BACKGROUND: Most studies have evaluated disability-adjusted life years (DALYs) of colorectal cancer (CRC) patients based on a set of generic disability weights (DWs). This study aimed to apply local CRC-stage-specific DWs to estimate the burden of DALYs for CRC (CRC-DALYs) in populations in China and consider the influence of local screening coverage of CRC. METHODS: A prevalence-based model was constructed using data from various sources. Years lived with disability (YLDs) were estimated mainly via cumulative prevalence data (based on CRC incidence rates, population numbers, and survival rates), stage-specific proportions of CRC, and DWs of the local population. Years of life lost (YLLs) were calculated based on the CRC mortality rates and standard life expectancies. CRC incidence and mortality rates for the years 2020, 2025, and 2030 were estimated by joinpoint regression, and the corresponding DALYs were predicted. The main assumption was made for CRC screening coverage. Sensitivity analyses were used to assess the impact of population, DWs, and coverage. RESULTS: In 2017, among the Chinese population, the estimated number of CRC-DALYs was 4,303,314 (11.9% for YLDs). If CRC screening coverage rate in China (2.3%) remains unchanged, the overall DALYs in 2030 are predicted to increase by 37.2% (45.1% of those aged ≥65 years). More optimistically, the DALYs would then decrease by 0.7% in 2030 (from 5,902,454 to 5,860,200) if the coverage could be increased to 25.0%. A sensitivity analysis revealed that using local DWs would change the base-case values by 5.7%. CONCLUSIONS The estimated CRC-DALYs in China using population-specific DWs were considerably lower (with a higher percentage of YLDs) than the global burden of disease (GBD) estimates (5,865,004, of 4.6% for YLDs), suggesting the impact extent of applying local parameters. Sustainable scale-up CRC screening needs to be in place to moderate the growth trend of CRC-DALYs in China.

Traditional Chinese medicine(TCM) capable of clearing heat and removing toxin is most commonly used in clinical practice and has the effect of removing fire-heat and toxin. Studies have shown that most of the Ilex plants have the effect of clearing heat and removing toxin, among which the varieties of I. cornuta, I. pubescens, I. rotunda, I. latifolia, and I. chinensis are most widely used. These plants generally contain triterpenoids and their glycosides, alkaloids, flavonoids, phenylpropanoids, and other chemical components, especially pentacyclic triterpenoids. According to their skeletons, pentacyclic triterpenoids can be divided into the oleanane type, the ursane type, the lupinane type, etc. Among them, ursane-type components are the most abundant, and 136 species have been found so far. These components have been proved to have pharmacological effects such as anti-inflammatory, anti-tumor, hypolipidemic, anti-thrombosis, cardiomyocyte-protective, antibacterial, and hepatoprotective effects. Therefore, this paper systematically reviews the domestic and foreign literature on Ilex plants with a focus on the research progress on pentacyclic triterpenoids and their pharmacological activities, aiming to provide reference for the development of TCM resources with the effect of clearing heat and removing toxin.

Objective This study aimed to provide an effective scientific basis for prevention and control of cockroaches on aircrafts by identifying cockroach-carried pathogens,and assess the insecticidal efficacy of gel bait mediated cockroach control on aircrafts,to provide technical guidance for aircraft disinsection.Methods Cassette-trapping was used to trap cockroaches,and the carried pathogens were detected using bacterial cultivation techniques.The gel bait mediated killing rate was calculated after 1,7,and 30 d by field application of gel bait.Results A total of 411 cockroaches were captured,and all were identified as Blattella germanica.26 strains of pathogenic bacteria were isolated from the trapped cockroaches.The killing rates of cockroaches were 58.8％-96.3％with 1-30 day application of gel bait.Statistically significant differences were observed in cockroach killing rates on different days(χ2=58.95,P<0.01).Conclusions B.germanica carry a large variety of pathogenic bacteria and opportunistic pathogens and are thus important infectious disease carriers.Gel bait agents have proven to be very effective against cockroaches on aircrafts.

