San-Cao Granule () Ameliorates Hepatic Fibrosis through High Mobility Group Box-1 Protein/Smad Signaling Pathway / 中国结合医学杂志

<p><b>OBJECTIVE</b>To investigate the possible mechanism of San-Cao Granule (SCG, ) mediating antiliver fibrosis.</p><p><b>METHODS</b>A total of 60 male Sprague-Dawley rats were randomly divided into the normal control group, porcine serum-treated group, ursodesoxycholic acid (UDCA, 60 mg/kg), SCG (3.6 g/kg) group, SCG (1.8 g/kg) group and SCG (0.9 g/kg) group, with 10 rats in each group. Liver fibrosis was induced with porcine serum by intraperitoneal injection for 8 weeks, except for the normal control group. Then, the rats in the three SCG-treated groups and UDCA group were administered SCG and UDCA respectively for 4 weeks. The serum levels of alanine transaminase (ALT), aspartate transaminase (AST), albumin (ALB), total bilirubin (TBIL), hyaluronic acid (HA), laminin (LN), and type IV collagen (IVC) were examined using commercial kits and hepatic histopathology was examined with hematoxylin and eosin and Masson staining. Moreover, the protein expression levels of high mobility group box-1 protein (HMGB1), transforming growth factor β1 (TGF-β1), phosphorylated mothers against decapentaplegic homolog 3 (p-Smad3), Smad7, toll-like receptor 4 (TLR4), myeloid differentiation factor 88 (MyD88), nuclear factor-kappa B (NF-κB) and α-smooth muscle actin (α-SMA) were determined by western blot, immunohistochemistry and real time quantitative-reverse transcription polymerase.</p><p><b>RESULTS</b>Both SCG (3.6 and 1.8 g/kg) and UDCA significantly ameliorated the liver fibrosis induced by porcine serum as indicated by retarding the serum levels increasing of ALT, AST, TBIL, HA, LN and IVC and preventing the serum level reducing of ALB compared with the model group (all P<0.01). Meanwhile, the collagen deposition was attenuated by SCG and UDCA treatment. Furthermore, SCG markedly reduced the expressions of HMGB1, TGF-β1, p-Smad3, TLR4, MyD88, NF-κB and α-SMA, and enhanced the expression of the Smad7 compared with the model group (all P<0.01).</p><p><b>CONCLUSION</b>SCG ameliorates hepatic fibrosis possibly through inhibiting HMGB1, TLR4/NF-κB and TGF-β1/Smad signaling pathway.</p>

Clinical features of different clinical forms of childhood congenital hepatic fibrosis / 中国当代儿科杂志

<p><b>OBJECTIVE</b>To compare the clinical features of children with different clinical forms of congenital hepatic fibrosis (CHF), and provides a description of the characteristics of childhood CHF.</p><p><b>METHODS</b>Sixty children with CHF between January 2002 and June 2015 were enrolled, including 26 children with portal hypertensive CHF (PH CHF), 3 children with cholangitic CHF, 30 children with combined portal hypertensive and cholangitic CHF (mixed CHF), and 1 child with latent forms of CHF. The medical data of 26 children with PH CHF and 30 children with mixed CHF, including gender, age, clinical manifestations, physical signs, laboratory tests and imaging characteristics, were retrospectively studied.</p><p><b>RESULTS</b>Fever, jaundice and hepatomegaly were more frequently noted in children with mixed CHF than in those with PH CHF (P<0.05). Splenomegaly and liver cirrhosis occurred more often in children with CHF, but there was no significant difference in the incidences of splenomegaly and liver cirrhosis between the children with PH CHF and mixed CHF. The plasma prothrombin activity, white blood cell counts, platelet counts, mean platelet volume, serum levels of alanine transaminase, aspartate transaminase, alkaline phosphatase, γ-glutamyl transferase, leucine aminopeptidase, and total bile acids in children with mixed CHF were higher than in those with PH CHF (P<0.05). The decreased international normalized ratio and lower serum albumin levels were more frequently observed in children with mixed CHF than in those with PH CHF (P<0.05).</p><p><b>CONCLUSIONS</b>PH and mixed CHF are common forms in childhood CHF. The children with the two forms of PH usually manifest portal hypertension such as cirrhosis and hepatosplenomegaly. The liver damage may be common in children with mixed CHF.</p>

