METHODSConsecutive patients with IBD aged 18 years or older were enrolled in the study. Forty-seven patients with ulcerative colitis (UC), 38 with Crohn’s disease (CD), and 50 healthy controls were included. The white blood cell count, haematocrit, platelet count, fibrinogen, partial activated thromboplastin time, C-reactive protein, albumin, VWF antigen level (VWF:Ag), VWF ristocetin cofactor activity (VWF:RCo), VWF collagen-binding activity (VWF:CB), and ADAMTS13 antigen level (ADAMTS13:Ag) and activity (ADAMTS13act) were measured. The following ratios were assessed: VWF:RCo/VWF:Ag, VWF:CB/VWF:Ag, VWF:Ag/ADAMTS13act, and ADAMTS13act/ADAMTS13:Ag. RESULTSCompared to controls, the odds ratio (OR) of an elevated VWF: Ag > 150% was 8.7 (95%CI: 2.7-28.1) in the UC group and 16.2 (95%CI: 4.8-54.0) in the CD group. VWF:CB was lower in UC patients, and active CD was associated with a higher VWF: RCo (+38%). The ORs of VWF:CB/VWF:Ag < 0.7 (a marker of acquired von Willebrand syndrome) in the UC and CD groups were 11.9 (95%CI: 4.4-32.4) and 13.3 (95%CI: 4.6-38.1), respectively. Active UC was associated with lower ADAMTS13:Ag (-23%) and ADAMTS13act (-20%) compared to UC in remission. Patients with active CD had a 15% lower ADAMTS13act than controls. The activity of UC, but not that of CD, was inversely correlated with ADAMTS13:Ag (r = -0.76) and ADAMTS13act (r = -0.81). CONCLUSIONComplex VWF-ADAMTS13-mediated mechanisms disturb haemostasis in IBD. A reduced WVF:CB is a risk factor for bleeding, while a lower ADAMTS13 level combined with an elevated VWF:Ag could predispose one to thrombosis.展开更多

According to recent reports, this drug has been used to treat herpes zoster, hepatitis B, parotitis, nephrotic syndrome, acute conjunctivitis, recurrent aphtha, urticaria, etc.1 with good therapeutic effects. More than half of the AIDS patients suffered from herpes zoster. The area of skin lesion in AIDS patients is larger than that of the patients without AIDS and the pain lasts longer. Many cases have keloids and depigmentation for months, even severe pain till their death. Routine therapeutic methods are not satisfactory in therapeutic effects. The expert group of traditional Chinese medicine for cooperative research on AIDS used Ji De Sheng She Yao tablets (季德胜蛇药片) to treat AIDS complicated by herpes zoster for the first time and the results are reported as follows.展开更多

Methods: Twenty-nine HIV-infected patients were treated with ZY-2 for 3 months as one treatment course; and viral load, immune function and symptoms-signs were determined before and after treatment. Results: After treatment, the absolute values of CD4 were elevated in 8 cases, and lowered in 14 cases, 7 cases were not changed; the ratio of CD4/CD8 were elevated in 2 cases, lowered in 1 case, 16 of them were not changed obviously. The CD4 and CD4/CD8 ratio were elevated simultaneously in 2 cases. Neopterin lowered in 4 cases, elevated in 11 cases, and not changed in 1 case. Viral load (VL) was lowered in 6 cases, elevated in 8 cases and not changed in 2 cases. The total effective rate was 42.28% on the basis of comprehensive assessment of VL, immune function, body weight and symptoms-signs. Conclusion: ZY-2 is an effective Chinese recipe in treating HIV-infected patients.展开更多

METHODSA literature search was performed on MEDLINE and Google Scholar databases from 2000 to 15<sup>th</sup> of November 2016, using the following search strategy: “spontaneous” AND “peritonitis”. RESULTSThe initial search through electronic databases retrieved 2556 records. After removing duplicates, 1958 records remained. One thousand seven hundred and thirty-five of them were excluded on the basis of the screening of titles and abstract, and the ensuing number of remaining articles was 223. Of these records, after careful evaluation, only 9 were included in the qualitative analysis. The overall proportion of MDR bacteria turned out to be from 22% to 73% of cases across the studies. CONCLUSIONN-SBP is caused, in a remarkable proportion, by MDR pathogens. This should prompt a careful re-assessment of guidelines addressing the treatment of this clinical entity.展开更多

The patient was admitted to our hospital with a persistent perianal abscess that was refractory to antibiotic therapy adminis-tered at another hospital. On admission, we observed a giant ulcer in the perianal region. At first, cytomega-lovirus colitis was suspected by blood investigations. Ganciclovir therapy was initiated; however, the patient developed necrosis of the skin around the anus during therapy. We only performed end-sigmoidostomy and necrotomy to avoid excessive surgical invasion. Histopathological examination of the surgical specimen revealed the presence of trophozoite amoebae, indicating a final diagnosis of acute fulminant amoebic colitis. The patient's postoperative course was favorable, and proctectomy of the residual rectum was performed 11 mo later. Amoebic colitis is one of the most severe complications affecting patients with AIDS. Particularly, acute fulminant amoebic colitis may result in a poor prognosis; therefore, staged surgical therapy as a lessinvasive procedure should be considered as one of the treatment options for these patients.展开更多

The performance for predicting short-term mortality was calculated for Chronic Liver FailureSequential Organ Failure Assessment(CLIF-SOFA), CLIF Consortium Organ Failure score(CLIF-C OFs), Maddrey'sdiscriminant function(DF), age, bilirubin, international normalized ratio and creatinine score(ABIC), Glasgow Alcoholic Hepatitis Score(GAHS), model for end-stage liver disease(MELD), and MELD-Na.RESULTS Of 264 patients, 32(12%) patients died within 28 d. The area under receiver operating characteristic curve of CLIF-SOFA, CLIF-C OFs, DF, ABIC, GAHS, MELD, and MELD-Na was 0.86(0.81-0.90), 0.89(0.84-0.92), 0.79(0.74-0.84), 0.78(0.72-0.83), 0.81(0.76-0.86), 0.83(0.78-0.88), and 0.83(0.78-0.88), respectively, for 28-d mortality. The performance of CLIF-SOFA had no statistically significant differences for 28-d mortality. The performance of CLIF-C OFs was superior to that of DF, ABIC, and GAHS, while comparable to that of MELD and MELD-Na in predicting 28-d mortality. A CLIF-SOFA score of 8 had 78.1% sensitivity and 79.7% specificity, and CLIF-C OFs of 10 had 68.8% sensitivity and 91.4% specificity for predicting 28-d mortality.CONCLUSION CLIF-SOFA and CLIF-C OF scores performed well, with comparable predictive ability for short-term mortality compared to the commonly used scoring systems in patients with alcoholic hepatitis.展开更多

This paper proposes two new approaches for the assessment of the weights to be associated with fuzzy opinions. These approaches involve,respectively,the minimization of the sum of squared differences between the individual weighted fuzzy opinion and the weighted mean value of all fuzzy opinions,which is called the weighted minimum variance method (WMVM),and the minimax difference of any two adjacent individual weighted fuzzy opinions,which is called the mean value minimax differences method (MVMDM). The two approaches are developed and numerical examples are presented to illustrate their simplicity and effectiveness in aggregating fuzzy opinions.展开更多
