Objective To observe the protective effect of rhein-arginine (RhA) on rats ankylenteron and to explore the anti-inflammatory mechanism. Methods Sixty male SD rats were randomly divided into 6 groups:normal control group,model group,dexamethasone group (in the dose of 10 mg?kg-1) and low-,medium-and high-dose RhA groups (in the dose of 7.5 mg?kg-1,15 mg?kg-1,30 mg?kg-1 respectively). Except that the normal control group,the rats in other groups were induced ankylenteron. Intraperitoneal injection of saline was administered to the rats in the normal control group and the model group,and dexamethasone group and RhA groups were given the corresponding drugs according to the experimental design. The treatment lasted 7 days. On the 8th day after surgery the blood samples of each group were collected. The levels of interleukin-1?(IL-1?),interleukin-4(IL-4)and tumor necrosis factor-?(TNF-a)were determined by enzyme linked immunosorbent assay. Grades of ntestinal adhesion were ranked by macroscopic observation. The adhesive tissues between cecum and abdominal wall were taken for pathological observation and the determination of hydroxyproline (Hyp) content. Results RhA significantly relieved the experimental intestinal adhesion,Obviously decreased the levels of IL-1?and TNF-?,and inhibited the hyperplasia of fibrous connective tissue. However,there was no significant impact on the level of IL-4. Conclusion RhA can effectively prevent the information of postoperative ankylenteron by inhibiting the expression of inflammatory cytokines and reducing the inflammatory response.

Objective To study the appropriate neck irradiation volume for neck lymph nodenegative nasopharyngeal carcinoma patients by Meta-analysis.Methods The related references published from Jan 1990 to Jun 2013 were searched in Pubmed,Embase,Cochrane and Wangfang Databases.The qualified references for enrollment criteria were screened and the relative data were collected.The OR (Odds ratio) value by fixed effect model was used to evaluate the data for patients who received radiotherapy between the upper neck and whole neck irradiation.The endpoints including 5-year neck local control rate (LCR),neck-in-irradiation LCR,and neck-outsides-irradiation LCR.Results Five qualified references were screened and belonged to respective research.There enrolled 1 333 patients,including 970 patients who received the upper neck irradiation and 363 patients who received the whole neck irradiation,respectively.The forest plots revealed that there were no significant differences for 5-year neck LCR,neckin-irradiation LCR,and neck-outsides-irradiation LCR for patients received radiotherapy between the upper neck and whole neck irradiation.These OR values were 0.89 (95％ CI:0.41-1.94),1.29 (95％ CI:0.58-2.88) and 0.42 (95％ CI:0.07-2.36),respectively.Conclusions The Meta-analysis results suggest that irradiation to the upper neck for neck lymph node-negative nasopharyngeal carcinoma can be appropriate.

The means of survival of genomic dsRNA of reoviruses from dsRNA-triggered and Dicer-initiated RNAi pathway remains to be defined.The present study aimed to investigate the effect of Grass carp reovirus (GCRV) replication on the RNAi pathway of grass carp kidney cells (CIK).The dsRNA-triggered RNAi pathway was demonstrated unimpaired in CIK cells through RNAi assay.GCRV-specific siRNA was generated in CIK cells transfected with purified GCRV genomic dsRNA in Northern blot analysis; while in GCRV-infected CIK cells,no GCRV-specific siRNA could be detected.Infection and transfection experiments further indicated that replication of GCRV correlated with the increased transcription level of the Dicer gene and functional inhibition of in vitro synthesized egfp-siRNA in silencing the EGFP reporter gene.These data demonstrated that although only the genomic dsRNA of GCRV was sensitive to the cellular RNAi pathway,unidentified RNAi suppressor protein(s) might contribute to the survival of the viral genome and efficient viral replication.

Objective To evaluate the ultrasonic feature and clinical significance of persistent left superior vena cava(PLSVC)in fetal life.Methods Fetal echocardiography was performed in 3368 fetuses.Thirty-one fetuses of PLSVC were confirmed.Results The dilated coronary sinus was observed in 30 of 31 fetuses.Congenital heart defects were presented in 14 of these cases,and extracardiac anomalies were presented in 6 fetuses.Both congenital heart defects and extracardiac anomalies were observed in 4 fetuses.Conclusions PLSVC is always associated with congenital heart defects.The prognosis Of affected fetuses largely depends on whether or not the PLSVC is associated with a congenital heart defect.Prenatal diagnosis of PLSVC can help US plan perinatal counseling and ameliorate the postnatal course.

