[Objective]To observe the effect and the safety of the COX-2 inhibitor Celecoxib as the analgesia in orthopaedic post-operative patients.[Method]Sixty-four operative patients were selected in all between 2004～2005 in hospital,and divided into two groups randomly.Celecoxib was used as the postoperative analgesia in the experiment group and the "Patient-controlled analgesia" in the control group.The administration of Celecoxib: 8-12 hours before operation generally,just before the abrosia,and 6 hours after operation when patients can take food.drug withdrawal was depended on the complex of the operation and the severety of pain in 3 to 5 days.Dosage:400 mg first time,if a complicated operation,larger dose would be given.VAS score,adverse reaction and the satisfaction of patients were observed.[Result]The effect of Celecoxib is similar as the PCA,with less adverse reaction and more satisfaction.[Conclusion]Celecoxib has a satisfactory effect and safety as a postoperative analgesia,and is suitable to be a peri-operative analgesia of orthopaedic patients.

[Objective]To provide a precise individualized design proposal for locating acetabular prosthesis by means of 3D reconstruction,reverse engineering software and rapid prototyping technology.[Method]3D CT scan pelvis image data were obtained from six patients,which displayed osteonecrosis of femoral head on one side.The data were transferred via a DICOM network into a computer workstation.A 3D model of hip was reconstructed using Amira 3.1 software,and saved in STL format.Then the 3D model was imported into Imageware 12.0 software.The normal hip joint centre of abnormal side was determined and the best orientation of the prosthesis(which was central axial ray of acetabula)was defined using reverse engineering.Locating template was designed according to the anatomic features of the acetabula and the central axial ray.Entity model was produced by rapid prototyping technology.The orientation of the prosthesis was located by matching the model to acetabular concavity at operation.[Result]By measuring postoperative standard hip anteroposterior film,the abduction angle of acetabular prosthesis was(46.00?2.49)? and the anteversion angle was(15.68?2.85)?.The expected result was obtained.[Conclusion]The navigation template designed and constructed preoperatively can provide precise location for acetabular prosthesis and avoid procedural errors at operation.

Wnt/β-catenin signaling pathway plays an important role in the proliferation, growth, invasion, and metastasis of human cancers. Moreover, β-catenin/T-cell factor 4 (TCF4) interaction regulates the transcription of the key oncogenes in Wnt/β-catenin signaling pathway. Therefore, β-catenin/TCF4 interaction would be a promising therapeutic target for the development of highly selective anticancer agents. At present, most ongoing small-molecule inhibitors targeting β-catenin/TCF4 interaction, including PKF222-815, iCRT3/5/14, LF3, and sanguinarine, have been developed in preclinical studies for human cancer therapeutics. In this review, we summarized the research advances of up-to date inhibitors targeting β-catenin/TCF4 interaction, including the molecular structure and cellular functions of β-catenin in canonical Wnt signaling pathway. This review holds a hopeful avenue for the development of novel and highly selective Wnt inhibitors targeting β-catenin/TCF4 interaction for future anticancer strategy.

Objective To explore the effect of group psychological training on the mental health and self consistency of nurses from operating rooms.Methods 52 nurses of an operating room were randomized into the treatment group(n=25)and the control group(n=27): The latter received humane care and instructions for mental self care and the former received group psychological training for 8 weeks based on the same treatment as in the control group.Symptom checklist 90(SCL-90)and self consistency and congruence scale(SCCS)were used to assess and compare the difference of the two groups before and after training.Results The intra-and inter-group comparisons between pre-and post-intervention showed statistical differences in terms of the total score by SCL,interpersonal sensitivity,depression and hostility,total score by SCCS and the score on the subscale of inconsistency between themselves and their experience(all P<0.05 or P<0.01).Conclusion Group psychological training can effectively improve the level of mental health and self consistency of OR nurses and thus can improve the total psychological status of the OR nurses.

