There is a close relationship between high trans fatty acids intake and occurrence of metabolic syndrome. Trans fatty acids intake may lead to metabolic disorders. It affects lipid level, induces visceral obesity and insulin resistance, triggers systemic inflammation, and significantly increases cardiometabolic risks. If the chain of trans fatty acids-metabolic syndrome-cardiovascular disease is understood, a new effective way to prevent metabolic syndrome and cardiovascular events may be provided.

Erectile dysfunction was one of the most frequently postoperative complications after radical prostatectomy,which has been deeply concentrated by patients and urologists,along with more and more people were diagnosed as localized prostate cancer.Widely being used for erectile dysfunction after radical prostatectomy,the efficacy and safety of phosphodiesterase type 5 inhibitors have been confirmed by many clinical studies.However,the influences of phosphodiesterase type 5 inhibitors on the occurrence and progression of cancer are still not completely revealed at present.Additionally,the efficiency of phosphodiesterase type 5 inhibitors on biochemical recurrence after radical prostatectomny is still controversial,though it has been demonstrated that phosphodiesterase type 5 inhibitors is not associated with the occunrence of prostate cancer based on recent clinical studies.We will review the possibly mechanisms of phosphodiesterase type 5 inhibitors in oncologic occurrence,especially in the occurrence of prostate cancer and its biochemical recurrence after radical prostatectomy.

Objective To present 3 cases of neurilemmoma of adrenal gland. Methods The clinical pathological manifestations,diagnosis and treatment of 3 cases of neurilemmoma of adrenal gland were reviewed. Results Tumor resection was undertaken in all the three and the diagnosis was assessed on pathological study. All the 3 patients have been in good condition and tumor free on 3～5 years of follow up. Conclusions Tumor resection is the treatment of choice with good prognosis.Radiotherapy may be considered as an adjuvant treatment for malignant ones.Definite diagnosis depends on pathological studies.

Objective:To determine if growth hormone (GH) and glutamine (Gln) reduce the time and dose of parenteral nutrition (PN) in patients with short bowel syndrome. Methods: Sixteen PN-dependent patients with short bowel syndrome were randomly assigned to Group A (control, oral Gln [0.6 g/kg/d] + GH placebo + diet, n= 5), B (Gln placebo + GH [8 IU/d] + diet, n= 5), and C (Gln + GH + diet, n= 6). PN volume and content were determined by standard criteria based on clinical measurements. After 4 weeks, GH and GH placebo were discontinued, but the diet with Gln or Gln placebo was continued for 12 weeks. Results: Group B showed greater reductions in PN volume, PN calorie and PN frequency than Group A (P

The host protein SAMHD1 has been identified as the first mammalian deoxynucleoside triphosphate triphosphohydrolase (dNTPase), which blocks the infection of HIV-1 in non-cycling immune cells.SAMHD1 protein is highly expressed in human myeloid-lineage cells and resting CD4+T lymphocytes, which restricts HIV-1 replication by hydrolyzing the cellular dNTPs, thus inhibiting reverse transcription and viral complementary DNA ( cDNA) synthesis. Recent studies have revealed that SAMHD 1 plays an important role in virus whole life by promoting HIV -1 genome recombination, degenerating viral genome RNA and restricting virus transmission between cells .In this review, these progress on SAMHD1 research are summarized and the mechanisms by which SAMHD 1 mediates retroviral restriction are analyzed .

AIM: To investigate the effects of ErbB2 overexpression on growth and invasiveness in cultured MCF-7 cell line. METHODS: Retrovirus containing ErbB2 gene was transfected into MCF-7 cells and ErbB2 expression was detected by Western blotting. Proliferation and invasive assays were carried out. Cells overexpressed ErbB2 and its control, AP2, were used in the experiment. RESULTS: ErbB2 was overexpressed in MCF-7 cells after transfection. In vitro, cells overexpressed ErbB2 showed highly proliferated and highly invasive characteristics compared to the control cells. CONCLUSION: Overexpression of ErbB2 promotes cell proliferation and enhances invasiveness in MCF-7 cells. Inhibition of signaling induced by ErbB2 might be a novel strategy for the therapeutics of cancer with ErbB2 overexpression.

[Objective]To improve the preparative method of catilage derived microcarrier and evaluate the micromechanism and biocompatibility of this metarial for injectable tissue engineering cartilage.[Methods]Fresh porcine articular cartilage were obtained and shattered in the iso-osmia liquid in 4℃.After gradient centrifugation,150-300 ?m size cartilage micelles were gathered and were subjected to 1% Triton X-100 once and physiological saline twicely.The structure of specimens were observed and assessed by inverted phase contrast microscopy,environmental scanning electron microscope.And the composition of these specimens were stained with haematoxylin-eosin,safranin-O,toluidine blue and immunohistochemistry of collagen type Ⅱ.The microcarriers were seeded with rabbit bone mesenchymal stem cells(BMSCs) and cocultured with Rotary Cell Culture System(Rotary Cell Culture System,RCCS TM).[Results]The cartilage particles had fiocculus apparence.There were numerous villus on the surface of these cartilage micelles,which were stained positive with the immunohistochemistry of collagen type Ⅱ.The inner part of these cartilage micelles were stained positively with safranin-O and toluidine blue.After coated with BMSCs and cultured in the RCCSTM,the cells grew well on the surface of the cartilage micelles and the latter could be disperse again after blowed with pipette.[Conclusion]The cartilage micelles,which have large surface area and good boicompatibility,is a new kind of microcarrier for injectable tissue engineering cartilage.
