Muscle Strength Decline Caused by Eperisone Hydrochloride: A Case Report

A 65-year-old female with thoracic spinal stenosis and incomplete paraplegia underwent T11-T12 posterior thoracic interbody fusion. During postoperative rehabilitation, she experienced thigh pain, involuntary lower limb convulsions, and muscle fatigue. Despite being prescribed eperisone hydrochloride for relief, her muscle strength decreased after 14 doses. This adverse effect, not listed in the latest Chinese medication instructions, subsided 4 days after discontinuation. This case suggests eperisone hydrochloride potentially caused reversible muscle strength decline, highlighting its potential unsuitability for incomplete paraplegia patients due to possible further muscle strength reduction. We propose updating the medication instructions to alert clinicians to this risk.

Pancreatic cancer: A review of epidemiology, trend, and risk factors

Despite rapid advances in modern medical technology and significant improvements in survival rates of many cancers, pancreatic cancer is still a highly lethal gastrointestinal cancer with a low 5-year survival rate and difficulty in early detection. At present, the incidence and mortality of pancreatic cancer are increasing year by year worldwide, no matter in the United States, Europe, Japan, or China. Globally, the incidence of pancreatic cancer is projected to increase to 18.6 per 100000 in 2050, with the average annual growth of 1.1%, meaning that pancreatic cancer will pose a significant public health burden. Due to the special anatomical location of the pancreas, the development of pancreatic cancer is usually diagnosed at a late stage with obvious clinical symptoms. Therefore, a comprehensive understanding of the risk factors for pancreatic cancer is of great clinical significance for effective prevention of pancreatic cancer. In this paper, the epidemiological characteristics, developmental trends, and risk factors of pancreatic cancer are reviewed and analyzed in detail.

The Distributional Characteristic and Growing Trend of Pancreatic Cancer in China

Pancreatic cancer is a malignant tumor with difficulty in diagnosis and treatment and was the sixth leading cause of cancer death among both men and women in China. The 5-year relative survivals of pancreatic cancer were only 7.2% in China and the lowest level in all cancers. The proportion of estimated new cases of pancreatic cancer in China was comparatively high in East China, Northeast, North China, and Northwest and relatively low in Central China, Southwest, and South China, showing obvious regional characteristics. It implies that the incidence and mortality in the eastern region are significantly higher than those in the western region, which is consistent with the result that the incidence and mortality increased from low to middle to high urbanization areas in China, and the prevalence of diabetes increased from underdeveloped to intermediately developed to developed region.

Pancreatic cancer and associated exosomes

Pancreatic cancers with poor prognosis are highly malignant, readily metastatic and of immune tolerance, mainly due to delayed detection. The metastatic progression and immune tolerance of pancreatic cancer is greatly attributed to the intercellular communication. However, exosomes are deemed to be the most important tool of intercellular communicators. Thus, we present a review of pancreatic cancer and exosomes in this article. We intensively summarize the progress of early pancreatic cancer and the relationship of the proliferation, progression and metastasis of pancreatic cancer and pancreatic cancer-derived exosomes, and propose new ideas of the study of pancreatic cancer.
