Objective:To compare the application of cloning sequencing and third-generation nanopore sequencing technology in the identification of raw materials mixed in Tibetan patent medicine Shiliujianwei powder,and to pro-vide a reference for the establishment of the specific identification method for the formulation of medicinal prepara-tions using the raw powder of medicinal herbs or herbal pieces.Methods:By investigating the different concentra-tions of ExTaq enzyme,genomic DNA,upstream and downstream primers in the PCR amplification system,the suit-able PCR amplification system of genomic DNA universal primers for self-made Tibetan medicine Shiliujianwei powder was determined.The amplified products of Shiliujianwei powder were sequenced by two methods,the first was cloned and sequenced by Sanger sequencing technology,and the second was sequenced by third generation nanopore sequen-cing technology.Results:The addition of ExTaq enzyme,upstream and downstream primers and genomic DNA in 20 μL PCR amplification system of Shiliujianwei powder and single medicinal samples were determined to be 0.4,1.5 and 1 μL,respectively.The amplification products of the DNA from self-made Shiliujianwei powder were cloned and sequenced by Sanger sequencing technology,then only the ITS2 sequence of Carthami flos was obtained.The amplified products of self-made pomegranate Jianwei powder DNA were sequenced by three-generation nanopore se-quencing technology,and the ITS2 sequences of Granati semen,Carthami flos,Piperis longi fructus and Amomi fruc-tus rotundus were finally obtained,but the ITS2 sequence of cinnamomi cortex was not obtained.Conclusion:Both cloning sequencing and the third generation nanopore sequencing could solve the problem of overlapping peaks in the direct sanger sequencing for the universal primer amplification products of patent drugs.The third generation nano-pore sequencing was better than cloning sequencing in the sequencing of the universal primer amplification products of patent drugs,but there were still one raw material medicine that have not been detected.It is of certain reference val-ue for the molecular biological identification and DNA barcoding study of different raw materials in the patent medi-cine to establish the specific identification method of Tibetan patent medicine Shiliujianwei powder.

Vertebral refracture following percutaneous vertebral augmentation (PVA) is commonly seen in elderly patients with osteoporotic thoracolumbar compression fractures (OTLCF). It can lead to recurrent pain, loss of vertebral height, progression of kyphosis, and even neurological dysfunction, significantly impairing patients′ quality of life. Current diagnosis and treatment face multiple challenges, including high misdiagnosis rate, difficulty in choosing between surgical and non-surgical treatment options, lack of standardized surgical protocols, interference from intralesional bone cement during procedures, inadequate stability of internal fixation in osteoporotic bone, and suboptimal compliance of anti-osteoporotic therapy. Establishing a standardized diagnostic and therapeutic framework is urgently needed. To standardize the management process and improve outcomes for vertebral refractures after PVA in elderly OTLCF patients, Spinal Trauma Group of the Orthopedic Branch of Chinese Medical Doctor Association organized experts in the field to develop Guideline for the diagnosis and treatment of vertebral refracture after percutaneous vertebral augmentation in elderly patients with osteoporotic thoracolumbar compression fractures ( version 2025), based on current literature and clinical experience, and adhering to principles of scientific rigor and clinical applicability. A total of 11 recommendations were proposed, encompassing diagnosis, treatment, and rehabilitation of vertebral refracture after PVA in elderly patients with OTLCF, aiming to provide a foundation for a standardized management.

Thoracolumbar spine fracture often leads to severe pain, functional impairments, and neurological deficits, for which open reduction and internal fixation can effectively restore the spinal structural stability. Open decompression and reduction with internal fixation can help relieve spinal cord compression and improve spinal function in cases of concomitant cord injury. Although spinal stability can be restored through surgery, patients often face chronic pain and functional impairments postoperatively. A postoperative rehabilitation program is critical in optimizing therapeutic outcomes, reducing complications, and minimizing the risk of secondary injuries. However, current rehabilitation methods, such as physical therapy, functional training, and pain management, are confronted with problems in clinical practice, including significant variation in efficacy, poor patient adherence, and prolonged rehabilitation period. There is an urgent need for a unified rehabilitation strategy to address these problems. To this end, the Spinal Trauma Group of the Orthopedic Physicians Branch of the Chinese Medical Association and the Spine Health Professional Committee of the Chinese Human Health Technology Promotion Association organized experts from relevant fields to formulate Evidence-based guidelines for rehabilitation treatment after internal fixation of thoracolumbar spine fracture in adults ( version 2025) by integrating evidences from clinical researches and advanced rehabilitation concepts at home and abroad. A total number of 14 recommendations concerning the rehabilitation treatment with multimodal analgesia, psychological intervention, deep vein thrombosis prevention, core muscle and extremity exercise, appropriate use of braces, early weight-bearing, device-aided rehabilitation exercise, neuroregulatory therapy, rehabilitation team were put forward, aiming to standardize the post-operative rehabilitation process following internal fixation, promote the functional recovery, and enhance patients′ quality of life.

