Objective To explore change of RBC[Ca2+]i levels in neonates with hypoxic-ischemic encephalopathy(HIE)and the influence of nimodipine on RBC[Ca2+]i and its clinical significance.Methods Fifty-eight neonates with moderate and severe HIE were randomly divided into 2 groups including routine treatment group(n=28)and nimodipine group(n=30),and 20 healthy full-term neonates were selected as healthy control group.Based on the routine treatment,nimodipine[2 mg,0.5-1.0 ?g/(kg?min)] was given intravenously in the nimodipine group for 7-10 days.Blood samples were collected before and after treatment for 72 hours and 10-14 days,respectively.The levels of RBC[Ca2+]i were measured by Fura-2 pentakis(acetoxymethyl)ester[Fura-2/AM].The results were analyzed by SPSS 10.0 software.Results 1.The levels of RBC[Ca2+]i in neonates with HIE were significantly higher than those in healthy control group[(2.83?0.36)mmol/L vs(2.15?0.18)mmol/L,P

Objective:To establish an HPLC method to determine vanillin in 18 dairy products. Methods:The samples were sep-arated on a C18 column (250 mm × 4. 6 mm, 5 μm) with the mobile phase of methanol and water (35∶65) at the flow rate of 1. 0 ml ·min-1 . The detection wavelength was 275 nm. Results:The LOD ( limit of detection) of vanillin was 0. 45 μg·ml-1 . Excellent linearity was obtained within the concentration range of 1.990-99.500 μg·ml-1(r=1.000 0). The average recovery of vanillin in different dairy products with low, medium and high levels varied between 96. 26% and 100. 81% with RSD of 0. 15%-2. 22%. Con-clusion:The method is simple and reproducible, which can be applied in the rapid analysis of vanillin in dairy products.

Objective To investigate the dosimetric characteristics of hippocampal?avoidance prophylactic cranial irradiation ( HA?PCI ) in fixed?field intensity?modulated radiotherapy ( IMRT ) and volumetric modulated arc therapy ( VMAT) and the feasibility and risks of hippocampal avoidance. Methods Prophylactic cranial irradiation (PCI) was performed for 16 patients with localized small cell lung cancer ( SCLC) who were treated in our hospital from January to August, 2014, and achieved complete response ( CR) after chemoradiotherapy, with a prescribed dose of 25 Gy in 10 fractions. CT localization image was fused with brain MRI image to contour the hippocampus on the fused image, and the boundary of the hippocampus was extended 5 mm outward to form the area for reduced dose. IMRT and VMAT plans with hippocampal avoidance were developed separately, and the dose distribution in the whole brain, the hippocampus, and the 5?mm area outside the hippocampus was evaluated for these two plans. Independent?samples t test was applied to evaluate the difference between the two groups. Results The mean hippocampal volume in the 16 patients was 2. 76 cm3 ( range 2. 56 ?3. 01 cm3 ) . The mean radiation dose ( Dmean ) in the hippocampus during IMRT and VMAT was 9. 04± 0. 20 Gy and 10. 32± 0. 28 Gy, respectively, reduced by 66. 0% and 61. 2%, respectively, compared with the prescribed dose ( P=0. 55);Dmean in the area for reduced dose during IMRT and VMAT was 13. 57± 0. 90 Gy and 14. 86± 0. 60 Gy, respectively, reduced by 49. 0% and 44. 1%, respectively, compared with the prescribed dose (P=0. 88). Conclusions HA?PCI in IMRT and VMAT meets the clinical requirements, and can reduce the dose in the hippocampus while ensuring the whole?brain radiation dose, and therefore can be applied in PCI and provide a technical support to protect the patient’ s neurocognitive function.

Abstract: Objective　To screening new compounds that can inhibit the growth and biofilm formation of Staphylococcus aureus. Methods　Compounds that can inhibit the growth of Staphylococcus aureus were screened from the FDA approved drug library by 96 well plates. The absorbance value of 600 nm wavelength (OD600) was measured by Microplate Reader to detect the growth of Staphylococcus aureus planktonic cells in the culture supernatant. The minimum inhibitory concentration (MIC) of ozanimod against Staphylococcus aureus clinical isolates were detected by micro broth dilution method. The inhibitory effect of sub-inhibitory concentrations of ozanimod on the biofilm formation of Staphylococcus aureus was detected by crystal violet staining. Results　This study found that ozanimod could significantly inhibit the growth of Staphylococcus aureus SA113 (screening reference strain), and the MIC was 25.00 μmol/L. The MIC of ozanimod against 119 clinical isolates of Staphylococcus aureus [65 isolates of methicillin sensitive (MSSA) and 54 isolates of methicillin resistant (MRSA)] was 12.50 or 25.00 μmol/L. The MIC50 and MIC90 of ozanimod against the 119 Staphylococcus aureus isolates all were 25.00 μmol/L. This study found that 6.25, 12.50, 25.00 μmol/L of ozanimod could significantly inhibit the biofilm formation of 2 MSSA and 2 MRSA. The sub-MIC concentration of ozanimod (12.50 μmol/L) could significantly inhibit the biofilm formation of 14 MSSA and 11 MRSA, but had no inhibitory effect on the growth of planktonic cells of these Staphylococcus aureus isolates. Conclusion　Ozanimod can inhibit the growth of Staphylococcus aureus, including MRSA, and has good antibacterial activity. The sub-MIC concentration of ozanimod could significantly inhibit the biofilm formation of Staphylococcus aureus.
