OBJECTIVE: To investigate the clinical value of sentinel lymph node (SLN) detection in laryngeal and hypopharyngeal carcinoma patients with clinically negative neck (cN0) by methylene blue method, radiolabeled tracer method and combination of these two methods. METHOD: Thirty-three patients with cN0 laryngeal carcinoma and six patients with cN0 hypopharyngeal carcinoma underwent SLN detection using both of methylene blue and radiolabeled tracer method. All these patients were accepted received the injection of radioactive isotope 99 Tc(m)-sulfur colloid (SC) and methylene blue into the carcinoma before surgery, then all these patients underwent intraopertive lymphatic mapping with a handheld gamma-detecting probe and blue-dyed SLN. After the mapping of SLN, selected neck dissections and tumor resections were peformed. The results of SLN detection by radiolabeled tracer, dye and combination of both methods were compared. RESULT: The detection rate of SLN by radiolabeled tracer, methylene blue and combined method were 89.7%, 79.5%, 92.3% respectively. The number of detected SLN was significantly different between radiolabeled tracer method and combined method, and also between methylene blue method and combined method. The detection rate of methylene blue and radiolabeled tracer method were significantly different from combined method (P < 0.05). Nine patients were found to have lymph node metastasis by final pathological examination. The accuracy and negative rate of SLN detection of the combined method were 97.2% and 11.1%. CONCLUSION The combined method using radiolabeled tracer and methylene blue can improve the detection rate and accuracy of sentinel lymph node detection. Furthermore, sentinel lymph node detection can accurately represent the cervical lymph node status in cN0 laryngeal and hypopharyngeal carcinoma.

OBJECTIVETo explore the changes of blood viscosity and external thrombus in patients with silicosis and silicosis complicated with tuberculosis (TB).

METHODBlood viscosity and external thrombus were measured in 288 patients with silicosis, 178 patients with silicosis complicated by TB and 150 healthy subjects.

RESULTSBlood viscosity and external thrombus value were significantly higher in the patients of silicosis and silicosis complicated with TB than in the healthy controls, except for patients of phase I of silicosis. Blood viscosity in the silicotics increased significantly with the advance of the disease, but no significant difference in external thrombus between patients in different phases. Apparent viscosity of whole blood significantly increased in the high-shear rate (200 s(-1)) and middle-shear rate (30 s(-1)) in patients of silicosis complicated with TB than in those without complication of TB at the same phases, but not seen in the low-shear rate (5 s(-1)) and in plasma viscosity, and the length and dried weight of external thrombus increased significantly too. There was no significant difference in blood viscosity and external thrombus between patients of silicosis at phase III and those of silicosis complicated with TB at the same phase.

CONCLUSIONBlood in patients with silicosis appeared highly viscous and highly coagulant status. Blood viscosity and external thrombus value significantly increased with the advance of the disease, especially in the patients complicated with TB.

AIM:To observe the alterations in cognition of growing rats exposed to chronic intermittent hypoxia (CIH) and to explore its underlying mechanisms. METHODS:Forty male Sprague-Dawley rats (3-week-old～4-week-old and 80 g to 100 g),which had been trained to complete the 8-arm (4-arm baited) radial maze,were randomly divided into 4 groups:2-weeek-CIH group (2IH),4-week-CIH group (4IH),-week -control group (2C) and 4-weeek-control group (4C). The intermittent hypoxia model was induced by putting the animals in an intermittent hypoxia cabin. When intermittent hypoxia was terminated,spatial memory of these growing rats was tested by 8-arm (4-arm baited) radial maze task,then,one rat in each group was randomly selected for ultrastructural observation. The hippocampus and prefrontal cortexes of the rats were collected for analyzing the mRNA and protein expression of CREB by RT-PCR and Western blotting,respectively. RESULTS:(1) In the 8-arm (4-arm baited) radial maze task,the results indicated that the rats in the 4 groups displayed significant difference in their performance assessed by three measuremens:the reference memory error,the working memory error and total memory error (P 0. 05,respectively). CONCLUSION:Exposure to experimentally-induced IH in growing rats is associated with time related spatial memory impairment. Chronic intermittent hypoxia leads to the disorders of neuron ultra-structure in memory related brain regions. It also inhabits the CREB transduction,expression and CREB phosphorylation,decreases the synthesis of the memory related protein. These factors maybe contribute to learningmemory impairment of growing rats exposed to chronic intermittent hypoxia.
