Purpose: To evaluate the clinical outcomes of endovascular treatment for ruptured vertebral artery dissecting aneurysms (VADAs), with a focus on endovascular protocols tailored to different anatomical subtypes. Materials and Methods: We retrospectively analyzed 44 consecutive patients with ruptured VADAs treated from December 2014 to October 2024. Treatment strategies were guided by aneurysm location: parent artery occlusion (PAO) was used for lesions in non-dominant VAs, while stent-assisted coiling (SAC) reconstruction was used for aneurysms in dominant VAs. Patients were stratified by modified Rankin Scale (mRS) scores at 3-month follow-up (favorable: mRS 0–2; unfavorable: mRS 3–6). Results: All procedures were technically successful, including 12 single SAC, 13 overlapping SAC, and 19 with PAO (2 involving posterior inferior cerebellar artery preservation). Immediate complete occlusion was achieved in 50.0% of single SAC cases, 76.9% overlapping SAC, and 100% in the PAO group. Six (13.6%) procedure-related complications occurred, including 2 hemorrhagic and 4 ischemic events. Thirty patients (68.2%) had favorable outcomes, and the unfavorable outcomes group showed a higher incidence of ischemic events (P=0.012). An initial poor Hunt–Hess grade (≥IV) was an independent risk factor for unfavorable outcomes (odds ratio 6.35, 95% confidence interval 1.24–32.59; P=0.027). Angiographic follow-up was performed for 34 aneurysms, with complete occlusion achieved in 32 (94.1%); the remaining 2 patients were retreated. Conclusion Endovascular management is safe and effective for ruptured VADAs. Anatomical stratification—PAO for non-dominant VA lesions and SAC for dominant VA aneurysms—may help achieve favorable outcomes.

Objective To investigate the lung protection effect of remazolam under lung protection ventilation strategy in elderly patients undergoing laparoscopic upper abdominal surgery.Methods A prospective randomized controlled study was conducted on 60 patients aged 60 years or older who were scheduled to undergo laparoscopic upper abdominal surgery,including cholecystectomy,common bile duct choledocholithotomy,partial hepatectomy,and subtotal gastrectomy from October 2023 to October 2024.The patients were divided into 2 groups by random number table method:30 patients in the observation group received lung protective ventilation strategy and remazolam administration,and 30 patients in the control group received lung protective ventilation strategy and propofol administration.The inflammatory response indexes(TNF-α,IL-6,and hs-CRP),stress indexes(SOD,NE,and Cor),anesthesia quality(VAS score and Ramsay score),lung function(FVC,FEV1,and MVV％),blood gas indexes(pH,Lac,PaO2,and PaCO2),recovery quality(tracheal tube extubation time,respiratory recovery time,and awakening time),and pulmonary complications were compared between the two groups.Results In the observation group,the serum levels of inflammatory markers of TNF-α,IL-6,and hs-CRP at 2,12,and 24 h postoperatively were all lower than those in the control group(all P=0.000).Regarding stress response indicators,the serum SOD levels in the observation group were higher than those in the control group at 2,12,and 24 h postoperatively,while the NE and Cor levels were lower(all P=0.000).The VAS scores at 24 h postoperatively,and the Ramsay scores at 2 and 24 h postoperatively in the observation group were lower than those in the control group(all P=0.000).In the observation group,the FVC,FEV1,and MVV％were all higher than those in the control group at 48 h postoperatively(P＜0.05).The PaO2 level in the observation group was higher than that in the control group at 24 h postoperatively,and the Lac level was lower(P＜0.05).The respiratory recovery time and awakening time in the observation group were both shorter than those in the control group(P＜0.05).There were no significant differences between the two groups in extubation time and pulmonary complications(P＞0.05).Conclusions The lung protection effect of remazolam under lung protection ventilation strategy is better than that of propofol in elderly patients undergoing laparoscopic upper abdominal surgery.The lung protective effects may be achieved by alleviating perioperative stress response,improving oxygenation function,effective sedation,and reducing inflammatory response.

