OBJECTIVE:To compare amiodarone and cedilanid in the treatment of paroxysmal atrial fibrillation(AF) with intravenous administration and control of heart rate.METHODS:47 AF patients were randomly given 150～600 mg amiodarone(amiodarone group,n=24) and 0.2～0.6 mg cedilanid(cedilanid group,n=23) intravenously.The outcome,change of heart rate and adverse drug reaction of 2 groups were observed.RESULTS:Effective rate of amiodarone group was significantly higher than that of cedilanid groups(P

OBJECTIVE: To study the treatment effect of CO2 laser and self-made laryngeal dilator on the laryngeal stenosis. METHOD: Twenty-five patients with laryngeal stenosis were treated with CO2 laser and self-made laryngeal dilator. The laryngeal cavity scar was resected as much as possible by using CO2 laser and the laryngeal cavity was exposed by placing laryngeal dilator under general anesthesia. RESULT: The 24 cases of all were successfully decanulated 1 to 12 months after operation and could breathe freely. One case had second operation and was successfully decanulated 9 months after operation. The follow-up for 1 to 2 years showed all cases speaking well and 3 cases recurrence. CONCLUSION The method for treating laryngeal stenosis using CO2 laser and self-mande laryngeal dilator is effective, fewer complication, less invasive, and faster recovery. The laryngeal dilator is made simply and conveniently.

Objective To investigate the in vitro inhibitory effect of LIGHT on human esophageal carcinoma cells. Methods LIGHT Fc expression vector was transfected into human esophageal squamous carcinoma cell line, Eca109. The inhibitory effect of LIGHT gene on cell growth was detected by MTT and cell growth curve. The expressions of LT?R and HVEM were detected by RT PCR. Results Expression of LIGHT Fc gene could inhibit Eca109 cell proliferation. The growth curve of Eca109/LIGHT was significantly lower than that of the control group in the culture medium containing 1% FCS. MTT test showed that there was significant difference in cell viability between Eca109/LIGHT and the control group ( P

Objectives To investigate the adverse effect of manganese exposure on the iron metabolism in peripheral blood of professionally exposed workers. Methods The manganese in air was collected using personal air sampler, and the time weighted average (TWA) concentration of exposure to manganese was then calculated. The subjects were divided into exposure group (n=85) and control group (n=80) based on the exposure doses they received. The concentrations of iron and manganese in the plasma and blood cells of the subjects were determined using flame atomic absorption detector and graphite furnace atomic absorption detector. Serum ferritin, transferrin, transferrin receptor and total iron binding capacity were determined using enzyme linked immunosorbent assay. Results The manganese contents in both plasma and blood cells were much higher in exposure group than in control group (P<0.01). Compared with the control group, the iron contents in both plasma and blood cells, serum transferrin receptor and total iron binding capacity decreased (P<0.01), while serum ferrin and transferrin increased (P<0.05 and P<0.01) in workers with professional manganese exposure less than 5 years. While in those workers undergoing manganese exposure equal to or longer than 5 years, the iron content of plasma and serum transferring receptor decreased (P<0.05 and P<0.01), and serum transferrin increased (P<0.01). The blood cell manganese content was lower (P<0.05) and blood cell iron level higher (P<0.05) in workers with professional manganese exposure equal to or longer than 5 years than in those workers with manganese exposure less than 5 years. However, no difference was found in other indexes between two groups (P>0.05). It was revealed by linear correlation analysis that no linear correlation existed between the professional exposure time and manganese and iron contents in both plasma and blood cells, serum ferrin, transferrin, transferring receptor and total iron binding capacity (P>0.05). Conclusion The long-term exposure to high dose manganese may result in an imbalance of iron metabolism in the peripheral blood in exposed population, manifesting a decrease of plasma iron and serum transferrin receptors, and an increase of serum transferrin.

Objective To compare the effects of penequinine hydrochloride and atropine on the cardiovascu-lar stability about preoperative in children by monitoring and recording the HR, MAP, SpO2, ECG changes. Methods 40 children underwent selective operation were randomly divided into two groups, 20 in each group. Penequinine hydrechloride group(group A) and atropine group(group B) were injected intramuscularly with penequinine hydro-chloride 0. 015mg/kg or atropine 0. 015mg/kg respectively, at 30 minutes before operation. Patients' HR, MAP, SpO2 and ECG changes were recorded at 10min,20min,30min and 40min after injection. Results The HR,MAP,SpO2 levels of group A and SpO2 level of group B had no significant changes. There are significant changes in HR,MAP of group B. Conclusion Penequinine hydrochloride can be used as preoperative medication and it is conducive to the maintenance of cardiovascular stability.

0.05).CONCLUSION:Nedaplatin combined with docetaxel is effective and safe for advanced NSCLC with high short-term efficacy and mild toxic side reaction in digestive tract and kidney.but the long-term efficacy of it require further study.
