Protecting action of acupuncture serum on calcium over-loaded neurons of the hippocampus in rats of ischemia-reperfusion / 中国针灸

<p><b>OBJECTIVE</b>To investigate the effect of acupuncture serum on Ca2+ content in the cultured nervous cells of hippocampus after ischemia-reperfusion, so as to probe into humoral factors in acupuncture treatment.</p><p><b>METHODS</b>The neurons of the hippocampus from the new born rats were cultured for 9-11 days. Fluorescein-molecular probe Fluo-3 AM was used for staining of intracellular Ca2+. Fluorescent levels in the nervous cells cultured with the serum of the normal rats or the rats given electroacupuncture at "Baihui" (GV 20), "Zusanli" (ST 36), "Quchi" (LI 11) and "Sanyinjiao" (SP 6) for 2 weeks were determined by using a laser confocal microscope.</p><p><b>RESULTS</b>After the normal serum was added, the intracellular Ca2+ fluorescent levels increased to 697 +/- 113 from 461 +/- 96, while after acupuncture serum was added, the Ca2+ fluorescent levels decreased to 584 +/- 103 from 673 +/- 108, indicating that after addition of acupuncture serum, the increased intracellular Ca2+ content could be decreased.</p><p><b>CONCLUSION</b>There are some active substances in acupuncture serum which can obviously decrease intracellular Ca2+ content after ischemia-reperfusion, so as to provide a direct evidence for role of humoral factor in acupuncture treatment.</p>

Acupuncture-serum decreases Ca2+ content in cultured rat myocardial cells / 中国针灸

<p><b>OBJECTIVE</b>To explore whether humoral factors play a role in the mechanisms of acupuncture.</p><p><b>METHODS</b>Primary culture of myocardial cells of neonatal rats were carried out. Five days later, they were labeled by fluorescent molecular probe Fluo-3AM. Changes of Ca2+ contents in the cultured myocardial cells after addition of the normal rat serum or acupuncture-serum of the rat who received acupuncture at "Neiguan" (PC 6) and Jianshi (PC 5), were dynamically observed by a confocal laser scanning microscopy.</p><p><b>RESULTS</b>After addition of normal serum of the rat, the intracellular Ca2+ level increased to a certain degree, and then gradually tended to stability, which was significantly decreased by addition of the acupuncture-serum (P < 0.01).</p><p><b>CONCLUSION</b>The serum of the rat who received acupuncture at acupoints can decrease the Ca2+ level in cultured myocardial cells, which provides a direct evidence for serum factors involving in acupuncture mechanism.</p>

Preliminary study on effect of acupuncture serum on Ca2+ content in cultured neurons of cerebral cortex / 中国针灸

<p><b>OBJECTIVE</b>To observe effect of serum of the rat after acupuncture on Ca2+ content of cultured nervous cells in vitro for exploring the role of humoral factors in acupuncture.</p><p><b>METHODS</b>Neurons of the cerebral cortex from the new born rats were taken and were cultured in a medium, 7 - 10 days later, fluorescein-molecular probe Fluo-3AM was used for staining of intracellular Ca2+. The intracellular Ca2+ levels in the nervous cells cultured with the serum of the normal rats or the rats given acupuncture at "Baihui" (GV 20), "Zusanli" (ST 36), "Quchi" (LI 11) and "Sanyinjiao" (SP 6) for 2 weeks were determined by using a laser confocal microscope.</p><p><b>RESULTS</b>After addition of the serum of.normal rats, the intracellular Ca2+ level increased and then gradually got stable, and when the acupuncture serum was added to the cultured medium, its level decreased to a certain extent.</p><p><b>CONCLUSION</b>Acupuncture serum can significantly decrease Ca2+ level in cultured cells of the cerebral cortex, which provides a direct evidence for involvement of humoral factors in the role of acupuncture.</p>

Gene expression differences between high and low metastatic cells of adenoid cystic carcinoma / 中华口腔医学杂志

<p><b>OBJECTIVE</b>To investigate the complex differences between high metastatic and low metastatic cells of the Adenoid cystic Carcinoma.</p><p><b>METHODS</b>Gene expression patterns were examined in high metastatic cell ACC-M strain and low metastatic ACC-2 strain with the method SSH (suppression subtractive hybridization).</p><p><b>RESULTS</b>although extensive similarity was noted between the expression profiles, twelve genes were highly expressed of, in low metastatic cell ACC-2 tester, compared with driver, high metastatic cell ACC-M. These genes were cysteine-rich angiogenic-inducer protein (cyr61), chromosome7 clone RP11-52501, G protein, was family member Iferritin heavy polypeptide I, jumping translocation breakpoint, eukaryotic translation elongation, folate receptor, ribosomal proteins L7a, S21, P0 and other two novel genes-ACC metastasis-associated RNH and ACC metastasis-associated suspected protein. GenBank accession number were AF522024 and AF522025 respectively.</p><p><b>CONCLUSIONS</b>the result suggests that the obtainment of the ability of metastasis is related to the low expression or mutation of these genes. These data provide insight into the extent of expression differences underlying metastasis-related genes that may prove useful as diagnostic or prognostic markers.</p>
