Factors associated with perceived cognitive function in breast cancer patients treated with chemotherapy: A multicenter cross-sectional study.

PURPOSE: This study aimed to investigate the factors associated with perceived cognitive function among breast cancer patients treated with chemotherapy in China. METHODS: The study was a multicenter cross-sectional design. Data were collected from 10 public hospitals in China between April 2022 and February 2023. A total of 741 participants completed questionnaires assessing sociodemographic and medical characteristics, perceived cognitive function, sleep quality, fatigue, anxiety, and depression. Hierarchical multiple regression analysis was used to assess the determinants of cognitive function. RESULTS: The hierarchical multiple regression model accounted for 31.5% of variation in perceived cognitive function (sociodemographic 4.5%; medical 6.6%; exercise frequency 6.6%; sleep quality 2.1%; fatigue 2.8%; anxiety combined with depression 9.0%). Education level, chemotherapy type, number of chemotherapy cycles, and cyclophosphamide drug use were significant predisposing factors of perceived cognitive function (p < 0.001). Exercising ≥3 times/week (p < 0.001) was a significant factor positively influencing perceived cognitive function, meanwhile, anxiety (p < 0.001) and depression (p < 0 0.001) were negative factors. CONCLUSION: Our findings suggest that patients with low education levels, postoperative chemotherapy, cyclophosphamide treatment, and a greater number of chemotherapy cycles need more assessment. Sedentary patients, those who have never exercised, and those with anxiety or depression all showed greater cognitive decline. By identifying susceptible populations, encouraging regular exercise, and addressing anxiety and depression, healthcare professionals can contribute significantly to prevent patients' cognitive decline throughout chemotherapy.

[Application of femoral I.D.E.A.L localization in anterior cruciate ligament reconstruction with single bundle anterior cruciate ligament].

OBJECTIVE: To evaluate the effect of femoral I.D.E.A.L localization in single bundle anterior cruciate ligament reconstruction (ACLR). METHODS: From January 2019 to October 2022, 122 patients with anterior cruciate ligament injury were treated with ACLR, including 83 males and 39 females. The age ranged from 23 to 43 years old, with an average of (32.19 ±8.55) years old. The course of disease ranged from 1 week to 6 months. According to the different surgical schemes, the patients were divided into two groups, namely the traditional group, which adopted the over-the-top femoral lateral positioning scheme, including 64 patients. The I.D.E.A.L group adopted the I.D.E.A.L femoral lateral positioning scheme, including 58 patients. The patient has pain and dysfunction of knee joint before operation. MRI of knee joint indicates anterior cruciate ligament injury. The visual analogue scale(VAS), International Knee Documentation Committee(IKDC) scoring system and Lysholm scoring system were used to evaluate the knee joint function of the patient. KT-2000 was used to detect the recovery of knee joint after operation and to count the postoperative complications. RESULTS: The wounds healed well after operation. One hundred and twenty-tow patients were followed up for 15 to 46 months, with an average of (25.45±9.22) months. The knee joint stability of patients after operation was significantly increased. The VAS at 1 day and 1 week after operation of patients in the I.D.E.A.L group was significantly lower than that in the traditional group(P<0.05). The IKDC score and Lysholm score of patients in the I.D.E.A.L group were significantly higher than those in the traditional group(P<0.05). In the traditional group, there were 6 cases of short-term (<1 month) complications and 19 cases of long-term (≥1 month)complicatios. In the I.D.E.A.L group, there were 3 cases of short-term complications and 7cases of long-term complications(P<0.05). CONCLUSION: The single bundle anterior cruciate ligament reconstruction and femoral I.D.E.A.L positioning can achieve better early postoperative effect and reduce early postoperative pain.

The Elk-3 target Abhd10 ameliorates hepatotoxic injury and fibrosis in alcoholic liver disease.

