Here we demonstrate that miRNAs are present in the serum and plasma of humans and other animals such as mice, rats, bovine fetuses, calves, and horses. The levels of miRNAs in serum are stable, reproducible, and consistent among individuals of the same species. Employing Solexa, we sequenced all serum miRNAs of healthy Chinese subjects and found over 100 and 91 serum miRNAs in male and female subjects, respectively. We also identified specific expression patterns of serum miRNAs for lung cancer, colorectal cancer, and diabetes, providing evidence that serum miRNAs contain fingerprints for various diseases. Two non-small cell lung cancer-specific serum miRNAs obtained by Solexa were further validated in an independent trial of 75 healthy donors and 152 cancer patients, using quantitative reverse transcription polymerase chain reaction assays. Through these analyses, we conclude that serum miRNAs can serve as potential biomarkers for the detection of various cancers and other diseases.展开更多

Eligible patients with HER2-positive （〉50%） BTCs and PCs were enrolled in the trial. Well cultured CART-HER2 cells were infused following the conditioning treatment composed of nab- paclitaxel （100-200 mg/m2） and cyclophosphamide （15-35 mglkg）. CAR transgene copy number in the peripheral blood was serially measured to monitor the expansion and persistence of CART-HER2 cells in vivo. Eleven enrolled patients received 1 to 2-cycle CART- HER2 cell infusion （median CAR＋ T cell 2.1× 10^6/kg）. The conditioning treatment resulted in mild-to-moderate fatigue, nausea/vomiting, myalgialarthralgia, and lym- phopenia. Except one grade-3 acute febrile syndrome and one abnormal elevation of transaminase （〉9 ULN）, adverse events related to the infusion of CART-HER2 cells were mild-to-moderate. Post-infusion toxicities included one case of reversible severe upper gastroin- testinal hemorrhage which occurred in a patient with gastric antrum invaded by metastasis 11 days after the CART-HER2 cell infusion, and 2 cases of grade 1-2delayed fever, accompanied by the release of C-reactive protein and interleukin-6. All patients were evaluable for assessment of clinical response, among which 1 obtained a 4.5-months partial response and 5 achieved stable disease. The median progression free survival was 4.8 months （range, 1.5-8.3 months）. Finally, data from this study demonstrated the safety and feasibility of CART-HER2 immunotherapy, and showed encourag- ing signals of clinical activity.展开更多

They play profound and pervasive roles in manipulating gene expression involved in cell development, proliferation and apoptosis in various eukaryotes, which, in theory, could provide an access to many human diseases in theory. Recent evidence demonstrates that aberrant miRNA expression is a hallmark of tumor development, revealing that miRNA genes could function as potential oncogenes and repressors in the human body. miRNAs can affect tumorigenesis mainly by interrupting the cell cycle at the cellular level and by interacting with signaling, oncogenes and with the response to environmental factors at the molecular level. The established miRNA expression signature could be a potent tool to diagnose and treat human cancers in the future.展开更多

This review was aimed at looking for appropriate biomarkers for the treatment of diseases.Data sources:The comprehensive search used online literature databases including PubMed of National Center for Biotechnology Information and Web of Science.Study selection:The study selection was based on the following keywords: circRNAs, biogenesis, biologic function, and disease. The time limit for literature retrieval was from the year 1976 to 2019, with language restriction in English. Relevant articles were carefully reviewed, with no exclusions applied to study design and publication type.Results:CircRNAs are one of the critical non-coding RNAs (ncRNAs), which are covalently closed continuous loops that do not possess 5' and 3' ends. This makes them resistant to exoribonuclease activity and potentially more stable than their cognate linear transcripts, thus making them ideal candidates for biomarker development. Due to the stable and extensive tissue-specific expression of circRNAs, they can function as microRNA sponges and bind to RNA-binding proteins, regulate transcription and splicing, and translate into proteins to participate in the regulation of physiologic and pathologic processes. Moreover, the expression disorders of circRNAs in diseases, such as neurodegenerative disease, cardiovascular disease, and cancer, make them have potential applications for the diagnosis and treatment of diseases.Conclusions:Changes in circRNA expression profiles related to various diseases, and circRNAs often exhibit low expression in cancer tissues. In addition, circRNAs can be detected in patient’s body fluids to indicate that circRNAs are effective biomarkers for disease diagnosis. These characteristics make circRNAs have potential applications as novel therapeutic targets for diseases.展开更多

