RESUMEN
Daphnane-type diterpenenoids are the major biologically active constituents in the genus Daphne. We find that there are about 101 Daphnane-type diterpenes in this genus, most of those compounds show different degrees of inhibitory effect on various cancer cell. Some of them have been studied in depth and the potent molecular mechanisms might be associated with modulation of different cell-signaling pathways. In addition, some compounds of this type also can inhibit the synthesis of protein and DNA. Absolutely, the anti-tumor activity of Daphnane-type diterpenes is worthy of attention. Unfortunately, most of the current research on the activity of these compounds is focused on simple drug efficacy, and its in-depth mechanism research is far from enough. On the other point of view, there still exists wide growing space on the depth of these compounds.
RESUMEN
ABSTRACT Frontotemporal dementias are classically described as early onset dementias with personality and behavioral changes, however, late onset forms can also be found. Considering the paucity of information about late onset behavioral variant frontotemporal dementia and its challenging diagnosis, we present a case report of an 85-year-old woman with behavioral changes and slow progression to dementia who was first diagnosed as having bipolar disorder and then Alzheimer's disease. The Daphne scale provided a structured means to improve clinical diagnosis, also supported by characteristic features on MRI and SPECT, while CSF biomarkers ruled out atypical Alzheimer's disease.
RESUMO As demências frontotemporais são classicamente descritas como demências de início precoce com mudanças de personalidade e comportamento, porém as formas de início tardio também podem ser encontradas. Considerando a escassez de informações sobre a demência frontotemporal - variante comportamental de início tardio e o diagnóstico desafiador, apresentamos um relato de caso de uma mulher de 85 anos com alterações comportamentais e progressão lenta para demência que foi diagnosticada pela primeira vez com transtorno bipolar e, em seguida, doença de Alzheimer. A escala DAPHNE foi utilizada permitindo a estruturação das características clínicas, aumentando a precisão do diagnóstico clínico, apoiado por características em RM e SPECT, enquanto os biomarcadores no líquor descartaram a doença de Alzheimer.

To screen the toxic polar fractions of Daphne genkwa, compare the toxicity of D. genkwa on crypts epithelial cells IEC-6 before and after vinegar processing, and preliminarily investigate the mechanism of D. genkwa vinegar processing on toxicity reducing. The proliferation of IEC-6 cells was observed by MTT. The levels of superoxide dismutase (SOD), malondialdehyde (MDA), glutathione (GSH), lactate dehydrogenase (LDH), as well as the enzyme activity of Na⁺-K⁺-ATPase and Ca²⁺-Mg²⁺-ATPase were determined in IEC-6 cells to evaluate the oxidative damages degree of IEC-6 cells. The apoptosis and cell cycle were analyzed by Flow Cytometry. The results showed that the dichloromethane extraction was the toxic polar fraction of D. genkwa, and after vinegar processing, the toxicity of dichloromethane fraction was significantly reduced (<0.01). As compared with the blank control group, the dichloromethane fraction of D. genkwa can obviously decrease the levels of SOD, Na⁺-K⁺-ATPase, Ca²⁺-Mg²⁺-ATPase (<0.01) and content of GSH, but increase the level of LDH and MDA in cell supernatant (<0.01). Besides, it obviously increased the early and late apoptotic rate of IEC-6 cells, obviously decreased the proportion of G₁stage cells, increased the ratio of S stage cells and M stage cells (<0.01). After vinegar processing, as compared with D. genkwa groups of various doses, it can significantly increase the levels of SOD, Na⁺-K⁺-ATPase, Ca²⁺-Mg²⁺-ATPase (<0.01) and content of GSH, decrease the level of LDH, MDA(<0.01), significantly decrease the early and late apoptosis rate of IEC-6 cells (<0.01), increase the proportion of G₁stage cells, and decrease the ratio of S stage cells and M stage cells (<0.01). Vinegar processing can reduce the toxicity of dichloromethane fraction of D. genkwa, and its mechanism may be associated with improving the activity of antioxidant enzymes and permeability in IEC-6 cells, and decreasing the oxidative damage.

