ABSTRACT
Objective To synthesize a dual-function nanodrug with immunosuppression of tacrolimus (FK506) and lubrication of artificial tear carboxymethylcellulose sodium (CMC), and provide a basis for the clinical treatment of dry eye syndrome. Methods The FK506 nanocrystals were prepared by ultrasonic method, and polyallylamine hydrochloride (PAH) and CMC were deposited alternatively on the surface of FK506 nanocrystals using layer-by-layer (LbL) self-assembly technology to prepare the bifunctional nanodrug. The morphology, particle size, surface charge, and composition of the nanodrug were analyzed. Results The particle size of FK506 nanocrystals was uniform, and the FK506-(PAH/CMC)3 was approximately spherical with uneven surface. Zeta potential detection results showed that the charge changed alternatively with the increasing of layer number. The results of laser scanning confocal imaging and infrared spectroscopy showed that PAH and CMC were successfully modified on the surface of FK506 nanocrystals. Conclusion The prepared FK506-(PAH/CMC)3 nanodrug is expected to provide a scientific basis for the combined treatment of dry eye.

ABSTRACT
Head and neck carcinoma (HNC) is one of the common malignancies in the world. Because of its deep location and complicated surroundings, patients usually receive definitive radiotherapy or concurrent chemoradio-therapy. Early prediction has significant importance to guide physicians in making treatment decisions. Traditional im-aging techniques have obvious limitations. However, positron emission tomography (PET), as a non-invasive functional imaging, allows quantitative assessment of many biologic processes before the anatomic changes, such as proliferation, apoptosis and hypoxia. PET/CT is more and more widely used in HNC nowadays. This article reviewed the advances of clinical application of PET/CT in HNC in this paper
ABSTRACT
Objective To observe the effects of constant light exposure on the obesity in high fat diet rats. Methods Thirty-two male SD rats were randomly divided into four groups:rats on a normal chow exposed to standard light-dark cycle ( group A) , rats on a normal chow exposed to constant light ( group B) , rats on a high fat diet exposed to standard light-dark cycle ( group C) , and rats on a high fat diet exposed to constant light ( group D) . Body weights and food intakes were recorded weekly throughout the 12-week study. Body weight, fat mass, visceral adipose tissue weight, intraperitoneal glucose tolerance test ( IPGTT) results, insulin resistance parameters, serum lipids and levels of interleukin 6 (IL-6), tumor necrosis factor-α(TNF-α) were compared among groups. Epididymal adipose tissues mRNA expression of circadian clock genes, i. e. clock, bmal1, rorα, rev-erbα, cry1, per1, and per2 were analyzed by realtime PCR. Results From the 9th week, body weights of rats in group D were significantly higher than those in group C (all P<0. 05). At the 12th week, area under curve of IPGTT (AUC-IPGTT) in groups B, C, and D were significantly higher than that in group A. AUC-IPGTT in group D was significantly higher than that in group C (all P<0.05). Compared with group C,asignificant increase in fat mass,visceral adipose tissue weight,homeostasis model assessment for insulin resistance, serum cholesterol, TNF-α levels were observed in group D ( all P<0. 05). And a significant decrease in quantitative insulin sensitivity check index ( QUICKI) and high density lipoprotein-cholesterol were observed in group D in comparison with group C (both P<0. 05). Circadian clock genes (clock, rorα, rev-erbα, cry1, per1) mRNA expressions in group B and D were significantly different from those in group A (all P<0. 05) . Expression of cry1 in group D was significantly higher than that in group C. In group C, rev-erbαmRNA expression was significantly down-regulated in comparison with group A (P<0. 05). Conclusion Constant light exposure exaggerates obesity, glycolipid metabolism abnormality, inflammation, and insulin resistance in high fat diet rats.
ABSTRACT
<p><b>OBJECTIVE</b>To assess the association of single nucleotide polymorphisms (SNPs) of NLRP3 gene with metabolic syndrome (MetS).</p><p><b>METHODS</b>A total of 885 subjects including 410 MetS patients and 475 healthy controls were recruited. MetS was defined based on the National Cholesterol Education Program in Adult Treatment Panel III criteria. Two common SNPs of the NLRP3 gene, rs10754558 and rs4612666, were detected using polymerase chain reaction-restriction fragment length polymorphism method.</p><p><b>RESULTS</b>The frequencies of G allele and GG genotype of the NLRP3 rs10754558 in the MetS group were significantly higher than those of the control group. Logistic regression analysis showed that the GG genotype (OR=2.223, 95%CI: 1.296-6.924, P=0.00034) and G allele (OR=1.440, 95%CI: 1.189-4.063, P=0.00028) were associated with increased risk of MetS. NLRP3 rs10754558 GG genotype was associated with higher level of insulin resistance and visceral adiposity index. No association of NLRP3 rs4612666 SNPs with susceptibility to MetS was identified in this population.</p><p><b>CONCLUSION</b>NLRP3 gene rs10754558 polymorphisms are associated with increased risk of MetS. The G allele and genotype GG are risk factors for MetS.</p>

