1.Efficacy evaluation criteria for immunotherapy in solid tumors
Journal of International Oncology 2016;43(11):848-851
Immunotherapy has become an important therapy for solid tumors,which is in addition to surgery,radiotherapy,chemotherapy and targeted therapy.However immune treatment mechanism is different from those previous treatment.The effect of immunotherapies is on the immune system and not directly on the tumor.The kinetics of immunotherapy is characterized by a cellular immune response followed by potential changes in tumor burden and survival period.They are not captured by the traditional World Health Organiza-tion (WHO)or the Response Evaluation Criteria in Solid Tumors (RECIST).New immune-related response criteria are defined which more comprehensively capture all response patters and gradually applied in clinical practice.

BACKGROUND:Different embolic materials can be used for bronchial artery embolization in patients with pulmonary tuberculosis hemoptysis. Sodium alginate microspheres and gelatin sponge are two commonly used materials; however, there are relatively few related reports about the comparative analysis on the application effect of these two materials. OBJECTIVE:To investigate the clinical efficacy of sodium alginate microspheres for bronchial artery embolization on pulmonary tuberculosis hemoptysis. METHODS:Totaly 157 patients with pulmonary tuberculosis hemoptysis, including 98 male and 59 female patients, aged 22-75 years, were enroled and subjected to bronchial artery embolization using different embolic materials: sodium alginate microspheres group (n=74) and gelatin sponge group (n=83). During the 12 months of folow-up, the clinical curative effect, recurrence and complications condition of these two groups were observed. RESULTS AND CONCLUSION:The total effective rates of sodium alginate microspheres and gelatin sponge groups were respectively 91.19% and 81.93%, and there was a significant difference between groups (P < 0.05). The recurrence rates of sodium alginate microspheres and gelatin sponge groups were respectively 6.8% and 26.5%, and there was a significant difference between groups (P < 0.05). Additionaly, there was no significant difference in the complications between groups (P > 0.05). These results demonstrate that sodium alginate microspheres for bronchial artery embolization has a better result in the clinical treatment of pulmonary tuberculosis hemoptysis with a high clinicaly effective rate and low recurrence rate.

Objective To investigate the feasibility and efficacy of combined preoperative chemora- diation program followed by radical surgery in bulky early or moderate uterine cervical cancer.To determine the incidence and predictive value of rasidual disease in the radical hysterectomy specimens after CCR. Methods Thirty-five patients with uterine cervix carcinoma from January 2001 to September 2003 were treated with preoperative external beam radiotherapy to 3060 cGy in 4 weeks.Patients received concurrent continuous infusion cisplatin(20 mg/m~2)on day 1,8,15,22 of four weeks and 5-Fu(4 g)chemotherapy during the first four days and the last four days of the radiation course.Radical surgery was not performed until 4 weeks after the completion of the preoperative treatment.Results Clinical response was 85.71%,complete response,54.29 %;partial response,31.43 %.The analysis of the surgical specimens showed 19 patients had revealed residual disease and 16 patients had revealed no residual disease,the complete pathological response hed been 45.71%.Three-year survival rate was 87.14 % in 35 patients.Three-year survival rate of residual disease patients(76.32 %)was significantly lower than that of no residual disease(100.0 %)(P=0.0358). Three-year survival of cervical stromal invasion less than 1/2 and invasion extra stromal was 100.0 %, 41.67 % respectively(P=0.0109);three-year survival of lymph-vascular space involvement and no lymph- vascula space involvement was 0,85.29 %,respectively(P=0.0148).Conclusion Combined preoperative chemoradiation program followed by radical surgery in bulky early or moderate cervical cancer could reveal an effective efficacy with a tolerant complication.Residual disease is an independent and strong predictive factor.

To explore the regulation of eIF4E, we screened the protein interacting with eIF4E from human cDNA library by using yeast two-hybrid system. Several clones interacting with eIF4E were identified. One of them was homologous with HUWE1 (HECT, UBA and WWE domain containing 1, also named as ARF-BP1, HECTH9 or HUWE1). Cell co-immunoprecipitation showed that eIF4E could bind to HUWE1 in mammalian cells. We also found that HUWE1 bearing the HECT domain is necessary for its association with eIF4E.

Xenotransplantation is a feasibility way of solving the shortage of human organs for transplantation. Although it is urgently needed to satisfy the demand of people and sustain the function of human organs, there are multiple hurdles existed to clinical application, such as the immune rejection between human body and the xenografts, the infection of pathogens and a series of ethic, morality and social issues. A historical retrospect of xenotransplantation was given, and then probe into the strategies according to the main problems and the actualities. Finally, the prospect in the field of xenotransplantation was showed.

Objective To investigate the relationship among methotrexate(MTX) plasma concentration,dosage,clinical effecicy and toxicity, and to evaluate it′s clinical significance.Methods MTX was measured by a flurorescence polarization immunoassay in plasma samples obtained from acute lymphoblastic leukemia(ALL) patients treated in different doses of MTX, and these results were analyzed combined with clinical manifestations.Results 1.The average of plasma concentration at 24 hours increased with the increasing doses of MTX. The relapse rate decreased with increased plasma concentration;2.The cerebrospinal fluid(CSF) concentrations prior to the intrathecal MTXinstillation were all below the effective concentration, so the intrathecal MTX instillation was needed;3.No severe toxicity was observed in the study, because the plasma concentration was below the high risk.Conclusion The study of MTX plasma concentration provides us an objective basis for the individualized chemotherapy.
