Objective To evaluate the curative effect and problems of X-ray fluoroscopy guided percutaneous vertebroplasty (PVP) in treating osteoporotic spinal compression fractures. Methods Twenty-four patients (15 females and 8 males) with 44 vertebral compression fractures underwent PVP. They were average 69 years of age (48-83 years). The fracture segment was within T 5-L 3 (20 thoracical vertebrae, 24 lumbar vertebrae). Under the guidance of C-arm fluoroscopy, bone marrow biopsy needle was inserted percutaneously via transpedicular way into the fractured vertebrae. Polymethylmethacrylate (PMMA) was then injected into the fractured vertebrae. Vasual analogue scale (VAS), mobility and analgesic usage were evaluated 2 days before and after PVP and in the follow-up period. Results PVP was successful in 21 cases (40 vertebrae ), but failed in 2 cases (4 vertebrae) due to weak position endurance. The volume of PMMA injected was 1.0-8.0 ml per vertebrae. The average follow-up period was 3.1 months (1-7 months). VAS was sharply decreased from pre-PVP 7.5?1.2 to 2.8?1.0 at day 2 after PVP (P

There is no a systemic performance metrics for clinical data management. While the CDMC in China starts to develop the quality metrics for clinical data management, it is essential to think over the performance and pursue metrics implementation of clinical data management in China. This article provides the basic concept, development and implementation of the performance metric in clinical data management.

Graphene/Room temperature ionic liquids ( GN/IL ) nanocomposite was prepared by grinding graphene and ionic liquid 1-butyl-3-methylimidazolium bromide ( BMIMPF6 ) which mixed together in appropriate proportion. Atomic force microscopy ( AFM ) was utilized to characterize the formation of the GN-ILs. Due to the synergistic effect between ionic liquids and graphene, the nanocomposite exhibited excellent performance toward H2 O2 reduction. A novel uric acid ( UA) electrochemical sensor was fabricated based on uricase-GN/IL modified glassy carbon electrode. The experimental results showed that the response displayed a good linear response toward UA in the concentration range from 0. 002-4. 5 mmol/L. The corre1ation coefficient was 0. 995 and the detection limit was 0. 85 μmol/L. The easily prepared electrochemical sensor had favorable stability and selectivity and could be applied to the quick determination of UA in human serum, thus providing a new UA detection method for clinical trial.

Objective To investigate the effects of different doses of dexmedetomidine on the minimum alveolar concentration of sevoflurane for blunting responses to skin incision ( MACBAR ) in patients undergoing lower abdominal surgery. Methods Sixty ASA Ⅰ or Ⅱ patients, aged 25-55 yr, weighing 45-75 kg, undergoing electire lower abdominal surgery under general anesthesia, were randomly divided into 4 groups ( n = 15 each): control group (Do group) and 3 dexmedetomidine groups (D1, D2 and D3 groups). The patients were unpremedicated.Dexmedetomidine was not used in group D0. A loading dose of dexmedetomidine 0.1μg/kg was injected iv over 10 min, and then dexmedetomidine was infused at a rate of 0.4, 0.8 and 1.2 μg· kg- 1 · h - 1 for 30 min in groups D1-3 respectively. Anesthesia was induced with inhalation of 8 % sevoflurane. Laryngeal mask airway was inserted when BIS value decreased to 45-55. The patients were mechanically ventilated with inhalation of sevoflurane and a mixture of 50% nitrous oxide and 50% oxygen, and the fresh gas flow was set at 1 L/min. In D0-3 groups, the initial end-tidal concentrations of sevoflurane were 3.0%, 2.5%, 2.0% and 1.5% respectively. The patients' response to skin incision was described as effective if MR or MAP increased by ＜ 15%, or ineffective (MR or MAP increased by ≥ 15%). When the response was effective, the end-tidal concentration of sevoflurane was decreased in the next patient, when ineffective, increased, and the ratio between the two successive concentrations was 0.9.The MRCBAR of sevoflurane was determined by up-and-down method, and 95% confidence interval was calculated.Results The MRCBAR (95% confidence interval) of sevoflurane was 2.85% (2.44%-3.32%), 1.91%(1.61%-2.26%), 1.52% (1.31%-1.77%), and 1.34% (1.15%-1.57%)in D0-3 groups respectively. The MRCBAR of sevoflurane was significantly lower in D1-3 groups than in D0 group, and in D2 and D3 groups than in group D1 (P ＜0.05＝. There was no significant difference in MRCBAR of sevoflurane between D2 and D3 groups (P ＞0.05) .ConclusionContinuous infusion of dexmedetomidine at 0.4, 0.8 and 1.2 μg·kg-1 ·h-1 for 30 min results in a decrease in MACBAR of sevoflurane and enhances the inhibitory effect of sevoflurane on the stress response, and in a dose-dependent manner.
