Objective To explore whether the inflammatory stress can increase insulin resistance in the CD36 knockout (KO) mice.Methods After the mice were fed a standard chow for 14 weeks,oral glucose tolerance test,insulin release tests,lipids metabolism,SAA,IL-6,TNF-? and hepatic mRNA and proteins expression of mTOR,S6K,IRS-1,pIRS-1,2 were measured.Results Compared with the wide-type,the CD36 KO mice un-inflamed exhibited insulin resistance,and the insulin resistance index was increased[(3.01?1.24) vs (0.81?0.12),P

Excess energy has become a main reason for increasingly serious human health hazards. Excess energy, mainly ectopically deposits in the liver, pancreas and other organs in the form of triglycerides, and produces chronic oxidative, nitrosative stress (ONS) , and fat toxicity, resulting in insulin resistance and impaired insulin secretion, and further impaired glucose regulation (Pidan). By combining Chinese medical pathogeneses and symptoms analyses, authors found this process has features of Gan disease transferring to Pi. Based on a number of related guidelines and clinical practice, we demonstrated treating sputum and stasis by the same method was one treatment method for intervening liver disease transferring to spleen in metabolic diseases. This idea helps to organic integrating prevention and treatment of major metabolic diseases including non-alcoholic fatty liver disease (NAFLD) and type 2 diabetes mellitus, which can improve clinical effectiveness and efficiency of Chinese medicine.

Objectives To observe the changes of magnetic resonance imaging(MRI) during the course of treatment in hepatolen-ticular degeneration (HLD) and to evaluate its related factors.Methods Sixty - three patients with HLD received routine SE sequence MRI of brain and liver.Twenty - two patients with abnormal MRI in 42 patients and each of them had 2-4 times of serial MRI ex-aminations at interval of 1.0- 1.5 year.Results Ten patients had lesion in both brain and liver in 22 patients. Nine patients only in brain, 3 patients in liver.The major lesions disappear or decrease after rational treatments. There were only slight or no changes of MRI abnormalities in patients receiving treatments or age of patients was over 15 year old. Abnormal MRI findings shown again after stopped treatments over 2 months. In such cases, the clinical and MRI improvements were slow.The rate of clinical and MRI improvement in patients with adequate treatment were markedly higher than patients with inadequate treatment.Conclusions Liver and brain lesion will show in MRI disappear after adequate treatment;There are only slight or no change or showing again in MRI abnormalities in pa-tients with inadequate treatments compared with poor clinical improvement. MRI is beneficial to understanding therapeutic effect and prognosis of HLD.

The penetrating technique of acupuncture from Yemen (TE 2) to Zhongzhu (TE 3) acts on the extraordinary effect of promoting Shaoyang meridian qi. The technique is specially good for heat pattern/syndrome of the triple energizer and it is commonly used in the treatment of common cold, high fever, anhidrosis in heat pattern/syndrome, migraine, redness, swelling and pain of the eye, tinnitus, ear pain, swelling and pain of the teeth, ulcers in the mouth and tongue, sore throat, neck rigidity, etc. In the manipulation, the needle is inserted from Yemen (TE 2), going obliquely upward along the metacarpal interspace to Zhongzhu (TE 3). With this technique, the Ying-spring and Shu-stream acupoints can be stimulated simultaneously with one needle. This method is characterized as less acupoints, exquisite needling, strong sensation, easy and safe manipulation, remarkable immediate effect and high curative rate of single treatment. Hence, it is worthy of application in clinical practice.

