Objective To explore the effects of lactoferrin on T cells ( the levels of CD4 + T and CD8 +T lymphocytes) and the development of intestinal mucous membrane (villus heights, crypt depths, villus circumferences, and villus areas) in neonatal SD rats. Methods Totally 96 neonatal (one week old) SD rats were equally and randomly divided into twelve groups, in which animals were fed with lactoferrin at a dose of 1.0 g/( kg · d) (dose Ⅰ group), 3.0 g/(kg · d) (dose Ⅱ group), or 5.0 g/(kg · d) (dose Ⅲ group) for 2, 3, or4 weeks,with corresponding blank control groups. Rats in the dosage groups were killed at the set time points and the levels of venous blood CD4 + and CD8 + T lymphocytes were detected using immunofluorescence method. Jejunum ( 1 cm)and ileum (1 cm) specimens were obtained for pathological sectioning, and the villus height, crypt depth, villus circumferences, and villus areas were measured through image analysis system. Results The CD4 + T lymphocyte levels at two weeks were significantly different among dose I group, dose Ⅱ group, and control groups ( all P ＜0. 05).The CD8 + T lymphocyte levels at two weeks were significantly different among dose Ⅱ group, dose Ⅲ group,and control groups ( all P ＜ 0. 05 ). The villus heights, crypt depths, villus circumferences, and villus areas of jejunum at two weeks between feeding groups and control groups were not significantly different ( all P ＞ 0. 05 ), while the condition in ileum was on the contrary. The CD4 + T lymphocyte levels at three weeks were significantly different between feeding groups and control groups ( P ＜ 0. 05 ). The CD8 + T lymphocyte levels at three weeks between dose Ⅲ group and control groups were significantly different ( P ＜ 0. 05 ). The villus heights, crypt depths, villus circumferences, and villus areas of jejunum and ileum at three weeks were significantly different between feeding groups and control groups ( all P ＜ 0. 05 ). The CD4 + T lymphocyte levels at four weeks between feeding groups and control groups were significantly different (P ＜0. 05). The CD8 + T lymphocyte levels at four weeks were significantly different among dose Ⅱ group, dose Ⅲ group, and control groups ( all P ＜ 0. 05 ). Except villus areas of ileum, the villus heights, crypt depths, villus circumferences of jejunum and ileum, and villus areas of jejunum at four weeks were significantly different between feeding groups and control groups ( all P ＜ 0.05 ). Conclusions Lactoferrin can promote the levels of CD4 + and CD8 + T lymphocytes in venous blood and facilitate the development of the mucous membranes of jejunum and ileum. However, such effects are affected by the dose and timing of lactoferrin feeding.

Objective To observe the different expression of somatomedin-receptor in cell membrane of prostate epithelial cells at anoxic or normoxic condition.Methods Human prostate epithelial cells line RWPE-1 were cultured in vitro.At 4,8,12,24,48 h after cells had been seeded,the gene and protein expression of epidermal growth factor receptor (EGFR),fibroblast growth factor receptor (FGFR),transforming growth factor β1 receptor (TGF- β 1R),insulin-like growth factor-1 receptor (IGF-1 R) and vascular endothelial growth factor receptor (VEGFR) in prostate epithelial cells were tested by RT-PCR and immunohistochem-istry methods,respectively.Results The expression of mRNA and protein of EGFR,FGFR,IGF-1R,TGF- β1R,VEGFR were significantly increased in anoxic and normoxic prostate epithelial cells (P ＜ 0.01 ).At different time point,the expression of mRNA and protein of EGFR,FGFR,IGF-1R,TGF- β1R,VEGFR significantly higher in anoxic than those in normoxic prostate epithelial cells (P＜ 0.01 )besides 4 h EGFR mRNA,12 h EGFR protein,4 h IGF-1R mRNA,4 and 8 h IGF-1R protein,4 and 8 h TGF-β 1R mRNA,4 and 8 h TGF-β 1R protein,4 h VEGFR mRNA (P ＞ 0.05).Conclusion Anoxic prostate epithelial cell can up-regulate the expression of somatomedin-receptor.

