Objective: To study the effect of different ratios of n-6 to n-3 polyunsaturated fatty acid on serum lipid in mice, on the premise that the ratio of SFA to MUFA to PUFA is 1∶1.7∶1.2 or 1∶1∶1. Methods: Ten experimental diets were made from six oils different in fatty acid composition to raise the mice for 10 w. Then the blood lipids were determined in mice fed with different experimental diets. Results and conclusion: Based on the ratio of S/M/P 1∶1.7∶1.2, which is the current dietary fatty acid intake, n-6/n-3 at 1~5∶1 will have lower serum lipid level. Based on the ratio of S/M/P 1∶1∶1 , n-6/n-3 at 1∶1 will have lower serum lipid level. Based on the ratio of n-6 /n-3 10∶1 which is the current dietary fatty acid composition abroad , S/M/P 1∶1.7∶1.2 will have lower serum lipid level.

The study is aimed to confirm the silencing efficiency of the vector in human hepatocellular liver carcinoma cell line (HepG2), and observe effects of AMPKgamma silencing on the AMPK stimulating activity and lipid synthesis of cordycepin (CCS), a natural product with known AMPK activating function. The downregulating efficacy of siRNAs on AMPKgamma expression was confirmed in our previous study. The double stranded shRNA Oligo was ligated to lentivirus vector and verified by sequencing. The lentiviral which can effectively inhibited protein expression levels of AMPKgamma was selected by Western blotting, and the regulation of CCS on protein expression of AMPKgamma and p-AMPK in AMPKgamma silence cells were detected by Western blotting analysis. The lipid accumulation in cells was observed by Oil-Red O stain and cells were collected for the estimation of cholesterol (TC), triglyceride (TG). The results showed that the lentiviral vector carrying a shRNA targeting the AMPKgamma gene was successfully constructed. Western blotting analysis confirmed that GR085 had the highest interfering efficiency. Treatment with CCS can significantly increase the levels of phospho-AMPK in normal cells, and the level of TC, TG was reduced, but in AMPKgamma silence cells the effects of CCS on AMPK activation and lipid synthesis were almost completely abolished without changing the expression levels of total AMPK or AMPKgamma protein. In conclusion, the AMPKgamma gene may be related to AMPK activation and intracellular lipids regulation by CCS.

Objective To investigate the imaging features of adrenal rest tumor.Methods Twelve patients of adrenal rest tumor proved by surgery or clinical diagnosis were retrospectively analyzed.Among these 12 patients,12 were examined with ultrasound,11 with MR and 1 with CT. MR and CT were performed without and with intravenous injection of contrast material.The imaging features of adrenal rest tumor were retrospectively summarized and the relevant literatures reviewed. Results The adrenal rest tumors were found in testis in 10 of the 12 patients,and in ovaries and broad ligament in the remaining two.The imaging features of the testicular adrenal rest tumor were summarized as following:all patients had bilateral testicular masses without change of the testicular contour. On ultrasonography,the lesions were hypoechoic, with some hyperechoic areas and appeared highly vascularized on Colour Doppler ultrasonography.The masses showed iso-density on plain CT,and avid enhancement on post-contrast CT images.The masses ranging in size from0.7 cm×1.0 cm×2.2 cm to 2.3 cm ×2.7 cm ×2.9 cm with uniform signal intensity,lobulated margin on MRI.They exhibited iso- or slight hyperintensity on T1 WI and hypointensity on T2WI relative to normal testicular parenchyma.The tumors showed intense enhancement on post-contrast MR images. No abnormality was detected with Colour Doppler uhrasonography and MR in 2 patients of adrenal rest tumor in ovaries and broad ligament. Conclusion Combining imaging features with the typical clinical history,the diagnosis of adrenal rest tumor could be suggested pre-operatively.

Objective To analyze the differences in the levels of serum adiponectin between premature neonates.and term neonates.To explore the effect of preterm on the level of serum adiponoctin and the mechanism by which prcterm contributes with the serious risk factor of type 2 diabetes and cardiovascular diseases in adulthood.Method The serum adiponectin concentration was quan-tified in 30 term neonates and 21 premature neonates hy immunoradiometric assay.Results The concentration of serum adiponeetin was (34.29?7.24) mg/L in premature neonates and(62.47?28.33) mg/L in term neonates. The level of serum adiponetin in pre-mature neonates was significantly lower than that in term neonates ( P

Multi-component traditional Chinese medicines are an innovative research mode for traditional Chinese medicines. Currently, there are many design methods for developing multi-component traditional Chinese medicines, but their common feature is the lack of effective connection of the traditional Chinese medicine theory. In this paper, the authors discussed the multi-component traditional Chinese medicine design methods based on medicinal property combination modes, provided the combination methods with the characteristics of traditional Chinese medicine for the prescription combinations, and proved its feasibly with hypertension cases.
