ObjectiveTo observe the clinical efficacy and safety of Zhuyuwan in the treatment of hyperlipidemia. MethodsIn this study， hyperlipidemia patients treated in the Hospital of Chengdu University of Traditional Chinese Medicine （TCM） from September 2022 to December 2023 were randomly assigned into a control group and an observation group. Finally， 162 valid cases were included， encompassing 74 cases in the control group and 88 cases in the observation group. The control group was treated with atorvastatin calcium tablets， and the observation group with atorvastatin calcium tablets + Zhuyuwan extract granules. Both groups were treated for 8 weeks. The efficacy in terms of blood lipid level recovery， blood lipid levels， TCM syndrome distribution， efficacy in terms of TCM syndrome， and TCM symptom scores were compared between the two groups as well as between before and after treatment. Liver and kidney functions were monitored for safety assessment. ResultsIn terms of blood lipid level recovery， the total response rate in the observation group was 86.36% （76/88） and that in the control group was 86.49% （64/74）， with no statistically significant difference between the two groups. After treatment， both groups showed declines in levels of triglyceride （TG）， total cholesterol （TC）， and low-density lipoprotein cholesterol （LDL-C） （P<0.05） and elevations in the level of high-density lipoprotein cholesterol （HDL-C） （P<0.05）. Moreover， the observation group outperformed the control group in recovering the levels of TG， LDL-C， and HDL-C （P<0.05， P<0.01）. In terms of TCM syndrome， hyperlipidemia was mostly caused by phlegm turbidity and obstruction. The total response rate in terms of TCM syndrome in the observation group was 87.30% （55/63）， which was higher than that （63.46%， 33/52） in the control group （χ²=9.102， P<0.01）. After treatment， the scores of total TCM symptoms， primary symptoms， and secondary symptoms decreased in both groups （P<0.05）， and the observation group had lower scores than the control group （P<0.01）. The observation group was superior to the control group in alleviating obesity， chest tightness， and low food intake （P<0.05）. In terms of safety， the level of aminotransferase was slightly elevated in the control group， and no obvious adverse reaction was observed in the observation group， with no statistical significance in the incidence of adverse reactions. ConclusionZhuyuwan combined with atorvastatin can not only recover blood lipid levels and alleviate TCM symptoms but also reduce the occurrence of adverse reactions.

Non-small cell lung cancer(NSCLC)is one of the most common and deadly malignant tumors worldwide,with surgical resection being the primary treatment for early-stage NSCLC.Tumor spread through air spaces(STAS)is a novel pattern of tumor dissemination into the air spaces in the lung.Its occurrence after sublobar resection is closely associated with recurrence and distant metastasis,making its con-sideration a vital factor in surgical strategy selection and prognostic evaluation.Patients with STAS-positive status exhibit significantly higher postoperative recurrence rates than do STAS-negative patients,with molecular mechanisms involving tumor microenvironment remodeling,specific genetic mutations,and epithelial-mesenchymal transition(EMT).Imaging techniques including computed tomography(CT)and positron emission tomography/CT have shown potential for preoperative STAS prediction,although their accuracy and practicality require improvement.This paper reviews the definition,pathological characteristics,and related mechanisms of STAS,with a focus on surgical ap-proach selection for STAS-positive patients and its role in cancer recurrence after sublobar resection of early-stage NSCLC.Future research directions include optimization of preoperative diagnostic methods for STAS,exploration of molecular targeted therapies,and development of imaging-based precision prediction models.

Acute hypobaric hypoxic brain damage is a potentially fatal high-altitude sickness. Autophagy plays a critical role in ischemic brain injury, but its role in hypobaric hypoxia (HH) remains unknown. Here we used an HH chamber to demonstrate that acute HH exposure impairs autophagic activity in both the early and late stages of the mouse brain, and is partially responsible for HH-induced oxidative stress, neuronal loss, and brain damage. The autophagic agonist rapamycin only promotes the initiation of autophagy. By proteome analysis, a screen showed that protein dynamin2 (DNM2) potentially regulates autophagic flux. Overexpression of DNM2 significantly increased the formation of autolysosomes, thus maintaining autophagic flux in combination with rapamycin. Furthermore, the enhancement of autophagic activity attenuated oxidative stress and neurological deficits after HH exposure. These results contribute to evidence supporting the conclusion that DNM2-mediated autophagic flux represents a new therapeutic target in HH-induced brain damage.

