Objective To investigate the diagnostic value of serum human β-defensin 2(HBD2)and soluble growth stimulating gene 2(sST2)levels in pediatric refractory Mycoplasma pneumonia.Methods A total of 145 children diagnosed with Mycoplasma pneumonia were recruited,and divided into refractory pneumonia group(n=53)and common pneumonia group(n=92)based on whether they had refractory or common pneumonia.General data were compared between the two groups.Ser-um HBD2 and sST2 levels were measured using enzyme-linked immunosorbent assay(ELISA).Multi-variate logistic regression analysis was used to identify influencing factors for the occurrence of refracto-ry Mycoplasma pneumonia.Receiver operating characteristic(ROC)curve analysis was performed to evaluate the diagnostic value of serum HBD2 and sST2 levels in refractory Mycoplasma pneumonia.Results The proportion of lung consolidation and pleural effusion in refractory pneumonia group was significantly higher,and the fever time was significantly longer than that in common pneumonia group(P＜0.05).Serum HBD2 and sST2 levels in the refractory pneumonia group were signifi-cantly higher than those in the common pneumonia group(P＜0.05).Multivariate Logistic regres-sion analysis indicated that lung consolidation,pleural effusion,high serum HBD2 level and high serum sST2 level were risk factors for pediatric refractory Mycoplasma pneumonia(P＜0.05).The area under the curve and Youden's index for diagnosing pediatric refractory Mycoplasma pneumonia were 0.817 and 0.557 for serum HBD2 level,and 0.841 and 0.607 for serum sST2 level,respec-tively.Combined diagnosis using both markers resulted in an area under the curve of 0.916 and a Youden's index of 0.721.Conclusion The combined detection of serum HBD2 and sST2 levels holds significant diagnostic value for pediatric refractory Mycoplasma pneumonia.

Objective:To investigate the relationship between the neutrophil- to-lymphocyte ratio (NLR), lymphocyte-to-monocyte ratio (LMR), C-reactive protein (CRP), and the efficacy of immunotherapy in patients with advanced non-small cell lung cancer (NSCLC).Methods:The clinical data of 47 patients with NSCLC who received immunotherapy at The First Affiliated Hospital of Anhui University of Science and Technology from December 2021 to May 2023 were retrospectively analyzed. Based on the duration of immunotherapy, patients with a duration of more than 1 year were classified as having a good immune response, while those with a duration of less than 1 year were classified as having a poor immune response. The clinical pathological characteristics of patients with good and poor immune responses were compared. The cutoff values for NLR, LMR, and CRP were calculated using receiver operating characteristic curves, and patients were grouped based on these cutoff values. The predictive probabilities of different combinations were compared. Univariate and multivariate Cox analyses were performed to identify factors affecting patient survival.Results:Significant differences were observed in the distribution of therapy lines (1 st-line vs. 2 nd-line treatment), NLR, LMR, and CRP levels between patients with good immune response and those with poor immune responses (all P < 0.05). The area under the curve (AUC) for NLR was 0.763 [95% CI: (0.608, 0.918)], the AUC for LMR was 0.715 [95% CI: (0.544, 0.875)], and the AUC for CRP was 0.697 [95% CI: (0.540, 0.853)]. To assess the diagnostic value of combined indicators in predicting the efficacy of immunotherapy in NSCLC, different indicators were combined, resulting in the variables NLR + LMR, NLR + CRP, LMR + CRP, and NLR + LMR + CRP. Receiver Operating Characteristic curves were plotted based on the probabilities. The combination of NLR + LMR + CRP showed the best predictive performance, with an AUC of 0.897 [95% CI: (0.806, 0.988)]. Univariate and multivariate Cox analyses indicated that LMR [ HR: 0.428; 95% CI: (0.213, 0.858), P = 0.017] and the distribution of treatment lines [ HR: 1.815; 95% CI: (1.005, 3.642), P = 0.033] were important independent prognostic factors for progression-free survival. Conclusions:NLR, LMR, and CRP are correlated with immunotherapy efficacy in patients with NSCLC and provide predictive value. LMR and treatment line are independent prognostic factors for progression-free survival.

