OBJECTIVE:To evaluate therapuetic efficacy and toxic reaction of 2 therapuetic regimens for 56 cases of bone me-tastasis of cervical cancer. METHODS:56 cases of bone metastasis of cervical cancer with complete information were collected ret-rospectively and randomly divided into radiochemotherapy group(31 cases)and diphosphonate group(25 cases). Radiochemothera-py group was given radiotherapy,chemotherapy and diphosphonate;diphosphonate group was given palliative symptomatic treat-ment of diphosphonate;a treatment course lasted for 3-4 weeks,and both groups received 3 courses of treatment. Average survival time,survival quality and toxic reaction were comparison in 2 groups. RESULTS:After bone metastasis of cervical cancer,the av-erage survival time of radiochemotherapy group was 17 months (95%CI:9.1-24.9),and that of diphosphonate group was 19 months (95%CI:2.4-35.6);3 years later,the survival rate of radiochemotherapy group was 16.1%,and that of diphosphonate group was 16.0%,there was no statistical significance(P=0.820). To compared KPS after 3 treatment courses,the improvement rate of radiochemotherapy group(22.6%)was significantly lower than that of diphosphonate group(40.0%),with statistical signif-icance (χ2=4.36,P<0.05). Toxic reaction of radiochemotherapy group was more significant than that of diphosphonate group. CONCLUSIONS:Diphosphonate has little effect on survial quality and slight toxic reaction. It is worthy of spreading in some pa-tients with advanced,elderly and reccurred bone metastasis of cervical cancer.

Objective To investigate the relationship between human epidermal growth factor receptor 2 (HER-2) gene amplification, the expression of HER-2 protein and the clinical characteristics in invasive breast cancer. Methods 105 patients with invasive breast cancer were examined by immunohistochemistry (IHC) and fluorescence in situ hybridization (FISH). The correlation between expression of HER-2 protein and the gene amplification of HER-2 was compared, and their relationship with clinicopathologic features was analyzed. Results 105 patients with invasive breast cancer included 35 cases of HER-2 gene amplification. The coincidence rates of HER-2 protein 0 and + (negative), ++ (uncertainty),+++ (positive) and FISH detection of HER-2 gene amplification were 94.5 % (17/18), 23.5 % (16/68) and 94.7 % (18/19) respectively. HER-2 gene amplification was associated with estrogen receptor, progesterone receptor expression and lymph node metastasis (all P< 0.05), but not with age and tumor differentiation (P>0.05). Conclusions The prognosis of invasive breast cancer is correlated with the amplification of HER-2 gene. Patients with HER-2 protein negative and positive can be selectively confirmed by FISH; patients with HER-2 protein uncertainty should routinely use FISH to detect HER-2 gene amplification status, which could provide data for the clinical treatment and prognosis judgement.

Considering a variety of theories such like Dunkin's, Centra's and Kolitch's, a set of 13 indicators are designed to evaluate effect of courses taken in high education of China currently, compro-mised by chief aspects of course designing, practicing, and effect. Three courses including medical nursing, humanistic cultivation and communication skills in nursing and fundamentals of nursing in a nursing de-partment are chosen to be objects of questionnaire survey about the above indicators. The results show that there are significant differences in curriculum effectiveness between different courses. The scores are 2.81, 2.80 and 2.60 respectively, and teachers and students have different evaluation on the same indicators of the same curriculum,which provides a reference for teachers, colleges and universities and teaching management departments to promote the improvement of teaching quality.

Objective To evaluate the potential effects of RS504393, CC chemokine receptor (CCR) 2b and CCR1 antagonist, on LPS-induced acute lung injury (ALI) and to investigate the underlying mechanisms. Method A549 cell line was stimulated with LPS (10 μg/mL) and then treated with RS504393 (10 μg/mL) for 6 hours. ALI model was established with intranasal administration of LPS (5 mg/kg) in C57BL/6J mice. RS504393 (5 mg/kg) was administered 30 min before LPS dripped nasally. IL-8, IL-1β, plasminogen activator inhibitor (PAI)-l,monocyte chemoattractant protein (MCP)-2,and the expressions of CCR1 and CCR2b were studied by using Realtime-RT-PCR, ELISA and cyto-flowmetry. Results In A549 cell line treated with RS504393,the expressions of CCR1, CCR2b and IL-8 were significantly inhibited after LPS stimulation. In rats with LPS-induced ALI, treatment with RS504393 significantly protected mice against lung injury by attenuating influx of leukocytes and protein into bronchoalveolar space and by lessening pathological changes of lung. Treatment with RS504393 down-regulated IL-1β and PAI-1 expressions in bronchoal veolar lavage fluid (BALF) and lungs at mRNA and protein levels along with up-regulation MCP-2 expression compared to rats of vehicle-treated groups. Conclusions CCR2b and CCR1 play pivotal roles in the development of ALl,and RS504393 as a antagonist can halt the development of ALI.
