Objective To study 3D construction and printing of bone tissue engineering scaffolds by bone defect modeling on Mimics software based on CT data. Methods CT data of jaw bone defect from patients were acquired and the images were segmented using threshold segmentation combined with region growing . The three dimensional model was reconstructed by Boolean operation. The individual 3D digital model was reconstructed with internal structure by combining with computer; preparing poly-lactic acid scaffold in virtue of 3D technology. Results Using the Mimics software, we successfully constructed a 3D digital reconstruction model of bone defect based on CT data. The constructed scaffold model with certain internal form and structure was matched with the bone defect of patients, and the constructed model was exported onto STL standard format, which may be in common use. Conclusion The 3D digital model of bone defect scaffolds may effectively be reconstructed based on the CT data using Mimics software and computer aided design.

Objective To explore the protective effect of brain-derived neurotrophic factor (BDNF) on cultured rat cortical neurons against glutamate (Glu)-induced injury and its mechanism. Methods Cortical neurons were primarily cultured from 1-day-old newborn Sprague-Dawley rats and then cultured for 7 d. The cortical neurons were divided randomly into 3 groups: control group,Glu group and BDNF group after identified with neuron-specific enolase (NSE) immunostaining. The cells of BDNF were treated with 50 ng/ml BDNF on day 6 for 24 h followed by cultured with 50 ?mol/L Glu for 0.5 h. While,the cells of Glu group were cultured with 50 ?mol/L Glu for 0.5 h on day 7. The control cells received no such treatments. On day 8,cell viability were determined by the colorimetric MTT assay. The morphological features of the neuron cells were observed under AO/EB fluorescence microscopy. Expressions of p75NTR,JNK and ERK were observed using Western blot analysis. Results On day 8,the primary cortical neurons grew well. BDNF protected cortical neural cells from Glu injury. Cell viability of BDNF group was (1.14?0.06),significantly higher than that of Glu group (0.72?0.10,P

In order to simultaneously remove carbon and nitrogen from organic-rich wastewater, we used an up-flow anaerobic sludge bed/blanket (UASB) reactor that was started up with anammox with high concentration of carbon and nitrogen by gradually raising the organic loading of influent. We optimized the removal of nitrogen and carbon when the chemical oxygen demand (COD) concentration varied from 172 to 620 mg/L. During the entire experiment, the ammonium and total nitrogen removal efficiency was higher than 85%, while the average COD removal efficiency was 56.6%. The high concentration of organic matter did not restrain the activity of anammox bacteria. Based on polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) and tapping sequencing analyses, the Planctomycete, Proteobacteria, Chloroflexi, Chlorobi bacteria are detected in the UASB reactor, which indicated complex removal pathway of carbon and nitrogen coexisted in the reactor. However, a part of Planctomycete which referred to anammox bacteria could tolerate a high content of organic carbon, and it provided help for high performance of nitrogen removal in UASB reactor.

Objective To compare the clinical effects and safety of treating newly diagnosed type 2 diabetes patients by combining Glargine insulin with Metformin or/and Acarbose. Methods 84 patients with newly diagnosed type 2 diabetes ,who have a history of weight loss, body mass index( BMI )23 ~ 28kg/m2 and poorly controlled blood glucose in Metformin at least a month ,were randomly divided into three groups. Glargine insulin plus Mefformin were used in group A. Glargine insulin plus Acarbose(without mefformin)were used in group B, Glargine insulin, Acarbos and metformin were used in Group C. All three groups were given a 12-week follow-up. Results FBG,2hBG and HbA1c levels were lower in the patients after treatment( P <0. 05 ). HbA1c of patients was partly up to the standard in group A and group B,but HbA1c of patients was all up to the standard in group C. The effects in group C were better than those in group A and group B. It had the shortest time to achieve the target and the smallest dose of insulin in group C. BMI in group A and B did not change but decreased in group C(P>0.05).The incidence of low blood sugar in all three groups was low and no significant difference observed among three groups (P>0.05). And in all three groups no severe hypoglycemia occurred. Conclusion The method of combining Glargine insulin with Mefformin or/and Acarbose could effectively control blood sugar had little impact on body weight of the newly diagnosed type 2 diabetes patients, and moreover, the incidence of low blood sugar in the newly diagnosed type 2 diabetes patients was lower. It would be the ideal method to treat newly diagnosed type 2 diabetes patients considering the general safety and effectiveness and convenience.

To study the enrichment regulation of anammox bacteria during the whole start-up process of anammox reaction, two reactors with addition of carries of Spherical Plastic (SP) and Bamboo Charcoal (BC) and one without carrier (CK) were used to start anammox reaction. Then FISH and q-PCR analyses for the growth of all anammox bacteria were conducted during the operational process. The results indicate that the number of anammox bacteria in all reactors increased with time during the whole start-up process, which was consistent with the removal rate of ammonium and nitrite. On day 123 of stable phase, the percent of anammox cells in the sludge of CK, SP and BC accounted for 23.3%, 32.6% and 43.7%, respectively. The number of anammox bacteria 16S rRNA gene copies was (25.64 +/- 2.76) x 10(7), (47.12 +/- 2.76) x 10(7) and (577.99 +/- 27.25) x 10(7) copies g(-1) VSS in the sludge of CK, SP and BC, respectively. Carrier addition could dramatically increase enrichment of anammox bacteria. BC addition significantly increased the anammox bacteria number in the UASB reactor which resulted in the acceleration of the anammox start-up process. In addition, the max specific growth rate and the minimum doubling time were 0.064 d(-1) and 10.8 d in BC reactor. The max specific growth rate of anammox bacteria in BC reactor was 1.78 times and 1.88 times greater than that in CK and SP reactor, respectively. Therefore, the FISH and q-PCR analyses were suitable for determining the enrichment regulation of anammox bacteria during the start-up time, while a bit of differences in results existed between the two analytical methods due to the difference in analysis targets.

Immunogenicity for medical devices of animal origin is the key and difficult point during immune safety evaluation for these devices. This paper firstly investigated the effect of collagen sponge of animal origin on mouse splenic lymphocyte transformation and proliferation, and then analyzed the influence factors on the MTT method and CFSE method. The results showed that collagen sponge extract cannot significantly induce transformation and proliferation of mouse splenic lymphocyte in vitro.
