Parkinson's disease （PD） is a complex neurodegenerative disease involving multiple systems and neurotransmitters. Due to the high clinical heterogeneity of PD，it is urgent to establish a comprehensive and long-term traditional Chinese medicine （TCM） management model. In this paper，the conceptual framework of full-cycle management of PD is preliminarily constructed：based on the evolution of the pathophysiological mechanisms of protein deposition and neurotransmitter disorder in PD，the three-stage syndrome characteristics of the prodromal stage （predominant healthy Qi with subtle pathogenic factors），the early clinical stage （declining healthy Qi with growing pathogenic factors） and the middle and late stages （overwhelming pathogenic factors with deficient healthy Qi） are longitudinally described. Through the syndrome differentiation of visceral manifestations，the etiology and pathogenesis of PD motor and non-motor symptoms were comprehensively analyzed，while the matching treatment methods and prescriptions were inferred，and the modular scheme of the combining main symptoms，accompanying symptoms and secondary symptoms was proposed. The conceptual gap of TCM regarding motor complications （'variable syndrome'） and PD-related hyperpyrexia syndrome （'critical syndrome'） was explained. This framework reflects the characteristics of combination of disease and syndrome and overall constant motion，and provides new theories and research ideas for individualized and whole-process management of PD in TCM.

To explore the advantages of traditional Chinese medicine （TCM） and integrative TCM-Western medicine approaches in the treatment of diabetic microvascular complications （DMC）， refine key pathophysiological insights and treatment principles， and promote academic innovation and strategic research planning in the prevention and treatment of DMC. The 38th session of the Expert Salon on Diseases Responding Specifically to Traditional Chinese Medicine， hosted by the China Association of Chinese Medicine， was held in Beijing， 2024. Experts in TCM， Western medicine， and interdisciplinary fields convened to conduct a systematic discussion on the pathogenesis， diagnostic and treatment challenges， and mechanism research related to DMC， ultimately forming a consensus on key directions. Four major research recommendations were proposed. The first is addressing clinical bottlenecks in the prevention and control of DMC by optimizing TCM-based evidence evaluation systems. The second is refining TCM core pathogenesis across DMC stages and establishing corresponding "disease-pattern-time" framework. The third is innovating mechanism research strategies to facilitate a shift from holistic regulation to targeted intervention in TCM. The fourth is advancing interdisciplinary collaboration to enhance the role of TCM in new drug development， research prioritization， and guideline formulation. TCM and integrative approaches offer distinct advantages in managing DMC. With a focus on the diseases responding specifically to TCM， strengthening evidence-based support and mechanism interpretation and promoting the integration of clinical care and research innovation will provide strong momentum for the modernization of TCM and the advancement of national health strategies.

Objective To provide a scientific basis for vector prevention and control in port areas, vector monitoring has been conducted continuously to characterize the composition, density, and seasonal fluctuations of vectors across 21 port-areas of Shandong province from 2017 to 2023. Methods In accordance with the Regional Vector Monitoring Plan for Frontier Ports, vector surveillance of mosquitoes, flies, cockroaches, rodents, and other disease vectors was performed. Data were analyzed to describe vector community composition and identify seasonal fluctuations. Results A total of 601 rodents belonging to 1 family, 4 genera, and 4 species were captured. Three dominant rodent species inhabit port areas. In addition, 88 104 mosquitoes were captured and classified into 3 subfamilies, 4 genera, and 12 species; 38 959 flies were trapped and classified into 8 families,31 genera, and 51 species, including 9 dominant fly species in port-areas; and 54 672 captured cockroaches were classified into 2 families,4 genera, and 4 species, with Blattella germanica as the dominant species. Conclusions Significant vector community changes(P＜0.005)have been identified after the epidemic. To improve the pertinence and efficacy of port health quarantine work, continuous and strong attention should be paid to vector compositions and population densities at Shandong ports.

