after 10 years. Large population-based studies are needed to validate that high reimbursement insurance status can lead to the improvement of long-term cancer prognosis in China.
To investigate histo-pathological distribution and clinico-pathological significance in a large Chinese triple-negative breast cancer (TNBC) patients serials based on the latest understanding of its clinico-pathological diversity, and to provide more information to clinicians to improve precision of individualized treatment of TNBC.
A retrospective analysis was performed on patients with TNBC at Breast Disease Center, Peking University First Hospital between January 2010 and December 2019. Histo- and clinico-pathological characteristics were analyzed by Chi-square test and Student’s
-test, and prognoses were calculated using Kaplan-Meier method and a Cox proportionate hazards model. Bonferroni correction was used to correct for multiple comparison.
Conventional type of TNBC (cTNBC) were identified in 73.7% of 582 TNBC, while special type of TNBC (sTNBC) were 26.3%, including 71 apocrine carcinoma, 20 medullary carcinoma, 31 metaplastic carcinoma, 18 invasive lobular carcinoma, 7 invasive micropapillarbe meaningful in pathological evaluation of TNBC, and need to be clarified in more large collections of TNBC.
Although T-cell immunoglobulin and mucin-domain containing molecule-3 (Tim-3) has been recognized as a promising target for cancer immunotherapy, its exact role in breast cancer has not been fully elucidated.
gene expression in breast cancer and its prognostic significance were analyzed. c-RET inhibitor Associated mechanisms were then explored
by establishing Tim-3-overexpressing breast cancer cells.
In a pooled analysis of The Cancer Genome Atlas (TCGA) database,
gene expression levels were significantly higher (P<0.001) in breast cancer tissue, compared with normal tissues. Tim-3 was a prognosis indicator in breast cancer patients [relapse-free survival (RFS), P=0.004; overall survival (OS), P=0.099]. Tim-3 overexpression in Tim-3
breast cancer cells promoted aggressiveness of breast cancer cells, as evidenced by enhanced proliferation, migration, invasion, tight junction deterioration and tumor-associated tubal formation. Tim-3 also enhanced cellular resistance to paclitaxel. Furthermore, Tim-3 exerted its function by activating the NF-κB/STAT3 signalling pathway and by regulating gene expression [cyclin D1 (
),
, matrix metalloproteinase-1(
),
, vascular endothelial growth factor (
) upregulation, concomitant with
downregulation). Lastly, Tim-3 downregulated tight junction-associated molecules zona occludens (ZO)-2, ZO-1 and occludin, which may further facilitate tumor progression.
Tim-3 plays an oncogenic role in breast cancer and may represent a potential target for antitumor therapy.

Solute carrier family 38 (SLC38s) transporters play important roles in amino acid transportation and signaling transduction. However, their genetic alterations and biological roles in tumors are still largely unclear. This study aimed to elucidate the genetic signatures of SLC38s transporters and their implications in esophageal squamous cell carcinoma (ESCC).
Analyses on somatic mutation and copy number alterations (CNAs) of SLC38A3 were performed as described. Immunohistochemistry (IHC) assay and Western blot assay were used to detect the protein expression level. MTS assay, colony formation assay, transwell assay and wound healing assay were used to explore the malignant phenotypes of ESCC cells. Immunofluorescence assay was used to verify the colocalization of two indicated proteins and immunopreciptation assay was performed to confirm the interaction of proteins.
Our findings revealed that SLC38s family was significantly disrupted in ESCC, with high frequent CNAs and few somatic mutations.
was the most frequent loss gene among them and was linked to poor survival and lymph node metastasis. The expression of SLC38A3 was lower in tumor tissues compared to that in normal tissues, which was also significantly associated with worse clinical outcome. Further experiments revealed that depletion of SLC38A3 could promote EMT in ESCC cell lines, and the interaction of SLC38A3 and SETDB1 might lead to the reduced transcription of Snail. Pharmacogenomic analyses demonstrated that fifteen inhibitors were showed significantly correlated with SLC38A3 expression.
Our investigations have provided insights that SLC38A3 could act as a suppressor in EMT pathway and serve as a prognostic factor and predictor of differential drug sensitivities in ESCC.

In an attempt to slow the spread of the virus nationwide lockdown restrictions were introduced. This review aims to scope the literature on the impact of the pandemic and subsequent lockdown on the presentation and management of trauma globally. Methods; A scoping review was conducted in accordance with PRISMA-ScR guidelines. A systematic search was carried out on the Medline, EMBASE and Cochrane databases to identify papers investigating presentation and management of trauma during the COVID-19 pandemic. All studies based on patients admitted with orthopaedic trauma during the COVID-19 pandemic were included. Exclusion criteria were opinion-based reports, reviews, studies that did not provide quantitative data and papers not in English. Results; 665 studies were screened, with 57 meeting the eligibility criteria. Studies reported on the footfall of trauma in the Ue delivery of effective trauma care despite resource constraints during this global COVID-19 pandemic.The pandemic of COVID-19 across the globe triggered national lockdowns hampering normal working for all the essential services including healthcare. In order to reduce transmission and safety of patients and healthcare workers, the elective surgeries have been differed. The visits to the hospitals for follow-ups and consultations received temporary halt. However, we cannot halt the treatment for cancer patients who may or may not be COVID-19 positives. These are emergencies and should be treated ASAP. Conducting emergency surgeries during pandemic like COVID-19 is challenge for surgeons and the entire hospital infrastructure. The available information about COVID-19 and its propensity of contamination through droplets and aerosol need some modifications for conducting surgeries successfully without contaminating the hospital buildings, protecting healthcare teams and the patient. With these objectives, some modifications in the operating theater including surgical techniques for minimal access, laparoscopy, and robotic surgery are proposed in this review article.
