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.

Objective To observe the therapeutic effect of injection of consciousness promoted drug through carotid artery on persistent vegetate state (PVS).Methods33 PVS cases were divided into the treatment group (n=15) and control group (n=18). All patients were treated with routine therapy, but the treatment group added with injection of consciousness-promoted drug through the carotid artery. The therapeutic effects of two groups were evaluated.ResultsAfter the treatment, the therapeutic effects of patients in two groups were better than that of before treatment (P<0.05), and the treatment group was better than control group(P<0.05).ConclusionInjection of consciousness-promoted drug through the carotid artery is effective to PVS patients.

Objective:To observe the clinical efficacy of morpholine nidazole in the treatment of infection after radical resection of perianal abscess.Methods:Thirty patients diagnosed with perianal abscess were randomly divided into the observation group(given intravenous infusion of morpholine nidazole) and the control group(given intravenous infusion of ornidazole).Results:There was no significant difference in postoperative wound infection rate between the observation group and the control group ( P>0.05). There was significant difference in wound healing quality between the two groups on the 2 d and 7 d after the operation ( P<0.05). There was no significant difference in WBC and neutrophil counts between the two groups ( P>0.05), and the WBC and neutrophil counts in the two groups were significantly lower on the 7th day after the operation than before the treatment, and the observation group was significantly lower than the control group ( P<0.05). After treatment, there was no significant difference in the clearance rate of escherichia coli, klebsiella pneumoniae, bacteroides fragile and staphylococcus aureus in the observation group ( P>0.05), but there was significant difference in the overall bacterial clearance rate compared with the control group ( P<0.05). The incidence of adverse reactions in the observation group was significantly lower than that in the control group ( P<0.05). Conclusions:The use of morpholinidazole in patients with perianal abscess is effective and safe.

Aim To research the protective effect and mechanisms of taurine on myocardial ischemia and reperfusion injury in rats. Methods Myocardial ischemia reperfusion models were established in SD rats. The effects of taurine on the size of myocardial infarction and the changes of activity of SOD , and the levels of MDA and NO in myocardium and plasma of rats with myocardial ischemia and reperfusion injury were observed. Results In rats with myocardial ischemia and reperfusion injury, the taurine could reduce the size of myocardial infarction (P

ObjectiveTo investigate and evaluate the result and the possibility of the clinical application of autologous chondrocyte implant (ACI).MethodsFrom November 2007 to June 2009,6 cases of knee articular cartilage defect were treated with ACI,including 2 males and 4 females with an average age of 39.5 years (range,19-55).All the defects were located on the condyles of femur with a mean size of 7.3 cm2 (range,3.8-11.6).ACI comprises a two-stage procedure:chondrocytes are first harvested from the non-load bearing area of the joint,expand in vitro to acquire enough cells,and then the chondrocytes are implanted.The defect of cartilage were covered with bone membrane and fixed with sutures and fibrin albumen glue.Lysholm score system,International Knee Documentation Committee (IKDC) grading system,and MRI were used to evaluate the effect of ACI,6 and 12 months post-operatively.ResultsAll the patients were followed up.The clinical outcomes of the 6 and 12 months follow-ups demonstrated increased of clinical scores.The MRI follow-up showed good filling of the defect with tissue having the imaging appearance of cartilage in all patients.Only one patient suffered adhesion,because she refused to finish rehabilitation exercises as our treatment advises.ConclusionAs the clinical effect of ACI for knee cartilage defect is satisfied,the ACI may be a good choice for treating knee cartilage defect in future.It is very important to control the indications strictly and guarantee to finish the post-operative rehabilitation exercises.

RNA-Sequencing (RNA-Seq) is a newly-developed method in transcriptome research, it can afford more accurate transcription information and be more quickly by using Next-generation Sequencing (NGS) technology. RNA-Seq has been widely used in various biological fields. Genuine traditional Chinese medicines (TCM), with good quality and therapeutic effect, were always praised highly and used by famous physicians. The geo-herbalism formation of TCM is based on the product of the gene expression at specific space and time. So it has been a research hotspot to analyze the mechanism of biosynthesis through RNA-Seq in the study on the secondary metabolism of medicinal plant. This article mainly illustrates the RNA-Seq and its advantages, it also discusses the potential application in genuine TCM, and it can provide useful information for other researchers.

OBJECTIVETo evaluate that the effect of formula of removing both phlegm and blood stasis in improving cardiac function of Chinese mini-swine with coronary heart disease of phlegm-stasis cementation syndrome.

METHODTotally 36 Chinese mini-swine were randomly divided to six groups: the normal control group, the model group, the Danlou tablet group, and Tanyu Tonzhi Fang(TYTZ) groups with doses of 2. 0, 1. 0 and 0. 5 g kg-1, with six in each group. Except for the normal control group, all of other groups were fed with high-fat diet for 2 weeks. Interventional balloons are adopted to injure their left anterior descending artery endothelium. After the operation, they were fed with high-fat diet for 8 weeks to prepare the coronary heart disease model of phlegm-stasis cementation syndrome. After the operation, they were administered with drugs for 8 weeks. The changes in the myocardial ischemia were observed. The changes in the cardiac function and structure were detected by cardiac ultrasound and noninvasive hemodynamic method.

RESULTCompared with the normal control group, the model group showed significant increase in myocardial ischemia and SVR and obvious decrease in CO, SV and LCW in noninvasive hemodynamic parameters (P <0.05 or P <0.01). The ultrasonic cardiogram indicated notable decrease in IVSd, LVPWs, EF and FS, and remarkable increase in LVIDs (P<0. 05 orP<0.01). Compared with the model group, TYTZ could reduce the myocardial ischemia, strengthen cardiac function, and improve the abnormal cardiac structure and function induced by ischemia (P <0. 05 or P <0. 01).

CONCLUSIONTYTZ shows a significant effect in improving cardiac function of Chinese mini-swine with coronary heart disease of phlegm-stasis cementation syndrome. The clinical cardiac function detection method could be adopted to correctly evaluate the changes in the post-myocardial ischemia cardiac function, and narrow the gap between clinical application and basic experimental studies.
