Clinical Efficacy of Yiqi Yangyin Decoction Combined with Adjuvant Chemotherapy on the Postoperative Life Quality of Breast Cancer.

Postoperative adjuvant chemotherapy could improve the life quality of patients with breast cancer but also bring side effects and cause adverse reactions. Yiqi Yangyin decoction has been reported to possess anti-cancer activity and has been employed in the postoperative treatment of various cancers. A total of 128 patients with breast cancer who received surgical therapy were enrolled in this study and were randomly grouped as the control and the test group to receive different therapies. Patients in the control group received single chemotherapy of fluorouracil and hydrochloride, while the therapy of the test group patients supplemented Yiqi Yangyin decoction based on the control group. Both two therapeutic strategies improved life quality and TCM syndrome scores of enrolled patients, and the supplement of Yiqi Yangyin decoction significantly improved the therapeutic effect. Adverse reactions including nausea, vomiting, thrombocytopenia, diarrhea, leukopenia, and hemoglobinia occurred in both two groups, but the application of Yiqi Yangyin decoction significantly alleviated adverse reactions. Additionally, patients in the test group showed a better 1-year disease-free survival. The combination of adjuvant chemotherapy with Yiqi Yangyin decoction could improve postoperative life quality, improve therapeutic efficacy, and reduce adverse reactions in patients with breast cancer.

Impact of immune checkpoint molecules on FoxP3+ Treg cells and related cytokines in patients with acute and chronic brucellosis.

BACKGROUND: The immunoregulatory functions of regulatory T cells (Tregs) in the development and progression of some chronic infectious diseases are mediated by immune checkpoint molecules and immunosuppressive cytokines. However, little is known about the immunosuppressive functions of Tregs in human brucellosis, which is a major burden in low-income countries. In this study, expressions of immune checkpoint molecules and Treg-related cytokines in patients with acute and chronic Brucella infection were evaluated to explore their impact at different stages of infection. METHODS: Forty patients with acute brucellosis and 19 patients with chronic brucellosis admitted to the Third People's Hospital of Linfen in Shanxi Province between August 2016 and November 2017 were enrolled. Serum and peripheral blood mononuclear cells were isolated from patients before antibiotic treatment and from 30 healthy subjects. The frequency of Tregs (CD4+ CD25+ FoxP3+ T cells) and expression of CTLA-4, GITR, and PD-1 on Treg cells were detected by flow cytometry. Levels of Treg-related cytokines, including IL-35, TGF-ß1, and IL-10, were measured by customised multiplex cytokine assays using the Luminex platform. RESULTS: The frequency of Tregs was higher in chronic patients than in healthy controls (P = 0.026) and acute patients (P = 0.042); The frequency of CTLA-4+ Tregs in chronic patients was significantly higher than that in healthy controls (P = 0.011). The frequencies of GITR+ and PD-1+ Tregs were significantly higher in acute and chronic patients than in healthy controls (P < 0.05), with no significant difference between the acute and chronic groups (all P > 0.05). Serum TGF-ß1 levels were higher in chronic patients (P = 0.029) and serum IL-10 levels were higher in acute patients (P = 0.033) than in healthy controls. We detected weak correlations between serum TGF-ß1 levels and the frequencies of Tregs (R = 0.309, P = 0.031) and CTLA-4+ Tregs (R = 0.302, P = 0.035). CONCLUSIONS: Treg cell immunity is involved in the chronicity of Brucella infection and indicates the implication of Tregs in the prognosis of brucellosis. CTLA-4 and TGF-ß1 may contribute to Tregs-mediated immunosuppression in the chronic infection stage of a Brucella infection.

Outcomes of icotinib combined with concurrent chemoradiotherapy in locally advanced cervical cancer.

Concurrent chemoradiotherapy (CRT) based on cisplatin is recognized as the current standard treatment for locally advanced cervical cancer. The treatment of cervical cancer has reached a plateau in the last 20 years. Previous studies have proven that the epidermal growth factor receptor is correlated with chemo- and radioresistance and treatment failure. Hence, the purpose of this study was to investigate the efficacy and safety of icotinib combined with CRT in the treatment of locally advanced cervical cancer. Eligibility criteria included patients treated in the radiotherapy department of Taizhou Central Hospital of Zhejiang Province for stage IIB to IIIB cervical cancers who had not received anti-tumor treatment before and a performance status of 0 to 2. Patients were given icotinib 125 mg three times a day for 6 weeks, which was one week before the start of radiotherapy (500 centigrays in 28 fractions) and chemotherapy (40 mg/m2 administered weekly for 3-5 cycles). There were 29 patients who completed the I+CRT treatment, and it was tolerated well. The median follow-up time was 50 months and 27 patients (93.10%) achieved complete responses. The 5-year cumulative overall survival rate and disease-free survival rate were 58.4% and 60.9%, respectively. The treatment with I+CRT is safe and effective for locally advanced cervical cancer. As far as we know, this is the first study to report the 5-year survival rate of locally advanced cervical cancer with targeted therapy combined with chemoradiotherapy.

