BACKGROUNDTo identify the relationship of cervical cancer with pathogen infectious, cytokine and Se.

METHODSOn the one hand regarded tissues of the carcinoma of the uterine cervix with 195 cases as the experimental group and ordinary cervical tissues with 75 cases as the control group. Polymerase chain reaction (PCR) to detect them. On the other hand applied ELISA to detect cytokine IL-2R, TNF and fluorescent luminosity technique to detect element Se in the serums.

RESULTSIn the experimental group those infected pathogen were 166 cases (85.1%), In all of pathogen HPV 16,18,35 type were 60 cases (30.8%), HSV 2 were 60 cases (30.8%), While those ordinary tissues infected pathogen were 15 cases (20 0%),in the contrast group. HPV 16,18,35 type and HSV 2 mere 4.0% and 6.7% respectively,(P<0.001). In the serums of effective 62 experimental objects IL-2R (x=356.44 U/ml) and TNF (x=373.48 pg/ml) were much high than them in the serums of effective 36 contrast objects (P<0.001). But Se (x=0.058 mg/ml) was lower than it in the serums of contrast objects (P<0.05).

CONCLUSIONSThe occurrence of carcinoma of the uterine cervix is closely connected with infection of HPV 16,18,35 and HSV2, high level of cellular factors IL-2R, TNF and low level of element Se.

OBJECTIVE: To explore the genetic basis for a fetus with club foot detected upon mid-pregnancy ultrasonography. METHODS: Amniotic fluid of the fetus and peripheral blood samples of its parents were collected and subjected to G-banding karyotype analysis and copy number variation sequencing (CNV-seq). The result was verified by fluorescence in situ hybridization (FISH). RESULTS: The fetus and its parents all had a normal karyotype. CNV-seq analysis revealed that the fetus has harbored a 23.12 Mb on chromosome 5 and a 21.46 Mb duplication on chromosome 7. FISH assay has verified that its mother has carried a cryptic t(5;7)(p14.3;q33) translocation. CONCLUSION CNV-seq combined with FISH can effectively detect cryptic chromosome aberrations, and can help to reduce severe birth defects and provide a basis for prenatal genetic counseling.
