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.

Objective:To explore the influencing factors of fetal growth restriction (FGR) in patients with preeclampsia (PE) and construct a Nomogram prediction model.Methods:From Aug. 2021 to May. 2023, 273 PE patients admitted to our hospital were regarded as the study subjects, and grouped into a modeling group (n=191) and a validation group (n=82). Multivariate logistic regression analysis was applied to determine the influencing factors of FGR in PE patients. R4.3.1 was applied to construct a Nomogram model for predicting FGR in PE patients. Receiver operating characteristic (ROC) curve and the Hosmer Lemeshoe (H-L) goodness of fit test were applied to evaluate the discrimination and consistency of the Nomogram model in predicting FGR in PE patients.Results:There was no statistically obvious difference in gestational age, blood pressure, hemoglobin, urinary protein (UP), uric acid, umbilical artery systolic/diastolic blood pressure (S/D), D-dimer (D-D), or birth frequency between the modeling group and the validation group ( P>0.05). Compared with no concurrent FGR group, the onset of pregnancy in the concurrent FGR group was earlier, the levels of UP, S/D, and D-D, and the proportion of oligohydramnios were obviously higher, and the platelet count (PLT) was obviously lower ( t/χ 2=2.588, 1.437, 6.262, 5.464, 9.881, 3.326, P<0.05). Multivariate Logistic regression analysis showed that UP, S/D, D-D, and oligohydramnios were risk factors for FGR in PE patients ( OR=1.004, 3.807, 1.006, 4.348, P<0.05), while PLT was a protective factor ( OR=0.980, P<0.05). Nomogram model showed that when the total score of the above 5 influencing factors in PE patients was 149, the probability of concurrent FGR was 60%; when the total score was 167, the probability of concurrent FGR was 90%, and the probability of exceeding 167 was over 90%. Modeling group H-L test χ 2=6.736, P=0.565, validation group χ 2=5.812, P=0.668. The area under the ROC curve (AUC) of the modeling group and the validation group was 0.924 (95% CI: 0.883-0.965) and 0.932 (95% CI: 0.880-0.984), respectively. The sensitivity was 83.93% and 90.48%, and the specificity was 89.63% and 81.97%, respectively. Decision curve analysis (DCA) was applied to evaluate the clinical application value of the Nomogram model in predicting FGR in PE patients. Conclusion:The Nomogram model constructed based on the five indicators of UP, S/D, D-D, PLT, and oligohydramnios for predicting the risk of FGR in PE patients has high discrimination and consistency.

Children with short bowel syndrome (SBS) mainly rely on long-term parenteral nutrition to obtain adequate nutrients until the length and function of the small intestine are improved. In recent years, the clinical application of human glucagon-like peptide 2 analogue Teduglutide has made it more likely for SBS patients to discontinue parenteral nutrition as early as possible and achieve intestinal functional autonomy. This paper reports two cases of SBS children who were treated with Teduglutide combined with parenteral and enteral nutrition for intestinal rehabilitation, and finally got rid of parenteral nutrition. According to the author, there have been no reports of pediatric children using Teduglutide in China.

Background/Aims:
The accuracy of endosonographers in diagnosing gastric subepithelial lesions (SELs) using endoscopic ultrasonography (EUS) is influenced by experience and subjectivity. Artificial intelligence (AI) has achieved remarkable development in this field. This study aimed to develop an AI-based EUS diagnostic model for the diagnosis of SELs, and evaluated its efficacy with external validation.
Methods:
We developed the EUS-AI model with ResNeSt50 using EUS images from two hospitals to predict the histopathology of the gastric SELs originating from muscularis propria. The diagnostic performance of the model was also validated using EUS images obtained from four other hospitals.
Results:
A total of 2,057 images from 367 patients (375 SELs) were chosen to build the models, and 914 images from 106 patients (108 SELs) were chosen for external validation. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of the model for differentiating gastrointestinal stromal tumors (GISTs) and non-GISTs in the external validation sets by images were 82.01%, 68.22%, 86.77%, 59.86%, and 78.12%, respectively. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy in the external validation set by tumors were 83.75%, 71.43%, 89.33%, 60.61%, and 80.56%, respectively. The EUS-AI model showed better performance (especially specificity) than some endosonographers.The model helped improve the sensitivity, specificity, and accuracy of certain endosonographers.
Conclusions
We developed an EUS-AI model to classify gastric SELs originating from muscularis propria into GISTs and non-GISTs with good accuracy. The model may help improve the diagnostic performance of endosonographers. Further work is required to develop a multi-modal EUS-AI system.

