Background::Triple-negative breast cancer (TNBC) is a type of highly invasive breast cancer with a poor prognosis. According to new research, long noncoding RNAs (lncRNAs) play a significant role in the progression of cancer. Although the role of lncRNAs in breast cancer has been well reported, few studies have focused on TNBC. This study aimed to explore the biological function and clinical significance of forkhead box C1 promoter upstream transcript (FOXCUT) in triple-negative breast cancer.Methods::Based on a bioinformatic analysis of the cancer genome atlas (TCGA) database, we detected that the lncRNA FOXCUT was overexpressed in TNBC tissues, which was further validated in an external cohort of tissues from the General Surgery Department of the First Affiliated Hospital of Nanjing Medical University. The functions of FOXCUT in proliferation, migration, and invasion were detected in vitro or in vivo. Luciferase assays and RNA immunoprecipitation (RIP) were performed to reveal that FOXCUT acted as a competitive endogenous RNA (ceRNA) for the microRNA miR-24-3p and consequently inhibited the degradation of p38. Results::lncRNA FOXCUT was markedly highly expressed in breast cancer, which was associated with poor prognosis in some cases. Knockdown of FOXCUT significantly inhibited cancer growth and metastasis in vitro or in vivo. Mechanistically, FOXCUT competitively bounded to miR-24-3p to prevent the degradation of p38, which might act as an oncogene in breast cancer. Conclusion::Collectively, this research revealed a novel FOXCUT/miR-24-3p/p38 axis that affected breast cancer progression and suggested that the lncRNA FOXCUT could be a diagnostic marker and therapeutic target for breast cancer.

Objective:To investigate the clinical characteristics of dermatomyositis (DM) patients with positive anti-melanoma differentiation-associated protein 5 (MDA5) antibody-complicated with pneumomediastinum.Methods:Clinical data of patients with anti-MDA5 antibody-positive DM with or without pneumomediastinum from March 2017 to December 2019 in Ningbo First Hospital were collected and analyzed. The international literature were reviewed and compared. T-test or Mann-Whitney U test was used for measurement data, chi-square test or Fisher exact probability was used for count data. Logistic regression analysis was used to analyze the risk factors for anti-MDA5 antibody-positive DM with pneumomediastinum. Results:Twelve DM patients with -positive anti-MDA5 antibody without pneumomediastinum, and 1 DM patient with positive anti-MDA5 antibody-complicated with pneumomediastinum. Pooling with literature review, 16 DM patients with positive anti-MDA5 antibody-complicated with pneumomediastinum were compared. It was found that the serum ferritin (SF) level [991.6(548.5, 2875.1) ng/ml vs 355 (143.5, 395) ng/ml, Z=-2.506, P=0.012] and the rate of rapid progressive pulmonary interstitial disease (RPILD) in the pneumo-mediastinum group [76.5% vs 16.7%, χ2=10.076, P=0.002] were significantly higher than those in the non-pneumome-diastinum group. Further Logi-stic regression analysis did not show male gender [ OR=0.192, 95% CI(0.009, 4.125), P=0.291]; SF [ OR=1.002, 95% CI(0.998, 1.006), P=0.279]; RPILD[ OR=0.084, 95% CI(0.003, 2.178), P=0.136]; CADM[ OR=0.258, 95% CI(0.009, 7.419), P=0.429] was risk factor for pneumomediastinum. Conclusion:DM patients with positive anti-MDA5 antibody and high seral SF level and rapid progression of pulmonary interstitial disease are more likely to complicate with pneumomediastinum.

Pancreatic cancer has poor prognosis and lymph node metastasis is a poor prognostic factor in patients with resectable pancreatic cancer. The metastatic prevalence of para-aortic lymph node (PALN) ranges from 9.1% to 26.5% and it is listed as the distant metastatic group in pancreatic cancer. Nevertheless, it is controversial whether PALN metastasis is the contraindication of surgery in resectable pancreatic cancer for the shortage of level Ⅰ evidence.This study concluded that PALN metastasis indicated poor prognosis in patients with pancreatic cancer, but some patients with PALN metastases could benefit from surgery and their survival could be much improved after the combination of surgery and adjuvant therapy. Therefore, it is not wise to refuse surgery for all pancreatic cancer patients with PALN metastasis and the clinicians can cautiously choose the patients to do surgery. Besides, there are mainly retrospective studies rather than prospective and multicenter studies to explore the prognosis of pancreatic cancer patients with PALN metastasis. Thus, more prospective and multicenter studies are needed to decide whether PALN metastasis is an independent prognostic factor in patients with resectable pancreatic cancer.

Cystic echinococcosis (CE) caused by E. granulosus is a serious helminthic zoonosis in humans, livestock and wildlife. Xinjiang is one of high endemic province for CE in China. A total of 55 sheep and cattle livers containing echinococcal cysts were collected from slaughterhouses in Changji and Yining City, northern region of Xinjiang. PCR was employed for cloning 2 gene fragments, 12S rRNA and CO1 for analysis of phylogenetic diversity of E. granulosus. The results showed that all the samples collected were identified as G1 genotype of E. granulosus. Interestingly, YL5 and CJ75 strains were the older branches compared to those strains from France, Argentina, Australia. CO1 gene fragment showed 20 new genotype haploids and 5 new genotype haplogroups (H1-H5) by the analysis of Network 5.0 software, and the YLY17 strain was identified as the most ancestral haplotype. The major haplotypes, such as CJ75 and YL5 strains, showed identical to the isolates from Middle East. The international and domestic trade of livestock might contribute to the dispersal of different haplotypes for E. granulosus evolution.

