Background: Visual impairment is increasingly prevalent, underscoring the need for effective prevention strategies. This study investigated the association between cardiovascular health and visual impairment using three progressively developed metrics: Life’s Simple 7 (LS7), a cardiovascular health score developed by the American Heart Association based on 7 components, including physical activity, smoking status, body mass index (BMI), diet, blood glucose, blood pressure, and total cholesterol; Life’s Essential 8(LE8), which adds sleep health as an additional component; and Life’s Crucial 9 (LC9), which further incorporates mental health. We aimed to evaluate whether these expanded metrics provide additional explanatory value and to inform future public health strategies. Objective: To investigate the associations among LS7, LE8, and LC9 cardiovascular health scores and visual impairment in National Health and Nutrition Examination Survey 2013 to 2018, assess the added value of sleep and mental health components, and identify key contributing subcomponents using regression and machine learning methods. Methods: We analyzed data from 9891 participants in the 2013 to 2018 National Health and Nutrition Examination Survey. Multivariable logistic regression, restricted cubic spline modeling, and subgroup analyses were conducted to evaluate the association between cardiovascular health and visual impairment. Machine learning methods, including Random Forest and SHapley Additive exPlanations, a model interpretation approach used to assess feature importance, were applied. The Boruta algorithm, a feature selection method, was used to identify key subcomponents of cardiovascular health. Results: Participants with visual impairment were older, had lower poverty-to-income ratios, and exhibited lower cardiovascular health scores (LS7, LE8, and LC9). Higher cardiovascular health scores were negatively associated with visual impairment. Each one standard deviation increase in LS7, LE8, and LC9 was associated with approximately 8%, 2%, and 3% lower odds of visual impairment, respectively. LS7 showed the strongest negative association, whereas LE8 and LC9 emerged as the most important predictors in the machine learning models. Key subcomponents such as blood glucose, blood pressure, and BMI, as well as mental health status, were strongly associated with visual impairment. Conclusion: Higher cardiovascular health scores were negatively associated with visual impairment. LS7 demonstrated the strongest statistical association, whereas LE8 and LC9 were the most influential features in the machine learning models. Blood glucose, blood pressure, BMI, and mental health status were important correlates of visual impairment. From the perspective of the “prevention and treatment of diseases” in traditional Chinese medicine and the holistic concept, the aforementioned research findings confirm that severe visual impairment is indeed an external manifestation of overall health imbalance (such as organ dysfunction and Qi deficiency and blood stasis). The prevention strategy lies in comprehensively adjusting lifestyle, emotional factors, and metabolic indicators (corresponding to the key factors in the study) to restore the body’s internal balance and achieve prevention before disease arises.

Knee osteoarthritis is a common joint disease within osteoarthritis,characterized by pain,swelling,and limited functionality as the main clinical manifestations.In severe cases,it affects daily life and falls under the category of"impediment syndrome"or"bone impediment"in TCM.The author believes that the theory of"bones,tendons,and muscles"is closely related to this disease.Treatment should focus on simultaneously nourishing the liver,spleen and kidneys,considering tendons,bones and muscles,while also dispelling wind,cold and dampness.The clinical application of Sanbi Decoction has shown good efficacy,and this discussion aimed to provide ideas for the diagnosis and treatment of knee osteoarthritis.

Objective:To compare the dosimetric parameters under different incremental modes between intensity-modulated radiation therapy(IMRT)and volume rotation intensity-modulated therapy(VMAT)for the target area of large volume brain metastases(BMs),and to explore the better way of treating BMs based on hypofractionated stereotactic radiotherapy(HSRT)of linear accelerator.Methods:A total of 30 BMs patients who underwent IMRT at The 971th Hospital of Navy of the CPLA from 2020 to 2023 were selected.In the treatment planning system(TPS),three types of IMRT plans and VMAT plans were designed,which included uniformity plan(Planuniformity)of target area dose,uniform increased plan(Planuniform increased-dose)and incremental plan(Planincremental)within target area.In the inside of the target area,the target area of high dose(GTVh)was set,and Planuniform increased-dose and Planincremental were designed to aim at GTVh.The differences of the doses of three types of treatment plans included Planuniformity,Planuniform increased-dose and Planincremental,which were respectively designed by using IMRT and VMAT,were analyzed.The mean dose(Dmean)of the target area,the 50%and 2%exposed doses(D50%and D2%)of the target area were observed and compared.The conformity index(CI),homogeneity index(HI),gradient index(GI),and the volume percentage(V10 Gy-V40 Gy)that normal brain tissue received 10 Gy-40 Gy also were observed and compared.Results:Compared with Planuniformity of IMRT,the Dmean of GTV of Planuniform increased-dose and Planincremental of IMRT increased by 10.13%and 17.9%,with statistically significant differences(t=13.680,12.771,P＜0.05).D50%increased by 8.9%and 10.8%,with statistically significant differences(t=15.190,9.929,P＜0.05).D2%increased by 15.2%and 46.4%,with statistically significant differences(t=52.320,8.746,P＜0.05).There were no statistically significant differences in normal brain tissue V10 Gy-V40 Gy among Planuniformity,Planuniform increased-dose and Planincremental of IMRT(P＞0.05).Compared with Planuniformity of VMAT,the Dmean of GTV of Planuniform increased-dose and Planincremental of VMAT increased by 10.53%and 21.23%,with statistically significant differences(t=18.641,15.461,P＜0.05),and D50%increased by 9.1%and 13.4%,with statistically significant differences(t=11.382,10.952,P＜0.05),and D2%increased by 16.4%and 48.8%,with statistically significant differences(t=56.471,8.685,P＜0.05),respectively.There were no statistically significant differences in normal brain tissue V10 Gy-V40 Gy among Planuniformity,Planuniform increased-dose and Planincremental of VMAT(P＞0.05).The normal brain tissue V20 Gy,V30 Gy and V40 Gy of Planuniform increased-dose and Planincremental of IMRT were respectively less than those of VMAT,and the differences of them between IMRT and VMAT were significant(tPlan uniform increased-dose=2.112,2.215,2.444,tPlan incremental=2.323,2.939,3.145,P＜0.05).There were no statistically significant difference in D2%,Dmean,and D50%between IMRT and VMAT(P＞0.05).Conclusion:On the premise of ensuring the safety of normal brain tissue at the edge of the target area,the synchronously increasing of the central dose of the target area will not significantly increase the dose for normal brain tissue.Both IMRT and VMAT can meet the requirements of increment in the inside of the target area,and VMAT has slightly better increment and higher efficiency within target area.The incremental of VMAT target area is slightly better,which also has better efficiency,while the enhancement effect of the dose of target area of Planincremental is better than that of the Planuniform increased-dose.The Plan incremental of VMAT is more suitable for HSRT treatment for BMs.

