Objective To investigate the clinical application and safety of DSA-guided infusion port implantation via internal jugular vein,subclavian vein and axillary vein.Methods A total of 827 patients with malignant tumors,who underwent DSA-guided intravenous infusion port implantation at the Jiangyin Municipal People's Hospital of China between March 28,2016 and June 28,2018,were enrolled in this study.According to the used approach in the port implantation,the patients were divided into internal jugular vein group(group A,n=125),subclavian vein group(group B,n=87),and axillary vein group(group C,n=615).The success rate of puncturing and the incidence of complications were compared between each other among the three groups.Results The success rates of the DSA-guided first-time puncturing in group A,B and C were 98.40％(123/125),94.25％(82/87),and 97.89％(602/615)respectively,the difference was statistically significant(P＜0.05);the success rate of puncturing in group B was lower than that in group C,and among the other groups there was no statistically significant difference(P＞0.05).All patients were followed up for a mean period of(15.56±2.91)months(range of 3-26 months).The overall incidence of postoperative early complications was 3.75％,which in group A was 4.00％(5/125),in group B was 9.20％(8/87),and in group C was 2.93％(18/615),and the incidence of complications in group B was obviously higher than that in group C(P＜0.0167).There was no statistically significant difference in the incidence of various complications between each other among the three groups(P＞0.05).The overall incidence of postoperative long-term complications was 4.72％(39/827),which in group A was 4.80％,in group B was 14.95％,and in group C was 3.25％,and the incidence of complications in group B was strikingly higher than that in group A and group C,the difference was statistically significant(P＜0.05).Comparison of groups for the rates of various complications showed that the incidence of catheter fracture in group B was higher than that in group C,and the clipping syndrome occurred only in group B,the difference was statistically significant(P＜0.0167).There was no significant difference in the incidence of other complications between each other among the three groups(P＞0.05).The abnormal port-taking rate was 1.45％,including 3 patients in group A,7 patients in group B,and 2 patients in group C.The postoperative abnormal port-taking rate in group B was the highest(8.05％),which was significantly different from that in group C(P＜0.0167).Conclusion For intravenous infusion port implantation,axillary vein approach is clinically safe,comfortable,minimally-invasive and highly-efficient method,it is superior to internal jugular vein approach and subclavian vein approach in effectively reducing the incidence of complications and improving the postoperative abnormal port-taking rate of patients.Therefore,this technique can be regarded as a first choice in clinical practice.(J Intervent Radiol,2023,32:1212-1216)

Sodium-glucose cotransporter 2 (SGLT2) inhibitors have been reapproved for heart failure (HF) therapy in patients with and without diabetes. However, the initial glucose-lowering indication of SGLT2i has impeded their uses in cardiovascular clinical practice. A challenge of SGLT2i then becomes how to separate their anti-HF activity from glucose-lowering side-effect. To address this issue, we conducted structural repurposing of EMPA, a representative SGLT2 inhibitor, to strengthen anti-HF activity and reduce the SGLT2-inhibitory activity according to structural basis of inhibition of SGLT2. Compared to EMPA, the optimal derivative JX01, which was produced by methylation of C2-OH of the glucose ring, exhibited weaker SGLT2-inhibitory activity (IC₅₀ > 100 nmol/L), and lower glycosuria and glucose-lowering side-effect, better NHE1-inhibitory activity and cardioprotective effect in HF mice. Furthermore, JX01 showed good safety profiles in respect of single-dose/repeat-dose toxicity and hERG activity, and good pharmacokinetic properties in both mouse and rat species. Collectively, the present study provided a paradigm of drug repurposing to discover novel anti-HF drugs, and indirectly demonstrated that SGLT2-independent molecular mechanisms play an important role in cardioprotective effects of SGLT2 inhibitors.

