ObjectiveTo explore the improving effect of Huangqi Chifengtang(HCT) on atherosclerosis(AS), and elucidate its mechanism in relation to adenosine monophosphate-activated protein kinase(AMPK)/peroxisome proliferator-activated receptor α(PPARα) signaling pathway and nucleotide-binding oligomerization domain(NOD)-like receptor thermal protein domain associated protein 3(NLRP3) inflammasome. MethodsEight C57BL/6J mice were set as the normal group, and 32 ApoE-/- mice were randomly divided into the model group, the positive drug group(atorvastatin, 5 mg·kg-1·d-1), HCT low- and high-dose groups(1.95, 3.90 g·kg-1·d-1). ApoE-/- mice were fed with high-fat and high-cholesterol feed to establish an AS mouse model. After modeling, they were orally administered corresponding dose of drugs for 28 days, while the normal and model groups received an equal volume of physiological saline via oral gavage. Hematoxylin-eosin(HE) staining was used to observe the pathological status of the aorta and liver in mice, Biochemical testing and enzyme-linked immunosorbent assay(ELISA) were used to detect the levels of total cholesterol(TC), triglycerides(TG), low-density lipoprotein cholesterol(LDL-C), alanine aminotransferase(ALT), aspartate aminotransferase(AST), C-reactive protein(CRP), interleukin(IL)-1β, IL-18 in the serum, as well as superoxide dismutase(SOD), malondialdehyde(MDA), and reduced glutathione(GSH) in the liver. Real-time fluorescence quantitative polymerase chain reaction(Real-time PCR) was used to measure the mRNA expression levels of NLRP3, apoptosis-associated speck-like protein(ASC), cysteinyl aspartate specific proteinase-1(Caspase-1), Toll-like receptor 4(TLR4) in the aorta, and fatty acid synthase(FAS), stearoyl-CoA desaturase 1(SCD1), PPARα, and carnitine palmitoyltransferase 1A(CPT1A) in the liver. Immunohistochemistry was used to determine the protein expressions of NLRP3, Caspase-1, and ASC in the aorta, and Western blot was used to measure the protein expressions of AMPK, p-AMPK, sterol regulatory element binding protein-1c(SREBP-1c), CPT1A, and FAS in the liver. ResultsCompared with the normal group, the model group showed a significant increase in lipid plaque deposition in the aorta and lipid accumulation in the liver, the levels of TC, TG, LDL-C, AST, ALT, IL-1β, IL-18 and CRP in the serum were significantly increased(P<0.01), and the mRNA and protein expressions of aortic TLR4, NLRP3, Caspase-1 and ASC were significantly upregulated(P<0.01). The levels of SOD and GSH in the liver were significantly reduced, while the level of MDA was significantly increased(P<0.01). The mRNA expressions of FAS and SCD1 in the liver were significantly downregulated, while the mRNA expressions of PPARα and CPT1A were significantly upregulated. The protein expressions of p-AMPK/AMPK and CPT1A in the liver were significantly reduced, while the expressions of SREBP-1c and FAS proteins were significantly increased(P<0.01). Compared with the model group, the low- and high-dose HCT groups showed significant improvements in aortic plaques and hepatic lipid deposition. The levels of TC, LDL-C, AST, IL-1β and IL-18 in the serum of the low-dose HCT group, as well as TC, TG, LDL-C, AST, ALT, IL-1β, IL-18 and CRP in the serum of the high-dose HCT group, were significantly reduced(P<0.01). The mRNA expressions of TLR4, NLRP3 and Caspase-1 in the aorta of the low-dose HCT group, as well as TLR4, NLRP3, Caspase-1 and ASC in the aorta of the high-dose HCT group, were significantly downregulated(P<0.01). The protein expressions of Caspase-1 and ASC in the aorta of the low-dose HCT group, as well as NLRP3, Caspase-1 and ASC in the high-dose HCT group, were significantly downregulated(P<0.01). The levels of SOD and GSH in the liver of the low- and high-dose HCT groups were significantly increased, while the level of MDA in the high-dose HCT group was significantly decreased(P<0.05, P<0.01). In the HCT-treated group, the mRNA expressions of FAS and SCD1 in the liver were significantly upregulated, while the mRNA expressions of PPARα and CPT1A were significantly downregulated, the protein expressions of p-AMPK/AMPK and CPT1A in the liver were significantly increased, while the protein expressions of SREBP-1c and FAS were significantly decreased(P<0.05, P<0.01). ConclusionHCT can improve lipid metabolism by activating the AMPK/PPARα pathway and inhibit NLRP3 inflammasome-mediated inflammatory responses, thereby reducing hepatic lipid deposition and AS plaque formation.

