Objective:To detect and compare the intensity of gingipain K(Kgp)in culture medium and cell extract of Porphyromonas gingivalis(P.gingivalis)isolates in puberty gingivitis,and then to reveal the possible relationship between Kgp and puberty gingivitis.Methods:36 patients with puberty gingivitis aged from 14 to 17 years were enrolled.Clinical parameters including GI,SBI and PD were evaluated before subgingival plaque samples collection.Subgingival plaque samples were collected and then P.gingivalis isolates were obtained.16S rRNA PCR was used to confirm the presence of P.gingivalis in clinical isolates.Bacteria were cultured in BHI agar base and harvested at the end of log-phase growth.Culture fractions of P.gingivalis(culture medium and cell extracts)were performed with SDS-PAGE and Western blot technique using primary antibody against specific anti-Kgp N-terminal IgG subdomain.The data were statistically analyzed using SPSS 11.5 software.The relationship between the Kgp intensity and the clinical parameters was statistically analyzed using sum rank test.Results:There was positive correlation between the intensity of Kgp N-terminal IgG subdomain and the clinical parameters(P

Objective To investigate the prevalence of urticaria among children aged 2-6 years in Nanjing city.Methods A questionnaire survey was carried out in children aged 2-6 years in 5 main districts of Nanjing City.Results The number of valid questionnaires was 13 610,accounting for 92.8％ of total respondents.Among the 13 610 respondents,1 116 were diagnosed as urticaria,including 565 boys and 551 girls,with the total prevalence rate being 8.54％.No significant difference was observed in the prevalence rate of urticaria between boys and girls (8.49％ vs.8.60％,x2 =0.04,P =0.832) or among children of different age groups (x2 =1.84,P =0.17).The prevalence of urticaria increased with age,and positively correlated with parents' educational level (rs =0.96,P =0.000).Children born in urban areas showed higher prevalence of urticaria than those in rural areas (8.79％ vs.5.56％,x2 =13.98,P =0.000).Conclusions The prevalence of urticaria has increased among children aged 2-6 years in recent years.More studies should be carried out to investigate into the pathogenesis and relevant factors of urticaria,so as to facilitate its prevention and treatment.

Objective:To investigate the relationship between college freshman adaptation and adverse childhood events,and to explore the mediating role of personality characteristics.Methods:A sample of 523 college freshmen from a key university in Sichuan Province was assessed with the China College Student Adjustment Scale (CCSAS),Adverse Childhood Events Questionnaire (ACEQ) and Eysenck Personality Questionnaire-Revised,Short Scale for Chinese(EPQ-RSC).Results:The rate of adverse childhood events of college freshmen was 87％ in current study.The total scores of adaptation were negatively correlated with the scores of adverse childhood events influence and neuroticism (r ＝-0.13,-0.51,Ps ＜ 0.01),while positively correlated with introversion-extroversion and lie (r ＝ 0.47,0.25,Ps ＜ 0.01).The scores of adverse childhood events influence were negatively correlated with scores of introversion-extroversion (r ＝-0.08,P ＜0.05) and lie (r ＝-0.12,P ＜0.01),while positively correlated with scores of neuroticism (r ＝ 0.17,P ＜ 0.01).Introversion-extroversion and neuroticism mediated the relationship between adverse childhood events influence and college freshman adaptation,the mediating effects were 51.65％ and 58.10％.Conclusion:College freshman adaptation may be closely associated with adverse childhood events influence and personality characteristics.Personality characteristics may play a mediating role between adverse childhood events influence and adaptation in college freshman.

Aim To study the effect of ZD7288 on synaptic transmission in the pathway from perforant pathway (PP) fibers to CA3 region in rat hippocampus. Methods The extracellular recording technique in vivo was used to record the CA3 region field potentials. High-performance liquid chromatography (HPLC) with fluorescence detection was applied to measure the content of amino acids in hippocampal tissues. The effect of ZD7288 and CsCl on the amplitudes of population spike (PS) in CA3 region evoked by stimulation (0.5 Hz) of the perforant pathway (PP) fibers, and the content of amino acids in hippocampal tissue were observed. Results Microinjection of ZD7288 (20, 100 and 200 nmol)and CsCl (1,5 and 10 μmol) into CA3 region decreased the population spike (PS) amplitudes in a dosedependent manner. The inhibitory effects appeared at 5 min after microinjection and lasted at least 90 min.In those rats treated with ZD7288 (100 nmol), the contents of glutamate, aspartate, glycine and GABA decreased significantly as compared to those of saline control ( all P＜0.01, except P＜0.05 for that of glycine). A similar decrease in the contents of amino acids was observed when the rats were microinjected with CsCl (5 μmol). Conclusion ZD7288 could obviously inhibit synaptic transmission in the pathway from PP fibers to CA3 region in rat hippocampus, and this action of ZD7288 may be associated with altered contents of amino acids.

