This study was aimed to define the scope of traditional Chinese medicine (TCM) informatics standards. The basic construction of three-dimensional profiling framework includes TCM business domain, elements of TCM informationization and specificity level. The clinical informatics standards development was stated as an example to demonstrate the application method of this three-dimensional profiling framework.

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.

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 construct the pcDNA3. 1-Brugia malayi (Bm) glyceraldehyde-3-phosphate dehydrogenase (GAPDH) eukaryotic recombinant plasmid and to study its effect on mouse cellular immunity response. Methods Total RNA was prepared from periodic Bm. The target gene fragments were amplified by reverse transcription-polymerase chain reaction (RT-PCR) technique and then were inserted into the cloning vector. pGEM-T Easy, and sub-cloned into pcDNA3. 1. Purified pcDNA 3. 1-BmGAPDH recombinant plasmid and CpG were injected into the anterior tibial muscle of BALB/c mice in order to induce host immunity response. Mice injected with PBS and mice injected with blank plasmid were prepared as controls. The mouse models were immunized for 3 times with an interval of 2 weeks. RT-PCR was utilized to detect target gene expression in the muscle tissue. MTT method was used to measure the immunized mice T lymphocytes stimulation index, while enzyme-linked immunoassay (ELISA) was used to determine the serum interleukin (IL)-4 and interferon (IFN)-γ level. Means were compared using t test with SPSS software. Results The recombinant plasmid pcDNA3. 1-BmGAPDH was constructed sucessfully. The target gene was 1020 bp long and its homology with known gene sequence in database was 99%. BmGAPDH gene in the injected muscle of the immunized mice was detected by PCR. The proliferation of spleen T lymphocytes was higher in pcDNA3-BmGAPDH group than in the 2 control groups which were 1. 398, 1. 006 and 1. 017,respectively (P< 0. 05). The levels of IFN-γ and IL-4 in serums from the immunized mice were significantly higher than those of the PBS control group and blank plasmid control group which were 163.905, 58.589, 51. 317 and 107. 906, 27.111, 34.627, respectively (P<0. 05). Immune adjuvant CpG could accelerate and boost antigen-specific immune responses induced by vaccine, which presented as significant increase of IFN-γ and lymphocyte proliferation at 4 weeks after immunization.Conclusion The recombinant eukaryotic plasmid pcDNA3. 1-BmGAPDH is constructed and could elicit cellular immune responses in immunized mice.

Objective To analyze the reasons of discarding as useless of ?-Se direct conversion digital flat panel detector (?-Se FPD). Methods (1) E-COM DR-2000CTM chest system, with high frequency X-ray machine made by CPI company of Canada, the X-ray tube made by VARIAN company of America and Direct Ray-1000 ?-Se FPD made by DRC company of America. (2) 50 cases were collected rondomizedly, each had 4 pieces of chest image and were analyzed by two experienced radiologists and two technicians. Results After about 14 months with 30,000 times exposure efficacious, some damage lines and points appeared in the detector. After about 34 months with 70,000 times exposure efficacious, a damage region (area is 6.7in*0.95in ) existed, this reduced the images' quality and at the end the detector was discarded as useless. Conclusion The ?-Se FPD needs maintenance and monitoring working circumstance.

Objective To explore the clinical value of thermal tomography (TT) in the diagnosis of breast diseases.Methods Totally 222 breast diseases patients underwent examinations by color Doppler ultrasound and TT.Some stable TT images were selected,and the TT curves of the lesions were analyzed according to the malignant tumor TT curve diagnosing standard,so that the benign and malignant tumors could be determined.Color Doppler ultrasound was used to describe the site,size and property of the lesion.Results Pathological examination found 95 cases of malignant tumors and 127 benign ones.TT had 198 results coincident with those by pathological examination while the remained 24 ones not,with 15 false positive results and 9 false negative ones.When compared with pathological examination,TT had the accuracy,sensitivity and specificity being 89.19％,90.43％ and 88.28％ respectively.Conclusion TT is non-invasive,accurate and sensitive when used to screen and diagnose breast diseases,and should be applied if possible in medical facilities.
