Background and purpose: Metastatic carcinoma and lymphoma are usually the causes of cervical malignant lymph nodes. This paper was aimed to investigate the different appearances of cervical malignant lymph nodes by 2 dimension and color doppler flow imaging (CDFI) and discuss the role of ultrasenography in diagnosing cervical malignant lymph nodes. Methods: Ninety-nine patients and 40 healthy people were selected as our subjects, among which 54 cases were diagnased as metastatic tumor and 45 cases as lymphoma according to pathology examination. With high frequency transducers, ultrasonography was used to document the shape of cervical lymph nodes, the ratio of long/short axis (L/S), types of echo and hilus of lymph node. CDFI features were also recorded and measured in order to analyze the parameters. Results: Compared with image of normal lymph nodes, the image of cervical malignant lymph nodes showed that the shape tended to be round and the ratio of L/S decreased. In addition, the majority of echo types of malignant lymph nodes was a low level echo and easily became fused. Meanwhile, the image of hilus of lymph node tended to disappear or shift. The lymph node of cases with metastatic tumor was shown to be either calcified or liquefied. The rate of blood flow in the artery was observed to be of high velocity and high resistive index (RI). Between metastatic tumor and lymphoma tumor case, there was significant difference in terms of ultrasonographic and CDFI features. All the above results showed that the features of malignant lymph nodes were significantly different from the normal ones. Conclusion: Ultrasonography could be regarded as one method of evaluating cervical malignant lymph nodes.

BACKGROUND:In root canal preparation, the clearance effect of sodium hypochlorite for root canal irrigation on the smear layer is associated with the contact time and contact area of irrigation fluid, the amount of irrigation fluid, irrigation fluid temperature, irrigation fluid concentration, flushing methods and so on. OBJECTIVE:To investigate the clearance effect of 3% sodium hypochlorite on the smear layer of root canal under different flushing methods, flushing temperature and flushing time. METHODS:Totaly 180 isolated front teeth with single root were colected and root canal preparation was conducted using motorized ProTaper. The root canal was flushed with 3% sodium hypochlorite. According to different flushing methods, these root canals were randomly and evenly divided into root canal active flushing group, passive ultrasound swished group and side opening flushing needle group. According to the flushing temperature and the flushing time after replacing a file, each group was randomly divided into six subgroups: 20℃ 30 seconds group, 20℃ 60 seconds group, 37 ℃ 30 se group. The clearance effect on the smear layer of root canal was observed using scanning electron microscope. RESULTS AND CONCLUSION:The general clearance effect on the smear layer in the root canal active flushing group was better than that in the passive ultrasound swished group and side opening flush acupuncture group (P< 0.05). At the same time, the clearance effect on the smear layer in the 60℃ group was better that that in the 37 ℃ group and 20℃group (P < 0.05). At a certain temperature, the clearance effect on the smear layer in 60 seconds group was better than that in the 30 seconds group (P < 0.05). The clearance effect on the smear layer in the 1/3 root cap zone was better than that in the 1/3 root and 1/3 apical root zone (P < 0.05). These results show that the best clearance effect on the smear layer can be achieved as folows: 3% sodium hypochlorite irrigation at 60℃ for 60 seconds.
