A total of 72 hospitalized patients with advanced colorectal cancer treated at the Department of Oncology, Nanjing Hospital of Traditional Chinese Medicine Affiliated to Nanjing University of Chinese Medicine from October 2022 to January 2024 were enrolled as study subjects. Using a random number table method, they were allocated into two groups, with 36 patients in each group. The control group received the mFOLFOX6/FOLFIRI combined with bevacizumab regimen, while the treatment group was administered additional oral Jianpi Bushen Jiedu Prescription on the basis of the control group. Two weeks was a cycle in both groups, with a total of 6 cycles of treatment. Serum levels of carcinoembryonic antigen (CEA), carbohydrate antigen 199 (CA199), and carbohydrate antigen 724 (CA724) were detected using electrochemiluminescence; the Karnofsky Performance Status (KPS) scale was utilized to evaluate patients' functional status; vital signs were continuously monitored, and adverse reactions were recorded. The short-term efficacy and TCM syndrome efficacy of patients were evaluated.Results:The treatment group demonstrated higher objective response rate (ORR) [31.25% (10/32) vs. 21.88% (7/32), χ2=0.72] and disease control rate (DCR) [84.38% (27/32) vs. 71.88% (23/32), χ2=1.46] compared to the control group, without statistical significance ( P>0.05). Post-treatment levels of CEA [4.09 (3.31,8.57) μg/L vs. 10.07 (4.55,22.35) μg/L, Z=-2.10] and CA72-4 [4.54 (2.04,10.99) mU/L vs. 9.48 (4.34,18.95) mU/L, Z=-2.52] in the treatment group were significantly lower than those in the control group ( P<0.05). The total effective rate of TCM syndrome was significantly higher in the treatment group [78.13% (25/32)] compared with the control group [50.00% (16/32)], with statistical significance ( χ2=5.50, P=0.019). Post-treatment KPS scores in the treatment group [80.0 (80.0, 80.0) vs. 70.0 (62.5, 80.0), Z=-2.76] were significantly higher compared with the control group ( P<0.01). During the treatment period, the treatment group showed statistical significance compared with the control group in the incidence of hemoglobin decrease ( χ2=4.66), leukopenia decrease ( χ2=4.27), and peripheral neuropathy ( χ2=3.93), with statistical significance ( P<0.05). Conclusion:The addition of Jianpi Bushen Jiedu Prescription to 5-FU-based chemotherapy combined with targeted therapy demonstrates significant clinical benefits in advanced colorectal cancer patients, including reducing tumor marker levels, alleviating clinical symptoms, improving quality of life, and mitigating treatment-related toxicities, with a good safety.

Objective:To explore the effect of EAERI (E: environment; A: accompany; E: emotion; R: respect; I: information) support strategies in the application of nurse second victims in restoring the passage of a patient safety incident, and to provide support to nurse second victims experiencing a safety incident in restoring the incident and mitigating secondary victimization from the incident.Methods:The method of historical comparison was adopted. A convenience sampling method was used to select nurses who experienced patient safety events in Shanxi Bethune Hospital (Shanxi Academy of Medical Sciences) from January 2023 to February 2024 as the study subjects, which were divided into observation group and control group by the historical control grouping method. The observation group used the EAERI support strategy for patient safety incident reduction, and the control group used the conventional reduction method. The second victims of the nurses in both groups were assessed for their level of harm and support in the patient safety incident using the Second Victim Experience and Support Tool before and after the event reduction, respectively.Results:A total of 124 second victims completed the study. There were 63 cases in the control group, including 13 males and 50 females, with an age of (30.24 ± 4.91) years old. There were 20 males and 41 females in the observation group, with an age of (30.85 ± 5.50) years old. Before the restoration event, there was no significant differences in the total scores of victim experience and support, the degree of injury and the degree of support between the two groups (all P>0.05). The total scores of victim experience and support, the degree of injury and the degree of support were (89.35 ± 10.69), (44.57 ± 6.19), (44.78 ± 9.40) points in the control group, and (64.13 ± 9.36), (33.56 ± 8.84), (30.56 ± 3.17) points in the observation group. The differences were significant between the two groups ( t=14.02, 8.07, 11.29, all P<0.01). Conclusions:The EAERI support strategy is feasible and effective. The implementation of the EAERI support strategy can reduce the degree of injury when the second victim of the nurse restores the safety incident and improve the degree of support.

Bronchopulmonary dysplasia (BPD), characterized by impaired alveolarization and dysregulated vascularization, is a severe health burden for neonates worldwide. Hyperoxia induced acute lung injury is a major contributor to the progression and deterioration of BPD. An increasing number of animal studies have revealed that human umbilical cord blood derived mononuclear cells (hUCB-MNCs) infusion significantly attenuated the hyperoxia-induced acute lung injury through regeneration capacity. Currently, clinical application requires determination of the optimal dose and adjustment to good manufacturing practices. In this work, we comprehensively investigated the optimal dose of hUCB-MNCs in alleviating hyperoxia-induced lung injury in neonatal C57BL6/J mice. Mice with hyperoxia exposure were implanted with low (3×104cells/kg, Dl), middle (3×105 cells/kg, Dm) and high (3×106 cells/kg, Dh) dose of hUCB-MNCs at postnatal day 7. Three weeks after graft, characteristics exhibited in lungs including morphology, function and cytokine expression were thoroughly analyzed. Implantation of hUCB-MNCs sharply reverted the impaired lung architecture induced by hyperoxia exposure dose dependently as evidenced by indicated parameters. Attenuated expression of IL-1β concomitant with enhanced expression of IL-10 and IL-2 were shown in Dh inoculated groups, where Dl and Dm failed to restore the level of IL-10, IL-1β and IL-2. Significantly re-escalated marker of angiogenic marker VEGFA, CD31 in lung tissue were uniquely observed in Dh group. Mechanistically, our study revealed the appropriate dose of intravenous infusion of hUCB-MNCs in alleviating hyperoxia-induced lung injury through modulating reactive oxygen species response in neonatal mice.Therefore, a tight control of hUCB-MNCs density or levels of CB-MNC related products is of great significance.

