OBJECTIVE: To investigate the early clinical efficacy, safety, and application value of one-hole split endoscopy (OSE)-assisted transforaminal lumbar interbody fusion(TLIF) in the treatment of lumbar degenerative diseases. METHODS: A retrospective analysis was conducted on 17 patients with lumbar degenerative diseases who underwent OSE-assisted TLIF between June 2023 and June 2024. There were 10 males and 7 females, with a mean of (55.30±6.52) years old ranging 43 to 65 years. The disease duration ranged from 3 to 36 months with a mean of(12.4±13.3) months. The disease distribution was as follows:lumbar disc herniation (7 cases), lumbar spinal stenosis (5 cases), and lumbar spondylolisthesis (2 cases). Operative time, incision length, intraoperative blood loss, number of intraoperative fluoroscopic exposures, time to ambulation, postoperative hospital stay, and complications were recorded. The dural sac area at the affected segment, visual analogue scale (VAS) for low back pain and leg pain, and Oswestry disability index (ODI) were recorded preoperatively and postoperatively. The modified MacNab criteria were used to evaluate the surgical outcome at the final follow-up. RESULTS: All 17 patients successfully underwent surgery and were followed up for 3 to 15 months with a mean of (8.4±3.3) months. The operative time was 120 to 200 minutes with a mean of (143.2±22.0) minutes, the incision length on the decompression side was 1.80 to 4.00 cm with a mean of (2.56±0.65) cm, intraoperative blood loss was 50 to 300 ml with a mean of (161.2±72.5) ml, the number of fluoroscopic exposures was 15 to 38 with a mean of (23.4±6.5), time to ambulation was 24 to 72 hours with a mean of (49.2±11.9) hours, and postoperative hospital stay was 3 to 9 days with a mean of (4.9±1.5) days. Two patients developed transient lower limb pain and numbness, which completely resolved with conservative treatment. The postoperative dural sac area was (121.47±14.90) mm², which was significantly larger than the preoperative area (51.47±7.69) mm²(P<0.001). The VAS for low back pain were (6.23±1.64), (2.94±1.43), and (1.94±0.75) at preoperation, 3 days postoperation, and final follow-up, respectively;the VAS for leg pain were (7.06±1.43), (2.35±1.17), and (2.06±0.90) at the same time points. The VAS at all postoperative time points were significantly lower than preoperative scores (P<0.001). The ODI at final follow-up was (25.29±8.15)%, which was significantly better than the preoperative ODI of(82.35±5.16)%(P<0.001). At the final follow-up, the MacNab surgical outcome was excellent in 11 cases, good in 4 cases, and fair in 2 cases. CONCLUSION OSE-assisted TLIF is an effective, safe, and minimally invasive technique with a gentle learning curve for the treatment of lumbar degenerative diseases, capable of effectively relieving symptoms and improving function.

PURPOSE: To analyze risk factors for severe trauma and establish a nomogram for early risk prediction, to improve the early identification of severe trauma. METHODS: This study was conducted on the patients treated in 81 trauma treatment institutions in Gansu province from 2020 to 2022. Patients were grouped by year, with 5364 patients from 2020 to 2021 as the training set and 1094 newly admitted patients in 2020 as the external validation set. Based on the injury severity score (ISS), patients in the training set were classified into 2 subgroups of the severe trauma group (n = 478, ISS scores ≥25) and the non-severe trauma group (n = 4886, ISS scores <25). Univariate and binary logistic regression analyses were employed to identify independent risk factors for severe trauma. Subsequently, a predictive model was developed using the R software environment. Furthermore, the model was subjected to internal and external validation via the Hosmer-Lemeshow test and receiver operating characteristic curve analysis. RESULTS: In total, 6458 trauma patients were included in this study. Initially, this study identified several independent risk factors for severe trauma, including multiple traumatic injuries (polytrauma), external hemorrhage, elevated shock index, elevated respiratory rate, decreased peripheral oxygen saturation, and decreased Glasgow coma scale score (all p < 0.05). For internal validation, the area under the receiver operating characteristic curve was 0.914, with the sensitivity and specificity of 88.4% and 87.6%, respectively; while for external validation, the area under the receiver operating characteristic curve was 0.936, with the sensitivity and specificity of 84.6% and 93.7%, respectively. In addition, a good model fitting was observed through the Hosmer-Lemeshow test and calibration curve analysis (p > 0.05). CONCLUSION This study establishes a nomogram for early risk prediction of severe trauma, which is suitable for primary healthcare institutions in underdeveloped western China. It facilitates early triage and quantitative assessment of trauma severity by clinicians prior to clinical interventions.

