Objective\ To evaluate the efficacy of atrial lead implantation during atrial fibrillation.Methods\ In 10 patients(group A),the atrial leads were implanted during atrial fibrillation and the sensing and pacing parameters before and after restoring to sinus rhythm were compared with the parameters of patients whose atrial leads were implanted during sinus rhythm (group B).Results\ During follow-up,the sensing and pacing parameters were measured,and there were no significant difference between group A and B.In group A,mean atrial potential amplitude during atrial fibrillation was correlated with the telemetered atrial potential amplitude during sinus rhythm.Conclusion\ Atrial lead implantation during atrial fibrillation is feasible.

Alcohol consumption leads to injury in multiple organs and systems,including the liver,brain,heart,skeletal muscle,pancreas,bone,immune system,and endocrine system.Emerging evidence indicates that alcohol also promotes adipose tissue dysfunction,which may contribute to injury progression in other organs and systems.Autophagy is a lysosomal degradation pathway that has been shown to regulate adipose tissue homeostasis and adipogenesis.Increasing evidence also demonstrates that alcohol consumption affects autophagy in multiple tissues.This review summarizes current knowledge regarding the effect of autophagy on adipose tissue and its potential roles in alcohol-induced adipose tissue atrophy as well as its contribution to alcohol-induced liver injury.

Based on previous results of 16S rDNA sequence homologuous and results of physic-biochemical indexes and morphological characteristics in the present work, bacterial strain ge15 isolated from roots of ginseng plants was identified as Stenotrophomonas rhizophila. Confronting incubation results showed that, strain ge15 inhibited the growth of Alternaria panax, Phytophthora cactorum, and Cylindrocapon destructans significantly, and the width of inhibition zone was 13.3, 24.0, 12.0 mm, respectively. Further results showed that the emergence rate and seedling survive rate of ge15 treatment was significantly higher than those of the control, and which was similar to pesticide carbendazol treatment. The ge15 strain has good application potential in ginseng diseases control without contamination.

Objective To investigate the clinical allocation significance of modified early warning score (MEWS) for emergency department patients.Methods MEWS of 1 069 patients in medical emergency department from August 2011 to March 2013 were recorded and analyzed.The admitted differences of MEWS among in intensive care unit(ICU),general wards and emergency transfer observing patients were compared.Results The MEWS of emergency department patients were different.The deaths and ICU patients together as ICU patients,MEWS ≥ 7 scores the proportion of patients admitted to ICU were significantly higher than those of MEWS 3-6 scores and 0-2 scores [37.8％(14/38) vs.2.1％ (6/289) and 0.1％(1/742)](P＜0.01).Conclusion MEWS provides an objective allocation basis for emergency department patients.

Objective To investigate the best MR technique for detecting small epidermoids in the cerebellopontine angle.Methods 7 patients with pathologically-proved small epidermoids only located in the cerebellopontine angle were collected. The imaging techniques included:conventional T1WI and T2WI, fluid attenuated inversion recovery(FLAIR),diffusion weighted imaging(DWI) and balanced fast field echo(B-FFE) .The findings were retrospectively analyzed.Results 6 of 7 cases of epidermoid tumours localized at the cerebellopontine angle and exhibited the similar signal intensity as the cerebrospinal fluid(CSF) on T1WI and T2WI.The remaining case was slightly isointense on either T1WI or T2WI.On FLAIR images in 6 cases,3 cases showed slightly hyperintensity, 1 case showed doubtful heterogeneous signal intensity and 2 cases did not reveal any abnormal signal intensity.3 cases were hyperintense differenting from CSF on DW images. All of seven cases showed heterogeneous signal characteristics and were quite different from CFS on B-FFE.Meanwhile B-FFE also produced clearly the tissue contrast of trigeminus embedded in epidermoids of the cerebellopontine angle.Conclusion B-FFE is much more useful for the early diagnosis of epidermoids in the cerebellopontine angle and it also can provide precise preoperative information about the trigeminus encasement.

Objective To assess the feasibility and effectiveness of percutaneous transluminal angioplasty (PTA)for the salvage of immature arteriovenous fistula (AVF) and to identify the incidence of arterial and venous puncture site spasm.Methods The medical records and radiological data of 88 patients with 112 interventional procedures for immature AVFs were retrospectively reviewed.Results The stenosis lesions were (2.0 ± 1.4) cm long.Technical success rate and clinical success rate were 80.4％ (78/97) and 92.8％ (90/97) for PTA via brachial artery,85.7％ (6/7) and 100％ (7/7) for PTA via vein,25％ (2/8) and 50％ (4/8) for PTA via both brachial artery and vein,respectively.Spasm of pure arterial PTA occurred in 2 patients (2.1％) and was mild and moderate.Spasm of pure venous PTA occurred in 2 patients (28.6％) and was both moderate.Spasm of combined arterial and venous PTA occurred in 3 patients (37.5％) and from being severe to completely occluded.By comparison,there were statistical differences of technical and clinical success rate (P =0.000,0.019 ; P =0.000,0.029),fistulas spasm rate was statistically significant different (P =0.000).Conclusions Endovascular therapy was effective in restoring the dysfunctional native AVFs,it was safer and more effective and with less sideeffects especially in selecting coronary balloon to treat patients without large phlebangioma and round fistulas.

Objective To investigate the effects of allogenic intra-bone marrow bone marrow transplantation (IBM-BMT) on re-establishing hematopoiesis in mice. Methods Bone marrow mononuclear cells (BMNCs) from BALB/ c mice were transplanted into the C57BL/6 mice treated with a lethal dose of ~(60)Coγ-ray radiation through intra-bone marrow injection or intravenous injection. Sixty of the C57BL/6 mice were randomly divided into three groups as higher dose intra-bone marrow injection group (IBM1 group), lower dose intra-bone marrow injection group (IBM2 group) and intravenous injection group (IV group). The nucleated cell numbers of whole bone marrow from the tibia of each recipient mouse were counted respectively at the day 1, day 3, day 6 and day 9 after the transplantation. The donor-derived total nucleated cells and myeloid cells were quantified by flow cytometry. Results At 6th day after transplantation, more total bone marrow nucleated cells, total donor-derived nucleated cells and donor-derived myeloid cells in the tibia of injected side in both IBM1 group and IBM2 group were found than that in IV group (P<0.05 or P<0.01). Conclusion Compared with traditional bone marrow transplantation (IV-BMT),IBM-BMT improves the bone marrow hematopoiesis in the early hematopoietic re-establishing stage in allogenic bone marrow transplantation.
