OBJECTIVETo evaluate the reliability, validity, and responsiveness of traditional Chinese medicine (TCM) clinical outcomes rating scale for heart failure (HF) based on patients' report.

METHODSTCM clinical outcomes rating scale for HF (TCM-HF-PRO) were evaluated based on 340 HF patients' report from multiple centers. The completion of the investigation was recorded. Cronbach's α coefficient and split-half reliability were used for reliability analysis, and factor analysis was used to assess the construct validity of the rating scale. Pearson correlation analysis was then used for criterion validity analysis. Discriminant analysis was used to assess the responsiveness of the scale. All 340 HF patients having complete TCM-HF-PRO data were assigned to the treatment group and the control group by central randomization. The total TCM-HF-PRO scores of the two groups were compared using paired t-test to reflect the longitude responsiveness of the scale before treatment and at week 2 after treatment.

RESULTS(1) The recycling rate of the scale was 100.0%. One of them was not filled completely, which was rejected thereby. So the completion rate was 99.7%. The completion time for TCM-HF-PRO scale ranged 15 to 25 min. (2) The Cronbach's α coefficient of rating scale was 0.903, split-half reliability was 0.844 and 0.849. (3) Confirmatory factor analysis showed that 7 factors and items formed according to maximum load factor basically coincided with the construct of the rating scale, 7 factors accumulated contribution rate was 43.8%. TCM clinical outcomes rating scale for HF based on patients' report was relatively better correlated with the Minnesota living with HF questionnaire (r = 0.726, P < 0.01). (4) Discriminant analysis showed that the rating scale correctly classified more than 78.8% of case studies having confirmed initial differential diagnosis by experts. The total scale of the rating scale decreased more in the two group after treatment, with significant difference as compared with before treatment (P < 0.01.

CONCLUSIONTCM clinical outcomes rating scale for HF based on patients' report had good reliability, validity and responsiveness, hence it could be used to assess clinical efficacy for HF patients.

OBJECTIVETo investigate the relationship between cardiac Cerebrovascular disease and serum uric acid(SUA) in the coastal inhabitant, and try to provide base for prevention of the local metabolic disease and cardiac Cerebrovascular disease.

METHODWe got 3111 local people who had participated in the annual physical examination in the perch hospital for the research on the level of SUA and the relative risk factor. According to SUA level we divided the cases into two groups. One is hyperuricemia group and the other is control group.

RESULTS(1)The average SUA level was (380.2-/+62.58) micromol/L in the males, while (290.82-/+60.32) micromlo/L in the female. The sick rate of hyperuricaemia rate, was 21.8% for male, and the 17.6% of female. This disease affected more men than women. It has significant difference (P<0.01); (2)The SUA level of the showed a positive correlation with the indexes of the total cholesterol, the triglyceride, the blood pressure and the body weight index. The SUA level in overweight/obesity people was obviously higher than that of the normal weight people.

CONCLUSIONS(1)The sick rate of hyperuricaemia is high in Zhongshan coastal area, which due to many related factors. As far as, few people know it, so we should adopt the synthesis measure to prevent and control it to reduce the sick rate; (2)the rise of The SUA level possibly becomes one of the independent dangerous and predictive factor for the heart cerebral von disease.

OBJECTIVETo carry out expert survey for traditional Chinese medicine (TCM) syndrome characteristics of different clinical types of coronary artery disease (CAD).

METHODSBy using Delphi method, we carried out two rounds of nationwide expert surveys for modern TCM characteristics of syndrome elements and syndrome types of CAD.

RESULTSBased on expert consensus, qi deficiency, blood stasis, phlegm turbidity, qi deficiency blood stasis, and intermingled phlegm and blood stasis are common TCM syndromes for different clinical types of CAD. Of them, qi stagnation, blood stasis, phlegm turbidity, heat accumulation, cold coagulation, yang deficiency, deficiency of both qi and yang were more often seen in patients with unstable angina than in those with stable angina. Qi deficiency, yin deficiency, and deficiency of both qi and yin were less seen. We could see more excess syndrome and less deficiency syndrome (such as qi deficiency, yin deficiency, etc.) in acute ST-segment elevation myocardial infarction (STEMI) than acute non-ST-segment elevation myocardial infarction (NSTEMI). Qi deficiency, blood stasis, water retention, yang deficiency, phlegm turbidity, yin deficiency, Xin-qi deficiency, and qi deficiency blood stasis induced water retention are the most common TCM syndrome types of CAD heart failure (HF). Blood deficiency, yin deficiency, heat accumulation, deficiency of both Xin and Pi, deficiency of both qi and blood, deficiency of both qi and yin, yin deficiency and fire hyperactivity were more often seen in CAD arrhythmias.

