Objective: Patients with atherosclerotic cardiovascular disease (ASCVD) following percutaneous coronary intervention (PCI) are classified as very-high-risk individuals in cardiovascular disease (CVD) risk stratification. The distribution pattern of traditional Chinese medicine (TCM) syndromes in this patient population, as well as its association with blood lipid profiles and clinical prognosis, remains unclear. The present prospective cohort study aims to investigate these correlations, thereby providing insights to enrich the research fields. Methods: We enrolled consecutive patients with ASCVD who underwent PCI at the Integrated Cardiology Unit of China-Japan Friendship Hospital between September 1, 2020 and December 31, 2022. Demographics and clinical characteristics, signs and symptoms defining each TCM syndrome, and fasting venous blood samples were collected at baseline and follow up or upon major adverse cardiovascular events (MACEs). We analyzed the correlation between TCM syndromes, blood lipid profiles, and MACEs, and developed a new joint prognostic model incorporating both TCM syndromes and blood lipids using logistic regression. The analyses were based on detailed baseline and one-year follow-up data. Results: A per-protocol analysis was performed on 586 patients with complete data ultimately. During the one-year follow-up, 174 patients (29.69%) experienced a MACE. We performed statistical analyses on comorbidities, medication, and biochemical indicators across groups defined by TCM syndrome differentiation. When comparing different TCM syndromes, no significant differences were found in age, body mass index (BMI), history of revascularization, comorbidities, family history of CVD, smoking or drinking, or statin intensity (P > 0.05). Patients with intertwined phlegm and blood stasis syndrome exhibited significantly higher levels of total cholesterol (TC, 5.27 ± 1.18 mmol/L, P < 0.001), triglyceride (TG, 1.96 ± 1.33 mmol/L, P = 0.008), low-density lipoprotein cholesterol (LDL-C, 3.35 ± 0.79 mmol/L, P < 0.001), and high-density lipoprotein cholesterol (HDL-C, 1.24 ± 0.81 mmol/L, P < 0.001) compared with those with other TCM syndromes combined. A multivariable logistic regression model was constructed to predict MACEs. The model included TCM syndrome type [with intertwined phlegm and blood stasis as a predictor, adjusted odds ratio (OR) = 1.413, 95% confidence interval (CI): 0.517 – 3.864, P = 0.501], age (adjusted OR = 0.97, 95% CI: 0.955 – 1.001, P = 0.057), male gender (adjusted OR = 0.698, 95% CI: 0.416 – 1.170, P = 0.173), TC (adjusted OR = 1.004, 95% CI: 0.513 – 1.965, P = 0.990), and LDL-C (adjusted OR = 5.825, 95% CI: 2.214 – 15.326, P < 0.001). This model demonstrated good discriminatory ability for MACEs in post-PCI ASCVD patients [the area under the receiver operating characteristic (ROC) curve (AUC) = 0.865, 95% CI: 0.816 – 0.914]. Conclusion The intertwined phlegm and blood stasis TCM syndrome is associated with a distinct atherogenic lipid profile characterized by elevated levels of TC and LDL-C. The prognostic model that incorporates this TCM syndrome type along with conventional lipid parameters (TC and LDL-C) shows good discriminatory ability for predicting MACEs in ASCVD patients after PCI, underscoring the potential clinical utility of integrating TCM syndrome differentiation into CVD risk assessment.

