Objective To explore the clinical characteristics and diagnosis of primary small intestinal tumor(PSIT). Methods Retrospective analysis of the clinical and pathological data of the 31 PSIT cases was made. Results Duodenum was the most common site 67.74% for PSIT. The confirmed diagnosis rate was 54.84%(17/31)(duodenum was 66.67%,14/21; ileum and jejunum was 30%, 3/10, respectively ). 3 cases were benign tumors and 28 were malignant tumors.The adenocarcinoma was the most frequently seen malignant PSIT followed by lymphoma and often in duodenal. The features of the small intestinal tumor could be abdominal pain,abdominal mass,hemorrhage,obstruction,jaundice and fever.The chief method for diagnose was barium meal X-ray examination, especially with the hypotonic contrast X-ray examination and endoscopy.Superior mesenteric arteriography sometimes helped in determing site of gastrointestinal haemorrhage. CT scan could be helpful in diagnosis. Conclusion Duodenal adenocarcinoma is most common PSIT,followed by malignant lymphoma.Endoscopy is the best way to find out the tumor located in duodenum and hypotonic contrast X-ray examination is effective in diagnosis and locating of small bowl tumors.Superior mesenteric arteriography is a good way to find out angioma and leiomyoma. CT scanning are also helpful.

Objective To explore the relationship among family functioning,coping style,and psychopathic personality for adult male prisoners.Methods 328 adult male prisoners were surveyed with Family APGAR Index,Simplified Coping Style Questionnaire and Psychopathic Deviate Scale.Different demographic variables were compared on male prisoners'family functioning,coping style and psychopathic personality.Coping style and psychopathic personality were compared among family functioning groups,then a relationship model was set up by structural equation modeling.Results The low age male prisoners showed significant lower growth (1.17 ±0.76),resolve (1.11 ±0.79),negative coping style(1.15 ± 0.51),the total scale of family APGAR (5.61 ± 2.73) and higher psychopathic personality (22.11 ± 4.95) than the high age male prisoners ((1.35 ± 0.72),(1.45 ± 0.68),(1.30±0.58),(6.29 ±2.63),(19.40 ±5.06),t=2.17,4.15,2.51,2.31,4.89).The rural male prisoners showed significant lower adaptation (1.04 ± 0.69) and higher positive coping style (1.95 ± 0.40) than the city male prisoners ((1.21 ± 0.74),(1.81 ± 0.43),t =2.07,3.09).The positive coping style (P =0.024)and psychopathic personality (P =0.000) of adult male prisoners among family functioning groups showed significantly difference.The strongest positive effect that adult male prisoners' positive coping style forecast family functioning was 0.275.The strongest negtive effect that male prisoners' psychopathic personality forecast family functioning was 0.257.The strongest negtive effect that male prisoners' negative coping style forecast psychopathic personality was 0.197.The strongest positive effect that male prisoners' family functioning forecast psychopathic personality was 0.266.Conclusions Positive coping style and good family functioning could effectively adjust adult male prisoners' personality.Positive coping style and perfect personality could effectively improve adult male prisoners' family functioning.Family functioning and psychopathic personality interact with each other.

Objective To explore the relationship among family functioning,positive and negative affect in male prisoners, in which the mediating effect of neuroticism and self-acceptance.Methods 315 male prisoners were surveyed with Family APGAR Index, Positive and Negative Affect Scale, Neurotism Scale,and the Self Acceptance Questionnaire.To compare positive and negative affect,neuroticism and self-acceptance of male prisoners in different family functioning groups.In addition,structural equation modeling was established among above mentioned variables.Results (1) Male prisoners in the worst family functio-ning group showed significant difference(P<0.05) in positive affect (26.31±6.55),neuroticism (14.23± 5.11) and self-acceptance (40.58±4.31) with those in the good family functioning group ((29.88±6.48), (11.49±4.89),(42.77±4.97)) and those in the worse family functioning group ((29.80±4.49),(12.91± 4.58),(42.39±5.54)).(2) Male prisoners'family functioning was significantly related to positive affect ( r=0.28) ,neuroticism ( r=-0.30) and self-acceptance ( r=0.20) (P<0.01) .Negative affect was significantly related to neuroticism ( r=-0.25) and self-acceptance ( r=0.39) (P<0.01) .( 3) Neuroticism and self-ac-ceptance played a chain mediating effect between family functioning and positive affect (P<0.01) .Neuroti-cism also played mediating effects between family functioning and negative affect as well as between family functioning and self-acceptance (P<0.01) .Conclusion Family functioning,neuroticism and self-acceptance have significant predictive power for male prisoners'positive and negative affect.To improve family functio-ning of male prisoners is conductive to personality formation and self-acceptance,furthermore,expressing pos-itive emotion experience.

