Multi-component traditional Chinese medicines are an innovative research mode for traditional Chinese medicines. Currently, there are many design methods for developing multi-component traditional Chinese medicines, but their common feature is the lack of effective connection of the traditional Chinese medicine theory. In this paper, the authors discussed the multi-component traditional Chinese medicine design methods based on medicinal property combination modes, provided the combination methods with the characteristics of traditional Chinese medicine for the prescription combinations, and proved its feasibly with hypertension cases.

OBJECTIVETo investigate the dynamic changes that occur in T cell subsets, particularly involving the surface expression of programmed death 1 (PD-1), in response to pegylated (Peg)-interferon (IFN) a-2a therapy in patients with chronic hepatitis C virus (HCV) infection.

METHODSTwenty-five patients with HCV genotype 1b chronic infection and 10 healthy controls were enrolled in the study. All the HCV patients received combination antiviral therapy of Peg-IFNa-2a (180 mug/week) plus ribavirin. At treatment weeks 0 (baseline), 4, 12, 24 and 48, the level of PD-1 protein expression on the surface of total peripheral CD8+ and CD4+ T cells was determined by flow cytometry and the level of PD-1 mRNA expression in peripheral blood mononuclear cells (PBMCs) was determined by reverse transcription-polymerase chain reaction. Independent student's t-test were used to compare mean values between the two groups, repeat measure variance analysis was used to compare mean values among multiple groups, and Pearson's correlation coefficient was used to assess correlation significance.

RESULTSOver the course of antiviral therapy, the proportions of CD4+ T cells and CD8+ T cells, as well as the CD4+/CD8+ ratio, increased (F = 81.23, 39.28, and 7.01 respectively; all P less than 0.01). In contrast, the PD-1 protein expression frequency on CD4+ T cells and CD8+ T cells significantly declined (F = 100.11 and 158.40 respectively; all P less than 0.01). The PD-1-mRNA expression level in PBMCs was: 1.40+/-0.26 at baseline, 1.30+/-0.27 at week-4, 1.14+/-0.18 at week-12, 1.06+/-0.26 at week-24, and 0.83+/-0.25 at week-48 (F = 20.09; P less than 0.01). A positive correlation existed between the PD-1 protein expression frequencies on CD4+ T cells and CD8+ T cells and the HCV RNA load detected at baseline (r = 0.82 and 0.75 respectively; all P less than 0.01).

CONCLUSIONThe ability of Peg-IFN-a-2a-based antiviral therapy to suppress HCV replication may involve reduction of PD-1 protein expression on the surface of CD8+ T cells and CD4+ T cells.

Three representative schools of scalp acupuncture for the stroke hemiplegia such as Jiao's scalp acupuncture, Yu's scalp acupuncture and temporal three-needle are introduced and analyzed. Since the schools of scalp acupuncture are numerous and the bases of selection acupoints are complicated, it demands to determine the optimal needling acupoints by means of scientific research. Therefore, the selection acupoints would be adhering to scientific principles. The theoretical basis needs to be explored and studied further.

OBJECTIVETo review the research progress on Type IV secretion system (T4SS) in Helicobacter pylori.

DATA SOURCESThe data used in this review were identified by searching of PUBMED (1995 - 2007) online resources using the key terms 'Type IV secretion system' and 'Helicobacter pylori'.

STUDY SELECTIONMainly original articles and critical reviews written by major pioneer investigators of this field were selected.

RESULTSThe research progress on T4SS in Helicobacter pylori was summarized. The structure and function was discussed.

CONCLUSIONST4SS is not only involved in toxin secretion and injection of virulence factors into eukaryotic host target cells, but also involved in horizontal DNA transfer to other bacteria and eukaryotic cells, through DNA uptake from or release into the extracellular milieu. It provides a new insight into the pathogenicity of Helicobacter pylori and a novel target for antimicrobials development. However, many challenges remain for us in understanding the biological role of T4SS in Helicobacter pylori.

OBJECTIVETo identify the risk factors of hepatorenal syndrome in patients with hepatitis B virus (HBV)-related acute-on-chronic liver failure(ACLF).

METHODSA total of 726 hospitalized patients with HBV-ACLF were retrospectively analyzed. Data of demographic and clinical parameters (sex, age, family history, and presence of liver cirrhosis and diabetes), common complications (spontaneous bacterial peritonitis, pulmonary infection, hepatic encephalopathy, and upper gastrointestinal hemorrhage), and baseline biochemical parameters (albumin, globulin, total bilirubin, direct bilirubin, alanine aminotransferase, aspartate aminotransferase, gamma-glutamyl transferase, alkaline phosphatase, cholesterol, cholinesterase, K+, Na+, plasma thromboplastin antecedent, alpha-fetoprotein, HBV DNA, white blood cell count, hemoglobin, and platelet count) were collected from the medical records database. Univariate and multiple regression analyses were performed to determine the risk factors of hepatorenal syndrome.

RESULTSMultiple logistic regression analysis indicated that upper gastrointestinal hemorrhage [risk (R) = 1.313, relative hazard (RH) = 3.716, 95% confidence interval (CI): 2.156-6.404], hepatic encephalopathy (R = 1.120, RH = 3.065, 95% CI: 1.900-4.945), spontaneous bacterial peritonitis (R = 1.005, RH = 2.733, 95% CI: 1.379-5.417), pulmonary infection (R = 1.051, RH = 2.862, 95% CI: 1.783-4.592), and white blood cell count (R = 0.056, RH = 1.058, 95% CI: 1.010-1.107) were independent risk factors for hepatorenal syndrome development in patients with HBV-ACLF.

CONCLUSIONSeveral risk factors were significantly associated with the development of hepatorenal syndrome in HBV-ACLF, including upper gastrointestinal hemorrhage, hepatic encephalopathy, spontaneous bacterial peritonitis, pulmonary infection, and elevated white blood cell count.