Objective:To explore the effect of family empowerment model on the improvement of swallowing care ability and care preparedness of primary caregivers of first-episode stroke dysphagia patients, further to explore its impact on patients′s wallowing function and life quality.Methods:This study was a randomized controlled study. From January 2021 to December 2022, 80 main caregivers of patients with dysphagia caused by manual stroke admitted to the Department of Acupuncture and Moxibustion, Shenzhen Hospital of Traditional Chinese Medicine were selected as the research objects, and 40 cases in the control group and 40 cases in the observation group were selected by random number table method. The control group were treated with conventional nursing care of first-episode stroke dysphagia patients in the acupuncture and moxibustion Department. On the basis of the conventional care in the control group, the observation group were treated with family empowerment model intervention for 14 days and was followed up for 28 days. Primary caregivers′ swallowing care ability, Caregiver Preparedness Scale (CPS), patients′ swallowing function rate, Swallowing Related Quality of Life (SWALQOL) were used to evaluate the effects before intervention and at the end of intervention.Results:There were 18 males and 19 females primary caregivers in the control group, aged (55.61 ± 7.43) years old. There were 18 males and 21 females primary caregivers in the observation group, aged (58.23 ± 8.22) years old. The swallowing care ability score showed a statistically significant difference between the observation group (143.47 ± 3.96) and the control group (107.74 ± 1.43) ( t=-26.76, P<0.05). After intervention, the caregiver preparedness scale was (26.11 ± 3.81) in the observation group, and (18.35 ± 4.54) in the control group, and the difference was statistically significant ( t=-4.11, P<0.05).The patients′ swallowing function rate and SWALQOL score were respectively 97.44% (38/39) and (91.41 ± 8.08) points in the observation group, and 72.97% (27/37) and (80.33 ± 4.21) points in the control group, and the difference was both statistically significant ( χ2=10.76, t=-2.54, both P<0.05). Conclusions:The implementation of family empowerment model could enhance the swallowing care ability and care preparedness of primary caregivers of the first-episode stroke dysphagia patients, which could further improve patients′ swallowing function and life quality.

Objective To analyze the causal relationship between serum sex steroid hormone levels and myopia with the Mendelian randomization(MR)methods.Methods Sex hormone genetic tools classified by sex were publicly availa-ble summarized statistical data from the Genome-wide association study(GWAS)of the UK Biobank Consortium on sex hormone-binding globulin(SHBG),total testosterone(TT),bioavailable testosterone(BT),and estradiol(E2).The GWAS summarized statistical data for myopia were obtained from publicly available data published by the FinnGen Consorti-um R10.All data were downloaded from April 18 to April 31,2024 from the corresponding databases and analyzed.All re-sults from the MR study were mainly analyzed by inverse-variance weighting(IVW)method.Results The study showed that a higher serum SHBG level in European increased the risk of myopia development in women(IVW,OR=1.152,95％CI:1.014-1.308,P=0.029);low serum TT level(IVW,OR=0.821,95％CI:0.697-0.967,P=0.018)and serum BT lev-el(IVW,OR=0.820,95％CI:0.691-0.972,P=0.022)increased the risk of myopia development in women.There was no causal relationship between serum SHBG,TT,and BT levels and myopia in men.There was no causal effect between E2 level and myopia in women and men.The stability of our findings was supported by sensitivity analysis.Conclusion In-creased serum SHBG level and decreased serum TT and BT levels are associated with an increased risk of myopia in women,whereas no such association is found in men.There is no causal relationship between E2 and myopia.

