Objective To investigate the correlation between augmentation index (AI) of the radial artery and diastolic heart function in patients with hypertension.Methods Echocardiographs were obtained for 305 patients with hypertension.AI,pulse wave velocity (PWV) of peripheral arteries and serum pro-brain natriuretic peptide (proBNP) levels were determined.Correlations and receiver operating characteristic (ROC) curves were drawn between AI values and impaired diastolic function.Results AI levels were significantly increased in patients with impaired diastolic function diagnosed by ultrasound.Assessment of diastolic heart function based on proBNP levels revealed that AI and aortic pulse wave velocity were significantly elevated in patients with impaired diastolic function.The operating curve indicated that AI may be a more accurate and efficient index for the evaluation of impaired diastolic function compared to pWV.Correlation analysis also showed that proBNP levels had altered in parallel with changes in AI and PWV.After adjusting for various factors including age,gender,blood pressure and blood lipid,a positive correlation was observed between proBNP and AI with a correlation coefficient of 0.3697 (P =0.003).However,no correlation between proBNP and aortic PWV was seen after adjustment.Conclusions Changes in radial AI levels may reflect parallel changes in diastolic cardiac function in patients with hypertension,suggesting that AI may be utilized as a non-invasive clinical indicator of diastolic heart function.

Objective To investigate the application value of combined detection of serum human epididymis protein 4 (HE4),cancer antigen 125 (CA125) and cancer antigen 19-9 (CA 19-9) in early endometrial carcinoma.Methods Two hundred and six patients with early endometrial carcinoma (endometrial carcinoma group) and 118 patients with uterine fibroids (uterine fibroids group) were selected.Serum level of HE4 was measured by enzyme linked immunosorbent assay (ELISA),and serum levels of CA 125 and CA 19-9 were measured by chemiluminescence immunoassay(CLIA).The positive rates of serum HE4,CA125 and CA19-9 in the 2 groups were compared.The changes between pre-and post-operative in the serum levels of serum HE4,CA125 and CA19-9 were compared in 147 endometrial carcinoma patients.Results The serum levels of HE4 and CA19-9 in endometrial carcinoma group were significantly higher than those in uterine fibroids group [76.57 (56.92-104.60) pmol/L vs.56.75 (48.33-68.91) pmol/L,13.26(6.07-25.90) kU/L vs.7.64(3.76-16.45) kU/L],there were statistical differences (P =0.000),there was no statistical difference in serum level of CA125 between the 2 groups (P=0.106).In endometrial carcinoma group,the positive rates of serum HE4 and HE4 + CA125 + CA19-9 were significantly higher than the positive rates of serum CA125,CA19-9,CA125+CA19-9,there were statistical differences (P ＜ 0.01).The positive rates of serum HE4,CA19-9,HE4 +CA125,HE4 +CA19-9 and HE4 +CA125 +CA19-9 in endometrial carcinoma group were significantly higher than those in uterine fibroids group,there were statistical differences (P ＜ 0.01).The serum levels of HE4,CA125 and CA19-9 in post-operative in 147 endometrial carcinoma patients were significantly lower than those in pre-operative,there were statistical differences (P ＜ 0.01).Conclusion The diagnostic value of serum HE4 in early endometrial carcinoma is better than CA125 and CA19-9,while combined detection of serum HE4,CA125 and CA19-9 can raise the positive rate and be helpful for therapeutic effect evaluation.

