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.

Functional near-infrared spectroscopy is a non-invasive optical brain function detection technology,which can do multi-point measurement of changes on cerebral cortical area corresponding to the oxygenation of the blood hemoglobin and deoxygenated hemoglobin concentration,and then reflect the state of brain cortex function.Its greatest advantage is to allow the subjects head moving in a certain range,especially suitable for children.At present this technology could be applied to clinical pediatric,such as epilepsy,autism,attention deficit/hyperactivity disorder,neonatal disease,neurosurgery and cardiovascular surgery,etc.Functional near-infrared spectroscopy technology will have more applications in the field of research on brain function.

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.

AIM: To clarify the role and mechanism of hippocampus in the formation of P3-like. METHODS: (1) The hippocampal and parietal P3-like were simultaneously recorded by chronically implanted electrodes in rats. (2) In forebrain ischemia/reperfusion model, the effects of the selective damage of hippocampal CA1 subfield on the hippocampal and parietal P3-like were examined. (3) The changes of hippocampal and parietal P3-like after the inhibition of acetylcholine activity in the septo-hippocampal pathway by intraperitoneal injection of atropine (30 mg/kg) were also detected. (4) The changes of conditional active avoidance response was tested by shuttle-box following forebrain ischemia/reperfusion. RESULTS: (1) The peak latencies of hippocampal and parietal P3-like were prolonged after forebrain ischemia/reperfusion. (2) The polarity of hippocampal P3-like were reversed after the inhibition of acetylcholine activity in the septo-hippocampal pathway by atropine. (3) The prolongation of P3-like peak latency was closely related to the lowering of the score of conditional active avoidance response after forebrain ischemia/reperfusion. CONCLUSION: (1) The formation of P3-like depends on the integrity of hippocampus formation. (2) Hippocampus is not the only generator of P3-like, P3-like could be produced in multiple way. (3) The activity of acetylcholine in the septo-hippocampal pathway has notable effects on the formation of P3-like. (4) P3-like could be used as the sensitive marker of cognitive function.

Objective To explore the clinical application of mirabilite abdominal hot compression bag designed by ourselves for the moderately severe acute pancreatitis ( MSAP ) or severe acute pancreatitis ( SAP) .Methods Seventy MSAP and SAP patients were randomly divided into the observed and control groups according to the admission date.Each group included 35 patients.All the patients received the routine treatment.The patients in observed group received the treatment of compression action on abdomen by mirabilite abdominal continual hot compression bag designed by ourselves, while the traditional mirabilite hot compression action was used in the control group.The APACHEⅡscore and the levels of plasma CRP, IL-1, IL-6 and TNF-αof all patients on the 1st, 3rd, 6th, and 9th day after being admitted, the rate of complications including the intra-abdominal hypertension (IAH), pancreatic pseudocysts (PPC) and pulmonary infection, the recovery time of intestinal function and mean hospitalization time were all recorded and the therapeutic efficacy was compared between the two groups.Furthermore, the therapeutic effects of MSAP and SAP were compared between two groups.Results The APACHEⅡscore and the levels of plasma CRP, IL-1, IL-6 and TNF-αwere not statistically different between the two groups on the 1st day after hospitalization.The APACHEⅡscore and the levels of plasma CRP, IL-1 and TNF-αon the 3rd day in the observed group were significantly lower than those in the control group(P<0.05 or <0.01).The APACHEⅡ score and the levels of plasma CRP, IL-1 , IL-6 and TNF-αon the 6th day in the observed group were significantly lower, comparing to those in the control group.The levels of serum IL-1 and TNF-αin the observed groups were significantly lower than those in control group on the 9th day.All the differences above were statistically significant ( P<0.05 or <0.01).In the observed group, 4 cases (11.4%) had IAH and 7 cases (20.0%) developed other complications.The time of intestinal recovery and mean hospitalization was (4.9 ±0.8)d and (13.1 ±2.1)d, respectively, in the observed group.In the control group, 11 cases (31.4%) had IAH and 10 cases (28.6%) had other complications, and the time of intestinal recovery and mean hospitalization was (5.5 ±0.8) d and (15.4 ±3.9)d,respectively,.The rate of IAH, intestinal function recovery time and hospitalization time in the observed group were significantly less than those in control group (P<0.05 or <0.01).There was no statistical difference on other complications between the two groups.The intestinal function recovery time and hospitalization time of MSAPs in the observed group were significantly less than those in control group [(5.0 ± 0.8)d vs (5.5 ±0.8)d, P=0.03; (12.7 ±1.7)d vs (15.2 ±3.6)d, P=0.02].The APACHEⅡ score and the levels of plasma CRP, IL-1, IL-6 and TNF-αof SAPs were not statistically different between the two groups.Conclusions The application of the mirabilite abdominal continual hot compression bag could alleviate inflammatory response of MSAP and SAP, decrease the rate of IAH, improve the intestinal function recovery time,and shorten the hospitalization time.
