Antidiarrheal properties of different extracts of Chinese herbal medicine formula Bao-Xie-Ning / 中西医结合学报

<p><b>OBJECTIVE</b>Bao-Xie-Ning (BXN), a traditional Chinese herbal medicine (CHM) formula composed of Fructus Evodiae, Flos Caryophylli and Cortex Cinnamomi, and used for the treatment of infant diarrheal illness, was subject to systematic assessment for its putative multiple pharmacodynamic effects and pharmacological antidiarrheal mechanisms.</p><p><b>METHODS</b>High-performance liquid chromatography-diode array detector-electrospray ionization-mass spectrometric/mass spectrometry was developed and validated for identification and quantification of the main constituents in different extracts of BXN. Male Kunming mice weighing 20 to 25 g were used for detecting the antidiarrheal activity of the extracts. Ethanolic extract (EE), volatile oil extract (VOE), and aqueous extract (AE) of BXN were respectively subjected to pharmacodynamic and pharmacological comparison in assessing antidiarrheal effects with senna-induced diarrhea, castor oil-induced diarrhea, acetic acid-induced writhing assay, and isolated duodenum test.</p><p><b>RESULTS</b>The highest yields of three detected components of BXN, rutaecarpine, eugenol and cinnamaldehyde were observed in EE. EE showed the most remarkable antidiarrheal activity in dose-dependent and time-dependent manners in both senna- and castor oil-induced diarrhea models, and presented dose-dependent analgesic activity in acetic acid-induced algesthesia model. In addition, EE extract of BXN also exhibited strong antimobility action on the intestine and strongest depression on spontaneous contraction of isolated duodenum.</p><p><b>CONCLUSION</b>Ethanol extraction is an efficient method to extract the active constituents of BXN. BXN extract demonstrated multiple pharmacological activities affecting the main mechanisms of diarrhea, which validated BXN's usage in the comprehensive clinical treatment of diarrhea.</p>

Effect of human colon carcinoma-associated fibroblasts on biological behavior of colon carcinoma Lovo cells / 中华胃肠外科杂志

<p><b>OBJECTIVE</b>To investigate the effects of human colon carcinoma-associated fibroblasts (CAFs) on proliferation, adhesion, migration and invasion of colon carcinoma Lovo cells.</p><p><b>METHODS</b>The co-culture models among colon CAFs, NFs and Lovo cell were established by conditioned medium (CM) of human colon CAFs and colon normal fibroblasts (NFs). Lovo cells in the blank control group was treated with serum-free culture medium. The effects of human colon CAFs on proliferation, adhesion, migration and invasion of colon carcinoma Lovo cells were detected by cell proliferation assay, adhesion assay, migration assay and Transwell invasion assay.</p><p><b>RESULTS</b>After co-culture with colon CAFs, the absorbance (A) value of Lovo cells was (0.667±0.059) in 48 h and (0.709±0.030) in 72 h. The A value of Lovo cells adhesion to fibronectin was (0.588±0.067). The cell mobility rates were (35.2±8.7)% in 12 h and (64.6±7.1)% in 24 h. The number of invasive cell was (56.2±4.8). All the above parameters were increased compared with those in the blank control group and NFs group (all P<0.01).</p><p><b>CONCLUSION</b>Human colon CAFs can promote the proliferation, adhesion, migration and invasion of colon carcinoma Lovo cells.</p>

Clinical observation on colquhounia root tablet in treating lipid metabolism disturbance secondary to nephrotic syndrome / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To study the effect of Colquhounia root tablet (CRT) in treating nephrotic syndrome with sequential lipid metabolism disorder (NS-LMD).</p><p><b>METHODS</b>The 96 patients with NS-LMD were randomly divided into two groups, the 60 cases in the treated group treated with CRT and the 36 cases in the control group treated with hormone or cytotoxic medicine. The curative effect and the related indexes were determined before and after treatment.</p><p><b>RESULTS</b>After six months treatment, the general effective rate in the treated group was 88. 33%, which was markedly higher than that in the control group (69.44%, P < 0.05). The levels of the treated group in ameliorating lipid metabolism disorder and renal dysfunction were also higher than those in the control group (P < 0.05).</p><p><b>CONCLUSION</b>CRT could improve NS-LMD, improve renal function, eliminate urinary protein and increase plasma albumin. It is highly effective with low toxicity and safe.</p>
