Objective To investigate the relationship of the metastasis-associated genes and its copy numbers variation in the highly metastatic human epithelial ovarian cancer cell line HO-8910PM. Methods The differentially expressed genes and its copy number variation between HO-8910PM cell line and normal ovarian tissues was detected by human genome UI33A 2.0 gene chip and human mapping 10K array 2.0 gene chip, and the data was analyzed by bioinformatics. Some of metastasis-associated genes were validated the results of single nucleotide polymorphism (SNP) and cDNA chips by fluorescence in situ hybridization (FISH) and real-time quantitative PCR. Results Integrate analysis of two gene chips data showed that there were 385 differentially expressed genes in the same and 379 SNP positional point (6 of them, included 2 genes) between HO-8910PM cell line and normal ovarian tissues, these copy number amplification of 379 SNP positional point of chromosome were ≥3, which had 240, deletion ≤ 1 had 139. Chromosome location analysis showed that there were 385 differentially expressed genes located at all chromosomes, and 261 of them ( 67.8%, 261/385 ) located at 10 chromosomes, included that 34 (8.8% ), 33 ( 8.6% ), 28 (7.3%), 27 (7.0%), 25 (6.5%), 24 (6.2%) of them located at chromosome 3, 2, 9, 10, 1 and 11 respectively, and 23 (6.0%) of them at chromosome 6 and 12 each, 22 (5.7%) of them at chromosome 4 and 5 each. For the function of differentially expressed genes, the results showed that 99 (25.7% ) genes belonged to the family of enzymes and their regulators, 54 ( 14.0% ) genes associated with signal transduction, 50 (13.0%) genes associated with nucleic acid binding, and 36 (9.4%) genes associated with protein binding. Conclusion We have demonstrated that there are 4 kinds of differentially expressed genes related to metastasis of ovarian cancer, which belonged to the families enzyme and its regulator, nucleic acid binding, signal transduction and protein binding, and located at chromosome 1, 2, 3, 4, 5, 6, 9, 10, 11 and 12.

Objective To analyze the serum proteomic pattern of the cervical cancer patients,to develope diagnostic model and to evaluate its clinical significance.Methods WCX magnetic bead and MALDI-TOF were used to detect the serum proteomic pattern of 77 patients with cervical squanmous cell carcinomas,13 patients with CINⅢ and 52 healthy women.Biomarker Wizard software was used to detect protein peaks and potential difference between cervical cancer and controls.The model was developed by Biomarker Patterns software.Results A diagnostic pattern consisting of three differential protein peaks was established with 100%(32/32)sensitivity and 93.8%(30/32)specificity.A sensitivity of 77.8%(35/45)and a specificity of 75%(15/20)in blind test were obtained.The diagnostic model also could discriminate CINⅢ and SCC-Ag negative patients from controls.Conclusion The diagnostic pattern combining 3974,3398,13732m/z protein peaks can discriminate not only cervical squamous cell cancer but also CINⅢ and SCC-Ag negative patients from controls.

OBJECTIVESTo study the difference between gene expressions of high (H0-8910PM) and low (HO-8910) metastatic human ovarian carcinoma cell lines and screen novel associated genes by cDNA microarray.

METHODScDNA retro-transcribed from equal quantities of mRNA derived from high and low metastatic tumor cells or normal ovarian tissues were labeled with Cy5 and Cy3 fluorescein as probes. The mixed probe was hybridized with two pieces of BioDoor 4096 double dot human whole gene chip and scanned with a ScanArray 3000 laser scanner. The acquired image was analyzed by ImaGene 3.0 software.

RESULTSA total of 355 genes with expression levels more than 3 times larger were found by comparing the HO-8910 cell with normal ovarian epithelial cells. A total of 323 genes with expression levels more than 3 times larger in HO-8910PM cells compared to normal ovarian epithelium cells were also detected. A total of 165 genes whose expression levels were more than two times those of HO-8910PM cells compared to their mother cell line (HO-8910) were detected. Twenty-one genes with expression levels > 3 times were found from comparison of these two tumor cell lines.

CONCLUSIONScDNA microarray techniques are effective in screening differential gene expression between two human ovarian cancer cell lines (H0-8910PM; HO-8910) and normal ovarian epithelial cells. These genes may be related to the genesis and development of ovarian carcinoma. Analysis of the human ovarian cancer gene expression profile with cDNA microarray may help in gene diagnosis, treatment and prevention.

Objective: To evaluate the efficacy of Fufang-Xuanju capsule combined with levofloxacin mesylate tablets in the treatment of chronic epididymitis. Methods: A total of 76 patients in the Urology Department of Xiyuan Hospital of China Academy of Chinese Medical Sciences who met the inclusion criteria from December 2016 to February 2019, were divided into treatment group (43 cases) and control group (33 cases). The control group was given levofloxacin mesylate tablets orally. The treatment group was given Fufang-Xuanju capsule based on the control group. Both groups were treated for 4 weeks. Chronic epididymitis symptom index (CESI) was used to evaluate the clinical efficacy by pain score and quality of life score. Results: The total effective rate was 83.7% (36/43) in the treatment group and 63.6% (26/33) in the control group. There was statistically significant difference between the two groups (χ²=4.020, P=0.045). Compared with baseline, the pain scores, quality of life scores and total scores of both groups at 2, 4 weeks after treatment were significantly lower (P<0.01). Two weeks after the treatment, the pain scores, quality of life scores and total scores in the treatment group were significantly lower than those of the control group (F value were 16.132, 9.134 and 23.681, respectively, all Ps<0.01). And 4 weeks after the treatment, the pain scores, quality of life scores and total scores of the treatment group were significantly lower than that of the control group (F value were 28.741, 74.049, 72.483, respectively, all Ps<0.01). Conclusions Fufang-Xuanju capsule combined with levofloxacin mesylate tablets can alleviate the pain of patients with chronic epididymitis, improve the quality of life and improve the clinical efficacy.
