The planning area of the entire piggery was 5 700 m2 with workplace and green belts. The sow house was 93 m long and 33 m wide, a total of 3 069 m2, including office area of 60 m2 and aisle area of 107 m2. The fer-mentation bed had an area of 2 902 m2 with length of 88.7 m and width of 27.7 m. lts area accounted for 95% of the total area of sow house. The fermentation mattress had a depth of 80 cm, and had a volume of 2 321 m3, equivalent to 733 t of coconut chaff and rice chaff. On a large fermentation bed, the areas for boars, replacement gilts, pregnant sows, obstetric tables, nursery pigs, etc. were designed. The large-scale sow house with fermentation bed was equipped with the automatic feeding system, automatic sprinkler system, automatic positioning column for preg-nant sows, sows＇ obstetric table system, fanning wet curtain cooling system, video monitoring system, environmental monitoring （light, temperature, water, humidity, CO2, NH3） and automatic control system. Every farming area was equipped with feeding trough and water trough. The water though was fixed with overflow pipe for removing the extra water. The house could hold 500-head sows. Each sow occu-pied 4.9 m2 of the fermentation bed in average. The designed sow house had a maximum annual output of 10 000 piglets.展开更多

Methods The trial was a double-blind, placebo-controlled, parallel- group design. The eligible patients were randomized into 2 treatment groups： sarsasapogenin group （sarsasapogenin plus risperidone for 8 weeks, n = 41） and placebo group （risperidone only for 8 weeks, n = 39）. At the baseline, as well as at weeks 2, 4 and 8 of treatment, the therapeutic response was measured by using scales including Positive and Nega- tive Symptoms Scale （PANSS）, Wechsler Memory Scale （WMS）, modified Chinese Wechsler Adult Intelligence Scale （mWAIS）, Clinical Global Impression （CGI） and Brief Psychiatry Rating Scale （BPRS）. The study period for each subject was 8 weeks and duration of overall trial was 2 years. Results Patients treated with sarsasapogenin plus risperidone demonstrated no statistically significant differences in changes in PANSS, WMS or mWAIS score at the end-point of the trial compared with patients treated with placebo plus risperidone. The incidence of treatment-emergent adverse events in patients treated with sarsasapogenin was not different from that observed in placebo group. Conclusion Sarsasapogenin did not augment the efficacy of risperidone in treating negative symptoms dominated schizophrenia. Sarsasapogenin at a dosage of 200 mg per day added to a flexible dosage of risperidone at 2-4 mg per day is safe and well tolerated by patients with negative symptoms dominated schizophrenia.展开更多
