Idiopathic pulmonary fibrosis (IPF), as a progressive lung disease, has a poor prognosis and no reliable and effective therapies. IPF is mainly treated by organ transplantation and administration of chemical drugs, which are ineffective and induce side effects, failing to meet the clinical needs. Therefore, developing safer and more effective drugs has become an urgent task, which necessitates clear understanding of the pathogenesis of IPF. The available studies about the pathogenesis of IPF mainly focus on macrophage polarization, epithelial-mesenchymal transition (EMT), oxidative stress, and autophagy, while few studies systematically explain the principles and links of the pathogeneses. According to the traditional Chinese medicine theory, Qi deficiency and blood stasis and Qi-Yang deficiency are the key pathogeneses of IPF. Therefore, the Chinese medicines or compound prescriptions with the effects of replenishing Qi and activating blood, warming Yang and tonifying Qi, and eliminating stasis and resolving phlegm are often used to treat IPF. Modern pharmacological studies have shown that such medicines play a positive role in inhibiting macrophage polarization, restoring redox balance, inhibiting EMT, and regulating cell autophagy. However, few studies report how Chinese medicines regulate the pathways in the treatment of IPF. By reviewing the latest articles in this field, we elaborate on the pathogenesis of IPF and provide a comprehensive overview of the mechanism of the active ingredients or compound prescriptions of Chinese medicines in regulating IPF. Combining the pathogenesis of IPF with the modulating effects of Chinese medicines, we focus on exploring systemic treatment options for IPF, with a view to providing new ideas for the in-depth study of IPF and the research and development of related drugs.

Objective Triple-negative breast cancer(TNBC)poses a significant challenge for treatment efficacy.CD8+T cells,which are pivotal immune cells,can be effectively analyzed for differential gene expression across diverse cell populations owing to rapid advancements in sequencing technology.By leveraging these genes,our objective was to develop a prognostic model that accurately predicts the prognosis of patients with TNBC and their responsiveness to immunotherapy. Methods Sample information and clinical data of TNBC were sourced from The Cancer Genome Atlas and METABRIC databases.In the initial stage,we identified 67 differentially expressed genes associated with immune response in CD8+T cells.Subsequently,we narrowed our focus to three key genes,namely CXCL13,GBP2,and GZMB,which were used to construct a prognostic model.The accuracy of the model was assessed using the validation set data and receiver operating characteristic(ROC)curves.Furthermore,we employed various methods,including Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway,immune infiltration,and correlation analyses with CD274(PD-L1)to explore the model's predictive efficacy in immunotherapeutic responses.Additionally,we investigated the potential underlying biological pathways that contribute to divergent treatment responses. Results We successfully developed a model capable of predicting the prognosis of patients with TNBC.The areas under the curve(AUC)values for the 1-,3-,and 5-year survival predictions were 0.618,0.652,and 0.826,respectively.Employing this risk model,we stratified the samples into high-and low-risk groups.Through KEGG enrichment analysis,we observed that the high-risk group predominantly exhibited enrichment in metabolism-related pathways such as drug and chlorophyll metabolism,whereas the low-risk group demonstrated significant enrichment in cytokine pathways.Furthermore,immune landscape analysis revealed noteworthy variations between(PD-L1)expression and risk scores, Conclusion Our study demonstrates the potential of CXCL13,GBP2,and GZMB as prognostic indicators of clinical outcomes and immunotherapy responses in patients with TNBC.These findings provide valuable insights and novel avenues for developing immunotherapeutic approaches targeting TNBC.

Purpose To investigate the clinicopathological and histological features of non-small cell lung cancer(NSCLC)patients with high expression of PD-L1 and positive driver muta-tion.Methods The clinical data of 141 patients with PD-L1 high expression and driver mutation-positive NSCLC were col-lected.Immunohistochemical methods,ARMS-PCR,and next-generation sequencing(NGS)were used to detect PD-L1 ex-pression and driver gene mutations.The clinicopathological fea-tures were analyzed and the related literatures were reviewed.Results There were 141 cases NSCLC patients with high ex-pression of PD-L1 in tumor cells,of which 57 cases were≥50%,<60%;≥60%,<70%in 18 cases;≥70%,<80%in 35 cases;≥80%in 31 cases.Among 141 cases NSCLC patients with high PD-L1 expression,53 cases(37.6%)had driver gene mutations,including 4 cases BRAF 15 exon mutations,9 cases MET-associated mutations,17 cases EGFR-associated mutations,16 cases KRAS 2 exon mutations,4 cases EML4-ALK fusion mutations,and 3 cases other rare mu-tations.The high expression of PD-L1 and the occurrence of driver gene mutation were related to the gender,smoking history and pathological type of patients(P<0.05).MET-related mu-tations and KRAS 2 exon mutations were more common in males than in females.All BRAF 15 exon mutations were female.The mean percentage of PD-L1 expression was highest in patients with MET mutation,KRAS 2 exon mutation,and 3 cases rare mutations.In 33 cases with BRAF 15 exon mutation,MET am-plification or mutation,EGFR-related mutation,and 3 cases oth-er rare mutations,PD-L1 was highly expressed in solid,glandu-lar,and micropapillary tumor cells.In 20 cases with KRAS 2 exon mutation and EML4-ALK fusion mutation,PD-L1 was highly expressed in solid nested tumor cells.Conclusion In NSCLC,high expression of PD-L1 and positive driver gene mu-tation are negatively correlated with the degree of tumor differen-tiation.In the poorly differentiated surgical specimens of lung adenocarcinoma,solid,micropapillary,or glandular tubular tumor tissues should be selected as far as possible for PD-L1 ex-pression and driver gene mutation detection.

