As the important source of bone cells, osteoblasts are involved in bone formation and repair, and play a key role in maintaining bone balance. If the osteogenic differentiation process in vivo is disrupted, a variety of bone-related diseases may occur. Natural products, which have a wide range of sources, a wide variety of physiological activities, and few toxic side-effects, have been found in recent years to be able to regulate osteoblast differentiation. Based on the sources of natural products, this paper reviews the intervention of natural products from plant, animal and microbial sources on osteogenic differentiation, aiming to provide a theoretical basis for natural products in the treatment of bone diseases.

Objective To identify the multidimensional needs of postoperative gastric cancer patients for home-based nutritional management based on patient journey maps,and to provide a reference for carrying out nutritional management interventions.Methods Using descriptive qualitative research methods,we facilitated semi-structured in-depth interviews with 9 pairs of postoperative gastric cancer homebound patients and their primary caregivers from a tertiary general hospital in Yichang City,China,from September 2024 to January 2025,and analysed the data and drew the patient journey maps by content analysis.Results Totally 24 sub-themes were summarised from 4 aspects,namely tasks,emotions,pain points and opportunity points,and journey maps involving the acute recovery period,the transitional adaptation period and the nutritional reconstruction period were formed.Conclusion The nutritional needs of homebound patients after gastric cancer surgery are complex and variable,and their needs for dietary guidance,eating-related symptom management,and real-time counselling are highlighted.In the future,appropriate intervention strategies can be developed based on the journey maps to meet the multidimensional nutritional needs of patients.

Andrographolide sulfonate (AS) is a sulfonated derivative of andrographolide extracted from Andrographis paniculata (Burm.f.) Nees, and has been approved for several decades in China. The present study aimed to investigate the novel therapeutic application and possible mechanisms of AS in the treatment of rheumatoid arthritis. Results indicated that administration of AS by injection or gavage significantly reduced the paw swelling, improved body weights, and attenuated pathological changes in joints of rats with adjuvant-induced arthritis. Additionally, the levels of tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), and IL-1β in the serum and ankle joints were reduced. Bioinformatics analysis, along with the spleen index and measurements of IL-17 and IL-10 levels, suggested a potential relationship between AS and Th17 cells under arthritic conditions. In vitro, AS was shown to block Th17 cell differentiation, as evidenced by the reduced percentages of CD4⁺ IL-17A⁺ T cells and decreased expression levels of RORγt, IL-17A, IL-17F, IL-21, and IL-22, without affecting the cell viability and apoptosis. This effect was attributed to the limited glycolysis, as indicated by metabolomics analysis, reduced glucose uptake, and pH measurements. Further investigation revealed that AS might bind to hexokinase2 (HK2) to down-regulate the protein levels of HK2 but not glyceraldehyde-3-phosphate dehydrogenase (GAPDH) or pyruvate kinase M2 (PKM2), and overexpression of HK2 reversed the inhibition of AS on Th17 cell differentiation. Furthermore, AS impaired the activation of phosphatidylinositol 3-kinase (PI3K)/protein kinase B (AKT) signals in vivo and in vitro, which was abolished by the addition of lactate. In conclusion, AS significantly improved adjuvant-induced arthritis (AIA) in rats by inhibiting glycolysis-mediated activation of PI3K/AKT to restrain Th17 cell differentiation.

Objective:To learn about the epidemic characteristics of human brucellosis in Baoji City, and to identify brucellosis strains, so as to provide scientific basis for precise prevention and control of brucellosis in the city.Methods:A retrospective analysis method was used to conduct a descriptive epidemiological analysis of brucellosis cases in Baoji City reported in the China Disease Prevention and Control Information System from 2009 to 2022. Bacteriology culture, serum agglutination, biochemical test, phage cleavage and PCR were used to identify the isolates and nucleic acids, respectively.Results:From 2009 to 2022, a total of 314 cases of human brucellosis were reported in Baoji City, with an average annual incidence rate of 0.62/100 000, The incidence rate of different years was compared, the difference was statistically significant (χ 2 = 51 748 520.36, P < 0.001). The gender ratio of male to female was 3.30 ∶ 1.00 (241 ∶ 73). The age distribution ranged from 2 to 84 years old, with a median of 50 years old. The cases were concentrated in the 30 - 59 age group (206 cases, 65.61%), followed by the 60 - 84 age group (80 cases, 25.48%) and the 2 - 29 age group (28 cases, 8.92%). The peak of incidence was from April to August, with a total of 205 cases, accounting for 65.29%. Cases were reported in 213 townships, with the number of townships increasing from 1 in 2009 to 29 in 2022. The median time interval between onset and diagnosis of the case was 11 days. There was no significant difference in the time interval between onset and diagnosis among different genders, occupation and regions ( P > 0.05). A total of 10 strains of Brucella were isolated and identified as Brucella genus by BCSP31-PCR, and as Brucella melitensis by AMOS-PCR. After comprehensive identification, 4 strains were Brucella melitensis 3, 3 strains were mutant Brucella melitensis, and 3 strains were Brucella melitensis 1. Conclusion:The epidemic of brucellosis in Baoji City shows a fluctuating upward trend, with the epidemic scope gradually expanding, and the infected strains are all Brucella melitensis.

