Objective:To explore the application value of artificial intelligence (AI) model based on deep learning in breast nodules classification of Breast Imaging Reporting and Data System of ultrasound (BI-RADS-US).Methods:The ultrasound images of 2 426 breast nodules from 1 558 female patients with breast diseases at Beijing Tongren Hospital, Capital Medical University between December 2006 and December 2019 were collected . The image data sets were divided into training (63%), verification (7%), and test (30%) subsets for the construction of AI model. The diagnostic efficiencies of AI model, doctors' arbitration results and doctors' diagnosis with or without AI model assistance were analyzed by using receiver operating characteristic (ROC) curve. The Cohen weighted Kappa statistic was used to compare the consistency of BI-RADS-US classification among 5 ultrasound doctors' diagnosis with or without AI model assistance. And the changes of BI-RADS-US classification were analyzed before and after each doctor adopted AI model assistance.Results:The differences in diagnostic efficiencies of AI model, doctors' arbitration results and doctors' diagnosis with or without AI model assistance were statistically significant (all P > 0.05). The consistency among 5 ultrasound doctors was improved due to AI model assistance and Kappa value was increased from 0.433 (category 3), 0.600 (category 4a), 0.614 (category 4b), 0.570 (category 4c) and 0.495 (category 5) to 0.812, 0.704, 0.823, 0.690 and 0.509 (all P < 0.05), respectively. The upgrade and downgrade of BI-RADS-US classification occurred in 5 doctors after the classification of AI model assistance. Downgrade from category 4 to 3 in benign nodules of 56.6% (47/76) and upgrade from category 4 to 5 in malignant nodules of 69.4% (34/49) were mostly observed. Conclusions:AI-assisted BI-RADS-US classification can effectively improve the consistency of classification among the doctors without reducing the diagnostic efficiency. AI model shows clinical values in reducing unnecessary biopsy of partial benign lesions and increasing diagnostic accuracy of partial malignant lesions through the adjustment of breast nodule classification.

Objective: To investigate the serotype distribution and antimicrobial susceptibility pattern of Streptococcus pneumoniae (S. pneumoniae), Haemophilus influenzae (H. influenzae) and Moraxella catarrhalis (M. catarrhalis) isolates collected from nasopharyngeal swabs from Uygur children in Kashi. Methods: Nasopharyngeal swabs were collected from inpatient Uygur children aged from 1 month to 5 years with respiratory infections from the pediatric department, the First People's Hospital of Kashi, Xinjiang Uygur Autonomous Region. Antimicrobial susceptibilities of the isolates were determined with E-test and KB disk diffusion methods. The production of β-lactamase was detected for H. influenzae and M. catarrhalisisolates using nitrocefin disc method. Quellung test and latex agglutination test were adopted to identify serotypes of S. pneumoniae and H. influenzae isolates. Results: Forty-seven S. pneumoniae, 13 H. influenzae and 16 M. catarrhalis isolates were detected. All of the 47 S. pneumoniae isolates were sensitive to parenteral penicillin, amoxicillin-clavulanic acid, vancomycin and levofloxacin; the susceptibility rates to cefotaxime, imipenem and chloramphenicol were 94% (44/47), 89% (42/47), and 98% (46/47). The resistance rate to erythromycin was 74% (35/47). The most common serotype of S. pneumoniae was serotype 19A (10 strains, 21%). The coverage rate of 13-valent conjugate vaccine (PCV13) was 70% (33/47). None of the 13 H. influenzae isolates could be typed. They were highly susceptible to tested β-lactams antibiotics, except ampicillin. Only one H. influenzae isolate could produce β-lactamase, and two isolates were identified as β-lactamase-negative-ampicillin-resistant ones. The sixteen M. catarrhalis isolates were all positive in β-lactamase detection, but sensitive to amoxicillin-clavulanic acid, cephalosporins and meropenem. Conclusions In Kashi, Xinjiang Uygur Autonmous Region, S. pneumoniae isolates from Uygur children were highly sensitive to parenteral penicillin and other β-lactams antibiotics. H. influenzae isolates from Uygur children were highly susceptible to amoxicillin-clavulanic acid, cephalosporins and ciprofloxacin. All M. catarrhalis isolates from Uygur children could produce β-lactamase, but were sensitive to the enzyme inhibitors and cephalosporins.

OBJECTIVE: To explore the mechanism by which ginsenoside 20(S)-Rg3 upregulates the expression of tumor suppressor von Hippel-Lindau (VHL) gene in ovarian cancer cells. METHODS: Ovarian cancer cell line SKOV3 treated with 20(S)-Rg3 were examined for mRNA and protein levels of VHL, DNMT1, DNMT3A and DNMT3B by real-time PCR and Western blotting, respectively. The changes in VHL mRNA expression in SKOV3 cells in response to treatment with 5-Aza-CdR, a DNA methyltransferase inhibitor, were detected using real-time PCR. VHL gene promoter methylation was examined with methylation-specific PCR and VHL expression levels were determined with real-time PCR and Western blotting in non-treated or 20(S)-Rg3-treated SKOV3 cells and in 20(S)-Rg3-treated DNMT3A-overexpressing SKOV3 cells. VHL and DNMT3A protein levels were detected by immunohistochemistry in subcutaneous SKOV3 cell xenografts in nude mice. RESULTS: Treatment of SKOV3 cells with 20(S)-Rg3 significantly upregulated VHL and downregulated DNMT3A expressions at both the mRNA and protein levels ( CONCLUSIONS Ginsenoside 20(S)-Rg3 upregulates VHL expression in ovarian cancer cells by suppressing DNMT3A-mediated DNA methylation.

Hepatic stellate cells (HSCs) represent a significant component of hepatocellular carcinoma (HCC) microenvironments which play a critical role in tumor progression and drug resistance. Tumor-on-a-chip technology has provided a powerful in vitro platform to investigate the crosstalk between activated HSCs and HCC cells by mimicking physiological architecture with precise spatiotemporal control. Here we developed a tri-cell culture microfluidic chip to evaluate the impact of HSCs on HCC progression. On-chip analysis revealed activated HSCs contributed to endothelial invasion, HCC drug resistance and natural killer (NK) cell exhaustion. Cytokine array and RNA sequencing analysis were combined to indicate the iron-binding protein LIPOCALIN-2 (LCN-2) as a key factor in remodeling tumor microenvironments in the HCC-on-a-chip. LCN-2 targeted therapy demonstrated robust anti-tumor effects both in vitro 3D biomimetic chip and in vivo mouse model, including angiogenesis inhibition, sorafenib sensitivity promotion and NK-cell cytotoxicity enhancement. Taken together, the microfluidic platform exhibited obvious advantages in mimicking functional characteristics of tumor microenvironments and developing targeted therapies.
