RESUMO

Teclistamab, an off-the-shelf B-cell maturation antigen (BCMA) × CD3 bispecific antibody that mediates T-cell activation and subsequent lysis of BCMA-expressing myeloma cells, is approved for the treatment of patients with relapsed/refractory multiple myeloma (RRMM). As a T-cell redirection therapy, clinical outcomes with teclistamab may be influenced by patient immune fitness and tumor antigen expression. We correlated tumor characteristics and baseline immune profiles with clinical response and disease burden in patients with RRMM from the pivotal phase 1/2 MajesTEC-1 study, focusing on patients treated with 1.5 mg/kg of teclistamab (N = 165). Peripheral blood samples were collected at screening and bone marrow samples were collected at screening and cycle 3. Better clinical outcomes to teclistamab correlated with higher baseline total T-cell counts in the periphery. In addition, responders (partial response or better) had a lower proportion of immunosuppressive regulatory T cells, T cells expressing co-inhibitory receptors (CD38, PD-1, PD-1/TIM-3), and soluble BCMA, and a T-cell profile suggestive of a more cytolytic potential, compared with nonresponders. Neither frequency of baseline bone marrow BCMA expression nor BCMA receptor density were associated with clinical response to teclistamab. Improved progression-free survival was observed in patients with a lower frequency of T cells expressing exhaustion markers and immunosuppressive regulatory T cells. Overall, response to teclistamab was associated with baseline immune fitness; nonresponders had immune profiles suggestive of immune suppression and T-cell dysfunction. These findings illustrate the importance of the contribution of the immune landscape to T-cell redirection therapy response. This trial was registered at www.ClinicalTrials.gov, NCT03145181/NCT04557098.

RESUMO

Oxidative stress is associated with a variety of disease pathologies, it may lead to mitochondrial dysfunction, damage of impaired DNA repairment, cell damage or apoptosis. Acupuncture and moxibustion therapy has been proved to have a role in reducing oxidative stress in organisms under pathological conditions. In the present paper, we collected literatures in both English and Chinese from domestic and foreign databases on the mechanisms of acupuncture and moxibustion underlying amelioration of oxidative stress over the past 5 years, and analyzed the link between acupuncture-moxibustion intervention and redox biology from four aspects: 1) regulation of the production of reactive oxygen species (ROS), 2) affecting antioxidant enzyme-related pathways to reduce ROS, 3) repairing proteins, lipids and DNAs attacked by ROS, and 4) inhibiting downstream apoptosis or autophagy of ROS pathway. By summarizing and prospecting such antioxidant mechanisms, this paper may provide some basis and ideas for in-depth mechanism research on acupuncture and moxibustion to improve oxidative stress and related diseases.

RESUMO

INTRODUCTION: Patients with relapsed or refractory multiple myeloma (RRMM) report significantly lower HRQoL compared with patients with newly diagnosed MM and experience further deterioration in HRQoL with each relapse and subsequent treatment. Therefore, consideration of the impact of treatment on HRQoL in addition to clinical outcomes is vital. PATIENTS AND METHODS: In the phase I/II MajesTEC-1 (NCT03145181, NCT04557098) study, patients with RRMM who received teclistamab, an off-the-shelf, T-cell redirecting BCMA × CD3 bispecific antibody, had deep and durable responses with manageable safety. HRQoL was assessed using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire core 30-item and the EuroQol 5 Dimension 5 Level descriptive questionnaire. Changes over time from baseline were measured with a repeated measures mixed-effects model. Proportions of patients with clinically meaningful improvement after starting treatment and time to clinically meaningful worsening were assessed. RESULTS: Compliance was maintained throughout the study. Compared with baseline, positive changes were observed for pain, global health status, and emotional functioning with treatment; other assessments were largely unchanged from baseline. Post hoc analysis showed patients with deeper clinical response generally reported improved HRQoL outcomes. Following an initial decline in HRQoL in some scales, the proportion of patients reporting clinically meaningful improvements increased, while the proportion reporting clinically meaningful worsening decreased over time. Clinically meaningful improvements in pain were reported in ≥40% of patients at most assessment time points. CONCLUSIONS: These results complement previously reported clinical benefits and support teclistamab as a promising therapeutic option for patients with RRMM.

