Objective To establish an evaluation index system for the quality and safety of day surgery, and provide standard and professional quantitative bases for monitoring and management of day surgery quality. Methods From December 2021 to May 2022, based on the frame work of the three-dimensional “structure-process-outcome” quality model, two rounds of Delphi method interviews were conducted with 15 day surgery-related management experts, and analytic hierarchy process was used to calculate the weight of each index. Results The effective questionnaire recovery rates of the two rounds of surveys were both 100%; the expert authority coefficients were 0.94 and 0.98, respectively; the variation coefficients were 0.00-0.30 and 0.00-0.24, respectively; the Kendall coordination coefficients were 0.382 (P<0.05) and 0.266 (P<0.05), respectively; and the consistency ratios of all levels were less than 0.1. The final day surgery quality and safety evaluation index system included 3 first-level indicators, 10 second-level indicators, and 43 third-level indicators. Conclusions The quality and safety evaluation index system of day surgery is scientific, reasonable and comprehensive. It can provide a reference for the quality and safety evaluation of day surgery and solidly promote the high-quality development of public hospitals.
Objective To evaluate the security and outcomes of thoracolaparoscopic esophagectomy (TLE) versus open approach (OA) for thoracic esophageal squamous cell carcinoma. Methods From June 2014 to June 2015, 125 patients with thoracic esophageal squamous cell carcinoma underwent esophagectomy through McKeown approach, including TLE (a TLE group, 107 patients, 77 males and 30 females) and OA (an OA group, 18 patients, 13 males and 5 females). The data of operation and postoperative complications of the two groups were analyzed retrospectively. Results There was no statistical difference in the duration of operation and ICU stay and resected lymph nodes around laryngeal recurrent nerve between the TLE group and the OA group (333.58±72.84 min vs. 369.17±91.24 min, P=0.067; 2.84±1.44 d vs. 6.44±13.46 d, P=0.272; 4.71±3.87 vs. 3.89±3.97, P=0.408) . There was a statistical difference in blood loss, total resected lymph nodes and resected lymph nodes groups between TLE group and OA group (222.62±139.77 ml vs. 427.78±276.65, P=0.006; 19.62±9.61 vs. 14.61±8.07, P=0.038; 3.70±0.99 vs. 3.11±1.13, P=0.024). The rate of postoperative complications was 32.7% in the TLE group and 38.9% in the OA group (P=0.608). There was a statistical difference (P=0.011) in incidence of pulmonary infection (2.8% in the TLE group and 16.7% in the OA group). Incidences of complications, such as anastomotic leakage, cardiac complications, left-side hydrothorax, right-side pneumothorax, voice hoarse and incision infection, showed no statistical difference between two groups. Conclusion For patients with thoracic esophageal squamous cell carcinoma, TLE possesses advantages of more harvested lymph nodes, less blood loss and less pulmonary infection comparing with open approach, and is complied with the principles of security and oncological radicality of surgery.
ObjectiveTo analyze the current development of researches on biomarkers for predicting the efficacy of immunotherapy in non-small cell lung cancer and to provide reference for subsequent studies. MethodsStudies on biomarkers for predicting the efficacy of immunotherapy for non-small cell lung cancer indexed in the Web of Science Core Collection from 2017 to 2021 were searched by computer. The annual distribution, journals, authors, countries, institutions, and keywords of studies were visualized and analyzed by CiteSpace. ResultsA total of 426 studies were collected, including 298 articles and 128 reviews. The average number of published studies was about 85, and increased year by year. PD-L1 expression, tumor mutational burden, tumor microenvironment and liquid biopsy were hot keywords in this field. ConclusionIn the future, combination of biomarkers in the liquid biopsy and tumor microenvironment with radiomics analysis will be the research hotspot and frontier in this field for more accurate assessment with tumor-related signatures such as lymphocytic immune status and characteristics of tumor lesions in non-small cell lung cancer patients.
In cases where a tracheal injury exceeds half the length of the adult trachea or one-third of the length of the child trachea, it becomes difficult to perform end-to-end anastomosis after tracheotomy due to excessive tension at the anastomosis site. In such cases, tracheal replacement therapy is required. Advances in tissue engineering technology have led to the development of tissue engineering tracheal substitutes, which have promising applications. Hydrogels, which are highly hydrated and possess a good three-dimensional network structure, biocompatibility, low immunogenicity, biodegradability, and modifiability, have had wide applications in the field of tissue engineering. This article provides a review of the characteristics, advantages, disadvantages, and effects of various hydrogels commonly used in tissue engineering trachea in recent years. Additionally, the article discusses and offers prospects for the future application of hydrogels in the field of tissue engineering trachea.
Objective To analyze the current research application status and hotspots of nanoparticles in the treatment of non-small cell lung cancer (NSCLC) and predict the future development trend. MethodsThe Web of Science database was searched for literatures on nanoparticles use in the treatment of NSCLC from inception to November 2022. CiteSpace, VOSviewer and literature measurement analysis online platform (https://bibliometric.com/) were used for the visual analysis of the number of documents, source journals, authors, organizations, countries and keywords. ResultsA total of 742 English literatures were included. The results showed that the number of published literatures increased year by year from 2011 and reached the peak in 2020. Researches on nanoparticles and NSCLC treatment were mainly concentrated in China, the United States, India and Japan. China is a major research country in this field, but it lacked cooperation with other countries and related institutions. Among numerous research institutions, the Chinese Academy of Sciences was the authoritative and backbone force in this research field, with the number of published literatures ranking first and the research achievements outstanding. The keyword analysis found that "poly lactic-co-glycolic acid nanoparticles (PLGA NPs)" and "photothermal therapy" had become the latest breakout words since 2018. Moreover, the occurrence frequency of related keywords such as "drug delivery" increased significantly, indicating that the application of PLGA NPs in photothermal therapy might be the current research hotspot and future development trend of NSCLC treatment. ConclusionCurrently, the domestic research on the treatment of nanoparticles and NSCLC is in a leading position in the world. The organic combination of nanoparticles with different materials and other NSCLC therapies is expected to improve the prognosis of NSCLC patients. In the future, attempts to develop nanoparticles with different sources and structures and combined with photothermal therapy for the treatment of NSCLC may become a research hotspot of nanoparticles in the treatment of NSCLC.
