OBJECTIVETo study the clinical features of patients with primary biliary cirrhosis (PBC) in order to improve the doctors' awareness of the disease.
METHODSGeneral status, clinical manifestations and laboratory findings of 40 patients with PBC were reviewed.Thirty-seven patients were females (37/40), and the mean age at diagnosis was 50.5 +/- 7.8 years. The time interval from initial symptoms or preliminary diagnosis to final diagnosis was 24.0 +/- 23.6 months.
RESULTSThe most frequently reported symptoms were fatigue (67.5%, 27/40), jaundice (60%, 24/40) and pruritus (32.5%, 17/40). Eight patients (20%) had associated auto-immune diseases (Sjogren's syndrome and/or rheumatoid a(c)arthritis). Serum alkaline phosphatase (ALP) and gamma glutamyl transpeptidase (gamma-GT) levels were markedly elevated (520.3 +/- 382.3 IU/L and 648.6 +/- 529.1 IU/L, respectively) in all patients, while alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels were mildly elevated (82.6 +/- 54.5 IU/L and 100.7 +/- 47.2 IU/L, respectively). Twenty-four patients (60%) had a total bilirubin level >/= 34.2 micromol/L. Thirty-five patients (87.5%) had elevated serum immunoglobin M,and 97.5% of patients (39/40 ) were anti-mitochondrial antibody (AMA)/AMA-M2 positive.
CONCLUSIONElevated serum ALP and gamma-GT levels, together with a positive AMA/AMA-M2, can help the diagnosis of PBC. Liver biopsy is useful to confirm the diagnosis and to differentiate histopathological stages.

OBJECTIVETo investigate the effects of herbal compound 861 (Cpd861) on hepatocarcinogenesis induced by diethylntrosamine and 2-acetylaminofluorene (DEN-AAF) in female Sprague Dawley rats.
METHODSLiver preneoplastic foci were induced using the DEN-AAF method in female Sprague Dawley rats, which were then treated with Cpd861. For quantitative assessment of liver preneoplastic foci, the placental form of glutathione-S-transferase (GST-P) positive foci were measured using immunohistochemical staining and image analysis. GST-P protein expression was measured by Western blotting, mRNA expression was assessed by Northern blotting.
RESULTSTreatment using DEN-AAF caused a significant decrease in body weight and increase in liver weight compared to the control group. Oral Cpd861 administration essentially prevented DEN-AAF-induced body weight loss and liver weight increase. When 2-AAF was followed by treatment with Cpd861, there was a decrease in the number of large foci as compared to 2-AAF alone. However, there were still considerable numbers of small mixed clear/vacuolated cell foci, some of which were positive for GST-P. Significant increase in GST-P protein and mRNA expression were observed in the DEN-AAF group, while treatment with Cpd861 inhibited the increase. The effect of Cpd861 on hepatocarcinogenesis occurred in a concentration-dependent manner.
CONCLUSIONChinese herbal compound Cpd861 prevents hepatocarcinogenesis in DEN-AAF-induced liver preneoplastic lesions in rats.

OBJECTIVEProtein induced by vitamin K absence or antagonist II (PIVKA II), also called des-gamma carboxy prothrombin (DCP), is a sensitive marker for the diagnosis of hepatocellular carcinoma (HCC), in Japan and the United States since the sensitive kits were available (1998). PIVKA II is not used in clinical diagnosis in China so far. The aim of this study was to assess the diagnostic value of PIVKA II in Chinese patients with HCC.
METHODSSerum PIVKA II and alpha-fetoprotein (AFP) levels were determined in 60 patients with HCC and 30 patients with cirrhosis not carrying HCC.
RESULTSThe mean serum concentration of PIVKA II in HCC patients (784.3 +/- 1364.1 mean +/- s) was higher than that in cirrhosis patients (16.1 +/- 31.7); this difference was highly significant (P < 0.0001). When the cutoff level of 40 mAU/ml was used as the level of discriminating HCC from cirrhosis, 51.7% of patients (31/60) with HCC had PIVKA II values above this level (sensitivity). Only 4 patients with cirrhosis had such high PIVKA II levels. Thus, the specificity of this test was 86.7% (26/30). Total accuracy was 62.2% [(31 + 26)/(60 + 30)]. Seven of 19 small HCCs (36.84%) had PIVKA II values above the cutoff level. Concentrations of AFP above 20 ng/ml were observed in 34 of 60 patients with HCC (56.7%) and in 11 patients with cirrhosis (36.7%). Eleven of 26 patients with HCC (46.2%) without increased AFP had concentrations of PIVKA II greater than 40 mAU/ml. No significant correlation was found between serum levels of AFP and PIVKA II that were measured in 60 HCC patients (rs = 0.101, P = 0.247). Combining the information from PIVKA II and AFP showed an increase of approximately 21.6% over AFP and 26.7% over PIVKA II alone. For small HCC patients, combining the information from PIVKA II and AFP showed an increase of approximately 15.8% over AFP alone and 21.1% over PIVKA II alone.
CONCLUSIONPIVKA II is a useful early diagnostic marker for HCC and may be more sensitive when combined with AFP in Chinese patients.

