1.Progress in treatment of acute lymphoblastic leukemia in adolescents
International Journal of Pediatrics 2011;38(1):38-40
The development of effective therapy for children with acute lymphoblastic leukemia (ALL) is one of the greatest successes of clinical oncology. However, cure rates for adults with ALL remain relatively low. Adolescents are the special population between children and adults. These patients group will be received protocol from either pediatric or adult oncologists depending on referral pattern. In recent years, researchers from abroad large cooperative groups show pediatric-based protocol has better outcome than adult-based protocol. In this article, the protocol of ALL in children and adults are compared . It seems the first and probably the most important reason is the dose intensity of the nonmyelosuppressive chemotherapeutic agents, especially asparaginase.

Journal of Chinese Physician 2010;12(2):149-152
Objective To explore the changes of GRO-α and VEGF in the peritoneal fluid of women with endometriosis and their correlation. Methods The levels of GRO-α and VEGF were detected by enzyme linked immunosorbent assay ( ELISA ) method in 39 cases of endometriosis and 25 normal cases of without endometriosis. Results The levels of GRO-αand VEGF in the peritoneal fluid of EMs group were ( 108.77 ± 20. 58 ) pg/ml and ( 199. 67 ± 99. 26 ) pg/ml separately, and it was significantly higher than those in control group ( 71.07 ± 18. 96 ) pg/ml, ( 115.46 ± 32. 39 ) pg/ml. The differences were statically significant( P <0. 05). The level of GRO-α in the peritoneal fluid of the patients in stage Ⅰ and Ⅱ was sig-nificantly lower than that in stage Ⅲ and Ⅳ[(99.43 ± 16.05)pg/ml vs (117.65 ± 20.8)pg/ml, P <0. 05] , while the level of VEGF in the peritoneal fluid of the patients in stage Ⅰ and Ⅱ was significantly higher than that in stage Ⅲ and Ⅳ[(246. 89 ± 114. 34) pg/ml vs ( 152. 82 ± 54. 55 ) pg/ml, P < 0. 05] .There was positive correlation between the level of GRO-α and r-AFS ( r = 0. 439, P < 0. 05 ), but no cor-relation between the level of VEGF and r-AFS ( r = -0. 210, P >0.05). There was no correlation be-tween peritoneal fluid levels of GRO-α and VEGF in the EMs group ( r =-0. 05, P>0. 05). Conclusion Compared with control group, the levels of GRO-α and VEGF in peritoneal fluid of women with endome-triosis were significantly increased, which indicated that the increased GR0-α and VEGF secretion involved in the pathogenesis of this disease. There was correlation between the peritoneal fluid level of GRO-α and the degree of EMs.
5.Relationship between reduced folate carrier gene methylation and methotrexate resistance
International Journal of Pediatrics 2014;41(3):267-270
Tumor recurrence and drug resistance impact patients'therapeutic effect and prognosis seriously.In recent years,it has been found that epigenetic changes are involved in drug resistance.DNA methylation is one of the ways of epigenetic.DNA methylation of drug metabolism enzyme gene can affect gene's expression,leading to drug resistance.Methotrexate(MTX),a folic acid antagonist,is the most widely used drug in the treatment of malignant tumors,such as leukemia,osteosarcoma,head and neck cancer,and so on.Reduced folate carrier(RFC) is the main transporter cartier of MTX,and gene methylation is related to tumor cells'resistance to MTX.This paper reviews the role of RFC,relation of RFC methylation and methotrexate resistance and the factors of RFC methylation.

One hundred and twenty four patients with cervical intra-epithelial neoplasia(CIN group)and 300 women in routine health check(control group)were recruited in the study.Ureaplasma urealyticum(UU)DNA in cervical secretions was detected by fluorescent quantitative PCR(FQ-PCR),and detectopm pf HPV was also performed in 103 CIN cases.The positive rate of UU was 64.5%in CIN group and 38.7%in control group(P<0.05).The results demonstrated that UU infection may be associated with cervical intra-epithelial neoplasia,especially for high-grade lesions;and there may be interaction between UU and HPV infection in development of CIN.
9.Applications of capsular bag model in posterior capsular opacification
Chinese Journal of Experimental Ophthalmology 2016;34(3):276-279
Posterior capsular opacification (PCO),also known as after-cataract,is the most frequent complication and the primary cause for visual decrease after extracapsular cataract surgery.At present,there is no effective way to treat PCO,so more attentions are focused on preventive reseaching of PCO and treatment methods.Although a variety of studies have increased our understanding of the pathogenesis of PCO,the cellular mechanisms responsible for PCO are still unclear.Cultured capsular bag model in vitro could effectively simulate lens capsular membrane and cells survival environment after cataract extraction and IOL implantation.However,lens capsular bag cultivation with different methods have their own characreristics.The material source,preparation methods of capsular bag model,characreristics of materials which maintain capsular bag contours and its application in PCO were reviewed.
