RESUMO
[Objective]To explore the construction measures of a new pattern of tutor-postgraduate relationship under the background of striving for"double first-class"traditional Chinese medicine(TCM)university,in order to continuously improve the quality of postgraduate training in TCM universities.[Methods]Under the background of striving for"double first-class"TCM universities,this paper introduces the practical significance of building a good mentoring relationship,and analyzes the outstanding problems existing in the mentoring relationship in the current TCM universities from the perspective of tutors and postgraduates-the two main subjects.[Results]Through the establishment of a good mentoring relationship,the tutor-postgraduate relationship has generally been positively influenced,and the communication between teachers and students has become closer and more efficient.Through a series of positive incentive mechanisms,tutors are more active in providing support and help to postgraduates in academic guidance,academic guidance and life care,and postgraduates are more active in cooperating with tutors in various scientific research work.The quantity and quality of academic papers published by postgraduates have been significantly improved,and the scientific research and teaching work of the tutor team have been carried out more efficiently with remarkable progress.[Conclusion]Starting from the three aspects of strengthening the positive core value of"respecting teachers and medicine",perfecting the relevant system and correcting the imbalance of the tutor-postgraduate relationship,the School of Basic Medicine of Zhejiang Chinese Medical University focuses on exploring the new mode of building a good tutor-postgraduate relationship,and puts forward feasible suggestions through a series of measures.This mode has significantly improved the tutor-postgraduate relationship.It not only plays a positive role in improving postgraduates'professional level and communication-scientific research-innovation ability,but also provides a guarantee for tutors to complete teaching and scientific research work successfully,which is worthy of further improvement and promotion.
RESUMO
BACKGROUND:Hyperuricemia is a common metabolic disease,and the main clinical manifestation of patients with hyperuricemia is the formation of uric acid crystals leading to gout.Previous studies have only reported that uric acid crystals lead to intervertebral disc degeneration,but there are fewer studies on the correlation between hyperuricemia and intervertebral disc degeneration. OBJECTIVE:To retrospectively analyze the characteristics of intervertebral disc degeneration in patients with hyperuricemia and the correlation between serum uric acid level and intervertebral disc degeneration. METHODS:A retrospective analysis was performed in all patients diagnosed with intervertebral disc degeneration admitted at the Department of Orthopedics,the Affiliated Hospital of Southwest Medical University from January 2021 to December 2022.There were 97 hyperuricemia patients in the hyperuricemia group and 194 non-hyperuricemia patients in the control group according to sex and age in a ratio of 1:2.Blood uric acid test results were collected,and Pfirrmann scoring was performed for the degree of disc degeneration in patients based on the whole spinal MRI images.The difference in the degree of disc degeneration between the two groups was compared,and the correlation between the serum uric acid level and the degree of intervertebral disc degeneration was analyzed. RESULTS AND CONCLUSION:The Pfirrmann score in the hyperuricemia group was higher than that in the control group,and the total number of disc degeneration in the hyperuricemia group was also significantly higher than that in the control group(P<0.05).Spearman correlation analysis showed that the degree of disc degeneration in male patients was positively correlated with serum uric acid level at many spinal segments in the hyperuricemia group(C3/4:r=0.317,C4/5:r=0.333,C5/6:r=0.309,L2/3:r=0.443,P<0.05);the degree of disc degeneration in female patients was also positively correlated with serum uric acid level(C3/4:r=0.354,C4/5:r=0.388,C6/7:r=0.312,T7/8:r=0.282,T9/10:r=0.305,T11/12:r=0.277,L4/5:r=0.319,L5-S1:r=0.367,P<0.05).In the control group,there was no significant correlation between the degree of disc degeneration and serum uric acid level in male and female patients(P>0.05).To conclude,in patients with hyperuricemia,the higher serum uric acid level indicates the more serious intervertebral disc degeneration.Therefore,hyperuricemia is one of the risk factors for intervertebral disc degeneration.
