OBJECTIVE: To preliminarily investigate the effect of buccal acupuncture therapy on ameliorating postoperative pain and enhancing recovery quality among patients undergoing radical resection of gastrointestinal cancers. METHODS: Fifty-two participants were randomized at a 1:1 ratio to either the buccal acupuncture or the control group. The acupuncture protocol entailed targeting 5 predetermined acupoints [CA-2 (Upper jiao), CA-3 (Middle jiao), CA-4 (Lower jiao), CA-6 (back), and CA-7 (waist) and two adjustable acupoints [CA-1 (head) and CA-8 (sacrum)] on each side of the face. The outcomes included the Numeric Rating Scale (NRS) scores for each day within 7 days postoperatively, 15-Item Quality of Recovery Scale (QoR-15) scores, analgesics consumption during and after surgery, incidences of postoperative nausea and vomiting, and perioperative levels of interleukin-6 and glucose. Adverse events related to acupuncture were recorded. RESULTS: Of the initial 52 participants, 46 completed the study and were included in the analysis. Findings indicated that the buccal acupuncture group experienced significantly reduced resting NRS scores in post-anesthesia care unit and throughout the postoperative phase (P=0.001 and P=0.003, respectively), along with enhanced QoR-15 scores on the 3rd postoperative day (P=0.008), compared to the control group. No notable differences were identified in the remaining indicators (P>0.05). CONCLUSION Buccal acupuncture therapy demonstrated significant effectiveness in reducing postoperative pain and improving recovery quality for patients undergoing radical resection of gastrointestinal cancers, presenting a viable intervention without associated adverse outcomes.

Objective To assess the status of rodent infestation in commercial kitchens using data from the‘Bright Kitchen, Clean Stove' initiative. The potential use of artificial-intelligence(AI)-based surveillance systems to monitor rodent density was explored, thereby providing a scientific basis for rodent control strategies. Methods As a component of the ‘Bright Kitchen, Clean Stove' initiative, the Minhang District Market Supervision Administration in Shanghai has installed cameras in 297 kitchens. These systems incorporate an AIpowered rodent image recognition method that automatically captures and stores the first image captured in each kitchen each day when a rodent is detected. In 2023, the system collected and stored 736 screenshots of rodents. Following manual verification,720 of the images were confirmed to contain rodents. The images were analyzed by noting the time, location, and kitchen area, and the species were manually identified to assess the population density. Results Rodent activity was detected in 34 of the 297 monitored kitchens, with an overall infestation rate of 11.45%. Of the 720 confirmed images of rodents, Rattus norvegicus(brown rat)was the predominant species, present in 409(56.81 %)images. Rodents were primarily concentrated in hot food preparation spaces. The density fluctuation curve had a multimodal pattern peaking in spring and autumn. The peak of daily activity was between 22: 00 and 2: 00. There was a significant difference in the rodent detection frequency between weekends and weekdays during peak hours and during non-peak hours(χ2=7.18, P＜ 0.01). Conclusions The ‘Bright Kitchen, Clear Stove' smart monitoring system has been proven to be applicable to rodent density monitoring. To control rodents in commercial kitchens, greater efforts are required to address and identify the specific infesting conditions and the key points in the control process.

Objective To quantitatively analyze and evaluate the content of rehabilitation policy for people with disabilities in China. Methods This study focused on ten national policies of disability rehabilitation issued from 2021 to 2023.It employed text mining techniques to process policy texts and constructed a policy modeling consistency index model for dis-ability rehabilitation policies in China.The relevant policies were evaluated and analyzed quantitatively. Results The disability rehabilitation policies in China were relatively comprehensive in terms of policy transparency,op-erational mechanisms and policy nature.However,there was still a need for optimization in terms of policy per-spectives,target groups,incentive mechanisms,and other aspects. Conclusion The overall quality of disability rehabilitation policy texts at the national level in China is relatively good.There is a need to further enhance the predictability of policy objectives,clarify the responsibilities and division of labor among various departments,and improve policy incentive mechanisms in future policy formulation,which will further refine China's disability rehabilitation policy system and contribute to high-quality develop-ment of the disability cause.

