Objective To discuss the characteristics of ultrasonic images obtained by color Doppler per rectum after intrarectal pouring and the advantages of this method.Methods 40 cases who were diagnosed as rectal carcinoma prior to surgeries were investigated.The rectum was cleand and then was poured with normal saline before examination.Color Doppler ultrasonography per rectum was performed with intrarectal probe touching the inferior edge of the tumor.The 2-dimensional images and color Doppler images were then analyzed.Results The accurate typing of rectal tumors(detailedly,the ulcerative,intumescent,and confined types)can be obtained with this method.Within the 40 cases,24 were ulcerative,12 were intumescent and 4 were confined.Only one case with ulcerative tumor was misdiagnosed as intumescent.The total accuracy rate was 97.5%.As with rectal tumors less than 5cm,there was no significant difference between the measurement by ultrasonography and that by pathologic methods (P＞0.05).While for tumors larger than 5cm,the measurement by ultrasonography was significantly different from that by pathologic methods (P＜0.05).There was no significant correlation between the bloodstream signal of color Doppler and pathological grading(P＞0.05).The method can be applied for patients who have a narrow rectal duct or are suffering from agonies which prevent the passage of the colonoscope.For cases failing to detect the margin and surface of the tumor with routine method,or ultrasonic probe failing to pass the confined area leading to illegible 2-dimensional images,This method is competent as well.Conclusion Color Doppler ultrasonography per rectum after intrareetal pouring can be applied for the diagnosis of rectal tumors of all types.

Objective To investigate the effects of nitric oxide (NO) inhalation on the expression of TNF-?,IL-8 and CD11b mRNA in lung tissue during acute respiratory distress syndrome (ARDS) induced by intravenous injection of endotoxin in dogs.Methods Twelve pure bred beagle dogs of both sexs weighing 8-12.5 kg were randomly divided into 2 groups: NO group received mechanical ventilation with NO inhalation (n = 6) and control group received only mechanical ventilation ( n = 6) . Sepsis and ARDS were induced by intravenous injection of endotoxin as described in detail in our previous paper. Hemodynamics and pulmonary oxygenation were monitored and shunt fraction was calculated. At the end of experiment the animals were sacrificed and lung tissue was obtained aseptically and stored in the liquid nitrogen at - 180℃ . The total RNA was extracted. Reverse transcription-polymerase chain reaction (RT-PCR) was used to detect the expression of TNF-?,IL-8 and CD11b mRNA. The total RNA was reversely transcripted to cDNA. Then the cDNA was amplified by PCR. The product of PCR was scanned by gel-image analysis system.?-action was used as internal control. Semi-quantitative method was adopted for measurement of TNF-? ,IL-8 and CD11b mRNA expression. Results The expression of TNF-?, IL-8 and CD11b mRNA in lung tissue was significantly decreased in NO group compared with those in control group.Conclusion NO inhalation reduces expression of TNF-?, IL-8 and CDllb mRNA in lung tissue during ARDS induced by intravenous endotoxin.

CG. And that was why SSP failed to determine the allele.Conclusion The difficulty in HLA genotyping by SSP resulted from the primers, which involved unknown sequence of Exon 1 at locus B in the studied sample.

OBJECTIVE To reduce the missing report rate of nosocomial infection(NI) by establishing relevant surveillance protocol,improve the early warming system of NI,and therefore prevent the outbreak and prevalence of NI.METHODS Based on Nosocomial Infection Diagnosis Standard published by Chinese Ministry of Health in 2001,116 213 patient data from Jan 2000 to Dec 2006 had been reviewed;factors associated with NI missing report rate had been reevaluated;measures to reduce the rate had been made;and the feedback information of NI control had been collected.Meanwhile,according to high risk factors provided by the hospital information system,the prospective investigations had been made.Surveillance protocol had been established as above.RESULTS By the implementation of the protocol,the missing report rate of NI had been under control,lower than the standard rate of 20% for tertiary hospitals.In 2005,the protocol was reinforced and the NI missing report rate had been reduced to 7.4% by 2006.CONCLUSIONS The real-time monitoring of NI cases is an effective way in reducing missing report rate of NI.

Wheezing is the most common respiratory disease in children.In recent years,the incidence of childhood wheezing showed an upward trend,the hot topic in the current study is how to draw up a rational and effective treatment to reduce wheezing.This paper summarized the latest research progress of pathogenic factors,clinical classifi-cation,pathogenesis and prevention strategies in childhood wheezing.It aimed to provide a theoretical basis for early diagnosis and individual treatment for children with wheezing diseases.

Objective To evaluate the clinical value of color Doppler ultrasound-guided percutaneous transhepatic cholangiol drainage(PTCD) for treating obstructive jaundice. Methods 248 cases of PTCD were performed in 224 patients under the guidance of color Doppler ultrasound. 118 PTCD cases were carried out passing through the inferior segmental biliary duet of Left laterallobe (Left drainage mode). Right lobe drainage mode (right drainage mode)was conducted in 130 patients. Left plus right lobe drainage mode in 16 patients. Results The total success rate was 99.59 %(247/248), and the success rate of the firs time PTCD was 92.33 %(229/248). The success rate of left drainage mode was significantly higher than righl lobe drainage (96.61% vs 88.46 %, P ＜0.05). Conclusion The technique of color Doppler ultrasound-guided PTCD is an efficient method in obstructive jaundice therapy, with the advantages of safety, convenience, minimal invasion, and higher success rate.

The patent information of ultrasound countercurrent extraction used in traditional Chinese medicine was analyzed in this paper by the samples from Derwent World Patent Database (DWPI) and the Chinese Patent Abstracts Database (CNABS). The application of ultrasound countercurrent was discussed with the patent applicant,the amount of the annual distribution, and the pharmaceutical raw materials and other aspects. While the technical parameters published in the patent was deeply analyzed, such as material crushing, extraction solvent, extraction time and temperature, extraction equipment and ultrasonic frequency. Thought above research, various technical parameters of ultrasound countercurrent extraction used in traditional Chinese was summarize. The analysis conclusion of the paper can be used in discovering the technical advantages, optimizing extraction conditions, and providing a reference to extraction technological innovation of traditional Chinese medicine.