Objective:To analyze the clinical characteristics of adult Chinese patients with syncope.Methods:This is a cross-sectional survey study. Patients with preliminary diagnosis of syncope in the Emergency Department, Geriatrics and Cardiology Outpatient Department, or Syncope Unit of 37 hospitals in 19 provinces, autonomous regions and the Hong Kong Special Administrative Region from June 2018 to March 2021 were included in this study. The clinical features of these patients with syncope were analyzed.Results:A total of 4 950 consecutive patients with syncope were included in this study. The age was (56.3±16.8)years, and 2 604 cases (52.6%) were male. The most common type of syncope was neurally mediated syncope (2 345 (47.4%)), followed by cardiac syncope (1 085 (21.9%)), orthostatic hypotensive syncope (311 (6.3%)), and unexplained syncope accounted for nearly one third (1 155 (23.3%)). Predisposing syncope was more common in patients under 65 years of age(2 066(72.4%) vs. 786(27.6%),χ 2=136.5, P<0.001). Presyncope was more common in patients with neurally mediated syncope (1 972(79.0%) vs.1 908(73.9%), χ 2=17.756, P<0.001). Premonitory symptoms were more common in women(1 837(80.0%) vs. 1 863(73.0%),χ 2=33.432, P<0.001). Presyncope syndrome was more common in patients under 65 years of age (2 482(77.8%) vs. 1 218(73.4%),χ 2=17.523, P=0.001). Cyanosis was more common in ≥65 years old patients (271(18.2%) vs. 369(12.7%), χ 2=23.235, P<0.001). Urinary incontinence was more common in old patients aged ≥65 years(252(15.2%) vs. 345(10.8%), χ 2=19.313, P<0.001). Family history was more common in patients with cardiogenic syncope compared with other types of syncope (264(24.3%) vs. 754(19.5%), χ 2=11.899, P=0.001). Hypertention(1 480(30.5%)), coronary heart disease(1 057(21.4%)), atrial flutter and atrial fibrillation(359(7.2%)), second degree atrioventricular block(236(4.8%)) were common complications of syncope. The proportion of patients with coronary heart disease was significantly higher in cardiac syncope than that of other types of syncope(417(38.4%) vs. 640(16.6%), χ 2=241.376, P<0.001). Other common complications included cerebrovascular diseases (551 (11.1%)) and diabetes mellitus (632(12.8%)). Conclusions:Neurally mediated syncope is the most common syncope in adult Chinese population. Patients with predisposing conditions and premonitory conditions are younger. Presyncope is more common in women. The proportion of family history and coronary heart disease is higher in patients with cardiogenic syncope.

Objective:To investigate the effects of propofol and sevoflurane on post-traumatic stress disorder (PTSD) after emergency surgery in trauma patients.Methods:A total of 160 trauma patients undergoing emergency surgery under general anesthesia were randomly divided into the propofol group and the sevoflurane group. The perioperative clinical data of the two groups were collected. The incidence of PTSD was evaluated by PCL-5 score one month after the operation in the two groups. The relevance of the injury time and PCL-5 score was assessed by Spearman correlation analysis. Logistic regression analysis was used to analyze the risk factors of PTSD.Results:The incidence of PTSD in the propofol group was significantly higher than that in the sevoflurane group at postoperative 1 month (24.0% vs 10.8%, P=0.034). The injury time was negatively correlated with PCL-5 score in the propofol group ( r=0.229, P<0.01). There was no correlation between the injury time and the PCL-5 score in the sevoflurane group ( r=0.001, P=0.804). Logistic regression analysis showed that the use of propofol was an independent risk factor for PTSD ( P=0.004). Conclusions:Sevoflurane anesthesia is more effective than propofol anesthesia in reducing the occurrence of PTSD in emergency surgery for trauma patients.

Objective:To compare the short-term outcomes of segmentectomy for stage ⅠA non-small cell lung cancer by two surgical methods.Methods:A retrospective analysis was performed on 101 patients with stage ⅠA non-small cell lung cancer and undergoing segmentectomy admitted to the Department of Thoracic Surgery of The General Hospital of the Northern Theater Command from July 2016 to July 2020, including 50 patients who underwent Da Vinci robotic segmentectomy and 51 patients who underwent video-assisted thoracoscopic segmentectomy during the same period. By collecting the clinical data of the patients, the operation time, intraoperative blood loss, lymph node dissection stations, lymph node dissection number, drainage volume on the first day after the operation, total drainage volume on the third day after the operation, postoperative chest catheter insertion time, postoperative hospitalization days, and postoperative complication rate were compared and analyzed.Results:Patients in both groups successfully completed pulmonary segmental resection, and there were no cases of conversion to thoracotomy and perioperative death.Compared and analyzed the postoperative clinical results of the two groups, the intraoperative blood loss [(34.40±12.96) ml vs.(85.10±26.41)ml, P=0.000], the number of lymph node dissection stations(4.72±1.20 vs. 3.60±1.40, P=0.000) and the number of lymph node dissection(15.14±5.91 vs. 10.76±5.26, P=0.000) showed statistically significant differences, and RATS group was superior to VATS group.There were no statistically significant differences in operation time[(153.90±21.88) min vs.(155.39±25.04) min, P=0.751], drainage volume on the first day after surgery[(217.80±76.94) ml vs.(210.98±86.98) ml, P=0.678], total drainage volume three days after surgery[(612.60±169.93) ml vs.(595.10±203.90) ml, P=0.641], duration of chest drainage tube after operation[(5.36±2.33) days vs.(5.18±2.54) days, P=0.706], postoperative hospitalization days[(7.50±2.35) days vs.(7.47±2.93) days, P=0.956]and postoperative complication incidence. Conclusion:Da Vinci robot segmentectomy is a safe and effective surgical method, with less bleeding and more lymph node dissection stations and number than video-assisted thoracoscopic segmentectomy for stage ⅠA non-small cell lung cancer.