Background: Surgeons face challenges in selecting cost-effective and biologically active agents for rotator cuff healing, given the numerous commercial products available, such as polydeoxyribonucleotide (PDRN) and atelocollagen (ATC). However, the precise efficacy of PDRN and ATC in rotator cuff healing remains debatable, and there is currently a lack of studies directly comparing the effects of the 2 agents on repaired cuff tendons. Therefore, the purpose of this study was to compare the efficacy of PDRN and ATC on bone-to-tendon interface (BTI) healing using a chronic rotator cuff tear (RCT) model in rabbits. Methods: Forty-eight rabbits were randomly divided into 3 groups. To create chronic RCT models, transected tendons were left untreated for 6 weeks, and then were repaired in a transosseous manner with PDRN and ATC injection into the repair site according to group allocation (group A: saline, group B: PDRN, group C: ATC; n = 16 per group). Genetic and immunofluorescence analyses were performed at 4 weeks after surgery. Furthermore, genetic, histologic, and biomechanical analyses were performed at 12 weeks after surgery. Results: At 4 weeks after surgery, ATC-injected shoulders showed the highest mRNA expression levels of collagen type I alpha 1 and aggrecan compared to the other 2 groups (p < 0.001 and p = 0.002, respectively). Meanwhile, there was more preliminary fibrocartilaginous matrix formation in the ATC-injected group. At 12 weeks after surgery, ATC-injected shoulders demonstrated better collagen fiber continuity and orientation, denser collagen fibers, a more mature bone-to-tendon junction, and greater fibrocartilage layer formation compared to the other 2 groups (all p < 0.001). Furthermore, ATC-injected shoulders also demonstrated a significantly higher load-to-failure value (40.4 ± 4.5 N/kg) than the remaining groups (group A, 26.7 ± 3.0 N/kg; group B, 32.8 ± 4.2 N/kg; p < 0.001). Conclusions ATC demonstrated superior efficacy in promoting BTI healing following surgical repair in a chronic RCT model of rabbits.

Diabetic nephropathy(DN)ranks as a frequent and serious complication in diabetes mellitus,and it's a key factor in chronic kidney disease and end-stage renal disease(ESRD),greatly diminishing the life quality of patients.Presently,the conventional treatment approaches for DN mainly involve strict regulation of blood sugar and pressure,in conjunction with the application of renin-angiotensin-aldosterone system inhibitors.While these therapies can slow down the advancement of DN,they are ineffective in stopping its final development into ESRD.Lately,the involvement of the gut-kidney axis in the development and advancement of DN has attracted growing interest.Individuals suffering from DN show changes in the variety of gut microbiota,which are crucial in the development and management of DN due to metabolic interactions with the host.The goal of this analysis is to explore the fundamental processes of gut microbiota's role in DN and explore treatment approaches focusing on gut microbiota,aiming to offer new perspectives for the clinical handling of DN.

Objective To investigate the effects of synovial fluid from patients with rheumatoid arthritis(RA)on the polarization of normal neutrophils and the MEK/ERK signaling pathway,thereby providing experimental evidence to elucidate the pathological mechanisms of RA and offering novel insights into its treatment.Methods Synovial fluid samples were collected from 20 RA patients and 20 osteoarthritis(OA)patients.ELISA was used to measure the levels of interferon-gamma(IFN-γ),tumor necrosis factor-alpha(TNF-α),transforming growth factor-beta(TGF-β)and interleukin-8(IL-8)in the synovial fluid.Neutrophils were isolated from the peripheral blood of healthy donors,and their purity was confirmed by flow cytometry.Neutrophils were then treated with synovial fluid and divided into four groups:Control(untreated),RA(treated with 10％RA synovial fluid),OA(treated with 10％OA synovial fluid),and anti-IFN-β(treated with 20 μg anti-IFN-β antibody as an N2-type control).Western blot was used to assess the changes in the expression of IFN-γ,TNF-α,TGF-β,MEK,p-MEK,ERK and p-ERK.Additionally,the MEK inhibitor PD0325901 was used to block the MEK/ERK pathway,and subsequent changes in IFN-γ and TGF-β expression in neutrophils were evaluated.Results The levels of IFN-γ,TNF-α,TGF-β and IL-8 in the synovial fluid of RA patients were significantly higher than those in OA patients.After intervention with RA synovial fluid,the relative expression of IFN-γ and TNF-α in neutrophils were significantly increased compared to those in the untreated control group and the OA group.While,TGF-β expression in the RA group was lower than that in both the control and anti-IFN-β groups.The relative expression of p-MEK and p-ERK in the RA group were significantly higher than those in the control,OA and Anti-IFN-β groups.Upon addition of the MEK inhibitor,the relative expression of p-MEK and p-ERK were reduced.Furthermore,in both the RA and OA groups,the relative expression levels of IFN-γ decreased,while the expression of TGF-β increased.Conclusion Synovial fluid from RA patients contains higher of IFN-γ,TNF-αand TGF-β,which activate neutrophils through phosphorylation of the MEK/ERK signaling pathway,promoting their polarization toward the pro-inflammatory N1 phenotype.

