Immunotherapy has emerged as a revolutionary approach to treat immune-related diseases. Dendritic cells (DCs) play a pivotal role in orchestrating immune responses, making them an attractive target for immunotherapeutic interventions. Modulation of gene expression in DCs using genome editing techniques, such as the CRISPR-Cas system, is important for regulating DC functions. However, the precise delivery of CRISPR-based therapies to DCs has posed a significant challenge. While lipid nanoparticles (LNPs) have been extensively studied for gene editing in tumor cells, their potential application in DCs has remained relatively unexplored. This study investigates the important role of cholesterol in regulating the efficiency of BAMEA-O16B lipid-assisted nanoparticles (BLANs) as carriers of CRISPR/Cas9 for gene editing in DCs. Remarkably, BLANs with low cholesterol density exhibit exceptional mRNA uptake, improved endosomal escape, and efficient single-guide RNA release capabilities. Administration of BLAN_mCas9/gPD-L1 results in substantial PD-L1 gene knockout in conventional dendritic cells (cDCs), accompanied by heightened cDC1 activation, T cell stimulation, and significant suppression of tumor growth. The study underscores the pivotal role of cholesterol density within LNPs, revealing potent influence on gene editing efficacy within DCs. This strategy holds immense promise for the field of cancer immunotherapy, offering a novel avenue for treating immune-related diseases.

Abstract Liver metastasis is one of the most common complications of advanced lung cancer and an important factor influencing patient prognosis and survival. Currently, there are limited effective treatment options for lung cancer patients with liver metastasis, leading to short survival and poor prognosis. In-depth studies of the related molecular mechanisms are crucial for advancing clinical translation and optimizing therapeutic strategies. In recent years, more and more studies of the mechanisms of liver metastasis in lung cancer have performed, particularly in areas such as the roles of different proteins, cell-cell interactions, and changes in the tumor microenvironment. This review summarizes the current understanding of the basic process of lung cancer liver metastasis, regulatory proteins, signaling pathways, tumor microenvironment changes, and clinical treatment progress. Emerging evidence highlights the critical involvement of TGF-β/smad signaling pathway and integrin family proteins in promoting lung cancer liver metastasis. In the tumor microenvironment, various cell types including mononuclear phagocytes, fibroblasts, and hepatocytes contribute to this metastatic process. Clinically, the combination of immunotherapy with chemotherapy, radiotherapy, and antiangiogenic therapy has shown potential to improve treatment outcomes. Furthermore, targeted therapy against specific pathways, proteins, and cells within the tumor microenvironment, as well as the integration of multiple treatment modalities, holds promise for becoming effective strategies in the future clinical management of lung cancer liver metastasis.

Objective:To explore the acupoint selection law of acupuncture and moxibustion in the treatment of broca aphasia after stroke.Methods:RCT articles about acupuncture and moxibustion treatment for broca aphasia after stroke were retrieved from CNKI, VIP, Wanfang Data, China Medical Journal Full-text Database, SinoMed, PubMed, Web of Science and Embase database from the establishment of the databases to May 31, 2024. Excel 2021, SPSS Statistics 27.0, SPSS Modeler 18.0 and Cytoscape 3.9.1 software were used to analyze the frequency of acupoint, clustering, association rules and core co-occurrence network.Results:A total of 87 articles were included, involving 100 acupuncture and moxibustion prescriptions and 101 acupoints/acupoint area, involving 6 types, including Lianquan (CV 23) (35 times), Jinjin (EX-HN12) (35 times) and Yuye (EX-HN13) (34 times). The selected acupoints were mainly distributed in the head, face, neck and lower limbs, and the meridians were mainly Governor Vessel and Conception Vessel; the specific acupoints were mainly original acupoints, followed by collaterals acupoints, and scalp acupuncture was used most frequently in special acupuncture (88 times). According to the clustering analysis of high-frequency acupoints/acupoint area, there were five effective groups, such as "Jinjin (EX-HN12)-Yuye (EX-HN13)-Lianquan (CV 23)-Baihui (GV 20)-Yamen (GV 15)". The core co-occurrence network analysis showed that the acupoints used most frequently were Lianquan (CV 23) and Jinjin (EX-HN12), and the highest correlation between the two acupoints was Jinjin (EX-HN12)-Yuye (EX-HN13).Conclusions:Acupuncture and moxibustion for the treatment of broca aphasia after stroke is often based on "awakening the brain as the outline, benefiting the marrow as the foundation, and resuscitation". Under the guidance of the theory of Zang-fu meridians and collaterals, through dredging the meridians and collaterals, tonifying the brain and opening and closing the sound, the recovery of language function can be achieved.