Alcoholic liver disease (ALD) and other forms of chronic hepatotoxic injury can lead to transforming growth factor ß1 (TGFß1)-induced hepatic fibrosis and compromised liver function, underscoring the need to develop novel treatments for these conditions. Herein, our analyses of liver tissue samples from severe alcoholic hepatitis (SAH) patients and two murine models of ALD reveals that the ALD phenotype was associated with upregulation of the transcription factor ETS domain-containing protein (ELK-3) and ELK-3 signaling activity coupled with downregulation of α/ß hydrolase domain containing 10 (ABHD10) and upregulation of deactivating S-palmitoylation of the antioxidant protein Peroxiredoxin 5 (PRDX5). In vitro, we further demonstrate that ELK-3 can directly bind to the ABHD10 promoter to inhibit its transactivation. TGFß1 and epidermal growth factor (EGF) signaling induce ABHD10 downregulation and PRDX5 S-palmitoylation via ELK-3. This ELK-3-mediated ABHD10 downregulation drives oxidative stress and disrupts mature hepatocyte function via enhancing S-palmitoylation of PRDX5's Cys100 residue. In vivo, ectopic Abhd10 overexpression ameliorates liver damage in ALD model mice. Overall, these data suggest that the therapeutic targeting of the ABHD10-PRDX5 axis may represent a viable approach to treating ALD and other forms of hepatotoxicity.

Air pollution and infant mortality: Evidence from China.

Using a newly assembled prefecture-city level dataset from 2004 to 2015, this paper examines the impact of air pollution on child mortality in China. To identify the causal effect, we exploit ventilation coefficient as the instrument for urban air pollution. We find that a 10 µg/m3 increase in annual PM2.5 concentration causes 163 infant deaths per 100,000 live births per year in a city.

Effects of multidisciplinary exercise management on patients after percutaneous coronary intervention: A randomized controlled study.

Objectives: To explore the effectiveness of the mobile app-based multidisciplinary exercise management on patients who receive percutaneous coronary intervention (PCI). Methods: From January to October 2020, 54 patients after PCI were randomly assigned to the intervention group (n = 27) and the control group (n = 27). The intervention group received the mobile app-based multidisciplinary exercise management, whereas the control group received routine care. The patients after PCI began to take intervention one month after the operation, and the intervention lasted for two months. Before and after the intervention, 6-Minute Walking Distance was used to evaluate the patient's exercise tolerance, and the patient's exercise compliance was evaluated according to the patient's exercise status recorded by the mobile app. The cognitive questionnaire on knowledge about PCI treatment for Coronary Heart Disease, the Self-efficacy for Chronic Disease Scale and the Perceived Social Support Scale were used to evaluate patients' disease-related cognition, self-efficacy and perception of social support. This study was registered on Clinical Trials.gov with registration number ChiCTR2000028930. Results: Totally 51 patients after PCI who completed this study (25 patients in the intervention group and 26 patients in the control group) were included in the analysis. After 2 months of intervention, the exercise compliance of patients in the intervention group was better than that in the control group. And 6-Minute Walking Distance (469.36 ± 57.48 vs. 432.81 ± 67.09), and the scores of knowledge of PCI treatment for coronary heart disease (52.64 ± 9.82 vs. 42.42 ± 8.54), Self-efficacy for Chronic Disease Scale (42.40 ± 8.04 vs. 36.88 ± 7.73) and Perceived Social Support Scale (74.04 ± 5.73 vs. 66.69 ± 6.86) in the intervention group were higher than those in the control group with statistical significance (P < 0.05). Conclusions: The multidisciplinary exercise management based on the mobile app can effectively improve exercise tolerance, exercise compliance, disease-related cognition, self-efficacy, and perception of social support during exercise training for patients after PCI.

Computational identification of new potential transcriptional partners of ERRα in breast cancer cells: specific partners for specific targets.

Estrogen related receptors are orphan members of the nuclear receptor superfamily acting as transcription factors (TFs). In contrast to classical nuclear receptors, the activities of the ERRs are not controlled by a natural ligand. Regulation of their activities thus relies on availability of transcriptional co-regulators. In this paper, we focus on ERRα, whose involvement in cancer progression has been broadly demonstrated. We propose a new approach to identify potential co-activators, starting from previously identified ERRα-activated genes in a breast cancer (BC) cell line. Considering mRNA gene expression from two sets of human BC cells as major endpoint, we used sparse partial least squares modeling to uncover new transcriptional regulators associated with ERRα. Among them, DDX21, MYBBP1A, NFKB1, and SETD7 are functionally relevant in MDA-MB-231 cells, specifically activating the expression of subsets of ERRα-activated genes. We studied SET7 in more details and showed its co-localization with ERRα and its ERRα-dependent transcriptional and phenotypic effects. Our results thus demonstrate the ability of a modeling approach to identify new transcriptional partners from gene expression. Finally, experimental results show that ERRα cooperates with distinct co-regulators to control the expression of distinct sets of target genes, thus reinforcing the combinatorial specificity of transcription.

