Parents and family background cast important influence on children's attachment style. Studies have consistently showed positive relations between maternal sensitivity and infant attachment security. Warm and harmonious family was also found to be an important factor. On the contrary, parents' poor marital status and high level of stress in family would result in insecure attachment style in children.

Magnetic resonance imaging (MRI),a commonly used imaging technique,has been extensively investigated in lung cancer diagnosis and staging.Many studies have demonstrated that MRI can be used for the differential diagnosis of benign and malignant pulmonary nodules and for the screening of lung cancer; it also has important value in TNM staging of non-small cell lung cancer (NSCLC),with equivalent sensitivity and specificity to 18F-fluorodeoxyglucose (18F-FDG) PET-CT,which suggests that MRI can be used as an alternative imaging modality in noninvasive diagnosis and staging of NSCLC.

The knowledge atlas for researches of invisible knowledge management was plotted after the key words and their relationship in papers on invisible knowledge published in the past 5 years were quantitatively and qualitatively analyzed by social network analysis, co-words cluster analysis, and impact factor analysis with the journal articles covered in CNKI, Wanfang, VIP Chinese Scientific and Technological Journals Databases as the data source.The hotspots and structure in researches of invisible knowledge management were then studied in order to provide reference for the innovative development and future research of invisible knowledge management.

Objective To observe the clinical effect of treating chronic renal failure with herbal retention-enema.Methods 23 cases with chronic renal failure were randomly recruited into a control group and a treatment group. The control group was treated with routine western medicine (low salt, low fat, and low protein diet, and correcting disturbance of water-electrolyte and acid-base balance), and the treatment group was treated with herbal retention-enema (Rhubarb, Concha ostreae, Dandelion, and Processing aconite). The clinical effect was observed in both groups. Results The clinical effect in the treatment group was significantly higher than that of the control group (χ2=3.456, P＜0.05). Conclusion The treatment of chronic renal failure with herb retention-enema is better than routine western medicine.

COX-2 and tumor are closely related.Pre-clinical studies have shown that the selective COX-2 inhibitor can strengthen the tumor radiation sensitivity function and chemotherapy medicine anti-tumor activeness,selective COX-2 inhibitor may provide new method and way for tumor prevention and treatment.

Objective To investigate the application of continuous renal replacement therapy in critically ill patients and clinical nursing measures.Methods 100 critically ill patients receiving continuous renal replacement therapy were chosen from October 2009 to June 2011 in our hospital and were given nursing intervention.The biochemical indicators before and after treatment were compared and analyzed.Results The biochemical indicators in patients improved significantly after continuous renal replacement therapy.There was significant difference.Conclusions Effective and comprehensive nursing for critically ill patients in continuous renal replacement therapy can improve the patients vital signs,improve the survival rate of them,and it should be carried out in clinic.

ObjectiveTo explore the current occurrence of upper gastrointestinal bleeding in elderly patients in our hospital and its possible risk factors and treatment program.MethodsAn observational prospective analysis of medical records of 758 consecutive patients was performed.Clinical presentation,etiology and treatment were evaluated.The follow-up ended on the dates of a first occurrence of UGIB,stopping co-therapy,death or 6 months after admitted in the group.Results426 male and 332 female were admitted in the group,UGIB occurred in 48 patients.PPI,H2RA,gastric mucosa protectant plus PPI,gastric mucosa protectant plus H2RA and control were prescribed in 108,240,70,102,238 patients respectively.There were statistics difference in each group compared with control in bleeding rate.ConclusionThe occurrence of UGIB associated with A + C co-therapy in elderly was 6.3％.Co-prescription with PPI and gastric mucosa protectant was associated with a lower risk.

Objective To study the influence of stay-at-home college students' resilience,self-supporting personality on psychological health state.Methods A sampling survey include 536 college students was done by psychological resilience list,self-supporting personality list,90 samptoms list (SCL-90),225 stay-at-home college students were taken as study group,and 311 non-stay-at-home college students as control group.Then the results were calculated and analyzed by SPSS13.0,and the calculating methods were listed as follows:analysis of variance,chi-square test,correlation analysis,linear regression and so on.Results ① The scores of family supporting,interpersonal independence of stay-at-home college students were apparently lower than those of non-stay-at-homes(F =5.826,P ＜ 0.05 ; F =6.614,P ＜ 0.05 ; F =4.163,P ＜ 0.05 ),but the score of independence was apparently higher than those of non-stay-at-homes(F =3.980,P ＜ 0.05).②The SCL-90 total scores and each factor score of stay-at-home college were narrow higher than those of non-stay-at-home college students,while the difference level still didnt reach significant level( all P＞ 0.05 ).The relevance ratio of apparent psychological symptoms of the two group college students didnt has significent calculating difference( all P ＞ 0.05 ).③ The SCL-90 total score item and most individual factor item of stay-at-home college students had apparent negative correlation with the interpersonal independence factor of their resilience and self-supporting personality (r =- 0.537 ～ - 0.132,P ＜ 0.05 ),while not apparent negative correlation with the individual independence factor(r =-0.118 ～0.105,P ＞ 0.05 ),and also they had very few correlation with the SCL-90 factor item which was relevant with interpersonal flexibility.④Emotion control,psychological resilience and interpersonal independence apparently negatively predict the physical and mental symptoms of those stay-at-home college students,with the predicting rate of 33.7％.Conclusion Stay-at-home experience has effects on the family-supporting,bearing power,independence and interpersonal independence of college students ;Emotion control,psychological resilience and interpersonal self-supporting are the protecting factors of the psychological health condition of college students.

Digestive tract reconstruction is one of the important steps following pancreatoduodenectomy.Traditional methods of digestive tract reconstruction,such as Whipple,Child and Cattel method,had disadvantages of bringing damage to the normal physiological structure and raising the incidence of complications.In this review,the improvements of the digestive tract reconstruction in recent years were introduced,and their benefits and shortcomings were also analyzed.

There is a common consensus amongst pathologists as to how to determine and examine the pancreatic,biliary tract and gastrointestinal surgical margins for specimens after pancreaticoduodenectomy (PD).However,for the retroperitoneal surgical margin which is one of the most important surgical margins in PD has not been well studied,and its determination remains unclear.In the present study,the definition,evaluation criteria and clinical significance of retroperitoneal surgical margin in PD were analysed.The relationship between R0,R1 resection rates and survival rates were compared.We presented a new technique to obtain a negative surgical margin in the uncinate process of the pancreas.