ObjectiveTo investigate the relationship between the composition of traditional Chinese medicine (TCM) and depression/anxiety/sleep disturbances (D/A/S) in patients with chronic pain.MethodsThis cross-sectional study was conducted at 13 tertiary hospitals across China, enrolling patients who experienced chronic pain between November 2023 and May 2024. The Patient Health Questionnaire-9, Generalized Anxiety Disorder-7, Pittsburgh Sleep Quality Index, and TCM constitution categories were used to assess the patients. The association between the TCM constitution and the D/A/S ratio was analyzed using multivariable logistic regression.ResultsA total of 1107 patients (63.2% women) were analyzed. Compared with those with a balanced constitution, patients who had qi-deficiency and yin-deficiency were at a higher risk of depression. Qi-deficiency and yin-deficiency were associated with anxiety. Sleep disturbances were common in patients with qi-deficiency constitution (odds ratio [OR]: 2.32, 95% confidence interval [CI]: 1.42–3.81), yang-deficiency constitution (OR: 1.94, 95% CI: 1.26–2.98), yin-deficiency constitution (OR: 2.03, 95% CI: 1.24–3.32), blood stasis constitution (OR: 2.07, 95% CI: 1.01–4.22), and qi-stagnation constitution (OR: 2.66, 95% CI: 1.35–5.25).ConclusionIn patients with chronic pain, specific TCM constitutions may be associated with D/A/S. Further longitudinal studies are needed to clarify the potential causal relationships between TCM constitution types and these conditions.

ObjectiveThis study aimed to evaluate the clinical efficacy of Ruyi Zhenbaowan（RYZBW）in the treatment of initial and early knee osteoarthritis （KOA） through a prospective multicenter，randomized，double-blind，and placebo-parallel controlled trial. MethodFrom October 13^th， 2021 to December 25^th， 2021， 240 KOA subjects meeting the acceptance criteria were enrolled in 15 sub-centers including Wangjing Hospital， Chinese Academy of Chinese Medical Sciences， and they were randomly divided into observation group and control group， with 120 cases in each group. The intervention measures for the observation group were RYZBW + health education， and the intervention measures for the control group were RYZBW placebo + health education. The intervention period in both groups was four weeks， and they were followed up for four weeks after the intervention. The primary outcome measure was the total score of Western Ontario and McMaster University Osteoarthritis Index score （WOMAC score）， and the secondary outcome measures were the response rate of visual scale （VAS） pain score， WOMAC sub item scores （joint pain， joint stiffness， and joint function）， quality of life （SF-12） score， and traditional Chinese medicine （TCM） syndrome score. Result（1） Efficacy evaluation. The marginal model results showed that the observation group was better than the control group in improving the WOMAC total score and WOMAC pain score in the treatment of KOA with RYZBW， and the difference was statistically significant （P<0.05）. There was no significant difference between the two groups in improving VAS score response rate， WOMAC function score， WOMAC stiffness score， SF12-PCS （quality of life-physical health） score， SF12-MCS （quality of life-mental health） score， and TCM syndrome score. （2） Subgroup analysis. ① In terms of VAS score response rate， the response rate of the observation group was higher than that of the control group for subjects with baseline VAS score of （4， 5］， and the difference was statistically significant （P<0.05）. ② In terms of TCM syndrome score， for subjects aged ［56， 60］ and ［61， 65］， the decrease in total TCM syndrome score in the observation group was better than that in the control group， and the difference was statistically significant （P<0.05）. ConclusionTibetan medicine RYZBW has good clinical efficacy in improving WOMAC total score， VAS score response rate， WOMAC pain score， WOMAC function score， and TCM syndrome score for patients with initial and early KOA， which can fill the lack of Tibetan medicine RYZBW in the treatment of KOA and make a demonstration study for the inheritance and development of ethnic medicine.

