In recent years， the incidence of pulmonary nodules has kept rising. To give full play to the advantages of traditional Chinese medicine （TCM） in the treatment of pulmonary nodules and identify the breakthrough points of integrating TCM with Western medicine， the China Association of Chinese Medicine organized medical experts in TCM and western medicine to carry out in-depth discussion regarding this disease. The discussion encompassed the modern medical advances， TCM theories of etiology and pathogenesis， the role and advantages of TCM in the whole course management of pulmonary nodules， contents and methods of research on pulmonary nodules， and science popularization work， aiming to provide a reference for clinical practice and scientific research. After discussion， the experts concluded that the occurrence of pulmonary nodules was rooted in the deficiency of the lung and spleen and triggered by phlegm dampness， blood stasis， and Qi stagnation. TCM can treat pulmonary nodules by controlling and reducing nodules， improving physical constitution， ameliorating multi-system nodular diseases， reducing anxiety and avoiding excessive diagnosis and treatment， and serving as an alternative for patients who are unwilling or unfit for surgical treatment. At present， the optimal diagnosis and treatment strategy for pulmonary nodules has not been formed， which needs to be further studied from multiple perspectives such as clinical epidemiology， biology， and evidence-based medicine. The primary task of current research is to find out the advantages， effective prescriptions， and target populations and determine the effective outcomes of TCM in the treatment of pulmonary nodules. At the same time， basic research should be carried out to explore the etiology and biological behaviors of pulmonary nodules. The expert consensus on the diagnosis and treatment of pulmonary nodules with integrated TCM and Western medicine needs to be continuously revised to guide clinicians to conduct standardized， scientific， and accurate effective diagnosis and treatment.

ObjectiveTo investigate the effect and mechanism of Yiqi Wenyang Huwei decoction （YWHD） on airway inflammation in bronchial asthma （BA） rats based on transforming growth factor-β₁ （TGF-β₁）/SMAD family member 3 （Smad3） signaling pathway. MethodSixty male SD rats were randomly divided into a normal group， a model group， a dexamethasone （DEX） group， and low-， medium-， and high-dose YWHD groups， with 10 rats in each group. The BA model was induced by intraperitoneal injection of 1 mL of ovalbumin （OVA）-aluminum hydroxide suspension for sensitization， followed by nebulization with 2% OVA. One hour before daily OVA nebulization， the control group was treated with saline， the DEX group with DEX solution at 0.2 g·L^-1， and the low-， medium-， and high-dose YWHD groups with YWHD at 1， 2， 4 g·mL^-1， respectively. General conditions and lung function were observed. Bronchoalveolar lavage fluid （BALF） and serum were collected to count inflammatory cells in BALF and measure immunoglobulin E （IgE） levels in serum and inflammatory cytokines in BALF using enzyme-linked immunosorbent assay （ELISA）. Pathological changes in lung tissues， collagen deposition， and airway mucus secretion were observed by hematoxylin-eosin （HE）， Masson， and periodic acid-Schiff （PAS） staining. TGF-β₁/Smad3-related mRNA and protein levels in lung tissues were determined by Real-time fluorescent quantitative polymerase chain translation （Real-time PCR） and Western blot analysis. ResultCompared with the normal group， the model group showed increased total airway resistance （RL） and decreased dynamic compliance （Cdyn） （P<0.05， P<0.01）， elevated serum IgE levels， increased inflammatory cell counts， and higher inflammatory cytokine levels in BALF （P<0.01）. Additionally， there was significant inflammatory cell infiltration， collagen deposition， and mucus secretion in lung tissues. The levels of TGF-β₁， α-smooth muscle actin （α-SMA）， and Smad3 phosphorylation in lung tissues were significantly increased （P<0.01）. Compared with the model group， the DEX group and high-dose YWHD group exhibited significantly reduced RL （P<0.01）， improved lung dynamic compliance （P<0.05）， and lower serum IgE levels， inflammatory cell counts， and inflammatory cytokine levels in BALF （P<0.05）. Moreover， these treatments alleviated pathological damage in lung tissues and reduced the levels of TGF-β₁， α-SMA， and Smad3 phosphorylation （P<0.01）. ConclusionYWHD reduces airway inflammation， improves pathological damage， and mitigates airway remodeling in bronchial asthma rats， possibly by downregulating TGF-β₁， α-SMA protein levels， and Smad3 phosphorylation.

