Objective:To establish a preoperative forecasting model for the nature of duodenal papillary tumors and to discuss its main predictors.Methods:A case-control study was conducted;the case group included patients with malignant duodenal papillary tumors and the control group included patients with benign duodenal papillary tumors.All the patients were from Changhai Hospital. Data of patients,including the demographic characteristics,clinical symptoms during onset,laboratory findings,and radiological data, were collected by face-to-face interviews or by reviewing the medical history.Chi-square,t-test or ANOVA were employed to performed univariate analysis.All factors with P values less than or equal to 0.25 in the univariate analysis were used as independent variables for multivariate analysis,and a Logistic regression forecasting model for the nature of duodenal papillary tumors was established.Results: Totally 199 patients with pathologically-confirmed duodenal papillary tumors were included in the present study,with 166 in the case group and 33 in the control group.Multivariate analysis showed that hemoglobin(Hb),total bilirubin(Tbil),direct bilirubin(Dbil), aspartate transferase(AST),alkaline phosphatase(AKP),gamma glutamyl transpeptidase(GGT),and carcinoembryonic antigen(CEA) were independent predictors for nature of duodenal papillary tumors,with their odds ratios(95% confidence interval)being 0.981 (0.959,1.003),0.867(0.794,0.948),1.207(1.075,1.355),1.028(1.008,1.048),0.996(0.992,1.000),1.002(1.000,1.004),and 0.974(0.953,0.994),respectively.Conclusion:The Logistic regression model,which takes into consideration of Hb,Tbil,Dbil,AST, AKP,GGT,and CEA,can be used to predict the nature of duodenal papillary tumors,and its clinical value need to be further studied.

This study is to investigate the protective effect of mangiferin on NF-kappaB (P65) and IkappaBalpha expression in peripheral blood mononuclear cell (PBMC) in rats with cigarette smoke induced chronic bronchitis. The rat model with chronic bronchitis was established by cigarette smoke. Real-time fluorescence RT-PCR was executed for evaluating the NF-kappaB (P65) and IKkappaBalpha gene expression in mononuclear cell, and flow cytometry for their protein expression. The serum hs-CRP (high-sensitivity C-reactive proteins) and TNF-alpha (tumor necrosis factor-alpha) were detected by enzyme-linked immunosorbent assay. The histopathological score was obtained from lung tissue HE staining slides of lung tissue. The results showed that mangiferin could markedly suppress the NF-kappaB (P65) mRNA and protein expression in mononuclear cell, while promote the IkappaBalpha mRNA and protein expression. Furthermore, mangiferin could lower serum hs-CRP and TNF-alpha level, and reduce the chronic inflammatory damage of bronchiole. These results suggested that mangiferin could notably ameliorate chronic bronchiole inflammation induced by cigarette smoke, and this protective effect might be linked to the regulation of NF-kappaB (P65) and IkappaBalpha expression in mononuclear cell.

Bacillus cereus B-04 antagonist to Botrytis cinerea were isolated from samples of tomato soil infected by Botrytis cinerea in Zibo, which are identified through a series of morphological and biochemical characteristics and the sequence of 16SrDNA. Aiming at enhancing the inhibitory effect of this strain, a 4.1kb DNA fragment containing ?-1,3-glucanases gene from pUC1940 was inserted into vector pBE2 and pHY300PLK to construct recombination plasmids, PBE2-glu and pHY300PLK-glu, which were transferred into Bacillus cereus B-04, resulting in a new strain named B-04-glu. Restriction enzyme digestion and ?-1,3-glucanases plate culture confirmed that B-04-glu contained a functional ?-1,3-glucanases gene. Compared to the wild strain B-04, B-04-glu had an increased inhibitory effect against Botrytis cinerea on tomato.

Objective To evaluate the activation of premotor area (PMA) in verb generation task, and to discuss the possible function of PMA in language expression. Methods Block-designed fMRI with verb generation task was performed on 23 subjects with GE 1.5T MR Scanner. During the test, the subjects were asked to generate a verb based on a given noun word. The white + appeared on the center of the black screen was used as control. The fMRI data were processed with SPM 2. Group analysis was performed with single sample t-test. Average mapping was obtained and overlapped onto standard MNI template. Activation of the PMA was analyzed. Results The fMRI data of eleven subjects were selected for group analysis after head motion effect was ruled out. Average mapping showed activation in the Broca's area, posterior part of the right inferior frontal gyrus, bilateral PMA and supplemental areas (SMA), left posterior parietal cortex, right thalamus, left basal ganglions, right cerebellum, and posterior part of the right temporal lobe. The area with the greatest activated intensity in the brain was the left PMA. Conclusion PMC is important in verb generation and may be responsible for voice processing, motor imagery, word extracting as well as advanced regulation of information.

