Autophagy is mediated by multiple molecules and pathways. In cardiovascular diseases, autophagy can play a role through key signaling pathways such as phosphoinositide 3-kinase (PI3K)/protein kinase B (Akt)/mammalian target of rapamycin (mTOR), adenosine monophosphate-activated protein kinase (AMPK)/mTOR, mitogen-activated protein kinases (MAPK), p53, Wnt/β-catenin, etc. Traditional Chinese medicine (TCM) monomers for promoting blood circulation and removing blood stasis such as hydroxysafflor yellow A, ginsenoside Rb1, salidroside, ligustrin, curcumin, etc., and TCM prescription and preparations such as Huangqi baoxin decoction, Taohong siwu decoction, Tongxinluo capsule, Shuangshen ningxin capsule, Suxiao jiuxin pills, etc. can regulate autophagy through the above-mentioned key signaling pathways, thereby alleviating the progression of cardiovascular diseases.

The incidence of intrahepatic cholangiocarcinoma (ICC) continues to rise, and there are no effective drugs to treat it. The immune microenvironment plays an important role in the development of ICC and is currently a research hotspot. Icaritin (ICA) is an innovative traditional Chinese medicine for the treatment of advanced hepatocellular carcinoma. It is considered to have potential immunoregulatory and anti-tumor effects, which is potentially consistent with the understanding of "Fuzheng" in the treatment of tumor in traditional Chinese medicine. However, whether ICA can be used to treat ICC has not been reported. Therefore, in this study, sgp19/kRas, an

Rheumatoid arthritis(RA) is a widely prevalent autoimmune inflammatory disease that severely affects patients' quality of life. Currently, conventional formulations against RA have several limitations, such as nonspecificity, poor efficacy, large drug dosages, frequent administration, and systemic side effects. Nanotechnology-based drug delivery systems have emerged as a promising stra-tegy for the diagnosis and treatment of RA since nanotechnology can overcome the limitations of traditional treatments and simplify the complexity of the disease. These systems enable targeted delivery of anti-inflammatory drugs to the inflamed areas through active and passive targeting, achieving specificity to the joints, overcoming the need for increased dosage and administration frequency, and reducing associated adverse reactions. This article aimed to review nanocarrier-based drug delivery systems in the field of RA and elucidate how nanosystems can be utilized to deliver therapeutic drugs to inflamed joints for controlling RA progression. By discussing the current issues and challenges faced by nanodrug delivery systems and highlighting the urgent need for solutions, this article offers theoretical support for further research on nanotechnology-based co-delivery systems in the future.

In this experiment, the PK/PD fitting model of Chuanxiong(Chuanxiong Rhizoma) in the treatment of rheumatoid arthritis was established in the form of acupoint combined with external application gel paste. Firstly, the rheumatoid arthritis model was induced by ovalbumin, and the articular fluid of rabbits was extracted by microdialysis. The pharmacokinetic process of Chuanxiong in rabbit articular fluid was analyzed by UPLC-MS/MS, and the pharmacokinetic model was established. The pharmacodynamic effects of Chuanxiong on inflammatory factors IL-1β, TNF-α, and IL-6 were analyzed by enzyme-linked immunosorbent assay(ELISA). The pharmacodynamic model was established, and the PK/PD model was obtained by fitting the data of pharmacokinetics and pharmacodynamics. The results of pharmacokinetics showed that the concentration of ligustrolide A in the articular cavity by drug administration on classical acupoint Zusanli(ST 36) was higher than that by Yanglingquan(GB 34), which reflected the advantage of typical acupoint, while ligustrazine concentration was higher after administration through Yanglingquan than through Zusanli, which was different from the traditional acupoint theory. The results of pharmacodynamics showed that the drug had lag effect. The PK/PD model was constructed by fitting the data. When IL-1β was taken as the efficacy index, the PK/PD models of Chuanxiong in typical acupoint Zusanli group, atypical acupoint Yanglingquan group, and non-acupoint group were E=115.28C_e/(3 316.72+C_e), E=108.73C_e/(2 993.47+C_e), and E=101.34C_e/(3 028.51+C_e). When TNF-α was taken as the efficacy index, the PK/PD models of Chuanxiong in typical acupoint Zusanli group, atypical acupoint Yanglingquan group, and non-acupoint group were E=68.31C_e/(3 285.16+C_e), E=59.27C_e/(2 919.86+C_e), and E=53.61C_e/(2 862.87+C_e). When IL-6 was taken as the efficacy index, the PK/PD models of Chuanxiong in typical acupoint Zusanli group, atypical acupoint Yanglingquan group, and non-acupoint group were E=59.92C_e/(3 461.17+C_e), E=58.34C_e/(2 723.51+C_e), and E=49.17C_e/(2 862.76+C_e). The parameters showed that there were significant differences in E_(max), EC_(e50) and k_(eo). The analysis of data found that the PK/PD fitting effect of Zusanli, a typical acupoint, was the best, which proved that it was still the best site for drug administration. To sum up, it shows that there may be bidirectional selectivity between drugs and acupoints.

