Objective: To evaluate the nutritional status of gastrointestinal carcinoma patients by mini-nutritional assessment(MNA),and to compare the relationship with different tranditional evaluative methods. Methods: The nutritional state and the malnutritional incidence were analysed by MNA questionnaire in 496 gastrointestinal carcinoma patients,and the relationship among MNA score and anthropometric measurements and laboratory test was studied.Results: ①According to the scores of MNA, 16.94%(84/496) patients were of mal-nutrition and 42.54%(211/496) patients were at risk of malnutrition.② In terms of each single index,BMI,TSF,AC and AMC,the prevalence of malnutrition was 13.5%,21.9%,15.1% and 15.5% respectively.③According to laboratory test,including serum albumin,PA,TLC,the incidence of malnutrition was 14.9%,25.4% and 30.8%.④ There was a significant correlation between the MNA score and tranditional nutritional estimated markers.The correlation coefficients of MNA with BMI,ALB,AC,TSF,AMC and TLC were between 0.18 and 0.53(P

ObjectiveTo explore the correlation of contrast-enhanced ultrasound (CEUS) parameters and the pathologic parameter of renal fibrosis.MethodsThirty-eight healthy New Zealand rabbits were randomly divided into the blank control group and the experimental group. The rabbits model was built by intravenous injection of C-bovine serum albumin (C-BSA) to rabbits of the experimental group. According to the different time points (2, 4, 6 and 8 weeks) after the injection of C-BSA, the rabbits in experimental group were randomly divided into 4 sub groups, 8 in each group. We collected the data of the CEUS parameters in the control group and the experimental group. Moreover, the renal tissues of the rabbits underwent pathologic examinations. Then, correlation analysis of CEUS parameters with parameters of renal fibrosis was performed.ResultsDynamic changes of CEUS parameters: Renal cortical perfusion reduced from 6 weeks after the injection, manifested as the time to peak (TTP) and mean transit time (MTT) of the experimental group were longer than those of control group and the derived peak intensity (DPI) of the experimental group was lower than that of control group (P<0.05 respectively). The DPI and TTP at 8 weeks after the injection of the experimental group was significantly lower than those of the control group [(26.96±2.34) dbvs (35.04±1.62) db,P<0.05; (24.31±1.82) svs (18.64±1.15) s,P<0.01]. Changes of each renal fibrosis parameter: we found that the results of the glomerulosclerosis indexes of the experimental group (4 weeks, 6 weeks and 8 weeks after the injection) were significantly higher than those of the control group (0.81±0.36, 1.43±0.25 and 2.15±0.30vs 0.13±0.07, allP<0.01). The tubular interstitial collagen deposition scores of the experimental group (4 weeks, 6 weeks and 8 weeks after the injection) were significantly higher than those of the control group (14.29%±4.62%, 26.28%±10.09% and 42.37%±10.41%vs 1.21%±0.15%, allP<0.01). As the disease progressed, the results of each parameter increased. Pearson correlation analysis showed that the TTP of renal cortex was positively correlated with the glomerulosclerosis index and tubular interstitial collagen deposition score (r=0.866 and 0.785, bothP<0.01). The DPI of renal cortex was negatively correlated with the glomerulosclerosis index and tubular interstitial collagen deposition score (r=-0.724 and -0.739, bothP<0.01).ConclusionsThe results showed that CEUS could evaluate microcirculation perfusion of renal cortex. There is a positive association between TTP and fibrosis index. There is a negative association between DPI and fibrosis index. Thus, CEUS is an important method to evaluate the renal fibrosis in chronic renal nephropathy.

