Objective To evaluate the epileptic focus localization value of MSI in patients with refractory epilepsy and encephalomalacia. Method MSI examination was proceeded in 11 patients with refractory epilepsy and encephalomalacia. Five of them were treated with gamma-knife; the others were treated with surgery. Results In the five patients treated with gamma-knife, the result was satisfied in 3 patients, one patient improved significantly, the other one useless. The distance between the encephalomalacia and the epileptic focus was 4cm in one patient; one patient′s encephalomalacia was located in right frontal-parietal lobe but the epileptic focus mainly located in right temporal lobe, only a little located around the encephalomalacia. Overall agreement among VEEG,ECoG and MEG (presence of concordant spikes with the same localization shown by three techniques) was obtained in three patients, the areas localized by ECoG were larger than VEEG and MSI in two patients. The localization was different in VEEG, MSI and ECoG in one patient, then he was given a resection of bilateral occipital epileptic focus. The results of patients treated with surgery were satisfied. Conclusion The MSI localization of epileptic focus in patients with refractory epilepsy and encephalomalacia is precise, and it can direct the advanced clinical treatment.

Objective To study the CBCT image registration of PTV enlarging distance and IMRT planning(CT-1) for patients with lung cancer,and evaluate their characters.Methods Ten patients with lung cancer were included in the study.Two sets image,before and after radiotherapy,were acquired every week.Then delineated the targeted volume and made the planning (CT-2) according the enlarging distance data.To comparize the parameters of DVH for lung and spinal cord,volumes and dose of PTV and NTCP with CT-1 and CT-2.The difference of two plan was analyzed by covariance analysis or Wilcoxson's z-test.Results The max,min and mean dose of PTV,the lung V5,V10,V20,V30,V50 were similar in both plans (P =0.242-0.663).There was superiority in CT-2 of PTV and lung's mean dose(P =0.049,0,035).The NTCP had the decent tendency followed by the increasing of lung Vs,V10,V20(P =0.146,0.053,0.000).Conclusions CBCT based image registration can reduce PTV,the mean dose of lung,NTCP,and increase PTV dose.This provides a tool for exploring acurate radiotherapy strategies.

BACKGROUND:Previous studies have found that cholecystokinin octapeptide (CCK-8) can promote the regeneration after sciatic nerve injury in rats, but the exact mechanism remains unclear.
OBJECTIVE:To screen effective indicators and analyze the mechanism of CCK-8 promoting sciatic nerve regeneration from the perspective of nerve growth factor and nerve regeneration microenvironment.
METHODS:Healthy Sprague-Dawley rats, for the preparation of unilateral sciatic nerve transection injury model, were randomly divided into two groups. In the CCK-8 group, the animal model received intraperitoneal injection of CCK-8 (8 nmol/kg) for consecutive 7 days, while the control group was injected with equal volume of normal saline. The nerve growth factor expression, inducible nitric oxide synthase in the spinal cord, serum superoxide dismutase activity and malondialdehyde concentration, as wel as apoptotic cel s in spinal cord were al detected.
RESULTS AND CONCLUSION:In the CCK-8 group, nerve growth factor expression was higher than that in the control group (P<0.01), while inducible nitric oxide synthase and the number of apoptotic cel s were lower (P<0.01), serum superoxide dismutase activity was higher but malondialdehyde concentrations was lower (P<0.01, 0.05). The mechanisms of CCK-8 promoting sciatic nerve regeneration include protecting neurons, anti-apoptosis, inhibiting inflammatory response, anti-NO and anti-oxidation, reducing malondialdehyde, and al eviating free radical damage, as wel as stimulating nerve growth factor expression and release.

Objective To investigate the status of life quality in the elderly in Shanxi Province Changzhi City, and to analyze its influencing factors. Methods The quality of life, activities of daily living and status of community services were measured simultaneously by 36-Item Short Form Health Survey (SF-36). Activities of Daily Living Scale, Community Healthy Needs Scale and survey results were used and analyzed using t-test, correlation and stepwise regression analysis. Results According to the criterion of life quality in the elderly which were proposed by Zhang Lei, the quality of life in the elderly scored 72. 1-117.0, reached 98.5%. The quality of life in the elderly was impacted by the ability of caring oneself, marital status, degree of culture, economic situation and so on. The demand rate for health guidance and periodic physical examination was higher. Conclusions The quality of life in the elderly is at a medium level. There is a wide gap between the demand of community healthy services and the utilization of community healthy services.

Objective To investigate the quality of life of elderly caregivers and its factors. Methods Elderly caregivers living in Changzhi City were enrolled in this study. 36-item short-form (SF-36) health survey and Activity of Daily Living Scale ( ADL) were used as study tools. The data was analyzed by statistical description,t test or multiple regression. Results Those with score of quality of life reaching 72. 1 to 117. 0 accounted for 98. 8%. The total score and score of eight dimensions of SF-36 showed statistically significant difference between different daily living activity groups ( P < 0.05) . The state of health and self-care ability of the elderly imposed a major impact on eight dimensions of SF-36. Age, sex, level of education, marital status and wage had different impact on each dimension of SF-36. Conclusion The quality of life of elderly caregivers is at a medium level. The main factors of quality of live of elderly caregiver are their state of health and self-care ability of the elderly.

Objective To examine the clinical effect of simultaneous intervention for heart and lung on chronic obstructive pulmonary disease (COPD) of stationary phase combined with stable angina pectoris with Qi deficiencyblood stasis-phlegm blockade syndrome.Methods Ninety-six COPD stationary phase combined with stable angina pectoris patients with Qi deficiency-blood stasis-phlegm blockade syndrome were randomized into control group,Juhong [Exocarpium Citri Rubrum] tablet group,the Tongxinluo (通心络) group and the Ju&Tong group,24 cases in each group.The control group was given western medicine routine therapy.In addition to the treatment of the control group,Juhong tablet 3.6 g was given to the Juhong tablet group orally,twice each day;Tongxinluo capsule 1.04 g was given to the Tongxinluo group orally,three times each day;Juhong tablet and Tongxinluo capsule were given to the Ju&Tong group.Each group was treated for 8 weeks.The following intems were compared before and after treatment including the scores of cough,cough up phlegm,dyspnea and St.George's Respiratory Questionnaire (SGRQ),anginal attacks,durante dolors,nitroglycerin consumption,pulmonary function [including forced expiratory volume in one second (FEV1) and forced vital capacity (FVC)],as well as the levels of serum C reactive protein (CRP),interleukin 1β (IL-1β) and interleukin 10 (IL-10).Results After treatment,the scores of cough,cough up phlegm,dyspnea and SGRQ decreased in the Juhong tablet group,the Tongxinluo group and the Ju&Tong group.FEV1 and FVC increased.Anginal attacks,durante dolors,nitroglycerin consumption,as well as the levels of serum CRP,IL-1 βand IL-10 decreased.Moreover,the effect of certain indexes in the Ju&Tong group was superior to those in the Juhong tablet group and the Tongxinluo group (P ＜ 0.05 or P ＜ 0.01).Conclusion Simultaneous intervention for heart and lung might improve clinical symptoms and pulmonary function of COPD stationary phase combined with stable angina pectoris with Qi deficiency-blood stasis-phlegm blockade syndrome patients.Inhibiting chronic persistent inflammation might be one of the important mechanisms.
