Circulating tumor DNA assisting lymphoma genetic feature profiling and identification.

INTRODUCTION: Lymphoma tissue biopsies cannot fully capture genetic features due to accessibility and heterogeneity. We aimed to assess the applicability of circulating tumor DNA (ctDNA) for genomic profiling and disease surveillance in classic Hodgkin lymphoma (cHL), primary mediastinal large B-cell lymphoma (PMBCL), and diffuse large B-cell lymphoma (DLBCL). METHODS: Tumor tissue and/or liquid biopsies of 49 cHLs, 32 PMBCLs, and 74 DLBCLs were subject to next-generation sequencing targeting 475 genes. The concordance of genetic aberrations in ctDNA and paired tissues was investigated, followed by elevating ctDNA-based mutational landscapes and the correlation between ctDNA dynamics and radiological response/progression. RESULTS: ctDNA exhibited high concordance with tissue samples in cHL (78%), PMBCL (84%), and DLBCL (78%). In cHL, more unique mutations were detected in ctDNA than in tissue biopsies (P < 0.01), with higher variant allele frequencies (P < 0.01). Distinct genomic features in cHL, PMBCL, and DLBCL, including STAT6, SOCS1, BTG2, and PIM1 alterations, could be captured by ctDNA alone. Prevalent PD-L1/PD-L2 amplifications were associated with more concomitant alterations in PMBCL (P < 0.01). Moreover, ctDNA fluctuation could reflect treatment responses and indicate relapse before imaging diagnosis. CONCLUSIONS: Lymphoma genomic profiling by ctDNA was concordant with that by tumor tissues. ctDNA might also be applied in lymphoma surveillance.

Proteomic Landscape Associated with Cognitive Impairment in Individuals with Long-term Methamphetamine Dependence.

BACKGROUND: Methamphetamine (METH) is a highly addictive drug that directly affects the central nervous system. METH use not only harms the user's health but also poses risks and costs to society. Prolonged METH dependence has been shown to impair cognition, which may be the primary factor in impulsive drug-seeking behaviors and high relapse rates. However, the molecular mechanisms underlying METH addiction and METH-induced cognitive decline remain poorly understood. METHODS: To illuminate the potential molecular mechanisms underpinning METH addiction, we compared serum protein expression levels between 12 long-term METH users and 12 healthy controls using label-free quantitative proteomics. Bioinformatic analyses were conducted to determine functional networks and protein-protein interactions. RESULTS: In total, 23 differentially expressed proteins were identified between the two groups. The differentially expressed proteins were related to cognitive dysfunction, neuroinflammation, immune impairment, metabolic disturbances, and calcium binding and regulation. CONCLUSIONS: These 23 proteins may underpin the multi-system damage induced by chronic METH exposure. Our findings provide novel insights into the molecular basis of METH addiction and inform potential prevention and treatment strategies for individuals with METH dependence.

Molecular Biomarker Exploration of Rituximab plus CHOP Therapy in Real-World Diffuse Large B-Cell Lymphoma Patients.

BACKGROUND: Presently, several classification methods are based on diffuse large B-cell lymphoma (DLBCL), but its clinical application has not yet been testified in Asian populations. METHODS: Twenty-five DLBCL patients were subjected to second-generation gene sequencing (NGS), and retrospective analysis of clinical features of the patients was to explore genotyping and survival prognosis biomarkers. RESULTS: The prevalent mutant genes in DLBCL patients cover myeloid differentiation factor 88 (MyD88) (40%), TP53 (32%), B-cell translocation gene 2 (BTG2) (28%), PIM1 (28%), and CREB-binding protein (CREBBP) (24%) in this study. The classical International Prognostic Index (IPI) scores were associated with progression-free survival (PFS) (HR: 7.52, 95% CI 1.51 - 37.6, p = 0.00393) via univariate analysis. Furthermore, patients with ETS-variant gene 6 (ETV6) (HR: 5.1, 95% CI 0.927 - 28.1, p = 0.0371), platelet-derived growth factor receptor A (PDGFRA) (HR: 4.29, 95% CI 0.824 - 22.3, p = 0.0594), platelet-derived growth factor receptor B (PDGFRB) (HR: 10.8, 95% CI 0.979 - 119, p = 0.0149) was distinctively correlated with poor PFS except for the IPI score. Nevertheless, the mutation of PDGFRA/B gene was not distinct in further multivariate analysis (PFS: HR: 2.72, 95% CI 0.52 - 14.23, p = 0.2369). Additionally, better survival prognosis was in DLBCL patients who did not progress within 12 months (POD12). Ultimately, caspase recruitment domain 11 (CARD11) gene mutations were enriched in patients with primary intranodal tumors, but the prognostic relevance was not discovered. CONCLUSIONS: ETV6 and platelet-derived growth factor receptor (PDGFR)A/B gene mutations are supposed to be potential biomarkers for the prognosis of DLBCL patients via the statistical analysis of this small sample, and POD12 is also expected to be an effective endpoint for efficacy assessment.

