Objective:To retrieve, evaluate, and summarize the evidence on fertility management for cervical cancer patients of childbearing age, providing a basis for clinical medical and nursing staff to carry out fertility management for cervical cancer patients.Methods:The evidence on fertility in cervical cancer patients included clinical decision-making, guidelines, summary of evidence, expert consensus, and systematic review, which were systematically searched on domestic and international evidence-based medicine databases, clinical decision-making systems, guideline websites, professional association websites, medical literature service websites, and databases such as UpToDate, Cochrane Library, British Medical Journal (BMJ) Best Practice, China Guidelines Network, China National Knowledge Infrastructure, WanFang Med Online, China Biology Medicine disc, and VIP. The search period was from database establishment to March 1, 2023. Two researchers who received evidence-based nursing knowledge training independently conducted literature screening and quality evaluation, and jointly discussed with clinical experts on the literature that met the requirements to complete evidence extraction and summary.Results:A total of 11 articles were included, including three clinical decision-making, four guidelines, three expert consensus, and one systematic review. A total of 30 pieces of best evidence were summarized from six aspects, including fertility assessment and safety, fertility preservation methods, fertility preservation surgery and anti-tumor treatment, fertility timing, pregnancy management and follow-up, and special treatment for pregnancy with cervical cancer.Conclusions:The evidence on fertility management for cervical cancer patients of childbearing age provides a basis for clinical medical and nursing staff to provide fertility guidance for cervical cancer patients. In clinical application, factors such as patient willingness and condition should be fully considered, and personalized treatment plans should be provided to maximize patient benefits.

Objective To investigate the expression of E-cadherin(E-cad),N-cadherin(N-cad),β-catenin (β-cat),which are the markers of Epithelial-mesenchymal transition and analyze their relationships with the clinicopathological features and the prognosis of the laryngeal squamous cell carcinoma.Methods The expression levels of E-cad,N-cad,β-cat in 76 tumor tissues and their corresponding adjacent normal laryngeal tissues were determined by immunohistochemistry method.Relationships between the proteins' expression and clinicopathological features were analyzed.Survival curves were calculated using the Kaplan-Meier method.Differences in the survival rates were analyzed by the log-rank test among different expression groups.Cox's regression model was used to examine the independent predictor of the prognosis of the laryngeal cancer.Results The expression levels of E-cad,N-cad,β-cat in tumor tissues and adjacent normal tissues were statistically significant (P ＜ 0.001).The expression level of E-cad and β-cat in the laryngeal carcinoma was related to lymph node metastasis,clinical pathological stage and differentiation degree (P ＜ 0.05),while N-cad expression level was associated with clinical stage and differentiation degree (P＜0.05).The expression of E-cad was correlated with the expression of β-cat (P =0.001),and the expression of N-cad was correlated with β-cat (P =0.02),but the expression of E-cad was not correlated with N-cad.There were four subgroups of patterns of E-cad and N-cad expression:E-cad (+)/N-cad (-),E-cad (+) /N-cad (+),E-cad (-) /N-cad (-),E-cad (-) /N-cad (+).The expression level of each group was related to the clinical pathological stage and differentiation degree (P ＜ 0.05).The expression level of E-cad/β-cat was associated with lymph node metastasis,clinical pathological stage and differentiation degree (P ＜ 0.01).Log-rank analysis showed that the prognosis of negative and positive groups was statistically different (P ＜ 0.05),and the combined analysis showed that the prognosis of E-cad/N-cad or E-cad/β-cat group was significantly different (P ＜ 0.01).Cox's regression model analysis showed that the clinical stage and β-cat were independent predictors of the prognosis of laryngeal carcinoma.Conclusions The low expression of E-cad,high abnormal expression of N-cad and β-cat played an important role in the occurrence and development of laryngeal carcinoma.It can provide a reference for evaluating clinical prognosis.The clinical pathological stage and β-cat can be used as independent predictors for the prognosis of laryngeal carcinoma.

Objective:To investigate the Chinese anesthesiologist′s proficiency, training experience and needs of flexible bronchoscope-guided awake flexible bronchoscopy intubation (AFBI) using a questionnaire method.Methods:The cluster sampling was used, and self-designed questionnaires that addressed 54 questions in 5 categories were distributed through WeChat and online platforms. The survey took one month, and the answers were automatically recorded by the WeChat server.Results:A total of 1 250 anesthesiologists participated in the survey in 30 provinces of China, 9 of them were not anesthesiologists, and 1 241 (99.28%) questionnaires were validated. In the valid questionnaires, 52.70% (654) of the anesthesiologists were from tertiary hospitals, and 74.78% (928) of the anesthesiologists were attending physicians or above, only 7.57% (94) of the anesthesiologists had sufficient confidence in AFBI. Twenty-five point two two percent (313) of the anesthesiologists preferred fiberoptic intubation as the first tool when dealing with the anticipated difficult airway. Forty-eight point one one percent (597) of the anesthesiologists had implemented AFBI. Among them, 80.74% (482) had experienced unsuccessful AFBI practices. Eight hundred and ninety-four anesthesiologists had received AFBI training, and the most common AFBI training strategy was theoretical lectures. In addition, the degree of satisfaction regarding the theoretical lectures quality, technical training, clinical practice relativity and non-technical skills training was 21.47% (192), 14.32% (128), 12.3% (110) and 17.90% (160), respectively. The degree of satisfaction with all the 4 training elements mentioned above was 7.27% (65).Conclusions:The awareness and practice of Chinese anesthesiologists in terms of clinical application of AFBI to treat difficult airways need to be strengthened at present, and the lack of high-quality AFBI training may be the key.

