Objective To study the quality of Pinellia ternata grown in Funan. Methods The contents of free and hydrolyzed amino acids and ephedrine in the samples from four habitats were determined. The components of methanol and acidic ethanol extracts of the four samples were compared by HPLC. The components of petroleum ether extracts of the four samples were compared by TLC. Results The content of amino acids and ephedrine and the kinds of amino acids of P. ternata grown in Funan were almost the same as those from the other three, the main components of methanol and petroleum ether extracts of P. ternata grown in Funan were the same as those from other three. Some components of acidic ethanol extracts of the four samples were different. Conclusion The quality of P. ternata grown in Funan is as good as that of the other three.

Objective To investigate the reasonable perioperative management for elderly patients with esophageal cancer undergon esophagectomy.Methods 92 elderly patients with esophageal neoplasms were treated by esophagectomy.According to the specific pathogenetic condition of the patients,various perioperative managements were provided.After surgery,the operative complications,mortality and 3,5-year survival rate were observed.Results Esophagectomy was carried out for all cases.Cardiovascular and respiratory complications were found in 19,10 respectively.Both of anastomotic stricture and fistulae were found in 4 cases.1 and 2 complicated with chylopleural and disturbance gastric emptying respectively.Mortality was 4.35%,and the 3,5-year survival rate was 80.43%(74/92),34.79%(32/92) respectively.Conclusion Satisfactory perioperative managements are the key to successful esophagectomy.

Objective To provide high-quality health care services to persons whose access is restricted by geography or environment and disaster or battle situation. Methods X-ray equipment was based on embedded Linux operating system, and used OMAP1510 as its hardware developing platform. Telemedicine image workstation was based on Windows operating system, and used VC++6.0 as its software developing platform. Results Telemedicine image workstation could achieve and process images from X -ray machine. Conclusion The system can be applied to real-time acquisition of medical images and telemedicine.

Medical image equipment is used not only to research the structure and principle of imaging equipment but to train the students′ ability of analyzing and solving problems. In order to improve the experiment teaching, simulation devices and practice matches are all involved in.

Objective To evalute the feasibility and safety of sirolimus (rapamycin)-eluting stent for the treatment of in-stent restenosis (ISR). Methods Eleven patients with ISR were treated with one or more Cypher~ TM sirolimus-eluting stents. All these patients received angiographic follow-up at 6 months. Results The success rate of the procedure was 100%. All patients were free of angina after 6 months. There were no repeat revascularizations, stent thrombosis or major adverse clinical events during the follow up period. No ISR was noted in the follow-up coronary angiography. Conclusion This study demonstrates the safety and potential of sirolimus-eluting stents for the treatment of ISR.

Objective To study the incidence of coronary artery aneurysm (CAA) in patients under coronary angiography (CAG), its clinic features and prognosis Methods Retrospective studies were conducted of the clinical features, treatment and outcome of 2?876 patients under CAG Results Among the 2?876 patients, 26 had CAA, the total incidence of CAA was 0 904% Among these patients, 14 had myocardial infarction, and 24 had narrowing coronary artery (stenosis≥50%) Among the 26 cases of CAA, 20 ateries had thrombosis No CAA had ruptured Conclusion The incidence of CAA in the studied CAG population was 0 904%, CAA could be responsible for myocardial ischemia and myocardial infarction

Objective:To evaluate the quality of carbazochrome sodium sulfonate Injection from different manufacturers, analyze the existing problems and provide the reference for the improvement of clinical medication safety. Methods:Statutory testing methods and the exploratory research methods were used to examine the samples, and the quality status of carbazochrome sodium sulfonate Injec-tion was evaluated according to the results. Results:Totally 89 batches of the samples were tested by the current standard. The quali-fied rate was 97. 8%, and the two batches of unqualified samples were carbazochrome sodium sulfonate and sodium chloride Injection with unqualified insoluble particles. Overall, the quality risk of carbazochrome sodium sulfonate for injection was low, and the safety of carbazochrome sodium sulfonate and sodium chloride Injection needed further research. Conclusion:The quality of carbazochrome so-dium sulfonate Injection basically meets the current standard, and the exploratory research suggests that the current standard is imper-fect. It is urgent to improve the related substance detection in the standard and determine the reasonable limits for the degradation im-purities and the other impurities. The clinical medication safety of carbazochrome sodium sulfonate and sodium chloride Injection needs further research.

Objective To design a vehicle-mounted X-ray diagnosis simulation training system based on the field X-ray diagnostic vehicle to solve the problems during its training and utilization.Methods The field X-ray diagnostic vehicle had its internal and external structure analyzed,and was divided into several functional modules.The technologies of computer programming and database were used for the simulation of the modules.An example was given to simulate the operating process of the vehicle by establishing traumatic condition model,war injury image library and etc.esults The system developed realized the simulation training of the vehicle,and the trainee gained feedback after simulation as references.Conclusion The system implements informatized training of the field X-ray diagnostic vehicle,shortens the training period,decreases the training cost and increases the training efficacy.

To investigate the relationship of between p21wAF1 and PCNA expression and the patients' prognosis in breast carcinoma. MethodExpression of p21wAF1 and PCNA was determined by S-P immunohistochemical technique in 152 patients with breast carcinoma. ResultsPositive immunostaining of p21WAf1was detected in 61(40.1% ) primary breast carcinoma, in which 43(70.5% ) were low expression, and 18(29.5% ) over expression of 152 PCNA positive cases, 69(45% ) expressed with low index and 83(55% )expressed with high index. p21wAf1 expression level was correlated with tubule formation (γs＝ 0.341, P＜0.01 ),nuclear atypia(γs=0.516, P＜0.01), mitosis(γs=0.351, P＜0.01)and histological grade(γs=0.415, P＜0.01)in breast cancer tissue. Univariate analysis demonstrated less disease-free survival in patients with higher p21WAF1 (x2 = 6.92, P＜ 0.01 ) and PCNA (x2 = 5.14, P＜0.05)expression than in those with lower expression. The survival term of the patients with p21WAF1 -/PCNA low index, p21wAF1 +/PCNA low index, p21WAF1 +/PCNA high index and p21WAF1 -/PCNA high index groups was successively shortened. Conclusions( 1 ) Combined detection of p21wAF1/PCNA is helpful to judge the proliferating activity of the tumor cells and the patients prognosis. (2) Different expression level of p21WAF1in breast carcinoma is probably related the different regulating directions.
