Background The rapid development of informatization in primary care in regions inhabited by ethnic minorities during the 13th Five-Year Plan period (2016—2020) , has laid a foundation for the improvement of the serving capacity of primary care supported by information technologies, but there is a lack of research on information technology and the efficiency of primary care. Objective To assess the status including effectiveness of informatization in primary care in China asregions inhabited by ethnic minorities, to explore the impact of information technology on improving the efficiency of primary care. Methods From July to October 2020, 84 primary care institutions in 23 ethnic counties in three autonomous prefectures of Sichuan (Ganzi, Liangshan and Aba) were selected by stratified sampling, and whose directors were invited to complete a self-administered questionnaire survey for understanding the status including effectiveness of informatization in their institutions. Furthermore, the heads of local health committees and directors of primary care institutions in these ethnic counties were invited to attend a group discussion regardingthe setting of departments, service development, status of informatization and settings for information services in primary care institutions. Results In terms of software construction, of the 84 primary care institutions, 57 (67.9%) used the public health system, 44 (52.4%) used the family doctor management system, and 25 (29.8%) use the hospital information system. Forty-seven (56.0%) primary care institutions had achieved vertical connectivity with other institutions (mostly regional- and county-level institutions as well as other members in a regional medical consortium) using information technologies, and regional informatization. Institutions that had horizontal connectivity with 69 (74.4%) of the primary care institutions were medical insurance departments. Only 18 (21.4%) institutions had independent information departments, and 34 (41.0%) did not employ information professionals. Lack of information professionals〔64 (76.2%) 〕, insufficient funds〔52 (61.9%) 〕 and weak infrastructure〔51 (60.7%) 〕 were main problems revealed in informatization construction. Institutions with regional informatization, vertical connectivity with other institutions, and the construction of a hospital information platform with electronic medical record system as the core were superior to those without in terms of setting of laboratory and examination departments and provision of traditional Chinese medicine services (P

The mechanism underlying autophagy in paroxysmal nocturnal hemoglobinuria (PNH) remains largely unknown. We previously sequenced the entire genome exon of the CD59– cells from 13 patients with PNH and found genes such as CUX1 encoding Cut-like homeobox 1. Peripheral blood samples from 9 patients with PNH and 7 healthy control subjects were obtained to measure CUX1 expression. The correlation between CUX1 messenger RNA expression and PNH clinical indicators was analyzed. To simulate CUX1 expression in patients with PNH, we generated a panel of PNH cell lines by knocking out PIGA in K562 cell lines and transfected lentivirus with CUX1. CCK-8 and EDU assay assessed cell proliferation. Western blotting was used to detect Beclin-1, LC3A, LC3B, ULK1, PI3K, AKT, p-AKT, mTOR, and p-mTOR protein levels. Autophagosomes were observed with transmission electron microscopy. Chloroquine was used to observe CUX1 expression in PNH after autophagy inhibition. Leukocytes from patients with PNH had lower levels of CUX1 messenger RNA expression and protein content than healthy control subjects. The lactose dehydrogenase level and the percentage of PNH clones were negatively correlated with CUX1 relative expression. We reduced CUX1 expression in a PIGA knockout K562 cell line, leading to increased cell proliferation. Levels of autophagy markers Beclin-1, LC3B, LC3A, and ULK1 increased, and autophagosomes increased. Furthermore, PI3K/AKT/mTOR protein phosphorylation levels were lower. CUX1 expression did not change and cell proliferation decreased in CUX1 knocked down PNH cells after inhibition of autophagy by chloroquine. In brief, CUX1 loss-of-function mutation resulted in stronger autophagy in PNH. [ABSTRACT FROM AUTHOR]

Neuroglial cells have a high level of plasticity, and many types of these cells are present in the nervous system. Neuroglial cells provide diverse therapeutic targets for neurological diseases and injury repair. Cell reprogramming technology provides an efficient pathway for cell transformation during neural regeneration, while transcription factor-mediated reprogramming can facilitate the understanding of how neuroglial cells mature into functional neurons and promote neurological function recovery.
