Aim To investigate the effect of CD44 anti-body-A3 D8 on the expression of IL-3 Rα and down-stream PI3K/Akt in NB4 cells. Methods The ex-pression of IL-3 Rα mRNA was detected by real-time quantitative RT-PCR, the IL-3Rα protein expression and changes of PI3 K/Akt signal pathway in NB4 cells treated with A3D8 were analyzed by Western blot. An-nexin-V-FITC/PI double staining flow cytometry was u-tilized to detect the apoptotic cells. The inhibitor of PI3 K/Akt signaling LY294002 combined with A3 D8 was used to inhibit the PI3K/Akt in NB4 cells. Re-sults After treated with A3 D8 , both the transcription-al level and translational level of IL-3 Rα were remark-ably reduced, and the PI3K/Akt pathway was inhibi-ted. LY294002 improved the inhibitory and apoptotic effects of A3D8 on NB4 cells. Conclusion CD44 antibody A3 D8 can downregulate the expression of IL-3Rα and inhibit the downstream PI3K/Akt pathway.

Objective: To obtain phage-displayed ScFv library directly against prostate carcinoma cells, and select antibodies binding to prostate carcinoma cells specifically, so as to lay a foundation for developing diagnostic agents and clinical therapies of prostate carcinoma. Methods: Balb/c mice were immunized i. p . with purified membrane protein mixture of prostate carcinoma cells PC3, DU145. mRNA was isolated from the spleens of immunized mice, heavy and light chain genes ( VH and VL) of antibody were amplified separately by RT-PCR and assembled into ScFv gene with a specially constructed linker DNA. , the ScFv gene was ligated into the phagemid vector pCANTAB 5E and the ligated sample was transformed into competent E. coli TG1. The transformed cells were infected with M13K07 helper phage to yield recombinant phage. After five rounds of panning with PC3 cells, the positive clones were selected with the ELISA from the enriched phages. Results: A ScFv library of 3. 5 ? 106 was obtained and one phage-ScFv which can bind specifically PC3 cells was found. Conclusions: A prostate carcinoma specific antibody was identified , which paves a way for study of prostate carcinoma.

Objective To investigate the predictive value of spiral CT in composition changes of pediatric urinary.Methods A total of 25 pediatric patients with urinary stones were investigated.Eighteen patients with renal stones were stratified into two groups:an alkalization therapy alone group ( n =9 ) and a comprehensive therapy group (n =9).Flame atomic absorption spectrum (AAS) was employed to measure calcium level of the pediatric urinary stones.Spiral CT was employed to measure the peak CT number in vitro of all the pediatric urinary stones and 61 adult urinary stones,which served as controls.Results All pediatric urinary stones contained calcium ( 0.11％ - 26.30％ ).A positive correlation was observed between the CT number of pediatric urinary stone and its stone calcium level ( r =0.855,P ＜ 0.01 ).Compared to the alkalization therapy alone group,the CT number and stone calcium level of pediatricrenal stones in the comprehensive therapy group were significant higher (stone CT number:162 ± 60 HU VS.783 ±476 HU,P ＜ 0.01 ; stone calcium level:1.30 ± 1.52％ VS 19.83 ± 7.48％,P ＜ 0.01 ).Compared to ≤400 HU pediatric renal stones,＞ 400 HU renal stones contained more calcium (21.71 ± 5.27％,1.65 ±1.82％,P ＜ 0.01 ) and failed to dissolve by alkalization therapy alone ( x2 =11.455,P ＜ 0.01 ).Conclusions CT could be a predictive tool for composition changes of pediatric urinary stones.In clinical CT scanning setting,＞400 HU pediatric urinary stones probably will contain more calcium and not be suitable for alkalization therapy alone.

Objective To investigate the mouse liver blood vessel images using phase contrast X-ray imaging with synchrotron radiation. Methods 6 female C57BL/6 mice were randomly divided into two groups, 3 mice in each group. In one group, livers excised after hgated arteries, veins and common bile duct. In another group, iodine infused via the portal vein and drained from inferior vena cave until all the blood in the portal veins and hepatic veins was displaced. After infusion, arteries, veins and common bile duct were ligated and livers were excised. Results Blood vessel images were clearly produced by diffraction enhanced imaging. This method can discriminate vessels down to about 40 μm in diameter without contrast agent. Using a contrasting agent more details could be produced. In one liver lobe, the entire branch of the portal vein could be clearly produced by one by one phase contrast image from the main axial blood vessels of liver lobe to the nine generation of branching. Conclusions Phase contrast imaging has the advantage of good contrast and high spatial resolution.