Family care and subjective well-being of coronary heart disease patients after percutaneous coronary intervention: Mediating effects of coping strategies.

OBJECTIVES: To analyze the correlations between family care, coping strategies and the subject well-being (SWB) of patients with coronary heart disease (CHD) after percutaneous coronary intervention (PCI). METHODS: From November 2019 to October 2020, 264 CHD patients who had undergone PCI were enrolled in this questionnaire survey. The research tools applied included General Information Questionnaire, the Adaptation, Partnership, Growth, Affection and Resolve, Medical Coping Modes Questionnaire, and the General Well-being Schedule. SPSS 24.0 and Amos 23.0 software packages were used for statistical analysis. RESULTS: The mean scores for family care, confrontation, avoidance, acceptance-resignation and SWB, were 7.59 ± 2.24, 20.03 ± 3.78, 16.49 ± 2.70, 10.42 ± 2.01, and 73.31 ± 11.63, respectively. Subgroup analysis showed that the path coefficient between family care and subjective well-being was higher in males than females. Family care was directly related to coping strategies. The coping strategies were directly related to SWB, while family care showed an indirect association with SWB via coping strategies. CONCLUSIONS: Family care can improve CHD patients' SWB post-PCI, and coping strategies are important for the link between family care and SWB. Also, men received more family care than women. Based on a patient's characteristics, healthcare providers can promote patients' positive coping strategies, increase their perceived family care, and improve the patient's SWB.

Supportive Care Needs of Chinese Women With Newly Diagnosed Breast Cancer Prior to Adjuvant Chemotherapy.

PURPOSE: To describe the supportive care needs of Chinese women newly diagnosed with breast cancer prior to adjuvant chemotherapy. PARTICIPANTS & SETTING: 13 women newly diagnosed with breast cancer were recruited from a public teaching hospital in northern China. METHODOLOGIC APPROACH: Semistructured interviews were conducted, and data were analyzed following a qualitative descriptive approach and qualitative content analysis. FINDINGS: The following five themes emerged. IMPLICATIONS FOR NURSING: Nurses should focus on patients' prechemotherapy supportive care needs and comprehensively assess their specific needs and concerns related to post-surgery discomfort and chemotherapy, with considerations of the Chinese family concept, diet, and traditional culture. Targeted health information and psychological support are necessary to help patients transition to and adequately prepare for chemotherapy.

The Pah-R261Q mouse reveals oxidative stress associated with amyloid-like hepatic aggregation of mutant phenylalanine hydroxylase.

Phenylketonuria (PKU) is caused by autosomal recessive variants in phenylalanine hydroxylase (PAH), leading to systemic accumulation of L-phenylalanine (L-Phe) that may reach neurotoxic levels. A homozygous Pah-R261Q mouse, with a highly prevalent misfolding variant in humans, reveals the expected hepatic PAH activity decrease, systemic L-Phe increase, L-tyrosine and L-tryptophan decrease, and tetrahydrobiopterin-responsive hyperphenylalaninemia. Pah-R261Q mice also present unexpected traits, including altered lipid metabolism, reduction of liver tetrahydrobiopterin content, and a metabolic profile indicative of oxidative stress. Pah-R261Q hepatic tissue exhibits large ubiquitin-positive, amyloid-like oligomeric aggregates of mutant PAH that colocalize with selective autophagy markers. Together, these findings reveal that PKU, customarily considered a loss-of-function disorder, can also have toxic gain-of-function contribution from protein misfolding and aggregation. The proteostasis defect and concomitant oxidative stress may explain the prevalence of comorbid conditions in adult PKU patients, placing this mouse model in an advantageous position for the discovery of mutation-specific biomarkers and therapies.

The effectiveness of diaphragmatic breathing relaxation training for improving sleep quality among nursing staff during the COVID-19 outbreak: a before and after study.

