Remaining organic and functional damage of ischemia cardio-cerebrovascular disease is always a main trouble puzzling the clinicians. After the discovery of endothelial progenitor cells (EPCs), researchers realize that postnatal angiogenesis is an important biological process, which play a key role to repair the ischemia tissue and improve the function. So a new concept which names therapeutic angiogenesis supply a new treament way for the ischemia cardio-cerebrovascular disease. Traditional Chinese medicine (TCM) has accumulated rich experience on treating the ischemia disease, studies found that many Chinese medicine prescriptions and effective ingredients can increase the therapeutic angiogenesis, howerer the mechanisms were not the same, they mainly manifest in regular the secretion of angiogenic factors, increase the proliferation and differentiation etc. In this paper, we review recent studies, summary the Chinese medicine prescriptions and effective ingredients which can increase the therapeutic angiogenesis, and analyze the differernt pathway. We view to provide reference for the later researchers.

OBJECTIVETo observe the Chinese medicine constitution types and human leukocyte antigen (HLA)-DQA1 gene polymorphism in patients with hepatitis B (HB) virus infection in Chinese Han population of Zhejiang Province, for exploring the roles of constitution factor in pathogenesis of HB.

METHODSA total of 240 subjects, including 120 biopsy-proven chronic HB (CHB), 60 HB asymptomatic carrier (ASC) and 60 resolved from HBV infection spontaneously (RHBS) were studied. Their Chinese medicine constitution type was judged by Wangqi's classification, and their genotype of HLA-DQA1 was detected by polymerase chain reaction sequence specific primer for comparing the difference between groups in distribution frequency (DF) of constitution types and genes.

RESULTS(1) As compared with the RHBS group, DF of yin-deficiency constitution and phlegm-dampness constitution in the CHB group was significant higher (20.0% vs. 6.7% and 12.5% vs. 1.7%), and that of placid constitution was significant lower (11.7% vs. 31.7%), showing statistical significance between groups (OR = 3.5, 95% CI: 1.16-10.60; OR = 8.4, 95% CI: 1.09-65.42; OR = 0.161, 95% CI: 0.076-0.34; all P < 0.05). (2) As compared with the ASC group, DF of damp-heat constitution was significant higher (24.2% vs. 6.7%, P < 0.05, OR = 4.462, 95% CI: 1.49-13.36), and that of placid constitution was significant lower (11.7% vs. 45.0%, P < 0.01, OR = 0.285, 95% CI: 0.13-0.62) in the CHB group. (3) As compared with RHBS group, DF of HLA-DQA1 * 0201 allele in CHB group was significant higher (38.3% vs. 5.8%, P < 0.01, OR = 10.04, 95% CI: 4.48-22.48); and that of HLA-DQA1 * 0102 allele was significant lower (9.6% vs. 36.7%, P < 0.01, OR = 0.183, 95% CI: 0.10-0.32). (4) As compared with ASC group, DF of HLA-DQA1 * 0201 allele in CHB group was significant higher (38.3% vs. 7.5%, P < 0.01, OR = 7.667, 95% CI: 3.7-15.87), and that of HLA-DQA1 * 0102 allele was significant lower (20.0% vs. 9.6%, P < 0.01, OR = 0.424, 95% CI: 0.23-0.79).

CONCLUSIONBoth Chinese medicine constitution and HLA-DQA1 gene polymorphism show connection with the outcomes of HB virus infection in Chinese Han population, but the real association between them is required for further study.

OBJECTIVETo observe the correlation between constitution of yin deficiency syndrome (YDS) and polymorphism of HLA-DQA1/treatment response of Peg-lFNalpha therapy in HBeAg positive chronic hepatitis B (CHB) patients, and to explore constitution of Chinese medicine (CM) in response of interferon therapy.

METHODSTotally 120 HBeAg positive CHB patients who were treated with Peg-IFNalpha were enrolled, and assigned to YDS group (59 cases) and non-YDS group (61 cases) according to classification of CM constitutions. All patients were subcutaneously injected with Peg-IFNalpha-2b (1.0 microg/kg body weight) or Peg-IFNalpha-2a (180 microg), once per week. Effective efficacy was primarily judged when complete response (CR) or partial response (PR) was obtained at month 6. Those with CR or PR completed 1 year therapeutic course. HLA-DQA1 gene types were detected by polymerase chain reaction sequence specific primers (PCR-SSP). The distribution difference of CM constitutions in patients with CR or PR and their inter-group HLA-DQA1 allele frequency were compared.

RESULTSDifferent treatment responses of Peg-IFNalpha were observed in CHB patients of two different CM constitutions. The ratio of CR + PR was 61.0% (36/59) in YDS group, obviously lower than that in NYDS group [78.7% (48/61), P < 0. 05]. Patients with CR had a lower allele frequency of HLA-DQA1 * 0501 than those with no-response [14.8% (8/54) vs. 30.6% (22/72)] with statistical difference (P < 0.05). Patients with CR had a higher allele frequency of HLA-DQA1 * 0601 than those with no-response [18.5% (10/54) vs. 5.6% (4/72)] with statistical difference (P < 0.05). The allele frequency of HLA-DQA1 * 0301 was lower in YDS group than in non-YDS group [2. 5% (3/118) vs. 9.8% (12/122)] with statistical difference (P < 0.05). The allele frequency of HLA-DQA1 * 0501 was higher in YDS group than in non-YDS group [33.9% (40/118) vs. 18.9% (23/122)] with statistical difference (P < 0.05). Yet statistical significance was lost after adjustment (Pc > 0.05 for both).