Objective To investigate the correlation between retraction phenomenon on the coronal planes obtained by an automated breast volume scanner ABVS and biological behaviors of breast cancer Methods Two hundred and eighty-eight female patients with 293 pathologically proven breast cancers were included in this study All of them underwent ABVS examinations before surgery Retraction phenomenon on the coronal planes was evaluated retrospectively Correlation between retraction phenomenon and hormone receptor HR human epidermal growth factor receptor 2 HER-2 Ki-67 molecular subtypes histologic type histologic grade lymph node status lesion size and patient age were evaluated by univariate logistic regression analysis Above significant variables were then enrolled in multivariate logistic regression analysis to select independent risk factors for retraction phenomenon Results By univariate logistic regression analysis Luminal A subtype odds radio OR =8 395 P <0 001 HR positive OR=4 876 P <0 001 HER-2 negative OR = 4 407 P < 0 001 lower expression of Ki-67 OR = 3 716 P <0 001 lower grade OR=3 574 P <0 001 lymph node invasion OR=2 053 P =0 004 and smaller lesion OR=1 762 P =0 033 were risk factors for retraction phenomenon while histologic type P =0 3 1 8 and patient age P = 0 612 were not By multivariate logistic regression analysis Luminal A subtype OR=9 877 P <0 001 lower grade OR=3 573 P <0 001 and lymph node invasion OR=2 730 P = 0 004 were independent risk factors for retraction phenomenon among which Luminal A subtype was the strongest one Conclusions Retraction phenomenon on the coronal planes obtained by ABVS is closely related with Luminal A subtype and may be an imaging feature of less aggressive behaviors of breast cancer.

Objective To observe the expression of vimentin (Vim) after silence of interleukin-1β (IL-1β) in rats with spinal cord contusion (SCC). Methods The model of SCC was established in 30 Sprague-Dawley rats with Allen's method. The rats were randomized into vector group (n=15) and silence group (n=15), which were injected blank lentivirus vector and vector of IL-1β siRNA, respectively; and divided in three, seven and 28 days subgroups. The relationship between IL-1βand Vim was predicted with GeneMANIA bioinformatics. The expression of Vim protein and mRNA in spinal cord was detected with immunohistochemistry and real-time quantitative polymerase chain reaction. Results GeneMANIA bioinformatic analysis indicated that there was some direct and indirect relationship between IL-1β and Vim. The Vim protein and mRNA expressed in the spinal cord, and was less in the silence group than in the vector group (t>2.875, P<0.05). Conclusion Silence of IL-1β can inhibit the expression of Vim in SCC rats, which may promote the recovery of spinal cord function.

OBJECTIVE: To study the correlation of dynamic change in serum 25-hydroxy vitamin D [25(OH)D] level with the disease severity and related laboratory markers in infants/toddlers with severe pneumonia. METHODS: A total of 132 infants/toddlers with severe pneumonia who were hospitalized between March 2017 and March 2018 were enrolled as the severe pneumonia group. According to the disease severity on admission and after one week of treatment, they were further divided into non-critical group (41 children on admission and 78 after one week of treatment), critical group (59 children on admission and 35 after one week of treatment), and extremely critical group (32 children on admission and 19 after one week of treatment). A total of 142 infants/toddlers who underwent physical examination during the same period of time were enrolled as the healthy control group. The serum levels of 25(OH)D, procalcitonin (PCT), and N-terminal pro-brain natriuretic peptide (NT-proBNP) were measured on admission and after one week of treatment for the severe pneumonia group, and the serum level of 25(OH)D was measured on admission for the healthy control group. According to the 25(OH)D level after one week of treatment, the children with severe pneumonia were divided into increased vitamin D (VD) group with 81 children and reduced VD group with 51 children, and a comparative analysis and a correlation analysis were performed. RESULTS: The severe pneumonia group had a significantly lower mean 25(OH)D level than the healthy control group (P<0.05), and all the three subgroups of different severities had significantly lower 25(OH)D level than the healthy control group (P<0.05). On admission and after one week of treatment, the non-critical group had a significantly higher 25(OH)D level than the critical and extremely critical groups (P<0.01), and the critical group had a significantly higher 25(OH)D level than the extremely critical group (P<0.05). The extremely critical and critical groups had significantly higher serum levels of PCT and NT-proBNP than the non-critical group on admission and after one week of treatment (P<0.05). After one week of treatment, compared with the reduced VD group, the increased VD group had a significantly less serious condition. At discharge, the increased VD group had a significantly better outcome compared with the reduced VD group (P<0.01). In the children with severe pneumonia, the change value of serum 25(OH)D level after treatment was negatively correlated with the change values of PCT and NT-proBNP (r=-0.597 and -0.404 respectively; P<0.01). CONCLUSIONS The change in VD level is correlated with the severity of severe pneumonia in infants/toddlers and can be used as an index for disease monitoring. VD supplementation may help with disease recovery.