Acute symptomatic osteoporotic thoracolumbar compression fracture (ASOTLF) can lead to chronic low back pain, kyphosis deformity, pulmonary dysfunction, loss of mobility, and even life-threatening complications. Vertebral augmentation is currently the mainstream treatment method for this condition. In 2019, the Editorial Board of Chinese Journal of Trauma and the Spinal Trauma Group of Orthopedic Surgeons Branch of Chinese Medical Doctor Association collaboratively led the development of Clinical guideline for vertebral augmentation for acute symptomatic osteoporotic thoracolumbar compression fractures. Six years later, with advances in clinical diagnosis and treatment techniques as well as accumulating evidence in related fields, the 2019 guideline requires updating. To this end, the Spinal Trauma Group of Orthopedic Surgeons Branch of Chinese Medical Doctor Association, the Spinal Health Professional Committee of China Human Health Science and Technology Promotion Association, and the Minimally Invasive Orthopedics Professional Committee of Shaanxi Medical Doctor Association have organized experts in the field to develop the Clinical guideline for vertebral augmentation of acute symptomatic osteoporotic thoracolumbar compression fractures ( version 2025) , based on the latest evidence-based medical researches. This guideline incorporates 3 recommendations retained from the 2019 version with updated strength of evidence, along with 12 new recommendations. It provides recommendations from six aspects of diagnosis, pain management, treatment option selection, prevention of postoperative complications, anti-osteoporosis therapy, and postoperative rehabilitation, aiming to provide a reference for standard treatment of vertebral augmentation for ASOTLF in hospitals at all levels.

Schizophrenia is a prevalent mental-behavioral disorder characterized by perceptual disturbances,affective dysregulation,and behavioral abnormalities.In traditional Chinese medicine,it is classified under"manic depressive psychosis"according to its symptomatology.The concepts of"spirit,soul,and inferior spirit"originate from Lingshu·Benshen.Drawing on the concept of"spirit governs the soul and inferior spirit"from Lei Jing,this study explored schizophrenia pathogenesis and treatment from the perspective of the three-level regulation of spirit,soul,and inferior spirit.The core pathogenesis involves failure of spirit to govern as the root cause,disruption of soul homing as the pathodynamic process,and the loss of inferior spirit's somatic functional expression as the manifestation.The pathological locations are the heart,liver,and lungs.Therapeutic strategies are developed according to the pathological transmission pattern"spirit derangement,soul floating,inferior spirit dissipation,"forming a treatment system that emphasizes"calming the heart and tranquillization,restoring its control to solidify the root;suppressing the liver soul and regulating the central mechanism to pacify excess to stop mania;purifying the lungs and calming the inferior spirit to restore its clarity and regulate sensory perception and restore cognition."The treatment emphasizes the synergistic use of"calming the spirit,stabilizing the soul,and soothing the inferior spirit,"and combines acupuncture and repetitive transcranial magnetic stimulation and other treatments to treat both the manifestation and root cause of schizophrenia.Exploring the syndrome differentiation and treatment of schizophrenia from the perspective of spirit,soul,and inferior spirit,aiming to provide a theoretical basis for the treatment of schizophrenia with traditional Chinese medicine.

Aim To elucidate the underlying mecha-nism by which total triterpenoids extracted from Hove-nia dulcis(H-TP)enhance the sensitivity of A549/DDP cells to cisplatin.Methods The ARE-Nrf2 lu-ciferase reporter assay was applied to investigate the impact of H-TP on Nrf2 expression.Western blot was used to detect the protein levels of Keap-1/Nrf2/HO-1,Nrf2-GPX4 signaling pathway,apoptosis-related proteins of Bcl-2 and Bax.Further validation of its effects on Nrf2 was conducted by using Nrf2 activator/inhibitor.Results H-TP could enhance the sensitivi-ty of A549/DDP cells to cisplatin by modulating the expression of apoptosis-related proteins Bax and Bcl-2,inhibiting the Keap-1/Nrf2/HO-1/GPX4 signating pathway in A549/DDP cells,and inducing ferroptosis.Conclusion H-TP enhances the sensitivity of A549/DDP cells to cisplatin by inducing the Nrf2-mediated ferroptosis pathway.