Renal interstitial fibrosis （RIF） is the main pathological feature of chronic kidney disease caused by a variety of factors. "Kidney deficiency and blood stasis in collateral， miniature mass of renal collateral" is the main pathogenesis of RIF. The deficiency of healthy Qi will influence the kidney Qi， resulting in kidney deficiency and unsmooth qi transformation. As a result， phlegm， heat， stasis， toxin and other excess pathogens block the kidney collaterals， forming miniature masses. The masses accumulate in the renal collaterals， finally leading to RIF. Autophagy is a key process that keeps your body's cells in proper balance by taking aged or damaged components in a cell and recycling them. It is involved in the occurrence and development of RIF. The metabolism of excess pathogens such as phlegm， heat， stasis， and toxin in vivo is related to the degradation and reabsorption of autophagy. Autophagy is a way to eliminate phlegm， heat， stasis， toxin and other excess pathogens. Autophagy dysfunction will cause the accumulation of phlegm， heat， blood stasis， toxin and other excess pathogens， further the stasis of the kidney collaterals， miniature mass in kidney， and finally RIF. Kidney deficiency and blood stasis in collateral are the root cause of autophagy dysfunction， and the miniature mass of renal collateral is the manifestation of autophagy dysfunction. Autophagy dysfunction and miniature mass of renal collateral have the same pathological evolution. In this paper， based on the pathogenesis of "kidney deficiency and blood stasis in collateral， miniature mass of renal collateral" of RIF and RIF-autophagy relationship， this paper discusses the "kidney deficiency and blood stasis in collateral-autophagy dysfunction-miniature mass of renal collateral" relationship in RIF and comprehensively interprets the scientific connotation of the pathogenesis of "kidney deficiency and blood stasis in collateral， miniature mass of renal collateral"， which is expected to lay a basis for explaining the role of autophagy in TCM theory and for the treatment of RIF and research on the mechanism.

Objective To analyze the distribution, survival conditions, and medical support of newly diagnosed occupational pneumoconiosis (hereinafter referred to as pneumoconiosis) patients in Zhangdian District, Zibo City. Methods A total of 1 189 newly diagnosed pneumoconiosis patients in Zhangdian District from 1956 to 2019 were selected as the study subjects using retrospective method. Data of their age of onset, years of occupational exposure, category of working industry, type of pneumoconiosis, and status of medical support was collected and analyzed. Results The median and the 25th-75th percentiles ［M (P₂₅, P₇₅)］ of the age of onset were 51.8 (45.5, 56.1) years, and the mortality was 37.0%. The majority of pneumoconiosis cases were silicosis (45.2%) and coal workers' pneumoconiosis (39.8%). The highest prevalence of pneumoconiosis was in the coal mining and washing industry (42.4%), followed by manufacturing (33.4%). Pneumoconiosis patients in stage Ⅰ,Ⅱ, and Ⅲ accounted for 89.1%, 8.7%, and 2.2%, respectively. The M (P₂₅, P₇₅) of the length of work exposed to dust were 24.1 (16.5, 29.9) years.The higher stage of pneumoconiosis the shorter of the length of work exposed to dust among these pneumoconiosis patients(all P<0.05). The overall survival rate, the 5-year survival rate and the 10-year survival rate of these pneumoconiosis patients were 63.0%, 92.3% and 85.9%, respectively. Among the 749 surviving cases, 60.8% were aged 60.0 to <80.0 years. In terms of social security, 100.0% surviving cases enjoyed basic medical insurance, meanwhile, 96.1% and 81.8% patients were covered by major medical insurances and occupational injury insurances, respectively. The M (P₂₅, P₇₅) of age at death were 73.1 (64.0, 77.1) years. The main causes of death were respiratory diseases (59.3%) and malignant tumors (20.4%). Conclusion The prevalent types of pneumoconiosis in Zhangdian District, Zibo City, are coal workers' pneumoconiosis and silicosis. Medical support and assistance are relatively limited. The pneumoconiosis prevention and control focus should be on silicosis and coal workers' pneumoconiosis, particularly in the manufacturing industry.

Renal interstitial fibrosis（RIF）is a common pathway for the progression of chronic kidney disease to renal failure，and its pathogenesis is mainly related to renal inflammatory damage，oxidative stress，apoptosis，and excessive extracellular matrix（ECM） deposition. Transforming growth factor-β₁（TGF-β₁） signaling pathway，mammalian target of rapamycin（mTOR） signaling pathway and other signaling pathways mediate the occurrence and development of RIF. Because of the complicated mechanism of RIF，there have been no specific prevention and treatment measures in clinical practice. Autophagy is a non-damaging response produced by eukaryotic cells. It maintains the balance of tissue homeostasis through degradation and reabsorption. At present， Chinese medicine has achieved desirable clinical effects with its unique advantages of multiple components，multiple effects，and multiple targets in the treatment of chronic kidney disease to delay the process of RIF. Scholars have found that autophagy is consistent with the Yin-Yang theory and the theory of abdominal mass in traditional Chinese medicine （TCM） to a certain extent，and it is involved in many aspects of RIF. The progression of RIF is closely related to autophagy. The targeted therapy of RIF by intervention in autophagy has become the frontier of research. However，little is known about the role of autophagy in RIF and the regulation of autophagy by Chinese medicine in the treatment of RIF. Therefore，it is necessary to further elucidate the relationship between autophagy and RIF in order to clarify the mechanism of autophagy in RIF and the mechanism of Chinese medicine regulating autophagy in targeted therapy of RIF. This article focused on the correlation between autophagy and RIF based on TCM theory，and systematically summarized the role of autophagy in RIF and the intervention of Chinese medicine by combining the effects of autophagy on inflammation damage，oxidative stress，apoptosis，and excessive ECM deposition in RIF， and the regulation mechanism of autophagy in TGF-β₁ and mTOR signaling pathways in RIF. This study was expected to provide a certain reference for the clinical treatment of RIF and the development of new drugs.

