OBJECTIVETo explore the protection on apoptosis and the mechanism of promoting the cytoactive of osteoblast by Morinda Root Polysaccharide through the observations of the cultured osteoblast in vitro.
METHODSPrepared blood serum with Morinda Root Polysaccharide and Morinda Root aqueous extract and cultured Osteoblast in vitro with it. The second generation osteoblasts in vitro were separated from the cranium of 24-hours newborn SD rat, which were divided into control group (adding only rat serum during cultivation), induction apoptosis group (adding trans-retinoic acid in control group), Morinda Root aqueous extract group (adding serum prepared by Morinda Root aqueous extract in induction apoptosis group) and Morinda Root Polysaccharide group (adding serum prepared by Morinda Root Polysaccharide in induction apoptosis group). Adopting fluorescence microscope, apoptosis detected by flow cytometry and gene expression of Bcl-2 and Bax detected by RT-PCR, to evaluate the effect of Morinda Root Polysaccharide on the course of osteoblast apoptosis.
RESULTSThe apoptotic rate of Morinda Root aqueous extract group and Morinda Root Polysaccharide group were significantly lower than that of induction apoptosis group (P < 0.01). The apoptosis ratio of Morinda Root Polysaccharide group was lower than that of Morinda Root aqueous extract group (P < 0.05). Expression level of Bcl-2 mRNA of apoptosis cell: control group > Morinda Root Polysaccharide group > Morinda Root aqueous extract group > induction apoptosis group (P < 0.01). Expression level of Bax mRNA: induction apoptosis group > Morinda Root aqueous extract group > control group > Morinda Root Polysaccharide group (P < 0.01). Bcl-2/Bax: control group > Morinda Root Polysaccharide group > Morinda Root aqueous extract group > induction apoptosis group (P < 0.01).
CONCLUSIONMorinda Root can inhibit the apoptosis of osteoblast induced by trans-retinoic acid in some extent. The above role of Morinda Root Polysaccharide is significant better than that of Morinda Root aqueous extract. It is indicated that Morinda Root Polysaccharide is one of the essential component of inhibiting osteoblast apotosis.

OBJECTIVETo investigate the optimum phase and dose of pharmaco-serum of diabetic rats fed with Qianggubao decoction ([Chinese characters: see text]) on the differentiation and mineralization of osteoblast (OB). METHODS (OB) was isolated from the skull of 10 newly born SD rats aged 1 to 2 days by means of Trypsin-collagenase digestion. After the OB was identified, different kinds of pharmaco-serum of diabetic rats fed with inactive Qianggubao decoction ([Chinese characters: see text]) of different phase (rats were fed with medicine three days or five days after last fed with medicine one hour or three hours) and concentration (5%, 10%, 20%) were added to the OB and incubated. After 7 days and 18 days of culture,the effects of the differentiation and mineralization of osteoblast were detected.
RESULTSThe secretion of ALP and formation of mineralized nodules of osteoblast in the different doses of pharmaco-serum groups were almost the same as that of normal control group, but were superior to that in the model control group. And the group with concentration of 20% pharmaco-serum was the best in the secretion of ALP and formation of mineralized nodules of osteoblast. As to the phases of pharmaco-serum, the best one on the differentiation and mineralization of osteoblast was the serums from diabetic rat-model fed with Qianggubao decoction ([Chinese characters: see text]) three days or five days, after one hour of last fed with medicine.
CONCLUSIONThe pharmaco-serum of diabetic rats fed with Qianggubao decoction ([Chinese characters: see text]) can promote the differentiation and mineralization of osteoblast. Allow for time and the cost of experiment,we presume that pharmaco-serum of diabetic rats fed with Qianggubao decoction ([Chinese characters: see text]) three days, after one hour of last fed, with concentration of 20% and not-inactivation is the optimum on the differentiation and mineralization of osteoblast.

