Objective To compare the 12-month efficacy and safety of N-butyl cyanoacrylate (NBCA) versus radiofrequency ablation (RFA) in treating great saphenous vein (GSV) insufficiency. Methods A total of 155 patients with GSV insufficiency from five centers were randomly allocated to the NBCA group or RFA group. Postoperative efficacy and safety outcomes were evaluated. Results Immediate postoperative closure rates of the GSV trunk were 100% in both groups. The closure rates of NBCA and RFA group were 98.6% and 98.5% at 3 months, 97.1% and 98.5% at 6 months, 98.1% and 95.9% at 12 months, with no statistically significant differences (P>0.05). After treatment, CEAP classification improved significantly from baseline in both groups. In terms of safety, 1 case of phlebitis, 1 case of ablation-related thrombus extension (ARTE) and 2 cases of calf muscle venous thrombosis(CMVT) occurred in the NBCA group, while 2 cases of limb numbness, 1 case of persistent thigh pain and 2 cases of CMVT in the RFA group. All reported serious adverse events in both groups were assessed as unrelated to the medical device or the trial procedure. Conclusions NBCA demonstrates non-inferior efficacy and safety compared to RFA for treating GSV insufficiency over 12 months.

Objective To summarize the clinical efficacy of robotic-assisted left thoracic small-incision minimally invasive direct coronary artery bypass grafting(MIDCAB).Methods A retrospective analysis was conducted on the procedures and treatment outcomes of robotic-assisted MIDCAB in the Army Medical Center of PLA from October 2016 to June 2023.Baseline clinical information,MIDCAB-related data,perioperative conditions and data during follow-up were collected and analyzed.Results There were 23 patients subjected,including 21 males and 2 females,with a mean age of 58.17±7.49 years,and a body mass index(BMI)of 23.99±3.25 kg/m2.All of them experienced angina pectoris,and 1 had a history of myocardial infarction,1 had dilated cardiomyopathy,2 patients had chronic obstructive pulmonary disease(COPD),and 10 had a history of percutaneous coronary intervention(PCI).Robotic-assisted MIDCAB procedure was successfully completed.No internal mammary artery injury or transformation of the procedure occurred in these cases,and excellent bridging vessel flow was achieved after anastomosis of the internal mammary artery to left anterior descending branch.The incision length in the left chest was 8(8,8)cm,the operation time was 380(300,465)min,the intraoperative bleeding volume was 300(100,400)mL,the length of ICU stay was 3(2,3)d,the amount of thoracic drainage was 780(525,1 040)mL,and the postoperative length from surgery to discharge was 11.17±2.38 d.No mortality was observed during or within 30 d of hospitalization,and 1 patient was readmitted due to pericardial effusion within 30 d,and was discharged after symptomatic treatment including pericardiocentesis and drainage.No deaths,major adverse cardiovascular and cerebrovascular events(MACCE),or re-revascularization occurred in all patients during outpatient and telephone follow-up.Conclusion Robotic-assisted internal mammary artery dissection is a delicate and safe technique,and coronary artery bypass grafting in minimally invasive small-incision off-pump is effective,safe and feasible,with satisfactory short-and mid-term outcomes.The technique is suitable for minimally invasive coronary artery disease surgery and is worthy of popularization and application.

Objective To explore the relationship between developmental endothelial locus-1(Del-1)and inflammatory response and disease severity in patients with chronic obstructive pulmonary disease(COPD).Method 82 COPD patients admitted to Huai'an Fifth People's Hospital from January 2023 to July 2023 were selected as the COPD group.Among them,40 patients with acute exacerbation were included in the acute exacerbation group,and 42 patients in the stable phase were included in the stable group.Another 40 healthy volunteers who underwent physical examinations during the same period were selected as the control group.The levels of serum Del-1,C-reactive protein(CRP),interleukin-1β(IL-1β)and neutrophil to lymphocyte ratio(NLR)in all study subjects were detected.Pearson's method was used to analyze the correlation between serum Del-1 and inflammatory markers.The predictive value of serum Del-1 for acute exacerbation in COPD patients was analyzed using receiver operating characteristic(ROC)curves.Result The serum CRP,IL-1β and NLR levels in the COPD group were higher than those in the control group(t=12.047,13.107,9.404),the serum Del-1 level in the COPD group was 386.87±42.34 pg/ml,lower than that in the control group 512.63±60.21 pg/ml(t=13.343),and the differences were statistically significant(all P<0.05).The serum CRP,IL-1β and NLR levels in the acute exacerbation group were higher than those in the stable group(t=4.170,5.292,5.919),the serum Del-1 level in the acute exacerbation group was 347.64±40.69 pg/ml,lower than that in the stable group 424.23±48.31 pg/ml(t=7.746),and the differences were statistically significant(all P<0.05).Pearson analysis showed that the serum Del-1 level in COPD patients were negatively correlated with serum CRP,IL-1β and NLR levels(r=-0.534,-0.587,-0.612,all P<0.05).ROC analysis showed that serum Del-1 had a high predictive value for acute exacerbation in COPD patients,with an AUC(95%CI)of 0.886(0.812～0.960).When the optimal cutoffvalue was 380.65 pg/ml,the sensitivity and specificity were 82.50%and 85.00%,respectively.Conclusion Serum Del-1 is low expression in COPD patients and is ngeatively correlated with their inflammatory response and disease severity,it is expected to become a new biomarker for predicting the risk of acute exacerbation of COPD.

