ObjectiveTo compare the mosquito capture efficacy of the BG-trap method and the light trap method, and to explore the precisely applicable scenarios for the two monitoring approaches. MethodsFrom May to October 2024, one BG-trap and one light trap were placed at eight monitoring sites, with a distance of over 10 meters between the two traps at each site. Surveillance was performed twice monthly to compare the two surveillance methods in terms of mosquito species composition, the proportional distribution of female mosquitoes across different habitats, and seasonal fluctuations in mosquito density. ResultsThere were statistically significant differences in mosquito species composition (χ²=60.61, P<0.001) and female mosquito species composition (χ²=37.12, P<0.001) between the BG-trap method and the light trap method, with the BG-trap method capturing a higher proportion of Aedes albopictus than the light trap method. The average density of mosquitoes monitored by the BG-trap method [13.36 mosquitoes·(trap·night)^-1] was higher than that monitored by the light trap method[4.70 mosquitoes·(trap·night)^-1]. There was statistically significant difference (t=6.70, P<0.001) for the mosquito density between the two methods, and there was a significant positive correlation (r=0.909, P<0.001) for the mosquito density indices between the two methods. The average density of female mosquitoes monitored by the BG-trap method [8.18 mosquitoes·(trap·night)^-1] was higher than that monitored by light trap method [3.36 mosquitoes·(trap·night)^-1]. There was statistically significant difference (t=6.00, P<0.001) for the female mosquito density between the two methods, and there was a significant positive correlation (r=0.929, P<0.001) for the female mosquito density indices between the two methods. In the four different habitats, the constituent ratio of mosquitoes and female mosquitoes monitored by the BG-trap method in descending order were urban residential area (43.80% and 40.25%), rural farm households (35.55% and 38.60%), hospital (12.70% and 12.87%), and park (7.95% and 8.28%), while the constituent ratio of mosquitoes and female mosquitoes monitored by the light trap method in descending order were rural farm households (34.37% and 43.34%), hospital (33.26% and 30.03%), park (17.96% and 15.17%), and urban residential area (14.41% and 11.46%). In different habitats, there were statistically significant differences for mosquito composition ratios (χ²=189.64, P<0.001) and female mosquito composition ratios (χ²=109.15, P<0.001) between the two monitoring methods. ConclusionThe BG-trap method offers advantages such as simple operation, compact equipment, and high efficiency, with a higher trapping rate for Aedes albopictus compared to the light trap method. In routine monitoring, the BG-trap method can serve as a supplement to the light trap method, while for emergency monitoring of Aedes albopictus in dengue fever outbreak areas and mosquito collection efforts, the BG-trap method is more effective than the light trap method.

ObjectiveTo observe the clinical efficacy of Tangshen Dihuang decoction in treating diabetic kidney disease （DKD） with liver-kidney Yin deficiency and blood stasis syndrome and its impact on gut microbiota. MethodsA randomized controlled clinical trial was conducted， in which 102 DKD patients with liver-kidney Yin deficiency and blood stasis syndrome were randomly assigned to the Tangshen Dihuang decoction group and the control group. Each group consisted of 51 cases， and the treatment period was 3 months. The primary efficacy indicators included urinary albumin-to-creatinine ratio （UACR）， fasting blood glucose （FBG）， 2-hour postprandial blood glucose （2 hPBG）， glycated hemoglobin （HbA₁C）， serum creatinine （SCr）， blood urea nitrogen （BUN）， angiotensinⅡ （AngⅡ）， serum cystatin C （Cys-C）， urinary N-acetyl-β-D-glucosaminidase （NAG）， urinary β₂-microglobulin （Uβ₂-MB）， traditional Chinese medicine （TCM） symptom scores， and gut microbiota. ResultsAfter treatment， the total response rate in the Tangshen Dihuang decoction was 87.23% （41/47）， which was higher than that （69.57%， 32/46） in the control group （Z=4.30， P<0.05）. After treatment， the TCM symptom scores decreased in both groups （P<0.01） and were lower in the Tangshen Dihuang decoction group than in the control group （P<0.01）. After treatment， the control group showed decreases in UACR， Uβ₂-MG， AngⅡ， and FBG （P<0.05） as well as 2 hPBG and HbA₁C （P<0.01）， and no significant differences in BUN， Cys-C， eGFR， SCr， and NAG. The Tangshen Dihuang decoction group showed increased eGFR （P<0.05）， declined levels of UACR， BUN， Cys-C， Uβ₂-MB， AngⅡ， FBG， 2 hPBG， NAG， and HbA₁C （P<0.01）， and no significant difference in SCr. The Tangshen Dihuang decoction group had lower BUN （P<0.05）， Cys-C （P<0.05）， AngⅡ （P<0.05）， 2 hPBG （P<0.05）， Uβ₂-MG （P<0.01）， and NAG （P<0.01） and higher eGFR level （P<0.05） than the control group. After treatment， the control group showed declines in Shannon， Observed_species， and Chao1 indices （P<0.05）. The samples from both groups showed statistically significant differences in the principal coordinates analysis （PCoA） plot based on Anosim analysis （P<0.05）. After treatment， the Tangshen Dihuang decoction group showed decreased relative abundance of Actinobacteria （P<0.05）. Moreover， the relative abundance of Actinobacteria was significantly lower in the Tangshen Dihuang decoction group than in the control group （P<0.05）. At the genus level， the control group showed decreased relative abundance of Bifidobacterium （P<0.05）， and the Tangshen Dihuang decoction group presented increased relative abundance of Bifidobacterium and Blautia_A （P<0.05）. After treatment， the Tangshen Dihuang decoction group had higher relative abundance of Bifidobacterium than the control group （P<0.01）. ConclusionTangshen Dihuang decoction has a significant therapeutic effect on DKD patients with liver-kidney Yin deficiency and blood stasis syndrome. It can markedly relieve clinical symptoms and reduce proteinuria and postprandial blood glucose by antagonizing the local renin-angiotensin system （RAS） and alleviating gut microbiota dysbiosis.

ObjectiveTo investigate the effects of lectin-like oxidized low-density lipoprotein receptor-1 （LOX-1） gene G501C on brain structure and cognitive function in patients with white matter hyperintensities （WMH）. MethodsA total of 118 patients with WMH were enrolled. All participants underwent T1-weighted and T2-fluid-attenuated inversion recovery （T2-FLAIR） MRI to assess gray matter structure and WMH burden， and completed the mini-mental state examination （MMSE） and Montreal cognitive assessment （MoCA）. Partial correlation and mediation analyses were performed to explore the impact of LOX-1 polymorphism on cognitive function. ResultsParticipants were divided into GG+GC group （n = 35） and CC group （n = 83）. The GG+GC group showed lower MMSE and MoCA scores （MMSE： P=0.003； MOCA： P=0.015）， as well as greater WMH burden （all P0.001）， compared with the CC group. Voxel-based morphometry （VBM） analysis revealed reduced left thalamic volume in the GG+GC group， which was correlated with cognitive scores （all P0.05）. Subregional thalamic analysis further showed volume reductions in the lateral， ventral， medial， and pulvinar thalamic regions （all P0.05） in the GG+GC group， all positively associated with cognitive performance （all P0.05）. Mediation analyses indicated that volumes of the medial and pulvinar thalamic regions mediated the association between genotype and cognitive function （MMSE， MoCA）， and that WMH volume mediated the effect on MoCA scores. ConclusionThe LOX-1 G501C polymorphism may indirectly affect cognitive function by influencing specific thalamic subregional volumes and white matter damage， suggesting a potential mediating role of thalamic structures between genetic background and cognitive impairment.