Gastrointestinal dyskinesia is a central factor contributing to the development of functional dyspepsia(FD),which is characterized by the rupture of the gastrointestinal nerve-Cajal interstitial cell-smooth muscle network.Gan Yu Pi Xu are similar to endoplasmic reticulum stress(ERs)-mitochondrial autophagy homeostasis imbalance.Mitochondrial autophagy disorders are the biological basis of Pi Xu,and Gan Yu is the macroscopic manifestation of ERs,and regulation of ERs-mitochondrial autophagy pathway is an important way to prevent and control FD.In this paper,we start from the theory of"liver-spleen correlation",combine the changes of endoplasmic reticulum and mitochondria in the process of gastrointestinal dyskinesia,reveal the correlation between the pathogenesis of Gan Yu Pi Xu and the autophagy of ERs and mitochondria,and elucidate the mechanism of gastrointestinal dyskinesia by the method of Shu Gan Jian Pi,so as to provide a new point of view for the treatment of gastrointestinal dyskinesia in FD.

Purpose::The toughest challenge in pedestrian traffic accident identification lies in ascertaining injury manners. This study aimed to systematically simulate and parameterize 3 types of craniocerebral injury including impact injury, fall injury, and run-over injury, to compare the injury response outcomes of different injury manners.Methods::Based on the total human model for safety (THUMS) and its enhanced human model THUMS-hollow structures, a total of 84 simulations with 3 injury manners, different loading directions, and loading velocities were conducted. Von Mises stress, intracranial pressure, maximum principal strain, cumulative strain damage measure, shear stress, and cranial strain were employed to analyze the injury response of all areas of the brain. To examine the association between injury conditions and injury consequences, correlation analysis, principal component analysis, linear regression, and stepwise linear regression were utilized.Results::There is a significant correlation observed between each criterion of skull and brain injury ( p < 0.01 in all Pearson correlation analysis results). A 2-phase increase of cranio-cerebral stress and strain as impact speed increases. In high-speed impact (> 40 km/h), the Von Mises stress on the skull was with a high possibility exceed the threshold for skull fracture (100 MPa). When falling and making temporal and occipital contact with the ground, the opposite side of the impacted area experiences higher frequency stress concentration than contact at other conditions. Run-over injuries tend to have a more comprehensive craniocerebral injury, with greater overall deformation due to more adequate kinetic energy conduction. The mean value of maximum principal strain of brain and Von Mises stress of cranium at run-over condition are 1.39 and 403.8 MPa, while they were 1.31, 94.11 MPa and 0.64, 120.5 MPa for the impact and fall conditions, respectively. The impact velocity also plays a significant role in craniocerebral injury in impact and fall loading conditions (the p of all F-test < 0.05). A regression equation of the craniocerebral injury manners in pedestrian accidents was established. Conclusion::The study distinguished the craniocerebral injuries caused in different manners, elucidated the biomechanical mechanisms of craniocerebral injury, and provided a biomechanical foundation for the identification of craniocerebral injury in legal contexts.

Objective The aim of this study was to investigate the molecular regulatory mechanism of cancer susceptibility candidate 15(CASC15),a long-stranded non-coding RNA(lncRNA),in hepatocellular carcinoma(HCC).Methods Bioinformat-ics methods were used to predict the expression of target genes and analyze the relationship between the expression of target genes and the survival time of patients;Hepatocellular carcinoma tissues and adjacent tissues from patients with HCC were collected;CCK-8,Tr-answell,and flow cytometry experiments were used to detect proliferation,invasion,migration and apoptosis of SMMC7721 cells and Huh-7 cells;The dual-luciferase assay was used to detect the targeting relationship between miR-144-3p and CASC15,as well as leucine rich repeat containing protein 1(LRRC1);RT-qPCR and Western blot were used to detect mRNA and protein expression of target genes;Immunofluorescence was used for protein localization of target genes;Replicate experiment was performed to verify the effect of CASC15/miR-144-3p/LRRC1 on the progression of HCC.In vivo experiment was performed to verify the effect of CASC15 on HCC progression.Results TCGA database and RT-qPCR assay showed high expression of CASC15,low expression of miR-144-3p,and high expression of LRRC1 in HCC tissues and cells(P<0.05).The results of cell function experiments on proliferation,inva-sion and migration showed that CASC15 and LRRC1 played a promoting role in tumor development,while miR-144-3p had an inhibi-tory effect,consistent with the results of apoptosis experiments(P<0.05).Cell function experiments showed that CASC15 inhibited miR-144-3p function,miR-144-3p inhibited LRRC1,and CASC15 bound to miR-144-3p,leading to the upregulation of LRRC1.The replicate experimental results indicated that CASC15 promoted LRRC1 expression through inhibiting miR-144-3p,thereby pro-moting HCC cell proliferation,invasion and migration,and inhibiting apoptosis.Conclusion CASC15 may promote HCC progression by regulating the miR-144-3p/LRRC1 axis.
