As a mercury-containing elixir， Hongshengdan has been known as a sacred medicine for surgery by ancient medical practitioners because of its precise curative effects. It originated from Yizong Shuoyue in the Qing dynasty， Qing dynasty and modern medical practitioners have adapted and modified its formula for clinical application. Employing bibliometric methods， the authors systematically organized relevant ancient literature of the Qing dynasty and modern literature， and analyzed the composition and dosage， preparation method， and clinical application. Among the 25 ancient books concerning Hongshengdan， a total of 12 medicinal formulas， 15 refining methods and 9 clinical applications were obtained. Research confirms that Hongshengdan consisted of mercury， saltpeter， alum， soap alum， cinnabar and realgar. Using measurement conversion standards of Qing dynasty， the modern single-batch formulation comprised 37.30 g of mercury， 149.20 g of saltpeter， 37.30 g of alum， 22.38 g of soap alum， 18.65 g of cinnabar， and 18.65 g of realgar. In modern refining of Hongshengdan， most medical practitioners take the core medicines， with dosages approximately 30 g of mercury， 30 g of saltpeter， and 30 g of alum. Refining method involves pretreatment stewing the materials during preparation， and alum， soap alum， and saltpeter are first ground together， then combined with mercury， cinnabar， and realgar for grinding until mercury and other drugs grind to the degree of no star points. The mixture is then placed in a pot or vessel by cold-forming method. After covering， the opening is sealed using either raw gypsum salt mud or honey-dipped cotton paper strips. Sand is packed around the vessel and then pressurized. During the calcination process， begin with a low flame（30 min）， then increase to a medium flame（30 min）， followed by a high flame（30 min）， after removing fire toxins， collect the final product. Hongshengdan has the efficacy of lifting the poison， removing the corrosion， producing muscle and dispersing， and is often used in the treatment of surgical sore and carbuncle type of diseases. Modern research indicates that Hongshengdan is commonly used to treat skin system diseases such as ulcers and herpes. The aforementioned findings provide a reference basis for the subsequent refining method and clinical application of Hongshengdan.

Metabolic dysfunction-associated steatotic liver disease (MASLD) comprises a spectrum of liver injuries, including steatosis to steatohepatitis (MASH), liver fibrosis, cirrhosis, and relevant complications. The liver mainly comprises hepatocytes, liver sinusoidal endothelial cells (LSECs), Kupffer cells (KCs), immune cells (T cells, B cells), and hepatic stellate cells (HSCs). Crosstalk among these different liver cells, endogenous aberrant glycolipid metabolism, and altered gut dysbiosis are involved in the pathophysiology of MASLD. This review systematically examines advances in understanding the molecular pathogenesis of MASLD, with a focus on emerging therapeutic targets and translational clinical trials. We first delineate the crucial regulatory mechanisms involving diverse liver cells and the gut-liver axis in MASLD development. These cell-specific pathogenic insights offer valuable perspectives for advancing precision medicine approaches in MASLD treatment. Furthermore, we evaluate potential therapeutic targets and summarize clinical trials currently underway. By comprehensively updating the MASLD pathophysiology and identifying promising strategies, this review aims to facilitate the development of novel pharmacotherapies for this increasingly prevalent condition.

Hongsheng Dan, historically referred to as the "surgical sacred medicine", is at risk of losing its refining technology in contemporary times. This study aimed to preserve and innovate this traditional non-heritage refining technology. By utilizing the analytic hierarchy process(AHP) combined with the entropy weight method, this study established the hierarchical structure model of refining process of Hongsheng Dan and conducted a single factor experiment and an L_9(3~4) orthogonal experiment to optimize the refining method of Hongsheng Dan. Additionally, the study employed infrared thermal imaging to monitor temperature variations of Hongsheng Dan during the refining process. The optimized refining parameters for Hongsheng Dan were established as follows: a slow fire temperature of 175 ℃ with a duration of 30 minutes, a strong fire temperature of 270 ℃ with a duration of 60 minutes, and a tail fire temperature of 180 ℃ with a duration of 15 minutes. The stability and feasibility of this optimized process were confirmed through validation tests. The research focused on the material transformation of Hongsheng Dan, starting from the material changes during the refining process of Hongsheng Dan and the synthesis of mercuric oxide from nitric acid. The study investigated elemental transformations, physical phase changes, and alterations in thermal properties. 78.98% of the mercury in Hongsheng Dan and 80.21% of the mercury in mercuric oxide from nitric acid were retained. The diffraction peak intensity of the(011) crystal plane of Hongsheng Dan was highest at approximately 30.07°, indicating that the(011) crystal plane had a preferred crystalline orientation. Furthermore, the temperature range for the alteration in thermal properties during the refining process of Hongsheng Dan was found to be between 80 ℃ and 130 ℃. This research not only optimized the refining technology of Hongsheng Dan but also pioneered the application of infrared thermal imaging to study temperature changes throughout the refining process. By exploring the material transformation patterns of Hongsheng Dan and the synthesis of mercuric oxide from nitric acid, the study provided technical support for the preservation and innovation of Hongsheng Dan.

