ObjectiveTo construct a standardized diagnostic scale for Qi-Yin deficiency with blood stasis syndrome in diabetic macrovascular disease. MethodsLiterature related to Qi-Yin deficiency with blood stasis syndrome in diabetic macrovascular disease was retrieved from CNKI， VIP， and Wanfang databases. Diagnostic information from four diagnostic methods was extracted and standardized， with items having a frequency of ≥15 included in the item pool. A three-round Delphi expert consultation was conducted， screening items using support degree， mean score， rank sum， and coefficient of variation. Item weights were determined using analytic hierarchy process （AHP）， gactor analysis （FA）， and combined weighting method （CWM）. The optimal weighting method was selected by comparing the area under the receiver operating characteristic （ROC） curve （AUC）. The Youden index was calculated to establish the diagnostic cutoff value， which was proportionally scaled. ResultsA total of 102 studies were included. Thirty-five items were incorporated into the item pool. The authority coefficients for the three Delphi rounds were 0.82， 0.85， and 0.86， with coordination coefficients of 0.648， 0.538， and 0.506， respectively. Fifteen items were retained after screening. ROC curve analysis showed the AUC ranking as FA > CWM > AHP. The maximum Youden index was 0.814， corresponding to a diagnostic cutoff of 8.361 （scaled to 40 points）. The final scale adopted a structured diagnostic framework： the symptom dimension requires at least 2 items， and the tongue or pulse dimension requires at least 1 category. ConclusionThis study developed a standardized diagnostic scale for Qi-Yin deficiency with blood stasis syndrome in diabetic macrovascular disease. Core items were screened via the Delphi method， with factor analysis identified as the optimal weighting method through AUC comparison. The diagnostic threshold （40 points） and structured diagnostic framework provide a quantitatively clear， clinically practical tool.

ObjectiveThis study focused on the marketed Chinese patent medicines for the treatment of Functional Diarrhea （FDr） in China and their prescription characteristics， in order to provide support for the clinical application and research and development of anti-FDr Chinese patent medicines. MethodsCollect the information of Chinese patent medicines that have been marketed to treat FDr， use Microsoft Excel 2021 software to conduct preliminary data collation and statistical analysis， and use the ancient and modern medical record cloud platform （V2.3.9） to analyze the standardized Chinese patent medicine prescriptions from the aspects of drug nature and taste， medication characteristics and prescription rules. Results147 kinds of FDr Chinese patent medicines were included in this study. There are a total of 40 varieties of FDr Chinese patent medicines suitable for children； The distribution of dosage forms is mainly pills， tablets， and capsules. 110 prescriptions were screened， among which the proportion of Chinese patent medicines for the treatment of spleen deficiency syndrome was the highest； The top three drug use frequency were licorice， Atractylodes macrocephala， and Poria cocos； The medicinal properties are mainly warm and flat， and the medicinal taste is mostly pungent， sweet and bitter， and most of them belong to the two meridians of the spleen and stomach； The association rules analysis obtains 20 strong association pairing sets； Three drug combinations were obtained by cluster analysis. ConclusionFDr Chinese patent medicine shows unique value in clinical application， especially in the field of children. However， there are still problems such as strong professionalism in the indication expression of drug instructions， limited coverage of the medical insurance catalog， and lack of high-level evidence-based medicine and pharmacoeconomic evidence. To this end， in the future， efforts should be made to build a multi-level evidence-based evidence system， improve medication compliance， and deepen research on syndrome-based medication laws， so as to enhance the clinical application value and scientific connotation of FDr Chinese patent medicines.

Obesity has become one of the important factors affecting the entire management process of liver transplantation. Its impact is not only reflected in the increased risk of liver steatosis and ischemia-reperfusion injury in the donor, but also involves the increased technical difficulty during the perioperative period for the recipient, the increase in postoperative metabolic complications and poorer long-term prognosis. This article, based on recent relevant studies, reviews aspects such as the utilization of obese donors, the characteristics of adult and pediatric recipients, pre-transplant risk assessment and weight loss intervention, and post-transplant weight and metabolic management. Current evidence suggests that simply judging transplantation risks based on body mass index has limitations. Analysis of body composition, assessment of cardiovascular function and identification of sarcopenic obesity are more clinically valuable. For obese liver transplant recipients, in a multidisciplinary collaboration framework, emphasis should be placed on individualized screening, perioperative optimization and long-term follow-up management to improve the outcomes of the graft and the recipient.

Objective To investigate the association between single nucleotide polymorphisms (SNPs) in the nicotinamide adenine dinucleotide phosphate-oxidase (NOX) 2 and NOX4 genes and susceptibility to noise-induced hearing loss (NIHL). Methods A total of 439 noise-exposed workers were recruited using a convenience sampling method. Based on pure-tone air conduction hearing threshold tests, participants were categorized into normal hearing, mild hearing loss, and moderate hearing loss groups, with 147, 154, 138 individuals, respectively. Peripheral venous blood samples of the workers were collected for DNA extraction. Genotyping of nine SNPs loci in NOX2 and NOX4 genes was performed using multiplex polymerase chain reaction, single-base extension, and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry. Results A total of seven of the nine SNPs loci conformed to Hardy-Weinberg equilibrium among the workers in the normal hearing group (all P>0.05). There was no significant difference in the genotype distribution or allele frequencies for these seven SNPs loci among workers in these three groups (all P>0.05). Ordinal logistic regression analysis showed that, after adjusting for confounders including age, sex, cumulative noise exposure, smoking, alcohol consumption, and earplug use, individuals carrying the GG genotype at rs200522762 had a lower risk of NIHL compared with those carrying the TT genotype under the codominant model (P<0.05). In the recessive model, individuals carrying the GG genotype at the rs200522762 locus had a lower risk than those carrying the GT+TT genotypes (P<0.05). Polymorphisms at the other six SNPs loci were not associated with NIHL risk (all P>0.05). Conclusion The NOX4 rs200522762 polymorphism is associated with susceptibility to NIHL.