Background and Aims:Whether to close mesenteric fissures during laparoscopic radical resection of colorectal cancer remains controversial.Traditional suture closure is technically demanding and may injure mesenteric vessels.This study aimed to evaluate the safety and efficacy of using α-cyanoacrylate medical glue to close mesenteric fissures during laparoscopic colorectal cancer surgery.Methods:A retrospective analysis was conducted on patients who underwent laparoscopic radical resection of colorectal cancer in the Department of Colorectal Surgery,the Sixth Affiliated Hospital of Sun Yat-sen University,from January 2022 to December 2023.Seventy-eight patients who received intraoperative α-cyanoacrylate glue closure of mesenteric fissures were included as the observation group,and 74 patients without fissure closure were selected as the control group using the propensity score matching method.Perioperative parameters,postoperative recovery,and complications were compared between the two groups.Results:No significant differences were observed in baseline characteristics or main intraoperative variables between groups(all P>0.05).The observation group had significantly less ascitic drainage within 3 days after operation[(203.14±116.44)mL vs.(384.53±243.89)mL,P<0.01]and shorter postoperative gas passage,defecation,and drainage tube removal times(all P<0.01).The incidence of postoperative complications and intestinal obstruction was comparable between groups(all P>0.05).Multivariate analysis showed that intraoperative application of α-cyanoacrylate glue was an independent promoting factor for intestinal exhaust within 3 days after surgery(OR=5.739,P=0.000).Conclusion:The use of α-cyanoacrylate medical glue for closing mesenteric fissures during laparoscopic radical resection of colorectal cancer is safe and feasible.It effectively reduces postoperative ascitic drainage and accelerates bowel recovery,offering a simple and reliable alternative to traditional suture closure.

Objective:To investigate the distribution of iodine in drinking water and the iodine nutrition status of key populations in Boxing County of Shandong Province, and to provide a basis for continuous elimination of iodine deficiency disorders and scientific iodine supplementation.Methods:In 2021, in the historical iodine deficiency towns (districts, referred to as towns) in Boxing County, one water sample of centralized water supply terminal water of each administrative village (neighborhood committee) was collected for water iodine testing. Using stratified cluster sampling method, the historical iodine deficiency areas in Boxing County were divided into 5 areas according to east, west, south, north and center. One town was randomly selected from each area, 20 pregnant women and 40 non-boarding students aged 8 - 10 from a primary school were randomly selected from each town. Thirty pregnant women and 100 students were selected from each of the two historical high iodine towns, and random urine samples were collected from the above-mentioned population for urinary iodine detection and analysis.Results:A total of 329 water samples were collected, and the median water iodine was 10.9 μg/L. Of these, 267 samples (81.2%) were < 40 μg/L, 33 samples (10.0%) were among 40 - 100 μg/L, and 29 samples (8.8%) were > 100 μg/L. A total of 410 urine samples were collected from children, and the median urinary iodine was 162.0 μg/L. The median urinary iodine of children in different towns was compared, and the difference was statistically significant ( H = 86.34, P < 0.001). A total of 109 urine samples were collected from pregnant women, and the median urinary iodine was 57.4 μg/L. The median urinary iodine of pregnant women in different towns were compared, and the difference was statistically significant ( H = 38.35, P < 0.001). Conclusions:The distribution of iodine in drinking water in Boxing County is complex, with areas with high iodine, iodine deficiency, and suitable iodine sources coexisting. Children's iodine nutrition is at an appropriate level, but pregnant women's iodine nutrition is at a deficiency level. Relevant departments should strengthen health promotion, and each region should formulate iodized salt supply strategies based on actual conditions. At the same time, special attention should be paid to the iodine nutrition status of pregnant women.

Objective To explore the relationship between PANoptosis and hepatic ischemia-reperfusion injury (HIRI), and to screen the key genes of PANoptosis in HIRI. Methods PANoptosis-related differentially expressed genes (PDG) were obtained through the Gene Expression Omnibus database and GeneCards database. Gene ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG), and Gene Set Enrichment Analysis (GSEA) were used to explore the biological pathways related to PDG. A protein-protein interaction network was constructed. Key genes were selected, and their diagnostic value was assessed and validated in the HIRI mice. Immune cell infiltration analysis was performed based on the cell-type identification by estimating relative subsets of RNA transcripts. Results A total of 16 PDG were identified. GO analysis showed that PDG were closely related to cellular metabolism. KEGG analysis indicated that PDG were mainly enriched in cellular death pathways such as apoptosis and immune-related signaling pathways such as the tumor necrosis factor signaling pathway. GSEA results showed that key genes were mainly enriched in immune-related signaling pathways such as the mitogen-activated protein kinase (MAPK) signaling pathway. Two key genes, DFFB and TNFSF10, were identified with high accuracy in diagnosing HIRI, with areas under the curve of 0.964 and 1.000, respectively. Immune infiltration analysis showed that the control group had more infiltration of resting natural killer cells, M2 macrophages, etc., while the HIRI group had more infiltration of M0 macrophages, neutrophils, and naive B cells. Real-time quantitative polymerase chain reaction results showed that compared with the Sham group, the relative expression of DFFB messenger RNA in liver tissue of HIRI group mice increased, and the relative expression of TNFSF10 messenger RNA decreased. Cibersort analysis showed that the infiltration abundance of naive B cells was positively correlated with DFFB expression (r=0.70, P=0.035), and the infiltration abundance of M2 macrophages was positively correlated with TNFSF10 expression (r=0.68, P=0.045). Conclusions PANoptosis-related genes DFFB and TNFSF10 may be potential biomarkers and therapeutic targets for HIRI.