Single-cell landscape revealed immune characteristics associated with disease phases in brucellosis patients.

A comprehensive immune landscape for Brucella infection is crucial for developing new treatments for brucellosis. Here, we utilized single-cell RNA sequencing (scRNA-seq) of 290,369 cells from 35 individuals, including 29 brucellosis patients from acute (n = 10), sub-acute (n = 9), and chronic (n = 10) phases as well as six healthy donors. Enzyme-linked immunosorbent assays were applied for validation within this cohort. Brucella infection caused a significant change in the composition of peripheral immune cells and inflammation was a key feature of brucellosis. Acute patients are characterized by potential cytokine storms resulting from systemic upregulation of S100A8/A9, primarily due to classical monocytes. Cytokine storm may be mediated by activating S100A8/A9-TLR4-MyD88 signaling pathway. Moreover, monocytic myeloid-derived suppressor cells were the probable contributors to immune paralysis in acute patients. Chronic patients are characterized by a dysregulated Th1 response, marked by reduced expression of IFN-γ and Th1 signatures as well as a high exhausted state. Additionally, Brucella infection can suppress apoptosis in myeloid cells (e.g., mDCs, classical monocytes), inhibit antigen presentation in professional antigen-presenting cells (APCs; e.g., mDC) and nonprofessional APCs (e.g., monocytes), and induce exhaustion in CD8+ T/NK cells, potentially resulting in the establishment of chronic infection. Overall, our study systemically deciphered the coordinated immune responses of Brucella at different phases of the infection, which facilitated a full understanding of the immunopathogenesis of brucellosis and may aid the development of new effective therapeutic strategies, especially for those with chronic infection.

DUSP1 Signaling Pathway Regulates Cytarabine Sensitivity in Acute Myeloid Leukemia.

Objectives: Dual specificity phosphatase 1 (DUSP1) is high-expressed in various cancers and plays an important role in the cellular response to agents that damage DNA. We aimed to investigate the expressions and mechanisms of DUSP1 signaling pathway regulating cytarabine (Ara-C) resistance in acute myeloid leukemia (AML). Methods: Immunohistochemistry was performed on bone marrow biopsy specimens from AML and controls to explore the expression of DUSP1. Western blot and Q-PCR were used to detect the protein and mRNA expression levels. MTT assay was used to detect the proliferation of cells. Cell apoptosis was detected by flow cytometry. The immune protein-protein interaction (PPI) network of DUSP1 was analyzed in the platform of Pathway Commons, and immune infiltration analysis was used to study the immune microenvironment of AML. Results: We found that the expression levels of DUSP1 in AML patients exceeded that in controls. Survival analysis in public datasets showed that AML patients with higher levels of DUSP1 had poor clinical outcomes. Further public data analysis indicated that DUSP1 was overexpressed in NRAS mutated AML. DUSP1 knockdown by siRNA could sensitize AML cells to Ara-C treatments. The phosphorylation level of mitogen-activated protein kinase (MAPK) pathway was significantly elevated in DUSP1 down-regulated NRAS G13D mutated AML cells. The PPI analysis showed DUSP1 correlated with immune gene CREB1 and CXCL8 in NRAS mutated AML. We also revealed a correlation between tumor-infiltrating immune cells in RAS mutated AML microenvironment. Conclusion: Our findings suggest that DUSP1 signaling pathways may regulate Ara-C sensitivity in AML.

[Effect of shRNA-mediated silencing of CTGF and TIMP-1 on mRNA expression of CTGF, TIMP-1, and PC I and secretion of extracellular matrix in rat hepatic stellate cells].

