Background: Chronic obstructive pulmonary disease (COPD) is a serious chronic condition with a global impact. Symptoms of COPD include progressive dyspnea, breathlessness, cough, and sputum production, which have a considerable impact on the lives of patients. In addition to the human cost of living with COPD and the resulting death, COPD entails a huge economic burden on the Chinese population, with patients spending up to one-third of the average family income on COPD management in some regions is clinically beneficial to adopt preventable measures via prudent COPD care utilization, monetary costs, and hospitalizations. Methods: Toward this end, this study compared the relative effectiveness of six indices in predicting patient healthcare utilization, cost of care, and patient health outcome. The six assessment systems evaluated included the three multidimensional Body mass index, Obstruction, Dyspnea, Exercise capacity index, Dyspnea, Obstruction, Smoking, Exacerbation (DOSE) index, and COPD Assessment Test index, or the unidimensional measures that best predict the future of patient healthcare utilization, cost of care, and patient health outcome among Chinese COPD patients. Results: Multiple linear regression models were created for each healthcare utilization, cost, and outcome including a single COPD index and the same group of demographic variables for each of the outcomes. Conclusion: We conclude that the DOSE index facilitates the prediction of patient healthcare utilization, disease expenditure, and negative clinical outcomes. Our study indicates that the DOSE index has a potential role beyond clinical predictions.

Artificial extracellular matrices play important roles in the regulation of stem cell behavior. To generate materials for tissue engineering, active functional groups, such as amino, carboxyl, and hydroxyl, are often introduced to change the properties of the biomaterial surface. In this study, we chemically modified coverslips to create sur-faces with different amino densities and investigated the adhesion, migration, and differentiation of neural stem cells (NSCs) under serum-free culture conditions. We observed that a higher amino density significantly promoted NSCs attach-ment, enhanced neuronal differentiation and promoted excitatory synapse formation in vitro. These results indicate that the amino density significantly affected the biological behavior of NSCs. Thus, the density and impact of functional groups in extracellular matrices should be considered in the research and development of materials for tissue engineering.

Purpose: The selection of open prostatectomy (OP) over transurethral laser surgery is controversial for large volume prostates. Thus, we aim to compare the efficacy and safety of transurethral laser versus OP, and provide the latest evidence of clinical practice for large-sized benign prostatic hyperplasia (BPH). Materials and Methods: This meta-analysis used Review Manager V5.3 software and the systematic literature search of Cochrane Library, Embase, PubMed, and Web of Science datasets was performed for citations published from 2000 to 2020 that compared transurethral laser with OP for the treatment of large BPH. Variables of interest assessing the two techniques included clinical characteristics, and the perioperation-, effectiveness-, and complication-related outcomes. Results: The meta-analysis included twelve studies containing 1,514 patients, with 792 laser and 722 OP. The transurethral laser group was associated with shorter hospital stay and catheterization duration, and less hemoglobin decreased in the perioperative variables. There was no significant difference in the international prostate symptom score, post-void residual urine volume, maximum flow rate, and quality of life score. Transurethral laser group had a significantly lower incidence of blood transfusion than OP group (odds ratio, 0.10; 95% confidence interval, 0.05 to 0.19; p<0.001; I2=8%), and no statistical differences were found with respect to the other complications. Conclusions: Both OP and transurethral laser prostatectomy are effective and safe treatments for large prostate adenomas. With these advantages of less blood loss and transfusion, and shorter catheterization time and hospital stay, laser may be a better choice for large BPH.