Objective To assess the value of color Doppler flow imaging (CDFI) in indicating the recurrence and prognosis of liver cancer.Methods Two hundred and eighty-seven patients with primary liver cancer were enrolled,thirty-seven cases received operations ( 12.9% ).The size,profile,margin,echogen,blood supply of the tumors were observed preoperatively by CDFI. Twenty-eight patients were followed for 0.5 to 5 years.Results Recurrent nodules were seen in 24 cases (85.7%) during five years.Lesions larger than 5 cm recurred much earlier than those less than 5 cm in the diameter of the patients( P

Objective To explore the influence of application of health management strategy on quality of life in outpatients with functional dyspepsia (FD). Methods A total of 140 FD patients were divided into the intervention group and the control group by random digits table method with 70 cases in each. The patients in the intervention group received the researchers on the implementation of health management strategy, and the patients in the control group were given routine outpatient health education and telephone follow- up. Before and after the intervention in one month or three, the FD patients Quality of Life Scale (FDDQL) was used to evaluate the quality condition of the patient's life. Results Eventually 65 cases in the intervention group and 61 cases in the control group completed the research. 1 months after intervention in the intervention group, total score of life quality and score of each dimension rose faster, in addition to the dimension of pressure, total score and daily activities, anxiety, diet, sleep, feeling unwell, health, disease control dimension scores were 73.84 ± 3.45, 81.22±4.55, 71.58±6.19, 73.05±5.14, 74.74± 5.58, 74.72±3.91, 79.26±5.85, 73.75±6.32, higher than 60.59 ±5.06, 76.04±6.06, 68.41±9.78, 69.52±6.68,66.63±9.87, 64.37±6.24, 54.50±7.96, 50.76±7.54, the difference was statistically significant (t =2.160-20.590, P < 0.01 or < 0.05). Three months after intervention, the intervention group the total score of life quality and score of daily activities, anxiety, diet, sleep, feeling unwell, health, disease control, pressure dimension scores were 76.35±3.74, 85.21±5.34, 80.15±5.86, 73.21±4.99, 75.49±6.81, 75.46±3.80, 79.35± 6.39, 74.06±6.74, 70.86±7.00, significantly higher than 58.60±5.22, 72.02±6.53, 59.26±7.81, 60.90±6.36, 61.19±9.08, 62.24±6.02, 54.15±8.25, 50.13±7.67, 60.02±5.67 in the control group, the difference of two groups was statistically significant (t = 5.726-19.946, P < 0.01). Conclusions Using health management strategy intervention for FD outpatients will improve FD patient′s quality of life.

Objective To explore life experience in chronic obstructive pulmonary disease (COPD) patients with the habit of exercise for more than 5 years,to enhance the confidence of participating in the rehabilitation in other patients, to help the medical staff pay more attention to guide the patients with COPD to take up the rehabilitation exercise. Methods The narrative research method in qualitative research was used to analyze the collected data. Results The study found that the coping approach of the contradiction between exercise and dyspnea, the ability to live together with the disease peacefully and the enthusiasm of persuing life were deserved to be learned. Conclusions Full of perseverance and persisted rehabilitation exercise may alleviate the symptoms, reduce the number of acute exacerbation of COPD and improve the quality of life for COPD patients. Medical staff should encourage COPD patients to participate in the rehabilitation in the right time with appropriate methods.
