Objective To analyze the cerebral angiographic characteristics of patients with central retinal artery occlusion(CRAO)and to study their prognosis.Methods A retrospective study was conducted,with 182 CRAO patients enrolled,who were treated at Xuanwu Hospital,Capital Medical University,the First Affiliated Hospital of Anhui Medical University,the Affiliated Suzhou Hospital of Anhui Medical University,and the People's Hospital of Shihezi City from January 1,2014,to June 1,2024.All patients underwent cerebral angiography within one month of onset.The baseline characteristics,treatment details,and follow-up data were collected.The Spearman rank correlation coefficient was used to evaluate the correlation between the characteristics of the ophthalmic artery and the ipsilateral carotid artery angiography,and Logistic regression analysis was performed to explore factors related to patient prognosis.Results Cerebral angiography results showed that 81.3％of patients had ocular blood supply from the ipsilateral internal carotid artery,12.1％from the ipsilateral external carotid artery,and 6.6％from the ipsilateral middle cerebral artery.Among the patients,80(44.0％)had varying degrees of stenosis or occlusion of the affected ophthalmic artery,with 69 patients(86.3％)showing stenosis at the origin of the ophthalmic artery.Additionally,135 patients(74.2％)had varying degrees of stenosis or occlusion of the ipsilateral carotid artery,with 110 patients(60.4％)showing stenosis at the carotid bulb,88 patients(48.3％)having unilateral carotid lesions,and 41 patients(22.5％)having multiple lesions.Correlation analysis indicated a significant correlation between the degree of stenosis in the ophthalmic artery and the carotid artery(r=0.76,P=0.006).Univariate and multivariate Logistic regression analyses revealed that the time from symptom onset to hospital admission(OR=0.93,95％CI:0.85-0.98,P=0.018),the grading of oxygenation-based hypoperfusion maculopathy(OHM)(OR=3.12,95％CI:1.09-6.34,P=0.005),intravenous thrombolysis(IVT)(OR=2.75,95％CI:1.08-5.35,P=0.031),and the absence of stenosis in the ophthalmic artery(OR=1.33,95％CI:1.02-3.41,P=0.026)were independent predictors of prognosis for CRAO patients.Conclusions The degree of stenosis in the ophthalmic artery is significantly correlated with the degree of stenosis in the carotid artery in CRAO patients.Time from symptom onset to hospital admission,OHM grading,IVT,and the absence of stenosis in the ophthalmic artery are independent factors influencing the prognosis of CRAO patients.

Objective:To explore the internal mechanism by which self-evaluation influences non-suicidal self-injury (NSSI) in adolescent patients with depressive disorder.Methods:Clinical data from 214 adolescent patients with depressive disorder hospitalized at Suzhou Guangji Hospital from March 2022 to January 2024 were prospectively collected. According to the DSM-5 diagnostic criteria for NSSI, participants were divided into an NSSI group (158 cases [38 males, 120 females, age 12-17 (14.2±1.5) years]) and a non-NSSI group (56 cases [20 males, 36 females, age 12-18 (14.5±1.8) years]). A self-developed basic information questionnaire was used to collect demographic data. Standardized tools including the Self-rating Depression Scale (SDS), Inventory of Parent and Peer Attachment (IPPA), Self-acceptance Questionnaire (SAQ), and Perceived Stress Scale-10 (PSS-10) were used to assess their depression level, parental attachment level, self-evaluation/acceptance level, perceived stress level, and other relevant psychological characteristics. Differences in psychological characteristics between the two groups were compared. Logistic regression, correlation analysis, and mediation effect models were used to explore the relationships