ObjectiveTo explore the clinical efficacy of Juanbitang hot compress pack combined with intensive rehabilitation training in stroke patients with hemiplegia. MethodsA total of 80 stroke patients with hemiplegia were selected and assigned into a control group （40 cases） and an observation group （40 cases） according to the random number table method. The control group received conventional rehabilitation training and nursing intervention，while the observation group was additionally treated with Juanbitang hot compress pack. The two groups were compared in terms of the neurological function （national institute of health stroke scale score，NIHSS score），muscle strength，motor function （fugl-meyer assessment scale score，FMA score），daily living activity （modified barthel index，MBI），balance ability （berg balance scale score，BBS score），trunk control ability （Sheikh Trunk Control Test score，Sheikh TCT score），and homocysteine （Hcy） level before and after treatment. ResultsAfter treatment，the observation group had lower NIHSS score and Hcy level than the control group （P<0.05）. The total response rate of the observation group （97.50%） was higher than that of the control group （77.50%）. The scores of upper limb and lower limb FMA，MBI，BBS，and Sheikh TCT in the observation group were all higher than those in the control group （P<0.05）. ConclusionThe application of Juanbitang hot compress pack combined with rehabilitation training can effectively improve the neurological function，muscle strength，motor function，daily living ability，balance ability，and trunk control ability and reduce the Hcy level in stroke patients with hemiplegia，demonstrating enhanced clinical efficacy.

Cemental tear is a rare and indetectable condition unless obvious clinical signs present with the involvement of surrounding periodontal and periapical tissues. Due to its clinical manifestations similar to common dental issues, such as vertical root fracture, primary endodontic diseases, and periodontal diseases, as well as the low awareness of cemental tear for clinicians, misdiagnosis often occurs. The critical principle for cemental tear treatment is to remove torn fragments, and overlooking fragments leads to futile therapy, which could deteriorate the conditions of the affected teeth. Therefore, accurate diagnosis and subsequent appropriate interventions are vital for managing cemental tear. Novel diagnostic tools, including cone-beam computed tomography (CBCT), microscopes, and enamel matrix derivatives, have improved early detection and management, enhancing tooth retention. The implementation of standardized diagnostic criteria and treatment protocols, combined with improved clinical awareness among dental professionals, serves to mitigate risks of diagnostic errors and suboptimal therapeutic interventions. This expert consensus reviewed the epidemiology, pathogenesis, potential predisposing factors, clinical manifestations, diagnosis, differential diagnosis, treatment, and prognosis of cemental tear, aiming to provide a clinical guideline and facilitate clinicians to have a better understanding of cemental tear.

Objective: To examine the mediating effect of resilience on AIDS-related stress and patient-reported outcome among elderly cases with HIV/AIDS, so as to provide the basis for promoting mental health and improving health outcomes of this population. Methods: From June to July 2024, elderly cases with HIV/AIDS receiving treatment in the infectious diseases department of a tertiary-level hospital in Sichuan Province and undergoing follow-up management at 12 community health service centers in Wuhou District, Chengdu City, Sichuan Province, were selected as study participants using convenience sampling method. Data on demographic information, duration since confirmed diagnosis and the most recent CD4+T lymphocyte count were collected through questionnaire surveys. The Chinese versions of the HIV/AIDS Stress Scale, the Chinese versions of the 10-item Connor-Davidson Resilience Scale, and the Patient-Reported Outcome Scale for Elderly HIV/AIDS Patients were used to assess AIDS-related stress, resilience, and patient-reported outcome, respectively. Structural equation modeling was performed using Mplus 8.3 software to analyze the mediating effect of resilience on AIDS-related stress and patient-reported outcome. The Bootstrap method was employed to test the significance of the mediating effect. Results: A total of 424 elderly HIV/AIDS cases were included, with a mean age of (62.04±8.73) years. Among them, 315 (74.29%) were males and 109 (25.71%) were females. The median scores were 23.00 (interquartile range, 11.00) points for AIDS-related stress, 30.00 (interquartile range, 7.00) points for resilience, and 363.45 (interquartile range, 53.03) points for the total score of patient-reported outcome. Resultsof the mediation effect analysis revealed that AIDS-related stress had a direct negative effect on patient-reported outcome (β=-0.608, 95%CI: -0.742 to -0.465). It also exerted an indirect negative effect on patient-reported outcome through the mediating role of resilience (β=-0.258, 95%CI: -0.364 to -0.158), with the mediating effect accounting for 29.79% of the total effect. Conclusion AIDS-related stress among elderly cases with HIV/AIDS can directly or indirectly negatively affect patient-reported outcome through resilience.

