Objective:To explore the application value of radiomics models based on MRI of vertebrae and paravertebral muscles in identifying potential vertebral fragility fracture risk in osteoporosis and osteopenia.Methods:This cross-sectional study collected data from patients who underwent both dual-energy X-ray absorptiometry (DXA) and lumbar MRI at the Third Affiliated Hospital of Southern Medical University between January 2014 and December 2023,retrospectively. Based on DXA results, patients were categorized into osteoporosis group ( n=302) and osteopenia group ( n=264), with fracture and non-fracture patients matched at 1∶1 ratio by propensity score matching based on age, gender, and body mass index. The fourth lumbar vertebra was selected as the region of interest (ROI) for the vertebral body, and the bilateral psoas major, erector spinae, and multifidus muscles were selected as the ROIs for the paraspinal muscles. A total of 7 259 radiomics features were extracted from these ROIs. The dataset was divided into a training set and a test set in an 8∶2 ratio by simple random sampling (osteoporosis group 241 and 61 cases, osteopenia group 211 and 53 cases). The T-score was used to establish the clinical model. After feature normalization and dimensionality reduction, logistic regression was applied to build three radiomics models: vertebral model, paraspinal muscle model, and vertebral-paraspinal muscle model. The T-score was then combined with the radiomics model that achieved the highest area under the receiver operating characteristic curve (AUC) in the test set to construct a clinical-radiomics combined model. Model performance was evaluated using the AUC. The DeLong test was used to compare the diagnostic efficacy between models. Results:In the test set, the vertebral-paravertebral muscle model achieved the highest AUC among radiomics models and was selected for combination with the T-score. In identifying potential vertebral fragility fractures of osteoporosis group, the AUC (95% CI) of the clinical model, vertebral model, paraspinal muscle model, vertebral-paraspinal muscle model, and clinical-radiomics model were 0.523 (0.373-0.672), 0.869 (0.779-0.959), 0.608 (0.464-0.752), 0.876 (0.791-0.961), and 0.860 (0.769-0.952), respectively. For osteopenia group, the corresponding AUC(95% CI) were 0.625 (0.467-0.783), 0.696 (0.547-0.845), 0.706 (0.563-0.848), 0.816 (0.702-0.930), and 0.820 (0.710-0.930). The DeLong test showed that the vertebral model for identifying the potential vertebral fracture risk in osteoporosis group had better performance than the paraspinal muscle model ( Z=3.28, P=0.001). While for osteopenia group, there was no significant difference in diagnostic performance between the vertebral model and the paraspinal muscle model ( Z=0.09, P=0.932). The recognition efficacy of the clinical model and the vertebral-paraspinal muscle model was significantly different ( Z=3.69, 1.98; P<0.001, P=0.047), while there was no significant difference between the clinical-radiomics combined model and the vertebral-paraspinal muscle model ( Z=1.51, 0.12; P=0.131, 0.904). Conclusion:The MRI-based vertebral-paraspinal muscle radiomics model can effectively identify osteoporosis or osteopenia patients with potential fragility fracture risk. In osteopenia group, the efficacy of the MRI radiomics models based on the vertebra and paraspinal muscles in identifying potential vertebral fragility fracture risk is comparable.

Objective:To explore the relationship between gallbladder polyps and colorectal polyps, providing insights into whether the presence of gallbladder polyps can serve as an indicator for colonoscopy screening.Methods:Clinical data from 2 542 patients who underwent colonoscopy and abdominal ultrasound at the First Affiliated Hospital of Shihezi University between January and December 2022 were retrospectively analyzed. Patients were divided into colorectal polyp group ( n=1 266) and non-colorectal polyp group ( n=1 276) based on colonoscopy findings. Univariate and multivariate Logistic regression models were used to analyze the relationship between gallbladder polyps and colorectal polyps. Results:The prevalence rates of gallbladder polyp in colorectal polyp group and non-colorectal polyp group were 16.67% (211/1 266) and 11.21% (143/1 276). Multivariate Logistic regression analysis showed a lower risk of colorectal polyps in women ( P<0.001, OR=0.523, 95% CI: 0.440-0.622). Age ( P<0.001, OR=1.059, 95% CI: 1.050-1.068), and hypertriglyceridemia ( P=0.013, OR=1.350, 95% CI: 1.066-1.709), low level of high-density lipoprotein ( P<0.001, OR=1.588, 95% CI: 1.280-1.969), and gallbladder polyp ( P<0.001, OR=1.712, 95% CI: 1.344-2.180) were independent risk factors for colorectal polyp. There was no significant difference in hypercholesterolemia, elevated low-density lipoprotein, hyperuricemia, or cholecystectomy between colorectal polyp group and non-colorectal polyp group ( P>0.05). Conclusion:The identification of gallbladder polyps via abdominal ultrasound may indicate a higher likelihood of colorectal polyps in patients, underscoring the need for further colonoscopy screening in individuals with gallbladder polyps.