BACKGROUND:Genetic studies have shown that there may be association between osteoprotegerin gene G1181C polymorphism and bone mineral density in postmenopausal women, but there are some differences in the conclusions.
OBJECTIVE:To study the association between osteoprotegerin gene G1181C polymorphism and bone mineral density in postmenopausal women through Meta-analysis.
METHODS:The PubMed database, Embase database, CNKI database and Wanfang database were searched for the observational studies about the association between osteoprotegerin gene G1181C polymorphism and bone mineral density in postmenopausal women. The standardized mean difference was considered as the effect indicator and calculated with random or fixed effect models according to the significance of heterogeneity.
RESULTS AND CONCLUSION:A total of 9 articles were included with a total of 8 799 and 9 365 participants for which vertebral and spine bone mineral density had been measured, respectively. The analysis results showed that the bone mineral density of the postmenopausal women with the G al ele of G1181C was significantly lower than that of the postmenopausal women with the C al ele. Similar results were obtained in Caucasian population subgroup analysis. The Caucasian population subgroup analysis showed that the bone mineral density of the postmenopausal women with GG genotype of G1181C was lower than that of the postmenopausal women with GC and CC genotype. The results indicate that there is association between osteoprotegerin gene G1181C polymorphism and bone mineral density in postmenopausal women, and G al ele is a risk factor for lower bone mineral density.

OBJECTIVE: To observe the effects of Spleen- strengthening decoction on GLP- 1 in patients with type II diabetes. METHODS: A randomized double- blind placebo- controlled test was conducted, and through observations for 8 wks, the changes of the two patient groups in plasma glucose, HbA1c, plasma GLP- 1 and Glucagon as well as TCM symptom score were measured for comparison. RESULTS: Before administration of Spleen- strengthening decoction, the two groups showed no significant difference in all of the indexes. After administration, the treatment group recorded lower indexes in fasting plasma glucose, HbA1c and plasma Glucagon, but higher index in fasting plasma GLP- 1, with no significant difference seen in other indexes. CONCLUSIONS: Spleen- strengthening decoction can improve glucose metabolism through heightening fasting plasma GLP- 1, and lowering both Glucagon and fasting plasma glucose.

ObjectiveTo study the change of the pulmonary surfactant protein C, D (SP-C, SP-D) and apoptosis of alveolar epithelium cells in neonatal rats with hyperoxia-induced lung injury.MethodsThe neonatal rats born within 24 hours were divided into the air group (n=50) and the hyperoxia group (n=50). The lung tissue was collected on the ifrst, third, seventh, tenth, fourteenth day after the hyperoxia exposure. The pathological changes were observed by HE staining. The apoptosis rate of lung epithelial cells was detected by TUNEL (terminal deoxyn ucleotidyl transfer-mediated end labeling). The content of SP-C and SP-D in broncho alveolar lavage lfuid (BALF) was detected by enzyme-linked immunosorbent assay.ResultsIn the air group, as age increased, the alveolar were gradually more completely formed with the regular shape and uniform size. Mean-while, in the hyperoxia group, as age increased, the number of alveolar was reduced, the small blood vessels expanded, the alve-olar hemorrhage was increased, the interstitial cells were increased and the lung tissue was swelling. The levels of SP-C, SP-D decreased with the increase of age in the air group. The level of SP-C in hyperoxia group was lower than that in the air group on the ifrst day. It was higher than that in the air group on the third day, peaked on the seventh day, and then it began to decline on the tenth day and decreased more obviously on the fourteenth day. The level of SP-D in hyperoxia group was not signiifcantly dif-ferent from that in the air group on the ifrst day, was higher than that in the air group on the third day and peaked on the seventh day. Then it began to decline on the tenth day and decreased more on the fourteenth day. ConclusionsLong-term inhalation of high concentrations of oxygen inhibits alveolar development. With the prolonged time of oxygen inhalation, the apoptosis of lung epithelial cells is increased, and the level of SP-C and SP-D in BALF was increased ifrst and then decreased.
