Activated protein C(APC)is generated through hydrolysis of protein C by thrombin-thrombomodulin complex.APC has been proved to play different roles in many human diseases,such as anticoagulant,antiinflammatory,profibr-inolysis,antiapoptotic and endothelial cytoprotective activities.In this review,the research progress of the functions of APC and related diseases,especially the neural protective roles of APC in central nervous system were summarized.

0.05).(3)The levels of CRH and DHEA-S in umbilical cord blood of PL(7.8?3.3)ng/L,and(514?295)?g/L,respectively and of TL (7.7?4.1)ng/L,and(483?207)?g/L,were higher than that in term not in labor(4.8?2.4)ng/L, and(360?80)?g/L,respectively(P 0.05).In PL,the level of CRH in umbilical cord blood and the expression of CRH mRNA in placentas and fetal membranes were correlated with each other(r=0.935 and 0.853,P

This paper mainly discusses how physician - patient disputes are included within scope of the media and become its"focus"of concern.It has revealed in my research that the dual interests of the media,the interests driving of the journalists,the strength of TV (or video) and the audiences are the inherent dynamisms which ehance the media let physician - patient disputes included in its vision.In other words,the physician - patient disputes become the"hot spot"of media attention with the help of the gatekeepers and the audiences.

AIM　To analyse the essential oil components of Thymus quinquecostatus Celak. METHODS　Gas chromatography/mass spectrometry were used. RESULTS　A total of 78 components were separated. 34 of them were identified, which accounted for 95.93% of the total peak area. The main constituents are o-cymene, carvacrol, caryophyllene, 2-isopropyl-1-methoxy-4-methylbenzene and γ-terpene. CONCLUSION　Thymus quinquecostatus Celak has perfume and medical development value.

0.05); ⑵Serum TNF? and IL-6 levels in kansui root group were significantly lower than those in control group at the third, 7th and 14th days after treatment(P0.05). Conclusion ⑴kansui root therapy was effective for SAP, ⑵kansui root therapy ameliorated SAP possibly by decreasing the levels of serum TNF? and IL-6, ⑶kansui root therapy improved microcirculation of pancreas possibly by decreasing the ratio of TXA 2/PGI 2, and ⑷kansui root treating SAP may be multi-pathway and multi-target.

Objective To investigate the ultrasound characteristics of prenatal fetus otocephaly . Methods Three prenatal fetus with otocephaly were examined with two -and three-dimensional ultrasoundand examined results were compared with the those of induced labor or autopsy ,and ultrasound characteristicsof prenatal fetus were analyzed and summarized .Results The ultrasound performance of three prenatal fetuswith otocephaly and the examination of the appearance after induced labor showed :(1) The most intuitiveinitial sonographic performance of otocephaly was manifested by the absence of stomach bubble andoverabundance of amniotic fluid.Among three fetus,one fetus had overabundance of amniotic fluid at the midstageof pregnancy,one fetus had normal amniotic fluid at the mid-stage of pregnancy and one fetus hadextremely high amount of amniotic fluid and absence of stomach bubble at late stage of pregnancy .(2) Allthree fetus showed agnathy and synotia (shifts of both ears to the midline) and microstomia deformity.(3) All three fetus had associated complications with deformity in other systems including two cases of patients withcleft lip and palat,both were the fracture unilateral cleft lip derived from small mouth .One fetus withdysmelia and one fetus with complicated cardiovascular deformity and situs inversus and .(4) The results ofexamination after induced labor or autopsy were consistent with those of the prenatal ultrasound examination . Conclusions Prenatal ultrasound examination is an effective and feasible means for the diagnoses ofotocephaly.When the symptoms of “absence of stomach bubble and extremely high amount of amniotic fluid ”occurred,the fetal ear and submaxilla should be examined to confirm stand -alone otocephaly prenatally.

Objective To investigate the roles of adrenomedullin(ADM) and endothelin-1(ET-1) in left-to-right shunt congenital heart disease(CHD) complicated with congestive heart failure(CHF).Methods Plasma ADM and ET-1 concentrations were measured by radioimmunoassay in heart failure stage and recovery period of 18 infants with left-to-right shunt CHD.Also 20 healthy infants acted as control group were measured.Results Plasma concentrations of ADM and EF-1 were significantly higher in heart failure stage of left-to-right CHD infants than those in their recovery period,and both in their heart failure stage and in their recovery period were higher than that in control group(P

Objective To assess the wall elasticity of the common carotid artery using echo-tracking in healthy children and children with hyperlipidemia.Methods The study included 68 normal healthy children and 25 children with hyperlipidemia.All the subjects were 3-18 years old.They were divided into three groups according to ages 3-6 years old group,7-13 years old group and 14-18 years old group.Echo-tracking was used to measure the pressure-strain elastic modulus (E?),stiffness parameter(?)and arterial compliance (AC) of the common carotid artery.Results The average values of E? were different among the three age groups in normal healthy children (all P

Human protein tyrosine phosphatase β (HPTPβ) is an endothelial cell-specific receptor protein tyrosine phosphatase(PTP). HPTPβ plays an important role in regulating pathophysiological processes such as angiogenesis and cell-to-cell adherens junction, and is taken as a novel target for developing new antiatherosclerosis and antitumor drugs. In this review, the latest research progress in the structure, physiological functions and small molecular inhibitors of HPTPβ is summarized.

Objective:A novel tuberculosis DNA vaccine integrating siRNA,fusional antigen and hIL-12 triple expression units was constructed in our laboratory.Methods:To evaluate the independent expression of the three expression units,two eukaryotic expression plasmid pVAX1-siRNA-PVAE[EGFP]-hIL12 with TB fusional gene Ag85B-ESAT6(PVAE) and enhanced green fluorescent protein(EGFP),and pVAX1-siEGFP-PVAE[EGFP]-hIL12 with siRNA coding sequence targeting EGFP instead of Mcl-1L were constructed.Then two plasmids were used to transfer human embryonic kidney 293 cells.Based on EGFP report gene,it was demonstrated that siRNA expression unit and fusional antigen gene were independently expressed.Results:The hIL12 expression at 48h and 72h post transfection were also detected by ELISA analysis up to 1571.63pg/ml and 2392.25pg/ml respectively in the cell culture fluid.Conclusion:The results demonstrated that the novel DNA vaccine with siRNA,TB fusional antigen and hIL12 three expression units in the same plasmid frame is successfully constructed and independently expressed in eukaryotic cells.It laid a foundation for further animal model study on anti-tuberculosis effects of this novel DNA vaccine.
