Purpose: The aim of this study was to investigate the feasibility of an intelligent handheld ultrasound (US) device for assisting non-expert general practitioners (GPs) in detecting carotid plaques (CPs) in community populations. Methods: This prospective parallel controlled trial recruited 111 consecutive community residents. All of them underwent examinations by non-expert GPs and specialist doctors using handheld US devices (setting A, setting B, and setting C). The results of setting C with specialist doctors were considered the gold standard. Carotid intima-media thickness (CIMT) and the features of CPs were measured and recorded. The diagnostic performance of GPs in distinguishing CPs was evaluated using a receiver operating characteristic curve. Inter-observer agreement was compared using the intragroup correlation coefficient (ICC). Questionnaires were completed to evaluate clinical benefits. Results: Among the 111 community residents, 80, 96, and 112 CPs were detected in settings A, B, and C, respectively. Setting B exhibited better diagnostic performance than setting A for detecting CPs (area under the curve, 0.856 vs. 0.749; P<0.01). Setting B had better consistency with setting C than setting A in CIMT measurement and the assessment of CPs (ICC, 0.731 to 0.923). Moreover, measurements in setting B required less time than the other two settings (44.59 seconds vs. 108.87 seconds vs. 126.13 seconds, both P<0.01). Conclusion Using an intelligent handheld US device, GPs can perform CP screening and achieve a diagnostic capability comparable to that of specialist doctors.

AIM To prepare the oral lyophilized tablets of gastrodin-coated micropowder.METHODS Fluidized bed bottom spray method was adopted in the preparation of coated micropowder,after which the oral lyophilized tablets were further prepared.With mannitol consumption,pullulan consumption and xanthan gum consumption as influencing factors,comprehensive score for appearance traits,moisture,disintegration time and the sedimentation volume ratio as an evaluation index,the formulation was optimized by Box-Behnken method,then the taste-masking effect,appearance traits,moisture,disintegration time,content uniformity and dissolution rate were investigated.RESULTS The optimal formulation was determined to be 44.20 mg/tablet for mannitol consumption,3.70 mg/tablet for pullulan consumption,1.30 mg/tablet for xanthan gum consumption,66.67 mg/tablet for coated micropowder,and 1.5 mg/tablet for sucralose micropowder,the comprehensive score was 17.43.The obtained oral lyophilized tablets demonstrated good taste-masking effect,appearance traits and content uniformity with the disintegration time of 3-5 s,whose dissolution rates were less than 5％within 3 min in the simulated oral environment(phosphate buffer solution at pH 6.8)and more than 85％within 15 min in the simulated gastric environment(hydrochloric acid solution at pH 1.2).CONCLUSION The oral lyophilized tablets of gastrodin-coated micropowder display good taste,ease of swallowing and simple and feasible preparation process,which can provide a new idea for the taste improvement of other oral lyophilized tablets and unpleasant-smelling raw medicines.

BACKGROUND:Patients with chronic ankle instability tend to overpronate when walking,which increases the risk of ankle sprain during the stance phase of the walking cycle.Clinicians often use Kinesio taping or athletic taping for ankle taping.Since Kinesio taping is elastic and athletic taping cannot be stretched,there are differences in technical applications and physiological mechanisms between them,which may result in different rehabilitation effects.OBJECTIVE:To compare the effects of Kinesio taping and athletic taping on the frontal plane of the foot motion and the horizontal plane of the tibia motion in patients with chronic ankle instability during the stance phase of walking.METHODS:Forty patients with chronic ankle instability were randomly divided into Kinesio taping group and athletic taping group.In the Kinesio taping group,two patches were pasted from the inside to the outside of the hind foot to generate pulling tension that facilitates foot eversion;in the athletic taping group,ankle locking basket taping was used.Walking tests were conducted on an electric treadmill before and after taping.A three-dimensional motion analysis system was used to obtain the kinematic parameters of the subjects'foot and tibia.RESULTS AND CONCLUSION:After taping,in the Kinesio taping group,the foot valgus angle increased in the early stance phase(P<0.05),but there was no effect on foot position in the late stance phase(P>0.05).After taping,in the athletic taping group,internal rotation of the tibia increased in the late stance phase(P<0.05);however,there was no significant change in tibial position in the early stance phase(P>0.05).To conclude,compared with athletic taping,Kinesio taping can provide a flexible pulling force that is beneficial for foot eversion in the early stance phase of the gait cycle,while not restricting normal foot inversion in the late stance phase.Therefore,Kinesio taping may be a practical rehabilitation therapy for patients with chronic ankle instability,correcting abnormal motion of the ankle joint without restricting its natural motion.

