Objective To study the anti-tumor effect of Zhongjiefeng Injection in vitro and its combination with adriamycin.Methods MTT assay was adopted to determine the in-vitro anti-tumor effect,IC50 was used to measure the direct anti-tumor effect,and Jing' s formula was applied to analyze the combination of the drugs.Results Zhongjiefeng Injection can inhibit the proliferation of Bel 7402(human hepatoma cells),HCT-8(human colon cancer cells),and the IC50 was 33.13 mg/mL for Bel 7402 and 52.39 mg/mL for HCT-8 respectively.Zhongjiefeng Injection at the concentrations of 3.125,6.25,12.5 mg/mL showed an efficancy potentiation action with doxorubicin on the inhibition of HCT-8 cells in vitro,and 25,50 mg/mL showed a synergic effect on HCT-8 .Conclusion Zhongjiefeng Injection has a certain in-vitro inhibitory effect on the growth of Bel 7402 and HCT-8,its combination with doxorubicin in vitro can produce synergic effects(a simple combined or enhanced effects)to HCT-8 cells,especially high concentrations of Zhongjiefeng Injection with doxorubicin.It is suggested that Zhongjiefeng Injection in the doubled dosage may have a better synergistic effect with doxorubicin in clinical treatment of colon cancer.

AIM: To study the effect of Zhongjiefeng Injection(Herba sarcandrae) on mouse liver cancer H_22,and its activities on gastric cancer SGC-7901 in vitro,to find out its influence on the cell cycle. METHODS: By injecting H_22 tumor cells in vivo into mice to check its inhabition on entity and ascites tumor.MTT colorimetric method was used to study the anti-tumor activity on gastric cancer SGC-7901,then we calculated its IC_50 and applied the flow cytometry(FCM) to detect its influence of cell cycle. RESULTS: The rates of inhabition on H_22 entity tumor with three concentrations were 29.8%,36.2%,40.5%,and was the remarkable different from the model group(P

Objective To evaluate dendritic cell vaccine immunotherapy in postoperative colorectal cancer patients. Methods 40 colorectal cancer patients were divided into two groups. Group A was not treated with the dendritic cell vaccine after chemotherapy, Group B was treated with four courses of autologous dendritic cell vaccine. The level of cytokines was tested before and after the therapy in both groups. DTH were tested after the last course of treatment. Results The levels of cytokines significantly increased in group B after vaccination compared with that in group B before vaccination and that in group A.8 patients were DTH positive in 15 patients that were tested after the vaccination. The PTS (progression-free survival) was 22 months in group B compared with 17 months in group A. The recurrence of the disease was not observed in patients with DTH positive. Conclusion DC vaccine in postoperative colorectal cancer patients improves the immune status and elicits tumor-specific response.

Objective To investigate the prognostic value of red cell distribution width (RDW) and relationship between RDW and severity of critical illness patients and prognostic role of RDW.Methods This was a prospective observational and diagnostic test study.From February 2011 to May 2013,196 medical patients in ICU were enrolled to study.Blood samples were taken within 24 hrs after admission to ICU for blood routine test and other chemical routine test,including RDW.Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE Ⅱ) score were also calculated.The patients were divided into survival group (n =126) and death group (n =70) based on their hospital outcomes.Differences in RDW levels and APACHE Ⅱ score between survival and death groups were compared with One-way ANOVA.The correlation between RDW and APACHE Ⅱ score were analyzed by Spearman correlation test.Receiver operator curve (ROC) test was used to determine the predictive value of RDW and APACHE Ⅱ for hospital death.Results Both RDW level and APACHE Ⅱ score were significantly higher in death group than those in survival group,whichwere (13.35 ±2.21) vs.(11.34 ±1.32) and (20.43 ±6.41) vs.(13.94 ±6.77) respectively (both P ＜ 0.01).RDW significantly correlated with APACHE Ⅱ score (r =0.309,P ＜0.01).To predict hospital death area under curve (AUC) of ROC curve by RDW and APACHE Ⅱ score were 0.792 (0.725,0.860) and 0.754 (0.686,0.822) respectively.The best cut-off value was determined by Yoden Index were 12.35 for RDW and 17.5 for APACHE Ⅱ score.The Accuracy of prediction was 76.5％ and 70.4％ respectively.In addition,all the 12 paticnts whose RDW level ＞ 15.4 were dead.Conclusion RDW level at admission to ICU correlate well with the severity of critical illness.RDW level has an additional predictive value for the prognosis of critical ill patients.

Objective To investigate the correlation between 28-day prognosis and red cell distribution width (RDW) in sepsis patients.Methods This was a prospective observational study.Two hundred and thirteen sepsis patients were consecutively selected,and the patients were divided into 2 groups according to RDW:normal RDW group (RDW ＜ 0.15,160 cases) and high RDW group (RDW≥0.15,53 cases).The general conditions,acute physiology and chronic health evaluation (APACHE) 1Ⅱ score,sequential organ failure assessment (SOFA),hypersensitive C reactive protein (hs-CRP),procalcitonin (PCT),arterial blood lactic acid,liver function injury,renal function injury and 28-day mortality were compared between 2 groups.The independent risk factors of 28-day prognosis were analyzed by multifactor Logistic regression analysis.Kaplan-Meier survival analysis was used to draw the 28-day survival curve,and the survival rate was compared between 2 groups by log-rank test.Results The 28-day mortality in high RDW group (35.8％,19/53) was significantly higher than that in normal RDW group (17.5％,28/160),and there was statistical difference (P =0.007).RDW ≥0.15 was the independent risk factor of 28-day death in sepsis patients (OR =2.634,95％ CI 1.316-5.273,P =0.006).After adjusted by gender,age and other relative factors,RDW≥0.15 was the independent risk factor of 28-day death in sepsis patients (OR =2.895,95％ CI 1.155-7.252,P =0.023).The 28-day accumulative survival rate in high RDW group was significantly lower than that in normal RDW group (50.5％ vs.63.0％),and there was statistical difference (P =0.014).Conclusion The high RDW in sepsis patients is the independent risk factor of 28-day death,and RDW ≥0.15 shows an important predictive value in the prognosis of sepsis patients.

To study the anti-tumor activity of Scurrula parasitica polysaccharides (SP). Water extraction and ethanol precipitation were used to isolate SP from S. parasitica leaf. S180, K562 and HL-60 cell lines proliferation inhibition by SP were detected by MTT assay. The expressions of Ki-67, Cyclin D1, Bax and Bcl-2 protein in the sarcoma S180 tissues were detected by immunohistochemistry technique to approach the anti-tumor mechanism of SP+ SP could not inhibit cancer cell proliferation. SP ip could inhibit the growth of sarcoma S180 in mice, 100 mg x kg(-1) x d(-1). SP ip was the optimal dose on inhibiting S180 growth, with the tumor inhibition rate of 54%. The expression of Ki-67, Cyclin D1, Bax and Bcl-2 protein in the sarcoma S180 tissues were detected by immunohistochemistry technique to approach the anti-tumor mechanism of SP. The result showed that SP could down-regulate the expression of Ki-67, CyclinD1 and Bcl-2 protein, and up-regulate the expression of Bax protein. It indicted that inhibiting cancer cell proliferation and promoting cancer cell apoptosis in vivo maybe one of the anti-cancer mechanisms of SP.
