Objective To evaluate the effects of propofol and thiopontal on calcium and potassium channels in rat ventricular myocytes and to elucidate the underlying mechanisms of their inhibitory effect on myocardium. Methods Freshly isolated ventricular myocytes were prepared from hearts of rats by trypsin. The effects of propofol and thiopental on L-type calcium current(Ica) and delayed rectifier potassium current(IK)were compared using whole-cell patch clump technique. Results Propofol and thiopontal produced a concentration-dependent inhibition of Ica. Peak concentration of propofol(50 ?mol?L~(-1)) and thiopental(100 ?mol?L~(-1)) during induction of anesthesia decreased Ica by 28% and 46% and shifted the steady-state inactivation curve to more negative voltage, but had no effect on the steady-state activation curve. Propofol and thiopental also decreased IK in a concentration-dependent manner, but the effects of both anesthetics on IK were smaller compared with their effects on Ica. Conclusion The findings of this study suggest that the negative inotropic of propofol and thiopental are, at least in part, related to decrease in Ca~(2+) trans-sarcolemmal current by accelerating L-type calcium channel inactivation. Both anesthetics decrease delayed rectifier potassium current, thus partially antagonizing the effect of decreased calcium current.

Objective:To study the cytotoxic effects on tumor cell lines Hela,BGC823,MCF-7,L342,H9101,D6 induced by Fas ligand and anti-human DR5 monoclonal antibodies(Anti-DR5 mAb) and the underlying mechanism.Methods:Fas/DR5 mRNA were detected by RT-PCR. Cytotoxicity exerted by FasL/Anti-DR5 mAb on tumor cell lines was measured by MTT colorimetry and the induced apoptosis was determined by agarose gel electrophoresis.Results:The expression of DR5 on BGC823 and Hela cells were higher and DR5 didn’t express in D6. The expression of Fas on H9101 and L342 were higher and Fas didn’t express in D6. Cell line H9101 and L342 were sensitive to Anti-DR5 mAb and FasL in a dose dependent manner; Cell line MCF-7 and BGC823 were sensitive to FasL but were partially sensitive to Anti-DR5 mAb; Cell line Hela was partially sensitive to FasL but was sensitive to Anti-DR5 mAb; Cell line D6 was insensitive to two apoptosis inductions.Conclusion:Apoptosis induced by Fas ligand and Anti-DR5 mAb vary among tumor cell lines. The underlying mechanism may be relevant to Fas/DR5 mRNA expression,the release of Caspase-8 and Bcl-2.

Purpose To investigate the effects of different concentration of ketamine on Ca2 transsarcolemmalinflux induced by KCl in isolated rat ventricular myocytes. Methods Freshly isolated rat ventricular nyoeyteswere loaded with Fluo-3AM, a Ca2 + indicator. The effects of different concentration ketamine( 1 × 10- s, 1 × 10- 4,1 × 10-3 mmol/L) on the change of intracellular Ca2+ concentration induced by KCl were investigated. ResultsLow concentration ketamine(1 × 10-5 mrnol/L) did not change Ca2+ transsarcolemmal influx. Although mediumeoncentration ketamine( 1 × 10-4 rmol/L) made the influx slower, the eventual peak concentration of intracellularCa2+ had no difference from that of the control group. The high concentration ketamine (1 × 10-3 mmol/L) inhibited Ca2-1 influx,intracellular Ca2+ fluorescent intensity decreased about 13.2% (P＜0.05). ConclusionsKetamine inhibits Ca2 + trranssarcolemmal influx in isolated rat ventricular myocytes dosedependently, which may inpart explain its negative inotropic effect.