ObjectiveThis paper aims to conduct the feature analysis and correlation analysis on the ocular collateral features and differential metabolites in patients with chronic hepatitis B (CHB) complicated by glucose metabolism disorder (GMD),particularly those with the damp-heat syndrome type,by integrating shadowless scleral imaging and metabolomics technologies. MethodsA total of 313 patients were recruited from the Hepatology and Endocrinology Outpatient Departments of Public Health Clinical Center of Chengdu according to the inclusion/exclusion criteria,and they were divided into a CHB group and a CHB complicated by GMD groups (damp-heat syndrome group and non-damp-heat syndrome group). All patients underwent high-definition ocular image acquisition and feature extraction using an intelligent analysis system for shadowless scleral imaging to analyze the differences in the counting of morphological feature scores of ocular collaterals among groups. By using a digital sampling method,24 patients from each group were randomly selected,along with 20 healthy volunteers,for untargeted metabolomic analysis of peripheral serum. Differential metabolites were identified,statistically analyzed,and subjected to potential biomarker analysis and pathway enrichment. Spearman method was performed to conduct the correlation analysis on the differential ocular collateral features and differential metabolites,followed by correlation network construction. ResultsCompared with those in the CHB group,patients with CHB complicated by GMD showed significant changes in ocular collateral feature scores such as "hillock","blood vessels",and "pale dusky coloration" (P<0.05). In comparison with those in the healthy group,metabolites including N-acetylglucosamine,acetylhomoserine,and myo-inositol (AUC>0.7) were identified as potential biomarkers for the disease. Compared with those in the CHB complicated by GMD group with non-damp-heat syndrome,patients with damp-heat syndrome exhibited significant changes in feature scores of "plaques","yellow coloration","spleen",and "gallbladder" (P<0.05). In comparison with those in the healthy group,metabolites such as O2′-4a-cyclic tetrahydrobiopterin,theobromine,xanthurenic acid,and L-glutamic acid 5-phosphate (AUC>0.7) were identified as potential biomarkers for the damp-heat syndrome type. The Spearman correlation analysis reveals weak to moderate linear correlations between the differential scleral collateral features and metabolites. By constructing a "disease-syndrome" network of ocular diagnosis and metabolites,"xanthurenic acid-gallbladder" and "theobromine-plaque/yellow coloration" were identified as specific molecular-phenotypic correlated biomarker clusters for CHB complicated by GMD with dampness-heat syndrome. ConclusionPatients with CHB complicated by GMD demonstrate differential ocular diagnostic features and serum metabolites corresponding to disease states and dampness-heat syndrome. These objective biomarkers can guide both clinical syndrome differentiation and medication. The macro-micro integration based on ocular feature clusters and potential metabolic biomarkers offers an innovative approach to a combined traditional Chinese and Western medicine diagnosis and treatment model for this disease.

