ObjectiveRetinal vein occlusion （RVO） is the second most common vascular disease leading to vision loss. Since its pathogenesis remains unclear， current Western medical treatments primarily target complications such as macular edema and neovascularization. The main therapeutic approaches include intravitreal injections of anti-vascular endothelial growth factor （VEGF） agents or corticosteroids， laser photocoagulation， and pars plana vitrectomy. However， these treatments cannot fully reverse disease progression or structural damage. Traditional Chinese medicine （TCM） has unique advantages in the clinical diagnosis and treatment of RVO， and integrated Chinese and Western medicine approaches may offer better clinical outcomes. This study， based on the clinical manifestations of RVO， systematically reviews the existing literature and evaluates the alignment of current RVO animal models with clinical manifestations. The aim is to identify the characteristics and limitations of existing models and provide recommendations and prospects for developing RVO animal models featuring the combination of disease and syndrome. MethodsDatabases including CNKI， Wanfang Data， PubMed， and Web of Science were searched with the keywords of "retinal vein occlusion" and "animal model". Model characteristics were assessed based on the diagnostic criteria for diseases and syndromes in both TCM and Western medicine. The alignment of each model with clinical manifestations was analyzed and evaluated. ResultsThe available RVO models were primarily established via methods such as laser photocoagulation， photodynamic therapy， diathermy， intravitreal drug injection， and mechanical modeling. These models demonstrated moderate overall alignment with clinical manifestations， mainly reflecting disease characteristics. However， they generally lack representation of TCM syndrome features. ConclusionExisting RVO models are predominantly based on Western medicine and lack TCM syndrome features. Western medical treatments for RVO have certain limitations， while syndrome differentiation and treatment in TCM offer potential advantages. Future research should focus on developing disease-syndrome integrated animal models that incorporate both pathological features and TCM syndrome characteristics. This approach will enhance the design of RVO models and facilitate both basic and clinical research， which make it a scientifically valuable and necessary endeavor.

AIM:To compare the effect of AT TORBI 709M and Tecnis ZMT intraocular lenses on astigmatism correction in patients with corneal astigmatism at 3 mo after operation based on the standard astigmatism vector analysis.METHODS: This was a retrospective case-control study. The clinical data of 69 patients(69 eyes)with corneal astigmatism who underwent phacoemulsification and implantation of toric intraocular lens(IOL)from June 2021 to December 2021 in Day Surgery Center of Xi'an No.1 Hospital was analyzed. The patients were divided into two groups. In group one, 38 cases(38 eyes)were implanted with AT TORBI 709M, and 31 patients(31 eyes)with Tecnis ZMT in group two. The axial length, preoperative astigmatism and axis, and the degree of intraocular lens were recorded. The uncorrected distance visual acuity(UCDVA), best corrected distance visual acuity(BCDVA), diopter, residual astigmatism and axis were recorded preoperatively and at 1 wk, 1 and 3 mo postoperatively. The postoperative surgical indicators, including spherical equivalent(SE), target induced astigmatism vector(TIA), surgically induced astigmatism vector(SIA), magnitude of error(ME), absolute value of angle of error(|AE|), absolute value of difference vector(|DV|), correction index(CI), and index of success(IOS)were evaluated by the standard astigmatism vector analysis.RESULTS:Postoperative UCDVA and BCDVA were significantly improved(all P<0.001), and there were statistically significant differences compared to preoperative UCDVA and BCDVA(all P<0.001). While, there was no significant difference in UCDVA and BCDVA between the two groups(P=0.275, 0.124). The standard astigmatism vector analysis showed that a good astigmatism correction was achieved in both AT TORBI 709M group and Tecnis ZMT group, and both |DV| and IOS were close to 0(P=0.329, 0.288). The CI of the AT TORBI 709M group was closer to 1, indicating a better astigmatism correction, while the CI of the Tecnis ZMT group was higher than 1, suggesting an overcorrection of astigmatism. However, the difference between the two groups was not statistically significant(P=0.193). The mean residual astigmatism at 3 mo postoperatively was -0.11±0.91 D in the AT TORBI 709M group and -0.46±0.76 D in the Tecnis ZMT group, respectively, showing no statistically significance difference(t=1.732, P=0.088).CONCLUSION:Both the flat loop AT TORBI 709M and the double C-loop Tecnis ZMT intraocular lenses can effectively improve postoperative visual acuity in patients with regular corneal astigmatism, showing good rotational stability and comparable correction abilities for both astigmatism with the rule and against-the-rule astigmatism.

