OBJECTIVE: Radial artery hemostasis devices of TR Band and RDP made in Japan has used in China and abroad. However,comparisons of application effects are rarely reported. The aim of this paper is to investigate the safety and effectiveness of radial artery hemostasis devices of TR Band and RDP after transradial intervention procedures. METHODS: A total of 300 cases with transradial route coronary arteriongraphy and percutaneous coronary intervention, were randomly divided into 3 groups, with 100 cases in each group. TR Band, RDP, and "8" character Bandaging were used respectively. The hemostasis effectiveness, hemostasis time, patients' degree of comfort, disorder of venous return,saturation of blood oxygen of thrums of compressed hands, as well as ischemia and necrosis status in local skin of access site were compared.RESULTS: Two kinds of devices were able to hemostasis effectively. The saturation of blood oxygen of cases in each group was within normal limits, which had no significantly difference (P> 0.05). Patients' degree of comfort was significantly different among three groups (P< 0.05), but there was no insignificantly different between TR Band and RDP groups (P> 0.05).Swelling in arms and ischemia and necrosis status of local skin at access site were notably different among three groups (P <0.05), however, ischemia and necrosis status of local skin at access site had no difference between TR Band and RDP groups (P>0.05).CONCLUSION: Application of radial artery hemostasis devices of TR Band and RDP-700(800) after transradial intervention procedures is safe and effective.

65 years old) with in-stent restenosis were randomly divided into two groups: cutting balloon(38 cases) and conventional balloon angioplasty(31 cases) group. Quantitative coronary angiography(QCA) and intravascular ultrasound(IVUS) were underwent before and immediately after the balloon inflation. Within 6-months clinical and angiographic follow-up, clinical improvements and QCA results were recorded. himary end points included myocardial infarction, coronary artery bypass graft(CABG) and revascularization. Results The procedural success rate was 100% in both groups. One patient in cutting balloon experienced dissection in the site distal to stent. Average follow-up time was (6.7?0.3) months. The angiographic stenosis rates at the 3- and 6-month in cutting balloon group were markedly lower than that in conventional balloon group(15% and 38% vs 18% and 43%, respectivelly, P

OBJECTIVE:To compare the effects of dezocine and nalbuphine on patient-controlled intravenous analgesia(PCIA) in patients undergoing cesarean section. METHODS:A total of 97 patients undergoing selective cesarean section were selected from our hospital during Jun. 2015 to Mar. 2017. They were divided into dezocine group(52 cases)and nalbuphine group(45 cases) according to lottery. Both groups received cesarean section under combined spinal-epidural anesthesia,and then given PCIA pump immediately after surgery. The pump of dezocine group was Dezocine injection 0.5 mg/kg+Tropisetron hydrochloride injection 10 mg;that of nalbuphine group was Nalbuphine hydrochloride injection 2 mg/kg+Tropisetron hydrochloride injection 10 mg. Both groups of analgesic drugs were diluted 100 mL with 0.9% sodium chloride injection,constant infusion of liquid medicine at rate of 2 mL/h,adding 0.5 mL additionally each time,for consecutive 48 h. VAS score and Ramsay sedation score of resting pain, dynamic pain and uterine contraction pain were performed in 2 groups 4,8,12,24,48 h after surgery. The serum levels of PRL were determined 30 min before surgery and 24,48 h after surgery. The initial time of lactation and ADR were recorded in 2 groups. RESULTS:VAS score of resting pain and uterine contraction pain at 4,8,12 h after operation and that of dynamic pain at 4,8,12, 24 h after operation were significantly lower in dezocine group than nalbuphine group,with statistical significance (P＜0.05). There was no statistical significance in VAS score between 2 groups at other time points(P＞0.05). As time went on,the VAS scores of the two groups decreased significantly at each time point,and the difference was statistically significant(P＜0.05). The serum levels of PRL in 2 groups 24 and 48 h after operation were significantly higher than 30 min before operation,with statistical significance(P＜0.05). There was no statistical significance in serum level of PRL between 2 groups at same time point(P＞0.05). There was no statistical significance in Ramsay score, initial time of lactation or the incidence of ADR between dezocine group and nalbuphine group (P＞0.05). CONCLUSIONS:Both dezocine and nalbuphine are effective analgesia drugs of PCIA in patients undergoing cesarean section. Early postoperative analgesic effect of dezocine is superior to nalbuphine. They have similar effects on long-term analgesia and postoperative sedative,serum level of PRL,initial time of lactation,as well as safety.

