Lung transplantation is the ultimate treatment for many kinds of end-stage lung diseases. However, the perioperative management of lung transplantation is complicated with high fatality of patients. Extracorporeal membrane oxygenation (ECMO) is an effective method of extracorporeal respiration and circulation support. ECMO plays an important role in the perioperative support treatment of lung transplantation, which breaks the limitation of contraindications and promotes the development of lung transplantation. In this article, the indications, catheter placement strategies and application of ECMO in the perioperative period of lung transplantation were reviewed.

BACKGROUND/AIMS: Kruppel-like factor 4 (KLF4) is an epithelial-specific transcription factor primarily expressed in the gastrointestinal tract that mediates growth arrest in the colonic epithelium. We tried to find whether KLF4 expression is associated with the progression and differentiation of colorectal cancer. METHODS: We detected KLF4 expression in 109 colorectal specimens (40 normal appearing mucosa, 7 adenomas, and 62 carcinomas) by immunohistochemistry using a tissue microarray. Western blot and RT-PCR analyses were also performed. RESULTS: The upregulation of KLF4 expression in carcinoma tissue was statistically significant (p<0.05) when compared to normal appearing mucosa. The negative and weak positive staining rates in normal appearing mucosa, adenoma, and carcinoma were 42.5%, 71.4%, and 82.3%, respectively, indicating a decreased degree of KLF4 expression over the course of progressive transformation of normal cells into malignant derivatives. KLF4 protein levels showed no correlation with sex, age, or metastatic state (p>0.05), while KLF4 protein expression correlated with the diagnostic stage (p<0.05). Furthermore, strong KLF4 staining was detected in 22.9% (11/48) and 0% (0/14) of well/moderately and poorly differentiated colorectal cancers, respectively. Our results clearly indicate that KLF4 protein expression significantly correlates with the degree of differentiation in colorectal cancers (p<0.05). KLF4 expression in RKO cells is also upregulated by butyrate, an inducer of differentiation. CONCLUSIONS: Downregulation of KLF4 expression may lead to more poorly differentiated tumors.

Objective:To develop the discrimination experience questionnaire for HIV/acquired immunodeficiency syndrome(AIDS) patients and test the reliability and validity of the questionnaire.Methods:Based on the literature review and semi-structured interviews to clarify the operational definition of discrimination for HIV/AIDS and develop the item pool. The questionnaire was developed though 2 rounds Delphi consultation and a pilot test. A total of 410 HIV/AIDS patients in Shanghai Public Health Clinical Center of Fudan University from June to December 2020 were selected to investigate the questionnaire, item analysis was used to screen items. SPSS 22.0 software was used for reliability test and exploratory factor analysis, the AMOS 21.0 software was used for confirmatory factor analysis to test the reliability and validity of the questionnaire.Results:The questionnaire consisted 2 dimensions(external discrimination and internal discrimination) and 10 items. Exploratory factor analysis showed that two common factors were extracted from the frequency of discrimination and the degree of negative psychological impact of discrimination experience on patients, and the cumulative variance contribution rates were 48.367% and 55.403%, respectively. The confirmatory factor analysis on the frequency of discrimination showed that Chi square degree of freedom ratio ( χ2/ df) was 2.831, P<0.05, root mean square of approximation error (RMSEA) was 0.093, goodness of fit index (GFI) was 0.928, comparative fit index (CFI) was 0.925, incremental fit index (IFI) was 0.926; the confirmatory factor analysis on the negative psychological impact of discrimination experience on patients showed that χ2/ df was 1.740, P<0.05; RMSEA was 0.076, GFI was 0.925, CFI was 0.936, IFI was 0.938. The content validity of the questionnaire was 0.9. The Cronbach α coefficientof questionnaire was 0.811, and the test-retest coefficient was 0.862 ( P<0.01). Conclusions:The discrimination experience questionnaire for HIV/AIDS patients has good reliability and validity, and it can be used to measure the discrimination for HIV/AIDS patients.

OBJECTIVE: To explore the association between single nucleotide polymorphism (SNPs) of KLK1 gene and cerebral hemorrhage in Changsha Han population. METHODS: We enrolled 273 patients with cerebral hemorrhage and 140 normal people. The SNPs (including rs3212855 and rs5515) of KLK1 gene were analyzed by Snapshot method and direct sequencing. RESULTS: We found rs5515 was not a polymorphic site in Changsha Han population. Genotype and allele frequency in rs3212855 were not different between patients with cerebral hemorrhage and the controls (P>0.05). The blood pressure level was not different between the genotype subgroups. CONCLUSION Neither rs5515 nor rs3212855 is associated with cerebral hemorrhage.

Objective:To construct a structured education course for patients with neurogenic bladder during the rehabilitation period.Methods:This study consisted three stages of current situation survey, literature search, and expert consultation. From February 2022 to February 2023, a current survey was conducted on the self-management needs of 62 patients with neurogenic bladder. In April 2023, a literature search was conducted to summarize the best evidence on nursing and management of neurogenic bladder, and form the initial version of course indicators and content. From April to May 2023, 14 experts were selected for consultation, and the Delphi method was used to demonstrate the course indicators and content, and to construct the final draft of the course.Results:A total of 62 patients with neurogenic bladder were included, they have requirements for water management, bladder function training, and dietary requirements, etc. A total of 2 053 articles were retrieved, and 14 articles were ultimately included, including eight guidelines, four evidence summaries, one expert consensus, and one systematic review. The expert authority coefficients for the two rounds of expert consultation were 0.93 and 0.92, respectively. The Kendall coordination coefficient of various indicators in the second round of expert consultation was 0.227 to 0.288 ( P<0.01). After two rounds of expert consultation, a structured education course for patients with neurogenic bladder during the rehabilitation period was finally developed, including six primary indicators, 21 secondary indicators, and 30 tertiary indicators. Conclusions:The structured education course for patients with neurogenic bladder during the rehabilitation period, based on current situation survey, high-quality evidence, and expert consultation, is comprehensive in content and reasonably designed, which can provide supportive assistance for future nursing health education and management for patients with neurogenic bladder.
