Objective To explore the correlation between anti-cyclic citrullinated peptide(A-CCP) antibody and tumor necrosis factor(TNF)-?, rheumatoid factor(RF), ESR, PLT count and clinical features in patients with rheumatoid arthritis(RA), and the outcome of unclassified arthritis(arthralgia)patients after six months follow up. The value of A-CCP antibdy in the diagnosis of early RA and its pathogenetic roles is in- vestigated. Methods A-CCP antibody and TNF-?were detected by ELISA and the RF was tested by the rate scatting immunity method in 91 RA patients, 46 unclassified arthritis(arthralgia)patients and 45 other rheumatic diseases patients. Results A-CCP antibody levels in serum correlated significantly with TNF-?levels, PLT count and the degree of joint swelling in RA and unclassified arthritis(arthralgia)patients(r= 0.854, P=0.O00; r=0.882, P=0.000; r=0.318, P=0.002; r=0.486, P=0.001; r=0.291, P=0.005; r=0.731, P= 0.000 respectively). A-CCP antibody levels in serum was weakly negatively correlated with the gripping power in RA patients(r=0.228, P=0.030). And it was weakly correlated with ESR in unclassified arthritis(arthrai- gia)patients(r=0.365, P=0.013). Compared with other rheumatic diseases patients, A-CCP antibody levlels in serum increased significantly in RA and unclassified arthritis(arthralgia)patients(P=0.000). Compared with normal controls, it increased in other rheumatic diseases patients(P=0.011). Twenty-four patients had positive A-CCP antibody in 46 unclassified arthritis(arthralgia)patients. Thirty-two out of 46 unclassified arthritis(arthralgia)patients were early RA after 6 monthes follow up. 95.8%(23/24)unclassified arthritis (arthralgia)patients with positive A-CCP antibody were early RA. Conclusion A-CCP antibody reflects disease activity in certain extent. It's benefit to the diagnosis of early RA. High A-CCPantibody levels com- bined with high levels of TNF-?, ESR, PLT count and joint swelling can help the diagnosis of early RA.

OBJECTIVETo analyze the secular changes of physical growth in 7-17 year old students of Zang-tribe in Tibet during 1965-2004, and to make suggestions for further improvement.
METHODSThe data collected by local government in 1965 and Chinese national survey on students' physical fitness and health in 1985, 1995 and 2004 were used to analyze and find out the differences from the students' stature, body weight, chest girth, and BMI in different years, and to compare the increasing rate per 10 years in different periods of time.
RESULTSLevels on stature, body weight and chest girth were increased significantly among 7-17 year-old students of Zang-tribe in Tibet during 1965-2004. From 1965 to 1985, the levels of stature and body weight were increased 11.4 cm and 5.0 kg respectively among male Zang-tribe students, 9.1 cm and 3.9 kg among the female. During 1985-2004, stature levels of Zang-tribe students was kept rising in much less extent, while average levels of body weight were reaching up remarkably, especially in 1995-2004, in which the average increasing rate per 10 years had achieved 14.8% and 13.4% among the male and female students aged 7-17 years old respectively. Levels of chest girth were increased rapidly in 1965-1985, showing a higher increasing rate in male students (2.7%) than in female students (1.9%). In 1985-2004, the increasing rates fell obviously both in male and female students, but there existed a higher rate in 1995-2004 than in 1995-1985, especially for females (4.0%). Upon the secular changes of stature and body weight, the levels of BMI were decreased in 1985 as comparing to those in 1965, then increased rapidly in 1985-2004, especially in 1995-2004, having an increasing rate up to 12.6% and 12.4% respectively in male and female students.
CONCLUSIONSecular changes on physical growth among 7-17 year-old students of Zang-tribe in Tibet were paralleled with the economic progress in 1965-2004, giving active effects by economic progress and nutrition improvements to the physical growth of children and adolescents.

