ABSTRACT

OBJECTIVE@#To investigate the effects of decitabine (DEC) combined with all-trans retinoic acid (ATRA) on the number of immune cells, efficacy and adverse reactions in the treatment of myeloid neoplasms patients.@*METHODS@#Eighty-four patients with myeloid tumors, including AML, MDS-EB-1 or MDS-EB-2 treated by the regimen containing decitabine in our hospital from January 2009 to October 2019 were enrolled and retrospectively analyzed, among the patients, 21 patients treated with DEC alone, 24 patients treated with DEC combined with ATRA (DEC/ATRA) and 39 patients treated with DEC combined with G-CSF priming regimen (DEC/priming). The changes of peripheral blood immune cell levels before and after treatment of the patients between the three groups were compared, and the differences in clinical efficacy and adverse reactions of the patients between the three groups were also compared.@*RESULTS@#There was no statistical differences in the number of immune cells among the patients in the three groups before treatment (P>0.05). NK cell levels decreased significantly in the patients in DEC and DEC/ATRA group after treatment (P<0.05); After treatment, the levels of CD8+ and CD3+T cells in the patients treated by DEC /priming regimen significantly increased (P<0.05), while the levels of CD3-HLA-DR+ B cells significantly decreased (P<0.05). The overall response rate (ORR) of the patients in DEC/ATRA group (75%) and DEC/priming group (74.36%) was significantly higher than 42.86% in DEC monotherapy group, and the differences showed statistically significant (P<0.05), while the ORR between the patients in DEC/ATRA and DEC/priming group showed no statistic differences (P>0.05). There were no statistical differences in overall survival (OS) and incidence of bleeding between the patients in the three groups (P>0.05). The incidences of grade 3 to 4 bone marrow suppression and the infection rate of the patients in DEC monotherapy and DEC/ATRA group were significantly lower than that in DEC/priming regimen group after treatment (all P<0.05), however, there was no statistical difference between DEC monotherapy and the DEC/ATRA group.@*CONCLUSION@#The efficacy of DEC/ATRA on myeloid neoplasms is comparable to that of DEC/priming regimen, and the anti-myeloid tumor effect of DEC/ATRA regimen may be related to the regulation of NK cells and T cells.

ABSTRACT

OBJECTIVE@#Traditional epidemiological studies have shown that C-reactive protein (CRP) is associated with the risk of cardiovascular diseases (CVDs). However, whether this association is causal remains unclear. Therefore, Mendelian randomization (MR) was used to explore the causal relationship of CRP with cardiovascular outcomes including ischemic stroke, atrial fibrillation, arrhythmia and congestive heart failure.@*METHODS@#We performed two-sample MR by using summary-level data obtained from Japanese Encyclopedia of Genetic association by Riken (JENGER), and we selected four single-nucleotide polymorphisms associated with CRP level as instrumental variables. MR estimates were calculated with the inverse-variance weighted (IVW), penalized weighted median and weighted median. MR-Egger regression was used to explore pleiotropy.@*RESULTS@#No significant causal association of genetically determined CRP level with ischemic stroke, atrial fibrillation or arrhythmia was found with all four MR methods (all Ps > 0.05). The IVW method indicated suggestive evidence of a causal association between CRP and congestive heart failure ( OR: 1.337, 95% CI: 1.005-1.780, P = 0.046), whereas the other three methods did not. No clear pleiotropy or heterogeneity were observed.@*CONCLUSIONS@#Suggestive evidence was found only in analysis of congestive heart failure; therefore, further studies are necessary. Furthermore, no causal association was found between CRP and the other three cardiovascular outcomes.

