AIM: To investigate the influence of relevant inflammatory markers in peripheral blood on the progression of neovascular glaucoma(NVG)secondary to diabetic retinopathy(DR)patients.METHODS: Retrospective case-control study. Patients were categorized into two groups based on the presence or absence of NVG: those with proliferative diabetic retinopathy(PDR)alone(PDR group, n=148)and those with NVG secondary to PDR(NVG secondary to PDR group, n=142). Peripheral blood inflammatory markers were evaluated, including white blood cell-related indices, neutrophil-to-lymphocyte ratio(NLR), platelet-to-lymphocyte ratio(PLR), monocyte-to-lymphocyte ratio(MLR), and systemic immune-inflammation index(SII). The distinctions in peripheral blood inflammatory markers between the two groups of patients and their relationships with NVG secondary to PDR were analyzed.RESULTS:No statistically significant differences were observed in basic characteristics between the two groups, confirming their comparability. However, significant differences were found in eosinophil percentage and MLR between the PDR group and the NVG secondary to PDR group(all P<0.05), with both values being significantly higher in the NVG secondary to PDR group. Multivariate Logistic regression analysis revealed that the eosinophil percentage and the MLR were factors influencing the development of patients with NVG secondary to PDR.CONCLUSION: Eosinophil percentage and MLR may be associated with the progression of PDR to NVG, and could serve as potential predictive markers for NVG development in PDR patients.

Objective:To characterize COVID-19-associated skin diseases and explore their influencing factors.Methods:A cross-sectional survey was conducted via the online platform Wenjuanxing in Changsha area from February 16, 2023, to March 16, 2023. The convenience sampling method was employed to conduct a survey of outpatients with a history of COVID-19 infection from the Second Affiliated Hospital of Hunan University of Chinese Medicine, as well as individuals in certain areas of Changsha who met the inclusion criteria for past COVID-19 infections. Demographic characteristics, COVID-19 infection details, and the occurrence of skin conditions after COVID-19 infection were collected. The chi-square test was used for inter-group comparisons of categorical data, and multivariate logistic regression analysis was performed to investigate factors associated with skin diseases following COVID-19 infection.Results:A total of 357 valid questionnaires were collected, and 357 patients with a history of COVID-19 infection were involved, including 246 females (68.9%) and 111 males (31.1%). Among these patients, 260 (72.8%) were aged ≤ 35 years. After COVID-19 infection, skin diseases occurred in 96 patients (26.9%), with urticaria (27 cases, 31.0%), rosacea (27 cases, 31.0%), hair loss (18 cases, 20.7%), and Henoch-Sch?nlein purpura (15 cases, 17.2%) being the most common diseases. Additionally, 96 patients (26.9%) had a history of pre-existing skin diseases, among whom 36 experienced exacerbation of their pre-existing skin diseases due to COVID-19 infection. Univariate analysis showed that gender, history of chronic diseases, history of allergic diseases, COVID-19 vaccination, duration of COVID-19 infection, and exacerbation of pre-existing skin diseases were significantly associated with the development of new skin diseases following COVID-19 infection (all P < 0.05). Multivariate logistic regression analysis revealed that gender (compared with females, males: OR = 0.235, 95% CI: 0.113, 0.490), history of allergic diseases (compared with patients without a history of allergic diseases, those with the history: OR = 2.159, 95% CI: 1.239, 3.761), and duration of COVID-19 infection (compared with the duration of < 5 days, duration of 6 - 7 days: OR = 3.043, 95% CI: 1.495, 6.193; duration of 8 - 14 days: OR = 2.364, 95% CI: 1.105, 5.506; duration of ≥ 15 days: OR = 4.406, 95% CI: 1.972, 9.849) were influencing factors for skin diseases after COVID-19 infection (all P < 0.05) . Conclusions:COVID-19 infection may lead to skin diseases such as urticaria, rosacea, hair loss, and Henoch-Sch?nlein purpura. Females, individuals with a history of allergic diseases, and those with a relatively long duration of COVID-19 infection were more prone to develop skin diseases after COVID-19 infection.

