OBJECTIVETo compare the shear bond strength(SBS) of cast Co-Cr alloys and selective laser melting(SLM) Co-Cr alloys with those of dental porcelain.

METHODSA dental porcelain (Vita) was applied on cast and SLM Co-Cr alloy specimens (n = 10). SBS test was conducted, and fracture mode analysis was determined. Student's t-test by SPSS 13.0 software was employed to analyze the data.

RESULTSThe SLM Co-Cr alloy specimens had lower SBS values than the cast Co-Cr alloy specimens (P > 0.05). The metal-porcelain bond strength value of the cast group was (33.11 +/- 4.98) MPa, and that of the SLM group was (30.94 +/- 5.98) MPa. The specimens in both test groups exhibited mixed failure.

CONCLUSIONThe metal-porcelain system processed by SLM exhibit a bond strength that is similar to that of the cast group. This system also display a high precision.

We have constructed an immunotoxin(Ng76-TCS),which was composed of a monoclonalantibody directed against human melanoma and trichosanthin(TCS)——a single chain ribosomeinactivating protein.The cultured human melanoma cells(M21)were inhibited effectively byNg 76-TCS.The cytotoxicity of Ng76-TCS to M21 cells was 2,000-fold higher than that of free TCS and Ng76 mixture.A conjugate,which was prepared with normal mice immunoglobulinand TCS(NIgG-TCS),was 160-fold less cytotoxic to M21 cells.Meanwhile Ng76-TCS was125-fold less cytotoxic to nontarget cells Hela.These results showed that the immunotoxinNg76-TCS was a potent and specific anti-human melanoma agent.

In this paper, three kinds of chemotactic parameters (concentration, temperature and pH) were determined by plate assay and spore germination method to research the chemotactic response of Botrytis cinerea and Alternaria panax, and their spores on total ginsenosides. The results showed that Botrytis cinerea had strong chemotactic response at the mid-concentration of total ginsenosides (cultivation temperature was 20 degrees C and pH value was 6), and the data of chemotactic migration index (CMI) was 1.293 0, chemotactic growth rate (CGR) was 0.476 0, spore germination rate (SGR) was 53%, and dry weight of mycelial (DWM) was 0.452 6 g x L(-1); however, Alternaria panax had strong chemotactic response at the low-concentration of total ginsenosides (cultivation temperature was 25 degrees C and pH value was 6), and the data of chemotactic migration index (CMI) was 1.235 4, chemotactic growth rate (CGR) was 0.537 0, spore germination rate (SGR) was 67%, and dry weight of mycelial (DWM) was 0.494 8 g x L(-1). The results indicated that the low and middle concentration (2, 20 mg x L(-1)) of total ginsenosides had significant promoting effect on chemotactic response of these two pathogens, and the spore germination, mycelial growth rate, dry weight of mycelial of them were also significantly improved by this chemotactic response, whereas it decreased as the increase of total ginsenosides concentration.

The lipase labeled with the fluorescein isothiocyanat (FITC) was immobilized on the derivatives of the polyethylene glycol. The article discussed the effect of factors on the characters of lipase and analyzed the relationships among the activity of lipase, conformation, and fluorescence spectrum while the activity and the fluorescence spectrum of immobilized lipase were determined. The results demonstrated that polyethylene glycol 400-diacrylate could form appropriate network to improve the activity of enzyme. Adding ligand induced the lipase's catalytic conformation to increase the activity twice more than before. The active centre of lipase could be released by the extraction of ligand thus increasing the activity. After immobilization, the stability of labeled lipase improved greatly: immobilized lipases retained more than 70% and 60% of initial activity under conditions of 90 degrees C and strong acid or alkali, respectively. After immersing immobilized lipases into guanidine hydrochloride or urea for 15 days, the lipases retained upwards of 70% activity. The fluorescence spectrum could obviously reflect the changes of the activity and conformation of lipase. The fluorescence intensity was the minimum in the optimal pH and temperature. In the denaturing agent it declined as time passed. These results indicated that the unfolded processes of immobilized lipases are different under different conditions.

