BACKGROUND:One-hole split endoscope as a new type of endoscopic technique is suitable for the treatment of far lateral lumbar disc disease.However,there are few research data on L5/S1,which has a very low incidence of far lateral lumbar disc herniation at home and abroad,and there is no detailed image anatomical data describing the one-hole split endoscope treatment of L5/S1 far lateral lumbar disc herniation. OBJECTIVE:Through the three-dimensional image reconstruction,the bony landmarks were determined to accurately locate the positional relationship between the L5 outlet nerve root,the L5/S1 intervertebral space and other structures.One-hole split endoscope via posterolateral approach was used to accurately,safely and effectively decompress the L5 outlet nerve root and treat the L5/S1 far lateral lumbar disc herniation. METHODS:Twenty-nine patients with L5/S1 unilateral far lateral lumbar disc herniation who met the inclusion and exclusion criteria were selected,including 12 males and 17 females at the age of 48-74 years.The lumbar CT data of the patients were imported into Mimics 21.0 software to reconstruct the three-dimensional lumbar model.Measurement of L5/S1 related parameters:(1)Measurement on the sagittal plane at the intersection(H)of the lower edge of the transverse process and the lateral edge of the isthmus:The vertical distance between H and the upper and lower edges of L5 outlet nerve root(a1,a2);the vertical distance between H and the lower endplate of L5 and the upper endplate of S1(b1,b2);vertical distance from the lower edge of the pedicle from H to L5(c).(2)Horizontal distance between the left and right sides of the sagittal surface where the medial wall of the pedicle was located from H to L5(d).(3)The horizontal distance from H to the left and right side of the sagittal plane where the lateral margin of the dura was located(e).(4)Horizontal distance(f)between the left and right sides of the sagittal plane at the outermost edge of the lower endplate from H to L5.(5)Measurements were made on the sagittal plane where the outermost edge of the lower endplate of L5:The vertical distance between the cross section of H and the upper and lower edges of L5 outlet nerve root(g1,g2);vertical distance(h1,h2)between the transverse section of H and the lower endplate of L5 and the upper endplate of S1,respectively;(6)anteroposterior horizontal distance from H to L5 in the coronal plane where the last edge of the nerve root exits(i);(7)anteroposterior horizontal distance from the highest point of the posterior margin of the sacral wing to the last margin of the inferior endplate of L5 in the coronal plane(j). RESULTS AND CONCLUSION:(1)There was no significant difference in the relevant measurement parameters between men and women(P>0.05).(2)a1,a2,b1,b2,c,d,e,f,h1,h2,g1,g2,i,and j on the affected side were not significantly different from the healthy side(P>0.05).(3)There was no significant difference between a1 and c(P>0.05),indicating that the lower edge of the pedicle was the upper edge of the L5 outlet nerve root;the L5 outlet nerve root was close to the lower edge of the pedicle and ran anterolateral behind the L5 vertebral body,and H was located above the L5 outlet nerve root.(4)With H as the bony marker point,it was not necessary to probe upward or to remove the isthmus,but only to grind part of the bone downward and laterally to reveal the L5 outlet nerve root and vertebral space,and to have enough safe distance to avoid damage to the dural membrane to complete exploration and decompression of the lateral recess and foraminal region.(5)The surgeon could operate in the sagittal plane where the most lateral edge of the L5 inferior endplate was located,and in the"rectangular area"formed by the L5 transverse process and the sacral wing.The closer to the medial and inferior area(Kambin triangle),the safer the operation was.(6)It is suggested that using H as the bony landmark point to locate the L5 outlet nerve root and intervertebral space through one-hole split endoscope via posterolateral approach can achieve accurate,safe and effective decompression of L5/S1 far lateral lumbar disc herniation.