A clinical and pathological analysis of 22 cases of primary sclerosing cholangitis / 中华肝脏病杂志

<p><b>OBJECTIVE</b>To characterize the clinical, laboratory, imaging and pathological features of primary sclerosing cholangitis (PSC) and investigate the impact of ursodeoxycholic acid (UDCA) therapy on patient prognosis.</p><p><b>METHODS</b>The medical records of 22 patients diagnosed with PSC between 2002 and 2011 were retrospectively reviewed. The PSC diagnosis had been made in patients with suspect biochemical abnormalities following evaluation by magnetic resonance cholangiopancreatography (MRCP) and/or endoscopic retrograde cholangiopancreatography (ERCP) and percutaneous transhepatic cholangiography (PTC). Fibrosis and inflammation were assessed by immunohistochemical analyses of tissue biopsies. Outcome of patients treated with UDCA (13-15 mg/kg/day, oral) were compared to that of patients without UDCA treatment by the X2 or corrected X2 tests.</p><p><b>RESULTS</b>Among the 22 PSC patients, the majority was male (n=15) and presented with fatigue, dark urine, and body weight loss (n=15). Four cases had ulcerative colitis. At admission, all 22 cases showed elevated levels of alkaline phosphatase[ALP: (348+/-184) U/L], 19 cases showed elevated alanine aminotransferase [ALT: (94.0+/-67.0) U/L] and aspartate aminotransferase [AST: (98.0+/-67.0) U/L], and 15 cases showed elevated levels of total bilirubin (99.0+/-115.0) mumol/L and direct bilirubin (74.4+/-92.4 mumol/L. ERCP examination showed segmental intrahepatic bile duct stenosis with expansion, and stiff and enlarged gallbladder bile ducts, but unclear findings for the common bile ducts and pancreatic ducts. MRCP showed beading of the intrahepatic bile duct, stiffness of the bile duct wall, and dilation of the common bile duct. Fibrosis and inflammation were observed in the bile ducts, along with hyperplasia and the typical features of "onion skin" fibrosis and fibrous obliterative cholangitis. Five of the 10 patients treated with UDCA improved, and seven of the 12 patients in the non-UDCA treatment group improved. There was no statistically significant difference in outcome between the groups (paired X2=0.333, corrected X2=0.083, P more than 0.05).</p><p><b>CONCLUSION</b>PSC patients were predominantly male and the common clinical manifestations were fatigue, dark urine, and body weight loss. At admission, serum biochemical indicators of cholangitis were increased significantly and subsequent imaging studies confirmed the suspected diagnosis by showing obvious characteristic changes. UDCA treatment did not significantly improve patient prognosis.</p>

An analysis of the clinical characteristics of patients with chronic hepatitis B superinfected with acute hepatitis E / 中华实验和临床病毒学杂志

