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.

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 study the therapeutic effect of pinaverium bromid and oryz-aspergillus enzyme and pancreatin tablet on patients with bile duct Ⅲ of sphincter of Oddi dysfunction (SOD) after cholecystectomy.Methods 72 patients who had a diagnosis consistent with bile duct Ⅲ of SOD seen from February 2010 to February 2013 in our hospital were randomly divided into the control group and the treatment group.Patients in the control group were given pinaverium bromid for 3 months while patients in the treatment group were,in addition to pinaverium bromid,given oryz-aspergillus enzyme and pancreatin tablet.Relief of abdominal pain,abdominal distention and recurrence of the above symptoms after drug withdrawal were studied.Results The scores on abdominal pain in the treatment group before and after treatment were 7.5 ± 1.1 and 3.0 ± 1.6 (P ＜ 0.05) while the scores in the control group were 7.4 ± 1.1 and 5.0 ± 1.4 (P ＜ 0.05),respectively.Alleviation of abdominal pain in the treatment group was superior to the control group (P ＜ 0.05).The scores on abdominal distention in the treatment group before and after treatment were 5.4 ± 0.6 and 1.6 ± 0.5 (P ＜ 0.05) while the scores in the control group were 5.2 ± 0.5 and 4.7 ± 0.8 (P ＞ 0.05),respectively.Alleviation of abdominal distention in the treatment group was superior to the control group (P ＜0.05).The scores of abdominal pain and distention in half year after 3 months' therapy in the treatment group were 3.1 ± 1.7 and 1.7 ± 1.1,respectively,which obviously were lower than the control group (5.4 ± 1.4 and 5.0 ± 0.6,P ＜ 0.05).Conclusions Pinaverium bromid and oryz-aspergillus enzyme and pancreatin tablet could effectively alleviate abdominal pain and distention in patients with bile duct Ⅲ of SOD after cholecystectomy and the recurrence rates of symptoms were significantly lower.

Alzheimer’ s disease ( AD) is one of the most common dementia of neurodegenerative disorders, which results from the deposition of amyloid-beta ( Aβ) and there are no curative treatments for this disease at present.It had been proved that prion protein is the receptor for Aβand it plays a key role in the progress of AD with dual-side effects. Prion protein can not only transfer neurotoxicity to neurons but also protect them from neurotoxicity of Aβ.The polymor-phisms of prion protein encoding gene ( PRNP) affect the AD incubation period and clinical symptoms in humans and other animals.The discovery of PRNP mutational mouse fills the gaps of existing AD mouse models in this research area, which is potential for the studies of pathogenesis, new drugs design and testing aspects.The role and effects of prion protein in AD pathogenesis were summarized in this paper, furthermore, the discovery and utility of PRNP gene mutational mouse in research on AD and/or amyloid diseases were reviewed, and in order to provide some guidance for AD animal model study.
