RESUMO

OBJECTIVE: To explore the manifestations of jingjin (sinews/fascia) lesions and summarize their distribution rules in the patients with neck-type cervical spondylosis so as to provide the evidences for the development of clinical diagnosis and treatment scheme of acupuncture for cervical spondylosis. METHODS: A total of 120 patients with neck-type cervical spondylosis were collected. The meridian diagnostic method was used to examine the upper back of each patient, the manifestation category of jingjin lesions, locations and the affected muscle regions of twelve meridians were recorded. RESULTS: (1) The punctate lesions of jingjin were detected in 15 regions, and the highest frequency of lesion occurred in the region from the inner upper corner of the scapula to Quyuan (SI 13) (113 cases, 94.2% of lesion frequency). The lesion frequency of 10 regions was ≥50.0%. The punctate lesions were mainly distributed in the muscle regions of hand-shaoyang (349 cases) and foot-taiyang (333 cases). (2) The linear lesions of jingjin were detected in 10 regions, and the highest frequency of lesion occurred in the region from the inner upper corner of the scapula to Quyuan (SI 13) (77 cases, 64.2% of lesion frequency). The lesion frequency of 2 regions was ≥50.0%. The linear lesions occurred mainly in the muscle region of foot-taiyang (251 cases). (3) Eight regions were examined to be the planar lesions of jingjin, and the highest frequency of lesion was found in the site of Jianjing (GB 21) (84 cases, 70.0% of lesion frequency). The lesion frequency of 3 regions was ≥50.0%. The muscle region of foot-taiyang (260 cases) was predominated in the planar lesions. (4) The distribution of all of the punctate, linear and planar lesions of jingjin was analyzed statistically. It was found that 25 regions were involved and those with the high lesion frequency were distributed in the area from the inner upper corner of the scapula to Quyuan (SI 13), the sites of Jianjing (GB 21) and Dazhui (GV 14), transverse processes of C3 to C5 and the area from the lateral border of the scapula to the teres minor, separately. The muscle regions of foot-taiyang, hand-shaoyang and hand-yangming were involved in various kinds of jingjin lesions. CONCLUSION: Jingjin lesions in patients with neck-type cervical spondylosis can be divided into three categories, namely, punctate, linear and planar lesions; of which, the punctate lesions are dominated. A majority of jingjin lesions is related to the muscle region of foot-taiyang, and the lesion frequency is higher compared with the lesions to the muscle regions of hand-shaoyang and hand-yangming. Jingjin lesions are commonly distributed in the area from the inner upper corner of the scapula to Quyuan (SI 13).

RESUMO

OBJECTIVE: To observe the effect of meridian sinew releasing technique on moxibustion sensation of heat-sensitive moxibustion in patients with knee osteoarthritis (KOA). METHODS: A total of 60 patients with KOA were randomly divided into an observation group and a control group, 30 cases each group. In the observation group, on the basis of the meridian sinew releasing technique, moxibustion sensation exploration method was applied at Dubi (ST 35) area on the affected side. In the control group, moxibustion sensation exploration method was applied at Dubi (ST 35) area on the affected side. The meridian sinew releasing technique was performed for 20 min each time, the moxibustion sensation exploration method was performed for 60 min each time, once a day for 3 days. The excitation rate, latency, duration time and intensity value of moxibustion sensation of heat-sensitive moxibustion were recorded on the 1st, 2nd and 3rd days of exploration in the two groups. RESULTS: The excitation rate on the 3rd day of exploration and total excitation rate in the observation group were higher than the control group (P<0.05). On the 1st, 2nd and 3rd days of exploration, the latency of moxibustion sensation of heat-sensitive moxibustion in the observation group was shorter than the control group (P<0.05), the duration time was longer than the control group (P<0.05), and the intensity value was higher than the control group (P<0.05). CONCLUSION: Meridian sinew releasing technique could improve the excitation rate of moxibustion sensation of heat-sensitive moxibustion in patients with KOA, shorten the latency, prolong the duration time, and improve the intensity value.

RESUMO

The aim of the present work is to isolate a series of triterpene derivatives with rhamnosyl linking acetyl groups from Glechoma longituba according to the structural characteristics of previously described triterpene saponins. The extract ion chromatography spectrum of the crude extract of G. longituba was detected and analyzed by HPLC-HR-ESI-MS to determine possible components, and these metabolites were traced and separated by combining high-resolution mass spectrometry and predicted liquid chromatography retention time. Three 11α, 12α-epoxypentacyclic oleanolic acid triterpene saponins (glechomanosides H-J) and one ursane triterpene aldehyde saponin with a C-28 aldehyde group were isolated from G. longituba. The structure of these compounds was confirmed by NMR and compared with those of previously characterized compounds. The strategy described in this report enables a rapid, reliable, and complete analysis of glycoside compounds containing different numbers of acetyl groups at different positions on the sugar.

