OBJECTIVE To compare the efficacy and safety of roxadustat versus recombinant human erythropoietin （rHuEPO）， each combined with intravenous iron supplementation， in the treatment of renal anemia （RA） in patients undergoing maintenance hemodialysis （MHD）. METHODS A retrospective analysis was conducted on the medical records of 152 patients diagnosed with RA and receiving MHD at the Affiliated Hospital of Southwest Medical University between January 2022 and June 2024. According to the treatment regimen， patients were divided into observation group （n＝72） and control group （n＝80）. Both groups of patients received MHD and intravenous iron therapy， with the observation group additionally receiving roxadustat and the control group receiving rHuEPO， both for a treatment duration of 12 weeks. Changes in anemia indicators， iron metabolism parameters， inflammatory markers， cardiac function parameters， quality of life scores before and after therapy， and adverse events during treatment were compared between the two groups. RESULTS After 12 weeks of treatment， both groups showed significant increase in hemoglobin， red blood cell count， hematocrit， serum iron， transferrin， total iron binding capacity， transferrin saturation， left ventricular ejection fraction， E/A ratio， cardiac output， 36-Item Short Form Health Survey score， and Kidney Disease Quality of Life Short Form score compared to baseline （P＜0.05）. Conversely， the levels of ferritin， C-reactive protein， interleukin-6， tumor necrosis factor-α， brain natriuretic peptide， and N-terminal pro-B-type natriuretic peptide were significantly reduced （P＜0.05）. The improvements in the observation group were significantly greater than those in the control group （P＜ 0.05）. Moreover， the incidence of adverse events was significantly lower in the observation group compared to the control group （P＜0.05）. CONCLUSIONS Compared to rHuEPO combined with intravenous iron supplementation， roxadustat combined with intravenous iron supplementation is more effective in improving anemia， iron metabolism， inflammatory status， cardiac function， and quality of life in patients with RA undergoing MHD. Additionally， it demonstrates a better safety profile.

Objective To explore the clinical effectiveness of full endoscopic lamina fenestration discec-tomy(Endo-LOVE)in combination with nerve root pulsed radiofrequency(NR-PRF)in the treatment of lumbar degenerative disease(LDD),along with the amelioration of postoperative residual symptoms.Methods A retro-spective analysis was performed on 102 patients with LDD who were treated in our hospital between January 2022 and June 2023.Among them,53 cases were assigned to the observation group(receiving Endo-LOVE combined with NR-PRF),and 49 cases were included in the control group(undergoing Endo-LOVE alone).The mean follow-up period was 15.05±1.15 months.The general data of the two groups were compared.Observations were carried out at preoperative,1-day,7-day,1-month,3-month,6-month,and final follow-up time points postopera-tively.The perioperative data and follow-up outcomes of the two groups were compared.Results Prior to surgery,no significant disparities were detected in the general conditions and clinical observation indicators(VAS,M-JOA,and ODI scores)between the two groups.Postoperatively,both groups exhibited a notable improvement in clinical indicators when compared to the preoperative levels(P<0.05).Within three months after surgery,the observation group showed significantly more pronounced improvement in all clinical indicators than the control group(P<0.05).At six months postoperatively and during the final follow-up,no statistically significant differences in clinical indi-cators were found between the two groups.Moreover,at the final follow-up,there was no statistically significant difference in the Macnab scores between the two groups(P>0.05).Conclusion Endoscopic decompression for the treatment of LDD exhibits high safety and reliability.When combined with endoscopic NR-PRF,it enhances the clinical efficacy,reduces the incidence of postoperative residual symptoms,and facilitates rapid postoperative recovery.This complementary combination presents a novel therapeutic strategy for LDD.