To investigate the effect of short hairpin RNA (shRNA)-mediated silencing of CTGF and TIMP-1 in hepatic stellate cells (HSCs) on mRNA expression of TIMP-1, CTGF, and procollagen type-I (PC I), as well as secretion of extracellular matrix (ECM) proteins. Two recombinant expression plasmids harboring shRNAs against CTGF and TIMP-1 (psiRNA-GFP-CTGF and psiRNA-GFP-TIMP-1) were transfected alone or together into TGFb1-activated HSC-T6 cells. The mRNA expression levels of CTGF, TIMP-1, and PC I were detected by fluorescence quantitative PCR (FQ-PCR). The concentrations of secreted PC type-III, hyaluronate (HA), and laminin (LN) were measured by radioimmunoassay (RIA) of culture supernatants. FQ-PCR analysis showed that CTGFshRNA and TIMP-1shRNA specifically inhibited the expression of CTGF, TIMP-1, and PC I mRNA in activated HSC-T6 cells. The concentrations of secreted PC III, HA, and LN were decreased significantly in HSC-T6 cells with shRNA-silenced CTGF or TIMP-1 (P less than 0.01 or P less than 0.05). Moreover, HSC-T6 cells with shRNA-silenced CTGF and TIMP-1 showed a more robust decrease in synthesis of PC III, HA and LN (all, P less than 0.01), as well as in mRNA expression of PC I (P less than 0.05). CTGFshRNA and TIMP-1shRNA effectively inhibit expression of the respective target genes, as well as of PC I, and decrease secretion of ECM components from HSC-T6 cells. Silencing of both CTGF and TIMP-1 produces more robust effects than either in isolation. These data suggest that CTGF and TIMP-1 may be effective targets of shRNA-based gene therapy to treat liver fibrosis.

A systematic review and meta-analysis on the risk factors of acute myeloid leukemia.

Background: Acute myeloid leukemia (AML) is one of the main types of leukemia that threatens the life and health of patients. A large number of clinical studies have been conducted on the etiology of the disease. However, there are few evidence-based medical studies and no definitive treatment guidelines. Methods: Related articles were searched from Medline, Excerpta Medica Database (EMBASE), EBSCO, OVID, Chinese Biology Medicine Disc (CBMDISC), and Wanfang databases. The search time limit was from the establishment of the database to September 2021. The search terms were as follows: acute myeloid leukemia, AML, electromagnetic field, case-control study, cohort study, and risk factors. All literatures were included according to PICOS standards, and the risk of deviation and literature quality were assessed. RevMan 5.3 software was used for meta-analysis. Results: The 10 articles included were of high quality and low bias risk. The research results showed that compared with healthy people, among the risk factors for AML, family tumor history [risk ratio (RR) =0.98; 95% confidence interval (CI): (0.57, 1.69); Z=0.08; P=0.94] and the hepatitis B virus (HBV) infection rate [odds ratio (OR) =1.34; 95% CI: (0.57, 3.13); Z=0.68; P=0.50] showed no significant differences, but the hepatitis C virus (HCV) infection rate [OR =1.60; 95% CI: (1.17, 2.19); Z=2.92; P=0.003] and environmental exposure rate [OR =1.49; 95% CI: (1.01, 2.21); Z=2.02; P=0.04] increased significantly. Conclusions: A total of 10 articles were included to analyze AML risk factors and related content. The results suggested that HCV infection and environmental exposure history such as home decoration were risk factors for AML.

Prognostic nomogram and novel risk-scoring system for small cell lung cancer with different patterns of metastases.

OBJECTIVE: This research is aimed to develop the prognostic nomogram and novel risk-scoring system for small cell lung cancer (SCLC) with different patterns of metastases. METHODS: Data on SCLC patients were extracted from the 2010-2015 Surveillance, Epidemiology, and End Results (SEER) database. This nomogram prognostic model was confirmed in the validation cohort. C-index and calibration curve were used to evaluate the accuracy of nomogram model. The predictive capability and net benefit of nomogram was estimated by decision curve analysis (DCA). The cut-off point of the risk stratification system based on nomogram was assessed by X-tile analysis. RESULTS: Our Cox model indicated that age, gender, American Joint Committee on Cancer (AJCC) stage, metastases, chemotherapy, radiation and surgery were independent predictors for OS in SCLC patients. The C-index value of nomogram integrating significant variables for predicting OS in SCLC patients was 0.752 in SEER training set and 0.748 in SEER validation set, respectively. However, the TNM stage only had C-indexes of 0.464 and 0.472 for predicting OS, respectively. The nomogram prognostic model in this study showed higher C-indexes than those in the TNM stage. The C-index value and high quality of calibration plots indicate that the predictive ability of our nomogram model was of great superiority. DCA showed the nomogram had good clinical value. SCLC patients were further divided into low-risk and high-risk group according to nomogram predicted scores. CONCLUSION: Our nomogram model that integrated significant factors can aid as an individualized clinical predictive tool in SCLC patients.

