The psychological and social characteristics of patients referred for NHS cosmetic surgery: quantifying clinical need.

PURPOSE: Elective cosmetic surgery is expanding in the UK in both the public and private sectors. Because resources are constrained, many cosmetic procedures are being excluded within the National Health Service. If guidelines on who can receive such surgery are to be evidence-based, information is needed about the level of dysfunction in patients referred for elective surgery and whether this is related to their degree of physical abnormality. METHOD: Consecutive patients referred to a regional plastic surgery and burns unit for assessment for elective cosmetic surgery completed standardised measures of physical and psychosocial dysfunction, and indicated their perception of the degree of their abnormality and their preoccupation with it. We distinguished between patients referred for physical reasons or appearance reasons only, and compared levels of physical and psychosocial dysfunction in each with published values for community and clinical samples. Surgeons indicated patients' degree of objective abnormality, and we identified the relationship of dysfunction with perceived and objective abnormality and preoccupation. RESULTS: Whether patients sought surgery for physical or appearance reasons, physical function was normal. Those seeking surgery for appearance reasons only had moderate psychosocial dysfunction, but were not as impaired as clinical groups with psychological problems. Patients seeking the correction of minor skin lesions for purely appearance reasons reported excellent physical and psychosocial function. Level of function was related (negatively) to patients' preoccupation with abnormality rather than to their perceived or objective abnormality. CONCLUSIONS: In general, patients referred for elective cosmetic surgery did not present with significant levels of dysfunction. Moreover, levels of functioning were related to preoccupation rather than to objective abnormality. Therefore, for most patients, whether surgical treatment is generally appropriate is questionable. Future guidelines must seek to identify the small minority who do have a clinical need for surgery.

Effect of curcumin on nitric oxide synthase expression in Iipopolysaccharide-activated microglia cells and the anti-oxidative effect of curcumin

BACKGROUND: It has been demonstrated that curcumin can increase the activities of various anti-oxidase in blood and tissue, effectively eliminate various free radicals, reduce the production of peroxisome, and alleviate oxidative stress reaction. Whether it has the same effect on microglia? OBJECTIVE: To observe the effects of curcumin on the expressions of inducible nitric oxide synthase (iNOS), nuclear factor-κB (NF-κB), and superoxide dismutase (SOD) in microglial cell line BV stimulated by lipopolysaccharide (LPS). DESIGN: An observational comparative study. SETTING: Research Room of Biochemistry, Medical College of Nantong University. MATERIALS: Mice microglia cell line BV, iNOS and NF-κB reporter gene plasmids were presented by Dr. Bhat.NR. from the Medical University of South Carolina (USA). Curcumin was produced by the Xi'an Branch of China Chengdu Scholar Bio-Tech. Co.,Ltd.; LPS (E.Coli O26:B6), anti-mice iNOS monoclonal antibody, horseradish peroxidase labeled goat-anti-mice IgG were the products of Sigma Company (USA). METHODS: The experiments were carried out in the Research Room of Biochemistry, Medical College of Nantong University from May 2006 to April 2007. ① Detection of iNOS: The cells were seeded onto 24-well plate at the density of 1×105, After the cells had adhered to the cover glasses, the cells were grouped as negative control group (the primary antibody was replaced by phosphate buffered solution PBS); normal control group (the cells were normally cultured); LPS-treated group (the cells were treated with LPS for 24 hours); curcumin+LPS group (the cells were treated with curcumin for 1 hour and LPS for 24 hours). The expressions of iNOS protein were detected with immunocytochemical staining. ② Determination of iNOS and NF-κB gene activities: According to the introduction of the kit for transfection, iNOS or NF-κB report gene plasmids were transiently transfected with LipofectamineTM2000 liposomes into the cells in the 24-well plate for 24 hours. The cells were divided into normal control group (the cells were normally cultured after transfected with report gene plasmids); blank plasmid group (the cells were normally cultured after transfected with blank plasmids); LPS-treated group (the cells were treated with LPS for 4 hours after transfected with report gene plasmids); curcumin+LPS group (the cells were treated with curcumin for 1 hour and LPS for 24 hours after transfected with report gene plasmids). The content of luciferase in the cell lysis buffer was determined after cell lysis. ③ Determination of SOD activity: The cells were seeded into culture bottle at the density of 1×106, and the divided into four groups, including normal control group (the cells were normally cultured); LPS-treated group (the cells were treated with LPS for 24 hours); curcumin+LPS group (the cells were treated with curcumin for 1 hour and LPS for 24 hours); vitamin C+LPS group (the cells were treated with vitamin C for 1 hour and LPS for 24 hours). The SOD activity was determined with xanthine oxidase and quantitative colorimetric assay. MAIN OUTCOME MEASURES: The expressions of iNOS protein, iNOS and NF-κB, and the activity of SOD were observed. RESULTS: ① Expression of iNOS protein in microglia: The expression of iNOS protein in the LPS-treated group was obviously higher than that in the negative control group (P < 0.01); Those in the curcumin+LPS group were significantly decreased as compared with that in the LPS-treated group (P < 0.01). ② Expressions of iNOS and NF-κB genes: The expressions of iNOS and NF-κB genes in the LPS-treated group were significantly higher than those in the normal control group (P < 0.01); Those in the curcumin+LPS group were significantly lower than those in the LPS-treated group (P < 0.01). ③ SOD activity: The activity of SOD in the LPS-treated group was significantly lower than those in the normal control group (P < 0.01). It in the curcumin+LPS group and vitamin C +LPS group was significantly higher than that in the LPS-treated group (P < 0.01). CONCLUSION: Curcumin could inhibit the expression of iNOS in the activated microglia, and it also has the abilities in eliminating free radicals and antagonizing lipid peroxidation.     

Changing health status and health expectancies among older adults in China: Gender differences from 1992 to 2002

Numerous studies document improvements in health status and health expectancies among older adults over time. However, most evidence is from developed nations and gender differences in health trends are often inconsistent. It remains unknown whether changes in health in developing countries resemble Western trends or whether patterns of health improvement are unique to the country's epidemiologic transition and gender norms. Using two nationally representative samples of non-institutionalized adults in China aged 65 years and older, this study investigates gender differences in the improvements in disability, chronic disease prevalence, and self-rated health from 1992 to 2002. Results from multivariate logistic regression models show that all three indicators of health improved over the 10-year period, with the largest improvement in self-rated health. With the exception of disability, the health of women improved more than men. Using Sullivan's decomposition methods, we also show that active life expectancy, disease-free life expectancy, and healthy life expectancy increased over this decade and were patterned differently according to gender. Overall, the findings demonstrate that China experienced broad health improvements during its early stages of the epidemiologic transition and that these changes were not uniform by gender. We discuss the public health implications of the findings in the context of China's rapidly aging population.
