ABSTRACT

Objective:Donor cytomegalovirus (CMV) serological negative status may have an adverse effect on the outcome of allogeneic hematopoietic stem cell transplantation (allo-HSCT), while there is inadequate data for Chinese people. This study is to explore the impact of donor CMV serological status on the outcome of CMV seropositive patients receiving allo-HSCT.Methods:Our study retrospectively analyzed 16 CMV seropositive patients with hematological malignancies receiving allogeneic grafts from CMV seronegative donors (antibody IgG negative) at Peking University People′s Hospital from March 2013 to March 2020, which was defined as D -/R + group. The other 64 CMV seropositive patients receiving grafts from CMV seropositive donors at the same period of time were selected as matched controls through a propensity score with 1∶4 depending on age, disease state and donor-recipient relationship (D +/R + group). Results:Patients in D -/R + group developed CMV DNAemia later than patients in the D +/R + group (+37 days vs. +31 days after allo-HSCT, P=0.011), but the duration of CMV DNAemia in D -/R + group was longer than that of D +/R + group (99 days vs. 34 days, P=0.012). The rate of CMV reactivation 4 times or more in D -/R + group was 4/16, significantly higher than that of D +/R + group (4.7%, 3/64, P=0.01). The incidences of refractory CMV DNAemia (14/16 vs. 56.3%, P=0.021) and CMV disease (4/16 vs. 4.7%, P=0.01) in D -/R + group were both higher than those in D +/R + group. In addition, the application of CMV-CTL as the second-line antiviral treatment in D -/R + group was more than that in D +/R + group. Univariate analysis and multivariate analysis suggested that CMV serological negativity is an independent risk factor for refractory CMV DNAemia and the duration of CMV infection. The cumulative incidence of aGVHDⅡ-Ⅳ, cGVHD, 3-year probability of NRM, overall survival, and the cumulative incidence of relapse were all comparable in two groups. Conclusions:Although there is no significant effect on OS and NRM, the incidence of refractory CMV DNAemia, the frequency of virus reactivation, and the development of CMV disease in D -/R + group are higher than those in controls. Therefore, CMV seropositive donors are preferred for CMV seropositive patients.

ABSTRACT

The 11β-hydroxysteroid dehydrogenase type 1(11β-HSD1)is the only enzyme in the body, which can convert inactive cortisone(11-dehydrocorticosterone in rodents)to active cortisol(corticosterone in rodents)in vivo.And it is vital for regulating the level of active glucocorticoids in local tissues.It has been implicated that glucocorticoid dysregulations are closely related to various metabolic diseases, such as obesity and type 2 diabetes mellitus(T2DM), etc.Therefore 11β-HSD1 may be a potential target for the treatment of metabolic diseases.In this review, we summarize the biological function and tissue distribution of 11β-HSD1, discuss how 11β-HSD1 participates in physiological and pathological mechanisms of obesity, T2DM, non-alcoholic fatty liver disease, hypertension and sarcopenia, and sum up the advanced developments of 11β-HSD1 inhibitors.

ABSTRACT

Relapse is the main problem after allogeneic hematopoietic stem cell transplantation (allo-HSCT). The outcome of a second allo-HSCT (HSCT2) for relapse post-HSCT has shown promising results in some previous studies. However, little is known about the efficacy of HSCT2 in patients with relapsed/refractory acute leukemia (AL) post-chemotherapy plus modified donor lymphocyte infusion (post-Chemo + m-DLI) after the first allo-HSCT (HSCT1). Therefore, we retrospectively analyzed the efficacy of HSCT2 in 28 patients with relapsed/refractory AL post-Chemo + m-DLI in our center. With a median follow-up of 918 (457-1732) days, 26 patients (92.9%) achieved complete remission, and 2 patients exhibited persistent disease. The probabilities of overall survival (OS) and disease-free survival (DFS) 1 year after HSCT2 were 25.0% and 21.4%, respectively. The cumulative incidences of nonrelapse mortality on day 100 and at 1 year post-HSCT2 were 7.1% ± 4.9% and 25.0% ± 8.4%. The cumulative incidences of relapse were 50.0% ± 9.8% and 53.5% ± 9.9% at 1 and 2 years post-HSCT2, respectively. Risk stratification prior to HSCT1 and percentage of blasts before HSCT2 were independent risk factors for OS post-HSCT2, and relapse within 6 months post-HSCT1 was an independent risk factor for DFS and relapse post-HSCT2. Our findings suggest that HSCT2 could be a salvage option for patients with relapsed AL post-Chemo + m-DLI.

