Large language models (LLMs) such as ChatGPT, Claude, Llama, and Qwen are emerging as transformative technologies for the diagnosis and treatment of various diseases. With their exceptional long-context reasoning capabilities, LLMs are proficient in clinically relevant tasks, particularly in medical text analysis and interactive dialogue. They can enhance diagnostic accuracy by processing vast amounts of patient data and medical literature and have demonstrated their utility in diagnosing common diseases and facilitating the identification of rare diseases by recognizing subtle patterns in symptoms and test results. Building on their image-recognition abilities, multimodal LLMs (MLLMs) show promising potential for diagnosis based on radiography, chest computed tomography (CT), electrocardiography (ECG), and common pathological images. These models can also assist in treatment planning by suggesting evidence-based interventions and improving clinical decision support systems through integrated analysis of patient records. Despite these promising developments, significant challenges persist regarding the use of LLMs in medicine, including concerns regarding algorithmic bias, the potential for hallucinations, and the need for rigorous clinical validation. Ethical considerations also underscore the importance of maintaining the function of supervision in clinical practice. This paper highlights the rapid advancements in research on the diagnostic and therapeutic applications of LLMs across different medical disciplines and emphasizes the importance of policymaking, ethical supervision, and multidisciplinary collaboration in promoting more effective and safer clinical applications of LLMs. Future directions include the integration of proprietary clinical knowledge, the investigation of open-source and customized models, and the evaluation of real-time effects in clinical diagnosis and treatment practices.

A novel technology is proposed for non-contact and real-time detection of atrial fibrillation using millimeter-wave radar.A 60 GHz PCR millimeter wave radar is used to continuously detect the chest echo signal of the subject.After signal acquisition,I-Q signal is generated through I-Q demodulation,and the signal phase information is extracted using effective points phase trend evaluation for obtaining the signals from oscillations in the chest wall,from which the respiratory signals and cardiac signals are extracted through digital filtering for the analysis of cardiac movement.Whether the atrial fibrillation occurs or not is determined by the characteristics of atrial fibrillation wave in the time domain.The effective points phase trend evaluation for extracting more accurate signal phase information and the time-domain method for real-time atrial fibrillation detection are the innovations of the study.The experimental results show that the proposed method achieves a detection accuracy of 99.2%in clinic.

ObjectiveTo investigate the objective characteristics of tongue manifestations in patients with coronary heart disease (CHD). MethodsA total of 315 participants with CHD were recruited in the CHD group, and 211 healthy participants who underwent physical examination were recruited as the healthy control group. In addition, according to the common comorbidities (primary hypertension, carotid atherosclerosis, type 2 diabetes mellitus, fatty liver, hyperlipidaemia, heart failure, and cerebral infarction) in 315 participants with CHD, each comorbidity was classified into a group of comorbidities with that disease and a group of non-comorbidities. Tongue images were captured using a TFDA-1 tongue diagnostic instrument to characterise the tongue body (TB) and tongue coating (TC), comparing the RGB, HIS, and Lab colour spaces in the chromaticity index (R, red; G, green; B, blue; H, hue; I, intensity; S, saturation; L, lightness; a, red-green axis; b, yellow-blue axis), the tongue coating thickness index (per-All), contrast (CON), angular second moment (ASM), entropy (ENT), and mean (MEAN) in texture metrics. ResultsCompared with the healthy control group, the characteristic indexes of tongue body in CHD group showed lower TB-R, TB-G, TB-B, TB-I, TB-L and higher TB-H, TB-b; and the characteristic indexes of tongue coating in CHD group showed lower TC-R, TC-B and higher TC-CON, TC-MEAN, TC-H, TC-b (P<0.05 or P<0.01). Compared with non-combined primary hypertension group, CHD combined primary hypertension group showed higher per-All, TB-G, TB-L, and lower TB-a, TC-a (P<0.05); compared with the non-combined carotid atherosclerosis group, CHD combined carotid atherosclerosis group showed higher TB-CON, TB-ENT, TB-MEAN, and lower TB-ASM (P<0.05 or P<0.01); compared with the non-combined type 2 diabetes mellitus group, CHD combined type 2 diabetes mellitus group showed lower per-All and higher TB-H (P<0.05 or P<0.01); compared with the non-combined fatty liver group, CHD combined fatty liver group showed higher TB-CON, TB-MEAN, TB-ENT, and lower TB-ASM and TC-S (P<0.05 or P<0.01); compared with the non-combined hyperlipidaemia group, CHD combined hyperlipidaemia group showed lower TB-S and TB-a (P<0.05); compared with non-combined heart failure group, CHD combined heart failure group showed lower TB-R, TB-G, TB-I, TB-L, and higher TB-a (P<0.05 or P<0.01); compared with non-combined cerebral infarction group, CHD combined cerebral infarction group showed higher TC-CON, TC-ENT, TC-MEAN, and lower TC-ASM (P<0.05 or P<0.01). ConclusionCompared to healthy individuals, patients with CHD tend to have darker tongue colours and rougher TC textures. Compared with non-comorbidity participants, those with primary hypertension tended to be lighter tongue colour and thicker tongue coating, those with carotid atherosclerosis had paler tongue body, those with type 2 diabetes mellitus had thinner tongue coating, those with fatty liver disease had paler tongue body and whiter tongue colour, those with hyperlipidaemia and heart failure had paler tongue colour, and those with cerebral infarction had rougher tongue texture.