OBJECTIVE: Salt-processed Psoraleae Fructus (SPF) is widely used as a phytoestrogen-like agent in the treatment of osteoporosis. However, due to improper clinical use or misuse, resulting in liver damage. In this study, network pharmacology was employed to analyze the mechanism of cholestatic liver damage. An adeno-associated virus overexpressing SULT1E1 (rAAV8-SULT1E1) was constructed and the hepatotoxicity of SPF, psoralen, and isopsoralen was determined. METHODS: By utilizing three databases inclding TCMSP, TCMID, and BATMAN- TCM, the targets of the three databases were summarized, and a total of 45 psoralen compounds were included. Network pharmacology analysis was then performed. The adenoviral vectors were injected into the tail vein of C57BL6 mice to elucidate the role of SULT1E1 in SPF-induced cholestasis-mediated hepatotoxicity in vivo. SPF (10 g/kg), psoralen, and isopsoralen (50 mg/kg each) were intragastrically administered to mice for 30 d. B-ultrasound and samples were collected and examined for follow-up experiments. RESULTS: A total of 854 targets were predicted for 45 active components, with 151 cholestasis-mediated hepatotoxicity-related disease targets obtained for SPF. A total of 126 pathways were enriched based on KEGG pathway analysis, with the "estrogen signaling pathway" identified as one of the top 20 pathways. In terms of pathological hepatic changes, treated mice had visually swollen hepatocytes, dilated bile ducts, and elevated serum biochemical markers, which were more prominent in mice treated with isopsoralen than in those treated with other compounds. Notably, the overexpression of SULT1E1 could reverse liver damage in each treatment group. B-ultrasound was used to observe the size of the gallbladder in vivo. The size of the gallbladder was found to significantly increase on day 30 after treatment in the SPF-, psoralen-, and isopsoralen-treated groups, especially the SPF group. Compared with the expression levels in the negative control group (rAAV8-empty + con), the expression levels of FXR, Mrp2, Bsep, SULT1E1, SULT2A1, Ntcp, and Nrf2 decreased, whereas those of CYP7a1 and IL-6 increased in the SPF-, psoralen-, and isopsoralen-treated groups. CONCLUSION The overexpression of SULT1E1 could alleviate the decreased or increased expression of indicators, indicating that SULT1E1 is an important target gene for SPF-induced liver damage. The severity of liver damage was significantly lower in the rAAV8-SULT1E1 groups than in the rAAV8-empty groups.

ObjectiveTo investigate whether the effect of Taohong Siwutang on cerebral ischemia-reperfusion （CIRI） injury in rats is related to the regulation of astrocyte polarization and explore the related mechanism. MethodsEighty-four male SD rats were randomly assigned to the following groups： A sham operation group， a model group， Taohong Siwutang treatment groups （low dose， medium dose， and high dose）， ligustrazine phosphate tablet （LPT） group， and AG490 group. All groups， except for the sham operation group， underwent middle cerebral artery occlusion/reperfusion （MCAO/R） modeling and were treated for seven days. The neurological impairment was evaluated using the Longa score. The volume of cerebral infarction was assessed through 2，3，5-triphenyltetrazolium chloride （TTC） staining. Real-time fluorescent quantitative polymerase chain reaction （Real-time PCR） and Western blot analyses were performed to analyze the mRNA and protein expression levels of cortical complement 3 （C3）， S100 calcium-binding protein A10 （S100A10）， Janus kinase 2 （JAK2）， and signal transducer and activator of transcription 3 （STAT3）. Additionally， protein expression levels of vascular endothelial growth factor-A （VEGF-A） were assessed， and the mRNA expression levels of inflammatory factors， including interleukin-6 （IL-6）， interleukin-1β （IL-1β）， and tumor necrosis factor-α （TNF-α）， were evaluated. Glial fibrillary acidic protein （GFAP） and C3， S100A10 and Co-localization was detected via immunofluorescence double staining. Lastly， VEGF expression levels were measured using enzyme-linked immunosorbent assay （ELISA）. ResultsCompared with the sham operation group， the model group showed a significant increase in cerebral infarction volume and neurological impairment （P<0.01）. C3 protein levels were elevated， while S100A10 levels were decreased. Pathway-related markers were significantly upregulated （P<0.05， P<0.01）， and VEGF-A protein levels were significantly reduced （P<0.01）. The mRNA expression of inflammatory factors was significantly upregulated （P<0.01）. Co-localization analysis showed significantly increased GFAP and C3 fluorescence intensity （P<0.01） and greatly decreased GFAP and S100A10 fluorescence intensity （P<0.01）. Additionally， VEGF content was significantly elevated （P<0.01）. Compared with the model group， medium- and high-dose Taohong Siwutang and LPT groups exhibited a significant reduction in cerebral infarction volume and neurological impairment （P<0.01）. Groups treated with low， medium， and high doses of Taohong Siwutang and LPT group exhibited a decrease in C3 protein expression levels and an increase in S100A10 expression levels （P<0.01）. In the high-dose Taohong Siwutang and AG490 groups， both protein and mRNA expression of C3 and pathway-related markers were significantly downregulated （P<0.05， P<0.01）， while S100A10 expression and VEGF-A protein levels were significantly increased （P<0.01）. Additionally， the mRNA expression levels of inflammatory factors were significantly reduced （P<0.01）. The co-localization fluorescence intensity of GFAP and C3 significantly decreased （P<0.01）， while that of GFAP and S100A10 greatly increased （P<0.01）. Furthermore， VEGF content exhibited a marked elevation （P<0.01）. ConclusionTaohong Siwutang exerts a protective effect in rats with cerebral CIRI injury. The underlying mechanism is associated with the downregulation of the JAK2/STAT3 signaling pathway， promotion of A2-type astrocyte polarization， reduction of inflammatory factor release， and enhancement of VEGF production.

