Objectives:To investigate the effects of total parenteral nutrition (TPN) and somatostatin in the treatment of acute pancreatits. Methods: Patients were divided into two groups. Group A was patients treated from 1990 to 1994 with traditional non operative methods. Group B was patients treated from 1995 to 2000 with traditional methods plus both TPN and somatostatin. Results: In group B, morbidity, mortality and hospital stay were improved when compared with group A. The serum albumin concentration was below the normal at the beginning and was not different between the two groups. After the treatment of 15 days,the serum albumin concentration of group B was increased significantly and it remained almost the same in group A. Conclusions: Somatostatin and TPN can significantly improve the treatment effects of acute pancreatitis.

Objective To explore the psychometric properties of the Chinese version of the Functional Ability of Visually Impaired Questionnaire (CfaVIQ) by using Rasch Analysis. Methods The faVIQ was translated and adapted into the Chinese-version faVIQ (CfaVIQ). The CfaVIQ was completed by 215 visionlly impaired patients. The data were Rasch-analyzed with the Rating Scale Model of Andrich for calculating item fit statistics, determining the separation index by using Winsteps Rasch measurement program. Results Rasch model analysis indicated individual separation index (3.55) and project separation index (8.01) were both arithmetic greater than 2; the inlier-sensitive fit Mean Square (infitMnSq) and outlier-sensitive fit Mean Square (outfitMnSq) of Items, Persons were both within the range of 0.5-1.5, indicating great coincidence to the model;Wright map analysis showed the distribution of the sample ability and item difficulty was ideally normal. Coefficient of internal consistency was 3.55, separation reliability was 0.93. Pearson correlation coefficient of test-retest reliability was 0.92. Pearson correlation coefficient between CfaVIQ and vision (-0.67), visual acuity (-0.14). The National Eye Institute 25 Item Visual Function Questionnarie (NEI-VFQ25) (0.79) indicated a good construct validity. All the items′outfitMnSq, except outfitMnSq>1.5 of item 10 and item 23,were within the range of 0.5-1.5. Criterion Validity was 0.922 (95%CI:0.858-0.987). Conclusions The CfaVIQ is a culturally specific vision quality of life measure instrument. It can sensitively assess the quality-of-life in the visually impaired group. Rasch measurement model can provide comprehensive and positive information and has good application prospects for analysis of CfaVIQ.

Objective To explore the risk factors of breast cancer recurrence for the cause exploration and prevention of the disease.Methods With matched case-control method,a survey was conducted among survival cases of histologically diagnosed breast cancer patients in Southern hospital from January 2004 to December 2007 in Guangzhou city.The survival cases were divided into case group and control group according to the inclusion criteria.Unconditional logistic model was used to analyze the data.Results Multiple factors logistic regression analysis showed mental stimulations [OR =10.926,95％CI (5.041-23.682)],oral contraceptive pills history [OR=2.634,95％CI(1.548-4.482)],benign breast disease history [OR=5.183,95％CI(2.100-12.790)],human epiderma growth factor receptor-2 (HER2) positive [OR=2.257,95％CI (1.326-3.843)],lymph node metastasis [OR=2.021,95％CI (1.272-3.212)],distant metastasis [OR=3.718,95％CI (2.125-6.503)] might be associated with the increasing breast cancer recurrence risk.Regular exercise [OR=0.460,95％CI(0.234-0.905)],low stage of disease [OR=0.106,95％CI(0.022-0.498)],breast nursing time [OR=0.053,95％CI(0.009-0.316)],dietary intake of soy isflavones[OR=0.154,95％CI (0.032-0.745)] might be associated with the decreasing breast cancer recurrence risk.Conclusions Clinical medical staff should take attention to the breast cancer who had benign breast disease history to ensure timely check-ups,early detection,early diagnosis and early treatment.Improving physical and psychological quality,reducing oral contraceptive pills,prolonging breast nursing time,and increasing dietary intake of soy isflavones were important to the prevention of breast cancer recurrence.

Objective To evaluate the clinical effects of magnetic attachments in complete overdenture. Methods Casting method was used to fabricate Coping-Keepers for remained roots, and the patients were followed up for 6 months to check the effects of the overdentures retained with Magfit EX attachments. In the experimental group, 21 complete overdentures were made with 33 Magfit EX magnetic attachments for 18 patients. Eleven patients treated with traditional complete overdentures were selected to act as control. The retention force, aspect and comfortableness were subjectively evaluated by the patients of the both groups. Abutment status was observed and compared before and after cementation of the magnetic attachments by measuring periodontal index, including gingival index (GI), sulcus bleeding index (SBI) and bleeding on probing (BOP), etc. Masticatory function of patients in the both groups was measured at 3 time points: immediate, 3 months and 6 months after cementation. Results Patients in experimental group were more satisfied with complete overdentures made up of magnetic attachments than those in control group, especially in retention force and masticatory efficiency and aspect. Magnetic attachments can provide enough retention force for patients and greatly improved the masticatory efficiency and the abutment condition. The masticatory function was to be perfect and stable after 3-6 months. Furthermore, the mobility and periodontal index of most abutments improved after 6 months. Conclusion It is proved that magnetic attachments are effective to improve the function of complete overdentures, worthy to be used widely. It is suggested that the residual root and loosened tooth should be preserved furthest as possible in clinic.
