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.

AIM:To investigate the role of ClC-3 chloride channel in the promotion of radio sensitization of na-sopharyngeal carcinoma CNE-2Z cells by dihydroartemisinin(DHA).METHODS:MTT was used to detect the inhibito-ry effect of DHA on the viability of CNE-2Z cells and normal nasopharyngeal epithelial NP69-SV40T cells,the radio sensi-tization effect of DHA on CNE-2Z cells was detected by cloning assay,the expression of ClC-3 protein was detected by Western blot,the expression of ClC-3 protein was down-regulated by siRNA technology,and the chlorine current of cells was recorded by whole cell patch-clamp technology.RESULTS:(1)Compared with NP69-SV40T cells,DHA selective-ly inhibited the proliferation of CNE-2Z cells,with IC10 values of(13.020±4.831)μmol/L and(5.244±1.050)μmol/L,respectively(P＜0.01).(2)The results of clonal formation experiments showed that DHA had a radio sensitizing effect on CNE-2Z cells,with a radio sensitization ratio of 1.9.(3)DHA could activate the chlorine channel of CNE-2Z cells and produce an outward chlorine current,but had no effect on the chlorine channel of NP69-SV40T cells.(4)DHA promoted the expression of ClC-3 chloric channel protein in CNE-2Z cells(P＜0.01).(5)Chlorine channel blocker NPPB could in-hibit the radio sensitizing effect of DHA on CNE-2Z cells by 1.84 times,and also inhibited the chlorine current activated by DHA.(6)the down-regulation of CNE-2Z ClC-3 protein could inhibit the radio sensitization effect of DHA on CNE-2Z cells by 4.19 times,and the activation of chlorine current by DHA on CNE-2Z cells was no longer produced.CONCLU-SION:DHA has a radio sensitizing effect on nasopharyngeal carcinoma CNE-2Z cells,which is likely to be related to the activation of ClC-3 chloride channel.

Objective:To compare the efficacy and safety of Castor single-branch stent and in vitro fenestration stent in treating thoracic aortic diseases with insufficient landing zone.Methods:The clinical data of patients with thoracic aortic diseases treated with Castor single-branch stent or in vitro fenestrated stent between December 2017 and June 2021 in the First Affiliated Hospital of Zhengzhou University were retrospectively analyzed. A total of 184 patients were included, 99 patients were treated with Castor branch stent, and 85 patients with in vitro fenestration stent. All patients′ general clinical data, surgical data, perioperative and follow-up clinical and imaging data, and postoperative complications were collected. The χ2 test was used to compare the incidence of complications between the two groups, and the Kaplan-Meier method was used to plot the survival rate without adverse events between the two groups. Results:Stent placement was successful in all patients, and the success rate of the technique was 100%. Other branches were reconstructed in 2 patients in the Castor group and double fenestrated stent were reconstructed in 12 patients in the fenestrated group. The mean operation time of the Castor group was significantly shorter than that of the fenestrated group, the number of patients who received local anesthesia was significantly lower than that of the fenestrated group, and the endoleak rate during follow-up was significantly lower than that of the fenestrated group ( P<0.05). There was no significant difference in the postoperative hospital stay, the incidence rate of perioperative complications, mortality, the incidence rate of neurological complications, new dissection or aneurysm rate, branch stent stenosis rate, second surgical intervention rate, and false lumen thrombosis between the two groups ( P>0.05). The adverse event-free survival rate of the Castor group was slightly higher than that of the fenestrated group, but its difference was not statistically significant ( P>0.05). Conclusion:Castor branch stent and in vitro fenestration stent have good short-term and mid-term efficacy in the treatment of aortic diseases with insufficient landing zone, which are safe and effective options for reconstruction of LSA and other branch arteries.

Objective:To investigate the current situation of the use of transjugular intrahepatic portosystemic shunt (TIPS) for portal hypertension, which should aid the development of TIPS in China.Methods:The China Portal Hypertension Alliance (CHESS) initiated this study that comprehensively investigated the basic situation of TIPS for portal hypertension in China through network research. The survey included the following: the number of surgical cases, main indications, the development of Early-TIPS, TIPS for portal vein cavernous transformation, collateral circulation embolization, intraoperative portal pressure gradient measurement, commonly used stent types, conventional anticoagulation and time, postoperative follow-up, obstacles, and the application of domestic instruments.Results:According to the survey, a total of 13 527 TIPS operations were carried out in 545 hospitals participating in the survey in 2021, and 94.1% of the hospital had the habit of routine follow-up after TIPS. Most hospitals believed that the main indications of TIPS were the control of acute bleeding (42.6%) and the prevention of rebleeding (40.7%). 48.1% of the teams carried out early or priority TIPS, 53.0% of the teams carried out TIPS for the cavernous transformation of the portal vein, and 81.0% chose routine embolization of collateral circulation during operation. Most of them used coils and biological glue as embolic materials, and 78.5% of the team routinely performed intraoperative portal pressure gradient measurements. In selecting TIPS stents, 57.1% of the hospitals woulel choose Viator-specific stents, 57.2% woulel choose conventional anticoagulation after TIPS, and the duration of anticoagulation was between 3-6 months (55.4%). The limitation of TIPS surgery was mainly due to cost (72.3%) and insufficient understanding of doctors in related departments (77.4%). Most teams accepted the domestic instruments used in TIPS (92.7%).Conclusions:This survey shows that TIPS treatment is an essential part of treating portal hypertension in China. The total number of TIPS cases is far from that of patients with portal hypertension. In the future, it is still necessary to popularize TIPS technology and further standardize surgical indications, routine operations, and instrument application.

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.
