ABSTRACT
Chronic HBV infection is an important phase in the natural history of HBV, but there are still controversies over the treatment of this stage. Traditional Chinese medicine has had unique advantages in the prevention and treatment of viral hepatitis since ancient times and plays an important role in prevention and treatment of viral hepatitis in China. Based on the pathological process of chronic HBV infection, the team of Department of Hepatology in Shenzhen Hospital of Traditional Chinese Medicine believes that the core pathogenesis of chronic HBV infection is "kidney deficiency and epidemic toxin lurking in liver blood" and established kidney-tonifying therapy for the treatment of chronic HBV infection. Under the support of the project of Prevention and Treatment of Major Infectious Diseases such as AIDS and Viral Hepatitis in The Eleventh Five Year Plan, The Twelfth Five Year Plan, and The Thirteenth Five Year Plan, the team has conducted studies on the regularity of syndromes and a series of clinical studies and investigated the clinical efficacy of kidney-tonifying therapy through multicenter, randomized, double-blind, placebo-controlled studies, thereby exploring the application and mechanism of traditional Chinese medicine treatment in patients with chronic HBV infection. However, there are still difficulties in the pathogenesis and treatment of chronic HBV infection, and with the inheritance, innovation, and modernization of traditional Chinese medicine, it is believed that traditional Chinese medicine can provide reliable regimens for the treatment of chronic HBV infection.
ABSTRACT
Objective To study the effects of tonifying kidney therapy on pathology in chronic hepatitis B virus carriers.MethodsWith the multi-center, randomized, double-blinded and placebo-controlled methods, 600 cases of chronic hepatitis B virus carriers were divided intoBushen Qingtou group,Bushen Jianpi group and control group, 200 cases in each group, and were treated withBushen Qingtou prescription,Bushen Jianpi prescription and placebo prescription respectively for 52 weeks. The pathological changes of the liver biopsy were observed by liver biopsy examination before and after treatment. Inflammatory active degree and fibrosis were scored with Knodell HAI and Ishak.Results The number of decreasing more than 2 points on Knodell HAI inBushen Qingtou group,Bushen Jianpi group and control group was 21, 18, and 6 respectively (P0.05). The number of decreasing more than 1 points on Ishak in Bushen Qingtou group,Bushen Jianpi group, and control group was 13, 12, and 9 respectively (P>0.05); the number of increasing more than 1 points on Ishak inBushen Qingtou group,Bushen Jianpi group and control group was 8, 3, and 11 respectively, with statistical significance betweenBushen Jianpi group and controlled group (P0.05), which meantBushenJianpi prescription could prevent the deterioration of liver tissue fibrosis more significantly than placebo prescription did. ConclusionTonifying kidney therapy, includingBushen Qingtou prescription andBushen Jianpi prescription, can inhibit the inflammatory activity and slow down the fibrosis progression of the chronic HBV carriers.

ABSTRACT
Objective To compare the clinical efficacy and safety of pegylated interferon α-2a (Peg IFN α-2a) or adefovir dipivoxil(ADV) monotherapy and their combination therapy in HBeAg positive chronic hepatitis B (CHB) patients. Methods An open randomized controlled multicenter clinical trial was performed. One hundred and twenty cases with CHB were divided into 3 groups: Peg IFN α-2a monotherapy (group A), ADV monotherapy (group B) and Peg IFN α-2a plus ADV combination therapy (group C). The virological response (VR), serological response (HBeAg, HBsAg clearance and seroconversion), biochemical response (BR) and sustained response (SR) were tested at week 24 and 48 of therapy and week 48 of follow-up after end of treatment (EOT) for'evaluation of therapeutic effects, safety and drug resistance. The efficacy was compared using X2 test. Results At week 48 of treatment, the VR (HBV DNA ≤500 copy/mL) rates were 36. 8%(14/38), 37. 5%(15/40) and 62. 9% (22/35), respectively in groups A, B and C; that in group C was higher than those in groups A and B (X2 = 4. 933, 4. 801, respectively; both P < 0. 05); HBeAg seroconversion rates in three groups were 44. 7% (17/38), 17. 5% (7/40) and 51. 4% (18/35), respectively. At week 48 of follow-up,SR rates in three groups were 34. 2%(13/38), 15. 0%(6/40) and 48. 6% (17/35), respectively; those in groups C and A were higher than that in group B (X2 = 9. 894,P<0. 01;X2 =3. 903, P<0. 05, respectively). Conclusions VRs at week 24 and 48 of Peg IFN α-2a plus ADV combination therapy are better than Peg IFN α-2a or ADV monotherapy. SRs at week 48 of follow-up after Peg IFN α-2a monotherapy and combination therapy are both better than ADV monotherapy.
