Objective To investigate the ability in the activities of daily living (ADL) of children with hemophilia and the factors which influence it.Methods Sixty boys aged 4-12 years with hemophilia were recruited.Their ADL ability was assessed using the functional independence score in hemophilia (FISH).Results The average FISH score of the sixty patients was 25.75 ± 5.71.The percentage of the patients who had experienced functional declines in self-care,transfer and locomotion abilities were 46.7％,55％ and 75％,respectively.There was negative correlation between the patients＇ ages,the replacement therapy they had received and their FISH scores.The Spearman correlation coefficients were-0.371 and-0.388 respectively.The duration and frequency of the preventive therapy and appropriate exercise they had experienced were positively correlated with their FISH scores.The Spearman coefficients were 0.339.0.317 and 0.436 respectively.But there was no correlation between FISH scores and the level of coagulating factor in the subjects＇ blood,their frequency of bleeding in the most recent three months,muscle bleeding,the dosage of replacement therapy or the patient＇s place of residence.Conclusion Seventy-five percent of young,male hemophilia patients manifest a decline in ADL ability.Declines in locomotion occurred the most frequently.The ADL ability of young hemophilia patients probably declines with age.Long term preventive therapy and appropriate exercise would be helpful to maintain ADL ability.

The basic nursing quality is an important dial of the general administration level and the basic personnel quality of a hospital.Many causes have led to the down trend of the basic nursing quali- ty.After a specific analysis of the causes of such a trend,important measures and solutions have been put forth,The first is to strengthen the moral education of the profession and upgrade the quality of the nursing staff.The second is to adopt the "group responsibility" administration and gradually carry out a systimatic integrated nursing so that a transformation of nursing models is put to practice,The third is to broaden the outlet of human resources so that personnel are rationally employed and the rate of job— taking raised.The last one is to heighten the initiative of the nursing staff through the rational opera- tion of the "incentive"mechanism in accordance with the law of values.

Objective To investigate the clinical significance of the changes of hypersensitive C-reactive protein (hs-CRP) and myocardial enzyme spectrum,cardiac troponin Ⅰ (cTn Ⅰ) in patients with Henoch-Schnlein purpura.Methods 100 patients with Henoch-Schnlein purpura were selected.50 patients only skin involved were selected as the simple group,50 patients accompanied by other organs involved were selected as mixed group.50 healthy people in the same period were selected as the control group.The serum hs-CRP,myocardial enzyme spectrum and cTn Ⅰ were tested and compared.Results The hs-CRP,serum myocardial enzyme spectrum and cTn Ⅰ levels of mixed and simple group were significantly higher than the control group(all P ＜ 0.05) ; Serum CK-MB,cTn Ⅰ and hs-CRP levels of the mixed group were significantly higher than those of simple group (all P ＜ 0.05).The abnormalities number of CK-MB and cTn Ⅰ respectively accounted for 33％ (33/100) and 32％ (32/100) ;The constituent ratio of the number of abnormal serum CK-MB and cTn Ⅰ of the mixed group was significantly higher than the simple group (x2 =4.047,3.908,all P ＜ 0.05) ;The Pearson correlation analysis showed that the relationship between the serum hs-CRP and CK-MB,cTn Ⅰ levels was linear,which were positively correlated (r =0.872,0.801,all P ＜ 0.05).Conclusion Patients with allergic purpura should early detect the serum levels of hs-CRP,myocardial enzyme spectrum and cTn Ⅰ,and treat the myocardial injury in time.