Objective To investigate the effect of 131I on apoptosis of thyrocytes in patients with Graves disease. Methods Forty-seven patients with Graves disease were divided into two groups, two week group (G2w) and four week group (G4w). All patients underwent thyoid needle biopsy before 131I treatment and the repeated biopsy at two weeks (G2w) or four weeks (G4w) after 131I treatment. The positive units of pro-apoptotic proteins (Fas, FasL) and anti-apoptotic protein (Bcl-2) were studied with immunohistochemistry staining. The differences of the two groups were compared with t-test. Liner correlation analysis was applied to study the correlation between 131I dose and apoptosis-related proteins and that between serum sTSH after 131I treatment and apoptosis-related proteins. Results Fas, FasL and Bcl-2 expression (positive units) were significantly increased in both groups after 131I treatment, G2w :22.84 ± 9.31 vs 16.20 ± 6.75,21.13±6.29vs 14.56±4.06, 21.69±7.83 vs 15.22 ±5.94, t= -3.08, -3.73, -4.05 (allP<0.05); G4w:21.69 ±4.52 vs 15.83 ±5.03, 19. 11 ±3.75 vs 14.02 ±4.98, 19.06 ±3.44 vs 16.63 ±4. 73, t = - 5.26, - 5.00, - 2.41 (all P<0.05). However, no statistical differences were found between G2w and G4w (t = 0. 53, 0. 82, 1.46, all P > 0.05). Significant correlation was found between 131I 0. 727, rFasL = 0. 763 (both P<0.05)), but not between the dose and Bcl-2, rBcl-2 = - 0. 094, 0. 102(both P > 0.05). There were significant correlation between serum sTSH three months after 131I treatment and apoptosis-related proteins, rFas = 0.433, rFasL = 0. 601, rBcln2 = - 0. 397, (all P<0. 05). Conclusions 131I can induce thyrocytes to express the pro-apoptotic proteins in patients with Graves disease.

OBJECTIVETo analyze the motor performance status in students of Han nationality in fifteen provinces in china.
METHODSTotally, 161 804 students of Han nationality aged from 7 to 18 years old were involved in the Chinese Surveillance on Students' Physical Fitness and Health in 2004. Motor abilities were accessed with the aid of gripping power, 50 m dash, standing long jump, and 1-min sit-ups. Based on general statistical description, principal component analysis and linear regression, the development characters of students' motor performance were explored.
RESULTSThis research showed some characters similar to those of last ones: motor capability was improved in correlation with age; boys did better than girls, the difference between 18 year-old rural boys and rural girls was 15.3 kg, -2.0 s, 58.6 cm, 8.7/min; the urban students performed better than the rural ones, the difference between 15 year-old urban boys and rural boys was 0.9 kg, -0.2 s, 3.5 cm, 3.5/min. The first principal component might represent the 4 tests greatly. Regression analysis on principal component quantitatively interpreted the influence of factors such as age, sex and area.
CONCLUSIONSThe general principles of exercise quality development of students are still in work. Principal component analysis should be adequate and convenient in motor performance analysis.

OBJECTIVETo analyze the role of step-test on large sample surveillance in students' physical fitness and health.
METHODSTotally, 36 237 students aged 12-, 14- and 17-year-old from fifteen Chinese provinces taking part in the 2004th National Surveillance on Students' Physical Fitness and Health were enrolled in this study. All of them passed through the step-test, of which the indices were calculated in combining with the performance time and pulse rates in resuming period. The means of step-test index were analyzed among various youth groups, and compared with the obesity, overweight and the normal-weight subjects.
RESULTSAs compared with the general level of physical growth, the means of step-test index were found higher in rural groups than in urban ones, and higher in southern groups than in northern ones. The highest means of index was found in the rural groups in having the lowest socioeconomic status, and also the lowest means found in metropolis groups having the highest socioeconomic status. These gaps were due to the change of life style, absence of physical exercise and relatively to the high body weight of the high socioeconomic-level groups. Among the obesity, overweight and normal-weight youths, the means of step-test index was shown in a gradient decrease tendency, and those significant gaps might be found between the obesity and the overweight, and the overweight and the normal-weight groups, showing that there should be harmful influences of overweight and obesity on the youth's cardiovascular function.
CONCLUSIONAs a safe and easily-taken measure for cardiovascular function, the step-test should be useful in regularly measuring the national students' physical fitness and health status.

Objective Studing the main influencing risk factors to provide evidence for improving the quality of life among people living with HIV. Methods The quality of life on 758 patients with HIV was evaluated by the Medical Outcomes Study Short-Form Health Survey (SF-36) and some potential risk factors as personal characteristics and disease condition were studied. Means and standard deviations of data were calculated and differences among groups and variances were tested using Student's t test, followed by step-wise multivariate regression. Results The SF-36 two summary scores of 758 patients with HIV appeared to be 45.34±8.77 and 41.92±12.01 respectively. The physical component surmmary scores (PCS) had a gradual decrease with the increase of age. However, mental component summary scores (MCS) had a gradual decrease with the increase of time receiving the treatment. Male patients reported having a better quality of life (QOL) than female, and patients who were infected through injecting drug use and sexual transmission reported to have had better QOL than patients who were infected through paid blood plasma donation. Compare to patients having low CD4+ count, those having higher CD4+ count reported to have better QOL. Conclusion Patients being young, female, infected through paid blood plasma donation, having low CD4+ count, or treated for longer period, would have unsatisfactory QOL.