Objective To investigate the characteristic and the value of renal solid lesions' boundary at contrast-enhanced ultrasonography(CEUS). Methods The study included 225 patients (124 males, 101 females) with renal 239 solid lesions [133 renal cell carcinoma(RCC) and 106 benign lesions]. The enhanced mode of lesion boundary at CEUS was observed. The histopathologic pseudocapsule of RCCs was analysed.Results Enhanced modes of all lesions' boundary at CEUS were classified as: type Ⅰ , iso-enhanced boundry in whole phase, 82.85 % (198 of 239) ;type Ⅱ , a perilesional annular highly-enhanced signal at early phase,4.18% (10 of 239);type Ⅲ ,perilesional annular highly-enhanced signal in whole phase,9.62% (23 of 239) ;type Ⅳ, perilesional annular highly-enhanced signal in midium and late phase, 1.25 % (3 of 239) ;type Ⅴ ,iso-enhanced boundry in the mdium and late phase with no enhancment at early phase, 2. 09% (5 of 239). The distribution of types Ⅰ , Ⅱ , Ⅲ between groups were significant different( P=0.000, 0.046,0. 000), the type Ⅳ and Ⅴ was not ( P = 0.256,0.068). The distribution of perilesional annular highlyenhanced signal between benign and RCC groups was statistically different (x2=29. 681, P=0.000).Regared it as a diagnostic criteria of RCC,the sensitivity was 26.32% (35/133) ,the specificity was 99.06%(105/106) ,the positive predictive value was 97.22% (35/36),the negative predictive value was 51.72%(105/203) ,and the accuracy was 58.58% (140/239). The perilesional annular highly-enhanced signal was not correlated with the pseudocapsule in pathology ( P = 1. 000). Conclusions The boundary enhancement mode of renal solid lesions at CEUS was divided into five types. The perilesional annular highly-enhanced signal was important in diagnosis of RCC,which was not correlated with the pseudocapsule in pathology.

Purpose Chronic nephropathy model was established with New Zealand rabbit, and the development of chronic nephropathy was monitored using virtual touch tissue quantification (VTQ) technique, to provide the experimental basis for chronic renal fibrosis assessment using VTQ technique. Materials and Methods Thirty-eight healthy New Zealand white rabbits were selected, of which 32 were induced into chronic nephropathy model with daily intravenous ear vein injection of cationic bovine serum albumin (C-BSA), with the other 6 rabbits without C-BSA injection as control group. At the end of 0, 2, 4, 6, 8 weeks, VTQ was used to measure the hardness of renal cortex in rabbits, then the rabbits were slaughtered to assess the pathological changes in kidney, correlation analysis between the VTQ parameters and the pathological parameters was performed. Results VTQ value of rabbit kidney cortex at 0 week, 2 weeks, 4 weeks, 6 weeks and 8 weeks was (1.68±0.25) m/s, (1.70±0.31) m/s, (1.87±0.35) m/s, (2.19±0.31) m/s and (2.46±0.46) m/s respectively, difference of VTQ values between 6 weeks and 4 weeks was statistically signiifcant (P<0.05), and also signiifcant when compared 8 weeks with 4 weeks and 6 weeks (P<0.05). Glomerulosclerosis index of 4 weeks, 6 weeks, 8 weeks were 0.81±0.40, 1.43±0.46 and 2.15±0.46 respectively, and tubular interstitial collagen deposition score were (14.29±4.62)%, (26.28±11.06)%, (42.37±10.09)%, which were all significantly higher than that in 0 week and 2 weeks, fibrosis increased gradually with the course, the difference was statistically signiifcant (P<0.05). Correlation analysis showed that the VTQ value of renal cortex was positively correlated with glomerulosclerosis index (r=0.663, P<0.05) and tubular interstitial collagen deposition score (r=0.652, P<0.05). Conclusion VTQ technique is able to detect the VTQ change of renal cortex as the disease progressed in rabbits with chronic renal nephropathy, which was in a positive association with fibrosis index, suggesting that virtual touch tissues quantitative technology can be an important method to evaluate renal ifbrosis in chronic renal nephropathy.

