Objective To investigate the rationality and prognostic value of the Criteria for clinical staging of esophageal cancer treated by non-surgical methods (Draft) by comparison with the criteria for postoperative pathological staging.Methods A retrospective analysis was performed on the clinical data of 162 patients with esophageal cancer who underwent radical resection at the Second Hospital of Soochow University from December 2008 to July 2012.Preoperative clinical staging and postoperative pathological staging were performed,and the Kappa statistic was used to evaluate the agreement between the two staging systems.The Kaplan-Meier method was used to calculate overall survival (OS) rates,and the log-rank test was used for survival difference analysis and univariate analysis.Results The coincidence rates of T,N,and TNM stages were 67.9％,57.4％,and 67.9％,respectively,and the agreements were moderate,poor,and moderate,with Kappa values of 0.544,0.302,and 0.509.The follow-up rate was 93.2％.The 1-,2-,and 3-year sample sizes were 127,66 and 27,respectively.The 1-,2-,and 3-year OS rates were 82.6％,56.2％,and 37.7％,respectively.There were no significant differences in OS between patients with preoperative T1 and T2 stages and between patients with preoperative N0 and N1 stages (P =0.086,0.101),but significant differences were observed between patients with different T stages,N stages,or TNM stages (P =0.000-0.028).This was in line with the prognostic results based on the postoperative pathological staging.Conclusions The clinical staging criteria (draft) have moderate agreement with the criteria for postoperative pathological staging and have good prognostic value,but they require further refinement and improvement.

Objective Alzheimer's disease(AD) is a common and devastating disease and there is no readily available biomarker to aid diagnosis or to monitor disease progression. This study is to further understand the pathogenesis of Alzheimer's disease and seek new biomarkers for AD. Methods AD rats made by Aβ1-40 were assessed using the Morris water maze method. Sera of two groups were collected and albumin, IgG and sodium chloride were removed from the serum before concentration. Two-dimensional electrophoresis(2-DE) was performed on serum protein. Altered proteins were identified by matrix assisted laser desorption/ionization time of flight mass spectrometry(MALDI-TOF-MS). Results Compared with untreated samples, 10 altered proteins were found through 2-DE and all of them were down-regulated of which 2 were identified by MALDI-TOF-MS to be plasma retinol-binding protein precursor and complement component 4, gene 2 (C4b). Conclusion C4b may be the biomarker of AD and it may be helpful to understand the pathogenesis of AD.

The 23 cases with chronic myelogenousleukemia (CML) were treated with program ofharringtonine and ara-c (HA) and the results werethat the 13 cases got complete remission and 10cases got partial remission. Comparing with thecontrol group the patients of which were treatedwith busulfan, the authors found that the spendedtime of decreased WBC in blood (WBC decreasedto 10. 0 ? 10~9/L) and reduced spleen (reduced tosmallest status of spleen) and improvement of self-sensation symptoms in the group treated with HAwere better than those in control group. The HAprogram for cases who recured CML again and re-ceived maintenance cure after remission of CMLwas still effective. The time of maintenance cureand interval should be individualized.

Objective To study the characteristics and the related risk factors of coronary artery changes in the elderly patients of coronary heart disease complicated with diabetes mellitus. Methods According to WHO diagnostic standards of diabetes, coronary heart disease(CHD) complicated with diabetes mellitus(65 patients) was indicated as CHD+DM group, and the coronary heart disease without diabetes(68 patients) was indicated as CHD group. All patients were examined by coronary angiographic semiquantitative(CAG), and blood pressure, oral glucose tolerance test, level of blood sugar, insulin, lipid, BUN and Cr were measured. The coronary artery changes were analysed by CAG, and the severity of coronary artery stenosis were evaluated by AHA standards. The related risk factors in coronary artery disease were analysed by pluralism straight line statistics. Results The coronary multivessel changes(75 4% vs 38 2%, P

