RESUMEN
Aim To study the effect of H2S synthase CBS-derived H2S from mouse nerve cells on the proliferation and migration of the brain vascular endothelial cells and its relationship with VEGFR2. Methods CCK-8 method was used to detect cell proliferation, cell scratch method and Transwell method were used to detect cell migration, methyl blue method was used to detect H2S content, and calcium fluorescence imaging method was used to detect intracellular free Ca2 + concentration. HT22 cells were co-cultured with bEnd. 3 cells by using Transwell system. Results The H2S donor NaHS( 1 xlO"8-1 X 10"3'5 mol • L'1) significantly increased the proliferation and migration of HU- VEC cells and bEnd. 3 cells, while the VEGFR2 blocker SU5416 (10 (xmol • L"1) markedly inhibited the NaHS- increased proliferation and migration; in the co-culture system,the substrate of H2S synthase CBS, L-Cys (100 |xmol • L"1) , significantly promoted the proliferation and migration of bEnd. 3 cells, and increased intracellular Ca2 + fluorescence intensity in bEnd. 3 cells and the H2S content in the co-culture. However, CBS inhibitor AO A A (1 mmol • L"1 ) and SU5416 significantly attenuated the effects of L-Cys on the proliferation and migration and intracellular Ca2 + fluorescence intensity. Conclusions The CBS-derived H2S from neurons can promote the proliferation and migration of mouse cerebral vascular endothelial cells, which may be related to activation of VEGFR2 and subsequently increase of intracellular free Ca2+ concentration.
RESUMEN
Objective:To explore the characteristics and related factors of unmet needs of nursing care and service for adults with extremely severe and severe intellectual disabilities. Methods:A total of 127 547 adults with extremely severe and severe intellectual disabilities were sampled. Descriptive statistics and multiple response analysis were conducted, and a structural equation model of unmet needs of nursing care and received the services was developed. Results:A total of 26 038 adults with extremely severe and severe intellectual disabilities reported unmet needs of rehabilitation, including nursing care (52.50%), medicine (36.90%), assistive device (20.90%), functional training (19.70%) and surgery (0.80%) respectively. A total of 11 640 adults with extremely severe and severe intellectual disabilities reported received rehabilitation services, including nursing care (49.90%), medicine (36.80%), functional training (19.10%), assistive device (14.10%) and surgery (1.00%) respectively. The structural equation model showed that received nursing care service (main effect = 0.646) and received rehabilitation services (included nursing care) (main effect = 0.014), age (main effect = 0.031), household registration (main effect = 0.015) and educational level (main effect = -0.158) had effects on unmet needs of nursing care (P < 0.001). Conclusion:Adults with extremely severe and severe intellectual disabilities reported unmet needs mainly involved in field of nursing care, and their rehabilitation services mapped to their main needs. It proposed to develop rehabilitation services tailored to their rehabilitation experience, age, socioeconomic status, functional conditions and characteristic of unmet needs, to develop accessible services items and individualized nursing care programs, and to expand the nursing care service supply and coverage of nursing care.
RESUMEN
Objective:To explore the characteristics and the influential factors of unmet needs and services development of rehabilitation for people with extremely severe hearing disability (PSHDs). Methods:A total of 90 052 PSHDs were included. Multiple response was used to analyze the characteristics of unmet needs and services of rehabilitation. The structural equation model of the received service and unmet needs of PSHDs was developed. Results:The reporting rate of unmet needs of rehabilitation for PSHDs, from high to low, were assistive devices (61.5%), nursing care (24.1%), medicine (23.4%), functional training (17.6%) and surgery (2.5%). The reporting rate of received service for PSHDs, from high to low, were assistive devices (58.3%), nursing care (24.4%), medicine (22.4%), functional training (22.0%) and surgery (2.2%). Structural Equation Model showed that the more services received, the more needs for cochlear implantation surgery and speech therapy (P < 0.001); the better family income situation, the more needs for cochlear implantation surgery (P < 0.001); and age factor had significant effects on the unmet needs of cochlear implantation surgery and speech therapy (P < 0.001). Conclusion:PSHDs reported unmet needs and received services mainly included assistive devices, nursing care, medicine and functional rehabilitation training. Those PSHDs who had received services would report more demand of unmet needs, supposed that improving the accessibility and coverage of services should be emphasized in the development of rehabilitation services. According to ICF model, on the basis of the characteristics of the unmet needs of PSHDs, it proposed to take measures to implement precise rehabilitation services to improve the quality of services.

RESUMEN
Large quantity of activated sludge is generated from wastewater treatment but without yet an appropriate deposition. High temperature can lyse the activate sludge so that nitrogen and phosphorus containing nutrients are released. Halomonas CJN was found to grow on the heat lysed activated sludge and glucose for production of bioplastic poly-3-hydroxybutyrate (PHB) in the absence of yeast extract, nitrogen and phosphorus sources as well as trace elements. This reduces the PHB production cost significantly. Furthermore, acetic acid formed from anaerobic fermentation of heat lysed activated sludge can be used to replace glucose for cell growth but not much for PHB production. After construction of an additional PHB synthesis pathway in Halomonas CJN, we can produce PHB entirely from heat lysed activated sludge, reducing production cost of PHB roughly from ¥ 30 000 Yuan/ton to ¥ 20 000 Yuan/ton, thus turning waste activated sludge to valuable raw material resource.
