ObjectiveTo explore the clinical and phenomics characteristics of patients with phlegm-stasis binding syndrome and its accompanied patterns in stable angina pectoris （SAP） of coronary heart disease （CHD）. MethodsA multicenter cross-sectional study design was adopted. A total of 300 patients with SAP of CHD were enrolled and classified into 120 cases of phlegm-stasis binding syndrome， 125 cases of qi deficiency-accompanied syndrome， 38 cases of qi stagnation-accompanied syndrome， and 17 cases of toxin accumulation-accompanied syndrome according to traditional Chinese medicine （TCM） patterns. Data of patients with different TCM patterns were collected， including general condition， TCM symptoms， blood lipids， coagulation function， immune indicators， and serum metabolomics. Metabolic pathway enrichment analysis was used to compare differences in phenomics characteristics among groups. Metabolites with variable importance in projection （VIP） ≥1 and fold change （FC） ≥2 were considered as representative differential metabolites. ResultsPatients in each TCM pattern type were most commonly in the 60-75 years age group， with a relatively high proportion of males. Regarding TCM symptoms， patients with phlegm-stasis binding syndrome most commonly presented with wiry-choppy or wiry-slippery pulse， chest pain， and chest tightness； in patients with qi deficiency-accompanied syndrome， fatigue， chest pain， and weak pulse were most common； in patients with qi stagnation-accompanied sydnrome， wiry-choppy or wiry-slippery pulse， chest pain， and symptoms that increase or decrease with emotional changes， belching， or flatulence were most common； in patients with toxin accumulation-accompanied syndrome， bitter taste in the mouth， chest tightness， irritability， restlessness or manic delirium， and dry and hard stools or foul-smelling diarrhea were most common. Comparisons among the different TCM patterns showed statistically significant differences in coagulation parameters （P＜0.05）， whereas no statistically significant difference was found in blood lipid levels and immune indicators （P＞0.05）.Metabolomics analysis suggested that disorders of glycerophosphate metabolism and valine， leucine， and isoleucine metabolism are characteristic features of phlegm-stasis binding syndrome and its accompanied patterns. The representative differential metabolites between phlegm-stasis binding syndrome and qi deficiency-accompanied syndrome were 7,8-dihydrobiopterin （FC = 3.58） and oxypurinol （FC = 124.50）. Those between phlegm-stasis binding syndrome and qi stagnation-accompanied syndrome were cytidine 5′-diphosphocholine （FC = 2.62） and D-mannosamine （FC = 2.99）. Those between phlegm-stasis binding syndrome and toxin accumulation-accompanied syndrome were anserine （FC = 7.83） and canrenone （FC = 8.94）. ConclusionThere are certain differences in the clinical characteristics and phenomics characteristics among patients with SAP due to CHD exhibiting phlegm-stasis binding syndrome and its accompanied patterns. The phenomics characteristics mainly involve biological alterations such as lipid metabolism disorders， amino acid metabolism abnormalities， and multiple immune indicators activation， which may provide a reference for precise differentiation and treatment of SAP of CHD in TCM clinical practice.