From the perspective of the physiological basis of liver and kidney sharing the common source in traditional Chinese medicine(TCM),and by integrating the theory of kidney dominating bone,liver dominating tendon,and meridian sinew of TCM as well as the bone resorption and collapse theory,and non-uniform settlement theory and lower-limb musculoskeletal bowstring structure theory of modern orthopedics,the pathogenesis of osteonecrosis of the femoral head(ONFH)under the system of non-uniform settlement during bone resorption and multidimensional composite bowstring working in coordination with the theory of liver-kidney and muscle-bone was explored.The key to the TCM pathogenesis of ONFH lies in the deficiency of the liver and kidney,and then the imbalance of kidney yin-yang leads to the disruption of the dynamic balance of bone formation and bone resorption mediated by osteoblasts-osteoclasts,which manifests as the elevated level of bone metabolism and the enhancement of focal bone resorption in the femoral head,and then leads to the necrosis and collapse of the femoral head.It is considered that the kidney dominates bone,liver dominates tendon,and the tendon and bone together constitute the muscle-bone-joint dynamic and static system of the hip joint.The appearance of collapse destroys the originally balanced muscle-bone-joint system.Moreover,the failure of liver blood in the nourishment of muscles and tendons further exacerbates the imbalance of the soft tissues around the hip joint,accelerates the collapse of the muscle-bone-joint dynamic and static system,speeds up the process of femoral head collapse,and ultimately results in irreversible outcomes.Based on the above pathogenesis,the systematic integrative treatment of ONFH should be based on the TCM holistic concept,focuses on the focal improvement of internal and external blood circulation of the femoral head by various approaches,so as to rebuild the coordination of joint function.Moreover,attention should be paid to the physical constitution of the patients,and therapy of tonifying the kidney and regulating the liver can be used to restore the balance between osteogenesis and osteoblastogenesis,and to reconstruct the muscle-bone-joint system,so as to effectively delay or even prevent the occurrence of ONFH.

Through a compound induction method, combined with neurobehavioral, macroscopic characterization and objective pathological evaluation indicators, a murine depression model of liver depression transforming into fire syndrome was constructed and confirmed. The model was constructed using a combination of sleep deprivation, light exposure, and alternate-day food deprivation. Evaluation was conducted at three levels: face validity, constructs validity, and predictive validity. The establishment of the liver depression transforming into fire syndrome depression model was further validated through the counterproof of traditional Chinese medicine formulas. In terms of face validity, compared to the control group, mice in the model group exhibited typical depressive symptoms in neurobehavioral assessments; the general observation of the model group mice reveals disheveled and lackluster fur, along with delayed and easily agitated responses. Additionally, there is a substantial increase in water consumption. In the sleep phase detection of mouse, the model group showed a significant increase in the proportion of time spent in the wake phase during sleep, accompanied by a significant decrease in the proportions of time spent in both non-rapid eye movement (NREM) and rapid eye movement (REM) sleep phases. There are significant differences in physiological indicators such as average blood flow velocity, blood flow rate, tongue, urine, and claw color (r values) in the internal carotid artery. Structural validity demonstrated that levels of 5-hydroxytryptamine (5-HT), dopamine (DA), and γ-aminobutyric acid (GABA) in the hippocampus of model mice decreased significantly, while acetylcholine (ACh), tryptophan (Try), and glutamic acid (Glu) levels increased significantly. Treatment with Danzhi Xiaoyao San led to varying degrees of restoration in the aforementioned neurotransmitters. In terms of predictive validity, the antidepressant paroxetine effectively ameliorated depressive behaviors in the model mice, and the classic formula Danzhi Xiaoyao San demonstrated varying degrees of improvement in depression-related indicators. In conclusion, this study has established a novel animal model of liver-stagnation with the fire depression, thereby expanding the repertoire of traditional Chinese medicine depression models. This development contributes to the diversification of melancholic syndrome models in Chinese medicine, offering a broader spectrum of options for scientific exploration, efficacy evaluation, and drug screening in the future prevention and treatment of depression with traditional Chinese medicine. Animal experiments were conducted with the approval and supervision of the Animal Ethics Committee of Jiangxi University of Traditional Chinese Medicine (ethics number: 20230313040).

