Objective To investigate the value of human epididymis secretory protein 4 ( HE4 ) combined with CA125 assay in differential diagnosis of endometriosis cyst and ovarian malignant tumor.Methods The level of HE4 and CA125 were measured by enzyme-linked immunosorbent assay (ELISA) in the serum specimens of 46 cases in endometriosis cyst group,36 cases in malignant ovarian tumor group,60 cases in benign ovarian diseases and 50 women in healthy women group.Those results were shown with median level.The normal range were 0-150 pmol/L in HE4 and 0-35 kU/L,which either one was more than the threshold value defined as positive index.The sensitivity of assay was evaluated by receiver operating characteristic (ROC) curve,the relation and value of HE4 or CA125 alone and combination assay in diagnosis of endometriosis was analyzed by Mann-Whitney U test and correlation analysis.Results (1) HE4:the median levels of HE4 were 52.4,51.0,50.0 pmol/L in group of endometriosis,normal control and benign ovarian tumor,which didn't show statistical difference.However,HE4 was 507.5 pmol/L inovarian cancer group,which was significantly higher than those of 3 groups (P < 0.05 ).(2 ) CA125:there were significant different in median level of CA125 was observed as 743.0 kU/L in ovarian cancer,84.9 kU/L in endoemtriosis,15.4 kU/L in benign ovarian disease,and 11.5 kU/L in healthy women (P < 0.05).( 3 ) The single assay:when compared with that in endometriosis group,receiver operating characteristic area under the curve( ROC-AUC) were 0.933 in HE4 alone and 0.821 in CA125 alone assay in ovarian cancer group.The specificity was 95% and the sensitivity was 79.6% and 49.0%.(4) The combination assay:when compared with those in endometriosis group,the ROC-AUC was 0.936,the specificity was 95% and the sensitivity was 81.0% in ovarian cancer.Conclusions Measurement of HE4 could be used in differential diagnosis of endometriosis cyst.And the combination of HE4 and CA125 assay could discriminate ovarian endometriosis cysts from ovarian malignant tumors effectively.

OBJECTIVETo investigate the effectiveness of surgical strategies for Shang Ring circumcision in the treatment of short frenulum praeputii in patients with redundant prepuce or phimosis.

METHODSTotally, 130 cases of short frenulum praeputii with redundant prepuce or phimosis were randomly assigned to an experimental group and a control group of equal number to receive Shang Ring circumcision, the former by transverse incision in the distal penis foreskin and pull-up of the interior board, and the latter by conventional transverse incision and longitudinal suture of the frenulum praeputii. Comparisons were made between the two groups in the surgical duration, intraoperative blood loss, 24 h postoperative pain visual analog score (VAS), postoperative complications, satisfaction with the penile appearance, and the quality of sexual life.

RESULTSThe surgical duration, intraoperative blood loss, 24 h postoperative VAS, postoperative sexual satisfaction, and satisfaction with penile appearance were (4.60 +/- 1.20) min, (2.61 +/- 1.81) ml, 1.73 +/- 0.76, 98.5%, and 98.5%, respectively, in the experimental group, as compared with (21.60 +/- 6.30) min, (11.10 +/- 3.40) ml, 5.37 +/- 1.84, 70.3% and 69.8% in the control, with statistically significant differences between the two groups (P < 0.05). The incidence rates of such major complications as wound dehiscence, infection, and moderate to severe edema were 1.5% (1/65), 3.1% (2/65), and 4.6% (3/65), respectively, in the experimental group in comparison with 12.3% (8/65), 15.3% (10/65), and 30.7% (20/65) in the control, with statistically significant differences between the two groups (P < 0.05). None of patients had any serious complications.

CONCLUSIONShang Ring circumcision by transverse incision in the distal penis foreskin and pull-up of the interior board, with its advantages of shorter operation time, less blood loss, mild pain, fewer complications, and higher satisfaction and acceptance of the patients, can be used as an safe and effective approach to the treatment of short frenulum praeputii.

Objective To study the dynamic changes of pulmonary lesions of severe acute respiratory syndrome(SARS)treated by non-invasive positive pressure ventilation(NIPPV)on CT. Methods Serial chest CT images in 18 patients with SARS were retrospectively analyzed before and after NIPPV(4—12 days),and a long-term follow-up(3—36 months)examination by CT was carried out.And 27 SARS cases without NIPPV were enrolled as the control group.Results(1)There were dynamic changes in 15 cases of 18 cases:partial multilobar consolidations of bilateral lungs changed into ground-glass opacities in 7 of 18 cases,a circular pulmonary emphysema around bronchial vascular strains of the lower lobes was seen in 5 of 18,subpleural pulmonary emphysema was seen in 8 of 18,pulmonary barotraumas were showed in 2 of 18.Residual of subpleural curvilinear shadow related to NIPPV was found in 2 cases on the follow-up scan.(2)Above changes on CT were not found in 27 cases without NIPPV.Conclusion There were changes of pulmonary lesions of SARS on CT related to NIPPV treatment,It is beneficial to assess the CT images in the NIPPV treatment of the related pneumonia in SARS.

Objective To explore the immunophenotype of children with acute myeloid leukemia(AML) and its clinical significance.Methods Statistics was used to analyze the relationship between the immunophenotype of AML and their French-American-Britain(FAB) classification,complete remission (CR) in one month and 3-years event-free survival(EFS).Results CR rate was 71.6% and 3-years EFS rate was 50.8%. HLA-DR and CD34 absent mainly in M3, associated with higher CR and EFS rate. So did CD33 negative cases, especially in M2. CD13 positive was significantly predictive factor for achieving CR.Co-expression of lymphoid antigens and NK cell antigens(CD56) with M2 which correlated with lower CR and EFS rate.Conclusions The negative of HLA-DR, CD34, CD33,as well as CD13 positive, have relationship with good prognosis. Lymphoid antigens and CD56 are poor prognostic factors.

Objective To investigate the stability of immunophenotyping in the course of relapse or at treatment failure of patients with acute lymphoblastic leukemia(ALL) and that of immunophenotyping of positive minimal residual disease(MRD).Methods From Aug.2000 to Dec.2007,33 children with ALL who relapsed or treated failure were enrolled. These children were detected MRD by flow cytometry. The immunophenotyping of children who relapsed or treated failure were compared with that of initial therapy;the immunophenotyping of MRD relapsed was compared with that of initial therapy.Results 1.In 23 out of 27 cases (85.18%) with B-ALL,changed at least 1 antigen between diagnosis and relapse.Six children with CD45 down-modulation and 2 children with CD45 up-modulation.Two children with CD19 down-modulation and 1 child with CD19 up-modulation.Six children with CD34 down-modulation and 4 children with CD34 up-modulation. Five children with CD10 down-modulation and 7 children with CD10 up-modulation.2.Six children with T-ALL had the same expression in CD45 between relapse and treatment failure. 3.These were 15 children had the least 1 case MRD,25 cases MRD were detected,these was 1 case up-modulation in CD45,1 case down-modulation in CD19,2 cases up-modulation and 8 cases down-modulation in CD34,3 cases up-modulation and 6 cases down-modulation in CD10.Conclusions Immunophenotyping of children with ALL may change at relapse and treatment failure. The frequency of change in B-ALL is higher than that of in T-ALL,but the change can not impact the detection of MRD.