ABSTRACT

Objective:To investigate the influencing factors for hepatic artery complica-tions of liver transplantation from donation after citizen's death.Methods:The retrospective cohort study was conducted. The clinicopathological data of 147 recipients who underwent liver transplan-tation from donation after citizen's death in Xijing Hospital of Air Force Military Medical University from January 2015 to June 2020 were collected. There were 109 males and 38 females, aged (46±12)years. All recipients underwent liver transplantation from donation after citizen's death. Observation indicators: (1) surgical situations; (2) occurrence of hepatic artery complications after liver transplantation; (3) analysis of donor related influencing factors for hepatic artery complications after liver transplantation; (4) analysis of recipient related influencing factors for hepatic artery complications after liver transplantation; (5) follow-up. Follow-up was conducted using outpatient examination or telephone interview to detect survival of recipients up to June 2021. Measurement data with normal distribution were represented as Mean± SD. Measurement data with skewed distribution were represented as M(range). Univariate analysis was conducted using the Fisher exact probability, and multivariate analysis was conducted using the COX regression model. Kaplan-Meier method was used to calculate the cumulative survival rate and draw the survival curve. Results:(1) Surgical situations: of the 147 recipients, 108 cases underwent orthotopic liver transplantation, and 39 cases underwent piggyback liver transplantation. The operation time of 147 recipients was (458±101)minutes. (2) Occurrence of hepatic artery complications after liver transplantation: 4 of the 147 recipients had hepatic artery complications, including 3 cases with hepatic artery embolism and 1 case with hepatic artery stenosis. The time to occurrence of hepatic artery complications after liver transplantation was (5±2)days. (3) Analysis of donor related influencing factors for hepatic artery complications after liver transplantation: results of univariate analysis showed that age, atherosclerosis, fatty liver and arterial variation were not donor related factors influencing hepatic artery complications after liver transplantation ( P>0.05). (4) Analysis of recipient related influencing factors for hepatic artery complications after liver transplantation: results of multivariate analysis showed that insufficient hepatic artery blood flow in the recipient was an independent risk factor for hepatic artery complications after liver transplantation ( hazard ratio=10.13, 95% confidence interval as 1.05-97.42, P<0.05). (5) Follow-up: 146 of the 147 recipients were followed up for 1 to 77 months, with a median follow-up time of 34 months. The 1-year cumulative survival rate of the 146 recipients was 92.2%. Conclusion:Insufficient hepatic artery blood flow of the recipient is an independent risk factor for hepatic artery complications after liver transplantation from donation after citizen's death.

ABSTRACT

The present study investigated the effects and mechanisms of Jiaotai Pills on depressed mice induced by chronic unpredictable mild stress(CUMS). The CUMS-induced depression model mice were established and the depression behaviors of mice were evaluated by sucrose preference test, open field test, tail suspension test, and forced swimming test. Molecular docking was employed to simulate the interaction of six main active ingredients in Jiaotai Pills with SIRT1. Immunohistochemical staining was used to detect the level of SIRT1 in the hippocampus of mice. Western blot was used to detect the protein expression levels of SIRT1, p-NF-κB p65, NF-κB p65, and FoxO1 in the hippocampus of mice. Enzyme-linked immunosorbent assay(ELISA) kits were used to detect the levels of interleukin(IL)-1β, IL-6, tumor necrosis factor-α(TNF-α), and brain-derived neurotrophic factor(BDNF) in the hippocampus and serum of mice. Biochemical kits were used to detect superoxide dismutase(SOD) activity and malondialdehyde(MDA) and glutathione(GSH) levels in the hippocampus and serum of mice. Liquid chromatography-tandem mass spectrometry(LC-MS/MS) was used to detect the levels of dopamine(DA), 5-hydroxytryptamine(5-HT), and norepinephrine(NE) in the hippocampus and serum of mice. The results showed that the sucrose preference rate, movement distance, and the number of crossing centers were reduced in the model group(P<0.01), and the tail suspension time and swimming immobility time were increased(P<0.01). Molecular docking results indicated good binding of six main active ingredients in Jiaotai Pills to SIRT1. In the hippocampus, the expression level of SIRT1 was reduced(P<0.01), and the levels of p-NF-κB p65/NF-κB p65 and FoxO1 were increased(P<0.01). In the hippocampus and serum, the levels of IL-1β, IL-6, TNF-α, and MDA were increased(P<0.01), and the activity of SOD and the levels of GSH, DA, 5-HT, NE, and BDNF were reduced(P<0.01). The treatment with high-dose Jiaotai Pills increased the sucrose preference rate, movement distance, and the number of crossing centers(P<0.05), reduced tail suspension time and swimming immobility time(P<0.01), elevated hippocampal SIRT1 expression level(P<0.01), decreased hippocampal and serum IL-1β, IL-6, TNF-α, and MDA levels(P<0.01), potentiated SOD activity, and up-regulated GSH, DA, 5-HT, NE, and BDNF levels in the hippocampus and serum(P<0.05, P<0.01) in model mice. In conclusion, the results showed that Jiaotai Pills could improve the depression behaviors of model mice with CUMS-induced depression, and the underlying mechanism was related to the up-regulation of SIRT1 in the hippocampus of mice to exert anti-inflammatory and anti-oxidative stress effects.

