Objective To Analyze the imaging characteristics of intraparenchymal schwannoma and the related pathology,in order to improve the accuracy of diagnosis and be in favor of the clinics and the prognosis.Methods Four cases were confirmed to be intraparenchymal schwannoma by pathological and immunohistochemistry examination.One case was examined with precontrast and enhanced CT scanning,one with unenhanced MRI scanning,two with unenhanced and enhanced CT and MRI scanning.Their images were retrospectively analyzed.Results Of the four cases,three patients were less than 30 years old,with tumors located supratentorially.Cysts were found in all cases,with nodules on the wall in 3 cases.The nodules were enhanced markedly in two cases and moderately in one ease.In addition,calcification was detected in one case and prominent peritumoral edema existed in 1 case.The picture of the pathology demonstrated Antoni type A and Antoni type B.Immunostaining showed intense immunoreactivity for S-100 protein and Vim and negative immunoreactivity for GFAP and EMA.Conclusions Intraparenchymal schwannoma mostly occurred in juvenile,which located supratentorially in most cases.The presence of a cyst and peritumoral edema together with the tumor appears to be characteristic of intraparenchymal schwannoma.Calcification or the enhanced nodule is the helpful sign for the diagnosis.Combining the imaging findings with the pathology and immunohistochemistry results can gain the accurate diagnosis.

Objective To know the mental status of spouses of infertility women and the influence of different conditions on spouse of infertility women, so as to pertinently do the health education well. Methods A questionnaire survey was conducted among spouses of 107 infertility women using the SAS (self-rating anxiety scale). Results The score of SAS of spouses of infertility women was (37.68 ± 7.70). The difference had statistical meaning compared to the normal model in China. There were statistical meanings in anxiety status of spouses of infertility women with different ages, educational degree and the ability of economic acceptance (P < 0.05). Conclusions The individual mental nursing should be given to the infertility women and their spouses according to the different situations of individuals, thereby reducing their anxiety emotion and making them actively cooperate with the therapy and nursing.

Ph chromosome occurs in nearly all patients with CML, and eliminating Ph-positive clone is a major target in the treatment of CML. IFN-alpha is a well-known effective treatment in chronic phase CML. The cytogenetic response and the prognostic factors in 128 CML patients treated with IFN-alpha were retrospectively studied. IFN-alpha administered singly at a dose of 3 million U/day for 2 - 3 times a week or in combination with either hydroxyurea (Hu), busulfan (Bu), low dose Ara-C or harringtonine. Karyotyping was examined by G-banding before and after IFN-alpha-based treatment. The results showed that all patients achieved complete hematological remission. Cytogenetic response occurred in 36 of 118 patients with standard t (9;22) translocation; 3 of these 36 patients had a complete cytogenetic response (Ph = 0), 13 had major cytogenetic responses (Ph < 35%) and 20 had minimal response (Ph > 35%). The total cytogenetic effectiveness was 13.6% (16/118). Four of seven patients with complicated variant translocation also achieved cytogenetic response, 2 of them had a major cytogenetic response and 2 had minimal response. Factors influenced the prognosis associated with cytogenetic response included sex, patient status at diagnosis and IFN-alpha administered singly or in combination with other chemotherapeutic agents. IFN-alpha could not prevent the progression of CML. It is concluded that Ph(+)CML patients with both standard and variant translocation had major cytogenetic response to IFN-alpha treatment at a dose of 6 - 9 million U/week in single or combination with Hu/Bu, however, IFN-alpha treatment could not prevent disease progression. Long term survival was also observed in patients with variant translocation treated with IFN-alpha. Regular cytogenesis examination in CML patients is necessary during IFN-alpha therapy, which is useful to reflect curative effect and progression of the disease.