ABSTRACT

Objective:To investigate the differential expression of miRNAs during white adipose tissue(WAT)browning in mice under different stimulation conditions, and to analyze the potential regulatory mechanisms.Methods:Mouse models of subcutaneous WAT(sWAT)browning were established by different methods: cold-induced browning and intraperitoneal injection of CL316-243.HE staining and analysis of thermogenesis-related gene expression were used to validate the browning models.miRNAs expression profiles in different conditions were described by RNA-sequencing(RNA-seq)and miRNAs with similar expression patterns in the two groups were detected via screening.Target genes of miRNAs were predicted by bioinformatics, and their expression levels were verified by quantitative real-time PCR(qRT-PCR).Results:Both cold-induced browning and intraperitoneal injection of CL316-243 were able to activate the browning of sWAT, and the miRNA expression profile of sWAT showed significant differences before and after induction.After screening differentially expressed miRNAs, the expression of Mir-30E-3p was increased and the expression of Mir-181A-5p was decreased under different browning-inducing conditions in WAT.The prediction and validation of target genes revealed that cyclin-dependent kinase 6(Cdk6)and sirtuin 1(Sirt1)were potential targets regulated by miR-30e-3p and miR-181a-5p in the browning of sWAT, respectively.Conclusions:There are significant differences in miRNA expression during the browning of sWAT in mice induced by cold stimulation and CL316-243 injection.MiR-30e-3p and miR-181a-5p may be involved in the regulation of the sWAT browning process through target genes Cdk6 and Sirt1, respectively.

ABSTRACT

Objective:To explore the relationship between anti-human leukocyte antigen (HLA) antibodies and transplant outcomes in patients with hematological diseases who underwent matched sibling donor transplantation (MSDT).Methods:A retrospective analysis was conducted in 168 patients with hematological diseases who received MSDT in Peking University People's Hospital from March 2015 to November 2017. All patients received detection of anti-HLA antibodies before transplantation, and the correlation between anti-HLA antibodies and transplant outcomes such as hematopoietic cells implantation, blood product transfusion and prognosis after transplantation were analyzed.Results:Among the 168 patients, 28 (16.7%) were positive for anti-HLA class Ⅰ or class Ⅱ antibodies, and 14 (8.3%) were positive for both anti-HLA class Ⅰ and class Ⅱ antibodies. All patients received neutrophil engraftment, 164 patients (97.9%) received platelet engraftment. Univariate analysis showed that there were no effects of anti-HLA antibodies on neutrophil engraftment and engraftment time, platelet engraftment and engraftment time, the volume of red cell transfusion, the volume of platelet transfusion, overall survival (OS) rate, disease free survival (DFS) rate and transplant-related mortality (TRM) in patients with hematological diseases underwent MSDT (all P > 0.05). Multivariate analysis showed that platelet engraftment was associated with better OS ( HR=0.065, 95% CI 0.017-0.252, P < 0.01), better DFS ( HR=0.083, 95% CI 0.024-0.289, P < 0.01) and lower TRM ( HR=0.094, 95% CI 0.014-0.626, P=0.015). Conclusion:Anti-HLA antibodies have no effect on transplant outcomes of patients with hematological diseases who have received MSDT.

ABSTRACT

Objective To investigate the effect of fenofibrate on glucolipid metabolism and insulin sensitivity in lipoprotein lipase heterozygous knockout ( LPL+/-) mice, and to explore its mechanism. Methods LPL+/- mice and wild type ( WT) C57 mice were selected and divided into 3 groups ( n=6 each group):LPL+/-( FB) group, LPL+/-(W)group,andWTgroup.MiceinLPL+/-(FB)groupweregavagedwithfenofibrate(50mg·kg-1·d-1)for8 weeks. Mice in LPL+/-( W) and WT groups were orally fed with the same volume water as that in LPL+/-( FB) group for 8 weeks. Body weight was observed. Plasma triglyceride ( TG ) and free fatty acid ( FFA ) were measured. Intraperitoneal glucose tolerance test in 3 groups of mice were performed. The glucose area under the curve ( AUCG) and homeostasis model assessment for insulin resistance index ( HOMA-IR) were calculated. Insulin-stimulated Ser473 Akt phosphorylation in liver and skeletal muscle was measured by Western blot. Reactive oxygen species ( ROS) levels in liver and skeletal muscle were determined by dihydroethidium staining method and superoxide dismutase ( SOD) and catalase ( CAT) mRNA expression levels were detected by real-time PCR. Results Compared with LPL+/-( W) mice, body weight of LPL+/-( FB) mice was lowered, plasma TG and FFA levels were decreased by about 46.0%and 76.5%respectively, and fasting insulin level and HOMA-IR were decreased while there were no significant differences in fasting glucose level and AUCG between two groups. Insulin-stimulated Ser473 Akt phosphorylation levels in liver and skeletal muscle of LPL+/-mice were enhanced by fenofibrate. ROS level in skeletal muscle of LPL+/-( FB) mice was lower than that in LPL+/-( W) mice while there was no significant difference in ROS of liver between two groups. Fenofibrate significantly increased SOD and CAT mRNA expressions in skeletal muscle of LPL+/-mice, but not in liver. Conclusion Fenofibrate reduces body weight, ameliorates lipid metabolism, and improves insulin sensitivity in LPL+/- mice, with reduced oxidative stress.

