ABSTRACT
Objective: To observe the characteristics and trends during the last 11 years of risk factors of young adults with first acute coronary syndrome (ACS). Methods: It was a cross-sectional study. We included young adults (18 to 44 years old) hospitalized for acute coronary syndrome in Beijing Anzhen Hospital for a first time from January 2007 to December 2017. Acute coronary syndromes include ST-elevation myocardial infarction (STEMI), non-ST-elevation myocardial infarction (NSTEMI), and unstable angina (UA). The general information, medical history and laboratory test were recorded. Risk factors of ACS were smoking, dyslipidemia, overweight/obesity, hypertension and diabetes. Results: Data from 7 106 patients were analyzed, mean age was (39.8±4.2) years old and 6 593(92.8%)were men, including 2 254 (31.7%) STEMI, 704 (9.9%) NSTEMI and 4 148 (58.4%) UA. Most patients were male (6 593(92.8%)). Dyslipidemia (85.8%(6 094/7 106)), overweight/obesity (82.3%(5 850/7 106)), and smoking (63.9%(4 545/7 106)) were most prevalent. 98.3% (6 885/7 106) patients had at least 1 risk factor. The prevalence of hypertension, diabetes and overweight/obesity increased from 2007 to 2017. Rates of hypertension increased from 37.1%(111/299) to 48.1%(498/1 035) (Ptrend<0.01), diabetes from 12.0%(36/299) to 19.4%(201/1 035) (Ptrend<0.01), overweight/obesity from 74.2%(222/299) to 83.9%(868/1 035) (Ptrend<0.05), respectively. Conclusions: Dyslipidemia, overweight/obesity and smoking are most prevalent risk factors in young adults with a first ACS and most patients have at least 1 risk factor for ACS. Rates of hypertension, diabetes and overweight/obesity progressively increases over time in this patient cohort.
ABSTRACT
In addition to primary diseases, critically ill patients often suffered from multiple functional disorders, including pulmonary dysfunction. Pulmonary rehabilitation can effectively improve the lung and overall function of patients, which need assistance of relevant examinations. Point-of-care ultrasound (POCUS) can not only help to diagnose, evaluate, monitor and treat the disease faster, more accurate and safer, but also reduce the adverse events resulting from handling, activities and radiation, which is applied more extensively in critical patients accepting pulmonary rehabilitation.

Diffuse large B-cell lymphoma (DLBCL) accounts for approximately 30% of the non-Hodgkin's lymphoma patients. The underlying molecular mechanism of its pathogenesis is not well defined and the survival rate of DLBCL patients is very low. Moreover, the annual incidence and mortality of DLBCL is still rising. Accordingly, identification and characterization of new molecular pathways of DLBCL will lead to the development of novel diagnostic markers and molecular therapeutic targets. Long non-coding RNAs (LncRNA) are non-coding RNAs with a length greater than 200 bp in eukaryotic cells, which can regulate the expression of their target genes at the transcriptional and post transcriptional levels. The function of LncRNAs is involved in the initiation, progression, invasion and metastasis of many cancers. Recently, the role of LncRNAs in DLBCL has been identified and intensely studied. This review summarizes the recent discoveries in the expression and function of LncRNAs including HULC,PEG10,LincRNA-p21,HOTAIR,LUNAR1,MALAT1 and SubSigLnc-17 in DLBCL, so as to find potential diagnostic biomarkers and therapeutic targets for DLBCL.

ABSTRACT
BACKGROUND:The traditional method of preparing tissue-engineered conduit has the defects of complex shape manufacturing and uncontrolable inner space structure, which cannot meet the requirements of some micro-catheters. OBJECTIVE:To prepare a bionic spinal catheter and analyze its performance. METHODS:The data model of the conduit was established using Solid Works software, and platform scan path was generated onthree-dimensionalprinter to produce the bionic spinal catheter with fibroin and colagen as raw materials. Then the water absorption, porosity, mechanical properties and celular compatibility of the conduits were detected. Next, the conduits were implanted into the subcutaneous tissue of rats and taken out at 1, 2, 3 and 4 weeks after surgery, respectively, to observe the degradation. RESULTS AND CONCLUSION:The porosity of the conduit was (53.6±1.0)%, the water absorption was (1347±19.4)%, and the compression modulus was (0.60±0.12) MPa. The micropores distributed uniformly with different size ranging from 10 to 240 μm. Spherical or fusiform stem cels survived in the pores and densely adhered to the conduit with pseudopodia. The degradation rate ofthe conduit was 20%, 59%, 74%and 100% at 1, 2, 3 and 4 weeks after surgery, respectively. These findings indicate that the artificial bionic spinal catheter has good biocompatibility and degradability.
ABSTRACT
BACKGROUND:Neural stem cel s with self-proliferation and differentiation potential are the ideal seed cel s for central nervous tissue engineering. Although col agen and silk fibroin as biological scaffold materials have been widely used, both of them used alone have certain shortcomings. Is it possible to combine the two materials to build a novel neural tissue-engineered scaffold? What is the effect of this novel scaffold on the growth and differentiation of neural stem cel s? OBJECTIVE:To observe the growth and differentiation of neural stem cel s seeded onto the novel composite scaffold. METHODS:The rat embryonic neural stem cells were inoculated onto new composite scaffolds, and then, their growth and differentiation were observed by light microscopy and scanning electron microscopy. Neural stem cells were cultured in conventional suspension culture as control group. Cell counting kit-8 assay was used to detect viability of neural stem cells in the two groups. Three-dimensional composite scaffolds carrying neural stem cells were slic ed into paraffin sections to observe the growth and differentiation of neural stem cells by hematoxylin-eosin staining and immunofluorescence staining. RESULTS AND CONCLUSION:Neural stem cel s cultured on the new composite scaffold grew and differentiated wel , and interconnected synapses were observed. Cel counting kit-8 assay showed that neural stem cel s on the scaffold grew wel , and the cel viability was significantly higher in the composite scaffold group than that in the control group (P<0.05). Hematoxylin-eosin staining and immunofluorescence staining of paraffin sections further provided evidence for good growth and differentiation of neural stem cel s on the scaffold. These results indicate that the novel composite scaffold with good biocompatibility benefits the growth and differentiation of neural stem cel s, promising a favorable application prospect.

ABSTRACT
BACKGROUND:Col agen and silk fibroin materials for construction of spinal cord scaffolds have been proven to repair or partial y repair damaged spinal cord nerve function. OBJECTIVE:To introduce partial characteristics of the col agen and silk fibroin and to review the recent progress and application as scaffolds in spinal cord tissue engineering. METHODS:A computer-based search of CNKI and PubMed databases (2003-01/2012-10) was performed for articles addressing the application of col agen and silk fibroin scaffolds in spinal cord injury with the keywords of“col agen, silk fibroin, scaffold, spinal cord injury”in Chinese and English, respectively. RESULTS AND CONCLUSION:Col agen has low antigenicity, good biocompatibility and biodegradability. Col agen and its degradation products can cause no inflammatory reactions in the body, but have the disadvantages of rapid degradation and poor mechanical properties. Silk fibroin has good biocompatibility and excellent mechanical properties, but its degradation is slow. The col agen and silk fibroin are compounded using an electrostatic spinning technology to improve the physical properties of the material on the basis of maintaining good biocompatibility. At present, fibroin or col agen materials in terms of nervous system repair have been studied, laying some foundation for spinal cord tissue engineering. Considering the similar characteristics and mechanics performance to the spinal cord tissue, col agen/silk fibroin composite materials are expected to become the ideal scaffold materials for spinal cord tissue engineering.