Traditional Chinese medicine(TCM)serves as a treasure trove of ancient knowledge,holding a crucial position in the medical field.However,the exploration of TCM's extensive information has been hindered by challenges related to data standardization,completeness,and accuracy,primarily due to the decen-tralized distribution of TCM resources.To address these issues,we developed a platform for TCM knowledge discovery(TCMKD,https://cbcb.cdutcm.edu.cn/TCMKD/).Seven types of data,including syndromes,formulas,Chinese patent drugs(CPDs),Chinese medicinal materials(CMMs),ingredients,targets,and diseases,were manually proofread and consolidated within TCMKD.To strengthen the integration of TCM with modern medicine,TCMKD employs analytical methods such as TCM data mining,enrichment analysis,and network localization and separation.These tools help elucidate the molecular-level commonalities between TCM and contemporary scientific insights.In addition to its analytical capabilities,a quick question and answer(Q&A)system is also embedded within TCMKD to query the database efficiently,thereby improving the interactivity of the platform.The platform also provides a TCM text annotation tool,offering a simple and efficient method for TCM text mining.Overall,TCMKD not only has the potential to become a pivotal repository for TCM,delving into the pharmaco-logical foundations of TCM treatments,but its flexible embedded tools and algorithms can also be applied to the study of other traditional medical systems,extending beyond just TCM.

Objective:This study aims to investigate the expression of uridine diphosphate-glucose[]pyrophos-phorylase 2(UGP2)in breast cancer(BC)tissues and its oncogenic mechanism,assessing its potential value as a diag-nostic and prognostic biomarker for breast cancer.Methods:(1)Online database analysis was conducted to assess UGP2 mRNA and protein expression levels in breast cancer and explore their correlation with clinical characteristics.Im-munohistochemistry(IHC)was used to verify UGP2 expression in human breast cancer tumor tissues and evaluate its relationship with clinicopathological features.(2)Kaplan-Meier survival analysis and COX regression models were used to analyze the impact of UGP2 expression on breast cancer patient prognosis.(3)Bioinformatics methods were em-ployed to investigate the correlation between UGP2 and tumor immune cell infiltration,and to predict the biological func-tions and associated signaling pathways of UGP2 in breast cancer.Results:(1)The mRNA and protein expression levels of UGP2 were upregulated in breast cancer tissues(both P<0.05),and were negatively correlated with ER-positive and PR-positive status(OR<1,P<0.05),while positively correlated with Ki-67 levels and the triple-negative breast cancer(TNBC)subtype(OR>1,P<0.05).(2)Elevated expression levels of UGP2 were associated with poorer survival rates in breast cancer patients(both P<0.05)and were identified as an independent adverse prognostic factor for breast cancer(HR=1.40,P<0.05).(3)Functional analysis results suggested that UGP2 may promote tumor progression by regulating metabolism,hormone signaling,and the immune microenvironment.Additionally,UGP2 expression was negatively cor-related with NK cell activation status and positively correlated with the inhibitory state.Conclusion:UGP2 expression is elevated in breast cancer tissues and is closely associated with poor patient prognosis.It may promote cancer pro-gression through mechanisms such as metabolic reprogramming and immune suppression.UGP2 shows promise as a potential biomarker and therapeutic target in breast cancer,providing a basis for personalized treatment.

