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 compare different regimens of intraperitoneal injection of cyclophosphamide (CTX) to establish a rabbit model of premature ovarian failure (POF), and provide a useful experimental tool for further research of premature ovarian failure. Methods A total of twenty-one 5-6 months old rabbits were randomly divided into 4 groups. The group A (normal control group) included 3 rabbits without any treatment. The group B (the first model group) included 6 rabbits, received a single intraperitoneal injection of 50 mg/kg cyclophosphamide. Six rabbits in the group C (the second model group) were injected with 50 mg/kg cyclophosphamide once daily for 2 days. The group D (the third model group, also n=6) was injected with 50 mg/kg cyclophosphamide on the first day and then followed by 8 mg/ (kg·d) injection q.d. in the 14 consecutive days. Body weight and ovary weight of the rabbits in each group were measured, and the changes of body weight and the ovary index were analyzed. Morphological changes of the ovarian follicles were observed by HE staining and the numbers of normal and abnormal follicles at different developmental stages were counted and analyzed. Cell apoptosis was analyzed by TUNEL staining and changes in the serum levels of estradiol (E2) were detected by ELISA. Results The body weight of rabbits in both groups B and group C was not significantly changed during the experimental period (P> 0. 05). Rabbits in the group D showed a slight growth (P < 0. 05) and high mortality. The ovary index in group C was significantly lower than that in the group A (P < 0. 05). The ratios of abnormal primordial and primary follicles in groups B and C were significantly increased (P < 0. 017), and the ratio of abnormal primordial follicles in the group C was increased more significantly (P < 0. 017). However, there was no significant difference in the ratios of abnormal primary follicles between groups B and C (P> 0. 017). Among the groups A, B and C, there was no significant difference in the ratios of abnormal secondary and antral follicles (P> 0. 05). Apoptosis mainly occurred in granulosa cells of the ovarian follicles. The apoptosis rate of groups B and C was significantly higher than that in the group A (P < 0. 05), and the apoptosis rate of group C was higher than that in the group B (P < 0. 05). In the group B, the serum E2 level reached the peak value on the 7th day, significantly higher than that on the 35th day (P < 0. 05), and then the level was decreased gradually. In the group C, the E2 level was continuously decreased and the level on the last day before drug injection was significantly higher than that at the 35th day (P < 0. 05). Conclusions Intraperitoneal injection of 50 mg/kg cyclophosphamide once daily for 2 days is a most suitable method for the establishment of rabbit model of premature ovarian failure (POF).

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.