RESUMO

INTRODUCTION: Teclistamab is the first approved B cell maturation antigen × CD3 bispecific antibody with precision dosing for the treatment of triple-class exposed (TCE) relapsed/refractory multiple myeloma (RRMM). We compared the effectiveness of teclistamab in MajesTEC-1 versus real-world physician's choice of therapy (RWPC) in patients from the prospective, non-interventional LocoMMotion and MoMMent studies. METHODS: Patients treated with teclistamab from MajesTEC-1 (N = 165) were compared with an external control arm from LocoMMotion (N = 248) or LocoMMotion + MoMMent pooled (N = 302). Inverse probability of treatment weighting adjusted for imbalances in prognostic baseline characteristics. The relative effect of teclistamab versus RWPC for overall response rate (ORR), very good partial response or better (≥ VGPR) rate, and complete response or better (≥ CR) rate was estimated with an odds ratio using weighted logistic regression transformed into a response-rate ratio (RR) and 95% confidence interval (CI). Weighted proportional hazards regression was used to estimate hazard ratios (HRs) and 95% CIs for duration of response (DOR), progression-free survival (PFS), and overall survival (OS). RESULTS: Baseline characteristics were well balanced between treatment cohorts after reweighting. Patients treated with teclistamab had significantly improved outcomes versus RWPC in LocoMMotion: ORR (RR [95% CI], 2.44 [1.79-3.33]; p < 0.0001), ≥ VGPR (RR 5.78 [3.74-8.93]; p < 0.0001), ≥ CR (RR 113.73 [15.68-825.13]; p < 0.0001), DOR (HR 0.39 [0.24-0.64]; p = 0.0002), PFS (HR 0.48 [0.35-0.64]; p < 0.0001), and OS (HR 0.64 [0.46-0.88]; p = 0.0055). Teclistamab versus RWPC in LocoMMotion + MoMMent also had significantly improved outcomes: ORR (RR 2.41 [1.80-3.23]; p < 0.0001), ≥ VGPR (RR 5.91 [3.93-8.88]; p < 0.0001), ≥ CR (RR 132.32 [19.06-918.47]; p < 0.0001), DOR (HR 0.43 [0.26-0.71]; p = 0.0011), PFS (HR 0.49 [0.37-0.66]; p < 0.0001), and OS (HR 0.69 [0.50-0.95]; p = 0.0247). CONCLUSION: Teclistamab demonstrated significantly improved effectiveness over RWPC in LocoMMotion ± MoMMent, emphasizing its clinical benefit as a highly effective treatment for patients with TCE RRMM.