Objective To analyze the substitutions at amino acid residues of neuraminidases ( NAs) in influenza B virus strains isolated in Jiangsu province from 2010 to 2012 and to further understand the genetic evolution of NAs in those influenza B virus strains .Methods Forty strains of influenza B virus isolated in Jiangsu province from 2010 to 2012 were screened out for this study .A two-step reverse transcrip-tion PCR ( RT-PCR) was performed to amply the gene fragments encoding the neuraminidases of influenza B virus strains.The PCR products were purified and then sequenced in an ABI 3730XL Genetic Analyzer.The evolutionary characteristics of NA gene were analyzed by using DNAStar , Bioedit, MEGA 5.0 and BEAST 1.8.0 softwares.Results The phylogenetic tree analysis of the NA genes showed that the NAs of 28 Vic-toria strains were derived from the Yamagata lineage .There were reassortments between the Victoria lineage-HA and theYamagata lineage-NA.Some of the strains added a glycosylation site at position 462.No substitu-tion was found in important enzyme active sites and neuraminidase inhibitor resistant sites .The Bayesian MCMC analysis showed that the estimated mean evolutionary rate for NA gene was 1.74×10-3(95%HPD:1.46×10-3-2.06×10-3) substitutions/site/year.The dN/dS ratio (ω), an indicator of selective pressure, was 0.24.Conclusion The important amino acid sites of NA were relatively conservative and the evolution -ary rate for NA gene was low .The dN/dS ratio was less than one , indicating that the NA gene was under pu-rifying selection .

1.6 kb ?4-desaturase gene(FAD4)was amplified by PCR using plasmid pGEM-TFAD4 as template.The fragment was subcloned into the HindⅢ/XbaⅠrestriction site of pYES2.0 vector.Recombinant plasmid pYFAD4 was transformed into Saccharomyces cerevisiae strain INVScl for expression.It was found to exhibit ?4-fatty acid desaturase activity in the recombinant S.cerevisiae YFAD4 in the presence of exogenous fatty acid substrate docosapentaenoic acid(100?mol/L)under introduction of GAL1.Expression of the FAD4 under appropriate media and temperature conditions led to the production of DHA and it reached 41.13% of the total yeast fatty acid by GC detection.It was suggested that the protein encoded by FAD4 could specifically catalyze DPA into DHA.

BackgroundBiological behavior of choroidal melanoma is closely related with angiogenesis.The microcirculation pattern in which tumor cells may be involved is different from neovascularization.ObjectiveThis study was to observe the microcirculation pattern of the choroidal melanoma tissue and analyze its relationship with the clinical pathology factor and the degree of cellular proliferation.Methods Forty-eight specimen of choroidal melanoma tissue were collected at Beijing Tongren Eye Centre from November 1997 through March 2006.Periodate acid Schiff staining was used to determine the microcirculation pattern of choroidal melanoma.The morphology of the tumor cells and the distribution of microcirculation pattern in the tumor were observed under a fluorescence microscopy with 544 nm wavelength,and the Ki-67 expression in the tumor was detected by immunochemistry.The relationships between the choroidal melanoma clinical pathology factor with Ki-67 expression and microcirculation pattern were evaluated by multiple stepwise regression model.ResultsA total of 9 kinds of microcirculation patterns were found by periodate acid Schiff staining.The occurring rate of loop- or network-like vascular pattern showed a significant elevation in the tumor tissue with epithelial cells in comparison with the tumor with spindle-like cells (66.7％ vs.30.6％ ) ( P=0.027 ).The expression rates of Ki-67 were 18.961 ± 10.995 and 19.481 ± 12.167 in the tumor tissue with loop- or network-like microvascular pattern,and those in the tumor tissue without loop- or network-like microvascular pattern were 10.261 ±5.669 and 12.021 ± 6.802,presenting significant differences between them ( P =0.000,P =0.010).Loop-like microvascular pattern was determined as the risk factor of the proliferation and metastasis of choroidal melanoma by multiple stepwise regression analysis (P=0.002).ConclusionsAmong the nine microcirculation patterns in choroidal melanoma,networks pattern is the most fashion,and Ki-67 expression is more strong in the tumor with epitheliod cells,suggesting that this microcirculation pattern is associated to the malignant degree and extent of proliferation in choroidal melanoma.
