Objective To explore the cytotoxicity of the cytotoxic T lymphocyte (CTL) induced by SW480 sonicate sensitized dendritic cells (DC) on the colon cancer cell line SW480. Methods PBMC were separated from the HLA-A*0201 donor and DC were cultured with rhGM-CSF, rhIL-4 and rhTNF-α. The same donor's primary CTL were stimulated by DC loaded with SW480 sonicate. The cytotoxicity of CTL on SW480 (HLA-A*0201 positive) and K562 (HLA-A*0201 negative) was determined by the MTT method. Results The cytotoxicity of the CTL on SW480 was stronger than that on K562 (P ＜0.05). Conclusion The DC vaccine can stimulate specific CTL which can trigger cytotoxic activity on the target cells and this cytotoxicity is related to MHC restriction.

Objective:To assess the advantages and nursing experience of foley catheter for nephrostomy tube after minimally invasive percutaneous nephrolithotomy (mPCNL).Methods:From October 2015 to April 2016,the clinical data of 137 patients,who were diagnosed with upper urinary tract calculi and need to perform mPCNL,were collected and randomized into 2 groups:a foley catheter group (research group,n=69) and a normal nephrostomy tube group (control group,n=68).The patients in research group used foley catheter for nephrostomy tube,while those in the control group used normal nephrostomy tube.Bleeding volume,the days of bleeding,pipes shedding and pain degree were compared,and the experience of the nursing process was summarized.Results:The bleeding volume,the days of bleeding in the research group were significantly lower than those in the control group (both P＜0.01).The pipes shedding rate in the research group were lower than that in the control group (P＜0.05).There was no significant difference in postoperative pain scores between the 2 groups (P＞0.05).There was no other complications and discomfortable symptoms in the experimental group.Conclusion:The use of foley catheter for nephrostomy tube after mPCNL is safe,and it can decrease the bleeding volume and pipes shedding rate.It doesn't increase the patient's postoperative pain and can reduce the difficulty and risk for postoperative nursing.

[Objective] This study was designed to determine Th1, Th2 cell numbers and investigate T-bet mRNA, GATA-3 mRNA expression of spleen MNC in a mufine asthmatic model which intended to understand effect of airway T-bet plasmid gene transfer on Th differentiation. [ Methods] A mouse asthmatic model was established by sensitization with ovalbumin (OVA). Thirty-two C57BL/6 mice were divided into four groups (8 mice in each group): the normal control group (group A ), the asthmatic model group (group B), the pcDNA3 plasmid group (group C), the pcDNA3-T-bet group (group D). All animals were sensitized and challenged with OVA, except group A normal saline was applied. The group C was intranasally administered 50 μg pcDNA3 plasmid at 24 h before intranasal challenges, and the 50 μg pcDNA3-T-bet plasmid for the mice of group D. We investigated Th1 and Th2 cell numbers by FACS and T-bet, GATA-3mRNA expression of spleen mononuclear cells (MNC) by semi-quantitative PCR in the four groups. [Result] Th1 percent in spleen MNC of pcDNA3-T-bet treated mice was significantly increased ([2.29±1.551% vs. [1.93±1.141%, P<0.05), while Th2 percent was significantly decreased ([0.93±0.64]% vs. [1.63±0.59]%), compared with that of the asthmatic control group mice by FACS. Spleen MNC was detected a high level of T-bet mRNA expression (0.53±0.027 vs. 0.28±0.035, P<0.05) and a low level of GATA-3 mRNA expression (0.24±0.022 vs. 0.58±0.038, P<0.05) after pcDNA3-T-bet treatment by RT-PCR. There was no significant change between the pcDNA3 plasmid group and the asthmatic model group. [Conclusion] The intranasal transfer of pcDNA3-T-bet plasmid was effective in modulating the imbalance of Th1/Th2 in mice asthma model, which provides a novel therapeutic strategy for transferring transcriptional factor in allergic asthma.