Objective:To explore the application value of three-dimensional high-resolution anorectal manometry(3D-HRAM)model in the diagnosis and localization of anal sphincter injury after surgery for complex anal fistula.Methods:A prospective study was con-ducted on 92 patients who had undergone surgery for complex anal fistula in the Department of Coloproctology of The People's Hospi-tal Affiliated to Fujian University of Traditional Chinese Medicine from January 2023 to January 2024.The study was conducted in two stages.In the first stage,92 patients underwent 3D-HRAM and endoanal ultrasonography(EAUS)to examine the sphincter,and the data were compared with intraoperative records to evaluate the diagnostic efficiency and localization accuracy of 3D-HRAM and EAUS.In the second stage,92 patients who had been examined were grouped according to the presence or absence of symptoms of anal dysfunction to further verify the diagnostic and localization values of 3D-HRAM and EAUS for postoperative compensated/decompen-sated sphincter injury.Results:Among 92 patients,41 and 57 patients were diagnosed with sphincter injury through 3D-HRAM and EAUS,with a sensitivity of 61.19%and 85.07%,a specificity of 88%and 76%,an area under the curve of 0.739 and 0.813 calcu-lated by plotting the receiver operating characteristic curve,and a localization accuracy of 44.77%and 71.64%,respectively,showing significant differences between 3D-HRAM and EAUS(P=0.002),indicating that 3D-HRAM had lower diagnostic efficiency and local-ization accuracy than EAUS for anal sphincter injury after surgery for complex anal fistula.After grouping by symptoms,the diagnostic efficiency and localization accuracy of 3D-HRAM for symptomatic sphincter injury(decompensated)were significantly better than those for asymptomatic sphincter injury,and were similar to those of EAUS(P=0.763).Conclusion:The application advantage of 3D-HRAM lies in the diagnosis and localization of decompensated anal sphincter injury after surgery for complex anal fistula,which provides effective technical support for the study of anal defecation control mechanisms and injury compensation mechanisms.

Objective:To observe the relationship between serum insulin-like growth factor binding protein-3(IGFBP-3),insulin-like growth factor-1(IGF-1)and cardiac function and short-term prognosis in patients with dilated cardiomyopathy(DCM)complicated with heart failure(HF).Methods:102 patients with DCM complicated with HF were selected as study group and they were divided into good prognosis group and poor prognosis group based on prognosis,and 100 patients with simple DCM during the same period were selected as the control group.The cardiac function indicators[left ventricular end systolic volume(LVESV),left ventricular ejection fraction(LVEF),left ventricular end diastolic volume(LVEDV)]and serum IGFBP-3 and IGF-1 levels between the control group and the study group were compared.The correlation between cardiac function and IGFBP-3,IGF-1 was analyzed by pearson analysis.The serum IGFBP-3 and IGF-1 leveles between good prognosis group and poor prognosis group were compared,the correlation between prognosis and IGFBP-3,IGF-1 was analyzed by spearman.Receiver operating characteristic(ROC)curves were used to analyze the predictive value of serum levels of IGFBP-3 and IGF-1 alone and in combination for the short-term prognosis of DCM complicated with HF patients.Results:Compared with control group,study group had higher LVEDV,LVESV,IGFBP-3,IGF-1,and lower LVEF(P＜0.05).Pearson analysis results showed that,IGFBP-3 and IGF-1 were positively correlated with LVEDV and LVESV,while which was negatively correlated with LVEF(P＜0.05).Compared with good prognosis group,poor prognosis group had higher IGFBP-3,IGF-1(P＜0.05).Spearman correlation analysis results showed that,the levels of IGFBP-3 and IGF-1 were positively correlated with the poor prognosis of DCM complicated with HF patients(P＜0.05).The area under the curve(AUC)of serum IGFBP-3,IGF-1 levels,and their combined use for short-term prognosis of DCM complicated with HF patients were 0.715,0.749,and 0.831,respectively.Conclusion:Serum IGFBP-3 and IGF-1 levels are elevated in patients with DCM complicated with HF,and the changes in these two indicators are associated with poor cardiac function and prognosis in patients.The combined detection of IGFBP-3 and IGF-1 levels has a high predictive value for the short-term prognosis of DCM combined with HF.

Objective:To perform RHD gene detection on a blood sample with serological weak D phenotype.Methods:A specimen received by the People's Hospital of Zhijin County was serologically identified by the microcolumn gel method and saline method.RHD gene detection was conducted by the PCR-SSP method,and the full sequence determination of the 10 exons amplified was performed.The sequencing results were compared with the ISBT database to determine the genotype.Bioinformatics tool was used to predict the functional damage of mutant proteins,and Alphafold-3 was used for tertiary structural modeling of wild-type and mutant RhD proteins,and the structures of the two proteins were compared and analyzed to explore the reasons why mutations lead to weak serological manifestations.Results:The patient's genotype was identified as RHD*DV.5/RHD*01N.01 heterozygote,with the complete deletion of RHD genes on one chromosome,unable to express the D antigen.On the other chromosome,a G＞A mutation occurred at the 697th base of the 5th exon,resulting in a partial D phenotype.This mutation causes internal hydrogen bond changes at the 233 position of RhD protein,resulting in a change in the conformation of the protein,affecting binding to the corresponding antibody.Conclusion:The patient is a heterozygous mutant individual with RHD*DV.5/RHD*01N.01,exhibiting a partial D phenotype serologically.This variation is extremely rare and has been scarcely reported globally.

