ABSTRACT

<p><b>OBJECTIVE</b>To generate a refined staging system of fibrosis in chronic viral hepatitis and to assess its accuracy and sensitivity for evaluating therapeutic efficacy of anti-fibrosis drug treatments.</p><p><b>METHODS</b>A refined fibrosis staging system was established according to the detailed characteristics of progressive fibrosis. A total of 396 liver puncture biopsy specimens were collected from patients before and after anti-fibrosis therapy and used to evaluate the refined staging system. According to the original fibrosis staging system and refined fibrosis staging system, fibrosis staging differences from before and after treatment were analyzed by Chi-squared test and paired-samples t-test respectively.</p><p><b>RESULTS</b>The refined fibrosis staging system detected significant changes in fibrosis stage that occurred in response to treatment (before treatment: 6.55 +/- 2.93 vs. after treatment: 6.19 +/- 2.945, P less than 0.01). However, the original (unrefined) staging system was unable to differentiate therapy-related changes in fibrosis stage (x2= 3.144, P = 0.534).</p><p><b>CONCLUSION</b>The newly-developed refined fibrosis staging system was able to effectively evaluate the therapeutic efficacy of anti-fibrosis drug treatment and performed better than the original staging system.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To elucidate clinical and pathological features of primary sclerosing cholangitis (PSC) in order to improve clinician's awareness of this rare disease.</p><p><b>METHODS</b>We retrospectively analyzed clinical data and follow-up information of 27 PSC patients who were admitted to Beijing Friendship Hospital from January 1990 to November 2009. The patients were classified into classic PSC and small-duct PSC according to biochemistry and imaging results. After 3 to 6 months of therapy, those patients with serum ALT < or = 1.5, TBil < or = 2 and ALP < or = 2.5 ULN were determined as good responders. The treatment results between the two groups were compared.</p><p><b>RESULTS</b>9 out of 27 cases of PSC were small duct PSC and 18 cases were large bile duct or classic PSC. Male patients (7) were less than females (20) and the average age was 47.6 years. Main clinical symptoms included jaundice (85.2%), pruritis (48.1%),fatigue (68.4 %), abdominal pain (40.7%) and fever (14.8%), main physical sign included hepatomegaly (44.4%), splenomegaly (48.1 %) and ascites (14.8%). Laboratory features included elevated IgG (81.8%), positive ANA (69.6%) and pANCA (52.9%). 22% of these PSC patients had ulcerative colitis or Sjogren's syndrome. A small percentage of patients were responsive to standard therapy, of which small duct PSC had a better response than classic PSC (66.7 % vs 33.3%, P = 0.041).</p><p><b>CONCLUSIONS</b>Ulcerative colitis (22.2%) is not as common as reported by western countries. Small duct PSC has a better treatment response. Searching of effective treatment regimen for large bile duct PSC is warranted in future studies.</p>

ABSTRACT

<p><b>OBJECTIVE</b>In China, liver failure is also termed as severe hepatitis in whom chronic severe hepatitis B (CSHB) is most common. The aim of this study was to assess whether CSHB based on different liver injury extent can meet the international definition of acute-on-chronic liver failure(ACLF)criteria, according by their clinical and pathological feature.</p><p><b>METHODS</b>A total of 91 patients with CSHB were involved in the study. The clinical findings, laboratory data and liver pathology features were retrospectively analyzed and grouped by hepatitis virus B carrier state (HBC), chronic hepatitis B (CHB) or liver cirrhosis (LC) before they started liver failure.</p><p><b>RESULTS</b>74 out of the 91 patients were male and 17 were female, the mean age was 40.6+/-11.2 years. 9.9%, 7.7% and 82.4% of the patients were based on HBC, CHB and LC respectively. The ages of HBC group were youngest. The mean age of HBC group (years) (25.8+/-6.6) was significantly lower than that of CHB group (36.9+/-9.0) and LC group (42.0+/-10.5)with P values of 0.032 and 0.001 respectively. Most cases presented with sub-acute liver failure characterized by high icterus and ascites. Predisposing factors included exertion, superinfection, virus variation, drugs or alcoholic injury. No difference found between PTA (F = 0.906, P = 0.408) and TBil (F = 0.839, P = 0.436) among the above three groups. The Alb and CHE levels in LC group were (30.3+/-5.1) g/L and (2926.8+/-1471.1) U/L respectively, which were lower than both HBC group [Alb (35.6+/-5.1) g/L, CHE (4363.5+/-2063.2) U/L] and CHB group [Alb (37.4+/-5.0) g/L, CHE (5167.1+/-1522.1) U/L] (F = 9.450; F = 9.297; P value less than 0.01).The level of CHO (1.8+/-1.0) mmol/L in LC group was lower than that of HBC group (2.9+/-1.0mmol/L, P = 0.034), while serum HBV DNA level of HBC group [(6.8+/-1.7) log10copies/ml] was higher than that of LC group [(4.2+/-2.6) log10copies/ml]. The liver tissue in HBC and CHB group showed massive or submassive necrosis which distribute evenly in different parts of liver and similarly in slides, most like acute/subacute severe hepatitis. The chronic lesion was easily covered by extensive necrosis in CSHB based on CHB, with portal fibrosis can be seen by masson stain. Characteristic picture of LC group were massive or submassive necrosis with some nodules were intact or only patchy necrosis of the parenchyma, disparity of extent and stage of necrosis existed in slides, which were the major difference in histopathological change in HBC and CHB group.</p><p><b>CONCLUSION</b>Most of CSHB cases were based on liver cirrhosis, which match with the international definition of ACLF, while small part of CSHB cases based on HBC and CHB are identical to acute/subacute liver failure.</p>

