Objective To investigate the effects of comprehensive intervention on population death rate. Methods To analyze population crude death rate, cause-specific death rate, and compare the death rate in intervention group with that of control.Results The average crude death rate in communities of Changsha was 617 79 per 100 000, with 557 27 per 100 000 of standarized death rate. Cerebrovascular disease, cardiocascular disease, tumour, disease of respiratory system injury and intoxication were from the first rank to the fifth in order the death causes. The death rate in intervention group was lower than that of control group significantly, and the death rate of cerebrovascular disease and cardiocascular disease in intervention group were lower than that of control significantly.Conclusions Cerebrovascular disease and cardiocascular disease are the major causes of death. Intervention on risks factors of cardio- and cerebrovascular diseases can lower the death rate of cardio- and cerebrovascular diseases and the population death rate.

Objective To observe the effect combination of acupuncture and rehabilitation therapy early on motor function of patients with acute cerebral infarct.Methods 85 patients with acute cerebral infarct were randomly divided into treatment group (43 cases) and control group(42 cases).The all patients were treated by conventional medicine and rehabilition early. The cases of treatment group were treated by combination of acupuncture therapy simultaneously, All patients were evaluated before and after treatment respectively.Results The scores of Fugl-Meyer Assessment(FMA), Modified Barthel Index (MBI) and European Stroke Scale (ESS) of the patients in the treatment group and the control group were better than before treatment（P<0.05）, the effect of the patients in the treatment group were superior to the control group（P<0.05）. Conclusion Early rehabilitation combined with acupuncture therapy can improve motor function of patients with acute cerebral infarct.

Objective To compare the therapeutic effect of aerobic exercise training of different intensity on hypertension. Methods Sixty hypertensive patients were randomly allocated to 2 groups and treated with aerobic exercise training at 20% or 60% of maximal intensity. Not only were the relevanl parameters of exercise capacity measured by the use of treadmill exercise test,but also was ambulatory blood pressure monitored and the quality of life recorded before and after the therapy. Results There was nc significant difference of the decrement in any parameter of ambulatory blood pressure between the two groups ( P>0. 05).There was a significant difference of the increment of general health, vitality, emotion and mentality between the two groups after treatment with group A better than group B(P <0. 05). Conclusions Aerobic exercise training at 20% and 60% of the maximal intensity has similar ambulatory blood pressure, but the quality of life is significantly better after aerobic exercise training at 20% of the maximal intensity.

Background and purpose: Radiation therapy is still the most primary treatment of brain metastases, and prognosis is affected by many factors. The aim of this study was to identify the prognostic factors and to establish a prognostic index model in patients with brain metastases after whole-brain radiotherapy (WBRT). Methods: We reviewed the clinical date of 140 patients with brain metastases radiotherapy in our hospital from Jan. 2008 to Jul. 2011. The signiifcance of prognostic variables in the survival was resulted from both univariate analysis and multivariate analysis. The prognostic index (PI) was established based on Cox regression analysis and subgrouping values. It was assessed whether recursive partitioning analysis classes (RPA), basic score for brain metastases (BS-BM) and the graded prognostic assessment index (GPA) were related to prognosis. Results:The median survival time was 222 days. The univariate analysis showed that the independent prognostic factors were KPS performance status, number of brain metastases, presence of extracranial metastases, primary tumor status, radiation dose, hemoglobin. The multivariate analysis showed that KPS performance status (P=0.002, Wald=9.700), presence of extracranial metastases (P=0.018, Wald=5.604) and primary tumor status (P=0.001, Wald=10.212) were signiifcantly correlated with overall survival. RPA, BS-BM and GPA were closely related to their prognosis by Log-rank test. In predicting 3 months and 6 months of survival for patients, PI was better than other modes. Conclusion:Our data suggest that the 3 indexes RPA,BS-BM and GPA are valid prognostic index models, but PI model is better.

The prognosis of patients with brain metastases from non-small cell lung cance (NSCLC) is dismal,and whole brain radiation therapy(WBRT) cannot simultaneously control the extracranial lesions.Study results of Tyrosine kinase inhibitor(TKI) for brain metastases in patients with lung cancer are encouraging,and treatment efficacy is related to EGFR mutation status.The sensitizing theoretical foundation exists in utilizing erlotinib combined with WBRT for the treatment in brain metastases patients with lung cancer.Currently,a small clinical trial data shows that erlotinib combined with WBRT has better efficacy compared to erlotinib alone,and the toxicity can be tolerated.

Objective The hypoxic-ischemic(HI) cardio-cerebral damage caused by cardiac arrest in perioperative period is the main cause of acute and chronic disability in children patients.To investigate role of mitochondrial dysfunction in hypoxic-ischemic brain damage of mice.Methods The hypoxic-ischemic mice model was established by the bilateral carotid artery occlusion and hypoxia treatment.The neurobehavior of mice in HI model group,sham-operated group,and comparative group were evaluated within 48 hours after operation.After 48 hours,the mice were killed to evaluate the brain water content,mitochondria content,swelling,antioxidant capacity,and respiratory function.Results Within 0,24 hours after operation,the abnormal rate of the neurobehavior of HI model mice was 83.33％,which was significantly higher than comparative and sham-operated groups.The water content of right brain was significantly increased evidently compared to the other two groups (P ＜ 0.05).The content and swelling of mitochondria in brain were increased.The activity of superoxide dismutase (SOD),the glutathione (GSH) content,respiratory state 3 (ST3),and respiration control of rate (RCR) were significantly decreased; while the content of malondialdehyde (MDA) and ST4 were significantly increased (P ＜ 0.05).Conclusions The brain tissue showed different swelling,the mitochondrial function occurred disorder,which might play an important role in hypoxic-ischemic brain damage of mice.