ABSTRACT

Objective To evaluate the predictive value of posttreatment whole body scan (RxWBS) for radiation damage to the salivary glands in patients with differentiated thyroid carcinoma (DTC).Methods From April 2015 to June 2015,24 patients (8 males,16 females;age:26-64 years) with DTC,who accepted 131I therapy only one time and underwent Rx-WBS 2-4 d after 131I treatment,were recruited from the First Hospital of China Medical University.All patients had normal salivary glands function on salivary gland scintigraphy (SGS) performed on the day before 131I treatment,and 21 patients underwent SGS again 3 months after 131I treatment.The SGS results and clinical manifestations were used to evaluate the function of salivary glands after 131I therapy.Rx-WBS was analyzed by visual analysis and quantitative analysis (salivary gland to background uptake ratios,SUR).The SUR was compared between patient groups with different function of salivary glands.Mann-Whitney u test was used.Receiver operating characteristic (ROC) curve analysis was used to calculate the sensitivity of SUR for predicting the salivary gland damage.Results The SUR in dysfunctional parotid glands (n =12) was significantly higher than that in other glands with normal function (n=30;3.60(2.55,4.33) vs 2.75(2.33,3.29);z=-2.005,P<0.05).The SUR was not different between submandibular glands with lower function (n =15) and those with normal function (n=27;z=-0.144,P>0.05).The SUR of parotid glands (n =32) in patients with parotitis was significantly higher than that in others (n=16;3.16(2.53,4.01) vs 2.49(206,2 81);z=-3.073,P<0.05).The SUR of submandibular glands (n=28) in patients with sialadenitis was significantly higher than that in others (n=20;4.43(2.67,7.61) vs 2.93(1.92,4.65);z=-2.740,P<0.05).When 2.97 and 3.66 were selected as cutoff values,the sensitivities of SUR for predicting parotitis and sialadenitis were 59%(19/32) and 64% (18/ 28),respectively.Conclusion Rx-WBS may play a role in predicting radiation damage to the salivary glands.

ABSTRACT

Objective To investigate the impact of high mobility group box1 and GRACE score on the clinical prognosis of patients with acute coronary syndrome undergoing selective percutaneous coronary intervention. Methods A total of 380 consecutive patients initially diagnosed with acute coronary syndrome undergoing selec-tive PCI between January 2014 and March 2015 were included,with 200 of them assigned into low high mobility group box1(HMGB1<445 ng/mL)and the other 180 patients into high mobility group box1(HMGB1≥445 ng/mL).The baseline characteristics and laboratory indexes were collected on admission,GRACE score were calculat-ed at admission.The difference between the high and low high mobility group box1 were analzyed and the influenc-ing factors of patients with acute coronary syndrome undergoing selective percutaneous coronary intervention were studied. The mean follow-up period was 24 months,and the clinical end points were deaths from various causes and readmission for coronary heart disease. Results There were significantly differences statistically between the groups of high and low high mobility group box1 in clinical diagnosis. lipoprotein associated phospholipase A2, GRACE score,mean platelet volume,red cell distribution width,age,and left ventricular ejection fraction(P <0.05). The correlation analysis showed that HMGB1 was significantly related to lipoprotein associated phospholi-pase A2 and GRACE score,with the correlation coefficents of 0.575,0.836,respectively(P<0.05).COX analy-sis showed that HMGB1,lipoprotein associated phospholipase A2,GRACE score had statistical significance for survival outcomes(P<0.05),and the area under the ROC curve drawn by combining the three was 0.851(95% CI 0.811 ~ 0.891,P < 0.05). Conclusion There was a good correlation between HMGB1 and GRACE score. HMGB1 is a good predictor of clinical outcomes in the patients with acute coronary syndromes undergoing elective PCI treatment.

