ObjectiveTo analyze the changes in the degree of coordination of China's major epidemic prevention and control efforts before and after the outbreak of the Corona Virus Disease 2019 (COVID-19), so as to explore the impact of epidemic prevention and control measures on coordination dynamics. MethodsA total of 3 864 policy documents related to epidemic prevention and control from January 2000 to December 2020 across 31 provinces (autonomous regions, and municipalities) in China were systematically collected. Contents specific to collaborative and cooperative efforts were extracted, and the extent of interdepartmental coordination were quantified to assess the effectiveness of epidemic prevention and control efforts. Wilcoxon signed-rank test was adopted to statistically analyze the differences between the indicators before and after the epidemic. ResultsThe average overall coordination level for major epidemic prevention and control in 31 provinces (autonomous regions, and municipalities) increased from 43.06% to 97.62%, and the average coordination levels in the eastern, central, and western China soared from 42.29%, 37.50%, and 47.46%, to 98.81%, 96.20%, and 97.46%, respectively, with statistically significant differences (all P<0.05). In terms of department categorization, coordination levels in the professional departments and the key support departments peaked at 100.00%, while other support departments rose to 95.43%, with an increase of 77.15%, 181.85%, and 139.89%, respectively, exhibiting noteworthy statistically significant differences (all P<0.001). ConclusionThe scope of coordination departments of China’s major epidemic prevention and control exists a remarkable surge following the COVID-19 outbreak, notable heightened coordination is particularly observed among the key support departments. Future endeavors should prioritize the roles played by diverse departments in epidemic prevention and control, enhancing both the clarity of departmental responsibilities and the effectiveness of interdepartmental coordination.

ObjectiveTo systematically evaluate the public health governance capacity of 40 cities in Jiangsu, Zhejiang, and Anhui Provinces, providing a scientific evaluation basis for building a "Healthy Yangtze River Delta". MethodsA comprehensive collection of policy documents, public information reports, and research literature related to public health governance capacity in Jiangsu, Zhejiang, and Anhui Provinces was conducted, totaling 6 920 policy documents, 1 720 information reports, and 1 200 literature pieces. Based on the evaluation standards for an appropriate public health system established by the research team, the basic status of public health governance capacity was assessed to identify the strengths and weaknesses of the 40 cities. ResultsIn 2022, the public health governance capacity score for the 40 cities in Jiangsu, Zhejiang, and Anhui Provinces was (562.5±38.0) points. In terms of specific areas, the emergency response field received the highest score of (791.4±49.7) points, while the chronic disease prevention and control field received the lowest score of (368.2±29.6) points. The Jiangsu-Zhejiang-Anhui region has largely achieved the strategic priority of health, gradually improved public health legal regulations, and established a basic organizational framework with a solid foundation for information and data infrastructure. However, challenges still need to be addressed, such as unstable government funding for public health, unclear departmental responsibilities, and barriers to information interoperability. ConclusionThe public health governance capacity of the 40 cities in Jiangsu, Zhejiang, and Anhui Province has been at a moderate level, but disparities have still existed across regions and fields. In the future, while continuing to deepen existing advantages, it is essential to accurately identify the causes of problems, establish a long-term and stable investment mechanism, enhance information connectivity mechanisms, further clarify departmental responsibilities, and promote the achievement of the "Healthy Yangtze River Delta" goal.

Objective To investigate the effects of chronic intermittent hypoxia(CIH)and reoxygenation on insulin resistance(IR)and expressions of miR-27a-3p/PPARγ/IRS1/PI3K/AKT in rat skeletal muscle.Methods GEO database was used for screening the differentially expressed miRNAs in CIH,and their target genes were subjected to GO and KEGG enrichment analysis followed by construction of the miRNA-mRNA-pathway regulatory network using Cytoscape.In the animal experiment,48 male SD rats were randomly divided into normoxia group and CIH group(8 weeks of CIH followed by 4 weeks of normoxic recovery).Blood and skeletal muscle samples were collected at baseline,8 weeks,and 12 weeks to evaluate the changes in fasting blood glucose(FBG)and fasting insulin(FINS)levels and muscular pathology.RT-qPCR and Western blotting were used to detect the changes in the expressions of miR-27a-3p,PPARγ,GLUT4,IRS1,p-IRS1,PI3K,p-AKT and AKT in the muscular tissues.Results No muscular miRNA datasets for CIH were available in GEO database,from which only a kidney-related dataset(GSE202480)was obtained,based on which a total of 165 differentially expressed miRNAs were identified.GO/KEGG analysis suggested that these miRNAs were involved in muscular regulation and insulin signaling.The miRNA-mRNA-pathway network highlighted miR-27a-3p as a crucial regulator in the PPAR and PI3K/AKT pathway.In the animal experiment,the rats subjected to CIH for 8 weeks showed significantly increased FBG,FINS,HOMA-IR,and PPARγ levels,loose muscle fiber arrangement,decreased cross-sectional area of the muscle fibers,and lowered expressions of miR-27a-3p,p-IRS1/IRS1,PI3K,and p-AKT/AKT in the skeletal muscles.Conclusion CIH increases IR,causes skeletal muscle pathology,downregulates miR-27a-3p expression,upregulates PPARγ expression,and inhibits IRS1/PI3K/AKT insulin signaling in the skeletal muscles of rats,and these changes can be reversed by reoxygenation.MiR-27a-3p may participate in CIH-induced IR by modulating the PPAR γ/IRS1/PI3K/AKT signaling pathway.

