Objective:To explore effect of human umbilical cord mesenchymal stem cells(hUC-MSCs)on macrophage M1/M2 polarization.Methods:hUC-MSCs were co-cultured with pTHP-1 cells which were macrophage-like cells induced by PMA and tran-scriptome sequencing data were analyzed.Differentially expressed genes were screened and analyzed by GO and KEGG enrichment analysis.Effect of hUC-MSCs on pTHP-1 cells proliferation was analyzed by cell proliferation assay(CCK-8 and EdU).Flow cytometry was used to verify influence of hUC-MSCs on relative contents of inflammatory cytokine TNF-α and anti-inflammatory cytokine IL-10 in pTHP-1 cells which were interaction with LPS.Effect of hUC-MSCs on M1/M2-related molecular phenotype of pTHP-1 cells was studied by qRT-PCR and flow cytometry.Results:Transcriptome sequencing data analysis showed that M1-related genes TNF-α(P<0.05)and HLA-DRA(P<0.01)decreased to a great extent and M2-related gene ARG1(P<0.05)increased to a great extent in pTHP-1 cells after co-culture with hUC-MSCs,suggesting that hUC-MSCs inhibited macrophage M1 polarization.GO and KEGG analysis showed that these dysregulated genes regulated inflammation and immune response.hUC-MSCs inhibited proliferation of pTHP-1 cells,reduced content of TNF-α and increased content of IL-10(P<0.001).qRT-PCR and flow cytometry showed mRNA expressions of HLA-DRA(P<0.05)and CD68(P<0.01)and CD14+CD11c+M1 macrophage percentage were down-regulated,while mRNA expressions of CD163(P<0.001),CD206(P<0.001)and CD14+CD163+M2 macrophage percentage were significantly up-regulated in pTHP-1 cells after co-culture with hUC-MSCs.Conclusion:hUC-MSCs inhibit macrophage polarization to M1 and promote polariza-tion to M2 in vitro.

Objective:To explore the composition of oral microbiome in patients of long-term survival after liver transplantation, and compare the diversity and distribution of oral microbiome in liver transplant patients with or without liver cancer.Methods:This is a cross-sectional study. Clinical data of 20 patients of long-term survival after liver transplantation from Beijing Chaoyang Hospital Affiliated to Capital Medical University from July 2023 to October 2023 were continuously collected, including 13 males and 7 females, aged 55 (48, 60) years. There were eight patients with hepatocellular carcinoma (HCC) undergoing liver transplantation and 12 non-HCC liver transplant patients. Oral microbiome was analyzed by 16S rDNA gene sequencing, and the diversity analysis and LEfSe analysis were performed.Results:The top ten groups of bacteria in the HCC and non-HCC liver transplant patients were both Bacteroidota, Firmicutes, Proteobacteria, Actinobacteria, Fusobacteriota, Patescibacteria, Campylobacterota, Cyanobacteria, spirochaetota, and Aenigmarchaeota. The top ten genus levels of bacteria in the HCC and non-HCC liver transplant patients were both Haemophilus, Porphyromonas, Gemella, Fusobacterium, Actinomyces, Prevotella, Rothia, Streptococcus, Neisseria. By LEfSe analysis, we found the enrichment of Flavobacteriales, Flavobacteriaceae, Capnocytophaga, Mogibacterium_timidum, Capnocytophaga_leadbetteri, Campylobacter_showae in the HCC group, while the enrichment of Veillonella_atypica, Prevotella_histicola in the non-HCC group.Conclusion:The main microbiome was similar between HCC and non-HCC liver transplant patients, but there were also some differences in microbiome communities.

