Objective To discuss the application value of XperCT combined with needle-guided Glubran-2 glue for small pulmonary nodule localization in thoracoscopic pulmonary nodule resection.Methods The clinical data of 67 patients,who received XperCT combined with needle-guided Glubran-2 glue for small pulmonary nodule localization before thoracoscopic resection of a single small pulmonary nodule at the Jining Municipal First People's Hospital of China between June 2018 and February 2023,were retrospectively analyzed.The size of the pulmonary nodule,the maximum vertical distance from the visceral pleura to the lesion,the technical success rate of localization,the number of puncturing times,the complications,the time spent for operation,and the postoperative pathological diagnosis were recorded.Results The average size of the small pulmonary nodules in the 67 patients was 8.7 mm,and the average vertical distance from the visceral pleura to the lesion was 19.4 mm.Successful preoperative localization of nodule was accomplished in all patients.The average number of puncturing times was 1.1,and no serious complications occurred.The average time spent for operation was 12.7 min.Definite pathological results were obtained in all 67 patients.Conclusion XperCT combined with needle-guided Glubran-2 glue for small pulmonary nodule localization carries advantage of accurate localization with fewer complications.Therefore,this technique is a highly-efficient and quickly-accomplished positioning method,and it is highly valuable in clinical practice.(J Intervent Radiol,2024,33:623-626)

Western bioethics,with its theoretical basis in individualism,is essentially a form of universalist ethics that makes it difficult to respond to the complexities of moral life.Scholars represented by Engelhardt and MacIntyre have profoundly reflected on universalist ethics from the perspective of moral pluralism,but they have not been able to fundamentally resolve the disputes.Grasping the theoretical lineage of the controversy between universalism and particularism can provide an important reference for the construction of bioethics based on Confucianism in contemporary China.Furthermore,from the perspective of opposing universalism and particularism,as well as in response to the issues of the era of life science and technology and the cultural background of China,it can not only realize the modern interpretation of Confucian ethics,but also promote the effective application of modern bioethics theory.

Objective:To investigate the types, incidences, and clinical characteristics of shock in polytrauma patients at different stages after polytrauma.Methods:A retrospective study was conducted on polytrauma patients admitted to multiple trauma centers from June 2020 to December 2021. The inclusion criteria were patients >18 years old and treated due to polytrauma. Exclusion criteria included an admission time of more than 48 h after trauma, a history of malignancy, or metabolic, consumptive, and immunological diseases. The early stage was defined as the period of ≤48 h after polytrauma, and the middle stage was defined as the period between 48 h and 14 days. The patient’s medical history, clinical manifestations, laboratory tests, imaging examination, injury severity score (ISS), and Glasgow coma scale (GCS) were collected. The types, incidences, and clinical characteristics of shock in different stages after polytrauma were analyzed, according to the diagnostic criteria of each type of shock. The differences between the groups were compared by Student’s t test, χ2 test or Mann-Whitney U test. Results:The incidence of the early and middle stage shock after polytrauma were 73.1% and 36.4%, respectively, with statistically significant difference between stages ( P<0.01). There were significant differences in the incidence of hypovolemic shock (83.6% vs. 28.4%), distributed shock (13.7% vs. 80.9%) and cardiogenic shock (3.5% vs. 6.6%) between stages (all P<0.05). The incidence of obstructive shock (8.4% vs. 9.7%, P>0.05) was similar between stages. The incidence of undifferentiated shock was 1.6% and 1.2%, respectively. There were 9.5% patients with multifactorial shock in the early stage and 14.4% in the middle stage. Totally 7 combinations of multifactorial shock were found in different stages after polytrauma. In the early stage, the combination of HS and DS accounted the highest ratio (42.3%) and followed by HS and OS for 28.8%. In the middle stage, the combination of HS and DS was the most common (48.6%) and followed by DS and OS (24.3%). Conclusions:The incidence of shock in polytrauma patients is high. Different types of shock can occur simultaneously or sequentially. Therefore a comprehensive resuscitation strategy is significant to improve the success rate of treatment.

