The free radical scavenging effect of flaxseed was screened by HPLC-DPPH ( 2 , 2-diphenyl-1-picrylhydrazyl-high performance liquid chromatography assay ) and colorimetric DPPH methods. To test the effectiveness of the approach, three Lignans ( secoisolariciresinol diglucoside ( SDG ) , secoisolariciresinol ( SECO) and enterodiol( ED) ) with antioxidative properties were investigated both in monomer and mixture. HPLC conditions were optimized using following methods: Waters XBridge C18 was used as stationary phase, acetonil/H2 O was used as mobile phase and detective wavelength was set at 280 nm. Antioxidant activity of standards was investigated by reaction with or without DPPH radical for 20 min as sample and control, respectively. Both of them were analyzed by high performance liquid chromatography. According to the changes of amount of sample and control, the antioxidant activities of standards were calculated as following order:SDG>SECO>ED. Based on above DPPH-HPLC assay and UPLC-Q-TOF-MS, antioxidants extracted from flaxseed were separated, identified and screened. The radical scavenging activities were in the following order:SDG isomer (5)>SDG (4)>7α-[(β-D-glupyranosyl) oxy]-1-methoxyisolariciresinol (1)>(6R,7R, 8S)-1-methoxyisolariciresinol (2)>herbacetindiglucoside (3). It indicated that the HPLC-DPPH assay could be successfully used for the antioxidant activity screening of complex flaxseed extract.

The levels of triglyceride(TG)and free fatty acid(FFA)in serum,liver,skeletal muscle,and pancreas of lipoprotein lipase gene knockout heterozygous(LPL+/-)mice and C57 mice were determined.Intraperitoneal glucose tolerance test(IPGTT)was performed to evaluate insulin sensitivity and β-cell function.The results showed that the Iipid content in 16 weeks LPL+/- group did not increase significantly.The TG and FFA contents in 28 weeks LPL+/- group were significantly higher than those in control and 16 weeks LPL+/-group(all P<0.05).In 50 weeks LPL+/- group,FFA levels in serum and pancreas,and TG content in pancreas increased significantly compared with other three groups(all P<0.05).The IPGTT result showed that the blood glucose levels increased from 15 to 120 min,not at 0 and 5 min.The blood glucose levels during 30-120 min increased significantly in 50 weeks LPL+/- group compared with other three groups(P<0.05).Fasting insulin(FINS),homoestasis assessment of insulin resistance(HOMA-IR)and pancreatic β cell function also increased gradually with age.FINS and HOMA-IR in 28 weeks LPL+/- group were higher than those in control and 16 weeks LPL+/- group.These results suggest that LPL is a key enzyme in lipid metabolism and plays a crucial role in the development of insulin resistance and diabetes.

Objective To investigate the expression of a proliferation-inducing ligand (APRIL) in urothelial carcinoma tissue and its clinical significance. Methods We investigated the expression of APRIL mR-NA in urothelial carcinoma tissue of 33 patients in urothelial carcinoma in Cangzhou Central Hospital from July 2013 to March 2015, Among of them, 23 cases of adjacent pericancerous tissues were detected by qRT-PCR. Immunohistochemistry and western blot were used to detect the APRIL protein expression level in urothelial carci-noma tissue and adjacent pericancerous tissues. We analyzed the relationship between APRIL expression and clinical pathology in patients with urothelial carcinoma by statistical methods. Results The qRT-PCR revealed that the expression of APRIL in urothelial carcinoma tissue was significantly higher than that in the adjacent peri-cancerous tissues (P < 0.05). Immunohistochemistry and western blot showed that the expression of APRIL in urothelial carcinoma tissue was higher than that in the adjacent pericancerous tissues. Correlation analysis found that the high expression of APRIL in urothelial carcinoma tissue was not significantly related to gender , age , size of tumor, lymph node metastasizing or not, and clinical stages (P > 0.05). Conclusion The APRIL is a high abnormal expression in urothelial carcinoma tissues , and maybe related to the occurrence and development of urothelial carcinoma.

Objective:To detect the expression of Shank1 protein in renal cell carcinoma (RCC), to investigate its difference between the tumor and carcinoma adjacent tissue, and to analyze its correlation with RCC clinicopathological characteristics and prognosis. Methods:The renal carcinoma and carcinoma adjacent tissues of 120 patients were selected from Cangzhou Central Hospital and Ji'nan Central Hospital from May 2008 to December 2014. The expression level of Shank1 was determined by immunohistochemistry and Western blot. Statistical analysis was performed to determine the relationship between the expression of Shank1 and the clinicopathological features of RCC patients. Results:Results of immunohistochemistry showed that the expression level of Shank1 in renal cancer tissue was significantly higher than that in carcinoma adjacent tissue, and the difference was statistically significant (P<0.05). Western blot results showed that the expression level of Shank1 protein in renal cancer tissue was also significantly higher than in carcinoma adjacent tissue. Correlation analysis found that the high expression level of Shank1 in renal cancer tissue was not significantly related to gender, age, tumor size, and TNM stage, but was significantly associated with the histological differentiation of RCC (P<0.05). Conclusion:Shank1 is abnormal y expressed in RCC renal cancer tissues and is correlated with the histological differentiation of RCC.

OBJECTIVEThe present study was undertaken to design antisense oligodeoxynucleotides (AS-ODNs) of glial glutamate transporter-la (GLT-1a) and to evaluate the effectiveness of the designed AS-ODNs on the expression of GLT-1a.

METHODSFive sequences of GLT-1a AS-ODNs were designed according to the C terminus specific sequences of GLT-1a mRNA using antisense design software of IDT Com- pany. Western blot analysis was used to evaluate the inhibition effects of the five GLT-1a AS-ODNs on the expression of GLT-la.

RESULTSThe sequence of GLT-1a AS-ODNs with sequence of 5'-GGTTCTTCCTCAACACTGCA-3' could specifically inhibit the expression of GLT-1a in the hippocampal CA1 subfield of rats, while it had no effect on the expression of GLT-1b. This sequence showed similar inhibition on the expression of GLT-la in sham and ceftriaxone (Cef)-treated rats. It could also significantly inhibit the cerebral ischemic preconditioning (CIP)-induced up-regulation in the expression of GLT-1a. The magnitude of the inhibition in sham, Cef- or CIP-treated rats was similar by more than 60%.

CONCLUSIONFrom the designed five sequences of GLT-1a AS-ODNs, we obtained an effective sequence which can specifically inhibit the expression of GLT-1a.

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.
