Chinese Journal of Obstetrics and Gynecology 2012;47(2):125-128
Objective To explore the clinical value of combined detection of serum human epididymal secretory protein E4 (HF4) and CA125 in the diagnosis of endometrial carcinoma.Methods From Jan 2010 to Apr 2011,the serum specimens were collected from124 cases of endometrial carcinoma,97 cases of benign disease of uterus and 109 cases of healthy women.HE4 levels in the serum were detected by ELISA,and CA125 levels in the serum were detected by the electro- ehemiluminescent immunoassay.Those results were shown with median level.Accuracy of the diagnosis was evaluated by the area under the receiver operating characteristic curve ( ROC-AUC ).ResultsThe median levels of HE4 and CA125 were 78.09 pmol/L and 33.43 kU/L in serum of endometrial carcinoma group.The median levels of HE4 and CA125 were 46.37 pmol/L and 18.26 kU/L in serum of benign disease of uterus group.The median levels of HE4 and CA125 were 31.75 pmol/L and 12.64 kU/L in serum of healthy women group.The HE4 and CA125 levels in serum of endometrial carcinoma group were significantly higher than those of benign disease of uterus group or healthy women group ( all P < 0.05 ).Compared with that benign disease of uterus group,the ROC-AUC of HE4 and CA125 in endometrial carcinoma group were 0.913 and 0.801,respectively.When the specificity was 95.0%,the sensitivities of HE4,CA125,and combined detection of HF4 and CA125 in endometrial carcinoma group were 41.1%,22.6% and 46.0%,respectively.The positive rates of HE4 and CA125 were 31% (27/86) and 12% (10/86) in stage Ⅰ - Ⅱ of endometrial carcinoma,while the positive rates were 63% (24/38) and 47% (18/38) in stage Ⅲ -Ⅳ of endometrial carcinoma,in which there were significant difference between patients in stage Ⅲ - Ⅳ and stage Ⅰ - Ⅱ (P < 0.01 ).ConclusionsThe combined detection of serum HE4 and CA125 is helpful to the diagnosis of endometrial carcinoma.The sensitivity,specificity and early diagnosis of HE4 are better than that of CA125.The positive rates of HF4 and CA125 in endometrial carcinoma are related to the clinical staging.

The serum specimens were collected from ovarian cancer (n =100),benign ovarian disease (n =69) and healthy women (n =95).The serum levels of HE4 and CA125 were detected.Risk of ovarian maliqnancy algorithm (ROMA) was calculated.Accuracy of prediction was evaluated by the area under receiver operating characteristic curve (ROC-AUC).And validity of prediction was evaluated by sensitivity and specificity.The results showed that the median level of ROMA algorithm was 83.0%,8.9% and 8.7% in ovarian cancer,benign ovarian disease and healthy women groups respectively.The difference were statistically significant (all P < 0.01).Compared with benign ovarian disease group,the ROC-AUC of ROMA algorithm was 0.900 in ovarian cancer group.The sensitivity and specificity were 81.0% and 92.8% in ovarian cancer group respectively.Thus ROMA algorithm is a useful parameter in risk stratification for ovarian cancer.The diagnostic accuracy of ROMA algorithm is better than that of HE4 and CA125 in ovarian cancer.

