Objective To discuss the effect of simultaneous coronary angiography plus percutaneous coronary intervention(PCI)and selective PCI on the surgical success rate in treating coronary chronic total occlusion(CTO).Methods The clinical data of a total of 147 consecutive patients with coronary CTO,who received PCI treatment at the Jinhua Municipal Central Hospital of China between January 1,2020 and December 31,2022,were retrospectively analyzed.According to whether the patient received PCI immediately after coronary angiography or not,the patients were divided into simultaneous PCI group(n=64)and selective PCI group(n=83).The clinical data and surgical success rate were compared between the two groups.Multivariate logistic regression analysis was used to determine the factors affecting the success of the PCI surgery for coronary CTO.Results The lesion's length of coronary CTO in the simultaneous PCI group was 35 mm,which was obviously shorter than 50 mm in the selective PCI group(P=0.022).No statistically significant differences in the other angiographic findings existed between the two groups(all P＞0.05).The surgical success rate in the simultaneous PCI group was 78.1%,which was remarkably lower than 88.0%in the selective PCI group(P=0.034).Multivariate logistic regression analysis revealed that simultaneous PCI(OR=4.617,95%CI=1.900-11.221,P=0.001),no stump lesion(OR=4.381,95%CI=1.821-10.452,P=0.001),occlusion length≥20 mm(OR=2.462,95%CI=1.030-5.887,P=0.043),and surgical complications(OR=8.688,95%CI=1.573-47.971,P=0.013)were the independent factors influencing the success of PCI surgery for coronary CTO.Conclusion For the treatment of coronary CTO,the simultaneous coronary angiography and PCI treatment may increase the risk of surgical failure.(J Intervent Radiol,2024,32:52-56)

Objective To explore the computed tomography angiography(CTA)and clinical features of Takayasu's arteritis(TA)with peripheral artery involvement.Methods In this retrospective study,CTA scan was performed in a total of 184 TA patients.TA patients were divided into two groups:60 patients within peripheral artery involvement(peripheral artery involvement group)and 124 patients without peripheral artery involvement(peripheral artery non-involvement group).The difference in comparison of clini-cal data and CTA findings were analyzed.Results A total of 194 peripheral arteries were involved in 60 patients.The most suscep-tible peripheral artery were axillary artery(52,26.8％),middle cerebral artery(26,13.4％)and femoral artery(22,11.3％).In the peripheral artery involvement group,the most common CTA manifestation was luminal stenosis(141,72.7％).The lumen dilata-tion,lumen stenosis with dilatation and wall calcification were not easy to be observed.The age and duration of disease in peripheral artery involvement group were significantly greater than those in peripheral artery non-involvement group(P＜0.05).The proportion of the peripheral artery involvement group in the active phase was significantly lower than that of the peripheral artery non-involvement group(P＜0.05).The incidence of pain in the limbs in peripheral artery involvement group was significantly higher than that in peripheral artery non-involvement group(P＜0.05).The utilization rate of tocilizumab in the peripheral artery involvement group was significantly higher than that in the peripheral artery non-involvement group(P＜0.05).Conclusion TA involving peripheral arteries is more common in patients with a long course of disease and in the inactive phase.Patients are prone to pain in their limbs.The CT A manifestations of these patients are also special,that is,the involved peripheral arteries are not prone to lumen dilatation and wall calcification.

Objective To investigate the safety and efficacy of totally no tube three-port thoracoscopic surgery (TNTT) for thymic tumor via lateral thoracic approach. Methods The clinical data of patients with thymoma admitted to the Department of Thoracic Surgery of the General Hospital of Northern Theater Command from November 2021 to May 2022 were retrospectively analyzed. The patients were divided into a TNTT group and a single utility port video-assisted thoracic surgery (SVATS) group according to different surgical methods. The clinical data were compared between the two groups. Results A total of 111 patients were collected. There were 44 patients in the TNTT group, including 20 males and 24 females, with an average age of 60.11±8.64 years, and 67 patients in the SVATS group, including 30 males and 37 females, with an average age of 62.40±7.92 years. There was no significant difference between the two groups in the baseline data (P>0.05). The postoperative hospital stay and intraoperative blood loss were shorter or less in the TNTT group (P<0.05), and the visual analogue scale score 48 hours after the operation was smaller in the SVATS group (P<0.05). Conclusion TNTT has a good surgical safety, and can shorten postoperative hospital stay, reduce intraoperative blood loss, and has significant advantages in enhanced recovery after surgery, but SVATS can reduce postoperative pain in patients.

