ObjectiveTo explore the central neuroregulation mechanism of heat-sensitive moxibustion for knee osteoarthritis on pain relief. MethodsThirty patients who did not have experience of Deqi （得气） during heat-sensitive moxibustion treatment were assigned to the "non-Deqi group"， while another 30 patients who had experience of Deqi were assigned to the "Deqi group". Both groups received moxibustion at the left Heding （EX-LE2） acupoint. In the Deqi group， after the patients experienced sensation of Deqi at the acupoint， moxibustion was applied at approximately 3 cm from the skin for 10 minutes； in the non-Deqi group， moxibustion was also applied at approximately 3 cm from the skin for 10 minutes. Both groups received treatment once daily for 10 consecutive days. Knee joint pain was assessed before and after treatment using the visual analog scale （VAS）. Resting-state functional magnetic resonance imaging （rs-fMRI） scans were performed on all participants before the first treatment session and after the final session on the 10th day. The fractional amplitude of low-frequency fluctuations （fALFF） maps before and after treatment were processed using the SPM12 module by MATLAB. ResultsAfter treatment， VAS scores in both groups were significantly lower than before treatment （P＜0.05 or P＜0.01）， with the Deqi group showing significantly lower VAS scores than the non-Deqi group （P＜0.01）. Compared to before treatment， the Deqi group exhibited significant activation in the prefrontal cortex （t = 6.28）， white matter （t = 6.36）， and left temporal lobe （t = 9.33）， while significant inhibition was observed in the occipital lobe （t = -9.86） and right cerebrum （t = -4.54， P＜0.01）； in the non-Deqi group， significant changes after treatment were observed in the left occipital lobe （t = -6.42）， left medial frontal gyrus （t = -4.35）， left middle frontal gyrus （t = -4.74）， right superior frontal gyrus （t = -4.82）， right superior temporal gyrus （t = -6.61）， and right cerebellar posterior lobe （t = -8.64）， all of which were in inhibited states （P＜0.01）. Compared to the non-Deqi group， the Deqi group exhibited significant activation after treatment in the external nucleus （t = 5.77）， white matter （t = 3.58）， right cerebrum （t = 5.84）， left cerebellum （t = 5.35）， and left cerebrum （t = 4.32）， while significant inhibition was observed in the prefrontal cortex （t = -4.16）， occipital lobe （t = -4.87）， and precentral gyrus （t = -4.46， P＜0.01）. ConclusionsHeat-sensitive moxibustion provides better analgesic effects for knee osteoarthritis under state of Deqi. Its central neuroregulation mechanism may be related to the involvement of the frontal lobe， temporal lobe， occipital lobe， external nucleus， white matter， right cerebrum， left cerebellum， left cerebrum， and precentral gyrus in modulating pain signals.

The breakage pattern of unit particles during the production of oral solid dosage forms (OSD) is closely related to the quality of intermediate or final products. To accurately characterize the particles and study the evolution law of particle breakage, the Bonding model of the discrete element method (DEM) was used to investigate the breakage patterns of model parameters, particle shape and process conditions (loading mode and loading rate) on the dynamic breakage, force-time curve, breakage rate, maximum breakage size ratio and fracture strength of particles. The results showed that the particle breakage force was positively correlated with normal strength and bonded disk scale, negatively correlated with normal stiffness per unit area and tangential stiffness per unit area, and weakly correlated with tangential strength. The particle breakage rate was negatively correlated with the aspect ratio of the particles, and the maximum breakage size ratio was positively correlated with the aspect ratio of the particles; among the three loading modes, the breakage rate of compression breakage model was the largest, the breakage rate of shear breakage model was the second largest, and the breakage rate of wear breakage model was the smallest; the maximum breakage size ratio was positively correlated with the loading rate, the loading mode and the loading rate had no mutual influence on particle breakage rate, but had mutual influence on the maximum breakage size ratio. The research results will provide a theoretical basis for the shift of OSD from batch manufacturing to advanced manufacturing.

Transient receptor potential vanilloid-1(TRPV1) channel is a non-selective ligand-gated cationic channel with multiple activation mechanisms in the transient receptor potential subfamily. In recent years, a large number of studies have found that TRPV1 plays an important role in the field of cardiovascular diseases such as hypertension and atherosclerosis. With the in-depth study of traditional Chinese medicine, it has been found that Chinese medicine monomers and their active components can activate or inhibit TRPV1 channels, which has certain potential in the study of cardiovascular diseases. In this paper, the role of TRPV1 channel in cardiovascular diseases and the research progress of traditional Chinese medicine prevention and treatment of cardiovascular diseases based on TRPV1 channel are reviewed, in order to provide new ideas for prevention and treatment of cardiovascular system diseases.

