Objective To examine the serum high-sensitivity C-reactive protein(hs-CRP)levels in subjects with type 2 diabetic mellitus(DM)or DM accompanied by cerebral infarction(DM+CI),and the relationship be- tween the serum high-sensitivity C-reactive protein(hs-CRP)levels,and to investigate risk factors of cerebral infarc- tion in patients with type 2 diabetic mellitus.Methods The serum high-sensitivity C-reactive protein(hs-CRP)lev- els were measured in 50 DM patients,50 DM+CI patients and 30 healthy controls by ultra-sensitive immunoassay. hs-CRP values and its relationship with cerebral infarction in patients with type 2 diabetic mellitus and other factors, such as age,BMI,TG,etc,were analyzed.Results Univariate analysis revealed significant differences in hs-CRP concentrations between controls[(0.73?0.46)mg/L]and subjects with DM[(2.26?1.38)mg/L],or subjects with DM+CI[(3.82?2.67)mg/L](P

Objective To investigate the expression of Yes‐associated protein(YAP) in human papillary thyroid cancer and its influence on cell growth .Methods The samples in 57 cases of papillary thyroid cancer treated by operation resection in the gen‐eral surgery department of this hospital and the matched tumor‐adjacent tissues were collected .All the cases were definitely diag‐nosed by the pathology examination .The expression of YAP protein in the cancer tissue and corresponding tumor‐adjacent tissue were determined by the immunohistochemistry(IHC)staining .The relationship between the YAP protein and the clinicopathological data was statistically analyzed .siRNA was used to silence the expression of YAP in B‐CPAP cells ,MTT and flow cytometry were used to measure the proliferation and apoptosis changes .Results The expression level of YAP was markedly higher in papillary thyroid cancer tissues than in tumor adjacent tissues (P<0 .05);moreover the expression of YAP protein was positively correlated with the tumor size and TNM stage (P<0 .05) .Silencing YAP gene could significantly inhibit the cell proliferation ability and pro‐mote cell apoptosis(P<0 .05) .Conclusion YAP is highly expressed in papillary thyroid cancer tissues and is related with its ad‐verse clinicopathological characteristics ,down‐regulating YAP gene can significantly inhibit the cell growth .

The ubiquitin-proteasome pathway is one of important pathways during selective protein degradation,which participates in many intracellular physiological and biochemical processes.Bortezomib,a kind of proteasome inhibitor,can inhibit cell growth and proliferation,induce cell apoptosis and overcome drug resistance in chemotherapy.The mechanisms of bortezomib on the therapy of multiple myeloma are reviewed in this paper.

The tuberous roots of Aconitum carmichaeli are largely used in traditional Chinese medicine and widely grown in Jiangyou, Sichuan, China. During the growth process, this medicinal plant releases a large amount of allelochemicals into soil, which retard the growth and development of near and late crops. Therefore, a pure culture experiment was thus carried out by seed soaking to study the allelopathic effects of extracts from tuberous roots of A. carmichaeli (ETR) on the seed germination and young seedling growth of Lolium perenne, Trifolium repens, and Medicago sativa, the late pasture grasses after cultivation of A. carmichaeli. The results showed that three pasture grasses varied significantly in seed germination and young seedling growth in response to ETR concentrations. Seed germination of M. sativa was stimulated by low ERT concentration (0.01 x g(-1)), while all of pasture grass seeds germinated poorly in solution with 1.00 g x L(-1). Seed soaking with 1.00 g x L(-1) also inhibited significantly the growth of pasture young seedlings, with M. sativa showing the highest seedling height reduction of 42.05% in seeding height, followed by T. repens (40.21%) and L. perenne with about 11%. Cultivation of L. perenne could thus be beneficial to increase whole land productivity in A. carmichaeli-pasture grass cropping systems. In addition, hydrolysis of protein, starch, and inositol phosphates was blocked and free amino acids, soluble sugars and phosphorus were decreased in seeds by seed soaking with ETR, which could be one of the reason for the inhibition of seed germination. There was a significant reduction in root vigor, nitrate reductase, and chlorophyll after the seed treatment with ETR, indicating the suppression of nutrient uptake, nitrate assimilation, and photosynthesis by allelopathic chemicals in ETR, which could lead to the slow growth rate of pasture grass seedlings.
