Objective To investigate the toxicity of alpha terthienyl to the larvae of Aedes albopictus , its influencing factors and effect on the larva deve lopment. Methods Under experimental ultraviolet A (UVA),the number of dead,pupal or eclosive mosquito larvae was determined on the condition of different doses of alpha terthienyl and different disposal time in the dark;the number of dead larvae was also determined under sunlight on the condition of different doses of alpha terthienyl and different disposal time to water. Results The LC 50 of alpha terthienyl to Aedes albopictus larvae was 2.37 ?g/L under UVA. The best effect was shown when the larvae were incubated with alpha terthienyl 3 h in dark. Alpha terthienyl could significantly inhibit the larva deve lopment and the emergence of the pupae. Under strong sunlight, the larvae were quickly killed by high concentration alpha terthienyl. The 24 hours effect of alpha terthienyl was better when it was applied at 5 AM than that of at 10 AM and 1PM. Conclusion Alpha terthienyl is an effective, practicable larvicide which prohibits the growth and development of the larvae of Aedes albopictus .

Objective: To compare the contents of saikosaponin a, d and total flavonoids in different parts of Hollow bupleurum to provide reference for the clinical use of medicinal parts.Methods: The determination was performed on a SHIMADZU Inertsil C18(250 mm×4.6 mm,5 μm)column.The mobile phase consisted of acetonitrile and water with the ratio of 40∶60, and the flow rate was 1.0 ml·min-1.The detection wavelength was 210nm, the column temperature was 40℃, and the injection volume was 10 μl.A colorimetric method was used to detect total flavonoids with the detection wavelength of 500 nm.Results: The calibration curve of Saikosaponin a, d and total flavonoids showed a good linear relationship respectively over the range of 0.21-1.26 mg·ml-1(r=0.999 6),0.25-1.51 mg·ml-1(r=0.9997) and 4.00-25.00 μg·ml-1(r=0.999 6).The average recovery was 99.27%(RSD=2.15%, n=6),99.4%(RSD=2.14%,n=6)and 99.03%(RSD=1.34%,n=6), respectively.The content of saikosaponin a and d respectively was 0.31% and 0.50% in the root, while that in the other parts was low.The content of total flavonoids was as high as 8.48% in flowers, and that in leaves, stem and root reduced in turn.Conclusion: The aerial parts of Hollow bupleurum are rich in flavonoids, and the content of saikosaponin in root is higher, therefore, the whole plant with root is more reasonable in the clinical use.

Objective Obstructive sleep apnea hypopnea syndrome (OSAHS) often causes damage to multiple systems, especially to the central nervous system, inducing cognitive dysfunction.This study aims to explore the possible correlation of the expressions of serum hypoxia-inducible factor-1α (HIF-1α) and brain-derived neurotrophic factor (BDNF) with cognitive impairment in rats under different hypoxia conditions.Methods Twenty-four Wistar rats were equally randomized into a normal control, a chronic intermittent hypoxia (CIH), and a chronic continuous hypoxia (CCH) group.The rats of the CIH group were placed in a hypoxia chamber filled with N2 and air, the oxygen concentration switched from (7±0.5)% to 21%, 1.5 minutes for each state and 4 minutes for each cycle, while those of the CCH group were placed in another hypoxia chamber with the oxygen concentration of (7±0.5)%, 8 hours a day and all for 30 days.Then we recorded the body weight of the rats, detected the expressions of serum HIF-1α and BDNF by ELISA, and observed the changes of behavior by Morris water maze test and those of the hippocampal morphological structure by HE staining.Results At 30 days after modeling, the body weight of the rats was significantly decreased in the CIH and CSH groups as compared with the normal control ([195.75±6.497] and [180.88±12.017] vs [218.63±15.287] g, P<0.05).Positioning navigation showed that the escape latency was significantly longer in the hypoxia models than in the controls (P<0.05), even longer in the CIH than in the CCH group (P<0.05).Spatial exploration test manifested a lower frequency of crossing the platform in the CIH and CCH groups than in the control ([2.63±1.45] and [3.22±1.30] vs [4.97±0.47] times, P<0.05).The expression levels of serum HIF-1α and BDNF were significantly higher in the CIH ([36.14±9.34] and [1625.34±332.44] pg/mL) and CCH ([27.27±6.88] and [1204.07±363.81] pg/mL) than in the normal control group ([14.11±4.06] and [1036.40±124.48] pg/mL) (P<0.05), even higher in the CIH than in the CCH group (P<0.05).HE staining exhibited scattered and disorderly arrangement of hippocampal neurons in the model rats, with unclear nuclear membrane, pyknosis of the nuclei, darkly stained cytoplasm, and some damaged cells.More obvious absence and vacuolization of some cells were observed in the rats of the CIH group.Conclusion Chronic hypoxia inhibits the growth and development of rats and induces cognitive dysfunction.High-level HIF-1α in chronic intermittent hypoxia indicates hypoxia-stress of the body, while compensatory increase of serum BDNF may be involved in neuronal cell damage regulation.
