Objective To explore the diagnostic value of anti-cyclic citrullinated peptide (CCP) 3.1 IgG/IgA antibody detected by enzyme-linked immunosorbent assay (ELISA) in patients with rheumatoid arthritis (RA).Methods The ELISA was used to measure the anti-CCP3.1 antibody in the serum of 169 RA patients,100 patients with other rheumatic diseases (including systemic lupus erythematosus,Sjogren's syndrome and osteoarthritis) and 72 healthy controls.The diagnostic value of CCP3.1 was assessed and compared with the second generation of anti-CCP IgG (CCP2) antibody,the correlations between anti-CCP3.1 antibody and the clinical and laboratory parameters were analyzed.Two-independent samples t test,chi-square test and Spearman's correlation were adopted for statistical analysis.Results ① The average cut-off concentration of anti-CCP3.1 antibody was (1122±1429) U/ml in RA,(13±14) U/ml in other rheumatic diseases and (6±5) U/ml in healthy controls.② The area under curve of ROC for anti-CCP3.1 antibody and anti-CCP2 antibody were 0.923 and 0.936 respectively.There was no difference between the sensitivity (82％ vs 79％)and specificity (97％ vs 99％) of anti-CCP3.1 antibody and anti-CCP2 antibody.The Kappa values between anti-CCP3.1 antibody and anti-CCP2 antibody was 0.763.③ We also found that anti-CCP3.1 antibody was positive in 20％(7/35) of anti-CCP2 antibody negative,43％(18/42) of RF negative,62％(47/76) of AKA negative,71％(49/69) of APF negative and 13％ of autoantibodies negative patients,indicated that antiCCP3.1 antibody had a potential value in the diagnosis of serum negative patients with RA.④ The presence of anti-CCP3.1 antibody was correlated with RF,HRF-IgG,APF,AKA,GPI and IgA (P＜0.05),except disease activity.Conclusion The sensitivity of anti-CCP3.1 antibody is slightly higher than anti-CCP2 antibody.The Anti-CCP3.1 antibody is a very valuable parameter for the diagnosis of RA,especially in serum negative patients.

Objective To investigate the prognostic factors of life and functional outcome of the first hemiparetic stroke patients. Methods One hundred and eighteen stroke subjects were registered prospectively. The Barthel index (BI) , Rankin scale (RS) , Mortricity index(MI) , Mini-mental state examination (MMSE) , Montgomery-Asberg depression scale (MADRS) and a scale of general state and risk factors were used to evaluate at the 48th hour, the 15th day and the 90th day after stroke. Results The patients' performance, as demonstrated by their scores with all the evaluation instruments, changed significantly at all the time points of evaluation after stroke (P ＜0.05). There was no significant difference between the performance at the 48th hour and the 15th day after stroke ( P ＞ 0.05 ). But at the 90th day after stroke, the activity of daily living performance and the depression status recovered significantly (P ＜ 0.01 ). Logistic regression analysis showed that, such factors as pneumonia, urinary incontinence within 48th hour and deep sensation disturbance might adversely influence patients' activity of daily living performance at the 90th day after stroke; the muscle strength of upper extremities at the 48th hour, and MMSE scores at the 15th day after stroke acted as the protective factors. Conclusions The stroke patients improved significantly with regard to their clinical and functional manifestations when evaluated 90 days after stroke onset. The main factors influencing the activity of daily living performance 90 days after stroke onset included deep sensation disturbance,pneumonia, urinary incontinence and muscles strength of upper extremities at 48th hour, and MMSE scores at the 15th days after onset.