This study explored the feasibility of mineral element content and ratios of nitrogen isotopes to discriminate the cultivation mode of Dendrobium nobile in order to provide theoretical support for the discrimination of the cultivation mode of D. nobile. The content of 11 mineral elements(N, K, Ca, P, Mg, Na, Fe, Cu, Zn, Mn, and B) and nitrogen isotope ratios in D. nobile and its substrate samples in three cultivation methods(greenhouse cultivation, tree-attached cultivation, and stone-attached cultivation) were determined. According to the analysis of variance, principal component analysis, and stepwise discriminant analysis, the samples of different cultivation types were classified. The results showed that the nitrogen isotope ratios and the content of elements except for Zn were significantly different among different cultivation types of D. nobile(P<0.05). The results of correlation analysis showed that the nitrogen isotope ratios, mineral element content, and effective component content in D. nobile were correlated with the nitrogen isotope ratio and mineral element content in the corresponding substrate samples to varying degrees. Principal component analysis can preliminarily classify the samples of D. nobile, but some samples overlapped. Through stepwise discriminant analysis, six indicators, including δ~(15)N, K, Cu, P, Na, and Ca, were screened out, which could be used to establish the discriminant model of D. nobile cultivation methods, and the overall correct discrimination rates after back-substitution test, cross-check, and external validation were all 100%. Therefore, nitrogen isotope ratios and mineral element fingerprints combined with multivariate statistical analysis could effectively discriminate the cultivation types of D. nobile. The results of this study provide a new method for the identification of the cultivation type and production area of D. nobile and an experimental basis for the quality evaluation and quality control of D. nobile.

Objective: To observe the effect of Mo-Rubbing abdomen manipulation on glucose metabolism and inflammatory factors in rats with type 2 diabetes mellitus (T2DM). Methods: Sixty Sprague-Dawley rats were randomly divided into a normal group (n=10) and a group for modeling (n=50) using the random number table method. Rats in the group for modeling were induced to form T2DM models by a high-sugar and high-fat diet combined with intraperitoneal injection of streptozotocin. Thirty successfully modeled rats were randomly divided into a model group, a Mo-Rubbing abdomen group, and a metformin group, with 10 rats in each group. Rats in the normal group and the model group received no intervention, those in the Mo-Rubbing abdomen group received Mo-Rubbing abdomen manipulation, and those in the metformin group received metformin by gavage. After 8-week intervention, fasting insulin (FINS), fasting plasma glucose (FPG), homeostasis model assessment for insulin resistance (HOMA-IR) and area under the curve at the oral glucose tolerance test (AUC-OGTT), as well as serum inflammatory factors interleukin (IL)-1β, IL-6, and tumor necrosis factor (TNF)-α were detected, and the morphological changes of the pancreas were also observed. Results: After the 8-week intervention, the levels of FINS, FPG, HOMA-IR, and AUC-OGTT of rats in the Mo-Rubbing abdomen group were significantly lower than those in the model group (P<0.05); the pancreatic injury degree in the Mo-Rubbing abdomen group and the metformin group was lower than that in the model group. Compared with the model group, the serum IL-1β, IL-6, and TNF-α levels of rats in the Mo-Rubbing abdomen group were significantly decreased (P<0.05), and the serum IL-1β and TNF-α levels of the metformin group showed a downward trend; the serum IL-6 and TNF-α levels in the Mo-Rubbing abdomen group were significantly lower than those in the metformin group (P<0.01). There was a significant positive correlation between FPG with IL-1β, IL-6, and TNF-α in the T2DM rats (P<0.01). Conclusion: Mo-Rubbing abdomen manipulation reduces the inflammatory response and improves the morphological changes of the pancreas in T2DM rats, thereby achieving the effect of lowering blood glucose.