RESUMEN
The purpose of this article is to identify Daphne genkwa and its adulterants, Wikstroemia chamaedaphne, according to the morphological and microstructure characteristics of their stem and foliage. The root of D.genkwa was studied simultaneously. The results indicated that the crude drug and processed pieces of Genkwa Ramulus were mainly composed of stems and branches where obvious opposite petiole scars and branch marks were able to be seen on their nodes. Otherwise, foliage or peduncles generally couldn't be found. Moreover, the fine silver flocculent fibers could be observed in the bark of fracture surface. The adulterants were the plant segments which were composed of stems, foliage and peduncles with spikelet-pedicel scars. There existed microstructures differences between Genkwa Ramulus and its adulterants. In the former, single thick lignified phloem fibers were interspersed in the stem phloem of the transverse section with very thick wall and unicellular non-glandular hairs could be observed on the lower epidermis of foliage. Nevertheless, in the latter, there was no thick lignified phloem fibers in cross section of stem phloem, the outer wall of epidermal cells of foliage hadthick cuticles and no non-glandular hairs in lower epidermis of foliage. The results can be used for the identification and the quality standard of the crude drug and processed pieces of D.genkwa.The characteristics of the microstructures and the transverse section can be used to identify the radix D.genkwa.
RESUMEN
To establish HPLC-MS/MS method for simultaneous determination of daphnetin, daphnoretin, and daphneticin in rat plasma after oral and intravenous administration of Daphne giraldii extract, and then use them in the calculation of pharmacokinetic parameters. Six sprague-dawley rats received intragastric administration of D. giraldii extract (daphnetin, daphnoretin and daphneticin were 88.40, 3.24 and 4.28 mg•kg⁻¹, respectively). Their drug plasma concentration was determined by LC-MS/MS with schisandrin as an internal standard to draw plasma concentration-time curve. The pharmacokinetic parameters were calculated by Kinetica 4.4. The results showed that the linear range was 5-1 000 μg•L⁻¹ for daphnetin, daphnoretin and daphneticin, and the method ological test showed conformance to the requirements.The intraday and inter-day variable coefficients (RSD) were both less than 15.0%, indicating that both of legitimate precise and accuracy were consistent with the analysis requirements of biological samples. For daphnetin, the pharmacokinetic parameters Tmax, Cmax, AUC0-t, T1/2 and MRT were 4 h, 858.96 μg•L⁻¹, 10 566.4 μg•L⁻¹•h, 5.19 h and 9.43 h, respectively. For daphnoretin, the pharmacokinetic parameters Tmax, Cmax, AUC0-t, T1/2 and MRT were 2.92 h, 178.00 μg•L⁻¹, 905.89 μg•L⁻¹•h, 3.50 h and 6.95 h, respectively. For daphneticin, the pharmacokinetic parameters Tmax, Cmax, AUC0-t, T1/2 and MRT were 2 h, 36.67 μg•L⁻¹, 355.11 μg•L⁻¹•h, 4.95 h and 8.27 h, respectively. The LC-MS/MS analysis method established in this study was proved to be so accurate and sensitive that it can be applied to the pharmacokinetic study of daphnetin, daphnoretin and daphneticin.

RESUMEN
Objective: To investigate the analgesic and anti-inflammatory property and possible involvement of opioid receptors of ethyl acetate extract from aerial parts of Daphne mucronata (D. mucronata) in mice by formalin test. Methods: Single doses of 2.5, 5.0 and 10.0 mg/kg of body weight of ethyl acetate extract of D. mucronata were intraperitoneally administered to the mice 30 min before analgesic test. The anti-nociceptive effect of preparations was evaluated based on the formalin in mice. Results: The results indicated that the extract (2.5, 5.0 and 10.0 mg/kg) increased the pain threshold of mice and induced analgesia in both phases of formalin test. Like morphine sulfate (5.0 mg/kg, i.p.), the extract also showed more effective analgesic effect on the late phase of formalin test. Pre-treatment of animals with naloxone (5.0 mg/kg i.p.) did not inhibit the effects of the extract. Conclusions: Our findings suggest that D. mucronata contains potential analgesic and anti-inflammatory compounds which support its traditional use. Moreover, it seems that the analgesic and anti-inflammatory effects of the extract is mediated by non-opioid mechanisms. Further pharmacological studies are required to determine whether the analgesic mechanisms are actually responsible for such properties.
