Objective:The development and application of end-of-life patient decision aids for elderly were systematically reviewed and analyzed in order to supply guidance for the design of localized patient decision aids in China.Methods:Using the Scoping Review Guidelines as a methodological framework, a systematic search was conducted across databases including China National Knowledge Infrastructure, Wanfang, China Biology Medicine, PubMed, Web of Science, Embase, Cochrane Library, CINAHL, and BIOSIS. The search period covered from the inception of these databases to October 31, 2023. Two professionally trained researchers were responsible for screening, extracting, and organizing the retrieved literature.Results:A total of 5 studies on decision aids were included. These primarily employed paper graphics, interactive web pages, or multimedia slides as formats. The content encompassed various aspects such as palliative care options along with their pros and cons, assisting patients in clarifying their personal values, encouraging patients to document their decision-making preferences, and initiating end-of-life conversations with family members. Age-friendly design strategies were adopted in 4 studies; efficacy was validated in 3 studies, and in two of these studies, significant improvements were observed in engagement of patients (or substitute decision-makers) in ACP and the consistency of decision preferences (both P< 0.05). Conclusions:End-of-life decision aids for elderly patients can improve decision-making outcomes to some extent, however, the form and quality standards of them need to be improved, and their long-term effect needs further research and verification. It is recommended that in the future, the needs for end-of-life decision-making should be properly assessed based on the health literacy level, and high-quality localized end-of-life decision aids should be developed and popularized.

ObjectiveTo explain the scientific connotation of Morindae Officinalis Radix （MOR） processed by Glycyrrhizae Radix et Rhizoma （Gly） by comparing the effect of raw products of MOR and processed products of MOR with different proportions of Gly （GMOs） on the improvement of renal function and hypothalamic-pituitary-gonadal （HPG） axis， the protein expression of Wnt/β-catenin and transforming growth factor-β₁ （TGF-β₁）/Smad signal pathways in kidney Yang deficiency model rats induced by adenine. MethodGMOs were prepared according to method under MOR in 2020 edition of Chinese Pharmacopoeia. Rat model of kidney Yang deficiency was established by intragastrical administration of adenine， levels of follicle stimulating hormone （FSH）， luteinizing hormone （LH）， estradiol （E₂） and testosterone （T） were measured by enzyme-linked immunosorbent assay （ELISA）. Levels of urea nitrogen （BUN） and serum creatinine （SCr） were measured by spectrophotometry， hematoxylin-eosin （HE） staining was used to evaluate the pathological changes of kidney， testis and epididymis. Immunohistochemistry （IHC） was used to analyze the protein expression of E-cadherin， α-smooth muscle actin （α-SMA）， Wnt2b， β-catenin， Smad1 and Smad4. ResultMOR processed with 100∶6 and 100∶12 proportions of Gly （short for GMO/100∶6 and GMO/100∶12） had the most obvious improvement on the body posture of kidney Yang deficiency model rats. GMO/100∶12 had the best effect on reducing the levels of BUN， SCr， FSH， LH and the ratio of E₂/T. GMO/100∶6 and GMO/100∶12 had the best effect on regulating the protein expression of E-cadherin， α-SMA， Wnt2b， β-catenin， Smad1 and Smad4. ConclusionGMO/100∶6 and GMO/100∶12 have the a good effect on the improvement of renal function and HPG axis in kidney Yang deficiency model rats induced by adenine， which is related with the fact that they can regulate Wnt/β-catenin pathway in renal and testicular tissue and TGF-β₁/Smads pathway in testicular tissue.

