Objective:To compare the clinical efficacy and safety of bronchial artery chemoembolization (BACE) combined with anlotinib (BACE+A) versus BACE alone in patients with stage III-IV non-small cell lung cancer (NSCLC).Methods:A total of 94 patients with advanced NSCLC treated at six interventional centers between November 2020 and November 2021 were retrospectively enrolled. Patients were divided into the BACE+A group ( n=46) and the BACE alone group ( n=48) based on treatment regimen. Baseline and perioperative clinical data were collected and compared between the two groups. Treatment response was evaluated using the modified Response Evaluation Criteria in Solid Tumors (mRECIST) at 1, 6, and 12 months after the first BACE procedure. Objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS), overall survival (OS), and treatment-related adverse events (AEs) were recorded. Kaplan-Meier survival curves were plotted to compare median OS and PFS between groups. Cox proportional hazards regression analysis was used to identify factors influencing OS and PFS. Results:The Kaplan-Meier analysis showed that the median OS was significantly longer in the BACE+A group (18.8 months, 95% CI 16.3-21.3) than in the BACE group (13.4 months, 95% CI 11.6-15.2) ( P=0.001). The median PFS was also significantly longer in the BACE+A group (9.0 months, 95% CI 7.3-10.7) compared to the BACE group (6.1 months, 95% CI 4.9-7.3) ( P=0.001). At 6 and 12 months post-first BACE, the ORR (43.5%, 40.0%) and DCR (89.1%, 83.3%) were significantly higher in the BACE+A group than in the BACE group (ORR: 20.8%, 14.8%; DCR: 66.7%, 59.3%) (all P<0.05). Multivariate Cox regression identified treatment with BACE+A ( HR=0.42, 95% CI 0.27-0.72, P=0.002), tumor stage ( HR=1.80, 95% CI 1.05-3.07, P=0.031), presence of pre-existing complications requiring intervention ( HR=2.72, 95% CI 1.65-4.50, P<0.001), and >2 BACE procedures ( HR=0.32, 95% CI 0.15-0.68, P=0.003) as independent factors influencing OS. Treatment with BACE+A ( HR=0.49, 95% CI 0.32-0.76, P=0.001), tumor stage ( HR=1.72, 95% CI 1.07-2.77, P=0.025), multi-arterial tumor blood supply ( HR=2.76, 95% CI 1.76-4.31, P<0.001), and>2 BACE procedures ( HR=0.40, 95% CI 0.22-0.71, P=0.002) were independent factors influencing PFS. There was no significant difference in BACE-related adverse events between the two groups (all P>0.05). Hypertension, fatigue, hand-foot syndrome, and anorexia were common anlotinib-specific adverse reactions in the combination group, but no grade 4 or higher adverse reactions were observed. Conclusions:BACE combined with anlotinib demonstrates superior efficacy compared to BACE alone in treating advanced NSCLC, significantly prolonging OS and PFS. The safety profile is manageable, with adverse events remaining within tolerable limits.

Objective:To explore the preliminary clinical application efficacy of the side branch protection (SBP) technique in single stent-assisted coiling (SSAC) for the treatment of intracranial acute-angulated absolute wide neck bifurcation aneurysms (aWNBA).Methods:The clinical data of 23 patients with aWNBA treated at the Department of Interventional Medicine of the First Affiliated Hospital of Zhengzhou University from January 2013 to June 2024 were retrospectively collected. Patients were divided into two groups based on the stent type used: 11 in the side branch protection (SBP) group and 12 in the double stent-assisted coiling (DSAC) group. The characteristics of aWNBA including the size, the first and second angles between side branches and main artery, and the diameter of aneurysm, were analyzed preoperatively. Stent thromboembolism was recorded during the operation, and Raymond-Roy Occlusion Classification (RROC) and the modified Rankin Scale (mRS) were used to evaluate the treatment efficacy postoperatively. During the follow-up period the RROC and mRS were reevaluated and the stent stenosis was recorded. Mann-Whitney U test was used to compare the two groups′ data of skewed distribution, χ2 test and Fisher′s exact test were used to compare the two groups′ categorical data. Results:The 23 patients with aWNBA included 11 with aneurysms at the bifurcation of the middle cerebral artery, 6 at the top of the basilar artery, and 6 at the bifurcation of the anterior communicating artery. There was no statistically significant difference between the two groups in terms of aWNBA basic characteristics before operation (all P>0.05). The SBP group had a lower incidence of intraoperative stent thromboembolism and a lower mRS postoperatively compared to DSAC group (all P<0.05); meanwhile, there was no statistically significant difference between two groups on RROC after the operation ( P=0.949). During the follow-up period, the SBP group had lower rates of stent stenosis and mRS compared to the DSAC group (all P<0.05) and there was no statistically significant difference between two groups in RROC ( P=0.527). Conclusions:In cases of dense coiling on aWNBA, the SBP technique in SSAC is able to reduce incidence of the stent thromboembolism, stent stenosis as well as neurological injury; therefore, it is a safe and feasible therapeutic strategy for the aWNBA.

