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 investigate the safety and effectiveness of suctioning flexible ureteroscopy with intelligent pressure-control at different times after drainage for patients with urogenic sepsis complicated with upper urinary tract stones. 【Methods】 Clinical data of 59 patients treated in the Department of Urology, Affiliated Hospital of Nantong University during May 2022 and May 2023 were collected.The patients were divided into early lithotripsy (≤1 week) group (n=27) and late lithotripsy (>1 week) group (n=32).Baseline data, imaging data and postoperative data of the two groups were compared. 【Results】 There were no significant differences between the two groups in the stone-free rate, total incidence of complications, incidence of high-grade complications, length of stay after lithotripsy, hospitalization costs after lithotripsy and total hospitalization costs (P>0.05). 【Conclusion】 Both early lithotripsy (<1 week) and late lithotripsy (>1 week) are safe and effective in the treatment of urogenic sepsis after drainage.

Objective:To evaluate the relationship between the mechanism by which aucubin improved attention deficit hyperactivity disorder (ADHD) induced by maternal exposure to S-ketamine and GABAergic neurons in the habenular nucleus of offspring mice.Methods:SPF healthy C57BL/6 wild-type pregnant mice were used in this study, and an ADHD model in offspring mice was established by intraperitoneally injecting S-ketamine in the middle and late pregnancy. Twenty-four offspring of pregnant mice exposed to S-ketamine were divided into 2 groups ( n=12 each) at 14 days after birth using a random number table method: ADHD + normal saline group (AN group) and ADHD + aucubin group (AA group). Twenty-four offspring of pregnant mice exposed to normal saline were divided into 2 groups ( n=12 each) at 14 days after birth by a random number table method: control + normal saline group (CN group) and control + aucubin group (CA group). Aucubin 40 mg/kg was intraperitoneally injected once a day for 7 consecutive days in CA group and AA group, and the equal volume of normal saline was given instead in CN group and AN group. At 14 days after birth, the 16-channel microfilament array electrode was placed in the habenular nucleus, and the ratio of excitatory neurons to inhibitory neurons in the habenular nucleus was recorded when the mice buried beads in the marble burying test. At 21 days after birth (after the end of peritoneal administration), the impulsive and stereotypical behaviors of offspring mice were evaluated by elevated zero maze and marble burying test, respectively, and then the expression of glutamate decarboxylase 2 (GAD2) in habenular nucleus was detected by the immunofluorescence method. Results:Compared with CN group, the ratio of excitatory neurons to inhibitory neurons in the habenular nucleus was significantly increased, the expression of GAD2 was down-regulated, the time spent in the open arm was prolonged, the number of entries into the open arm and the number of buried beads were increased in AN group ( P<0.05), and no statistically significant differences were found in the above indexes in CA group ( P>0.05). Compared with AN group, the ratio of excitatory neurons to inhibitory neurons in the habenular nucleus was significantly decreased, the expression of GAD2 was up-regulated, the time spent in the open arm was shortened, and the number of entries into the open arm and the number of buried beads were decreased in AA group ( P<0.05). Conclusions:The mechanism by which aucubin alleviates prenatal S-ketamine exposure-induced ADHD may be related to increasing the number of GABAergic neurons in the habenular nucleus of offspring mice.