In order to investigate whether the effect of Yuxuebi Tablets on the peripheral and central inflammation resolution of mice with inflammatory pain is related to their regulation of G protein-coupled receptor 37(GPR37), an inflammatory pain model was established by injecting complete Freund's adjuvant(CFA) into the paws of mice, with a sham-operated group receiving a similar volume of normal saline. The mice were assigned randomly to the sham-operated group, model group, ibuprofen group(91 mg·kg~(-1)), and low-, medium-, and high-dose groups of Yuxuebi Tablets(60, 120, and 240 mg·kg~(-1)). The drug was administered orally from days 1 to 19 after modeling. Von Frey method and the hot plate test were used to detect mechanical pain thresholds and heat hyperalgesia. The levels of interleukin-10(IL-10) and transforming growth factor-beta(TGF-β) in the spinal cord were quantified using enzyme-linked immunosorbent assay(ELISA), and the mRNA and protein expression of GPR37 in the spinal cord was measured by real-time quantitative reverse transcription PCR(qRT-PCR) and Western blot. Additionally, immunofluorescence was used to detect the expression of macrosialin antigen(CD68), mannose receptor(MRC1 or CD206), and GPR37 in dorsal root ganglia, as well as the expression of calcium-binding adapter molecule 1(IBA1), CD206, and GPR37 in the dorsal horn of the spinal cord. The results showed that compared with those of the sham-operated group, the mechanical pain thresholds and hot withdrawal latency of the model group significantly declined, and the expression of CD68 in the dorsal root ganglia and the expression of IBA1 in the dorsal horn of the spinal cord significantly increased. The expression of CD206 and GPR37 significantly decreased in the dorsal root ganglion and dorsal horn of the spinal cord, and IL-10 and TGF-β levels in the spinal cord were significantly decreased. Compared with those of the model group, the mechanical pain thresholds and hot withdrawal latency of the high-dose group of Yuxuebi Tablets significantly increased, and the expression of CD68 in the dorsal root ganglion and IBA1 in the dorsal horn of the spinal cord significantly decreased. The expression of CD206 and GPR37 in the dorsal root ganglion and dorsal horn of the spinal cord significantly increased, as well as IL-10 and TGF-β levels in the spinal cord. These findings indicated that Yuxuebi Tablets may reduce macrophage(microglial) infiltration and foster M2 macrophage polarization by enhancing GPR37 expression in the dorsal root ganglia and dorsal horn of the spinal cord of CFA-induced mice, so as to improve IL-10 and TGF-β levels, promote resolution of both peripheral and central inflammation, and play analgesic effects.

This study aimed to compare the ameliorative effects of Lycii Fructus and Chrysanthemi Flos at different ratios on retinal damage in mice and to elucidate the underlying mechanisms. A retinal injury model was established by intraperitoneal injection of sodium iodate(NaIO_3) solution. The mice were divided into the following groups: blank group, model group, positive drug(AREDS 2) group, low-and high-dose groups of Lycii Fructus and Chrysanthemi Flos at 1∶1, low-and high-dose groups at 3∶1, and low-and high-dose groups at 1∶3. Administration was carried out 15 days after modeling. The visual acuity of the mice was assessed using the black-and-white box test. The fundus was observed using an optical coherence tomography device, and retinal thickness was measured. HE staining was used to observe the morphology and pathological changes of the retina. The levels of oxidative factors in serum and ocular tissues were measured using assay kits. The levels of inflammatory factors in serum and ocular tissues were detected by enzyme-linked immunosorbent assay(ELISA), and the expression of Nrf2, HO-1, and NF-κB proteins in ocular tissues was analyzed by Western blot. The results showed that after administration of Lycii Fructus and Chrysanthemi Flos at different ratios, the model group showed improved retinal thinning and disordered arrangement of retinal layers, elevated content of SOD and GSH in the serum and ocular tissues, and reduced levels of MDA, TNF-α, IL-1β, and IL-6. Lycii Fructus and Chrysanthemi Flos at 1∶1 and 1∶3 showed better improvement effects. The combination significantly upregulated the expression levels of Nrf2 and HO-1 and downregulated the expression of NF-κB p65. These results indicate that Lycii Fructus and Chrysanthemi Flos at different ratios can improve retinal damage, reduce oxidative stress, and alleviate inflammation in both the body and ocular tissues of mice. The mechanism may be related to the regulation of the Nrf2/HO-1 and NF-κB signaling pathways in ocular tissues. These findings provide a theoretical basis for the clinical application of Lycii Fructus and Chrysanthemi Flos in the treatment of dry age-related macular degeneration.