Prostate cancer remains the second most common malignancy in men worldwide, is a global health issue, and poses a huge health burden. Precision medicine provides more treatment options for prostate cancer patients, but its popularity, drug resistance, and adverse reactions still need to be focused on. Chinese herbal medicines (CHMs) have been widely accepted as an alternative therapy for cancer, with the advantages of multiple targets, multiple pathways, and low toxicity. We searched the experimental research and clinical practice of CHMs for prostate cancer treatment published in PubMed, Embase, and Web of Science in the last five years. We found five CHM formulas and six single CHM extracts as well as 12 CHM-derived compounds, which showed induction of apoptosis, autophagy, and cell cycle arrest, suppression of angiogenesis, proliferation, and migration of prostate cancer cells, reversal of drug resistance, and enhancement of anti-tumor immunity. The mechanisms of action include the PI3K/Akt/mTOR, AR, EGFR and Wnt/β-catenin signaling pathways, which are commonly implicated in the development of prostate cancer. We also summarized the advantages of CHMs in patients with hormone-sensitive and castration-resistant prostate cancer and provided ideas for their further experimental design and application.

The most common subtype of lung cancer is non-small cell lung cancer (NSCLC), which has a poor prognosis and seriously threatens the health of human beings. The multidisciplinary comprehensive treatment model has gradually become the mainstream of NSCLC treatment. Traditional Chinese medicine (TCM) can be used effectively either as an adjunctive therapy or alone throughout the NSCLC therapy, which has a significant impact on survival, quality of life, and reduction of toxicity. Therefore, this paper reviewed the theoretical basis, the latest clinical application, and combined treatment mechanisms in order to explore the advantage stage of TCM treatment and the synergistic therapeutic mechanisms.

Hepatocellular carcinoma (HCC) is a common malignant tumor of the liver characterized by a high incidence rate, rapid progression, and poor prognosis. In recent years, it has been found that non-coding RNA (ncRNA) participates in the regulation of tumor immunity in tumor microenvironment (TME) and in turn affects the biological behavior of HCC. This article briefly describes the regulatory effect of ncRNA on immune cells in TME and introduces the potential value of ncRNA in the diagnosis and treatment of HCC, in order to provide potential diagnostic and treatment strategies for HCC.

Objective:To investigate the efficacy and safety of intravenous thrombolysis with recombinant tissue plasminogen activator (rt-PA) in patients with maintenance hemodialysis (MHD) and acute ischemic stroke.Methods:The clinical data of 235 patients with acute ischemic stroke receiving MHD were collected in our hospital from March 2018 to October 2021. According to the treatment methods chosen by themselves, these patients were divided into control group ( n=70, only receiving standardized secondary stroke prevention), rt-PA low-dose group ( n=85, receiving rt-PA intravenous thrombolysis, 0.6 mg/kg) and rt-PA standard-dose group ( n=80, receiving rt-PA intravenous thrombolysis, 0.9 mg/kg). The effective rate 24 h after treatment, good efficacy rate 7 d after treatment, and good prognosis rate and mortality 90 d after treatment were used to evaluate the effectiveness. The incidences of intracranial hemorrhage, symptomatic intracranial hemorrhage, and severe extracranial hemorrhage 90 d after treatment were used to evaluate the safety. Results:There was no statistical difference in the good prognosis rate 90 d after treatment among the rt-PA low-dose group, the rt-PA standard-dose group and the control group (71.8%, 68.8%, and 64.3%; P>0.05), but the effective rate 24 h after treatment and good efficacy rate 7 d after treatment in the rt-PA low-dose group and rt-PA standard-dose group (44.7%, 57.7%; 46.3%, 62.5%) were both significantly higher than those in the control group (27.1%, 38.6%; P<0.05). The mortality 90 d after treatment in the rt-PA low-dose group (7.1%) was significantly lower than that in the rt-PA standard-dose group (22.5%) and control group (21.4%, P<0.05). The incidences of intracranial hemorrhage and symptomatic intracranial hemorrhage in the rt-PA low-dose group (8.2%, 3.5%) were significantly lower than those in the rt-PA standard-dose group (22.5%, 16.3%; P<0.05), and the incidences of extracranial complications and gastrointestinal bleeding (5.9%, 1.2%) were significantly lower than those in the rt-PA standard-dose group (18.8%, 10.0%; P<0.05). Conclusion:Intravenous thrombolytic therapy with 0.6 mg/kg rt-PA is recommended for acute ischemic stroke patients receiving MHD.

