ObjectiveThis study aimed to explore the correlation between the quality of life （QOL） and different traditional Chinese medicine （TCM） syndromes in patients with myasthenia gravis （MG）， identifying potential influencing factors to provide new insights for clinical interventions and improving the QOL of patients with MG. MethodsA questionnaire survey was conducted on 93 adults with MG who visited the Department of Neurology at the Affiliated Hospital of Changchun University of Chinese Medicine from March 2023 to January 2024. Statistical analysis was performed on the clinical data collected using SPSS 24.0 software. ResultsAmong the 93 patients with MG， the average score for myasthenia gravis quality of life-15 （MGQOL-15） was 17.65±6.27， and that for the 36-item short form health survey （SF-36） was （106.13±11.83） scores. The QOL was rated as good for 16 patients and moderate for 77 patients. There were no statistically significant differences in the scores of MGQOL-15， SF-36， and their individual scales by gender or education level. Age showed statistically significant differences in MGQOL-15 and the role physical （RP） scale （P<0.05）， and occupational type showed significant differences in the vitality （VT） scale （P<0.01）. The Myasthenia Gravis Foundation of America （MGFA） classification had statistical significance on the total SF-36 score （P<0.01）， VT scale （P<0.01）， role emotional （RE） scale （P<0.05）， social functioning （SF） scale （P<0.05）， and physical functioning （PF） scale （P<0.01）. Among patients with different TCM syndromes， there were significant differences in MGQOL-15 scores （F=4.919， P<0.01）. Moreover， significant differences were observed in SF-36 scores （P<0.01）， VT scale （P<0.01）， RE scale （P<0.05）， mental health （MH） scale （P<0.01）， and SF scale （P<0.05）. ConclusionFactors affecting the QOL of patients with MG include age， occupational type， and clinical classification of MG. Specifically， a greater impact on the QOL of older patients is observed， while physical laborers have a poorer QOL compared to non-physical laborers. Patients classified as MGFA type Ⅱ and higher have a poorer QOL. Additionally， there is a potential correlation between the QOL and TCM syndromes， with patients presenting with spleen and kidney Qi deficiency having a lower QOL than those with spleen and stomach Qi deficiency or Qi and Yin deficiency， which is particularly evident in the VT， RE， MH， and SF scales.

Ischemia-reperfusion (I/R) injury following skin flap transplantation is a critical factor leading to flap necrosis and transplant failure. Antagonizing inflammatory responses and oxidative stress are regarded as crucial targets for mitigating reperfusion injury and enhancing flap survival. In this study, caffeic acid-vanadium metal polyphenol nanoparticles (CA-V NPs) were prepared for the treatment of skin flap ischemia and reperfusion. This study was conducted using a one-step method to prepare new types of CA-V NPs with uniform sizes and stable structures. In vitro, the CA-V NPs exhibited CAT-like and SOD-like activities and could effectively scavenge ROS, generate oxygen, and alleviate oxidative stress. In the H₂O₂-induced cellular oxidative stress model, CA-V NPs effectively reduced ROS levels and inhibited apoptosis through the XIAP/Caspase-3 pathway. In the cellular inflammation model induced by LPS combined with IFN-γ, CA-V NPs reprogrammed macrophage polarization toward the M2 phenotype and reduced inflammatory responses by reducing the expression of the chemokines CCL4 and CXCL2. In addition, animal experiments have shown that CA-V NPs can alleviate oxidative stress in skin flap tissues, inhibit apoptosis, promote angiogenesis, and ultimately improve the survival rate of skin flaps. CA-V NPs provide a new target and strategy for the treatment of flap I/R injury.

