Objective To investigate the correlation between epicardial fat thickness (EAT) and the risk factors of coronary artery disease (CAD) as well as the severity of coronary lesions with echocardiography,Methods According to the results of coronary angiography,80 patients underwent coronary angiography were divided into coronary heart disease group (CHD group,4 6 cases) and without coronary heart disease group (control group,34cases),and according to coronary artorrythe severity,CHD goup was divided into subgroups of single-vessel disease (24 cases) and multivessel disease subgroup(22 cases).Tho epioardial fat thickness on the free wall of the right ventricle was measured at end-systole from the para-sterna,long-axis vlews.The relationship between EAT and the risk factors of CAD (such as age,gender,hypercholesterolemia,hypertenston,diabetes,smoking,family CAD history) as well as the severity of coronary lesions were analyzed.Results EAT in multivessel disease CAD group [(8.85 ± 1.44)mm] was significantly higher than that in single vessel CAD group[(6.86 ± 1.09) mm] and control group [(4.58 ± 1.12) mm] (all P ＜ 0.01).EAT was significantly related with the risk factors of CAD.Although the risk factors of CAD such as age,blood glucose,blood pressure were adjusted,EAT was still independently associated with CAD (OR:5.394,95 ％ CI:1.700 ～ 17.1 12,P =0.004).Concluslon The level of EAT is significantly correlated with CAD and the severity of coronary lesions.

The model of vaginal candidiasis in Kunming mice was constructed in order to search for the optima construction conditions and provide an economic animal model of Candida albicans (C. albicans) vaginitis. Estrogen benzoate (E2) was given to mice at different concentrations ranging from 0.0 to 0.05 mg/mouse (4 levels) beginning 72 h prior to vaginal inoculation, then mice were inoculated intravaginally with various concentrations of stationary-phase C. albicans blastoconidia (ATCC90028) (5 levels) in 20 microL of phosphate-buffered saline (PBS) in each E2 level. General state, scores of genital pathology, the hyphae and vaginal fungal burden (CFU) in vaginal lavage fluid, the hydrops rate of uterus and vaginal tissues for pathological section in mice were observed and obtained at day 2, 4, 7, 14 and 21 after inoculation. The results showed the infection rate in mice was related to the dosage of E2 and concentration of C. albicans blastoconidia. Additionally there was better cross-effect between the two treated factors. The infection rate was about 80% on the day 4, and could reach 100% on the day 7 until the end of experiment after inoculated intravaginally in groups of E2I3, E2 0.025 mg/mouse injected hypodermically and inoculated intravaginally with 5 x 10(4) C. albicans blastoconidia, and large amount of hyphae and blastoconidia could be observe in superficial layer tissue and canal of vaginal by PAS. From the results in our experiment it was concluded that E2I3 was the optima construction condition in kunming mice.

To investigate the effects of the free radical, 1,1-Diphenyl-2-picylhydrazyl, on cochlear blood flow, 20 guinea pigs were divided into 3 groups at random, 6 for control group, 6 for 1 mmol/L group and 8 for 0.1 mmol/L group. 2 microliters vehicle or drugs were dropped into round window membrane (RWM). Cochlear microcirculation was monitored by laser Doppler flowmeter (LDF), and mean arterial blood flow (MABP), which was transferred by pressure conductor sensor and preamplifier, was simultaneously recorded on the computer. Our results showed that MABP was stable throughout the experiment. Cochlear blood flow (CBF) increased by 10.32% (P < 0.05) in 1 mmol/L group, and decreased by 4.89% in 0.1 mmol/L group (P < 0.05). In control group cochlear microcirculation showed no significant changes. It is concluded that DPPH exerted effects on cochlear microcirculation.

Catch-up growth,a phenomenon that occurs after a short time growth-inhibiting condition,has been proved to be strongly associated with insulin resistance.But the mechanism of insulin resistance in the process of catch-up growth is not clear.

Noninvasive continuous positive airway pressure (CPAP) for the ventilation treatment of obstructive sleep apnea-hypopnea syndrome (OSAHS) is the first-line treatment method. This article aims to describe the effect of surgical operation especially for the UPPP in the individualized comprehensive treatment of OSAHS and the importance of surgical technique. Lower compliance is the bottleneck of CPAP therapy in clinical application, for the OSAHS patients with treatment failure in CPAP or those cannot accept CPAP therapy, when with no other ideal instrument therapeutics, accurate diagnosis of position in airway obstruction with an adequate surgical operation is the treatment,of choice. Surgical operation is particularly important either as a fore-lying means to improve the CPAP treatment compliance or as an independence treatment method of OSAHS. The pharyngeal cavity is the most common obstructive plane in patients with OSAHS. The operation of traditional UPPP aiming at the expansion of pharyngeal cavity is the classics surgery to solve obstruction in this plane, the lower operation effective rate is the main reason of restriction in its development. How to improve the effective rate of surgical treatment of OSAHS is our surgical goal. The effective rate of surgical operation treatment in OSAHS rely on the following sides: to follow the OSAHS individualized comprehensive treatment principle, reasonable choice of surgical operation indication, the precise localization diagnosis of upper airway obstruction, adequate surgical operation and skilled surgical techniques.
