Chinese materia medica resource (CMM resource) is the foundation of the development of traditional Chinese medicine. In the study of sustainable utilization of CMM resource, adopting innovative theory and method to find new CMM resource is one of hotspots and always highlighted. Pharmacophylogeny interrogates the phylogenetic relationship of medicinal organisms (especially medicinal plants), as well as the intrinsic correlation of morphological taxonomy, molecular phylogeny, chemical constituents, and therapeutic efficacy (ethnopharmacology and pharmacological activity). This new discipline may have the power to change the way we utilize medicinal plant resources and develop plant-based drugs. Phylogenomics is the crossing of evolutionary biology and genomics, in which genome data are utilized for evolutionary reconstructions. Phylogenomics can be integrated into the flow chart of drug discovery and development, and extends the field of pharmacophylogeny at the omic level, thus the concept of pharmacophylogenomics could be redefined in the context of plant pharmaceutical resources. This contribution gives a brief discourse of knowledge pedigree of pharmacophylogeny, epistemology and paradigm shift, highlighting the theoretical and practical values of pharmacophylogenomics. Many medicinally important tribes and genera, such as Clematis, Pulsatilla, Anemone, Cimicifugeae, Nigella, Delphinieae, Adonideae, Aquilegia, Thalictrum, and Coptis, belong to Ranunculaceae family. Compared to other plant families, Ranunculaceae has the most species that are recorded in China Pharmacopoeia (CP) 2010. However, many Ranunculaceae species, e. g., those that are closely related to CP species, as well as those endemic to China, have not been investigated in depth, and their phylogenetic relationship and potential in medicinal use remain elusive. As such, it is proposed to select Ranunculaceae to exemplify the utility of pharmacophylogenomics and to elaborate the new concept empirically. It is argued that phylogenetic and evolutionary relationship of medicinally important tribes and genera within Ranunculaceae could be elucidated at the genomic, transcriptomic, and metabolomic levels, from which the intrinsic correlation between medicinal plant genotype and metabolic phenotype, and between genetic diversity and chemodivesity of closely related taxa, could be revealed. This proof-of-concept study regards pharmacophylogenomics as the updated version of pharmacophylogeny and would enrich the intension and spread the extension of pharmacophylogeny. The interdisciplinary knowledge and techniques will be integrated in the proposed study to promote development of CMM resource discipline and to boost sustainable development of Chinese medicinal plant resources.

This study was aimed to diffuse the lung and promote urination for the observation of cardiopulmonary re-lated index change of cor pulmonale rats to further explore the treatment effect on the pulmonary function, pulmonary arterial hypertension (PAH) and the influence of right heart hypertrophy of rats, in order to further illustrate the ef-fect of diffusing the lung and promoting urination for cor pulmonale. Sixty Wistar rats were randomly divided into the control group, model group and Xiao-Qing-Long decoction (XQLD) group with 20 rats in each group. The AniRes2003 animal lung function analysis system was applied to measure the pulmonary function of rats. And the multi-guide physiological recorder was used in the recording of the pulmonary artery pressure of rats. The conven-tional weighing method was applied to calculate and obtain the change of right heart hypertrophy. The results showed that compared to the control group, symptoms in the model group became severe obviously, which include reduced activity, slow movement and occasional airway sputum sound, and the right heart hypertrophy index of the model group increased obviously (P < 0.01). Compared to the model group, the pulmonary function and pulmonary artery pressure of the XQLD group have obvious difference (P< 0.05). It was concluded that to diffuse the lung and pro-mote urination can effectively improve the pulmonary function, PAH and the right heart hypertrophy index of rats with cor pulmonale (fluid retention). The effect of this method is definite in the treatment of cor pulmonale.

Objective To detect the epidemiologic features of pediatric patients with fall from height injury in an effort to provide a reference for prevention and scientific treatment.Methods Data of pediatric patients with fall from height injury treated from January 2011 to December 2012 were collected in the form of questionnaires.Epidemiologic features and relationship of associated factors were measured.Results Pediatric fall injury occurred very often in warmer season,namely on April and May,and in a day,it was more likely to happen when parents slacked at noon and night.Stairs and balconies were the most common sites of falls and head was most vulnerable to the injury.Falling height was the primary factor to the severity of injury.Conclusion To strengthen the protection reform in key areas,the supervision in peak time for falls and the care to children of the migrant workers can reduce fall injury in a certain extent.

