Objective To study the feasibility of contrast-enhanced ultrasonography (CEUS) in detecting sentinel lymph node(SLN) in patients with colorectal cancer during operation and their clinical significance.Methods Twenty-one patients who underwent radical resection of a primary colorectal cancer were enrolled.During operation,1 ％ methylene blue was injected around the tumor,SLN mapping was performed.Then the SonoVue was injected at the same sites,CEUS was performed to observe changes of SLN in real time,and marked them.The SLN detection rate and accuracy of CEUS were compared to those of conventional dye guided method.Results The rectal cancer of below peritoneal reflex,the detection rate of CEUS for SLN was 92.31 ％,and the accuracy was 88.89％.The detection rate of dye guided method for SLN was 84.62％,and the accuracy was 93.10％,there was no statistically significant difference between CEUS and dye guided method (P ＞0.05).Conclusions When injected SonoVue in submucosal layer,the good mapping of SLN of patients with rectal cancer of below peritoneal reflex can be obtained,it will play an important role in clinical application to map SLN of patients with rectal cancer of below peritoneal reflex.

Objective To study the change of the eonnxin43 expression in the heart of diabetic mellitus rats. Methods STZ-in-dueed diabetic mellitus in rats were developed. The expression of connexin43 in the heart was detected by immunohistochemistry and image analysis, and the heart function was observed by electrophysiolograph and echocardiogram. Results During the course of diabetic mellitus, the expression of connexin43 in the heart of diabetic rats decreased respectively in the 12th week and 24th week (P<0.01). The values of dp/dtmax and + dp/dtmax in group DM in the 12th week and 24th week were lower than that in normal control group respectively (P<0.01), and the LVEF were also decreased (12w P<0.05,24w P<0.01). The analysis of correlation showed that the expression of con-nexin43 in heart were positively correlated with heart function (P<0.05) . Conclusion The expression of Connexin43 evidently de-creased in the hearts of diabetic rats and it is positively correlated with the heart function.

Objective To investigate the application of get-well treatments in the suffers after thorax opera- tion over 70 years old. Methods 68 suffers after thorax operation over 70 years old were divided to two groups. Comparison group( n = 32 ) is actualized general nurse. Experiment group( n = 36) is actualized lung function exercise before operation, and get-well treatments after operation, such as psychologic get-well, deep breath, abdominal breath, effective cough and sputuming, applying apparatus training breath; exercise limbs and body, atomization in- breath, and so on. Results The suffers in experiment group who have lung atrophy,lung infection, liquid in the tho- rax,the time in the hospital and the time holding thorax pipe are less than the suffers in comparison group. Conclu- sion Lung function exercise before operation and effective get-well treatments after operation have significant ef- fects on old suffers.

Many factors can result in X ray film overthick and overthin in medical X-ray radiation.In order to ensure the correctness of diagnosis and the focus can be presented at the proper time,it is very im- portant for the overthick and overthin film to be processed and corrected.It has been proved through the test that the satisfied result can be reached through the proper regulating measure such as making a copy of a film.

Objective To evaluate diagnostic value of 3D time-of-flight (3D-TOF) magnetic resonance imaging (MRA) and postprocessing techniques in neurovascular compression (NVC) in trigeminal neuralgia.Methods 38 patients with trigeminal neuralgia were examined by 3D-TOF MRA.MRA fundament images and multiplanar reconstruction (MPR) images were blindly interpreted by 2 neuroradiologists.Results (1) Of all the patients, 31 cases showed vascular compression or contact on MR imaging, 26 cases showed the vascular compression or contact at the same side of clinic symptoms. There was a statistic correlation between NVC and trigeminal neuralgia ( P

Type I allergic reaction is the most common and serious one in the adverse drug reactions (ADR) of TCM injections. Skin test can be used to predict the occurrence of allergic reactions, which is a simple and effective method for safe use of TCM injections. To a certain extent, it can reduce ADR of medicine and ensure the safety of clinical medication. However, the medicine instructions of TCM injections that clearly point out the need for skin test are few, and there are many problems of skin test in clinical practice. For example, lack of systematic research on skin test, no uniform standard for clinical judgment, lack of diagnostic reagents and proprietary methods of skin test. Therefore, specifications for clinical skin test of TCM injections are needed to provide guarantee for the safe use of TCM injections.