RESUMO
Objective To analyze the effects of nasal endoscopic continuous penetrating suture and nasal packing on discomfort and complications in patients undergoing deflection of nasal septum(DNS)plasty.Methods 116 patients undergoing DNS plasty were enrolled between March 2018 and March 2023,including 69 cases in packing group score(nasal packing)and 47 cases in suture group(continuous penetrating suture).The scores of pain[evaluated by visual analogue scale(VAS)]and epistaxis caused by nasal dressing changes at 3 and 7 d after surgery,subjective discomfort score(headache,dry mouth,epiphora,sleep difficulties,nasal obstruction and nasal pain)at 3 d after surgery,total inspiratory and expiratory resistance before and at 14 d after surgery,and the occurrence of complications at 1 month after surgery were compared between the two groups.Results At 3 d after surgery,VAS of pain and epistaxis score caused by nasal dressing changes were lower in suture group than packing group(P<0.05),and score of subjective discomfort was lower in suture group(P<0.05).At 14 d after surgery,total inspiratory and expiratory resistance were lower in suture group than packing group(P<0.05).The total incidence of postoperative complications was lower in suture group than packing group(P<0.05).Conclusion Compared with nasal packing,nasal endoscopic continuous penetrating suture can reduce pain and bleeding,improve postoperative subjective discomfort and nasal ventilation function,and reduce complications after DNS plasty.
RESUMO
Objective:To delineate the morphological features of pedicle-facet joints in lumbar spondylolysis patients, correlating these with spinopelvic parameters to explore their mechanisms and clinical implications.Methods:This study enrolled 121 patients with L 5 spondylolysis (IS group), 108 with L 4, 5 degenerative spondylolisthesis (DS group), and 100 with normal L 4, 5 but L 5S 1 lumbar disc herniation (NL group), who underwent radiography and multislice spiral CT from May 2020 to January 2023. Parameters including vertebral slip percentage (SP) and spinopelvic alignments, such as sacral slope and lumbar lordosis, were quantified using standing lateral lumbar radiographs. Morphological parameters of the L 4 and L 5 facet joints were measured on 3D reconstructed lumbar CT images, including the facet joint angle (FJA), pedicle-facet joint angle (PFA), facet joint osteoarthritis (OA), and facet joint tropism (FT). Results:The analysis revealed significant variances in SS and LL among the groups ( F=21.910, P<0.001; F=22.439, P<0.001). The IS group exhibited the highest SS and LL, followed by the DS and NL groups. Morphological assessments showed the largest L 4 FJA in the IS group, with progressive decreases in the DS and NL groups ( F=344.791, P<0.001). Conversely, L 4 PFA was greatest in the DS group ( F=193.725, P<0.001). Notably, L 4 OA was markedly more severe in the DS group compared to IS and NL groups ( H=467.925, P<0.001), with no significant disparity between IS and NL groups ( P>0.05). Correlation analyses within each cohort highlighted a negative association of sacral slope and lumbar lordosis with facet joint angles, yet a positive correlation with pedicle-facet joint angles both with statistical significance ( P<0.05). Furthermore, L 4 facet joint angles were consistently smaller than those at L 5, and L 4 pedicle-facet joint angles were larger than L 5 ( P<0.05). Osteoarthritis at L 5 was more pronounced in the IS group compared to L 4 ( Z=7.043, P<0.001), a trend inversely observed in the DS group ( Z=11.868, P<0.001), while the NL group showed no significant osteoarthritic variance between levels ( Z=0.556, P=0.578). Conclusion:Patients with lumbar spondylolysis demonstrate elevated sacral slope and lumbar lordosis, indicative of increased localized biomechanical stress in the lumbar spine. These alterations in the morphology of the pedicle-facet joints highlight the distinctive structural adaptations and potential strain distributions within this cohort.

