The Journal of Practical Medicine 2016;32(5):809-811
Objective To investigate the effects of Qiliqiangxin capsule on serum concentration of adiponectin (APN) and heart function in patients with uremia combined with heart failure. Methods Uremia patients combined with heart failure were randomly divided into treatment group and control group , both of which were given anti-failure routine therapy. The patients in treatment group were treated with Qiliqiangxin capsule for 8 weeks and those in control group with placebo. The New York Heart Association (NYHA) heart function classi-fication, left ventricular end-diastolic diameter (LVEDD), left ventricular end-systolic diameter (LVESD), left ventricular ejection fraction(LVEF), and the levels of APN were observed before and after treatment. Results The level of APN in uremic patients combined with heart failure was significantly higher than that in normal subjects. With the increase in the class of NYHA heart function, the serum concentrations of APN increased, but the difference was not significant(P > 0.05). After 8 weeks′ treatment, the effective rate in treatment group was higher than that in control group (P < 0.05). LVEDD and LVESD in both groups decreased significantly. LVEF in both groups increased, but serum concentration of APN decreased significantly. More obvious effects were observed in treatment group (P < 0.05). Conclution Qiliqiangxin capsule could significantly reduce the level of APN and improve heart function in patients with uremia combined with heart failure.

BACKGROUND: Research on seed cells is the most important aspect in the filed of tissue-engineering research, and because of their various ad vantages, bone marrow mesenchymal stem cells (BMSCs) have been taken as the ideal bone tissue-engineering seed cells. OBJECTIVE: To observes the growth characteristics of in vitro cultured BMSCs and their osteogenetic characteristics under non-inducing conditions. DESIGN: A single sample experiment.SETTING: Implanting Center of Stomatological Hospital of Fujian Medical University MATERIALS: This experiment was conducted at the Central Laboratory of Stomatological Hospital of Fujian Medical University, between May andDecember 2003. BMSCs are derived from the primary passage to the 3rd passage of in vitro cultured cells from 4 one-year old dogs. METHODS: Under the aseptic conditions, bone marrow puncture was made at bilateral femur trochanter and 5 mL of heparin anticoagulatedbone marrow was obtained. Then it was placed in 50 mL of anti-Dulbecco's modified Eagle's culture medium in centrifuge tube for monocyte isolation. The BMSCs single cells were primarily isolated and placed in culture box for subculture. After 48 hours, culture medium was removed and the medium was cha1ged once every 3 days. Then subculture was carried on continuously to observe BMSCs in morphology under inverted the phase contrast microscope with the assistance of HE staining. The number of cells was counted daily to calculate doubling time and to draw a growth curve. Alkaline phosphatase was detected by using calcium-cobalt method,and chinalizarin staining was used to detect the growth state of calcification tubercle. MAIN UTCOME MEASURES: ①Optical microscopic structure of dog BMSCs; ② The growth curve of dog BMSCs; ③Observation of osteogenetic index- alkaline phosphatase and calcification tubercle. RESULTS: ① Morphological observation indicated that BMSCs were adherent to the walls, clonogenic and appearing fibroblastic phenotype, and they presented morphological changes without exposing to osteogenetic inducer. ② The expression of Alkaline phosphatase in primary cells was stronger, and it was strong in the 1st passage cell, but weak in the 2nd and 3rd passage cells. ③Calcium deposition was observed, which was stronger in primary cells than in subcultured cells. CONCLUSION: ①BMSCs massively proliferated during in vitro culture,capable of differentiating into osteoblasts and considered as the optimal seed cells for bone tissue-engineering reconstruction. ② BMSCs derived from the 3rd passage has osteogenic activity, but the osteogenic activity of the primary cultured cells was stronger than thatr of the subcultured cells.

Objective: To study relationship among ambulatory pulse pressure (PP), pulse pressure index (PPI) and carotid intima-media thickness (IMT) in aged patients with hypertension. Methods: The 24h ambulatory blood pressures of 159 subjects were measured, and their ambulatory PP [(mean systolic blood pressure (SBP) - mean diastolic blood pressure (DBP)] and ambulatory PPI (ambulatory PP/mean SBP) were calculated. Color Doppler ultrasonography was used to measure carotid IMT. Relationship between ambulatory PPI and carotid IMT was analyzed. Results: Pearson correlation analysis indicated that carotid IMT was correlated with age (r=0.353), mean SBP (r=0.594), mean DBP (r=-0.355), ambulatory PP (r=0.855) and ambulatory PPI (r=0.883), P<0.001 all. Multivariant gradual regressive analysis indicated that carotid IMT possessed significant linear correlation with ambulatory PP and ambulatory PPI (R2=0.789), and standardized regression coefficient β of ambulatory PPI (β=0.621) was higher than that of ambulatory PP (β=0.284). Conclusion: Ambulatory pulse pressure index and ambulatory pulse pressure are good indicators for evaluation of carotid arteriosclerosis, and value of ambulatory pulse pressure index is more than.

Objective To investigate the value of urine L-type fatty acid-binding protein (uL-FABP) and uric neutrophil gelatinase-associated lipocalin (uNGAL), and predict the value of poor outcomes (injury progression,dialysis,or death within 7 days ) in critically ill patients with early acute kidney injury (AKI) at time of nephropathy consultation. Methods One hundred and twenty-five patients with evidence of the AKIN criteria stage1 AKI were enrolled in this study. At time of nephropathy consultation , urinary samples were collected. The levels of uL-FABP and uNGAL were measured. Each marker was assessed for its predictive value using an area under the receiver operator characteristic curves (ROC-AUC) to predict AKI prognosis. Results Twenty-eight patients developed poor outcome. It was 0.81 in ROC-AUC in uL-FABP , in,which it could be improved to 0.83 when combined with APACHEⅡscore (0.75 in ROC-AUC). The ROC-AUC of uNGAL was 0.66, in which it could not impove its predictive power significantly when combined with APACHEⅡscore. Conclusion Among critically ill patients with early AKI , uL-FABP provided an independent and prognostic power when combined with APACHEⅡscore and the level of uL-FABP at time of nephropathy consultation helps to predict clinical outcome in critically ill patients with early AKI.

Background and purpose:Radiotherapy and endocrine therapy are both important parts of adjuvant therapy for breast cancer, yet few studies have been conducted focusing on the interaction between radiation and endocrine therapy. Up to now, no conclusion has been drawn on the timing sequence of adjuvant radiation and endocrine therapy, which is indeed crucial in clinical practice. This study intended primarily to investigate the effect of concurrent or sequential exemestane combined with radiation on radiosensitivity of MCF-7 cells and its possible mechanism,and further to provide rationale for optimal clinical treatment modality.Methods:MCF-7 cells were arranged into three trial groups: the radiation group, exemestane sequenced with radiation group and exemestane followed radiation group. Radiosensitivity was evaluated by clonogenic assay, cell proliferation was measured by MTT assay, the ability to induce cell apoptosis was evaluated by DAPI staining assay, the changes of Bcl-2 and Bax were detected by Western blot.Results:Sensitive enhancement ratios (SER) were 1.51 and 1.37 in the exemestane sequenced with radiation group and exemestane followed radiation group, respectively. Compared with the radiation group, the percentage of cellular proliferation inhibition and apoptosis increased obviously in the exemestane sequenced with radiation group and exemestane followed radiation group. Exemestane combined with radiation made the Bax protein increase obviously and the Bcl-2 protein lowered significantly.Conclusion:Exemestane can enhance the radiosensitivity of MCF-7 cells, whose mechanism might be relevant to the promotion of cellular apoptosis. However,the treatment sequence does not affect the outcome.
