ObjectiveTo clarify the protective effect of Danlou tablet, a representative traditional Chinese medicine of the stagnation of phlegm and blood stasis co-treatment method, on vascular endothelial function in patients with atherosclerosis (AS). MethodsA randomized controlled trial was conducted. From September 2023 to November 2023, a total of 72 patients who were diagnosed at Guang'anmen Hospital, China Academy of Chinese Medical Sciences and met the inclusion and exclusion criteria for carotid atherosclerosis (CAS) combined with coronary atherosclerotic heart disease (CHD) and stable angina pectoris (SAP) were enrolled. The patients were randomly divided into a control group (receiving conventional Western medicine treatment) and an observation group (receiving Danlou tablet combined with conventional Western medicine treatment), with 36 cases in each group. The intervention lasted for 12 weeks. The frequency of angina pectoris attacks was recorded to evaluate the clinical efficacy of Danlou tablet. Peripheral blood samples were collected from patients, and the expression levels of serum endothelial injury markers before and after treatment were detected by enzyme-linked immunosorbent assay (ELISA). The nitrate reductase method was employed to evaluate the protective effect of Danlou tablet on vascular function. The expression levels of serum inflammatory factors and lipoproteins were determined by ELISA and an automatic biochemical analyzer (dynamic timed scatter turbidimetry and enzymatic method) to assess the anti-inflammatory and lipid-regulating effects of Danlou tablet. ResultsIn terms of angina pectoris attacks, compared with that in the control group, the frequency of attacks in the observation group was reduced (P<0.05). In terms of endothelial injury markers, compared with the levels before treatment within the same group, the levels of endothelin-1 (ET-1), intercellular adhesion molecule-1 (ICAM-1), and vascular cell adhesion molecule-1 (VCAM-1) in the peripheral blood of the observation group were decreased (P<0.05), while the levels of nitric oxide (NO) and vascular endothelial growth factor (VEGF) were increased (P<0.05). Compared with the control group after treatment, the differences in ET-1, NO, ICAM-1, and VCAM-1 were significant (P<0.05). In terms of serum inflammatory factors, after treatment, the interleukin-6 (IL-6) level in the observation group was decreased significantly (P<0.05). Compared with the control group after treatment, the IL-6 level in the observation group was decreased significantly (P<0.01). In terms of serum lipoproteins, after treatment, the level of low-density lipoprotein cholesterol (LDL-C) in the observation group was decreased (P<0.05). After treatment, the level of high-density lipoprotein cholesterol (HDL-C) in the observation group was significantly higher than that in the control group (P<0.05). In terms of safety evaluation, no serious adverse events occurred in either group during the intervention period. ConclusionDanlou tablet applied to patients with CAS combined with CHD can improve endothelial function, reduce inflammatory indicators, alleviate symptoms, improve the quality of life of patients, and demonstrate good safety.

Decision-making aid for cancer patients is of great significance in the diagnosis and treatment for diseases. Breast cancer is one of the most common malignant tumors in women all over the world, and breast cancer patients have become the main target population for decision-aided research. Application of decision-making assistance for patients in Western countries has developed to a certain extent, while relevant research in China is still at the early stage. There are kinds of intervention forms for patients' decision aids, including traditional brochures and videos, decision aids systems, decision coaching, multidisciplinary breast cancer teams, etc. The tools for decision-making quality evaluation include the patients' awareness for decision-making, participation, decision-making conflict, decision-making satisfaction, decision-making regret, which can provide important guidance for the application of decision-making aid treatment in breast cancer patients in the future.

