Thyroid nodules are a common endocrine disorder, and their early detection and accurate diagnosis are crucial for the prevention of thyroid cancer. However, the highly heterogeneous morphology and boundaries of thyroid nodules pose significant challenges to their precise identification and classification. Traditional diagnostic approaches rely heavily on physicians' experience, which increases the risk of misdiagnosis and missed diagnoses. With the rapid advancement of computer-aided diagnosis (CAD) technologies, applying deep learning algorithms to the analysis of thyroid nodule ultrasound images has shown great potential. This paper reviews the latest research progress on deep learning-based CAD methods for thyroid nodules, with a focus on their applications in image preprocessing, segmentation and classification. The advantages and limitations of current techniques are analyzed, and potential future directions are discussed. This review aims to highlight the potential of deep learning in thyroid nodule diagnosis and to provide a foundation for selecting feasible pathways for future clinical applications.

As one of the core pathogenesis during treatment with traditional Chinese medicine,liver heat runs through different stages of liver disease. The interpretation of its meaning in different medicine categories(traditional Chinese medicine,Tibetan medicine,Mongolian medicine,Uygur medicine,Dai medicine,Yao medicine,etc.) is not unified, and the phenomena of the same name with different meanings,confusion, and misappropriation emerge. This seriously restricts the inheritance,innovation, and clinical application of traditional Chinese medicine and ethnomedicine. By tracing and analyzing liver heat, it is found that liver heat in traditional Chinese medicine is caused by disordered rest and diet, as well as internal injury due to emotional disorder, which leads to liver dysfunction, Qi stagnation, and heat turning to fire in the liver meridian. The liver heat in Tibetan medicine is caused by the accumulated heat of the liver nature and the evil heat in the liver, which stimulates the toxin of Chiba fever. The liver heat in Mongolian medicine derives from the abnormal diet and rest, making excessive Sheila accumulate in the liver and causing disease. The above etiologies are all related to diet, rest,exogenous evil,emotion,and so on, and the pathogenesis is related to the imbalance of Qi and the metabolic disorder of organs. The clinical symptoms are pain in the liver region,yellow eyes, bitter mouth, fever,digestion,and loss of appetite. The principle of treatment and compatibility of prescription are heat-based, with auxiliary detoxification. Other ethnomedicine, such as Uygur medicine, Dai medicine, Yao Medicine,Miao medicine, and She medicine do not have a clear discussion on liver heat,and their etiology, pathogenesis, treatment,and prescription are not systematic,mostly based on a single drug or proven prescriptions.Through the systematic tracing,mining,induction,analysis, and arrangement of the liver heat based on existing literature information database in China,this paper regarded syndrome as the outline and disease as the goal,clarified the similarities and differences of the pathogenesis of liver heat in traditional Chinese medicine,and determined the relationship between liver heat and liver disease and the status quo of syndrome and treatment.This review provides evidence and reference for clinical prevention and treatment,as well as drug development for liver disease.

Objective To investigate the current status of hepatitis B virus (HBV) infection among hospitalized patients aged 1-18 years, as well as the status of immunity after hepatitis B vaccination. Methods Related data were collected from the patients aged 1-18 years who were hospitalized in Henan Provincial People's Hospital from July 2020 to July 2021, including serological markers for hepatitis B (HBsAg, anti-HBs, HBeAg, anti-HBe, and anti-HBc) and hepatitis B vaccination. The epidemiological situation of HBV infection was analyzed, as well as the immune effect after vaccination. The trend chi-square test was used for trend analysis. Results A total of 10 658 hospitalized patients were collected, among whom there were 6 372 male patients (59.79%) and 4 286 female patients (40.21%). In this population, the patients with positive HBsAg accounted for 0.28% (30/10 658), with a relatively high proportion of 0.68% and 0.62%, respectively, in the 17-and 18-year age groups; the patients with positive anti-HBs accounted for 51.82% (5 523/10 658), with a relatively high proportion of > 63% in the 1-4 years age groups, and there was a reduction in the proportion of patients with positive anti-HBs (fluctuating around 40%) in the 5-18 years age groups. With the increase in age, the positive rate of anti-HBs tended to decrease in both male and female patients (male: χ 2 =8.217, P =0.004; female: χ 2 =10.048, P =0.002). Conclusion Based on the data of hospitalized patients, HBV infection in the population aged 1-18 years in Henan Province has the characteristics of low prevalence rate and high immunity, and the reduction in the proportion of patients with positive anti-HBs at more than five years after vaccination should be taken seriously in this region.

OBJECTIVE: To investigate the proportion of 8 kinds of ginsenoside to ginsenoside Rg1 in Panax ginseng and the regularity of growth year in Jilin province, and to provide reference for the identification of growth year. METHODS: The samples of garden ginseng, wild-cultivated ginseng and wild ginseng were collected from different growth years (3-30 years) in Jilin province. The contents of 8 ginsenoside (ginsenoside Rg1, Re, Rf, Rb1, Rc, Rb2, Rb3, Rd) in P. ginseng were determined by HPLC. The contents of saponins as well as the proportion of 8 kinds of ginsenoside to ginsenoside Rg1 were calculated; the relationship of the proportion with growth year was investigated. RESULTS: As the increase of growth year, the proportion of 8 kinds of ginsenosides in garden ginseng to ginsenoside Rg1 as well as that of ginsenoside Re, Rb1, Rc, Rd to ginsenoside Rg1 were decreased gradally (P<0.001); the proportion of ginsenoside Re to ginsenoside Rg1 in wild-cultivated ginseng decreased first and then increased(P<0.001); the proportion of 8 kinds of ginsenosides to ginsenoside Rg1 as well as the proportion of ginsenoside Re and Rb1 to ginsenoside Rg1 were increased gradually in wild ginseng (P<0.001); the proportion of ginsenoside Rf, Rb3 to ginsenoside Rg1 in garden ginseng, wild-cultivated ginseng and wild ginseng had no significant difference(P>0.05). CONCLUSIONS: Garden ginseng, wild-cultivated ginseng and wild ginseng contain 8 kinds of ginsenosides. The growth year can be predicted preliminarily according to the proportion of ginsenoside Rg1 and ginsenoside Re, Rb1 to ginsenoside Rg1.
