OBJECTIVE To establish a clinical comprehensive evaluation framework for direct oral anticoagulants （DOACs） in the prevention of cancer-associated venous thromboembolism （CAVTE）， providing a methodological reference for the rational prevention and treatment of CAVTE as well as for the formulation and adjustment of macro-management strategies for anticoagulant drugs. METHODS Through literature retrieval， evaluation indicators were collected and organized to establish a preliminary indicator pool. The selection of evaluation indicators was carried out through two rounds of Delphi surveys using average score of indicator importance≥3.5 and a coefficient of variation （CV） ＜0.25 as the screening criteria. Analytic hierarchy process （AHP） was employed to finalize the indicator weights. RESULTS The authority levels （C）r of the two rounds of expert consultations were 0.877 and 0.943， with CV of 0.24 and 0.18， respectively. The Kendall concordance coefficients were 0.331 and 0.535 （P＜0.05）. After expert validation， six primary indicators and forty-six secondary indicators were finalized for inclusion in the evaluation framework. The primary indicators and their weightings， ranked in descending order， were as follows：“ effectiveness” （38.86%）， “safety” （38.86%），“ cost-effectiveness” （10.67%），“ accessibility” （5.51%），“ suitability” （3.48%）， and “innovation” （2.64%）. The secondary indicators exhibited a weight range from 0.02% to 20.25%， with the top five secondary indicators being：“ incidence of intracranial hemorrhage” （20.25%）， “reduction in all-cause mortality” （15.29%）， “decrease in the incidence of pulmonary embolism” （8.82%）， “reduction in the incidence of deep vein thrombosis” （7.25%）， and “drug contraindications” （4.74%）. CONCLUSIONS This study has established an authoritative， scientific， and reliable comprehensive clinical evaluation framework for the use of DOACs in the prevention of CAVTE.

Keratoconus is a blinding corneal disease that is particularly prevalent among adolescents. Early diagnosis and treatment can significantly reduce visual impairment in advanced stages and improve its prognosis. Based on machine learning and deep learning in keratoconus, Artificial intelligence(AI)mainly involves early screening and diagnosis, severity grading, progression prediction, and outcomes prediction. In this paper, the main applications and research progress of AI in keratoconus in recent years were summarized, and the challenges and future prospects in this field were discussed.

AIM: To investigate the relationship between objective ocular torsion and near stereopsis in patients with primary superior oblique overaction(PSOOA).METHODS: Retrospective study. A total of 59 strabismus patients with PSOOA who underwent strabismus surgery at Renmin Hospital of Wuhan University between January 2019 and November 2023 were collected. Based on the collected fundus photographs and the position of the fovea relative to the horizontal line through the optic disc, the eyes were categorized as incyclotorsion, excyclotorsion, or no cyclotorsion. Additionally, the fovea-disc angle(FDA)and the relationship between objective ocular torsion status, FDA, and near stereopsis function in the patients were further measured and analyzed.RESULTS: Totally 59 patients(92 eyes)showed superior oblique overaction. There were no cases of excyclotorsion, 32 cases with no cyclotorsion, and 27 cases with incyclotorsion. The total binocular FDA was significantly smaller in the no-cyclotorsion group compared with the incyclotorsion group(2.83°±2.89° vs 16.12°±5.74°, P<0.001). The preservation rates of near stereopsis were 66% and 15% in the no-cyclotorsion and incyclotorsion groups, respectively, with a significant statistical difference(P<0.001), and the preservation rates of fine near stereopsis were 38% and 11% in the no-cyclotorsion and incyclotorsion groups, respectively, with a significant statistical difference(P=0.02). Among all patients, near stereopsis was correlated with total binocular FDA(r=-0.526, P<0.001), with the strongest correlation observed with the FDA of the incyclotorsion(r=-0.546, P<0.001). In the incyclotorsion group, there was no correlation between near stereopsis and total binocular FDA(r=-0.366, P=0.060), with a negative correlation between near stereopsis and the FDA of both the incyclotorsion and the overaction(r=-0.424, P=0.028; r=-0.485, P=0.010). In the no-cyclotorsion group, near stereopsis was not correlated with total binocular FDA, incyclotorsion FDA, or overaction FDA.CONCLUSION:PSOOA patients with incyclotorsion have a lower preservation rate of near stereopsis than those without cyclotorsion. Near stereopsis function of patients with PSOOA is negatively correlated with total binocular FDA, especially the greater the FDA of the incyclotorsion and overaction, the worse the near-stereoscopic function.

