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 association of systemic inflammatory response index (SIRI) with prognosis of coronary artery disease (CAD) patients has never been investigated in a large sample with long-term follow-up. This study aimed to explore the association of SIRI with all-cause and cause-specific mortality in a nationally representative sample of CAD patients from United States. METHODS: A total of 3386 participants with CAD from the National Health and Nutrition Examination Survey (NHANES) 1999-2018 were included in this study. Cox proportional hazards model, restricted cubic spline (RCS), and receiver operating characteristic curve (ROC) were performed to investigate the association of SIRI with all-cause and cause-specific mortality. Piece-wise linear regression and sensitivity analyses were also performed. RESULTS: During a median follow-up of 7.7 years, 1454 all-cause mortality occurred. After adjusting for confounding factors, higher lnSIRI was significantly associated with higher risk of all-cause (HR = 1.16, 95% CI: 1.09-1.23) and CVD mortality (HR = 1.17, 95% CI: 1.05-1.30) but not cancer mortality (HR = 1.17, 95% CI: 0.99-1.38). The associations of SIRI with all-cause and CVD mortality were detected as J-shaped with threshold values of 1.05935 and 1.122946 for SIRI, respectively. ROC curves showed that lnSIRI had robust predictive effect both in short and long terms. CONCLUSIONS SIRI was independently associated with all-cause and CVD mortality, and the dose-response relationship was J-shaped. SIRI might serve as a valid predictor for all-cause and CVD mortality both in the short and long terms.

Acute kidney injury (AKI) has high morbidity and mortality, but effective clinical drugs and management are lacking. Previous studies have suggested that macrophages play a crucial role in the inflammatory response to AKI and may serve as potential therapeutic targets. Emerging evidence has highlighted the importance of forkhead box protein O1 (FoxO1) in mediating macrophage activation and polarization in various diseases, but the specific mechanisms by which FoxO1 regulates macrophages during AKI remain unclear. The present study aimed to investigate the role of FoxO1 in macrophages in the pathogenesis of AKI. We observed a significant upregulation of FoxO1 in kidney macrophages following ischemia-reperfusion (I/R) injury. Additionally, our findings demonstrated that the administration of FoxO1 inhibitor AS1842856-encapsulated liposome (AS-Lipo), mainly acting on macrophages, effectively mitigated renal injury induced by I/R injury in mice. By generating myeloid-specific FoxO1-knockout mice, we further observed that the deficiency of FoxO1 in myeloid cells protected against I/R injury-induced AKI. Furthermore, our study provided evidence of FoxO1's pivotal role in macrophage chemotaxis, inflammation, and migration. Moreover, the impact of FoxO1 on the regulation of macrophage migration was mediated through RhoA guanine nucleotide exchange factor 1 (ARHGEF1), indicating that ARHGEF1 may serve as a potential intermediary between FoxO1 and the activity of the RhoA pathway. Consequently, our findings propose that FoxO1 plays a crucial role as a mediator and biomarker in the context of AKI. Targeting macrophage FoxO1 pharmacologically could potentially offer a promising therapeutic approach for AKI.

