Blood types are very important because they are associated with blood transfusion, the diagnosis of hematological diseases and the related diseases. Rh system is a major blood group system as ABO system. Major Rh antigen is Rh (D) antigen. Minor Rh antigens are Rh (C), (c), (E), (e) antigen. Most of people have Rh (C), (c), (E), (e) antigen but some people don't have these antigens. The hematologists call this blood type -D-/-D- blood phenotype. -D-/-D- phenotype is blood group that have (D) antigen without (C), (c), (E), (e) Antigen. This blood type is rare throughout the world. Especially, fetal hydops associated with anti-C,-c,-E,-e antibody is very rare. We experienced a case of fetal hydrops associated with anti-C,-c,-E,-e antibodies and report it with a brief of literatures.

OBJECTIVECompare the characteristics of magnetic resonance imaging（MRI）liver T2*, cardiac T2* and serum ferritin on the assessment of iron overload.

METHODSA total of sixty-nine patients from November 2011 to June 2014 were enrolled in this study. Their cardiac and liver iron concentration levels were measured through MRI examination, with other clinical data were collected to perform statistical analysis.

RESULTSThe correlation between liver T2* and adjusted serum ferritin（ASF） was statistically significant（P=0.003）. However, no significant correlation was found between cardiac T2* and liver T2*, ASF, respectively. According to the statistical analysis of the 69 cases, it is found that the number of iron overload cases diagnosed by liver T2* was 62 and 20 cases were severe iron overload （32.26%）; the number of iron overload cases diagnosed by ASF was 47 and 14 cases were severe iron overload（29.79%）, while the number of iron overload cases diagnosed by cardiac T2* was only 25 and no severe iron overload cases.

CONCLUSIONSince SF was affected by other factors, it cannot reflect the level of iron overload in human body objectively. Now, liver T2* has become the gold standard for assessment of iron overload because of its good reliability and repeatability. However, cardiac T2* cannot correctly be used as assessment for iron overload, and it is only a method of evaluating the level of cardiac iron deposition.

'Num-chin syndrome', isolated mental neuropathy, is a rare manifestaion of malignant hernatologic diseases, but important sign for early diagnosis and prediction of clinical course and prognosis. Here we report 7 cases of numb-chin syndrome; one in leukemic transformation of malignant lymphoma, one in blastic crisis of chronic myelogenous leukemia and 5 in acute leukemia Two cases of acute leukemia revealed the 'numb-chin sign' in early course of disease before the diagnosis of leukemia and other three in aggravating state of acute leukemia. The therapeutic response and prognosis was poor and 5 cases expired in a few months.

OBJECTIVETo introduce practical diagnostic criterion of blood stasis syndrome (BSS), and to evaluate its reliability and validity.

METHODSBy referring to three diagnostic criteria of BSS [practical diagnostic criterion of BSS (criterion A), diagnostic criterion of BSS in 1986 (criterion B), Consensus of Integrative Medicine on BSS Diagnosis in 2011 (criterion C)], 712 patients from different departments of Xiyuan Hospital were recruited. The reliability of criterion A and its consistency with the other two criteria were assessed using Kappa coefficient. A Bayesian approach was also employed to assess the sensitivity and specificity of criterion A.

RESULTSAccording to the consistency check, criterion A presented good consistency when used by different researchers (the diagnostic accordance rate was 91. 96%, Kappa =0. 82, P <0.001). Meanwhile, there was an acceptable diagnostic consistency among the three diagnostic criteria. Bayesian estimation suggested that criterion A had higher sensitivity but similar specificity, as compared with criterion B or criterion C. Compared with criterion B [the median of sensitivity and specificity were 0. 762 (95% Cl: 0. 731 -0. 790) and 0. 902 (95% Cl: 0. 858 -0. 936) respectively, the median of sensitivity and specificity of criterion A were 0. 911 (95% CI: 0. 888 - 0. 930) and 0. 875 (95% CI: 0. 826 - 0. 915) respectively. Estimating the difference between criterion A and B, the median of sensitivity and specificity were 0. 149 (95% CI: 0. 112 -0.184) and -0. 026 (95% CI:-0. 085 -0. 033) respectively. Compared with criterion C [the median of sensitivity and specificity were 0. 831 (95% Cl: 0. 804 -0. 857) and 0. 892 (95% CI: 0. 848 - 0. 926) respectively], the median of sensitivity and specificity of criterion A were 0. 912 (95% CI: 0. 889 -0. 932) and 0. 880 (95%CI: 0. 833 - 0.919) respectively. Estimating the difference between criterion A and C, the median of sensitivity and specificity were 0. 081 (95% CI: 0.047 - 0.114) and -0.011 (95%CI: -0.070 -0.046) respectively.

