Objective To observe the effects of health promotion on tumor recurrence,quality of life and self feeling evaluation of patients with superficial bladder carcinoma.Methods 104 patients with superficial bladder carcinoma treated in our hospital from March 2002 to March 2005 were divided to two groups randomly.The patients in one group were treated by bladder irrigation with Bacille Calmette Guerin (BCG)simply,and those in the other group were treated by bladder irrigation and health promotion.Tumor recurrence,quality of life and self feeling evaluation between the two groups were compared.Results All patients were foUowed up for 7.3-36.0 months(mean 28.5 months).17 patients(15/51)in the simple BCG irrigation group had tumor recurrence in 0-12 months(2 patients),13-24 months(6)and 25- 36months(9)respectively.The recurrence rate in the first year was 3.9%.in the second year 11.8% and in the third year 17.6%.Eleven(11/53)patients had in the BCG irrigation and health promotion group.in 0-12 months(2),13-24 months(7),and 25-36 months(2)respectively.The recurrence rate in the first year was 3.8%.in the second year 13.2%.and in the third year 3.8%.There were no significant differences in the recurrence rates of the first and second year between the two groups(P>0.05).but there was significant difieFence in the recurrence rate of the third year between the two group(Y2=5.29,P< 0.05).There were no significant difierences in self feeling SCL-90 evaluation and quality evaluation of life after the first discharging between the two groups(P>0.05).After 3-year follow up,the life quality of the patients in the BCG irrigation and health promotion group was improved obviously compared with the simple BCG group(X2=6.47,P<0.05),and the bad negative emotion was diminished obviously compared with the simple BCG group(P<0.05).Conclusion Health promotion after operation on the patients with superficial bladder carcinoma can decrease the long-term tumor recurrence rate obviously,and improve the quality of life and self feeling significantly.

Pyroptosis is a new way of programmed cell death,a number of researches have found that it is associated with a variety of diseases.Inflammasome and caspase protein family play key roles in regulating pyroptosis.Intracellular pattern recognition receptor oligomers under external stimulus,then assemble with apop-totic speck-like protein containing a caspase recruitment domain and caspase precursor into inflammatory com-plex body,thus activation of caspase can induce pyroptosis.While as the upstream regulation mechanism of pyroptosis,inflammasome might be double edged swordfor tumor growth.On the one hand,inflammasome can inhibit the proliferation of tumor cells by inducing pyroptosis;on the other hand,the cumulative effect of the inflammsome can also form a suitable microenvironment for tumor cells and promote tumor growth.

OBJECTIVE: To observe the influence of Xiaotan Sanjie Recipe on growth of the transplanted tumor and expressions of proliferating cell nuclear antigen (PCNA) and epidermal growth factor receptor (EGFR) in tissue of the gastric carcinoma of nude mice, and to explore the mechanism of Xiaotan Sanjie Recipe in restraining the multiplication of the stomach cancer. METHODS: MKN-45 gastric carcinoma model in nude mice was established. Forty-five nude mice were randomly divided into control group, Xiaotan Sanjie group and 5-fluorouracil (5-FU) group. Drugs were given on the next day of inoculation. Mice in the control group were given normal saline, and mice in the Xiaotan Sanjie group were given Xiaotan Sanjie Recipe. Intraperitoneal injection of 5-FU was administered in the 5-FU group. The expressions of PCNA and EGFR were examined by using streptavidin peroxidase (SP) conjugate technique, and the tumor weight and pathological characteristics were also observed. RESULTS: Compared with the control group, Xiaotan Sanjie Recipe significantly restrained the growth of the transplanted tumor, and reduced the expressions of PCNA and EGFR in tissue of the gastric carcinoma of nude mice (P<0.05). CONCLUSION: Xiaotan Sanjie Recipe can disturb the synthesis of DNA and reduce the proliferous activity of cancer cells by decreasing the expressions of PCNA and EGFR.

