Objective:Discussing the laboratory findings and clinical features of the children with MDS.Methods:Analysing the results of peripheral blood,bone marrow and clinical manifestations in 13 patients with MDS.Results:All 13 patients were male.Main clinical manifestations include fever,anemia and hepatosplenomegaly.The anemia was of moderate to severe degree.Immature RBC were found in the peripheral blood smears.WBC ranged from high,normal or low.Immature peripheral blood cells were seen in 4 patients.The counts of platelets were normal or low.The bone marrow showed hyperplasia actively and abnormal erythropoiesis and/or myelopoiesis.The diagnosis in 10 patients was RA,2 patients,RAEB and 1 patient,RAEB-t.Conclusion:The diagnosis of MDS depends on the bone marrow examination.The bone marrow shows one abnormal hematopoietic system at least and must differentiate with other hematologic disorders.

Objective:To study the relationship between the laboratory behavior and clinical diagnosis as well as therapeutic efficacy of idiopathic thrombocytopenic purpura.Methods:The blood platelet count in peripheral blood,megakaryocyte count and classification in bone marrow smear and chromosome examination in bone marrow were executed respectively in 130 idiopathic thrombocytopenic purpura cases,whose therapeutic efficacy with IVIG and delta prenovis were observed.The blood clot retraction experiment was executed in 89 cases and the collecting function of platelets was detected in 28 cases.Results:There were 5 cases whose chromosome examination was abnormal in all 130 cases.After treated with IVIG and delta prenovis for 6～10 days,clinical symptoms of 89 cases were relieved obviously.Conclusion:The ITP patient who has more megakaryocytes in his bone marrow smear has the better therapeutic efficacy after treated with IVIG and delta prenovis,and the one with the little infantile megakaryocytes has the least therapeutic efficacy.

OBJECTIVE: To analyze the current situation and developing trend of drugs used in 10 hospitals of Hunan Province from 1996 to 2000, and to serve as reference for drug production, marketing and clinical application .METHODS:The sum of money and percentages of different kinds of drugs used each year were added up separately.RESULTS: The sum of money of drugs consumed was increasing at a rate of 18% each year.About 40% of the money was spent on anti - infective drugs and 20% on imported drugs.CONCLUSION: The sum of money of drugs consumed will grow year by year .The clinical use of drugs will be more rational and of more choices,but the sum of money spent on imported drugs will decrease.

Objective To investigate the clinical significance of antinucleosome antibody (AnuA) in the patients with lupus erythematosus (LE) through detecting the serum level of AnuA in different types of LE patients before and after treatment. Methods Enzyme-linked immunosorbent assay(ELISA) was used to detect the serum level of AnuA in 31 SLE patients, 26 SCLE patients, 7 DLE patients, 6 scleroderma patients, 5 dermatomyositis patients and 30 healthy controls. Among them, the serum levels of AnuA before and after treatment were detected in 15 SLE patients and 10 SCLE patients. Clinical data, laboratory test results and the scores of SLE disease activity index (SLEDAI) were analyzed with SPSS11.0 software. Results The serum levels of AnuA in SLE patients were higher than those in SCLE, DLE, scleroderma, dermatomyositis patients and healthy controls(P

Objective To evaluate the merits and demerits of three different closure methods for femoral artery access site in the interventional therapeutic procedures for senile patients with coronary artery disease. Methods We managed the femoral artery access sites in 60 cases undergoing interventional operation using three different hemostasias, including manual compression, Femostop equipment and Perclose suture (20 cases for each group). The procedure time, time for patients staying in bed, expenditure obedience, the percentage of procedure failure and vagal vascular reflex, and local vascular complications were observed and analyzed statistically. Results The study showed that the procedure time in Perclose suture group was about 12 minutes, much shorter than that in finger pressing and Femostop equipment groups (respectively 23 and 55 minutes, P

OBJECTIVETo observe the effects of moxibustion with different temperatures on cholesterol and skin around "Shenque" (CV 8) in mice with acute hyperlipidemia, and to explore the correlation between moxibustion effect and transient receptor potential vanilloid 1 (TRPV1).