The generalized anxiety disorder scale-7 (GAD-7) was used to screen anxiety symptoms, and the patient health questionaire-8 (PHQ-8) was performed to screen depression symptoms, and the general situation questionnaire was used to collect clinical information of patients. The questionnairs were completed via the Questionnaire Star platform or paper questionnaire, and a database was established. The patients were divided into groups according to whether with anxiety and depression symptoms. Multivariable logistic regression models was performed to analyze the factors related to anxiety and depression.Results:A total of 516 questionnaires were distributed and collected, among which 9 questionnaires were incomplete and 507 questionnaires were valid, the effective rate of questionnaires was 98.26%. The detection rates of anxiety and depression symptoms in 507 patients with colorectal polyps were 21.50%(109/507) and 19.33%(98/507), respectively. The results of multivariable logistic analysis revealed that female ( OR=3.87, 95% confidence interval (95% CI) 2.30 to 6.51, P<0.001), maximum diameter of polyp ( OR=1.74, 95% CI 1.14 to 2.67, P=0.011), perception of polyps as cancer ( OR=13.96, 95% CI 1.48 to 132.07, P=0.022), and the occurrence of gastrointestinal symptoms after polyp detection ( OR=5.43, 95% CI 1.74 to 16.92, P=0.004) were independent risk factors of anxiety in patients with colorectal polyps. Female ( OR=2.42, 95% CI 1.47 to 4.00, P=0.001), the number of polyps ( OR=1.07, 95% CI 1.01 to 1.13, P=0.028) and the count of gastrointestinal symptoms ( OR=2.04, 95% CI 1.34 to 3.10, P=0.001) were independent risk factors of depression in patients with colorectal polyps. Conclusion:Gender, polyp size, number of polyps, disease perception, and concomitant gastrointestinal symptoms are associated with anxiety and depression in patients with colorectal polyps.

To investigate the clinical role of T-cell transcription factor (TBX21) and adenylate cyclase 9 antibody (ADCY9) gene polymorphisms in the development of childhood asthma. METHODS: Two hundred Han Chinese wheezing children aged 5 years and younger in Henan region from July 2016 to January 2017 were selected as the study group, and another 100 Han Chinese healthy children aged 5 years and younger in the same period were selected as the control group. Oral mucosal exfoliated cells were collected from both groups, and the genotypes of TBX21 gene rs2240017 polymorphic locus and ADCY9 gene rs2230739 polymorphic locus were detected by real-time fluorescence quantitative polymerase chain reaction (PCR) technique, and the risk level of asthma was assessed based on the test results. The children in the low-risk and high-risk groups were compared in terms of serum immunoglobulin E (IgE) levels, API positivity rate and allergic disease incidence, and the correlation between the risk level of asthma-related genetic polymorphisms and serum IgE levels, API and allergic disease incidence was analyzed. All children were followed up until 6 years of age to confirm the diagnosis of asthma, and the incidence of asthma was compared between the low-risk and high-risk groups. Children with asthma were treated with inhaled glucocorticoids and leukotriene receptor antagonists for 3 months, and the control of asthma and the impairment of lung function were compared between the low-risk and high-risk groups. RESULTS: The genotype detection results of rs2240017 polymorphic locus of TBX21 gene and rs2230739 polymorphic locus of ADCY9 gene in the study group compared with those in the control group were statistically significant (P<0.001). The percentages of CC, CT, and TT genotypes of rs2240017 polymorphic locus of TBX21 gene were 19.50%, 56.00%, and 24.50%, respectively, and the percentages of CC, CG, and GG genotypes of rs2230739 polymorphic locus of ADCY9 gene were 86.00%, 10.00%, and 4.00%, respectively, in 200 children with wheezing; serum IgE level, API positivity rate and allergic disease incidence were higher in the high-risk group than in the low-risk group (P< 0.001, <0.001, 0.021, respectively). The degree of risk of asthma-related gene polymorphisms in children with wheezing was positively correlated with serum IgE levels, API positivity, and the incidence of allergic diseases (P<0.001); the incidence of asthma (81.48%) and impaired lung function (74.07%) were higher in the high-risk group than in the low-risk group (4.90%, 3.50%) (P<0.001). There was no statistically significant difference between the asthma control rate of children with asthma in the high-risk group (79.55%) compared with the asthma control rate of children with asthma in the low-risk group (100.00%) (P=0.433). CONCLUSION: Gene polymorphisms at rs2240017 locus of TBX21 gene and rs2230739 locus of ADCY9 gene are closely associated with asthma development and impaired lung function in children with wheezing.