The universal health coverage agenda promotes population health and social equity and is a priority for the WHO and governments worldwide. This article outlines the basic concept, development, content, monitoring indicators, global progress, and challenges of the universal health coverage agenda. After over half a century of development, a global consensus has been reached on the definition and content of the universal health coverage agenda which emphasizes coverage proportion of the population, content of healthcare services, and economic protection measures. The implementation principle of the agenda for universal health coverage is to prioritize providing healthcare services of high health benefits and social value to the entire population under resource constraints. However, the healthcare service recommendations and evaluation frameworks proposed by the WHO and other international organizations tend to favor low-income countries, neglecting services related to injury prevention and mental health, and therefore may not be suitable for all countries. The development across various dimensions of the agenda for universal health coverage is uneven, with low-income countries lagging. Progress in the prevention and control of non-communicable diseases and injuries is delayed. Low-income groups and vulnerable populations are at a disadvantage in accessing services and economic protection. It is suggested that a globally applicable set of standards, methods, and processes be used to identify high-priority healthcare services. Countries should gradually expand the scope of healthcare services and population coverage based on their needs and capabilities. Additionally, efforts should be made to increase investment in healthcare system resources and international collaboration to promote the development and technological advancement of healthcare systems in low-income countries. Furthermore, it is also necessary to build a high-quality primary healthcare service system and strengthen protection for vulnerable groups.

Objective To investigate the correlation between serum osteoblastin(OPN)and angiopoietin-like protein 8(ANGPTL8)levels and hepatic fibrosis(HF)after interventional therapy-transcatheter arterial chemoembolisation(TACE)in patients with primary hepatocellular carcinoma(PHC).Methods 166 patients with PHC admitted between March 2021 and June 2023 were selected and divided into 92 cases with HF(observation group)and 74 cases without HF(control group)according to whether or not HF occurred after interventional therapy;enzyme-linked immunosorbent assay(ELISA)was used to determine the serum OPN and ANGPTL8 levels and to analyse the predictive value of the OPN and ANGPTL8 levels on HF.Pearson correlation was used to analyze the correlation between OPN and ANGPTL8 levels and biochemical indexes.The factors influencing the occurrence of HF were analyzed by multi-factor Logistics regression.ROC curve was used to analyze the predictive value of OPN and ANGPTL8 for HF.Results Serum OPN[(74.56±11.56)ng/ml],ANGPTL[(42.78±5.23)ng/ml],ALT[(62.24±9.56)U/L],AST[(42.88±8.23)U/L],HA[(252.98±52.44)ng/L],LN[(152.64±26.45)ng/L],PC Ⅲ[(16.54±3.46)ng/L]and Ⅳ-C[(152.78±21.23)ng/L]in observation group were significantly higher than the control group[(57.89±9.68)ng/ml,(35.46±4.78)ng/ml,(49.46±7.46)U/L,(31.48±7.26)U/L,(192.56±23.88)ng/L,(124.48±11.23)ng/L,(11.26±2.23)ng/L and(126.45±18.56)ng/L].The differences between the two groups were statistically significant(P＜0.05).The AUC of serum OPN,ANGPTL8 and the combination of the two in predicting the occurrence of HF were 0.914,0.920 and 0.978,respectively,and the AUC of OPN combined with ANGPTL8 in predicting the occurrence of HF was higher than the AUC of the two separately(P＜0.05).Conclusion The levels of serum OPN and ANGPTL8 of patients with PHC are closely associated with the occurrence of HF,and the two are HF occurrence influencing factors and can be used as indicators to predict the occurrence of HF.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

