Objective:To investigate the clinical significance of bone metabolism indexes and human leukocyte antigen B27 (HLA-B27)in ankylosing spondylitis(AS)and analyze their diagnostic value. Methods:The subjects were 94 cases of AS patients,239 cases with other diseases and 80 healthy controls, and the results were retrospectively surveyed. Results:In the AS group, the concentration of the β-collagen specific sequence (β-CTX ) was higher ( P<0. 05 ) while the concentrations of osteocalcin ( OC ) , 25-hydroxyvitamin D[25-(OH)D] and parathyroid hormone(PTH)were lower than those in the control group. In the AS group,there was a positive correlation between the concentration of C-reactive protein(CRP)and β-CTX(P<0. 01),and the concentration of CRP was negatively correlated with the concentration of 25-(OH)D(P<0. 05). However,the concentrations of other bone metabolic indexes had no correlation with the concentration of CRP(P<0. 05). The positive rate of HLA-B27 in the AS group was significantly higher than that in other groups(P<0. 05),and HLA-B27 had highly sensitive and specific in the diagnosis of AS. In the AS group,the sensitivity of the concentration of 25-( OH) D was higher than β-CTX,while its specificity was lower than β-CTX. Conclusion:Bone metabolic indexes have great value in early screening and clinical diagnosis of AS,especially β-CTX and 25-( OH) D were more obvious.

In order to explore the role of real-time PCR in detecting minimal residual disease in multiple myeloma and Waldenstrom's macroglobulinemia after autologous peripheral blood stem cell transplantation (APBSCT), real-time PCR was used to quantitate the IgH rearrangement in 8 patients with multiple myeloma (MM) and 1 case of Waldenstrom's macroglobulinemia before and after APBSCT. The results showed that the copies of IgH rearrangement pre- or post-APBSCT were 3108 +/- 1043 and 549 +/- 660 (P < 0.05) respectively. The number of IgH copies was positively correlated with the amount of plasmocytes in patient 's bone marrow and the M-protein in peripheral blood (r = 0.86, P < 0.05). Similar result was obtained in a case of relapsed Waldenstrom's macroglobulinemia. In conclusion, the quantitative analysis of IgH rearrangement by real-time PCR is a novel way to evaluate the therapeutic efficaciousness and predict the prognoses in MM patients.

Objective: To explore the occurrence of cognitive impairment in Chinese heart failure (HF) patients and it's impact on prognosis. Methods: In this prospective observational study, a total of 990 HF patients were enrolled from 24 hospitals in China during December 2012 to November 2014. All patients were administrated with the interview-format Montreal Cognitive Assessment (MoCA), according to which they were divided into MoCA<26 (with cognitive impairment) group and MoCA≥26 (without cognitive impairment) group. Baseline data were collected and a 1-year follow up was carried out. Univariate and multivariate logistic or Cox regression were performed for 1-year outcomes. Results: Cognitive impairment was evidenced in 628 patients (63.4%) and they were more likely to be older, female, and with higher proportion of New York Heart Association(NYHA) class Ⅲ-Ⅳ, chronic obstructive pulmonary disease (COPD), ischemic heart disease, while body mass index (BMI), education level, and medical insurance rate were lower (all P<0.05) as compared to patients in MoCA≥26 group. The rate of percutaneous intervention, device implantation, cardiac surgery and evidence-based medications were significantly lower in MoCA<26 group than in MoCA≥26 group (all P<0.05). During the 1-year follow up, patients in the MoCA<26 group had higher all-cause mortality (10.2%(64/628) vs. 2.2%(8/362), P<0.01), cardiovascular mortality (5.9%(37/628) vs. 0.8%(3/362), P<0.01) and major adverse cardiac and cerebrovascular events (MACCE) (9.6%(60/628) vs. 2.5%(8/362), P<0.01) than patients in the MoCA≥26 group. In univariate regression, MoCA<26 was associated with increased all-cause mortality (HR(95%CI):4.739(2.272-9.885), P<0.01), cardiovascular mortality (HR(95%CI):7.258(2.237-23.548), P=0.001) and MACCE (OR(95%CI):4.143(2.031-8.453), P<0.01). After adjustment by multivariate regression, MoCA<26 was indicated as an independent risk factor for all-cause mortality (HR(95%CI): 6.387(2.533-16.104), P<0.01), cardiovascular mortality (HR(95%CI): 10.848(2.586-45.506), P=0.001) and MACCE (OR(95%CI): 4.081(1.299-12.816), P=0.016), while not for re-hospitalization for HF (OR(95%CI):1.010(0.700-1.457), P=0.957). Conclusions: Cognitive impairment is common in HF patients,and it is an independent prognostic factor for 1-year outcomes. Routine cognitive function assessment and active intervention are thus recommended for HF patients.

Objective This study aimed to clarify the intervention effect of salidroside(SAL)on lung injury caused by PM2.5 in mice and illuminate the function of SIRT1-PGC-1ɑ axis. Methods Specific pathogen-free(SPF)grade male C57BL/6 mice were randomly assigned to the following groups:control group,SAL group,PM2.5 group,SAL+PM2.5 group.On the first day,SAL was given by gavage,and on the second day,PM2.5 suspension was given by intratracheal instillation.The whole experiment consist of a total of 10 cycles,lasting 20 days.At the end of treatment,blood samples and lung tissues were collected and analyzed.Observation of pathological changes in lung tissue using inverted microscopy and transmission electron microscopy.The expression of inflammatory,antioxidants,apoptosis,and SIRT1-PGC-1ɑ proteins were detected by Western blotting. Results Exposure to PM2.5 leads to obvious morphological and pathologica changes in the lung of mice.PM2.5 caused a decline in levels of antioxidant-related enzymes and protein expressions of HO-1,Nrf2,SOD2,SIRT1 and PGC-1ɑ,and an increase in the protein expressions of IL-6,IL-1β,Bax,caspase-9 and cleaved caspase-3.However,SAL reversed the aforementioned changes caused by PM2.5 by activating the SIRT1-PGC-1α pathway. Conclusion SAL can activate SIRT1-PGC-1ɑ to ameliorate PM2.5-induced lung injury.
