OBJECTIVETo explore the effect of Danggui Yinzi (DY) on delayed allergy in model mice with qi-blood deficiency syndrome (QBDS).
METHODSQBDS model was established in 48 Kuming mice of SPF grade by using reserpine and acetophenone hydrazine. Forty of them were then randomly divided into the model group, the loratadine group, the high dose DY group, the middle dose DY group, and the low dose DY group, 8 in each group. Another 8 in line with the same standard were recruited as a blank group. Mice in high, middle, and low dose DY groups were administered with DY concentrated solution at 60, 30, 15 g/kg by gastrogavage. Mice in the loratadine group were administered with loratadine solution at 1.66 mg/kg by gastrogavage. Equal volume of normal saline was administered to mice in the model group and the blank group by gastrogavage. All medication was given once per day for 1 successive week. Except those in the blank group, the rest mice were evenly smeared with 1% DNCB solution on the abdomen. Five days after skin allergy, 1% DNCB solution was smeared to right ear of all mice to stimulate allergic reaction. Mice in the blank group were smeared in the same way without allergenic reaction. The auricle swelling and the inhibition ratio were determined at 24 h after attack. Blood was collected from orbit and serum IgE level detected using double-antibody sandwich ELISA.
RESULTSCompared with the blank group, auricle swelling obviously increased and serum IgE level was obviously elevated in the model group (P < 0.01). Compared with the model group, auricle swelling obviously decreased and serum IgE level was obviously reduced in the 3 dose DY groups (P < 0.05, P < 0.01). Meanwhile, the auricle swelling degree was superior in high and middle dose DY groups to that in the loratadine group (P < 0.05). The inhibition ratio of auricle swelling was sequenced from high to low as 67.3% in the high dose DY group, 56.0% in the middle dose DY group, 48.1% in the low dose DY group, 47.3% in the loratadine group.
CONCLUSIONSDY could inhibit auricle swelling and lower serum IgE level. It also could inhibit delayed allergic reaction in model mice with QBDS to some extent.

Objective To explore the effect of long-term depleted uranium (DU)ingestion on testosterone production in rats, and its involvement mechanism. Methods Male and female rats (F0 and F1 respectively) for 160 days, respectively. The contents of testosterone (T), luteinizing hormone (LH), and follicle stimulating hormone (FSH) in serum were detected in 20 months of F0 generations, and 15 months of F1 generations. RT-PCR was used to analyze the levels of StAR mRNA and P450scc mRNA. Results Compared with the normal control group, the testosterone contents in exposed F0 and F1 generations increased, the lowest was 51.73 U/L, but those of LH and FSH decreased. The expression of StAR mRNA in the low-doze group of F1 generation (StAR/β-actin = 1.35) was up-regulated, down-regulated for other groups.compared with the normal control group (P450scc/β-actin = 0. 313), the expression of P450scc mRNA in the low- and high-dose groups of F0 generation were decreased (P450scc/β-actin = 0.21), and those in the low- and high-dose groups of F1generation were increased (P450scc/β-actin = 0.623) (P ≤ 0.01). Conclusion Long-term DU exposure inhibit the male reproduction by intervening the sexual hormone production through down-regulated the expression of StAR mRNA and P450scc roRNA.

Chinese Journal of Contemporary Pediatrics 2010;12(1):17-20
OBJECTIVETo study the changes in hormone levels and the therapy of pituitary hyperplasia secondary to primary hypothyroidism in children.
METHODSThe clinical data of 8 children with pituitary hyperplasia secondary to primary hypothyroidism (5 girls and 3 boys) at ages of 5 to 9 years were studied retrospectively. All of the children had a short stature. They were followed up 1 to 6 years.
RESULTSThe thyroid hormone levels decreased and the serum thyroid stimulating hormone (TSH) and prolactin (PRL) levels increased in the 8 children. After 2 to 6 months thyroxine replacement therapy, the levels of free triiodothyronine (FT3), free thyroxine (FT4) and serum TSH and PRL returned to normal, and the pituitary enlargement regressed to normal in the 8 children. Of them, 6 children's height growth rate increased significantly from 3.1+/-0.5 cm per year to 11.6+/-1.7 cm per year (p<0.01). The other 2 cases had low growth rate and then received additional recombinant human growth hormone (rhGH) therapy. Their height growth rate increased by 11 cm per year. Pituitary hyperplasia did not recur in the 8 children during the follow-up.
CONCLUSIONSThe thyroid function and pituitary examinations are necessary for children with a short stature. Thyroxine substitution therapy appears to be effective for primary hypothyroidism secondary to pituitary hyperplasia. rhGH replacement therapy after regression of the pituitary enlargement can result in a satisfactory height growth in children with low thyroid hormone levels and growth hormone deficiency.

