Objective: To investigate the potential of conventional cranial computed tomography (CT) in assessing the early neurological deterioration(END), long-term prognosis, and traditional Chinese medicine (TCM) syndrome elements during the acute phase in patients with acute ischemic stroke (AIS). Methods: This study included 101 patients with AIS onset within 24 h in the Emergency Department of Fangshan Hospital, Beijing University of Chinese Medicine, from November 2019 to May 2021. To investigate the correlation between the relevant characteristics of the first conventional cranial CT in patients with AIS onset within 24 h and END, 90 d prognosis, and initial syndrome elements, the presence or absence of END, the 90 d prognosis (non-disabling outcome or functionally independent outcome), and the establishment of syndrome elements (internal fire, phlegm-dampness, blood stasis, qi deficiency, yin deficiency) were used as dependent variables and grouping criteria. Results: This study included 61 males and 40 females, with an age of (64.43±10.56) years. The time from onset to conventional cranial CT examination was 3.50 (1.50, 9.75) h. Among the patients, there were 70 cases (69.3%) of mild AIS, 30 cases (29.7%) of moderate AIS, and one case (1.0%) of severe AIS. Fifteen patients (14.9%) received intravenous thrombolysis. Among the 101 patients, six syndrome elements were observed within 24 h of onset: internal wind in 101 cases (100.0%), internal fire in 58 cases (57.4%), phlegm-dampness in 60 cases (59.4%), blood stasis in 67 cases (66.3%), qi deficiency in 39 cases (38.6%), and yin deficiency in 23 cases (22.8%). The incidence of END was higher in patients with lesions in the contralateral cerebral hemisphere to the affected limb (32.9%) than in those without such lesions (10.7%), showing a strong positive correlation with END occurrence (OR=4.082, P = 0.026). The incidence of END was higher in patients with lesions in the basal ganglia region (33.3%) and the carotid system blood supply area (32.8%) than in those without lesions in the basal ganglia region (15.8%) and the carotid system territory (14.7%), showing moderate positive correlations with END occurrence (OR=2.667, P =0.047; OR=2.836, P=0.044). The proportion of non-disabling outcomes was lower among patients with white matter degeneration (30.8%) and lesions in the contralateral cerebral hemisphere to the affected limb (52.1%) than in those without white matter degeneration (63.6%) and without such lesions in the contralateral cerebral hemisphere to the affected limb (78.6%), both showing strong negative correlations with the occurrence of non-disabling outcomes (OR=0.254, P=0.034; OR=0.296, P=0.015). Similarly, the proportion of functionally independent outcomes was lower among individuals with white matter degeneration (30.8%) and lesions in the contralateral cerebral hemisphere to the affected limb (64.4%) than in those without white matter degeneration (77.3%) and without such lesions in the contralateral cerebral hemisphere to the affected limb (89.3%), both also showing strong negative correlations with the occurrence of functionally independent outcomes (OR=0.131, P=0.001; OR=0.217, P=0.014). The incidence rates of internal fire, blood stasis, and yin deficiency syndrome elements were 66.7%, 73.0%, and 30.2%, respectively, among patients with lesions in the basal ganglia region, compared to 42.1%, 55.3%, and 10.5% among those without lesions in this region. The presence of lesions in the basal ganglia region showed moderate to strong positive correlations with internal fire and yin deficiency syndrome elements (OR=2.750, P=0.016; OR=3.670, P=0.028). Patients with lesions in the centrum semiovale and corona radiata regions (66.7%) had a higher incidence of qi deficiency than those without lesions in this region (33.7%), showing a strong positive correlation with the occurrence of qi deficiency (OR=3.931, P=0.022). No CT characteristics were found to be correlated with phlegm-dampness syndrome elements. Conclusion The first cranial CT in patients with AIS has potential application value in predicting disease progression, assessing prognosis, and diagnosing syndromes, which can provide physicians with diagnostic and treatment decisions to improve the long-term prognosis of patients with AIS.

