Objective. Tetramethylpyrazine (TMP) is an alkaloid extracted from the root and stem of the traditional Chinese herbal medicine called Chuanxiong. The present study aims to study the effects of TMP on hypoxic respiratory depression in rats. Materials and methods. The effects of TMP on respiratory responses of rats induced by hypoxia were observed by diaphragm electromyogram (EMG) recording. The effects of TMP on the protein expression of FOS and acid sensing ion channel1a (ASIC1a) in the brainstem induced by hypoxia were investigated by immunohistochemistry. Results. The respiration of rats was first excited and then depressed during hypoxia treatment, while TMP pretreatment could significantly antagonize the respiratory depression induced by hypoxia P < 0.01 . Hypoxia obviously induced the protein expression of FOS P < 0.01 and ASIC1a P < 0.05 in the brainstem, which can be also significantly inhibited by TMP pretreatment. Conclusions. TMP has protective effects on hypoxic respiratory depression, and the mechanisms might be concerned with its downregulation of FOS and ASIC1a in the brainstem induced by hypoxia.

Objective.We evaluated the efficiency of traditional Chinese herbal medicine (a compound herbal formula for invigorating spleen) as a complementary and alternative therapy for gastric cancer patients with peritoneal metastasis.Methods.Between 2001 and 2012, 93 gastric cancer patients with peritoneal metastasis were enrolled in this study. The effect of traditional Chinese herbal medicine on their long-term outcome was investigated. Kaplan-Meier method was used to assess the difference in survival time, and Cox proportional hazards regression analysis was performed to identify independent prognostic factors.Result.First-line palliative chemotherapy plus traditional Chinese herbal medicine was performed in 47 patients and the other 46 patients received chemotherapy alone. The overall survival was different between patients with and without traditional Chinese herbal medicine (12.0 versus 10.5 months;P=0.046). According to the Cox proportional hazard model, first-line chemotherapy cycle (hazards ratio [HR] = 0.527; 95% CI = 0.323~0.860) and TCHM (hazards ratio [HR] = 0.644; 95% CI = 0.481~0.992) were selected as independent prognostic factors for survival.Conclusion.The results suggest that traditional Chinese herbal medicine could improve the prognosis of the gastric cancer patients with peritoneal metastasis.
