Objective To explore the protective effect of rhG-CSF given intranasally on cerebral infarct rats by observing the neurological dysfunction and the expression of Fas ligand (FasL) in hippocampus of cerebral infarct rats.Methods Middle cerebral artery occlusion(MCAO) model rats were established by nylon strand,reperfuse 2 hours later,and give rhG-CSF through subcutaneous and intranasal way.The rats were divided into the nermal group,the sham-operated control group(sham),MCAO group,MCAO+NS given intranasally group(NS),MCAO + rhG-CSF given subcutaneously group,and MCAO + rhG-CSF given intranasally group each group had 6 rats. At the time of 3d after reperfusion,neurological severity scores (NSS) test was performed and the expression of FasL was detected via immunohistochemical staining in collateral hippocampus. Results Neurological dysfunction appeared in all groups except for the normal and the sham group. The dysfunction of the MCAO and the NS group was the most serious,the NSS was the highest(10.20±1.85,10.30±1.76),the number of FasL positive cells was the most(41.17±3.25,41.00±2.76),and there was no obvious difference between the two groups ( P >0.05);the NSS and FasL positive cells decreased in the subcutaneous group(5.67±1.32,P <0.01;32.67±1.97,P <0.01) and decreased further more in the intranasal group(4.00±0.93,P <0.05;19.50±1.05,P <0.01).Conclusions rhG-CSF given intranasally can relieve the neurological dysfunction of cerebral infarct rats,and brain cells are thereby protected by resisting the expression of FasL.

Purpose:To study the expression and clinical significance of PTEN in non-small cell lung cancer. Methods:Immunohistochemical staining was used to determine the expression of PTEN in 10 cases of normal lung issues and 56 cases of non-small cell lung cancer. Results:The positive incidences of PTEN expression in NSCLC was 59% while positive expression was found in all normal lung issues. The expression of PTEN was correlated to degree of differention of cancer, lymph node metastasis and clinical stages. The PTEN negative group was seen to have the worst survival rate among all groups. Conclusions:The results suggest that PTEN gene plays an important role in carcinogenesis and progress of NSCLC. Expression of PTEN may be valuable in prognosis assessment of NSCLC.

Objective To investigate and explore the awareness and willingness of breast cancer screening between Han and Mongolian women in Ordos, Inner Mongolia Autonomous Region, and to analyze the influence factors. Methods The patients answered investigation questionnaires face to face, and the content of questionnaire included demographic information, breast cancer awareness and relevant affecting factors on the awareness and willingness. Results 11162 (88.2 %) Han women and 1495 (11.8 %) Mongolian women were enrolled in the survey, with the average age of (45.4 ±7.1) years old and (45.4 ±6.8) years old. The education level (high school and above) of Han women was lower than that of Mongolian women [4456 women (40.0%) vs. 750 women (50.2%), χ2= 57.041, P< 0.001]. The Main way to delivery information on breast cancer screening in Han and Mongolian women was from their family members or friends [5002 women (44.9%) vs. 688 women (46.1%),χ2=40.699, P<0.001]. The proportions of never attending screening in the Han and Mongolian women were 41.7 % (4640 women) and 45.9 % (683 women), respectively (χ2=14.075, P=0.001). The breast self-examination rate of Han women were higher than that of Mongolian [71.1 % (7926 women) vs. 58.5 % (872 women), χ2= 98.466, P< 0.001]. According to logistics regression analysis, the cognitive level of women with high education level and breast disease history was higher (all P<0.001). Conclusions The cognitive level of breast cancer screening in Han women is better than that in the Mongolian, however, the overall level are low. It is necessary to strengthen the propaganda and education, and to encourage women to actively participate in breast cancer screening.

OBJECTIVETo investigate the effect of gradually induced disordered occlusion (GIDO) on the expression of osteoprotegerin (OPG) and receptor activator of nuclear factor-kappaB ligand (RANKL) in mandibular condylar cartilage of rats.
METHODSTotally 48 rats, aged 8 weeks were included, and were divided into experimental and control groups randomly at 4 time points, with same gender distribution (n=3). By inserting elastic rubber band the right side mandibular first molar and the left side maxillary first molar were moved mesially. Four weeks later, the right side mandibular third molar and the left side maxillary third molar were moved distally with same method. In this way, the GIDO was established in rats. The rats were sacrificed at the end of 2th, 4th, 6th and 8th week respectively after the application of the GIDO. The expression of OPG and RANKL in condylar cartilage was examined with immunohistochemical method and calculated by the area of positive cell percentage.
RESULTSOPG and RANKL expressed predominantly in condylar cartilage hypertrophic layer. The rats in experimental group expressed a higher OPG level in all of the 4 time points than their age-matched controls (P<0.05), while RANKL were higher in 2, 6, 8 weeks subgroups (P<0.05), but not in 4 weeks subgroup. No differences were found between male and female subgroups.
CONCLUSIONThe present results suggest that both OPG and RANKL take part in the condylar cartilage remodeling procedure in the present rat model.

Dendritic cell-based cancer vaccines (DC vaccines) have been proved efficient and safe in immunotherapy of various cancers, including melanoma, ovarian and prostate cancer. However, the clinical responses were not always satisfied. Here we proposed a novel strategy to prepare DC vaccines. In the present study, a fusion protein SNU containing a secretin-penetratin (SecPen) peptide, NY-ESO-1 and ubiquitin was designed and expressed. To establish the DC vaccine (DC-SNU), the mouse bone marrow-derived DCs (BMDCs) were isolated, pulsed with SNU and maturated with cytokine cocktail. Then peripheral blood mononuclear cells (PBMCs) from C57BL/6 mice inoculated intraperitoneally with DC-SNU were separated and cocultured with MC38/MC38
