Objective To make a further understanding of mammographic features of simple cyst of the breast (SCB).Methods Molybdenum target radiographic signs in 39 cases with SCB proved pathologically and were retrospectively analyzed. Results Of the 56 SCB in 39 cases, 23 were diagnosed rightly as SCB, 10 as fibroadenoma, 2 as cancer and the remaining 4 were undefined. The diagnostic accuracy and misdiagnosis were 59.0% and 41.0% respectively. Radiograph showed round in 12, ovoid in 38, mild lobed in 4 and comet tail form in 2. The borders of cyst were distinct and sharp in 26, distinct partly and indistinct partly in 27,indistinct completely in 3. The density was homogeneous in 54 with calcifications in 2. Of the 56 SCB, the length axes of cyst were upright to chest wall in 20 and towards nipple in 18. The cysts could be transformed with pressure in 4.Conclusion Careful analysis of radiographic features of SCB is helpful for diagnosing accurately this disease.

The course of fundamental operations in surgery is an important part of surgical teaching.It helps students to adapt to surgical practice quickly.During the teaching,there are some ways to improve teaching efficiency and quality,such as to know the new Chinese-English teaching material,the teaching purpose,the training of basic skills and aseptic principles of operation,the examination reform and regular teaching summery.

OBJECTIVESTo evaluate the clinical application of one-stage repair of hypospadias using pedicled penis and scrotal septal symphysis skin flap.

METHODSOne hundred and forty-nine cases of hypopadias were treated with the skin flap and followed up.

RESULTSAfter the operation, one hundred and twenty-two cases of patients obtained satisfactory outcomes, twenty-seven cases happened urethral leakage and preputial uredema were observed, and three cases suffered from urethral-skin fistula.

CONCLUSIONSThis technique was an optimal choice to penis hypospadias, Penoscrotal hypospadias and light-duty scrotal hypospadias. It was simple and convenient and could prevent infection but manage of drain must be done postoperatively.

Inflammasomes are high-molecular-weight, multiprotein complexes in cells, which are assembled after cytoplasmic nucleotide-binding oligomerization domain like receptors (NLRs) sense pathogens and danger signals. The inflammasome can activate caspase-1, and later makes the pro-IL-1β, proIL-18 precursor mature by cleavaging, thereby mediates the innate immunity. Dysregulation of inflammasomes plays an important role in the development of sepsis and other immune inflammatory diseases, thus inflammasome may be a new target for prevention and treatment of sepsis.

Single clones of Leptospirillum ferrooxidans were obtained on bilayer solid medium plate by incorporating Het-erotroph Acidiphilium SJH into the underlayer broth medium. The morphologies of the bacteria were investigated using electronic microscope.

Objective To investigate the association of platelet activating factor acetylhydrolase(PAF-AH) activity in children with primary nephrotic syndrome(PNS).Methods The plasma PAF-AH activity was measured in 78 children with PNS who were divided into 3 groups:steroid-responsive nephritic,steroid-dependent nephritic,steroid-resistent nephritic,after they had been given steroid for 6 months.The plasma PAF-AH activity were also measured in 60 healthy children at the same age,with spectrophotometric assay,at the ame time,the blood cholesterol was measured.Results The blood cholesterol has positive correlation with the plasma PAF-AH activity,there was no significant difference of the blood cholesterol among 3 groups in nephrotic syndrome children,there was a significant difference in the plasma PAF-AH activity among 3 groups in PNS children,but there was no significant difference in the plasma PAF-AH activity between the groups of steroid-responsive nephritic and healthy children.Conclusion Plasma PAF-AH activity is related to the sensibility to steroid treatment in children′s PNS,and the plasma PAF-AH activity in steroid-resistent nephritic is higher than steroid-dependent nephritic.It is a question that if gene mutation is related with PAF-AH activity.

Objective To release the correlation of point mutation of platelet activating factor acetylhydrolase(PAF-AH)gene and primary nephritic syndrome (PNS).Method According to the effect of hormonal therapy,94 children with PNS were divided into three groups:steroid-sensitive nephritic syndrome(SSNS),steroid-resistent nephritic syndrome(SRNS),steroid-dependent nephritic syndrome(SDNS).The point mutation of PAF-AH gene (G994T) were identified by molecular biology technique in children with PNS and 239 healthy children were set as control group.Results No statistics differences were found relating to the genotype and allele frequencies between patients with PNS,SSNS,SRNS and normal controls.But it is confirmed that the genotype and allele frequencies among patients with nephritic type nephritic syndrome (NTNS)was higher than patients with simple type nephritic syndrome(STNS) and normal controls.SDNS was higher than both SSNS and normal controls.The number of relapses during the first year after onset was significantly higher in the patients who were heterozygous for the mutant allele (GT) or homozygotes (TT) than in those of the GG homozygotes.Conclusion Most PNS children with PAF-AH gene mutation occurred at position 994 were NTNS.The risk of relapse during the treatment period was higher in patients with PAF-AH gene mutation occurred at position 994.

OBJECTIVETo observe the effect of Pingchuan Mixture (PCM) on plasma eosinophil cation protein (ECP), interleukin-5 in bronchial alveolar lavage fluid (BALF) and inflammatory cell count in experimental guinea pigs with asthma.

METHODSThe eosinophil, neutrophil, lymphocyte count were conducted by conventional method, IL-5 was detected by ELISA and ECP determined by RIA.

RESULTSLevels of eosinophil, neutrophil, lymphocyte, ECP and IL-5 after treatment were significantly lower than those before treatment, the difference between groups treated respectively by PCM, aminophylline, dexamethasone and Dingchuan Zhike Tablet was insignificant.

CONCLUSIONPCM could treat asthma by reducing the inflammatory cell count, ECP and IL-5.