The aim of the present study was to explore the role of group II and III metabotropic glutamate receptors (mGluRs) in carotid body plasticity induced by chronic intermittent hypoxia (CIH) in rats. Sprague Dawley (SD) rats were treated with CIH in Oxycycler A84 hypoxic chamber for 4 weeks, and the tail artery blood pressure was measured at the end of model preparation. RT-qPCR was performed to examine the mRNA expression levels of mGluR2/3/8 in rat carotid body. Carotid sinus nerve activity was detected by ex vivo carotid sinus nerve discharge recording technique, and acute intermittent hypoxia (AIH) was administered to induce carotid body sensory long-term facilitation (sLTF), in order to observe the role of group II and group III mGluRs in carotid body plasticity induced by CIH. The results showed that: 1) After 4 weeks of CIH exposure, the blood pressure of rats increased significantly; 2) CIH down-regulated the mRNA levels of mGluR2/3, and up-regulated the mRNA level of mGluR8 in the carotid body; 3) AIH induced sLTF in carotid body of CIH group. In the CIH group, activation of group II mGluRs had no effect on sLTF of carotid body, while activation of group III mGluRs completely inhibited sLTF. These results suggest that CIH increases blood pressure in rats, and group III mGluRs play an inhibitory role in CIH-induced carotid body plasticity in rats.

The purpose of the present study was to explore the role of carotid body metabotropic glutamate receptor 1 (mGluR1) in chronic intermittent hypoxia (CIH)-induced carotid body plasticity. Sprague Dawley (SD) rats were exposed to CIH (6%-21% O2, 4 min/cycle, 8 h/day) for 4 weeks. The blood pressure of rats was monitored non-invasively by tail-cuff method under consciousness. RT-qPCR was used to examine the mRNA expression level of mGluR1 in rat carotid body. Western blot was used to detect the protein expression level of mGluR1 in rat carotid body. The role of mGluR1 in CIH-induced carotid body sensory long-term facilitation (sLTF) was investigated by ex vivo carotid sinus nerve discharge recording, and the carotid body sLTF was evoked by a 10-episode of repetitive acute intermittent hypoxia (AIH: 1 min of 5% O2 interspersed with 5 min of 95% O2). The results showed that: 1) CIH increased the systolic blood pressure (P < 0.001), diastolic blood pressure (P < 0.005) and mean arterial blood pressure (P < 0.001) of rats; 2) CIH decreased the mRNA and protein levels of mGluR1 in the rat carotid body (P < 0.01); 3) 4 weeks of CIH induced carotid body sLTF significantly, exhibiting as an increasing baseline sensory activity during post-AIH, which was inhibited by application of an agonist of group I metabotropic glutamate receptors, (S)-3,5-dihydroxyphenylglycine (DHPG), during sLTF induction (P < 0.005). In summary, these results suggest that activation of mGluR1 inhibits CIH-induced carotid body plasticity in rats.

Objective:
To explore the effects and mechanisms of interfering with transient receptor potential melastatin subfamily member 7(TRPM7) on biological behaviors(proliferation, apoptosis, invasion) of laryngeal carcinoma cells.
Methods:
Human laryngeal carcinoma cells TU212 were culturedin vitro. TRPM7-shRNA plasmid vectors(TRPM7-shRNA1 group, TRPM7-shRNA2 group, TRPM7-shRNA3 group) and negative control shRNA-NC(shRNA-NC group) were constructed. TU212 cells were transfected by liposome transfection method. The cells transfected with empty vector were enrolled as Control group. The level of lactic dehydrogenase(LDH) in TU212 supernatant was detected by ELISA. The level of malondialdehyde(MDA) and activity of superoxide dismutase(SOD) in supernatant were detected by colorimetry. The effects of knocking-down TRPM7 on proliferation and invasion of TU212 cells were detected by CCK-8, clone formation assay and Transwell assay. The expressions of invasion and apoptosis-related proteins were detected by Western blot.
Results:
After transfection, expression levels of TRPM7 mRNA and protein were down-regulated in TRPM7-shRNA1 group, TRPM7-shRNA2 group and TRPM7-shRNA3 group compared with Control group(P<0.05), and the decrease was the most significant in TRPM7-shRNA1 group(P<0.05). In functional experiments, SOD level in TRPM7-shRNA1 group decreased compared with Control group(P<0.05), while MDA and LDH levels increased(P<0.05). The cells proliferation rate and clone formation rate were decreased(P<0.05), the number of invasion cells was reduced(P<0.05), the expressions of N-cadherin and Vimentin proteins were down-regulated(P<0.05), mitochondrial membrane potentials were reduced(P<0.05), Bax/Bcl-2 and cleaved caspase-3/caspase-3 increased(P<0.05).
Conclusion
Knocking-down TRPM7 can increase oxidative stress level in laryngeal carcinoma cells TU212, inhibit their proliferation and invasion, and induce their apoptosis by mitochondrial pathways.
