Objective To retrospectivly analyze the value of Pap smear,liquid-based cells, colposcopy and colposcopic cervical biopsy in the diagnosis of cervical cancer. Methods 116 cases of cervical cancer were retrospectively analyzed, and the value of Pap smear,liquid-based cells ,colposcopy,and colposcopic cervical biopsy in the diagnosis of cervical cancer were investigated. Result 116 patients were pathologically diagnosed with cervical cancer before and after surgery. Pap smear was performed for 30 patients (25.9%) ,and 10 patients (33.3%) were detected with HSIL. Liquid-based cells was performed for47 patients (40.5%) ,and 25 patients (53.1%) were detected with HSIL. Colposcopy was performed for 99 patients (85.3%), and 75 patients (75.8 % ) were detected with HSIL or invasive cancer. Preoperative colposcopic biopsy was performed for 99 patients, and the pathological coincidence rate was 94.9%. There was no significant difference statistically between two cytology screening ( P ＞ 0.05 ). There was significant difference statistically between liquid-based cells and colposcopy ( P ＜ 0.01 ). There were significant differences statistically among liquid-based cells,colposcopy ,and colposcopic cervical biopsy ( P ＜0.01 ). Conclusion Cytology, colposcopy, colposcopic cervical biopsy could not be individually more complete and accurate detection of cervical cancer. Colposcopy,colposcopic biopsy than cytology had higher accurate rate of diagnosis of cervical cancer. A reasonable combination of multiple detection methods could improve the diagnostic accuracy of cervical cancer.

Objective To explore the effects of lycopene on interleukin-6 (IL-6) expression and motor function after spinal cord injury in rats. Methods 36 healthy adult Sprague-Dawley rats were randomly divided into control group (A), methylprednisolone sodium succinate (MP) treatment group (B) and lycopene treatment group (C) with 12 rats in each group, and spinal cord injury model at T9 was established with modified Allen's technique (10 g×25 mm). 30 minutes after modeling, group A received no treatment, group B was injected MP 30 mg/ kg, group C was given lycopene 20 mg/kg. They were tested with inclined plate test 1 day, 3 days and 7 days after injury. The expression of IL-6 was examined with immunohistochemistry, then. Results The inclined plate test scores were higher in the group C than in the group A 1 day and 7 days after injury (P<0.05), and in the group B than in the group A 1 day, 3 days and 7 days after injury (P<0.05). The expression of IL-6 was significantly lower in the groups B and C than in the group A 1 day, 3 days, 7 days after injury (P<0.001). Conclusion Lycopene can inhibit the expression of IL-6 in acute spinal cord injury to reduce the inflammation and facilitate the recovery of nerve and motor function.

AIM To testify the special cytotoxicity of TGF? SAP on proliferating vascular smooth muscle cells and endothelial cells. METHODS Conjugation of saporin to TGF? was accomplished after derivatization of saporin and TGF? with N succinimidyl 3 (2 pyridyldithio) proprionate. Cytotoxicity assays were measured by cell count. The studies of influence of TGF? SAP on values of thymidine and leucine incorporation into SMCs and ECs were measured by 3H thymidine uptake and 3H leucine uptake, respectively. RESULTS Cytotoxicity assays testified TGF? SAP conjugate could inhibit remarkably proliferation of SMCs in culture. The values of thymidine of TGF? SAP group (1?10 -9 mol?L -1 and 1?10 -7 mol?L -1 ) in comparison significantly decreased to 60 9% and 56 0% of the control group respectively, suggesting that cellular DNA synthesis obviously decreased as TGF? SAP was added. But saporin did not affect cellular DNA synthesis at higher level. The rate of 3H leucine incorporation of TGF? SAP group significantly decreased to 47 3% of the control group, suggesting that SMCs protein synthesis obviously decreased as TGF? SAP was added. But TGF? SAP at the same level did not affect DNA synthesis and protein synthesis of ECs compared with the control group. CONCLUSION TGF? SAP possesses the more effective cytotoxicity than saporin and the more specific citotoxicity on proliferating vascular smooth muscle cells than on proliferating endothelial cells.

