Objective:To evaluate the safety and efficacy of sequential consolidation thoracic radiotherapy after first-line chemotherapy combined with immunotherapy for extensive-stage small cell lung cancer (SCLC).Methods:A retrospective analysis of patients with extensive-stage SCLC admitted to Jiangsu Cancer Hospital from January 2019 to September 2022 was conducted. Patients who achieved effective chemotherapy combined with immunotherapy received sequential consolidation thoracic radiotherapy. The safety was evaluated according to the common terminology criteria for adverse events (CTCAE) 5.0 standard, and the overall survival (OS) and progression-free survival (PFS) were analyzed by Kaplan-Meier method.Results:A total of 33 patients were enrolled, with a median age of 66 years (range, 50-79 years). The median follow-up time was 20 months (range, 3-33 months). Fifteen patients (46%) had disease progression, and 12 patients (36%) died. The toxicities mainly included leukopenia, thrombocytopenia, radiation esophagitis, anorexia, and fatigue, etc. Six patients (18%) had grade 4 hematological toxicity, mainly leukopenia. One patient (3%) had grade 3 radiation pneumonitis, and 3 patients (9%) had grade 1-2 radiation pneumonitis. No grade 5 toxicity was observed in all patient groups. The median PFS was 12 months (95% CI=3.9-20.1). The 6-month, 1-year, and 2-year PFS rates were 78%, 49.6%, and 35.6%, respectively. The median OS was 23 months (95% CI=15.98-30.01). The 6-month, 1-year, and 2-year OS rates were 86.2%, 74.5%, and 47.2%, respectively. Conclusions:Sequential consolidation thoracic radiotherapy after first-line chemotherapy combined with immunotherapy is a safe protocol for extensive-stage SCLC. It brings survival benefits to patients by increasing PFS and OS rates.

BACKGROUND:
Breast cancer patients who are positive for hormone receptor typically exhibit a favorable prognosis. It is controversial whether chemotherapy is necessary for them after surgery. Our study aimed to establish a multigene model to predict the relapse of hormone receptor-positive early-stage Chinese breast cancer after surgery and direct individualized application of chemotherapy in breast cancer patients after surgery.
METHODS:
In this study, differentially expressed genes (DEGs) were identified between relapse and nonrelapse breast cancer groups based on RNA sequencing. Gene set enrichment analysis (GSEA) was performed to identify potential relapse-relevant pathways. CIBERSORT and Microenvironment Cell Populations-counter algorithms were used to analyze immune infiltration. The least absolute shrinkage and selection operator (LASSO) regression, log-rank tests, and multiple Cox regression were performed to identify prognostic signatures. A predictive model was developed and validated based on Kaplan-Meier analysis, receiver operating characteristic curve (ROC).
RESULTS:
A total of 234 out of 487 patients were enrolled in this study, and 1588 DEGs were identified between the relapse and nonrelapse groups. GSEA results showed that immune-related pathways were enriched in the nonrelapse group, whereas cell cycle- and metabolism-relevant pathways were enriched in the relapse group. A predictive model was developed using three genes ( CKMT1B , SMR3B , and OR11M1P ) generated from the LASSO regression. The model stratified breast cancer patients into high- and low-risk subgroups with significantly different prognostic statuses, and our model was independent of other clinical factors. Time-dependent ROC showed high predictive performance of the model.
CONCLUSIONS
A multigene model was established from RNA-sequencing data to direct risk classification and predict relapse of hormone receptor-positive breast cancer in Chinese patients. Utilization of the model could provide individualized evaluation of chemotherapy after surgery for breast cancer patients.

Objective To evaluate the development, hot spots and trends of the fields of neurogenic bladder.Methods The relevant articles of neurogenic bladder from January, 2000 to June, 2021 in CNKI and Web of Science were retrieved.The countries, authors, institutions, cited reference and keywords were extracted with CiteSpace to draw knowledge mapping. Results and Conclusion A total of 5 064 articles were enrolled. At present, the research on the field of neurogenic bladder is in a stable period of development, and this field has been widely concerned by scholars at home and abroad. The cooperation between domestic authors and institutions is not close enough compared with foreign countries, and domestic cooperation is more between medical schools and their respective affiliated hospitals. In the future, China can further strengthen cross-regional and cross-agency cooperation. Low-frequency electrical stimulation and sacral nerve regulation are seem to be research hotspots, and children's neurogenic bladder and robot-assisted technologies are also needed more attention.

PURPOSE: Follistatin-like protein 1 (FSTL1) is a secreted glycoprotein that has been shown to play a role in various types of cancer. However, the clinical significance and function of FSTL1 in breast cancer have not been reported. We investigated the role of FSTL1 in breast cancer in this study. METHODS: Enzyme-linked immunosorbent assays, western blot analysis, and reverse transcription polymerase chain reaction were used to monitor the expression of FSTL1 in breast cancer tissue and in serum samples from breast cancer patients. We employed a 4T1 breast cancer model and Fstl1(+/−) mice for in vivo studies. Hematoxylin and eosin staining, western blot analysis, and RNA sequencing were used to analyze the effect of FSTL1 on primary tumor growth and lung metastasis. RESULTS: We demonstrated that the expression of FSTL1 is reduced in both the breast cancer tissue and the serum of breast cancer patients. We showed that reduced levels of FSTL1 in serum correlate with elevated expression of Ki-67 and epidermal growth factor receptor (EGFR) in cancer tissues. Moreover, lowered expression of FSTL1 was associated with decreased survival in breast cancer patients. Experiments on the Fstl1(+/−) mouse model established that FSTL1 deficiency had no effect on primary tumor growth, but increased the lung metastases of breast cancer cells, resulting in reduced survival of tumor-bearing mice. RNA sequencing found significantly reduced expression of Egln3 and increased expression of EGFR in Fstl1(+/−) mice. Thus, our results suggest that FSTL1 may affect the expression of EGFR through Egln3, inhibiting the proliferation of breast cancer cells at lung metastatic sites. CONCLUSION: In conclusion, we suggest a suppressor role of FSTL1 in breast cancer lung metastasis. Furthermore, FSTL1 may represent a potential prognostic biomarker and a candidate therapeutic target in breast cancer patients.

Objective To investigate the relationships between occupational coping self-efficacy, job stress and core competence of nurses. Methods A total of 493 registered nurses were recruited in the survey with the Chinese nurse job stressors scale, occupational coping self-efficacy scale for nurses and competency inventory for registered nurse (CIRN). The correlations were analyzed using Pearson correlation analysis. Results The total scores on occupational coping self-efficacy, job stress of nurses and core competence of nurses were (31.94 ± 6.39), (90.29 ± 17.41) and (159.93 ± 34.31), respectively. Nurses′occupational coping self-efficacy negatively correlated with (r=-0.267, P<0.01) and positively correlated with the core competence of nurses (r=0.355, P<0.01). Conclusions The occupational coping self-efficacy of the nurses can be improved by successful experiencing, verbal persuasion and positive feedback. In this way, nurses core competence can be enhanced and their job stress can be relieved and consequently the quality of nursing can be enhanced.