Purpose To investigate the clinicopathological features of traditional serrated adenoma(TSA).Methods A retrospective analysis was conducted on the clinical data,endoscopic,and pathological features of 200 TSA patients.HE staining and immunohistochemical staining were performed.The clinical pathological features were statistically analyzed using x2 test,and relevant literature was reviewed.Results There were 114 males(57.0％)and 86 females(43.0％),with ages ranging from 27 to 92 years(mean age 56.2 years).Among the patients,147(73.5％)were aged ≥ 50 years,and 53(26.5％)were aged＜50 years.Of the 207 TSA lesions,143(69.1％)were located in the distal colon and rectum,while 57(27.5％)were in the proximal colon and rectum.Endoscopic features included 72 lesions(34.8％)with a perpendiculated appearance,48 lesions(23.2％)with a flat appear-ance,and some exhibiting a pinecone-like appearance.The maximum diameter of the lesions was ≤ 10 mm in 136 ca-ses(65.7％),and＞10 mm in 71 cases(34.3％).The typical histopathological features of TSA included serrated contours,eosinophilic cytoplasm,pencil-like nuclei,and ectopic crypt foci.The most common pathological type was the classic TSA(152 lesions,73.4％),followed by the mucin-rich TSA(39 lesions,18.8％).12 cases(5.8％)of TSA exhibited high-grade intraepithelial neoplasia(HGIN)and 3 case(1.5％)of TSA progressed to carcinoma,con-sistent with TSA-originated colorectal cancer(TSA-CRC).Immunophenotype:in 34 cases TSA,Ki67 showed diffuse positivity in basal cells and scattered positivity on the surface.In all 35 cases TSA,p53 showed weak positive nuclear positivity(1％to 60％),and PTEN and MLH1 were retained.In the 12 cases of TSA with HGIN and 3 cases of TSA-CRC,Ki67 showed diffusely positive,CK20 was strongly positive diffusely,and MLH1 was retained.In 9 cases of TSA with HGIN,p53 was diffusely strongly positive,and in 12 cases,PTEN was lost.All 3 cases of TSA-CRC showed dif-fuse strong nuclear p53 positivity.The molecular detection showed there were BRAF V600E gene mutation in 8 cases.There were 6 cases with KRAS G12V mutation as well as 1 case with KRAS G13D mutation among the 7 cases of KRAS mutation.The primary surgical approach(111 cases,53.6％)was endoscopic mucosal resection(EMR).Conclu-sion TSA exhibits characteristic histological and endoscopic features.Lesions with a maximum diameter＞10 mum are more likely to progress to HGIN or adenocarcinoma.It is crucial to enhance the awareness of pathologists and clini-cians,particularly regarding TSA with atypical hyperplasia or invasive carcinoma,to avoid misdiagnosis and missed di-agnoses.

