Objective To explore the recognition capabilities of electronic nose combined with machine learning in identifying the breath odor map of benign and malignant pulmonary nodules and Traditional Chinese Medicine (TCM) syndrome elements. Methods The study design was a single-center observational study. General data and four diagnostic information were collected from 108 patients with pulmonary nodules admitted to the Department of Cardiothoracic Surgery of Hospital of Chengdu University of TCM from April 2023 to March 2024. The patients' TCM disease location and nature distribution characteristics were analyzed using the syndrome differentiation method. The Cyranose 320 electronic nose was used to collect the odor profiles of oral exhalation, and five machine learning algorithms including random forest (RF), K-nearest neighbor (KNN), logistic regression (LR), support vector machine (SVM), and eXtreme gradient boosting (XGBoost) were employed to identify the exhaled breath profiles of benign and malignant pulmonary nodules and different TCM syndromes. Results (1) The common disease locations in pulmonary nodules were ranked in descending order as liver, lung, and kidney; the common disease natures were ranked in descending order as Yin deficiency, phlegm, dampness, Qi stagnation, and blood deficiency. (2) The electronic nose combined with the RF algorithm had the best efficacy in identifying the exhaled breath profiles of benign and malignant pulmonary nodules, with an AUC of 0.91, accuracy of 86.36%, specificity of 75.00%, and sensitivity of 92.85%. (3) The electronic nose combined with RF, LR, or XGBoost algorithms could effectively identify the different TCM disease locations and natures of pulmonary nodules, with classification accuracy, specificity, and sensitivity generally exceeding 80.00%.Conclusion Electronic nose combined with machine learning not only has the potential capabilities to differentiate the benign and malignant pulmonary nodules, but also provides new technologies and methods for the objective diagnosis of TCM syndromes in pulmonary nodules.

Objective To analyze the differences in distribution of traditional Chinese medicine (TCM) syndrome elements and salivary microbiota between the individuals with pulmonary nodules and those without, and to explore the potential correlation between the distribution of TCM syndrome elements and salivary microbiota in patients with pulmonary nodules. Methods We retrospectively recruited 173 patients with pulmonary nodules (PN) and 40 healthy controls (HC). The four diagnostic information was collected from all participants, and syndrome differentiation method was used to analyze the distribution of TCM syndrome elements in both groups. Saliva samples were obtained from the subjects for 16S rRNA high-throughput sequencing to obtain differential microbiota and to explore the correlation between TCM syndrome elements and salivary microbiota in the evolution of the pulmonary nodule disease. Results The study found that in the PN group, the primary TCM syndrome elements related to disease location were the lung and liver, and the primary TCM syndrome elements related to disease nature were yin deficiency and phlegm. In the HC group, the primary TCM syndrome elements related to disease location were the lung and spleen, and the primary TCM syndrome elements related to disease nature were dampness and qi deficiency. There were differences between the two groups in the distribution of TCM syndrome elements related to disease location (lung, liver, kidney, exterior, heart) and disease nature (yin deficiency, phlegm, qi stagnation, qi deficiency, dampness, blood deficiency, heat, blood stasis) (P<0.05). The species abundance of the salivary microbiota was higher in the PN group than that in the HC group (P<0.05), and there was significant difference in community composition between the two groups (P<0.05). Correlation analysis using multiple methods, including Mantel test network heatmap analysis and Spearman correlation analysis and so on, the results showed that in the PN group, Prevotella and Porphyromonas were positively correlated with disease location in the lung, and Porphyromonas and Granulicatella were positively correlated with disease nature in yin deficiency (P<0.05). Conclusion The study concludes that there are notable differences in the distribution of TCM syndrome elements and the species abundance and composition of salivary microbiota between the patients with pulmonary nodules and the healthy individuals. The distinct external syndrome manifestations in patients with pulmonary nodules, compared to healthy individuals, may be a cascade event triggered by changes in the salivary microbiota. The dual correlation of Porphyromonas with both disease location and nature suggests that changes in its abundance may serve as an objective indicator for the improvement of symptoms in patients with yin deficiency-type pulmonary nodules.

OBJECTIVE To systematically evaluate the real-world effectiveness and safety of belimumab in the treatment of lupus nephritis (LN) in Chinese adult patients. METHODS Retrieved from PubMed, Embase, Web of Science, Cochrane Library, Wanfang data, CNKI, VIP and CBM, real-world studies on belimumab in the treatment of LN in Chinese adult patients were collected from the inception to July 7th, 2023. Two reviewers independently screened the literature, extracted data, and assessed the quality of the included studies. Meta-analysis was then performed using RevMan 5.3 software. RESULTS A total of 10 real- world studies were included, involving 253 Chinese adult patients with LN. The results of the meta-analysis demonstrated that the complete renal response rate, partial renal response rate, and the incidence of adverse reaction rate in Chinese adult patients with LN treated with belimumab were 61% (95%CI was 46%-76%, P<0.000 01), 23%(95%CI was 2%-44%, P=0.03), and 30% (95%CI was 16%-43%, P<0.000 01), respectively. Belimumab could reduce the 24-hour urinary protein (MD=-1.71, 95%CI was -3.02--0.40, P=0.01), urine protein-creatinine ratio (MD=-1.76,95%CI was -2.06--1.46,P<0.000 01), the systemic lupus erythematosus disease activity index (MD=-8.63, 95%CI was -12.12--5.13, P<0.000 01), and glucocorticoids dosage (MD=-18.65, 95%CI was -31.82--5.48, P=0.006). In addition, it could elevate the levels of complement C3 (MD=0.19, 95%CI was 0.08-0.30, P=0.000 6) and complement C4 (MD=0.06, 95%CI was 0.02-0.09, P=0.001). However, belimumab could not improve the levels of serum creatinine and estimated glomerular filtration rate (P>0.05). CONCLUSIONS Belimumab has good efficacy and safety in Chinese adult patients with LN.