RESUMO
BACKGROUND: Hypoxia is a characteristic feature of many solid tumors. As an adaptive response to hypoxia, tumor cells activate hypoxia-inducible factor-1α (HIF-1α). Under hypoxic conditions, angiogenesis mediated by HIF-1α is involved in the growth and metastasis of tumor cells. During the angiogenic process, differentiated tip endothelial cells (ECs) characterized by high expression of DLL4 promote angiogenic germination through filopodia. Inhibitors of HIF-1α or DLL4 have been widely studied PURPOSE: We tried to find inhibitors targeting both HIF-1α and DLL4 in tumor which have not yet been developed. STUDY DESIGN: In this study, we examined a natural compound that inhibits sprouting angiogenesis and tumor growth by targeting both HIF-1α and DLL4 under hypoxic conditions. METHODS: After examining cell viability of 70 selected natural compounds, we assessed the effects of compounds on HIF-1α and DLL4 transcriptional activity using a dual-luciferase reporter assay. Western blot analysis, immunofluoresecnt assay and real-time qPCR were performed to identify expression of proteins, such as HIF-1α and DLL4, as well as HIF-1α target genes under hypoxic conditions. In vitro angiogenesis assay and in vivo allograft tumor experiment were performed to investigate inhibition of tumor growth through anti-angiogenic activity. RESULTS: Among these compounds, steppogenin, which is extracted from the root bark of Morus alba l, respectively inhibited the transcriptional activity of HIF-1α under hypoxic conditions in HEK293T cells and vascular endothelial growth factor (VEGF)-induced DLL4 expression in vascular ECs in a dose-dependent manner. In tumor cells and retinal pigment epithelial cells, steppogenin significantly suppressed HIF-1α protein levels under hypoxic conditions as well as VEGF-induced DLL4 expression in ECs. Furthermore, steppogenin suppressed hypoxia-induced vascular EC proliferation and migration as well as VEGF-induced sprouting of EC spheroids. CONCLUSION: These results suggest that the natural compound steppogenin could potentially be used to treat angiogenic diseases, such as those involving solid tumors, because of its dual inhibition of HIF-1α and DLL4.

Objective:To observe the morphological characteristics of L 4, 5 facet joints in patients with degenerative lumbar spondylolisthesis (DLS) of different spinopelvic types based on Roussouly classification. Methods:We retrospectively analyzed 142 patients with DLS who visited the department of orthopaedics in the Affiliated Hospital of Southwest Medical University from August 2018 to May 2022. There were 33 males aged 65.0±10.7 years and 109 females aged 61.8±9.6 years. The following morphological parameters of the L 4, 5 facet joint were measured on the CT images: facet joint angle (FJA), pedicle facet angle (PFA), facet joint tropism (FT) and facet joint osteoarthritis (OA) degree; the sacral slope (SS), lumbar lordosis (LL) and percentage of L 4 slip distance (SDP) were measured on preoperative standing neutral lumbar radiographs. According to the Roussouly classification, the patients were divided into four groups (type I, type II, type III, and type IV). The differences of morphological parameters of the facet joints and SDP were compared among the four groups, and the correlation between the FJA and PFA was analyzed. Results:There were 142 patients, including 28 type I, 50 type II, 43 type III, and 21 type IV according to the Roussouly classification. The SDPs of type I, type II, type III, and type IV were 19.1%±3.4%, 18.6%±3.9%, 21.7%±3.9%, 25.0%±2.4%, respectively. Except for types I and II, there were statistically significant differences in pairwise comparison among all other types ( P<0.05). The FJAs in type I and type II (31.4°±6.3°, 35.2°±6.8°) were larger than those in type III (28.4°±5.6°) and type IV (23.4°±4.5°), and the FJA in type III was larger than that in type IV. Conversely, the FJA in type I was smaller than that in type II. These differences were statistically significant ( P<0.05). The PFAs in type I and type II (113.9°±4.9°, 111.3°±5.6°) were smaller than those in type III (116.3°±4.4°) and type IV (121.8°±3.5°), and the PFA in type III was smaller than that in type IV, while, the PFA in type I was larger than that in type II. These differences were statistically significant ( P<0.05). The degree of OA in both type I and type II was lower than that in type III and type IV, with statistically significant differences ( P<0.05). However, there were no statistically significant differences in the degree of OA between type I and type II and between type III and type IV ( P> 0.05). Additionally, there were no statistically significant differences ( F=0.40, P=0.752) in the FT values among type I, type II, type III, and type IV (5.8°±2.3°, 5.6°±2.4°, 6.1°±1.8°, 5.9°±1.9°). Pearson correlation analysis showed that FJA was negatively correlated with PFA ( r=-0.68, P<0.001). Conclusion:In the slip segment of DLS, the facet joint morphology was part of the joint configuration in different spinopelvic types, not just the result of joint remodeling after DLS. Morphological characteristics of the facet joints and DLS interacted with each other.

