Objectives: To assess the feasibility and stability of right ventricular outflow tract (ROVT) pacing under current technology by comparing the results of ROVT pacing with the traditional right ventricular apex (RVA) pacing. Methods: A total of 42 patients (at mean age of 63.5±10.4 years) without structural heart disease were randomly divided into two groups. RVA pacing group (n=14),and RVOT pacing group(n=28). An active fixation lead was implanted in all patients whose pacemaker could automatically measure the pacing threshold every day. The operation time,X-ray exposure time and lead parameters detected during the operation were collected to evaluate the feasibility of RVOT pacing. The complications related to lead and implantation procedure and the trend of threshold change during the follow-up time were used to assess the stability of RVOT pacing.Results: There were no statistic differences between RVA pacing group and RVOT pacing group in terms of operation time,X-ray exposure time and lead parameters. In RVOT group,the change of threshold during acute period was similar to those in RVA group (P=0.23). Chronic pacing threshold was also comparable between two groups,mean threshold at 6 months follow-up time was 0.55±0.11V and 0.54±0.09V at 0.4 pulse width in RVA group and RVOT group respectively (P=0.787).Conclusion: RVOT pacing was feasible and stable in operation time and lead characteristics compared with the conventional RVA pacing under current pacing technology.

The neurofilament proteins (NFPs) from different neuronal tissues including Alzheimer and Huntington disease gray matter, rat brain gray, white matter and spinal cord were separated biochemically into two major fractions. A systematic investigation on the distribution, expression and phosphorylation of NFPs in those fractions was undertaken in the present study. It was found that only non-phosphorylated NF-H and NF-M, but not NF-L subunit were detected in Alzheimer brain gray matter high speed supernatant, whereas all neurofilament subunits including non-phosphorylated and phosphorylated were measured in high speed pellet fraction of the same tissue. The hyperphosphorylation of NF-H and NF-M in Alzheimer brain was shown by phosphorylation dependent monoclonal antibodies SMI31 and SMI34. This hyperphosphorylation was confirmed by non-phosphorylation dependent antibody SMI32 with dephosphosphorylation of the samples. Furthermore, an increased amount of NF-H, NH-M and NF-L, detected by SMI33 and NR4 respectively, was also observed in Alzheimer samples, in which the elevation in NF-L was significant. A significantly different immunoblot patterns in distribution, expression and phosphorylation were determined in various position of the neural system and alternative fractions. To our best knowledge, this is the first data shown definite abnormality of NFPs in Alzheimer disease. The information obtained in the present study will be extremely valuable in further study of the proteins both in physiological and pathological conditions.

Primary liver cancer has the features of high malignancy, rapid progression, frequent recurrence/metastasis, and high mortality, and therefore, most patients have developed intrahepatic or extrahepatic metastasis when attending the hospital and thus lost the opportunity for surgical treatment. Chimeric antigen receptor T-cell (CAR-T) immunotherapy has achieved good efficacy in the treatment of B-cell acute lymphoblastic leukemia, and clinical trials have been initiated to explore its applications in solid tumors such as primary liver cancer, pancreatic cancer, gastric cancer, and prostate cancer. This article reviews the efficacy of CAR-T immunotherapy in the clinical trials for primary liver cancer and discusses the difficult issues that need to be solved in clinical practice, such as the lack of suitable tumor targets, the inhibitory effect of tumor microenvironment on CAR-T cells, and the poor infiltration of CAR-T cells in tumor tissue, so as to provide a reference for related clinical studies.
