Objective To compare the antalgic effects of ropivacaine in various doses on brachial plexus nerves. Methods 87 patients undergoing upper arm surgery were enrolled in this study. The patients were unpremed-itated. The patients were randomized to receive ropivacaine of 0.30,0.25 or 0.20% (group Ⅰ,Ⅱ and Ⅲ) with mor-phine of 0.1mg/ml and Lidocaine of 10mg/ml. In order to analygesia of brachial plexus nerves,the rejecting of load dose is firstly 10ml,the total dose is 10ml/24h interval every time,the antalgic time is about 50 hours. To compare the antalgic effects of ropivacaine in various doses based on standard of VAS. Based on standard of Bromage to assess the situation of motor neuron blocking. Results According to standard of VAS in 6,12,24 and 48 hours after underwent surgery, the group Ⅲ is more effective than group Ⅰ and group Ⅱ ; according to standard of Bromage, the group Ⅰ is more effective than group Ⅱ and group Ⅲ. it has no adverse reactions to patients. Condusion 0. 25% of ropiva-eaine with morphine of 0.1mg/ml and lidocaine of 10mg/ml have obtained good antalgic effects for patients after un-dergoing upper arm surgery,it is fit for applying in clinic.

Objective To study the related factors of stress of parents of children with intellectual disabilities and autism. Methods 45 parents of children with intellectual disabilities and 45 with autism were surveyed. Results and Conclusion The stress level was very high in the parents of both 2 kinds of children, especially in the parents with autism children (P<0.01). The stress level of parents of both 2 kinds of children correlated positively with the level of disability, and correlated negatively with the family income.

Objective To evaluate 18F-FDG hPET/CT in the diagnosis of postoperative recurrence and metastasis of colorectal cancer. Methods GE HAWKEYE coincidence SPECT was carried out in 81 colorectal cancer patients with suspected recurrence or metastasis after intravenous injection of 259 ~ 298 MBq (7-8 mCi) 18F-FDG. The acquired data were reconstructed using iterative algorithm and attenuation-corrected X-ray. The results were compared with the final diagnosis established by histological examination of resected specimens、and clinical follow-up. Results The sensitivity, specificity, positive predictive value (PPV)and negative predictive value(NPV)was 93% (57/61)、80% (16/20)、93% (57/61)、80% (16/20) for 18F-FDG hPET/CT respectively. For conventional CT the sensitivity, specificity, PPV and NPV was 67% (37/55)、73% (19/26)、84% (37/44)、51% (19/37) respectively; 18F-FDG hPET/CT detected 91 recurrent or metastatic lesions whereas only 46 lesions were detected by conventional CT in 65 patients. Conclusions 18 F-FDG hPET/CT has unique value in the diagnosis of recurrence and metastasis in postoperative colorectal cancer patients which was superior to conventional CT. Combined 18 F-FDG coincidence imaging with localizing CT improves the detection and localization of postoperative recurrence and/or metastasis in colorectal cancer patients.
