Association of peripheral blood hypoxia-inducible factor-1α with metastasis of colorectal cancer / 南方医科大学学报

<p><b>OBJECTIVE</b>To explore the relationship between hypoxia-inducible factor-1α (HIF-1α) mRNA levels in the peripheral blood and the metastasis of colorectal cancer.</p><p><b>METHODS</b>HIF-1α mRNA in the peripheral blood was detected by RT-PCR in 40 patients with colorectal cancer and 20 healthy subjects.</p><p><b>RESULTS</b>Seventeen patients with colorectal cancer showed positivity for HIF-1α mRNA, showing a significantly higher positivity rate (42.5%) than the healthy subjects (P<0.05). The expression of HIF-1α mRNA is closely related to the staging of colorectal cancer (CRC).</p><p><b>CONCLUSION</b>HIF-1α mRNA may serve as a potential marker in the detection of metastasis of colorectal cancer.</p>

Application of intraoperative colon irrigation in primary resection and anastomosis of left colorectal cancer with intestinal obstruction / 南方医科大学学报

<p><b>OBJECTIVE</b>To study the application of intraoperative irrigation of the colon in primary resection and anastomosis of left colorectal cancer with intestinal obstruction.</p><p><b>METHODS</b>The clinical data were analyzed in 58 patients with left colon rectal cancer and intestinal obstruction undergoing intraoperative irrigation of the colon for primary anastomosis, and the results were compared with 58 patients receiving conventional primary tumor resection.</p><p><b>RESULTS</b>The mean intraoperative blood loss or postoperative hospital stay was comparable between the two groups, but the patients undergoing colon irrigation had significantly delays in the recovery of bowel movement.</p><p><b>CONCLUSION</b>With strict control of the surgery indication, intraoperative colon irrigation can be safe and feasible in primary resection and anastomosis of left colorectal cancer with intestinal obstruction.</p>

Traditional Chinese and Western medicine treatment of mycoplasmal pneumonia in children and the serum cytokine changes / 南方医科大学学报

<p><b>OBJECTIVE</b>To observe the therapeutic effect of traditional Chinese medicine (TCM) and Western medicine (WM) treatments on mycoplasmal pneumonia in children and the changes in the serum cytokines.</p><p><b>METHODS</b>Ninety children with mycoplasmal pneumonia were randomly divided into the treatment group and the control group. TCM was given orally and azithromycin at the daily dose of 10 mg/kg was administered intravenously in the treatment group. In the control group, only intravenous azithromycin was given. After a 7-day treatment, the response rate, time of symptom disappearance, and serum levels of IL-6, IL-8 and TNF-alpha were observed.</p><p><b>RESULTS</b>The total response rate was 93.33% in the treatment group and 73.33% in the control group, showing a significantly better therapeutic effect in the treatment group (P<0.05). The combined treatments also showed better effects in alleviating fever, coughing and rales (P<0.05), and resulted in more obvious reduction in the serum levels of cytokines (P<0.05).</p><p><b>CONCLUSION</b>Combined treatment with TCM and WM produce good therapeutic effects in children with mycoplasmal pneumonia.</p>
