BACKGROUND:Machinable bioglass-ceramics became a new inorganic biomaterial; moreover, strength, toughness and machinability are significantly studied.OBJECTIVE: To observe the effect of ZnO, Fe2O3 and ZrO2 additives on the microstructure and properties of machinable bioglass-ceramic in K2O-MgO-CaO-SiO2-P2O5-F system.DESIGN: Observational contrast study.SETTING: Department of Orthopaedics, Tongji Hospital Affiliated to Tongji Medical College, Huazhong University of Science and Technology.MATERIALS: The experiment was carried out in the Laboratory of Materials, Wuhan University of Technology from October 2003 to April 2004. K2O-MgO-CaO-SiO2-P2Os-F system, ZnO, Fe2O3 and ZrO2 additives, D/Max-ⅢA X-ray diffractometer (Japan), JSM-5610LV scanning electron microscope (SEM), HVS-1000 microhardnessmeter and 3257-35 magnetic testing device (Japan) were used in this study.METHODS: In the glass-ceramic of K2O-MgO-CaO-SiO2-P2O5-F system, three kinds of additives ZnO, ZnO-Fe2O3 and ZnO-Fe2O3-ZrO2 were added respectively. These three kinds of ceramics were prepared by being melted at 1 400 ℃ for 1 hour. After fire, crystal temperature was set based on differential thermal analysis curve. ① Physical properties: Microhardness was determined with microhardnessmeter (HVS-1000). The flexural strength and fracture toughness were established measured with ceramic mechanical test system (MTS) method and single edge notched beam (SENB) method, respectively. Saturation magnetic moment and Curie temperature were determined with 3257-35 magnetism test machine made in Japan. Holing method was used to measure machinability. ② Test of crystalline phase and microstructure: Crystalline phase analysis was carried out with X-ray diffraction (XRD: D/Max-ⅢA) and microstructure analysis were conducted on an etched fracture surface using SEM (JSM-5610LV,Japan). MAIN OUTCOME MEASURES: Effects of ZnO, Fe2O3 and ZrO2 additives on physical properties, mineral composition and crystalline phase.RESULTS: ① The addition of ZnO to the glass-ceramic in K2O-MgO-CaO-SiO2-P2O5-F system was beneficial to crystal growth, increasing aspect ratio of crystal, decreasing microhardness and improving toughness and machinability. ② The addition of ZnO-Fe2O3 to the glass-ceramic in K2O-MgO-CaO-SiO2-P2O5-F system can form minority Mg-Zn ferrite with magnetism. The main crystalline phase present in the glass- ceramic was diopside with small size and hardness was improved, which led to worse machinability. ③ Because of the addition of ZnO-Fe2O3-ZrO2, magnesia fluormica and fluorapatite became the main crystalline phases, and the minor phases including Mg-Zn ferrite, t-ZrO2 and m-ZrO2, etc.also presented in the glass-ceramic. This material possessed high strength and toughness, good machinability and magnetism, which could stimulate formation of new bone, and was good substitute of bone restorations. Bioassay and in vitro test indicated that the glass-ceramic in K2O-MgO-CaO-SiO2-P2O5-F system was bioactive and biocompatible. CONCLUSION: ZnO, Fe2O3 and ZrO2 additives play a significant role in changing crystalline structure, enhancing strength,toughness and machinability of machinable bioglass-ceramic and generating magnetism.

Objective To evaluate the clinical efficacy of Yangyin Yiqi mixture and western medicine in the treatment of oral lichen planus(OLP)and its effect on the levels of interferon -γ(IFN -γ)and interleukine -10 (IL -10)in serum and saliva.Methods Sixty patients with OLP were randomly divided into control group(n =30) and treatment group(n =30).The control group was treated with triamcinolone acetonide and lidocaine,local injec-tion.The treatment group was treated with Yangyin Yiqi mixture on the basis of the control group.The treatment lasted two months.After treatment,the clinical efficacy,objective indicators score,levels of IFN -γand IL -10 in serum and saliva,adverse reactions were compared between the two groups.Results The overall response rate of the treatment group (86.67%)was significantly higher than that of the control group (63.33%)(χ2 =11.64,P <0.01).After treatment,the two groups'objective index score significantly reduced(t =8.52,12.51,all P <0.01),and the treat-ment group's objective indicators rating was significantly lower than the control group (t =4.38,P <0.05).After treatment,the levels of IFN -γin serum and saliva were (25.39 ±1.29)pg/mL and (12.76 ±1.28)pg/mL,which were significantly increased in the treatment group (t =10.35,8.15,all P <0.01),so did the control group (P <0.05).And the levels of IL -10 in serum and saliva were (27.54 ±1.82)pg/mL and (9.92 ±0.86)pg/mL,and the levels were significantly decreased in the two groups after treatment (t =8.76,9.39,all P <0.01,t =4.65,4.94,all P <0.05).And levels of IFN -γin serum and saliva of the treatment group were significantly higher than those of the control group (t =4.68,4.32,all P <0.05),and levels of IL -10 in serum and saliva of the treatment group were significantly lower than those of the control group (t =5.41,5.25,all P <0.05).During treatment,there were no sig-nificant adverse reactions.Conclusion Yangyin Yiqi mixture combined with western medicine has definitive clinical efficacy in the treatment of OLP.It can significantly increase the level of IFN -γand reduce the level of IL -10 in serum and saliva in patients,so provide theory value for treatment of OLP.

Objective To determine the relationship between neuronuscular block induced by cisatracurium for tracheal intubation during anesthesia induction and types of myasthenia gravis (MG).Methods Sixty-five patients of both sexes with MG,aged 20-75 yr,weighing 53-92 kg,with body height of 155-185 cm,of American Society of Anesthesiologists physical status Ⅰ or Ⅱ,undergoing elective videoassisted thoracoscopic thymectomy,were enrolled in the study.Among the 65 patients,there were 8 patients with ocular MG (type Ⅰ),19 patients with mild generalized MG (type]Ⅱ a),33 patients with subacute generalized MG (type Ⅱ b),2 patients with acute MG (type Ⅲ) and 3 patients with late severe MG (type Ⅳ).Neuromuscular monitoring was initiated when the patients lost consciousness after induction of anesthesia.Cisatracurium was administrated with the initial dose of 0.05 mg/kg,and if T1 depression was less than 95％ within 6 min,cisatracurium 0.015 mg/kg was intravenously injected until T1 depression was more than 95％.The patients were then tracheally intubated.The amount of cisatracurium consumed for intubation,onset time (from the beginning of cisatracurium injection to T1 depression ＞95％) and recovery time (recovery of T4/T1 to 25％ of control height) of neuromuscular block were recorded.T1 depression ＞ 95％ within 6 min after administration of 1-fold ED95 cistracuriun was defined as sensitivity to muscle relaxants.The requirement for cistracurium ＞ 1-fold ED95 when T1 depression ＞ 95％ was defined as insensitivity to muscle relaxants.The proportion of sensitivity/insensitivity was calculated.Results There was no significant difference in the amount of cisatracurium consumed for intubation and onset time and recovery time of neuromuscular block between patients with type Ⅰ and those with type Ⅱ a (P＞0.05).Compared with patients with type Ⅰ and type]Ⅱ a,the amount of cisatracurium consumed for intubation was significantly decreased,the proportion of sensitivity/insensitivity was increased,the onset time was shortened,and the recovery time was prolonged in patients with type Ⅱ b (P＜0.05).Conclusion With the severity of MG,the consumption of cisatracurium is gradually decreased when used for tracheal intubation during anesthesia induction,and the sensitivity is gradually increased in the patients with MG.