Covalent Bonding and Coulomb Repulsion-Guided AuNP Array: A Tunable and Reusable Substrate for Metabolomic Characterization of Lung Cancer Patient Sera.

Surface-assisted laser desorption/ionization mass spectrometry (SALDI-MS) has gained increased attention in the metabolic characterization of human biofluids. However, the stability and reproducibility of nanoparticle-based substrates remain two of the biggest challenges in high-salt environments. Here, by controlling the extent of Coulomb repulsion of 26 nm positively charged AuNPs, a homogeneous layer of covalently bonded AuNPs on a coverslip with tunable interparticle distances down to 16 nm has been successfully fabricated to analyze small biomolecules in human serum. Compared with the self-assembled AuNP array, the covalently bonded AuNP array showed superior performances on stability, reproducibility, and sensitivity in high-salt environments. The stable attachment of AuNPs maintained a detection reproducibility with a RSD less than 12% and enabled the reusability of the array for 10 experiments without significant signal deterioration (<15%) and carryover effects. Moreover, the closely positioned AuNPs allowed the coupling of photoinduced plasmons to generate an enhanced electric field, which promotes the generation of excited electrons to facilitate the desorption/ionization processes instead of the heat dissipation, thus enhancing the detection sensitivity with detection limits down to the femtomole level. Combined with machine learning methods, the AuNP array has been successfully applied to discover seven biomarkers for differentiating early-stage lung cancer patients from healthy controls. It is anticipated that this simple approach of developing robust AuNP arrays can also be extended to other types of NP arrays for wider applications of SALDI-MS technology.

Has COVID-19 accelerated the E-commerce of agricultural products? Evidence from sales data of E-stores in China.

We investigated the operation of e-stores specializing in food and agricultural products before and after the occurrence of COVID-19. A difference-in-difference (DID) method was employed to estimate the relationship between COVID-19 and the online sales of agricultural products using data from 164,002 food and agricultural product e-commerce stores (in short, e-stores) of two major Chinese e-commerce platforms in 120 prefectural-level or above cities. The results demonstrated that while COVID-19 and its control measures were associated with a substantial growth in the monthly sales of food and agricultural product e-stores, the growth varies considerably across store scales and with the type of food and agricultural product in which an e-store is specialized. Micro stores experienced much larger growth and played a more important role in maintaining the resilience of the supply chain of food and agricultural products than larger-scale stores; stores selling more essential food items experienced larger growth than those selling leisure food items. A mechanism analysis further revealed that the growth of online sales of agricultural products was mainly driven by changes in consumers' food purchase behaviors from offline channels to online channels (i.e., an increase in the number of online customer orders and price per online order) starting with the onset of COVID-19. The results of this paper underscore the importance of e-commerce in maintaining the resilience of the agri-food supply chain and call for public support of the development of micro- and small-scale e-stores to meet consumers' increasing demand for food supply from those types of stores during the pandemic period.

Pictorial Representation of Illness and Self Measure-Revised 2 (PRISM-R2): an effective tool to assess perceived burden of thyroid cancer in mainland China.

