The HANS group was treated by stimulating the acupoints of Jia Ji(T10-L3) and Ciliao(BL 32)with DC pulse of 100 Hz and 15-30 m A produced by a portable battery-powered Han's Acupoint Nerve Stimulator for 30 min. The PCIA group was intravenously infused Ondansetron(8 mg) for 5 min,then tramadol injection(1.5 mg/kg) was slowly dripped by using Baxter APⅡ electronic pump with50 m L tramadol(0.70%) + ondansetron(8 mg),background infusion 2 m L/h, PCA dose of 2 m L,lockout interval of 10 min. In PCEA group, women received intrathecal injection ropivacaine(3 mg) in L2-3, and epidural catheter was connected to Baxter APⅡ electronic pump, with 100 m L Ropivacaine(0.1%) and Sufentanil(50 ug), background infusion5 m L, Patient controlled analgesia(PCA) dose of 5m L, lockout interval of 10 min. The control group was not received analgesia. The visual analogue scale(VAS), stage and manner of labor, Apgar score of newborn, neonatal weights, oxytocin dosage,postpartum hemorrhage and side effects were monitored in all groups.RESULTS: The vital signs were all stable in the four analgesic groups. After analgesia, there was statistical difference in VAS score between HANS group and control group, between PCEA group and the control group, between PCIA group and control group. The analgesic effect in the PCEA group was significantly better than that of other two groups.The second stage of labor in the PCEA group was longer than the other three groups, showing significant difference between them. The Apgar score of newborn 1min after birth in the PCIA group was slightly lower than that of the other two groups,showing significant difference between them. The neonatal weights between four groups were not significantly different. The rate of cesarean sectionin the control group was significantly higher than that of the labor analgesia group, there was statistically difference in four groups. The number of PCIA group that used oxytocin was lower than that of other three groups. There was no significant difference in postpartum hemorrhage between four groups. The side effects of the PCEA group were itching, uroschesis and neonatal asphyxia and PCIA group were nausea and vomiting and neonatal asphyxia. However, fewer side effects were observed in the HANS group.CONCLUSION: The DC pulse produced by HANS may be a non-pharmacological alternative to labor pain with fewer side effects.展开更多

Methods: We first investigated the methylation status of the PCDH8 (Protocadherin-8) gene in 65 gastric cancer and detected aberrant promoter methylation in gastric cancers; and then analyzed he relationship between methylation status of the PCDH8 and clinicopathological status with SPSS 13.0 software. Results: We first investigated the methylation status of the PCDH8 (Protocadherin-8) gene in 65 gastric cancer and detected aberrant promoter methylation in 36 of 65 (55.4%) gastric cancers. There was no significant difference in the distribution of patients with methylation or unmethylation of PCDH8 in terms of age, sex, tumor size, distant metastasis, or TNM stage. Methylation of PCDH8 was significantly correlated to negative pathological lymph node metastasis (P=0.038) and tumor differentiation (P=0.01). These two factors were proved to be of prognostic importance. Conclusion: Methylated PCDH8 seems to have a trend for worse prognosis in gastric cancer. However, a further large series of tumor samples and a longer follow-up period are required to elucidate its potential role.展开更多