CONCLUSIONSTCM syndrome distributions of different clinical types of CAD have common laws and individual characteristics. Results based on the expert consensus supplied evidence and support for clinical diagnosis and treatment of CAD.

To study the effect of micro (mi)RNA on cellular proliferation induced by hepatitis B x protein, HBx, in human liver cells and to investigate the underlying molecular mechanism of this cancer-related effect. The human L02 hepatocyte cell line was stably transfected with HBx (L02/HBx) or an HBx mutant (L02/HBx-d382) that induces higher levels of cellular proliferation. The differential miRNA expression profiles were determined by microarray analysis and confirmed by real-time PCR. Two miRNAs, miR-338-3p and miR-551b, that were found to be significantly down-regulated in the L02/HBx-d382 cells were selected for further study and transfected individually into cells using the lipofectamine procedure. The cell survival rate was analyzed by MTT assay, and cell cycles were assessed by flow cytometry. Expressions of cyclinD1, cyclinG1, and E2F1 were assessed by real-time PCR and Western blotting. Compared with the microarray miRNA profile of L02/pcDNA3.0 cells, six miRNAs were up-regulated and five miRNAs were down-regulated in the L02/HBx-d382 cells, while four miRNAs were up-regulated and 12 were down-regulated in the L02/HBx cells. The microarray results were consistent with real-time PCR results. Transfection of miR-338-3p and miR-551b significantly inhibited the cell survival rates (P less than 0.001) and induced G0/G1 phase cycle arrest. According to MTT results: for L02/HBx-d382 cells, compared with lipofectamine or non-transfected (NC) controls, the t value of miR-338-3p was 10.402, 9.133 and the t value of miR-551b was 8.763, 7.403; for L02/HBx cells, compared with lipofectamine or NC controls, the t value of miR-338-3p was 9.105, 8.074 and the t value of miR-551b was 7.673, 7.52. According to flow cytometry results: for L02/HBx-d382 cells, compared with lipofectamine or NC controls, the t value of miR-338-3p was 12.173, 11.107 and the t value of miR-551b was 15.364, 13.377; for L02/HBx cells, compared with lipofectamine or NC controls, the t value of miR-338-3p was 15.416, 13.378, and the t value of miR-551b was 13.276, 13.109. The protein levels of cyclinD1, cyclinG1, and E2F1 were significantly reduced by both miR-338-3p and miR-551b ( P less than 0.001). For L02/HBx-d382 cells, compared with lipofectamine or NC controls: E2F1 had t = 11.132, 10.031 and 12.017, 10.973, respectively; cyclinD1 had t = 15.654, 15.013 and 15.447, 14.733, respectively; cyclinG1 had t = 8.017, 7.661 and 7.402, 7.417, respectively. For L02/HBx cells, compared with lipofectamine or NC controls: E2F1 had t = 14.244, 13.331 and 15.022, 14.468, respectively; cyclinD1 had t = 8.695, 8.137 and 7.877, 7.503, respectively; cyclinG1 had t = 7.73, 7.471 and 7.596, 7.41, respectively. In contrast, the mRNA levels for E2F1, cyclinD1, and cylcinG1 showed no significant differences between the miRNA transfected cells and controls. Wild-type HBx and the high proliferation-inducing mutant HBx can influence the miRNA expression profile of L02 cells. HBx down-regulates miR-338-3p and miR-551b in L02 cells, and the high proliferation-inducing mutant has a more robust effect. The mechanism of miR-338-3p- or miR-551b-mediated cell growth inhibition appears to be related to the direct modulation of cyclinD1, cyclinG1, and E2F1.

