Objective To investigate the characteristics of serum oxidized low density lipoprotein (ox-LDL) and traditional cardiovascular risk factors of premature coronary artery disease (PCAD). Methods Sixty-six patients with coro-nary atrery disease (CAD) confirmed by angiography were selected to be PCAD group, and 56 patients with normal coronary artery confirmed by angiography were included in control group. The serum levels of ox-LDL, high density lipoprotein choles-terol (HDL-C), triglyceride (TG), creatinine (SCr), uric acid (UA), other serum biochemical indicators and differences of the proportions of male, hypertension, diabetes, smoking history and family history of CAD were compared between two groups. Results (1)There were higher serum values of ox-LDL, TG, SCr, UA, fasting blood glucose (FBG) and proportion of male pa-tients in PCAD group than those of control group (P<0.05), but there was a lower plasma level of HDL-C in PCAD group than that of control group (P<0.05). There were significant differences in other indicators between two groups. (2) There were positive correlations between UA, SCr and ox-LDL ( rs were 0.243 and 0.186 respectively, P were 0.006 and 0.034 respective-ly). (3)The logistic regression analysis showed that ox-LDL, HDL-C and SCr were influential factors to PCAD(OR were 1.155, 0.143 and 1.052 respectively). Conclusion Elevations of ox-LDL, HDL-C and SCr are independent predictors of PCAD.

OBJECTIVE To study the clinical usability of virtual endoscopy(VE) in tympanoplasty.METHODS A total of 102 patients (204 ears) were observed by virtual endoscopy. Tympanoplasty was performed in 72 cases (75 ears) including 53 cases (55 ears) with chronic otitis media and 19 cases (20 ears) with congenital microtia and middle ear dysmorphia. Ossicular chain reconstruction was conducteded in 65 ears at the same time. RESULTS The ossicular chain was showed eroded in 19 ears of 23 patients with cholesteatoma otitis media pre-operatively by VE, but was found eroded in all of 23 ears during operation. The ossicular chain was showed eroded in 29 ears of 32 patients with osteitis otitis media pre-operatively by VE, but during operation it was found 23 ears with malleus and incus eroded, 11 ears without head of stapes or up-structure of stapes. VE showed 18 ears with congenital microtia and middle ear malformation and 2 ears with small tympanic cavity and no ossicular chain preoperatively, and operation proved 17 ears with severe ossicular malformation, 2 ears without stapes, 1 ear with vestibular window atresia. There were 2 ears with sudden hearing loss after tympanoplasty, the VE showed ossicular displacement. The coincidence rates between VE and operation view were 92 % in patients with otitis media and 100 % in patients with congenital microtia and middle ear malformation. CONCLUSION VE can supply reliability data for evaluation of the damaged ossicular chain and efficacy of tympanoplasty.

Objective To determine the association of acanthosis nigricans(AN) with values for estimating insulin resistance and adipocytokine levels in simple obese children. Methods These subjects concluded 38 simple obese children. AN was present in 17 of 38 children. Height, weight and abdominal circumference were recorded and fasting blood sample was obtained for measurement of blood glucose, plasma insulin, leptin, and plasminogen activator inhibitor 1 (PAI-1) levels which were known as the risk factors of cardiovascular disease. We obtained homeostasis model assessment insulin resistance index (HOMA-R) by fasting blood glucose and plasma insulin levels. Results The severity of obesity, abdominal circumference, fasting insulin levels and HOMA-R were significantly higher in obese children to AN compared to those without AN. There was the tendency that children with AN had higher levels of leptin and PAI-1 compared to children without AN. Conclusions These results suggest that obese children with AN may have a risk of cardiovascular disease as well as type 2 diabetes mellitus.