Objective:To preliminarily explore therapeutic effects and possible molecular mechanisms of sinomenine on atopic dermatitis (AD) -like mouse models.Methods:Thirty female BALB/c mice (6 - 8 weeks old) were randomly divided into 5 groups: blank control group, model group, positive control group, topical sinomenine group, and oral sinomenine group. Except for the blank control group, all groups were subjected to repeated topical stimulation with 2,4-dinitrochlorobenzene (DNCB) on the dorsal skin to establish an AD-like mouse model. After modeling, no special treatment was given to the blank control group, the positive control group was topically treated with 100 μg of 0.1% mometasone furoate cream twice daily on the lesions, the topical sinomenine group was topically treated with 100 μl of 10 mg/ml sinomenine solution twice daily on the lesions, and the oral sinomenine group was gavaged with sinomenine solution at a dose of 100 mg·kg -1·d -1 (100 μl per dose, twice daily) . Treatments lasted for 14 days. Twelve hours after the final treatment, the severity of skin lesions in each group was assessed. Blood samples were collected via enucleation, and serum levels of interleukin (IL) -1β, IL-6, and immunoglobulin E (IgE) were measured using enzyme-linked immunosorbent assay (ELISA) . Histopathological changes in dorsal skin lesions were observed, and immunohistochemical study was performed to detect the expression levels of p38 mitogen-activated protein kinase (MAPK) and nuclear factor (NF) -κB p65 in skin tissues, expressed as the percentage of the immunopositive area. One-way analysis of variance was used for multiple group comparisons, while Tukey′s test or the Games-Howell test was applied for post-hoc comparisons between groups. Results:Compared with the blank control group, the model group exhibited epidermal hyperkeratosis with parakeratosis, thickening of the spinous layer, spongiosis, significant inflammatory cell infiltration, and prominent angiogenesis. In contrast, the positive control group, topical sinomenine group, and oral sinomenine group showed reduced spinous layer thicknesses, decreased inflammatory cell infiltration, and less pronounced angiogenesis compared to the model group. In the blank control group, model group, positive control group, topical sinomenine group, and oral sinomenine group, the severity scores of skin lesions were 0, 8.83 ± 0.75, 4.33 ± 1.08, 2.58 ± 0.49, 2.83 ± 0.93 respectively, the serum levels of IL-1β were 52.58 ± 1.72, 168.40 ± 7.23, 57.07 ± 6.39, 85.74 ± 4.15, 100.30 ± 11.55 pg/ml respectively, IL-6 levels were 86.88 ± 4.60, 215.00 ± 5.02, 79.34 ± 4.91, 127.20 ± 1.06, 149.00 ± 6.21 pg/ml respectively, IgE levels were 2 159.00 ± 176.00, 3 493.00 ± 89.61, 2 294.00 ± 158.10, 2 550.00 ± 214.70, 2 814.00 ± 119.70 μg/ml respectively, the expression levels of p38 MAPK in skin tissues were 3.03% ± 3.38%, 12.95% ± 6.89%, 2.14% ± 1.28%, 5.28% ± 3.71%, 3.85% ± 2.26% respectively, and NF-κB p65 expression levels were 0.61% ± 0.49%, 18.92% ± 6.96%, 3.77% ± 1.90%, 5.66% ± 2.28%, 6.25% ± 3.14% respectively; the differences in all the above parameters were statistically significant among groups (all P < 0.05) . Compared with the blank control group, the model group had significantly increased skin lesion severity scores, serum IL-1β, IL-6, and IgE levels, as well as elevated expression of p38 MAPK and NF-κB p65 in skin tissues (all P < 0.01) . Compared with the model group, the positive control group, topical sinomenine group, and oral sinomenine group showed significantly reduced skin lesion severity scores, decreased serum IL-1β, IL-6, and IgE levels, and lower expression of p38 MAPK and NF-κB p65 in skin tissues (all P < 0.05) . Compared with the positive control group, the topical and oral sinomenine groups exhibited further reductions in skin lesion severity scores (both P < 0.05) . Additionally, the topical sinomenine group showed significantly lower serum levels of IL-1β and IL-6 compared with the oral sinomenine group (both P < 0.05) . Conclusion:Sinomenine solution could obviously alleviate the severity of skin lesions in AD-like mouse models, likely by down-regulating the expression of IL-1β, IL-6 and IgE, inhibiting the MAPK/NF-κB signaling pathway, and thus reducing the degree of inflammation.