Senescence of activated hepatic stellate cells (aHSCs) is a stable growth arrest that is implicated in liver fibrosis regression. Senescent cells often accompanied by a multi-faceted senescence-associated secretory phenotype (SASP). But little is known about how alanine-serine-cysteine transporter type-2 (ASCT2), a high affinity glutamine transporter, affects HSC senescence and SASP during liver fibrosis. Here, we identified ASCT2 is mainly elevated in aHSCs and positively correlated with liver fibrosis in human and mouse fibrotic livers. We first discovered ASCT2 inhibition induced HSCs to senescence in vitro and in vivo. The proinflammatory SASP were restricted by ASCT2 inhibition at senescence initiation to prevent paracrine migration. Mechanically, ASCT2 was a direct target of glutaminolysis-dependent proinflammatory SASP, interfering IL-1α/NF-κB feedback loop via interacting with precursor IL-1α at Lys82. From a translational perspective, atractylenolide III is identified as ASCT2 inhibitor through directly bound to Asn230 of ASCT2. The presence of -OH group in atractylenolide III is suggested to be favorable for the inhibition of ASCT2. Importantly, atractylenolide III could be utilized to treat liver fibrosis mice. Taken together, ASCT2 controlled HSC senescence while modifying the proinflammatory SASP. Targeting ASCT2 by atractylenolide III could be a therapeutic candidate for liver fibrosis.

Objective:To establish risk stratifying criteria for acute rejection(AR)after kidney transplantation(KT)through analyzing the preoperative risk factors of KT recipients from deceased donor(DD).Methods:A retrospective study is conducted for 1 382 KT recipients of DD kidney at First Affiliated Hospital of Xi'an Jiaotong University from January 2015 to December 2020.According to the presence or absence of AR within 1 year post-KT, they are divided into two groups of acute rejection(group AR, 115 cases)and non-rejection(group non-AR, 1 267 cases). Clinical data of two groups are examined by univariate and multivariate analyses for determining the risk factors of AR and a scoring standard is established on the basis of regression coefficients.They are divided into three groups of low-risk(907 cases), middle-risk(450 cases)and high-risk(25 cases)according to the scoring results and the incidence of AR is compared among different scoring groups.Results:Univariate analysis indicates that donor age(AR, 793 cases; non-AR, 474 cases, P=0.033), age difference between recipients and donors≥25 years(AR, 63 cases; non-AR; 315 cases; P<0.001), recipient panel-reactive antibodies(PRA)plus donor-specific antibody(DSA)(+ )(AR, 96 cases; non-AR, 1 169 cases, P=0.002), donor kidney cold ischemic time≥12h(AR, 81 cases; non-AR, 1 064 cases, P<0.001), donor/recipient HLA mismatch≥3(AR, 70 cases; non-AR, 984 cases, P<0.001)and expanded criteria donor(ECD)(AR, 50 cases; non-AR, 790 cases, P<0.001)are high risk factors for AR(all P<0.05). Variables with statistical significance during univariate analysis are included for multivariate analysis.Five variables are finally determined, including age difference between recipients and donors≥25 years(β=0.61, P=0.006), PRA+ DSA(+ )(β=0.74, P=0.008), donor kidney cold ischemic time≥12 h(β=0.74, P<0.001), HLA mismatch(≥3)(β=0.81, P<0.001)and ECD(β=0.82, P<0.001). Score for each risk factor is calculated according to the relevant regression coefficient and scoring standard formulate on the basis of the above five risk factors with a total score of 36.With an overall incidence of AR at 8.32%(115/1 382), the incidence of AR is 4.3%, 14.7% and 40.0% in low/middle/high-risk group and the difference is statistically significant.It hints that immune risk stratification can effectively determine the risk of postoperative AR for KT recipients.The incidence of AR is significantly higher in middle/high-risk group than that in low-risk group ( P<0.001). Conclusions:For recipients with middle/high immune risk, intensity and dose of immunosuppressants should be appropriately boosted during preoperative induction and maintenance period.And the occurrences of AR and infection should be dynamically monitored.

MRI technology has been widely used in brain connectivity analysis to explore the neurobiological mechanism of ASD. Analysis of brain structural connectivity found atypical growth and development in patients with ASD, excessive growth in infancy, and excessive decline in functions from adolescence to middle age. Functional connectivity analysis suggests that default mode network (DMN) may be related to theory of mind (ToM) and self-referential processing, abnormal salience network (SN) connections can lead to social communication disorders, and abnormal reward network (RN) may be related to repetitive and restricted behaviors. Effective connectivity analysis found that information transmission between brain regions was abnormal in ASD patients, which was associated with social dysfunction. This article introduces the latest development of MRI research, and discusses the differences between ASD patients and normal human brain connections, so as to provide theoretical reference for further investigations of the neural activity mechanism of ASD patients.
