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.

ObjectiveTo discuss the value of immunochemical fecal occult blood test (IFOBT) in diagnosis of colorectal diseases.Methods Two hundred and fifty-one patients who taken IFOBT and chemical fecal occult blood test(CFOBT) from January 2008 to August 2011 were enrolled in this study.They were definitely diagnosed by total colonoscopy combined with pathology.ResultsThe positive rate of IFOBT and CFOBT in colorectal cancer patients was 100.0％(57/57) and 84.2％(48/57),there was significant difference (P ＜ 0.05).The positive rate of IFOBT and CFOBT in colorectal polyp patients was 38.6％ (32/83) and 10.8％(9/83 ),there was significant difference(P ＜ 0.05 ).The positive rate of IFOBT and CFOBT in inflammatory bowel disease patients was 100.0％(31/31) and 80.6％(25/31),there was no significant difference (P ＞ 0.05).Thepositive rate of IFOBT and CFOBT in non-specific enteritis patients were 86.8％ (33/38) and 73.7％ (28/38),there was no significant difference (P ＞ 0.05 ).The positive rate of IFOBT and CFOBT in normal colorectal cases was 2.4％(1/42) and 19.0％(8/42),there was siguificant difference (P ＜ 0.05).ConclusionsIFOBT is better than CFOBT in diagnosis of colorectal cancer and colorectal polyp.IFOBT has lower false positive rate.
