Amblyopia is a common visual development disorder and is the main cause of monocular vision impairment in children and adults. Photobiomodulation(PBM), a non-invasive treatment method, has gradually gained attention in the field of ophthalmology. This paper begins with the macroscopic manifestation of light on the animal model of amblyopia. Additionally, it discusses the pathological changes of the amblyopic retina and the human eye's central nervous system, as well as the influence and mechanism of PBM on the visual perception and processing system and its chemical effect on the visual system through dopamine and melatonin. It examines its mechanism of action, current clinical application status, and future development direction in order to provide new ideas and theoretical foundation for amblyopia treatment.

Purpose: This study identified risk factors for neurogenic lower urinary tract dysfunction (NLUTD) in patients with acute ischemic stroke (AIS) through multidimensional analysis of the medical records of patients, aiming to reduce the incidence of NLUTD, improve prognosis, and facilitate rehabilitation. Materials and Methods: In this case-control study, patients with AIS were recruited from two tertiary general hospitals in Shenzhen, China, from March 2021 to October 2023. Patients were divided into NLUTD and non-NLUTD groups based on the presence and absence of NLUTD, respectively. Comparative analysis was performed using the Mann–Whitney U and chi-square tests, with significant variables being included in logistic regression analysis. Results: Of the 652 participants enrolled in this study, 119 participants (18.3%) developed NLUTD. Bivariate analysis showed that 39 of 54 screened factors exhibited a significant correlation (p<0.05) with the incidence of NLUTD after AIS. Significant variables identified through logistic regression analysis included Glasgow coma scale (GCS) and National Institutes of Health Stroke Scale (NIHSS) scores, anemia, aphasia, pneumonia, brainstem involvement, multiple lesions, urine clarity (CLA), random venous blood glucose (GLU) and hemoglobin (HGB) levels, and white blood cell (WBC) count. Conclusions A total of 11 risk factors for NLUTD were identified in this study. This finding provides valuable guidance for reducing the incidence of NLUTD after AIS and improving the quality of life of patients.

Alcoholic liver disease (ALD) is a growing global health concern, and its early pathogenesis includes steatosis and steatohepatitis. Inhibiting lipid accumulation and inflammation is a crucial step in relieving ALD. Evidence shows that puerarin (Pue), an isoflavone isolated from Pueraria lobata, exerts cardio-protective, neuroprotective, anti-inflammatory, antioxidant activities. However, the therapeutic potential of Pue on ALD remains unknown. In the study, both the NIAAA model and ethanol (EtOH)-induced AML-12 cell were used to explore the protective effect of Pue on alcoholic liver injury in vivo and in vitro and related mechanism. The results showed that Pue (100 mg·kg^-1) attenuated EtOH-induced liver injury and inhibited the levels of SREBP-1c, TNF-α, IL-6 and IL-1β, compared with silymarin (Sil, 100 mg·kg^-1). In vitro results were consistent within vivo results. Mechanistically, Pue might suppress liver lipid accumulation and inflammation by regulating MMP8. In conclusion, Pue might be a promising clinical candidate for ALD treatment.

Five new saponins, including three steroid saponins, paristenoids A-C (1-3), and two triterpenoid saponins, paristenoids D-E (4-5), along with four known ones (6-9) were isolated from the rhizomes of Paris polyphylla var. stenophylla. The structures of the isolated compounds were identified mainly by detailed spectroscopic analysis, including extensive 1D and 2D NMR, MS, as well as chemical methods. Compound 3 is a new cyclocholestanol-type steroidal saponin with a rare 6/6/6/5/5 fused-rings cholestanol skeleton, and this skeleton has been first found from the genus Paris. The cytotoxicities of the isolated compounds against three human three glioma cell lines (U87MG, U251MG and SHG44) were evaluated, and compound 7 displayed certain inhibitory effect with IC₅₀ values of 15.22 ± 1.73, 18.87 ± 1.81 and 17.64 ± 1.69 μmol·L^-1, respectively.

