Objective To compare the influence of hypothyroid function in neonatal with hyperbilirubinemia by two kinds blue-light treatment way.Methods 36 cases were divided into the Bilibed infant blue light the bed treatment in 18 cases(group A) and the traditional warm box with the both blue light treatment in 18 cases(group B).The influence of hypothyroid function in neonatal with hyperbilirubinemia were observed after treatment and before treatment.Results The contents of bilirubin in two group after treatment were obviously lower than that before treatment(P0.05).Conclusion The therapeutic of Bilibed method can get the better therapeutic effect than the traditional warm box with the both blue light treatment for the neonatal with hyperbilirubinemia.The change of thyroid function was no influence.

Objective To observe the role of short-term use of megestrol acetate in reducing the toxicity of chemotherapy in breast cancer and in improving the quality of life of patients, as well as its impact on neo-adjuvant chemotherapy effects. Methods The effection of adjuvant chemotherapy, toxicity, and the quality of life of 158 patients with breast cancer were investigated by a retrospective control study. The data were statistically analysized by X~2 test. Results There was no significant difference of neo-adjuvant chemotherapy effects between Megestrol acetate + CEF chemotherapy group and vitamin C + CEF chemotherapy group (Megestrol acetate + CEF chemotherapy group was 74. 84%, vitamin C + CEF chemotherapy group was 76.15) ; Megestrol acetate + CEF chemotherapy group had more modest bone marrow suppression and gas-trointestinal reactions and better food intake, weight, KPS score than vitamin C + CEF Chemotherapy group, all the differences being statistically significant (P < 0.05). Conclusion Short-term use of megestrol ace-tate can reduce the adverse effects derived from chemotherapy of breast cancer and improve the quality of life of patients with breast cancer and had no effects on the efficacy of the neo-adjuvant chemotherapy.

Objective The micro-vascular element plays a key role in the delivery of nutrients and the regulation of hemodynamic behavior, however, research is often hindered by ethical , economic and technological issues .Therefore, construction of a micro-vascular network in vitro will help to study the related pathological and physiological behavior in microvessels.Methods In this study, a micro-vascular element model with features of a micro-vascular network in vivo was designed based on the network structure of retinal arterioles .A micro-vascular network model in vitro, characterized by network asymmetry and the presence of both bifurcation-and side-branches , was developed by soft lithography technology . The developed microdevice allowed for the quantification of the cell -depletion layer ( CDL) thickness and hematocrit ( Ht) distribution within the microchannel networks .Results and Conclusion The study showed the potential of the developed in vitro model in revealing key hemodynamic features which have been detected for microvascular elements in vivo, including the relationships between CDL thickness , Ht and red blood cell distribution .The present study provides a new strategy and a technology for studying hemodynamics and microvascular system diseases in vitro.

Objective To research the effects of puerarin on Alzheimer′s disease(AD) rats spatial learning and memory dis‐order induced by Aβ1‐42 .Methods Bilateral hippocampal injection of Aβ1‐42 was used to induced AD model rats .All rats under‐went gavage administration with puerarin with different dose for 28 d since the 3rd day after the construction of model ;and the Morris water maze was used to test the spatial learning and memory ability of rats .Results The model group rats showed obvious learning and memory disorder ,and the ability of learning and memory disorder of rats in the high ,medium and low dose of puerarin interven‐tion group were significantly improved .Conclusion Puerarin can improve the spatial learning and memory ability of AD model rats .

Objective To observe the effects of icarisid Ⅱ (ICS Ⅱ)on cognitive deficits and expression of synaptophysin(SYN)in chronic cerebral hypoperfusion(CCH)rat models.Methods 40 male SD rats were randomly divided into four groups:normal group,sham operation group,model group and ICSⅡgroup.The model was established by permanent bilateral common carotid artery occlusion(BCCAO).ICS Ⅱ group was administered ICS Ⅱ at a dose of 8mg·kg -1 ·d -1 by gavage on 1st day after modeling.Sham group and CCH group were injected double -distilled water.The escape latency(s)and spatial probe times were measured by water maze test.Then,the morphology change and expression of SYN in hippocampal were assayed by HE and immunohistochemistry analysis.Results At the 1st month and 2nd month,the escape latency in the model group[(40.02 ±4.95)s,(42.29 ±5.75)s]were significantly prolonged compared with the sham operation group[(26.43 ±2.68)s,(26.84 ±2.06)s](t =4.89,5.06,all P <0.05).And those in the ICS Ⅱ group[(30.58 ±3.03)s,(29.19 ±4.23)s]were significantly decreased compared with the model group(t =3.63,4.10,all P <0.05).The space probe times in the model group[(2.6 ±0.89)times, (2.40 ±1.14)times]were significantly reduced compared with the sham operation group[(6.00 ±2.16)times, (5.75 ±2.16)times](t =3.23,4.18,P <0.05).And those in the ICS Ⅱ group[(4.40 ±1.34)times,(5.00 ± 1.58)times]were significantly increased compared with the model group (t =2.49,2.98,all P <0.05).The average optical density of SYN in hippocampal in the model group[CA1:(0.121 ±0.009),(0.122 ±0.008);CA3:(0.172 ± 0.028),(0.173 ±0.021 )]were significantly reduced compared with the sham operation group[CA1:(0.131 ± 0.006),(0.136 ±0.007);CA3:(0.218 ±0.035),(0.204 ±0.018)](t =2.43,2.53,3.12,2.34,P <0.05). Those in the ICS Ⅱ group[CA1:(0.131 ±0.006),(0.132 ±0.006);(0.212 ±0.02),(0.208 ±0.022)]were significantly increased compared with model group(t =2.41,2.41,2.31,2.77,all P <0.05).However,there was no statistically significant difference of those index between the normal group and sham operation group(P >0.05 ). Conclusion ICS Ⅱ can improve the cognitive deficits in CCH rat models and this effect may be associated with increased expressions of SYN in hippocampal.