<p><b>OBJECTIVE</b>To investigate clinical features of the patients with hepatitis B superinfected with acute hepatitis E (AHE).</p><p><b>METHODS</b>Totally 625 consecutive patients enrolled from Dec 2002 to Dec 2006 were studied retrospectively. All of the patients were subclassified into acute hepatitis E group (AHE=437 cases) and Superinfected Group (S=188 cases), and S group was further divided into the group of chronic hepatitis B superinfected with acute hepatitis E (CHB+AHE, 130 cases) and the group of liver cirrhosis and hepatitis B superinfected with acute hepatitis E (LCB+AHE, 58 cases). In 32 of the 188 superinfected patients the effects of HEV on HBV were observed by comparing the levels of HBV DNA in acute vs. convalescence stages.</p><p><b>RESULTS</b>Compared with the patients with AHE, the superinfected patients had a higher level of total bilirubin (TBil), an elevated frequency of fulminate hepatitis, mortality and a longer period of the mean hospital stay for the cured patients but significantly lower levels of alanine aminotransferase (ALT), serum albumin and prothrombin activity (PA). Furthermore, the group of LCB+AHE had a higher level of TBil and higher incidences of complications such as ascites, peritonitis, hepatic encephalopathy and disturbance in glycometabolism than the group of CHB+AHE. The follow-up for the superinfected patients showed that 20 of 32 patients (62.5 percent) had decreased copies of HBV DNA during the recovery phase compared with the acute phase, and the mean decrease of HBV DNA was 2.1 log10. The HBV DNA was in a persistently undetectable level in 6 of 32 (18.8 percent) superinfected patients. However, 4 of 32 patients (12.5 percent) showed an unchanged levels of HBV DNA and 2 cases (6.2 percent) had a slightly increased HBV DNA levels.</p><p><b>CONCLUSION</b>Superinfection with AHE in patients with chronic hepatitis B leads to a more severe hepatic damage and the replication of HBV DNA can be transiently inhibited.</p>

Sequential analyses of circulating HBV specific T helper cell response in chronic hepatitis B patients receiving antiviral treatment / 中华实验和临床病毒学杂志

<p><b>BACKGROUND</b>To investigate the frequency of circulating HBV specific T helper cell and evaluate its association with serum levels of HBV DNA before and during lamivudine treatment in patients with chronic hepatitis B.</p><p><b>METHODS</b>The frequency of circulating HBV specific T helper cells in response to HBcAg in 25 chronic HBV-infected patients was determined by Elispot assay; serum HBV DNA was quantitated by real-time PCR.</p><p><b>RESULTS</b>The frequency of HBV specific T helper cell before antiviral treatment (47.30 +/- 25.50 SFCs /1 x 10(6) PBMC) was significantly higher than that at the third month of therapy (23.10 +/- 18.45 SFCs /1 x 10(6) PBMC, P < 0.05). All 8 patients observed dynamically had decreased frequency of HBV specific T helper cell at the third month of therapy; six patients with serum HBV DNA level reduced had higher frequency of HBV specific T helper cell before treatment than 2 patients without serum HBV DNA level decrease.</p><p><b>CONCLUSION</b>HBV specific T helper cell response at the time of hepatitis flare in chronic hepatitis B patients was significantly augmented compared to that at the time of catabasis.</p>

Clinical research on the effect of Oxymatrine on serum cholinesterase / 中华实验和临床病毒学杂志

<p><b>BACKGROUND</b>To investigate the effect of Oxymatrine (OM) on serum cholinesterase (ChE) during the treatment of viral hepatitis and the relationship between the change of ChE and the change of albumin (ALB), prothrombin activity (PTA) and other liver function tests.</p><p><b>METHODS</b>A total of 98 patients with viral hepatitis were divided into four groups. Group A consisted of 31 patients and were treated with OM intravenous infusion; Group B consisted of 30 patients, treated with OM orally; Group C consisted of 7 patients and were treated with OM intramuscular injection while Group D consisted of 30 patients, and were not treated with OM. ChE, ALB, PTA, liver function, renal function, soluble complement receptor-1 (sCR1) and erythrocyte innate immune adhesion function (EIIAF) were regularly determined.</p><p><b>RESULTS</b>ChE in Group A,B,C was dropped obviously during the treatment (P less than 0.001, less than 0.001, 0.023=. But there were no change in ALB, PTA, sCR1, EIIAF (P greater than 0.05), and remarkable improvement of ALT, AST, TBiL was seen during the treatment in Groups A, B, C. After the treatment with OM, the level of ChE recovered soon.</p><p><b>CONCLUSION</b>Serum level of ChE significantly declined during the treatment of viral hepatitis with OM, but no change was found in ALB, PTA, sCR1, EIIAF while liver function tests showed better results. So the drop of ChE does not mean deprivation of patient's liver disease.</p>
