Objective To investigate the functional states of stroke patients using the International Classification of Functioning, Disability and Health (ICF) core sets for stroke. Methods Fifty in-patients with stroke participated in this study. Twenty-five patients less than one month after a stroke were assigned to the acute group, and another 25 patients with more than one month since their stroke were assigned to the sub-acute and chronic group. All the patients were assessed using the Glasgow coma scale, Rankin grading and the Barthel index. The ICF core set for stroke assessment was also used with both groups. The data was analyzed by using a Chi squared frequency test. Results Rankin grades and Barthel indices were significantly different between the two groups, and the functional states in the acute group were better than those in the sub-acute and chronic group. Some of the items, such as consciousness state, functions of structures adjoining the eyes, hearing, substitutive sound, accessory respiration, temperature regulation and protection function of the skin had no significant difference between the groups. The number of patients suffering from disorders of joint motion, joint stability, muscle endurance and control of voluntary movement was significantly greater in the sub-acute and chronic group than in the acute group. Both groups were influenced to different degrees by most of the environmental factors. Conclusion The ICF core sets correctly indicated joint motion, joint stability, muscle endurance and control of voluntary movement difficulties of stroke patients.

Objective To compare the curative effects and safety of immunoabsorption(IA) and double filtration plasmapheresis(DFPP) in treatment of Guillain-Barre syndrome(GBS).Methods 60 patients of GBS were randomly divided into two groups and treated with IA and DFPP,respectively.The neurological functions were assessed and the immunoglobulin,complement and total protein in the blood were also measured before and after treatments.Results The rating of the neurological function deficiency in both groups improved with time,but there was no significant difference in Hughes rating between two groups.After half year,the MRC rating in IA group was better than that in DFPP group((P

A new method is developed to detect vascular edge-line in coronary angiograms.It firstly searches the path through vessel segment of interest,then detects vascular edges along profiles perpendicular to the path.The experiments demonstrate that the method performs well in coronary angiograms with less nearby or overlapping structures and branching vessels.

Dryness is the inherent performance in traditional Chinese medicine. Dryness with a specific efficacy and side effect can be reduced suitably by processing and compatibility in the clinical application. Nowadays domestic scholars have developed research of dryness in traditional Chinese medicine. However, it remains problems such as evaluation index of dryness not clear. This paper takes medical literature mining technology to analyze the historical origin and features of dryness theory. Combing the modern literatures to explicate the dryness' research status and existing problems. Putting forward the traditional Chinese medicine and research should adopt multidisciplinary knowledge and study the system of comprehensive evaluation. Dryness is expected to further application in traditional Chinese medicine clinical research.

ObjectiveTo study the using of cerrobase as the compensation material in the intensitymodulated radiation therapy (IMRT) implementation and impact factors.MethodsWith therapy planning system (TPS) exported the radiation field intensity file (Dicom RT),through measuring the attenuation coefficient of cerrobase,to calculate the processing depth of AUTIMO 3D CNC corresponding for Dicom RT files at each pixel,then using the processed foam casting of Cerrobase,produced the required IMRT compensator.Through the MATRIXX testing the IMRT compensator in clinical implementation.At the same time we compared the MU of using multi-leaf collimator (MLC) and Cerrobase IMRT compensator for 10patients.ResultsWith cerrobase compensation IMRT can get similar dose or dose distribution to dose produced by TPS for point or plane dose,error is within 5％.To comparison with MLC,using cerrobase compensator has fewer treatment times ( (4.44±0.39) min:(5.71±0.57) min (t =10.82,P =0.000) )and fewer MU (462.5 ± 65.8) MU:(524.5±99.6) MU(t=3.14,P=0.012) ).Conclusions Comparison with MLC IMRT,the cerrobase compensation technique has an important application value with its unique advantages.This research provides an implemented method of IMRT radiotherapy for the primaryhospital.

Objective To investigate the impact of prior cerebral infarction (PCI) on in-hospital mortality in patients with Acute Myocardial Infarction (AMI).MethodsA retrospective analysis of documents of a total of 3572 consecutive patients with AMI admitted to Xuanwu Hospital of Capital Medical University from 2002 Jan.1 to 2009 Dec.31 were performed.Results There were 564 patients ( 15.8% )with PCI.Compared with the group of without PC1,the group with PCI were substantially older[(69.4 ±9.9) vs (64.2 ± 12.9)years,P =0.000],and had a higher prevalence of hypertensive disease,diabetes mellitus,prior myocardial infarction (MI) and non-ST-segment elevation myocardial infarction(NSTEMI)( respectively,71.0% vs 57.3%; 41.0% vs 25.7%,12.9% vs 9.5%; 14.9% vs 10.7%,P ＜ 0.01 ),and a higher in-hospital mortality ( 16.5% vs 10.0%,P= 0.000).Univariate analysis demonstrated that in-hospital mortality associated with age,gender,extensive anterior MI,anterior MI,diabetes mellitus,prior cerebral infarction,prior myocardial infarction,coronary angiography and percutaneous coronary intervention.Logistic regression analysis found that risk factors were age,extensive anterior MI,anterior MI,diabetes mellitus and prior cerebral infarction,and protective factors were coronary angiography and percutanous coronary intervention.PCI was independently associated with in-hospital mortality,OR 1.368,95% CI 1.047-1.787,P = 0.022.Conclusion In patients with acute myocardial infarction,the presence of PCI increases the risk of worse in-hospital outcome.
