ObjectiveTo investigate the feasibility， safety， and efficacy of surgery-assisted transjugular intrahepatic portosystemic shunt （SA-TIPS） in the treatment of portal hypertension comorbid with complex portal vein thrombosis， including cavernous transformation of the portal vein （CTPV）. MethodsAn analysis was performed for the data of 36 patients with portal hypertension and complex portal vein thrombosis who underwent SA-TIPS in Beijing Shijitan Hospital， Capital Medical University， from November 2023 to January 2025， including general status， technical data of the surgical process （surgical success rate， puncture times， time of operation， the number of stents used， and the length of shunt）， perioperative complications， and surgical recovery. The change in portal pressure gradient （PPG） after shunt was compared， and the rate of reaching the standard for PPG reduction was calculated， as well as stent patency rate within 1 week after surgery. The paired samples t-test was used for comparison of continuous data between two groups. ResultsAmong the 36 patients， 34 （94.4%） underwent SA-TIPS successfully. The incidence rate of perioperative complications was 16.7% （6/36）， including 3 cases of thoraco-abdominal hemorrhage， 2 cases of intraoperative arrhythmia， and 1 case of incision infection. There was a significant reduction in PPG after SA-TIPS （t=19.85， P<0.01）， and the patients achieving a ≥50% reduction in PPG accounted for 76.5% （26/34）. Imaging reexamination within 1 week showed a shunt patency rate of 100%. ConclusionSA-TIPS has a high technical success rate， a favorable safety profile， and good efficacy in the treatment of portal hypertension comorbid with complex portal vein thrombosis （including CTPV）， and therefore， it holds promise for clinical application.

Objective To summarize the clinical features of infectious intracranial aneurysm (IIA) related to infective endocarditis (IE) and share our experiences in the diagnosis and treatment of IIA. Methods A retrospective analysis was conducted on the clinical data of 554 patients who underwent cardiac surgery for IE at the Department of Cardiac Surgery, Guangdong Provincial People's Hospital from September 2018 to August 2023. Patients with secondary IIA were included and reviewed. Based on the treatment strategies, patients were stratified into two groups: an antibiotic-only group and an endovascular treatment group. Results The cohort comprised 21 males and 10 females, with a median age of 33 years (IQR 26-53). Fifteen (48.4%) patients showed no significant neurological symptoms before IIA diagnosis. Seven patients received antibiotic therapy alone, while 24 underwent additional endovascular embolization, achieving technical success in 23 (95.8%) patients. The median interval between endovascular embolization and cardiac surgery was 2 days (IQR 0-6), with 9 patients undergoing concurrent procedures. In the antibiotic-only group, 3 (42.9%) patients suffered fatal IIA rupture. In contrast, only 1 (4.2%) death due to aneurysm rupture occurred in the endovascular treatment group. All surviving patients recovered well without new neurological deficits. Conclusion Routine neuroimaging screening for IIA is critical in IE patients. For those requiring cardiac surgery, endovascular embolization combined with antimicrobial therapy represents a reasonable strategy to mitigate rupture risks and improve outcomes.

Objective:To compare the efficacy and safety of flow diverter (FD) implantation versus stent-assisted coil embolization (SACE) in unruptured saccular aneurysms located at distal segments of the Willis circle.Methods:A retrospective study was performed; 119 patients with unruptured saccular aneurysms located at distal segments of the Willis circle who received FD implantation or SACE in Department of Neurosurgery, Guangdong Provincial People's Hospital, Southern Medical University and Department of Cerebrovascular Surgery, Neurosurgery Center, Southern Medical University from January 2018 to May 2025 were selected. According to different surgical methods, they were divided into a FD group ( n=60) and a SACE group ( n=59). These patients were subjected to propensity score matching (PSM) using 1:1 nearest neighbor matching method to eliminate confounding factors such as gender, age, aneurysm location, and aneurysm diameter (maximum diameter); and then, differences in neurological functional prognosis (good prognosis: modified Rankin scale scores of 0-2), complete aneurysm occlusion rate (O'Kelly-Marotta grade D or Raymond occlusion classification class I), and overall (perioperative and follow-up) complications were compared between the two groups. Results:After PSM, there were 43 patients in both FD group and SACE group. No significant difference was found in clinical and imaging follow-ups (12[6, 19] months vs. 10[6, 15] months, 10[5, 19] months vs. 9[2, 15] months) between the FD group and SACE group ( P>0.05). At the last imaging follow-up, the complete aneurysm occlusion rate in the FD group (65.1%[28/43]) was significantly lower than that in the SACE group (76.7%[33/43], P<0.05). At the last clinical follow-up, no significant difference was noted in good prognosis rate (95.3%[41/43] vs. 97.7%[42/43]) and overall complication rate (30.2%[13/43] vs. 18.6%[8/43]) between the FD group and SACE group ( P>0.05). Conclusion:Both FD implantation and SACE are safe and effective for unruptured saccular aneurysms located at distal segments of the Willis circle; the complete aneurysm occlusion rate within 1 year of FD implantation is relatively low.