CONCLUSIONSBoth constitutions of CM and HLA-DQA1 gene polymorphism af- fect HBeAg positive CHB patients' response to Peg-INFalpha. Constitutions of YDS and HLA-DQA1 * 0501 was not favorable to response, their association needed to be further studied.

OBJECTIVETo study on the correlation between chronic asymptomatic HBV carriers (ASC) of yin asthenia constitution and genotypes of HLA-DRB1 and HLA DQA1 alleles.

METHODSTotally 105 ASC were assigned to two groups according to their constitutions, i.e., the yin asthenia group (47 cases) and the non-yin asthenia group (58 cases). The genotypes of HLA-DRB1 and HLA DQA1 alleles were determined using PCR-SSP.

RESULTSThe gene frequency of HLA-DRB1 * 09 allele and HLA-DQA1 * 0301 allele (being 12.1% and 19.1%) were obviously lower in the yin asthenia group than in the non-yin asthenia group (being 27.8% and 39.7%, P < 0.05). The gene frequency of HLA-DRB1 * 11 allele and HLA-DQA1 * 0501 allele were obviously higher in the yin asthenia group (being 12.1% and 28.7%) than in the non-yin asthenia group (4.3% and 9.5%), showing statistical difference (P < 0.05, P < 0.01).

CONCLUSIONSHLA-DRB1 * 09 allele and HLA-DQA1 * 0301 allele might be the molecular bases for non-yin asthenia patients with ASC. HLA-DRB1 * 11 allele and HLA-DQA1 * 0501 allele might be the molecular bases for yin asthenia patients with ASC.

To compare the efficacy and safety of Lamivudine (LAM) plus Adefovir dipivoxil (ADV) combination therapy and Entecavir (ETV) monotherapy for chronic hepatitis B patients. 120 patients with chronic hepatitis B managed in a single-centre clinical practice (median 96 weeks) were split into 2 cohorts, one was treated with de-novo combination Lamivudine (100 mg/day) plus Adefovir (10 mg/day) (LAM+ADV), the other with Entecavir (0.5 mg/day) monotherapy. Serum levels of ALT, creatinine, HBsAg, HBeAg and HBV viral load, together with genotypic resistence were analyzed at 0, 12, 24, 48, 96 weeks, respectively. HBV DNA was determined by real-time PCR. HBsAg and HBeAg were assessed by chemiluminescence. Serum levels of ALT and creatinine were detected by automatic biochemical analyzer. HBV genotypic resistence was tested by direct sequencing. (1) At the time point of 96 weeks, a total of 99 patients (51 cases in combination therapy cohort and 48 case in monotherapy cohort) were compared. The baseline characteristics as for HBV viral load, median age, serum levels of ALT and creatinine were compatible between combination therapy cohort and monotherapy cohort. (2) The rates of HBV DNA values is less than 300 copies/ml and HBV DNA values is less than 1000 copies/ml had no significant difference between LAM + ADV and ETV cohorts by the 12 and 24 weeks (P more than 0.05). (3) At the time point of 48 weeks, the rates of HBV DNA is less than 1000 copies/ml, HBeAg seroconversion, and ALT normalization were similar in both cohorts, though the rate of HBV DNA values is less than 300 copies/ml was obviously higher in combination therapy cohort than that of monotherapy cohort (90.7% vs 76%, P values is less than 0.05). (4) At the time point of 96 weeks, the rates of HBV DNA values is less than 300 copies/ml (96.1% vs 79.2%), HBV DNA values is less than 1000 copies/ml (98% vs 87.5%) and the HBeAg seroconversion (41.7% vs 16.7%) were markedly higher in combination therapy cohort than those of monotherapy cohort statistically (P values is less than 0.05 for all). The mean values of decreases for HBV viral loads and HBsAg levels were smilar in both cohorts at 48 and 96 weeks. (5) Elevated serum creatinine not be found in both cohorts at the end of treatment. (6) No virological breakthrough occurred in combination therapy cohort at the end of treatment. Four patients in monotherapy cohort were found with virological breakthrough at 96 weeks and three cases among were confirmed to be of variants associated with ETV resistance (rtL180M + T184L + M204V). Present study suggests that Lamivudine plus Adefovir dipivoxil de-novo combination therapy was more efficacious than Entecavir monotherapy for CHB patients and the tolerance is compatible.

Objective To detect the level of Serum and liver tissue TGF-β1 in patients with chronic hepatitis B, to study their relation to liver fibrosis and gain the evidence for diagnosis of liver fibrosis. Methods The liver fibrosis grades(S0-S4) of 131 cases with chronic HBV infection were diagnosed after liver biopsy. Serum TGF-β1 was detected by enzyme-linked immunosorbent assay, and the semiquantitative analysis was applied after detecting the expression of TGF-β1 in liver tissue with immunohistochemistry. Their relations to liver fibrosis were analyzed. Results Serum and tissue level of TGF-β1 increased significantly with the development of fibrosis, and the same result was obtained between themselves(P＜0.01). There was very significant difference for Serum level of TGF-β1 among the groups with different fibrosis grades (P＜0.01). Serum levels of TGF-β1 were decreased significantly comparing the Group S0 or S1 to S4(P＜0.005). There were significant difference for Serum level of TGF-β1 among S0 and the others(P＜0.005). And there was significant difference between S1 and S3(P＜0.005) .The expression level of TGF-β1 in liver tissue has no significant difference between group S3 and S4 (P＞0.05). However, the differences were significantly among the others comparisons(P＜0.01). Conclusion There is close relation between the level of TGF-β1 and the different liver fibrosis grades due to chronic hepatitis B. The serum level of TGF-β1 is a potential noninvasive maker for diagnosis of liver fibrosis.
