Effect of Sijunzi decoction on the proliferation of side population cells of human gastric cancer cell line / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To observe the proliferation changes of the side population of gastric cancer cell line SGC-7901 cells (SP), the non-side population (NSP) cells, and unsorted cells (Total) after intervened by Sijunzi Decoction (SD) containing serum.</p><p><b>METHODS</b>Sixteen pure bred New Zealand rabbits were equally divided into the normal control group, the low dose SD group (at the daily dose of 7 mL/kg), the middle dose SD group (at the daily dose of 14 mL/kg), and the high dose SD group (at the daily dose of 28 mL/kg) according to the random digit table. Rabbits' serum was extracted after equal volume of corresponding medication was given by gastrogavage twice daily for 2 consecutive weeks. The drug serum was identified using high performance liquid chromatography. SP cells of SGC-7901 were detected using flow cytometry, SP and NSP cells were screened. The proliferation curve of SP, NSP, and Total cells were detected with CCK-8 assay. Changes of their proliferation were also observed.</p><p><b>RESULTS</b>Ginsenoside Rg1, an effective ingredient in SD was detected in prepared drug serum. The proliferation of SGC-7901 SP cells was significantly higher than that of NSP cells and Total cells (P < 0.05). Drug serum on gastric cancer cell line SGC-7901 SP, NSP, and Total cells could inhibit their proliferation, but its inhibition on SP cells' proliferation was significantly lower than on NSP and Total cells (P < 0.05).</p><p><b>CONCLUSIONS</b>SD could significantly inhibit the proliferation of gastric cancer cell line SGC-7901 SP, NSP, and Total cells. But there exist obvious difference in the inhibition among the three groups.</p>

Effect of Chinese herbal therapy on T-lymphocytes of IgA nephropathy patients: a clinical observation / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To observe the effect of Chinese herbal therapy on T-lymphocyte subsets in patients with IgA nephropathy (IgAN).</p><p><b>METHODS</b>Totally 36 inpatients and outpatients at Department of Nephropathy, Xiyuan Hospital, China Academy of Chinese Medical Sciences, from June 2011 to June 2013 were recruited in the treatment group, while 20 volunteers were recruited as the healthy control group. Patients in the IgAN group only took Chinese herbal decoctions by syndrome typing for 3 months (except those accompanied with hypertension additionally took antihypertensive agents such as angiotensin-converting enzyme inhibitor and/or dihydropyridines calcium antagonist). No intervention was performed in the healthy control group. The values of Th1, Th2, and CD4+ CD25+ Treg, and red blood cell number in urine were detected using flow cytometry before and after treatment. 24 h urine protein was detected using inmmunoturbidimetry.</p><p><b>RESULTS</b>Compared with the healthy control group, the CD4+ CD25+ Treg level obviously decreased in the IgAN group, showing statistical difference (P < 0.01). In the IgAN group, Th1, 24 h urine protein, and urine red blood cell counts were obviously lower after treatment, showing statistical difference when compared with before treatment (all P < 0.05).</p><p><b>CONCLUSION</b>Chinese herbal therapy could reduce urine erythrocyte number and 24 h urine protein of IgAN patients, and down-regulating Th1 expression might be its mechanism.</p>

Regulatory effects of yiqi zishen granule on helper T-lymphocyte subsets in IgA nephropathy patients / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To study the pathogenesis of IgA nephropathy (IgAN) and the effect of Yiqi Zishen Granule (YZG) on the helper T-lymphocyte subsets Th1/Th2 in IgAN patients.</p><p><b>METHODS</b>Intracellular cytokines secreted by Th1/Th2 were measured using flow cytometry in 24 healthy subjects and 31 IgAN patients treated by YZG before and after treatment.</p><p><b>RESULTS</b>Level of interferon-gamma (IFN-gamma) was lower (P < 0.05) and levels of interleukin 4 (IL-4) and interleukin 10 (IL-10) were higher (P < 0.01) in the IgAN patients than those in the healthy controls, showing imbalance of Th1/Th2 in the IgAN patients. After YZG treatment, the level of IFN-gamma increased and IL-10 level decreased (P < 0.01).</p><p><b>CONCLUSION</b>Imbalance of Th1/Th2 exists in IgAN patients. YZG has a regulatory effect on imbalance of Th1/Th2 in IgAN patients.</p>
