Isolated superior mesenteric artery dissection (ISMAD) is a clinically common disease,of which multi-slice spiral computed tomography (MSCT) is effective method for screening and follow-up.The diagnosis and treatment should be made based on pathological changes of true or and false lumen.Most patients can relieve by medical treatment,and those with treatment failure can adapt endovascular treatment.Patients with aneurysm rupture or intestinal necrosis should undergo emergent surgical treatment.

Objective: This item presents a feasible scheme of home monitoring device which is a low power and miniaturization equipment for human signal detection, based on single-chip technology. Methods: Taking MSP430F149 as core, the realized functions of system contain real time data acquisition, data processing, data storage, LCD and alarming, keyboard as well as com-munication, replay and reproeessing by host computer. Results: The physiological and biochemical parameters are acquired by system and transmitted to host computer. Conclusions: This design provides a platform for multi-parameters portable detection just as dynamic ecg, ambulatory blood pressure, and so on. It has a good future for application.

Tumor lysis syndrome (TLS) results from a sudden and rapid release of nuclear and cytoplasmic degradation products from malignant cells. It is a rare complication in adult patients with solid tumors who are undergoing treatment. Herein, the authors present a case with advanced hepatocellular carcinoma (HCC) who developed TLS after transarterial chemoembolization (TACE), which was successfully treated with aggressive fluid administration, oral allopurinol and urine alkalization, hemodialysis and other supportive therapies. TLS following TACE should be suspected in HCC patients who has large and rapidly-growing lesion.

Objective To observe the effects of mild hypothermia on the dynamic change of neuron specific enolase (NES) in serum, the damaged neuron number around the impact site and the content of brain tissue water following traumatic brain injury (TBI) in rats so as to provide a quantitative parameters to evaluate the protective effect of the mild hypothermia on the brain. Methods A total of 45 SD rats were subjected to a lateral moderate cortical impact injury caused by a free-falling object and divided randomly into three groups:⑴ sham operation group (Group A);⑵ normothermic group (Group B);⑶ hypothermia group (Group C). The Group C was treated with mild hypothermia and the Group B with normothermia immediately after injury. A series of samples were obtained directly 3, 6 and 24 respectively after trauma in three groups. Pathomorphological method was used to observe the number of the damaged cortical neurons around the impact site. The serum concentration of NSE and the water content of brain tissue water were measured by radio-immunoassay. Results Following TBI in rats, the serum level of NSE was significantly increased (P

Objective:To study the a feasibility of modified pharyngoplasty in the treatment of velopharyngeal insufficiency.Methods:30 cases of velopharyngeal insufficiency were treated with a modified pharyngoplasty followed by speech training.The effects of the treatment were evaluated by blowing test (BT),chinese articulation inteligibility test (CIT) and hypernasality observation(HO).Results:Before and after treatment BT was 1～26 and 8～40,CIT(%) 20～60 and 47～82,HO(cases) 30 and 3,respectively.Conclusions:The modified pharyngoplastic surgery is feasible in the treatment of velophayngeal insufficiency.

Objective:To apply electropalatography(EPG) in speech training for the patients with misarticulations caused by abnormal palatolingual contact, such as palatalized misarticulation(PM) and lateral misarticulation(LM) because of cleft lip and palate. Methods: Four patients with cleft lip and palate averagely aged 12.5 years old were enrolled in this study. PM was found in all the patients with or without LM. Misarticulations of these patients were corrected by visual feedback of EPG in speech training. Speech intelligibility and electropalatogram before and after therapy were compared. Results: It was convenient for the patients to check their pronaciation by the visual feedback of EPG.Their speech intelligibility was improved and palatolingual contact were more anterior after speech training. Conclusion: EPG is a valuable instrument in speech training for patients with misarticulation

Objective To investigate the efficacy of gelatin sponge particles(GSP)or polyvinyl alcohol particles (PVA) for hemoptysis secondary to bronchiectasis or pulmonary tuberculosis. Methods The clinical data on 271 patients with bronchiectasis- or tuberculosis-induced hemoptysis were retrospectively analyzed. The efficacy and rates of recurrence and complications were analyzed. Results A total 271 patients were included in this study, 176 of whom suffered from bronchiectasis and the rest 95 had tuberculosis. One-week cure rate was signifi-cantly higher in bronchiectasis group than in tuberculosis group(73.3%vs. 46.3%,P<0.05),and one-year recur-rence rate was significantly lower in bronchiectasis group(17.6%vs. 26.3%,P<0.05). One-year recurrence rate was slightly higher in patients receiving GSP than in those undergoing PVA(bronchiectasis group:22.2%vs. 10.3%, P<0.05;tuberculosis group:28.8%vs. 22.2%,P>0.05). No severe complications occurred. Conclusions In-terventional artery embolization therapy for hemoptysis secondary to bronchiectasis is better than tuberculosis-induced hemoptysis,and PVA is more effective than GSP. Recurrence of massive hemoptysis mostly occurrs within one month ,and most of the patients are complicated with blood supply and have a history of hemoptysis.

Objective To investigate the therapeutic efficacy of transcatheter arterial embolization (TAE) in treating advanced bladder cancer. Methods A total of 22 patients with advanced bladder cancer were included in this study. The clinical data and the imaging materials were retrospectively analyzed. The clinical efficacy of TAE in treating advanced bladder cancer was evaluated. Results TAE was successfully accomplished in all the 22 patients. The preoperative and the postoperative abdominal pain scores were 4.73± 1.91 and 2.45±1.29 respectively, the difference was statistically significant (P<0.01); the preoperative and the postoperative ECOG scores were 3.14±0.47 and 2.68±0.56 respectively (P<0.05); the preoperative and the postoperative hemoglobin levels were (61.4±11.8) g/L and (79.3±14.5) g/L respectively (P<0.01). Of 7 patients with urinary tract obstruction, after the treatment the obstruction disappeared in 5 and was improved in 2, although the urination was still not smooth. All patients were followed up for (7.1±3.0) months. The 6-month survival rate was 54.5% (12/22). No serious complications occurred in all patients. Conclusion TAE can not only effectively improve the hematuria and urinary tract obstruction symptoms caused by bladder cancer, but also effectively control the tumor growth, improve the quality of life and prolong the survival time as well.

Usually the survival period of patients with duodenal obstruction caused by inoperable advanced pancreatic cancer is rather short. For such patients, minimally invasive treatment should be employed as the first choice. This paper reported a case with advanced pancreatic cancer complicated by biliary and duodenal obstruction. After implantation of biliary stent, the obstructive jaundice was relieved. Because of the insufficient cardiac function, the patient was not able to tolerate gastrojejuostomy; besides, as both DSA-guided stent implantation and endoscopic nutrition tube placement failed to success, implantation of nutrition tube via the trans-hepatic and biliary route, as a novel tube placement technique, had to be carried out, and the result in this case was satisfactory.