Background and purpose: With the increase of aging population, elderly patients (age ≥70 years) with esophageal squamous cell carcinoma occurred more and more. However, few studies have focused on elderly esophageal squamous cell carcinoma patients. This study aimed to assess the outcomes and prognostic factors for elderly patients with esophageal squamous cell carcinoma treated after deifnitive chemoradiotherapy. Methods:We retrospectively analyzed 53 patients (age≥70 years) with esophageal squamous cell carcinoma and treated with deifnitive radiotherapy with or without chemotherapy from Fudan University Shanghai Cancer Center from Mar. 2009 to Dec. 2011. Results:Median age was 74 years. Twenty-nine patients underwent radiotherapy, 24 patients underwent radiochemotherapy. 1-, 2-, 3-, and 5- year survival was 62%, 44%, 33% and 19% respectively. Grade 2 and above acute radiation-induced esophageal toxicity and radiation pneumonitis occur rate was 6% and 9% respectively. No treatment-related deaths occurred and no patients experienced any grade 4 and above toxicities. Multivariate analysis identiifed treatment modality, tumor site and smoking history as independent prognostic factors for overall survival. Conclusion:Radiotherapy may be an acceptable treatment option for elderly patients with esophageal squamous cell carcinoma. In appropriately selected patients, concurrent chemotherapy could bring a better overall survival.

rate of diabetes and excess weight loss (EWL) in patients after treatment were 14.6％,80％ ± 15％ in the group A and 11.1％,60％ ± 10％ in the group B,respectively.There were statistically significant differences in body mass,BMI and EWL after treatment between the 2 groups (t=1.973,2.326,2.347,P＜0.05),and no statistically significant difference in remission rate of diabetes between the 2 groups (x2 =0.477,P＞0.05).(3) Influencing factors analysis of remission rate of diabetes in patients undergoing LRYGB:the results of univariate analysis showed that BMI,diabetes duration and LDL were factors affecting remission rate of diabetes in patients undergoing LRYGB,with statistically significant differences (x2=11.267,9.519,5.567,P＜0.05).The results of multivariate analysis showed that diabetes duration ＜ 10 years was an independent factor affecting good remission rate of diabetes in patients undergoing LRYGB,with statistically significant differences [OR=2.202,95％ confidence interval (CI):1.418-3.420,P＜0.05].(4) Influencing factors analysis of remission rate of diabetes in patients taking oral metformin:the results of univariate analysis showed that diabetes duration,GHb and LDL were factors affecting remission rate of diabetes in patients taking oral metformin,with statistically significant differences (x2 =6.306,7.758,4.652,P＜0.05).The results of multivariate analysis showed that GHb ＜ 15.0％ was an independent factor affecting good remission rate of diabetes in patients taking oral metformin,with statistically significant differences (OR=3.167,95％CI:1.586-6.325,P＜0.05).Conclusions LRYGB and oral metformin in the treatment of obese patients with type 2 diabetes mellitus are safe and effective,showing an equivalent remission rate of diabetes,and LRYGB had an advantage of weight loss.Diabetes duration ＜ 10 years and GHb ＜ 15.0％ are respectively independent factors affecting good remission rate of diabetes in patients undergoing LRYGB and taking oral metformin.

Objective To observe the iffectiveness of comprehensive rehabilitationinterventions on stroke patients with unilateral spatial neglect (USN). Methods A total of 245 cases if strijd were examined to diagnose USN. Of the 245 patients,86 cases were diagnosed as being with USN, and divided into a control group(n=43 cases) and a treatment group (n=43 cases) randomly. The control group was treated with Bobath and Rood techniques in addition to routine clinical medical interventions, while the treatment group was treated with a comprehensive rehabilitation protocol for USN in addition to the same interventions for the control group. Both groups were assessed with regard to motor, balance function, walking performance, and USN severity as well as the activities of daily living (ADL) performance. Results After 8 weeks of treatment,both groups improved, but there showed a significantly statistical difference between the 2 groups in terms of Fugl-Meyer motor function scores (P＜0.01), balance function scores (P＜0.01) Holden walding function classifications (P＜0.01), Barthel index(P＜0.001) and USN severity scores(P＜0.01). Conclusion Comprehensive USN rehabilitation intervention could improve motor, balance, walking functions and ADL performance and alleviate the USN severity in stroke patients with USN.

Objective To discuss the difference of cognitive function in patients of first-episode schizophrenia with and without metabolic syndrome.Methods Event related potential detection and Wechsler Memory Scale (WMS) was determined in 57 patients of first-episode schizophrenia with metabolic syndrome (research group) and 57 patients of first-episode schizophrenia without metabolic syndrome (control group),and the psychiatric symptom in two groups was assessed by the application of the positive and negative symptoms scale (PANSS).Results The memory quotient score was (78.51 ± 12.54) scores in research group,and (92.01 ± 17.49) scores in control group,and there was significant difference between two groups (t =-2.130,P=0.047).The short-term memory,instantaneous memory impairment in research group were lower than those in control group(t =2.151-3.054,P=0.007-0.046).The latency of P300 was (325.10 ±22.46) ms in research group and (284.60 ±22.46) ms in control group,and there was significant difference (t =3.454,P =0.003).The amplitude was (6.56 ± 1.61) μ V in research group and (9.78 ±1.73) μV in control group,and there was significant difference (t =-4.307,P =0.000).Conclusion The patients of first-episode schizophrenia with metabolism syndrome has more severe cognitive impairment than those without metabolism syndrome.
