Objective:To analyze the management and treatment of patients with psychosis in china in 2020 and compare with those in the past five years to provide a reference for making policy and service delivery.Methods:Descriptive analysis was used to analyze the system usage and registration, management, and treatment situation of the patients with psychosis, using the data obtained from 'National Information System for Psychosis′ in China, with date traced from 1st August 2011 to 31st December 2020.Results:By the end of 2020, the information system was adopted by 100% of districts/counties. 6 430 587 patients were registered, with a registered rate of 0.46% (6 430 587/1 396 537 459). In 2020, 6 116 599 patients were provided with follow-up services by primary healthcare staff, with a management rate of 95.12% (6 116 599/6 430 587). 5 724 019 patients were followed up regularly, with the regular management rate of 89.01% (5 724 019/6 430 587). Moreover, the medication-taking rate was 87.83% (5 648 162/6 430 587), and the regular medication- taking rate was 68.84% (4 426 498/6 430 587). 5 277 746 patients were stable, and the stable condition rate was 96.40% (5 277 746/5 474 881). Compared with 2019, 200 430 more patients were registered in 2020. The management rate, regular management rate, medication-taking rate, regular medication-taking rate, and stable condition rate were increased by 0.88%, 2.50%, 3.75%, 11.39%, and 1.15%, respectively. The regular medication-taking rate among patients registered in the western region was significantly lower than that in the eastern and central areas ( F=6.317, P=0.005). According to the diagnosis, the duration of the untreated period of patients registered in 2020 with schizophrenia, bipolar disorder, delusional disorder, schizoaffective disorder, psychotic disorder with epilepsy, mental retardation with psychotic symptoms were 2.69, 3.28, 1.68, 1.92, 4.70, and 9.89 years respectively, which were shorter than patients registered in 2019. Conclusion:The number of registered patients was sustainably growing. The untreated periods of newly registered patients were considerably shorter. The services and treatment situations improved in 2020. Appropriate policies should be developed to address the weaknesses of local mental health services in the western region to improve treatment rates.

Objectives:To analyze the allocation of mental health resources in Chinese mainland and the change of these resources during the 13 th Five-year Mental Health Plan period. This analysis will serve as evidence for developing future national mental health prevention and control policies. Methods:The National Mental Health Program Office created one questionnaire to survey available mental health facilities by the end of 2020. Descriptive methods were used to analyze the mental health facilities, psychiatric beds, and mental health professionals from type, sponsor, administrative level, regions, and sub-specialities.Results:By the end of 2020, 5 936 facilities were providing mental health services in Chinese mainland. 798 191 psychiatric beds (5.65 beds/10 000 persons), 50 124 psychiatrists (3.55/100 000 persons), and 139 642 registered nurses (9.89/100 000 persons) were located in these facilities. Of all these 5 936 mental health facilities, 649 (1.09%) had geriatric psychiatric wards, 312 (0.53%) had child psychiatric wards, and 1 548 (26.08%) had rehabilitation departments. 350 counties (12.31%) had no mental health facilities and 883 counties (31.05%) had no psychiatric beds in Chinese mainland, mainly in the mid-western regions. The numbers of psychiatric beds, psychiatrists, and registered nurses per unit land area in the western region were about 4 times lower than those in the middle region and 7-11 times lower than those in the eastern region.Conclusions:The mental health resources in Chinese mainland increased significantly from 2015 to 2020, but there are still the problems of uneven geographical allocation of resources and lagged sub-specialities development. While formulating the construction and development plan for mental health prevention and control system in the future, we should further develop the mental health resources at the county level, and vigorously support to establish of mental health sub-specialities for the elderly and children, as well as mental health rehabilitation, particularly in the mid-western regions.

Sugarcane molasses containing large amounts of sucrose is an economical substrate for succinic acid production. However, Escherichia coli AFP111 cannot metabolize sucrose although it is a promising candidate for succinic acid production. To achieve sucrose utilizing ability, we cloned and expressed cscBKA genes encoding sucrose permease, fructokinase and invertase of non-PTS sucrose-utilization system from E. coli W in E. coli AFP111 to generate a recombinant strain AFP111/pMD19T-cscBKA. After 72 h of anaerobic fermentation of the recombinant in serum bottles, 20 g/L sucrose was consumed and 12 g/L succinic acid was produced. During dual-phase fermentation comprised of initial aerobic growth phase followed by anaerobic fermentation phase, the concentration of succinic acid from sucrose and sugarcane molasses was 34 g/L and 30 g/L, respectively, at 30 h of anaerobic phase in a 3 L fermentor. The results show that the introduction of non-PTS sucrose-utilization system has sucrose-metabolizing capability for cell growth and succinic acid production, and can use cheap sugarcane molasses to produce succinic acid.

Sugarcane bagasse modified by polyethylenimine (PEI) and glutaraldehyde (GA) was used as a carrier to immobilize Clostridium acetobutylicum XY16 in the process of butanol production. The effects of chemically modified sugarcane bagasse on batch and repeat-batch fermentations were investigated. Batch fermentation was conducted with an addition of 10 g/L modified sugarcane bagasse and 60 g/L glucose, resulting in a high solvent concentration of 21.67 g/L and productivity of 0.60 g/(L x h) with the treatment of 4 g/L PEI and 1 g/L GA. Compared to the fermentations by free cells and immobilized cells on unmodified sugarcane bagasse, the productivity increased 130.8% and 66.7%, respectively. The fibrous-bed bioreactor also maintained a stable butanol production during repeat-batch fermentations, achieving a maximum productivity of 0.83 g/(L x h) with a high yield of 0.42 g/g.
