Objective To investigate the effect of berberine and its mechanism in delaying silica-induced lung injury via network pharmacology and molecular docking, followed by verification with animal experiments. Methods i) Targets of berberine and silicosis were obtained from multiple databases, and the common targets were identified. A protein-protein interaction network was constructed using the STRING database, and Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses were performed on the common targets via the DAVID database. Molecular docking was conducted using AutoDock software for validation. ii) Specific pathogen-free Wistar rats were randomly divided into five groups, with six rats in each group. Rats in the model group, pirfenidone group, and low- and high-dose berberine groups received a single non-exposure intratracheal instillation of 1.00 mL silica suspension at a mass concentration of 100 g/L, whereas rats in the control group received an equal volume of 0.9% sodium chloride solution. Rats in the pirfenidone group were administered with pirfenidone solution at a dose of 100 mg/kg body weight, and rats in the low- and high-dose berberine groups were administered with berberine solutions at doses of 100 and 200 mg/kg body weight, respectively. The remaining two groups received equal volumes of 0.9% sodium chloride solution. All treatments were administered by gavage once daily for 28 consecutive days from 24 hours after silica exposure. After intervention, rats in each group were sacrificed. Histopathological changes in lung tissues were observed, and the lung organ coefficient was detected. Serum malondialdehyde (MDA) was detected by colorimetry. Serum inflammatory cytokine were detected by enzyme-linked immunosorbent assay. The expression of fibrosis markers in lung tissues was detected by immunohistochemistry. The protein expression of phosphatidylinositol 3-kinase (PI3K), protein kinase B (AKT), and phosphorylated AKT (p-AKT) in lung tissues was determined by Western blot. Results i) Network pharmacology analysis identified 46 potential targets. The core targets included AKT1, tumor protein p53, caspase-3, matrix metalloproteinase-9, and albumin. GO enrichment analysis revealed that the targets related to the anti-fibrotic effect of berberine against silicosis were mainly enriched in biological processes including signal transduction, negative regulation of apoptosis, extracellular matrix degradation, and response to reactive oxygen species. KEGG enrichment analysis showed that berberine exerted anti-silicosis effects through multiple signaling pathways, such as the PI3K/AKT pathway, hypoxia-inducible factor-1 pathway, and advanced glycation end product (AGE)-receptor for AGE pathway. ii) Histopathological examination revealed that rats in the model group presented typical pulmonary fibrotic lesions. Pathological lung injury of rats was alleviated in all three intervention groups (pirfenidone group, low- and high-dose berberine group) compared with the model group. The improvement in the high-dose berberine group was superior to that in the low-dose berberine group and was comparable with that in the pirfenidone group. rats in the model group showed increased lung organ coefficient, serum MDA, interleukin-1β (IL-1β), and tumor necrosis factor-α (TNF-α) (all P<0.05), as well as increased expression of typeⅠcollagen (COLⅠ), α-smooth muscle actin (α-SMA) and PI3K, and p-AKT/AKT ratio in lung tissues (all P<0.05) when compared with the control group. The above indicators were lower in rats in both the low- and high-dose berberine groups than those in the model group (all P<0.05). Serum MDA, IL-1β, and TNF-α, as well as relative expression of COLⅠ and α-SMA in lung tissues, were lower in the high-dose berberine group than in the low-dose berberine group (all P<0.05). Conclusion Berberine may alleviate pulmonary inflammation and fibrosis in rats through regulation of the PI3K/AKT signaling pathway, thereby delaying the progression of silicosis.

As a global public health concern, parasitic diseases have been a great threat to human health for a long period of time. Following decades of integrated control efforts, the incidence of soil-transmitted and food-borne parasitic diseases has been remarkable reduced in most endemic foci of China, and is now low across the country. However, there are still multiple factors affecting the transmission of soil-transmitted and food-borne parasitic diseases, which pose multiple challenges to parasitic diseases surveillance in the new era. This article analyzed the current status and challenges of soil-transmitted and food-borne parasitic diseases surveillance in Jiangsu Province, a low-endemicity area, and proposed countermeasures to tackle the challenges, so as to provide insights into key parasitic diseases surveillance in the new era.

