artery resection and 3 (2.2%) other artery resections. Simultaneous portal vein-superior mesenteric vein or organ resection accounted for 26.7% (36/135) and 29.6% (40/135),respectively. The median blood loss was 300 (300) ml and the median operation time was 275 (105) minutes. The 90-day mortality rate was 7.4% (10/135). The overall morbidity rate was 70.4% (95/135) while the major morbidity rate was 18.5% (25/135). Postoperative hemorrhage occurred in 8.9% (12/135), clinically relevant postoperative pancreatic fistula in 57.0% (77/135), bile leak in 0.74% (1/135), delayed gastric emptying in 9.6% (13/135), liver failure in 3.7% (5/135) and transient liver enzyme elevation in 44.4% (60/135). All of the 135 cases were confirmed as pancreatic cancer histologically, including 54.6% (71/130) moderately differentiated, 45.4% (59/130) poorly differentiated and no for well differentiated. The median tumor size was 4.5 (2.3) cm.

Objective:To observe and analyze the correlation between the changes of macular microvascular structure and the level of intracocular fluid cytokines in patients with diabetic macular edema (DME).Methods:A prospective clinical study. From December 2022 to June 2024, 20 patients with 25 eyes of DME diagnosed by Department of Ophthalmology of Linyi People's Hospital were included in the study. Among them, 14 males had 17 eyes and 6 females had 8 eyes. Age was (55.08±10.34) years. Optical coherence tomography (OCT) and OCT angiography (OCTA) were used to scan the macular region at a range of 6 mm×6 mm. Central retinal thickness (CRT), blood flow density of superficial retinal capillary plexus (SCP) and area of fovea avascular zone (FAZ) were measured. The anterior aqueous humor was extracted before the first intravitreal injection of anti-vascular endothelial growth factor (VEGF), the concentrations of interleukin (IL-6), IL-8, VEGF, vascular cell adhesion molecule (VCAM), placental growth factor (PLGF) and monocyte chemotactic protein-1 (MCP-1) were detected. The correlation between macular microvascular structure and aqueous humor cytokines was analyzed by Spearman correlation analysis.Results:The CRT of the affected eyes was (617.40±167.64) μm, the SCP flow density was (39.56±1.55)%, and the FAZ area was (0.46±0.13) mm 2. The concentrations of IL-6, IL-8, VEGF, VCAM, PLGF and MCP-1 in aqueous humor were (301.36±690.52), (29.15±20.56), (71.37±29.32) and (5 621.22±7 241.06), (72.40±13.43), (464.07±163.26) pg/ml, respectively. Correlation analysis showed that there was a significant positive correlation between CRT and the concentrations of aqueous cytokines VEGF and PLGF ( r=0.460, 0.462, P<0.05). FAZ area was positively correlated with VEGF and MCP-1 concentrations ( r=0.414, 0.465; P<0.05). There was a significant negative correlation between SCP blood flow density and IL-6 ( r=0.401, P<0.05). Conclusion:There was a significant correlation between the morphological structure of macular area and the damage degree of microvessels around macular area in DME patients and the concentration of aqueous cytokines.

Objective:To explore the clinical effects of tibial periosteal distraction combined with antibiotic bone cement in treating diabetic foot ulcer.Methods:The study was a retrospective observational study. From March 2021 to March 2024, 52 patients with diabetic foot ulcers who met the inclusion criteria were admitted to Gansu Provincial People's Hospital, including 25 males and 27 females, aged 34-77 years. According to the treatment methods used by the patients, they were divided into control group (22 cases) treated with antibiotic bone cement alone and combined group (30 cases) treated with tibial periosteal distraction combined with antibiotic bone cement. Toe amputation rate, limb amputation rate, length of hospitalization, and ulcer healing time-consuming of patients were recorded. Before the first treatment and 3 weeks after the last treatment, the ankle skin temperature and ankle-brachial index of the affected foot were measured routinely, the pain of the affected foot was evaluated by using visual analog scale (VAS), and the peripheral nerve function of the affected foot was evaluated by 10 g nylon thread examination (denoted as 10 g nylon thread test value). Three weeks after the last treatment, the clinical efficacy of patients was evaluated and the overall rate of clinical efficacy was calculated.Results:There were no statistically significant differences in the comparison of toe amputation rate and limb amputation rate of patients in the 2 groups ( P>0.05). The length of hospitalization and ulcer healing time-consuming of patients in combined group were (23±5) and (41±6) d, respectively, which were significantly shorter than (27±5) and (46±6) d in control group (with t values of 3.08 and 3.18, respectively, both P values <0.05). The ankle skin temperature of the affected foot of patients in combined group was (34.1±1.5) ℃, and the ankle-brachial index was 0.72±0.08 three weeks after the last treatment, which were significantly higher than (32.1±1.6) ℃ and 0.58±0.09 before the first treatment within the group (with t values of 5.10 and 6.37, respectively, P<0.05) and (31.8±1.1) ℃ and 0.59±0.09 three weeks after the last treatment in control group (with t values of 6.88 and 5.49, respectively, P<0.05). The pain VAS score of the affected foot of patients in combined group 3 weeks after the last treatment was significantly lower than that before the first treatment within the group and 3 weeks after the last treatment in control group (with t values of 8.16 and 6.83, respectively, both P values <0.05), and the 10 g nylon thread test value was significantly higher than that before the first treatment within the group and 3 weeks after the last treatment in control group (with t values of 6.15 and 4.23, respectively, both P values <0.05). Three weeks after the last treatment, the overall rate of clinical efficacy of patients in combined group was 96.7% (29/30), which was significantly higher than 63.6% (14/22) in control group, χ2=7.51, P<0.05. Conclusions:Tibial periosteal distraction combined with antibiotic bone cement has good clinical effects in the treatment of diabetic foot ulcers. It can shorten the length of patients' hospitalization, promote the healing of the ulcers, reduce the pain in the affected foot, and improve the blood supply and peripheral nerve function in the affected foot.
