OBJECTIVE: To compare the effects of bilateral vertebral puncture guided by an angle-adjustable linear laser auxiliary device versus free-hand bilateral vertebral puncture. METHODS: A retrospective analysis was conducted on the clinical data of 47 patients who underwent thoracolumbar percutaneous kyphoplasty(PKP) from July 2022 to July 2023. All patients received bilateral percutaneous kyphoplasty, among whom 27 cases underwent conventional free-hand puncture (conventional puncture group) and 20 cases underwent puncture guided by a laser auxiliary device (auxiliary puncture group). In the conventional puncture group, there were 11 males and 16 females, with an average age of (69.6±5.1) years and a disease duration of (6.5±3.8) days;the fractured vertebrae were T₁₁-T₁₂ in 13 cases and L₁-L₂ in 14 cases. In the auxiliary puncture group, there were 7 males and 13 females, with an average age of (70.8±5.6) years and a disease duration of (6.4±3.8) days;the fractured vertebrae were T₁₁-T₁₂ in 7 cases and L₁-L₂ in 13 cases. The operation time, total blood loss, intraoperative fluoroscopy times, fluoroscopy duration, radiation dose, puncture success rate, and surgical complications were compared between the two groups. The visual analogue scale (VAS) was used to evaluate low back pain before surgery, 2 days after surgery, and 1 year after surgery. RESULTS: All patients achieved successful puncture, with good postoperative wound healing and no complications. The operation time of the auxiliary puncture group was (12.1±2.6) minutes, which was shorter than that of the conventional puncture group (14.1±2.8) minutes. The total blood loss of the auxiliary puncture group was (228.5±35.8) ml, less than that of the conventional puncture group (257.0±48.3) ml. The fluoroscopy times, fluoroscopy duration, and radiation dose of the auxiliary puncture group were (5.4±1.3) times, (15.9±3.3) seconds, and (159.4±37.4) μSv, respectively, all lower than those of the conventional puncture group (6.4±1.6) times, (18.8±4.6) seconds, (192.2±48.5) μSv, with statistically significant differences(P<0.05). There were no statistically significant differences in low back VAS scores between the two groups before surgery, 2 days after surgery, or 1 year after surgery(P>0.05). CONCLUSION Both laser auxiliary device-guided vertebral puncture and free-hand vertebral puncture have high success rates and similar postoperative curative effects. However, the laser auxiliary device-guided puncture has shorter operation time, less blood loss, and lower radiation hazard.

Objective To investigate the role of poly(rC)-binding protein 1(PCBP1)in cadmium(Cd)-induced ferroptosis in mouse neuroblastoma Neuro-2a(N2A)cells.Methods N2A cells were exposed to a concentration gradient of CdCl?(0,1,2,4 μmol/L)for 72 h.Cell viability was assessed by trypan blue staining.Western blotting was employed to detect the expression of ferroptosis-related proteins(GPX4,HMOX1,ACSL4)and PCBP1.Intracellular Fe2? level and lipid peroxidation were detected using FerroOrange and BODIPY581/591 C11 probes,respectively.Ferrostatin-1(Fer-1),a ferroptosis inhibitor,was applied to confirm the critical role of ferroptosis in Cd-induced cytotoxicity.Molecular docking was performed to elucidate the interaction between PCBP1 and ferritin,as well as the binding sites of Cd2?.PCBP1 overexpression plasmid was further constructed for functional validation.Results Cd exposure suppressed cell viability in N2A cells in a dose-dependent manner(P<0.01),significantly down-regulated GPX4 expression(P<0.05),up-regulated HMOX1 expression(P<0.01),and induced Fe2? overload and lipid peroxidation(P<0.01).Molecular docking revealed that Cd2? directly bound to the KH2 domain of PCBP1 and then co-localized on the outer surface of ferritin heavy chain.Overexpression of PCBP1 markedly reversed Cd-induced Fe2? accumulation,GPX4 down-regulation,lipid peroxidation,and cell death.Conclusion Cd exposure disrupts PCBP1-mediated iron homeostasis via transcriptional suppression and competitive displacement of metal ions,and then synergistically drives Fe2? overload-triggered ferroptosis cascades,ultimately leading to neurotoxicity.Targeting PCBP1-mediated iron homeostasis can effectively mitigate Cd-induced neurotoxicity,and may serve as a novel therapeutic strategy.

