Objective To observe the effect of resveratrol on arterial remodeling in spontaneous hypertensive rats.Methods Spontaneous hypertensive rats (SHRs, n=20) and Wistar-Kyoto rats (WKYs, n =10) were randomly assigned to three groups: control group, model group and resveratrol group.Systolic blood pressure (SBP) and pulse wave velocity (PWV) of the three groups was observed.Morphological observations were obtained by hematoxylin and eosin or victoria blue and picrosirius red.The content of nitric oxide (NO) and endothelin-1 (ET-1) were determined to assess the endothelial function.Oxidative stress was assessed by malondialdehyde (MDA), hydrogen peroxide (H2O2) , and activities of antioxidant enzymes superoxide dismutase (SOD) and catalase (CAT).Results Compared with control group, SBP, PWV, wall thickness, wall-lumen ratio,vascular cross-sectional area (VCSA), luminal cross-sectional area (LCSA) and collagen-elastic ratio were increased, and the levels of NO, SOD, CAT in rat aortic tissues were decreased, while ET-1,MDA, H2O2 levels in rat aortic tissues were enhanced in model group at the end of 22 weeks.After the treatment of resveratrol, SBP had no significantly difference between model and resveratrol groups, while PWV, aortic wall thickness, wall-lumen ratio, VCSA, LCSA and collagen-elastic ratio were decreased in resveratrol group as compared with model group [(6681.1 ± 2154.9) cm/s vs.(4283.1±946.1) cm/s, (234.7±51.8) μm vs.(123.4±21.5)μm, (10.3±2.3) ％ vs.(5.8±1.4) ％, (6.4±0.4) mm2 vs.(4.8±0.6) mm2, (4.1±0.1) mm2 vs.(3.2±0.4) mm2, (1.1±0.3) vs.(0.4±0.2), P＜0.05 or 0.01].Compared with model group, the expressions of NO, SOD, CAT in rat aortic tissues were increased and levels of ET-1, MDA, H2 O2 in rat aortic tissues were decreased in resveratrol group after treatment of resveratrol (P＜0.01 or P＜0.05).Conclusions Resveratrol has an antioxidant effect, and it could attenuate arterial remodeling by improving oxidative stress.

Objective To explore the susceptibility of Candida albicans biofilms to micafungin. Methods In vitro model of C. Albicans biofilm was established in 96-well microtiter plates with 30 C. Albicans isolates from the Department of Mycology, Changhai Hospital, Shanghai. The susceptibility of C. Albicans biofilms to fluconazole, amphotericine B and micafungin was evaluated by colorimetric XTT-reduction assay. Sessile MIC80 (SMIC80), defined as the lowest antifungal concentration at which an 80% reduction in fungal growth was achieved, was determined. Results Of the 30 C. Albicans isolates grown in sessile states, all were resistant to fluconazole (SMIC80≥64 μg/mL), 4 sensitive to amphotericine B (SMIC80≤1 μg/mL), 26 resistant to amphotericine B (SMIC80 > 1 μg/mL), 27 sensitive to micafungin (SMIC80 < 16 μg/mL), 3 resistant to micafungin (SMIC80 >16 μg/mL). Statistical analysis revealed a significant difference in the activity against C. Albicans biofilms between micafungin and fluconazole (χ2=736.36, P<0.01), micafungin and amphotericine B (χ2=529.95, P<0.01), but not between anphotericine B and fluconazole (χ2=2.29, P>0.05). Conclusion C. Albicans biofilms are resistant to routine antifungal agents such as fluconazole and amphotericine B, but relatively more sensitive to micafungin.

Objective To investigate influence of hyperlipidemia in parents on plasma lipid level,blood pressure,body mass index(BMI) and waist circumference(WC)of their children.Methods Eighty children whose parents had been with hyperlipidemia(Group A) and 893 children whose parents had been normal plasma lipid levels(Group B) were studied.BMI,systolic pressure(SP),diastolic pressure(DP),WC,plasma triglyceride(TG),cholesterol(CH),high density lipoprotein-cholesterol(HDL-c),low density lipoprotein-cholesterol(LDL-c)of two groups were measured and compared.Results The levels of BMI,TG,TCH,LDL-c,SP,and DP had a increasing trend in group A compared to those of group B.HDL-c in group A had a decreasing trend compared to that of group B.But only the increase of BMI is significant(P

