AIM:To investigate the effects of electroacupuncture at the Taiyang on refractive parameters and the expression of β-catenin and integrin β1 in the ciliary body of mice with form-deprivation myopia(FDM).METHODS:A total of 48 3-week-old healthy C57BL/6J mice were randomly divided into 4 groups: normal control(NC), FDM group, sham acupuncture(sham), and electroacupuncture at Taiyang acupoint(Taiyang), with 12 mice in each group. Mice in the FDM, sham, and Taiyang groups, wore translucent custom-made eye masks on the right eye to induce myopia. The Taiyang group received electroacupuncture stimulation at the Taiyang acupoint, while the sham group underwent non-penetrating stimulation with a blunt wooden stick. No intervention was performed on the NC group. Refraction and axial length were measured by infrared autorefractor and optical coherence tomography(OCT)before modeling and at 4 wk after modeling. The expression levels of β-catenin and integrin β1 in the ciliary body of mice at 4 wk after modeling were detected using quantitative real-time PCR(qPCR)and Western blotting(WB).RESULTS:After modeling for 4 wk, compared with the NC group, the FDM and sham groups showed significantly decreased refractive power(both P<0.05), elongated axial length(both P<0.05), and increased β-catenin and integrin β1 expression. Compared with the FDM and sham groups, the Taiyang group showed significantly increased refractive power(both P<0.05), shortened axial length(both P<0.05), and decreased β-catenin and integrin β1 expression.CONCLUSION:Electroacupuncture stimulation at the Taiyang acupoint effectively delayed the progression of myopia in FDM mice, and this effect may be partially mediated through modulating the expression of β-catenin and integrin β1 in the ciliary body.

Mycophenolic acid (MPA), the active moiety of both mycophenolate mofetil (MMF) and enteric-coated mycophenolate sodium (EC-MPS), serves as a primary immunosuppressant for maintaining solid organ transplants. Therapeutic drug monitoring (TDM) enhances treatment outcomes through tailored approaches. This study aimed to develop an evidence-based guideline for MPA TDM, facilitating its rational application in clinical settings. The guideline plan was drawn from the Institute of Medicine and World Health Organization (WHO) guidelines. Using the Delphi method, clinical questions and outcome indicators were generated. Systematic reviews, Grading of Recommendations Assessment, Development, and Evaluation (GRADE) evidence quality evaluations, expert opinions, and patient values guided evidence-based suggestions for the guideline. External reviews further refined the recommendations. The guideline for the TDM of MPA (IPGRP-2020CN099) consists of four sections and 16 recommendations encompassing target populations, monitoring strategies, dosage regimens, and influencing factors. High-risk populations, timing of TDM, area under the curve (AUC) versus trough concentration (C₀), target concentration ranges, monitoring frequency, and analytical methods are addressed. Formulation-specific recommendations, initial dosage regimens, populations with unique considerations, pharmacokinetic-informed dosing, body weight factors, pharmacogenetics, and drug‍-‍drug interactions are covered. The evidence-based guideline offers a comprehensive recommendation for solid organ transplant recipients undergoing MPA therapy, promoting standardization of MPA TDM, and enhancing treatment efficacy and safety.

The interaction between m⁶A-methylated RNA and chromatin modification remains largely unknown. We found that targeted inhibition of bromodomain-containing protein 4 (BRD4) by siRNA or its inhibitor (JQ1) significantly decreases mRNA m⁶A levels and suppresses the malignancy of breast cancer (BC) cells via increased expression of demethylase AlkB homolog 5 (ALKBH5). Mechanistically, inhibition of BRD4 increases the mRNA stability of ALKBH5 via enhanced binding between its 3' untranslated regions (3'UTRs) with RNA-binding protein RALY. Further, BRD4 serves as a scaffold for ubiquitin enzymes tripartite motif containing-21 (TRIM21) and ALKBH5, resulting in the ubiquitination and degradation of ALKBH5 protein. JQ1-increased ALKBH5 then demethylates mRNA of extra spindle pole bodies like 1 (ESPL1) and reduces binding between ESPL1 mRNA and m⁶A reader insulin like growth factor 2 mRNA binding protein 3 (IGF2BP3), leading to decay of ESPL1 mRNA. Animal and clinical studies confirm a critical role of BRD4/ALKBH5/ESPL1 pathway in BC progression. Further, our study sheds light on the crosstalks between histone modification and RNA methylation.

