Objective To explore the mechanism of nanometer calcium combined with tonifying kidney herbs on osteoporosis by studying the expression of CaBP-D9K mRNA and protein in the intestinal mucosa of osteoporosis rats due to kidney deficiency. Method The rat model of osteoporosis due to kidney deficiency was established by ovariectomy. Applying the nanometer calcium and nanometer calcium combined with tonifying kidney herbs (big, middle and small dosage) to the rats for 12 weeks, choosing Gushukang, E2 and Gai’erqiD600 as the control drugs. The expression of the CaBP-D9K mRNA and protein in the intestinal mucosa of the osteoporosis rats due to kidney deficiency was determined by the method of RT-PCR and western blotting. Result There was CaBP-D9K and protein expression in the normal rats intestinal mucosa tissue, which plays an important role in the process of the intestinal calcium absorption. The episode of the rat osteoporosis due to kidney deficiency is related to the change of the CaBP-D9K and protein expression and has influence on the intestinal calcium absorption. Conclusion The nanometer calcium combined with tonifying kidney Chinese herbs can stimulate the calcium absorption of intestine, prevent and treat the osteoporosis due to kidney deficiency through regulating the expression of CaBP-D9K mRNA and protein in the intestinal mucosa.

Objective To assess of iron overload in thalassaemia minor patients and provide basis for clinical intervention.Methods A total of 458 thalassaemia minor patients confirmed by genetic tests were divided into two groups(α-thalassaemia group and β-thalassaemia group),and 120 healthy individuals were recruited into control group.Serum iron and serum ferritin were measured,correlations between serum ferritin and age,genotypes,hemoglobin were evaluated.Results There was no significant difference in serum iron among the three groups(P>0.05),but the differences of serum ferritin was statistically significant(P<0.05),and serum ferritin in the β-thalassemia group was higher than that of the α-thalassemia group(P<0.05).Serum ferritin also had significant differences between different age groups(P<0.05),and which was higher in young patients(≤20) and older patients.Besides that,in patients older than 20 years,the level of ferritin was positively correlated with age.Moreover,we found serum ferritin had statistically differences between genotypes in α-thalassaemia patients(P=0.006),and which had poor negatively correlation with hemoglobin in β-thalassaemia patients(r=-0.252,P=0.001).Conclusion Serum ferritin was a sensitive indicator to assess iron overload in thalassaemia minor patients,and which was positively correlated with age in thalassaemia patients 20 or more than 20 years old.Our research also indicates different iron overload traits between α-thalassaemia patients and β-thalassaemia patients.

This study was aimed to observe four kinds of kidney-tonification medicine, which were Epimedium, pso-ralen, Ligustrum lucidum, Polygonum with the active ingredient of icariin, psoralen, oleanolic acid, stilbene glucoside and their orthogonal compatibility. There were two kinds of non-kidney tonification medicine, which were Chuanx-iong and astragalus with the active ingredient of TMP and astragaloside. The observation was made on the regulatory role of rat bone marrow stem cells (BMSCs). A total of 65 SD rats were randomly divided into the normal control group, positive transformed control group, kidney-tonification compatibility group (including Group 1, Group 2, Group 3, Group 4, Group 5, Group 6, Group 7, Group 8, and Group 9), non-kidney tonification medicine control group (in-cluding TMP group and astragaloside group). Intragastric administration of medication was given to the kidney-tonifi-cation compatibility group and the non-kidney tonification medicine control group, once a day for 3 consecutive days. Intragastric administration of equal amount of normal saline was given to the normal control group and the posi-tive transformed control group. On the third day of intragastric administration, rats in each group were sacrificed. Serum containing medication was used in the culture of BMSCs for 6, 12, or 18 days. ELISA method was used to quantitatively detect the expression activity and content of BMP2 on the 6th, 12th, or 18th day, in order to evaluate the degree of bone cell differentiation degree. Real-time quantitative PCR method was used for detection of expression of Bmp2, Smad1, Smad4 mRNA in serum containing medication in the culture of BMSCs on the 18th day. The results showed that the kidney-tonification compatibility can improve the expression activity and content of BMP2 culture in vitro, with the peak on the 12th day. The kidney-tonification compatibility groups can upregulate expressions of Bmp2, Smad1, Smad4 mRNA. It was concluded that the active ingredient compatibility of kidney-tonification medicine can promote BMSCs. Its mechanism may be related to the upregulation of expression of Bmp2, Smad1, Smad4 mRNA, and the activity and content of Bmp2.
