Objective To explore the expression of p130Cas and c-erbB-2 in human breast carcinoma and the relationship between p130Cas and c-erbB-2 levels with clinical and pathological characteristics. Methods Immunohistochemistry SP staining was applied to detect the expression of p130Cas and c-erbB-2 in tumor tissues from 53 cases of human primary breast carcinoma,10 cases of breast fibroadenoma and in 10 cases of normal breast tissues. Results Breast carcinoma tissues showed higher levels of p130Cas and c-erbB-2 than normal and fibroadenoma tissues(both P<0.01).The expression of p130Cas was related with age, menopausal status, ER, PR status and histological grades, but not related with tumor size, lymph node status and pathological stages. The expression of c-erbB-2 was related with ER status, histological grades and lymph node status, but not related with age, menopausal status, PR status, tumor size and pathological stages. There were no significant correlations between p130Cas and c-erbB-2. Conclusion p130Cas and c-erbB-2 have relations with the malignant transformation and differentiation of breast carcinoma.c-erbB-2 is associated with metastasis of breast carcinoma.p130Cas and c-erbB-2 can be served as useful indicators in the prognosis of breast carcinoma.

Purpose: To explore the clinical value of 99mTc-MIBI imaging in differentiating malignancies from benign breast masses. Methods: 195 patients underwent the examination for 99m Tc-MIBI. Comparative diagnosis was done by postoperative pathology in all cases. Results: 69 of the 84 cases of breast cancer were preoperatively diagnosed by 99mTc-MIBI, the causes of false-negative results were small size of the mass and the higher degree of malignancy. 102 of the 111 patients with benign lesions were scintimammographically negative, the cause of false-positive results was large fibroadenomas with surplus blood supply. The sensitivity was 82. 1%, specificity was 92.0%, and the diagnostic accuracy was 89.2%. Conclusions: 99mTc-MIBI examination is an effective, simple and noninvasive diagnostic method for primary breast cancer.

12 ml/s was used as Group A and Qmax ≤12 ml/s as Group B. Results One week after removal of urinary catheter, dysury appeared in five cases with Qmax for (9.45?2.62) ml/s, of which two cases were with posterior urethral stricture, two with benign prostatic hyperplasia and one with weak detrusor contraction. Three months after removal of urinary catheter, six cases led to secondary dysuresia due to posterior urethral stricture and had Qmax for (6.28?3.26) ml/s, with significant difference compared with urodynamic parameters of normal group (P

Objective To study clinical manifestations,laboratory variables,imaging features and therapies of refractory Mycoplasma pneumoniae pneumonia (RMPP).Methods The retrospective analysis of clinical data was conducted in 45 children with RMPP and 74 children with Mycoplasma pneumoniae pneumonia (MPP)admitted to department of pediatrics.The general data,clinical manifestations,laboratory variables,imaging features and therapies were compared between two groups.Results As compared to MPP,the age(6.14 ±3.35)y,febrile days(9.49 ± 5.28)d,the hospitalized days(11.45 ±3.42)d were significantly higher than that of MPP group (P <0.001);RMPP had higher rations of unilateral pulmonary infiltration[41(91.11%)],large consolidation shadows[35(77.78%)], pulmonary[21(46.67%)]and extrapulmonary complications[24(51.33%)](P <0.05);CRP,ESR,LDH and IgM were increased,the difference was statistically significant (P <0.01);Thirty -seven cases(82%)of RMPP had to add ceftriaxone sodium,thirty -two cases(71.7%)of RMPP had to add glucocorticoid,,Bronchofiberoscope lavages were used in six cases of RMPP.Only one case of RMPP occured sequela.Conclusion The older children,the per-sistent high fever,large consolidation shadows of pulmonary,pulmonary and extrapulmonary complications,high level of serum CRP,ESR,LDH and IgM are the clinical related factors of RMPP.The combination of cephalosporins and (or)glucocorticoid might consider for the cases who have no effect with macrolides.The effect is sure for RMPP with Bronchofiberoscope lavages.

It is a common phenomenon that medical research is out of line with clinical work at present. In fact, there is intrinsic interrelation between clinical work and research. Thinking and exploration at clinics are part of the research, and any research based on chnical work not only has great value, but also receives strong support from the state. However, to translate clinical research into clinical practice is difficult, which requires evidence-based methodology, a knowledgable team with persistence andtechnologies, et al.

Tooth agenesis constitutes one of the most common developmental anomalies in man. Oligodontia is defined as congenital absence of six or more teeth. Based on the studies of our team in cooperation with Peking University Center for Human Disease Genomics in the past five years, this article reviews the current research progress in clinical phenotypes and case collection, epidemiological investigation and etiological genetic studies of oligodontia. The symptoms of oligodontia were classified into syndromic and non-syndromic according to the occurrence of tooth agenesis with or without systemic developmental defects. As for the advancement of theories and techniques of molecular genetics, a number of gene mutations have been identified to be the direct etiological factors causing some specified diseases, especially those with developmental defects. Here, this article summarized the outcomes of molecular genetic study of some cases we collected. Of the systemic oligondontia patients, a new four-base-deletion mutation in PITX2 was identified in a large kindred with typical symptoms of Rieger Syndrome; four different gene mutations in ED1 casing X-linked hypohidrotic ectodermal displasia were found in five nucleus families. Compared with the former, non-syndromic oligodontia has more genetic heterogeneity rather than some specific virulence gene. PAX9 and MSX1 are the identified genes associated with family tooth agenesis without systemic syndrome. Also, in our research, three gene mutations in CBFA1 were detected in four cleidocranial dysplasia families, which is a systemic developmental disease including the symptoms of tooth eruption abnormality and accessory teeth.

Clinical data and treatment of a patient with late-onset glutaric acidemia type Ⅱ who was admitted to the Department of Pediatric Intensive Care Unit (PICU) of Shenzhen Children′s Hospital were retrospectively analyzed.The patient is a female with the clinical manifestations of aggravated progressive proximal muscle weakness, accompanied by vomiting, abdominal pain and liver enlargement.A marked increase of transaminase, bilirubin and creatine kinase was detected, and hyperammonemia, hypoglycemia and metabolic acidosis were also observed in the patient.Blood amino acids and acylcarnitines spectra showed increased levels of various acylcarnitines.The muscle biopsy study suggested lipid storage myopathy (LSM), and the genetic test identified a homozygous mutation in the electron transfer flavoprotein dehydrogenase (ETFDH) gene.After treatment with Vitamin B 2, carnitine, coenzyme Q10 and plasma exchange, the motivate ability and biochemical parameters of the patient returned to normal.For patients with aggravated progressive proximal muscle weakness, hepatic dysfunction and increased serum creatine kinase levels, late-onset glutaric acidemia type Ⅱ should be considered.The key to early diagnosis and treatment of the disease is to improve the knowledge of it.

In recent decades, with the development of electrophysiological and neuroimaging techniques, the researchers found that spinal cord injury (SCI) not only caused pathological changes in the spinal cord, but also in the brain. This paper reviewed the influence of SCI on the structure and function of the brain in terms of brain neuron degeneration caused by SCI, the changes of neurotrophic factor in brain, and the side-effects of medicine.
