OBJECTIVE: To investigate the stability of 0.5% glutaraldehyde solution. METHODS: Classic constant temperature accelerated test method and sample observation method were applied with the content of glutaraldehyde as index. The content of glutaraldehyde was determined by titration which was determined by titration. RESULTS: The content change of 0.5% glutaraldehyde solution was in line with the first order kinetics, and the results of both methods were similar. The validity duration of 0.5% glutaraldehyde solution was 85.7 days at room temperature (25 ℃). CONCLUSION: 0.5% glutaraldehyde solution should be used up as soon as possible and the perfect time is less than 2 week.

Aim To study the effects of ginsenoside-Ro on cell proliferation and cytokine production in murine splenocytes. Methods The effect of ginsenoside-Ro on murine splenocytes proliferation was studied using [3 H] thymidine incorporation assay. Effects of ginsenoside-Ro on the production of cytokines interleukin-2 (IL-2), interferon-γ (IFN-γ) and interleukin-4 (IL-4) from murine splenocytes were detected by ELISA method. Effects of ginsenoside-Ro on mRNA level of Th1 cytokine IFN-γ and Th2cytokine IL-4 were evaluated by reverse transcription polymerase chain reaction (RT-PCR) analysis.Results Ginsenoside-Ro showed no mitogenic effect on unstimulated murine splenocytes. It enhanced the proliferation of Con A-induced murine splenocytes and the production of IL-2 at concentrations of 1 - 10decreased the production and expression of Th1 cytokine IFN-γ in Con A-induced murine splenocytes at regulating the production and expression of Th1/Th2 cytokines in murine splenocytes.

BACKGROUND: Idiopathic scoliosis is a common spinal deformity in teenagers, which is managed mainly by orthomorphia. However, due to great trauma, long operative duration and large blood loss, a great amount of blood transfusion is needed during the surgery. Allogeneic blood transfusion should be reduced in order to release blood insufficient, decline blood transfusion expense, as well as avoid transfusion diseases. OBJECTIVE: To investigate the value of controlled hypotension combined with autotransfusion in idiopathic scoliosis orthomorphia.METHODS: Intraoperative controlled hypotension was performed during posterior orthomorphia surgery on all the 46 cases of idiopathic scoliosis, 17 cases in which were served as the control group, who underwent allogeneic blood transfusion without autotransfusion, while the other 29 cases were served as the experimental group, who underwent autotransfusion that including reinfusion of preoperative deposited autologous blood and intra-operative salvaged autologous blood. The blood loss volume and transfusion status in two groups were observed. RESULTS AND CONCLUSION: Blood loss volume in the control group was 400-1 000 (867±161) mL, and that in the experimental group was 350-1400 (842±376) mL, There was no marked difference between the two groups (P > 0.05). The volume of allogeneic blood transfusion in the control group was 500-1 800 (845±332) mL, which was greater than that in the experimental group [0-1 300(423±237) mL] (P < 0.01). The results suggested that controlled hypotension reduces intraoperative bleeding, and postoperative autotransfusion minimizes the need of allogeneic blood transfusion.

Purpose To explore the immunohistochemical features of neuroendocrine markers, CKpan and TTF-1 and their relationship to TNM stage and prognosis in small cell lung cancer (SCLC). Methods The expression of NSE, CgA, Syn, CD56, TTF-1 and CK-pan in SCLC tissue specimens were detected using immunohistochemical EnVision indirect method. Clinical data and TNM stage of 90 patients were collected and the overall survival ( OS) was followed up by telephone. Results Of 90 cases of SCLC, the vast majority were occured in the elderly men. The ratio of man to woman was 5 to 1. The median age was 64 years old. The stageⅠ+Ⅱ was 21 cases, 30 in stageⅢand 39 cases in stage IV. The positive rate of immunohistochemical staining of neuroendocrine markers for NSE, CgA, Syn and CD56 were 83. 3%, 70%, 65. 5% and 86%, respectively. The positive rate of CKpan, TTF-1 were 92. 2% and 81. 1%. Kaplan-Meier analysis indicated that the expression of TTF-1 and NSE were significantly correlated with the TNM stage and over-all survival of patients with SCLC (P<0. 05). The median OS was 8 months in positive expression of TTF-1, which was higher than those in negative expression of TTF1 (5. 5 months)(P=0. 000). The median OS was 7 months in NSE positive expression which was lower than those in negative expression of NSE (11 months)(P=0. 009). The median OS of stageⅠ+Ⅱ,ⅢandⅣwere 16 months, 9 months and 4 months with significant difference ( P=0. 000 ) . Cox multivariate analysis indicated the TTF-1 expression and TNM were independent prognostic factors for the OS of the SCLC patients. Conclusion Most of SCLC has neuroendocrine differentiation, expression CKpan and TTF-1. The expression of TTF-1 may be negative correlation but NSE positive correlation with the prognosis of SCLC patients. And the TTF-1 expression and TNM may be independent prognostic factors for the OS of the SCLC patients.

Objective To analyze the survival and prognostic factors in the treatment of angiosarcoma. Methods A retrospective study was performed on clinical data of 30 patients pathologically diagnosed with angiosarcoma who were admitted to our hospital from 1988 to 2015 and had complete follow?up data. In those patients, 18 patients received comprehensive treatment, containing 9 patients treated with surgery plus radiotherapy, 4 patients with surgery plus chemoradiotherapy, and 5 with surgery plus chemotherapy;12 patients received non?comprehensive treatment, containing 11 patients treated with surgery alone and 1 patient radiotherapy alone. The survival rates were calculated using the Kaplan?Meier method and analyzed using the log?rank test. The Cox regression model was used for multivariate prognostic analyses. Results The 1?, 2?, and 5?year sample sizes were 29,26, and 18, respectively. The 1?, 2?, and 5?year overall survival ( OS) rates were 70?1%, 49?1%, and 40?9%, respectively;the 1?, 2?, and 5?year local relapse?free survival rates were 52?8%, 44?0%, and 35?2%, respectively;the 1?, 2?, and 5?year distant metastasis?free survival rates were 81?6%, 68?0%, and 56?7%, respectively. The multivariate analysis showed that tumor site, tumor size, staging, and visible tumor residue after initial treatment were prognostic factors for OS ( P= 0?027, 0?027, 0?011, 0?000 );In the patients with stage Ⅰ or Ⅱ disease, the comprehensive treatment achieved a significantly lower local?relapse rate than the individual treatment ( P=0?006);gender, age, staging, and tumor site were prognostic factors for distant metastasis ( P=0?028, 0?011, 0?015, 0?022 ) . Conclusions Early diagnosis and early treatment are recommended for angiosarcoma, which has high local recurrence and distant metastasis rates. Comprehensive treatment ( surgery plus radiotherapy and/or chemotherapy) is recommended for patients with stage Ⅰ or Ⅱ disease. Tumor site, tumor size, staging, and visible tumor residue after initial treatment are prognostic factors.
