Objective To summarize the clinical characteristics and analyze prognostic factors of neuroblastoma (NB) in infants (≤12 months) at a single center. Methods A retrospective analysis was conducted on the clinical data of infant patients (≤12 months) diagnosed with NB and treated between January 2014 and December 2022. Clinical features were analyzed, and comparisons between two sample rates were performed using the χ² test. Univariate prognostic analysis was conducted using the log-rank test, and survival outcomes were analyzed using the Kaplan-Meier method. Results A total of 42 infants (≤12 months) with NB were enrolled. Low-risk patients underwent surgical resection alone; intermediate-risk patients received surgery combined with chemotherapy with or without maintenance therapy; high-risk patients were treated with surgery and chemotherapy with or without maintenance therapy or radiotherapy. The 5-year event-free survival (EFS) rate was (92.7±4.9)%, and the 5-year overall survival rate was (95.2±3.6)%. Only two patients died because of tumor recurrence or progression. Univariate analysis identified MYCN amplification and the initial lactate dehydrogenase (LDH) level ≥ five times the upper limit of the normal were significantly associated with poor prognosis (5-year EFS: 33.3% vs. 97.4% and 60.0% vs. 97.3%, P<0.0001 and P=0.0035). Conclusion Infant NB has a favorable overall prognosis. MYCN amplification and markedly elevated initial LDH are associated with poor outcomes.

Objective:To investigate the efficacy and safety of hypofractionated radiotherapy combined with temozolomide and bevacizumab in the treatment of primary glioblastoma.Methods:A total of 48 patients who received radiotherapy in Chongqing University Cancer Hospital from Jan. 2020 to Dec. 2023 were enrolled. According to the principle of voluntary participation of patients,research group: hypofractionated radiotherapy+temozolomide+bevacizumab, control group: radiotherapy+temozolomide. The research group received bevacizumab at a dose of 7.5mg/kg, q2w, 1 week before radiotherapy. Hypofractionated radiotherapy (60Gy/20F) was administered with bevacizumab (7.5mg/kg, q2w) combined with temozolomide (75mg/m 2), D1-D42, once a day. Patients would rest for 4 weeks after radiotherapy, and be given bevacizumab (10mg/kg q3w) for 6 cycles until cancer progression and combined with temozolomide (150-200mg/m 2, d1-d5, q28) for 6 cycles. Control group: radiotherapy (60Gy/30F), combined with temozolomide (75mg/m 2) once a day, D1-D42. Patients would rest for 4 weeks after radiotherapy, and be given temozolomide (150-200mg/m 2, d1-d5, q28) for 6 cycles. Both groups were treated until the disease progression or intolerant toxicity. Clinical efficacy evaluation based on neurooncological response evaluation criteria. Results:The total response rate (ORR) in the control group and research group were 37.50% (9 cases/24 cases) and 54.17% (13 cases/24 cases) ; The disease control rate (DCR) ratio was 79.17% (19 cases/24 cases) and 91.67% (22 cases/24 cases) respectively. There were significant differences in ORR and DCR rates between the two groups (all P<0.05). The median OS of patients in the control group and research group were 12.4 months (95% CI: 5.8-9.6) and 18.2 months (95% CI: 8.2-12.4). The median PFS of patients in the control group and research group were 8.9 months (95% CI: 3.8-7.2) and 13.2 months (95% CI: 6.4-10.2). The differences between the two groups were statistically significant ( P<0.05). The incidence of adverse drug reactions in both group was 50.00%, with no statistically difference ( P>0.05) . Conclusion:The newly diagnosed glioblastoma treated with hypofractionated radiotherapy+temozolomide+bevacizumab showed significant advantages compared with conventional radiotherapy in PFS, OS, ORR and DCR.

Aim To explore the mechanism of Jiawei Shaofu Zhuyu decoction in antagonizing endometriosis fibrosis by regulating mitophagy.Methods After the animal model was constructed,the syndrome was evalu-ated by general condition,organ water content and ther-mal imaging.The curative effect was evaluated by the weight of ectopic focus and the degree of adhesion.The pathological changes were compared using HE stai-ning,transmission electron microscopy,Masson and Sir-ius red staining.The expression of PINK1 and Parkin was detected by immunohistochemistry.The expression of mRNA and protein was determined by qPCR and Western blot,and the level of serum ROS was detected by ELISA.Results The autonomic activity of model mice was weakened,the water content of organs rose,and the temperature of limbs and lower abdomen was reduced by thermal imaging.HE staining showed obvi-ous hyperplasia of ectopic epithelium and glands.Transmission electron microscopy showed mitochondrial and endoplasmic reticulum structure damage,and nor-mal autophagy structure disappeared.Masson and Siri-us red staining showed increased collagen deposition;immunohistochemistry showed decreased expression of PINK1 and Parkin in ectopic foci.qPCR and Western blot showed that the expression of PINK1,Parkin,Bec-lin1,LC3 mRNA and protein in ectopic foci of model mice decreased,the expression of p62 mRNA and pro-tein increased,and serum ROS increased.The syn-drome performance of model mice was improved after the intervention of Jiawei Shaofu Zhuyu decoction;the inflammatory infiltration of ectopic foci was relieved,the morphology of mitochondria and endoplasmic retic-ulum was restored,and normal autophagy structure ap-peared.The degree of collagen deposition and fibrosis was reduced;the mRNA and protein expression of PINK1,Parkin,Beclin1 and LC3 increased.The ex-pression of p62 mRNA and protein decreased,and the level of ROS decreased.Conclusions Jiawei Shaofu Zhuyu decoction can improve the fibrosis of ectopic le-sions in mice with endometriosis of cold-dampness sta-sis syndrome,which may be related to the regulation of mitophagy.