ABSTRACT

<p><b>BACKGROUND</b>Bulbous nasal tips and lower dorsa are common facial features in Chinese people, and surgery to reshape these is frequently requested. The use of silicone implants in rhinoplasty has been widely used in China for many years, but is not suitable for patients seeking Caucasian tip shapes. The creation of an excessively high tip supported only by a silicone implant inevitably leads to implant extrusion. Although many rhinoplasty techniques have been used in Caucasian patients, there is currently no suitable method for Chinese patients, whose anatomy differs from that of Caucasians. The present study was aimed to investigate the clinical outcome of a novel method of rhinoplasty in Chinese people.</p><p><b>METHODS</b>Eighty patients underwent rhinoplasty using our method between 2002 and 2006. We classified the patients into three types, according to the distance between tip defining points, and used different techniques accordingly. Furthermore, an innovative cartilage carving method and a tip fibro-fatty tissue flap were designed and combined with traditional techniques, such as insertion of silicone implant, cartilage grafts, suture techniques and cephalic trimming to reshape the nasal contours. The followup period was 10 - 60 months (average, 21 months).</p><p><b>RESULTS</b>Remarkable modifications in nasal contours were achieved. No complications developed in any of the 80 patients. Seventy-eight patients were satisfied with the results. The outcomes remained unchanged over time.</p><p><b>CONCLUSION</b>Our method is effective and suitable for the treatment of Chinese patients with lower dorsa and bulbous nasal tips.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To discuss the diagnostic value of an ultrasonic assessing system for detecting the severity of hepatic fibrosis in patients with chronic hepatitis B (CHB).</p><p><b>METHODS</b>Ultrasonographic variables were analyzed in 110 CHB patients. An ultrasonic semi-quantitative scoring system using seven ultrasonic morphologic parameters, a Fisher discriminating function and three quantitative ultrasonic parameters was developed. The performance of these methods was also studied and compared.</p><p><b>RESULTS</b>The areas under the curve of the scoring system for different liver fibrosis stages were >or= S2: 0.946, >or= S3: 0.914, and S4: 0.915. The total score was well correlated with the histological stage of fibrosis (r=0.824, P < 0.001). There was a significant difference between the stages of fibrosis. The accuracy of the Fisher discriminating function for identifying three study endpoints was 76.5%, 78.2% and 67.3%. Combining the ultrasonic scoring system and the discriminating function, the specificity was 85%-90% and the accuracy was 77%-84%.</p><p><b>CONCLUSION</b>Our ultrasonic semi-quantitative scoring system is a noninvasive method for quantitating liver fibrosis. If it is used together with a discriminating function, the accuracy of diagnosing liver fibrosis can be significantly increased.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the histopathological features in livers of chronic severe hepatitis B (CSHB) patients.</p><p><b>METHODS</b>Histology of 42 livers was studied. HE, Masson, Sweet and D-PAS staining and cytokeratin 7, CD68 and proliferating cell nuclear antigen immuno-histochemical staining were used in the study.</p><p><b>RESULTS</b>In CSHB, the livers showed massive or submassive necrosis in a background of other histological changes of chronic hepatitis B. The characteristic pictures of these livers were necrosis of all the hepatocytes in some nodules, while in other nodules there were only patchy necroses of the parenchyma. In some other nodules the necrotic hepatocytes were all removed and only the scaffolding stroma remained. Meanwhile, regeneration of hepatocytes and bile ductules were also seen.</p><p><b>CONCLUSIONS</b>The liver histopathological changes in CSHB are identical, but not of the same degree as those of acute severe and subacute severe hepatitis B. In making differential diagnoses for liver aspiration biopsies of these patients, this fact should be kept in mind.</p>