AIM:To observe and compare the clinical efficacy and safety of intravitreal injection of conbercept or aflibercept in the treatment of pachychoroid neovasculopathy(PNV).METHODS:Retrospective case-control study. A total of 33 patients(35 eyes)diagnosed as PNV in our hospital from February 2018 to October 2022 were divided into 14 cases(14 eyes)in conbercept group and 19 cases(21 eyes)in aflibercept group according to the treatment methods. The best corrected visual acuity(BCVA), subfoveal choroidal thickness(SFCT)and central macular thickness(CMT), injection times and clinical complications of the two groups were compared before and 1, 3 and 6mo after treatment.RESULTS:BCVA, CMT and SFCT in both groups were significantly improved after 1, 3 and 6mo of treatment(all P<0.05). During the whole follow-up period, the number of intravitreal injections in the two groups were 2(2, 3)and 2(1.5, 2)respectively, and there was no significant difference(P=0.423). No serious complications occurred during the treatment of the two groups.CONCLUSION:Both intravitreal injections of conbercept and aflibercept can treat PNV with similar therapeutic effects. The desired clinical outcome is achieved by improving the anatomy while improving visual acuity.

BACKGROUND:
Abnormal type I collagen (COL1) expression is associated with the development of many cardiovascular diseases. The TGF-beta/Smad signaling pathway and circRNAs have been shown to regulate COL1 gene expression, but the underlying molecular mechanisms are still not fully understood.
METHODS:
Gain- and loss-of-function experiments were prformed to study the effect of circZBTB46 on the expression of alpha 2 chain of type I collagen (COL1A2). Co-immunoprecipitation assay was performed to observe the interaction between two proteins. RNA immunoprecipitation assay and biotin pull-down assay were performed to observe the interaction of circZBTB46 with PDLIM5.
RESULTS:
In this study, we investigated the role of circZBTB46 in regulating COL1A2 expression in human vascular smooth muscle cells (VSMCs). We found that circZBTB46 is expressed in VSMCs and that TGF-beta inhibits circZBTB46 formation by downregulating KLF4 expression through activation of the Smad signaling pathway. CircZBTB46 inhibits the expression of COL1A2 induced by TGF-beta. Mechanistically, circZBTB46 mediates the interaction between Smad2 and PDLIM5, resulting in the inhibition of Smad signaling and the subsequent downregulation of COL1A2 expression. Furthermore, we found that the expression of TGF-beta and COL1A2 is decreased, while circZBTB46 expression is increased in human abdominal aortic aneurysm tissues, indicating that circZBTB46-mediated regulation of TGF-beta/Smad signaling and COL1A2 synthesis in VSMCs plays a crucial role in vascular homeostasis and aneurysm development.
CONCLUSIONS
CircZBTB46 was identified as a novel inhibitor of COL1 synthesis in VSMCs, highlighting the importance of circZBTB46 and PDLIM5 in regulating TGF-beta/Smad signaling and COL1A2 expression.

