Envelope proteins of herpes simplex virus (HSV) plays a vital role not only in the infection process of adsorption and invasion but also in the stimulation to the organism that gives rise to immune response. Among the envelope proteins, glycoprotein D (gD), which can induce specific immune response, are the primary targets of humoral and cellular immunity of the host. In order to analyze the antigenicity and immunogenicity of HSV-gD1, we chemically synthesized the extracellular domain fragment gene of gD1, cloned it into eucaryotic expression vector pCEP4, and transfected the HEK293 cells with the recombinant vector. Then we identified the recombinant protein by Western blotting, and detected antigenicity of the protein by ELISA. Finally, we used the purified gD1 protein to immunize Kunming mice in 1, 3, 5 weeks, and collected antiserum in 3, 5 and 7 weeks. We titrated the sera for the detection of anti gD1 using an ELISA assay. Gene sequencing analysis demonstrated that the recombinant plasmid pCEP4-gD1 was constructed successfully. Western blotting analysis indicated one major protein band, which molecular weights is approximate 46 kDa corresponding to the truncated forms of gD1 protein, was observed. ELISA assay showed that the expressed recombinant protein gD1 had good antigenicity. After the third immunization, antibody titer of the mouse anti-gD1 was at least 5 x10(3). The successful expression of the recombinant protein gD1, which can induce humoral immune response, lays a foundation for serological diagnosis and vaccine study of HSV.

Objective To investigate the effectiveness and safety of drug-eluting stent implantation following rotational atherectomy (RA)for severe coronary arteries calcification in elderly patients. Methods A total of 21 patients receiving RA and drug-eluting stent implantation were enrolled in this study in our cardiology department from Sep.2014 to Sep.2017. Twenty-one patients with 27 severe calcified lesions were treated with the stent implantation following RA . The primary endpoints of the study were the immediate operation success rate and the rate of major adverse cardiac and cerebral events (MACCE)at 6 month after surgery ,including angina recurrence ,need for target vessel revascularization ,myocardial infarction ,stent thrombosis and cardiovascular death. Results 14 patients(66.7% ,14/21)received RA by using 1.5 mm burr ,and 7 patients(33.3% ,7/21)by using both 1.25 mm and 1.5 mm burrs. The average ratio of burr to artery diameter was (0.5 ± 0.1). A total of 29 stents were successfully implanted in all patients (100% ,21/21 patients).None of the patients experienced any acute coronary artery rupture or other severe complications during percutaneous coronary intervention (PCI ) after RA. Two cases (2/21 ,9.5% ) suffered from slow flow ,and the coronary blood flow was restored to TIMI grade Ⅲ after treatment. The coronary blood flow in the other 19 cases(19/21 ,90.4% )was TIMI grade Ⅲ after RA.Intravascular ultrasonography (IVUS) showed that the stents were well adhered without stent rupture and intimal tear in 12 cases(12/21 , 57.1% ) ,and postdilation was performed in 9 cases(9/21 ,42.9% ).All patients were followed up for at least 6 months ,and target vessel revascularization and death were not found. Conclusions A drug-eluting stent implantation following rotational atherectomy is effective and safe for treating severe coronary arteries calcification in elderly coronary heart disease patients. The IVUS-guided rotational atherectomy combined with drug-eluting stent implantation can reduce the risk of MACCE ,such as under-expansion stent ,stent thrombosis ,myocardial infarction ,cardiovascular death ,and improve clinical outcomes in elderly patients with severe coronary arteries calcification.

Objective To assess the effectiveness and safety of paclitaxel-coated balloons for in-stent restenosis in patients aged 65 years and over.Methods Sixty elderly patients(≥65 years old)with in-stent restenosis were enrolled at the Department of Cardiology,the First Affiliated Hospital of Inner Mongolian Medical University.Based on different treatment methods for in-stent restenosis,patients were divided into the drug-eluting balloon(DEB,n=32)group and the drug-eluting stent(DES,n=28)group.The primary end point was late luminal loss,determined by angiography.Secondary end points included rates of restenosis and major adverse cardiac events (MACEs).Results Quantitative coronary angiography revealed no significant differences in baseline data At 3 months after treatment,the rate of MACEs was 28.6％ in the DES group and 12.5％ in the DEB group(P＜0.05).At 6 months after treatment,angiography showed that the (x)±s of insegment late luminal loss was(0.21±0.04)mm in the DES group versus(0.12±0.06)mm in the DEB group(P ＜0.05).Furthermore,7 of 28 patients (25 ％) in the DES group had restenosis,compared with 4 of 32 patients (12.5 ％)in the DEB group(P =0.03).Conclusions Paclitaxel-coated balloons for coronary in-stent restenosis in patients aged 65 years or over can significantly reduce the incidence of restenosis and lower the rate of MACEs.The procedure is safe with no serious complications,eliminates the need for additional stent implantation,and should be further assessed in future clinical trials.

Objective To evaluate the clinical improvements after autologous bone marrow mononuclear cells (BMMNCs) percutaneously injected into coronary artery in patients with heart failure due to non-ischemic cardiomyopathy using PET myocardial peffusion/metabolic imaging.Methods From February 2011 to October 2012,40 patients with heart failure due to non-ischemic cardiomyopathy were selected.The test group including 15 patients (13 males,2 females,average age (57.5±14.5) years) received the autologous BMMNCs intracoronary injection on the basis of drug treatment.The other 25 cases (21 males,4 females,average age (58.0±12.0) years) were taken as the control group and only received the drug treatment.All patients were followed up for 24 months,and the myocardial perfusion/metabolism imaging,echocardiography,brain natriuretic peptide (BNP) test,6-minute walking experiment were performed.The data were analyzed by two-sample t test.Results During the follow-up period,the test group had no ventricular arrhythmia and other serious complications,and the patients' symptoms had been improved.There was no change in myocardial perfusion after treatment of autologous BMMNCs,but the myocardial metabolic defect by volume reduced from (43.79± 17.99) cm3 to (28.19±9.27) cm3 (t =3.33,P＜0.01) 24 months after the treatment.The myocardial metabolic defect by volume at the baseline and after 24 months in the control group was (43.30±15.70) cm3,(48.51±15.77) cm3 respectively (t=1.01,P＞0.05).In the test group,the left ventricular end-diastolic diameter decreased from (64.0±8.0) mm to (59.0±7.0) mm 24 months after the treatment (t=2.04,P＜0.05),and the left ventricular ejection fraction was significantly higher than that before treatment:(45.0±4.0) ％ vs (27.0±6.0) ％ (t =10.81,P＜0.01).Conclusion PET myocardial perfusion/metabolic imaging can be used as tools in evaluating the therapeutic effect of autologous BMMNCs in patients with heart failure due to non-ischemic cardiomyopathy.