ObjectiveThis study aimed to evaluate the clinical efficacy of Ruyi Zhenbaowan（RYZBW）in the treatment of initial and early knee osteoarthritis （KOA） through a prospective multicenter，randomized，double-blind，and placebo-parallel controlled trial. MethodFrom October 13^th， 2021 to December 25^th， 2021， 240 KOA subjects meeting the acceptance criteria were enrolled in 15 sub-centers including Wangjing Hospital， Chinese Academy of Chinese Medical Sciences， and they were randomly divided into observation group and control group， with 120 cases in each group. The intervention measures for the observation group were RYZBW + health education， and the intervention measures for the control group were RYZBW placebo + health education. The intervention period in both groups was four weeks， and they were followed up for four weeks after the intervention. The primary outcome measure was the total score of Western Ontario and McMaster University Osteoarthritis Index score （WOMAC score）， and the secondary outcome measures were the response rate of visual scale （VAS） pain score， WOMAC sub item scores （joint pain， joint stiffness， and joint function）， quality of life （SF-12） score， and traditional Chinese medicine （TCM） syndrome score. Result（1） Efficacy evaluation. The marginal model results showed that the observation group was better than the control group in improving the WOMAC total score and WOMAC pain score in the treatment of KOA with RYZBW， and the difference was statistically significant （P<0.05）. There was no significant difference between the two groups in improving VAS score response rate， WOMAC function score， WOMAC stiffness score， SF12-PCS （quality of life-physical health） score， SF12-MCS （quality of life-mental health） score， and TCM syndrome score. （2） Subgroup analysis. ① In terms of VAS score response rate， the response rate of the observation group was higher than that of the control group for subjects with baseline VAS score of （4， 5］， and the difference was statistically significant （P<0.05）. ② In terms of TCM syndrome score， for subjects aged ［56， 60］ and ［61， 65］， the decrease in total TCM syndrome score in the observation group was better than that in the control group， and the difference was statistically significant （P<0.05）. ConclusionTibetan medicine RYZBW has good clinical efficacy in improving WOMAC total score， VAS score response rate， WOMAC pain score， WOMAC function score， and TCM syndrome score for patients with initial and early KOA， which can fill the lack of Tibetan medicine RYZBW in the treatment of KOA and make a demonstration study for the inheritance and development of ethnic medicine.

Oxalate is an organic dicarboxylic acid that is a common component of plant foods.The kidneys are essential organs for oxalate excretion,but excessive oxalates may induce kidney stones.Jupiter micro-tubule associated homolog 2(JPT2)is a critical molecule in Ca2+mobilization,and its intrinsic mecha-nism in oxalate exposure and kidney stones remains unclear.This study aimed to reveal the mechanism of JPT2 in oxalate exposure and kidney stones.Genetic approaches were used to control JPT2 expression in cells and mice,and theJPT2 mechanism of action was analyzed using transcriptomics and untargeted metabolomics.The results showed that oxalate exposure triggered the upregulation of JPT2,which is involved in nicotinic acid adenine dinucleotide phosphate(NAADP)-mediated Ca2+mobilization.Tran-scriptomic analysis revealed that cell adhesion and macrophage inflammatory polarization were inhibited by JPT2 knockdown,and these were dominated by phosphatidylinositol 3-kinase(PI3K)/AKT signaling,respectively.Untargeted metabolomics indicated that JPT2 knockdown inhibited the produc-tion of succinic acid semialdehyde(SSA)in macrophages.Furthermore,JPT2 deficiency in mice inhibited kidney stones mineralization.In conclusion,this study demonstrates that oxalate exposure facilitates kidney stones by promoting crystal-cell adhesion,and modulating macrophage metabolism and in-flammatory polarization via JPT2/PI3K/AKT signaling.

