Prospects in the application of ultrasensitive chromosomal aneuploidy detection in precancerous lesions of gastric cancer.

Gastric cancer (GC) is a prevalent malignant tumor within the digestive system, with over 40% of new cases and deaths related to GC globally occurring in China. Despite advancements in treatment modalities, such as surgery supplemented by adjuvant radiotherapy or chemotherapeutic agents, the prognosis for GC remains poor. New targeted therapies and immunotherapies are currently under investigation, but no significant breakthroughs have been achieved.

Efficacy of Sanqi (Radix Notoginseng) in treating cerebral hemorrhage in rats with traumatic brain injury.

Objective: To evaluate the protective efficacy of Sanqi (Radix Notoginseng) on cerebral hemorrhage in a rat model of traumatic brain injury (TBI) by investigating plasminogen activator inhibitor-1 (PAI-1), tissue-type plasminogen activator (t-PA), nuclear factor-κB (NF-κB, p-p65), nitric oxide (NO), endothelin (ET), cluster differentiation (CD61CD62), and coagulation.

Methods: The free-fall method was used to create a rat model of TBI. Forty-eight rats were randomly divided into six groups: the blank group, sham group, model group, low-dose Sanqi (Radix Notoginseng) group, middle-dose Sanqi (Radix Notoginseng) group, and high-dose Sanqi (Radix Notoginseng) group.

Use of autologous platelet rich fibrin-based bioactive membrane in pressure ulcer healing in rats.

Objective: To verify the feasibility of treating pressure ulcers (PUs) with autologous platelet-rich fibrin-based (PRF) bioactive membrane, both in vitro and in vivo.

Method: An animal model using adult male Sprague-Dawley rats was used. Pressure was periodically exerted on the skin to induce localised ischaemia by using an external magnet and transplanted metal disc.

Urokinase Attenuates Pulmonary Thromboembolism in an Animal Model by Inhibition of Inflammatory Response.

Inflammatory response is an important determining factor for the mortality of patients with pulmonary thromboembolism. Inflammatory mediators can promote thrombus formation and increase hemodynamic instability. Urokinase is a commonly used drug for the treatment of PTE.

Dynamic changes of Sonic Hedgehog signaling pathway in gastric mucosa of rats with MNNG-induced gastric precancerous lesions.

Objective: To explore the changes of Sonic Hedgehog (Shh) signaling pathway in the stomach mucosa during the formation of gastric precancerous lesions.

Methods: A total of 72 suckling rats in half genders were randomly and equally divided into the normal group and model group. The rats in the model group were administered with 0.

Effect of electroacupuncture at ST36 on the intestinal mucosal mechanical barrier and expression of occludin in a rat model of sepsis.

Objective: To observe the effect of electroacupuncture (EA) at ST36 on the intestinal mucosal mechanical barrier and expression of the tight junction (TJ) protein, occludin, in a rat model of sepsis.

Methods: 60 male Wistar rats were randomly divided into six groups (n=10 rats each): Control, Control+EA, CLP (caecal ligation and puncture), CLP+EA, CLP+Sham-EA, and Sham-CLP. Rats of the CLP, CLP+EA and CLP+Sham-EA groups underwent CLP modeling of sepsis; those in the Sham-CLP underwent sham surgery and those in the Control and Control+EA groups remained unoperated.

Aspirin modulates the inflammatory response in a thrombus‑stimulated LMVEC model.

The purpose of the present study was to examine whether aspirin interferes with the inflammatory response in a thrombus‑stimulated lung microvascular endothelial cell (LMVEC) model. The LMVECs were randomly divided into eight groups: Normal group (group N), model group (group M), model + ASP group (group M+A), model+CX3CL1‑short hairpin (sh)RNA group (group M+SH), model + CX3CL1‑overexpression vector group (group M+CX3), model + ASP + shRNA group (group M+A+SH), model + ASP + CX3CL1‑overexpression vector group (group M+A+CX3), and normal + virus control group (group N+V). The endothelial cells were cultured, and a thrombus was added to the cells.

Influence of aspirin on the CX3CL1/CX3CR1 signaling pathway in acute pulmonary embolism.

The present study aimed to explore the influence of aspirin on the CX3CL1/CX3CR1 signaling pathway in acute pulmonary embolism (APE) in rats. Our previous study found that CX3CL1/CX3CR1 was increased in APE. However, the effect of this signaling pathway on APE remains unclear.
