Atherosclerosis is a complex pathological condition resulting from lipid deposition， chronic inflammatory responses， and fibrosis， with a prolonged disease course and multifactorial etiology. Based on the traditional Chinese medicine （TCM） theory of accumulation syndrome， atherosclerosis can be classified under this category， with its pathogenesis involving phlegm， blood stasis， deficiency， and accumulation. This paper proposed a stage-based intervention strategy using the four therapeutic principles of "attacking， supplementing， dispersing， dissipating"， and divided into six stages based on the pathological progression， including the stage of accumulation before formation， the stage of accumulation already formed， the stage of nucleus accumulation， the stage of nucleus accumulation decay， the stage of nucleus accumulation consolidation， and the stage of severe stenosis of nucleus. At different stages， the intervention focuses on reinforcing healthy qi and consolidating the root， tonifying the kidneys and spleen， dispersing and removing turbidity， removing phlegm stagnation， promoting qi circulation， dispersing accumulations and removing stasis， attacking accumulation and expelling stasis， directing the turbid downward and dispersing accumulation， and treatment would be adjusted based on specific symptoms， which provides a theoretical framework for the prevention and treatment of atherosclerosis with TCM.

Paroxysmal atrial fibrillation can be attributed to the category of xinji （palpitations） and zhangchong （severe palpitations） in traditional Chinese medicine， and its onset has the characteristics of urgency， change， and movement， which is similar to the characteristics of diseases induced by wind pathogen. It is believed that the internal movement of wind pathogen runs through the whole course of this disease， and palpitations due to wind as the direct pathogenesis. Palpitations caused by wind pathogen showed different characteristics of deficiency and excess pattern. In the acute exacerbation period， excess wind is the main cause of disease. For excessive heat generating wind， the treatment is to clear the liver and extinguish wind by self-modified Lingxia Qinggan Decoction （羚夏清肝汤）； for blood stasis generating wind， the treatment is to remove blood stasis and stop wind by self-modified Yandan Limai Decoction （延丹理脉汤）； for phlegm-heat accumulation with wind， the treatment is to dissolve phlegm and eliminate wind by self-modified Lianlou Danxing Decoction （连蒌胆星汤）. In the prolonged recovery period， deficiency wind is more common. For stirring of wind due to yin deficiency， the treatment is to nourish yin and extinguish wind by self-modified Zaoshao Zhenzhu Deoction （枣芍珍珠汤）； for spleen deficiency generating wind， the treatment is to strengthen spleen and nourish wind by self-modified Shenying Dingji Deoction （参英定悸汤）. Clinical prescriptions closely follow the characteristics of wind， weigh the changes of deficiency and excess， tailor with the patterns， and regulate qi and blood of the zang-fu organs， in order to extinguish wind and arrest convulsion.

Objective To investigate the regulatory role of miR-26b-3p in proliferation,migration and invasion of glioma.Methods The expressions of miR-26b-3p and cAMP-responsive element binding protein 1(CREB1)in gliomas of different pathological grades were detected with RT-qPCR and Western blotting.Bioinformatic methods were used to analyze the target sequence of miRNA-26b-3p binding to CREB1,and dual luciferase gene reporter experiment was performed to explore the mechanism for targeted regulation of CREB1 by miR-26b-3p.Glioma U251 cells were treated with miR-26b-3p mimic or inhibitor,and the changes in CREB1 expression and cell proliferation,migration,invasion and apoptosis were determined with Western blotting,CCK-8 assay,wound healing assay,Transwell assay,and flow cytometry.Results The expression of miR-26b-3p decreased while CREB1 expression increased significantly as the pathological grade of gliomas increased(P<0.05).Dual luciferase gene reporter experiment confirmed that CREB1 was a downstream target of miR-26b-3p.Inhibition of miR-26b-3p significantly upregulated the expression of CERB1,suppressed apoptosis and promoted proliferation and invasion of glioma cells,and overexpression of miR-26b-3p produced the opposite effects(P<0.05).Conclusion MiR-26b-3p regulates CREB1 expression to modulate apoptosis,proliferation,migration and invasion of glioma cells,thereby participating in tumorigenesis and progression of glioma.

