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 identify whether soybean isoflavones plays a role in the prevention of chronicallograft nephropathy(CAN)in rats.Methods Forty-five male Lewis rats as receptors were randomly divided into 3 groups,receiving a diet with protein from high isoflavone soy protein fraction (HIS),low isoflavone soy protein fraction(LIS)or casein(CAS)starting one week before renal transplants from fisher donors,and continuing throughout the study.Serial serum and urine samples were collected at the beginning of the study,and at 4th,12th and 24th week.All rats were killed and the grafts were harvested in the 24th week.The functional and histopathogical changes of renal grafts were evaluated.Results In HIS group,arteria caudilis systolic blood pressure(SBP)value,24 h uri- nary protein(Upro)and serum creatitine(Cr)concentrations were significantly lower than those in LIS and CAS groups(all P

[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.

Purpose:Evaluate the operation methods and prognosis following Ivor Lewis subtotal esophagectomy with two-field lymphadenectomy for carcinoma of the middle and lower third of the oesophagus. Methods:From March 1997 to March 2001, A total of 356 consecutive patients underwent Ivor Lewis esophagogastrectomy with two-field radical lymphadenectomy for carcinoma of the middle and lower third of the oesophagus ,The patients received cupula of pleura or cervical esophagogastroanastomosis with mechanical methods through two incisions (right posterolateral thoracotomy and upper abdominal).Results:The post-operative mortality was 0. anastomotic leakages occurred in 3 patients(0.8%). Gastric leaks for stress gastric ulcer occurred in 2 patients (0.6%). Chylothorax occurred in 2 patients(0.6%). Hoarseness occurred in 5 patients(1.4%),4 cases recuperated after 3 months. Barium swallowed postsurgery through anastomosis and pylorus went through smoothly.Full follow-up was 97.2%. Median survival for operative survivors was 2.6 years (range,61 days to 5 years). The overall 3-year survival rate was 74.5% .The overall 5-year survival rate was 55.49%,it was 94.2% for those in stage Ⅰ,81.5% for those in stage Ⅱa,78.3% for patients in stage Ⅱb,36% for those in stage Ⅲ and 0% for patients in stage Ⅳ. Conclusions:Ivor Lewis esophagogastrectomy with two-field radical lymphadenectomy for carcinoma of the middle and lower third of the oesophagus is a safe operation. There is the low post-operative morbidity. Long-term survival have been improved.

Objective To analyze the diagnosis of variant acute myocardial infarction.Methods Clinical datas were retrospectively analyzed in 27 cases with variant acute myocardial infarction.Results 27 patients were diagnosed with myodial infarction by ECG and myocardial enzymea.Conclusion Variant acute myocardial infarction is often misdiagnosed as acute abdomen,cerebral aarterial infarction the disease of neck.but its clinical manifestation especially ECG and myocardial enzymes are changeable,and it needs full analysis,early diagnosis and therapy.
