ObjectiveThis study aimed to elucidate the specific molecular mechanism by which PAGE5 promotes breast cancer cell invasion and hepatic metastasis through regulating the PI3K/AKT signaling pathway and its downstream effector， matrix metalloproteinase 1 （MMP1）. MethodsBioinformatics analysis using the TCGA database was performed to evaluate PAGE5 expression in metastatic breast cancer tissues. The effects of PAGE5 on the proliferation， migration， and invasion capabilities of breast cancer cells were analyzed using CCK-8， EdU， Transwell， and wound healing assays. A splenic injection hepatic metastasis model in NOD-SCID mice was employed to validate the impact of PAGE5 on breast cancer liver metastasis. Transcriptome sequencing and KEGG enrichment analysis were conducted to identify potential signaling pathways regulated by PAGE5. Western blot was used to detect AKT phosphorylation levels. Quantitative real-time polymerase chain reaction （qPCR） was applied to screen and validate downstream target molecules of PAGE5. ResultsBioinformatic analysis revealed that PAGE5 expression was significantly upregulated in distant metastasis of breast cancer. Both in vitro and in vivo experiments confirmed that PAGE5 overexpression markedly enhanced the migration and invasion abilities of breast cancer cells and promoted the formation of liver metastatic lesions， whereas PAGE5 knockdown suppressed breast cancer liver metastasis （P＜0.000 1）. Transcriptome sequencing and KEGG enrichment analysis indicated that PAGE5 significantly activated the PI3K-AKT signaling pathway （P=0.028 5）. Western blot confirmed that PAGE5 upregulated p-AKT levels， which could be reversed by MK2206. The qPCR results confirmed that MMP1 is a key downstream effector of PAGE5， and its expression can be inhibited by MK2206 （P＜0.000 1）. ConclusionsThis study preliminarily demonstrates that PAGE5 can activate the PI3K/AKT signaling pathway and mediate the invasion and liver metastasis of breast cancer through MMP1.

Jiuwei Xifeng Granules have become a Chinese patent medicine in the market. Because the formula contains Os Draconis, a top-level protected fossil of ancient organisms, the formula was to be improved by replacing Os Draconis with Ostreae Concha. To evaluate whether the improved formula has the same effectiveness and safety as the original formula, a randomized, double-blind, parallel-controlled, equivalence clinical trial was conducted. This study enrolled 288 tic disorder(TD) of children and assigned them into two groups in 1∶1. The treatment group and control group took the modified formula and original formula, respectively. The treatment lasted for 6 weeks, and follow-up visits were conducted at weeks 2, 4, and 6. The primary efficacy endpoint was the difference in Yale global tic severity scale(YGTSS)-total tic severity(TTS) score from baseline after 6 weeks of treatment. The results showed that after 6 weeks of treatment, the declines in YGTSS-TSS score showed no statistically significant difference between the two groups. The difference in YGTSS-TSS score(treatment group-control group) and the 95%CI of the full analysis set(FAS) were-0.17[-1.42, 1.08] and those of per-protocol set(PPS) were 0.29[-0.97, 1.56], which were within the equivalence boundary [-3, 3]. The equivalence test was therefore concluded. The two groups showed no significant differences in the secondary efficacy endpoints of effective rate for TD, total score and factor scores of YGTSS, clinical global impressions-severity(CGI-S) score, traditional Chinese medicine(TCM) response rate, or symptom disappearance rate, and thus a complete evidence chain with the primary outcome was formed. A total of 6 adverse reactions were reported, including 4(2.82%) cases in the treatment group and 2(1.41%) cases in the control group, which showed no statistically significant difference between the two groups. No serious suspected unexpected adverse reactions were reported, and no laboratory test results indicated serious clinically significant abnormalities. The results support the replacement of Os Draconis by Ostreae Concha in the original formula, and the efficacy and safety of the modified formula are consistent with those of the original formula.

BACKGROUND: The benefits of ideal cardiovascular-health metrics (ICVHMs) in patients with renal insufficiency remain unclear. This study aimed to investigate the associations between ICVHM and prognosis in a renal insufficiency population. METHODS: The trial enrolled 29,682 participants from the US National Health and Nutrition Examination Survey (NHANES), 2007-2018, with mortality follow-up through December 31, 2019. Participants were divided into three groups based on estimated glomerular filtration rates. Cardiovascular health was assessed using new "Life's Essential 8" metrics. Cox regression analyses based on NHANES data were used to determine the associations between ICVHMs and cardiovascular mortality in patients with renal insufficiency. RESULTS: During a mean follow-up of 6.58 years, ideal cardiovascular health (hazard ratio [HR] = 0.42; 95% confidence interval [CI]; 0.25-0.70) and ideal health behavior (HR = 0.53; 95% CI; 0.39-0.73) reduced cardiovascular mortality in participants with renal insufficiency. For each one ICVHM increment, a 25% reduction in cardiovascular mortality was recorded (95% CI; 0.69-0.82). When compared with participants with normal renal function, for those with mild renal insufficiency, the HR for cardiovascular mortality gradually decreased from 1.47 (95% CI; 0.85-2.52) in those who had ≤1 ICVHMs to 0.30 (95% CI; 0.12-0.77) in participants who had >6 ICVHMs. CONCLUSIONS From an ICVHM perspective, enhanced cardiovascular benefits were observed in individuals with renal insufficiency, coupled with a reduced risk of all-cause mortality. Furthermore, when compared with individuals with normal renal function, increased ICVHMs can mitigate adverse risks associated with renal impairment.