Objective To observe the effect of transcatheter arterial embolization(TAE)with Glubran-2 glue for treating hemorrhage after percutaneous transhepatic cholangial drainage(PTCD).Methods Data of 17 patients with hemorrhage after PTCD who underwent TAE with Glubran-2 glue were retrospectively analyzed.The technical success rate,clinical success rate and complications were observed.The red blood cell(RBC)and hemoglobin(Hb)on the day of TAE and the next day of TAE were compared,also the glutamic-pyruvic transaminase(GPT)level before TAE,on the next day of TAE,on the second and the fourth day after TAE,respectively.Results The offending vessel of bleeding was successfully embolized in all 17 cases,both technical success rate of TAE and clinical success rate of hemostasis were 100%.There was no serious complication such as liver abscess,septicemia nor pulmonary embolism.No significant difference of RBC nor Hb was found between the day of TAE and the next day of TAE(both P＞0.05).GPT before TAE was lower than the next day of TAE and the second day after TAE(P＜0.05),while no significant difference of GPT was found before TAE and 4 days after TAE(P＞0.05).Conclusion TAE with Glubran-2 glue for treating hemorrhage after PTCD was safe and effective.

Urbanization has increased the population density and exposure to environmental risk factors, accelerated changes of people's lifestyles and aggravated population health disparities. A general population cohort in eastern China, Shanghai Suburban Adult Cohort and Biobank (SSACB), was established to understand the incidence and prevalence of chronic and non-communicable diseases, and identify environmental, lifestyle, and genetic risk factors in adults (aged 20-74 years old) living in the suburban of Shanghai, where urbanization process is rapid, and provide evidence for the precise prevention and control of chronic diseases. The cohort study was launched by School of Public Health,Fudan University depended on "Discipline Construction Project Shanghai Peak for Public Health and Preventive Medicine". Four districts in Shanghai, i.e. Songjiang, Jiading, Minhang and Xuhui, were selected. A total of 69 116 permanent residents aged 20-74 years were recruited. Epidemiological investigation, physical examination and laboratory tests were conducted to collect the basic information of the study subjects. Blood and urine samples were collected from them to establish a biobank. An information platform was established, from which the baseline data of the study subjects in electronic medical record system, chronic disease management system, cancer registry, infectious disease reporting system, and death registry can be shared. This paper introduces the design concept, process and future plan of SSACB.

Conversion therapy has become the core in the treatment of borderline resectable or unresectable liver cancer, which provides resectable opportunities for more advanced liver cancer patients. In accordance with the first-choice treatment regimen recommended by the guidelines, the authors reported a successful case of Atezolizumab and Bevacizumab (T+A regimen) conversion therapy. The patient with initially borderline resectable advanced liver cancer was performed liver segment resection sucessfully after conversion therapy, and non-tumor recurrence was observed at postoperative 9 months. Postoperative pathological examination showed combined hepatocellular-cholangiocarcinoma, which also indicated the important value of T+A regimen in the conversion therapy of combined hepatocellular-cholangiocarcinoma.

Objective:To investigate the effect of lncRNA SNHG6 on the proliferation and radiotherapy sensitivity of cervical cancer SiHa cells and its potential mechanism.Methods:The expression levels of lncRNA SNHG6 and miR-485-3p in cervical cancer tissues, paracancer tissues, SiHa cells and SiHa cells exposed to X-ray were detected. The relationship between lncRNA SNHG6 and miR-485-3p was analyzed. After overexpression or knockdown of SNHG6 and miR-485-3p, cell proliferation ability, number of invasion and apoptosis rate were determined by MTT, Transwell chamber assay and flow cytometry, respectively. The effect of miR-485-3p on the Wnt/β-catenin pathway and the effect of XAV939 on SiHa cell proliferation and radiation sensitivity were analyzed.Results:lncRNA SNHG6 was highly expressed in cervical cancer tissues and SiHa cells, whereas was lowly expressed in X-ray irradiated SiHa cells. miR-485-3p was lowly expressed in cervical cancer tissues and SiHa cells, whereas was highly expressed in X-ray irradiated SiHa cells. lncRNA SNHG6 targeted miR-485-3p. Down-regulation of lncRNA SNHG6 expression inhibited cell proliferation and invasion, and enhanced its sensitivity to X-ray radiotherapy, while miR-485-3p inhibitor transfected cells exerted the opposite effect. The up-regulation of lncRNA SNHG6 promoted the proliferation and invasion of SiHa cells through miR-485-3p, and reduced the sensitivity of radiotherapy. Down-regulation of miR-485-3p activated the Wnt/β-catenin pathway, promoted cell proliferation and invasion of SiHa, and reduced its radiation sensitivity to X-ray.Conclusion:Overexpression of lncRNA SNHG6 targeting miR-485-3p activates the Wnt/β-catenin pathway to regulate the proliferation and radiotherapy sensitivity of SiHa cells.

