Esophageal cancer is a prevalent malignant tumor of the digestive tract in China, and radical surgery remains the cornerstone of its comprehensive treatment. However, multifactorial challenges such as postoperative gastrointestinal tract reconstruction, traumatic stress, and tumor-related metabolic disturbances render esophageal cancer patients highly susceptible to malnutrition. Perioperative nutritional support therapy plays a crucial role in enhancing surgical safety, improving clinical outcomes, and elevating patients' quality of life by regulating metabolic homeostasis, preserving organ function, and optimizing the immune microenvironment. This article reviews the mechanisms underlying malnutrition in esophageal cancer, methods for nutritional status assessment, and precision intervention pathways based on multi-omics evaluations. The aim is to strengthen clinicians' awareness of standardized perioperative nutritional management for esophageal cancer patients and promote its clinical implementation, thereby facilitating postoperative recovery and improving long-term quality of life.

Objective:To examine the validity and reliability of the Chinese version of the Transgender Atti-tudes and Beliefs Scale(TABS)in the general adult population.Methods:A total of 1 656 residents aged≥18 years were recruited by convenient sampling method,and were equally divided into sample 1 and sample 2 accord-ing to age group.The total sample was used for item analysis and internal consistency reliability test.Sample 1 was used for exploratory factor analysis,Sample 2 was used for confirmatory factor analysis,and 60 residents were se-lected for retesting at a 2-week interval.Results:The TABS Chinese version included a total of 26 items,with the content validity index(I-CVI)of each item ranging from 0.83 to 1.00,and the content validity index(S-CVI)of the scale being 0.98.Exploratory factor analysis extracted 3 common factors,namely interpersonal comfort,gender beliefs,and human value,with a cumulative total variance of 57.13％.Confirmatory factor analysis showed that the scale fit was acceptable(x2/df=2.95,RMSEA=0.05,GFI=0.92,AGFI=0.90).The Cronbach α coefficients of the total score of the scale and the scores of the 3 factors were 0.95,0.95,0.88 and 0.86.The retest reliabilities were 0.88,0.78,0.65 and 0.91.Conclusion:The Chinese version of the Transgender Attitudes and Beliefs Scale(TABS)has good validity and reliability in assessing general adults'attitudes toward the transgender community.

AIM:To study the effect of Sanhuang Gel on the expression of TLRs/NLRP3 signal path-way in auricle acne model rats,and to explore its mechanism in treating acne inflammatory injury.METHODS:A rat model of auricular acne was in-duced by applying 100％oleic acid to the opening of the right ear catheter and injecting Propionibac-terium acnes.Rats were divided into normal group,model group,positive control group(clindamycin hydrochloride gel 10 mg/g)and Sanhuang Gel high,medium and low dose groups(280,140 and 70 mg/g).Each drug group was given drug intervention for 28 days.The changes of auricle skin lesions in each group were observed;Hematoxylin-eosin(HE)staining was used to observe the pathological changes of auricle acne.The ultrastructural chang-es of auricle tissue cells were observed by transmis-sion electron microscope(TEM).The distribution and expression changes of TLR2 and TLR4 in rat au-ricle tissue were detected by immunofluorescence.The expressions of TLR2,TLR4,NLRP3,ASC and Cas-pase-1 mRNA in rat auricle were detected by Real-time PCR.The expressions of TLR2,TLR4,NLRP3,ASC and Caspase-1 in rat auricle were detected by Western blot.RESULTS:Compared with the normal group,papules,pustules,inflammatory cell infiltra-tion and obvious edema of mitochondria can be seen in the auricle tissue of the model group.The mRNA and protein expression levels of TLR2,TLR4,NLRP3,ASC andCaspase-1 increased significantly(P＜0.01).Compared with the model group,the ap-pearance and pathological damage of auricle in each treatment group were obviously alleviated,and the morphology and structure of mitochondria returned to normal.The mRNA expression levels of TLR2,TLR4,NLRP3,ASC and Caspase-1 decreased significantly(P＜0.01).The expression levels of TLR2,TLR4,NLRP3,ASC and Caspase-1 in positive control group and high and middle dose groups de-creased(P＜0.01,P＜0.05).The expression levels of ASC and Caspase-1 protein in low dose group were significantly decreased(P＜0.01),but there was no significant difference in the expression levels of TLR2,TLR4 and NLRP3 protein(P＞0.05).CONCLU-SION:Sanhuang Gel can improve the pathological damage of auricle tissue and reduce immune in-flammatory reaction in acne rats,and its mecha-nism may be related to regulating TLRs/NLRP3 sig-naling pathway.

