Study on the efficacy of early treatment with pirfenidone on the lung function of patients with idiopathic pulmonary fibrosis.

Background: Idiopathic pulmonary fibrosis (IPF) is classified under fibrotic interstitial pneumonia, characterized by a chronic and progressive course. The predominant clinical features of IPF include dyspnea and pulmonary dysfunction.

Aim: To assess the effects of pirfenidone in the early treatment of IPF on lung function in patients.

UBE2V2 Positively Correlates With PD-L1 Expression and Confers Poor Patient Survival in Lung Adenocarcinoma.

This research aims to explore the diagnostic and prognostic value of ubiquitin-conjugating enzyme E2 variant 2 (UBE2V2) in lung adenocarcinoma (LUAD). The expression of UBE2V2 in clinical specimens was evaluated by bioinformatics analyses and immunohistochemistry. Bioinformatics analyses relying on the The Cancer Genome Atlas (TCGA) database suggested the elevated UBE2V2 mRNA levels in LUAD in comparison to adjacent normal tissues.

Pancreas lipiodol embolism induced acute necrotizing pancreatitis following transcatheter arterial chemoembolization for hepatocellular carcinoma: A case report and literature review.

Rationale: Transcatheter arterial chemoembolization (TACE) is recognized as one of the most commonly used modalities for non-surgical treatment for advanced hepatocellular carcinoma (HCC). Ectopic lipiodol embolism is an extremely rare complication of TACE.

Patient Concerns: A 61-year-old man who had a 10-year history of cirrhosis caused by hepatitis B infection was diagnosed with ascites and HCC.

Rare spontaneous intrahepatic portosystemic shunt in hepatitis B-induced cirrhosis: A case report.

Background: The portosystemic shunt is the pathway between the portal vein (PV) and systemic circulation. A spontaneous intrahepatic portosystemic shunt (SPISS) is a rare portosystemic shunt type. Here we report an extremely rare type of SPISS, a spontaneous intrahepatic PV-inferior vena cava shunt (SPIVCS).

Ductopenia and cirrhosis in a 32-year-old woman with progressive familial intrahepatic cholestasis type 3: A case report and review of the literature.

Progressive familial intrahepatic cholestasis type 3 is caused by a mutation in the ATP-binding cassette, subfamily B, member 4 () gene encoding multidrug resistance protein 3. A 32-year-old woman with a history of acute hepatitis at age 9 years was found to have jaundice during pregnancy in 2008, and was diagnosed as having intrahepatic cholestasis of pregnancy. In 2009, she underwent cholecystectomy for gallstones and chronic cholecystitis.

Control on Dimensions and Supramolecular Chirality of Self-Assemblies through Light and Metal Ions.

Precise control over helical chirality and dimensions of molecular self-assemblies, a remaining challenge for both chemists and materials scientists, is the key to manipulate the property and performance of supramolecular materials. Herein, we report that a cholesterol-azopyridine conjugate could self-assemble into organogels with photocontrollable dimensional transition from 2D microbelts to 1D nanotubes and finally to 0D nanoparticles. The E/ Z-Photoisomerization of the 4-azopyridine unit is the major driving force for the dimensional transformation.

Controlling Supramolecular Chirality of Two-Component Hydrogels by J- and H-Aggregation of Building Blocks.

While manipulating the helicity of nanostructures is a challenging task, it attracts great research interest on account of its crucial role in better understanding the formation mechanisms of helical systems. For the supramolecular chirality in self-assembly systems, one challenge is how to understand the origin of supramolecular chirality and inherent helicity information on nanostructures regulated by functionality-oriented stacking modes (such as J- and H-aggregation) of building blocks. Herein, two-component hydrogels were prepared by phenylalanine-based enantiomers and achiral bis(pyridinyl) derivatives, where helical nanofibers with inverse handedness as well as controllable helical pitch and diameter were readily obtained through stoichiometric coassembly of these building blocks.

Helicity Inversion of Supramolecular Hydrogels Induced by Achiral Substituents.

Probing the supramolecular chirality of assemblies and controlling their handedness are closely related to the origin of chirality at the supramolecular level and the development of smart materials with desired handedness. However, it remains unclear how achiral residues covalently bonded to chiral amino acids can function in the chirality inversion of supramolecular assemblies. Herein, we report macroscopic chirality and dynamic manipulation of chiroptical activity of hydrogels self-assembled from phenylalanine derivatives, together with the inversion of their handedness achieved solely by exchanging achiral substituents between oligo(ethylene glycol) and carboxylic acid groups.

Activation of Bcl-2-Caspase-9 Apoptosis Pathway in the Testis of Asthmatic Mice.

Background: Apoptosis plays a critical role in controlling the proliferation and differentiation of germ cells during spermatogenesis. Dysregulation of the fine-tuned balance may lead to the onset of testicular diseases. In this study, we investigated the activation status of apoptosis pathways in the testicular tissues under the background of an asthmatic mouse model.

The development of a clinical score for the prediction of nonalcoholic steatohepatitis in patients with nonalcoholic fatty liver disease using routine parameters.

Background/aims: To develop a clinical score for the prediction of nonalcoholic steatohepatitis (NASH) using routine parameters in patients with nonalcoholic fatty liver disease who had abnormal liver function tests and/or fatty liver detected by ultrasonography.

Materials And Methods: To identify parameters associated with the presence of NASH by evaluating anthropometric characteristics and routine biomarkers of 82 patients with histologically proven NAFLD and to develop a clinical score for predicting NASH according to the area under the curve of receiver operating characteristics (AUC) of parameters.

Results: Four parameters [alanine aminotransferase (ALT), gamma-glutamyl transferase (GGT), C-reactive protein (CRP), and apolipoprotein B (ApoB)/apolipoprotein A1 (ApoA1) ratio] were significantly linked to NASH.

Frequent mutations in EGFR, KRAS and TP53 genes in human lung cancer tumors detected by ion torrent DNA sequencing.

Lung cancer is the most common malignancy and the leading cause of cancer deaths worldwide. While smoking is by far the leading cause of lung cancer, other environmental and genetic factors influence the development and progression of the cancer. Since unique mutations patterns have been observed in individual cancer samples, identification and characterization of the distinctive lung cancer molecular profile is essential for developing more effective, tailored therapies.
