A 48-year-old man was referred to our hospital in December, 2005 because of general fatigue, gait disturbance and bradycardia. He had a history of polysurgery due to recurrent ileus and had been treated with home total parenteral nutrition for the short-bowel syndrome since 2003. Clinical findings on admission included marked emaciation and severe weakness of the extremities. Pancytopenia was noted in the peripheral blood. The serum levels of copper and ceruloplasmin were 3 microg/dl and 3 mg/dl, respectively, while Vit. B12 and folate were within the normal range. The bone marrow demonstrated cytoplasmic vacuolation in the myeloid and megakaryocytic series, and sideroblastic changes. No evidence of hematologic malignancies was presented. The diagnosis was copper deficiency and the patient was treated with copper supplementation. Four weeks after copper therapy, the serum level of copper rose to 50 microg/dl and ceruloplasmin to 14 mg/dl. Significant improvements in the hematologic profile, ECG findings and weakness of extremities were noted. Although bicytopenia (anemia and neutropenia) is considered to be a feature of hematologic disorders caused by copper deficiency, the present case showed pancytopenia. The exact mechanism of the unusual association of thrombocytopenia and other abnormalities with copper deficiency remains to be elucidated.

Deficiency of both Qi and Yin Syndrome (DQYS) is one of the common syndromes in traditional Chinese medicine (TCM), mainly characterized by tiredness, emaciation, anorexia, fidget, palpitation and rapid pulse, and so forth. Currently, there is no available animal model which can reflect the clinical features of this syndrome. In the present paper, we observed the time-course changes of whole behavior, body weight, food intake, locomotive activity and electrocardiogram in mice exposed to chronic intermittent hypoxia for 6 weeks, and measured bleeding time at last according to the clinical features of DQYS and one key pathological factor. The results showed that the mice exposed to intermittent hypoxia for certain time presented lackluster hair, dull looking hair, resistance, attacking, body weight loss, food intake decline, locomotive activity decrease, heart rate quickening and T wave elevating, which were similar to the major clinical features of DQYS. Meanwhile, bleeding time shortening was also found, which was consistent with the clinical fact that DQYS often accompanied with blood stasis. The possible explanation was also outlined according to the available literature. Such findings suggested chronic intermittent hypoxia could induce similar symptoms and signs in mice accorded with the clinical features of DQYS, which provided a suitable animal model for evaluation of drugs for the treatment of this syndrome and further exploration of pathological process or correlation of the syndrome and related diseases.

Philadelphia chromosome-positive acute myeloid leukemia is controversial and difficult to distinguish from the blast phase of chronic myeloid leukemia. As a myeloid neoplasm, rare cases of this leukemia manifest multiple soft-tissue tumors or bone lytic lesions. In this paper, we describe a 49-year-old male patient who had an abrupt onset with sharp chest pain, fever, fatigue, emaciation, and splenomegaly. 18F-fluoro-deoxy-glucose positron emission tomography/computed tomography (18F-FDG PET/CT) result showed diffuse and uneven hypermetabolic lesions in the bone marrow with peripheral bone marrow expansion, multiple soft tissue neoplasms with high 18F-FDG uptake, and lytic bone lesions. Bone marrow smear and biopsy detected aberrant blast cells expressing myeloid rather than lymphoid immunophenotype marker. For the existence of Philadelphia chromosome and BCR-ABL1 fusion gene together with complex chromosome abnormalities, a diagnosis of Philadelphia-positive acute myeloid leukemia was made, although the type (de novo or blast crisis) remained unclear.
