A questionnaire survey was conducted among 319 mental health workers from 319 grassroots health institutions of 21 districts (cities,counties) in Chengdu in March 2013.The items of survey included general information of participants,subjective perceptions and status of community mental health services.Total 252 effective questionnaires were received,the average age of participants was (33.12 ± 9.39) years (19-61);59.5％ had clinical medicine and 16.3％ had public health background;most of them had educational levels of three-year college or below (84.9％);the average duration of working experience was 18 months;86.5％ was part-time;most of participants (87.4％) thought that the mental health service was a hard job and only 25.3％ expressed satisfaction with the work.Only 16.3％ of community health service centers had rehabilitation facilities for mental illness patients.Public health education was carried out for average (2.21 ± 1.62) times/year,the education for mental patients and family members was (1.62 ± 1.83) times/year.Between areas with sufficient detection rate of mental illness and those with insufficient detection rate,there was significant difference in training frequency of mental workers (P =0.012),there were no significant differences in having formal employment of mental workers (P =0.064),professional guidance,co-working with police officers,co-working with Disabled Persons' Federation,and the duration of working experience (all P ＞ 0.05).The results suggest that the capacity of mental health service in community levels is relatively weak in Chengdu,and the personnel training,public education and rehabilitation work of mental health need to be strengthened.

Objective To evaluate the effects of Prinsepia utilis Royle oil (PURO) on the synthesis of ceramide and expression of acid ceramidase N-acylsphingosine amidohydrolase 1 (ASH1),and to explore the mechanisms underlying its moisturizing and skin barrier-repairing effects.Methods Keratinocytes from human foreskin tissue were classified into 2 groups to be cultured in keratinocyte-serum free medium (K-SFM) with or without the presence of PURO.Enzyme linked immunosorbent assay (ELISA) was performed to measure the level of ceramide in the culture supernatant of keratinocytes at 0,3,8,24 and 48 hours.The back of nude mice was divided into 4 areas,i.e.,test area,matrix area,blank control area and negative control area.Acetone and ether were used to destroy the epidermal barrier in the test,matrix,and blank control areas,then,the former 2 areas were topically treated with emulsions containing 1％ PURO and matrix,respectively,and the blank control area remained untreated.The epidermal barrier remained intact and untreated in the negative control area.Noninvasive methods were used to determine transepidermal water loss (TEWL),epidermal moisture content and skin lipid content in these areas on day 0,1,3,and 7.Skin tissue was obtained from these areas on day 0 and 7 followed by an immunohistochemical study for the quantification of ASH1 expression.Results The level of supernatant ceramide increased with time in the PURO-treated keratinocytes,which was significantly higher at 24 hours and 48 hours than at 0 hour (1.3817 ± 0.100 and 1.3737 ± 0.047 vs.0.7630 ± 0.143,both P ＜ 0.05).The supernatant ceramide was also elevated in the PURO-treated keratinocytes compared with untreated keratinocytes at 24 and 48 hours (both P ＜ 0.05).Noninvasive skin tests showed a gradual decrease in the TEWL,but an increase in the epidermal moisture content and skin lipid content with time in the 3 epidermal barrier-destroyed areas.As far as the test area was concerned,TEWL value was significantly lower on day 3 and 7 than on day 0 (10.85 ± 0.64 and 8.01 ± 0.58 vs.12.65 ± 0.71,both P ＜ 0.05),while a significant increment was observed in the skin lipid content on day 3 and 7 compared with day 0 (29.14 ± 0.40 and 31.30 ± 0.88 vs.27.02 ± 0.65,both P ＜ 0.05),as well as in the epidermal moisture content on day 1,3 and 7 compared with day 0 (13.98 ± 0.28,15.00 ± 0.38 and 15.86 ± 0.18 vs.11.74 ± 0.62,all P＜ 0.05).On day 7,there was a statistical decline in TEWL value,but an elevation in epidermal moisture content,skin lipid content and ASH1 expression in the test area compared with the matrix area and blank control area (all P ＜ 0.05).Also,the expression of ASH1 was upregulated on day 7 compared with day 0 in the 3 barrier-destroyed areas (all P ＜ 0.05).Conclusion PURO may exert skin-moisturizing and barrier-repairing effects by enhancing the synthesis of ceramide and expression of acid ceramidase ASH1.

ObjectiveTo seek experimental evidence of epidermal barrier dysfunction in psoriasis,and to provide a basis for adjuvant therapy of psoriasis.MethodsPhysiometric methods were used to determine the value of sebum content,transepidermal water loss(TEWL) and water content of stratum corneum in 60 patients with psoriasis and 48 normal human controls.The ultrastructure of lamellar bodies was observed with transmission electron microscopy,and the expression of acid ceramidase in normal skin and psoriatic lesions was detected by using immunohistochemical techniques.ResultsCompared with the normal skin,TEWL value was increased(P ＜ 0.01),but water content of stratum corneum decreased(P ＜ 0.01 ) in psoriatic lesions,and sebum content was similar between normal skin and psoriatic lesions.As electron microscopy showed,lamellar bodies in keratinocytes were reduced in number with a disorganized arrangement and irregular size in psoriatic lesions.The expression of acid ceramidase also decreased in psoriatic epidermis.Conclusions The function of epidermal barrier in psoriasis is impaired,and to restore epidermal barrier function and enhance hydration may serve as an important adjuvant therapy of psoriasis.

Objective To evalutate the safty of hBMSCs transpalntation and to observe their migration and distribution in the brain of young macaca fascicularis. To establish a new technology platform and theoretical basis for the treatment of central nervous system diseases in children. Methods Labelled hBMSCs were transplanted into the striatum of young macaca fascicularis. Brain sections were examined to evalutate the inflammatory reaction and immunological rejection of local injection sites by HE observation and immunohistochemical staining. Migration and distribution of transplanted?hBMSCs was observed by real?time fluorescence quantitative PCR of male DNA and fluorescence microscope. Results The results showed that the direct intracerebral injection of hBMSCs did not cause systemic symptoms in animals. There is no inflammatory reaction and immunological rejection was detected, and degeneration and necrosis of neural cells and proliferation of glial cells were absent in the local injection sites. The transplanted hBMSCs survived, and migrated into the brain after 4 weeks transplantation. Its migration and distribution have certain regularity and were overlapping between transplant recipients. In addtion, hBMSCs tended to extend rostrally into the forebrain and showed preference of migrating toward the blood vessels and below the ependyma. Conculsions Intracerebral transplantation of hBMSCs is safe. And hBMSCs can survive and migrate into the brain.