Objective:This study aimed to compare postoperative pain between minimally invasive coronary artery bypass grafting (MICS-CABG) and conventional CABG for multivessel coronary artery disease, comparing baseline characteristics and perioperative data between the two groups, and analyzing risk factors influencing postoperative pain.Methods:A total of 545 patients undergoing elective off-pump coronary artery bypass grafting (OPCABG) for multivessel coronary artery disease at Beijing Anzhen Hospital from July 2022 to July 2023 were included. There were 397 patients in the conventional CABG group (289 males, 108 females, aged 35-77 years) and 148 patients in the minimally invasive CABG group (121 males, 27 females, aged 37-84 years), with 148 patients in each group after propensity score matching. Pain levels were assessed using the Numeric Rating Scale (NRS) at the first 5 days postoperatively (acute postoperative pain, APP) and at 3, 6, and 12 months postoperatively (chronic post-surgical pain, CPSP). Logistic regression was used to analyze risk factors for CPSP at 3 months postoperatively in both groups. Results:Within 48 hours postoperatively, both groups reported maximum NRS pain intensities at rest (NRS 4.0 vs. 6.0) and during activity (NRS 5.2 vs. 7.5). From the third day after surgery, there were no significant differences in resting pain intensity between the two groups, and from the fourth day after surgery, there were no significant differences in pain intensity during movement. With 60.2% in the conventional group and 92.6% in the minimally invasive group experiencing moderate to severe pain at rest (NRS ≥ 4), and 83.5% in the conventional group and 98.0% in the minimally invasive group experiencing moderate to severe pain during activity (NRS ≥ 4). Immediately after drain removal, there was a significant reduction in pain intensity at rest in the minimally invasive group (pre-drain removal NRS 6.0 vs. post-drain removal NRS 2.7), compared to the conventional group (pre-drain removal NRS 4.0 vs. post-drain removal NRS 2.3). However, there was no significant difference in the reduction of pain intensity during activity between the minimally invasive group (pre-drain removal NRS 7.5 vs. post-drain removal NRS 4.2) and the conventional group (pre-drain removal NRS 6.0 vs. post-drain removal NRS 2.7). At 3 months postoperatively, the incidence of CPSP was 35.9% in the conventional group and 35.1% in the minimally invasive group. At 6 months postoperatively, the incidence of CPSP was significantly lower compared to 3 months in both groups (conventional group 8.7% vs. minimally invasive group 6.8%, P<0.001). In the conventional group, higher Europe SCORE Ⅱ was identified as an independent risk factor for CPSP at 3 months postoperatively, while in the minimally invasive group, higher BMI and postoperative use of flurbiprofen for rescue analgesia were identified as independent risk factors. Conclusion:In patients undergoing minimally invasive coronary artery bypass grafting (CABG), the early postoperative acute pain intensity and incidence were higher than those in the conventional CABG group. After drain removal, there were no significant differences in resting pain intensity between the two groups, but pain intensity during movement remained higher in the minimally invasive group compared to the conventional group. The incidence of chronic pain did not differ between the two groups but decreased significantly from 3 months postoperatively. Conventional CABG patients with high preoperative Europe SCORE Ⅱ scores, high preoperative BMI and severe postoperative acute pain tend to have more chronic pain after minimally invasive bypass surgery.

Objective:To evaluate the efficacy and safety of anlotinib neoadjuvant therapy for newly diagnosed locally advanced thyroid cancer (LATC).Methods:Twenty-four newly diagnosed LATC patients (10 males and 14 females, age (47.1±3.3) years) admitted to Affiliated Hospital of Integrated Traditional Chinese and Western Medicine of Nanjing University of Chinese Medicine were prospectively included from January 2023 to April 2024. Patients were given anlotinib neoadjuvant therapy (12mg/d, 2 weeks of medication, 1 week of discontinuation), and the efficacy of the treatment was evaluated by CT and multi-disciplinary treatment at the end of each treatment cycle. Patients assessed as suitable for surgery would be scheduled for surgery, while those who were not suitable for surgery would continue to receive neoadjuvant therapy and periodic evaluations. The primary endpoints were objective response rate (ORR) and disease control rate (DCR), and the R0/1 resection rate and adverse events (AE) after neoadjuvant therapy were observed. Paired- t test was used to analyze the differences between groups, and the Clopper-Person accurate method was used to calculate the bilateral 95% CI of ORR and other indicators. Results:Twenty-four patients received 2(2, 3) cycles of neoadjuvant therapy with anlotinib, of which 23 underwent surgery after anlotinib therapy. After neoadjuvant therapy, the mean maximum diameter of target lesions decreased by 23.5%(95% CI: 2.8%-44.3%) compared with baseline ( t=9.22, P<0.001). The ORR and DCR were 37.5%(95% CI: 18.8%-59.4%) and 100%(95% CI: 85.8%-100%), respectively. About 91.7%(95% CI: 73.0%-99.0%) of patients eventually underwent R0/1 resection. Hand and foot skin reactions, hypertension, oral mucositis, and leukopenia were common AE; grade 4 and 5 AE were not observed. Conclusion:Anlotinib can be safely used as neoadjuvant therapy for newly diagnosed LATC patients with good antitumor effects, providing better surgical opportunities for R0/1 resection.

