Objective: To investigate the effects of lycopene on T lymphocyte subpopulations and pulmonary alveolar macrophagic (PAM) functions in rats with acute lung injury (ALI). Methods: Rats were randomly divided into the following groups. (1) Control group, (2) ALI model group, (3) Low dose group, (4) Mid dose group and (5) High dose group. Control group and ALI model group were treated with solvent of lycopene, and the other groups were gastrically incubated with lycopene. Thirty-five days later, control group were given physiological saline, ALI model group and lycopene administrated groups were injected with lipopolysaccharide (LPS) (6.0 mg/kg) to induce ALI. One hour, four hours or six hours after LPS or physiological saline challenged, abdominal aorta blood for measuring lymphocyte subpopulations and bronchoalveolar lavage fluid for measuring function of PAM were gathered respectively. Results: (1) At h 1, the percentages of CD3+,CD4+ and CD8+ of lycopene administrated groups compared with control group were not significantly different. At h 4, the percentage of CD4+ was similar to that at h 1. As for the percentages of CD3+, except high dose group [(28.8?9.9)%] was significantly lower, low dose, mid dose and ALI model group showed no significant difference compared with control group[(39.5?4.5)%]. The percentages of CD8+ of ALI model and lycopene administrated rats, separately (10.2?3.9)%,(10.3?2.8)%,(9.8?2.8)%,(10.1?3.5)%, had been significantly reduced compared with control group[(15.1?2.5)%]; between ALI model and lycopene ad-ministrated groups there was no significant difference. The instance at h 6 was the same as that at h 4. The percentage ratios of CD4+ T-lymphocyte to CD8+ T-lymphocyte of ALI model rats were not significantly different compared with control group or lycopene administrated groups at h 1 and h 6. At h 4, the ratio of the CD4 + and CD8 + in Low dose and Mid dose groups had significant difference and ALI model, high dose hadn’t when they were compared with control group. (2) Lycopene increased the phagocytic function of PAMs significantly at h 1(P

Objective To investigate the effects of ginkgo flavone on the expression of NF-κB and TLR4 in the liver of mice with nonalcoholic fatty liver disease (NAFLD). Methods 120 KM mice were randomly divided into the control group, model group, as well as high, medium and low dosage of ginkgo flavone groups. The animal model of NAFLD in mice was constructed with high fat diet. The pathological changes of liver, liver index , the serum TNF-α, IL-6 , TG , NF-κB and TLR4 in hepatic tissue was observed after 8 weeks of administration. Results Compared with the model group, the level of liver index, serum TG, TNF-α, IL-6 and the expression of NF-κBp65 in the ginkgo flavone groups dramatically decreased 8 weeks after the administration. And the hepatic steatosis was milder. There was no statistical differences in the expression of TLR4 between the ginkgo flavone groups and the control group (P > 0.05). Conclusions These results suggested the closely relationship between TLR4/NF-κB inflammatory pathway and NAFLD. Ginkgo flavone had the therapeutical effects on NAFLD by anti-inflammatory and lipid-lowering action, but no effect was observed on the expression of TLR4 in hepatic tissue.

OBJECTIVE:
To explore the effect of chromosomal translocations on the composition of embryonic chromosomes and its mechanism.
METHODS:
For 52 couples with one partner carrying a chromosomal translocation, results of next generation sequencing of all embryos derived from 61 cycles were divided into different groups based on the type of translocations, gender of the carrier, and maternal age. Effect of parental chromosomal translocations on the composition of embryonic chromosomes of each group was analyzed.
RESULTS:
A significant difference was found between carriers of reciprocal and Robertsonian translocations in terms of proportion of abnormal embryos and structurally normal chromosomes (63.3% vs. 27.5%, and 1.1% vs. 0.3%, respectively). Compared with male carriers, there was an increase in the rate of abnormalities for female carriers (67.2% vs. 58.3% for reciprocal translocations, and 45.5% vs. 13.8% for Robertsonian translocations). The risk for chromosomal abnormality also increased with the maternal age. No significant difference was found in the proportion of abnormal embryos between carriers divided by involvement of acrocentric chromosomes or terminal chromosomal breakpoints.
CONCLUSION
The types of parental translocation, gender of carrier, maternal age, and interchromosomal effect have certain effect on the composition of embryonic chromosomes.
