Objective:To analyze the inhibitory effect of genistein on matrix metalloproteinase-2 (MMP-2) and matrix metalloproteinase-9 (MMP-9) through inhibition of nuclear factor-kappa B (NF-κB ) ***: A total of 36 female mice were divided into six groups (n=6 in each group): control group (untreated mice), endometriosis mice group, and endometriosis mice groups administered with genistein at different doses (1.30 mg/day;1.95 mg/day;2.60 mg/day;and 3.25 mg/day). The genistein treatment was performed for 14 d. The expressions of NF-κB , MMP-2 and MMP-9 on the endometriosis lesions were analyzed by the immunohistochemical ***: The activity of NF-κB in the endometriosis group increased significantly than that of the control group (P0.05). The four doses of genistein administration were capable of significantly reducing the expression of MMP-2 compared to that of the endometriosis group (P0.05). Administration of genistein at different doses was capable of significantly reducing the expression of MMP-9 compared to that of the endometriosis group (P0.05). Conclusions:Genistein suppresses the expression of MMP-2 and MMP-9 through suppressing NF-κB activity in the peritoneum of murine model of endometriosis.

The existing estimates of the volume transport from the Pacific Ocean to the South China Sea are summarized, showing an annual mean westward transport, with the Taiwan Strait outflow subtracted, of 3.5±2.0 Sv （1 Sv=-0^6 ma s^-1）. Results of a global ocean circulation model show an annual mean transport of 3.9 Sv from the Pacific to the Indian Ocean through the South China Sea. The boreal winter transport is larger and exhibits a South China Sea branch of the Pacific-to-Indian Ocean throughflow, which originates from the western Philippine Sea toward the Indonesian Seas through the South China Sea, as well as through the Karimata and Mindoro Straits. The southwestward current near the continental slope of the northern South China Sea is shown to be a combination of this branch and the interior circulation gyre. This winter branch can be confirmed by trajectories of satellite-tracked drifters, which clearly show a flow from the Luzon Strait to the Karimata Strait in winter. In summer, the flow in the Karimata Strait is reversed. Numerical model results indicate that the Pacific water can enter the South China Sea and exit toward the Sulu Sea, but no observational evidence is available. The roles of the throughiiow branch in the circulation, water properties and air-sea exchange of the South China Sea, and in enhancing and regulating the volume transport and reducing the heat transport of the Indonesian Throughflow, are discussed.

In order to quantitatively estimate the volume and property transports between the South China Sea and Indonesian Seas via the Karimata Strait, two trawi-resistant bottom mounts, with ADCPs embedded, were deployed in the strait to measure the velocity profile as part of the South China Sea-Indonesian Seas trans- port/exchange （SITE） program. A pair of surface and bottom acoustic modems was employed to transfer the measured velocity without recovering the mooring. The advantage and problems of the instruments in this field work are reported and discussed. The field observations confirm the existence of the South Chi- na Sea branch of Indonesian throughflow via the Karimata Strait with a stronger southward flow in boreal winter and weaker southward bottom flow in boreal summer, beneath the upper layer northward （reversal） flow. The estimate of the averaged volume, heat and freshwater transports from December 2007 to March 2008 （winter） is （-2.7±1.1）×10^6 m^3/s, （-0.30±0.11） PW, 2008 （summer） is （1.2±0.6）×10^6 m^3/s, （0.14±0.03） PW, （-0.18±0.07） × 106 m3/s and from May to September （0.12±0.04）×10^6 m^3/s and for the entire record from December 2007 to October 2008 is （-0.5±1.9）×10^6 m^3/s, （-0.05±0.22） PW, （-0.01±0.15）×10^6 m^3/s （nega- tive/positive represents southward/northward transport）, respectively. The existence of southward bottom flow in boreal summer implies that the downward sea surface slope from north to south as found by Fang et al. （2010） for winter is a year-round phenomenon.

Electrochemical capacitor （EC） is a promising energy storage device which can be hybridized with other energy conversion or energy storage devices. One type of ECs is pseudocapacitor made of metal oxides. WO3 is an inexpensive semiconductor metal oxide which has many applications. However the application of WO3 as an EC material was rarely reported. Therefore in this research EC was prepared from WO3 nanomaterial synthesized by a sol-gel process. The WO3 gel was spin-coated on graphite substrates and calcined at various temperatures of 300~C, 400℃, 500℃ and 600℃ for 1 h. Cyclic voltammetry （CV） measurements were used to observe the capacitive property of the WO3 samples. SEM, XRD, FTIR and Brunauer-Emmett-Teller （BET） analyses were used to characterize the material structures. WO3 calcined at 400~C was proved to have the highest capacitance of 233.63 Fo g^-1 （1869 mFo cm-2） at a scan rate of 2 mVo s-1 in 1 mol/L H2SO4 between potentials -0.4 and 0.4 V vs. SCE. Moreover it also showed the most symmetric CV curves as the indication of a good EC. Hence WO3 calcined at 400℃ is a potential candidate for EC material of pseudocapacitor type.