OBJECTIVES: This study aims to evaluate the changes in the mandibular canal following the treatment of large odontogenic keratocysts through decompression and curettage, providing a theoretical basis for sequential treatment. METHODS: Twenty patients were selected for each decompression and curettage treatment of large odontogenic keratocysts in the mandible. Postoperative follow-up with was conducted every three months, during which cone beam computed tomography (CBCT) scans were performed. Then, the data were imported into MIMICS software to observe 3D changes in the position and structure of the mandibular nerve canal, followed by a comparative analysis. RESULTS: The total displacement of the mandibular canal was (1.89±0.21) mm on the decompression side and (0.80±0.19) mm on the curettage side. Vertically, the displacement range of the mandibular canal on the decompression side (M=1.03, SD=0.17) was larger than on the curettage side (M=0.52, SD=0.010) within nine months post-operation. In the buccal-lingual direction, the ratio of the thickness of the buccal plate to the lingual plate gradually increased with time. The amount of bone reconstruction at the part of the mandibular nerve canal closest to the cyst was (1.75±0.15) mm on the decompression side and (1.45±0.09) mm on the curettage side after nine months. CONCLUSIONS The mandibular nerve canal showed varying degrees of recovery and "relocation" after two surgical procedures. Osteogenesis around the mandibular nerve canal was more remarkable after decompression than after curettage. Therefore, for large odontogenic keratocyst, decompression is recommended as the initial treatment, followed by secondary curettage nine months later.

Digital biopsy for liver diseases is characterized by the deep integration of artificial intelligence （AI） technologies and large-scale liver disease data， through which intelligent analytics are applied to support clinical decision-making and full-cycle management. This article reviews the AI technical framework based on standardized data governance and centered on multimodal large medical models， covering the application of natural language processing， knowledge map， generative AI， and large language models in the establishment of databases for specialty diseases， diagnosis， prognosis prediction， treatment， and automated medical documentation. This article also discusses the application prospects of this framework in medical education， scientific research， and healthcare management. Although this technique shows broad application potential， it still faces challenges in areas such as multi-center data integration， model interpretability， ethics， and data security. In the future， a smart ecosystem with closed-loop optimization and human-AI collaboration should be established to promote the comprehensive implementation of digital biopsy in the whole process of medicine， education， research， and management， thereby providing help for the precise prevention and control and holistic health management of liver diseases.

AIM:To observe the anti-scarring effects and safety of triamcinolone acetonide(TA)-loaded hydrogel sustained-release sheeting on stab incision glaucoma surgery(SIGS)with “one-step tunnel method” in rabbit eyes.METHODS:A total of 48 healthy New Zealand white rabbits were randomly selected and divided into 4 groups(12 rabbits in each group), trabeculectomy(Trab)group, SIGS group, polyvinyl alcohol hydrogel(PVAH)sheeting was implanted under the conjunctiva flap during SIGS(PVAH group), and hydrogel sustained-release sheeting loaded with TA was implanted under the conjunctiva flap during SIGS(TA/PVAH group). On the 1, 2, 3, and 4 wk after surgery, the intraocular pressure, filtering bubble morphology, anterior chamber reaction, and other complications were observed and recorded in each group. Then animals were euthanized, and the surgery area tissues of right eye were taken for pathological tissue paraffin section. Masson staining, picric acid-Sirius rose red staining, as well as α-smooth muscle actin(α-SMA)and fibroblast growth factor 2(FGF2)immunohistochemistry staining was performed on every section. The infiltration of inflammatory cells, proliferation of fibroblasts and synthesis of type I and type III collagen fibers in local tissues were observed. The average positive area ratio of α-SMA and FGF2 antibody immunohistochemical staining in each group was calculated and compared.RESULTS: The TA/PVAH group maintained diffuse and elevated functional filtering blebs, while flat filtering blebs appeared in Trab, SIGS and PVAH groups at 2 wk after surgery. Functional filtering blebs were present in 1 eye(33%), 2 eyes(67%)in the PVAH and TA/PVAH group at 4 wk after surgery, respectively, while the other filtering blebs were flattened. Masson staining showed that the hydrogels in PVAH and TA/PVAH groups did not degrade at 4 wk after surgery. Compared with the Trab and SIGS groups, the filtration passages were more obvious, with less collagen fiber proliferation. Sirius red staining showed that the expression of type I collagen and type III collagen in the TA/PVAH group was less than that in the Trab group, SIGS group and PVAH group at 4 wk after surgery. Immunohistochemical staining showed that the α-SMA expression in the TA/PVAH group was significantly lower than that in the Trab and SIGS groups at 1 wk after surgery(P<0.01). The α-SMA expression was the highest in the Trab and SIGS groups at 2 wk after surgery, while the α-SMA expression in the PHAP and TA/PVAH groups was significantly lower than that in the first two groups(P<0.01). Compared with the Trab group, the expression of FGF2 in the PVAH and TA/PVAH group was significantly increased at 1, 2, 3 and 4 wk after surgery(P<0.05). Compared with the SIGS group, FGF2 expression in the TA/PVAH group was significantly increased at 4 wk after surgery(P<0.05).CONCLUSION:In SIGS surgery of rabbit eyes, implanting hydrogel sustained-release sheeting loaded with TA under conjunctival flap can effectively inhibit the scarring of the filtering bleb, which may be the interaction of the anti-scar effect of TA and the stent function of hydrogel.