between variables and NSSI and their mechanisms.Results:The NSSI group had significantly higher total scores on the SDS (41.3±7.7 vs. 34.4±9.3) and PSS-10 (25.5±6.1 vs. 21.3±6.5) than the non-NSSI group ( F=29.12, F=18.17, respectively; all P<0.001). Conversely, the NSSI group had significantly lower total scores on the SAQ (31.2±8.8 vs. 35.9±8.9) and IPPA (56.3±13.6 vs. 63.4±13.8) compared to the non-NSSI group ( F=11.24, F=10.84, respectively; all P<0.001). Stepwise logistic regression analysis identified depression level (SDS total score, OR=1.12, 95% CI: 1.05-1.19), self-evaluation (SAQ subscale score, OR=1.17, 95% CI: 1.04-1.31), and perceived stress (PSS-10 total score, OR=1.11, 95% CI: 1.01-1.22) as predictors of NSSI (all P<0.05). Chain mediation analysis showed that self-evaluation had a significant positive direct effect ( β=0.025, P<0.01) and a negative indirect effect ( β=-0.038, P<0.001) on NSSI, with a negative total effect ( β=-0.012, P<0.05). The indirect effect was realized through three pathways: a single mediation pathway of self-evaluation via perceived stress ( β=-0.016), a single mediation pathway of self-evaluation via depression ( β=-0.011), and a chain mediation pathway of self-evaluation via perceived stress and depression ( β=-0.011) (all P<0.05). Conclusion:Self-evaluation influences NSSI behavior through a dual mechanism involving both direct and indirect effects. The indirect protective effect is primarily achieved by reducing perceived stress and depression levels.

Intraoperative cell salvage (IOCS) has been widely applied as an important blood conservation measure in surgical operations. However, there is currently a lack of clinical practice guidelines for the implementation of IOCS in patients with malignant tumors. This report aims to provide clinicians with recommendations on the use of IOCS in patients with malignant tumors based on the review and assessment of the existed evidence. Data were derived from databases such as PubMed, Embase, the Cochrane Library and Wanfang. The guideline development team formulated recommendations based on the quality of evidence, balance of benefits and harms, patient preferences, and health economic assessments. This study constructed seven major clinical questions. The main conclusions of this guideline are as follows: 1) Compared with no perioperative allogeneic blood transfusion (NPABT), perioperative allogeneic blood transfusion (PABT) leads to a more unfavorable prognosis in cancer patients (Recommended); 2) Compared with the transfusion of allogeneic blood or no transfusion, IOCS does not lead to a more unfavorable prognosis in cancer patients (Recommended); 3) The implementation of IOCS in cancer patients is economically feasible (Recommended); 4) Leukocyte depletion filters (LDF) should be used when implementing IOCS in cancer patients (Strongly Recommended); 5) Irradiation treatment of autologous blood to be reinfused can be used when implementing IOCS in cancer patients (Recommended); 6) A careful assessment of the condition of cancer patients (meeting indications and excluding contraindications) should be conducted before implementing IOCS (Strongly Recommended); 7) Informed consent from cancer patients should be obtained when implementing IOCS, with a thorough pre-assessment of the patient's condition and the likelihood of blood loss, adherence to standardized internally audited management procedures, meeting corresponding conditions, and obtaining corresponding qualifications (Recommended). In brief, current evidence indicates that IOCS can be implemented for some malignant tumor patients who need allogeneic blood transfusion after physician full evaluation, and LDF or irradiation should be used during the implementation process.