Objective To study the curative effect and the prognostic factors of endoscopic traumatic optic neuropathy (TON). Methods The clinical data of 53 patients with TON from 2010 to 2015 years was retrospectively analyzed. Divided the patients into the surgery group and the non-surgery group, according to whether or not accept the treatment of endoscopic optic decompression. And evaluating the potential prognostic factors in chi-square test, group t-test and multiple regression analysis. Results In 53 patients (55 eyes ), 31 eyes have no visual acuity before treated: 8 eyes’ visual acuity was improved in 16 eyes (8/16) that accepted operation; 3 eyes’ visual acuity was improved in 15 eyes (3/15) that with non-operation;24 eyes have visual acuity before treated:11 eyes’ visual acuity was improved in 14 eyes (11/14) that accepted operation;3 eyes’ visual acuity was improved in 10 eyes (3/10) that with non-operation;19 eyes’ visual acuity was improved in 30 eyes (19/30) that accepted operation, the total effective rate was 63.3%, and there was no complications happened in the patients who accepted operation. The age, eye-side, sex, visual acuity, optic canal fracture , orbit fracture , all these factors have no correlation to the prognosis (P>0.05), but the interval time between injury and operation (less than 3 days) and the way of the treatment are benefit to improve vision (P<0.05). Conclusions The endoscopic optic decompression is an effective treatment in TON, and it’s better to improve vision in 3-day after TON.

Acquired chromosomal translocations can be identified in nearly 50% of human acute myeloid leukemias. The common chromosomal translocation in this disease is t(8;21) (q22;q22). It involves the aml1 (runx1) gene on chromosome 21 and the eto (mtg8, runx1t1) gene on chromosome 8 generating the aml1/eto fusion gene. An initial model for its pathogenesis emphasized the conversion of a hematopoietic transcriptional activator AML1 into a leukemogenic repressor which blocked myeloid differentiation at the level of target gene regulation. Aml1/eto fusion genes inhibit key hematopoietic transcription factor that function as tumor suppressors at several nodal point during hematopoietic differentiation. A new model is presented in which aml1/eto coordinates expansion of the stem cell compartment with diminished lineage commitment and with genome instability. In this review, the molecular role of aml1/eto fusion gene and his transcribed isoforms in regulating stem renewal, blocking hematopoietic differentiation and interacting with various lineage-specific transcription factors are summarized.

OBJECTIVE To investigate the effect of subcutaneousimmunotherapy(SCIT) on levels of the serum human beta defensin-2 in children with allergic rhinitis. METHODS 30 cases of children with allergic rhinitis who were treated by SIT were selected as the treatment group, 20 cases of healthy children as the control group. Serum HBD-2 concentration of the control group was tested. Serum HBD-2 concentration of the treatment group was tested at three different time points: before SCIT, half a year after SCIT and one year after SCIT. And total nasal symptom scores(TNSS) and medication scores were recorded at each time point. RESULTS The serum HBD-2 concentration of the control group, that of the treatment group before SIT, half a year after SIT and one year after SIT were 4.62[4.08; 4.87], 3.74[3.37; 4.61], 4.62[4.13; 5.54], 4.79[4.45;6.19]ng/ml. The HBD-2 concentration gradually increased after SCIT. The TNSS of the treatment group before SCIT, half a year after SCIT and one year after SCIT were 7.43±2.15, 4.17±2.16, 4.20±1.92, The medication scores of the treatment group before SCIT, half a year after SCIT and one year after SCIT were 1.25[0.75; 1.38], 0.25[0; 0.75, 0.25[0; 0.75].There was no correlation (all P>0.05) between the serum HBD-2 concentration and TNSS or medication scores of the treatment group. CONCLUSION The serum levels of HBD-2 in patients with allergic rhinitis were lower than those in normal persons. The specific immunotherapy raised the serum HBD-2 levels of allergic rhinitis patients.

