Complete blood counts, liver function, platelet indices(MPV), coagulation parameters, lactate dehydrogenase(LDH) and C-reactive protein(CRP) were measured on days 1, 2, 3 and 7 after admission. Receiver operating characteristic curves were used to compare the sensitivity and specificity of MPV, white blood cell(WBC), LDH and CRP in predicting AP severity. The Modified Glasgow Prognostic Score(m GPS) and the 2012 revised Atlanta criteria were used to evaluate disease severity in AP.RESULTS MPV levels were significantly lower in the AP group than in the control group on day 1(P = 0.000), day 2(P = 0.029) and day 3(P = 0.001) after admission.In addition, MPV values were lower on day 1 after admission than on day 2(P = 0.012), day 3(P = 0.000) and day 7(P = 0.002) in all AP patients. Based on the m GPS, 78 patients(66.7%) were diagnosed with mild and 39 patients(33.3%) with severe AP. There was no significant difference in mean MPV levels between patients diagnosed with mild and severe AP based on the m GPS(P = 0.424). According to the 2012 revised Atlanta criteria, there were 98 patients(83.8%) without persistent organ failure(OF) [non-severe acute pancreatitis(non-SAP) group] and 19 patients(16.2%) with persistent OF(SAP group). MPV levels were significantly lower in the SAP group than in the non-SAP group on day 1 after admission(P = 0.002). On day 1 after admission using a cut-off value of 6.65 f L, the overall accuracy of MPV for predicting SAP according to the 2012 revised Atlanta criteria(AUC = 0.716) had a sensitivity of 91.8% and a specificity of 47.4% and was superior to the accuracy of the traditional markers WBC(AUC = 0.700) and LDH(AUC = 0.697).CONCLUSION MPV can be used at no additional cost as a useful, noninvasive biomarker that distinguishes AP with persistent OF from AP without persistent OF on day 1 of hospital admission.展开更多

Random-effects models were used to calculate summary odds ratios (ORs) with 95%CIs for the highest vs lowest category of exposure. Heterogeneity was assessed by using the Q test and I<sup>2</sup> statistic. Subgroup analyses were also performed to test for potential source of heterogeneity.RESULTSA total of 14 case-control studies were included. Ten studies on CRP including a total of 3350 cases and 4168 controls showed non-significant summary (OR = 1.23, 95%CI: 0.98-1.54; I<sup>2</sup> = 54%, P<sub>heterogeneity</sub> = 0.01) in the general analysis, but significant increased odds when considering only advanced adenoma (OR = 1.59, 95%CI: 1.09-2.32; I<sup>2</sup> = 44%, P<sub>heterogeneity</sub> = 0.15). Subgroup and stratified analyses revealed a potential influence of smoking status and aspirin use on the association between CRP levels and colorectal adenoma. Five studies examined the association between circulating levels of TNF-α and colorectal adenoma risk, including a total of 1,568 cases and 2,832 controls. The summary OR for the highest vs the lowest category of exposure was 1.00 (95%CI: 0.77-1.29). The relationship between circulating IL-6 levels and colorectal adenoma risk was investigated in 7 studies including a total of 1936 cases and 3611 controls. The summary OR for the highest vs the lowest category of exposure was 1.19 (95%CI: 0.92-1.55).CONCLUSIONSummary of current evidence suggests a positive association of CRP levels and advanced colorectal adenoma risk. The role of potential confounding factors should be further evaluated.展开更多

The aim of this study was to determine the role of oxygen free radicals in patients with acute pancreatitis. METHODS:The plasma levels of C-reactive protein(CRP), lipid peroxide(LPO),myeloperoxidase(MPO)and superoxide dismutase(SOD)were measured in 13 patients with acute pancreatitis and 14 healthy volunteers. RESULTS:Among the patients with acute pancreatitis,there were higher plasma levels of LPO and MPO and lower SOD activity in patients with severe pancreatitis than in those with mild pancreatitis.However,there was no significant difference in the serum marker of oxidative stress no matter what the etiology was.The LPO level was especially correlated with the concentration of serum CRP and CT severity index. CONCLUSION:The oxygen free radicals may be closely associated with inflammatory process and the severity of acute pancreatitis.Especially,the concentration of plasma LPO is a meaningful index for determining the severity of the disease.展开更多

The numbers of different subsets of monocytes were examined in these two groups of subjects by flow cytometry. The concentrations of plasma interleukin(IL)-10 and IL-12 were determined by cytometric bead array. The acute physiology and chronic health evaluation(APACHE) II scores of individual patients were evaluated, and the levels of plasma C-reactive protein(CRP) as well as the activities of amylase and lipase were measured. RESULTS In comparison with that in the controls, significantly increased numbers of CD14+CD163-, CD14+CD163-MAC387+ M1 monocytes, but significantly reduced numbers of CD14+CD163+IL-10+ M2 monocytes were detected in the MAP patients(P < 0.01 or P < 0.05). Furthermore, significantly higher levels of plasma IL-10 and IL-12 were observed in the MAP patients(P < 0.01 for all). More importantly, the levels of plasma CRP were positively correlated with the numbers of CD14+CD163-(R = 0.5009, P = 0.0127) and CD14+CD163-MAC387+(R = 0.5079, P = 0.0113) M1 monocytes and CD14+CD163+CD115+ M2 monocytes(R = 0.4565, P = 0.0249) in the patients. The APACHE II scores correlated with the numbers of CD14+CD163+CD115+(R = 0.4581, P = 0.0244) monocytes and the levels of plasma IL-10(R = 0.4178, P = 0.0422) in the MAP patients. However, there was no significant association among other measures tested in this population. CONCLUSION Increased numbers of CD14+CD163- and CD14+ CD163-MAC387+ monocytes may contribute to the pathogenesis of MAP, and increased numbers of CD14+CD163+CD115+ monocytes may be a biomarker for evaluating the severity of MAP.展开更多

Simple immune agar diffusion test was used to assay the contents of 12 plasma proteins in 70 cases of chronic pulmonary heart disease treated by Huang Qi Wu Wu Decoction (黄芪五物汤), with the other 70 cases who were not given Huang Qi Wu Wu Decoction as the control group. The total clinical effective rate in the treatment group was 90.0%, while that in the control group was 75.7%, with a statistically significant difference between the two groups (P<0.05). In the treatment group, the levels of prealbumin, transferrin and fibronectin elevated obviously after treatment, and the contents of C-reactive protein, ceruloplasmin, haptoglobin, a 1-antitrypsin and a 1-acid glycoprotein decreased markedly (P<0.01). In the control group, only the levels of ceruloplasmin and C-reactive protein decreased significantly (P<0.05). It is shown that Huang Qi Wu Wu Decoction may enhance the therapeutic effects for pulmonary heart disease, regulate the metabolism of plasma proteins, and improve the life quality of the patients.展开更多
