Objective To investigate the effects of parecoxib and morphine on remifentanil-induced postoperative hyperalgesia in patients undergoing orthopedic operation. Methods Sixty ASA Ⅰ or Ⅱ patients,aged 20-62 yr, weighing 45-100 kg, undergoing orthopedic surgery, were randomly divided into 3 groups ( n = 20 each). Anesthesia was induced with midazolam, propofol, remifentanil and rocuronium. The patients were mechanically ventilated after tracheal intubation. Group Ⅰ received iv injection of morphine 0.15 mg/kg, group Ⅱ received iv injection of parecoxib 20 mg and morphine 0.075 mg/kg and group Ⅲ received iv injection of parecoxib 40 mg and morphine 0.075 mg/kg. Anesthesia was maintained with infusion of propofol and remifentanil and intermittent iv boluses of vecuronium. The emergence time, consciousness recovery time, extubation time,incidence of agitation and shivering, and VRS score at 5 min after recovery of consciousness were recorded. Pain at rest and at movement was evaluated using VAS score at 1,2, 4, 8, 12 and 24 h (T1-6) after surgery and MAP andHR were recorded simultaneously. The incidence of nausea and vomiting during 24 h after surgery was also recorded. Blood samples were taken before induction of anesthesia, at the end of operation and 24 h after operation for determination of plasma concentrations of PGE2 and TNF-α. Results There was no significant difference in emergence time, consciousness recovery time, extubation time, VRS scores, MAP, HR, incidence of agitation,shivering, nausea and vomiting among the 3 groups. Compared with group Ⅰ , VAS scores at rest at T1-2 and at movement at T1-6 were significantly increased in group Ⅱ , while VAS scores at rest and at movement decreased at T1-5 in group Ⅲ (P＜0.05). VAS scores at rest at T1-6 and at movement at T1-5 were significantly lower in group Ⅲ than in group Ⅱ (P＜ 0.05). There was no significant difference in the plasma concentrations of PGE2 and TNF-α at different time points between group Ⅰ and Ⅱ (P＞0.05). The plasma concentrations of PGE2 and TNF-α were significantly lower at the end of surgery in group Ⅲ than in group Ⅰ and Ⅱ (P＜0.05). Conclusion Preoperative iv parecoxib 40 mg and morphine 0.075 mg/kg can reduce remifentanil-induced postoperative hyperalgesia in patients undergoing orthopedic operation, and the efficacy is better than that of morphine alone.

Objective To investigate the risks of operative contamination of surgical gear by exfoliated cancer in 78 patients who received surgery for hepatocellular carcinoma.Methods Surgical gear from 78 patients who were operated for primary hepatocellular carcinoma were divided into four groups:A.surgical instruments; B.surgeon gloves; C.gauze and gloves used for cleaning equipment; D.gauze and gauze pad used for cleaning operation area.Saline was used to soak the surgical gear followed by low speed centrifugation.The precipitate was stained and then observed for cancer cells.Results The positive rates of cancer cell on surgical gear were significantly associated with the TNM stage,tumor location,tumor size,and surgical approach.The positive rate of liver cancer cell on surgical gear in TNM stage Ⅲ was higher than TNM stage Ⅰ / Ⅱ (56.3％ vs 21.7％,P=0.002).The positive rate of cancer cell on surgical gear was significantly related to tumor size and location (P=0.006,P=0.001).The positive cancer cell detection rate of non-anatomical liver resection was significantly higher than anatomical resection (53.8 ％ vs 26.9 ％,P =0.019).The positive cancer cell detection rate was significantly associated with different types of surgical gear (P=0.008),in which group C showed the highest cancer cell detection rate.Conclusion The risks of cancer cell contamination of surgical gear were significantly associated with progression of hepatocellular carcinoma,tumor size,location and surgical approach,and also associated with the frequency in the use of surgical gear,the operation scope of contact and the nature of surgical gear.

Objective This study investigated a method to rapidly inactivate tumor cells on surgical instruments intraoperatively.Methods Tumor cells were collected by immersing and washing the surgical instruments in 37 ℃ saline.The precipitation was collected by low speed centrifugation and then was cultured to harvest the tumor cells.The tumor cells were immersed in saline and distilled water of different temperatures for different duration of time.Inverted microscopy was used to investigate the changes in morphology.Results After immersion in 55 ℃ distilled water for 60 seconds,the tumor cells were swollen,the cell membranes disappeared,the sizes of the nuclei were reduced,the chromatin was condensed,and some cells lysed and separated from each other.Additionally,these tumor cells floated in the culture medium and lacked any living cells adhering to the walls of the bottle.In the group of tumor cells treated with 55 ℃ saline for 60 seconds,there were no obvious morphological changes of the tumor cell or nucleus.Conclusion The intraoperative immersion of surgical instruments in 55 ℃ distilled water for 60 seconds could completely inactivate tumor cells.

Objective To investigate the relationship between positive peritoneal exfoliated cancer cells and the clinicopathological features of patients with hepatocellular carcinoma before any invasive treatment.Methods Of the 92 patients with hepatocellular carcinoma who underwent laparotomy,ascites fluid was collected in the patients with peritoneal ascites; and peritoneal lavage fluid was collected in those patients without peritoneal ascites.Then,shedded cancer cells in these fluid samples were detected.Results The positive rates of peritoneal cancer cells were associated with the TNM stage,tumor location and tumor size.The positive detection rate of cancer cells in TNM stage Ⅲ and Ⅳ was significantly higher than stage Ⅰ and Ⅱ (38.1％ vs 8.0％ ; P =0.0005).The positive detection rate was higher in tumors located closer to the surface (P =0.0 002),and with larger diameter (P =0.00 007).Conclusion Peritoneal cancer cells were significantly correlated with tumor stage,tumor location and size in hepatocellular carcinoma.
