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.

Objective To investigatethe relationship between gastroesophageal reflux disease (GERD) symptoms and clinicopathological characteristics, p53 expression, and survival of Chinese patients with esophageal adenocarcinoma. Methods A total of 3882 patients with esophageal adenocarcinoma, 970 matched patients with esophageal squamous cell carcinoma, and 970 matched patients with gastric cardia adenocarcinoma were included to compare the incidence of GERD symptoms. Patients with esophageal adenocarcinoma were divided into two groups according to the presence and absence of GERD symptoms. The differences in clinicopathological characteristics and p53 expression between the two groups were compared by chi-square test, and the differences in survival between the two groups were compared by landmark analysis. Results The incidence of GERD symptoms increased successively in esophageal squamous cell carcinoma, esophageal adenocarcinoma, and gastric cardia adenocarcinoma. In patients with esophageal adenocarcinoma, the proportions of male, less than 65 years old, lower thoracic tumors, tumors without squamous cell carcinoma, poorly differentiation, early tumors (stage 0-I), and p53-positive tumors in the group with GERD symptoms were higher than those in the group without GERD symptoms; moreover, the long-term survival (≥15 years) was better. Conclusion GERD symptom is an important clinical sign of esophageal adenocarcinoma. It is closely related to specific clinicopathological characteristics, p53 overexpression, and good long-term prognosis.

Post-orgasmic illness syndrome (POIS) is a rare condition characterized by the rapid onset of extreme fatigue, flu-like symptoms, difficulty concentrating, depression, nasal congestion, rhinorrhea, itchy eyes, and other physical and psychological discomforts following ejaculation. This report presents the outcomes of two patients with POIS who underwent a two-year course of autologous seminal plasma subcutaneous cluster immunotherapy. Treatment efficacy was assessed using methods such as the symptom Visual Analogue Scale (VAS), the Union Physio-Psycho-Social Assessment Questionnaire (UPPSAQ)-70, and the Short Form 36 Health Survey (SF-36). The results suggest that autologous seminal plasma subcutaneous cluster immunother-apy may be a safe and effective therapeutic approach for POIS.

The aryl hydrocarbon receptor (AhR) plays a crucial role in regulating many physiological processes. Activating the AhR-CYP1A1 axis has emerged as a novel therapeutic strategy against various inflammatory diseases. Here, a practical in situ cell-based fluorometric assay was constructed to screen AhR-CYP1A1 axis modulators, via functional sensing of CYP1A1 activities in live cells. Firstly, a cell-permeable, isoform-specific enzyme-activable fluorogenic substrate for CYP1A1 was rationally constructed for in-situ visualizing the dynamic changes of CYP1A1 function in living systems, which was subsequently used for discovering the efficacious modulators of the AhR-CYP1A1 axis. Following screening of a compound library, LAC-7 was identified as an efficacious activator of the AhR-CYP1A1 axis, which dose-dependently up-regulated the expression levels of both CYP1A1 and AhR in multiple cell lines. LAC-7 also suppressed macrophage M1 polarization and reduced the levels of inflammatory factors in LPS-induced bone marrow-derived macrophages. Animal tests showed that LAC-7 could significantly mitigate DSS-induced ulcerative colitis and LPS-induced acute lung injury in mice, and markedly reduced the levels of multiple inflammatory factors. Collectively, an optimized fluorometric cell-based assay was devised for in situ functional imaging of CYP1A1 activities in living systems, which strongly facilitated the discovery of efficacious modulators of the AhR-CYP1A1 axis as novel anti-inflammatory agents.

Objective To explore the diagnostic value of musculoskeletal ultrasound in patients with limb pain.Methods A total of 80 patients with limb pain admitted to the First Hospital of Nanchang from January 2021 to December 2022 were included in the study.All patients received magnetic resonance imaging(MRI)and musculoskeletal ultrasound on admission.The consistency and coincidence rate of musculoskeletal ultrasound and MRI in diagnosing the cause of limb pain were compared.Results In the 80 patients,MRI and musculoskeletal ultrasound detected positive results in 78 cases,accounting for 97.50%,and 2 cases had no clear disease type.According to the results of MRI,there were 75 cases in which musculoskeletal ultrasound diagnosis of the cause of limb pain was consistent with the MRI results,and total coincidence rate was 96.15%(75/78),with excellent consistency(Kappa=0.907).Conclusion Musculoskeletal ultrasound can clearly display the fine tissue structure,and the diagnosis accuracy of limb pain is high,and the diagnosis consistency with MRI is excellent.

Objective In this study,we aimed to use network pharmacology techniques to predict the key targets of a prescription of Ziziphi spinosae semen formula(ZSSF)compound for depression,and to verify its mechanism of action using a zebrafish model of rifampicin-induced depression.Methods The drug targets of ZSSF were retrieved from the TCMSP database,and the target names were corrected using the UniProt database.Depression-related targets were identified using the GeneCards,OMIM,and NCBI databases.Protein-protein interaction information for the shared targets was predicted using the STRING database.The collected data were then analyzed using the Metascape database to determine GO and KEGG pathway enrichment,and the result were visualized using microbiotics.Behavioral experiments and reverse-transcription quantitative PCR experiments were conducted to verify the therapeutic effects of ZSSF on a zebrafish depression model induced by risperdal.Results 188 targets were screened to find the interactions between depression and ZSSF.The protein-protein interaction result showed that ZSSF primarily targeted TNF-α,IL-2,IL-6,IL-1β,and IL-10 to produce its antidepressant effect.KEGG pathway enrichment analysis revealed that ZSSF exerted its effects on depression through various signaling pathways,including the TNF,PI3K-Akt,and cGMP-PKG signaling pathways.The result of the animal experiments showed that the treatment groups given high,medium,and low doses of ZSSF exhibited significant improvements in movement distance under acoustic and light stimulation compared with the model group(P＜0.05).The speed of movement of the treatment groups was also significantly faster(P＜0.01).Additionally,the mRNA expression levels of TNF-α,IL-2,IL-6,IL-1β,and IL-10 were up-regulated in the brain tissues of zebrafish in the high-,medium-,and low-dosage groups of ZSSF compared those in the model group(P＜0.001).Conclusions ZSSF exerts its antidepressant effect through multiple components and targets,and its antidepressant effects may be associated with its inhibition of inflammatory factors.
