Objective Right ventricular outflow tract septum has become widely used us an electrode placement site. However, data concerning lead performances and complications for lead repositioning with this technique were scant. The purpose of this study was to observe long-term lead performances and complications of right ventricular outflow tract septal pacing and provide evidences for choosing an optimal electrode implantation site. Methods Thirty-six patients with septal active electrode implantation and 39 with apical passive electrode implantation were enrolled in this study. Pacing threshold, R-wave sensing, lead impedance, pacing QRS width and pacing-related compli-cations for two groups at implantation and follow-up were compared. Results There were higher pacing threshold and shorter pacing QRS width at implantation in the septal group compared with the apical group. There were no differences between the septal and the apical groups in pacing threshold, R-wave sensitivity, lead impedance and pace-related complication during a follow-up. Conclusions Right ventricular outflow tract septum could be used as a first choice for implantation site because it had long-term stable lead performances and no serious complications compared with the traditional apical site.

According to the multi-information characteristic of pulse tracings in traditional Chinese medicine(TCM) and the dynamic analysis and identification technique of sonogram,the multi-information detection system of pulse examination was constructed by combining B-type ultrasound and flexible transducer.It made information integration of supersonic dynamic image,pressure pulse wave,photoelectric capacity pulse wave and electrocardiogram,and though the aggregate analysis of computer information processing technique,established the pulse tracings signature analysis method,formed optimized solving scheme for describing the four attributes("location,velocity,shape and potential") of pulse examination in TCM.From the multi-information data of healthy people's pulse tracings collected by this system,it can be infer that the new method of objectification of pulse examination referred in this article is feasible,and have gain the prospective effect.It provides a new method and characteristic data for the clinical study of objectification of pulse examination and teaching of TCM.

Objective To study the influence of valproate sodium(VPA)on neuroprotective effects of topiramate(TPM).Methods For-ty-eight 3-4 week-old male Wistar rats were randomly divided into 4 groups of 12 rats each.Group A was negative control rats,and groups B-D were rat model of epilepsy,induced by pentylenetetrazol(PTZ).The rats in 2 experimental groups were adminstered intragastrically with TPM 40 mg/kg and TPM 40 mg/kg+ VPA 200 mg/kg;2 control groups(groups A and B)with the equal amount of distilled water administration.After 2-month administration,changes of the behavior,levels of serum neuron-specific enolase(NSE)and the pathological in hippocampus were examined.Results The level of NSE in the group of TPM were significantly lower than that in masculine group,but no difference between masculine group and the TPM plus VPA.The pathological change in hippocampus were abatement in the group of TPM.Conclusion TPM plus high dosage of VPA will impaire the neuroprotective effects of TPM.

Objective Atrioventricular block (AVB) is a common and serious arrhythmia. At present, there is no perfect method of treatment for this kind of arrhythmia. The purpose of this study was to regenerate cardiac atrioventricular conduction by autologous transplantation of bone marrow mesenchymal stem cells (MSCs), and explore new methods for therapy of atrioventricular block. Methods Eleven Mongrel canines were randomized to MSCs transplantation (n=6) or control (n=5) group. The models of permanent and complete AVB in 11 canines were established by ablating His bundle with radiofrequency technique. At 4 weeks after AVB, bone marrow was aspirated from the iliac crest. MSCs were isolated and culture-expanded by means of gradient centrifugal and adherence to growth technique, and differentiated by 5-azacytidine in vitro. Differentiated MSCs (1ml, 1.5×107cells) labeled with BrdU were autotransplanted into His bundle area of canines by direct injection in the experimental group, and 1ml DMEM in the control group. At 1-12 weeks after operation,the effects of autologous MSCs transplantation on AVB models were evaluated by electrocardiogram, pathologic and immunohistochemical staining technique. Results Compared with the control group, there was a distinct improvement in atrioventricular conduction function in the experimental group. MSCs transplanted in His bundle were differentiated into analogous conduction system cells and endothelial cells in vivo, and established gap junction with host cardiomyocytes. Conclusions The committed-induced MSCs transplanted into His bundle area could differentiate into analogous conduction system cells and improve His conduction function in canine AVB models.

OBJECTIVETo observe interventional effects of anti-viral therapy and Compound Qin-gre Granule (CQG) on host cellular immune functions of acute virus infection patients.

