To understand the pathogenicity and drug resistance of swine-derived E.coli and its bio-logical characteristics in some areas in Hebei,E.coli was isolated and identified from diarrheal fe-ces of piglets collected from swine farms,and the isolated strains were subjected to drug sensitivity test,detection of the ability to form biofilm,pathogenicity test,virulence gene test,drug resistance gene test,and identification of phylogenetic subgroups.The results showed that a total of 35 patho-genic E.coli strains were isolated from the feces of diarrheic piglets,and most of the isolates were multidrug-resistant,and were resistant to at least three antibiotics,including amoxicillin(88.57％),ampicillin(88.57％),doxycycline(88.75％),sulfisoxazole(77.17％),lincomycin(100％),and chloramphenicol(100％);the isolates were severely resistant.The isolates all carried virulence genes,with a total of five virulence genes detected,namely,EAST1(77.14％),eaeA(17.14％),stx2e(5.71％),LT(2.86％),and STb(2.86％),and the isolates also carried multi-re-sistance genes,with a total of five virulence genes detected,namely,bla TEM-1(65.71％),bla CTX-M(20.00％),tetA(82.86％),tetB(14.29％),aadA2(17.14％),aac(6')-Ib(14.29％),qnrS(17.14％),sul 1(40.00％),sul2(34.29％),and floR(60.00％);the phylogenetic grouping showed that the isolates had a high proportion of group B1 and group A;and all 35 isolates showed differ-ent pathogenicity after infection of mice.This study provides a reference for the selection of effec-tive therapeutic drugs and the development of prevention and control programs for swine-origin pathogenic E.coli in Hebei Province.

Objective To explore the distribution characteristics of common TCM syndromes in colorectal cancer;To provide a basis for standardized research on syndrome of colorectal cancer.Methods The literature related to TCM syndromes of colorectal cancer was retrieved from CNKI,Wanfang Data,VIP and SinoMed.Information on syndrome types and symptoms was extracted to establish a traditional Chinese medicine syndrome database for colorectal cancer.Frequency statistics were used to analyze distribution of colorectal cancer syndrome types and their symptom characteristics.Lantern 5.0 software was used to establish a latent structure model based on the LTM-EAS algorithm,and factor analysis and systematic clustering analysis were conducted using SPSS 27.0 software to infer potential patterns.Based on the results of comprehensive frequency statistics,systematic clustering and latent structure analysis,common TCM syndrome types and symptom characteristics of colorectal cancer were obtained.Results A total of 929 articles were included,totaling 2 465 syndrome items,involving 97 syndrome types,with high frequency of qi-blood deficiency syndrome,dampness and heat accumulation syndrome,spleen-kidney yang deficiency syndrome,etc.,and 281 symptoms,including abdominal distension,anorexia,abdominal pain and mental fatigue,etc.The latent structure analysis obtained 23 hidden variables,and 8 common syndromes were obtained according to professional knowledge.Factor analysis obtained 17 common factors,and further systematic cluster analysis inferred 9 potential syndrome types.Conclusion Common syndrome of colorectal cancer can be divided into 9 types,which are dampness and heat accumulation syndrome,blood stasis toxicity internal obstruction syndrome,qi stagnation and blood stasis syndrome,dampness and heat stasis toxicity syndrome,spleen deficiency and phlegm-dampness syndrome,spleen qi deficiency syndrome,qi and blood deficiency syndrome,liver-kidney yin deficiency syndrome,and spleen-kidney yang deficiency syndrome.The symptom characteristics of each syndrome are significant,which can provide reference for clinical differentiation and lay foundation for standardized research on syndrome.