Objective To explore the safety of Yttrium-90 resin microsphere selective internal radiation therapy (⁹⁰Y-SIRT) on malignant liver tumors. Methods A retrospective analysis was conducted on 64 patients with malignant liver tumors who underwent ⁹⁰Y-SIRT from February 2023 to November 2024 at Weifang People’s Hospital. The clinical characteristics of the patients and the occurrence of adverse reactions after treatment were analyzed to assess the safety of ⁹⁰Y-SIRT. Results Among the 64 patients, there were 52 males (81.25%) and 12 females (18.75%); the average age was (56.29±11.08) years. Seven patients (10.94%) had tumors with maximum diameter of less than 5 cm, 38 patients (59.38%) had tumors with maximum diameter of 5-10 cm, and 19 patients (29.68%) had tumors with maximum diameter of greater than 10 cm. There were 47 cases (73.44%) of solitary lesions and 17 cases (26.56%) of multiple lesions; 53 cases (82.81%) were primary liver cancers and 11 cases (17.19%) were metastatic liver cancers. Of the 64 patients, 63 successfully completed the Technetium-99m macroaggregated albumin (^99mTc-MAA) perfusion test and received the ⁹⁰Y-SIRT; one patient received ⁹⁰Y-SIRT after the second ^99mTc-MAA perfusion test due to a work error. The most common adverse reactions included grade 1 alanine aminotransferase (ALT) elevation in 26 cases (40.62%) and grade 2 in 2 cases (9.37%), grade 1 aspartate aminotransferase (AST) elevation in 27 cases (42.18%) and grade 2 in 7 cases (10.93%); grade 1 nausea in 17 cases (26.56%) and grade 2 in 6 cases (9.37%); grade 1 abdominal pain in 12 cases (18.75%), grade 2 in 5 cases (7.81%), and grade 3 in 1 case (1.56%); grade 1 vomiting in 11 cases (17.18%), grade 2 in 5 cases (7.81%), and grade 3 in 1 case (1.56%). Conclusion The adverse reactions of ⁹⁰Y-SIRT for treating malignant liver tumors are mild, indicating good safety.

This review summarizes recent advances in neoadjuvant immunotherapy for advanced gastric cancer.Through literature search in PubMed,Web of Science,and CNKI databases from 2020 to 2023,we systematically analyzed the mechanisms,clinical applications,and bio-marker research.Programmed death-1(PD-1)inhibitors combined with chemotherapy significantly improve patient outcomes,while mi-crosatellite instability(MSI),programmed death-ligand 1(PD-L1)expression,and tumor mutational burden(TMB)have been identified as important predictive biomarkers.Multi-omics analysis shows great potential in identifying optimal responders,with pyroptosis-related gene scoring system(PRS)positively correlating with anti-tumor immune infiltration.Metabolic reprogramming and epigenetic regulation in the tumor microenvironment play key roles in immune evasion,while emerging targets such as Claudin 18.2 and combination targeting strategies further enhance therapeutic efficacy.Despite significant progress,precise patient selection and overcoming resistance mechan-isms remain major challenges.Future research should focus on biomarker validation,personalized treatment strategy development,tumor microenvironment dynamic analysis,and novel combination therapy exploration to improve clinical outcomes.

