OBJECTIVE To investigate the clinical effect of Budigafol combined with Staphylococcus and neisseria tablets in maintenance treatment of patients with stable moderate to severe chronic obstructive pulmonary disease （COPD）. METHODS A total of 122 patients with stable moderate to severe COPD who were admitted to the infections diseases ward of the department of respiratory and critical care medicine in our hospital from October 1， 2021 to January 31， 2023 were divided into control group （n＝61） and observation group （n＝61） according to the random number table method. Patients in the control group were treated with Budigafol inhalation aerosol alone （2 presses each time， twice a day）， and patients in the observation group were treated with Staphylococcus and neisseria tablets （1.2 mg each time， 3 times a day） on the basis of the control group. The treatment course of both groups was 3 months. The quality of life， exercise tolerance， lung function， inflammatory indexes， immune function， as well as the number of acute attacks of COPD and the occurrence of adverse reactions were compared between the two groups before and after treatment. RESULTS Control group and observation group shed 12 and 9 patients， respectively. After treatment， the 6 minute walking distance of the two groups of patients was significantly prolonged compared with that before treatment （P＜0.05）. The COPD assessment test questionnaire score， St George’s respiratory questionnaire score， the ratio of residual volume to total lung capacity， the fractional exhaled nitric oxide， the serum levels of C-reactive protein and interleukin-6 were significantly E-mail：13956685295@163.com decreased compared with those before treatment （P＜0.05）. The forced expiratory volume in one second （FEV1）， the ratio E-mail：13966580920@163.com of FEV1 to forced vital capacity， the percentage of the measured value of carbon monoxide diffusion capacity to the predicted value， and the percentage of the measured value of FEV1 to the predicted value were significantly increased compared with those before treatment （P＜0.05）. The improvement of the above indicators in the observation group was significantly better than that in the control group （P＜0.05）. Compared with before treatment， there was no statistical significance in the immune function indexes of the control group or the serum levels of immunoglobulin A （IgA） and IgM in the observation group after treatment （P＞0.05）. The percentages of CD3+ ， CD4+ ， B lymphocytes and natural killer cells， the levels of CD4+/CD8+ and IgG were significantly increased in the observation group （P＜ 0.05）， the percentage of CD8+ cells was significantly decreased （P＜0.05）， and the improvement degree of the observation group was significantly better than that of the control group （P＜0.05）. There was no significant difference in the number of acute exacerbations of COPD during the follow-up period and the incidence of adverse events during treatment between the two groups （P＞0.05）. CONCLUSIONS Budigafol combined with Staphylococcus and neisseria tablets can effectively improve the immune function of patients with stable moderate to severe COPD， further reduce the level of inflammation， and improve their exercise tolerance and their quality of life with good safety.

ObjectiveTo simulate the microstructure and mechanical properties of tendon tissue and promote its regeneration and repair, electrospinning technology was used to prepare L-polylactic acid (PLLA) fiber membranes loaded with different nano zinc oxide contents and with oriented structures. Physical and chemical characterization and biological performance evaluation were carried out to explore their effects on tendon cell proliferation and differentiation. MethodsPreparation of PLLA fiber scaffolds and PLLA/ZnO fiber scaffolds containing different mass fractions of nano ZnO was performed using electrospinning technology. The physicochemical properties of the scaffold were characterized by scanning electron microscopy, mechanical stretching, and EDS spectroscopy. The scaffold was co-cultured with mouse tendon cells to detect its biocompatibility and regulatory effects on cell differentiation behavior. ResultsThe fiber scaffolds were arranged in an oriented manner, and zinc elements were uniformly distributed in the fibers. The tensile strength and Young’s modulus of PLLA/0.1%ZnO fiber scaffolds were significantly higher than PLLA fiber scaffolds. The number of cells on the surface of PLLA/0.1%ZnO fiber scaffold was significantly higher than that of the PLLA group, and the activity was better; mouse tendon cells exhibit directional adhesion and growth along the fiber arrangement direction. ConclusionThe oriented PLLA/0.1%ZnO fiber scaffold had excellent physicochemical properties, which can significantly promote the oriented growth, proliferation and differentiation of tendon cells. It is expected to be used for tendon tissue regeneration and repair in the future.