ABSTRACT

Endogenously eliminating the hematoma is a favorable strategy in addressing intracerebral hemorrhage (ICH). This study sought to determine the role of retinoid X receptor-α (RXR-α) in the context of hematoma absorption after ICH. Our results showed that pharmacologically activating RXR-α with bexarotene significantly accelerated hematoma clearance and alleviated neurological dysfunction after ICH. RXR-α was expressed in microglia/macrophages, neurons, and astrocytes. Mechanistically, bexarotene promoted the nuclear translocation of RXR-α and PPAR-γ, as well as reducing neuroinflammation by modulating microglia/macrophage reprograming from the M1 into the M2 phenotype. Furthermore, all the beneficial effects of RXR-α in ICH were reversed by the PPAR-γ inhibitor GW9662. In conclusion, the pharmacological activation of RXR-α confers robust neuroprotection against ICH by accelerating hematoma clearance and repolarizing microglia/macrophages towards the M2 phenotype through PPAR-γ-related mechanisms. Our data support the notion that RXR-α might be a promising therapeutic target for ICH.

ABSTRACT

An essential step for cancer vaccination is to break the immunosuppression and elicit a tumor-specific immunity. A major hurdle against cancer therapeutic vaccination is the insufficient immune stimulation of the cancer vaccines and lack of a safe and efficient adjuvant for human use. We discovered a novel cancer immunostimulant, trichosanthin (TCS), that is a clinically used protein drug in China, and developed a well-adaptable protein-engineering method for making recombinant protein vaccines by fusion of an antigenic peptide, TCS, and a cell-penetrating peptide (CPP), termed an "all-in-one" vaccine, for transcutaneous cancer immunization. The TCS adjuvant effect on antigen presentation was investigated and the antitumor immunity of the vaccines was investigated using the different tumor models. The vaccines were prepared

ABSTRACT

BACKGROUND@#Many Parkinson disease (PD) patients complain about chronic fatigue and sleep disturbances during the night. The objective of this study is to determine the relationship between fatigue and sleep disturbances by using polysomnography (PSG) in PD patients.@*METHODS@#Two hundred and thirty-two PD patients (152 with mild fatigue and 80 with severe fatigue) were recruited in this study. Demographic information and clinical symptoms were collected. Fatigue severity scale (FSS) was applied to evaluate the severity of fatigue, and PSG was conducted in all PD patients. FSS ≥4 was defined as severe fatigue, and FSS <4 was defined as mild fatigue. Multivariate logistic regression and linear regression models were used to investigate the associations between fatigue and sleep disturbances.@*RESULTS@#Patients with severe fatigue tended to have a longer duration of disease, higher Unified Parkinson Disease Rating Scale score, more advanced Hoehn and Yahr stage, higher daily levodopa equivalent dose, worse depression, anxiety, and higher daytime sleepiness score. In addition, they had lower percentage of rapid eye movement (REM) sleep (P = 0.009) and were more likely to have REM sleep behavior disorder (RBD) (P = 0.018). Multivariate logistic regression analyses found that the presence of RBD and proportion of REM sleep were the independent predictors for fatigue. After the adjustment of age, sex, duration, body mass index, severity of disease, scores of Hamilton Rating Scale for Depression, Hamilton Anxiety Rating Scale, and other sleep disorders, proportion of REM sleep and degree of REM sleep without atonia in patients with PD were still associated with FSS score.@*CONCLUSION@#Considering the association between fatigue, RBD, and the altered sleep architecture, fatigue is a special subtype in PD and more studies should be focused on this debilitating symptom.

