Ankylosing spondylitis is a chronic immunoinflammatory disease that mainly affects the spine and the sacroiliac joint， the mechanism of which is closely related to signaling pathways， such as osteoprotegerin （OPG）/receptor activator of nuclear factor-κB （RANK）/RANK ligand， mitogen-activated protein kinase （MAPK）， Wnt/β-catenin （β-catenin）， phosphoinositide 3- kinase/protein kinase B/mammalian target of rapamycin （PI3K/Akt/mTOR）. Traditional Chinese medicine has the characteristics of multiple components and targets， and is widely used for the treatment of autoimmune diseases due to its low toxicity， strong specificity， and high efficacy. This review found that monomers and compounds of traditional Chinese medicine can exert anti ankylosing spondylitis effects by intervening in the aforementioned signaling pathways， regulating immune inflammatory responses， and inhibiting biological processes such as bone destruction， ectopic osteogenic differentiation， cell apoptosis， and autophagy.

BACKGROUND:The Yi people have used Sambucus adnata Wall to treat fractures,bruises,arthritis,etc.The author's group found that the active site aqueous extract(SAW-A)and dichloromethane extract(SAW-B)can promote fracture healing by promoting the expression of genes related to osteoblast proliferation,differentiation and maturation,differentiation and maturation.However,the therapeutic effect of methanol extract(SAW-C)at its active site on osteoarthritis is unclear. OBJECTIVE:To investigate the therapeutic effect of Sambucus adnata Wall extract on osteoarthritis,and to identify the effective targets of Sambucus adnata Wall extract in the treatment of osteoarthritis by network pharmacology technology. METHODS:A rat osteoarthritis model was replicated by anterior cruciate ligamentectomy and model rats were then treated with methanol extract of Sambucus adnata Wall by gavage for 21 days.On the 21st day after modeling,the knee joint of rats was detected by X-ray,the width of the knee joint was measured,oxidative stress indexes and inflammatory factors levels in serum and joint lavage fluid were detected,the morphology of the knee joint was observed by hematoxylin-eosin staining,full-thickness cartilage and hyaline cartilage thickness were measured,and the content of articular cartilage proteoglycan was observed by safranin O-fast green staining.The"drug-component-disease-target"network was constructed.Gene ontology enrichment analysis and Kyoto encyclopedia of genes and genomes enrichment analysis of effective targets were performed,and protein-protein interaction network maps were constructed using cytoscape software. RESULTS AND CONCLUSION:Sambucus adnata Wall extract could reduce tumor necrosis factor-α level in joint lavage fluid and serum levels of prostaglandin E2 and malondialdehyde,while increase the level of superoxide dismutase;relieve joint swelling caused by osteoarthritis;improve the histopathological state of articular cartilage,maintain the thickness of full-thickness articular cartilage,hyaline cartilage and the area of bone trabeculae in subchondral bone;and effectively prevent the loss of proteoglycans in articular cartilage and have a chondroprotective effect.Network pharmacological results showed that the methanol extract of Sambucus adnata Wall may have some targets related to inhibition of tumor necrosis factor,AKT1,interleukin-6,MAPK3,and SRC as well as inhibition of over-activation of EGFR signaling pathway and AGE-RAGE signaling pathway.

OBJECTIVE: To develop a noninvasive method for prediction of 1p/19q codeletion in diffuse lower-grade glioma (DLGG) based on multimodal magnetic resonance imaging (MRI) radiomics. METHODS: We collected MRI data from 104 patients with pathologically confirmed DLGG between October, 2015 and September, 2022. A total of 535 radiomics features were extracted from T₂WI, T₁WI, FLAIR, CE-T₁WI and DWI, including 70 morphological features, 90 first order features, and 375 texture features. We constructed logistic regression (LR), logistic regression least absolute shrinkage and selection operator (LRlasso), support vector machine (SVM) and Linear Discriminant Analysis (LDA) radiomics models and compared their predictive performance after 10-fold cross validation. The MRI images were reviewed by two radiologists independently for predicting the 1p/19q status. Receiver operating characteristic curves were used to evaluate classification performance of the radiomics models and the radiologists. RESULTS: The 4 radiomics models (LR, LRlasso, SVM and LDA) achieved similar area under the curve (AUC) in the validation dataset (0.833, 0.819, 0.824 and 0.819, respectively; P>0.1), and their predictive performance was all superior to that of resident physicians of radiology (AUC=0.645, P=0.011, 0.022, 0.016, 0.030, respectively) and similar to that of attending physicians of radiology (AUC=0.838, P>0.05). CONCLUSION Multiparametric MRI radiomics models show good performance for noninvasive prediction of 1p/19q codeletion status in patients with in diffuse lower-grade glioma.

