Objective To observe the effect of stress caused by neuropathic pain on serum cortisol concentration and expres-sion of 11β-hydroxysteroid dehyarogenase 1(11βHSD1)and investigate the action mechanism of curcumin for alleviating neuropathic pain. Methods The 72 male SD rats were randomly divided into 4 groups with 18 rats in each group:sham operation group(Sham), chronic constrictive injury group(CCI),solvent contrast group(SC)and curcumin treated group(Cur100). Curcumin(100 mg/kg/d) was given after the operation in Cur100 group. Paw thermal withdrawal(PTWL)and paw mechanical withdrawal threshold(PMWT)of rats were measured on 2 pre-operative and 1,3,5,7,10,and 14 post-operative days. The animals were deeply anesthetized,the blood was taken from the heart,and the L4-L5 dorsal root ganglion(DRG)of the operated side was removed. The change of cortisol was measured by ELISA and the change of 11βHSD1 expression in spinal cord and DRG was determined by immunochemistry and Western blot. Results Compared with sham group,PTWL and PMWT decreased significantly after operation in CCI group(P<0.01),serum cortisol concentration was significantly increased(P<0.01)and the expression of 11βHSD1 was significantly increased in CCI group(P<0.01). Compared with CCI group,the PMWT and PTWL was increased in CCI group(P<0.05),the serum cortisol concentration was decreased(P<0.05)and the expression of 11βHSD1 was inhibited in Cur100 group(P<0.05). Conclusion Stress caused by neuropathic pain triggered the release of cortisol to the blood and increased the expression of 11βHSD1 at the same time. Cur-cumin could alleviate thermal hyperalgesia and mechanical hyperalgesia induced by CCI and could also inhibit the serum cortisol con-centration and the expression of 11βHSD1 in spinal cord and DRG,which was likely to be related to pathogenesy and maintenance of neuropathic pain.

Objective To assess the ability of the new software SonoAVC to measure follicular volume and to compare these volume calculations with those made by conventional methods. Methods Three-dimensional ultrasound imaging was used to acquire volumetric data from the ovaries of 50 women undergoing controlled ovarian stimulation as part of in-vitro fertilization treatment. SonoAVC was used to automatically measure the volume of follicles and virtual organ computer-aided analysis(VOCAL) was also applied to measure volume, which was used as the standard of volume measurement. And the three perpendicular diameters (xyz diameters) of follicles were manually measured by conventional two-dimensional(2D) ultrasound, which were used to estimate volume using the sphere formula. And the validity of each technique was compared using limits of agreement. Results One hundred and seventy-six follicles were studied. SonoAVC and VOCAL provided highly accurate and repeatable follicular volume measurements in all cases. Volumes estimated from manually derived follicular diameter measurements were less accurate and repeatable. VOCAL took more time in follicular volume of measurement than SonoAVC and conventional 2D displays. Conclusions SonoAVC provides highly accurate, repeatable,and efficient measurements of follicular volume.

The ras-mitogen activeted protein kinase pathway is responsible for regulation of many cel-lular processes, including differentiation, cytoskeletal organization, and protein trafficking. Much attention has been paid to them and their role in cancer therapy recently, and its inhibitor pathways are applied to clinical tes-ting, such as, Raf kinse inhibitors, MEK inhibitor, Src kinase inhibitor.

This paper is to study the inhibitory effect of water soluble polymers--methyl cellulose (MC), hydroxypropyl methyl cellulose (HPMC), hydroxypropyl cellulose (HPC-M), poloxamer (F68) and polyvidon (PVP) on osthole (OST) crystallization and investigate the impact of polymer concentration and viscosity on crystallization behavior. Also, UV spectrophotometry method was used to determine the drug concentration at different time point to draw the OST concentration-time curve. Results show that HPMC has the most significant inhibition effect on OST crystallization, and drug concentration level is 1.61 times higher than that in control solution within 8 h followed by PVP (1.54) and MC (1.45) respectively. The kinetics of OST recrystallization can be described using first-order reaction, and the crystallization rate constants obtained by analyzing the regression equation indicate that HPMC-60SH-4000 and HPMC-60SH-10000 can greatly influence OST crystal formation. The dissolution rate of drugs precipitated from water-soluble polymer solutions is faster compared with controls in pH 1.2 HCl and pH 6.8 phosphate buffers, which demonstrated that water-soluble polymers can not only change the behavior of drug crystallization but markedly improve the dissolution rate of water insoluble drugs.