PURPOSE: Thyroid cancer, especially differentiated thyroid cancer (DTC), is a highly prevalent chronic disease that is known to cause considerable distress, related both to the high recurrence and treatment of the disease. The Pictorial Representation of Illness and Self Measure-Revised 2 (PRISM-R2) has been developed as a visual measure to assess suffering. The aim of this study was to evaluate the ability of the instrument to identify patients with DTC with different levels of suffering who may need additional support care. METHODS: Participants were 338 adult inpatients with DTC who were accepting the radioiodine for remnant ablation in the nuclear medicine department. The assessment tools included the following: (1) the PRISM-R2, yielding Self-Illness Separation (SIS) and Illness Perception Measure (IPM); (2) distress thermometer (DT), a measure of thyroid cancer-related distress; (3) posttraumatic growth inventory (PTGI); (4) 12-item Short-Form health survey (SF-12); and (5) the Supportive Care Needs Survey Short Form (SCNS-SF34). In addition, the content validity of PRISM-R2 was tested using the patients' comments. RESULTS: SIS and IPM showed medium intercorrelation (r = -.482; p < 0.01), and both of them showed strongly significant associations with DT. SIS also showed significant correlations with one factor of PTGI (personal strength), four factors of SF-12 (general health, role-emotional, mental health, and vitality), and one factor of SCNS-SF34 (psychological needs). IPM showed significant correlations with five factors of SF-12 and all the factors of SCNS-SF34. No correlation was found between IPM and PTGI. CONCLUSIONS: PRISM-R2 is a well-accepted and understandable tool to assess the psychological burden of patients with thyroid cancer in Chinese settings. It may be useful to guide or evaluate the interventions for the patients.

Neural correlates of breath work, mental imagery of yoga postures, and meditation in yoga practitioners: a functional near-infrared spectroscopy study.

Objective: Previous research has shown numerous health benefits of yoga, a multicomponent physical and mental activity. The three important aspects of both traditional and modern yoga are breath work, postures, and meditation. However, the neural mechanisms associated with these three aspects of yoga remain largely unknown. The present study investigated the neural underpinnings associated with each of these three yoga components in long- and short-term yoga practitioners to clarify the neural advantages of yoga experience, aiming to provide a more comprehensive understanding of yoga's health-promoting effects. Methods: Participants were 40 Chinese women, 20 with a long-term yoga practice and 20 with a short-term yoga practice. Functional near-infrared spectroscopy was conducted while participants performed abdominal breathing, mental imagery of yoga postures, and mindfulness meditation. The oxygenated hemoglobin concentrations activated in the brain during these three tasks were used to assess the neural responses to the different aspects of yoga practice. The self-reported mastery of each yoga posture was used to assess the advantages of practicing yoga postures. Results: Blood oxygen levels in the dorsolateral prefrontal cortex during breath work were significantly higher in long-term yoga practitioners than in short-term yoga practitioners. In the mental imagery of yoga postures task, self-reported data showed that long-term yoga practitioners had better mastery than short-term practitioners. Long-term yoga practitioners demonstrated lower activation in the ventrolateral prefrontal cortex, with lower blood oxygen levels associated with performing this task, than short-term yoga practitioners. In the mindfulness meditation task, blood oxygen levels in the orbitofrontal cortex and the ventrolateral prefrontal cortex were significantly higher in long-term yoga practitioners than in short-term yoga practitioners. Conclusion: The three core yoga components, namely, yogic breathing, postures, and meditation, showed differences and similarities in the activation levels of the prefrontal cortex. Long-term practice of each component led to the neural benefits of efficient activation in the prefrontal cortex, especially in the dorsolateral prefrontal cortex, orbitofrontal cortex, and ventrolateral prefrontal cortex.

Faster, more accurate, more confident? An exploratory experiment on soccer referees' yellow card decision-making.

This study aimed to examine how soccer referees make decisions about issuing yellow cards for fouls. The research involved 60 male participants, divided into expert (n=30) and novice (n=30) groups based on their experience and qualifications as referees. They took part in a 2×2×2 mixed-design experiment. The study looked at Decision-Making Style (DMS: Analytical Decision-Making [ADM] vs. Intuitive Decision-Making [IDM]), Video Type (yellow card foul vs. non-yellow card foul), and Referee Level (expert vs. novice) as independent variables. The dependent variables were accuracy rate (ACC), discrimination index (D), self-confidence index (C), and overconfidence index (OC). The findings showed that Analytical Decision-Making (ADM) led to higher accuracy compared to Intuitive Decision-Making (IDM). Expert referees demonstrated better accuracy than novice referees. There was also an interaction between Decision-Making Style and Referee Level, showing differences in the effectiveness of ADM and IDM between expert and novice referees. Additionally, the study revealed that both expert and novice referees showed overconfidence, with experts demonstrating significantly higher overconfidence, particularly during IDM. In conclusion, the research highlighted the complexity of referees' decision-making in high-pressure situations and emphasized the potential benefits of employing Analytical Decision-Making strategies. The study contributed to understanding cognitive biases in sports officiating and suggested the need for targeted training programs to help referees improve their performance and reduce overconfidence in challenging situations.