Objective To assess the clinical feasibility of a self-developed augmented reality(AR)system in surgeries for cerebral arteriovenous malformation(AVM),dural arteriovenous fistula(DAVF),moyamoya,and internal carotid artery stenosis.This system integrates preoperative vascular imaging(CTA,MRA,DSA)with intraoperative real-time visualization through high-precision patient-image registration and virtual-real integration technology.Methods A retrospective analysis was conducted on 6 patients(1 cerebral AVM,1 DAVF,3 moyamoya and 1 internal carotid artery stenosis)collected between March 2023 and April 2024.AR with three-dimensional reconstruction was used for preoperative precise localization and intraoperative navigation guidance.Clinical feasibility was evaluated and analyzed using an intraoperative self-controlled method.Results All 6 patients with diverse etiologies successfully underwent preoperative precise localization and intraoperative navigation guidance under AR three-dimensional reconstruction modeling.This technology achieved visualization of intracranial arteriovenous structures and precise lesion locations,providing surgeons with a visual reference for accurate planning of the surgical approach and operative field.Conclusion The application of AR with three-dimensional reconstruction is safe and feasible in neurosurgical procedures for cerebrovascular diseases.It demonstrates satisfactory effectiveness in preoperative localization and intraoperative navigation guidance.

This paper summarized the experience of fire needling combined with black cloth ointment in the treatment of keloid. In terms of the pathogenesis of keloid， it is believed that "phlegm causes stasis， and then stasis accumulates into tumors" is the key； the internal obstruction of phlegm and stasis caused by insufficient endowment and invasion of external pathogens is the root of the disease， while the endogenous generation of phlegm and dampness is the branch. It is therefore proposed to explore the etiology and pathogenesis of keloid from the perspective of "phlegm-stasis-tumor"， and the treatment principle is mainly to eliminate phlegm， dispel stasis and dissolve tumors， supplemented with heat-clearing and toxin-resolving. Treatment methods include oral administration of Chinese herbal medicinals and external treatment. Self-made formula for keloid is taken orally， with the main functions of dissolving phlegm， dispelling stasis and clearing heat， to finally dissolve the tumors. For external treatment， fire needling is used to pierce the skin and to open the striae and interstices， and force out the toxin pathogens such as phlegm-heat and stasis-heat with fire power， thereby clearing heat， dissolving phlegm， dispelling stasis and resolving toxins. Black cloth ointment can be used to the affected area to unblock meridians and collaterals， clear heat-toxin and dissolve phlegm-stasis， thereby softening hardness and dissipating masses.

Objective:To verify the predictive value of the Second Revision of the International Staging System (R2-ISS) in newly diagnosed patients with multiple myeloma (MM) who underwent first-line autologous hematopoietic stem cell transplantation (ASCT) in a new drug era in China.Methods:This multicenter retrospective cohort study enrolled patients with newly diagnosed MM from three centers in China (Beijing Chao-Yang Hospital, Capital Medical University; the First Affiliated Hospital, Sun Yat-Sen University, and the Second Affiliated Hospital of Naval Medical University) from June 2008 to June 2018. A total of 401 newly diagnosed patients with MM who were candidates for ASCT were enrolled in this cohort, all received proteasome inhibitor and/or immunomodulator-based induction chemotherapy followed by ASCT. Baseline and follow-up data were collected. The patients were regrouped using R2-ISS. Progression-free survival (PFS) and overall survival (OS) were analyzed. The Kaplan-Meier method was used to analyze the survival curve and two survival curves were compared using the log-rank test. Cox regression analysis were performed to analyze the relationship between risk factors and survival.Results:The median age of the patients was 53 years (range 25-69 years) and 59.5% (240 cases) were men. Newly diagnosed patients with renal impairment accounted for 11.5% (46 cases). According to Revised-International Staging System (R-ISS), 74 patients (18.5 %) were diagnosed with stage Ⅰ, 259 patients (64.6%) with stage Ⅱ, and 68 patients (17.0%) with stage Ⅲ. According to the R2-ISS, the distribution of patients in each group was as follows: 50 patients (12.5%) in stage Ⅰ, 95 patients (23.7%) in stage Ⅱ, 206 patients (51.4%) in stage Ⅲ, and 50 patients (12.5%) in stage Ⅳ. The median follow-up time was 35.9 months (range, 6-119 months). According to the R2-ISS stage, the median PFS in each group was: 75.3 months for stage Ⅰ; 62.0 months for stage Ⅱ, 39.2 months for stage Ⅲ, and 30.3 months for stage Ⅳ; and the median OS was not reached, 86.6 months, 71.6 months, and 38.5 months, respectively. There were statistically significant differences in PFS and OS between different groups (both P<0.001). Multivariate Cox regression analysis showed that stages Ⅲ and Ⅳ of the R2-ISS were independent prognostic factors for PFS ( HR=2.37, 95% CI 1.30-4.30; HR=4.50, 95% CI 2.35-9.01) and OS ( HR=4.20, 95% CI 1.50-11.80; HR=9.53, 95% CI 3.21-28.29). Conclusions:The R2-ISS has significant predictive value for PFS and OS for transplant-eligible patients with MM in the new drug era. However, the universality of the R2-ISS still needs to be further verified in different populations.

