Objective To compare the diagnostic value of MRS acquired by body coil(BODY)and endorectal Coil(ERC)in the detection of prostate cancer.Methods MRI and 3D MRS were performed in 12 patients with prostate disease,in which 6 of them were proved to have prostate cancer and the other 6 noncancerous disease.Both BODY and ERC MRS were performed in 7 patients,and only BODY MRS was performed in the other 5 patients.All MRS data were quantitatively assessed with a per-sextant method.The metabolic ratio of(Choline+Creatine)/Citrate[(Cho+Cre)/Cit]was measured in each ROI.ROC analysis was carried out to assess and to compare the diagnostic value of BODY and ERC MRS in patients with prostate cancer with Wilcoxon test.Results (1)The ratios of(Cho+Cre)/Cit in the prostate cancer group(median 1.744,0.295 to 7.998)was statistically higher than that in the non-prostate cancer group (median 0.412,0.112 to 2.113)acquired by using BODY MRS(Z=-9.159,P＜0.01).(2)The ratios of(Cho+Cre)/Cit in the prostate cancer group(median 1.975,0.479 to 7.998)was statistically higher than that in the lion-prostate cancer group(median 0.400,0.104 to 2.232)acquired by using ERC MRS(Z=-9.200,P＜0.01).(3)The mean ratios of(Cho+Cre)/Cit in the prostate cancer group and in the non-prostate cancer group acquired by using both coils were not of statistically significant difference(P＞0.05).(4)ROC analysis for diagnosing prostate cancer showed no significant difference(P=0.851)between the areas under the curve of BODY and that of ERC MRS(Az=0.93 1 and 0.935 respectively).Conclusion The BODY MRS could provide comparable diagnostic efficacy to ERC MRS in patients with prostate cancer.

Objective To evaluate the intraoperative opioid?sparing effect of different duration transcutaneous electrical acupoint stimulation ( TEAS ) in video?assisted thoracoscopic lobectomy. Methods Seventy?five patients, aged 18-64 yr, weighing 40-96 kg, of ASA physical status Ⅰ or Ⅱ, scheduled for elective video?assisted thoracoscopic lobectomy under general anesthesia, were randomly divided into 3 groups (n=25 each) using a random number table: control group (group C), 30 min of stimulation before induction of anesthesia group ( group B) , and stimulation throughout surgery ( group T) . In group B, the patients received TEAS ( frequency 2∕100 Hz ) on acupoints Xinshu ( BL15 ) , Feishu (BL13), Neiguan (PC6), Hegu (LI4) on the operated side starting from 30 min before induction of anesthesia until the beginning of induction, and the intensity was the maximum current that could be tolerated. The intensity for Neiguan ( PC6) and Hegu ( LI4) was 6-12 mA, and for Xinshu ( BL15) and Feishu ( BL13 ) was 9-18 mA. In group T, the patients received TEAS on the four acupoints mentioned above starting from 30 min before induction of anesthesia until the end of surgery. The patients had the electrodes applied, but received no stimulation in group C. After anesthesia was induced with propofol?sufentanil?cisatracurium, double lumen endotracheal tube was inserted. Propofol was given by target?controlled infusion to maintain BIS value within the range of 40-60. Cisatracurium was infused continuously to facilitate muscle relaxation. The infusion rate of remifentanil was adjusted to maintain analgesia nociception index value within the range of 50-70. The intraoperative consumption of remifentanil ( the intraoperative consumption of sufentanil was converted to the consumption of remifentanil producing the equivalent effect by 1∶ 10) was recorded. Results Compared with group C, the intraoperative consumption of remifentanil was significantly decreased in B and T groups. The intraoperative consumption of remifentanil was significantly lower in group T than in group B. Conclusion TEAS on Xinshu ( BL15 ) , Feishu (BL13), Neiguan ( PC6) and Hegu acupoints throughout surgery and for 30 min before induction of anesthesia significantly reduces intraoperative opioid consumption in the patients undergoing video?assisted thoracoscopic lobectomy, while TEAS throughout surgery provides better effect.
