Journal of International Pharmaceutical Research 2017;44(6):551-555,560
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 provide basic industrial research and development recommendations for the supply-side structural reform in drug distribution in China. METHODS:Structure-conduct-performance(SCP)analysis paradigm from Harvard was used for in-depth study of market structure,business conduct and business performance in China since 2010. RESULTS:Since 2010, drug distribution industry in China had shown the scale of decline in the growth rate,low market concentration,increased barriers to entry,the leading of state-owned capital,etc. Though corporate mergers and acquisitions and public financing expanded the scale,management information,third-party logistics,Internet+and pharmacy alliance business model flourished,the industry op-erating performance was poor,state-owned enterprises showed poor performance. CONCLUSIONS:The transformation and upgrad-ing of the industry business model should be promoted by targetedly accelerating the supply-side structural reforms in the drug distri-bution industry,encouraging corporate finance mergers,breaking local protectionism,developing cooperative pharmacies and phar-maceutical third-party logistics alliances and leveraging the Internet.

Objective To explore the effects of Tianqijiangtang capsule combined with Metformin on the levels of IL‐6 ,TNF‐α and C‐RP protein in patients with T2DM. Methods 80 T2DM were randomized into control group (treatment with Metformin ,n= 40) and treatment group (treatment with Tianqijiangtang in combination with Metformin ,n=40). The changes of levels of IL‐6 ,TNF‐α and C‐RP were observed before and after the treatment. Results Compared to the pretreatment in the same group and after treatment in control group ,IL‐6 ,TNF‐αand C‐RP of treatment group were reduced significantly [(6.79 ± 0.60) ,(7.15 ± 0.62) vs (5.08 ± 0.43)pg/ml;(8.94 ± 0.55) ,(8.61 ± 0.66) vs (5.18 ± 0.45) pg/ml;(6.79 ± 0.60) ,(6.58 ± 0.59) vs (5.56 ± 0.30) mg/L ,P<0.01]. Conclusion Tianqijiangtang capsule combined with Metformin can decrease the levels of IL‐6 ,TNF‐αand C‐RP in T2DM patients.

The Renca-bearing mice were treated by combined fibroblast-mediated IL-2 and G-CSF gene therapy. The survival periods of Renca-bearing mice were prolonged markedly and 75% of Renca-bearing mice were cured. The spleens of Renca-bearing mice treated by fibroblast-mediated G-CSF gene therapy were larger than the spleens of other mice. Histologic analysis of tumor showed that there were a number of infiltrating eosinophils. The NK, LAK and CTL activity induced from the splenocytes of the tumor-bearing mice increased siginificantly when the mice were treated by fibroblast-mediated IL-2 gene therapy and the cytotoxicity of macrophages also increased. The results demonstrated that the and - tumor responses might be induced more significantly by combined fibroblast-mediated IL-2 and G-CSF gene therapy and better antitumor effect may be achieved.