Adipose-derived mesenchymal stem cell-secreted extracellular vesicles alleviate non-alcoholic fatty liver disease via delivering miR-223-3p.

Increasing studies have identified the potential of mesenchymal stem cell-derived extracellular vesicles (MSC-EVs) in non-alcoholic fatty liver disease (NAFLD) treatment. Hence, we further focused on the potential of adipose-derived MSC (ADSC)-EVs in NAFLD by delivering miR-223-3p. The uptake of isolated ADSC-EVs by hepatocytes was assessed, and the expression of miR-223-3p in ADSC-EVs and hepatocytes was characterized. It was established that miR-223-3p, enriched in ADSC-EVs, could be delivered by ADSC-EVs into hepatocytes. Using co-culture system and gain-of-function approach, we evaluated the effect of ADSC-EVs carrying miR-223-3p on lipid accumulation and liver fibrosis in pyrrolizidine alkaloids (PA)-induced hepatocytes and a high-fat diet-induced NAFLD mouse model. Bioinformatics websites and dual-luciferase reporter gene assay were performed to determine the interactions between miR-223-3p and E2F1, which was further validated by rescue experiments. ADSC-EVs containing miR-223-3p displayed suppressive effects on lipid accumulation and liver fibrosis through E2F1 inhibition, since E2F1 was demonstrated as a target gene of miR-223-3p. The protective role of ADSC-EVs by delivering miR-223-3p was then confirmed in the mouse model. Collectively, this study elucidated that ADSC-EVs delayed the progression NAFLD through the delivery of anti-fibrotic miR-223-3p and subsequent E2F1 suppression, which may suggest miR-223-3p-loaded ADSC-EVs to be a potential therapeutic approach for NAFLD.

Stochastic Petri Net Based Modeling of Emergency Medical Rescue Processes during Earthquakes.

The post-disaster emergency medical rescue (EMR) is critical for people's lives. This paper presents a stochastic Petri net (SPN) model based on the process of the rescue structure and a Markov chain model (MC), which is applied to the optimization of the EMR process, with the aim of identifying the key activities of EMR. An isomorphic MC model is developed for measuring and evaluating the time performance of the EMR process during earthquakes with the data of the 2008 Wenchuan earthquake. This paper provides a mathematical approach to simulate the process and to evaluate the efficiency of EMR. Simultaneously, the expressions of the steady state probabilities of this system under various states are obtained based on the MC, and the variations of the probabilities are analyzed by changing the firing rates for every transition. Based on the concrete data of the event, the authors find the most time consuming and critical activities for EMR decisions. The model results show that the key activities can improve the efficiency of medical rescue, providing decision-makers with rescue strategies during the large scale earthquake.

Serum Levels of Seven General Cytokines in Acute Brucellosis Before and After Treatment.

PURPOSE: Human brucellosis is the most common bacterial zoonosis globally that poses a severe health threat. Despite the availability of antibiotic therapy for human brucellosis, its tendencies of chronicity and persistence may lead to severe debilitating and disabling conditions in patients. Comprehensive understanding of the immune response in brucellosis will be helpful in improving the treatment strategies. In this study, we measured serum levels of T helper cell type 1 (Th1), Th2, and Th17 cytokines in patients with acute brucellosis before and after treatment. PATIENTS AND METHODS: Overall, 30 patients with acute brucellosis from the Beijing Di Tan Hospital and 26 healthy controls were enrolled in this study. All the patients received a 6-week therapy regimen comprising ceftriaxone, doxycycline, and rifampicin. Serum samples were collected from patients with acute Brucella infection and healthy controls before and after treatment. Serum seven cytokine levels of Th1 (IL-2, IFN-γ, and TNF-α), Th2 (IL-4, IL-6, IL-10), and Th17 (IL-17A) were measured using cytometric bead array. RESULTS: In patients with acute infection, the IL-2, IFN-γ, and IL-10 levels were significantly increased compared with those in healthy controls (P < 0.001). After treatment, IL-2, IFN-γ, and IL-10 levels significantly decreased (P < 0.05) and the TNF-α level significantly increased compared with the corresponding baseline levels and those in healthy controls (P < 0.05). Furthermore, the IFN-γ, IL-4, and IL-10 levels were higher in patients after treatment than in healthy controls (P < 0.05). IL-2 and IL-6 levels exhibited a positive correlation with the C-reactive protein (CRP) level in acute brucellosis (P < 0.05). CONCLUSION: Levels of most serum Th1 and Th2 cytokines were simultaneously increased in acute infection, followed by reduction in the corresponding cytokine levels and residual cytokine response during treatment. This residual immune response could represent a therapeutic opportunity that may improve the long-term clinical outcomes in patients with acute brucellosis after treatment.

