Objective To investigate high risk factors associated with cervical intraepithelial neoplasia (CIN) in married women aged 25 to 54 years in Beijing. Methods From Mar. 2007 to Sep.2008, 6339 married women at age of 25 to 54 years were selected randomly by cross sectional survey in a total of 137 communities of 12 districts or counties in Beijing. The interview was carried out with unified questionnaires, gynecological examination. The cervical smear cytology and high-risk human papillomavirus (HR-HPV) infection of cervical secretion were detected. Women with abnormal cervical cytology underwent colposcopy and cervical biopsy. Odd ratio (OR) and 95% confidence interval (CI) of related high risk factors with CIN were studied by logistic regression analysis. Results Among 6339 women, the prevalence rate of CIN including 4 squamous cell carcinoma (SCC) was 5. 90% (374/6339). By multinomial regression analysis, HR-HPV infection (95% CI: 9. 953 - 15.811 ), History of trichomonas vaginitis (95 % CI: 1. 046 -2. 104), oral contraceptives (95% CI: 1. 087 - 1. 806), age less than 45 years old ( 95% CI: 1. 069 -1. 828) were related with CIN. Conclusion Infection rate of HR-HPV is an independent risk factor of CIN, however, the history of trichomonas vaginitis, oral contraceptives and age less than 45 years old are related risk factors of CIN.

BACKGROUND:Hematopoietic reconstruction of malignant tumor in hematopoietic system is related to disease itself,pretreatment program and therapeutic tool after transplantation;especially,mobilization.collection and cryopreservation of auto-peripheral blood stem cell play a key role in successful reconstruction of hematopoietic system after transplantation.OBJECTIVE:To investigate the reconstruction of hematopoietic system through mobilization, collection and cryopreservation of auto-peripheral blood stem cell in patients with malignant tumor and analyze the effective factors on quantity and quality of auto-peripheral blood stem cell.DESIGN:Case analysis based on malignant tumor in hematopoietic system.SETTING:Department of Blood,Guangzhou General Hospital of Guangzhou Military Area Command of Chinese PLA;Department of Blood,Zhujiang Hospital,Nanfang Medical University.PARTICIPANTS:A total of 18 patients with malignant tumor in hematopoietic system were selected from Department of Blood,Guangzhou General Hospital of Guangzhou Military Area Command of Chinese PLA.Their ages ranged from 1 6to 56 years.Among them,2 patients had acute myelogenous leukemia(AML),1 acute lymphoblastic Ieukemia(ALL),2 lymphoblastic Ieukemia (LL),2 chronic granulocytic leukemia(CGL),4 multiple myeloma(MM),and 7 non.Hodgkin lymphoma.Granulocyte colony-stimulating factor(G-CSF)was made by Chugai Pharmaceutical Company Limited (batch number:N3G31).METHODS:①All patients were mobilized with associated chemotherapy+G-CSF.Associate chemotherapy:Patients with leukemia were given 2 g/m2 arabinosyl cytosine every 12 hours from lhe first to the third days and 200 mg/m2 etoposide or 50 mg/m2 fludarabine from the first to the fifth days. In addition patients with MM were treated with arabinosyl cytosine as the same way mentioned above and with 1 g/m2 cyclophosphamide from the first to the second days. And patients with lymphoma were given 2 g/m2 cyclophosphamide from the first to the second days. When numbers of leucocyte of all patients decreased below 1.0×109L-1 after chemotherapy.G-CSF started mobilization and the collection was stopped with 5μg/(kg·d)subcutaneous injection.②When numbers of leucocyte increased to (4.0-10.0)×109 L-1,hemopoietic stem cells of peripheral blood were collected till the amount of mononuclear cells≥4.0×108/kq or numbers of CD34+ cells≥2.0×108/kg.And then,the samples were dealt with cooling device.maintained in liquid nitrogen at-196℃ and defrosted in water bath at 37-40℃.