Objective To investigate clinical characteristics of the multi-center breast DCIS (ductal carcinoma in situ), in order to improve the rate of early diagnosis. Methods Clinical data of 23 multi-center breast DCIS patients admitted and operated on from September 2003 to February 2009 at our department were retrospectively reviewed. Results There were 4 cases associated with nipple discharge,and 18 cases with preoperative negative physical examination (78%). In the preoperative examination within 6 months, the positive rate of mammography was 90% mainly characterized by the existence of diffuse and multiple small calcifications. The positive rate of MRI was 25%, B ultrasound had no positive findings. The patients that were confirmed multi-center breast DCIS by intraoperative frozen section examination received mastectomy and ipsilateral axillary L1, L2 lymph node dissection. Conclusion The diffuse and multiple small calcification is one of early clinical characteristics of multi-center breast DCIS. Although the disease has a wide range of lesion, it still is an early tumor, and has a favourite prognosis after comprehensive treatment.

OBJECTIVETo analyze the factors which influence the safety and prognosis of aorta replacement combined with coronary artery bypass grafting (CABG) for thoracic aortic aneurysm associated with coronary artery disease.
METHODSFrom May 1982 to October 2002, 67 patients with thoracic aortic aneurysm were admitted, and 24 of them combined with CABG. Of the 24 patients, 9 received descending aorta replacement combined with CABG, and the other 15 received the ascending aorta replacement combined with CABG. The treatment results were compared with the other 43 patients only undergoing the thoracic aortic replacement.
RESULTSThe mortality rate of the patients with aorta replacement combined with CABG was 13% (3/24). Though the descending aorta replacement combined with CABG could make the cardiopulmonary bypass time and selective cerebral perfusion time longer, (278 +/- 54) min and (188 +/- 59) min respectively, no significant difference was observed in postoperative complications, 3-year survival rate, 3-year-cardiac-event-free rate compared with the patients only undergoing the thoracic aortic replacement (P > 0.05).
CONCLUSIONSThe aorta replacement combined with CABG can be performed safely, and the revascularization for coronary artery disease is useful for preventing occurrence of cardiac events.

By analyzing the epidemiological and clinical features of adenovirus in children with acute respiratory tract infection (ARTI), we provide a theoretical basis for early clinical diagnosis and treatment. Nasopharyngeal secretions were collected from 3480 children with ARTI, who were hospitalized at the No. 2 Hospital of Changzhou from January 2011 to December 2012. Adenovirus were detected using direct immunofluorescence assays. A total of 80 samples were positive for adenovirus (2.30%). The rate of adenovirus infection during 2011 was significantly higher than that in 2012, and the infection rate was higher in summer and autumn than in winter and spring. The infection rate was 1.14% among children aged < 1-year-old and the rates were higher among children in other age ranges. Adenovirus was found to be an important ARTI pathogen in children in Changzhou, mainly affecting children older than 1 year. ADV infections have various clinical presentations, but affected children tend to be severely ill with poor outcomes.

OBJECTIVETo study and compare the prophylatic efficacy of levetiracetam, valproate and phenobarbital on febrile convulsions in rats.
METHODSSixty Wistar rats were randomly administered with levetiracetam (200 mg/kg), valproate (250 mg/kg), phenobarbital (30 mg/kg) or normal saline (8 ml/kg) for 5 days. Five days later, febrile convulsions were induced by hyperthermal bath (45 Celcius degree). The latency, duration and the severity of seizures were observed.
RESULTSIn all the three drug-treated groups, the latency was significantly prolonged, and the duration and the severity of seizures were notably reduced compared with the saline group (P<0.05 or 0.01). The phenobarbital group had the shortest duration of seizures and the least severe seizures among the three drug-treated groups. There were no significant differences between the levetiracetam and valproate groups.
CONCLUSIONSContinuous administration of levetiracetam, valproate or phenobarbital is effective in preventing recurrent febrile convulsions in rats. Phenobarbital appears to be more effective than levetiracetam and valproate. There were no significant differences in the prophylactic efficacy between levetiracetam and valproate.

OBJECTIVETo study clinical effects of the over-articular external fixator combined with limited internal fixation for the treatment of Pilon fractures caused by high energy.
METHODSFrom September 2003 to April 2011, 36 patients with Pilon fractures caused by high energy were treated with the over-articular external fixator combined with limited internal fixator. There were 25 males and 11 females, ranging in age from 16 to 72 years old,with an average of 38 years old. The diagnoses of all patients were determined by conventional X-ray examination or three-dimensional spiral CT examination. The AOFAS scoring criteria was used to evaluate the therapeutic effects. The patients with comminuted fractures were treated with screw or Kirschner wire fixation without uncovering periost so as to enhance stability between fracture end and bone blocks,followed by the fixation with over-articular external fixators.
RESULTSAll the patients were followed up, and the duration ranged from 4 to 27 months, with an average of 13 months. Thirty-two patients got wound healing at the first stage. And the bone union duration ranged from 2 to 6 months, with a mean of 3 months. According to the AOFAS ankle-hindfoot subjective scoring standard, 13 patients got an excellent result, 20 good and 3 fair, with an score of 88.2 +/- 3.6. Twelve patients had infections at pinhole, 5 patients had pinhole pain. One patient had the fixator broken induced by over loading, who was cured after treatment. There were no complications such as nerve or vascular injuries, or osteomyelitis.
CONCLUSIONThe over-articular external fixation combined with limited internal fixation for the treatment of Pilon fractures caused by high energy is an ideal method, which has such advantages as reliable fixation, simple operation, coincidence with principles of biomechanical fixation, and benefit for fracture healing.

Objective To investigate the clinicopathological significances of LDHA/mutant p53 co-expres-sion in gliomas. Methods According to the 2016 WHO CNS,archived 68 gliomas were collected and analyzed retrospectively. The co-expression of LDHA/mutant p53 was detected by immunohistochemical staining. Results High expression of LDHA alone was always found in high grade gliomas(48.5%). Mutant p53 high expression was usually observed in glioblastomas (26.5%). There was a close relationship between co-expression of LDHA/mutant p53 in glioblastoma(27.9%,P = 0.005),or gliomas with high histological grading(27.9%,P = 0.002). Conclusions Co-expression of LDHA/mutant p53 in tumor cells might be a specific immunohistochemical pheno-type of gliomas,and may help for distinguishing glioblastoma and other high grade gliomas from low grade gliomas.