RESUMO

BACKGROUND: Teclistamab, a B-cell maturation antigen × CD3 bispecific antibody, is approved in patients with relapsed/refractory multiple myeloma (RRMM) who have previously received an immunomodulatory agent, a proteasome inhibitor, and an anti-CD38 antibody. OBJECTIVE: We report the population pharmacokinetics of teclistamab administered intravenously and subcutaneously (SC) and exposure-response relationships from the phase I/II, first-in-human, open-label, multicenter MajesTEC-1 study. METHODS: Phase I of MajesTEC-1 consisted of dose escalation and expansion at the recommended phase II dose (RP2D; 1.5 mg/kg SC weekly, preceded by step-up doses of 0.06 and 0.3 mg/kg); phase II investigated the efficacy of teclistamab RP2D in patients with RRMM. Population pharmacokinetics and the impact of covariates on teclistamab systemic exposure were assessed using a 2-compartment model with first-order absorption for SC and parallel time-independent and time-dependent elimination pathways. Exposure-response analyses were conducted, including overall response rate (ORR), duration of response (DoR), progression-free survival (PFS), overall survival (OS), and the incidence of grade ≥ 3 anemia, neutropenia, lymphopenia, leukopenia, thrombocytopenia, and infection. RESULTS: In total, 4840 measurable serum concentration samples from 338 pharmacokinetics-evaluable patients who received teclistamab were analyzed. The typical population value of time-independent and time-dependent clearance were 0.449 L/day and 0.547 L/day, respectively. The time-dependent clearance decreased rapidly to < 10% after 8 weeks of teclistamab treatment. Patients who discontinue teclistamab after the 13th dose are expected to have a 50% reduction from Cmax in teclistamab concentration at a median (5th to 95th percentile) time of 15 days (7-33 days) after Tmax and a 97% reduction from Cmax in teclistamab concentration at a median time of 69 days (32-163 days) after Tmax. Body weight, multiple myeloma type (immunoglobulin G vs non-immunoglobulin G), and International Staging System (ISS) stage (II vs I and III vs I) were statistically significant covariates on teclistamab pharmacokinetics; however, these covariates had no clinically relevant effect on the efficacy of teclistamab at the RP2D. Across all doses, ORR approached a plateau at the concentration range associated with RP2D, and in patients who received the RP2D, a flat exposure-response curve was observed. No apparent relationship was observed between DoR, PFS, OS, and the incidence of grade ≥3 adverse events across the predicted exposure quartiles. CONCLUSION: Body weight, myeloma type, and ISS stage impacted systemic teclistamab exposure without any clinically relevant effect on efficacy. The exposure-response analyses for ORR showed a positive trend with increasing teclistamab systemic exposure, with a plateau at the RP2D, and there was no apparent exposure-response trend for safety or other efficacy endpoints. These analyses support the RP2D of teclistamab in patients with RRMM. CLINICAL TRIAL REGISTRATION: NCT03145181 (phase I, 09 May 2017); NCT04557098 (phase II, 21 September 2020).

RESUMO

During breast cancer development, programmed cell death 1 ligand 1 (PD-L1) overexpression in neutrophils leads to delayed apoptosis and promotes neutrophil hyperproliferation in the lung to form a premetastatic niche, which is beneficial for pulmonary metastasis. Platycodin D (PlaD), a triterpenoid saponin with known anti-inflammatory and antitumor effects, has been reported to downregulate PD-L1 expression. This study aimed to investigate the inhibitory effect of PlaD on neutrophil PD-L1 in 4 T1 tumor-bearing mice and the potential mechanism of breast cancer pulmonary metastasis. In this study, the orthotopic 4 T1 murine mammary carcinoma model was administered 10 and 20 mg/kg PlaD by gavage. PlaD reduced the excess neutrophils and decreased their high migratory capacity in bone marrow, peripheral blood and lung tissue in the premetastatic period, thereby effectively inhibiting tumor growth and pulmonary metastasis. Moreover, PlaD inhibited the phosphatidylinositol-3-kinase (PI3K)/Akt pathway by decreasing the expression of PD-L1 in neutrophils and promoted neutrophil apoptosis. In vitro, PlaD treatment decreased the viability and inhibited migration of neutrophil-like dHL-60 in a dose-dependent manner. Similarly, PlaD inhibited the increase in PD-L1 induced by IFN-γ stimulation and subsequently induced apoptosis in dHL-60 cells. In conclusion, the administration of PlaD inhibited the PI3K/Akt signaling pathway by reducing the expression of PD-L1 in neutrophils. PlaD promoted neutrophil apoptosis, thereby inhibiting the establishment of a premetastatic niche and ultimately blocking the development of pulmonary metastasis.