METHODSEight mice among 32 mice of C57BL/6J wild type (WT) were selected into a blank group, and the remaining 24 mice were made into the acute hyperlipidemia model by injection of egg yolk. After model establishment, the mice were randomly divided into a model group, a 38 °C moxibustion group and a 46 °C moxibustion group, 8 mice in each group. The temperature was (38 ± 1) °C in the 38 °C moxibustion group and (46 ± 1) °C in the 46 °C moxibustion group. "Shenque" (CV 8) and "Zusanli" (ST 36) were selected in the two groups; moxibustion was given for 10 min per time, once a day for 2 times. Mice in the blank group and model group were treated with immobilization and moxibustion was not given. After treatment, the level of serum cholesterol was tested by oxidase method; the morphology of skin around "Shenque" (CV 8) was observed by HE staining; the expression of TRPV1 in skin was measured by immunohistochemistry.

RESULTS(1) Compared with the blank group, the level of serum cholesterol was increased in the model group (P < 0.001); compared with the model group, the level of serum cholesterol was reduced in the 46 °C moxibustion group (P < 0.001); compared with the 38 °C moxibustion group, the level of serum cholesterol was reduced in the 46 °C moxibustion group (P < 0.01). (2) There was slight change of morphology and structure in skin tissue in the 38 °C moxibustion group, while obvious change was observed in the 46 °C moxibustion group, indicating specific change. (3) The difference of the expression of TRPV1 in skin was significantly different between 46 °C moxibustion group and blank group, model group (both P < 0.01); it was also different from the 38 °C moxibustion group (P < 0.05).

CONCLUSIONMoxibustion temperature is one of the important factors affecting the cholesterol and acupoint skin. The effects of moxibustion are related to TRPV1.

Objective:to investigate clinical significance of serum and urine NGAL (Neutrophil gelatinase-associated lipocalin) in the early kidney damage with primary hypertension.Methods:According to UAER ( urinary microalbumin excreting rate ) ,we divided 90 patients with primary hypertension into three groups (<30 mg/24 h,30-300 mg/24 h and >300 mg/24h),and selected 30 healthy people as the control group.Serum and urine NGAL and cystatin C ,serum creatinine,urea nitrogen,high sensitive C reactive protein , transferrin,and basis of blood pressure were detected and followed up one year.Results:Compared with healthy group ,GFR( glomerular filtration rate ) and serum NGAL were decreased significantly in medium and severe proteinuria groups , while urine NGAL was increased.Conclusion:Serum and urine NGAL have been a clear trend changes in kidney damage ,which could be used as a reliable indicator in monitoring renal function of patients with primary hypertension.

Objective We reported previously that single nucleotide polymorphisms SNP) + 11G ＞ A in intron 3 of the human urate transporter 1 (hURAT1) gene are associated with hyperuncaemia in Han Chinese.The aim of the present study was to evaluate the effect of the variants on hURAT1 function.Methods The wild-type,mutant-type hURAT1 and exon 5-null hURAT1 were constructed,and respectively microinjected into the zebrafish embryo yolks.The subcellular localization of different genotypes of hURAT1 was detected by confocal laser scanning microscope.Results Compared with wild type,the mutant recombinant plasmid transcribed two types of mRNA spliceosome,the wild type and the exon 5-null type.The hURAT1 wild type protein was prominent localized on cell membrane,while the mutant type and exon 5-null hURAT1 proteins were distributed uniform in the cytoplasm but not on the cell membrane.Conclusion The hURAT1 variant + 11 G ＞ A resulted in an alternative splicing of hURAT1 mRNA-exon 5-null type.Its protein product exhibited a different subcellular localization compared with that of wild type.
