Objective To investigate mechanism and clinical effect of implantation of pacemaker with artial fibrillation(Af) preventive pacing algorithms (Vitatron 900E).Method 24 cases of patients with paroxysmal Af were observed in three phases (each phase two weeks):⑴Monitoring phase,in which onset mechanism of atrial arrtythmias was recorded, the device was programmed into DDD mode with 60 bpm;⑵Lower rate limit phase (LRL),DDDR mode with 85bpm LRL, and evaluating anti-Af effect by elevated rate;⑶Preventive pacing therapy phase,all preventive pacing therapies with programming to on or off, and this phase determined whether combined pacing therapies impacted on incidence of Af. Results 24 cases of patients were free of Af, in which 17 cases were done by using post-PAC-response or/and post-exercise-rate-control therapy only, and 7 cases of 17 casees were done by combining it with cordarone 0 1～0 2g/d also. The other 7 cases were done by DDDR 85 bpm only.Conclusions Af prevention pacing may be benefit for patients with paroxysmal Af,especially with complicated symptomatic bradycardia.

Objective To investigate the diagnosis and surgical treatment of peripheral solitary pulmonary nodule (SPN).Methods From January 2007 to October 2012,the clinical data of 69 cases of SPN treated were analyzed prospectively.And postoperative pathologic examination results as the gold standard to determine spiral CT enhanced check the accuracy and consistency test (Kappa test).Results Twenty-eight cases were diagnosed as malignant SPN by preoperative CT,25 cases were diagnosed as malignant SPN by postoperative pathology.The accuracy of CT judgment SPN benign and malignancy was 89.3％ (25/28),the Kappa value was 0.503.All patients were followed up for 6-12 (9.6 ± 1.4) months.There was no recurrence or enlargement.Conclusions Enhanced spiral CT scan is more economical and practical way for identifying benign and malignant SPN.Malignant SPN diagnosed by CT should be considered having surgery and auxiliary thoracoscopy combined with intraoperative rapid freezing to determine the surgical approach.

0.05).The acute toxicity was more severe in the no-response group and response-LCAF group than in the response-CF group.Conclusion:LCAF did not improve the local control rate and survival rate on grades Ⅰ&Ⅱ esophageal carcinoma when 40Gy had been given by CF.Grades Ⅲ&Ⅳ esophageal carcinoma will get benefit from LCAF.

Objective To investigate the effect of prostaglandin E1(PGE1) on the expression of monocyte chemoattractant protein-1(MCP-1)in human umbilical vein endothelial cells (HUVECs) and its possible mechanism. Methods Endothelial cells were incubated with oxidized low-density lipoprotein (ox-LDL group) in the presence or absence of prostaglandin E1. The level of MCP-1 in the supernatants was determined by enzyme linked immunosorbent assay (ELISA), the expression of MCP-1 mRNA in cultured endothelial cells was detected by in-situ hybridization and the protein expression of NF-κB was analyzed by Western blot. Results Compared with ox-LDL(100 μg/ml),PGE1 markedly lowered the levels of MCP-1[(0. 327±0. 051),(0. 214±0. 213),(0. 247±0. 228)pg/ml vs. (0. 655±0. 013)pg/ml], inhibiting the expression of MCP-1 mRNA [(0. 061±0. 008), (0. 033±0. 006),(0. 026±0. 004)A/μm2 vs. (0. 220±0. 032)A/μm2] in the cultured HUVECs in a dosedependent manner (0. 001, 0. 01, 0.1 mol/L). Western blot analysis demonstrated that the amount of NF-κB p65 was attenuated after treatment with prostaglandin E1 for 24 hours. Conclusions Prostaglandin E1 can downregulate the expressions of MCP-1 and NF-κB induced by ox-LDL in HUVECs, which may thereby defend the blood vessel endothelial cell function.

