Objective To evaluate the efficacy and toxicity of paraplatin used within the cavity for the treatment of malignant serous cavity effusion. Methods Puncturing with catheter of centre vein and permanent catheter, withdrawing proper volume of malignant effusion, 150 ～ 450 mg paraplatin was infused into the serous cavity each time for once or twice a week till the effusion was disappeared or there was no change. Results 76 cases were evaluable for response and toxicity. There were 21 patients with CR, 33 patients with PR and 22 patients with NR. The ORR was 71 %. Among them, the RR in malignant pleural effusion group was 79 %(27/34), 50 %(13/26) in the peritoneal effusion and 87 %(14/16) in the pericardial effusion. Only I ~ II degree bone marrow suppression was observed. Conclusions Paraplatin used within the cavity is more effective and safe for treating malignant serous cavity effusion.

Phthalic acid esters (PAEs) are commonly used plasticizers and solvents. Human body is exposed and absorbed mainly through diet, skin and air inhalation. The biological samples such as urine, blood, saliva, semen and breast milk generally contain PAEs and their metabolites, but the concentrations of PAEs metabolites vary in different samples. In the general population, the levels of PAEs are higher in children than in adults, and higher in women than in men; the levels of PAEs are higher in the occupational population than in the general population. In this paper, the research of PAEs related human biomonitoring in the general population and occupational population at home and abroad is reviewed, so as to provide the basis for reducing the exposure of PAEs and related health risk.

【Objective】 To solve the difficulty of RhD blood group typing in a patient with double population(DP) of red blood cells for RhD antigen by serological and genotyping analysis. 【Methods】 Separation of the two populations of red blood cells of the patient was performed using capillary centrifugation method. ABO, RhD and RhCE typing, direct anti-human globulin test (DAT), irregular antibody screening, antibody identification and blood crossmatching of the patient were conducted using the standard serological methods. The hybrid Rhesus zygosity analysis of the RHD gene was performed by PCR-RFLP method. RHD and RHCE genotype of the patients were identified by PCR-SSP method. 【Results】 The patient was B type but with DP of red blood cells for RhD, Rhc and RhE antigens. DAT of the patient was positive and the alloanti-D was detected in serum. The RHD zygosity was D-/D- homozygote. PCR-SSP testing showed the RHD gene deletion (RHD * 01N. 01/01N.01 genotype) and Ccee of RHCE genotype in the patient, which was consistent with RHD zygosity analysis. 【Conclusion】 This is a special case with D-negative phenotype which was wrongly detected as D-positive type after D-positive red blood cells transfusion in emergency. When the DP of red cells for D antigen encountered like this case, the RhD typing can be accurately determined by using RHD genotyping analysis to provide strong evidence to the clinical blood transfusion.

【Objective】 To identify the specificity of alloantibody against high-frequency antigens in one case suffering with severe hemolytic diseases of the fetus and newborn (HDFN) and to screen for matching blood for transfusion. 【Methods】 The HDFN test and the antibody serological identification tests in the mother were performed. Several common high frequency antigens of maternal red blood cells (RBCs) were determined. IgG subtype coated on the RBCs of the newborn was determined. The phagocytic efficiency of the antibody was tested using the monocyte phagocytosis of sensitized erythrocyte by flow cytometry in vitro. Sanger sequencing of DI gene was performed in the mother, father and mother’s brother. The diluted maternal plasma was used for large scale screening of matching blood using IAT in Coomb’s gel card. 【Results】 Di(b-) phenotype was identified in the mother of the newborn and anti-Di^b (titer: 512) related HDN was detected in the newborn. IgG1 and IgG2 subtypes of anti-Di^b were detected and the rate of monocyte phagocytosis was 88.83%(74.7/84.09). The compatible blood was not detected in the maternal relatives. Subsequently, the newborn received the matching RBCs of two Di(b-) donors identified from 5 520 blood donors and discharged from the hospital. We screened out 17 Di(b-) donors out of 51 334 blood donors, indicating that the distribution frequency of Di(b-) among blood donors in Guangzhou was about 0.033% (17/51 334). 【Conclusion】 By serology and molecular biology methods, the newborn was identified with HDFN caused by anti-Di^b, and an effective large-scale screening method for Di (b -) rare blood types was established to find matching blood, which supported the establishment of rare Di(b-) blood database.

【Objective】 To elucidate the prediction ability of monocyte monolayer assay(MMA) used in hemolytic disease of fetus and newborn(HDFN) caused by IgG anti-M. 【Methods】 Plasma from eight pregnant women containing IgG anti-M were collected, and were divided into two groups(4 cases with HDFN, with severe clinical symptoms such as fetal hydrops, and 4 cases without HDFN) according to the clinical outcomes. M antigen positive cells were sensitized with dithiothreitol(DTT) treated plasma from eight pregnant women respectively. MMA was performed by coincubation with monocytes and sensitized M cells, along with negative and positive control set up. T-test was conducted to compare the difference in phagocytic efficiency between two groups. 【Results】 The phagocytic efficiency in group with HDFN were 15.37%, 13.05%, 9.17% and 24.50% respectively, with the mean value of 15.52%, while the group without HDFN were 8.74%, 11.07%, 5.12% and 6.23% respectively, with the mean value of 7.79%.There was no significant difference in phagocytic efficiency between two groups(P>0.05). The mean values of both groups were not significantly different from the negative control(P>0.05), but both were significantly lower than positive control(P<0.05). 【Conclusion】 The low phagocytic efficiency couldn’t convince that the MMA is an effective predictor for the HDFN caused by IgG anti-M, indicating that another mechanism might be responsible for it rather than monocyte phagocytosis. The assessment of the peak systolic velocity in middle cerebral artery of the fetal should be considered in the management for pregnant women who produce IgG anti-M to estimate the situation of fetal anemia.
