OBJECTIVETo explore the optimal intervention time of acupuncture and moxibustion in the treatment of peripheral facial paralysis.

METHODSTwo hundred and four cases of peripheral facial paralysis were collected in clinic for retrospective analysis. According to the time between the disease onset and the intervention of acupuncture and moxibustion, 3 groups (groups A, B and C) were divided. In group A, the treatment was given in 1 to 3 days after onset; in group B, the treatment was given in 4 to 7 days after onset; in group C the treatment was given in 8 to 10 days after onset. The treatment with acupuncture and moxibustion was applied according to the regular stages of disease in the three groups. At the acute stage, the less points and shallow puncture therapy combined with distal acupoints at the limbs were adopted on the affected side. At the stable stage, the more points and shallow puncture therapy were used on the affected side. At the recovery stage, the deep puncture or penetrating punctures was applied on the affected side. The curative effects was given once every day and the treatment of 10 days made one session. The curative effects were analyzed statistically at the end of three sessions of treatments separately.

RESULTSAt the end of the 1st session of treatment, the total effective rate was 58.8% (40/68) in group A, 69.7% (53/76) in group B and 46.6% (28/60) in group C. At the end of the 2nd session of treatment, the total effective rate was 85.3% (58/68), 90.8% (69/76) and 71.6% (43/60) in group A, B and C separately. At the end of 3rd session of treatment, the total effective rates were 89.7% (61/68), 97.4% (74/76) and 83.3% (50/60) in the three groups separately. The differences were significant statistically at the same session of treatment among three groups (all P<0.05), in which, the results in group B was the best, followed by group A and C in sequence.

CONCLUSIONthe best intervention time of acupuncture and moxibustion is in 4 to 7 days after onset of facial paralysis.

Four properties and five tastes are the core content of medicinal theory of Chinese materia medica (CMM), and it is important for modern study of CMM to elucidate the scientific connotation of five tastes based on the application of bionic technology. With the development of bionic technology, electronic nose and electronic tongue have become the objective method to determine the taste and smell in recent years. Based on the taste and odour connotation of five tastes of CMM, the working principle, research method, and identification of flavor substances in CMM of electronic nose and electronic tongue were summarized, and the progress on original variety, production place, growth period, storage life and processing technology of CMM were reviewed in this article. Combined with the practice of our research group on the characterization of medicinal properties, the basic research model of the definition and characterization of the five tastes of effective materials basis was proposed, which would provide a reference method for the medicinal research on five tastes of CMM.

BACKGROUND:In vitro isolation and purity technique of stem cells mostly depends on the identification of cell surface marker,such as monoclonal antibody adherent spreading method,flow cell sorting method and immunomagnetic beads sorting method,but the operation was complicated and the price was high.OBJECTIVE:To observe the biological characteristics of human amniotic fluid-derived embryonic mesenchymal stem cells,which were isolated and cultured using the two-step method.DESIGN,TIME AND SETTING:The opening study was conducted at the Stem Cell Research Room of Xinjiang Medical University from March 2008 to March 2009.MATERIALS:Totally 10 amniotic fluid specimens were obtained from pregnant women who underwent prenatal diagnosis following 16-22 weeks of gestation or voluntarily induced abortion.With ultrasonic guidance,amniocentesis was performed to collect 20-40 mL amniotic fluid.METHODS:Human amniotic fluid-derived embryonic mesenchymal stem cells were isolated and cultured using the two-step method.Amniotic fluid was first centrifuged and incubated till spindle-shape cells were seen,with the presence of flbroblast-tike cell colonies.Supematant was moved to a new 25 cm~2 culture flask for further culture till spindle-shape fibroblast-like mesenchymal stem cell colonies.When 70% confluence,cells were digested,and incubated in α-MEM,supplemented with basic fibroblast growth factor,served as the first passage.MAIN OUTCOME MEASURES:Morphological changes in human amniotic fluid-derived embryonic mesenchymal stem cells of primary culture and subculture were measured.Karyotype,cycle,growth curve and colony formation ability of human amniotic fluid-derived embryonic mesenchymal stem cells were measured.Surface antigen and cytokine were examined using flow cytometry,immunofluorescence and RT-PCR.RESULTS:Human amniotic fluid-derived embryonic mesenchymal stem cells were successfully isolated and subcultured.During metaphase,primarily cultured amniotic fluid cells presented scattered spindle cells and flbroblast-like mesenchymal stem cell colonies every 7 days.Passaged cells completely adhered in 12 hours.Following 1 or 2 days of latent period,cells proliferated rapidly.About 90% confluence was observed following 6 or 7 days of culture.Cell arranged regularly,showing whirlpool-shape,radiated shape.Cells were spindle-shape,with unclear boundary.Chromosome karyotype of human amniotic fluid-derived embryonic mesenchymal stem cells was normal diploid.Growth curve showed "S" shape,but the two-step method reached a peak at (6.1±0.5) days,which was significantly rapid compared with the one-step method (7.2±0.6) days (P=0.035).Flow cytometry analyses showed that P3 cells at S phase took up (14±2.3)% using the two-step method,which was more than the one-step method (9.0±1.4)% (P=0.031).Low-density human amniotic fluid-derived embryonic mesenchymal stem cells were incubated for 7 days prior to cells formed scattered cell colonies.However,colony forming efficiency using the two-step method (15.0±2.3)% were significantly more than the one-step method (10.0±1.8)% (P=0.021).Flow cytometry results showed that human amniotic fluid-derived embryonic mesenchymal stem cells expressed CD44,CD29 and CD105,but were negatively for CD45,CD34,HLA-DR.Immunofluorescence suggested that Oct-4-positive cells were observed in amniotic fluid.However,the proportion of Oct-4-positive cells using two-step method (1.2±0.3)% was significantly greater than the one-step method (0.9±0.2)% (P=0.041).RT-PCR suggested that human amniotic fluid-derived embryonic mesenchymal stem cells obtained using the two methods expressed Oct-4.CONCLUSION:Human multipotent mesenchymal stem cells are present in human amniotic fluid.The two-step culture protocol could be a kind of high performance and simple protocol which may not interfere with the normal prenatal diagnosis procedure.
