BACKGROUND:How to repair bone defect has been a clinical problem for a long time.The effective ingredients of traditional Chinese medicine have good biological activity and therapeutic effect,and the combination of effective ingredients of traditional Chinese medicine and tissue engineering materials has a broad prospect in the field of bone repair.The combination of different effective ingredients of traditional Chinese medicine and scaffolds has similarities in their functional relationships. OBJECTIVE:To collect the cases of the combinations of effective ingredients of traditional Chinese medicine and scaffolds,then analogize tissue engineering scaffolds and effective ingredients of traditional Chinese medicine into two types of traditional Chinese medicine that generate compatibility relationships based on the inspiration of the compatibility of seven emotions and summarize the relationship between the two based on their functional relationships. METHODS:Relevant articles from January 1998 to January 2024 were searched in PubMed and China National Knowledge Infrastructure(CNKI),using English search terms"traditional Chinese medicine,Chinese medicine,traditional Chinese medicine monomers,bone defect,bone repair,bone tissue engineering,tissue engineering,scaffold"and Chinese search terms"traditional Chinese medicine,effective ingredients of traditional Chinese medicine,traditional Chinese medicine monomers,bone tissue engineering,bone tissue engineering scaffold,scaffold,tissue engineering,bone defect,bone repair."A total of 88 articles were included for review and analysis. RESULTS AND CONCLUSION:(1)Both tissue engineering scaffold materials and active ingredients of traditional Chinese medicine have been widely used in the field of bone repair.Although they have obvious advantages in osteogenesis,there are still many shortcomings.Many studies are dedicated to preparing composite materials from the two,hoping to exert a detoxification and synergism through the interaction between the two.(2)Some drugs and materials can promote each other in osteogenesis,antibacterial,and promoting angiogenesis,enhancing their original effects.Inspired by the traditional concept of prescription compatibility,this article summarized it as a"Mutual promotion"relationship and provided examples to support it.(3)Some drugs can enhance the strength of materials,while some materials can achieve sustained release and controlled release effects,increase drug loading and stability,or achieve targeted delivery of drugs loaded on them.The article summarized this unilateral enhancement effect as a"Mutual assistance"relationship.(4)The combination of some traditional Chinese medicine and materials can reduce the toxic side effects of the other party.The article summarizes this detoxification relationship as"Mutual restraint and detoxification."(5)The article provided a new perspective on traditional Chinese medicine composite scaffolds,inspired by the seven emotions compatibility relationship and based on the classification of action relationships.It introduced traditional Chinese medicine concepts into the field of tissue engineering,providing new research ideas for subsequent researchers of composite scaffolds,and providing certain convenience in material selection and matching.

Objective To explore the influence of processing depth of verb comprehension on the pro-cess of sensorimotor simulation of verbs and its automatization characteristics.Methods Thirty-six com-mon college students were selected,and required to complete verb semantic judgment tasks of Experi-ment 1 and non-semantic judgment tasks of Experiment 2.The changes in hand and foot action out-puts were also observed.Results In Experiment 1,in semantic judgment tasks,the reaction time of leg-related verbs was significantly shorter than for hand-related verbs(P=0.001),with no significant differences in true-false word judgment tasks.Moreover,in Experiment 2,no significant interaction ef-fect was found between verb types and action execution(P=0.199).Conclusion The sensorimotor simula-tion triggered by verb comprehension is modulated by processing of different depths,and individuals are more inclined to utilize sensorimotor simulation of verbs at higher levels of processing depth,non-automatically.

