S801 leukemic cell line established by our department was used as cells for interferon (IFN) induction and stimulating induction. S801 cell culture of concentration of 5-8x10~6 cells/ml was used for IFN induction and IFN titer of 3.55 Lg IU/ml was obtained by classical procedure. The IFN titer obtained S801 cell cultures after pretreatment with Ciwujia eleutherosides B. D and E or polysaccharide (PES) combined with priming procedure,then using Sendai Virus as an inducer was 10-20 times higher than that in cultures without any pretreatment. These Chinese medical herbs may be the ideal IFN helpinducers. This cell line may be applied for IFN production.

OBJECTIVETo explore the effect of Xinfeng Capsule (XC) on lipoprotein metabolism of rheumatoid arthritis (RA) patients.

METHODSTotally 180 RA patients were assigned to the experimental group and the control group by random digit table, 90 in each group. Patients in the experimental group took XC (three pills each time, three times daily), while those in the control group took Methotrexate Tablet (four tablets each time, once per week). One month consisted of one therapeutic course and all patients were treated for two therapeutic courses. A healthy control group consisting of 60 patients was also set up. Changes of lipoprotein indices, clinical efficacy, lipid metabolism, joint symptoms and signs, activity indicators were observed, and correlation analyses were performed.

RESULTSCompared with the healthy control group, expression levels of prealbumin (PA), globulin (GLO), high-density lipoprotein (HDL), apolipoprotein Al (Apo-A1) were lowered in RA patients (P <0. 05, P <0. 01). Correlation analyses showed that PA was negatively correlated with joint tenderness, morning stiffness time, disease activity score (DAS-28), C-reactive protein (CRP), interleukin (IL)-6, respectively. Total protein (TP) was negatively correlated with joint tenderness. GLO was negatively correlated with joint tenderness and DAS-28. HDL was negatively correlated with erythrocyte sedimentation rate (ESR) and endothelin (ET)-1. Apo-Al was negatively correlated with joint pain; Apo-B was negatively correlated with CRP; LDL was negatively correlated with morning stiffness time (P <0. 05, P <0. 01). Compared with before treatment, expression levels of PA, HDL, Apo-A1 , Apo-B, and serum IL-10 contents increased, and expression levels of ESR, CRP, IL-6, ET-1 , joint pain, joint swelling, morning stiffness time, and DAS-28 decreased in the experimental group (P <0. 05, P <0. 01). PA increased more after treatment than before treatment in the control group (P <0. 01). There was statistical difference in joint symptoms (except joint tenderness) and activity indices (except ET-1) in the control group (P <0. 05, P <0. 01). Compared with the control group after treatment, PA and HDL increased, ET-1 and duration of morning stiffness decreased in the experimental group (all P <0. 05).

CONCLUSIONSLipoprotein metabolic disorder exists in RA patients, and it is associated with disease activity. XC could obviously improve lipoprotein metabolism and joint symptoms.

To evaluate the efficacy and safety of acupuncture combined with traction therapy for lumbar disc herniation, providing the basis for future research strategies. Randomized control trials. (RCT) of acupuncture combined with traction therapy for lumber disc herniation at home and abroad from 2000 to 2013 were searched, analysis and evaluation of literature and strength of evidence were based on the principles and methods of Evidence-based Medicine. The total effective rate and curative rate were considered as primary outcome measures; pain improvement, quality of life, relapse rate and adverse effects were considered as secondary outcome measures. Seventeen RCTs were identified, Meta-analysis showed that (1) total effective rate and curative rate: acupuncture combined with traction therapy was better than single therapy (acupuncture or traction); (2) pain improvement: acupuncture combined with traction therapy was better than traction therapy; (3) relapse rate: current evidence could not support the conclusion that acupuncture combined with traction therapy was better than traction therapy. Acupuncture combined with traction therapy for lumbar disc herniation was effective. However, the included studies were with high risk of bias, important outcome measures such as quality of life, relapse rate and adverse effects were not found in most of the studies. Current evidence has not yet been able to fully reflect acupuncture combined with traction therapy for lumbar disc herniation is better than single therapy, so more RCTs of higher quality are needed to further confirm its efficacy and safety.

The purpose of this study was to evaluate the impact of callus induction and culture conditions on secondary metabolic diversity of the callus cell lines of traditional Chinese medicinal plant Glycyrrhiza sp. (Glycyrrhiza) by combined chemical analysis and HPLC fingerprint. These callus induction conditions included two Glycyrrhiza species, two types of explants, light and dark conditions, and two combinations of hormones. The evaluation was firstly based on the contents of total flavonoids in the callus by chemical analysis and one way ANOVA. The content of total flavonoids in callus was significantly (P < 0.05) influenced by Glycyrrhiza species, light condition, and the combination of hormones. The callus was further evaluated using diversity factor based on the comparison of HPLC fingerprints of these callus cell lines. Diversity factor varies significantly for calli induced under different conditions, with the highest being at 0.45 under light condition and combination of hormones. These results provide important knowledge for the selection of suitable callus cell lines for the production of pharmacologically important secondary metabolites or bioactive fractions by in vitro culture of Glycyrrhiza sp.