CONCLUSIONCompared with criterion B and C, criterion A not only had better reliability, but also could significantly improve the sensitivity without obviously lowering the specificity.

OBJECTIVETo determine the pulmonary pathological changes in hematological malignancy patients with pulmonary complications.

METHODS17 hematological malignancy patients underwent surgical treatment were evaluated retrospectively. The pathological changes of all the surgical specimens were examined postoperatively by standard hematoxylin and eosin (HE) staining.

RESULTSPathological examination confirmed: aspergillus infection in 9 patients, sub-acute inflammation (fibrosis and hematoma formation) in 3, and each in 1 of pulmonary infarction with granulomatous tissue in the periphery; granulomatous inflammation with calcified tubercle; alveolar dilation and hemorrhage, interstitial fibrosis and focal vasculitis; intercostal neurilemmoma; and moderate-differentiated adenocarcinoma accompanied by intrapulmonary metastasis. And several operative complications (1 case of fungal implantation, 3 pleural effusion and adhesions and 2 pulmonary hematoma) were occurred. The coincidence rate of pre- and post-operative diagnosis was 9/14 (64.3%). After surgery, 8 patients were received hematopoietic stem cell transplantation (HSCT, allo-gene or autologous), with 7 succeeded. On effective secondary antifungal prophylaxis, 4 of 5 patients of aspergillosis succeeded in transplantation with free from mycotic relapse, one patient died from fungal relapse.

CONCLUSIONHematological malignancies with persistent and/or resistant pulmonary infection, hemoptysis, or unexplained lung diseases, should be treated in time by surgery operation to effectively eliminate residual disease and obtain a definitive diagnosis, so as to create a prerequisite condition for the following treatments. Moreover, the secondary antifungal prophylaxis can provide active roles for patients scheduled for chemotherapy and/or HSCT.

Individuals with Down syndrome have a high incidence of hematologic diseases such as transient myeloproliferative disorder (TMD) and acute leukemia comparing to the normal children. TMD usually undergoes complete recovery within a few months without any treatment. In Korea, there were several cases of TMD with Down syndrome in the literatures, but no reports of TMD in a phenotypically normal newborn with mosaic Down syndrome. We experienced a case of TMD in a 19- day-old male who was phenotypically normal newborn with mosaic Down syndrome. Specific treatment was withheld, hematologic recovery occurred within one month of diagnosis. We report the case with brief review of literature.

BACKGROUND: Bcr-abl rearrangement is the molecular hallmark of chronic myelogenous leukemia (CML). The test for bcr-abl rearrangement, especially using RT-PCR, is the standard test for the diagnosis of CML. We analyzed hematological significances of bcr-abl rearrangement by RT-PCR and the breakpoint distribution within the major bcr in CML patients. METHODS: From 1994 October to 1997 September, we performed the bcr-abl rearrangement using RT-PCR, in 268 untreated patients with various hematologic diseases, and classified the breakpoints within BCR gene as three types (b2a2, b3a2, e1a2) according to PCR product sizes. We compared hematologic parameters between two groups of b2a2 and b3a2 breakpoints in CML. RESULTS: Among the patients with clinically diagnosed CML, 96.8% (61/63) were bcr-abl positive. In ALL, 52.8% (19/36) were bcr- abl positive. All patients with hematologic diseases other than CML or ALL were bcr- abl negative. Among 61 CML patients with positive bcr-abl rearrangement, 19 patients (31.1%) showed b2a2 type and 42 patients (68.9%) b3a2 type. Patients with b3a2 breakpoints showed more frequent peripheral basophilia (P<0.01) than those with b2a2 type. However, other hematologic parameters were not statistically significant. CONCLUSION: RT-PCR test for bcr-abl rearrangement is a specific and efficient test for the diagnosis of CML. However, the hematological significance of b2a2 and b3a2 types is uncertain in CML.
