Metastasis serves as an indicator of malignancy and is a biological characteristic of carcinomas. Epithelial-mesenchymal transition (EMT) plays a key role in the promotion of tumor invasion and metastasis and in the enhancement of tumor cell aggressiveness. Prostaglandin E synthase 3 (p23) is a cochaperone for heat shock protein 90 (HSP90). Our previous study showed that p23 is an HSP90-independent transcription factor in cancer-associated inflammation. The effect and mechanism of action of p23 on lung cancer metastasis are tested in this study. By utilizing cell models in vitro and mouse tail vein metastasis models in vivo, the results provide solid evidence that p23 is critical for promoting lung cancer metastases by regulating downstream CXCL1 expression. Rather than acting independently, p23 forms a complex with RNA-binding motif protein 14 (RBM14) to facilitate EMT progression in lung cancer. Therefore, our study provides evidence for the potential role of the RBM14-p23-CXCL1-EMT axis in the metastasis of lung cancer.

Elemene is widely recognized as an effective anti-cancer compound and is routinely administered in Chinese clinical settings for the management of several solid tumors, including non-small cell lung cancer (NSCLC). However, its detailed molecular mechanism has not been adequately demonstrated. In this research, it was demonstrated that elemene effectively curtailed NSCLC growth in the patient-derived xenograft (PDX) model. Mechanistically, employing high-throughput screening techniques and subsequent biochemical validations such as microscale thermophoresis (MST), microRNA-145-5p (miR-145-5p) was pinpointed as a critical target through which elemene exerts its anti-tumor effects. Interestingly, elemene serves as a binding stabilizer for miR-145-5p, demonstrating a strong binding affinity (dissociation constant (K _D) = 0.39 ± 0.17 μg/mL) and preventing its degradation both in vitro and in vivo, while not interfering with the synthesis of the primary microRNA transcripts (pri-miRNAs) and precursor miRNAs (pre-miRNAs). The stabilization of miR-145-5p by elemene resulted in an increased level of this miRNA, subsequently suppressing NSCLC progression through the miR-145-5p/mitogen-activated protein kinase kinase kinase 3 (MAP3K3)/nuclear factor kappaB (NF-κB) pathway. Our findings provide a new perspective on revealing the interaction patterns between clinical anti-tumor drugs and miRNAs.

Objective:To learn about the status quo and hotspots in the field of health policy research under the concept of One Health.Methods:The Web of Science Core Collection (WoS) database and China National Knowledge Infrastructure (CNKI) database from 2001 to 2020 were searched for publications in the field of health policy research under the concept of One Health. A total of 3 515 publications in English and 42 in Chinese were included, CiteSpace 5.6.R3 software was used to analyze the number of publications, countries, institutions, authors, and keywords, and to draw visual maps.Results:The number of publications in WoS database was 52 in 2001 and 500 in 2020, with an overall upward trend in the number of publications; the first relevant publication in CNKI database was published in 2009, and the number of publications increased to 13 by 2020, but the total number was still low (42). Among the countries, the USA had the highest number of publications (1 385), total citations (48 780) and highly cited (≥10 citations) publications (671). Switzerland had the highest citations per publication (89.72). China ranked 5th in the number of publications (160) and 8th in total citations (4 643) and citations per publication (29.02), with fewer highly cited publications (82). The English author partnership had a large collaborative team led by Chris Degeling at the University of Sydney; the Chinese author partnership had a large research team led by Lu Jiahai at the School of Public Health, Sun Yat-sen University. In terms of country cooperation, French node had the largest centrality (0.30), the centrality of Chinese nodes was 0.01. Emerging infectious diseases, zoonose, and antibiotic resistance were high-frequency keywords in the English publications, while COVID-19, zoonose, antibiotic resistance, and food safety were high-frequency keywords in the Chinese publications.Conclusions:From 2001 to 2020, the overall trend of the number of publications in health policy research under the concept of One Health worldwide is on the rise. Emerging infectious diseases, zoonose, antibiotic resistance, and food safety are the current research hotspots in this field.