(6.64±2.02), (6.00±1.50) vs . (6.78± 2.14)], the total score of doctors [(5.92±1.37) vs . (6.64±2.15), (5.92±1.47) vs . (6.68±1.98)] and the total score [(5.92±1.42) vs. (6.66±2.05)] were lower than the first evaluation score ( P<0.05). The second scores of depression for female doctors [(6.15±1.37) vs . (6.68±2.06)], doctors in medical laboratory department [(6.02±1.40) vs . (6.69±1.88)], doctors from tertiary hospital [(6.13±1.41) vs. (6.51±1.90)], doctor with different training durations [(6.04±1.42) vs . (6.50±2.02), (6.12±1.34) vs . (6.57±1.97)] and the total score of doctors [(6.09±1.37) vs . (6.54±1.99)] were lower than those of the first evaluation ( P < 0.05). The anxiety score of the second evaluation in the control group was higher in male physicians [(6.63±1.15) vs . (6.11±1.76)] than the first evaluation ( P < 0.05). Compared with the second evaluation data of doctors in the two groups, in terms of anxiety scores, the scores of doctors at all levels and total scores in the intervention group were lower than those in the control group ( P < 0.05); in terms of depression score, the scores of female visiting doctors, doctors from tertiary hospitals, doctors with refresher training duration of 6 months and total score were lower than those of the control group ( P < 0.05). Conclusion:The application of humanistic management to strengthen the management of refresher physicians can improve the psychological state of refresher doctors to a certain extent, especially alleviate the anxiety state, which is a worthy promotion of refresher management mode.

Objective:To investigate the risk factors of high intraocular pressure (IOP) after femtosecond laser in situ keratomileusis (FS-LASIK) in patients with high myopia, and construct and verify nomogram model.Methods:A retrospective clinical study. From January 2019 to January 2021, 327 patients (654 eyes) with high myopia treated with FS-LASIK in the Department of Ophthalmology of the 910th Hospital of the People's Liberation Army Coalition Security Force were included in the study. The patients were categorized into high IOP group and non-high IOP group according to whether high IOP occurred after surgery, which were 60 cases and 120 eyes (18.35%, 60/327) and 267 cases and 534 eyes (81.65%, 267/327), respectively. The clinical data of patients in the two groups were analyzed and observed, and the indicators with differences were subjected to one-way and multifactorial logistic regression analyses, and the results of the regression analyses were visualized to obtain the column line graphs using R3.5.3 software, and the accuracy of the column line graphs was verified by the consistency index (C-index), the calibration curves, and the subject's work characteristic curves (ROC curves).Results:Comparison of the number of cases of affected corneal thickness ( χ2=7.424), corneal curvature ( χ2=9.849), glucocorticoid treatment ( χ2=7.222), intraoperative IOP fluctuation ( χ2=11.475), corneal hysteresis ( χ2=6.368), and the incidence of intraoperative complications ( χ2=6.673) in the hypertensive IOP group and the nonvisualized IOP group were statistically significant ( P<0.05). Binary logistic regression analysis showed that corneal thickness >450 μm, corneal curvature≤38 D, glucocorticoid treatment, intraoperative IOP fluctuation, corneal hysteresis ≤8.0 mm Hg (1 mm Hg=0.133 kPa), and intraoperative complications were the risk factors for the occurrence of high IOP after FS-LASIK surgery in patients with high myopia ( P<0.05). The C-index of the column-line graph prediction model based on this was 0.722 (95% confidence interval 0.684-0.760), the calibration curve and the ideal curve were basically the same, and the area under the ROC curve was 0.709. Conclusions:Corneal thickness> 450 μm, keratometric curvature ≤38 D, glucocorticoid treatment, intraoperative fluctuation of intraocular pressure, and corneal hysteresis ≤8.0 mm Hg are the risk factors for the development of hyperopic IOP in highly risk factors for the development of high IOP after FS-LASIK surgery in myopic patients. The column-line diagram model constructed on the basis of the risk factors hava good accuracy.

