Preparation of Aerogel-like Silica Foam with the Hollow-Sphere-Based 3D Network Skeleton by the Cast-in Situ Method and Ambient Pressure Drying.

Silica aerogels have incomparable advantages among thermal insulation materials because of their ultralow density and thermal conductivity, but cumbersome production processes, high cost, and low mechanical stability limit their practical application. In this study, a novel aqueous process to prepare lightweight aerogel-like silica foams (ASFoams) through the cast-in situ method and ambient pressure drying was proposed with multiblock polyurethane surfactant as the vesicle template. ASFoams possess a unique loose stacking morphology of the silica hollow sphere with a 3D network structure as the skeleton, which endues ASFoams with a low density of 0.

Chemotherapy with a TP Regimen in Combination with Stereotactic Radiotherapy Could Significantly Optimize the Clinical Efficacy of NSCLC Treatment.

The changes in lifestyle and bad living habits have a significant impact on the health of people, resulting in an increasing prevalence of lung cancer. The most prevalent kind of lung cancer is nonsmall cell lung cancer (NSCLC), which accounts for around 80% of all cases. Chemotherapy is a common treatment method in clinical practice with certain negative effects.

Centromere protein N promotes lung adenocarcinoma progression by activating PI3K/AKT signaling pathway.

Background: As an important member of centromere family, centromere associated protein N (CENPN) was abnormally expressed in varied malignant tumors.

Objective: This paper aimed to analyze the expression and related mechanism of CENPN in lung adenocarcinoma (LUAD).

Methods: The expression of CENPN in LUAD was analyzed by Gene Expression Profiling Interactive Analysis (GEPIA) database.

Application of Apriori Improvement Algorithm in Asthma Case Data Mining.

In Chinese medicine, asthma cases contain a large amount of empirical data which are obtained from the clinical diagnosis of doctors throughout the year. Data correlation analysis method is among the common mechanisms which are used to mine association between the (1) prescriptions and prescribers (doctors in this case) and (2) symptoms and medications for a particular disease in the hospitals. In this paper, initially, a thorough analysis of expected performance and shortcomings of the Apriori algorithm in mining of medical case data is presented.

Implementing sequencing-based surveillance in developing countries: findings from a pilot rollout for hepatitis A in China.

Background: The emergence of SARS-Cov2 variants has highlighted the need to implement sequencing-based surveillance in developing countries for early response to mutant viruses of concern. However, limited information on how to implement sequencing-based surveillance is available, and the feasibility and performance of this new type of surveillance are still in question.

Methods: To understand the challenges with the implementation and to promote sequencing-based surveillance, we reported findings from a pilot for hepatitis A (HepA) in five sentinel provinces in China as an example of sequencing-based surveillance implementation.

Acupuncture for acute low back pain: a systematic review and meta-analysis.

Background: Acupuncture has been widely used for acute low back pain (LBP), yet there remains continued controversy regarding its efficacy. Therefore, we aimed to critically evaluate the evidence for acupuncture as an effective treatment for acute LBP.

Methods: English and Chinese databases were searched for randomized controlled trials (RCTs) that involved acupuncture for acute LBP published up to May 2020.

Formate-Selective CO Electrochemical Reduction with a Hydrogen-Reduction-Suppressing Bronze Alloy Hollow-Fiber Electrode.

Electroreduction carbon dioxide into formate has been regarded as a hopeful measure to relieve global warming. Copper-based hollow fibers demonstrated good performances on converting carbon dioxide in previous researches. Herein Cu-Sn alloy hollow fibers were synthesized in an innovative way, combining the structure advantages of hollow fiber and high selectivity towards formate on η' bronze.

Experience of N-acetylcysteine airway management in the successful treatment of one case of critical condition with COVID-19: A case report.

Rationale: The new coronavirus pneumonia Corona Virus Disease 2019 (COVID-19) has become a global pandemic. Patients with critically COVID-19 usually require invasive respiratory support, and the airway management is particularly important and the prognosis is poor.

Patient Concerns: A 64-year-old man with an anastomotic fistula after radical treatment of esophageal cancer and right-side encapsulated pyopneumothorax was admitted with cough and dyspnea.

Construction of Ti-TiO-CNpor compound coupling photocatalysis and Fenton-like process: Self-driven Fenton-like process without extra HO addition.

An efficient heterogeneous photocatalytic process coupling photocatalysis and Fenton-like process was carried out, where the Fenton-like cycle could be driven by self-produced HO rather than extra HO addition. It was revealed that CNpor exhibited good performance at HO production in pure water, which was enhanced up to eight times than bare g-CN. Fenton-like cycle was constructed in Ti-TiO-CNpor as CNpor severed as HO donator, while the Ti-TiO was able to provide photoinduced electrons for the Fenton-like process, resulting in the generation of much more OH radical.

Ionic liquid-based vortex-assisted dispersive liquid-liquid microextraction of organophosphorus pesticides in apple and pear.

An ionic liquid-based vortex-assisted dispersive liquid-liquid microextraction (DLLME) was developed for the analysis of trace amounts of six organophosphorus pesticides (OPPs) in apple and pear coupled with high-performance liquid chromatography. During the DLLME, the effect of some experimental factors including extraction solvent and its volume, dispersion solvent and its volume, vortex time, salt addition, and pH on the extraction procedure were investigated. Under the chosen extraction conditions, the analytes were enriched more than 300-fold and the limits of detections were greatly dropped to 0.

[Simple screening table for primary osteoporosis in senior people].

Objective: To develop a simple screening table for primary osteoporosis (POP) in senior men and women.

Methods: Questionnaires were designed to obtain the risk factors associated with osteoporosis and bone mineral density (BMD), which were measured in 146 community residents over 60. The multiple stepwise regression was used to find out the risk factors and establish the screening index.