Endometriosis(EMs)is a common estrogen-depend-ent clinical disease with the pathological characteristics of malig-nant tumors,which has great impact on women's physical and mental health.In recent years,experimental exploration has re-vealed that ectopic foci are in a hypoxic environment outside the uterine cavity,and mitochondria,as the"functional factories"of the cells,play an important role in the process of planting and in-vasion,and the mitochondrial quality control system,which in-cludes mitochondrial oxidative stress,kinetics,autophagy,bio-genesis and calcium homeostasis,is a key mechanism for the e-quilibrium of the mitochondrial function.The mitochondrial quality control system,including mitochondrial oxidative stress kinetics,autophagy,biogenesis and calcium homeostasis,is a key mechanism for mitochondrial functional balance.Therefore,to clarify the role of the mitochondrial quality control system in the development of EMs with the help of rational and rigorous experi-mental and clinical studies can not only help to clarify the patho-genesis of the disease,but also explore the key targets in the prevention and treatment of the disease.Therefore,this article summarizes the research progress of mitochondrial quality control system in endometriosis,with a view to providing reference and theoretical basis for the etiology,pathogenesis and prevention strategies of EMs.

AIM:To investigate the role of lectin-like oxidized low-density lipoprotein receptor-1(LOX-1)in hypoxia-induced autophagy and apopto-sis in endothelial cells.METHODS:Human umbili-cal vein endothelial cells(HUVECs)were exposed to hypoxia(1％O2)for varying durations(0,6,12,24 h)to evaluate autophagy and apoptosis levels.LOX-1 was further intervened to explore its effects on autophagy and apoptosis.GFP-LC3B adenovirus in-fection was observed under fluorescence microsco-py to assess LC3B expression.Autophagosomes were detected by transmission electron microscopy(TEM).LOX-1 mRNA levels were measured using re-al-time PCR.Protein expression of LOX-1,LC3Ⅱ/Ⅰ,Beclin-1,Atg5,cleaved-caspase 3,Bax,and Bcl-2 was analyzed by Western blot.Reactive oxygen spe-cies(ROS)levels were quantified using the DCFH-DA fluorescent probe.Apoptosis was assessed via Hoechst staining and flow cytometry(Annexin V-PI double staining).RESULTS:Hypoxia(1％O2,24 h)significantly increased LC3Ⅱ puncta under fluores-cence microscopy,upregulated LC3Ⅱ/Ⅰ protein ex-pression,and induced autophagosome formation observed by TEM.Hypoxia elevated ROS produc-tion and promoted apoptosis.LOX-1 mRNA and protein expression were upregulated in hypoxic HU-VECs.LOX-1 siRNA intervention markedly reversed hypoxia-induced autophagy,downregulating au-tophagy-related proteins(Beclin-1,Atg5,LC3Ⅱ/Ⅰ).LOX-1 siRNA also suppressed ROS generation and inhibited apoptosis,as evidenced by decreased ex-pression of cleaved-caspase 3 and Bax,and in-creased Bcl-2 levels.CONCLUSION:Hypoxia in-duced upregulation of LOX-1 expression to produce ROS,thereby promoting autophagy and apoptosis in endothelial cells.