Chronic renal failure （CRF）， a common outcome of various chronic kidney diseases， is characterized by retention of metabolites and toxins， water-electrolyte imbalance， acid-base disturbance， and various symptoms in diverse systems. The incidence and progression of this disease are influenced by many factors， particularly the change of intestinal flora. Previous research shows that the intestinal flora interacts with CRF. For CRF patients， the metabolic waste fails to be cleared in time due to the gradual decline of renal function and thus accumulates in vivo. Moreover， CRF changes the composition of intestinal flora， damages intestinal barrier， and accelerates the synthesis of intestinal uremic toxins and the accumulation in blood. As a result， the renal injury is aggravated. The imbalance of intestinal flora can induce acute kidney injury， increase cardiovascular complications， stimulate immune inflammatory responses， and thus aggravate the progression of CRF. Microbiota-targeted therapy for CRF has become the research focus. According to traditional Chinese medicine， kidney disease is related to the intestine and kidney disease should be treated from the intestine. Spleen and kidney are in the closest relationship with the pathogenesis of CRF and the intestinal flora. Chinese medicine， which features multiple targets， multiple effects， and multiple components， acts on the "gut-kidney axis". It is thus superior in the clinical treatment of CRF and the regulation of intestinal flora. To be specific， it intervenes in intestinal flora to delay the process of CRF. In this paper， based on the correlation of traditional Chinese medicine theory with intestinal flora and CRF， this paper reviewed the interaction between intestinal flora and CRF and traditional Chinese medicine intervention in the intestinal flora for the treatment of CRF， which is expected to serve as a reference for the clinical treatment of this disease and the drug development.

Objective:To explore the event impact in patients with traumatic fractures and analyze its influencing factors.Methods:This study was a cross-sectional survey. From June 2020 to June 2021, 190 patients with traumatic fractures admitted to the Department of Orthopedics of Gansu Provincial Hospital were selected by convenience sampling method as the research object. The General Information Questionnaire, Impact of Event Scale-Chinese (IES-C) , Connor-Davidson Resilience Scale (CD-RISC) and General Self-Efficacy Scale (GSES) were used for investigation. Multiple linear regression was used to explore the influencing factors of event impact in patients with traumatic fractures.Results:A total of 190 questionnaires were distributed, and 177 valid questionnaires were recovered, with a valid recovery rate of 93.2%. Among 177 trauma fracture patients, the total score of the IES-C was (28.33±16.92) , including (13.90±8.51) in the dimension of experience reproduction and (14.10±8.52) in the dimension of avoidance response. Multiple linear regression analysis showed that trauma causes, gender, general self-efficacy, psychological resilience were the influencing factors of event impact of patients with traumatic fractures ( P<0.05) . Conclusions:The event impact of patients with traumatic fractures is at a mild level, and the patient 's gender, general self-efficacy, psychological resilience, and the cause of trauma are important factors that affect the event impact of patients. Clinical medical and nursing staff should timely assess the psychological trauma of patients after trauma, and take individualized psychological intervention according to the influencing factors to reduce the psychological trauma of patients.

Completing the building of a moderately prosperous society in all respects involves various aspects, but it is an imperative task to strengthen areas of weakness.China is a developing country with relatively insufficient medical resources.Yet without health for all, there can be no well-off society for all.The incidence of cancer has been among the top three, playing an important role in the work of national health.Among them, the department of oncology of the First Affiliated Hospital of Anhui University of Technology takes care of cancer patients by holding public lectures——famous doctors' lecture hall, establishing family poverty alleviation wards, establishing " cloud medical treatment" ——WeChat group and distributing brochures during tumor publicity week. All the methods are creative, evaluable and sustainable.It will be further improved in the future to provide more help for cancer patients.