TROP2 modulates the progression in papillary thyroid carcinoma.

Background: Tumor-associated calcium signal transducer 2 (TROP2) is over expressed in various kinds of human cancers and plays important roles in the proliferation, invasion and metastasis of tumor cells. However, the expression and molecular mechanism of TROP2 in thyroid papillary carcinoma (PTC) are unclear. Methods: The expressions of TROP2 in PTC and control tissue were detected by real-time reverse transcription polymerase chain reaction (RT-PCR) and immunohistochemistry. The proliferation and invasion of PTC cell lines were examined by cell cloning and transwell assays. RNA sequencing analysis and public data analysis were assessed to investigate the potential mechanisms of TROP2 in PTC. Gene correlation analysis was conducted to explore the association between TROP2 and the related gene ISG15 in patients with PTC. Results: The expression of TROP2 was significantly higher in PTC than control. The high expression of TROP2 protein was associated with lymph node metastasis, tumor size and capsular infiltration (P<0.05). SiRNA-mediated TROP2 gene expression silencing can significantly inhibit proliferation and migration of PTC cells. ISG15 decreased in TROP2 siRNA PTC cells and increased in PTC patients significantly. There was a significant correlation between the expression of TROP2 and ISG15 in PTC patients. TROP2 interacted directly with ATP6V1A, CEBPA and SOX5 and then further interacted with the immune genes. TROP2 expression and tumor-infiltrating immune cells were also correlated in thyroid cancer microenvironment. Conclusions: TROP2 promotes the development of PTC. TROP2 expression was correlated with ISG15 and tumor-infiltrating immune cells in thyroid cancer.

Safety and efficacy of allogeneic natural killer cell immunotherapy on human immunodeficiency virus type 1 immunological non-responders: a brief report.

BACKGROUND: Allogeneic natural killer (NK) cell immunotherapy is recognized as a promising anti-tumor strategy, but whether it plays a role in poor CD4 recovery among human immunodeficiency virus type 1 (HIV-1) infected patients is unknown. This study aimed to investigate the safety and effectiveness of allogeneic NK cells immunotherapy on HIV-1 immunological non-responders (INRs) receiving antiretroviral therapy (ART). METHODS: From February to April 2018, a prospective, randomized, controlled, open-label clinical trial, which enrolled 20 HIV-1 INRs following specific inclusion criteria, was conducted at Nankai University Second People's Hospital. Participants were randomly allocated (simple randomization 1:1) to either the combined treatment (NK + ART) group (n = 10) or the control (ART) group (n = 10). The allogenic highly activated NK cells from killer cell immunoglobulin-like receptor (KIR)/human leukocyte antigen (HLA)-Cw mismatched healthy donor were prepared (10 cells in each injection) and intravenously infused to each recruited patient of NK+ART group in three courses. Key immune parameters (CD4 count, CD8 count, CD4/CD8 ratio), laboratory tests (count of blood cells, biochemistry panel) and symptoms at baseline and at month 1, 3, 6, 9, 12, and 24 were measured/collected to analyze the safety and efficacy of the therapy. Comparisons were between the seven time-points of both groups using repeated measurement analysis of variance (ANOVA) test. Generalized estimating equations (GEE) model was performed to evaluate the overall effect of the NK+ART group vs. the ART group. RESULTS: From baseline to 24 months, we noted a mean CD4 count augmentation (139 to 243 cells/µL) in the NK + ART group and (144 to 176 cells/µL) in the ART group (difference, 67; 95% CI, 10 to 124; P = 0.024). Our estimations revealed that NK+ART group could improve CD4 level (ß = 54.59, P = 0.006) and CD8 level (ß = 322.47, P = 0.010) on average among the six measurements compared with the ART group. Only two (2/10, 20%) participants in the NK+ART group developed a transient mild fever after the first course. CONCLUSIONS: This preliminary study informs that HIV-1 INRs, allogenic NK cells immunotherapy is safe and could significantly improve CD4 recovery but not CD4/CD8 ratio. The practical effects, however, need long-term follow-up observations. Further study on the potential underlying mechanism is warranted.