RESUMO

WHAT IS THIS SUMMARY ABOUT?: This is a summary of a phase 1-2 clinical trial called MajesTEC-1. This trial tested the cancer drug teclistamab in people with relapsed or refractory multiple myeloma, a cancer that forms in a certain type of white blood cells known as plasma cells. Most participants who took part in the study had at least 3 prior treatments for multiple myeloma before their cancer came back. HOW WAS THE STUDY IN THIS SUMMARY CONDUCTED?: A total of 165 participants from 9 countries were included in this study. All participants were given teclistamab once per week and monitored for side effects. Once participants started taking teclistamab, they were checked regularly to monitor if their cancer had no change, improved (responded to treatment), or worsened or spread (known as disease progression). WHAT WERE THE RESULTS OF THE STUDY?: After approximately 14.1 months of follow-up (from 2020 to 2021), 63% of participants who were given teclistamab had a decrease in myeloma burden, meaning that they responded to treatment with teclistamab. Participants who responded to teclistamab lived without their myeloma coming back for approximately 18.4 months. The most common side effects were infections, cytokine release syndrome, abnormally low white and red blood cell counts (neutropenia, lymphopenia, and anemia), and low platelet cell counts (thrombocytopenia). Approximately 65% of participants experienced serious side effects. WHAT DO THE RESULTS OF THIS STUDY MEAN?: Overall, more than half of the participants (63%) in the MajesTEC-1 study responded to treatment with teclistamab despite previous myeloma treatment failures. Clinical Trial Registration: NCT03145181, NCT04557098 (ClinicalTrials.gov).

RESUMO

Aim: We compared the effectiveness of teclistamab versus real-world physician's choice of therapy (RWPC) in triple-class exposed relapsed/refractory multiple myeloma. Materials & methods: MajesTEC-1 eligibility criteria were applied to the RWPC cohort. Baseline covariate imbalances were adjusted using inverse probability of treatment weighting. Overall survival, progression-free survival and time to next treatment were compared. Results: After inverse probability of treatment weighting, baseline characteristics were similar between cohorts (teclistamab, n = 165; RWPC, n = 364 [766 observations]). Teclistamab treated patients had numerically better overall survival (hazard ratio [HR]: 0.82 [95% CI: 0.59-1.14]; p = 0.233) and significantly greater progression-free survival (HR: 0.43 [0.33-0.56]; p < 0.0001) and time to next treatment (HR: 0.36 [0.27-0.49]; p < 0.0001) versus the RWPC cohort. Conclusion: Teclistamab offered clinical benefit over RWPC in triple-class exposed relapsed/refractory multiple myeloma.

RESUMO

Similar to blood, interstitial fluid (ISF) contains exogenous drugs and biomarkers and may therefore substitute blood in drug analysis. However, current ISF extraction techniques require bulky instruments and are both time-consuming and complicated, which has inspired the development of viable alternatives such as those relying on skin or tissue puncturing with microneedles. Currently, microneedles are widely employed for transdermal drug delivery and have been successfully used for ISF extraction by different mechanisms to facilitate subsequent analysis. The integration of microneedles with sensors enables in situ ISF analysis and specific compound monitoring, while the integration of monitoring and delivery functions in wearable devices allows real-time dose modification. Herein, we review the progress in drug analysis based on microneedle-assisted ISF extraction and discuss the related future opportunities and challenges.

RESUMO

Polyethylene-b-polypeptide copolymers are biologically interesting, but studies of their synthesis and properties are very few. This paper reports synthesis and characterization of well-defined amphiphilic polyethylene-block-poly(L-lysine) (PE-b-PLL) block copolymers by combining nickel-catalyzed living ethylene polymerization with controlled ring-opening polymerization (ROP) of ε-benzyloxycarbonyl-L-lysine-N-carboxyanhydride (Z-Lys-NCA) and sequential post-functionalization. Amphiphilic PE-b-PLL block copolymers self-assembled into spherical micelles with a hydrophobic PE core in aqueous solution. The pH and ionic responsivities of PE-b-PLL polymeric micelles were investigated by means of fluorescence spectroscopy, dynamic light scattering, UV-circular dichroism, and transmission electron microscopy. The variation of pH values led to the conformational alteration of PLL from α-helix to coil, thereby changing the micelle dimensions.