ABSTRACT

Objective@#To analyze the clinical value of real-time PCR for virus detection in the diagnosis and treatment of patients after allo-HSCT who had no infection evidence of pneumonia using routine pathogen detection panel.@*Methods@#The clinical data of 71 episodes with acute lung injury from May 2015 to March 2017 after allo-HSCT in hematology department of Peking University People’s Hospital (PKUPH) were retrospectively analyzed. PCR for virus detection and other routine pathogen detection tests were performed on bronchoalveolar lavage fluid (BALF) samples.@*Results@#Among 71 episodes with acute lung injury, a total of 15 patients were diagnosed as lower respiratory tract disease merely associated with virus (detection rate of 21.13%) , 19 episodes were absent of lower respiratory tract infection. The median time from allo-HSCT to the occurrence of lung injury were 176 (49-1 376) d and 196 (57-457) d respectively (z=-0.191, P=0.864) . There were no statistical differences for baseline characteristics and clinical features between two groups. The 100-day attributable mortalities were 13.3% (2/15) and 26.3% (5/19) (χ2=0.864, P=0.426) . Patients with low-dose steroids treatment had favorable outcome than those with high-dose steroids treatment (the dose of methylprednisolone ≥250 mg/d as standard) [4.2% (1/24) vs 60.0% (6/10) ]. In patients with detectable virus in BALF, 2 patients died with early high-dose steroids treatment, while 11 patients survived with no steroids treatment or late application.@*Conclusions@#Virus infection should be considered in post-HSCT pneumonia patient with negative result using routine pathogen detection panel. Expanding virus detection panel by PCR in BALF could increase diagnostic precision and might be instructive to treatment.

ABSTRACT

Objective@#To investigate the clinical significance of PCR detection of human herpesvirus 6 (HHV6) in gastro biopsy on the course of diarrhea in patients with severe diarrhea after allogeneic hematopoietic stem cell transplantation (HSCT) .@*Methods@#Data from a cohort of 45 HSCT recipients (including age, sex, transplantation conditions, graft-versus-host disease, treatments, clinical signs, outcome, HHV6, and other infections) performed between 2015 and 2016 were collected. Univariate analysis was used to evaluate influences between the different parameters.@*Results@#Of the 45 enrolled recipients, 21 patients (46.7%) presented HHV6 positive in gastro-biopsy during the analyzed period. The incidence of CMV viremia in the positive HHV6 group was comparable with that in the negative HHV6 group. But the incidence of EBV viremia in the positive HHV6 group was significantly higher than in the negative HHV6 group (P=0.028) . 44 out of 45 patients with severe diarrhea were given antiviral treatment with foscarnet and/or ganciclovir, the latter didn’t influence the course of the diarrhea.@*Conclusions@#Positive PCR results in GI tract samples didn’t necessarily reflect reactivation of HHV6. Further studies are needed to define the significance of HHV6 for GI tract symptoms after allo-HSCT.

ABSTRACT

Objective To investigate the glucolipid metabolism in lipoprotein lipase (LPL) gene knockout mice, and to explore the possible mechanisms of insulin resistance. Methods 16- and 40-week old LPL gene knockout heterozygous mice( LPL + / -) and wild type ( WT) C57 mice were selected and divided into 4 groups:16-week LPL+ / -(n=6), 16-week WT(n = 6), 40-week LPL+ / -(n = 6), and 40-week WT(n = 6) group. LPL activity of post-heparin serum was examined. Serum triglyceride( TG) and free fatty acid( FFA) were measuzed. Intraperitoneal glucose tolerance test(IPGTT) in 4 groups of mice were performed. The glucose area under the curve (AUCG) and homeostasis model assessment for insulin resistance index and β-cell function index ( HOMA-IR, HOMA-β) were calculated to evaluate insulin sensitivity and the function of islet β-cells. Serum malondialdehyde (MDA) and total antioxidant capacity ( TAOC) levels were determined by means of colorimetric method. Using dihydroethidium( DHE) fluorescent staining method, reactive oxygen species ( ROS) levels in liver and skeletal muscle were determined. Results LPL activity levels of both 16- and 40-week LPL+ / - mice were significantly lower than that in WT mice of the same age. Serum TG and FFA of 40-week old LPL+ / - mice were significantly higher than those in WT mice of the same age(P<0. 05), and they were also higher than those of 16-week old LPL+ / - mice(P<0. 05). IPGTT showed that compared with WT mice, blood glucose level in LPL+ / - mice was significantly higher than that in WT group at 30 and 120 minute(P<0. 05), and fasting insulin and HOMA-IR were increased significantly(P<0. 05). Serum MDA of 40-week old LPL+ / - mice was evidently higher than that in WT mice by the same week(P<0. 05), while TAOC level was lower than that of WT mice (P<0. 05). ROS in skeletal muscle of 16-week old LPL+ /- mice was significantly increased. Meanwhile, ROS in both liver and skeletal muscle of 40-week old LPL+ / - mice was significantly higher than that in WT mice of the same age. Conclusion As time goes by, lipid and glucose disorders of LPL+ / - mice are aggravating, and insulin resistance develops evidently. Insulin resistance in LPL+ / -mice with dyslipidemia may be related to oxidative stress.