Objective To analyse the prognosis and risk factors of lung cancer with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) in Tongchuan City, and to provide a theoretical basis for improving the prognosis of patients with lung cancer complicated with AECOPD. Methods A total of 280 patients with lung cancer combined with AECOPD admitted to Tongchuan People's Hospital from January 2021 to August 2022 were selected and divided into survival group and death group according to whether the patients survived during hospitalization. Serum carcinoembryonic antigen (CEA), cytokeratin 19 fragment (CYFRA 21-1) and other tumor markers were compared between the two groups. Lung function was measured by lung function instruments, and the levels of forced expiratory volume in one second (FEV1), forced vital capacity (FVC), FEV1/FVC and other lung function indicators were compared between the two groups. The patients' clinical data were collected from the medical record system, and univariate analysis and logistic regression were used to analyze the independent risk factors affecting the prognosis of patients with lung cancer complicated with AECOP. Results The values of FEV1, FVC and FEV1/FVC in the death group were significantly lower than those in the survival group (P<0.05). Serum CEA and CYFRA 21-1 levels in the death group were significantly higher than those in the survival group (P<0.05). Multiple logistic regression analysis showed that albumin level <35 g/L (OR=2.728), TNM stage III to IV (OR=2.416), multidrug-resistant bacterial infection (OR=2.982), and GOLD grade III to IV (OR=3.417) were independent risk factors for death in patients with lung cancer complicated with AECOPD in Tongchuan City (P<0.05). Conclusion Patients with lung cancer complicated with AECOPD in Tongchuan City have a high risk of death during hospitalization, especially patients with TNM stage III to IV and GOLD grade III to IV. Multi-drug resistant bacteria infection should be actively controlled to improve the albumin level of patients, which is conducive to the prognosis of patients.

【Objective】 To analyze the hepatitis B virus (HBV) infection data of blood donors from 18 domestic blood stations, so as to investigate the HBV infection situation of blood donors. 【Methods】 The positive rate of HBV and its distribution characteristics of regions, the percentage of HBsAg+ ELISA in first-time vs repeated blood donors, and the percentage of HBsAg-/HBV DNA+ blood donors of 18 domestic blood stations during 2017 to 2020 were collected from the Working Platform for Practice Comparison of Blood Centers, and the HBV infection among blood donors were statistically analyzed. 【Results】 From 2017 to 2020, the positive rate of HBV in blood donors among 18 domestic blood stations was 13.48/10 000-144.02/10 000, with the average HBV positive rate in eastern, central and western region at 26.14/10 000, 51.98/10 000 and 41.00/10 000, respectively. The HBsAg+ rate by ELISA among first-time and repeated blood donors was 14.55/10 000-305.39/10 000 vs 1.04/10 000-87.43/10 000 The HBsAg-/HBV DNA+ yield was 1.80/10 000-35.31/10 000. 【Conclusion】 The distribution of HBV infection in blood donors has regional characteristics, and HBV prevalence was low in repeated blood donors. HBsAg ELISA combined with HBV DNA detection can better ensure blood safety.

Amyotrophic lateral sclerosis (ALS) is the most common motor neuron disease. At present, no definite ALS biomarkers are available. In this study, exosomes from the plasma of patients with ALS and healthy controls were extracted, and differentially expressed exosomal proteins were compared. Among them, the expression of exosomal coronin-1a (CORO1A) was 5.3-fold higher than that in the controls. CORO1A increased with disease progression at a certain proportion in the plasma of patients with ALS and in the spinal cord of ALS mice. CORO1A was also overexpressed in NSC-34 motor neuron-like cells, and apoptosis, oxidative stress, and autophagic protein expression were evaluated. CORO1A overexpression resulted in increased apoptosis and oxidative stress, overactivated autophagy, and hindered the formation of autolysosomes. Moreover, CORO1A activated Ca²⁺-dependent phosphatase calcineurin, thereby blocking the fusion of autophagosomes and lysosomes. The inhibition of calcineurin activation by cyclosporin A reversed the damaged autolysosomes. In conclusion, the role of CORO1A in ALS pathogenesis was discovered, potentially affecting the disease onset and progression by blocking autophagic flux. Therefore, CORO1A might be a potential biomarker and therapeutic target for ALS.
