Background: s/Aims: Non-invasive models stratifying clinically significant portal hypertension (CSPH) are limited. Herein, we developed a new non-invasive model for predicting CSPH in patients with compensated cirrhosis and investigated whether carvedilol can prevent hepatic decompensation in patients with high-risk CSPH stratified using the new model. Methods: Non-invasive risk factors of CSPH were identified via systematic review and meta-analysis of studies involving patients with hepatic venous pressure gradient (HVPG). A new non-invasive model was validated for various performance aspects in three cohorts, i.e., a multicenter HVPG cohort, a follow-up cohort, and a carvediloltreating cohort. Results: In the meta-analysis with six studies (n=819), liver stiffness measurement and platelet count were identified as independent risk factors for CSPH and were used to develop the new “CSPH risk” model. In the HVPG cohort (n=151), the new model accurately predicted CSPH with cutoff values of 0 and –0.68 for ruling in and out CSPH, respectively. In the follow-up cohort (n=1,102), the cumulative incidences of decompensation events significantly differed using the cutoff values of <–0.68 (low-risk), –0.68 to 0 (medium-risk), and >0 (high-risk). In the carvediloltreated cohort, patients with high-risk CSPH treated with carvedilol (n=81) had lower rates of decompensation events than non-selective beta-blockers untreated patients with high-risk CSPH (n=613 before propensity score matching [PSM], n=162 after PSM). Conclusions Treatment with carvedilol significantly reduces the risk of hepatic decompensation in patients with high-risk CSPH stratified by the new model.

AIM: To investigate the effect of intense pulsed light(IPL)combined with meibomian gland massage in patients with meibomian gland dysfunction(MGD)related dry eye.METHODS: Retrospectively selected 300 cases(300 right eyes)that diagnosed as MGD-related dry eye and treated in our hospital from October 2021 to October 2023, and they were divided into two groups according to the treatment modalities: 150 cases(150 eyes)in the control group were treated with meibomian gland massage, and 150 cases(150 eyes)in the observation group were treated with combined IPL. The efficacy of the two groups was compared, as well as the changes in tear film stability indexes [tear film break-up time(BUT), Schirmer I test(SIT)], ocular surface disease index(OSDI)scores, tear film lipid layer thickness(LLT), mean objective scattering index(OSI), and the levels of inflammatory factors in the tear fluid [interleukin-10(IL-10)and IL-6].RESULTS: There was a difference in efficacy between the two groups of patients after treatment(88% vs 74%, P=0.002). At 8 wk after treatment, OSDI score, OSI, and tear IL-6 levels decreased, while BUT, SIt, LLT, and tear IL-10 levels increased in the two groups, and the observation group was better than the control group(all P<0.05).CONCLUSION: IPL combined with meibomian gland massage for the treatment of dry eye patients with MGD is therapeutically effective, improving corneal stability and LLT, and reducing levels of OSI and inflammatory factors.

Objective:To compare the effect of a 3D-printed ankle and foot orthosis (AFO) with that of a traditional AFO on the recovery of walking function after a stroke.Methods:Thirty-four hemiplegic stroke survivors were randomly divided into an observation group and a control group, each of 17. Both groups were taught good limb placement and given joint mobility, standing and walking training for 4 weeks wearing either a 3D-printed or a conventional AFO. Walking speed, walking endurance, and dynamic balance were evaluated before and after the experiment using the 10-metre walk test (10MWT), the 6-minute walk test (6MWT), and the timed up and go test (TUGT). Integrated electromyography (iEMG) was also performed on each subject′s bilateral rectus femoris, anterior tibialis, and gastrocnemius muscles during walking, and their healthy and affected side iEMG results were compared to assess the activation of the affected lower limb muscles.Results:After treatment, the 10MWT, 6MWT, and TUGT results of both groups had improved significantly, but the observation group′s average results were then significantly better than those in the control group. The iEMG disparities between the healthy and affected sides had also decreased significantly, but on average the disparities in the observation group were significantly smaller than in the control group.Conclusion:Both types of AFO can effectively improve the walking speed, walking endurance, and dynamic balance of hemiplegic stroke survivors and promote muscle activation in the affected lower limb. A 3D-printed AFO is relatively more effective.

