ObjectiveTo observe the effects of Yifei Tongluo prescription on the NOD-like receptor protein 3 (NLRP3)/Caspase-1/gasdermin D (GSDMD) pathway and epithelial-mesenchymal transition (EMT) in rats with pulmonary fibrosis. MethodsTracheal instillation of bleomycin was conducted to establish a rat model of pulmonary fibrosis. Thirty Sprague-Dawley (SD) rats were randomly divided into a blank group, a model group, a prednisone acetate group (1.17 mg·kg-1), and low- and high-dose Yifei Tongluo prescription groups (10.62 and 21.24 g·kg-1, respectively). Administration started on the 7th day after modeling, once a day for 28 consecutive days. The lung coefficient of each group was calculated. The pathological changes of lung tissues in each group were observed by hematoxylin-eosin (HE) staining and Masson staining. The expression of α-smooth muscle actin (α-SMA) and vimentin in rat lung tissues was detected by immunohistochemistry. The expression of NLRP3 inflammasome, E-cadherin (E-cad), and typeⅠ collagen (ColⅠ) in lung tissues was detected by immunofluorescence. The content of hydroxyproline (HYP), tumor necrosis factor (TNF)-α, interleukin (IL)-18, and IL-1β in rat serum was detected by enzyme-linked immunosorbent assay (ELISA). The mRNA expression levels of NLRP3, apoptosis-associated speck-like protein containing a CARD (ASC), IL-1β, and transforming growth factor (TGF)-β1 in rat lung tissues were determined by real-time quantitative polymerase chain reaction (Real-time PCR). The protein expression levels of NLRP3, GSDMD, ASC, and Caspase-1 in rat lung tissues were determined by Western blot. ResultsCompared with the blank group, the model group exhibited a significantly increased lung coefficient (P<0.01) and significantly increased range of pulmonary interstitial inflammation and collagen deposition. In addition, the levels of α-SMA, Vimentin, E-cad, and ColⅠ in lung tissues were significantly increased (P<0.01). The levels of fibrosis- and inflammation-related factors HYP, TNF-α, IL-18, and IL-1β in serum were significantly upregulated (P<0.01). The levels of factors related to the activation of NLRP3 inflammasome in lung tissues, including NLRP3, GSDMD, ASC, Caspase-1, IL-1β, and TGF-β1, were significantly upregulated (P<0.01). Compared with the model group, the Yifei Tongluo prescription groups showed improved lung coefficients. Additionally, the extent of lung inflammation and collagen deposition was significantly reduced. The expression of α-SMA, Vimentin, E-cad, and ColⅠ in lung tissue was significantly decreased (P<0.01). The levels of HYP, TNF-α, IL-18, and IL-1β in serum were significantly reduced (P<0.01). The expression levels of NLRP3, GSDMD, ASC, Caspase-1, IL-1β, and TGF-β1 in lung tissue were also significantly decreased (P<0.01). ConclusionYifei Tongluo prescription can regulate the NLRP3/Caspase-1/GSDMD pathway, down-regulate release of pro-inflammatory and pro-fibrotic cytokines, alleviate NLRP3 inflammasome-mediated pyroptosis and EMT, and thereby improve pulmonary fibrosis in rats.

Objective To explore the adverse event signals of children using macrolide drugs (azithromycin, clarithromycin, and erythromycin), and provide reference for rational medicine use in clinical practice. Methods Data from children under 12 years old were extracted from the US FAERS database spanning from the first quarter of 2004 to the second quarter of 2023. The adverse drug reaction (ADR) signal mining for three macrolide antibiotics was conducted using the Reporting Odds Ratio (ROR) and Bayesian Confidence Propagation Neural Network (BCPNN) methods. Special emphasis was placed on analyzing and contrasting the differences in adverse events among the three drugs. Results A total of 1 615 reports for children under 12 years old were retrieved from the FAERS database, including 1 024 reports of azithromycin, 460 reports of clarithromycin, and 131 reports of erythromycin. Among azithromycin and erythromycin, there were more reports from boys than girls, while for clarithromycin, there were more reports from girls than boys. Oral administration was the most common route of administration for all three drugs. Regarding the outcome of adverse events reported, azithromycin and clarithromycin were primarily associated with other serious adverse events, whereas erythromycin was mainly associated with hospitalization and other serious adverse events. The number of adverse events reported decreased with increasing age, with a higher number of reports in the 0-3 age group. Using the ROR and BCPNN methods for signal detection, 86 signals were identified for azithromycin, 91 for clarithromycin, and 34 for erythromycin. These signals involved 22 System Organ Classes (SOCs), with azithromycin mainly concentrated in skin and subcutaneous tissue disorders (n=21), clarithromycin in gastrointestinal disorders (n=15), and erythromycin in gastrointestinal disorders (n=8). Twenty-four signals of moderate to high risk were detected, with 13 for azithromycin, 9 for clarithromycin, and 2 for erythromycin. Conclusion The adverse events induced by the three drugs with different risks in different systems. When clinically treating Mycoplasma pneumoniae pneumonia in children, the risk profiles of drugs in different systems should be considered, and personalized dosing should be implemented.

