Ocular signs and serum vitamin A concentration are commonly used tor the diagnosis of vitamin A deficiency. Recently, impression cytology was suggested as a method for early detection of vitamin A status. Twenty patients with normal eyes and digestive disease, and 111 children with normal eyes were evaluated by serum vitamin A concentration, relative-dose-response and conjunctival impression cytology test. About 90% of the patients with normal conjunctival impression cytology has normal vitamin A status. About 70% of the patients with abnormal conjunctival impression cytology has abnormal vitamin A status despite their seemingly normal clinical ocular examination, and so did the children. These results suggest that impression cytology can identify individuals with preclinical vitamin A deficiency.

Objective: To study tumor chemotherapy on IL-2R express in peripheral blood cells of patients with malignant tumors.Methods: CD + 25 cells percentage rate of peripheral blood cells in patients with or without chemotherapy was done.Results: CD + 25 cells percentage rate in malignant tumor was lower than those of normal contrlos (P

UNLABELLED: A female patient of 56 years old had hoarseness that seems worse after talking excessively,which occasionally associated with slightly sore throat and pharyngeal foreign body sensation. The symptoms are not associated with sore throat, fever, night sweats, not drinking cough, breathing and swallowing difficulties, but no cough, bloody sputum. Neck ultrasound can be showed: goiter and real echo uneven thickening, increased blood supply pan; the right thyroid lobe multiple cysts pan. Enhanced CT shows occupying lesions were found out in the right side of the supraglottic larynx gap and the right lobe of the thyroid, nature to be determined. Full thyroid function showed: thyroid microsomal antibodies 278.2 u/ml, the rest of the indicators in the normal range. Other routine preoperative examinations were normal. Immunohistochemistry: CD45(++) CD68(+) CD99(++) EMA(-) CK(-) Sclc(-) TTF-1(--) CgA(-) SY(-) NSE(--) S-100(-) ESA(-). Supported by immunohistochemistry, hyperplasia organizations was diffuse lymphoid tissue. Through expert consultation by superior hospital the pathology showed: Hashimoto's thyroiditis with thyroid papillary carcinoma (lesions of the right thyroid); Lesion on the right side of the throat gene rearrangement results show: B lymphocyte clonal consider mucosa-associated extranodal marginal zone B-cell lymphoma the gene rearrangement that the right side of the throat disease is: B lymphocyte clonal, be considerd mucosa-associated extranodal marginal zone B-cell lymphoma. DIAGNOSIS throat B-cell lymphoma; thyroid papillary carcinoma (right side); Hashimoto's thyroiditis (right side).

Objective:To assess the genetic relationship of clinical isolates of carbapenem-resistant A.baumannii (resistant to both imipenem and meropenem) from January 2007 to March 2008 in Peking University Third Hospital for measures to decrease the isolates; to investigate the characteristics of patients with carbapenem-resistant A. baumannii colonization or infection and to evaluate antibiotic treatment for health care-associated infections caused by carbapenem-resistant A. baumannii. Methods: The medical records of patients with carbapenem-resistant A. baumannii colonization or infection were reviewed. Antibiotic susceptibilities of the isolates were determined by the standardized disk-diffusion method and the clonal relationship of the isolates was analyzed by pulsed-field gel electrophoresis. Results: A total of 49 carbapenem-resistant A. baumannii strains were isolated from the 49 patients hospitalized during the study period and pulsed-field gel electrophoresis typing yielded 7 different patterns. A total of 45 (91.8%)genotyped strains showed clonal relationship. The most frequently identified predisposing factors were intensive care unit stay, invasive procedures, and hypoalbuminemia. Chronic obstructive pulmonary disease (12 cases) and cerebrovascular disease (10 cases) were the most common comorbid conditions.The mortality of patients with carbapenem-resistant A. baumannii infection was 38. 1% (8 of 21 patients), and the acute physiology and chronic health evaluation Ⅱ score, initial antibiotic therapy failure rate and the presence of hypoalbuminemia were significantly increased in the death group. Combination therapy regimens had higher success rates than monotherapy regimens (11/13, 84. 6% vs. 3/17,17.6%). Conclusion: There has been clonal spread of carbapenem-resistant A. baumannii strains among patients in our hospital since 2007. Intensive care unit stay, invasive procedures, hypoalbuminemia, chronic obstructive pulmonary disease and cerebrovascular disease were common in patients with carbapenem-resistant A. baumannii colonization or infection. Antibiotic combination therapy may be effective for carbapenem-resistant A. baumannii infection.

The energy expenditure in the late stage of pregnancy was studied. The workers of three kinds including spinner, sewers and kindergartners were selected, and ten healthy pregnant women were matched to non-pregnant as subjects. Energy consumption was measured by indirect method and calculated from dietary survey. The results showed that the energy expenditure for spinner, sewer and kindergartner in pregnancy was 9.5474, 10.1253 and 8.7287 MJ/day, but for non-pregnant woman was 9.4453 10.1281 and 8.1567 MJ/day respectively. Calorie intake was 10.8910, 11.2424 and 9.9830 MJ/day for pregnant women, but 9.2215, 10.4474 and 8.6734 MJ/ day for the non-pregnant women respectively. The difference of energy consumptions between the pregnant and non-pregnant women was not significant, but the calorie intake for the pregnant women was signigicantly higher (0.8368 MJ/day) than the non-pregnant. According to the energy consumption, we recommend the calorie intakes in the late stage of pregnancy may increase 0.8368 MJ/day.

Objective To evaluate left ventricular systolic synchronicity in patients with dilated cardiomyopathy by V-plane imaging and compare with clinical commonly used tissue Doppler imaging (TDI),evaluate the relevance and consistency between these two parameters.Methods 20 patients diagnosed with DCM and 20 healthy controls were enrolled,2D images,V-plane imaging and TDI waveform were acquired.Time to peak velocity of left ventricular 12 segments were measured by TDI and the standard deviation (TDI_SD) were calculated.Displacement time to peak were measured by V-plane and the standard deviation (V-plane_SD) were calculated.Results Compared with control group,TDI_SD and V-plane_SD increased significantly (P ＜ 0.01),TDI time to peak increased and V-plane time to peak decreased significantly(P ＜0.01).In the two group,12 segment time to peak measured by V-plane were significantly higher than TDI(P ＜ 0.01).There was a significant correlation between TDI_SD and V-plane_SD (r =0.925,P ＜0.001).Bland-Altman plot showed that 95％ plots of ratio of TDI_SD and V-plane_SD were among limits of agreement,which was (0.50,1.36).Conclusions Left ventricular systolic synchronicity in DCM patients can be observed by V-plane imaging.V-plane has significant relevance and consistency with TDI,and can overcome the limitations of TDI that 12 segments can not be displayed in the same cardiac cycle.
