To investigate the role of distribution and phylogeny of phenylethanoid glycoside in medicinal plants of Gesneriaceae, five phenylpropanoid glycosides, acteoside, paraboside B, isonuomioside A, paraboside II, and paraboside III were quantitatively determined in 12 species of Gesneriaceae by HPLC. The existence and content of these compounds were analyzed. The results showed that phenylethanoid glycosides were found in the most of those plants, but the kind of phenylethanoid glycosides varied in different species. Acteoside distribute in most of this plant group, paraboside B, isonuomioside A, paraboside II, and paraboside III were rare in those plants. The results of this study support morphological viewpoint that Trib. Trichosporeae is more developmental than Trib. Didymocarpeae.

This study was aimed to investigate various factors influencing long-term survival in adult AML patients with fusion gene aml1/eto positive. A single institutional retrospective study with long-term follow-up was performed to better define the prognostic factors for AML patients with aml1/eto positive. Newly diagnosed 89 adult AML patients with aml1/eto positive were followed up for 1 to 42 months (median 24 months) from January 2004 to July 2008. Univariate and multivariate analysis of potential factors influencing survival and prognosis were carried out by using Log-Rank and Cox regression method, including sex, age, initial WBC counts, extramedullary leukemic disease, central nervous system leukemia (CNSL), chromosome aberrations, immunophenotype, first induction regimen, chemotherapy course to complete remission (CR), time from induction therapy to CR, negative or positive rate of aml1/eto and allogeneic hematopoietic stem cell transplantation and so on. The results showed that the estimated 5-year overall survival (OS) and relapse-free survival (RFS) were (50.0 +/- 2.3)% and (47.0 +/- 1.9)% respectively in follow-up of 89 patients for 1 - 42 months (mean 24 months). Univariate analysis revealed that initial WBC counts, CNSL, chemotherapy course to CR, time from induction therapy to CR, persistent negative in remission and allogeneic hematopoietic stem cell transplantation were important prognostic factors for long-term surviva1. Multivariate study demonstrated that initial WBC counts, CNSL, CD56 positive, negative or positive rate of aml1/eto, time from induction therapy to CR, persistent negative result of RT-PCR assay in remission and allogeneic hematopoietic stem cell transplantation were all critical factors in relation to OS and RFS. It is concluded that Chinese adult AML patients with fusion gene aml1/eto positive have some different characteristics as compared with patients from other countries, a relatively poor outcome is observed in patients, HSCT should be recommended to adult AML patients.

OBJECTIVETo compare therapeutic effects between unilateral decompression technique only and open decompression technique with fusion and internal fixation for the treatment of lumbar spinal stenosis.

METHODSFrom March 2008 to February 2011, 82 patients with lumbar spinal stenosis were treated with operations, and divided into two groups. There were 13 males and 19 females in group A, with a mean age of (56.31±4.31) years old. The patients in group A were treated with unilateral decompression via fenestration technique only, including 23 patients obtaining single level decompression and 9 patients obtaining two levels decompression. In group B, there were 18 males and 32 females, with a mean age of (57.53±4.28) years old. The patients in group B were treated with open decompressive technique with fusion and internal fixation, including 38 patients obtaining single level decompression and 12 patients obtaining two levels decompression. The VAS of back pain and leg pain, ODI were recorded before and after surgery to evaluate low back pain,leg pain and walking tolerance.

RESULTSAll the patients were followed up, and the duration ranged from 10.9 to 43.4 months,with a mean of 32.8 months. There were no differences in age, stenosis level, VAS of back and leg pain and ODI before surgery between two groups. Compared with the corresponding ones in group B, the operation time, blood loss, hospitalization time,recovery time of routine daily life and finacial expenditure of patients were all shorter or less in group A. There was no statistically difference in complications between two groups.

CONCLUSION"Unilateral decompression via fenestration technique" is a less invasive and more effective decompressive technique for degenerative spinal stenosis without posterior elements damage. It has advantages in operation time, blood loss, hospitalization time, recovery to daily life and financial expenditure. When controlling the operative indications strictly, the technique could be an important procedure for surgical treatment of degenerative spinal stenosis, especially in the elderly population.

The aim of this study was to establish a simple, convenient and efficient method of producing placental-eluted gamma globulin (PEGG) from human placenta, explore its inhibitory effect on the function of T lymphocyte in vitro and graft-versus-host disease (GVHD) in vivo. PEGG was prepared by elution at acid pH from human placental tissues that were extensively washed. Its effects on T lymphocyte proliferation induced by PHA and mixed lymphocyte reaction (MLR) were analysed by BrdU ELISA, its effect on the CD25 and CD69 expression on T cells was observed by flow cytometry, and the interferon gamma (IFN-gamma) and interleukin-4 (IL-4) quantification in MLR supernatant were assayed by ELISA. A murine GVHD model was established, the effect of PEGG on the manifestation and pathologic change of GVHD and 45-day survival rate were observed. The results showed that considerable level of immunoglobulin could be eluted from placenta at acid PH, of which the main components were IgG checked by SDS-PAGE analysis. In vitro study indicated that PEGG significantly inhibited both the proliferative response of T cells to PHA and the MLR, down-regulated the expression of CD25 and CD69 on T cells stimulated by PHA, and decreased the secretion of IFN-gamma but increased the production of IL-4 in MLR supernatant. In vivo, recipient mice treated with PEGG had a markedly increased survival rate with less histopathological evidence of GVHD. It is concluded that PEGG can inhibit the proliferation and activation of T cells, regulate the direction of T helper cells differentiating towards Th2 type, and effectively prevent GVHD in a murine model. In short, PEGG may be a potent therapeutic agent for GVHD.