ABSTRACT

<p><b>OBJECTIVES</b>To analyze the frequency and the clinical and virological features of HBeAg-negative and HBeAg-positive chronic hepatitis B.</p><p><b>METHODS</b>Four hundred and seventeen chronic hepatitis B patients, 286 males and 131 females seen in our center were studied. Liver biopsies were taken from 83 patients.</p><p><b>RESULTS</b>The cases with HBeAg-negative chronic hepatitis B were 241 (57.8%), with an average age of 43.7+/-10.8 and a history of 16.8+/-8.5 years. HBeAg-positive chronic hepatitis B cases were 176 (42.2%), with an average age of 36.95+/-11 and a history of 12.3+/-8.0 years. HBeAg-negative patients were significantly older (P < 0.01) in age and had a longer disease history. ALT levels and the percentage of HBV DNA were higher than 10(5) copies/ml in HBeAg-negative patients and were significantly lower than those in the HBeAg-positive patients [(37.66+/-32.93) U/L vs. (82.09+/-107.57) U/L, 38.2% vs. 94.3%, P < 0.01]. Liver biopsies from 47 HBeAg-negative patients showed that the number of cases with inflammation scores of G1, G2, G3 and G4 were 5, 27, 14, 1 and the number of cases with fibrosis scores of S1, S2, S3 and S4 were 10, 12, 5, 20, respectively. In the 36 HBeAg-negative patients the respective number of cases with inflammation scores of G1, G2, G3 and G4 were 5, 14, 15, 2, and with fibrosis scores of S1, S2, S3, S4 were 8, 12, 6, 10. Although histopathological inflammation and fibrosis scores had no statistical difference between HBeAg-negative and positive patients (P > 0.05), 53.2% patients of HBeAg-negative group and 44.5% patients of HBeAg-positive group had a fibrosis score of >or= S3.</p><p><b>CONCLUSION</b>Despite lower serum ALT and HBV DNA, HBeAg-negative chronic hepatitis B still has a significant disease progression. This observation may help to develop better clinical management in HBeAg-negative chronic hepatitis B patients.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To study the correlations between clinical features and liver pathohistological changes of chronic hepatitis B virus (HBV) carriers and to discuss the factors which may influence the prognosis.</p><p><b>METHODS</b>Ninety HBV carriers who had liver biopsies were enrolled in this study.</p><p><b>RESULTS</b>(1) The mean follow-up period of the patients was 118 weeks. (2) Fifty-four patients (60.0%) had G1 hepatitis and 21 (23.3%) had G2 hepatitis. The fibrosis stages were graded as S1(42) and S2(21). (3) There were significant age differences among S0, S1 and S2. (4) There were significant differences in aminotransferase levels between patients who had a normal liver histology and those who had mild hepatitis. (5) The grades of liver inflammation were not correlated with the titers of HBeAg and HBV DNA in sera. The stages of liver fibrosis were not correlated with the titers of HBVDNA in sera. Most of the HBeAg negative patients progressed to S2. (6) There were significant differences in spleen dimensions measured by ultrasonography between S0, S1 and S2 patients. (7) During the follow-up period serum aminotransferase (ALT) levels remained normal in 60 patients (group A); 22 patients had transient elevations (group B), and 8 patients had persistent increases (group C). There were significant differences of the ratios of S0 and S2 cases among patients in groups A, B and C. (8) Age and fibrosis stages were predictive factors of liver cirrhosis.</p><p><b>CONCLUSIONS</b>Most chronic HBV carriers had mild inflammatory histological changes in their livers and also had different degrees of liver fibrosis. This follow-up study shows that some of those carriers should have had antiviral therapy.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To establish a practical and reproducible animal model of human acute-on-chronic liver failure for further study of the pathophysiological mechanism of acute-on-chronic liver failure and for drug screening and evaluation in its treatment.</p><p><b>METHODS</b>Immunological hepatic fibrosis was induced by human serum albumin in Wistar rats. In rats with early-stage cirrhosis (fibrosis stage IV), D-galactosamine and lipopolysaccharide were administered. Mortality and survival time were recorded in 20 rats. Ten rats were sacrificed at 4, 8, and 12 hours. Liver function tests and plasma cytokine levels were measured after D-galactosamine/lipopolysaccharide administration and liver pathology was studied. Cell apoptosis was detected by terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling assay.</p><p><b>RESULTS</b>Most of the rats treated with human albumin developed cirrhosis and fibrosis, and 90% of them died from acute liver failure after administration of D-galactosamine/lipopolysaccharide, with a mean survival time of (16.1+/-3.7) hours. Liver histopathology showed massive or submassive necrosis of the regenerated nodules, while fibrosis septa were intact. Liver function tests were compatible with massive necrosis of hepatocytes. Plasma level of TNFalpha increased significantly, parallel with the degree of the hepatocytes apoptosis. Plasma IL-10 levels increased similarly as seen in patients with acute-on-chronic liver failure.</p><p><b>CONCLUSION</b>We established an animal model of acute-on-chronic liver failure by treating rats with human serum albumin and later with D-galactosamine and lipopolysaccharide. TNFalpha-mediated liver cell apoptoses plays a very important role in the pathogenesis of acute liver failure.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the malignant tendency of liver basophilic cells in rats by examining the liver dynamic pathological changes during the hepatocarcinogenesis induced by diethylnitrosamine (DEN).