2、olic modulation therapy, CMMT）是作者提出的一种全新的肿瘤治疗方法，顾名思义它是采用不同手段调节肿瘤患者正常细胞代谢、干扰肿瘤细胞代谢，从而达到预防和治疗肿瘤的目的。它包含营养疗法，但是内容更加丰富，肿瘤营养疗法是通过营养素实施抗肿瘤治疗，而代谢调节疗法则是通过各种手段调节代谢实施抗肿瘤治疗，这些手段包括（1）营养素调节，（2）能量调节，（3）营养途径调节，（4）药物调节，（5）手术调节，（6）运动调节，（7）心理调节，（8）生物反馈调节。CMMT是另外一种疗法，是一套组合拳，其地位和作用与手术、放疗、化疗等肿瘤传统治疗方法相似，但是代谢调节疗法对机体的损伤更小，毒

Respir Res. 2014;15:80. 12.改善脂肪代谢43BACKGROUND: There is conflicting evidence for the role of statins in the primary prevention of colorectal cancer (CRC). We conducted a case control study (N=357,702) in the non-elderly adult US population (age=18-6
20、4 years) with the primary objective to examine the association between CRC and statin use.PATIENTS AND METHODS: MarketScan databases were used to identify patients with CRC. A case was defined as having an incident diagnosis of CRC. Up to ten individually matched controls (age, sex, region and date
21、of diagnosis) were selected per case. Statin exposure was assessed by prescription tracking in the 12 months prior to the index date. Conditional logistic regression was used to adjust for multiple potential confounders and calculate adjusted odds ratios (AOR).RESULTS: The mean age of participants w
22、as 54 years; 52% males and 48% females. In a multivariable model, any statin use was associated with 26% reduced odds of CRC (AOR, 0.74, 95% confidence interval (CI), 0.72-0.77, p0.001). Age-stratified analyses showed a stronger effect of statins on CRC in participants aged 55 years or younger (AOR,
23、 0.67, 95% CI, 0.63-0.71, p0.001) than in participants aged above 55 years (AOR, 0.79, 95% CI, 0.76-0.82, p0.001); the age-by-statin interaction was statistically significant (p0.001). The dose-response analyses performed with simvastatin only showed a trend towards significance between the duration
24、 of simvastatin exposure and odds of developing CRC (p=0.06).CONCLUSIONS: Statins appears to reduce the risk of CRC in non-elderly US population. Chemoprevention with statin might be more effective in non-elderly US populationSehdev A, Shih YC, Huo D, Vekhter B, Lyttle C, Polite B. The Role of Stati