Objective:To investigate the level of rehabilitation exercise adherence in patients undergoing anterior cruciate ligament (ACL) reconstruction within 6 months post-surgery, analyze its trajectory, and provide a reference for clinical nursing interventions.Methods:Using a convenience sampling method, 150 patients who underwent arthroscopic ACL reconstruction at the First Affiliated Hospital of Zhengzhou University from June 2022 to August 2023 were selected. Rehabilitation exercise adherence was assessed monthly from postoperative 1 month (M 1) to 6 months (M 6) using the Orthopedic Functional Exercise Adherence Scale. A latent class growth model was employed to analyze adherence trajectory categories, and Logistic regression was used to identify influencing factors for different adherence trajectories. Results:A total of 144 patients completed follow-up (follow-up rate was 96.00%). Exercise adherence scores gradually declined over the 6 months post-surgery, with scores of (50.30±5.39), (45.92±3.85), (39.48±5.27), (35.83±6.19), (31.85±7.59), and (29.88±7.88) from M 1 to M 6, respectively. The difference in scores across time points was statistically significant ( F=85.467, P<0.01). Three potential categories were identified through the latent class growth model: the moderate-high level rapid decline group ( n=65, 45.14%), the moderate-low level stable group ( n=32, 22.22%), and the moderate-low level slow decline group ( n=47, 32.64%). Logistic regression analysis revealed that gender and age were significant factors influencing adherence trajectory categories ( P<0.05) . Conclusions:Dynamic declines in rehabilitation exercise adherence are common among ACL reconstruction patients, with varying degrees of decline. Gender and age may influence adherence trajectories, suggesting that targeted management strategies could be implemented in clinical practice.

OBJECITVE: To investigate the effectiveness of three-dimensional (3D) printing-assisted vascularized fibular graft for repairing metatarsal defects. METHODS: Between November 2021 and February 2024, 11 patients with varying degrees of metatarsal defects caused by trauma were treated. There were 10 males and 1 female, aged 22-67 years, with a mean age of 51.2 years. The defect locations were as follows: the first metatarsal in 4 cases, the fifth metatarsal in 2 cases, the first and the second metatarsals in 1 case, the first to third metatarsals in 1 case, the third and the fourth metatarsals in 1 case, the third to fifth metatarsals in 1 case, and the first to fifth metatarsals in 1 case. The preoperative American Orthopaedic Foot & Ankle Society (AOFAS) score was 67.0 (48.5, 72.5). Based on 3D-printed bilateral feet models and mirrored healthy-side foot arch angles for preoperative planning and design, the vascularized fibular graft was performed to repair the metatarsal defects. At last follow-up, the medial and lateral longitudinal arches of bilateral feet were measured on weight-bearing X-ray films, and functional assessment was conducted using the AOFAS score. RESULTS: All operations were successfully completed, with an operation time ranging from 180 to 465 minutes (mean, 246.8 minutes). All incisions healed by first intention, with no occurrence of osteomyelitis. All patients were followed up 6-22 months (mean, 10 months). X-ray film reviews showed bone graft healing in all cases, with a healing time of 3-6 months (mean, 5 months). All patients underwent internal fixator removal at 6-12 months after operation. At last follow-up, no significant difference was observed in the medial and lateral longitudinal arches between the healthy and affected feet ( P>0.05). The AOFAS score of the affected foot was 78.0 (73.5, 84.0), showing a significant improvement compared to the preoperative score ( P<0.05). The effectiveness was rated as excellent in 1 case, good in 7 cases, fair in 2 cases, and poor in 1 case. Linear scarring remained at the donor site, with no functional impairment in adjacent joint movement. CONCLUSION 3D printing-assisted vascularized fibular graft for repairing metatarsal defects can effectively restore the physiological angle of the foot arch, facilitate the recovery of weight-bearing alignment, promote good bone healing, and yield satisfactory clinical outcomes.