Objective:To determine the inhibitory effect of Rupixiao ( RPX) granule on mammary gland hyperplasia ( HMG) in rabbits and explore the possible mechanism to provide reference for clinical medication. Methods:Rabbit model of mammary hyperpla-sia was established by estradiol benzoate and progesterone. Xiaoyao pills and tamoxifen were used as the positive control, and the RPX granule group was respectively at low, medium and high dose (0. 525,1. 05,2. 1 g·kg-1). Each group was with intragastric adminis-tration for 30 days. The levels of E2 , PROG, FSH, LH and PRL in serum and the expression of VEGF in the homogenate tissue were determined by an Elisa method. The breast tissue of rabbits in each group was withdrawn to observe the structure changes after Hema-toxylin-eosin staining ( HE) . Results:Ovarian preservation-benzoic acid, estradiol combined with progesterone could be used to estab-lish mammary gland hyperplasia in rabbits. RPX granule could significantly decrease the serum levels of E2 and PRL (P<0. 01)and increase that of PROG (P<0. 01 or P<0. 001). The results of pathological section showed that the breast structure in RPX granule high dose group could be restored to the level of the blank control group, which showed its therapeutic effect on HMG was better than that of tamoxifen and Xiaoyao pills. The expression of VEGF in each treatment group significantly decreased compared with that in the model group by the Elisa reagent (P<0. 001). Conclusion:RPX granule has good efficacy in HMG rabbits. The inhibitory effects of RPX granule on HMG in rabbits maybe related to the inhibition of VEGF in rabbit breast tissues, and the inhibition of RPX granule was similar to that of tamoxifen and Xiaoyao pills.

Objective To study the different expressions of receptor activator of nuclear factor-kappa B ligang(RANKL) mRNA in spleens of rats fed with diet of low calcium and high fluoride. Methods A 2× 2×2 factorial design was used and the factors were calcium, fluoride and action time. In the design, 40 Wistar rats [average body mass(118.9±13.5)g] were divided into four groups randomly by weight: control with normal diet (0.790%, calcium), low calcium group with low calcium intake(0.063%, calcium), high fluoride group with normal diet and high fluoride intake(100 mg/L, fluoride) and low calcium and high fluoride group with low calcium and high fluoride intake. After 4 and 8 months, 5 rats of each group were sacrificed and total RNA was extracted from spleen. And the expression levels of RANKL mRNA were determined by reverse transcription polymerase chain reaction (RT-PCR). Results At time of 4 months, the expression level of RANKL mRNA was 0.13± 0.05,0.13± 0.03,0.17±0.02,0.27± 0.05 and at time of 8 months, it was 0.11 ± 0.01,0.16 ± 0.02,0.16± 0.03,0.36 ± 0.07 in control group, low calcium group, high fluoride group, low calcium with high fluoride group, repectively. The factorial design AVONA showed that low calcium and high fluoride had significant effects on RANKL mRNA expression(F = 40.224,56.679, all P < 0.05) while action time had not(F = 2.850, P > 0.05 ). The interactions of low calcium with high fluoride or high fluoride with action time were signifieant(F = 7.247, 18.789, all P < 0.05) while the interaction of high fluoride with action time was not(F = 1.751, P > 0.05). Conclusions Low calcium alone or high fluoride alone or low calcium with high fluoride or low calcium with action time can increase the the RANKL mRNA expression level. High fluoride does not affect the RANKL mRNA level as the action time is prolonged.
