Objective To observe the effect of liver disease special-purpose enteral nutrition preparation on protein metabolism and liver function in children with liver injury.Methods Sixty cases of severe ill with liver injury in hospital,with mean age of (7.8?6.3) years old.All patients were randomly divided into experimental group (n=30) and control group(n=30).The experimental group was treated by adding the liver disease special-purpose enteral nutrition preparation homogenized diet and control group was treated by adding entire protein entire nutrition type enteral nutrition preparation.All patients in both 2 groups were nasally fed with intestinal nutrition,which contained 418-628 kJ/(kg?d).One day before nutritional support and 14 days after nutritional support,the liver function,total serum protein,albumin,hemoglobin were recorded.SPSS 11.5 software was used to analyze the data.Results The baseline indicators were similar before nutritional supports.Fourteen days after nutritional support,alanine aminotransferase(ALT) and aspartate aminotransferase(AST) were all significantly lower in experimental group than in control group(Pa

This study was purposed to investigate the role of cytokines in pathogenesis of lymphoma-associated anemia. The levels of IFN-γ, IL-1β, IL-6, TNF-α and EPO in serum from 45 lymphoma patients and 12 normal controls were detected by using ELISA, the EPOR level on bone marrow cells were detected by flow cytometry, the CFU-E of bone marrow cultured in vitro was counted under inverted microscope. The results showed that 25 (55.6%) out of 45 newly diagnosed lymphoma patients had anemia before diagnosis, 13 (28.9%) had anemia during therapy, 7 (15.5%)never had anemia. The IFN-γ and TNF-α levels in serum of patients with moderate and severe anemia were significantly higher than those in patients with mild anemia and without anemia as well as normal controls. The EPO, IL-6 and IFN-γ levels correlated negatively with Hb concentration in patients, the EPOR level in patients without anemia significantly higher than that in patients with anemia and normal controls. The bone marrow CFU-E amount in patients showed positive correlation with Hb and EPOR levels. It is concluded that the increased IFN-γ, TNF-α and IL-6 may contribute to the anemia in lymphoma, and yet the EPO and EPOR levels are elevated to balance negative regulatory effects on hematopoiesis and maintain normal hematopoiesis.

OBJECTIVETo evaluate the effect of Yufeining, a traditional Chinese medicine, on induced sputum interleukin-8 (IL-8) in patients with chronic obstructive pulmonary disease (COPD) at the stable phase.

METHODSThirty-six patients with COPD were divided into trial group (18 cases) and control group (18 cases) randomly. The trial group was treated with Yufeining pills taken orally for half a year; the control group was not given any medicine. Routine lung function was recorded before and after treatment. Total cell count (TCC), differential cell counts (DCCs) and IL-8 in induced sputum were determined at the baseline and 6 months later.

RESULTSThe indices of lung function improved significantly after 6 months' treatment in trial group (P < 0.05); TCC and absolute neutrophil count decreased significantly compared with baseline in the trial group (P < 0.05); Sputum IL-8 concentration dropped significantly after 6 months' treatment, from a mean of 5.216 +/- 2.914 microg/L to 4.222 +/- 2.140 microg/L (P < 0.05). There were insignificant changes in the parameters in the control group between baseline and 6 months later.

CONCLUSIONYufeining could improve lung function, decrease sputum TCC, absolute neutrophil count and IL-8 concentration, and relieve airway inflammation in patients with COPD in the stable phase.

OBJECTIVETo investigate the expression differences of minichromosome maintenance 2 (MCM2) mRNA and protein among colon adenocarcinoma, colon adenoma and normal mucosa, and among different clinicopathological types of adenomas.

METHODSFifty specimens, including 33 colonic adenomas, 12 colonic adenocarcinomas and 5 normal colonic mucosa were selected. Each specimen was divided into two parts, one for immunohistochemistry and the other for real-time RT-PCR. Expression differences of MCM2 mRNA among the colonic adenocarcinoma, adenoma and normal colonic mucosa were evaluated by REST-XL software.

RESULTSThe expression of MCM2 was observed in the basal third to half of the colonic crypts in normal mucosa, while throughout the epithelium in the colonic adenocarcinomas and adenomas. However, the expression of MCM2 mRNA in the adenocarcinomas was significantly higher than that in the adenomas(P=0.001). The MCM2 mRNA expression was elevated in the adenoma with villous type, in the conditions of high-grade dysplasia, larger size, sessile morphology and in patients of older ages, but the difference was not significant by REST-XL (P>0.05).

CONCLUSIONThe difference of MCM2 expression between the adenoma and the adenocarcinoma indicates its potential value in the early diagnosis of colonic cancer.

OBJECTIVETo explore the mechanism of 'erythroblast island (EI)' formation in the bone marrow of patients with immun-related hemocytopenia (IRP).

METHODSThe category of BM-auto antibody (au Ab) in 48 patients with IRP was detected with FCM. The BM-au Ab in the 'EI' of these cases were explored with immuonhistofluorescence (IF). Clinical and laboratory characteristics of these cases were also analyzed retrospectively.

RESULTSIgG could be detected in the 'EI' on the BM smear of 14 cases (29.17%), BM-au Ab mainly deposited at the edge/membranes between macrophage and erythroblasts rather than cyto plasm. Positive reaction were seen in all the cases with GlycoAIgG. The red blood cell count [(1.8 ± 0.5) × 10(12)/L] and hemoglobin level [(59.6 ± 16.2)g/L] were significantly lower than that in the IF(-) group [(2.5 ± 0.9) × 10(12)/L and (83.4 ± 25.0) g/L] (P < 0.05). The percentage of reticulocyte [(2.0 ± 0.8)%], serum level of IBIL [(9.4 ± 4.7) µmol/L], percentage of erythroblats in sternum BM (0.441 ± 0.139) and response rate to therapy (85.7%) in IF(+) group were significantly higher than that in IF(-)group [(1.3 ± 1.0)%, (6.6 ± 6.7)µmol/L, 0.298 ± 0.082, 61.3%, respectively] (P < 0.05).

CONCLUSIONMacrophage was connected with erythroblasts through autologous IgG in the 'EI's of some patients with IRP. 'EI' were the places where macrophages devoured and destroyed erythroblasts rather than erythroid development and differentiation. The pathogenetic mechanism of IRP might be associated with macrophages phagocytosing and destroying BM hematopoietic cells.
