Objective To analyze the effect of graded exercise rehabilitation in patients with acute exacerbation of chronic obstructive pulmonary disease,and to provide references for clinical nursing practice.Methods A total of 70 patients with acute exacerbation of chronic obstructive pulmonary disease who met the criteria in the Department of Respiratory Medicine of a tertiary hospital in Zunyi City from September to December 2023 were randomly divided into an experimental group and a control group(with 35 cases in each group).The experimental group implemented graded exercise rehabilitation based on the Global Chronic Obstructive Pulmonary Initiative guidelines,and the control group implemented routine exercise rehabilitation.After intervention,the lung function,blood gas analysis,oxygenation index,6 min walking test and the incidence of complications related to non-invasive mechanical ventilation were compared between the 2 groups.Results Finally,34 cases were included in the experimental group and 35 cases in the control group.After intervention,the forced expiratory volume in the first second of the experimental group was improved compared with the control group(P＜0.05).The 6-minute walking test of the experimental group was higher than that of the control group(P＜0.05).The total incidence of non-invasive mechanical ventilation-related complications in the experimental group was lower than that in the control group(P＜0.05).There was no significant difference in blood gas analysis and oxygenation index between the 2 groups(P＜0.05).Conclusion The implementation of graded exercise rehabilitation based on the Global Chronic Obstructive Pulmonary Initiative guidelines can help patients with acute exacerbation of chronic obstructive pulmonary disease improve their respiratory function,improve their exercise endurance,and reduce non-invasive mechanical ventilation-related complications.

Objective To evaluate the efficacy and safety of six kinds of commonly used traditional Chi-nese medicine combined with mesalazine in the treatment of ulcerative colitis(UC)based on frequency statis-tical network meta-analysis.Methods Randomized controlled trials(RCT)of oral Chinese medicine for the treatment of UC were searched from the establishment of the database to June 2024 of PubMed,CNKI,Wan-fang,VIP,Sinomed and other databases.The quality of the included literatures was evaluated by Cochrane bias risk assessment tool,and the data were statistically analyzed by Stata MP17.0 software.Results A total of 24 RCTs involving 1 939 patients were included,involving 6 kinds of traditional Chinese medicine and Chinese pa-tent medicine,including 4 macro and micro outcome indicators.In terms of improving the total clinical effec-tive rate,Shaoyao decoction,Gancao Xiexin decoction,Huangqin decoction granule,Baitouweng decoction,Kangfuxin liquid,Shenlingbaizhu powder+mesalazine were all superior to using mesalazine alone,and Kang-fuxin liquid+mesalazine had the best effect(P<0.05).In terms of down-regulation of interleukin(IL)-6 expression in colonic mucosa,Shaoyao decoction,Gancao Xiexin Decoction,Huangqin Decoction granules,Pul-satilla decoction,Kangfuxin Liquid+mesalazine were better than using mesalazine alone,and Pulsatilla De-coction+mesalazine had the best effect on reducing IL-6(P<0.05).In terms of down-regulation of colonic mucosal tumor necrosis factor(TNF)-α expression,Shaoyao decoction,Gancao Xiexin decoction,Huangqin decoction granule,Baitouweng decoction,Shenlingbaizhu decoction+mesalazine was better than using me-salazine alone,and Gancao Xiexin decoction+mesalazine had the best effect(P<0.05).In terms of down-regulation of IL-10 expression in colonic mucosa,Pulsatilla decoction+mesalazine was better than mesalazine alone(P<0.05).Conclusion Traditional Chinese medicine combined with mesalazine could alleviate the clin-ical symptoms of UC patients,improve inflammatory factor indicators,eliminate inflammation,and show a better treatment effect for UC than mesalazine used alone.

Turning to critical illness is a common stage of various diseases and injuries before death. Patients usually have complex health conditions, while the treatment process involves a wide range of content, along with high requirements for doctor′s professionalism and multi-specialty teamwork, as well as a great demand for time-sensitive treatments. However, this is not matched with critical care professionals and the current state of medical care in China. Telemedicine, which shortens the distance of medical professionals and the gap of disease diagnosis and treatments in various regions through electronic information, can effectively solve the current problem. Therefore, there is an urgent need to develop a standardized, high-quality visualization telemedicine round system .Therefore, experts have been organized to search domestic and foreign literature on telemedicine round for critically ill patients and to form this consensus based on clinical experiences so as to further improve the level of critical care treatments in regions.

Objective:To investigate the concern about pollen broadcasting in Chinese population from multiple dimensions and to understand the information about allergic rhinitis (AR) in China by analyzing related factors.Methods:From March 1 to September 30, 2022, a large-scale multi-center cross-sectional survey was conducted based on the Questionnaire Star platform in 21 Chinese hospitals. A total of 7 056 subjects from 7 regions in China: Northeast, North, East, Central, South, Southwest, and Northwest China were included. Basic characteristics (including social demographic characteristics and disease characteristics of AR patients), concern about pollen broadcasting, the willingness of pollen-induced AR (PiAR) patients to receive pollen broadcasting, and the treatment satisfaction rate of AR patients were collected. The chi-square test, multivariate linear regression model, and Logistic regression analysis were used to analyze the concern about pollen broadcasting in the Chinese population and related factors from multiple dimensions.Results:Among 7 056 subjects, 23.02% were concerned about pollen broadcasting. Among 3 176 self-reported AR and 1 019 PiAR patients, 25.60% and 39.16% were concerned about pollen broadcasting, respectively, which was higher than that of non-AR or non-PiAR subjects ( χ2 value was 21.74 and 175.11, respectively, both P<0.001). Among AR patients, the proportion of spring and autumn allergen-positive patients concerned about pollen broadcasting was higher than that in perennial allergen-positive patients ( χ2 value was 20.90 and 19.51, respectively, both P<0.001). The proportion of AR patients with asthma, sinusitis, allergic conjunctivitis, and cardiovascular and cerebrovascular diseases was higher than those without complications ( χ2 value was 50.83, 21.97, 56.78, 7.62, respectively, all P<0.05). The proportion of AR patients in North China who could find pollen broadcasting locally was 31.01%, significantly higher than those in other regions (all P<0.05). Multivariate linear regression model analysis showed that among PiAR patients, those with higher per capita household income and higher AR disease cognition levels had been concerned about pollen broadcasting in the past, and those complicated with allergic conjunctivitis had stronger intention to receive pollen broadcasting (B value was 0.24, 0.13, 0.66, 0.47, respectively, all P<0.05). The higher the disease cognition level of PiAR patients, the stronger their willingness to actively participate in treatment ( R2=0.72, P<0.001). Only 18.89% of AR patients felt satisfied with the treatment effect. Logistic regression analysis showed that in AR patients, the treatment satisfaction rate was significantly higher among those concerned about pollen broadcasting compared to those who were not ( OR=1.83, P<0.001). Conclusions:Currently, the dissemination of pollen broadcasting in China is hindered by various factors such as disease cognition level. The treatment satisfaction among AR patients remains unsatisfactory.
