BACKGROUND:Raloxifene is the third generation of selective estrogen receptor modulators, which can decrease bone loss, increase bone mineral content, and reduce fracture risk. OBJECTIVE: To study the effects of raloxifene combined with self-setting calcium phosphate cement on the repair of rabbit mandibular defects. METHODS:Totaly 36 New Zealand white rabbits were selected to prepare 8 mm×4 mm×3 mm mandibular defect models, and then randomized equaly into experimental group (raloxifene, 7.5 mg/kg per day, combined with self-setting calcium phosphate cement), drug group (raloxifene, 7.5 mg/kg per day), artificial bone group (self-setting calcium phosphate cement). Rabbits were sacrificed 4, 8 and 12 weeks later, respectively, for measurement of bone morphogenetic protein 2 using immunohistochemistry method and transforming growth factor β using a laser scanning confocal microscope. RESULTS AND CONCLUSION:After 4 and 8 weeks, the expression of bone morphogenetic protein 2 was obviously higher in the experimental group than the drug and artificial bone groups; after 12 weeks, bone remodeling was basicaly complete in the experimental group, and the expression of bone morphogenetic protein 2 became lower than that in the other two groups. The expression of transforming growth factor β in the experimental group was gradualy increased and reached the peak at 8 weeks, while in the drug and artificial bone groups, the expression of transforming growth factor β exhibited an increasing trend within 4-12 weeks, which was close to the peak. These findings suggest that raloxifene can promote early expression of bone morphogenetic proteins and early calus formation as wel as accelerate the repair of bone defects with calcium phosphate cement.

0.05).Conclusion The propofol TCI system can be safely used in surgical operation for patients with lymphedema.

Objective To investigate analgesic effects of flurbiprofen in lower extremity liposuction for patients with primary lymphedema. Methods A total of 60 patients receiving lower extremity liposuction under general anesthesia were allocated to 3 groups:the control group (group A) received no analgesic drug 10-20 min before the end of operation, the parecoxib group (group B) received intravenous parecoxib 40 mg, and the flurbiprofen group (group C) received intravenous flurbiprofen 100 mg.The VAS was recorded at 1, 2, 6, 12, and 24 h after operation.Adverse reactions were also recorded . Results The VAS of rest pain and motion pain at 1, 2, 6, and 12 h were significantly lower in the group B than those in the group A (P<0.05);the VAS of rest pain and motion pain at 1, 2, and 12 h were significantly lower in the group C than those in the group A (P<0.05).The VAS at 1 and 2 h did not differ between the group B and C (P>0.05), but had significant difference at 6 and 12 h (P<0.05).No significant differences in the VAS at 24 h were observed among the three groups (P>0.05).Adverse reactions were not different among the three groups (P>0.05). Conclusion Both flurbiprofen and parecoxib sodium can achieve good postoperative analgesic effects in patients with lymphedema receiving lower extremity liposuction .

Objective To map out the binding site of P195,which is the major protein on the surface of P.falciparum merozoites,to human erythrocytes,and offer a basis for designing malaria vaccine to blockade invasion of merozoites into human erythrocytes.Methods Eight proteins derived from P195 were expressed in E.coli,and purified by Ni-chelare affinity chromatography.There after,the eight fragments and rabbit serums immunized by which were added into culture medium of P.fatciparum in vitro respectively.Twenty-four hours later,the invasion of merozoite to erythrocyte was observed.Results The antibodies which were induced by three fragments of P195,M6(Amino Acid,AA384～595),M7(AA 595～897)and M11(AA 1397～1563)could inhibit the invasion of P.falciparum merozoite into human erythrocytes.Especially,one fragment of P195,M6,had the ability to inhibit the invasion of P.falciparum merozoite into human erythrocytes.Conclusion M6,a fragment of P195 on the merozoite of P.falciparum may contain a domain thought to be involved in the recognition of human erythrocyte.The domain can be used as a candidate antigen for a malaria vaccine.

The proteomics definition, investigation method and its a pplication in cancer research were simply introduced. Proteomic research is to r eveal the function of genes from an integrated, kinetic and quantitative view at the global protein level, which is an important component of post-genome proje ct. Cancer is a kind of complex disease involved by multi-genes. Proteomic rese arch will be helpful to discover the mechanism of cancer development, to find sp ecial malignant tumor markers and targets of drug treatment.

To compare the varieties and contents of the main nerval information molecules in perfusate from hypothalamic medial preoptic area (MPOA) of the rats in different sexual cycles and the ovariectomized rats treated by electro-acupuncture, so as to observe the similarities and differences of hypothalamic neuroendocrine signal transduction pathway under the physiological and pathological status, and to explore the mechanisms of neuroendocrine signal transduction of electro-acupuncture therapeutic effect in perimenopausal syndrome.

Objective To present the management of increasing the closure stress of urethra for treatment of stress urinary incontinence in women. Methods In 12 patients with stress incontinence the posterior urethra and the anterior wall of the bladder was incised.Then the wall of posterior urethra,bladder neck and bladder trigone were trimmed and sutured to form a tube whereby to elongate and tighten the posterior urethra referring to Campbell-Young's way and according to Laplace's law. Results The mean period of post-operative follow-up was 8.8 years.Eleven patients could completely control their urinating without residual urine after the operation.The short-term and long-term outcomes were the same in these 11 patients.For the remaining one patient little urine was spilt when the abdominal pressure was increased with exertion. Conclusions Elongating and tightening the posterior urethra is simple,effective and safe for treatment of stress urinary incontinence in women.
