ABSTRACT
Objective The study was designed to comparatively analyze ultrasonic appearance,laboratory and pathological findings in autoimmune hepatitis(AIH),and their correlation.The clinical value of ultrasound in diagnosing autoimmune hepatitis was studied.Methods By retrospectively reviewing the ultrasonic images,pathological and laboratory results of 68 patients with autoimmune hepatitis admitted to the PLA 302 Hospital from 2014 to 2015,we tried to reveal the correlation between ultrasonic features and pathological and laboratory findings.Results The ultrasonic diagnosis of liver fibrosis was not statistically correlated with the features of pathological ″interface hepatitis″ and serological liver function test.But it was positively correlated with the features of pathological ″spotty necrosis″(r=0.5099,P ＜ 0.001).The ultrasonic features of ″cord-like structure″ and ″nodular change″ had statistically improved the classification of the degree of AIH fibrosis on ultrasonic diagnosis(t=3.9547,P ＜ 0.01).The ultrasonic feature of the change of ″liver size″ and ″morphology″ also have statistically improved the diagnosis of AIH fibrosis with ultrasonography(t=2.070,2.137,4.584,3.773,all P＜0.05).Conclusion Ultrasonic images could provide objective evidence in diagnosis of AIH and evaluation of fibrosis degree.
ABSTRACT
Objective Through the study of color Doppler ultrasound imaging, to explore the mechanism of portal vein thrombosis for patients with liver cirrhotic portal hypertension splenectomy and its influencing factors. Methods From January 2013 to December 2013, a total of 284 cases of patients with cirrhosis and portal hypertension plenectomy plus pericardial devascularization in 302 Hospital of PLA were reviewed. Color Doppler ultrasound technique was employed to record the thrombosis of portal vein, splenic vein and superior mesenteric vein before and after the surgical procedure. According to the occurrence of portal vein thrombosis after splenectomy, patients were divided into portal vein thrombosis group and non portal vein thrombosis group; the factors that may affect the formation of portal vein thrombus were analyzed by using Logistic regression. Results One hundred and twenty-nine cases of portal vein thrombosis occurred among the 284 patients with splenectomy, the incidence rate was 45.42% (129/284). Logistic regression analysis shows that inner diameters of splenic vein for the group with portal vein thrombosis are significantly different from that of the group without portal vein thrombosis (Z=2.034, P < 0.05), postoperative inner diameter of portal vein (Z=2.037, P<0.05), and prothrombin time (Z=-2.171, P<0.05) are significantly higher in the group with portal vein thrombosis, while preoperative platelet count is significantly lower in the group with portal vein thrombosis (Z=-2.146, P < 0.05); gender, preoperative hepatic artery flow velocity, and blood coagulation time are also the influencing factors of portal vein thrombosis (all P>0.05). Conclusion Color Doppler ultrasound technology can not only monitor, the thrombus formation in portal venous system post splenectomy, it can assess the risk factors of portal vein thrombosis post splenectomy.
ABSTRACT
Objective To explore the clinical value of virtual touch quantification (VTQ) technique in assessing the hepatic fibrosis. Methods A total of 115 inpatients with chronic liver disease receiving liver biopsy were enrolled in this study, all patients liver tissue was checked by VTQ technique, and the results were compared with those of the control group including 80 healthy subjects. Results VTQ value was significantly different between the two groups (P = 0.0000).The VTQ value among different degree of hepatic fibrosis but between S0 and S1 had statistical significances (P = 0.0212, P = 0.0000).ROC curve displayed that VTQ value of 1.4 m/s could be used to diagnose middle-high-grade liver fibrosis, the sensitivity and specificity were 85.4 % and 64.7%, respectively. Conclusions VTQ can be used as a noninvasive and effective means for assessing the degree of hepatic fibrosis.
ABSTRACT
Objective To explore the clinical value of virtual touch quantification technique(VTQ)and fibroscan technique for the diagnosis of hepatic fibrosis.Methods A total of 1 02 patients with chronic liver disease and 78 normal individuals were enrolled in the study.They were all examined with VTQ and fibroscan technique.Pathological results were used as standard criterion.Results The liver tissue riqidity was associated with pathological results.The coefficient of relativity was 0.43309(VTQ)and 0.35840(Fibroscan).ROC curve displayed that VTQ value of 1.4 m/s and fibroscan value of 7.75 kPa can be used to differential diagnose the lowgrade liver fibrosis and high-grade liver fibrosis.The probability of success was 100 0A(102/102)and 100%(78/78)by VTQ,but 88%(90/102)and 100%(78/78)by fibroscan technique.Conclusions VTQ and fibroscan technique are useful in the diagnosis of hepatic fibrosis.Compared with fibroscan technique,VTQ has more advantages in sensitivity practicability and convenience.
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the relationship between hepatitis B and gallstones using epidemiological methods.</p><p><b>METHODS</b>The analysed data from 510 patients with hepatitis B and 359 patients with other diseases treated in our hospital from the period January 1998 to June 2001 were retrospectively analysed. The patients with hepatitis B were classified into groups. The incidence of gallstones was determined in each group. Queue study method was used to calculate RR in each group and statistical analysis was conducted to determine difference among different groups.</p><p><b>RESULTS</b>As compared the patients gallstone with the patients with other diseases RR in those with hepatitis B (including those with chronic hepatitis or liver cirrhosis) was significantly higher (P<0.01). The value of RR was not markedly increased in patients with acute hepatitis or cholestatic hepatitis. After long-term administration of Chinese herbal medicine, the incidence of gallstones in patients with hepatitis B was decreased.</p><p><b>CONCLUSIONS</b>Chronic pathological changes in patients with hepatitis B may be one of the causes for gallstones. This may provide epidemiological basis for prevention and treatment of gallstones.</p>