The purpose of this study was to explore the significance of abnormal karyotype in diagnosis and prognosis estimation of myelodysplastic syndrome (MDS). Chromosome analysis were performed in 306 cases of MDS using the short-term culture of bone marrow cell and G-banding technique, and in partial cases FISH technique was used for this analysis. 93 out of 306 cases were followed up. The results showed that 144 cases (47.1%) had clonal chromosome aberrations. The most common chromosomal aberrations included +8, translocation, complex or high complex karyotype, -7/7q-, 20q-/-20, trisomy 1 or partial trisomy 1, +11/+11q-, -9/9q-, +9/9q+, -Y, dup(1q), +21. The rate of abnormal karyotype in refractory anemia with erythroblasts (RAEB) and refractory anemia with erythroblasts-transformation (RAEBT) were much higher than in refractory anemia (RA) and refractory anemia with sideroblasts (RAS) (P < 0.05). The rate of abnormal karyotype among those cases with mutagen contact history were higher than those in cases without mutagen contact history. The patients with abnormal karyotype had a mean survival time much shorter than patients with normal karyotype (P < 0.005) and had a higher risk transforming into acute leukemia (P < 0.05). The worst outcome was observed in those patients with a complex or high complex karyotype, -7/7q- and trisomy 11. In conclusion, MDS is highly heterogeneous disorders and karyotype analysis is helpful for its diagnosis, treatment selection and prognosis estimation.

To investigate the cytogenetic and clinical characteristics of inv(3q) (q21q26) and t(3;3) (q21; q26) aberrations as well as prognosis, cases were collected and chromosome specimens of bone marrow cells were prepared by 24-hour culture, while G-banding technique was used to perform karyotyping. The results showed that the simple inv(3q) and t(3; 3) aberrations were rare, they commonly combined with other chromosome aberrations such as -7/7q- and t (9; 22). The involved diseases included myelodysplastic syndromes, acute myeloid leukemia and chronic myelogenous leukemia in blast crisis. Out of 24 patients, 2 patients diagnosed with M(5) subtype did not achieve complete remission after multiple chemotherapy; 2 patients received allogenic stem cell transplantation relapsed. It is concluded that 3q21q26 aberration commonly combined with chromosome aberration 7/7q-, for these patients the efficacy of chemical therapy is poor, the efficacy of bone marrow transplant is too poor, these patients with inv(3q) and t(3; 3) aberrations have poor prognosis and short overall survival.

OBJECTIVETo study the morphologic and cytogenetic change in acute promyelocytic leukemia (APL) patients during the tetra-arsenic tetra-sulfide (TATS) treatment and the mechanism of TATS.

METHODSThe bone marrow cells of 13 newly diagnosed and 7 recurrent APL patients were studied through FISH and morphology during the TATS treatment by special and repeated marrow culture.

RESULTSCytomorphological study of 8 cases (6 untreated and 2 recurrent) showed that TATS could differentiate APL cells forward to mature granulocytes. There was obvious correlation between the reduced t (15; 17) positive cells and the reduced APL cells (r range 0.7298 - 0.9989). Except one patient with t (11; 17), 19 (13 untreated and 7 recurrent) with translocation t (15; 17) achieved clinical CR including 16 who achieved cytogenetic CR.

CONCLUSIONTATS has a differentiation-inducing effect on untreated and recurrent APL, with haematological CR and cytogenetic CR achieved. Measurement of t (15; 17) positive cells by FISH technique can reflect the change of APL cells objectively.

To explore the cytogenetics and related clinical characteristics of adult acute leukemia with Philadelphia chromosome positive (Ph(+)AL), MIC classification by morphology, immunology and cytogenetics was used to retrospectively study 79 patients with Ph(+)AL hospitalized in the Institute of Hematology, People Hospital in Beijing from October 1991 to September 2003. The results showed that 6.9% cases were diagnosed as Ph(+)AL and classified into three subtypes: acute lymphoblastic leukemia (Ph(+)ALL) in 56 patients (18%), acute myeloid leukemia (Ph(+)AML) in 10 patients (1.2%) and mixed acute leukemia (Ph(+)MAL) in 13 patients. B-cell antigen expression was found in 52 out of 56 patients with Ph(+)ALL. 54.4% (43/79) patients had additional chromosome abnormalities including chromosome 7, double Ph and plus 8, etc. Complete remission (CR) rate of Ph(+)ALL and Ph(+)MAL was 57.0%, none of Ph(+)AML achieved CR. Median overall survival of Ph(+)ALL, Ph(+)MAL and Ph(+)AML were 10, 10 and 2.5 months respectively. It is concluded that Ph(+)AL has highly heterogeneity involving various differentiated stages of immature leukemic cells. Since the poor prognosis associated with this kind of AL, early diagnosis with MIC classification is a prerequisite to take more effective conditioning regimen and prospectively consideration of allogeneic stem cell transplantation to improve prognosis.