BACKGROUND: The present study aimed to explore the relationship between surgical methods, hemorrhage position, hemorrhage volume, surgical timing and treatment outcome of hypertensive intracerebral hemorrhage (HICH). METHODS: A total of 1310 patients, who had been admitted to six hospitals from January 2004 to January 2008, were divided into six groups according to different surgical methods: craniotomy through bone flap (group A), craniotomy through a small bone window (group B), stereotactic drilling drainage (group C1 and group C2), neuron-endoscopy operation (group D) and external ventricular drainage (group E) in consideration of hemorrhage position, hemorrhage volume and clinical practice. A retrospective analysis was made of surgical timing and curative effect of the surgical methods. RESULTS: The effectiveness rate of the methods was 74.12％ for 1310 patients after one-month follow-up. In this series, the disability rate was 44.82％ 3–6 months after the operation. Among the 1310 patients, 241 (18.40％) patients died after the operation. If hematoma volume was >80 mL and the operation was performed within 3 hours, the mortality rate of group A was significantly lower than that of groups B, C, D, and E (P<0.05). If hematoma volume was 50–80 mL and the operation was performed within 6–12 hours, the mortality rate of groups B and D was lower than that of groups A, C and E (P<0.05). If hematoma volume was 20–50 mL and the operation was performed within 6–24 hours, the mortality rate of group C was lower than that of groups A, B and D (P<0.05). CONCLUSIONS: Craniotomy through a bone flap is suitable for patients with a large hematoma and hernia of the brain. Stereotactic drilling drainage is suggested for patients with hematoma volume less than 80 mL. The curative effect of HICH individualized treatment would be improved via the suitable selection of operation time and surgical method according to the position and volume of hemorrhage.

To investigate the relationship between serum retinol-binding protein 4(RBP4) and gestational diabetes mellitus (GDM) in Chinese Han pregnant women.195 (23-42 years) pregnant women were recruited (July 2005 to December 2007) from the Department of Gynecology and Obstetric in Ruijin Hospital during their visiting for routine prenatal examination.99 subjects belonged to GDM group,and 96 belonged to the group with normal glucose tolerance (NGT).65 non-pregnant healthy women served as control.Serum RBP4 was measured using sandwich enzyme linked immunosorbent assay (ELISA).Pregnant women had higher level of serum RBP4 than that of non-pregnant control.The concentration of serum RBP4 was significantly increased in GDM group as compared with NGT group[(43.04±1.85 vs 33.84±2.17) rag/L,P<0.01].Multiple stepwise regression analysis showed that triglycerides and homeostasis assessment for insulin resistance (HOMA-IR) were independent variables of RBP4 (r2 =0.165) in pregnant women.The results suggest that serum RBP4 level is significantly increased in pregnant women.Women with GDM had even higher RBP4 level than that of normal pregnant women,and RBP4 levele was positively correlated with triglycerides and HOMA-IR.

Objective To compare the subjective satisfaction of the free radial forearm flap (FRFF) and anterolateral thigh flap (ALTF) of the donor site after surgical reconstruction for tongue cancer. Methods A total of 121 consecutive patients underwent FRFF or ALTF reconstruction after ablative surgery for untreated, primary tongue squamous cell carcinoma at Tianjin Stomatological Hospital and Peking University School and Hospital of Stomatology from August 2011 to October 2014 were enrolled in this study. The subjective satisfaction of the donor site, including sensibility, movement disabilities, cosmetics, social activities and general impacts on the quality of life (QOL), was assessed by a self-established donor site morbidity questionnaire from October 2016 to January 2017. Results Of the 121 patients, 34 died because of cancer or other diseases, 2 were excluded because of recurrence after reconstruction surgery, 11 lost to contact, and 74 (61.2％) completed the questionnaires finally, which included 39 patients in FRFF group and 35 patients in ALTF group. The scores for sensibility, cosmetics, general impacts on the QOL and composite score were significantly higher in ALTF group than those of FRFF group (P<0.05). No significant differences were found in the movement disabilities and social activities between the two groups (P > 0.05). Conclusion ALTF has the advantage of better results of donor site morbidity, less adverse effect on the general QOL, and higher subjective satisfaction.