Efferocytosis refers to the process of phagocytes engulfing and clearing the cells after programmed cell death. In recent years, an increasing number of studies have shown that the mechanisms of efferocytosis are closely related to drug-induced liver injury, hepatic ischemia-reperfusion injury, viral hepatitis, cholestatic liver diseases, metabolic-associated fatty liver disease, alcoholic liver disease, and other liver disorders. This review summarized the research progress on the role of efferocytosis in liver diseases, with the hope of providing new targets for the prevention and treatment of liver diseases.

Objective:To explore the movement patterns and factors influencing lung tumors tracked using the M6 cyberknife stereotactic radiotherapy(SRT)system and to provide a reference for the implementation of precise stereotactic radiotherapy for lung tumors.Method:A retrospective analysis was conducted on 29 patients with lung tumors who were treated using x-sight lung tracking technology and the M6 cyberknife SRT system at Tianjin Medical University Cancer Institute&Hospital,from January 2022 to August 2024.The tumor location and volume,irradiation dose,isodose line,and number of divisions were recorded.Lung tumor location and SPSS 26.0 software were used to analyze the movement amplitude of tumors in the left and right(LFT/RGT,LR)directions,the anterior-posterior(ANT/POS,AP)direction,and the superior-inferior(SUP/INF,SI)direction.The results are expressed as the mean±standard deviation((x)±s)mm,and a t-test was used for inter-group comparisons.Multiple linear regression was used to analyze the effects of factors such as age,gender,tumor location(upper and lower lungs),and tumor volume on the amplitudes of the lung tumor movements.Result:The average motion amplitudes in the LR direc-tions,AP direction,and SI direction of the tumor target areas were(3.5±1.8)mm,(5.3±1.7)mm,and(7.3±5.4)mm for the upper lung,based on 19 cases,and(3.1±1.6)mm,(4.5±2.2)mm,and(12.2±4.4)mm for the lower lung,based on 10 cases,respectively.There was a statistic-ally significant difference(P=0.015 3)in the amplitude of movements between the lower and upper lung tumors in the SI direction.The lung tumor movement amplitude in the SI direction was influenced by tumor location(P=0.035),and the movement amplitudes in the LR direc-tions and the AP direction were not related to factors such as gender,age,tumor location,and tumor volume.Conclusions:The lung tumor movement amplitudes for the different locations varied depending on the respiratory movement shown by the patient.In the SI direction,the movement amplitude of the lower lung tumors was greater than that of upper lung tumors,and this was due to tumor location effects.The movement amplitudes of the lower and upper lung tumors were similar in the LR directions and AP directions.Furthermore,movement amplitude was not affected by gender,age,tumor location,and tumor volume.

Nonunion of osteoporotic vertebral fractures (OVF), predominantly affecting the elderly, can lead to intractable pain, vertebral collapse, progressive kyphotic deformity, and neurological impairment, significantly compromising patients′ quality of life. There exists considerable debate on diagnosis and management of OVF, encompassing key issues such as clinical diagnosis and staging criteria for nonunion, surgical indications and procedure selection, and postoperative rehabilitation planning. Currently, there lacks standardized clinical guideline and expert consensus on the diagnosis and management of OVF nonunion in China. To address this gap, Minimally Invasive Surgery Group of Chinese Orthopedic Association, Osteoporosis Committee of Chinese Association of Orthopedic Surgeons, Prevention and Rehabilitation Committee for Osteoporosis of Chinese Association of Rehabilitation Medicine and Minimally Invasive Orthopedic Surgery Branch of China Association for Geriatric Care jointly organized domestic experts in spinal surgery, endocrinology, and rehabilitation to formulate the Clinical guideline for the diagnosis and treatment for nonunion of osteoporotic vertebral fractures ( version 2025), based on existing literature and clinical experience and adhering to principles of scientific rigor and practicality. The guideline provided 13 evidence-based recommendations encompassing diagnosis and treatment of OVF nonunion, aiming to standardize its clinical management.