Bibliometric and scientific knowledge graph methods were used to analyze the research status and hot spots of acupuncture-moxibustion in treatment of myofascial pain syndrome (MPS) and explore its development trend. The articles of both Chinese and English versions relevant to MPS treated by acupuncture-moxibustion were searched in CNKI, VIP, Wanfang, SinoMed and WOS from the database inception to March 20, 2023. Using Excel2016, CiteSpace6.2.R2 and VOSviewer1.6.18, the visual analysis was conducted by means of the cooperative network, keyword co-occurrence, keyword timeline, keyword emergence, etc. From Chinese databases and WOS database, 910 Chinese articles and 300 English articles were included, respectively. The annual publication volume showed an overall rising trend. Literature output of English articles was concentrated in Spain, China, and the United States, of which, there was less cross-regional cooperation. In the keyword analysis, regarding acupuncture-moxibustion therapy, Chinese articles focused on "acupuncture", "electroacupuncture" and "acupotomy"; while, "dry needling" and "injection" were dominated for English one. Clinical study was the current hot spot in Chinese databases, in comparison, the randomized controlled double-blind clinical trial was predominant in WOS. Both Chinese and English articles were limited in the report of mechanism research. The cooperation among research teams should be strengthened to conduct comparative research, dose-effect research and effect mechanism research with different methods of acupuncture-moxibustion involved so that the evidences can be provided for deeper exploration.

Hepatocellular carcinoma (HCC) is a common malignant tumor with poor prognosis and high mortality. In this study, we demonstrated a novel vaccine targeting HCC and tumor neovascular endothelial cells by fusing recombinant MHCC97H cells expressing porcine α-1,3-galactose epitopes (αGal) and endorphin extracellular domains (END) with dendritic cells (DCs) from healthy volunteers. END+/Gal+-MHCC97H/DC fusion cells induced cytotoxic T lymphocytes (CTLs) and secretion of interferon-gamma (IFN-γ). CTLs targeted cells expressing αGal and END and tumor angiogenesis. The fused cell vaccine can effectively inhibit tumor growth and prolong the survival time of human hepatoma mice, indicating the high clinical potential of this new cell based vaccine.
RESUMO
OBJECTIVE@#To establish a quantitative evaluation parameter system for basic acupuncture manipulations based on 3D motion tracking technology, and to further analyze the characteristics of acupuncture manipulation.@*METHODS@#The motion tracking system Simi Motion Ver.8.5 was used to collect parameters of acupuncture manipulations, so as to establish a quantitative evaluation system mainly in spatial control parameters, time control parameters and stability parameters. Based on the evaluation parameter system, data of acupuncture manipulations (even reinforcing-reducing manipulation using lifting-thrusting technique and twirling technique) were collected from 19 teachers majored in acupuncture-moxibustion, of which the characteristics were analyzed and were compared with the results tested by traditional ATP-Ⅱ acupuncture manipulation parameter determination apparatus (ATP-Ⅱ).@*RESULTS@#The evaluation parameter system could quantitatively analyze the basic acupuncture manipulations in 3 aspects, i.e. space, time and stability. Acupuncture manipulations were performed by shifting the needle body in a certain range along X, Y and Z axes. The amplitude and speed of thumb movement were greater than those of index finger. The time-history of lifting was similar to thrusting, while the time-history of twirling to left was similar to twirling to right in even reinforcing-reducing manipulation. The coordinate-time curve of finger movement of the evaluation system had consistent wave pattern compared with the voltage-time curve generated by ATP-Ⅱ.@*CONCLUSION@#The quantitative evaluation parameter system based on 3D motion tracking technology can objectively evaluate basic acupuncture manipulations, and show the characteristics of different manipulations and the movement details of finger joints.