ObjectiveTo investigate the influence of histone deacetylase 3 (HDAC3) on the occurrence, development of psoriasis-like inflammation in mice, and the relative immune mechanisms. MethodsHealthy C57BL/6 mice aged 6-8 weeks were selected and randomly divided into 3 groups: control group (Control), psoriasis model group (IMQ), and HDAC3 inhibitor RGFP966-treated psoriasis model group (IMQ+RGFP966). One day prior to the experiment, the back hair of the mice was shaved. After a one-day stabilization period, the mice in Control group was treated with an equal amount of vaseline, while the mice in IMQ group was treated with imiquimod (62.5 mg/d) applied topically on the back to establish a psoriasis-like inflammation model. The mice in IMQ+RGFP966 group received intervention with a high dose of the HDAC3-selective inhibitor RGFP966 (30 mg/kg) based on the psoriasis-like model. All groups were treated continuously for 5 d, during which psoriasis-like inflammation symptoms (scaling, erythema, skin thickness), body weight, and mental status were observed and recorded, with photographs taken for documentation. After euthanasia, hematoxylin-eosin (HE) staining was used to assess the effect of RGFP966 on the skin tissue structure of the mice, and skin thickness was measured. The mRNA and protein expression levels of HDAC3 in skin tissues were detected using reverse transcription real-time quantitative polymerase chain reaction (RT-qPCR) and Western blot (WB), respectively. Flow cytometry was employed to analyze neutrophils in peripheral blood and lymph nodes, CD4⁺ T lymphocytes, CD8⁺ T lymphocytes in peripheral blood, and IL-17A secretion by peripheral blood CD4⁺ T lymphocytes. Additionally, spleen CD4⁺ T lymphocyte expression of HDAC3, CCR6, CCR8, and IL-17A secretion levels were analyzed. Immunohistochemistry was used to detect the localization and expression levels of HDAC3, IL-17A, and IL-10 in skin tissues. ResultsCompared with the Control group, the IMQ group exhibited significant psoriasis-like inflammation, characterized by erythema, scaling, and skin wrinkling. Compared with the IMQ group, RGFP966 exacerbated psoriasis-like inflammatory symptoms, leading to increased hyperkeratosis. The psoriasis area and severity index (PASI) skin symptom scores were higher in the IMQ group than those in the Control group, and the scores were further elevated in the IMQ+RGFP966 group compared to the IMQ group. Skin thickness measurements showed a trend of IMQ+RGFP966>IMQ>Control. The numbers of neutrophils in the blood and lymph nodes increased sequentially in the Control, IMQ, and IMQ+RGFP966 groups, with a similar trend observed for CD4⁺ and CD8⁺ T lymphocytes in the blood. In skin tissues, compared with the Control group, the mRNA and protein levels of HDAC3 decreased in the IMQ group, but RGFP966 did not further reduce these expressions. HDAC3 was primarily located in the nucleus. Compared with the Control group, the nuclear HDAC3 content decreased in the skin tissues of the IMQ group, and RGFP966 further reduced nuclear HDAC3. Compared with the Control and IMQ groups, RGFP966 treatment decreased HDAC3 expression in splenic CD4⁺ and CD8⁺ T cells. RGFP966 treatment increased the expression of CCR6 and CCR8 in splenic CD4⁺ T cells and enhanced IL-17A secretion by peripheral blood and splenic CD4⁺ T lymphocytes. Additionally, compared with the IMQ group, RGFP966 reduced IL-10 protein levels and upregulated IL-17A expression in skin tissues. ConclusionRGFP966 exacerbates psoriatic-like inflammatory responses by inhibiting HDAC3, increasing the secretion of the cytokine IL-17A, and upregulating the expression of chemokines CCR8 and CCR6.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

