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.

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.

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.

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.

OBJECTIVE: To study the influence of single leaf Asarum himalaicum on the renal function of rabbits. METHODS: Rabbits were divided into three groups. Asarum himalaicum, Asarum heterotropoides and normal saline were intravenously administered to the rabbits of one group respectively. The urine volume per minute, urine pH, urine glucose, protein and red blood cells, BUN, SCr, TXB2, 6-keto-PGF1alpha, TXB2/6-keto-PGF1alpha, endothelin, p-aminohippuric acid clearance rate and phenolsulfonphthalein excretion rate were tested before and after the administration. RESULTS: A certain dosage of single leaf Asarum himalaicum caused acute renal failure in rabbits. The indices tested were significantly different between rabbits administered Asarum himalaicum and normal saline. As compared with the rabbits administered Asarum heterotropoides, the results of indices tested decreased, but without statistical significance, except for SCr. CONCLUSION: The single leaf Asarum himalaicum can cause renal damage to rabbits. Its renal toxicity is lower that that of Asarum heterotropoides.

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.

Objective To study the effects of single leaf Asarum on pulmonary ventilation in experimental rats with syndrome of cold fluid shooting lung. Methods Wistar rats were randomly divided into three groups including singe leaf Asarum group [fed with water extracts of singe leaf Asarum 1 mL/(kg?d)], singe leaf Asarumi Miq group [fed with water extracts of singe leaf Asarumi Miq 1 mL/(kg?d)] and normal saline group [fed with 0.9% normal saline 1 mL/(kg?d)]. After fed continually for 6 days, whole lung of rats were washed with normal saline [7 ℃, 2.5 mL/(kg?d)] and then were perfused for 30 seconds. This treatment was repeated 5 times every 5 minutes to make the model of cold fluid shooting lung. The fluid of perfusion was collected and detected. The changes of TXB2, ET, protein and phospholipids of the fluid were measured before and after lavage. Results TXB2, ET and protein in the perfusing fluid ascended obviously, while phospholipids were low in normal saline group. TXB2 and ET in singe leaf Asarum group and single leaf Asarumi Miq group were less than that in normal saline group (P
