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 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 investigate the effect of luteinizing hormone (LH) levels on the clinical outcome and cumulative live birth rate of in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) fresh embryo transfer in patients with normal ovarian reserve function after application of a flexible protocol of gonadotropin-releasing hormone antagonist (GnRH-A) to promote ovulation with the addition of GnRH-A. Methods:A retrospective cohort study was conducted to analyze the data of 685 patients with normal ovarian reserve function who underwent IVF/ICSI after ovulation induction with antagonist flexible regimen between January 2016 and June 2021 at the Reproductive Medicine Center of the Third Affiliated Hospital of Zhengzhou University. The quartile method was used to group patients after the addition of the antagonist by the mean value of serum LH each time they were monitored (usually twice, depending on the rate of follicular growth and patients' need) until the day of the trigger, and were divided into group A (smaller than the 25th percentile of the mean LH level of the included population, LH<1.25 U/L, n=166), group B (in the 25th to 50th percentile of the mean LH level of the included population, 1.25 U/L≤LH<1.91 U/L, n=174), group C (in the 50th to 75th percentile of the mean LH level of the included population, 1.91 U/L≤LH<2.85 U/L, n=171), and group D (greater than the 75th percentile of the mean LH level of the included population, 2.85 U/L≤LH≤7.55 U/L, n=174). The general condition, clinical data, embryo laboratory indices, clinical outcome indices of fresh embryo transfer cycle and cumulative live birth rate were compared among the 4 groups. Results:After correcting for confounding factors by multifactorial linear regression, the number of high-quality embryos and the rate of blastocyst formation of patients in group C were significantly higher than those in group A, and the differences were statistically significant ( B=0.600, 95% CI: 0.086-1.114, P=0.022; B=0.134, 95% CI: 0.052-0.216, P=0.001). The number of high-quality embryos, the number of available embryos, and the rate of blastocyst formation of patients in group D were significantly higher than those in group A, and the differences were statistically significant ( B=0.771, 95% CI: 0.259-1.284, P=0.003; B=0.730, 95% CI: 0.205-1.255, P=0.007; B=0.085, 95% CI: 0.003-0.167, P=0.042).After multifactorial logistic regression, there was no statistically significant difference in live birth rate between group A and groups B, C and D ( P>0.05). The cumulative live birth rate of patients in group D was significantly higher than that in group A, and the difference was statistically significant ( aOR=2.439, 95% CI: 1.169-4.974, P=0.014). Conclusion:In patients with normal ovarian reserve function, a flexible protocol of antagonists was applied to promote ovulation, and the addition of antagonists had no significant effect on the clinical outcome of the fresh embryo transfer cycle in terms of mean LH levels, but the quality of the embryos was significantly reduced when the mean LH level was <1.25 U/L, and this may consequently reduce the developmental potential of the embryos and the cumulative live birth rate.

OBJECTIVE: To understand the mental health status of subway employees, and to explore the relationship among their mental health, psychological capital and work engagement. METHODS: Using the typical sampling method, a total of 2 758 subway employees from a rail transit group Co., Ltd in a city were selected as the study subjects. The Symptom Check List 90, Psychological Capital Questionnaire, and Utrecht Work Engagement Scale were used to investigate the mental health, psychological capital and work engagement of the study subjects. RESULTS: The screening positive rate of mental disorder of the study subjects was 15.6%(431/2 758), and the median scores of mental health, psychological capital, and work engagement were 108, 109, and 62 points, respectively. The mental health scores of the study subjects were negatively correlated with their psychological capital and work engagement scores [Spearman correlation coefficient(r_S) were-0.55 and-0.57, respectively, P<0.01]. The psychological capital score was positively correlated with the work engagement score(r_S=0.70, P<0.01).Mental health played a partial mediating role in the influence of psychological capital on work engagement(mediating effect was 0.07, 95% correlation coefficient: 0.06-0.08, P<0.01). CONCLUSION: The mental health status of the subway employees is good. Psychological capital of subway employees can not only directly affect work engagement, but also indirectly affect work engagement by influencing mental health.

Although high-efficiency targeted delivery is investigated for years, the efficiency of tumor targeting seems still a hard core to smash. To overcome this problem, we design a three-step delivery strategy based on streptavidin-biotin interaction with the help of c(RGDfK), magnetic fields and lasers. The ultrasmall superparamagnetic iron oxide nanoparticles (USIONPs) modified with c(RGDfK) and biotin are delivered at step 1, followed by streptavidin and the doxorubicin (Dox) loaded nanosystems conjugated with biotin at steps 2 and 3, respectively. The delivery systems were proved to be efficient on A549 cells. The co-localization of signal for each step revealed the targeting mechanism. The external magnetic field could further amplify the endocytosis of USPIONs based on c(RGDfK), and magnify the uptake distinctions among different test groups. Based on photoacoustic imaging, laser-heating treatment could enhance the permeability of tumor venous blood vessels and change the insufficient blood flow in cancer. Then, it was noticed that only three-step delivery with laser-heating and magnetic fields realized the highest tumor distribution of nanosystem. Finally, the magnetism/laser-auxiliary cascaded delivery exhibited the best antitumor efficacy. Generally, this study demonstrated the necessity of combining physical, biological and chemical means of targeting.

Objective:To explore surgical techniques and summarize surgical experience of the paraumbilical flap pedicled with deep inferior epigastric vessels for the repiration of soft tissue defects in pelvic area.Methods:Between August, 2006 and August, 2018, 8 patients with soft tissue defects and bone exposure were treated with paraumbilical flap pedicled with deep inferior epigastric vessels. There were 6 males and 2 females with the average age of 35.3 (range, 12-47) years. The defects were caused by car accident in 5 cases, by high falling injury in 1 case, by soft tissue necrosis after malignant schwannoma resection in 1 case, and by soft tissue necrosis after pelvic operation of open reduction internal fixation in 1 case. The defects located at iliac spine in 5 cases, at tuber ischii in 1 case, and at buttock and perineal region in 1 case. The size of the wounds ranged from 11.0 cm×6.0 cm to 22.0 cm×8.0 cm. The size of the flaps ranged from 13.0 cm×7.0 cm to 29.0 cm×12.0 cm. The followed-up was made by outpatinet service, telephone or WeChat.Results:All flaps survived, and the wound infection was controlled. The followed-up time ranged from 12 to 46 (mean 26) months. All flaps survived uneventfully, and the texture and elasticity of the flaps were good. There were no recurrence of infection, and no ventral hernias occurred in donor sites.Conclusion:The transfer of paraumbilical flap pedicled with deep inferior epigastric vessels is a reliable method to repair large soft tissue defects in iliac spine, perineal region, buttock and tuber ischii.
