The herbs used as the material for traditional Chinese medicine are mostly planted at mountain areas where there is appropriate weather condition. Due to the complex terrain condition in mountain area, the planting at such places is always associated with a scattered pattern, which inevitably bring difficulty to the work of accurate measurement for the planting area. Advanced research about monitoring the planting area for medicine-herb under complex environmental condition is so critical and meaningful for developing the medicine-herb planting to a large scale and an industry. Therefore, this research, taking the planting of Herpetospermum pedunculosum in Luding county as an example, utilizes RS&GIS: using the image data from TM and ETM datum as the remote sensing information source, integrating GPS data from quadrat survey on the spots, and analyzing on a GIS platform, to extract the planting area of H. pedunculosum in Luding county. The results indicate that: (1) the method and technology used to estimate the planting area of H. pedunculosum are feasible and can be applied to monitoring the planting area of medicine-herb at mountain area under complex environmental conditions: (2) the planting area of H. pedunculosum in Luding county is estimated to be 857. 246 acres by the methods utilized in this research, which is closed to the value from local statistical data with an error range less than 5%; (3) in consideration of those inevitable errorrs generating from the procedures such as remote sensing data acquisition, data preprocessing, data interpretation, and so on, and the fact that the classification of remote sensing data, which must be implemented by those above procedures, was used directly to extract the herb type, the accuracy of area estimation for the herb is significantly influenced by the accuracy of classification for herb type, and the estimated area is inevitably associated with some error.

OBJECTIVETo investigate the significance of clinicopathological stage of chronic idiopathic myelofibrosis (CIMF) in WHO classification of 2001.
METHODSHistopathological analysis of bone marrow biopsy plastic-embedded sections stained with H-G-E and Gomori's stains and clinical features of 113 cases previously diagnosed as primary myelofibrosis (PMF) and 48 cases MPD-U (total of 161 cases which including male 79 and female 82) were studied retrospectively.
RESULTSThere was no significant differences on the clinical features among the cellular phase, collagen fiber phase, sclerotic phase and osteomyelosclerosis of 113 previously diagnosed patients. According to WHO classification 2001 of CIMF, previously diagnosis in 48 cases with MPD-U was WHO pre-CIMF, and in 113 cases with PMF was WHO CIMF-Fs. There were significant differences between of WHO pre-CIMF and WHO CIMF-Fs about clinicopathological features except age. The percentage of immature granulocytes, normoblasts, lymphocytes in peripheral blood, the size of hepatosplenomegaly, and the percent age of tear drop-like red blood cells in pre-CIMF were significantly lower than those in CIMF-Fs (P < 0.05). However, the number of hemoglobin and platelets in patients with pre-CIMF were significantly higher than that with CIMF-Fs (P < 0.01).
CONCLUSIONpre-CIMF and CIMF-Fs in clinical and histopathological features were different development stage of CIMF, while osteomyelosclerosis is a variant of CIMF, but not an independent disease.

OBJECTIVETo investigate the clinicopathologic features, diagnosis, differential diagnosis and the prognosis of hairy cell leukemia (HCL).
METHODSFifteen splenectomy specimens of HCL patients were investigated retrospectively using HE and immunohistochemistry in correlation with the follow-up information.
RESULTS(1) The male to female ratio was 2.75:1, age ranged from 36 to 68 years with a median of 47 years. The most consistent clinical feature at presentation was marked splenomegaly (100%). Other symptoms included anemia (80.0%), thrombocytopenia (60.0%), leucocytosis (53.3%), pancytopenia (20.0%) and the absence of B-symptom. (2) The proportion of hairy cells was (14.6 +/- 7.2)% in periphery blood and (47.3 +/- 23.8)% in bone marrow. The positive rate of TRAP assay was 62.5% in bone marrow; 85.7% for TPA test and the detection rate for RLC was 25% by transmission electric microscopy. The frequency of bone marrow involvement was 100%. (3) The average weight of 15 spleens was (3012 +/- 1974) g. The size of 6 spleens ranged from 16 cm x 10 cm x 5 cm to 32 cm x 20 cm x 14 cm. The white pulp of spleen showed a characteristic atrophy feature or even absent due to leukemic infiltration, predominantly involving the red pulp with some sinusoidal pattern. "Blood pool" change was an infrequent feature (3/15 cases). The nuclei of leukemic cells were round (13 cases) or bean-shaped (2 cases), nucleoli inconspicuous or disappeared. The abundant cytoplasm and prominent cell border resulted in a "fried egg" appearance. By immunohistochemistry, leukemic cells were positive for CD45RA, CD20, PAX-5, CD25, CD11c, Annexin A1 and cyclinD1, but negative for CD3 and CD43. (4) 13 cases (86.7%) have been followed-up and all are alive. Among them, 9 cases are living well more than 5 years and 7 more than 10 years.
CONCLUSIONSSplenomegaly is frequently the first manifestation of patients with HCL and occurred predominantly in the middle to elderly adults. Definite diagnosis of HCL requires a combined histological and immunohistochemical assessment of the splenectomy specimen, bone marrow biopsy and aspirate.

