Objective To assess the feasibility and the reliability of emergency temporary cardiac pacing under fluoroscopy and nofluoroscopy,and compare to the superiority and inferiority between two groups.Methods Fifty-seven patients were temporarily paced under fluoroscopy and nofluoroscopy by the way which the common bi-pole temporary endocardium pacing electrode was introduced into the right ventricle by the bi-subclavian vein and right internal jugular.Result Twenty-six patients were successfully paced under fluoroscopy,and 27 patients of 31 were successfully paced without fluoroscopy,the other 4 patients were not paced successfully.Besides,there was no any complication in all patients.Conclusion Emergency temporary cardiac pacing without fluoroscopy is utility,saving time and safety,Compared to other method,the effect is proximity and even superior than the way under fluoroscopy.The way of the emergency temporary cardiac pacing without fluoroscopy is applied widespreadly in the work of clinical first aid.

Objective To evaluate the effects of percutaneous long sheath aspiration embolectomy for the treament of acute superior mesenteric artery embolism. Methods 7 cases (atrial fibrillation 4 cases; left atrium myxoma 2 cases and chronic mesenteric ischemia 1 cases) of acute measenteric artery embolism were treated with percutaneous emlolectomy using long sheath (Optimed, Germany) aspiration. Results Successful recanalizations were observed in all of the 7 cases of superior mesenteric arteries. 5 cases out of the 7 cases recovery; 1 case underwent laparotomy; 1 case died in 24 hours. Conclusions Percutaneous embolectomy using long sheath aspiration is a sample and effective method for the treatment of acute superior mesenteric artery embolism.

Objective: To determine the contents of paeoniflorin and glycyrrhizic acid in Gianggan Capsules by RP HPLC. Methods: The Chromatographic method was carried out on Kromasil C 18 column using acetonitrile phosphate buffer solution (pH=5) (20∶80) as a mobile phase. The detection wavelength was set at 230nm and 250nm. The flow rate was 1ml/min. The column temperature was 40℃. Results: The paeoniflorin and glycyrrhizic acid calibration curves were linear at the ranges of 0.48～4.80?g and 1.08～10.81?g(r=0.9999). The average recoveries were 100.5% with RSD 1.2% for paeoniflorin and 98.9% with RSD 0.9% for glycyrrhizic acid. Conclusion: This method is simple, reliable and provides a reference standard for the quality control of Gianggan Capsules.

Objective To investigate the influence of fishbone diagram in the incidence of blood residual after sealing tube indwelling needle in cardiovascular disease patients.Methods Two hundred and ninety-three patients(1,035 times)with sealing tube intravenous indwelling needle were assigned into control group and another 272 ones(1,276 times)with the needle into experiment group according to admission sequence. In the former group the method of conventionally sealing the tube for intravenous indwelling needle was applied and in the latter,fishbone diagram was applied to analyze the key factors for blood residuals and regulate pertinent measures for effective sealing of tube.The two groups were compared in terms of incidence of blood residuals.Result The incidence of blood residuals in the experiment group was significantly lower than that in the control group(P<0.05).Conclusion The fishbone diagram is effective in reducing the incidence of blood residuals after sealing the tube for intravenous indwelling needle by way of taking effective interventional measures after screening out the key influential factors for blood residuals.

Patients with advanced lung cancer should be given proper hospice care .Doctors should not only practice protective medicine on the foundation of laws and regulations , informing the patients about their conditions tactfully , but also try their best to provide the patients with optimal therapeutic strategies , taking the patient's physi-cal tolerance, economy, etc.into account and achieving the goal of humanized and individualized therapy .Mean-while, the construction of professional medical -nursing institution is in urgent need .Only providing general nurs-ing in multiple aspects of illness , mental health , social functions , can we relieve the pain both physically and men-tally, and improve the patient's quality of their terminal times .

