Objective To investigate the early comprehensive intervention on neonatal hypoxic ischemic encephalopathy (HIE) effects and the biological mechanisms.Methods 120 cases of HIE were randomly divided into intervention group and control group.Under the basis of drug treatment,the intervention group were given the different perceptual stimuli,audiovisual stimulation,active and passive limb training early comprehensive intervention,the control group only to normal drug treatment.The mental development index(MDI) and psychomotor develo pmental index (PDI) were applied after 3,6,12,and 18 months.S100B protein levels were detected using enzyme immunoassay.Results MDI score in the intervention group with HIE,from the beginning of the 12 month,was higher than that in the control group,there was significant differences (12th month:(96.6±9.4)vs (86.8±9.5),P<0.01).PDI score from the beginning of the 6 month,was higher in the intervention group with HIE than that in the control group,there were significant differences (6th month:(91.6±9.2)vs (82.2±11.0),P<0.01).Serum S100B protein level has a tendency to fall for all HIE patients with the old growth.Born in two groups of serum S100B protein levels were higher in neonate period,but there was no difference(P>0.05).From the beginning of the 3rd month,serum S100B protein levels in the intervention group were reduced significandy,compared with the control group at each time point level(3rd month:(1.29±0.15)ng/L vs(1.40±0.14)ns/L;6th month:(1.06±0.21)ng/L vs(1.26±0.22)ng/L,P<0.01).Conclusion Early intervention can improve the mental and motor development of children with HIE,and serum S100B protein is involved in the mechanisms.

Objective To investigate the changes of collagen types Ⅰ and Ⅲ, the effects of Oleum Curcumae Aromaticae oil injection on injuried rat arteries and collagen types Ⅰ and Ⅲ after balloon angioplasty Methods The left common carotid artery in rats was denuded with a balloon catheter The rats were killed 14 days after injury Cross sections stained with picrosirius red from the injuried segments were processed for distribution, arrangememt, amount, proportion of collagen type Ⅰ and type Ⅲ by polarizing microscope, and those stained with hematoxylin eosin for histological and morphological changes studied by computer assisted picture analysis system Results Fourteen days after balloon injury, collagen type Ⅰ and type Ⅲ of the model group were found mainly in adventitia, much more, thicker, brighter and more disordered than those of the sham operation group Compared with the model group, collagen type Ⅰ and type Ⅲ of the E Zhu You group were found mainly in adventitia, less, thinner, dimmer and more orderly Lumen area, EEL perimeter, IEL perimeter of the model group were decreased and the areas of collagen types Ⅰ and Ⅲ increased more significantly than those of the sham operation group Compared with the model group, maximal intimal thickness, neointima area, the areas of collagen type Ⅰ and Ⅲ of the E Zhu You group were decreased significantly which was not different from those of the sham operation group Lumen area, EEL perimeter and IEL perimeter were increased markedly up to those of the sham operation group The ratio of collagen subtypes Ⅰ/Ⅲ was not significantly different between the two of the three groups Conclusion The accumulation and derangement of collagen types Ⅰ and Ⅲ may be more important in restenosis than the ratio of collagen subtypes Ⅰ/Ⅲ We concluded that Oleum Curcumae Aromaticae oil injection inhibits neointimal formation and vascular remodeling after arterial injury by mechanisms involving collagen types Ⅰ and Ⅲ production and their arrangement

OBJECTIVE:To establish a method for the identification and content determination of leguminosae in Qizhu bishi granules. METHODS:Thin layer chromatography (TLC) was used to identify the leguminosae. HPLC-ELSD was used to deter-mine the content of astragaloside A in leguminosae. The column was Diamonsil C18 with the mobile phase of acetonitrile-water(32∶68,V/V)at the flow rate of 1.0 ml/min,the column temperature was 40 ℃. The sample size was 20 μl. The drift tube temperature was 108 ℃ with the nitrogen gas flow rate of 2.8 ml/min. RESULTS:The TLC features of leguminosae were obvious with clear spots and good specificity. Astragaloside A had a good linear relationship in the range of 0.402 4-4.02 μg(r=0.997 0). RSDs of pre-cision,stability and reproducibility tests were≤0.8%. The average recovery was 99.00%(RSD=1.29%,n=9). CONCLUSIONS:The method is simple,accurate and reliable and can be used for the quality control of Qizhu bishi granules.

BACKGROUND:Mesenchymal stem cel s (MSCs) can be differentiated into vascular endothelial cel s to construct ideal blood vessel grafts in vitro that have wide prospective utility in the clinical treatment of ischemic diseases, vascular engineering and regeneration medicine.
OBJECTIVE:To review the recent research progress and related issue in biological characteristics of MSCs as wel as differentiation of MSCs isolated from different sources into vascular endothelial cel s.
METHODS:The first authors retrieved PubMed, Sciencedirect and Medline databases for relevant articles published from January 2000 to June 2015. The key words were“mesenchymal stem cel s;vascular endothelial cel;cel differentiation”in English. Initial y, 156 articles were retrieved, and final y 51 articles were included in result analysis.
RESULTS AND CONCLUSION:The MSCs sources are abundant. The research about bone marrow-derived MSCs is the earliest and maximum, but with the increasing donor age, their proliferation and differentiation ability decreases. MSCs from umbilical cord, placenta and amniotic membrane are easy to obtain, and meanwhile both neonatal and maternal does not feel any pain and psychological burden. Given these, these cel s are more acceptable for recipients, and there are no ethical, moral and legal disputes. MSCs from the umbilical cord blood are abundant with weak cel immunogenicity and low viral and bacterial contamination probability. However, the clinical application of amniotic fluid marrow-derived MSCs is limited because of its sampling methods.
