Metal-organic frameworks （MOFs) materials have gained a lot of attention because of their good stability, excellent adsorption properties and designability. In the last decade, the research about MOFs materials has developed rapidly. As an important research tool, theoretical computation and simulation have played an irreplaceable role in the study of adsorption mechanism and high-throughput screening of MOFs materials and other work studies. This work summarizes the computation and simulation methods including quantum mechanical calculations, molecular mechanics simulation, mesoscopic simulation, finite element simulation and machine learning, summarizes the different levels of computation and simulation methods used to solve the main scientific problems in the research of MOFs materials, and highlights the progress of the application of these methods in several typical research areas, such as the adsorption separation and storage of gases, adsorption separation and extraction of organic compounds in solution, catalytic reaction and drug loading. Finally, the prospect and development of computation and simulation for the study of MOFs materials are proposed. [ABSTRACT FROM AUTHOR]

Objective To investigate the relationships between serum periostin (POSTN), signal transductor and transcriptional activator 3 (STAT3) levels and disease severity and prognosis in patients with chronic heart failure (CHF) in dilated cardiomyopathy (DCM). Methods Totally 142 patients with DCM CHF (the DCM CHF group) and 50 healthy physical examination volunteers (the control group) were selected. According to the New York Heart Association (NYHA) cardiac function classification, the patients with DCM CHF were divided into the Class I group of 16 cases, Class II group of 27 cases, Class III group of 53 cases and Class IV group of 46 cases. The patients with DCM CHF were followed up for 1 year, and were divided into the poor prognosis group (53 cases) and good prognosis group (89 cases) according to the prognosis. Enzyme-linked immunosorbent assay was used to detect serum POSTN and STAT3 in the two groups. Spearman correlation method was used to analyze the correlation between serum POSTN and STAT3 levels and NYHA cardiac function classification in patients with DCM CHF. Multifactorial Logistic regression was used to analyze the influencing factors of poor prognosis in patients with DCM CHF. Receiver operating characteristic (ROC) curve was used to analyze the predictive value of serum POSTN and STAT3 levels on poor prognosis of DCM CHF patients. Results Serum POSTN and STAT3 levels were higher in the DCM CHF group than in the control group (both P<0. 05). Serum POSTN and STAT3 levels increased sequentially in the Class I, Class II, Class III, and Class IV groups (all P<0. 05). Spearman's correlation method analysis showed that serum POSTN and STAT3 levels were positively correlated with NYHA cardiac function class in patients with DCM CHF (rs =0. 814 and 0. 808, respectively; all P<0. 05). Multifactorial Logistic regression analysis showed that the older age, NYHA cardiac function class ≥ III, high N-terminal pro-B-type natriuretic peptide level, high POSTN level, and high STAT3 level were independent risk factors for poor prognosis of DCM CHF patients, and high left ventricular ejection fraction (LVEF) was an independent protective factor (all P<0. 05). ROC curve analysis showed that the area under the curve of serum POSTN combined with STAT3 in predicting poor prognosis of patients with DCM CHF was greater than that of either alone (both P<0. 05). Conclusion Serum POSTN and STAT3 levels are elevated in patients with DCM CHF, and changes in the levels of both can reflect the severity of the disease, and serum POSTN combined with STAT3 has high predictive efficacy for poor prognosis in DCM CHF patients.

This paper introduces a research-based comprehensive experiment involving the synthesis of quinoline derivatives and investigations on the effect of their structures on the colorimetric sensing performance of anions. During this experiment, students will learn and master the synthesis and characterization methods used for quinoline heterocyclic compounds and their derivatives. Based on the principle of organic small molecule sensing and recognition, students will learn to use ultraviolet-visible absorption spectroscopy instrumentation and study the anion sensing and recognition performance of quinoline compounds (P1, P2, and P3) as probes. Using the spectral data processed by Origin and visualized colorimetric images, students can better intuitively understand the anion sensing and recognition performance of different probes, along with the significance of the probe molecular structure in regulating sensing performance.

Objective: Atrial fibrillation is one of the most common arrhythmias. The mechanism of atrial fibrillation is not yet clear. A number of previous studies have shown that adipokines, including leptin, visfatin, are closely related to cardiovascular diseases.In this study, the relationship between leptin, visfatin and atrial fibrillation was investigated. Methods: In this study, the secretion levels of leptin and visfatin in peripheral blood and epicardial adipose tissue of AF group and control group were detected. To explore the relationship between leptin, visfatin and AF. Results: The average concentration of visfatin in peripheral blood serum of atrial fibrillation group was 15.95±10.44 ng/mL, and the sinus rhythm group was 20.28±12.90 ng/mL, and there was not statistically significant (P=0.169); The average concentration of leptin in peripheral blood in the atrial fibrillation group was 1.48 ng/mL, and in the sinus rhythm group was 2.56ng/mL. The comparison between the two was statistically significant (P=0.0027). Serum leptin levels in the sinus group were significantly higher than those in the atrial fibrillation group; In epicardial adipose tissue, the expression of leptin in the atrial fibrillation group was significantly lower than that in the control group (P=0.032), while the expression of visfatin was not statistically different between the two groups (P=0.06). Conclusions: The incidence of atrial fibrillation can be reduced by high levels of leptin in peripheral blood serum and epicardial adipose tissue. The levels of visfatin in peripheral blood serum and epicardial adipose tissue in patients with atrial fibrillation was not significantly different from those with sinus rhythm. Therefore there may not be a correlation between visfatin and atrial fibrillation. [ABSTRACT FROM AUTHOR]

The incidence of colorectal cancer (CRC) in China ranks second among all cancer types, and the mortality rate ranks fourth among all cancer types. Contemporaneous peritoneal metastasis (PM) occurs in 5% to 15% of CRC patients, and heterochronous PM occurs in about 20% of CRC patients. CRC PM is the third common metastatic site after liver and lung metastasis. Although better progress has been made in chemotherapy to improve the prognosis of patients with CRC PM,the survival benefit of patients with CRC PM is still less. Currently, cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy is mainly used in clinic, and the prognosis is better but will still relapse. The current mechanism of CRC PM is mainly the alteration of the biology of the tumor cells themselves and the alteration of the tumor microenvironment. As the mechanism of CRC PM has been intensively studied, the potential pathways for CRC PM treatment have also become more diverse. This article briefly described the clinic treatment of common CRC PM and provided a review of potential treatments for CRC PM,from the perspective of CRC PM mechanism [ABSTRACT FROM AUTHOR]

The effects of low degree inulin LPI（DP≤10）,medium degree inulin MPI（DP 2-60） and high degree inulin HPI（DP≥23） on the powder properties, granular strength and cooking quality of tapioca pearls were studied. The results showed that inulin could interact with starch in hydrogen bond, compete with starch for water, inhibit the swelling of starch particles and improve the water solubility of the powder, thus affecting the granular strength and cooking quality of tapioca pearls. LPI has the stronger hydrogen bond interaction with starch and forms a stronger gel network structure, so it is best to add LPI. Adding 3%（w/w） LPI significantly reduced friction loss（1. 96%-1. 04%） and cooking loss（47. 8%-43. 6%） of tapioca pearls. It also significantly improved the transparency（9. 4%-12. 6%）,volume expansion（4. 9-7. 0）,hardness（483 to 674 g）,and chewiness（202 to 299 g）. The addition of MPI and HPI had adverse effects on the transparency, breaking force or cooking loss of tapioca pearls. This study shows that the addition of inulin is an effective green means to improve the quality of tapioca pearls, and the addition of low polymerization inulin is better. [ABSTRACT FROM AUTHOR]
