Objective To investigate the effect of TanshinoneⅡA on nerve conduction of oxaliplatin induced peripheral neuropathy in rats. Methods Fifty Wistar rats were randomly divided into normal control group, model group, treatment group, prevention group, prevention and treatment group. Except for those in model group, Wistar rats were injected i.p. with oxaliplatin (20 mg/kg). The electrophysiological instrument were employed to detect the sciatic nerve conduction velocity, latency, amplitude 6 h, 24 h, 72 h and 7 d after modeling. Results In the model group, velocity of sciatic nerve conduction slowed, and latency prolonged 24 h after modeling (P<0.05) which continued to slow and prolong until 7 d after modeling (P<0.05). After the application of Tanshinone ⅡA, nerve conduction velocity became faster and latency shorter significantly (P <0.05), especially in the prevention and treatment group, in which no significant difference was found when compared with those in the normal control group (P > 0.05). Conclusions During the chemotherapy with oxaliplatin , TanshinoneⅡA can increase the conduction velocity of sciatic nerve , shorten the disease duration and play a protective role for peripheral nerve.

Objective To study the protective effect and mechanism of lactulose on the renal function in acute cholelithiasis with obstructive jaundice. Methods Fifty five cases of acute cholelithotic obstruction were randomly assigned into lactulose group (group L, n=28) and control group (group C, n=27), and 50% lactulose (group L)or 10% glucose (group C ) was administered orally for 3 days before the operation , respectively. The systemic and portal blood endotoxin (ET), blood urea nitrogen (BUN) and endogenous creatinine clearance rate (Ccr) were measured periodically. Results (1) In group L, the level of systemic vein ET and BUN were significantly lower than that in group C (P0.05); and the systemic vein ET and Ccr decreased significantly on 9d (P

BACKGROUND: In the field of organ transplantation, patients often take immunosuppressants after organ transplantation, such as CsA, FK506, DEX and MPA. However, their mechanisms of immunosuppression are different. The effect of immunosuppressive drugs on monocyte chemoattractant protein-1 (MCP-1) remains poorly understood. OBJECTIVE: To investigate the effects of different immunosuppressants on the secretions of MCP-1 in whole blood. METHODS: The whole blood of healthy volunteers was mixed with different immunosuppressants for 6 hours, such as CsA, FK506, DEX and MPA, which included low, middle and high concentrations, followed by PMA and IONO stimulation for 6 hours. MCP-1 levels in whole blood samples were compared. The whole blood cultured alone served as control. RESULTS AND CONCLUSION: MCP-1 secretion was inhibited by DEX (1, 10 mg/L) and CsA (0.25,1.25 mg/L)- However, FK and MPA exhibited no such effect. Therefore, DEX and CsA may inhibit the function of monocytes and macrophages in immune system by diminishing the secretion of MCP-1. The combination of FK (5 μg/L), MPA (10 mg/L) and DEX (1 mg/L) or CsA (0.25 mg/L), MPA (10 mg/L) and DEX (1 mg/L) can inhibit the secretion of MCP-1, but only DEX among all the immunosuppressants mentioned above exhibited significant effect on inhibiting the secretion of MCP-1 when using alone.

Objective To evaluate the differential expression of lysophosphatidic acid receptor (LPAR) in breast cancer (BC), and its relationship with clinicopathological features of BC patients. Methods The qRT-PCR and immunohistochemical staining were used to detect the LPAR expression in 37 normal tissues, 55 benign disease tissues and 82 BC tissues, besides, the correlation of LPAR expression with clinicopathological data was also analyzed. Results The expression levels of LPAR2 and LPAR3 mRNA and protein in BC tissues were higher than those in normal benign tissues (all P<0.05). LPAR1 mRNA expression had no difference in three tissues (χ2 =1.908, P >0.05). LPAR1 expression was not associated with clinicopathological features in BC tissues (P>0.05). LPAR2 expression in postmenopausal patients was higher than that in premenopausal patients (χ2=4.821, P<0.05). LPAR3 expression was significantly associated with nodal metastasis, estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER2) in BC tissues (all P<0.05). Conclusion LPAR in BC tissues has differential expression, which is associated with nodal metastasis, ER, PR and HER2.

Objective To examine the neural basis of item memory and source memory with fMRI approach.Methods Eight male and eight female healthy fight-handed native Chinese speakers were involved in this study.The item memory and source memory task were conducted with 504 highly frequent Chinese double-character words in the Block-designed experiment.Participants underwent such a double- round procedure as fMRI scanning following study.The fMRI data collected from a GE 1.5T MRI system were analyzed to generate corresponding activation maps for females and males respectively(P20)using statistical parametric mapping software(SPM).Results For females,item memory task activated the bilateral dorsolateral prefrontal cortex(BA6,the number of activated voxel clusters was 62 or 11 in the left and the right,respectively),source memory more activated the left dorsolateral prefrontal cortex(BA6/46,the number was 59).For males,item memory activated the right dorsolateral prefrontal cortex(BA6/46,the number was 64),source memory activated the bilateral dorsolateral prefrontal cortex(BA6,9 and 40 in the left and the right).Conclusion On the neural basis of item or source memory,there exists dissociation,which is that right dorsolateral prefrontal areas are more activated by item memory while left dorsolateral prefrontal areas by source memory.For the difference of gender,it is suggested that left dorsolateral prefrontal areas(BA6/46)are more activated in females while right dorsolateral prefrontal cortex(BA6/46)more in males.
