摘要:
Sceletorines A and B, two unique alkaloids, were isolated for the first time from the aerial parts of Mesembryanthemum tortuosum. Their structures were determined by the extensive spectroscopic methods and their absolute configuration was established with ECD calculations. Plausible biosynthetic pathways for 1 and 2 are proposed and a relationship to the previously assumed artifact, channaine is also addressed.

摘要:
目的 观察不同灸量隔姜灸对脾虚证大鼠胃组织丝裂原细胞外激酶(MEK)1/2和细胞外调节蛋白激酶(ERK)1/2表达的影响,探讨隔姜灸治疗脾虚证的可能作用机制及量效特征.方法 将75只SD大鼠按随机数字表法分为空白对照组、模型组、隔姜灸3壮组、隔姜灸6壮组、隔姜灸9壮组,每组15只.200%大黄浓缩液4 ℃灌胃制作脾虚证大鼠模型.造模成功后,隔姜灸组选取"足三里""中脘"予不同灸量治疗,连续8 d.HE染色镜下观察大鼠胃组织病理学改变,免疫组化检测大鼠胃组织MEK1/2及ERK1/2的蛋白表达.结果 与空白对照组比较,模型组大鼠胃黏膜损伤明显,可见较大的破损、脱落;与模型组比较,隔姜灸3壮组大鼠胃黏膜表面有部分脱落、破损情况改善,隔姜灸6壮组和隔姜灸9壮组大鼠胃黏膜表面较完整、脱落及破损明显改善.与空白对照组比较,模型组胃组织MEK1/2及ERK1/2蛋白表达明显升高(P<0.01);与模型组比较,隔姜灸各组胃组织MEK1/2及ERK1/2蛋白明显表达升高(P<0.01);与隔姜灸3壮组比较,隔姜灸6壮组和隔姜灸9壮组胃组织MEK1/2及ERK1/2蛋白表达明显升高(P<0.01),但二者作用效果相当,差异无统计学意义(P>0.05).结论 隔姜灸通过提高胃组织MEK1/2及ERK1/2的蛋白表达,激活MEK/ERK信号转导通路,进而促进脾虚证大鼠胃黏膜的修复.

摘要:
Objective: To observe the effects of different doses of ginger-partitioned moxibustion on serum trefoil factor 1 (TFF1) and mucin 5AC (MUC5AC) levels, as well as the expression of epidermal growth factor receptor (EGFR) in gastric mucosa of rats with spleen deficiency syndrome, therefore, to explore the possible mechanism and the dose-effect characteristics of ginger-partitioned moxibustion in spleen deficiency syndrome. Methods: Seventy-five SPF grade Sprague-Dawley (SD) rats were randomly divided into a blank control group (group A), a model group (group B), a 3 moxa-cone ginger-partitioned moxibustion group (group C1), a 6 moxa-cone ginger-partitioned moxibustion group (group C2) and a 9 moxa-cone ginger-partitioned moxibustion group (group C3) using random number table method, 15 rats in each group. Except group A, rats in the other groups received intragastric administration of 4 °C 200% concentrated Da Huang (Radix et Rhizoma Rhei) to prepare spleen deficiency syndrome model. After successful modeling, rats in group B received no treatment; rats in group C1, C2 and C3 were treated with 3, 6 and 9 moxa-cone ginger-partitioned moxibustion at Zusanli (ST 36) and Zhongwan (CV 12) respectively for 8 continuous days. The general symptom score of rats was observed. The serum levels of TFF1 and MUC5AC were detected by enzyme-linked immunosorbent assay (ELISA). The expression of EGFR protein in gastric mucosa was detected by immunohistochemistry. Results: After the treatment, compared with group A, the spleen deficiency symptom score was increased in group B, the levels of serum TFF1 and MUC5AC, the EGFR protein expression in gastric tissues of group C1, C2 and C3 were significantly increased (all P<0.01); compared with group B, the spleen deficiency scores were decreased in group C1, C2 and C3, and the serum levels of TFF1 and MUC5AC, as well as EGFR protein expression in gastric tissues were increased (all P<0.01). Compared with group C1, the spleen deficiency scores were decreased in group C2 and C3, the serum levels of TFF1 and MUC5AC, and the expression of EGFR protein in gastric tissues were increased (all P<0.01), however, there was no significant difference between group C2 and C3 (all P>0.05). The mechanism may be related to the increase of serum TFF1 and MUC5AC levels and activation of EGFR protein. Conclusion: Ginger-partitioned moxibustion can improve the symptoms, as well as promote the proliferation and repair of gastric mucosa in rats with spleen deficiency. The therapeutic efficacy of 6 or 9 moxa-cone ginger-partitioned moxibustion is better than that of 3 moxa-cone ginger-partitioned moxibustion, while the efficacies are equivalent between 6 and 9 moxa-cone ginger-partitioned moxibustion groups. © 2018, Shanghai Research Institute of Acupuncture and Meridian.

摘要:
Phytochemical investigation of the roots and rhizomes of Pileostegia viburnoides var. glabrescens led to the isolation and identification of 31 compounds (1-31), 25 of which (1-2, 4-7, 9-12, 15-18, 21-31) were isolated from the Pileostegia genus for the first time. 7α-Hydroxyfriedelan-3-one-26-ol-29-oic acid (1) is a new friedelane-Type triterpene. The structure of n-butyl-β-D-fructopyranoside (2) was determined by single-crystal X-ray diffraction. Compounds 4 and 12 displayed marginal cytotoxicity against the P388 murine leukemia cell line with IC50 values of 13.4 μM and 25.0 μM, respectively. Compound 23 exhibited marginal anti-inflammatory activity by the inhibition of lipopolysaccharide induced nitric oxide production in RAW 264.7 macrophage cells, with an IC50 value of 32.0 μM. Compounds 3, 8-10, 25, and 27 were phytotoxic to the dicot Lactuca sativa (lettuce) and/or the monocot Agrostis stolonifera (bentgrass).

摘要:
目前高校心理委员工作由于相关政策、体制不完善,培训系统体系不健全,出现心理委员专业知识不足、作用发挥不充分、与院系和心理咨询室联系也不紧密的现象。大部分心理委员对自己的职责不太清楚,普遍缺乏心理学基本知识。高校应为心理委员的工作营造良好的工作氛围,健全心理委员的选拔、考核和激励机制,完善心理委员工作的运行机制,加强心理学知识的培训。