Metabolic reprogramming plays a central role in tumors. However, the key drivers modulating reprogramming of gluconeogenesis/lipogenesis are poorly understood. Here, we try to identify the mechanism by which histone acetyltransferase 1 (HAT1) confers reprogramming of gluconeogenesis/lipogenesis in liver cancer. Diethylnitrosamine (DEN)/carbon tetrachloride (CCl₄)-induced hepatocarcinogenesis was hardly observed in HAT1-knockout mice. Multi-omics identified that HAT1 modulated gluconeogenesis and lipogenesis in liver. Protein phosphatase 2 scaffold subunit alpha (PPP2R1A) promoted gluconeogenesis and inhibited lipogenesis by phosphoenolpyruvate carboxykinase 1 (PCK1) serine 90 dephosphorylation to suppress the tumor growth. HAT1 succinylated PPP2R1A at lysine 541 (K541) to block the assembly of protein phosphatase 2A (PP2A) holoenzyme and interaction with PCK1, resulting in the depression of dephosphorylation of PCK1. HAT1-succinylated PPP2R1A contributed to the remodeling of gluconeogenesis/lipogenesis by PCK1 serine 90 phosphorylation, leading to the inhibition of gluconeogenic enzyme activity and activating sterol regulatory element-binding protein 1 (SREBP1) nuclear accumulation-induced lipogenesis gene expression, which enhanced the tumor growth. In conclusion, succinylation of PPP2R1A lysine 541 by HAT1 converses the role in modulation of gluconeogenesis/lipogenesis remodeling through PCK1 S90 phosphorylation to support liver cancer. Our finding provides new insights into the mechanism by which post-translational modifications (PTMs) confer the conversion of tumor suppressor function to oncogene.

OBJECTIVES: To investigate the active ingredients in Hedyotis diffusa-Scutellaria barbata D. Don and the main biological processes and signaling pathways mediating their inhibitory effect on primary hepatocellular carcinoma (HCC). METHODS: The core intersecting genes of HCC and the two drugs were screened from TCMSP, Uniport, Genecards, and String databases using Cytoscape software, and GO and KEGG enrichment analyses of the intersecting genes were conducted. Molecular docking between the active ingredients of the drugs and the core genes was carried out using Pubcham, RCSB and Autoduckto to identify the active ingredients with the highest binding energy, whose inhibitory effect on HepG2 cells was verifies using CCK-8 assay, flow cytometry and Western blotting. RESULTS: TP53 and ESR1 were identified as the core genes of HCC and the two drugs. GO and KEGG analyses showed that the two genes were mainly involved in regulation of apoptotic signaling pathway, cell population proliferation, methane raft, and protein kinase activity, and participated in the signaling pathways of apoptosis, proteoglycans in cancer, PI3K Akt signaling pathway, and hepatitis B. Molecular docking studies showed that the active ingredients of the drugs could be docked with TP53 and ESR1 genes under natural conditions, and ursolic acid had the highest binding energy to ESR1 (-4.98 kcal/mol). The results of CCK-8 assay, flow cytometry and Western blotting all demonstrated significant inhibitory effect of ursolic acid on HepG2 cells. CONCLUSIONS The inhibitory effect of Hedyotis diffusa-scutellariae barbatae on HCC is mediated by multiple active ingredients in the two drugs.