OBJECTIVES: Recent studies have demonstrated that first-line nurses involved in the coronavirus disease-2019 (COVID-19) crisis may experience sleep disturbances. As breathing relaxation techniques can improve sleep quality, anxiety, and depression, the current study aimed to evaluate the effectiveness of diaphragmatic breathing relaxation training (DBRT) for improving sleep quality among nurses in Wuhan, China during the COVID-19 outbreak. METHODS: This study used a quasi-experimental (before and after) intervention strategy, with 151 first-line nurses from four wards in Leishenshan hospital. The Pittsburgh Sleep Quality Index (PSQI), Self-Rating Anxiety Scale (SAS), and Self-Rating Depression Scale (SDS) to evaluate the effectiveness of DBRT before and after the intervention. Data were examined using the Shapiro-Wilk test, Levene's test, and paired t-test. RESULTS: A total of 140 nurses completed the DBRT sessions. First-line nurses achieved significant reductions in global sleep quality (p < 0.01), subjective sleep quality (p < 0.001), sleep latency (p < 0.01), sleep duration (p < 0.001), sleep disturbances (p < 0.001), habitual sleep efficiency (p = 0.015), daytime dysfunction (p = 0.001), and anxiety (p = 0.001). There were no significant reductions in the use of sleeping medication (p = 0.134) and depression (p = 0.359). CONCLUSION: DBRT is a useful non-pharmacological treatment for improving sleep quality and reducing anxiety among first-line nurses involved in the COVID-19 outbreak. The study protocol was clinically registered by the Chinese Clinical Trial Registry. CLINICAL TRIAL REGISTRATION NUMBER: ChiCTR2000032743.

Long non-coding RNA LINC00460 promotes proliferation and inhibits apoptosis of cervical cancer cells by targeting microRNA-503-5p.

Long non-coding RNAs are associated with the pathogenesis of cancers. Moreover, LINC00460 is involved in the development of multiple cancers. However, the function of LINC00460 in cervical cancer (CC) remains inconclusive. Herein, CC tissues and tumor-adjacent tissues were collected from patients. The effect of LINC00460 silencing in cell proliferation and apoptosis in CC was explored in vitro and in vivo. Additionally, the interaction between LINC00460 and miR-503-5p was analyzed using dual luciferase reporter assay. The expression of genes and proteins was assayed using quantitative real-time PCR, western blotting and immunohistochemistry, cell viability using MTT assay, cell cycle distribution using flow cytometry, cell apoptosis using Annexin V staining, Hoechst staining and TUNEL assay. LINC00460 levels in CC tissues were higher than tumor-adjacent tissues. LINC00460 silencing suppressed proliferation and promoted apoptosis of CC cells as evidenced by decreased cell viability, inhibited proliferation-related protein and cell cycle protein expressions and G1/S transition, increased apoptotic cells and Hoechst-positive cells, and enhanced apoptosis-related protein expressions. LINC00460 could bind to miR-503-5p and LINC00460 silencing enhanced miR-503-5p expression and inhibited its target gene expressions in CC cells. MiR-503-5p inhibition reversed LINC00460 silencing-caused inhibition of cell proliferation and miR-503-5p target gene expressions, and promotion of cell apoptosis. LINC00460 silencing also attenuated tumor growth, promoted miR-503-5p levels and cell apoptosis, and inhibited cell proliferation and miR-503-5p target gene expressions in tumor tissues. Hence, LINC00460 functioned as an oncogene in CC that affected cell proliferation and apoptosis via sponging miR-503-5p. This study provides a novel therapeutic target for CC.

The Relationship Among Rumination, Coping Strategies, and Subjective Well-being in Chinese Patients With Breast Cancer: A Cross-sectional study.

PURPOSE: To investigate the relationship between rumination, coping strategies, and subjective well-being (SWB) and test the mediating effects of coping strategies on rumination and SWB in patients with breast cancer (BC). METHODS: This cross-sectional study assessed rumination, coping strategies, and SWB using the General Well-being Schedule, the Chinese Event-Related Rumination Inventory, and the Medical Coping Modes Questionnaire in BC patients admitted to a tertiary general hospital in China. RESULTS: SWB was positively associated with the total score for rumination (r = .32, p < .01), deliberate rumination (r = .75, p < .01), and confrontation (r = .58, p < .01). The relationship between rumination and SWB was mediated by confrontation (indirect effect = .74). CONCLUSION: BC diagnosis can affect patient's SWB. These findings indicate that rumination and confrontation have direct and indirect effects on SWB. Therefore, psychological interventions focused on improving coping may increase SWB. Notwithstanding, larger longitudinal studies are needed to further examine the relationship between cognitive processes, coping strategies, and SWB.

Interventions to reduce burnout of physicians and nurses: An overview of systematic reviews and meta-analyses.

