3.Thyroid autoantibodies: adverse effects on pregnancy outcomes and child development and its intervention
Chinese Journal of Endocrinology and Metabolism 2012;28(5):441-444
Thyroid autoantibodies (TAA) in euthyroid women were associated with several adverse pregnancy outcomes,such as miscarriage,preterm birth.Maternal TAA frequently results in transient mild elevation of serum TSH above the normal reference value in women during pregnancy and in infants born in the first month of life,and may affect neuropsychological development of their offspring.The cause is still unclear.Medical interventions on TAA involve levothyroxine or selenium supplementation. The article reviews the effects of maternal thyroid autoantibodies on pregnancy outcomes,as well as on neonatal thyroid status,and neuropsychological development of the fetus and neonate,and summarizes therapeutic strategies used to intervene maternal thyroid autoimmunity.

5.Three-dimensional finite element analysis on the stress of mandibular first molar restored with different locations and numbers of gold alloy posts and cores
Chinese Journal of Tissue Engineering Research 2017;21(22):3501-3506
BACKGROUND:The design of post and core of the molar is affected by various factors,including the effect of the number of posts on the retention force and the effect of the number of posts on the dentin stress and distribution.OBJECTIVE:To make a mechanical analysis on the three-dimensional finite element models of the mandibular first molar defect restored with different numbers and locations of gold alloy posts,cores and all-ceramic crown.METHODS:Cone-beam CT based three-dimensional finite element models of post and core restored first mandibular molars were established,with seven different post designs.According to the numbers and location of gold alloy post inserted into root canal,a single post was placed at the mesial buccal root in group A,a single post at the mesial tongue root in group B,a single post at the distal root in group C,two posts at the mesial buccal root and the distal root in group D,two posts at the mesial buccal root and mesial tongue root in group E,two posts at the mesial tongue root and the distal root in group F,one post respectively at the mesial buccal root,mesial tongue root and distal root in group G.The von Mises criterion was applied for comparing the maximum yon Mises stress value of dentin and stress concentration areas in the seven models which restored with golden alloy posts and cores with all-ceramic crown under the maximum (600 N),vertical (225 N),inclined (225 N) and horizontal (225 N) loads.RESULTS AND CONCLUSION:Under vertical,inclined and horizontal direct loads,the maximum stresses on the remaining dentin in group C were significantly lowest,compared with the groups A and B.The maximum stresses on the remaining dentin changed irregularly with the variation of the numbers and location of posts,when the mandibular first molar defect was restored with all-ceramic crown with gold alloy posts and cores.Under the horizontal load,the maximum Von Mises stress value of the dentin increased remarkably.Under the horizontal load,the maximum stresses on the remaining dentin in group E were the highest.To conclude,the numbers and location of posts and cores have influence on magnitude and distribution of stress,when the mandibular first molar defect is restored with all-ceramic crown with gold alloy post and core.

Objective To summarize the experience of use of partial cardiopulmonary bypass for surgery of descending thoracic aneurysm. Methods Thirty five patients were undertaken surgery of descending thoracic aneurysm using partial cardiopulmonary bypass and beating-heart technique in our hospital. The partial cardiopulmonary bypass includes left heart bypass (left atrial to femoral artery bypass), pulmonary artery to femoral artery bypass, femoral vein to femoral artery bypass. Results Only one patient died, the other thirty four patients experienced an uneventful recovery. There was no any complication related to partial cardiopulmonary bypass. Conclusion The use of partial cardiopulmonary bypass for surgery of descending thoracic aneurysm can reduce and avoid the complications of nervous system and urinary system effectively.

BACKGROUND:The location of residual dentin may affect stress distribution of tooth root. <br> OBJECTIVE:To make a three-dimensional finite element analysis of gold al oy post-core and al-ceramic crown in the repair of structure defects of the mandibular first molar, and to provide a guideline for planning restoration for such kind of tooth structure defects. <br> METHODS:Three-dimensional finite element models of the restored first mandibular molars were constructed by CT image reconstruction technique. Then MIMICS software was used to separate the areas and finish the three-dimensional calculation. GEOMAGIC software was also applied to modify and generate a NURBS surface in each patch. Al components of the models were assembled under the ANSYS preprocessor. The Mohr strength theory was applied for comparing the maximum Mohr stress value of dentin and stress concentration areas in six models under different simulating loads. <br> RESULTS AND CONCLUSION:The restoration effects in six models were compared, the maximum Mohr stress value of dentin and stress concentration areas were not obviously different. The location of residual dentin has little influence on the stress value and distribution, when restored by gold al oy post-core and and al-ceramic crown.

Carotid artery calcification is a calcium deposition on arterial wals. It has a great clinical significance when it occurs within atherosclerotic plaques, which is a marker of the progressive atherosclerosis. In recent years, the studies on the mechanism of carotid artery calcification and imaging detection methods are continuously advancing and being updated. In addition, the correlation between carotid plaque calcification and ischemic cerebrovascular disease and the effect on its therapeutic decisions are also the research foci. However, there have been controversies about the advantages and disadvantages of carotid artery calcification. Some researchers believe that carotid artery calcifications are a protective factor, but others believe that they may promote the plaque vulnerability. This article reviews the recent progress in research on carotid artery calcification from the above aspects.

Objective:To observe the influence of Xinfeng capsule(XFC) on pulmonary HRCT images and cytokines(TNF-?,IL-10) in blood serum adjuvant arthritis rats.Methods:60 rats were averagely divided into normal control group,model control group,methotrexate(MTX) treated group,tripterygium wilfordii polycoride tablet(TPT) treated group, XFC treated group,12 in each.Except for the rats of normal group,the others were intracutaneously injected with 0.1 ml of Freund’s complete adjuvant in the right hindlimb.After 19 days,different drugs were given to all rats. Pulmonary HRCT images were obtained and the blood samples were reserved for assaying cytokines.Results:In model control group ,the lungs’ outlines weren’t clear and the blood vessels expanded with the edges of them being obscure and unregular. There were high density images shaped as rope and slip in lungs of model control group rats and the pleura near the images were a little thickening. In MTX treated group, there were high density images shaped as slice along pulmonary veins. The veins of the blood vessels were obscure and the edges were unclear. In TPT treated group,there were multiple high density images shaped as tubercle and slice and the boundary were not clear. In XFC treated group, the lungs’ outlines were clear and the veins were well-distributed. High density images shaped as spot were found in part lungs. Compared with normal control group,tumor necrosis factor-?(TNF-?) in blood serum ascended obviously in model control group(P0.05).Conclusion:XFC eliminates swelling by down-regulating the levels of TNF-?, up-regulating the levels of IL-10, restraining the inflammatory reaction.In adittion,cytokines participated in forming pulmanory fibrofication.So the changes of pulmanory HRCT images were also improved at the same time.