RESUMO

BACKGROUND: Teclistamab, a B-cell maturation antigen × CD3 bispecific antibody, demonstrated an overall response rate of 63.0% in 165 heavily pretreated patients with relapsed or refractory multiple myeloma in the phase 1/2 MajesTEC-1 study. Cytokine release syndrome (CRS), a known manifestation of T-cell redirection, was observed in 119 of 165 patients (72.1%). METHODS: Patients received once-weekly teclistamab 1.5 mg/kg subcutaneously after two step-up doses (0.06 and 0.3 mg/kg). CRS was graded according to American Society for Transplantation and Cellular Therapy criteria and managed according to the study protocol, including use of tocilizumab and/or steroids. RESULTS: Most cases of CRS occurred during the step-up dosing schedule of teclistamab and were grade 1 (50.3% of patients) or grade 2 (21.2% of patients); a single case of grade 3 CRS was reported in a patient with concurrent grade 3 pneumonia. All CRS cases resolved and none led to treatment discontinuation. Overall, 33.3% of patients had >1 CRS event; CRS recurrence was reduced when tocilizumab was administered for the first CRS event compared with when it was not (20.0% vs. 62.2%, respectively). Baseline characteristics such as tumor burden and cytokine levels did not appear to predict CRS incidence or severity. CONCLUSIONS: Findings of this study support the need for preemptive planning and prompt management of CRS in patients treated with T-cell-engaging bispecific antibodies. Intervention with tocilizumab for CRS appears to decrease the likelihood of patients experiencing subsequent CRS events without compromising response to teclistamab. PLAIN LANGUAGE SUMMARY: Cytokine release syndrome (CRS), observed in 72.1% of patients treated with teclistamab in the MajesTEC-1 study, was mostly grade 1 or 2 and manageable, without requiring treatment discontinuation. Most CRS occurred during the step-up schedule, requiring vigilance during treatment initiation. Ensure fever is resolved and patients have no signs of infection before initiating the teclistamab step-up schedule or administering the next teclistamab dose, to avoid exacerbating CRS. Tocilizumab reduced the risk of subsequent CRS in patients receiving it for their first CRS event (20.0% vs. 62.2% in those not receiving it), without affecting response to teclistamab. No baseline characteristics, including tumor burden or cytokine levels, appeared to clearly predict for CRS occurrence or severity.

RESUMO

BACKGROUND: The efficacy and safety of teclistamab in patients with RRMM who received ≥3 prior lines of therapy and were triple-class exposed (TCE) are being evaluated in the single-arm, multicohort, phase I/II MajesTEC-1 trial (NCT04557098). We evaluated the comparative effectiveness of teclistamab versus physician's choice (PC) of therapy in TCE RRMM patients. METHODS: Individual patient-level data from MajesTEC-1 patients who received teclistamab (1.5 mg/kg weekly; clinical cutoff March 16, 2022) were included. An external control arm was created from patients in long-term follow-up of 4 clinical trials of daratumumab who were treated with PC therapy after discontinuation of trial treatments. In the primary analysis, inverse probability of treatment weighting was used to adjust for imbalances in 9 baseline covariates. A fully adjusted model included 5 additional prognostic factors. Outcomes included overall response rate (ORR), very good partial response or better (≥VGPR) rate, overall survival (OS), progression-free survival (PFS), and time to next treatment (TTNT). RESULTS: After adjustment, baseline characteristics were balanced between cohorts. In the primary analysis, outcomes were significantly improved with teclistamab versus PC: ORR (OR [95% CI] 4.81 [3.04-7.72]; P < .0001); ≥VGPR rate (OR, 12.07 [6.91-22.11]; P < .0001); OS (HR, 0.54 [0.40-0.73]; P < .0001); PFS (HR, 0.59 [0.46-0.78]; P = .0001); and TTNT (HR, 0.32 [0.24-0.42]; P < .0001). Results of the fully adjusted model were consistent with the primary analysis. CONCLUSION: Teclistamab showed significantly improved effectiveness versus PC on all outcomes, highlighting its clinical benefit in patients with TCE RRMM and limited treatment options.