OBJECTIVES: To investigate the risk factors of overall postoperative complications in elderly patients undergoing gastrointestinal surgeries. METHODS: This study was conducted among a total of 1388 elderly patients, who underwent elective gastrointestinal surgeries at 17 centers across China between April, 2020 and April, 2022. The primary outcome was the incidence of postoperative complications within 30 days, including procedure-related, neuropsychiatric, respiratory, cardiovascular, and gastrointestinal complications as well as acute kidney injury. Baseline characteristics, preoperative psychological and functional status, intraoperative anesthesia and surgical factors, intraoperative medication, use of nerve block, and postoperative analgesia methods were compared between the patients experiencing one or more postoperative complications and those without complications. Univariate and multivariate logistic regression analyses were performed to identify the independent risk factors for postoperative complications. The relationship between postoperative acute pain and each type of complication were explored. RESULTS: The incidence of overall postoperative complications was 50.8% (705/1388) in these patients. Multivariate analysis showed that age (OR: 1.026; 95% CI: 1.006-1.046), prognostic nutritional index (OR: 0.998; 95% CI: 0.997-1.000), preoperative EuroQol-5 dimensions score (OR: 0.094; 95% CI: 0.018-0.500), blood loss (OR: 1.002; 95% CI: 1.001-1.003), and acute postoperative pain (OR: 1.308; 95% CI: 1.033-1.657) were significantly associated with the occurrence of postoperative complications. Specifically, patients experiencing severe postoperative pain had a significantly higher incidence of neuropsychiatric (27.2% vs 19.8%), procedure-related (17.3% vs 10.2%), and cardiovascular complications (3.6% vs 1.7%). CONCLUSIONS An advanced age, a low preoperative nutritional index, a poor quality of life score, a greater volume of intraoperative blood loss, and acute postoperative pain are independent risk factors for postoperative complications in elderly patients undergoing gastrointestinal surgeries. There is a significant association between acute postoperative pain and multi-system complications.

Apical microsurgery is accurate and minimally invasive, produces few complications, and has a success rate of more than 90%. However, due to the lack of awareness and understanding of apical microsurgery by dental general practitioners and even endodontists, many clinical problems remain to be overcome. The consensus has gathered well-known domestic experts to hold a series of special discussions and reached the consensus. This document specifies the indications, contraindications, preoperative preparations, operational procedures, complication prevention measures, and efficacy evaluation of apical microsurgery and is applicable to dentists who perform apical microsurgery after systematic training.

Pulpotomy, which belongs to vital pulp therapy, has become a strategy for managing pulpitis in recent decades. This minimally invasive treatment reflects the recognition of preserving healthy dental pulp and optimizing long-term patient-centered outcomes. Pulpotomy is categorized into partial pulpotomy (PP), the removal of a partial segment of the coronal pulp tissue, and full pulpotomy (FP), the removal of whole coronal pulp, which is followed by applying the biomaterials onto the remaining pulp tissue and ultimately restoring the tooth. Procedural decisions for the amount of pulp tissue removal or retention depend on the diagnostic of pulp vitality, the overall treatment plan, the patient's general health status, and pulp inflammation reassessment during operation. This statement represents the consensus of an expert committee convened by the Society of Cariology and Endodontics, Chinese Stomatological Association. It addresses the current evidence to support the application of pulpotomy as a potential alternative to root canal treatment (RCT) on mature permanent teeth with pulpitis from a biological basis, the development of capping biomaterial, and the diagnostic considerations to evidence-based medicine. This expert statement intends to provide a clinical protocol of pulpotomy, which facilitates practitioners in choosing the optimal procedure and increasing their confidence in this rapidly evolving field.