Objective:To analyze the acupoint selection law in treating insomnia with warming-needle moxibustion using data mining technology.Methods:The clinical research literature on warming-needle moxibustion in treating insomnia was retrieved from the databases of CNKI, VIP, Wanfang Data, China Medical Journal Full-text Database, SinoMed, PubMed from the establishment of the databases to June 30, 2023. Acupuncture prescriptions were extracted and a database was established. Descriptive analysis was carried out on the intervention measures, the number of moxibustion numbers, the total effective rate, and the relevant information of acupoint selection. Clustering analysis and association rule analysis by using SPSS Statistics 26.0, SPSS Modeler 18.0 were performed on the high-frequency acupoints used in body acupuncture and warming acupuncture, respectively.Results:A total of 67 articles about warming-needle moxibustion for insomnia were included. The main intervention was single warming-needle moxibustion, followed by combined auricular acupuncture. Moxibustion with moxa sticks of 1 to 2 cm in length was often used. The total effective rate was mostly between 92% and 94%. A total of 85 prescriptions were obtained, involving 55 acupoints (569 times in frequency), among which Baihui (DU 20) (55 times), Shenmen (HT 7) (54 times) and Sanyinjiao (SP 6) (45 times) were widely used. The selected acupoints were mainly distributed on the head, face, back and waist, and the affiliated meridians were mainly bladder meridian, Governor Vessel and heart meridian. The specific acupoints were mainly crossing points, followed by back-shu acupoints. Clustering analysis of high-frequency acupoints obtained three effective groups, including "Xinshu (BL 15)- Pishu (BL 20) - Shenshu (BL 23) - Ganshu (BL 18)", etc. Baihui (DU 20) and Shenmen (HT 7) were the most relevant acupoint combinations. A total of 44 acupoints (frequency 272 times) were involved in the selection of warming acupuncture, among which Sanyinjiao (SP 6) (32 times), Xinshu (BL 15) (23 times) and Pishu (BL 20) (23 times) were more frequently used. Clustering analysis of high-frequency acupoints obtained three effective groups, including "Xinshu (BL 15)- Pishu (BL 20) - Shenshu (BL 23) - Ganshu (BL 18)", etc. Pishu (BL 20) and Xinshu (BL 15) were the most relevant acupoint combinations.Conclusions:Warming-needle moxibustion for the treatment of insomnia focuses on the application of acupoints on the bladder meridian on the back and waist, cooperates with the selection of acupoints on the head and face, and attaches importance to the application of intersection points in specific acupoints. The selection of acupoints by warming-needle moxibustion is mainly based on the back-shu acupoints of zang-fu organs, which plays the role of balancing yin and yang, regulating zang-fu organs, tonifying deficiency and tranquilizing mind to help sleep.

Objective To investigate the effect of fluid shear(FS)on apoptosis of glomerular epithelial cells(GECs)and the role of Piezo 1 protein in it.Methods GECs(glomerular epithelial cells)of SD rat were cul-tured.Fluid shear stimulation was simulated by a Flexcell-T5000 tensiometer.Apoptosis level was detected by flow cytometry.The expression of Piezo 1 proteins in GECs was detected by immunofluorescence staining.The activating of Piezo 1 channels by fluid shear was observed using Ca2+indicator(Cal-590 AM).The effect of Piezo 1 on apop-tosis in GECs was analyzed after modulating the function or expression of Piezo 1 protein using the chemical activa-tor Yoda1,the inhibitor GsMtx 4 was regulated by lentivirus Lv-shPiezo 1.Results Compared with the blank controlgroup,apoptosis increased in the fluid shear group(P＜0.05).The rate of apoptosis increased with the enhancing of fluid shear strength;Piezo 1 was commonly expressed in GECs.Fluid shear activated Piezo 1 chan-nel and enhanced expression of Piezo 1.The agonist Yoda1 promoted the apoptosis of GECs GsMtx 4 inhibited the apoptosis induced by fluid shear.Lv-shPiezo 1 knocked down the expression of Piezo 1 in GECs and the apoptosis rate of GECs in the knockdown group was reduced as compared to that in the control group and Lv-Ctrl group(P＜0.05).Conclusions Fluid shear may promote apoptosis of GECs by activation of Piezo 1 and by enhancing expression of Piezo 1.