With the surge of high-throughput sequencing technology, it is becoming popular to perform the phylogenetic study based on genomic data. A bundle of new terms is emerging, such as phylogenomics, pharmacophylogenomics and phylotranscriptomics, which are somewhat overlapping with pharmaphylogeny. Phylogenomics is the crossing of evolutionary biology and genomics, in which genome data are utilized for evolutionary reconstructions. Pharmaphylogeny, advocated by Prof. Pei-gen Xiao since 1980s, focuses on the phylogenetic relationship of medicinal plants and is thus nurtured by molecular phylogeny, chemotaxonomy and bioactivity studies. Phylogenomics can be integrated into the flow chart of drug discovery and development, and extend the field of pharmaphylogeny at the omic level, thus the concept of pharmacophylogenomics could be redefined. This review gives a brief analysis of the association and the distinguished feature of the pharmaphylogeny related terms, in the context of plant-based drug discovery and sustainable utilization of pharmaceutical resource.

OBJECTIVETo observe the efficacy of Chinese herbs for supplementing qi and activating blood circulation (CHSQABC) on patients with acute coronary syndrome (ACS) and type 2 diabetes mellitus (DM) after successful percutaneous coronary intervention (PCI).

METHODSIn this ChiCTR-TRC-00000021, a total of 281 ACS patients complicated with type 2 DM after successful PCI were randomly assigned to the Western medicine treatment group (the control group, treated by routine Western medicine treatment) and the combined treatment group (the treatment group, treated by CHSQABC + routine Western medicine treatment). Patients in the combined treatment group took Xinyue Capsule (2 pills each time, 3 times per day) and Compound Chuanxiong Capsule (2 pills each time, 3 times per day for half a year and 1-year follow-ups). Primary endpoints covered incidence of death, nonfatal myocardial infarction (MI), ischemia-driven revascularization, and secondary endpoints included stroke, heart failure, and rehospitalization for ACS. At the same time scores for blood stasis syndrome (BSS) and the incidence of angina pectoris were evaluated before treatment, at month 1, 3, 6, 9, and 12 after treatment.

RESULTSThe incidence of ischemia-driven revascularization was obviously less in the treatment group than in the control group (P < 0.05). No patient had nonfatal MI in the treatment group, while 5 patients in the control group had it. The incidence of non-fatal MI showed an obvious lowering tendency in the treatment group, but with no statistical difference when compared with that in the control group (P > 0.05). Four patients readmitted to hospital in the treatment group, while 12 patients readmitted. There existed obvious tendency in the treatment group, but with no statistical difference when compared with that in the control group (P > 0.05). The incidence of angina was significantly lower in the treatment group at month 6, 9, and 12 than that at month 1 , but it was lower in the control group at 9 months (P < 0.05). The incidence of angina was 15. 4% in the treatment group, obviously lower than that in the control group (26.2%, P < 0.05). Compared with before treatment, scores for BSS were obviously lowered in the treatment group at 1, 3, 6, 9, and 12 months of treatment and in the control group at 3, 6, 9, and 12 months of treatment (P < 0.05). It was obviously lower in the treatment group than in the control group at 3, 6, 9, and 12 months of treatment (P < 0.01).

CONCLUSIONAdministration of CHSQABC combined routine Western medicine treatment could reduce the event of revascularization and post-PCI recurrent angina, and improve scores for BSS of ACS patients complicated with DM after PCI.

The genus Fritillaria is a botanical source for various pharmaceutically active components, which have been commonly used in traditional Chinese medicine for thousands of years. Increasing interest in Fritillaria medicinal resources has led to additional discoveries of steroidal alkaloids, saponins, terpenoids, glycosides and many other compounds in various Fritillaria species, and to investigations on their chemotaxonomy, molecular phylogeny and pharmacology. In continuation of studies on Fritillaria pharmacophylogeny, the phytochemistry, chemotaxonomy, molecular biology and phylogeny of Fritillaria and their relevance to drug efficacy is reviewed. Literature searching is used to characterize the global scientific effort in the flexible technologies being applied. The interrelationship within Chinese Bei Mu species and between Chinese species, and species distributed outside of China, is clarified by the molecular phylogenetic inferences based on nuclear and chloroplast DNA sequences. The incongruence between chemotaxonomy and molecular phylogeny is revealed and discussed. It is essential to study more species for both the sustainable utilization of Fritillaria medicinal resources and for finding novel compounds with potential clinical utility. Systems biology and omics technologies will play an increasingly important role in future pharmaceutical research involving the bioactive compounds of Fritillaria.
