Researches on monoclonal gammopathy of undetermined significance (MGUS) and smoldering muhiple myeloma (SMM) are at a low level although their incidence is high.This review discusses curent biological insights in MGUS/SMM and discusses how the integration of novel biological markers,molecular imaging,and clinical monitoring of MGUS/SMM could facilitate the development of early treatment strategies for high-risk SMM (early myeloma) patients in the future.

Magnetic resonance imaging has shown its important role in both early diagnosis of Alzheimer's disease and revealing the Alzheimer's disease pathogenesis.Structural magnetic resonance imaging include lineal mesure,volume measure and volume rendered.They can detect the abnormal brain structure,especially the change of mesial temporal lobe(hippocampus,amygdale) in early onset of Alzheimer's disease.Recent studies more focused on functional imaging which can find the functional changes in brain.Prior to structural changes,functional changes happen,so it can reflect the sutile pathological process in Alzheimer's disease.The functional imaging mainly refers to magnetic resonance spectroscopy,functional magnetic resonance imaging,diffusion weighted imaging and diffusion tensor imaging.As developing of these new technologies,we know more and more about pathogenesis and biological characteristics of Alzheimer's disease.

Objective To systematically review the short-term and long-term efficacy of eversion carotid endarterectomy (eCEA) and patch carotid endarterectomy (pCEA) for the treatment of carotid artery stenosis.Methods The published literature on eCEA and pCEA control studies in medline,PubMed,Ovid,CNKI and CBM (1970.5-2016.10) databases were retrieved by computers.Two reviewers selected literature and extracted data independently according to the inclusion and exclusion criteria.Cochrane Collaboration Network Special Software Rev Man 5.2 was used to analyze the meta-analysis of short-term and long-term outcome measures.Results A total of 1 137 articles were retrieved.Ten studies were included and analyzed (3 of them were randomized controlled trial).A total of 3 213 patients were enrolled,including surgical intervention 3 299 case/time (1 512 in the eCEA group and 1 787 in the pCEA group).The results of meta-analysis showed that:(1) the mean operative time in the pCEA group was shorter 22±8 min than that in the pCEA group.The intraoperative utilization ratio of shunt tube,eCEA was significantly lower than pCEA,they were 12.6 %(53/421) and 50.2% (357/711) respectively (OR,0.11,95%CI 0.08-0.15,P<0.01).The postoperative incidence of stroke within 30 d (OR,0.42,95%CI 0.23-0.76,P=0.004) and the incidence of stroke after 30 d in eCEA were lower than those in pCEA (OR,0.26,95%CI 0.09-0.78,P=0.02).There was significant difference.(2) eCEA reduced the incidence of restenosis at day 30 after procedure (OR,0.57,95%CI 0.38-0.86,P=0.008).Conclusion Compared with pCEA,eCEA has the advantages of reducing the operation time and lowering the utilization rate of shunt tube.At the same time,eCEA can reduce the occurrence of stroke within 30 d and 30 d after procedure,and significantly reduce the incidence of restenosis.

OBJECTIVE:To study the preparative methods of the long-circulating solid lipid nanoparticles(LSLN)carrying ginkgolides A and B(GAB)and to study the physicochemical characteristics of the GAB-LSLN.METHODS:GAB-LSLN was prepared by ultrasonication or high pressure homogenization.Transmission electron microscopy was employed to study its shape.Particle size,zeta potential,and entrapment efficiency of GAB-LSLN were determined,and its stability after storage under room temperature for 4 weeks was determined as well.RESULTS:The GAB-LSLN prepared by ultrasonication was platelet-shaped and irregular,and that prepared by high pressure homogenization was spherical and regular in shape.The particle diameters of GAB-L SLN prepared by ultrasonication and high pressure homogenization were(219.6?14.3)nm and(173.9?10.4)nm respectively(P0.05).CONCLUSION:High pressure homogenization is superior to ultrasonication in that the prepared GAB-LSLN has small particle size,high stability and high entrapment efficiency.

Objective To detect serum Vaspin level in subjects with normal glucose regulation(NGR)and newly-diagnosed type 2 diabetes mellitus (T2DM) ,and to investigate the association between serum Vaspin and body mass index (BMI), age, gender, glycometabolism and lipemetabolism and insulin sensitivity index. Methods The fasting serum levels of Vaspin were measured in 48 normal controls and 66 T2DM patients using enzyme linked immunosorbent assay ( ELISA ). BMI, waist-hip ratio (WHR) and % body fat were measured,as well as fasting blood glucose (FBG), HBA1C, lipids and insulin levels. Results The fast serum Vaspin concentrations in the obese T2DM patients was ( 1.13 ±0. 25 ) μg/L,which were significantly higher than that in the non-obese T2DM patients (0. 65 ± 0. 13 ) μg/L (P ＜ 0. 01 ). In the NGR group, the fast serum Vaspin concentrations in the obese was (0. 95 ± 0. 11 ) μg/L, which were significantly higher than that in the non-obese (0. 38 ± 0. 18) μg/L( P ＜ 0. 01 ). In the T2DM group, serum Vaspin concentration in females ( [0. 92 ± 0. 35]μg/L) was higher than in males ([0.76 ± 0. 22] μg/L) (P ＜ 0.01 ). In the NGR group, serum Vaspin concentration in females was also higher than that in males ( [1.05 ± 0. 21] μg/L vs [0. 48 ± 0. 14] μg/L) )(P＜0. 01 ). Serum Vaspin level was positively correlated with BMI,WHR,% Body Fat,fasting insulin(FINS)and insulin sensitivity index (ISI) (r = 0. 365,0. 214,0. 238,0. 183 and 0. 147, respectively, Ps ＜ 0. 05 ). The multiple stepwise regression analysis showed that gender( R2 = 0. 161, P ＜ 0. 01 ), ISI ( R2 = 0. 183, P ＜ 0. 01 )and WHR( R2 = 0. 216, P ＜ 0. 01 ) were independent variables associated with Vaspin. Conclusion Serum vaspin level significantly increases in subjects with obesity, and independently associated with gender, ISI,WHR. These findings suggest that serum Vaspin may be involved in the pathophysiology of insulin resistance syndrome.