PURPOSE: Intertrochanteric fracture (ITF) classification is crucial for surgical decision-making. However, orthopedic trauma surgeons have shown lower accuracy in ITF classification than expected. The objective of this study was to utilize an artificial intelligence (AI) method to improve the accuracy of ITF classification. METHODS: We trained a network called YOLOX-SwinT, which is based on the You Only Look Once X (YOLOX) object detection network with Swin Transformer (SwinT) as the backbone architecture, using 762 radiographic ITF examinations as the training set. Subsequently, we recruited 5 senior orthopedic trauma surgeons (SOTS) and 5 junior orthopedic trauma surgeons (JOTS) to classify the 85 original images in the test set, as well as the images with the prediction results of the network model in sequence. Statistical analysis was performed using the SPSS 20.0 (IBM Corp., Armonk, NY, USA) to compare the differences among the SOTS, JOTS, SOTS + AI, JOTS + AI, SOTS + JOTS, and SOTS + JOTS + AI groups. All images were classified according to the AO/OTA 2018 classification system by 2 experienced trauma surgeons and verified by another expert in this field. Based on the actual clinical needs, after discussion, we integrated 8 subgroups into 5 new subgroups, and the dataset was divided into training, validation, and test sets by the ratio of 8:1:1. RESULTS: The mean average precision at the intersection over union (IoU) of 0.5 (mAP50) for subgroup detection reached 90.29%. The classification accuracy values of SOTS, JOTS, SOTS + AI, and JOTS + AI groups were 56.24% ± 4.02%, 35.29% ± 18.07%, 79.53% ± 7.14%, and 71.53% ± 5.22%, respectively. The paired t-test results showed that the difference between the SOTS and SOTS + AI groups was statistically significant, as well as the difference between the JOTS and JOTS + AI groups, and the SOTS + JOTS and SOTS + JOTS + AI groups. Moreover, the difference between the SOTS + JOTS and SOTS + JOTS + AI groups in each subgroup was statistically significant, with all p < 0.05. The independent samples t-test results showed that the difference between the SOTS and JOTS groups was statistically significant, while the difference between the SOTS + AI and JOTS + AI groups was not statistically significant. With the assistance of AI, the subgroup classification accuracy of both SOTS and JOTS was significantly improved, and JOTS achieved the same level as SOTS. CONCLUSION In conclusion, the YOLOX-SwinT network algorithm enhances the accuracy of AO/OTA subgroups classification of ITF by orthopedic trauma surgeons.

AIM To explore the clinical effects of Jinfukang Oral Liquid combined with thymosin α1 on patients with non-small cell lung cancer due to Dual Deficiency of Qi and Yin.METHODS Seventy-five patients were randomly assigned into thymosin α1 group(15 cases)for 4-week administration,Jinfukang Oral Liquid group(30 cases)for 4-week administration,and combination group(30 cases)for 4-week administration.The changes in TCM clinical syndrome effects,immunity indices(CD3+T,Th,CTL,total NK,CD56dim CD16+NK,NKT,Treg,MDSC),lethality/inhibition ratios(CTL/Treg,total NK/Treg,NKT/Treg,CTL/MDSC,total NK/MDSC,NKT/MDSC)and FACT-L scores were detected.RESULTS The Jinfukang Oral Liquid group and combination group demonstrated higher total effective rates than the thymosin α1 group(P＜0.05).After the treatment,the Jinfukang Oral Liquid group and combination group displayed increased NKT(P＜0.05)and decreased MDSC(P＜0.05),which were more obvious than those in the thymosin α1 group(P＜0.05),and higher NKT was observable in the Jinfukang Oral Liquid group(P＜0.05);the Jinfukang Oral Liquid group and combination group displayed increased lethality/inhibition ratios(P＜0.05),among which NKT/Treg,CTL/MDSC,total NK/MDSC,NKT/MDSC were higher than those in the thymosin α1 group(P＜0.05),and higher CTL/MDSC,NKT/MDSC were observable in the Jinfukang Oral Liquid group(P＜0.05);the Jinfukang Oral Liquid group(except for physiological status,society and family status)and combination group(except for society and family status)displayed increased FACT-L scores(P＜0.05).CONCLUSION For the patients with non-small cell lung cancer due to Dual Deficiency of Qi and Yin,Jinfukang Oral Liquid single use or combined with thymosin α1 can enhance peripheral blood immune surveillance,inhibit immune escape,restore the balanced state of tumor immune responses,and improve TCM syndromes and life quality.

