ObjectiveTo investigate the mechanism by which Wendantang regulates the silent information regulator 3 (SIRT3)/peroxisome proliferator-activated receptor-gamma coactivator-1α (PGC-1α) pathway to influence energy metabolism and thereby prevent and treat myocardial ischemia (MI) in a rat model of hyperlipidemia (HL). MethodsThirty SD rats were randomly assigned into five groups: control, model, low-dose (3.702 g·kg-1·d-1) Wendantang, high-dose (7.404 g·kg-1·d-1) Wendantang, and positive control (trimetazidine, 0.006 g·kg-1·d-1), with six rats in each group. The control group was fed normally, while the other groups were fed with a high-fat diet for six weeks for the modeling of HL. Subsequently, the drug intervention groups were administrated with corresponding drugs by gavage, and the control and model groups received an equivalent volume of normal saline for 14 days. One hour after the last gavage, the other groups except the control group were injected intraperitoneally with posterior pituitary hormone (30 U·kg-1) to induce MI. Electrocardiography (ECG) was employed to detect changes in the electrocardiogram. Hematoxylin-eosin staining was performed to observe cardiac pathological changes. Enzyme-linked immunosorbent assay was employed to measure the serum levels of cardiac troponin I(cTnI), myoglobin (MYO), and creatine kinase-MB (CK-MB). Colorimetry was used to determine the levels of total cholesterol (TC) and triglycerides (TG) in the serum and ATP, malondialdehyde (MDA), and superoxide dismutase (SOD) in the myocardial tissue. Western blot was employed to determine the protein levels of SIRT3, PGC-1α, adenosine monophosphate-activated protein kinase (AMPK), and phosphorylated AMPK (p-AMPK) in the myocardial tissue. Real-time PCR was employed to measure the mRNA levels of SIRT3, PGC-1α, and AMPKα in the myocardial tissue. ResultsCompared with the control group, the model group showed significant J-point deviation and elevation in the ECG image, increased heart rate, disarrangement of myocardial fibers with unclear boundaries, elevated levels of CK-MB, cTnI, MYO, TC, and TG (P<0.05, P<0.01), declined levels of SOD and ATP (P<0.01), down-regulated mRNA levels of SIRT3, PGC-1α, and AMPK (P<0.05), and down-regulated protein levels of SIRT3, PGC-1α, and p-AMPK (P<0.05). Compared with the model group, the low-dose and high-dose Wendantang groups and the trimetazidine group showed inhibited J-point deviation and elevation in the ECG image, slowed heart rate, reduced inflammatory cell infiltration, alleviated disarrangement of myocardial fibers, declined levels of CK-MB, cTnI, MYO, TC, and TG (P<0.05, P<0.01), elevated level of SOD (P<0.01), up-regulated mRNA levels of SIRT3, PGC-1α, and AMPK (P<0.05, P<0.01) and up-regulated protein levels of SIRT3, PGC-1α, and p-AMPK (P<0.05, P<0.01). ConclusionWendantang can effectively intervene in HL-associated MI in rats by reducing oxidative stress in myocardial cells, alleviating lipid metabolism disorders, and improving myocardial energy metabolism via the SIRT3/PGC-1α signaling pathway.

ObjectiveBy comparing the composition and content of volatile components in raw products, wine-washed products and wine-fried products of Ligusticum sinense cv. Chaxiong rhizome(LSCR), to investigate the influence of wine processing on the volatile components of LSCR, in order to provide a basis for the development of quality standards for LSCR and its processed products. MethodsElectronic nose was used to identify the odors of LSCR, wine-washed and wine-fried LSCR, and their volatile components were detected by headspace gas chromatography-mass spectrometry(HS-GC-MS), and the relative mass fractions of these components were determined by peak area normalization method. Principal component analysis(PCA) and orthogonal partial least squares-discriminant analysis(OPLS-DA) were performed on the obtained sample data by SIMCA 14.1 software, and the differential components of LSCR, wine-washed and wine-fried LSCR were screened according to the variable importance in the projection(VIP) value>1. Pearson correlation analysis was used to explore the relationship between volatile differential flavor components and electronic nose sensors. ResultsElectronic nose detection results showed that there were significant differences in the odors of LSCR, wine-washed and wine-fried LSCR, mainly reflected in the sensors S2, S4, S5, S6, S11, S12, S13. And a total of 62 compounds were identified from LSCR and its wine-processed products, among which 46, 50 and 51 compounds were identified from LSCR, wine-fried and wine-washed LSCR, respectively. There were 21 differential components between the raw products and wine-fried products, of which 10 components were increased and 11 were decreased after processing. There were 20 differential components between the raw products and wine-washed products, of which 11 constituents increased and 9 decreased after processing. There were 17 differential components between the wine-wash products and wine-fried products. Compared with the wine-washed products, the contents of 13 components in the wine-fried products increased, and the contents of 4 components decreased. The increasing trend of the content of phthalides in the wine-washed products was more obvious than that in the wine-fried products, but the content of total volatile components was higher in the wine-fried products than the wine-washed products. Correlation analysis showed that there were different degrees of correlation between the 7 differential sensors of electronic nose and 24 differential volatile components, mainly phthalides and olefins. ConclusionThe odor and the content of volatile components in LSCR changed obviously after wine processing, and n-butylphthalide, Z-butylidenephthalide and E-ligustilide can be used as the candidate differential markers of volatile components in LSCR before and after wine processing.

