The incidence of pancreatic carcinoma is increasing obviously in recent years with a serious threat to the people's life, and yet there is not a single treatment for obtaining satisfactory prognosis. At present, the radical resection is the primary method for resectable pancreatic carcinoma, together with radiotherapy can improve the surgical resection rate and reduce the dissemination of tumors. Intraoperative radiotherapy can alleviate the pain and increase the survival rate, but the role of postoperative radiotherapy and chemotherapy is still in controversial. There is a lot of advantages for regional chemotherapy theoretically, but lack of evidence in practice. Physical therapy and biological therapy in the treatment of pancreatic carcinoma have been recognized extensively. It is possible to change fundamentally the current status of treatment and to improve the long-term survival rates with the quality of life until establishing a comprehensive treatment system mainly depended on surgical resection with combination of radiotherapy, chemotherapy, physical and biological treatment. The interventional therapy has been significantly developed as an important palliative treatment during recent years.

Objective To investigate the effect of malignant tumor on neuromuscular block of cisatracurium. Methods Sixty ASA Ⅰ or Ⅱ patients with head and neck neoplasms (15 cases with benign tumor, 45 with malignant tumor), aged 18-64 yr, were randomly divided into 4 groups ( n = 15 each): Ⅰ benign tumor group (group B,3 × ED95 ); Ⅱ -Ⅳ different dose cisatracurium group (group C1 (2 × ED95 ), C2 (3 × ED95 ) and C3 (4 ×ED95)). Neuromuscular block was assessed with accelerograph F (TOF-watch SX). Single stimulation of ulnar nerve was used. Anesthesia was induced with TCI of propofol (target plasma concentration 3 μg/ml) and remifentanil (target effect-site concentration 3 ng/ml). Tracheal intubation was facilitated with cisatracurium 0.15 mg/kg in group B, and with cisatracurium 0.10, 0.15 and 0.20 mg/kg in group C1, C2 and C3 respectively. The onset time, clinical duration, time for recovery of T/Tc to 75 % and recovery index were recorded. Results The clinical duration, time for recovery of T/Tc to 75 % and recovery index were significantly longer in group C2 than in group B (P < 0.05). The onset time was significantly shorter, while the clinical duration and time for recovery of T/Tc to 75% were significantly longer in group C2 and C3 than in group C1 , and in group C3 than in group C2 ( P <0.05) .Conclusion The duration of action and recovery times of cisatracurium were prolonged in patients with malignant tumor.

The viability and life span of pollen were evaluated by TTC (2,3,5-triphenyl tetrazlium chloride) and the peroxidase solution, the stigma receptivity were estimated by benzidine-H2O2 method and the fruiting characteristics were investigated. The results showed that (1) Anoectochilus roxburghii and A. formosanus appeared the same up-and-down trend of the pollen viability, increased and then decreased. The storage temperature and storage time had significant impact on the pollen viability. With the extension of storage time, the pollen activity decreased. 4 degrees C refrigerator storage may be extended the pollen vitality. (2) The stigma had receptivity in 1st day and reached the highest level in the 4th day after blooming. A. roxburghii lost receptivity in the 8th day while A. formosanus lost receptivity in the 10th day after blooming. (3) The different pollination had significant impact on seed setting rate. The seed setting rate of artificial cross-pollination was higher than that of the artificial self-pollination. Collecting pollen in the 3rd day and carrying out artificial cross-pollination in the 4th day after blooming can significantly improve seed setting rate. The results provided technical assurance for A. roxburghii and A. formosanus breeding of new varieties and seed breeding.

Pluronic modified polyamidoamine (PAMAM) conjugate (PF127-PAMAM) was prepared and the inhibiting effect of MDR against MCF-7/ADR was investigated with doxorubicin (DOX) as model drug. 1H NMR and FTIR spectra showed that the conjugate was synthesized successfully. Element analysis accurately measured that 27.63% amino of per PAMAM was modified by pluronic (PAMAM : PF127, 1 : 35.37 mole ratio). PF127-PAMAM showed an increased size and a reduced zeta potential compared to PAMAM. PF127-PAMAM had lower hemolytic toxicity and cytotoxicity due to the reduced zeta potential and the protection of PF127. Each PF127-PAMAM molecular could load 19.58 DOX molecules, and the complex exhibited sustained and pH-sensitive release behavior. PF127-PAMAM/DOX exhibited weaker cytotoxicity than free DOX in MCF-7 cells; while the complex showed much stronger reverse effect of drug resistance in MCF-7/ADR cells, and resistance reversion index (RRI) was as high as 33.15.

Laparoscopic curative gastrectomy has been widely adopted because it is minimal invasiveness.The efficacy of laparoscopic gastrectomy is comparable to that of open gastrectomy for patients with early or advanced gastric cancer,but few studies of laparoscopic total gastrectomy combined with distal pancreatectomy and splenectomy for patients with advanced gastric cancer have been reported.Seven patients with advanced gastric cancer received laparoscopic total gastrectomy combined with distal pancreatectomy and splenectomy at the First Hospital of Jilin University from September 2010 to September 2011.The mean operation time,blood loss,postoperative hospital stay and the nunber of lymph nodes resected were (218 ± 24) minutes,(366 ± 174) ml,( 14.6 ± 2.8 ) days and 32 ± 15,respectively.Two patients were complicated by pancreatic juice leakage and were cured with drainage. No anastomotic leakage,abdominal bleeding or mortality was observed. With the development of techniques and equipments,laparoscopic total gastrectony combined with distal pancreatectomy and splenectomy is safe and feasible in selected patients.
