Objective To investigate the effect of milk basic protein (MBP) on bone metabolism in normal and ovariectomized (Ovx) rats. Method Forty-eight female Sprague-Dawley rats were ovariectomized and another 12 rats received sham operation (Sham). After 10 d recovery period, the Ovx rats were randomly divided into 4 groups: control, low-dose, medium-dose, and high-dose MBP group. Another 44 normal female rats without ovariectomy were also divided into 4 groups as above. The MBP dosages for each group were respectively 0, 10, 20, 30 mg/kg bw. All rats were i.g. administered for 90 d. Bone mineral density (BMD) of the femur (at proximal end, middle of diaphysis, and distal end) was measured by dual-energy X-ray absorptiometry in vivo. The amounts of calcium, magnesium and phosphorus were analyzed by ICP-AES. Results BMD at distal end of femur was significantly higher in normal low-dose group than in normal control group while no significant effect was observed in Ovx MBP groups. As for the amounts of calcium, magnesium and phosphorus, there were no significant differences among normal experimental groups and also among Ovx experimental groups. However, some variations in the level of those minerals were observed. Conclusion MBP at 10 mg/kg bw significantly elevated BMD at femoral distal end in normal rats, while no similar effect was observed in Ovx rats. Besides its influence on bone minerals, there may be another mechanism involved in its effect on bone metabolism.

OBJECTIVE:To optimize the ethanol precipitation condition for Shaoshi hujing capsules.METHODS:The content of Paeoniflorin in ethanol precipitated solution was determined by HPLC.Effects of three factors-relative density of water decoction before decoction,concentration of ethanol and time of reaction on the content of paeoniflorin in the ethanol precipitation were investigated by orthogonal design.RESULTS:The relative density of water decoction before decoction had a significant impact on ethanol precipitation(P

Objective.To probe into the influence of Jiannao Anshen Capsule of Miao medicine on the behavioral performance,content of cytokine interleukin-1 (IL-1),neuroendocrine hormone melatonin (MT) and monoamine neurotransmitter 5-hydroxytryptamine (5-HT) of rats with sleep deprival.Methods All of the 60 rats were evenly and randomly divided into 5 groups:the normal control group,model control group,estazolam group,Zaoren Anshen group,and Jiannao Anshen of Miao medicine group,respectively.Every group had 12 rats.Sleep deprivation rat model was established by intraperitoneal injection of para-chlorophenyla lanice (PCPA).After successful modeling,the rats were intragastrically administrated with corresponding medicines.The contents of serum 5-HT,IL-1 and MT and the contents of 5-HT,MT in brain tissue were determined.Results Behavioral score,the contents of 5-HT,MT and IL-1 in serum and the contents of 5-HT,MT in brain tissue in insomnia rats caused by PCPA were significantly decreased as compared with normal control group (P ＜ 0.05).In the Jiannao Anshen group,estazolam group and Zaoren Anshen group,the behavioral score,the content of 5-HT,MT and IL-1 in serum and the content of 5-HT and MT in brain tissue of insomnia rats were significantly increased as compared with model control group (P ＜ 0.05).The behavioral score,the content of 5-HT,MT and IL-1 in serum and the content of 5-HT and MT in brain tissue of insomnia rats were not statistically significant different among Jiannao Anshen group,estazolam group and Zaoren Anshen group (P ＞ 0.05).Conclusion Jiannao Anshen capsule of Miao medicine could obviously improve the sleep quality of rats with sleep deprival.The mechanism may be related to improving the content of IL-1,MT and 5-HT.

Objective To evaluate the influence of different field-strength magnets(1.5 T and 3.0 T)on MRI artifacts caused by Ni-Cr alloy fixed prostheses.Methods The crown,bridge and upper denture fixed prostheses with different thickness were produced by Ni-Cr alloy as test samples,and were one by one put on the centre of water phantom for MR scanning with different field-strength magnets(1.5 T and 3.0 T).The artifact areas on these two field-strength magnets were measured and statistically compared.The plastic prostheses with the same shape and thickness as the test samples were served as controls.Results Ni-Cr alloy fixed prostheses could cause MRI artifacts,and the artifact areas increased with the mass of prostheses.However,no artifact area was found in controls.Compared with those on 1.5 T magnet,the MRI artifact areas significantly increased on 3.0 T magnet(P

As an indispensable part of minority traditional medicine, mineral medicine has used with less dosage and reliable efficacy for the last thousand years. Based on the unearthed relics and medical literatures of past dynasties, the history of Han nationality ap- years, which had been recorded in main literature. But there is less comprehensive report of its usage in the other 55-minority nationality. This article was based on the analysis of ethnic minority literature of thousands of years, and conducted a comprehensive collation and analysis of mineral medicine. It was mostly determined that there was 20 minority groups using mineral medicine, with a total of 163 species (limited our references), and the most used is the Tibetan, accounting for 141. The most serious problems of mineral medicine are that species should be further investigated and researched, and then become the legal commercial medicine, and the classification principles of mineral medicine should be established. Through the traditional processing and experimental studies, the problems of attenuation and detoxification should be solved.

Objective The study of loss of heterozygosity (LOH) on chromosome 1p36 was performed to locate the deletion areas probably harboring tumor suppressor genes in invasive ductal breast carcinoma not otherwise specified (IDC NOS).Methods Eighty paired breast cancer/normal tissue DNA samples were examined for LOH on chromosome lp36 using eight polymorphic microsatellite (MS) loci.The PCR products were electrophoresed on 8％ denatured polyacrylamide gel and stained using silver staining.Finally,the data were analysed and compared with the clinicopathological parameters using statistical analysis.Results In 80 IDC NOS,LOH was identified in 45 cases (56.3 ％) at least in one MS locus.MS locus D1S1310 showed the highest rate of LOH [35.7％ (25/70)].Conclusion Chromosome 1p36 might be the highly deleted region.The results of this study indicate that the chromosomal regions 1p36.23-33 might contain tumor suppressor genes associated with human breast carcinomas.

As one of the risk factors for atherosclerosis,human cytomegalovirus infection has received increasing attention,while cytomegalovirus infection of vascular endothelial cells is considered as the initial stage of causing atherosclerosis.Therefore,elucidating the mechanism of human cytomegalovirus infection of vascular endothelial cells will help further confirm the viral and etiological theories of atherosclerosis,and may block its occurrence and development from the initial stage of infection.