Antibody (Ab) humanization is critical to reduce immunogenicity and enhance efficacy in the preclinical phase of the development of therapeutic Abs originated from animal models. Computational suggestions have long been desired, but available tools focused on immunogenicity calculation of whole Ab sequences and sequence segments, missing the individual residue sites. This study introduces Site-specific Immunogenicity for Therapeutic Antibody (SITA), a novel computational framework that predicts B-cell immunogenicity score for not only the overall antibody, but also individual residues, based on a comprehensive set of amino acid descriptors characterizing physicochemical and spatial features for antibody structures. A transfer-learning-inspired framework was purposely adopted to overcome the scarcity of Ab-Ab structural complexes. On an independent testing dataset derived from 13 Ab-Ab structural complexes, SITA successfully predicted the epitope sites for Ab-Ab structures with a receiver operating characteristic (ROC)-area unver the ROC curve (AUC) of 0.85 and a precision-recall (PR)-AUC of 0.305 at the residue level. Furthermore, the SITA score can significantly distinguish immunogenicity levels of whole human Abs, therapeutic Abs and non-human-derived Abs. More importantly, analysis of an additional 25 therapeutic Abs revealed that over 70% of them were detected with decreased immunogenicity after modification compared to their parent variants. Among these, nearly 66% Abs successfully identified actual modification sites from the top five sites with the highest SITA scores, suggesting the ability of SITA scores for guide the humanization of antibody. Overall, these findings highlight the potential of SITA in optimizing immunogenicity assessments during the process of therapeutic antibody design.

Objective:To explore the screening value of platelet parameters from blood cell analysis for MYH9-related disorders(MYH9-RD).Methods:A cross-sectional study was conducted with 38 patients diagnosed with MYH9-RD at Shenzhen Children's Hospital from May 1, 2016, to August 31, 2024, including 24 males and 14 females; the median age was 11.5 (3.8, 35) years; categorized by gene mutation location into "head region" ( n=8 ) and "tail region" ( n=30); and by clinical manifestations into " isolated hematological manifestations" ( n=16) and "hematological manifestations with extra-hematological involvement"( n=22). The control groups included 39 cases of immune thrombocytopenia (ITP), 38 cases of acute lymphoblastic leukemia (ALL), and 40 healthy individuals. Platelet-related parameters were detected by hematology analyzer, and platelet counts and sizes were confirmed by manually counting and microscopic observation. Kruskal-Wallis test was used to compare platelet parameters between MYH9-RD and control groups. Receiver operating characteristic (ROC) curves were used to assess the diagnostic efficacy of platelet parameters for MYH9-RD. Results:In MYH9-RD patients the median value of mean platelet volume (MPV) was 13.4 (11.2, 14.7) fl, immature platelet fraction (IPF) was 52.7% (43.5%, 58.0%), platelet large cell ratio(PLCR) was 57.6 %(45.0%, 62.9%), and microscopic large platelet ratio (PLCR-M) was 30.0% (25.0%, 30.0%).And those values weresignificantly higher than in ITP, ALL, and healthy controls (all P<0.05). Patients with MYH9 gene "head region" mutations had a lower platelet count [24.5 (15.0, 47.5)×10 9/L]than those with "tail region" mutations [69.0 (49.5, 86.3) ×10 9/L]( Z=-3.493, P<0.001), but a higher IPF ( t=2.024, P=0.044).Patients with "extra-hematological involvement had a lower platelet count than those with "isolated hematological manifestations" ( t=-2.015, P=0.043). The optimal cutoff value for diagnosing MYH9-RD with IPF was 26.7%, with a sensitivity of 100% and specificity of 98.7%; the area under the curve was 0.999 (95% CI 0.995-1.000), which was superior toMPV, PLCR and PLCR-M parameters. Conclusion:IPF is superior to other platelet parameters sush as MPV,showing high diagnostic efficacy in distinguishing MYH9-RD from ITP and ALL. It can be used as a simple and effective indicator for early screening of MYH9-RD.

Objective:To investigate the disparities in breast cancer burden and changing epidemiological trends between China and the United States(US)from 1990 to 2021 and identify the key driving factors.Methods:The Global Burden of Disease database(1990-2021)was utilized to analyze breast cancer incidence,mortality,and disability adjusted life years(DALYs)in China and the US;we also assessed the as-sociations with risk factors(e.g.,obesity and smoking)through regression models and spatiotemporal analysis.Results:China's breast can-cer age-standardized incidence rate(ASIR)surged from 9.08/100,000 in 1990 to 19.36/100,000 in 2021,whereas the US ASIR declined from 44.37/100,000 to 37.49/100,000.Regarding the age-standardized mortality rate(ASMR),China saw a marginal reduction from 4.70/100,000 to 4.40/100,000,whereas the US experienced a significant decline from 13.03/100,000 to 9.28/100,000,narrowing the mortality gap from 2.8-fold to 2.1-fold.Key risk factors contributing to mortality and DALYs included smoking,exposure to secondhand smoke,low physical activity,high red meat and alcohol intake,elevated fasting blood glucose levels,and high body mass index.The rising cancer incidence in China is associated with the westernization of lifestyles and changes in fertility patterns,whereas the United States has achieved a dual de-cline in both incidence and mortality rates through widespread screening and control of hormone replacement therapy.Conclusions:Both the incidence and mortality rates of breast cancer in China rank among the highest globally,with incidence rates still increasing,indicating severe issues in prevention and control.In contrast,although the incidence rate in the US is higher than that in China,it shows a declining trend.To alleviate the growing burden of breast cancer,China must further enhance the intensity and coverage of breast cancer screening.

