We standardized nurses' qualification and training requirements, and performed management in patients'symptom assessment, nursingtechniqueguidance for breast cancer, sleep guidance, health education, long-term follow up, etc. After one year of implementation, symptom assessment was conducted 1283 times, rehabilitationexerciseguidance was 329 times, lymphatic drainage guidance was 297 times, sleep guidance was 159 times, health education was 591 times, sexual life with spouse guidance was 107 times, in-hospital nursing consultation was 48 times, family on-site demonstration was 29 times. The satis-faction rate was 98.4% which was higher than average level of the hospital according to outpatient investigation.

950 mg/d) group was significantly higher than those in median or low calcium intake group,among girls with BB genotype. However,such significant effect was not detected among girls with b allele. Conclusion:The PTH BstBⅠ polymorphism has significant interaction effect with calcium intake on bone mass accretion in Chinese adolescent girls. High calcium intake would be beneficial to gain higher bone mass accretion for girls with BB genotype than those with b allele.

Aim The protective effect and mechanism of TPG on PC12 cells in calcium overloading injury models were studied. Methods Two injury models induced by KCl and NMDA were used to assay the action of TPG in cultured PC12 cells. Results The morphological examination revealed that TPG possessed obvious protective effects on PC12 cells in injury models. MTT and LDH measurement indicated that TPG increased the number of live cells and reduced the extent of cell injury significantly. TPG also lessened the concentration of calcium ion in cytoplasm. Conclusion TPG protected rat PC12 cells against two calcium overloading injuries effectively in vitro. Its actions may deal with anti oxidation, inhibition of NO production and blocking of both types of calcium channel.

Objective To study clinical features of liver damage in primary Sj(o)gren syndrome (pSS) and its related factors.Methods One hundred and forty-nine patients of confirmed pSS hospitalized at Peking University People's Hospital were analyzed retrospectively.Results Seventeen of 149 patients of pSS (11.4%) showed liver damage,10 diagnosed as autoimmune hepatitis and seven as primary biliary liver cirrhosis.Increased serum levels of IgG,IgM and γ-globulin accounted for 88.2% and 50.8%,35.3% and 5.3%,and 94.1% and 47.7% of those complicated with and without liver damage,respectively,with statistically significant difference (P ＜ 0.05).Positive serum anti-mitochondria antibody subtype M2 (AMA-M2) was 35.3% in pSS patients with liver damage,significantly higher than that in those without liver damage (1.5%) (P ＜ 0.05).Independent risk factors significantly associated with liver damage included age (OR = 1.013,95% CI 0.971-1.058),course of illness (OR = 1.089,95% CI 1.032-1.150),serum level of γ-globulin (OR = 4.021,95% CI 1.246-12.982),positive AMA-M2 (OR = 11.82,95% CI 0.005-0.157),and positive anti-SSA (OR = 101.333,95% CI 12.653-811.560).Conclusions Liver damage occurred rather high in pSS patients and increased serum levels of IgG,IgM,γ-globulin and anti-SSA can be used to predict their complication with liver damage.Age,course of illness,serum level of γ-globulin,positive AMA-M2 and positive anti-SSA are all significantly associated with liver damage in pSS patients.

Objective: The bacterial superantigen staphylococcal enterotoxin A (SEA) has the potent ability of inducing T cell activation as well as directing activated T cells to kill tumour cells. However, its application in the tumour treatment is limited due to its systemic immune activation.In order to minimize its side effects SEA liposomes is prepared and their toxcicity in vivo is investigated . Methods: SEA liposomes were prepared by the method of reverse-phase evaporation . SEA liposomes were administered intravenously . In vivo the toxcicity of SEA liposomes was investigated by the measurement of blood pressure, colonic temperature and breath rate of New Zealand rabbits. Mice plasma TNF-? and IFN-? level were determined by ELISA . Results:After iv administration of SEA liposomes, significant reduction of mice plasma TNF-? and IFN-? level was observerd. As compared to free SEA, liposomal SEA had less effect on blood pressure, colonic temperature and breath rate of the rabbits. Conclusion:SEA Liposomes had relatively low toxicity. These advantage was probably due to its lower systemic immune activation effect and inducing consequent lower systemic TNF-? and IFN-? level.