Objective To examine the safety, efficacy and durability of totally endoscopic minimally invasive (TEMI) mitral valve repair in Barlow’s disease (BD). Methods A retrospective study was performed on patients who underwent mitral valve repair for BD from January 2010 to June 2021 in the Guangdong Provincial People’s Hospital. The patients were divided into a MS group and a TEMI group according to the surgery approaches. A comparison of the clinical data between the two groups was conducted. Results A total of 196 patients were enrolled, including 133 males and 63 females aged (43.8±14.9) years. There were 103 patients in the MS group and 93 patients in the TEMI group. No hospital death was observed. There was a higher percentage of artificial chordae implantation in the TEMI group compared to the MS group (P=0.020), but there was no statistical difference between the two groups in the other repair techniques (P>0.05). Although the total operation time between the two groups was not statistically different (P=0.265), the TEMI group had longer cardiopulmonary bypass time (P<0.001) and aortic clamp time (P<0.001), and shorter mechanical ventilation time (P<0.001) and postoperative hospitalization time (P<0.001). No statistical difference between the two groups in the adverse perioperative complications (P>0.05). The follow-up rate was 94.2% (180/191) with a mean time of 0.2-12.4 (4.0±2.4) years. Two patients in the MS group died with non-cardiac reasons during the follow-up period. The 3-year, 5-year and 10-year overall survival rates of all patients were 100.0%, 99.2%, 99.2%, respectively. Compared with the MS group, there was no statistical difference in the survival rate, recurrence rate of mitral regurgitation, reoperation rate of mitral valve or adverse cardiovascular and cerebrovascular events in the TEMI group (P>0.05). Conclusion TEMI approach is a safe, feasible and effective approach for BD with a satisfying long-term efficacy.

Objective To investigate the safety, economic benefits and psychological effects of day breast conserving surgery for breast cancer. Methods The demographic data and clinical data of breast cancer patients undergoing day (day surgery group) and ward (ward surgery group) breast conserving surgeries in West China Hospital of Sichuan University from March 2020 to June 2021 were retrospectively collected; the demographic data, clinical data, medical and related transportation costs, and preoperative and postoperative BREAST-Q scores of breast cancer patients undergoing day (day surgery group) and ward (ward surgery group) breast conserving surgery in West China Hospital of Sichuan University from June 2021 to June 2022 were prospectively collected. The safety, economic benefit, and psychological satisfaction of day surgery was analyzed. Results A total of 42 women with breast cancer were included in the retrospective study and 39 women with breast cancer were included in the prospective study. In both prospective and retrospective studies, the mean age of patients in both groups were <50 years. There were only statistical differences between the two groups in the aspects of hypertension (P=0.022), neoadjuvant chemotherapy (P=0.037) and postoperative pathological estrogen receptor (P=0.033) in the prospective study. In postoperative complications, there were no statistical differences in the surgical-related complications or anesthesia-related complications between the two groups in either the prospective study or the retrospective study (P>0.05). In terms of the overall cost, we found that the day surgery group was more economical than the ward surgery group in the prospective study (P=0.002). There were no statistical differences in postoperative psychosocical well-being, sexual well-being, satisfaction with breasts or chest condition between the two groups (P>0.05). Conclusion It is safe and reliable to carry out breast conserving surgery in day surgery center under strict management standards, which can save medical costs and will not cause great psychological burden to patients.

The development of traditional Chinese medicine (TCM) diagnosis and treatment has undergone multiple paradigms, evolving from sporadic experiential practices to systematic approaches in syndrome differentiation and treatment and further integration of disease and syndrome frameworks. TCM is a vital component of the medical system, valued alongside Western medicine. Treatment based on syndrome differentiation embodies both personalized treatment and holistic approaches; however, the inconsistency and lack of stability in syndrome differentiation limit clinical efficacy. The existing integration of diseases and syndromes primarily relies on patchwork and embedded systems, where the full advantages of synergy between Chinese and Western medicine are not fully realized. Recently, driven by the development of diagnosis and treatment concepts and advances in analytical technology, Western medicine has been rapidly transforming from a traditional biological model to a precision medicine model. TCM faces a similar need to progress beyond traditional syndrome differentiation and disease-syndrome integration toward a more precise diagnosis and treatment paradigm. Unlike the micro-level precision trend of Western medicine, precision diagnosis and treatment in TCM is primarily reflected in data-driven applications that incorporate information at various levels, including precise syndrome differentiation, medication, disease management, and efficacy evaluation. The current priority is to accelerate the development of TCM precision diagnosis and treatment technology platforms and advance discipline construction in this area.

