Irritable bowel syndrome (IBS) is a functional bowel disorder characterized primarily by abdominal pain and altered defecation habits. In recent years, traditional Chinese medicine (TCM) has made progress in multiple aspects of IBS research and treatment, including syndrome distribution, development of TCM formulas, clinical efficacy evaluation, external therapies, and psychosocial regulation. However, it still faces challenges such as over-reliance on symptomatic manifestations rather than biomarkers for diagnostic criteria, and the lack of high-quality evidence-based data supporting the efficacy of TCM formulas in treating IBS. This paper proposed that TCM diagnosis and treatment of IBS should adhere to the strategy of integrating the holistic concept with syndrome differentiation and treatment, combining TCM external therapies such as acupuncture, moxibustion and acupoint application), and emphasizing individualized diagnosis and treatment for psychosomatic abnormalities. Future research should integrate multi-omics technologies, artificial intelligence and other methods to deepen the understanding of the pathogenesis of IBS and the mechanisms of TCM formulas, so as to promote the standardization and internationalization of TCM in the diagnosis and treatment of IBS.

ObjectiveTo investigate the ability of clinically isolated, Helicobacter pylori (H. pylori)-specific gene polymerase chain reaction (PCR)-positive gastric, vaginal, and fecal Candida to release H. pylori. MethodsResuscitate 4 strains of H. pylori -specific 16S rDNA and ureA gene PCR-positive Candida strains isolated in laboratory from clinical sources, including 1 strain of gastric Candida, 1 strain of fecal Candida, 2 strains of vaginal Candida and the standard Candida albicans strain ATCC10231 (Ca10231). The presence of H. pylori-specific ureA in the 5 strains of Candida isolates was confirmed by PCR. The aforementioned strains of Candida and H.pylori were inoculated into urea medium and cultured in a constant temperature incubator at 37 ℃. The color change of the medium was observed daily. A change in the medium's color from yellow to red indicated the presence of urease activity. Then, the five strains of Candida and H. pylori were co-incubated with the magnetic beads coated with H. pylori antibodies respectively. Scanning electron microscopy (SEM) was employed to observe the presence of bacilli adsorbed on the surface of the magnetic beads. PCR was used to detect the presence of H.pylori-specific 16S rDNA and ureA genes on magnetic beads. ResultsThe PCR analysis of the ureA gene in the four Candida isolates was positive, whereas the Ca10231 strain tested negative. Upon culturing the four Candida isolates on urea medium, the medium color changed from yellow to red which was determined to be urease positive, while the medium containing Ca10231 remained unchanged, which was urease negative. SEM revealed that bacilli could be observed on the surface of magnetic beads co-incubated with the 4 strains of Candida of clinical origin and H.pylori isolate. Specifically, PCR testing of the magnetic beads co-incubated with one vaginal Candida, one gastric Candida and H.pylori isolate showed positive results for the 16S rDNA and ureA genes of H. pylori; however, the PCR tests for the two genes were negative for the magnetic beads co-incubated with the other two Candida isolate. ConclusionThis study demonstrates that H. pylori-specific genes Candida can release H. pylori.

