Objective To analyze the contribution of dietary supplements to current vitamin mineral intakes in Beijing,China.Method By stratified cluster sampling method,3992 subjects aged 18y and above in 1440 households were investigated in 6 different regions in Beijing.Results The dietary intake of vitamin and mineral of men was higher than that of women,but the total intake of niacin and vitamin C was lower.Both dietary and total intake of vitamin and mineral in supplement users were higher that those in nonusers.In the group of supplement users,the contribution of supplement to thiamin,riboflavin and calcium intakes was 60% and 70%,47% and 45%,42% and 45% in men and women respectively.The percentage of supplement users who reached the current recommended intakes of vitamins and minerals was higher compared with that of nonusers,about 20 -30 percent higher for vitamin C and calcium.Conclusion The average intakes of vitamin and mineral are improved by using dietary supplements.Dietary supplements should be included in the future nutrition survey in China for improving the accuracy of nutrient’s intake.

Objective To study the effect of black granule capsules(BGCs) on growth of transplanted mouse hepatocarcinoma cells, cell proliferation cycle and apoptosis.Methods KM mouse were subcutaneously inoculated with Hepatocarcinoma cells (H22) and randomly divided into the model control group, the positive control group, the low, medium and high does of BGC group after 24h. The positive control group received intraperitoneal injection with 30 mg/kg cyclophosphamide. Mice of BGC groups were intragastricaly with different dosage of BGC (400, 800, 1 600 mg/kg). The model control group received intragastricaly with normal saline. The drugs were administrated once a day for seven days. The tumor inhibition rate was calculated at 24 h after the last administration. Flow cytometry was used to detect changes of cell cycle and apoptosis in harvested H22 tumor cells.Results The group of high does showed significant inhibitory effect on the growth of transplanted H22 tumor cells withthe inhibitory rate 38.78% (male) and 43.57% (female). Compared with model control group, groups of different dosages decreased time of G0-G1 phase (58.06% ± 9.65%, 55.10% ± 5.89%, 61.36% ± 15.95%vs. 74.47% ± 2.63%), increased tiem of Sphase (33.96% ± 11.90%, 32.67% ± 4.04%, 33.89% ± 9.82%vs. 14.37% ± 4.92%), and increased the apoptosis rate (31.12% ± 1.85%, 31.89% ± 2.16%, 40.64% ± 0.55%vs.21.75% ± 2.64%).Conclusion BGC has antitumor effect on mouse hepatocarcinoma H22 tumor cells, and its mechanism was to regulate cell proliferation cycle and induce the apoptosis.

ObjectiveTo explore the improvement effect of Flos Puerariae， Hoveniae Semen， and their compatibility on acute alcoholic gastric mucosal injury， and lay a foundation for further development of Flos Puerariae， Hoveniae Semen， and their compatibility in the prevention and treatment of alcohol-induced multiple organ injury. MethodThe acute alcohol-induced gastric mucosal injury model of mice was established by multiple intragastric administration of 56% Hongxing Erguotou liquor （15 mL·kg^-1）. A total of 120 male ICR mice were randomly divided into 8 groups， namely， the blank group， model group， omeprazole group （0.026 g·kg^-1）， Flos Puerariae-Hoveniae Semen （compatibility） high， medium， and low-dose groups （29.2，14.6， 7.3 g·kg^-1）， Flos Puerariae group （19.5 g·kg^-1）， and Hoveniae Semen group （19.5 g·kg^-1）， with 15 mice in each group. After one week of adaptive feeding， the animals were pre-administrated with the corresponding drug at the rate of 10 mL·kg^-1 for 3 d. From the 4^th day， after 1 h of administration， Erguotou liquid was administrated at the rate of 15 mL·kg^-1 and the blank group was administrated with the same volume of deionized water to record the drunkenness and sober up time. The administration was lasted for 3 d. One hour after the last administration， the eyeballs were removed and the mice were sacrificed. The concentration of ethanol in serum was determined by gas chromatograph， and the activity of ethanol dehydrogenase （ADH） in gastric mucosa was determined by ultraviolet-vis spectrophotometer. Hematoxylin-eosin （HE） staining was used to observe the pathological changes in gastric mucosa. Serum inflammatory factors were determined by enzyme-linked immunosorbent assay （ELISA）. The mRNA expression of nuclear transcription factor-κB （NF-κB） p65 and NF-κB inhibitory protein α （IκBα） were detected by real-time polymerase chain reaction （Real-time PCR）. ResultAs compared with the normal group， the content of interleukin-6 （IL-6）， interleukin-1β （IL-1β）， and tumor necrosis factor-α （TNF-α） in serum of mice in the model group was increased （P<0.05）， the mRNA expression of NF-κB p65 in gastric mucosa tissues was increased （P<0.01）， and the mRNA expression of IκBα was decreased （P<0.01）. As compared with the model group， the drunkenness time of the omeprazole group， high and medium-dose compatibility groups， and Flos Puerariae group was prolonged （P<0.05）， the sober up time of the high and medium-dose compatibility groups was shortened （P<0.05）， the ethanol concentration in the serum of the high-dose compatibility group was decreased （P<0.05）， the ADH activity in the gastric mucosa of the omeprazole group and high and medium-dose compatibility groups was increased （P<0.05）， the macroscopic injury score of the high， medium， and low-dose compatibility groups and Flos Puerariae group was decreased （P<0.05）， the score of pathological injury in the omeprazole group， high， medium， and low-dose compatibility groups， and Flos Puerariae group was decreased （P<0.01）， the expression of IL-6 in serum of all drug groups was decreased （P<0.05）， the expression of IL-1β in serum of the omeprazole group， high， medium， and low-dose Flos Puerariae groups， and Hoveniae Semen group was decreased （P<0.05）， the expression of TNF-α in serum of high and medium-dose groups was decreased （P<0.05）， the mRNA expression of NF-κB p65 in gastric mucosa tissues of all drug groups was decreased （P<0.05）， and the mRNA expression of IκBα in gastric mucosa tissues of the omeprazole group and high， medium， and low-dose compatibility groups was increased （P<0.05）. As compared with the high-dose compatibility group， the drunkenness time in the low-dose compatibility group and Hoveniae Semen group was shortened （P<0.01）， the sober up time in the Flos Puerariae and Hoveniae Semen groups was prolonged （P<0.01）， the concentration of ethanol in the serum of the medium and low-dose compatibility groups， Flos Puerariae group， and Hoveniae Semen group increased （P<0.05）， the macroscopic injury score of the medium and low-dose compatibility groups and Hoveniae Semen group was increased （P<0.05）， the pathological injury score of the medium and low-dose compatibility groups， Flos Puerariae group， and Hoveniae Semen group was increased （P<0.01）， the content of IL-1β in serum of low-dose compatibility group， Flos Puerariae group， and Hoveniae Semen group was increased （P<0.01）， and the mRNA expression of IκBα in gastric mucosa of the Flos Puerariae group and Hoveniae Semen group was decreased （P<0.05）.

As compared with the low-dose compatibility group， the pathological injury score of the Hoveniae Semen group was increased （P<0.05）. ConclusionFlos Puerariae， Hoveniae Semen， and their compatibility play a role in preventing and treating acute alcoholic gastric mucosal injury in mice， which may be related to the inhibition of the expression of NF-κB signal pathway in gastric mucosa， and the high-dose compatibility group has the optimal effect.