Background::Although some well-established oncogenes are involved in cancer initiation and progression such as prostate cancer (PCa), the long tail of cancer genes remains to be defined. Goosecoid ( GSC) has been implicated in cancer development. However, the comprehensive biological role of GSC in pan-cancer, specifically in PCa, remains unexplored. The aim of this study was to investigate the role of GSC in PCa development. Methods::We performed a systematic bioinformatics exploration of GSC using datasets from The Cancer Genome Atlas, Genotype-Tissue Expression, Gene Expression Omnibus, German Cancer Research Center, and our in-house cohorts. First, we evaluated the expression of GSC and its association with patient prognosis, and identified GSC-relevant genetic alterations in cancers. Further, we focused on the clinical characterization and prognostic analysis of GSC in PCa. To understand the transcriptional regulation of GSC by E2F transcription factor 1 ( E2F1), we performed chromatin immunoprecipitation quantitative polymerase chain reaction (qPCR). Functional experiments were conducted to validate the effect of GSC on the tumor cellular phenotype and sensitivity to trametinib. Results::GSC expression was elevated in various tumors and significantly correlated with patient prognosis. The alterations of GSC contribute to the progression of various tumors especially in PCa. Patients with PCa and high GSC expression exhibited worse progression-free survival and biochemical recurrence outcomes. Further, GSC upregulation in patients with PCa was mostly accompanied with higher Gleason score, advanced tumor stage, lymph node metastasis, and elevated prostate-specific antigen (PSA) levels. Mechanistically, the transcription factor, E2F1, stimulates GSC by binding to its promoter region. Detailed experiments further demonstrated that GSC acted as an oncogene and influenced the response of PCa cells to trametinib treatment. Conclusions::GSC was highly overexpressed and strongly correlated with patient prognosis in PCa. We found that GSC, regulated by E2F1, acted as an oncogene and impeded the therapeutic efficacy of trametinib in PCa.

This study analyzed and compared the epidemiological characteristics of foodborne listeriosis in the United States and China,to provide evidence for optimizing the listeriosis surveillance program in China.Descriptive statistical analysis was performed on the listeriosis monitoring data from 2009 to 2021 registered in the FDOSS system and the attribution estimates of Listeria monocytogenes(L.monocytogenes)from 2013 to 2021 published by IFSAC.Sporadic and outbreak data on listeriosis in China from the CNKI,Wanfang Medical,and CQVIP databases were collected.From 2009 to 2021,a total of 1 037 listeriosis cases were reported in the United States,including 902 hospitalizations and 165 deaths.The peak of cases caused by Lm con-taminated food was in July.The number of cases,hospitalizations,and deaths accounted for 18.4％(191/1 037),20.5％(185/902),and 22.4％(37/165)of the total,respectively.Most listeriosis outbreaks were attributed to three food groups:dairy products,vegetable crops,and fruits,with attribution percentages ranging from 73.8％to 89.6％.The overall incidence of list-eriosis in China was not high:619 cases were reported from 2009 to 2021,and only 177 cases were recorded in detailed inci-dence years;the maximum number of cases in 2018 was 26.A total of 220 cases were reported with detailed onset months;the highest number of cases in April was 30.Data on listeriosis cases in China are incomplete and sporadic,and only seven cases have been successfully traced to food.Listeriosis surveillance systems in the United States are relatively complete,and there are more foodborne outbreaks.Dairy products,vegetable row crops,and fruits are the most likely causes of disease outbreaks.Although only sporadic cases have been reported in China,China should take actions such as gradually improving multi-department coop-eration mechanisms,achieving data sharing and deepening data mining,and accelerating progress in the detection technology of food-borne pathogenic microorganisms,to ensure food safety and public health.

Objective:To analyze the effects of highdose methotrexate(HD-MTX)and lenalidomide as central nervous system(CNS)prophylaxis strategies in patients with diffuse large B-cell lymphoma(DLBCL).Methods:The data of DLBCL patients with high risk of CNS recurrence who were initially treated in Fujian Provincial Hospital and Fujian Cancer Hospital from January 2012 to June 2022 were analyzed retrospectively.The patients were divided into HD-MTX group and lenalidomide group according to different prophylaxis strategies.Each group was further divided into high-risk group and medium-risk group based on CNS-IPI score and/or testicular involvement.The CNS relapse-free survival(CRFS)rate,adverse effects,and the effects of different prophylaxis strategies on overall survival(OS)rate and progression-free survival(PFS)rate were evaluated in different groups and subgroups.Results:There were 200 patients enrolled in this study,80 cases in lenalidomide group and 120 cases in HD-MTX group.According to the delivery timing of prophylactic HD-MTX,the patients in HD-MTX group were further divided into two groups:80 cases at the end of induction chemotherapy and 40 cases during chemotherapy interval.At a median follow-up of 48(14-133)months,the 4-year CRFS rate,4-year PFS rate,and 4-year OS rate of the HD-MTX group was 93.6％,57.2％,and 68.8％,respectively,while that of the lenalidomide group was 90.4％,69.4％and 75.6％.There were no significant differences in 4-year CRFS rate,4-year PFS rate,and 4-year OS rate between HD-MTX group and lenalidomide group(all P＞0.05),but lenalidomide group showed a trend of improvement in PFS.Further subgroup analysis showed that there was no significant difference in 4-year CRFS rate between high-risk patients of the two groups(91.7％vs 83.4％,P＞0.05),while 4-year PFS rate showed difference(49.5％vs 64.2％,P＜0.05).A total of 248 cycles were collected for adverse reaction analysis in the HD-MTX group,and 25 cycles occurred neutropenia accompanied with infection(10.1％),while in lenalidomide group 240 cycles were collected in which 20 cycles occurred neutropenia accompanied with infection(8.3％).Both the two groups had no treatment-related deaths.Conclusion:Compared with HD-MTX,lenalidomide combined with immunochemotherapy can prevent CNS relapse,at the same time,improve prognosis,which is a safe and well tolerated central prophylaxis strategy.

