[Effect of yifei jianpi recipe on inflammatory cells, levels of interleukin-8 and tumor necrosis factor-alpha in sputum from patients with chronic obstructive pulmonary disease].

OBJECTIVE: To explore the effect and the mechanism of yifei jianpi recipe (YFJPR) on patients with chronic obstructive pulmonary disease (COPD). METHODS: Forty patients with COPD in stable phase were randomly divided into two groups, the treated group and the control group. Indexes including the total and differential count of inflammatory cell in sputum, levels of interleukin-8 (IL-8) and tumor necrosis factor-alpha (TNF-alpha), as well as the percentage of forced expiratory volume in one second in its predicted value (FEV1%) and ratio of FEV1/forced vital capacity (FVC) in patients were measured before and after treatment, and compared with those in 20 healthy subjects. RESULTS: All the indexes measured in patients before and after treatment were significantly different from those in healthy subjects (P < 0.01). Differential count of polymorphonuclear neutrophil (PMN) and levels of IL-8 and TNF-alpha in sputum in the treated group significantly decreased after treatment (P < 0.01), while the non-PMN differential count and levels of FEV1% and FEV1/FVC significantly increased (P < 0.01). But in the control group, changes only showed in increasing of FEV1% and FEV1/FVC (P < 0.05 or P < 0.01). And the effects in the treated group were better than those in the control group (P < 0.01). CONCLUSION: YFJPR can play a therapeutic role on patients with COPD by way of reducing the airway inflammatory reaction.

Effectiveness of Bufei Yishen Granule combined with acupoint sticking therapy on quality of life in patients with stable chronic obstructive pulmonary disease.

OBJECTIVE: To evaluate the efficacy of Bufei Yishen Granule BFYSG) combined with Shufei Tie acupoint sticking therapy on quality of life of patients with stable chronic obstructive pulmonary disease (COPD). METHODS: A multi-center, double-blinded, double-dummy and randomized controlled method was adopted in this trial. A total of 244 patients were randomly assigned to a trial group and a control group according to the random number, each with 122 patients; treatment allocation occurred when the participants met the inclusion criteria and signed the informed consent form. In the trial group, patients were treated with BFYSG combined with "Shufei Tie" acupoint sticking therapy and sustained-release theophylline dummy, and in the control group patients were treated with oral sustained-release theophylline and BFYSG dummy combined with "Shufei Tie" acupoint sticking therapy dummy. The therapeutic course for two groups was 4 months and the follow-up was 6 months. The frequency and duration of acute exacerbation calculated by adding up each frequency and duration of acute exacerbation in treatment and follow-up time respectively, the quality of life measured by the World Health Organization Quality of Life (WHOQOL)-BREF scale and adult COPD quality of life (COPD-QOL) scale were observed. RESULTS: Among the 244 enrolled patients, 234 were screened for full analysis set (FAS); 221 were screened for per-protocol analysis set (PPS). After 4-month treatment and 6-month follow-up there were differences between the trial group and the control group in frequency of acute exacerbation (FAS: P=0.013; PPS: P=0.046); duration of acute exacerbation (FAS: P=0.005; PPS: P=0.006); scores of physiological, psychological and environment aspects of the WHOQOL-BREF questionnaire (FAS: P=0.002, P=0.006, P=0.000; PPS: P=0.00, P=0.001, P=0.000); scores of daily living ability, social activity, depression symptoms aspects of the COPD-QOL questionnaire (FAS: P=0.000, P=0.000, P=0.006; PPS: P=0.002, P=0.001, P=0.001). CONCLUSION: BFYSG combined with acupoint sticking therapy could improve the quality of life of patients with stable COPD.

Molecular analysis of spring viraemia of carp virus in China: a fatal aquatic viral disease that might spread in East Asian.

Spring viraemia of carp (SVC) is a fatal viral disease for cyprinid fish, which is caused by spring viraemia of carp virus (SVCV). To date, no SVC outbreak has been reported in China. Between 1998 and 2002, outbreaks of SVC were reported in ornamental and wild fish in Europe and America, imported from multiple sources including China. Based on phylogenetic analysis, the viral strain isolated from America was shown to be originated from Asia. These outbreaks not only resulted in huge economic losses, but also raise an interesting question as to whether SVCV really exists in China and if so, is it responsible for SVC outbreaks? From 2002 to 2006, we screened 6700 samples from ornamental fish farms using the cell culture method of the Office International des Epizooties (OIE), and further verified the presence of SVCV by ELISA and real-time quantitative RT-PCR. Two infected samples were found and the complete genome of SVCV was sequenced from one of the isolates, termed SVCV-C1. Several unique hallmarks of SVCV-C1 were identified, including six amino acid (KSLANA) insertion in the viral RNA-dependent RNA polymerase (L) protein and ten nucleotide insertion in the region between glycoprotein (G) and L genes in European SVCV strains. Phylogenetic tree analysis of the full-length G protein of selected SVCV isolates from the United Kingdom and United States revealed that G proteins could be classified into Ia and Id sub genogroups. The Ia sub genogroup can be further divided into newly defined sub genogroups Ia-A and Ia-B. The isolates derived from the United States and China including the SVCV-C1 belongs to in the Ia-A sub genogroup. The SVCV-C1 G protein shares more than 99% homology with the G proteins of the SVCV strains from England and the United States, making it difficult to compare their pathogenicity. Comparison of the predicted three-dimensional structure based on the published G protein sequences from five SVCV strains revealed that the main differences were in the loops of the pleckstrin homology domains. Since SVCV is highly pathogenic, we speculate that SVC may therefore pose a serious threat to farmed cyprinid fish in China.
