Objective To evaluate the clinical outcomes of sirolimus-eluting stenting in patients with coronary artery disease and type 2 diabetes.Methods Among 101 patients with coronary artery disease and type 2 diabetes who underwent percutaneous coronary intervention, 67 received sirolimus-eluting stents (SES group) and 34 were treated only with bare metal stents (BMS group). Baseline clinical characteristics, procedural success rate, occurrence of cardiac events during follow-up were recorded and compared between the two groups. Results The procedural success rate was 100% in both groups. During follow-up(average one year), the SES group patients had significantly lower occurrence of cardiac events than those in the BMS group ( 7.5% vs. 32.4%, P= 0.001).Conclusions Sirolimus-eluting stent implantation for patients with coronary artery disease and type 2 diabetes is safe and can reduce major adverse cardiac events in long-term follow-up.

OBJECTIVE:To improve rational drug use and reduce potentially inappropriate medication (PIM). METHODS:PIM of 700 elderly inpatients in internal medicine department of our hospital was evaluated by Beers criteria(2012 edition)and STOPP/START criteria. RESULTS:700 inpatients whose mean ages were (76.3 ± 7.2) years old took (12.1 ± 4.9) kinds of drugs per patient. 144 cases involved PIM(20.6%). The number of PIM was 220 in total,among which there were 117 cases/times relat-ed to drugs and 22 cases/times related to disease in according to Beers criteria,9 cases/times of STOPP and 72 cases/times of START. Drug with most frequency of PIM in accordance with Beers was benzodiazepines and most frequency in STOPP was thia-zides that used by patients with gout histonry. The most omission frequency of START prescription were absence of metformin thera-py for type 2 diabetes and absence of antiplatelet therapy for diabetes complicated with cardiovascular risk. CONCLUSIONS:A high prevalence of PIM in elderly inpatients in our hospital requires various measures to prevent its occurrence.

Sequences analysis revealed Grass carp reovirus (GCRV) s10 was 909 nucleotides coding a 34 kDa protein denoted as VP7, which was determined to be a viral outer capsid protein (OCP). To obtain expressed OCP in vitro, a full length VP7 gene was produced by RT-PCR amplification, and the amplified fragment was cloned into T7 promoted prokaryotic expression vector pRSET. The recombinant plasmid,which was named as pR/GCRV-VP7,was then transformed into E.coli BL21 host cells. The data indicated that the expressed recombinant was in frame with the N-terminal fusion peptide. The over-expressed fusion protein was produced by inducing with IPTG, and its molecular weight was about 37kDa, which was consistent with its predicted size. In addition, the fusion protein was produced in the form of the inclusion body with their yield remaining steady at more than 60% of total bacterial protein. Moreover,the expressed protein was able to bind immunologically to anti-his-tag monoclonal antibody (mouse) and anti-GCRV serum (rabbit). This work provides a research basis for further structure and function studies of GCRV during entry into cells.

Objective To observe the expression of Glu、mGluR 5 and EAAT 1 in bone tissues of ovariectomized osteoporotic rats and the effects of Total Flavonoids of Rhizoma Drynariae (TFRD) on it. Methods 45 SPF 3-month-old Sprague-Dawley (SD) female rats were randomly divided into sham operation (Sham, n=15) group and ovariectomized (OVX, n=30) group. The osteoporotic(OP) model was established by bilateral ovariectomy, 14 weeks later, we measured bone mineral density(BMD) by dual-energy X-ray and determined that OP model was successfully replicated, OVX group rats were then divided into OVX group (n=15) and OVX+TFRD group (n=15). The OVX+TFRD group was given TFRD for 12 weeks. Glutamate (Glu), metabotropic glutamate receptor 5 (mGluR 5), and Glutamate/Aspartate Transporter (GLAST/EAAT 1)’s expression of femur was examined in order to clarify the characteristics of bone glutamate signaling pathway and the effects of TFRD on it. Results Glu and ionotropic receptors mGluR 5 mainly distributed in bone marrow cells and osteoblasts closed to the bone marrow cavity walls. There were no significant differences in Glu expression among Sham group, OVX group and OVX+TFRD group. The mGluR 5 expression of OVX+TFRD group was significantly higher than that of Sham group and OVX group(P=0.009), while no significant difference was found between the latter two groups. In addition to large distribution in bone marrow cells, small amount of transporter EAAT 1 was noted to express in bone cells of the bone lacunae. There were no significant differences in EAAT 1 expression among the three groups. Conclusion In bone glutamate signaling pathway, this study demonstrated that TFRD could significantly improve the ionotropic receptor mGluR 5’s expression, but had no inlfuence for Glu and EAAT 1.