Objective:To evaluate the performance of Autoderm, an artificial intelligence application, in the diagnosis of skin diseases in Chinese patients.Methods:Totally, 920 patients with confirmed skin diseases were prospectively recruited in the Department of Dermatology, the First Affiliated Hospital of Zhengzhou University. Every patient provided 1 clinical image, which was uploaded onto the Autoderm application for the diagnosis of skin diseases. The diagnostic sensitivity, specificity and accuracy of the Autoderm application were estimated, and the kappa values for the diagnostic agreement between the Autoderm application and dermatologists were calculated.Results:Among the 920 patients, 871 (94.7%) could be diagnosed with an Autoderm′s in-distribution skin disease, whereas 49 (5.3%) had out-of-distribution skin diseases. According to the top 1 and 3 diagnoses given by the Autoderm application for the 920 patients separately, its mean diagnostic sensitivities were 41.8% and 65.8%, mean specificities 96.8% and 91.5%, and mean accuracies 92.9% and 89.9%, respectively, and there was moderate overall agreement between the Autoderm application and dermatologists (κ = 0.420, 0.464, respectively). However, for an out-of-distribution skin disease, the Autoderm application could output 5 definitely false diagnoses.Conclusion:Autoderm may be used as as clinical decision support tool for the diagnosis of common skin diseases in most Chinese patients, with moderate diagnostic sensitivity, high specificity, and high accuracy, but misdiagnosis may occur.

Ossifying fibroma (OF) and fibrous dysplasia (FD) are two fibro-osseous lesions with overlapping clinicopathological features, making diagnosis challenging. In this study, we applied a whole-genome shallow sequencing approach to facilitate differential diagnosis via precise profiling of copy number alterations (CNAs) using minute amounts of DNA extracted from morphologically correlated microdissected tissue samples. Freshly frozen tissue specimens from OF (n = 29) and FD (n = 28) patients were obtained for analysis. Lesion fibrous tissues and surrounding normal tissues were obtained by laser capture microdissection (LCM), with ~30-50 cells (5 000-10 000 µm

Objective: To understand the possible transmission route of a family cluster of COVID-19 in Zhengzhou and the potential infectivity of COVID-19 in incubation period, and provide scientific evidence for the timely control of infectious source and curb the spread of the epidemic. Methods: Epidemiological investigation was conducted for a family cluster of COVID-19 (8 cases) with descriptive epidemiological method, and respiratory tract samples of the cases were collected for the nucleic acid detection of 2019-nCoV by RT-PCR. Results: Two primary cases, which occurred on 31 January and 1 February, 2020, respectively, had a common exposure history in Wuhan. The other six family members had onsets on 30 January, 31 January, 1 February (three cases) and 3 February, 2020. Conclusions In this family cluster of COVID-19, six family members were infected through common family exposure to the 2 primary cases. Five secondary cases had onsets earlier than or on the same day as the primary cases, indicating that COVID-19 is contagious in incubation period, and the home isolation in the early phase of the epidemic might lead to the risk of family cluster of COVID-19.

OBJECTIVE: To investigate the genetic characterization of 3-hydroxyisovalerylcarnitine (C5-OH) metabolic abnormality in neonates. METHODS: Fifty two newborns with increased C5-OH, C5-OH/C3 and C5-OH/C8 detected by tandem mass spectrometry during neonatal screening were enrolled in the study. Genomic DNA was extracted from the whole blood samples of 52 cases and their parents. Seventy-nine genes associated with genetic and metabolic diseases including , were targeted by liquid capture technique. Variation information of these genes was examined by high-throughput sequencing and bioinformatic analysis, and then was classified based on the American College of Medical Genetics and Genomics (ACMG) standards and guidelines. The genetic types were classified as wild-type, -maternal-mutation, -paternal-mutation and -mutation. Wilcoxon rank-sum test was performed for the increased multiples of C5-OH calculated in neonatal screening. RESULTS: Twenty one variants (14 novel) were identified in 37 cases, 6 variants (5 novel) in 4 cases. The increased multiple of C5-OH calculated in -maternal-mutation and -mutation groups were significantly higher than that in wild-type group (all <0.05), while there was no significant difference between MCCC1-paternal-mutation group and wild-type group (>0.05). CONCLUSIONS Mutations on and genes are the major genetic causes for the increased C5-OH in neonates, and maternal single heterozygous mutation can contribute to the moderately to severely increased C5-OH.

To review the development history of the experimental animal acupoints. To analyze different historical periods, the names of animal acupoints, positioningmethods and references, it is believed that the understanding of experimental animal acupoints has gone through four stages, including initiation, accumulation, specification and standards. At the same time, some important events in the development of experimental animal acupoints were sorted out, including the publication of key papers, books, teaching materials, and the convening of important conferences. In addition, the significance of the above stages of development and the relationship between them were also analyzed to provide basic clues and evidence for the rational understanding of the characteristics and laws of experimental animals. It is concluded that the development of experimental animal acupoints has evolved from simple to complex, from fuzzy to precise.