Drug repurposing offers a promising alternative to traditional drug development and significantly reduces costs and timelines by identifying new therapeutic uses for existing drugs. However, the current approaches often rely on limited data sources and simplistic hypotheses, which restrict their ability to capture the multi-faceted nature of biological systems. This study introduces adaptive multi-view learning (AMVL), a novel methodology that integrates chemical-induced transcriptional profiles (CTPs), knowledge graph (KG) embeddings, and large language model (LLM) representations, to enhance drug repurposing predictions. AMVL incorporates an innovative similarity matrix expansion strategy and leverages multi-view learning (MVL), matrix factorization, and ensemble optimization techniques to integrate heterogeneous multi-source data. Comprehensive evaluations on benchmark datasets (Fdataset, Cdataset, and Ydataset) and the large-scale iDrug dataset demonstrate that AMVL outperforms state-of-the-art (SOTA) methods, achieving superior accuracy in predicting drug-disease associations across multiple metrics. Literature-based validation further confirmed the model's predictive capabilities, with seven out of the top ten predictions corroborated by post-2011 evidence. To promote transparency and reproducibility, all data and codes used in this study were open-sourced, providing resources for processing CTPs, KG, and LLM-based similarity calculations, along with the complete AMVL algorithm and benchmarking procedures. By unifying diverse data modalities, AMVL offers a robust and scalable solution for accelerating drug discovery, fostering advancements in translational medicine and integrating multi-omics data. We aim to inspire further innovations in multi-source data integration and support the development of more precise and efficient strategies for advancing drug discovery and translational medicine.

BACKGROUND:One-hole split endoscope technique has been widely used in the treatment of lumbar degenerative diseases,but there is no relevant literature on the safety analysis of this technique in the treatment of upper lumbar disc herniation. OBJECTIVE:To observe the position relationship of nerve roots,intervertebral space and bone landmarks in the upper lumbar spine by three-dimensional lumbar CT reconstruction technology,and to provide a basis for the clinical operation of one-hole split endoscope surgery. METHODS:Twenty-six patients with upper lumbar disc herniation underwent a lumbar CT scan.Mimics 17.0 software was imported to measure the related imaging parameters of L1/2 to L3/4 segments:(1)Measurement of vertical distance:In coronal view,the distance(a)from the intersection point of the medial facet of the superior articular process and the superior endplate(N)to the apex of the articular process(S);in the coronal view,the distance(b)from the sagittal intersection(M)of N and the inferior endplate to the apex of the inferior articular process(X).(2)Measured horizontal distance:the distance(c)between the cross-section of N and the lower edge of the outlet nerve root(N2);distance(d)between the cross-section of N and the intersection point of neural tissue(N1);N1 to N2 distance(e);distance(f)between the cross-section of M and the lateral edge of the nerve tissue(M1);M to M cross-section and exit nerve root intersection(M2)distance(g);distance(h)from M1 to M2;distance(i)from M2 to N1;distance(j)from the posterior edge of the articular surface(R)to M2 in sagittal view of the superior articular process. RESULTS AND CONCLUSION:(1)With the decrease of the segment,the distances a and b gradually increased,and the distance j gradually decreased.There was no significant difference between L1/2 and L2/3 segments(P>0.05).(2)With the decrease of the segment,distance d first decreased and then increased;distance f gradually decreased;distances c,e,g,h and i gradually increased;and there was no significant difference between L2/3 and L3/4 segments(P>0.05).(3)Distance i was the shortest distance without pulling nerve roots in the natural state,and the area of the safety zone was between four points M1,M2,N1,and N2.The bone was removed to the upper and lower endplates by biting the bone downward and upward through S and X,respectively,to expose the intervertebral space,and the window of distance g to M2 could be opened outward to avoid injury of the outlet nerve roots.(4)In conclusion,the upper lumbar vertebrae have unique anatomical characteristics.Based on the relevant measurements of nerve roots,spinal dura and intervertebral space,the parameters of the one-hole split endoscope technique are more accurate and safe during operation.

