Objective:To study a new type of impulse neuron model and its network, describe its modeling method, and verify its performance by computer simulation.Methods:Based on full consideration of biological adaptability (activation potential threshold and refractory period switch) and its dynamic regulation mechanism for the generation and transmission of spike discharge pulses, a post-potential multi-channel filter was introduced in the new impulse neuron model. The filter can realize the dynamic adjustment of output current and neuron synaptic strength. An error back-propagation (BP) learning algorithm based on adaptive least mean square (LMS) was proposed, and applied to the regulation of spike discharge neural networks.Results:Under spontaneous noise, the pulsation interval signal histogram of the new impulse neuron model satisfies Poisson distribution. Through the simple connection of two new pulsed neurons, a variety of complex spike discharge patterns can be formed. The new impulse neuron model has the characteristics of spontaneous intrinsic noise, can form complex periodic spike discharge patterns. For input noise control, the refractory period and threshold potential adaptability parameters of the new impulse neuron model has good stability. The linear relationship between the stimulation current and the frequency of the spike discharge pulse is good.Conclusions:The proposed new model can generate multiple modes of oscillation and coherent oscillation under the condition of spontaneous noise, which is very similar to biological neurons and can realize complex noise processing. The multi-channel post-synaptic potential filters with different frequency bands can make some post-synaptic potential signals become smooth. The proposed BP learning algorithm based on adaptive LMS can overcome the problem that the error-driven learning algorithm cannot be applied due to the transient characteristics of the spike discharge signal.

ObjectiveTo observe the efficacy and safety of Huashi Runzao prescription for patients with primary Sjögren's syndrome (pSS) of combined dryness and dampness pattern. MethodA total of 105 eligible patients were randomized into the experimental group (65 cases) and control group (40 cases), and they were respectively treated with Huashi Runzao prescription and hydroxychloroquine for 12 weeks. Visual Analogue Scale (VAS) was employed to assess the symptoms. The symptoms of dryness, fatigue, and pain, European League Against Rheumatism (EULAR) Sjögren's Syndrome Patient Reported Index (ESSPRI), EULAR Sjögren's syndrome disease activity index (ESSDAI), and immune inflammatory indicators before and after treatment were compared between the two groups, and adverse reactions were observed. ResultAfter treatment, the ESSPRI score was lower than that before treatment in the experimental groups (P<0.01) and was lower in the experimental group than in the control group (P<0.05). The VAS scores of dry mouth, dry eyes, overall dryness, fatigue, and pain in the experimental group decreased compared with those before treatment (P<0.01), and the experimental group had lower VAS scores of dry mouth and overall dryness than the control group (P<0.01). After treatment, the ESSDAI score of both groups decreased compared with that before treatment (P<0.05, P<0.01), but there was no significant difference between the groups. After treatment, the level of immunoglobulin M (IgM) decreased (P<0.01) and the level of complement C3 increased (P<0.01) in the experimental group, while the level of complement C3 decreased in the control group (P<0.05). There was no significant difference in the laboratory indexes between groups. During the treatment, stomachache occurred to one case in the experimental group, which was alleviated after the treatment, and no adverse reaction was observed in the control group. According to the chi-square test, the occurrence of adverse reactions was insignificantly different between the two groups. ConclusionHuashi Runzao prescription can alleviate the symptoms of dryness, fatigue, and pain, and reduce disease activity without associated side effects in pSS patients with combined dampness and dryness pattern.

ObjectiveTo explore the characteristics of tongue manifestations and traditional Chinese medicine (TCM) syndromes in patients with primary Sjogren's syndrome (pSS) of different time. MethodpSS patients who visited TCM Department of Rheumatism in China-Japan Friendship Hospital from December 2018 to October 2021 were included and grouped according to the disease courses (short<5 years, medium 5-10 years, long > 10 years). Chi-square test was used for comparison between three groups and Bonferroni method for multiple comparisons. In the pairwise comparison, P<0.017 indicated significant difference. Chi-square test was performed on the syndrome and specific tongue manifestations with inter-group differences to analyze the trend of tongue manifestations and TCM syndromes over time (interval: two years). ResultA total of 193 pSS patients were enrolled, with 85 (44.0%) of short disease course, 69 (35.8%) of medium disease course, and 39 (20.2%) of long disease course. The common tongue manifestations were crimson tongue, fissured tongue, thin tongue, lack of fluid, and dry coating, which showed no significant difference among the three groups. Higher proportion of patients with light red tongue was observed in the group with short disease course than in group with medium disease course (χ2=6.407, P<0.017). Higher proportions of patients with thick coating (χ2=6.784, P<0.017) and phlegm-dampness syndrome (χ2=11.545, P<0.017) and lower proportion of patients with Qi deficiency syndrome (χ2=12.706, P<0.017) were found in the group with short disease course than in the group with long disease course. Patients with medium (χ2=6.358, P<0.017) and long (χ2=8.279, P<0.017) disease course tended to have exfoliated coating compared with those with short disease course, and the proportion of patients with exfoliated coating rose and the proportion of patients with thick greasy coating decreased over time (Ptrend<0.05). In addition, the proportion of patients with phlegm-dampness syndrome decreased and that with Qi deficiency syndrome increased over time (Ptrend<0.05). ConclusionIn the early stage, patients with pSS often show both dryness and dampness, as manifested by the thick greasy coating and phlegm-dampness syndrome. In the medium and late stage, patients often have Qi-Yin deficiency, as evidenced by exfoliated coating and Qi deficiency. In the clinical practice, medicines should be prescribed based on tongue manifestations and TCM syndrome of patients.

