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.

BACKGROUND:Studies have shown that craniocerebral injury can promote the repair of sciatic nerve injury in rats, but its precise mechanism remains unclear.
OBJECTIVE:To further explore the action mechanism of craniocerebral injury on the repair of sciatic nerve injury using morphology and histology.
METHODS:Sixty specific-pathogen-free healthy male Sprague-Dawley rats were randomly divided into two groups. Rats with craniocerebral injury and sciatic nerve injury were considered as the experimental group. Rats with simple sciatic nerve injury were considered as the control group. Classical Feeney method was used in models of craniocerebral injury and SunderlandV sciatic nerve injury. At 8 and 12 weeks after modeling, sciatic nerve index was detected. Masson staining and NF200 immunofluorescence staining were used to observethe nerve regeneration atthe anstomotic site. Transmission electron microscope was used to observe the number of regenerative axons.
RESULTS AND CONCLUSION:At 8 and 12 weeks after modeling, compared with the control group, gait and sciatic nerve index recovered better in the experimental group. In the experimental group, Masson staining showed fewer nerve membrane colagen fibers, and the axon arranged neatly.NF200 immunohistochemistry showed that in the experimental group, the density of regenerated nerves was high, and nerveswere regularly distributed. Transmission electron microscopy showed that in the experimental group, regenerative axons were regularly arranged, colagen scar was less, and myelin layer arranged regularly. Results suggested that the craniocerebral injury in rats may promote the repair of peripheral nerve injury by reducing scar colagen in nerve endings.

BACKGROUND:Recovery of motor and sensory function from peripheral nerve injury is relatively slow and incomplete. It is a difficult problem for orthopedic surgeons that mainly leads to the decline in the quality of life in patients.
OBJECTIVE: To conclude the methods and corresponding outcomes in peripheral nerve regeneration by analyzing the new treatment means for peripheral nerve injury.
METHODS:PubMed, Wanfang, CNKI databases were retrieved for relevant articles using key words of “nerve injury, regeneration”, and then retrieval data were sorted and analyzed.
RESULTS AND CONCLUSION:In recent years, in-depth studies on peripheral nerve repair have been made in the folowing aspects: surgical mode, drug, cytokine, gene transfer and biomaterials as wel as traditional Chinese medicine. If the detect size is four times longer than the diameter of nerves, the nerve regeneration chamber can achieve good outcomes. The methods of restoring nerve continuity folowing nerve injury are developed from surgical anastomosis to photochemohistological method, thermal laser welding, plastic repair and other emerging technologies. Studies have found that plasminogen activator, nerve growth factor, neurotrophic factor, recombinant erythropoietin, human tissue kalikrein, B vitamins and their derivatives, herbal preparations, immunosuppressive agents al can promote nerve regeneration.

Objective To study the molecular mechanism of interleukin 25 (IL-25)expression in the lung of asthmatic rats.Methods The expressions of IL-25 mRNA and protein in the lungs were detected by Real-time PCR and ELISA,respectively.The levels of IL-25 mRNA and protein were detected by ovalbumin (OVA)in human bronchial epithelial cells.And the transcription factors that regulate IL-2 5 expression were explored through site prediction.Results The expressions of IL-25 mRNA and protein in the lung of OVA-induced asthma rats were significantly increased during animal experiments.Cell experiments showed that OVA could increase the expression of IL-2 5 in human bronchial epithelial cells in a dose-dependent manner,and OVA could upregulate the expression of transcription factor AP1.AP1 was found in the promoter region of IL-25 by site prediction.The AP1 inhibitor (T5224)significantly reduced the expression of IL-25 in OVA-induced human bronchial epithelial cells. Conclusion The molecular mechanism of IL-25 expression induced by OVA in asthma is related to the increase of transcription factor AP1 .

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 discuss the factors that affect the clinical application of sex therapy for erectile dysfunction (ED).
METHODSUrological researchers recommended free sex therapy to ED patients and their partners in the outpatient department and studied the factors affecting the patients of Medicaid their partnersology, acceptance of sex therapy by interview and observation.
RESULTSMany patients refused sex therapy. Only 11 pairs of volunteers underwent it, of whom 5 pairs gave up halfway, 1 pair were stopped by the therapist due to the breakup of their marriage, and merely 5 pairs accomplished the whole course. Among the 5 pairs of quitters, 2 pairs thought of their problem as organic and turned to drug therapy, 1 pair withdrew because the patient's girlfriend broke up with him, 1 pair gave up because they lived in another city too far away from the clinic, and the other pair discontinued because they could not spare the time from their work.
CONCLUSIONSMany factors affect the clinical application of sex therapy for ED in China. Apart from the shortage of qualified professional sex therapists, some factors from the patients and their partners are at work, such as stress of work, lack of time, home location, education background, relationship between the patient and his partner, attitude to sex therapy, and so on.

OBJECTIVETo evaluate the sex therapy for erectile dysfunction (ED).
METHODSWe recommended the sex therapy to ED patients and their partners (11 couples in all) in the outpatient department. Of the total number of volunteers, 2 males were accompanied by ejaculation disorder, another 2 with hyposexuality, and 1 female had vaginismus. The effect of the therapy was assessed and the problems with it analyzed by interviews with the subjects and the results of International Index of Erectile Function (IIEF) before and after the treatment.
RESULTSOf the 11 pairs of volunteers, 5 quitted halfway and 1 discontinued at the therapists' decision. The 5 couples who accomplished the whole therapy felt more satisfied with their sexual life and general relationship, with improved scores on all the items of IIEF, particularly on erectile function (EF), with the only exception of sexual desire (SD).
CONCLUSIONThe sex therapy is effective not only for ED but also for other accompanying sexual dysfunctions, the sexual dysfunctions of the patients' partners and the improvement of the general relationship of the couples.