To summarize Professor GAO Shuzhong's clinical experience in treating idiopathic tinnitus with a combination of acupuncture and Chinese meteria medica. It is believed that idiopathic tinnitus is mostly caused by weak lungs and spleen, kidney essence deficiency, liver constraint transforming into fire, and binding constraint of heart qi. Treatment advocates the combination of acupuncture and Chinese meteria medica in clinical practice. Acupuncture treatment mainly focus on the method of opening the orifices by syndrome identification in combination with Ermen (TE 21), Tinggong (SI 19), Tinghui (GB 2), Shenmai (BL 62) to regulate qi and blood, and supporting with Baihui (GV 20), Yintang (EX-HN 3), Taichong (LR 3), and Yanglingquan (GB 34) to soothe the liver, resolve constraint, and calm the mind. Oral administration of Chinese medicinal prescription usually includes modified Yiqi Congming Decoction (益气聪明汤) and Tongqi Powder (通气散), and the external administration of Chinese medicinal prescription can apply self-prescribed Wenqing Powder (温清散) to navel moxibustion.

The rapid development of artificial intelligence (AI) technology provides new opportunities for the modernisation of traditional Chinese medicine (TCM) diagnosis. By analysing the foundation, research progress and difficulties of the combination of AI and TCM diagnosis, it is concluded that AI has made remarkable development in intelligence-driven modernization of TCM tongue diagnosis, pulse diagnosis, listening and smelling diagnosis and text processing, and there are useful explorations in the field of constructing data-driven TCM diagnostic model and multidisciplinary integration of TCM diagnostic models. However, the current integration of AI technology in TCM diagnosis still faces many challenges, such as the scarcity and uneven quality of clinical data, the limited ability of AI algorithms to express TCM thinking model of syndrome differentiation and empirical knowledge, and the possible existence of ethical and privacy issues. By systematically sorting out the current research status and development direction of AI-empowered TCM diagnostics, it is proposed to promote the application of AI technology in TCM diagnostics in four aspects, namely, strengthening the construction of TCM big data and talent cultivation, encouraging cross-disciplinary cooperation, improving the legal and ethical framework, and promoting the popularity of the technology in primary care, so as to enhance the modernisation of TCM diagnostics.

A high-performance liquid chromatography method using pre-column derivatization with 6-aminoquinolyl-N-hydroxysuccinimidyl carbamate was developed to determine the content of 15 amino acids in the medicinal snakes Bungarus Parvus, Agkistrodon, and Zaocys. The results showed that the total amino acid(TAA) content ranged from 277.13 to 515.05 mg·g~(-1), with the top four amino acids in all three species being glutamic acid(Glu), glycine(Gly), aspartic acid(Asp), and lysine(Lys). The essential amino acid(EAA) content ranged from 74.56 to 203.94 mg·g~(-1), with Agkistrodon exhibiting the highest content. The non-essential amino acid(NEAA), semi-essential amino acid(semi-EAA), and medicinal amino acid(MAA) content ranged from 189.06 to 318.23, 12.89 to 33.53, and 179.83 to 342.33 mg·g~(-1), respectively, with Zaocys having the highest content in these categories. Amino acid nutritional value was evaluated using the amino acid ratio(RAA), amino acid ratio coefficient(RCAA), and amino acid ratio coefficient score(SRCAA), and the results indicated that all three medicinal snakes possessed good nutritional value. The amino acid composition was similar across the species, though significant differences in content were observed. Based on these differences, an orthogonal partial least squares-discriminant analysis(OPLS-DA) model was established, which could clearly distinguish between the three medicinal snake species. The key differences in amino acid content included Gly, tyrosine(Tyr), Glu, and serine(Ser), which may be related to the observed clinical application differences among the species. Further research into the mechanisms of these differential amino acids is expected to provide more insights into the clinical application disparities of these three medicinal snake species.