AIM: To investigate the effect of T-bet plasmid gene transfer to airway on allergen induced airway inflammation in a murine asthmatic model. METHODS: A mouse asthma model was established by sensitization with ovalbumin (OVA). Forty C57BL/6 mice were divided into 4 groups (10 mice in each group): the normal control group (group A), the asthmatic model group (group B), the pcDNA3 plasmid group (group C), and the pcDNA3-T-bet group (group D). The animals in group B, C and D were sensitized and challenged with OVA. The animals in group A were applied with normal saline. pcDNA3 plasmid at dose of 50 μg was intranasally administered at 24 h before intranasal challenges to the mice in group C, and the 50 μg pcDNA3-T-bet plasmid for the mice in group D. Bronchial alveolar lavage fluid (BALF) was collected and lung tissues were resected at 48 h after OVA challenge for later assay. RESULTS: After administration with pcDNA3-T-bet plasmid, high level of T-bet expression at 48 h was detected in the lung tissue by Western blotting. In pcDNA3-T-bet treated asthmatic models, histological evaluation revealed the significant suppression of eosinophil peribronchial and perivascular infiltration, and reduction of epithelial damage. The numbers of eosinophils, neutrophils and lymphocytes in BALF from pcDNA3-T-bet treated mice were significantly reduced compared to those in asthmatic control group (P<0.05). The level of IL-4 in BALF was significantly decreased in pcDNA3-T-bet group compared to that in asthmatic control group (P<0.05), while the level of IFN-γ in BALF was significantly increased in pcDNA3-T-bet group. No significant change of inflammation cells and cytokines in pcDNA3 plasmid group and asthmatic control group was observed (P>0.05). CONCLUSION: Intranasal pcDNA3-T-bet plasmid transfer inhibits asthmatic airway inflammation in the murine asthmatic model, suggesting a new therapeutic strategy for allergic asthma.

Objective To investigate the effects of postoperative adjuvant chemotherapy (CT) and chemoradiotherapy (CRT) or radiotherapy(RT) for Ⅰ b-Ⅱ a cervical cancer with risk factors.Methods From March 1995 to June 2010,there were 137 patients underwent radical hysterectomy and systematic pelvic lymphadenectomy for stage Ⅰ b-Ⅱ a cervical cancer admitted at Peking University First Hospital.These patients had risk factors,intermediate risk factors including bulky tumor (＞4 cm),lymph vascular space invasion,deep stromal invasion; high risk factors including positive surgical margin,parametrial invasion,lymph node involvement.Of the all patients,79 cases of them were treated with CT,58 of them were treated with RT or CRT.The 5-year survival and prognosis factors were analyzed retrospectively,the prognosis was compared between two adjuvant therapy groups.Results The univariate analysis shown that types of pathology,different grade of risk factors,stroma invasion and lymph node involvement were prognostic factors of 5-year overall survival Patients with squamous cell carcinoma,intermediate risk factors,no parametrial invasion,and no lymph node involvement had better prognosis (P ＜ 0.05).Whether patients with high-risk factors or intermediate-risk factors,the 5-year overall survival and 3-year disease-free survival had no difference between CT and RCT or RT groups respectively.Cox regression multivariate analysis of survival indicated that clinical stages,types of histology,different grade of risk factors were independent prognostic indicator.Patients with early stage,squamous cell carcinoma,intermediate risk factors had better prognosis.Univariate and multivariate analysis indicated that different postoperative adjuvant therapies had no effects on the prognosis.The 5-year overall survival was 88.6％ in patients treated with CT,and 89.7％ in patients treated with RT or CRT (P =0.455).Conclusion There are equivalent therapeutic results between CT and RT or CRT for patients with risk factors after radical surgery,CT may be as one choice of postoperative adjuvant therapy for stage Ⅰ b-Ⅱ a cervical carcinoma with risk factors.
