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.

Medical equipment is one of the important factors influencing medical services,and ensuring the integrity of medical equipment is an important part of hospital management,and the introduction of reliable medical equipment maintenance services can improve the quality of hospital medical management as a whole.Taking a tertiary hospital in Tianjin as an example,the study explores the subjective and objective evaluation indexes of clinical satisfaction after the introduction of maintenance serv-ices,builds a refined management system for medical equipment,and constantly adjusts the evaluation program of medical equip-ment maintenance services through the feedback mechanism,aiming to enhance the safety of the use of medical equipment,re-duce the cost of maintenance of medical equipment,and contribute to the high-quality development of the hospital.

Objective:To evaluate the efficacy and safety of the CLAE (cladribine + cytarabine + etoposide) regimen in refractory/relapsed T cell acute lymphoblastic leukemia/lymphoma (R/R T-ALL/LBL) .Methods:Patients with R/R T-ALL/LBL received the CLAE regimen in a prospective, multicenter, single-arm clinical study or compassionate use. From March 2019 to August 2024, data from 25 patients (18 in the study across five centers and 7 receiving compassionate treatment in Peking University Third Hospital) were collected. Outcomes included objective response rate, complete response (CR) rate, partial response (PR) rate after 1–2 cycles, bridging to allo-HSCT, progression-free survival (PFS), overall survival (OS), and treatment-related adverse effects.Results:Median age was 29 years (range, 13–63) ; 17 were male. Among the 24 evaluable patients, CR rate was 33.3% overall and 41.2% among enrolled patients. Median OS and PFS time were 199 (46–1 310) and 49 (28–1 310) days, respectively. Cumulative OS rate at 6 months, 1 year, and 2 years was (52.1±10.2) %, (29.7±9.3) %, and (27.1±9.1) %, respectively; cumulative PFS rate was (32.6±9.6) %, (24.9±8.9) %, and (23.8±8.7) %, respectively. Among patients achieving CR or PR (8 cases), median OS and PFS were not reached. Cumulative OS rate at 6 months, 1 year, and 2 years was (86.8±12.0) %, (78.3±14.6) %, and (72.9±15.7) %, respectively, and the cumulative PFS rate was (86.4±12.1) %, (74.8±15.3) %, and (72.9±15.7) %, respectively. Adverse events were mainly hematologic; no treatment-related mortality occurred. Seven patients achieving CR were bridged to allo-HSCT, with 5 remaining in continuous remission.Conclusion:The CLAE regimen is safe and effective for R/R T-ALL/LBL, facilitating CR as a bridge to allo-HSCT and potentially improving patient prognosis.

Objective:To compare the clinical effect of deproteinized calf blood extract (DCBE) eye drops and 0.3% sodium hyaluronate eye drops in the treatment of diabetic cataract patients with dry eye after phacoemulsification.Methods:A randomized controlled study was performed.A total of 112 patients (116 eyes) with type Ⅱ diabetes combined with cataract and dry eye who underwent phacoemulsification in the Eye Hospital of Shandong First Medical University from January 2022 to September 2022 were selected.Patients were divided into DCBE group (49 cases, 51 eyes) and sodium hyaluronate group (63 cases, 65 eyes) by the random number table method.Patients received DCBE eye drops and 0.3% sodium hyaluronate eye drops after surgery according to grouping.Preoperative and postoperative 1 week, 1 month subjective symptoms of dry eye, corneal edema grade, tear film breakup time (TBUT), corneal fluorescein staining (CFS) and Schirmer Ⅰ test (SⅠt) results were recorded and compared.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Eye Hospital of Shandong First Medical University (No.SDSYKYY202112-1).Written informed consent was obtained from each subject.Results:There were significant differences in dry eye symptom score, TBUT and SⅠt at different time points between before and after surgery ( Ftime=323.202, 102.771, 151.876; all P<0.001).Dry eye symptom score decreased and SⅠt increased in the two groups at 1 week and 1 month after surgery compared with before surgery, and the differences were statistically significant (all P<0.017).TBUT was longer at 1 week and 1 month after surgery compared with before surgery in the DCBE group, and TBUT at 1 month after surgery was longer than that before surgery in the sodium hyaluronate group, and the differences were statistically significant (all P<0.017).There were statistically significant differences in CFS scores between the two groups at different time points before and after surgery ( Fgroup=5.391, P=0.022; Ftime=142.402, P<0.001).The CFS scores of both groups at 1 week and 1 month after surgery were lower than those before surgery, and CFS scores in the DCBE group were lower than those in the sodium hyaluronate group, with statistically significant differences (all P<0.017).One week after surgery, the proportion of patients with corneal edema in the DCBE group was 5.9%(3/51), which was significantly lower than 20.0%(13/65) in the sodium hyaluronate group ( χ2=4.790, P=0.029). Conclusions:DCBE eye drops can promote corneal repair, stabilize tear film and improve dry eye discomfort in early postoperative period in diabetic cataract, and its overall effect is better than 0.3% sodium hyaluronate eye drops.

Objective:To investigate the long-term safety and effectiveness of stent implantation for residual pulmonary artery stenosis after complicated congenital heart disease.Methods:The symptoms, signs, echocardiography, cardiac CT, cardiac catheterization, six-minute walking distance, and BNP of 41 patients diagnosed from January 1996 to January 2020. In this group, 41 patients, 30 males and 11 females, aged 1.3-14.5 years old, mean (6.1±3.6) years old, and weighed 8-43 kg, mean (18.9±9.4)kg, compared the diameter of the target vessel, pressure difference across stenosis, cardiac function before and postoperative follow-up, and evaluated the long-term effect of stent implantation in the treatment of pulmonary artery stenosis.Results:All 41 patients were not lost to follow-up, no death, and there were no serious adverse events such as stent fracture, artery dissection and pulmonary embolism during follow-up. The median follow-up time was 7.1 years (3.1 to 13.8 years). As of January 2023, the echocardiographic results showed that the diameter of the target vessels in 41 patients increased from preoperative (3.9±1.5) mm to (6.0±1.5) mm ( P<0.05), the pressure difference across the stenosis decreased from preoperative (51.4±19.1) mmHg to (33.1±19.7) mmHg (1 mmHg=0.133 kPa, P<0.05); Heart spiral CT showed that the ratio of target vessel diameter to distal vessel diameter increased from preoperative 0.4±0.2 to 0.9±0.3( P<0.05). All patients had no slow growth and development, no recurrent lung infection, 39 patients (95.1%) had gradeⅠcardiac function, and 2 patients (4.9%) had gradeⅡcardiac function.As children in school age, the walking distance of 6 min was 462 to 633 m, mean( 529.9±57.1)m, the respiratory score was 0.5-1, and the lower limb force score was 6-12. There were 5 long-term adverse events, including 4 cases of target vessel restenosis (9.7%), and 1 case (2.4%), two of the patients with restenosis with repeated target vessel stenosis and lateral pulmonary hypertension were surgically intervention: stent removing and pumonary expanding, after 4, 13 years of stent implantation.And the others were still in follow-up, and no further intervention was made. The Cox multivariate survival analysis suggested that right ventricular systolic blood pressure was a risk factor for endpoint events before stent implantation ( P<0.05). Conclusion:The treatment of residual pulmonary artery stenosis after complicated congenital heart disease after percutaneous stent implantation can effectively relieve the right heart pressure overload, improve pulmonary blood flow, stabilize cardiac function, improve the long-term prognosis of patients with complicated congenital heart disease, reduce the chest opening rate of reoperation, and have stable long-term curative effect.