Objective:To investigate the relationship between thoracic aortic calcification (TAC) and autonomic nervous system (ANS) function in patients receiving continuous ambulatory peritoneal dialysis (CAPD).Methods:It was a cross-sectional study. The CAPD patients with dialysis duration >6 months between January and December 2022 were retrospectively enrolled. The baseline clinical data, heart rate variability (HRV) data such as standard deviation of all normal to normal intervals (SDNN), root mean square of successive differences between adjacent normal-to-normal intervals (RMSSD), high frequency (HF), very low frequency (VLF), low frequency (LF), LF/HF, acceleration capacity (AC) and deceleration capacity (DC), and skin sympathetic nerve activity (SKNA) were collected. TAC was defined as TAC score (TACS) >100 AU. The patients were divided into TACS >100 AU group and TACS≤100 AU group based on whether the thoracic aorta was calcified. The differences of those data between the two groups were compared. Logistic regression model was used to analyze the related factors of TAC. Spearman correlation analysis method was used to analyze the correlation between peripheral blood neuropeptide Y, ANS parameters, average amplitude SKNA (aSKNA) and TACS.　Cox regression model was used to analyze the risk factors of all-cause mortality in patients with CAPD.Results:The study included 106 CAPD patients with 50 males (47.2%), age of (46.04±11.10) years and dialysis duration of (41.55±30.52) months. TACS>100 AU group exhibited significantly lower heart rate ( t=2.015, P=0.046), DC ( t=2.131, P=0.035), LF/HF ( Z=3.332, P<0.001) and ln(LF/HF) ( t=3.326, P=0.001), and higher AC ( t=-2.392, P=0.019) than TACS≤100 AU group. Multivariate logistic regression analysis results showed that after adjusting for age and eosinophil count, lnVLF ( OR=0.66, 95% CI 0.45-0.98, P=0.038), lnLF ( OR=0.69, 95% CI 0.49-0.97, P=0.032), DC ( OR=0.79, 95% CI 0.64-0.99, P=0.039) and AC ( OR=1.32, 95% CI 1.04-1.68, P=0.021) were independently correlated with the risk of TAC. Spearman correlation analysis showed that neuropeptide Y level in peripheral blood was correlated with aSKNA ( r=0.23, P=0.017), lnSDNN ( r=-0.20, P=0.036) and TACS ( r=0.19, P=0.048). During the follow-up period of (25.8±4.2) months, 5 patients (4.72%) died, including 1 patient in the TACS≤100 AU group and 4 patients in the TACS>100 AU group. Compared with the survival group, the death group had higher TACS ( Z=-2.262, P=0.024) and lower LF/HF ( Z=-2.750, P=0.006). Cox regression analysis results showed that increased ln(LF/HF) was an independent influencing factor for all-cause mortality in CAPD patients ( HR=0.22, 95% CI 0.05-0.83, P=0.026). Conclusions:HRV parameters (lnVLF, lnLF, AC and DC) of CAPD patients are independently associated with TAC. The dysfunction of ANS in CAPD patients (especially the decreased vagus nerve activity) may promote TAC.

ObjectiveTo analyze the influencing factors for recurrence in successfully treated pulmonary tuberculosis patients with isoniazid-resistant and rifampicin-sensitive in Shaoxing City, Zhejiang Province. MethodsData on general demographic information, treatment information and drug susceptibility test results for pulmonary tuberculosis patients admitted to the designated tuberculosis medical institutions and registered in the tuberculosis information management system was collected in Shaoxing City from January 2011 to August 2024. A total of 428 patients with isoniazid resistance (including isoniazid single resistance and multiple resistance) but who were successfully treated were included in the study. Information for the recurrence after successful treatment of the patients was analyzed. The Cox proportional hazards models were used to analyze the influencing factors of recurrence in patients. ResultsAmong the 428 successfully treated patients included in the study, 31 cases (accounting for 7.24%) had recurrence by the end of the observation period, with a recurrence rate density of 1.31 per 100 person-years and a median recurrence time of 0.99 (0.08, 8.27) years. Among the relapsed population, 51.61% of the patients relapsed within one year after successful treatment. 77.42% of the patients relapsed within two years after successful treatment. Multivariate Cox regression analysis showed that when isoniazid resistance was discovered, the diagnosis classification of relapse (HR=4.115, 95%CI: 1.734‒9.767) and positive 0-month sequence smear (HR=4.457, 95%CI: 1.053‒18.866) were risk factors for recurrence after successful treatment in patients. ConclusionRegular follow-up should be strengthened for at least two years after the successful treatment of isoniazid-resistant pulmonary tuberculosis patients. Special attention should be paid to the treatment effect and regular re-examination and monitoring after the end of the treatment course of isoniazid-resistant pulmonary tuberculosis patients who have been re-treated and were sputum smear positive at baseline, so as to prevent recurrence and disease progression in high-risk populations.