OBJECTIVE: To evaluate the efficacy of a novel decellularized porcine bone xenograft, produced by supercritical carbon dioxide extraction technology, on alveolar socket healing after tooth extraction compared to a commercially available deproteinized bovine bone (Bio-Oss®). MATERIALS AND METHODS: Nine dogs (about 18 months old and weighing between 20 kg and 30 kg) underwent extractions of lower second to fourth premolars, bilaterally. The dogs were randomly selected and allocated to the following groups: Group 1: control unfilled socket; Group 2: socket filled with decellularized porcine bone xenograft (ABCcolla®) and covered by a commercially available porcine collagen membrane (Bio-Gide®); Group 3: socket filled with Bio-Oss® and covered by Bio-Gide® membrane. One dogs from each group was sacrificed at 4-, 12-, and 24-week to evaluate the socket healing after tooth extraction. The mandible bone blocks were processed without decalcification and specimens were embedded in methyl methacrylate and subjected to histopathology analyses to evaluate the bone regeneration in the extraction sockets. RESULTS: At 24-week after socket healing, ABCcolla® treated defects demonstrated significantly higher histopathology score in new bone formation and bone bridging, but significantly lower score in fluorescent labeling than those of the Bio-Oss®. In the microphotographic examination, decellularized porcine bone xenograft showed similar characteristics of new bone formation to that of Bio-Oss®. However, there was significantly less remnant implant materials in the decellularized porcine bone xenograft compared to the Bio-Oss® group at 24-week. Thus, the decellularized porcine bone graft seems to have promising bone regeneration properties similar to that of Bio-Oss® with less remnant grafted material in a canine tooth extraction socket model. CONCLUSIONS: Within the limits of the study, we concluded that ABCcolla® treated defects demonstrated significantly more new bone formation and better bone bridging, but less amount of fluorescent labeling than those of the Bio-Oss® group. However, clinical studies in humans are recommended to confirm these findings.

RESUMO
ObjectiveThere is still controversy about which internal fixation method should be used in oblique lateral interbody fusion (OLIF). This paper aims to compare the biomechanical stability of OLIF with different internal fixation methods.MethodsA 31-year-old healthy male volunteer was selected to have a 64-slice spiral CT scan of his lumbar spine. Mimics 19.0, Geomagic Studio 2013, SolidWorks 2017 and other software were used to build a three-dimensional model of L3-L5, and OLIF surgery was simulated to build OLIF finite element models with five different fixation methods: pedicle screw (PS), lateral single rod screw (LSRS), lateral double rod screw (LDRS), lateral single rod screw+ipsilateral translaminar facet screw (LSRS+ITLFS), lateral single rod screw+contralateral translaminar facet screw (LSRS+CTLFS). After validating the validity of the model, the motion modes of spinal flexion, extension, lateral bending and rotation were simulated, and the fixed segment activity and stress distribution characteristics of each model were compared.ResultsIn terms of fixed segment activity, PS had the best fixation effect, and its range of motion (ROM) was the smallest in all 6 modes. The ROM of the vertebral body was maximized when the LSRS was fixed in all directions. LSRS+ITLFS, LSRS+CTLFS and PS had the similar ROM. In terms of maximum stress of cage, PS had the minimum one except in the left bending. LSRS+ITLFS had little stress in all directions except in flexion; LSRS+CTLFS had little stress in all directions except in extension. In terms of the maximum stress in internal fixation, PS had the least one in all directions; LSRS+CTLFS followed, and the maximum stress appeared in extension and right bending (123.05MPA and 91.74MPA, respectively).ConclusionIn OLIF surgery, PS has the best biomechanical effect. LSRS+CTLFS has the similar effect and its clinical operation is simple with relatively small surgical injury, thus providing a reference for clinical choice.