Objective This study aims to explore the impact of changes in psychological status on non-suicidal self-inju-ry(NSSI)among junior high school students,in order to provide a theoretical basis for promoting their mental health development and to formulate more effective prevention and intervention measures.Methods A longitudinal study design was employed.Baseline data were collected in 2021(T1)from 652 first-year junior high school students selected through stratified cluster ran-dom sampling from two middle schools in a city.In 2023(T2),585 valid follow-up cases were obtained(effective response rate:89.72％).Chi-square tests,binary logistic regression,and ROC curve analysis were used to examine the effects of dynamic changes in psychological stress,internet addiction,depression,anxiety,and insomnia on NSSI(significance level α=0.05).Results ① Univariate analysis showed that the detection rate of NSSI significantly decreased from 22.05％(129/585)at T1 to 8.55％(50/585)at T2(x2=41.164,P＜0.001),with an average annual decline of 6.75％.Gender differences:the detec-tion rate decreased from 14.68％(43/293)to 5.80％(17/293)in boys(x2=18.577,P＜0.001),and from 29.45％(86/292)to 11.30％(33/292)in girls(x2=5.658,P=0.017),with a narrowing gender gap(T1:14.77％→ T2:5.70％).The NSSI detection rates between boys and girls were statistically significant at both time points(x2=18.577,5.658).② Com-parison between the persistent group and the NSSI-remission group showed that both decreased insomnia severity(OR=3.525,95％CI:1.230-10.105)and increased insomnia severity(OR=5.431,95％CI:1.895-15.570)were associated with an in-creased risk of NSSI persistence or onset(P＜0.01).③ Predictive efficacy:When scores of GAD-7+PHQ-9+ISI all in-creased by≥2 points,AUC=0.709,with a sensitivity of 44.0％-67.7％for predicting NSSI.When PHQ-9+ISI scores both increased by≥2 points,AUC=0.705,with a sensitivity of 50.2％-67.8％.Conclusion This study reveals a high natural re-mission rate of NSSI(82.17％,106/129 in the remission group)during junior high school,but also identifies gender heteroge-neity and persistent risks.Accumulated psychological stress,aggravated internet addiction,and worsened emotional disorders(anxiety/depression)are factors associated with NSSI persistence or onset.Clinical interventions should focus on monitoring dy-namic psychological indicators and early threshold identification.Although these results provide valuable insights,future research is needed to further explore the interaction mechanisms among these factors and how to effectively translate these findings into practical prevention and intervention measures.

Objective To explore the efficiency and safety of trans-sheath intraluminal forceps biopsy under digital subtraction angiography(DSA)guidance for assisting diagnosis of pulmonary artery obstructive diseases.Methods Data of 16 patients who underwent trans-sheath intraluminal forceps biopsy for pulmonary artery obstructive diseases were retrospectively analyzed,and the clinical manifestations were recorded.The technical success of biopsy was defined as tissue obtained met the needs of pathology diagnosis.For patients with malignant pathology results,the final diagnosis was malignant,for those with benign pathology results after biopsy and no obvious changes after 6-month or longer follow-up,or benign pathology results after surgical resection,the final diagnosis was benign,otherwise was no clear diagnosis.The operation time,technical success rate,diagnostic efficiency,complications and changes of pulmonary artery pressure before and after the biopsy were observed.Results Among 16 patients,9 complained of intermittent chest tightness,4 complained of chest pain with chest tightness,2 complained of chest pain but 1 denied any symptoms.The lesions located in the left lung in 10 cases and in the right lung in 6 cases,all with enhanced CT showed filling defects of the involved branch of pulmonary artery.Totally 16 trans-sheath intraluminal forceps biopsies were performed in 16 patients,with an average operation time of(31.02±6.02)min and technical success rate of 100%.Malignant tumors were finally diagnosed in 10 cases,including 1 case of lung cancer with false-negative biopsy result,while biopsy correctly diagnosed benign lesions in the other 6 cases.Transient worsening chest pain with chest tightness occurred in 2 cases and relieved after symptomatic treatments.No statistically significant difference of pulmonary artery pressure was found before([53.38±14.28]mmHg)and after([53.69±14.15]mmHg)biopsy(P＞0.05).Conclusion DSA-guided trans-sheath intraluminal forceps biopsy was relatively safe and valuable for assisting diagnosis of pulmonary artery obstructive diseases.