OBJECTIVETo observe the intervention effect of Leihong Granule (LG) in in-stent restenosis (ISR) after endovascular therapy for lower extremity arterial occlusive diseases (LEAOD).
METHODSRecruited 80 LEAOD patients who successfully underwent endovascular therapy (balloon dilation and stent implantation) were randomly assigned to two groups, the control group and the LG group, 40 in each group. Patients in the control group received basic treatment, while those in the LG group additionally took LG for 3 months. Plasma levels of IL-10, IL-18, CRP, and the intima-media thickness (IMT) of lower extremity artery were observed in the two groups between and after treatment. The rate of stent patency, ABI, intermittent claudication, rest pain, and the incidence of amputation the two groups were recorded and observed in the two groups.
RESULTSIn the control group, serum levels of IL-10, IL-18, CRP, and IMT were significantly higher one month after surgery than before surgery (P < 0.05). There was no significant difference in serum levels of IL-10, IL-18, CRP, or IMT between the two groups before surgery (P > 0.05). These indices were obviously lower in the LG group than in the control group after surgery (P < 0.05). Compared with the control group, the incidence rates of intermittent claudication and the rest pain at 6 months and 12 months after surgery significantly decreased (P < 0.05). The stent patency rate at 6 months and 12 months after surgery, and ABI were significantly higher than those of the control group (P < 0.05). There was no statistical difference in the amputation rate between the two groups (P > 0.05).
CONCLUSIONLG might effectively improve ischemic symptoms of affected limbs possibly through lowering the ISR rate after endovascular therapy for LEAOD through preventing immunosuppressive actions.

Objective The nerve-protective effect of Apoli-poprotein J ( ApoJ) in intracerebral hemorrhage ( ICH) is not yet clarified.This study aimed to explore the therapeutic effect of trans -plantation of bone marrow mesenchymal stem cells (BMSCs) carrying the ApoJ gene on intracerebral hemorrhage in rats and its possible ac -tion mechanism. Methods Rat BMSCs were isolated, cultured in vitro, and transfected with the recombinant plasmid pEGFP -N1-ApoJ mediated with lipofectamine.Ninety-six SD rats were randomly divided into groups A, B and C, and ICH models were established by two -step autologous intracranial blood injection .At 24 hours after model-ing, the rats in groups A, B, and C were transplanted with the same volume of ApoJ-transfected BMSC suspension, BMSC suspension and normal saline, respectively.At 1, 3, 5 and 7 days after transplantation, the neurofunction recovery of the rats were evaluated with modified Neurological Severity Scores (mNSS), the brain water content measured by the dry -wet weight method, and the expression level of complement component 3 (C3) in the brain tissue detected by Western blot . Results The mNSS exhibited no statistically significant differences among the three group of rats on the 1st day after transplantation (P>0.05), but was remarkably lower in group A than in B and C on the 3rd (8.13±0.99 vs 9.25±1.28 and 10.88±0.84, P<0.05), 5th (6.75±1.04 vs 8.50±1.41 and 9.75±0.89, P<0.05) and 7th day (5.63±0.52 vs 7.00±0.54 and 7.88±1.25, P<0.05), and markedly lower in group B than in C (P<0.05).The water content in the brain tissue was also significantly lower in group A than in B and C on the 1st (78.17±0.82 vs 78.83±0.56 and 80.38±0.35, P<0.05), 3rd (78.68±0.55 vs 79.12±0.26 and 81.47±0.26, P<0.05), 5th (77.00±0.58 vs 78.13±0.46 and 79.74± 0.41, P<0.05) and 7th day (75.89±0.46 vs 76.86±0.29 and 78.44±0.44, P<0.05), and remarkably lower in group B than in C (P<0.05).Western blot showed that the expression of the C 3 protein in the brain tissue was markedly decreased in group A as compared with B and C on the 1st (0.096±0.011 vs 0.212±0.014 and 0.440±0.006, P<0.05), 3rd (0.083±0.005 vs 0.164±0.013 and 0.604± 0.011, P<0.05), 5th (0.064±0.009 vs 0.105±0.010 and 0.333±0.010, P<0.05), 7th day (0.045±0.007 vs 0.091±0.004 and 0.141± 0.003, P<0.05), and significantly lower in group B than in C (P<0.05). Conclusion ApoJ can promote the recovery of the neuro-logical function of ICH rats by inhibiting complement activation -mediated secondary brain damage and alleviating cerebral edema .