</p><p><b>METHODS</b>One hundred forty male Sprague-Dawley rats, about 200 g each, were randomly divided into a normal group and a model group. The model group rats were administered 1% DEN intragastrically once a week for 14 weeks. The normal control group rats were given saline instead of DEN. Seven to ten rats of the model group were sacrificed at 2, 3, 5, 8, 10, 12, 14, 18 weeks. The remaining rats were followed to the end of the experiment at 26 weeks. Histopathological changes of the livers were analyzed, and the localization of GST-P and PCNA in the livers were detected in situ by immunohistochemistry.</p><p><b>RESULTS</b>According to the characteristics of the lesions in the model group, histological liver change patterns were categorized into three phases: (1) liver injury phase (2 to 5 weeks) with centrilobular necrosis, a small amount of collagen deposition in the necrotic regions with fibrous septa development and cell proliferation; (2) the cirrhosis phase (8 to 12 weeks) with significant hepatocellular regeneration and collagen deposition. As the regenerative nodules and fibrous septa formed, cirrhosis with uniform sized nodules developed in all the rats at 12 weeks. In the regenerative nodules, significant hepatocellular metamorphosis was seen; (3) In the carcinomatous transformation and nodular remodeling phase (after 14 weeks), two types of cancer, namely hepatocellular carcinoma and cholangiocarcinoma were found. Incidence of the cancer was 62.5% at 18 weeks. Basophilic cell lesions appeared beginning at 10 weeks. Pale bodies were seen in some basophilic cells. Small cell changes appeared starting at 12 weeks. Some of these cells containing droplets like lipid vacuoles, invaded into the surrounding liver tissues. Both basophilic cell lesions and small cell changes were all positive for proliferating cell nuclear antigen (PCNA).</p><p><b>CONCLUSION</b>Development of foci of basophilic small cells, with cells containing lipid vacuoles and pale bodies, and invading into the surrounding liver tissues are the changes highly suggestive of an early hepatocellular carcinoma transformation.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To develop a diagnostic model comprising clinical and serum markers for assessing HBV-related liver fibrosis.</p><p><b>METHODS</b>270 chronic hepatitis B patients were randomly allocated to either an estimation group (195 cases) or a validation group (75 cases). Liver biopsies were done and staging of fibrosis was assessed. Twenty-six common clinical and serum markers were analyzed initially in the estimation group to derive a predictive model to discriminate the stages of fibrosis. The model created was then assessed with ROC analysis. It was also applied to the validation group to test its accuracy.</p><p><b>RESULTS</b>Among 13 variables associated with liver fibrosis selected by univariate analysis, age, gamma glutamyltranspeptidase (GGT), hyaluronic acid (HA), and platelet count (PLT) were identified by multivariate logistic regression analysis as independent factors of fibrosis. A fibrosis index constructed from the above four markers was established. In ROC analysis, the AUC was 0.889 for the estimation group and 0.850 for the validation group for discriminating > or =S3 from < or=S2. Using the optimal cutoff score 3.0, the sensitivity of the index was 90.2%, the specificity 76.1%, and the accuracy was 82%. There was a positive linear relationship between the index scores and the fibrosis stages (r = 0.731, P<0.001). The AUC for identifying > or=S2 was 0.873 with sensitivity/specificity of 79%/82%, cutoff score 2.2; The AUC for identifying S4 was 0.872 with sensitivity/specificity of 83%/75%, cutoff score 5.4. There were no significant differences in diagnostic efficacy in the model between the estimation and the validation group (P>0.05).</p><p><b>CONCLUSION</b>A model for assessment of liver fibrosis was established with easily accessible markers. It appears to be sensitive, accurate and reproducible, suggesting it could be used to assist or replace liver biopsy to detect dynamic changes of HBV-related liver fibrosis.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the relationship of serum metalloproteinase with the severity of liver fibrosis and inflammation.</p><p><b>METHODS</b>A total of 88 patients with HBV-related liver fibrosis and early cirrhosis were enrolled from six hospitals. Serum fibrosis markers including hyaluronic acid (HA), IV collagen (IV-C), aminoterminal propeptide of type III procollagen (PIIIP), laminin (LN), matrix metalloproteinases (MMP) 1, 2, 9 and tissue inhibitors of metalloproteinase (TIMP) 1, 2 levels were determined. Liver biopsies were assessed according to a modified Scheuer and Chevallier's scoring system.</p><p><b>RESULTS</b>Serum TIMP1 (r=0.540) and MMP2 (r=0.314) were correlated positively with the degree of hepatic fibrosis, whereas serum MMP1 (r=-0.495) was correlated negatively. By receiver operating curve analysis (ROC), the sensitivity to distinguish the fibrosis stage 2 from stage 1 was 90.5% and the specificity was 52.0% if the cut-off value of MMP1 was 13.96 ng/ml, and the sensitivity was 91.6% and the specificity was 64.0% if the cut-off value of TIMP1 was 76.84 ng/ml. The sensitivity to distinguish cirrhosis (stage 4) from fibrosis (stage 3) was 70.7% and specificity was 80.9% if the cut-off value of MMP1 was 6.86 ng/ml, and the sensitivity was 60.5% and the specificity was 92.3% if the cut-off value of TIMP1 was 210.04 ng/ml.</p><p><b>CONCLUSION</b>Serum TIMP1, MMP1, MMP2 levels and TIMP1/MMP1 ratio could be used as serum fibrosis markers.</p>