BACKGROUND: The area of myocardial infarction is the determinative factor of acute myocardial infarction prognosis. Amelioration of blood transportation and replacement therapy can reduce infarction area. Bone marrow mesenchymal stem cells can differentiate into cardiovascular tissue and are easy to obtain. After cultured and expanded in vitro, they can become the ideal cells for cardiovascular replacement therapy.OBJECTIVE: To evaluate the therapeutic effect of intracoronary transplantation of bone marrow mesenchymal stem cells in the treatment of myocardial infarction. DESIGN: Self-control observation taking the patients as subjects.SETTING: Department of Cardiology, Department of Nuclear Medicine,Echocardiogram Room, Nanjing First Hospital Affiliated to Nanjing Medical University.PARTICIPANTS: Totally 20 patients with acute myocardial infarction who received the therapy of bone marrow mesenchymal stem cells transplantation in the Department of Cardiology, Nanjing First Hospital Affiliated to Nanjing Medical University during March 2003 to March 2004 were recurited. Informed consents were obtained from the patients, and the complete postoperative follow up was over 3 months. The patients include 15 male and 5 female, and they were aged (64±10) years.METHODS: All the patients underwent percutaneous coronary intervention (PCI) to treat infarction-related blood vessel. Autologous bone marrow was taken from the patients, then stem cells were extracted to be performed in vitro induction, differentiation and proliferation, and transplanted infarction-related blood vessel through coronary artery at the mean number of (21.7±30.14)× 107 within 2 weeks. Before and 3 months after transplantation of stem cells, patients underwent gated dual-isotopic myocardial perfusion/metabolic imaging (18-fluoro-2-deoxy-glucose, 18F-FDG) examination. Survived and necrotic myocardia were predicted and infarction area was obtained. At the same time, wall motion and heart function index were evaluated with ultrasound cardiography (UCG)examination, and they were re-checked 3 months after operation to evaluate the amelioration of wall motion and heart function index. A 5-point scale was used in the evaluation of gated dual-isotopic myocardial perfusion/metabolic imaging (18F-FDG) examination: point 0: normal, 1: sparse, 2:obviously sparse, 3: defected. Evaluative standard of UCG: point 1: normal,2: reduced, 3: obviously reduced, 4: no ventricular wall motion or paradoxical motion; Wall motion with 2 points or more than 2 points suggests it is improved.MAIN OUTCOME MEASURES: ① Results of gated dual-isotopic myocardial perfusion/ metabolic imaging (18F-FDG-SPECT); ②Infarctionrelated myocardial segment score and heart function index before and after stem cell transplantation of patients in ECG follow-up observation.RESULTS: All the 20 patients participated in the result analysis.Results of gated dual-isotopic myocardial perrusion/metabolic imaging (18F-FDG-SPECT): The myocardial perfusion defect area of 20 patients was significantly reduced after therapy than before therapy [(33±15)%,-(44±18)% ,P ＜ 0.05]; Metabolie defect area was significantly reduced after therapy than before therapy [(33±17)%, (43±21)% ,P ＜ 0.05];Before therapy, there were 199 segments, in which blood flow reperfusion was matched to glycometabolism defect, and they were determined as necrotic myocardium. After therapy, blood flow perfusion metabolism was improved in 79 segments, but blood flow perfusion and glycometabolism were not improved significantly in 120 segments (P ＜ 0.05). Results of UCG: ejection fraction of patients was significantly larger after therapy than before therapy [(53±8)%, (42±7)% ,P ＜ 0.05].CONCLUSION: Intracoronary transplantation of human bone marrow mesenchymal stem cells for treating myocardial infarction is simple to operate. After therapy, the infarction area is obviously reduced, myocardial blood flow perfusion and metabolism of necrotic area improve, myocardial segments without survival determined before operation reduce sigrificantly and the heart function of patients improve.
