Abstract
Mutations of the small heterodimer partner ( SHP) gene have been associated with mild obesity in Japanese subjects. This study was designed to investigate whether there was a similar association in 772 Chinese adults. A total of 272 subjects were normal weight, 423 were overweight and 77 were obese. Four non-synonymous mutations (R34X, H53fsdel10, G171A, G189E) were identified in 10 out of the 500 overweight/obese subjects, but were not seen in the normal weight controls (prevalence 2.00% versus 0.00%, respectively). The relatives of proband carriers, including 25 carriers and 33 non-carriers from three generations, were also screened for 10 multigenerational non-consanguineous pedigrees. A gender-dependent penetrance effect was observed in the pedigrees. Furthermore, the frequency of SHP gene mutations was significantly higher in those with type 2 diabetes compared with the non-diabetics (61.5% versus 28.1%, respectively). These data provide evidence of a gender-dependent effect on penetrance for SHP deficiency and suggest that SHP mutations increase susceptibility to type 2 diabetes.

Abstract
AIMS To investigate the relationship between the maximum grade of skin toxicity, radiation dose and clinical variables in children receiving treatment for sarcomas involving the bone and soft tissue. MATERIALS AND METHODS Between January 2003 and July 2006, 82 patients with musculoskeletal tumours on an Institutional Review Board (IRB)-approved prospective study at St. Jude Children's Research Hospital received three-dimensional conformal or intensity-modulated radiation therapy for local tumour control. Radiation dermatitis was graded according to the National Cancer Institute's Common Toxicity Criteria version 2.0 during and after radiation therapy. The dose to the skin was calculated for each patient from the radiation treatment plan. RESULTS The radiation doses delivered to the primary tumour ranged from 4140 to 7020cGy, with a mean dose of 5040cGy. The maximum recorded grade of skin toxicity was: grade 0: seven patients (8.6%); grade 1: 26 patients (31.7%); grade 2: 37 patients (45.1%); grade 3: 10 patients (12.2%); grade 4: two patients (2.4%). A significant association for increased grade of skin toxicity was observed between dose (P<0.01), volume of skin treated above 4000cGy (P=0.03), use of a bolus (P<0.01), Caucasian race (P<0.01) and related pain (P<0.01). CONCLUSIONS These findings suggest that the delivered dose, use of a bolus, the volume treated, and race may be used in the clinical setting to predict patients at risk for skin toxicity. Alterations in treatment technique and early therapeutic intervention may help to reduce or eliminate radiation-induced skin side-effects and associated pain.

Abstract
BACKGROUND AND AIMS To explore the ability of waist circumference (WC), body mass index (BMI) and waist to hip ratio (WHR) to predict two or more non-adipose components of the metabolic syndrome (MetS) among individuals aged 18-85 in North China. METHODS AND RESULTS This study is a cluster sample survey of 101,510 individuals, complete data are 75,788 subjects, 59,874 males and 15,914 females. Their ages were 51.9+/-12.7 years (males) and 48.7+/-11.5 years (females). Receiver operating characteristic (ROC) analysis was used to examine discrimination and find optimal cut off values of WC, BMI and WHR to predict two or more non-adipose components of MetS. The area under the ROC curve (AURC) for WC (0.694) and BMI (0.692) in females showed no difference. In males BMI (0.657) had a better discrimination than WC (0.634). WHR was weaker in both sexes. The optimal cut off value of WC in males (86.5 cm) was higher than in females (82.1cm); and that of BMI was about 24 kg/m(2) in both genders. The optimal cut off values of WC, BMI, and WHR, increased with age in both sexes. CONCLUSIONS BMI and WC are more useful than WHR for predicting two or more non-adipose components of MetS. Cut off values for WC in males, and those of BMI and WHR in both sexes are lower than that in present MetS criteria; WC in females is slightly higher. Cut off values of WC, BMI and WHR were increased with age in the Chinese.

Abstract
Several sparseness penalties have been suggested for delivery of good predictive performance in automatic variable selection within the framework of regularization. All assume that the true model is sparse. We propose a penalty, a convex combination of the L1- and L∞-norms, that adapts to a variety of situations including sparseness and nonsparseness, grouping and nongrouping. The proposed penalty performs grouping and adaptive regularization. In addition, we introduce a novel homotopy algorithm utilizing subgradients for developing regularization solution surfaces involving multiple regularizers. This permits efficient computation and adaptive tuning. Numerical experiments are conducted using simulation. In simulated and real examples, the proposed penalty compares well against popular alternatives.

