1.On Pathology Characteristics of Liver Failing to Maintain Normal Flow of Qi
China Journal of Traditional Chinese Medicine and Pharmacy 2005;0(08):-
This article explored the pathology characteristic of the liver failing to maintain the normal flow of qi.It was considered that syndrome of depression of hepatic qi and reversed syndrome of hepatic qi were the main pathology characteristics of the liver failing to maintain the normal flow of qi,and its origin,development and present situation,as well as its diagnosis evidences and treatment methods and medicine were discussed.It also identified the significance of further standardizing the two syndromes of depression of hepatic qi and reversed of hepatic qi.

Objective:To construct a multi-label learning MRI model for assisting diagnosis of sports injury in knee.Methods:A total of 1 391 knee MRI cases from 1 343 young adults with sports injury in Affiliated Jinling Hospital Nanjing University School of Medicine were retrospectively enrolled. The image cases were randomly divided into training set ( n=973), validation set ( n=139) and test set ( n=279) with ratio of 7∶1∶2. The knee injuries were divided into six categories: meniscus injury, tendon injury, ligament injury, osteochondral injury, synovial bursa disorder and soft tissue injury. Using PyTorch V1.1.0 algorithm package, the Yolo model of deep learning was used to construct the MRI knee joint sports injury detection model. The model was validated on the test set, and the sensitivity, specificity and mean average precision of lesion detection were evaluated. Results:Among the 279 patients in test set, the mean average precision of meniscus injury, tendon injury, ligament injury, osteochondral injury, synovial bursa disorder and soft tissue injury were 83.1%, 89.0%, 88.0%, 85.8%, 85.5% and 83.2%, respectively, and the overall mean average precision was 85.8%. The model was most effective in detecting tendon injury. The sensitivity and specificity of the model for tendon injury were 91.2% and 87.1% respectively.Conclusions:The multi-label MRI knee joint exercise-related injury detection model based on deep learning can effectively assist in detecting the exercise-related injury of knee joint in each tissue structure, and is expected to improve the efficiency of diagnosis and treatment in orthopedics.

This article reviews relevant literature on the prevention and treatment of cancer with hesperidin published in the past 10 years by searching electronic databases such as China National Knowledge Infrastructure(CNKI), Wanfang, and PubMed, and summarizes the research progress on the anticancer mechanism of hesperidin. Hesperidin has a wide range of pharmacological effects, including anti-inflammatory, antioxidant, antibacterial, antiviral, anticancer, immune-regulatory, anti-radiation, neuroprotective and cardiovascular protective properties and so on. Its anticancer mechanisms mainly include inhibiting cancer cell proliferation, promoting apoptosis, reducing angiogenesis, inhibiting invasion and migration of cancer cells, regulating immunity and autophagy, and exerting antioxidant and anti-inflammatory effects. As a broad-spectrum anticancer drug, hesperidin manifests chemo-preventive and therapeutic effects across various cancers, contingent upon its multifaceted anticancer mechanisms. Furthermore, this article summarizes the synergistic effects of hesperidin in combination with cisplatin, doxorubicin, cyclophosphamide and paclitaxel. It elucidates that hesperidin can enhance the cytotoxicity of these anticancer drugs against cancer cells while mitigating drug resistance and adverse side effects. Nonetheless, the clinical use is somewhat constrained due to its poor water solubility and limited bioavailability. Therefore, this article also outlines the current strategies for enhancing hesperidin's bioavailability, including structural modification, combination with other chemical substances, and utilization of nano drug carriers.The discovery of derivatives of hesperidin not only preserves the anticancer efficacy of hesperidin, but also effectively overcomes the shortcomings of poor water solubility and low bioavailability of hesperidin, effectively predicting the good application prospects of hesperidin and its derivatives.