Objective To study the clinical significance of globus pallidus signal intensity and the intensity ratio of globus pallidus and putamen (G/P ratio) on magnetic resonance T1WI for the early recognition of neonatal bilirubin encephalopathy.Method From January to December 2017,full-term neonates with hyperbilirubinemia admitted to the neonatology department of our hospital were enrolled in the case group,and full-term neonates without hyperbilirubinemia in the control group.The clinical data,globus pallidus T1WI signal intensity,G/P ratio and the follow-up data were collected.According to the level of hyperbilirubinemia,the neonates in the case group were further assigned into mild hyperbilirubinemia group (serum bilirubin:222 to <256 μmol/L),moderate hyperbilirubinemia group (serum bilirubin:256 to <342 μmol/L),and severe hyperbilirubinemia group (serum bilirubin:≥ 342 μmol/L).According to the injury score of ABE,the neonates with ABE were assigned into mild ABE group,moderate ABE group and severe ABE group.The correlation of globus pallidus T1WI and T2WI signal values,G/P ratio and the serum bilirubin level and ABE degree were analyzed;receiver operating characteristic (ROC) curve was drawn to explore the predictive value of the T1WI signal value and G/P ratio for the diagnosis of ABE;the changes of globus pallidus T1WI and T2WI signal values during the first 6 months after birth and the results of follow-up to 1 year after discharge were also analyzed.Result A total of 175 neonates were included in the case group (65 in the mild hyperbilirubinemia group,71 in the moderate hyperbilirubinemia group and 39 in the severe hyperbilirubinemia group) and 43 neonates in the control group.39 neonates were diagnosed as ABE (21 mild ABE,12 moderate ABE,and 6 severe ABE).The first T1WI signal value and G/P ratio of neonates in the severe hyperbilirubinemia group was higher than the moderate hyperbilirubinemia group,the mild hyperbilirubinemia group and the control group;the T1WI signal value and G/P ratio in the moderate hyperbilirubinemia group was higher than the mild hyperbilirubinemia group and the control group (P < 0.05).No significant difference existed between the mild group and the control group(P > 0.05).T2WI values showed no differences among neonates with different bilirubin levels (P > 0.05).The first T1WI signal value and G/P ratio in the severe ABE group were significantly higher than the moderate and mild ABE group,and the moderate ABE group higher than the mild ABE group (P < 0.05).The ROC curve indicated the optimal cut-off value of T1WI signal and G/P ratio were 628 and 1.38,respectively.Among all the 175 neonates,9 had a decrease in T1WI signal value and an increase in T2WI signal value at 6 months after birth.After 1 year of follow-up visits,7 children were finally diagnosed as chronic bilirubin encephalopathy.All these children had increased signal intensity on T1WI in the acute phase,plus a decreased T1WI signal and an increased T2WI signal in 1 ~ 6 months after birth.Conclusion The globus pallidus T1WI signal and G/P ratio are closely related to the serum bilirubin level and ABE severity.If T1WI signal value > 628 or G/P value > 1.38,ABE should be considered.The T1WI signal value and G/P ratio play important roles as indicators for the early recognition of neonatal bilirubin encephalopathy.