Objective To explore the trend in self-management efficacy and exercise compliance among patients within 6 months after radical resection of lung cancer and analyse the predictive correlation between the factors to provide references for improvement of exercise compliance in patients after lung cancer surgery.Methods Convenience sampling was used to select patients who had surgery of radical resection of lung cancer for the first time in the departments of thoracic surgery of two Grade IIIA hospitals in Nanchong between December 2022 and May 2023.The Chinese-version strategies used by people to promote health(C-SUPPH)and exercise compliance scale were employed to assess the self-management efficacy and patient exercise compliance at four time points:1 day before discharge(T1)and 1 month(T2),3 months(T3)and 6 months(T4)after surgery.A cross-lagged model was constructed to analyse the causal correlation between self-management efficacy and exercise compliance.Results Within 6 months after surgery,both of self-management efficacy and exercise compliance in the patients after radical resection of lung cancer were seen initially increased and then decreased(P<0.05).The cross-lagged model revealed that self-management efficacy and exercise compliance during the early postoperative period(TI-T2)exhibited reciprocal causation(β=0.254,P=0.003;β=0.332,P=0.007).Between T2 and T3,higher self-management efficacy positively predicted an increased exercise compliance(β=0.286,P<0.001).However,during T3 and T4,no predictive relationship was observed between the indicators(P>0.05).Conclusion The self management efficacy of patients after lung cancer sugery is at middle level and their exercise compliance is at low level.This study indicates that the initial levels of self-management efficacy and exercise compliance among patients after radical resection of lung cancer do not necessarily reflect a long-term trend.The predictive correlation between the two factors also varies over the time.Healthcare providers should consider the dynamic changes and individual differences across different stages after surgery,and implement timely and targeted intervention.

Enteropathogenic Escherichia coli(EPEC),a zoonotic foodborne pathogen,can induce severe and prolonged di-arrhea,thus substantially affecting global public health safety.To understand the pathogenicity of EPEC and its potential risk to human health,this study investigated the antimicrobial resistance and genome-wide characteristics of EPEC originating from ducks.After identification of EPEC with the plate method and PCR,antimicrobial susceptibility of the isolates was examined with the microbroth dilution method.In addition,analyses of serotype,sequence type(ST),and plasmid incompatibility groups were conducted with whole-genome sequencing(WGS)and bioinformatic methods.Ten EPEC isolates were identified,including serotypes O71∶H40 and O3∶H21.All EPEC strains exhibited multiple drug resistance.The highest proportion of resistance(100％)was observed to ciprofloxacin,streptomycin,tetracycline,and polymyxin B.In contrast,the isolates showed susceptibility to cefoxitin,amikacin,and imipenem.Furthermore,all strains carried the tetracycline resistance gene tet(A)and extended-spectrum β-lactamase(ESBL)resistance genes,including blaOXA-10,blaTEM-1A,and blaTEM-1B.Various virulence genes,associated primarily with the secretory system,were de-tected in the isolates.However,no bf p genes or per ARC genes were identified,thus indicating that the EPEC isolates were atypical EPEC(aEPEC).The results demonstrated the presence of multiple antimicrobial resistance,multiple resistance and viru-lence genes,and various plasmid incompatibility groups,thus in-dicating potential pathogenicity to humans.Strengthened monitoring of duck-derived EPEC is crucial to effectively control the spread of the pathogen and safeguard public health.

