Objective To study the effect and its mechanism of coronary stenting on blood levels of P-selectin. Methods Thirty patients who received coronary stenting from September 2003 to September 2004 were included in the study and another twenty six patients who received coronary angiography during the same period were selected as controls. Blood samples were drawn at 1 h before and at 1 h, 4 h, 24 h, 48 h, 1 week after coronary stenting. Blood samples were taken at 1 h before and at 1 h, 4 h, 24 h after coronary angiograpy. Results In patients with coronary stenting, P-selectin levels after the procedure were significantly higher than that before the procedure (P

Cajanin preparation could significantly reduce the mouse pinna inflammation iuduced by croton oil. The higher the dose, the stronger the effect .It also inhibited the infiltration increase of intraperitoneal blood capillary of mice led by acetic acid.In addition, the preparation had an analgesic effect. These experimental results indicated that cajanin may be hopefully developed to a new drug for the treatment of scald trauma, and infection.

Objective: Adopting quantified index to observe and analyze the effect of acute and chronic pain through double-wavelength diode laser. Methods: Using diode laser with the wavelength of 650nm / 810nm to irradiate the special tissues or aching points of patient, selecting different frequency, intensity and time to make treatment. Results: VAS scoring: P<0.05, the total efficient rate is 96%. Conclusions: Treatment with double-wavelength diode laser to various acute and chronic pain is just a definitely good curative effect, and it can release the effects of patient sleeping, daily life, communication with people and life interests caused by pain, and finally enhancing the quality of life.

Objective To evaluate the feasibility of autologous mononuclear bone marrow cells (BMCs) transplantation in patients with anterior myocardial infarction. Methods Twenty-two patients were enrolled in this prospective, nonrandomized, control study (14 patients in cell transplantation group; 8 in control group). All patients underwent standard percutaneous coronary intervention (PCI) and drug therapy. 14 patients in the cell transplantation group were transplanted with autologous mononuclear (BMCs) via a over-the-wire (OTW) balloon catheter slowly placed into the left anterior descending (LAD) coronary artery during inflation. Results One patient in the cell transplantation group died of acute drug eluting stent thrombosis. The other 13 patients and the 8 patients in the control group had no procedure related complications and ventricular arrhythmia. All patients in both groups underwent 3-month and 6-month follow-up, 6 minutes test, 2D Doppler echocardiogram, single photon emission computed tomography and cardiac magnetic resonance imaging (MRI). After 3 months of follow-up, a significant increase of left ventricular ejection fraction (LVEF) determined by ultrasonic cardiography was found [(50.37?7.31)% vs (40.12?5.52)% before transplantation, P =0.000?1] and was also significantly greater compared with the control group [(50.37?7.31)% vs (44.09?3.50)%, P =0.035]. Conclusion The result indicates that selective intracoronary transplantation of autologous mononuclear BMCs seems to be feasible and may improve the left ventricular systolic function.

Objective To compare the image quality and radiation dose between prospective ECG-trigering and retrospective ECG gating technique in coronary artery imaging. Methods 33 patients suspected coronary artery disease were included in this study and divided into experimental group (prospective ECG-triggering coronary artery imaging, heart rate < 65 bpm, 16 patients)and control group (retrospective ECG gating coronary artery imaging, heart rate < 75 bpm, 17 patients). Radiation dose was recorded for statistical analysis. At the same time, image quality was evaluated. Results There were no significant differences in image quality 3.2 msy. Effective dose reduced 76.47 %. Conclusions Prospective ECG gating coronary artery imaging can obtain the similar image quality compared with prospective ECG gating coronary artery imaging but the effective dose reduced 76.47 %. Prospective ECG gating coronary artery imaging has clinical value to peoples who are able to not accept high radiation dose and with low heart rate.

Aim DPF2 has been reported to be involved in pathogenesis of leukaemia and oncogenic activity.However,the role of DPF2 in oncogenesis and pathogenesis of pancreatic cancer remains unclear.Therefore,the present research aims to investigate the effects of DPF2-RNAi on proliferation,apoptosis and cell cycle regulation of a pancreatic cell line,PANC-1 cells.Methods The lentivirus-mediated DPF2-RNAi was employed to knockdown DPF2 expression in PANC-1 cells,and the role of DPF2-RNAi in proliferation,apoptosis and cell cycle regulation of the PANC-1 cells was examined through MTT assay,colony formation assay and flowcytometry assay.Results The lentivirus-mediated DPF2-RNAi middle and high doses(2 μL and 4 μL)significantly decreased the expression of DPF2 in the PANC-1 cells.DPF2-RNAi decreased cell viability and colony formation,and increased apoptosis of the PANC-1 cells.Besides,DPF2-RNAi induced the S-phase arrest and decreased G2/M phase population of the PANC-1 cells.Conclusions DPF2 may play a crucial role in proliferation,apoptosis and cell cycle regulation of PANC-1 cells.Knockdown of DPF2 through lentivirus-mediated DPF2-RNAi may provide experimental basis for finding a new method for therapy of pancreatic cancer.