METHODSThirty acute virus infection patients were recruited to detect peripheral lymphocyte subsets. They were randomly assigned to two groups, the Western medicine treatment group (treated with anti-virus Western medicine) and the integrative medicine treatment group (treated with anti-virus Western medicine plus CQG). T-cell subsets were re-examined 7 days later. Changes between before and after treatment were observed. Effect on host cellular immune functions and efficacy were compared between the Western medicine treatment and the integrative medicine treatment.

RESULTSCompared with the normal control group, the percentage of peripheral T cells increased, and the percentage of B/NK cells decreased in acute virus infection patients (P < 0.01). Meanwhile, in T cell subsets, the percentage of CD8+ T cells and CD8+ CD38+ T cells increased (P < 0.05, P < 0.01); and percentages of CD4+ T cells, CD4+ CD28 + T cells, and CD8+ CD28+ T cells decreased (P < 0.05, P < 0.01). After one-week treatment, percentages of CD4+ T cells, CD4+ CD28+ T cells, and CD8+ CD28+ T cells increased (P < 0.05, P < 0.01), while the percentage of CD8+ CD38+ T cells decreased (P < 0.01). More significantly, these changes were greater in the integrative medicine treatment group than in the Western medicine treatment group (P < 0.05).

CONCLUSIONSDisarranged cellular immune functions existed in acute virus infection patients. CQG could significantly improve viral infection induced immunologic derangement and immunologic injury.

Objective: To establish analytical method for the determination of vanadium ( V ), chromium ( Cr ), nickel ( Ni ), selenium ( Se ) and arsenic ( As ) in calcium based toothpastes by microwave digestion-inductively coupled plasma tandem mass spectrometry ( ICP-MS/MS ). Methods: The 21 calcium based toothpaste samples from supermarkets and shops in the urban areas of Hangzhou were digested by 6 mL HNO3 and 1 mL H2O2 in microwave digestion system. Then He-SQ mode and O2-MS/MS mode of ICP-MS/MS were respectively used for the determination of Ni and V, Cr, Se, As. Indium ( In ) was used as internal standard for calibration. Results: Good linear relationships were obtained for these five elements from 1.0 to 32.0 μg/L, with the correlation coefficients ranged from 0.999 3 to 1.000 0. The detection limits of the method ranged from 0.000 25 to 0.006 08 mg/kg. The recovery rates of standard spiking were 80.7%-105.7% when set at 0.4, 0.8 and 1.6 mg/kg, the recovery of standard reference material was 102.2%, and the relative standard deviations were 2.6%-4.8%. The concentrations of V, Cr, Ni, Se and As in 21 calcium based toothpaste samples were 0.024-1.935 mg/kg, 0.085-5.759 mg/kg, 0.090-3.673 mg/kg, <0.002 72-0.016 mg/kg and <0.006 08-0.321 mg/kg. Conclusion Microwave digestion-ICP-MS/MS can effectively reduce the interferences of polyatomic ions and doubly charged ions from the matrix, which is suitable for the determination of V, Cr, Ni, Se and As in calcium based toothpaste.

AIM: To investigate the affected proteins by tumor necrosis factor (TNF)-? in endothelial cells, and further explore the potential molecular mechanism of TNF-? on endothelial cells. METHODS: Nitric oxide (NO) production in the cultured human umbilical vein endothelial cells (HUVECs) was measured by a NO assay kit. Proteomic alterations were analyzed using two-dimensional electrophoresis, and peptide mass fingerprinting with matrix-assisted laser desorption/ionization-time of flight mass spectrometry. RESULTS: NO production in HUVECs decreased significantly after TNF-? treatement. Proteomics analysis showed 21 protein spots were changed including 9 spots that were increased and 11 spots that were decreased after TNF-? stimulation, and 1 spot was only detected in TNF-? activated cell gels. CONCLUSIONS: The decreased expression of ecNOS by TNF-? might result in decrease in NO production. Up-regulated MAP/ERK kinase 3 expression might imply that TNF-? activates the expression of adhesion molecules. Cytoskeletal protein actin is also involved in TNF-? injuried HUVECs. Proteomic analysis can find some clues for identifying new potential target of TNF-?. [