Objective : To investigate the effects of sinapine on lung tissue inflammation and mucus hypersecretion in asthmatic mice. Methods: Eight-week-old female C57BL/6J mice were randomly divided into Control group, ovalbumin(OVA) group, Sinapine group, and Sinapine+OVA group. The asthmatic mice model were established by intraperitoneal injection of OVA combined with aluminum hydroxide [Al(OH)3] suspension and OVA nasal stimulation. One hour before OVA nasal stimulation, the mice in Sinapine+OVA group and Sinapine group were intraperitoneally injected with sinapine solution, and the mice in OVA group and Control group were treated with the same dose of 0.9% sodium chloride solution. 24 hours after the last OVA stimulation, the inflammation of lung tissue of mice were observed by HE staining; the mucus secretion were evaluated by PAS staining; the mRNA expression levels of Interleukin-4(IL-4), Interleukin-5(IL-5), Interleukin-13(IL-13), tumor necrosis factor-alpha(TNF-α), Mucin 5ac(Muc5ac), and the mRNA of the key genes of Notch pathway such as Notch receptor 1(Notch1), Notch receptor 2(Notch2), Notch receptor 3(Notch3), and hes family bHLH transcription factor 1(Hes1) in lung tissues were detected by real-time fluorescent quantitative PCR(RT-qPCR); the expression levels of Notch1, Notch2, Notch3 and Hes1 proteins were determined by Western blot. Results : Compared with Control group, the inflammation score and PAS score of lung tissues of mice in OVA group increased(P<0.001); the mRNA expression levels of IL-4, IL-5, IL-13, TNF-α, and Muc5ac of mice in OVA group were enhanced(P<0.05); the mRNA and protein expression levels of Notch2, Notch3, and Hes1 of mice in OVA group significantly increased(P<0.001), while there was no significant difference in the mRNA and protein expression levels of Notch1. Compared with OVA group, the inflammation score and PAS score of lung tissues of mice in Sinapine+OVA group decreased(P<0.001); the mRNA expression levels of IL-4, IL-5, IL-13, TNF-α, and Muc5ac of mice in Sinapine+OVA group were reduced(P<0.05); the mRNA and protein expression levels of Notch2, Notch3, and Hes1 of mice in Sinapine+OVA group were downregulated(P<0.05), while there was no significant difference in the mRNA and protein expression levels of Notch1. Conclusion Sinapine can alleviate the lung tissue inflammation and mucus hypersecretion in asthmatic mice, and its mechanism may be related to the inhibition of Notch2/Notch3-Hes1 signal pathway.