Objective To investigate the distribution and antimicrobial resistance profiles of clinically isolated Haemophilus influenzae and Moraxella catarrhalis in hospitals across China from 2015 to 2021,and provide evidence for rational use of antimicrobial agents.Methods Data of H.influenzae and M.catarrhalis strains isolated from 2015 to 2021 in CHINET program were collected for analysis,and antimicrobial susceptibility testing was performed by disc diffusion method or automated systems according to the uniform protocol of CHINET.The results were interpreted according to the CLSI breakpoints in 2022.Beta-lactamases was detected by using nitrocefin disk.Results From 2015 to 2021,a total of 43 642 strains of Haemophilus species were isolated,accounting for 2.91％of the total clinical isolates and 4.07％of Gram-negative bacteria in CHINET program.Among the 40 437 strains of H.influenzae,66.89％were isolated from children and 33.11％were isolated from adults.More than 90％of the H.influenzae strains were isolated from respiratory tract specimens.The prevalence of β-lactamase was 53.79％in H.influenzae strains.The H.influenzae strains isolated from children showed higher resistance rate than the strains isolated from adults.Overall,779 strains of H.influenzae did not produce β-lactamase but were resistant to ampicillin(BLNAR).Beta-lactamase-producing strains showed significantly higher resistance rates to these antimicrobial agents than the β-lactamase-nonproducing strains.Of the 16 191 M.catarrhalis strains,80.06％were isolated from children and 19.94％isolated from adults.M.catarrhalis strains were mostly susceptible to both amoxicillin-clavulanic acid and cefuroxime,evidenced by resistance rate lower than 2.0％.Conclusions The emergence of antibiotic-resistant H.influenzae due to β-lactamase production poses a challenge for clinical anti-infective treatment.Therefore,it is very important to implement antibiotic resistance surveillance for H.influenzae and guide rational antibiotic use.All local clinical microbiology laboratories should actively improve antibiotic susceptibility testing and strengthen antibiotic resistance surveillance for H.influenzae.

Objective To understand the changing composition and antibiotic resistance of bacterial species in the clinical isolates from outpatient and emergency department(hereinafter referred to as outpatients)and inpatient children over time in various hospitals,and to provide laboratory evidence for rational antibiotic use.Methods The data on clinically isolated pathogenic bacteria and antimicrobial susceptibility of isolates from outpatients and inpatient children in the CHINET program from 2015 to 2021 were collected and analyzed.Results A total of 278 471 isolates were isolated from pediatric patients in the CHINET program from 2015 to 2021.About 17.1％of the strains were isolated from outpatients,primarily group A β-hemolytic Streptococcus,Escherichia coli,and Staphylococcus aureus.Most of the strains(82.9％)were isolated from inpatients,mainly SS.aureus,E.coli,and H.influenzae.The prevalence of methicillin-resistant S.aureus(MRSA)in outpatients(24.5％)was lower than that in inpatient children(31.5％).The MRSA isolates from outpatients showed lower resistance rates to the antibiotics tested than the strains isolated from inpatient children.The prevalence of vancomycin-resistant Enterococcus faecalis or E.faecium and penicillin-resistant S.pneumoniae was low in either outpatients or inpatient children.S.pneumoniae,β-hemolytic Streptococcus and S.viridans showed high resistance rates to erythromycin.The prevalence of erythromycin-resistant group A β-hemolytic Streptococcus was higher in outpatients than that in inpatient children.The prevalence of β-lactamase-producing H.influenzae showed an overall upward trend in children,but lower in outpatients(45.1％)than in inpatient children(59.4％).The prevalence of carbapenem-resistant Klebsiella pneumoniae(CRKpn),carbapenem-resistant Pseudomonas aeruginosa(CRPae)and carbapenem-resistant Acinetobacter baumannii(CRAba)was 14％,11.7％,47.8％in outpatients,but 24.2％,20.6％,and 52.8％in inpatient children,respectively.The prevalence of multidrug-resistant E.coli,K.pneumoniae,Proteus mirabilis,P.aeruginosa and A.baumannii strains was lower in outpatients than in inpatient children.The prevalence of fluoroquinolone-resistant E.coli,ESBLs-producing K.pneumoniae,ESBLs-producing P.mirabilis,carbapenem-resistant E.coli(CREco),CRKpn,and CRPae was lower in children in outpatients than in inpatient children,but the prevalence of CRAba in 2021 was higher than in inpatient children.Conclusions The distribution of clinical isolates from children is different between outpatients and inpatients.The prevalence of MRSA,ESBL,and CRO was higher in inpatient children than in outpatients.Antibiotics should be used rationally in clinical practice based on etiological diagnosis and antimicrobial susceptibility test results.Ongoing antimicrobial resistance surveillance and prevention and control of hospital infections are crucial to curbing bacterial resistance.