OBJECTIVE To investigate the protective effect and mechanism of saikosaponin C(SSC)on acute liver injury(ALI)in mice induced by carbon tetrachloride(CCl4)based on serum metabolomics.METHODS Forty mice were divided into blank group(water),model group(water),positive control drug group(Biphenyl diester drop pills,150 mg/kg),and SSC low-and high-dose groups(2.5,10 mg/kg)using the random number table method,with 8 mice in each group.They were given water/relevant drugs,once a day,for 7 consecutive days.One hour after the last administration,all mice were intraperitoneally injected with 0.2％CCl4 olive oil to induce ALI model,except for the blank group.After 17 hours of the modeling,the liver index of mice was calculated.The levels of aspartate aminotransferase(AST),alanine aminotransferase(ALT),lactate dehydrogenase(LDH),tumor necrosis factor-α(TNF-α),interleukin-6(IL-6),and IL-1β in serum of mice were detected.The histopathological changes of liver tissue were observed.Meanwhile,the serum metabolomics of mice were analyzed by liquid chromatography-mass spectrometry.RESULTS Compared with the blank group,the levels of liver index,ALT,AST,LDH,TNF-α,IL-6,and IL-1β in the model group were significantly increased(P＜0.01).Hepatocytes were edema,vacuolar degeneration,more necrosis,and a large number of inflammatory cells were infiltrated.Compared with the model group,liver index and serum index levels of mice were significantly decreased(P＜0.05 or P＜0.01),accompanied by marked improvement in histopathological damage to the liver tissue.The metabolomics results showed that compared with the model group,there were 63 up-regulated and 256 down-regulated differential metabolites in the serum of mice in the SSC high-dose group,including prostaglandin B2,20-hydroxy-leukotriene B4,5-hydroxy-L-tryptophan,7α-hydroxycholesterol,etc.;these metabolites were primarily involved in metabolic pathways such as arachidonic acid metabolism,5-hydroxytryptamine synapse,primary bile acid biosynthesis.CONCLUSIONS SSC exerts a protective effect against CCl4-induced ALI by down-regulating the level of key metabolites such as prostaglandin B2 and 20-hydroxy-leukotriene B4,and then ruducing metabolic pathways such as arachidonic acid metabolism,5-hydroxytryptamine synapse,and primary bile acid biosynthesis.

Patients suffering from nerve injury often experience exacerbated pain responses and complain of memory deficits. The dorsal hippocampus (dHPC), a well-defined region responsible for learning and memory, displays maladaptive plasticity upon injury, which is assumed to underlie pain hypersensitivity and cognitive deficits. However, much attention has thus far been paid to intracellular mechanisms of plasticity rather than extracellular alterations that might trigger and facilitate intracellular changes. Emerging evidence has shown that nerve injury alters the microarchitecture of the extracellular matrix (ECM) and decreases ECM rigidity in the dHPC. Despite this, it remains elusive which element of the ECM in the dHPC is affected and how it contributes to neuropathic pain and comorbid cognitive deficits. Laminin, a key element of the ECM, consists of α-, β-, and γ-chains and has been implicated in several pathophysiological processes. Here, we showed that peripheral nerve injury downregulates laminin β1 (LAMB1) in the dHPC. Silencing of hippocampal LAMB1 exacerbates pain sensitivity and induces cognitive dysfunction. Further mechanistic analysis revealed that loss of hippocampal LAMB1 causes dysregulated Src/NR2A signaling cascades via interaction with integrin β1, leading to decreased Ca²⁺ levels in pyramidal neurons, which in turn orchestrates structural and functional plasticity and eventually results in exaggerated pain responses and cognitive deficits. In this study, we shed new light on the functional capability of hippocampal ECM LAMB1 in the modulation of neuropathic pain and comorbid cognitive deficits, and reveal a mechanism that conveys extracellular alterations to intracellular plasticity. Moreover, we identified hippocampal LAMB1/integrin β1 signaling as a potential therapeutic target for the treatment of neuropathic pain and related memory loss.