The efficacy and safety of uric-acid-lowering therapy (UALT) on slowing the progression of chronic kidney disease (CKD) accompanied by hyperuricemia were assessed. We searched Cochrane Library, PubMed, EMbase, CNKI, Wanfang and Vip databases up to November 15, 2012 for randomized controlled trials (RCTs) which compared the effect of UALT to control therapy in hyperuricemic patients secondary to CKD, and then performed quality evaluation and meta-analysis on the included studies. Seven RCTs involving 451 cases were included. UALT delayed the increase of serum creatinine (MD=-62.55 μmol/L, 95% CI: -98.10 to -26.99) and blood urea nitrogen (MD= -6.15 mmol/L, 95% CI: -8.17 to -4.13) as well as the decrease of glomerular filtration rate [MD=5.65 mL/(min·1.73 m2), 95% CI: 1.88 to 9.41], decreased systolic blood pressure (SBP) (MD= -6.08 mmHg, 95% CI: -11.67 to -0.49), and reduced the risk of the renal disease progression (RR=0.30, 95% CI: 0.19 to 0.46). However, there was no statistically significant difference in 24-h urinary protein quantity and diastolic blood pressure (P>0.05). We identified that UALT could delay the progression of CKD with secondary hyperuricemia. And this also indirectly proved that hyperuricemia was a risk factor for the CKD progression.

Objective To investigate the relationship among Helicobacter pylori(H.pylori),CD4 positive cells and CD8 positive cells in gastric mucosa of the AIDS patients with gastritis.Methods Fiftyeight AIDS patients with upper abdominal pain were diagnosed with chronic gastritis through gastroscopy.The gastric biopsies from them were used for H.pylori detection with rapid urease test and Giemsa staining,pathology examination with HE staining,and immunohistochemistry analysis for CD4,CD8 positive cells in Gastric mucosa.And the application of flow cytometry was for the detection of peripheral blood CD4 and CD8 lymphocytes from the patients.Results H.pylori was positive in 26 cases,and negative was in 32 cases.CD8 cell expression in gastric mucosa of the AIDS patients with H.pylori positive was significantly higher than H.pylori negative patients(P＜0.05).There is no difference CD4 cell expression in gastric mucosa between the AIDS patients with H.pylori positive and H.pylori negative patients.Moreover,CD8 positive lymphocytes in gastric mucosa of those patients with H.pyloriinfection were significantly stronger than the CD4 positive lymphocytes.However,the peripheral blood CD4 lymphocytes from the patients with H.pylori infection were more than those from H.pylorinegative patients significantly(P＜0.05).Conclusion The expression level of CD8 cells in gastric mucosal tissues of AIDS patients with H.pylori infection were higher than those without H.pylori infection.The CD4 lymphocytes from the peripheral blood of the patients with H.pylori infection were more than those without H.pylori negative patients.

OBJECTIVETo investigate the proportion of Th17 cells in the peripheral blood of the patients with acute myeloid leukemia (AML) and evaluate the potential association of Th17 cells with AML.

METHODSThe cytokines IL-17 and TGF-β1 in the peripheral blood of AML patients before therapy (group 1), AML patients in complete remission (AML-CR, group 2) and healthy donors (group 3) were measured by enzyme-linked immunosorbent assay (ELISA). The proportion of Th17 cells of each group was evaluated by flow cytometry. The level of IL-17 mRNA of each group was examined by reverse transcription-PCR (RT-PCR).

RESULTSThe percentage of Th17 cells and the level of IL-17, IL-17 mRNA in group 1 \[(10.502 ± 1.071) ng/L, (0.935 ± 0.140)% and 0.262 ± 0.510\] and group 2 \[(11.345 ± 0.987) ng/L, (1.091 ± 0.159)% and 0.307 ± 0.031\] was significantly lower than that in group 3 \[(16.852 ± 1.198) ng/L, (2.586 ± 0.235)% and 0.501 ± 0.060\]. The percentage of Th17 cells and the level of IL-17, IL-17 mRNA in group 1 was lower than that in the group 2. But the level of TGF-β1 in the group 1 (29.963 ± 1.588) ng/L and the group 2 (25.163 ± 1.848) ng/L was significantly higher than that in group 3 (13.366 ± 1.565) ng/L. However, the level of TGF-β1 in the group 3 was higher than that of the group 2.

CONCLUSIONTh17 cells might be negatively correlated with the AML development. The overexpression of TGF-β1 in AML patients might suppress the differentiation of Th17 cells.
