OBJECTIVE:
To explore the effect of septoplasty on the modality of inferior turbinate in patients with a deviated nasal septum.
METHOD:
Twenty-three patients with nasal septum deviation underwent septoplasty without turbinate surgery. All patients underwent CT imaging scans before and 3 months after the surgery. The thicknesses of the medial mucosa, lateral mucosa,and the cross-sectional areas of the inferior turbinate were measured and compared using the Wilcoxon signed rank test. P<0. 05 was considered statistically significant.
RESULT:
On the concave side of the septum, the thickness of the medial mucosa of the inferior turbinate was(5. 3+/-1.5) mm to (4. 1+/-1. 2) mm (P<0. 05), the thicknesses of the lateral mucosa of the inferior turbinate was(2. 5+/-0. 9) mm to (2.0+/-0. 9) mm (P>0. 05), and the cross-sectional area of the inferior turbinate was(139. 8 +/- 35.6) mm2 to( 110. 3 +/- 22.6)mm2 (P<0.05), pre- and post-operatively. On the convex side of the septum , the thickness of the medial mucosa of the inferior turbinate was(1.0 +/- 0. 6) mm to(4. 3 +/- 0. 6) mm (P>0. 05), the thicknesses of the lateral mucosa of the inferior turbinate was(1. 9+/-1. 1) mm to (1. 9+/-1.3) mm (P>0. 05), and the cross-sectional area of the inferior turbinate was(104. 5+/-15. 8)mm2 to(108. 3 +/- 20. 8)mm2 (P>0. 05), pre- and post-operatively.
CONCLUSION
The compensatory hypertrophic inferior turbinate may be self-adaptability in modality soon after septoplasty, thus surgeons must take it into consideration before performing turbinate surgery.

【Objective】 To explore the role and mechanism of TRPC in promoting extracellular matrix (ECM) deposition in rat glomerular mesangial cells (HBZY-1). Methods Immunofluorescence staining was performed to observe the distribution and expression of TRPC1 and TRPC6 in HBZY-1 cells. After AngⅡ stimulation, qRT-PCR and Western blotting were used to detect the mRNA and protein expressions of Gαq/PLCβ4/TRPC signaling pathway main proteins and ECM deposition indicators (α-SMA, collagenⅢ and fibronectin). By silencing the expressions of TRPC1 and TRPC6 by RNA interference, the expressions of ECM deposition indicators were detected. Changes in [Ca2+]i influx were determined through Fluo-4AM Ca2+ imaging. 【Results】 Both TRPC1 and TRPC6 were expressed in HBZY-1, and were mainly located in cell membrane and cytoplasm. After AngⅡ stimulation, Gαq/PLCβ4/TRPC signaling pathway was activated, and the mRNA and protein expressions of Gαq, PLCβ4, TRPC1 and TRPC6 were all increased (P<0.05). [Ca2+]i influx also increased (P<0.01), and the mRNA and protein expressions of ECM deposition indicators (α-SMA, ColⅢ and Fn) were upregulated (P<0.05). Silencing the expressions of TRPC1 and TRPC6 by RNA interference led to decreased [Ca2+]i influx (P<0.05), and downregulated mRNA and protein expressions of ECM deposition indicators in HBZY-1 cells (P<0.05). The results suggested that inhibition of TRPC expressions could inhibit AngⅡ induced ECM deposition in HBZY-1 cells, which might be associated with decreased [Ca2+]i influx. 【Conclusion】 TRPC may be a novel therapeutic target of renal fibrosis.
