Objective To analyze the relationship between umbilical cord blood chemokines regulated upon activation normal T cell expressed and secreted(RANTES),C-X-C motif chemokine ligand 12(CXCL12),C-X-C motif chemokine receptor 4(CXCR4)and neonatal septicemia inflammatory response and outcome.Meth-ods A total of 242 children with neonatal septicemia admitted to a hospital from January 2020 to January 2024 were selected as the study subjects,and were divided into non-critical group(101 cases),critical group(79 cases)and extremely critical group(62 cases)according to neonatal critical case score.According to the prognosis,the subjects were divided into good prognosis group and bad prognosis group.The levels of RAN-TES,CXCL12,CXCR4 and inflammatory factors[C-reactive protein(CRP),interleukin-6,IL-1β]in umbilical cord blood of each group were detected.The correlation between RANTES,CXCL12,CXCR4 and inflammato-ry factors in umbilical cord blood of neonatal septicemia was analyzed by Pearson correlation,and the influen-cing factors of poor prognosis of neonatal septicemia were analyzed by multivariate Logistic regression.Re-ceiver operating characteristic(ROC)curve was drawn to analyze the value of umbilical cord blood RANTES,CXCL12 and CXCR4 in predicting the poor prognosis of neonatal septicemia.Results The levels of RAN-TES,CXCL12,CXCR4,CRP,IL-6 and IL-1β in umbilical cord blood of extremely critical group were higher than those of critical group and non-critical group,and the differences were statistically significant(P＜0.05).The levels of RANTES,CXCL12 and CXCR4 in umbilical cord blood of neonatal septicemia were posi-tively correlated with CRP,IL-6 and IL-1β(P＜0.05).Multivariate Logistic regression analysis showed that extremely severe,early-onset septicemia,high RANTES,high CXCL12 and high CXCR4 were risk factors for poor prognosis of neonatal septicemia(P＜0.05).ROC curve analysis results showed that the area under the curve(AUC)of umbilical cord blood RANTES,CXCL12 and CXCR4 in predicting poor prognosis of neonatal septicemia were 0.810,0.814 and 0.763,respectively,and the AUC of three indicators combined prediction was 0.914,which was higher than that of single prediction.Conclusion The increased levels of RANTES,CX-CL12 and CXCR4 in umbilical cord blood of neonatal septicemia are associated with inflammation,aggravation and poor prognosis,and the combination of RANTES,CXCL12 and CXCR4 can predict the risk of poor prog-nosis of neonatal septicemia.

Objective To explore the diagnostic value of the combined detection of serum allograft inflammatory factor-1 (AIF-1), growth differentiation factor-15 (GDF15), and doublecortin-like kinase 1 (DCLK1) in breast cancer. Methods A total of 114 female breast cancer patients (breast cancer group) and 114 female volunteers (control group) who underwent physical examination were selected. Enzyme-Linked immunosorbent assay was applied to detect serum levels of AIF-1, GDF15, and DCLK1. Multivariate Logistic regression was used to analyze the risk factors affecting breast cancer. ROC curve was used to analyze the diagnostic value of serum AIF-1, GDF15, DCLK1 levels in breast cancer. Results The serum levels of AIF-1, GDF15, and DCLK1 in the breast cancer group were obviously higher than those of the control group (P<0.05). The expression levels of serum AIF-1, GDF15, and DCLK1 were significantly elevated in breast cancer patients with stage Ⅲ-Ⅳ, moderate and poor differentiation, lymph-node metastasis, and Ki-67 positive (P<0.05). Serum AIF-1, GDF15, and DCLK1 were risk factors for breast cancer, and the areas under the curve (AUC) for single and combined diagnosis of breast cancer for all three were 0.834, 0.753, 0.861, and 0.930, respectively. Additionally, the combined diagnosis AUC values were significantly higher than those assessed alone (Z_{combination-AIF-1}=3.479, Z_{combination-GDF15}=5.147, and Z_{combination-DCLK1}=3.121; all P<0.05). Conclusion In breast cancer patients, the serum AIF-1, GDF15, and DCLK1 levels increase. They are risk factors for breast cancer, and the combined diagnosis of the three is more effective.

OBJECTIVE To evaluate the effectiveness and safety of sequential therapy with parathyroid hormone analogues and bisphosphonates for osteoporosis. METHODS PubMed， Embase， the Cochrane Library， Web of Science， China National Knowledge Infrastructure， VIP， Wanfang data， and SinoMed were searched in both English and Chinese databases from their inception to March 25， 2024. Two researchers independently conducted literature searches， screening， and data extraction. Review Manager 5.4 software was used for the meta-analysis. Subgroup analyses and sensitivity analyses were performed based on different medication sequences in the treatment group to account for potential sources of heterogeneity. RESULTS A total of 7 randomized controlled trials involving 2 461 participants were included， with 1 215 in the treatment group and 1 246 in the control group. The meta-analysis results showed that the treatment group using sequential therapy with parathyroid hormone analogues and bisphosphonates had superior effects on improving bone mineral density at the lumbar spine [SMD＝0.90， 95%CI （0.44， 1.35）， P＜0.001]， total hip [SMD=0.68， 95%CI （0.14， 1.21）， P＝0.01]， and femoral neck [SMD＝0.45， 95%CI （0.04， 0.86）， P＝0.03] compared to the control group. It also significantly outperformed the control group in reducing the incidence of fractures post- treatment [OR＝0.72， 95%CI （0.54， 0.97）， P＝0.03].significant difference was noted in the incidence of adverse reactions between the two groups [OR＝1.21， 95%CI （0.99， 1.46）， P＝0.06]. Subgroup analysis based on intervention measures in the treatment group showed that switching from bisphosphonates to parathyroid hormone analogues [SMD＝0.56， 95%CI （0.09， 1.03）， P＝0.02] or switching from parathyroid hormone analogues to bisphosphonates [SMD＝0.97， 95%CI （0.49， 1.46）， P＜0.001] both significantly potentiated lumbar spine bone mineral density compared to the control group. Switching from bisphosphonates to parathyroid hormone analogues also significantly promoted total hip bone mineral density compared to the control group [SMD＝0.66， 95%CI （0.18， 1.13）， P＝0.007]. Sensitivity analysis indicated that the results of this study were robust. CONCLUSIONS Sequential therapy with parathyroid hormone analogues and bisphosphonates can be recommended as an effective treatment for patients with osteoporosis， with good safety profiles. The medication sequences should be individually adjusted based on the patient’s particular situation and the different responses of various skeletal sites.

