Objective To study anticardiolipin antibody(ACLA)in elderly patients with essential hypertension(EH)and to investigate the influence of valsarta on the function of vascular endothelium.Methods The levels of ACLA were measured by an enzyme-linked immunoabsorbent assay in 120 patients with EH and 30 healthy controls.All parameters were compared in the EH patients with different stratification.Sixty elderly hypertension patients were treated with valsarta for 6 weeks of with the dose range from 80 to 160 mg/d and compared with 60 healthy elderly people before and after treatment by measuring the levels of ACLA.Results The concentration of ACLA were significantly higher in patients with risk,higher risk and very high risk group than those in healthy control group and patients with low risk group(P0.05).After 6 weeks of treatment with valsarta,systolic and diastolic pressures remarkably decreased and the levels of ACLA were decreased significantly;the higher the degree,the more notable the change of ACLA.Conclusion The patients with EH might have self-immunity.The results suggest that circulating ACLA might have clinical significance in forecasting the severity of EH.Valsarta is effective in treating hypertension,which may improve the function of vascular endothelium.

Objective:To establish a green fluorescent protein(GFP)and firefly luciferase(Luc)double-labeled Epstein-Barr virus(EBV)infec-ted B lymphoblastoid cell lines(B-LCL)and apply them to mouse models,then compare the advantages and disadvantages of models inocu-lated by intravenous(IV)or subcutaneous(SC).Methods:B lymphoblastoid cell lines double-tagged with GFP/Luc(B-LCL-GL)were con-structed through lentivirus transduction,puromycin intervention.Subcutaneous xenograft and hematogenous metastasis models were re-spectively established by subcutaneous or intravenous injection of B-LCL-GL cells at three concentrations in(NOD)/Prkdcscid/IL-2Rγnull(NPG)mice for in vivo bioluminescence imaging.Results:In the B-LCL-GL group,the ratio of the GFP-positive cell population was 92.5%,and the average luminescence intensity was as high as 4.80E+08 Photons/s,which was considerably higher than that of untreated B-LCLs.In the hematogenous metastasis models,tumor bioluminescence was initially located in the peritoneal area and then spread throughout the en-tire body between 7 and 28 days.In the subcutaneous xenograft models,strong central and weak peripheral tumor-related biolumines-cence signal was detected on day 7 in the three groups,which then spread throughout the body on day 28 in the high-dose group.Taken to-gether,there was no significant difference in tumor progression between the two routes of administration when using the same dose of B-LCL-GL cells.However,the survival analysis indicated that the IV injection group,in which all the mice ultimately died,had a shorter time frame for testing than that of the SC injection group,in which the mice survived until day 100 in the low-dose and medium-dose groups,thus allowing for long-term testing.Conclusions:GFP and Luc dual-positive B-LCLs were successfully established to generate hematogenous metastasis and subcutaneous xenograft models,which allow the monitoring of the location and size of lymphomas in vivo.It provide plat-form for the study of tumor characteristics and selecting anti-tumor drugs.

Construction of smart hospitals is of great significance to the substantial development of medical institutions and the reform of medical and health systems and meanwhile it serves as a crucial support for the high-quality development of pub-lic hospitals.Guangdong Second Provincial General Hospital actively responds to national policies,constantly exploring standard-ized application of new smart medical technology.It has successfully built itself into a first full-scene smart hospital.Through gradually deepening the intelligent construction of hospitals,the hospital has achieved obvious achievements in hospital manage-ment such as medical services,medical resources,medical data,hospital operation logistics,and medical environment improve-ment.Their practical experience can provide references for the intelligent construction of hospitals domestically.