To analyze the correlation of ADH4 exon rs1126671 and ADH7 exon rs971074 polymorphisms with risky drinking behaviors and alcoholic liver disease. The patients with alcoholic liver disease diagnosed in the Gastroenterology Department of the People′s Hospital of Hechi from November 2021 to June 2022, including 52 cases of alcoholic liver disease with positive risky drinking behaviors, 103 cases of non-alcoholic liver disease with positive risky drinking behaviors of the same gender and age, and 105 healthy subjects with no risky drinking behaviors as control groups were retrospectively analyzed. The serum total protein and albumin are detected by immunoturbidimetry and globulin is calculated by the difference method; the serum total bilirubin and direct bilirubin are detected by the nitrite oxidation method and indirect bilirubin is calculated by the difference method; alkaline phosphatase, aspartate aminotransferase, alanine aminotransferase and γ-glutamyl transferase are detected by the substrate method. The results revealed that all 52 patients with alcoholic liver disease were male. The non-parametric independent sample Kruskal-Wallis test was adopted to analyze the baseline of twelve liver functions among the alcoholic liver disease group, the risky drinking behavior group and the healthy control group, and it was found there was statistical significance in ten major liver function indicators in the difference comparison among the three groups like serum total protein (g/L) 65.0 (60.1, 71.4), 73.4 (70.3, 76.3), 72.4 (69.2, 76.2) ( H=37.130, P<0.001); albumin (g/L) 36.1 (28.6, 42.9), 47.2 (45.0, 49.2), 47.5 (45.9, 49.5) ( H=14.503, P=0.001); direct bilirubin (μmol/L) 10.1 (35.6, 34.0.1), 3.8 (3.1, 5.45), 4.2 (2.9, 6.0) ( H=26.608, P<0.001); alkaline phosphatase (U/L) 106.0 (71.0, 164.0), 68.0 (57.5, 82.0), 70.0 (59.0, 87.0) ( H=27.904, P<0.001); albumin to globulin 1.34 (0.91, 1.88), 1.82 (1.65, 2.00), 1.89 (1.68, 2.07) ( H=11.047, P=0.004); direct bilirubin to indirect bilirubin 0.91 (0.69, 1.91), 0.41 (0.35, 0.54), 0.42 (0.34, 0.54) ( H=19.478, P<0.001); serum total bilirubin (μmol/L) 23.9 (13.7, 51.0), 13.8 (10.2, 17.9), 13.0 (10.1, 17.4) ( H=18.375, P<0.001); aspartate aminotransferase (U/L) 74.0 (39.0, 122.0), 22.0 (19.0, 28.0), 23.0 (19.0, 30.0) ( H=76.365, P<0.001); alanine aminotransferase (U/L) 37.0 (25.0, 55.0), 23.0 (17.0, 30.0), 24.0 (17.0, 33.8) ( H=57.041, P<0.001); γ-glutamyl transferase (U/L) 135.0 (45.0, 364.0), 33.0 (23.5, 49.5), 32.0 (19.0, 49.0) ( H=82.558, P<0.001); however, there were no statistical significance in the pairwise comparisons between risky drinking and healthy groups. The two loci of ADH4 and ADH7 were in genetic linkage equilibrium. In the three groups of samples, the ADH4 gene rs1126671 locus was comprised primarily of the CC homozygous genotype, and there was no TT genotype. The ADH7 gene rs971074 genotype had statistical difference in the comparison of the three groups ( χ2=9.370, P<0.05). Compared with the CC genotype, the CT genotype had no statistical difference in the pairwise comparison between the risky drinking behavior group and alcoholic liver disease group, and the healthy group and alcoholic liver disease group. There was a statistical difference in that between the healthy group and the risky drinking behavior group ( χ2=6.372, P=0.012). The analysis display of mode of inheritance between RD group and HA group was statistically significant in the difference of the superdominance inheritance mode ( OR=2.92, 95% CI:1.22-6.98; P=0.012), the dominant inheritance mode ( OR=2.90, 95% CI:1.26-6.64; P=0.008), the co-dominant inheritance mode ( OR=2.96, 95% CI:1.24-7.08; P=0.032) and the additive mode ( OR=2.46, 95% CI:1.16-5.22; P=0.013). In general, the CT genotype of ADH7 gene rs971074 is a risk factor for positive risky drinking behavior, and the ADH family may still increase the susceptibility of people with a potential alcoholic liver disease protection background through the correlation between ADH7 and risky drinking behavior.