Objective To investigate the mechanism of autophagy induced by House dust mites(HDM)on airway epithelial tight junction through β-catenin-Snail signaling pathway.Methods Human bronchial epithelial cells(16HBE)were stimulated with HDM at different time points(0,3,6,12,24,48 h)and different concen-trations(0,40,100,200 μg/mL)to screen the appropriate stimulation concentration and stimulation time.16HBE cells were treated with oxidative stress inhibitor N-acetylcysteine(NAC),autophagy inhibitor 3-methylad-enine(3-MA),HDM,and their combinations.Cells were transfected with mCherry-EGFP-LC3B,Beclin-1-siRNA,and ATG14-siRNA lentivirus and then stimulated with NAC and HDM.Immunofluorescence was used to detect the expression levels of autophagy-related protein LC3B,tight junction-related proteins Occludin,and ZO-1 in airway epithelial cells.The level of reactive oxygen species(ROS)was detected by using DCFH-DA in each group.The protein expression levels of Occludin,ZO-1,LC3B,Beclin-1,ATG5,ATG14,P62,Snail,β-catenin and p-β-catenin were detected by Western blot method.Results Immunofluorescence results showed that compared with the control group,200 μg/mL HDM stimulation induced cellular autophagy,increased the expression level of LC3B protein,and promoted the level of ROS,all with statistical significances(all P<0.05).Compared with the HDM group,the HDM+3-MA,HDM+ATG14-si,and HDM+Beclin-1-si groupsall showed significantincreases in the expression levels of tight junction-related proteins Occludin and ZO-1(P<0.05).The HDM+NAC group demonstrated significant decreases both in the level of ROS andin the expression level of LC3B protein.Western blot results revealed that compared with HDM,3-MA and autophagy protein low-expression beads(Beclin-1-si,ATG14-si)attenuated HDM-induced cellular autophagy(P<0.05),inhibited HDM-induced upregulation of Snail and p-β-catenin expression,and improved HDM-induced decreases in Occludin and ZO-1(P<0.05).Moreover,compared with the HDM group,the NAC+HDM group exhibited significant decreases both in the conversion of LC3BⅠ to LC3BⅡ(P<0.001)in the protein levels of Snail,p-β-catenin,Beclin-1 and ATG14(P<0.01),but significant increases in the protein levels of Occludin and ZO-1(P<0.05).Conclusion HDM affects the tight connections between airway epithelial cells by inducing autophagy,which may be attributed to the β-catenin-Snail signaling pathway.

Purpose To investigate the clinical,imaging,and pathological features of Kikuchi-Fujimoto disease(KFD).Methods A retrospective analysis was conducted on 123 pathologically confirmed KFD cases.Clinical and imaging data were collected,and histopathological features were evaluated using HE staining,immunohistochemistry,in situ hybridization for EBER,and molecular analyses(TCR/Ig gene rearrangements by PCR with capillary electro-phoresis).Results Among the 123 patients,the male-to-female ratio was 1∶2,with a median age of 30 years.All patients presented with lymphadenopathy.Among 30 hospitalized patients,63.3％(19/30)had fever,and 23.3％(7/30)had concurrent autoimmune diseases.Of the 12 patients who underwent PET-CT,91.7％(11/12)were sus-pected of malignancy,prompting biopsy recommendations.Among 47 consultation cases,27.7％(13/47)were ini-tially misdiagnosed as lymphoma.Histopathological examination revealed proliferative,necrotic,and xanthomatous phases,which coexisted or occurred independently.The proliferative phase was characterized by atypical lymphocytes and histiocytes,the necrotic phase by abundant eosinophilic fibrin deposits and nuclear debris,and the xanthomatous phase by clusters of foam-like histiocytes.Immunohistochemically analyses revealed that atypical lymphocytes were neg-ative for CD20,CD4,and CD56 but positive for CD3,CD8,TIA1,Granzyme B,and Perforin.Histiocytes expressed CD68,CD163,and MPO,while CD123-positive plasmacytoid dendritic cells were predominantly located around the le-sions and blood vessels.EBER was positive in individual cells in 4 cases.TCR gene rearrangement was positive in 2 cases and suspected positive in 3 cases,while Ig rearrangement was positive and suspected positive in 1 case each.Conclusion KFD exhibits clinical,imaging,and pathological features that can mimic lymphoma,highlighting the im-portance of accurate diagnosis to avoid misdiagnosis and inappropriate treatment.