Objective To explore the effects of the long non-coding RNA(lncRNA)NK2 homeobox 1-antisense RNA 1(NK2-1-AS1),which mediates the microRNA(miR)-96-5p/PR domain-containing protein 16(PRDM16)axis,on anaplastic thyroid cancer(ATC)cell proliferation,migration,and invasion in vitro and transplanted tumor growth in vivo.Methods The differentially expressed lncRNA NKX2-1-AS1 in ATC tissues and cells,its target miRNA miR-96-5p,and its downstream target gene PRDM16 were screened using a bioinformatics analysis.The dual-luciferase reporter assay validated the relationship between NKX2-1-AS1 and miR-96-5p as well as the connection between miR-96-5p and PRDM16.Western blotting was performed to detect the effect of miR-96-5p overexpression on PRDM16 in CAL-62 cells overexpressed with NKX2-1-AS1.Plate clone formation,scratch,and Transwell assays were used to detect the effects of PRDM16knockdown on the proliferation,migration,and invasion of CAL-62 cells overexpressing NKX2-1-AS1.CAL-62 cells were injected subcutaneously into nude mice and the effect was observed of PRDM16knockdown on the growth of transplanted tumors of CAL-62 cells overexpressing NKX2-1-AS1.Results The bioinformatics analysis revealed that the NK2-1-AS1/miR-96-5p/PRDM16 axis was involved in regulating ATC development.The dual-luciferase reporter assay demonstrated that NKX2-1-AS1 bound to miR-96-5p and miR-96-5p bound to PRDM16.NKX2-1-AS1 overexpression upregulated PRDM16 protein expression in CAL-62 cells,while miR-96-5p overexpression reversed this phenomenon.NKX2-1-AS1 overexpression inhibited CAL-62 cellular proliferation,migration,and invasion in vitro and transplanted tumor growth in vivo,while knocking down PRDM16 reversed these phenomena.Conclusion NK2-1-AS1 may compete with miR-96-5p as an endogenous RNA to bind to its downstream target gene,PRDM16,and upregulate its expression,thus inhibiting ATC cell proliferation,migration,and invasion in vitro and transplanted tumor growth in vivo.

Objective:This study aims to explore the application value of the "liftoff" modular method in robot-assisted laparoscopic surgery for complex adrenal tumors.Methods:We retrospectively analyzed the clinical data of 15 patients with complex adrenal tumors treated at the General Hospital of Southern Theater Command from May 2022 to June 2023. The cohort comprised 5 males and 10 females with an average age of (47.6±7.8) years and a body mass index (BMI) of 26.5 (23.8-27.9) kg/m 2. Among the patients, 3 had a BMI ≥28 kg/m 2, 2 had diabetes, 6 had hypertension, and 1 had coronary heart disease. Preoperative endocrine hormone examination revealed abnormal blood catecholamines in 5 cases and abnormal blood cortisol in 2 cases. Ultrasound and CT scans indicated that 9 tumors were located on the left side and 6 on the right, with 4 cases showing tumor compression on adjacent large blood vessels or organs. The average tumor diameter was (7.61±2.79) cm, with 10 cases having a diameter ≥ 6 cm. All patients underwent laparoscopic adrenalectomy assisted by robots through the transperitoneal approach. The surgeries were performed in a lateral position under general anesthesia. The "liftoff" modular method was utilized to separate the treatment of adrenal tumors into lateral, medial, dorsal, cephalic, and adrenal renal plane sides. Tumors were appropriately manipulated during the operations to achieve a "liftoff" shape. Different modular dissociation steps were adopted based on the size and location of the left and right adrenal tumors. The left adrenal gland was dissected in the order of medial and dorsal, adrenal renal plane side, and lateral and cephalic sides, while the right adrenal gland was dissected in the order of lateral and dorsal, adrenal renal plane side, and medial and cephalic sides. Postoperative related indicators and follow-up status of patients were recorded and analyzed. Results:All 15 surgeries were successfully completed without any conversions to open adrenalectomy, with an average operation time of 118 (102-130) minutes and an average intraoperative blood loss of 102 (69-163) ml. The postoperative drainage time was 4 (3-5) days, and the postoperative hospital stay was 6 (4-7) days. The postoperative pathological diagnoses included 5 cases of pheochromocytoma, 3 cases of macronodular adrenal hyperplasia, 6 cases of adrenocortical adenoma, and 1 case of myelolipoma. Follow-up for 6-12 months after surgery showed good recovery and no recurrence.Conclusions:The application of the "liftoff" modular method in robot-assisted laparoscopic surgery for complex adrenal tumors is safe and feasible. It efficiently aids in tumor removal and holds significant clinical application value.