Objective To investigate the expression of microRNA-221-3p(miR-221-3p)in breast cancer cells under hypoxia conditions,and the effects of knocking down its expression on the stemness maintenance and angiogenesis in breast cancer cells.Methods Human breast cancer cell line MCF-7 were cultured under normoxic and hypoxic conditions,and the expression of miR-221-3p in cells was detected by quantitative real-time polymerase chain reaction(RT-qPCR).MCF-7 cells were divided into normoxic group(MCF-7 cells were cultured under normoxic conditions),hypoxic group(MCF-7 cells were cultured under hypoxic conditions),hypoxia+miR-221-3p NC group(MCF-7 cells were cultured under hypoxic conditions and transfected with miR-221-3p NC),hypoxia+miR-221-3p inhibitor group(MCF-7 cells were cultured under hypoxic conditions and transfected with miR-221-3p inhibitor).The proliferation activity of cells in each group was detected by CCK-8 method;the number of cell tumor spheres in each group was detected by tumor sphere formation assay;the proportion of cells labeled with the stemness marker aldehyde dehydrogenase 1(ALDH1)in each group was detected by flow cytometry;the expression of cluster of differentiation 133(CD133),cluster of differentiation 44(CD44)and sex determination region Y-box protein 2(SOX2)of cells in each group was detected by Western blot;the number of human umbilical vein endothelial cells(HUVEC)tubes formed by cell supernatant culture in each group was detected by in vitro tube formation experiment;the expression of hypoxia-inducible factor-1α(HIF-1α)and vascular endothelial growth factor(VEGF)of cells in each group was detected by Western blot.Results Compared with normoxic group,the expression levels of miR-221-3p,and CD133,CD44,SOX2,HIF-1α,VEGF protein of cells in hypoxic group were significantly up-regulated(P<0.05),and the cell proliferation activity,the number of tumor spheres,the proportion of ALDH1+cells and the number of HUVEC tubes were significantly increased(P<0.05).Compared with hypoxia+miR-221-3p NC group,the expression levels of miR-221-3p,and CD133,CD44,SOX2,HIF-1α,VEGF protein of cells in hypoxia+miR-221-3p inhibitor group were significantly down-regulated(P<0.05),and the cell proliferation activity,the number of tumor spheres,the proportion of ALDH1+cells,and the number of HUVEC were significantly decreased(P<0.05).Conclusion Under hypoxic conditions,the expression of miR-221-3p in breast cancer cells is up-regulated,and knocking down the expression of miR-221-3p can reduce the stemness and angiogenesis ability of breast cancer cells.

Objective:To explore the effect of hospital-community continuous management based on mobile health and dyadic coping intervention in ileostomy patients and their spouses.Methods:This was a randomized controlled trial. Patients with rectal cancer who underwent ileostomy at Taizhou People′s Hospital between August 2018 and August 2023, along with their spouses, were enrolled. Patient-spouse dyads were randomly assigned to either the intervention group or the control group using a random number table method. Baseline demographic data were collected from both groups. The control group received routine care, whereas the intervention group was given a hospital-community transitional care program based on mHealth (mobile health) and a dyadic coping model. Stoma adaptation, family functioning, and dyadic coping capacity were evaluated at 1 week, 1 month, and 3 months postoperatively. Sedentary behavior time and exercise compliance were also assessed at 1 month and 3 months after surgery.Results:A total of 47 patient-spouse dyads were included in the control group and 48 dyads in the intervention group. There were no statistically significant differences in baseline characteristics between the two groups (all P>0.05). Similarly, no significant differences were found in the age, sex or education level of the spouses (all P>0.05). At 1 week postoperatively, there were no significant differences in family cohesion and adaptability scores between the two groups (all P>0.05). However, at 1 and 3 months postoperatively, the intervention group had significantly higher family cohesion and adaptability scores than the control group (all P<0.05). With regard to dyadic coping capacity, no significant differences were observed in any of the subscale scores of the dyadic coping questionnaire at 1 week postoperatively (all P>0.05). At 1 and 3 months postoperatively, the intervention group scored significantly higher than the control group on stress communication, supportive coping, delegated coping, and joint coping ( P<0.05), but lower on negative coping ( P<0.05). In terms of stoma adaptation, no significant difference was found between the two groups at 1 week postoperatively ( P>0.05). At 1 and 3 months postoperatively, the intervention group showed significantly higher stoma adaptation and exercise compliance scores, as well as shorter sedentary behavior time, compared to the control group (all P<0.05). Conclusions:The hospital-community transitional care program developed by the research team effectively improves family functioning, dyadic coping capacity in ileostomy patient-spouse dyads, and postoperative stoma adaptation and rehabilitation outcomes.