Based on plasma lipidomics combined with machine learning approaches, this study aimed to screen molecular biomarkers for the diagnosis of early-stage lung cancer in elderly patients and to evaluate their diagnostic performance. This was a retrospective diagnostic study consisting of two parts. The first part involved molecular biomarker screening. Elderly patients with early-stage lung cancer (early lung cancer group), patients with benign pulmonary nodules (benign nodule group), and contemporaneous healthy individuals undergoing physical examinations (healthy control group) were enrolled from Peking University People's Hospital between November 2023 and November 2024. In addition, early-stage lung cancer patients and healthy controls meeting the inclusion criteria from a previous study of our research group were included as an independent validation cohort. Plasma samples were collected from all subjects, and untargeted lipidomics analysis was performed using high-performance liquid chromatography-mass spectrometry. Principal component analysis and orthogonal partial least squares discriminant analysis were used to evaluate metabolic differences between groups. L1-regularized support vector machine combined with incremental feature selection was employed to screen diagnostic biomarkers for early-stage lung cancer. Model performance was assessed using receiver operating characteristic curves, calibration curves, Brier scores, and decision curve analysis. The second part involved functional validation of the molecular biomarkers using the human lung adenocarcinoma cell line A549, with palmitoylcarnitine (CAR 16∶0) selected as a representative biomarker for functional validation via CCK-8 and cell scratch assays. A total of 36 patients in the early lung cancer group, 35 patients in the benign nodule group, and 41 healthy controls were enrolled, along with an independent validation cohort of 110 individuals (59 patients with early-stage lung cancer and 51 healthy controls). The principal component analysis results demonstrated that quality control samples were tightly aggregated at the centroid of all samples, reflecting robust instrument performance and dependable data quality.Orthogonal partial least squares discriminant analysis revealed significant metabolic differences between the early lung cancer group and the control group (benign nodule group + healthy control group) (R2X=0.406, R2Y=0.529, Q2Y=0.44). L1-regularized support vector machine identified five carnitine-related lipids-palmitoleoylcarnitine(CAR 16∶1), palmitoylcarnitine, The five plasma carnitine-related lipids screened based on untargeted lipidomics and machine learning may serve as potential molecular biomarkers for the diagnosis of early-stage lung cancer in elderly patients. The high-sensitivity characteristic of the model makes it particularly suitable for screening scenarios in early-stage lung cancer.

Objective:To analyze the correlation of bone mineral density (BMD) , serum transforming growth factor β1 (TGF- β1) , and retinol-binding protein 4 (RBP4) with osteoporosis in gestational diabetes mellitus (GDM) . Methods:A total of 180 GDM patients admitted to Department of Gynecology, Second Hospital of Tianjin Medical University from Jan. 2022 to Jan. 2024 were included as the observation group, and 30 healthy pregnant women undergoing examination at the same time were included into the control group. BMD [stiffness index (SI) , broadband ultrasound attenuation (BUA) , speed of sound (SOS) ], serum TGF-β1, and RBP4 levels were compared between the two groups; GDM women with complicated with osteoporosis were included in the osteoporosis subgroup, and pregnant women without osteoporosis were included in the non-osteoporosis subgroup. BMD, serum TGF- β1 and RBP4 levels were compared between the two groups, and the relationship among bone mineral density and serum TGF- β1, RBP4 was analyzed by Pearson correlation. Receiver operating characteristic curve (ROC) curve was drawn to evaluate the diagnostic value of serum TGF- β1 and RBP4 levels in GDM complicated with osteoporosis. Results:The observation group had significantly higher levels of serum TGF- β1 and RBP4 than the control group, while lower BUA, SOS and SI ( t=99.04, 28.48, 4.10, 3.54, 6.29, P < 0.05) ; Among 180 pregnant women with GDM, 38 cases had osteoporosis and 142 cases did not have osteoporosis. The osteoporosis subgroup had significantly higher serum TGF- β1 and RBP4 levels than the other subgroup, while BMD indexes such as BUA, SOS and SI were significantly lower ( t=3.35, 3.48, 3.77, 2.85, 3.41, P < 0.05) ; Pearson correlation analysis showed that BMD indexes, such as BUA, SOS and SI, were significantly correlated with serum TGF- β1 and RBP4 in pregnant women with GDM ( r=-0.61, 0.58, -0.60, -0.58, -0.60, -0.63, P<0.05) ; The area under the curve (AUC) of TGF- β1, RBP4 and combined detection of GDM women with osteoporosis was 0.572, 0.653 and 0.659, respectively. Conclusions:In GDM women complicated with osteoporosis, the levels of serum TGF- β1 and RBP4 increase significantly, and BMD decreases significantly. Serum TGF- β1 and RBP4 in GDM women are closely related to BMD index, which can provide early diagnosis basis for GDM complicated with osteoporosis.