Objective:To investigate the effect and mechanism of lycium barbarum polysaccharide(LBP)on lipopolysaccharide(LPS)-induced inflammatory response of NLRP3 inflammasome in BV2 microglial cells.Methods:BV2 microglial cells were routinely cultured.CCK-8 assay was used to detect the effect of different concentrations(0.5,1,1.5,2 g/L)LBP on cell activity.Cells were di-vided into three groups:control group,LPS group and LBP+LPS group.Effect of LBP on LPS-induced cell activity was detected by CCK-8 method;RT-qPCR and immunofluorescence assay were used to detect NLRP3,ASC,Caspase-1,IL-18 and IL-1β expressions.Western blot was used to detect expressions of NLRP3,ASC,Caspase-1,TLR4,MyD88,NF-κB p65,IL-18,IL-1β and TNF-α pro-teins.Results:CCK-8 assay showed that 1 g/L LBP was the most applicable.Compared with control group,cell viability in LPS group was decreased;RT-qPCR,immunofluorescence and Western blot results showed that fluorescence intensity,mRNA and protein expres-sions of NLRP3,ASC,Caspase-1,IL-18 and IL-1β were increased in LPS group.Western blot results showed that TLR4,MyD88,NF-κB p65 and TNF-α protein expressions were increased in LPS group.After LBP treatment,cell viability was increased;expres-sions of NLRP3,ASC,Caspase-1,NF-κB p65,TLR4,MyD88,IL-18,IL-1β and TNF-α were decreased.Conclusion:LBP may in-hibit LPS-induced NLRP3 inflammatory vesicles in BV2 cells via TLR4/MyD88/NF-κB signaling pathway.

Objective:To explore the clinical characteristics and risk factors for the progression of severe scrub typhus in children.Methods:Clinical data, laboratory and auxiliary examination results, treatment and prognosis data of children with scrub typhus admitted to Xiamen Children's Hospital from July 2014 to March 2024 were collected. The clinical characteristics of scrub typhus in children were analyzed, and the study subjects were divided into severe group and mild group according to their condition. The relevant risk factors for progression to severe cases were analyzed.Results:A total of 42 cases were included, with 34 cases (80.95%) in the mild group and 8 cases (19.05%) in the severe group. All patients(100%) had fever, with the highest incidence of eschar or ulceration (95.24%), followed by lymphadenopathy and splenomegaly. All 42 patients improved or recovered after treatment with azithromycin or doxycycline, with no deaths reported. Compared with the mild group，the severe group had a higher incidence of cough, lymphadenopathy，and hepatomegaly, with statistically significant differences( P<0.05). Compared with the mild group, the severe group showed a decrease in hemoglobin(Hb), platelet, and fibrinogen(Fib) levels, while serum C-reactive protein(CRP), procalcitonin, aspartate aminotransferase, creatine kinase MB, and lactate dehydrogenase (LDH) levels increased, with statistically significant differences( P<0.05). Multivariate Tobit model analysis showed that a decrease in Hb ( OR -0.006，95% CI -0.012-0.000， P<0.05), an increase in CRP ( OR 2.72，95% CI 0.001-0.008， P=0.010), an increase in LDH ( OR 1.76，95% CI 0.000-0.000， P=0.027), and a decrease in Fib ( OR -3.78，95% CI -0.309-0.093， P=0.001) were risk factors for scrub typhus progressing to severe cases. Conclusion:During the epidemic season of scrub typhus, fever accompanied by eschar or ulceration, along with splenomegaly and lymphadenopath aids in the diagnosis of scrub typhus. Decreased Hb and Fib, as well as elevated CRP and LDH, are risk factors for the development of severe scrub typhus in children.

Three soil conditioners were prepared from granulated food waste and decomposed cattle manure combined with desulfurization gypsum, coal gangue, and maifanite, respectively. Field trials were conducted in the saline field growing Cabernet Sauvignon. The effects of soil conditioners on rhizospheric bacterial communities were studied, with the aim of providing a scientific basis for soil amelioration and restoration. Five treatments were designed, including the control (T1), conventional fertilization (T2), reduced chemical fertilization+organic matter-based soil conditioner with calcium additives (T3), reduced chemical fertilization+organic matter-based soil conditioner with silica additives (T4), and reduced chemical fertilization+organic matter-based soil conditioner with magnesium additives (T5), each with three replications. The results indicated that soil conditioners improved the rhizospheric nutrients, yield, and quality of grape (P<0.05), increased relative abundance of Proteobacteria by 17.32%-23.37%, decreased relative abundance of unidentified_Bacteria and Acidobacteriota by 4.22%-28.42% and 20.88%-35.81%, respectively. The bacterial community composition and diversity were different between treatments. Function analysis showed that the expression levels of the genes involved in chromosome and protein synthesis, mRNA biosynthesis, and glyoxylate and dicarboxylate metabolism were up-regulated in the treatments with soil conditioners. The correlation analysis revealed that multiple environmental factors affected the alpha diversity of rhizospheric bacterial communities, and some bacterial taxa were closely related to the grape yield and quality. It is concluded that soil conditioners can effectively alter rhizosphere nutrient levels and bacterial community structures and functions. T5 treatment outperforms other treatments in improving the physico-chemical and biological characteristics of rhizosphere, and the yield, and quality of grape. It has potential for application, and provides an important basis for development of new-type soil conditioners.