Objective To investigate the efficacy and safety of self-help inflatable balloon in the treatment of refractory benign upper digestive tract stricture.Methods From November 2022 to February 2024,10 patients with refractory benign upper digestive tract stricture underwent self-help inflatable balloon were retrospectively analyzed.Preoperative treatment,intraoperative and postoperative complications,dysphagia score before and after surgery,wearing time of external self-help inflatable balloon,and the clinical efficacy were evaluated.Results All the 10 patients received self-help inflatable balloon treatment.No complications such as bleeding and perforation occurred in all patients during the wearing of the balloon.The placement time of the balloon was 60～180 d,and the average wearing time was 104.9 d.Before surgery,nine cases had a stricture segment length less than 2 cm,and one case had a stricture segment length of 6 cm.The dysphagia score before surgery was(3.60±0.52),and the dysphagia score after removal of the self-help inflatable balloon was(0.60±0.52),and there was statistical significance in preoperative and postoperative comparison(P＜0.05).The dysphagia score 3 months after removal of the external self-help inflatable balloon was(0.70±0.48),there was no significant difference in dysphagia score between the day after surgery and 3 months after surgery(P＞0.05).The diameter of the stricture before and after operation was(5.09±2.02)mm and(10.35±0.73)mm respectively,and the difference was statistically significant(P＜0.05).Sore throat,wing of nose pain and balloon displacement were the most common adverse events,with 30.0％(3/10),50.0％(5/10)and 70.0％(7/10),respectively.Conclusion It is safe,effective and feasible to treat refractory benign upper digestive tract stricture with self-help inflatable balloon in vitro.It is worthy for clinical application.

Objective To develop an erythrocyte-based delivery system for butyrylcholinesterase(BChE)that is capable of prophylaxis against organophosphorus nerve agents.Methods Recombinant BChE was produced and analyzed for oligomerization via polyacrylamide gel electrophoresis(PAGE)and Western blotting.A modified hypotonic preswelling method was employed to prepare BChE-loaded erythrocytes.The drug loading capacity and encapsulation efficiency were quantified using enzyme-linked immunosorbent assay(ELISA).Catalytic activity was assessed in vitro with an activity detection kit.The system was characterized via scanning electron microscopy(SEM),flow cytometry and a hematology analyzer.Results Recombinant BChE predominantly existed as dimers(85％dimer,15％monomer).The optimized volume ratio of erythrocytes to hypotonic solution was determined as 1:7.Compared with native and empty erythrocytes,BChE-loaded erythrocytes exhibited significantly higher catalytic activity(P＜0.001).The mean corpuscular volume of BChE-loaded erythrocytes increased(P＜0.001),while the mean content of corpuscular hemoglobin and hemoglobin in erythrocytes per 100 mL decreased(P＜0.001).SEM revealed no morphological differences(biconcave disc shape).Hypotonic preswelling moderately increased erythrocyte apoptosis(P＜0.001),but no statistical difference was observed between BChE-loaded and hypotonic-treated erythrocytes(P＞0.05).CD47 expression remained unchanged compared to native erythrocytes(P＞0.05).Conclusion The modified hypotonic preswelling method can generate BChE-loaded erythrocytes that retain the characteristics of native erythrocytes while conferring catalytic activity,offering a novel strategy for clinical intervention against organophosphorus poisoning.

Background:Bushen Zhuanggu Formula(BZF),derived from the classic Yougui Pills,has shown favorable clinical efficacy in treating advanced nontraumatic osteonecrosis of the femoral head(NONFH),particularly by promoting bone repair.However,its underlying mechanisms remain unclear.Objective:This study aimed to explore the mechanisms by which BZF promotes bone repair in advanced NONFH.Materials and methods:A total of 518 potential BZF targets were identified from the ETCM v2.0 database.Transcriptomic profiling of clinical cohorts revealed 485 differentially expressed genes in advanced NONFH patients compared to healthy controls.A drug target-disease gene interaction network was constructed to identify candidate BZF targets involved in NONFH pathogenesis.In vivo experiments were conducted to validate the effects of BZF in a rat model of advanced NONFH.Results:Network analysis identified key pathways associated with blood circulation obstruction,immune-inflammatory imbalance,and abnormal bone metabolism.Protein kinase C alpha(PKCA),Ras proto-oncogene(RAS),mitogen-activated protein kinase 3(ERK),ETS proto-oncogene 1(ETS1),and receptor activator of nuclear factor-κB ligand(RANKL)formed a signaling axis implicated in NONFH pathogenesis.BZF treatment alleviated joint inflammation,preserved trabecular bone morphology,reduced bone loss,and promoted bone repair.Mechanistically,BZF significantly downregulated the expression of PKCA,RAS,ERK,ETS1,and RANKL,improved blood circulation,and inhibited osteoclast activation while promoting osteoblast activation.Conclusion:BZF may promote bone repair in advanced NONFH by enhancing blood circulation and modulating the PKC-RAS-ERK-ETS1-RANKL signaling axis,thereby reversing dysregulated bone metabolism.