AIM: To investigate the effect of electroacupuncture on the expression of matrix metalloproteinase-3(MMP-3), tissue inhibitor of metalloproteinase-3(TIMP-3)and collagen type III alpha 1(Col3α1)in the retina of guinea pigs with lens-induced myopia.METHODS:A total of 80 guinea pigs were randomly divided into the normal control(NC)group, negative lens-induced myopia(LIM)group, electro-acupuncture(EA)group, and sham group, with 20 guinea pigs in each group. The NC group did not receive any intervention, the LIM, EA and the sham groups were all wearing -6.0 D lens in the right eye and no lens in the left eye. The EA group was given electroacupuncture stimulation at Hegu Point and temple, and guinea pigs in the sham group were given intervention at false points. The refraction was measured by optometry, the axial length was measured by A-ultrasound, and the changes in retinal tissue structure were observed by HE staining. Quantitative polymerase chain reaction(Q-PCR)and western blot(WB)were used to detect the expression of MMP-3, TIMP-3, and Col3α1 at mRNA and protein levels before modeling and at 2 and 4 wk after modeling. RESULTS:The axial length of the negative LIM group was significantly increased compared with the NC group at 2 and 4 wk after modeling(all P<0.05), and the diopter was significantly decreased(all P<0.05); the axial length of the eye in the EA group was decreased compared with the negative LIM group(all P<0.05), and the diopter was increased(all P<0.05). HE staining showed that the boundaries of retinal tissue in the NC group were obvious and arranged regularly. The retinal thickness, the thickness of the inner and outer nuclear layers, and the number of cells were reduced and irregularly arranged in the negative LIM group. The overall structure of the retina in the group EA was relatively perfect, the arrangement was more regular, and the morphological structure of each layer of the tissue did not appear obvious abnormalities. Q-PCR and WB detection results showed that the mRNA and protein relative expression levels of MMP-3, TIMP-3, and Col3α1 in the negative LIM group were significantly higher than those in the NC group(all P<0.05); the expression levels of the EA group was significantly decreased after intervention compared with the negative LIM group(all P<0.05).CONCLUSION: Electroacupuncture can delay axial growth in negative LIM guinea pigs, and downregulate negative LIM induced expression of MMP-3, TIMP-3, and Col3α1 in the retina.

Based on the pathogenesis of “tendon off-position and joint subluxation”， combined with modern ana-tomy and biomechanics， the characteristic manifestations of “tendon off-position” and “joint subluxation” of the knee and the intrinsic connection between them are clarified. Through sorting out the relationship between “tendon off-position and joint subluxation” and knee osteoarthritis （KOA） in modern research， it is believed that “tendon off-position and joint subluxation” is the key mechanism for the occurrence and development of KOA， and accordingly， it is proposed to take the diet as the guide， use bone manipulation for external diagnosis and treatment， use traditional Chinese medicine decoction for internal treatment， and use Daoyin exercise throughout the whole process as the strategy for KOA's comprehensive traditional Chinese medicine treatment to improve the clinical effectiveness.

Advances in imaging technology have revolutionized the field of ophthalmology, changing the understanding, diagnosis, and treatment of ophthalmic diseases. Swept-source optical coherence tomography(SS-OCT)is a non-contact high-resolution imaging technology. It further improves imaging depth and scanning speed, adds new algorithms and features. The application of SS-OCT enables the three-dimensional evaluation of corneal structures, offering curvature and height maps for both the anterior and posterior surfaces of the cornea, as well as precise corneal thickness mapping. These invaluable tools aid ophthalmologists in effectively screening and diagnosing various corneal lesions such as keratoconus, corneal dystrophy, and degeneration. Moreover, the enhanced speed, accuracy, and sensitivity provided by SS-OCT measurements facilitate improved surgical planning and postoperative monitoring for patients undergoing refractive surgery or keratoplasty. This article reviews the development of SS-OCT technology and its potential clinical utility in corneal diseases and surgical application, in order to support more possible future research and clinical treatment.

