Medical imaging is evolving from the traditional morphologic examination to a pattern that combines morphologic and functional examinations that can reflect physiochemical changes at cellular and molecular levels. Functional imaging techniques, including CT perfusion imaging, MR diffusion weighted imaging, MR perfusion imaging and MR spectroscopy, have been drawing increasingly more attention in pathological study of the livers, pancreas, kidneys, prostates and lymph nodes, and the prospect is promising. CT & MR functional imaging combined with morphologic examination is helpful for the diagnosis and differential diagnosis of pathological lesions.

Objective To investigate the status of parenting stress in the primary care-givers of children diagnosed with autistic disorder and sum up the nursing strategies. Methods Seventy-eight primary care-givers of children diagnosed with autistic disorder were interviewed using the parenting stress index-short form (PSI-SF). Results The mean score of parenting stress was 104.08 ± 18.32, which was at a high level. The 3 subscales score from high to low:parenting anxiety(36.22 ± 8.46);disabled children (35.64 ± 6.41);parent-child interation disorder(32.01 ± 7.15). Conclusion Medical staff should pay more attertion to these care-givers in order to enhance their ability to cope with various problems in the parenting process and hence reduce the level of parenting pressure.

An analysis is made on major issues and difficulties in the application of the performance appraisal system structure,appraisal model and appraisal outcomes.It was discovered that the performance appraisal system,if used in clinical medical technology departments in the hospital,should focus on the system itself,the appraisal process and re-improvement of the system.These three factors are key to determining whether the system is effective and efficient,and key to transforming the system into departmental and hospital performance,even into overall enhancement of hospital performance in general.

Objective To observe the effect of motor relearning program (MRP) on balance function of stroke patients.Methods Sixty stroke patients were randomly divided into the MRP group and control group with 30 cases in each group. The patients of the control group were trained with proprioceptive neuromuscular facilitation (PNF) therapy; those of the MRP group were trained with the MRP therapy. The balance function of all patients was assessed with the Fugl-Meyer Balance Function Assessment before and after training.Results After training, the scores of Fugl-Meyer Assessment of all patients increased ( P<0.05), but scores of the patients of the MRP group were significantly higher than that of the control group ( P<0.05).Conclusion The MRP training can improve the recovery of balance function of stroke patients.

Objectives: To explore the epidemiological distribution of body mass index(BMI),waist to hip ratio(WHR) and abdominal circumference in population of Nanjing,Jiangsu Province. Methods: BMI, WHR and abdominal circumference were measured on 3 445 healthy cases aged 18～90 of Nanjing. Epidemiological distribution of BMI,WHR and abdominal circumference were analyzed according to sex and age. Results:The total mean BMI was( 23.28 ?3.49)kg/m 2, and the BMI in male was higher〔(23.80?3.36)kg/m 2〕 than that in female 〔(22.25? 3.49)kg/m 2〕( t =12.75, P

Objective To analyze the flow tendency of elderly patients,create a better mechanism to help guide elderly patients to form a good order in seeking medical care,and consequently improve the resource operational efficiency in medical service.Methods Analyzing the data by the descriptive,χ2 test and logistic regression of SPSS 20.0.Results Elderly patients prefer community health service centers and tertiary hospitals;of those visiting tertiary hospitals,nearly 30% seek medical advice for common chronic diseases.Main influencing factors for patient flow are medical insurance coverage and education. They tend not to embrace the two-way referral service,due to such factors of inconvenient process and defective mechanisms.Conclusion Transition from medical demand management to medical supply management.Such factors as quality cost,expense cost,time cost,and public opinion cost should be used to replace and weaken their mindset of the medical hierarchy,and embrace the concept of “seeking medical advice by grades”,thus improving the utilization of medical resources,and optimizing medical service accesibility.

Objective To investigate the correlation of blood lipid metabolism abnormity and other components of metabolic syndrome on angiocardiopathy and cerebrovascular diseases in the elderly people. Methods The clinical data of elderly people, who underwent medical examination during 1996 to 2005 in the General Hospital of PLA, were retrospectively analyzed. Based on the analysis, the co-existence of blood lipid disorders with glucose metabolic abnormity, hypertension and obesity, as well as their influence on cardio-cerebrovascular diseases were further analyzed. Results The prevalence of blood lipid metabolic disturbance was 69.6%, in which the prevalence of hyper-cholesteremia and hyper-triglyceride were 23.6% and 21.7%, respectively. The prevalence of hyper-cholesteremia accompanied by hyper-triglyceride (mixed group) was 19.3%, that of hyper-triglyceride with lower high density lipoprotein cholesterol was 5.03%, while it was 30.4% in the normal group. There was a higher risk of having the above abnormal condition in patients with type 2 diabetes mellitus (T2DM) and obesity, and they were more frequently complicated by hypertension in the hyper-triglyceride group (70.8%). When the patients with lipid metabolic disturbance were complicated by T2DM, hypertension and obesity, the prevalence of cardiovascular or cerebrovascular diseases increased. The prevalence of CHD was higher in the patients with hyper-cholesteremia and hypertension or diabetes, and incidence of both CHD and CVD was higher in the patients with hyper-triglyceride and either one of hypertension, diabetes or obesity. Conclusion There is high prevalence of lipid metabolic disturbance (more than two thirds) and other components of metabolic syndrome, and high risk of suffering from cardiovascular or cerebrovascular diseases in elderly people. The aging patients with hyper-triglyceride are vulnerable to cardiovascular or cerebrovascular diseases, and more attention should be paid in clinical practice in future.

Objective To analyze the significance of the waistline (WC), body mass index (BMI) and hyperinsulinaemia (HIns) on evaluating the metabolic syndrome. Methods The data of routine clinical examination were collected from the mid-aged and senile individuals (middle-senile group) who received oral glucose tolerance test (OGTT) for diabetes screening, and from a group of subjects who received annual OGTT for diabetes screening (mature group). Data were collected by a specialized person, input into a special computer database, and then analyzed with SAS 5.0 software by specialized staffs. Abnormal WC and BMI were determined according to IDF and CDS criteria. HIns was determined if fasting insulin (FIns) ≥15mU/L and 2-hour insulin after glucose burdening (2hPIns) ≥80mU/L. Results In the middle-senile group, the abnormality frequencies of WC and HIns as well as overall insulin level were obviously higher than that in the mature young group. The abnormality frequency of BMI was higher in mature young group. A higher detection rate of HIns existed in intolerance glucose test (IGT) and normal glucose test (NGT). The coincidence of WC and BMI diagnostic criteria were 77.5% and 74.3%, respectively, on evaluating with or without obesity in the middle-senile group and mature young group. When only WC criterion was used for evaluating the existence of insulin resistance, there would be 28.2% of missed diagnosis rate for MS patients. Conclusion WC, BMI and HIns are all risk factors for abnormal glucose metabolism, hypertension and dyslipidemia. There is different prevalence among different populations. The combination of WC, BMI and HIns might be more helpful for identifying MS at early stage.

Cantharellus Adans. ex Fr., a member of the Cantharellaceae, Cantharellales, Homobasidiomycetes, Basidiomycota, is a widely distributed macro-fungal genus with an independent evolutionary lineage. It currently includes 65 species, of which 9 were recorded in China. In this article, research history of the genus was briefly reviewed and some controversial conclusions, especially the demarcation and naming of some taxa, discrimination among similar species, problems on C. cibarius Fr. and C. tubaeformis Fr.: Fr. complex, as well as their ecological conservation and bionic cultivation, are discussed based on the authors’ findings. Proposals for further research on biodiversities and sustainable utilizations were put forward at last.