OBJECTIVE To explore the effects and potential mechanism of veratramine （VTM） on the proliferation of human glioblastoma U251 cells. METHODS The network pharmacology methods were adopted to screen the targets of ferroptosis related to the effects of VTM on glioblastoma， and to conduct gene ontology and Kyoto Encyclopedia of Genes and Genosomes enrichment analysis. Using U251 cells as the object， CCK-8 assay， the observation of cell morphological changes， DCFH-DA fluorescence probe method， FerroOrange fluorescence probe method and Western blot assay were used to validate the inhibitory effects of VTM on U251 cell proliferation and its possible mechanism. RESULTS Totally 462 targets of ferroptosis related to the effects of VTM on glioblastoma were screened out； they mainly enriched in biological processes such as oxidative stress and apoptosis， and cellular components such as cytoplasmic vesicles and mitochondrial membranes； they affected molecular functions such as iron ion （Fe2+） binding and DNA transcription processes， as well as iron death and phosphoinositide 3-kinase/protein kinase B signaling pathways. VTM with 40， 60， 80， 100， 120 and 140 μmol/L could significantly reduce the cell survival rate （P＜ 0.01）； VTM with 40， 80 and 120 μmol/L could cause cell atrophy and nuclear fragmentation， significantly inhibit the clone formation， increase the levels of intracellular reactive oxygen species （ROS） and Fe2+ levels， increase the expressions of nuclear factor-erythroid 2-related factor 2 （Nrf2） and heme oxygenase 1 （HO-1） protein to different extents， while down-regulate the expression of glutathione peroxidase 4 （GPX4） protein （P＜0.05 or P＜0.01）. CONCLUSIONS VTM can inhibit the proliferation of U251 cells， and promote the accumulation of intracellular ROS and Fe2+， thus inducing ferroptosis； its mechanism might be related to the regulation of the Nrf2/HO-1/GPX4 signaling pathway.

Lipophagy, the selective engulfment of lipid droplets (LDs) by autophagosomes for lysosomal degradation, is critical to lipid and energy homeostasis. Here we show that the lipid transfer protein ORP8 is located on LDs and mediates the encapsulation of LDs by autophagosomal membranes. This function of ORP8 is independent of its lipid transporter activity and is achieved through direct interaction with phagophore-anchored LC3/GABARAPs. Upon lipophagy induction, ORP8 has increased localization on LDs and is phosphorylated by AMPK, thereby enhancing its affinity for LC3/GABARAPs. Deletion of ORP8 or interruption of ORP8-LC3/GABARAP interaction results in accumulation of LDs and increased intracellular triglyceride. Overexpression of ORP8 alleviates LD and triglyceride deposition in the liver of ob/ob mice, and Osbpl8-/- mice exhibit liver lipid clearance defects. Our results suggest that ORP8 is a lipophagy receptor that plays a key role in cellular lipid metabolism.

Objective To explore the application of cluster nursing mode in perioperative period of elderly patients with hip fracture.Methods A retrospective cohort study design was used.Through convenience sampling method,50 elderly patients admitted to the hospital for hip fractures from January 2018 to December 2019 were selected as the control group.Meanwhile,47 elderly patients admitted to hospital for hip fractures from January 2020 to December 2021 were selected as the experimental group.The experimental group received cluster nursing,while the control group received routine nursing measures.The outcomes compared between the 2 groups included the effective rate of pain intervention,functional exercise compliance,and the incidence of complications.Results The effective rate of pain intervention(χ2=5.922,P=0.015)and functional exercise compliance(χ2=9.685,P= 0.008)in the experimental group were higher than those in the control group.The number of perioperative complications(χ2=7.600,P=0.006)in the experimental group were lower than those in the control group.Conclusion The application of cluster nursing mode in the perioperative period of elderly patients with hip fractures can effectively control pain,improve functional exercise compliance,and reduce complications.

Objective:To preliminarily analyze the expression of angiotensin-converting enzyme 2 (ACE2) and to investigate its potential regulatory mechanism in chronic rhinosinusitis with nasal polyps (CRSwNP).Methods:Patients underwent nasal endoscopic surgery in the Third Affiliated Hospital of Sun Yat-sen University from February 2020 to May 2021 were selected, including 17 males and 6 females, aging from 23 to 66 years old. Expression of ACE2 was evaluated via immunohistochemical staining in controls with non-chronic rhinosinusitis, non-eosinophilic CRSwNP (non-ECRSwNP), and eosinophilic CRSwNP (ECRSwNP) tissue, respectively. Correlations between ACE2 and the indicated Th1/Th2-related cytokines (IFN-γ, IL-4, IL-5, IL-13, IL-25, IL-33, TSLP and periostin) were analyzed based on GSE72713 dataset. Protein-protein interaction (PPI) network was constructed via string database, immune infiltration of GSE72713 dataset was evaluated using cibersort algorithm. ACE2 was comprehensively analyzed by microRNA regulatory network, gene set enrichment analysis (GSEA) and pharmacological analysis. Statistical analysis was performed using GraphPad 7.0 and SPSS 20.0 software.Results:ACE2 was up-regulated in non-ECRSwNP compared with ECRSwNP. Microarray analysis showed that ACE2 was positively correlated with IFN-γ while inversely correlated with IL-5, IL-13 and periostin significantly. Analysis of immune infiltration suggested that ACE2 expression correlated positively with the number of M1 macrophage while negatively with M2 macrophage. GSEA demonstrated that interferon-related signaling pathways were up-regulated in non-ECRSwNP, and miRNA-200B/miRNA-200C/miRNA-429 pathways targeting ACE2 were enriched in ECRSwNP. Results of pharmacological analysis indicated that ampicillin was able to promote the expression of ACE2 whereas acetaminophen could down regulated the expression of ACE2.Conclusion:Expression pattern of ACE2 is varied in non-ECRSwNP and ECRSwNP, which may be related to the different infiltration of indicated cytokines and different regulatory pathways of miRNA.