Objective:To investigate the clinical characteristics and prognosis of patients with locally advanced or metastatic pulmonary neuroendocrine tumors(NETs).Methods:The clinical records of patients with locally advanced or metastatic pulmonary NETs in Peking Uni-versity Cancer Hospital&Institute were selected from January 2014 to June 2024.The clinical characteristics,treatment,and survival pro-gnosis were then analyzed.Results:There were 32 patients,of which 18 were male and 14 female.The median age was 56 years.Nine pa-tients had typical carcinoid and 23 had atypical carcinoid,with six in stage Ⅲ and 26 in stage Ⅳ.The common metastatic sites included the bones(18 cases),lungs(8 cases),pleura(7 cases),and liver(7 cases).The median length of the measurable primary tumor was 5.2 cm,which was mostly located centrally(22 cases).Five among the 16 patients who underwent somatostatin receptor(SSTR)imaging had high SSTR ex-pression.The initial symptoms mainly included respiratory symptoms,and none of them were combined with carcinoid syndrome.For the first-line treatment,19 patients were treated with chemotherapy,seven were treated with targeted therapy,four were treated with soma-tostatin analogs(SSAs),and two were treated with surgery.The best efficacy was evaluated as a partial response in one case(3.1%),stable disease in 23 cases(71.9%),and non-evaluable or unknown in eight cases(25%)in the first-line treatment.The median progression-free sur-vival(mPFS)of patients who received first-line treatment was 5.2 months(95%CI:0.0-13.9).The PFS of targeted therapy was the longest(11.0 months,95%CI:0.0-29.6),but there was no significant difference compared with the PFS of chemotherapy and SSA groups(P>0.05).The longest PFS(24.5 months,95%CI:0.0-58.7)was found in patients treated with chemotherapy combined with radiotherapy,but there was no significant difference compared to the PFS of the combined immunotherapy and combined anti-angiogenesis groups(P>0.05).The survival rates at 1,3,and 5 years were 79.1%,65.5%,and 58.9%,respectively.Cox regression analysis did not identify independent risk factors for prognosis.Conclusions:The initial symptoms of patients with locally advanced or metastatic NETs were mainly respiratory symp-toms but without specific manifestations.Some of them were accompanied by high SSTR expression,and there was generally no carcinoid syndrome.The first-line systemic therapy mainly included chemotherapy and target therapy,with relatively low objective response and high disease control rates.Targeted therapy and combined radiotherapy have longer PFS than that of chemotherapy.The overall survival of pa-tients with pulmonary NETs was good.

Aim To investigate the protective effects of Tilianin on lipopolysaccharide(LPS)-induced septice-mia-induced myocardial injury in rats and to explore the related mechanisms.Methods Animals were ran-domly grouped and a rat septicemia-induced myocardial injury model was constructed.Echocardiography was used to assess the cardiac function of rats,left ventricu-lar internal diameter at end-diastole(LVIDd)and left ventricular internal diameter at end-systole(LVIDs)were measured,and left ventricular ejection fraction(LVEF)and left ventricular fractional shortening(LVFS)were calculated;the kits were used to detect the serum activity of the relevant cardiac enzymes and the level of inflammatory factors;HE staining was used to observe the morphological changes of myocardium;immunofluorescence staining of cardiac tissues was used to detect the nuclear translocation of NF-κB p65;Western blot was used to detect the expression of TLR4,MyD88,p-NF-κB p65,and NLRP3 proteins in cardiac tissues.Results Compared with the model group,each administration group differently upregulated LVEF,LVFS,and LVIDs,and improved the coordina-tion of LV wall fluctuations in the model group of rats;cardiac enzymes LDH and CK-MB levels increased,and levels of inflammatory factors TNF-α,IL-6,and IL-1 β were reduced,exerting cardioprotective effects;HE staining showed that myocardial tissue cell gap was re-duced,myocardial fiber breakage was reduced,cardio-myocyte arrangement tended to be normal,and inflam-matory cell infiltration was reduced;NF-κB p65 entry into the nucleus was reduced,and phosphorylated NF-κB p65(p-NF-κB p65)expression was reduced;and Western blot results showed that the expression of TLR4,MyD88,and NLRP3 proteins was reduced.Conclusions Tilianin pretreatment reduces serum my-ocardial enzymes and inflammatory factors and im-proves myocardial injury in rats with septicemia-in-duced myocardial injury,which may be related to the Tilianin anti-TLR4/NF-κB/NLRP3 inflammatory signa-ling pathway.

