ObjectiveTaking Aurantii Fructus Immaturus juice（AFI）-processed Atractylodis Macrocephalae Rhizoma（AMR） as an example， this study aims to systematically compare the volatile and non-volatile components of AMR and its processed products， investigate the key differential components， evaluate their anti-inflammatory activities， and elucidate the synergistic mechanism of processing. MethodsThe chemical compositions of volatile and non-volatile components in AMR and AFI-processed AMR were systematically characterized using gas chromatography-mass spectrometry（GC-MS） and ultra-performance liquid chromatography-quadrupole-time-of-flight mass spectrometry（UPLC-Q-TOF-MS）， with relative mass fractions and response values determined separately. Volatile components were identified through searches in the National Institute of Standards and Technology（NIST）17 database， comparison with retention index（RI） and fragmentation pattern matching. Non-volatile components were identified by searching Waters Traditional Chinese Medicine （TCM） spectral library， in conjunction with PubChem and MassBank， characteristic fragmentation patterns and response values were also used to support identification. Differential components were screened using principal component analysis（PCA）， orthogonal partial least squares-discriminant analysis（OPLS-DA）， with variable importance in the projection（VIP） value >1. Components with high log₂fold change（FC） among major differential groups were selected as those exhibiting significant changes before and after processing. The anti-inflammatory activity of the differential compounds was evaluated by assessing their effects on nitric oxide（NO） production in a lipopolysaccharide（LPS）-induced RAW264.7 macrophage model. Enzyme-linked immunosorbent assay（ELISA） was used to detect the effects of the differential components on tumor necrosis factor（TNF）-α， interleukin（IL）-1β， IL-6， and monocyte chemotactic protein（MCP）-1 levels， and immunofluorescence（IF） was employed to assess their effects on nuclear transcription factor（NF）-κB p65 translocation， thereby elucidating the underlying molecular mechanisms. ResultsA total of 36 compounds were identified in the volatile components of AMR and AFI-processed AMR， among which， sesquiterpenes and monoterpenes were significantly increased after processing. In the non-volatile components， 36 compounds were identified， and the main differential components were flavonoids， sesquiterpenoids， and triterpenoids. Flavonoids were the primary differential components distinguishing AMR from its processed products， representing compounds directly introduced during processing. Five compounds， including atractylenolide Ⅲ， tangeritin， nobiletin， hesperidin and narirutin， were selected as representatives of three classes based on their most prominent differential expression among different compound types for subsequent anti-inflammatory activity studies. The results showed that 100 μmol·L^-1 tangerine and narirutin could significantly inhibit LPS-induced NO production（P<0.01） in a concentration-dependent manner. Tangeritin was able to significantly inhibit the levels of TNF-α and MCP-1 secreted by RAW264.7（P<0.05）， while narirutin significantly inhibited the levels of TNF-α， IL-1β， MCP-1 and IL-6（P<0.01）. IF revealed that both tangeritin and narirutin significantly blocked the translocation of NF-κB p65 from the cytoplasm to the nucleus. ConclusionAFI-processed AMR significantly alters the chemical composition profile of AMR， and the newly introduced flavonoid components during processing may be key to its enhanced anti-inflammatory effects.