Objective To explore ancient and modern medication laws of aromatic Chinese medicines in treating angina pectoris, and to provide new ideas for the clinical treatment. Methods With “angina pectoris” as the key word, ancient books prescriptions and Chinese patent medicines related to angina pectoris were collected from China National Knowledge Infrastructure (CNKI), Traditional Chinese Medicine Database System, Chinese Medicine Prescription Database, New National Proprietary Chinese Medicine (2nd edition), and Chinese Pharmacopoeia (2020 edition) from January 1, 2015 to December 31, 2021. Core high-frequency aromatic Chinese medicines were defined, and their potential medication rules were analyzed and summarized. Microsoft Access 2010 was used for data management. Data analysis software, including Excel and IBM SPSS Modeler 18.0 were used for drug association rule analysis, and Cytoscape 3.7.2 for visual display. Results There were 67 ancient books prescriptions and 258 Chinese patent medicines containing aromatic Chinese medicines treating angina pectoris collected from relevant databases. In ancient books prescriptions, there were nine aromatic Chinese medicines with the frequency ≥10, and the most commonly used medicine was Danggui (Angelicae Sinensis Radix), followed by Chenpi (Citri Reticulatae Pericarpium). There were 33 aromatic Chinese medicines with the frequency ≥10 in Chinese patent medicines, and the most commonly used medicine was Danshen (Salviae Miltiorrhizae Radix et Rhizoma), followed by Chuanxiong (Chuanxiong Rhizoma) and Sanqi (Notoginseng Radix et Rhizoma). In ancient books prescriptions, the medicines mainly belonged to intenal-warming medicines, Qi-regulating medicines, and blood circulation promoting and blood stasis removing medicines. There were eight medicine pairs with confidence equal to 100% in ancient books prescriptions, the most frequently used pairs were Chuanxiong (Chuanxiong Rhizoma) + Danggui (Angelicae Sinensis Radix), and Xiangfu (Cyperi Rhizoma) + Chenpi (Citri Reticulatae Pericarpium). In Chinese patent medicines, the aromatic Chinese medicine Chuanxiong (Chuanxiong Rhizoma) could be combined with many other Chinese medicines, among which the Confidence and Support of Chuanxiong (Chuanxiong Rhizoma) + Danshen (Salviae Miltiorrhizae Radix et Rhizoma) were at a high level. Conclusion Aromatic Chinese medicines for the treatment of angina pectoris of coronary heart disease are mainly warm, and the flavors are mainly pungent, sweet, and bitter. They mainly access to the liver, gallbladder, and pericardium meridians. The treatment of angina pectoris of coronary heart disease mainly focuses on warming heart pulse, and promoting blood circulation and removing blood stasis.

To investigate the relationship between single nucleotide polymorphisms (SNPs) of CACNA1C (SNPs rs58619945, rs7316246 and rs216008) and susceptibility of chronic spontaneous urticaria (CSU) as well as the curative effect of non-sedating antihistamine drugs.
 Methods: Peripheral blood were extracted from 191 CSU patients to collect DNA. Urticaria Activity Score 7 (UAS7) and Dermatology Life Quality Index (DLQI) changes were collected from these patients with different non-sedating antihistamine drugs. PubMed retrieval system was used to select the 3 SNPs (rs58619945, rs7316246 and rs216008) of CACNA1C. Susceptibility of CSU and curative effect of non-sedating antihistamine drugs (desloratadine, mizolastine, fisofenadine) in 189 CSU patients and 105 controls with different SNPs were compared with Chi-squared test. Data of 105 southern Chinese controls were extracted from the 1 000 genome database.
 Results: Frequency of rs58619945 G allele in the CSU patients was significantly higher than that in the controls [OR(95%CI)=0.660(0.470-0.925), P=0.016]. However, there was no significant differences in rs7316246 and rs216008 between the CSU patients and the controls. Meanwhile there was no significant difference in general curative effect of the 3 drugs in the 3 SNPs (rs58619945: OR=0.843, P=0.454; rs7316246: OR=2.103, P=0.102; rs216008: OR=0.237, P=0.363). There was significant difference in different alleles of rs216008 in the patients administered by desloratadine [OR(95%CI)=0.480(0.247-0.933), P=0.029]. No difference was shown in the 3 SNPs in patients administered by mizolastine.
 Conclusion: The rs58619945 A/G might be related to susceptibility of CSU, and the rs216008 mutation might affect drug response of desloratadine.