Objective:To investigate the intervention effect and active mechanism of traditional Chinese medicine Marsdenia tenacis-sima on colitis-associated colorectal cancer(CAC).Methods:High-resolution mass spectrometry and a precise mass number data-base were used to identify the chemical components of Marsdenia tenacissima,and network pharmacology methods were used to obtain the main active components and targets of Marsdenia tenacissima in the treatment of colorectal cancer(CRC)and analyze its mecha-nism of action against CRC.A mouse model of CAC was established,and then Marsdenia tenacissima was analyzed in terms of its effect on disease activity index(DAI),body mass,colorectal morphology,and serum levels of tumor necrosis factor-α(TNF-α)and interleu-kin-1β(IL-1β)in CAC mice.Furthermore,16S rDNA sequencing technique was used to assess the impact of Marsdenia tenacissima on the diversity of intestinal microbiota in mice.Results:A total of 50 components were identified by mass spectrometry,and 37 active components were identified by network pharmacology.Furthermore,313 targets related to CRC were identified.A total of 958 GO terms and 173 KEGG terms were obtained,among which inflammation,oxidative stress,and cancer pathways showed a relatively high de-gree of association with Marsdenia tenacissima.After modeling,the mice in each group had the manifestations such as diarrhea,bloody stool,prolapse of anus,and weight loss,and the model group had a significant increase in DAI score after each DSS cycle,while the Marsdenia tenacissima group had a significant reduction in DAI score of the model mice after the first,second,and third cycles(P=0.007,P<0.001,and P<0.001).In addition,compared with the model group,the Marsdenia tenacissima group had a significant in-crease in colorectal length,alleviation of intestinal swelling,a relatively intact structure of epithelial cells,a reduction in inflammatory cell infiltration,a significant increase in goblet cells,a reduction in atypical hyperplasia,and significant reductions in the levels of TNF-α and IL-6 in CAC mice(P<0.001 and 0.002).The Marsdenia tenacissima group had significant reductions in the abundance and diversity of intestinal microbiota,and compared with the model group,the Marsdenia tenacissima group had a significant reduction in the relative abundance of Bacteroides and significant increases in the relative abundances of Muribaculaceae and Clostridia-UCG-014(P=0.002 and 0.009).Conclusion:Marsdenia tenacissima exerts an intervention effect on colorectal cancer in CAC mice,possibly by regulating the pathways associated with inflammation and cancer and altering the diversity of intestinal microbiota.

Objective : To investigate the trends in incidence of malignant tumors in Yongkang City, Zhejiang Province from 2013 to 2019, so as to provide insights into formulation of the malignant tumor control strategy. Methods: Data pertaining to the incidence of malignant tumors from 2013 to 2019 were captured from the Zhejiang Chronic Disease Monitoring Information System. Based on the International Classification of Diseases 10th Revision (ICD-10) and data from the national population census, the constituent ratio, crude incidence and Chinese population-standardized incidence of malignant tumors were estimated, and the trends in incidence of malignant tumors were investigated using annual percent change (APC). Results: The annual mean crude incidence and Chinese population-standardized incidence of malignant tumors were 356.75/105 and 226.97/105, which both appeared an overall tendency towards a rise (APC=5.887% and 4.815%, both P<0.05). The crude incidence of malignant tumors appeared a tendency towards a rise among both men (APC=3.860%, P<0.05) and women (APC=8.534%, P<0.05) from 2013 to 2019, and the Chinese population-standardized incidence of malignant tumors appeared a tendency towards a rise among women (APC=8.392%, P<0.05). The largest increase in the crude incidence of malignant tumors was seen among women at ages of 15 to 44 years (APC=11.599%, P<0.05). In addition, the Chinese population-standardized incidence of lung cancer, colorectal cancer and thyroid cancer all showed a tendency towards a rise among men (all P<0.05), and the Chinese population-standardized incidence of lung cancer and thyroid cancer both appeared a tendency towards a rise among women (both P<0.05). Conclusions The incidence of malignant tumors showed a tendency towards a rise in Yongkang City from 2013 to 2019, and the elderly and young females are high-risk populations for malignant tumors. Lung cancer, thyroid cancer and colorectal cancer are cancers that should be given a high priority.

ObjectiveTo establish a set of single nucleotide polymorphisms (SNP) detection protocol for inbred rats based on multiplex PCR-ligase detection reaction (LDR). MethodsA total of 40 rats SNP sites were selected on chromosomes 1-20 and X of rats among 5 inbred strains of rats, and the 40 SNP sites were randomly divided into four groups. A genetic detection protocol for 4 groups of SNP in inbred rats based on multiplex PCR-LDR technology was constructed. 9 commonly used rat strains from two other domestic rat suppliers were detected by this protocol. Finally, the feasibility of this protocol was verified by comparing the amplification effects of different DNA polymerases by a third-party laboratory. ResultsWhen using the constructed SNP detection protocol for inbred rats to test 5 rat strains, all sites in each sample obtained good amplification results. The 9 commonly used rat strains from two other rat suppliers in china were also well amplified by this SNP detection protocol, and 40 SNPs were homozygous in each Inbred strain. The results of detection of the same rat DNA samples with three different DNA polymerases showed that the Multiplex PCR Kit, AmpliTaq Gold 360 DNA polymerase and Platinum II Taq hot start DNA polymerase had electrophoretic peaks of amplification products at all SNP sites in groups 1 to 3, and Platinum II Taq hot start DNA polymerase had one less electrophoretic peak of the amplification products at the SNP sites in group 4. In addition, inter-laboratory comparisons showed consistent results for the same amplification system. ConclusionBased on multiplex PCR-LDR technology, this study successfully established a SNP detection protocol for rats covering all autosomes and X chromosomes with the excellent stability and repeatability.