Objective To investigate the expression of regulatory T cells in the peripheral blood of rheumatoid arthritis patients and to explore the possibility of using CD127 instead of FOXP3 in the study of regulatory T cells. Methods Thirty-two patients with active rheumatoid arthritis (RA) [ including 20 patients who hadn't been treated with disease modifying antirheumatic drugs (DMARDs) and 12 patients whose disease were poorly improved after DMARDs therapy], 25 patients with primary Sjogren's syndrome (pSS) and 24 healthy controls were selected. The percentages of CD4+CD25high, CD4+CD25+CD127low/'- and CD4+CD25+ FOXP3+T cells were analyzed by 3-color flow cytometry. Meanwhile, the levels of CRP, ESR, immunoglobulin and complement were measured. Results Percentages of CD4+CD25+CD127low/-T cells and CD4+CD25+FOXP3+ T cells in RA patients were significantly lower than those of healthy controls (P<0.01 for each category of T cells),but the percentage of CD4+CD25high T cells didn't show significant changes (P>0.05). The expression of CD4+CD25+CD127ow/- and CD4+CD25+FOXP3+T cells showed no difference between RA and pSS patients (P> 0.05 for each). Differences of the three group cells between untreated RA patients and poorly-improved RA patients were not significant (P>0.05 for each case). CD4+CD25+CD127low/-T cells were positively associated with CD4+CD25+FOXP3+T cells (r=0.698, P=0.001), but the two groups had no correlation with the levels of CRP, ESR and anti-CCP antibody and RF (P>0.05 for each case). Conclusion The percentage of CD4+CD25+CD127low/-T cells is decreased in the peripheral blood of active RA patients and positively correlates with CD4+CD25+FOXP3+T cells.It suggests that CD127 may be an ahemative marker of FOXP3 in the study of Treg cells.

Objective To study the role of peripheral blood T regulatory cells (Treg) markers, as well as different Treg cells in the pathogenesis of systemic lupus erythematosus (SLE) and explore the correla-tion betweenCD127 and Foxp3. The immunosuppressive effect of CD4~+CD25~+CD127~(low/-) T cell is explored. Methods ①Four-color direct fluorescence-labeled and multi-parameter flow cytometry were used to detect peripheral blood CD4~+CD25~+ T cells and other Treg cells accounted for the proportion of CD4~+ T cells in 40 SLE patients (19 cases with active disease 21 cases in remission) and 15 healthy controls. Meanwhile, its correlations with anti-dsDNA antibodies among 7 groups were analyzed.②Flow cytometry sorting combined with cell culture were applied to detect and analyze the proliferation inhibition effect of CD4~+CD25~+CD127~(low/-)regulatory T cells to CD4~+CD25~-effector T cell.Two independent samples t test,ANOVA for repeated measures,Pearson's correlation and Spearman's correlation were used for statistical analysis.Results ①The cell ratio of the 7 groups of SLE patients was(6.1±1.7)%,(3.1±1.3)%,(2.1±1.0)%,(1.6±0.3)%(0.97±O.28)%,(0.69±0.23)%and(O.71±0.35)%respectively.In the SLE group,the proportion of the first 6 groups was lower than the control group (P<0.05).For CD4~+CD127~(low/-)Foxp3~+,there wag no difference in the two groups(P>O.05).②CD4~+CD25~+Foxp3~+,CD4~+CD25~(high)Foxp3~+ T cells and IgA ratio Was positivelv correlated.While CD4~+CD25~(high)CD127~(low/-) T cells and anti-SSB antibodies was positively correlated in SLE patients.③The seven group of cells,in addition to CD4~+CDl27~(low/-)Foxp3~+ T cell ratio were lower in early-onset SLE patients than those in patients at remission(P<0.05).④The cell propor-tion of the first 6 groups was lower than that of post steroid treatment(P<0.05).⑤Foxp3 expression of CD4~+CD25~+T ceils and CD4~+CD25~(high) T cells was positively correlated with low expression of CDl27 in the early onset group,remission group and the control group.⑥The CD4~+CD25~- effect T cells could be suppressed by their own CD4~+CD25~+CDl27~(low/-) regulatonry T cells in vitro,and the inhibition of SLE patients was significantly lower than controls.Conclusion The immunological abnormality of SLE may be associated with the qnatity and functional defects of immune regulatory T cells.CDl27 may be a possible alternative to Foxp3 regulatory T cell-specific surface markers.