Aim To investigate the synergistic sensiti-zation effect of saikosaponin D(SSD)combined with temozolomide(TMZ)on glioblastoma cells(GBM)and its molecular mechanism.Methods The sensitiv-ity of RG-2,U251 and LN-428 GBM cell lines to SSD and TMZ was analyzed by CCK-8 method combined with HE staining,and the optimal compatible concen-tration was screened.The effect of HE staining com-bined with Hoechst fluorescence staining on the prolif-eration of GBM cell line was detected by clonal forma-tion experiment.The autophagosome formation of GBM cells was observed by monodansylcadaverine(MDC)staining.The expression and distribution of endoplas-mic reticulum stress-related factors and apoptosis and autophagy proteins were detected by Western blot and ICC.Results The sensitivity order of GBM cells to TMZ was RG-2＞U251＞LN-428.The results of com-bined administration showed the synergistic inhibitory effect of SSD combined with TMZ on proliferation of GBM cell lines,which was confirmed by cell cloning formation experiment.Compared with the TMZ group,Hoechst fluorescence staining showed a significant in-crease in the number of nuclear bright staining in the combined administration group.MDC fluorescence staining showed that there were more dense green parti-cles in the cytoplasm of SSD/TMZ plus group than that of TMZ group.Western blot results showed that com-pared with TMZ group,the expression of ER stress markers GRP78,CHOP,p-PERK and ATF6 signifi-cantly increased in SSD/TMZ group(P＜0.05).The expressions of apoptosis proteins caspase-12,caspase-9,caspase-3,cleaved caspase-3,Bax and autophagy proteins LC3 and Beclin-1 significantly increased(P＜0.05),which were verified by ICC test.Conclusions SSD can cooperate with TMZ to inhibit the prolifera-tion of GBM cells and induce apoptosis and autophagy,and enhance the sensitivity of GBM cells to TMZ by ac-tivating endoplasmic reticulum stress pathway.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective:To investigate a new method for the reconstruction of hemifacial microsomia by sagittal osteotomy of the affected mandibular outer cortex combined with bone graft of mandibular outer cortex from healthy side.Methods:From March 2006 to March 2023, the clinical data of patients with hemifacial microsomia admitted to the Department of Craniomaxillofacial Surgery, Plastic Surgery Hospital, Chinese Academy of Medical Sciences were analyzed retrospectively. Preoperative diagnosis and surgical design were performed based on clinical manifestations and imaging findings. All cases were operated under general anesthesia. The affected mandibular outer cortex was previously split by an intraoral approach, and then the mandibular outer cortex of appropriate shape and size on the healthy side was harvested and grafted into the split bone space according to the preoperative design, following by internal rigid fixation. Complications, facial appearance improvement, and patient satisfaction were followed up. Photographs were taken preoperative, immediately postoperative and at the long-term(last) postoperative follow-up, and the severity of the deformity was analyzed. CT data from preoperative, immediate postoperative, and long-term follow-up visits were imported into Surgicase Proplan medical three-dimensional image workstation in Dicom format. The mandible was reconstructed using Segmentation, and the thickness of the mandible was measured during pre-operative, immediate post-operative and long-term follow-up visits. Anova with repeated measurement design was used to compare measurements and LSD test was used for multiple comparisons. The Kruskal-Wallis rank sum test were used to statistically analyze malformation severity. P< 0.05 is considered statistically significant. Results:A total of 39 patients were included in this study, including 13 females and 26 males, with an average age of (22.21±4.57) years (15-27 years). All patients were followed up for an average of (45.56±39.41) months (6-153 months) after surgery. The grafted mandibular outer cortex grows well with the adjacent bone tissue, and the mandibular angle and mandibular body are significantly wider. Of the 39 cases, 1 developed an infection 1 year after surgery, the titanium plate was exposed, and the patient healed after debridement and removal of the immobilizing splint. The facial appearance of the other patients improved significantly. Preoperative, immediate postoperative and long term follow up of mandibular thickness measurements were compared in pairs, and the differences were statistically significant (all P<0.05). The patient’s appearance satisfaction