Objective:To investigate the consistency of domestic F-STROKE, NeuBrainCARE MRI automatic post-processing software and RAPID MRI automatic post-processing software in the output of infarction core area volume, time-to-maximum volume and ischemic penumbra volume in patients with acute ischemic stroke.Methods:The research was cross-sectional. The clinical and imaging data of patients with acute ischemic stroke from January 2016 to March 2021 were retrospectively collected, including 149 cases from Shanghai Fourth People′s Hospital Affiliated to Tongji University (Center 1), 120 cases from Langfang Changzheng Hospital of Hebei Province (Center 2), and 45 cases from Wuzhou Workers Hospital (Center 3). All patients underwent diffusion weighted imaging (DWI) and dynamic magnetic sensitivity contrast-perfusion weighted imaging (DSC-PWI). RAPID, F-STROKE and NeuBrainCARE automatic post-processing software were used to perform automatic post-processing analysis of MRI images of all patients with acute ischemic stroke. The infarct core (apparent diffusion coefficient<620×10 -6 mm 2/s) volume, time-to-maximum (T max>6 s) volume and the ischemic penumbra (PWI-DWI mismatch) volume were output. The Wilcoxon test was used to analyze the difference between F-STROKE, NeuBrainCARE, and RAPID software outputs of infarct core volume, time to maximum peak volume, and ischemic penumbra volume. Bland-Altman and intraclass correlation coefficient ( ICC) were used to analyze the consistency of the infarct core volume, time-to-maximum volume and ischemic penumbra volume output by F-STROKE, NeuBrainCARE and RAPID software. Results:There were statistically significant differences in the core infarct volume between F-STROKE and RAPID software, NeuBrainCARE and RAPID software ( Z=-10.17, -5.43, both P<0.001). There were significant differences in the time-to-maximum volume between F-STROKE and RAPID software, NeuBrainCARE and RAPID software ( Z=-3.17, -5.51, both P<0.05). There was no significant difference in the ischemic penumbra volume between F-STROKE software and RAPID software ( Z=-1.43, P=0.153), and there was significant difference in the ischemic penumbra volume between NeuBrainCARE software and RAPID software ( Z=-6.45, P<0.05). Bland-Altman analysis showed that the values within the limits of agreement accounted for more than 93.31% of all point values. ICC analysis showed high agreement between F-STROKE, NeuBrainCARE, and RAPID software outputs of infarct core volume, time to maximum peak volume, and ischemic penumbra volume ( ICC>0.6). Conclusion:Domestic F-STROKE software, NeuBrainCARE software and RAPID software have good consistency in evaluating the infarct core volume, time-to-maximum volume and ischemic penumbra volume in patients with acute ischemic stroke, which is worthy of clinical promotion.

This article introduces the guiding effect of three-dimensional visualization technique and its derivative technologies in the accurate diagnosis and preoperative evaluation of HAE, so as to provide help for the clinical diagnosis and treatment of HAE in the future.

Objective:To evaluate the efficacy of long-pulsed 1 064-nm Nd:YAG laser combined with a topical emulsion containing Camellia reticulata and Radix Notoginseng in the treatment of melasma. Methods:A total of 80 patients with melasma were enrolled from Department of Dermatology, People′s Hospital of Ningxia Hui Autonomous Region from June 2019 to June 2020, and randomly and equally divided into control group and observation group by using a random number table: 40 patients in the control group were treated with long-pulsed 1 064-nm Nd:YAG laser once every 2 weeks for 6 sessions as a course of treatment; another 40 in the observation group were treated with the same laser therapy as the control group and a topical emulsion containing Camellia reticulata and Radix Notoginseng twice a day for 3 months as a course of treatment. Melasma area and severity index (MASI), clinical efficacy, patient satisfaction rate and safety were compared between the 2 groups before and/or after treatment. Results:After 4- and 8-week treatment, there was no significant difference in the MASI score between the observation group (14.57 ± 3.22 points, 10.00 ± 2.94 points, respectively) and control group (14.74 ± 3.11 points, 11.31 ± 3.00 points, respectively; both P>0.05). After 12-week treatment, the MASI score was significantly lower in the observation group (4.80 ± 2.78 points) than in the control group (7.07 ± 3.22 points, t = -3.38, P<0.01). After 3-month treatment, the response rate was significantly higher in the observation group (36 cases, 90%) than in the control group (31 cases, 77.5%; χ2 = 4.58, P < 0.001) ; however, there was no significant difference in the patient satisfaction rate between the observation group (87.5%) and control group (72.5%, χ2 = 7.26, P = 0.06). In addition, no significant difference in the occurrence of adverse reactions was observed between the observation group (5 cases, 12.5%) and control group (7 cases, 17.5%; P > 0.05) . Conclusion:Compared with the long-pulsed 1 064-nm Nd:YAG laser alone, the topical emulsion containing Camellia reticulata and Radix Notoginseng in combination with the long-pulsed 1 064-nm Nd:YAG laser is more effective for the treatment of melasma, with higher patient satisfaction and less adverse reactions.