Coronary artery calcifications (CAC) is an independent risk factor for cardiovascular disease (CVD). It has been revealed that this condition can be automatically quantified through computerize tomographic (CT) scan contained in radiotherapy plan for patients with breast cancer, with which, physicians can identify the patients with increased risk of CVD after radiotherapy prematurely and take intervention measures in advance. In this article, the current literature and research progress on the correlation between CAC and cardiotoxicity in patients with breast cancer after radiotherapy were reviewed, expecting to provide a strategy to reduce the CVD risk in patients with breast cancer after radiotherapy.

Objective To explore the potential categories and influencing factors of the fear of progression in patients with inflammatory bowel diseases(IBD).Methods IBD patients who received inpatient treatment in a tertiary hospital in Nanjing from July 2022 to July 2023 were selected as the study subjects by convenience sampling method.The General Demographic Information Questionnaire,the Chinese version of the Fear of Progression Questionnaire-Short Form(FoP-Q-SF),the Chinese version of Inflammatory Bowel Disease Self-efficacy Scale(IBD-SES),and Social Support Rating Scale(SSRS)were administered to the participants.We applied one-way ANOVA and Logistic regression analysis to identify the factors associated with the potential categories of the fear of progression.Results A total of 303 retumed questionnaires(out of the 310)were valid,resulting an effective response rate of 97.74％.According to the results of latent profile analysis,we classified the respondents into 3 categories by the fear of progression,namely"low risk fear of disease adaptation group"(n=127,41.91％),"medium risk fear of illness distress group"(n=139,45.88％),"high risk fear of dysfunction group"(n=37,12.21％).3 groups showed statistically significant differences in permanent address,self-rated financial pressure,current disease status and self-efficacy(P＜0.05).Conclusion Patients with IBD had obvious differences in characteristics on the fear of progression.Nursing personnel should formulate personalized intervention strategies based on the classification characteristics of the fear of progression of IBD patients.Moreover,nurses should focus on improving patients'self-efficacy and promoting patients to treat medical care,stress and emotion management correctly.

ObjectiveUsing the Delphi method and analytic hierarchy process （AHP） to screen diagnostic items for qi stagnation syndrome and determine their weights， providing a reference for the development of a diagnostic scale of qi stagnation syndrome. MethodsLiterature related to qi stagnation syndrome were screened from databases including CNKI， Wanfang， VIP， SinoMed （from inception to October 31， 2020）. Through systematic review of literature and expert discussions， the information on the four examinations of traditional Chinese medicine were organized and an item pool was constructed. The Delphi method was used to screen the item indicators， while the AHP was employed to determine their weights. Statistical methods such as mean value， full score ratio， rank sum， unimportant percentage， and coefficient of variation were used for item screening， with the weights calculated by AHP serving as the item weights. ResultsA total of 235 articles and books were included for analysis， resulting in an item pool of 16 items. After three rounds of expert consultation， a total of 84 valid questionnaires were collected， with a total expert enthusiasm coefficient of 99% and authority coefficient of 0.86， 0.84， 0.83， respectively， and the coordination coefficients were 0.45， 0.49， and 0.29， respectively. Through the statistics analysis， 8 diagnosis items were screened out， including distension （stuffi-ness） or distending pain or scurrying pain， wiry pulse， depressed emotions， frequent sighing， deep and wiry pulse， irritability， pale red tongue， and thin white coating. The AHP showed that the order of weights of the first-level indicators from high to low was clinical symptoms， pulse manifestation， and tongue manifestation； the order of weights of the second-level indicators from high to low was distension （stuffiness） or distending pain or scurrying pain， wiry pulse， depressed emotions， frequent sighing， deep and wiry pulse， irritability， pale red tongue， and thin white coating. ConclusionBy applying the Delphi method and AHP to analyze and evaluate the diagnostic items for qi stagnation syndrome， key diagnostic items were screened and their weights determined， laying the foundation for the development of a diagnostic scale for qi stagnation syndrome.