RESUMO

The liver metastasis is the primary factor attributing to the poor prognosis of colorectal cancer (CRC). Moxibustion has been used clinically against multiple malignancies. In this study, we explored the safety, efficacy, and the potential functional mechanisms of moxibustion in modulating the liver metastasis of CRC by using GFP-HCT116 cells-derived CRC liver metastasis model in Balb/c nude mice. The tumor bearing mice were randomly divided into model control and treatment groups. Moxibustion was applied to the BL18 and ST36 acupoints. CRC liver metastasis was measured by fluorescence imaging. Furthermore, feces from all mice were collected, and 16S rRNA analysis was used to assess their microbial diversity, which was analyzed for its correlation with liver metastasis. Our results indicated that the liver metastasis rate was decreased significantly by moxibustion treatment. Moxibustion treatment also caused statistically significant changes in the gut microbe population, suggesting that moxibustion reshaped the imbalanced gut microbiota in the CRC liver metastasis mice. Therefore, our findings provide new insights into the host-microbe crosstalk during CRC liver metastasis and suggest moxibustion could inhibit CRC liver metastasis by remolding the structure of destructed gut microbiota community. Moxibustion may serve as a complementary and alternative therapy for the treatment of patients with CRC liver metastasis.

RESUMO

INTRODUCTION: Patients with triple-class-exposed relapsed/refractory multiple myeloma (TCE-RRMM) have a poor prognosis and limited treatment options. Teclistamab, a B-cell maturation antigen × CD3 bispecific antibody, was studied in patients with TCE-RRMM in the single-arm MajesTEC-1 study. To assess the relative effectiveness of teclistamab versus real-world physician's choice of therapy (RWPC), adjusted comparisons were performed using individual patient data from MajesTEC-1 and LocoMMotion, a prospective study of patients with TCE-RRMM. METHODS: An external control arm for MajesTEC-1 was created from patients in LocoMMotion (n = 248; clinical cut-off: November 2, 2021) and compared with treated patients (n = 165) from MajesTEC-1 (teclistamab 1.5 mg/kg weekly; clinical cut-off: March 16, 2022). Inverse probability weighting was used to adjust for imbalances in baseline covariates. For binary endpoints [overall response rate (ORR), very good partial response or better (≥ VGPR) rate, complete response or better (≥ CR)], relative effect of teclistamab versus RWPC was estimated with an odds ratio and relative response rate and 95% confidence interval (CI), derived from weighted logistic regression. Weighted Cox proportional hazards model was used to estimate hazard ratios (HR) and 95% CIs for time-to-event endpoints [duration of response (DOR), progression-free survival (PFS), and overall survival (OS)]. RESULTS: After weighting, baseline characteristics were balanced across cohorts. In adjusted comparisons, teclistamab-treated patients were 2.3-fold, 5.2-fold and 148.3-fold, more likely to reach ORR [response-rate ratio (RR) = 2.31, 95% CI 1.77-2.85, p < 0.0001], ≥ VGPR (RR = 5.19, 95% CI 3.26-7.12, p < 0.0001) and ≥ CR (RR = 148.25, 95% CI 20.63-1065.40, p < 0.0001), respectively, versus patients receiving RWPC. Following adjustment, DOR (HR 0.32, 95% CI 0.19-0.54, p < 0.0001) and PFS (HR 0.48, 95% CI 0.35-0.65, p < 0.0001) were significantly longer with teclistamab versus RWPC. OS was numerically better with teclistamab versus RWPC [HR 0.77 (0.55-1.09), p = 0.1419]. CONCLUSION: Teclistamab demonstrated improved effectiveness versus RWPC, highlighting its clinical benefit as a novel and effective treatment for patients with TCE-RRMM.