OBJECTIVE: To establish a similarity measurement model for patients with dentofacial deformity based on 3D craniofacial features and to validate the similarity results with quantifying subjective expert scoring. METHODS: In the study, 52 cases of patients with skeletal Class Ⅲ malocclusions who underwent bimaxillary surgery and preoperative orthodontic treatment at Peking University School and Hospital of Stomatology from January 2020 to December 2022, including 26 males and 26 females, were selected and divided into 2 groups by sex. One patient in each group was randomly selected as a reference sample, and the others were set as test samples. Three senior surgeons rated the similarity scores between the test samples and the reference sample. Similarity scores ranged from 1 to 10, where 1 was completely different, and 10 was exactly the same. Scores larger than 7.5 was considered as clinically similar. Preoperative cone beam computed tomography (CBCT) and 3D facial images of the patients were collected. The three-dimensional hard and soft tissue features, including distances, angles and 3D point cloud features were extracted. The similarity measurement model was then established to fit with the experts' similarity scoring by feature selection algorithm and linear regression model. To verify the reliability of the model, 14 new patients were selected and input to similarity measurement model for finding similar cases. The similarity scoring of these similar cases were rated by experts, and used to evaluate the reliability of the model. RESULTS: The similarity metric models indicated that the features of the middle and lower craniofacial features were the main features to influence the craniofacial similarity. The main features that were related to the expert' s similarity scoring included distance of anterior nasal spine-menton (ANS-Me), distance of right upper canion point-Frankfurt horizontal plane (U3RH), distance of left superior point of the condyle-left gonion (CoL-GoL), distance of left gonion-menton (CoL-Me), distance of pogonion-midsagittal plane (Pog-MSP), distance of right alar base-left alar base (AlR-AlL), angle of pronasale-soft tissue pogonion-labrale inferius (Pn-Pog' -Li), distance of trichion-right tragus (Tri-TraR), distance of left exocanthion-left alar base (ExL-AlL), lower 1/3 of skeletal face, middle and lower 2/3 of skeletal face and upper lip region of soft tissue. Fourteen new patients were chosen to evaluate the model. The similar cases selected by the model had an average experts' similarity scoring of 7.627± 0.711, which was not significantly different with 7.5. CONCLUSION The similarity measurement model established by this model could find the similar cases which highly matched experts' subjective similarity scoring. The study could be further used for similar cases retrieval in skeletal Ⅲ malocclusion patients.

Macrophages are closely related to tumor progression,and can promote tumor growth and pro-liferation by promoting inflammation,angiogenesis and immunosuppression and so on,as well as killing tumors by directly killing tumor cells and triggering specific immune responses.Iron death,as an iron-depend-ent cell death caused by lipid peroxidation,can effectively kill tumor cells when regulated from the perspective of iron homeostasis,and can also release pro-inflammatory factors,trigger inflammatory reactions,change the survival environment of tumors as well as reduce the immune susceptibility of tumor cells.In recent years,more and more studies have shown that macrophages and iron death are closely related.In this paper,the rela-tionship between macrophages and iron death in terms of their functional properties and targeting of tumors are mainly introduced,and an overview of the functional properties of the two differentiated phenotypes of macrophages for the treatment of iron death in tumors is provided.

Objective:To explore the efficacy and safety of endoscopic radial incision (ERI) for congenital membranous duodenal stenosis (MDS).Methods:The clinical data of 13 children with MDS receiving ERI in the Department of Gastroenterology of Xi'an Children's Hospital from May 2017 to December 2021 were reviewed and analyzed. The perioperative management, surgical procedures, postoperative complications and follow-up were summarized.Results:There were 5 boys and 8 girls with a median disease duration of 8 (2-20) months, and the median age of diagnosis was 13 months (5-30 months). The septum of 10 cases (10/13) was located in the descending part of the duodenum, and that of 3 cases (3/13) in the horizontal part. The papilla of 1 case (1/13) opened on the septum, that of 3 cases (3/13) within 5 cm of the mouth side of the septum, and that of 9 cases (9/13) within 5 cm of the anal side of the septum. The median diameter of the septal aperture was 3 mm (2-6 mm). All 13 children successfully underwent ERI with a median operation time of 20 min (15-32 min). The average surgical incision was 3 strokes (2-4 strokes), and the endoscope with outer diameter 9.9 mm could pass stenosis after ERI. The median incision diameter was 10 mm (10-12 mm). All patients achieved relief of clinical symptoms after ERI. One patient (1/13) suffered from the postoperative delayed bleeding, which was stopped by endoscopic titanium clamping. No intestinal perforation or duodenal papilla injury occurred, and median postoperative hospital stay was 6 days (5-10 days). The upper gastrointestinal angiogram and gastroscopy were repeated 3 months after ERI, and the median diameter of stenosis was 12 mm (10-15 mm), which was significantly dilated compared with before. The mean body weight increase at 1 month after ERI was 1.20 kg (0.50-1.80 kg), and the mean body weight increase at 3 months was 3.50 kg (2.50-4.00 kg), which reached the normal body weight of the same age.Conclusion:ERI is safe and effective for the treatment of MDS in children, and shows good clinical application and promotion value.