1-Deoxynojirimycin (DNJ) as a kind of alkaloid has been confirmed that could modulate glycometabolism andhas toxicity for the eri-silkworm in our previous research. On the contrary, what is the potentially defensivemechanism when the DNJ enters the eri-silkworm. Based on comparative transcriptome sequencing, we foundthat ATP-binding cassette (ABC) transporter genes could be induced significantly by DNJ. In this study, a total of16 putative ABC transporter genes were identified, which can be classified into seven subfamilies, namely oneABCA, four ABCBs, three ABCCs, two ABCDs, one ABCE, three ABCFs, and two ABCGs. Phylogenetic analysisrevealed that ScABCs had strong conservation with Bombyx mori. Reverse transcription quantitative PCR (RTqPCR)suggested that 6 ABC transporters had a strong positive correlation between RT-qPCR and transcriptomedata. Additionally, S. c. ricini ABC transporter C-subfamily 4 (ScABCC4), S. c. ricini ABC transporter G-subfamily4 (ScABCG4), S. c. ricini ABC transporter A-subfamily 3 (ScABCA3) and S. c. ricini ABC transporter C-subfamily10 (ScABCC10) showed different expression pattern in two feed dose (1% and 2% DNJ) and three time points(6h, 12 h, 48 h). This study provides the first study on identification, characterization and expression patterns ofABC transporter genes in S. c. ricini response to DNJ, and lays a foundation for further understanding of theirphysiological roles response to the alkaloid.

Lysyl oxidase-like 2 (LOXL2), a member of the lysyl oxidase (LOX) family, is a copper-dependent enzyme that catalyzes oxidative deamination of lysine residues on protein substrates. LOXL2 was found to be overexpressed in esophageal squamous cell carcinoma (ESCC) in our previous research. We later identified a LOXL2 splicing variant LOXL2-delta72 and we overexpressed LOXL2-delta72 and its wild type counterpart in ESCC cells following microarray analyses. First, the differentially expressed genes (DEGs) of LOXL2 and LOXL2-delta72 compared to empty plasmid were applied to generate protein-protein interaction (PPI) sub-networks. Comparison of these two sub-networks showed hundreds of different proteins. To reveal the potential specific roles of LOXL2- delta72 compared to its wild type, the DEGs of LOXL2-delta72 vs LOXL2 were also applied to construct a PPI sub-network which was annotated by Gene Ontology. The functional annotation map indicated the third PPI sub-network involved hundreds of GO terms, such as "cell cycle arrest", "G1/S transition of mitotic cell cycle", "interphase", "cell-matrix adhesion" and "cell-substrate adhesion", as well as significant "immunity" related terms, such as "innate immune response", "regulation of defense response" and "Toll signaling pathway". These results provide important clues for experimental identification of the specific biological roles and molecular mechanisms of LOXL2-delta72. This study also provided a work flow to test the different roles of a splicing variant with high-throughput data.

Medical product contamination is a serious threat to patients’ health. However, designing medical covers thatensure Janus performance and outstanding abrasion resistance, mechanical performances has remained a great challenge. Inthis study, a novel Janus nonwoven fabric nonwoven fabric consists of a hydrophilic inner layer of polylactic acid (PLA)/lowmeltingpolylactic acid (LPLA) and a coated outer layer of hydrophobic thermoplastic polyurethane (TPU) is successfullyfabricated. The subsequent PLA/LPLA-TPU textiles exhibits excellent protective performance of inner absorption. Moreover, the coating improves tensile strength and increases abrasion resistance. A mechanism of mechanical failure isfurther studied. This kind of nonwoven fabric is suggested to be a promising candidate for medical covers and health supplies.

As a strong and low-priced austenite stabilizer, nitrogen (0.085 wt%) was deliberately added into a hot-rolled Fe-0.2C-5Mn TRIP steel for optimizing the strength–ductility balance. Nitrogen addition can not only increase austenite fraction (> 50%), but also favor the improvement of austenite stability due to its partition behavior from ferrite to austenite during intercritical annealing. Besides, the low annealing temperature (635 °C) and nitrogen addition result in the simultaneous precipitation of cementite (size, 21–396 nm) and carbonitride (size, 7–193 nm) in ferrite and at grain boundaries, which can effectively increase the yield strength through precipitation strengthening (33–63 and 41–61 MPa, respectively). Furthermore, the sufficient interstitial solute originated from N addition as well as the discontinuous TRIP effect benefits the strong serrated flow behavior and multi-peak strain hardening behavior. As a result, the strong TRIP effect together with precipitation strengthening is believed to be responsible for the excellent strength–ductility balance of present steel annealed for 3 h, demonstrating a high tensile strength of 1043 MPa, outstanding total elongation of 43.3% and superior product of strength and elongation (PSE) of 44.8 GPa%.
