OBJECTIVE: To investigate the effect of innovative perioperative pain management on prostate cancer patients with hematuria undergoing prostatic artery embolization (PAE). METHODS: A total of 60 patients undergoing PAE in the Interventional Therapy Department of General Hospital of Eastern Theater Command from May 2024 to January 2025 were selected by convenience sampling method and randomly divided into the intervention group and the control group, with 30 patients in each group. The control group received traditional pain management of nursing. An innovative perioperative pain management was performed in intervention group including preoperative "body-mind-pain" holistic assessment and preparation, intraoperative humanistic care and real-time support, postoperative multimodal analgesia and rehabilitation, dynamic monitoring and closed-loop feedback. The pain degree after 6 hours, 1 day, 3 days and 1 week of the operation, and the quality of life after 1 week of operation, as well as nursing satisfaction at discharge were compared between the two groups. RESULTS: The VAS scores of the intervention group were significantly lower than those of the control group after 6 hours, 1 day, 3 days and 1 week of operation (P<0.05). One week after the operation, the quality of life in the observation group was higher than that of the control group significantly (P<0.05). The nursing satisfaction of the observation group was significantly higher than that of the control group at discharge(P<0.05). CONCLUSION The application of innovative perioperative pain management can alleviate pain of patients with PAE, which improves the quality of life and nursing satisfaction of patients, and is conducive to the rehabilitation of patients.

Tauopathies, including Alzheimer's disease (AD), are a series of neurodegenerative diseases characterized by pathological accumulation of the microtubule-associated protein tau. Since the abnormal modification and deposition of tau in nerve cells are crucial for tauopathy etiology, methods for reducing tau levels, such as promoting tau degradation, may become effective strategies for disease treatment. Herein, we identified that sorafenib significantly reduced total tau and phosphorylated tau levels through screening FDA-approved drugs. We showed that sorafenib treatment attenuated cognitive deficits and tau pathologies in PS19 tauopathy model mice. Mechanistically, we found that sorafenib inhibited multiple kinases involved in tau phosphorylation and promoted autophagy. Importantly, we further demonstrated that sorafenib also promoted the expression of the E3 ubiquitin ligase FBXW7, which could bind tau and mediate tau degradation through the ubiquitin-proteasome pathway. Finally, we showed that FBXW7 expression decreased in the brains of AD patients and tauopathy model mice, and that overexpression of FBXW7 in the hippocampus attenuated cognitive deficits and tau pathologies in PS19 mice. These results suggest that sorafenib may be a promising treatment option for tauopathies by promoting tau degradation and reducing tau phosphorylation, and that targeting FBXW7 could also serve as an alternative therapeutic strategy for tauopathies.

OBJECTIVE: Huachansu injection (HCSI), a promising anti-cancer Chinese medicine injection, has been reported to have the potential for reducing the toxicity of chemotherapy and improving the quality of life for colorectal cancer (CRC) patients. The objective of this study is to explore the synergistic and detoxifying effects of HCSI when used in combination with irinotecan (CPT-11). METHODS: To investigate the effect of HCSI on anti-CRC efficacy and intestinal toxicity of CPT-11, we measured changes in the biological behavior of LoVo cells in vitro, and anti-tumor effects in LoVo cell xenograft nude mice models in vivo. Meanwhile, the effect of HCSI on intestinal toxicity and the uridine diphosphate-glucuronosyltransferase 1A1 (UGT1A1) expression was investigated in the CPT-11-induced colitis mouse model. Subsequently, we measured the effect of HCSI and its 13 constituent bufadienolides on the expression of UGT1A1 and organic anion transporting polypeptides 1B3 (OATP1B3) in HepG2 cells. RESULTS: The combination index (CI) results showed that the combination of HCSI and CPT-11 exhibited a synergistic effect (CI < 1), which significantly suppressing the LoVo cell migration, enhancing G2/M and S phase arrest, and inhibiting tumor growth in vivo. Additionally, the damage to intestinal tissues was attenuated by HCSI in CPT-11-induced colitis model, while the increased expression of UGT1A1 in HepG2 cells and in mouse was observed. CONCLUSION The co-therapy with HCSI alleviated the intestinal toxicity induced by CPT-11 and exerted an enhanced anti-CRC effect. The detoxifying mechanism may be related to the increased expression of UGT1A1 and OATP1B3 by HCSI and its bufadienolides components. The findings of this study may serve as a theoretical insights and strategies to improve CRC patient outcomes.