Objective:To summarize our experience in 13 cases of intestinal autotransplantation (IATx) after resection of lesions involving the roots of mesenteric vessels.Methods:The clinical data of 13 patients undergoing IATx in Xijing hospital were retrospectively analyzed. The etiology, surgical procedure and complications were analyzed. The patients were followed up by telephone and regular evaluations.Results:All 13 cases of IATx were successfully completed. For 12 patients who were diagnosed with tumors involving the mesenteric roots, the tumors were removed for cure intent avoiding massive intestinal resection. Pancreaticoduodenectomy was carried out simultaneously in 11 cases. The postoperative complication rate was 85% (11/13). The autograft was resected in 1 patient on the 1st postoperative day due to necrosis from mesenteric thrombosis, leading to short bowel syndrome. One-year survival was 69% (9/13). Among 4 deaths, 1 patient died of liver metastasis, and another died of liver and lung metastases. Five patients were alive 2 years postoperatively.Conclusion:IATx while-technically challenging, avoiding short small bowel syndrome in properly selected patients after resection of lesions especially benign ones involving the roots of mesenteric vessels that were traditionally considered to be "unresectable".

Objective:To investigate the role of autophagy mediated by mTOR signaling pathway in the inhibition of osteogenic differentiation of human bone marrow mesenchymal stem cells (hBMSCs) induced by cadmium.Methods:HBMSCs were divided into 0, 2.5 or 5.0 μmol/L groups according to the exposure dose of cadmium chloride (CdCl 2), and each group was treated for 1 day, 4 days and (or) 7 days. The ALP activity and mRNA and protein expression levels of osteogenesis markers (ALP, RUNX2 and OSTERIX), autophagy-related proteins (LC3 and Beclin-1) and mTOR signaling pathway related proteins (mTOR, p-mTOR and p-p70S6K) expression, alkaline phosphatase staining and alizarin red staining were detected. MHY 1485 was selected as the signaling pathway activator. The control group, CdCl 2 group (5.0 μmol/L), MHY 1485 group and CdCl 2+MHY 1485 combined treatment group were set. After 7 days of treatment, the expression levels of autophagy related proteins and mTOR signaling pathway related proteins of hBMSCs in each group were detected. Results:There was no significant difference in ALP activity between 0, 2.5 and 5.0 μmol/L groups on day 1 and 4 ( P>0.05); On day 7, compared with the 0 μmol/L group, the ALP activity, expression of osteogenic markers (ALP, RUNX2, OSTERIX) and mTOR signaling pathway related proteins (mTOR, p-mTOR, p-p70S6K) expression decreased in the 2.5 and 5.0 μmol/L group ( P<0.05). Compared with the 0 μmol/L group, the staining of the 2.5 and 5.0 μmol/L groups became lighter, and the formation of ALP and mineralized nodules was reduced. Compared with the CdCl 2 group, the autophagy related protein expression in the CdCl 2+MHY 1485 combined treatment group decreased, and the mTOR signaling pathway related protein expression increased. The difference was statistically significant ( P<0.05). Conclusion:The inhibition of osteogenic differentiation of hBMSCs by cadmium may be related to autophagy mediated by mTOR signaling pathway.