Objective:To explore the advantages of robotic-arm assisted total hip arthroplasty (rTHA) in acetabular component positioning and lower limb length assessment in patients with severe pelvic coronal tilt.Methods:A retrospective analysis was conducted on the data of 122 patients with unilateral end-stage hip disease and coronal pelvic tilt angle >3° who underwent total hip arthroplasty (THA) at the First Medical Center of PLA General Hospital from June 2022 to December 2023. Among them, 44 patients underwent rTHA, and 78 underwent manual THA (mTHA). The rTHA group included 18 males and 26 females, with an average age of 60.5±9.3 years; the mTHA group included 41 males and 37 females, with an average age of 58.5±8.4 years. Compare the differences in the anteversion angle, abduction angle, pelvic tilt angle, leg length discrepancy (LLD) of the acetabular prosthesis, and the proportions of patients with LLD>0.5 cm and >1 cm between the two groups of patients after surgery. Calculate the proportion of outlier rates of acetabular abduction angle (<30° or >45°), and proportions within Callanan's safe zone. The early efficacy of the hip joint was evaluated by using the modified Harris score and joint range of motion.Results:All patients were followed up for 6 to 12 months, with an average of 8 months. All the surgical incisions of the patients achieved primary healing. Postoperative comparisons showed no statistically significant differences in acetabular abduction angle (39.5°±3.3° vs. 38.4°±7.3°) or anteversion angle (20.7°±1.6° vs. 19.7°±1.6°) between rTHA and mTHA groups ( P>0.05). However, pelvic tilt angle [2.5° (1.1°, 3.6°) vs. 3.5° (2.3°, 5.9°)] showed a statistically significant difference ( U=4.371, P=0.008). The rTHA group exhibited smaller absolute LLD [0.2 (0.1, 0.4) cm vs. 0.5 (0.2, 0.5) cm] and lower proportions of LLD >0.5 cm [14% (6/44) vs. 49% (38/78)] and >1 cm [2% (1/44) vs. 18% (14/78)], with statistical significance ( P<0.05). The rTHA group had a lower outlier rate for acetabular abduction angle (<30°or >45°) compared to the mTHA group [2% (1/44) vs. 33% (26/78)], with statistical significance (χ 2=10.388, P<0.001). Taking the Callanan safety zone as the standard, the proportion of acetabular cups within the safe zone was significantly higher in the rTHA group (98%, 43/44) compared to the mTHA group (67%, 52/78), with a statistically significant difference (χ 2=13.998, P<0.001). The modified Harris score and hip joint range of motion in the mTHA group increased from 47.6±6.6 points and 83° (73°, 88°) before the operation to 83.5±11.2 points and 118° (110°, 122°) at the last follow-up, respectively. The rTHA group increased from 46.5±9.2 points and 79° (71°, 90°) before the operation to 85.0±12.5 points and 124° (116°, 130°) at the last follow-up. The differences in the modified Harris score and hip joint range of motion between the two groups before the operation and at the last follow-up were statistically significant ( P<0.05). However, there was no statistically significant difference between the groups at the last follow-up ( P>0.05). No THA-related complications occurred during follow-up period. Conclusion:For patients with end-stage hip joint diseases with coronal tilt exceeding 3°, robotic-assisted technology significantly improves the accuracy of acetabular component placement during THA and offers better control of postoperative LLD.