BACKGROUND:Children teeth filed with glass ionomer cement are stil susceptible with secondary caries, which is in close relationship with complex microbial community in dental plaque on the surface of glass ionomer cement. Traditional microbial methods are incapable of getting important information towards dental plaque microbes. OBJECTIVE:To analyze microbial community structure and numerical level of caries-induced microbes in dental plaque on the surface of glass ionomer cement for different caries-susceptible children. METHODS:Twenty-four children (age: 3-5 years) were divided into the caries-free, caries-positive, and caries-active children groups by the decayed, missing and filed index. With eight individuals in each group, their dental plaques were sampled for microbial community analysis. Denaturing gradient gel electrophoresis was employed to make clear the microbial community diversity and species identity in dental plaque of the caries-free, caries-positive, and caries-active children groups. Fluorescentin situ hybridization was used to investigate the numerical level of the caries-induced microbeStreptococcus spp. Quantitative PCR was carried out to analyze relative quantity ofStreptococcusmutans in total bacteria. RESULTS AND CONCLUSION:Compared with the caries-positive and caries-active children groups, microbial community diversity among samples was significantly higher in the caries-free group. Microbes abound in the caries-positive and caries-active groups might act important roles in the development of caries.Streptococcus spp. and Actinomyces spp. might be important caries-induced microbes in the caries-active group. The ratios ofStreptococcus spp. andStreptococcus mutans in total bacteria were significantly higher in the caries-free group than those in the caries-free and caries-positive groups. In summary, molecular ecology technologies can wel reflect caries-related complex microbial community in dental plaque.

BACKGROUND:Glass ionomer cements have been gradual y employed in many aspects of dental clinical field. However, low mechanical strength and antibacterial effect restrict its further applications. OBJECTIVE:To proportional y explore the effects of titanium dioxide nanoparticles on the mechanical strength and antibacterial effect of traditional glass ionomer cements. METHODS:Base on different mass fractions of titanium dioxide nanoparticles in glass ionomer cements, al the glass ionomer cement samples were divided into control group (no titanium dioxide nanoparticles), low titanium dioxide group (containing 3%titanium dioxide nanoparticles), medium titanium dioxide group (containing 6%titanium dioxide nanoparticles), and high titanium dioxide group (containing 9%titanium dioxide nanoparticles). A universal material testing machine and a hardness tester were used to examine flexural strength, compressive strength, and surface hardness of glass ionomer cement samples, respectively. Glass ionomer cement samples were immerged into the artificial saliva, and fluoride release was measured by using a fluoride ion selective electrode. The direct contact test was used to investigate antibacterial effect of glass ionomer cement samples towards Streptococcus mutans. RESULTS AND CONCLUSION:Compared with the control group, few titanium dioxide nanoparticles (low and medium titanium dioxide group) could significantly improve flexural strength, compressive strength and surface hardness of glass ionomer cement samples (P<0.05), and high titanium dioxide nanoparticles (high titanium dioxide group) significantly decreased flexural strength, compressive strength and surface hardness (P<0.05). The introduction of titanium dioxide nanoparticles had little effect on fluorine release behavior of glass ionomer cement samples, and greatly improved antibacterial effect of glass ionomer cement samples towards Streptococcus mutans.

BACKGROUND:Modified glass ionomer cements improve the mechanical properties, abrasion resistance and beauty of traditional glass ionomer cements, and therefore they have been gradualy adopted in many fields of oral clinical application. However, it is not clear that the fluoride release behavior and soluble characteristics. OBJECTIVE:To investigate the fluoride release behavior and soluble characteristics of four glass ionomer cements in artificial saliva: Fuji II tranditional type, Fuji Plus hydroxyapatite modified type, Fuji IX metal modified type, and Fuji II LC light-curing resin modified type. METHODS: For each glass ionomer cement, cylindrical specimens were made and immerged into the artificial saliva. Fluoride release within 0-28 days was measured by using fluoride ion selective electrode. The weight of specimens was measured by using an analytical balance to further calculate the solubility. SPSS and Origin software were used for statistical analysis and nonlinear regression analysis, respectively. RESULTS AND CONCLUSION:For each glass ionomer cement, the fluoride release was peaked at the first day, decreased rapidly for the folowing several days, and then kept relatively stable at the end. The daily amount and accumulation of fluoride of Fuji II LC were significantly higher than those of other three glass ionomer cements (P < 0.01). The formula (Y=a + b* t0.5 + c* t) could better simulate the variation of fluoride release accumulations, and the fluoride release accumulations were in approximate proportional relationship with solubility. Fuji II LC reached the maximum fluoride release accumulations and the maximum ratio of fluoride release accumulations to solubility.
