Objective To study the effects of community nursing interventions on stroke patients with attention disorders.Methods A total of 60 stroke patients fulfilling eligibility were divided randomly into two groups.Their data were collected between December 2010 and February 2012.The intervention group was treated by community nurses while the control group trained by family members.Attention was assessed by simple reaction time (SRT) and number cancellation test (NCT).Modified Barthel index was used to assess the activities of daily living (ADL).Both groups were evaluated before and after a 2-month intervention.Results Before treatment,the control group had(0.71 ± 0.25),(662.8 ± 152.7) and(31 ±8)scores at SRT,NCT and MBI respectively.And the intervention group yielded(0.69 ± 0.19),(652.7 ±131.0) and (30 ± 8)scores at SRT,NCT and MBI respectively.There were no significant differences in average value of SRT,NCT and MBI between training and control groups at pre-treatment (P ＞ 0.05).After 2 months,the control group had (0.68 ± 0.20),(637.4 ± 151.7) and (33 ± 8) scores at SRT,NCT and MBI respectively.And the intervention group yielded (0.56 ± 0.16),(540.3 ± 125.9) and(37 ± 8) scores at SRT,NCT and MBI respectively.Very significant difference existed in attention scale scores at Month 2 (P ＜ 0.01) and the difference in ADL scale scores was also significant (P ＜ 0.05).Conclusion For stroke patients with attention disorders,strengthening community nursing interventions may help to improve attention and boost activity of daily living.

Objective To explore the value of preoperative spleen-liver volume ratio (SLVR) for predicting recurrence of primary liver cancer after hepatectomy.Methods Clinical data of 86 cases of hepatocellular carcinoma undergoing hepatectomy were analyzed retrospectively from January 2009 to December 2014.According to the preoperative SLVR,these patients were divided into two groups:SLVR ＜ 0.8 group (low SLVR group) and SLVR≥0.8 group (high SLVR group).Patients were followed-up until June 2015.Cox ratio risk pattern analysis was used for the recurrent correlative factors.Results The 1-,3-,and 5-year survival rates were 95.5％,88.6％,and 81.8％ in the low SLVR group,and 73.8％,47.6％,and 40.5％ in the high SLVR group,respectively.The difference were statistically significant between two groups (P ＜0.05).Cox regression analysis revealed that SLVR≥0.8,AFP-L3％ ≥10％,the maximum diameter of the tumor ＞ 5 cm,and hepatic or portal vein tumor thrombus were independent predictors of poor disease-free survival after hepatectomy for hepatocellular carcinomas (P ＜ 0.05).Conclusions Preoperative SLVR≥0.8 is an independent adverse predictor of poor disease-free survival.

Recepteur d′origine Nantais(RON),a tyrosine kinase receptor ,is a growth factor receptor belonging to the proto-oncogene met family and has been proved to display abnormal expres?sion in many types of tumors. The RON receptor is activated by binding to the ligand macrophage stim?ulating protein,overexpression of the receptor,variants of the proto-oncogene and by point mutations of the kinase region. The downstream transduction of RON by mitogen-activated protein kinases and phosphoinositide3-kinase signaling pathways can help regulate the proliferation,apoptosis,migration and invasion of tumor cells. A better understanding of the mechanisms and related signaling pathways of RON activation in tumor progress and development will provide more information for the RON-based target therapy.

Drug delivery system targeting immune system plays an important role in the treatment of inflammatory diseases.Drug delivery system targeting immune system could target immune cells or immune organs.It could be divided into active targeting mediated by the interaction of ligand-receptor or antigen-antibody and passive targe-ting mediated by pH;particles and so on.This review summarizes new progress for drug delivery system targeting immune system;which provides a theoretical reference for designing the safe and effective drug delivery system and providing efficient and safe treatment for inflammatory diseases.