RESUMO

Purpose: Acupuncture has been used for almost half a century to treat and prevent cardiovascular (CV) problems. However, most of its effects are poorly understood, and there are few studies based on bibliometric analysis of the general trends in acupuncture therapy in cardiovascular disorders (CVD). Thus, we aimed to show the present state and trends in this sector during the last few years. Methods: Articles were obtained from the Web of Science Core Collection (WOSCC) from its inception to May 30, 2021. The acquired information from the articles was analyzed by The Online Bibliometric Analysis Platform website (https://bibliometric.com), Citespace and VOSviewer in respective form in order to assess and forecast the hottest areas and trends in this field. Results: The final analysis included a total of 384 articles and reviews. Over the years, the number of publications has gradually increased. The United States and University of California Irvine were the country and institution that contributed the most to the field. John C Longhurst was the most productive author; Li P the most cited author. Co-occurrence analysis revealed 5 branches (including acupuncture, blood pressure, electroacupuncture, stimulation, cardiovascular responses) and 12 clusters. Recent keyword bursts included "reflex," "arcuate nucleus," "electroacupuncture," "cardiovascular disease" and "hypertension." Conclusion: Yearly publications continue to increase every decade, indicating a bright future in this scientific field. Acupuncture's function in CVD is a future study priority.

RESUMO

OBJECTIVE: To identify topics attracting growing research attention as well as frontier trends of acupuncture-neuroimaging research over the past two decades. METHODS: This paper reviewed data in the published literature on acupuncture neuroimaging from 2000 to 2020, which was retrieved from the Web of Science database. CiteSpace was used to analyze the publication years, countries, institutions, authors, keywords, co-citation of authors, journals, and references. RESULTS: A total of 981 publications were included in the final review. The number of publications has increased in the recent 20 years accompanied by some fluctuations. Notably, the most productive country was China, while Harvard University ranked first among institutions in this field. The most productive author was Tian J with the highest number of articles (50), whereas the most co-cited author was Hui KKS (325). Evidence-Based Complementary and Alternative Medicine (92) was the most prolific journal, while Neuroimage was the most co-cited journal (538). An article written by Hui KKS (2005) exhibited the highest co-citation number (112). The keywords "acupuncture" (475) and "electroacupuncture" (0.10) had the highest frequency and centrality, respectively. Functional magnetic resonance imaging (fMRI) ranked first with the highest citation burst (6.76). CONCLUSION: The most active research topics in the field of acupuncture-neuroimaging over the past two decades included research type, acupoint specificity, neuroimaging methods, brain regions, acupuncture modality, acupoint specificity, diseases and symptoms treated, and research type. Whilst research frontier topics were "nerve regeneration", "functional connectivity", "neural regeneration", "brain network", "fMRI" and "manual acupuncture".

RESUMO

OBJECTIVE: Chemotherapy-induced peripheral neuropathy (CIPN) is a dose-limiting adverse effect of anticancer agents with virtually no effective treatment. Safe and effective therapies are needed urgently. Acupuncture shows therapeutic possibilities in this regard but needs to be further evaluated. METHODS: A systematic search was conducted in seven databases from their inception to April 2020. Randomized controlled trials (RCTs) focused on acupuncture/electroacupuncture (EA) for the treatment of CIPN were included. Revman 5.3 software was used for meta-analysis if there was no significant heterogeneity. Otherwise, qualitative analysis was utilized. RESULTS: Nine studies involving 582 patients were included in this review. Most of the studies exhibited unclear risk of bias because some details were not mentioned. As the clinical heterogeneity was significant, qualitative analysis was performed to describe nerve conduction velocity, effective rate for motor neuropathy, pain scores, quality of life and adverse events. Meta-analysis was performed on four studies to analyze the effective rate for sensory neuropathy due to inconspicuous heterogeneity. The results indicated that acupuncture may generate a better effect on sensory neuropathy than vitamin B (risk ratio = 1.60, 95% confidence interval = 1.31-1.95, I2 = 0%, p < 0.00001). The efficacy of EA plus glutathione (GSH) appeared to be better than that of GSH alone in alleviating sensory neurotoxicity and in improving nerve conduction velocity. Acupuncture plus methylcobalamin showed more favorable effects than methylcobalamin alone in relieving neuralgia, restoring nerve conduction velocity and improving quality of life. In terms of pain relief and improved CIPN-specific quality of life, acupuncture plus standard care was better than standard care alone. In terms of pain relief, EA was more effective than usual care. CONCLUSION: Acupuncture may be effective and safe in the treatment of CIPN according to the analyzed studies. However, more studies with higher methodological quality are warranted in order to be able to draw firmer conclusions. Future rigorous RCTs will be necessary to confirm the effectiveness and safety of acupuncture for CIPN.