Objective To analyze the impact of tandem mass spectrometry(MS/MS)screening compared to the indanone-fluorescence method(hereinafter referred to as fluorescence analysis)on finance or health insurance in screening newborn genetic metabolic diseases in Shanghai,and provide policy recommendations for MS/MS reimbursement.Methods A budget impact analysis model was constructed using Microsoft Excel 2019,with a study period of 3 years(2025?2027).Newborns of 2025 to 2027 were predicted based on the birth data of newborns in Shanghai and the average decrease of newborns in Shanghai.Clinical screening data and cost data were derived from relevant statistical websites,literature,and hospital survey data.Additionally,consultations with experts were conducted to understand national and Shanghai-specific screening and reimbursement policies.Among these,the fluorescence-based analysis method is primarily used for screening phenylketonuria,while MS/MS can be used for screening a variety of newborn genetic and metabolic disorders.So we separately calculated the impact of MS/MS screening compared to the fluorescence-based method on Shanghai's fiscal budget and health insurance fund.Results The budget impact analysis on fiscal expenditures indicates that from 2025 to 2027,the fiscal expenditures for fluorescence analysis will be 1.58 million,1.48 million and 1.39 million yuan,respectively.In contrast,MS/MS fiscal expenditures will be 22.75 million,21.37 million,and 20.06 million yuan,respectively;compared with fluorescence analysis,the increased fiscal expenditures for MS/MS will be 21.18 million,19.88 million,and 18.67 million yuan,respectively,showing a decreasing trend annually.The budget impact on health insurance funds shows that from 2025 to 2027,the expenditures for fluorescence analysis will be 1.11 million,1.04 million and 0.97 million yuan,respectively;MS/MS health insurance fund expenditures will be 15.93 million,14.96 million and 14.04 million yuan,respectively.Compared with fluorescence analysis,the additional health insurance fund expenditures for MS/MS will be 14.82 million,13.92 million and 13.07 million yuan,respectively,also showing a decreasing trend annually.Policy-wise,the costs for tandem mass spectrometry screening are typically covered by fiscal payments or out-of-pocket by patients,with commercial insurance,charitable foundations,and other organizations serving as supplementary sources of funding.Conclusion The overall cost of expanding newborn screening for genetic metabolic diseases in Shanghai is controllable.To unify the payment standards and facilitate centralized management,it is recommended that the costs for tandem mass spectrometry screening in Shanghai be covered by government funding.

Objective:To explore the short-term clinical effects of deep cervical lymph node-venous anastomosis in the treatment of Alzheimer’s disease (AD).Methods:A prospective exploratory study was conducted on the treatment of AD patients using the cervical deep lymph node-venous anastomosis technique in Scar and Wound Treatment Department, Plastic Surgery Hospital, Chinese Academy of Medical Sciences, from September to October 2024. The patients underwent high-frequency ultrasound to locate deep cervical lymph nodes and the external jugular vein. Under general anesthesia, bilateral deep cervical lymph node-venous anastomoses were performed. Indocyanine green (ICG) lymphography was conducted via subcutaneous injection behind the ear to visualize lymph nodes in levels Ⅱ and Ⅲ. After making a skin incision along the posterior margin of the sternocleidomastoid muscle, the external jugular vein, internal jugular veins, and associated lymph nodes were exposed. Adjacent veins were selected for anastomosis of lymph node. Using microsurgical techniques, end-to-side or end-to-end anastomosis was completed for lymph nodes in levels Ⅱ and Ⅲ. Preoperative assessments included the mini-mental state examination (MMSE, a higher score indicates better cognitive function), Alzheimer’s disease assessment scale-cognitive subscale (ADAS-Cog, a higher score indicates greater impairment of cognitive function), Alzheimer’s disease cooperative study scale for activities of daily living (ADCS-ADL, a higher score indicates better ability to perform daily activity), and neuropsychiatric inventory (NPI, a higher score indicates more severe behavioral and emotional symptom). Postoperative follow-up included the same scales to observe changes in cognitive function, activities of daily living, and emotional communication.Results:Four patients (1 male, 3 females, aged 58-79 years) with AD were included. All were diagnosed based on cerebrospinal fluid biomarkers. All patients successfully underwent bilateral deep cervical lymph node-venous anastomoses. On average, 4.3 (2-7 per person) anastomoses were performed per patient. Surgical procedures lasted an average of 6.5 h (5.5-8.5 h) with minimal blood loss (less than 50 ml). Patients resumed normal activity within 6 hours postoperatively and were discharged after an average of 4.1 d (3.5-5.0 d). Postoperative complications included one case each of aspiration pneumonia, lower limb venous thrombosis, and transient delirium, all of whom resolved without long-term effects. Clinical symptoms, including memory decline, mood swings, and anxiety, showed varying degrees of improvement. Patients reported enhanced quality of life, emotional stability, and social engagement, confirming the procedure’s safety and potential cognitive benefits. At one month postoperatively, the MMSE scores of the four patients increased by an average of 0.8 points compared to preoperative levels. Additionally, the two patients who completed the ADAS-Cog assessments showed a decrease in their scores (reduced by 1.0 points and 11.3 points, respectively, compared to preoperative scores), indicating a certain degree of improvement in cognitive function during this period. The ADCS-ADL and NPI scores of four patients varied significantly, without showing any clear pattern.Conclusion:Lymphovenous anastomosis of the deep cervical lymph node-venous anastomosis may provide a new surgical intervention approach for AD, but further large-scale studies and long-term follow-up are needed to validate its safety and effectiveness.