ObjectiveTo address abnormal foam formation during liquid fermentation of Trichoderma reesei(T. reesei) for cellulase production through process optimization.MethodsUsing quadruple fermentation tank, the process was optimized through four key parameters: medium composition, seed source preparation, feeding rate and feeding methodology. Different feeding strategies were evaluated, including time-sequence feeding, dissolved oxygen(DO) process value(PV)-linked feeding, and PID algorithm-controlled user defined function(UDF) feeding. The effects of coarse wheat bran supplementation and seed culture sources(plate vs. shake flask) on the fermentation process were also examined. Cellulase activity and biomass accumulation were monitored throughout the fermentation process.ResultsBoth reduced feeding rate and coarse wheat bran supplementation effectively decreased foam formation during protein expression, preventing abnormal foaming and overflow phenomena. The PID algorithm-controlled feeding strategy enhanced microbial growth, achieving a maximum biomass of 442. 9 g/L at 145 h. Shake flask-derived seed cultures demonstrated superior enzyme production compared to plate-derived seeds, maintaining higher enzyme activity levels after 66 h of fermentation. The combination of coarse wheat bran supplementation, time-sequence feeding strategy(sequence 1), and shake flask-derived seed culture promoted optimal cellulase accumulation, reaching an enzyme activity of 60. 096 U/mL at 145 h.ConclusionAn optimized fermentation process for T.reesei was developed, which effectively controls foam formation while maintaining high enzyme productivity.The findings provide new solutions for addressing foam-related issues in T. reesei liquid fermentation and offer valuable data support for scaling up cellulase production.

Objective It investigates the current status of negative defensive medical behavior tendencies among medical students and explores influencing factors,aiming to provide evidence for improving medical students' propensity for negative defensive medical practices.Methods In February 2023,a cluster sampling approach was employed to recruit 297 medical students from a medical college-affiliated hospital in Province H.Descriptive statistics,chi-square tests,and correlation analyses were conducted to assess negative defensive medical behavior tendencies.Structural equation modeling(SEM)was utilized to explore multidimensional influencing factors.Results 45％of medical students demonstrated high-level negative defensive medical behavior tendencies.Statistically significant differences were observed between genders(x2=5.569,P＜0.05)and only-child/non-only-child groups(x2=6.104,P＜0.05).Positive correlations were identified between negative defensive medical behaviors and role stress(r=0.217,P＜0.01),negative organizational environment evaluation(r=0.395,P＜0.01),and negative social environment evaluation(r=0.405,P＜0.01).Only-child status was confirmed as an influencing factor(β=-0.123,P=0.036).Negative organizational environment evaluation(β=0.504,P＜0.001)and negative social environment evaluation(β=0.193,P=0.039)showed significant positive effects.Conclusion Immediate interventions-including role-specific risk allocation,organizational ecosystem reconstruction,and social environment governance-require urgent implementation to address early-stage behavioral deviance,counteract the solidification of defensive medical thinking patterns,and reduce predispositions toward negative professional behaviors among medical trainees.

