Objective:To investigate the risk factors and construct a nomogram prediction model for neonatal bacterial meningitis (BM).Methods:A retrospective cohort study was conducted on 1 228 neonates who underwent lumbar puncture for cerebrospinal fluid examination in the Department of Neonatology at Gansu Provincial Women and Child Healthcare Hospital from December 2019 to February 2024. The subjects were randomly divided into a training cohort and a validation cohort at a ratio of 7∶3 using a computer program. Rank sum test or Chi-square tests were used to compare differences between the two cohorts. The subjects were divided into BM and non-BM groups based on the presence or absence of BM. Multivariate logistic regression analysis (forward stepwise regression method) was used in the training cohort to identify risk factors for BM. The area under the receiver operating characteristic curve (AUC) and the Hosmer-Lemeshow goodness-of-fit test were used to assess the discrimination and calibration of the model, respectively. Calibration curves were used to evaluate the accuracy of the model and to construct the nomogram. Internal validation was performed using the Bootstrap resampling method. Decision curve analysis was used to assess the clinical utility of the model. Results:Among the 1 228 neonates, 151 (12.3%) had BM. The training cohort included 859 neonates, of whom 106 (12.3%) had BM and 753 (87.7%) did not. The validation cohort included 369 neonates, of whom 45 (12.2%) had BM and 324 (87.8%) did not. The results of the multivariate logistic regression analysis in the training cohort showed that sepsis ( OR=4.446, 95% CI:2.583-7.653), convulsions ( OR=3.749, 95% CI:1.930-7.280), high maximum body temperature ( OR=2.027, 95% CI:1.636-2.513), and elevated C-reactive protein ( OR=1.007, 95% CI:1.003-1.012) were independent risk factors for BM, while greater gestational age at birth ( OR=0.946, 95% CI: 0.898-0.995) and higher hemoglobin levels ( OR=0.990, 95% CI:0.981-0.998) were protective factors for BM (all P<0.05). Based on these findings, a nomogram prediction model for neonatal BM was constructed and validated for accuracy. The AUC values of the nomogram model in the training and validation cohorts were 0.796 (95% CI: 0.750-0.843) and 0.781 (95% CI: 0.700-0.862), respectively. The Hosmer-Lemeshow goodness-of-fit test showed P>0.05 in both cohorts. The clinical decision curve analysis demonstrated good net benefit across most threshold ranges. Conclusions:Sepsis, convulsions, high maximum body temperature, and elevated C-reactive protein increase the risk of neonatal BM. The nomogram model constructed based on these factors, combined with gestational age and hemoglobin levels, provides a reference value for predicting the risk of neonatal BM.

In recent years, traditional Chinese medicine (TCM) has made great progress in the prevention and treatment of cancer. It has gradually revealed its characteristics and advantages in clinical practice, including alleviating clinical symptoms, prolonging survival time, decreasing the adverse effects of chemotherapy, and improving living quality. However, clinical TCM treatment of cancer lacks systematic theoretical guidance, because ancient TCM has not formed a recognized theoretical system of cognitive cancer, and there still are different opinions on the pathogenesis of cancer. Due to the complexity of cancer, the essence of cancer pathogenesis has not been described accurately by using common pathogenic factors, such as pathogenic wind, cold, dampness, summer heat, dryness, and fire. Ancient and modern TCM physicians have a similar understanding that the occurrence of cancer is related to toxin. In the 1990s, the thought of cancerous toxin was first proposed by Prof Zhou Zhongying, a TCM master based on more than 60 years of clinical practice, who used “pandemic Qi (Li-Qi) is a specific pathogenic factor of epidemic disease” in Wenyi Lun (Treatise on Pestilence) for references. The pathogenesis theory of cancerous toxin was gradually established under the guidance of the thought of cancerous toxin. It holds that the cancerous toxin, a special pathogenic factor of cancer, is the key pathogenesis of the occurrence of malignant tumors. According to the pathogenesis theory of cancerous toxin, the basic pathogenesis of malignant tumors is the accumulation of pathogenic factors and cancerous toxin, and the deficiency of the vital Qi (Zheng-Qi). Therefore, the treatment principle involves eliminating pathogenic factors, resolving cancerous toxin, and supporting the vital Qi. The anticancer detoxification methods and the classification of Chinese medicinal herbs with anticancer detoxification effects were put forward. System theory has much in common with the concepts in the theory system of TCM, such as the universal relation theory, asking for a concrete analysis of concrete conditions, the humanism thought, and so on. This article aims to describe, review, and analyze the pathogenesis theory of cancerous toxin based on system theory for clinical practices.

Objective To investigate the effect of rh-resistin on lipid metabolism in HepG2 cells and to elucidate its relation to AMPK pathway. Methods We treated the HepG2 cells with 50 ng/ml rh-resistin and 0.5 mmol/L palmitic acid,used siRNA technique to inhibite α2 subunite expression of AMPK in HepG2 cells and quantitative RT-PCR to detect ACC1,ACC2,and HL mRNA expression levels of related lipid metabolism genes. The P-AMPK-Thr172 of AMPK and P-ACC-Ser79 of ACC were determined by Western blotting. The Lipid accumu-lation in cells was determined by images of Laser Scanning Confocal Microscope after Nile red staining. Results Rh-resistin decreased the AMPKα2,HL mRNA expressions and the phosphorylation level of AMPK and ACC in both basal and insulin-stimulated conditions (P < 0.05),had no influence on ACC2 mRNA expressions (P >0.05),while it increased ACC2 mRNA expressions and cytoplasmic lipid droplets in the same conditions (P <0.05). Conclusion Rh-resistin may affect lipid metabolism via AMPK pathway with increase of fatty acid synthe-sis and inhibition of triglyceride catabolism,which leading to lipid accumulation in HepG2 cells.