ABSTRACT

<p><b>OBJECTIVES</b>To further assess the clinical antifibrotic efficacy of Cpd 861 on chronic hepatitis B related fibrosis and early cirrhosis using a randomized, double blind, and placebo controlled clinical trial.</p><p><b>METHODS</b>Total 136 patients with HBV-related fibrosis and early cirrhosis were allocated randomly into Cpd 861 treatment group and placebo group for 24 weeks treatment. Serum fibrosis markers including hyaluronic acid (HA), IV collagen (IV-C), amino terminal propeptide of type III procollagen (PIIIP), and laminin (LN) and serum MMP1, 2, 9, TIMP1, 2 level were determined before and after 24 weeks treatment. Liver biopsies before and after 24 weeks of treatment were assessed according to modified Scheuer and Chevallier's scoring system.</p><p><b>RESULTS</b>Total 52 patients in Cpd 861 treatment group and 50 patients in placebo-controlled group completed the 6 months. ALT level decreased from 68.2 U/L+/-68.6 U/L to 45.9 U/L+/-26.1 U/L, AST level decreased from 60.4 U/L+/-62.6 U/L to 46.7 U/L+/-39.0 U/L (P < 0.05) after 24 weeks treatment, whereas there was no significant change in placebo group (ALT: 65.3 U/L+/-48.3 U/L to 85.4 U/L+/-115.5 U/L; AST: 60.4 U/L+/-44.6 U/L to 77.6 U/L+/-89.6 U/L, P > 0.05). Serum fibrosis markers, including HA, IV-C, PIIIP, and LN were decreased after treatment, but there is no statistically significant compared with placebo group. Compared with placebo group, serum TIMP1 and MMP9 level decreased significantly (TIMP1 172.0 ng/ml+/-79.6 ng/ml vs 133.5 ng/ml+/-66.8 ng/ml; MMP9 116.1 ng/ml+/-88.2 ng/ml vs 80.4 ng/ml+/-79.0 ng/ml), and the ratio of TIMP1/MMP1 (48.3+/-96.3 vs 19.9+/-28.0) were also decreased after 861 treatment. In patients treated with Cpd 861, hepatic inflammatory score (from 14.0+/-6.0 to 10.2+/-6.1), fibrosis score (from 11.9+/-6.5 to 8.2+/-4.5), and relative content of collagen (from 18.9%+/-9.5% to 14.9%+/-8.4%) decreased significantly. In contrast, there was no significant change in placebo group. The reversal (fibrosis score decrease > or = 2) rate of fibrosis in Cpd 861 group was 38.9% in S2, 53.3% in S3 (precirrhotic) and 78.6% in S4 (cirrhosis), significantly higher than those in placebo group (14.3%, 25.0%, and 41.7%, respectively). The overall reversal rate was 52.0% in Cpd 861 group, and 20.0% in placebo group (P < 0.05). No serious adverse effects were observed during Cpd 861 treatment.</p><p><b>CONCLUSION</b>Liver fibrosis and early cirrhosis due to HBV infection in man could be definitely reversed by herbal remedy Cpd 861.</p>