OBJECTIVE To explore the protective effect of Jianpi Shengqing Jiangzhuo Recipe on db/db mice with diabetic kid-ney disease(DKD)and its possible mechanism.METHODS Thirty-two 8-week-old male db/db mice were randomly divided into four groups(n=8),including the model group,the Western medicine group[Dapagliflozin(1.0 mg·kg-1·d-1)],low-dose Jianpi Shengqing Jiangzhuo group(19.63 g·kg-1·d-1),and high-dose Jianpi Shengqing Jiangzhuo group(58.89 g·kg-1·d-1).Addi-tionally,8 db/m mice were used as the normal group.The mice were orally administered once a day for 10 consecutive weeks.The general survival status of the mice was observed,and the body weight,fasting blood glucose(FBG),and urine volume of the mice were dynamically monitored;urine creatinine and urine microalbumin were detected,and urine microalbumin excretion(UAE)and protein-creatinine ratio(ACR)were calculated.After the last intervention,mice were fasted for 12 h,blood was collected under anesthesia,and kidney tissue was separated;blood creatinine(Scr),serum urea nitrogen(BUN),triglycerides(TG),total cholesterol(TC),low-density lipoprotein(LDL-C),and high-density lipoprotein(HDL-C)were tested;HE and Masson staining were used to observe pathological changes in renal tissue;Oil Red O staining was used to observe the deposition of lipid droplets in the kidneys,and Image J was used for quantitative analysis;ELISA was used to detect the levels of TNF-α and IL-1β in renal tissue;Western blot was used to detect the expression of SIRT1,SREBP-1,and PPAR-α proteins in renal tissue.RESULTS Compared with the normal group mice,the body weight,FBG,Scr,TG,TC,HDL-C,LDL-C,urine volume,UAE,and ACR of the model group mice were signifi-cantly increased(P<0.05,P<0.01);the glomerular volume was significantly increased,renal fibrosis was altered,and renal lipid droplet deposition increased(P<0.01);renal TNF-α,IL-1β,SREBP-1 expression increased(P<0.01),and SIRT1 and PPAR-α expression decreased(P<0.01).Compared with the model group,the FBG levels in the Western medicine group was significantly de-creased at the 5th and 10th weeks of intervention(P<0.05,P<0.01);after the intervention,the Scr,UAE and ACR in the Western medicine group and high-dose Jianpi Shengqing Jiangzhuo group were significantly decreased(P<0.05,P<0.01),and the serum TG level in the high-dose Jianpi Shengqing Jiangzhuo group was also significantly decreased(P<0.01);the Western medicine group and the high-dose group of Jianpi Shengqing Jiangzhuo group improved renal pathological changes and lipid deposition(P<0.05,P<0.01),with decreased levels of TNF-α and IL-1β and increased expression of SIRT1 and PPAR-α proteins(P<0.05,P<0.01);high-dose group of Jianpi Shengqing Jiangzhuo decreased the expression of SREBP-1(P<0.01).CONCLUSION Jianpi Shengqing Jiangzhuo Recipe can improve proteinuria,kidney injury,renal lipid deposition as well as inflammatory reaction in DKD,which may be related to the activation of the SIRT1/SREBP-1/PPAR-α pathway to regulate lipid homeostasis.

Traditional Chinese Medicine (TCM), as a treasure of the Chinese nation, plays a significant role in maintaining public health. In 2019, the Central Committee of the Communist Party of China and the State Council proposed for the first time the establishment of a TCM registration and evaluation evidence system that integrates TCM theory, "personal experience" and clinical trials (referred to as the "Three-in-One" System) to promote the inheritance and innovation of TCM. Subsequently, the National Medical Products Administration issued several guiding principles to advance the improvement and implementation of this system. Owing to the complexity of its implementation, there are still differing understandings within the TCM industry regarding the positioning of the "Three-in-One" Registration and Evaluation Evidence System, as well as the connotation and value orientation of the "personal experience." To address this, Academician WANG Qi, President of the TCM Association, China International Exchange and Promotion Association for Medical and Healthcare and TCM master, led a group of academicians, TCM masters, TCM pharmacology experts and clinical TCM experts to convene a "Seminar on Promoting the Implementation of the ′Three-in-One′ Registration and Evaluation Evidence System for Chinese Medicinals." Through extensive discussions, an expert consensus was formed, clarifying the different roles of the TCM theory, "personal experience" and clinical trials within the system. It was further emphasized that the "personal experience" is the core of this system, and its data should be derived from clinical practice scenarios. In the future, the improvement of this system will require collaborative efforts across multiple fields to promote the high-quality development of the Chinese medicinal industry.