Malignant tumors represent a significant contributor to the increasing global burden of disease.Contemporary medical therapies often face challenges such as high recurrence rates and considerable adverse effects,making the exploration of more efficient and safer treatment strategies for cancer patients a current research priority.Traditional Chinese Medicine(TCM)has demonstrated unique value in oncology,exhibiting comprehensive advantages including multi-target effects,diverse active components,and low drug resistance,particularly in enhancing efficacy,reducing toxicity,improving prognosis,and elevating patients'quality of life.Through a literature review and based on the Cancer Toxin pathogenesis theory,this article systematically elaborates on the antitumor effects and underlying mechanisms of Qi-regulating and detoxifying Chinese medicines,aiming to provide new insights and scientific evidence for the TCM-based diagnosis and treatment of malignant tumors.

ObjectiveTo evaluate the efficacy and safety of spleen-strengthening therapy in the treatment of postoperative colorectal adenoma. MethodRandomized controlled trials （RCTs） of spleen-strengthening therapy for postoperative colorectal adenoma published in the databases of China National Knowledge Infrastructure （CNKI）， Wanfang Data， VIP， SinoMed， PubMed， Cochrane Library， Embase， Web of Science， and Clinical Trials registry center from database inception to February， 2024 were retrieved and selected based on inclusion and exclusion criteria. The included RCTs were subjected to Meta-analysis using RevMan 5.3 software. ResultA total of 29 articles were included， involving 2 935 patients， with 1 462 in the experimental group and 1，473 in the control group. The Meta-analysis results showed that compared with conventional Western medical treatment alone， the experimental group that combined the spleen-strengthening therapy with conventional Western treatment had a significantly lower recurrence rate at six months post-surgery ［relative risk （RR）=0.45， 95% confidence interval （CI） ［0.37， 0.53］， P<0.000 01］， and at one year post-surgery （RR=0.54， 95%CI ［0.47， 0.63］， P<0.000 01）. Additionally， the experimental group showed significant improvement in clinical symptoms （RR=1.28，95%CI ［1.17，1.40］， P<0.000 01） and more pronounced effects in suppressing inflammatory factors， with no serious adverse reactions observed. The differences were all statistically significant. The analysis of the Chinese medicines used in the included articles revealed 28 prescriptions with 99 different drugs used 369 times in total. The most frequently used drug was Atractylodis Macrocephalae Rhizoma， followed by Codonopsis Radix， Poria， Glycyrrhizae Radix et Rhizoma， and Citri Reticulatae Pericarpium. Furthermore， correlation analysis showed that spleen-strengthening drugs were often used in combination with heat-clearing and toxin-removing drugs， qi-regulating drugs， and blood-activating drugs such as Hedyotidis Diffusae Herba， Citri Reticulatae Pericarpium， and Curcumae Rhizoma. ConclusionThe spleen-strengthening therapy demonstrates good clinical efficacy and high safety for patients with postoperative colorectal adenoma. However， due to the limitations in the quantity and quality of the included RCTs， more high-quality clinical trials are needed to verify these conclusions.

OBJECTIVE: To investigate the infection of leptospirosa of host animals and the immune level of healthy population in flood areas. METHODS: Korth culture was used to culture leptospira for rodent kidney and oxen urine sample. The serogroups of leptospira and leptospira antibody were tested by microscopic agglutination test (MAT). RESULTS: In flood regions, draw-near-flood region, and new migration region, rodent density was 6.95%, 6.28%, and 8.67%, respectively. The positive rates of rodent with leptospira was 4.63%, 1.35%, and 3.13%, respectively. Leptospira positive rates of oxen urine were 5.88%, 5.98%, and 1.75%, respectively. The main serogroup of leptospira was Icterhamorrhagic and Canicola serogroup. The positive rates of leptospirosa antibody in healthy population was 45.91%, 62.30%, and 58.67%in these 3 regions respectively, which was significantly higher than the average level in China. The dominant serogroups of leptospira in health population were icterhamorrhagic, autumnalis, canicola, pomona and bataviae. The positive rate of antibody had no difference among different age groups. CONCLUSION The main host animals are rodents and oxen infected with leptospira and the positive rate of leptospira antibody is high in healthy population in the study area. The dominant serogroups in host animals are similar to that in healthy population, which is mostly icterhaemorrhagic.