RESUMEN
OBJECTIVE:To study the liver damage mechanism in mice caused by the incompatibility of Daphne genkwa com-bined with Glycyrrhiza uralensis in aspect of liver transporter. METHODS:40 mice were equally randomized into a normal control (isometric normal saline)group,a group of G. uralensis [15 g(medicinal matierias)/kg],a group of D. genkwa [15 g(medicinal tatierias)/kg],a group of D. genkwa with G. uralensis in the ratio of 1∶1 [15 g(crude drug)/kg],a group of D. genkwa with G. uralensis in the ratio of 1∶3 [15 g(medicinal matierias)/kg](n=8). The mice were given the corresponding drug,ig,once a day for 7 consecutive days. HE staining was performed and then the pathomorphology of liver tissues were observed under the light mi-croscope,and calculation was made for pathological grading. Western blot method was employed to determine the protein expre-ssion of the transporter Ntcp protein in the livers of mice. The contents of total bile acids(TBA)in livers of mice were determined. RESULTS:Compared to the mice in the normal control group,those in the group of 1∶1 and 1∶3 demonstrated higher protein ex-pression of Ntcp. In the group of 1∶1,the mice with grade“+++”hepatocyte degeneration were more (8). The mice with grade“+++”and“++”hepatocyte degeneration in the groups of 1∶3 were more (2 and 8 respectively). CONCLUSIONS:D. genkwa combined with G. uralensis can induce liver damage in mice by a mechanism which may be related to the accumulation of a large amount of TBA in the liver as a result of the increase in the expression of Ntcp in mice.
RESUMEN
Herpes simplex virus (HSV) is a common causative agent of genital ulceration and can lead to subsequent neurological disease in some cases. Here, using a genital infection model, we tested the efficacy of vinegar-processed flos of Daphne genkwa (vp-genkwa) to modulate vaginal inflammation caused by HSV-1 infection. Our data revealed that treatment with optimal doses of vp-genkwa after, but not before, HSV-1 infection provided enhanced resistance against HSV-1 infection, as corroborated by reduced mortality and clinical signs. Consistent with these results, treatment with vp-genkwa after HSV-1 infection reduced viral replication in the vaginal tract. Furthermore, somewhat intriguingly, treatment of vp-genkwa after HSV-1 infection increased the frequency and absolute number of CD3-NK1.1+NKp46+ natural killer (NK) cells producing interferon (IFN)-gamma and granyzme B, which indicates that vp-genkwa treatment induces the activation of NK cells. Supportively, secreted IFN-gamma was detected at an increased level in vaginal lavages of mice treated with vp-genkwa after HSV-1 infection. These results indicate that enhanced resistance to HSV-1 infection by treatment with vp-genkwa is associated with NK cell activation. Therefore, our data provide a valuable insight into the use of vp-genkwa to control clinical severity in HSV infection through NK cell activation.

RESUMEN
Objective To elucidate the analgesic activity of the ethanol extracts from the root of Daphne genkwa (EERD). Methods The analgesic activity of EERD was evaluated by the effects on adjuvant-induced nociceptive response and paw swelling, the formation of PGE_2 and IL-1? in adjuvant arthritis (AA) rats, the activities of SOD and CAT, the levels of NO/iNOS in serum and brain tissue as well as by the effects on c-Fos protein expression in spinal cord of AA rats. Results EERD at used doses significantly delayed the adjuvant-induced nociceptive response and eased the paw swelling in AA rats. EERD also evidently inhibited the production of PGE_2 and IL-1?, and enhanced the activities of SOD and CAT in the tissue of paws being injected by adjuvant. Furthermore, it remarkably reduced the content of NO and inactivated the activity of iNOS in brain tissue of AA rats. In addition, EERD at used doses exhibited prominent inhibition on adjuvant-induced expression of c-Fos protein in the spinal cord of AA rats. Conclusion EERD is an effective agent for analgesia. The possible mechanisms for its analgesia might be the actions of inhibiting the production of PGE_2 and the release of IL-1?, reducing the activity of iNOS and hence the generation of NO in brain tissue, and blocking superoxidation through enhancing the activity of SOD and CAT.
