The transplants of one-year-old Glycyrrhiza uralensis Fisch. were subjected to five concentrations of MnSO4-H2O (0, 1.81, 18.1, 36.2 and 54.3 mg·L(-1)) culturing in vermiculite. qRT-PCR and HPLC were respectively used to measure the relative expression of SQS1 gene and the content of glycyrrhizic acid of G. uralensis in different concentrations of MnSO4·H2O. This is to explore discuss the effects of the expression of SQS1 gene and the accumulation of glycyrrhizic acid by Mn treatment. The results showed both the expression of SQS1 gene and the content of glycyrrhzic acid of G. uralensis tended to rise after the fall of the first with the increase of concentration of Mn treatment. And they were of very significant positive correlation (P<0.01, r=0.737). Relative expression of SQS1 gene reached the highest 7.90 under 18.1 mg·L(-1) MnSO4·H2O treatment. It was very significantly different between 18.1 mg·L(-1) concentration of MnSO4·H2O treatment and CK (0 mg·L(-1)), 1.81, 36.2 and 54.3 mg·L(-1) (P<0.01), and 1.75, 1.37, 1.37, 2.33 times respectively. The content of glycyrrhizic acid reached the highest under 1.81 and 18.1 mg·L(-1) MnSO4·H2O treatment, and there were not significant difference (P>0.05). It was very significantly different between them and other concentrations of MnSO4·H2O treatment (P<0.01). This study suggests the appropriate concentration of Mn treatment could certain promote the expression of SQS1 gene and the accumulation of glycyrrhizic acid of G. uralensis.

This paper developed a calculation method to acquire the yield load P of bone plate during four-point bending test. This method is based on the displacement--force (δ-F) curve function f(M)(δ) obtained from the test, each slope of the curve was calculated using piecewise smooth function and the line segment in f(M)(δ) elastic deformation area was searched by setting the minimum slope T. Slope S was obtained through linear fit so as to build parallel displacement function f(L)(δ). Then, approximating intersection point of f(M)(δ) and f(L)(δ) was obtained through linear interpolation. Thus, yield load P was acquired. The method in the paper was loyal to YY/T 0342-2002 regulation and was liable to program calculation. The calculating process was nothing to do with whether the initial point during the test was preloaded or unloaded, and there was no need to correct the original point. In addition, T was set in an ideal fitting level guaranteed by the fitting coefficient of determination R2, and thus S was very close to the real value, and P was with a high accuracy.

Livin is a new and important member of the inhibitor of apoptosis protein(IAPs)family.Livin is high expressed in most human tumor cells, involved in apoptosis inhibition and closely related with tumor development and progression.Studies found that through the down-regulation or inhibition of Livin expression and the induction specific antibodies of Livin could inhibi and kill tumor cells, which provided a new method for tumors'diagnosis, cell and gene targeted therapy.

Object iv e To observe the intermediate-term results of the H /G total hip arthroplast y.Methods Thirty-fivecases(40hips)with the H /G THA were reviewed with an average of 7.5years fol-low-up(range,6to10.2years).In th is grou p,the primary lesions of hip included avascular necrosis of femoral head(1 2hips,10cases),congenital dysplasia of hip(9hips,8cases),femoral ne ck fracture(8hips,8cases),osteoarthritis(4hips,4cases),reversion(3 hips,3cases)and ankylosing spondylitis(4hips,2cas-es).The clinical res ults were scored with Harris methods.The roentgenographic results were analyzed with Am stutz meth ods.Results Theclinical average Harris scores were95in3-year follow-up,89in5-year fol-low-up,83in7.5-year follow-up. Roentgenographic results of femoral components showed20hips with in-tra medu llary ossification,18hips with cortical hypertrophy around the distal prosthe ses,25hips with lo cal re-di olucent line,10hips with osteolysis in femu r calar and2hips with implants subsiding less than7mm.Roentgenographic resul ts of acetabular component revealed20hips with radi olucent line(8compo n ents with around radiolu cent,12components with local radiolucent ),7hips with osteolysis and1hip with polyethylene lining defluxion.Conclusion Theresul ts of clinical and roentgenographic performance in mid-dle-term is not as go od as that in short-term.The abnormal bone reaction is evidently higher in mid dle-term than in short-term.Though the above-mentioned manifestation is only restricted on the roentgenogram with-out clinic symptom,however,further fol low-up is need ed.It should be noted that one case had revi sion be-cause of the polyethylene lining defluxion resulted from clip loosening on the metal ace tabular com po nent ;although this seldom happens both at home and abroad,more attention should be paid to the revi sion case re-sulted from the mechanical m alfunction not from the prosthesis loosening.

AIM To investigate actions of total paeony glycoside(TPG) on learning and memory capacity and related products of metabolism of senile mice induced by D galactose. METHODS The subacute senile mouse models induced by injection of D galactose subcutaneously were used. RESULTS TPG could improve the learning and memory capacity of model mice in shuttle test and enhance spatial resolution in water maze test. TPG not only reduced the content of monoamine oxidase(MAO) and inhibited the decrease of cholinesterase(CHE) significantly, but also lessened the level of malondialdehyde(MDA) and inhibited the decrease of superoxide dismutase(SOD) in cerebrum of model mice. TPG still promoted the recovery of lobar atrophy and hypoimmunity of senile mice remarkedly. CONCLUSION TPG possesses obvious effects of improvement on learning, spatial resolution and delaying senility.
