Objective:To assess the prevalence and type of tissue prolapse (TP) occurring after endovascular treatment (ET), investigate the association between TP types and plaque morphological characteristics before ET, and observe in-stent neointimal hyperplasia (NIH) using optical coherence tomography (OCT).Methods:Patients who underwent carotid artery stenting and received pre- and post-ET OCT assessment at Jinling Hospital between July 2018 and December 2019 were collected. Baseline plaque characteristics and TP features were evaluated using OCT. The TPs were classified into two categories: smooth TP (STP) and irregular and/or high attenuated TP (I/HTP). The association between I/HTP and plaque characteristics was analyzed, while NIH feature was also summarized.Results:A total of 29 patients were included in the study, of whom 23 patients (79.3%) presented with TP. Among these 23 patients, 9 were classified as I/HTP and 14 were classified as STP. Compared with STP, I/HTP was more commonly observed in lipid-rich plaques (7/9 vs 2/14, P=0.007), and lesions with cap rupture (7/9 vs 4/14, P=0.036). Additionally, the longitudinal length of TP appeared to be longer in cases with I/HTP compared to those with STP [3.0 (1.5, 4.6) mm vs 1.1 (0.7, 3.2) mm, Z=1.294, P=0.201]. Six patients underwent OCT follow-up for a mean duration of 6.7 months, of whom 3 patients with I/HTP showed severe heterogeneous NIH (50.1%-61.8%), while 1 patient with STP and 2 patients without TP only demonstrated mild NIH. Conclusions:The study observed that I/HTP was commonly found in plaques with larger lipid core and/or cap rupture, and suggested a potential relationship between I/HTP and NIH. These preliminary findings obtained from a limited sample should be verified by prospective large-scale studies.

Objective:To analyze long-term prognosis and influencing factors of recurrence in vocal fold leukoplakia treated by endoscopic cordectomy with CO 2 laser. Methods:A retrospective review was conducted on 599 patients with vocal fold leukoplakia [566 males and 33 females, aged 17-84 years (median age 55 years)], undergoing endoscopic cordectomy by CO 2 laser under general anesthesia at the Department of Otorhinolaryngology Head and Neck Surgery of Beijing Tongren Hospital, Capital Medical University, from January 2000 to December 2023. The study analyzed the clinical features, pathological grade, surgical methods, postoperative voice function, recurrence, malignant changes and analyzed the long-term efficacy and and its influencing factors. The patients were followed up for a duration of 6-249 months postoperatively, with a median follow-up time of 48 months. SPSS 20.0 software was used for statistical analysis. Results:Among the 599 patients, the histopathological grades included simple squamous cell hyperplasia in ( n=264, 44.08%), mild dysplasia ( n=96, 16.03%), moderate dysplasia ( n=74, 12.35%), severe dysplasia( n=43, 7.81%), carcinoma in situ( n=35, 5.84%), and carcinoma in situ with microinvasion( n=87, 14.52%). The 3-year and 5-year overall recurrence rates were 12.91% and 16.00%, respectively. In patients with precancerous lesion, 3.91% of recurrences presented with an upgraded pathologic grade and 2.34% evolved into carcinoma. The risk of recurrence was higher in lesions involving the anterior commissure, larger lesions, significant reduction/absence of mucosal waves, neovascularization/suspected neovascularization, and pathology of dysplasia/carcinoma in situ/carcinoma in situ with microinvasion( F=44.76,21.54,11.55,8.78,23.20,respectively, P<0.05). Additionally, patients with recurrent disease exhibited higher reflux symptom index scores compared to those without recurrence. Exophytic lesion characteristics and the inability to cease smoking postoperatively were identified as independent risk factors for recurrence with an upgraded pathological grade, with odds ratios of 8.675 and 11.380 times greater than those with non-exophytic lesions and successful smoking cessation, respectively. At the 6-months postoperative assessment, patients who underwent subepithelial cordectomy (typeⅠ) demonstrated a statistically significant increase in fundamental frequency ( t=-3.38, P<0.05), and while other voice acoustic parameters were not significantly different.Conversely, those who underwent transmuscular cordectomy (TypeⅢ) exhibited significant alterations in multiple voice acoustic parameters when compared to preoperative values ( P<0.05). Furthermore, postoperative vocal fold adhesions developed in 84 patients with 13 of these individuals requiring surgical intervention for adhesion release. Conclusions:Lesions involving the anterior commissure, larger lesions, pathology of dysplasia/carcinoma in situ/carcinoma in situ with microinfiltration, significant reduction/absence of vocal fold mucosal waves, and neovascularization visible under NBI are indicative of an increased risk of recurrence, whereas exophytic lesions and the inability to cease smoking postoperatively significantly increase the risk of recurrence with elevated pathologic grade. Recovery of postoperative voice quality is procedure-dependent, underscoring the importance of surgical approach selection in the management of vocal fold leukoplakia.

