ObjectiveTo investigate the related things of community nurse post training, so that training can be carried out accordingly. Methods160 trainees of Suining and Neijiang in 2009 were investigated anonymously with self-designed questionnaire. ResultsTrainees mainly came from the 1st and.2nd grade public hospitals and community health service centers. 68.7％ of trainees were engaged in clinical nursing in hospitals before training, and 51.5％ trainees went in for community nursing after the training. Trainees were generally clear about the category, related knowledge and skill requirements of community nursing. ConclusionThe present post training time is relatively short. Continuing education of community nursing and exploration on training model of community nursing specialists are suggested.

Objective To investigate the effect of Cimetidine on the adhesion between colorectal cancer LOVO cells and endothelial ECV304 cells;and study whether Cimetidine can inhibit the expression of E-selectin in ECV304 cells. Methods Cellular uptake of rose Bengal stain was used to measure the adhesion between LOVO cells and ECV304 cells. Enzyme-linked immunosorbent assay(ELISA)and flow cytometry (FCM, indirect fluorescence staining and labeling)were used to detect the expression of E-selectin. Results ECV304 cells were exposed to different concentrations of Cimetidine. Both the adhesion between LOVO cells and ECV304 cells and the levels of E-selectin significantly decreased with increasing concentration of Cimetidine(P =0. 001 and 0. 001 respectively). Conclusion Cimetidine can inhibit the adhesion of human colorectal cancer LOVO cells on endothelial ECV304 cells by blocking E-selectin expression. Our observations indicated a potential of anti-adhesion therapy using Cimetidine in cancer treatment.

Objective To investigate the acoustic characteristics of snoring sound in patients with obstructive sleep apnea hypopnea syndrome (OSAHS) and with simple snoring. Methods 22 patients with OSAHS and 15 with simple snoring were included in this study. Natural overnight snoring was digitally recorded and portable sleep mo-nitoring was performed simultaneously. 10 snores, which were the 1st snores after 10 cycles of obstructive apnea, from each patient in OSAHS group, and 10 snores from each patient in simple snoring group were analyzed in the time and frequency domains. Results The sound waves of snoring in the two groups exhibited different patterns both in the time and frequency domains. The snoring spectrum of patients with simple snoring showed distinct fun-damental- harmonic structures which were not clear in patients with OSAHS. The central frequency of the patients with OSAHS was higher, and 800 Hz power ratio was lower than those of the patients with simple snoring. In the OSAHS group, the central frequency of the patients with moderate-to-severe OSAHS was higher, and 800 Hz power ratio was lower than those of the patients with mild OSAHS. The differences of the two parameters were of statistical significance. Conclusion The snoring sounds in patients with OSAHS and with simple snoring have dif-ferent characteristics in time and frequency domains, indicating that it is feasible to research the OSAHS by way of snore monitoring and analyzing technique.

Objective To set up the molecular cytobiological model of endogenous coagulation factor Ⅷ (FⅧ) re-expressing in human liver cells L02,and to study the regulation pathway and molecular basis of the re-expression of FⅧ in L02 cells activated by NO signal.Methods The L02 cells at logarithm growth phase were selected and randomly divided into blank control group and experimental group, inhibitor group and inhibitor control group;they were cultured for 0,12,24,36,48,and 60 h.Flow cytometry was used to detect the expression of human FⅧ protein in L02 cells after treated for 48 h.Griess experiment was performed to detect the levels of NO in L02 cells at different time points;the transcription levels of human FⅧ gene,iNOS gene,NF-κB1 gene and I-κB alpha gene were detected by RT-PCR method.Western blotting method was used to detect the expression levels of human phosphorylated I-kappaB (phosphorylated I-κB)in L02 cells.Results The results of flow cytometry showed that the expression of human L02 FⅧ protein was found after treated with L-arginine for 48 h. The Griess results showed that the levels of NO in L02 cells in experimental group were significantly increased at 3,6,12,and 24 h (P<0.05)and the levels of NO in blank control group,inhibitor group and inhibitor control group had no changes. The RT-PCR results showed that the transcription of human FⅧ mRNA in L02 cells was found in experimental group,but there was no transcription of human FⅧ mRNA in blank control group,inhibitor group and inhibitor control group;the transcription levels of iNOS,NF-κB1 and I-κB alphain experiment group were increased(P<0.05)and the transcription levels of these genes in blank control group,inhibitor group and inhibitor control group had no changes. The Western blotting results showed that after adding L-arginine the expression level of phosphorylated I-κB was significantly increased (P < 0.05 ), other groups had no such change. Conclusion L-arginine can activate the phosphorylation of I-κB by NO signal pathway to lead to the changes in the expression of human FⅧ gene promoter upstream regulatory-related transcription factors NF-κB to activate the expression of human FⅧ in human liver cells L02.

OBJECTIVE: To discuss the main influence factors of sound pressure level parameters in patients with simple snoring (SS) and obstructive sleep apnea hypopnea syndrom (OSAHS). METHOD: Eighty-four cases with snoring disease underwent polysomnography and simultaneously snoring sound pressure level recording. The correlations between AHI, age, BMI, abdomen circumference, neck circumference, the lowest oxygen saturation total apnea time and sound pressure level parameters: equivalent continuous sound level(LAeq)and maximum sound pressure level(L10) were analyzed. RESULT: LAeq was significantly correlated to AHI (P= 0. 000) and BMI (P= 0. 007), and the odd ratios of AHI and BMI were 5. 74,2. 09 respectively, but it was unrelated to age, abdomen circumference, neck circumference, the lowest oxygen saturation and total apnea time. A significantly association also existed between L10 and AHI(P=0. 000), BMI(P=0. 032), and the odd ratios were 4. 11 and 2. 33 respectively. Other factors had nothing to do with L10. CONCLUSION The main factors which affect the snoring sound pressure level parameters LAeq and L10 are AHI and BMI.

Objective To investigate the effects of fragile X mental retardation protein（FMRP）on the development and migration of cerebellar neurons in mouse model.Methods Plasmids containing FMRPmutant-EGFP or EGFP were established and transfected into the lateral ventricle of the embryo mouse.Fragile X syndrome（FXS）genotype of the mouse model was identified.Nissl staining and immunofluorescence staining were conducted to assess the changes in neuron development and migration.Results In the experimental group,Nissl staining showed that the deep cerebellar neuclei contracted and divided by white matter,and the non-polarized Purkinje cells retained in internal granular layer;while immunofluorescence staining showed that Tbr2-positive unipolar brush cells changed the migration pathway and accumulated in the ventricular zone.Conclusion Cerebellar neurons showed abnormal formation and migration with the absence of FMRP.
