Objective To detect the expression of chemoattractant receptors, CXCR4 and formyl peptide receptor (FPR), in rat glioma cell line C6 and to explore their relation to tumor differentiation and angiogenesis. Methods The expression of CXCR4 and FPR by C6 cells were detected with immunocytochemistry. The differentiatial degrees were also detected to analyze the relationship of chemoattractant receptors with angiogenesis and malignancy of glioma. Results C6 cells were of a long spindle shape, expressing high level of vimentin but relatively low level of glial fibrillary acidic protein (GFAP). C6 cells were positive for CXCR4 and FPR in the cytoplasm and strongly positive for vascular endothelial growth factor (VEGF). Conclusion C6 cell line is poorly differentiated and highly expresses chemoattractant receptors CXCR4 and FPR, both of which might be related to the angiogenic potentials.

Objective:To explore the clinical efficacy of Paishi granules on promoting stone expulsion after extracorporeal shock wave lithotripsy ( ESWL) . Methods:A retrospective study method was adopted. Totally 510 cases of lithangiuria patients were divided into the treatment group and the control group with 255 cases in each. The control group was treated by ESWL, and the treatment group was treated by Paishi granules after ESWL. The stone expulsion rate,clinical efficacy and adverse reactions in the two groups were stud-ied and compared. Results:The stone expulsion rate of the observation group was 78. 8%,which was significantly higher than that of the control group (51. 0%, P<0. 05). The curative rate of the observation group was 72. 9% with the total effective rate of 92. 5%, that of the control group was 43. 9% with the total efficiency of 82. 4%,and the differences between the two groups were statistically significant (P<0. 05). There was no statistically significant difference in the incidence of adverse reactions between the two groups (P>0. 05). Conclusion:Using Paishi granules after ESWL can promote stone expulsion with high efficacy and slight adverse reactions.

Objective To observe the effects of saponins of Panax notoginseng (PNS) on the brain energy metabolism and mitochondrial respiratory function of oxidative damaged rat model mimic to Alzheimer disease (AD). Methods Oxidative damaged rat model mimic AD (AD group) was established by injection of dihydroxy fumaric acid (DHF) and FeCl3 ADP into the left lateral ventricle of rats. The contents of adenosine triphosphate (ATP), adenosine diphosphate (ADP), adenosine monophosphate (AMP), and phosphate creatine (Pcr) in brain were determined by high performance liquid chromatography (HPLC). The mitochondrial functions (R3, R4, P/O, and OPR) were observed by Clark oxygen electrode method. The difference in the above parameters in rats in the control group (injection of saline), model group, and administration group (injection of PNS) was observed. Results The levels of ATP, Pcr, and R3, R4, P/O, and OPR of rats in AD group were significantly lower than those in the control group (0.9% NaCl instead of DHF FeCl3 ADP), but those in PNS group were higher than those in the AD group. Conclusion PNS can improve brain energy metabolism and mitochondrial function of oxidative damaged rats, suggesting that PNS could be used for the treatment of AD.

Objective To investigate the protective effects of thalidomide on rats with acute necrotizing pancreatitis (ANP) and its mechanism. Methods Fifty four SD rats were randomly divided into the three groups; ANP group, thalidomide group and control group with 18 rats in each group. The model of ANP was induced by retrograde injection of 5% sodium taurocholate into the bili-pancreatic duct. Rats in thalidomide group received thalidomide 200 mg/kg body weight gastric lavage 1 h after ANP induction. The rats were sacrificed 3 h, 6 h, and 12 h after ANP induction, and the amount of intraperitoneal ascites was quantified. The serum levels of TNF-α, IL-6, IL-18 were measured by EUSA. The proportion of CD4 + T cell, CD8 + T cell in peripheral blood was determined by flow cytometry. The expression of TNF-α mRNA in pancreatic tissue were measured by RT-PCR. The expression of ICAM-1 protein in pancreatic tissue was measured by immunohistochemistry. Pancreatic tissue underwent pathologic examination. Results Six hours after surgery, the amount of ascite, serum levels of TNF-α, IL-6, IL-18, CD4 + T cell, CD,+ T cell, pancreatic TNF-α mRNA and ICAM-1 protein expression, pathologic score in control group was (1.03 ±0.31)ml,(57.17±11.29)pg/ml, (24.45 ±4.14)pg/ml, (64.23 ±21.85)pg/ml, (47.58 ±9.21)% , (40.88 ± 2.96)%, 0.07 ±0.02, 0.57 ±0.30, 0.67 ±0.81, respectively, and the corresponding values were (3.63 ± 0.38)ml, (107.54 ±33.05) pg/ml, (47.30 ± 11.40) pg/ml, (367.76 ± 108.43 ) pg/ml, (54.90 ± 7.15)%, (17.17 ±3.12)%, 0.65 ±0.26, 3.20 ±0.57, 11.50 ±1.87 in ANP group; and (1.45 ±0.53)ml, (80.60 ±20.48) pg/ml, (26.61 ±10.85) pg/ml, (321.82 ±85.20) pg/ml, (29.80 ±2.19)% , (15.52± 1.96)%, 0.35 ±0.23, 2.37 ±0.67, 8.00 ±3.03. Besides the value of CD8 + T cell was significantly decreased, all other values were significantly increased when compared with control group (P <0.05). Conclusions Thalidomide can decrease the release of inflammatory mediator, and reduce the pathological damage of pancreas of ANP rats by inhibiting TNF-α mRNA expression.

Objective To determine the effects of Hyperoside ( Hyp) on the memory impairment induced by hypobaric hypoxia. Meth-ods SD rats were exposed in hypobaric hypoxia chamber which simulated 6 100 m high altitude for 7 days to induce memory impairment. Morris maze was applied to determine the effects of Hyp on memory in hypobaric chamber. The activities of SOD and CAT and levels of GSH and MDA in rat hippocampus were measured by assay kit ( Nanjing Jiancheng Bioengineering Institute) . Results In target quadrant,the time and path and the frequency to cross platform were reduced under hypobaric hypoxia as compared with normoxia group ( P < 0. 05 or P<0. 01). Administration of Hyp significantly attenuated the hypoxia-induced the memory impairment responses(P<0. 05 or P<0. 01). The activities of SOD and CAT in rats hippocampus exposed to hypobaric hypoxia were significantly improved in the presence of Hyp as com-pared with the absence of Hyp(P<0. 05 or P<0. 01),so did GSH level (P<0. 05 or P<0. 01). Significant decrease of MDA levels was observed in the hippocampus on exposure to hypobaric hypoxia with Hyp as compared without Hyp. Conclusion Hyp reduces hypoxia-in-duced oxidative stress injury by upregulating activity of antioxidant proteins such as SOD,CAT in hippocampus of rats, which contribute to at-tenuate memory impairment induced by hypobaric hypoxia.
