ObjectiveTo evaluate central compartment lymph node metastasis in cN0 papillary thyroid carcinoma(PTC) patients. MethodsThe clinical data of 166 cN0 PTC patients was retrospectively analyzed. ResultsThe central compartment lymph node metastasis rate of age ＜ 45 years group was higher than the group of age≥45 years(39％ vs.22％,P ＜0.05).Tumor size ＞0.5 cm tends to metastasize more often than tumor size ≤0.5 cm(P ＜0.05) ; there was significantly difference in central compartment lymph node metastasis rate between upper pole tumor ( 25％,12/48 ) and middle ( 45％,13/29 ) or lower pole (43％,31/72),P ＜ 0.01. ConclusionscN0 PTC patients with tumor located in middle pole or lower pole,tumor size ＞ 0.5 cm or age ＜ 45 years are at higher risks for central compartment lymph node metastasis.

Objective:To compare the effects of distal movement of canines between elastic traction and canine lace back in the aligning stage of preadjusted appliance. Methods:50 cases with Angle I malocclusion were divided into two groups after first premolar extraction. Patients in both groups were treated by the same kind of preadjusted appliance in the aligning stage. Canine lace back was used in one group and elastic traction in another.Treatment was countinued for 12 weeks.Measurements of the dental models and the cephalograms were conducted before and after treatment.Results:Compared to the canine lace back, the decrease of the width between the cuspids of upper premolars and that between that of lower molars, the increase of the angle of the distally tipped canines and the mesially tipped lower molars and the lingually tipped incisors, the higher speed and larger distance of distal moving canines were achieved more easy with elastic traction. On the contrary, the larger distance of mesial moving molars were attained with canine lace back. The differences of all the measurements above between the two methods were significant(P

Minocycline is the second generation semisynthetic tetracycline antibiotics.A variety of animal models and clinical trials have shown that it has neuroprotective effect.Its mechanism is associated with inhibiting apoptosis, alleviating inflammatory reaction, reducing infarct volume, and alleviating vascular injury.This article reviews the neuroprotective effect of minocycline in preclinical phase and early clinical trials of acute ischemic stroke.

Diabetes mellitus is an independent predictor of high platelet reactivity after antiplatelet therapy in patients with ischemic stroke,and the latter is closely related to the increased risk of recurrence of stroke.The mechanisms of high platelet reactivity in patients with diabetes or insulin resistance are associated with a variety of factors.Some circulating molecules can be used as markers for predicting the reactivity of platelets.Monitoring of platelet reactivity after treatment with new antiplatelet agents may provide basis for individualized antithrombotic therapy in ischemic stroke patients with diabetes or insulin resistance.

Objective T lymphocyte subsets in children with characteristics observed with infec-tious mononucleosis (infectious mononucleosis,IM),to explore its reference value.Methods January 2011 to December 2014 during a pediatric door altogether 115 cases of hospitalized children were divided in-to three groups,51 cases of IMgroup,33 atypical group,31 patients flyers syndrome,selecting outpatient healthy children as 101 cases the control group.For each group T lymphocyte subsets:CD3 + CD4 +,CD3 +CD8 +,CD4 +/CD8 + ratio,analyze the differences between the groups was significant.Results Compared four groups of T lymphocyte subsets (CD3 +,CD3 +CD4 +,CD3 +CD8 +,CD4 +/CD8 + ratio)change char-acteristics,IMgroup,atypical group,flyers syndrome group and the control group,the difference was sta-tistically significance (P <0.05),presence prompts patients significant immune dysfunction;children IM group than in the atypical group,flyers syndrome group CD3 +,indicators of changes in CD3 +CD4 +,CD3 +CD8 +,CD4 +/CD8 + ratio and other more obvious The difference was statistically significant (P <0.05), described IMgroup of children was more severe immune dysfunction;atypical combination Flyer syndrome group,the difference was not statistically significant (P >0.05),two groups of children described in T there was no significant difference in lymphocyte immune.Conclusions T lymphocyte subsets have some reference value in the differential diagnosis of IM,and prompt clinical attention to EB virus infection in chil-dren whose immune function,can help prevent and treat.

Objective To investigate the correlation between serum cystatin C (CysC) levels and cerebral microbleeds (CMBs) in patients with acute ischemic stroke.Methods The patients with acute ischemic stroke were enrolled.Susceptibility weighted imaging was used to identify the presence of CMBs.Particle-enhanced turbidimetric immunoassay was used to detect the levels of serum CysC.Results A total of 485 patients with acute ischemic stroke were enrolled,including 151 (31.1％) with CMBs.The level of serum CysC of the CMB group was significantly higher than that of the non-CMB group (1.24± 0.13 mg/L vs.1.02± 0.11 rmg/L; t=4.261,P＜ 0.001).Multivariate logistic regression analysis showed that the increased serum CysC level was an independent risk factor for the presence of CMBs in patients with acute ischemic stroke (each increase in one standard deviation,odds ratio 4.063,95％ confidence interval 2.142-8.127; P ＜0.001).Multiple linear regression analysis showed that the number of CMBs in patients with acute ischemic stroke increased with the increasing serum CysC level after adjusting for other confounders (r2 =0.361,P =0.017).Conclusions In patients with acute ischemic stroke,the serum CysC levels are independently associated with the CMBs,and the number of CMBs increases with the serum CysC level.

Phage display is a new technology developed in recent years. Random peptides displayed on the filamentous phage surface offer a rich source of molecular diversity in searching for ligands that bind an antibody, receptor and other proteins. The phage display system has been effective in the discovery of various ligands. Potential applications of the peptide library include investigation of the protein protein interactions and discovery of mimetic drug candidates.

Objective To study the effect of bone-marrow mesenchymal stem cell (BMSC) via artery transplantation on behavior changes after ischemic brain injury in mice.Methods 60 mice (C57BL/6) were divided randomly into sham group,brain ischemia group (MCAO group) and stem cell therapy group (BMSC group).The latter two groups were injected respectively with 200 μl PBS or BMSC suspension into common carotid arteries namely when removal suture after middle cerebral artery occlusion model,while sham group was only isolated carotid artery.Infarct size of brain tissue was measured by TTC staining.Focal deficit score,Morris water maze test,the rotating beam test and Rotarod test were resepectively made to evaluate the animal behavior after injury.Results Adequate amounts of BMSCs were harvested by adherence screening method and subculture.Ischemic area of BMSC group ((34.98±12.49) ％) was significantly smaller than that of MCAO group ((42.36±9.41)％) at 2nd day after injury (P＜0.05).Compared with MCAO group,focal deficit score of BMSC group reduced significantly at 3rd day after injury,and got to the most significant differences at 5th day after injury (P＜0.01);escape latency of BMSC group was significantly shortened at 7th day and 14th day after injury in Morris water maze test (P＜ 0.05),meanwhile time percentage,distance percentage in the target quadrant and the times corssing the platform were increased gradually after injury,and reached significant differences at 14th day after injury(P＜0.05);exercise time in Rotarod runner increased at every time point after injury,and reached most significant differences at 14th day after injury(P＜0.01);walking speed in the rotating beam test increased most significantly at 14th day after injury,meanwhile walking distance at 5th and 10th day after injury(P＜0.01).Conclusion BMSC transplantation via carotid artery can significantly improve neural function,learning,balance and motor function after brain injury,which will be a new way of TBI therapy.
