RNA interference (RNAi), as a new technology of gene therapy, has been used in the studies of many diseases in vitro, however, targeting delivery of small interference RNA (siRNA) is still a bottleneck for clinical therapy of siRNA agents. Aptamer is a group of oligonucleotides with high affinity and targeting, and is becoming another important means of delivery for siRNA. In this review, we summarized siRNA delivery obstacles in vivo and recent attractive developments increatively using cell-internalizing aptamers to deliver siRNAs to target cells.

Objective To study the influence analysis of patients with anxiety and depression in elderly patients with hypertension antihypertensive effect of psychological intervention combined with Flupentixol and Melitracen Tablets.Methods 60 elderly patients with hypertension accompanied by anxiety and depression in our hospital from January 2014 to December 2016 were selected as the subjects.They were randomly divided into the control group and the experimental group, with 30 patients in each group.The control group was treated with conventional antihypertensive treatment, the experimental group were given psychological intervention combined with treatment of Flupentixol and Melitracen Tablets.The clinical indexes of the experimental group and the control group were compared and analyzed.Results After the corresponding treatment, the effective rate of antihypertensive treatment in the experimental group was 28 cases, and the effective rate of depressurization was 93.3%.The effective rate of antihypertensive treatment in the control group was 21, and the effective rate of antihypertensive treatment was 70%.After treatment, the HAMD score and HAMA score of the experimental group were significantly lower than those before the treatment, and the score of the experimental group was significantly lower than that of the control group, with statistical difference(P<0.05).Conclusion The treatment of elderly hypertensive patients with anxiety and depression in patients with better antihypertensive effect of psychological intervention combined with Flupentixol and Melitracen Tablets, can improve the depression and anxiety of patients in a large extent, high safety, is further applied in clinical significance.

Objective To test the accuracy of American College of Cardiology (ACC)/American Heart Association (AHA) guidelines for preoperative cardiovascular evaluation for noncardiac surgery in Chinese patients and to compare ACC/AHA guidelines with Goldman index and Lee index. Methods From January to December 2003, all patients aged ≥70 yr or patients aged 40-69 yr with a history of cardio- and cerebro-vascular disease, abnormal ECG or diabetes scheduled for noncardiovascular surgery were included in this study. A total of 1 248 patients were eligible. Their clinical data including demographic data, history of cardiovascular disease, routine physical examination and laboratory tests, the scheduled surgery and type of anesthesia were collected. The patients were then evaluated for cardiac risk and classified according to ACC/AHA guidelines (high, moderate, low and no risk), Lee index (class I -IV ) and Goldman index (class I - III ). The cardiac risk of the scheduled surgery was then stratified according to ACC/AHA guidelines. The patients were followed up until discharged from hospital. Cardiac events were defined as cardiac death, myocardial infarct, myocardial ischemia, minor myocardial cell injury, ventricular dysfunction and serious arrhythmia. Likelihood ratio of the 3 methods was calculated. Risk factors for adverse events were identified by univariate analysis and multivariate Logistic regression analysis. Results Of the 1 248 patients 694 were male and 554 female. Their age ranged from 40-102 years (mean age 65.4 yr). 44.7 % of the patients were aged ≥ 70 years. High risk operation accounted for 6.3 % and emergency operation 7.9% . One patients died of cardiac event and ten patients of other causes. Seventy-three perioperative cardiac events occurred in 53 patients. The morbidity rate was 4.2% . Goldman index and ACC/AHA cardiac risk stratification were correlated with adverse cardiac outcomes ( P

Objective To simulate the solution drought stress conditions with polyethylene glycol (PEG) 6000 for study on the seed germination of Cassia occidentalis.Methods The seed of C.occidentalis was treated with 5% and 10% PEG 6000,respectively,then the germination rate,the activity of superoxide dismutase (SOD),peroxidase (POD),and content of malondialdehyde (MDA) were measured.Results Compared with the same period of the control,soaking with 5% PEG 6000 for 5 h could increase the activity of SOD and POD,decrease the content of MDA.PEG Pretreatment could decrease free radical accumulation and make cell membrane system less damaged in the course of absorbing water in seed.Conclusion Soaking with 5% PEG 6000 for 5 h could increase the seed germination rate of C.occidentalis.

In the field of gene delivery, nonviral vectors are getting more attention due to the advantages which do not belong to viral vectors. But kinds of polypeptides are important to construct ideal nonviral vectors. The paper reviews the development in the research of polypeptides as components of nonviral vectors like as the backbone, the targeting moiety, the endosome membrane destabilizing agents and the nuclear localizing signals.
