Objective To investigate the mechanism of insulin resistance (IR) with coronary heart disease (CHD) by the relationship study between IR and the risk factors of CHD as well as the severity of coronary lesions. Methods One hundred and twenty three patients with at least one vessel ≥50% luminal narrowing were analyzed from our consecutive angiographic data base, excluding patients concomitant with hepatic, renal, pancreatic diseases, thyroid disorders and diabetes mellitus (DM) with insulin therapy. Oral glucose tolerance test (OGTT), blood lipid, plasma insulin were performed in all patients. Insulin resistance was assessed by homeostasis model assessment (HOMA) to investigate the relationship study between insulin resistance and the risk factors of CHD,severity of coronary lesions as well as the clustering of risk factors (hypertension, overweight, impaired glucose tolerance/DM, high serum triglycerides, low high density lipoprotein cholesterol). Results The level of IR was correlated with the levels of body mass index (BMI), fasting glucose, postprandial glucose, fasting insulin, postprandial insulin, hypertension, serum triglycerides, and high density lipoprotein cholesterol. Meanwhile the level of IR was associated with clustering of risk factors and the extent and the severity of coronary lesions. Conclusion Insulin resistance may be the basis for disease. In the primary and secondary prevention of CHD, we should not only treat syndromes but also reduce the level of IR.

Objective To investigate the effect of three kinds of skin external use in the prevention and treatment of radiation dermatitis in patients with nasopharyngeal carcinoma. Methods 120 patients with nasopharyngeal carcinoma who were treated form August 2014 to October 2015 were divided into three groups by random number table method, namely, aloe vera gel group, triethanolamine cream group, radiation treatment of skin protectants (lifuning) group. Except for different medications among the groups, the other conditions remained relatively consistent. 3 groups were compared in the radiotherapy classification, area, local pain score, and topical drug costs during the radiotherapy and the radiation dose when radiation dermatitis occurred the first time. Results Three kinds of skin external use had a preventive effect, but the effect was different. Three groups′ patients with radiation dermatitis incidence was 100%, but occurred at different levels. Aloe vera gel cream group and triethanolamine group were mainly for gradeⅡradiation dermatitis, grade IV radiation dermatitis occurred in 2 cases and 4 cases, lifuning group were mainly for grade Ⅰ and grade Ⅱ radiation dermatitis, grade Ⅲ radiation dermatitis only occurred 2 cases, noⅣgrade radiation dermatitis occurred. Comparison among the three groups, the difference was statistically significant (H=8.758,P<0.05). 3 groups of patients after treatment all suffered pain, 12 patients in triethanolamine cream group , 7 patients in lifuning group , only 2 cases in aloe vera gel group (H=8.586,P<0.05). The average cost of skin external used in 3 groups was different, triethanolamine cream group was 546.0 yuan, lifuning group was 458.2 yuan, and aloe vera gel group was 157.5 yuan. Among the three groups pairwise comparison, the differences in triethanolamine cream group and aloe vera gel group were statistically significant in pain (χ2=9.62,P<0.05), aloe vera gel group was better than the group of triethanolamine cream, the differences among radiation dermatitis grade, size and radiation dose of radiation dermatitis occurred the first time were not statistically significant (P>0.05). The difference between in lifuning group and triethanolamine cream group in pain had no statistically significant (χ2=2.47,P>0.05), other indexes had significant differences (P < 0.05). Lifuning was better than the triethanolamine cream to reduce and delay the onset and deterioration of radiation dermatitis and could prevent a widening of the area of radiation dermatitis;aloe vera gel group and lifuning group had a significant difference in radioepidermitis grade (χ2=6.32,P<0.05). Lifuning was better than the aloe vera gel and was more conducive to reduce and delay the occurrence of radiation dermatitis, other indexes differences had no statistically significant (P>0.05). Conclusions Considering the efficacy, pain and price three aspects which skin external use prevention and treatment radiation dermatitis patients with nasopharyngeal carcinoma, lifuning as the mixture of triethanolamine and aloe can effectively reduce and delay the chance of radiation dermatitis, reduce the radiation field experience of local pain, and affordable, the patients are more acceptable, it′s worthy of clinical use.

2', 3', 5'-Tri-O-acetyl-N6-(3-hydroxylaniline)adenosine (WS070117) is a derivative compound of natural product cordycepin. It has significant lipids regulating activity and low toxicity which has been proved by in vitro and in vivo experiments. In this study, 1H NMR-based metabolomics was used to investigate the dose-related effects of WS070117 on hyperlipidemia of high-fat-fed hamsters. The hyperlipidemic hamsters were administrated with six different doses of WS070117, including 3, 12, 50, 100, 200 and 400 mg x kg(-1) x d(-1). 1H NMR spectra of hamster serum were visually and statistically analyzed using two multivariate analyses: principal component analysis (PCA) and orthogonal partial least squares-discriminant analysis (OPLS-DA). As a result, WS070117-treated groups showed dose-related regulation of metabolites associated with lipid metabolism, choline metabolism and glucose metabolism. The dose of 3 mg x kg(-1) x d(-1) of WS070117 only exhibited a little lipids regulating activity. However, the doses of 12 and 50 mg x kg(-1) x d(-1) of WS070117 both regulated the contents of metabolites to reverse significantly toward normal levels. When the dose of WS070117 reached 100 mg x kg(-1) x d(-1), it was more effective than positive control drugs. The work suggested that NMR-based metabolomics might be a valuable approach to evaluate dose-related effects of lipids regulating compounds.
