BACKGROUND: Theoretically, a novel single-sided groove target release biodegradable stent can avoid drug-induced inflammation of the local vessel wall, reduce drug dose, decrease the likelihood of thrombosis, and relieve stenosis.OBJECTIVE: To evaluate the influence of the novel single-sided groove target release biodegradable stent on intimal hyperplasia in a healthy porcine coronary artery model.METHODS: Eighteen healthy pigs were randomly divided into three groups, bare metal stent group, Firebird metal stent group and Firehawk stent group, which were implanted with L605 cobalt chromium alloy bare metal stents and L605 cobalt chromium alloy non-biodegradable rapamycin-eluting stent and L605 cobalt chromium alloy biodegradable rapamycin-eluting stent, respectively. Two same stents were implanted into the left anterior descending artery and the right coronary artery of each pig, respectively. After 1 and 3 months of follow-up, coronary angiography was performed,and the pigs were killed to take coronary artery samples for detection of intima hyperplasia.RESULTS AND CONCLUSION: At 1 and 3 months after stent implantation, no stenosis, thrombosis and aneurysm occurred in the three groups shown by the coronary angiography; the lumen loss was significantly lower in the Firebird metal stent group and Firehawk stent group than the bare metal stent group (P < 0.05), while there was no difference between the Firebird metal stent group and Firehawk stent group. Histopatologically, there was no coronary arterial tissue necrosis or luminal thrombosis in the three groups. Compared with the bare metal stent group, at 1 and 3 months after stent implantation, the neointimal area and the percentage of stenosis were significantly lower in the Firebird metal stent group and Firehawk stent group (P < 0.05), while the residual lumen area and internal elastic lamina area were significantly higher (P < 0.05). Additionally, there was no significant difference between the Firebird metal stent group and Firehawk stent group. Overall, the Firehawk stent that achieves the same clinical efficacy as the non-biodegradable rapamycin-eluting stent effectively inhibits intimal hyperplasia, and prevents stent restenosis after stent implantation.However, future investigations on the long-term effect are warranted.

Parkinson's disease (PD) is one of the most frequent neurodegenerative disorders. ?-Synuclein was the first"PD gene"to be discovered. The involvement of ?-synuclein in PD was first suspected after two different ?-synuclein mutations were identified in two kindreds with autosomal-dominant PD. However,the discovery that ?-synuclein is the major component of Lewy bodies-pathological hallmarks of PD, confirmed its role in PD pathogenesis. Pathological aggregation of ?-synuclein might be responsible for neurodegeneration. Multiple factors have been shown to affect ?-synuclein aggregation in vitro or in vivo. In addition, soluble oligomers of ?-synuclein might be even more toxic than the insoluble fibrils found in degenerative diseases. So it is significant to investigate factors affecting ?-synuclein aggregation, especially their accurate effects on the aggregation process.

OBJECTIVE:An LC-MS method was developed for the determination of thioctic acid in human plasma.MET-HODS:The chromatographic separation was carried out on Zorbax SB C18 column with the mobile phase consisting of methanol-acetonitrile-0.1% glacial acetic acid(adjusted pH to 4.0 with ammonia)(55∶10∶35) at a flow rate of 0.3mL?min-1.Naproxen was used as internal standard.Column temperature was 40℃.SIM was used for determination of thioctic acid in human plasma.Ion mass spectral(m/z) of 205.0 was selected for thioctic acid and 229.3 for naproxen.RESULTS:The linear range of thioctic acid was 0.01～10?g?mL-1(r=0.999 9).The method recovery was within 97.61%～106.31%.The intra-day and inter-day RSD of thioctic acid(high,medium and low concentrations) were all less than 4%.CONCLUSION:The method is sensitive,accurate and reproducible,and suitable for the determination of thioctic acid in human plasma and its pharmacokinetic and bioavailability study.

Objective To observe the clinical efficacy of acupuncture-moxibustion in treating urinary retention after anorectal operation.Method Forty patients with urinary retention after anorectal operation were randomly allocated to a treatment group and a control group, 20 cases each. The treatment group was intervened by acupuncture -moxibustion, and the control group by oral administration of Pyridostigmine bromide tablets. For the two groups, 10 d treatments were taken as a course. Two treatment courses later, the residual urine volume and spontaneous micturition were measured to see the changes, and the clinical efficacies were also compared. Result The total effective rate was 90.0% in the treatment group versus 70.0% in the control group, and the between-group difference was statistically significant (P<0.05). The residual urine volume was significantly changed after the treatment in both groups (P<0.05). After the intervention, the residual urine volume in the treatment group was significantly different from that in the control group (P<0.05). After the treatment, the mean spontaneous micturition time was (16.52±3.18)min in the treatment group, versus (41.37±5.63)min in the control group, and the between-group difference was statistically significant (P<0.05).Conclusion Acupuncture-moxibustion is an effective approach in treating urinary retention after anorectal operation, since it can reduce the residual urine volume and shorten the spontaneous micturition duration.

Objective To investigate the role of the plan-do-check-action(PDCA) cycle in the quality management of intravenous infusion devices.Methods Based on the self-controlled design and cross-sectional study, the application of intravenous infusion devices before and after the implementation of PDCA cycle was investigated and compared, and the role of PDCA cycle in intravenous infusion device was evaluated.ResultsThe patients treated with intravenous infusion of 38 departments were investigated (1 152 cases in stage P and 1 140 cases in stage C).After the application of PDCA cycle,the accuracy rate of intravenous infusion device use increased from 93.2％ to 97.4％ (χ2=13.030, P<0.001).The accuracy rate of needle indwelling (98.6％ vs.95.7％, χ2=8.894, P=0.003) and central venous catheter use (87.5％ vs.38.9％, χ2=12.963, P<0.001) significantly increased after the application of PDCA cycle.Conclusion The PDCA cycle can remarkably improve the management quality of intravenous infusion devices.

Clinical studies show that the factors that impact the quality of life (QOL) in patients with lung cancer are comprehensive.Physiological factors include breathing difficulties,cancer-related fatigue.Depression,anxiety and other psychological factors also play a major role.Social and family support is also crucial to improve the QOL in patients with lung cancer.