Objective To evaluate the cost-utility of tiotropium/olodaterol in treating Chinese patients with moderate to very severe chronic obstructive pulmonary disease(COPD)and to provide references for selecting more economical inhaled preparations in clinical practice.Methods A four-state lifetime Markov model was established with a 3-month cycle.The health outcomes included life years and quality-adjusted life years.Costs,including direct medical costs,were calculated from the perspective of the Chinese health system.Discontinuation rates were derived from the discontinuation curve using GetData Graph Digitizer.The main output indicator of the model was the incremental cost-utility ratio,which was calculated from the queue simulation results to judge the economy of tiotropium bromide/odataterol.The scenario analysis and sensitivity analyses were carried out to detect the robustness of the base case result.Results Compared with tiotropium bromide,the patient treated with tiotropium bromide/odataterol gained an additional 0.0846 life years,an additional cost of ￥3 201.50,and additional 0.029 6 QALY.The incremental cost-utility ratio was 108 140.11 yuan/QALY,lower than the willingness-to-pay threshold of three times China's per capita GDP in 2021.The costs of tiotropium bromide and tiotropium bromide/odataterol had the greatest impact on the result in the one-way sensitivity analysis.93.8%of the Chinese COPD population was willing to pay for tiotropium bromide/odataterol under the threshold in the probability sensitivity analysis.Conclusion Tiotropium/olodaterol is a cost-effective alternative compared to tiotropium for patients with moderate to very severe COPD in China and the results were robust in the sensitivity analyses.

Objective: To explore the application and efficacy of paclitaxel liposome in the treatment of advanced breast cancer among Chinese population in the real world. Methods: The clinical characteristics of patients with advanced breast cancer who received paclitaxel liposome as salvage treatment from January 1, 2016 to August 31, 2019 in 11 hospitals were collected and retrospectively analyzed. The primary outcome was progression free survival (PFS), and the secondary outcome included objective response rate (ORR) and safety. The survival curve was drawn by Kaplan-Meier analysis and the Cox regression model were used for the multivariate analysis. Results: Among 647 patients with advanced breast cancer who received paclitaxel liposome, the first-line treatment accounted for 43.3% (280/647), the second-line treatment accounted for 27.7% (179/647), and the third-line and above treatment accounted for 29.1% (188/647). The median dose of first-line and second-line treatment was 260 mg per cycle, and 240 mg in third line and above treatment. The median period of paclitaxel liposome alone and combined chemotherapy or targeted therapy is 4 cycles and 6 cycles, respectively. In the whole group, 167 patients (25.8%) were treated with paclitaxel liposome combined with capecitabine±trastuzumab (TX±H), 123 patients (19.0%) were treated with paclitaxel liposome alone (T), and 119 patients (18.4%) were treated with paclitaxel liposome combined with platinum ± trastuzumab (TP±H), 108 patients (16.7%) were treated with paclitaxel liposome combined with trastuzumab ± pertuzumab (TH±P). The median PFS of first-line and second-line patients (5.5 and 5.5 months, respectively) were longer than that of patients treated with third line and above (4.9 months, P<0.05); The ORR of the first line, second line, third line and above patients were 46.7%, 36.8% and 28.2%, respectively. Multivariate analysis showed that event-free survival (EFS) and the number of treatment lines were independent prognostic factors for PFS. The common adverse events were myelosuppression, gastrointestinal reactions, hand foot syndrome and abnormal liver function. Conclusion: Paclitaxel liposomes is widely used and has promising efficacy in multi-subtype advanced breast cancer.

OBJECTIVE: Arsenic (As) and fluoride (F) are two of the most common elements contaminating groundwater resources. A growing number of studies have found that As and F can cause neurotoxicity in infants and children, leading to cognitive, learning, and memory impairments. However, early biomarkers of learning and memory impairment induced by As and/or F remain unclear. In the present study, the mechanisms by which As and/or F cause learning memory impairment are explored at the multi-omics level (microbiome and metabolome). METHODS: We stablished an SD rats model exposed to arsenic and/or fluoride from intrauterine to adult period. RESULTS: Arsenic and/fluoride exposed groups showed reduced neurobehavioral performance and lesions in the hippocampal CA1 region. 16S rRNA gene sequencing revealed that As and/or F exposure significantly altered the composition and diversity of the gut microbiome，featuring the Lachnospiraceae_NK4A136_group, Ruminococcus_1, Prevotellaceae_NK3B31_group, [Eubacterium]_xylanophilum_group. Metabolome analysis showed that As and/or F-induced learning and memory impairment may be related to tryptophan, lipoic acid, glutamate, gamma-aminobutyric acidergic (GABAergic) synapse, and arachidonic acid (AA) metabolism. The gut microbiota, metabolites, and learning memory indicators were significantly correlated. CONCLUSION Learning memory impairment triggered by As and/or F exposure may be mediated by different gut microbes and their associated metabolites.