OBJECTIVE To explore the effect of aqueous extract of Zheng Chaihu Yin(ZCH)on paracetamol(acetaminophen,APAP)-induced hepatotoxicity. METHODS Male ICR mice were divided into three scenarios randomly:the single treatment dose of ZCH,multiple treatment or pretreatment dose of ZCH. Each scenario had a up control group and an APAP model group,while single treatment dose of ZCH group had a ZCH group at the same time. The dose of APAP and ZCH was 500 mg·kg-1 and 36 g · kg- 1,respectively. 24 h after the last administration,plasma and liver samples were prepared. Ultra- performance liquid chromatography/quadrupole- time- of- flight mass spectrometry (UPLC-Q-TOF-MS)based metabolomics profiling was used to examine changes in plasma after expo?sure to ZCH,APAP or co-exposure to ZCH and APAP. Glutamic pyruvic transaminase (GPT) and glutamic oxaloacetic transaminas (GOT) values were determined by a biochemical auto analyzer in plasma. Histopathologic changes in the liver were observed and the area was calculated after HE staining. The data were analyzed with SPSS16.0 statistical software and the results were compared with the test between the two groups to find biomarkers. Also,SIMCA software was used for partial least squares-discriminant analysis (PLS-DA) pattern recognition. RESULTS Compared to control group, APAP dosing alone caused an increase in plasma transaminases and alterations in multiple metabolic pathways. Compared to APAP group,decrease in plasma transaminases was noted when ZCH was administered after or prior to APAP. Histopathologic results showed that in the single treatment group, multiple treatment group and pretreatment group,ZCH could alleviate the liver damage induced by APAP from (32.3 ± 12.0)% to (14.2 ± 9.9)%,(8.6 ± 7.9)% to (5.2 ± 1.7)% and (32.5 ± 10.0)% to (5.2 ± 6.4)%(P<0.05). Similarly,the PLS-DA of the LC-MS data showed that the groups dosed with APAP alone were the most distinct from controls,while animals dosed with ZCH prior to or after APAP treatment were located near control group. Metabolic spectrum results showed that ZCH could restore the changes in endogenous substances including lipid metabolism,amino acid metabolism,sugar metabolism and energy metabolism induced by APAP to normal. CONCLUSION ZCH water-extraction plays major roles in the regulation of metabolism on APAP-induced liver injury. These studies demonstrate that UPLC-Q-TOF-MS-based metabolomic analysis can be sensitively and accurately predict the initiation and progres?sion of liver injury and greatly contribute to a better understanding of the hepatoprotective effects of ZCH in a clinical environment.

Objective To analyze risk factors of Swan-Ganz catheter-related bloodstream infections ( CRBSI) in patients with severe heart disease in Cardiac Care Unit ( CCU) . Methods A total of 768 patients undergoing indwelling Swan-Ganz catheterization in CCU between January 2013 to December 2014 were enrolled in this study. Bacterial culture of blood in catheter and catheter tip that 5 cm distance from distal end were performed if the patients were suspected of intravascular catheter-related infections or the catheter was removed from the patients for more than 7 days. Results During 3050 catheter days, 23 of 768 patients were diagnosed of CRBSI(7. 5 ‰), and the infection rate was about 3%. The top 5 pathogenic bacteria were staphylococcus aureus, staphylococcus haemolyticus, staphylococcus epidermidis, albicans saccharomyces and klebsiella pneumoniae. The patient′s gender, ages, with diabetes or not, and usage of antibiotic during catheterization had no correlation with catheter related infection (P >0. 05), but the skin of whole body clean or not before catheterization, the length of catheterization had correlation with catheter related infection ( P < 0. 05 ). Multivariate logistic regression analysis showed that the whole bode skin clean before catheterization was the protective factor for CRBSI, and long catheter indwelling time and combined antibiotic treatment during catheterization were the risk factors for CRBSI (P<0. 05). Conclusions The incidence of CRBSI in patients with severe heart disease is related to the catheter indwelling time, and skin clean before indwelling which are able to effectively reduce the incidence of CRBSI. Antibiotic treatment during catheterization is not beneficial for decreasing the incidence of CRBSI.

Hedgehog pathway is an osteogenesis-related signaling pathway . During embryonic development , it regulates the growth and proliferation of progenitor cells and tissue formation. This pathway can be activated during liver injury. Activated Hedge-hog signaling pathway is involved in many aspects of liver wound-healing responses, including hepatic progenitor cell pro-liferation, myofibroblast transdifferentiation, apoptosis of various types of liver cells, inflammatory reactions, and vascular remod-eling. This article reviews the research progress in the role of Hedgehog signaling pathway in liver injury and the underlying mechanisms. The potential drug targets are also discussed. This review is to provide novel insights into antifibrotic research and therapeutic targets.