Objective Based on the network pharmacology and animal experiments,to investigate the protective effect and possible molecular mechanism of ethanol extract from Atractylodes lancea on liver function in mice with liver fibrosis induced by bile duct ligation.Methods The main active ingredients atractylodin,atractylenolide Ⅰ,Ⅱ and Ⅱ from Atractylodes lancea were selected,which had been verified by literature and experiments,and the targets of these active ingredients were obtained through the SwissTargetPrediction database.The liver fibrosis disease targets were obtained through On-line Mendelian Inheritance in Man (OMIM),DisGeNET and GeneCards databases.The targets were added to the Wei Sheng Xin platform to find the intersection target for Atractylodes lancea in treating liver fibrosis.Cytoscape 3.10.1 was used to construct the "drug-component-target-disease" network diagram and protein-protein interaction core target network diagram.GO functional enrichment analysis and KEGG pathway analysis were performed,and molecular docking was performed between active components and core targets.Liver fibrosis was induced in mice by bile duct ligation,and liver function markers were measured.Results A total of 91 corresponding targets of atractylodin,atractylenolide Ⅰ,Ⅱ and Ⅲ and 9296 liver fibrosis disease targets were obtained,including 74 intersecting targets and 31 core targets.KEGG enrichment analysis showed that the main signaling pathways involved included inflammatory pathways such as epidermal growth factor receptor (EGFR) and phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt).Molecular docking results showed that the active ingredients had strong binding activity with the core target protein.The results of animal experiments showed that,compared with the sham surgery group,the model group displayed notable,the liver index,spleen index,activity of serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST),degree of liver fibrosis,mRNA and protein expression of α-smooth muscle actin (α-SMA) and recombinant collagen type Ⅰ alpha 1 (COL1A1),and mRNA of recombinant collagen type Ⅳ alpha 2 (COL4A2) were significantly increased,and the thymus index was sigficantly decreased (P<0.05);compared with the model group,the liver injury of mice in the Atractylodes lancea administration group reduced liver injury,its liver index,spleen index,activity of serum ALT and AST,degree of liver fibrosis,mRNA and protein expression of α-SMA and COL1A1,and mRNA of COL4A2 were significantly decreased,and the thymus index was sigficantly increased (P<0.05).Conclusion Atractylodes lancea can improve liver function and alleviate tissue pathological damage in mice with liver fibrosis,which may be related to activating pathways such as PI3K/Akt,inhibiting oxidative stress and inflammatory reactions,and intervening in liver fibrosis.

Objective:To understand the prevalence of tobacco use in middle school students in Fujian in 2019 and 2021, explore the influencing factors associated with tobacco use and provide data support for tobacco control intervention.Methods:Two surveys were conducted in middle school students selected through multi-stage stratified clustering random sampling from 10 counties (districts) of Fujian in 2019 and 2021, and χ2 test was used to examine the differences in prevalence of tobacco use between two years, and multiple logistic regression analysis models were used to analyze the factors associated with the tobacco use. Results:The current smoking rate was 2.9% in middle school students in Fujian in 2021, lower than that in 2019 (4.3%). The rate of smoking attempt was higher in 2021 (15.2%) than in 2019 (13.4%). The rate of passive smoking exposure at home, indoor public place, outdoor public place and public transport in 2021 (51.1%) was lower than in 2019 (62.8%), the differences were significant (all P<0.001). In 2021, being vocational school student, passive smoking exposure, believing that smoking is an attractive behavior, believing that smoking is helpful for social contact and seeing other people smoking, including close friends and teachers, were positive associated with tobacco use. Students who believed that passive smoke is harmful and smoking is difficult to quit had lower current smoking rate and smoking attempt rate, respectively. Conclusions:Although the current smoking rate declined in middle school students in Fujian, the smoking attempt rate increased. We should strengthen the establishment of smoke-free campus, health education about tobacco use control to protect adolescents from the harm of tobacco use.