EGFR kinase domain duplication in lung adenocarcinoma with systemic and intracranial response to a double-dose of furmonertinib: a case report and literature review.

Background: EGFR kinase domain duplication (EGFR-KDD) is an infrequent oncogenic driver mutation in lung adenocarcinoma. It may be a potential target benefit from EGFR-tyrosine kinase inhibitors (TKIs) treatment. Case presentation: A 66-year-old Chinese male was diagnosed with lung adenocarcinoma in stage IVb with brain metastases. Next-generation sequencing revealed EGFR-KDD mutation. The patient received furmonertinib 160mg daily for anti-cancer treatment and obtained therapeutic efficacy with partial response (PR). Progression-free survival (PFS) duration from monotherapy was 16 months. With slow progressions, combined radiotherapy and anti-vascular targeted therapy also brought a continuous decrease in the tumors. The patient has an overall survival (OS) duration of more than 22 months and still benefits from double-dose furmonertinib. Conclusions: This report provided direct evidence for the treatment of EGFR-KDD to use furmonertinib. A Large-scale study is needed to confirm this preliminary finding.

Validation of the PL-C Quest in China: understanding the pictorial physical literacy self-report scale.

Introduction: The notion of physical literacy is gaining interest from several countries as a potential mechanism for understanding the development of the physical self. This research endeavor represents an inaugural attempt to translate the Australian Physical Literacy Questionnaire for Children (PL-C Quest) into Chinese to evaluate the reliability and validity of the Chinese version of the PL-C Quest to assess physical literacy among children in mainland China. Methods: The Beaton translation paradigm was used to carry out language translation, back-translation, cultural adaptation, and presurveys. Data were collected from 642 children aged 6-12 years, with a mean age of 9.71 years (SD 1.816), to test the reliability of the Chinese version of the PL-C Quest. Results: The PL-C Quest items translated well (6.187 ~ 15.499) and correlated well (0.441 ~ 0.622). The Chinese version of the PL-C Quest had good reliability, with retest reliability values ranging from 0.91 to 0.74, Cronbach's alpha from 0.65 to 0.894, and McDonald's ω from the Spearman-Brown Coefficient was 0.84. The validity results are acceptable because the CFI, IFI, and TLI values are above 0.8 and close to 0.9, but the model fit's chi-square degrees-of-freedom ratio of 2.299, the RMSEA of 0.05, which was less than 0.08. Discussion: After translation and cultural adaptation, the Chinese version of the PL-C Quest is a reliable measurement tool and can be used in the Chinese region.

Hierarchical superstructure aerogels for in situ biofluid metabolomics.

High-throughput biofluid metabolomics analysis for screening life-threatening diseases is urgently needed. However, the high salt content of biofluid samples, which introduces severe interference, can greatly limit the analysis throughput. Here, a new 3-D interconnected hierarchical superstructure, namely a "plasmonic gold-on-silica (Au/SiO2) double-layered aerogel", integrating distinctive features of an upper plasmonic gold aerogel with a lower inert silica aerogel was successfully developed to achieve in situ separation and storage of inorganic salts in the silica aerogel, parallel enrichment of metabolites on the surface of the functionalized gold aerogel, and direct desorption/ionization of enriched metabolites by the photo-excited gold aerogel for rapid, sensitive, and comprehensive metabolomics analysis of human serum/urine samples. By integrating all these unique advantages into the hierarchical aerogel, multifunctional properties were introduced in the SALDI substrate to enable its effective utilization in clinical metabolomics for the discovery of reliable metabolic biomarkers to achieve unambiguous differentiation of early and advanced-stage lung cancer patients from healthy individuals. This study provides insight into the design and application of superstructured nanomaterials for in situ separation, storage, and photoexcitation of multi-components in complex biofluid samples for sensitive analysis.

Prevalence and predictors of posttraumatic growth in accidentally injured patients.

This study examined prevalence and predictors of posttraumatic growth in 180 accidentally injured patients of mainland China in their convalescence stage, investigating its relationships with demographic and accidental injury variables, personality, posttraumatic stress disorder (PTSD) symptoms, and coping styles. Our results showed that posttraumatic growth (PTG) presented mostly in the domain of Relating to Others and indicated that PTG was significantly related to marital status, educational level, personality, coping styles, and PTSD symptoms. Avoidance of PTSD symptoms, Openness to experience, and positive coping were significant predictors of PTG. The findings emphasize that when promoting PTG of accidentally injured patients, healthcare providers should facilitate patients utilizing personal resources, understand PTG coexists with PTSD symptoms, and adjust interventions based on the coping styles the patients have adopted.