Objective:To observe the clinical effect of lower eyelid blepharoplasty combined with micro-autologous fat transplantation (MAFT) in the rejuvenation of the infraorbital regions.Method:A retrospective analysis was conducted on the clinical data of patients with lower eyelid pouch and tear trough treated with lower eyelid blepharoplasty combined with MAFT in the Department of Plastic Surgery of Affiliated Hospital of Nanjing University of Chinese Medicine from March 2020 to March 2022. Patients seeked medical attention due to lower eyelid pouch and tear trough, with or without skin laxity, and some patients had varying degrees of midface depression. After preoperative examination and evaluation of the patient’s infraorbital area and midfacial depression, appropriate individualized plans were developed.The patient underwent lower eyelid blepharoplasty by transconjunctival approach combined with tear trough MAFT. For patients with low or depressed midface, midface MAFT was also performed, and for patients with skin laxity, skin removal surgery was performed simultaneously. Complications were recorded after the operation. Preoperative and postoperative photos of more than 6 months were taken with the same postion and delivered to the same doctor to grade the patient’s Barton classification (0-3 grades, with higher grade indicating more obvious tear trough deformity). The improvement of tear trough deformity after surgery was assessed, and the global aesthetic improvement scale (GAIS) score was also assessed. The patients evaluated their improvement using the patients aesthetic improvement scale (PAIS) score (GAIS and PAIS are both 1-5 points, with higher scores indicating more significant postoperative improvement). Normal distribution metric data was represented by Mean±SD, and count data was represented by frequency and/or percentage; skewed distribution metric data was represented by M ( Q1, Q3), and compared by rank sum test. Results:A total of 69 patients were enrolled, including 9 males and 60 females, aged 25-45 years, with an average age of 36.7 years. Among them, 35 patients had midfacial depression, and 11 patients had skin laxity. (0.37±0.07) ml (0.2-0.6 ml) of micro-autologous fat was injected into the orbicularis oculi muscle on each side; (0.18±0.06) ml (0.1-0.2 ml) of micro-autologous fat was injected into the subcutaneous layer on each side; (3.80±0.98) ml (3-5 ml) of micro-autologous fat was injected into the deep medial cheek fat compartment and pyriform aperture fat compartment on each side. No serious complications occurred after the surgery. Postoperative follow-up lasted for 6-13 months, with an average of 8.7 months. The patient’s lower eyelid pouch, tear trough deformity, and depression in the midface have all improved, presenting a youthful and smooth appearance from the infraorbital area to the midface. The skin texture in the lower eyelid area had also improved. At the last follow-up, the Barton classification of the lacrimal groove decreased compared with that before surgery, and the difference was statistically significant [grade 0 (0, 1) vs. grade 2 (1, 2), Z=-7.62, P<0.001]. At the last follow-up, the PAIS score of 69 patients was 5 points in 49 cases (71%) and 4 points in 20 cases (29%); doctor’s GAIS score was 5 points in 38 cases (55%), 4 points in 27 cases (39%), and 3 points in 4 cases (6%) . Conclusion:For those patients with aging status of infraorbital region, like lower eyelid pouch and tear trough deformities, the combination of lower eyelid blepharoplasty through the transconjunctival approach and MAFT can achieve good therapeutic effects. This method is safe with a short recovery time.

Objective The purpose of this study was to explore a suitable method to model no-reflow phenomenon following ischemic stroke and to evaluate perfusion decrease from multiple perspectives.Methods Laser scatter contrast imaging and two-photon live imaging were used to compare transient middle cerebral artery occlusion in C57BL/6 and BALB/c mice and perfusion alterations in BALB/c mice with 1 or 1.5 h of ischemia.Several imaging techniques including laser scatter contrast imaging,low and higher magnification images of perfused brain slices and two-photon microscopy to monitor erythrocyte flow rate and flux were used to assess in vivo dynamics as well as whole brain sections and microvasculature for decreased cerebral perfusion after transient middle cerebral artery occlusion.Infarct size and behavioral deficits were assessed with microtubule-associated protein 2 staining and behavioral scoring.Results In C57BL/6 mice,most capillaries in the middle cerebral artery region remained flowing during ischemia,whereas most capillaries were blocked in BALB/c mice.In addition,cortical perfusion at 24 h of recanalization was significantly reduced to 76.1%of baseline following 1.5 h of ischemia in BALB/c mice(P=0.046 compared with the sham group),whereas for it was reduced to 79.9%following 1h of ischemia which was not significantly different from the sham group(P=0.299).Transient middle cerebral artery occlusion in BALB/c mice for 1.5 h resulted in a reduction in whole-brain perfusion to 75.1%(P＜0.001 compared with the sham group),and erythrocyte flow rate assessed by two-photon live-imaging of erythrocyte flow on the cortical surface of the middle cerebral artery basin was reduced to 50.3%of baseline levels at 24 h of recanalization(P=0.010 compared with the sham group),and erythrocyte flux decreased to 38.9%of baseline levels(P= 0.010 compared with the sham group);high-magnification imaging of sections assessed an approximately 76%reduction in the length of capillaries with perfusion(P=0.0001 compared with the sham group),and a reduction in the fraction of the total volume occupied by perfused capillaries by an approximately 76%reduction(P＜0.001 compared with the sham-operated group).Microtubule-associated protein 2 staining suggested that transient middle cerebral artery occlusion for 1.5 h in BALB/c mice resulted in infarcts that accounted for approximately 36%of the total cerebral area and behavioral scores elevated to 9,suggesting behavioral deficits.Conclusion Transient ischemia in BALB/c mice for 1.5 h resulted in a significant decrease in cerebral perfusion as well as capillary no-reflow and thus can model the no-reflow phenomenon following ischemic stroke.The combination of laser scatter contrast imaging,low magnification and higher magnification images of perfused brain slices,and two-photon microscopy live imaging allows for a multifaceted assessment of perfusion changes.