OBJECTIVE: Numerous systematic reviews and meta-analyses on the interventions to reduce burnout of physicians and nurses have been published nowadays. This study aimed to summarize the evidence and clarify a bundled strategy to reduce burnout of physicians and nurses. METHODS: Researches have been conducted within Cochrane Library, PubMed, Ovid, Scopus, EBSCO, and CINAHL published from inception to 2019. In addition, a manual search for relevant articles was also conducted using Google Scholar and ancestral searches through the reference lists from articles included in the final review. Two reviewers independently selected and assessed, and any disagreements were resolved through a larger team discussion. A data extraction spreadsheet was developed and initially piloted in 3 randomly selected studies. Data from each study were extracted independently using a pre-standardized data abstraction form. The the Risk of Bias in Systematic reviews and assessment of multiple systematic reviews (AMSTAR) 2 tool were used to evaluate risk of bias and quality of included articles. RESULTS: A total of 22 studies published from 2014 to 2019 were eligible for analysis. Previous studies have examined burnout among physicians (n = 9), nurses (n = 6) and healthcare providers (n = 7). The MBI was used by majority of studies to assess burnout. The included studies evaluated a wide range of interventions, individual-focused (emotion regulation, self-care workshop, yoga, massage, mindfulness, meditation, stress management skills and communication skills training), structural or organizational (workload or schedule-rotation, stress management training program, group face-to-face delivery, teamwork/transitions, Balint training, debriefing sessions and a focus group) and combine interventions (snoezelen, stress management and resiliency training, stress management workshop and improving interaction with colleagues through personal training). Based on the Risk of Bias in Systematic reviews and AMSTAR 2 criteria, the risk of bias and methodological quality included studies was from moderate to high. CONCLUSIONS: Burnout is a complicated problem and should be dealt with by using bundled strategy. The existing overview clarified evidence to reduce burnout of physicians and nurses, which provided a basis for health policy makers or clinical managers to design simple and feasible strategies to reduce the burnout of physicians and nurses, and to ensure clinical safety.

G Protein-Gated Inwardly Rectifying Potassium Channel Subunit 3 is Upregulated in Rat DRGs and Spinal Cord After Peripheral Nerve Injury.

BACKGROUND: G protein-gated inwardly rectifying potassium (GIRK) channels are involved in the regulation of neuronal excitability. Four GIRK subunits (GIRK1-4) are expressed in rat dorsal root ganglia (DRGs). Recently, we have characterized the expression of GIRK1 and -2, and both are downregulated in rat DRGs and spinal cord after a complete sciatic nerve transection (axotomy). Here, we aimed to study the neurochemical characteristics of GIRK3, and its regulation in rat DRGs and spinal cord induced by nerve injury. METHODS: A sciatic nerve axotomy was performed to study the influences of injury on GIRK3 expression in DRGs and spinal cord. A dorsal root rhizotomy and a sciatic nerve crush were employed to study the axonal transport of GIRK3 protein, respectively. Immunohistochemistry analysis was employed for investigating the neurochemical characteristics of GIRK3. RESULTS: In control DRGs, ~18% of neuron profiles (NPs) were GIRK3-positive (+), and ~41%, ~48% and ~45% of GIRK3+ NPs were CGRP+, IB4+ and NF200+, respectively. GIRK3-like immunoreactivity was observed in glabrous skin of hind paws and axons originating from DRG neurons. Fourteen days after axotomy, more than one-third of DRG NPs were GIRK3+, and among these ~51% and ~56% coexpressed galanin and neuropeptide Y, respectively. In control animals, a small group of interneurons found in the dorsal horn was GIRK3+. In addition, GIRK3+ processes could be observed in superficial laminae of spinal dorsal horn. After nerve injury, the intensity of GIRK3-like immunoreactivity in the superficial layers was increased. Evidence based on rhizotomy and sciatic nerve crush indicated both anterograde and retrograde transport of GIRK3. CONCLUSION: Our study demonstrates that GIRK3 is expressed in sensory neurons and spinal cord. GIRK3 has both anterograde and retrograde axonal transport. GIRK3 expression can be regulated by peripheral nerve injury.

Down-regulation of lncRNA BLACAT1 inhibits ovarian cancer progression by suppressing the Wnt/ß-catenin signaling pathway via regulating miR-519d-3p.

