ABSTRACT
AIM: To evaluate the clinical efficacy and safety of oral proteasome inhibitor ixazomib in the treatment of multiple myeloma. METHODS: Eighty patients with multiple myeloma treated with ixazomib-containing therapy in the department of hematology, the First Affiliated Hospital of Anhui Medical University from January 2019 to December 2020 were retrospectively analyzed, including 38 patients with relapsed/refractory multiple myeloma (RRMM)and 42 patients who switched treatment due to adverse events (AEs) after initial induction therapy with bortezomib. Treatment was a two-drug or three-drug regimen containing ixazomib, and the clinical efficacy and safety of ixazomib were evaluated. RESULTS: The overall response rate (ORR) of relapsed/refractory patients was 50%, ≥ VGPR 21.05%; the ORR of patients who switched treatment was 83.33%, compared with the ORR before switching (78.57%), the response rate was further improved, of which 45.24%(19/42) patients had deepened response; the main hematological AEs included granulocyte and platelet count reduction and anemia, non-hematological AEs were mainly diarrhea and fatigue. CONCLUSION: Ixazomib shows good clinical efficacy and safety in patients with RRMM and bortezomib-intolerant MM.
ABSTRACT
Objective To describe the cardiovascular risk profile of inpatients with schizophrenia and estimate the 10-year CVD risk in schizophrenia patients. Methods Four hundred sixty-six randomly selected cases of schizophrenia patients and 507 health controls were included in the study. Body mass index (BMI), Fasting blood glucose (FBG), triglyceride (TG),,total cholesterol (TC), smoking rate (smoking people/total people), Framing-ham Risk Score (FRS), high density lipoprotein-cholesterol (HDL-C) and age of the vessel (VA). The 10-year cardiovascular risk(FRS) and age of the vessel (VA) were assessed using the Framing-ham Risk Score. Results 10-year CVD risk was significantly higher in patients with schizophrenia than in control group [(6.71 ±6.95)％ vs. (4.76 ±3.07)％], (P<0.05). Comparing with the control group, smoking prevalence[(41％) vs. (19％)], MS[(25％) vs. (17％)], BMI[(23.67 ±3.61)kg/m2 vs. (21.73±4.11)kg/m2] and VA[(46.7±15.3) vs. (43.7±9.8)] were higher in patients group. SBP[(119.86±14.90)mmHg vs. (128.10±15.41)mmHg] and HDL-C [(1.08±0.27)mmol/L vs. (1.38±0.22)mmol/L] were lower in patients group than in the healthy controls. The FRS score of the patient group was positively correlated with BMI, FBG level and SBP, waist circumference and smoking index (P<0.05) and was negatively correlated with the levels of HDL-C. Multivariate Linear Regression analysis demonstrated that FRS was correlated with FBG (β=0.181,P<0.01)、SBP (β=0.149,P<0.01)、HDL-C (β=-0.107,P<0.01) and smoking index(β=0.554,P<0.01). Conclusion The risk of cardiovascular disease in patients with schizophrenia over the next 10 years is 6.7％, which is significantly higher compared with the control group. Fasting blood glucose, systolic blood pressure, high density lipoprotein, smoking may be associated with 10-year CVD risk of schizophrenia patients.
ABSTRACT
Objective:To investigate the serum level of IL-34 in patients with acute phase Henoch-Schoenlein purpura ( HSP) and its potential significance .Methods:38 HSP patients were recruited ,together with 21 healthy volunteers as control .The serum level of IL-34,IL-6 and TNF-αwere determined using enzyme-linked immunosorbent assay (ELISA) or chemiluminescence.The correlation analysis was performed to explore the correlation of IL-34 with clinical parameters and the serum level of IL-6,TNF-α.Results:The se-rum levels of IL-34,IL-6 and TNF-αin HSP patients were significantly higher as compared to the control group (P<0.001).The serum level of IL-34 was positively correlated with that of high sensitive C-reactive protein ( hs-CRP) and IL-6 ( r=0.453 ,P=0.004 and r=0.469,P=0.003,respectively).Conclusion:IL-34 might be involved in the pathogenesis of HSP ,and the potential mechanisms of ac-tion is associated with the aberrant expression of pro-inflammatory factors in HSP ,which promote the development of inflammation in the vascular system.
