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 investigate the induction of tolerant dendritic cells(DOs)and its mechanism in mice.Methods The dendritic cell line derived from C57BL/6 mouse.DO2.4 cells were co-cultured with TGF-?_1(20 ng/ml)to induce the tolerant DCs(TGF?-DC)and stimulated wihh li- popolysaccharide(LPS)for 48 h to induce the mature DCs(LPS-DC).Special small interference RNA molecule(siRNA)of PIR-B was chemically synthesized and was transfected into TGF?-DC by lip2000 (si-DC).The expression of paired immunoglobin receptor A/B(PIR-A/B)in DC2.4 cells was mea- sured by semi-quantitative RT-PCR and flow cytometry(FCM).The allogeneic stimulating capacity of DCs was measured by mixed lymphocyte reaction(MLR)using ~3H-thymidine incorporation test with the Balb/c spleen cells as reaction cells.The concentration of IFN-?in supernatants of MLR from dis- tinct groups was tested by enzyme linked immunosorbent assay(ELISA).Results TGF-?_1 up-regula- ted the PIR-B mRNA expression and down-regulated the PIR-A mRNA expression(P

Objective To investigate the temporal expression patterns of the related transcription factors and target genes in cardiomyocyte hypertrophy,and provide valuable clues for further researches on cardiomyocyte hypertrophy.Methods Isoproterenol (ISO) was used to induce ventricular myocytes hypertrophy in neonatal mice.The survival rate of cardiomyocyte was detected by CCK-8,and the average diameters and surface areas of cells were measured by computer photograph analysis system.The mRNA and protein expression levels of related genes were respectively measured by RT-PCR and Western blotting.Results The model of cardiomyocyte hypertrophy stimulated by ISO was constructed successfully.The expression levels of GATA4,MEF2C,GATA5,BNP and ANP increased 24 hours after ISO treatment,the expression levels of P300,α-MHC and TBX5 increased 12 hours after ISO treatment,and of SRF and β-MHC mRNA increased 6 hours after ISO treatment (P＜0.05).The expression levels of GATA4,α-MHC,β-MHC,SRF and P300 mRNA increased firstly,and then decreased in cardiomyocytes induced by ISO.The expression levels of GATA4,SRF,α-MHC,β-MHC and P300 mRNA were still higher than normal (P＜0.05),but of MEF2C decreased to normal (P＞0.0S) 72 hours after ISO treatment.The expression levels continuously elevated of GATA5,TBX5,ANP and BNP mRNA than that of controls (P＜0.05),while no fluctuation was found in NKX2.5 mRNA expression (P＞0.05).The expression of GATA4 protein increased,while of HEY2 protein decreased 48 hours after ISO treatment (P＜0.05).Conclusions In hypertrophic cardiomyocytes,the expression pattern of MEF2C is similar to,but the patterns of GATA5,GATA4,TBX5 and SRF are different with that in the development of heart,implying these genes are important during the process from compensatory stage to decompensation stage.The expression patterns of GATA4,MEF2C and SRF are similar to that of acetylase P300,implying the temporal expressions could be regulated by P300 in cardiomyocyte hypertrophy.