Objective:To explore the risk factors for lower extremity deep vein thrombosis (DVT) in patients with a spinal cord injury (SCI).Methods:The medical records of 276 hospitalized SCI patients were analyzed retrospectively. They were divided into a DVT group ( n=63) and a no-DVT group ( n=213). Gender, age, blood type, smoking history, surgical history, the time from SCI to admission, cause of SCI, fracture, SCI segments, American Spinal Cord Injury Association grade and complications were compared between the two groups. Binomial logistic regression was used to isolate the risk factors for lower extremity DVT among such patients. Results:Among 84% of the 63 with a lower extremity DVT, it was a calf muscle venous thrombosis. Anemia, hyponatremia and time from SCI to admission (which ranged from 74 to 195 days) were the most serious DVT risk factors.Conclusions:SCI patients are of high risk for DVT, with anemia and hyponatremia being independent risk factors.

Objective:To investigate the value of chromosomes 7 and 8 polysomy in circulating tumor cells (CTCs) for the diagnosis of non-small cell lung cancer, and the correlation of CTCs with clinical pathological characteristics and epidermal growth factor receptor (EGFR) mutations in cancer tissue.Methods:Fifty-seven patients with non-small cell lung cancer and 21 patients with benign lung diseases were enrolled at Beijing Chaoyang Hospital, Capital Medical University, Beijing, China from November 2017 to October 2020. Negative enrichment combined with immunofluorescence in situ hybridization (imFISH) was used to identify CTCs polysomy on chromosomes 7 and 8. EGFR mutations in 56 lung cancer patients was detected using ARMS-PCR.Results:CTCs were detected in 93.0% (53/57) of non-small cell lung cancers and 28.6% (6/21) benign lung lesions. The difference between lung cancer patients and the control cohort was statistically significant ( P<0.01). Receive operator curve (ROC) analyses showed that, when the cut-off value was 1 cell/3.2 mL, Youden index had the highest sensitivity of 93.0% and specificity of 71.4% (AUC=0.906, 95% CI:0.833-0.980, P<0.01). The positive rate of CTCs in stage Ⅲ-Ⅳ cancers was significantly higher than that in stage Ⅰ-Ⅱ ( P=0.023). No significant correlation was observed between positive rate of CTCs or chromosome polysomy and age, gender, smoking status, pathologic types and EGFR mutation status. The number of CTCs in EGFR mutated group was higher than that in the non-mutated group (6.5±1.1 vs. 3.7±0.7, P=0.045). The detection rate for CTCs ≥5 in the EGFR mutated group was also higher than the EGFR non-mutated group (52.0% vs. 19.4%, P=0.010). Conclusion:Detection of CTCs with chromosomes 7 and 8 polysomy has potential value in auxiliary diagnosis of non‐small cell lung cancer, and the number of CTCs is correlated to TNM stage and EGFR gene mutation status.

Total hysterectomy is a treatment for cervical intraepithelial neoplasia Ⅲ (CINⅢ), and its recurrence rate is very small. In recent years, with the development of colposcopy and the increase of postoperative follow-up rate, the detection rate of vaginal intraepithelial neoplasia (VAIN) and vaginal cancer after CINⅢ hysterectomy has increased significantly. In recent years, a number of studies have found that persistent human papillomavirus (HPV) infection is the most important factor leading to the recurrence of vaginal stump after CINⅢ level hysterectomy, so eliminating HPV infection can improve the patient's performance. The prognosis of persistent HPV infection is affected by many factors. The author reviewed the factors related to the clearance of HPV after CINⅢ hysterectomy. The purpose of this study is to provide a theoretical basis for improving the prognosis of patients and delaying the recurrence time after CINⅢ hysterectomy.
