Objective To evaluate effects of glucocorticoids on maxillary bone mineral density in rats with acute adriamycin-induced nephrotoxicity (ADR). Methods Forty rats were randomly divided into four groups, control group, glucocorticoids- treated group, ADR group and ADR + glucocorticoids- treated group. ADR group and ADR +glucocorticoids-treated group were given 4 mg/kg adriamycin injection via tail vein to establish ADR model. Control group and glucocorticoids-treated group were given 4 mg/kg saline injection via tail vein. After establishment of ADR model, glucocorticoids-treated group and ADR + glucocorticoids-treated group were intragastric administration of 30 mg/(kg · d) methylprednisolone for 10 weeks, and control group and ADR group were given the same volumes of normal saline. Values of bone calcium pigment (BGP), type Ⅰ collagen, N-terminal pro-peptide (PINP), β-Ⅰ type collagen C-terminal cross-linked telopeptide (CTX) were detected by ELISA. The micro-CT scan was used to measure Tb.Th, Tb.Sp, Tb.N, BVF and bone mineral density (BMD). Results Compared with other three groups, the levels of BGP and PINP were significantly decreased, and CTX were significantly increased in ADR + glucocorticoids-treated group (P<0.05). Micro-CT analysis showed that there was significant maxillae osteoporosis, including changes of porous micro architecture, lower BMD, decreased BVF, lower Tb.Th and widening Tb.Sp in ADR + glucocorticoids-treated group (P<0.05). There was no significant difference in Tb.N between four groups. Conclusion There is imbalanced bone metabolism in rat model of ADR. High-dose hormone therapy can accelerate the occurrence of osteoporosis, decrease bone metabolism, and affect bone structure.

Purpose:To study the effect of EGCG(extracts fr om green tea) on cell cycle in human breast cancer cell line and its mechanism. Methods:Cell proliferation assay kit was used to produce the dose-response curve. Flow cytometric assay was used to evaluate the cell cycle changes on MDA-MB435 cells with and without EGCG. The expression of protein was detected by Western blot. Results:EGCG could inhibit the proliferation of the breast canc er cells MDA-MB-435, 40 ?g/ml EGCG induced G 0 /G 1 phase arrest and the entrance to S phase. Both mRNA and protein level of p21 waf1/cip1 were up regulated in MDA-MB435 cells when treated by 40?g/ml EGCG. Conclus ions:Green tea can inhibit the growth of human breast cancer cells, perhaps by means of p21 and therefore inhibiting the progression of the cell cycle.

Vitamin A plays a significant role in maintaining normal metabolism, cell differentiation, reproduction, vision and anti-infection. As a major food source of vitamin A for infants, the level of vitamin A in breast milk is highly important. Recent studies have shown that vitamin A levels in breast milk varied significantly in different stages of lactation, populations, regions and gestational ages at delivery. Moreover, studies demonstrated that it was also affected by many factors, such as maternal serum vitamin A levels and amounts of supplements during pregnancy, maternal vitamin A intake during lactation, maternal diet, high or low risk pregnancy, and vitamin A reservation in maternal liver. It is vital to understand the level of vitamin A in breast milk and its influencing factors to improve breast-feeding.

AIMTo evaluate the effects of different doses of zinc on the expression of metallothionein isoforms in stressed hippocampal neurons in vitro.
METHODSThe cell stress model was developed by corticosterone. The cultured hippocampal neurons were assigned to seven groups as follows: control group, zinc deficiency group, and their corresponding stressed groups, as well as three different levels of zinc complementarity groups.
RESULTSIn zinc deficiency group, the expressions of metallothionein and MT-1 mRNA, MT-3 mRNA were downregulated. On the other hand, inductions of metallothionein and it's mRNAs in stressed zinc complementarity group were increased. In addition, the levels of supernatant IL-6 and NO were increased clearly in zinc deficiency group and corticosterone stressed groups.
CONCLUSIONOur results suggest that zinc deficiency may decrease while zinc complementarity increase the expressions of metallothioneins and MT-1 mRNA, MT-3 mRNA in stressed hippocampal neurons in vitro.

Both market research and literature reports both found that the ootheca of mantodea was all used as medicine. However, Chinese Pharmacopoeia only records the ootheca of three mantis species. The clinical use of ootheca unrecorded in Chinese Pharmacopoeia, will pose potential risks to drug safety. It's urgent to identify the origin of Mantidis Oötheca. The current researches about original animal in Mantidis Oötheca are based on morphology and unanimous. DNA barcoding fill gaps of the traditional morphological identification, which is widely used in animal classification studies. This study first use DNA barcoding to analyze genetic distance among different Mantidis Oötheca types, align COI sequences between mantis and Mantidis Oötheca and construct the phylogeny tree. The result confirmed that Tenodera sinensis and Hierodula patellifera were the origin insects of Tuanpiaoxiao and Heipiaoxiao, respectively, and Statilia maculate and Mantis religiosa were the origin insects of Changpiaoxiao.
