Objective: Despite the availability of numerous treatment options, managing patients with platinum-resistant ovarian cancer (PROC) remains challenging, and the prognosis of PROC is notably unfavorable. This retrospective study aimed to assess the efficacy and safety of combined anlotinib-oral etoposide treatment for patients with PROC. Methods: Data of 23 patients who were diagnosed with PROC from January 2020 to November 2022 and treated with anlotinib combined with oral etoposide for at least 2 cycles were retrospectively analyzed. Results: Among per-protocol patients, 9 (45.0%; 95% confidence interval [CI]=21.1–68.9) of 20 patients achieved partial response and 17 (85.0%, 95% CI=67.9–100.0) of 20 patients achieved disease control. The median progression-free survival was 8.7 months (95% CI=5.3–11.6).The incidence of adverse events (any grade) was 100%, and the incidence of grade 3–4 adverse events was 54.5%. Conclusion Anlotinib combined with etoposide emerged effective for the treatment of PROC.

Objective　To investigate the changes in expression and diagnostic value of miRNA-424-5p and interleukin-6 (IL-6) in patients with latent tuberculosis (LTBI) and active tuberculosis (ATB). Methods Data from the miRNA expression microarray GSE25435 and GSE29190 were downloaded from the U.S. National Center for Biotechnology Information Gene Expression Omnibus (GEO) database, and differentially expressed miRNA were obtained using the GEO2R tool. A total of 30 cases, including LTBI and ATB patients, were selected from the Sixth People's Hospital of Nantong between July 2022 to July 2023, with healthy controls (HC) being concurrent healthy individuals. The expression of miRNA and IL-6 in peripheral blood mononuclear cells (PBMCs) among three groups was verified by real-time fluorogenic quantitative PCR (qPCR). The diagnostic efficacy of candidate miRNA and IL-6 was evaluated by receiver operating characteristic (ROC) curves. Results By GEO2R analysis, three differential miRNAs were obtained: miRNA-424-5p, miRNA-21-3p, and miRNA-144-3p. qPCR experiments verified the levels of these three miRNAs and IL-6, showing that miRNA-21-3p and miRNA-144-3p exhibited no significant difference in relative expression in PBMCs of ATB patients compared to the LTBI group (F=6.53, P>0.05; F=3.21, P>0.05). However, the expression levels of miRNA-424-5p and IL-6 in PBMCs were significantly increased, with statistically significant differences (F=5.35, P<0.01; F=8.77, P<0.01). ROC curve analysis showed that the maximum AUC of miRNA-424-5p and IL-6 for distinguishing ATB from LTBI was 0.70 and 0.76 respectively, and their combined diagnostic AUC could reach 0.84. Conclusions The combined diagnosis of miRNA-424-5p and IL-6 has the potential to distinguish LTBI from ATB patients, providing a certain reference for the rapid differential diagnosis of latent infection and active tuberculosis.

BACKGROUND: Lung cancer is a disease with a high incidence rate in Yunnan province, yet there is a paucity of large-scale studies on its clinical epidemiology. This research aims to investigate the epidemiological characteristics of patients who underwent lung cancer surgery at Yunnan Cancer Hospital over the past decade, thereby providing a theoretical basis for the prevention and treatment of lung cancer. METHODS: Clinical data were collected from 15,967 patients who underwent lung cancer surgery at Yunnan Cancer Hospital between 2013 and 2022. A statistical analysis was conducted on the patients' general data, surgical information, pathological types of lung cancer, and other clinical epidemiological characteristics. RESULTS: Among the 15,967 cases of lung cancer, 46.3% were male and 53.7% were female, with the male-to-female ratio ranging from 0.68 to 1.61:1. The median age was 56 years (interquartile range: 49-63), and 37.0% of the patients were in the age group of 50-59 years. Since 2017, there has been an annual increase in the proportion of patients under the age of 60 years. The smoking status of the patients showed that 28.1% were smokers and 71.9% were non-smokers. Qujing city accounted for 41.4% and Kunming city for 23.2% of the cases in Yunnan province, with 29.6% of patients originating from Xuanwei and Fuyuan areas of Qujing city. The distribution of affected lung lobes was as follows: right upper lobe 28.2%, right middle lobe 6.3%, right lower lobe 20.1%, left upper lobe 22.7%, and left lower lobe 16.4%. The use of thoracoscopic surgery increased from 30.8% to 96.3%, with single-port thoracoscopic surgery comprising 61.3%. Lobectomy was performed in 64.2% of cases, wedge resection in 17.2%, and segmentectomy in 12.2%. The proportion of lobectomy decreased from 83.1% to 46.1%. The proportion of patients in stages 0-I increased from 43.5% to 82.8%, while stages II-IV decreased from 56.5% to 17.2%. Adenocarcinoma increased from 75.6% to 88.3%, and squamous cell carcinoma decreased from 21.5% to 8.6%. Among adenocarcinoma patients, 60.9% were female. Among sguamous cell carcinoma patients, 90.6% were male. The peak age for adenocarcinoma was 50-59 years, and for squamous cell carcinoma, it was 60-69 years. The smoking rate was higher among squamous cell carcinoma patients (65.9%) compared to adenocarcinoma patients (22.3%). Adenocarcinoma patients had a higher proportion in stages 0-I (76.3%), while squamous cell carcinoma patients were more prevalent in stages II-III (64.1%). CONCLUSIONS The findings indicate an increasing proportion of female patients with adenocarcinoma, a younger age of onset, a higher proportion of non-smoking lung cancer patients, and an increased proportion of stages 0-I lung cancer. These trends may reflect the epidemiological characteristics of patients undergoing lung cancer surgery in Yunnan and surrounding areas over the past decade.

