Objective To evaluate the effect of enteral nutritional support for the liver cancer patients with precise hepatetomy under fast track process model. Methods 82 patients were prospectively randomized into enteral nutrition group (n = 41) and parenteral nutrition (n = 41). The hemoglobin (HB), total protein (TP), albumin (ALB) and total lymphocyte count (TLC) were measured on 3 days before operation and 7 days after operation respectively. The two groups were compared in terms of time for anal exhaust and defecation after surgery , the postoperative hospital stay, the gastrointestinal adverse reactions and complications after surgery. Results The nutrition and immunity indicators on day 7 after operation were significantly poorer and lower than on day 3 before operation in the parenteral nutrition group (P<0.05); the declines of TP and ALB were significantly contained in the enteral nutrition group (P<0.05). The time for anal exhaust and defecation in the enteral nutrition group was advanced 15.1 h and 27.9 h on average, compared to the parenteral nutrition group and control group, respectively. The rate of adverse reaction was significantly lowered (17.3%vs. 40.4%, P<0.05). The rate of complications in the enteral nutrition group was significantly lower than the parenteral nutrition group (P>0.05). Conclusion Enteral nutritional support under fast track process model for the liver cancer patients undergoing precise resection could improve clinical outcome.

Objective To evaluate the efficacy of extended-field intensity-modulated radiotherapy (IMRT) in the treatment of patients with early-stage NK/T cell lymphoma (NKTCL),and to examine the clinical characteristics and the effect of treatment factors on the prognosis of these patients.Methods The clinical data of 165 patients with early-stage NKTCL who underwent extended-field IMRT with (n=158,95.8%) or without chemotherapy (n=7,4.2%) were reviewed.Of these 165 patients,140(84.8%) received a radiation dose of ≥50 Gy to the primary lesion,and 25 patients (15.2%) received a radiation dose of<50 Gy.Most patients (n=147,89.1%) were treated with L-asparaginase-based chemotherapy regimens,whereas only 11 patients (6.7%) were treated with doxorubicin-based CHOP/CHOP-like regimens.In addition,109 patients (66.1%) received ≥4 cycles of chemotherapy.Locoregional control (LRC),overall survival (OS),and progression-free survival (PFS) rates were calculated using the Kaplan-Meier method,and the log-rank test was used for survival comparison and univariate prognostic analysis.A multivariate prognostic analysis was performed using the Cox model.Results The 5-year sample size 55.The 5-year OS,PFS,and LRC rates of all patients were 74.2%,72.5%,84.4%,respectively.The patients who received a dose of ≥50 Gy had a significantly higher 5-year LRC rate than those with<50 Gy (91.8% vs.39.7%,P=0.000).The 5-year OS was significantly higher in the low-risk early-stage group than in the high-risk early-stage group (P=0.002).For the high-risk early-stage NKTCL group,patients who received ≥4 cycles of chemotherapy had significantly higher 5-year OS and PFS than those who received<4 cycles of chemotherapy (5-year OS:71.3% vs.59.5%,P=0.032;5-year PFS:70.4% vs.54.4%,P=0.009).In addition,multivariate analysis showed that ECOG≥2,primary tumor invasion (PTI),and Ann Arbor stage Ⅱ were associated with poor OS (P=0.006,0.002,0.014),and ECOG≥2 and PTI were associated with reduced LRC (P=0.004,0.016).Furthermore,ECOG≥2,PTI,Ann Arbor stage Ⅱ,and extranasal primary site were associated with lower PFS (P=0.045,0.003,0.030,0.032).Conclusions Extended-field IMRT at a dose of ≥50 Gy can lead to favorable LRC,OS,and PFS in patients with early-stage NKTCL.However,it is less effective against distant early-stage NKTCL in patients with poor prognosis.Nevertheless,≥4 cycles of chemotherapy can significantly improve the OS and PFS of patients with early-stage NKTCL.

