ABSTRACT
Taking the Sixth Affiliated Hospital of Sun Yat-Sen University as an example,the paper gives detailed examples in clinical and scientific research fields to indicate that the effective utilization of medical data through function reconstruction of the Electronic Medical Records (EMR) system not only brings conveniences to clinical and scientific researchers,but also strengthens medical protection for patients.
ABSTRACT
Objective To compare the operative precision between pioneer drilling guiding and full navigation guiding plates in the flapless immediate implantation. Methods Data of 50 immediate implants, which were implanted from 47 outpatients (50 implants) of Tianjin Stomatological Hospital from 2014 to 2016 were retrospectively analyzed. The patients were conducted on the pioneer drilling guiding system (22 implants) and full navigation guiding sytem (28 implants). The cone beam CT (CBCT) was preliminarily taken and modeled for each patient. All of the patients underwent implant surgery after making guiding plates by three-dimensional reconstruction, simulation planting design and the application of digital rapid prototyping technology. Cavity preparations were made by pioneer drilling and full navigation assisted with planting drills respectively to finish implantation. The post-operative CBCT was taken and performed the three-dimensional reconstruction. The implantation precision guiding by two systems were compared. Results All of the 50 immediate implants were successfully completed with the guiding plates. Implant mucositis appeared in one case after 3 months of temporary repair, and after the targeted therapy, the final repair was finished. The rest cases were finally completed. No implant was loose or fell off. The deviation was less in neck apex and root apex angle in full navigation group than that of pioneer drilling guiding group (P<0.01). But there was no significant difference in axial angle between the two groups after navigation and implantation (P>0.05). Conclusion The digital surgical guiding plates provide nice technical support for the application of the flapless immediate implantation. And the full navigation system has higher precision than that of the pioneer drilling navigation system.

ABSTRACT
Objective To compare the growth velocity of low birth weight premature (LBWP),mature low birth weight (MBLW)and normal birth weight(NBW)infants and to explore the intervention mode for low birth weight (LBW)infants. Methods 1 133 Infants were divided into LBWP group,MBLW group and NBW group.The growth velocity of weight, height and head -circle were compared.Results The growth velocity of LBW group was greater than that of NBW group (P <0.05).Head circumference of LBWP group was the same as NBW group when they were 1 year old.The growth velocity of LBWP group was greater than that of MBLW group(P <0.05 )and the growth velocity of LBWP group was significantly greater than that of MBLW group when they were 1 year old (P <0.01).Conclusion LBWP infants have greater growth velocity potential than MBLW and NBW infants.It's necessary to pay more attentions to the growth velocity of MLBW infants.
ABSTRACT
<p><b>OBJECTIVE</b>To study the effects of limb ischemia preconditioning on pulmonary free radicals and cytokine levels during lung ischemia-reperfusion injury in rabbits.</p><p><b>METHODS</b>Eighteen healthy rabbits were randomly divided into three groups: control group (group C, n = 6), ischemia/reperfusion group (group I/R, n = 6), limb ischemia preconditioning group (group L, n = 6). At the end of experiments, the wet to dry-weight ratio (W/D), activities of superoxide dismutase (SOD) and myeloperoxidase (MPO), levels of malondialdehyde (MDA) and the contents of cytokines (TNF-α, IL-6, IL-8 and IL-10) were determined in lung tissues. Protein levels of bronchoalveolar lavage fluid and serum were measured to calculate the lung permeability index. Pathologic changes of lung tissues were also observed.</p><p><b>RESULTS</b>Compared to the group I/R, the lung tissue W/D ratio, MPO activity, lung permeability index, MDA and the cytokines (TNF-α, IL-6 and IL-8) levels were significantly decreased in group L (P < 0.05), while the SOD activity (P < 0.05) and IL-10 contents were significantly increased (P < 0.01). There was no statistical difference in the changes of the above parameters between group L and group C (P > 0.05). The morphologic damages were significantly reduced in group L than that in group I/R.</p><p><b>CONCLUSION</b>Limb ischemia preconditioning has protective effect against lung ischemia-reperfusion injury, which may at least in part through inhibiting the release of oxygen-derived free radicals and pro-inflammatory cytokines (TNF-α, IL-6, IL-8) and increasing the production of anti-inflammatory cytokine IL-10.</p>