Objective To explore the differences of the proliferation ability and the antineoplastic activity of CIK cells against origenal hepatocellullar cancer cells between healthy adults and tumor patients in vitro. Methods Peripheral blood mononuclear cells (PBMC) from healthy donors and tumor patients were incubated to induce CIK cells in the presence of interferon gamroa(IFN-γ) ,IL-2 and anti-CD3 monoclonal antibody (mAb). The changes in the proliferation activity and phenotypes of the CIK cells were identified by flow cytometric analysis. Single cell suspension was prepared bom the fresh hepatocellular carcinoma tissue by using mechanical trituration method. MTT assays were used to determine the cytotoxicity of CIK cells against origenal hepatocellullar cancer cells. Results The CIK cells from both healthy donors and tumor patients were significantly increased with the extension of time. The expression rate of CD3+/CD56+ cells from healthy donors rose from 1.053% ±0.22% on 1st day ,25.36% ±2.19% on the 7th day to 55.12% ±1.99% on the 14th day ,which was significantly higher than that of tumor patients ( P < 0.05). MTT assays showed that the cytotoxicity of CIK cells from both enhanced obviously with the addition of Effect/Target rate and extension of time(P <0.05). After the origenal hepatocellullar cancer cells were treated by CIK cells 24 hours, the cytotoxicity of CIK cells from healthy donors at the effector:target ratio of 10 ∶ 1,20 ∶1 and 40 ∶1 was significantly higher than that of tumor patients(P<0.05) ,respectively. After treated 48 hours, compared with tumor patients, the cytotoxicity of healthy donors? CIK at the three effector:target ratio was alsosignificantly higher(P <0.05), respectively. Conclusion CIK cells from both have amplification ability and cytotoxic activity in vitro,and the proliferation ability and killing activity of healthy adults CIK is stronger than that of tumor patients,which provides an experimental basis for CIK to clinical application as an adoptive immunotherapy.

Results Among 23 cases, cCD3 was expressed in 10 cases (43.4 %), cCD79a in 16 cases (69.6 %), cMPO in 20 cases (87.0 %), TdT in 14 cases (60.9 %), CD34 in 19 cases (82.6 %) and CD117 in 20 cases (87.0 %). 13 cases (56.5 %) expressed both myeloid and B lymphocyte antigens, in which cCD79a and cMPO were positively expressed, 7 cases (30.4 %) were found to express both myeloid and T lymphocyte antigens of cCD3 and cMPO 3 cases (13.04 %) were positive for both cCD3 and cCD79a. Conclusion cCD3,cCD79a, and cMPO were lineage specific antigen markers, which could be used for diagnosis and differential double phenotype leukemias. FCM is a useful and reliable method for diagnosis of acute leukemia, and guidance of treatment and prognosis of leukemia in clinical.

The individual variability should be considered in precision medicine-prevention and treatment strategies.Medical research using genomics, proteomics, metabolomics, systems analyses, and other modern tools has made big progress.In 2002, the members of the Complex-Trait Consortium proposed to develop a new mouse genetics resource called the Collaborative Cross (CC).The CC is a genetic reference panel of recombinant inbred lines of mice, designed for the dissection of complex traits and gene networks.It will provide a powerful measure for functional studies of biological networks, which will be essential to understand the intricacies of disease processes.

Objective To evaluate the value of angled insonation technique in obtaining the volumes of the fetal palate and in three-dimensional post-processing.Methods Five hundred and sixty-six cases of 20~28 weeks fetuses with normal face were confirmed by systemic ultrasound examinations and post-natal examination.The volumes in the standard midsagittal plane and angled midsagittal plane were obtained,then post-processed these data by 4D-View software.The same technology was used for volume data acquisition and processing to 1 case of cleft lip and palate fetal.Results In 566 fetuses,two groups of volume data were successfully acquired in 458 cases (standard midsagittal plane group) and 411 cases (angled midsagittal plane group).Fetal primary palate in the standard group and the angled group can be both well visualized(100%).Axial plane of hard palate can not be reconstructed in the standard group.Only 36% of the fetal hard palate's coronal plane and transoral oblique coronal plane can be reconstructed.The visualization rate of soft palate was 87% in the standard group,which was slightly higher than the angled group (82%).The visualization rate of hard palate's axial plane,coronal plane and transoral oblique coronal plane was 100% respectively in the angled group.Cleft alveolar process involving the secondary palate can be clearly visualized in 1 case of cleft lip and palate fetus.Conclusions By using the angled insonation technique,which is based on clearly visualizing secondary palate to obtain volumes,using three-dimensional post-processing technique can obtain the conventional three orthogonal planes and any other section of the whole palate.By using it we can assess the integrity of fetal palate,diagnose cleft lip with or without cleft palate and classify the cleft palate,even make prenatal diagnosis of the isolated cleft palate possible.
