Objective To investigate the role of expression in the differential diagnosis of thyroid follicular carcinoma and follicular variant of papillary carcinoma. Methods Seventy cases of thyroid lesions (including 15 cases of follicular adenomas, 15 cases of adinomatous goiters, 30 cases of papillary carcinomas and 10 cases of follicular carcinomas) were collected, and CD10 expression was detected by means of immunohistochemistry in above thyroid lesions. Results Seven of 9 cases of follicular variant of papillary carcinoma were CD10 positive (77.8), and 8 of 10 cases of follicular carcinoma were CD10 positive (80.0). However, CD10 was negative in all cases of non-follicular variant of papillary carcinoma, follicular adenoma, adinomatous goiter and normal thyroid tissue. Conclusion The detection of CD10 expression is useful to the differential diagnosis of thyroid follicular carcinoma and follicular variant of papillary carcinoma.

Objective To find out the clinical characteristics and morbility factors of intravascular catheterrelated bloodstream infection(CRBSI). Methods Totally 21 patients who had CRBSI in neonatal intensive care unit were investigated retrospectively. Results The distribution of CRBSI was higher in very low birthweight preterm infants, gestational age among 28 ～34week, whose intravascular catheter remaining time were obove three weeks. Principal clinical presentation of CRBSI were poor feeding, unaocountable tachycardia, temperature instability, stressed hyperglycemia,refractoriness metabolic acidosis. The most common pathogens were coagulase-negative staphylococci (35.7%), Klebsiella pneumonia, bacilli ( 11.9% ) Staphylococcus aureus (9.5 % ), Pseudomonas aeruginosa( 7. 1% )and Enterobacter cloacae(7.1% ). Conclusions The clinical manifestations of CRBSI were concealment,and reducing the time of inserted central catherization and total parenteral nutrition, strengthening the nutrition of body would provide effective prevention of CRBSI.

Objective To study the effect of acute lymphoblastic leukemia (ALL) children bone marrow mesenchymal stem cells (MSCs) on the resistance of K562cell atd mechanism in vitro.Method MSCs were obtained from AL children bone marrow after derivation, cultivation and identification.The coculture of MSCs and K562 and K562 suspension were established.Effects of MSCs on the growth of K562 cells were investigated in vivo.The two kinds of cells treated with different concentration of adriamycin (ADM) and the rate of apoptosis was evaluated by flow cytometry.Cell cycle was determined by flow cytometry.RT-PCR was used to detect Bcl-2 and Bax in K562 cells.Result Compared with the cell growth curve of K562 alone, the K562 cell co-cultured with MSCs grew slower and the exponential phase of growth was not obvious.The apoptosis index of the K562 cells co- clutured with MSCs was (9.19 ±0.53)% examined by flow cytometry, and that of the K562 cells alone was 4.00 ± 0.37% respectively( P ＜ 0.05 ).The percentage of cells at G0/G1 phase was (50.2 ± 2.26) % and that at S phase was (37.03 ± 3.50) % in the group of K562 alone, but those of the K562 cells co - cultured with MSCs were (80.95 ± 3.83) % and ( 17.40 ± 1.50)% respectively( P ＜0.05).The result of RT-PCR suggested expression of Bcl-2/Bax of the K562 cell co-cultured with MSCs was higher than K562 alone.Conclusion ALL children MSCs suppressed the growth of K562 cell in vitro.Adhesion made K562 depress sensitive to ADM.The mechanism was perhaps caused by adhesion with MSCs, K562 cell cycle was changed and related to Bcl-2 gene high level expression.
