Objective Based on the liver biopsy samples in the past 10 years, this study aimed to investigate the incidence of fatty liver, the relationship among fatty liver and other underlying liver diseases, the clinical and pathological characteristics and the risk factors of fatty liver. Methods In the total 658 cases of liver biopsy from 1988 to 1997, there were 71 cases of fatty liver, among them 68 cases were nonalcoholic fatty liver. Matched by sex and age, 155 cases of non fatty liver cases were taken as control. All cases had had the tests of liver function, blood lipid profile, blood glucose and hepatitis virus markers. Liver biopsy samples were investigated by pathologists. Results The incidence of fatty liver among all the liver biopsy cases was 10.8%. The patients' ALT, AST, TB and CB levels in fatty liver group were significantly lower than in non fatty liver group ( P

PurposeTo establish sensitive and reliable serum marker on liver fibrosis for early clinical diagnosis. MethodsSerum hyaluronate acid,type Ⅲ procollagen and type Ⅳ procogen of 48 patients with viral hepatitis were analyzed by radioimmunoassay and ELISA respectively. ResultsThe serum HA, PCⅢ and PCⅣ level increased gradually with the progress of the disease. Their levels were correlated distinctly with the index of hepatic activity of inflammation and that of fibrosis.ConclusionsThe value of serum HA,PCⅢ and PCⅣ in predicting liver fibrosis will be enhanced ff the effect of inflammation could be excluded.

Objective To study protein variation between PtenL/LMEFs and Pten△/△MEFs cells.Methods Two-dimensional electrophoresis(2-DE) was employed to compare the differential expression proteins between PtenL/LMEFs and Pten△/△MEFs cells.Six differential expression proteins were digested in gel by enzyme and the mass of generated peptides was measured by matrix assisted laser desorption ionization time of flight mass spectrometry(MALDI-TOF-MS).The data obtained from peptide mass fingerprinting(PMF) were searched using the Internet available database and five proteins were identified.Results Compared with that of PtenL/LMEFs,expression level of proteins including phosphoglycerate mutase 1(PGAM1) and peptidyl-prolyl cis-trans isomerase C(PPIC) was up-regulated,whereas expression level of Transgelin 2 was down-regulated in Pten△/△MEFs cells.B and F proteins were both identified to be peroxiredoxin-6.They had similar molecular weight but different PI which might be caused by post-translation modification.B protein was only expressed in Pten△/△MEFs cells.Conclusion The protein profile of Pten△/△MEFs cells displayed obvious difference compared to that of PtenL/LMEFs cells.The results implied that various distinct different proteins might lead to cancer.

Clinical features and related information on diagnosis and treatment of 45 cases of Castleman's disease (CD) were retrospectively analyzed.Based on the clinical classification, localized CD (LCD) was found in 26 cases, multicentric CD (MCD) was found in 19 cases.Most cases of LCD presented the symptoms of compression, while MCD had complicated and non-specific clinical manifestations, making the early diagnosis more difficult.All 26 cases with LCD underwent surgery, among which only 2 cases relapsed.Sixteen out of 19 patients with MCD were treated with glucocorticoids or combined chemotherapy, and 14 cases achieved complete or partial remission.The results show that patients with CD have variant manifestation and the diagnosis depend on CT scan or histopathology examination.Most LCD can be cured by complete surgical resection, and MCD can achieve remission by the treatment with glucocorticoids or combined chemotherapy.

