ObjectiveTo analyze hospitalized death related factors in elderly patients with nonST-segment elevation myocardial infarction (NSTEMI). MethodsThree hundred and two patients (≥65 years old) with NSTEMI were included. Thirty-two patients of them died in hospital (death group). Their clinical data were retrospectively analyzed and correlated factors for in-hospital death were evaluated. ResultsCompared with survival group, patients in death group were more likely to have 3 or more chronic diseases,heart function killip grades Ⅲ- Ⅳ, heart rate＞ 100/min and peripheral blood WBC count＞10X 10＜'9＞/L on admission (all P＜:0.05). There was no significant difference in fasting plasma glucose level and serum creatinine on admission between the two groups (both P:＞0.05). But after glomerular filtration rate(eGFR) were estimated by the modified abbreviated MDRD equations based on the Chinese CKD patients, patients in death group were more likely to be with renal dysfunction and pulmonary infection (both P＜0.01 ). Multiple logistic regression analysis showed that heart function killip grades Ⅲ-Ⅳ, renal dysfunction evaluated by eGFR, pulmonary infection on admission were the independent predictors for in-hospital death in elderly patients with NSTEMI. ConclusionsCoexistence of 3 or more chronic diseases is a related factor of death and heart function killip grades Ⅲ-Ⅳ, renal dysfunction evaluated by eGFR and pulmonary infection are the independent predictors for in-hospital death in elderly patients with NSTEMI.

The Formosan sika deer (Cervus nippon taiouanus) is an endemic subspecies in Taiwan. The original wild deer has been extinct since the late 1960s. The largest captive population is located at the Taipei Zoo. Except for infectious disease outbreaks, no systemic medical research has been reported for this subspecies. This study was conducted to analyze the medical status of the captive Formosan sika deer population, including the hematological and serum chemistry characteristics. To accomplish this, medical records for 34 Formosan sika deer from January 2003 to January 2014 were acquired and analyzed. The most common illness and cause of death was trauma, followed by gastrointestinal and respiratory disease, respectively. The hematologic and serum chemical values of healthy adults were quite different from those of sika deer (Cervus nippon yesoensis). This study provides a closer medical understanding of this subspecies and the results will facilitate its management.

OBJECTIVETo analyze the characteristics of acquired pure red cell aplasia (PRCA) secondary to T cell large granular lymphocyte leukemia (T-LGLL).

METHODSFourteen patients with T-LGLL associated with PRCA between 2000 and 2006 in our hospital were retrospectively analyzed.

RESULTSThe median age at diagnosis was 61 years with equal gender distribution. The PRCA had indolent process, mainly presenting with anemia. Of the 14 patients, 9 had mild to moderate splenomegaly, one hepatomegaly and one lymphadenopathy. The median Hb level was 61.5 g/L and the median WBC count 4.3 x 10(9)/L. The median percentage and count of LGL in peripheral blood were 0.36 and 1.9 x 10(9)/L respectively. The median percentage of LGL in BM was 0.165 (0.085 - 0.410). Some patients had serologic abnormalities. All the 12 cases with available bone marrow cell cytogenetics showed normal karyotypes. With cyclosporine A or glucocorticoid immunosuppressive therapy, the overall response was 91%.

CONCLUSIONT-LGLL was one of the major causes of acquired PRCA. This type of PRCA has the similar clinical and laboratory feature to that of other type of PRCA and has a good response to immunosuppressive therapy.

OBJECTIVETo study the bone marrow microvessel density (MVD) and vascular endothelial growth factor (VEGF) expression and their clinical significance in patients with aplastic anemia (AA).

METHODSBone marrow biopsies in 51 newly diagnosed patients with AA were evaluated the MVD and VEGF expression by immunostaining with anti-factor VIII related antigen and VEGF monoclonal antibodies at regular time points after immunosuppressive therapy (IT).

