ObjectiveTo observe the short-term and long-term efficacy of traditional Chinese medicine （TCM） surgical operations in treating mixed hemorrhoids. MethodsA multi-center retrospective cohort study was conducted， collecting clinical data from 17，831 mixed hemorrhoid surgery patients in 8 top-tier TCM hospitals in Jiangsu Province. Standardized and structured datasets were obtained through artificial intelligence models. Patients who underwent western surgical treatment were categorized into the western surgery group （11,646 cases）， and those receiving TCM surgical operations were categorized into the TCM surgery group （6185 cases）. Propensity score matching （1∶1 matching） was used to balance baseline data between groups. The primary outcome was the one-year recurrence rate， and secondary outcomes included the main symptoms （rectal bleeding， degree of prolapse） and secondary symptoms （anal distension， anal edema， wound secretion and exudation， anal stenosis， residual skin tags， perianal itching， and anal pain） measured on days 7， 28， and 60 after discharge. ResultsAfter matching， 2194 patients were included in each group. Symptom scores showed that at 28 days after discharge， the TCM surgical group had superior improvement in rectal bleeding ［OR=5.786， 95%CI （3.092，10.827）］， degree of prolapse ［OR=4.510， 95%CI （1.649，12.333）］， and anal edema ［OR=3.188， 95%CI （1.295，7.845）］ compared to the western surgical group. At 60 days post-discharge， the TCM group still showed advantages in improving rectal bleeding ［OR=5.237， 95%CI （1.077，25.464）］ and anal pain ［OR=11.697， 95%CI （1.186，115.336）］ （P＜0.05）. Long-term follow-up showed that the one-year recurrence rate in the TCM surgery group was 1.1% （8/726）， while that in the western surgery group was 2.3% （10/444）， with no statistically significant difference between the two groups （P＞0.05）. ConclusionBased on real-world data， TCM surgical treatment for mixed hemorrhoids shows significant short-term symptom improvement， particularly in terms of hemostasis， reducing swelling， and alleviating prolapse of anal masses.

Objective Objective To analyze the potential spatial factors affecting the genetic differentiation of Oncomelania hupensis robertsoni in Yunnan Province. Methods A total of 13 administrative villages were selected from schistosomiasis-endemic areas of Yunnan Province as O. hupensis snail sampling sites. At least 200 snails were collected in each site, and the spatial variable data of each site were recorded, including longitude, latitude and altitude. Thirty active and Schistosoma japonicum uninfected O. hupensis snails were selected from each sampling site by means of the crawling method and the cercarial shedding method. Genomic DNA was extracted from O. hupensis snails. Following PCR amplification, purification of PCR amplification products and sequencing, the gene sequences of O. hupensis snail samples were spliced and edited using the DNAstar software and the NCBI database to yield the complete mitochondrial sequences of O. hupensis snails at each sampling site, and the mitochondrial genetic distance matrix of O. hupensis robertsoni was calculated at each sampling site. The geographical coordinates of each sampling site were marked using the software ArcGIS 10.2, and the straight-line geographical distance between each sampling site was calculated. The altitude difference, longitude difference and latitude difference between each sampling site were calculated using the Excel software, and the correlation between the mitochondrial genetic distance matrix of O. hupensis robertsoni and each spatial variable matrix was examined by using the Mantel test at 13 sampling sites in Yunnan Province. Results Among the 13 O. hupensis snail sampling sites in Yunnan Province, the largest mitochondrial genetic distance of O. hupensis robertsoni snail populations was seen between Anding Village, Nanjian Yi Autonomous County and Caizhuang Village, Midu County (26.244 2), and the largest geographical distance was seen between Dongyuan Village, Gucheng District and Cangling Village, Chuxiong County (272.64 km). The highest altitude difference was seen between Anding Village, Nanjian Yi Autonomous County and Dongyuan Village, Gucheng District (1 086.10 m), and the largest longitude difference was found between Qiandian Village, Eryuan County and Cangling Village, Chuxiong County (1.86°), while the largest latitude difference was measured between Leqiu Village, Nanjian Yi Autonomous County and Dongyuan Village, Gucheng District (1.81°). In addition, the mitochondrial genetic distance of O. hupensis robertsoni snail populations was positively correlated with altitude at 13 snail sampling sites in Yunnan Province (r = 0.542 8, P < 0.001), and showed no significant correlations with geographical distance (r = 0.093 4, P > 0.05), longitude (r = −0.199 5, P > 0.05) or latitude (r = 0.205 7, P > 0.05). Conclusion Altitude may be a potential spatial factor affecting the genetic differentiation of O. hupensis robertsoni in Yunnan Province.