T cell immunoglobulin and mucin domain 3 (Tim-3) is well known to negatively regulate T cells responses, but its role in burn-induced T cells immune suppression remains unclear. In the present study, in order to identify the relationship between Tim-3 expression and post-burn T cells immune suppression, C57BL/6 mice were subjected to burn injury or sham injury, and the liver and spleen were harvested at the day 1 after operation. The expression level of Tim-3 on hepatic or splenic T cells and the functional properties of Tim-3(+) T cells were evaluated. It was found burn injury induced dramatically elevated Tim-3 expression on both hepatic and splenic CD4(+) and CD8(+) T cells in contrast with the post-burn depletion of T cells. Furthermore, Tim-3 expression was correlated with the suppressive phenotype of T cells following burn injury, including increased expression of anti-inflammatory cytokine IL-10, decreased expression of pro-inflammatory cytokines IFN-γ and TNF-α, reduced T cell proliferation and elevated co-expression of Tim-3 and PD-1. Moreover, Tim-3(+) T cells subsets were more prone to spontaneous apoptosis than Tim-3(-) T cells subsets. Our findings reinforce the idea that the up-regulated expression of Tim-3 on T cells after burn injury plays an important role in the development and maintenance of burn-induced T cell immune suppression.

Objective To investigate the role of phosphatidylinositol 3-kinase (PI3K)/protein-serine-threonine kinases(Akt) signal transduction pathway in EphB receptor-mediated neuropathic pain in rats.Methods Forty-eight pathogen-free male SD rats aged 2-3 months weighing 150-180 g were randomly divided into 6 groups (n =8 each):groups sham operation (groups S1 and S2 ); groups chronic constrictive injury (CCI) (groups C1and C2 ) and groups EphBI-Fc (EphB receptor antagonist) + CCI (groups E1 and E2 ).Neuropathic pain was induced by placing 4 ligatures on left sciatic nerve at 1 mm intervals with 5-0 silk thread in groups C1,C2,E1 and E2.EphBI-Fc 0.5 μg in 5 μl normal saline was injected intrathecally 1 h before operation and at 1 and 2 d after operation (group E1 ) or on 5th day after operation (group E2).Normal saline 5 μl was injected intrathecally instead of EphBI-Fc 1 h before operation and at 1 and 2 days after operation (groups S1 and C1 ) or on 5th day after operation (groups S2 and C2 ).Pain withdrawal latency to noxious thermal stimulation (PWL) and pain withdrawal threshold to noxious mechanical stimulation (PWT) were measured before operation and at 1,3 and 5 d after operation.The animals were sacrificed at 5 d after operation after measurement of pain threshold.The lumbar segment of spinal cord (L4-6) was removed for determination of c-Fos,PI3K and phosphorylated Akt(p-Akt) expression.Results CCI significantly reduced PWL and PWT and up-regulated spinal c-Fos,PI3K and p-Akt expression in groups C1 and C2 as compared with groups S1 and S2.EphB1-Fc significantly decreased hyperalgesia and the upregulated spinal Fos,PI3K and p-Akt protein expression induced by CCI in groups E1 and E2 as compared with groups C1 and C2.Conclusion Spinal EphB receptor is involved in the development and maintenance of neuropathic pain through PI3K/Akt signal transduction pathway.

A total of 1342 individuals underwent physical examinations according to the criteria of metabolic syndrome of International Diabetes Federation (IDF) in 2005.And 314 patients with metabolic disorders were screened for diabetes by standard meal and methods oral glucose tolerance test (OGTT).Newly diagnosed diabetics was 12 (4.1％ ) vs.17 (5.8％) respectively.No significant difference existed between two methods (P =0.332).Kendall's (τ)b =0.313,Kendall's (τ)c =0.208 and Gamma coefficient =0.580 (P =0.000).The mixed meal method was correlated with OGTT,Kappa =0.258 (P =0.000) and two methods were consistent.Diabetic screening should be stressed in the subjects with metabolic abnormalities.And the detecting efficiency of postprandial plasma glucose is similar to OGTT.
