RESUMEN
OBJECTIVE: To analyze the relationship between clinical characteristics and postoperative complications in patients with hilar cholangiocarcinoma(HCCA) who underwent major liver resection(MLR).METHODS: Clinical characteristics and postoperative complications of 335 patients with HCCA who underwent MLR from January 2010 to October 2017 were retrospectively analyzed.According to the severity of complications,the patients were divided into two groups:low clavien-dindo group(LCD)and high clavien-dindo group(HCD).RESULTS: There were 219 patients in LCD group and 116 patients in HCD group.Elevated INR,Bismuth Ⅲa/Ⅳ type and the right liver/expanding right/right trilobites resection were high risk factors of postoperative serious complications.The incidence of severe postoperative complications in the group with preoperative biliary drainage was 34.18%(67/196),which was not statistically significant different from that in the group without preoperative biliary drainage [35.25%(49/139),P=0.8396].The dose-response curve and Logistic regression indicated that there was a statistical difference in postoperative complication risk between patients with total bilirubin(TB)<140 mol/L and patients with TB≥ 140 mol/L(OR=1.917,95% CI 1.147~3.203,P=0.0130).After statistical correction,the statistical correlation remained,among which,the preoperative biliary drainage rate was 59.2%(151/255) in the group with TB<140 mol/L,and 56.3%(45/80)in the group with TB≥ 140 mol/L.CONCLUSION: In patients with HCCA combined with MLR,patients with TB ≥ 140 mol/L should be routinely treated with preoperative biliary drainage.Especially for the right liver resection,preoperative high INR patients,more attention should be paid to.METHODS: of preoperative biliary drainage have no significant effect on the overall postoperative complications and can be flexibly selected according to the needs of the disease.

@#Objective To explore the effect of pulmonary rehabilitation on activities of daily living(ADL)and pulmonary function in patients with chronic schizophrenia complicated with pulmonary infection at stable stage. Methods From January,2014 to July,2017,62 patients with chronic schizophrenia complicated with pulmonary infec-tion at stable stage were randomly divided into control group(n=31)and observation group(n=31).Both groups accepted routine medication,while the observation group received pulmonary rehabilitation for two months in ad-dition.The distance of 6-Minute Walk Test(6MWT),the modified Barthel index(MBI),modified British Medi-cal Research Council Dyspnea Scale (mMRC), C-reactive protein (CRP), Zung Anxiety Self-Rating Scale and Zung Depression Self-Rating Scale were compared before and after training. Results The total effective rate was higher in the observation group than in the control group(χ2=5.415,P=0.020).Com-pared with the control group,the distance of 6MWT increased(t=5.463,P=0.008),the score of MBI increased(t=2.142, P=0.028), the score of mMRC decreased (t=3.689, P=0.013), and the level of CRP decreased (t=-2.179,P=0.031)in the observation group.The scores of Zung Anxiety Self-Rating Scale(t=5.048,P=0.009) and Zung Depression Self-Rating Scale(t=-1.388,P=0.045)both decreased. Conclusion An early implementation of pulmonary rehabilitation could improve ADL and the exercise endurance,and reduce the incidence of infection in patients with chronic schizophrenia complicated with pulmonary infection at stable stage.
RESUMEN
In this paper, we propose a visual saliency detection algorithm to explore the fusion of various saliency models in a manner of bootstrap learning. First, an original bootstrapping model, which combines both weak and strong saliency models, is constructed. In this model, image priors are exploited to generate an original weak saliency model, which provides training samples for a strong model. Then, a strong classifier is learned based on the samples extracted from the weak model. We use this classifier to classify all the salient and non-salient superpixels in an input image. To further improve the detection performance, multi-scale saliency maps of weak and strong model are integrated, respectively. The final result is the combination of the weak and strong saliency maps. The original model indicates that the overall performance of the proposed algorithm is largely affected by the quality of weak saliency model. Therefore, we propose a co-bootstrapping mechanism, which integrates the advantages of different saliency methods to construct the weak saliency model thus addresses the problem and achieves a better performance. Extensive experiments on benchmark data sets demonstrate that the proposed algorithm outperforms the state-of-the-art methods.
RESUMEN
To study the anti-coagulant effect and influence of danggui Sini decoction (DSD) on rat's plasma endogenous metabolites by animal experiment and ¹H-NMR based metabolomics method. After intragastric administration of Danggui Sini Decoction for 7 days, Plasma thrombin time (TT) was measured. Rat plasma metabolic fingerprint in two groups was analyzed using ¹H-NMR, based on which the principal component analysis( PCA) and orthogonal partial least-squares discriminant analysis(OPLS-DA) models for metabonomic analysis. Potential biomarkers were screened by using variable importance in the projection (VIP) and T test. DSD could prolong TT of the rat significantly (P < 0.05). Compared with control group, six kinds of endogenous metabolites in DSD group change significantly (P < 0.05), among which isobutyrate, carnitine and phenylalanine content had an upward trend (P < 0.01) and lysine, Histidine and cholesterol content had a downward trend (P < 0.05). It is likely that carnitine, phenylalanine, Histidine and cholesterol are the potential metabolic markers in the anti-coagulant process and DSD affects the platelet aggregation and the expression of tissue factor and fiber protease by regulating the energy, amino acid and lipid metabolism.