RESUMO

In this study, antitumor activity and composition analysis of the core of Camellia osmantha fruit were investigated. The cores were extracted by 80% ethanol to obtain the crude extract (TF), which was successively distributed by different concentrations of ethanol with MCI resin to obtain three different parts (Frs 1 to 3). Cytotoxicity activities showed that TF, Fr-2, and Fr-3 exhibited good inhibition against T-24 with IC50 values of 6.7 ± 1.3, 6.9 ± 0.9, and 6.7 ± 1.7 µg/mL, respectively. Fr-3 has a strong inhibitory activity on T-24 cells, mainly due to effectively increasing the release of intracellular calcium ions and reactive oxygen species. In addition, Fr-3 can inhibit T-24 cells migration and invasion. Further composition analysis on Fr-3 was detected by LC-Q-TOFMS implying the main components to be ellagic acid and its derivatives.

RESUMO

The present study reports the phytochemical investigation of n-butanol-soluble extracts of Glechoma longituba. Five new oleanane-type triterpenoid saponins with an 11α, 12α-epoxy unit, named glechomanosides A - E, were isolated from the n-butanol soluble fraction of G. longituba. Their chemical structures were established using HRESIMS, IR, 1D NMR, and 2D NMR techniques. The compounds were all evaluated for their antithrombus activities by monitoring thrombin time (TT), prothrombin time (PT), activated partial thromboplastin time (APTT), and antiplatelet aggregation assays. These results suggest that G. longituba might be a candidate plant source of an interesting antithrombotic activity.

RESUMO

BACKGROUND: Non-Small-Cell Lung Cancer (NSCLC) is the most-frequent cause of cancer death, and novel chemotherapeutic drugs for treating NSCLC are urgently needed. 2α, 3α, 23-trihydroxy-13α, 27-cyclours-11-en-28-oic acid (euscaphic acid G) is a new hexacyclic triterpene acid isolated by our group from Glechoma longituba (Nakai) Kupr. However, the underlying mechanisms responsible for the anticancer effects of hexacyclic triterpene acid have not been elucidated. PURPOSE: In the present work, we evaluated growth inhibitory effect of the new isolated hexacyclic triterpene acid and explored the underlying molecular mechanisms. METHODS/STUDY DESIGNS: Herbs were extracted and constituents were purified by chromatographic separation, including silica gel, ODS, MCI, Sephadex LH-20 and preparative HPLC. The compound structures were elucidated by the use of UV, NMR and MS spectral data. The anticancer activity of euscaphic acid G was evaluated by MTT assay. Cell cycle, apoptosis, reactive oxygen species and mitochondrial membrane potential were determined by flow cytometry. To display the possible mechanism of euscaphic acid G on NCI-H460 cells, RT-PCR, immunofluorescence and Western blot analysis were carried out. RESULTS: A new hexacyclic triterpene acid, euscaphic acid G, together with fifteen known triterpenoids, was isolated from the aerial parts of G. longituba. Our results showed that euscaphic acid G exerted strong anti-proliferative activity against NCI-H460 cells in a concentration- and time-dependent manner. Flow cytometry demonstrated euscaphic acid G arrested the cell cycle at G1 phase, induced cellular apoptosis, accompanied by ROS generation and mitochondrial membrane potential reduction. Mechanistic studies revealed that euscaphic acid G treatment inhibited IKKα/ß phosphorylation and IκBα phosphorylation, which subsequently caused the blockage of NF-κB p65 phosphorylation and nuclear translocation. CONCLUSION: In conclusion, these results suggested that euscaphic acid G from G. longituba showed potential anticancer effects against lung cancer cells via inducing cell cycle arrest and apoptosis, at least partly, through NF-κB signaling pathways.

RESUMO

Matrix metalloproteinase 9 (MMP-9) is one of the structurally related zinc-dependent endopeptidases families and provides a new target for cancer therapy owing to its pivotal role in metastatic tumors. In this paper, fourteen lignans, including three novel lignans, named selamoellenin B-D (1-3), and eleven known lignan derivatives (4-14) were isolated from the plant of Selaginella moellendorffii. Among them, compound 3 is optically active, which was enantiomerically seperated to afford a pair of enantiomers, (-)-3 and (+)-3. Their structures were elucidated by extensive spectroscopic analyses. Their cytotoxic activities were evaluated against four human cancer cell lines. Among them, five compounds (4, 5, 6, 11 and 13) exhibited great potent cytotoxicity and their structure-activity relationships were also discussed. All compounds except for 3 lignan analogues with low cytotoxicity were selected for further in vitro enzyme inhibition, surface plasmon resonance (SPR), and molecular docking assays based on the MMPs target. The results shown that, compound 11 have the best inhibitory effect and can be considered as a potential drug candidate targeting at MMP-9 for cancer therapy.