RESUMO

Professor SUN Jian-hua proposes that the disease location of functional gastrointestinal disorders is brain, spleen and intestines; the liver-depression and spleen-deficiency is the basis of pathogenesis; the core pathogenesis is the dysfunction of qi and disability of conducting; the key to pathogenesis is the imbalance of heart, brain and mind. The "regulating-mind and strengthening-spleen" acupuncture therapy could treat functional gastrointestinal disorders. The first essence of treatment is regulating the mind, and the treatment principles are soothing the liver and strengthening the spleen, improving the mind and regulating the intestines. In addition, the moxibustion therapy and auricular points therapy are suggested to use together. Moreover, psychological counseling and health education are important, especially attention should be paid to the treatment of the mind and body, so as to synergize the treatment effect.

RESUMO

OBJECTIVE: To compare the differences in functional connectivity(FC) between the hypothalamus and whole brain regions in patients with premature ovarian insufficiency (POI) and healthy volunteers based on resting-state functional magnetic resonance imaging (rs-fMRI) and investigate the mechanism of acupuncture on treatment of POI. METHODS: Twelve POI patients were recruited to the acupuncture group and 12 healthy volunteers to the control group. Patients in the acupuncture group received acupuncture at two groups of acupoints alternatively, including Baihui (GV20), Zhongwan (CV12), Shenting (GV24), Shenshu (BL23), Ciliao(BL32) and so on, 30 min once time, 3 times per week for 12 weeks. The state of patients was evaluated by modified Kupperman Index (KI) and self-rating anxiety scale (SAS). Follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2), and anti-mullerian hormone (AMH) were tested by microparticle-based chemiluminescence. B ultrasonography was used to detect the antral follicle count (AFC). Meanwhile, POI patients and healthy volunteers underwent the rs-fMRI examination before and after acupuncture treatment and after enrollment, respectively. With hypothalamus as the region of interest, the differences in FC between the hypothalamus and other brain regions in POI patients and healthy volunteers and the changes of FC between the hypothalamus and whole brain regions in POI patients before and after acupuncture were observed. RESULTS: The SAS and KI scores of pre-treatment POI patients were higher than those in the control group (P<0.01).In compa-rison with those pre-treatment, FSH, LH, and SAS and KI scores of POI patients decreased after treatment, while AFC increased (P<0.05). Compared with the control group, the FC of the left hypothalamus with left central sulcus, right middle occipital gyrus, and left paracentral lobule increased, but decreased with left globus pallidus of the lenticular nucleus in POI patients. Furthermore, the FC of the right hypothalamus with the left hippocampus, the left para-central lobule, and the right central sulcus increased, while the FC between the right hypothalamus and the right superior frontal gyrus decreased (P<0.05). For the acupuncture group, compared with the conditions before treatment, the FC of the right hypothalamus with the left inferior frontal gyrus, the left insula, and right inferior frontal gyrus was strengthened, but weakened with the left gyrus rectus (P<0.05). CONCLUSION: The abnormal FC between the hypothalamus and whole brain regions may be one of the central pathological factors of POI. Acupuncture can improve the ovarian function and clinical symptoms of patients with POI, which may be related to its effect in regulating the FC between the hypothalamus and multiple brain regions.
