Objective To evaluate the effect of staged repair for tetralogy of Fallot (TOF) associated with pulmonary artery hy- poplasty.Methods From June 1996 to June 2006,37 patients with TOF were operated on.There were 26 males and 11 females. Their age was 5 months to 17 years(mean 3.6 years) and weight was 4.6～38.0 kg.All patients were diagnosed as TOF with pulmo- nary artery hypoplasty by cardiac catheterization.The mean pre-operative arterial saturation of the patients was (68.2?6.5) %,Mc- Coon ratio was 0.95?0.26 (0.81～1.17) and Nakata index was 82.7?21.6(71.6～97.5) mm~3/m~2.At the time of the first surgi- cal procedure,17 patients underwent central aortopulmonary shunt,13 patients received modified Blalock-Taussig shunt in the left side and 7 patients had modified Blalock-Taussig shunt in the right side.Results There were no easly operative deaths and no late deaths after the first stage repair.Pleural effusion after shunt occurred in 5 patients.The mean arterial saturation was significantly increased to (91.3?10.4) %,P

Objective To investigate the impact of accountable and kindred-like nursing and the practice of quality care.Methods 100 primiparas who gave birth three months before the accountable and kindred-like nursing were selected as the control group,while 100 primiparas who gave birth three months after accountable and kindred-like nursing were selected as the observation group.Tow groups' understanding of health education knowledge and skills,satisfaction with nursing when discharged,nomination rate of the most satisfactory nurse and compliance behavior after discharged were compared.Results In the observation group,62 cases had fully understood,28 had basically understood and 10 had not understood the health education knowledge when discharged,while in the control group the numbers were respectively 30,56 and 14.In the observation group,75 cases had fully understood,19 had basically understood and 6 had not understood the health education skills when discharged,while in the control group the numbers were respectively 28,58 and 14.The understanding of health education knowledge and skills were much better in the observation group than in the control group,and the differences were statistically significant (x2 =21.13,44.40,respectively; P ＜0.05).After being discharged,the compliance behaviors including pure breastfeeding,newborn massage and baby swimming of the observation group were also better than the control group (49 vs 27,58 vs 27,47 vs 18,respectively),and the differences were statistically significant (x2 =9.93,20.14,19.16,respectively; P ＜0.05).There were no significant differences in infant buttock nursing between two groups (P ＞ 0.05).The satisfaction of nursing and nomination rate of the most satisfactory nurse were also much higher in the observation group (99 vs 93,82 vs 53,respectively),and the differences were statistically significant (x2 =10.86,19.17,respectively ;P ＜ 0.05).Conclusions Accountable and kindred-like nursing can enhance the effect of health education,compliance behaviors,so as to improve the satisfaction degree of puerperants and their families with nursing service.

OBJECTIVETo investigate the clinical characteristics of children with Castleman's disease and to improve doctors' awareness of this disease.

METHODSClinical characteristics of 5 cases with Castleman's disease were observed and analyzed and relevant reports in literature were reviewed.

RESULTS(1) All the five patients' histories were long, and the first symptoms of them were painless lymphnode enlargement, and all of them were at school age; 3 patients' abdominal lymphnodes were enlarged, mediastinum lymphnodes enlarged in 3 cases, cervical lymphnodes were involved in 3 cases; (2) The clinical subtypes: the disease in 3 cases was localized Castleman's disease (LCD), all of their pathological subtype was hyaline vascular variant (HV). The rest of them were multicentric Castleman's disease (MCD), whose pathology was plasma cell variant (PC), and both of them had a febrile symptoms; (3) The white blood cells, C-reactive protein and ferritin levels were all elevated to different extents. Four of them had viral infections, and their cellular immune function was abnormal; (4) The LCD patients' prognosis was good after the complete resection. There is no standard therapy for MCD, the available therapies include antiviral, immune modulatory regimens, CD20 B cell monoclonal antibody and chemotherapy, but the prognosis was worse than that of LCD.

CONCLUSIONSCastleman's disease is rare in children, which can be misdiagnosed because it has no specific manifestations. The prognosis depends on the subtype.

Objective To investigate nursing strategy for elder patients with PICC complicated with venous thrombosis.Methods Treating and nursing strategies for 31 elder patients with PICC complicated with venous thrombosis were evaluated,including braking limb elevation,observing vital signs.Subcutaneous injection of anticoagulant drugs were given for 8 to 30 days,and bleeding,chest pain,dyspnea,cough or hemoptysis were observed.Physical therapy were also applied and extubation were done in 2 to 3 times after treatment.Results All observed cases were extubated fluently without broken pipe,bleeding or shedding of thrombosis.Conclusions Timing of extubation is related with broken pipe and thrombosis.Unconscious elder patients who lie in bed need intimate observation.Some patients have no symptoms after thrombosis.Thus,carrying out ultrasonic examination periodically is helpful for elder patients with PICC for a long time.Furthermore,ultrasonic examination should be done before extubation to ensure safe extubation.

