Objective To study the effect of selective COX-2 inhibitor NS-398 on IL-1α and TNF a expression in HaCaT cells induced by UVA/UVB,and further to explore the mechanism on anti human skin photo damage. Methods The subcuhured HaCaT cells were divided into three groups:simple illuminated group was exposed to UVA/UVB directly,NS-398 interfered group was exposed to UVA/UVB after being treated with NS-398 in different concentrations,and the control group was cultured in normal without any treatment.The expression of IL -1α and TNF-α in supernarant was detected by ELISA kit.Results The level of IL-1α and TNF-α expression in supernatant from simple illuminated group was remarkably higher than that in the control group,NS-398 interfered group showed much lower level than the simple illuminated one,and the expression of IL-1α and TNF-α was dependent on the concentration of NS-398.Conclusions NS-398 can reduce IL-1α and TNF-α expression in HaCaT cells induced by ultraviolet rays,suggesting the possibility of anti human skin photo- damage effect.

BACKGROUND: Nasal alar cartilage constitutes the main component of the lower 1/3 of the nose, that is, nose tip, nose wing, and nasal columella, its structure has a decisive role on the nose shape, especially the tip of the nose shape. The intensive study on nasal alar cartilage will help deepen our understandings of nasal alar cartilage morphology, structure and function, and help clinicians to correctly handle the lesions of nose and the lower part and to carry out medical beauty. OBJECTIVE: By observing external nasal anatomy, to clarify the histological role of nasal alar cartilage on nose shape, especially the nasal tip shape.DESIGN, TIME AND SETTING: Experimental observation of repeated measurement was conducted at the Laboratory of Anatomy, Second Military Medical University of Chinese PLA from September 1~(st) to 26~(th), 2006.MATERIALS: Well-preserved bodies of 15 fresh adult, containing 10 males and 5 females were used in this study.METHODS: To fully observe the fine structure of external nose, 30 sides of 15 external noses were dissected, and autopsy started from the medium dorsum of nose, layered anatomy, to observe various layers and the characteristics of the layers with blood vessels, focusing on observation of in vitro pre - and free post-nasal alar cartilage morphology, and measurement and recording were performed.MAIN OUTCOME MEASURES: Big foot medial alar cartilage, lateral feet and the angle of inside and outside legs were measured.RESULTS: Alar cartilage was open for a pair of backward "u"-shaped thin cartilage plate, and lateral nasal cartilage was located below and anteriomedialis the nose, was composed of medial and lateral crus and fornix, with thin body shape, unfixed structure. The shape of fornix was difficult to accurately describe; most presented wavy or folded. Lateral crus presented diamond-shaped or long strip, (16.21±2.71) mm in length, (8.45±1.72) mm in width, (1.09±0.18) mm in thickness. Cephalic rim intersected lower edge of lateral nasal cartilage, and slightly covered the lower edge of the lateral nasal cartilage, so that the two were overlapped, but also only the intersection without overlapping. Lateral crus constituted the base of nasal wings. Narrow medial crus formed nasal tip and the frame of front nasal columeila, showing posteroinferior curve or S shape, (13.06±2.16) mm in length, (3.79±0.58) mm in width, (1.02±0.18) mm in thickness. The left and right medial crus in the middle were connected by connective tissue, and in the same way connected to the anterior margin of the lateral nasal cartilage. Medial and lateral crus in the nasal tip showed an acute angle intersection, its angle (75.25±11.17)°. The medial and lateral crus intersected in the nasal tip and formed the fomix of the greater alar cartilage. The bilateral cornix constituted the frame of the nasal tip. CONCLUSION: Meager nasal alar cartilage is composed of the medial crus, lateral crus and fornix, which determined the nose shape, especially the nasal tip shape. External nose plastic surgery should pay attention to the protection of nasal alar cartilage.