Objective To assess the image quality of iterative model reconstruction algorithm (IMR) compared with hybrid iterative reconstruction algorithm (iDose4) for hypovascular hepatic metastases.Methods Medical history and pathological results of 33 cases with primary malignant tumor were retrospective analyzed.Follow-up with enhanced CT or enhanced MRI at more than 3 months confirmed hypovascular metastases in these patients.All patients underwent abdominal CT scanning and dynamic enhanced CT scanning.Portal vein phase of low dose scanning data were taken as the research object.According to the different tube currents and reconstruction algorithm,the images were divided into 4 groups.Group A included images with tube current of 175 mAs and IMR post-processing (17 cases).Group B included images with tube current of 175 mAs and iDose4 post-processing (17 cases).Group C included images with tube current of 125 mAs and IMR post-processing (16 cases).Group D included images with tube current of 125 mAs and iDose4 post-processing (16 cases).In the cases with multiple lesions,the largest lesion was selected to evaluate.For each image of the objective evaluation [including noise,the signal-to-noise ratio (SNR),contrast to noise ratio (CNR)] and subjective evaluation (including lesion sharpness,necrosis interface and diagnostic confidence).The CT dose index of each scanning was recorded.The objective evaluation,subjective evaluation indexes were compared by paired samples t test and Wilcoxon signed rank test.Results The tube current of Group A and Group B were (7.7± 1.8) and (12.8±3.7)HU,while CNR were 10.3 ±2.6 and 5.6± 1.4,SNR were 13.2±3.2 and 8.1 ± 2.2,and the differences were statistically significant (t values were 9.966,12.670,9.203;P＜0.01).The tube current of Group C and Group D were (7.2±1.3) and (9.9±1.8)HU,while CNR were 7.4±2.0 and 3.7±0.9,SNR were 13.9±2.9 and 9.8±1.9,and the differences were statistically significant (t values were 9.209,12.320,9.628;P＜0.01).The lesion sharpness score of Group A and Group B were 4.95±0.24 and 4.29±0.59,while the necrosis interface score were 4.76 ± 0.36 and 3.68 ± 0.30,diagnostic confidence score were 4.94± 0.24 and 4.44 ±0.56,and the differences were statistically significant (P＜0.05).The lesion sharpness score of Group C and Group D were 3.94±0.68 and 3.56±0.63,while the necrosis interface score were 3.91±0.64 and 3.03±0.50,diagnostic confidence score were 4.19±0.40 and 3.94±0.44,and the differences were statistically significant (P＜0.05).CTDIvol of 175 mAs group and 125 m As group were (11.83±0.28) and (8.44±0.24) mGy respectively.Conclusion Compared with iDose4,iterative reconstruction technology IMR significantly reduces the image noise and enhances image quality of hypovascular hepatic metastases.

?AIM: To evaluate the effects on recovering of corneal wound and postoperative discomfort of different methods for primary pterygium.?METHODS: Forty-seven cases ( 60 eyes ) of primary pterygium were excised under microscope with limbal epithelial transplantation, with sharp dissection ( 24 cases, 30 eyes, Group A) and blunt dissection (23 cases, 30 eyes, Group B).All cases were followed up for 1d to 1mo.?RESULTS: The recovering of corneal wound was better in Group B on 1st day and 3rd day after surgery.Pain, photophobia and tears, foreign body sensation were more serious in group A on 1st day after surgery with a statistically significant difference (P=0.005,0.015,0.012). Pain, photophobia and tears, foreign body sensation were more serious in Group A on 3rd day after surgery with a statistically significant difference ( P=0.019,0.018, 0.015).There was no statistically significant difference on 1wk and 1mo after surgery (P>0.05).? CONCLUSION: Compared with sharp dissection, primary pterygium excised with blunt dissection can significantly improve recovering of corneal wound and postoperative discomfort.

Objective To explore the immunophenotype of children with acute myeloid leukemia(AML) and its clinical significance.Methods Statistics was used to analyze the relationship between the immunophenotype of AML and their French-American-Britain(FAB) classification,complete remission (CR) in one month and 3-years event-free survival(EFS).Results CR rate was 71.6% and 3-years EFS rate was 50.8%. HLA-DR and CD34 absent mainly in M3, associated with higher CR and EFS rate. So did CD33 negative cases, especially in M2. CD13 positive was significantly predictive factor for achieving CR.Co-expression of lymphoid antigens and NK cell antigens(CD56) with M2 which correlated with lower CR and EFS rate.Conclusions The negative of HLA-DR, CD34, CD33,as well as CD13 positive, have relationship with good prognosis. Lymphoid antigens and CD56 are poor prognostic factors.

Objective To investigate the stability of immunophenotyping in the course of relapse or at treatment failure of patients with acute lymphoblastic leukemia(ALL) and that of immunophenotyping of positive minimal residual disease(MRD).Methods From Aug.2000 to Dec.2007,33 children with ALL who relapsed or treated failure were enrolled. These children were detected MRD by flow cytometry. The immunophenotyping of children who relapsed or treated failure were compared with that of initial therapy;the immunophenotyping of MRD relapsed was compared with that of initial therapy.Results 1.In 23 out of 27 cases (85.18%) with B-ALL,changed at least 1 antigen between diagnosis and relapse.Six children with CD45 down-modulation and 2 children with CD45 up-modulation.Two children with CD19 down-modulation and 1 child with CD19 up-modulation.Six children with CD34 down-modulation and 4 children with CD34 up-modulation. Five children with CD10 down-modulation and 7 children with CD10 up-modulation.2.Six children with T-ALL had the same expression in CD45 between relapse and treatment failure. 3.These were 15 children had the least 1 case MRD,25 cases MRD were detected,these was 1 case up-modulation in CD45,1 case down-modulation in CD19,2 cases up-modulation and 8 cases down-modulation in CD34,3 cases up-modulation and 6 cases down-modulation in CD10.Conclusions Immunophenotyping of children with ALL may change at relapse and treatment failure. The frequency of change in B-ALL is higher than that of in T-ALL,but the change can not impact the detection of MRD.
