Expression of PRL receptor mRNA in Jurkat D1.1 cell line was confirmed by RT PCR. CD154 expression of Jurkat cells was significantly increased when these cells were incubated with PHA and recombinant human PRL, suggesting that binding of PRL to its receptor promotes CD154 expression which plays a role in immune regulation.

Objective:To investigate the expression of prolactin receptor(PRLr) in human immune system.Methods:Specimens of human immune system were obtained from both central and peripheral immune organs, including thymus(thymoma), bone marrow, lymph node and peripheral blood mononuclear cells. Specific fragments of PRLr mRNA were obtained through RNA isolation and RT-PCR amplification and confirmed by DNA sequencing.Results:PRLr mRNA was detected from the thymoma, bone marrow, lymph node and peripheral blood mononuclear cells. All the PRLr cDNA fragments generated by PCR were as long as the expected length, which was 276 bp. The sequencing result of the cDNA was identical to the sequence of PRLr cDNA in GeneBank.Conclusion:The study confirmed that prolactin receptor mRNA was expressed in human central immune organs such as thymus and bone marrow and peripheral immune organs such as lymph node and peripheral blood mononuclear cells. This phenomenon provided a biologic structural evidence that neuro-endocrine hormone PRL might play a modulating role on immune cells from receptor's point of view.

Objective To observe the cervical regeneration outcome after different loop electrosurgical excision procedures(LEEP) for the management of cervical lesions.Methods A total of 209 patients with cervical lesions including cervical epithelial neoplasia,cervical HPV infection,cervical polyp and condyloma,and severe cervicitis were performed LEEP in our hospital.The types of LEEP included shallow ring excision,deep ring excision,LEEP conization,and that similar to cold-knife conization.The width and depth of removed cervical tissues were recorded,and the cervical regeneration was observed during the follow-up. Results Among the 209 cases,179(85.6%) were satisfactory cervical regeneration,24(11.5%) were little satisfactory cervical regeneration,and 6(2.9%) were unsatisfactory cervical regeneration.Shallow ring excision,deep ring excision and cone excision had higher satisfactory situation.Extroversion of cervical columnar epithelium was observed in 15 cases(7.2%) in little satisfactory cervical regeneration.Severe extroversion of cervical columnar epithelium of 3 cases occurred in unsatisfactory cervical regeneration.Besides,there were 2 case of cervical shortening and 1 case of severe erythema in unsatisfactory cervical regenerations. Conclusion Although having such complications as extroversion of cervical columnar epithelium,cervical shortening and erythema,LEEP performs a high satisfactory cervical regeneration after management of cervical lesions.It is in great need to analyze the condition of different patients in managing cervical lesions by LEEP.

Purpose:To analyze the differences between prem enopausal and postmenopausal female patients with T1 primary breast cancer as to pathological classification, rate of lymphatic metastasis and some relative rec eptors, and to discuss the appropriate mode of operation to T1 breast cancer. Methods:154 patients with T1 primary breast cancer were retrosp ectively divided into premenopausal group and postmenopausal group. The clinical data of the two groups were compared. Results:There were no significant statistical differences in pr imary tumor size, but the incidence rate(62.2%) of invasive ductal cancer in po stmenopausal group was less than that(84.7%) of postmenopausal group(P

Objective To investigate the association between Human Leukocyte Antigen DR (HLADR) gene polymorphisms and total IgE levels in children with asthma.Methods This study involved 84 unrelated children with asthma and 168 healthy controls without asthma.All participants had their serum total IgE levels measured with UniCAP Pharmacia system,and skin-prick test with ten kinds of inhalant allergens were taken among them.HLA oligonucleotide array was used to determine twenty-one gene frequencies of HLADR.Results ( 1 ) The frequencies of HLA-DRB1 * 070X allele and HLA-DRB1 * 11XX allele among the asthmatic were significantly higher than those in the healthy controls (HLA-DRB1 * 070X allele:2.98％vs.0.30％,x2 =6.915,P ＜ 0.05 ; HLA-DRB1 * 11XX allele:13.69％ vs.5.95％,x2 =9.478,P ＜ 0.01 ),Odds ratios( OR)for the two groups were 10.57(95％ CI:1.215 -91.986)and 2.79(95％ CI:1.429 -5.449)respectively.HLA-DRB3( 52 ) * 010X allele were significantly decreased in asthmatics compared to healthy controls(13.99％,x2 =5.854,P ＜0.05),OR was 0.429(95％ CI:0.214 -0.862).(2) Significant correlation between HLA-DRB1 * 160XX,HLA-DRB1 * 3 (17)alleles and the level of total IgE were found in asthmatic children(P ＜0.05).OR were 0.145(95％ CI:0.027 -0.781 )for HLA-DRB1 * 160XX allele and 1.667(95％CI:1.367-2.033)for HLA-DRB1 * 3(17)allele.Conclusion HLA-DRB1 *070X allele and HLA-DRB1 * 11XX allele were implicated in susceptibility to asthma,HLA-DRB3 (52) * 010X allele might conferring protection effects against asthma.There were association between HLA-DRB1 * 160XX,HLA-DRB1 * 3 ( 17 ) alleles and the level of total IgE in asthmatic children.Protective effects of HLA-DRB1 * 160XX allele against high level IgE response was noted,while HLA-DRB1 * 3(17)allele might be associated with high level of IgE in patients with asthma.

Objective To Observe the effects of tumor necrosis factor ? (TNF ?) on cell proliferation and Intracellular free calcium concentraction ([Ca 2+ ]i) in endothelium of human umbilical vein endothelial cells (HUVEC) and investigate the pathogenesis of pregnancy induced hypertension syndrome (PIH). Methods Confluent monolayer of HUVEC was directly incubated with TNF ? at following final concentrations: 500, 1 000, 2 000 U/ml for 24 hours. The percentages of different cellcycles and [Ca 2+ ]i were measured by flow cytometry and fluorospectrophotometry. Results Incubated with TNF ?, the endothelial cells were elongated and transformed into fibroblast like cells. Border of nucleus was sharp, clarity, and cells were in regular shape. But there were abnormal granules in cytoplasma and some cells detached at the concentrotion of 2 000 U/ml of TNF ?. Stimulated by TNF ?, the percentage of cellcycles from phase G 0+G 1 to S and G 2+M decreased significantly and it was dose dependent. [Ca 2+ ]i increased significantly and dose dependent as well. Conclusion TNF ? may injure endothelium directly and inhibit its proliferation and repair through the changes of [Ca 2+ ]i level. It may play an important role in the pathogenesis of PIH.