Objective To retrospectively analyze the results of neonatal diseases screening in Yichang from 2017 to 2019, understand the incidence and recall of the diseases, and explore the management mode of neonatal disease screening suitable for this region. Methods The subjects were newborns who were delivered in Yichang midwifery institutions from 2017 to 2019 and were screened for neonatal diseases. Heel blood of the newborns was collected for the screening of neonatal diseases, including congenital hypothyroidism (CH), phenylketonuria (PKU), G6PD deficiency, congenital adrenal hyperplasia (CAH) and thalassemia. Those newborns with positive initial screening were recalled for reexamination and confirmation. The recall rates of different diseases were compared by Chi-square test. Results There were 85 891 live births in Yichang area from 2017 to 2019, and 84 063 cases were screened for neonatal diseases, with a screening rate of 97.87%. A total of 6 043 cases were positive in the initial screening, of which 5,047 cases were recalled, with a recall rate of 83.52%. The recall rates of the traditional two diseases (CH and PKU) and the new three diseases (CAH, G6PD deficiency and thalassemia) were significantly different ( χ²= 197.93, P＜0.01). A total of 501 cases were diagnosed. The incidence rate of CH was 1/1,911, the incidence rate of PKU was 1/12 009, the incidence rate of CAH was 1/28 021, the incidence rate of G6PD deficiency was 1/1 121, and the incidence rate of thalassemia was 1/226. Conclusions The neonatal disease screening rate increased year by year in Yichang, but the recall rate of suspicious positive initial screenings decreased. It is necessary to explore a more suitable management mode for the five neonatal disease screenings in this region, improve the recall rate of children with positive screening, reduce the incidence of disabled children, and improve the quality of the birth population.

Objective:To understand the HIV antibody screening results among the preoperative examination patients in Beijing Tongren Hospital from 2008 to 2018.Methods:A retrospective analysis of the HIV antibody screening data of thepreoperative examination patients from 2008 to 2018 in Beijing Tongren Hospital was performed with software SPSS19.0. Trend chi-square was used to analyze the positive rate, age, marital status, household registration and so on.Results:Among the 750 013 clinical patients, 428 (0.057%) cases were screened anti-HIV positive and 370(0.049%) cases were confirmed anti-HIV positive when detected with western blotting.Most of the HIV-infectedindividuals were non-Beijing nationality, accounting for 60.27%.Among the 370 HIV-infected patients, there were 334 males (90.27%) and 36 females (9.73%). The age was distributed mainly between 20-40 years old (62.43%), secondly between 40-60 years old (28.65%).361 (97.57%)HIV-infected cases were transmitted by the sex and the MSM men increased from 2008 to 2018 (trend χ2=7.307, P=0.007). There were 22 cases (5.95%) with HBsAg positive, 11 cases (2.97%) with anti-HCV positive. Among the 159 HIV-positive patients (42.97%) companied with syphilis specific antibody positive, there were 64 cases (17.30%) with TRUST tests positive. Additionally, 178 (48.11%) HIV-infected patientsfirst visited doctors because of ocular disease in the hospital; secondly, 71 (19.19%) HIV-infected patientsfirst visited the dermatology. Conclusions:The number of HIV-infected patientsmarkedly increased from 2008 to 2018. The sexual transmission is still the main pathway for HIV infection, particularly homosexual transmission. Moreover, the results indicate that it is necessary to detect HIV antibody for the ocular disease patients.

Since the emergence in 1980s,community-associated methicillin-resistant Staphylococcus Aurues (CA-MRSA) has caught great attention of the researchers and clinical practitioners all over the world. In recent scientific papers,people found that CA-MRSA's capability to adapt itself to the hostile environment and to colonize is a kind of important virulence factor. A newly unveiled gene,designated arginine catabolic mobile element (ACME),in USA300 stains contributes much to this sort of ability. The arginine deiminase encoded by ACME plays an important role in colonization.
