OBJECTIVE: To investigate the progress of clinical application of implant during distraction osteogenesis in the jaw bones, and to evaluate its biocompatibility.METHODS: The first author retrieved CNKI database from 1989 to 2009 in Chinese and Medline database from 1989 to 2009 in English with the key words of "jaw, distraction osteogenesis, treatment". A total of 56 articles were screened according to inclusion and exclusion criteria. Finally, 20 articles concerning treatment progress of distraction osteogenesis and clinical application of implant were included.RESULTS: Distraction osteogenesis implants contained intraoral or extraoral distraction device, which could be used for distraction of transport plate. A distraction was selected in accordance with patients' condition and requirement. Distraction osteogenesis had been an important manner for complicated tooth jaw facial deformity and jaw defect in oral dentofacial surgery and Orthodontic treatment. It could have effective osteogenesis in combination with various systemic therapy, local therapy and physical therapy. Presently, distraction osteogenesis implants were metal materials. Metal implants have great advantages in preventing bacterium growth, keeping implant fixation and distraction effects, and the price was high. However, the cost of Ni-Ti memory alloy wire was lower compared with common retractors. The fixing device and alloy wire closely adhered to the bone could be completely implanted into tissues, with the advantages of anti-infection and completely closing the exterior and interior wound. CONCLUSION: Distraction osteogenesis is a new method for treating dental and craniofacial hypodevelopment straightening of teeth and for repairing jaw bone defect deformation. Biocompatibility of metal implants was good such as internal small Ni-Ti memory alloy wire. The biocompatibility of other types of implants should be improved.

Osteoarthritis(OA) is a chronic progressive disease in the elderly, there are still no effective therapy for this disease. The objective of this article was to review progress in the clinical studies and therapies on the disease, especially NSAID therapy and total knee replacement.

BACKGROUND:No ideal drugs can be used in the prevention and treatment of aseptic loosening of artificial joints. Some researchs showed that erythromycin has strong inhibitory effects on periprosthetic osteolysis. Its antibacterial activity, however, limits its application in artificial joint loosening prevention. LY267108 is a new type of erythromycin derivatives, eliminates the antibacterial activities, and retains the anti-inflammatory activity.
OBJECTIVE:To evaluate inhibitory effect of LY267108 on nuclear factor kappa B during osteoclast activation.
METHODS:RANKL and macrophage colony-stimulating factor were added to RAW264.7 cellline of a mouse model induced by osteoclasts. Simultaneously, different concentrations of alendronate sodium, erythromycin and LY267108 were cocultured for 48 hours. The activity of nuclear factor kappa B and content of intracytoplasmic inhibitory subunit of nuclear factor kappa B alpha were measured by electrophoretic mobility shift assay and western blot assay.
RESULTS AND CONCLUSION:LY267108 has a strong inhibitory effect on nuclear factor kappa B. 10 mg/L LY267108, 25 mg/L erythromycin and 10 mg/L alendronate sodium had similar inhibitory effects on nuclear factor kappa B, which was obviously stronger than 10 mg/L erythromycin. However, 25 mg/L LY267108 had strongest inhibitory effects. No significant difference in intracytoplasmic inhibitory subunit of nuclear factor kappa B alpha levels was detected among 10 mg/L LY267108, 25 mg/L erythromycin and 10 mg/L alendronate sodium groups, but was stil apparently higher than 10 mg/L erythromycin group. Levels of intracytoplasmic inhibitory subunit of nuclear factor kappa B alpha were highest in the 25 mg/L LY267108 group. Results indicated that LY267108 in the process of osteoclast activation had stronger inhibitory effects on nuclear factor kappa B compared with erythromycin, and its safety was higher than alendronate sodium. Simultaneously, LY267108 did not have antimicrobial activity, and became a potential ideal drug for prevention and treatment of aseptic loosening of artificial joints. However, the inhibitory effects of LY267108 on the degradation of inhibitory subunit of nuclear factor kappa B alpha would be a mechanism of inhibiting the activation of nuclear factor kappa B.

Objective To investigate the clinical effect of voriconazole in the treatment of invasive fungal infections in lung cancer patients with radiotherapy and chemotherapy,to provide a reference for clinical treatment. Methods The clinical data of 64 lung cancer patients with radiotherapy and chemotherapy with invasive fungal infec-tions were retrospectively analyzed.According to the treatment methods,they were divided into control group and observation group,32 cases in each group.Fluconazole treatment was used in the control group,and the observation group used voriconazole therapy.The overall response rate,time to return to normal white blood cells and other indica-tors of liver and kidney function were compared between the two groups.Results The effective rate of the observation group was 81.25%,which was significantly higher than 68.75% of the control group,the difference was statistically significant(χ2 =5.876,P=0.008).The temperature recovery,cough disappeared,leukocyte recovery time of the observation group were (3.61 ±0.61)d,(6.11 ±0.81)d,(7.85 ±0.92)d,which were significantly shorter than those of the control group,the differences were statistically significant(t=4.145,P=0.025;t=4.045,P=0.027;t=4.385,P=0.021).The treatment of the two groups had mild liver and kidney damage,and there was no signifi-cant difference between the two groups(all P>0.05 ).Conclusion Voriconazole treatment has good clinical effect for lung cancer patients after radiotherapy and chemotherapy with invasive fungal infections,the treatment period is short,but with mild liver and kidney function impairment,the treatment should strengthen the monitoring.

Objective To investigate the etiology of the nosocomial infection and immune function changes anus and anal after operation.Methods 130 patients who needed anus and anal canal surgery were recruited in the study.The clinical data were recor-ded and postoperative nosocomial infection data were observed,including infection type,distribution,pathogenic analysis and im-mune function.Results A total of 67 cases of nosocomial infection occured,the infection rate was 51.5% (67/130),the main types of infection were perineal wound infection,abdominal infections and pelvic infections,urinary tract and vaginal infections were rare. 93 isolates were collected,of which gram-negative bacilli accounted for 67.7% (63/93 ),including bacteroides fragilis (21.5%), Escherichia coli (18.3%),Pseudomonas aeruginosa (10.8%);Gram-positive bacteria accounted for 23.7% (30/93 ),including Staphylococcus aureus(17.2%),Staphylococcus epidermidis(6.5%);5 fungi were isolated accounting for 5.4%,other strains ac-counted for 3.2%.All the immune parameters detected in patients with postoperative nosocomial infection were statistically differ-ent from those before infection(P <0.05)except for IgM(P >0.05).Conclusion The incidence of nosocomial infection was rela-tively high in patients who had anus and anal canal surgery,which could serious affect the patients'outcomes,preventive and control measures should be taken in clinical practice.