Objective:To investigate the impact of postoperative complications on adverse outcomes following curative-intent resection for gallbladder cancer (GBC).Methods:The multi-center real-world study was conducted. The clinicopathological data of 629 patients with GBC, who were admitted to 14 medical centers including The First Affiliated Hospital of Army Medical University from the national multicenter database of Biliary Surgery Group of Elite Group of Chinese Journal of Digestive Surgery, from April 2020 to April 2024 were collected. There were 225 males and 404 females, aged (64±10)years. Patients underwent open curative-intent resection for GBC. Observation indicators: (1)surgery, postoperative complica-tions and adverse outcomes; (2) analysis of risk factors affecting postoperative adverse outcomes in patients and population attributable fraction (PAF). Missing data in predictor variables were addressed using multiple imputation with chained equations, while cases with missing outcome variables were addressed using the "multiple imputation then deletion (MID)" strategy. The severity of multicollinearity among independent variables was assessed using the variance inflation factor (VIF) test. Multivariable possion regression models with log link and robust error variance were construc-ted incorporating restricted cubic splines (3 knots) to address nonlinear relationships in continuous variables, calculating adjusted relative risk ( RR) with corresponding 95% confidence interval ( CI). Adjusted PAF was calculated for each imputed dataset using the AF package of R software, with subsequent pooling performed according to Rubin's rules. Results:(1) Surgery, postoperative complications and adverse outcomes. All 629 patients underwent curative-intent resection for GBC, of which 143 cases had postoperative complications, including 68 cases of intra-abdominal ascites, 39 cases of pulmonary infection, 21 cases of bile leakage, 12 cases of intra-abdominal hemorrhage, 11 cases of liver failure, 10 cases of pan-creatic fistula, 10 cases of wound infection, 10 cases of gastroparesis, 7 cases of cholangitis, 7 cases of sepsis. The same patient could have more than one kind of complication. Of 629 patients, there were 19 cases of postoperative 90-day death and 11 cases of missing data, 42 cases with post-operative 90-day reoperation and 7 cases with missing data, 44 cases with postoperative 90-day readmission and 3 cases with missing data, 155 cases with prolonged postoperative hospital stay and 3 cases with missing data. (2) Analysis of risk factors affecting the postoperative adverse outcomes in patients and PAF. Results of multivariate analysis showed that pulmonary infection and liver failure were independent risk factors for postoperative 90-day mortality ( RR=3.74, 12.15, 95% CI as 1.18-11.83, 1.98-74.48, P<0.05). Pulmonary infection demons-trated the highest PAF as 4.61% (95% CI as 3.94%-5.28%, P<0.05). Intra-abdominal ascites, pulmonary infection, bile leakage, and intra-abdominal hemorrhage were independent risk factors for post-operative 90-day reoperation ( RR=4.80, 3.62, 3.46, 4.99, 95% CI as 2.49-9.26, 1.42-9.21, 1.34-8.92, 1.55-16.06, P<0.05). Intra-abdominal ascites demonstrated the highest PAF as 8.65% (95% CI as 8.22%-9.08%, P<0.05). Intra-abdominal ascites, bile leakage, and liver failure were independent risk factors for postoperative 90-day readmission ( RR=6.20, 3.33, 14.33, 95% CI as 3.21-11.95, 1.33-8.35, 3.72-55.28, P<0.05). Intra-abdominal ascites demonstrated the highest PAF as 9.11% (95% CI as 8.85%-9.37%, P<0.05). Intra-abdominal ascites, pulmonary infection, bile leakage, liver failure, and wound infection were independent risk factors for prolonged postoperative hospital stay ( RR=2.29, 2.21, 2.26, 2.14, 3.35, 95% CI as 1.63-3.23, 1.41-3.46, 1.32-3.86, 1.11-4.13, 1.70-6.60, P<0.05). Intra-abdominal ascites demonstrated the highest PAF as 6.03% (95% CI as 5.71%-6.35%, P<0.05). Conclusion:Pulmonary infection is the most significant risk factor for postoperative 90-day mortality after curative-intent resection for GBC, while intra-abdominal ascites is the most significant risk factor for postoperative 90-day reoperation, postoperative 90-day readmission, and prolonged postoperative hospital stay.

