Full ceramic prosthesis is becoming the main prosthetic development direction. As an important kind of full ceramic prosthesis, full ceramic veneer has not only natural cosmetic appearance and perfect biocompatibility, but also can preserve tooth structure as much as possible, which would be more easily accepted by patients for cosmetic prosthesis. Many methods, such as slip casting, die casting and CAD/CAM technology are available to make full ceramic veneer. All the methods have their own advantages and disadvantages. Slip casting is easy to be developed widely with low cost, so be used in practical work. In this article, the working process of full ceramic veneer, especially manufacture of removable dies, duplication of refractory models, were introduced, which was supposed to be beneficial for the technicians.

BACKGROUND:Lumbar spinal stenosis is clinical repaired with decompression, bone fusion and internal fixation, and different internal fixation materials can be chosen during the surgery. OBJECTIVE:To explore the influence of polyetheretherketone (PEEK) pedicle screw fixation combined with interbody fusion on the bone fusion rate of patients with lumbar spinal stenosis. METHODS:A retrospective analysis was performed in 63 cases of lumbar spinal stenosis undergoing decompression and interbody fusion. These patients were divided into control group (titanium internal fixation system,n=31) and experimental group (PEEK pedicle internal fixation system,n=32) according the internal fixation materials folowed by posterior spinal decompression with interbody fusion. The Oswestry dysfunction index scores before and 4, 12, 24 weeks postoperatively and bone fusion rates at 4, 12, 24 weeks postoperatively were compared between the two groups. RESULTS AND CONCLUSION:Oswestry dysfunction index scores showed a gradual decline in both two groups before and 4, 12 and 24 weeks after treatment, but there was no difference at different time (P > 0.05). At 4 and 24 weeks after treatment, there was no difference in the bone fusion rates between the two groups (P > 0.05), but at 12 weeks after treatment, the bone fusion rate in the experimental group was better than that in the control group (P < 0.05). During the surgery, no infection and other adverse events occurred in the two groups. These results indicate that both PEEK and titanium internal fixation systems for lumbar tube stenosis have obtained good results, but PEEK material has a better role in the bone fusion at 4-12 weeks after internal fixation.

In this paper, the action of suet oil in the preparation of self-assembled micelles of the active flavonoids in Epimedium in the simulated human environment was researched. Twelve suet oil samples were collected from different growing areas and different positions of sheep or goat to simulate the formation of micelles. Then the effects of the fatty acids in suet oil on the preparation of self-assembled micelles were studied furthermore. The results showed that the micelles had a dispersed state and spherical smooth surface. To compare the diameter, potential, encapsulation efficiency and drug loading of the 12 batches micelles, the micelles prepared by the suet oil from Qinghai were more stable and had a higher encapsulation efficiency. The fatty acids in suet oil could promote the formation of self-assembled micelles, but the whole suet oil had a better effect. Above all the study, we confirmed that the suet oil promoted the formation of self-assembled micelles of the flavonoids in Epimedium, it laid foundation for further research about increasing the efficacy of Epimedium and improved the absorption of the active flavonoids in Epimedium.

Objective To assess the relationship of serum prealbumin level with the severity of acute ischemic stroke (AIS).Methods The clinical data of 2522 AIS patients who were admitted in Peking Union Medical College Hospital from 2000 to 2008 were retrospectively analyzed.The serum prealbumin and hypersensitive C-reactive protein (hs-CRP) levels were evaluated by immunoturbidimetric assay within 24 hours after admission.The AIS severity was evaluated at admission using modified Rankin Scale (mRS).Patients were divided into mild AIS group (mRS score ≤ 3 ) and severe AIS group (mRS score > 3 ).The levels of serum prealbumin and hs-CRP were compared between these two groups,and the relationship between praalbumin and hs-CRP was also analyzed.Results There were 1697 patients in the mild group (average mRS score:1.67) and 825 patients in the severe group ( average mRS score:4.53 ).The severe group had significantly lower prealbumin level [ ( 191.20,82.00)versus (219.18,72.00) mg/L,P =0.000] and higher hs-CRP level [ (6.01,8.22) versus (4.15,6.93) mg/L,P =0.000 ] than the mild group,respectively.Partial regression analysis showed that the stroke severity was negatively correlated with serum prealbumin level (r =-0.115,P =0.000) and positively correlated with hs-CRP level (r =0.098,P =0.000).Serum prealbumin level was inversely correlated with hs-CRP level ( r =- 0.396,P =0.000).Conclusion The prealbumin level is relevant with the severity of AIS and inflammation.

OBJECTIVETo break through the restrictions of the evaluation model and the quantity of compounds by using the two-dimensional zebrafish model combined with chromatographic techniques, and establish a new method for the high-throughput screening of active anti-osteoporosis components.
METHODAccording to the research group-related studies and relevant foreign literatures, on the basis of the fact that the zebrafish osteoporosis model could efficiently evaluate the activity, the zebrafish metabolism model could efficiently enrich metabolites and the chromatographic techniques could efficiently separate and analyze components of traditional Chinese medicines, we proposed that the inherent combination of the three methods is expected to efficiently decode in vivo and in vitro efficacious anti-osteoporosis materials of traditional Chinese medicines.
RESULT AND CONCLUSIONThe method makes it simple and efficient in the enrichment, separation and analysis on components of traditional Chinese medicines, particularly micro-components and metabolites and the screening anti-osteoporosis activity, fully reflects that efficacious materials of traditional Chinese medicines contain original components and metabolites, with characteristic of "multi-components, multi-targets and integral effect", which provides new ideas and methods for the early and rapid discovery of active anti-osteoporosis components of traditional Chinese medicines.

Objective To investigate health status of medical staff and its impacting factors so as to provide useful health guidance. Methods Health examination data from 2 hospitals in Zhejiang province were collected. The medical staff group was classified into 5 subgroups according to the departments; the control group was composed of other mental labors. The health examinations included clinical, laboratory and special testing. SPSS 11.0 software was used for data analysis. Results Compared with the control group, the morbidity rate of the medical staff group was higher, especially in those aged < 50 (χ2 = 6. 651,8. 883, and 7. 446; all P < 0.05 ). All medical staff subgroups showed significant difference in morbidity rate ( χ2 = 39. 099 ,P < 0.05 ). Hyperlipidemia,cervical erosion,and breast hyperplasia were the most common diseases found in medical staff; while the control group developed more breast hyperplasia, hyperlipidemia, and retinal arteriosclerosis. Conclusions Health status of medical staff could not be optimal. Effective health education would be needed to improve life style and relieve stress.
