Papillary thyroid cancer (PTC) is the most common type in thyroid carcinomas.Recently,the prevalence and diagnostic rate of PTC has got significantly high with the general use of ultrasound.Nowadays,more and more studies have suggested that the coexistence of PTC and diabetes is common.They indicated that hyperglycemia would induce the deterioration of oxidative stress injury,chronic inflammation,insulin resistance,obesity,dyslipidemia,deficiency of vitamin D and dysimmunity.All of these may break the balance of oxidation and antioxidation and result in disordering signal pathway,accumulation of inflammatory cytokines,over activating of insulin and insulin-like growth factor-1,changing the metabolic pathways,which will promote the occurrence and progression of PTC.

Traditional Chinese medicine (TCM), an important component of complementary and alternative medicine, has evolved over thousands of years with its own unique system of theories, diagnostics and therapies. TCM has been increasingly used in the last decades and become well known for its significant role in preventing and treating cancer. We believe that TCM possesses advantages over Western medicine in specific aspects at a certain stage of cancer treatment. Here we summarize the advantages of TCM from three aspects: preventing tumorigenesis; attenuating toxicity and enhancing the treatment effect; and reducing tumor recurrence and metastasis.

Objective To make a status survey on type2 diabetic patients with metabolic Syndrome in middle-aged inhabitants.Methods 338 inpatients with type 2 DM including 179 male and 159 female,aged 46?5 years,with complete records in the computer database.Results The prevalent rates of the complications in group of 40～yrs type2 diabetic patients were 17.8% combined with coronary atherosclerotic heart disease,50.9% with hypertension,18.1% with left ventricular dilatation,53.6% with hypertriglyceridemia,46.2% with lower HDL,54.7% with obesity and 38.8% with metabolic Syndrome,respectively.These prevalent rates in the 40-year-old group were all lower than those in groups above 60 years,and the rates was higher in patients whose BMI was above 25(kg/m2).Conclusion There was high prevalence in type 2 diabetic patients with metabolic Syndrome,and was related with the age and obesity.Obesity was an independent risk factor for MS.

Objective To explore the role of oxidative stress in the initiation and development of experimental diabetic nephropathy.Methods Levels of MDA and the total SOD activity were tested in the whole kidney at 1 month,3 months and 6 months of experimental rat diabetes induced by streptozotocin.The pathological changes of diabetic rats were examined by light microscopy.Results The MDA level increased significantly in the diabetic group as compared to control group at all time intervals(2.16?0.57 vs 1.18?0.18,P

Objective To preliminarily investigate the conditions of the performance of chlorine dioxide generator for drinking water disinfection and know the overall situation of the industry.Methods From 2007 to 2008,6 companies'products were chosen for this investigation according to certain rules,and their performance indicators,such as chlorine dioxide output and conversion rate were tested by using the Five-step iodimetry method.Results On-site generating technology was commonly used,and the average conversion rate of the compound type generator was 57.06%,and the pure type generator was 84.78%.Conclusion The conversion rate of the pure type generator is better than the compound type,and the newly invented pure type generator has much better performance and lower disinfection cost.
