ObjectiveTo construct a competency model for "dual-qualified" teachers in vocational undergraduate rehabilitation therapy programs based on the World Health Organization's rehabilitation competency framework (RCF) and relevant domestic and international standards, and explore the training pathways for rehabilitation therapy teachers in China. MethodsLiterature analysis and comparative research methods were employed to systematically review RCF, physiotherapist-education-framework-FINAL, the Minimum-Standards-for-the-Education-of-Occupational-Therapists, and the "dual-qualified" teacher standards in vocational education for China. Focusing on the characteristics of vocational undergraduate talent cultivation, it took the integration of the "educator-clinical rehabilitation therapist" dual roles as its starting point, combining rehabilitation industry competence with educator standards as its basic principle, and using RCF as its foundational dimension. It then integrated advanced competency dimensions required of vocational undergraduate teachers to form a dimensional framework. Following the systematic curriculum development concept of the work process, the core activities of each dimension were designed by combining, improving and expanding the concept integration method, and describing the ability characteristics in a graded and progressive manner, to construct a model. ResultsThis model was guided by the core concepts of three types of values ​​and four types of professional beliefs. Vertically, it encompassed 28 activities across eight competency dimensions, including teaching practice, rehabilitation practice, digital literacy, professionalism, learning and development, management and leadership, applied research, and social service. Horizontally, it encompassed 53 corresponding competency characteristics across three advanced levels (beginner, intermediate and advanced). ConclusionThis model, through its vertical dimension design and horizontal progressive development, clearly describes the advancement of vocational undergraduate rehabilitation therapy teachers from newly hired teachers to backbone teachers and professional leaders. It not only aligns with the general requirements of the national standards for "dual-qualified" teachers in higher vocational colleges in China, but also incorporates an international perspective on rehabilitation education and practice, and possesses the characteristics of vocational undergraduate education that integrates multiple abilities and roles. At the theoretical level, it provides core theoretical support for establishing standardized and internationalized "dual-qualified" teacher standards for vocational undergraduate rehabilitation therapy programs in China; at the practical level, it serves as an "action map" for teacher professional development, assessment and evaluation, providing a key reference for constructing a systematic high-end skilled rehabilitation talent training system.

Objective: To investigate the protective effect of vitamin D3 on alcoholic liver injury in mice. Methods: Forty mice were randomly divided into 4 groups : normal Control (Control) group , vitamin D3 (VitD3 ) group , alcohol model (EtOH) group and alcohol + vitamin D3 (EtOH + VitD3 ) group. The mice were fed with the DeCarlialcohol liquid diet to establish alcoholic liver injury model. Serum levels of alanine aminotransferase (ALT) , aspartate aminotransferase (AST) and liver index were detected. HE staining was used to observe the pathological changes of liver. The relative expression levels of tumor necrosis factor α (TNF⁃α ) , transforming growth factor β (TGF⁃β) , interleukin⁃6 (IL⁃6) and interleukin⁃1β (IL⁃1β) mRNA were detected by quantitative real⁃time PCR (qRT⁃PCR) . The expressions of nuclear factor⁃kappa B (NF⁃κB) p65 and NF⁃κB p50 in liver were detected by Western blot. Results: The serum ALT , AST vitality , liver index and hepatic TNF⁃α , TGF⁃ β , IL⁃6 and IL⁃1β mRNA in EtOH group were significantly higher than those in Control group. EtOH group disorganized hepatocyte and hepatic lobules boundary was not clear, and the hepatocytes showed apparent inflammatory cells infiltration of liver cells and fat cavitation. NF⁃κB p65 and NF⁃κB p50 protein expression increased significantly. Compared with EtOH group ,the serum ALT , AST vitality , liver index and hepatic TNF⁃α , TGF⁃ β , IL⁃6 and IL⁃1β mRNA in EtOH + VitD3 group decreased significantly. The pathological staining results showed that inflammatory cells infiltration and decrease in the number of fat vacuoles , and the liver cells returned to normal liver cell structure. At the same time the NF⁃κB p65 and NF⁃κB p50 protein expression level decreased significantly. Conclusion Vitamin D3 has a certain protective effect on alcohol⁃induced liver injury in mice , and its main mechanisms are related to the inhibition of NF⁃κB pathway and the reduction of inflammatory response.

Gallstone is a common surgical disease. The factors which related to intestine during the process of gallstone formation have attracted increasing attention. The main factors affecting the formation of cholesterol gallstone including cholesterol absorption, bile acid concentration, gut microbiota changing, are all related to the intestine. A correct understanding of the factors related to intestine during gallstone formation is helpful for the prevention and treatment of gallstone disease. In future, different targets related to intestine may play an important role in both prevention of gallstone disease and post-cholecystectomy management.