Objective To investigate the effect of Jiawei Simiao powder on the Toll-like receptor 4(TLR4)/nuclear factor-κB(NF-κB)signaling pathway through miR-146a in monosodium urate(MSU)crystal-induced RAW264.7 macrophage inflammation models,and to explore its anti-inflammatory mechanism.Methods A cell model of gouty arthritis was established by inducing RAW264.7 cells with MSU crystals.Cells were divided into control,model,Jiawei Simiao powder,and colchicine groups and cell viability was assessed using the CCK-8 method.Levels of interleukin(IL)-1β,IL-6,and tumor necrosis factor(TNF)-α were measured by enzyme-linked immunosorbent assay.Expression levels of miR-146a miRNA and TLR4,myeloid differentiation factor 88(MyD88),TNF receptor-associated factor 6(TRAF6),and NF-κB p65 mRNA were detected by quantitative real-time polymerase chain reaction amplification technology,and protein expression levels of TLR4,MyD88,TRAF6,and phospho(p)-NF-κB p65 were evaluated by Western blot.Results miR-146a expression was significantly decreased in the model group compared with the control group(P＜0.01),while mRNA and protein expression levels of TLR4,MyD88,and TRAF6,and protein expression of p-NF-κB p65,IL-1β,IL-6,and TNF-α were significantly increased(P＜0.01).In contrast,miR-146a expression was significantly increased(P＜0.01)and mRNA and protein expression of TLR4,MyD88,and TRAF6,and p-NF-κB p65 protein expression(P＜0.01),as well as IL-1β,IL-6,and TNF-α levels(P＜0.05)were significantly decreased in the Jiawei Simiao powder and colchicine groups.Conclusions Jiawei Simiao powder may alleviate MSU crystal-induced macrophage inflammatory responses by upregulating miR-146a,suppressing TLR4/NF-κB signaling pathway activation,and decreasing secretion of inflammatory factors.

Objective This study aimed to investigate the antimicrobial resistance profiles of bacterial strains isolated from pediatric intensive care units(PICU)in China for better antimicrobial therapy.Methods Clinical isolates were collected from 17 institutions,including tertiary care children's hospitals and pediatric department of tertiary general hospitals in China from January 1,2020 to December 31,2022.Antimicrobial susceptibility testing was carried out according to a unified protocol using Kirby-Bauer method or automated systems.Results were interpreted according to the breakpoints released by the Clinical and Laboratory Standards Institute(CLSI)in 2020.Results A total of 10 688 isolates were collected,including gram-positive organisms(39.2％)and gram-negative organisms(60.8％).The top three organisms were S.aureus(13.6％,1 453/10 688),A.baumannii(10.0％,1 067/10 688),and coagulase-negative Staphylococcus(9.9％,1 058/10 688).Multi-drug resistant organisms(MDROs)were very common in children.The prevalence of methicillin-resistant Staphylococcus aureus(MRSA),carbapenem-resistant Enterobacterales(CRE),carbapenem-resistant E.coli,carbapenem-resistant K.pneumoniae(CRKP),carbapenem-resistant A.baumannii(CRAB),and carbapenem-resistant P.aeruginosa(CRPA)was 41.1％,19.4％,8.8％,30.9％,67.4％,and 28.8％,respectively.Overall,more than 50％of Enterobacteriales isolates were resistant to cephalosporins,while nearly 25％of Enterobacteriales isolates were resistant to carbapenems.MDROs were highly resistant to commonly used antibiotics.More than 80％of CRE and CRAB strains were resistant to all beta-lactam antibiotics.CRE and CRAB showed low resistance rates to tigecycline and polymyxin.CRPA showed lower resistance rates to piperacillin,beta-lactamase inhibitor combinations than the resistance rates to third and fourth generation cephalosporins.All of the Staphylococcus and Enterococcus isolates were susceptible to vancomycin and tigecycline.None of PRSP strains isolated from meningitis and nonmeningitis samples were resistant to rifampicin,vancomycin,or linezolid.The prevalence of β-lactamase-negative ampicillin-resistant(BLNAR)strains was 43.3％in Haemophilus influenzae.Conclusions MDROs were prevalent in PICU.It is necessary to establish an effective multidisciplinary team(MDT)to control the antimicrobial resistance.

Acute gouty arthritis is an inflammatory disease characterized by redness,swelling,heat,and pain in the joints.It mostly occurs at the distal ends of the limbs,especially in the toe joints.The six climatic exopathogens,which include wind,cold,summer-heat,dampness,dryness,and fire(heat),are the general term for exogenous pathogenic factors.This article explores the pathogenesis and treatment approaches of acute gouty arthritis from the perspective of the six climatic exopathogens.All the six climatic exopathogens can lead to the occurrence of acute gouty arthritis,among which"fire"is the most closely associated with this disease.Wind-pathogenic factor accumulates without dissipation and transforms into fire internally;cold-pathogenic factor congeals without warmth and transforms into fire after long-term stagnation;when wind and dampness interact and cannot circulate,they stagnate and transform into fire;dry-pathogenic factor accumulates internally without release,transforms into fire,and consumes yin;fire stagnates and intensifies when it cannot be discharged.It can be seen that the six climatic exopathogens are the inducing factors for acute gouty arthritis,and"fire"is the key factor and the general summary of the disease occurrence.Therefore,it is proposed that the core therapeutic principle is clearing heat-fire.Simultaneously,combined with clinical practice,methods are supplemented,such as expelling wind,dredging collaterals and relieving pain;warming yang,dispelling cold and eliminating arthralgia;drying dampness,strengthening the spleen and facilitating joint function;and moistening dryness,nourishing yin and dredging collaterals.Acute gouty arthritis is not simply treating based on the theory of fire.By tracing back to the root cause,treating both the symptoms and the root cause,it is hoped that this can provide a theoretical basis for the clinical treatment of acute gouty arthritis from the perspective of the six climatic exopathogens and broaden the therapeutic ideas.

