BACKGROUND: Rheumatoid arthritis(RA) is an autoallergic disease,but its immunological pathogenesis has not been completely known. T lymphocytes, especially CD4+ TH1/TH2 cells, may have an important effect in the occurrence and development of RA.OBJECTIVE: To investigate the action of CD4+ TH1 and TH2 cells which separately mediate cellular immunity and humoral immunologic response (respectively) function in the occurrence and development of RA.DESIGN: Case-control, comparative observation.SETTING: Department of Immunology, Medical College of Chinese People's Armed Police Forces.PARTICIPANTS: Totally 15 patients with RA hospitalized in the Department of Internal Medicine of General Hospital of Tianjin Medical University between March 1999 and March 2000 were selected for a RA patient group, consisting of 2 males and 13 females. Of them, 12 patients whose serumal rheumatoid factor (RF)was positive and the three others' was negative. At the same time, 30 healthy individuals from persons receiving health examination in the hospital or from our department were selected for a healthy control group, consisting of 4 males and 26 females. Informed consents were obtained from the participants.peripheral blood mononuclear cells(PBMC) from the two groups of subjects were detected by enzyme-linked immunospot assay (ELISPOT). 200-500 lymphocytes were counted under a normal light microscope, and the perwhich secreted cytokines were detected by ELISPOT, and those which had red spots in their plasma after staining were positive cells. Among them,the cells secreting γ-interferon (IFN-γ) were Tm cells while those secreting interleukin-4 (IL-4) were TH2 cells. 200-500 lymphocytes were counted under a normal light microscope and the percentages of TH1 and TH2 cells square test were used for comparing statistical differences of data between the two groups.MAIN OUTCOME MEASURES: Quantitative analysis of T lymphocyte subsets (including CD3+ T cells, CD4+ T cells and CD8+ T cells) and CD4+ TH1/TH2 cells in peripheral blood from the two groups of subjects.RESULTS: Analysis of the results was from the study on all of subjects percentages of total T cells (CD3+ T cells), CD4+T cells and CD8+F cells in peripheral blood were not significantly different between the two significantly higher in RA patient group than that in healthy control group [(24.44±5.25)%, (14.93±3.82)%, P ＜ 0.05],while in RA patient group the percentage of TH2 cells and ratio of TH1 cells to TH2 cells from peripheral blood were not significantly different as compared with those of control group(P ＞ 0.05).CONCLUSION: Cellular immunologic function mediated by TH1 cells may be associated with the occurrence and development of RA.

Objective To study the correlation between the hope levels and medical coping modes of maintenance bemedialysis(MHD) patients.Methods 118 hemodialysis patients were sampled from a hospital in Fuzhou city in October,2007.A survey was conducted among these patients by questionnaires.And the col-lected data were analyzed with SPSSll.5.Results 98.3% of surveyed patients got a mediate or high-level in hope level.Compared to common patients,MHD patients got a higher score both in wriggly and subdued coping modes,and a lower score in facing mode.The choice of coping modes was affected by the hope levels of MHD patients.Conclusions Pafients with higher hope level tend to adopt wriggly and facing coping modes,while those with lower hope level generally take subdued coping mode.The nurses should help MHD patients seek supports from others in order to increase their hope level and promote them to adopt effective coping modes,in doing 80,it Can promote their mental healthy and improve their qu~ty of life.

Objective To investigate the relationship between occurrence of unexplained recurrent spontaneous abortion(URSA) and immune function of T lymphocytes. Methods T lymphocyte subsets and CD + 4 T helper subsets (including T helper 1 and T helper 2 cells) in peripheral blood from 30 cases with URSA and 24 healthy women (controls) were detected by enzyme-linked immunospot assay (ELISPOT). Results The percentage of CD + 4 positive T lymphocytes in URSA group was higher than that in the controls (60% vs 45%, P

Objective: To discuss the applied effect of high frequency repetitive transcranial magnetic stimulation combined with cognitive intervention for stroke patients with aphasia. Methods: 84 stroke patients with aphasia were divided into observation group (42 cases)and control group (42 cases). Patients of control group were treated by routine intervention of language training, while patients of observation group were treated by high frequency repetitive transcranial magnetic stimulation combined with cognitive intervention. A series of evaluated indicators, such as the language function score of Boston diagnostic aphasia examination(BDAE), the anxiety symptom score of Hamilton anxiety scale(HAMA), the quality of life and degree of satisfaction, were adopted to compare the post-treatment effect for the two groups. Results: After the treatment, there were statistical significance in the difference of understanding, retelling ability, reading ability and writing ability about BDAE scores between the two groups (t=3.572, t=4.482, t=6.238, t=3.013; P<0.05), and the HAMA scores of observation group was significant higher than those of control group (t=3.472, P<0.05). Besides, through different interventions, the series of indicators about quality of life, such as physical function, mental function, social function and material function, of observation group were higher than those of control group (t=4.513, t=3.923, t=4.473, t=4.033; P<0.05). And the satisfaction of observation group was significant higher than that of control group (x2=5.233, P<0.05). Conclusion: The clinical effect of high frequency repetitive transcranial magnetic stimulation combined with cognitive intervention for stroke patients with aphasia is favorable. And this method can increase quality of life and satisfaction for patients, and can extremely reduce medical dispute and improve the therapeutic level of hospital for stroke patients with aphasia.

Tumor markers of breast cancer are closely related to its biological behaviors and are essential for treatment strategy making. Although traditional immunohistocbemistry(IHC) is the most commonly used molecular pathological method for tumor marker detection, it can not meet the clinical requirements for quantitative and individualized treatment. With the unique photo-physical properties of quantum dots(QDs), QDs conjugated probes have been successfully used in molecular and in vivo imaging, in the study on mechanism of drug delivery and targeted therapy and especially in the detection of tumor markers in vitro and molecular targeted diagnosis of breast cancer and individualized treatment strategy making. The technique has a broad prospect in clinical application.

Objective To explore the effect of the simvastatin administration on the expression of connective tissue growth factor （CTGF） in fihrotic lungs of rats. Methods The cats were treated with single intratracheal instillation of bleomycin （BLM） or instillation of the same volume of normal saline （NS） as a control. The administration of simvastatin（20 mg/kg）began once a day immediately or 7 days later after intratracheal BLM instillation respectively with the same volume of NS was given as a vehicle control. The rats were killed on day 7,14 and 28 respectively. Pathological alteration of lung tissue was observed hy HE staining and Masson staining. Hydroxyproline（HYP）content in lung tissue was used to determine the severity of pulmonary fibrosis. The expression of CTGF in lung tissue was exanfined by immunohistochem- istry staining and photodeusitometry. Results Histopathological changes of pulmonary fibrosis emerged gradually after the instillation of BLM. The expression level of CTGF was increased in lungs of rats after intratracheal instillation of BLM, compared with the control. The administration of simvastatin immediately or 7 days after intratracheal instillation of BLM, attenuated the histopathological changes of bleomycin- induced puhnonary fibrosis and prevented the increased expression of CTGF in lung tissue on day 28. Conclusion The adntinistration of simvastatin, immediately or 7 days after intratracheal BLM instillation, prevented the up-regulation of CTGF in fibrotic lungs of rats, which ntight be one of the mechanisms of the anti-fihrosis of simvastatin in lungs.