③Focal sites of patients were pretreated with local irradiation with 200 cGy/time and 5 times/week for 4 successive weeks.The total dosage was 40 Gy.At 48 hours later,(55.3±28.7)mL hemopoietic stem cells of peripheral blood were transfused back. And the duration from transfusion to collection was about(56.5±22.3)days.300 μg/d G-CSF was subcutaneously injected into all patients at 1 day after transplantation and the reaction was stopped at the phase of neutrophil≥0.5×109L-1. Finally. Refusing-staining rate of trypan blue of peripheral blood stem cell, amount of mononuclear cells, number of granulation-monophyly progenitor cell colony and percentage of CD34+ cells were detected before and after thaw.MAIN OUTCOME MEASURES:①Collection of auto-peripheral blood stem cell;②survival rate and related markers of auto-peripheral blood stem cell after cryopreservation;③hematopoietic reconstruction of auto-peripheral blood stem cell after transplantation.RESULTS:All 18 patients with malignant tumor in hematopoietic system were involved in the final analysis.The mean collection time of auto-peripheral blood stern cell was 12.6 days after chemotherapy.the collection times were 1.9.total number of leucocyte was(8.93±1.27)×1 0.L-1 on the first day,and collection rate of mononuclear cell was (138.33±28.61)%. ②Refusing-staining rate of trypan blue of auto-peripheral blood stem cell was similar before and after cryopreservation[(96.26±1.33)%, (92.75±2.04)%,P＞0.05].in addition,after cryopreservation,recovery rates of mononuclear cells,CD34+ cells and granulation-monophyly progenitor cell were(91.96±1.37)%, (85.94±0.64)%and (87.69±4.53)%,respectively.Collection rate of mononuclear cells,number of granulation-monophyly progenitor cell colony and percentage of CD34+ cells were lower in patients with myeloma than in those with leukemia and lymphoma (t=2.524-3.268.P＜0.05).③At 15 days after transplantation,15 patients had the neutrophil≥0.5× 109L-1;at 20 days after transplantation,blood platelet was≥20 × 100 L-1.granulation-monophyly progenitor cells[(18.67-26.82)× 105/kg] of 5 patients grew poorly if the course of chemotherapy was more than 10 times.Among them,3 patients had delayed hematopoietic reconstruction after transplantation of auto-peripheral blood stem cell.CONCLUSION:①High-dose chemotherapy combined with G-CSF can shorten collection time of peripheral blood stem cell and improve collection rate of mononuclear cells.②Increase of chemotherapy times before transplantation can affect quantity and quality of auto-peripheral blood stem cell and cause delayed hematopoietic reconstruction.

Glioblastoma is carcinogenesis of glial cells in central nervous system and has the highest incidence among primary brain tumors. Brain metastasis, such as breast cancer and lung cancer, also leads to high mortality. The available medicines are limited due to blood-brain barrier. Abnormal activation of phosphatidylinositol 3-kinases (PI3K) signaling pathway is prevalent in glioblastoma and metastatic tumors. Here, we characterized a 2-amino-4-methylquinazoline derivative XH30 as a potent PI3K inhibitor with excellent anti-tumor activity against human glioblastoma. XH30 significantly repressed the proliferation of various brain cancer cells and decreased the phosphorylation of key proteins of PI3K signaling pathway, induced cell cycle arrest in G1 phase as well. Additionally, XH30 inhibited the migration of glioma cells and blocked the activation of PI3K pathway by interleukin-17A (IL-17A), which increased the migration of U87MG. Oral administration of XH30 significantly suppressed the tumor growth in both subcutaneous and orthotopic tumor models. XH30 also repressed tumor growth in brain metastasis models of lung cancers. Moreover, XH30 reduced IL-17A and its receptor IL-17RA in vivo. These results indicate that XH30 might be a potential therapeutic drug candidate for glioblastoma migration and brain metastasis.