AIM:To evaluate the effect of differ-ent frequencies 0.01%atropine eye drops on the ocular surface in adolescent myopia control.METH-ODS:A total of 84 adolescent patients with myopia were recruited for this study.They were randomly assigned to receive 0.01%atropine eye drops at dif-ferent frequencies(morning group,evening group,morning and evening group).During the treatment period,ocular and systemic adverse reactions were observed,spherical equivalent refraction(SER)and axial length(AX)were examined.Additionally,ocu-lar surface disease index(OSDI)questionnaire was obtained,tear meniscus height(TMH),non-inva-sive first tear film break-up time(NifBUT),non-inva-sive average tear film break-up time(NiaBUT),and meibomian gland atrophy score(MaS)were mea-sured by Keratograph 5M.RESULTS:During the 6-month treatment with 0.01%atropine eye drops,all adverse reaction symptoms were relatively mild and infrequent.Only one case of systemic reaction was reported,with temporary xerostomia.Six pa-tients reported discomfort such as ocular itching and dryness.The ocular reactions of photophobia and blurred near vision were slightly more com-mon in the morning and combined morning-eve-ning groups compared to the evening group,but there were no significant differences among the three groups(P>0.05).Compared to baseline,there were significant differences in SER and AX among the three groups after six months of treatment(P<0.05).Compared to baseline,no significant differ-ences were observed in the Morning group after six months of treatment in terms of OSDI score(P=0.656),TMH value(P=0.362),NifBUT(P=0.510),Ni-aBUT(P=0.700),and MaS(P=0.846).Similarly,no significant changes were found in the Evening group regarding OSDI score(P=0.429),TMH value(P=0.462),NifBUT(P=0.462),NiaBUT(P=0.598),and MaS(P=0.351).Additionally,in the Morning and evening group,no significant changes were de-tected in OSDI score(P=0.457),TMH value(P=0.748),NifBUT(P=0.197),NiaBUT(P=0.070),and MaS(P=0.802)after six months of treatment.CON-CLUSION:After six months of using 0.01%atropine eye drops with different frequencies in adolescent myopia control,there was no significant impact on the ocular surface.

Purpose To investigate the clinicopathological features and prognosis of adult large B-cell lymphoma with IRF4 rearrangement(LBCL-IRF4r).Methods Clinical data of 63 adult LBCL-IRF4r cases were collected.The EnVision two-step method was employed for immunohistochemical staining,and fluorescence in situ hybridization was used to detect rearrangements or deletions of the IRF4,BCL2,MYC,BCL6,and TP53 genes.The relationship be-tween clinicopathological features and prognosis was analyzed and compared with data from 132 adult non-specified dif-fuse large B-cell lymphoma(DLBCL)cases.Results Among the 63 adult LBCL-IRF4r patients,the male to female ratio was 1.1∶1,with a median age of 54.0 years(range 20-84 years),and 14 cases(22.2％)were＜40 years old,24 cases(38.1％)were between 40 and 60 years old,and 25 cases(39.7％)were＞60 years old.18 cases(28.6％)were involved in Waldeyer's ring,along with 8 cases(12.7％)in cervical lymph nodes,7 cases(11.1％)in other lymph nodes and lymphatic organs,13 cases(20.6％)in stomach,4 cases(6.4％)in intestine,and 13 cases(20.6％)in other extranodal sites.63 cases showed IRF4 rearrangements,with no BCL2 and MYC translocations(0/58),30.9％(17/55)had BCL6 translocations,and 16.3％(8/49)had TP53 deletions.59 pa-tients were followed up for a median of 28 months(range 1-65 months).48 patients(81.4％)achieved complete re-sponse,10 patients(16.9％)experienced disease progression or relapse,and 3 patients(5.1％)died.Univariate a-nalysis showed that lactate dehydrogenase level,Ann Arbor stage,international prognostic index(IPI)score,growth pattern,Hans classification,and double expression of BCL2 and C-MYC were significantly associated with progression-free survival.Age,Ann Arbor stage,and IPI score were significantly associated with overall survival.Multivariate Cox regression analysis showed that double expression of BCL2 and C-MYC was an independent prognostic factor for pro-gression-free survival.Adult LBCL-IRF4r had significantly higher complete response rate and progression-free survival than adult DLBCL.Conclusion LBCL-IRF4r occurs in adults of all age groups,commonly affecting Waldeyer's ring,cervical lymph nodes,and gastrointestinal tract,and has a favorable clinical prognosis.