Objective:To investigate the prognostic factors of Siewert type Ⅱ and Ⅲ adenocarcinoma of esophagogastric junction (AEG) after radical resection with different surgical approaches.Methods:The retrospective case-control study was conducted. The clinicopathological data of 442 patients who were admitted to Tianjin Medical University Cancer Institute and Hospital from February 2003 to July 2011 were collected. There were 362 males and 80 females, aged from 21 to 85 years, with a median age of 64 years. Patients underwent radical resection of AEG. Observation indicators: (1) surgical situations; (2) follow-up; (3) progrostic factors analysis of AEG after radical resection; (4) survival of patients after radical resection of AEG via abdominal approach; (5) survival of patients after radical resection of AEG via thoracoabdominal approach; (6) survival of patients after radical resection of Siewert type Ⅱ type AEG; (7) survival of patients after radical resection of Siewert type Ⅲ AEG. Follow-up using outpatient examination and telephone interview was performed to detect postoperative survival of patients up to June 2018. Measurement data with skewed distribution were described as M (range). Count data were expressed as absolute numbers or percentages. Kaplan-Meier method was used to calculate survival rates and draw survival curves, and Log-rank test was used for survival analysis. Univariate analysis was conducted using the Kaplan-Meier method. Multivariate analysis was conducted using the COX proportional hazard model. Results:(1) Surgical situations: 442 patients underwent radical resection of AEG, including 204 via abdominal approach and 238 via thoracoabdominal approach. There were 391 patients with D 2 lymphadenectomy and 51 with D 2+ lymphadenectomy. (2) Follow-up: 442 patients were followed up for 8-162 months, with a median follow-up time of 37 months. All the 442 patients survived for 2-156 months, with a median survival time of 31 months. The 1-, 3-, 5-year overall survival rates were 79.2%, 42.0%, 30.0%, respectively. (3) Prognostic factors analysis of AEG after radical resection: results of univariate analysis showed that tumor diameter, Lauren type, pathological T staging, pathological N staging, pathological TNM staging, lymphatic vessel invasion, and soft tissue infiltration were related factors for prognosis of patients after radical resection of Siewert type Ⅱ and Ⅲ AEG ( χ2=4.028, 4.885, 19.435, 17.014, 34.449, 9.707, 11.866, P<0.05). Results of multivariate analysis showed that pathological TNM staging, lymphatic vessel invasion, and soft tissue infiltration were independent influencing fators for prognosis of patients after radical resection of Siewert type Ⅱ and Ⅲ AEG ( hazard ratio=1.255, 0.486, 1.454, 95% confidence interval: 1.024-1.539, 0.325-0.728, 1.096-1.928, P<0.05). (4) Survival of patients after radical resection of AEG via abdominal approach: of the 204 patients undergoing radical resection of AEG via abdominal approach, the 1-, 3-, 5-year survival rates were 83.6%, 50.4%, 37.8% for 121 patients with Siewert type Ⅱ AEG, respectively, versus 72.0%, 39.3%, 31.8% for 83 patients with Siewert type Ⅲ AEG, showing no significant difference in the survival between the two groups ( χ2=1.854, P>0.05). (5) Survival of patients after radical resection of AEG via thoracoabdominal approach: of the 238 patients undergoing radical resection of AEG via thoracoabdominal approach, the 1-, 3-, 5-year survival rates were 79.6%, 38.8%, 23.8% for 183 patients with Siewert type Ⅱ AEG, respectively, versus 79.1%, 37.6%, 29.3% for 55 patients with Siewert type Ⅲ AEG, showing no significant difference in the survival between the two groups ( χ2=0.215, P>0.05). (6) Survival of patients after radical resection of Siewert type Ⅱ AEG: of the 304 patients with Siewert typeⅡAEG, the postoperative 1-, 3-, 5-year survival rates were 83.6%, 50.4%, 37.8% for 121 patients undergoing radical resection of AEG via abdominal approach, respectively, versus 79.6%, 38.8%, 23.8% for 183 patients undergoing radical resection of AEG via thoracoabdominal approach, showing no significant difference in the survival between the two groups ( χ2=2.406, P>0.05). (7) Survival of patients after radical resection of Siewert type Ⅲ AEG: of the 138 patients with Siewert type Ⅲ AEG, the postoperative 1-, 3-, 5-year survival rates were 72.0%, 39.3%, 31.8% for 83 patients undergoing radical resection of AEG via abdominal approach, respectively, versus 79.1%, 37.6%, 29.3% for 55 patients undergoing radical resection of AEG via thoracoabdominal approach, showing no significant difference in the survival between the two groups ( χ2=0.640, P>0.05). Conclusions:Pathological TNM staging, lymphatic vessel invasion, and soft tissue infiltration are independent fators for prognosis of patients after radical resection of Siewert type Ⅱ and Ⅲ AEG. Siewert types and surgical approach are not related factors for prognosis of patients after radical resection of AEG. There is no significant difference in the survival between patients with different Siewert types of AEG undergoing radical resection via different surgical approaches.