ObjectiveTo analyze the characteristics of plantar pressure of diabetic patients during gait cycle, and to design a offloading insole with variable stiffness. MethodsThe plantar pressure experiment was carried out and a database including 157 subjects was established. The differences of plantar pressure distribution were analyzed among diabetic patients with and without peripheral neuropathy, and healthy people. The insole pressure area was divided, and porous units were filled in different insole areas according to the pressure gradient. The fed-calf-insole finite element model of diabetic patients was constructed. The simulation analysis of different insole schemes was carried out under the conditions of push-off, footheel-strike and dynamic neutrality posture, and to explore the most reasonable insole stiffness design. ResultsCompared with the healthy group, the percentage of peak pressure and high pressure in the left and right heel areas of diabetic neuropathy patients showed a decreasing trend, in which the left peak pressure was significantly reduced by 11% (P = 0.026) and the percentage of high pressure was significantly reduced by 9.8% (P = 0.02). When the porous elements of 2.5 MPa and 1.9 MPa were used in the high pressure area of the insole metatarsal and high pressure area of the heel, the peak plantar pressure of footheel-strike, dynamic neutral and push-off was reduced by 42.4%, 27.4% and 26.4%, and the peak stress of the soft tissue was reduced by 49.8%, 43.6% and 25.1%, respectively. ConclusionThere is a higher risk of ulcer in the metatarsal region than in the heel region for diabetic patients. The variable stiffness insoles based on the optimization of plantar pressure and internal stress under multi-posture can effectively reduce the peak pressure of plantar and peak stress of soft tissue during walking, which provides a reference for the design of variable stiffness insoles.

OBJECTIVE: To investigate the effect of acetylcorynoline (Ace) for promoting functional recovery of injured spinal cord in rats and explore the underlying mechanism. METHODS: Rat models of spinal cord injury (SCI) were treated with intraperitoneal injection of different concentrations of Ace, with the sham-operated rats as the control group. After the treatment, the changes in motor function of the rats and the area of spinal cord injury were assessed with BBB score and HE staining, and the changes in pro-inflammatory cytokine levels and microglial activation were determined using PCR, ELISA and immunofluorescence staining. In a lipopolysaccharide (LPS)-treated BV2 cell model, the effects of different concentrations of Ace or DMSO on microglial activation and inflammatory cytokine production were observed. Network pharmacology analysis was performed to predict the target protein and signaling mechanism that mediated the inhibitory effect of Ace on microglia activation, and AutoDock software was used for molecular docking between Ace and the target protein. A signaling pathway blocker (Osimertinib) was used to verify the signaling mechanism in rat models of SCI and LPS-treated BV2 cell model. RESULTS: In rat models of SCI, Ace treatment significantly increased the BBB score, reduced the area of spinal cord injury, and lowered the number of activated microglia cells and the levels of pro-inflammatory cytokines (P < 0.05). The cell experiments showed that Ace treatment significantly lower the level of cell activation and the production of inflammatory cytokines in LPS-treated BV2 cells (P < 0.05). Network pharmacology analysis suggested that EGFR was the main target of Ace, and they bound to each other via hydrogen bonds as shown by molecular docking. Western blotting confirmed that Ace inhibited the activation of the EGFR/MAPK signaling pathway in injured mouse spinal cord tissue and in LPS-treated BV2 cells, and its inhibitory effect was comparable to that of Osimertinib. CONCLUSION In rat models of SCI, treatment with Ace can inhibit microglia-mediated inflammatory response by regulating the EGFR/MAPK pathway, thus promoting tissue repair and motor function recovery.

Objective An X-shaped cushioning insole with variable stiffness was designed to explore its effects on plantar pressure and internal stress of diabetic patients with toe amputation. Methods Based on CT images, the feet-calf finite element model of diabetic patients with toe amputation was established, and the insole was divided into different areas according to distribution characteristics of the planter pressure. The three-dimensional (3D) printed cushioning insole with an X-shaped sandwich structure was designed. The modulus of the sandwichstructure was changed by changing thickness of the sandwich structure panel. For simulation analysis, the divided area was filled with the X-shaped sandwich structure with different modulus. Results The peak plantar pressure of diabetic patients with toe amputation was in calcaneal region, and the combined insoles with 1. 2 mpanel thickness in toe area, 1. 4 mm panel thickness in metatarsal area, 2. 0 mm panel thickness in middle area and 1. 6 mm panel thickness in heel area had the best decompression effect. Compared with bare feet, the peak pressure in heel area of the insole, the peak pressure in phalangeal head area and the stress in plantar softissues were reduced by 40. 18% , 31. 7% , and 50. 44% , respectively. Conclusions The 3D printed insoles with variable stiffness can effectively reduce surface pressure and internal stress of the sole and reduce probability of the 2nd toe amputation
