ABSTRACT
Objective To detect the level of CD64 and serum procalcitonin (PCT ) and investigate the diagnosis value of CD64 and serum PCT in cirrhosis patients with spontaneous bacterial peritonitis (SBP) .Methods Participants were categorized in‐to three groups including liver cirrhosis with SBP(45 patients) ,liver cirrhosis without SBP(93 patients) and health personnel(50 persons) .CD64 was detected by flow cytometry and serum PCT was measured by electroc hemiluminescence immunoassay .The li‐mosis vein blood samples were obtained from the patients with SBP at the time of 24 h after admission ,before antibacterial drugs use and 7 days after the effective treatment of antibacterial drugs .The CD64 and serum PCT were detected with the limosis vein blood samples .At the same time ,the complete blood count ,liver ,kidney and blood coagulate functions were tested .The participants in other two groups were detected the CD64 ,serum PCT ,complete blood count ,liver ,kidney and blood coagulate functions at the same time .Results The level of CD64 and serum PCT in cirrhosis patients with SBP were significantly higher than those in liver cirrhosis without SBP and normal controls (P< 0 .01) .ROC curve analysis showed that the sensitivity and specificity of CD64 and serum PCT were 95 .5% ,93 .8% and 96 .1% ,85 .2% respectively .Conclusion CD64 and serum PCT can be determined as the im‐portant indicator in early diagnosis and efficacy criterion .
ABSTRACT
Objective To explore the clinical features of patients with surgical malignant peritoneal mesothelioma.Methods From April 2008 to November 2012,the clinical data of 14 patients with surgery and pathologically diagnosed malignant peritoneal mesothelioma were retrospectively analyzed.Results Among the 14 patients,13 cases had a history of asbestos exposure.There were 10 cases with abdominal pain,seven cases with bloatting,and one case with intermittent vaginal bleeding.There were 13 cases with asbestos plaques,14 cases with organ infiltration,nine cases with little or no ascites,one case with mild lymph nodes enlargement in peritoneal cavity,but no case was found with distant metastasis.There were three cases with diffuse type and 11 cases with localized type.Serum CA125 level increased in seven cases.Seven cases received postoperative chemotherapy,and the average survival time was five months after surgery.To the closing date,two patients with localized peritoneal lesions are still alive.Conclusions The incidence of the group of patients with malignant peritoneal mesothelioma is closely related to the contact with asbestos.Localized type is the dominant type,without lymph nodes enlargement and distant metastases.Survival rate may improve in patients with early surgery.
ABSTRACT
Objective To explore the clinical characteristics of localized peritoneal mesothelioma by the retrospective analysis of the clinical data and its relationship with asbestos exposure.Methods A total of 22 cases with localized peritoneal mesothelioma confirmed by pathological test and they were selected as our subjects in the Central Hospital of Cangzhou from Jan.2007 to Dec.2012.The information of all cases was collected.The incidence,asbestos exposure history,clinical manifestations,imaging studies,pathological type,immunohistochemistry and tumor markers of peritoneal mesotheliom patients were recorded or measured.Results Of 22 cases,female accounted for 68.18％.The periods from onset symptoms to treatment time was from 2 days to 1 year with an average of 83 days.Clinical symptoms were verified including localized abdominal pain (11 cases,50.00％),abdominal mass (8 cases,36.36％),abdominal distension (6 cases,27.27％),ascites (10 cases,45.45％).Patient was with increased platelet and carcinoma antigen 125.Abdominal computerized tomography showed that local mass was seen and 12 cases were with asbestos spot.Ultrasound-guided peritoneal biopsy was confirmed as the main diagnostic method followed by Laparotomy.Epithelial type was the main pathological type (19 cases,86.36％),following the fleshy tumor type and mixed type.Eighteen cases had asbestos exposure history.Conclusion Localized peritoneal mesothelioma is a rare disease.However,the incidence is high in the current region due to asbestos exposure.Abdominal pain and local mass are the main clinical symptoms,and the main pathology is epithelial typeas well as surgery is the main therapy.
ABSTRACT
<p><b>OBJECTIVE</b>To compare the application valuable of flexible spatial scan statistics and kulldorff scanning window in the cluster detection and early warning of hepatitis A.</p><p><b>METHODS</b>The case numbers and incidence data of hepatitis A in 2012 for all the counties (cities, districts)in Yunnan province were collected from China Information System for Disease Control and Prevention and the total number was 1 335. By extracting the time length by month, the flexible spatial scan statistics was tested by retrospective analyses of hepatitis A data in Yunnan in 2012 and compared the results with the Kulldorff circular scan statistic analyses.</p><p><b>RESULTS</b>The results of flexible scanning window showed that there were fifteen hepatitis A spatial clusters in Yunnan province in 2012 and in July, these areas including Gejiu county, Mengzi county and Wenshan county had the strongest clusters (the log likelihood ratio (LLR) = 52.66, P = 0.001). The results of Kulldorff scanning window showed that there were twenty hepatitis A spatial clusters and these areas including Gejiu county, Hekou county, Maguan county, Mengzi county, Pingbian county, Wenshan county had the strongest clusters (LLR = 47.82, P = 0.001). The results of the flexible scanning window were the same as the actual monitoring results. But the results of Kulldorff scanning window showed that in May and June some areas without incidence had the clusters.</p><p><b>CONCLUSION</b>Flexible scanning window can detect the monthly clusters of the Hepatitis A. Flexible scanning window had a higher accuracy than Kulldorff irregular circular scanning window. Flexible spatial scan statistics had the value in the use of spatial aggregation detecting on hepatitis A.</p>

Objective To study the role of IL-18 in the pathogenesis and treatment of ulcerative colitis (UC). Method An enzyme-linked immunosorbent assay (ELISA) was utilized to detect the serum IL-18 level of 58 UC patients. Results The serum IL-18 level in acute period of UC patients was significantly higher than that in control ones(P < 0.05 ). There was no significant difference between remisson period of UC and control ones (P> 0.05). The serum IL-18 level was closely related with the degree of UC (P < 0.05),the mean concentration of serum IL-18 was significantly higher in patients with severe ulcerative colitis [ (392.78 ± 50.17)pg/ml]than in patients with mild colitis ulcerative [ (138.92 ± 23.41 )pg/ml]and in control ones. Serum IL-18 in active ulcerative colitis were positively related to clinical disease severity and activity or laboratory parameters,including CAI,serum CRP,erythrocyte sedimentation rates,or total leukocyte counts (r = 0.775,0.705,0.662,0.625,P < 0.01 ). The level of IL-18 was declined after treatment with corticoids(P< 0.05). Conclusions IL-18 might play an important role in the pathogenesis of UC. The measurement of IL-18 is helpful to estimate the disease activity of UC and it may be considered as laboratory and activity criteria for UC.
