Objective To evaluate the advantage and clinical value of javanica oil emulsion injection combined with radiotherapy for esophageal carcinoma. Method Randomized controlled trials (RCTs) concerning javanica oil emulsion injection combined with radiotherapy for esophageal carcinoma were made on electronic databases of CBM, CNKI, Wangfang, VIP and PubMed from 1990 to February 28, 2015. Quality of the included RCTs was assessed by Jadad scoring , and Meta-analyses were performed by RevMan5.3 software. Results Seven RCTs involving 575 patients were included in Meta-analysis. All studies were in low quality. The results of Meta-analyses showed that Javanica oil emulsion injection combined with radiotherapy for esophageal carcinoma, compared with control groups, could increase the recent curative effect (P < 0.000 01) and improve the quality of live (P = 0.000 8), decrease the hematologic toxicities (P = 0.03) and the incidence rate of radioaction esophagitis (P = 0.02), but not enough evidence was found to prove that it can enhance survival rate (P = 0.25). Conclusions The results of Meta-analysis indicate that javanica oil emulsion injection may have therapeutic effects on the treatment of esophageal carcinoma. Yet the effects of javanica oil emulsion injection still need to be confirmed by large multi-center randomized controlled trials.

BACKGROUND: Sonography is believed by many scholars to be sensitive for the detection of hepatic arterial thrombosis and stenosis, but it is difficult to show the anastomotic vascular stenosis. MR angiography is better than sonography in the display of vascular anatomy and the diagnosis of various vascular complications after liver transplantation.OBJECTIVE: To evaluate the role of MR angiography (MRA) in the display of vascular anatomy and the diagnosis of various vascular complications after liver transplantation.DESIGN: Contrast trial observation.SETTING: Medical Imaging Center of Nanfang Hospital, Southern Medical University.PARTICIPANTS: Eleven adult male patients had undergone liver transplantations at Nanfang Hospital of Southern Medical University between January 2004 and December 2006. They ranged in age from 40 to 58 years, average 49 yeas. Original causes of liver failure in the study group included cirrhosis (n =9) and primal hepatic carcinoma (n =2) diagnosed by pathohistological methods. And 9 cases had undergone orthotopic liver transplantations while 2 cases with piggy-back liver transplantation.METHODS: Eleven consecutive adult patients underwent MR imaging examinations after orthotopic liver transplantation using a breath-hold 2D True Fast Imaging with Stead-state Precession and Fast Low Angle Shot. MR triphasic contrast-enhanced 3D imaging was also performed. Enhancement scan: A final gadolinium-enhanced axial and coronal T1WI spin-echo sequence with spectral fat saturation was performed after completion of the MRA. The vascular diameter stenosis was calculated according to S (S=[(D-d)/D]×100%) by ECST method, d as the inner diameter of the most obvious stenosis while D as normal diameter. Degree of stenosis: normal as S 0-30%, mild stenosis as S 31%-50%, moderate stenosis as S 51%-85%, and severe stenosis as S 86%-100%. Then the imaging findings after liver transplantation were analyzed. Meanwhile the sonography was performed.MAIN OUTCOME MEASURES: ① MR Image analysis of vascular anatomy and vascular complications after liver transplantation.②Normal findings after liver transplantation by using sonography.RESULTS: All 11 patients were involved in the result analysis.①MRA: The anastomosis of hepatic artery, portal vein and inferior vena cava were smooth in 3 cases. The high signal intensity was seen around portal vein at T2WI in 1 case with a shorter interval after transplantation and persisted 3 weeks. In 1 case, the caliber of the donor portion was smaller than the recipient portion. Among other 8 cases, hepatic artery complication included hepatic artery winding in 2 cases and aneurysm formation of donor's hepatic artery in 2 cases, but the twig of the hepatic artery was normal. Mild Portal vein stenosis at the anastomosis was found in 2 cases, caused by the different calibers of the donor portion from the recipient portion, but the inter-hepatic branches of the portal vein were normal. Clubbed dilatation of hepatic veins end-brush was depicted in 2 cases whose inferior vena cava at the anastomosis was not stenosis. Inferior vena cava thrombosis was found in 1 case. The thrombus displayed the low signal intensity in the high signal intensity of inferior vena cava. By follow-up examination, the degree of clubbed dilatation of hepatic veins end-brush reduced after half a year and inferior vena cava thrombosis disappeared by treatment. ②Sonography: By ultrasound examination, 1 case who had hepatic artery winding combining to aneurysm formation of donor's hepatic artery was discovered just hepatic artery winding. In 2cases that had mild portal vein stenosis at the anastomosis, 1 case was diagnosed normal while the other was not affirmed. The clubbed dilatation of hepatic veins end-brush was not depicted. The others were same as MRI diagnosis.CONCLUSION: Dynamic enhanced 3D MRA imaging can provide a comprehensive assessment of vascular anatomy in most recipients of liver transplants, and is an accurate and quick method to diagnose the vascular complication after liver transplantation.

Chronic obstructive pulmonary disease (COPD) is the leading death cause of pulmonary diseases, ranking the fourth of global death causes. Self-management program is able to gradually improve the Airways of COPD patients with ventilation, reduce the degree of lung failure, elevate the health status as well as promoting self-efficacy, which is the key process to effectively control COPD relapse. In recent years, more and more domestic and foreign academic employ the widely-used network technology and carry out a large number of information study on COPD self-management intervention. This article reviewed literatures about the intervention methods on self-management of patients suffered from COPD, aimed at providing a better basis for exploring more effective self-management.

Objective To investigate the relationship between the impairment of immunity and the level of NO in peripheral blood in patients with persistent vegetative state(PVS) resulting from severe brain trauma.Methods The levels of the cortisol and NO in peripheral blood of 12 PVS patients and the control group were tested respectively by radioimmunoassay and nitratase reducing colorimetic method.The phagocytosis and killing of Candida albicans by monocytes were observed.Results The NO content in peripheral blood of PVS group was dropped obviously,but the cortisol level was basically in normal range.Conclusion The suppression of immunity of PVS patients resulted from severe head trauma is related to the decreasing of the NO content in peripheral blood.

Objective To investigate the way of fear conditioning memory model evoked and erased by foot-shock in tree shrew. Methods First, detect the tree shrew activities regularly in light/dark box. Second, test a suitable voltage degree of foot shock on tree shrew. Third, investigate the memory formation and erasing of fear conditioning on tree shrew of trial group. Results The duration of tree shrew (n=4) stay in the dark-box was significantly lon-ger than that of in the light box (P<0. 01) in normal condition. In the same environment of two light boxes, given different voltage degrees, the durations of tree shrew (n=6) stay in the stimulating chamber gradually reduced and the durations of tree shrew stay had significant difference between stimulatus chamber and no stimulatus chamber when the stimulus voltage up to 12 V ( P<0. 05 ) , 16 V ( P<0. 01 ) and 20 V ( P<0. 01 ) . The animal of trial group ( n=4 ) could build up the fear conditioning memory of the dark box with the stimulus of 16 V foot-shock in the dark box ( P<0. 001 ) . After formation of the fear conditioning memory, the same stimulus in light box ap-peared for 4 days. The durations of tree shrew stay in trial group (n=4) decreased in light box, and there was no significant difference between the trial group and the control group. Conclusion Tree shrew prefers to stay in the dark box. The suitable voltage for foot-shock on tree shrew is 16 V. The fear conditioning memory can be evoked and erased by foot-shock.
