Objective: To compare the effectiveness of the uniportal bichannel dual-media spinal endoscopic technique (UBD-TLIF) with open transforaminal lumbar interbody fusion (O-TLIF) for the treatment of lumbar disc herniation (LDH) with lumbar instability in older patients aged ≥65 years. Methods: This retrospective study included 64 older patients with LDH and lumbar instability who were admitted to Shanghai Tenth People Hospital between January 2023 and June 2025. General surgical parameters, perioperative pain levels, pre- and postoperative back and leg pain scores, functional outcomes, complication status, and lumbar spine stability were recorded and analyzed. Results: In the UBD-TLIF group, intraoperative blood loss was significantly lower than in the O-TLIF group. The UBD-TLIF group also demonstrated shorter incision length, reduced bed rest duration, and a shorter hospital stay compared with the O-TLIF group (p<0.05). Postoperatively, patients in the UBD-TLIF group showed significant improvement in visual analogue scale and Oswestry Disability Index scores (p<0.001). No complications were observed in either group. Conclusion Both UBD-TLIF and O-TLIF improved lumbar function in older patients with LDH and lumbar instability and demonstrated acceptable safety profiles. Compared with O-TLIF, UBD-TLIF, characterized by a smaller incision, was associated with reduced intraoperative blood loss, decreased early postoperative pain, and accelerated early recovery.

Blood deficiency syndrome (BDS) refers to a pathological state with blood dysfunction and organ dystrophy in traditional Chinese medicine. Danggui Wuji granules (DWG) was developed from a formula containing Angelicae Sinensis Radix and Musculus et Os Galli Domestici. Herein, we investigated the mechanism of DWG in treating BDS by modulating gut microbiota. We found that DWG protected mice from BDS by elevating the levels of red blood cell count, hemoglobin, and hematocrit in peripheral blood and increasing the erythrocyte membrane Na⁺-K⁺-ATPase activity. Danggui Wuji granules changed the composition and metabolites of colonic flora. Notably, Lactobacillus, Muribaculaceae, and Alistipes were the main genera showing changes after DWG treatment. Our findings revealed that DWG presented a positive therapeutic effect on BDS in mice by regulating the gut microbiota and metabolites. The protective mechanism of DWG was associated with pathways such as metabolic pathways, biosynthesis of secondary metabolites, ABC transporters, ribosome, thyroid hormone synthesis, lysine degradation, galactose metabolism, tyrosine metabolism, etc.

The structure of N-glycans on specific proteins can regulate innate and adaptive immunity via sensing environmental signals. Meanwhile, the structural diversity of N-glycans poses analytical challenges that limit the exploration of specific glycosylation functions. In this work, we used THP-1-derived macrophages as examples to show the vast potential of a N-glycan structural interpretation tool StrucGP in N-glycoproteomic analysis. The intact glycopeptides of macrophages were enriched and analyzed using mass spectrometry (MS)-based glycoproteomic approaches, followed by the large-scale mapping of site-specific glycan structures via StrucGP. Results revealed that bisected GlcNAc, core fucosylated, and sialylated glycans (e.g., HexNAc₄Hex₅Fuc₁Neu5Ac₁, N₄H₅F₁S₁) were increased in M1 and M2 macrophages, especially in the latter. The findings indicated that these structures may be closely related to macrophage polarization. In addition, a high level of glycosylated PD-L1 was observed in M1 macrophages, and the LacNAc moiety was detected at Asn-192 and Asn-200 of PD-L1, and Asn-200 contained Lewis epitopes. The precision structural interpretation of site-specific glycans and subsequent intervention of target glycoproteins and related glycosyltransferases are of great value for the development of new diagnostic and therapeutic approaches for different diseases.

OBJECTIVE: To study the correlation of CD44 with epithelial-mesenchymal transition(EMT) and metastasis in nasopharyngeal cancer cells, and explore the possible mechanism of CD44 regulates EMT and metastasis in nasopharyngeal cancer cells. METHOD: The CD44 and EMT-associated proteins in 5-8F and 6-10B nasopharyngeal cancer cell lines were assayed by Western blotting. The erasion trace test was performed to observe the migratory ability of 5-8F and 6-10B nasopharyngeal cancer cells. Using lipid-mediated DNA transfection technique, the low metastatic nasopharyngeal cancer cells 6-10B were transfected in vitro with plasmid which contained CD44 gene, and then new nasopharyngeal cancer cells were obtained. The CD44 and EMT-associated proteins in 6-10B, empty vector transfected and CD44-transfected cells were assayed by Western blotting. The erasion trace test was performed to observe the alteration of migratory ability of nasopharyngeal cancer cells before and after CD44 transfection. RESULT: The expression of CD44 and EMT-associated protein MMP-9 in 5-8F was higher than that in 6-10B, but EMT-associated protein E-Cadherin in 5-8F was lower than that in 6-10B. The migratory ability of 5-8F was higher than that of 6-10B. The expression of CD44 and MMP-9 were significantly higher in the CD44-transfected nasopharyngeal cancer cells than in the control groups. Compared with control groups, the migratory ability of CD44-transfected nasopharyngeal cancer cells was significantly increased. CONCLUSION CD44 positively regulates the metastatic ability of nasopharyngeal cancer cells, which is relevant to the process of EMT.