Soluble IL-2Rα correlates with imbalances of Th1/Th2 and Tc1/Tc2 cells in patients with acute brucellosis.

BACKGROUND: Previous studies showed that soluble IL-2Rα is an important marker of cellular immune activation and might be a marker of treatment efficacy for children with brucellosis. However, data regarding adult patients with brucellosis were unknown. The aim of study was to explore the potential role of serum sIL-2Rα evaluating treatment responses in adult patients with brucellosis, and T cell immune status was also examined. METHODS: During January 2016-April 2017, 30 patients with acute brucellosis from the Third People's Hospital of Linfen in Shanxi Province and Beijing Di Tan Hospital, and 28 healthy controls were included in this study. Peripheral blood samples were collected before and after six weeks of antibiotic treatment. Serum sIL-2Rα levels were measured by enzyme-linked immunosorbent assay, and the percentage of Th1, Th2, Tc1, Tc2, and Tregs was detected by flow cytometry after intracellular staining for cytokines (interferon-γ and interleukin-4) and Foxp3 in T lymphocytes from peripheral blood. The obtained data were analyzed with Wilcoxon ranked sum tests for paired values, Mann-Whitney U-tests for comparisons between patients and healthy controls, and Spearman rank tests for correlation analyses. RESULTS: Serum sIL-2Rα levels were significantly higher in patients than in controls (P = 0.001). A significant decline was observed in patients after the cessation of treatment (P < 0.001) and return to normal (P > 0.05). Th1, Tc1, Th2, and Tc2 cell frequencies were higher in patients than in healthy subjects (P < 0.05), while the Th1/Th2 and Tc1/Tc2 ratios were significantly lower (P = 0.0305 and 0.0005, respectively) and returned to normal levels after treatment. In patients with acute brucellosis, serum sIL-2Rα levels were negatively correlated with the Th1/Th2 ratio (r = - 0.478, P = 0.028), Tc1/Tc2 ratio (r = - 0.677, P = 0.001), and Tc1 percentage (r = - 0.516, P = 0.017). Serum sIL-2Rα and Tc2 percentages were positively correlated (r = 0.442, P = 0.045). CONCLUSIONS: Based on the correlations with Th1/Th2 and Tc1/Tc2 ratios, serum sIL-2Rα levels may reflect the immune response status. sIL-2Rα may be a marker for therapeutic efficacy in acute brucellosis.

Serum levels of soluble CD163 and soluble CD14 following antibiotic therapy of patients with acute brucellosis.

INTRODUCTION: Soluble CD163 (sCD163) and soluble CD14 (sCD14) levels, monocyte/macrophage activation markers, are elevated in patient serum during Brucella infection. The aim of this study was to measure serum sCD163 and sCD14 levels during treatment for acute brucellosis to determine whether they can be used to monitor treatment efficacy. METHODOLOGY: Blood samples were collected from 30 patients with acute brucellosis (disease duration < 8 weeks) before and after 6 weeks of antibiotic therapy as well as from a comparison group of 28 healthy control individuals. Serum sCD163 and sCD14 levels were measured with specific, sandwich enzyme-linked immunosorbent assays. The clinical data and routine indices including C-reactive protein (CRP), erythrocyte sedimentation rates (ESR), as well as white cell counts (WBC) were also studied. RESULTS: Both serum sCD163 and sCD14 levels were significantly higher in patients with acute brucellosis than in healthy controls (p < 0.0001). A significant decline was observed in patients after cessation of treatment (p < 0.001), which still be significantly higher than that in healthy controls (p < 0.001). In additional, serum sCD163 levels were positively correlated with sCD14 levels; both of which were positively associated with CRP levels. However, neither sCD163 nor sCD14 levels were correlated with ESR or WBC. CONCLUSIONS: The decline in sCD163 and sCD14 levels following antibiotic therapy may be used as a marker to assess therapeutic efficacy following treatment of acute brucellosis.
