Objective The study was to explore the effect of the Wechat combined with discharge supervision on rehabilitation of empty-nesters with total knee arthroplasty (TKA).Methods 100 emptynesters who were treated with unilateral TKA from September 2013 to August 2014 were selected and randomly divided into the experimental group and the control group with 50 patients in each group.All patients received the same orthopaedic hospital routine therapy and nursing,hospital rehabilitation exercise,guidance,family visits and conventional outpatient care.Besides the above treatment,the experimental group received nursing instruction after discharge by professional nurses through Wechat platform,which included functional exercise guidance,psychological guidance and daily activities instructions.The hospital for special surgery(HSS) knee score and the modified Barthel Index (MBI) score were assessed on the 14th day,the third month and the sixth month after surgery.Results HSS knee score and MBI score had no statistically significant difference between the experimental group and the control group on the 14 th day after surgery; HSS knee score and MBI score of the experimental group on the third month and the sixth month after surgery were significantly higher than those of the con-trol grou,t value was 9.24,11.07 and 21.92,14.14.Conclusions Wechat combined with discharge super-vision can effectively improve the rehabilitation effect of empty-nesters after total knee arthroplasty.

Objective To investigate the status of food intolerance of patients with ulcerative colitis,(UC),to provide the basis for directing UC patients diet related nursing.Methods Forty-seven UC patients were selected from September 2013 to August 2014 in General Hospital of Tianjin University.The Southerland Disease Activity Index (DAI) was used to divide the UC patients into remission,mild activity and moderate to severe activity groups.The food-specific IgG antibodies status were tested by enzyme-linked immunosorbent assay in UC patients and healthy people.Relevant clinical parameters were analyzed statistically.Results Food intolerance rate in UC patients was as high as 68.08％(32/47);the food species:egg,wheat and milk ranked the most frequently intolerance food.The food intolerance rates in remission,mild activity and moderate to severe activity groups were 9/16,11/18,12/13,there were significantly different,x2=7.418,P＜0.05.Extraintestinal manifestation group had significantly higher food intolerance rate compareed to non extraintestinal manifestation group:1 1/13 vs.55.88％(19/34),x2=2.234,P＜0.05.No significant difference of food intolerance rate were showed among groups categorized according to sex,age,body mass index,site of lesion,P＞0.05.Conclusions UC patients show higher food intolerance rate than healthy people.UC disease activity and extraintestinal manifestations are correlated to food intolerance,which is of great significance to guide diet related nursing of UC patient.
