Combined with the deficiencies of management of medical consumable materials in supply chain and high-value materials, the application of ERP to workflow, fundamental material, operation and high-value material management are explored. It indicates that although with some deficiencies, this ERP system optimizes business process and then improves work efficiency of management of medical consumable materials greatly.

Objective To detect the fetal external ear observation on standard sections and the best time with ultrasonography. Methods Total 2212 normal fetuses 17-40 weeks of gestation were divided into six groups. Fetal ears were obtained on transverse-incline view at cervical vertebra level (section A) and mandible level (section B), on parasagittal view (section C) and coronal view (section D) at external ear level. Fetal ears were evaluated and analyzed statistically. Results Among 2212 normal fetuses, 3454 ears (78.07%), 1694 ears (38.29%), 3454 ears (78.07%) and 2304 ears (52.08%) were obtained on section A, B, C and D, respectively. The obtained-rate of fetal ears on section A was the same as section C at the same week of gestation, but was significant higher than that of section B and section D (P<0.05). The obtained-rate of fetal ears was statistical different between section B and section D at the groups of 25-40 weeks (P<0.01). The obtained-rate of fetal ears was negatively correlated with gestational age (P<0.01). Conclusion It is useful and easy to observe the fetal external ear with ultrasonography to detect fetal ear abnormalities. Section A and section C are recommended to be standard observation sections for fetal external ear. Section B and section D can be used as supplementary for section A and section C. The best time for fetal external ear observation with ultrasonography is 17-24+6 weeks gestation.

AIM:There is little evidence proving the molecular mechanism of WenxinKeli ( WXKL) .This study tried to explore the gene ex-pression profile and pathology alteration of WXKL-treated rabbits with myocardial infarction .METHOD: Twenty male adult rabbits were randomly divided into 4 groups:sham, model, WXKL and captopril groups .Model, WXKL and captopril groups underwent the ligation of the left anterior descending coronary artery , while sham group went through an identical procedure without ligation .WXKL (817 mg? kg-1? d-1), captopril (8 mg? kg -1? d-1) and distilled water (model and sham) were administered orally to the rabbits. 4 weeks later, hearts were taken out for expression chip and pathological staining (HE, Masson and TUNEL) after echocardiography. RESULT:WXKL could down-regulate genes associated with inflammation (CX3CR1, MRC1, and FPR1), apoptosis (cathepsin C and TTC5) and neuro-hormonal system (ACE and EDN1), and up-regulate angiogenesis promoting gene like RSPO 3, which explained why WXKL group represented with better cardiac function , less histopathological injury and slighter apoptosis .CONCLUSION:WXKL plays an important role in suppressing inflammation , inhibiting renin-angiotensin system and alleviating apoptosis , and might be a promising Chinese medicine in treating patients with myocardial infarction .

Objective To investigate the dynamic level changes and significance of triggering receptor expressed on myeloid cells-1 (TREM-1) in the injury brain tissues of rats caused by pneumolysin (PLY).Methods Sixty-four SD rats were randomly and equally divided into PLY group and control group,0.1 mL PLY and isopyknic normal saline was given through left internal carotid artery respectively.Brain tissue gross and histological changes were observed at different time(4 h,6 h,12 h,24 h),meanwhile the expression levels of neurocyte damage marker glial fibrillary acidic protein (GFAP) and neuron-specific enolase (NSE) protein were detected by immunohistochemistry;and the expression levels of TREM-1,tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) were detected respectively by enzyme-linked immunosorbent assay.Results The observation of brain tissue gross and histological changes indicated the existence of brain injury,and the expression levels of GFAP,NSE,TNF-α and IL-6 protein increased from 4 h after PLY were injected and augmented dynamically as time went on,compared with the control group at corresponding time points,the differences were statistically significant (all P ＜ 0.05).The level of TREM-1 in the PLY group reached a peak at the 4 h time point,but decreased somewhat at the 6 h time point,the level of TREM-1 was still higher than that in control group,the differences were statistically significant(all P ＜ 0.05).However,the level of TREM-1 in the PLY group declined obviously at 12 h and 24 h time points,compared with that in control group,there were no significant differences (all P ＞ 0.05).Conclusions The expression levels of TREM-1 up-regulated obviously in the early stage of brain damage induced by PLY,which might be involved in the pathological process of brain damage by promoting the expression of TNF-α and IL-6.

Objective To establish a rapid method for the isolation of murine peritoneal macrophages. Methods Abdominal lavage was performed with NS and the peritoneal macrophages was purified from the lavage,which was later transferred into high glucose DMEM cul-ture medium. Cell viability was measured via the typan blue staining. Purity was observed via Wright's stain. Results High purity macropha-ges with typical morphology were obtained. Conclusion A simple and realistic method was set up for the isolation of murine peritoneal mac-rophages.

Objective To observe the biological role and the underlying mechanisms of miR-132 in liver cancer on invasion and metastasis.Methods Real-time quantitative polymerase chain reaction (RT-qPCR) analysis was used to examine the expression of miR-132 in four liver cancer cell lines (MHCC97H,HCCLYH,MHCC97L and SMMC-7721),a normal liver cell line HL-7702,and in liver tumor tissues with or without metastases.The biological effects of miR-132 transfection on human liver can-cer cells were assessed by wound assay,matrigel counting and in vivo experiments in nude mice.Western blotting was used to detect the expression of E-cadherin,α-cadherin,vimentin,fibronectin and ZEB2 in li-ver cancer cells.Immunohistochemistry was used to detect positive expression of ZEB2 in xenograft tumors.Results The expressions of miR-132 were downregulated in the four liver cancer cell lines when compared with the normal liver cell line (P ＜ 0.05),and in the liver cancer tissues with distant metastases when compared with the tissues without metastases (P ＜ 0.05).After transfection,ectopic expressions of miR-132 markedly inhibited cell migration and invasion in liver cancer cells.When compared with the control group,the expressions of E-cadherin and α-cadherin in the miR-132 transfection group were significantly increased,but the expressions of vimentin,fibronectin and ZEB2 were decreased.In addition,the numbers of metastatic lung lesions in nude mice in the miR-132 transfection group was markedly decreased when compared with the control group.The expressions of ZEB2 in the miR-132 transfection group was also significantly decreased when compared with the control group.Conclusions Transfection of miR-132 effectively inhibited invasion and metastasis of liver cancer cells in vitro and in vivo.miR-132 may become a new target for regulation of gene expression in liver cancer.