Objective To discuss the teaching method of staged target teaching(STT)combined with problem-based learning(PBL)in improving the effectiveness of cerebrovascular intervention training.Methods A total of 44 refresher doctors,who received cerebrovascular interventional training at the Department of Interventional Radiology of the First Affiliated Hospital of Zhengzhou University of China between March 2021 and March 2023,were enrolled in this study.Traditional teaching method was adopted for 20 refresher doctors(control group)and STT+PBL teaching method was adopted for the remaining 24 refresher doctors(study group).Before and after the training,the basic theoretical knowledge,operation skill,comprehensive interventional knowledge and the satisfaction survey were compared between the two groups.Results Before training the differences in the basic theoretical knowledge score and learning motivation between the two groups were not statistically significant(P＞0.05).After 6 months training the completion examination score of the study group was significantly better than that of the control group(P＜0.05).Through independently working in clinical practice for one year after training completion,the operation skill,basic theoretical knowledge and comprehensive ability of the study group were remarkably better than those of the control group(P＜0.05).Moreover,the scores of understanding ability,teacher-student interaction,communication skill,clinical thinking ability,self-learning ability,teamwork skill,knowledge mastery degree in the study group were strikingly higher than those in the control group,and the differences were statistically significant(P＜0.05).Conclusion The combination teaching method of STT and PBL can significantly improve the quality and effectiveness of the training on the interventional treatment of cerebrovascular diseases.

Objective:To assess the association between body mass index (BMI) and major adverse cardiovascular and cerebrovascular events (MACCE) among patients with acute coronary syndrome (ACS).Methods:This was a multicenter prospective cohort study, which was based on the Improving Care for Cardiovascular Disease in China (CCC) project. The hospitalized patients with ACS aged between 18 and 80 years, registered in CCC project from November 1, 2014 to December 31, 2019 were included. The included patients were categorized into four groups based on their BMI at the time of admission: underweight (BMI<18.5 kg/m 2), normal weight (BMI between 18.5 and 24.9 kg/m 2), overweight (BMI between 25.0 and 29.9 kg/m 2), and obese (BMI≥30.0 kg/m 2). Multivariate logistic regression models was used to analyze the relationship between BMI and the risk of in-hospital MACCE. Results:A total of 71 681 ACS inpatients were included in the study. The age was (63.4±14.7) years, and 26.5% (18 979/71 681) were female. And the incidence of MACCE for the underweight, normal weight, overweight, and obese groups were 14.9% (322/2 154), 9.5% (3 997/41 960), 7.9% (1 908/24 140) and 7.0% (240/3 427), respectively ( P<0.001). Multivariate logistic regression analysis showed a higher incidence of MACCE in the underweight group compared to the normal weight group ( OR=1.30, 95% CI 1.13-1.49, P<0.001), while the overweight and obese groups exhibited no statistically significant difference in the incidence of MACCE compared to the normal weight group (both P>0.05). Conclusion:ACS patients with BMI below normal have a higher risk of in-hospital MACCE, suggesting that BMI may be an indicator for evaluating short-term prognosis in ACS patients.

Objective:To explore the optimum opportunity for lumbodorsal muscles exercises of patients undergoing posterior lumbar decompression and instrumentation, and investigate its effect on the rehabilitation outcomes and kinesiophobia.Methods:A randomized controlled trial was used. By convenient sampling method, a total of 120 lumbar disc herniation patients were prospectively selected from Affiliated Nantong Hospital of Shanghai(Nantong Sixth People′s Hospital) from February 2020 to December 2021. The paitients were assigned to early group, middle group and late group, with 40 cases in each group. All patients were given routine postoperative care and lumbodorsal muscles exercises. The early group started to exercise 10th day after operation, the middle group started to exercise 3 weeks after operation, and the late group started to exercise 6 weeks after operation. The intervention effect was respectively evaluated by Japanese Orthopaedics Association (JOA) and Tampa Scale for Kinesiophobia (TSK).Results:There were 3, 1 and 1 missing cases in the early, middle and late group respectively, the age in the 3 groups were (56.05 ± 11.77), (57.33 ± 14.64) and (54.23 ± 15.73) years old in turn. Three months after exercising, the total score of JOA in the early, middle and late group were (25.32 ± 2.45), (24.44 ± 2.19) and (22.13 ± 1.58) in turn, the difference was significant ( F=23.64, P<0.05); the score of TSK in the early, middle and late group were (37.95 ± 6.81), (34.18 ± 6.39) and (33.33 ± 7.36) in turn, the difference was significant ( F=4.82, P<0.05). Conclusions:Lumbodorsal muscles exercises start at 3 weeks after operation can significantly improve the rehabilitation outcome of lumbar disc herniation patients undergoing posterior lumbar decompression and instrumentation, and will not increase the level of kinesiophobia, its can be consider as optimum opportunity for lumbodorsal muscles exercises.
