Objective:To summarize the experience of radiation oncology residency training programs in western coutries, and provide evidence to improve the present Phase-I Radiation Oncology Residency Training Programs in China.Methods:An electronic questionnaire-based survey was conducted among residents and staffs in 6 top cancer centers in China and 5 centers from Europe and North America to collect their feedback regarding the description and comparison of different programs.Results:A total of 70 responses and 4 papers explaining relevant training programs from 26 residents and 23 teachers in Chinese hopsitals and 20 residents and 1 teacher from Europe and North America were received. The Radiation Oncology Residency Training Programs in China were designed into 2 phases, and the results in the current study were involved with the first phase. Program designs were similar in the following aspects: goal, clinical practice-based training, rotation curriculum, interim and final assessment. However, the total timeframe in the investigated Chinese Phase-I programs was shorter than that in western hospitals (2 to 3 years vs. 4 to 5 years). Chinese programs covered major common diseases, whereas rotation design was performed based on each individual disease in western programs. In Chinese programs, the working hours were mainly 40-60 h every week. Although the working hours were commensurate with local workforce regulations, the residents from MSK program had an outstanding longer working time of 60-80 h every week and treated more patients compared with other programs. Conclusions:The investigated Phase-I Radiation Oncology Residency Training Programs in 6 top cancer centers in China share common features in goals, training modes and assessments with western programs. However, our programs have shorter timeframe and less detailed requirements in individual disease than the western programs.

Objective To evaluate the changes in the expression of artemin in skin around the inci-sion during remifentanil-induced hyperalgesia in the rats with incisional pain. Methods Thirty-two healthy male Sprague-Dawley rats, aged 10-12 weeks, weighing 250-280 g, were divided into 4 groups (n = 8 each) using a random number table: control group (group C), incisional pain group (group I), remifen-tanil group (group R) and incisional pain plus remifentanil group (group I+R). Remifentanil was intrave-nously infused for 60 min at a rate of 1 μg·kg-1 ·min-1 in group R. In group I, the model of incisional pain was established, and the equal volume of normal saline was infused for 60 min via the tail vein at the same time. In group I+R, the model of incisional pain was established, and remifentanil was infused for 60 min via the tail vein at a rate of 1 μg·kg-1 ·min-1 at the same time. The equal volume of normal saline was infused for 60 min via the tail vein in group C. Mechanical paw withdrawal threshold (MWT) and ther-mal paw withdrawal latency (TWL) were measured at 24 h before infusion of remifentanil or normal saline and 2, 6, 24 and 48 h after the end of infusion (T0-4 ). Rats were sacrificed following the last measurement of pain threshold, and ipsilateral plantar skin was removed for detection of the expression of artemin protein and mRNA (by fluorescent quantitative real-time polymerase chain reaction or Western blot). Results Compared with group C, MWT was significantly decreased and TWL was shorten at T1-4 , and the expression of artemin protein and mRNA in plantar skin was up-regulated in R, I and I+R groups (P<0. 01). Compared with R and I groups, MWT was significantly decreased and TWL was shorten at T1-4 , and the ex-pression of artemin protein and mRNA in plantar skin was up-regulated in group I+R (P<0. 01). Conclu-sion The peripheral mechanism by which remifentanil induces hyperalgesia may be related to up-regulated expression of artemin in skin around the incision in the rats with incisional pain.

Objective To evaluate the efficacy of different low-doses of nalmefene in preventing remifentanil-induced postoperative hyperalgesia. Methods One hundred American Society of Anesthesiolo-gist physical status Ⅰor Ⅱpatients, aged 20-64 yr, wih body mass index of 18-25 kg∕m2, scheduled for elective gynecological laparoscopic surgery under general anesthesia, were divided into 4 groups(n=25 each)using a random number table: control group(group C)and different doses of nalmefene groups (N1, N2 and N3 groups). In N1, N2 and N3 groups, nalmefene 02, 03 and 05 μg∕kg(diluted to 5 ml in normal saline)were intravenously injected, respectively, at 5 min before anesthesia induction, while the equal volume of normal saline was given in group C. Anesthesia was induced with midazolam 005 mg∕kg, sufentanil 03 μg∕kg, etomidate 03 mg∕kg and rocuronium 06 mg∕kg. The patients were me-chanically ventilated after tracheal intubation. Anesthesia was maintained by IV infusion of remifentanil 03 μg·kg-1·min-1and inhalation of 4%-6% desflurane, bispectral index value was maintained at 45-60, and muscle relaxation was maintained with intermittent IV boluses of rocuronium. After admission to postan-esthesia care unit, patient-controlled analgesia(PCA)was performed, and PCA solution contained sufen-tanil 1 μg∕ml in 100 ml of normal saline. PCA pump was programmed to deliver a 05 ml bolus dose with a lockout interval of 15 min and background infusion at 2 ml∕h. Numeric rating scale score was maintained <4. The time for remifentanil infusion was recorded. The consumption of sufentanil was recorded in 0-1, 1-3, 3-6, 6-12 and 12-24 h periods after surgery, and the occurrence of nausea, vomiting, tachycardia, hypertension and shivering was also recorded within 24 h after surgery. Results Compared with group C, the postoperative consumption of sufentanil was significantly reduced in 0-1 h and 1-3 h periods after sur-gery in group N1 and in 0-1, 1-3, 3-6 and 6-12 h periods after surgery in group N2, and the incidence of postoperative nausea was significantly decreased in N1, N2 and N3 groups(P<005). The consumption of sufentanil in 3-6 h period after surgery was significantly lower in group N2 than in group N1(P<005). Conclusion The optimal dose of nalmefene is 03 μg∕kg when used to prevent remifentanil-induced post-operative hyperalgesia.