Objective A non-targeted metabolomics analysis of vitreous fluid from patients with proliferative diabetic retinopathy(PDR)is conducted to explore the"metabolic map"of PDR.This approach aims to deepen the understanding of the disease,identify potential biomarkers.Methods From 35 PDR patients and 30 fresh rhegmatogenous retinal de-tachment(RRD)patients,10 PDR patients with vitreoretinal abnormal adhesions were selected as the experimental group(PDR group),and 10 fresh RRD patients were chosen as the control group(RRD group).Using ultra-high-performance liq-uid chromatography-mass spectrometry non-targeted metabolomics technology,the metabolic profiles of vitreous fluid were analyzed to obtain metabolic spectra.One-dimensional and multidimensional statistical methods were used to analyze the differences in metabolites and metabolic pathways between the PDR and RRD groups.Results A total of 165 differential metabolites were identified in the vitreous humor samples of patients in the PDR and RRD groups,these differential metab-olites were significantly enriched in 21 metabolic pathways(P＜0.05),Among these pathways,those with at least 5 differ-ential metabolites include:methionine and cysteine metabolism;glycine,serine,and threonine metabolism;ascorbic acid and aldose metabolism;amino acid biosynthesis;and central carbon metabolism in cancer.Pyruvate,serine,D-2-phospho-glycerate,threonine,phosphoserine,and high serine are present in multiple metabolic pathways,the areas under the curve are 0.96,0.82,0.85,0.78,0.40,and 0.31,respectively.Conclusion There are 21 significantly different metabolic pathways between PDR and RRD patients.Pyruvate stands out in multiple pathways,potentially serving as a biomarker for PDR diagnosis.

Objective To investigate the risk factors of secondary traumatic coagulopathy in patients with traffic trauma.Methods A total of 122 patients with traffic trauma in Department of Emergency Surgery,the First Affiliated Hospital of Anhui Medical University(Dongcheng Hospital)from April 2022 to March 2023 were retrospectively collected.Patients were divided into the occurrence group(n=30)and the non-occurrence group(n=92).Body temperature,acidosis,hematoma enlargement after head CT examination,Glasgow coma score(GCS),trauma severity score(ISS),platelet count(PLT)and hemoglobin(Hb)at admission were collected and compared between the two groups.Multivariate Logistic regression was used to analyze risk factors of secondary traumatic coagulopathy in traffic trauma patients,and receiver operating characteristic(ROC)curve was used to analyze the predictive value of related factors for secondary traumatic coagulopathy.Results The body temperature,GCS,PLT and Hb in the occurrence group were lower than those in the non-occurrence group,while the ISS,incidence of acidosis and the incidence of increased hematoma after CT examination were higher than those in the non-occurrence group(all P<0.05).Multivariate Logistic regression analysis showed that low GCS,low Hb level,high ISS,acidosis and increased hematoma after head CT examination were risk factors at admission(P<0.05).The area under ROC curve(AUC)of the five factors combined for secondary traumatic coagulopathy in traffic trauma patients was 0.963,sensitivity was 83.3%and specificity was 96.7%.Conclusion Decreased GCS and Hb on admission,high ISS,acidosis and increased hematoma during head CT review are risk factors for secondary traumatic cotting disorder in traffic trauma patients,and the combination of these factors has high predictive value.

The aim of this study is to establish an gene editing method of Mesomycoplasma hyo-pneumoniae(Mhp)based on the homologous recombination principle.The restriction enzyme di-gestion and ligation method combined with gene synthesis were used to construct a shuttle plasmid to achieve replication in both Mhp and Escherichia coli(E.coli).The pGEM?-T vector was used as the skeleton.The oriC sequence of Mhp which can achieve the replication of the plasmid in Mhp was inserted into the vector.Sequences of the Spiroplasma promoter and puromycin resistance gene were then inserted into the above constructed plasmid to screen recombinant clones.The up-stream and downstream homologous arms of p97 were constructed to initiate homologous recombination.The recA gene of E.coli is inserted to improve the efficiency of homologous recom-bination.The obtained shuttle plasmid was then delivered into Mhp by electro-transformation or chemical transformation.A shuttle plasmid,pGEM?-Mhp-oriC-p 97,which can replicate in both Mhp and E.coli was constructed.With the transformation of this plasmid,the carried puromycin gene and recA gene can be expressed,the p97 gene can be edited.Finally,the genetically unstable p97 gene mutant was initially obtained.In this study,a tool for Mhp gene editing based on the principle of homologous recombination was established,which laid a foundation for the develop-ment of tools for studying the pathogenesis of Mhp.