Objective:To evaluate the efficacy and safety of nebulized inhalation of recombinant human interferon (IFN) α1b injection in the treatment of respiratory syncytial virus (RSV) associated lower respiratory tract infections (pneumonia and bronchiolitis) in children.Methods:A randomized, double-blind, parallel, placebo-controlled add-on design was used.Children with pneumonia or bronchiolitis aged 2 months to 5 years who tested positive for RSV antigen within 72 hours of onset from 30 clinical trial sites including Beijing Children′s Hospital, Capital Medical University between February 2021 and December 2022 were included in this study and randomly divided into 2 groups at a ratio of 1∶1 based on a stratified-block method.Both groups received basic treatments such as cough control, asthma relieving, expectorant treatment, fever reduction, oxygen therapy, etc.The experimental group received additional nebulized inhalation of IFN α1b injection at a dose of 2.0 μg/(kg·time), twice a day.The control group received nebulized inhalation of placebo twice a day.Clinical efficacy was evaluated based on indicators such as the duration of clinical symptoms and signs, and the Kaplan-Meier method was used to calculate the median and 95% CI of the duration of clinical symptoms and signs.The Log-rank test was used to compared data between groups.Safety was assessed through the incidence of adverse reactions and laboratory tests, and the Chi-square test was used to analyze the difference between groups. Results:There were 123 children in the experimental group and 122 children in the control group.The median durations of all the 5 clinical symptoms and signs [including shortness of breath, wheezing, dyspnea (visible retractions), decreased transcutaneous oxygen saturation, and abnormal mental state] in the experimental group after treatment were slightly shortened than those in the control group [2.7 d(95% CI: 1.9-3.0 d)] vs.[2.9 d(95% CI: 2.6-3.6 d), P=0.027].The improvement in dyspnea (retractions) was especially pronounced in the experimental group, with a relief rate of 50.0% (0, 100%) on the first day of administration[compared with 0 (0, 50.0%) in the control group ( Z=2.002, P=0.025)].The median duration of dyspnea in the experimental group was nearly 1 day shorter than that in the control group [1.0 d(95% CI: 0.7-1.7 d) vs.1.8 d(95% CI: 1.0-2.5 d), P=0.046].There were no significant difference in hospital stay [6.0(5.0, 8.0) d vs.6.5(5.0, 8.0) d, Z=0.675, P=0.500], oxygen therapy duration [32.0(14.0, 96.3) h vs.39.0 (24.0, 83.2) h, Z=0.094, P=0.925], the recovery rate from clinical symptoms during treatment [(105/106, 99.1%) vs.(96/101, 95.0%)], and recurrence rate [(0/106, 0) vs.(2/101, 2.0%)] between the 2 groups (all P>0.05).However, the above-mentioned four indicators in the experimental group showed a trend of clinical benefits.The quantitative virus detection results showed that the RSV viral load in both groups decreased after treatment compared to before treatment.After 2 days of treatment, the decline rate of RSV viral load from the baseline was 0.90 lg copies/(mL·d) in the experimental group and 0.25 lg copies/(mL·d)in the control group, with a statistically significant difference ( P<0.05).Furthermore, there was no statistically significant difference in the incidence of adverse reactions between the 2 groups ( P>0.05).Importantly, no drug-related serious adverse reactions occurred in both groups. Conclusions:The nebulized inhalation therapy of IFN α1b demonstrates efficacy and safety in treating pediatric RSV associated lower respiratory tract infections.It particularly offers outstanding clinical therapeutic value for severe children.