Objective To develop a matrix metalloproteinase(MMP)-responsive hyaluronic acid(HA)-based controlled-release material for brain-derived neurotrophic factor(BDNF)to provide a novel therapeutic strategy for intervention and repair of traumatic brain injury(TBI).Methods HA was modified with amination,followed by condensation with Suflo-SMCC carboxyl group to form amide,and then linked with glutathione(GSH)to synthesize HA-GSH.The recombinant glutathione S-transferase(GST)-tissue inhibitor of metalloproteinase(TIMP)-BDNF(GST-TIMP-BDNF)expression plasmid was constructed using molecular cloning technique with double enzyme digestion by Bam H Ⅰ and Eco R Ⅰ.The recombinant GST-TIMP-BDNF protein was expressed in the Escherichia coli prokaryotic expression system,and purified by ion exchange chromatography,confirmed by Western blotting.MMP diluents were supplemented with PBS,MMP inhibitor marimastat,and varing concentrations(0.4,0.6,0.8 mg/ml)of GST-TIMP-BDNF or GST-BDNF.MMP-2 activity was analyzed using an MMP activity detection kit to evaluate the inhibitory effect of the recombinant protein on MMP.Primary rat neurons were extracted and cultured to establish an iron death model induced by RSL3.The effect of recombinant protein GST-TIMP-BDNF on neuronal injury was detected by immunofluorescence staining.Results MRI hydrogen spectrum identification confirmed the successful synthesis of HA-GSH.Western blotting results showed the successful expression of the recombinant protein GST-TIMP-BDNF containing the GST tag using the E.coli prokaryotic expression system.MMP activity detection results indicated that the recombinant protein GST-TIMP-BDNF had a superior inhibitory effect on MMP-2 activity compared to GST-BDNF(P<0.05).Immunofluorescence staining results showed a significant increase in fluorescence intensity in rat neurons treated with GST-TIMP-BDNF after RSL3 induction(P<0.05).Conclusion A MMP-responsive HA-based BDNF controlled-release material has been successfully developed,exhibiting a protective effect on neuron damage.

Objective To study the effects of Guizhi Shaoyao Zhimu Decoction on factors related to bone destruction and bone protection in rats with collagen-induced arthritis(CIA)based on osteopro-tegerin(OPG)/receptor activator of NF-κB ligand(RANKL)/receptor activator of NF-κB(RANK)signaling pathway.Methods According to the body weight,60 female Wistar rats were randomly di-vided into the following six groups:the normal group,the model group,the Triperygium wilfordii mul-tiglucoside group(0.01 g/kg),the Guizhi Shaoyao Zhimu Decoction low-dose group(8.6 g/kg),the Guizhi Shaoyao Zhimu Decoction medium-dose group(17.2 g/kg),and the Guizhi Shaoyao Zhimu Decoction high-dose group(34.4 g/kg)(n=10 rats per group).The rats in all groups except for the normal group were given 100 μg bovine type Ⅱ collagen on the 1st and 8th days to establish the CIA model,and was injected into the left foot sole and tail root of the rats.After the successful modeling,the rats were treated by gavage for 4 weeks.The general state,body weight,and arthritis index(AI)score of rats were recorded,and the contents of RANKL and OPG in rat serum were determined by enzyme-linked immunosorbent assay.The mRNA and protein expressions of RANKL,RANK,and OPG in the ankle joint were determined through real-time PCR and Western blotting,respectively.Results Com-pared with the normal group,the general state of the model group was poor,the toe swelling was obvious,the AI score was increased,the serum RANKL content was increased,the serum OPG content was de-creased,and the mRNA and protein expressions of RANKL and RANK in the ankle joint were increased(P＜0.05).Compared with the model group,the degree of toe swelling and the AI score of rats in the Guizhi Shaoyao Zhimu Decoction low-,medium-,and high-dose groups were decreased,the serum RANKL content was decreased,the serum OPG content was increased,the mRNA and protein expres-sions of RANKL and RANK in the ankle joint were decreased,the mRNA and protein expressions of OPG were increased,and the RANKL/OPG ratio of the ankle joint was decreased(P＜0.05).Conclusion Guizhi Shaoyao Zhimu Decoction can improve the destruction of joint bone in CIA rats,and its mecha-nism of action may be related to reducing RANKL level,reducing RANKL/OPG ratio,and regulating bone balance.

Objective To evaluate and analyze the accuracies of 3 software solutions based on deep learning techniques in the automatic segmentation of head and neck organs at risk(OAR).Methods The automatic segmentation accuracies of 3 software(PV-iCurve,RT-Mind,and AccuContour)were evaluated with Dice similarity coefficient(DSC),Hausdorff distance(HD),center of mass deviation(COMD),false negative rate(FNR),false positive rate(FPR),Jaccard coefficient(JC),sensitivity index(SI),and inclusive index(II)using the manual contours of head and neck OAR as the gold standard.Results The FNR,JC,SI of brain,the FPR,II of brainstem,the FPR,FNR,JC,SI of eye_L,the FPR,FNR,SI,II of mandible,the FPR,FNR,SI,II of parotid_L,and the DSC,FPR,JC,II of spinal cord manifested significant differences among the 3 software(P<0.05);but the HD,FNR,SI of brainstem,and the HD of spinal cord revealed trivial differences among the 3 software(P>0.05).Conclusion Through the comparison of multiple parameters,it is found that the accuracies of 3 software are different in OAR segmentation,which makes it difficult to make overall horizontal comparisons.Therefore,these parameters are for reference only and cannot be used as criteria for evaluating the segmentation results in clinic.Although all 3 software achieve preferable segmentation outcomes,scrutiny and manual modifications before clinical practice are still necessary.