ABSTRACT
Objective To investigate the correlated factors of prognosis for acute myeloid leukemia (AML).Methods A retrospective analysis of initial 182 patients with AML was performed to assess the relationship between prognostic factors including sex,age,white cell count at diagnosis,immunophenotype,cytogenetics,allo-HSCT and complete remission (CR) after one-course of induction and overall survival (OS) or event free survival (EFS).Results The median age of 182 patients was 49 (14-80) years old,and the median follow up was 9.7 (0.5-75.5) months.There were 107 patients achieved CR after one-course of induction (total response rate was 65.9 ％,120/182),age≥60 years.CD64 negative,unfavorable cyto-genetics and failing to achieve CR after one-course of induction were associated with lower total CR rate.Univariate analysis results demonstrated that age ≥60 years,unfavorable cytogenetics,CD11b expression and failing to achieve CR after one-course of induction had poor influence on 3-years OS and EFS,while the 3-years OS and EFS for patients with CD19 expression,CD64 expression and allo-HSCT were better than that of the patients with negative CD19 and CD64.Multivariate analysis suggested that age,cytogenetics,CD11b,CD64,allo-HSCT and CR after one-course of induction were independent prognostic factors for OS,while cytogenetics,CD64,allo-HSCT and CR after one-course of induction were important on EFS.Conclusions Prognostic analysis depending on AML corelation factors is benifit to individual therapy and can be applied to improve the survival.

ABSTRACT
Objective To analyze the clinical characteristics and prognostic factors in patients with primary gastrointestinal diffuse large B-cell lymphoma (PGI-DLBCL),and to improve the diagnosis and treatment of PGI-DLBCL.Methods Retrospective analysis was conducted in 51 cases of PGI-DLBCL between January 2009 and August 2013.The data included clinical manifestations,pathological features,treatment regimens and prognosis.Results 51 patients included 31 males and 20 females,the range of ages was from 16 to 80 years old,median age was 48 years old.The major clinical presentation were abdominal pain,abdominal distension,abdominal mass,nausea and vomiting,abdominal mass.The occurrences in stomach,small intestine,colon,rectum and multiple involvement were 56.86 ％,29.41％,7.84 ％,1.90 ％ and 3.92 ％ respectively.The mass bigger than 10 cm was found in 13 cases (25.49 ％).47.06 ％ (24/51) of the cases belonged to the GCB subtype and 52.94 ％ (27/51) belonged to the non-GCB subtype.There was no significant impact of lymphoma cell origin,disease distribution (stomach or intestinal) and mass on prognosis of lymphoma treatment.The univariate analysis revealed that the patients with Lugano stage Ⅳ,increased level of serum lactate dehydrogenase (LDH),modified-international prognosis index (modified IPI) 3-5 and increased level of CA125 had poor prognosis (all P ＜ 0.05).There was no difference of survival rate between patients treated with rituximab plus chemotherapy and single CHOP like therapy.Surgery plus postoperative chemotherapy significantly improved survival of patients treated with simple chemotherapy (P ＞ 0.05).Conclusion The clinical Lugano stage,IPI score,increased LDH and CA125 are important prognostic factors of PGI-DLBCL.
ABSTRACT
Objective To find out the impact of SHI-1 cells on VOCs in the headspace, and to assess the feasibili-ty of VOCs analysis in leukemia patients or with other tumors in the differential diagnosis by determing VOCs in the headspace of acute mononuclear leukemia cells(SHI-1). Methods The air samples from the headspace of SHI-1, Human macrophages cells and medium control were collected by syringes, and then determined by means of solid phase microextraction-gas chromatography/mass spectrometry ( SPME-GC/MS ) in order to have a better under-standing of the concentration distributions and changes of VOCs in SHI-1 cells' headspace. Results Using Mann-Whitney U test, we found that eight kinds of VOCs were different among them. They were 2,4-dimethyl heptanes, 4-methyl octane, chloroform, benzene, 3,7-dimethyl dodecanese, hexanol, cyclohexanol, cetane. And alkane, benzene were significantly higher than the control group ( P<0.05 ) , alcohol decreased significantly ( P<0.05 ) . Conclusion SHI-1 cells have an impact on the concentration distributions of VOCs in their headspace. The most outstanding VOCs are alkanes, alcohol and benzene compared with the blank control group. They may be potential markers characteristic of leukemia cells.
ABSTRACT
Volatile organic compounds (VOCs) are organic chemicals which can exist in the form of vapor at room temperature.Endogenous VOCs can be produced by different biochemical processes in the human body.They can be transfered to lung through bloodstream and released through breath.Many researches show that exhaled VOCs can be significantly changed when people suffering cancers or inflammation. Detecting exhaled VOCs through instrument with high sensitivity make it possible to detect cancers in early phase in a noninvasive and rapid way,which reduce the suffering of patients.In conclusion,exhaled VOCs detection is a promising method for early diagnosis of cancers.