ABSTRACT
Objective To evaluate the early diagnosis value of MRI combined with DSA in cirrhotic nodules (regenerative nodules, dysplastic nodules) becoming small hepatocellular carcinoma. Methods 40 patients diagnosed as cirrhosis and whose liver nodules detected by ultrasound were followed up as MR dynamic study. All patients were followed up by three dynamic contrast-enhanced MR scanning once every 3 months,and the changes of cirrhotic nodules were observed and analyzed in the signal. If MRI suggested cancerous nodules cirrhosis, hepatic artery DSA would be carried out. Results 40 patients were followed up for 1.5 to 3 years,all patients MR nodules were found in liver regeneration. Follow-up process, the dysplastic nodules were founded in 28 cases and the small hepatocellular carcinoma were founded in 18 patients. 16 cases of 18 patients with small hepatocellular carcinoma carried out routine DSA all had typical of hepatic arterial blood supply and angiogenesis, and were given to Integrated Traditional and Western intervention simultaneously. Conclusion Combined use of MRI-DSA in the evaluation of cirrhotic nodules had a definite value, and could find smaller hepatocellular carcinoma,provide the basis for smaller hepatocellular carcinoma therapy.
ABSTRACT
Objective To investigate the technical outline and clinical value of percutaneons transhepatic portal vein port-catheter system implantation in preventing small hepatocellular carcinoma recurrence after curative treatments. Methods Fifteen patients with small hepatocellular carcinoma after curative treatment were included in this study. Guided by ultrasound and fluoroscopy, left branch of the portal vein were punctured and port-catheter system were implanted. Then drugs infusion into portal vein system was done for preventing recurrence of hepatic carcinoma. Results Interventional operations were succeed in all 15 cases. Drugs could drop into portal vein smoothly. No operating complications occurred. Conclusion Percutaneous transhepatic portal vein port-catheter system implantation was an easy operating and micro traumatic method. This technique could play an important role in preventing recurrence.
ABSTRACT
Objective To observe the effects of serum with drug Penthorum chinense Pursh extractum on transforming growth factor (TGF)-β1 and collagen I secretions of activated hepatic stellate cells. Methods Twenty male SD rats were divided into 2 groups, and were administered with 0.9% sodium chloride solution and Penthorum chinense Pursh extraetum via gastrogavage for 3 days respectively and then sacrificed. Serum samples of these rats were collected. HSC-T6 cells were divided into the normal group and the treatment group. The cells of the normal group were incubated in Dulbecco's modified eagle medium (DMEM)with sera of normal rats, while those of the treatment group were incubated in DMEM with sera from Penthorum chinense Pursh extractum treated rats. The HSC-T6 viability was observed by AlamarBlue assay, while the toxicity of Penthorum ehinense Pursh extractum was measured by 3-(4, 5-Dimethyhhiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) assay. The expression of collagen I and TGF-β1 mRNA were determined by real timepolymerase chain reaction (real time PCR). The protein expressions of collagen I and TGF-β1 were analyzed by Western blotting. The data were analyzed by single factor analysis of variance and pairwise comparison was done by q test. Results Different concentrations of sera from Penthorum chinense Pursh extractum treated rats could all inhibit HSC-T6 proliferation, especially when the sera concentration were 10% and the HSC-T6 cells were incubated for 24 h (P＜0.01 ). MTT assay indicated that sera from Penthorum chinense Pursh extractum treated rats showed no obvious toxicity to HSC-T6 compared with those from normal rats (P ＞0.05). After 24 h incubation, 10% sera from Penthorum chinense Pursh extractum treated rats could significantly down-regulate mRNA expression of TGF-β1 and collagen I compared with normal group (TGF-β1 2.790±0.174 vs 9. 827 ± 1.429, P＜0.01 ; collagen I 1.213 ± 0.099 vs 4.053 ± 1.005, P＜0.01 ). Mcanwhile, the protein expressions of TGF-β1 and collagen I were also obviously inhibited in drug treated group compared with normal group (P＜0.01). Conclusions Serum from Penthorum chinense Pursh extractum treated rats can significantly decrease TGF-β1 and collagen I secretions of activated hepatic stellate cells, which provides the experimental evidence for liver fibrosis treatment.
ABSTRACT
Under the guidance of the Liu's theory of kidney deficiency and incubative pathogen, the authors point out that for understanding the incubative pathogen of chronic hepatitis B (CHB) you should grasp the essence of the pathogenesis, kidney deficiency. For chronic hepatitis B, it is easier to be understood and conforms to pathological characteristics of chronic hepatitis B. The property of the incubative pathogen can not be restricted to that the incubative cold changes to warm, it should be understood as epidemic heat and epidemic toxin. Therefore, the authors first put forward this hypothesis: the pathogenesis of chronic hepatitis B is kidney deficiency and damp-heat toxic pathogen incubating in liver and blood. And based on the hypothesis a comprehensive therapy including clearing away heat, expelling pathogenic factors, promoting blood circulation and tonifying the kidney is introduced.
