Objective To investigate the effect of phosphoinositide-3-kinase inhibitor LY294002 on the differentiation of human embryonic stem cells (HESC) into more mature insulin-producing cells. Methods HESCs were induced to differentiate into insulin-producing cells through five stages. Nicotinamide and B27 (group B27), nicotinamide and LY294002 (group LY) were used to induce the nesting positive cells into mature insulin-producing cells. The morphological change of each stage was observed under microscope , and expressions of insulin, c-peptide, somatostatin and glucagon were identified by immunofluorescence staining. Results After 14 days in stage 5 , there was no significant difference in rate of insulin positive cells between group LY and group B27 (P﹥0.05), but rates of somatostatin and glucagon positive cells in group LY were lower than those in group B27(P﹤0.05). Furthermore, the co-stained rate of somatostatin and insulin in group LY was also lower than that in group B27 (P﹤0.05). Conclusion HESCs can be induced to differentiate into more mature insulin-producing cells by phosphoinositide-3-kinase inhibitor LY294002 in serum-free culture medium.

Objective:To evaluate the efficacy of continuous infusion of lidocaine via urinary catheter for postoperative analgesia in patients undergoing urological surgery.Methods:Forty male American Society of Anesthesiologists physical status Ⅱ or Ⅲ patients, aged 65-75 yr, with body mass index of 18-25 kg/m 2, scheduled for elective percutaneous nephrolithotomy, were divided into 2 groups ( n=20 each) using a random number table method: continuous infusion of lidocaine through urinary catheter group (group L) and patient controlled intravenous analgesia (PCIA) group (group PCIA). All the patients underwent total intravenous anesthesia, and a matched type of sterile urethral irrigation catheter was inserted after the operation.In group L, 0.5% lidocaine was continuously infused at a rate of 5 ml/h via the urinary catheter, while the equal volume of 0.9% normal saline was continuously infused via the urinary catheter, and PCIA was connected in group PCIA.PCIA solution contained sufentanil 125 μg (diluted to 250 ml in normal saline), and the PCA pump was set up with a 5 ml bolus dose, a 15 min lockout interval and background infusion at a rate of 5 ml/h.When visual analogue score was>4, sufentanil 0.05 μg/kg was injected intravenously as rescue analgesic.The development and severity of catheter-related bladder discomfort (CRBD) were recorded immediately at the end of the operation (T 1), and at 6 h (T 2), 24 h (T 3) and 48 h (T 4) after the operation, respectively.Riker sedation-agitation scale (SAS) score was recorded at T 1, 2, and QoR-9 scale was recorded at T 3, 4.The concentrations of serum cortisol (Cor), norepinephrine (NE), epinephrine (E) and blood glucose (Glu) were measured by enzyme linked immunosorbent assay.First off-bed time, exhaust time, length of hospital stay after surgery, and the requirement for rescue analgesia and adverse reactions (nausea and vomiting, respiratory depression, hypotension, skin itching) within 48 h after the operation were recorded. Results:Compared with group PCIA, the incidence of CRBD and the severity were significantly decreased at T 1-4, SAS score was decreased at T 1, 2, QoR-9 score was increased at T 3, 4, Cor, NE, E and Glu concentrations were decreased at T 1-4, the incidence of postoperative rescue analgesia was decreased, first off-bed time, exhaust time and length of hospital stay after surgery was shortened, and the incidence of postoperative nausea and vomiting, respiratory depression, hypotension, skin itching was decreased in group L ( P<0.05). Conclusion:Continuous infusion of lidocaine through the urinary catheter can provide good postoperative analgesia, reduce postoperative stress response and adverse reactions, and facilitate early postoperative recovery in patients undergoing urological surgery.

Objective The aim of this study was to evaluate the safety and efficacy of 135 cm Corsair microcatheter inpercutaneous coronary intervention (PCI) for coronary chronic total occlusion (CTO) with antegrade approach via radial artery. Methods From June 2010 to February 2014, a total of 81 patients with CTO lesions treated with 135cm Corsair microcatheter (Asahi Intec Co, Japan) and transradial antegrade approach was enrolled in this study. The success rate of CTO-PCI, the rate of Corsair microcatheter crossing the CTO lesions and the number of balloon catheters utilization were retrospectively analyzed. Unique complications related to the Corsair microcatheter were also documented. Results Success recanalization of CTO were achieved in 73 (90.1%) patients. Crossing the CTO body with Corsair microcatheter was found in 56(84.8%) patients. The number of balloon utilized after Corsair microcatheter crossing the CTO was much lower than that of patients who Corsair microcatheter failed to cross (1.3±0.6 per patient versus 2.8±1.2per patient, P < 0.05). The success recanalization rate of combined using Fielder XT guidewire with Corsair microcatheter was 51.5%. There was no complications related to Corsair microcatheter during the index procedure, no major adverse cardiac events during in-hospital clinical follow-up. Conclusions Corsair microcatheter was safe and effective in the recanalization for CTO with transradialantegrade approach. It can simplify the CTO-PCI procedure and reduce the number of balloon catheters.

Objective:
To investigate the safety and efficacy of rotational atherectomy in the interventional treatment of coronary chronic total occlusion lesions.
Methods:
In this retrospective study,a total of 31 consecutive patients with coronary chronic total occlusion(CTO) lesions underwent rotational atherectomy in our hospital from February 2004 to December 2016 were enrolled,and the clinical features were analyzed. Coronary atherectomy was performed if balloon failed to cross the CTO lesions or balloon could not be fully dilated in the CTO lesions after wire crossing. The definition of procedure success was defined as residual stenosis less than 20% after implantation of drug eluting stent and rotational atherectomy. After the procedure, the patients were followed up to observe major adverse cardiac and cerebral vascular events which including cardiogenic death, myocardial infarction, cerebrovascular accident, and target lesion revascularization.
Results:
The 1.25 mm diameter burr was firstly selected in 80.6% (25/31) patients,and 96.8%(30/31) patients used only 1 burr to complete the rotational atherectomy procedure. The complication rate was 9.8% (3/31) including 1 patient with coronary dissection and 3 patients with slow flow or no flow. There was 1 patent with both coronary dissection and slow flow. The procedure success rate was 96.8%(30/31). Interventional treatment related myocardial infarction occurred in 3 patients during hospitalization.The 30 patients with procedure success were followed up 36(11, 96) months. The incidence rate of major adverse cardiac and cerebral vascular events was 13.3% (4/30), of which the cardiogenic death rate was 3.3% (1/30), the myocardial infarction rate was 6.7% (2/30), cerebrovascular accident rate was 3.3%(1/30),and the target lesion revascularization rate was 6.7% (2/30).
Conclusion