Objective To determine normal reference values for conduction in the posterior antebrachial cutaneous nerve.Methods Antidromic sensory conduction examinations of the bilateral posterior antebrachial cutaneous nerve were conducted with fifty-eight healthy subjects.The onset latency,peak latency,peak-to-peak amplitude and conduction velocity of the sensory nerve action potentials (SNAPs) were recorded and the inter-side ratios of the peak-to-peak amplitudes were calculated.Results The observed means (and standard deviations) of the onset time,the peak latency,the amplitude and the conduction velocity were 1.96 (0.12) ms,2.48 (0.14) ms,7.39 (2.36) μV and 61.39 (3.69) m/s,respectively.The side-to-side amplitude ratio (smaller/larger) was 0.88 ± 0.09,and no significant difference was observed between the left and right side.The average peak latency and amplitude were significantly different for different age groups.There was no statistically significant difference among the age groups with regard to onset latency or conduction velocity.Conclusion Conduction in the posterior antebrachial cutaneous nerve is easy to study.The peak latency is prolonged and the amplitude decreases with age,suggesting that different normal reference values should be established for different age groups.

Objective To estimate the test-retest reliability of limits of stability (LOS) measurement in healthy young adults. MethodsTwenty-five healthy young adults participated this study.Their center of pressure (COP) displacements were recorded while they stood on a force platform.The subjects performed maximal voluntary sway maneuvers in the anterior,posterior,left and right directions in turn.The LOS in each direction was calculated using balance clinic software.Each subject underwent 3 consecutive,identical tests at 7 day intervals with the same investigator.The test-retest reliability of LOS was analyzed using the intraclass correlation coefficient (ICC).ResultsFor the first test the ICC values ( ICC1 ) of the LOS ranged from 0.790 to 0.857.For the mean LOS of the first two tests the ICC2 ranged from 0.906 to 0.937,and for the mean LOS of three tests the ICC3 ranged from 0.910 to 0.948. ConclusionThe LOS test is a reliable measurement with healthy young adults.In clinical practice,averaging two LOS tests is suggested in assessing balance and postural control with young adults.

Among 172 patients with coronary artery disease (CAD),94 received community and hospital joint management (joint group) after percutaneous coronary intervention (PCI) for Ⅰ year and 78 received community-based health education only (control group) after PCI.The compliance of medication,readmission rate,times of hospitalization,medical costs,major adverse cardiac events (MACE),and general quality of life inventory (CQOLI-74),self-rating anxiety scale (SAS) and self-rating depression scale (SDS) scores were compared between two groups.The rate of readmission,times of hospitalization,medical costs,the sores of SAS and SDS in joint group were lower than those in control group(P ＜ 0.01 or 0.05).The compliance of medication,body health dimension,psychological health dimension and social function dimension in joint group were better than those in control group,but there were no differences in material life dimension and the MACE rate between two groups(P ＞ 0.05).Community and hospital joint management can reduce the readmission rate and medical burden,and improve quality of life for elderly CAD patients after PCI.

Objective To assess the influence of community and hospital comprehensive Health management on quality of life in aged patients with coronary artery disease (CAD) after PCI.Methods 147 patients with CAD after PCI were divided into experimental group(72 cases) and control group (75 cases) accordance with their residential community.In control group,community health education was introduced.While in experimental group,hospital and community comprehensive healthy education lasted for one year.Before and after invention,major adverse cardiac events (MACE) was recorded and generic quality of life inventory (CQOLI-74),self-rating anxiety scale (SAS),and self-rating depression scale (SDS) were carried out on the basis of giving unite guiding words.Results The observation items of the SAS(34±6 vs41 ±7,t =2.714,P ＜0.01)and SDS(35 ±7 vs 41 ±8,t =2.572,P ＜0.05)scores in experimental group were lower than those in control group.Meanwhile the body health dimension(63 ± 12 vs 59 ±11,t =5.935,P ＜0.01 ),psychological health dimension(64 ± 14 vs 58 ± 13,t =6.116,P ＜0.01 ),social function dimension(64 ± 11 vs 58 ± 10,t =6.157,P ＜0.01 ) were higher than those in control group,but the difference of the material life dimension and the MACE rate were not statistically significant( P ＞0.05).Conclusions Community and Hospital comprehensive health management is a practical and valuable strategy for palliating the depression and anxiety and improving quality of life after PCI in aged patients.