Objective:To investigate the influencing factors of pathological positive surgical margins(PSM)after radical resec-tion of prostate cancer.Methods:The clinical data of 407 patients who underwent radical resection of prostate cancer in our hospital from 2011 to 2020 were retrospectively analyzed.And the patients were divided into two groups according to postoperative pathological results.Single factor analysis was used to evaluate the differences in postoperative Gleason score,preoperative total prostate-specific antigen(tPSA),preoperative serum free prostate-specific antigen to preoperative tPSA ratio(fPSA/tPSA),clinical stage,postopera-tive pathological stage,operation method,age,body mass index(BMI),diameter and volume of prostate tumor.Multivariate logistic regression was used to determine the independent risk factor of PSM.Results:Among 407 patients with prostate cancer,179 cases(43.98％)were positive.Univariate analysis showed that there were significant differences in postoperative Gleason score,preopera-tive tPSA,clinical stage and postoperative pathological stage between the two groups(P＜0.05).And Gleason score,preoperative tPSA and pathologic stage were independent risk factors for PSM.Conclusion:There are relationships between PSM and post opera-tive Gleason score,tPSA,clinical T stage,postoperative pathologic pT stage.Among them,postoperative Gleason score(Gleason=7 points,Gleason≥8 points),preoperative total prostate-specific antigen(tPSA＞20 μg/L),and postoperative pathologic pT stage(pT3a,pT3b)were independent risk factors for positive pathological margins of prostate cancer.

Objective:To evaluate the therapeutic efficacy of an upper limb rehabilitation robot on the recovery of elbow function recovery following arthroscopic elbow joint release.Methods:Seventy-two patients who underwent arthroscopic elbow joint release at Shanghai Sixth People’s Hospital from December 2022 to December 2023 were recruited. All patients were randomly assigned to either the conventional group (n=36; 16 males, 20 females; age 34.39±9.04 years, range 24-56; fractures: 4 intercondylar humerus, 18 olecranon, 8 radial head, 6 other) which received conventional rehabilitation postoperatively, or the robot-assisted group (n=36; 18 males, 18 females; age 33.78±9.98 years, range 20-59; fractures distribution identical to the conventional group) receiving conventional rehabilitation combined with robot-assisted upper limb rehabilitation therapy. The active range of motion (ROM) of elbow joint, Mayo elbow performance score (MEPS), visual analogue scale (VAS) of elbow joint were recorded preoperatively and at 4 weeks and 3 months postoperatively. The surface electromyography were analyzed at 3 months postoperatively.Results:All patients completed the 3-month rehabilitation program. At 4 weeks postoperatively, the conventional group exhibited a mean active ROM of 106.78°±9.91°, MEPS of 67.78±7.68, VAS of 2.11±0.74; the robot-assisted group showed active ROM of 113.72°±7.06°, MEPS of 73.33±9.28, VAS of 21.89±0.46. By 3 months postoperatively, the conventional group achieved a mean active ROM of 118.11°±6.75°, MEPS of 85.00±8.66, VAS of 0.67±0.67; robot-assisted achieved a mean active ROM of 127.61°±6.61°, MEPS of 91.11±6.57, VAS of 0.39±0.49. Both groups exhibited significant improvements in active ROM and MEPS, and significant reductions in VAS scores at 4 weeks and 3 months postoperatively compared with preoperatively values ( P<0.05). The robot-assisted group demonstrated significantly higher active ROM and MEPS at both 4 weeks and 3 months postoperatively, and a significantly lower VAS score at 3 months postoperatively, compared with the conventional group ( P<0.05). Surface electromyography at 3 months revealed significantly higher biceps brachii root mean square and significantly lower co-contraction index in the robot-assisted group compared to the conventional group ( P<0.05). No adverse symptoms were reported in the treated elbows of either group during the operation and follow-up period. Conclusion:The integration of upper limb rehabilitation robot-assisted therapy and conventional rehabilitation program significantly enhances the recovery of elbow range of motion and functional outcomes at 3 months following arthroscopic elbow joint release.
