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.

0.05).Conclusions There is imbalance of Th1/Th2 cells in CHB children.Th1 cytokines are positively correlated with hepatic inflammatory activity.In the course of disease,Th2 cytokines are predominant and they have a correlation to the chronic prognosis of the illness.So we can conclude the degree and prognosis of disease by observing the change of Th1/Th2 cytokines in CHB children.

OBJECTIVE To study the interaction of anthracene quinone type anti-tumor antibiotics and DNA as well as the experiment method.METHODS Spectrophotometry was developed including absorption spectrum,fluorescence spectrum,electrochemical method and so on.RESULTS The union of inlay and insertion observed in ultraviolet and visible spectrophotometry usually caused hypochromic effect and red shift.Under the certain concentrations of bovin serum albumin(BSA),the endogene fluorescence intensity of BSA orderly reduced with the increase in concentration of doxorubicin(adriamycin) hydrochloride(?em 344 and the peak shape were invariable);?ex and ?em at the biggest wave length of doxorubicin were 478 and 596 nm.The fluorescence intensity was maximal of the excitation and emission spectrum when pH was 3.0.CONCLUSIONS The interaction of doxorubicin and DNA is the strongest according to the experiment and is the most widely used at present in clinics.

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.

Both the sleep apnea scale of sleep disorders questionnaire (SA-SDQ) and the Epworth sleepiness scale (ESS) were used to evaluate 25 patients with snoring and 125 patients with obstructive sleep apnea hypoventilation syndrome ( OSAHS), and scores were calculated and compared to the results of polysomnography ( PSG). Results showed that there was significant difference in scores of ESS and SA-SDQ, apnea hyponea index (AHI) and the minimal saturation of blood oxygen (LSpO2) at night between patients with OSAHS and those with snoring (P ＜ 0.05). Score of both ESS and SA-SDQ significantly correlated with AHI ( r = 0. 78 and r = 0. 66, respectively, P ＜ 0. 01 ) , i. e. , more severe of the condition, higher the scores. Score of ESS is highly consistent with clinical presentations in patients with OSAHS and can be used as preliminary screening for its diagnosis, however, use of SA-SDQ score is limited in diagnosing OSAHS due to its lower consistency.

Objective To investigate the risk factors for sensorineural hearing loss (SNHL) in patients with nasopharyngeal carcinoma (NPC) after intensity-modulated radiotherapy (IMRT).Methods From January 2012 to January 2013,29 patients with histopathologically confirmed NPC who received radiotherapy alone or concurrent chemoradiotherapy were included in this study.All patients underwent hearing tests,including pure tone audiometry and acoustic immittance measurement,before and after the IMRT.The cochlear doses for each ear were also collected for analysis.A prospective analysis was performed to investigate the relationship between cochlear dose and SNHL in patients with NPC,and the effects of other factors,including time after radiotherapy,chemotherapy,T stage,and age,were also analyzed.Results Of the 58 ears studied,6(10％) had low-frequency SNHL,and 17 (29％) had highfrequency SNHL.There were significant differences in mean cochlear doses between the patients who developed SNHL after radiotherapy and those who did not (left ears:46.1 Gy vs.35.5 Gy,P =0.006;right ears:45.0 Gy vs.35.8 Gy,P =0.009).When the mean cochlear dose was less than 44 Gy,only 15％ (6/38) of ears had high-frequency SNHL.The invasion of skull base bone was also a significant risk factor for SNHL(P =0.047),but age,chemotherapy,and time after IMRT were not significant risk factors.Conclusions The mean cochlear dose and invasion of skull base bone are significant risk factors for SNHL in patients with NPC after radiotherapy.It is recommended that the mean cochlear dose should be limited to 44 Gy to minimize the incidence of SNHL after IMRT.

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 construct the adenovirus vector containing mice CD40- IgG2aFc-IRS-GFP fusion gene and detect the expression of the fusion protein in transfeete 293cells.Methods The fragments of CD40, IgG2aFc were obtained and inserted into plasmid PDC316-IgG2aFc-GFP.After being verified by sequencing, Ad5-PDC316-CD40-IgG2aFc-GFP was contransfored with the bckbone vector into 293 cells.The virus titer was detected after replicating and purifing and the expression of the fusion protein was analyzed.Results A virus and plasmid were constructed successfully.The vitro infection showed that the virus can infect cells of which the fusion protein was confirmed by fluo-rescence.The expression of the fusion protein increased with the increased time and virus concentra-tion.The protein expression stopped increasing after the virus concentration came to a certain level.Conclusion CD40, IgG2aFc fragments are correctly ligated with plasmid PDC316-IgG2aFc-GFP, and the fusion protein can be expressed in 293cells.This might lay a foundation for further studies of the expresstion of virus, immune tolerance and mechanism of liver transplantation model in rats.