Objective Based on the process theory of stress effect,the structural equation model of the influencing factors of self-regulatory fatigue in maintenance hemodialysis patients is constructed,which provides theoretical bases and references for the formulation of intervention programs to relieve self-regulatory fatigue in patients.Method A total of 420 maintenance hemodialysis patients were surveyed using General Information Questionnaire,Self-Regulatory Fatigue Scale,Dialysis Symptom Index,Life Orientation Test-Revised,Perceived Social Support Scale,Brief Illness Perception Questionnaire and Medical Coping Styles Questionnaire.Results Total score of self-regulatory fatigue in maintenance hemodialysis patients was(49.52±10.93),and self-regulatory fatigue showed significant positive correlation with symptom distress,the illness perception,avoidance coping style,yieldly coping(r=0.476,0.428,0.303,0.611,all P＜0.01);self-regulatory fatigue showed significant negative correlation with perceived social support and dispositional optimism(r=-0.410,-0.652,all P＜0.01);it showed no significant correlation with facing coping(r=-0.032,P＞0.05).The Bootstrap analysis revealed that the mediation effect of yielding coping,dispositional optimism,perceived social support,and illness perception between symptom distress and self-regulatory fatigue was significant(95％CI:0.027～0.203).The overall effect of symptom distress on self-regulatory fatigue was(P＜0.001,95％CI:0.576～0.751);the direct effect was(P＜0.001,95％CI:0.170～0.357);the indirect effect was(P＜0.001,95％CI:0.332～0.485);the mediation effect accounted for 61.1％of the total effect value.Conclusion Maintenance hemodialysis patients have a high degree of self-regulatory fatigue,which needs to be further improved.Medical staff should timely identify and evaluate the symptom distress of patients,focus on guiding patients to adjust optimistic disease,provide patients with psychological guidance and stress coping strategies,reduce the negative coping behavior tendency,guide the patients correctly perceive support and care in social relations,help patients set up the correct disease cognition,thus reducing the patient's self-regulatory fatigue.

In order to mine candidate vaccine antigens against ticks and to control ticks safely and effectively,the aim of this study was to immunize rabbits with purified aquaporins(AQPs)rD-mAQP1,rDmAQP2 and rDmAQP3 of Dermacentor marginatus.Blood collections for Western blot and ELISA tests were performed.The anti-tick challenge was conducted.The optimal expression conditions of rDmAQP1,rDmAQP2 and rDmAQP3 were screened by SDS-PAGE gel electrophore-sis.The three recombinant proteins were purified by HisSepNi-NTA6FF purification column.Rab-bits were divided into four groups of three rabbits each,including a control group and three immu-nized groups.The three purified recombinant proteins were separately immunized to three groups of rabbits,and the rabbits were immunized once on the 0th,14th and 21st day.Blood samples were collected every 7 days to prepare polyclonal antibodies.The reactivity was detected by Western blot and the antibody titer was detected by ELISA.Tick challenge test was carried out after the anti-body titer increased.The results showed that the optimal expression conditions for rDmAQP1 were induced for 8 h at IPTG concentration of 1.0 mmol/L and 37 ℃;the optimal expression conditions for rDmAQP2 were induced for 7 h at IPTG concentration of 1.0 mmol/L and 37 ℃;and the opti-mal expression conditions for rDmAQP3 were induced for 5 h at IPTG concentration of 1.0 mmol/L and 37 ℃.Western blot results showed that rDmAQP1,rDmAQP2 and rDmAQP3 all had certain reactivity.The ELISA results showed that the antibody titers of rabbits immunized with rD-mAQP1,rDmAQP2 and rDmAQP3 were as follows:the total anti-tick effect of rDmAQP1 protein was 79.74％,and the inhibition rates on average full-blooded tick weight,average egg weight and average egg hatching rate were 9.43％,25.17％and 63.81％,respectively.The total anti-tick effect of rDmAQP2 protein was 78.78％,and the inhibition rates of average full-blooded tick weight,av-erage egg weight and average egg hatching rate of Dermacentor marginatus were 8.30％,20.14％and 68.26％,respectively.The total anti-tick effect of rDmAQP3 protein was 87.91％,and the inhi-bition rates of average full-blooded tick weight,average egg weight and average egg hatching rate were 3.23％,22.47％and 80.5％,respectively.Through serological test and anti-tick test,it has been found that rDmAQP1,rDmAQP2 and rDmAQP3 all have the potential of candidate antigens against ticks,among which rDmAQP3 has the best immune effect,which lays a foundation for the study of the function of rDmAQP1,rDmAQP2 and rDmAQP3.