Objective: To observe the effect of Yi Jin Jing (Sinew-transforming Qigong Exercises) plus tuina on the neck for stiff neck. Methods: A total of 60 patients with stiff neck who met the screening criteria were selected and randomly divided into two groups, with 30 cases in each group. Patients in the control group received tuina on the neck, 30 min every time, once a day, while patients in the observation group practiced Yi Jin Jing (Sinew-transforming Qigong Exercises) plus the same tuina therapy as the control group, and Yi Jin Jing (Sinew-transforming Qigong Exercises) was conducted for more than 30 min every time, once a day. Visual analog scale (VAS) scores were observed before treatment, and after 1 time, 3 times and 5 times of treatment to evaluate the degree of neck pain. Results: During the treatment, each group had 2 dropouts. After treatment, the total effective rate was 92.9％ in the observation group versus 82.1％ in the control group, showing a statistical significance (P<0.05). The VAS scores in the observation group at the three time points were significantly lower than those in the control group (all P<0.05). Conclusion: Yi Jin Jing (Sinew-transforming Qigong Exercises) plus tuina on the neck can effectively relieve neck pain and improve cervical range of motion in patients with stiff neck, and can achieve a better effect than tuina alone.

Objective To analyze rural doctors′ social mentality with the theory of relative deprivation.Methods 642 rural doctors from 225 villages of 1 5 counties in Shandong were selected for a questionnaire survey.The factor analysis method was used to reduce the scale dimension and simplify the scale.Analysis of rural doctors′vertical and horizontal relative deprivation was made based on different reference groups.Results Rural doctors tend to identify themselves with rural teachers and doctors in township hospitals,and 60.0% identify themselves as the low income group.39.9% of them found a higher income,while 33.5% of them found a higher social status.76.3% of them found their social contributions are higher.91.4% of them hold that villagers benefit from the new healthcare reform policies,while 65.9% of them hold themselves as benefiting from such policies.This indicates a low sense of achievement.Conclusions Compared with the reference groups,rural doctors feel an obvious sense of relative deprivation comparing both horizontally and vertically.They hold themselves as underpaid and have little sense of achievement for the policies.In this consideration,the government should increase subsidies to lift pay for rural doctors,and to identify their legitimacy,in order to stabilize these medical workers.

The study on tumor metabolism has been gradually be-come a hot spot in recent years .A lot of proteins involved in the regulation of tumor metabolism especially the glucose transporter protein 1(GLUT1).As a key regulatory factor mediating energy metabolism within tumor cells , GLUT1 can regulate the glucose intake and maintain the basic level of metabolism in tumor cells . More importantly, the abnormal expression of GLUT1 was asso-ciated with many kinds of tumors , of which GLUT1 was used to meet the energy requirement for the fast growth of tumor .Thus GLUT1 also played a crucial role in growth , differentiation and metastasis of tumor cells and prognosis of tumors .Meanwhile , as three-dimensional crystal structure of GLUT 1 was determined , it is possible to design the small molecular inhibitors of GLUT 1, which can realize “starve to death” tumor cells.GLUT1 can be a particularly attractive target for tumor treatment and interfer-ence.The relationship between abnormal expression of GLUT 1 protein and tumor metabolism was reviewed . Moreover , the mechanism of tumor metabolism regulated by GLUT 1 protein ex-pression and treatment of cancers were discussed , which may provide references for future research and clinical treatment .

Objective To study the different types of medication guidance for community doctors in the context of essential medicine system,and analyze its influencing factors.Methods SPSS 1 9.0 was called into play for statistical analysis of data gathered,and the medication guidance behavior of the doctors were graded on the two dimensions of personal willingness and practical action.With important quadrant method,the medication guidance behavior of such doctors was classified,while the multiple linear regression was used to study the influencing factors.Results Most of the community doctors of the fourteen counties fall into the area of “high willingness and less action”,with only a few falling into the area of the “high willingness and more action”. Major influencing factors of their willingness on medication guide were found to include impacts on job autonomy,attention to essential medicine system, and the forms to improve income.Major factors of the doctors'actions on medication guide include awareness of essential medicines,awareness of essential medicines catalog,and training outcomes. Conclusion The community doctors have high personal willingness for medication guidance related to essential medicines,but only a number of them carried it in their work.Therefore,it is necessary to take actions to strengthen awareness of the doctors for medication guidance and encourage them to carry it out.