Objective: To investigate the proteomic characteristics of overweight/obesity and related abnormal glucose and lipid metabolism caused by phlegm-dampness retention to identify related biomarkers. Methods: Seventy-one subjects were enrolled in the study. We assessed blood glucose, blood lipids, body mass index (BMI), and phlegm-dampness pattern, which was confirmed by a traditional Chinese med-icine clinician. Of the participants, we included healthy participants with normal weight (NW, n =23), overweight/obese participants with normal metabolism (ONM, n = 19), overweight/obese participants with pre-diabetes (OPD, n = 12), and overweight/obese participants with marginally-elevated blood lipids (OML, n = 17). Among them, the ONM, OPD, and OML groups were diagnosed with phlegm-dampness pattern. The data-independent acquisition (DIA) method was first used to analyze the plasma protein expression of each group, and the relevant differential proteins of each group were screened. The co-expressed proteins were evaluated by Venn analysis. The pathway analyses of the differential proteins were analyzed using Ingenuity Pathway Analysis (IPA) software. Parallel reaction monitoring (PRM) was used to verify the differential and common proteins in each group. Results: After comparing ONM, OPD, and OML groups with NW group, we identified the differentially expressed proteins (DEPs). Next, we determined the DEPs among OPD, OML, and ONM groups. Using Venn analysis of the DEPs in each group, 24 co-expressed proteins were screened. Two co-expressed proteins were verified by PRM. IPA analysis showed that pathways including LXR/RXR activation, acute phase response signaling, and FXR/RXR activation were common to all three groups of phlegm-damp overweight/obesity participants. However, the activation or inhibition of these pathways was different among the three groups. Conclusion: Participants with overweight/obesity have similar proteomic characteristics, though each type shows specific proteomic characteristics. Two co-expressed proteins, VTN and ORM1, are potential biomarkers for glucose and lipid metabolism diseases with overweight/obesity caused by phlegm-dampness retention.

OBJECTIVE: To observe the therapeutic effect of different doses of dihydroartemisinin (DHA) on atopic dermatitis (AD) in mice and explore the mechanism. METHODS: Forty-two C57BL/6 mice were randomly divided into 7 groups ( RESULTS: Treatment with 25, 75, and 125 mg/kg DHA and dexamethasone all alleviated AD symptoms of mice, reduced the severity scores of skin lesions, and ameliorated pathological changes of the skin tissue. DHA at 125 mg/kg produced the most obvious therapeutic effect and significantly alleviated mast cell infiltration in the lesions as compared with the other treatment groups ( CONCLUSIONS DHA is effective for the treatment of AD in mice with an optimal dose of 125 mg/kg. The therapeutic effect of DHA is achieved probably through regulation of local immunity by inhibiting mast cell infiltration in the lesions.

The results of Western blotting and immunofluorescence revealed clear presence of the expressed proteins. CONCLUSION Eukaryotic expression vectors for ABO subgroup genes were successfully constructed and worked well in Hela cells in vitro, which can facilitate further study of the ABO blood group proteins.

Objective To observe the effects of dual-task motor training on motor and balance function for stroke patients. Methods From January, 2016 to June, 2017, 30 patients with stroke were assigned randomly into control group (n = 15) and treatment group (n = 15). Both groups accepted routine physical therapy, the control group accepted anti-gravity treadmill training, while the treatment group accepted dual-task training with anti-gravity treadmill, for four weeks. They were measured with balance training and evaluation system, and assessed with Fugl-Meyer Assessment-lower extremity (FMA-L), Berg Balance Scale (BBS) and modified Barthel Index (MBI), before and after treatment. Results The range of swaying on X axial (Rx) and Y axial (Ry), as well as rectangle area (RecArea) decreased after treatment in the treatment group (t > 4.719, P < 0.001), while RecArea decreased in the control group (t = 5.069, P < 0.001). Ry and RecArea were less in the treatment group than in the control group (t > 2.288, P < 0.05). The scores of FMA-L, BBS and MBI improved after treatment in both groups (t > 7.316, P < 0.001), and improved more in the treatment group than in the control group (t > 2.322, P < 0.05). Conclusion The dual-task training via anti-gravity treadmill may improve motor and balance function in stroke patients, and promote the activities of daily living.

Objective To observe the effect of kinesthetic imagery and visual imagery on upper limb rehabilitation among stroke survivors.Methods Forty-five hemiplegic stroke survivors were randomly assigned into a kinesthetic imagery training group (n=14),a visual imagery training group (n=15) or a control group (n=16).In addition to conventional rehabilitation,patients in the kinesthetic and visual imagery training groups were given 30 minutes of the appropriate imagery training once a day,five days per week for four weeks,while the control group relaxed or received health education for the same time.Before and after the 4-week intervention,the upper limb section of the Fugl-Meyer assessment (FMA-UE) and the modified Barthel index (MBI) were used to evaluate the motor function of the subjects' upper limb and their ability in the activities of daily living respectively.Results Before the intervention,there were no significant differences in the average FMA-UE and MBI scores among the 3 groups.After the intervention there was no significant difference between the average FMA-UE and MBI scores of the two training groups,but both were significantly better than the control group's averages.Conclusion Either kinesthetic or visual imagery training can improve the upper limb function of stroke survivors and their abihty in the activities of daily living.Their effectiveness is not significantly different.
