Objective To create the effective community-based day-care model of mental disability with multiple approaches. Methods 30 subjects with schizophrenia in Taoranting community in Beijing were selected in control group (n=15) and intervention group (n=15). A day-care multiple rehabilitation model had been implemented in the intervention group. They were evaluated with Positive and Negative Syndrome Scale (PANSS) and WHO Disability Assessment Schedule 2.0 (WHO-DAS 2.0). Results The scores of PANSS negative symp-tom, general psychopathological symptom and WHO-DAS 2.0 significantly reduced continually in the intervention group 8 and 12 weeks af-ter intervention (P<0.01). Conclusion Community-based day-care model can improve the rehabilitation of mental disabled people and inte-grate the community resources for the schizophrenics.

ObjectiveTo evaluate prognostic factors and the surgical results of pulmonary carcinoid tumors.Methods We retrospectively reviewed the medical records of 62 patients who were diagnosed as pulmonary carcinoid tumors between January 2000 and October 2010 at Department of Thoracic Surgery,Shanghai Chest Hospital.The following information was available for each of the 62 patients:age,sex,pathological type,and TNM stage.ResultsThere were no operative death.The 3-year and 5-year survival rates after surgery were 92.1％ and 77.8％,respectively.Of the 62 patients,42 were diagnosed as typical carcinoid tumor,and among them,4 patients (8.3％) had lymph node metastases.Their 3-year and 5-year survival rates were 97.8％ and 94.7％,respectively.The remaining 20 patients were diagnosed as atypical carcinoid tumor,and among them,6 patients (37.5％) had lymph node metastases.Their 3-year and 5-year survival rates were 84.4％ and 58.8％,which were statistically significant compared with typical carcinoid tumor( P =0.0047 ).There was significant difference in survival rate between the patients with lymph node metastases and the patients without lymph node metastases (P =0.0048).CondusionThe main risk factors affecting survival rate of those patients who were diagnosed as pulmonary carcinoid tumors were pathological types and lymph node metastases.

Objective To evaluate the role of prostaglandin E2 (EP) receptors in H9c2 cardiomyocyte hypertrophy induced by prostaglandin E2 (PGE2).Methods Primary cultured H9c2 cardiomyocytes were seeded in culture flasks (3 ml/flask) or in 24-well plate (1 ml/hole) or 6-well plate (2 ml/hole) with density of 4 × 104/ml.The cells were randomly divided into 4 groups (n=24 each): control group (group C),PGE2 group,AH6809 (EP1 and EP2 receptor antagonist) group (group A) and GW627368X (EP4 receptor antagonist) group (group G).The cells were continuously cultured for 48 h.PGE2 (final concentration 1 μmol/L) was added to the culture medium in PGE2 group.PGE2 (final concentration 1 μmol/L) and A H6809 (final concentration 10 μmol/L) were added to the culture medium in group A.PGE2 (final concentration 1 μmol/L) and GW627368X (final concentration 10 μmol/L) were added to the culture medium.The cells were then cultured for 48 h in groups PGE2,A and G.Then the cell morphology was observed by using fluorescent microscope.The cell diameter was measured by using the Image J medical image analysis system.Total protein content in the cells was measured with BCA method.The expression of atrial natriuretic peptide (ANP) mRNA and brain natriuretic peptide (BNP) mRNA in the cytoplasm was determined using RT-PCR.Results Compared with group C,the total protein in the cells and cell diameter were significantly increased,and the expression of ANP mRNA and BNP mRNA in the cytoplasm was up-regulated in groups PGE2,A and G (P ＜ 0.05).Compared with group PGE2,the total protein in the cells and cell diameter were significantly decreased,and the expression of ANP mRNA and BNP mRNA in the cytoplasm was downregulated in group G (P ＜ 0.05),and no significant change was found in the parameters mentioned above in group A (P ＞ 0.05).Conclusion EP4 receptor mediates H9c2 cardiomyocyte hypertrophy induced by PGE2 and the effect is not related to EP1 and EP2.

