Objective To compare the results of three different registration methods in the kilovolt CBCT guided IMRT for nasopharyngeal cancer (NPC).Methods Total 560 CBCT images of 24 NPC patients who received kilovolt CBCT guided IMRT were analyzed off line.Three registration methods were used for alignment between CBCT and planning CT,including translational and rotational errors for bone and grey (BoneT + R,GreyT+ R),only translational errors for grey (GreyT).The registration results were analyzed by mean paired t-test respectively.Results With method BoneT+R,the translational errors on x,y and z axes were (-0.11 ± 1.35) mm,(0.40 ± 2.09) mm and (0.95 ± 1.56) mm and the rotational errors were 1.06° ±0.67°,0.01° ± 1.28° and 0.92° ± 1.00° respectively.With GreyT+R,the translational errors on x,y and z axes were (-0.02 ± 1.06) mm,(0.68 ± 1.92) mm and (0.81 ± 1.46) mm and the rotational errors were 0.85° ±0.61°,-0.05° ± 1.32° and 0.91° ±0.72° respectively.With GreyT,the translational errors on x,y and z axes were (0.58 ± 1.02),(0.52 ± 1.89) and (0.44 ± 1.43) mm.The results of compared mean t-test for different registration methods groups have significant difference (P =0.00-0.01) except for the rotational errors on y and z axes between BoneT+R and GreyT+R (P =0.05,0.62).Conclusions There have different alignment errors when different registration methods used for NPC kilovolt CBCT guided radiotherapy.If there have correct methods for rotation errors,GreyT+R registration method may be a better choice.In opposite,GreyT+R registration method would be used firstly to verify whether the rotational error ＞ 2°or 3°.If the rotational error ＞ 2°or 3°,the patient should be re-setup.If not,according to these alignment results,the GreyT method,manual method would be used to compensate the translational errors.

Objective: To understand the effects of remuneration incentive and their influences on job satis-faction in county public hospital. Methods: Stratified random sampling was adopted. Six county public hospitals in county level in Heilongjiang province were selected as the sample. Exploratory factor analysis was used to ana-lyze the remuneration incentives, descriptive statistical analysis and logistic regression analysis were used to ana-lyze the effects and their influences on work satisfaction. Results: remuneration incentives are divided into four dimensions that comprised a total of 16 items, which including direct material rewards, indirect material re-wards, occupational rewards and social rewards. The surgeon’s job satisfaction is higher than the physician, and is lower than the obstetrics and gynecology and pediatrics. Technician and nurses’ satisfaction is lower than the general practitioner. The medical staff who worked less than5 years has the lowest satisfaction. Authorized staff’s satisfaction is lower than off-staff. Direct material rewards and occupational rewards are related to job satisfac-tion. Conclusions:Material rewards were in low level, and non-economic incentive was insufficient. The salary incentive for highly educated talents should be strengthened.

Objective To explore the nursing method during bedside fibrobronehoseope to patients with inhalation injury and ensure the safety of the procedures. Methods 58 patients with inhalation injury with bed-side flbrobronehoseope treatment from 2005 to 2008 were retrospectively analyzed. Results 3 eases showed a-cute respiratory distress syndrome, 3 cases died of respiratory failure, 2 patients died of multiple organ failure,dyspnea, cough symptoms improved in others after sputum aspiration. Conclusions To master the preoperative,intraoperative, postoperative nursing methods during fibmbronehoscope can improve clinical efficacy.

Purpose　To explore the clinicopathological features of subcutaneous panniculitic T-cell lymphoma(SPTCL) and significances of genetic analysis in the diagnosis. Methods　Histopathology, immunohistochemitry and detection of clonal gene rearrangement by PCR were used in 3 cases of subcutaneous panniculitic T-cell lymphoma (SPTCL), which were originally diagnosed as relapsing nodular nonsuppurative panniculitis. Results　Three misdiagnostic cases were correctly redefined as subcutaneous panniculitic T-cell lymphoma, with immunophenotype of CD45+,CD45RO+, Mac387－,and clonal TCR-β gene rearrangement. Conclusions　Subcutaneous panniculitic T-cell lymphoma has distinctive clinicopathological features. Genetic analysis is an effective method for the diagnosis of SPTCL.