Interactions between brain-resident and peripheral infiltrated immune cells are thought to contribute to neuroplasticity after cerebral ischemia. However, conventional bulk sequencing makes it challenging to depict this complex immune network. Using single-cell RNA sequencing, we mapped compositional and transcriptional features of peri-infarct immune cells. Microglia were the predominant cell type in the peri-infarct region, displaying a more diverse activation pattern than the typical pro- and anti-inflammatory state, with axon tract-associated microglia (ATMs) being associated with neuronal regeneration. Trajectory inference suggested that infiltrated monocyte-derived macrophages (MDMs) exhibited a gradual fate trajectory transition to activated MDMs. Inter-cellular crosstalk between MDMs and microglia orchestrated anti-inflammatory and repair-promoting microglia phenotypes and promoted post-stroke neurogenesis, with SOX2 and related Akt/CREB signaling as the underlying mechanisms. This description of the brain's immune landscape and its relationship with neurogenesis provides new insight into promoting neural repair by regulating neuroinflammatory responses.

Objective:To investigate and distinguish the useful index of recognizing blood culture contamination and bloodstream infection when the blood cultures were positive in clinical practice, and to help clinicians to recognize blood culture contamination.Methods:A retrospective study was conducted to analyze the clinical data and distribution of bacteria of blood culture from 303 patients with positive blood culture from January to December 2021 in Huashan Hospital, Fudan University. Age, distribution of departments, positive time of blood culture, neutrophil ratio, procalcitonin and C-reactive protein (CRP) were compared between bloodstream infection group and blood culture contamination group. Mann-Whitney U test and chi-square test were used for statistical comparisons. The factors for recognizing blood culture contamination were analyzed by multivariate logistic regression. Results:A total of 303 patients with positive blood culture were enrolled and divided into two groups, including 237 cases in bloodstream infection group and 66 cases in blood culture contamination group, with the contamination rate of 21.78%. There was statistically significant difference in the distribution of departments between the two groups ( χ2=11.28, P=0.024). The proportion of age≥60 years old (52.7%(125/237) vs 36.4%(24/66)), the neutrophil ratio(0.86(0.79, 0.91) vs 0.82(0.75, 0.88)), the levels of procalcitonin (1.05(0.23, 6.64) μg/L vs 0.17(0.11, 0.72) μg/L) and CRP (60.55(24.83, 132.83) mg/L vs 40.64(8.98, 95.83) mg/L) in the bloodstream infection group were higher than those in blood culture contamination group, and the differences were statistically significant ( χ2=5.54, U=9 523.00, 10 906.00 and 9 278.50, respectively, all P<0.05). Among the 303 patients with positive blood culture, 253 patients had a single positive blood culture, 41 patients had twice positive blood cultures and nine patients had three times positive blood cultures. The highest contamination rate of detected pathogen was coagulase-negative staphylococcus (54.72%(29/53)) in the patients with single positive blood culture. The positive time of blood culture in the bloodstream infection group was 3(3, 4) d, which was shorter than 4(3, 4) d in the blood culture contamination group, and the difference was statistically significant ( U=6 521.00, P=0.026). Multivariate logistic regression analysis showed that when the time to positivity ≤3 days and procalcitonin level ≥2.00 μg/L, the positive blood culture results were more likely to be bloodstream infection (odds ratio ( OR)=2.16, 1.96, respectively, both P<0.05). Conclusions:Bacteria associated with blood culture, time to positivity and clinical index all play important roles in recognizing blood culture contamination. When the time to positivity ≤3 days and procalcitonin level ≥2.00 μg/L, the positive blood culture results are more likely to be bloodstream infection.