Objective To study the impact of the number of functional natural teeth (FNT) and different oral restoration behaviors on well-being of the elderly.Methods The elderly residents of Guangzhou Haizhu District were acted as respondent,WHO-5 Scale was the measurement instrument of well-being.Analysis of covariance was used to correct confounding factors and analyze the corrected data,and then it was compared by LSD Test.Resuits (1) The results of analysis of covariance showed that,average scores on WHO-5 Scale were not all the same among different groups which were divided by different number of FNT or different oral restoration behaviors (Respectively:F=21.547,P＜0.001 ; F=141.219,P＜0.001).(2) The results of LSD Test showed that,although there were no statistical differences in corrected average scores between group with 5-9 FNT and group with 10-14 FNT (LSD-t=-0.536,P=0.593),differences had statistical senses between other groups(P＜0.01).All scores were ordered from the least to the most number of FNT,and they were (11.786±5.270),(15.724±4.036),(15.934±3.957),(18.941±2.616) and (23.390±6.951) respectively.It also showed that,there were no statistical differences in corrected average scores between the perfect oral restoration behavior group,the imperfect oral restoration behavior group and the no oral restoration behavior group(respectively:(23.056±4.772),(20.647±2.660),(14.872±7.313) ; P＜0.01).Statistical differences were also found in corrected average scores between the imperfect oral restoration behavior group and the abnormal oral restoration behavior group (respectively:(20.647 ±2.660),(14.565±2.914);LSD-t=13.108,P＜0.01).No statistical differences were found in corrected average scores between the no oral restoration behavior group and the abnormal oral restoration behavior group(respectively:(14.872±7.313),(14.565±2.914) ; LSD-t=-0.696,P＜0.01).The differences in corrected average scores between the needless oral restoration behavior group and the perfect oral restoration behavior group also showed no statistical significance (respectively:(22.848± 8.068),(23.056± 4.772) ; LSD-t =-0.340,P =0.734).Conclusion Well-being of the elderly may be associated with number of FNT and oral restoration behaviors.

Objective To explore the safety of the laparoscopic surgery in radical resection for different stage rectal cancer.Methods Clinical data of 200 cases with rectal cancer underwent laparoscopic radical resection(observation group) were analyzed retrospectively,including 52 cases of stage 0-Ⅰ,148 cases of stage Ⅱ-Ⅲ.Two hundred cases patients with rectal cancer underwent open radical surgery were selected as control group,including 44 cases of stage 0-Ⅰ,156 cases of stage Ⅱ-Ⅲ.The length to distal resection margin,the number of harvested lymph nodes,the incidence of postoperative complications and the prognosis of recent situation were observed,the safety of the laparoscopic surgery was analyzed.Results Whether rectal cancer of stage 0-Ⅰ or Ⅱ-Ⅲ,there were no significant differences in terms of the length of distal resection margin((2.5±0.9) cmvs.(2.4±1.1) cm,t=0.490,P=0.625;(3.1±1.0) cm vs.(3.2±1.3) cm,t=0.749,P=0.454),the number of harvested lymph nodes((12.3±4.2) vs.(12.7±3.9),t=0.480,P=0.632;(13.9±5.4) vs.(15.1±4.9),t=2.369,P=0.118),the incidence of postoperative complications (17.3％ vs.18.2％,x2 =0.012,P=0.911;27.7％ vs.28.8％,x2=0.049,P=0.825),the rate of local recurrence(1.9％vs.2.3％,x2 =0.014,P =1.000;4.1％ vs.3.2％,x2=0.157,P=0.692),the distant metastasis (3.8％ vs.2.3％,x2=0.195,P=1.000;5.4％ vs.4.5％,x2=0.137,P=0.712) and 3-year survival rate (96.2％vs.95.5％,x2=0.010,P=0.808;83.8％ vs.85.3％,x2=0.132,P=0.714) between the observation group and control group (P＞0.05).Conclusion For rectal cancer of stage 0-Ⅰ,laparoscopic surgery has good safety,and worthy of popularization and application.For rectal cancer of stage Ⅱ-Ⅲ,due to its operation for a long time as well as the possible risk in postoperative anastomotic fistula,the implementation of laparoscopic surgery should be more cautious.

OBJECTIVE: To observe the clinical and pathological features of adenoid cystic carcinoma(ACC) of external auditory canal (EAC, and analyze the possible factors related to prognosis. METHOD: One out of 8 patients with ACC of EAC underwent tumor open biopsy. 5 patients underwent the extensive tumor resection, and 2 patients underwent the modified lateral temporal bone resection (1 of the 2 subjoined a total parotidectomy). Five patients received the postoperative radiotherapy. RESULT: The time of follow up was 5-97 months. Two patients were loss to follow-up, 5 patients with disease free survival, and 1 patient survival with tumor. CONCLUSION In this study, ACC of EAC is more often observed in female. The most common clinical manifestations are otalgia and neoplasm which grows slowly. The disease has high misdiagnosis rate. Surgical treatment is effective for it.

ObjectiveTo evaluate the efficacy and safety of electrical acupuncture therapy through adhesive surface electrodes and concomitant auricular acupuncture therapy on acute spinal cord injury.MethodsA total of 56 acute spinal cord injury patients with American Spinal Injury Association(ASIA) impairment grading of A and B were recruited into this study.They were randomly divided into the acupuncture and control groups.In the acupuncture group,electrical acupuncture therapy via the adhesive surface electrodes and auricular acupuncture were applied.Rehabilitation therapy was also provided to the patients during acupuncture therapy.In the control group,only rehabilitation therapy was provided to the patients.The ASIA neurologic and functional scores and the Functional Independence Measure(FIM) scores were assessed during the time of admission,hospital discharge,and 1-year postinjury follow-up.There were no adverse events.ResultsThere were significant improvements in neurologic(sensory and motor),functional,and FIM scores in the acupuncture group compared with the control either when hospital discharged or 1-year postinjury follow-up.There was no adverse events.ConclusionThe early use of concomitant auricular and electrical acupuncture therapies are effective and safe in treating acute spinal cord injury.