OBJECTIVE To establish the UHPLC fingerprint of Miao Medicine Ficus tikoua Bur., study its spectrum-effect relationship with antioxidant activity, and screen the antioxidant active components. METHODS UHPLC was used to establish the fingerprint of Ficus tikoua Bur.. Evaluation System for Similarity of Chromatographic Fingerprint of Chinese Herbal Medicine (Version 2012) was used to evaluate the similarity and identify the common peaks. SPSS 16.0 and SIMCA 14.1 software were used for hierarchical cluster analysis(HCA) and principal component analysis(PCA). The 1,1-diphenyl-2-picrylhydrazyl(DPPH) free radical scavenging method, 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt(ABTS) free radical scavenging method and total antioxidant capacity method were used to evaluate the antioxidant activity of 16 batches of ethanol extracts from Ficus tikoua Bur. Three methods including grey relational analysis(GRA), bivariate correlation analysis and partial least squares regression(PLSR) were used to study the spectrum-effect relationship. RESULTS The UHPLC fingerprints of 16 batches of Ficus tikoua Bur. were established and 13 common peaks were identified. The similarities were 0.613−0.996. At the same time, it was identified that peak 9 was rutin, peak 10 was isoquercetin, and peak 12 was narcissin. The results of HCA showed that the samples were clustered into two categories, which was consistent with the PCA results. Sixteen batches of Ficus tikoua Bur. had different degrees of antioxidant activity. The results of GRA showed that the correlation between 13 common peaks and antioxidant activity was >0.8, and all of them had high correlation. The results of bivariate correlation analysis and PLSR analysis showed that the correlation coefficient and regression coefficient of peak 5, peak 9(rutin), peak 10(isoquercetin), peak 11 and peak 12(narcissin) were positively correlated with antioxidant activity, and the contribution rate was larger(variable importance in projection>1), which were the main active components of antioxidant activity. CONCLUSION All the 16 batches of Ficus tikoua Bur. have good antioxidant activity, and its antioxidant effect is the result of the synergistic action of the internal antioxidant component group. The components corresponding to the common peaks 5, 9, 10, 11, 12 are closely related to their antioxidant activity, revealing the pharmacodynamic material basis of the antioxidant activity of Ficus tikoua Bur.

OBJECTIVE To screen potential adverse drug event （ADE） signals for the treatment of multiple sclerosis （MS） with ofatumumab， and to provide reference for the safe use of drugs in clinical practice. METHODS Using “ofatumumab” and the trade name “Kesimpta” as the search keywords， adverse event （AE） reports related to ofatumumab included in FDA Adverse Event Reporting System database from January 2009 to December 2023 were screened， and their reason contained the “multiple sclerosis”； ADE signal mining and analysis were conducted by reporting odds ratio method and proportional reporting ratio method. RESULTS A total of 21 759 eligible AE reports were selected， involving 62 449 AE cases； 27 system organ classes included general diseases and various reactions at the site of administration （15 021 cases）， neurological diseases （9 668 cases）， infectious and invasive diseases （5 967 cases）， injury， poisoning and surgical complications （4 952 cases）， musculoskeletal and connective tissue disorders （4 647 cases）. A total of 21 759 AE reports correspond to 606 ADE signals， including 234 ADE positive signals. A total of 107 ADE positive signals were not included in drug instruction of ofatumumab， including flu-like diseases， nasopharyngitis， cough， urinary tract infection， sore throat， insomnia， runny nose， anemia， hair loss， atrial fibrillation， and thrombocytopenia， etc. CONCLUSIONS In the process of using ofatumumab for MS， sufficient attention should be paid to ADE included in drug instructions. The ADE with strong signal strength screened in this study should also be paid special attention to， such as flu-like diseases， hemocytopenia， temperature intolerance， optic neuritis， and moyamoya disease. The increased risk of infection， cardiovascular disease， and potential damage to the respiratory and spiritual systems caused by ofatumumab can not be ignored.