Objective:To evaluate the clinical effects of ball attachment and Locator attachment for implant-supported overdenture.Methods:67 cases with edentulous jaw were treated with 150 Straumann and Bego implants and implant-supported overdentures using ball attachments Locator attachments,respectively.All cases were followed up regularly,biological and mechanical complications were observed,the patient satisfaction after restoration was compared between groups.Statistical analysis was performed using SPSS 17.0 software.Results:Follow-up was completed in 58 cases,25 with ball attachment,26 with Locator attachment and 7 with ball changed by Locator.Biological complications comparison showed that the incidence of gingival hyperplasia in the ball group was higher than that in the Locator group(P ＜ 0.05).There was no statistical difference of mechanical complications between the 2 groups (P ＞ 0.05),but the incidence of all kinds of mechanical complications in the Locator group was less than those in the ball group,the average repair frequency of the ball and Locator group was 1.9 times and 0.9 times respectively.Patients'satisfaction on chewing and retention was higher in the Locator attachment group than that in the ball attachment group(P ＜ 0.05).No statistical difference was found in patients' satisfaction between genders (P＞0.05),and no correlation of satisfaction was found with patients' age and follow-up time.Conclusion:The clinical effects of implant-supported overdenture using the Locator attachment is superior to that using the ball attachment.

AIM To elucidate the direct effects of propofol and thiopental on cardiac contraction by measuring intracellular Ca 2+ concentration change in cultured rat ventricular myocytes. METHOD Ventricular myocytes of neonatal rats were obtained by enzymatic digestion with typsin and were cultured for 4～5 days, then were loaded with Fluo 3AM, a new Ca 2+ indicator. The effects of propofol (50, 250 ?mol?L -1 ) or thiopental (100, 500 ?mol?L -1 ) on changes of intracellular Ca 2+ fluorescent intensity induced by KCl, isoprenaline or caffeine were investigated. RESULTS Both intravenous anesthetics caused dose dependent inhibit Ca 2+ transsarcolemmal influx induced by KCl and isoprenaline, peak Ca 2+ fluorescent intensity decreased. The inhibitory effect of thiopental was more than propofol at equiopotency. Neither anesthetics altered the amount of Ca 2+ release from intracellular stores in response to caffeine. CONCLUSION The negative inotropic effects of propofol and thiopental, at least in part, may be mediated by a decrease Ca 2+ transsarcolemmal influx though voltage gated and receptor gated calcium channel, but it is not relate to sarcoplasmic reticulum Ca 2+ release.

OBJECTIVE: The purpose of this study is to assess the effects of aging on air-conducted sound elicited cervical vestibular evoked myogenic potential (cVEMP) and ocular vestibular evoked myogenic potential(oVEMP) in normal people. METHOD: Sixty normal subjects were recruited for the vestibular evoked myogenic potential examination. Among them, 20-40 year-old group was setted as the first group, 41-60 year-old group was setted as the second group, > 60-year-old group was setted as the third group. Each group included 20 normal subjects. SPSS 16.0 software was used to analyze the data. RESULT: As the age growing, P1 latency prolonged, N1-P1 amplitude decreased, and amplitude asymmetric ratio increased in cVEMP; N1 latency prolonged, P1-N1 amplitude decreased, and amplitude asymmetric ratio increased in oVEMP. CONCLUSION With the age growing, the time of otolithic organ input pathways prolonged, the function of otolithic organ decreased and the decrease level may be asymeetrical on both sides.

Objective To explore the diagnostic value of whole?body bone scan combined with SPECT/CT imaging for osteofibrous dysplasia( OFD) . Methods A total of 30 patients ( 14 males, 16 fe?males, age range 10-48 ( average age 29.2) years) with OFD confirmed by pathology from June 2007 to De?cember 2014 were included. The images of whole?body bone scan and SPECT/CT imaging were retrospec?tively analyzed. Results Nineteen patients (63.3%, 19/30) showed monostotic OFD, which mainly in?volved extremities (n=18), especially the femur. Eleven patients(36.7%, 11/30) showed polyostotic OFD, which frequently be seen unilaterally (n=7). Highly or obviously abnormal uptakes of radiotracer were shown in most lesions (95.3%, 81/85) on whole?body bone planar images, the ribs and extremities showed abnormal uptake along the backbone orientation, while the cranium, pelvis and spine showed irregu?lar bulky uptake of radioactivity. On SPECT/CT images, the lesions of high or obvious abnormal uptake of radiotracer mainly showed cystic expansion growth, ground glass, vegetable sponge and mixed appearance;and the higher the radioactive aggregation degree was, the more the morphological changes were. The density and morphological changes on CT were not obvious for lesions with moderately and mildly abnormal uptake of radiotracer. Conclusion The whole?body bone scan combined with SPECT/CT imaging is an effective diag?nostic method for OFD.