Objective To investigate the susceptibility ofepidermal cells to ultraviolet A(UVA)-induced apoptosis in dopachrome tautomerase knockout Dct~(-/-) mice versus wildtype C57BL/6J mice.Methods High titer of anti-Ro/SSA-positive sera collected from three patients with SLE and typical cutaneous phntosensitivity were intraperitoneally injected into both Dct~(-/-) and wildtype mice,which were then chronically exposed to UVA irradiation at a single dose of 10 J/cm~2 three times a week for two weeks.Then,UVA-irradiated tail skin was excised from each mouse,embedded with paraffin,cut into 4 to 5-μm sections followed by hematoxylin/eosin staining and terminal deoxynucleotidyl transferase nick end labeling(TUNEL),respectively,for the counting of sunburn cells(SBC) and apoptotie cells.Results After chronic UVA exposure,the number of SBC and TUNEL-positive cells per 100 epithelial cells was significantly higher in serum-injected Dct~(-/-) mice than in serum-injected wildtype mice(14±1.0 vs 7±-0.6,62±2.7 vs 30 ±1.6,both P<0.05).A significant decrease was also observed in the number of SBC (6 ±0.9 per 1 00 epithelial cells)and TUNEL-positive cells (42±2.5 per 100 epithelial cells)in uninjected Dct~(-/-) mice compared with those of serum-injcoted Dct~(-/-) mice(both P<0.05).Conclusions The deficiency of Dct gene increases the susceptibility of epidermal cells to UVA-induced apoptosis under the presence of anti-Ro/SSA antibody,which potentially contributes to the develop-ment of anti-Ro/SSA antibody-mediated photosensitivity in SLE.

Objective To study the effect of selective COX-2 inhibitor NS398 on IL-10 and IFN-γexpression in human keratinocytes induced by UVA,and further to explore the effect on anti human skin photoaging.Methods HaCaT cells were divided into three groups:simple UV exposure group,NS398-intervene group and blank group.For UV radiation,simple UV exposure group and NS398-intervene group were irradiated with UVA at a dose of 30 J/cm2.In order to assess the effect of NS398,HaCat cells were treated with NS398 at the dose of 0,20,40,80μmol/L respectively and then incubated without irradiation for 2h,substrate changed and cultured for 24h,and then the expression of IL-10 and IFN-γ mRNA was detected via RT-PCR.Results Simple UV exposure group had obviously higher expression of IL-10 mRNA and lower expression of IFN-γ mRNA than that of control group,while NS398-intervened group had significantly lower expression of IL-10 mRNA and higher expression of IFN-γ mRNA than that of simple UV exposure group,and dose-dependency existed.Conclusions NS398 may delay photo-damage of human skin via inhibiting the expression of IL-10 mRNA and up-regulating the expression of IFN-γ mRNA in human keractinocytes.

BACKGROUND: Diabetic cardiomyopathy, a serious complication of diabetes, is an important factor of increased mortality in patients with diabetes. Therefore, providing an effective experimental animal model is particularly important for studying the pathogenesis and treatment methods of diabetic cardiomyopathy. OBJECTIVE:To explore the method of establishing Wistar rat models of diabetic cardiomyopathy. METHODS:Forty rats were randomly divided into the control group (n=10) and diabetic cardiomyopathy group (n=30). The rats in the diabetic cardiomyopathy group were intraperitonealy injected with 60 mg/kg streptozotocin at a time to establish rat models of diabetic cardiomyopathy. The rats in the control group were given the same dosage of citric acid buffer by the same way. The rats in these two groups were al fed with non-fat high-sugar normal diet. RESULTS AND CONCLUSION:Compared with the control group, after 3 weeks of injection with streptozotocinin in rat models of diabetic cardiomyopathy, blood glucose level was significantly increased, myocardial cels arranged in disorder, the nuclei were of different sizes, colagen content in the myocardial tissue was significantly increased, and colagen fibers were thick and disordered. In addition, the mRNA and protein levels of transforming growth factorβ1 and type I colagen, two indices reflecting myocardial fibrosis, were markedly increased. These results indicate that intraperitonealy injecting large doses of streptozotocin (60 mg/kg) at a time and feeding with non-fat high-sugar normal diet could establish a stable rat model of type 1 diabetic cardiomyopathy. This method is safe and effective with high feasibility.