ObjectiveTo investigate the effects of Huashi Runzao prescription （HRP） on the histopathological injury and function of submandibular gland in naive non-obese diabetic （NOD/Ltj） mouse model of Sjögren's syndrome （SS） and its regulatory effect on aquaporin 5 （AQP5） expression in submandibular gland cells. MethodThe SS model was induced in NOD/Ltj mice. The NOD/Ltj female mice aged nine weeks were selected and randomly assigned into model group，HRP group （7.15 g·kg^-1·d^-1），and hydroxychloroquine （HCQ） group （1.30 g·kg^-1·d^-1）， and female BALB/c mice in the same age were selected and assigned into the normal group， with six mice in each group. Drug intervention lasted eight weeks. The water consumption and salivary flow rate （SFR） of each group were recorded. The pathological staining results of the submandibular gland of mice in each group were observed and scored. AQP5 expression was determined by immunohistochemistry （IHC） and Western blot. ResultCompared with the normal group， the model group showed increased water consumption （P<0.05） and reduced SFR （P<0.05）. Compared with the model group， the HRP group showed decreased water consumption （P<0.05） and increased SFR （P<0.05）， and the HCQ group showed increased SFR （P<0.05）. In terms of histopathological results of the submandibular gland，compared with the normal group，the model group showed increased pathological score， number of lymphocyte infiltration foci，and percentage of lymphatic infiltration area （P<0.05）. Compared with the model group， the HRP group showed reduced pathological scores and number of lymphocyte infiltration foci （P<0.05）， and the HRP group and the HCQ group showed reduced percentage of lymphatic infiltration area（P<0.05）. The results of IHC and Western blot showed that compared with the normal group，the model group showed down-regulated expression level of AQP5 protein （P<0.05）， and compared with the model group and the HCQ group，the HRP group showed up-regulated expression level of AQP5 protein （P<0.05）. ConclusionHRP can improve the secretion function of submandibular gland acinous cells and glandular structure injury in SS model mice， and its mechanism may be related to the up-regulation of AQP5 protein expression level in submandibular gland cells.

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 （P_trend<0.05）. In addition， the proportion of patients with phlegm-dampness syndrome decreased and that with Qi deficiency syndrome increased over time （P_trend<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.

Objective:To construct the "Internet +" peripherally inserted central catheter (PICC) home nursing service quality evaluation index system, so as to provide objective basis for standardizing the "Internet +" PICC home nursing service quality evaluation.Methods:Based on the three-dimensional quality structure model of "structure-process-outcome", combined with literature research, semi-structured interviews, group discussions and Delphi method, 20 experts who were engaged in intravenous therapy nursing and had management or practical experience in "Internet + nursing services" were selected for two rounds of consultation to determine the "Internet?+" PICC home nursing service quality evaluation index system. The positive coefficient of experts was expressed by the effective response rate of the questionnaire and the rate of expert opinion submission. The degree of expert authority was expressed by the expert authority coefficient. The coordination degree of expert opinions was represented by the Kendall harmony coefficient. The concentration degree of expert opinions was usually expressed in terms of the importance assigned to the indicator, the coefficient of variation, and the full score rate (%) .Results:The effective response rates of the two rounds of consultation questionnaires were all 100%, with expert authority coefficients of 0.793 and 0.848 respectively. The Kendall coordination coefficients of expert opinions were 0.202-0.216 and 0.222-0.270 respectively ( P<0.05). After the second round of expert consultation, the mean importance assigned to all indicators was greater than 4.0, the coefficient of variation was less than 0.2, and the full score rate was greater than 20%. The final "Internet +"PICC home nursing service quality evaluation index system included 3 first-level indicators, 12 second-level indicators and 64 third-level indicators. Conclusions:The "Internet + " PICC home nursing service quality evaluation index system constructed is scientific, reliable and practical, and reflects the specialty characteristics. It can effectively evaluate the "Internet + " PICC home nursing service quality and provide guidance for continuous improvement.