ABSTRACT

Objective:To investigate the clinical significances of CD4/CD8 ratio and neutrophil-to-lymphocyte ratio (NLR) in patients with multiple myeloma (MM).Methods:The clinical data of 124 MM patients in the Third Affiliated Hospital of Soochow University from December 2002 to April 2017 were retrospectively analyzed, and 31 healthy people were chosen as the controls. Peripheral blood T lymphocyte subsets were detected by using flow cytometry, and the correlations between CD4/CD8 ration and related clinical indicators were also investigated. All MM patients were divided into the high NLR group and the low NLR group according to the media of NLR, and the correlation of them with related clinical indicators, chromosome karyotype, overall survival (OS) and progression-free survival (PFS) was also compared.Results:Compared with the healthy control group, the proportion of CD4 + T cells [(35.28±6.58)% vs. (31.85±6.76)%, t = -2.067, P = 0.043], absolute value of NK cells [0.22×10 9/L (0.13×10 9/L-0.59×10 9/L) vs. 0.17×10 9/L (0.00×10 9/L-0.42×10 9/L), Z = -2.614, P = 0.009] and CD4/CD8 ratio [0.97 (0.50-2.69) vs. 0.81 (0.30-1.28), Z = -2.253, P = 0.024] was decreased, respectively. The proportion of CD8 + cells was increased [(36.93±7.38)% vs. (40.50±6.50)%, t = 2.074, P = 0.042] in MM group. The hemoglobin level of CD4/CD8 ratio ≥0.94 group was higher than that of CD4/CD8 ratio <0.94 [(98.89±21.35) g/L vs.(80.60±23.23) g/L, t = -2.066, P = 0.047]. Compared with the healthy control group, NLR was increased in MM group [1.54 (1.10-3.23) vs. 1.95 (0.29-12.70), Z = -2.384, P = 0.017]. Compared with the low NLR group (<1.95), serum β 2-microglobulin [4.56 mg/L (1.63-12.60 mg/L) vs. 6.17 mg/L (1.58-67.50 mg/L), Z = -2.586, P = 0.010] and serum creatinine [84.5 μmol/L (43.0-376.5 μmol/L) vs. 113.0 μmol/L (46.5-754.0 μmol/L), Z = -3.866, P < 0.001] was increased in the high NLR group for MM patients. The proportion of the male patients, β 2-microglobulin > 5.5 mg/L, serum creatinine > 177 μmol/L, stage Ⅲ of international staging system (ISS) in the high NLR group was higher than that in the low NLR group (all P < 0.05), and there was no statistically significant difference in the composition of chromosome karyotype (all P > 0.05). The median OS time in the low NLR group was longer than that in the high NLR group [30 months (20-40 months) vs. 17 months (7-27 months), χ 2 = 4.519, P = 0.034], and there was no statistically significant difference in the PFS of both groups ( P > 0.05). Multivariate Cox analysis demonstrated that the age, corrected serum calcium, serum creatinine, lactic dehydrogenase were the independent influencing factors of OS in MM (all P < 0.05), while NLR wasn′t an independent influencing factor of OS in MM ( P = 0.513). Conclusions:CD4/CD8 ratio is decreased and immune dysfunction occurs in MM patients. MM patients with high NLR have a shorter OS time.

ABSTRACT

Objective@#To evaluate possible effects of Gelctin-9 on acute graft versus host disease (aGVHD) development and clinical outcomes in patients before and afer allogeneic hematopoietic stem cell transplantation (allo-HSCT) .@*Methods@#Peripheral blood samples were obtained from 29 patients and 15 healthy volunteers with heparin anticoagulant tubes. Samples were analyzed using ELISA kits to measure the serum concentrations of Galectin-9.@*Results@#Patients developing aGVHD had significantly lower level of Galectin-9 [ (7.96±1.18) μg/L] before allo-HSCT compared with those not developing aGVHD [ (12.37±0.97) μg/L, P<0.001]. And after allo-HSCT, the consentration of Galectin-9 increased markedly in patients developing aGVHD [ (17.78±1.78) μg/L] compared with those not developing aGVHD [ (9.45±0.80) μg/L, P<0.001]. Patients developing 3-4 grade aGVHD had significantly higher level of Galectin-9 [ (23.25±2.59) μg/L] compared with those developing 1-2 grade aGVHD [ (14.37±1.45) μg/L, P=0.008] and those without aGVHD [ (9.45±0.80) μg/L, P<0.001]. The patients with lower level of Galectin-9 after allo-HSCT (<13.61 μg/L) showed more favorable clinical outcomes compared with those with higher level of Galectin-9 (≥13.61 μg/L) . The 3-year overall survival rates were (100.00±6.05) % and (69.23±12.80) %, respectively (P=0.009) . The cumulative incidence of non-relapse mortality was significantly higher in high Galectin-9 group [ (23.08±11.69) %] in comparison with low Gaelctin-9 group [ (0.00±7.39) %] (P=0.023) . There was no significant difference between the two groups in terms of the cumulative incidence of relapse. The cumulative incidence of relapse at 3 years were (8.33±7.98) % and (12.50±8.27) % in high and low Galectin-9 groups, respectively (P=0.708) .@*Conclusions@#The serum concentration of Galectin-9 at the time of engraftment after allo-HSCT may be used as a predictor for the development and severity of aGVHD. Galectin-9 might be considered as a potential new approach to regulate transplant rejection to achieve desirable survival.