AIM: To evaluate the damage to optic nerve by detecting the morphological and functional changes of optic nerve in patients with acute primary angle-closure glaucoma.METHODS: The correlation among the positive rates of fundus photography, visual field examination, optical coherence tomography(OCT)scan of the optic nerve, and pattern visual evoked potentials(P-VEP)were analyzed in 28 patients with acute primary angle-closure glaucoma affecting.RESULTS: Among 28 eyes of 28 patients, optic nerve images were obtained in 25 eyes(89%), optic disc color in 25 eyes: there were 9 normal eyes and 16 eyes with congestion and edema, without pallor; C/D: < 0.6 in 5 eyes, > 0.6 in 1 eye, and indistinguishable in 19 eyes; disk edge: 6 eyes were normal, and 19 eyes could not be distinguished.Optic nerve images could not be obtained in 3 eyes(11%). Visual field examination: 9 eyes(32%)were normal, 2 eyes(7%)had visual field damage, 8 eyes(29%)had no reference value due to cataract visual field examination, 2 eyes(7%)had false positive rate ≥15%, and 7 eyes(25%)could not cooperate with the examination. The retinal nerve fiber layer thickness around optic disc was measured by OCT in 26 eyes(93%), of which the thickness of nerve fiber layer was normal in 24 eyes and local thinning in 2 eyes. Severe opacification of refractive stroma could not be measured in 2 eyes(7%). PVEP showed that the peak of P100 was normal in 18 eyes(64%)and prolonged in 10 eyes(36%). The amplitude of P100 wave was normal in 11 eyes(39%)and decreased in 17 eyes(61%).CONCLUSION: After a major acute attack of primary angle-closure glaucoma, the optic nerve does not exhibit typical glaucomatous damage but may present with optic disc congestion and edema. Therefore, a comprehensive evaluation combining subjective and objective examination methods is necessary for optic nerve assessment, and currently, no more precise assessment method is available.

ObjectiveTo investigate the effect of myosin heavy chain 7 gene-derived miRNA-208b-3p on the fibrotic phenotype of cardiac fibroblasts. MethodsmiRNA chip array was performed to detect the dysregulated miRNAs in the myocardium of diabetic db/db mice and db/m control mice. Neonatal mouse ventricular cardiomyocytes （NMVCs） and cardiac fibroblasts （CFs） were isolated from C57BL/6 mice and cultured. Real-time quantitative PCR （RT-qPCR） was conducted to determine the expression of miR-208b-3p in mouse CFs and NMVCs subjected to angiotensinⅡ（AngⅡ） and high glucose plus glucose oxidase （G/Go） treatment， respectively. Cell counting kit 8（CCk8） assay， flow cytometry and determination of fibrosis-related protein， including COL1A1， COL3A1and α-SMA， were performed in mCFs transfected with miR-208b-3p. Dual luciferase reporter assay was performed to confirm the interaction between miR-208b-3p and the 3'-UTR of metal response element binding transcription factor 2 （Mtf2） and progesterone receptor membrane component 1（Pgrmc1）， respectively. The expressions of Mtf2 and Pgrmc1 at the mRNA and protein levels in mCFs after miR-208b-3p mimic transfection were determined using RT-qPCR and Western blot assay， respectively. The small interfering RNA （siRNA） was used to inhibit Mtf2 and Pgrmc1 expression in mCFs， and the effects of Mtf2 siRNA， Pgrmc1 siRNA and miR-208b-3p on fibrosis-related protein expression in mCFs were investigated. ResultsResults of miRNA chip array and RT-qPCR assay showed that miR-208b-3p was up-regulated in the myocardium of the diabetic db/db mice. miR-208b precursor and the host gene of Myh7 were consistently increased in db/db mice. miR-208b-3p and Myh7 mRNA were expressed in mCFs and NMVCs， but the levels of miR-208b-3p and Myh7 mRNA in NMVCs were much higher than those in mCFs. miR-208b-3p was up-regulated in mCFs and NMVCs subjected to Ang Ⅱ and G/Go treatment， respectively. miR-208b-3p could significantly enhance fibrosis-related protein， including COL1A1， COL3A1 and α-SMA， in mCFs， without affecting the proliferation activity and cell cycle distribution of mCFs. Dual luciferase reporter assay revealed the interactions of miR-208b-3p with the 3'-UTR of Mtf2 and Pgrmc1. The results of RT-qPCR and Western blotting confirmed that miR-208b-3p inhibited Mtf2 and Pgrmc1 expression at the post- transcriptional level. Transfection with miR-208b-3p mimic， Mtf2 siRNA and Pgrmc1 siRNA could consistently enhance the fibrosis-related protein expression in the cardiac fibroblasts. ConclusionsmiR-208b-3p enhances fibrosis-related gene expression by targeting Mtf2 and Pgrmc1in mCFs.

The application status of acupuncture and moxibustion therapy for assisted reproductive field in the United States was analyzed, and the existing problems and future development directions were discussed. According to the survey on the 456 websites of assisted reproductive clinic in the United States mentioned in the report of U.S. Centers for Disease Control and Prevention (CDC), 111 clinics among 456 assisted reproductive clinics recommend and used acupuncture and moxibustion therapy, accounting for 24.3%. Acupuncture and moxibustion therapy had obvious effect, good safety and low cost, and the assisted reproductive institutions in the United States had a high degree of application and recognition to acupuncture and moxibustion therapy. However, some problems, such as immature treatment scheme, unclear mechanism and imperfect insurance policies, still existed. In the future, the advantages of Chinese traditional acupuncture and moxibustion should combine with international modern assisted reproductive technology, and multi-center and large-sample clinical randomized controlled trials and basic experimental research on the mechanism of acupuncture and moxibustion for assisted reproduction should be carried out.