Objective:The clinical symptoms of children with global developmental delay (GDD) were analyzed to provide the scientific basis for the intervention of children with GDD.Methods:The results of the neuro-psychobehavioral scale were collected from 32 511 children with GDD from June 2020 to November 2023. Inclusion criteria: Children diagnosed with GDD according to the Diagnostic and Statistical Manual of Mental Disorders-V, ages 0.0 to 4.9 years. Exclusion criteria: children with common hearing impairment and visual impairment. The Chi-square tests were used for statistical analysis.Results:There were more boys than girls with GDD in outpatient clinics (68.2% vs. 31.8%). Among the children, the proportion of developmental delay in 5, 4, 3, and 2 domains was 31.1%, 23.4%, 22.9% and 22.6% respectively. The rate of delay in 2-3 domains was lower in boys (41.9%) than in girls (53.1%). The rate of delay in 4-5 domains was higher in boys (58.1%) than in girls (46.9%) ( χ2=352.11, P<0.001). Overall, outpatient GDD decreased with age. From 1.0-1.9 to 4.0-4.9 years of age, the proportion of children with developmental delay in 5 domains increased with age (18.2%, 36.4%, 43.9%, 52.4%). Among children aged 0.0-0.9 years, the proportion of 2 domains of developmental delay was higher (33.4%).Among children aged 1.0-1.9 years, the proportion of 2-3 domains of developmental delay was higher (30.7%). Among children aged 2.0-, 3.0-, 4.0-4.9 years, the proportion of developmental delay in 5 domains was higher (36.4%, 43.9%, 52.4%).

Objective:To establish reference values for clot waveform analysis (CWA) and analyze their diagnostic efficacy in distinguishing acquired hemophilia A (AHA) and lupus anticoagulant (LA)-positive patients.Methods:Case-Control Study. A total of 391 healthy individuals(260 males and 131 females) with a mean age of 45.53±14.85 years were enrolled at Nanyang central Hospital between January 6, 2023 and October 10, 2024. Prothrombin time (PT), activated partial thromboplastin time (APTT), and thrombin time (TT) were measured to establish reference ranges for the CWA parameters, including maximal reaction velocity (Min1), maximal reaction acceleration (Min2), and maximal reaction deceleration (Max2). A total of 158 definitively diagnosed AHA and LA-positive patients (mean age:42.46±14.83 years), including 34 AHA patients and 124 LA-positive patients, were recruited. The Mann Whitney U test was used to analyze the differences in the CWA parameters between the two groups. The diagnostic efficacy of CWA parameters in distinguishing AHA and LA-positive patients was evaluated using the area under the receiver operating characteristic(ROC) curve AUC and the cut-off values were calculated. Results:The reference values for PT-Min1, APTT-Min1, APTT-Min2, APTT-Max2, TT-Min1, TT-Min2, TT-Max2 were 203.41-516.89, 144.63-324.03, 526.46-1 190.03, -404.96±157.22, 159.17±60.34, 272.29-686.99, and -289.47--113.76, respectively. Compared with the CWA parameters in AHA patients, APTT-Max2 was significantly lower in LA-positive patients [-422.74(-577.50, -239.22) vs. -68.87(-92.85,30.28), Z=-7.43, P<0.01], while PT-Min1, APTT-Min1, APTT-Min2, TT-Min1, TT-Min2 were significantly elevated [287.01(188.03, 382.50) vs. 107.45(90.20, 151.39), 972.88(601.20, 1 351.19) vs. 229.10(118.38, 371.67), Z=6.68, 6.69, all P<0.01]. ROC analysis demonstrated the APTT-CWA parameter exhibited high diagnostic efficacy in patients with AHA (AUC>0.900 for both).Additionally, APTT-Min1 and APTT-Max2 were found to be useful in distinguishing between AHA patients and those with LA-positive status accompanied by APTT prolongation (AUC=0.660, 0.700, respectively). Conclusions:Reference values for CWA parameters were successfully established. The APTT-CWA is useful for differentiating between AHA and LA-positive patients and APTT-Max2 demonstrated a good diagnostic value in differentiating AHA patients from those with LA-positive status accompanied by APTT prolongation.
