The metabolic syndrome, a cluster of risk factors for cardiovascular disease, is closely related to environmental and lifestyle risk factors. Increasing evidence suggests that environmental risk factors may involve an increase in xenobiotic exposure, for example due to environmental toxins, medications, high meat intake, food additives and supplements; while lifestyle risk factors, such as sedentary lifestyles, may involve a decrease in the detoxification and elimination of xenobiotics. The skin, the body's largest organ, plays a distinct role in the detoxification and elimination of xenobiotics and the body lipid homeostasis, which is affected by sedentary lifestyle and physical activity, as well as by ambient temperature. Thus, it seems that decreased skin biotransformation and excretion, for example due to low ambient temperature and sedentary lifestyle, may be an important risk factor for metabolic syndrome. This review aims to provide insight into the role of the skin in the development of metabolic syndrome.

The leakage of genetically engineered microorganism(GEM) at the beginning of operation was the important content for ecological risk assessment when GEM was inoculated in a membrane bioreactor(MBR) for bioaugmentation. The effects of different operating conditions on leaking density and intercepting efficiency of GEM were investigated in a submerged microfiltration MBR at the beginning of operation. The interception characteristics were also discussed. The results showed that different operating conditions had different influences on intercepting efficiency:higher sludge concentration was profit for interception,while higher aeration intensity and flux had opposite effects on interception. When the inoculated density of GEM was 1.0?1010 CFU/mL,the leaking densities varied from 1.0?102 CFU/mL to 2.5?102 CFU/mL under different operating conditions at the beginning of operation and the maximum intercepting efficiency could be higher than 8 lg. The main factors determining intercepting efficiency at the beginning of operation were membrane module interception,sludge adsorption as well as suspended GEM transfer inhibition and their contribution shares under certain conditions were 82.3%,14.9% and 2.8%,respectively. Gel layer formation during MBR stable operation was helpful to increase intercepting efficiency. The contribution shares for GEM interception of membrane module,sludge and gel layer were 75.3%,10.7% and 14.0%,respectively,under certain conditions.

According to the characteristics of sludge samples from full-scale wastewater treatment bioreac-tors, the essential total DNA extraction method for most environmental samples, lysozyme-SDS-phenol/ chloroform method, was modified to improve sample pretreatment, intensify cell lysis and enhance the effi-ciency of impurity removal. Obtain a general total DNA extraction method for industrial sludge samples. Such a method was applied for total DNA extraction of sludge samples from several running full-scale an- aerobic or aerobic bioreactors in Shijiazhuang, China. The results indicated that the modified method was suitable for all the sludge samples in this study, showing the satisfying generality. The extracted total DNA of all sludge samples were pure, with about 1.8 of A260/ A280 ratio. The method was also efficient; with average total DNA yield of over 0.7 mg/g and maximum yield of 0.85 mg/g. Moreover, all the extracted to- tal DNA samples could serve as templates directly to amplify 16S rDNA by PCR. The PCR products could be separated well by denaturing gradient gel electrophoresis (DGGE) and the DGGE band patterns were clear enough to be used for further analysis. All these facts indicated that the total DNA extraction method provided in this study could meet the requirements of sludge samples research, from full-scale wastewater treatment bioreactors, using molecular biology technologies.

Objective To evaluate the value of GE′s Q-analysis real-time ultrasonic elastography quantitative analysis software in the diagnosis of breast diseases and explore the best cutoff point of the breast diseases diagnosis.Methods The elastograms of 71 breast lesions(66 patients)were evaluated by using the GE LOGIQ E9 with the Q-analysis software.All the 71 lesions were diagnosed as malignant and benign lesions by surgery or biopsy.The receiver operating characteristic (ROC)curves of the entirety elasticity rate and local elasticity rate was performed.We compared the areas under ROC curves ( AUC) of the two modalities and confirmed the best cutoff point of the breast diseases diagnosis .We also assessed the sensitivity and specificity of the two modalities .Lastly we assessed the ROC curves with Z test to determine whether the difference between the two modalities was significant .Results Among the 71 leisions (66 patients),there were 37 benign lesions and 34 malignant ones.The elastograms of the leisions showed that the elasticity of 37 benign leisions was good ,the hardness value was low and the texture was even .As for the 34 malignant leisions,the elasticity was bad,the hardness value was high and the texture was uneven .The AUC of the local modality was 0.899 ( >0.5).The AUC of the entire modality,was 0.985 ( >0.5).Both modalities were accurate for the diagnosis of breast diseases .When the cutoff point of entirety elasticity rate was set as 3.60,the sensitiveness was 82.4%and the specificity was 86.5%.When the cutoff point of local elasticity rate was set as 2.60,the sensitiveness was 97.1% and the specificity was 91.9%.The difference between the two modalities was significant (Z =2.621,P=0.0088).Conclusions Q-analysis real-time ultrasonic elastography quantitative analysis is able to evaluate the rigidity and texture of tissue and is valuable to distinguish benign breast lesions between malignant breast lesions .The sensitiveness and specificity of local modality are higher than that of entirety modality .

This study was aimed to investigate various factors influencing long-term survival in adult AML patients with fusion gene aml1/eto positive. A single institutional retrospective study with long-term follow-up was performed to better define the prognostic factors for AML patients with aml1/eto positive. Newly diagnosed 89 adult AML patients with aml1/eto positive were followed up for 1 to 42 months (median 24 months) from January 2004 to July 2008. Univariate and multivariate analysis of potential factors influencing survival and prognosis were carried out by using Log-Rank and Cox regression method, including sex, age, initial WBC counts, extramedullary leukemic disease, central nervous system leukemia (CNSL), chromosome aberrations, immunophenotype, first induction regimen, chemotherapy course to complete remission (CR), time from induction therapy to CR, negative or positive rate of aml1/eto and allogeneic hematopoietic stem cell transplantation and so on. The results showed that the estimated 5-year overall survival (OS) and relapse-free survival (RFS) were (50.0 +/- 2.3)% and (47.0 +/- 1.9)% respectively in follow-up of 89 patients for 1 - 42 months (mean 24 months). Univariate analysis revealed that initial WBC counts, CNSL, chemotherapy course to CR, time from induction therapy to CR, persistent negative in remission and allogeneic hematopoietic stem cell transplantation were important prognostic factors for long-term surviva1. Multivariate study demonstrated that initial WBC counts, CNSL, CD56 positive, negative or positive rate of aml1/eto, time from induction therapy to CR, persistent negative result of RT-PCR assay in remission and allogeneic hematopoietic stem cell transplantation were all critical factors in relation to OS and RFS. It is concluded that Chinese adult AML patients with fusion gene aml1/eto positive have some different characteristics as compared with patients from other countries, a relatively poor outcome is observed in patients, HSCT should be recommended to adult AML patients.