Objective:To construct a leadership evaluation indicator system for managers in primary healthcare institutions.Methods:This study was a qualitative research. Based on the Chinese Academy of Sciences′ Five Forces Model of Leadership, the framework of the leadership evaluation indicator system for primary healthcare institution managers was initially constructed through literature review, expert interviews, surveys, and group discussions. From November 2020 to June 2021, 19 experts were invited to participate in two rounds of Delphi expert consultations. Based on the consultation results, the leadership evaluation indicator system for primary healthcare institution managers was developed, and the analytic hierarchy process (AHP) was used to determine the weight of each indicator.Results:Nineteen consulting experts were included in the study, 13 of whom were aged 40 years or older, and seven of whom had 20 years or more of professional experience. The response rates of the two rounds of Delphi expert consultation questionnaires were 18/19 and 19/19, respectively; the authority coefficients of the experts were 0.92 and 0.91, respectively. In the second round of consultation, the coordination coefficients of each level of indicators were 0.640, 0.557, and 0.512 ( P<0.05), respectively. The constructed leadership indicator system for managers of primary healthcare institutions included five primary indicators, 16 secondary indicators, and 44 tertiary indicators. The primary indicators, in order of their weight, were "influence"(0.299),"decisiveness"(0.245),"control"(0.156),"inspiration"(0.150), and "foresight"(0.150). Conclusions:This study is a preliminary construction of a leadership evaluation indicator system for managers of primary healthcare institutions, which can be a reference for the training and evaluation of relevant talents.

Objective:To evaluate the reliability and validity of a questionnaire assessing the leadership qualities of primary healthcare institution managers, and to further clarify the current state of leadership development among management teams of community health service centers in Shanghai.Methods:The study was a cross-sectional survey. It was conducted from August to December 2021, and used a stratified sampling method. Using a self-developed questionnaire for primary healthcare institution managers, we surveyed 279 individuals from 10 community health service centers in Shanghai, including management teams, middle-level cadres, general practitioners, and staff from health administrative departments in their respective districts. Leadership qualities were evaluated on five dimensions: inspiration, decisiveness, control, influence, and foresight. Cronbach′s α coefficient and split half coefficient were used to analyze the reliability of the questionnaire, and confirmatory factor analysis was used to assess the structural validity of the scale.Results:The overall Cronbach′s α reliability of the questionnaire for the comprehensive management of community health service centers was 0.96, and the Spearman-Brown split-half coefficient was 0.94. The validity analysis yielded a KMO value of 0.975, the RMSEA for factor analysis was 0.085, and the adaptation indexes all met the model adaptation conditions. Of the 279 participants, 174 were female (62.4%), 257 held a mid-level or higher professional title (92.1%). The overall leadership score of the community health service center management teams was (4.43±0.59), with the dimensions ranked from highest to lowest as follows: inspiration (4.52±0.55), decisiveness (4.46±0.62), control (4.44±0.60), influence (4.42±0.63), and foresight (4.32±0.69). The foresight score was significantly lower than the other four dimensions (all P<0.05). Conclusions:The questionnaire used to assess the leadership qualities of primary healthcare institution managers is reliable and valid. The development of leadership qualities among management teams of community health service centers in Shanghai is unbalanced, with foresight being the weakest dimension.

Five main themes were identified: leadership studies of individual healthcare administrators, leadership development in healthcare, interest and attitudes of healthcare workers towards leadership learning, applications of leadership in healthcare, and the impact of leadership in healthcare on patients and healthcare organizations.Conclusions:At present, research on the construction of the leadership indicator system in the medical field presents is diverse, with differences in theoretical basis and content. The original and empirical research is still insufficient.

ObjectiveTo investigate the prevalence of liver cirrhosis and the changing trend of the disease burden of liver cirrhosis in the Chinese population from 1990 to 2019， and to provide a data reference for formulating the prevention and treatment strategies for liver cirrhosis in China. MethodsThe Global Burden of Disease Study 2019 was used to collect the data on the incidence rate， mortality rate， disability-adjusted life years （DALY）， years of life lost （YLL）， and years lived with disability （YLD） of liver cirrhosis. The Joinpoint regression model was used to analyze the changing trend of disease burden； the age-period-cohort （APC） model was used to evaluate age， period， and cohort effects； R software BAPC package was used to predict future changes in disease burden. ResultsFrom 1990 to 2019 in China， there were increases in the numbers of liver cirrhosis cases and prevalent cases in the general population， as well as in the male and female populations， while there was a reduction in the number of deaths. From 1990 to 2019， the standardized incidence rate， standardized prevalence rate， and standardized mortality rate of liver cirrhosis in the Chinese population showed a downward trend， with a mean annual reduction of 0.62% （95% confidence interval ［CI］： -0.74% to -0.50%， t=9.99， P<0.001）， 0.44% （95%CI： -0.53% to -0.35%， t=13.18， P<0.001）， and 3.02% （95%CI： -3.12% to -2.93%， t=7.58， P<0.001）， respectively. From 1990 to 2019， the standardized DALY， YLL， and YLD rates of liver cirrhosis in the Chinese population also showed a downward trend， with a mean annual reduction of 3.27% （95%CI： -3.37% to -3.18%， t=6.22， P<0.001）， 3.32% （95%CI： -3.42% to -3.22%， t=9.31， P<0.001）， and 1.42% （95%CI： -1.49% to -1.34%， t=4.93， P<0.001）， respectively. From 1990 to 2019， the incidence rate of liver cirrhosis in the Chinese population first increased and then decreased with age， while the mortality rate showed an increasing trend， and the risks of disease onset and death showed a decreasing trend with time and birth cohort. The predictive model showed that the standardized incidence rate， prevalence rate， mortality rate， and DALY rate of liver cirrhosis in China will show a decreasing trend from 2020 to 2030. Alcohol was the most important risk factor for both male and female populations， followed by medication. ConclusionThe disease burden of liver cirrhosis in China shows a decreasing trend from 1990 to 2019， with sex and age differences， especially in the middle-aged male population. Effective measures should be taken for intervention.