The pathogenesis of urolithiasis is not yet clear， and there are obvious limitations in the prevention and treatment of urolithiasis by either Chinese or western medicine. The microscopic pathological changes of the kidney from anatomical perspective have a certain internal connection with viewpoint of “kidney storing insufficiency， and kidney deficiency as the root” in the traditional Chinese medicine （TCM） zang-fu （脏腑） theory. Accordingly， the prevention and treatment of urolithiasis by integrated traditional Chinese and western medicine based on “shen-kidney” theory has been proposed. It is believed that the prevention and treatment of urolithiasis can be divided into two stages， that is expelling stones and preventing stones. In terms of preventing stones from kideny， it is recommended to focus on the early pathological changes of the kidney； for preventing stones from shen， it is advised to prevent and treat urolithiasis from kidney deficiency. The treatment should be time-based and stage by stage. Adhering to the principle of “prevention before disease occurs， prevention is more important than treatment” aims to advance the intervention targets for the prevention and treatment of urolithiasis. Emphasizing on the simultaneous treatment of kidney disease and urolithiasis， it is critical to put focus on the development of calcium-containing crystalline nephropathy in the early stage of stone formation， as well as the fundamental pathogenesis of kidney deficiency in TCM. Shen-kidney theory aims to further promote the integration of traditional Chinese and western medicine in the prevention and treatment of urolithiasis， which may provide certain reference for solving the current dilemma of urolithiasis prevention and treatment.

Objective:To compare image quality and diagnostic parameters of whole-brain CT perfusion scans under different scanning conditions and assess the utility of deep learning image reconstruction algorithm (DLIR) in reducing tube current during low-dose scans.Methods:Method A total of 105 patients with suspected acute ischemic stroke (AIS) were prospectively enrolled in the First Affiliated Hospital of Zhengzhou University from March, 2022 to March, 203 and their baseline information was recorded. All patients underwent head non-contrast CT and CT perfusion (CTP) examinations. CTP scanning was performed at 80 kV in two groups with the tube current of 150 mA (regular dose) and 100 mA (low dose), respectively. The CTP images of 150 mA group were reconstructed using filtered back-projection algorithm as well as adaptive statistical iterative reconstruction-V (ASIR-V) at 40% and 80% strength levels, which were denoted as groups A-C. The CTP images of 100 mA group were reconstructed using ASIR-V80%, DLIR-M, and DLIR-H, which were denoted as groups D-F. Clinical baseline characteristics and radiation doses were compared between the two groups under different scanning conditions. Furthermore, we assessed the subjective and objective image quality, conventional perfusion parameters, and abnormal perfusion parameters of AIS patients across the six groups of reconstructed CTP images.Results:Under the scanning conditions of 150 mA and 100 mA, 47 and 48 patients were diagnosed with AIS, respectively. There were no significant differences in the baseline characteristics between the two groups. However, there was a significant difference in the mean effective radiation dose (5.71 mSv vs. 3.80 mSv, t = 2 768.30, P < 0.001). The standard deviation (SD) of noise, signal-to-noise ratio (SNR), and contrast-to-noise ratio (CNR) of gray matter (GM) and white matter (WM) were significantly different among the six groups of reconstructed images ( F = 40.58-212.13, P < 0.001). In GM, the SD values in groups C, D, and F were lower than those in other groups ( P < 0.05), and the SNR values in groups C and F were higher than those in other groups ( P < 0.05). In WM, the SD and SNR values in groups C and F were significantly different from those in other groups ( P < 0.05). Additionally, CNR values in groups C and F were higher than those in other groups ( P < 0.05). There was no significant difference in subjective scores among groups B, C, and F ( P > 0.05). Regarding perfusion parameters in the brain GM, groups D and E had lower cerebral blood volume (CBV) values compared to groups A to C ( P < 0.05), and group F had lower CBV values than group B ( P < 0.05). In the brain WM, group D had consistently lower mean transit time (MTT) values compared to the other groups ( P < 0.05). Notably, there were no significant differences in AIS lesion detection rates and relevant diagnostic parameters across the six image groups. Conclusions:Low-tube current CTP scan combined with the DLIR-H algorithm can enhance image quality without affecting perfusion parameters such as CBV and MTT, while reducing radiation dose by 30%. This algorithm can be routinely applied in brain CTP examinations.