score: the preoperative score was [2.0(1.5, 2.0)] points, the immediate postoperative score was [4.0(4.0, 4.0)] points, the score of the last postoperative follow up was [4.0(4.0, 4.0)] points. There was statistical difference in satisfaction among the three groups ( P<0.01). The preoperative scores were compared with the scores of the immediate postoperative and the last postoperative follow-up respectively, and the differences were statistically significant( P<0.01). There was no statistical significance in satisfaction between the immediate postoperative score and the score of the last postoperative follow up ( P>0.05). Conclusion:The sagittal splitting osteotomy of the mandibular outer cortex is consistent with the features of mandibular anatomy, and provides a good condition for the grafting and healing of autogenous bone. Removing the outer cortex of the mandible on the healthy side not only increases the thickness of the affected side, but also decreases the width of the angle of the mandible on the healthy side, so as to effectively correct the asymmetric deformity of the mandible. The method is simple, with few complications and good results, and is one of the ideal treatments to correct hemofacial microsomia.

Dead heart is an important trait of pith-decayed Scutellariae Radix. The purpose of this study was to clarify the scientific connotation of the dead heart using multi-omics. Metabolomics and transcriptomics combined with multivariate statistical analysis such as principal component analysis(PCA) and partial least squares discriminant analysis(PLS-DA) were used to systematically compare the differences in chemical composition and gene expression among phloem, outer xylem and near-dead xylem of pith-decayed Scutella-riae Radix. The results revealed significant differences in the contents of flavonoid glycosides and aglycones among the three parts. Compared with phloem and outer xylem, near-dead xylem had markedly lowered content of flavonoid glycosides(including baicalin, norwogonin-7-O-β-D-glucuronide, oroxylin A-7-O-β-D-glucuronide, and wogonoside) while markedly increased content of aglycones(including 3,5,7,2',6'-pentahydroxy dihydroflavone, baicalin, wogonin, and oroxylin A). The differentially expressed genes were mainly concentrated in KEGG pathways such as phenylpropanoid metabolism, flavonoid biosynthesis, ABC transporter, and plant MAPK signal transduction pathway. This study systematically elucidated the material basis of the dead heart of pith-decayed Scutellariae Radix with multiple growing years. Specifically, the content of flavonoid aglycones was significantly increased in the near-dead xylem, and the gene expression of metabolic pathways such as flavonoid glycoside hydrolysis, interxylary cork development and programmed apoptosis was significantly up-regulated. This study provided a theoretical basis for guiding the high-quality production of pith-decayed Scutellariae Radix.

The quality evaluation of traditional Chinese medicine is one of the key issues related to the modernization of traditional Chinese medicine. The quality evaluation technology system of traditional Chinese medicine mainly includes traditional evaluation (traits, microscopic and physicochemical identification), chemical evaluation and biological evaluation. Due to the complex composition of traditional Chinese medicine, the single detection method in the above evaluation technology system usually cannot obtain sufficient quality information. The multi-source information fusion strategy can organically integrate data from multiple analysis and detection technologies to obtain more comprehensive information of samples and improve the quality evaluation effect. At present, multi-source information fusion strategy has been widely used in the fields of military, industrial and food, and it is still in its infancy in the field of quality evaluation of traditional Chinese medicine. This research introduces the definition, structure, method (algorithm) and fusion level of multi-source information fusion, summarizes its research progress in the origin traceability, variety identification and pharmaceutical analysis of traditional Chinese medicine, and sorts out the specific methods of data fusion in each literature. Finally, we summarized, prospected and discussed the application, development and existing problems of information fusion technology and its application in the quality evaluation of traditional Chinese medicine, in order to provide reference for broadening the application of this technology in the field of traditional Chinese medicine.