Objective:To observe the clinical effect of modified Shishi Niubangzi Decoction combined with strengthening muscle-waist exercise on lumbar disc herniation (LDH).Methods:Randomized controlled trial. A total of 60 patients with LDH admitted to the Pinggu Hospital, Beijing Traditional Chinese Medicine Hospital, were enrolled as the research objects between September 2020 and September 2021. According to the random number table, they were randomly divided into the treatment group and control group, 30 in each group. Both groups were given routine basic treatments (strengthening tendons-waist exercise and three-position six-step manipulation). On this basis, the treatment group was treated with modified Shishi Niubangzi Decoction, while the control group was treated with non-steroidal anti-inflammatory drugs (ibuprofen codeine sustained-release tablets). Both groups were treated for 4 weeks. The responsive rates, back pain intensity, leg pain and numbness by Visual Analogue Scale (VAS) and lumbar function by Oswestry Disability Index (ODI), and Japanese Orthopaedic Association (JOA) were compared between the two groups.Results:The response rate of treatment group was significantly higher than that of control group (93.3% vs. 73.3%; χ2=4.32, P=0.038). After treatment, scores of JOA (subjective symptoms, signs, activities of daily living) in the treatment group were significantly higher than those in the control group ( t=3.86, 2.71, 2.21, P<0.05). After treatment, scores of back pain (2.12±0.21 vs. 3.02±0.32, t=12.88), leg pain (2.04±0.64 vs. 2.64±0.66, t=3.58), lower limb numbness (1.75±0.24 vs. 2.41±0.70, t=4.89) in the treatment group were significantly lower than those in the control group ( P<0.01). At 1 week and 1 month after treatment, ODI scores in treatment group were significantly lower than those in control group ( t=10.22, 5.59; P<0.05). Conclusion:The modified Shishi Niubangzi Decoction combined with strengthening tendons-waist exercise can improve responsive rates, improve lumbar pain and function in LDH patients.

Objective:To detect the expression of MYBL2 gene in gastric adenocarcinoma tissue and its effects on cell proliferation and invasion. Methods:A total of 100 cases of gastric adenocarcinoma tissue and 100 cases of paracancerous tissue were selected from patients who received surgery in The People's Hospital of Yuhuan between January 2017 and December 2020. Gastric adenocarcinoma cell lines MGC-803 were transfected with MYBL2 siRNA and siRNA control. The cells not transfected were used as controls. MYBL2 gene expression in gastric adenocarcinoma tissue and paracancerous tissue as well as MGC-803 were determined by quantitative real time-polymerase chain reaction. MGC-803 cell proliferation was determined by MTT. The invasive ability of MGC-803 cells was determined by Transwell assay. The migration ability of MGC-803 cells was determined by Scratch testing. MYBL2 protein expression in gastric adenocarcinoma tissue and paracancerous tissue as well as MGC-803 cells was determined by western blotting. Results:The relative mRNA expression of MYBL2 in gastric adenocarcinoma tissue was significantly higher than that in paracancerous tissue [(0.65 ± 0.17) vs. (0.18 ± 0.05), t = 26.52, P < 0.05). The relative mRNA expression of MYBL2 in the MYBL2 siRNA group (0.29 ± 0.07) was significantly lower than that in the control group (0.73 ± 0.12) and siRNA group (0.71 ± 0.16, t = 5.48, 4.16, both P < 0.05). MTT assay showed that after 24 and 48 hours of culture, MGC-803 cell proliferation rate in the MYBL2 siRNA group [(40.95 ± 5.46)%, (52.12 ± 12.27)%] was significantly lower than that in the control group [(67.84 ± 6.45)%, (87.83 ± 9.96)%] and siRNA group [(66.98 ± 7.85)%, (85.98 ± 10.24)%, t = 5.51, 3.91, 4.71, 3.67, all P < 0.05]. MGC-803 cell invasion rate in the MYBL2 siRNA group [ (62.12 ± 6.43)%] was significantly lower than that in the control group [(89.74 ± 6.56)%] and siRNA group [(88.83 ± 7.85)%, t = 5.20, 4.55, both P < 0.05]. The number of MGC-803 cells migrated in the MYBL2 siRNA group [(4.32 ± 0.84) × 10 3] was significantly lower than that in the control group [(8.95 ± 1.64) × 10 3] and siRNA group [(8.83 ± 1.78) × 10 3, t = 4.35, 3.96, both P < 0.05]. The gray value of MYBL2 protein in the gastric adenocarcinoma tissue was (0.56 ± 0.15), which was significantly higher than that in the paracancerous tissue [(0.23 ± 0.07), t = 19.93, P < 0.001]. The gray value of MYBL2 protein in the MYBL2 siRNA group was (0.21 ± 0.03), which was significantly lower than that in the control group (0.67 ± 0.15) and siRNA group (0.65 ± 0.19) ( t = 5.20, 3.96, both P < 0.05). Conclusion:MYBL2 gene is highly expressed in gastric adenocarcinoma tissue. siRNA silencing MYBL2 can decrease the ability of MGC-803 cells to proliferate, invade and migrate and downregulate MYBL2 expression. This study is highly innovative and scientific.
