Objective To study the efficacy of CPT-11 TACE in the treatment of unresectable HCC.Methods A retrospective review was undertaken on unresectable HCC patients receiving doxorubicin transarterial chemoembolization (59 cases) and irinotecan(CPT-11) in 24 cases from May 2003 to November 2011.Survival analysis was performed with Kaplan-Meier statistics.Differences in survival between the two groups were assessed for statistical significance with the log-rank test.Results Overall survival time was significantly longer in patients treated with CPT-11 compared with doxorubicin treated group (21.7 vs 14.5 months,P =0.042).There was no significant difference in time to progression between the two groups,but time to progression was longer in CPT-11 group than doxorubicin treated group (11.42 vs 9.46 months,P =0.091).Subgroup analysis showed that for intermediate-stage HCC,CPT-11 resulted in a significantly longer time to progression and overall survival compared with doxorubicin treated group (P =0.029 and P =0.014,respectively).There were no significant differences in adverse events among the two groups (P ＞ 0.05).Conclusions Chemotherapeutic agent CPT-11 in the form of TACE significantly improved overall survival when compared with doxorubicin for the treatment of unresectable HCC.

Objective To evaluate the efficacy of chemoradiotherapy in patients with unresectable pancreatic cancer who were previously treated with PTCD.Methods From September 2005 to December 2012,47 unresectable pancreatic cancer patients with obstructive jaundice were enrolled in this study.They were divided into two groups.21 patients received after PTCD chemotherapy or radiation,or chemoradiotherapy.26 patients in support care group received only nutrition,analgesia and other related support treatment.Survival analysis was performed with Kaplan-Meier statistics.Differences in survival between the groups were assessed for statistical significance with the log-rank test.Results The median overall survival time of patients after PTCD was 7.19 months.The median overall survival time of chemoradiation group was 9.07 months,which was higher than that of support care group (5.52 months),P=0.017.12 patients received single therapy (either chemo or radiation),and 9 patients received chemoradiotherapy.The median overall survival times were 8.31 months and 11.15 months,respectively (P =0.325).Conclusions Post PTCD chemoradiotherapy helps prolong the survival time in unresectable pancreatic cancer patients.

To study the cost-effectiveness of temozolomide combined with radiotherapy in the treatment of glioblasto-ma. Methods:According to the clinical trial data, cost-effectiveness and sensitivity of the results was analyzed based on the domestic cost and consumption level. Results:Temozolomide combined with radiotherapy could prolong one month of overall survival with the additional cost of RMB 58 959. 7 yuan in each case when compared with radiotherapy alone. Conclusion:Temozolomide combined with radiotherapy has no advantage on cost-effectiveness when compared with radiotherapy alone.

Background and purpose:Progranulin (PGRN) is a novel growth factor that plays an important role in the tumorigenicity, tumor cell migration and cell cycle. Its expression in many malignant tumor cells is high. It is not only involved in tumor cell growth, but also closely related with the occurrence and evolution of tumor. This study was to investigate the expression of PGRN in gastric cancer and the effects on proliferation and senescence in gastric cancer cell line BGC823. Methods:Immunohistochemical method was used to detect the expression of PGRN in gastric cancer tissues and adjacent normal tissues; Quantitative real-time polymerase chain reaction (qRT-PCR) was used to detect the expression of PGRN in PGRN-siRNA BGC823 cells;MTT method, cell colony formation and cell senescence experiments were used to explore the effects of PGRN on proliferation and senescence in BGC823 cell. Results:PGRN protein levels were high in gastric cancer tissues;Knocking down the PGRN gene in BGC823 decreased the proliferation and clonogenic capacity, cloning efifciency in PGRN-siRNA group was (25.3±3.1)%, in the control group was (72.1±5.7)%, and in the normal cells was (80.3±4.0)%, there was no signiifcant difference between normal group and control group, but there were signiifcant differences among PGRN-siRNA group and the other two groups (P<0.05);Knocking down the PGRN gene in BGC823 cells could promote cell senescence. The positive rate of aging in PGRN-siRNA group was (27.6±2.1)%, in the control group was (3.2±1.3)%, and in the normal group was (1.9±1.2)%, there was no signiifcant difference between normal group and control group. But there were signiifcant differences among PGRN-siRNA group and the other two groups (P<0.05). Conclusion:PGRN can be used as a new marker for gastric cancer, and provide new ideas to the treatment of gastric cancer.

Objective To improve the effects of health education(HE)and satisfaction degree on HE of inpatients by executing hierarchical full-responsibility nursing. Methods Fourteen wards were randomly chosen form the hospital and divided into the control group and the experimental group, each group having 7 wards. The control group carried out routine holistic nursing model, and the experimental group carried out a new hierarchical full-responsibility nursing system. Reforming nursing scheduling and diminishing the nursing unit to assure that the patients acquired the continous and stable nursing service when they were in hospital. The effect and the degree of satisfaction of HE were compared between two groups after 6 months. Results The effects of HE in the experimental group were significantly better than those in the control group, and the degree of satisfaction on HE in the experimental group was much higher than in the control group. Conclusions The hierarchical full-responsibility nursing system can give patients systematic and normalized HE. It can significantly improve the effects and the degree of satisfaction on HE.

Objective:To study interferon alpha (IFN-α) inhibition of proliferation and apoptosis induction of human brain vascular adventitial fibroblasts(HBVAFs)via IFI16.Methods:Cultured HBVAFs were treated with transfection IFI16 siRNA and/or IFN-α in vitro instantaneously.The protein and mRNA levels of IFI16,P53,P21 were measured by Western blot and Real-time PCR.MTT was used to detect the cell proliferation of the HBVAFs.Cell cycle and apoptosis were analyzed by flow cytometry.Results:IFN-α with terminal concentration of 2 000-5 000 kU/L induce significantly expression of IFI16 in HBVAFs,without any significant difference.Stimulated with 2 000 kU/L IFN-α up-regulated the expression of P53,P21 at protein and mRNA levels,and inhibited the cell proliferation and promote cells apoptosis in HBVAFs.Such effect was restrained by transfection with IFI16 siRNA into HBVAFs.Conclusion:IFN-α inhibits HBVAFs proliferation and induces apoptosis may partly relate to the increased IFI16 expression.