Objective To explore the longitudinal trajectories of symptom clusters in patients with rectal cancer within 6 months after laparoscopic anal preservation surgery,and analyze the predictive factors of each trajectory subgroup.Methods A longitudinal survey was conducted to select 128 patients who underwent laparoscopic anal preservation surgery for rectal cancer at the Department of Gastrointestinal Surgery,a tertiary hospital in Nanchong from November 2021 to April 2022.The general information questionnaire,Chinese version of Anderson Symptom Inventory for Gastrointestinal Cancer and Charlson Comorbidity Index were used to conduct follow-up surveys of the selected patients at 2 weeks,1 month,3 months and 6 months after surgeiy.The symptom cluster were extracted by exploratory factor analysis,and the latent category growth model was constructed to identify the trajectory subgroups of each symptom cluster.The predictive factors of each trajectory subgroup were analyzed by Mplus statistical software.Results There were 4 symptom clusters within 6 months after laparoscopic anus preserving surgeiy for rectal cancer,which were named as sickness symptom cluster,psychological-sleep symptom cluster,gastrointestinal symptom cluster,and psychological-treatment-related symptom cluster.The variance contribution rates were 65.173％,66.225％,62.421％,and 60.492％,respectively.The latent class growth model identified that there are 4 to 5 trajectory subgroups in the symptom cluster.Gender,education level,Charles Comorbidity Index,clinical T stage,medical cost burden,and treatment method were the predictors of high-risk trajectory subgroups in the symptom cluster(P＜0.05).Conclusion There are 4 symptom clusters within 6 months after laparoscopic anus preserving surgeiy for rectal cancer.The gastrointestinal symptom cluster is a specific symptom cluster for this type of patients with the heaviest symptom burden.The overall trajectory of each symptom cluster shows a dynamic decline trend,but individual trajectoiy subgroups still have an exacerbation trend.There are differences in predictive factors for different symptom clusters.Clinical medical staff should pay attention to the management of symptom clusters in patients with female patients,low education level,high Charles Comorbidity Index,high clinical T stage,heavy medical cost burden,and patients whose treatment method is chemotherapy plus surgery.High-risk groups should be timely identified;corresponding intervention methods were dynamically adjusted;the quality of precision nursing was improved.

Heat stroke(HS)is a serious life-threatening disease caused by heat injury and characterized by a core body temperature>40℃with central nervous system dysfunction and multi-organ failure.The main pathophysiological manifestations of HS are the thermal acute phase response and thermoregulatory imbalance.Proteins are particularly sensitive to heat,and the thermal environment can cause massive protein denaturation,resulting in the deposition of unfolded and misfolded proteins in the cytoplasm,causing cellular dysfunction and even death.The unfolded protein response(UPR),mainly divided into the endoplasmic reticulum UPR and the mitochondrial UPR,is an important physiological process that helps proteins to fold correctly or degrade irretrievably denatured proteins.This paper summarizes the regulatory mechanisms of UPR,the relationship between UPR and severe diseases,as well as the relationship between HS and UPR to provide new ideas for the treatment of HS.

Aim To explore the possibility of resveratrol ( RES) combined with irinotecan ( IRI) in the treatment of colorectal cancer ( CRC ) and the underlying molecular mechanism of RES ameliorating IRI chemoresistance of CRC cells. Methods CRC cells used in this study were HT-29 and RKO cells. The effects of RES, IRI and their combination on the proliferation of CRC cells were analyzed by MTT assay and colony formation assay. The effects of RES,IRI and their combination on the migration of CRC cells were assessed by Wound-healing assay. On this basis,the role of RES in regulating IRI chemoresistance of CRC cells and the underlying molecular mechanisms were further explored. Results The proliferation and migration ability of CRC cells in the RES and IRI combined treatment group were significantly lower than those in the IRI treated group, which showed that RES could enhance the inhibiting effect of IRI on the proliferation and migration of CRC cells, indicating that RES was able to a-meliorate the chemoresistance of CRC cells to IRI. And remarkably lower marker proteins expression levels of EGFR/AKT/mTOR signaling pathway in the RES and IRI combined treatment group was observed. Moreover, both EGFR activator (NSC 228155) and AKT activator (SC79) could reverse the ameliorating effect of RES on IRI chemoresistance of CRC cells, whereas AKT inhibitor (MK2206 ) could partially reverse the effect of NSC 228155. Conclusions RES can inhibit the proliferation and migration of CRC cells by down-regulating EGFR/AKT/mTOR signaling pathway, so as to ameliorate the chemoresistance of CRC cells to IRI, suggesting that RES combined with IRI can be a promising novel treatment for CRC.

Hypertension is a risk factor for a variety of cardiovascular diseases, which is an important public health problem in the world today. MiRNAs are a class of highly conserved non-coding small RNAs. In recent years, studies have found that miRNAs are involved in the occurrence and development of hypertension through a variety of ways, causing damage to the important target organs of hypertension, such as heart, brain and kidney. This article reviews the research progress of miRNA in hypertension in recent years, in order to clarify its role in the process of hypertension and target organ damage, and provide ideas for exploring new therapeutic targets of hypertension.