OBJECTIVE: This study aimed to explore the association between body mass index (BMI) and mortality based on the 10-year population-based multicenter prospective study. METHODS: A general population-based multicenter prospective study was conducted at four sites in rural China between 2013 and 2023. Multivariate Cox proportional hazards models and restricted cubic spline analyses were used to assess the association between BMI and mortality. Stratified analyses were performed based on the individual characteristics of the participants. RESULTS: Overall, 19,107 participants with a sum of 163,095 person-years were included and 1,910 participants died. The underweight (< 18.5 kg/m ²) presented an increase in all-cause mortality (adjusted hazards ratio [ aHR] = 2.00, 95% confidence interval [ CI]: 1.66-2.41), while overweight (≥ 24.0 to < 28.0 kg/m ²) and obesity (≥ 28.0 kg/m ²) presented a decrease with an aHR of 0.61 (95% CI: 0.52-0.73) and 0.51 (95% CI: 0.37-0.70), respectively. Overweight ( aHR = 0.76, 95% CI: 0.67-0.86) and mild obesity ( aHR = 0.72, 95% CI: 0.59-0.87) had a positive impact on mortality in people older than 60 years. All-cause mortality decreased rapidly until reaching a BMI of 25.7 kg/m ² ( aHR = 0.95, 95% CI: 0.92-0.98) and increased slightly above that value, indicating a U-shaped association. The beneficial impact of being overweight on mortality was robust in most subgroups and sensitivity analyses. CONCLUSION This study provides additional evidence that overweight and mild obesity may be inversely related to the risk of death in individuals older than 60 years. Therefore, it is essential to consider age differences when formulating health and weight management strategies.

Objective To investigate the role and mechanism of afzelin(AFZ)in treating Crohn's disease-like colitis.Methods A mouse model of 2,4,6-trinitrobenzene sulfonic acid-induced colitis was established to assess the effect of AFZ on experimental colitis in vivo.A Caco-2 cell model of tumor necrosis factor(TNF)-α-induced inflammation was established to evaluate the effects of AFZ on the intestinal barrier function,intestinal epithelial cell apoptosis,and mitochondrial function in vitro.The animal and cell experiments were performed to validate the regulatory role of the adenosine monophosphate-activated protein kinase(AMPK)/silent information regulater 1(SIRT1)/peroxisome proliferator-activated receptor gamma coactivator(PGC)-1α pathway in the treatment of colitis with AFZ.Results AFZ reduced the disease activity index(P=0.003),weight loss(P<0.001),colon shortening(P<0.001),inflammation score(P=0.002),pro-inflammatory cytokine release(interleukin-6:P<0.001;TNF-α:P=0.010),and intestinal barrier permeability(fluorescein isothiocyanate dextran 4:P<0.001;intestinal-type fatty acid-binding protein:P=0.013).Meanwhile,AFZ increased the colonic transepithelial electric resistance(P=0.001),reduced bacterial translocation(P<0.001),and promoted the localization and up-regulated the expression of tight junction proteins [zonula occluden-1(P=0.005) and Claudin-1(P=0.024)].AFZ exerted a protective effect on the Caco-2 cells exposed to TNF-α in terms of intestinal epithelial cell permeability(P=0.017),transepithelial electric resistance(P=0.014),and tight junction protein[zonula occluden-1(P=0.014) and Claudin-1(P=0.006)] localization and expression.Furthermore,the cell and animal experiments confirmed that AFZ reduced the percentage of apoptosis(P<0.001,P=0.013)and the expression of cleaved-caspase 3(P=0.028,P=0.004)and Bax(P=0.004,P=0.020),and upregulated the Bcl2(P=0.020,P=0.006)level in intestinal epithelial cells.Additionally,AFZ increased the number of mitochondria,mitochondrial membrane potential,and copy number of mitochondrial DNA(P=0.007)in intestinal epithelial cells,while enhancing the activities of mitochondrial respiratory chain complex Ⅰ(P=0.005)and complex Ⅳ(P=0.001).The activation of the AMPK/SIRT1/PGC-1α pathway was involved in the protective effects of AFZ on mitochondrial function and apoptosis in intestinal epithelial cells.Conclusion AFZ alleviates mitochondrial dysfunction and apoptosis in intestinal epithelial cells by activating the AMPK/SIRT1/PGC-1α pathway,thereby ameliorating intestinal barrier dysfunction and experimental colitis.