ObjectiveTo investigate the effects of the volatile oil of Linderae Radix on the apoptosis and autophagy of human gastric cancer cell line AGS, and to explore the regulatory role of adenosine monophosphate-activated protein kinase (AMPK)/mammalian target of rapamycin (mTOR) signaling pathway in this process. MethodThe volatile oil of Linderae Radix was extracted by steam distillation, and the effect of the volatile oil on the viability of AGS cells was detected by thiazolyl tetrazolium (MTT) colorimetry. The optimal intervention dose and time were determined according to the half maximal inhibitory concentration (IC50) for subsequent research. The blank, low, medium, and high-dose volatile oil (0, 15, 30, 60 mg·L-1) groups and the positive drug cyclophosphamide (CTX, 350 mg·L-1) group were designed. AGS cells were treated with different doses of volatile oil for 48 h. The changes in cell proliferation, cycle, and migration were measured by colony formation assay, flow cytometry, and cell scratch test, respectively. Hematoxylin-eosin (HE) staining was employed to observe the changes of cell morphology, Annexin-V/propidium iodide (PI) double staining to measure the apoptosis, and acridine orange (AO) staining to measure the autophagy level of the cells. Western blotting was employed to determine the expression of the autophagy effectors Beclin-1, p62, microtubule-associated protein 1-light chain 3 (LC3), B-cell lymphoma-2 (Bcl-2), Bcl-2-associated X protein (Bax), cleaved Caspase-3, cleaved poly ADP-ribose polymerase (PARP), adenosine monophosphate-activated protein kinase (AMPK), phosphorylated AMPK (p-AMPK), mTOR, and phosphorylated mTOR (p-mTOR). ResultCompared with the blank group, 24 h and 48 h of intervention with the volatile oil of Linderae Radix inhibited the viability of AGS cells in a concentration- and time-dependent manner (P<0.05, P<0.01). Compared with the blank group, the volatile oil decreased the cell proliferation and migration (P<0.05, P<0.01) and blocked the AGS cell cycle in G2/M phase (P<0.05, P<0.01) in a concentration-dependent manner. The cells treated with the volatile oil became spherical and smaller, with the formation of apoptotic bodies and increased apoptosis rate (P<0.05, P<0.01). As the dose of the volatile oil increased, the number of autophagosomes increased and the red fluorescence gradually enhanced, indicating the elevated level of autophagy. Compared with the blank group, different doses of volatile oil up-regulated the protein levels of Beclin-1, LC3 Ⅱ/LC3 Ⅰ, cleaved Caspase-3, cleaved PARP, Bax/Bcl-2, and AMPK (P<0.05, P<0.01) and down-regulated the protein levels of p62 and p-mTOR (P<0.05, P<0.01). ConclusionThe volatile oil of Linderae Radix induces the apoptosis and exerts the autophagy-mediated growth inhibition of AGS cells by regulating the AMPK/mTOR signaling pathway.

OBJECTIVE:
To analyze the global epidemic status of the Ebola virus disease (EVD) and assess the importation risk into China.
METHODS:
Data from World Health Organization reports were used. We described the global epidemic status of EVD from 1976-2021, and assessed and ranked the importation risk of EVD from the disease-outbreaking countries into China using the risk matrix and Borda count methods, respectively.
RESULTS:
From 1976-2021, EVD mainly occurred in western and central Africa, with the highest cumulative number of cases (14,124 cases) in Sierra Leone, and the highest cumulative fatality rate (85%) in the Congo. Outbreaks of EVD have occurred in the Democratic Republic of the Congo and Guinea since 2018. The importation risk into China varies across countries with outbreaks of disease. The Democratic Republic of the Congo had an extremely high risk (23 Borda points), followed by Guinea and Liberia. Countries with a moderate importation risk were Nigeria, Uganda, Congo, Sierra Leone, Mali, and Gabon, while countries with a low importation risk included Sudan, Senegal, and C

The concept of ethnic medicine is divided into a broad sense and a narrow sense. The broad concept refers to the traditional medicine of the Chinese nation, and the narrow concept refers to the traditional medicine of Chinese ethnic minorities. The external medicine is one of the main forms of ethnic medicine, and it is also the important content of ethnic medicine for external use, which is widely used in clinical practice. As the theory of ethnic medicine is unique, the application methods have certain characteristics, which are the key technical parts of clinical practice. However, the existing traditional Chinese medicine consensus formulation me-thods cannot meet the needs of the consensus formulation of the external ethnic medicine. Therefore, the methods suitable for expert consensus on external ethnic medicine are required. This article took Expert opinion on clinical application of Baimai Ointment as an exa-mple, and explorde a reasonable, effective, multi-dimensional, and multi-stage method to formulate expert consensus on the external ethnic medicine. In this research, three-dimensional sources of information, including ancient classics, clinical research evidence, and expert application experiences, were systematically and scientifically collected. After organization and analysis, the information was formed into comprehensive evidence. In a formal consensus meeting, part of the recommendations reached consensus. As to the issues that did not reach agreement, in-depth interviews were used to explore the reasons for the differences and resolve the disagreements. Finally, unanimous recommendations were reached. There are common problems during the formulation process of Expert opinion on clinical application of Baimai Ointment. This study is expected to provide references for the formulation of expert consensus on other external ethnic medicine.
