Objective To investigate the clinical efficacy of losartan combined with atorvastatin in the treatment of essential hypertension and its influence on the plasma high sensitive C reactive protein(hs-CRP),endothelin (ET) and the level of nitric oxide(NO).Methods According to the digital table,84 patients with primary hypertension were randomly divided into the two groups of 42 cases,the control group was given losartan for treatment,the observation group was treated with losartan combined with atorvastatin.The clinical curative effect and the changes of plasma hs-CRP,ET and the level of NO before and after treatment were compared between the two groups.Results The effective rate of the observation group was 92.86％,which was significantly higher than 80.95％ of the control group(x2 =7.85,P ＜ 0.05);The levels of plasma hs-CRP and ET of the observation group after treatment were (3.02 ± 0.29) mg/L and (34.44 ± 4.59) μg/L,which were significantly lower than (5.30 ± 0.38) mg/L and (58.30 ± 5.27) μg/L of pretreatment and (4.95 ± 0.36) mg/L and (55.93 ± 5.71) μg/L of the control group (t =7.43,8.10,7.89,8.56,all P ＜ 0.05);The NO level of the observation group after treatment was (70.47 ± 4.58)μmol/L,which were significantly higher than (44.43 ± 3.41)μ mol/L of pretreatment and (46.33 ± 3.81) μmol/L of the control group(t =8.69,9.04,all P＜0.05).Conclusion Atorvastatin combined with losartan has a definite effect in treatment of primary hypertension,which can significantly improve the inflammation and endothelial function of patients that has a good clinical application value.

This article is to report our observation of the therapeutic effect of antihista-mine and anti-inflammation drugs on the early pulmonary edema in respiratory burns. Thirty-two dogs were employed in the experiment and divided into 4 groups: Group Ⅰconsisted of 8 dogs which were inflicted with respiratory tract burns without any treatment and served as the control.Group Ⅱ: 8 animals received H1H2 receptor antagonists of benadryl and cime-tidine after the burns.Group Ⅲ: 8 animals were treated with indomethacin after the burns.Group Ⅳ: 8 animals were treated with dexamethasome after the burns.It was found that under conventional light microscope the interstitial pulmonary edema in GroupⅡ was the mildest and the alveolar edema in both Groups Ⅱ and Ⅲ was milder than in the other two. The difference between Groups Ⅰ and Ⅱ was statistically significant(P

In order to investigate the impact of fulvic acid (FA) on the hydroxylysyl glycosylation in collagen bio-synthesis, 40 NMRI mice were divided into two groups (n = 20 in each group, consisting 10 females and 10 males). The animal was maintained for two generations by different diets: control group with normal water and food and study group with water containing 30 mg/L FA and normal food. The second generation of the animal was slaughtered, and the biochemical parameters of collagen content and the degree of collagen hydroxylysyl glycosylation in skin, rib and tibia were detected by biochemical methods. The mean value of collagen in the study group was increased slightly, and no significant difference between study group and control group was found (P > 0.05), but the content of glucose-glactose-hydroxylysine (GGH) was significantly decreased in the study group in comparison with the control group (P<0.01). It was suggested that through the decrease of GGH 30 mg/L FA could inhibit the activity of galactosyl-hydroxylysylglucosyl-transferase and further disturb the post-translational modification of collagen intracellularly.

Corneal opacity is one of the most commonly used parameters for estimating postmortem interval (PMI). This paper proposes a new method to study the relationship between changes of corneal opacity and PMI by processing and analyzing cornea images. Corneal regions were extracted from images of rabbits' eyes and described by color-based and texture-based features, which could represent the changes of cornea at different PMI. A KNN classifier was used to reveal the association of image features and PMI. The result of the classification showed that the new method was reliable and effective.

Objective To investigate the effect of plasma homocysteine (Hcy) levels and cognitive dysfunction on patients with type 2 diabetes and explore the other factors that affect cognitive function.Methods 80 patients with type 2 diabetes were selected as our subjects and they were divided into cognitive impairment group (38 cases),cognitive normal group (42 cases) according to a simple mental state scale(MMSE) score.The plasma Hcy,glycosylated hemoglobin,blood lipid,uric acid,24 h urine trace albumin were measured.Results Plasma Hcy concentration in diabetic cognitive dysfunction,non cognitive impairment group and normal control group respectively were(19.56 ± 5.23),(16.21 ± 3.27),(14.67 ± 4.27) tmol/L,and there was statistically significant difference(F =3.76,P ＜0.05).The plasma Hcy levels in diabetic cognitive impairment group was higher than that non-cognitive impairment group(P ＜ 0.05) and normal control group (P ＜ 0.01),The factors impaired cognitive function in patients with other factors included age,glycosylated hemoglobin,body mass index,diabetes duration and plasma Hcy levels,and there were negative correlation with MMSE score (r =-0.336,-0.285,-0.226,-0.392,-0.312 ; all P values were less than 0.05).Conclusion Patient's age,duration of diabetes,glycosylated hemoglobin and BMI can affect cognitive function in patients.Higher Hcy levels in patients with type 2 diabetes is a risk factor for cognitive impairment.