Objective To investigate the prevailing status of endemic fluorosis in the south area of Shandong province and to provide a scientific basis for formulating control measures against the disease.Methods According to the present distribution of fluorosis areas in the south area of Shandong province and the Shandong Province Technical Scheme for Endemic Disease Control,13 counties(districts) in the south area of Shandong province were selected as the survey counties in 2009.Based on the state of endemic fluorosis,the disease was classified into light,moderate and severe types in the 13 monitoring counties (districts),and one diseased village was selected from each type as the survey spots.The drinking water fluoride level,the prevalence of dental fluorosis of children aged 8-12,adult clinical skeletal fluorosis and urinary fluoride level of the children and adults were surveyed in the 39 villages selected.The content of fluoride in drinking water and urine was dctermined by F-ion selective electrode while dental fluorosis of the children aged 8-12 was diagnosed by Dean method and adults skeletal fluorosis by the national standard for Diagnosis of Endemic Skeletal Fluorosis (WS 192-2008).Results A total of 172 water samples were tested in the 39 villages(26 villages with improved water and 13 villages with unimproved water) of the 13 counties(districts),the fluoride content of the 74 water samples(51 from 13 villages with unimproved water and 23 from 6 villages with improved water) exceeded the national standard(＞ 1.0 mg/L),and the rate of exceeded the standard was 43.02％(74/172) with 24 of ＞ 2.0-4.0 mg/L and 3 of ＞ 4.0 mg/L,and the maximum value of the water fluoride was 7.76 mg/L.A total of 1118 copies of children urine samples were tested,geometric mean of urinary fluoride was 1.82 mg/L; 764 copies of adults' urine samples were tested,geometric mean of urinary fluoride was 1.98 mg/L.A total of 1908 children aged 8-12 were examined of dental fluorosis,the detection rate was 45.18％ (862/1908),tooth defection rate was 9.12％ (174/1908),and dental fluorosis index was 1.07.A total of 25 295 adults were checked of clinical skeletal fluorosis,the detection rate was 5.96％(1509/25 296) with 670 moderate or scrious cases.Conclusions In the south area of Shandong province,excessive water fluoride is still serious,mainly in the diseased villages with unimproved water(including water improvement villages discarded water improvement thereafter).Urine fluoride remains at a relatively high level,and the dental and skeletal fluorosis are still comparatively serious.High tluoride hazard still exists to a certain degree.Therefore,the scientific control measures need to be strengthened to control the prevalent of endemic fluorosis.

ObjectiveTo investigate the water fluoride level of the water improvement project and the prevalent condition of endemic fluorosis in 4 counties in Shandong province,and to provide a scientific basis for the development of control strategies to endemic fluorosis.MethodsAccording to “Shandong Province Survey Scheme of Endemic Fluorosis”,the service conditions of normal operated water improvement project and water fluoride content were investigated in Gaomi,Jiaxiang,Yuncheng and Boxing counties from May to November in 2010.The fluoride content in drinking water,the prevalence of dental fluorosis and urinary fluoride in children were investigated in nine major survey villages of the four counties.Water and urinary fluoride were determined by ion selective electrode and examination of dental fluorosis was done by using Dean method.ResultsA total of 288normal operated water improvement projects were examined in the 4 counties,the qualified rate of water fluoride (≤ 1.00 mg/L) of the projects was 51.39％(148/288),mean water fluoride was 1.35 mg/L and the maximum value was 6.27 mg/L.A total of 26 copies of drinking water samples were measured,the fluoride content ranged from 0.62mg/L to 4.36 mg/L,and mean water fluoride was 2.02 mg/L.A total of 685 children aged 8 to 12 were examined in the major investigated villages,the detection rate of dental fluorosis was 80.14％ (549/685),detectable rate of the defective dental fluorosis was 15.33％ (105/685),and dental fluorosis index was 1.56.Three hundred and seventynine copies of child urine samples were tested,the geometric mean of urinary fluoride were 0.66 - 13.28 mg/L,and the average was 3.04 mg/L.ConclusionsNearly 50％ of the water fluoride level of the water improvement project exceeds the standard ( ＞ 1.00 mg/L) in the 4 countries.The detection rate of dental fluorosis exceeds 80％ and urinary fluoride is significantly exceeds the standard in the major investigated villages.The endemic fluorosis is still serious and the situation of prevention and control of the disease is still grim.

Methods According to "The National Technical Scheme for Endemic Disease Control in 2007", 19 counties were chosen to carry out the epidemiological investigation in 2008. Water and urinary fluoride were determined by F-ion selective electrode, dental fluorosis of children aged 8 to 12 were diagnosed by Dean method and skeletal fluorosis of adults over the age of 16 were examined clinically and by X-rays. Results In 19 counties, 186 villages were surveyed, 44 villages were found with mean water fluoride ≤ 1.00 mg/L, accounting for 23.66%(44/186);the value ＞ 1.00 mg/L in 142 villages,accounting for 76.34% (142/186);maximum water fluoride 8.88 mg/L. Total detection rate of dental fluorosis of children aged 8 to 12 was 66.35% (4518/6809), dental fluorosis index was 1.55, and defect rate was 15.39%(1048/6809). Children with urinary fluoride ＞ 1.40 mg/L was 83.29%(2149/2580), and the maximum value was 31.92 mg/L. Detection rates of skeletal fluorosis clinically and by X ray among adults over 16 years were 6.37%(5577/87 607) and 20.23% (229/1132), respectively. Conclusions Endemic fluorosis in Shandong province is still serious, prevention efforts need to be further increased.

It is to observe the therapeutic action of Guizhi Fuling capsule and the combination of active ingredients on model rats with uterine leiomyoma. The hysteromyoma rats models was established in rats by loading eatrogen, to observe the effect on pathological condition of uterus, uterus wet weight, the content of estradiol and progesterone. Guizhi Fuling capsule and the combination of active ingredients remarkably decreased uterus weight, restrained the excess proliferation of the smooth muscle of uterus, decreased the estraiol and progesterone in blood serum. Guizhi Fuling capsule and the combination of active ingredients can restrain the formation of hysteromyoma in a dose-dependent manner. Perhaps the combination of active ingredients is the material foundation of antihysteromyoma.
