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.

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 evaluate the applied value of bedside chest radiography in the intensive care unit ( ICU ) . Methods One hundred and ninety-three cases with 507 chest radiographs (CXRs) in the ICU were analysed retrospectively. The appearances of cardiopulmonary abnormalities were analysed.Results 97.4% of the CXRs were satisfied for diagnosis. 83.9% of the CXRs showed cardiopulmonary abnormalities, including atelectasis, pneumonia, pulmonary edema, ARDS, pneumothorax, mediastinal and subcataneous emphysema,pleural effusion,pericardial effusion and pulmonary thromboembolism, and 6.2% out of these positive cases was discovered accidentally. The chest radiograph has moderate accuracy (77.9%) in visualizing cardiopulmonary abnormalities at the initial CXR including atelectasis,pneumonia,pulmonary edema and pleural effusion. Misdiagnosis occurred mainly on the patients with a small quantity of pneumothorax and pulmonary thromboembolism. About one-third cases of cardiogenic edema and ARDS were indistinguishable.Conclusion Bedside chest radiographs are of significant value for the patients in the ICU.

Objective To assess the contribution of the portable chest computed radiography (CR) in evaluation of monitoring devices of the patients in the intensive care unit (ICU). Methods One hundred and sixty-two cases with 387 chest radiographs in the ICU were analysed retrospectively. The location of the catheters of monitoring devices and complications were observed.Results The malposition of the catheters was detected in 47 cases(16.9%),including the endotracheal (ET) tubes too deep at the position, the central venous catheters placed into the internal jugular veins,and the position of the thoracic drain tubes to be deep not enough causing the drain to fall.The complications after operation of monitoring devices were not common,including pneumothorax caused by ventilatory assistance,atelectasis and pneumonia caused by malposition of the ET tubes,totally in 11 cases.10 cases with cardiopulmonary abnormalities were discovered accidentally in all 162 cases(6.2%) when evaluation of monitoring devices.Conclusion Bedside chest CR not only can show the catheter position and the complications of the monitoring devices ,but also the cardiopulmonary abnormalities of patients in the ICU.