Objective:To study the treatment outcomes of transjugular intrahepatic portal shunt (TIPS) on refractory hepatic sinus obstruction syndrome (HSOS) caused by Gynura segetum.Methods:The clinical data of 15 patients with refractory HSOS caused by Gynura segetum treated at the Department of Vascular Surgery, Henan Provincial People's Hospital from January 2017 to April 2021 were retrospectively analyzed. There were 7 males and 8 females, with ages ranging from 30 to 85 years, mean ± s. d. (61.2±14.1) years. Albumin, alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, glutamyl transferase, and portal vein pressure were compared before and after TIPS. The liver function and renal function of these patients were followed up.Results:When compared with pre-operation, the albumin, alanine aminotransferase, aspartate aminotransferase and other indexes were significantly improved after TIPS (all P<0.05). The portal vein pressure of 15 patients significantly decreased from the preoperative volume of (41.7±3.5) cmH 2O (1 cmH 2O=0.098 kPa) to (28.3±4.4) cmH 2O ( t=10.41, P<0.001). The preoperative liver function was Child-Pugh grade A in 1 patient, grade B in 8 patients, grade C in 6 patients. The postoperative Child-Pugh grading was grade A in 14 patients and grade B in 1 patient. Ascites, gastrointestinal bleeding, abdominal pain, abdominal distention and spontaneous peritonitis all disappeared in these 15 patients. Postoperative hepatic encephalopathy developed in 2 patients and hepatic myelopathy in 1 patient. Conclusion:TIPS for treatment of HSOS caused by Gynura segetum resulted in a rapid recovery of liver function, rapid symptomatic relief, with a low incidence of hepatic encephalopathy/hepatic myelopathy.

BACKGROUND:
Hypertrophic cardiomyopathy (HCM) is an underdiagnosed genetic heart disease worldwide. The management and prognosis of obstructive HCM (HOCM) and non-obstructive HCM (HNCM) are quite different, but it also remains challenging to discriminate these two subtypes. HCM is characterized by dysmetabolism, and myocardial amino acid (AA) metabolism is robustly changed. The present study aimed to delineate plasma AA and derivatives profiles, and identify potential biomarkers for HCM.
METHODS:
Plasma samples from 166 participants, including 57 cases of HOCM, 52 cases of HNCM, and 57 normal controls (NCs), who first visited the International Cooperation Center for HCM, Xijing Hospital between December 2019 and September 2020, were collected and analyzed by high-performance liquid chromatography-mass spectrometry based on targeted AA metabolomics. Three separate classification algorithms, including random forest, support vector machine, and logistic regression, were applied for the identification of specific AA and derivatives compositions for HCM and the development of screening models to discriminate HCM from NC as well as HOCM from HNCM.
RESULTS:
The univariate analysis showed that the serine, glycine, proline, citrulline, glutamine, cystine, creatinine, cysteine, choline, and aminoadipic acid levels in the HCM group were significantly different from those in the NC group. Four AAs and derivatives (Panel A; proline, glycine, cysteine, and choline) were screened out by multiple feature selection algorithms for discriminating HCM patients from NCs. The receiver operating characteristic (ROC) analysis in Panel A yielded an area under the ROC curve (AUC) of 0.83 (0.75-0.91) in the training set and 0.79 (0.65-0.94) in the validation set. Moreover, among 10 AAs and derivatives (arginine, phenylalanine, tyrosine, proline, alanine, asparagine, creatine, tryptophan, ornithine, and choline) with statistical significance between HOCM and HNCM, 3 AAs (Panel B; arginine, proline, and ornithine) were selected to differentiate the two subgroups. The AUC values in the training and validation sets for Panel B were 0.83 (0.74-0.93) and 0.82 (0.66-0.98), respectively.
CONCLUSIONS
The plasma AA and derivatives profiles were distinct between the HCM and NC groups. Based on the differential profiles, the two established screening models have potential value in assisting HCM screening and identifying whether it is obstructive.