Occupational exposure to ionizing radiation represents a critical factor contributing to health risks in workplaces. Previous experimental and clinical studies have demonstrated that ionizing radiation affects human health. Therefore, scientific assessment of health risk caused by ionizing radiation and effective protection against ionizing radiation are of great importance to formulate the preventive interventions against occupational exposure to ionizing radiation. This review summarizes the advances in the research on health effects, health risk assessment methods, and protective interventions of ionizing radiation. We call for research on the health effects of low-dose radiation, individual difference, and optimization of preventive strategies. In addition, improved mechanisms of health monitoring, periodical healthy examinations, and monitoring of radiation doses should be implemented. Moreover, strict compliance to operating procedures and occupational preventive interventions are recommended. These measures aim to minimize the potential harmlessness of occupational exposure to ionizing radiation, thereby safeguarding the health and safety of individuals exposed to ionizing radiation.

OBJECTIVE To explore the independent factors affecting tissue inflammatory cells changes in recurrent nasal polyps.METHODS The clinical data of 31 patients with nasal polyps who underwent endoscopic surgery at the Department of Otolaryngology Head and Neck Surgery,Yantai Yuhuanding Hospital from December 2007 to December 2021 were selected and analyzed by stepwise regression logistic analysis.RESULTS The number of tissue inflammatory cells in recurrent nasal polyps changed compared with that in primary nasal polyps,and the number and percentage of neutrophils in recurrent polyps increased(P<0.05).Logistic analysis revealed that smoking was an independent risk factor for eosinophilia in recurrent nasal polyps,increasing age was an independent factor for lowering neutrophils,and the comorbid allergic rhinitis and the time interval of recurrence were independent factors for lowering and increasing lymphocytes,respectively.CONCLUSION The number of tissue-infiltrating cells is altered in recurrent polyps compared with primary polyps.Smoking is an independent risk factor for eosinophilia in recurrent polyps.

BACKGROUND:Establishing a nomogram prediction model for postoperative pulmonary infection in hip fractures and taking early intervention measures is crucial for improving patients'quality of life and reducing medical costs. OBJECTIVE:To construct a nomogram risk prediction model of postoperative pulmonary infection in elderly patients with hip fracture,and provide theoretical basis for feasible prevention and early intervention. METHODS:Case data of 305 elderly patients with hip fractures who underwent surgical treatment at Wuxi Traditional Chinese Medicine Hospital Affiliated to Nanjing University of Chinese Medicine between January and October 2020(training set)were retrospectively analyzed.Using univariate and multivariate logistic regression analysis and Hosmer-Lemeshow goodness of fit test,receiver operating characteristic curve was utilized to analyze the diagnostic predictive efficacy of independent risk factors and joint models for postoperative pulmonary infections.Tools glmnet,pROC,and rms in R Studio software were applied to construct a nomogram model for predicting the risk of postoperative pulmonary infection in elderly patients with hip fractures,and calibration curves were further drawn to verify the predictive ability of the nomogram model.Receiver operating characteristic curves,calibration curves,and decision curves were analyzed for 133 elderly patients with hip fractures(validation set)receiving surgery at the same hospital from November 2022 to March 2023 to further predict the predictive ability of the nomogram model. RESULTS AND CONCLUSION:(1)The postoperative pulmonary infection rate in elderly patients with hip fractures in this group was 9.18%(28/305).(2)Single factor and multivariate analysis,as well as forest plots,showed that preoperative hospitalization days,leukocyte count,hypersensitive C-reactive protein,and serum sodium levels were independent risk factors(P<0.05).The Hosmer-Lemeshow goodness of fit test showed good fit(χ2=4.57,P=0.803).Receiver operating characteristic curve analysis was conducted on the independent risk factors and their joint models mentioned above,and the differentiation of each independent risk factor and joint model was good,with statistical significance(P<0.05).(3)The graphical calibration method,C-index,and decision curve were used to validate the nomogram prediction model.The predicted calibration curve was located between the standard curve and the acceptable line,and the predicted risk of the nomogram model was consistent with the actual risk.(4)The validation set used receiver operating characteristic curve,graphic calibration method,and decision curve to validate the prediction model.The results showed good consistency with clinical practice,indicating that the model had a good fit.The nomogram risk prediction model constructed for postoperative pulmonary infection in elderly patients with hip fractures has good predictive performance.The use of the nomogram risk prediction model can screen high-risk populations and provide a theoretical basis for early intervention.
