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.

Objective To test the reliability and validity of Chinese version of Stressful Life Events Questionnaire and the influence of preinjury stressful life events on the life quality and mood symptoms of the patents following cerebral concussion.Methods 285 patients with cerebral concussion were assessed by Stressful Life Events Questionnaire(SLESQ),PTSD Checklist civilian version(PCL-C),Thirty-Six-Item Short-Form Health Survey (SF-36),Hamilton Depression Rating Scale(HDRS),Hamilton Anxiety Scale(HAMA) at baseline.The patients had been reassessed with the HDRS,HAMA,SF-36 at 3 months after cerebral concussion.The hierarchical regression analyses were used to determine the influence of Stressful Life Events for the life quality and mood symptoms of the patient with cerebral concussion.Results The incidence of stressful life events was 42.8％.The multiple regression analysis showed the experience of stressful life events were the influence factor of scores on the SF-36,HDRS,HAMA after adjusted by the age,gender,education,income,social support,the scores of anxiety and depression before injury and the R 2 value of SLESQ to SF-36 physical health factor,mental health factor,HDRS,HAMA was 0.064,0.111,0.145,0.028,respectively.Conclusion The history of stressful events is the influence factor of the patient with cerebral concussion to have poor life quality and mood disorder.

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.

ObjectiveTo investigate the value of CEUS in differential diagnosis of benign and malignant thyroid solid lesions.MethodsTotally 45 patients with thyroid solid lesions underwent CEUS examination.The enhancement mode and blood perfusion characteristics of malignant and benign lesions were analyzed,and the results were compared with pathology.ResultsCEUS diagnosed 31 benign lesions and 14 malignant masses.The diagnostic accordance rate of CEUS was 93.75％ (30/32) and 92.31％ (12/13) for benign and malignant lesions respectively.In 31 benign lesions,27 (27/31,87.10 ％) showed entire homogeneous enhancement,4 (4/31,12.90％) presented inhomogeneous enhancement.In 14 malignant masses,1 (1/14,7.14 ％) showed homogeneous hypoechoic enhancement,12 (12/14,85.71％) presented inhomogeneous hyperechoic enhancement and 1 (1/14,7.14％) presented non-enhancement.ConclusionCombined with two-dimensional grey scale ultrasound and CDFI,CEUS enables dynamic observation of the microvascular perfusion of thyroid lesions,therefore helps to differentiate benign and malignant thyroid lesions.

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.
