Objective To investigate the clinical efficacy of open radical mastoidectomy (ORM) combined with ear cavity angioplasty and mastoid cavity obliteration in treatment of cholesteatoma otitis media (COM). Methods Eighty-two patients with COM were divided into 2 groups according to surgical approach: control group (41 patients undergoing simple ORM) and observation group (41 patients undergoing ORM combined with ear cavity angioplasty and mastoid cavity obliteration). The clinical efficacy and recurrence rate between the 2 groups were compared. Results The total effective rate, dry ear rate and eardrum healing survival rate in observation group were significantly higher than those in control group: 95.12% (39/41) vs. 78.05% (32/41), 97.56% (40/41) vs. 75.61% (31/41) and 90.24%(37/41) vs. 73.17% (30/41), and there were statistical differences (P<0.01). The dry ear time and epithelialization time in observation group were significantly shorter than those in control group:(31.23 ±5.69) d vs. (48.12 ± 8.97) d and (24.41±3.23) d vs. (36.24 ± 5.69) d, the postoperative pure tone audiometry (PTA) and air bone gap (ABG) in observation group were significantly lower than those in control group:(25.61 ± 5.67) dB vs. (35.41 ± 8.23) dB and (13.24 ± 3.98) dB vs. (19.02 ± 5.52) dB, and there were statistical differences (P<0.01). There was no statistical difference in the incidence of complications between 2 groups (P>0.05). The recurrence rate in observation group was significantly lower than that in control group:2.44%(1/41) vs. 14.63%(6/41), and there was statistical difference (P<0.05). Conclusions The application of ORM combined with ear cavity angioplasty and mastoid cavity obliteration in the treatment of COM has significant effect, with rapid postoperative dry ear and epithelialization, fewer complications and lower recurrence rate. It should be widely applied.

Objective To evaluate the effect of telmisartan on serum adiponectin and urine microalbumin(mAlb) level by administrating it to mice with simple obesity, so as to explore new therapies for obesity-related kidney diseases.Method A total of 24 8-week-old male OB mice and 8 8-week-old male C57 mice were selected for this study.The genetic background of OB mouse was C57 mouse, but the lepin gene was deleted in OB mouse.OB mice were randomly divided into 3 groups by body weight and fed with high-fat diet for 12 weeks: model group (M group), telmisartan group (T1 group) and losartan group (T2 group).C57 mice acted as control and were fed with general diet for 12 weeks.Serum adiponectin and blood glucose levels were measured before and after treatment.24 h urine was collected to measure urine mAlb.Quantitative real-time PCR (qRT-PCR) was used to measure the expression level of peroxisome proliferators-activated receptors gamma mRNA(PPARγ mRNA).HE stain was used to observe the morphological changes of kidney and measure the glomerular diameter.Body weight, serum adiponectin level, blood glucose level, urine mAlb level, expression level of kidney PPARγ mRNA, kidney wet weight and glomerular diameter of 4 groups were compared and a correlation analysis was carried out by Person correlation coefficient.Results Compared with C group, the urine mAlb level in M group increased (P＜0.01), serum adiponectin level and the expression level of kidney PPARγ mRNA in M group decreased (P ＜ 0.01);The urine mAlb level was negatively correlated with serum adiponectin level and expression of kidney PPARγmRNA (r=-0.773,P ＜ 0.01;r=-0.469, P ＜ 0.01).The urine mAlb level in T1 group was lower than M group (P ＜ 0.05),serum adiponectin level and expression of kidney PPARγmRNA in T1 group were higher than M group (P ＜ 0.05).Compared with T2 group, the urine mAlb level in T1 group decreased, serum adiponectin level and expression of kidney PPARγ mRNA in T1 group increased (P ＜ 0.05);Compared with M group, the urine mAlb level in T2 group decreased (P=0.01).The morphological changes of kidney:glomerular volume increase and focal segmental sclerosis were found in some mice in M group and T2 group.No glomerular volume increase and focal segmental sclerosis were observed in T1 group.Conclusions Telmisartan can reduce urine microalbumin, whose mechanism might be that telmisartan can active the PPARγand promote the level of serum adiponectin.