OBJECTIVESTo compare the outcomes after liver resection for a single small hepatocellular carcinoma (HCC) (≤ 5 cm) between non-cirrhotic patients and cirrhotic patients, and to explore the influence of liver cirrhosis on recurrence and overall survival after liver resection in patients with a single small HCC.

METHODSA consecutive series of 256 patients with a single small HCC undergoing liver resection from April 2001 to October 2009 was retrospectively reviewed. Among the 256 patients, 227 patients were male, and 29 were female. The medium age was 49 years (ranged, 14 - 79 years); 224 (87.5%) patients were positive for hepatitis B surface antigen, 241 (94.1%) patients were with preoperative liver function of Child-Pugh grade A. The entire cohort were divided into non-cirrhosis group (n = 44) and cirrhosis group (n = 212). Univariate analysis and then multivariate analysis were performed to determine the prognostic factors of recurrence and overall survival after liver resection for all patients.

RESULTSThe 1-, 3-, 5-year recurrence-free survival rates after liver resection were 93.0%, 85.3%, and 68.5%, respectively, in non-cirrhosis group, while 81.1%, 58.6%, and 45.0%, respectively, in cirrhosis group. The 1-, 3-, 5-year overall survival rates after liver resection were 100%, 92.5%, and 92.5%, respectively, in non-cirrhosis group, while 93.8%, 78.7%, and 67.8%, respectively, in cirrhosis group. Both the recurrence-free survival and overall survival of non-cirrhosis group were significantly better than those of cirrhosis group (χ(2) = 8.756, P = 0.003; χ(2) = 8.603, P = 0.003). Cirrhosis, absence of tumor capsule, presence of microvascular invasion and moderate/poor tumor differentiation were the independent adverse prognostic factors for recurrence-free survival and overall survival in patients with a single small HCC after liver resection.

CONCLUSIONSCirrhosis is an important adverse prognostic factor for long-term survival in patients with a single small HCC after liver resection. Liver resection resulted in much worse survival for cirrhotic patients compared to non-cirrhotic patients.

AX15 is a mutein of naturally occurring human ciliary neurophic factor (hCNTF), with improved biological activity, stability and solubility. AX15 is susceptible to protease degradation when expressed in Pichia pastoris. Amino acid sequencing revealed the degradation was occurred behind position 12 and 13 amino acid residues, which constitute a dibasic site, RR. Based on the substrate specificity of KEX2, a KEX2 resistant mutein of AX15-AX15 (R13K) was constructed, in which RR was replaced by RK. It was demonstrated that the stability of AX15 (R13K) improved significantly, as no degradation was detected even after 120 hours of induction. AX15 (R13K) was purified to homogeneity by ultrafiltration and gel filtration. TF-1 cell survival bioassay showed AX15 (R13K) had equivalent specific activity to AX15. The protease resistant mutein of AX15 may have greater in vivo stability and thus have superior therapeutic potential.

OBJECTIVETo evaluate the clinical value of perioperative adjuvant chemotherapy in prevention of tumor recurrence and improvement of patient survival after liver transplantation for advanced hepatocellular carcinoma (HCC).

METHODSTwenty patients with advanced HCC (pTNM stages III and IV a) receiving liver transplantation with preoperative transcatheter arterial chemoembolization (TACE) and postoperative adjuvant chemotherapy (ADM+5-Fu+CDDP) were retrospectively reviewed in comparison with 16 patients receiving liver transplantation only for tumor recurrence, cumulative and tumor-free survivals. The feasibility and side-effects of the treatments were also studied.

RESULTSThe recurrence rate was lower in the perioperative treatment group than in non-treatment group (12/20, 60.0% vs 11/16, 87.5%, P<0.05). The 1- and 2-year overall survival rates were 70.8% and 47.1% for the chemotherapy group and 43.8% and 20.5% for the non-chemotherapy group respectively, showing significant differences between them (P<0.05). The 1- and 2-year tumor-free survival rates were 60.6%, 40.5% and 33.6%, 15.6% in the two groups, respectively, with also significant differences (P<0.05).

CONCLUSIONSPerioperative adjuvant treatment may significantly decrease the likeliness of tumor recurrence and prolong the survival of patients with advanced HCC after liver transplantation. Chemotherapy with ADM+5-Fu+CDDP can be effective and safe with only mild side-effects.