ObjectiveTo describe 64 cases of cerebrovascular accidents temporally associated with cervical vertebra manipulation therapy in terms of patients' characteristics, potential risk factors, nature of complication, and neurologic sequelae.MethodsThree researchers using a uniform data abstraction instrument performed an independent review of 64 previously medicine records describing cerebrovascular ischemia after cervical vertebra manipulation. Descriptive statistics were calculated for characteristics of the patients and the complications. Means and standard deviations were computed for continuous variables. Frequencies were computed for continuous variables. Frequencies and proportions were calculated for categorical variables.ResultsProposed risk factors include age, gender, migraine headaches, hypertension, diabetes, birth control pills, cervical spondylosis, and smoking. It was unable to identify factors from the clinical history and physical examination of the patient that would assist a physician attempting to isolate the patient at risk of cerebral ischemia after cervical manipulation.ConclusionsCerebrovascular accident after manipulation appear to be unpredictable and should be considered an inherent, idiosyncratic, and rare complication of this treatment approach.

BACKGROUND: It is the most effective and economical method to reduce the incidence of stroke by conducting the health education concerning the etiological factors or risk factors and therapeutic knowledge of hypertension, diabetes mellitus and hyperlipidemia among the public and improving their knowledge level about the prevention and treatment of stroke.OBJECTIVE: To investigate the cognition of the knowledge concerning the prevention and treatment of stroke among the public in Dongguan area.DESIGN: A cluster sampling and simple randomized sampling survey.SETTINGS: Department of Neurology, the Fifth Affiliated Hospital of Sun Yat-sen University and the Department of Neurology, Affiliated Tungwah Hospital of Sun Yat-sen University.PARTICIPANTS: Between March and June in 2001, totally 2 500 cases were randomly selected by means of cluster sampling combined with simple randomized sampling from the residents and migrant populations no younger than 17 years old in the government organization, enterprises, factories of various forms, Dongguan University of Technology and senior middle schools of urban and rural Dongguan city and the administrative villages of the rural areas of Dongguan city in Guangdong province before March 2003.METHODS: The inventory was modified according to relevant literatures,including demographic data, general knowledge of stroke, and knowledge about the prevention, identification and treatment of stroke, and the pathway to obtain knowledge about the prevention and treatment of stroke.Each item for the knowledge about the prevention and treatment of stroke was marked as 1-4.5 points, and the total score was 60. There was no mark for the pathway to obtain knowledge about the prevention and treatment of stroke. One unit was investigated each time, and 300-600 questionnaires were sent out, 500 questionnaires were randomly handed out to the healthy physical examinees in the Tungwah Hospital.MAIN OUTCOME MEASURES: The correct rate of answers to the questionnaire, the total score of each kind of knowledge about the prevention and treatment of stroke, the total score of each kind of knowledge in the subgroups, and the pathways to obtain knowledge about the prevention and treatment of stroke were mainly observed.RESULTS: Totally 2 320 complete and effective questionnaires were collected back. ① The average correct rate of answers to all the questions was 49.80%, and those of knowledges about identification and treatment were lower, the total score was ＜ 60% in 48.20% of the subjects. ② The level for each knowledge about the prevention and treatment of stroke was lower in males than in females (P ＜ 0.05), but higher in the middle-age and old groups than in the young group (P＜0.05), and it was decreased from various civil servants, free agents, workers, farmers and students in order (P＜0.05), and there was significant difference between students and free agents (P＜0.01); it was also decreased in order from higher educational level to middle and lower ones in order (P＜0.05); it was also higher in the subjects with stroke history than in those without (P ＜ 0.05). ③) After the subjects were subdivided according to gender, age, profession and educational level, the pathways to obtain knowledge about the prevention and treatment of stroke in order were reading newspapers and magazines,watching TV, reading handbooks about science popularization, influence from relatives and friends, promotion and education of medical staff, and the last one was the least in all the groups.CONCLUSION: The level for the knowledge about the prevention and treatment of stroke was lower among the public in Dongguan area during the investigation, especially the knowledges about identification and treatment, so proper measures should be adopted to further develop education on the knowledge about the prevention and treatment of stroke.