Objective To investigate the influencing factors related to the severity of tinnitus with normal hearing and to provide a clinical basis for the treatment of such patients.Methods From November 2019 to May 2020,150 normal hearing patients with tinnitus as their first chief complain in the outpatient clinic of our center were selected.The severity of tinnitus was assessed by the tinnitus handicap inventory(THI),and the quality of sleep and psychological condition were assessed by the Pittsburgh sleep quality index inventory(PSQI)and the anxie-ty and depression scale(HADS).The relationship between tinnitus severity and patients'gender,age,duration of illness,tinnitus side,tinnitus dominant sound frequency,tinnitus dominant sound loudness,sleep quality,anxiety and depression were analyzed using Pearson's method and Logistic multi-factor regression.Results The Pearson correlation analysis suggested that sleep quality(r=0.667,P＜0.001),anxiety status(r=0.603,P＜0.001)and depression status(r=0.593,P＜0.001)were correlated with the THI classification,and patients with poorer sleep quality and higher anxiety and depression scores had more severe tinnitus.Logistic multi-factor regression analysis showed that only sleep quality had a significant effect on THI classification(P＜0.001).Conclusion Sleep quality may be related to the severity of tinnitus patients with normal hearing,and it is important to focus on their sleep sta-tus in the clinical management of such patients.

Objective:To investigate the effects of multimodal and multisensory stimulation training on feeding-swallowing and neurological functions in stroke patients with dysphagia.Methods:Stroke patients with dysphagia treated at Henan Provincial People's Hospital from January 2023 to October 2024 were enrolled. Patients were randomly divided into three groups according to the random number table method, with 36 patients in each group. These three groups underwent different interventions for a period of 8 weeks: multisensory stimulation intervention (stimulation group), multimodal rehabilitation training intervention (rehabilitation group), and innovative multimodal and multisensory stimulation training intervention (combined group). The Kubota water swallow test and functional oral intake scale (FOIS) were used to assess the effective improvement rate of feeding function. Differences in scores of modified Mann assessment of swallowing (MMASA), swallowing quality of life (SWAL-QOL), and National Institute of Health Stroke scale (NIHSS) among the three groups were compared before intervention, and at 4 and 8 weeks post-intervention. SPSS 27.0 software was used to analyze the data by one-way ANOVA, repeated measures ANOVA, Kruskal-Wallis H test, Mann-Whitney U test and Pearson correlation analysis. Results:(1) After 8 weeks of intervention, the effective improvement rates of feeding function were 75.00%(27/36) and 72.22%(26/36) in the stimulation group and rehabilitation group, respectively, which were both lower than that in the combined group (94.44%(34/36), both P<0.05). (2) The interaction effect between time and group was significant in MMASA scores among the three groups before and after intervention ( F=2.569, P<0.05). MMASA scores at 8 weeks post-intervention were higher than those at 4 weeks post-intervention and baseline in all groups (all P<0.05), and scores at 4 weeks post-intervention were also higher than those at baseline (all P<0.05). At 4 and 8 weeks post-intervention, MMASA scores in the combined group (85.64±11.26, 92.56±10.55) were higher than those in the stimulation group (73.52±12.65, 82.97±12.84) and rehabilitation group (72.47±11.38, 84.39±12.29) (all P<0.05). (3) The interaction effect between time and group was significant in SWAL-QOL total scores among the three groups before and after intervention ( F=18.561, P<0.05). SWAL-QOL total scores at 8 weeks post-intervention were higher than those at 4 weeks post-intervention and baseline in all groups ( P<0.05), and scores at 4 weeks post-intervention were also higher than those at baseline (all P<0.05). At 4 and 8 weeks post-intervention, SWAL-QOL total scores in the combined group (115.64±9.26, 135.68±9.55) were higher than those in the stimulation group (108.42±8.65, 113.75±8.84) and rehabilitation group (108.37±8.38, 114.39±9.29) (all P<0.05). (4) The interaction effect between time and group was significant in NIHSS scores among the three groups before and after intervention ( F=7.890, P<0.05). NIHSS scores at 8 weeks post-intervention were lower than those at 4 weeks post-intervention and baseline in all groups (all P<0.05), and scores at 4 weeks post-intervention were also lower than those at baseline (all P<0.05). At 4 and 8 weeks post-intervention, NIHSS scores in the combined group (8.36±1.35, 5.22±1.05) were lower than those in the stimulation group (11.65±2.11, 8.78±1.12) and rehabilitation group (11.32±2.03, 8.36±1.17) (all P<0.05). Conclusion:Multimodal and multisensory stimulation training can improve feeding-swallowing function and neurological impairment in stroke patients with dysphagia, with intervention effects superior to those of either approach used alone.

