ABSTRACT
ObjectiveTo explore the effectiveness and safety of Yiqi Huoxue Formula (益气活血方, YHF) in the adjuvant treatment of chronic pulmonary heart disease (CPHD) and heart failure (HF)with qi deficiency and blood stasis pattern. MethodsOne hundred and twenty patients with CPHD and HF with qi deficiency and blood stasis pattern were allocated randomly into treatment group and control group, with 60 case in each group. The control group was given conventional basic western medicine, while the treatment group was given oral administration of YHF granules in addition, one dose per day. The treatment course for both groups was 8 weeks. The TCM symptom scores, Minnesota Life Quality Scale (MLHF-Q) scores, echocardiographic indicators including right ventricular end-diastolic diameter (RVEDD), left ventricular end-diastolic diameter (LVEDD), left atrial end-diastolic diameter (LAEDD) and pulmonary artery mean pressure (PAMP), six-minute walking distance (6MWD), and plasma N-terminal pro-B-type natriuretic peptide (NT-ProBNP) level were compared between the groups. The effectiveness regarding cardiac function and TCM syndromes were compared between the two groups after treatment, and the occurrence of adverse events was observed. ResultsWith two drop-outs both in the treatment group and control group, and 58 cases in each group were included in the outcome analysis. The total effective rate regarding cardiac function and TCM syndromes in the treatment group were 91.38% (53/58) and 96.55% (56/58), respectively, significantly higher than the corresponding 70.69% (41/58) and 48.27% (28/58) in the control group (P<0.05). After treatment, the TCM symptom scores and RVEDD level were significantly reduced in the treatment group, and MLHF-Q score, plasma NT-ProBNP level and PAMP level decreased significantly, while 6MWD increased in both groups (P<0.01). Compared to those in the control group, the TCM symptom scores, MLHF-Q score, plasma NT-ProBNP level and PAMP level significantly decreased, while 6MWD increased in the treatment group (P<0.01). There were no obvious abnormalities in the blood, urine, stool routine and liver and kidney function indicators in both groups. One adverse reaction each occurred in both groups, and there was no statistically significant difference in the incidence rates(P>0.05). ConclusionYHF combined with conventional western medicine can significantly improve the clinical efficacy, improve the clinical symptoms and cardiac function, increase the quality of life and exercise tolerance, and is relatively safe.
ABSTRACT
Common carp (Cyprinus carpio) is an important valuable cyprinid in China and has been a popular cultured aquaculture species around the globe. Understanding the genetic diversity of wild native common carp not only provides basic data for the protection and utilisation of common carp resources but also assesses the effect of human activities on the genetic diversity of this species. In this study, genetic diversity and population structure of the common carp from 15 sampling populations in the Pearl River and Nandujiang River were determined using a coalescent mitochondrial locus (MLS), including mitochondrial cytochrome b gene (Cytb) and a control region (D-loop) segment. The haplotype diversity and nucleotide diversity were 0.962 and 0.00628 in the Pearl River and 0.808 and 0.00376 in the Nandujiang River, respectively. Phylogenetic and haplotype network analyses indicated that three sub-species (a) C. c. rubrofuscus, (b) C. c. haematopterus and (c) C. c. carpio all occur in both rivers. AMOVA revealed that the variation within populations (86.2%) was the main source of the total variation. Statistically significant genetic differentiation among different Pearl River populations of C. c. rubrofuscus (Fst = 0.05-0.25) and relatively high genetic differentiation between the Nandujiang River population and the Pearl River populations (Fst > 0.238) are apparent. Bayesian clustering analyses detected that global populations consisted of eight genetic clusters and examined that Nandujiang River population included relatively pure genetic clusters. Neutrality tests suggested that native populations experienced recent population expansion, and Extended Bayesian Skyline Plot indicated that the common carp populations likely experienced a historical expansion during 0.125-0.250 MYA. Artificial fish propagation and release, escape from fish farms and Fang Sheng may explain the invasion of non-native sub-species in many river sections, such as Laibin, Rongjiang, Huizhou, Heyuan and Zhaoqing. To conserve the native common carp populations, release station should be established to culture native common carp fry. Overall, the findings can be contributed to complementing scientific knowledge for conservation and management of the wild native common carp.

Objective:To develop a UPLC method for determining four glycosides in microctis folium.Methods:The UPLC deter-mination was performed on an Agilent SB -C18 (3.0 mm ×50 mm, 1.8 μm) colume with 0.05% acetonitrile -phosphate solution as the mobile phase.The detection wavelength was set at 320 nm.The flow rate was 0.3 ml· min-1.The column temperature was 25℃.Results:Narcissoside, isovitexin, kaempferol-3-rutinoside and isorhamnetin-3-O-glucoside all showed good linearity with the re-covery of 98.89%,99.03%, 97.00%and 97.41%, and RSD of 0.41%, 0.84%,0.44%and 0.80%, respectively (n=9).Con-clusion:The method is convenient with good stability , repeatability and sample recovery rate , which provides basis for the quality eval-uation and control of microctis folium.
