Objective:To describe the prevalence of preserved ratio impaired spirometry (PRISm) in participants from the China Kadoorie Biobank (CKB) and explore the influencing factors.Methods:The CKB project conducted the baseline survey, the first and the second resurvey in 2004-2008, 2008, and 2013-2014, respectively. Based on the lung function tests, the participants were categorized into three groups: regular, PRISm, and airflow obstruction. The prevalence of PRISm was reported by gender, age, and region at the baseline survey. The secular trend in the prevalence of PRISm was described during the three surveys. Finally, we used the multiple logistic regression model to examine the factors related to PRISm in the baseline survey.Results:After standardization for gender, age, and region according to the sixth national census data in 2010, the overall prevalence of PRISm and airflow obstruction among the 434 760 participants at baseline was 24.8% and 6.1%, respectively. The prevalence of PRISm was higher in rural (25.4%) than that in urban areas (24.3%). Of the 10 study regions, Gansu had the highest prevalence of PRISm (56.0%), while Henan had the lowest (15.4%). After standardization for gender, age, and region according to the baseline population, the prevalence of PRISm decreased from 24.9% at baseline to 15.7% in the second resurvey, and the prevalence of airflow obstruction increased from 5.9% to 21.4%. Unmarried status, current smoking, using solid fuels for cooking, low body weight, being overweight, obesity, and central obesity were associated with an increased risk of PRISm. In contrast, higher education attainments, increased household income, and maintaining a specific degree of physical activity were associated with a reduced risk of PRISm.Conclusions:The prevalence of PRISm was high in adults aged 40 years and above in China, and it varied by sociodemographic and lifestyle factors.

Objective:To explore the current status and research trends of cancer-related cognitive impairment (CRCI) worldwide, and to provide a reference for clinical nursing practice.Methods:Literature related to CRCI nursing was retrieved from the Web of Science Core Collection and China National Knowledge Infrastructure, with the search period from database inception to December 31, 2024. CiteSpace software was used to conduct bibliometric analysis of the included studies.Results:A total of 463 English and 43 Chinese articles were included. The overall number of publications showed an upward trend, with some degree of collaboration among institutions and authors. Research hotspots focused on influencing factors of CRCI, construction of risk prediction models, symptom management, and nursing interventions.Conclusions:The volume of CRCI nursing research has increased annually. Foreign countries started earlier in this field, while China is still in the initial stage. There is a need to strengthen international cooperation, multi-institutional collaboration, and interdisciplinary research to improve research quality and provide guidance for CRCI nursing research development in China.

Cancer therapy-related thrombopenia,which is called"medicinal poison purpura"in tradi-tional Chinese medicine,is a common hematologic adverse reaction during oncology treatment that is dif-ficult to treat due to the differences in oncology treatments and the complexity of the pathogenesis,resul-ting in various degrees of thrombocytopenia.Based on the theory that"spleen controlling blood",this pa-per believes that"medicinal poison purpura"is mainly caused by direct damage to the blood and qi by medicinal poison,leading to qi and blood deficiency;it also attacks the spleen and stomach,resulting in the deficiency of spleen qi and no source of qi and blood production.Due to the spleen deficiency,there is no essence to nourish kidney and bone marrow;their function of generating blood decreases,eventually it becomes"medicinal poison purpura".The theory of"regulating balance and flat regulation"is an im-portant academic idea of our team in the treatment of malignant hematological tumors.In this paper,we have systematically elaborated on the etiology,pathogenesis,and therapeutic principles of the treatment of cancer therapy-related thrombopenia with spleen deficiency pattern through the collation of relevant lit-erature.We believe that the prescription formulated according to the method of invigorating spleen and benefiting qi and controlling blood for the treatment of cancer therapy-associated thrombocytopenia with spleen deficiency pattern is in line with the principle of correspondence between prescription and syn-drome,and correspondence between drugs and syndrome in traditional Chinese medicine,which is theo-retically feasible and has a high clinical application value.

BACKGROUND:Minipigs are often used in research fields such as skin injury,vascular trauma and cosmetic medicine because they are highly similar to human beings in terms of skin tissue structure and cardiovascular system.Hydrogel as a wound repair drug possesses a variety of excellent physicochemical properties such as strong water retention and adhesion,which can provide isolation moisturization and drug release for wounds. OBJECTIVE:To summarize and conclude the progress of the application of trauma models for different experimental purposes of hydrogel therapy for minipigs,to reveal the development status of various types of minipig trauma models,to analyze the deficiencies of minipig trauma models at the present stage. METHODS:The relevant articles published in Web of Science database and CNKI database from the establishment of each database to 2023 were checked,using"piglet,miniature pig,minipig,miniature pig;gel,hydrogel;trauma,injury,wound,lesion,incision"as Chinese search terms and"Miniature Swine,Miniature pig,minipig;gel,hydrogel;injury,wound,lesion,incision"as English search terms.A total of 438 Chinese and English documents were retrieved,and 59 documents were included in the study through the inclusion and exclusion criteria. RESULTS AND CONCLUSION:(1)At present,the main models used clinically for trauma repair are large animal species(dogs and pigs),rabbits,and rodents(rats and mice).Because the skin structure of the minipig is more like that of humans,the minipig is the most ideal animal model for trauma repair.(2)In the in-vitro skin injury model,skin defect model is the basic wound model,which can be divided into full skin defect model and medium-thickness skin defect model according to the depth of the wound defect.Burn wound model and infected wound model are multidimensional models with hot metal scald and bacterial culture imposed on the basis of the skin defect model,which have the advantages of high safety coefficient and low operation difficulty.(3)In the in-vivo trauma repair model,mini-pigs are used as esophageal cricothyrotomy model which is more in line with the pathological state of clinical diseases.Mini-pigs are used in the gastric perforation and vascular hemostasis model,which can visually demonstrate the stronger organ adhesion,hemostatic properties and tissue regeneration-promoting effects of the hydrogel.(4)The specific parts of the pig also has the corresponding mode of use:pig ear is usually used to evaluate the hydrogel drug delayed-release effect.Porcine cellular proteins and pig skin collagen are mostly used to prepare composite hydrogels of tissue origin.

Objective:To investigate the facilitators and hindrances of smoking cessation in patients with chronic obstructive pulmonary disease (COPD), and to provide a basis for developing individualized smoking cessation intervention strategies for COPD patients.Methods:Based on the health ecology theory and using a phenomenological approach in qualitative research, purposive sampling was used to select 15 COPD patients with smoking history who were admitted to Tianjin Fourth Central Hospital from March to May 2023 and face-to-face semi-structured interviews were conducted. Colaizzi seven-step analysis was used to analyze the interview content.Results:A total of 15 COPD patients were interviewed, including 13 males and 2 females, aged 61-75 years old. The facilitators of smoking cessation in COPD patients included complications, sequelae of novel coronavirus infection, fear of death, smoking cessation counseling by medical staff, heavy family financial burden, and smoke-free environment. The hindrances of smoking cessation in COPD patients included milder disease symptoms of COPD, higher levels of nicotine dependence, false disease-related perceptions, family supervision and control, and occupational experience.Conclusions:Smoking cessation in COPD patients is influenced by five factors: personal characteristics, behavioral characteristics, interpersonal network, living and working conditions, and policy environment. Medical staff and relevant national institutions should formulate corresponding smoking cessation strategies according to address the facilitators and hindrances of smoking cessation in COPD patients, so as to further reduce the smoking prevalence of COPD patients, promote the health of patients and reduce the burden of disease.