20 was lower than those whose BMI≤20(P

BACKGROUND: More and more patients with periodontal disease require orthodontic treatments. Thus, the remodeling process and its mechanism of inflammatory periodontal tissues become a hot point during orthodontic tooth movement.OBJECTIVE: To observe the remodeling of inflammatory periodontal tissues during orthodontic tooth movement.METHODS: A total of 50 Sprague Dawley rats were randomly divided into the control and periodontitis groups. In the periodontitis group, rats were established periodontitis models. After that, all rats were prepared for orthodontic tooth movement models. The remodeling of periodontal tissues was observed by hematoxylin-eosin staining at 1, 3, 5, 7 and 14 days after orthodontic tooth movement.RESULTS AND CONCLUSION: The movement distance of the periodontitis group was greater than that of the control group. At 0-7 days after orthodontic force application, there was obviously bone resorption at the pressure side and the bone formation was inhibited at the tension side; at 14 days after force application, the bone resorption was diminished, associated with large numbers of multinucleated osteoclasts at the pressure sides in both groups. The findings showed that rats with periodontitis suffered more periodontal traumatism during orthodontic tooth movement, thus, treatment should be delayed until the inflammatory signs were controlled and the local inflammatory was eliminated.

Objective To discuss the mechanism and characteristics of clinic presentation and neuropathology in idiopathic hypereosinophilic syndrome (IHES) encephalopathy. Methods IHES encephalopathy was diagnosed by clinical presentations,lab examinations,neurologic images,marrow and brain biopsy,then treated with corticosteroids and continuous follow-up. Results The IHES patient presented progressive limbs weakness and cognitive deficit with elevated eosinophil count. Results of lab examinations and bone marrow biopsy ruled out secondary eosinophilia and clonal eosinophilia such as eosinophilic leukemia.Brain magnetic resonance imaging (MRI) study showed multiple lesions in right frontal lobe, bilateral parietal and occipital lobe, presenting hypointensity in T1 weighted images,hyperintensity in T2 and fluid-attenuated inversion recovery weighed images. Brain biopsy showed proliferation of vascular membrane,small vessels stenosis,ischemia-induced morphological change and necrosis of neurons in the lesions.The patient was continuously treated with corticosteroids,and the situation was stabilized with follow-up.Conclusions IHES encephalopathy should be paid more attention in clinical practice of neurologists for its rarity. Brain vascular damages caused by elevated eosinophil may be an important pathophysiological mechanism of IHES encephalopathy,and corticosteroids or hydroxycarbamide should be used for the treatment.

Objective To explore the role of Beclin 1 and PTEN in gastric caicinoma genesis and the effects on prognosis.Methods The expression of Beclin 1 and PTEN in 199 gastric caicinoma specimens and corresponding adjacent noncancerous tissues were examined by tissue microarrays and immunohistochemistary,and the relation with gastric cancer was analyzed.The rate of Beclin 1 and PTEN expression in 15 fresh gastric carcinoma samples and corresponding adjacent noncancerous tissues were detected by Western blot.All the samples were from Changzheng Hospital.Results The Results of immunohistochemistary showed that the rates of Beclin 1 and PTEN positive expression in cancinoma tissues were 47.2％ (94/199) and 55.8％ (111/199),both were lower than that of adjacent noncancinoma tissues (94.5％,188/199 and 92.5％,184/199; P ＜ 0.01).The lower expression of Beclin 1 and PTEN in gastric carcinoma were associated with gender,differentiation degree,depth of tumor invasion,lymph node metastases and disease stage(P＜0.05).There was a positive correlation between Beclin 1 and PTEN expression in gastric carcinoma tissues (r =0.680,P＜0.01). The survival analysis indicated that Beclin 1 and PTEN were independent factors in determining the prognosis of gastric cancinoma patients.The 5-year survival rate of Beclin 1 positive patients was 67.0％ (63/94),and of negative patients was 33.3％ (35/105).The 5-year survival rate of PTEN positive patients was 71.2％ (79/111),and of negative patients was 21.6％ (19/88) ( all P＜0.001).The Results of Western blot indicated that the expression of Beclin 1 and PTEN in gastric carcinoma tissues were significantly lower than that in the adjacent noncarcinoma tissues ( all P＜0.001).Conclusion The abnormal expression of Beclin 1 and PTEN may be related to carcinogenesis and the development of gastric carcinoma.