ObjectiveTo explore the possible mechanisms of Wenyang Huazhuo Formula （温阳化浊方， WHF） in improving reproductive aging from the perspective of the ovarian mechanical microenvironment. MethodsThe experiment included five groups， 3-month group （20 female mice at 3 months of age）， 6-month group （20 female mice at 6 months of age）， 6-month + WHF group （20 female mice at 5 months of age treated with WHF）， 9-month group （20 female mice at 9 months of age）， and 9-month + WHF group （20 female mice at 8 months of age treated with WHF）. The 6-month + WHF group and 9-month + WHF group were orally administered WHF 41.2 g/（kg·d） once daily for 4 consecutive weeks. The other three groups received no intervention. Reproductive hormone levels were measured by ELISA. HE staining was used to count the numbers of various stages of follicles. Ovarian hyaluronic acid （HA） content and collagen fiber content were measured to evaluate the ovarian mechanical microenvironment. Superovulation was performed to observe the number of eggs obtained， as well as the number of offspring and birth weight to assess fertility. The in vitro fertilization and blastocyst culture of oocytes from female offspring in each group were observed to evaluate the effect of WHF on offspring reproductive potential. ResultsCompared with the 3-month group， the 6-month group and 9-month group showed significantly decreased serum levels of gonadotropin-releasing hormone （GnRH）， follicle-stimulating hormone （FSH）， and luteinizing hormone （LH）， decreased ovarian collagen content， and reduced numbers of primordial and secondary follicles. In contrast， the numbers of primary follicles， antral follicles， and atretic follicles increased. The levels of anti-Müllerian hormone （AMH）， ovarian HA content， and the fertilization rate， cleavage rate， and blastocyst formation rate of oocytes from offspring were significantly lower （P＜0.05）. Compared with the 6-month group， the 6-month + WHF group showed significantly reduced serum levels of GnRH， FSH， and LH， with a significant decrease in primary follicles， antral follicles， and atretic follicles as well as increase of AMH levels， ovarian HA content， number of primordial and secondary follicle， egg count， and offspring birth weight （P＜0.05）. Compared with the 9-month group， the 9-month + WHF group exhibited reduced GnRH， FSH， and collagen fiber content， as well as reduced number of primary follicles， antral follicles， and atretic follicles. However， AMH levels， ovarian HA content， number of primordial and secondary follicle， egg count， offspring numbers， birth weight， fertilization rate， cleavage rate， and blastocyst formation rate of oocytes from offspring all significantly increased （P＜0.05）. ConclusionWHF can significantly improve the ovarian reserve， fertility， and reproductive potential in offspring during reproductive mid-life and late-life stages. Its effect may be related to the remodeling of the mechanical microenvironment of aging ovaries. Moreover， the effect on the mechanical microenvironment remodeling of late-stage ovaries and the improvement of the offspring reproductive potential is more significant.

Acute lung injury(ALI) is a critical clinical condition primarily characterized by refractory hypoxemia and infiltration of inflammatory cells in lung tissue, which can progress into a more severe form known as acute respiratory distress syndrome(ARDS). Immune cells and inflammatory cytokines play important roles in the progression of the disease. Due to its unclear pathogenesis and the lack of effective clinical treatments, ALI is associated with a high mortality rate and severely affects patients' quality of life, making the search for effective therapeutic agents particularly urgent. Ginseng Radix et Rhizoma, the dried root of the perennial herb Panax ginseng from the Araliaceae family, contains active ingredients such as saponins and polysaccharides, which possess various pharmacological effects including anti-tumor activity, immune regulation, and metabolic modulation. In recent years, studies have shown that ginsenosides exhibit notable effects in reducing inflammation, ameliorating epithelial and endothelial cell injury, and providing anticoagulant action, indicating their comprehensive role in alleviating lung injury. This review summarizes the pathogenesis of ALI and the molecular mechanisms through which ginsenosides act at different stages of ALI development. The aim is to provide a scientific reference for the development of ginsenoside-based drugs targeting ALI, as well as a theoretical basis for the clinical application of Ginseng Radix et Rhizoma in the treatment of ALI.

Spine fracture and dislocation are common traumatic spinal conditions that often require surgical intervention due to compromised spinal stability. Surgical approaches include anterior, posterior, and combined anterior-posterior spinal procedures. According to the specific surgical requirements, patients may be placed in the prone position or repositioned between prone and supine positions during surgery. Intraoperative repositioning has become an essential step in patient positioning. However, during repositioning, patients with spinal fracture and dislocation are at increased risk for complications such as hemodynamic instability, nerve injury, and pressure injuries to the skin and soft tissue. Notably, due to the instability of the spinal cord, even minor manipulations can further exacerbate the damage, potentially leading to severe outcomes like paraplegia. Although the current clinical guidelines provide instructive recommendations for standard position, there remains no specific protocols for intraoperative repositioning in patients with spine fracture and dislocation. With a concern for the lack of clinical studies on positioning techniques, risk prevention, and operational norms for special patients, no applicable guidelines or standards are available. A consensus was required to provide clinical reference, meet the requirements of surgical treatment, and minimize the safety risks of patients caused by improper placement of positions. Professional Committee of Operating Room Nursing of Shaanxi Nursing Association organized experts in nursing management and operating room nursing from major hospitals across China to formulate Expert consensus on intraoperative repositioning for patients with spinal fracture and dislocation ( version 2025). The consensus provides 11 recommendations covering pre-repositioning preparation, intraoperative maneuvers, and post-repositioning observation, aiming to provide references for clinical standardization of the intraoperative repositioning process and protection of patients′ safety.