Objective To explore the association between mammalian sterile 20-like kinase 1(MST1)gene poly-morphism and haplotype and the risk of colorectal cancer,rectal cancer,and colon cancer in the Han population in Baotou area by case-control association study.Methods A total of 390 patients with colorectal cancer diagnosed by pathology and 413 normal physical examination population were collected,and 2 ml of peripheral blood was taken for subsequent gene genotyping.Single nucleotide polymorphisms(SNPs)of MST1 gene were screened according to the genetic polymorphism data of Chinese Han population provided by the National Center for Biotechnology In-formation-Haplotype Mapping database.Gene genotyping was performed by Taqman method.Logistic regression was used to calculate the association between each SNP and the risk of colorectal cancer,colon cancer,and rectal cancer under codominant,dominant,overdominant,and recessive genetic models.Results Four SNPs of MST1 gene were screened,namely rs8000,rs2234197,rs2267853,and rs6073629.Among them,SNP rs2234197 was associated with the risk of rectal cancer.Compared with the GG+AA genotype,the AG genotype could reduce the risk of rectal cancer,OR[95%confidence interval(CI)]=0.657(0.442-0.976).SNP rs8000 was associated with the risk of colon cancer.Compared with the TT+GT genotype,the GG genotype could reduce the risk of colon cancer[OR(95%CI)=0.425(0.182-0.992)].Conclusion MST1 gene SNP rs2234197 AG genotype and SNP rs8000 GG genotype may be protective factors for rectal cancer and colon cancer,respectively.

Objective To investigate the associations of the single nucleotide polymorphism (SNP) rs2304733 in TEA domain transcription factor 1 (TEAD1) , rs7135838 and rs1990330 in TEA domain transcription factor 4 (TEAD4) genes with the risk of non-cardia gastric carcinogenesis.Methods Enzyme linked immunosorbent assay (ELISA) was used to detect specific antibodies against Helicobacter pylori(Hp) in serum samples of the normal con-trol group.470 normal controls were divided into Hp infection negative group (n=223) and positive group (n=247) based on antibody titers.In the 450 non-cardia gastric cancer cases and 470 controls, polymerase chain reac-tion-restriction fragment length polymorphism (PCR-RFLP) was used to genotype the each SNP locus.The uncon-ditional Logistic regression method was used to evaluate the associations between each SNP locus and the risk of non-cardia gastric carcinogenesis.Results The SNPs of TEAD1 and TEAD4 were not associated with Hp infec-tion.TEAD1 rs2304733 was associated with the risk of non-cardia gastric cancer.Compared with the carriers of TT genotype, the carries of CT and CC genotypes had an increased risk of non-cardia gastric cancer (CT vs TT:OR=2.321 , 95％CI:1.690-3.188;CC vs TT:OR=5.140 , 95％CI:1.080-24.463) .TEAD4 rs1990330 was as-sociated with the risk of non-cardia gastric cancer.Compared with the carriers of GG genotype, those with GT geno-type had an increased risk of non-cardia gastric cancer (OR = 2.405 , 95％ CI: 1.480 - 3.908) .TEAD4 rs7135838 was not associated with the risk of non-cardia gastric cancer.TEAD1 rs2304733, TEAD4 rs7135838 and rs1990330 had interaction effects on the risk of non-cardia gastric cancer (P<0.05).Conclusion In Baotou Han population, TEAD1 rs2304733 and TEAD4 rs1990330 do not play a major role in Hp infection, but may play a role in the risk of non-cardia gastric cancer.TEAD4 rs7135838 may not play a major role in the risk of Hp infec-tion and non-cardia gastric cancer.TEAD1 rs2304733 and TEAD4 rs1990330 have the strongest synergistic effect on the risk of non-cardia gastric cancer, which is the best interaction model.