RESULTSThe mean bone marrow MVD in AA group was 5.5 +/- 3.5, being significantly lower than that in normal control group (8.7 +/- 3.4, P < 0.05). MVDs of SAA and NSAA patients were 7.4 +/- 2.9 and 4.3 +/- 3.4, respectively, being significantly different (P < 0.01). The VEGF expression in AA group was significantly lower than that in control group [(6.7 +/- 8.4)% vs (14.7 +/- 6.1)%, P < 0.01], but there was no difference between SAA and NSAA. Bone marrow MVD and VEGF were significantly increased after IT in 22 responded AA patients.

CONCLUSIONBone marrow MVD and VEGF expression are low in AA patients which may be one of pathophysiologic mechanisms of bone marrow failure in AA. Proangiogenic and ameliorating microcirculation agents together with IT might accelerate the recovery of hematopoiesis in AA patients.

OBJECTIVETo analyze the clinical and laboratory features of patients with congenital dyserythropoietic anemia type I (CDA-I), and improve the clinical diagnostic accuracy.

METHODSThe clinical and hematological features of 5 patients diagnosed as CDA-I in our hospital between July 2002 and July 2007 were analyzed retrospectively, and the related literatures was reviewed.

RESULTSFive CDA-I patients, 1 male and 4 females, all had a long history of varied degree of chronic anemia. One patient had congenital malformations, 3 jaundice and 4 hepatosplenomegaly. Bone marrow specimens invariably showed hypercellularity due to erythroid hyperplasia with megaloblastic changes, irregularly shaped nuclear, and chromatin bridges in 0.2% to 0.6% of all erythroblasts. All the 5 patients' bone marrow erythroblasts showed spongy heterochromatin appearances (swiss-cheese) with electron microscopy examination. There was no morphologic abnormality in the granulocytes and megakaryocytes. Serum ferritin levels were increased in 3/4 patients. One patient had been misdiagnosed as hereditary spherocytosis and performed splenectomy in the local hospital with no improvement in Hb level.

CONCLUSIONSCDA-I is a rare congenital anemia characterized by ineffective erythropoiesis, jaundice, hepatosplenomegaly and iron overload, and may be misdiagnosed. Keeping these manifestations in mind should avoid misdiagnosis.

OBJECTIVETo analyze the characteristics of T-cell large granular lymphocyte leukemia (T-LGLL).

METHODSRetrospectively analyze the clinical and laboratory data of 27 patients with T-LGLL diagnosed between 1999 and 2007 in our hospital.

RESULTSThe median age at diagnosis was 48 years. All patients were symptomatic, mainly complaining of fatigue. Of the 27 patients, 14 (51.9%) had splenomegaly, and 4(14.8%) hepatomegaly. Rheumatoid arthritis was not present in any patients. The most frequent hematological abnormality was anemia (24 patients, 88.9%) with a median Hb level of 57.5 g/L. Pure red cell aplasia was found in 18 patients (66.67%). The median WBC count was 4.24 x 10(9)/L and 19 cases were neutropenia (ANC < 1.5 x 10(9)/L). The median LGL count in peripheral blood was 1.45 x 10(9)/L and most of them (77.8%) were less than 2.0 x 10(9)/L. Twenty-two patients (81.5%) showed the CD3+ CD8+ CD57+ CD56(-) LGL phenotype. With immunosuppressive therapy, 91.3% of patients responded and complete hematological remission rate was 65.2%.

CONCLUSIONT-LGLL mainly presented with anemia and complete hematological remission rate was 65.2%. Pure red cell aplasia was commonly associated with the disease. The patients had a good response to immunosuppressive therapy.

OBJECTIVETo investigate the clinical significance of 24-hour blood pressure monitoring (ABPM) for evaluating the treatment outcome of nerve-mediated syncope (NMS) in children.

METHODSTwenty-eight children with NMS confirmed by a head-up tilt table test (HUTT) (12 males and 16 females, aged 6-13 years) and with a chief complaint of unexplained syncope or pre-syncope between February 2010 and August 2012, were included in the study. These children received health education combined with therapy using oral rehydration salts solution and were then reexamined for clinical symptoms as well as HUTT and ABPM results.