Objective To identify the changes of DNA methylation profile in the process of malignant transformation of BEP2D cell induced by α particles.Methods The genomic DNAs were isolated from the malignant transformation BERP35T4 cells and immortalized human bronchial epithelial cell line BEP2D.Genomic DNAs were digested by MseI and ligated of PCR linkers.Methylated DNAs were digested by BstUI and amplified by PCR.The methylated DNA probes were prepared by labeling with Cy3 and Cy5 fluorescence dyes individually and hybridized to the methylation CpG-Island microarray.The hybridization results were scanned and analyzed.Intensity values were quality controlled and normalized.The normalized data were used to identify the differentially expressed genes based on a 1.5 fold difference of the expression level.Results There were 16 genes which showed changes of methylation level in malignant transformation BERP35T4 cells, 9 of them were hypermethylation and 7 were hypomethylation.These genes were including the SKIP gene, PPP3CC gene, MAP2K6 gene, KIR2DL1 gene, KIR2DL4 gene, KIR3DP1 gene, ZNF493 gene, ZNF100 gene, NKX2-5 gene, TFAP2D gene, DR1 gene, KCNJ16 gene, CCDC18 gene, FNBP1L gene, IRX4 gene, EPB41L3 gene, TCP10 gene and so on.Conclusions The DNA methylation might have effects on ionizing radiation drived tumorigenesis.

OBJECTIVE: To study the efficacy and safety of Fuzheng Huayu Capsule (FZHY Capsule) against liver fibrosis with chronic hepatitis B. METHODS: Multicentric, randomized, double blinded and paralleled control led trial was conducted on patients (aged between 18 and 65) with liver fibrosis in chronic hepatitis B Indexes observed: (1) hepatic histological changes and HBV markers were observed at 0 and 24th week during the treatment; serological indexes (HA, LN, P-III-P, IV-C) were determined and B ultrasound examination of spleen and liver was taken at 0, 12th, 24th week; liver function (during the period of follow-up, liver function and serological indexes for liver fibrosis were evaluated) were observed at 0, 6th, 12th, 18th, 24th week; (2) indexes for safety: blood and urine routine tests, renal function and ECG were examined. RESULTS: (1) Enrollment and demographic data: There was no significant difference between the trial (110 cases) and control group (106 cases) in demographic feature, vital signs, course of illness, history for drug anaphylaxis, history of previous therapy, liver function, serological indexes for liver fibrosis, liver histological examination (99 cases for test group, 96 cases for control group), HBV markers, and renal function, etc. (2) Histological pathological examination: 93 cases of liver histological examination were taken, of these 50 cases for the trial group and 43 cases for control group which turned out to be at S mean value of 2.33 and 2.11 respectively pretreatment according to criteria for liver fibrosis staging. Post-treatment, the trial showed a significant decrease with S value of 1.80 compared to that of pretreatment; however, there was no significant improvement in control group before and after the treatment with S mean value of 2.14. There was significant difference in reversing rate (decrease at least 1 stage according to criteria for liver fibrosis staging) between the trial (52%) and control (23.3%) after liver biopsy. The trial had a rather good effect on improving inflammatory activity and was superior to control group with a marked decrease of mean value of inflammatory activity and score of inflammation (P<0.05). (3)Serological indexes for liver fibrosis: There was a significant decrease in HA, LN, P-III-P, IV-C content in test group after 12 and 24 weeks' treatment compared to that of pretreatment; the differences of HA, LN, P-III-P, IV-C between 12, 24 weeks' treatment and pretreatment were significantly greater than control group (P<0.01 or 0.05); the effectual was defined as 2 of 4 indexes lowered more than 30% of the baseline, according to this criteria, the trial was 72.7%, while control group 27.4% (P<0.01). (4)Liver function: Obvious improvement of serum Alb, ALT, AST, GGT was seen in 2 groups; compared with control group, marked improvement of GGT and Alb in the trial (P<0.05); the effective rate of serum ALT in the trial group was 72.7%, while control 59.4%. (5)No changes of significant difference between pre- and post-treatment in routine tests for blood and urine, renal function and ECG, etc. There was also no difference in the stable rate of ALT and serological indexes for liver fibrosis between the trial and control group 12 weeks after withdrawal (P<0.05). CONCLUSION: Fuzheng Huayu Capsule has good effect on alleviating liver fibrosis in chronic hepatitis B without any adverse effect and is superior to Heluo Shugan Capsule. Fuzheng Huayu Capsule is a safe and effective medicine for the treatment of liver fibrosis in chronic hepatitis B.