BACKGROUND:Neuropilin 1 plays a critical role in fracture healing,especially in osteogenesis-angiogenesis coupling. Osteogenesis-coupled angiogenesis is vital for fracture healing,including angiogenesis and bone formation (especially H-type vessel formation) and their association. OBJECTIVE:To review the research progress of neuropilin 1 in promoting osteogenesis-coupled angiogenesis during fracture healing.METHODS:The literature search was performed in the PubMed and Chinese National Knowledge Infrastructure databases for articles published from January 1982 to April 2024 using the search terms "Neuropilin-1,neuropilin 1,NRP1,neuropilin-1,NRP-1,Neuropilin 1,Nrp1,Nrp-1." We identified 43 articles associated with fracture healing,H-type vessels,arteries,bone cells,and angiogenesis-osteogenesis coupling. Moreover,24 articles were searched manually. Finally,67 papers were included.RESULTS AND CONCLUSION:(1) Angiogenesis,osteoblastogenesis,and their association were critical for angiogenesis-osteogenesis coupling during fracture healing. Especially H-type vessel formation was critical during fracture healing. H-type vessels consisted of endothelial cells and pericytes. Osteoblasts,osteoclasts,chondrocytes,and other skeletal cells were critical contributors to new bone formation. (2) Neuropilin 1 enhanced endothelial cell migration and stabilization,increased stability of endothelial cells and pericytes,and strengthened the link of endothelial cells and pericytes to initiate angiogenesis by vascular endothelial growth factor and platelet-derived growth factor. (3) Neuropilin 1 promoted bone regeneration by suppressing osteoclastogenesis and enhancing osteoclasts and chondrocyte formation. (4) Neuropilin 1 was a key factor in angiogenesis-osteogenesis coupling. (5) Topical application of neuropilin 1 and relative biologics,and combination neuropilin 1,nano drug-loading systems,and polymerized smart materials provided a new idea for treatment of fractures and hold great promise for extensive applications.

OBJECTIVE: To investigate the relationship between peripheral blood T-cell immunoglobulin mucin-3 (TIM-3) and iron overload in patients with myelodysplastic syndrome (MDS) undergoing red blood cell transfusion. METHODS: 120 MDS patients who received treatment at Wuhan Third Hospital from June 2020 to May 2022 were included and analyzed as research subjects, all of whom met the indications for red blood cell transfusion. Blood routine and biochemical indicators were tested before transfusion, and general clinical data of the patients were statistically analyzed. The iron metabolism status of the patients were evaluated. The clinical characteristics of patients with iron overload and the factors affecting iron overload were analyzed. And a correlation analysis was conducted between TIM-3 and other factors affecting iron overload. RESULTS: Among the 120 MDS patients included in this study, 82 cases (68.33%) were detected to have iron overload after red blood cell transfusion. The occurrence time of iron overload was 20-42 weeks, with an average time of 32.35±5.26 weeks, calculated from the first transfusion of red blood cells. The proportion of patients with high-risk and extremely high-risk according to the revised International Prognostic Scoring System (IPSS-R) and WHO classification-based Prognostic Scoring System (WPSS), the volume of blood transfusions, the proportion of transfusion-dependent patients, and the levels of serum hepcidin (Hepc), erythropoietin (EPO), and TIM-3 in patients with iron overload were higher than those in patients with normal iron metabolism, and the differences were statistically significant (P < 0.05). Logistic regression analysis showed that high-risk and extremely high-risk according to WPSS, blood transfusion volume, transfusion dependence, and upregulation of serum Hepc, EPO, and TIM-3 expression were factors affecting iron overload in MDS patients undergoing red blood cell transfusion (P < 0.05). Pearson correlation analysis showed that serum TIM-3 level in MDS patients were positively correlated with the other factors affecting iron overload (P < 0.05). CONCLUSION Serum TIM-3 is associated with iron overload in MDS patients undergoing red blood cell transfusion, and upregulation of serum TIM-3 expression increases the risk of iron overload after red blood cell transfusion.

