Leptomeningeal metastasis occurs in approximately 5% of patients with metastatic solid carcinomas, and it is often diagnosed in patients with breast cancer, lung cancer, malignant melanoma, and digestive cancer. Herein, we report a case of a metastatic cancer of unknown primary origin. The leptomeningeal metastasis progressed quite rapidly, and the patient died despite achieving complete remission via second-line chemotherapy.

In the face of forest fire emergencies, fast and efficient dispatching of rescue vehicles is an important means of mitigating the damage caused by forest fires, and is an effective method of avoiding secondary damage caused by forest fires, minimizing the damage caused by forest fires to the ecosystem, and mitigating the losses caused by economic development. this paper takes the actual problem as the starting point, constructs a reasonable mathematical model of the problem, for the special characteristics of the emergency rescue vehicle scheduling problem of forest fires, taking into account the actual road conditions in the northern pristine forest area, through the analysis of the cost of paths between the forest area and the highway, to obtain the least obstructed rescue paths, to narrow the gap between the theoretical model and the problem of the actual. Improvement of ordinary genetic algorithm, design of double population strategy selection operation, the introduction of chaotic search initialization population, to improve the algorithm's solution efficiency and accuracy, through the northern pristine forest area of Daxing'anling real forest fire cases and generation of large-scale random fire point simulation experimental test to verify the effectiveness of the algorithm, to ensure that the effectiveness and reasonableness of the solution to the problem of forest fire emergency rescue vehicle scheduling program.

Article Synopsis
- Heterotopic ossification (HO) in the elbow leads to limited movement and is often caused by injuries like burns or trauma; this study analyzes the long-term outcomes of 51 elbows treated surgically.
- The study followed 48 patients over an average of 8 years, assessing metrics such as elbow movement arcs, pain levels, and functional performance scores post-surgery.
- Results showed significant improvement in elbow functionality, but patients with type II diabetes experienced the lowest movement range and higher complication rates, indicating potential risk factors for poorer outcomes.
Ultrasound-Guided Repair of the Anterior Talofibular Ligament With or Without Gould Augmentation Is Safe and Improves Clinical Outcomes for Chronic Lateral Ankle Instability: A Case Series of 49 Patients.

Objectives: We have previously shown that ultrasound-guided repair results in an accurate anchor placement and restores ankle joint stability using cadaveric models. The objective is to assess the safety and clinical outcomes of ultrasound-guided ATFL repair with or without augmentation.
Methods: Forty-nine patients with chronic lateral ankle instability underwent ultrasound-guided ATFL repair with or without augmentation.

Background: Hepatitis E virus (HEV) is a leading cause of acute viral hepatitis, particularly in Asia and Africa, where HEV genotypes 1 and 2 are prevalent. Although a recombinant vaccine, Hecolin, is available, it has not been used to control outbreaks. The licensed three-dose regimen might pose challenges for it to be an impactful outbreak control tool.
