Objective　To manufacture adriamycin-porous tricalcium phosphate (A-PTCP) ceramic drug delivery system (DDS)as a possible method for bone defect treatment after bone tumor operation. Methods　A-PTCP DDS was made from putting adriamycin into PTCP. Thirty rabbits were divided randomly into group A(24 rabbits) and group B(6 rabbits). A-PTCP was implanted in the greater trochanter of the right femur in group A. Adriamycin were injected into veins in group B. Muscle around A-PTCP and plasma were taken out at different period. Adriamycin concentrations in muscle and plasma were measured by high performance liquid chromatography (HPLC). Results　A-PTCP could gradually release adriamycin over 10 weeks. Adriamycin concentrations in the muscle were higher than that in plasma. Conclusion　A-PTCP may be a new method for repairing bone defects after bone tumor operation.

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 explore the effect of clinical nursing pathway (CNP) in perioperative nursing for breast cancer,especially the instructive important role in the rehabilitative excises postoperation and after discharge.Methods In accordance with the standard for the entry and exit of the CNP,102 patients with breast cancer were randomly divided into the experimental group (50 patients) and the control group (52 patients),the experimental group received the care of clinical nursing pathway and the control group received the traditional care.The effect of clinical nursing pathway on the following aspects such as the level of mastering knowledge about hospitalization,self-care ability after discharge,the degree of satisfaction about nursing were compared between the two groups.Results Compared with the control group,the level of mastering knowledge about hospitalization and self-care ability after discharge in the experimental group were significantly better,the degree of satisfaction about nursing reached 98.92%,which was higher than that of the experimental group.Conclusions Application of the full care model with CNP demonstrated good effect on the perioperative nursing for breast cancer,it encourages patients to do the limb functional training,promotes the recovery of disease,and then shortens hospital stay and saves hospital costs.

OBJECTIVE:To observe therapeutic efficacy and safety of Albumin tannate and barm powder in the treatment of infantile acute diarrhea. METHODS:81 cases of infantile acute diarrhea were selected and randomly divided into treatment(41 cas-es)and control group(40 cases). Both groups received routine treatment;treatment group was additionally given Albumin tannate and barm powder orally;control group was additionally given Montmorillonite powder. Clinical efficacy,the taste of drugs and ADR were observed in 2 groups after treatment. RESULTS:There was no statistical significance in total effective rate(97.56%)of treatment group and that (100%) of control group (P>0.05). After treatment,defecation times and urine volume score of treat-ment group were higher than those of control group,with statistical significance(P<0.05). The taste score of Albumin tannate and barm powder(2.93±0.35)in treatment group was significantly higher than(1.25±0.44)in control group,with statistical signifi-cance(P<0.05). No obvious ADR was found in 2 groups. CONCLUSIONS:Albumin tannate and barm powder and Montmorillon-ite powder have good clinical efficacy and safety in the treatment of infantile acute diarrhea. Albumin tannate and barm powder is better than Montmorillonite powder in improving children’s appetite and relieving abdominal pain. Albumin tannate and barm pow-der tastes better when taking,gain a better adherence in the children patients.