Objective:To analyze the plasma levels of soluble immune checkpoint molecules in patients with primary liver cancer and their prognostic significance.Methods:The levels of sCD28, sCD80, sCD137, sCD27, sGITR, sTIM3, sCTLA4, sHVEM, IDO, sLAG3, sBTLA, sPD1, sPDL1 and sPDL2 in plasma samples of 58 patients with primary liver cancer and 30 healthy controls were detected by liquid chip technology and compared between different groups. The relationship between the plasma levels of soluble immune checkpoint molecules and tumor recurrence was analyzed.Results:The levels of sCD28 and sCD80 were higher in patients in Barcelona Clinic Liver Cancer (BCLC) stage 0/A and B than in healthy controls and patients in BCLC-C stage ( P<0.05). However, the levels of sCD27 and sHVEM in BCLC-C patients were significantly lower than those in BCLC-0/A and BCLC-B patients, and even lower than healthy control group. The levels of sCD137, IDO and sPD1 in BCLC-0/A and BCLC-B patients were higher than those in healthy controls. The levels of sPDL1 and sPDL2 in different BCLC stages were all higher than those in healthy controls, and maintained at high level in the three stages, but there was no significant difference between different stages. After 24 months of interventional treatment, the preoperative sCD28 level was lower in patients with recurrent tumor recurrence than in patients without recurrence ( t=2.843, P=0.007). The optimal cut-off value of sCD28 based on the receiver operating characteristic (ROC) curve for predicting tumor recurrence was 101.42 pg/ml and the area under the ROC curve was 0.771 (95%CI: 0.611-0.931) with a sensitivity of 0.889 and a specificity of 0.666. The cumulative recurrence rate in patients with high sCD28 level (≥101.41 pg/ml) was 57.9% at 24 months after surgery, which was lower than the rate (95.5%) in patients with low sCD28 level (<101.41 pg/ml). The difference in the cumulative recurrence rate between the two groups was statistically significant (χ 2=15.777, P=0.000). Conclusions:The expression patterns of soluble immune checkpoint molecules varied in patients at different stages of primary liver cancer, suggesting that there were differences in their immune status and sCD28 could be used as a prognostic marker for postoperative recurrence of liver cancer.

The treatment rules of point selection and treatment principles for treating chronic fatigue syndrome (CFS) can be divided into three categories: regulating and replenishing, invigorating original yang and regulating zang-fu organs. The mechanism of moxibustion includes improving gut microbiota imbalance, regulating immune cell imbalance and correcting endocrine dysfunction. The moxibustion methods include ginger-partitioned moxibustion, thunder-fire moxibustion, warm acupuncture, and governor moxibustion. Acupuncture points such as Shenque (RN8), Guanyuan (RN4), Qihai (RN6), Zusanli (ST36), Baihui (DU20), Yongquan (KI1) and back-shu points are often selected to exert anti-chronic fatigue effects.

Root position plays an important role in healthy, stable, and aesthetic orthodontic treatment. In the past, two-dimensional radiographic images were used to assess the accuracy and precision of tooth root positions. In recent years, the use of cone beam CT (CBCT) and its reconstructed images to measure the three-dimensional spatial position and angle of root position has become mainstream. The root position is mainly described by measuring the relationship between the root and adjacent structures in the buccolingual, vertical, and mesiodistal directions as well as the root angle. The thickness of the alveolar bone on the buccolingual side of the root represents the buccolingual position, the vertical height in the alveolar bone and the relationship between apex and maxillary sinus represents the vertical position, the interroot alveolar bone thickness represents the mesiodistal position of the root, and the root angle is mostly based on incisal mandibular plane angle, angulation, torque, and other angles in the traditional two-dimensional measurement. Fitting CBCT and digital model data can be used to monitor the relationship between root and alveolar bone during orthodontic treatment, but a more comprehensive, standardized three-dimensional tooth root position measurement method is required to make full use of the root data provided by CBCT to study the relative optimal position of the tooth root at different anatomical levels, which combines with computer technology to optimize the digital design of orthodontic diagnosis and treatment.