Application of action observation therapy in stroke rehabilitation: A systematic review.

BACKGROUND: Numerous studies have described the positive effects of action observation therapy (AOT) on motor recovery among patients with stroke. However, there is no standardized procedure for when and how to intervene with AOT. OBJECTIVES: Thus, we reviewed and analyzed previous studies to provide a guideline for the application of AOT in stroke rehabilitation. METHOD: We searched PubMed, Cochrane Library, and EMBASE from inception to October 31 2022, using title and abstract search terms of "action observation" and "stroke" or "hemiplegia." Of 4108 potential articles, 29 articles (sample size = 429 in AOT groups; sample size = 423 in control groups) that met inclusion criteria were included in final analyses. RESULTS: The results suggested starting adjuvant AOT > 23 days after stroke onset and conducting 30-40 min/session, 3-5 times/week for at least 4 weeks. CONCLUSION: Based on our results, many factors will impact the effect of AOT on stroke rehabilitation, when to apply (timing) and how to apply (frequency, single, and total duration) should be fully considered when applying AOT as adjuvant therapy in stroke rehabilitation.

Identification of Tumor Antigens and Immune Subtypes of High-grade Serous Ovarian Cancer for mRNA Vaccine Development.

High-grade serous ovarian cancer (HGSC) is the most common pathology of ovarian cancer and has aggressive characteristics and poor prognosis. mRNA vaccines are a novel tool for cancer immune treatment and may play an important role in HGSC therapy. Our study aimed to explore tumour antigens for vaccine development and identify potential populations amenable to vaccine treatment. Based on transcription data from The Cancer Genome Atlas (TCGA), we identified four tumour-specific antigens for vaccine production: ARPC1B, ELF3, VSTM2L, and IL27RA. In addition to being associated with HGSC patient prognosis, the expression of these antigens was positively correlated with the abundances of antigen-presenting cells (APCs). Furthermore, we stratified HGSC samples into three immune subtypes (IS1-IS3) with different immune characteristics. A corhort from ICGC (International Cancer Genome Consortium) was used to validate. Patients of IS3 had the best prognosis, while patients of IS1 were most likely to benefit from vaccination. There was substantial heterogeneity in immune signatures and immune-associated molecule expression in HGSC. Finally, weighted gene coexpression network analysis (WGCNA) was employed to cluster immune-related genes and explore potential biomarkers related to vaccination. In conclusion, we identified four potential tumour antigens for mRNA vaccine production for HGSC treatment, and the immune subtype could be an important indicator to select suitable HGSC patients to receive vaccination.

Clinical characteristics, treatment patterns, and survival outcomes of pulmonary mucosa-associated lymphoid tissue lymphoma in the United States.

BACKGROUND: Pulmonary mucosa-associated lymphoid tissue (MALT) lymphoma is a relatively rare disease. We aimed to perform a large-scale study of clinical characteristics and optimal treatment for pulmonary MALT lymphoma patients. METHOD: Our study extracted data from the Surveillance, Epidemiology, and End Results (SEER) Program. The chi-square test was utilized to compare clinical factors. Overall survival (OS) was compared using the Kaplan-Meier (KM) method and Cox regression analysis. Cancer-specific survival (CSS) was compared by the Fine-Gray test. Propensity score matching (PSM) was used to balance confounders. RESULTS: Females and elderly individuals are more likely to suffer from pulmonary MALT lymphoma. The incidence rate is increasing, and most patients are diagnosed in the early stage without specific symptoms. Patients usually suffer from a favorable survival period, especially patients in the early stage. Patients in stage I-II can obtain a survival advantage from surgery, especially for patients older than 60 years, with unilateral lesions, with single-lung-lobe lesions, in stage I, and without B symptoms. Chemotherapy decreases the risk of death for advanced-stage patients, and males, caucasians, patients with stage IV disease, or patients with only unilateral lung involvement were especially recommended for chemotherapy. CONCLUSION: Pulmonary MALT lymphoma is an indolent tumor. Patients in different stages had different prognoses, and different treatments were recommended. We will conduct prospective research in the future.

The combined analysis of urine and blood metabolomics profiles provides an accurate prediction of the training and competitive status of Chinese professional swimmers.