Intentional tooth replantation (ITR) is an advanced treatment modality and the procedure of last resort for preserving teeth with inaccessible endodontic or resorptive lesions. ITR is defined as the deliberate extraction of a tooth; evaluation of the root surface, endodontic manipulation, and repair; and placement of the tooth back into its original socket. Case reports, case series, cohort studies, and randomized controlled trials have demonstrated the efficacy of ITR in the retention of natural teeth that are untreatable or difficult to manage with root canal treatment or endodontic microsurgery. However, variations in clinical protocols for ITR exist due to the empirical nature of the original protocols and rapid advancements in the field of oral biology and dental materials. This heterogeneity in protocols may cause confusion among dental practitioners; therefore, guidelines and considerations for ITR should be explicated. This expert consensus discusses the biological foundation of ITR, the available clinical protocols and current status of ITR in treating teeth with refractory apical periodontitis or anatomical aberration, and the main complications of this treatment, aiming to refine the clinical management of ITR in accordance with the progress of basic research and clinical studies; the findings suggest that ITR may become a more consistent evidence-based option in dental treatment.

Ischemic stroke(IS)is a disease caused by insufficient blood and oxygen supply to cerebral vessels,with the main clinical manifestations of hemiplegia,sensory disturbance,aphasia,and ataxia.Studies have shown that hypoxia-inducible factor 1α(HIF-1α),as the core regulatory element of oxygen homeostasis,can be rapidly activated under hypoxia/ischemia conditions,thereby playing an important role in the pathophysiology of IS.In recent years,more and more articles have shown that the active components of tradi-tional Chinese medicine,Chinese patent drugs,and compound traditional Chinese medicine prescriptions can effectively regulate the HIF-1α-related signaling pathway in the treatment of IS,but there is no systematic summary on regulation of the HIF-1α signaling pathway in the treatment of IS.Therefore,this article mainly summarizes the structure and physiological activity of HIF-1α and its mechanisms of action in IS and reviews related studies on Chinese medicine monomers and compound prescriptions in the treatment of IS in the past five years in China and globally.It is pointed out that the Chinese medicine monomers and compound prescriptions can repair brain tissue,alleviate brain tissue damage,and exert a therapeutic effect on IS by regulating the HIF-1α pathway to promote an-giogenesis,inhibit neuroinflammation and oxidative stress,promote energy metabolism,and repair blood-brain barrier damage.

Objective To investigate the effects of curcumin on the proliferation,migration,invasion,and apoptosis of pheochromocytomacell line PC12.Methods PC12 cells were incubated with different concentrations of curcumin.Cell proliferation was assessed using the CCK-8 assay to determine the IC50.The scratch assay was used to evaluate cell migration and Transwell chambers were employed to assess cell invasiveness.Flow cytometry was used to analyze apoptosis.qPCR was conducted to measure the mRNA expression of pro-apoptotic(Bax)and anti-apoptotic(Bcl-2)genes,and Western blot was performed to detect Bax and Bcl-2 protein expressions.Results Curcumin(10-80 μmol/L)inhibited PC12 cell proliferation in a concentration-dependent manner,with an IC50 as 29 μmol/L.Curcumin also suppressed PC12 cell migration in a concentration-dependent mode;the migration rate decreased from 66％in the control group down to 51％,5％,and 0.5％in the 10,20,and 30 μmol/L curcumin groups,respectively.Curcumin at concentrations of 20-30 μmol/L significantly reduced PC12 cell invasiveness(P<0.000 1).Moreover,curcumin significantly promoted PC12 cell apoptosis;the percentage of apoptotic cells increased by 2.25％,18.53％,and 26.89％in the 10,20,and 30 μmol/L curcumin groups as compared to those of control group,respectively.Curcumin treatment resulted in a significant up-regulation of Bax mRNA and protein expression,and a significant down-regulation of Bcl-2 mRNA and protein expression(P<0.05).Conclusions Curcumin may significantly inhibit the proliferation,migration,and invasion of PC12 cells and arouse cell apopto-sis.Its pro-apoptotic effect may be associated with alterations in the expression of Bax and Bcl-2 genes.
