By analyzing the scope and demands of mental health service in general hospitals, the authors point out that at present domestic general hospitals are confronted with such problems as insufficiency of resources for mental health service, low recognition rate of dysphrenia, and lack of systematic consultations and liaison in psychiatric work. Then they put forward a number of measures for improving mental health service in general hospitals: ①establishing a department of psychiatry in each general hospital; ②widely conducting consultations so as to maintain a strong liaisom in psychiatric work; ③genuinely achieving the transformation of the medical mode; ④strengthening education in psychological medicine and the spread of popular science so as to broaden the channel and coverage of mental health service and meet the needs of reform and development of the health cause in the contemporary era.

Objective To study the protective effects of th e polypeptides isolated from Chlamys farreri(PCF)against ultraviolet B radiatins.Methods An oxidative damage model of HeLa epi thelial cell line irradiated by ultraviolet B(UVB 7.15?10 -5 J /cm 2 )was established.The HeLa cells were randomly divided into six groups:control group,UVB radiated groups(radiated control,0.5%PCF,1%PCF,2%PCF,1%Vit C).The enzymic activities of HeLa cells were tested by MTT methods,the apoptosis rate an d death rate of HeLa epithelial cells and the content of free calcium in those cells were tested by using flow cytometry(FCM).The contents of MDA and the activities of GSH-Px ,SOD,CAT in the supernatants of cells were determin ed by biochemical methods.Results The results indicated that polypept ides fromChlamys farreri could enhance the activities of GSH-Px,SOD,CA T and decrease the contents of MDAin the su pernatants of HeLa cells,increase t he concentration of cellular free calciumin the cells,and decrease the rates of apoptosis and cell death of the cells .Conclusions The PCF has the protective effects on the HeLa cells irradiated by ultraviolet B.The mechanism of th is effects of PCF may be mediated by e-liminating the free radicals,by increasing the activities of antioxidative enzymes to inhibit the oxidativ e damages caused by UVB .

Objective To analyze the complications, treatments and prognosis of simultaneous pancreas-kidney transplantation. Methods Forty cases of simultaneous pancreas-kidney transplantation performed between Dec. 1999 and Jan. 2010 in our center were retrospectively analyzed. Results Regarding surgical complications, 4 cases had severe hematuria after operation,which needed clinical intervention, including 1 patient receiving catheterization in duodenum to stop bleeding. Two patients were treated with continuous bladder irrigation, and the remaining one received surgical haemostasis because of donor's duodenum and bladder anastomotic artery hemorrhage.Abdominal hemorrhage occurred in 4 patients, including pancreatic hemorrhage in 3 cases and duodenal muscularis hemorrhage in one case. All of them received surgical treatment for hemostasis.Abdominal infection occurred in 8 cases: one died of multiple organ failure, 2 cases were cured after drainage of abscess, 2 cases underwent surgical removal of abscess, and 3 cases were cured after antibiotic therapy. In one case of postoperative anastomotic leakage, pancreas was resected. Four cases of postoperative ileus were cured by continuous clysis with traditional Chinese medicine. Seven cases had pulmonary bacterial infections, including one cases associated with fungal infection. They were cured by the anti-infective treatment. Other complication included poor healing in 5 cases and urinary infection in 2 cases. After combined simultaneous pancreas-kidney transplantation, 10 patients received reoperation because of surgical complications (14 operations). The re-operation rate was 25 %, including 2 patients (4 operations) for hematuria, 4 patients for abdominal hemorrhage, 2 patients (3 operations) for abdominal infection, 1 patient for pancreatic venous thrombosis, 1 patient for anastomotic leakage, and 1 patient for pancreatic fistula. Conclusion Although simultaneous pancreas-kidney transplantation provides a successful and effective treatment for diabetics with endstage renal disease, surgical complication is still affecting the pancreas and kidney grafts after transplantation.

With the aging of the global population,frailty is now considered a unique old age syndrome,has become an important worldwide public health problems.The elderly people is at increased risk of falls,hip fractures,disability,death and other risks.Motor system disease as an independent risk factor participates in frailty progress and interacts with each other.This article reviews recent studies on frailty and motor system diseases.