Retinal pigment epithelial (RPE) is primarily impaired in age-related macular degeneration (AMD), leading to progressive loss of photoreceptors and sometimes choroidal neovascularization (CNV). mTOR has been proposed as a promising therapeutic target, while the usage of its specific inhibitor, rapamycin, was greatly limited. To mediate the mTOR pathway in the retina by a noninvasive approach, we developed novel biomimetic nanocomplexes where rapamycin-loaded nanoparticles were coated with cell membrane derived from macrophages (termed as MRaNPs). Taking advantage of the macrophage-inherited property, intravenous injection of MRaNPs exhibited significantly enhanced accumulation in the CNV lesions, thereby increasing the local concentration of rapamycin. Consequently, MRaNPs effectively downregulated the mTOR pathway and attenuate angiogenesis in the eye. Particularly, MRaNPs also efficiently activated autophagy in the RPE, which was acknowledged to rescue RPE in response to deleterious stimuli. Overall, we design and prepare macrophage-disguised rapamycin nanocarriers and demonstrate the therapeutic advantages of employing biomimetic cell membrane materials for treatment of AMD.

Objective:To investigate the relationship between TP53 gene mutation and overall survival (OS) time of myelodysplastic syndrome (MDS).Methods:Databases, including PubMed, Cochrane Library and Embase were searched for relevant studies published up to 20 October, 2019. The corresponding hazard ratio ( HR) and their 95% confidence interval ( CI) for OS from multivariate Cox proportional hazard models were extracted. The combined HR with their 95% CI was calculated by using fixed or random effect models. Meta-analysis was performed by using Revman 5.3 software. Results:A total of 1 033 patients from 6 studies were enrolled. Meta-analysis results showed that OS time in TP53 gene mutation group was shorter than that in wild type group for patients with MDS ( HR = 2.16, 95% CI 1.52-3.07, P < 0.01). The prognostic risk for post-transplantation patients with MDS ( HR = 2.69, 95% CI 1.63-4.43, P < 0.01) was lower compared with that for patients treated by azacitidine( HR = 2.89, 95% CI 1.37-6.08, P = 0.005). Conclusion:TP53 gene mutation is a risk factor affecting OS of MDS patients.

Objective: To investigate the clinical effects of Qinghuang powder, low-intensity chemotherapy and Qinghuang powder alternated with low-intensity chemotherapy in the treatment of elderly acute myeloid leukemia patients progressed from myelodysplastic syndromes (MDS-AML). Methods: A total of 32 elderly patients with MDS-AML treated in Xiyuan Hospital, China Academy of Chinese Medical Sciences from January 2014 to December 2017 were retrospectively analyzed. Of them, 12 patients received Qinghuang powder (Qinghuang powder group), 6 patients received Qinghuang powder alternated with low-intensity chemotherapy (alternating group), and 14 patients received low-intensity chemotherapy (low-intensity chemotherapy group), based on the real world of patient's voluntary choice of treatment. The efficacy and adverse reactions in the 3 groups were observed. Results: The overall response number of Qinghuang powder, alternating, and low-intensity chemotherapy groups were 2, 2 and 4 cases, respectively, there was no significant difference among the 3 groups (P > 0.05). The median overall survival time of 3 groups were 14, 12 and 8 months, respectively, there was no significant difference among the 3 groups (P > 0.05). Two cases in Qinghuang powder group presented with gastrointestinal reactions; 3 cases in alternating group with myelosuppression, 2 cases with liver function damage, and 2 cases with gastrointestinal reaction; 11 cases in low-intensity chemotherapy group presented with bone marrow suppression, 3 cases with liver function damage, 7 cases with gastrointestinal reactions, and 2 cases with myocardial enzyme changes. The incidences of myelosuppression, liver function damage and myocardial enzyme changes in Qinghuang powder group were lower than those in the alternating group and low-intensity chemotherapy group. Conclusion The efficacy of Qinghuang powder or Qinghuang powder alternated with low-intensity chemotherapy for the treatment of elderly MDS-AML is not worse than the low-intensity chemotherapy, furthermore Qinghuang powder or Qinghuang powder alternated with low-intensity chemotherapy has fewer adverse reactions and better tolerance.

Objective To investigate the survival of oral arsenic-containing Qinghuang Powder (QHP) and low intensive chemotherapy (LIC) in the treatment of elderly patients with acute myeloid leukemia (AML).Methods Forty-two AML patients older than 60 years in Xiyuan Hospital from January 2015 to December 2017 were retrospectively analyzed.Of them,20 cases were treated with QHP (QHP group),22 cases were treated with LIC (LIC group).The survivals of the two groups were compared.Results There was no significant difference of median survival time (13 months vs.13.5 months,x2 =0.096,P =0.757),1-year survival rates (59.1％ vs.70.0 ％,x2 =0.543,P =0.461),2-year survival rates (13.6 ％ vs.15.0 ％,x2 =0.016,P ＞ 0.05),and 3-year survival rates (4.6 ％ vs.5.0 ％,x2 =0.005,P ＞ 0.05) between LIC and QHP groups.There was no significant difference of median survival time in age ≥75 year (12 months vs.12.5 months,x2 =1.317,P =0.251),performance status scores ＞ 2 (12 months vs.12 months,x2 =0.834,P =0.361),hematopoietic stem cell transplantation with combined disease index ＞ 2 (12 months vs.13 months,x2 =1.726,P =0.189),secondary AML (10 months vs.14 months,x2 =1.552,P =0.213),and poor cytogenetics (12 months vs.8 months,x2 =0.479,P =0.489) between LIC and QHP group.Conclusion The survival of elderly AML patients is considerable in patients treated with oral QHP and LIC,which suggests that oral QHP may be an equivalent alternative treatment since elderly AML (especially more than 75 years) patients refused to LIC therapy.
