Objective To investigate the anatomical structure and surface location of the Lieque(LU7)acupoint.Methods Firstly,the anatomical localization descriptions of the Lieque(LU7)acupoint from classical medical literature were reviewed and summarized.A total of 21 participants were recruited from Shandong Provincial Hospital Affiliated to Shandong First Medical University from January to March 2025.A Cartesian coordinate system was established over the Lieque(LU7)region on the right forearm.Following standardized manual pressure stimulation,the coordinates of the participant′s reported acupoint sensations were recorded.Based on surface pressure mapping result,10 participants were arbitrarily selected for acupuncture intervention.Upon elicitation of acupoint sensation,the ultrasound imaging was used for real-time visualization of anatomical spatial relationships between the needle tip and distal radial osseous landmarks.Five red latex-perfused adult upper limb specimens were selected for microdissection of the Lieque(LU7)regions pre-localized via ultrasonography,achieving definitive structural characterization of its anatomical strata.Another 10 participants were arbitrarily selected to find the physical structure of the Lieque(LU7)acupoint using ultrasound,and the similarities and differences of acupoint sensation responses were verified using acupuncture needle insertions into both the demarcated zone and peripheral tissues.Results The descriptions of the localization of the Lieque(LU7)acupoint in ancient books can be summarized as"one and a half cun above the wrist side"longitudinally,and"at the intersection head,between two tendons and two bones in the hollow"transversely.During surface pressure application,the sites of the participant′s elicited acupoint sensation were anatomically concentrated in the proximal depression adjacent to the radiopalmar ridge,specifically at the transitional interface between the extensor pollicis brevis tendon and scaphoid bone.During acupuncture-induced acupoint sensation,ultrasound imaging demonstrated that the location of the needle tip was located within the proximal depression adjacent to the radiopalmar ridge,accompanied by arterial hemodynamic perfusion signals into adjacent osseous interfaces.Microdissection findings revealed perforating branches of the radial artery traversing the cortical bone interface within the Lieque(LU7)acupoint region.Acupuncture stimulation at the proximal depression adjacent to the radiopalmar ridge elicited consistent acupoint sensations in all 10 participants,and the acupoint sensations differed from those of other surrounding tissues.Conclusion The anatomical structure of Lieque(LU7)acupoint is located within the proximal depression adjacent to the radiopalmar ridge,characterized by the presence of"hilus of bone"structure.

Objective:To evaluate the safety and effectiveness of physician modified stent grafts technique and in situ fenestration technique for reconstructing the left subclavian artery in endovascular repair of thoracic aortic lesions with insufficient proximal landing area.Methods:A retrospective analysis was conducted on the clinical data of 75 patients with aortic arch lesions treated with physician modified stent grafts and in situ fenestration techniques at the Interventional Diagnosis and Treatment Department of Beijing Anzhen Hospital affiliated with Capital Medical University from November 2021 to March 2024. Among them, 52 patients received within physician modified stent grafts (PMSGs group) and 23 patients received in situ fenestration (ISF group). Based on two fenestration techniques, to analyze the technical success rate of endovascular repair in reconstructing the left subclavian artery in the perioperative and early following up adverse events both groups.Results:The success rate of PMSGs group technique was 92.31% (48/52), while the success rate of ISF technique was 91.30%(21/23). In the PMSGs group, there was 1 case of TypeⅠa endoleak and 3 cases of TypeⅠc endoleak immediately during endovascular repair; There was 1 case of TypeⅠa endoleak and 1 case of vascular injury in the ISF group immediately during endovascular repair. One case of perioperative cerebral infarction and one case of transient blindness occurred in the PMSGs group; One case of transient blindness and 1 case of brachial artery thrombosis occurred in the perioperative period in the ISF group. During the follow-up period, there was 1 case of distal dissection aneurysm formation in the PMSGs group, and 3 cases of minor typeⅠc endoleak were found after 3 months; One case of subclavian artery stent occlusion and 2 cases of minor typeⅠc endoleak occurred in the ISF group 6 months later. There were no cases of aortic-related deaths during the follow-up period in both groups. There was no statistically significant difference in the technical success rate, incidence of adverse events during the perioperative period and follow-up period, and re-intervention rate between the two groups. The average fluoroscopy time consumed in the ISF group was significantly higher than that in the PMSGs group (34.57 min vs. 21.42 min, P<0.001), but the average hospitalization time in the PMSGs group was significantly higher than that in the ISF group (9.33 days vs. 4.71 days, P<0.001). Conclusion:PMSGs and ISF techniques for reconstructing the left subclavian artery in the treatment of thoracic aortic arch lesions showed good safety and effectiveness. The appropriate fenestration technique selected based on aorta arch anatomical and lesion conditions could achieve satisfactory efficacy in short-term, but long-term effects need to be further observed.

Various etiologies and risk factors contribute to foot pain in children and adolescents, including conditions such as Kohler's disease, Sever's disease, Iselin's disease, rigid flat foot, accessory navicular, Freiberg's disease, sesamoiditis, os trigonum syndrome, and more. High-frequency musculoskeletal ultrasonography can show both the bone surface and the surrounding soft tissue clearly from various angles in real-time, thereby providing a higher level of detail that is helpful for identifying the etiology of foot pain and monitoring disease progression compared with other imaging modalities. This review provides an overview of the epidemiology, pathophysiology, clinical manifestations and characteristic ultrasonographic findings of select foot pain conditions in children and adolescents.

Objective To compare the radiation dose of in vitro pre-fenestration and in situ fenestration thoracic endovascular aortic repair(TEVAR)in treatment of aortic disease.Methods Data of 51 patients with aortic diseases who received in vitro pre-fenestration(group A)and 21 cases who underwent in situ fenestration(group B)TEVAR were retrospectively analyzed.The fluoroscopy duration,total reference air kerma(AK),total dose area product(DAP)and TEVAR time were compared between groups.Results TEVAR was successfully completed in all 72 patients.Fluoroscopy duration([21.42±8.04]min vs.[34.57±9.07]min)and total DAP(44315.0[31157.0,56307.5]μGy·m2 vs.72153.0[45460.0,82354.0]μGy·m2)in group A were both significantly lower than those in group B(both P＜0.05),while total AK(2423[1638,3533]mGy vs.3600[1898,3921]mGy)and TEVAR time([83.41±22.89]min vs.[81.00±22.13]min)in group A were not significant different from those in group B(both P＞0.05).Conclusion Compared with in situ fenestration TEVAR,both the fluoroscopy time and total DAP of in vitro pre-fenestration TEVAR significantly reduced for treating aortic diseases.