Objective:To compare the efficacy and safety of endoscopic cold snare polypectomy(CSP)and hot snare polypectomy(HSP)on 5 to 10 mm colonic polyps in children.Methods:One hundred and eighteen children, who underwent colonoscopy at Children′s Hospital Affiliated to Jiangnan University from June 2018 to June 2022 and found polyps with a diameter of 5-10 mm, were selected as the study subjects.They were divided into two groups by random number table method, with CSP(CSP group) and HSP(HSP group) for polypectomy respectively.The time required to remove a single polyp, intraoperative bleeding rate, postoperative bleeding rate, abdominal discomfort rate, hospitalization time, and hospitalization costs were compared between two groups.Results:Among 118 cases, there were 58 cases in CSP group, including 36 males and 22 females, with an average age of (6.17±3.34) years.There were 60 cases in HSP group, including 34 males and 26 females, with an average age of (5.68±3.18) years.There were no significant differences in sex and age between two groups( P>0.05). Compared with HSP group, the time required to remove a single polyp in CSP group was shorter[(6.68±0.34)min vs.(7.60±0.53)min], the rate of delayed postoperative bleeding was lower (0 vs.10.0%), the hospitalization time was shorter[(5.50±1.87) d vs.(6.38±1.38) d], and the hospitalization expenses were lower[(7 646.99±3 575.10)yuan vs.(10 006.47±3 657.42)yuan]. The differences were statistically significant (all P<0.05). Conclusion:The application of CSP to remove 5-10 mm colon polyps in children could shorten surgical treatment time and reduce the occurrence of complications.At the same time, it could reduce the hospitalization time and cost, and the overall effect is positive and safe, which is worthy of popularization and application by pediatricians in clinical practice.

Myopia is the most common type of refractive error. At present, the characteristics of the low age and rapid growth of myopia in our country are obvious, and the myopia of adolescents and children has become a public health problem of concern to the whole society. Visual experience guides the development of children's refractive state and emmetropization. The occurrence and development of myopia is accompanied by changes in the structure of the eyeball, and the choroid has a thinning trend. The thickness change of the choroid may be determined by blood flow perfusion. Decreased choroidal blood flow perfusion may lead to scleral ischemia and hypoxia, and hypoxia induces scleral matrix remodeling and axial length growth. This article reviews the relationship between choroidal blood flow and myopia, and suggests the significance of paying attention to choroidal changes in the prevention and control of myopia.

Acute kidney injury (AKI) is an important factor for the occurrence and development of CKD. The protective effect of dihydroartemisinin on AKI and and reported mechanism have not been reported. In this study, we used two animal models including ischemia-reperfusion and UUO, as well as a high-glucose-stimulated HK-2 cell model, to evaluate the protective effect of dihydroartemisinin on premature senescence of renal tubular epithelial cells in vitro and in vivo. We demonstrated that dihydroartemisinin improved renal aging and renal injury by activating autophagy. In addition, we found that co-treatment with chloroquine, an autophagy inhibitor, abolished the anti-renal aging effect of dihydroartemisinin in vitro. These findings suggested that activation of autophagy/elimination of senescent cell might be a useful strategy to prevent AKI/UUO induced renal tubular senescence and fibrosis.

Autologous ozonized blood transfusion(AOBT) is a therapy of re-transfusion of 100-200 mL of autologous blood after shaking and agitation with appropriate amount of oxygen-ozone in vitro. The oxidation of blood through the strong oxidation of ozone can enhance the non-specific immune response of the body, regulate the internal environment and promote health. This therapy has been increasingly applied in clinical practice, while no unified standard for the operation process in terms of ozone concentration, treatment frequency and treatment course had been established. This operation process of AOBT is primarily explored in order to standardize the operation process and ensure its safety and efficacy.

【Objective】 To investigate whether diosmetin has protective effects on renal ischemia-reperfusion (I/R) injury in mice and explore the potential mechanism. 【Methods】 A total of 45 BALB/c male mice were randomly divided into the sham group, I/R group and diosmetin treatment group. The protective effects of diosmetin on the renal function of mice was evaluated by detecting blood biochemical indexes and renal tissue HE staining injury score. The expression of p-P65, a key molecule of NF-κB family, was detected with immunohistochemistry and western blotting, and the downstream inflammatory factors of NF-κB signaling pathway were detected with quantitative polymerace chain reaction (qPCR). 【Results】 Compared with the sham group, the I/R group had significantly increased levels of serum creatinine and urea nitrogen, significantly damaged morphological construction, and significantly increased expressions of p-P65 and inflammatory cytokines, while the diosmetin treatment group had decreased levels of serological indexes, improved structure of kidney tissue and reduced expressions of p-P65 and inflammatory cytokines. 【Conclusion】 Diosmetin can protect kidney from I/R-induced acute kidney injury by inhibiting NF-κB pathway in mice.