Objective To investigate the surgical method and clinical outcome using the free anterolateral thigh flap with the medial gastrocnemius artery as the recipient artery for the repair of complex wounds in the lower leg. Methods A retrospective analysis was conducted on the clinical data of 11 patients with complex wounds in the lower leg admitted to Suzhou Ruihua Orthopedic Hospital from October 2020 to September 2022. All patients had extensive skin and subcutaneous soft tissue defects in the lower leg and received free anterolateral thigh flap repair with the medial gastrocnemius artery as the recipient artery. The skin of donor site was directly sutured. Results All 11 free skin flap survived in 11 patients, and both the donor and recipient sites healed in stage I. All patients were followed up after discharge, with a follow-up time of 12 to 35 months. The follow-up results at 12 months postoperatively showed good wound healing, good flap appearance and elasticity, restoration of normal knee and ankle joint function, and independent living ability. The donor site wounds healed well without significant scar hyperplasia. At the last follow-up, the flap sensory function was graded as S3 in 2 patients and S2 in 9 patients. The functional score of the affected limb was excellent in 5 patients and good in 6 patients, with an excellent and good rate of 100%. Conclusion The medial gastrocnemius artery has a suitable vessel caliber for anastomosis and a constant location. The use of the free anterolateral thigh flap with this artery as the recipient artery for the repair of severe wounds in the lower leg can effectively cover soft tissue defects and avoid injuring the residual main vessels in the lower leg, resulting in satisfactory outcomes.

In this study, 34 deep eutectic solvents (DESs) were successfully prepared for the extraction of proanthocyanidin from Rhodiolae Crenulatae Radix et Rhizomes. The extraction process was optimized using single factor exploration and Box-Behnken design-response surface analysis. The extraction rate was significantly improved when the molar ratio of choline chloride to 1,3-propanediol was 1:3.5 and the water content was 30% (V/V) in DESs. AB-8 macroporous resin and ethyl acetate were used for separation and refining, and the oligomer-rich proanthocyanidin components were eventually obtained. The ultraviolet (UV) and infrared (IR) spectra showed that the proanthocyanidins were mainly composed of catechin and epicatechin. To further clarify the chemical composition of proanthocyanidin, an ion scan list containing 156 proanthocyanidins precursors was obtained by constructing a proanthocyanidins structural library and mass defect filtering (MDF) algorithm, combined with the full mass spectrometry (MS)/dd-MS2 scan mode that turns on the "if idle pick others" function. By using ultra-high performance liquid chromatography and high-resolution MS (UHPLC/HRMS), the analysis used both targeted and non-targeted methods to detect proanthocyanidins. Finally, 50 oligomeric proanthocyanidin (OPC) compounds were identified, including 7 monomers, 22 dimers, 20 trimers, and 1 tetramer, most of which were procyanidins of proanthocyanidins (84%), and a small amount of prodelphinidin (14%) and other types of proanthocyanidins (2%), which enabled the systematic characterization of proanthocyanidin components from Rhodiolae Crenulatae Radix et Rhizomes. Meanwhile, the comparison with the grape seeds OPCs standard (United States Pharmacopeia) revealed that the proanthocyanidins in Rhodiolae Crenulatae Radix et Rhizomes were more abundant, suggesting that the proanthocyanidins in Rhodiolae Crenulatae Radix et Rhizomes has promising applications.

Plant-derived nanovesicles have gained attention given their similarity to mammalian exosomes and advantages such as low cost, sustainability, and tissue targeting. Thus, they hold promise for disease treatment and drug delivery. In this study, we proposed a time-efficient method, PEG 8000 combined with sucrose density gradient centrifugation to prepare ginger-derived nanovesicles (GDNVs). Subsequently, curcumin (CUR) was loaded onto GDNV by ultrasonic incubation. The optimum conditions for ginger-derived nanovesicles loaded with curcumin (CG) were ultrasound time of 3 min, a carrier-to-drug ratio (GDNV:CUR) of 1:1. The study achieved a high loading capacity (94.027% ± 0.094%) and encapsulation efficiency (89.300% ± 0.344%). Finally, the drugs' in vivo distribution and anti-colitis activity were investigated in mice. CG was primarily distributed in the colon after oral administration. Compared to CUR and GDNV, CG was superior in improving disease activity, colon length, liver and spleen coefficients, myeloperoxidase activity, and biochemical factor levels in ulcerative colitis (UC) mice. In addition, CG plays a protective role against UC by modulating serum metabolite levels and gut flora. In summary, our study demonstrated that GDNV can be used for CUR delivery with enhanced therapeutic potential.