OBJECTIVETo investigate the relationship between miR-501-5p expression and the clinicopathological factors in patients with lung adenocarcinoma in Xuanwei area.

METHODSSurgical specimens of lung adenocarcinoma and paired adjacent tissues from 24 patients with lung adenocarcinoma from Xuanwei area were examined for miR-501-5p expression using microRNA microarray technique and qPCR. Chi-square test was used to analyze the association of miR-501-5P expression with the clinicopathological characteristics of the patients. Multiple regression analysis was performed to analyze the association of miR-501-5p expression with the patients' gender, age, tumor stage, and preoperative CEA level.

RESULTSMicroRNA microarray analysis and qPCR validation results revealed significantly upregulated expressions of miR-501-5p in patients with lung adenocarcinoma from Xuanwei area (Plt;0.01). The microarray data showed an up-regulation of miR-501-5p by 3.17 folds in lung adenocarcinoma tissue compared with the adjacent tissue (P=0.22376, FDR=0.071395). Chi-square test indicated that miR-501-5p expression level was associated with the patients' age (f=7.168, P=0.014), TNM stage (f=36.627, P<0.01), and preoperative serum CEA level (f=30.045, Plt;0.01), but not with the patients' gender (f=3.612, P=0.071). Multiple regression analysis revealed that miR-501-5p expression was positively correlated with the patients' age, TNM stage of the tumor, and serum CEA (Plt;0.05).

CONCLUSIONmiR-501-5p expression is up-regulated in lung adenocarcinoma with significant associations with the patients' age, TNM stages and serum CEA level in patients from Xuanwei area, suggesting its potential role in the tumorigenesis and progression of lung adenocarcinoma in Xuanwei area.

Objective To explore the clinical characteristics of and to provide help to the prevention and treatment of malignant chest tumor with nosocomial mixed fungal-bacterial infection.Methods From July 2007 to June 2015,pathogenic bacteria in sputum,blood,urine,chest incision,thoracic and abdominal fluid,and implantable medical biological material were cultivated in 5067 patients with malignant chest tumor suspected with infection.The clinical characteristics,source of specimen and pathogenic bacteria,the types of diseases,medical intervention activities of 142 cases detected with mixed fungal-bacterial infection were retrospectively analyzed.Fesult In 142 patients,104 patients at clinical stage Ⅲ-Ⅳ accounted for 73.2％,and 94 patients used antibiotics more than 14 days (66.2％);104 cases had implanted biological materials (74.7％);96 cases died (67.6％).A total of 167 strains bacteria were isolated.Sixty-one strains of G+ bacteria accounting for 36.5％ were mainly Epidermis staphylococcus and Staphylococcus aureus;106 strains of G-bacteria accounting for 63.5％ were mainly klebsiella pneumonia,Escherichia coli and baumanii;172 strains fungus mainly of Candida albicans were isolated (77.3％).Pathogenic bacteria sources were mainly sputum specimens + pharynx strip,blood culture and medical implant materials.In 72 lung cancer patients,squamous carcinoma and small cell carcinoma were 52.8％ and 33.3％ respectively,higher than adenocarcinoma (12.5％);In 42 esophageal cancer patients,postoperative patients were 42.9％.Parenteral nutrition patients with more than 10 days were 80.9％ higher than that of parenteral nutrition in patients with less than 10 days (19.1％).Conclusion Among malignant chest tumor patients with nosocomial mixed fungal-bacterial infection,the bacteria were found in staphylococcus aureus,klebsiella pneumoniae and E.coli and the fungus was Candida albicans.For clinical stage Ⅲ-Ⅳ,patients with parenteral nutrition for more than 10 days,having history of chemo or radiotherapy,with antimicrobial use for more than 14 days,and with implanted biological materials,should be warned about nosocomial mixed fungal-bacterial infection.