Trichinella spiralis zinc metalloproteinase NAS-36 gene(TsNas36)is a member of the zinc metalloproteinase family found in excretory secretory products(ESP)of T.spiralis.In this study,TsNas36 gene was cloned and expressed,and its biological characteristics and temporal and spatial characteristics were identified.These results provide a theoretical and material basis for ex-ploring the biological function of TsNas36 gene.Bioinformatics analysis showed that TsNas36 was 470 amino acids(AA)in length with a molecular weight of about 54.69 kDa,no transmembrane region,and contained a signal peptide(1-20 AA),an Astacins domain(116-320 AA)and a CUB domain(355-470 AA).There were five active site residues located at amino acids 216(His),217(Glu),220(His),226(His)and 275(Tyr).The expression plasmid pET-28a(+)/TsNas36 was constructed and induced to express in E.coli BL21(DE3)to obtain the recombinant protein rTs-Nas36.The recombinant protein was used to immunize rabbits to obtain anti-rTsNas36 polyclonal antibody serum.Indirect ELISA results showed that the antibody titer reached 1∶105.qRT-PCR and Western blot results showed that the transcription levels of TsNas36 were significantly higher in newborn larvae(NBL)than in adult worm(AW)and muscle larva(ML)stages.Immunofluo-rescence results showed that TsNas36 was only localized in the epidermis of NBL.In summary,this study characterized the biological characteristics of the TsNas36 gene and found that this gene is highly period-specific and may be involved in the unique developmental process of NBL.

Objective To investigate the predictive value of integrating clinical pathological characteristics with genetic testing for occult lymph node metastasis(OLNM)in patients with papillary thyroid microcarcinoma(PTMC).Methods A total of 104 PTMC patients admitted to our hospital between May 2023 and May 2025 were included in the study.All patients showed no evidence of suspicious lymph node metastasis on preoperative imaging and underwent standard thyroidectomy with central lymph node dissection.Based on postoperative pathological con-firmation of central lymph node metastasis status,patients were classified into an OLNM-positive group(n=53)and an OLNM-negative group(n=51).Baseline characteristics,clinicopathological features,BRAFV600E gene mutation status,and TERT promoter mutation status were compared between the two groups.To identify factors independently associated with OLNM in PTMC patients,multivariate logistic regression analysis was conducted.The area under the receiver operating characteristic curve(AUC)was utilized to assess the predictive performance of a combined model incorporating clinical,pathological,and genetic features for OLNM.Results Compared with the OLNM-negative group,the OLNM-positive group exhibited significantly higher preoperative thyroid-stimulating hormone(TSH)levels(P<0.05).Moreover,the OLNM-positive group demonstrated significantly greater proportions of tumors with diameter>0.5 cm,multifocality,microcalcifications,capsule invasion,extrathyroidal extension,T3 stage,BRAFV600E mutation,and TERT promoter mutation(all P<0.05).Multivariate logistic regression analysis identified preoperative TSH level,tumor diameter>0.5 cm,multifocal lesions,capsule invasion,extrathyroidal extension,T stage,BRAFV600E mutation,and TERT promoter mutation as independent risk factors for OLNM in patients with PTMC(all P<0.05).ROC curve analysis demonstrated that the integrated model combining clinical pathological features-including tumor diameter,number of lesions,microcalcification,capsule invasion,extrathy-roidal extension,and T stage-with genetic markers(BRAFV600E and TERT promoter mutations)exhibited the highest predictive performance,yielding an AUC of 0.940.This was significantly higher than the model based solely on clinical pathological features(AUC=0.736)or those relying exclusively on genetic testing(BRAFV600E:AUC=0.860;TERT:AUC=0.882),with all comparisons reaching statistical significance(P<0.05).Conclusions The integration of clinical pathological features with genetic testing significantly improved the predictive accuracy of OLNM in PTMC patients,surpassing models based solely on individual clinical pathological characteristics or genetic tests alone.This multimodal strategy offers a robust,evidence-based foundation for personalized surgical planning and enhances the precision of clinical decision-making in the management of PTMC.