Objective:To explore the impact of early and late antibody-mediated rejection (AMR) on treatment options and allograft outcomes after kidney transplantation (KT).Methods:From January 2013 to December 2022, the study retrospectively enrolled 141 KT allograft recipients receiving allograft biopsy and diagnosed as AMR according to the Banff 2019 criteria. Recipients with a diagnosis of AMR within 30 days post-KT were classified into early AMR group (n=19) while the remainders assigned as late AMR group (n=122). The outcome endpoints included recipient survival rate, death-censored graft survival rate, follow-up estimated glomerular filtration rate (eGFR) and immunodominant donor-specific antibody (DSA) intensity. Wilcoxon's test was utilized for assessing the differences in eGFR and DSA intensity while Kaplan-Meier curve and Log-rank test were employed for evaluating graft survival impact. Treatment regimens for AMR were collected and categorized.Results:The median follow-up duration was 2.6(1.2, 5.2) year. No graft failure was noted in early AMR group while 44 recipients in late AMR group experienced graft failure, with 34 cases (77.2%) due to AMR progression. The 5-year death-censored graft survival rate was significantly better in early AMR group than that in late AMR group [100% vs 60.1%(50.5%, 71.6%), P=0.002]. The one-year change in eGFR for early AMR group was significantly superior to that of late AMR group [19.3(-2.6, 38.1) vs -3.3(-14.0, 5.4), P=0.001]. One-year mean fluorescent intensity (MFI) of early AMR group was 1 158(401.5, 3 126.5). It was significantly lower than that when diagnosed with early AMR [3 120.5(2 392.8, 9 340.0)] and one-year MFI of late AMR group [8 094(2 251.5, 13 560.5)] ( P=0.005, P<0.001). Early AMR group primarily received standard treatment (3/19, 15.8%) and regimens centered on rituximab and/or bortezomib (7/19, 43.8%). Late AMR group mainly received standard (16/122, 13.1%) or intensified regimens (9/122, 7.4%) and regimens focused upon rituximab and/or bortezomib (32/122, 26.2%) and MP monotherapy (21/122, 17.2%). Conclusion:The outcome for early AMR is significantly better than that for late AMR. For early AMR, early and robust immunosuppression is recommended. For late AMR, early detection and timely treatment are crucial and individualized strategies should be implemented.

Anaplastic thyroid carcinoma(ATC)is the most aggressive malignancy with poor prognosis.The pathogenesis of ATC is complex,and there is no effective treatment at present.In recent years,with the deep understanding of the genetic(such as BRAF V600E,TP53,TERT,PIK3CA mutations,etc.)and epigenetic(such as histone methylation,histone deacetylation,microRNA regulatory pathways,etc.)changes driving ATC,molecular targeted therapy has brought new hope to ATC patients.This article reviews the molecular mechanisms of ATC and the latest achievements in targeted therapy and other therapies.

Objective:To investigate the expression of HBB in anaplastic thyroid cancer(ATC)cells and its regulatory effect on proliferation,invasion,migration and apoptosis of ATC cells and its potential mechanism.Methods:The expression of HBB in thyroid cancer and paracancerous tissues was analyzed through TIMER database.The correlation between the expression of HBB and the overall survival time of thyroid cancer patients was analyzed through KM-plotter database.The expression of HBB mRNA in ATC cells was detected by RT-qPCR.The HBB knockout or overexpression plasmid was transfected into ATC cells.The expression of HBB protein was detected by Western blot.The proliferation activity was detected by CCK-8 assay.The migration and invasion ability was detected by Transwell assay.The apoptosis was detected by flow cytometry.The expression of β-catenin was detected by Western blot.Results:The expression of HBB was low in thyroid cancer,and the overall survival time of patients with high expression of HBB was high.The expression of HBB protein was down-regulated in ATC cells.Knockout of HBB increased the ability of proliferation,migration and invasion of ATC cells and the expression of β-catenin protein,and inhibited apoptosis.However,overexpression of HBB decreased the ability of proliferation,migration and invasion of ATC cells and the expression of β-catenin protein,and promoted apoptosis.Conclusions:High HBB expression is associated with higher overall survival in patients with thyroid cancer.It may inhibit the proliferation,migration and invasion of ATC cells and promote apoptosis through Wnt/β-catenin signal pathway.