Cycloheximide (CHX) inhibits protein synthesis in most eukaryotic cells and it is a well-known tool commonly used in biochemical research. In this paper, the antiviral spectrum of CHX against several DNA and RNA viruses have been evaluated. CHX showed strong inhibitory activities against several RNA viruses such as HIV-1, influenza viruses, coxsackie B virus, enterovirus (EV71) and several DNA viruses such as HSV and HCMV. Especially the strong inhibitory activities of CHX against coxsackie B virus and enterovirus caught our attention, since effective drugs available in clinic are limited. The SAR of CHX derivatives also has been discussed in the paper. The hydroxyl group at C-2' and carbonyl group at C-2" of CHX are essential for its antiviral activity. And modification to these groups results its derivatives' antiviral activities reduced or lost.

OBJECTIVETo explore the hematopathologic features of T-cell large granular lymphocytic leukemia (T-LGLL).
METHODSA retrospective analysis of the clinical presentation, bone marrow morphology, immunophenotyping and T-cell receptor gene rearrangement status were performed in 19 patients with T-LGLL.
RESULTSOf 19 patients, the most frequent hematological abnormalities were anemia and neutropenia (16/19 and 17/19 patients, respectively). Large granular lymphocytes (LGLs) were observed in 17 of 19 peripheral blood smears and 15 of 19 bone marrow aspirate specimens. Lymphocytosis (> 0.2) was present in 17 of 19 patients in their bone marrow aspirate specimens. Bone marrow biopsy specimens revealed lymphocytosis in 16 cases, with a mild to moderate increase of lymphocytes observed in 12 cases (12/16). The pattern of lymphoid distribution was interstitial in bone marrow sections. Intravascular distribution was seen in 8 cases. Lymphoid nodules were present in 4 cases. Flow cytometery showed an immunophenotype of CD3(+) CD4(-) CD8(+) CD56(-) CD57(+) of the tumor cells in 13 cases. Of the other 6 cases, the immunophenotypes included CD8(-) (1 case), CD56(+) (2 cases) and CD57(-) (3 cases). Immunohistochemistry showed CD3+ (10/10), CD57+ (3/3), CD8+ (6/7), TIA-1+ (6/7), granzyme B+ (4/7), perforin + (1/7), CD4- (4/4) and CD56- (9/9). Clonal T-cell receptor γ gene rearrangement by PCR was detected in 12 cases (12/17).
CONCLUSIONSHematopathologic features of most T-LGLL are distinct. Morphologic, immunophenotypic and molecular analysis of both peripheral blood and bone marrow specimens are essential and complementary in the diagnosis and differential diagnosis of T-LGLL.

OBJECTIVETo study the characteristics histologic and cytologic features and clinical usefulness of plasma cell myeloma (PCM) subtyping according to WHO PCM classification.
METHODSBone marrow biopsy plastic-embedded sections were stained with H-G-E and Gomori's stains, and bone marrow aspirate smears were stained with Wright's stain. The clinicopathologic findings were then analyzed.
RESULTSOf the 131 cases with PCM, three types of growth patterns were noted: interstitial (21 cases, 16.0%), nodular (46 cases, 35.1%) and packed (64 cases, 48.9%). Besides, there were three cytologic subtypes: mature plasma cell type (43 cases, 32.8%), immature (81 cases, 61.8%) and pleomorphic (7 cases, 5.3%) types. The age of patients with mature plasma cell type was significantly higher than that of immature type (P = 0.005); and the number of tumour cells in bone marrow smears was significantly higher than that of immature type (P = 0.003). The numbers of WBC and platelets in peripheral blood were also significantly higher than that of pleomorphic type (P = 0.024, P = 0.002, respectively). On the other hand, the number of platelets in peripheral blood of immature type was significantly higher than that of pleomorphic type (P = 0.019). Marrow fibrosis was more frequently observed in immature type than in mature plasma cell type (P = 0.000). The incidence of marrow fibrosis and osteolytic lesions was higher in high risk group than in low risk group (P = 0.000, P = 0.023 respectively). Twenty-one cases (56.8%) of the 37 cases treated with MP or MP and M2 chemotherapeutic regimens showed good response. However, there was no significant difference in treatment response and survival between different subtypes.
CONCLUSIONSEach subtype of PCM carries different clinicopathologic features in some aspects. The classification carries important value in pathologic diagnosis and probably in predicting prognosis.
