The purpose of this study is to discuss the feasibility of establishing capsaicin pain model and the possibility to evaluate different degrees of pain by the heart rate variability (HRV). It also aims to investigate the changes of autonomic nervous activity of volunteers during the process of pain caused by capsaicin. A total of 30 volunteers were selected, who were physically and mentally healthy, into the study. To assess the effects of capsaicin on the healthy volunteers, we recorded the Visual Analogue Scale (VAS) scores after the capsaicin stimulus. Additionally, the electrocardiogram signals and HRV analysis index before and after stimulating were also recorded, respectively. More specifically, the HRV analysis indexes included the time domain index, the frequency domain index, and the nonlinear analysis index. The results demonstrated that the activity of the autonomic nerves was enhanced in the process of capsaicin stimulus, especially for the sympathetic nerve, which exhibited a significantly differences in HRV. In conclusion, the degree of pain can be reflected by the HRV. It is feasible to establish a capsaicin pain model. And in further experiments, HRV analysis could be used as a reference index for quantitative evaluation of pain.

Objective To explore the efficacy and safety of moderate-dose of etoposide (VP16) with granulocyte-colony-stimulating factor (G-CSF) for mobilization of peripheral blood stem/progenitor cells.Methods VP16 at 1.2 g/m2 was injected intravenously by six divided doses via a central vein, 2 times every 12 hours for 3 days in 31 patients with malignant lymphoma (30 non-Hodgkin lymphoma and 1 Hodgkin lymphoma). All patients received G-CSF 5 μg/kg were given twice daily subcutaneously from the day of the nadir of white blood cell (WBC) till the day before the last APBSC harvest. Results The mean time for the collection of stem cell was 12 days (10-15) following etoposide chemotherapy. The mean number of mononuclear cell (MNC) and CD+34 cells in collection were 7.8×108/kg (5.2-11.3×108) and 7.2×106/kg (5.3-13.1×106). respectively. 18 patients completed collection with a single apheresis, and 13 patients underwenttwice. All patients were recovered for haematopoiesis in following APBSCT. Median (range) time for the recovery of absolute neutrophil count (ANC)>0.5×109/L and platelet>20×109/L were+12 (+9-+18) days and +14 (+10-+21) days respectively. Slight adverse events coursed by the regimen could be tolerated. Conclusion VP16 at moderate dose with G-CSF is an effective and safe mobilizing regimen for autologous peripheral blood stem/progenitor cells in patients with malignant lymphoma. It was suggested to use extensively.

ObjectiveTo investigate the clinical characteristics in ABO-incompatible allogeneic peripheral blood stem cell transplantation(allo-PBSCT).Methods137 patients'clinical courses who accepted allo-PBSCT were retrospectively reviewed. Sixty-five cases of them were ABO-incompatible allo-PBSCT patients,including 32 ABO major mismatched cases,23 ABO minor mismatched cases and 10 ABO major and minor mismatched cases.Seventy-two ABO-identical cases were taken as control group.ResultsCompared with ABO-idential cases,the time of erythrocyte recovery after allo-PBSCT in ABO major and minor mismatched group was delayed [(73.2+10.3) d vs (97.5+10.4) d] (P <0.05).In ABO-incompatible group, the time of blood type switching in different ABO-incompatible types were found no significant difference (P >0.05) [ABO major mismatched:(45.7±17.3) d,ABO minor mismatched:(41.2+16.1) d and ABO major and minor mismatched:(48.4±20.9) d (P > 0.05)].There were 8 cases who have a delayed time of blood type changing, including 6 cases demonstrated recipient-derived anti-A antibody. ConclusionABO-incompatible has no negative effect on allo-PBSCT.The time of erythrocyte reconstitution was delayed in ABO major and minor mismatched group.A delayed time of blood type switching tends to occur in ABO minor incompatible cases and patients who have anti-A antibody initially.