Objective To observe responses of brain evoked by somatic stimuli in healthy subjects with blood oxygenation level-dependent functional magnetic resonance imaging.Methods There were 30 healthy subjects in the study. Block design was used infunctional MR imaging. In experimental tasks somatic stimuli was executed to the hands of every subject at duration 1000 ms,interstimulus intervals 1000 ms.The professional software-SPM99 was performed to process the images.Results For healthy subjects to somatic stimuli, significant activation was observed in bilateral primary and secondary somatic cortex of precentral gyri and postcentral gyri, and temporallobes. Scattered activations could be seen in frontal lobes, supramarginal gyri and hemisphere of cerebella. There was more intensiveactivation in right hemisphere than that in left. There was no significant difference between the activation evoked by somatic stimuli of leftand right extremities. Conclusion somatic stimuli can evoke significant activations in bilateral primary and secondary somatic cortex.Temporal lobes and other brain areas join in the process of somatic stimuli.

Objective To study the role of prefrontal cortex in maintenance of working memory(WM)using event-related functional MRI(ER-fMRI).Methods Twenty healthy subjects completed a relative lower,high load version of the sternberg item recognition task during ER-fMRI.The brain areas showing activity on average across the two loads for maintenance phase were obtained with group analysis.Load dependent activity was identified with inter-group analysis.Results The maintenance phase were relevant to the activity in dorsolateral prefrontal cortex(DLPFC),ventrolateral prefrontal cortex(VLPFC),parietal lobe,supplementary motor area(SMA)and premotor cortex(PMA).Brain regions including VLPFC showed increased activation for high load level.Conclusion Functional difference but not anatomic difference between maintenance and manipulation in brain may be exist.

ObjectiveTo assess the value of the area of ground glass opacities (GGOs) in lungs displayed by high-resolution computed tomography (HRCT) in paraquat (PQ) poisoned patients in evaluating prognosis. Methods Clinical and imaging data of 137 patients with acute PQ poisoning admitted to Affiliated Hospital of the Medical College of Chinese People's Armed Police Forces from January 2012 to August 2014 were analyzed retrospectively. The plasma concentration of PQ on admission and the area of GGOs were compared between two groups. The lung HRCT within 10 days of poisoning was performed every 3 days, and the areas of GGOs were evaluated on five levels, including aortic arch, aortic pulmonary window, left upper lobe bronchial, right inferior pulmonary vein, and left diaphragmatic dome. Receiver operating characteristic curve (ROC) was plotted to evaluate the value of all the parameters for prognosis.Results Among 137 patients, 45 died within 28 days after poisoning, with the mortality rate of 32.85%. The plasma PQ level in the non-survivors was significantly higher than that in the survivors (mg/L:7.06±0.67 vs. 3.51±0.34,t = 5.280,P = 0.000). The areas of GGOs at three time points in the non-survivors were significantly higher than those in the survivors [1-3 days: (32.0±5.0)% vs. (2.5±0.4)%,t = 7.860,P = 0.000;4-6 days: (45.5±5.7)% vs. (2.8±0.5)%,t = 12.420,P = 0.000; 7-10 days: (68.0±4.8)% vs. (3.0±0.6)%, t = 23.950,P = 0.000]. ROC analysis demonstrated that the area under the ROC curve (AUC) of GGOs in 7-10 days was 1.000, which could be used to determine the prognosis, but it was too late for the treatment. The AUC of GGOs in 4-6 days was 0.979, with the threshold of> 12.0%, the specificity of 96.15%, the sensitivity of 85.19%, the positive predictive value of 88.46%, and the negative predictive value of 94.94%, which presented good effect in predicting prognosis in the early stage of acute PQ intoxication. But plasma PQ concentration was relatively poor for determining prognosis, AUC was 0.821, with the threshold of> 1.95 mg/L, the specificity of 34.52%, the sensitivity of 88.64%, the positive predictive value of 41.49%, and the negative predictive value of 85.29%.Conclusions The area of GGOs displayed by HRCT can be used to evaluate the fully developed acute PQ lung injury, and it is superior to plasma PQ concentration. The area of GGOs displayed by HRCT 4-6 days after intoxication can be used for the evaluation of PQ induced pulmonary injury in the early stage and the evaluation of clinical prognosis.

Objective:The objective of this research is to study the serum level of the high-mobility group protein B1 (HMGB1) in human ovarian tumor (OvCa) and in a healthy control. This study also aims to identify different HMGB1 levels before and after sur-gery and to explore the inhibitory effect of HMGB1 gene silencing in the proliferation and invasion ability of OvCa. Methods: En-zyme-linked immunosorbent assay was used to measure the serum level of HMGB1 in OvCa patients and healthy subjects. Lentivirus vector with HMGB1 shRNA was constructed and used to infect OvCa cells. The expressions of HMGB1 mRNA and protein were test-ed by real-time PCR and Western blot. Cell proliferation was detected using the Cell Counting Kit-8 assay, whereas cell invasion and migration were detected by Transwell assay. Results:The serum level of HMGB1 was more elevated in patients with malignant diseas-es compared with individuals with benign diseases and the control groups. In the malignant group, the serum level of HMGB1 de-creased noticeably after therapy. Down-regulation of HMGB1 expression resulted in the inhibition of the biological behavior and metas-tasis of ovarian cancer cells. Conclusion: HMGB1 is closely associated with clinicopathologic features of OvCa. Knockdown of HMGB1 expression can significantly inhibit cell proliferation, cell migration, and cell invasion of OvCa. These findings indicate that HMGB1 can function as a therapeutic target for ovarian neoplasm in the future.
