Objective To observe the expression of breast cancer resistance protein(BCRP) gene in breast cancer patients,and to explore its value in evaluating the therapeutic effect of chemotherapy for breast cancer.Methods Semi-quantitative reverse-transcription polymerase chain reaction(RT-PCR) was applied for the detection of mammary BCRP gene expression level in 60 female breast cancer patients who have received chemical therapeutic regimen of CEF(cyclophosphamide,epirubicin and 5-fluorouracil).The patients were divided into two groups according to the BCRP gene expression before CEF therapy.After treatment,the therapeutic effect in the two groups was observed and the BCRP gene expression level was also measured.Results In 17(17/60,28.3%) patients with positive BCRP gene expression,11 were relieved,with a relief rate of 64.7%,lower than 93.0% in patients with negative BCRP gene expression(P

; 3. therapy with A&A (A&A); 4. Astragali alone (A); 5. Astragali polysac-charide Ⅰ (APⅠ); 6. AP Ⅱ ; 7. Astragali glucoside (AG), Results The level of serum albumin,albumin mRNA and albumin gene transcription were measured by biochemistry, Northern blot hybridization, nuclear run-on assay and quantity in laser density screening. The level of serum albumin in N was significantly lower than C. The serum albumin concentration in each therapy group was higher than N group. The transcription of the albumin gene was higher in N than in C and highest in A&A. The alterations of northern blot hybridization were same as the transcription results. But both the level of albumin mRNA and the transcription of albumin gene in A, AP I , AP I and AG were no change compared with N. Conclusion A&A increases albumin mRNA expression at least in part by improving the rate of gene transcription, which participate the protection of the decrease of serum albumin in NS. But the effect of A, AP 1 , AP I and AG may mediated by other unknown mechanisms.

Standards of TCM information plays a fundamental and critical role in TCM informatization. In recent years, the standardization of TCM information has made a series of tremendous progress. This article introduced the major work progress of TCM terminological standardization and TCM data standardization in China, and status of TCM information standardization in International Organization for Standardization and World Health Organization. The existing problems in the construction of standardization of TCM information were discussed and suggestions were proposed to solve problems: to build the basic framework of standard system of TCM information; to cultivate professionals for the researches on the international standards of TCM information; to further explore the theories and methods about standardization of TCM information.

This study analyzed the current clinical terminology standardization, systematization research status of traditional Chinese medicine(TCM). The previous version of the TCM clinical term system had some problems including imperfect classification structure, unclear relationship between concepts and so on, which made the TCM clinical terminology system(TCMCTS) difficult to support the clinical practice of TCM. The suggestions for system improvement were using ontology method to build TCMCTS concept model bases on the previous researches and data extracted from TCM clinical electronic medical record, and top-level-ontology accordance with ISO standards. The study also tried to summarize the ‘semantic network between classes’ through semantic relationships.

Objective To explore the genetic prenatal diagnosis method for acbendroplasia (ACH).Methods During May to November 2007, three ACH pedigrees were diagnosed at the Prenatal Diagnosis Center, Department of Obstetrics and Gynecology, Affiliated Drum Tower Hospital of Medical College, Nanjing University. In family 1, there was a 6-month-old male ACH infant. In family 2, the expectant mother, with 18 weeks of pregnancy, was an ACH patient. Amniocentesis was performed for prenatal diagnosis. The fetus of family 3 was diagnosed as ACH by ultrasound examination on the 39th week of gestation. Umbilical cord blood of this fetus was collected for examination. Totally, three methods, restriction enzyme (Sfc Ⅰ and Msp Ⅰ ) digestion analysis, denaturing high performance liquid chromatography (DHPLC) and sequencing analysis were performed simultaneously to detect the pathogenic mutation of flbroblastic growth factor receptor 3 (FGFR3) for the three ACH families. Results ( 1 ) The DHPLC detection: heteroduplex was detected in the patient of family 1 ; beth the patient and the fetus of family 2 showed heteroduplex results; the result of the fetus of family 3 was also heteroduplea. (2) The enzyme digestion analysis for the PCR products of 10 exon of FGFR3: after Sfc Ⅰ digestion, the PCR products of patients and the fetus of family 1 and 2 showed not only the band of 247 bp, but also bands of 162 bp and 85 bp. But their PCR products could not be digested by Msp Ⅰ , and it only showed the band of 247 bp. For the fetus of family 3, the PCR products could not be digested by Sfc Ⅰ , while after digestion by Msp Ⅰ , bands of 162 bp and 85 bp were shown up. The PCR products of the normal control could be digested by neither Sfc Ⅰ nor Msp Ⅰ. (3) The sequencing results: the heterozygote mutation of 1138 C→A was confirmed in the patient of family 1. The pregnant woman and her fetus in family 2 showed the same result. The heterozygote mutation of C→C was confirmed in the fetus of family 3. The site of 1138 was G homozygote in the normal control The three detection results of the fetus in family 2 were the same as that of the mother, which means that the fetus inherited the same pathogenic mutation from his or her mother. Conclusions Both DHPLC and restriction enzyme digestion analysis could detect the mutation of FGFR3 gene, but DHPLC is more rapid, convenient and sensitive. So DHPLC can be applied to genetic diagnosis and prenatal diagnosis for ACH patients.

Objective To investigate the relationship between the infiltration of lymphocytes in renal tissues and podocytes injury in patients with lupus nephritis (LN),and provide the evidence of mechanism of podocytes injury in LN.Methods Thirty cases of biopsy proven LN patients were enrolled into the study,10 cases were selected as a the controls.The clinical and pathological data and renal tissues were collected.The infiltration of T lymphocytes (CD4+,CD8+ cells) and B lymphocytes (CD20+ cells) in renal tissues were detected by immunohistochemical method.The nephrin expression was detected by immunofluorescence.The relationship between CD4+,CD8+,CD20+ cells in renal tissues and 24 h UP,nephrin expression were analyzed by Pearson's correlation analysis,respectively.Results ① Compared with the control group,the 24 h UP was increased [2.86±1.37 vs 0.10±0.22 (g/24 h)];the infiltrations of inflammatory cells were increased significantly,the podocytes injury could be observed,combined with effacement of podocytes foot processes or disappeared in the LN group.Moreover,the increase of 24 h UP of active LN group was more evident than that in the inactive group [3.91 ±1.45 vs 1.77±0.69 (g/24 h),F=24.15,P＜0.05],and the infiltration of inflammatory cellsand effacement of podocytes foot processes were more severe in the active LN group.②Compared with the control group,the nephrin expression decreased and the infiltration of CD4+,CD8+ and CD20+ cells in the renal tissues increased significantly,which was mainly aggregated in renal interstitial tissue.And In addition,CD4+ [98±13 vs 40±12 (cells/glomerulus),F=240.18,P＜0.05],CD8+[109.0±16.4 vs 53.3±12.1(cells/glomerulus),F=210.40,P＜0.05] and CD20+ [149.4±1.4 vs 82.6±13.3 (cells/glomerulus),F=544.30,P＜0.05] cells of the active LN group were more remarkable than that in the inactive group.③ The Pearson correlation analysis showed that CD4+,CD8+ and CD20+ cells in renal tissues were positively correlated with 24 h UP (r=0.688,0.748,0.702;P＜0.01),and were negatively correlated with nephrin expression (r=-0.623,-0.793,-0.693;P＜0.01).Conclusion The infiltrations of CD4+,CD8+ and CD20+cells in renal tissues are very closely related with podocytes injury in patients with LN,and the infiltration of lymphocytes may be an important mechanism for podocytes injury in LN patients.
