Objective To study clinical characteristics and diagnostic methods of lymphoma with chest invovement. Methods Twenty-five lymphoma patients with chest involvement were retrospectively analysed, they were all diagnosed in Peking University Third Hospital during 2000 to 2007. The data were collected including clinical manifestations, blood examinations, chest X-ray and CT scan, diagnostic methods and pathologic diagnosis. Results The median age of the 25 patients was 46 years old. Pyrexia(13 cases), weight loss over 10 percent in 6 months(11 cases), cough(10 cases), shortness of breath(9 cases) and painless enlargement of the peripheral lymph nodes(16 cases) were common manifestations. Erythrocyte sedimentation rate and serum lactate dehydrogenase(LDH) level were increased in 72.7% and 81% patients, respectively. The enlargement of mediastinum lymph nodes(16 cases, 64%) was the most common presentation of chest radiography, followed by pulmonary involvement(15 cases, 60%) including infiltration or pulmonary consolidation, mass, multiple nodules, diffuse ground-glass shadow, miliary lesion. There were also presentations of pleural effusion(10 cases, 40%), pericardial effusion(4 cases, 16%), chest wall mass(2 cases, 8%). Eighteen patients(72%) had at least two kinds of these presentations. The appearance of pleural effusion were yellow turbid, bloody or chyliform. Rivaha tests were all positive. The median value of plearal effusion examinations were listed as follows: specific gravity 1.031, total cells 9800×10~6/L, WBC 6.72×10~9/L, lymphocyte 86%, neutrophil 14%, protein 31.4 g/L, LDH 296 U/L,adenosine deaminase (ADA) 67.4 U/L Most patients(16 cases) were diagnosed by surgical biopsy,especialy peripheral lymph nodes biopsy (12 cases). Other patients were diagnosed by ultrasound or CT-guided biopsy (5 cases), video-assisted thoracoscopic pleural biopsy (1 case), video-mediastinoscopic mediastinum lesion biopsy(1 case), bronchial mucosa biopsy through bronchoscope(1 case), bone marrow examination(1 case). All the cases were non-Hodgkin lymphoma except one. Conclusions There was no specific clinical manifestation for lymphoma with chest involvement, but in almost half of patients there were enlargement of not only peripheral but also mediastinum lymph nodes. And there were some characteristics in serum, pleural effusion, chest X-ray and CT scan. Surgical biopsy of peripheral lymph nodes was a simple and convenient method for diagnosis. Micro-invasive biopsy had good diagnostic value for lymphoma with chest involvement, including ultrasound-or CT-guided biopsy for superficial mass, pleura, lung, liver, spleen and deep lymph nodes, video-assisted thoracoseopic and video-mediastinoscopic biopsy for pleura, lung and mediastinum lesions. But bronchial mueosa and lung biopsy during bronchoscopy had a low diagnostic rate for lymphoma.

After the concept and characteristics of public health emergencies were described , the advantages and possibility of medical library to provide service for public health emergencies were analyzed with suggestions put for-ward for medical library to provide service for public health emergencies,such as perfecting emergency measures and service mechanisms ,cultivating active and advance service awareness ,developing special database ,establishing close communication with related institutions, enforcing network construction and maintenance,and improving librarians'literacy.

Objective To explore the influence of the sequential enteral nutrition(SEN) on nutritional status and prognosis in patients with acute cerebral infarction(ACI).Methods 80 ACI patients complicated with dysphagia were divided into SEN group and control group(40 cases in each group).In the first three days patients in SEN group were treated with nasal feeding short-peptide enteral nutrition[84~126(kJ/kg.d) ],than,which would be replaced with nasal feeding integral-protein enteral nutrition from the forth day.Patients in the control group were provided with ordinary fluid food by nasal feeding.Nutrition support for both groups was at last more than 10 d.In the 1 d,7 d and 14 d after treatment,data of both groups concerned with triceps skin fold(TSF),mean upper arm muscle circumference of triceps(MAMC),serum albumen(Alb),serum prealbum(PAB),heamoglobin(Hb),incidence of infectious complications,National Institutes of Health Stroke Scale(NIHSS) score and Barthel index(BI) were examined.Results Nutritional indexes(TSF,MAMC,Alb,PAB,Hb) in the SEN group were significantly higher than those in the control group(P

Objective To discuss the correlation factors of locally recurrent gastric carcinoma. Methods Clinical, pathological and periodical follow-up datas of 50 cases with locally recurrent gastric carcinoma after radical resection from 1991 to 2005 were studied retrospectively, logistic regression analysis was used to disscuse the possible correlation factors of locally recurrent gastric carcinoma. Results 66.0% of 50 cases had recurrenced within 2 years after operations; Tumor pathological stages, positive lymph nodes and radical resection extent were independent correlation factors of locally recurrent gastric carcinoma. Conclusions Most recurrences would happen within 2 years after radical resection for gastric carcinoma; Early diagnosis of reccurrent gastric carcinoma depends on periodic follow-up observation especially gastroscope; Tumor pathological stages, positive lymph nodes and radical resection extent are independent correlation factors of locally recurrent gastric carcinoma.

Objective To understand the perceptions of normal and ideal body size in registered nurses and nursing students,and to analyze the impacts of individual weight levels and misperception of body weight on their such cognitions.Methods A cross-sectional survey of 407 nursing students from two hospitals and 466 registered nurses from one hospital was conducted with the questionnaire survey.Sociodemographic information,actual weight,perceived weight levels and scores for figure rating scale were included.Results FRS scores for normal and ideal body size to male were significantly higher than to female either in registered nurses or in nursing students; FRS scores for ideal body size to both sexes were significantly lower than those for normal body size among registered nurses and nursing students.There were no statistically significant associations between FRS scores for normal and ideal body size and individuals' weight levels and misperceptions of body weight among registered nurses and nursing students.Conclusions There existed differences in rating female and male body size among registered nurses and nursing students,with “bigger” normal and ideal body sizes to male,Nurses preferred to “thinner” ideal body size in comparison to normal body size.

ObjectiveTo investigate the expression levels of vascular endothelial growth factor (VEGF)in knee synovial membranes and synovial fluids whether it could be a marker for progressive osteoarthritis.MethodsKnee synovial membranes and synovial fluids of patients with osteoarthritis who were underwent total knee arthroplaaty or arthroscopy were collected. They were classified into four groups according to the radiographic grading[Kellegren-Lawrence(K-L) grade]. Appoint K-L-0-grade patients who suffered from menisci injuries only served as controls. The levels of VEGF in the synovial fluid were measured by enzymelinked immunosorbent assay(ELISA) and VEGF-secreting cells were identified by immunohistochemistry.ANOVA was used for statistical analysis. ResultsVarious degrees of inflammation could be found in all the samplesevaluated histologically on HE-stained sections. Synovial tissue inflammation presented as synovial lining thickening, and inflammatory cells infiltration. VEGF expressed in the synovium linings and surrounding blood vessels. The VEGF levels in the synovial fluids were increased accordingly with K-L grades, which reached the peak level in the late stage of osteoarthritis. The levels of VEGF in the synovial fluids were significantly higher in patients with osteoarthritis[from (1181±116), (1632±140) to (2252±216) pg/ml]than in those with menisci injury (P＜0.01); The percent ages positive cell in each groups were (5±4)％ , (9±4)％,(16±6)％ and (21±6)％ respectively, there were significantly differences too (P＜0.01). ConclusionVEGF originated from synovial tissue may play a role in the pathogenesis of osteoarthritis. High levels of VEGF in the synovial fluids can be regarded as the marker of active osteoarthritis.