OBJECTIVETo compare the results of extended vertical partial laryngectomy (similar to modified supracricoid partial laryngectomy with cricohyoidoepiglottopexy) and cricohyoidoepiglottopexy in the treatment of laryngeal carcinoma.
METHODSRetrospectively analyzed on the results and prognosis in patients underwent extended vertical partial laryngectomy and cricohyoidoepiglottopexy between 1998 and 2005. The operation was similar to extended vertical partial laryngectomy. The healthy vocal cord and ventricular band as well as about 1/3 to 2/3 laminas of thyroid cartilage were removed. The healthy cricoarytenoid joint was reserved. The vocal cord, ventricular band, fixed or limitation of motion arytenoid cartilage and 2/3 laminas of thyroid cartilage in ill side were removed. The posteroinferior border of laminas of thyroid cartilage in both sides were reserved. The cricoid was lifted and fixed with hyoid epiglottis directly. Extended vertical partial laryngectomy group consisted of 37 patients with glottic carcinoma (stage T2 16 cases, stage T3 21 cases) and cricohyoidoepiglottopexy group consisted of 34 patients with glottic carcinoma (stage T2 12 cases, stage T3 21 cases, stage T4 1 case).
RESULTSKaplan-Meier analysis was performed to calculate the survival rates. The three-year cumulative survival rate was 91.7% in extended vertical partial laryngectomy group and 87.5% in cricohyoidoepiglottopexy group respectively. There was no significant difference between the two groups (P > 0.05). The five-year cumulative survival rate was 80.6% in extended vertical partial laryngectomy group and 81.3% in cricohyoidoepiglottopexy group respectively. There was also no significant difference between the two groups (P > 0.05). The decannulation rate was 100% (37/37) in extended vertical partial laryngectomy group and 94.1% (32/34) in cricohyoidoepiglottopexy group respectively. The decannulation time was (14.0 + or - 2.3) days in extended vertical partial laryngectomy group and (19.0 + or - 4.6) days in cricohyoidoepiglottopexy group respectively. The incidence of aspiration was 2.7% (1/37) in modified group and 23.5 (8/34) in cricohyoidoepiglottopexy group respectively evaluated at 8th weeks post-operatively. The evaluation of deglutition disorder was analyzed by Ridit analysis in both groups and the results showed that there was significant difference between the two groups (U = 7.341, P < 0.001). The symptom of aspiration in extended vertical partial laryngectomy group was significant less than in cricohyoidoepiglottopexy group.
CONCLUSIONSAlthough the survival rate was not different between the two groups. The preservation of laryngeal function in extended vertical partial laryngectomy group was significant better than in cricohyoidoepiglottopexy group and extended vertical partial laryngectomy.

To establish a MacELISA method for the detection of IgM antibodies against Chikungunya virus (CHIKV), we prepared virus like particle (VLP) antigens of CHIKV using the whole structural protein C-E3-E2-6K-E1 encoding gene with a baculovirus expression system in Sf9 insect cells. The VLPs were purified and used to immunize Kunming mice. Then, polyclonal antibodies were purified from the samples of ascites with a protein G HiTrap SP column and labeled with horseradish peroxidase. A MacELISA method for the detection of IgM antibodies against CHIKV was assembled with goat anti-human IgM antibody, VLP antigens and an enzyme-labeled polyclonal antibody. The results were evaluated with a serum panel containing serum samples from laboratory-confirmed CHIK, HFRS patients, healthy donors, and commercially available CHIKV IgM as a quality control. It was shown that the MacELISA had a specificity of 99% (99/100), the coefficients of variation (CoV) within a plate were <10%, and the CoV of different ELISA plates in terms of the plate variation coefficient was <15%. A comparative analysis was performed to compare the current method against a commercial CHIKV IgM antibody detection kit for IIFA-IgM. The detection limit of MacELISA was significantly lower than that of the IIFA-IgM commercial kit (P< 0.0001). Here, we demonstrate that the VLP-based MacELISA is a promising tool for the early diagnosis and epidemiological investigation of CHIKV infection, with a high level of sensitivity and specificity for the detection of IgM antibodies against CHIKV.