Objective:To study the distribution and antibiotics resistance of the main pathogens of neonatal purulent meningitis in different regions of China.Methods:A retrospective descriptive clinical epidemiological study was conducted in children with neonatal purulent meningitis which admitted to 18 tertiary hospitals in different regions of China between January 2015 to December 2019. The test results of blood and cerebrospinal fluid, and drug sensitivity test results of the main pathogens were collected. The distributions of pathogenic bacteria in children with neonatal purulent meningitis in preterm and term infants, early and late onset infants, in Zhejiang Province and other regions outside Zhejiang Province, and in Wenzhou region and other regions of Zhejiang Province were analyzed. The chi-square test was used for statistical analysis.Results:A total of 210 neonatal purulent meningitis cases were collected. The common pathogens were Escherichia coli ( E. coli)(41.4%(87/210)) and Streptococcus agalactiae ( S. agalactiae)(27.1%(57/210)). The proportion of Gram-negative bacteria in preterm infants (77.6%(45/58)) with neonatal purulent meningitis was higher than that in term infants (47.4%(72/152)), and the difference was statistically significant ( χ2=15.54, P=0.001). There were no significant differences in the constituent ratios of E. coli (36.5%(31/85) vs 44.8%(56/125)) and S. agalactiae (24.7%(21/85) vs 28.8%(36/125)) between early onset and late onset cases (both P>0.05). The most common pathogen was E. coli in different regions, with 46.7%(64/137) in Zhejiang Province and 31.5%(23/73) in other regions outside Zhejiang Province. In Zhejiang Province, S. agalactiae was detected in 49 out of 137 cases (35.8%), which was significantly higher than other regions outside Zhejiang Province (11.0%(8/73)). The proportions of Klebsiella pneumoniae, and coagulase-negative Staphylococcus in other regions outside Zhejiang Province (17.8%(13/73) and 16.4%(12/73)) were both higher than those in Zhejiang Province (2.9%(4/137) and 5.1%(7/137)). The differences were all statistically significant ( χ2=14.82, 12.26 and 7.43, respectively, all P<0.05). The proportion of Gram-positive bacteria in Wenzhou City (60.8%(31/51)) was higher than that in other regions in Zhejiang Province (38.4%(33/86)), and the difference was statistically significant ( χ2=6.46, P=0.011). E. coli was sensitive to meropenem (0/45), and 74.4%(32/43) of them were resistant to ampicillin. E. coli had different degrees of resistance to other common cephalosporins, among which, cefotaxime had the highest resistance rate of 41.8%(23/55), followed by ceftriaxone (32.4%(23/71)). S. agalactiae was sensitive to penicillin, vancomycin and linezolid. Conclusions:The composition ratios of pathogenic bacteria of neonatal purulent meningitis are different in different regions of China. The most common pathogen is E. coli, which is sensitive to meropenem, while it has different degrees of resistance to other common cephalosporins, especially to cefotaxime.

Objective:To investigate the effects of Ureaplasma urealyticum GrpE ( Uu-GrpE) on the maturation of dendritic cells and the polarization of T cells. Methods:Uu-GrpE was expressed and purified, and then identified by Western blot. The cytotoxicity of Uu-GrpE to mouse bone marrow-derived dendritic cells (BMDCs) was analyzed by LDH kit. After stimulating BMDCs with Uu-GrpE, the expression of costimulatory molecules, CD80, CD86 and major histocompatibility complex Ⅱ (MHCⅡ), on the surface of BMDCs was detected by flow cytometry, and ELISA was used to detect the cytokines such as IL-12p70, TNF-α, IL-1β and IL-6. CD4 + Na?ve T cells were isolated from mouse spleen tissues by magnetic beads. A co-culture system of BMDCs and Na?ve T cells was constructed to analyze the effects of GrpE-stimulated mature BMDCs (GrpE-BMDCs) on T cell proliferation and polarization towards Th1/Th2. Mice were immunized with GrpE-BMDCs through the tail vein, and the induced humoral and cellular immune responses were detected by ELISA and flow cytometry. Results:Uu-GrpE was successfully express and high purity BMDCs were isolated. Uu-GrpE could stimulate BMDCs to secrete cytokines such as IL-12p70, TNF-α, IL-1β and IL-6 without having cytotoxicity. Uu-GrpE significantly increased the expression of CD80 [mean flourscence indensity (MFI): (324.00±22.11) vs (91.03±10.95), P<0.01], CD86 [MFI: (1 176.00±51.39) vs (217.00±14.93), P<0.01] and MHCⅡ [MFI: (708.70±56.32) vs (185.70±16.77), P<0.01] on BMDCs. Compared to the GrpE-BMDCs only group and GrpE (boiled)-BMDCs+ T cell group, the GrpE-BMDCs+ T cell group showed significantly increased T cell proliferation [stimulation index: (7.25±0.21) vs(6.55±0.23) and (6.09±0.35), both P<0.05], and dramatically promoted T cell secretion of IL-2 and IFN-γ [IL-2: (145.60±14.67) pg/ml vs(55.92±3.12) pg/ml and (26.05±2.40) pg/ml, P<0.05 and P<0.01; IFN-γ: (267.20±37.80) pg/ml vs(146.70±20.65) pg/ml and(27.84±6.69) pg/ml, both P<0.05]. However, no significant change was observed in the expression of Th2-type cytokines. Moreover, the adoptive transfer of GrpE-BMDCs induced a Th1-type immune response. Conclusions:Uu-GrpE could stimulate the maturation and polarization of BMDCs. Moreover, it could induce Th1 immune response as a candidate protein vaccine for Ureaplasma urealyticum.