Baihuasheshecao(Hedyotis diffusa) is a commonly used traditional Chinese medicine derived from the whole herb of H. diffusa and has been widely utilized in folk medicine. It possesses anti-tumor, antibacterial, and anti-inflammatory properties, making it one of the frequently used herbs in TCM clinical practice. However, Shuixiancao(H. corymbosa) and Xianhuaercao(H. tenelliflora), species of the same genus, are often used as substitutes for Baihuasheshecao. To substantiate the medicinal basis of Baihuasheshecao, this study systematically reviewed classical herbal texts and modern literature, examining its nomenclature, botanical origin, harvesting, processing, properties, meridian tropism, pharmacological effects, and clinical applications. The results indicate that Baihuasheshecao was initially recorded as "Shuixiancao" in Preface to the Indexes to the Great Chinese Botany(Zhi Wu Ming Shi Tu Kao). Based on its morphological characteristics and habitat description, it was identified as H. diffusa in the Rubiaceae family. Subsequent records predominantly refer to it as Baihuasheshecao as its official name. In most regions, Baihuasheshecao is recognized as the authentic medicinal material, distinct from Shuixiancao and Xianhuaercao. Baihuasheshecao is harvested in late summer and early autumn, and the dried whole plant, including its roots, is used medicinally. The standard processing method involves cutting. It is known for its effects in clearing heat, removing toxins, reducing swelling and pain, and promoting diuresis to resolve abscesses. Initially, it was mainly used for treating appendicitis, intestinal abscesses, and venomous snake bites, and later, it became a treatment for cancer. The excavation of its clinical value followed a process in which overseas Chinese introduced the herb from Chinese folk medicine to other countries. After its unique anti-cancer effects were recognized abroad, it was reintroduced to China and gradually became a crucial TCM for cancer treatment. The findings of this study help clarify the historical and contemporary uses of Baihuasheshecao, providing literature support and a scientific basis for its rational development and precise clinical application.

The gradient field, one of the core magnetic fields in magnetic resonance imaging (MRI) systems, is generated by gradient coils and plays a critical role in spatial encoding and the generation of echo signals. The uniformity or linearity of the gradient field directly impacts the quality and distortion level of MRI images. However, traditional point measurement methods lack accuracy in assessing the linearity of gradient fields, making it difficult to provide effective parameters for image distortion correction. This paper introduced a spherical measurement-based method that involved measuring the magnetic field distribution on a sphere, followed by detailed magnetic field calculations and linearity analysis. This study, applied to assess the nonlinearity of asymmetric head gradient coils, demonstrated more comprehensive and precise results compared to point measurement methods. This advancement not only strengthens the scientific basis for the design of gradient coils but also provides more reliable parameters and methods for the accurate correction of MRI image distortions.

Cemental tear is a rare and indetectable condition unless obvious clinical signs present with the involvement of surrounding periodontal and periapical tissues. Due to its clinical manifestations similar to common dental issues, such as vertical root fracture, primary endodontic diseases, and periodontal diseases, as well as the low awareness of cemental tear for clinicians, misdiagnosis often occurs. The critical principle for cemental tear treatment is to remove torn fragments, and overlooking fragments leads to futile therapy, which could deteriorate the conditions of the affected teeth. Therefore, accurate diagnosis and subsequent appropriate interventions are vital for managing cemental tear. Novel diagnostic tools, including cone-beam computed tomography (CBCT), microscopes, and enamel matrix derivatives, have improved early detection and management, enhancing tooth retention. The implementation of standardized diagnostic criteria and treatment protocols, combined with improved clinical awareness among dental professionals, serves to mitigate risks of diagnostic errors and suboptimal therapeutic interventions. This expert consensus reviewed the epidemiology, pathogenesis, potential predisposing factors, clinical manifestations, diagnosis, differential diagnosis, treatment, and prognosis of cemental tear, aiming to provide a clinical guideline and facilitate clinicians to have a better understanding of cemental tear.