ABSTRACT

Objective The aim of our study is to establish and characterize the animal model for au- toimmune myositis.Methods Fifty male SD rats were randomly divided into 2 groups:model group(n=40) and control group(n=10).The model group rats were immunized with muscle homogenate every week for 5 weeks and received an injection of 2?g pertussis toxin at the first and second week.As controls,10 SD rats were injected with an equal volume of normal saline.Tissue specimens from limb skeletal muscles were ob- tained at 1,2,3,4,5 weeks after injection.At the same time,the blood samples were collected,and the level of CPK was measured.Results The model group had significantly elevated serum CPK levels.There were multiple inflammatory lesions in the skeletal muscles.Local degeneration and necrosis of muscle fibers with disappeared transverse striation,mononuelear cell infiltration in the interstitial could be observed.The patho- logic grade was mainly 2a.The infiltrating mononuclear cells were predominantly CD8~+T cells that mainly lo- cated in the endnmysium.MHC classⅠantigen expression on muscle fiber membranes in the model group was upregulated.Conclusion The experimental autoimmune myositis induced by syngeneic skeletal muscle ho- mogenate in SD rat is pathologically similar to human myositis.It can be used as a good model for human myositis and provides the basis for the etiopathology and therapeutical studies.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the clinical usefulness of noninvasive diagnostic methods in evaluating liver fibrosis in hepatitis B virus (HBV) patients.</p><p><b>METHODS</b>102 patients with chronic hepatitis B (CHB) were enrolled from Beijing Friendship Hospital Affiliated to Capital University of Medical Sciences. Noninvasive diagnostic methods including ultrasonography, CT, serum markers of liver function and fibrosis, and HBV DNA were performed and compared with histological fibrotic changes in order to establish a noninvasive method for detecting the degree of liver fibrosis.</p><p><b>RESULTS</b>The total score of liver surface, edge, parenchyma echogenicity, intrahepatic vessels, and the size of spleen had a coefficient of 0.822 with fibrotic stage. By receiver operating curve (ROC) analysis, the sensitivity to distinguish cirrhosis from CHB was 86.1% and the specificity was 95.5% if the total ultrasonic score was more than 10. The CT imaging diagnosed liver cirrhosis with a specificity of 100% and a sensitivity of 48.5%. The change of CT values in cirrhotic patients was lower than that in controls and no cirrhotic patients (F=5.805, P<0.01), when the voltage was increased from 100 KV to 140 KV. Except normal controls and S1 group, S2 and S3 group, the level of HA and collagen IV between the other groups were statistically different. The cut-off value of HA to diagnose cirrhosis was 108 (microg/L) with a sensitivity of 72.2% and a specificity of 80.3%. The cut-off value of collagen IV to diagnose cirrhosis was 188 (microg/L) with a sensitivity of 72.2% and a specificity of 78.8%. When ultrasonography was combined with serum markers, the sensitivity was 72.2% and the specificity was 80.3%.</p><p><b>CONCLUSION</b>Both ultrasonography and serum markers are useful to diagnose cirrhosis. The combination of the two examinations is more valuable than any one alone. The characteristic CT imaging has high specificity but low sensitivity in diagnosing early cirrhosis. HA and collagen IV are correlated more closely with the stage of fibrosis, and can reflect the severity of fibrosis.</p>
