Objective To explore the phenotypic characteristics of T lymphocyte subsets in the peripheral blood (PB) of Patients with rheumatoid arthritis.Methods forty-seven patients with ankylosing spondylitis (AS) and 36 health control were selected as our subjects.The patients were divided into definite Diagnosis AS group and potential AS group according to symptom and X-ray,flow cytometry was applied to measure T lymphocyte subsets and HLA-B27 of peripheral blood.At the same time,the levels of ESR,CRP and IgA were also measured.The correlation between T lymphocyte subsets and CRP HLA-B27,IgA level was analyzed.Results There was no significant difference between The definite diagnosis AS patients and healthy controls regarding of the percentages of CD3 + cells in peripheral blood,However the percentage of CD4 + cells in definite diagnosis AS patients was significantly increased than that of healthy controls (P ＜ 0.05).The ratio of CD4 +/CD8 + cells was 3.80 ± 0.28 in AS patients,higher than that of potential AS patients.T lymphocyte subsets were showed an increase tendency as the increase the level of CRP,IgA.Conclusion Lower CD8 + cell and higher CD4 + cell were showed in the peripheral blood of AS patients,which was correlated with the disease activity and suggesting T cells might be involved in the pathogenesis process of AS.Meanwhile our data indicated that the immune response might be a susceptible factor of AS and early detection of T lymphocyte subsets might provide a diagnosis and treatment basis for diagnosis of AS.Therefore the disorder of T lymphocyte subsets might play an important role in the development of rheumatoid arthritis.

Objective To evaluate the effect of vacuumassisted closure (VAC) combining surgical treatments on chronic osteomyelitis after severe open fractures. Methods Fifty-eight patients with severe high energy open fractures were enrolled,35 patients were randomized to the experimental group and had identical treatment except that VAC was applied to the wounds between irrigation and debridement procedures, 23 patients were randomized to the control group and underwent initial irrigation and debridement followed by standard fine mesh gauze dressing. The infection rate, therapeutic effect and health condition were evaluated between the two groups. Results All patients were followed up for 14 - 36 (28.0 ± 7.3 ) months.Control group developed 7 cases ( 30.4%, 7/23 ) with deep infections, whereas experimental group developed 2 cases (5.7%,2/35) with deep infections. There was significant difference between the two groups (P =0.024). There were 24 cases (68.6%,24/35) grade A healing in experimental group,whereas there were 13cases (56.5%, 13/23) grade A in control group,the difference was very singificant (P＜0.05). The health total score of experimental group was higher than that of control group at 3,9 months after operation (P =0.013,0.005). Conclusions Patients treated with VAC have a higher recovery rate,shorter length of stay and satisfactory curative effect compared with patients randomized to the traditional methods. VAC represents a promising new therapy for osteomyelitis after severe open fractures.

Objective To understand the epidemiologic feature of human parainfluenza virus type 3 (HPIV-3) in Shanghai,and to provide scientific evidence for formulating prevention and control measures in the future.Methods A total of 164 nasopharyngeal aspirates samples taken from children with acute respiratory infection (ARI) were collected from Xinhua Hospital Affiliated to Shanghai Jiaotong University and sent to Shanghai Public Health Clinical Center from June 2009 to June 2010.Samples were detected for HPIV-3 by reversed transcription-polymerase chain reaction (RT-PCR).Full-length hemagglutininneuraminidase (HN) gene (1 719 bp) of five positive samples were sequenced for phylogenetic analysis.Comparison between two groups was evaluated by the precise chi-square test (two sided).Results Of 164 samples,70 samples were infected with parainfluenza virus,and HPIV-3 was detected positive in 23 samples with the positive rate of 32.86％.HPIV-3 infections were most common in spring and summer,and most of infections were mainly found in 13-36 month-old infants.Five Shanghai isolates and 36 reference sequences from different countries and areas were divided by HN gene-based phylogenetic tree into three clusters (A,B and C).Five Shanghai isolates and five Beijing isolates belonged to C3a group.The homologies of nucleotide and amino acid sequences between five Shanghai isolates and five Beijing isolates were 99.0％-99.5％ and 99.7％-100.0％,respectively.Conclusions HPIV-3 accounts for a high proportion in children with ARI in Shanghai.C3a group may be the main lineage of HPIV-3,which suggests that HPIV-3 may be of regionally correlation.

Objective Toinvestigate the related risk factors of newly diagnosed diabetes among residents aged over 40 years in Nanjing City , and to provide evidence for diabetes prevention. Methods The clinical data were collected from the diabetes epidemiologic investigation among residents aged 40 -79 years from 6 communities in Nanjing City. Univariate and multiple logistic regression analyses were performed to analyze the potential risk factors for newly diagnosed diabetes. Results The prevalence rate of new diagnosed diabetes from 8039 subjects was 10.87%. A higher prevalence rate of new diagnosed diabetes was found in male than that in female (13.15% vs. 9.74%, P < 0.01). Multiple logistic regression analyses revealed that the main risk factors for newly diagnosed diabetes were male, age, family history, body mass index (BMI) and less physical activity after adjusting other factors (adjusted OR 1.339-1.862, P < 0.05). Conclusions Male, age, family history, body mass index (BMI) and less physical activity may be the main risk factors for diabetes among residents in Nanjing City.

The nanocomposites of poly-diallyldimethylammonium chloride (PDADMAC) and CdTe quantum dots (QDs) (i.e.QDs-PDADMAC nanocomposites) have been prepared based on electrostatic interaction and their fluorescence stability in aqueous solution has been investigated. MTT method(3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazoliumbromide method) was used to study their cytotoxicity and A549 lung cancer cell as a model cell was also used to evaluate their cellular imaging.It was shown that the fluorescence stability of QDs-PDADMAC nanocomposites was much better than that of bare QDs both in aqueous solution and cell.Meanwhile,QDs-PDADMAC nanocomposites display very low cytotoxicity in the low concentrations and better staining ability compared with QDs.QDs-PDADMAC nanocomposites will have great advantage on the cell analysis detection and imaging.

Objective To study the applicability of unilateral and bilateral antegrade cerebral perfusion during deep hy-potbermia circulatory arrest (DHCT) surgery and to determine a better method of brain protection. Methods 60 patients un-derwent aortic arch surgery were random divided into either unilateral cerebral perfusion group with a cannula in the innominate artery (n = 30 ) , or bilateral cerebral peffusion gToup with an additional cannula in the left carotid artery ( n = 30 ). S-100β,neuron specific enolase (NSE) were assayed at the following time points: the beginning of cardiopulmonary bypass (T_1), the beginning of circulatory arrcst( T_2 ), antegradc cerebral perfusion (ACP) 25 min( T_3 ), the end of ACP( T_4 ), the end of car-diopulmonary bypass ( T_5 ) , 1h( T_6 ) , 6h ( T_7 ) and 24h( T_8 ) after operation. Neurological deficit incidence and mortality were also obtained. Results There is no statistical significance for S-100β and NSE plasma concentration among time points of T_1、T_2 and T_3. But every time point among T_4、T_5、T_6、T_7 ,Ts do have statistical significances. The incidence of central nervous system dysfunction in group unilateral ACP was higher than that in group bilateral ACP ( 33.33% vs. 10.00%, P = 0.028 ).But there is no significant difference between the two groups in mortality( 3.33% vs. 6.66% ,P = 1. 000 ). Conclusion There is no significant difference between unilateral ACP and bilateral ACP in 25 min during DHCA. But as the DHCA time extends, the effect of bilateral ACP will be better.