OBJECTIVE: To analyze the correlation between the expression levels of Tim-3, C-myc and the proportion of T lymphocyte subsets and prognosis in patients with acute lymphoblastic leukemia (ALL). METHODS: The research group selected 60 ALL patients admitted to our hospital from December 2019 to December 2021, while the control group selected 55 healthy volunteers who underwent physical examination in our hospital. The expression levels of Tim-3, C-myc mRNA and the proportion of T lymphocyte subsets in the two groups were detected. The mortality rate of ALL patients was calculated, and the correlation between the expression levels of Tim-3, C-myc, and the proportion of T lymphocyte subsets and pathological features and prognosis was analyzed. RESULTS: Compared with the control group, the levels of Tim-3, C-myc and CD8⁺ in the research group were increased, while the levels of CD3⁺ , CD4⁺ and CD4⁺ /CD8⁺ were decreased (all P < 0.001). The levels of Tim-3, C-myc mRNA, CD3⁺ , CD4⁺ , CD8⁺ , CD4⁺ /CD8⁺ were correlated with risk classification and extramedullary infiltration (all P < 0.05). The survival rate of patients with low expression of Tim-3, C-myc, and CD8⁺ was higher than that of patients with high expression, while the survival rate of patients with high expression of CD3⁺ , CD4⁺ , and CD4⁺ /CD8⁺ was higher than that of patients with low expression (all P < 0.05). Univariate analysis showed that the deceased patients had higher proportions of extramedullary infiltration and high-risk classification, as well as higher levels of Tim-3, C-myc, and CD8⁺ , while lower levels of CD3⁺ , CD4⁺ , and CD4⁺ /CD8⁺ compared with surviving patients (all P < 0.01). Multivariate logistic regression analysis showed that extramedullary invasion, risk classification, Tim-3, C-myc, CD3⁺ , CD4⁺ , CD8⁺ , CD4⁺ /CD8⁺ were the main factors affecting the prognosis of ALL patients (all P < 0.05). ROC curve analysis showed that the combination of Tim-3, C-myc, and T lymphocyte subsets had higher sensitivity and accuracy in predicting prognosis of ALL patients compared with the single diagnosis of Tim-3, C-myc, CD3⁺ , CD4⁺ , CD8⁺ , and CD4⁺ /CD8⁺ (P < 0.05). CONCLUSION ALL patients show higher levels of Tim-3, C-myc mRNA and CD8⁺ but lower levels of CD3⁺ , CD4⁺ and CD4⁺/CD8⁺. Moreover, the expression levels of Tim-3, C-myc, CD3⁺ , CD4⁺ , CD8⁺ and CD4⁺/CD8⁺ are correlated with extramedullary invasion, high-risk classification and prognosis.

OBJECTIVE: To evaluate the effect and safety of Chinese medicine (CM) Fuzheng Huazhuo Decoction (FHD) in treating patients with coronavirus disease 2019 (COVID-19) who persistently tested positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). METHODS: This retrospective cohort study was conducted at Shanghai New International Expo Center shelter hospital in China between April 1 and May 30, 2022. Patients diagnosed as COVID-19 with persistently positive SARS-CoV-2 reverse transcription-polymerase chain reaction (RT-PCR) test results for ⩾8 days after diagnosis were enrolled. Patients in the control group received conventional Western medicine (WM) treatment, while those in the FHD group received conventional WM plus FHD for at least 3 days. The primary outcome was viral clearance time. Secondary outcomes included negative conversion rate within 14 days, length of hospital stay, cycle threshold (Ct) values of the open reading frame 1ab (ORF1ab) and nucleocapsid protein (N) genes, and incidence of new-onset symptoms during hospitalization. Adverse events (AEs) that occurred during the study period were recorded. RESULTS: A total of 1,765 eligible patients were enrolled in this study (546 in the FHD group and 1,219 in the control group). Compared with the control group, patients receiving FHD treatment showed shorter viral clearance time for nucleic acids [hazard ratio (HR): 1.500, 95% confidence interval (CI): 1.353-1.664, P<0.001] and hospital stays (HR: 1.371, 95% CI: 1.238-1.519, P<0.001), and a higher negative conversion rate within 14 days (96.2% vs. 82.6%, P<0.001). The incidence of new-onset symptoms was 59.5% in the FHD group, similar to 57.8% in the control group (P>0.05). The Ct values of ORF1ab and N genes increased more rapidly over time in the FHD group than those in the control group post-randomization (ORF1ab gene: β =0.436±0.053, P<0.001; N gene: β =0.415 ±0.053, P<0.001). The incidence of AEs in the FHD group was lower than that in the control group (24.2% vs. 35.4%, P<0.001). No serious AEs were observed. CONCLUSION FHD was effective and safe for patients with persistently positive SARS-CoV-2 PCR tests. (Registration No. ChiCTR2200063956).