Ovarian cancer has the highest mortality in gynecologic malignancies. LncRNA BLACAT1 serves crucial functions in various cancers, but its role in ovarian cancer has not been investigated. In this article, our team explored the role and the potential regulatory mechanism of BLACAT1 in ovarian cancer. Quantitative RT-PCR showed that BLACAT1 was aberrantly up-regulated in ovarian cancer tissues compared with normal tissues. In vitro, BLACAT1 knockdown induced cell cycle arrest and inhibited the proliferation, migration and invasion of ovarian cancer cells using flow cytometry, MTT and EdU assays, wound healing assay and transwell assay, respectively. Luciferase assay verified the binding relationship between microRNA-519d-3p and lncRNA BLACAT1, and BLACAT1 negatively regulated the expression of miR-519d-3p. We also found that miR-519d-3p overexpression could inhibit ovarian cancer cells proliferation, migration and invasion. Further, Western blot demonstrated that the expression of RPS15A and nuclear ß-catenin expression was markedly reduced by BLACAT1 knockdown, and cytoplasmic ß-catenin level was not obviously affected. In vivo, BLACAT1 knockdown inhibited the tumor growth, and immunohistochemistry showed that ki67 expression was decreased by BLACAT1 suppression. Inhibition of BLACAT1 was sufficient to down-regulate the expression of RPS15A and nuclear ß-catenin but did not cause an obvious change in cytoplasmic ß-catenin expression. Taken together, BLACAT1 knockdown inhibited the progression of ovarian cancer by suppressing the Wnt/ß-catenin signaling pathway via regulating miR-519d-3p. Our work provided a proper understanding of the critical roles of BLACAT1 in ovarian cancer.

Expression and regulation of FRMD6 in mouse DRG neurons and spinal cord after nerve injury.

FRMD6, a member of the group of FERM-domain proteins, is involved both in communication between cells, interactions with extracellular matrix, cellular apoptotic and regenerative mechanisms. FRMD6 was first discovered in the rodent sciatic nerve, and in the present immunohistochemical study we investigated the distribution of FRMD6 in the dorsal root ganglia (DRGs), sciatic nerve and spinal cord following sciatic nerve injury. FRMD6-immunoreactivity was found in the cytoplasm, nucleus or both, and in a majority of DRG neurons. FRMD6-immunoreactivity co-existed with several well-known neuronal markers, including calcitonin gene-related peptide, isolectin B4 and neurofilament 200 in mouse DRGs. After peripheral nerve injury, the FRMD6 mRNA levels and the overall percentage of FRMD6-positive neuron profiles (NPs) were decreased in ipsilateral lumbar DRGs, the latter mainly affecting small size neurons with cytoplasmic localization. Conversely, the proportion of NPs with nuclear FRMD6-immunoreactivity was significantly increased. In the sciatic nerve, FRMD6-immunoreactivity was observed in non-neuronal cells and in axons, and accumulated proximally to a ligation of the nerve. In the spinal cord FRMD6-immunoreactivity was detected in neurons in both dorsal and ventral horns, and was upregulated in ipsilateral dorsal horn after peripheral nerve axotomy. Our results demonstrate that FRMD6 is strictly regulated by peripheral nerve injury at the spinal level.

IL-10 secreting B cells regulate periodontal immune response during periodontitis.

Periodontitis is a disease caused by periodontopathogens and is characterized by periodontal inflammation and alveolar bone resorption. As has been proven, host immune responses incite the development and progression of periodontitis. The present study sought to establish B10 cell functions and mechanisms in regulating host immunity during periodontitis. Periodontopathogen-specific B10 cells were purified and then injected into recipients to create the adoptive transfer models. We compared inflammatory cytokines and regulatory T (Treg)/Th17 cell expression in a healthy, normal model, an experimental periodontitis model, and experimental periodontitis model adoptively transferred with B10 cells. Compared with experimental periodontitis animals, our results showed that transfer of B10 cells alleviated alveolar bone resorption (P < 0.05) by reducing periodontal osteoclastogenesis (P < 0.05). Additionally, we found that B10 cell transfer into the experimental periodontitis ones resulted in increased IL-10 (P < 0.05), but decreased IL-17 (P < 0.05) and receptor activator for nuclear factor κB ligand (RANKL) (P < 0.05) gene and protein expression in local lesions. Moreover, adoptive transfer of B10 cells reduced the proportion of Th17 cells (P < 0.05) in the gingiva. The results of our study confirmed that B10 cells can modulate local host immune responses and prevent inflammatory damage of alveolar bone by reducing pro-inflammatory cytokine expression and decreasing local proliferation of Th17 cells.
