RESUMEN
Acupoint autohemotherapy at bilateral Zusanli (ST36) and Xuehai (SP10) was used to treat a 26-year-old female patient who had suffered from recalcitrant atopic eczema (AE) for five years. The treatment was applied at a frequency of once per week for the first month, followed by a three-month period of once every other week. At the end of treatment, the patient's AE symptoms were entirely resolved, and by the end of a six-month follow-up her immunoglobulin E level had returned to the normal range. Further, there was no relapse of AE symptoms during the six-month follow-up. Therefore, we hypothesized that after the repeated treatments the local inflammatory reaction induced by autologous blood injection triggered a local immune response, followed by a systemic immune response after the repeated treatment, finally leading to the anti-inflammation and immunomodulation effects. This case suggests that acupoint autohemotherapy could be used as an effective complementary treatment for recalcitrant AE, especially in cases where other treatments have failed. Further comparative studies are needed to corroborate the value and mechanisms of this therapy.

Interplay between Cymbidium mosaic virus (CymMV)/Odontoglossum ringspot virus (ORSV) and its host plant Phalaenopsis equestris remain largely unknown, which led to deficiency of effective measures to control disease of P. equestris caused by infecting viruses. In this study, for the first time, we characterized viral small interfering RNAs (vsiRNAs) profiles in P. equestris co-infected with CymMV and ORSV through small RNA sequencing technology. CymMV and ORSV small interfering RNAs (siRNAs) demonstrated several general and specific/new characteristics. vsiRNAs, with A/U bias at the first nucleotide, were predominantly 21-nt long and they were derived predominantly (90%) from viral positive-strand RNA. 21-nt siRNA duplexes with 0-nt overhangs were the most abundant 21-nt duplexes, followed by 2-nt overhangs and then 1-nt overhangs 21-nt duplexes in infected P. equestris. Continuous but heterogeneous distribution and secondary structures prediction implied that vsiRNAs originate predominantly by direct Dicer-like enzymes cleavage of imperfect duplexes in the most folded regions of the positive strand of both viruses RNA molecular. Furthermore, we totally predicted 54 target genes by vsiRNAs with psRNATarget server, including disease/stress response-related genes, RNA interference core components, cytoskeleton-related genes, photosynthesis or energy supply related genes. Gene Ontology classification showed that a majority of the predicted targets were related to cellular components and cellular processes and performed a certain function. All target genes were down-regulated with different degree by vsiRNAs as shown by real-time reverse transcription polymerase chain reaction. Taken together, CymMV and ORSV siRNAs played important roles in interplay with P. equestris by down modulating the expression levels of endogenous genes in host plant.
