OBJECTIVE:
To evaluate the relative factors influencing olfactory dysfunction in patients with chronic rhinosinusitis (CRS).
METHOD:
Visual analogue scale (VAS) was applied to measure the severity of olfactory dysfunction of 270 patients with CRS. Patients were divided into two groups, one was that the quality of life (QOL) of patients was affected by olfactory dysfunction (VAS > 5), the other was that without QOL affected by olfactory dysfunction (VAS ≤ 5). The association between age, gender, nasal polyps, allergic rhinitis, smoking history, early nasal surgery history and other clinical factors, and serum total IgE level, peripheral blood eosinophil count, peripheral blood mononuclear cell count and olfactory dysfunction was analyzed.
RESULT:
The number of patients with nasal polyps, allergic rhinitis, previous nasal surgeries, the level of serum total IgE, and the severity of edema were significantly increased in patients with impaired QOL associated with olfactory dysfunction (P < 0.05). Sex distribution, age, smoking history, deviation of nasal septum, eosinophil and mononuclear cell count did no statistically differ between the groups with and without impaired QOL associated with olfactory dysfunctions (P > 0.05). Serum total IgE increased (OR = 1.003, P < 0.01) and severe edema (OR = 2.483, P < 0.01) were the risk factors for the impairment of olfactory function, more notably for edema; whereas previous nasal surgeries was a protective factor (OR = 0.408, P < 0.01).
CONCLUSION
Sever edema and increased serum total IgE are risk factors, whereas previous nasal surgeries history is a protective factor for the olfactory dysfunction.

To clarify the active components in Guizhi Fuling capsule in treatment of intrinsic dysmenorrhea, pelvic inflammation and hysteromyoma, main components were gradually knocked out from the capsules, the effects of knockout capsules on uterine contraction, TNF-α secretion, murine splenocytes (SPL) and hysteromyoma cells proliferation were evaluated, respectively. The inhibition of capsules on uterine contraction was weakened by gradient knockout of paeoniflorin, paeonol, and amygdalin. The suppression of capsulte on TNF-α secretion was reduced by gradient knockout of gallic acid, cinnamaldehyde, pentagalloylglucose, and pachyman. The promotion of SPL cells proliferation was reversed by gradient knockout of gallic acid, paeoniflorin, cinnamaldehyde, quercetin, and pachyman. The depression of capsules on hysteromyoma cells proliferation was attenuated by gradient knockout of paeoniflorin, paeonol, pentagalloylglucose, and albiflorin. In conclusion, the compounds mentioned-above could be the key active basis of Guizhi Fuling capsule in treatment of intrinsic dysmenorrhea, pelvic inflammation and hysteromyoma.

Aim To investigate the effects of leptin on ?1(Ⅰ) collagen mRNA expression and protein production, and the roles of Janus kinase/signal transducers and activators transcription(JAK/STAT) signaling transduction pathway in increased ?1(Ⅰ) collagen mRNA expression stimulated by leptin in activated hepatic stellate cells(HSCs).Methods Firstly, ?1(Ⅰ) collagen mRNA expression and protein production as well as JAK1 and STAT3 phosphorylation induced by leptin at different doses in a human HSC cell line, LX-2 were determined by RT-PCR, ELISA, and Western-blot.Secondly, the effects of JAK1 inhibitor AG490 on JAK1 phosphorylation and ?1(Ⅰ) collagen mRNA expression stimulated by leptin were detected by Western blot and RT-PCR. Thirdly, the roles of AG490 and transfection with STAT3 antisense oligonucleotide(STAT3-ASON) in STAT3 phosphorylation after leptin were detected by Western blot. Finally, the effect of transfection with STAT3-ASON on ?1(Ⅰ) collagen mRNA expression after leptin was measured by RT-PCR.Results Leptin increased ?1(Ⅰ) collagen mRNA expression and protein production in a dose-dependent manner in LX-2, reaching a maximal level at 80 ?g?L-1 leptin. In addition, phosphorylation of JAK1 and STAT3 after leptin exhibited a time-dependent effect. Besides, JAK1 inhibitor AG490 completely blocked JAK1 and STAT3 phosphorylation and increased in ?1(Ⅰ) collagen gene expression after leptin in LX-2. Transfection with STAT3-ASON blocked STAT3 phosphorylation and increased ?1(Ⅰ) collagen mRNA by leptin in LX-2.Conclusion Leptin had a direct action on liver fibrogenesis by stimulating ?1(Ⅰ) collagen mRNA expression and protein production in activated HSC, and JAK/STAT signaling transduction pathway was involved in the process. JAK1 inhibitor AG490 and transfection with STAT3-ASON blocked the transduction pathway effectively in LX-2. Leptin may be an important factor in the development of hepatic fibrosis. Activated JAK1 and STAT3 signaling in human HSC line provided a novel molecular target for therapeutic intervention of liver fibrosis.

The aim of this study was to investigate the anti-inflammatory effect of Guizhi Fuling capsule and its active complex (consistent of 15 active compounds) on LPS-induced RAW264. 7 cells. The effect of Guizhi Fuling capsule and its active complex on cell viability in RAW264. 7 cells were determined by MTT assay. The inhibitory effect of Guizhi Fuling capsule and active complex on the releasing of IL-1β, TNF-α and PGE2 induced by LPS in RAW264. 7 cells was detected by ELISA assay. The expression of IL-1β and mPGES-1 in Guizhi Fuling capsule or active complex treated RAW264. 7 cells was examined by Western blot assay. Guizhi Fuling capsule and active complex showed no significant effect on the cell viability in RAW264. 7 cells at doses range from 12.5 to 400 mg x L(-1). Compared with LPS treated group, Guizhi Fuling capsule and active complex dose dependently reduced the releasing of IL-1β, TNF-α and PGE2 induced by LPS in RAW264. 7 cells. Moreover, the expression of IL-1β and mPGES-1 was decreased after Guizhi Fuling capsule and active complex treatment, which might contribute to the inhibitory effect of Guizhi Fuling capsule in the releasing of IL-1β, TNF-α and PGE2. This study provided the evidence that Guizhi Fuling capsule and active complex remarkably inhibited the releasing of IL-1β, TNF-α and PGE2induced by LPS in RAW264. 7 cells by reducing the expression IL-1β and mPGES-1. This study provided an experimental basis of Guizhi Fuling capsule for the treatment of inflammation and a theoretical basis for the development of effective compounds of Guizhi Fuling capsule.