AIM:To observe the effects of Liangxue-Jiedu (LXJD) prescription, a Chinese medicine, on the expression of CC chemokine ligand 20 ( CCL20 ) and CC chemokine receptor 6 ( CCR6 ) in imiquimod-induced psoriasis-like skin lesions in a mouse model .METHODS: Male BALB/c mice were randomly divided into control group , model group, LXJD treatment group and chemokine CCL 20 monoclonal antibody treatment group .The mouse model of psoriasis was induced by imiquimod .The severity of psoriasis was assessed by the dermatologists using psoriasis area and severity in -dex (PASI).The morphological changes of the skin tissues were observed under light microscope .The thickness of epider-mis was measured .Real-time PCR was used to detect the expression of CCL 20 and CCR6 in the skin tissue samples .RE-SULTS:The skin in model group showed a large number of scales , erythema and skin thickening .Compared with model group, the skin lesion in LXJD treatment group was attenuated .The erythema and scales were alleviated , the PASI score was reduced , and the expression of CCL 20 and CCR6 was significantly lower than that in model group .CONCLUSION:LXJD prescription down-regulates the expression of CCL 20/CCR6, thus attenuating the psoriasis skin lesions in mice .

Objective To better understand the age related changes of cardiac structure and function and their relationship with gender, body weight and blood pressure. Methods M mode, 2 dimensional, and Doppler echocardiographic studies were performed on 306 healthy intellectuals, including 165 males and 141 females, ranging in age from 30 to 85 years. Results Parameters in both male and female including the ratio of peak E wave to peak A wave velocity(E/A), the ratio of the right ventricular peak E wave to peak A wave velocity(E/Ar), the amplitude of aortic wall (Aao) and the angle between septum and the root of aorta (?) were all decreased with the aging significantly( P

OBJECTIVE:To study the implementation of Prescription Management Method (PMM) in our hospital and to promote rational drug use. METHODS: A total of 71 000 prescriptions were collected from Sept. 2006 to Dec. 2007 (before implementation) and from May to Dec. in 2007 (after implementation) for a statistical analysis and evaluation of the irrational prescriptions. RESULTS: The non-conformity rate of prescriptions was on the higher side before PMM implementation, accounting for 7.76% versus 3.38% after implementation (P

Objective To compare the efficacy and resistance between S?1 combined with radiotherapy and S?1 alone in the treatment of elderly patients with locally advanced gastric cancer. Methods Fifty?eight elderly patients with unresectable locally advanced ( stage Ⅲ) gastric cancer were randomly and equally divided into S?1 combined with concurrent radiotherapy group ( experimental group ) and S?1 alone group ( control group ) . The experimental group received 4 cycles of S?1 treatment with each cycle containing two?week oral administration of S?1 at a dose of 40 mg/m2 twice a day followed by one?week drug withdrawal. Gastric intensity?modulated radiotherapy was performed concurrently with a dose of 45 Gy ( 1. 8 Gy per fraction) . The control group received the same dose of S?1 alone. Short?term outcomes and adverse reactions were evaluated in the two groups. Comparison was made by chi?square test. Results All patients completed the planning treatment. The experimental group had significantly higher objective response, disease control, and symptom remission rates than the control group ( 52% vs. 24%, P=0. 03;76% vs. 45%, P=0. 016;86% vs. 48%, P=0. 005) . There were no significant differences in the incidence of nausea and vomiting, anorexia, leukopenia, diarrhea, or thrombocytopenia between the two groups ( all P>0. 05) . Conclusions S?1 treatment combined with concurrent radiotherapy improves the short?term outcomes and causes tolerable toxicities in the treatment of elderly patients with locally advanced gastric cancer.

AIM: To investigate the effect of histamine and hypoxia on the expression of eNOS mRNA and protein in cultured porcine pulmonary artery and aorta endothelial cells. METHODS: Semi-quantitative RT-PCR and immuno-cytochemistry were used. RESULTS: (1) Histamine increased eNOS mRNA expression in a dose-and time dependent manner. For pulmonary endothelial cells, the effect reached peak when exposed to 10 -5 mol/L histamine in 24 h. eNOS mRNA level was increased to 178 2%?7 7% ( P