Objective:To analyze the multimodal ultrasound characteristics of primary breast cancer and sentinel lymph node (SLN) and to establish a nomogram model for predicting SLN metastasis in invasive breast cancer, thereby providing reference for precise clinical diagnosis and treatment.Methods:A total of 329 patients diagnosed with invasive breast cancer and admitted to the Affiliated Hospital of Nanjing University of Chinese Medicine from June 2018 to October 2023 were retrospectively enrolled. They were randomly divided into a training cohort ( n=230) and a validation cohort ( n=99) in a ratio of 7 to 3. In the training cohort, ultrasound findings and clinical parameters were analyzed, univariate and multivariate Logistic regression analyses were used to identify independent predictive factors for SLN metastasis, and a nomogram model was constructed based on these factors. The ROC curve, calibration curve, and decision curve analysis (DCA) were plotted between the training and validation cohorts to assess the discrimination, calibration, and clinical applicability of the nomogram model. Results:Regression analysis identified 3 independent risk factors for establishing the nomogram prediction model: ratio of the long diameter to the short diameter of SLN ( P=0.020), lymphatic contrast-enhanced ultrasound (LCEUS) enhancement pattern ( P<0.001) and intravenous contrast-enhanced ultrasound (ICEUS) enhancement mode ( P=0.002). The area under the curve (AUC) of the training cohort was 0.888, the accuracy was 0.865; the AUC of the validation cohort was 0.870, the accuracy was 0.859, demonstrating good predictive performance of the model in both cohorts. The calibration curve demonstrated that the nomogram has a strong concordance between predicted and actual probability. DCA demonstrated that the nomogram could increase net benefit within a certain probability threshold range. Conclusions:The nomogram based on ratio of the long diameter to the short diameter of SLN, LCEUS enhancement pattern and ICEUS enhancement mode can effectively predict SLN status in patients with invasive breast cancer, facilitating precise diagnosis and treatment.

Objective: To describe the prevalence of alcohol consumption and the burden of hemorrhagic stroke and hypertensive heart disease attributed to alcohol consumption in adults aged ≥20 years in 31 provinces in China from 2005 to 2018. Methods: Data from several national representative surveys was used to estimate provincial alcohol exposure level of adults aged ≥20 years from 2005 to 2018 by using kriging interpolation and locally weighted regression methods. Global disease burden research method and data, and China's death cause surveillance data were used to calculate the population attributable fraction (PAF) of hemorrhagic stroke and hypertensive heart disease and the deaths due to alcohol consumption in men and women aged ≥20 years in 31 provinces in China. China census data of 2010 were used to calculate the attributable standardized mortality rate. Results: In 2005 and 2018, the prevalence of alcohol consumption was 58.7% (95%CI: 57.8%-59.5%) and 58.4% (95%CI: 57.6%-59.3%), respectively, in men and 17.0% (95%CI: 16.6%-17.4%) and 18.7% (95%CI:18.1%-19.3%), respectively, in women. The daily alcohol intake was 24.6 (95%CI: 23.8-25.3) g and 27.7 (95%CI: 26.8-28.7) g, respectively, in men and 6.3 (95%CI: 6.0-6.5) g and 5.3 (95%CI: 5.0-5.6) g, respectively, in women. Alcohol exposure level was higher in the provinces in central and eastern China than in western provinces. The lowest exposure level was found in northwestern provinces. From 2005 to 2018, the PAF of hemorrhagic stroke death due to alcohol consumption increased from 5.5% to 6.8%, the attributable deaths increased from 50 200 to 59 100, while the PAF of hypertensive heart disease death due to alcohol consumption increased from 7.0% to 7.7%, the attributable deaths increased from 15 200 to 29 300. The PAF of hypertensive heart disease and hemorrhagic stroke was higher in men than in women, and in central and eastern provinces than in western provinces. In 2018, the standardized mortality rates of hemorrhagic stroke and hypertensive heart disease attributed to alcohol consumption were 4.58/100 000 and 2.11/100 000, respectively. Conclusions: The prevalence of alcohol consumption in men and daily alcohol intake of drinkers were relatively high in China, especially in eastern provinces. Alcohol exposure level was lower in women than in men. Regional measures should be taken to reduce the alcohol intakes in men and current drinkers in order to reduce the health problems caused by alcohol consumption.

