This paper is aimed to evaluate the CT manifestation of congenital pectus excavatum and its effect on the cardiac morphology. CT features of 34 children with pectus excavatum were retrospectively reviewed. The Haller index (HI), CT depression index (CTDI), cardiac rotation angle (CRA), pulmonary vein angle (PVA), cardiac compression index (CCI) and cardiac asymmetry index (CAI) were measured from the images on the PACS system. The relationships among these indexes were evaluated. The HI was 4.12 +/- 1.48, the CTDI was 2.39+/- 0.70, CRA was (53.52 +/- 7.68) degrees, PVA was (66.51 +/- 11.02) degrees, CCI was 2.43 +/- 0.95, and CAI was 1.55 +/- 0.56. There was statistical significance of CCI and CAI between children with severe or slight pectus excavatum. The HI and CTDI were positively related with CCI and CAI respectively, whereas there was no statistical significance of CRA and PVA between children with severe or slight pectus excavatum. There was no statistical significance of HI, CTDI, CRA, PVA, CCI and CAI among different age groups. The morphological change of the heart compressed in children with pectus excavatum can be accurately evaluated by multislice helical CT.

OBJECTIVE To investigate probationer nurses' knowledge about nosocomial infection (NI) and clean operating-room. METHODS Survey among probationer nurses was performed by self-designed questionnaires. RESULTS 47% probationer nurses thought it very necessary to strength knowledge about NI before probation. The scores of clean operating-room knowledge was lower than that nosocomial infection (NI); The cognition rate among high educated probationer nurses were higher than low educated,P

Objective To explore the effect of methylprednisolone combined with high dose immunoglobulin (IVIg) in treatment of severe bullous skin disease. Methods 51 cases of severe bullous skin diseases were randomly divided into control group and observation group and control group received conventional methylprednisolone treatment on the basis of the observation group in this high-dose injection combined with IVIg,therapeutic effect were observed.Results The observation group hospitalization days ( 15.6 ± 6. 2) d, hormone usage ( 87. 6 ± 13.7 ) mg, hormone reduction time(8. 6 ±2. 4) d,were obviously lower than the control group(23. 1 ±6. 3)d,( 105.3 ± 1.64) mg, ( 13.8 ±4. 1 ) d ( t = 2. 771,3. 102,3. 219, P ＜ 0. 05 ). The observation group total effective rate was significantly higher than the control group( x2 =6. 248,P ＜0. 05). The observation group therapy effect-acting period and obviously subsidise lesions time was(8. 9 ±2. 4)d, (17.6 ±3. 7)d respectively,were significantly lower than the control group( 13. 1 ±3. 8) d, (23. 6 ± 5. 1 ) d, the differences between the two groups were statistically significant ( t = 2. 893,3. 347, P ＜0. 05). The observation group complication occurred in 5 cases were lower than those of the control group of 9 cases (x2 = 5.245 ,P ＜ 0. 05 ). Conclusion Methylprednisolone combined with high dose IVIg treatment of severe bullous skin disease could shorten the course and speed up the restoration of skin lesions, reduce and alleviate the glucocorticoid dosage and side effects, improve the cure rate , and it was worthy of promotion.

tep immunochromatographic method accounted for 96.4%.Conclusion Both RT-PCR and step immuno chromatographic method can not be used as means of short-term therapeutic effect evaluation.

Objective　To summarize the phenotypic and genotypic characteristics of mitochondrial combined oxidative phosphorylation deficiency type 1 (COXPD1), and to improve the clinicians' awareness of this mitochondrial encephalomyopathy. Methods　The clinical characteristics, physical examination, laboratory examination and other data of a child with COXPD1 were analyzed retrospectively. The diagnosis was confirmed by clinical whole exon sequencing and high-precision mitochondrial genome full-length PLUS gene detection, and the phenotype and genotype were analyzed by reviewing relevant literature. Results　A one-year and five-month-old boy mainly presented with hyperlactacidemia and abnormal liver function. Clinical whole exon sequencing showed that the child had homozygous variation of c. 688G>A(p.G230S) in the GFM1 gene. Sanger sequencing verified that the variation was respectively inherited from the parents of the child (both were heterozygous) with the autosomal recessive inheritance pattern. The high-precision mitochondrial genome full-length PLUS detection also did not find pathogenic mutations related to clinical phenotypes. The child was diagnosed with COXPD1. After "cocktail" therapy and liver protection therapy, the patient's condition improved. Conclusions　The phenotype of COXPD1 is complicated and variable, mainly liver type and brain type. The mutation of GFM1 gene affects mitochondrial translation system function, and early gene detection is helpful for definite diagnosis.

Objective To observe the effect of maternal deprivation(MD)on learning and memory ability and hippocampal pathology and nestin expression in rats with hypoxic -ischemic brain damage (HIBD).Methods The models of HIBD SD male rats were established by the method of Rice,and were randomly divided into 2 groups:MD group and control group.In addition,the sham -operation group(sham group)models were established.The MD group rats were separated from their mother 3 hours per day from the second day after modeling to the 21 st postnatal day.After 28 postnatal days,Morris water maze was used to evaluate the learning and memory ability of the rat models.HE stai-ning was employed to observe the hippocampal pathological change in the rats.Then,the expression of nestin in the hip-pocampus was measured by the method of immunohistochemistry.Results Their body mass changes showed that quali-ty of sham group was higher than that of the control and the MD groups,and quality was improved in the control group, compared with the MD group,and the differences were statistically significant(q =9.860 8,3.880 7,5.980 1 ,all P <0.05).The water maze scores of the MD group in place navigation test and spatial probe test were much lower than that of the control group and the sham group,and the scores of the sham group were higher than that of the control group,the differences were statistically significant(all P <0.05 ).The findings of HE stain showed that the pathology in the right -sided hippocampus of the sham group was normal and neurons were well -arranged,and that of control group was minimally abnormal,and the neurons were almost arranged orderly and remained normal.While,the pathomorpholo-gy of the MD group was obviously abnormal,the neurons were arranged disorderly,many of the neurons lost.According to the immunohistochemical findings,the number of nestin -positive cells in right -sided hippocampus of the MD group was significantly less than that of the control group,and the number of nestin -positive cells of the sham group was less than that of the MD group,which showed significant differences among the groups(all P <0.05).Conclusions MD aggravated injury to learning and memory ability of neonatal rats with HIBD,and decrease the number of nestin -posi-tive cells of MD markedly,which is not good for the recovery of brain injury.

Objective To investigate the application of colposcope in cervical cancer screening in Yunnan ethnic minority areas.Methods The questionnaire survey was conducted on 641 women,and the data of the colposcopy and biopsy were reviewed retrospectively.The colposcopy and pathological diagnosis results were compared.Results The minority women thought colposcopy more acceptable was 78.64％ (383/487).The colposcopy found suspected low-grade cervical lesions were 377 cases,high-grade cervical lesions were 245 cases,cervical condyloma were 15 cases,cervical cancer were 4 cases.The pathological results:278 cases of cervical intraepithelial neoplasia (CIN) Ⅰ,174 cases of CIN Ⅱ,55 cases of CIN Ⅲ,15 cases of cervical condyloma,4 cases of cervical cancer.The consistent rate of colposcopy and pathological examination was 68.17％ (257/377) in low-grade lesions,89.39％ (219/245) in high-grade lesions,cervical cancer and cervical condyloma was entirely consistent.Conclusions The colposcopy is more easily accepted in Yunnan ethnic minority areas,which could be a preliminary diagnosis of cervical lesions,cervical condyloma and cervical cancer.It has an important clinical application value in diagnosis of cervical diseases.
