Objective To investigate the effect of dietary fiber on carbohydrate metabolism of healthy volunteers after the intake of corn starch meal. Methods Totally 12 healthy volunteers aged (25. 8 ± 5. 3) years were enrolled in this study, and they were equally randomly divided into two groups (group A and group B). This was an open, randomized, cross-over, and two-period study, and each period lasted for one day. In period 1, the subjects in group A received fiber-free corn starch and group B received high-fiber corn starch (containing 16 g dietary fiber). In period 2, the two groups are crossed. There was a one-week wash-out time between the two study days. On the study day, breath samples of fasting and 0. 5, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, 4.0, 5.0, 6.0,7. 0, 8. 0 hours post meal were collected to measure13 CO2. Results The delta over baseline at 0. 5, 1.5, 2. 0,2. 5, 3. 0, 4. 0 hour after test meal in fiber free group and in high fiber group were 0. 79, 2. 03, 2. 57, 2. 86,3. 02, 3. 18 and 0. 16, 1. 33, 1.77, 2. 10, 2. 34, 2.42, respectively (the P value was 0. 014, 0. 014, 0. 011,0.018, 0. 036, and 0.020, respectively). Peak concentration of delta over baseline of fiber free group and high fiber group was 3.18 and 2. 56 respectively, there was no significant difference between two groups (P > 0. 05) ,peak time of the group at 4. 0 hour and 3. 5 hour respectively, showed significant difference (P = 0. 032). The cumulative percentage dose recovered 0. 5-6. 0 hours after test meal in fiber-free group and in high-fiber group were 0.41, 1.46, 3.15, 5.50, 8.28, 11.30, 14.42, 17. 62, 23. 65, 28. 78 and 0. 09, 0. 55, 1.61, 3.22,5.23,7.53, 10.09, 12.68, 17.60, 22.27 respectively (the P value was 0.014, 0.018, 0.018, 0.014, 0.013,0.014, 0.018, 0.020, 0.025, and 0.044, respectively). However, there was no significant difference 6.0 hours after meal (P > 0. 05 ). Conclusion The dietary fiber used in this study can delay the absorption of carbohydrate 6. 0 hours within intake without influencing its total absorption amount.

Objective To analyze the relationships between body mass index (BMI), blood pressure and the cerebral vascular function in middle-aged population that underwent health checkup. Methods Participants from health management centers of Renmin Hospital of Hubei province, the Second Hospital Affiliated to Nanhua University, Hospital of Shandong Electric Power and Chinese People's Liberation Army No. 180 Hospital aged 45 to 64 years were selected from health checkup population by cluster sampling. Levels of height, weight and blood pressure as well as the cerebral hemodynamics were checked. Subjects were grouped according to age, BMI, systolic and diastolic blood pressure. The differences and distribution of cerebrovascular function scores (CVFS) between groups were compared and described. Moreover, the risk of stroke in the population was evaluated. Results Of the 17 258 individuals who met inclusion criteria, the abnormal rate (the score below 75 points) of CVFS was 20.9 percent. The CVFS in normal, overweight and obese groups were 91.0±15.4, 83.3±21.3, 70.3±26.5 and differences in all age groups were statistically significant (P<0.01). The CVFS in systolic blood pressure<120,120-139, 140-159,≥160 mmHg (1 mmHg=0.133 kPa) groups were 93.9±12.9, 86.5±18.9, 72.1±23.5, 56.2±25.7 and differences in all age groups were statistically significant (P<0.01). CVFS in normal diastolic pressure<80, 80-89, 90-99,≥100 mmHg groups were 91.0±16.1, 85.5±20.2, 75.4±23.6, 62.7±25.0 and the differences among all age groups were statistically significant (P<0.01). Conclusions The abnormal rate of cerebrovascular function integral and high risk stroke individuals in middle-aged health checkup people was approximately 21 percent. The overweight, obese and the high level of systolic and diastolic pressure may induce the injury of cerebrovascular function and the severity will increase with the level of BMI and blood pressure.

The evaluation of the immunosuppression state in liver transplanted recipients is vital for a correct posttransplantation management and a major step towards the personalized treatment of the immunosuppression.To date,immunological monitoring after liver transplantation relies mainly on clinical judgment and pathological examination of the graft,without a proper assessment of the actual state.Previous studies have ever identified many markers for acute rejection(AR) and immune tolerance after liver transplantation.Many markers for AR are pro-inflammatory or immunoregulatory cytokines and other proteins related to inflammation.However,many markers have been proved to be also able to predict other diseases and only a few of the markers for AR have been validated.Standard liver tests cannot be used as markers for graft rejection due to the low sensitivity and specificity.This review summarized the potential markers for AR and immune tolerance after liver transplantation based on published literatures in recent years and to provide evidence for clinical application.