Objective:To describe the real experience of the elderly who has felt happy during the time they stayed at nursing homes, and discuss the meaning which is behind their experience during the COVID-19 pandemic, to provide scientific basis for improving their subjective well-being.Methods:Qualitative explanatory phenomenological analysis methods, and semi-structured in-depth interviews were used to interview 21 elderly people living in Guangzhou Songhe Nursing Home. Data analysis and subject extraction were carried out with reference to the Colaizzi 7-step analysis.Results:The real experience of subjective well-being of the elderly in nursing homes has six themes: be satisfied with the nursing home management service, be satisfied with harmonious interpersonal relationship, be satisfied with good health, be satisfied with family support, grateful and expectations for the social support system, be satisfied with and grateful for the epidemic prevention work during the COVID-19 epidemic.Conclusions:The elderly who live in a nursing home with perfect management and service, care for each other, are healthy, receive family and social support, are grateful, and understand family and social support will be more likely to feel happy. Improving the subjective well-being of the elderly in nursing homes requires the coordination and support of nursing homes, the elderly, families, society and other aspects.

Objective To investigate the expression of pepsin in vocal cord polyps and vocal cord cancer,and to compare the difference of pepsin expression.Methods From May 2020 to December 2021,27 patients with vocal cord polyp,27 patients with vocal cord cancer and 23 healthy volunteers were selected.RSI and RFS scoring scales were used for scoring,pepsin detection kit was used for saliva pepsin detection,and immunohistochemical methods were used to detect the expression of pepsin in vocal cord tissues of patients with vocal cord polyps and vocal cord cancer.Results The RSI score,RFS score and pepsin test kit results of vocal cord polyp group and vocal cord canc-er group were higher than those of non-vocal cord disease group,and the differences of the three indexes were statis-tically significant(P<0.05).RSI score,pepsin detection kit results and pepsin immunohistochemistry results of vocal cord polyp group showed no significant difference compared with vocal cord cancer group(P>0.05).The RFS score of vocal cord polyp group was significantly different from that of vocal cord cancer group(P<0.05).Conclusion Pepsin may be an important pathogenic factor of vocal cord polyp and vocal cord cancer,and play an im-portant role in the occurrence of these two diseases.The difference of pepsin expression in vocal cord polyp and vo-cal cord cancer suggests that pepsin may have different pathogenesis.

Objective To investigate the antigen presentation characteristics of dendritic cells (DC) and B cells in cardiac grafts. Methods The heart of BALB/c mice was transplanted into the abdominal cavity of C57BL/6J mice. CD45+ cells in the heart graft were extracted and sorted by flow cytometry at postoperative 5 d, and single cell RNA sequencing was performed. Taking DC and B cell subsets in cardiac grafts as the main study cells, the changing trend, antigen presenting ability and intercellular communication with T cells after heart transplantation were analyzed by bioinformatics analysis and flow cytometry. Gene ontology (GO) function enrichment difference analysis was adopted to prove the specific function and the reliability annotation of cell subsets. Results Germinal center-like B cell (GC-L B) was the B cell subset with the largest increase in quantity during the acute rejection phase, accounting for 87%. Classical DC (cDC) 2 was the only DC subset with a significant increase in quantity during acute rejection of heart transplantation, accounting for 44% of DC subset, and it occupied the highest communication intensity with T cells after heart transplantation. Mononucleated DC (moDC) and memory B cell (MBC) were the main transmitters of T cell input signals in non-transplanted hearts, whereas transformed into cDC2 and GC-L B during the acute rejection phase. Among them, MBC and GC-L B were the main sources of T cell input signals in non-transplanted hearts and heart grafts. Conclusions Compared with DC, B cells occupy a higher number and weight in the intercellular communication with T cells in non-transplanted hearts and heart grafts, prompting that the antigen presenting activity of B cells is more active and stronger than DC in the early stage of acute rejection of heart transplantation.
