Objective To investigate the effect of common diseases by the Charlson weighted index of comorbidities(WIC) in predicting 1-year survival rate of older patients with rectum cancer.Methods Retrospective analyzed 160 patients with rectum cancer who were admitted in general surgery of Beijing Chaoyang Hospital Affiliated to Capital Medical University from Jun.2011 to May 2012.The patients were divided into two groups according to 1-year survival status:survival group (n =123) and death group (n =37).The data were recorded including age,gender,cancer diagnosis,underlying diseases,operation mode (laparoscopic or open) The WIC and the Acute physiology and chronic health Ⅱ (APACHE Ⅱ) score were calculated.Logistic regression analysis was used to determine the independent predictors for 1-year survival rate.Receiver operating characteristics(ROC) curve was used to evaluate the value of WIC in predicting 1-year survival rate.Results Of the 160 patients,123 cases survived,37 cases died at 1 year after treatment.WIC score and APACHE score in death group were (2.2 ± 1.3) and (11.5 ± 5.1),higher than those of survival group (1.3 ± 1.2,9.5 ± 4.3 ;P =0.021,0.014).Multivariate Logistic regression analysis indicated that age,mode of operation,WIC score and APACHE score were related to the 1-year survival status of patients with rectal cancer(OR(95％ CI):1.053 (1.018-1.178,1.021 (1.011-1.906),1.786 (1.203-2.235),1.019 (1.004-1.628).ROC curve area of forecasting of death of the WIC score,APACHE Ⅱ score and the combination of the two are 0.731,0.828,0.959.Conclusion The WIC scoring system can be a good evaluation method for 1-year survival rate in old patients with rectum cancer.

ObjectiveTo explore the prognosis and relationship between soluble differentiation antigen of cluster designation 14 (sCD14) and the injury severity score (ISS) of casualties with multiple injuries.Methods A total of 86 casualties with multiple injuries were enrolled from October 2009 to March 2010,and the severity of trauma of casualties were assessed in ISS score within the first 24 hours after accident,and the patients were divided into survival and non-survival groups as per the outcomes in 28 days after accident. Another 20 healthy subjects served as control group. In multiple injuries group,sCD14 concentrations were detected and APACHE Ⅱ scores were calculated on the 1st,3rd,5th and 7th days after accident.The related coefficient between sCD14 and ISS was calculated and then the values of sCD14 in predicting prognosis were analyzed by ROC curve. ResultsCompared with control group, sCD14 concentrations were obviously higher in casualties of multiple injuries group at all observation intervals ( P ＜0.01). Compared with survival group, casualties of non-survival group had more higher sCD14 concentrations and APACHE Ⅱ scores ( P ＜ 0.05 ).The sCD14 concentration was correlated with ISS and the related coefficient was 0.469 ( P ＜ 0.01 ). ROC curve analysis suggested sCD14 had values in predicting prognosis of casualties with multiple injuries and area under ROC curve was 0.820.Conclusions The concentration of sCD14 is correlated with ISS and can be used for predicting the prognosis of casualties with multiple injuries.

BACKGROUND: As a kind of unwounded biomagnetism technique, magnetoencephalography (MEG) relfects immediate information of cerebral function by using magnetic source imaging through recording changes of magnetic field of neurocytes under different functional status.OBJECTIVE: To investigate the practicability of magnetoencephalography (MEG) imaging in localizing sensory-motor cortex for brain tumour surgery in 36 patients.DESIGN: Observational study.SETTING: Department of Neurosurgery, Guangdong Provincial Hospital of Traditional Chinese Medicine.PARTICTPANTS: From Janury 2003 to April 2006, 36 patients (17 male and 19 female) with brain tumors selected from Deparment of Neurosurgery, Guangdong 999 Brain Hospital underwent surgery with MEG-guided neuronavigation in the region of the sensory and motor cortex. Ages of the patients ranged from 13 to 70 years. Among the 36 patients, 14 with gliomas (including 5 highly malignant gliomas), 19 with meningomas, 1 with spongy angioma and 2 with adenocarcinoma (due to the metastasis of brain tumor). All patients and relatives provided the confirmed consent and the experiment provided by the local ethics committee.METHODS: A 148-channel biomagnetometer (4-D Neuroimaging, USA) was used to determine motor and/or senory cortex with sampling rate 678.17 Hz, high-pass filter 1.0 Hz and bandwith 200 Hz. MRI images were acquired using a Philips Gyroscan Intera 1.5T MR tomography. And then, the functional maps were transfered to the neuronavigation system for the treatment of brain tumor. All patietns followed up by further consultation and telephone call in 2-26 months after operation.MAIN OUTCOME MEASURES : Operative outcome and prognosis.RESULTS: MEG demonstrated that the tumor lesion changed the sensory-motor cortex in various degrees for the 36 patients. Brain tumors were resected completely in 34 cases. At 2-26 months after surgery, neurological deficits fully recovered in 19 cases, unchanged in 15 cases and deteriorated in 2 cases.CONCLUSION: MEG was found to be practical and useful in localizing sensory-motor cortex and brain tumor. It is a valuable non-invasive method for presurgical planning in the treatment of brain tumors.
