3D embedded bioprinting of large-scale intestine with complex structural organization and blood capillaries.

Accurate reproduction of human intestinal structure and functionis of great significance for understanding the development and disease occurrence of the gut. However, moststudies are often confined to 2D models, 2.5D organ chips or 3D organoids, which cannot fully recapitulate the tissue architecture, microenvironment and cell compartmentalization found.

An in-depth study on the magnetic resonance imaging characteristics of tendon rupture in sports injuries and its correlation with patients' clinical symptoms.

Muscle injuries, such as Achilles and quadriceps tendon ruptures, pose a significant challenge in elite sports, accounting for more than 30% of all sports-related injuries. Our primary goal is to investigate the MR imaging characteristics of tendon rupture in sports injuries and their relationship with patients' clinical symptoms. In our retrospective study at Zhejiang University of Traditional Chinese Medicine's Second Affiliated Hospital (Zhejiang Xinhua Hospital), we compared the clinical presentation and MRI results of 106 patients with isolated AT and QT ruptures.

Nano-SAR Modeling for Predicting the Cytotoxicity of Metal Oxide Nanoparticles to PaCa2.

Nowadays, the impact of engineered nanoparticles (NPs) on human health and environment has aroused widespread attention. It is essential to assess and predict the biological activity, toxicity, and physicochemical properties of NPs. Computation-based methods have been developed to be efficient alternatives for understanding the negative effects of nanoparticles on the environment and human health.

[Effect of two methods on postoperative shoulder pain following laparoscopic cholecystectomy].

Objective: To investigate the effect of two methods on postoperative shoulder pain following laparoscopic cholecystectomy (LC).

Methods: A total of 99 patients undergoing LC were prospectively divided into three groups (33 patients in each group): Patients in group A underwent LC were control group, those in group B were inserted negative pressure drainage tube under the right inferior phrenic after LC, and patients in group C accepted warm and normal saline flush during operation under the right inferior phrenic. Shoulder pain occurrence and shoulder pain levels (visual analogue pain scale-VAS) were recorded on 1, 3, 6, 24, 48, 72 h after operation.
