Objective To investigate the variation of immune index in patients with systemic lupus erythematosus (SLE) treated with autologous purified CD+34 cells transplantation and to clarify the relationship with pathogenesis and prognosis. Methods Flow cytometry (FCM) and enzyme linked immunosorbent assay(ELISA) were used to test lymphocyte subsets, C3, C4, CH50, autoantibodies and immunoglobulin for 18 cases of SLE before and after transplantation. Results The results showed that the ratio of all the T cell subsets reduced obviously in early postgraft and recovered gradually in 1 to 3 months after transplantation except CD45 RO+CD+4 cells. The levels of serum C3, C4, CH50 increased significantly after transplantation. No case relapsed within one year after transplantation, but 2 patients relapsed one year after transplantation. The levels of the indexes in the patients with relapse were significantly lower than those in the patients with persistent remission, including C4 in the entire course, CH50 in the 3rd and 12th month after transplantation and CD45 RA+ CD+8 cells in the 6th month after transplantation. However, the ratio of CD45 RO+ CD+4 cells in the first month after transplantation in the patients with relapse was higher than that in the patients with persistent remission. Conclusion Autologous purified CD+34 cells transplantation is effective for treating SLE. Survey of immune indexes before and after transplantation is important to investigate the pathogenesis of SLE. Moreover, these immune indexes can be used to predict therapeutic efficacy of SLE.

Objective: To observe the therapeutic efficacy of acupoint application at different groups of acupoints in treating bronchial asthma in remission stage. Methods:A total of 120 patients with bronchial asthma in remission stage were recruited and divided by the random number table method into acupoint application group 1, acupoint application group 2 and acupoint application group 3, with 40 cases in each group. In all the three groups, Tiantu (CV 22), Dazhui (GV 14) and Feishu (BL 13) were selected, with Dingchuan (EX-B 1) added in acupoint application group 1, Shenshu (BL 23) added in acupoint application group 2, and Gaohuang (BL 43) added in acupoint application group 3. Before intervention, one month and 3 months after intervention, clinical symptoms, peak expiratory flow (PEF) andforced expiratory volume in 1 second percentage of predicted value (FEV1％) of the three groups were observed, and their clinical efficacies were evaluated. Results: Comparing the therapeutic efficacy regarding traditional Chinese medicine symptoms and signs, after 1-month treatment, the total effective rate was 87.5％ in acupoint application group 1, versus 62.5％ in acupoint application group 2 and 55.0％ in acupoint application group 3, and the between-group differences were statistically significant. After 3-month treatment, the total effective rate was 95.0％ in acupoint application group 1, versus 70.0％ in acupoint application group 2 and 65.0％ in acupoint application group 3, and the between-group differences were statistically significant. After intervention, the three groups all showed significant improvements in pulmonary function with statistical significance; among the three groups, the improvement in acupoint application group 1 was more significant than that in the other two groups. Conclusion: Tiantu (CV 22), Dazhui (GV 14) and Feishu (BL 13) as basic prescription plus Dingchuan (EX-B 1) can improve symptoms of bronchial asthma in remission stage, and it works better in improving pulmonary function than the basic prescription plus Shenshu (BL 23) or Gaohuang (BL 43).

OBJECTIVETo examine whether acupuncture treatment would improve outcome in chronic Achilles tendinopathy.

METHODSA randomized, controlled trial at two centers of 64 randomized patients aged 18 to 70 years with chronic Achilles tendinopathy was conducted from July 2007 to April 2010, with follow-up until October, 2010. These patients were randomly allocated into an acupuncture treatment group (acupuncture group) and an eccentric exercises group (control group). The validated Victorian Institute of Sports Assessment-Achilles (VISA-A) questionnaire was completed at baseline and 8, 16, and 24 weeks. The pain at rest and after activity was accessed at baseline and 8 weeks with Visual Analogue Scale (VAS).

RESULTSAfter randomization into the acupuncture group or control group, one patient was loss of follow-up. The mean VISA-A score improved signifificantly after 8 weeks in the acupuncture group to 67.1 points [95% confifidence interval (CI), 64.1-70.2] and in the control group to 48.5 points (95% CI, 45.5-51.6) with an additional 18.6 points increase in acupuncture treatment patients (P=0.0000). Acupuncture treatment resulted in a significant increase from baseline in VISA-A of 25.8 after 16 weeks and 28.4 after 24 weeks. Whereas, in the control group the increase from baseline in VISA-A were 10.0 and 16.6 after 16 and 24 weeks, respectively (P=0.0000). The VAS diminished by 2.0 cm after activity, and by 1.5 cm at rest after 8 weeks in the control group. In the acupuncture group, the pain scores diminished significantly more than in the control group, with pain reduction of 3.7 cm after activity (P=0.0000) and 3.2 cm at rest (P =0.0000).

CONCLUSIONAcupuncture intervention could improve pain and activity in patients with chronic Achilles tendinopathy compared with eccentric exercises.

