Objective To study the changes of interleukin-4(IL-4),IL-6,IL-8 in children with idiopathic thrombocytopenic purpura(ITP).Methods The serum of IL-4,IL-6,IL-8 in 35 ITP patients and 20 normal control children were detected by enzyme-linked immunosorbent assay.Results The serum IL-4,IL-6,IL-8 in ITP patients were elevated. There were significant difference between ITP group and control group(P

Objective To study changes and effects of transforming growth factor-?1(TGF- ?1) and its receptorIII (TGF-?1 R III) in children with idiopathic thrombocytopenic purpura (ITP). Methods Bone marrow were respectively collected from 28 children with acute idiopathic thrombocytopenic pupura(AITP),16 children with chronic idiopathic thrombocytopenic purpura(CITP) and 20 comparably normal children; Percoll density gradient and immunomagnetic beads methods were used to purify megakaryocytes from bone marrow; ABC- ELISA was used to detect TGF - ?1 in bone marrow; in situ hybridization was used to detect TGF-?1 RIIImR-NA expression on megakaryocytes.Results In AITP and CITP group, the levels of TGF-?1 and TGF-?1 RIIImRNA were significant higher than those in control group(P

Objective To study the pathological characteristics of skeletal muscle in patients with polymyalgia rheumatica(PMR).Methods Thirteen patients were diagnosed PMR according to the diagnostic criteria described by Bird in 1979.The onset of disease was between 49-78 years of age (median 60.3 years).All of them showed continuous symmetric myalgia with markedly elevated erythrocyte sedimentation rate(ESR).Five patients had mild fever and 8 patients had elevated C-reactive protein(CRP).Electromyogram(EMG)showed myogenic pattern in 2 patients.Only 1 patient showed anemia and 2 patients had mild elevated creatinine phosphokinase.None of them showed evidence of temporal arteritis.Biceps brachii muscle biopsies were performed in all patients before corticosteroid therapy.Results The typeⅡmuscle fiber atrophy was observed in all patients.Moth-eaten changes appeared in 8 cases,increased intramuscular lipid drops in 8 cases and ragged red fibers(RRF)in 3 cases of them.After steroid therapy,all patients showed improvement of myalgia and normal ESR as well as CRP.Conclusions The main symptoms of the patients are myalgia and abnormal ESR.Some patients have high level of CRP and abnormal EMG.Anemia and temporal arteritis are less frequent.The main myopathological changes were typeⅡmuscle fiber atrophy.Some patients have moth-eaten changes.More lipid drops and RRF indicate abnormal metabolism of skeletal muscle.

Objective To explore the relationship between X - linked spondyloepiphyseal dysplasia tarda (SEDL) gene escaping X chromosome inactivation( XCI) and SEDL phenotype. Methods RT - PCR was performed on total RNA which was isolated from blood samples of patients, female carriers and controls. Patients and female carriers were selected from the pedigree with SEDL caused by the mutation (IVS2 - 2A→C) of the gene. cDNA was analyzed by polyacrylamide gelelectrophoresis(PAGE). Results PAGE data indicateed that female carriers expressed both normal and mutant SEDL mRNA,meaning the SEDL gene escaping XCI. Family investigation showed carrier females in the SEDL pedigree presented no symptoms. Conclusions The SEDL gene escaping X chromosome in-activation is firstly identified from human body. This may explain that carrier females present no symptoms.

OBJECTIVETo observe the clinical effects of two different circumcision procedures with the Shang Ring and compare their advantages and disadvantages.

METHODSA total of 527 adult males with phimosis or redundant prepuce underwent Shang Ring circumcision by conventional outward replacement (n = 254) and inward placement (n = 273), respectively. We observed the in-ring nocturnal pain, complications, ring-removal pain, degree of edema, recovery time, and patients' satisfaction after surgery, and compared them between the two groups.

RESULTSCompared with the conventional outward placement (5.9%) of the Shang Ring, the inward placement method showed the advantages of mild in-ring nocturnal pain, a low complication rate, significantly reduced ring-removal pain, and mild edema, but exhibited longer healing time.

CONCLUSIONIn Shang Ring circumcision for phimosis and redundant prepuce in adult males, each of the outward and inward placement methods has advantages and disadvantages of its own, but the latter is more advantageous and feasible.

Rice straw degradation with white rot fungi and cellulose multienzyme was studied. The results indicated that the LiP, MnP activity produced by P. chrysosoporium 172 could reach 28.3U/g and 12.6U/g respectively under suitable culture condition. And the lignin was degraded efficiently in contrast with the cellulose and hemicellulose in rice straw solid fermentation. Following treatment with white rot fungi, using multienzyme produced by A. niger NL-1 could greatly accelerate the decomposition of rice straw. The decomposition rate of cellulose, hemicellulose, lignin and the loss rate of dry material were 53.8%,57.8%,44.5% and 46.3% respectivity when hydrolysis rice straw 48h with cellulase multienzyme (including 3 IU /g rice straw) after culture P. chrysosoporium 172 for 10 days. Scanning electron microscope analysis showed the cell wall of rice straw was destroyed severely, and the whole tissue got loosely. These results demonstrated the rice straw had been decomposed efficiently and completely.