Objective:To explore the efficacy and safety of embolization of anterior cranial fossa dural arteriovenous fistula (ACF-DAVF) via different arterial approaches, and provide evidence for individualized treatment of ACF-DAVF. Methods:A retrospective study was performed; 25 patients with ACF-DAVF admitted to Department of Cerebrovascular Surgery, Neurosurgery Center, Zhujiang Hospital, Southern Medical University from January 2020 to December 2023 were enrolled. Vascular approaches, including the anterior cerebral artery ( n=7), facial artery ( n=3), middle meningeal artery ( n=8), ophthalmic artery ( n=6), and vein ( n=1), were selected based on angioarchitectural features and microcatheter accessibility. Fistula and proximal draining vein occlusions were confirmed by immediate post-embolization digital subtraction angiography (DSA), and perioperative complications were recorded. At a 6-month follow-up, prognoses were assessed by modified Rankin Scale (mRS), and DSA or MRA was performed to detect the recurrence of ACF-DAVF. Results:Six patients had complete embolization and 2 patients had near-total embolization of the fistula and proximal draining vein immediately after embolization via middle meningeal artery approach; 4 patients achieved complete embolization and 2 patients achieved near-total embolization via ophthalmic artery approach; 6 patients achieved complete embolization and one patient achieved near-total embolization via anterior cerebral artery approach; 3 patients achieved complete embolization via facial artery approach; one patient achieved complete embolization via venous approach. No perioperative intracranial hemorrhage or central retinal artery occlusion was noted. Follow-up for 6 months was performed in 25 patients: mRS score was 0 in 19 patients, 1 in 2 patients, and 2 in 4 patients; DSA in 19 patients and MRA in 6 patients indicated no ACF-DAVF recurrence. Conclusion:Based on the angioarchitectural features and microcatheter accessibility, individualized selection of vascular approaches for ACF-DAVF embolization can achieve better efficacy and safety.

OBJECTIVE To evaluate the efficacy， safety and cost-effectiveness of vonoprazan （VPZ） in the treatment of gastroesophageal reflux disease （GERD） by rapid health technology assessment， and provide evidence for clinical decision-making. METHODS English and Chinese databases including PubMed， Medline， Cochrane Library， CNKI， VIP， and Wanfang data as well as the official websites of domestic and international health technology assessment agencies were searched by computer from the database establishment to August 2024. After literature screening， data extraction and quality evaluation of included studies were conducted by two researchers， the results were described and analyzed qualitatively. RESULTS A total of 21 pieces of literature were included， involving 15 systematic reviews/meta-analyses and 6 pharmacoeconomic studies. In terms of efficacy， compared with the control regimen （different doses of VPZ， placebo， other positive controls or combination therapy）， VPZ （mainly 20 mg/d VPZ） significantly improved the total response rate， mucosal healing rate at 2nd week， symptom remission rate， and maintenance rate at 12th and 24th week after mucosal healing （P＜0.05）； when the endoscopic Los Angeles classification was C/D， the effective rate of VPZ was significantly higher than that of the control regimen （P＜0.05）. In terms of safety， there was no significant difference in the incidence of adverse events between VPZ and the control regimen for GERD treatment （P＞0.05）， but the risk of elevated serum gastrin and abnormal liver function caused by long-term use of VPZ was higher than that of the control regimen （P＜0.05）. In terms of cost-effectiveness， compared with rabeprazole， lansoprazole and esomeprazole， VPZ had a cost- effectiveness/cost-utility advantage. CONCLUSIONS VPZ is effective， safe and cost-effective in the treatment of GERD.

ObjectiveWe reviewed the existing experimental studies about renal injury-inducing Chinese medicine and systematically analyzed the toxicity mechanisms， toxic components， toxicity attenuation measures， and modern evaluation methods of renal injury-inducing Chinese medicine. The results are expected to provide new ideas for the modern research on kidney injury-inducing Chinese medicine， offer new breakthrough points for the toxicity attenuation of Chinese medicine by compatibility and processing， and give insights into the future research of Chinese medicine toxicology on the basis of ensuring the safety and scientific application of Chinese medicine. MethodsThe animal， cell， and clinical studies of kidney injury-inducing Chinese medicine were retrieved from CNKI， Wanfang Data， VIP， PubMed， and Web of Science. The names and toxic components of renal injury-inducing Chinese medicine， renal injury sites， toxicity mechanisms， toxicity attenuation measures， and related evaluation methods were summarized. ResultsThe toxicity mechanisms of kidney injury-inducing Chinese medicine mainly involved oxidative stress， endoplasmic reticulum stress， inflammatory cell infiltration， and organic anion transporters. Processing and compatibility were the main toxicity attenuation measures. The evaluation methods encompassed animal experiments， cell models， network pharmacology， metabolomics， toxicology genomics， and fluorescent probe technology. ConclusionAt present， the toxicological verification of kidney injury-inducing Chinese medicine starts from toxic components and combines various experimental methods， which is more comprehensive and systematic than the previous studies based on only animal experiments. According to the classical theories of traditional Chinese medicine， the toxicity of kidney injury-inducing Chinese medicine is mainly attenuated by decocting in water， steaming， and frying. With the progress of science and technology， new processing methods for toxicity attenuation are emerging， and structural transformation， fermentation， and microwave methods are the key research directions of toxicity attenuation of Chinese medicine in recent years.
