Purpose:To investigate the relationship between cell apoptosis and dephosphorylated RB protein in human breast cancer. Methods:In our work,human breast cell lines (MCF-7/S,the chemosensitive cell line and MCF-7/ADR,the chemoresistent cell line)were evaluated. Chemosensitivity of two cell lines was evaluated by the MTT colorimetric assay;the expressive levels of dephosphorylated RB protein were detected with immunocytochemistry. Apoptosis rates were determined by flow cytometry(FCM). Results:ADR inhibited proliferation of chemosensitive cell line MCF-7/S ,the 50% inhibition concentration (IC 50 ) was 0.128 ?g/ml;And IC 50 of MCF-7/ADR was 10.89 ?g/ml. The chemotherapeutic sensitivity of MCF-7/S was more than that of MCF-7/ADR by 86 times . Before treatment with ADR,phosphorylated RB protein was positive in two cell lines,but dephosphorylated RB protein was negative;After treatment of different concentration ADR,when the concentration of ADR was increased,expression of dephosphorylated RB protein elevated accordingly in MCF-7/S,but no significant change in MCF-7/ADR. Apoptosis and cell cycle was detected by FCM assays shows ADR induced apoptosis of MCF-7/S more than MCF-7/ADR(P0.05).

Aim To investigate effects of glutamate(GLU) and ?-aminobutyric acid(GABA) on levels of neurosteroids synthesized and released by primary cultured rat brain cortical astrocytes.Methods Primary cultured rat brain cortical astrocytes were treated with GLU or GABA for 48 h respectively.Unconjugated(dehydroepiandrosterone,DHEA;pregnenolone,PREG;allopregnanolone,AP) and conjugated neurosteroids(dehydroepiandrosterone sulfate,DHEAS;pregnenolone sulfate,PREGS) in culture media were extracted by solid phase extraction(SPE) and analyzed by HPLC-MS.Results Compared with saline control group,GLU treatment decreased PREG and PREGS levels and increased DHEAS level significantly;GABA treatment decreased PREG level and increased AP level significantly.Conclusion Both GLU and GABA were shown to inhibit the genesis of PREG.While GLU significantly promoted the genesis of DHEAS and GABA promoted the genesis of AP.The genesis of PREGS was also inhibited by GLU treatment in primary cultured cortical astrocytes.

Objective The aim of the current study was to investigate the prognostic value of extracapsular lymph node spread in gastric cancer patients and to find correlations with clinicopathological parameters.Methods Clinicopathological data of 131 gastric cancer patients who underwent gastrectomy with lymphadenectomy were analyzed retrospectively. The number of metastatic lymph nodes with extracapsular spread were determined. Multivariate analysis was performed to find the clinical prognosis affecting extracapsular lymph node involvement. Results Seventy-eight patients (59.5%)had perigastric lymph node metastasis. Fortysix cases were detected extracapsular lymph node involvement. The 5-year cumulative survival rate for patients with extracapsular lymph node spread was 13. 5% , while 32 patients with lymph node metastasis but without extracapsular involvement had a 5-year survival rate of 39.3%. The survival rate decreased significantly with the increase of extracapsular lymph node involvement(P =0.001). Extracapsular lymph node involvement was significantly associated with the higher number of metastatic lymph nodes, the location of lymph node metastasis, tumor invasion depth and distant lymph node metastasis. In the multivariate analysis, extracapsular lymph node spread also remained as an independent prognostic factor(P =0.003). Conclusions Extracapsular lymph node involvement is a convenient and reliable prognostic index, and is an independent prognostic factor in gastric cancer patients. In future staging systems for gastric cancer, extracapsular lymph node involvement should be considered, be pathologically checked and reported in order to determine extracapsular spread status.

Objective To compare the dosimetric difference between RapidArc and fixed gantry angle dynamic intensity modulated radiotherapy (dIMRT) in developing the pre-operative radiotherapy for rectal cancer patients.Methods Two techniques,RapidArc and dIMRT,were used respectively to develop the synchronous intensity modulated plans for 10 stage Ⅱ and Ⅲ rectal cancer patients at the dose of gross tumor volume (GTV) of 50.6 Gy divided into 22 fractions and planning target volume (PTV) of 41.8 Gy divided into 22 fractions.Both plans satisfied the condition of 95% of PTV covered by 41.8 Gy.The dose-volume histogram data,isodose distribution,monitor units,and treatment time were compared.Results The two kinds of dose volume histogram (DVH) developed by these two techniques were almost the same.The conformal indexes of GTV and PTV by RapidArc were better than those by dIMRT (t =7.643,8.226 ,P < 0.05),while the homogeneity of target volume by dIMRT was better (t =-10.065,-4.235 ,P <0.05).The dose of rectum and small bowel planned by RapidArc was significantly lower than that by dIMRT (t =2.781 ,P <0.05).There were no significant differences in the mean doses of bladder and femoral head between these two techniques.The mean monitor units of RapidArc was 475.5,fewer by 48.5% in comparison with that by the dIMRT (924.6).The treatment mean time by RapidArc was 1.2min,shorter by 79.5% in comparison with that by dIMRT (5.58 min).Conclusions There is no significant dosimetric difference between the two plans of RapidArc and dIMRT.Compared with dIMRT,RapidArc achieves equal target coverage and organs at risk(OAR) sparing while using fewer monitor units and less time during radiotherapy for patient with rectal cancer.
