Predicting mechanism of immune response in microsatellite instability colorectal cancer.

Colorectal cancer (CRC), also known as colon cancer, is the third most common cancer and the fourth most cause of cancer-related death in the world. CRC can be classified into two major subtypes, including microsatellite instability (MSI) and microsatellite stability (MSS), which showed different characteristics in immunotherapy. Low sensitivity of diagnostic biomarkers and metastasis are still the principal cause of mortality, especially in MSI.

LINC00858 facilitates formation of hepatic metastases from colorectal cancer via regulating the miR-132-3p/IGF2BP1 axis.

Hepatic metastasis is a major cause of colorectal cancer (CRC)-related deaths. Presently, the role of long non-coding RNAs (lncRNAs) in hepatic metastases from CRC is elusive. We dissected possible interplay between LINC00858/miR-132-3p/IGF2BP1 via bioinformatics approaches.

Prognostic Factors in Stage IV Colorectal Cancer Patients With Resection of Liver and/or Pulmonary Metastases: A Population-Based Cohort Study.

Importance: Currently, surgical resection of distant metastatic lesions has become the preferred treatment for select colorectal cancer (CRC) patients with liver metastasis (LM) and/or pulmonary metastasis (PM). Metastasectomy is the most common curative method. However, evidence of the factors affecting the prognosis of CRC patients after resection of LM and/or PM is still insufficient.

Mini Percutaneous Nephrolithotomy Is a Noninferior Modality to Standard Percutaneous Nephrolithotomy for the Management of 20-40mm Renal Calculi: A Multicenter Randomized Controlled Trial.

Background: High quality of evidence comparing mini percutaneous nephrolithotomy (mPNL) with standard percutaneous nephrolithotomy (sPNL) for the treatment of larger-sized renal stones is lacking.

Objective: To compare the efficacy and safety of mPNL and sPNL for the treatment of 20-40mm renal stones.

Design, Setting, And Participants: A parallel, open-label, and noninferior randomized controlled trial was performed at 20 Chinese centers (2016-2019).

Plasma-Liquid Interface Manipulated by Chamber Structure: An Experimental and Theoretical Approach.

To respond to global challenges of environmental contaminations, pursue more advanced material technologies, and achieve novel biomedical therapies, a variety of plasmas have been applied to wastewater and food processing, biomaterial treatments, and plasma-liquid ignitions. As these applications highly depend on the plasma-liquid interactions, researchers are now focusing on the physical and chemical reactions on the plasma-liquid interface. With massive publications reporting the molecular transfers, chemical pathways, and their effects on plasma treatments, this work provides a new point of view that the plasma-liquid interface can be manipulated by the chamber structure.

Integrated analysis of quantitative proteome and transcriptional profiles reveals abnormal gene expression and signal pathway in bladder cancer.

Background: Bladder cancer (BCa) is a tumor associated with high morbidity and mortality and its incidence is increasing worldwide. However, the pathogenesis of bladder cancer is not well understood.

Objective: To further illustrate the molecular mechanisms involved in the pathogenesis of BCa and identify potential therapeutic targets, we combined the transcriptomic analysis with RNA sequencing and tandem mass tags (TMT)-based proteomic methods to quantitatively screen the differentially expressed genes and proteins between bladder cancer tissues (BC) and adjacent normal tissues (AN).

The status and characteristics of urinary stone composition in China.

Objectives: To explore characteristics of urinary stone composition in China, and determine the effects of gender, age, body mass index (BMI), stone location, and geographical region on stone composition.

Patients And Methods: We prospectively used Fourier-transform infrared spectroscopy to analyse stones from consecutive patients presenting with new-onset urolithiasis at 46 hospitals in seven geographical areas of China, between 1 June 2010 and 31 May 2015. Chi-squared tests and logistic regression analyses were used to determine associations between stone composition and gender, age, BMI, stone location, and geographical region.

Design and discovery of a novel half-Heusler transparent hole conductor made of all-metallic heavy elements.

Transparent conductors combine two generally contradictory physical properties, but there are numerous applications where both functionalities are crucial. Previous searches focused on doping wide-gap metal oxides. Focusing instead on the family of 18 valence electron ternary ABX compounds that consist of elements A, B and X in 1:1:1 stoichiometry, we search theoretically for electronic structures that simultaneously lead to optical transparency while accommodating intrinsic defect structures that produce uncompensated free holes.

Stereotactic localisation system: a modified puncture technique for percutaneous nephrolithotomy.

The objective of the study was to establish and evaluate a modified puncture and dilation technique-"stereotaxic localisation" system-and the corresponding instruments for percutaneous nephrostomy. Four hundred patients were randomised to the intervention group (200 cases, stereotaxic location puncture and dilation procedures) and the traditional group (200 cases, traditional procedure) under X-ray guidance. In the modified intervention system, the distance and horizontal angle of the puncture pathway between the puncture point and the target site were calculated accurately.

First-principles study on thermodynamic properties and phase transitions in TiS(2).

Structural and vibrational properties of TiS(2) with the CdI(2) structure have been studied to high pressures from density functional calculations with the local density approximation (LDA). The calculated axial compressibility of the CdI(2)-type phase agrees well with experimental data and is typical of layered transition-metal dichalcogenides. The obtained phonon dispersions show a good correspondence with available experiments.

Prediction of high-pressure polymorphism in NiS2 at megabar pressures.

A sequence of pressure-induced phase transitions of vaesite, NiS(2), with pyrite structure, has been established from static LDA calculations. A dozen AX(2) candidate structures have been studied at high pressures including cotunnite (α-PbCl(2)), which is commonly observed in other AX(2) compounds at high pressures. At 150 GPa, vaesite transforms to a tetragonal phase (P4(2)/n) rather than cotunnite.

[Indwelling the anterior urethral stent: a good treatment option for anterior urethral stricture].

Objective: To observe the clinical effect of indwelling the anterior urethral stent in the treatment of anterior urethral stricture.

Methods: We included 38 patients with anterior urethral stricture in the treatment group, and another 38 in the control, the former treated by indwelling the anterior urethral stent, and the latter by urethral dilatation. Then we analyzed the clinical results by comparing the Qmax, urinary hesitancy and numbers of urethral dilations between the two groups.