ObjectiveTo analyze the clinical characteristics of geographic tongue in patients with primary Sjögren's syndrome (pSS). MethodPatients with pSS treated in the China-Japan Friendship Hospital from December 2018 to October 2021 were enrolled and divided into different groups according to the presence of geographic tongue or the severity. Phi correlation analysis,Chi-square test, and Mann-Whitney test were used to analyze the clinical characteristics of patients with geographic tongue. ResultA total of 182 pSS patients were included in this study,including 75 (41.2%) patients with geographic tongue and 107 (58.8%) without geographic tongue. Partial exfoliation was more common than total exfoliation, and the anterior part of the tongue was the most common exfoliation site. The number of patients with severe geographic tongue was more than those with mild-to-moderate geographic tongue. Compared with pSS patients without geographic tongue,those with geographic tongue were more common in fissured tongue (92.0%/41.1%,χ2=48.491,P<0.05),red or crimson tongue (48.0%/23.3%,χ2=12.009,P<0.05),Yin deficiency syndrome (100.0%/43.9%,χ2=62.739,P<0.05),and Qi deficiency syndrome (94.7%∶50.5%,χ2=40.046,P<0.05),less common in phlegm-dampness syndrome (33.3%/72.0%,χ2=26.709,P<0.05),and showed higher proportions in hyperglobulinemia (89.3%/65.4%,χ2=13.547,P<0.01),ANA ≥1∶160 (78.1%/57.3%,χ2=8.227,P<0.01),and positive RF (51.4%/36.5%,χ2=3.877,P<0.05). Compared with pSS patients with mild geographic tongue,pSS patients with moderate-to-severe geographic tongue had higher proportions in hyperglobulinemia (98.1%/68.2%,χ2=14.617,P<0.01),positive anti-CENP-B (26.0%/4.8%,χ2=4.214,P<0.05),and reduced complement 3 (26.4%/4.5%,χ2=4.647,P<0.05). The geographic tongue was positively associated with fissured tongue (φ=0.531),Yin deficiency syndrome (φ=0.587),and Qi deficiency syndrome (φ=0.469),negatively associated with phlegm-dampness syndrome (φ=-0.447),and weakly associated with tongue color (φ<0.4). There was no statistical difference in the disease activity index between patients with or without geographic tongue and severity. ConclusionMore than 40% of pSS patients had geographic tongue accompanied by fissured tongue. Geographic tongue is positively associated with Yin deficiency syndrome and Qi deficiency syndrome,and negatively associated with phlegm-dampness syndrome, indicating that treatment should be based on tonifying Qi and nourishing Yin. Compared with pSS patients without geographic tongue, those with geographic tongue may have higher positive rate of some immune indicators,which deserves further exploration.

ObjectiveTo summarize the characteristics of traditional Chinese medicine (TCM) syndrome in primary Sjögren's syndrome (pSS) patients with interstitial lung disease (ILD) and to explore associated factors. MethodA survey was conducted and pSS patients who were treated in TCM department of rheumatism at China-Japan Friendship Hospital from December 2018 to April 2022 were included. Tongue manifestations and syndromes of patients were recorded. pSS patients with ILD were classified into the pSS-ILD group and those without the ILD were included in the pSS-non-ILD group. The tongue manifestations, syndromes, and laboratory indexes were compared between the two groups, and logistic regression was used to explore the factors associated with pSS-ILD. ResultA total of 200 pSS patients were included, with 186 (93.0%) females, median age of 57 years, and median disease course of 60 months, of which 44 (22%) had pSS-ILD. In terms of tongue manifestations, pSS-ILD patients generally had dark/purple/stasis tongue, fissured tongue, and tongue with little fluid, thick coating, yellow coating, and greasy coating. The proportion patients with yellow coating was higher in pSS-ILD group than in the pSS-non-ILD group (χ2=4.799,P<0.05). In terms of syndrome, more than 40% of pSS-ILD patients had Qi deficiency, Yin deficiency, phlegm-dampness, Qi stagnation, and/or blood stasis syndrome. As for Yin deficiency, liver-kidney Yin deficiency syndrome ranked the first. For Qi deficiency, lung Qi deficiency syndrome was most commonly seen. The proportion of patients with lung Qi deficiency was higher in the pSS-ILD group than in the pSS-non-ILD group (χ2=18.667,P<0.01). As to laboratory indexes, compared with the pSS-non-ILD group, pSS-ILD group had high proportion of anti-SSA-positive patients (P<0.05) and high levels of C-reactive protein (CRP) (P<0.01), complement C3 (χ2=4.332,P<0.05), and complement C4 (P<0.05). Logistic regression analysis showed that pSS with ILD was positively associated with lung Qi deficiency [odds ratio (OR)=6.079, 95% confidence interval (CI) 2.585-14.298, P<0.01)] and yellow coating (OR=5.260, 95% CI 1.337-20.692, P<0.05) and negatively associated with low C4 (OR=0.199, 95% CI 0.070-0.564, P<0.01). ConclusionAbout 22% of pSS patients had ILD, and patients with pSS-ILD generally have Qi deficiency, Yin deficiency, phlegm-dampness, Qi stagnation, and/or blood stasis syndrome. Yellow coating, lung Qi deficiency and C4 level are factors associated with pSS combined with ILD.