We wished to establish an expert consensus on late stage of critical care (CC) management. The panel comprised 13 experts in CC medicine. Each statement was assessed based on the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) principle. Then, the Delphi method was adopted by 17 experts to reassess the following 28 statements. (1) ESCAPE has evolved from a strategy of delirium management to a strategy of late stage of CC management. (2) The new version of ESCAPE is a strategy for optimizing treatment and comprehensive care of critically ill patients (CIPs) after the rescue period, including early mobilization, early rehabilitation, nutritional support, sleep management, mental assessment, cognitive-function training, emotional support, and optimizing sedation and analgesia. (3) Disease assessment to determine the starting point of early mobilization, early rehabilitation, and early enteral nutrition. (4) Early mobilization has synergistic effects upon the recovery of organ function. (5) Early functional exercise and rehabilitation are important means to promote CIP recovery, and gives them a sense of future prospects. (6) Timely start of enteral nutrition is conducive to early mobilization and early rehabilitation. (7) The spontaneous breathing test should be started as soon as possible, and a weaning plan should be selected step-by-step. (8) The waking process of CIPs should be realized in a planned and purposeful way. (9) Establishment of a sleep-wake rhythm is the key to sleep management in post-CC management. (10) The spontaneous awakening trial, spontaneous breathing trial, and sleep management should be carried out together. (11) The depth of sedation should be adjusted dynamically in the late stage of CC period. (12) Standardized sedation assessment is the premise of rational sedation. (13) Appropriate sedative drugs should be selected according to the objectives of sedation and drug characteristics. (14) A goal-directed minimization strategy for sedation should be implemented. (15) The principle of analgesia must be mastered first. (16) Subjective assessment is preferred for analgesia assessment. (17) Opioid-based analgesic strategies should be selected step-by-step according to the characteristics of different drugs. (18) There must be rational use of non-opioid analgesics and non-drug-based analgesic measures. (19) Pay attention to evaluation of the psychological status of CIPs. (20) Cognitive function in CIPs cannot be ignored. (21) Delirium management should be based on non-drug-based measures and rational use of drugs. (22) Reset treatment can be considered for severe delirium. (23) Psychological assessment should be conducted as early as possible to screen-out high-risk groups with post-traumatic stress disorder. (24) Emotional support, flexible visiting, and environment management are important components of humanistic management in the intensive care unit (ICU). (25) Emotional support from medical teams and families should be promoted through"ICU diaries"and other forms. (26) Environmental management should be carried out by enriching environmental content, limiting environmental interference, and optimizing the environmental atmosphere. (27) Reasonable promotion of flexible visitation should be done on the basis of prevention of nosocomial infection. (28) ESCAPE is an excellent project for late stage of CC management.

Methods Using electromagnetic navigation to measure the anatomical structure of the central and paracentral ventral skull base on 10 fresh cadavers, the internal carotid artery (ICA) was the most important. Results Electromagnetic navigation helped to determine the course of important neurovascular. The ICA of the ventral skull base was divided into 5 segments+ 7 major branches, and the length and course of each were measured and recorded. Conclusion The identification and protection of ICA is the key to EEA treatment of ventral skull base lesions, and electromagnetic navigation assistance can improve the efficiency and safety of EEA surgery.

Influenza is an infectious respiratory disease caused by the influenza viruses. Older people, infants and people with underlying medical conditions could have a higher risk of severe influenza symptoms and complications. The co-infection of Coronavirus Diseases 2019 (COVID-19) with influenza viruses could lead to the complication of prevention, diagnosis, control, treatment, and recovery of COVID-19. Influenza vaccine and COVID-19 vaccine overlapped in target populations, vaccination time, and inoculation units. Although there was insufficient evidence on the immunogenicity and safety of co-administration of influenza vaccine and COVID-19 vaccine, World Health Organization and some countries recommended co-administration of inactivated influenza vaccine and COVID-19 vaccine. This review summarized domestic and international vaccination policies and research progress, and put forward corresponding suggestions in order to provide scientific support for the formulation of vaccination strategy on seasonal influenza vaccine and COVID-19 vaccine.

Objective:To explore the alteration of JAK2/STAT3 pathway after carbon ion ( 12C 6+) irradiation and the difference in the infiltration of CD8 + T cells in lung cancer regulated by downstream protein FOXP3. Methods:Significantly altered JAK2/STAT3 pathway and related differentially-expressed genes and proteins such as FOXP3 in lung cancer after carbon ion irradiation were screened based on RNA sequencing analysis in the Lewis tumor model of C57BL/6 mice. The correlation between FOXP3 and major immune cell infiltration in the immune microenvironment of lung cancer was analyzed using the ssGSEA immune infiltration algorithm in the R software "GSVA" and CD8 + T cell infiltration in the immune microenvironment of lung cancer was evaluated based on the carbon ion combined with STAT3 inhibition pathway (niclosamide). Results:The JAK2/STAT3 pathway was inhibited and the expression of related genes and proteins was downregulated in lung cancer after carbon ion irradiation. Immune scoring based on the ssGSEA algorithm showed that FOXP3 expression was significantly negatively correlated with CD8 + T cell infiltration in the immune microenvironment of lung cancer. The role of targeting the JAK2/STAT3 pathway in increasing CD8 + T cell infiltration in lung cancer was further clarified by carbon ion irradiation combined with STAT3 inhibition (niclosamide). Conclusion:Carbon ion irradiation ( 12C 6+) can play a synergistic role with immunotherapy by targeting the JAK2/STAT3 pathway.