Objective To understand the current status of death anxiety in patients with primary liver cancer and analyze its influencing factors,so as to provide basis for developing individualized psychological guidance and intervention measures.Methods A convenient sampling method was used to select 302 patients with primary liver cancer who were hospitalized in a tertiary hospital in Jiangsu Province from March to November 2022.The General Demographic Information Questionnaire,the Templer's Death Anxiety Scale(T-DAS),the State-Trait Anxiety Inventory(STAI),the Rosenberg Self-esteem Scale(SES)and the Self-perceived Burden Scale(SPBS)were used to conduct questionnaire survey during hospitalization.Single factor analysis and multiple linear regression analysis were applied to analyze the factors influencing the death anxiety in patients with primary liver cancer.Results A total of 298 patients with primary liver cancer were included in the study.The effective recovery rate was 98.68％.The total score of the F-DAS was(7.10±3.43)points;56.38％of the patients had high death anxiety.Multiple linear regression analysis results showed that the factors influencing the death anxiety in patients with primary liver cancer included gender,China liver cancer staging,duration of diagnosis,self-esteem,trait anxiety and self-perceived burden.A total of 49.00％of the variation in death anxiety was explained.Conclusion The death anxiety of patients with primary liver cancer is at a high level.It is suggested that medical staff should pay more attention to female patients with China liver cancer staging IV,diagnosis time＞3 months and low self-esteem,high levels of trait-anxiety and self-perceived burden,in order to develop personalized intervention measures,carry out psychological counseling and emotional support to relieve patients'death anxiety.

Objective:To investigate the value of three-dimensional (3D) CT in diagnosing cricoarytenoid dislocation.Methods:From January 2021 to December 2021, 31 patients with unilateral cricoarytenoid dislocation who had been treated by reduction forceps at the Affiliated BenQ Hospital of Nanjing Medical University were collected retrospectively, and their voice recovered or improved significantly after therapy. The preoperative CT images were reconstructed by volume rendering (VR). The dislocated side (left and right), type of dislocation (total dislocation and subluxation), and dislocation direction (anterior, posterior, internal and external dislocation) of cricoarytenoid dislocation were observed. According to arytenoid articular surface of cricoid cartilage exposed completely or not (caused by arytenoid displacement), they were divided into complete dislocation and subluxation. According to the direction of arytenoid displacement and the part of arytenoid articular surface of cricoid cartilage exposed, they were divided into anterior, posterior, internal and external dislocation. According to the shape of the vocal cords on laryngoscope, anterior and posterior dislocation of each case was judged, and then compared with that of CT.Results:On VR images, there were 28 cases of cricoarytenoid subluxation (90.3%, 28/31) and 3 cases of complete dislocation (9.7%, 3/31). Left cricoarytenoid dislocation was 26 cases (83.9%, 26/31) and right cricoarytenoid dislocation was 5 cases (16.1%, 5/31). Posterior dislocation was 28 cases (90.3%, 28/31) and anterior dislocation was 3 cases (9.7%, 3/31). There were 23 cases of internal dislocation (74.2%, 23/31), 2 cases of external dislocation (6.4%, 2/31), and 6 cases without obvious internal and external dislocation (19.4%, 6/31). Three cases of complete dislocation were left posterior internal dislocation.There were 24 cases of left posterior dislocation (77.4%, 24/31), 4 cases of right posterior dislocation (12.9%, 4/31), 2 cases of left anterior dislocation (6.4%, 2/31) and 1 case of right anterior dislocation (3.2%, 1/31). On laryngoscope, there were 19 cases of posterior dislocation (61.3%, 19/31), 9 cases of anterior dislocation (29.0%, 9/31), 3 cases were difficult to assess (9.7%, 3/31) because of aryepiglottic fold covering. Sixteen cases (55.2%, 16/28) were consistent with 3D CT, and 12 cases (42.8%, 12/28) were inconsistent.Conclusion:The 3D CT is a reliable method to evaluate cricoarytenoid dislocation, which can show dislocated side, type and direction of cricoarytenoid dislocation clearly.

Building a strong public health system has become an urgent task in the new era. Based on more than eight years of systematic research， we believe that five aspects need to be prioritized for a strong system. First， we should change the perspective on public health， using the word “gonggong jiankang” to replace “gonggong weisheng” and the word “gonggong jiankang tixi” to replace “gonggong weisheng tixi”， to lead the public health system development. Second， we should develop a suitable public health system and continuously improve the health capacity for governance. Third， we should make it clear that the goal of building a strong system is not far-fetched， and we need to consolidate the existing institutional advantages of China’s public health system： when encountering major problems， we can maintain a unified goal and mobilize the whole society to cooperate effectively to accomplish the goal. However， we need to make up for shortcomings one by one， especially to solve the key problem of lacking a strong coordination mechanism in daily work. Fourth， we should pursue excellence and consolidate the“suitable” mechanism proven in the process of coping with the COVID-19， so that efficient mechanisms to deal with major issues can be used in routine work， and efforts should be made to consolidate the advantages of prevention and control of infectious diseases and emergency response，so as to achieve the balanced development of regions categories and units.Finally， it is necessary to strengthen the coordination of government and research institutions， in the aspects of technological innovation， talent team building and accurate consulting services， and work together to pursue a suitable and strong system to realize the modernization of the health system and capacity for governance.