Objective To observe the effect of severe heatstroke on intestinal mucosal barrier function,and explore its correlation with systemic inflammatory reaction.Methods The SPF male BALB/c mice were randomly divided into normal control group,40 ℃ heat stress group and 42 ℃ heat stress group,with 6 mice in each group.The mice in normal control group were observed at normal temperature with (25.0 ± 0.5)℃,and the mice in heat stress groups were challenged with a temperature of (35.5 ± 0.5) ℃ and a humidity of (60 ± 5)％ until body temperature increase up to 40 ℃ or 42 ℃ followed by recovering the surroundings temperature to normal temperature for 12 hours.The blood of medial angle of eye of mice in each group was collected for determination of plasma lipopolysaccharide (LPS),tumor necrosis factor-α (TNF-α),interleukin-6 (IL-6) levels,and diamine oxidase (DAO) activity with enzyme linked immunosorbent assay (ELISA).The level of D-lactic acid was determined with ultraviolet spectrophotometer.Then the mice in each group were sacrificed,and mesenteric lymph node (MLN),liver,spleen,lung,kidney tissues,and the blood from portal vein and caval vein were collected for colony count to observe the intestinal bacterial translocation.The ileum tissue was collected for observation of changes in histomorphology and ultrastructure of small intestine mucous membrane with microscope.Pearson linear regression analysis was used to explore the correlation between intestinal mucosal barrier dysfunction and systemic inflammatory response.Results Compared with normal control group,plasma LPS,inflammatory parameters such as TNF-α and IL-6,and gut barrier function parameters such as DAO and D-lactic acid levels as well as the rate of bacterial translocation after heat stress were significantly increased,and the differences were more obvious in 42 ℃ heat stress group [LPS (EU/L):740±50 vs.340±40,TNF-α (ng/L):148.06±36.61 vs.12.89 ± 1.67,IL-6 (ng/L):110.91 ± 9.97 vs.18.02 ± 2.20,DAO (U/L):1 760 ± 400 vs.670± 50,D-lactic acid (mg/L):9.60 ± 1.48 vs.5.08 ± 0.28,rate of bacterial translocation:78.6％ (33/42) vs.9.5％ (4/42),all P ＜ 0.01].It was shown by Pearson linear regression analysis that plasma LPS,TNF-α,IL-6 were positively correlated with DAO activity (r values were 0.834,0.808,0.836,respectively) and D-lactic acid (r values were 0.811,0.811,0.800,respectively) in 42 ℃ heat stress group (all P =0.000).It was showed by microscope that the changes in histomorphology and ultrastructure changes in intestinal mucosa were found after heat stress,and was obvious in 42 ℃ heat stress group as following:villus atrophy and falling off,infiltration of neutrophils and lymphocytes,the microvillus on the surface of mucosa cells were short and small,arranged in disorder,the tight junction between epithelial cells became widen,the mitochondrion and endoplasmic reticulum swelled obviously.Conclusion During the early stage of severe heatstroke,the damage of intestinal mucosal was obvious,and it has close correlation with systemic inflammatory response.

BACKGROUND: It has been confirmed that some casting alloy can inhibit the activity of human gingival fibroblasts in vitro, which can be used for inducing apoptosis of human gingival fibroblasts (HGFs). However, the mechanism of this effect is poorly understood.OBJECTIVE: To investigate the effect of Ni-Cr, Co-Cr, Au and pure Ti ceramic alloys on the expression of P70S6k by HGFs in vitro.DESIGN, TIME AND SETTING: Grouping controlled experiments with the expression of P70s6k by HGFs in each group as observation objects. Experiments were performed at the Institute of Immunohistochemistry and Western blotting, Technology Building of Liaoning Medical University from July to October 2009.MATERIALS: Ni-Cr, Co-Cr, Au and pure Ti ceramic alloys were processed by Shenzhen Mecodent Dental Laboratory Co., Ltd. The gingival from gingival neck of the first premolar (which goes to be extracted due to the need of orthodontic treatment) of teenager who was15 years old without any clinical disease was obtained, followed by the primary culture of HGFs. The fifth passage of cells in logarithmic phase were used to measure indexes.METHODS: Ni-Cr, Co-Cr, Au and pure Ti ceramic alloys were incubated in DMEM to prepare alloy leaching liquor, which were then added in HGF medium at 10% concentration. DMEM containing 10% fetal bovine serum was used in negative controls. MAIN OUTCOME MEASURES: The expression of P70S6k in each group was measured by Western Blotting following 72 hours of intervention with alloy leaching liquor.RESULTS: Western-blot results showed that there was no significant difference in the average gray value of P70S6k expression in Au, pure Ti ceramic alloys and control groups (P > 0.05). There was also no significant difference between Au ceramic alloys and pure Ti ceramic alloys groups or between Ni-Cr ceramic alloys and Co-Cr ceramic alloys groups. (P > 0.05), but Ni-Cr ceramic alloys group or Co-Cr ceramic alloys group showed significant difference compared with the Au, pure Ti ceramic alloys and control groups (P < 0.01).CONCLUSION: Au ceramic alloys and pure Ti ceramic alloys show that they have no obvious effect on the proliferation activity of HGFs. Ni-Cr and Co-Cr ceramic alloys showed an inhibitory effect on the proliferation activity of HGFs.

Objective:To investigate the immunogenicity of pORF5 plasmid protein,and further to screen and identify its im-munodominant domian.Methods: 10 different fragments of pORF5 gene including full length were amplified from the DNA of Chlamydia trachomatis serovar D by PCR and cloned into appropriate site of pGEX-6p vector to construct recombinant vectors after digested with BamHⅠand NotⅠrestriction endonucleases.After identification by PCR and sequencing,the recombinant plasmids were transformed into XL1 Blue E.coli to express the GST fusion proteins.ELISA and Western blot were carried out to identify the immunogenicity and immunoreaction of pORF5 plasmid protein.10 different fragments were reacted with sera from patients urogenitally infected with Chlamydia trachomatis, mouse polyclonal antibodies and mouse monoclonal antibodies of pORF5 plasmid protein with ELISA method.Results: pORF5 plasmid protein displayed strong immunogenicity and could induce a strong antibody response in human.The reactivity of human antibodies almost completely disappeared,when the native structure of pORF5 plasmid protein was de-stroyed.F6 that only lacked the N-terminal 66 amino acids was recognized by antibodies in ELISA as strongly as the whole pORF5 plasmid protein was.However,no other fragments were significantly recognized although there was a minimal reactivity of F2 and F3 with antibodies.Conclusion:pORF5 plasmid protein was an immunodominant antigen containing conformation-dependent epitope,and the C-terminal three quarters of pORF5 amino acid sequence was required for maintaining its immune dominance and conformation.The significance of the above findings lay a foundation for the further study on pORF5 protein function and vaccine development.
