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 analyze plasma vitamin E and CoQ10 levels in patients with autosomal recessive cerebellar ataxia for finding the evidence of the related pathogenesis research and therapeutic strategies.Methods The plasma vitamin E and CoQ10 levels were detected by high performance liquid chromatography (HPLC) with diode array detector in 123 probands of autosomal recessive cerebellar ataxia pedigrees.Quantitation was performed using vitamin E and CoQ10 external standard and two 5-point calibration curve;clinical manifestations were analyzed simuhaneously.Results Vitamin E and CoQ10 levels of healthy subjects in the plasma were (8.77 ± 2.28) μg/ml and (1.31 ± 0.38) μg/ml,respectively;the plasma vitamin E and CoQ10 levels of patients were (5.61 ± 2.04) μg/ml and (0.79 ± 0.26) μg/ml,respectively,which were significantly lower than those in healthy controls (t =11.87,13.15;all P＜ 0.01).Clinical manifestations were characterized by cerebellar symptoms,and gait instability was usually the first recognized abnormality.Most of early onset occurred before the age of 25 years (111/123);dysarthria and abnormal eye movement were observed,with cerebellar atrophy on MRI;concomitant symptoms were also present.Conclusions HPLC analysis shows that the plasma vitamin E and CoQ10 levels of patients with autosomal recessive cerebellar ataxia are generally lower than those in the healthy controls.Several patients with significant reductions in these two levels have genetic defects.The combination of clinical phenotypes,biochemical indexes and genetic analyses will be helpful for the establishment of diagnosis and specific treatment.

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.

Objective To discuss the effect of melatonin on sleep and agitation in patients who had undergone tracheotomy in ICU.Methods Sixty-six tracheotomisd patients of ASA Ⅱ or Ⅲ in ICU were included,age 18-60 years,weaning from mechanical ventilation not receiving continuous sedation.We conducted a double-blind, placebo-controlled randomized pilot study comparing melatonin with placebo in such patients.They were allocated into two groups by compute randomiza-tion-melatonin group(n =32)and control group(n = 34).We administered either oral melatonin (3 mg)or placebo at 20∶00 for 7 days.We collected pre-and post-dosage blood samples on days 1 and 3 to confirm drug delivery.The hours of sleep at day and night were assessed by the bedside nurse as the primary outcome.And the secondary outcome included comparison of the incidence of agitation, assessed by score on the Riker Sedation Agitation Scale,and requirement for sedatives or haloperidol to settle agitation.Results Pre-treatment melatonin levels in the two groups were similarly low.Post-treatment,melatonin levels increased significantly in the melatonin group compared with the placebo group (3 233±1 961 )pg/ml versus (3.8 ± 2.2 )pg/ml(P < 0.05 ).And subsequently the observed sleep time in the two groups was (1 1.9±2.0)hours for melatonin vs (7.8±1.6)hours for placebo, respectively (P < 0.01 ).The incidence of agitation was significantly lower in the melatonin group (0% vs 8.8%).Conclusion Melatonin is well absorbed,and a standard dose increases blood levels approximately 1000-fold.Furthermore it would help the tracheotomisd patients sleep and ease agitation in ICU.

Background and Objective Large randomized controlled trials have demonstrated that percutaneous coronary intervention (PCI) with the routine use ofdrug-eluting stents is safe and effective, however, the patients older than 75 years undergoing PCI are at increased risk for major adverse cardiac events, so that the patients are usually excluded from this trial. The aim of the present study was to assess the early clinical outcome and risk factors in old patients with acute ST elevation myocardial infarction (STEMI) following primary PCI. Methods We analyzed the outcome after stenting in 136 patients older than 60 years in our coronary care unit with acute STEMI, and the patients were further classified in 2 age groups: patients≥75 years and <75 years. Results Though the older group had a higher prevalence of adverse baseline characteristics and lower final TIMI flow than those of the younger, the procedural success had no difference between two groups. The main adverse clinical events (MACE) for the old group was a little higher comparing with the younger in 12-month following up. Conclusions Our study suggest that drug-eluting stent implantation in elderly patients with acute ST elevation myocardial infarction has high initial procedural success rates despite having more severe baseline risk characteristics, and to shorten the time form symptom onset to PC1 and improve final TIMI flow strategy may decrease MACE among old patients following PCI.