<p><b>OBJECTIVE</b>To investigate the effect of curcumin on oligomer formation and mitochondrial ATP-sensitive potassium channels (mitoKATP) induced by overexpression or mutation of α-synuclein.</p><p><b>METHODS</b>Recombinant plasmids α-synuclein-pEGFP-A53T and α-synuclein-pEGFP-WT were transfected into PC12 cells by lipofectamin method, and intervened by application of curcumin (20 μmol/L) and 5-hydroxydecanoate (5-HD). Oligomer formation in the cultured cells was identified by Western blotting and Dot blotting. Cytotoxicity and apoptosis of the PC12 cells were measured by lactate dehydrogenase (LDH) and JC-1 assays. mitoKATP were identified by Western blotting and whole cell patch clamp.</p><p><b>RESULTS</b>Curcumin has significantly reduced the oligomer formation induced by overexpression or mutation of α-synuclein in the cultured cells. LDH has decreased by 36.3% and 23.5%, and red/green fluorescence ratio of JC-1 was increased respectively by 48.46% and 50.33% after application of curcumin (P<0.05). Protein expression of Kir6.2 has decreased and mitoKATP channel current has significantly increased (P<0.05).</p><p><b>CONCLUSION</b>Curcumin can inhibit α-synuclein gene overexpression or mutation induced α-synuclein oligomers formation. It may block apoptosis induced by wild-type overexpression or mutation of α-synuclein. By stabilizing mitochondrial membrane potential. Opening of mitoKATP channel may have been the initiating protective mechanism of apoptosis induced by wild-type overexpression or mutation of α-synuclein. Curcumin may antagonize above cytotoxicity through further opening the mitoKATP channel.</p>

Conclusion:The optimal determination technology can be applied in the total amino acids from Runing pills,which pro-vides the basis for the further research of Runing pills.
ABSTRACT
Objective To investigate the relationship between a novel polymorphism of C5L2 gene and type 2 diabetes mellitus (T2DM) in Uygur population from Xinjiang region.Methods A novel single nucleotide polymorphism(SNP),698C＞T(P233L) was found using a polymerase chain reaction direct-sequencing method.C5L2 gene 698C ＞ T variant from 252 patients with T2DM and 747 healthy control subjects was detected by polymerase chain reaction and restriction fragment length polymorphism.Result Heterozygote carriers of the 698CT genotype were more frequent among T2DM patients than that among controls (0.107 vs 0.036,x2 =18.576,P＜0.01) in the Uygur population. After adjustment of confounding factors such as sex,age,smoking,alcohol consumption,and hypertension,as well as serum levels of triglyceride,total cholesterol,low-density lipoproteincholesterol,and high-density lipoprotein-cholesterol,the difference remained significant ( P＜0.01,OR =3.373,95％ CI 1.736-6.553 ).Conclusion The CT genotype of the C5L2 gene might be a risk factor of T2DM in Uygur nationality population in Xinjiang.
