The coronavirus disease 2019 (COVID-19) epidemic has been almost controlled in China under a series of policies, including "early diagnosis and early treatment". This study aimed to explore the association between treatment with Qingfei Paidu decoction (QFPDD) favorable clinical outcomes. In this retrospective multicenter study, we included 782 patients (males, 56 %; median age 46) confirmed COVID-19 from 54 hospitals nine provinces China, who were divided into four groups according...
Background: Novel coronavirus pneumonia (NCP) is often changing rapidly and fatal. Early detection early triage of disease 2019 (Covid-19) the key to success management disease. An easily obtainable yet accurate variable for both diagnosis prognosis urgently needed. We aim report predictive Value Neutrophil-to-Lymphocyte Ratio(NLR) worse clinical course COVID-19, which have not been well demonstrated. Methods: Our study consisted two stages, at first stage, a retrospective, single-center,...
Diamond, widely used in optoelectronic devices, plays a crucial role improving performance through studies of its electronic structure and response. This study combines computational methods experiments for analysis. Density functional theory calculates the diamond’s band refractive index, while Keldysh formula determines laser intensity at critical plasma density by evaluating laser-induced free electron density. By integrating coupled model with multi-physics field associative assignment,...
Background: Qingfei Paidu decoction (QFPDD) has been widely used in treating coronavirus disease 2019 (COVID-19) China. However, studies on the treatment effect of COVID-19 patients and other respiratory diseases have not well demonstrated. Our study aims to determine QFPDD combination with conventional diseases. Methods: This retrospective recruited who were treated for at least two courses (6 days) from seven hospitals five provinces January 21 March 18 2020. Demographic, epidemiological,...
Multi-spectral CT (MSCT) is increasingly used in industrial non-destructive testing and medical diagnosis because of its outstanding performance like material distinguishability. The process obtaining MSCT data can be modeled as nonlinear equations the basis decomposition comes down to inverse problem equations. For different spectra data, geometric inconsistent parameters cause geometrical rays, which will lead mismatched How solve accurately quickly a hot issue. This paper proposes general...
In engineering design, none of the existing models for calculating contact pressure in pin-loaded lug is fully compatible with actual working conditions. order to obtain a more accurate formula maximum lug, after verifying reliability finite element model PRESCALE measurement film, single-parameter and multi-parameter analysis two types factors affecting distribution compressive surface were conducted elastic state. The influence relevant design parameters on its was obtained, based Hertz...
Since the outbreak of COVID-19 in Wuhan, China December 2019, it has spread quickly and become a global pandemic. While epidemic been contained well due to unprecedented public health interventions, is still raging or not yet restrained some neighboring countries. Chinese government adopted strict policy immigration diversion major entry ports, makes Suifenhe port Heilongjiang Province undertook more importing population. It essential understand how imported cases other key factors screening...
Ultrafast laser direct writing inside materials has garnered significant attention for its applications in techniques like two-photon polymerization, stealth dicing and vertical slicing. 4H-Silicon Carbide (4H-SiC) slicing wide potentials from research to industry due low kerf loss high speed. In this paper, improve the processing quality lower separation strength, we introduce a multi-focal method with spherical aberrations caused by refractive index eliminated. Additionally, shaping...
Objective To compare the effects between small incision surgery and traditional on patients with thyroid tumor.Methods 96 tumor were randomly divided into two groups,the control group(n =48 cases) observation group (n cases).The received while surgery.Results The in groups had low complication rate,and no significant difference groups.Surgical scars,hospital time,operation time bleeding,of less than these of group(P <0.01).The satisfied cosmetic results.Followed up for five to thirty-seven...
Objective To explore the significance of detection acute-phase proteins in clinical diagnosis malignant diseases digestive system.Methods Fifty patients with system adopt enzyme linked immunosorbent assay (ELISA) method between 2010 February to 2011 were included (Study Group) and 50 cases healthy subjects same period (control group 1) benign 2) concentration serum acute phase proteins,including CRP,α1-AG α1-AT concentration.Results Through comparative analysis three groups study group,the...
Silicon carbide (SiC), the third-generation semiconductor material, is important in developing electronic power devices. Compared to wire sawing technology, Laser splitting SiC an efficient way produce wafers with reduced material loss. In this work, we propose a new method of continuous wave (CW) laser-assisted wafer based on modified layer by picosecond laser. For process CW laser irradiation layer, thermal-mechanical numerical simulations were performed calculate temperature and stress...
Background: Few studies have examined the association between treatment given time and clinical outcomes, which is indeed of great importance to management coronavirus disease 2019 (COVID-19). We performed this study explore whether early brings favorable outcomes. Methods: In retrospective multicenter study, we included patients aged 18 87 years with confirmed COVID-19 on admission from 54 hospitals in nine provinces China 21 January 10 March, 2020. Final date follow-up was March 17, All...
The growing interest in Laser Additive Manufacturing (LAM) High-entropy alloys (HEAs) during most recent years, the design of elements and scanning strategies are primary methods to overcome defects such as porosity, pores, segregation etc. Here we propose a new approach, novel real-time Shocking Melt Pool (LSMP), obtain melt pool modifications yield better HEAs. LSMP moves pulsed laser into liquid caused by continuous wave laser, enabling non-destructive fabrication high-performance...
