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 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 study the effect of bioactive glass (BG) on the dentin bond strength and the microleakage of hybrid layer. METHODS: In the study, 30 dentin planes were prepared from the third molars with no caries and equally assigned to the control group, BG group, and sodium trimetaphosphate (STMP)-polyacrylic acid (PAA)-BG group (S-P-BG group), randomly. After etched with 35% phosphoric acid, the dentin planes of BG group were pretreated with 0.5 g/L BG, and the dentin planes of S-P-BG group were pretreated with 5% STMP, 5% PAA and 0.5 g/L BG. No additional pretreatment was done to the dentin planes of control group. Then the dentin planes were bonded using 3M Single Bond 2 adhesive to 3M Z350XT composite resin, and cut into 0.9 mm×0.9 mm column samples, which were stored at 37 ℃ artificial saliva (AS). After 24 hours, 1 month, and 3 months, the microtensile bond strength test was performed. The data were analyzed using one-way ANOVA and LSD method. The morphology of the bond fracture interface was observed with scanning electron microscope. Other 27 teeth were collected and the enamel layer and roots cut off, with the pulp chamber exposed. 0.1% rhodamine B was added to the 3M Single Bond 2 adhesive, and then the adhesive was applied to complete the bonding procedures as above. The teeth were stored in 37 ℃ AS for 24 hours, 1 month, 3 months, and then 0.1% sodium fluorescein solution was placed in the chambers and stained for 1 hour. Confocal laser scanning microscopy was used to observe the interface morphology and microleakage of the hybrid layer. RESULTS: At the end of 24 hours and 1 month, there was no significant difference in the microtensile bond strength among the three groups (P>0.05). After 3 months of soaking, the S-P-BG group [(36.91±7.07) MPa] had significantly higher microtensile bond strength than the control group [(32.73±8.06) MPa] (P=0.026); For the control group and the BG group, the microtensile bond strength significantly decreased at the end of 3 months compared with 24 hours (control group: P=0.017, BG group: P=0.01); The microtensile bond strength of S-P-BG group af the end of 3 months had no significant difference in compared with 24 hours [(37.99±7.98) MPa] (P>0.05). Observation of the fracture surface at the 24 hours showed no obvious mineralization in all the three groups. After 1 and 3 months, mineral formation was observed in BG group and S-P-BG group, and no obvious collagen exposure was observed in S-P-BG group. Confocal laser scanning microscopy revealed no obvious differences in the morphology and quantity of the resin tag in the control group, BG group and S-P-BG group. At the end of 24 hours, leakage was found in all the three groups. The microleakage of the control group increased at the end of 3 months, while the microleakage of the BG and S-P-BG groups decreased. CONCLUSION BG pretreatment of dentin bonding interface can induce mineralization at the bonding interface and reduce the microleakage of the hybrid layer; pretreating the dentin bonding interface with STMP, PAA and BG may enhance the maintaining of the dentin bonding durability.