Ischemic stroke(IS)is a devastating neurological disease commonly around the world.Although modern medicine has recognized the confined mechanisms in the pathological process of cerebral ischemia,it has never been enough for the treatment of IS.Recent studies have confirmed the vital role of mitochondrial dysfunction in neuronal injury after cerebral ische-mia,thereby exerting a potential target for prevention and treat-ment of IS.Herein,we review the main molecular mechanisms of neuronal injury and death by mitochondrial dyshomeostasis under the condition of ischemia/hypoxia,especially mitochon-drial permeability transition pore opening,oxidative stress and apoptotic signaling.Given remodeling of mitochondrial function as a new idea for the management of IS,some emerging strate-gies containing mitochondrial antioxidant,mitophagy regulation and mitochondrial transfer also raise concern in this paper.

OBJECTIVE: To observe the effect of needle-knife on the chondrocyte apoptosis of knee joint in rabbits with knee osteoarthritis (KOA) based on the CircSERPINE2-miR-1271-5P-E26 specific transformation-related gene (ERG) axis, and to explore the mechanism of needle-knife for KOA. METHODS: Thirty-six New Zealand white rabbits were randomly divided into a normal group, a model group, a needle-knife group and a sham needle-knife group, 9 rabbits in each group. The rabbits in the model group, the needle-knife group and the sham needle-knife group were treated with modified Videman method to prepare KOA model. After successful modeling, the rabbits in the needle-knife group were treated with needle-knife at cord adhesion and nodules near quadriceps femoris tendon and internal and external collateral ligament on the affected knee joint; the rabbits in the sham needle-knife group were treated with sham needle-knife baside the needle insertion point of the needle-knife group (needle-knife was only inserted, without any operation). The treatment was given once a week, 3 times in total. The Lequesne MG behavioral score was used to evaluate the knee joint damage in each group before and after intervention. After intervention, HE staining and transmission electron microscopy were used to observe the cartilage tissue morphology and ultrastructure of chondrocytes in the knee joint in each group; TUNEL method was used to detect the level of chondrocyte apoptosis in the knee joint; real-time fluorescence quantitative PCR was used to detect the expression of CircSERPINE2, miR-1271-5P and ERG mRNA in knee cartilage tissue in each group. RESULTS: After intervention, compared with the normal group, the Lequesne MG behavioral score in the model group was increased (P<0.01). Compared with the model group and the sham needle-knife group, the Lequesne MG behavioral score in the needle-knife group was decreased (P<0.01). In the model group and the sham needle-knife group, the number of chondrocytes and organelles was decreased, the cell nucleus was shrunk, mitochondria was swelling or disappeared; in the needle-knife group, the number of chondrocytes and organelles was increased, the cell nucleus was not obviously shrunk and the mitochondria was not obviously swelling. Compared with the normal group, the level of chondrocyte apoptosis in the model group was increased (P<0.01); compared with the model group and the sham needle-knife group, the level of chondrocyte apoptosis in the needle-knife group was decreased (P<0.01, P<0.05). Compared with the normal group, the expression of CircSERPINE2 and ERG mRNA in the model group was decreased (P<0.01), and the expression of miR-1271-5P mRNA was increased (P<0.01); compared with the model group and the sham needle-knife group, the expression of CircSERPINE2 and ERG mRNA in the needle-knife group was increased (P<0.01), and the expression of miR-1271-5P mRNA was decreased (P<0.01). CONCLUSION Needle-knife could reduce the knee joint damage and chondrocyte apoptosis in KOA rabbits, which may be related to up-regulating the expression of CircSERPINE2 and ERG mRNA, and inhibiting the expression of miR-1271-5P mRNA.

Objective: To introduce a classification of alar retraction, and to discuss the therapeutic strategy of alar retraction with cartilage graft and the satisfaction evaluation of patients after operation. Methods: A retrospective analysis was performed on 88 patients with alar retraction admitted to the Department of Plastic and Aesthetic (Burn) Surgery, the Second Xiangya Hospital of Central South University from January 2015 to December 2020, including 20 males and 68 females, aged 20 to 48 years, with an average age of 28.98 years. All patients underwent external rhinoplasty according to a series of treatment plans determined by the classification of alar retraction based on nostril exposure. Visual Analogue Scale (VAS) and Rhinoplasty Outcomes Evaluation (ROE) were used to conduct satisfaction survey before and 12 months after operation. Wilcoxon signed-rank test was used to analyze patient satisfaction. Results: A total of 88 patients were included in this study. According to the classification of alar retraction based on nostril exposure, 45 cases were mild, 23 cases were moderate, and 20 cases were severe. There were 16 cases of unilateral and 72 cases of bilateral alar retraction. The patients were followed up for 12 to 18 months, with an average of 13.37 months. The VAS score and ROE score after each type of surgery were higher than those before surgery, with statistically significant (all P<0.05). Among them, the difference in VAS score (6.75±1.29) and in ROE satisfaction (67.70±7.38) of patients with severe alar retraction were the most significant improvement. Conclusion: The classification of alar retraction based on nostril exposure in the frontal view can comprehensively evaluate the severity of alar retraction, and makes the treatment algorithms systematic and comprehensive. The satisfaction of patients is relatively high.