Objective To study the results of laparotomy and Cool-tip radiofrequency ablation to treat large liver tumors.Methods Laparotomy and Cool-tip radiofrequency ablation were carried out on 64 patients with large hepatic cancer.To destroy the tumor completely,for tumors of 3.0～4.0 cm in diameter,7 ablations were required; for 4.0～5.0 cm in diameter 15 ablations; for 5.0～6.0 cm in diameter 19 ablations; for 6.0～7.0 cm in diameter 40 ablations.Result The complete necrosis rate of laparotomy and radiofrequency ablation was 93.75％ (60/64).The short-term results were good.Conclusions Laparotomy and Cool-tip multipoint overlapping radiofrequency ablation for large liver tumors (tumor diameter＞3 cm) could result in a high complete necrosis rate and a low complication rate.It is a good radical treatment for unresectable and large liver cancer.

Objective:To assess the effect of rosiglitazone on inflammation in peritoneal dialysis patients. Methods:Fifty patients undergoing continuous ambulatory peritoneal dialysis were collected in our hospital. The treatment group was assigned to receive regular peritoneal dialysis and rosiglitazone 4mg once daily while the control group was received regular peritoneal dialysis for 12 weeks. Such serum examinations as fasting blood glucose (FBG), glycosylated hemoglobin A1c, haemoglobin, serum total cholesterol, high density lipoprotein cholesterol(HDL-C), low density lipoprotein cholesterol, triglycerides and high sensitivity C reactive protein (hs-CRP) were measured, tumor necrosis factorα(TNF-α) and interleukin-6 (IL-6) levels were measured by ELISA, and homeostasis model as-sessment of insulin resistance( HOMA-IR) was also evaluated before and after the treatment. Results:After the 12-week treatment by rosiglitazone, the levels of FPG, HOMA-IR, hs-CRP, TNF-αand IL-6 were declined significantly(P<0. 05), and the level of HDL-C was increased significantly(P<0. 05). Conclusion: Rosiglitazone shows significant anti-inflammatory, insulin resistance improve-ment and anti-lipidemic effects in peritoneal dialysis patients.

Objective To investigate the effects of improved end-to-end invagination pancreaticojejunostomy on the occurrence of pancreatic fistula after pancreaticoduodenectomy.Methods The clinical data of 396 patients who received pancreaticoduodenectomy at the Cancer Hospital of Shandong Province from January 2001 to January 2011 were retrospectively analyzed.All patients were divided into the improved group(235 patients)and traditional group(161 patients)according to different anastomotic methods.All the operations were done by the same surgical group,and the digestive tract was reconstructed by the Child method.Patients in the improved group received improved end-to-end invagination pancreaticojejunostomy,and patients in the traditional group received traditional end-to-end anastomosis.The volume of operative bleeding,operation time,incidence of pancreatic fistula and duration of hospital stay of the 2 groups were compared.All data were analyzed using the t test,chisquare test or Fisher exact probability.Results The operative blood loss,operation time and duration of hospital stay were(383 ±56)ml,(7.2 ± 1.0)hours,(21 ±3)days in the improved group,and(381 ±39)ml,(7.0 ± 0.5)hours,(22 ± 5)days in the traditional group,with no significant difference between the 2 groups(t =0.388,1.680,-1.835,P ＞ 0.05).No operative death was detected in the 2 groups,and the overall incidence of pancreatic fistula was 7.6％(30/396).The incidence of pancreatic fistula of the improved group was 0(0/235),which was significantly lower than 18.6％(30/161)of the traditional group(P ＜ 0.05).Patients complicated with pancreatic fistula in the traditional group were cured by drainage,somatostatin administration and parenteral nutrition.Conclusion Improved end-to-end invagination pancreaticojejunostomy can significantly reduce the incidence of pancreatic fistula after pancreaticoduodenectomy.