OBJECTIVE: To explore clinical efficacy of bone cement filling combined with lower extremity arterial balloon dilation in treating Wagner grade Ⅳ diabetic foot (DF). METHODS: From January to October 2024, 9 Wagner grade Ⅳ DF patients with lower extremity vascular occlusion were admitted, including 7 males and 2 females, aged from 51 to 87 years old;5 patients on the left side and 4 patients on the right side. All patients were underwent stageⅠdebridement of the affected foot and bone cement filling, and treated with lower extremity arterial balloon dilation after operation, they were. After the formation of the induced membrane, stageⅡwound repair was performed. The wound healing time and condition were observed. Ankle-brachial index (ABI) was used to evaluate the lower extremity vascular perfusion before operation and 3 months after operation, respectively. RESULTS: The wounds of all 9 patients healed completely, and the healing time ranged from 45 to 65 days. All patients were followed up for at least 6 months without recurrence. The skin of the affected foot wound healed with keratinization, and there was mild scar hyperplasia locally (1 patient had necrosis of the adjacent toe after stageⅠsurgery and was debridement and toe amputation again). The narrowed or occluded blood vessels of the lower extremities were all recanalized. ABI recovered from 0.3 to 0.5 before operation to 1.0 to 1.1 at 3 months after operation. CONCLUSION Bone cement filling combined with lower extremity arterial balloon dilation for the treatment of grade Wagner Ⅳ DF is conducive to promoting healing of the affected foot, effectively preventing secondary ulceration of the affected foot, and clinical therapeutic effect is satisfactory.

Two novel diketopiperazines (1 and 5), along with ten known compounds (2-4, 6-12) demonstrating significant skin inflammation inhibition, were isolated from a marine-derived fungus identified as Aspergillus sp. FAZW0001. The structural elucidation and configurational reassessments of compounds 1-5 were established through comprehensive spectral analyses, with their absolute configurations determined via single crystal X-ray diffraction using Cu Kα radiation, Marfey's method, and comparison between experimental and calculated electronic circular dichroism (ECD) spectra. Compounds 1, 2, and 8 exhibited significant anti-inflammatory activities in Propionibacterium acnes (P. acnes)-induced human monocyte cell lines. Compound 8 demonstrated the ability to down-regulate interleukin-1β (IL-1β) expression by inhibiting Toll-like receptor 2 (TLR2) expression and modulating the activation of myeloid differentiation factor 88 (MyD88), mitogen-activated protein kinase (MAPK), and nuclear factor κB (NF-κB) signaling pathways, thus reducing the cellular inflammatory response induced by P. acnes. Additionally, compound 8 showed the capacity to suppress mitochondrial reactive oxygen species (ROS) production and nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3) inflammasome activation, thereby reducing IL-1β maturation and secretion. A three-dimensional quantitative structure-activity relationships (3D-QSAR) model was applied to compounds 5-12 to analyze their anti-inflammatory structure-activity relationships.

OBJECTIVE: Pneumoconiosis, a lung disease caused by irreversible fibrosis, represents a significant public health burden. This study investigates the causal relationships between gut microbiota, gene methylation, gene expression, protein levels, and pneumoconiosis using a multi-omics approach and Mendelian randomization (MR). METHODS: We analyzed gut microbiota data from MiBioGen and Esteban et al. to assess their potential causal effects on pneumoconiosis subtypes (asbestosis, silicosis, and inorganic pneumoconiosis) using conventional and summary-data-based MR (SMR). Gene methylation and expression data from Genotype-Tissue Expression and eQTLGen, along with protein level data from deCODE and UK Biobank Pharma Proteomics Project, were examined in relation to pneumoconiosis data from FinnGen. To validate our findings, we assessed self-measured gut flora from a pneumoconiosis cohort and performed fine mapping, drug prediction, molecular docking, and Phenome-Wide Association Studies to explore relevant phenotypes of key genes. RESULTS: Three core gut microorganisms were identified: Romboutsia ( OR = 0.249) as a protective factor against silicosis, Pasteurellaceae ( OR = 3.207) and Haemophilus parainfluenzae ( OR = 2.343) as risk factors for inorganic pneumoconiosis. Additionally, mapping and quantitative trait loci analyses revealed that the genes VIM, STX8, and MIF were significantly associated with pneumoconiosis risk. CONCLUSIONS This multi-omics study highlights the associations between gut microbiota and key genes ( VIM, STX8, MIF) with pneumoconiosis, offering insights into potential therapeutic targets and personalized treatment strategies.