OBJECTIVEThis study explored the dynamic expression of the E3 ubiquitin-protein ligase gene, Arkadia, in response to carbon tetrachloride (CCl4)-induced liver fibrosis in a mouse model and investigated the differential expression that occurs following treatment with the anti-fibrotic bone morphogenetic protein-7 (BMP-7).

METHODSThirty healthy male imprinting control region (ICR) mice were randomly assigned to three groups: normal (control; n = 6), CCl4-induced model group (model; n = 18), and CCl4-induced model with BMP-7 treatment group (treatment; n = 6). The model group was further divided into three subgroups (n = 6 each) for analysis at 4, 8 and 12 weeks after fibrosis induction. Liver fibrosis was induced by hypodermic injections of 60% CCl4 /peanut oil (5 mL/kg) to the hind legs of mice two-times per week in alternating legs for a period of 12 weeks. At week 9, the treatment group of CCl4-induced mice were given an intraperitoneal injection of BMP-7 (300 pg/g) simultaneously with that day's hypodermic injection of 60% CCl4 /peanut oil, and then every other day for a period of four weeks. The pathological changes in liver tissues were observed after staining with hematoxylin-eosin (HE) and Masson's trichrome. Messenger RNA (mRNA) and protein expression of Arkadia in liver were evaluated using reverse transcription-polymerase chain reaction and immunohistochemistry and Western blotting, respectively.

RESULTSMouse models of liver fibrosis were successfully established by CCl4 exposure. Arkadia, Smad7 and TGF-beta1 mRNA levels were up-regulated in the model group in a time-dependent manner (vs. control group), and BMP-7 treatment led to significant down-regulation of the CCl4-induced expression of the three genes (vs. control group: F = 812.80, 451.46, and 998.96, respectively; P less than 0.01). At week 12, the mRNA levels of Arkadia, Smad7, and TGF-b1 were significantly lower in the BMP-7 treatment group than in the model group (t = 12.108, 18.737, and 16.364, respectively; P less than 0.01). Arkadia, Smad7, and TGF-b1 protein staining was weak in the portal area of control liver tissue. In contrast, the model group showed significantly stronger staining for all three proteins in the portal area and in the cytoplasm of liver cells. The staining of Arkadia, Smad7, and TGF-b1 proteins was significantly lower in the treatment group (vs. control group: F = 8.399, 609.690, and 900.561, respectively; P < 0.01). At week 12, the protein levels of Arkadia, Smad7, and TGF-b1 were significantly lower in the treatment group than in the model group (t = 23.438, 11.667, and 42.889, respectively; P < 0.01).

CONCLUSIONArkadia expression gradually increased along with the development of liver fibrosis but was suppressed by treatment with the anti-fibrotic factor, BMP-7.

ORF1 and ORF2 gene of porcine circovirus type 2 were cloned by PCR with the specific primers designed according to genome of PCV2 (AY035820). Following extraction and digestion, PCR products were subsequently inserted into universal transfer vector plECMV (deleted partial gE and gI of pseudorabies virus) to generate recombinant transfer plasmid pIEORF1-ORF2. The genomic DNA of PRV TK-/gE- /LacZ+ strain and pIEORF1-ORF2 were co-transfected into IBRS-2 cells with lipofectin, and recombinant virus TK- /gE- /gI- /ORF1-ORF2+ was selected by PCR with ORF1 gene and ORF2 gene primers respectively. The recombinant virus was analyzed with Southern blotting and Western blotting. The results indicated that ORF1 and ORF2 gene of PCV2 had been inserted into the genome of TK- /gE- /LacZ+ strain and the expressed ORF1-ORF2 fusion protein could react with PCV2 positive sera. Result of virus titers detection showed the insertion of ORF1 and ORF2 gene did not influence propagation of recombinant virus.

OBJECTIVETo investigate the diagnosis and differential diagnosis of extranodal Rosai-Dorfman disease.

METHODSTwo cases of extranodal Rosai-Dorfman disease were studied using hematoxylin-eosin, and immunohistochemical staining, along with a literature review.

RESULTSThe lesions of RDD were characterized by the presence of large histiocytes with emperipolesis, accompanied by infiltration of lymphocytes, plasma cells and other inflammatory cells. The large histiocytes had an abundant cytoplasm, pale to eosinophilic in appearance, positive for S-100 protein staining, with a vesicular nucleus and a small basophilic nucleolus in each cell.

CONCLUSIONSExtranodal Rosai-Dorfman disease is known as an idiopathic proliferative disease of histiocytes with a distinct morphologic feature and is very rare. Differential diagnosis from other types of fibrohistiocytic proliferation lesions is recommended.
