Burden of biliary tract carcinoma in China (1990-2021): Findings from the 2021 Global Burden of Disease Study.

Biliary tract carcinoma (BTC) is a group of malignant tumors that originate in the digestive system and occurs with a high incidence in China. Few consistent and comparable assessments of BTC disease burden have been conducted at national or subnational levels, and little is known about the demographic, temporal, and geographic patterns of epidemiological characteristics and disease burden of BTC in China. The incidence, mortality, disability-adjusted life-years (DALYs), years of life lost (YLLs) due to premature death and years lived with disability (YLDs) of BTC were comprehensively examined by age, sex, and calendar year in the Chinese population, using the methodological framework and analytical strategies used for the 2021 Global Burden of Disease study.

Improved long-term outcomes after innovative preoperative evaluation and conception of precise surgery for gallbladder cancer.

Background: Three-dimensional visualization preoperative evaluation (3D-VPE) and enhanced recovery after surgery (ERAS) have been suggested to improve outcomes of cancer surgery in patients, yet little is known regarding their clinical benefit in patients with gallbladder cancer (GBC). We hypothesized that the combination of 3D-VPE and ERAS would improve the outcome of patients undergoing surgery for GBC.

Objective: This study aimed to determine if 3D-VPE and ERAS can improve the outcomes and overall survival in patients with GBC, establishing a novel patient management strategy for GBC.

Construction of multilayer films with bactericidal and long-term antitumor drug release properties as a non-vascular stent coating for therapy in obstruction.

The construction of antibacterial and antitumor coatings could offer effective routes to improve the therapeutic effects of non-vascular stents for unresectable obstructions caused by malignant tumours. Herein, polyelectrolyte multilayers have been explored as bactericidal coatings with controlled antitumor drug release. To solve the challenges of loading and controlled release of small-molecule chemotherapeutic drugs in polyelectrolyte multilayers, the antitumor drug doxorubicin (DOX) was chemically conjugated onto polyethylenimine via cis aconitic anhydride (pH-sensitive linker), thus obtaining the polycation prodrug PEI-CA-DOX.

Raman intensity enhancement of molecules adsorbed onto HfS flakes up to 200 layers.

Newly emerging two-dimensional transition metal dichalcogenide HfS2 has received considerable attention recently due to its ultrahigh photoresponsivity, well-balanced carrier mobility and an appropriate band gap which offer potential in electronic and optoelectronic devices. In this work, HfS2 flakes up to 200 layers with varying color contrasts are fabricated and transferred on a SiO2/Si substrate. The Raman intensities of HfS2 flakes and Raman intensities of molecules adsorbed on HfS2 flakes are quantitatively studied both theoretically and experimentally by considering an optical interference effect.

LncRNA-PAGBC acts as a microRNA sponge and promotes gallbladder tumorigenesis.

Long noncoding RNAs (lncRNAs) play roles in the development and progression of many cancers; however, the contributions of lncRNAs to human gallbladder cancer (GBC) remain largely unknown. In this study, we identify a group of differentially expressed lncRNAs in human GBC tissues, including prognosis-associated gallbladder cancer lncRNA (lncRNA-PAGBC), which we find to be an independent prognostic marker in GBC Functional analysis indicates that lncRNA-PAGBC promotes tumour growth and metastasis of GBC cells. More importantly, as a competitive endogenous RNA (ceRNA), lncRNA-PAGBC competitively binds to the tumour suppressive microRNAs miR-133b and miR-511.

MYBL2 is a Potential Prognostic Marker that Promotes Cell Proliferation in Gallbladder Cancer.
