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 literature distribution and research status of depression in the elderly published in Chinese Medical Association journals.Methods The literatures of elderly depression published in 85 kinds of Chinese Medical Association journals from 2003 to 2012 were collected.The publication year,distribution,content,author,institution and region of these literatures were analyzed.Results From 2003 to 2012,there were 85 articles on depression in the elderly published in 15 kinds of journals of the Chinese Medical Association.These literatures were published mostly in 2011 (18 articles,21.2％),secondly in 2010 (13 articles,15.3％) and 2012 (12 articles,14.1％),which were published mostly in Chinese Journal of Geriatrics (29,34.1％).These articles mainly included basic science,inventory survey,diagnostic methods and clinical treatment strategy,and the most published form was treatise (77 articles,90.6％).The author who published the most articles was YUAN Gui yong from Nanjing (3 articles,3.5％),the institution which published the most articles was People's Hospital of Hainan Province (4 articles,4.7％),and the provinces or cities which published the most articles were Beijing (15 articles,17.6％),Shandong (9 articles,10.6％) and Zhejiang (7 articles,8.2％) by turns.Among the 85 articles,31 articles (36.5％) were supported by foundations.The definition,epidemiology,mechanism,influence factors,clinical characteristics,diagnosis and treatment strategy of elderly depression,and especially secondary depression were well discussed in these literatures.Conclusions The literatures of elderly depression published in Chinese Medical Association journals are insufficient in quantity,and more than half of the literatures are published from 2010 to 2012.The distribution of journals is relatively concentrated,but the distribution of author,institution and region in these articles is dispersed.Secondary depression in the elderly is concerned especially.

Objective To investigate the situation and development of international literatures on geriatrics and gerontology in mainland China.Methods The literatures on geriatrics and gerontology written by mainland Chinese scholars as the first author were selected from Thomson Scientific database in 1979-2011 period.Researches on basic theory,summary reports of clinical practice and reviews were collected.The quantity of published articles,article types,international cooperation research and funding programs,hospital rankings,as well as the 2011 geriatrics professional journals,thesis topic disciplines distribution and high-performance papers were analyzed by Thomson Data Analyzer software.Results From 1979 to 2011,the quantity of literatures written by Chinese scholars as the first author (not including Hong Kong,Macao and Taiwan regions) was 1927,including 1769 research articles,86 reviews,18 editorials,54 letters.Average paper was cited 7.6 times and the average number of article citation was 30.6.International cooperation research articles occupied 379 (19.7 ％).Articles with research sponsorship were 734 (38.1 ％),in which most subject discipline was geriatric and gerontology.Conclusions The development of geriatric medicine in China is rapid.The international scientific and technological cooperation is very extensive.It is important to further improve the world impact of geriatric medicine from China.The development of geriatric medicine in a large,cooperative,comprehensive,interdisciplinary,interagency direction,and the prospective,multicenter,cooperative study need to promote.It is extremely urgent to establish the English version of Chinese journals of geriatrics with a international influence.

Objective To explore the distribution and research status of literatures on Alzheimer disease (AD) published recently,to compare the differences in the research papers on AD between China and foreign countries,and to provide bibliometrics data for Alzheimer disease research.Methods Using bibliometrics methods,the characteristics and contents of Alzheimer disease research documents were analyzed in Pubmed database and Wanfang web by analysis tools.Research status of Alzheimer disease including the type of literatures and journal distribution from 2008 to 2012 was analyzed.Currently hot topics or top high frequency words were emphatically analyzed.Results There were 646 matched literatures for Alzheimer disease retrieved in Chinese core periodicals,and 19 423 literatures in Pubmed database.The articles for clinical study of Alzheimer disease were more than experimental and epidemiologic study among the 646 literatures.The disciplines distribution of AD in Chinese core journals was similar to international journals,mainly including nerves,brain,and geriatrics journals.The domestic research papers on Alzheimer disease were less than 5％ in Pubmed database,and the articles from Chinese journals in Chinese or English edition accounted for only a small proportion of Pubmed database.The recent research direction of Alzheimer disease in China was similar to foreign countries such as amyloid proteins,diagnosis and gene,but foreign research paid more attention to the metabolism,image and the aging mechanism in AD,while in China there were quite a lot of reports in the literatures on cholinergic drugs,tau protein,hippocampus and Chinese herbal treatments.Conclusions The AD-related disciplines distribution in China and foreign country is relatively fixed in recent 5 years.The AD researches carried out in China are close to those in foreign country,but researches on some areas still lag behind.The experimental and epidemiologic study on AD should be strengthen in China.

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.