Objective:To summarize the experience of surgical treatment of primary liver cancer.Methods:The clinical data of 10 966 surgically managed cases with primary liver cancer, from January 1986 to December 2019 at Hepatobiliary Center, the First Affiliated Hospital of Nanjing Medical University, were retrospectively analyzed. The life table method was used to calculate the survival rate and postoperative recurrence rate. Log‐rank test was used to compare the survival process of different groups, and the Cox regression model was used for multivariate analysis. In addition, 2 884 cases of hepatocellular carcinoma(HCC) with more detailed follow‐up data from 2009 to 2019 were selected for survival analysis. Among 2 549 patients treated with hepatectomy, there were 2 107 males and 442 females, with an age of (56.6±11.1) years (range: 20 to 86 years). Among 335 patients treated with liver transplantation, there were 292 males and 43 females, with an age of (51.0±9.7) years (range: 21 to 73 years). The outcomes of hepatectomy versus liver transplantation, anatomic versus non-anatomic hepatectomy were compared, respectively.Results:Of the 10 966 patients with primary liver cancer, 10 331 patients underwent hepatectomy and 635 patients underwent liver transplantation. Patients with liver resection were categorized into three groups: 1986-1995(712 cases), 1996-2008(3 988 cases), 2009?2019(5 631 cases). The 5‐year overall survival rate was 32.9% in the first group(1986-1995). The 5‐year overall survival rate of resected primary liver cancer was 51.7% in the third group(2009‐2019), among which the 5‐year overal survival rates of hepatocellular carcinoma, intrahepatic cholangiocarcinoma and mixed liver cancer were 57.4%, 26.6% and 50.6%, respectively. Further analysis was performed on 2 549 HCC patients with primary hepatectomy. The 1‐, 3‐, 5‐, and 10‐year overall survival rates were 88.1%, 71.9%, 60.0%, and 41.0%, respectively, and the perioperative mortality rate was 1.0%. Two hundred and forty‐seven HCC patients underwent primary liver transplantation, with 1‐, 3‐, 5‐, and 10‐year overall survival rates of 84.0%, 64.8%, 61.9%, and 57.6%, respectively. Eighty‐eight HCC patients underwent salvage liver transplantation, with the 1‐, 3‐, 5‐, and 10‐year overall survival rates of 86.8%, 65.2%, 52.5%, and 52.5%, respectively. There was no significant difference in survival rates between the two groups with liver transplantation ( P>0.05). Comparing the overall survival rates and recurrence rates of primary hepatectomy (2 549 cases) with primary liver transplantation (247 cases), the 1‐, 3‐, 5‐, and 10‐year overall survival rates in patients within Milan criteria treated with hepatectomy and transplantation were 96.3%, 87.1%, 76.9%, 54.7%, and 95.4%, 79.4%, 77.4%, 71.7%, respectively ( P=0.754). The 1‐, 3‐, 5‐year recurrence rates were 16.3%, 35.9%, 47.6% and 8.1%, 11.7%, 13.9%, respectively( P<0.01). The 1‐, 3‐, 5‐, 10‐year overall survival rates in patients with no large vessels invasion beyond the Milan criteria treated with liver resection and transplantation were 87.2%, 65.9%, 53.0%, 33.0% and 87.6%, 71.8%, 71.8%, 69.3%, respectively( P=0.003); the 1‐, 3‐, 5‐year recurrence rate were 39.2%, 57.8%, 69.7% and 29.7%, 36.7%, 36.7%, respectively ( P<0.01). The 1‐, 3‐, 5‐, and 10‐year overall survival rates in patients with large vessels invasion treated with liver resection and transplantation were 62.1%, 36.1%, 22.2%, 15.0% and 62.9%, 31.8%,19.9%, 0, respectively ( P=0.387); the 1‐, 3‐, 5‐year recurrence rates were 61.5%, 74.7%, 80.8% and 59.7%, 82.9%, 87.2%, respectively( P=0.909). Independent prognostic factors for both overall survival and recurrence‐free survival rates of HCC patients treated with liver resection included gender, neoadjuvant therapy, symptoms, AST, intraoperative or postoperative blood transfusion, tumor number, tumor size, cirrhosis, macrovascular invasion, microvascular invasion, and pathological differentiation. Propensity score matching analysis of 443 pairs further showed that there was no significant difference in overall survival rate between anatomical liver resection and non‐anatomical liver resection( P=0.895), but the recurrence rate of non‐anatomical liver resection was higher than that of anatomical liver resection( P=0.035). Conclusions:In the past decade, the overall survival rate of HCC undergoing surgical treatment is significantly higher than before. For HCC patients with good liver function reservation, surgical resection can be performed first, and salvage liver transplantation can be performed after recurrence. The effect of salvage liver transplantation is comparable to that of primary liver transplantation. As for the choice of liver resection approaches, non‐anatomical resection can reserve more liver tissue and can be selected as long as the negative margin is guaranteed.

This study was aimed to analyze the bioinformatics of proteomics of rat bone marrow mesenchymal stem cells (MSCs) intervened by active principle region of Yang-Xin Tong-Mai Formula (apr-YTF). The latest versions of bioinformatics tools including DAVID (http://david.abcc.ncifcrf.gov/) and GO (http://www.geneontology.org/) were combined to assign a precise function to rat bone marrow MSCs intervened by apr-YTF. KEGG and VISANT were assigned with a precise function to rat bone marrow MSCs intervened by apr-YTF. The results showed that a total of 102 biological processes were mainly involved, with 35 cellular components and 6 molecular functions. These proteins interacted in 3 signal transduction pathways. It was concluded that the following proteins and signal transduction pathways played an important role in the process of apr-YTF inducing BMSCs differentiation into cardiomyocytes. Presenilin-1 and Presenilin-2 were in the Notch signaling pathway. And syntaxin-4 protein was in soluble N-ethylmaleimide sensitive fusion protein attachment protein (SNARE). The apr-YTF played a role on MSCs from multiple sites, with multiple links through different biological processes. The bioinformatics of proteomics can predict action mechanism of traditional Chinese medicine (TCM) from the holism concept. The validation in combination with molecularbiology was a good way for TCM modernization.