Objective To study the applicability of unilateral and bilateral antegrade cerebral perfusion during deep hy-potbermia circulatory arrest (DHCT) surgery and to determine a better method of brain protection. Methods 60 patients un-derwent aortic arch surgery were random divided into either unilateral cerebral perfusion group with a cannula in the innominate artery (n = 30 ) , or bilateral cerebral peffusion gToup with an additional cannula in the left carotid artery ( n = 30 ). S-100β,neuron specific enolase (NSE) were assayed at the following time points: the beginning of cardiopulmonary bypass (T_1), the beginning of circulatory arrcst( T_2 ), antegradc cerebral perfusion (ACP) 25 min( T_3 ), the end of ACP( T_4 ), the end of car-diopulmonary bypass ( T_5 ) , 1h( T_6 ) , 6h ( T_7 ) and 24h( T_8 ) after operation. Neurological deficit incidence and mortality were also obtained. Results There is no statistical significance for S-100β and NSE plasma concentration among time points of T_1、T_2 and T_3. But every time point among T_4、T_5、T_6、T_7 ,Ts do have statistical significances. The incidence of central nervous system dysfunction in group unilateral ACP was higher than that in group bilateral ACP ( 33.33% vs. 10.00%, P = 0.028 ).But there is no significant difference between the two groups in mortality( 3.33% vs. 6.66% ,P = 1. 000 ). Conclusion There is no significant difference between unilateral ACP and bilateral ACP in 25 min during DHCA. But as the DHCA time extends, the effect of bilateral ACP will be better.

Objective To assess the reproducibility of vascularization measurement in cervical carcinoma using transvaginal three-dimensional power Doppler angiography (3D-PDA) with virtualorgan computer-aided analysis ( VOCAL), and compare the reproducibility of two different contour mode (manual and automatic mode) of VOCAL. Methods Eighty patients with cervical carcinoma were examined by observer 1 using transvaginal 3D-PDA. The two acquired volume datasets were analyzed using manual and sphere automatic contour mode of the VOCAL imaging program for assessing carcinoma vascularization index( VI), flow index(FI), and vascularization flow index(VFI). Forty patients of them were examined randomly by observer 2 by the same method. Reproducibility of vascularity measurement was assessed by calculating intraclass (intra-CC) and interclass (inter-CC) , limits of agreement, 95% confidence interval definition. The contribution of various factors (examiner, measurement, contour mode and patient) to intrasubject variance was estimated using different analysis of variance models (ANOVA). Results For intraobserver,manual contour mode was more valid than sphere automatic contour mode for each observer (0. 92～0. 99 vs 0. 75～0. 94) ,and it also had smaller standard deviation,narrower limit of agreement range, 95% confidence interval and higher intra-cc than those of sphere automatic contour mode. Interobserver agreement of manual contour vascular measurements was similar to the intraobserver agreement for manual contour vascular measurements ( 0. 89 ～ 0. 97 vs 0. 92 ～ 0. 99 ) , but interobserver agreement for sphere automatic contour vascular measurements dramatically reduced (0. 52～0. 72). Conclusions Manual contour mode for 3D-PDA vascular measurement has better reproduciblity than sphere automatic contour mode, especially useful for irregular shape tissue.

Objective To investigate the clinical effect of lung equivalent uniform dose (LEUD)-based predictive model for radiation pneumonitis (RP) induced by volumetric modulated arc therapy (VMAT) and to determine the optimal a value.Methods A total of 65 patients with primary lung cancer who received VMAT from July 2015 to February 2016 were divided into RP group and non-RP group according to the presence or absence of RP after radiotherapy.Their dose-volume histogram (DVH) data and other data were obtained and analyzed by the self-compiled numerical analysis program.The LEUD values in the two groups were calculated at a=[-50, 50], and then the a value was identified when the relative difference of LEUD between the two groups was maximal.The paired t test was used for analyzing the differences in V5, V20, V30, minimum lethal dose (MLD), and LEUD (aoptimal) between the two groups.A Pearson correlation analysis was used to determine the correlation of Vdose and LEUD (aoptimal) with RP.The logistic regression method was used to establish the predictive model of RP.Results The maximum relative difference in LEUD between RP group and non-RP group was obtained at a=0.3(627.94 cGy vs.510.23 cGy, relative difference[R]=23.07%).R decreased slowly at t=[-50,-5], increased sharply at t=[-5, 0], and reached the maximum value at a=0.3.After a rapid decrease at a=[0.3, 4], R decreased slowly at a=[4, 50].The correlation analysis of the traditional physical volume dose threshold also showed that the LEUD (at a=0.3) was correlated with V5, V10, V20, and MLD (r=0.929, P<0.05).Conclusions For patients receiving VMAT for thoracic cancer, LEUD (at a=0.3) can distinguish between patients with and without RP.Therefore, LEUD is recommended to be<510 cGy.A combination of LEUD and conventional physical dose has a good clinical predictive value for RP under non-uniform irradiation.