OBJECTIVETo investigate the clinical value of glycosylated G-CSF combined with middle-high dose cyclophosphamide (Cy) or conventional chemotherapy with increased dose of Cy for mobilizing peripheral blood progenitor cells in patients with tumor.

METHODSThirty patients from four hospitals in Beijing region were enrolled in this clinical study. Diagnoses of the patients were non-Hodgkin' lymphoma (n = 21), Hodgkin disease (n = 1), breast cancer (n = 7) and ovary cancer (n = 1). Autologous peripheral blood progenitor cells (APBPC) were mobilized by middle-high dose Cy or conventional chemotherapy with increased dose of Cy combined with G-CSF. G-CSF was given subcutaneously from the nadir of the white blood cell (WBC) count to the end of PBPC collection. The dosage of G-CSF was 250 microg/d in 29 patients and 500 microg/d in 1 patient. When WBC count was > 5 x 10(9)/L, APBPC were harvested with CS 3000 plus/COBE Spectra.

RESULTSThe average dosage of Cy was 3.95 g (2.3 g/m(2)). The doses of G-CSF were 3.1 approximately 6.4 microg x kg(-1) x d(-1). Thirteen patients (43%) were collected twice, 14 patients (47%) three times and 3 patients (10%) four times. All of the patients could tolerate the treatment regimens. Seven patients had bone pain after G-CSF injection and one was severe, one patient had headache and one had nausea and vomiting.

CONCLUSION250 microg glycosylated G-CSF combined with middle-high Cy or conventional chemotherapy with increased dose of Cy combined G-CSF is an optimal method for APBPC mobilization in tumor patients.

OBJECTIVETo explore the relationship between evolution of karyotype and clinical progress in myelodysplastic syndromes (MDS) and estimate the clinical outcomes of high risk patients received allogeneic hematopoietic stem cell transplantation (allo-HSCT).

METHODSContinuous karyotyping were performed using short-term culture of bone marrow cells and G-banding technique to follow up 41 cases of MDS patients.

RESULTSKaryotype analysis showed that 24 cases (58.5%) had clonal karyotypic abnormalities. In a median follow up of 34 months (7 approximately 72 months), 6 cases had karyotype evolution in 12 cases with clinical deterioration, while only one had karyotype evolution in 18 cases without clinical progression. The involved chromosomes included No. 2, 4, 7, 8, 10, 11, 17 and 21. Six out of 7 patients who received allo-HSCT attained complete remission and their abnormal karyotypes returned to normal. Four patients with clinical remission after therapy attained cytogenetic remission too.

CONCLUSIONKaryotype evolution showed a strong relationship with clinical progress in MDS patients, and indicated a very poor prognosis. Patients with clinical progress had much higher incidence of clonal evolution than those with relatively stable clinical course. Allo-HSCT should be considered the first choice of therapy for MDS patients with clonal karyotypic abnormalities.

The aim of study was to investigate the importance of chromosome aberration in differential diagnosis of eosinophilia and the chromosomal aberrations involved in patients with clonal eosinophilia. 65 cases of eosinophilia were collected and chromosome specimens of bone marrow cells were prepared by 24-hour culture, and G-banding technique was used for karyotyping. The results showed that out of 65 cases, chromosome 16 inversion was detected in 9 patients suspected as M(4Eo), and among the other 56 cases, 5 were detected with chromosomal aberrations (8.9%). Combining clinical, hematological and cytogenetical data, the 5 patients were diagnosed as acute myeloid leukemia with eosinophilia, chronic eosinophilic leukemia, 8p11 myeloproliferative syndrome, chronic myeloid leukemia in acute phase and acute myeloid leukemia-M(4Eo) respectively. The detected chromosomal aberrations were +14, t (5; 12) (q31; p13), t (8; 9) (p11; q32), t (9; 22) (q34; q11) and inv (16) (p13 q22). In conclusion, cytogenetical detection is very important in differential diagnosis of clonal eosinophilic disorders and chronic eosinophilic leukemia, which is suggested to be done routinely in clinic.