Objective To investigate incidence,risk factors and the prevention strategy of local recurrence 6 months after surgery for metastatic bone tumors.Methods Data of 797 patients who had undergone operations for metastatic bone tumors from March 1997 to March 2012 were retrospectively analyzed.Sixty-three patients (7.9％) who had local recurrence 6 months after operation were enrolled in the recurrence group,including 40 males and 23 females,and the average age at the time of operation was 55.21 years.Seven hundred thirty-four patients were enrolled in the non-recurrence group,including 432 males and 302 females,with an average age of 56.49 years.The risk factors for local recurrence 6 months after operation for metastatic bone tumors were statistically analyzed.Results The statistical analysis showed the risk factors for local tumor recurrence 6 months after surgery for metastatic bone tumors included preoperative general condition (10.9％ vs 6.2％),the rate of progress of the primary tumor (10.1％ vs 6.1％),site of bone metastasis (9.1％ vs 3.9％),surgical method (11.4％ vs 6.4％),whether local radiotherapy was performed preoperatively (28.0％ vs 6.6％),whether local radiotherapy was performed postoperatively (8.7％ vs 2.8％),whether sensitive systemic therapy was performed preoperatively (12.2％ vs 6.1％),whether sensitive systemic therapy was performed postoperatively (10.3％ vs 5.6％) and whether local therapy was performed in primary tumor site (10.1％ vs 5.8％).Multivariate analysis showed the independent risk factors included preoperative general condition (OR=0.534),rate of progress of the primary tumor (OR=2.164),site of bone metastasis (OR=2.906),whether local radiotherapy was performed preoperatively (OR=3.184),whether sensitive systemic therapy was performed preoperatively (OR=2.344) and whether sensitive systemic therapy was performed postoperatively (OR =0.468).Conclusion When the patients has following conditions:poor preoperative general condition,fast progressive primary tumor,metastatic tumor in the axial skeleton,application of local radiotherapy preoperatively,and application of sensitive systemic therapy,the surgical treatment should be chosen cautiously.

Dedifferentiated chondrosarcoma(DDCS)comprises approximately 10%of all chondrosarcomas and has the worst outcome with a 5-year survival of 10%.The preferred localizations are the femur,humerus and pelvis.DDCS represents a special form of chondrosarcoma characterized by the presence of well-differentiated cartilaginous component in juxtaposition with malignant mesenchymal tumor of high-malignancy grade.The diagnosis of DDCS is highly complicated,requiring detailed radiological and histopathological evaluation as well as precise bioptic technique.The dedifferentiated component is typically a high-grade sarcoma(usually grade 3 or 4),which can be either an osteosarcoma,a malignant fibrous histiocytoma or an anaplastic spindle cell sarcoma.In approximately one-third of the radiographs,one-third of the MR images,and one-half of the CT scans, the tumors demonskates bimorphic features.Recently,array-based comparative genomic hybridization(array-CGH)studies have been performed on frozen chondrosarcoma(including DDCS)specimens.There is a statistically significant association between high-grade tumor(grade Ⅲ and dedifferent ated)and the recurrent genetic deletions at 5q14.2～q21.3,6q16～q25.3,9p24.2～q12,and 9p21.3.One of the most commonly deleted regions of DDCS involved chromosome 9.Earlier investigations of DDCS showed p53 mutation and p53-LOH in the anaplastic component.It is also accompanied by Rt-LOH.P161NK4 and E-cadherin promotor methylation were observed in the low grade chondroid compartment of DDCS.While p161NK4,FHIT,and E-cadherin were methylated in highly malignant osteosarcomatous compartment of the tumor.Surgical resection of the tumor within wide or radical margins is the most important treatment.The value of neoadjuvant or adjuvant therapy remain uncertain.Several new drug targets have been identified and phase Ⅱ studies are currently ongoing.Current phase Ⅱ trials open for DDCS patients used the following medicine:apomab(proapoptotic selective agonist of Ap02L/TRAIL death receptor),perifosine(serine/threonine kinase Akt inhibitor),dasatinib(multitargeted small-molecule tyrosine kinase inhibitor),and the combination of gemcitabine and docetaxel.More recently,several phase Ⅰ studies have reported incidental responses of DDCS to newer targeted agents,such as histone deacetylase and vascular endothelial growth factor antisense oligodeoxynucleotide.The prognosis for patients with DDCS remains poor. The poor prognosis of the DDCS is determined by nonchondroid high grade component caused by invasive growth and formation of metastases.Therefore,early diagnosis and prompt surgical treatment may improve the outcome.