Abstract: Objective　To develop a real-time fluorescent quantitative RT-PCR (qRT-PCR) method for qualitative and quantitative Chikungunya virus (CHIKV) analysis. Methods Based on the systematic analysis of the genomic sequences of Chikungunya and its related arboviruses, the specific nucleic acid sequences for Chikungunya virus were screened and identified, and then the primers and TaqMan probe were designed. Meanwhile, the human GAPDH gene was used as an internal reference. The reaction system for qRT-PCR was systematically optimized by L9(34) orthogonal design, and a rapid detection method for Chikungunya by qRT-PCR based on TaqMan probe methods was established. The sensitivity, specificity, reproducibility, and coverage of the established method were analyzed in detail. The standard curve was made, and the absolute quantitative method was established using the cloned nucleic acid fragments as positive samples. Results　A real-time fluorescent quantitative RT-PCR assay was developed for the qualitative and quantitative analysis of Chikungunya virus. The reaction system included Chikungunya virus and reference internal gene specific primers and probe, RT/Taq enzyme mixture, reaction buffer, and negative and positive reference. The established method obtained positive results with the ROSS strain of ECSA subtype, LR2006 strain of IOL branch, 181/25 strain of Asian type and Dongguan 2010 epidemic strains of Chikungunya virus, but there was no cross-reaction with other 18 arboviruses belonging to Flaviviruses, Alphaviruses and Bunyavirus. The minimum detection limit of the established method was 5.80 copies/mL, and a linear relationship was observed between the amount of input plasmid DNA and fluorescence signal value over a range of 5.80×102 copies/mL to 5.80×1010 copies/mL, and the correlation coefficient was 0.999 5. The qRT-PCR amplification efficiency was 91%, and the intra-assay variations and inter-assay variations were 0.01-0.07 and 0.03-0.11, respectively. Conclusions　The TaqMan qRT-PCR method developed in this study can qualitatively and quantitatively detect Chikungunya virus rapidly with specificity and sensitivity, providing a technical method for the prevention and control of this viral disease.

BACKGROUNDSevere bilateral carotid stenosis caused by atherosclerosis has not been unusual in the elderly. Such patients have high stroke risk. Many studies show that carotid artery stenting (CAS) is an alternative to treat unilateral carotid stenosis. However, the optimal procedural strategy of bilateral carotid stenosis remains unclear. The purpose of our study was to evaluate the safety of simultaneous bilateral carotid artery stenting (SBCAS) compared with unilateral carotid artery stenting (UCAS).

METHODSIn this single-center retrospective study, we analyzed 234 consecutive patients who underwent carotid stenting from January 2005 to December 2009. Thirty-nine patients (16.7%) of them underwent SBCAS, and the others (n = 195) underwent UCAS. Indication for CAS was defined as carotid artery diameter reduction > 60% (symptomatic) or > 80% (asymptomatic). Six-month and 30-day hemodynamic depression (HD), hyperperfusion syndrome (HPS), stroke, death and myocardial infarction (MI) after carotid stenting were assessed.

RESULTSSBCAS group had no more HD and HPS compared with UCAS group at 30 days (HD: 28.2% vs. 20.0%, P = 0.396; HPS: 2.6% vs. 2.1%, P = 0.262). Moreover, there was no statistically significant difference between SBCAS group and UCAS group in major stroke, death, MI and their combinations within 30 days (major stroke: 0 vs. 3.6%, P = 0.604; death: 2.6% vs. 1.5%, P = 0.520; MI: 2.6% vs. 0.5%, P = 0.306; and their combinations: 5.1% vs. 4.6%, P = 1.000) and 6 months (major stroke: 0 vs. 3.6%, P = 0.604; death: 5.1% vs. 2.1%, P = 0.262; MI: 5.1% vs.1.0%, P = 0.130 and their combinations: 7.7% vs. 5.1%, P = 0.459).

CONCLUSIONSThe patients undergoing SBCAS had no more events than those undergoing UCAS in 30-day and 6-month follow-up. Our finding suggests that SBCAS appears to be as safe as UCAS.

This study was purposed to explore the feasibility of simultaneous analysis of telomere length and cell surface antigen by multicolor Flow-FISH to assess minimal residual disease (MRD) in leukemia. The telomere length in 34 leukemia patients versus 20 normal controls was compared by using Flow-FISH, and the relationship between telomere length and therapeutic effect and prognosis was analyzed preliminarily. As for those patients with follow-up samples, the changes of telomere length combined with surface antigen in different courses of disease were observed by multicolor Flow-FISH. The results indicated that the telomere length of de novo patients was significantly shorter than that of controls except the patients in chronic myeloid leukemia-chronic phase (CML-CP). The shorter telomere, the lower complete remission (CR) rates were observed in acute leukemia cases and the shorter duration of CP before onset of blast phase (BP) occurred in CML cases. The acute leukemia patients showed longer telomere and fewer cells expressed the related antigen after CR. The telomere length of cases with continued CR remained at normal level during remission, and there was no increased expression of the specific antigen. However, the telomere of relapsed cases shortened again after relapse with elevated specific antigen expression. In the relapsed cases, the telomere of related antigen positive cells shortened ahead of telomere length change of the whole cells and morphologic change of bone marrow cells. It is concluded that analysis of telomere length by flow-FISH manifests the significance for monitoring disease conditions, estimating prognosis and guiding therapy in all kinds of leukemia. The simultaneous analysis of telomere length and cell surface antigen by multicolor flow-FISH may monitor abnormal clone or clonal evolution to predict recurrence more sensitively and specifically, and may provide a promising and widely applicable method for monitoring MRD in leukemia.
