1.A comparative study of wire and divider methods applied in orthodontic dental model measurement
Journal of Practical Stomatology 2001;0(03):-
Objective:To compare the difference between the measurement methods of wire and divider applied in the measurement of arch length at orthodontic dental model analysis.Methods:80 pairs of dental models were selected,including 40 normal occlusion models and 40 crowded models.The arch length of every model was measured by the wire and divider methods respectively,and the casual error and paired t test was subsequently employed to compare the difference between the measurements data.Results:The variance coefficients of the dental lengths measured by the divider method was larger than those measured by the wire method in both crowding and normal occlusion(P
2.Effect of femoral offset on hip joint function reconstruction after arthroplasty in femoral neck fractures
Chinese Journal of Orthopaedic Trauma 2008;10(8):711-714
Objective To study the effect of femoral offset reconstruction ON the Harris hip score and the hip ROM (range of motion) after artificial hip replacement in femoral neck fractures. Methods Follow-ups were conducted for 47 patients who had undergone artificial hip replacements for their unilateral femoral neck fractures. We took X-ray pictures to compare the femoral offsets at the affected and unaffected hips. The operated hips were evaluated by the Harris hip score. Statistical analyses were performed with SPSS l2.0 software. Results The Harris hip score of the operated hip was positively related to femoral offset reconstruction(t=7.25,P<0.001).There was a significant and positive correlation between femoral offset and the hip abductor ROM(r=0.80,P<0.001).The rate of femoral offset reconstruction had no significant difference between total hip arthroplasty and bipolar hip arthroplasty (χ2=0,P>0.05).Conclusions Reconstruction of femoral offset after artificial hip replacement in the femoral neck fractures can improve funetional recovery and ROM of the hip. Femoral offset reconstruction is uncorrelated to the selection of total hip arthroplasty or bipolar hip arthroplasty.
3.Advances of death-associated protein kinase in tumor
International Journal of Surgery 2008;35(8):559-561
Death-associated protein kinase (DAPK) is a muhidomain calcium/calmodulin (CaM)-de- pendent Ser/Thr protein kinase with an important role in apoptosis regulation and tumor suppression. DAPK may serve as a diagnostic and prognostic tool to evaluate disease severity, progression, metastatic rate, and re- currence, and may serve as a target for therapeutic intervention.

Neovascular age-related macular degeneration (AMD) is the main cause of vision loss in AMD patient.Now,the application of anti-vascular endothelial growth factor(VEGF) has become the preferred therapy for the treatment of neovascular AMD,and it has been proved to improve the visual acuity and reduce the blindness rate.But the formation of choroidal neovascularization (CNV) in AMD is a comprehensive and integrated pathological process.It is difficult to cure the CNV with only anti-VEGF drug for all the neovascular AMD patients.Therefore,the targeting drugs toward other signal pathway associated with CNV are being in different phases of clinical trials.Resent years,with the development of science and technology,small interference RNA(siRNA) and genome technology has been applied to treat neovascular AMD and show a potential prospect,and gene therapy and stem cell therapy are the most remarkable and predominant ways for AMD.Doubtlessly,these therapies offer novel choice for the management of neovascular AMD.

Objective To compare the effect of bupivacaine and levobupivacaine for caudal anesthesia in infant and children.Methods Forty patients with age 3-6 years old in the state of ASA Ⅰ grade were randomly divided into bupivacaine group and levobupivacaine group,each 20 patients.Both groups received respectively bupivacaine or levobupivacine with the same concentration and volume.The blood pressure,heart rate and pulse oxygen saturation were monitored during the operation.The degree of pain and motor was assessed after the operation.Results Bupivacaine and levobupivacaine for caudal anesthesia in infant and children could provide good analgesic effects.The scores of pain was similar between the two groups and had no statistic significance (P > 0.05).The scores of motor block in bupivacaine group was significantly higher than that in levobupivacaine group after anesthesia 60,90,120 min [(1.5 ±0.6) scores vs.(0.9 ±0.3) scores,(1.0 ±0.8) scores vs.(0.1 ±0.5) scores,(0.6 ±0.5) scores vs.(0.0 ±0.7)scores],there was significant difference (P < 0.05).Conclusions Bupivacaine and levobupivacaine have the same analgesic potency.Levobupivacaine is better than bupivacaine in motor block.

Articular cartilage repair is limited. Current treatments for cartilage defect are less satisfactory, and rarely restore full function or return the tissue to its native normal state. The rise of tissue engineering holds great promise for the generation of functional cartilage tissue substitutes. The history of cartilage tissue engineering and highlights the applications and advantages of various kinds of scaffolds in cartilage tissue engineering, such as native scaffolds, synthesis scaffolds, composite scaffolds and nanometer scaffolds had been introduced. But native scaffolds have weak strength and immunogenicity insufficiency, synthesis scaffolds degrade quickly, whose degrading products have cytotoxicity,which need further improvement. The application of superficial decoration overcomes the disadvantage of some scaffolds to an extend. Composite scaffolds possess the advantages of several scaffolds, it points out the direction of future scaffolds research. The development of Nanometer technique endows newly-synthesis scaffolds with nano-grade, thus it has some advantages and give a new way for the development of tissue engineering. At the end, the problems of these scaffolds, their trend of development and perspective studies were discussed.