Objective To investigate the serum levels of peroxisome proliferator-activated receptor-γ coactivator-1α(PGC-1α)and fibronectin type Ⅲ domain-containing protein 5(FNDC5)in patients with hypertensive cerebral hemor-rhage and their association with disease severity and prognosis.Methods A total of 80 patients with hypertensive cere-bral hemorrhage who were diagnosed and treated in our hospital from July 2019 to February 2022 were enrolled as case group,and 80 individuals undergoing physical examination were enrolled as control group.ELISA was used to measure the serum levels of PGC-1α and FNDC5,and the receiver operating characteristic(ROC)curve was used to investigate their value in predicting the prognosis of patients with hypertensive cerebral hemorrhage.The logistic regression analysis was used to investigate the influencing factors for poor prognosis in patients with hypertensive cerebral hemorrhage.Results The case group had significantly lower serum levels of PGC-1α and FNDC5 than the control group(P<0.05),and the good prognosis group also had significantly higher serum levels of PGC-1α and FNDC5 than the poor prognosis group.Disease severity,PGC-1α,and FNDC5 were influencing factors for poor prognosis in patients(P<0.05).Serum PGC-1α and FNDC5 alone or in combination had an area under the ROC curve of 0.957,0.937,and 0.985,respec-tively,in predicting poor prognosis in patients with hypertensive cerebral hemorrhage.Conclusion There are low expres-sion levels of PGC-1α and FNDC5 in patients with hypertensive cerebral hemorrhage,which are associated with the sever-ity and prognosis of patients.Both of them are independent protective factors for prognosis and have a certain application value in evaluating prognosis in clinical practice.

[Objective] To explore the efficacy and safety of retrograde intrarenal surgery (RIRS) using a flexible negative pressure suction sheath in the treatment of upper urinary tract stones >2 cm in diameter, to provide reference for the diagnosis and treatment of such disease. [Methods] Clinical data of 155 patients who underwent surgery for upper urinary tract stones during Nov.2022 and Nov.2023 at the Second Affiliated Hospital of Shaanxi University of Chinese Medicine were retrospectively analyzed.The patients were divided into 3 groups: percutaneous nephrolithotripsy (PCNL) group (n=54), conventional sheath RIRS group (n=41), and flexible sheath RIRS group (n=60). The general and clinical data of the 3 groups were compared. [Results] The PCNL group had more patients with severe hydronephrosis (22.22% vs. 4.88%, 5.00%, P=0.027) and smaller IPA involving the lower calyx [(36.17±17.6)° vs. (48.57±17.56)°, (47.41±10.82)°, P=0.014] than the conventional sheath RIRS group and flexible sheath RIRS group.Three days after operation, the stone-free rate (SFR) was 90.74%, 53.66% and 78.33% in the PCNL, conventional sheath RIRS, and flexible sheath RIRS groups, respectively (P<0.05). At 1 month postoperatively, the SFR was 92.59%, 73.17%, and 81.67%, with no statistically significant difference between the PCNL and flexible sheath RIRS groups (P>0.05), but was higher than that in the conventional sheath RIRS group (P<0.05). The PCNL group had shorter operation time than the two RIRS groups [(65.22±17.67) min vs. (91.73±20.57) min, (94.38±24.75) min, P<0.001], longer postoperative hospital stay [(5.0(4.0, 7.0) d vs.3.0(2.0, 4.0) d, 3.0(2.0, 4.0) d, P<0.001], greater decrease in hemoglobin level [(18.00±5.78) g/L vs. (5.57±5.16) g/L, (7.42±5.09) g/L, P<0.001], and higher visual analogue scale (VAS) score [(4.83±1.48) min vs. (2.95±1.07) min, (3.05±1.21) min, P<0.001], while there was no difference between the two RIRS groups (P>0.05). The costs were lower in the flexible sheath RIRS group than in the conventional sheath RIRS group but higher than in the PCNL group [(23 311.19±1 341.20)yuan vs.(24 550.49±1 172.51)yuan, (15 351.97±1 101.4)yuan, P<0.001]. The overall incidence of complications was similar among the three groups, but stone street occurred only in the conventional sheath RIRS group. [Conclusion] For the treatment of patients with upper urinary tract stones >2 cm, RIRS has shorter postoperative hospital stay, lower hemoglobin decrease, and lower VAS score compared to PCNL; the early postoperative SFR of flexible sheath RIRS is superior to that of conventional sheath RIRS, and the 1-month SFR is comparable to that of PCNL, with a low incidence of stone street.