Depression is increasingly prevalent among adolescents and can profoundly impact their lives. However, the early detection of depression is often hindered by the time-consuming diagnostic process and the absence of objective biomarkers. In this study, we propose a novel approach for depression detection based on an affective brain-computer interface (aBCI) and the resting-state electroencephalogram (EEG). By fusing EEG features associated with both emotional and resting states, our method captures comprehensive depression-related information. The final depression detection model, derived through decision fusion with multiple independent models, further enhances detection efficacy. Our experiments involved 40 adolescents with depression and 40 matched controls. The proposed model achieved an accuracy of 86.54% on cross-validation and 88.20% on the independent test set, demonstrating the efficiency of multimodal fusion. In addition, further analysis revealed distinct brain activity patterns between the two groups across different modalities. These findings hold promise for new directions in depression detection and intervention.

Protrusive facial deformities, characterized by the forward displacement of the teeth and/or jaws beyond the normal range, affect a considerable portion of the population. The manifestations and morphological mechanisms of protrusive facial deformities are complex and diverse, requiring orthodontists to possess a high level of theoretical knowledge and practical experience in the relevant orthodontic field. To further optimize the correction of protrusive facial deformities, this consensus proposes that the morphological mechanisms and diagnosis of protrusive facial deformities should be analyzed and judged from multiple dimensions and factors to accurately formulate treatment plans. It emphasizes the use of orthodontic strategies, including jaw growth modification, tooth extraction or non-extraction for anterior teeth retraction, and maxillofacial vertical control. These strategies aim to reduce anterior teeth and lip protrusion, increase chin prominence, harmonize nasolabial and chin-lip relationships, and improve the facial profile of patients with protrusive facial deformities. For severe skeletal protrusive facial deformities, orthodontic-orthognathic combined treatment may be suggested. This consensus summarizes the theoretical knowledge and clinical experience of numerous renowned oral experts nationwide, offering reference strategies for the correction of protrusive facial deformities.

Objective To understand the current status of traditional Chinese medicine(TCM)systematic reviews/Meta-analysis over the past 10 years.Methods Cochrane Database of Systematic Reviews,PubMed,Web of Knowledge,CNKI,SinoMed,WanFang Data,VIP databases,as well as the Cochrane Register and PROSPERO registration platform were searched to collect TCM-related systematic reviews/Meta-analysis published between January 2015 and December 2024.Literature was screened,and standardization of institutions,countries,and journals was performed.Data cleaning was conducted,and trends in publication years,high-frequency diseases,journals,institutions,and highly cited papers were analyzed.Results A total of 11,174 papers were included,involving approximately 56,656 authors from 1,422 institutions across 44 countries,covering 1,300 journals and 1,070 diseases.The top five institutions in terms of publications were Beijing University of Chinese Medicine(954 papers),Guangzhou University of Chinese Medicine(928 papers),China Academy of Chinese Medical Sciences(537 papers),Tianjin University of Chinese Medicine(460 papers),and Chengdu University of Chinese Medicine(393 papers).Foreign institutions with the highest publication volumes were concentrated in South Korea,Iran,and Australia.The most frequently published Chinese journal was Zhongyi Clinical Research with 332 papers,while the most published English journal was Evidence-Based Complementary and Alternative Medicine with 311 papers.There were 282 single-author papers involving 271 authors,and the most cited paper was referenced 323 times,The three most frequently studied diseases were diabetes(267 papers,2.39％),angina pectoris(214 papers,1.92％),and osteoarthritis(210 papers,1.88％).Non-pharmacological interventions such as acupuncture(1,265 papers,11.32％),auricular therapy(101 papers,0.90％),and Tai Chi(98 papers,0.88％)were most frequently reported.In pharmacological interventions,studies on Tripterygium wilfordii tablets(76 papers,0.68％)and Danhong injection(54 papers,0.48％)were more common.Conclusion The systematic reviews/Meta-analysis method is widely used in the field of TCM,and the field continues to grow.Active academic teams,institutions,and journals have emerged.Over the past decade,there has been a considerable body of evidence in Chinese systematic reviews on TCM for chronic diseases such as diabetes,angina pectoris,and osteoarthritis.In English-language studies,non-pharmacological therapies like acupuncture have been more widely reported,and some high-impact studies have emerged.However,challenges remain,such as issues with research transparency and methodological standardization.Future efforts should focus on establishing transparent systems and quality control mechanisms to further enhance the reliability,accuracy,and dissemination of TCM evidence-based research.