Objective: The purpose of this study was to employ metabolomics for the analysis of urine metabolites in swimmers, with the aim of establishing models for assessing their athletic status and competitive potential. Furthermore, the study sought to compare the identification efficacy of multi-component (urine and blood) model versus single-component (urine or blood) models, in order to determine the optimal approach for evaluating training and competitive status. Methods: A total of 187 Chinese professional swimmers, comprising 103 elite and 84 sub-elite level athletes, were selected as subjects for this study. Urine samples were obtained from each participant and subjected to nuclear magnetic resonance (NMR) metabolomics analysis. Significant urine metabolites were screened through multivariable logistic regression analysis, and an identification model was established. Based on the previously established model of blood metabolites, this study compared the discriminative and predictive performance of three models: either urine or blood metabolites model and urine + blood metabolites model. Results: Among 39 urine metabolites, 10 were found to be significantly associated with the athletic status of swimmers (p < 0.05). Of these, levels of 2-KC, cis-aconitate, formate, and LAC were higher in elite swimmers compared to sub-elite athletes, while levels of 3-HIV, creatinine, 3-HIB, hippurate, pseudouridine, and trigonelline were lower in elite swimmers. Notably, 2-KC and 3-HIB exhibited the most substantial differences. An identification model was developed to estimate physical performance and athletic level of swimmers while adjusting for different covariates and including 2-KC and 3-HIB. The urine metabolites model showed an area under the curve (AUC) of 0.852 (95% CI: 0.793-0.912) for discrimination. Among the three identification models tested, the combination of urine and blood metabolites showed the highest performance than either urine or blood metabolites, with an AUC of 0.925 (95% CI: 0.888-0.963). Conclusion: The two urine metabolites, 2-KC and 3-HIV, can serve as significant urine metabolic markers to establish a discrimination model for identifying the athletic status and competitive potential of Chinese elite swimmers. Combining two screened urine metabolites with four metabolites reported exhibiting significant differences in blood resulted in improved predictive performance compared to using urine metabolites alone. These findings indicate that combining blood and urine metabolites has a greater potential for identifying and predicting the athletic status and competitive potential of Chinese professional swimmers.

[Study of sequence-dependent in vitro effects of zoledronic acid and paclitaxel upon human nasopharyngeal carcinoma cell line HNE1].

OBJECTIVE: To explore the in vitro effects of anti-proliferation and apoptosis-inducing with different sequence regimens of zoledronic acid plus paclitaxel in human nasopharyngeal carcinoma cell line HNE1 so as to explore the optimal sequence regimen of these two drugs and related mechanism. METHODS: The cytotoxic effects of different sequence schemes of zoledronic acid plus paclitaxel on HNE1 cells were detected by methyl-thiazol-tetrazolium (MTT) assay. Annexin V-FITC/PI double staining flow cytometry (FCM) and terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling (TUNEL) assay were used to measure the effects of zoledronic acid plus paclitaxel upon apoptosis. The expressions of mRNA of Bcl-2, Bax, Caspase3 and Caspase9 gene were detected by real-time quantitative-polymerase chain reaction (PCR) and protein was detected by Western blot. RESULTS: All experiment groups enhanced the effect of anti-proliferation by MTT assay (P < 0.05); the treatment of zoledronic acid followed by paclitaxel was superior to the other two regimens (P < 0.05). As detected by FCM, the early apoptotic rate of control group was 2.59% ± 0.28% and the experiment groups were 13.89% ± 0.69%, 11.73% ± 0.54%, 23.97% ± 0.68%, 10.45% ± 0.16% and 8.59% ± 0.74% respectively (P < 0.05). TUNEL assay detected the late apoptosis of HNE1 cells and the experiment groups enhanced the effect of apoptosis-inducing (P < 0.05). The treatment of zoledronic acid followed by paclitaxel was superior to the other regimens (P < 0.05). Such an effect was due to the down-regulation of anti-apoptotic protein Bcl-2 and up-regulations of pro-apoptotic proteins Bax, Caspase3 and Caspase9 at the expression levels of mRNA and protein. There was a greater regulation in the group of zoledronic acid followed by paclitaxel. CONCLUSION: Zoledronic acid can enhance the in vitro effects of anti-proliferation and apoptosis-inducing for paclitaxel on HNE1 cell. The treatment of zoledronic acid followed by paclitaxel may be the optimal regimen. Synergistic induction of apoptosis is via the effects of Bcl-2 family and through the mitochondrial pathway.