Methamphetamine(METH)is highly addictive and neurotoxic,which causes cognitive and memory dysfunction in abusers.The harm of METH lies not only in its own toxicity,but also in the high physical and mental dependence of drug addicts,often causing mental disorders and violent behavior,bringing great safety risks to society.Non-coding RNA(ncRNA)does not encode proteins and is an important factor in regulating gene expression at the post-transcriptional level.Studies have shown that ncRNA plays an important regulatory role in methamphetamine-induced addiction and neurotoxicity,but the specific mechanism is unclear.This article reviews the current research progress of ncRNA in regulating METH-induced addiction and neurotoxicity to provide a reference for ncRNA as a forensic identification index and potential therapeutic target for METH abusers.

Objective:To explore the current situation and influencing factors of quality of life of septic patients in intensive care unit (ICU) after discharge, and to provide theoretical basis for clinical early psychological intervention and continuity of care.Methods:A prospective observational study was conducted. The septic patients who were hospitalized in the department of critical care medicine of the Affiliated Hospital of Jining Medical University and discharged with improvement from January 1 to December 31, 2022 were selected as the research objects. The demographic information, basic diseases, infection site, vital signs at ICU admission, severity scores of the condition within 24 hours after ICU admission, various biochemical indexes, treatment process, and prognostic indexes of all the patients were recorded. All patients were assessed by questionnaire at 3 months of discharge using the 36-item short-form health survey scale (SF-36 scale), the activities of daily living scale (ADL scale), and the Montreal cognitive assessment scale (MoCA scale). Multiple linear regression was used to analyze the factors influencing the quality of life of septic patients after discharge from the hospital.Results:A total of 200 septic patients were discharged with improvement and followed up at 3 months of discharge, of which 150 completed the questionnaire. Of the 150 patients, 57 had sepsis and 93 had septic shock. The total SF-36 scale score of septic patients at 3 months of discharge was 81.4±23.0, and the scores of dimensions were, in descending order, role-emotional (83.4±23.0), mental health (82.9±23.6), bodily pain (82.8±23.3), vitality (81.6±23.2), physical function (81.4±23.5), general health (81.1±23.3), role-physical (79.5±27.0), and social function (78.8±25.2). There was no statistically significant difference in the total SF-36 scale score between the patients with sepsis and septic shock (82.6±22.0 vs. 80.7±23.6, P > 0.05). Incorporating the statistically significant indicators from linear univariate analysis into multiple linear regression analysis, and the results showed that the factors influencing the quality of life of septic patients at 3 months after discharge included ADL scale score at 3 months after discharge [ β= 0.741, 95% confidence interval (95% CI) was 0.606 to 0.791, P < 0.001], length of ICU stay ( β= -0.209, 95% CI was -0.733 to -0.208, P = 0.001), duration of mechanical ventilation ( β= 0.147, 95% CI was 0.122 to 0.978, P = 0.012), total dosage of norepinephrine ( β= -0.111, 95% CI was -0.044 to -0.002, P = 0.028), mean arterial pressure (MAP) at ICU admission ( β= -0.102, 95% CI was -0.203 to -0.007, P = 0.036) and body weight ( β= 0.097, 95% CI was 0.005 to 0.345, P = 0.044). Conclusions:The quality of life of patients with sepsis at 3 months after discharge is at a moderately high level. The influencing factors of the quality of life of patients with sepsis at 3 months after discharge include the ADL scale score at 3 months after discharge, the length of ICU stay, the duration of mechanical ventilation, the total dosage of norepinephrine, MAP at ICU admission and body weight, and healthcare professionals should enhance the treatment and care of the patients during their hospitalization based on the above influencing factors, and pay attention to early psychological intervention and continued care for such patients.