Objective:To explore the effect of family empowerment model on the improvement of swallowing care ability and care preparedness of primary caregivers of first-episode stroke dysphagia patients, further to explore its impact on patients′s wallowing function and life quality.Methods:This study was a randomized controlled study. From January 2021 to December 2022, 80 main caregivers of patients with dysphagia caused by manual stroke admitted to the Department of Acupuncture and Moxibustion, Shenzhen Hospital of Traditional Chinese Medicine were selected as the research objects, and 40 cases in the control group and 40 cases in the observation group were selected by random number table method. The control group were treated with conventional nursing care of first-episode stroke dysphagia patients in the acupuncture and moxibustion Department. On the basis of the conventional care in the control group, the observation group were treated with family empowerment model intervention for 14 days and was followed up for 28 days. Primary caregivers′ swallowing care ability, Caregiver Preparedness Scale (CPS), patients′ swallowing function rate, Swallowing Related Quality of Life (SWALQOL) were used to evaluate the effects before intervention and at the end of intervention.Results:There were 18 males and 19 females primary caregivers in the control group, aged (55.61 ± 7.43) years old. There were 18 males and 21 females primary caregivers in the observation group, aged (58.23 ± 8.22) years old. The swallowing care ability score showed a statistically significant difference between the observation group (143.47 ± 3.96) and the control group (107.74 ± 1.43) ( t=-26.76, P<0.05). After intervention, the caregiver preparedness scale was (26.11 ± 3.81) in the observation group, and (18.35 ± 4.54) in the control group, and the difference was statistically significant ( t=-4.11, P<0.05).The patients′ swallowing function rate and SWALQOL score were respectively 97.44% (38/39) and (91.41 ± 8.08) points in the observation group, and 72.97% (27/37) and (80.33 ± 4.21) points in the control group, and the difference was both statistically significant ( χ2=10.76, t=-2.54, both P<0.05). Conclusions:The implementation of family empowerment model could enhance the swallowing care ability and care preparedness of primary caregivers of the first-episode stroke dysphagia patients, which could further improve patients′ swallowing function and life quality.

Ferrets offer an advantage in nonclinical studies of anti-infective drugs because of their ability to be infected with and spread pathogenic microorganisms,especially viral strains,without the need for host adaptation.Additionally,the clinical symptoms exhibited by infected ferrets are very similar to those of humans.Although ferrets play a very important role in the research and development of antiviral drugs,the scope of their application remains limited.This may be related to the lack of corresponding national standards for laboratory animal feeding and application of ferrets as well as the lack of specific diagnostic and detection reagents.This paper summarizes the characteristics of ferrets as infectious disease models with a summary and analysis of the application direction of ferrets in anti-infective drug research.Our aim is to promote further standardization of the use of ferrets.

【Objective】 To investigate the expression of optineurin (OPTN) in multiple myeloma (MM) and explore the mechanism and clinical value of OPTN gene in the occurrence and development of MM. 【Methods】 In this study, three gene expression omnibus (GEO) data sets were used to analyze the expression level of OPTN in MM. Clinical bone marrow samples of MM patients were collected. qRT-PCR was used to further verify the expression of OPTN in MM patients. The Kaplan-Meier survival curve and receiver operating characteristic (ROC) curve were used to analyze the value of OPTN in the prognosis and diagnosis of MM. At the same time, MM transcriptome data were downloaded from the Cancer Genome Atlas (TCGA) database. According to the median boundary of OPTN mRNA expression level, the MM patients were divided into OPTN high- and low-expression groups. In order to investigate the possible molecular mechanisms of OPTN in MM, gene set enrichment analysis (GSEA) was made after the differentially expressed genes were filtered using the limma package of the R language. 【Results】 The expression level of OPTN was significantly lower in MM tissues than in normal tissues (P<0.05). OPTN expression level was significantly correlated with International Staging System (ISS) in MM patients (P<0.05). ROC results showed that the expression level of OPTN could distinguish between normal and MM patients. Survival analysis showed that the overall survival (OS) of patients with low OPTN expression was significantly lower than that of patients with high OPTN expression (P<0.05). GO, KEGG and GSEA enrichment analyses indicated that OPTN might affect apoptosis and autophagy, and regulate cellular immune response by regulating Nod-like receptors, NF-κB, TNF and RAS/MAPK pathways. 【Conclusion】 Low expression of OPTN in MM is associated with poor prognosis of patients, and thus may be an important potential biomarker for the diagnosis and treatment of MM.