RESULTSOf 28 NMS cases, 22 were vasodepressive type, 5 were mixed type, and 1 was cardioinhibitory type. The follow-up showed that 27 (96%) of all cases had improved clinical symptoms, and 18 (64%) had improved HUTT results. The ABPM follow-up revealed no significant changes in 24-hour mean systolic pressure, 24-hour mean diastolic pressure, daytime mean systolic pressure, daytime mean diastolic pressure, nighttime mean systolic pressure, nighttime mean diastolic pressure, day-night difference of systolic pressure, and day-night difference of diastolic pressure after treatment (P>0.05). The percentage of children with a dipper blood pressure pattern increased from 29% (8/28) before treatment to 50% (14/28) after treatment; the percentage of children with a non-dipper blood pressure pattern decreased from 71% (20/28) before treatment to 50% (14/28) after treatment.

CONCLUSIONSAs an effective, objective and non-invasive monitoring means, ABPM is of some clinical significance for evaluating the treatment outcome of NMS in children.

OBJECTIVETo investigate the impact of immunosuppressive therapy (IST) on genetic instabilities of bone marrow hematopoietic cells (BMHCs) in patients with aplastic anemia (AA).

METHODSComet assay as used to detect genetic instabilities of hematopoietic cells from patients, and the percent of DNA in comet tail (TDNA), tail length (TL), tail moment (TM), olive tail moment (OTM) and the rate of comet cells were measured. BMHCs from AA patients were examined with comet assay before and after IST, and the results were compared with those from controls.

RESULTSComet parameters from 91 AA patients including TDNA, TL, TM, OTM comet cell percentage were (5.0 +/- 4.0)%, 11.3 +/- 7.2, 1.7 +/- 2.0, 1.5 +/- 1.4, (16.8 +/- 13.7)%, respectively, which were significantly higher than those from control group (P < 0.05). There were statistical differences between the comet parameters of severe AA (SAA)/non-SAA (NSAA) and those of control group (P < 0.05), but no difference in the comet parameters between SAA and NSAA patients (P > 0.05). The TDNA, TL, TM, OTM and comet cells percentage were (4.4 +/- 3.6)%, 10.4 +/- 7.5, 1.4 +/- 1.6, 1.3 +/- 1.4 and (20.2 +/- 21.2)%, respectively at 3 months after IST in 53 SAA patients and were (3.7 +/- 3.3)%, 10.0 +/- 7.2, 1.2 +/- 1.8, 1.1 +/- 1.3 and (18.5 +/- 19.0)% respectively at 6 months after IST in 30 SAA patients, being no statistical difference from those of 58 SAA patients before IST (P values were all > 0.05).

CONCLUSIONBMHCs of AA had inherent genetic instabilities which were not increased by recent IST. It indicated that there was no correlation between IST and the development of clonal hematologic disorders in AA.

OBJECTIVETo analyse the efficacy and side-effects of rabbit antithymocyte globulin (ATG) and cyclosporin A (CsA) as the first-line therapy for childhood severe aplastic anemia (SAA).

METHODSSeventy-one childhood SAA patients treated with rabbit ATG + CsA as first line therapy were retrospectively analysed.

RESULTSSeventy-one SAA patients, including 38 SAA and 33 very severe aplastic anemia (VSAA), were enrolled. The median age was 12 years. Of these patients, 3 died within 3 months after the immunosuppressive therapy (IST). The overall response rate was 67.6% (46/68) and the median time to transfusion independent was 53 days. Thirty-three patients (48.5%) obtained remission in 3 months after the IST and 45 (67.2%) in 6 months. The response rates were 57.7% (15/26), 56.5% (13/23) and 94.7% (18/19) for patients less than 10 years old, 10 - 15 year-old and 15 - 18 year-old, respectively. Sixty patients suffered from serum sickness on the IST. Three patients relapsed and another 3 unrespond patients received retreatment of IST, and one patient progressed to myelodysplastic syndromes (MDS).

CONCLUSIONRabbit ATG in combination with CsA as first line therapy for childhood SAA/VSAA can lead to overall response rate of 67.6% with minor adverse effects.
