Objective To observe the expression of c-fos mRNA and protein in fluoride treated mouse fibroblast (FB) and osteoblast (OB) and to further explore the effects of c-fos in the osteogenic action of FB. Methods Mouse FB and OB were divided into control group and six fluoride groups (0, 0.0001, 0.0010, 0.1000, 1.0000, 10.0000,20.0000 mg/L F-), and the levels of c-fos protein at 2,4,24,48,72 h and c-fos mRNA at 48 h were measured by using ELISA and RT-PCR methods. Results Compared with the control group, fluoride increased the content of c-fos protein obviously in all FB group(P<0.01); and it is increased in 0.0001,0.0010 mg/L groups at 48 h (0.73±0.04, 0.64±0.14) and 0.0001 mg/L group at 72 h(0.70±0.17) in OB compared with the control group (0.32±0.04,0.27±0.05, P<0.01). Compared with the control group (0.95±0.11), RT-PCR revealed an increasing tendency of the expression of c-fos mRNA at 48 h in FB (1.06±0.16, 1.06±0.12,1.12±0.16,1.04±0.15,1.04±0.10,1.15±0.29), but the difference was not statistically significant(P>0.05); however, a statistically significant difference(P<0.01) of c-fos mRNA in 20.0000 mg/L group(1.40±0.17) in O B was found compared with the control group (1.06±0.06). Conclusion The higher expression of c-fos mRNA and protein in FB induced by fluoride may play an important role in the transformation of osteoblastic phenotype as well as increase the osteogenesis ability in FB.

Objective To investigate the serum concentration of 25-hydroxyl vitamin D in the common autoimmune diseases and whether the differences of the 25-hydroxyl vitamin D level exist in different autoimmune diseases.Methods 137 cases of autoim-mune diseases,including 71 cases of rheumatoid arthritis(RA),36 cases of systemic lupus erythematosus(SLE),16 cases of Sjogren syndrome(SS)and 14 cases of ankylosing spondylitis(AS),in our hospital from January 2012 to April 2013 were selected as the re-spondents.The serum samples were collected for detecting the 25-hydroxyl vitamin D level by the electrochemiluminescence method and comparing the differences of the 25-hydroxyl vitamin D level among different autoimmune diseases.At the same time whether the differences in the proportion of the normal level,insufficiency and lack of 25-hydroxyl vitamin D exist among different kinds of disease.Results The serum 25-hydroxyl vitamin D concentration had statistically significant difference among the patients with dif-ferent autoimmune diseases(P =0.006),which in the RA group was significantly higher than that in the other groups;the propor-tion of 25-hydroxyl vitamin D insufficiency in RA,SLE,SS and AS were 29.6%,52.8%,62.5% and 57.1% respectively,which in the SLE,SS and AS groups was significantly higher than that in the RA group(P <0.05).Conclusion The 25-hydroxyl vitamin)D insufficiency is general in common autoimmune diseases,the vitamin D supplements needs to be strengthened.

Objective To establish the reference interval for serum prostate-specific antigen (PSA) in apparent healthy men of different ages in Nanjing.Methods A total of 25 820 healthy men undergoing routine physical examinations in the First Affiliated Hospital of Nanjing Medical University from October 2013 to September 2015 were selected for the study.All of them were screened by prostate B ultrasound,excluding abnormal urinary tract diseases.The concentration of serum PSA and free prostate-specific antigen (fPSA) were measured by automatic luminescence immunoassay analyzer,and the fPSA/PSA values were calculated.The participants were divided into four groups (20～ 39,40～ 59,60～ 79 and older than 80 years old groups),then the median,5th,25th,75th and 95th percentiles of both PSA and fPSA/PSA were counted,respectively.Results The median of PSA (95th percentile ranges) of these groups by age from low to high were 0.78 (1.93),0.90 (2.93),1.34(6.60) and 2.01(11.91),respectively.The 25th to 75th percentiles were 0.55～1.11,0.61～1.36,0.77～2.51 and 0.94 ～ 4.19,respectively.The median of fPSA/PSA (95 th percentile ranges) were 0.37 (0.60),0.31 (0.56),0.28 (0.53) and 0.29(0.52),respectively.The 25th to 75th percentiles were 0.28～0.46,0.23～0.40,0.22～0.36 and 0.23～ 0.37,respectively.Among all the groups,median differences of both PSA and fPSA/PSA were statistically significant (P＜0.05),and PSA levels rise with age.PSA levels in different regions were different.Conclusion The PSA level of men under 40 years in Nanjing should be 0～2.5 ng/ml,40～60 years should be 0～4 ng/ml,while men who are above 60 years,could use 0～5 ng/ml as reference interval.