Objective To investigate the relative activity of multidrug resistance P-glycoprotein in the plasma of breast cancer patients, analyze the expression of P-glycoprotein before and after chemotherapy and evaluate its clinical value. Methods The plasma of patients and chemical reagents were mixed and distributed into the 96-well plate. The plate was read at 340 nm absorbaace before and after reaction. The variation of absorbance for each well was calculated, and then relative activity of each sample was compared to the referent compound activity. The relative activity of over 30 % was taken as positive expression of the P-gp for each sample. Results The frequency of P-glycoprotein expression was significantly increased from 16.2 % before chemotherapy to 43.2 % after chemotherapy (P<0.05). The positive expression of P-glycoprotein before and after chemotherapy were 5/6 and 9/16, respectively, in patients with positive lymph node metastasis, and 1/6 and 7/16, respectively, in patients with negative lymph node metastasis. Conclusion The results of this preliminary study suggest in P-glycoprotein expression in plasma of patients play an important role in the selection of drugs, which may be useful to evaluate the prognosis for treatment of breast cancer patients.

Objective To observe the effects of different quantities of cake-separated moxibustion on blood cells and immunoglobulin in immunosuppressive rabbits; To study the possible mechanism of quantity-effect difference. Methods Immunosuppressive rabbit model was established by intraperitoneal injection of cyclophosphamide. Rabbits were randomly divided into blank group, model group, cake-separated moxibustion 3 Zhuang group, 5 Zhuang group, 7 Zhuang group.Liuwei Dihuang Decoction was used to make herbal-cake, and was put on Shenque (RN8), Guanyuan (RN4), and other acupoints, once for every other day, 10 times in total. Venous blood was taken on the next day after finishing treatment, and the contents of blood cells series and IgG, IgM, complement C3 and complement C4 were detected.Results Compared with blank group, the levels of WBC, NEU, RBC, HGB, HCT, PLT, IgG, IgM, and complement C3 of model group significantly decreased, while the levels of LYM and MONO significantly increased (P<0.01). Compared with model group, the increase of HCT and IgM in the cake-separated moxibustion 3 Zhuang group was not significant, the levels of WBC, NEU, RBC, HGB, HCT, PLT, IgG, IgM, and complement C3 in all treatment groups significantly increased, and LYM and MONO significantly decreased (P<0.01). Compared with cake-separated moxibustion 3 Zhuang group, the levels of WBC, IgG, and complement C3 of cake-separated moxibustion 5 Zhuang group significantly increased, and the levels of WBC, HGB and complement C3 of cake-separated moxibustion 7 Zhuang group significantly increased (P<0.01).Conclusion Cake-separated moxibustion can improve the immune function under immunosuppressive state induced by cyclophosphamide, and different quantities have differences in efficacy.

Aim To evaluate the effect of intermedin (IMD)on cell proliferation and regeneration in rat tu-bular epithelial cell line (NRK-52E)that was subjec-ted to hypoxia-reoxygenation (H/R)injury.Methods The NRK-52E cells were divided into control group and three model groups (H/R,H/R +primitive vec-tor,H/R +IMD vector).The content of LDH was de-tected to observe the influence of IMD on H/R injury. The cell proliferation was detected by MTT.The cell cycle was detected by flow cytometry.Real-time PCR and western blotting were used to determine mRNA and protein levels.Results ① In comparison to the con-trol,H/R treatment decreased the cell viability and in-creased LDH activity (P <0.01 );in contrast,com-pared to H/R,IMD treatment ameliorated cell viability (79.1 5 ±1 .421 % vs 61 .22 ±1 .63%,P <0.05)and decreased LDH activities by 33.85% (P <0.01 ).②The proliferation of NRK-52E cells was significantly in-hibited by H/R treatment.In comparison to the con-trol,H/R treatment of NRK-52E cells increased the proportion of cells in the G0 /G1 phase but decreased the proportion of cells in the S and G2 /M phases. Moreover,the over-expression of IMD resulted in S and G2 /Mphase redistribution and the accumulation of G2 /M-phase cells.The real-time PCR and western blotting results indicated that the mRNA and protein expression levels of cyclin D1 ,CDK4 and p57 were increased in H/R-treated cells.IMD further stimulated this up-reg-ulated expression of cyclin D1 ,CDK4 and decreased the expression of p57 in NRK-52E cells.④Cyclin D1 had a predominantly nuclear localization in NRK-52Ecells,although cytoplasmic localization was also ob-served.Conclusion The study shows that the over-expression of IMD may promote renal cell proliferation and regeneration after renal tubular cell H/R injury via the up-regulation of cyclin D1 ,CDK and the down-reg-ulation of p57.