Objectives:To evaluate the tricuspid valve(TV)geometric remodeling in patients with idiopathic pulmonary arterial hypertension(IPAH)by three-dimensional transthoracic echocardiography. Methods:Two-dimensional and three-dimensional transthoracic echocardiography were performed in 30 IPAH patients and 15 healthy controls,and the geometry parameters of TV were obtained by four-dimensional auto tricuspid valve quantitative(4D Auto-TVQ)in the right ventricular-focused apical view.Pulmonary arterial hypertension was determined by right heart catheterization within 48 hours of echocardiography. Results:The 4-chamber diameter,tricuspid annular(TA)perimeter,TA area,maximal tenting height,coaptation point height and tenting volume were larger in IPAH patients than those in healthy controls(all P＜0.05),2-chamber diameter was similar between two groups.In IPAH group,maximal tenting height and coaptation point height were moderately correlated with right ventricular end-diastolic volume(r=0.710,r=0.515,both P＜0.05),while TA perimeter,4-chamber diameter and TA area were moderately correlated with right atrial end-systolic volume(r=0.712,r=0.558,r=0.545,all P＜0.05). Conclusions:IPAH patients have larger maximal tenting height,coaptation point height and tenting volume,TA enlargement is mainly visible in 4-chamber diameter.TV tenting height is associated with right ventricular volume,but TA size is associated with right atrial volume in IPAH patients.

Neck dissection(ND)is one of the main treatment methods for oral and maxillofacial malignancies.Although ND type is in con-stant improvement,but intraoperative peal-pull-push injury of the accessory nerve,muscle,muscle membrane,fascia and ligament induced shoulder syndrome(SS)is still a common postoperative complication,combined with the influence of radiochemotherapy,not only can cause pain,stiffness,numbness,limited dysfunction of shoulder neck and arm,but also may have serious impact on patient's life quality and phys-ical and mental health.At present,there is still a lack of a systematic evaluation and rehabilitation management program for postoperative SS of oral and maxillofacial malignant tumors.Based on the previous clinical practice and the current available evidence,refer to the relevant lit-erature at home and abroad,the experts in the field of maxillofacial tumor surgery and rehabilitation were invited to discuss,modify and reach a consenusus on the etiology,assessment diagnosis,differential diagnosis,rehabilitation strategy and prevention of SS,in order to provide clinical reference.

Background and purpose:Effective treatment for cervical cancer patients is one of the global strategies to eliminate cervical cancer.By analyzing the metastasis characteristics and survival status of patients with distant metastasis of cervical cancer from a hospital-based cancer registry data,our study provided real-world evidence for better survival of cervical cancer and finally eliminating cervical cancer.Methods:A total of 572 cervical cancer patients who had metastasis cancer at the initial diagnosis or developed distant metastasis during follow-up in Fudan University Shanghai Cancer Center from 2008 to 2017 were included in this study.Medical records review,telephone visits and death registry data linkage were applied in collecting endpoint data.The first follow-up date was the diagnose date of metastasis,and the last follow-up date was November 1,2020.Kaplan-Meier method was applied in evaluating the 1-,3-and 5-year overall survival(OS)rates for overall and site-specific patients.Results:The median follow-up time was 38.93 months,and 348 cases died during the follow-up.72.55%were single site metastasis,and 27.45%were multiple metastases.Among all metastatic sites,the proportion of lung metastasis was the highest,41.26%,15.21%to bone,and 11.54%to liver.After metastasis,the 1-year,3-year and 5-year OS rates were 62.29%(95%CI:62.25-62.33),33.13%(95%CI:33.08-33.18)and 23.42%(95%CI:23.37-23.47),respectively.In single site metastasis,1-year OS was the highest after metastasis to the lung(72.52%).Besides,there was no significant difference among different metastatic sites,both in 3-year and 5-year OS.Conclusion:The most frequent distant metastatic sites of cervical cancer are lung,bone and liver.The survival rate after metastasis is poor.Further research with systematic treatment strategy is required for better survival.