Objective:To characterize COVID-19-associated skin diseases and explore their influencing factors.Methods:A cross-sectional survey was conducted via the online platform Wenjuanxing in Changsha area from February 16, 2023, to March 16, 2023. The convenience sampling method was employed to conduct a survey of outpatients with a history of COVID-19 infection from the Second Affiliated Hospital of Hunan University of Chinese Medicine, as well as individuals in certain areas of Changsha who met the inclusion criteria for past COVID-19 infections. Demographic characteristics, COVID-19 infection details, and the occurrence of skin conditions after COVID-19 infection were collected. The chi-square test was used for inter-group comparisons of categorical data, and multivariate logistic regression analysis was performed to investigate factors associated with skin diseases following COVID-19 infection.Results:A total of 357 valid questionnaires were collected, and 357 patients with a history of COVID-19 infection were involved, including 246 females (68.9%) and 111 males (31.1%). Among these patients, 260 (72.8%) were aged ≤ 35 years. After COVID-19 infection, skin diseases occurred in 96 patients (26.9%), with urticaria (27 cases, 31.0%), rosacea (27 cases, 31.0%), hair loss (18 cases, 20.7%), and Henoch-Sch?nlein purpura (15 cases, 17.2%) being the most common diseases. Additionally, 96 patients (26.9%) had a history of pre-existing skin diseases, among whom 36 experienced exacerbation of their pre-existing skin diseases due to COVID-19 infection. Univariate analysis showed that gender, history of chronic diseases, history of allergic diseases, COVID-19 vaccination, duration of COVID-19 infection, and exacerbation of pre-existing skin diseases were significantly associated with the development of new skin diseases following COVID-19 infection (all P < 0.05). Multivariate logistic regression analysis revealed that gender (compared with females, males: OR = 0.235, 95% CI: 0.113, 0.490), history of allergic diseases (compared with patients without a history of allergic diseases, those with the history: OR = 2.159, 95% CI: 1.239, 3.761), and duration of COVID-19 infection (compared with the duration of < 5 days, duration of 6 - 7 days: OR = 3.043, 95% CI: 1.495, 6.193; duration of 8 - 14 days: OR = 2.364, 95% CI: 1.105, 5.506; duration of ≥ 15 days: OR = 4.406, 95% CI: 1.972, 9.849) were influencing factors for skin diseases after COVID-19 infection (all P < 0.05) . Conclusions:COVID-19 infection may lead to skin diseases such as urticaria, rosacea, hair loss, and Henoch-Sch?nlein purpura. Females, individuals with a history of allergic diseases, and those with a relatively long duration of COVID-19 infection were more prone to develop skin diseases after COVID-19 infection.