Objective: To investigate the influence of fast tract surgery on the humoral immunity and the chief clinical index of gastric cancer patients.Methods: 56 patients with gastric cancer from December 2007 to June 2008 were randomly divided into two groups: experiment group(fast tract surgery group, n=28)and control group(conventional treatment group, n=28 ). The changes of serum levels of humoral immunity and the chief clinical index were analysed and compared.Results: The serum levels of humoral immunity in both group were decreased. The serum levels of C3 and C4 on the postoperative 1st day were(0.845±0.126)g/L and(0.212±0.070)g/L respectively(P<0.05) in FTS group.The serum levels of IgA, IgM and IgG on the postoperative 3rd day were(1.603±0.468)g/L,(0.845±0.187)g/L,(9.548±1.920)g/L respectively(P<0.05) in FTS group. The duration of antibiotic use, first passage of flatus, the lengh of hospital stay, the occurance of postoperative complications in FTS group were also significiantly lower than those in control group (P<0.01, P<0.05).Conclusion: Fast tract surgery affectes on the humoral immunity of gasrtic cancer patients, and it might contribute to the improved outcomes of postoperative patients.

Objective To explore the effect of social support and coping style on posttraumatic growth of ostomy patients. Methods A total of 237 patients with ostomy from Affiliated Hospital of Qingdao University were investigated using General questionnaire, Perceived Social Support Scale, Medical Coping Modes Questionnaire and Posttraumatic Growth Inventory by cross-sectional survey method from September 2017 to March 2018. The path of social support and coping style on post-traumatic growth was established by correlation analysis and structural equation model. Results The total score of posttraumatic growth in patients with ostomy was (66.76±12.20) points, which was at the upper-middle level. Correlation analysis showed that posttraumatic growth was positively correlated with comprehension of social support (r=0.551, P<0.01), positively correlated with face style (r=0.580, P<0.01), negatively correlated with avoidance style and resignation style (r=-0.334, P<0.01;r=-0.449, P<0.01). Structural equation model showed social support had directly positive effect on posttraumatic growth, path coefficient were 0.44. Face style, avoidance style, and resignation style had a partial mediating effect between social support and posttraumatic growth, and mediation effects account for 20.01％, 5.21％, 9.25％of the total effect, respectively. Conclusions The posttraumatic growth level of patients with ostomy needs to be improved. Medical staff should strengthen social support for patients and guide patients to adopt the positive coping styles, reduce the avoidance and resignation coping styles, and promote patients to get more posttraumatic growth, furthermore, improve their social adaptability and quality of life.

Objective To evaluate the feasibility of the lateralization of unilateral medial temporal lobe epilepsy(mTLE)by using arterial-spin-labeling(ASL)based perfusion MR imaging and investigate the changes of perfusion in the regions related to mTLE network and the relationship between the perfusion and the clinical status.Methods Twenty-five patients with left-sided and 23 with right-sided mTLE were enroiled,and 30 healthy volunteers were recruited.The cerebral blood flow(CBF)of related region was measured based on pulsed-ASL sequence on Siemens 3 T scanner.The CBF of the mTLE group were compared with that in the controls by using ANOVA analysis.The asymmetric indices of CBF in the medial temporal lobe were calculated as the lesion side compared with the normal side in matched region in mTLE group.Results Compared with the volunteers,the patients with mTLE showed the decrease of CBF in the bilateral medial and lateral temporal,the frontal and parietal regions relating to the default-mode network and more serious in lesion side.The CBF values of the medial temporal lobe were negatively correlated with the epilepsy duration(r =-0.51,P ＜0.01).The asymmetric index of CBF as-0.01 has a 76.0％(19/25)sensitivity and a 78.3％(18/23)specificity to distinguish the lesion side.Conclusions The decrease of CBF in the temporal and extra-temporal region by ASL-based MRI suggests the functional abnormalities in the network involved by mTLE.The ASL technique is a useful tool for lateralizing the unilateral mTLE.
