1.MRI in the diagnosis and staging of lung cancer
Journal of International Oncology 2013;40(10):762-765
Magnetic resonance imaging (MRI),a commonly used imaging technique,has been extensively investigated in lung cancer diagnosis and staging.Many studies have demonstrated that MRI can be used for the differential diagnosis of benign and malignant pulmonary nodules and for the screening of lung cancer; it also has important value in TNM staging of non-small cell lung cancer (NSCLC),with equivalent sensitivity and specificity to 18F-fluorodeoxyglucose (18F-FDG) PET-CT,which suggests that MRI can be used as an alternative imaging modality in noninvasive diagnosis and staging of NSCLC.
2.Mechanisms of ultrasound affecting the chemotherapeutic sensitivity of Neuroblastoma cell
Journal of Chongqing Medical University 2007;0(07):-
Objective:To investigate the effect of ultrasound on the ultrastructure and expression of P-gp of Neuroblastoma cell in order to discuss the mechanisms of ultrasound affecting the chemotherapeutic sensitivity of SK-N-SH cell. Methods:The SK-N-SH cells were divided into the experimental group and the control group. In the experimental group,the cell suspensions were exposed to ultrasound irradiation. In the control group,the cell suspensions were exposed to sham irradiation . The changes of ultrastructure of tumor cells were observed by scanning electron microscope and the expression of P-gp in two groups were detected. Results:(1) In the pictures took by scanning electron microscope,we found that: the configuration of tumor cell changed and there were some holes of different diameters on the cell membrane and the numbers of microvillus reduced or disappeared after ultrasound irradiation.(2) The result of immunocytochemisty showed the expression rate of P-gp in SK-N-SH cells in the control group was 56.23%?9.86% vs 34.86%?6.19% in the experimental group (P
3.Diagnosis and treatment of spontaneous perforation of the bile duct in children
Journal of Chongqing Medical University 2007;0(12):-
Objective:To evaluate the etiology,elinic characteristics,diagnosis and treatments of spontaneous perforation of the bile duct in children. Methods:The clinical data of eight children with spontaneous perforation of the bile duct between 1998 -2006 were analyzed retrospectively. Results:5 of 8 cases were diagnosed bile duct perforativn before operation,all the patients recovered favorably after T-tube and pelvic drainage. 3 children complicated with choledochal cyst were cured afterⅡstage radical operation. Conclusions:the etiology of spontaneous perforation of the bile duct in children is unclear, panereaticobiliary confluence malfunction (PBCM) maybe the main reason. Peritoneocentesis is very important to the diagnosis, which is difficult in child preoperatively. The effective surgical treatments are T-tube and pelvic drainage. The children complicated with PBCM needⅡstage radical operation,and long term follow up are necessary for the children present with spontaneous perforation of the bile duct without PBCM.
4.Periopertive nursing of children with formaral angulation deformity treated with sreminobicular crib external fixator
Modern Clinical Nursing 2015;(2):25-28
Objective To summarize the perioperative nursing experience in nursing children with formaral angulation deformity treated with sreminobicular crib external fixator. Method The clinical data of 15 children with formaral angulation deformity treated with sreminobicular crib external fixator were reviewed. Results All 15 children got recovered, with the femora extended by 4~9 cm. After operation, all of them were affected by knee flexion dysfunction and foot drop to varied extents, which were improved satisfactorily after systematic training. Conclusions The systematic and progressive training can prevent knee flexion dysfunction and foot drop. Careful observation and effective nursing play an important role in the treatment of formaral angulation deformity.
5.The diagnosis progress of Meckel′s diverticulum
Chinese Journal of Applied Clinical Pediatrics 2015;(19):1518-1520
Meckel′s diverticulum is the most common congenital anomaly of the gastrointestinal tract. Most ca-ses are asymptomatic,while it can be symptomatic when complications happened,its complications often expressed as hematochezia,abdominal pain,vomit,fever,and so on. When signs or symptoms arise from a Meckel′s diverticulum, morbidity and mortality will increase. So make a definite diagnosis of the diverticulum play an important role in the treatment of Meckel′s diverticulum. In this essay,now illustrate the meaning of imaging examination about the diagnosis of Meckel′s diverticulum,wish to make a diagnosis as soon as possible.
6.Prenatal diagnosis and outcomes of fetuses with cutaneous hemangioma
Chinese Journal of Obstetrics and Gynecology 2000;0(09):-
Objective To study the ultrasonic characteristics of fetal cutaneous hemangioma and the association with perinatal outcomes.Methods Five fetuses with cutaneous hemangioma were detected by gray-scale and color Doppler ultrasound,compared with the result of pathology and hematology examinations after birth.Results Of the 5 cases diagnosed by ultrasound,3 had arteriovenous fistulas.In these 3 cases two fetuses developed high-output cardiac failure,and one developed cardiac insufficiency and thrombocytopenia.Finally one fetus was induced,one fetus died in the uterus and one neonate survived.The other two fetuses who had small tumors diagnosed by ultrasound did not develop any perinatal complications, and the neonates had favourable prognosis.Conclusions Massive hemangiomas are frequently associated with life-threatening complications such as high-output heart failure,thrombocytopenia and disseminated intravascular coagulopathy(Kasabach-Merritt syndrome).
9.Advances on clinical application of non-absorbable antibiotic rifaximin
Chinese Journal of Clinical Infectious Diseases 2014;7(3):282-286
Rifaximin as a representative of the non-absorbable antibiotics,has special effects and wide application prospects in treatments of acute intestinal tract infections,irritable bowel syndrome,inflammatory bowel disease,diverticulosis of colon,hepatic encephalopathy and so on.This paper reviews the advances on clinical efficacy and safety of rifaximin to provide reference for clinical use.
10.One case report of group B streptococcus infection caused neonatal purulent meningitis and subdural effusion
Journal of Clinical Pediatrics 2014;(7):658-659
Objective To discuss the early recognition and treatment of group B streptococcus (GBS) infection caused neonatal meningitis and subdural effusion. Method The onset, clinical manifestations, diagnosis and treatment process were retrospectively analyzed in one case of typical GBS infection caused neonatal meningitis and subdural effusion. Results The subject was late-onset GBS infection, with insidious onset, rapid progress, slow clinical recovery, and highly sensitive to vancomycin. During the treatment, the subject had relapses. The subdural effusion had been found. After extension of vancomycin treatment, the subject recovered. Conclusions The late onset GBS infection should be taken seriously in clinical, pay attention to the complications such as purulent meningitis, subdural effusion, hydrocephalus, and be early treated with adequate and effective antibiotics.
