Inflammatory diseases (IDs) are a general term of diseases characterized by chronic inflammation as the primary pathogenetic mechanism, which seriously affect the quality of patient′s life and cause significant social and medical burden. Current drugs for IDs include nonsteroidal anti-inflammatory drugs, corticosteroids, immunomodulators, biologics, and antioxidants, but these drugs may cause gastrointestinal side effects, induce or worsen infections, and cause non-response or intolerance. Given the outstanding performance of metal polyphenol network (MPN) in the fields of drug delivery, biomedical imaging, and catalytic therapy, its application in the diagnosis and treatment of IDs has attracted much attention and significant progress has been made. In this paper, we first provide an overview of the types of IDs and their generating mechanisms, then sort out and summarize the different forms of MPN in recent years, and finally discuss in detail the characteristics of MPN and their latest research progress in the diagnosis and treatment of IDs. This research may provide useful references for scientific research and clinical practice in the related fields.

OBJECTIVE: To analyze the effects of the Focused Solution Model Nursing intervention on quality of life, negative emotions of the patients with prostate cancer. Methods： A total of 82 prostate cancer patients who were diagnosed and treated at the General Hospital of Eastern Theater Command between September 2022 and September 2024 were included and randomly divided into study group and control group by the method of random number table, with 41 patients in each group. The patients in the study group were treated with Focused Solution Model Nursing intervention. And the routine care was used in the control group The quality of life and negative emotions were compared between the two groups by using the scales of World Health Organization Quality of Life-Brief (WHOQOL-BREF), HAMA and HAMD. RESULTS: Compared to the control group, the patients in the study group exhibited significantly higher scores in the physiological, psychological, environmental, and social relationship domains of the WHOQOL-BREF scale (P<0.05). The scores of HAMA and HAMD in study group were lower than those of the control group (P<0.05). Additionally, all subscales of the Social Impact Scale including social exclusion, internalized shame, social isolation and economic discrimination were significantly lower than those of the study group (P<0.05). CONCLUSION Focused Solution Model Nursing intervention can effectively improve the quality of life and negative emotions of the prostate cancer patients in the clinical treatment.

Objective This study aimed to comprehensively analyze and compare the clinicopathological features and prognosis of Chinese patients with human epidermal growth factor receptor 2(HER2)-low early breast cancer(BC)and HER2-IHC0 BC. Methods Patients diagnosed with HER2-negative BC(N=999)at our institution between January 2011 and December 2015 formed our study population.Clinicopathological characteristics,association between estrogen receptor(ER)expression and HER2-low,and evolution of HER2 immunohistochemical(IHC)score were assessed.Kaplan-Meier method and log-rank test were used to compare the long-term survival outcomes(5-year follow-up)between the HER2-IHC0 and HER2-low groups. Results HER2-low BC group tended to demonstrate high expression of ER and more progesterone receptor(PgR)positivity than HER2-IHC0 BC group(P<0.001).The rate of HER2-low status increased with increasing ER expression levels(Mantel-Haenszel χ2 test,P<0.001,Pearson's R=0.159,P<0.001).Survival analysis revealed a significantly longer overall survival(OS)in HER2-low BC group than in HER2-IHC0 group(P=0.007)in the whole cohort and the hormone receptor(HR)-negative group.There were no significant differences between the two groups in terms of disease-free survival(DFS).The discordance rate of HER2 IHC scores between primary and metastatic sites was 36.84%. Conclusion HER2-low BC may not be regarded as a unique BC group in this population-based study due to similar clinicopathological features and prognostic roles.

Objective:To explore the optimization of surgical procedures for laryngotracheal stenosis and its effect analysis.Methods:The data of 32 patients with acquired laryngotracheal stenosis who received surgical treatment from October 2015 to December 2021 were analyzed retrospectively. The age ranged from 19 to 72 years, with an average of (34.0±9.0) years. The medical history ranged from 1 to 32 months (median 3 months). As for etiology, there were 30 cases of iatrogenic laryngotracheal stenosis, including 20 cases of tracheal intubation and 10 cases of tracheotomy (7 cases of percutaneous tracheotomy and 3 cases of traditional tracheotomy). There were 1 case of laryngotracheal trauma and 1 case of airway Penicillium marneffei infection. According to Myer-Cotton grading system, grade Ⅳ stenosis was found in 14 cases, including 12 cases involving trachea and 2 cases involving trachea and subglottic area.There were 18 cases of grade Ⅲ, all of which involved the cervical trachea 5 cases failed in operation in other hospitals. According to stenosis grading, course of disease, primary disease control and the patient′s general condition, the surgical plan was determined individually. The operations of end-to-end anastomosis, circumferential tracheal partial resection, T-tube placement and CO 2 laser tracheal scar resection were performed respectively. The recovery of airway function and perioperative complications were observed one year after operation. Results:End-to-end anastomosis was performed in 16 cases, and partial circumferential tracheal resection in 2 cases, and tracheal granulation (scar) resection by CO 2 laser in 2 cases and T-tube insertion in 12 cases. Eighteen cases which performed end-to-end anastomosis, partial resection of circumferential trachea in and 2 cases which performed laser tracheal scar resection were all recovered airway function at one stage. After 1 year, 19 cases were cured and 1 case was effective. Of 12 patients with T tube implantation, 11 cases were successfully extubated after 6-12 months, 7 cases were cured after 1 year, 2 cases were effective and 3 cases were ineffective. Among the 3 cases of failure, 2 cases were successfully extubated by sleeve resection and end-to-end anastomosis in the second stage, and the other case refused to accept other treatment methods and the T-tube was placed again, and the tube was blocked and the patient survived. During the follow-up period, the total cure rate was 87.5%, the effective rate was 9.4%, and the total extubation rate was 96.9%.The most common complication was subcutaneous emphysema, accounting for 78% (25/32), but no serious mediastinal emphysema or pneumothorax occurred. In the T-tube implantation group, granulation tissue grew in different degrees around the neck wound after operation, and improved or disappeared after 6-9 months. Anterior cervical tracheal fistula occurred in 4 cases of T-tube implantation group after extubation, which were cured by sealing the stoma. There were no complications such as severe bleeding or perioperative death. Conclusion:When there were various factors, the optimization of the surgical plan according to the degree of stenosis, the course of disease, the control of primary disease and the general condition was an important guarantee to improve the curative effect of laryngotracheal stenosis.