ObjectiveTo investigate the expression level of HBV cccDNA in patients in the convalescence stage of hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF) and its correlation with HBV markers and liver histopathological changes. MethodsA total of 30 patients in the convalescence stage of HBV-ACL who were hospitalized in The Ninth Hospital of Nanchang from January 2015 to October 2023 were enrolled as liver failure group, and 9 patients with chronic hepatitis B (CHB), matched for sex and age, were enrolled as control group. The content of HBV cccDNA in liver tissue was measured, and its correlation with clinical data and laboratory markers was analyzed. The independent-samples t test or the Mann-Whitney U test was used for comparison of continuous data between two groups, and a one-way analysis of variance or the Kruskal-Wallis H test was used for comparison between multiple groups; the Fisher’s exact test was used for comparison of categorical data between groups. A Spearman correlation analysis was performed. ResultsThe liver failure group had a significantly lower content of HBV cccDNA in liver tissue than the control group (-0.92±0.70 log10 copies/cell vs -0.13±0.91 log10 copies/cell, t=2.761, P=0.009). In the liver failure group, there was no significant difference in the content of HBV cccDNA in liver tissue between the HBeAg-positive patients and the HBeAg-negative patients (P>0.05); there was no significant difference in the content of HBV cccDNA in liver tissue between the patients with different grades (G0-G2, G3, and G4) of liver inflammatory activity (P>0.05); there was no significant difference in the content of HBV cccDNA in liver tissue between the patients with different stages (S0-S2, S3, and S4) of liver fibrosis (P>0.05); there was no significant difference in the content of HBV cccDNA in liver tissue between the patients with negative HBV DNA and those with positive HBV DNA (P>0.05). For the liver failure group, the content of HBV cccDNA in liver tissue was positively correlated with the content of HBV DNA in liver tissue (r=0.426, P=0.043) and was not significantly correlated with the content of HBV DNA in serum (P>0.05). ConclusionThere is a significant reduction in the content of HBV cccDNA in liver tissue in the convalescence stage of HBV-ACLF. HBV cccDNA exists continuously and stably in liver tissue and can better reflect the persistent infection and replication of HBV than HBV DNA in serum and liver tissue.

Portal vein embolization (PVE) can induce atrophy of the embolized lobe and compensatory regeneration of the non-embolized lobe. However, due to inadequate regeneration of future liver remnant (FLR) after PVE, some patients remain unsuitable for hepatectomy after PVE. In recent years, liver venous deprivation (LVD), which combines PVE with hepatic vein embolization (HVE), has induced enhanced FLR regeneration. Compared with associating liver partition and portal vein ligation for staged hepatectomy (ALPPS), LVD triggers faster and more robust FLR regeneration, with lower incidence rate of postoperative complications and mortality rate. By reviewing related articles on LVD, this article introduces the effectiveness of LVD and analyzes the differences and safety of various technical paths, and it is believed that LVD is a safe and effective preoperative pretreatment method.

Rheumatoid arthritis belongs to arthralgia syndrome in the theory of traditional Chinese medicine, and cold-dampness obstruction syndrome and dampness-heat obstruction syndrome are core syndromes and main syndrome differentiation types of this disease. Fine therapeutic effects have been obtained in the long-term clinical practice of many famous traditional Chinese medicine practitioners following the syndrome differentiation and treatment based on the guiding principles of cold and heat. To adapt to the clinical diagnosis practice of combining disease differentiation and syndrome differentiation, and to better carry out basic research on integrated Chinese and Western medicine and preclinical study on new traditional Chinese medicines, Guidelines for Establishing Animal Models of Rheumatoid Arthritis with Cold-Dampness Obstruction Syndrome and Dampness-Heat Obstruction Syndrome (hereinafter referred to as the Guidelines) were compiled by our research group, in cooperation with the renowned experts in research fields including traditional Chinese medicine, clinical medicine, zoology and evidence-based medicine, which provide a meaningful reference for scientific research, teaching and clinical applications. The compilation process of the Guidelines was guided by the theory of disease and syndrome integration and the principles of "evidence takes the main place, consensus plays an auxiliary role, and experience serves as the reference". Based on the comprehensive evaluation of pathogenesis homology, behavioral phenotypic consistency, and drug treatment predictability compared between animal models and human diseases, by the nominal group method, "recommendations" were formed for recommendations supported by evidence, and "consensus recommendations" were formed for recommendations not supported by evidence. Guidelines were formed involving content such as animal types, arthritis modeling methods, external stimulation conditions, and modeling assessment indicators during the establishment of the animal models of rheumatoid arthritis with cold-dampness obstruction syndrome and dampness-heat obstruction syndrome. The Guidelines are applicable for the disease and syndrome research on rheumatoid arthritis, investigation of therapeutic mechanisms, and development of new traditional Chinese medicine. The Guidelines also provide a reference for the establishment of guidelines on other types of diseases and syndromes combined with animal models to further promote the modernization of traditional Chinese medicine research and its integration with international academic development.