We estimated numbers of primary bone cancer cases and deaths in China using age-specific rates and corresponding national population stratified by area,sex, age-group(0, 1-4, 5-9, 10-14, …, 85+). Chinese standard population in 2000 and Segi's World population were applied for the calculation of age-standardized incidence and mortality rates.Results: In 2014, 24,000 primary bone cancer cases and 17,200 deaths attributable to primary bone cancers were estimated to have occurred in China. The crude incidence rate of primary bone cancers was 1.76/100,000, with agestandardized incidence rate by Chinese standard population(ASIRC) and by World standard population(ASIRW)being 1.35/100,000 and 1.32/100,000, respectively. The crude mortality rate of primary bone cancers was1.26/100,000, with age-standardized mortality rate by Chinese standard population(ASMRC) and by World standard population(ASMRW) being 0.88/100,000 and 0.86/100,000, respectively. Age-specific incidence curve was bimodally distributed with age, with the first peak occurring in the second decade of the life and the second peak in the elderly. Males had higher crude and age-standardized rates for both incidence and mortality compared with females. Both crude and age-standardized incidence rates were higher in rural areas than in urban areas, so were the crude and age-standardized mortality rates.Conclusions: This population-based study presents the most recently available estimates on primary bone cancers in China, revealing that the males are 1.34 times as much as females suffering from primary bone cancers and the adolescents in puberty and the el展开更多

With the latest breakthroughs in molecular biology and immunotherapy, very specific targeted therapies have been tailored to the specific pathophysiology of different types of breast cancers. These recent developments have contributed to a more efficient and specific treatment protocol in breast cancer patients. However, the main challenge to be further investigated still remains the emergence of therapeutic resistance mechanisms, which develop soon after the onset of therapy and need urgent attention and further elucidation. What are the recent emerging molecular resistance mechanisms in breast cancer targeted therapy and what are the best strategies to apply in order to circumvent this important obstacle? The main scope of this review is to provide a thorough update of recent developments in the field and discuss future prospects for preventing resistance mechanisms in the quest to increase overall survival of patients suffering from the disease.展开更多

文摘Breast cancer is the most common type of cancer found in women and today represents a significant challenge to public health. With the latest breakthroughs in molecular biology and immunotherapy, very specific targeted therapies have been tailored to the specific pathophysiology of different types of breast cancers. These recent developments have contributed to a more efficient and specific treatment protocol in breast cancer patients. However, the main challenge to be further investigated still remains the emergence of therapeutic resistance mechanisms, which develop soon after the onset of therapy and need urgent attention and further elucidation. What are the recent emerging molecular resistance mechanisms in breast cancer targeted therapy and what are the best strategies to apply in order to circumvent this important obstacle? The main scope of this review is to provide a thorough update of recent developments in the field and discuss future prospects for preventing resistance mechanisms in the quest to increase overall survival of patients suffering from the disease.

文摘BACKGROUND Obstructive colorectal cancer(OCC)is always accompanied by severe complications,and the optimal strategy for patients with OCC remains undetermined.Different from emergency surgery(ES),self-expandable metal stents(SEMS)as a bridge to surgery(BTS),could increase the likelihood of primary anastomosis.However,the stent failure and related complications might give rise to a high recurrence rate.Few studies have focused on the indications for either method,and the relationship between preoperative inflammation indexes and the prognosis of OCC is still underestimated.AIM To explore the indications for ES and BTS in OCCs based on preoperative inflammation indexes.METHODS One hundred and twenty-eight patients who underwent ES or BTS from 2008 to 2015 were enrolled.Receiver operating characteristic(ROC)curve analysis was used to define the optimal preoperative inflammation index and its cutoff point.Kaplan–Meier analyses and Cox proportional hazards models were applied to assess the association between the preoperative inflammation indexes and the survival outcomes[overall survival(OS)and disease-free survival(DFS)].Stratification analysis was performed to identify the subgroups that would benefit from ES or BTS.RESULTS OS and DFS were comparable between the ES and BTS groups(P>0.05).ROC curve analysis showed derived neutrophil-to-lymphocyte ratio(dNLR)as the optimal biomarker for the prediction of DFS in ES(P<0.05).Lymphocyte-tomonocyte ratio(LMR)was recommended for BTS with regard to OS and DFS(P<0.05).dNLR was related to stoma construction(P=0.001),pneumonia(P=0.054),and DFS(P=0.009)in ES.LMR was closely related to lymph node invasion(LVI)(P=0.009),OS(P=0.020),and DFS(P=0.046)in the BTS group.dNLR was an independent risk factor for ES in both OS(P=0.032)and DFS(P=0.016).LMR affected OS(P=0.053)and DFS(P=0.052)in the BTS group.LMR could differentiate the OS between the ES and BTS groups(P<0.05).CONCLUSION Preoperative dNLR and LMR could predict OS and DFS in patients undergoing ES and BTS,respectively.For O
