Disease burden of colorectal cancer in Jinchang cohort / 中华流行病学杂志

<p><b>OBJECTIVE</b>To evaluate the disease burden of colorectal cancer in Jinchang cohort, and provide evidence for preventing colorectal cancer and reducing the disease burden of colorectal cancer in the cohort.</p><p><b>METHODS</b>The colorectal cancer mortality data from 2001 to 2013 and the medical records of colorectal cancer patients from 2001 to 2010 were collected for this retrospective cohort study. The colorectal cancer disease burden was described by using mortality rate, standardized mortality rate, medical expenditure, potential years of life lost (PYLL), average potential years of life lost (APYLL), working potential years of life lost (WPYLL), and average working potential years of life lost (AWPYLL). The development trend in disease burden of colorectal cancer was analyzed by using Spearman correlation and the average growth rate.</p><p><b>RESULTS</b>The crude mortality rate of colorectal cancer from 2001 to 2013 was 9.53/100,000 with the average annual growth rate of 12.89%. The PYLL, APYLL, WPYLL and AWPYLL of colorectal cancer were 485.00 person-years, 9.15 years, 253.00 person-years, and 4.77 years, respectively. The direct medical expenditure due to colorectal cancer was 7064.38 Yuan per case and 408.43 Yuan per day. There was no increasing trend in the direct medical expenditure due to colorectal cancer.</p><p><b>CONCLUSION</b>Colorectal cancer mortolity rate was on the rise and it caused heavy disease burden in Jinchang cohort.</p>

Relationship of Plasma TNF-? Levels and Insulin Resistance in the Patients with Type2 Diabetes / 中国医师杂志

Object To investigate the relationship between plasma tumor necrosis factor ?(TNF-?) and insulin resistance in the patients with non obese type 2 diabetes.Methods The levels of plasma TNF-? and serum insulin were measured in 38 patients with type 2 diabetes and 30 healthy subjects by immuno-radioassay. Insulin sensitive index (ISI) and body mass index(BMI) were also calculated. The correlation analysis was done between TNF-? and ISI.Results ⑴ The levels of plasma TNF-? in type 2 diabetes were 30 79?6 64fmol/ml, and higher than those in controls (P
