Objective To evaluate the application of M2A capsule endoscopies ( CE) in the diagnosis of digestive tract diseases. Methods Forty - five patients (26 males, 19 females) , suffered from gastrointestinal bleeding, abdominal pain or chronic diarrhea were referred to this study and underwent capsule endoscopies. Their average age was 47. 8 years old (a range of 15 - 78). Capsule endoscopies were performed with the Given M2A video capsule system. The conventional diagnostic procedures (including small bowel radiograph, gastroenteroscopy, colonoscopy, etc. ) were done in 31 patients before or after the CE, thus the results of both procedures were compared. Results Among 45 patients, 44 have completed CE successfully. Any complication never experienced. The quality of photos was excellent. The significant pathological findings were revealed in 37 patients, diagnostic yield was therefore 84. 1% . Patients with esophagogastric diseases, small bowel diseases and colon diseases were found in 5,29 and 3 cases respectively. Thirty -one patients received a conventional diagnostic procedure before or after CE. Twenty one of them suffered from GI bleeding, pathological changes were found in 17 patients by capsule endoscopies, only 4 patients by conventional procedure; five of them suffered from abdominal pain, pathological changes were found in 5 patients by CE, only 2 patients by conventional procedure; 4 of them suffered from chronic diarrhea, pathological changes were found in 4 patients by CE, only 1 patient by conventional procedure. The pathological sites located by CE were quite similar to those by conventional diagnostic work-up. Conclusion CE has the advantages of high safety, excellent visualization and precise localization. Its efficiency in diagnosis is much better than that of conventional procedure, and is indispensable in the diagnosis of digestive tract diseases.

Objective To observe the effects of different doses of dexmedetomidine combined with ropiva-caine for ultrasound-guided fascia iliaca compartment block on postoperative analgesia and rehabilitation in patients undergoing total hip replacement surgery. Methods 80 patients with ASAⅠ~Ⅱundergoing total hip arthroplasty were ramdonly divided into 4 groups. Records of patients with ultrasound guided fascia iliaca compartment block onset time,block fading time,VAS at 4 h,8 h,12 h,24 h,48 h;duration of operation,intraoperative remifent-anil and propofol requirement;24 h and 48h of sufentanil use;after the operation were recorded for the first time , ambulation time,hospitalization time and observe whether bradycardia,intraoperative awareness and other adverse reactions. Results Compared with group A and B,the onset time of C were shorter(P<0.05);the VAS was less (P<0.05);the remifentanil equirement was significantly was reduced(P<0.05);the amount of sufentanil after operation 24 h and 48 h was reduced(P<0.05);the first time out of bed time and total hospitalization time was shorter(P < 0.05);patient satisfaction increased(P < 0.05);The extubation time was significantly longer and the occurrences of tachycardia were significantly increased in group D compared to other groups respectively. Conclusion 1.0μg/kg dexmedetomidine combined with 0.3%ropivacaine ultrasound-guided fascia iliaca compart-ment block can provide better postoperative analgesic and recover rapidly with fewer side effects in total hip replace-ment surgery.

Objective To observe the effect of 2,3,5,4'-tetrahydroxy stilbene-2-?-D-glycoside (TSG)on learning and memory and free radicals metabolism in mice with dementia induced by ?-amyloid(A?).Methods The mice models were established by injection of A?1-40 into the right lateral ventricle,and the treatment group was administered with TSG for 8 weeks by gastrogavage.Morris water maze and step-through test were performed in all the mice and then the mice were killed and radioimmunoassay was used to detect the content of interleukin-6(IL-6).Results The learning and memory in model mice were worse and the cortical IL-6 content increased compared to the normal control mice.TSG improved the learning and memory of A?-induced model mice and reduced cortical IL-6 content.Conclusion TSG could improve the learning and memory of dementia mice and decrease cortical IL-6 content,indicating a promising prospect in the treatment of dementia disease such as Alzheimer's disease.

ObjectiveTo observe the effect of 2,3,5,4'-tetrahydroxy stilbene-2-β-D-glycoside(TSG) on learning and memory ability and free radicals metabolism in dementia model mice induced by β-amyloid (Aβ).MethodsAβ1-40 was given to the right lateral ventricle in the model group, and the TSG had been administered to the therapy group for 8 weeks by gastrogavage.All the mice of different groups were tested with Morris water maze and step-through test. Then the mice were killed and biochemical assays of neurol MDA,MAO-B,T-AOC were performed.ResultsThe model mice showed worse ability in learning and memory compared with control mice. The MDA cotent, MAO-B activity in the cortical increased in model mice compared with normal control; TSG reduced the MDA content, MAO-B activity,and increased T-AOC activity.ConclusionTSG can improve the learning and memory ability of model mice, decrease peroxidation level of brain, and increase antioxidation ability of brain, which suggest that TSG may have a promising application in treatment of dementia disease such as AD.

Objective To study the clinical value of capsule endoscopy for small bowel diseases in pediatric and adolescent patients.Methods Clinical data of 61 pediatric and adolescent patients who underwent capsule endoscopy from February 2007 to April 2014 was respectively analyzed.The positive diagnostic results and safety were observed.Results Of 61 patients,the CE procedures were completed successfully in 58 patients,and failed in 3 patients because of the gastric stasis.Forty-one positive lesions were found in small intestine,and the detection rate was 70.69％.Positive findings included angiodysplasias,Crohn' s disease,Meckel diverticula,ulcer,P-J syndrome,protrusion lesion and enteritis,etc.Finally,29 patients were confirmed (50％),3 (5.17％) were misdiagnosed and 1 (1.72％) was missed.Twenty-two patients underwent other small bowel examinations besides the capsule endoscopy.And the accuracy of capsule endoscopy was 81.82％.All capsules were successfully swallowed by the patients and evacuated within two weeks.No complications such as capsule retention or intestinal obstruction occurred.Conclusion Capsule endoscopy is a safe and well tolerated procedure with high diagnostic rate,which has a prospective clinical value in small bowel diseases in pediatric and adolescent patients.

Background and purpose:Breast masses is woman's common diease,With the development of people's living.They are eager to find a new method which is efficient and less pain to replace conventional open surgery.So Mammotone appears.We assessed the efficacy of Mammotome biopsy system for the patients with single and multiple breast masses.We assessed the efficacy of Mammotome biopsy system for patients with single and multiple breast masses.Methods:From Janurary 2004 to April 2005,patients with single and multiple breast masses underwent Mammotome and conventional surgery respectively.Two methods has been compared from the aspects of difficulties,side effects,prognosis and degree of patient's satisfaction.Results:The length of excisions,anesthetic dosage,operational time,pain etc with Mammtome group were superior to the conventional group,especially for the patients with multiple breast masses.There were no difference in terms of bleeding during or after operation for two groups.Patients were followed up 3 to 15 months,none of the patients had relapse and patient's satisfaction was very encouraging.Conclusions:The color guided Mammotome showed very promising results for the patients with breast benign masses,and it was very useful for the masses either located deeply or were multiple.