Objective:To form the expert consensus on screening and evaluation of dysphagia with oral cancer patients (abbreviated as Consensus) , so as to standardize the relevant contents of screening and evaluation of dysphagia in the whole cycle of oral cancer. Methods:By referring to domestic and foreign literature related to dysphagia, combining with the specialty characteristics of oral cancer and the clinical experience of experts, a preliminary consensus was formed through in-depth interviews with experts. A total of 21 experts were selected for three rounds of expert letter consultation and expert meeting, the corresponding items were sorted out, analyzed and modified based on expert opinions, and the Consensus was finally formed. Results:The effective recovery rates of the three rounds of correspondence were 100.00% (21/21) , the expert authority coefficient was 0.91, the variation coefficient of each item was 0.04-0.20, and Kendall's harmony coefficient was 0.05 ( P<0.05) . The final consensus included four aspects, such as the effect of oral cancer on swallowing, the clinical manifestations of dysphagia, the basic procedures of screening and evaluation and the prevention and treatment of complications during evaluation. Conclusions:This Consensus is scientific and practical, which can provide clinical guidance for the screening and evaluation of dysphagia in the whole cycle of oral cancer.

Objective:To investigate the protective effect and mechanism of Acronychia pedunculata water extracts on UV-induced light damage of human keratinocytes.Methods:The experiment was conducted from December 2018 to April 2020 in the Guangxi Medical University Laboratory of Genetics. The photoaged keratinocyte model was used, the cells were co-cultured with different concentrations of Acronychia pedunculata water extracts. The cell proliferation rate was detected by CCK-8 method. The levels of reactive oxygen species (ROS), malondialdehyde (MDA), superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPX) and total antioxidant capacity (T-AOC) of cells were detected by a test kit. The levels of IL-1β, IL-6 and tumor necrosis factor-alpha (TNF-α) were determined by ELISA.Results:The proliferation of HaCaT cells was promoted by 0.5 mg/L-2.0 mg/L of the extracts. Compared with control group, the proliferation rate of HaCaT cells in the experimental group was significantly increased ( P<0.05). Compared with control group, the contents of ROS was decreased ( F=214.67, P<0.05), MDA was decreased ( F=811.88, P<0.05), SOD was increased ( F=28.95, P<0.05), CAT was increased ( F=213.31, P<0.05), GPX was increased ( F=65.10, P<0.05), T-AOC was increased ( F=305.58, P<0.05), IL-1β was decreased ( F=15.46, P<0.05), IL-6 was decreased ( F=59.2, P<0.05), and TNF-α was decreased ( F=33.13, P<0.05). Conclusions:The extracts of 0.5-2.0 mg/L of Acronychia pedunculata have protective effects on the photoaging cell model, which may be related to the increase of SOD, CAT, GPX and other antioxidant enzymes and the level of T-AOC in photoaging HaCaT cells, and the decrease of ROS, MDA content and the expression of inflammatory cytokines.