Background and purpose: Since the detection of renal neoplasm is increasing, it's important to distinguish myomatous angiomyolipoma (mAML) from malignant tumors. This study aimed to investigate the imaging features of renal mAML on computer tomography (CT) and improve the accuracy of diagnosis and differential diagnosis. Methods: Ten patients were diagnosed with mAML. The cases were composed of 4 men and 6 women, with a mean age of 53.2 years (range 38-64). Among all of the cases, the percentage of spindle cell is more than 70%. Two radiologists reviewed all of the images to evaluate general characteristics, imaging features on unenhanced CT and enhanced CT. The mean attenuation on the unenhanced CT of mAML, normal renal parenchyma and skeletal muscle was compared by the paired-sample t test. Results: Among all of the tumors, nine lesions were solitary, and the other one was accompanied with typical AML. Six lesions were at the left kidney while four lesions were at the right side. Five lesions located intracapsularly. All the lesions were well-defined, nine of them were regular. The tumor sizes ranged from 15 to 80 mm with mean (43±19) cm. Intratumoral macroscopic fat, cystic degeneration and vessels were found in two lesions, two lesions and three lesions, respectively. Calcification or hemorrhage was not detected in any cases. On unenhanced CT, 70% cases were hyperattenuating. Eight cases were homogeneous or slightly heterogeneous. The mean attenuation of the tumor lesions on unenhanced CT was (48.60±5.50) HU, which was higher than that of normal renal parenchyma (39.70±6.67) HU (P<0.05), and similar to that of skeletal muscle (48.9±2.28) HU (P>0.05). After intravenous injection of contrast media, seven cases were categorized as the slightly heterogeneous or heterogeneous enhancement type. Four cases showed a weak enhancement whereas five cases were with a moderate enhancement. The gradual, prolonged and early washout enhancement patterns were observed in 40%, 40%, and 20% of the cases, respectively. Conclusion: The radiological appearance of mAML had a tendency to be hyperattenuating on unenhanced CT images without macroscopic fat; it could be homogeneous or slightly heterogeneous on unenhanced scans. After the injection of contrast agent, mAML tended to have a weak or moderate, lightly heterogeneous to heterogeneous enhancement, and it could demonstrate gradual and prolonged enhancement patterns.

Oral glucose tolerance test(OGTT)was performed in 419 first-degree relatives(FDRs)of type 1 diabetes mellitus. GADA, IA-2A, and IAA were determined by radioligand assay, and the positive rates were 7.16%, 1.43%, and 1.26%, respectively. Intravenous glucose tolerance test(IVGTT)and nateglinide-OGTT were performed in 39 controls, 11 first-degree relatives with positive autoantibody(Ab+group), 14 ones with negative autoantibody(Ab-group)during 5-7 days.The first-phase insulin release(FPIR), area under insulin release during 0-10 min [AUC0-10] of IVGTT and the value of(ΔI30/ΔG30)of nateglinide-OGTT in Ab+group were lower than those of control and(2.75±0.37 vs 3.61±1.05)mU/mmol, all P＜0.05]. The 1st min insulin release in Ab+group was lower than that of Ab-group [(3.80±0.30 vs 4.52±0.70)mU/L, P＜0.05]. The HOMA-IR was higher in Ab-group than that in control group(2.92±1.04 vs 1.96±1.22, P＜0.05). The results suggest that the positivity rates of autoantibodies in FDRs of type 1 diabetes mellitus are very close to those of Caucasian. There exist insulin secretion defects in FDRs with positive autoantibody while insulin resistance in FDRs with negative autoantibody.