In order to study the effects of prostaglandin D2(PGD2)on cow bone marrow-derived macrophages induced by E.coli,cultured cow bone marrow-derived macrophages were taken as the research object.The effects of endogenous and exogenous PGD2 on the secretion and phagocytosis of E.coli induced proinflammatory cytokines(IL-1β,IL-6 and TNF-α)in macrophages were ana-lyzed.The results showed that the synthesis of PGD2 in macrophages induced by E.coli is depend-ent on the natural pattern recognition receptors TLR2,TLR4 and NLRP3.Inhibition of endogenous PGD2can down-regulate the secretion of pro-inflammatory cytokines(IL-1β,IL-6 and TNF-α)in E.coli induced macrophages(P＜0.001),and inhibition of endogenous PGD2 can enhance the kill-ing function of macrophages to a certain extent(P＜0.01).In addition,exogenous PGD2 could up-regulate the secretion of pro-inflammatory cytokines(IL-1β,IL-6 and TNF-α)in macrophages af-ter E.coli stimulation(P＜0.01),and exogenous PGD2 could weaken the killing function of mac-rophages within a certain concentration range(P＜0.01).Results indicated that PGD2 had certain effects on the secretion of cytokines and phagocytosis and killing function of macrophages induced by E.coli.

Objective:To analyze the effect of long noncoding RNA (lncRNA) small nucleolar RNA host gene 16 (SNHG16) on the radiosensitivity of cervical cancer cells and explore its regulatory role in the miR-455-3p/ nuclear factor-κB (NF-κB) signaling pathway.Methods:The expression levels of lncRNA SNHG16 and miR-455-3p in human normal cervical epithelial cells H8, human cervical cancer cells SiHa, and radioresistant cervical cancer cells SiHa-R were detected by real-time reverse transcription polymerase chain reaction. SiHa-R cells were transfected separately, and then given a single dose of 4 Gy X-ray irradiation and continued to be cultured for subsequent experiments. The cells in each group were named siRNA-NC, siRNA-SNHG16 (interfering lncRNA SNHG16), NC mimic, miR-455-3p mimic (overexpressing miR-455-3p), siRNA-SNHG16+inhibitor NC, and siRNA-SNHG16+miR-455-3p inhibitor groups, respectively. The survival fraction of SiHa-R cells was detected by clone formation assay. The apoptosis rate of SiHa-R cells was analyzed by flow cytometry. The expression levels of apoptotic proteins [cysteine-containing aspartate-specific protease (Caspase)-3, Caspase-9, Bax] and NF-κB signaling pathway related proteins [NF-κB p65, phosphorylated (p)-NF-κB p65, p-IκB (inhibitory protein of NF-κB)] were measured by Western blot. The targeting relationship between lncRNA SNHG16 and miR-455-3p was determined by dual luciferase reporter gene assay. Comparison among different groups was conducted by one-way ANOVA, and paired comparison was carried out by LSD t-test. Comparison between two groups was performed by t-test. Results:Compared with H8 cells, the expression levels of lncRNA SNHG16 were increased in SiHa and SiHa-R cells, and SiHa-R cells had a higher level than SiHa cells. The expression levels of miR-455-3p were decreased in SiHa and SiHa-R cells, and SiHa-R cells had a lower level than SiHa cells (all P<0.001). Compared with the siRNA-NC group, the survival fraction of SiHa-R cells in the siRNA-SNHG16 group was decreased, the radiosensitization ratio (SER) was 1.571 (>1), the apoptosis rate and levels of Caspase-3, Caspase-9, and Bax proteins were increased, while the levels of p-NF-κB p65 and p-IκB proteins were decreased (all P<0.001). lncRNA SNHG16 could target miR-455-3p. Compared with the NC mimic group, miR-455-3p level in the miR-455-3p mimic group was increased, cell survival fraction was decreased, the SER was 1.826 (>1), the apoptosis rate and the levels of Caspase-3, Caspase-9, Bax proteins were increased, and the levels of p-NF-κB p65 and p-IκB proteins were decreased (all P<0.001). Inhibition of miR-455-3p expression could weaken the effect of interfering with lncRNA SNHG16 expression on SiHa-R cell apoptosis, radiotherapy sensitivity, and NF-κB signaling pathway (all P<0.001). Conclusions:Interference with lncRNA SNHG16 expression could induce the apoptosis of cervical cancer cells and enhance their radiation sensitivity by regulating the miR-455-3p/NF-κB signaling pathway.
