Objective To study the expression of transforming growth factor ?(TGF-?) and connective tissue growth factor(CTGF) in renal interslitium of patients with lupus nephritis(LN) and itssignificance. Methods Expression of TGF-?1, CTGF, CD3, CD68, proliferative nuclear cell antigen(PCNA) and ?-smooth muscle actin (?-SMA) in renal interstitium of LN patients were detected byimmunohistochemical staining. The degrees of staining in LN patients were compared to those in patients withminimal change disease (MCD) . Results Expression of TGF-?1 and CTGF in renal interstitium elevatedsignificantly in LN patients as compared to those in MCD patients. There was a positive correlation betweenthe expression of TGF-?1 and CTGF ( r = 0. 5316, P = 0. 023). The expression of ?-SMA and the numbersof CD3, CD68 and PCNA positive cells in renal intersitium were significantly increased in LN patients as compared with MCD cases. The expression of a-SMA in renal interstitium was correlated with the degree of renal interstitial lesions or fibrosis( r = 0. 436, P = 0.032) . Conclusion The increased expression ofTGF-?1 and CTGF in LN patients may be involved in the damage of renal interstitium and the infiltration ofinflammatory cells.

Objective To explore the efficiency of endoscopic septoplasty with submucous resection for the treatment of 220 patients with deviated nasal septum and report our experience in this field. Methods From May 2006 to May 2010, 220 patients with deviated nasal septum were treated by endoscopic septoplasty with submucous resection to decompress the stress points, resect the deviated parts and implant the reshaped bone of nasal septum, while retaining the normal structure of nasal septum with minimally invasive technique. Results Satisfactory effects were achieved in all the 220 patients, showing centered septal structure and disappeared symptoms such as nasal obstruction, headache and nasal hemorrhage, but no complications including perforation of nasal septum, depressed nasal bridge and septal chalasia and flaring. Conclusion Rhino-endoscopic septoplasty with submucous resection can substantially retain the original structure of nasal septum and thus is proven to be a desirable operation with multiple advantages including minimal invasiveness, quicker healing and fewer complications.

Abstract? AIM: To investigate changes of anterior chamber parameters after posterior chamber phakic implantable collamer lens ( ICL ) surgery and its correlation with intraocular pressure ( IOP) .?METHODS: This was a retrospective case series study. Seventy four eyes in 43 myopia patients were examined by Allegro Oculyzer anterior segment tomography to obtain the changes of anterior chamber volume ( ACV ) , anterior chamber angle ( ACA) , central anterior chamber depth ( ACD) and vault, meanwhile, to measure the IOP to analyze the correlation with anterior chamber parameters.?RESULTS: Compared with preoperative, ACV, ACA, ACD all decreased apparently ( P <0.01 ) in the postoperative period of 1, 3, and 6mo.ACV, ACA and ACD showed their stability in each period after the surgery.There were changes of vault in 1 and 6mo ( t=27.66, P=0.01).IOP had not altered when compared with the preoperative.This research revealed that IOP had no relation with ACV, ACA, ACD and vault in every phase( all P>0.05).?CONCLUSION:For patients underwent ICL, the anterior chamber parameters all decreased which included ACV, ACA, ACD, and had stabilized since early postoperative period. Correspondingly, IOP was stable and had not correlate with ACV, ACA, ACD and vault, however the long-term observation is still necessary.