Objective:To preliminarily explore therapeutic effects and possible molecular mechanisms of sinomenine on atopic dermatitis (AD) -like mouse models.Methods:Thirty female BALB/c mice (6 - 8 weeks old) were randomly divided into 5 groups: blank control group, model group, positive control group, topical sinomenine group, and oral sinomenine group. Except for the blank control group, all groups were subjected to repeated topical stimulation with 2,4-dinitrochlorobenzene (DNCB) on the dorsal skin to establish an AD-like mouse model. After modeling, no special treatment was given to the blank control group, the positive control group was topically treated with 100 μg of 0.1% mometasone furoate cream twice daily on the lesions, the topical sinomenine group was topically treated with 100 μl of 10 mg/ml sinomenine solution twice daily on the lesions, and the oral sinomenine group was gavaged with sinomenine solution at a dose of 100 mg·kg -1·d -1 (100 μl per dose, twice daily) . Treatments lasted for 14 days. Twelve hours after the final treatment, the severity of skin lesions in each group was assessed. Blood samples were collected via enucleation, and serum levels of interleukin (IL) -1β, IL-6, and immunoglobulin E (IgE) were measured using enzyme-linked immunosorbent assay (ELISA) . Histopathological changes in dorsal skin lesions were observed, and immunohistochemical study was performed to detect the expression levels of p38 mitogen-activated protein kinase (MAPK) and nuclear factor (NF) -κB p65 in skin tissues, expressed as the percentage of the immunopositive area. One-way analysis of variance was used for multiple group comparisons, while Tukey′s test or the Games-Howell test was applied for post-hoc comparisons between groups. Results:Compared with the blank control group, the model group exhibited epidermal hyperkeratosis with parakeratosis, thickening of the spinous layer, spongiosis, significant inflammatory cell infiltration, and prominent angiogenesis. In contrast, the positive control group, topical sinomenine group, and oral sinomenine group showed reduced spinous layer thicknesses, decreased inflammatory cell infiltration, and less pronounced angiogenesis compared to the model group. In the blank control group, model group, positive control group, topical sinomenine group, and oral sinomenine group, the severity scores of skin lesions were 0, 8.83 ± 0.75, 4.33 ± 1.08, 2.58 ± 0.49, 2.83 ± 0.93 respectively, the serum levels of IL-1β were 52.58 ± 1.72, 168.40 ± 7.23, 57.07 ± 6.39, 85.74 ± 4.15, 100.30 ± 11.55 pg/ml respectively, IL-6 levels were 86.88 ± 4.60, 215.00 ± 5.02, 79.34 ± 4.91, 127.20 ± 1.06, 149.00 ± 6.21 pg/ml respectively, IgE levels were 2 159.00 ± 176.00, 3 493.00 ± 89.61, 2 294.00 ± 158.10, 2 550.00 ± 214.70, 2 814.00 ± 119.70 μg/ml respectively, the expression levels of p38 MAPK in skin tissues were 3.03% ± 3.38%, 12.95% ± 6.89%, 2.14% ± 1.28%, 5.28% ± 3.71%, 3.85% ± 2.26% respectively, and NF-κB p65 expression levels were 0.61% ± 0.49%, 18.92% ± 6.96%, 3.77% ± 1.90%, 5.66% ± 2.28%, 6.25% ± 3.14% respectively; the differences in all the above parameters were statistically significant among groups (all P < 0.05) . Compared with the blank control group, the model group had significantly increased skin lesion severity scores, serum IL-1β, IL-6, and IgE levels, as well as elevated expression of p38 MAPK and NF-κB p65 in skin tissues (all P < 0.01) . Compared with the model group, the positive control group, topical sinomenine group, and oral sinomenine group showed significantly reduced skin lesion severity scores, decreased serum IL-1β, IL-6, and IgE levels, and lower expression of p38 MAPK and NF-κB p65 in skin tissues (all P < 0.05) . Compared with the positive control group, the topical and oral sinomenine groups exhibited further reductions in skin lesion severity scores (both P < 0.05) . Additionally, the topical sinomenine group showed significantly lower serum levels of IL-1β and IL-6 compared with the oral sinomenine group (both P < 0.05) . Conclusion:Sinomenine solution could obviously alleviate the severity of skin lesions in AD-like mouse models, likely by down-regulating the expression of IL-1β, IL-6 and IgE, inhibiting the MAPK/NF-κB signaling pathway, and thus reducing the degree of inflammation.

Sedentary bad habits and unhealthy diets in modern lifestyles have led to an upward trend in the incidence of obesity, and a series of diseases related to obesity have also gradually received attention. Multiple sclerosis is a chronic inflammatory disease of the central nervous system, and obesity has a common inflammatory component with most chronic diseases. Therefore, this paper reviews the research progress on the relationship between obesity and multiple sclerosis in order to better understand the role of obesity in the management of multiple sclerosis.