Abstract
Since the early days of thermography in the 1950s, image processing techniques, sensitivity of thermal sensors and spatial resolution have progressed greatly, holding out fresh promise for infrared (IR) imaging techniques. Applications in civil, industrial and healthcare fields are thus reaching a high level of technical performance. The relationship between body temperature and disease was documented since 400 bc. In many diseases there are variations in blood flow, and these in turn affect the skin temperature. IR imaging offers a useful and non-invasive approach to the diagnosis and treatment (as therapeutic aids) of many disorders, in particular in the areas of rheumatology, dermatology, orthopaedics and circulatory abnormalities. This paper reviews many usages (and hence the limitations) of thermography in biomedical fields.

Abstract
This study compared the result of percutaneous release using a miniscalpel-needle and steroid injection in 93 trigger thumbs in 83 patients. The patients were randomly assigned to either miniscalpel-needle percutaneous release (group A) or steroid injection (group B). Visual analogue pain scales and patients' satisfaction were evaluated at baseline, 1 and 12 months. One patient in group A and two patients in group B were lost to follow-up. Forty-four of the 46 trigger thumbs in group A and 12 of 47 trigger thumbs in group B had satisfactory results at 12 months. No digital nerve injury occurred in either group. Percutaneous release with a miniscalpel-needle had a higher success rate than steroid injection.

Abstract
Composite tissue allotransplantation (CTA) transplantation is currently being performed with increasing frequency in the clinic. The feasibility of the procedure has been confirmed in over 40 successful hand transplants, 3 facial reconstructions, and vascularized knee, esophageal, abdominal wall, and tracheal allografts. The toxicity of chronic, nonspecific immunosuppression remains a major limitation to the widespread availability of CTA and is associated with opportunistic infections, nephrotoxicity, end-organ damage, and an increased rate of malignancy. Methods to reduce or eliminate the requirement for immunosuppression would represent a significant step forward in the field. Mixed chimerism induces tolerance to solid organ and tissue allografts, including CTA. This overview focuses on the history and expanding applications of CTA as a new frontier in transplantation, and considers the important hurdles that must be overcome through research to allow widespread clinical application.

Abstract
9584 Background: Bleeding is a serious adverse event associated with bevacizumab, a humanized monoclonal antibody against vascular endothelial growth factor (VEGF) used extensively in the treatment of cancer. Currently the overall risk of bleeding remains unclear. This study was conducted to determine the overall risk of bleeding associated with bevacizumab in cancer patients by a meta-analysis of randomized controlled trials (RCT). Methods: Databases from PUBMED and the Web Science from January 1966 until July 2008 and abstracts presented at the American Society of Clinical Oncology (ASCO) conferences from January 2000 to through July 2008 were searched to identify relevant studies. Eligible studies included prospective RCTs in which standard anti-neoplastic therapy was administered with and without the use of bevacizumab with available data of bleeding. Summary incidence rate, relative risk (RR), and 95% confidence interval (CI) were calculated employing fixed- or random-effect models based upon the heterogeneity of the included studies. Results: A total of 13048 patients with a variety of solid tumors from 20 RCTs were included for analysis. Among patients receiving bevacizumab, the incidence of all-grade bleeding was 36.3% (95% CI: 28.0 - 45.5), and the RR was 3.1 (95% CI: 2.4 - 4.1) as compared to controls. The incidence of high grade (grade 3 or above) bleeding with bevacizumab was 2.7% (95% CI: 2.0 - 3.6%), and the RR was 1.8 (95% CI: 1.2 - 2.7). The risk of bleeding varied with the dose of bevacizumab, with RR of 3.0 (95% CI: 2.4 - 3.6) at 5mg/kg/week and 1.6 (95% CI: 1.3 - 2.0) at 2.5mg/kg/week. The risk of bleeding with bevacizumab may vary with tumor type, with higher risk seen in patients with colorectal cancer (RR=6.6, 95% CI: 3.6–12.2) and renal cell cancer (RR=3.7, 95% CI: 2.6–5.5). Bevacizumab is associated with different patterns of bleeding, with epistaxis being the most common. The incidence of all grade epistaxis with bevacizumab was 33.8% (95% CI 24.5–44.6) with a RR of 3.1 (95% CI 2.4 - 4.0). Conclusions: There is a significant increase in the risk of bleeding in cancer patients receiving bevacizumab. The risk may vary with the dose of bevacizumab and tumor type. No significant financial relationships to disclose.