<p><b>OBJECTIVE</b>To evaluate computed tomography (CT) and magnetic resonance imaging (MRI) findings in patients with autoimmune pancreatitis (AIP).</p><p><b>METHODS</b>The imaging findings of pancreas and extra-pancreas in 24 patients with AIP were retrospectively reviewed. Among them, CT scan was performed in 18 patients, MRI in 11, and bGth CT and MRI in 10.</p><p><b>RESULTS</b>The pancreas showed diffuse enlargement (25%, 6/24), focal enlargement (37. 5%, 9/24), combined enlargement (25%, 6/24) ,and no enlargement (12. 5%, 9/24). Unenhanced CT showed hypoattenuation in AIP area (n = 2) . After intravenous injection of contrast medium, 17 patients showed abnormal contrast enhancement in the affected pancreatic parenchyma, including hypoattenuation during the arterial phase (50%, 9/18) and hyper attenuation during the delayed phase (94. 4%, 17/18). Precontrast MRI showed abnormal signal intense (n =9), including hypointense on T1-weight images (T1 WI) (n = 7), hyperintense (n = 7) and hypointense (n = 2) on T2-weight images (TIWI). Enhanced MRI demonstrated abnormal contrast enhancement within lesions (n = 11), including hypoattenuation during the arterial phase (81. 8%, 9/11) and good enhancement during the delayed phase (100%, 11111). A capsule-like rim was seen around pancreas (37. 5%, 9/24), among which CT detected in 6 out of 18 patients and MRI found in 7 out of 11 patients.The main pancreatic duct lumen within lesions has no visualization (100%, 24/24) and upstream dilation of the main pancreatic duct (n = 8) , ranging from 2. 2 to 4. 5 mm(mean 3. 1 0. 47 mm) in diameter. Narrowing of the common bile duct was shown in 14 patients. Miscellaneous findings were: infiltration of extrapancreatic vein (n = 9) and artery (n = 1); mild fluid collection around pancreas (n = 2); pseudocysts (n = 3). Fourteen patients also presented one or more of the following extrapancreatic imaging findings: narrowing of the intra-hepatic bile duct or hilar duct (n = 5); thickening of gallbladder wall (n = 5); fibrosis in mesenteric (n = 2), in retroperitoneal (n = 2) and in ligamentum teres hepatis (n = 1); renal involvement (n = 3); peri-pancreatic or para-aortic lymphadenopathy (n = 10); and ulcerative colitis (n = 3).</p><p><b>CONCLUSION</b>AIP display some characteristic CT and MRI imaging features: sausage-like change of the pancreas; capsule-like rims around lesions; delayed contrast enhancement in the affected pancreatic parenchyma; segment or diffuse pancreatic duct stenosis but mild upstream dilation and extrapancreatic organs involvement. CT and MRI findings combining with serological tests and pancreas biopsy can assist physicians to make accurate and timely diagnosis.</p>

<p><b>OBJECTIVE</b>To evaluate the application of (18)F-FDG PET/CT in diagnosis of classic fever of unknown origin.</p><p><b>METHODS</b>A total of 27 consecutive patients with classic fever of unknown origin (FUO) (19 men, 8 women; aged 24-82 y) underwent (18)F-FDG PET/CT scans. The images were interpreted by visual inspection and semiquantitative analysis(standardized uptake value, SUV). Final diagnosis was based on histopathology or clinical follow-up.</p><p><b>RESULTS</b>The cause of FUO was confirmed by followed investigations in 21 of 27 cases after PET/CT scan, including 10 cases of infection, 4 of noninfectious inflammation, 4 of malignancies and 3 of miscellaneous disorders; and remaining 6 cases were still confirmed FUO. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy were 100.0 %, 83.3%, 83.3%, 100.0% and 96.3%, respectively.</p><p><b>CONCLUSION</b>For patients with fever of unknown origin, (18)F-FDG-PET/CT can be a sensitive, reliable imaging modality. It is suggested that (18)F-FDG-PET/CT should be considered earlier in detecting the causes of FUO, which is difficultly diagnosed by conventional modalities.</p>

Objective To explore the effect of astragalus injection with heparin in treatment of children with nephrotic syndrome(NS) whose blood was high coagulable.Methods Seventy-two children suffering from NS, whose blood was high coagulable,were randomly divi-ded into 2 groups. The suffering children of 2 groups were given diuretic and anti-infective and hypotenive drugs, simultaneously taking prednisone 2 mg/( kg?d). In addition, the suffering children of therapeutic group was given astragalus injection 20 mL and heparin 100 IU/kg which were added in the glucose injection 200 mL absorbed by intravenous drop.They had blood test since they had taken the medicine once a day and maintained 2-4 weeks′ time.Results The suffering children′s PLT,febrinogen(Fbg) and prothrombin time(PT) of therapeutic group were all lowered down to normal quantity in 10 days but those of contrastive group in 2 weeks or more. The time of urinary protein′s vani-shing of the therapeutic group averages out to (8.9?4.1) d;but contrastive group became normal after 2 weeks and urinary albumen disa-ppeared in (12.8?6.2) d.Conclusions The astragalus injection with heparin is significant to shortening the course of treatment and redu-cing the relapse and preventing from thrombosis in the treatment of NS of suffering children whose blood is high coagulable.The treatment of anti-coagulation can be one of conventional plans.