Stroke is one of the most common cerebrovascular diseases， including hemorrhagic stroke and ischemic stroke. From a modern medical perspective， stroke is caused by cerebrovascular damage or embolism leading to impaired blood circulation. From the traditional Chinese medicine （TCM） perspective， the pathogenesis of this disease is mainly due to the disorder of Qi and blood， which ascend to the brain， causing either blood extravasation or blockage of brain collaterals. Stasis is a pathological factor that runs throughout the entire course of stroke， and the method of promoting blood circulation and resolving stasis has been a core treatment for stroke for a long time. Hirudo， as a traditional insect drug， has shown good effects in promoting blood circulation and resolving stasis. Modern pharmacological research has confirmed that Hirudo contains anticoagulant components， which provide significant advantages in dissolving thrombi in ischemic stroke and facilitating hematoma absorption in hemorrhagic stroke. Hirudo and its related preparations have been proven to exert an anti-stroke effect through anticoagulation， anti-thrombosis， and protection of vascular endothelium. As a result， they have been widely used in the treatment of stroke. This article explored the theoretical basis and research status of using Hirudo for treating stroke based on its main active components and hemostatic properties and summarized the current research status of commonly used Hirudo-based formulations and preparations， aiming to provide references for the involvement of Hirudo in stroke treatment.

Objective:To explore the clinical characteristics, causes, diagnosis and treatment of transplant renal artery stenosis after pediatric-to-adult kidney transplantation.Methods:Between July 2014 and March 2019, clinical data were retrospectively reviewed for 25 en-bloc and 27 single kidney transplant cases.Results:One en-bloc(4.0%)and two single kidney recipients(7.4%)were diagnosed as renal artery stenosis at Month 13-23 months post-transplantation.It was higher than the rate of stenosis in adult-to-adult transplant cases(1.1%)during the same period.As compared with recipients without stenosis, stenotic ones had younger pediatric donors( P<0.05)and yet similar body weight of donors as well as recipients( P>0.05). The inner diameters of stenonotic sites were(1.40-1.63)mm and predominant stenotic site was proximal renal artery rather than anastomotic site.The remaining parts of major renal arteries varied from 2.31 to 4.93 mm in diameter.It was normal in children with a corresponding age.All three cases responded well to percutaneous transluminal angioplasty and stenting. Conclusions:The cause of stenosis may be an undeveloped local artery diameter due to extensive tissue dissection around artery.Therefore cautious selections of infantile single renal graft for adult recipients and preserving surrounding tissue of renal artery assist in the prevention of graft arterial stenosis.

Stroke is a common cerebrovascular disease， characterized by high incidence， mortality and disability rate. Neuronal cells， the basic unit of the central nervous system， can be injured to varying degrees when stroke occurs. Neuronal cell injury after stroke is also the key cause leading to neurological dysfunction， affecting the prognosis and quality of life of patients. Therefore， reducing the neuronal cell injury and delaying the process of cell death are effective to decrease the nerve function injury in stroke patients and improve their prognosis， thus lowering the death and disability rate of stroke. Ferroptosis is a new form of cell death that has been widely concerned in recent years. Several studies have confirmed that there is ferroptosis in neuronal cells after stroke. Since ferroptosis is an adjustable form， its intervention can help regulate the injury and death of neuronal cells. Studies have shown that inhibiting ferroptosis plays a role in protecting neuronal cells. Traditional Chinese medicine （TCM）， with the multi-channel and multi-target treatment advantages， has been widely used in the whole stroke and has achieved good clinical efficacy. It might be a new direction taking TCM regulation of ferroptosis as the entry point for stroke treatment in the future. This review revealed the mechanism of ferroptosis， discussed the research status of TCM in intervening in neuronal cell ferroptosis， and provided reference for further improving the efficacy of TCM in stroke.
