OBJECTIVETo observe interventional effects of anti-viral therapy and Compound Qin-gre Granule (CQG) on host cellular immune functions of acute virus infection patients.

METHODSThirty acute virus infection patients were recruited to detect peripheral lymphocyte subsets. They were randomly assigned to two groups, the Western medicine treatment group (treated with anti-virus Western medicine) and the integrative medicine treatment group (treated with anti-virus Western medicine plus CQG). T-cell subsets were re-examined 7 days later. Changes between before and after treatment were observed. Effect on host cellular immune functions and efficacy were compared between the Western medicine treatment and the integrative medicine treatment.

RESULTSCompared with the normal control group, the percentage of peripheral T cells increased, and the percentage of B/NK cells decreased in acute virus infection patients (P < 0.01). Meanwhile, in T cell subsets, the percentage of CD8+ T cells and CD8+ CD38+ T cells increased (P < 0.05, P < 0.01); and percentages of CD4+ T cells, CD4+ CD28 + T cells, and CD8+ CD28+ T cells decreased (P < 0.05, P < 0.01). After one-week treatment, percentages of CD4+ T cells, CD4+ CD28+ T cells, and CD8+ CD28+ T cells increased (P < 0.05, P < 0.01), while the percentage of CD8+ CD38+ T cells decreased (P < 0.01). More significantly, these changes were greater in the integrative medicine treatment group than in the Western medicine treatment group (P < 0.05).

CONCLUSIONSDisarranged cellular immune functions existed in acute virus infection patients. CQG could significantly improve viral infection induced immunologic derangement and immunologic injury.

OBJECTIVETo observe preventive and therapeutic effect of Yifei Jianpi Recipe (YJR) on chronic obstructive pulmonary disease (COPD) model rats and to explore its mechanism from the way of airway inflammation and airway mucus hypersecretion.

METHODSThe COPD rat model was established by using cigarette smoking combined with intratracheal injection of lipopolysaccharide (LPS). Male SD rats were randomly divided into the blank control group (control group), the model group, the YJR group, 6 in each group. Forced vital capacity (FVC), forced expiratory volume in 0. 1 second (FEV0. 1), FEVO. 1/FVC, peak expiratory flow (PEF) was tested by lung function device. Pathological changes of bronchi and lung tissues were observed by HE staining. Airway Goblet cells were observed using AB-PAS staining. Contents of IL-8, IL-17, and TNF-α in bronchoalveolar lavage fluid (BALF) were measured by enzyme-linked immunosorbent assay (ELISA). Protein expressions of intercellular cell adhesion molecule-1 (ICAM-1), nuclear factor KB (NF-KB), mucin 5AC (Muc5AC), and Toll-like receptor 4 (TLR4) in rat airway were detected by immunohistochemical assay. mRNA expressions of TLR4 and Muc5AC in bronchi and lung tissues were detected by real-time quantitative PCR (RT qPCR).

RESULTSChanges of bronchi and lung tissues in the model group rats were consistent with typical pathological manifestations of COPD. Compared with the model group, the degree of lung injury was significantly alleviated in the YJR group. Compared with the control group, FVC, FEV0. 1, FEVO. I/FVC, and PEF were decreased (P <0. 01), contents of IL-8, IL-17, and TNF-α in BALF were significantly increased (P <0. 01), protein expressions of ICAM-1, NF-KB, Muc5AC, and TLR4, mRNA expression levels of Muc5AC and TLR4 in bronchi and lung tissues were also significantly increased in the model group (P <0. 01). Compared with the model group, FVC, FEV0. 1, FEV0. 1/FVC, and PEF were significantly increased in the YJR group (P <0. 01, P <0. 05), but the rest indices were significantly lowered (P <0. 01, P <0. 05).

CONCLUSIONYJR could decrease contents of IL-8, IL-17, and TNF-α in BALF of COPD model rats, inhibit protein expression levels of ICAM-1, NF-κB, Muc5AC, and TLR4.in airway and lung tissues, thus playing preventive and therapeutic roles by reducing airway inflammation and airway mucus hypersecretion.

A study was made on the pharmacokinetic regularity of effective components salvianolic acid B and ferulic acid in Salviae Miltiorrhizae Radix et Rhizoma (SMRR) and Chuanxiong Rhizoma(CR) in rats, so as to discuss the compatibility mechanism of Salviae Miltiorrhizae Radix et Rhizoma and Chuanxiong Rhizoma. Rats were randomly divided into three groups and intravenously injected with 50 mg x kg(-1) salvianolic acid B for the single SMRR extracts group, 0.5 mg x kg(-1) ferulic acid for the single CR extracts group and 50 mg x kg(-1) salvianolic acid B + 0.5 mg x kg(-1) ferulic acid for the SMRR and CR combination group. The blood samples were collected at different time points and purified by liquid-liquid extraction with ethyl acetate. With chloramphenicol as internal standard (IS), UPLC was adopted to determine concentrations of salvianolic acid B and ferulic acid. The pharmacokinetic parameters of salvianolic acid B and ferulic acid were calculated with WinNonlin 6.2 software and analyzed by SPSS 19.0 statistical software. The UPLC analysis method was adopted to determine salvianolic acid B and ferulic acid in rat plasma, including linear equation, stability, repeatability, precision and recovery. The established sample processing and analysis methods were stable and reliable, with significant differences in major pharmacokinetic parameters, e.g., area under the curve (AUC), mean residence time (MRT) and terminal half-life (t(1/2)). According to the experimental results, the combined application of SMRR and CR can significantly impact the pharmacokinetic process of their effective components in rats and promote the wide distribution, shorten the action time and prolong the in vivo action time of salvianolic acid B and increase the blood drug concentration and accelerate the clearance of ferulic acid in vivo.
