Purpose Placenta accreta is a rare but severe pregnancy complications, and imaging diagnosis is always difficult. This paper aims to analyze the MRI manifestations of placenta accreta, and explore its misdiagnosis reasons. Materials and Methods A retrospective study was carried out on the findings and classification of MRI plain scan and diffusion weighted imaging (DWI) scan of 18 patients with placenta accreta confirmed surgically and pathologically. Results The prenatal MRI scan reported 15 patients of placenta accreta correctly (83.33%), and missed 3 (16.67%) among which 2 were with placenta accreta and the other 1 with placenta increta. The MRI of placenta accreta presented rather thin muscular layer, discontinuous junctional zone, and some unclear boundary of placenta and uterine wall; the signal of the placenta was heterogeneous, and we could see enlarged vessels of extremely low signal on T2 HASTE and high signal on TruFISP sequences, and low signal of thick intraplacental band; moreover, hematoma with high intensity on T1WI and low intensity on T2WI could be seen. DWI demonstrated uneven intensity and dark thicker intraplacenta bands in 2 cases. Conclusion As an important clinical auxiliary tool in diagnosing placenta increta, MRI has high accuracy in the diagnosis of placenta increta and placenta percreta; however, it has rather low accuracy in placenta accreta.

Objective To evaluate the effects of breastfeeding behavior through the implementation of family-centered empowerment education in primiparas.Methods According to random digit table,128primiparas in our hospitals were divided into the experimental group and the control group with 64 cases in each group from August 2014 to April 2015.At last 58 patients in the observation group and 59 patients in the control group completed the research.Those primiparas in the experimental group were given the familycentered empowerment education.The control group received conventional methods.Results The scores of breastfeeding self-efficacy,perceived social support and breastfeeding behavior of primiparas in the experimental group were 129.64±12.94,58.94±8.97,89.84±11.32,higher than the control group,101.78±78.67,50.27±10.56,71.56±12.03,the differences had statistical significance between two groups,t=9.656-10.487,P ＜ 0.05.Conclusions Using the family-centered empowerment education can effectively improve the breastfeeding self-efficacy,perceived social support and breastfeeding behavior in primiparas.

Objective To discuss the sedative and hypnotic effect of Jiaotai Pills on insomnia in PCPA rat model .Methods The PCPA ( PCPA acid) rats insomnia model was established, and the rats were divided into the model group, high, middle and low dosage of Jiaotai Pills group, and diazepam positive control group.The high performance liquid detective method was adopted to observe the effect of Jiaotai Pills on rat insomnia and hypothalamus neurotransmitters 5-HT and GABA.Results Compared with the model group, there existed significant difference in the insomnia state of rats and the central neurotransmitters 5 -HT in the high and middle dosages of Jiaotai Pill group and diazepam group.However, in the comparison of the high and middle dosages of Jiaotai Pill group and the model group, there was no significant difference in GABA in the central nervous system .Conclusion Jiaotai Pills has sedative and hypnotic efficacy.Its mechanism may be related to the effects of central neurotransmitter 5 -HT.Its relationship with GABA in the central nervous system is not obvious.The research has significant influence on the further development of Jiaotai Pills.

Objective To compare the clinical effects of four kinds of gingival retraction technique in treat-ment of anterior teeth restoration.Methods 169 patients for 352 teeth with tooth body and tooth dentition defect by anterior crown bridge repair were chosen and divided into 4 group by patients'order,including A group(88cases)with single track method,B group(91cases)with single line for two times method,C group(89cases)with double line method and D group(94cases)with double line for two times method.And the fixed restoration satisfaction rate of anterior teeth of both groups was compared.Results The satisfaction rates of gums,shoulder,impression,model and restoration of A group were 73.9%,70.1%,69.3%,65.9%,61.4% respectively,which of B group were 83.5%, 80.2%,80.2%,80.2%,76.9%;which of C group were 84.3%,80.9%,78.7%,77.5%,76.4%;which of D group were 94.6%,93.6%,92.6%,92.6%,90.4%.There were no significant differences in the fixed restoration satisfaction rate of anterior teeth between B group and C group(χ2 =2.43,1.17,2.85,3.04,2.30,all P >0.05). The fixed restoration satisfaction rate of anterior teeth of D group were significantly better than A,B and C groups (χ2 =14.90,16.39,15.83,19.87,21.38,all P <0.05 ).Conclusion Double line for two times method in the treatment of anterior teeth restoration can efficiently avoid ree gingival damage in the situation with abutment shoulder preparation,improve the quality of preparation,impression and model,and are helpful to higher the fitness of the neck of anterior teeth fixed restorations.

Objective To evaluate the value and safety of flexible bronchoscopy in etiological diagnosis and treatment of hemoptysis in children. Methods The flexible bronchoscopy findings and clinical data of 22 children with hemoptysis were ana-lyzed retrospectively. Results The causes of hemoptysis were as follows, bronchiolitis and pneumonia in 8 cases (2 cases with bronchiectasis), foreign body in bronchus in 3 cases , idiopathic pulmonary hemosiderosis in 3 cases, neoplasms in airway in 2 cases, suspi-ciion of bronchial pulmonary vessel dysplasia in 4 cases (requiring angiogram) and unknown causes in 2 cases. Two cases suffered hypoxemia. Active bleeding was found in 6 cases and topical hemostasis treatment was effective. The bronchial foreign body was removed from right lower lobe bronchus in 3 cases. One case with atelectasis caused by granulation was treat-ed with bronchoscopic cryotherapy 2 times, no granulation was found during the third bronchoscopy and chest CT showed the atelectasis was cured 2 weeks later. Conclusions Flexible bronchoscopy is one of the necessary and safe examinations in chil-dren with hemoptysis and is of important value in clinical diagnosis and treatment.

Objective To study early diagnosis and treatment of post transplant lymphoprolifer- ative disorder in allogeneic hemopoietic stem cell transplant recipients.Methods A 16 years old patient with severe aplastic anemia received HLA-mismatched sibling allogeneic hemopoietic stem cell trans- plant after conditioning with cyclophosphamide/antithymocyte globulin/methylprednisolone(CY/ ATG/MP)regimen.Results On the day 72 posttransplantation,he developed lymphoproliferative disorder.After withdrawal of CsA,he was treated with methylprednisolone,intravenous immune globulin and IFN alpha,and recovered completely from PTLD.Conclusions PTLD is a rare and fatal complication of both solid-organ and hemopoietic stem cell transplantation.Surveillance for PTLD by PCR for circulating EBV-DNA may be appropriate in high risk settings.Early diagnosis,immunosup- pression therapy reduction or even withdrawal in time is important.
